THE WARRANTS 

Section 3.01. Form and Dating; Legends. The Warrants will be categorized as Series B Warrants and will be issuable
only in book-entry form with terms and provisions contained in the form of the Warrants attached as Exhibit A (the “Form Certificate”), which terms and provisions are hereby expressly made a part of this Agreement. The Warrants may

	 	(a)	 Except as otherwise provided in Section 3.01(b) or Section 3.09, each Warrant will bear the
Restricted Legend. 

  
 6 

 (b) If the Company determines (upon the advice of counsel and such other
certifications and evidence as the Company may reasonably require) that a Warrant is eligible for resale pursuant to Rule 144 under the Securities Act (or a successor provision) without the need to satisfy current information or other requirements
therein and that the Restricted Legend is no longer necessary or appropriate in order to ensure that subsequent transfers of the Warrant are effected in compliance with the Securities Act, the Company may instruct the Warrant Agent in writing to
remove the Restricted Legend from such Warrant, and the Warrant Agent will comply with such instruction. 
 (c) By its
acceptance of any Warrant bearing the Restricted Legend, each Holder thereof and each owner of a beneficial interest therein acknowledges the restrictions on transfer of such Warrant set forth in this Agreement and in the Restricted Legend and
agrees that it will transfer such Warrant only in accordance with this Agreement and such legend. 
 Section 3.02.
[Reserved] 
 Section 3.03. [Reserved] 

Section 3.04. [Reserved] 

Section 3.05. Outstanding Warrants. The Register shall show at any time the number of Warrants outstanding, which
shall be all Warrants that have not been canceled by the Warrant Agent or Company or instructed to the Warrant Agent for cancellation, or exercised by the Holder thereof. 

Section 3.06. Cancellation. Notwithstanding any Warrants cancelled in accordance with Section 4.01, the
Company will promptly instruct the Warrant Agent for cancellation any Warrants which the Company may have acquired in any manner whatsoever. Certification of the cancellation of all canceled Warrants shall be delivered to the Company upon written
request. The Company may not issue new Warrants to replace Warrants that have been exercised or delivered to the Warrant Agent for cancellation. 

Section 3.07. CUSIP Numbers. The Company in issuing the Warrants shall obtain and use “CUSIP” numbers
for the Warrants and the Warrant Agent will use such CUSIP numbers in notices as a convenience to Holders, with any such notice stating that no representation is made as to the correctness of such numbers either as printed on the Warrants or as
contained in any notice to any Holder. The Company will promptly notify the Warrant Agent and Holders in writing of any change in such CUSIP numbers. 

Section 3.08. Registration and Transfer. The Company shall cause the Warrant Agent to maintain a register (the
“Register”) for registering original issuance and transfer of the Warrants. Upon the initial issuance of the Warrants in book entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective Holders
thereof in such denomination and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. 

  
 7 

 (a) Subject to Section 3.09 hereof, a Holder may transfer a Warrant to
another Person by presenting to the Warrant Agent a written request therefor stating the name of the proposed transferee, accompanied by any certification, opinion or other document required by this Agreement. The Warrant Agent will promptly
register any transfer that meets the requirements of this Section 3.08 by noting the same in the Register maintained by the Warrant Agent for such purpose; provided that no transfer will be effective until it is registered in the
Register. Prior to the registration of any transfer, the Company, the Warrant Agent and their agents will treat the Person in whose name the Warrant is registered as the owner and Holder thereof for all purposes, and will not be affected by notice
to the contrary. 
 All Warrants issued upon transfer shall be duly authorized and entitled to the benefits of this
Agreement. 
 No service charge will be imposed solely in connection with any transfer of any Warrant, but the Company may
require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith. 

A party requesting transfer of Warrants or other securities must provide any evidence of authority that may be required by the
Warrant Agent, including a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association. 

(b) Subject to compliance with Section 3.09(b), if a Warrant is transferred, the transfer of such ownership shall be
effected through the Register maintained by the Warrant Agent. 
 Section 3.09. Restrictions on Transfer. The
transfer of any Warrant may only be made in accordance with this Section 3.09 and Section 3.08; provided that no such transfer shall be made to an Industry Competitor. The Warrant Agent shall refuse to register any requested
transfer that does not comply with the immediately preceding sentence; however, unless and until the Company provides the Warrant Agent with written notice that a proposed transferee is an Industry Competitor, the Warrant Agent shall have no
obligation under this Agreement to confirm or verify whether a proposed transferee is an Industry Competitor. Subject to Section 3.09(a), the Person requesting the transfer must deliver or cause to be delivered to the Warrant Agent a duly
completed Rule 144A Certificate or Accredited Investor Certificate and such other certifications and evidence as the Company may reasonably require in order to determine that the proposed transfer or exchange is being made in compliance with this
Section 3.09 and the applicable provisions of the Securities Act and any applicable securities laws of any state of the United States. 

(a) No Rule 144A Certificate, Accredited Investor Certificate or other certification and evidence is required in connection
with any transfer of any Warrant (or a beneficial interest therein) after such Warrant is eligible for resale pursuant to Rule 144 under the Securities Act (or a successor provision) without the need to satisfy current information or other
requirements therein; provided that the Company and the Warrant Agent may require from any Person requesting a transfer in reliance upon this paragraph any other reasonable certifications and evidence in connection with such resale. Any Warrant
transferred in reliance upon this paragraph will not bear the Restricted Legend. 

  
 8 

 (b) The Warrant Agent will retain electronic copies of all certificates and
other documents received in connection with the transfer of a Warrant, and the Company will have the right to inspect and make copies thereof at any reasonable time upon written notice to the Warrant Agent. 

(c) Notwithstanding anything to the contrary contained in this Agreement, the number of shares of Common Stock that may be
issued under the Warrants for any reason shall not exceed the maximum number of shares of Common Stock which the Company may issue without stockholder approval under the stockholder approval rules of the New York Stock Exchange or any other National
Securities Exchange on which the shares of Common Stock are then listed, including New York Stock Exchange Listing Rule 312.03, unless the requisite stockholder approval has been obtained. The foregoing restriction shall continue notwithstanding any
failure of the Common Stock to continue to be listed on the New York Stock Exchange or any other National Securities Exchange on which the shares of Common Stock are then listed. 

ARTICLE IV 

SEPARATION OF WARRANTS; TERMS OF WARRANTS;
EXERCISE OF WARRANTS 
 Section 4.01. Terms of Warrants; Exercise of
Warrants. 
 (a) Subject to the terms of this Agreement, a Warrant shall be exercisable, at the election of the Holder
thereof, either in full or from time to time in part during the period commencing 9:00 a.m., New York City time, on December 2, 2019 and until 5:00 p.m., New York City time, on December 2, 2029 (the “Expiration Time”), and shall
entitle the Holder thereof to receive Warrant Shares from the Company. No adjustments as to dividends will be made upon exercise of the Warrants. Each Warrant not exercised prior to the Expiration Time shall become void and all rights thereunder and
all rights in respect thereof under this Agreement shall cease as of such time. 
 (b) In order to exercise all or any of the
Warrants, the Holder thereof must deliver to the Company notice substantially in the form of the election to exercise set forth on the reverse of the Form Certificate duly filled in and signed (the “Exercise Notice”).
Following its receipt of any Exercise Notice, the Company shall promptly (and in any event, within two Business Days) provide written notice to the Warrant Agent whether (A) the Company elects (a “Net Share
Settlement Election”) to have the exercise of Warrants set forth in the Exercise Notice (the “Warrant Exercise”) net share settled pursuant to the procedures set forth in
Section 4.01(c) (a “Net Share Settlement”) or (B) the Company elects (a “Full Share Settlement Election”) to have the Warrant Exercise
settled solely in shares of Common Stock pursuant to the procedures set forth in Section 4.01(d) (a “Full Share Settlement”). If the Company shall not have provided such a notice to the Warrant Agent by
5:00 p.m., New York City time, on the second Business Day following the Company’s receipt of any such Exercise Notice, the Company will be deemed to have made a Full Share Settlement Election with respect to the Warrants to which such Exercise
Notice relates, as of such time. 

  
 9 

 (c) If the Company makes a Net Share Settlement Election pursuant to
Section 4.01(b) with respect to the Warrant Exercise, then the Warrant Exercise shall be “net share settled” whereupon Warrant will be converted into shares of Common Stock pursuant to a cashless exercise, after which the Company will
issue to the Holder the Warrant Shares equal to the result obtained by (i) subtracting B from A, (ii) dividing the result by A, and (iii) multiplying the difference by C as set forth in the following equation: 

X = ((A - B)/A) x C 

where: 
  

					
		 	 X =
	  	 the Warrant Shares issuable upon exercise pursuant to this paragraph (c).

			
		 	 A =
	  	 the Market Value of a share of Common Stock as of the date on which the Holder delivers the applicable Exercise
Notice.

			
		 	 B =
	  	 the Exercise Price per share of Common Stock.

			
		 	 C =
	  	 with respect to the Warrant then being exercised, the number of shares of Common Stock for which such Warrant is
exercisable, prior to the Net Share Settlement procedures pursuant to this paragraph (c).

 If the foregoing calculation results in a negative number, then no shares of Common Stock shall be issued upon
exercise pursuant to this paragraph (c). The Company shall calculate and transmit to the Warrant Agent, and the Warrant Agent shall have no obligation under this Agreement to make, any calculations in respect of any Net Share Settlements. The number
of Warrant Shares to be issued on such Net Share Settlement will be determined by the Company (with written notice thereof to the Warrant Agent) using the formula set forth in this Section 4.01(c). The Warrant Agent shall have no duty or
obligation to investigate or confirm whether the Company’s determination of the number of Warrant Shares to be issued on such exercise, pursuant to this Section 4.01(c) is accurate or correct. 

(d) If a Full Share Settlement Election is made pursuant to Section 4.01(b) with respect to a Warrant Exercise, then
within one Business Day following the date of the Full Share Settlement Election, the Holder shall deliver payment to the Company of an amount equal to the Exercise Price multiplied by the number of Warrant Shares issuable as to which the Warrant
was so exercised in cash or via wire transfer of immediately available funds, provided that the failure to deliver payment shall not prejudice the Holder’s right to receive the number of shares of Common Stock into which the Warrant is
convertible upon payment of the Exercise Price. 

