(a) | Security

The obligations of the Issuer and the Guarantor to the Bondholders under the Bonds and in connection with the Transaction Documents and the Security Documents (the “Secured Obligations”) will be secured by:

| (i) | the security interest over 1,393,207 Class B ordinary shares representing 5.0 per cent. of the total authorised and issued Ordinary Shares of the Issuer as of the Issue Date granted by the Guarantor pursuant to the Share Charge; and

| (ii) | the security interest granted by the Issuer over the Debt Service Reserve Account pursuant to the Account Charge.

(b) | Release of Security

The Security Documents contain provisions for the immediate release of all or any security interests created therein or discharge in full of the Secured Obligations.

(c) | Enforcement of Security

| (i) | Subject to an Event of Default under the Conditions and in accordance with the Security Documents, the Share Charge and/or the Account Charge, as the case may be, shall become enforceable upon the Bonds becoming immediately due and repayable following the occurrence of an Event of Default.

| (ii) | Any Bondholder may, at its discretion and without further notice, take such proceedings against the Issuer and/or the Guarantor as it may think fit to enforce its rights under the Bonds and to enforce all or any of the security interests created therein in accordance with the terms thereof, provided that, to the extent practicable the Bondholders shall enforce their rights under the Account Charge prior to enforcing their rights under the Share Charge.

6. | Interest

(a) | Interest

The Bonds bear interest from and including the Issue Date at the rate of 8.00 per cent. per annum (the “Rate of Interest”) payable semi-annually in arrear in equal instalments of US$10,000 per Calculation Amount (as defined below) (the “Interest Amount”) on the date falling on the 6th calendar month following the Issue Date (the “First Interest Payment Date”) and the date falling on the 12th calendar month following the Issue Date, and if the Maturity Date is extended to the Extended Maturity Date, on the date falling on the 18th calendar month following the Issue Date, and if any such date is not a Business Day, the next following Business Day (each an “Interest Payment Date”).

Each Bond will cease to bear interest from and including the earlier of (a) where the Conversion Right attached to it shall have been exercised by a Bondholder, the relevant Conversion Date (as defined below), subject to conversion of the relevant Bonds in accordance with the provisions of Condition 7(c); or (b) where such Bond is redeemed or repaid pursuant to Condition 9 or Condition 11, the due date for redemption or repayment thereof unless, upon due presentation thereof, payment of principal is improperly withheld or refused.

If interest is required to be calculated for a period of less than a complete Interest Period, the relevant day-count fraction will be determined on the actual number of days elapsed and on the basis of a 360-day year.

1-11

In these Conditions, the period beginning on and including the Issue Date and ending on but excluding the first Interest Payment Date (the “First Interest Period”) and each successive period beginning on and including an Interest Payment Date and ending on but excluding the next succeeding Interest Payment Date is called an “Interest Period”, provided that any Interest Period (other than a Default Interest Period) shall end on the Maturity Date.

Interest in respect of any Bond shall be calculated per US$250,000 in principal amount of the Bonds (the “Calculation Amount”). The amount of interest payable per Calculation Amount for any period shall, save as provided above in relation to equal instalments, be equal to the product of 8.00 per cent. per annum, the Calculation Amount and the day-count fraction (determined in the same manner as stated above in this Condition 6) for the relevant period, rounding the resulting figure to the nearest cent (US$0.005 being rounded upward).

(b) | Interest applicable upon Default

Following service of a Notice of Event of Default on the Issuer and the Guarantor, the Issuer (failing whom, the Guarantor) shall pay to the Bondholders:

| (i) | if any such Event of Default occurs on or before the date falling 12 calendar months after the Issue Date:

| (A) | an amount of premium that would give the Bondholders an internal rate of return equal to the Exit IRR calculated by reference to the principal amount of the Outstanding Bonds from (and including) the Issue Date up to (but excluding) the Scheduled Maturity Date; and

| (B) | an amount of premium that would give the Bondholder an internal rate of return equal to the 15.0 per cent. per annum calculated by reference to the principal amount of the Outstanding Bonds from (and including) the earliest of (X) the date of a Notice of Potential Event of Default (if any), (Y) the date of any such proceedings referred to in Condition 11(v) is being levied, enforced or sued out on (if applicable), and (Z) an Event of Default up to (but excluding) the day on which all sums due in respect of the Bonds (which shall include sums due under this Condition 6(b)) are received by the Holders (the “Default Interest Period”); or

| (ii) | if any such Event of Default occurs after the date falling 12 calendar months after the Issue Date:

