to the contrary herein, if either (i) the Base Conversion Price (as defined in the Certificate of Designations) is less than $11.60 or (ii) the value of the consideration paid to Traxis
upon the Acquisition Closing is less than $255.0 million, valuing all shares of Common Stock issued to Traxis at $10 per share, then the Company shall not have any obligation to sell any Preferred Shares to any such Subscriber. The Company shall
have the right, upon written notice to such Subscriber (the “Accordion Election Notice”), to require the purchase by such Subscriber of such Accordion Subject Preferred Shares, as contemplated by the foregoing clauses 1(b) and (y).

 2. Delivery of Subscription Amount; Acceptance of Subscriptions; Delivery. Each Subscriber understands and agrees that this subscription is made

subscription and (ii) there occurs the simultaneous Acquisition Closing. If such acceptances do not occur on or prior to the earliest of (x) the Acquisition Closing or (y) the date on which the Purchase Agreement is terminated in
accordance with its terms (the “Termination Date”), such Subscriber’s subscription shall automatically be deemed rejected (the “Subscription Rejection”). 

(c) The payment of the Preferred Subscription Amount will be returned promptly, without interest, to each Subscriber, as applicable, if the
applicable subscriptions are rejected in whole or in part or if the Preferred Offering is withdrawn or canceled.

and regulations promulgated thereunder, and applicable state securities laws. 
 (b) None of the Subject Preferred Shares or the Underlying
Common may be directly or indirectly transferred, disposed of or otherwise monetized in any manner whatsoever, except in a transaction that is in compliance with the Securities Act and applicable state securities laws. Except as provided in the
Registration Rights Agreement, it shall be a condition to any such transfer that the Company shall be furnished with a written opinion of counsel to the holder of such Subject Preferred Shares (or the Underlying Common, as applicable), reasonably
satisfactory to the Company (as determined by the Company within 3 Business Days of its receipt of such written opinion), to the effect that the proposed transfer would be in compliance with the Securities Act and applicable state securities laws;
provided that the Company shall not require such written opinion of counsel if, acting in its reasonable discretion, if determines that applicable Law does not prohibit any transfers of the Subject Preferred Shares (or the Underlying Common), as
applicable, at such time. “Business Day” shall mean any day that is not a Saturday, a Sunday or a day on which commercial banks in New York City are required or authorized to be closed.

Subscriber hereby represents, warrants and covenants to the Company as follows: 
 (a) Such Subscriber is purchasing the Subject Preferred
Shares (including the Underlying Common) (collectively, the “Subject Shares”) for its own account, not as a nominee or agent, for investment purposes and not with a view towards distribution or resale within the meaning of the

Pursuant to the foregoing, such Subscriber acknowledges that until such time as the resale of the Subject Shares has been registered under the Securities Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant to
an exemption from registration, the certificates representing any Subject Shares acquired by such Subscriber shall bear a restrictive legend substantially as follows (and a stop-transfer order may be placed against transfer of the certificates

acquisition of the Subject Preferred Shares (including the Underlying Common) (collectively, the “Shares”). Such Subscriber understands that the acquisition of the Subject
Preferred Shares (including the Underlying Common) is a speculative investment and involves substantial risks and that such Subscriber could lose such Subscriber’s entire investment. Further, the undersigned has (i) carefully read and

advice regarding the investment, tax and legal merits and consequences of the foregoing, including, without limitation, purchasing and owning the Shares. Such Subscriber has the ability to bear the economic risks of such Subscriber’s investment
in the Company, including a complete loss of the investment, and such Subscriber has no need for liquidity in such investment. 
 (d) Such
Subscriber has been furnished by the Company all information (or provided access to all reasonable information it requested) regarding the business and financial condition of the Company and School Bus, the Company’s expected plans for future
business activities, and the merits and risks of an investment in the Shares which such Subscriber has requested or otherwise needs to evaluate the investment in the Shares. 

(e) Such Subscriber is in receipt of and has carefully read and understands the following items (collectively, the “Disclosure

Company proposed to be voted on pursuant thereto, a copy of which has been made available to such Subscriber. 
 Such Subscriber understands
the significant extent to which certain of the disclosures contained in items (i) and (ii) above shall no longer apply following the acquisition of School Bus in accordance with the Purchase Agreement.

Designations) is based on an assumed pro forma number of shares of Common Stock outstanding of 27,087,500 and an assumed market capitalization of $270,875,000 (without taking into account the issuance of any Preferred Shares) at $10.00 per share.

of and receive answers from the management of the Company concerning the terms and conditions of the proposed transaction and that at no time was such Subscriber presented with or solicited by or through any advertisement, article, leaflet, public
promotional meeting, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or meeting or any other form of general or public advertising or solicitation.

 (g) Such Subscriber acknowledges that it has been advised that: 

(i) The Subject Shares offered hereby have not been approved or disapproved by the SEC or any state securities commission nor has the SEC or
any state securities commission passed upon the accuracy or adequacy of any representations by the Company. Any representation to the contrary is a criminal offense. 

(ii) In making an investment decision, such Subscriber must rely on its own examination of the Company, the Acquisition, School Bus, the
Shares and the terms of the Preferred Offering, including the merits and risks involved. The Shares have not been recommended by any federal or state securities commission or regulatory authority. Furthermore, the foregoing authorities have not
confirmed the accuracy or determined the adequacy of any representation. Any representation to the contrary is a criminal offense. 
 (iii)
The Subject Shares will be “restricted securities” within the meaning of Rule 144 under the Securities Act, are subject to restrictions on transferability and resale and may not be transferred or resold except as permitted under the

connection with the purchase of the Subject Preferred Shares, (b) to delegate authority pursuant to power of attorney and (c) to purchase and hold such Shares and the Underlying Common; (ii) the signature of the party signing on
behalf of such Entity is binding upon such Entity; and (iii) such Entity has not been formed for the specific purpose of acquiring such Shares, unless each beneficial owner of such entity is a “qualified institutional buyer” within
the meaning of Rule 144A under the Securities Act, is qualified as an accredited investor within the meaning of Rule 501(a) of Regulation D promulgated under the Securities Act and has submitted information substantiating such individual
qualification.

creditors’ rights generally; (ii) equitable limitations on the availability of specific remedies; (iii) principles of equity (regardless of whether such enforcement is considered in a proceeding in Law or in equity); and (iv) to

damages would not be an adequate remedy at Law if any Subscriber fails to perform in any material respect any of its obligations hereunder and accordingly agree that each party and Traxis, in addition to any other remedy to which it may be entitled
at Law or in equity, shall be entitled to seek an injunction or similar equitable relief restraining such party from committing or continuing any such breach or threatened breach or to seek to compel specific performance of the obligations of any
other party under this Agreement, without the posting of any bond, in accordance with the terms and conditions of this Agreement in any court of the United States or any State thereof having jurisdiction, and if any action should be brought in
equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at Law. 

