payment of the Triggering Event Payment, any Note accepted for payment pursuant to the Triggering Event Offer will cease to accrue interest on and after the Triggering Event Payment Date; 

  
 9 

 (v) that Holders electing to have any Notes purchased pursuant to a
Triggering Event Offer will be required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in
the notice prior to the close of business on the third Business Day preceding the Triggering Event Payment Date;

Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes; provided that the Paying Agent receives at the address specified in the notice, not later than the close of business
on the 30th day following the date of the Triggering Event notice, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder
is withdrawing its tendered Notes and its election to have such Notes purchased;

thereof); and 
 (viii) the other instructions, as determined by the Company consistent with this Section 2.05, that a

the Holder receives such notice. If (A) the notice is sent in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice
or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect. 

(b) On the Triggering Event Payment Date, the Company will, to the extent lawful: 

(i) accept for payment all Notes or portions of Notes (of US$200,000 or integral multiples of US$1,000 in excess thereof)
properly tendered pursuant to the Triggering Event Offer;

the Triggering Event Payment Date, an amount equal to the Triggering Event Payment in respect of all Notes or portions of Notes properly tendered; and

properly tendered, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each such Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided
that each new Note will be in a principal amount of US$200,000 or a multiple of US$1,000 in excess thereof. 

  
 10 

 (d) If the Triggering Event Payment Date is on or after the relevant Record Date and on or
before the related Interest Payment Date, any accrued and unpaid interest to the Triggering Event Payment Date shall be paid on such Interest Payment Date to the Person in whose name a Note is registered at the close of business on such Record Date.

 (e) The Company will not be required to make a Triggering Event Offer upon a Triggering Event if a third party makes such an offer in the
manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or
defaults its offer, the Company will be required to make a Triggering Event Offer treating the date of such termination or default as though it were the date of the Triggering Event. 

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, to the extent
applicable, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Triggering Event. To the extent that the provision of any
such securities laws or regulations conflicts with the Triggering Event Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Triggering
Event Offer provisions of the Notes by virtue of any such conflict.

calendar days (or such shorter period acceptable to the Trustee) prior to the date the notice of redemption is to be mailed, notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed, and the Notes to be
redeemed will be selected (i) if listed on a national securities exchange or held through the clearing systems then in compliance with the requirements of such national securities exchange or the clearing system, and (ii) if the Notes are
not listed on any securities exchange and are not held through the clearing systems then pro rata, by lot or in such other manner as the trustee deems appropriate in its sole discretion, unless otherwise required by law and which may provide for the
selection for redemption of a portion of the principal amount of any Security of such series; provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the
minimum authorized denomination) for such Security. In any case where more than one Security of such series is registered in the same name, the Trustee may treat the aggregate principal amount so registered as if it were represented by one Security
of such series. If the Notes are in definitive form, the Trustee shall, as soon as practicable, notify the Company in writing of the Securities and portions of Securities so selected.”

 “All payments of principal, premium, if any, and interest made by the Company in
respect of any Security shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (collectively, “Taxes”) imposed or levied by
or within the British Virgin Islands, the Cayman Islands, the PRC or any jurisdiction where the Company is otherwise considered by a taxing authority to be a resident for tax purposes (in each case, including any political subdivision or any
authority therein or thereof having power to tax) (the “Relevant Jurisdiction”), unless such withholding or deduction of such Taxes is required by law. If the Company is required to make such withholding or deduction, the Company
shall pay such additional amounts (“Additional Amounts”) as will result in receipt by each Holder of Securities of such amounts as would have been received by such Holder had no such withholding or deduction of such Taxes been
required, except that no such Additional Amounts shall be payable: 
 (i) in respect of any such Taxes that would not have
been imposed, deducted or withheld but for the existence of any connection (whether present or former) between the Holder or beneficial owner of a Security and the Relevant Jurisdiction other than merely holding such Security or receiving principal,
premium, if any, or interest in respect thereof (including such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Jurisdiction or treated as a resident thereof or being or having been physically
present or engaged in a trade or business therein or having or having had a permanent establishment therein); 
 (ii) in
respect of any Security presented for payment (where presentation is required) more than 30 days after the relevant date, except to the extent that the Holder thereof would have been entitled to such Additional Amounts on presenting the same for
payment on the last day of such 30-day period. For this purpose, the “relevant date” in relation to any Security means the later of (a) the due date for such payment or (b) the date
such payment was made or duly provided for; 
 (iii) in respect of any Taxes that would not have been imposed, deducted or
withheld but for a failure of the Holder or beneficial owner of a Security to comply with a timely request by the Company addressed to the Holder or beneficial owner to provide information concerning such Holder’s or beneficial owner’s
nationality, residence, identity or connection with any Relevant Jurisdiction, if and to the extent that due and timely compliance with such request is required under the tax laws of such jurisdiction in order to reduce or eliminate any withholding
or deduction as to which Additional Amounts would have otherwise been payable to such Holder; 
 (iv) in respect of any Taxes
imposed as a result of a Security being presented for payment (where presentation is required) in the Relevant Jurisdiction, unless such Security could not have been presented for payment elsewhere; 

