 An Officer shall sign the Warrants on behalf of the Company by manual signature. 
 If the Officer whose signature is on a Warrant no longer holds that office at the time a Warrant is countersigned, the Warrant shall nevertheless be
valid. 
 A Warrant shall not be valid until countersigned by the manual signature of the Warrant Agent. The signature shall be conclusive
evidence that the Warrant has been properly issued under this Warrant Agreement. 
 The Warrant Agent shall, upon a written order of the
Company signed by an Officer (a “Warrant Countersignature Order”), countersign (i) one Global Warrant evidencing 750 Warrants issued as of the date hereof, and (ii) one Global Warrant evidencing any additional
Warrants issued by the Company after the date hereof pursuant to the next sentence of this paragraph. The Warrants need not be issued at one time and unless otherwise provided, the Warrants may also be issued by the Company and countersigned and

Warrants issued on the date hereof, not to exceed 1,000 Warrants. 
 The Warrant Agent may appoint an agent acceptable to the Company to
countersign Warrants. Such an agent may countersign Warrants whenever the Warrant Agent may do so. Each reference in this Warrant Agreement to a countersignature by the Warrant Agent includes a countersignature by such agent. Such an agent has the
same rights as the Warrant Agent to deal with the Company or an Affiliate of the Company.

registration of transfer or for exchange (“Warrant Registrar”). The Warrant Registrar shall keep a register of the Warrants and of their registration of transfer and exchange (the “Warrant Register”).
The Company may appoint one or more co-Warrant Registrars. The term “Warrant Registrar” includes any co-Warrant Registrar. The Company may change any Warrant Registrar without notice to any holder. The Company shall notify the Warrant
Agent in writing of the name and address of any agent not a party to this Warrant Agreement. If the Company fails to appoint or maintain another entity as Warrant Registrar, the Warrant Agent shall act as such. The Company or any of its subsidiaries
may act as Warrant Registrar. 
 The Company initially appoints the Warrant Agent to act as the Warrant Registrar with respect to the Global
Warrants. 
 The Company initially appoints the Warrant Agent to act as Common Depositary with respect to the Global Warrants. 
 3.4 HOLDER LISTS 
 The Warrant Registrar 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 of Warrants. If the Warrant Agent is not the
Warrant Registrar, the Company shall promptly furnish to the Warrant Agent at such times as the Warrant Agent may request in writing, a list in such form and as of such date as the Warrant Agent may reasonably require of the names and addresses of
the holders. 
 3.5 TRANSFER AND EXCHANGE 
 (a) In accordance with the terms of this Warrant Agreement, the Warrant Agent shall deliver at the cost of the Company, upon not less than 45 days’
notice to the Warrant Agent by Euroclear or Clearstream, the relevant Warrants in definitive form (“Definitive Warrants”) in exchange for interests in such Global Warrant. For this purpose, the Warrant Agent is authorized and
it shall (A) authenticate each such Definitive Warrant and (B) deliver each such Definitive Warrant to or to the order of Euroclear or Clearstream, in exchange for interests in such Global Warrant. The Warrant Agent shall promptly notify
the Company upon receipt of a request for issue of Definitive Warrants the aggregate number of Warrants represented by the relevant Global Warrant to be exchanged in connection therewith. The Company undertakes to deliver to, or to the order of, the
Warrant Agent sufficient numbers of duly executed Definitive Warrants to enable the Warrant Agent to comply with its obligations under this Section 3.5(a). Transfer of a Global Warrant by the Common Depositary to another shall be limited
to transfer of such Global Warrant in whole, but not in part, to nominees of Euroclear or Clearstream, to a successor of Euroclear or Clearstream, such successor’s nominee, or such depositary other than the Common Depositary (or its nominee) as
the Company may designate. Notwithstanding the above, interests in a Global Warrant shall be exchangeable in whole (but not in part) at the cost of the Company for Definitive Warrants if either Euroclear or Clearstream or any other relevant clearing
system ceases to operate as a clearing system for 14 

  

 6 








 
consecutive days (other than by reason of public holiday) or announces an intention to permanently cease business and it shall not be practicable to transfer
the relevant Warrants to another clearing system within 90 days. 
 (b) Upon any exchange of an interest in a Global Warrant for Definitive
Warrants, the relevant Global Warrant shall be endorsed by the Warrant Agent to reflect the reduction of the number of Warrants so exchanged. Until exchanged in full, the holder of any interest in any Global Warrant shall in all respects be entitled
to the same benefits under this Warrant Agreement as Definitive Warrants authenticated and delivered hereunder. Once exchanged in full, a Global Warrant shall be canceled and disposed of by the Warrant Agent in accordance with its customary
procedures. 
 (c) The Warrant Agent shall cause all Global Warrants and Definitive Warrants delivered to it and held by it hereunder to be
maintained in safe custody in accordance with this Section 3.5, and shall ensure that such Warrants are issued only in accordance with the provisions of this Warrant Agreement. 
 (d) The Warrant Agent shall be entitled to treat a facsimile communication from a person purporting to be (and who the Warrant Agent believes in good
faith to be) the authorized representative of the Company, named in a list furnished to the Warrant Agent from time to time, as sufficient instructions and authority of the Company for the Warrant Agent to act in accordance with this
Section 3.5. 
 (e) Title to the Definitive Warrants shall pass by notation on the Warrant Register. However, title to Warrants
issued in the form of Global Warrants held through Euroclear and Clearstream shall be transferable only in accordance with the rules and procedures of Euroclear and Clearstream, as appropriate. 
 (f) General Provisions Relating to Transfers and Exchanges 
 (1) To permit registrations of transfers and exchanges, the Company shall execute and the Warrant Agent shall countersign Global Warrants
and Definitive Warrants upon the Company’s order or at the Warrant Registrar’s request. 
 (2) The Company hereby
agrees and instructs the Warrant Agent that the Warrant Registrar shall not register the proposed transfer of any beneficial interest in, or proposed exercise of any right in, any Warrant, unless the Warrant Registrar shall have first received
certification in the form of Exhibit B hereto that such transfer or exercise is made in accordance with the provisions of Regulation S. 
 (3) The Warrant Register shall be in written form in the English language and shall include a record of the certificate number of each Warrant issued, and shall show the number of Warrants, the date of issue, all
subsequent transfer and changes of ownership in respect thereof and the names, tax identifying numbers (if relevant to a specific holder) and addresses of the holders. 
 (4) The Warrant Registrar shall at all reasonable times during office hours make the Warrant Register available to the Company, the
Warrant Agent, the 

