Schedule 1

Part A

Form of Global Certificate

CMU Instrument No.: CILHFB13003

21Vianet Group, Inc.

(incorporated in the Cayman Islands with limited
liability)

CNY1,000,000,000 7.875% Bonds due 2016

GLOBAL CERTIFICATE

This
Global Certificate is issued in respect of the CNY100,000,000 7.875% Bonds due 2016 (the Bonds) of 21Vianet Group, Inc. (the Issuer). The Issuer has entered into a Fiscal Agency Agreement (the Fiscal
Agency Agreement) dated March 20, 2013 with Citicorp International Limited as Fiscal Agent, Transfer Agent, CMU Lodging and Paying Agent, the Registrar, and any other agent or agents appointed from time to time in relation to the
Bonds. The holders of the Bonds are deemed to have notice of the provisions of the Fiscal Agency Agreement applicable to them.

Any reference
to the Conditions is to the terms and conditions of the Bonds set out in Part B of Schedule 1 of the Fiscal Agency Agreement and any reference herein to a particular numbered Condition shall be construed accordingly.

Unless otherwise defined herein or the context otherwise requires, words and expressions defined in the Conditions shall bear the same meaning when used
in this Global Certificate.

This is to certify that the Hong Kong Monetary Authority (the HKMA) is, at the date hereof,
entered in the register of Bondholders as the holder of Bonds in the principal amount of: CNY1,000,000,000 (Renminbi One Billion) or such other amount as is shown on the register of Bondholders as being represented by this Global Certificate and is
duly endorsed (for information purposes only) in the third column of Schedule A to this Global Certificate. For value received, the Issuer promises to pay to the person who appears at the relevant time on the register of Bondholders as holders of
Bonds in respect of which this Global Certificate is issued such amount or amounts as shall become due in respect of such Bonds and otherwise comply with the Conditions.

Payments

While this Global Certificate is held by the CMU Service,
principal and interest in respect of this Global Certificate shall be paid to the person(s) for whose account(s) interest(s) in this Global Certificate are credited as being held by the CMU Service in accordance with the CMU Rules. If this Global
Certificate is held by the CMU Service, payment of interest or principal shall be made by the CMU Lodging and Paying Agent to the person for whose account a relevant interest in this Global Certificate is credited as being held by the CMU Service at
the relevant time as notified to the CMU Lodging and Paying Agent by the CMU Service in a relevant CMU Instrument Position Report (as defined in the CMU Rules) or any other relevant notification by the CMU Service. For these purposes, a notification
from the CMU Service shall be conclusive evidence of the records of the CMU Service (save in the case of manifest error). So long as the Bonds are represented by the Global Certificate and is held by or on behalf of the CMU operator, such payment by
the Issuer will discharge the Issuers obligations in respect of that payment and such person(s) must look solely to the CMU operator for his share of each payment made by the Issuer or in respect of the Global Certificate and in relation to
all other rights arising under the Global Certificate, subject to and in accordance with the respective rules and procedures of









---

CMU, and such person(s) shall have no claim directly against the Issuer in respect of payments so made by the Issuer. No person shall however be entitled to receive any payment on this Global
Certificate (or such part of this Global Certificate which is required to be exchanged) falling due after any Exchange Date, unless exchange of this Global Certificate for Definitive Certificates is improperly withheld or refused by or on behalf of
the Issuer or the Issuer does not perform or comply with any one or more of what are expressed to be its obligations under any Definitive Certificates.

Each payment will be made to, or to the order of, the person(s) for whose account(s) interest(s) in this Global Certificate are credited as being held by the CMU Service in accordance with the CMU Rules
on each day on which the payment is due.

Exchange

This Global Certificate is exchangeable in whole but not, except as provided in the next paragraph, in part (free of charge to the holder) for the Definitive Certificates described below (1) if this
Global Certificate is held on behalf of the CMU or the Alternative Clearing System and any such clearing system is closed for business for a continuous period of 14 days (other than by reason of holidays, statutory or otherwise) or announces an
intention permanently to cease business or does in fact do so or (2) if principal in respect of any Bonds is not paid when due and payable. Thereupon the holder may give notice (which may but need not be the default notice referred to in
Events of Default below) to the Fiscal Agent of its intention to require the exchange of a specified principal amount of this Global Certificate (which may be equal to or less than the outstanding principal amount of Bonds represented
hereby) for Definitive Certificates on or after the Exchange Date (as defined below) specified in the notice.

