 Exhibit 4.5 
 BCD SEMICONDUCTOR MANUFACTURING LIMITED 
 AMENDED AND RESTATED WARRANT TO
PURCHASE SHARES 
 Dated as of             , 2010

  

			
	Warrant No.             	 	Originally Issued: April 27, 2004

 Warrant
to Purchase:                      Warrant Shares (as defined below) 
 This is to certify that subject to the terms and conditions hereof, for value received,
                     (the “Holder”) or its permitted registered assign, is entitled to purchase from BCD Semiconductor
Manufacturing Limited, a Cayman Islands company (the “Company”), the Warrant Shares (as defined below), at the Exercise Price (as defined below), at any time during the period from April 27, 2004 (the
“Commencement Date”) to the earlier of (i) a Change of Control (as such term is defined in the Second Amended and Restated Investors’ Rights Agreement dated as of September 21, 2009 among the Company and
certain of its members (the “Investors’ Rights Agreement”) involving solely cash and/or securities of a successor entity which are then listed on the NASDAQ Stock Market, the American Stock Exchange, the NYSE or an
internationally recognized stock exchange (approved by holders of a majority of the Series C Preference Shares), where the consideration for each Series C Preference Share exceeds $2.50 (as appropriately adjusted for any Recapitalization
(as defined in the Investors’ Rights Agreement)) or (ii) 5:00 p.m. California time on April 27, 2014, such earlier day being referred to herein as the “Expiration Date”. The Company shall give Holder thirty
(30) days advance written notice of the occurrence of a Change of Control. 
 The following terms shall apply to this
Warrant: 
 1.        Warrant Shares; Exercise Price; Exercise of Warrant:
Reservation of Shares. 
 1.1        The shares of capital of the Company which the
Holder may purchase in accordance herewith (the “Warrant Shares”) shall be Series C Preference Shares (“Preference Shares”). Notwithstanding the foregoing, in the event of an IPO (as defined in the
Third Amended and Restated Articles of Association of the Company, as amended), immediately prior to the closing of the IPO and thereafter, the “Warrant Shares” shall mean Ordinary Shares of the Company (“Ordinary
Shares”) and the Warrant shall no longer be exercisable for Preference Shares. The number of Warrant Shares shall be
                     for so long as the Warrant is exercisable for Preference Shares and
                     thereafter. 
 1.2        The per-share price at which the Holder may purchase the Warrant Shares in accordance herewith (the “Exercise Price”) shall be
$2.50 per Preference Share; provided, however, in the event of an IPO, the Exercise Price shall be reduced to $2.00 per Ordinary Share immediately prior to the closing of the IPO, as applicable. 

 1.3        Subject to the terms and conditions
hereof and applicable securities law, this Warrant may be exercised in whole or in part at any time and from time to time on or after the Commencement Date and before the Expiration Date (if such day is a day on which federal or state chartered bank
institutions located in the State of California are authorized by law to close, then on the next succeeding day which shall not be such a day), by presentation and surrender hereof to the Company at its principal office or at the office of its
warrant transfer agent, if any, with the purchase form attached hereto as Exhibit A (the “Purchase Form”) duly executed, with alternative No. 1 initialed by the Holder and accompanied by payment, in cash by
wire transfer or certified or official bank check payable to the order of the Company, of the Exercise Price for the number of Warrant Shares specified in such form. If this Warrant should be exercised in part only, the Company will, upon
presentation of this Warrant upon such exercise, execute and deliver a new warrant, dated the date hereof, evidencing the rights of the Holder thereof to purchase the balance of the Warrant Shares purchasable hereunder upon the same terms and
conditions as herein set forth. Upon and as of such receipt of this Warrant and the Purchase Form by the Company at its office, in proper form for exercise and accompanied by payment as herein provided, the Holder shall be allotted and deemed to be
the holder of record of the Warrant Shares issuable upon such exercise, notwithstanding that the register of members of the Company shall then be closed or that certificates representing the Warrant Shares shall not then be actually delivered to the
Holder. 
 1.4        Notwithstanding any provisions herein to the contrary, if the
fair market value of one Warrant Share is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant for cash, the Holder may elect to receive Warrant Shares equal to the value (as determined
below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Purchase Form with alternative No. 2 initialed by the Holder in which event
the Company shall issue to the Holder a number of Warrant Shares computed using the following formula: 
  

			
	X =	 	Y (A-B)
		 	     A

  

							
	Where	  	X	  	=	  	the number of Warrant Shares to be issued to Holder
				
		  	Y	  	=	  	the number of Warrant Shares purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of such
calculation)
				
		  	A	  	=	  	the fair market value of one Company’s Warrant Share (at the date of such calculation).
				