  

 7 








 
holders of Warrants or any person authorized by the Company in writing for inspection and for the taking of copies thereof or extracts therefrom, and at the
expense of the Company, the Warrant Registrar shall deliver to such persons all lists of holders of Warrants, their addresses, number of holdings and other details as they may request. 
 (5) The Warrant Registrar shall only register the transfer of an interest in a Warrant if the requested transfer is (i) to the
Company (including its affiliates); (ii) being made by a person who has provided the Warrant Registrar with a certification in the form of Exhibit B hereto; (iii) pursuant to an effective registration statement under the Securities
Act with certification to that effect from such holder; or (iv) being transferred in reliance on any other exemption from the registration requirements of the Securities Act (including Rule 904 thereunder), with a certification to that effect
from such holder and an opinion of counsel from such holder or the transferee reasonably acceptable to the Company and to the Warrant Registrar to the effect that such transfer is in compliance with the Securities Act. 
 (6) No service charge shall be made to a holder of a beneficial interest in a Global Warrant or to a holder of a Definitive Warrant for
any registration of transfer or exchange, but the Company or the Warrant Agent may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith and may require that a Person receiving
Definitive Warrants must bear the cost of insurance, postage, transportation and the like in the event that such Person does not receive such Definitive Warrants in person at the offices of an Warrant Agent. 
 (7) All Global Warrants and Definitive Warrants issued upon any registration of transfer or exchange of Global Warrants or Definitive
Warrants shall be the duly authorized, executed and issued warrants for Common Shares of the Company, not subject to any preemptive rights, and entitled to the same benefits under this Warrant Agreement, as the Global Warrants or Definitive Warrants
surrendered upon such registration of transfer or exchange. 
 (8) Prior to due presentment for the registration of a transfer
of any Warrant, the Warrant Agent, and the Company may deem and treat the Person in whose name any Warrant is registered as the absolute owner of such Warrant for all purposes and none of the Warrant Agent, or the Company shall be affected by notice
to the contrary. 
 (9) The Warrant Agent shall countersign Global Warrants and Definitive Warrants in accordance with the
provisions of Section 3.2 hereof. 
 (g) Facsimile Submissions to Warrant Agent 
 All certifications, certificates and Opinions of Counsel required to be submitted to the Warrant Registrar pursuant to this Section 3.5 to
effect a registration of transfer or exchange may be submitted by facsimile. 
 Notwithstanding anything herein to the contrary, as to any
certificates and/or certifications delivered to the Warrant Registrar pursuant to this Section 3.5, the Warrant 

  

 8 








 
Registrar’s duties shall be limited to confirming that any such certifications and certificates delivered to it are in the form of Exhibit B
attached hereto. The Warrant Registrar shall not be responsible for confirming the truth or accuracy of representations made in any such certifications or certificates. As to any Opinions of Counsel delivered pursuant to this
Section 3.5, the Warrant Registrar may rely upon, and be fully protected in relying upon, such opinions. 
 3.6
REPLACEMENT WARRANTS 
 If any mutilated Warrant is surrendered to the Warrant Agent or the
Company and the Warrant Agent receives evidence to its satisfaction of the destruction, loss or theft of any Warrant, the Company shall issue and the Warrant Agent, upon receipt of a Warrant Countersignature Order, shall countersign a replacement
Warrant if the Warrant Agent’s requirements are met. If required by the Warrant Agent or the Company, an indemnity bond must be supplied by the holder that is sufficient in the judgment of the Warrant Agent and the Company to protect the
Company, the Warrant Agent, any Agent and any agent for purposes of the countersignature from any loss that any of them may suffer if a Warrant is replaced. The Company may charge any holder of Warrants for the Company’s expenses in replacing a
Warrant. 
 Every replacement Warrant is an additional warrant of the Company and shall be entitled to all of the benefits of this Warrant
Agreement equally and proportionately with all other Warrants duly issued hereunder. 
 3.7 TEMPORARY
WARRANTS 
 Until certificates representing Warrants are ready for delivery, the Company may prepare and the
Warrant Agent, upon receipt of a Warrant Countersignature Order, shall issue temporary Warrants. Temporary Warrants shall be substantially in the form of certificated Warrants but may have variations that the Company considers appropriate for
temporary Warrants and as shall be reasonably acceptable to the Warrant Agent. Without unreasonable delay, the Company shall prepare and the Warrant Agent shall countersign Definitive Warrants in exchange for temporary Warrants. 
 Holders of temporary Warrants shall be entitled to all of the benefits of this Warrant Agreement. 
 3.8 CANCELLATION 
 The Company at any time may deliver Warrants to the Warrant Agent for cancellation. The Warrant Registrar and Warrant Agent shall forward to the Warrant Agent any Warrants surrendered to them for registration of
transfer, exchange or exercise. The Warrant Agent and no one else shall cancel all Warrants surrendered for registration of transfer, exchange, exercise, replacement or cancellation and shall destroy canceled Warrants (subject to the record
retention requirement of the Exchange Act). Upon the Company’s written request, certification of the destruction of all cancelled Warrants shall be delivered to the Company. The Company may not issue new Warrants to replace Warrants that have
been exercised or that have been delivered to the Warrant Agent for cancellation.