On or after any Exchange Date
the holder of this Global Certificate may surrender this Global Certificate or, in the case of a partial exchange, present it for endorsement to or to the order of the Fiscal Agent. In exchange for this Global Certificate, or on endorsement in
respect of the part thereof to be exchanged, the Issuer shall deliver, or procure the delivery of, an equal aggregate principal amount of duly executed and authenticated Definitive Certificates in or substantially in the form set out in Part B of
Schedule 1 to the Fiscal Agency Agreement. Such Definitive Certificates shall be registered in such names as the holder shall direct in writing.

Exchange Date means a day falling not less than 30 days after that on which the notice requiring exchange is given and on which banks are open for business in Hong Kong and, in the case
of exchange pursuant to (1) above, Hong Kong or, if relevant, the city in which the Alternative Clearing System, is located.

The Issuer
shall procure that the Fiscal Agent will notify the Bondholders of the occurrence of any of the events specified above as soon as practicable thereafter.

If, for any actual or alleged reason which would not have been applicable had there been no exchange of this Global Certificate (or part of this Global Certificate) or in any other circumstances
whatsoever, the Issuer does not perform or comply with any one or more of what are expressed to be its obligations under any Definitive Certificates, then any right or remedy relating in any way to the obligation(s) in question may be exercised or
pursued on the basis of this Global Certificate despite its stated cancellation after its exchange in full, as if the Definitive Certificates had been issued. With this exception, upon exchange in full of this Global Certificate, this Global
Certificate shall become void.

Except as otherwise described herein, this Global Certificate is subject to the Conditions and, until it is
exchanged for Definitive Certificates, its holder shall in all respects be entitled to the same benefits as if it were the holder of the Definitive Certificates for which it may be exchanged and as if such Definitive Certificates had been issued on
the date of this Global Certificate.









---

This Global Certificate is evidence of entitlement only. Title to the Bonds passes only on due registration
in the register of Bondholders and only the duly registered holder is entitled to payments on the Bonds in respect of which this Global Certificate is issued.

The Conditions shall be modified with respect to Bonds represented by this Global Certificate by the following provisions:

Meetings

The registered holder of this Global Certificate (and any proxy or representative
appointed by it) will be treated as being two persons for the purposes of any quorum requirements of, or the right to demand a poll at, a meeting of Bondholders and in any such meeting as having one vote in respect of each CNY100,000 in principal
amount of Bonds evidenced by such Global Certificate.

Transfers

Transfers of the beneficial interests in the Bonds represented by this Global Certificate will be effected through the records of CMU, or any Alternative Clearing System and their respective participants
in accordance with the rules and operating procedures of CMU or any Alternative Clearing System and their respective participants.

Cancellation

Cancellation of any Bond
represented by this Global Certificate which is required by the Conditions to be cancelled will be effected by reduction in the principal amount of the Bonds in the register of Bondholders and this Global Certificate on its presentation to or to the
order of the Fiscal Agent for annotation (for information only) in Schedule A.

Events of Default

The holder hereof may exercise the right to declare Bonds represented by this Global Certificate due and payable under Condition 9 by stating in the
notice (the default notice) to the Fiscal Agent the principal amount of Bonds (which may be less than the outstanding principal amount hereof) to which such notice relates.

If principal in respect of any Bonds is not paid when due and payable (but subject as provided below), the holder of this Global Certificate may from time to time elect that Direct Rights under the
provisions of Schedule B shall come into effect. Such election shall be made by notice to the Fiscal Agent and presentation of this Global Certificate to or to the order of the Fiscal Agent for reduction of the principal amount of Bonds represented
by this Global Certificate by such figure as shall be specified in the notice by endorsement in Schedule A and the corresponding endorsement in Schedule B of such principal amount of Bonds formerly represented hereby as the principal amount of Bonds
in respect of which Direct Rights have arisen under Schedule B. Upon such notice being given the appropriate Direct Rights shall take effect.

No such election may however be made on or before an Exchange Date fixed in accordance with this Global Certificate with respect to the Bonds to which
that Exchange Date relates unless the holder elects in such notice that the exchange in question shall no longer take place.

Notices

So long as the Bonds are represented by this Global Certificate and this Global Certificate is held on behalf of CMU or any Alternative
Clearing System, notices to Bondholders may be given by delivery of the relevant notice to the persons shown in a CMU Instrument Position Report issued by the CMU or, as the case may be, the Alternative Clearing System rather than by publication as
required by the Conditions.









---

No provision of this Global Certificate shall alter or impair the obligation of the Issuer to pay the
principal and interest on the Bonds when due in accordance with the Conditions.

This Global Certificate shall not be valid or become
obligatory for any purpose until authenticated by or on behalf of the CMU Lodging and Paying Agent.

This Global Certificate shall be governed
by and construed in accordance with the laws of the State of New York, United States of America, without giving effect to the conflict of laws principles thereof.

