conversion date, (ii) where the Note (or portion thereof) is prepaid, from the relevant prepayment date unless, upon due presentation, payment of the Principal Amount or accrued interest thereon is improperly withheld or refused, in which event
the Note (or portion thereof) shall continue to bear interest at the then applicable interest rate until payment of the Principal Amount or accrued interest thereon is made in full or (iii) on the Maturity Date, to the extent that the
outstanding Principal Amount of the Note, together with all accrued but unpaid interest thereon, shall have been paid in full by such date. 
  

 8 

 3. Conversion. 
 3.1. Optional Conversion. At any time from and after the earlier of (a) the occurrence of an IPO or (b) following delivery of the Sale Notice and prior to the consummation of a Sale Transaction (the
earlier of such events, the “Triggering Event”), the Holder shall have the right, but not obligation, to convert in whole or in part (the “Conversion Right”) the then outstanding Principal Amount plus all accrued
and unpaid interest thereon to the date of such conversion, into such number of fully paid and non-assessable Ordinary Shares equal to a fraction, the numerator of which is the sum of the Principal Amount to be converted plus all accrued and unpaid
interest to the date of such conversion and the denominator of which is the Conversion Price (as adjusted pursuant to Section 4). No notice delivered by the Company of any proposed redemption or Sale Transaction or other event will limit in any
way any Holder’s right to convert this Note. The Company shall give the Holder at least ten (10) days prior written notice of a Sale Transaction, setting out reasonable details of the terms of the proposed Sale Transaction (the
“Sale Notice”). If the Holder does not convert this Note into Ordinary Shares at any time prior to the consummation of a Sale Transaction, the Principal Amount and all accrued and unpaid interest thereon shall be due and payable on
the date of consummation of such Sale Transaction. 
 3.2. Conversion Price. The initial conversion price shall be (a) in the
event that the Triggering Event is an IPO, equal to the product of 90% multiplied by, in the event of a listing in the US, the final price per share of the Ordinary Shares offered by the Company to the public in the IPO as set forth in the final
prospectus or, in the event of a listing only outside the US, the final listing price per share of the Ordinary Shares on the principal securities exchange on which the Ordinary Shares are listed and (b) in the event that the Triggering Event
is a Sale Transaction, equal to the product of 90% multiplied by the price per share offered for the Ordinary Shares (calculated without taking into account the conversion of this Note) based on the valuation of the Company in such Sale Transaction
(subject to adjustment as provided in Sections 4.1, 4.2 and 4.3 below, the “Conversion Price”); provided, however, that notwithstanding the foregoing, if the calculation of the initial Conversion Price pursuant to the
foregoing clause (a) or clause (b), as the case may be, is greater than US$86.872 (subject to adjustment for share splits, share dividends, bonus issues, reorganizations, recapitalizations or similar events) (the “Maximum Conversion
Price”), then the initial Conversion Price shall equal the Maximum Conversion Price. 
 3.3. Conversion Procedures. The
Conversion Right shall be exercised by the surrender by the Holder of this Note, accompanied by written notice to the Company at its principal corporate office (the “Conversion Notice”) specifying (a) that the Holder elects to
convert this Note in whole or in part, and if in part, the Principal Amount of this Note to be converted and (b) the name or names (with address) in which a certificate or certificates for Ordinary Shares are to be issued. This Note shall be
canceled upon issuance of the Ordinary Shares. As soon as practicable after the delivery of the Conversion Notice, but in no event later than five Business Days thereafter, the Company shall (i) take all actions and execute all documents
necessary to effect the issuance and registration of such Ordinary Shares on the share registry of the Company (including giving all necessary instruction to the relevant share registry to effect such issuance and registration) and (ii) deliver
to the Holder (x) certificate(s) representing the number of 

  