		  	B	  	=	  	Exercise Price (as adjusted to the date of such calculation)

 For purposes of the above calculation, the fair market value of one Warrant Share shall be determined by the Company’s Board of Directors (including a majority of the Preference Share Directors (as
defined in the Investors’ Rights Agreement)) in the good faith exercise of its reasonable business judgment; provided, however, that: 

  
 -2-

 (i)        if the Warrant is exercised in connection
with the IPO, the fair market value per Warrant Share shall be the per share offering price to the public of the Company’s Ordinary Shares in the IPO whether the Company offers Ordinary Shares or American Depositary Shares that represent
Ordinary Shares (“ADSs”), and the Holder may make such exercise effective and contingent upon the closing of the IPO, as applicable; and 
 (ii)        if the Warrant is exercised after the IPO, the fair market value per Warrant Share shall be the average of the closing bid prices of the Ordinary Shares
based on the conversion ratio from ADSs, if any, on the exchange on which the Ordinary Shares or ADSs are listed as published in the Wall Street Journal for the ten (10) trading day period ending two (2) trading days prior to the
date of determination of fair market value. 
 1.5        The Company shall at all
times after the Commencement Date and until immediately prior to the closing of the IPO reserve from the authorized and unissued Series C Preference Shares a sufficient number of shares to provide for allotment and issuance and delivery upon
exercise of this Warrant the number of Warrant Shares as shall be required for issuance and delivery upon exercise of this Warrant, including taking all actions necessary to increase the authorized number of Series C Preference Shares by a
sufficient number of shares in the event the Company does not have a sufficient number of authorized Series C Preference Shares to allot and issue and deliver upon exercise of this Warrant. The Company shall at all times immediately prior to
the closing of the IPO and thereafter reserve from the authorized and unissued Ordinary Shares a sufficient number of shares to provide for allotment and issuance and delivery upon exercise of this Warrant the number of Warrant Shares as shall be
required for issuance and delivery upon exercise of this Warrant, including taking all actions necessary to increase the authorized number of Ordinary Shares by a sufficient number of shares in the event the Company does not have a sufficient number
of authorized Ordinary Shares to allot and issue and deliver upon exercise of this Warrant. 

1.6        In the event of any exercise of the rights represented by this Warrant, the Company
shall within a reasonable time (not to exceed 30 days) deliver to the Holder certificates for the Warrant Shares so exercised for or a copy of the Company’s Register of Members, certified by the Secretary of the Company or counsel to the
Company, showing the Holder’s name and the number of Warrant Shares issued to the Holder, and, unless this Warrant has been fully exercised or has expired, shall within such time issue and deliver to the Holder a new Warrant in like tenor as
this Warrant representing the Warrant Shares with respect to which this Warrant shall not have been exercised. 

1.7        The Company represents that all Warrant Shares which may be issued upon the exercise
of rights represented by this Warrant will, upon exercise of the rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof (other
than taxes with respect to any transfer occurring contemporaneously with such issue). 

1.8        The Company will not, by amendment of its Memorandum of Association or Articles of
Association or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the 

  
 -3-

 
carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder hereof against impairment. 

2.        Fractional Shares. No fractional shares or scrip representing fractional shares
shall be issued upon the exercise of this Warrant. With respect to any fractional shares called for upon exercise hereof, the Company will pay to the Holder an amount in cash equal to such fraction multiplied by the fair market value of a Warrant
Share, as determined in accordance with Section 1.4 of this Warrant. 

3.        Transfer. The Holder of this Warrant agrees not to sell, pledge, distribute,
offer for sale, transfer or otherwise dispose of this Warrant, except upon the conditions specified in this Section 3. The Holder will cause any proposed transferee of the Warrant to agree to take and hold the Warrant subject to the provisions
and upon the conditions specified in this Section 3. 
 3.1        Subject to the
provisions of Section 3 hereof, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of the Warrant with a properly executed assignment form at the principal office of the Company. 

3.2        Until any transfer of this Warrant is made in the warrant register, the Company may
treat the Holder of this warrant as the absolute owner hereof for all purposes. 

3.3        The Company will maintain a register containing the name and address of the Holder of
this Warrant. The Holder may change the Holder’s address as shown on the Warrant register by written notice to the Company requesting such change. 
 3.4        Subject to Section 3, this Warrant is exchangeable, without expense, at the option of the Holder, for other warrants of different denominations
entitling the Holder to purchase in the aggregate the same number of Warrant Shares purchasable on the same terms and conditions, upon presentation at the principal office of the Company or at the office of its warrant transfer agent, if any,
together with a written notice signed by the Holder specifying the names and denominations in which new warrants are to be issued, and may be divided or combined with other warrants which carry the same rights, upon presentation at the principal
office of the Company or at the office of its warrant transfer agent, if any, together with a written notice signed by the Holder specifying the names and denominations in which new warrants are to be issued. 