Schedule 2

Terms and Conditions of the Bonds

TERMS AND CONDITIONS OF THE BONDS

The following other than the words in italics is the text of the terms and conditions of the Bonds which (subject to
modification) will appear on the reverse of each of the definitive certificates evidencing the Bonds:

The issue of the
Bonds was authorized by a resolution of the Board of Directors of the Issuer passed on March 12, 2013. A fiscal agency agreement (the Fiscal Agency Agreement) will be entered into on or about March 20, 2013 in relation
to the Bonds between the Issuer, Citicorp International Limited as fiscal agent, CMU lodging and paying agent, registrar and transfer agent, and the agents named in it. The fiscal agent, CMU lodging and paying agent, the registrar, and any transfer
agent for the time being are referred to below respectively as the Fiscal Agent, the CMU Lodging and Paying Agent, the Registrar, and the Transfer Agents.
Agents means the Fiscal Agent, the CMU Lodging and Paying Agent, the Registrar, the Transfer Agents and any other agent or agents appointed from time to time with respect to the Bonds. The Fiscal Agency Agreement includes the form
of the Bonds. Copies of the Fiscal Agency Agreement are available for inspection during normal business hours at the specified offices (as defined in the Fiscal Agency Agreement) of the Fiscal Agent, the Registrar and any Transfer Agents. The
holders of the Bonds (the Bondholders) are deemed to have notice of all the provisions of the Fiscal Agency Agreement applicable to them.

All capitalized terms that are not defined in these terms and conditions (the Conditions) will have the meanings given to them in the Fiscal Agency Agreement.



|1 | Form, Specified Denomination and Title
|- | --------------------------------------

The Bonds are issued in the specified denomination of RMB1,000,000 and higher integral multiples of RMB100,000.

The Bonds are represented by registered certificates (Certificates) and, save as provided in Condition 2(a), each Certificate shall represent the entire holding of Bonds by the
same holder.

Title to the Bonds shall pass only by registration in the register that the Issuer shall procure to be kept by
the Registrar in accordance with the provisions of the Fiscal Agency Agreement (the Register). Except as ordered by a court of competent jurisdiction or as required by law, the holder (as defined below) of any Bond shall be deemed
to be and may be treated as its absolute owner for all purposes whether or not it is overdue and regardless of any notice of ownership, trust or an interest in it, any writing on the Certificate representing it or the theft or loss of such
Certificate and no person shall be liable for so treating the holder.

In these Conditions, Bondholder and
holder means the person in whose name a Bond is registered.

Upon issue, the Bonds will be represented by
a global certificate (the Global Certificate) registered in the name of, and lodged with a sub-custodian for, the Hong Kong Monetary Authority as operator (the Operator) of the
Central Moneymarkets Unit Service (the CMU). The Conditions are modified by certain provisions contained in the Global Certificate. See Summary of Provisions Relating to the Bonds in Global Form.

Except in the limited circumstances described in the Global Certificate, owners of interests in Bonds represented by
the Global Certificate will not be entitled to receive definitive Certificates in respect of their individual holdings of Bonds. The Bonds are not issuable in bearer form.

So long as the Bonds are represented by the Global Certificate and the CMU so permits, transfers of interests in the Bonds through the CMU shall be in principal amounts of at least RMB1,000,000 and
higher integral multiples of RMB100,000 thereafter. Further, approval in-principle has been received for the listing and quotation of the Bonds on the Official List of the Singapore Exchange Securities Trading Limited









---

(the SGX-ST). The Bonds will be traded on the SGX-ST in a minimum board lot size of RMB500,000 with a minimum of four lots to be traded in a single transaction
for as long as the Bonds are listed on the SGX-ST.



|2 | Transfers of Bonds
|- | ------------------



| | (a) | Transfer:A holding of Bonds may, subject to Condition 2(d), be transferred in whole or in part upon the surrender (at the specified office of the Registrar or
any Transfer Agent) of the Certificate(s) representing such Bonds to be transferred, together with the form of transfer endorsed on such Certificate(s) (or another form of transfer substantially in the same form and containing the same
representations and certifications (if any), unless otherwise agreed by the Issuer), duly completed and executed and any other evidence as the Registrar or Transfer Agent may reasonably require. In the case of a transfer of part only of a holding of
Bonds represented by one Certificate, a new Certificate shall be issued to the transferee in respect of the part transferred and a further new Certificate in respect of the balance of the holding not transferred shall be issued to the transferor. In
the case of a transfer of Bonds to a person who is already a holder of Bonds, a new Certificate representing the enlarged holding shall only be issued against surrender of the Certificate representing the existing holding. All transfers of Bonds and
entries on the Register will be made in accordance with the detailed regulations concerning transfers of Bonds scheduled to the Fiscal Agency Agreement. The regulations may be changed by the Issuer, with the prior written approval of the Registrar
and the Fiscal Agent. A copy of the current regulations will be made available by the Registrar to any Bondholder upon request.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Transfers of interests in the Bonds evidenced by the Global Certificate will be effected in accordance with the rules of the CMU.