 SECTION 4. SEPARATION OF WARRANTS; EXERCISE OF WARRANTS; TERMS OF WARRANTS 
 (a) The Floating Rate Notes and Warrants will be separately transferable from the date hereof. Subject to the terms of this Agreement, each holder of
Warrants shall have the right, which may be exercised during the period commencing at the date of the Qualifying IPO (which, for the avoidance of doubt, shall include the right of holders of Warrants to exercise their Warrants in order to sell
Warrant Shares in the Qualifying IPO) and until 5:00 p.m., Hong Kong time, on the Warrant Expiration Date (the “Exercise Period”), to receive from the Company the number of fully paid and nonassessable Warrant Shares which
the holder may at the time be entitled to receive on exercise of such Warrants and payment of the applicable Exercise Price (i) in cash, by wire transfer or by certified or official bank check payable to the order of the Company, (ii) by
tendering Floating Rate Notes having a principal amount of premium, interest, and other amounts actually outstanding at the time of tender equal to the applicable Exercise Price then in effect, (iii) by tendering Warrants as set forth below or
(iv) any combination of cash, Floating Rate Notes or Warrants. Each holder may elect, upon exercise of its Warrants during the applicable Exercise Period, to receive Warrant Shares on a net basis, such that, without the exchange of any funds
and in satisfaction of and without any obligation to pay the Exercise Price, the holder will receive such number of Warrant Shares as shall equal the product of (A) the number of Warrant Shares for which such Warrant is exercisable as of the
date of exercise (if the Exercise Price were being paid in cash) and (B) the Cashless Exercise Ratio. The “Cashless Exercise Ratio” shall be calculated by the Company and shall equal a fraction the numerator of which is
the Market Value (as defined below) per Common Share minus the applicable Exercise Price per share as of the date of exercise and the denominator of which is the Market Value per share on the date of exercise. Exercise of Warrants shall be for
delivery of Warrant Shares, and under no circumstance shall the Company be obligated to pay or settle exercise of Warrants in cash; provided, however, that the Company may pay cash for fractional interests as set forth in Section 9. Each
Warrant not exercised prior to 5:00 p.m., Hong Kong time, on the Warrant Expiration Date shall become void and all rights thereunder and all rights in respect thereof under this agreement shall cease as of such time. The Warrant Agent shall have
(y) no obligation to calculate the Cashless Exercise Ratio and (z) no responsibility for making any allocation between items (i) – (iii) above. No adjustments as to dividends will be made upon exercise of the Warrants.

 The “Market Value” per Common Share as of any date shall equal (i) if Common Shares are primarily traded on a
securities exchange, the last sale price on such securities exchange on the trading day immediately prior to the date of determination, or if no sale occurred on such day, the mean between the closing “bid” and “asked” prices on
such day, (ii) if the principal market for Common Shares is in the over-the-counter market, the closing sale price on the trading day immediately prior to the date of the determination, as published by the The Nasdaq Stock Market, Inc. or
similar organization, or if such price is not so published on such day, the mean between the closing “bid” and “asked” prices, if available, on such day, which prices may be obtained from any reputable pricing service, broker or
dealer, and (iii) if neither clause (i) nor clause (ii) is applicable, the fair market value on the date of determination of Common Shares, as determined in good faith by the Board of Directors of the Company based on a written
opinion of an internationally recognized investment banking, appraisal or valuation firm that is not an Affiliate of the Company. Notwithstanding the foregoing, if the Market 

  

 10 








 
Value per Common Share is calculated for the purpose of exercising a Warrant on the date of the Qualifying IPO, the Market Value shall be the actual offering
price per Common Share to the public in the Qualifying IPO. 
 (b) In order to exercise all or any of the Warrants represented by a Warrant
Certificate, (i) in the case of a Definitive Warrant, the holder thereof must surrender upon exercise the Warrant Certificate to the Company at the corporate trust office of the Warrant Agent at or before 5:00 p.m., Hong Kong time, on any
Business Day, set forth in Section 15 hereof, (ii) in the case of a book-entry interest in a Global Warrant, the exercising Participant whose name appears on a securities position listing of Euroclear or Clearstream as the holder of
such book-entry interest must comply with Euroclear or Clearstream’s procedures relating to the exercise of such book-entry interest in such Global Warrant and (iii) in the case of interests in both Global Warrants and Definitive Warrants,
the holder thereof or the Participant, as applicable, shall (x) deliver to the Company at the corporate trust office of the Warrant Agent the form of election to purchase on the reverse thereof duly completed and signed, and (y) make
payment to the account of the Company of the applicable Exercise Price in accordance with Section 4(a) hereof, for the number of Warrant Shares in respect of which such Warrants are then exercised and (z) in the event of an exercise
via tendering of Floating Rate Notes pursuant to Section 4(a)(ii) above, surrender the Floating Rate Note or send the relevant instructions to Euroclear or Clearstream, as the case may be. Upon receipt of the executed form of election to
purchase, the Warrant Agent shall promptly, but in no event later than two Business Days following receipt thereof, notify the Company and deliver a copy of such election to purchase form to the Company in accordance with Section 15
hereof. 
 (c) Subject to the provisions of Section 5 hereof, upon compliance with clause (b) above, the Company shall
deliver or cause to be delivered with all reasonable dispatch, to or to 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 hereunder, together with cash as provided in Section 9 hereof; provided that if any consolidation, merger or lease or sale of assets is
proposed to be effected by the Company or its subsidiaries as described in Section 8(k) hereof, or a tender offer or an exchange offer for Common Shares shall be made, upon such surrender of Warrants and payment of the applicable
Exercise Price in accordance with clause (b) above, the Company shall, as soon as possible, but in any event not later than two business days thereafter, deliver or cause to be delivered the full number of Warrant Shares issuable upon the
exercise of such Warrants in the manner described in this sentence or other securities or property to which such holder is entitled hereunder, together with cash as provided in Section 9 hereof and in accordance with the information
provided in the form of election to purchase. The Company shall notify the Warrant Agent the number of Warrant Shares that have been delivered to such holder. Such certificate or certificates 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 as of the date of the surrender of such Warrants and payment of the applicable Exercise Price. 
 (d) The Warrants shall be exercisable, at the election of the holders thereof, either in full or in part from time to time during the Exercise Period. If
less than all the Warrants represented by a Warrant Certificate are exercised, such Warrant Certificate shall be 

  

 11 








 
surrendered and a new Warrant Certificate of the same tenor and for the number of Warrants which were not exercised shall be executed by the Company and
delivered to the Warrant Agent and the Warrant Agent shall countersign the new Warrant Certificate, registered in such name or names as may be directed in writing by the holder, and shall deliver or cause to be delivered the new Warrant Certificate
to the Person or Persons entitled to receive the same. 
 (e) All Warrant Certificates surrendered upon exercise of Warrants shall be
cancelled by the Warrant Agent. Such cancelled Warrant Certificates shall then be disposed of by the Warrant Agent in a manner satisfactory to the Company. The Warrant Agent shall report promptly to the Company with respect to Warrants exercised.