  

 (e) Within one Business Day following the date the Exercise Notice is delivered to the
Company, the Holder shall deliver payment to the Company of an amount equal to the Exercise Price multiplied by the number of Warrant Shares issuable as to which the Warrant was so exercised in cash or via wire transfer of immediately available
funds. 
 (f) Upon compliance with the provisions set forth above, the Company shall promptly deliver or cause to be delivered, to or upon
the written order of the Holder and in such name or names as the Holder may designate, a certificate or certificates for the number of whole Warrant Shares issuable upon the exercise of such Warrants or other securities or property to which such
Holder is entitled, together with cash in lieu of fractional shares as provided in Section 6.02. Such certificate or certificates or other securities or property shall be deemed to have been issued, and any person so designated to be named
therein shall be deemed to have become a holder of record of such Warrant Shares or other securities or property, as of the date of the delivery of the Exercise Notice, notwithstanding that the stock transfer books of the Company shall then be
closed or the certificates or other securities or property have not been delivered. If applicable, the Company shall provide to Computershare an initial funding of one thousand dollars ($1,000) for the purpose of issuing cash in lieu of fractional
shares. From time to time thereafter, Computershare may request additional funding to cover fractional payments. Computershare shall have no obligation to make fractional payments unless the Company shall have provided the necessary funds to pay in
full all amounts due and payable with respect thereto. 
 (g) The Warrant Agent shall keep copies of this Agreement and any notices given or
received hereunder available for inspection by the Holders during normal business hours at its office upon reasonable notice to the Warrant Agent by the Holders. The Company shall supply the Warrant Agent from time to time with such numbers of
copies of this Agreement as the Warrant Agent may reasonably request. 
 (h) Certificates, if any, representing Warrant Shares shall bear a
Restricted Legend (with all references to Warrants therein replaced by references to Common Stock, and with such changes thereto as the Company may deem appropriate) if (i) the Warrants for which they were issued carried a Restricted Legend or
(ii) the Warrant Shares are issued in a transaction exempt from registration under the Securities Act (other than the exemption provided by Section 3(a)(9) of the Securities Act), in each case until and unless the circumstances set forth
in Section 3.01(b) apply to such Warrant Shares, and any transfers thereof shall comply with the Restricted Legend. 
 (i)
Notwithstanding anything to the contrary herein, (i) unless otherwise agreed by the Company and the Holder, the Warrant Shares shall be in uncertificated, book-entry form as permitted by the by-laws of
the Company and the laws of the Republic of Panama, and (ii) delivery of Warrant Shares upon exercise of a Warrant shall be made to the applicable Holder through the facilities of The Depository Trust Company as directed by such Holder unless
such Holder shall otherwise instruct. 

  
 11 

 Section 4.02. Conditional Exercise. Notwithstanding any other
provision hereof, if an exercise of any portion of a Warrant is to be made in connection with a public offering or a sale of the Company (pursuant to a merger, sale of stock or otherwise), such exercise may at the election of the Holder be
conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction. 

Section 4.03. Opinion of Counsel. The Company shall provide one or more Opinions of Counsel prior to the issuance
of Warrants to set up a reserve of warrants and related Common Stock. The opinions shall, taken together, state that all warrants or Common Stock, as applicable, are: registered under the Securities Act, as amended, or are exempt from such
registration, and all appropriate state securities law filings have been made with respect to the warrants or shares; and validly issued, fully paid and non-assessable. 

Section 4.04. Cost Basis Information. 

(a) In the event of a Full Share Settlement, the Company shall instruct the Warrant Agent to record cost basis for newly issued
Warrant Shares issued pursuant to a Full Share Settlement in a manner reasonably determined by the Company to be subsequently communicated by the Company to the Warrant Agent. 

(b) In the event of a Net Share Settlement, the Company shall provide cost basis for Warrant Shares issued pursuant to a Net
Share Settlement at the time the Company confirms the number of Warrant Shares issuable in connection with the Net Share Settlement to the Warrant Agent. 

ARTICLE V 

COVENANTS OF THE COMPANY 

Section 5.01. Maintenance of Office or Agency. The Company will maintain in the United States an office or agency
where Warrants may be surrendered for registration of transfer or exchange or for presentation for exercise. The Company hereby initially designates the Corporate Trust Office of the Warrant Agent as such office of the Company. The Company will give
prompt written notice to the Warrant Agent of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Warrant Agent with the
address thereof, such presentations and surrenders may be made or served to the Warrant Agent. 
 The Company may also from
time to time designate one or more other offices or agencies where the Warrants may be surrendered or presented for any of such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Warrant
Agent of any such designation or rescission and of any change in the location of any such other office or agency. 

  
 12 

 Section 5.02. Payment of Taxes. The Company will pay all
documentary, stamp or similar issue or transfer taxes in respect of the issuance or delivery of Warrant Shares upon the exercise of Warrants; provided that the exercising Holder shall be required to pay any tax or taxes which may be payable
in respect of any transfer involved in the issue of any Warrants or any Warrant Shares in a name other than that of the registered holder of a Warrant surrendered upon exercise, and the Company and the Warrant Agent shall not be required to issue
such Warrant unless or until the exercising Holder shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company and the Warrant Agent that such tax has been paid. 

Section 5.03. Rule 144A(d)(4) Information. For so long as any of the Warrants or Warrant Shares remain outstanding
and constitute “restricted securities” under Rule 144, the Company will make available upon request to any prospective purchaser of the Warrants or Warrant Shares or beneficial owner of Warrants or Warrants Shares in connection with any
sale thereof the information required by Rule 144A(d)(4) under the Securities Act; provided that such information shall be deemed conclusively to be made available pursuant to this Section 5.03 if the Company has filed such information
with the Commission via its Electronic Data Gathering, Analysis and Retrieval System (or any successor electronic system maintained by the Commission) and such information is publicly available on such system. 

Section 5.04. Reservation of Warrant Shares. (a) The Company will reserve and keep available for issuance and
delivery such number of its authorized but unissued shares of Common Stock or other securities of the Company as will from time to time be sufficient to permit the exercise in full of all outstanding Warrants, which shares or securities will, when
issued, be free and clear of all liens, security interests, charges and other encumbrances and free and clear of all preemptive rights. 

(b) The Company will authorize and direct the transfer agent for the Common Stock (the “Transfer Agent”) and
every subsequent transfer agent for any securities of the Company issuable upon the exercise of the Warrants to reserve such number of authorized securities as shall be required for such purpose. The Company will supply such Transfer Agent with duly
executed certificates for such purposes and will provide or otherwise make available any cash which may be payable as provided in Sections 4.01(d) and 6.02. The Company will furnish such Transfer Agent a copy of all notices of adjustments, and
certificates related thereto, transmitted to each Holder pursuant to Section 6.01(d). 
 Section 5.05.
Listing. The Company shall use commercially reasonable efforts to cause the Warrant Shares, immediately upon such exercise, to be listed on the New York Stock Exchange or the principal securities exchange on which shares of Common Stock or
other securities constituting Warrant Shares are listed at the time of such exercise. The Company shall take all such actions as may be necessary to ensure that all Warrant Shares are issued without violation by the Company of any applicable law or
governmental regulation or any requirements of any securities exchange upon which shares of Common Stock or other securities constituting Warrant Shares may be listed at the time of such exercise. 

  
 13 

 Section 5.06. HSR Act. If the Company or any Holder of Warrants
determines, after consultation with the other, that a filing is required pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), solely in connection with the exercise of Warrants hereunder,
then the Company, on the one hand, and such Holder of Warrants, on the other hand, shall as promptly as practicable make, or cause to be made, all filings and submissions required under the HSR Act with respect to the exercise of such Warrants and
use their commercially reasonable efforts to obtain, or cause to be obtained, consent in respect of such filings and submissions (or the termination or expiration of the applicable waiting period, as applicable) as soon as possible thereafter. 

ARTICLE VI 

ADJUSTMENT OF NUMBER OF 

WARRANT SHARES ISSUABLE 

Section 6.01. Adjustment to Number of Warrant Shares. The number of Warrant Shares issuable upon the exercise of
each Warrant (the “Exercise Ratio”) is subject to adjustment from time to time upon the occurrence of the events enumerated in this Section 6.01. 

In the event that, at any time as a result of the provisions of this Section 6.01, the Holders of the Warrants shall
become entitled upon subsequent exercise to receive any shares of Capital Stock of the Company other than Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall thereafter be subject to adjustment from time
to time in a manner and on terms as nearly equivalent as practicable to the provisions contained herein. 
 (a)
Adjustments for Change in Capital Stock. 
 (i) If the Company pays a dividend (or other distribution)
in shares of Common Stock to all holders of the Common Stock, then the Exercise Ratio in effect immediately following the record date for such dividend (or distribution) shall be multiplied by the following fraction: 

 

					
	

	 	
		
		 	where
			
	    	 	OS0 =	 	the number of shares of Common Stock outstanding immediately prior to the record date for such dividend or distribution; and
			
		 	 OS1 =
	 	the sum of (A) the number of shares of Common Stock outstanding immediately prior to the record date for such dividend or distribution and (B) the total number of shares of Common Stock constituting such
dividend.

  
 14 

 (ii) If the Company issues to all holders of shares of the
Common Stock rights, options or warrants entitling them, for a period of not more than 60 days from the date of issuance of such rights, options or warrants, to subscribe for or purchase shares of Common Stock at less than the Market Value
determined on the Ex-Date for such issuance, then the Exercise Ratio in effect immediately following the close of business on the Ex-Date for such issuance shall be
multiplied by the following fraction: 
  

					
	

	 	
		
		 	where
			
	    	 	OS0 =	 	the number of shares of Common Stock outstanding at the close of business on the record date for such issuance;
			
		 	   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 Market Value determined as of the last trading day preceding the date of the agreement on pricing
such rights, options or warrants.