13. Obligations Irrevocable. The obligations of each Subscriber to make its subscription provided for hereunder shall be irrevocable, except with the
consent of the Company and Traxis, until the Subscription Rejection. 
 14. Agreement. This Agreement and the Registration Rights Agreement
constitutes the entire agreement of the Subscribers and the Company relating to the matters contained herein and therein, superseding all prior contracts or agreements, whether oral or written. The headings of this Agreement are for convenience of
reference and shall not form part of, or affect the interpretation of, this Agreement. 
 15. Governing Law; Jurisdiction. This Agreement shall be
governed by and construed in accordance with the laws of the State of Delaware, without regard to the principles of conflicts of law thereof that would require the application of the laws of any jurisdiction other than New York. Each of the parties
consents to the non-exclusive jurisdiction of the federal courts whose districts encompass any part of the District of Delaware or the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks
jurisdiction, then in the 

  
 17 








 
applicable Delaware state court), with any dispute arising under this Agreement and hereby waives, to the maximum extent permitted by law, any objection, including any objection based on forum
non conveniens, to the bringing of any such proceeding in such jurisdictions. 
 16. Severability. If any provision of this Agreement or the
application thereof to any Subscriber or any circumstance shall be held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other subscriptions or circumstances shall not be affected
thereby and shall be enforced to the greatest extent permitted by Law. 
 17. Construction. The headings in this Agreement are inserted for
convenience and identification only and are not intended to describe, interpret, define, or limit the scope, extent or intent of this Agreement or any provision hereof. The rule of construction that an agreement shall be construed strictly against
the drafter shall not apply to this Agreement. 
 18. Counterparts; Facsimile. This Agreement may be executed in any number of counterparts, each of
which when so executed and delivered shall be deemed to be an original and all of which together shall be deemed to be one and the same agreement. A facsimile or other electronic transmission of this signed Agreement shall be legal and binding on
all parties hereto. 
 19. Counsel. Each Subscriber hereby acknowledges that the Company and its counsel represent the interests of the Company and
not those of any Subscriber in any agreement (including this Agreement) to which the Company is a party. 
 20. Confidentiality. Without limiting any
of Subscriber’s pre-existing confidentiality obligations, Subscriber shall not, for a period of two years following the date hereof, without the Company’s prior written consent, disclose to any other person or entity the nature, extent or
fact that Subscriber is entering this Agreement or the terms and conditions hereof, or any information Subscriber may receive in connection with this Agreement (in each case to the extent the Company has communicated the confidentiality thereof)
other than (a) pursuant to the order of any court or administrative agency or in any pending legal or administrative proceeding, or otherwise as required by applicable law or compulsory legal process (in which case Subscriber agrees, to the
extent practicable and not prohibited by applicable Law, to inform the Company promptly thereof prior to such disclosure), (b) upon the request or demand of any regulatory authority having jurisdiction over Subscriber, (c) to the extent
that such information is or becomes publicly available other than by reason of disclosure by Subscriber in violation of this Agreement, or (d) to Subscriber’s Affiliates and to Subscriber’s and its Affiliates’ employees, legal
counsel, independent auditors and other agents (collectively “representatives”) who need to know such information and who are informed of the confidential nature of such information and are or have been advised of their obligation to keep
information of this type confidential. Subscriber will cause all of its and its Affiliate’s representatives to comply with the confidentiality provisions of this Agreement as fully as if they were a party hereto and will be responsible for a
breach of the confidentiality provisions of this Agreement by any such representatives. “Affiliate” shall mean affiliate as such term is defined in Rule 12b-2 of the Exchange Act.

 8 








 
accrue for all fiscal periods during which the Preferred Stock is outstanding, regardless of whether the Company has earnings in any such period, whether there are funds legally available for the

 (c) No dividends or other distributions (other than a dividend or
distribution payable solely in shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock) and cash in lieu of fractional shares) may be declared, made or paid, or set apart for payment upon,
any Parity Stock or Junior Stock, nor may any Parity Stock or Junior Stock be redeemed, purchased or otherwise acquired for any consideration (or any money paid to or made available for a sinking fund for the redemption of any Parity Stock or Junior

fractional shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Parity Stock), (ii) payments in connection with the satisfaction of employees’ tax withholding obligations pursuant to employee
benefit plans or outstanding awards (and payment of any corresponding requisite amounts to the appropriate governmental authority) and (iii) the payment of the Special Dividend Withholding Tax), unless all Accumulated Dividends (as of the date

Junior Stock and cash in lieu of fractional shares) may be declared, made or paid, or set apart for payment upon, any Junior Stock (except payments in connection with the satisfaction of employees’ tax withholding obligations pursuant to
employee benefit plans or outstanding awards (and payment of any corresponding requisite amounts to the appropriate governmental authority) and the payment of the Special Dividend Withholding Tax) unless the payment of the dividend in respect of the
Preferred Stock for the most recent dividend period ending on or prior to the date of such declaration or payment has been declared and paid in cash or declared and a sum of cash sufficient for the payment thereof set aside for such payment.
Notwithstanding the foregoing, if full dividends have not been paid on the Preferred Stock and any Parity Stock, dividends may be declared and paid on the Preferred Stock and such Parity Stock so long as the dividends are declared and paid pro rata
so that the amounts of dividends declared per share on the Preferred Stock and such Parity Stock shall in all cases bear to each other the same ratio that accumulated and unpaid dividends per share on the shares of Preferred Stock and such Parity
Stock bear to each other at the time of declaration. 

  
 9 








 (d) Holders of shares of Preferred Stock shall not be entitled to any dividend, whether payable
in cash, property or stock, in excess of full cumulative dividends (it being understood that this Section 3(d) shall not limit the Company’s obligations pursuant to Section 3(a)).

and no interest or dividends on such payment will accrue or accumulate as the case may be, in respect of the delay. 
 (f) The holders of
shares of Preferred Stock at the close of business on a Dividend Record Date shall be entitled to receive the dividend payment on those shares on the corresponding Dividend Payment Date notwithstanding the conversion of such shares in accordance
with Sections 8 or 9 following such Dividend Record Date or the Company’s default in payment of the dividend due on such Dividend Payment Date. In the case of conversion of shares of Preferred Stock pursuant to Section 5 following the
close of business on a Dividend Record Date but prior to the corresponding Dividend Payment Date, the holders of such shares shall not be entitled to receive the corresponding dividend payment following conversion (it being understood that the value
thereof is included in the conversion terms set forth in Section 5). 
 (g) Notwithstanding anything herein to the contrary, to the
extent that any Holder’s right to participate in any Dividend would result in the Holder exceeding the Beneficial Ownership Limitation, then the rights appurtenant to such Dividend to which such Holder is entitled pursuant hereto shall be
limited to the same extent provided in Section 11 hereof. 
 (h) Except as provided in Section 8, the Company shall make no
payment or allowance for unpaid dividends, whether or not in arrears, on converted shares of Preferred Stock or for dividends on the shares of Common Stock issued upon conversion. 