4.        Decrease in Exercise Price. The Board of Directors of the Company, in its sole
discretion, shall have the right at any time, or from time to time, to decrease the Exercise Price of the Warrant, such reduction of the Exercise Price to be effective for a period or periods to be determined by it, but in no event for a period of
less than 30 calendar days. Any exercise by the Board of Directors of any rights granted in this Section 4 must be preceded by a written notice from the Company to the Holder of the Warrant setting forth the reduction in the Exercise Price and
to the Warrant Agent, which notice shall be mailed at least 30 calendar days prior to the effective date of such decrease in the Exercise Price of the Warrants. Any reduction of the Exercise Price pursuant to provisions of this Section 4 shall
not alter or adjust the number of Preference Shares or other securities issuable upon the exercise of the Warrants (or the number of Ordinary Shares or other 

  
 -4-

 
securities issuable upon conversion of any Preference Shares or other securities issued upon such exercise). 
 5.        Loss, Theft, Destruction or Mutilation of the Warrant. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction
or mutilation of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Warrant, if mutilated, the Company will execute and deliver a new Warrant of like
tenor and date and any such lost, stolen, or destroyed Warrant shall thereupon become void. 

6.        Adjustment of Number of Warrant Shares and Exercise Price. 

6.1        The number of Warrant Shares for which this Warrant may be exercised shall be
increased or reduced in the same proportion as the increase or decrease in the outstanding Preference Shares or Ordinary Shares, as applicable, in the event there is a subdivision or combination of the outstanding Preference Shares or Ordinary
Shares, as applicable, into a larger or smaller number of shares or there is any stock dividend, stock split, reverse stock split or other similar event affecting the number of outstanding Preference Shares or Ordinary Shares, as applicable.

 6.2        If any reclassification of the capital shares of the Company or any
reorganization, consolidation, merger, or any sale, lease, license, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all, of the business and/or assets of the Company (the
“Reclassification Events”) shall be effected in such a way that holders of Preference Shares or Ordinary Shares, as applicable, shall be entitled to receive stock, securities, or other assets or property, then, as a condition
of such Reclassification Event lawful and adequate provisions shall be made whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of, or in addition to, as applicable, the Warrant Shares immediately theretofore
purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities, or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding Preference Shares or Ordinary
Shares, as applicable, equal to the number of Preference Shares or Ordinary Shares, as applicable, immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. In any Reclassification Event, appropriate
provision shall be made with respect to the rights and interests of the Holder of this Warrant to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of Warrant
Shares), shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities, or assets thereafter deliverable upon the exercise hereof. 
 6.3        In the case the Company shall make or issue, or shall fix a record date for the determination of holders of Preference Shares or Ordinary Shares, as
applicable, entitled to receive, a dividend or other distribution that is payable in (a) securities of the Company (other than issuances with respect to which adjustment is made under Section 6.1), or (b) assets (other than cash
dividends paid or payable solely out of retained earnings), then, and in each such case, the Holder, upon exercise of this Warrant at any time after the consummation, effective date or record date of such event, shall receive, in addition to the
Warrant Shares issuable upon such exercise prior to such date, the securities or such other assets of the Company to which the Holder would have been entitled 

  
 -5-

 
upon such date as if the Holder had exercised this Warrant and been noted in the register of members as the holder of Preference Shares or Ordinary Shares, as applicable, on the record date
immediately prior thereto (all subject to further adjustment as provided in this Warrant). 

6.4        If an effective resolution is passed prior to the expiration of the Warrant for the
voluntary winding-up of the Company, then every Holder will be entitled at any time within six weeks after passing of such resolution for the voluntary winding-up of the Company by irrevocable surrender of the Warrant to the Company with the
purchase form(s) duly completed, together with payment of the Exercise Price or surrender of a portion of this Warrant, to elect to be treated as if he had immediately prior to the passing of such resolution exercised the rights represented by such
Warrant to the extent specified in the Warrant whereupon such Holder will be entitled to receive out the assets available in the liquidation of the Company pari passu with the holders of Preference Shares or Ordinary Shares, as applicable,
such sum as would have been received in respect of the Preference Shares or Ordinary Shares, as applicable, to which he have become entitled pursuant to such exercise had they been allotted and issued to the Holder immediately prior to the passing
of such resolution for the voluntary winding-up of the Company. The Company shall give notice to the Holders of the passing of any such resolution within seven days after the passing thereof and such notice will contain a reminder to Holders with
respect to their rights under this paragraph. Subject to the foregoing, if the Company is wound up, all rights which have not been exercised at the commencement of the winding-up will lapse and each Warrant will cease to be valid for any purpose.