 (f) If the exercising holder fails to pay the applicable Exercise Price to the Company, the Company or the Warrant Agent, as the case may
be, shall be entitled to return or cause to be returned the relevant Warrant Certificates and the form of election to purchase at the expense of such holder. 
 (g) The Warrant Agent shall keep copies of this Agreement and any notices given or received hereunder available for inspection by the holders which shall be allowed upon prior written request with reasonable notice
and during normal business hours at its office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the Warrant Agent may request. 
 SECTION 5. PAYMENT OF TAXES 
 The Company shall pay
all securities transaction taxes and documentary stamp taxes attributable to the initial issuance of Warrant Shares upon the exercise of Warrants; provided that the Company shall not be required to pay any tax or taxes which may be payable in
respect of any transfer involved in the issue of any Warrant Certificates or any certificates for Warrant Shares in a name other than that of the registered holder of a Warrant Certificate surrendered upon the exercise of a Warrant, and the Company
shall not be required to issue or deliver such Warrant Certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid. This provision shall survive the resignation or removal of the Warrant Agent or the termination of this Agreement. 
 SECTION 6. RESERVATION OF WARRANT SHARES 
 (a) The Company shall at all times reserve and keep available, free and clear of
all liens, security interests, charges and other encumbrances or restrictions on sale, free from preemptive rights, out of the aggregate of its authorized but unissued Common Shares or the authorized and issued Common Shares held in its treasury,
for the purpose of enabling it to satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the maximum number of Common Shares which may then be deliverable upon the exercise of all outstanding Warrants. 
 (b) The Company or, if appointed, the transfer agent for the Common Shares (the “Transfer Agent”) and every subsequent transfer
agent for any shares of the Company’s capital stock issuable upon the exercise of any of the rights of purchase aforesaid will be irrevocably authorized and directed at all times to reserve such number of authorized shares as 

  

 12 








 
shall be required for such purpose. The Company shall keep a copy of this Agreement on file with the Transfer Agent and with every subsequent transfer agent
for any shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrants. The Warrant Agent is hereby irrevocably authorized to requisition from time to time from such Transfer Agent the
stock certificates required to honor outstanding Warrants upon exercise thereof in accordance with the terms of this Agreement. The Company shall supply such Transfer Agent with duly executed certificates for such purposes and shall provide or
otherwise make available any cash which may be payable as provided in Section 9 hereof. The Company shall furnish such Transfer Agent with a copy of all notices of adjustments, and certificates related thereto, transmitted to each holder
pursuant to Section 10 hereof. 
 (c) Before taking any action which would cause an adjustment pursuant to Section 8
hereof to reduce the Exercise Price below the then par value (if any) of the Warrant Shares, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue
fully paid and nonassessable Warrant Shares at the Exercise Price as so adjusted. 
 (d) The Company covenants that all Warrant Shares which
may be issued upon exercise of Warrants shall, upon issue, be fully paid, nonassessable, free of preemptive rights and free from all taxes, liens, charges and security interests with respect to the issuance thereof. 
 SECTION 7. OBTAINING STOCK EXCHANGE LISTINGS. 
 The
Company shall from time to time take all action which may be necessary so that the Warrant Shares, immediately upon their issuance upon the exercise of Warrants, will be listed on a principal securities exchange, automated quotation system or other
internationally-recognized stock market on which other Common Shares are then listed, if any and will be freely transferable without any restrictions. 
 SECTION 8. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES ISSUABLE 
 The applicable Exercise Price and the number
of Warrant Shares issuable upon the exercise of each Warrant shall be subject to adjustment from time to time during the Exercise Period upon the occurrence of the events enumerated in this Section 8; provided that in no event
shall the applicable Exercise Price be less than $0.0001 per Common Share. The Company covenants that it will not take any actions that would otherwise result in an adjustment under this Section 8 unless the Warrants may be exercised at
such adjusted Price into legally issued, fully paid and nonassessable Common Shares under applicable law then in effect. For purposes of this Section 8, “Common Shares” includes shares now or hereafter authorized of any
class of common shares of the Company and any other stock of the Company, however designated, that has the right (subject to any prior rights of any class or series of preferred stock) to participate in any distribution of the assets or earnings of
the Company without limit as to per share amount. 
 In addition to the adjustments required under this Section 8, the Company
may, at any time, reduce the applicable Exercise Price to any amount greater than or equal to $0.0001 per share for any period of time (but not less than 20 Business Days if the Common Shares are listed in the U.S.) deemed appropriate by the Board
of Directors of the Company. 
  

 13 








 (a) Adjustment for Change in Capital Stock. 
 If the Company (i) pays a dividend or makes a distribution on its Common Shares payable in its Common Shares, (ii) subdivides its outstanding
Common Shares into a greater number of shares, (iii) combines its outstanding Common Shares into a smaller number of shares, (iv) makes a distribution on its Common Shares in shares of its capital stock other than Common Shares or
(v) issues by reclassification of its Common Shares any shares of its capital stock, then the applicable Exercise Price in effect immediately prior to such action shall, subject to the proviso to the first sentence of the first paragraph of
this Section 8, be proportionately adjusted so that the holder of any Warrant thereafter exercised may receive the aggregate number and kind of shares of capital stock of the Company which such holder would have owned immediately
following such action as if such Warrant had been exercised immediately prior to such action. 
 The adjustment shall become effective
immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification. If, after an adjustment, a holder of a Warrant upon exercise of it
may receive shares of two or more classes of capital stock of the Company, the Company shall determine, in good faith, the allocation of the adjusted Exercise Price between the classes of capital stock. After such allocation, the exercise privilege
and the applicable Exercise Price of each class of capital stock shall thereafter be subject to adjustment on terms comparable to those applicable to Common Shares in this Section 8. Such adjustment shall be made successively whenever
any event listed above shall occur. 
 (b) Adjustment for Rights Issue. 
 If the Company distributes any rights, options or warrants to all holders of its Common Shares entitling them for a period expiring within 45 days after
the record date set forth below to subscribe for Common Shares or securities convertible into, or exchangeable or exercisable for, Common Shares, in either case, at a price per share less than the Market Value per share on that record date, the
applicable Exercise Price shall be adjusted in accordance with the formula: 
  