 To the extent that such rights, options or warrants are not exercised prior to their
expiration or shares of Common Stock are otherwise not delivered pursuant to such rights or warrants upon the exercise of such rights or warrants, the number of Warrant Shares shall be readjusted to the number of Warrant Shares that would have then
been in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are only
exercisable upon the occurrence of certain triggering events, then the number of Warrant Shares shall not be adjusted until such triggering events occur. In determining the aggregate offering price payable for such shares of Common Stock, the
conversion agent shall take into account any consideration received for such rights, options or warrants and the value of such consideration (if other than cash, to be determined by the Board of Directors). 

(iii) If the Company subdivides, combines or reclassifies the shares of Common Stock into a greater or lesser
number of shares of Common Stock, then the Exercise Ratio in effect immediately following the effective date of such share subdivision, combination or reclassification shall be multiplied by the following fraction: 

  
 15 

					
	

		 	 where

			
	     
	 	 OS0 =
	 	 the number of shares of Common Stock outstanding immediately prior to the effective date of such
share subdivision, combination or reclassification; and

			
		 	OS1 =	 	the number of shares of Common Stock outstanding immediately after the opening of business on the effective date of such share subdivision, combination or reclassification (after giving effect thereto).

 (iv) If the Company distributes to all holders of shares of Common Stock
evidences of indebtedness, shares of Capital Stock (other than Common Stock) or other assets (including cash or securities, but excluding any dividend or distribution referred to in clause (i) above; any rights or warrants referred to in clause
(ii) above; and any dividend of shares of Capital Stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in the case of certain spin-off
transactions as described below), then the Exercise Ratio in effect immediately following the close of business on the record date for such distribution shall be multiplied by the following fraction: 

 

					
	

		
		 	 where

			
	         
	 	    SP0 =
	 	 the Closing Sale Price per share of Common Stock on the Trading Day immediately preceding the Ex-Date; and

			
		 	FMV =	 	the fair market value of the portion of the distribution applicable to one share of Common Stock on the Trading Day immediately preceding the Ex-Date as determined by the Board of
Directors.

 In a spin-off, where the Company makes a distribution
to all holders of shares of Common Stock consisting of Capital Stock of any class or series, or similar equity interests of, or relating to, a subsidiary or other business unit the Exercise Ratio shall be adjusted on the fourteenth Trading Day after
the effective date of the distribution by multiplying the Exercise Ratio in effect immediately prior to such fourteenth Trading Day by the following fraction: 
  

					
	

		
		 	 where

			
	         
	 	 MP0 =
	 	 the average of the Closing Sale Price of the Common Stock over each of the first 10 Trading Days
commencing on and including the fifth Trading Day following the effective date of such distribution; and

			
		 	MPS =	 	the average of the closing sale price of the Capital Stock or equity interests representing the portion of the distribution applicable to one share of Common Stock over each of the first 10 Trading Days commencing on

  
 16 

	
	 and including the fifth Trading Day following the effective date of such distribution, or, as reported in the principal
securities exchange or quotation system or market on which such shares are traded, or if not traded on a national or regional securities exchange or over-the-counter
market, the fair market value of the Capital Stock or equity interests representing the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors.

 In the event that such distribution described in this clause (iv) is not so made, the
Exercise Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such dividend or distribution, to the Exercise Price that would then be in effect if such dividend distribution had not
been declared. 
 (v) In case the Company effects a Pro Rata Repurchase of Common Stock, then the Exercise
Ratio shall be adjusted to the price determined by multiplying the Exercise Ratio in effect immediately prior to the effective date of such Pro Rata Repurchase by a fraction of which he denominator shall be the product of (x) the number of
shares of Common Stock outstanding immediately prior to such Pro Rata Repurchase minus the number of shares of Common Stock so repurchased and (y) the Market Value per share of Common Stock on the trading day immediately preceding the first
public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase, and of which the numerator shall be (i) the product of (x) the number of shares of Common Stock outstanding immediately before
such Pro Rata Repurchase and (y) the Market Value of a share of Common Stock on the trading day immediately preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase, minus
(ii) the aggregate purchase price of the Pro Rata Repurchase. 
 (vi) In case of any Business
Combination or reclassification of Common Stock (other than a reclassification of Common Stock referred to in Section 6.01(a)(iii)), the Holder’s right to receive Warrant Shares upon exercise of the Warrants shall be converted into the
right to exercise the Warrants to acquire the number of shares of stock or other securities or property (including cash) that the Common Stock issuable (at the time of such Business Combination or reclassification) upon exercise of each Warrant
immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification; and in any such case, if necessary, the provisions set forth herein with
respect to the rights and interests thereafter of the Holder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to the Holder’s right to exercise each Warrant in exchange for any shares of stock or other
securities or property pursuant to this Section 6.01(a)(vi). In determining the kind and amount of stock, securities or the property receivable upon exercise of each Warrant following the consummation of such Business Combination, if the
holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the Holder shall have the right to make a similar election (including being subject to similar
proration constraints) upon exercise of each Warrant with respect to the number of shares of stock or other securities or property that the Holder will receive upon exercise of a Warrant. 

  
 17 

 (vii) Notwithstanding anything herein to the contrary, no
adjustment under this Section 6.01 need be made to the Exercise Ratio unless such adjustment would require a cumulative increase or decrease of at least 2.0% of the Exercise Ratio 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 cumulative increase or decrease of at least 2.0% of such Exercise
Ratio. 
 (viii) The Company reserves the right to make such increase in the Exercise Ratio in addition to
those required in the foregoing provisions as it considers advisable in order that any event treated for Federal income tax purposes as a dividend or distribution of stock or stock rights will result in less or no tax to the recipients. In the event
the Company elects to make such an increase in the Exercise Price, the Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder
if and to the extent that such laws and regulations are applicable in connection with the increase of the Exercise Price. 

(ix) Notwithstanding any other provisions of this Section 6.01(a), rights or warrants distributed by the
Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a
specified event or events (“Trigger Event”): are deemed to be transferred with such shares of Common Stock; are not exercisable; and are also issued in respect of future issuances of Common Stock, shall be deemed not to have
been distributed for purposes of this Section 6.01(a) (and no adjustment to the Exercise Ratio under this Section 6.01(a) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is required) to the Exercise Ratio shall be made under Section 6.01(a)(ii). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or
any Trigger Event or other event with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exercise Ratio under this Section 6.01(a) was made, in the case of any such rights or
warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Exercise Ratio shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may
be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants),
made to all holders of Common Stock as of the date of such 

  
 18 

 
redemption or repurchase, and in the case of such rights or warrants that shall have expired or been terminated without exercise thereof, the Exercise Ratio shall be readjusted as if such expired
or terminated rights and warrants had not been issued. To the extent that the Company has a rights plan or agreement in effect upon exercise of the Warrants, which rights plan provides for rights or warrants of the type described in this clause,
then upon exercise of the Warrants, the Holder will receive, in addition to the Common Stock to which he is entitled, a corresponding number of rights in accordance with the rights plan, unless a Trigger Event has occurred and the adjustments to the
Exercise Ratio with respect thereto have been made in accordance with the foregoing. In lieu of any such adjustment, the Company may amend such applicable stockholder rights plan or agreement to provide that upon exercise of the Warrants, the
Holders will receive, in addition to the Common Stock issuable upon such exercise, the rights that would have attached to such Common Stock if the Trigger Event had not occurred under such applicable stockholder rights plan or agreement. 

(b) Notwithstanding anything to the contrary in this Section 6.01, no adjustment to the Exercise Ratio shall be made with
respect to any distribution or other transaction if Holders are entitled to participate in such distribution or transaction as if they held a number of shares of Common Stock issuable upon exercise of the Warrants immediately prior to such event,
without having to exercise their Warrants. 
 (c) If the Company shall take a record of the holders of its Common Stock for
the purpose of entitling them to receive a dividend or other distribution, and shall thereafter (and before the dividend or distribution has been paid or delivered to stockholders) abandon its plan to pay or deliver such dividend or distribution,
then thereafter no adjustment in the Exercise Price then in effect shall be required by reason of the taking of such record. 

(d) Notice of Adjustment. Whenever the Exercise Price is adjusted, the Company shall provide the notices required by
Section 6.03. 
 (e) Company Determination Final. Notwithstanding anything to the contrary herein, whenever the
Board of Directors is permitted or required to determine Market Value or fair market value, such determination shall be made in good faith and, absent manifest error, shall be final and binding on the Holders and the Warrant Agent. 

(f) When Issuance or Payment May Be Deferred. In any case in which this Section 6.01 shall require that an
adjustment in the Exercise Ratio be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event issuing to the Holder of any Warrant exercised after such record date the Warrant Shares
and other Capital Stock of the Company, if any, issuable upon such exercise over and above the Warrant Shares and other Capital Stock of the Company, if any, issuable upon such exercise on the basis of the Exercise Ratio and paying to such Holder
any amount in cash in lieu of a fractional share pursuant to Section 6.02; provided that the Company shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder’s right to receive such additional
Warrant Shares, other Capital Stock and cash upon the occurrence of the event requiring such adjustment. 