 

	(4)	Method of Payment of Dividends.  

 (a) Subject to the restrictions set
forth herein, the Company may elect to pay any dividend on the Preferred Stock: (i) in cash; (ii) by delivery of shares of Preferred Stock; (iii) by delivery of shares of Common Stock; or (iv) through any combination of cash,
Preferred Stock and/or Common Stock. 
 (b) If the Company elects to make a dividend payment, or any portion thereof, in shares of Preferred
Stock, the number of shares deliverable shall be equal to the quotient of (i) the cash amount of such dividend payment that would apply if no payment were to be made in Preferred Stock, or such portion, divided by (ii) $100.00 (as
equitably adjusted by the Board to the extent necessary for any stock splits, combinations or like transactions). 
 (c) If the Company
elects to make a dividend payment, or any portion thereof, in shares of Common Stock, the number of shares deliverable shall be (i) the cash amount of such dividend payment that would apply if no payment were to be made in Common Stock, or such
portion, divided by (ii) the product of (x) the Weighted Average Price of the Common Stock for each of the 10 consecutive Trading Days ending on the second Trading Day immediately preceding such Dividend Payment Date (as equitably
adjusted by the Board to the extent necessary for any stock splits, combinations or like transactions); multiplied by (y) 0.95; provided, that at least 2 Trading Days prior to the beginning of the averaging period described in
(ii)(x) above, the Company shall provide written notice of such election to the Holder. 

  
 10 








 (d) The Company shall make each dividend payment on the Preferred Stock in cash, except to the
extent the Company elects to make all or any portion of such payment in shares of the Preferred Stock or Common Stock (or any combination thereof) as set forth above. The Company shall give Holders notice of any such election and the portion of such
payment that will be made in cash and the portion that will be made in Preferred Stock or Common Stock no later than 12 Trading Days prior to the Dividend Payment Date for such dividend. 

 

	(5)	Conversion Upon a Fundamental Change.  

 (a) The Company must give notice
(a “Fundamental Change Notice”) of each Fundamental Change to all Holders of the Preferred Stock no later than 10 Business Days prior to the anticipated Effective Date (determined in good faith by the Board) of the
Fundamental Change or, if not practicable because the Company is unaware of the Fundamental Change, as soon as reasonably practicable but in any event no later than 1 Business Day after the Company becomes aware of such Fundamental Change. 

(b) Within 15 days following the Effective Date of such Fundamental Change, each Outstanding share of Preferred Stock (for this purpose,
adding any and all accumulated and unpaid dividends as if paid in Preferred Stock in accordance with the terms hereof which Preferred Stock shall be deemed for this purpose to be Outstanding) shall (subject to the limitations set forth in
Section 11), at the election of the Holder thereof pursuant to the delivery of a Notice of Conversion, be converted into a number of shares of Common Stock equal to the greater of (i) the sum of the Conversion Rate on the Effective Date of
such Fundamental Change plus the Fundamental Change Additional Shares and (ii) the quotient of (x) the Liquidation Preference, divided by (y) the greater of (A) the applicable Holder Stock Price and (B) 662/3% of the Closing Sale Price of the Common Stock on the Issue Date (it being understood that for purposes of this Section 5(b), the
Closing Sale Price shall be adjusted proportionally in the event of any stock split, stock dividend, issuance of rights, options or warrants or other event that would result in an adjustment to the Conversion Right pursuant to
Section 8(d)). Notwithstanding anything contained herein to the contrary, prior to the receipt of Shareholder Approval, shares of Preferred Stock shall not be convertible pursuant to this Section 5 in the aggregate into more than
the Conversion Cap. As used herein, “Holder Stock Price” means (i) in the case of a Fundamental Change in which the Holders of Common Stock will receive only cash consideration, the price to be paid (or deemed paid) per share
of Common Stock in such transaction and (ii) in all other cases, the average Closing Sale Price of the Common Stock on the 10 consecutive Trading Days immediately preceding the Effective Date of the Fundamental Change. 

(c) The Fundamental Change Notice shall be given by first-class mail to each record holder of shares of Preferred Stock, at such Holder’s
address as the same appears on the books of the Company. Each such notice shall state (i) the anticipated Effective Date and (ii) that dividends on the Preferred Stock to be converted will cease to accrue on the date immediately preceding
the Effective Date of the Fundamental Change. 

  
 11 








 (d) Whenever any provision of this Certificate of Designations requires the Company to calculate
the Weighted Average Price or Closing Sale Price for purposes of a Fundamental Change over a span of multiple days, the Board shall make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any
event requiring an adjustment to the Conversion Rate where the Record Date of the event occurs, at any time during the period when such Weighted Average Prices or Closing Sale Prices are to be calculated. 

(6) Voting. The shares of Preferred Stock shall have no voting rights except as set forth in this Section 6 or otherwise required by Delaware law.
So long as any shares of Preferred Stock remain Outstanding, unless a greater percentage shall then be required by law, the Company shall not, without the affirmative vote or consent of (a) the Holders of at least 50.1% of the shares of
Preferred Stock Outstanding at the time, voting together as a single class with all series of Parity Stock upon which similar voting rights have been conferred and are exercisable, given in person or by proxy, either in writing or at a meeting,
amend, alter or repeal the provisions of the Amended and Restated Certificate of Incorporation, whether by merger, consolidation or otherwise, so as to materially and adversely affect any right, preference, privilege or voting powers of the shares
of Preferred Stock; provided, however, that so long as any shares of Preferred Stock remain Outstanding with the terms thereof materially unchanged, such amendment, alteration or repeal shall not be deemed to materially and adversely
affect such rights, preferences, privileges or voting powers of Holders of the shares of Preferred Stock and, provided further, that any increase in the amount of authorized preferred stock (including additional Preferred Stock) or the creation or
issuance of any additional shares of Preferred Stock or other series of preferred stock, or any increase in the amount of authorized shares of such series, in each case of Parity Stock or Junior Stock, shall not be deemed to materially and adversely
affect the rights, preferences, privileges or voting powers of Holders of shares of Preferred Stock specified herein and (b) the Required Holders, given in person or by proxy, either in writing or at a meeting, amend, alter or repeal the
provisions of the Amended and Restated Certificate of Incorporation, whether by merger, consolidation or otherwise, so as to effect a Material Change. 
  

	(7)	Liquidation Rights.  