 9 

 
fully paid and non-assessable Ordinary Shares calculated in accordance with Section 3.2 (and to the extent that only a portion of this Note is
converted, a replacement Note reflecting the remaining outstanding Principal Amount), bearing such legends as are required by applicable securities laws in the written opinion of counsel to the Company, and (y) any other securities and property
to which the Holder is entitled upon such conversion under the terms of this Note, including a check payable to the Holder for any cash amounts as described in Section 3.4. 
 3.4. Mechanics and Effect of Conversion. No fractional shares Ordinary Share shall be issued upon conversion of this Note. In lieu of the Company
issuing any fractional shares to Holder upon the conversion of this Note, the Company shall pay to Holder the amount of outstanding principal and interest that is not so converted. Upon conversion of all amounts due under this Note, the Company
shall be forever released from all of its obligations and liabilities under this Note. 
 3.5. Availability of Shares. The Company
covenants that it will at all times reserve and maintain authority to issue, solely for the purpose of issue or delivery upon any conversion herein provided, the maximum number of Ordinary Shares that may be, in the Company’s reasonable
judgment, issuable upon conversion of this Note. The Company covenants that all Ordinary Shares, when issued or delivered pursuant to Section 3.3, shall be duly and validly issued and fully paid, free and clear of all Liens. 
 4. Anti-dilution Adjustments. The Conversion Price, and the number and type of securities to be received upon conversion of this Note, shall be
subject to adjustment as follows: 
 4.1. Dividend, Subdivision, Combination, Share Split, Recapitalization or Reclassification of
Ordinary Shares. In the event that the Company shall at any time or from time to time prior to the conversion or payment of this Note, effect a subdivision or combination of its outstanding Ordinary Shares or in the event of a reclassification,
recapitalization, share split, share combination, bonus issue or other distribution payable in securities of the Company or any other Person, then, and in each such case, the Conversion Price in effect immediately prior to such event shall be
proportionally adjusted (and any other appropriate actions shall be taken by the Company) so that the Holder shall be entitled to receive the number of Ordinary Shares or other securities of the Company that the Holder would have owned or would have
been entitled to receive upon or by reason of any of the events described above, had this Note been converted immediately prior to the occurrence of such event. An adjustment made pursuant to this Section 4.1 shall become effective
retroactively (x) in the case of any such dividend or distribution, to a date immediately following the close of business on the record date for the determination of holders of Ordinary Shares entitled to receive such dividend or distribution
or (y) in the case of any such subdivision, combination, reclassification, recapitalization or share split, to the close of business on the day upon which such corporate action becomes effective. 
  

 10 

 4.2. Issuances below Current Market Price. If and whenever the Company shall issue (other than
Excluded Securities) any Ordinary Shares or if and whenever the Company shall issue or grant (other than Excluded Securities) options, warrants or other rights to subscribe or purchase shares (including securities that are convertible into Ordinary
Shares), in each case, at a price per share which is less than the Current Market Price on the last Trading Day preceding the day of announcement of the terms of such issue or grant, the Conversion Price shall be adjusted by multiplying the
Conversion Price in force immediately before such issue or grant by the following fraction; 
 A+B  
    C   
 where:

  

	 	A	shall mean the number of Ordinary Shares in issue immediately before the issue of such additional Ordinary Shares or the grant of such options, warrants or other rights to subscribe
for or purchase any Ordinary Shares; 

  

	 	B	shall mean the number of Ordinary Shares which the aggregate consideration receivable by the Company for the issue of such additional Ordinary Shares would purchase at such Current
Market Price per Ordinary Share; and 

  

	 	C	shall mean the number of Ordinary Shares in issue immediately after the issue of such additional Ordinary Shares. 

 References to additional Ordinary Shares in the above formula shall, in the case of an issue or grant by the Company of options, warrants or other rights to subscribe or
purchase Ordinary Shares, mean such Ordinary Shares to be issued, or otherwise made available, assuming that such options, warrants or other rights are exercised in full at the initial exercise price (if applicable) or the date of issue or grant of
such options, warrants or other rights. 
 Such adjustment shall become effective on the date of issue of such additional Ordinary Shares or, as the case may
be, the issue or grant of such options, warrants or other rights. 
 4.3. Capital Distribution. If at any time from and after the
occurrence of a Triggering Event, the Company shall pay or make any Capital Distribution to its shareholders, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such Capital Distribution by the
following fraction: 
 A-B  
   A   
  