  
 19 

 (g) Form of Warrants. Irrespective of any adjustments in the Exercise Price or the
number or kind of shares purchasable upon the exercise of the Warrants, Warrants theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the Warrants initially issuable pursuant to this
Agreement. 
 Section 6.02. Fractional Interests. The Company shall not be required to issue fractional Warrant
Shares or scrip representing fractional shares on the exercise of Warrants. If more than one Warrant shall be presented for exercise in full at the same time by the same Holder, the number of full Warrant Shares which shall be issuable upon the
exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares issuable on exercise of the Warrants so presented. If any fraction of a Warrant Share would, except for the provisions of this Section 6.02, be issuable
on the exercise of any Warrants (or specified portion thereof), the Company may, at its option, either pay an amount in cash equal to the current Closing Sale Price per Warrant Share, as determined on the date the Warrant is presented for exercise,
multiplied by such fraction, computed to the nearest whole U.S. cent, or round the number of Warrant Shares issued up to the nearest number of whole Warrant Shares. Whenever a payment for fractional Warrant Shares is to be made by the Warrant Agent,
the Company shall promptly prepare and deliver to the Warrant Agent a certificate setting forth in reasonable detail the facts related to such payments and the prices and formulas utilized in calculating such payments, and provide sufficient
monies to the Warrant Agent in the form of fully collected funds to make such payments. The Warrant Agent shall be fully protected in relying upon such a certificate and shall have no duty with respect to, and shall not be deemed to have knowledge
of, any payment for fractional Warrant Shares under any section of this Agreement relating to the payment of fractional Warrant Shares unless and until the Warrant Agent shall have received such a certificate and sufficient monies. The Company shall
provide an initial funding of one thousand dollars ($1,000) for the purpose of paying cash in lieu of fractional Warrant Shares. From time to time thereafter, Computershare may request additional funding to cover payments in lieu of fractional
Warrant Shares. 
 Section 6.03. Notices to Warrant Holders. 

(a) Upon any adjustment of the Exercise Price pursuant to Section 6.01, the Company shall promptly thereafter cause
to be filed with the Warrant Agent a certificate of the Chief Financial Officer of the Company setting forth the Exercise Price after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such
calculations are based and setting forth the number of Warrant Shares (or portion thereof) or other securities or property issuable after such adjustment in the Exercise Price, upon exercise of a Warrant, which certificate shall be presumed, absent
manifest error, to correctly present the matters set forth therein, and cause to be given to each of the Holders written notice of such adjustments by first-class mail, postage prepaid. Where appropriate, such notice may be given in advance and
included as a part of the notice required to be mailed under the other provisions of this Section 6.03. Until 

  
 20 

 
such certificate is received by the Warrant Agent, the Warrant Agent may presume conclusively for all purposes that no such adjustments have been made, and the Warrant Agent shall have no duty or
obligation to investigate or confirm whether any of the Company’s determinations are accurate or correct. 
 (b) In
case: 
 (i) the Company shall authorize the issuance to all holders of shares of Common Stock of rights,
options or warrants to subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; 

(ii) the Company shall authorize the distribution to all holders of shares of Common Stock of evidences of its
indebtedness or assets (other than dividends or distributions referred to in Section 6.01(a)); 
 (iii)
of any reclassification or change of Common Stock issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or a
tender offer or exchange offer for shares of Common Stock by the Company; 
 (iv) of the voluntary or
involuntary dissolution, liquidation or winding up of the Company; or 
 (v) the Company proposes to take any
action which would require an adjustment of the Exercise Price pursuant to Section 6.01; 
 then the Company shall cause to be filed
with the Warrant Agent and shall cause to be given to each of the Holders, at least 10 days prior to any applicable record date, or promptly in the case of events for which there is no record date, by first-class mail, postage prepaid, a written
notice stating (x) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such rights, options, warrants or distribution are to be determined, (y) the initial expiration date set forth in any
tender offer or exchange offer for shares of Common Stock, or (z) the date on which any such transaction is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock
shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such transaction. The failure to give the notice required by this Section 6.03 or any defect therein shall not affect the legality or validity
of any transaction, or the vote upon any action. 
 Section 6.04. No Rights as Stockholders; Limitations of
Liability. Nothing contained in this Agreement or the Warrants shall be construed as conferring upon the holders of Warrants the right to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the
election of directors of the Company or any other matter, or any rights whatsoever, including the right to receive dividends or other distributions, as stockholders of the Company, or the right to share in the assets of the Company in the event of
its liquidation, dissolution or winding up, except in respect of 

  
 21 

 
Common Stock received following exercise of Warrants or imposing any fiduciary or other duties on the Company or any of its directors or officers, all of which rights and duties are expressly
waived by the Holders. In addition, nothing contained in this Agreement or the Warrants shall be construed as imposing any liabilities on the Holder as a stockholder of the Company, whether such liabilities are asserted by the Company or by
creditors of the Company. 
 ARTICLE VII 

WARRANT AGENT 

Section 7.01. Warrant Agent. The Warrant Agent undertakes the express duties and obligations imposed by this
Agreement upon the following terms and conditions (and no duties or obligations shall be inferred), by all of which the Company and the holders of Warrants, by their acceptance thereof, shall be bound: 

(a) The statements and recitals contained herein and in the Warrants shall be taken as statements of the Company, and the
Warrant Agent assumes no responsibility and shall not be liable for the correctness of any of the same except such as describe the Warrant Agent. The Warrant Agent assumes no responsibility with respect to the distribution of the Warrants except as
herein otherwise expressly provided. 
 (b) The Warrant Agent has no duty to determine when an adjustment under Article VI
should be made, how any such adjustment should be made or what any such adjustment should be. Nor shall the Warrant Agent have any obligation hereunder to determine whether an adjustment event has occurred. The Warrant Agent makes no representation
as to the validity or value of any securities or assets issued upon exercise of Warrants. The Warrant Agent shall have no obligation under this Agreement to calculate, confirm, investigate or verify the accuracy of the correctness of, the number of
Warrant Shares issuable in connection with any exercise hereunder. 
 (c) The Warrant Agent shall not be accountable with
respect to (i) the validity, value, kind or amount of any Warrant Shares, securities or property which may be issued or delivered at any time upon the exercise of any Warrant or (ii) whether any such Warrant Shares or other securities
will, when issued, be validly issued, fully paid and nonassessable; and in each case, makes no representation with respect thereto. 

(d) The Warrant Agent shall not be responsible for any failure of the Company to comply with any of the covenants contained in
this Agreement or in the Warrants. 
 (e) The Warrant Agent may rely on, and will be held harmless, indemnified and protected
and shall incur no liability in acting or refraining from acting, upon any resolution, certificate, statement, instrument, instruction, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document from the Company with respect to any matter relating to its acting as Warrant Agent hereunder believed by it to be genuine and to have been signed or presented by the proper Person. The Warrant Agent need not
investigate any fact or matter stated in the document. The Warrant Agent, in its discretion, may make further inquiry or investigation into such facts or matters as it sees fit. The Warrant Agent shall not be held to have notice of any change of
authority of any Person, until receipt of written notice thereof from the Company. 

  
 22 

 (f) The Warrant Agent may consult with legal counsel, and the advice of such
counsel or any Opinion of Counsel will be full and complete authorization and protection to the Warrant Agent and the Warrant Agent will incur no liability for or in respect of any action taken, suffered or omitted by it hereunder in the absence of
willful misconduct, bad faith or gross negligence (each as determined by a final judgment of a court of competent jurisdiction) in reliance thereon. 

(g) The Warrant Agent may act through its attorneys and agents and will not be responsible for the misconduct or negligence of
any agent absent gross negligence, bad faith or willful misconduct (each as determined by a final judgment of a court of competent jurisdiction) in the appointment of such agent. 

(h) The Warrant Agent shall act hereunder solely as agent for the Company, and its duties shall be determined solely by the
express provisions hereof. No provision of this Agreement shall be construed to relieve the Warrant Agent from liability for its own gross negligence, bad faith or willful misconduct (each as determined by a final judgment of a court of competent
jurisdiction). 
 (i) The Warrant Agent shall not have any duty or responsibility in the case of the receipt of any written
demand from any Holder of Warrants with respect to any action or default by the Company, including any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or to make any demand upon the Company. 

(j) The Warrant Agent shall not be obligated to expend or risk its own funds or to take any action that it believes would
expose or subject it to expense or liability or to a risk of incurring expense or liability, unless it has been furnished with assurances of repayment or indemnity satisfactory to it; provided, further, that the Warrant Agent may in
any event resign pursuant to Section 7.04(i) instead of taking any such action. 
 (k) The Warrant Agent shall not be
liable or responsible for any failure of the Company to comply with any of its obligations relating to any registration statement filed with the Commission or this Agreement, including obligations under applicable regulation or law. 

(l) The Warrant Agent shall not be accountable or under any duty or responsibility for the application by the Company of the
proceeds of the issue and sale, or exercise, of the Warrants. 
 (m) The Warrant Agent shall act hereunder solely as agent
for the Company, and its duties shall be determined solely by the express provisions hereof (and no duties or obligations shall be inferred or implied). The Warrant Agent shall not assume any obligations or relationship of agency or trust with any
of the owners or holders of the Warrants. The Warrant Agent shall not be charged with knowledge or notice of any fact or circumstance not expressly set forth herein, and shall not be bound by the provisions of any other agreement or document among
the Company and the Holders except this Agreement. 

  
 23 

 (n) The Warrant Agent may rely on and be fully authorized and protected in
acting or failing to act upon any guaranty of signature by an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program”
or insurance program in addition to, or in substitution for, the foregoing; or any law, act, regulation or any interpretation of the same even though such law, act, or regulation may thereafter have been altered, changed, amended or repealed. 

(o) In the event the Warrant Agent believes any ambiguity or uncertainty exists hereunder or in any notice, instruction,
direction, request or other communication, paper or document received by the Warrant Agent hereunder, the Warrant Agent, may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to
Company, any Holder of a Warrant or any other Person for refraining from taking such action, unless the Warrant Agent receives written instructions signed by the Company which eliminates such ambiguity or uncertainty to the reasonable satisfaction
of Warrant Agent. 
 (p) The provisions of this Section 7.01, Section 7.02 and Section 7.03 will survive the
termination of this Agreement, the exercise or expiration of the Warrants and the resignation, replacement or removal of the Warrant Agent. 

Section 7.02. Compensation; Indemnity; Limitation on Liability. The Company will pay the Warrant Agent
compensation for all services rendered by it hereunder as agreed upon in writing for its services. The Company will reimburse the Warrant Agent upon request for all reasonable
out-of-pocket expenses, disbursements and advances incurred or made by the Warrant Agent in the exercise and performance of its duties hereunder, except any such
expense, disbursement or advance attributable to its gross negligence, bad faith or willful misconduct (each as determined by a final non-appealable judgment of a court of competent jurisdiction). Such
expenses shall include the reasonable compensation and expenses of the Warrant Agent’s third-party agents and outside counsel. 