															
		  		  		  	O	  	+	  	N x P	  		  	
	E’	  	=	  	E	  	x	  	 	  	M	  	 	  	
		  		  		  		  		  	O + N	  		  	

 where: 
  

					
	 E’
	  	=	  	the adjusted Exercise Price.
			
	 E
	  	=	  	the then current Exercise Price.

  

 14 









					
	 O
	  	=	  	the number of Common Shares outstanding on the record date.
			
	 N
	  	=	  	the number of additional Common Shares issued pursuant to such rights, options or warrants.
			
	 P
	  	=	  	the price per share of the additional Common Shares.
			
	 M
	  	=	  	the Market Value per Common Share on the record date.

 The adjustment shall be made successively whenever any such rights, options or warrants are issued
and shall become effective immediately after the record date for the determination of shareholders entitled to receive the rights, options or warrants. If at the end of the period during which such rights, options or warrants are exercisable, not
all rights, options or warrants shall have been exercised, the applicable Exercise Price shall be immediately readjusted to what it would have been if “N” in the above formula had been the number of shares actually issued. 
 (c) Adjustment for Other Distributions. 
 If the Company distributes to all holders of its Common Shares any of its assets (including cash), debt securities, preferred stock or any rights or warrants to purchase assets (including cash), debt securities, preferred stock or other
securities of the Company, the applicable Exercise Price shall be adjusted in accordance with the formula: 
  

											
	 E’
	  	=	  	E	  	x	  	M –F	  	
		  		  		  		  	M	  	

 where: 
  

					
	 E’
	  	=	  	the adjusted Exercise Price.
			
	 E
	  	=	  	the then current Exercise Price.
			
	 M
	  	=	  	the Market Value per Common Share on the record date mentioned below.
			
	 F
	  	=	  	the fair market value on the record date of the debt securities, preferred stock, assets (including cash), securities, rights or warrants to be distributed in respect of one Common Share as
determined in good faith by the Board of Directors of the Company based on a written opinion of an internationally recognized investment banking, appraisal or valuation firm that is not an Affiliate of the Company.

 The adjustment shall be made successively whenever any such distribution is made and shall become
effective immediately after the record date for the determination of shareholders entitled to receive the distribution. 
  

 15 








 This Section 8(c) shall not apply to rights, options or warrants referred to in
Section 8(b) hereof. 
 (d) Adjustment for Common Share Issue. 
 If the Company issues Common Shares for a consideration per share less than the Market Value per share on the date the Company fixes the offering price of
such additional shares, the applicable Exercise Price shall be adjusted in accordance with the formula: 
  

															
		  		  		  		  		  		  	P	  	
	 E’
	  	=	  	E	  	x	  	O	  	+	  	M	  	
		  		  		  		  	A	  		  		  	

 where: 
  

					
	 E’
	  	=	  	the adjusted Exercise Price.
			
	 E
	  	=	  	the then current Exercise Price.
			
	 O
	  	=	  	the number of Common Shares outstanding immediately prior to the issuance of such additional shares.
			
	 P
	  	=	  	the aggregate consideration received for the issuance of such additional shares.
			
	 M
	  	=	  	the Market Value per Common Share on the date of issuance of such additional Common Shares.
			
	 A
	  	=	  	the number of shares outstanding of Common Shares immediately after the issuance of such additional Common Shares.

 The adjustment shall be made successively whenever any such issuance is made, and shall become
effective immediately after such issuance. 
 This subsection (d) shall not apply to: 
 (1) any of the transactions described in subsections (a), (b) or (c) of this Section 8, including, without
limitation, the Common Shares issuable upon the exercise thereof, 
 (2) the exercise of Warrants, or the conversion, exchange
or exercise of other securities convertible into or exchangeable or exercisable for Common Shares the issuance of which requires an adjustment to be made under Section 8(e), 
 (3) the issuance of Common Shares to employees, officers or directors of the Company or its subsidiaries under bona fide employee benefit
plans adopted by the Board of Directors and approved by the holders of Common Shares when required by law, 

  

 16 








 
if such Common Shares would otherwise be covered by this subsection (d) (but only to the extent that the aggregate number of shares excluded hereby and
issued after the date of this Warrant Agreement shall not, together with options exercisable for Common Shares issued under the employee benefit plans referred to Section 8(e)(2), exceed 6,802,495 Common Shares (as adjusted
proportionally for stock dividends, stock splits, combinations, recapitalizations and the like), or 
 (4) the issuance of
Common Shares issuable upon the conversion, exchange or exercise of other securities, warrants, options or similar rights if the conversion, exchange or exercise price is not less than the Market Value per Common Share at the time the security,
warrant, option or right so converted, exchanged or exercised was issued or granted, 
 (5) the issuance of Common Shares in
connection with the exercise by each of Burnhan Securities Inc. and Mr. Joel B. Gardner of those certain warrants to purchase common shares, dated August 25, 2006, or 
 (6) the conversion of the Company’s currently issued and outstanding Series A Preferred Shares into Common Shares. 
 (e) Adjustment for Convertible Securities Issue. 
 If the Company issues any securities convertible into or exchangeable or exercisable for Common Shares (other than securities issued in transactions described in subsections (a), (b) or (c) of this
Section 8) for a consideration per Common Share initially deliverable upon conversion, exchange or exercise of such securities less than the Market Value per share on the date of issuance of such securities or on the date the Company
fixes the offering price of such securities, the applicable Exercise Price shall be adjusted in accordance with the formula: 
  

															
		  		  		  		  		  		  	P	  	
	 E’
	  	=	  	E	  	x	  	O	  	+	  	M	  	
		  		  		  		  	O	  	+	  	D	  	

 where: 
  

					
	E’	  	=	  	the adjusted Exercise Price.
			