 (a) In the event of any liquidation, winding-up or
dissolution of the Company, whether voluntary or involuntary, each Holder of shares of Preferred Stock shall be entitled to receive and to be paid out of the assets of the Company available for distribution to its stockholders the Liquidation
Preference plus all accumulated and unpaid dividends in respect of the Preferred Stock (whether or not declared) to the date fixed for liquidation, winding-up or dissolution in preference to the holders of, and before any payment or distribution is
made on, any Junior Stock, including, without limitation, the Common Stock. 
 (b) Neither the sale (for cash, shares of stock, securities
or other consideration) of all or substantially all the assets or business of the Company (other than in connection with the liquidation, winding-up or dissolution of the Company) nor the merger or consolidation of the Company into or with any other
Person shall be deemed to be a liquidation, winding-up or dissolution, voluntary or involuntary, for the purposes of this Section 7. 

  
 12 








 (c) After the payment to the Holders of the shares of Preferred Stock of full preferential
amounts provided for in this Section 7, the Holders of Preferred Stock as such shall have no right or claim to any of the remaining assets of the Company. 

(d) In the event the assets of the Company available for distribution to the Holders of shares of Preferred Stock and holders of shares of
Parity Stock upon any liquidation, winding-up or dissolution of the Company, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such Holders are entitled pursuant to this Section 7, no such distribution
shall be made on account of any shares of Parity Stock upon such liquidation, dissolution or winding-up unless proportionate distributable amounts shall be paid on account of the shares of Preferred Stock, equally and ratably, in proportion to the
full distributable amounts for which holders of all Preferred Stock and of any Parity Stock are entitled upon such liquidation, winding-up or dissolution. 
  

	(8)	Conversion.  

 (a) Each Holder of Preferred Stock shall have the right at
any time, at its option, to convert, subject to the terms and provisions of this Section 8, any or all of such Holder’s shares of Preferred Stock into Common Stock at a conversion rate equal to the quotient of (i) the Liquidation
Preference; divided by (ii) the Base Conversion Price (subject to adjustment as provided in this Section 8, the “Conversion Rate”) per share of Preferred Stock (subject to the limitations set forth in
Section 11). Notwithstanding the foregoing, but subject to the Conversion Cap, each Holder of Preferred Stock shall have the right (the “Seven-Year Holder Conversion Right”) at any time after the seven-year
anniversary of the Issue Date, if the then-current Conversion Price exceeds the Weighted Average Price for the Common Stock during any 10 consecutive Trading Days, at its option by delivery of a Notice of Conversion in accordance with
Section 8(b) below no later than 5 Business Days following such 10th consecutive Trading Day, to convert any or all of such Holder’s shares of Preferred Stock into, at the Company’s
sole discretion, either Common Stock, cash or a combination of Common Stock and cash; provided, that the Company shall provide such converting Holder notice of its election within 2 Trading Days of receipt of the Notice of Conversion;
provided further, that in the event the Company elects to issue Common Stock for all or a portion of such conversion, the “Conversion Rate” for such conversion (subject to the limitations set forth in Section 11) shall mean the
quotient of the Liquidation Preference divided by the average Weighted Average Price for the Common Stock during the 20 consecutive Trading Days commencing on the Trading Day immediately following the Trading Day on which the Company provided
such notice. If the Company does not elect a settlement method prior to the deadline set forth, the Company shall be deemed to have elected to settle the conversion entirely in Common Stock. Notwithstanding anything to the contrary herein, prior to
the receipt of Shareholder Approval, shares of Preferred Stock shall not be converted pursuant to this Section 8 in the aggregate into more than 19.99% of the shares of Common Stock outstanding on the Issue Date (subject to appropriate
adjustment in the event of a stock split, stock dividend, combination or other similar recapitalization) (such limitation, the “Conversion Cap”). Upon conversion of any share of Preferred Stock, the Company shall
deliver to the converting Holder, in respect of each share of Preferred Stock being converted, a number of shares of Common Stock equal to the Conversion Rate, together with a cash payment in lieu of any fractional share of Common Stock in
accordance with Section 10, on the third Business Day immediately following the relevant Conversion Date; provided, that upon any Holder’s election to 

  
 13 








 
convert any share or shares of Preferred Stock pursuant to the second sentence of this Section 8(a), the Company shall have the option to deliver the applicable conversion value (or any
portion thereof) in cash in lieu of shares of Common Stock, after providing such Holder at least 2 Business Days’ prior written notice of its election pursuant to this proviso; provided further, that any such payment in cash in
lieu of shares of Common Stock shall be made in an amount equal to the Liquidation Preference for every whole share of Preferred Stock so converted; provided further, that if the conversion value consists (x) solely of cash, then
the Company shall deliver such cash payment to the Holder no later than 3 Trading Days from the receipt of the Notice of Conversion or (y) partially of cash, then the Company shall deliver such cash payment to the Holder simultaneously with the
delivery of the Common Stock included in the conversion value. 
 (b) Before any Holder shall be entitled to convert a share of Preferred
Stock as set forth above, such Holder shall (1) manually sign and deliver an irrevocable notice to the office of the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) in the form included in Exhibit
A hereto (a “Notice of Conversion”) and state in writing therein the number of shares of Preferred Stock to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any
shares of Common Stock, if any, to be delivered and registered, (2) surrender such shares of Preferred Stock, at the office of the Conversion Agent and (3) if required, furnish appropriate endorsements and transfer documents. The
Conversion Agent shall notify the Company of any pending conversion pursuant to this Section 8 on the Conversion Date for such conversion. The date on which a Holder complies with the procedures in this clause (b) is the
“Conversion Date.” If more than one share of Preferred Stock shall be surrendered for conversion at one time by the same Holder, the number of shares of Common Stock to be delivered upon conversion of such shares of Preferred Stock
shall be computed on the basis of the aggregate number of shares of Preferred Stock so surrendered. 
 (c) Immediately prior to the close of
business on the Conversion Date with respect to a conversion, a converting Holder of Preferred Stock shall be deemed to be the holder of record of the Common Stock issuable upon conversion of such Holder’s Preferred Stock notwithstanding that
the share register of the Company shall then be closed or that certificates representing such Common Stock, if any, shall not then be actually delivered to such Holder. On the date of any conversion, all rights with respect to the shares of
Preferred Stock so converted, including the rights, if any, to receive notices, will terminate, excepting only the rights of holders thereof (x) pursuant to Section 3(f) and (y) to (i) receive certificates for the number of whole
shares of Common Stock, if any, into which such shares of Preferred Stock have been converted (with a cash payment in lieu of any fractional share of Common Stock in accordance with Section 10); and (ii) exercise the rights to which they
are thereafter entitled as holders of Common Stock, if any. 
 (d) The Conversion Rate shall be adjusted, without duplication, upon the
occurrence of any of the following events: 
  

	 	(i)	If the Company exclusively issues shares of Common Stock as a dividend or distribution on all shares of its Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be
adjusted based on the following formula: 

  
 



 

  
 14 








 
					
	 where,
  

	CR0	 	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share
combination, as the case may be;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date of such share split or share combination, as
the case may be;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split
or share combination, as the case may be; and
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend or distribution, or such share split or share combination, as the case may be.