(v) in respect of any estate, inheritance, gift, sales, transfer, personal property or similar Taxes; 

  
 13 

 (vi) to any Holder of a Security that is a fiduciary, partnership or person
other than the sole beneficial owner of any payment to the extent that such payment would be required to be included in the income under the laws of a Relevant Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the
fiduciary, or a member of that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner or beneficial owner been the Holder thereof; 

(vii) with respect to any withholding or deduction that is imposed in connection with Sections 1471-1474 of the U.S. Internal
Revenue Code and U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement between the United States and any other jurisdiction implementing or relating to FATCA or any
non-U.S. law, regulation or guidance enacted or issued with respect thereto; 

(viii) any such Taxes payable otherwise than by deduction or withholding from payments under or with respect to any Security;
or 
 (ix) any combination of Taxes referred to in the preceding clauses (i) through (viii) above.” 

(c) Section 14.01(h) of the Base Indenture shall be replaced in its entirety by the following with respect to the Notes only: 

“to conform the text of this Indenture or any series of the Securities to any provision of the section entitled “Description of Debt
Securities” in the Prospectus or of the section entitled “Description of the Notes” in the Prospectus Supplement to the extent that such provision in the Prospectus or the Prospectus Supplement, as the case may be, was intended to be
a verbatim recitation of a provision of this Indenture or such series of the Securities as evidenced by an Officers’ Certificate;” 

(d) Clause (xi) of Section 14.02(a) of the Base Indenture shall be replaced in its entirety by the following with respect to the
Notes only: 
 “reduce the amount of the premium payable upon the redemption or repurchase of any Security or change the time at which
any Security may be redeemed or repurchased as described in Section 4.07 of the Base Indenture or as described in Section 2.03 or 2.05 of the Sixth Supplemental Indenture, whether through an amendment or waiver of provisions in the
covenants, definitions or otherwise (except through amendments to the definition of “Triggering Event” if applicable).”

 (ii)    the purchase date (which shall
be no earlier than 30 days and no later than 60 days from the date such notice is mailed) (the “Triggering Event Payment Date”); 

(iii)    that Notes must be tendered in amounts of US$200,000 or multiples of US$1,000 in excess thereof,
and any Note not properly tendered will remain outstanding and continue to accrue interest; 

(iv)    that, unless the Company defaults in the payment of the Triggering Event Payment, any Note accepted
for payment pursuant to the Triggering Event Offer will cease to accrue interest on and after the Triggering Event Payment Date; 

(v)    that Holders electing to have any Notes purchased pursuant to a Triggering Event Offer will be
required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of
business on the third Business Day preceding the Triggering Event Payment Date; 
 (vi)    that Holders
shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes; provided that the Paying Agent receives at the address specified in the notice, not later than the close of business on the
30th day following the date of the Triggering Event notice, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is
withdrawing its tendered Notes and its election to have such Notes purchased; 
 (vii)    that if a
Holder is tendering less than all of its Notes, such Holder will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to US$200,000 or an integral
multiple of US$1,000 in excess thereof); and 
 (viii)    the other instructions, as determined by the
Company consistent with this Section 2.05, that a Holder must follow. 
 The notice, if sent in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives such notice. If (A) the notice is sent in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is
defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect. 