 6.5        Whenever the number of the Warrant Shares purchasable upon the exercise
of this Warrant is adjusted as herein provided, the Exercise Price shall be adjusted by multiplying the applicable Exercise Price immediately prior to such adjustment by a fraction, the numerator of which shall be the number of the Warrant Shares
purchasable in exercise of this Warrant immediately prior to such adjustment and the denominator of which shall be the number of the Warrant Shares purchasable immediately after such adjustment. 

6.6        No adjustment in the number of Warrant Shares purchasable hereunder shall be required
unless such adjustment would require an increase or decrease of at least one whole Warrant Share purchasable upon the exercise of each Warrant; provided, however, that any adjustments which by reason of this Section 6.6 are not
required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations shall be made to the nearest one-thousandth of a share. 
 6.7        Upon any adjustment of the Exercise Price, except for the adjustment set forth in Section 1.2 hereof, then and in each such case the Company shall
give written notice thereof, by first class mail, postage prepaid, addressed to the Holder at the address of the Holder as shown on the warrant register, which notice shall state the Exercise Price resulting from such adjustment, setting forth in
reasonable detail the method of calculation and the facts upon which such calculation is based. 

6.8        The issuance of Warrant Shares upon exercise of this Warrant shall be made without
charge to the Holder thereof for any issuance tax in respect thereof; provided, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in
a name other than that of the Holder. 
 7.        Rights of Holder. This Warrant
does not entitle the Holder hereof to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof. The rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the
Company, except to the extent set forth herein. 

  
 -6-

 8.        Representations and Warranties of
Holder. The Holder hereby makes to the Company the representations and warranties set forth in this Section 8: 

8.1        The Holder has substantial experience in evaluating and investing in private
placement transactions of securities in companies similar to the Company, is capable of evaluating the merits and risks of the Holder’s investment in the Company and has the capacity to protect the Holder’s own interests. 

8.2        The Holder understands that no public market now exists or is anticipated to exist
for any of the securities issued by the Company and no one, including the Company, is under any obligation to register the securities of the Company under the United States Securities Act of 1933, as amended. 

8.3        The Holder has had an opportunity to discuss the management, proposed business plan
and financial condition of the Company with the Company’s management. The Holder understands that a purchase of the securities covered hereby involves a high degree of risk, and there can be no assurances the Company’s business objectives
will be obtained. 
 8.4        The Holder has reviewed with the Holder’s own tax
advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Warrant. The Holder has relied solely on such advisors and not on any statements or representations of the Company or any of
its agents (other than the representations and warranties of the Company contained herein and in the Series C Preference Share Purchase Agreement dated as of April 27, 2004). The Holder understands that the Holder (and not the Company)
shall be responsible for the Holder’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Warrant. 
 9.        Warrant Transfer Agent. Any reference in this Warrant to the warrant transfer agent will apply if, and only if, the Company will have advised the
Holder that such an agent has been designated as an agency for the transfer or exercise of this Warrant. 

10.        Governing Law. This Warrant shall be governed by, and shall be construed in
accordance, with the laws of the State of California without reference to its conflict of laws provisions. 

11.        Notices. All notices and other communications required or permitted hereunder
shall be in writing and may be given by hand, messenger, courier, electronic mail or facsimile addressed (i) if to the Holder, at the address specified in the warrant register, (ii) if to the Company, at No. 1600, ZiXing Road,
Shanghai Science Park, 200241, PRC, 200241 (attention: Chief Executive Officer), Fax No. (8621) 2416-2277 or at such other contact details as the Company shall have furnished to Holder in writing, with a copy to Wilson Sonsini
Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304-1050 USA (attention: Carmen Chang), Fax No. (1650) 493-6811. 
 Where a notice is delivered by hand or by messenger, service of the notice shall be deemed to be effected upon delivery. Where a notice is sent by courier, service of the notice shall be deemed to

  
 -7-

 
be effected by delivery of the notice to a courier company, and shall be deemed to have been received on the 3rd day following the day on which the notice was delivered to the courier. Where a
notice is given by electronic mail service shall be deemed to be effected by transmitting the electronic mail to the electronic mail address provided by the intended recipient and shall be deemed to have been received on the same day that it was
sent, and it shall not necessary for the receipt of the electronic mail to be acknowledged by the recipient. Where a notice is sent by facsimile, service of the notice shall be deemed to be effected by properly addressing and sending such notice and
shall be deemed to have been received on the same day that it was transmitted with confirmation of receipt. 