 11 

 where: 
 A shall mean the Current Market Price of one Ordinary Share on the last business day preceding the date of the Capital Distribution is publicly announced; and 
 B shall mean the Fair Market Value on the date of such announcement, immediately after the Capital Distribution, of the portion of the Capital
Distribution attributable to one Ordinary Share. 
 Such adjustment shall become effective on the date that such Capital Distribution is
made. 
 4.4. Other Changes. If the Company at any time or from time to time, prior to the conversion of this Note, shall take any
action affecting its Ordinary Shares or share capital similar to or having an effect similar to any of the actions described in Sections 4.1 or 4.2, then, and in each such case, the Conversion Price shall be adjusted in such manner as would be
equitable in the circumstances. 
 4.5. Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment
pursuant to this Section 4, the Company at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to Holder a certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based. 
 4.6. No Impairment. The Company will not, by any voluntary
action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Section 4 and in
the taking of all such action as may be necessary or appropriate in order to protect the rights of Holder against impairment. 
 5. Put
Option. 
 5.1. General. If the Company does not consummate a Qualifying IPO prior to January 1, 2008 then, from and after
the earlier of (x) January 1, 2008 and (y) the date upon which an IPO that is not a Qualifying IPO is consummated, the Holder shall have the right, at its option, to require the Company to repurchase this Note (the “Put
Option”) from the Holder for an aggregate purchase price in cash (the “Put Price”) equal to (i) the aggregate initial Principal Amount (excluding any interest added thereto pursuant to Section 2), plus
(ii) an amount representing a 12% Internal Rate of Return (which, for the avoidance of doubt, shall be inclusive of all accrued and unpaid interest on the initial Principal Amount that has accrued in the manner set forth in Section 2) on
the initial Principal Amount (excluding any interest added thereto pursuant to Section 2), calculated from the date hereof through and until the date of payment in full of the Put Price (the “Redemption Date”). 
 5.2. Put Option Procedures. The Holder may exercise the Put Option under Section 5.1 by delivering written notice to the Company (the
“Put Option Notice”). The Company shall pay the Holder the Put Price not later than twenty (20) Business Days 

  

 12 

 
after delivery of such Put Option Notice by the Holder, and this Note shall be cancelled and retired. If the Put Option Notice shall have been duly given,
and if on the Redemption Date the Put Price payable upon repurchase of this Note on the Redemption Date is paid or tendered for payment or deposited with an independent payment agent so as to be available therefor, then notwithstanding that this
Note shall not have been surrendered by the Holder, interest with respect to this Note shall cease to accrue after the Redemption Date and all rights with respect to this Note (other than the right to receive the Put Price) shall forthwith after the
Redemption Date terminate. 
 5.3. Failure to Pay. In the event that the Holder exercises the Put Option and the Company does not
have sufficient funds to pay the Put Price in full, this Note and the then outstanding Principal Amount plus all accrued and unpaid interest thereon shall, notwithstanding the Holder’s surrender of the Note to the Company pursuant to
Section 5.2, remain outstanding until the date the Holder receives the Put Price in full and the Holder shall maintain all of its rights and remedies under this Note. For the avoidance of doubt, interest on the Principal Amount shall continue
to accrue to the extent provided in Section 2 until the date the Holder receives the Put Price in full. 
 5.4. Delisting Put Right.
 
 (a) At any time after the IPO, if the Ordinary Shares cease to be listed or admitted to trading on any stock exchange (a
“Delisting”), the Holder shall have the right (the “Delisting Put Right”), at such Holder’s option, to require the Company to redeem all (but not less than all) of this Note on the date (the “Delisting
Put Date”) that is 20 Business Days after notice has been given to the Holders regarding the Delisting referred to under this Section 5.4 or, if such notice is not given, 20 Business Days after the Delisting for an aggregate purchase
price in cash, equal to the Early Redemption Amount. 
 (b) Within five Business Days after becoming aware of a Delisting, the Company shall
procure that written notice regarding the Delisting Put Right shall be given to the Holder in accordance with Section 19, specifying: 
 (i) the date of such Delisting and, in reasonable detail, the events causing such Delisting; 
 (ii) the date by which the Purchase
Notice must be given; 
 (iii) the applicable Early Redemption Amount; 
 (iv) that a Purchase Notice, once validly given, may not be withdrawn; 
 (v) the Closing Price of the Ordinary Shares as at the latest practicable date prior to the publication of such notice regarding the Delisting Put Right; and 
  