 Any adjustment made under this Section 8(d)(i) shall become effective immediately after the close of
business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in
this Section 8(d)(i) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board determines not to pay such dividend or distribution, to the Conversion Rate that would then be in
effect if such dividend or distribution had not been declared. 
  

	 	(ii)	If the Company distributes to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period expiring not more than 60 days immediately following the announcement date
of such distribution, to purchase or subscribe for shares of its Common Stock at a price per share that is less than the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the
Trading Day immediately preceding the Ex-Date of such distribution, the Conversion Rate shall be increased based on the following formula: 

  





 

  
 15 








 
					
	 where,
  

	CR0	 	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such distribution;
			
	X	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period
ending on, and including, the Trading Day immediately preceding the Ex-Date of such distribution.


 Any increase made under this Section 8(d)(ii) shall be made successively whenever any such rights,
options or warrants are distributed and shall become effective immediately after the close of business on the Record Date for such distribution. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options
or warrants, the Conversion Rate shall be readjusted, effective as of the date of such expiration, to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased, effective as of the date the Board determines not to make such
distribution, to be the Conversion Rate that would then be in effect if such Record Date for such distribution had not occurred. If such rights, options or warrants are only exercisable upon the occurrence of certain triggering events, then the
Conversion Rate shall not be adjusted until the triggering events occur. 

  
 16 








 For purposes of this Section 8(d)(ii), in determining whether any rights, options or
warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately
preceding the Ex-Date of such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any
amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board. 
  

	 	(iii)	If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets, securities or property of the Company or rights, options or warrants to acquire its Capital Stock or other
securities, to all or substantially all holders of Common Stock, excluding (a) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 8(d)(i) or Section 8(d)(ii), (b) dividends or
distributions paid exclusively in cash as to which an adjustment was effected pursuant to (or a cash amount paid pursuant to the last paragraph of) Section 8(d)(iv) and (c) Spin-Offs as to which the provisions set forth below in this
Section 8(d)(iii) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets, securities or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed
Property”), then the Conversion Rate shall be increased based on the following formula: 

  
 



 
  

					
	 where,
  

	CR0	 	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
			
	SP0	 	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such distribution; and
			
	FMV	 	=	  	the fair market value as of the Record Date for such distribution (as determined by the Board) of the Distributed Property with respect to each outstanding share of the Common Stock.

 Any increase made under the portion of this Section 8(d)(iii) above shall become effective
immediately after the close of business on the Record Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased, effective as of the date the Board determines not to pay the distribution, to be
the Conversion Rate that would then be in effect if such distribution had not been declared. 
 Notwithstanding the foregoing, if
“FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of Preferred Stock shall receive, for each
share of Preferred Stock, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of Distributed Property that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to
the Conversion Rate (determined without regard to the Conversion Cap or Beneficial Ownership Limitation) in effect on the Record Date for the distribution. 

With respect to an adjustment pursuant to this Section 8(d)(iii) where there has been a payment of a dividend or other distribution on the
Common Stock consisting solely of shares of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company where such Capital Stock or similar equity interest is, or will be
when issued, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula: 

 
  
 



 
  

					
	 where,
  

	CR0	 	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Ex-Date for the Spin-Off;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Ex-Date for the Spin-Off;
			
	FMV	 	=	  	the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock over the 10 consecutive Trading Day period immediately
following, and including, the Ex-Date for the Spin-Off; and



  
 18 








 
					
	MP0	 	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period immediately following, and including, the Ex-Date for the Spin-Off.


 The adjustment to the Conversion Rate under the preceding paragraph shall become effective at the close
of business on the 10th Trading Day immediately following, and including, the Ex-Date for the Spin-Off; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the 10 Trading Days following, and including,
the Ex-Date of any Spin-Off, references within the portion of this Section 8(d)(iii) related to Spin-Offs to 10 consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between
the Ex-Date of such Spin-Off and the relevant Conversion Date. 
  

	 	(iv)	If any cash dividend or distribution (not including the payment of the Special Dividend Withholding Tax) is made to all or substantially all holders of the Common Stock, excluding any consideration payable in connection
with a tender or exchange offer made by the Company or any of its Subsidiaries, the Conversion Rate shall be increased based on the following formula: 

  

 
 



 
  

					
	 where,
  

	CR0	 	=	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution;
			
	SP0	 	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend or distribution; and
			
	C	 	=	  	the amount in cash per share of Common Stock the Company distributes to all or substantially all holders of its Common Stock.



  
 19 








 Any increase pursuant to this Section 8(d)(iv) shall become effective immediately after the
close of business on the Record Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board determines not to pay or make such dividend or
distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of Preferred Stock shall receive, for each share of Preferred Stock, at the same time and upon the same terms as holders of
the Common Stock, the amount of cash that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the Record Date for such cash dividend or distribution (determined without regard to
the Conversion Cap or Beneficial Ownership Limitation). 
  

	 	(v)	If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock and the cash and value of any other consideration included in the payment per share of the
Common Stock exceeds the average of the Closing Sale Price of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant
to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 

  

 
 



 
  

					
	 where,
  

	CR0	 	=	  	the Conversion Rate in effect immediately prior to the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange
offer expires;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange
offer expires;
			
	AC	 	=	  	the aggregate value of all cash and any other consideration (as determined by the Board) paid or payable for shares of Common Stock purchased in such tender or exchange offer;



  
 20 








 
					
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such
tender or exchange offer);
			
	OS1	 	=	  	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or
exchange offer); and
			
	SP1	 	=	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires.


 The increase to the Conversion Rate under this Section 8(d)(v) shall occur at the close of business
on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the 10
Trading Days immediately following, and including, the Trading Day next succeeding the date that any such tender or exchange offer expires, references within this Section 8(d)(v) to 10 consecutive Trading Days shall be deemed to be replaced
with such lesser number of consecutive Trading Days as have elapsed between the date such tender or exchange offer expires and the relevant Conversion Date. 

In the event that the Company or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender offer or
exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Rate shall be readjusted to be such Conversion Rate that would
then be in effect if such tender offer or exchange offer had not been made. 
  

	 	(vi)	 All calculations and other determinations under this Section 8(d) shall be made by the Company and shall be made to the nearest one-ten
thousandth (1/10,000th) of a share. Notwithstanding anything herein to the contrary, no adjustment under this Section 8(d) shall be made to the Conversion Rate unless such adjustment would result in a change of at least 1% in the
Conversion Rate then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall
amount to a change of at least 1% in such Conversion Rate; provided, however, that the Company shall make such carried-forward adjustments, regardless of whether the aggregate adjustment is less than 1%, (a) on December 31 of
each calendar year, (b)



  
 21 









	 	
on the Conversion Date for any conversions of Preferred Stock, (c) upon the occurrence of a Fundamental Change and (d) in the event that the Company exercises its mandatory conversion
right pursuant to Section 9. No adjustment to the Conversion Rate shall be made if it results in a Conversion Price that is less than the par value (if any) of the Common Stock. 