  
 10 

 (b)    On the Triggering Event Payment Date, the Company will, to the
extent lawful: 
 (i)    accept for payment all Notes or portions of Notes (of US$200,000 or integral
multiples of US$1,000 in excess thereof) properly tendered pursuant to the Triggering Event Offer; 

(ii)    deposit with the Paying Agent, one Business Day prior to the Triggering Event Payment Date, an
amount equal to the Triggering Event Payment in respect of all Notes or portions of Notes properly tendered; and 

(iii)    deliver or cause to be delivered to the Trustee for cancellation the Notes properly accepted
together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company in accordance with the terms of this Section 2.05. 

(c)    The Paying Agent shall promptly mail, to each Holder who properly tendered Notes, the purchase price for such Notes
properly tendered, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each such Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided
that each new Note will be in a principal amount of US$200,000 or a multiple of US$1,000 in excess thereof. 
 (d)    If
the Triggering Event Payment Date is on or after the relevant Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest to the Triggering Event Payment Date shall be paid on such Interest Payment Date to the
Person in whose name a Note is registered at the close of business on such Record Date. 
 (e)    The Company will not
be required to make a Triggering Event Offer upon a Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases
all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, the Company will be required to make a Triggering Event Offer treating the date of such termination or default as
though it were the date of the Triggering Event. 
 (f)    The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act, to the extent applicable, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes
as a result of a Triggering Event. To the extent that the provision of any such securities laws or regulations conflicts with the Triggering Event Offer provisions of the Notes, the Company will comply with those securities laws and regulations and
will not be deemed to have breached its obligations under the Triggering Event Offer provisions of the Notes by virtue of any such conflict.

Indenture of the option applicable to Section 12.03(c) thereof, the Company shall, subject to the satisfaction of the conditions set forth in Section 12.03(d) thereof, be released from its obligations under the covenants contained in
Section 6.04 and Section 6.06 thereof and from its obligations under the covenants contained in Section 2.04 and Section 2.05 of this Seventh Supplemental Indenture, on and after the date the conditions set forth in

 Section 2.08    Supplemental Indentures. 

(a)    Definition of “Principal Controlled Entity” under Section 1.01 of the Base Indenture shall be
replaced in its entirety by the following with respect to the Notes only: 
 ““Principal Controlled Entities” at any
time shall mean one of the Non-listed Controlled Entities of the Company: 
 (i) as
to which one or more of the following conditions is/are satisfied: 
 (A) its total revenue or (in the case of one of the Non-listed Controlled Entities of the Company which has one or more Non-listed Controlled Entities) consolidated total revenue attributable to the Company is at least 10% of
the consolidated total revenue of the Company; 
 (B) its net profit or (in the case of one of the Non-listed Controlled Entities of the Company which has one or more Non-listed Controlled Entities) consolidated net profit attributable to the Company (in each case before
taxation and exceptional items) is at least 10% of the consolidated net profit of the Company (before taxation and exceptional items); or 

(C) its net assets or (in the case of one of the Non-listed Controlled Entities of the
Company which has one or more Non-listed Controlled Entities) consolidated net assets attributable to the Company (in each case after deducting minority interests in Subsidiaries) are at least 10% of the
consolidated net assets of the Company (after deducting minority interests in Subsidiaries); 

  
 12 

 all as calculated by reference to the then latest audited financial
statements (consolidated or, as the case may be, unconsolidated) of the Non-listed Controlled Entity of the Company and the then latest audited consolidated financial statements of the
Company; provided that, in relation to clauses (A), (B) and (C) above: 
 (1) in the case of a
corporation or other business entity becoming a Non-listed Controlled Entity after the end of the financial period to which the latest consolidated audited accounts of the Company relate, the reference to the
then latest consolidated audited accounts of the Company and its Non-listed Controlled Entities for the purposes of the calculation above shall, until the consolidated audited accounts of the Company for the
financial period in which the relevant corporation or other business entity becomes a Non-listed Controlled Entity are issued, be deemed to be a reference to the then latest consolidated audited accounts of
the Company and its Non-listed Controlled Entities adjusted to consolidate the latest audited accounts (consolidated in the case of a Non-listed Controlled Entity which
itself has Controlled Entities) of such Non-listed Controlled Entity in such accounts; 