 13 

 (vi) the aggregate principal amount of the Notes outstanding as at the latest practicable date prior to
the publication of such notice regarding the Delisting Put Right. 
 (c) To exercise the Delisting Put Right, the Holder must deliver a
written irrevocable notice of the exercise (a “Purchase Notice”) to the Company on any Business Day prior to the close of business on such day which is not less than 10 Business Days prior to the Delisting Put Date. 
 (d) A Purchase Notice, once delivered, shall be irrevocable and the Company shall redeem the Notes which form the subject of the Purchase Notice
delivered as aforesaid on the Delisting Put Date. 
 6. Call Option 
 6.1. General. 
 (a) If the Company
consummates an IPO that is not a Qualifying IPO, then the Company shall have the right, but not the obligation, to prepay this Note in full and not in part (the “Call Option”) for an aggregate purchase price in cash equal to the sum
of the aggregate Principal Amount, plus all accrued and unpaid interest thereon (the “Prepayment Amount”), at any time after the third anniversary of such IPO (the “Trigger Date”) if the closing price per share for
each of the any 15 trading days falling within a period of 30 consecutive trading days occurring after the Trigger Date, with the last day of such period occurring no more than five trading days prior to the date upon which Prepayment Notice is
given, was for each such 15 trading days at least 140% of the Conversion Price then in effect. 
 (b) Notwithstanding the foregoing, if the
Company does not consummate any IPO (including a Qualifying IPO) on or prior to the third anniversary of the date hereof, then from and after such third anniversary, the Company shall have the right to exercise the Call Option for the aggregate
purchase price equal to the Prepayment Amount. 
 (c) Notwithstanding the foregoing, if the Holder breaches its covenant not to transfer
this Note to a direct competitor and/or customer of the Company, as set forth in Section 14.2 below, the Company shall have the immediate right to exercise the Call Option for the aggregate purchase price equal to the Prepayment Amount.

 (d) Except in the case of Section 6.1(c) above, notwithstanding anything to the contrary set forth in this Section 6, the
Company may not exercise the Call Option unless (i) it exercises the Call Option with respect to all Notes issued under the Note Purchase Agreement and (ii) all of such Notes are simultaneously repurchased in full. 
 6.2. Notice. The Company may exercise the Call Option by delivering written notice to the Holder (the “Prepayment
Notice”), which Notice shall not be effective until the 15th day after such
Prepayment Notice is given (the “Effective Date”). On the 

  

 14 

 
Effective Date, the Company shall pay the Prepayment Amount by wire transfer of immediately available funds to an account designated by the Holder in
writing; provided, however, that notwithstanding the foregoing or anything to the contrary set forth in this Section 6, during the period after the Prepayment Notice is given, but prior to the Effective Date, the Holder shall have
the right, but not the obligation, to (i) convert this Note in the manner set forth in Section 3 or (ii) exercise the Put Option, in which case the Holder shall be paid on the Effective Date the aggregate purchase price equal to the
Put Price and surrender this Note to the Company for cancellation. If the Prepayment Notice shall have been duly given, and if by the Effective Date no account has been designated by a Holder for payment (as contemplated above), then notwithstanding
that this Note shall not have been surrendered by the Holder, interest with respect to this Note shall cease to accrue after the Effective Date and all rights with respect to this Note (other than the right to receive the Prepayment Amount) shall
forthwith after the Effective Date terminate. 
 7. Major Actions. For so long as at least 50% of the initial Principal Amount of all
of the Notes issued pursuant to the Purchase Agreement is outstanding, the Company shall not, and the Company shall not permit any Subsidiary to, take any of the following actions without the prior written consent of the Majority Holders:

 (a) at any time prior to a Qualifying IPO, (i) redeem any equity securities if the amount of such redemptions, when aggregated with
all other redemptions of equity securities during the period from the date hereof to the date of such redemption, exceeds $2,500,000 (excluding any redemption by the Company of (a) the Notes, (b) any equity securities in accordance with
the Joint Venture Agreement (as defined in the Purchase Agreement) or the Amended and Restated Memorandum and Articles of Association adopted by the Company and filed with the Registry of Corporate Affairs in the Territory of the British Virgin
Islands on February [Date], 2007 (the “M&AA”) and (c) any transactions contemplated in the Sellers Agreement (as defined in the Subscription Agreement (as defined in the Purchase Agreement))) or (ii) pay, in whole or
in part, of any Indebtedness (other than all present bank and purchase money loans, equipment financings and equipment leasings); 
 (b) at
any time upon or after a Qualifying IPO, (i) redeem any equity securities if the amount of such redemptions, when aggregated with all other redemptions of equity securities during the period from the date hereof to the date of such redemption,
exceeds $2,500,000 (excluding any redemption by the Company of (a) the Notes, (b) any equity securities in accordance with the Joint Venture Agreement (as defined in the Purchase Agreement) or the M&AA and (c) any transactions
contemplated in the Sellers Agreement (as defined in the Subscription Agreement (as defined in the Purchase Agreement))) or (ii) pay, in whole or in part, of any Indebtedness for borrowed money (other than all present and future bank and
purchase money loans, equipment financings and equipment leasings); 
 (c) declare or pay any dividends or other distributions to any equity
securities (other than the declaration and payment of (i) a cash dividend in any fiscal year which, when aggregated with all other cash dividends declared during such fiscal 

  