	E	  	=	  	the then current Exercise Price.
			
	O	  	=	  	the number of Common Shares outstanding immediately prior to the issuance of such securities.
			
	P	  	=	  	the aggregate consideration received for the issuance of such securities.
			
	 M
	  	=	  	the Market Value per Common Share on the date of issuance of such securities.
			
	 D
	  	=	  	the maximum number of Common Shares deliverable upon conversion or in exchange for such securities at the initial conversion, exchange or exercise rate.

  

 17 








 The adjustment shall be made successively whenever any such issuance is made, and shall become effective
immediately after such issuance. 
 If all of the Common Shares deliverable upon conversion, exchange or exercise of such securities have not
been issued when such securities are no longer outstanding, then the applicable Exercise Price shall promptly be readjusted to the applicable Exercise Price which would then be in effect had the adjustment upon the issuance of such securities been
made on the basis of the actual number of Common Shares issued upon conversion, exchange or exercise of such securities. 
 This subsection
(e) shall not apply to: 
 (1) convertible securities issued to shareholders of any Person which merges into the Company, or with a
subsidiary of the Company, in proportion to their stock holdings of such person immediately prior to such merger, upon such merger, provided that if such Person is an Affiliate of the Company, the Board of Directors shall have obtained a
fairness opinion from a internationally recognized investment banking, appraisal or valuation firm, which is not an Affiliate of the Company, stating that the consideration received in such merger is fair to the Company from a financial point of
view, or 
 (2) the issuance of options exercisable for Common Shares to employees, officers or directors of the Company or its subsidiaries
under bona fide employee benefit plans adopted by the Board of Directors and approved by the holders of Common Shares when required by law, if such Common Shares would otherwise be covered by this subsection (e) (but only to the extent that the
aggregate number of shares excluded hereby and issued after the date of this Warrant Agreement shall not, together with Common Shares issued under the employee benefit plans referred to Section 8(d)(3), exceed 6,802,495 Common Shares (as
adjusted proportionally for stock dividends, stock splits, combinations, recapitalizations and the like). 
 (f) Consideration
Received. 
 For purposes of any computation respecting consideration received pursuant to subsections (d) and (e) of this
Section 8, the following shall apply: 
 (1) in the case of the issuance of Common Shares for cash, the
consideration shall be the amount of such cash, provided that in no case shall any deduction be made for any commissions, discounts or other expenses incurred by the Company for any underwriting of the issue or otherwise in connection
therewith; 
 (2) in the case of the issuance of Common Shares for a consideration in whole or in part other than cash, the
consideration other than cash shall be deemed to 

  

 18 








 
be the fair market value thereof as determined in good faith by the Board of Directors based on a written opinion of an internationally recognized investment
banking, appraisal or valuation firm that is not an Affiliate of the Company (irrespective of the accounting treatment thereof), whose determination shall be conclusive, and described in a Board resolution which shall be filed with the Warrant
Agent; 
 (3) in the case of the issuance of securities convertible into or exchangeable or exercisable for Common Shares, the
aggregate consideration received therefor shall be deemed to be the consideration received by the Company for the issuance of such securities plus the additional minimum consideration, if any, to be received by the Company upon the conversion,
exchange or exercise thereof (the consideration in each case to be determined in the same manner as provided in clauses (1) and (2) of this subsection (f)); and 
 (4) in the case of the issuance of Common Shares pursuant to rights, options or warrants which rights, options or warrants were originally
issued together with one or more other securities as part of a unit at a price per unit, the consideration shall be deemed to be the fair value of such rights, options or warrants at the time of issuance thereof as determined in good faith by the
Board of Directors based on a written opinion of an internationally recognized investment banking, appraisal or valuation firm that is not an Affiliate of the Company and in accordance with GAAP whose determination shall be conclusive and described
in a Board resolution, which shall be filed with the Warrant Agent, plus the additional minimum consideration, if any, to be received by the Company upon the exercise, conversion or exchange thereof (as determined in the same manner as provided in
clauses (1) and (2) of this subsection (f)). 
 (g) When De Minimis Adjustment May Be Deferred. 
 No adjustment in the applicable Exercise Price need be made unless the adjustment would require an increase or decrease of at least 1% in the applicable
Exercise Price. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 8 shall be made by the Company to the nearest cent or to the nearest
1/100th of a share, as the case may be, it being understood that no such rounding shall be made under subsection (o). 
 (h) When No
Adjustment Required. 
 No adjustment need be made for (i) rights to purchase Common Shares pursuant to a Company plan for
reinvestment of dividends or interest or (ii) a change in the par value or no par value of the Common Shares. 
 (i) Notice of
Adjustment. 
 Whenever the applicable Exercise Price is adjusted, the Company shall provide the notices required by
Section 10 hereof. 
  