 

	 	(vii)	In addition to those adjustments required by clauses (i), (ii), (iii), (iv) and (v) of this Section 8(d), and to the extent permitted by applicable law and subject to the applicable rules of the NASDAQ
Stock Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days or any longer period permitted or required by law if the increase is irrevocable during that period and the Board
determines that such increase would be in the Company’s best interest. In addition, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase
Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to any of the preceding two sentences, the Company shall mail to the Holder of
each share of Preferred Stock at its last address appearing on the stock register of the Company a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased
Conversion Rate and the period during which it will be in effect. 

  

	 	(viii)	For purposes of this Section 8(d), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make
any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 


(e) Notwithstanding anything to the contrary in Section 8(d), no adjustment to the Conversion Rate shall be made with respect to any
transaction described in Section 8(d)(i) through Section 8(d)(iv) if the Company makes provision for each Holder of the Preferred Stock to participate in such transaction, at the same time as holders of the Common Stock, without
conversion, as if such Holder held a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date or Effective Date, as the case may be, for such transaction, multiplied by the number of shares of Preferred Stock held
by such Holder (determined without regard to the Conversion Cap or Beneficial Ownership Limitation). No adjustment to the Conversion Rate shall be made with respect to any transaction described in Section 8(d)(v) if the Company makes provision
for each Holder of the Preferred Stock to participate in such transaction, at the same time as holders of the Common Stock as if such Holder held a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date or
Effective Date, as the case may be, for such transaction, multiplied by the number of shares of Preferred Stock held by such Holder (determined without regard to the Conversion Cap or Beneficial Ownership Limitation). 

  
 22 








 (f) Notwithstanding anything to the contrary herein, no adjustment to the Conversion Rate shall
be made pursuant to this Section 8 in respect of the issuance of any Excluded Securities. 
 (g) If the Company shall take a record of
the holders of its Common Stock for the purpose of entitling them to receive an extraordinary dividend or other distribution, and shall thereafter (and before the extraordinary dividend or distribution has been paid or delivered to stockholders)
legally abandon its plan to pay or deliver such extraordinary dividend or distribution, then thereafter no adjustment in the Conversion Rate then in effect shall be required by reason of the taking of such record. 

(h) Upon any increase in the Conversion Rate, the Company shall deliver to each Holder, as promptly as practicable, a certificate signed by an
authorized officer of the Company, setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated and specifying the increased Conversion Rate then in effect following such adjustment.

 (i) In the case of: 
  

	 	(i)	any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination), 


 

	 	(ii)	any consolidation, merger or combination involving the Company, 

  

	 	(iii)	any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety, or 


 

	 	(iv)	any statutory share exchange, 

 as a result of which the Common Stock is converted into, or exchanged
for, stock, other securities, other property or assets (including cash or any combination thereof) (any such transaction or event, a “Reorganization Event”), then, at and after the effective time of such Reorganization Event, the
right to convert each share of Preferred Stock shall be changed into a right to convert such share into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of
a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Reorganization Event would have owned or been entitled to receive upon such Reorganization Event (such stock, securities or other property or assets, the
“Reference Property”). If the Reorganization Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder
election), then the Reference Property into which the Preferred Stock will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an
election. The Company shall notify Holders of such weighted average as soon as practicable after such determination is made. None of the foregoing provisions shall affect the right of a Holder of Preferred Stock to convert its Preferred Stock into
shares of Common Stock as set forth in Section 8(a) prior to the effective time of such Reorganization Event. Notwithstanding Section 8(d), no adjustment to the Conversion Rate shall be made for any Reorganization Event to the extent
stock, securities or other property or assets become the Reference Property receivable upon conversion of Preferred Stock. 

  
 23 








 The Company shall provide, by amendment hereto effective upon any such Reorganization Event, for anti-dilution
and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Section 8. The provisions of this Section 8 shall apply to successive Reorganization Events. 

In this Certificate of Designations, if the Common Stock has been replaced by Reference Property as a result of any such Reorganization Event, references to
the Common Stock are intended to refer to such Reference Property. 
 (j) The Company shall at all times reserve and keep available for
issuance upon the conversion of the Preferred Stock a number of its authorized but unissued shares of Common Stock equal to the aggregate Liquidation Preference divided by the Conversion Price on the Issue Date, and shall take all action required to
increase the authorized number of shares of Common Stock if at any time there shall be insufficient unissued shares of Common Stock to permit such reservation or to permit the conversion of all Outstanding shares of Preferred Stock or the payment or
partial payment of dividends declared on Preferred Stock that are payable in Common Stock. 
 (k) For the avoidance of doubt, the Company
shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any such certificate in a name other than that of the holder of the shares of the relevant Preferred Stock and the Company
shall not be required to issue or deliver such certificate unless or until the Person or Persons requesting the issuance or delivery thereof shall have paid to the Company the amount of such tax or shall have established to the reasonable
satisfaction of the Company that such tax has been paid. 
 (l) Shares of Preferred Stock shall immediately and permanently cease to be
subject to the Conversion Cap for purposes of this Section 8 and Sections 5 and 9 upon the receipt of Shareholder Approval. For the avoidance of doubt and notwithstanding anything in the Certificate of Designations to the contrary, the
Conversion Cap shall not in any way limit the amounts to accrue or be paid as dividends. Shares of Preferred Stock not convertible as a result of the Conversion Cap shall remain Outstanding and shall become convertible by such Holder or another
Holder to the extent the Conversion Cap no longer applies. Notwithstanding the foregoing, the Conversion Cap shall have no effect on any adjustment to the Conversion Rate pursuant to this Section 8. 

(m) Notwithstanding Sections 8(d)(ii) and 8(d)(iii), if the Company has a rights plan (including the distribution of rights pursuant thereto
to all holders of the Common Stock) in effect while any shares of Preferred Stock remain Outstanding, Holders of Preferred Stock will receive, upon conversion of Preferred Stock, in addition to the Common Stock to which a Holder is entitled, a
corresponding number of rights in accordance with the rights plan. If, prior to any conversion, such rights have separated from the shares of Common Stock in accordance with the provisions of the applicable rights plan so that Holders of Preferred
Stock would not be entitled to receive any rights in respect of the Common Stock delivered upon conversion of Preferred Stock, the Conversion Rate will be adjusted at the time of separation, as if the Company had distributed


  
 24 








 
to all holders of its Common Stock, shares of Capital Stock, evidences of indebtedness, assets, securities, property, rights, options or warrants as described in Section 8(d)(iii) above,
subject to readjustment in the event of the expiration, termination or redemption of such rights. 
  