 15 

 
year, does not exceed 50% of the Company’s audited consolidated net income for its most recently completed fiscal year, calculated in accordance with
US GAAP or (ii) any dividend for which an adjustment is made in accordance with the terms of this Note); or 
 (d) at any time
prior to an IPO, have outstanding, incur, assume, issue or guarantee any Indebtedness (i) prior to January 1, 2008, in excess of US$18 million in the aggregate for the Company and its Subsidiaries (excluding the $40 million of Indebtedness
incurred pursuant to the Notes) and (ii) from and after January 1, 2008, if the Company’s ratio of total consolidated Indebtedness (excluding cash and cash equivalents) to EBITDA (excluding any share-based compensation expenses
recognized in accordance with US GAAP) as set forth in the Company’s audited consolidated income statement (once available) for its most recently completed fiscal year would exceed 2.5:1 on a pro forma basis, each calculated in accordance with
US GAAP. 
 8. The occurrence of any one or more of the following events shall constitute an “Event of Default”: 

8.1. Failure To Pay. (i) The failure of the Company to pay any Principal Amount due under any of the Notes when due and payable (whether
by acceleration, declaration, extension or otherwise), or (ii) the failure of the Company to pay any interest or other amounts due under any of the Notes when due and payable if such failure is not cured within five (5) Business Days of
Company’s receipt of notice thereof from any of the Holders. 
 8.2. Representations and Warranties. If any of the
representations or warranties made by the Company in (a) Sections 1(c), 1(d), 2, 7 and 11(b) of Schedule 3 of the Purchase Agreement is not true and correct in all material respects, and such breach, if capable of remedy, is not cured within 15
days after written notice of such breach is given to the Company or (b) Sections 4(a), 4(b), 5(a) and 6 of Schedule 3 of the Purchase Agreement is not true and correct (without regard to any “materiality” or “material adverse
effect” qualifications contained in them), and such breach in the case of this clause (b), (I) if capable of remedy, is not cured within 15 days after written notice of such breach is given to the Company and (II) does not or is not
reasonably be expected to have a Material Adverse Effect (as defined in the Purchase Agreement); provided, however, that there shall be no Event of Default under this Section 8.2 if such written notice is delivered to the Company
following the consummation of a Qualifying IPO; and provided further, that notwithstanding the foregoing, if such written notice is delivered to the Company prior to the consummation of a Qualifying IPO, then the Holder may take the
actions described in Section 9 of this Note notwithstanding that the Holder takes such actions after the consummation of the Qualifying IPO. Notwithstanding the foregoing, if any Claims (as defined in the Purchase Agreement) for indemnification
in respect of any Losses (as defined in the Purchase Agreement) have been made pursuant to and in the manner provided in Article VI of the Purchase Agreement with respect to any representation and warranty in the Purchase Agreement prior to the
applicable expiration of any such representation and warranty, then such representation and warranty shall continue in effect until the final resolution of such Claims in accordance with the Purchase Agreement. 
  

 16 

 8.3. Covenants and Agreements. The material breach by the Company in its performance, observance
or compliance with any of its covenants in this Note or Article VI of the Purchase Agreement, where such breach, if capable of remedy, is not cured within 15 days after written notice of such breach is given to the Company. 
 8.4. Default on Other Obligations. The occurrence of any event or condition under any other Indebtedness for borrowed money of the Company or any
of its Subsidiaries with a principal amount of (i) prior to a Qualifying IPO, at least five million dollars (US$5,000,000) or (ii) after a Qualifying IPO, at least fifteen million dollars (US$15,000,000), in each case that results in the
acceleration of the maturity of or default under such Indebtedness for borrowed money, where such acceleration or default, if capable of remedy, is not cured within 15 Business Days after written notice of such acceleration or default is given to
the Company. 
 8.5. Judgments, Awards. One or more final judgments or orders for the payment of money is rendered against the
Company or any of its Subsidiaries in an amount in excess of (i) prior to a Qualifying IPO, five million dollars (US$5,000,000) individually or in the aggregate and (ii) after a Qualifying IPO, fifteen million dollars (US$15,000,000)
individually or in the aggregate, and in each case, the same shall remain undischarged for a period of 30 days. 
 8.6. Involuntary
Bankruptcy. There shall be filed against the Company or any of its Subsidiaries an involuntary petition or other pleading seeking the entry of a decree or order for relief under the United States Bankruptcy Code or any other or similar
insolvency or similar laws of any jurisdiction, ordering (a) the liquidation of the Company or any of its Subsidiaries or (b) a reorganization of the Company or any of its Subsidiaries or the business and affairs of the Company or any of
its Subsidiaries or (c) the appointment of a receiver, liquidator, assignee, custodian, trustee or similar official for the Company or any of its Subsidiaries of the property of the Company or any of its Subsidiaries, and such petition or other
pleading shall not be dismissed or discharged within 15 Business Days of commencement. 
 8.7. Voluntary Bankruptcy. The Company or
any of its Subsidiaries shall: (i) commence a voluntary case seeking liquidation or reorganization under the United States Bankruptcy Code or any other or similar insolvency or similar laws of any jurisdiction, (ii) consent to the