(2) if at any relevant time in relation to the Company or any Non-listed Controlled
Entity which itself has Non-listed Controlled Entities, no consolidated accounts are prepared and audited, total revenue, net profit or net assets of the Company and/or any such
Non-listed Controlled Entity shall be determined on the basis of pro forma consolidated accounts prepared for this purpose by or on behalf of the Company; 

(3) if at any relevant time in relation to any Non-listed Controlled Entity, no
accounts are audited, its net assets (consolidated, if appropriate) shall be determined on the basis of pro forma accounts (consolidated, if appropriate) of the relevant Non-listed Controlled Entity prepared
for this purpose by or on behalf of the Company; and 
 (4) if the accounts of any
Non-listed Controlled Entity (not being a Non-listed Controlled Entity referred to in proviso (1) above) are not consolidated with the accounts of the Company, then
the determination of whether or not such Non-listed Controlled Entity is a Principal Controlled Entity shall be based on a pro forma consolidation of its accounts (consolidated, if appropriate) with the
consolidated accounts of the Company (determined on the basis of the foregoing); or 
 (ii) to which is transferred all or
substantially all of the assets of a Controlled Entity which immediately prior to the transfer was a Principal Controlled Entity; provided that, with effect from such transfer, the Controlled Entity which so transfers its assets and
undertakings shall cease to be a Principal Controlled Entity (but without prejudice to paragraph (i) above) and the Controlled Entity to which the assets are so transferred shall become a Principal Controlled Entity. 

An Officers’ Certificate delivered to the Trustee certifying in good faith as to whether or not a
Non-listed Controlled Entity is a Principal Controlled Entity shall be conclusive in the absence of manifest error.” 

  
 13 

 (b)    Section 4.02(a) of the Base Indenture shall be replaced in its
entirety by the following with respect to the Notes only: 
 “If the Company shall at any time elect to redeem all or any portion of the
Securities of a series then Outstanding, it shall at least 15 calendar days (or such shorter period acceptable to the Trustee) prior to the date the notice of redemption is to be mailed, notify the Trustee of such Redemption Date and of the
principal amount of Securities to be redeemed, and the Notes to be redeemed will be selected (i) if listed on a national securities exchange or held through the clearing systems then in compliance with the requirements of such national
securities exchange or the clearing system, and (ii) if the Notes are not listed on any securities exchange and are not held through the clearing systems then pro rata, by lot or in such other manner as the trustee deems appropriate in its sole
discretion, unless otherwise required by law and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series; provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. In any case where more than one Security of such series is registered in the same name, the Trustee may treat the aggregate
principal amount so registered as if it were represented by one Security of such series. If the Notes are in definitive form, the Trustee shall, as soon as practicable, notify the Company in writing of the Securities and portions of Securities so
selected.” 
 (c)    Section 6.05(a) of the Base Indenture shall be replaced in its entirety by the following with
respect to the Notes only: 
 “All payments of principal, premium, if any, and interest made by the Company in respect of any Security
shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (collectively, “Taxes”) imposed or levied by or within the British
Virgin Islands, the Cayman Islands, the PRC or any jurisdiction where the Company is otherwise considered by a taxing authority to be a resident for tax purposes (in each case, including any political subdivision or any authority therein or thereof
having power to tax) (the “Relevant Jurisdiction”), unless such withholding or deduction of such Taxes is required by law. If the Company is required to make such withholding or deduction, the Company shall pay such additional
amounts (“Additional Amounts”) as will result in receipt by each Holder of Securities of such amounts as would have been received by such Holder had no such withholding or deduction of such Taxes been required, except that no such
Additional Amounts shall be payable: 
 (i)    in respect of any such Taxes that would not have been
imposed, deducted or withheld but for the existence of any connection (whether present or former) between the Holder or beneficial owner of a Security and the Relevant Jurisdiction other than merely holding such Security or receiving principal,
premium, if any, or interest in respect thereof (including such Holder or beneficial owner being or having been a national, domiciliary or resident of such Relevant Jurisdiction or treated as a resident thereof or being or having been physically
present or engaged in a trade or business therein or having or having had a permanent establishment therein); 