12.        Terms Binding. This Warrant shall be binding upon any successors or assigns of
the Company. By acceptance of this Warrant, the Holder (and each subsequent assignee, transferee or Holder) accepts and agrees to be bound by all the terms and conditions of this Warrant. 

13.        Headings. The headings in this Warrant are for purposes of convenience only,
and shall not be deemed to constitute a part of this Warrant. 
 14.        Amendment
and Restatement of Prior Warrant. The Company and the Holder agree that Warrant No.          originally issued to the Holder on April 27, 2004 is amended, restated and superseded in its
entirety to read as set forth herein.

 Exhibit 4.6 
 THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OR CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY APPLICABLE
STATE LAWS, AND NO INTEREST THEREIN MAY BE SOLD, DISTRIBUTED, ASSIGNED, OFFERED, PLEDGED OR OTHERWISE TRANSFERRED UNLESS (I) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS COVERING ANY SUCH
TRANSACTION OR SUCH TRANSACTION IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND LAWS AND (II) SUCH TRANSFER IS EFFECTED IN ACCORDANCE WITH THE TERMS SET FORTH IN THIS WARRANT. 

[            ] 

BCD SEMICONDUCTOR MANUFACTURING LIMITED 
 WARRANT TO PURCHASE ORDINARY SHARES 
 Subject to the conditions hereinafter
set forth, [        ] (the “Holder”), is entitled to subscribe for and purchase from BCD SEMICONDUCTOR MANUFACTURING LIMITED, a Cayman Islands company (the
“Company”), on or after the expiration of the lock-up period determined by the Company and its underwriters following the effective date of the registration statement of the Company filed under the Act, with respect to the
Company’s initial offering and sale to the public of its equity securities in a bona fide, firm commitment underwritten offering (the “Lock-Up Period”), and on or before the time and date of termination of this Warrant
as hereinafter provided, [        ] Ordinary Shares of the Company (the “Shares”). This Warrant shall be exercisable at a price per Share equal to
US$[        ] (the “Exercise Price”), subject to the provisions and upon the terms and conditions hereinafter set forth. This Warrant, and the rights to purchase the Shares
hereunder, will terminate in accordance with Section 14 hereof. 

1.        Method of Exercise; Payment. 

  (a)      Net Issue Exercise.    To exercise this Warrant, the
Holder shall surrender this Warrant at the principal office of the Company together with the Notice of Exercise. Upon the exercise of the purchase rights represented by this Warrant, in whole or in part, the Holder shall receive the Shares in an
amount equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) (“Net Issuance”). If the Warrant is exercised in part only, the Company will, upon exercise, execute and deliver a new
Warrant, dated the date hereof evidencing the rights of the Holder thereof to purchase the balance of the Shares purchasable hereunder upon the same terms and conditions set forth herein. In the event the Holder elects to exercise this Warrant
pursuant to the terms hereof, the Company shall issue to the Holder a number of Shares computed using the following formula: 

  

							
		  	X	  	=	  	 Y (A-B)

      A

				
	Where	  	X	  	=	  	the number of Shares to be issued to the Holder.
				
		  	Y	  	=	  	the number of Shares requested to be exercised under this Warrant.
				
		  	A	  	=	  	the fair market value of one Share of the Company.
				
		  	B	  	=	  	The Exercise Price (as adjusted to the date of such calculation).

   (b)      Fair Market Value.    For purposes of this Section 1 and of Section 2 below, the fair market value of the Shares
shall be the price per share as determined by the Company’s Board of Directors (the “Board”) in the good faith exercise of its reasonable business judgment; provided, however, that where there exists an
active public market for the Ordinary Shares of the Company at the time of Net Issuance (as determined by the Board in the good faith exercise of its reasonable business judgment), fair market value shall mean the average over the preceding twenty
(20) trading days (or such fewer number of days the Ordinary Shares have been so traded) of the closing bid and asked prices on the over-the-counter market as published in The Wall Street Journal or any other source as the Board deems reliable,
or if then traded on a national securities exchange including, but not limited to, The Nasdaq Stock Market, the average over the preceding twenty (20) trading days (or such fewer number of days as the Ordinary Shares have been so traded) of the
high and low prices on the principal national securities exchange on which it is so traded as quoted on such exchange. 