	(9)	Mandatory Conversion.  

 (a) During the period on or after the 3-year anniversary
of the Issue Date but prior to the 5-year anniversary of the Issue Date (the “First Mandatory Conversion Period”), the Company shall have the right, at its option, to give notice of its election to cause all Outstanding shares of
Preferred Stock to be automatically converted into that number of whole shares of Common Stock for each share of Preferred Stock equal to the Conversion Rate in effect on the Mandatory Conversion Date (subject to the limitations set forth in
Section 11), with cash in lieu of any fractional share pursuant to Section 10. The Company may exercise its right to cause a mandatory conversion pursuant to this Section 9(a) only if the Weighted Average Price of the Common Stock
equals or exceeds 140% (such percentage, the “First Mandatory Conversion Premium”) of the then-current Conversion Price for at least 20 Trading Days (whether or not consecutive) in a period of 30 consecutive Trading Days, including
the last Trading Day of such 30-day period, ending on, and including, the Trading Day immediately preceding the Business Day on which the Company issues a press release announcing the mandatory conversion as described in Section 9(d). 

(b) During the period on or after the 5-year anniversary of the Issue Date but prior to the 7-year anniversary of the Issue Date (the
“Second Mandatory Conversion Period”), the Company shall have the right, at its option, to give notice of its election to cause all Outstanding shares of Preferred Stock to be automatically converted into that number of whole shares
of Common Stock for each share of Preferred Stock equal to the Conversion Rate in effect on the Mandatory Conversion Date (subject to the limitations set forth in Section 11), with cash in lieu of any fractional share pursuant to
Section 10. The Company may exercise its right to cause a mandatory conversion pursuant to this Section 9 only if the Weighted Average Price of the Common Stock equals or exceeds 115% (such percentage, the “Second Mandatory
Conversion Premium”) of the then-current Conversion Price for at least 20 Trading Days (whether or not consecutive) in a period of 30 consecutive Trading Days, including the last Trading Day of such 30-day period, ending on, and including,
the Trading Day immediately preceding the Business Day on which the Company issues a press release announcing the mandatory conversion as described in Section 9(d). 

(c) On or after the 7-year anniversary of the Issue Date (the “Final Mandatory Conversion Period”), the Company shall have
the right, at its option, to give notice of its election to cause all Outstanding shares of Preferred Stock to be automatically converted into that number of whole shares of Common Stock for each share of Preferred Stock equal to the Conversion Rate
in effect on the Mandatory Conversion Date (subject to the limitations set forth in Section 11), with cash in lieu of any fractional share pursuant to Section 10. The Company may exercise its right to cause a mandatory conversion pursuant
to this Section 9(c) only if the Weighted Average Price of the Common Stock equals or exceeds the Conversion Price for at least 10 consecutive Trading Days, ending on, and including, the Trading Day immediately preceding the Business Day on
which the Company issues a press release announcing the mandatory conversion as described in Section 9(d). 

  
 25 








 (d) To exercise any mandatory conversion right described in Sections 9(a) through 9(c), the
Company must issue a press release for publication on the Dow Jones News Service or Bloomberg Business News (or if either such service is not available, another broadly disseminated news or press release service selected by the Company) prior to the
open of business on the first Trading Day following any date on which the condition described in any of Sections 9(a) through 9(c) is met, announcing such a mandatory conversion. The Company shall also give notice by mail or by publication (with
subsequent prompt notice by mail) to the Holders of the Preferred Stock (not later than three Business Days after the date of the press release) of the mandatory conversion announcing the Company’s intention to convert the Preferred Stock. The
conversion date will be a date selected by the Company (the “Mandatory Conversion Date”) and will be no fewer than 15 Trading Days, nor more than 20 Trading Days, after the date on which the Company issues the press release
described in this Section 9(d). Upon conversion of any Preferred Stock pursuant to this Section 9, the Company shall deliver to the applicable Holder the applicable number of shares of Common Stock, together with any applicable cash
payment in lieu of any fractional share of Common Stock, on the third Business Day immediately following the relevant Mandatory Conversion Date. 

(e) In addition to any information required by applicable law or regulation, the press release and notice of a mandatory conversion described
in Section 9 shall state, as appropriate: (i) the Mandatory Conversion Date; (ii) the number of shares of Common Stock to be issued upon conversion of each share of Preferred Stock; and (iii) that dividends on the Preferred Stock
to be converted will cease to accrue on the Mandatory Conversion Date. 
 (f) On and after the Mandatory Conversion Date, dividends shall
cease to accrue on the Preferred Stock called for a mandatory conversion pursuant to Section 9 and all rights of Holders of such Preferred Stock shall terminate except for the right to receive the whole shares of Common Stock issuable upon
conversion thereof with a cash payment in lieu of any fractional share of Common Stock in accordance with Section 10. The full amount of any dividend payment with respect to the Preferred Stock called for a mandatory conversion pursuant to
Section 9 on a date during the period beginning at the close of business on any Dividend Record Date and ending on the close of business on the corresponding Dividend Payment Date shall be payable on such Dividend Payment Date to the record
holder of such share at the close of business on such Dividend Record Date if such share has been converted after such Dividend Record Date and prior to such Dividend Payment Date. Except as provided in the immediately preceding sentence with
respect to a mandatory conversion pursuant to Section 9, no payment or adjustment shall be made upon conversion of Preferred Stock for dividends with respect to the Common Stock issued upon such conversion thereof. 

(g) Notwithstanding anything to the contrary in this Section 9, prior to the receipt of Shareholder Approval, shares of Preferred Stock
shall not be convertible pursuant to Sections 9(a), (b) or (c) in the aggregate into more than the Conversion Cap. 
 (10) No
Fractional Shares. No fractional shares of Common Stock or securities representing fractional shares of Common Stock shall be delivered upon conversion, whether voluntary or mandatory, of the Preferred Stock. Instead, the Company will make a
cash payment to each Holder that would otherwise be entitled to a fractional share based on the Closing Sale Price of the Common Stock on the relevant Conversion Date; provided, however, that the Company may round such fractional share
up to the next highest whole number of shares in lieu of making such cash payment. 

  
 26 









	(11)	Beneficial Ownership Limitation; Certain Other Transfer Restrictions. 