| | (b) | Delivery ofNew Certificates:Each new Certificate to be issued pursuant to Condition 2(a) shall be available for delivery within three business
days of receipt of a duly completed form of transfer and surrender of the existing Certificate(s). Delivery of the new Certificate(s) shall be made at the specified office of the Transfer Agent or of the Registrar (as the case may be) to whom
delivery or surrender of such form of transfer or Certificate shall have been made or, at the option of the holder making such delivery or surrender as aforesaid and as specified in the relevant form of transfer or otherwise in writing, be mailed by
uninsured post at the risk of the holder entitled to the new Certificate to such address as may be so specified, unless such holder requests otherwise and pays in advance to the relevant Transfer Agent or the Registrar (as the case may be) the costs
of such other method of delivery and/ or such insurance as it may specify. In this Condition 2(b). business day means a day, other than a Saturday or Sunday, on which banks are open for business in the place of the specified
office of the relevant Transfer Agent or the Registrar (as the case may be).

| | (c) | Transfer or Exercise Free of Charge: Certificates, on transfer, or partial repurchase, shall be issued and registered without charge by or on behalf of the
Issuer, the Registrar or any Transfer Agent, but upon payment of any tax or other governmental charges that may be imposed in relation to it (or the giving of such indemnity as the Registrar or the relevant Transfer Agent may require).
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Closed Periods:No Bondholder may require the transfer of a Bond to be registered (i) during the period of 15 days ending on (and including) the due date
for redemption of that Bond, (ii) during the period of 15 days ending on (and including) the date of redemption pursuant to Condition 6(b). or (iii) during the period of seven days ending on (and including) any Record Date (as defined in
Condition 7). No Bondholder who has properly tendered the Bonds in accordance with Condition 6(c) may require the transfer of a Bond to be registered during the period of 15 days ending on (and including) a Change of Control Payment Date.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3 | Status
|- | ------

constitute (subject to Condition 4(a)) unsecured obligations of the Issuer and shall at all times rank pari passu and without any preference among themselves. The payment obligations of the Issuer under









---

as any Bond remains outstanding (as defined in the Fiscal Agency Agreement), the Issuer will not, and will ensure that none of its Subsidiaries will create, or have outstanding, any Security upon the whole or any part of its present or future
undertaking, assets or revenues (including any uncalled capital) to secure any Relevant Indebtedness, or any guarantee or indemnity in respect of any Relevant Indebtedness, without at the same time or prior thereto according to the Bonds the same
security as is created or subsisting to secure any such Relevant Indebtedness, guarantee or indemnity or such other security as shall be approved by an Extraordinary Resolution (as defined in the Fiscal Agency Agreement) of the Bondholders.

of doubt, the obligation to pay additional amounts as set forth in Condition 8); and (ii) immediately after giving effect to such transaction, no default or event of default has occurred and is continuing under the Bonds. Upon any such

reasonable measure), provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Tax Amounts were a payment in respect of the Bonds then due.
Prior to the publication of any notice of redemption pursuant to this Condition 6(b), the Issuer shall deliver to the Fiscal Agent a certificate signed by two directors of the Issuer stating that the Issuer is entitled to effect such redemption and
setting forth a statement of facts showing that the conditions precedent to the right of the Issuer so to redeem have occurred, and an opinion of independent legal advisers of recognized standing to the effect that the Issuer has or will become
obliged to pay such Additional Tax Amounts as a result of such change or amendment.



| | (c) | Repurchase Upon Change of Control:
| | --- | ----------------------------------

If a Change of Control occurs, unless the Issuer has exercised its right to redeem the Bonds as described above in Condition 6(b), it will be required to make an offer to repurchase all or, at the









---

holders option, any part (equal to RMB1,000,000 or multiples of RMB100,000 in excess thereof), of each holders Bonds pursuant to the offer described below (the Change of
Control Offer), provided that a holder may not exercise its option to require the Issuer to make an offer to repurchase the Bonds in part if it would result in the principal amount of any unpurchased portion of the Bonds held by such
holder to be less than RMB1,000,000. In the Change of Control Offer, the Issuer will be required to offer payment in cash equal to 101% of the aggregate principal amount of the Bonds repurchased plus accrued and unpaid interest, if any, on the Bonds
repurchased to, but not including, the date of purchase (the Change of Control Payment).