  
 14 

 (ii)    in respect of any Security presented for payment
(where presentation is required) more than 30 days after the relevant date, except to the extent that the Holder thereof would have been entitled to such Additional Amounts on presenting the same for payment on the last day of such 30-day period. For this purpose, the “relevant date” in relation to any Security means the later of (a) the due date for such payment or (b) the date such payment was made or duly provided
for; 
 (iii)    in respect of any Taxes that would not have been imposed, deducted or withheld but for a
failure of the Holder or beneficial owner of a Security to comply with a timely request by the Company addressed to the Holder or beneficial owner to provide information concerning such Holder’s or beneficial owner’s nationality,
residence, identity or connection with any Relevant Jurisdiction, if and to the extent that due and timely compliance with such request is required under the tax laws of such jurisdiction in order to reduce or eliminate any withholding or deduction
as to which Additional Amounts would have otherwise been payable to such Holder; 
 (iv)    in respect of
any Taxes imposed as a result of a Security being presented for payment (where presentation is required) in the Relevant Jurisdiction, unless such Security could not have been presented for payment elsewhere; 

(v)    in respect of any estate, inheritance, gift, sales, transfer, personal property or similar Taxes;

 (vi)    to any Holder of a Security that is a fiduciary, partnership or person other than the sole
beneficial owner of any payment to the extent that such payment would be required to be included in the income under the laws of a Relevant Jurisdiction, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, or a member of
that partnership or a beneficial owner who would not have been entitled to such Additional Amounts had that beneficiary, settlor, partner or beneficial owner been the Holder thereof; 

(vii)    with respect to any withholding or deduction that is imposed in connection with Sections 1471-1474
of the U.S. Internal Revenue Code and U.S. Treasury regulations thereunder (“FATCA”), any intergovernmental agreement between the United States and any other jurisdiction implementing or relating to FATCA or any non-U.S. law, regulation or guidance enacted or issued with respect thereto; 

(viii)    any such Taxes payable otherwise than by deduction or withholding from payments under or with
respect to any Security; or 
 (ix)    any combination of Taxes referred to in the preceding clauses
(i) through (viii) above.” 

  
 15 

 (d)    Section 7.01(e) of the Base Indenture shall be replaced in its
entirety by the following with respect to the Notes only: 
 “(i) there occurs with respect to any indebtedness of the Company, whether
such indebtedness exists as of the date hereof or shall hereafter be created, (A) an event of default that has resulted in the holder thereof declaring the principal of such indebtedness to be due and payable prior to its stated maturity or
(B) a failure to make a payment of principal, interest or premium when due (after giving effect to the expiration of any applicable grace period therefor, a “Payment Default”) and (ii) the outstanding principal amount of such
indebtedness, together with the outstanding principal amount of any of the Company’s other indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, is equal to or exceeds the greater of
(x) US$100,000,000 (or the Dollar Equivalent thereof) and (y) 2.5% of the Total Equity of the Company;” 

(e)    Section 7.01(f) of the Base Indenture shall be replaced in its entirety by the following with respect to the Notes
only: 
 “one or more final judgments or orders for the payment of money are rendered against the Company and are not paid or
discharged, and there is a period of 90 consecutive days following entry of the final judgment or order that causes the aggregate amount for all such final judgments or orders outstanding and not paid or discharged against the Company (net of any
amounts that the Company’s insurance carriers have paid or agreed to pay with respect thereto under applicable policies) to exceed the greater of (x) US$100,000,000 (or the Dollar Equivalent thereof) and (y) 2.5% of the Total Equity of the
Company, during which a stay of enforcement, by reason of a pending appeal or otherwise, is not in effect;” 

(f)    First sentence of Section 7.02(b) of the Base Indenture shall be replaced in its entirety by the following
with respect to the Notes only: 
 “In the event of a declaration of acceleration with respect to the Securities of any series because
of an Event of Default specified in Section 7.01(e) above shall occur, the declaration of acceleration with respect to the Securities of such series shall be automatically annulled if the Default triggering such Event of Default pursuant to
Section 7.01(e) above shall be remedied or cured by the Company or waived by the holders of the relevant indebtedness within 30 days after the declaration of acceleration with respect thereto and:” 

(g)    Section 14.01(h) of the Base Indenture shall be replaced in its entirety by the following with respect to the Notes
only: 
 “to conform the text of this Indenture or any series of the Securities to any provision of the section entitled
“Description of Debt Securities” in the Prospectus or of the section entitled “Description of the Notes” in the Prospectus Supplement to the extent that such provision in the Prospectus or the Prospectus Supplement, as the case
may be, was intended to be a verbatim recitation of a provision of this Indenture or such series of the Securities as evidenced by an Officers’ Certificate;” 

  
 16 

 (h)    Clause (xi) of Section 14.02(a) of the Base Indenture
shall be replaced in its entirety by the following with respect to the Notes only: 
 “reduce the amount of the premium payable upon
the redemption or repurchase of any Security or change the time at which any Security may be redeemed or repurchased as described in Section 4.07 of the Base Indenture or as described in Section 2.03 or 2.05 of the Seventh Supplemental
Indenture, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise (except through amendments to the definition of “Triggering Event” if applicable).”