  (c)      Share Certificates.    In the event of any exercise of the
rights represented by this Warrant, the Company shall within a reasonable time deliver to the Holder certificates for the Shares so purchased and, unless this Warrant has been fully exercised or has expired, shall within such time issue and deliver
to the Holder a new Warrant in like tenor as this Warrant representing the Shares with respect to which this Warrant shall not have been exercised. 
   (d)      Shares Fully Paid.    The Company covenants that all Shares which may be issued upon the exercise of rights represented by
this Warrant will, upon exercise of the rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof (other than taxes with respect
to any transfer occurring contemporaneously with such issue). 
 2.        No
Fractional Shares or Scrip.    No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. With respect to any fractional shares called for upon exercise hereof, the Company
will pay to the Holder an amount equal to such fraction multiplied by the fair market value of one Share, as determined in accordance with Section 1(b) hereof. 
 3.        Charges, Taxes and Expenses.    Issuance of certificates for the Shares upon the exercise of this Warrant shall be made without
charge to the Holder hereof for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which 

  
 2 

 
taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder of this Warrant or in such name or names as may be directed by the Holder of this
Warrant; provided, however, that upon any transfer involved in the issuance or delivery of any certificates for the Shares, the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax
incidental thereto. 
 4.        No Rights as
Shareholders.    This Warrant does not entitle the Holder hereof to any voting rights or other rights as a shareholder of the Company with respect to the Shares prior to the exercise hereof. The rights of the Holder with
respect to the Shares are limited to those expressed in this Warrant and are not enforceable against the Company, except to the extent as set forth herein. 
 5.        Exchange, Registry and Transfer of Warrant.    This Warrant is exchangeable, upon the surrender hereof by the Holder at the
above-mentioned office or agency of the Company, for a new Warrant of like tenor and dated as of such exchange. The Company shall maintain at the above-mentioned office or agency a registry showing the name and address of the Holder. This Warrant
may be surrendered for exchange, transfer or exercise, in accordance with its terms, at such office or agency of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.
This Warrant, and all rights hereunder are transferable, in whole or in part only upon the prior written consent of the Company, which consent shall not be unreasonably withheld. 

6.        Loss, Theft, Destruction or Mutilation of Warrant.    Upon
receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in case of loss, theft or destruction, of indemnity or security satisfactory to the Company, and upon reimbursement
to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of this Warrant, if mutilated, the Company will make and deliver a new Warrant of like tenor and dated as of such cancellation, in lieu of this
Warrant. 
 7.        Adjustment to Exercise Price and Number of
Shares.    In the event of a share split, share dividend or subdivision of or in respect of the outstanding Ordinary Shares, the number of Shares issuable upon the exercise of this Warrant immediately prior to such share
split, share dividend or subdivision shall be proportionately increased and the Exercise Price then in effect shall be proportionately decreased, effective at the close of business on the record date of such share split, share dividend or
subdivision, as the case may be. In the event of a reverse share split, consolidation, combination or other similar event of or in respect of the outstanding Ordinary Shares, the number of Shares issuable upon the exercise of this Warrant
immediately prior to such reverse share split, consolidation combination or other similar event shall be proportionately decreased and the Exercise Price shall be proportionately increased, effective at the close of business on the record date of
such reverse share split, consolidation, combination or other similar event, as the case may be. 

8.        Certificate as to Adjustments.    In each case of any
adjustment in either the Exercise Price or in the number of Shares, the Company shall compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment and showing in detail the facts upon
which such adjustment is based, including a statement of the 

  
 3 

 
adjusted Exercise Price. The Company will cause a copy of such certificate to be sent to the Holder. 
 9.        Restrictions on Transfer. 
   (a)      Restrictions on Transfer.    The Holder, by acceptance hereof, agrees that, absent an effective registration statement filed
with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Act”), covering the disposition or sale of this Warrant or the Shares issued or issuable upon
exercise hereof, the Holder will not sell or transfer this Warrant, any or all of such Shares or any such other securities, without first providing the Company with an opinion of counsel satisfactory to the Company and its counsel to the effect that
such sale or transfer will be exempt from any registration or prospectus delivery requirements of the Act, and the Holder consents to the Company making a notation in its records, or giving instructions to any transfer agent of this Warrant, or such
Shares, in order to implement such restriction on transfer. As a condition to the transfer of this Warrant or transfer of the Shares issued or issuable upon exercise hereof, any permitted transferee must execute and deliver to the Company
representations and warranties similar to those set forth in Section 10 hereof and agree in writing to accept and be bound by all the terms and conditions of this Warrant. 