(a) The Company will indemnify the Warrant Agent for, and hold it harmless against, any loss, liability, suit, action,
proceeding, damage, judgment, fine, penalty, claim, demand, settlement, costs or expense incurred (including the reasonable fees and expenses of outside legal counsel) without gross negligence, bad faith or willful misconduct (each as determined by
a final, non-appealable judgment of a court of competent jurisdiction) on the part of the Warrant Agent, for anything done or omitted to be done by the Warrant Agent in connection with the acceptance,
administration of, exercise and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly. The reasonable costs and expenses incurred in
enforcing this right of indemnification will be paid by the Company if the Warrant Agent is entitled to indemnification by the Company pursuant to this Agreement (as determined by a final, 

  
 24 

 
non-appealable judgment of a court of competent jurisdiction). The Warrant Agent shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Warrant Agent to so notify the Company shall not relieve the Company of its obligations hereunder, except to the extent the Company is prejudiced thereby. The Company need not pay for any settlement made without its
consent, which consent shall not be unreasonably withheld. 
 (b) Notwithstanding anything contained herein to the contrary,
the Warrant Agent’s aggregate liability during the term of this Agreement with respect to, or arising from or in connection with this Agreement, or from any services provided or omitted to be provided under this Agreement, whether in contract,
or in tort, or otherwise, is limited to, and shall not exceed, the amounts paid hereunder by the Company to Warrant Agent as fees and charges (but not including reimbursable expenses) during the 12 months immediately preceding the event for which
recovery from the Warrant Agent is being sought. 
 (c) Notwithstanding anything in this Agreement to the contrary, in no
event will the Warrant Agent be liable for special, punitive, indirect, incidental or consequential loss or damage of any kind whatsoever (including lost profits), even if the Warrant Agent has been advised of the likelihood of such loss or damage
and regardless of the form of action. The Warrant Agent will not be deemed to have knowledge of any event of which it was supposed to receive notice thereof hereunder, and the Warrant Agent will be fully protected and will incur no liability for
failing to take any action in connection therewith unless and until it has received such notice. 
 Section 7.03.
Individual Rights of Warrant Agent. The Warrant Agent, and any stockholder, director, officer or employee of it, may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any
transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity. 
 Section 7.04. Replacement of Warrant
Agent. (a) The Warrant Agent 
 (i) may resign and be discharged from its duties under this
Agreement at any time by not less than 30 days’ written notice to the Company (pursuant to Section 8.02), 

(ii) may be removed at any time by the Company, for any reason, by at least 30 days’ written notice to the
Warrant Agent, and 
 (iii) may be removed immediately by the Company if: the Warrant Agent is adjudged a
bankrupt or an insolvent; a receiver or other public officer takes charge of the Warrant Agent or its property; or the Warrant Agent becomes incapable of acting. 

  
 25 

 In the event the transfer agency relationship in effect between the Company and the Warrant
Agent terminates, the Warrant Agent will be deemed to have resigned automatically and be discharged from its duties under this Agreement as of the effective date of such termination. 

(b) If the Warrant Agent resigns or is removed, or if a vacancy exists in the office of Warrant Agent for any reason, the
Company will promptly appoint a successor Warrant Agent. If the successor Warrant Agent does not deliver its written acceptance within 30 days after the retiring Warrant Agent resigns or is removed, the retiring Warrant Agent, the Company or the
Holders of a majority of the outstanding Warrants may petition any court of competent jurisdiction for the appointment of a successor Warrant Agent. 

(c) Upon delivery by the successor Warrant Agent of a written acceptance of its appointment to the retiring Warrant Agent and
to the Company, the retiring Warrant Agent will transfer all property held by it as Warrant Agent to the successor Warrant Agent, the resignation or removal of the retiring Warrant Agent will become effective, and the successor Warrant Agent will
have all the rights, powers and duties of the Warrant Agent under this Agreement. Upon request of any successor Warrant Agent, the Company will execute any and all instruments for fully and vesting in and confirming to the successor Warrant Agent
all such rights and powers. The Company will give notice of any resignation and any removal of the Warrant Agent, and the transfer agent, as the case may be, and each appointment of a successor Warrant Agent to all Holders, and include in the notice
the name of the successor Warrant Agent and the address of its Corporate Trust Office. 
 (d) Notwithstanding replacement of
the Warrant Agent pursuant to this Section, the Company’s obligations under Section 7.02 will continue for the benefit of the retiring Warrant Agent. 

Section 7.05. Successor Warrant Agent by Merger. If the Warrant Agent consolidates with, merges or converts into,
or transfers all or substantially all of its shareholder services business to, another Person or national banking association, the resulting, surviving or transferee Person or national banking association without any further act will be the
successor Warrant Agent with the same effect as if the successor Warrant Agent had been named as the Warrant Agent in this Agreement. 

Section 7.06. Holder Lists. The Warrant Agent shall preserve in as current a form as is reasonably practicable the
most recent list available to it of the names and addresses of all Holders. 
 ARTICLE VIII 

MISCELLANEOUS 

Section 8.01. Holder Actions. Any notice, consent to amendment, supplement or waiver provided by this Agreement to
be given by a Holder (an “act”) may be evidenced by an instrument signed by the Holder delivered to the Warrant Agent. 

  
 26 

 (a) Any act by the Holder of any Warrant binds that Holder and every
subsequent Holder of such Warrant. Subject to paragraph (c), a Holder may revoke an act as to its Warrants, but only if the Warrant Agent receives the notice of revocation before the date the amendment or waiver or other consequence of the act
becomes effective. 
 (b) The Company may, but is not obligated to, fix a record date for the purpose of determining the
Holders entitled to act with respect to any amendment or waiver or in any other regard. If a record date is fixed, those Persons that were Holders at such record date and only those Persons will be entitled to act, or to revoke any previous act,
whether or not those Persons continue to be Holders after the record date. No act will be valid or effective if given or made more than 90 days after any applicable record date with respect thereto. 

Section 8.02. Notices and Communications. Any notice or communication by the Company, on the one hand, or the
Warrant Agent, on the other hand, to the other shall be in writing and shall be deemed to have been duly given and received when delivered in person, when actually received when mailed by first class mail, postage prepaid, when actually
received by overnight delivery by a nationally recognized courier service, or when receipt has been acknowledged when sent via electronic mail (“email”). In each case the notice or communication shall be addressed as follows:

other address as the Company or the Warrant Agent may designate in writing by notice delivered to the other party in accordance with this
Section 8.02. 

  
 27 

 (a) Except as otherwise expressly provided with respect to published
notices, any notice or communication to a Holder will be deemed duly given and received (i) five days after mailing when mailed to the Holder at its address set forth below or as it appears on the Register by first class mail or (ii) on
the date sent by email of a .pdf document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent after normal business hours of the recipient; provided that if the
Company has been made aware of a different address, the Company shall provide such notice to such address instead. Copies of any notice or communication to a Holder, if given by the Company, will be mailed to the Warrant Agent at the same time.
Defect in mailing a notice or communication to any particular Holder will not affect its sufficiency with respect to other Holders. The notice or communication to the Holders should be addressed to the addresses set forth on Schedule 1 hereto. 

(b) Where this Agreement provides for notice, the notice may be waived in writing by the Person entitled to receive such
notice, either before or after the event, and the waiver will be the equivalent of the notice. Waivers of notice by Holders must be filed with the Warrant Agent, but such filing is not a condition precedent to the validity of any action taken in
reliance upon such waivers. 
 Section 8.03. Entire Agreement. This Agreement is intended by the parties hereto
as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter hereof. There are no restrictions, promises, representations,
warranties or undertakings, other than those set forth or referred to herein or in the certificates representing the Warrants, with respect to the rights granted by the Company set forth herein and therein. This Agreement supersedes all prior
written or oral agreements and understandings among the parties hereto with respect to such subject matter. 

Section 8.04. Amendments, Supplements and Waivers. The Company and the Warrant Agent may amend, supplement or
modify this Agreement or the Warrants without notice to or the consent of any Holder: 
 (i) to cure any
ambiguity, omission, inconsistency or mistake in this Agreement or the Warrants in a manner that is not inconsistent with the provisions of this Agreement and that does not adversely affect the rights, preferences and privileges of the Warrants or
any Holder; 
 (ii) to evidence and provide for the acceptance of an appointment hereunder by a successor
Warrant Agent; or 
 (iii) to make any other change that does not adversely affect the rights of any Holder.

  
 28 

 (b) Except as otherwise provided in paragraphs (a) or (c) of this
Section 8.04, this Agreement and the Warrants may be amended or modified only by means of a written amendment signed by the Company, the Warrant Agent and the Holders of a majority of the outstanding Warrants. Any amendment or modification of
or supplement to this Agreement or the Warrants, any waiver of any provision of this Agreement, and any consent to any departure by the Company or any Holder from the terms of any provision of this Agreement shall be effective only in the specific
instance and for the specific purpose for which such amendment, supplement, modification, waiver or consent has been made or given. In addition, any term of a specific Warrant may be amended or waived with the written consent of the Company and the
Holder of such Warrant. 
 (c) Notwithstanding the provisions of paragraph (b), without the consent of each Holder
affected, an amendment or waiver may not: 
 (i) increase the Exercise Price; 

(ii) reduce the term of the Warrants; 

(iii) make a material and adverse change that does not equally affect all Warrants; or 

(iv) decrease the number of shares of Common Stock, cash or other securities or property issuable upon exercise
of the Warrants 
 except, in each case, for adjustments expressly provided for in this Agreement. 

(d) It is not necessary for Holders to approve the particular form of any proposed amendment, supplement or waiver if their
consent approves the substance thereof. 
 (e) Subject to Section 8.04(h), an amendment, supplement or waiver under this
Section 8.04(e) will become effective on receipt by the Warrant Agent of written consents from the Holders of the requisite percentage of the outstanding Warrants. After an amendment, supplement or waiver under this Section 8.04(e) becomes
effective, the Company will send to the Holders affected thereby a notice describing the amendment, supplement or waiver in reasonable detail. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way
impair or affect the validity of any such amendment, supplement or waiver. 
 (f) After an amendment, supplement or waiver
becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected, pursuant to the terms of this Agreement. If the amendment, supplement or waiver is of the type requiring the consent of each Holder
affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Warrant with respect to which consent was granted. 