Within 30 days
following any Change of Control, the Issuer will be required to give notice to holders of the Bonds, describing the transaction or transactions that constitute the Change of Control and offering to repurchase the Bonds on the date specified in the
notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the Change of Control Payment Date), pursuant to the procedures required by the Bonds and described in such notice.

On the Change of Control Payment Date, the Issuer will be required, to the extent lawful, to:



| | (a) | accept for payment all Bonds properly tendered pursuant to the Change of Control Offer; and
| | --- | -------------------------------------------------------------------------------------------



| | (b) | deposit with the relevant Agents an amount equal to the Change of Control Payment in respect of all Bonds properly tendered;
| | --- | ----------------------------------------------------------------------------------------------------------------------------

The relevant Agents will be required to promptly mail, to each holder who properly tendered the Bonds, the purchase price for such Bonds
properly tendered, and the Fiscal Agent will be required to promptly authenticate and mail (or cause to be transferred by book-entry) to each such holder a new Bond equal in principal amount to any unpurchased portion of the Bonds surrendered, if
any: provided that each new Bond will be in a principal amount of RMB1,000,000 or a multiple of RMB100,000 in excess thereof.

The Issuer will not be required to make a Change of Control Offer upon a Change of Control 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 Issuer and such third party purchases all Bonds properly tendered and not withdrawn under its offer. In the event that such third party terminates or
defaults its offer, the Issuer will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control.

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act (as defined in Condition 4 (c)), 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 Bonds as a result of a Change of Control. To the extent that the provision of any
such securities laws or regulations conflicts with the Change of Control Offer provisions of the Bonds, the Issuer will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of
Control Offer provisions of the Bonds by virtue of any such conflict. A tender agent may be appointed to assist with the Repurchase Upon Change of Control when it happens. The Fiscal Agent may act as the tender agent.

of which the Issuer cannot obtain sufficient Renminbi in order to satisfy its obligation to pay interest or principal in respect of the Bonds as determined by the Issuer in good faith and in a commercially reasonable manner following consultation
with two Renminbi Dealers.

Inconvertibility means the occurrence of any event that makes it impossible
(where it had previously been possible) for the Issuer to convert any amount due in respect of the Bonds in the general Renminbi exchange market in Hong Kong, other than where such impossibility is due solely to the failure of the Issuer to comply
with any law, rule or regulation enacted by any Governmental Authority (unless such law, rule or regulation is enacted after March 15, 2013 and it is impossible for the Issuer, due to an event beyond its control, to comply with such law, rule
or regulation).

Non-transferability means the occurrence of any event that makes it impossible for the
Issuer to transfer Renminbi between accounts inside Hong Kong or from an account inside Hong Kong to an account outside Hong Kong, other than where such impossibility is due solely to the failure of the Issuer to comply with any law, rule or
regulation enacted by any Governmental Authority (unless such law, rule or regulation is enacted after March 15, 2013 and it is impossible for the Issuer, due to an event beyond its control, to comply with such law, rule or regulation).

Renminbi Dealer means an independent foreign exchange dealer of international reports active in the
Renminbi exchange market in Hong Kong.

Spot Rate means the RMB/U.S. Dollar official fixing rate, expressed
as the amount of RMB per one U.S. Dollar, for settlement in two Determination Business Days reported by the Treasury Markets Association which appears on Reuters Screen page <TRADCNY3> at approximately 11:00 a.m. (Hong Kong
time) or if no such rate is available, on a non-deliverable basis by reference to Reuters Screen page <TRADNDF>.

If
neither rate is available, the Fiscal Agent will determine the Spot Rate at or around 11.00 a.m. (Hong Kong time) on the Determination Date as the most recently available RMB/U.S. dollar official fixing rate for settlement in two Determination
Business Days reported by The State Administration of Foreign Exchange of the PRC, which is reported on the Reuters Screen Page CNY=SAEC. Reference to a page on the Reuters Screen means the display page so designated on the Reuter Monitor Money
Rates Service (or any successor service) or such other screen page as may replace that page for the purpose of displaying a comparable currency exchange rate.

All notifications, opinions, determinations, certificates, calculations, quotations and decisions given, expressed, made or obtained for the purposes of the provisions of this Condition 7(g) by the Fiscal
Agent, will (in the absence of wilful default, bad faith or manifest error) be binding on the Issuer, the Agents and all Bondholders.



|8 | Taxation
|- | --------

All payments of
principal, premium and interest by or on behalf of the Issuer in respect of the Bonds shall be made free and clear of, and without withholding or deduction for, any taxes, duties, assessments or governmental charges of whatever nature imposed,
levied, collected, withheld or assessed by or within the United States of America, the Cayman Islands or the PRC or any authority therein or thereof having power to tax (each a Relevant Jurisdiction), unless such withholding or
deduction is required by law.