  (b)      Restrictive Legends.    Each certificate representing
(i) the Shares issued or issuable upon exercise hereof, and (ii) any other securities issued in respect of the Shares upon any share split, share dividend, recapitalization, merger, consolidation or similar event, shall be stamped or
otherwise imprinted with legends in the following form (in addition to any legend required under any applicable securities laws): 
 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS. SUCH SHARES
MAY NOT BE SOLD, DISTRIBUTED, ASSIGNED, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND LAWS COVERING ANY SUCH TRANSACTION OR UNLESS THE COMPANY RECEIVES AN
OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE COMPANY) SATISFACTORY TO THE COMPANY AND ITS COUNSEL STATING THAT SUCH TRANSACTION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT AND LAWS. 

10.      Representations and Warranties of Holder.    The Holder hereby makes to
the Company the representations and warranties set forth in this Section 10. 

  (a)      Investment.    The Holder is acquiring the Warrant and, if
applicable, the Shares (collectively, the “Securities”) for investment for the Holder’s own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof. The
Holder understands that the Securities to be purchased have not been, registered under the Act by reason of a specific exemption from the registration provisions of the Act, the availability of which depends upon, among other things, the bona fide
nature of the investment intent and the accuracy of the Holder’s representations as expressed herein. 

  
 4 

  (b)      Experience.    The Holder has substantial experience in
evaluating and investing in private placement transactions of securities in companies similar to the Company, is capable of evaluating the merits and risks of the Holder’s investment in the Company and has the capacity to protect the
Holder’s own interests. 
   (c)      Rule 144.    The
Holder acknowledges that the Securities must be held indefinitely unless subsequently registered under the Act or unless an exemption from such registration is available. The Holder is aware of the provisions of Rule 144 promulgated under the Act
(“Rule 144”) which permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things, the existence of a public market for the shares, the
availability of certain current public information about the Company, the resale occurring not less than one year after a party has purchased and paid for the security to be sold, the sale being effected through a “broker’s
transaction” or in transactions directly with a “market maker” and the number of shares being sold during any three-month period not exceeding specified limitations. 

  (d)      No Public Market.    The Holder understands that no public
market now exists or is anticipated to exist for any of the Securities issued by the Company and no one, including the Company, is under any obligation to register the Securities under the Act. 

  (e)      Access to Data.    The Holder has had an opportunity to
discuss the management, proposed business plan and financial condition of the Company with the Company’s management. The Holder understands that a purchase of the Securities involves a high degree of risk, and there can be no assurances the
Company’s business objectives will be obtained. 

  (f)      Authorization.    This Warrant when executed and delivered
by the Holder will constitute a valid and legally binding obligation of the Holder, enforceable in accordance with its terms, except to the extent that such enforcement may be limited by bankruptcy, insolvency or similar laws now or hereafter in
effect relating to creditors’ rights and remedies generally. 
   (g)      Tax
Liability.    The Holder has reviewed with the Holder’s own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Warrant. The Holder has relied
solely on such advisors and not on any statements or representations of the Company or any of its agents. The Holder understands that the Holder (and not the Company) shall be responsible for the Holder’s own tax liability that may arise as a
result of this investment or the transactions contemplated by this Warrant. 

  (h)      Legal Representation.    Wilson Sonsini
Goodrich & Rosati, P.C. is counsel for the Company only and is not acting as counsel for the Holder. The Holder acknowledges that the Holder has been advised to consult with the Holder’s own legal counsel in connection with this
investment. 

  
 5 

   (i)      Regulation S/Non-U.S.
Person.    The Holder hereby represents that the Holder: 

  (i)       is not a “U.S. Person” within the meaning of Rule 902 of Regulation
S, promulgated under the Act, as presently in effect. The term “U.S. Person” includes: (i) any natural person (regardless of citizenship) who resides in the United States; (ii) any partnership or corporation organized or
incorporated under the laws of the United States; (iii) any estate or trust of which any executor, administrator or trustee is a U.S. Person; (iv) any agency or branch of a non-U.S. entity located in the United States; (v) any
non-discretionary account or similar account (other than an estate or trust) held by a dealer or other fiduciary for the benefit or account of a U.S. Person (whether or not the dealer or other fiduciary is a U.S. Person); (vi) any discretionary
account or similar account (other than an estate or trust) held by a dealer or other fiduciary organized, incorporated or (if an individual) resident in the United States; and (vii) a corporation or partnership organized under the laws of any
jurisdiction other than the United States by a U.S. Person principally for the purpose of investing in securities that have not been registered under the Act unless organized or incorporated and owned entirely by accredited investors who are not
natural persons, estates or trusts (as defined in Rule 501(a) under the Act; 