(g) [Reserved] 

  
 29 

 (h) The Warrant Agent shall be entitled to receive, and will be fully
protected in relying on, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this Section 8.04 is authorized or permitted by this Agreement. If the Warrant Agent has received such an
Opinion of Counsel, it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Warrant Agent. The Warrant Agent may, but shall not be obligated to, execute any amendment, supplement or waiver
that affects the Warrant Agent’s own rights, duties or immunities under this Agreement. 
 Section 8.05.
Benefits of This Agreement. Nothing in this Agreement shall be construed to give to any Person other than the Company, the Warrant Agent and the registered holders of Warrants any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the Company, the Warrant Agent and the registered holders of Warrants. 

Section 8.06. Successors and Assigns. All agreements of the Company in this Agreement and the Warrants will bind
its successors and assigns. All agreements of the Warrant Agent in this Agreement will bind its successors and assigns. Subject to the transfer conditions referred to in any legend in effect as set forth herein and Sections 3.08 and 3.09, each
Holder may freely assign its Warrants and its rights under this Agreement, in whole or in part, to any Person; provided that no such assignment shall be made to an Industry Competitor. 

Section 8.07. Governing Law; Jurisdiction and Venue; Waiver of Jury Trial. This Agreement and the Warrants shall
be governed by and construed in accordance with the laws of the State of New York (without giving effect to any principles of conflicts of laws thereof that would result in the application of the laws of any other jurisdiction, except to the extent
that the New York conflicts of laws principles would apply applicable laws of the Republic of Panama to internal matters relating to corporations organized thereunder). The Company, the Warrant Agent and each Holder of a Warrant each hereby
irrevocably and unconditionally: 
 (a) submits for itself in any legal action or proceeding relating solely to this
Agreement and the Warrant or the transactions contemplated hereby, to the exclusive jurisdiction of the courts of the State of New York and the Federal courts of the United States of America; 

(b) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or
hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same to the extent permitted by applicable law; 

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or
certified mail (or any substantially similar form of mail), postage prepaid, to the party, as the case may be, at its address set forth in Section 8.02 or at such other address of which the other party shall have been notified pursuant thereto;

  
 30 

 (d) agrees that nothing herein shall affect the right to effect service of
process in any other manner permitted by applicable law or shall limit the right to sue in any other jurisdiction for recognition and enforcement of any judgment or if jurisdiction in the courts referenced in the foregoing clause (a) are not
available despite the intentions of the parties hereto; 
 (e) agrees that final judgment in any such suit, action or
proceeding brought in such a court may be enforced in the courts of any jurisdiction to which such party is subject by a suit upon such judgment, provided that service of process is effected upon such party in the manner specified herein or
as otherwise permitted by applicable law; 
 (f) agrees that to the extent that such party has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process with respect to itself or its property, such party hereby irrevocably waives such immunity in respect of its obligations under this Agreement and the Warrants issued hereunder, to the
extent permitted by applicable law; and 
 (g) IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR
PROCEEDING IN RELATION TO THIS AGREEMENT AND THE WARRANTS ISSUED HEREUNDER. 
 Section 8.08. Severability. In
case any provision in this Agreement or in the Warrants is invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby. 

Section 8.09. Counterparts. This Agreement may be executed in any number of counterparts and by different parties
hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. Delivery of an executed
counterpart of a signature page to this Agreement by facsimile or .pdf attachment to electronic mail shall be effective as delivery of a manually executed counterpart to this Agreement. 

Section 8.10. Table of Contents and Headings. The Table of Contents and headings of the Articles and Sections of
this Agreement have been inserted for convenience of reference only, and shall not limit or otherwise affect the meaning hereof. 

Section 8.11. No Adverse Interpretation of Other Agreements. This Agreement may not be used to interpret another
agreement of the Company, and no such agreement may be used to interpret this Agreement. 
 Section 8.12. No
Presumption. If any claim is made by a party relating to any conflict, omission or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the
request of a particular party or its counsel. 

  
 31 

 Section 8.13. Obligations Limited to Parties to This Agreement and
Holders. Each of the parties hereto covenants, agrees and acknowledges that, other than as set forth herein, no Person other than the Warrant Agent, the Holders, their respective permitted assignees and the Company shall have any obligation
hereunder and that, notwithstanding that one or more of such Persons may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith shall be had
against any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of such Persons or their respective permitted assignees, or any former, current or future
director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable
law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager,
member, stockholder or Affiliate of any of such Persons or any of their respective assignees, or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the
foregoing, as such, for any obligations of such Persons or their respective permitted assignees under this Agreement or any documents or instruments delivered in connection herewith or for any claim based on, in respect of or by reason of such
obligation or its creation, except, in each case, for any assignee of any Holder hereunder. 
 Section 8.14. Bank

deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer
Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare shall have no responsibility or liability for any diminution of the Funds that may result from any deposit made by Computershare in accordance with this paragraph, including
any losses resulting from a default by any bank, financial institution or other third party. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits. Computershare shall not be obligated to
pay such interest, dividends or earnings to the Company, any holder or any other party. 
 Section 8.15. Further
Assurances. The Company shall perform, acknowledge and deliver or cause to be performed, acknowledged and delivered all such further and other acts, documents, instruments and assurances as may be reasonably required by the Warrant Agent for the
carrying out or performing by the Warrant Agent of the provisions of this Agreement. 

  
 32 

 Section 8.16. Confidentiality. The Warrant Agent and the Company
agree that all books, records, information and data pertaining to the business of the other party, including personal, non-public Holder information, which are exchanged or received pursuant to the negotiation
or the carrying out of this Agreement including the fees for services agreed upon by the parties hereto shall remain confidential, and shall not be voluntarily disclosed to any other Person, except as may be required by law or regulation, including
pursuant to subpoenas from state or federal government authorities (e.g., in divorce and criminal actions). 

Section 8.17. Force Majeure. Notwithstanding anything to the contrary contained herein, the Warrant Agent will not

[Reverse of Series B Warrant] 
  

	1.	 Warrant Agreement 

The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants issued or to be issued
pursuant to a Warrant Agreement dated as of December 2, 2019 (the “Warrant Agreement”), among the Company and Computershare Inc., a Delaware corporation (“Computershare”), and its wholly owned subsidiary
Computershare Trust Company, N.A., a federally chartered trust company (collectively, the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to
for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the registered holders
or registered holder) of the Warrants. To the extent permitted by applicable law, in the event of an inconsistency or conflict between the terms of this Warrant and the Warrant Agreement, the terms of the Warrant Agreement will prevail. 

 

	2.	 Exercise 

Warrants may be exercised at any time from 9:00 a.m., New York City time, on December 2, 2019 and on or before the
Expiration Time. 
 In order to exercise all or any of the Warrants represented by this Warrant Certificate, the holder must
deliver to the Company the form of election to exercise on the reverse hereof duly completed, which signature shall be medallion guaranteed by an institution which is a member of a Securities Transfer Association recognized signature guarantee
program. 
 The exercise of Warrants is subject to certain restrictions on exercise (including a minimum number of Warrants
being exercised in a partial exercise of Warrants) as described in the Warrant Agreement. 
 No Warrant may be exercised
after the Expiration Time, and, to the extent not exercised by such time, the Warrants evidenced hereby shall become void. 
  

	3.	 Adjustments 

The Warrant Agreement provides that, upon the occurrence of certain events, the Exercise Price and, if applicable, the number
of shares of Common Stock issuable upon the exercise of each Warrant shall be adjusted. 

  
 A-4 

	4.	 No Fractional Shares 

No fractions of a share of Common Stock will be issued upon the exercise of any Warrant, but the Company will pay the cash
value thereof determined as provided in the Warrant Agreement. 
  

	5.	 Book-Entry Form; Transfer 

The Warrants have been issued in book-entry form. 

The Company and the Warrant Agent may deem and treat the registered holder(s) as shown on the Register as the absolute
owner(s) of this Warrant, for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. This Warrant
does not entitle any holder hereof to any rights of a stockholder of the Company. 
  

	6.	 Governing Law; Jurisdiction and Venue; Waiver of Jury Trial 

This Warrant shall be governed by and construed in accordance with the laws of the State of New York (without giving effect to
any principles of conflicts of laws thereof that would result in the application of the laws of any other jurisdiction, except to the extent that the New York conflicts of laws principles would apply applicable laws of the Republic of Panama to
internal matters relating to corporations organized thereunder). The Company and the Holder of this Warrant each hereby irrevocably and unconditionally: 

(i) submits for itself in any legal action or proceeding relating solely to this Warrant or the transactions
contemplated hereby, to the exclusive jurisdiction of the courts of the State of New York and the Federal courts of the United States of America, in each case located within the Southern District of New York, and appellate courts thereof; 

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that
it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same to the extent permitted by applicable law;

 (iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy
thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the party, as the case may be, at its address set forth in the Register or at such other address of which the other party shall have been
notified pursuant to the provisions of the Warrant Agreement; 

  
 A-5

 ARTICLE II 

REGISTRATION RIGHTS 

Section 2.01. Shelf Registration. 