If the Issuer is required to make a deduction or withholding in respect of tax of a Relevant
Jurisdiction, the Issuer shall pay such additional amounts (Additional Tax Amounts) as will result in receipt by the Bondholders of such amounts as would have been received by them had no such withholding or deduction been
required, except that no Additional Tax Amounts shall be payable in respect of any Bond:









---

| | (a) | for or on account of:
| | --- | ---------------------



| | (1) | any taxes that would not have been imposed but for:
| | --- | ---------------------------------------------------



| | a) | the existence of any present or former connection between the holder or beneficial owner of such Bond, as the case may be, and the Relevant Jurisdiction, including
without limitation, such holder or beneficial owner being or having been a citizen or resident of the Relevant Jurisdiction, being or having been treated as a resident of the Relevant Jurisdiction, being or having been present or engaged in a trade
or business in the Relevant Jurisdiction or having or having had a permanent establishment in the Relevant Jurisdiction, other than merely holding such Bond or the receipt of payments thereunder;
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | the failure of the holder or beneficial owner of such Bond to comply with a timely request of the Issuer addressed to such holder or beneficial owner to provide
information concerning such holders or beneficial owners nationality, residence, identity or connection with the Relevant Jurisdiction;
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | the presentation of such Bond (where presentation is required) more than 30 days after the later of the date on which the payment of the principal of, or interest on,
such Bond, as applicable, became due and payable pursuant to the terms thereof or was made or duly provided for, except to the extent that the holder thereof would have been entitled to such Additional Tax Amounts if it had presented such Bond for
payment on any date within such 30-day period; or
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d) | the presentation of such Bond (where presentation is required) for payment in the Relevant Jurisdiction, unless such Bond could not have been presented for payment
elsewhere;
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | any estate, inheritance, gift, sale, transfer, excise, personal property, net income or similar tax;
| | --- | ----------------------------------------------------------------------------------------------------



| | (3) | any withholding or deduction where such withholding or deduction is imposed or levied on a payment to an individual and is required to be made pursuant to European
Council Directive 2003/48/EC (or any amendment thereof) or any other Directive (or any amendment thereof) implementing the conclusions of the ECOFIN Council meeting of 26-November 27, 2000 on the taxation of savings income or any law
implementing or complying with, or introduced in order to conform to, such Directives or amendments;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (4) | any taxes that are payable other than by withholding or deduction from payments of principal of, or interest on, the Bonds; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------



| | (5) | any combination of taxes referred to in the preceding clauses (1),(2), (3) and (4); or
| | --- | --------------------------------------------------------------------------------------



| | (b) | with respect to any payment of the principal of, or interest on, such Bond to or for the account of a fiduciary, partnership or other fiscally transparent entity or any
other person (other than the sole beneficial owner of such payment) to the extent that a beneficiary or settlor with respect to that fiduciary, or a partner or member of that partnership or fiscally transparent entity or a beneficial owner with
respect to such other person, as the case may be, would not have been entitled to such additional amounts had such beneficiary, settlor, partner, member or beneficial owner held directly the Bond with respect to which such payment was made.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any reference in these Conditions to principal or interest shall be deemed to include any additional amounts in
respect of principal or interest (as the case may be) which may be payable under this Condition 8 or any undertaking given in addition to or in substitution of this Condition 8.

and/or any such significant subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity (including, without

Issuer or any of its significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X, or all or substantially all of the property and assets of the Issuer or any of its significant subsidiaries, as defined in Article 1, Rule 1-02 of
Regulation S-X, and such involuntary case or other proceeding remains undismissed and unstayed for a period of 60 consecutive days; or an order for relief is entered against the Issuer or any of its significant subsidiaries, as defined in Article 1,
Rule 1-02 of Regulation S-X, under any applicable bankruptcy, insolvency or other similar law as now or hereafter in effect;

| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If an Event of Default occurs and is continuing, then any Bond may, by notice in writing given to the Fiscal Agent at its specified office by the holder, be declared immediately due and payable whereupon
it shall become immediately due and payable at its principal amount together with accrued interest without further formality unless such Event of Default shall have been remedied prior to the receipt of such notice by the Fiscal Agent.