  (ii)      is not acquiring the Warrant and will not acquire the Shares purchasable pursuant to
the terms of the Warrant for the account or benefit of any U.S. Person and, as of the date hereof the Holder, or persons acting on the Holder’s behalf is located outside the United States; 

  (iii)     has satisfied itself as to the full observance of the laws of the Holder’s
jurisdiction in connection with receipt of the Warrant and the Shares purchasable pursuant to the terms of the Warrant or any use of this Warrant, including (A) the legal requirements within the Holder’s jurisdiction for the purchase of
the Warrant and the Shares, (B) any foreign exchange restrictions applicable to such purchase, (C) any governmental or other consents that may need to be obtained, and (D) the income tax and other tax consequences, if any, that may be
relevant to the purchase, holding, redemption, sale, or transfer of the Warrant and the Shares. The Holder’s receipt and continued beneficial ownership of the Warrant and, upon exercise, the Shares, will not violate any applicable securities or
other laws of the Holder’s jurisdiction; and 
   (iv)     has not engaged, nor is the
Holder aware that any party has engaged, and the Holder covenants that the Holder will not engage or cause any third party to engage in any directed selling efforts (as such term is defined in Regulation S) in the United States with respect to the
Shares. 
 11.      Miscellaneous. 

  (a)      Authorized Shares.    The Company covenants that during
the period the Warrant is exercisable, it will reserve from the authorized and unissued Ordinary Shares a sufficient number of shares to provide for the issuance of the Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing 

  
 6 

 
stock certificates to execute and issue the necessary certificates for the Shares upon the exercise of the purchase rights under this Warrant. 

  (b)      Notices of Record Date.     In case 

  (i)      the Company shall take a record of the holders of its Ordinary Shares for the
purposes of entitling them to receive any dividend (other than a cash dividend) or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares or stock of any class or any other securities or property, or to receive
any other right; or 
   (ii)     of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or merger of the Company with or into another corporation, or any conveyance of all or substantially all of the assets of the Company to another corporation; or 

  (iii)    of the voluntary or involuntary dissolution, liquidation or winding up of the Company;

 then, and in each such case, the Company will send or cause to be sent to the Holder a notice specifying, as the case may be, (i) the
date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the date on which such reorganization, reclassification,
consolidation, merger, conveyance, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of the Shares shall be entitled to exchange their Shares for securities or other
property deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding-up. Such notice shall be sent at least ten (10) days prior to the date therein specified. 

12.      Notices.    All notices and other communications required or permitted
hereunder shall be in writing and may be given by hand, messenger, courier, electronic mail or facsimile addressed (i) if to the Holder, at the address specified in the warrant register, (ii) if to the Company, at its principal offices
(attention: Chief Executive Officer) or at such other contact details as the Company shall have furnished to Holder in writing, with a copy to Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304
(attention: Carmen Chang), Fax No. (650) 493-6811. 
 Where a notice is delivered by hand or by
messenger, service of the notice shall be deemed to be effected upon delivery. Where a notice is sent by courier, service of the notice shall be deemed to have been received on the 3rd day following the day on which the notice was delivered to the courier. Where a notice is given by electronic mail,
service shall be deemed to be effected by transmitting the electronic mail to the electronic mail address provided by the intended recipient and shall be deemed to have been received on the same day that it was sent, and it shall not be necessary
for the receipt of the electronic mail to be acknowledged by the recipient. Where a notice is sent by facsimile, service of the notice shall be deemed to be effected by properly addressing and sending such notice and shall be deemed to have been
received on the same day that it was transmitted with confirmation of receipt. 

  
 7 

 13.      Attorneys’
Fees.    In the event any party is required to engage the services of attorneys for the purpose of enforcing this Warrant, or any provision thereof, the prevailing party shall be entitled to recover its reasonable
attorneys’ fees and any other related cost or expenses. 

14.      Termination.    This Warrant (and the right to purchase securities upon
exercise hereof) shall terminate at 5 p.m. (California time) on the date that is six (6) months after the expiration of the Lock-Up Period, if not exercised prior thereto. 

15.      Headings.    The headings in this Warrant are for purposes of
convenience only, and shall not be deemed to constitute a part of this Warrant. 

16.      Governing Law.    This Warrant shall constitute a contract under the
laws of the State of California and shall be construed and enforced in accordance with, and governed by, the internal laws of the State of California, excluding that body of law applicable to conflicts of laws. 

17.      Terms Binding.    This Warrant shall be binding upon any successors or
assigns of the Company. By acceptance of this Warrant, the Holder (and each subsequent assignee, transferee or Holder) accepts and agrees to be bound by all the terms and conditions of this Warrant.