(a) Resale Shelf Registration Statements. Within 15 days of each issuance of Registrable Securities pursuant to either
of the Financing Agreements, the Company shall use its commercially reasonable efforts to prepare and file with the SEC a registration statement (including a prospectus supplement to an already effective registration statement) covering the sale or
distribution from time to time by the Holders, on a delayed or continuous basis pursuant to Rule 415 or Rule 424(b)(7), as applicable, of the Securities Act, to permit the public resale of such Registrable Securities on the terms and conditions
specified in this Section 2.01 (the “Resale Shelf Registration Statement”) or, if Registrable Securities are issued pursuant to either of the Agreements after the filing of the Resale Shelf Registration Statement, to use its
commercially reasonable efforts to amend the Shelf Registration Statement, or file a new Shelf Registration Statement, within 10 days to include such additional Registrable Securities. If any additional Common Shares become Registrable Securities,
the Company shall use its commercially reasonable efforts to amend the Shelf Registration Statement (including a prospectus supplement to an already effective registration statement), or file a new Shelf Registration Statement, within 10 days to
include such additional Common Shares. Each Resale Shelf Registration Statement filed with the SEC pursuant to this Section 2.01 shall be on Form S-3 or, if Form
S-3 is not then available to the Company, on Form S-1 or such other form of registration statement as is then available to effect a registration for resale of the
Registrable Securities, covering the Registrable Securities, and shall contain a prospectus in such form as to permit any Selling Holder covered by such Resale Shelf Registration Statement to sell such Registrable Securities pursuant to Rule 415
under the Securities Act (or any successor or similar provision adopted by the SEC then in effect) at any time beginning on the Effective Date for such Resale Shelf Registration Statement and while such Resale Shelf Registration continues to be
effective under the Securities Act. The Company shall use its commercially reasonable efforts to cause any Resale Shelf Registration Statement filed pursuant to this Section 2.01 to be declared effective as soon as practicable after the filing
thereof (it being agreed that each Resale Shelf Registration Statement shall be an automatic shelf registration statement that shall become effective upon filing with the SEC pursuant to Rule 462(e) if Rule 462(e) is available to the Company), but
in any event by the Effectiveness Deadline. 
 (b) Subsequent Shelf Registration Statement. If a Shelf Registration
Statement filed pursuant to this Agreement ceases to be effective under the Securities Act for any reason at any time during the Effectiveness Period, the Company shall use its commercially reasonable efforts as promptly as is reasonably practicable
to cause such Shelf Registration Statement to again become effective under the Securities Act, and shall use its commercially reasonable efforts as promptly as is reasonably practicable to amend such Shelf Registration Statement in a manner
reasonably expected to result in the withdrawal of any order of the SEC suspending the effectiveness of such Shelf Registration Statement or file an additional registration statement (a “Subsequent Shelf Registration Statement”) for
an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by the Holders thereof of all securities that are Registrable Securities as of the time of such filing and
not registered pursuant to another Shelf Registration Statement. If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to cause such Subsequent Shelf Registration Statement to become
effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration Statement shall be an automatic shelf registration statement that shall become effective
upon filing with the SEC pursuant to Rule 462(e) if Rule 462(e) is 

  
 7 

 
available to the Company) and (b) keep such Subsequent Shelf Registration Statement continuously effective until the end of the Effectiveness Period. Any such Subsequent Shelf Registration
Statement shall be a registration statement on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration Statement shall be on another appropriate form
and shall contain a prospectus in such form as to permit any Selling Holder covered by such Resale Shelf Registration Statement to sell Registrable Securities held by it pursuant to Rule 415 under the Securities Act (or any successor or similar
provision adopted by the SEC then in effect) at any time beginning on the Effective Date for such Subsequent Shelf Registration Statement. 

(c) Effectiveness Period. A Shelf Registration Statement shall provide for the resale pursuant to any method or
combination of methods legally available to, and requested by, the Selling Holders; provided that no Shelf Registration Statement shall provide for the distribution of Registrable Securities through underwritten offerings. During the Effectiveness
Period, the Company shall, subject to the applicable provisions of the Securities Act, use its commercially reasonable efforts to cause a Shelf Registration Statement filed pursuant to this Section 2.01 to remain effective, and to be
supplemented and amended to the extent necessary to ensure that such Shelf Registration Statement is available or, if not available, that another registration statement is available for the resale of the Registrable Securities until all Registrable
Securities have ceased to be Registrable Securities. The Company shall prepare and file all necessary information with the NYSE (or such other national securities exchange on which the Registrable Securities are then listed and traded) to list the
Registrable Securities (other than the Preferred Shares) covered by a Shelf Registration Statement and shall use its commercially reasonable efforts to have such Registrable Securities approved for listing on the NYSE (or such other national
securities exchange on which the Registrable Securities are then listed and traded) by the date of any sale or distribution of such Registrable Securities, subject only to official notice of issuance. As soon as practicable following the Effective
Date of a Shelf Registration Statement, but in any event within three Business Days of such date, the Company shall notify the Holders of the effectiveness of such Shelf Registration Statement.  

Section 2.02. Delay Rights. Notwithstanding anything to the contrary contained herein, the Company may, upon
written notice (a “Delay Notice”) to (i) all Holders, delay the filing of a Shelf Registration Statement required under Section 2.01, or (ii) all Selling Holders whose Registrable Securities are included in a Shelf
Registration Statement or other registration statement contemplated by this Agreement, suspend such Selling Holders’ use of any prospectus that is a part of such Shelf Registration Statement or other registration statement (in which event the
Selling Holder shall discontinue sales of the Registrable Securities pursuant to such Shelf Registration Statement or other registration statement contemplated by this Agreement but may settle any previously made sales of Registrable Securities) if
the Company (x) is pursuing an acquisition, merger, tender offer, reorganization, disposition, financing, securities offering or other similar transaction and the Board determines in good faith that (A) the Company’s ability to pursue
or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in such Shelf Registration Statement or other registration statement (in each case, including any document incorporated by
reference therein) or (B) such transaction or the pursuit thereof renders the Company unable to comply with SEC requirements, in each case under circumstances that would make it impractical or inadvisable to cause the Shelf Registration
Statement (or such filings) to become effective or to promptly amend or supplement 

  
 8 

 
the Shelf Registration Statement on a post-effective basis, as applicable, (y) has experienced some other material non-public event the disclosure of
which at such time, in the good faith judgment of the Board, would materially adversely affect the Company or (z) would, in the absence of such delay or suspension, either be required to prematurely disclose material information that the
Company has a bona fide business purpose for preserving as confidential or would be rendered unable to comply with the requirements under the Securities Act or the Exchange Act; provided, however, in no event shall (A) such filing
of such Shelf Registration Statement be delayed under this Section 2.02 for a period that exceeds 90 calendar days or (B) such Selling Holders be suspended under this Section 2.02 from selling Registrable Securities pursuant to such
Shelf Registration Statement or other registration statement for a period that exceeds an aggregate of 90 calendar days in any 365 calendar-day period. The Holders agree to keep the existence and contents of
any Delay Notice confidential and not to use such information for any other purpose. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice, but in any event within one
Business Day of such disclosure or termination, to the Selling Holders whose Registrable Securities are included in such Shelf Registration Statement and shall promptly terminate any suspension of sales it has put into effect and shall take such
other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement. Notwithstanding anything to the contrary in this Agreement, the Company may amend any Shelf Registration Statement as necessary (the
“Financing Amendments”) to include Registrable Securities under this Agreement or any other Registration Rights Agreement with Lenders, and any lapse in effectiveness of such Financing Amendment shall be deemed not to constitute a
suspension of Selling Shareholders’ use of a prospectus under Section 2.02(ii). 
 Section 2.03. [Reserved]

 Section 2.04. Sale Procedures. In connection with its obligations under this Article II, the Company shall,
as expeditiously as possible: 
 (a) prepare and promptly file with the SEC a Shelf Registration Statement with respect to
any Registrable Securities and use commercially reasonable efforts to cause such Shelf Registration Statement to become and remain effective for the Effectiveness Period, in accordance with and subject to the applicable provisions of this Agreement
and the Securities Act; 
 (b) furnish to the Holders’ legal counsel copies of each Shelf Registration Statement and the
prospectus included therein (including each preliminary prospectus) proposed to be filed and provide such legal counsel a reasonable opportunity to review and comment on any such Shelf Registration Statement; 

(c) prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any Shelf
Registration Statement and the prospectus used in connection herewith as may be necessary to keep any such Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities
Act with respect to the disposition of all Registrable Securities covered by any such Shelf Registration Statement in accordance with the Selling Holders’ intended method of distribution set forth in such Shelf Registration Statement; 

  
 9 

 (d) to the extent not publicly available, furnish or otherwise make
available to the Selling Holder’s legal counsel (i) as far in advance as reasonably practicable before filing a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment
thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the SEC other
than annual or quarterly reports on Forms 10-K or 10-Q, respectively, current reports on Form 8-K or proxy statements), and
provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect
to such information prior to filing a Shelf Registration Statement or such other registration statement or supplement or amendment thereto, and (ii) such number of copies of such Registration Statement or such other registration statement and
the prospectus included therein and any supplements and amendments thereto as such Selling Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration
Statement or other registration statement; 
 (e) if applicable, use its commercially reasonable efforts to register or
qualify the Registrable Securities covered by a Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably
request; provided, however, that the Company shall not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of
process or taxation in any such jurisdiction where it is not then so subject; 
 (f) upon request and subject to appropriate
confidentiality obligations, furnish to the Selling Holder’s legal counsel copies of any and all transmittal letters or other material correspondence with the SEC or any other governmental agency or self-regulatory body or other body having
jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities; 

(g) promptly notify the Selling Holder’s legal counsel, at any time when a prospectus relating thereto is required to be
delivered by any of them under the Securities Act, of (i) the filing of a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection
therewith, or any amendment or supplement thereto, and, with respect to such Shelf Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; (ii) the receipt of any
written comments from the SEC with respect to any filing referred to in clause (i); and (iii) any written request by the SEC for amendments or supplements to such Shelf Registration Statement or any other registration statement or any
prospectus or prospectus supplement thereto or for additional information; 
 (h) promptly notify the Selling Holder’s
legal counsel, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in a Shelf Registration
Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact 

  
 10 

 
required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which such
statements are made); (ii) the issuance or express threat of issuance by the SEC of any stop order suspending the effectiveness of such Shelf Registration Statement or any other registration statement contemplated by this Agreement, or the
initiation of any proceedings for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws
of any jurisdiction. Following the provision of such notice, the Company agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus
supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they are made
and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make
available to its security holders, as soon as reasonably practicable, an earnings statement, covering a period of 12 months beginning within three months after the Effective Date of such Shelf Registration Statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 
 (j) use its
commercially reasonable efforts to cause all such Registrable Securities (other than Preferred Shares) registered pursuant to this Agreement to be listed on the primary securities exchange or nationally recognized quotation system on which such
Registrable Securities are then listed or quoted with the same CUSIP; 
 (k) use its commercially reasonable efforts to cause
the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the Selling Holders to consummate the disposition
of such Registrable Securities; and 
 (l) provide the same transfer agent and registrar used in connection with similar
securities issued by the Company for all Registrable Securities covered by such registration statement not later than the Effective Date of such registration statement. 