 19 








 (j) Reorganization of Company. 
 (1) If the Company consolidates or merges with or into, or transfers or leases all or substantially all its assets to, any Person, upon
consummation of such transaction the Warrants shall automatically become exercisable for the kind and amount of securities, cash or other assets which the holder of a Warrant would have owned immediately after the consolidation, merger, transfer or
lease if the holder had exercised the Warrant immediately before the effective date of the transaction. Concurrently with the consummation of such transaction, the corporation formed by or surviving any such consolidation or merger if other than the
Company, or the Person to which such sale or conveyance shall have been made, shall enter into (i) a supplemental Warrant Agreement so providing and further providing for adjustments which shall be as nearly equivalent as may be practical to
the adjustments provided for in this Section 8 and (ii) a supplement to the Equity Registration Rights Agreement providing for the assumption of the Company’s obligations thereunder. The successor company shall mail to Warrant
holders a notice describing the supplemental Warrant Agreement and Equity Registration Rights Agreement. If the issuer of securities deliverable upon exercise of Warrants under the supplemental Warrant Agreement is an Affiliate of the formed,
surviving, transferee or lessee corporation, such issuer shall join in the supplemental Warrant Agreement and Equity Registration Rights Agreement. If this Section 8(j) shall be applicable, Sections 8(a), (b), (c),
(d), (e) and (f) hereof shall not be applicable to such consolidation, merger, transfer or lease. 
 (2) Notwithstanding subclause (1) above, if (A) the Company consolidates or merges with or into, or sells, transfers or leases all or substantially all its assets to, any Person and in connection therewith, the consideration
payable to holders of Common Shares in exchange for their Common Shares is payable solely in cash or (B) proceedings commence for the voluntary or involuntary dissolution, liquidation or winding up of the Company, then the Warrants shall
automatically be exercised into such number of Warrant Shares as is determined pursuant to the provisions of Section 4(a), and the Warrant certificate representing such Warrants shall be deemed cancelled. As a result of such conversion,
each holder of Warrant Shares shall be entitled to receive distributions on an equal basis with the holders of the Common Shares. If this Section 8(j) applies to a transaction, Sections 8(a), (b), (c),
(d) and (e) hereof do not apply to such transaction. 
 (3) This Section 8(j) shall not
apply in the event that the Company merges with another Person and the holders of the Common Shares immediately prior to such merger hold at least a majority of the voting stock of the surviving corporation immediately following the consummation of
such merger. 
 (k) Company Determination Final. 
 Any determination that the Company or the Board of Directors must make pursuant to Section 8(a), (b), (c), (d), (e), (f), (g), or (h) hereof, if made
in good faith, is conclusive. 
  

 20 








 (l) When Issuance or Payment May Be Deferred. 
 In any case in which this Section 8 shall require that an adjustment in the applicable Exercise Price be made effective as of a record date
for a specified event, the Company may elect to defer until the occurrence of such event (i) 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 applicable Exercise Price and (ii) paying to such holder any amount in cash in lieu of a fractional
share pursuant to Section 9 hereof; 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. 
 (m) Adjustment in Number of Shares. 
 Upon each adjustment of the applicable Exercise Price pursuant to this Section 8, each Warrant outstanding prior to the making of the
adjustment in the applicable Exercise Price shall thereafter evidence the right to receive upon payment of the adjusted Exercise Price that number of Common Shares (calculated to the nearest hundredth) obtained from the following formula:

  

											
	 N’
	  	=	  	N	  	x	  	E	  	
		  		  		  		  	E’	  	

 where: 
  

					
	 N’
	  	=	  	the adjusted number of Warrant Shares issuable upon exercise of a Warrant by payment of the adjusted Exercise Price.
			
	 N
	  	=	  	the number or Warrant Shares previously issuable upon exercise of a Warrant by payment of the Exercise Price prior to adjustment.
			
	 E’
	  	=	  	the adjusted Exercise Price.
			
	 E
	  	=	  	the Exercise Price prior to adjustment.

 (n) Form of Warrants. 
 Irrespective of any adjustments in the applicable 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. 
 (o) No Impairment. If any event shall occur as to which the provisions of Section 8 are not strictly applicable but the failure to
make any adjustment would adversely affect the purchase rights represented by the Warrants in accordance with the essential intent and principles of such Section, then, in each such case, the Company shall appoint an investment banking firm of
recognized international standing, or any other financial expert that does not (or whose directors, officers, employees, or affiliates do not) have a direct or material indirect 

  

 21 








 
financial interest in the Company or any of its subsidiaries, who has not been, and, at the time it is called upon to given independent financial advice to
the Company, is not (and none of its directors, officers, employees or affiliates) are a promoter, director or officer of the Company or any of its subsidiaries, which shall give their opinion upon the adjustment, if any, on a basis consistent with
the essential intent and principles established in Section 8 necessary to preserve, without dilution, the purchase rights represented by the Warrants. Upon receipt of such opinion, the Company will promptly deliver a copy thereof to the
Warrant Agent and shall make the adjustments described therein. 
 SECTION 9. FRACTIONAL INTERESTS 
 The Company shall not be required to issue fractional Warrant 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 purchasable on exercise of the Warrants so
presented. If any fraction of a Warrant Share would, except for the provisions of this Section 9, be issuable on the exercise of any Warrants (or specified portion thereof), the Company shall pay an amount in cash equal to the Fair Value
per Warrant Share, as determined on the day immediately preceding the date the Warrant is presented for exercise, multiplied by such fraction, computed to the nearest whole U.S. cent. 
 SECTION 10. NOTICES TO WARRANT HOLDERS 
 (a) Upon any adjustment of the applicable Exercise Price
pursuant to Section 8 hereof, the Company shall promptly thereafter (i) cause to be filed with the Warrant Agent a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors of
the Company (who may be the regular auditors of the Company) setting forth the applicable 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) issuable after such adjustment in the applicable Exercise Price, upon exercise of a Warrant and payment of the adjusted Exercise Price, which certificate shall be conclusive evidence of
the correctness of the matters set forth therein, and (ii) cause to be given to each of the registered holders of Warrants at the address appearing on the Warrant register for each such registered holder 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 10. 
 (b) In the event: 
 (i) that
the Company shall authorize the issuance to all holders of Common Shares of rights, options or warrants to subscribe for or purchase Common Shares or of any other subscription rights or warrants; 
 (ii) that the Company shall authorize the distribution to all holders of Common Shares of evidences of its indebtedness or assets (other
than dividends payable in Common Shares or distributions referred to in Section 8(a) hereof); 
  