---

For the avoidance of doubt, each of our consolidated affiliated entities will be deemed to
be a subsidiary for purposes of the definition of significant subsidiary in Article 1, Rule 1-02 of Regulation S-X.



|10 | Prescription
|-- | ------------

Claims
against the Issuer for payment in respect of the Bonds shall be prescribed and become void unless made within 10 years (in the case of principal) or five years (in the case of interest) from the date on which the payment in question first becomes
due.



|11 | Replacement of Certificates
|-- | ---------------------------

If any Certificate is lost, stolen, mutilated, defaced or destroyed, it may be replaced, subject to applicable laws, regulations or other relevant regulatory authority regulations, at the specified office
of the Registrar or such other Transfer Agent as may from time to time be designated by the Issuer for that purpose and notice of whose designation is given to Bondholders, in each case on payment by the claimant of the fees and costs incurred in
connection therewith and on such terms as to evidence, security, indemnity and otherwise as the Issuer may require (provided that the requirement is reasonable in light of prevailing market practice). Mutilated or defaced Certificates must be
surrendered before replacements will be issued.



|12 | Meetings of Bondholders, and Modification
|-- | -----------------------------------------



| | (a) | Meetings of Bondholders: The Fiscal Agency Agreement contains provisions for convening meetings of Bondholders to consider matters affecting their interests,
including the sanctioning by Extraordinary Resolution of a modification of any of these Conditions. Such a meeting may be convened by Bondholders holding not less than 10 per cent in principal amount of the Bonds for the time being outstanding. The
quorum for any meeting convened to consider an Extraordinary Resolution will be two or more persons holding or representing a clear majority in principal amount of the Bonds for the time being outstanding, or at any adjourned meeting two or more
persons being or representing Bondholders whatever the principal amount of the Bonds held or represented, unless the business of such meeting includes consideration of proposals, inter alia,(i) to modify the maturity of the Bonds or the
dates on which interest is payable in respect of the Bonds, (ii) to reduce or cancel the principal amount of, any premium payable on redemption of, or interest on, the Bonds, (iii) to change the currency of payment of the Bonds, or
(iv) to modify the provisions concerning the quorum required at any meeting of Bondholders or the majority required to pass an Extraordinary Resolution, in which case the necessary quorum will be two or more persons holding or representing not
less than 66 per cent, or at any adjourned meeting not less than 25 per cent, in principal amount of the Bonds for the time being outstanding. Any Extraordinary Resolution duly passed shall be binding on Bondholders (whether or not they
were present at the meeting at which such resolution was passed).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Fiscal Agency Agreement provides that a
resolution in writing signed by or on behalf of the holders of not less than 75% in principal amount of the Bonds outstanding shall for all purposes be as valid and effective as an Extraordinary Resolution passed at a meeting of Bondholders duly
convened and held. Such a resolution in writing may be contained in one document or several documents in the same form, each signed by or on behalf of one or more Bondholders.



| | (b) | Modification of the Fiscal Agency Agreement: The Issuer shall only permit any modification of, or any waiver or authorization of any breach or proposed breach of
or any failure to comply with, the Fiscal Agency Agreement, if to do so could not reasonably be expected to be materially prejudicial to the interests of the Bondholders.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|13 | Further Issues
|-- | --------------

The
Issuer may from time to time without the consent of the Bondholders create and issue further securities either having the same terms and conditions as the Bonds in all respects (or in all respects except for the first payment of interest on them)
and so that such further issue shall be consolidated and form a single series









---

with the outstanding securities of any series (including the Bonds) or upon such terms as the Issuer may determine at the time of their issue. References in these Conditions to the Bonds include
(unless the context requires otherwise) any other securities issued pursuant to this Condition and forming a single series with the Bonds.



|14 | Notices
|-- | -------

Notices to the
holders of Bonds shall be mailed to them at their respective addresses in the Register and deemed to have been given on the fourth weekday (being a day other than a Saturday or a Sunday) after the date of mailing. The Issuer shall also ensure that
notices are duly published in a manner that complies with the rules and regulations of any stock exchange or other relevant authority on which the Bonds are for the time being listed. Any such notice shall be deemed to have been given on the date of
such publication or, if published more than once, on the first date on which publication is made.



|15 | Currency Indemnity
|-- | ------------------

Subject to Condition 7(g), the Renminbi is the sole currency of account and payment for all sums payable by the Issuer under or in
connection with the Bonds, including damages. Any amount received or recovered in a currency other than Renminbi (whether as a result of, or of the enforcement of, a judgment or order of a court of any jurisdiction, in the insolvency, winding-up or
dissolution of the Issuer or otherwise) by any Bondholder in respect of any sum expressed to be due to it from the Issuer shall only constitute a discharge to the Issuer to the extent of the Renminbi amount which the recipient is able to purchase
with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so). If that Renminbi amount
is less than the Renminbi amount expressed to be due to the recipient under any Bond, the Issuer shall indemnify it against any loss sustained by it as a result. In any event, the Issuer shall indemnify the recipient against the cost of making any
such purchase. For the purposes of this Condition, it will be sufficient for the Bondholder to demonstrate that it would have suffered a loss had an actual purchase been made. These indemnities constitute a separate and independent obligation from
the Issuers other obligations, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any Bondholder and shall continue in full force and effect despite any other judgment, order,
claim or proof for a liquidated amount in respect of any sum due under any Bond or any other judgment or order.