The Company shall not name a Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act in any Shelf
Registration Statement without such Holder’s consent. 
 Each Selling Holder, upon receipt of notice from the Company
of the happening of any event of the kind described in Section 2.04(g)(iii) or Section 2.04(h) shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling
Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.04(g)(iii) or Section 2.04(h) or until it is advised in writing by the Company that the use of the prospectus may be resumed and has
received copies of any additional or supplemental filings incorporated by reference in the prospectus (such period during which disposition is discontinued being an “Interruption Period”), and, if so directed by

  
 11 

 
the Company, such Selling Holder shall deliver to the Company (at the Company’s expense) all copies in their possession or control, other than permanent file copies then in such Selling
Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. As soon as practicable after the Company has determined that the use of the applicable prospectus may be resumed, the
Company will notify the Selling Holders thereof. In the event the Company invokes an Interruption Period hereunder and, in the discretion of the Company, the need for the Company to continue the Interruption Period ceases for any reason, the Company
shall, as soon as reasonably practicable, provide written notice to the Selling Holders that such Interruption Period is no longer applicable. 

Section 2.05. Cooperation by Holders. The Company shall have no obligation to include Registrable Securities of a
Holder in a registration statement who (a) has not returned a fully completed Selling Stockholder Questionnaire in the form attached hereto as Exhibit A or (b) has failed to timely furnish after receipt of a written request from the
Company such information that the Company determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the applicable provisions of the
Securities Act. 
 Section 2.06. Expenses. The Company shall pay all reasonable Registration Expenses, as
determined in good faith by the Board. Each Selling Holder shall pay its Selling Expenses in connection with any sale of its Registrable Securities hereunder. In addition, except as otherwise provided in Section 2.07, the Company shall not be
responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. 

Section 2.07. Indemnification. 

(a) By the Company. In the event of a registration of any Registrable Securities under the Securities Act pursuant to
this Agreement, the Company shall indemnify and hold harmless each Selling Holder thereunder, and its directors, officers, managers, employees, agents and Affiliates and each Person, if any, who controls such Selling Holder or its Affiliates within
the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities
(including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar
as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (a) any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of
the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) any registration statement contemplated by this Agreement, any preliminary prospectus, prospectus
supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto or (b) arise out of or are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and the Company shall reimburse each such Selling Holder Indemnified
Person for any legal or other expenses reasonably incurred by them in connection with investigating, defending or resolving any such Loss or actions or 

  
 12 

 
proceedings; provided, however, that the Company shall not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in any such document. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and shall survive the transfer of such securities by such Selling Holder. 

(b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the
Company, its directors, officers, employees and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the
foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in any registration statement
contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto; provided, however, that
the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

 (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it from any
liability that it may have to any indemnified party under this Section 2.07 except to the extent that the indemnifying party is materially prejudiced in its ability to defend such action by such failure. In any action brought against any
indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably
satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under
this Section 2.07 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ
counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be
reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, then the indemnified party shall have the right to select one separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate
counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any
indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party (which shall 

  
 13 

 
not be unreasonably withheld, delayed or conditioned), unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability
of, the indemnified party. In addition, no indemnifying party shall be liable for the settlement of any action effected without its prior written consent (which shall not be unreasonably withheld, delayed or conditioned). 

(d) Contribution. If the indemnification provided for in this Section 2.07 is held by a court or government agency
of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the
statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the
dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party
on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information
supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions
pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 2.07 shall be in addition to any other rights to
indemnification or contribution that an indemnified party may have pursuant to applicable Law, contract or otherwise. 

Section 2.08. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of
the SEC that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to: 

(a) make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144
under the Securities Act (or any successor or similar provision adopted by the SEC then in effect), at all times from and after the date hereof; 

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and
the Exchange Act at all times from and after the date hereof; and 
 (c) so long as a Holder owns any Registrable Securities,
furnish, unless otherwise available electronically at no additional charge via the SEC’s EDGAR system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and
documents as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Holder to sell any such securities without registration. 

  
 14 

 Section 2.09. Transfer or Assignment of Registration Rights. The
rights to cause the Company to register Registrable Securities granted to the Purchasers by the Company under this Article II may be transferred or assigned by the Purchasers to one or more transferees or assignees of Registrable Securities without
the consent of the Company; provided, however, that, (a) the transfer or assignment relates to a transfer or assignment of Warrants made in accordance with the applicable provisions of the Warrant Agreement, (b) the transfer or
assignment relates to a transfer or assignment of Preferred Shares made in accordance with the applicable provisions of the Certificate of Designation, (c) any such transfer or assignment is for a number of Registrable Securities representing
an aggregate Registrable Securities Amount of at least $5 million or any such transfer or assignment is to a Permitted Transferee, (d) the Company is given written notice prior to any said transfer or assignment, stating the name and
address of each of the transferee or assignee, (e) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of the Purchasers under this Agreement and (f) the transferor or assignor is not
relieved of any obligations or liabilities hereunder arising out of events occurring prior to such transfer. 

Section 2.10. Liquidated Damages Payments Under Certain Circumstances. 

(a) Payments (“Liquidated Damages Payments”) with respect to the Registrable Securities required to be covered
by the Resale Shelf Registration Statement shall be assessed if (i) such Registrable Securities are not covered by an effective Resale Shelf Registration Statement by the Effectiveness Deadline or at any time during the Effectiveness Period or
(ii) the Company has not filed a Resale Shelf Registration Statement by the deadline for filing set forth in Section 2.01(a), after giving effect to any Delay Notice(a “Registration Default”).
Liquidated Damages Payments shall accrue on such Registrable Securities (based on the Common Share Price as of such Business Day) for each such day from and including the date on which any such Registration Default occurs to but excluding the date
on which all such Registration Defaults have been cured, at a rate of 6% per annum. Liquidated Damages Payments shall be paid in accordance with Section 2.10(c) below. Other than the obligation of payment of any Liquidated Damages Payments in
accordance with the terms hereof, the Company will have no other liabilities for monetary damages with respect to its registration obligations. With respect to each Holder, the Company’s obligations to pay Liquidated Damages Payments remain in
effect only so long as the securities held by the Holder are Registrable Securities. 
 (b) In the event the Company provides
a Delay Notice pursuant to Section 2.02, a Registration Default shall be deemed not to have occurred and be continuing, and no Liquidated Damages Payments shall accrue as a result thereof, in relation to the Resale Shelf Registration Statement
or the related prospectus, until the end of the 90-day period described in Section 2.02. 

  
 15 

 (c) Any amounts of Liquidated Damages Payments due pursuant to this
Section 2.10 will be payable in cash to the applicable Holders on every thirtieth day (pro rated for shorter periods) after the day of a Registration Default thereafter until the earlier of (x) the date on which such Registration Default
is cured and (y) the date on which the Registrable Securities cease to be Registrable Securities under this Agreement; provided, however, to the extent the Company is unable to pay Liquidated Damages Payments in cash because such
payment would result in a breach under a credit facility or other debt instrument, then the Company will pay such Liquidated Damages Payments using as much cash as the Company is permitted without causing a breach of or default under such credit
facility or other debt instrument. The amount of Liquidated Damages Payments will be determined on the basis of a 360-day year comprised of twelve 30-day months and the
actual number of days on which Liquidated Damages Payments accrued during such period.

 Section 3.04. Amendments and Waivers. This Agreement may be
amended only by means of a written amendment signed by the Company and the Holders of greater than 50% of the Registrable Securities then outstanding that are Common Shares issued, Common Shares issuable upon the exercise of the Warrants and
Preferred Shares; provided that any amendment of any of the provisions of this Agreement which disproportionately materially adversely affects any Holder shall not be effective without the written approval of such Holder. Any Holder may (with
respect to itself), at any time: (i) extend the time for the performance of any of the obligations of the Company; or (ii) waive compliance by the Company with any of its agreements or covenants contained herein. The Company may, at any

to be bound thereby. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of
Registrable Securities whose securities are to be offered or distributed pursuant to a Registration Statement, and that does not affect the rights of other Holders, may be given by Holders of greater than 50% of the Registrable Securities to be

 Section 3.05. Binding Effect;
Benefits of This Agreement. This Agreement shall inure to the benefit of and be binding upon each of the parties hereto and their respective successors and assigns, including subsequent Holders of Registrable Securities (but only to the extent

under or by reason of this Agreement. 
 Section 3.06. Successor Entity. The Company shall not change its form
of organization (i.e., to a partnership or other form of entity), or merge or consolidate into any other Person, unless such changed or successor entity agrees to be bound by this Agreement.

of the Purchasers under this Agreement may be transferred or assigned by each such Purchaser only in accordance with Section 2.09.

set forth herein with respect to any and all equity interests of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in
substitution of, the Registrable Securities, and shall be appropriately adjusted for any combinations, share splits, recapitalizations, pro rata distributions of shares and the like occurring after the date of this Agreement. 

Section 3.09. Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be
difficult, if not impossible, to ascertain, and it is therefore agreed that each such party, in addition to and without limiting any other remedy or right it may have, shall have the right to seek an injunction or other equitable relief in a court
of competent jurisdiction in accordance with Section 3.09, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto, to the extent permitted by applicable Law, hereby waives any and
all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right shall not preclude any such party from pursuing any other rights and
remedies at law or in equity that such party may have. 

  
 18

Trial. This Agreement shall be governed by and construed in accordance with the laws of the State of New York (without giving effect to any principles of conflicts of laws thereof that would result in the application of the laws of any other