 4.375% Note Due 2024

 This Note is one of a duly authorized issue of debt securities of the Company of the series designated as the “4.375% Notes due
2024” (the “Notes”), all issued or to be issued under and pursuant to an Indenture, dated as of November 28, 2012 (the “Base Indenture”), duly executed and delivered by and between the Company and The Bank
of New York Mellon, as trustee (the “Trustee,” which term includes any successor trustee), as supplemented by the Seventh Supplemental Indenture, dated as of November 14, 2018 (the “Seventh Supplemental Indenture”),
duly executed and delivered by and between the Company and the Trustee. The Base Indenture as supplemented and amended by the Seventh Supplemental Indenture and all indentures supplemental thereto with respect to the Notes is referred to herein as
the “Indenture”. Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Indenture. 

1. Interest. The Company promises to pay interest on the principal amount of this Note at a rate of 4.375% per annum. The Company will
pay interest semi-annually in arrears on May 14 and November 14 of each year. If a payment date is not a Business Day as defined in the Indenture at a Place of Payment, payment may be made at that place on the next succeeding day that is a
Business Day, and no interest shall accrue for the intervening period. Interest shall be computed on the basis of a 360-day year of twelve 30-day months and, in the case
of an incomplete month, the actual number of days elapsed. 
 2. Method of Payment. The Company shall pay interest on the Notes
(except Defaulted Interest), if any, to the Persons in whose name such Notes are registered at the close of business on the Record Date referred to on the face of this Note immediately preceding the related Interest Payment Date, even if any Notes
are canceled, repurchased or redeemed on or after such Record Date and on or before such Interest Payment Date. Payment of interest on the Notes shall be made, in the currency of the United States of America that at the time is legal tender for
payment of public and private debts, at the specified office of the Paying Agent or, at the option of the Company, by check mailed to the address of the Person entitled thereto as such address shall appear in the Register or, in accordance with
arrangements satisfactory to the Trustee, by wire transfer to an account designated by the Holder. 
 3. Paying Agent, Authenticating
Agent and Registrar. Initially, The Bank of New York Mellon, the Trustee, will act as Paying Agent, Authenticating Agent and Registrar. The Company may change or appoint any Paying Agent or Registrar without notice to any Noteholder. The Company
may act in any such capacity. 
 4. Indenture. The terms of the Notes include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (“TIA”) as in effect on the date the Indenture is qualified. The Notes are subject to all such terms, and Noteholders are referred to the Indenture and TIA for a
statement of such terms. The Notes are unsecured general obligations of the Company and constitute the series designated on the face of this Note as the “4.375% Notes due 2024,” initially limited to US$600,000,000 in aggregate principal
amount. The Company will furnish to any Noteholder upon written request and without charge a copy of the Base Indenture and the Seventh Supplemental Indenture. Requests may be made to: Baidu, Inc., Baidu Campus, No. 10 Shangdi 10th Street,

integral multiple of US$1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Notes may be presented for exchange or for registration of transfer (duly endorsed or with the form
of transfer endorsed thereon duly executed if so required by the Company or the Registrar) at the office of the Registrar or at the office of any transfer agent designated by the Company for such purpose. The Company need not exchange or register
the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. 