 22 








 (iii) of any consolidation or merger to which the Company is a party and for which
approval of any shareholders of the Company is required, or of the conveyance, lease or transfer of all or substantially all of the Company’s properties and assets, or of any reclassification or change of Common Shares 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 Common Shares; 
 (iv) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or 
 (v) that the Company proposes to take any action which would require an adjustment of the applicable Exercise Price pursuant to
Section 8 hereof; 
 then the Company shall cause to be filed with the Warrant Agent and shall cause to be given to each of the registered
holders of Warrants at his address appearing on the Warrant register, at least 20 days (or 10 days in any case specified in clauses (i) or (ii) above) prior to the applicable record date hereinafter specified, 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 Common Shares 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 Common Shares, or (z) the date on which any such consolidation, merger, conveyance, transfer, dissolution, liquidation
or winding up is expected to become effective or consummated, and the date as of which it is expected that holders of record of Common Shares shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such
reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up. The failure to give the notice required by this Section 10 or any defect therein shall not affect the legality or validity of any
distribution, right, option, warrant, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up, or the vote upon any action. 
 (c) Nothing contained in this Agreement or in any of the Warrant Certificates shall be construed as conferring upon the holders of Warrants the right to vote or to consent or to receive notice as shareholders in
respect of the meetings of shareholders or the election of directors of the Company or any other matter, or any rights whatsoever as shareholders of the Company. 
 SECTION 11. MERGER, CONSOLIDATION OR CHANGE OF NAME OF WARRANT AGENT 
 (a) Any corporation into which the Warrant Agent may
be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Warrant Agent, shall be the successor to such Warrant Agent hereunder without the execution or filing of any papers or any further act on the part of any of the parties hereto; provided that such corporation
would have a combined capital and surplus of at least $50.0 million (or would be a wholly-owned subsidiary of a bank or trust company, or of a bank holding company, the principal subsidiary of which is a bank or trust company having a combined
capital and surplus of at least $50.0 million) as set forth in its most recent published annual report of condition. 
  

 23 








 (b) In case at any time the name of the Warrant Agent shall be changed and at such time any of the
Warrant Certificates shall have been countersigned but not delivered, the Warrant Agent whose name has been changed may adopt the countersignature under its prior name, and in case at that time any of the Warrant Certificates shall not have been
countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name, and in all such cases such Warrant Certificates shall have the full force and effect provided in the Warrant Certificates and
in this Agreement. 
 SECTION 12. WARRANT AGENT 
 The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Warrants, by their acceptance thereof, shall be bound: 
 (a) The Warrant Agent shall be obligated to perform such duties and only such duties as are set out in this Agreement and no implied duties or obligations
shall be read into this Agreement against the Warrant Agent. Notwithstanding anything to the contrary contained in this Agreement, the Warrant Agent shall not be obliged to act or omit to act in accordance with any instruction, direction or request
delivered to it by the Company unless such instruction, direction or request is delivered to the Warrant Agent in writing. The Warrant Agent may, in connection with its services hereunder rely upon the terms of any notice, communication or other
document believed by it to be genuine. 
 (b) The Warrant Agent may rely upon and shall not be liable for acting or refraining from acting
upon any written notice, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties. The Warrant Agent shall be under no duty to inquire into or investigate
the validity, accuracy or content of any such document. 
 (c) 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 Warrant Certificates to be complied with by the Company. 
 (d) The
Warrant Agent may engage and consult at the expense of the Company with any legal adviser and professional adviser selected by it and rely upon any advice so obtained and the Warrant Agent and its respective directors, officers, employees and duly
appointed agents shall be protected and shall not be liable in respect of any action taken, or omitted to be done or suffered to be taken, in accordance with such advice. 
 (e) The Warrant Agent shall incur no liability or responsibility to the Company or to any holder of any Warrant Certificate for any action taken in reliance on any Warrant Certificate, certificate of shares, notice,
resolution, waiver, consent, order, certificate, or other paper, document or instrument believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. 
  

 24 








 (f) The Company agrees to pay to the Warrant Agent compensation for all services rendered by the Warrant
Agent in the execution of this Agreement, to reimburse the Warrant Agent for all expenses, taxes and governmental charges and other charges of any kind and nature incurred by the Warrant Agent in the execution of this Agreement. At the request of

Expiration Date entitling the holder on exercise to receive Common Shares, and are issued or to be issued pursuant to a Warrant Agreement dated as of April 13, 2007 (the “Warrant Agreement”), duly executed and delivered

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. Capitalized terms used but not defined herein have the meaning ascribed to such terms in the Warrant Agreement. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the
Company. 
 Warrants may be exercised at any time during the Exercise Period. In order to exercise all or any of the Warrants represented by
this Warrant Certificate, the holder must deliver to the Warrant Agent at its corporate trust office set forth in Section 15 of the Warrant Agreement this Warrant Certificate and the form of election to purchase on the reverse hereof duly
completed and signed, and upon payment to the account of the Company of the Exercise Price, for the number of Warrant Shares in respect of which such Warrants are then exercised. No adjustment shall be made for any dividends on any Common Shares
issuable upon exercise of this Warrant. 
 The Warrant Agreement provides that upon the occurrence of certain events the Exercise Price set
forth on the face hereof may, subject to certain conditions, be adjusted. If the Exercise Price is adjusted, the Warrant Agreement provides that the number of Common Shares issuable upon the exercise of each Warrant shall be adjusted. No fractions
of an Common Share 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. 
 The Company has agreed pursuant to an Equity Registration Rights Agreement dated as of April 13, 2007 to, as promptly as practicable upon the request of a certain number of holders of the Company’s
securities, file a registration statement on an appropriate form under the U.S. Securities Act of 1933 (the “Securities Act”) covering the resale of the Warrant Shares. The Company will use its reasonable efforts to cause any
such registration statement to be declared effective and to keep such registration statement continuously effective under the Securities Act in order to permit the resale of the Warrant Shares by the holders thereof until the Warrant Shares
(i) have been sold pursuant thereto or (ii) may be sold without volume limitations pursuant to Rule 144(k). 
 Warrant
Certificates, when surrendered at the corporate trust office of the Warrant Agent by the registered holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the
limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the
limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 
 The Company and the Warrant Agent may deem and treat the registered holder(s) thereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), 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. Neither the Warrants nor this Warrant Certificate

 This Agreement and each Warrant Certificate issued hereunder
shall be deemed to be a contract made under the laws of the State of New York and for all purposes shall be construed in accordance with the internal laws of said State. 
 The Company agrees that any suit, action or proceeding against it arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State or U.S. federal court in The City of