|16 | Governing Law and Jurisdiction
|-- | ------------------------------



| | (a) | Governing Law: The Fiscal Agency Agreement and the Bonds are governed by, and shall be construed in accordance with, the laws of the State of New York, United
States of America, without giving effect to the conflict of laws principles thereof.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Jurisdiction: The courts of the State of New York and the United States District Court located in the Borough of Manhattan in New York City are to have
jurisdiction to settle any legal action or proceedings arising out of or in connection with any Bonds (Proceedings) and accordingly any Proceedings may be brought in such courts. The Issuer irrevocably submits to the jurisdiction
of the courts of the State of New York and the United States District Court located in the Borough of Manhattan in New York City and waives any objection to Proceedings in such courts whether on the ground of venue or on the ground that the
Proceedings have been brought in an inconvenient forum. This submission is made for the benefit of the holders of the Bonds and shall not affect the right of any of them to take Proceedings against the Issuer in any other court of competent
jurisdiction nor shall the taking of Proceedings in one or more jurisdictions preclude any of them from taking Proceedings in any other jurisdiction (whether concurrently or not).
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------









---

| | (c) | Agent for Service of Process: The Issuer irrevocably appoints Law Debenture Corporate Services Inc., with offices at 400 Madison Avenue, 4th Floor, New York, New
York 10017 as its agent to receive service of process in any Proceedings in the State of New York based on any of the Bonds. If for any reason the Issuer does not have such an agent in the State of New York, it will promptly appoint a substitute
process agent and notify the Bondholders of such appointment. Nothing herein shall affect the right to serve process in any other manner permitted by law.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|11 | The chairman may with the consent of (and shall if directed by) a meeting adjourn the meeting from time to time and from place to place. Only business which
could have been transacted at the original meeting may be transacted at a meeting adjourned in accordance with this paragraph or paragraph 9.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12 | At least 10 days notice of a meeting adjourned through want of a quorum shall be given in the same manner as for an original meeting and that notice shall
state the quorum required at the adjourned meeting. No notice need, however, otherwise be given of an adjourned meeting.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Voting



|13 | Each question submitted to a meeting shall be decided by a show of hands unless a poll is (before, or on the declaration of the result of, the show of hands)
demanded by the chairman, the Issuer or one or more persons representing two per cent. of the Bonds.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|14 | Unless a poll is demanded, a declaration by the chairman that a resolution has or has not been passed shall be conclusive evidence of the fact without proof of
the number or proportion of the votes cast in favor of or against it.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|15 | If a poll is demanded, it shall be taken in such manner and (subject as provided below) either at once or after such adjournment as the chairman directs. The
result of the poll shall be deemed to be the resolution of the meeting at which it was demanded as at the date it was taken. A demand for a poll shall not prevent the meeting continuing for the transaction of business other than the question on
which it has been demanded.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|16 | A poll demanded on the election of a chairman or on a question of adjournment shall be taken at once.
|-- | -----------------------------------------------------------------------------------------------------



|17 | On a show of hands every person who is present in person and who produces a Bond or is a proxy has one vote. On a poll every such person has one vote for
CNY100,000 in principal amount of Bonds so produced or for which he is a proxy or representative. Without prejudice to the obligations of proxies, a person entitled to more than one vote need not use them all or cast them all in the same way.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|18 | In case of equality of votes the chairman shall both on a show of hands and on a poll have a casting vote in addition to any other votes which he may have.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------

Effect and Publication of an Extraordinary Resolution



|19 | An Extraordinary Resolution shall be binding on all the Bondholders, whether or not present at the meeting, and each of them shall be bound to give effect to it
accordingly. The passing of such a resolution shall be conclusive evidence that the circumstances justify its being passed. The Issuer shall give notice of the passing of an Extraordinary Resolution to Bondholders within 14 days but failure to do so
shall not invalidate the resolution.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Minutes



|20 | Minutes shall be made of all resolutions and proceedings at every meeting and, if purporting to be signed by the chairman of that meeting or of the next
succeeding meeting, shall be conclusive evidence of the matters in them. Until the contrary is proved every meeting for which minutes have been so made and signed shall be deemed to have been duly convened and held and all resolutions passed or
proceedings transacted at it to have been duly passed and transacted.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Written Resolutions



|21 | A written resolution signed by the holders of 75% in principal amount of the Bonds outstanding shall take effect as if it were an Extraordinary Resolution. Such
a resolution in writing may be contained in one document or several documents in the same form, each signed by or on behalf of one or more Bondholders.