(iii) make a general assignment for the benefit of its creditors, or (iv) fail generally to pay its debts as the debts become due. 
 9. Remedies. Upon and after the occurrence of an Event of Default, so long as the Majority Holders have consented in writing, the Holder shall, by written notice to the Company, be entitled to accelerate this Note and declare the
entire Principal 

  

 17 

 
Amount and all accrued and unpaid interest thereon immediately due and payable and exercise all other rights and remedies available to the Holder under the
Purchase Agreement and applicable law, all such rights and remedies being cumulative and enforceable alternatively, successively or concurrently. 
 10. Prepayment. Except as set out in Section 6, the Company may not prepay this Note prior to the Maturity Date without the prior written consent of the Majority Holders.

the parties. The Company shall not be permitted to assign this Note without the prior written consent of the Majority Holders. Notwithstanding the foregoing, in the event that the Company conducts a restructuring, capital reorganization,
recapitalization or reincorporation, the Company shall procure that any entity that acquires all or substantially all of the Company’s assets or the listing entity that owns, directly or indirectly, the shares and assets of the Group, shall

this Note, in which the Company shall record the name and address of the Holder and the name and address of each permitted transferee. The Holder shall notify the Company of any change of name or address and promptly after receiving such
notification the Company shall record such information in such register. 
 14.2. Transfer. Subject to applicable laws and
regulations, this Note and all rights hereunder may be transferred or assigned in whole or in part by the Holder by giving written notice to the Company prior thereto, together with a written opinion of Holder’s counsel, or other evidence
reasonably satisfactory to the Company, to the effect that such transfer or assignment may be effected without registration or qualification under applicable US securities laws then in effect, and the Company shall assist the Holder in consummating
any such transfer or assignment; provided, however, that this Note may not be transferred to any Person who, to the Knowledge of the transferring Holder, is a direct competitor and/or customer of the Company at the relevant time. Each
Note thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with 

  

 18 

 
applicable securities laws and regulations, unless in the written opinion of counsel for the Company such legend is not required in order to ensure
compliance with applicable laws and regulations. the Company may issue stop transfer instructions to its transfer agent in connection with such restrictions. A transfer of this Note may be effected only by a surrender hereof to the Company and the
issuance by the Company of a new Note or Notes in replacement thereof, which shall, subject to the restrictions set forth herein, be registered by the Company in accordance with Section 14.1 hereof once an executed copy of the replacement note
has been executed by the transferee. Prior to presentation of this Note for registration of transfer, the Company shall treat the registered holder hereof as the owner and holder of this Note for the purpose of receiving all payments of principal
and interest hereon and for all other purposes whatsoever, whether or not this Note shall be overdue and the Company shall not be affected by notice to the contrary.

 19. Notices. All notices, demands and other communications provided for or permitted hereunder shall be made in writing and shall be by registered or certified first-class mail, return receipt requested,
facsimile, courier service or personal delivery to the respective addresses of the parties as set forth on the signature pages hereto. All such notices, demands and other communications shall be deemed to have been duly given when delivered by hand,
if personally delivered; when delivered by courier, if delivered by commercial courier service; five Business Days after being deposited in the mail, postage prepaid, if mailed; and when receipt is mechanically acknowledged, if faxed. Any party may