7. Persons Deemed Owners. The registered Noteholder may be treated as its owner for all purposes. 

8. Amendments, Supplements and Waivers. The Indenture and the Notes may be amended or supplemented as provided in the Indenture. Any
consent or waiver by the Noteholders as provided in the Indenture shall be conclusive and binding upon such Holders and upon all future Noteholders and holders of any security issued upon the registration of transfer hereof or in exchange herefor or

 REVERSE OF NOTE 

BAIDU, INC. 
 4.875% Note Due 2028

 This Note is one of a duly authorized issue of debt securities of the Company of the series designated as the “4.875% Notes due
2028” (the “Notes”), all issued or to be issued under and pursuant to an Indenture, dated as of November 28, 2012 (the “Base Indenture”), duly executed and delivered by and between the Company and The Bank
of New York Mellon, as trustee (the “Trustee,” which term includes any successor trustee), as supplemented by the Seventh Supplemental Indenture, dated as of November 14, 2018 (the “Seventh Supplemental Indenture”),
duly executed and delivered by and between the Company and the Trustee. The Base Indenture as supplemented and amended by the Seventh Supplemental Indenture and all indentures supplemental thereto with respect to the Notes is referred to herein as
the “Indenture”. Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Indenture. 

1. Interest. The Company promises to pay interest on the principal amount of this Note at a rate of 4.875% per annum. The Company will
pay interest semi-annually in arrears on May 14 and November 14 of each year. If a payment date is not a Business Day as defined in the Indenture at a Place of Payment, payment may be made at that place on the next succeeding day that is a
Business Day, and no interest shall accrue for the intervening period. Interest shall be computed on the basis of a 360-day year of twelve 30-day months and, in the case
of an incomplete month, the actual number of days elapsed. 
 2. Method of Payment. The Company shall pay interest on the Notes
(except Defaulted Interest), if any, to the Persons in whose name such Notes are registered at the close of business on the Record Date referred to on the face of this Note immediately preceding the related Interest Payment Date, even if any Notes
are canceled, repurchased or redeemed on or after such Record Date and on or before such Interest Payment Date. Payment of interest on the Notes shall be made, in the currency of the United States of America that at the time is legal tender for
payment of public and private debts, at the specified office of the Paying Agent or, at the option of the Company, by check mailed to the address of the Person entitled thereto as such address shall appear in the Register or, in accordance with
arrangements satisfactory to the Trustee, by wire transfer to an account designated by the Holder. 
 3. Paying Agent, Authenticating
Agent and Registrar. Initially, The Bank of New York Mellon, the Trustee, will act as Paying Agent, Authenticating Agent and Registrar. The Company may change or appoint any Paying Agent or Registrar without notice to any Noteholder. The Company
may act in any such capacity. 
 4. Indenture. The terms of the Notes include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (“TIA”) as in effect on the date the Indenture is qualified. The Notes are subject to all such terms, and Noteholders are referred to the Indenture and TIA for a
statement of such terms. The Notes are unsecured general obligations of the Company and constitute the series designated on the face of this Note as the “4.875% Notes due 2028,” initially limited to US$400,000,000 in aggregate principal
amount. The Company will furnish to any Noteholder upon written request and without charge a copy of the Base Indenture and the Seventh Supplemental Indenture. Requests may be made to: Baidu, Inc., Baidu Campus, No. 10 Shangdi 10th Street,

 5. Redemption and Repurchase. The Notes are subject to optional redemption, and may
be the subject of a Triggering Event Offer, as further described in the Indenture. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. 

6. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in the denominations of US$200,000 or any
integral multiple of US$1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Notes may be presented for exchange or for registration of transfer (duly endorsed or with the form
of transfer endorsed thereon duly executed if so required by the Company or the Registrar) at the office of the Registrar or at the office of any transfer agent designated by the Company for such purpose. The Company need not exchange or register
the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. 

7. Persons Deemed Owners. The registered Noteholder may be treated as its owner for all purposes. 

8. Amendments, Supplements and Waivers. The Indenture and the Notes may be amended or supplemented as provided in the Indenture. Any
consent or waiver by the Noteholders as provided in the Indenture shall be conclusive and binding upon such Holders and upon all future Noteholders and holders of any security issued upon the registration of transfer hereof or in exchange herefor or
in lieu hereof, whether or not notation of such consent or waiver is made upon the Notes. 
 9. Defaults and Remedies. The Events of
Default relating to the Notes are defined in Section 7.01 of the Indenture. Upon the occurrence of an Event of Default, the rights and obligations of the Company, the Trustee and the Noteholders shall be as set forth in the applicable
provisions of the Indenture. 
 10. No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement
contained in the Indenture or the Notes, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or
of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability
being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.