 (a)
Notwithstanding anything herein to the contrary, the Company shall not effect any conversion of the Preferred Stock, and a Holder shall not have the right to convert any portion of the Preferred Stock, in each case to the extent that, after giving
effect to such conversion, such Holder would beneficially own in excess of the Beneficial Ownership Limitation. For purposes of this Section 11(a), beneficial ownership of a Holder shall be calculated in accordance with Section 16(a) and
(b) of the Exchange Act and the rules and regulations promulgated thereunder for purposes of determining whether such Holder is subject to the reporting and liability provisions of Section 16(a) and 16(b) of the Exchange Act. For purposes
of complying with this Section 11(a), the Company shall be entitled to conclusively rely on the information set forth in any Holder’s Notice of Conversion, and each Holder delivering a Notice of Conversion shall be deemed to represent to
the Company that such Notice of Conversion does not violate the restrictions set forth in this paragraph, and the Company shall have no obligation to verify or confirm the accuracy of such representation. Upon the written or oral request of a
Holder, the Company shall, within two Trading Days, confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. By written notice to the Company, a Holder may from time to time increase or decrease the
Beneficial Ownership Limitation applicable solely to such Holder to any other percentage; provided that any such increase or decrease will not be effective until the sixty-fifth (65th) day after such notice is delivered to the Company. The
express purpose of this Section 11 is to preclude any Holder’s ownership of any shares of Preferred Stock from causing such Holder to become subject to the reporting and liability provisions of Section 16(a) and 16(b) of the Exchange
Act, including pursuant to Rule 16a-2 promulgated by the Commission, and this Section 11 shall be interpreted according to such express purpose. Solely for purposes of this Section 11(a), the term “Holder” shall include all
persons whose beneficial ownership of the Common Stock is aggregated pursuant to Section 13(d)(3) of the Exchange Act or Rule 13d-5 thereunder. 

(b) Notwithstanding anything contained herein to the contrary, no Preferred Stock may be owned by or transferred to any Holder or beneficial
owner that is not a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder, and any transfer made or effected in
violation of this Section 11(b) shall be void ab initio. 
 (c) Notwithstanding anything contained herein to the contrary, prior
to receipt of Shareholder Approval conversion of the Preferred Stock shall at all times be limited by the Conversion Cap. 
 (12) Transfer
Agent and Registrar. The duly appointed transfer agent (the “Transfer Agent”) and Registrar (the “Registrar”) for the Preferred Stock shall be Continental Stock Transfer & Trust Company. The Company
may, in its sole discretion, remove the Transfer Agent in accordance with the agreement between the Company and the Transfer Agent; provided that the Company shall appoint a successor transfer agent who shall accept such appointment prior to the
effectiveness of such removal. For the avoidance of doubt, the Company shall notify the Registrar in writing upon the Company’s or any of its Affiliates’ purchases or sales of Preferred Stock. 

  
 27 









	(13)	Certificates; Restrictions on Transfer. 

 (a) The Company shall, upon written
request of a Holder, issue certificates in definitive form representing the shares of Preferred Stock held by such Holder. Every share of Preferred Stock that bears or is required under this Section 13(a) to bear the legend set forth in
Section 13(b) (together with any Common Stock issued upon conversion of the Preferred Stock that is required to bear the legend set forth in Section 13(b), collectively “Restricted Securities”) shall be subject to the
restrictions on transfer set forth in Section 11(b) and this Section 13(a) (including the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the
Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 13(a) and in Section 13(b), the term “transfer” encompasses any
sale, pledge, transfer or other disposition whatsoever of any Restricted Security. 
 Until the later of (i) the date on which such
shares of Preferred Stock may be transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or sold pursuant to the exemption
from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing with written notice thereof to the Transfer Agent), and (ii) such later date, if any,
as may be required by applicable law (the “Resale Restriction Termination Date”), any certificate evidencing such Preferred Stock (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if
any, issued upon conversion thereof, which shall bear the legend set forth in Section 13(b), if applicable) shall bear a legend in substantially the following form: 

THIS SHARE OF PREFERRED STOCK AND THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SHARE OF PREFERRED STOCK HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS SHARE OF PREFERRED STOCK NOR THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SHARE OF PREFERRED STOCK NOR ANY INTEREST OR PARTICIPATION
HEREIN OR THEREIN MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING: 
 BY ITS ACQUISITION
HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER: 
  

	 	1.	REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH
RESPECT TO EACH SUCH ACCOUNT, AND 

  

	 	2.	 AGREES FOR THE BENEFIT OF BLUE BIRD CORPORATION (FORMERLY KNOWN AS HENNESSY CAPITAL ACQUISITION CORP.) (THE “COMPANY”) THAT IT WILL NOT
OFFER, SELL, PLEDGE OR OTHERWISE 



  
 28 









	 	
TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR OR SUCH OTHER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR
ANY SUCCESSOR PROVISION THERETO AFTER THE LAST DATE OF INITIAL ISSUANCE HEREOF, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT: 


 

	 	(A)	TO THE COMPANY OR ANY OF ITS SUBSIDIARIES, OR 

  

	 	(B)	PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR 

  

	 	(C)	TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR 

  

	 	(D)	PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 


PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT RESERVE THE RIGHT TO
REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO
REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. 
  

	 	3.	ACKNOWLEDGES THAT NO PREFERRED STOCK MAY BE OWNED BY OR TRANSFERRED TO ANY HOLDER OR BENEFICIAL OWNER THAT IS NOT A “UNITED STATES PERSON” WITHIN THE MEANING OF SECTION 7701(A)(30) OF THE INTERNAL REVENUE
CODE OF 1986, AS AMENDED, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER, AND ANY TRANSFER MADE OR EFFECTED IN VIOLATION OF THIS REQUIREMENT SHALL BE VOID AB INITIO. 


No transfer of any Preferred Stock prior to the Resale Restriction Termination Date will be registered by the Registrar (and shall not be
effective) unless the applicable box on the Form of Assignment and Transfer attached hereto as Exhibit B has been checked (it being understood that the checking of such box shall not substitute for satisfaction of any other applicable
transfer restrictions).

agency of the Company maintained for such purpose in The City of New York and at any other office or agency maintained by the Company for such purpose. Payments of cash shall be payable by United States dollar check drawn on, or wire transfer

	(15)	Other Provisions. 

 (a) With respect to any notice to a Holder of shares of
Preferred Stock required to be provided hereunder, neither failure to mail such notice, nor any defect therein or in the mailing thereof, to any particular Holder shall affect the sufficiency of the notice or the validity of the proceedings referred

such action. Any notice which was mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Holder receives the notice.

exchanged or converted, shall (upon compliance with any applicable provisions of the laws of Delaware) have the status of authorized but unissued shares of preferred stock of the Company undesignated as to series and may be designated or

(c) The shares of Preferred Stock shall be issuable only in whole shares. 

(d) If any applicable law requires the deduction or withholding of any tax from any payment or deemed dividend to a Holder on its Preferred
Stock, the Company or an applicable withholding agent may withhold such tax on cash dividends, shares of Preferred Stock, Common Stock or sale proceeds paid, subsequently paid or credited with respect to such Holder or his successors and assigns.