 19 

 21. GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK, EXCLUDING THAT BODY OF LAW RELATING TO CONFLICT OF LAWS. 
 22. Dispute Resolution. 
 22.1. Dispute Resolution. Any disputes, claims or controversies among the parties arising out of or in connection with this Agreement, whether in
contract, tort, equity or otherwise and including those relating to the existence, meaning, interpretation, effect, validity, performance, termination or enforcement of this Agreement (all of which are referred to as “Disputes”)
shall be referred to and finally resolved through binding and final arbitration in accordance with the Rules of the London Court of International Arbitration (the “Arbitration Rules”) in effect, at the time of commencement of the
arbitration. The Arbitration Rules are hereby incorporated by reference into this clause except as modified herein. In such event, each party agrees to submit itself and its property to the jurisdiction of the arbitration tribunal convened to
resolve such Dispute. 
 22.2. Appointment of Arbitrators. The arbitration tribunal shall consist of three arbitrators. One
arbitrator shall be nominated by each of the two respective parties in the dispute and the third, who shall be the Chairman of the arbitration tribunal, shall be nominated by the two party nominated arbitrators within 14 calendar days of the last of
their appointments (failing which the Chairman shall be selected by the London Court of International Arbitration). It is hereby expressly agreed that if there is more than one claimant party and/or more than one respondent party, the claimant
parties shall together nominate one arbitrator and the respondent parties shall together nominate one arbitrator. 
 22.3. Authority of
the Arbitrators. The arbitrators shall have the authority to assess the costs and expenses of the arbitration proceedings (including, but not limited to, the parties’ reasonable legal costs and expenses) and allocate them between the
parties in whatever manner or allocation the arbitrators deem appropriate. 
 22.4. Conduct of the Arbitration. The arbitration
proceedings shall be conducted, and the award or decision (the “Award”) of the arbitrators shall be rendered, in the English language. 
 22.5. Place of Arbitration. The seat, or legal place, of the arbitration shall be London, England. 
 22.6. Joinder of Disputes. In order to facilitate the comprehensive resolution of related Disputes, all claims among the parties that arise under or in connection with this Agreement may be dealt with in a single set of arbitration
proceedings. Upon the request of any party to any arbitration proceedings commenced pursuant to this Section 22, the arbitral tribunal shall consolidate those arbitration proceedings with any other proceedings involving any of the parties
hereto, and relating to this Agreement, if the arbitral tribunal determines that: 
 (a) there are issues of fact or law
common to the proceedings so that a consolidated proceeding would be more efficient than separate proceedings; and 
  

 20 

 (b) no party would be materially prejudiced as a result of such consolidation through undue delay or
otherwise. 
 In the event of different determinations of (i) and (ii) by different arbitral tribunals constituted under this
Agreement, the ruling of the arbitral tribunal constituted first in time shall be determinative, and unless the parties otherwise agree, such arbitral tribunal shall serve as the arbitral tribunal for any consolidated arbitration proceedings.

 22.7. Provisional Remedies. By agreeing to arbitration, the parties to this Agreement do not intend to deprive any court of its
jurisdiction to issue a pre-arbitral injunction, pre-arbitral attachment or other order in aid of arbitration proceedings and the enforcement of any Award. Without prejudice to such national court, the arbitral tribunal established under this
Section 22 shall have full authority to grant provisional remedies. 
 22.8. Decision Final. 
 (a) The Award shall be final and binding upon the parties as from the date rendered. Judgment upon any Award may be entered in any court having
jurisdiction thereof. 
 (b) The parties waive any rights of application or appeal to any court or tribunal of competent jurisdiction to the
fullest extent permitted by law in connection with any question of law arising in the course of arbitration or with respect to any Award made except for actions relating to enforcement of this Agreement or arbitral Award and except for actions
seeking interim or other provisional relief in aid of arbitration proceeding in any court of competent jurisdiction. 
 22.9. Payment of
the Award. Any monetary award shall be made and payable in US$ free of any tax, deduction or set off. Each party against which the Award assesses a monetary obligation shall pay that obligation on or before the 30th day following the date of the
Award or such other date as the Award may provide. The arbitral tribunal shall have the authority to award any remedy or relief proposed by the claimant(s) or respondent(s) in accordance with the terms of this Agreement, including, a declaratory
judgment, specific performance of any obligation created under this Agreement or the issuance of any injunction. 
 22.10.
Confidentiality of Arbitration. Once any Dispute has been submitted to arbitration proceedings pursuant to this Section 22, such Dispute shall be resolved in a confidential manner. Unless required by applicable law, neither party shall

  

 21 

 
disclose or permit the disclosure to any person except its counsel, consultants and controlled Affiliates of any information about the evidence adduced or
the documents produced by the other party in the arbitration proceedings or about the existence, contents or results of the proceeding except as may be required by a Governmental Authority or as required in an action in aid of arbitration or for
enforcement of an arbitral award. Before making any disclosure permitted by the preceding sentence, the party intending to make such disclosure shall give the other party reasonable written notice of the intended disclosure and afford the other
party a reasonable opportunity to protect its interests. 
 23. Amendments and Waivers. No amendments or waivers of any provision of
this Note, and no consent by the Holder to any departure by the Company, shall in any event be effective unless the same shall be in writing, and signed by the Company and the Majority Holders, and all Notes shall be similarly amended and such
waiver or consent shall be effective only in the specific instance and for the purpose for which given. 
 24. Severability. Any
provision of this Note that is prohibited or unenforceable in a jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 25. WAIVER OF JURY TRIAL. THE COMPANY AND THE HOLDER HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS NOTE OR THE TRANSACTIONS CONTEMPLATED BY THIS NOTE. THE COMPANY AND THE HOLDER HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS NOTE AND THE TRANSACTIONS CONTEMPLATED BY THIS NOTE, AS APPLICABLE, BY, AMONG OTHER THINGS,
THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 25.  
 26. Heading; References. All headings used herein are used for

	  	n/aSecond Amendment to Office and Industrial Lease Agreement

 EXHIBIT 4.14 
 SECOND AMENDMENT TO OFFICE AND INDUSTRIAL LEASE AGREEMENT 
 THIS AMENDMENT is entered into on
December 30, 2008, by and between LIBERTY PROPERTY PHILADELPHIA LIMITED PARTNERSHIP V, a Pennsylvania limited partnership (“Landlord”) and WUXI APPTEC INC., a corporation organized under the laws of Delaware
(“Tenant”), successor to APPTEC LABORATORY SERVICES, LLC, a limited liability company organized under the laws of Minnesota (“Assignor”) 
 WHEREAS, Landlord, and Tenant are parties to that certain Office and Industrial Lease Agreement dated December 3, 2002, as amended by First
Amendment dated December 30, 2005 (collectively, the “Lease”), with respect to Premises located at 4751 League Island Boulevard, Philadelphia, Pennsylvania; and 
 WHEREAS, Landlord and Tenant desire to further amend the Lease as set forth below. 
 NOW, THEREFORE, in consideration of the mutual promises contained herein and for other good and valuable consideration, and intending to be
legally bound, Landlord and Tenant agree as follows: 
 1. All capitalized terms used in this Amendment and not otherwise defined herein
shall have the meanings given to them in the Lease. 
 2. Tenant and Assignor confirm that Assignor has assigned the Lease to Tenant and that
Tenant has assumed all the obligations of Assignor under the Lease. Landlord confirms that Landlord has consented to the aforesaid assignment and assumption of the Lease. 
 3. A new paragraph is added at the end of Section 27 of the Lease, to read as follows: 
 “In lieu
of maintaining an LC as required above, Tenant may at any time during the Term of this Lease, deposit with Landlord a cash sum equal to the required Security Deposit in the amount set forth above, which sum shall be retained by Landlord, without
interest and not in trust or in a separate account, as security for the payment by Tenant of the Rent and all other charges or payments to be paid hereunder and the performance of the covenants and obligations contained herein. If at any time Tenant
shall be in default under any of the provisions of this Lease, Landlord shall be entitled, at its sole discretion, to apply the Security Deposit to payment of (i) any Rent or other charge for the payment of which Tenant shall be in default,
(ii) any expense incurred by Landlord in curing any default of Tenant, and/or (iii) any other sums due to Landlord in connection with any default or the curing thereof, including, without limitation, any damages incurred by Landlord by reason
of such default. If any portion of the Security Deposit is used, applied or retained by Landlord for any purpose set forth above, Tenant shall, within 10 days after demand therefor is made by Landlord, deposit cash with Landlord in an amount
sufficient to restore the Security Deposit to its original amount. Any portion of such Security Deposit which shall not be utilized for any such purpose shall be returned to Tenant following the expiration of this Lease and proper surrender of the
Premises to Landlord. The Security Deposit shall not 

 
be mortgaged, assigned or encumbered in any manner whatsoever by Tenant. At Tenant’s election from time to time Tenant may replace the cash Security
Deposit with an LC that satisfies the criteria set forth above, whereupon Landlord shall repay to Tenant the un-applied portion of the cash Security Deposit.” 
 4. 
 (a) Except as expressly modified by this Amendment, the terms of the Lease shall remain unmodified. As
modified hereby, the Lease shall continue in full force and effect. 
 (b) This Amendment shall be governed and construed according to the
laws of the Commonwealth of Pennsylvania. 
 (c) This Amendment may be executed by facsimile. This Amendment may be executed in counterparts,
all of which together shall be deemed to be one original document.

 IN WITNESS WHEREOF, Landlord and Tenant have executed this Amendment on the date set forth above.