| (A) | an amount of premium that would give the Bondholders an internal rate of return equal to the Exit IRR calculated by reference to the principal amount of the Outstanding Bonds from (and including) the Issue Date up to (but excluding) the earliest of (X) the date of a Notice of Potential Event of Default (if any), (Y) the date of any such proceedings referred to in Condition 11(v) is being levied, enforced or sued out on (if applicable), and (Z) an Event of Default; and

| (B) | an amount of premium that would give the Bondholder an internal rate of return equal to the Default IRR calculated by reference to the principal amount of the Outstanding Bonds from (and including) the earliest of (X) the date of a Notice of Potential Event of Default (if any), (Y) the date of any such proceedings referred to in Condition 11(v) is being levied, enforced or sued out on (if applicable), and (Z) an Event of Default, up to (and excluding) the end of the Default Interest Period.

The Exit IRR, the Default IRR and the premium provided in Condition 6(b)(i)(B) above shall take into account any principal, interest (including Interest Amount) and premium accrued on the Outstanding Bonds and paid to the Bondholders, but exclude any Structuring Fee payable by the Issuer to the initial Bondholders as provided in the Subscription Agreement.

No interest shall accrue on any Bond from and including the Conversion Date in respect of such Bond.

1-12

7. | Conversion

(a) | Partial Conversion upon a QIPO

Provided that none of the Bonds has been redeemed by the Issuer, upon the occurrence of a QIPO and subject as provided in these Conditions:

| (i) | an aggregate nominal amount representing 10% of the Principal Amount of the Bonds shall be converted automatically into Shares (the “Conversion Upon QIPO”); and

| (ii) | the Issuer shall deliver a written notice in accordance with Condition 13 to notify the Bondholders, together with such evidence provided by an Independent Investment Bank to support, that the QIPO has occurred as provided in the Conditions. Upon the receipt of such notice, a Bondholder shall as soon as practicable deliver to the Issuer a written notice in accordance with Condition 13 (the “Certification”) on behalf of itself:

| (A) | providing an address (if different from the corresponding addresses recorded in the Register) to which the Shares shall be delivered;

| (B) | designating a person or persons (if different from the registered Holder) as holder(s) of the relevant number of Shares in the Issuer’s share register;

| (C) | providing a certification that such Conversion Upon QIPO is being made outside of the United States (as such term is defined in Regulation S (“Regulation S”) under the United States Securities Act of 1933, as amended) and it is not a U.S. person (as such term is defined in Regulation S) and it is not acting as agent for, or on behalf of, a U.S. person;

| (D) | providing any certification as may be required under the laws of the jurisdiction of incorporation of the Issuer; and

| (E) | surrendering the Bond Certificate in respect of such Bond which shall be converted automatically into Shares as a result of the occurrence of a QIPO.

(b) | Conversion Right

| (i) | Conversion Period: Upon the occurrence of a QIPO and subject as provided in these Conditions, each Bond shall entitle the holder to convert such Bond into Shares credited as fully paid at any time during the Conversion Period referred to below (the “Conversion Right”).

Subject to and upon compliance with these Conditions, the Conversion Right in respect of a Bond may be exercised, at the option of the holder thereof, on the occurrence of a QIPO at any time (subject to any applicable fiscal or other laws or regulations and as hereinafter provided) on or after the Issue Date to the earlier of:

| (A) | the date falling 12 calendar months after the Maturity Date or the Extended Maturity Date, as the case may be (both days inclusive); and

| (B) | the date falling 12 calendar months after the occurrence of the QIPO (both days inclusive),

(each a “Conversion Period”).

1-13

| (ii) | A Bondholder may only exercise its Conversion Right during the Conversion Period.
| (iii) | Conversion Price: The price at which Shares will be issued upon a Conversion Upon QIPO or exercise of a Conversion Right (the “Conversion Price”) is subject to any adjustment in the circumstances described in Condition 7(d) and the discount (if applicable) to the IPO Share Price as follows:

| (A) | if a QIPO has occurred on or before the date falling 12 calendar months after the Issue Date, at a discount of 23.0% to the IPO Share Price pursuant to the QIPO; or

| (B) | if a QIPO has occurred after the date falling 12 calendar months after the Issue Date, at a discount of 28.0% to the IPO Share Price pursuant to the QIPO,

in each case subject to adjustment in the circumstances described in Condition 7(d).

In the event that any Interest Amount has been accrued and/or paid by the Issuer to the Bondholders prior to the occurrence of the QIPO, in determining the applicable Conversion Price, 50.0 per cent. of such Interest Amount accrued and/or paid will be deducted from the absolute value of the discount as calculated in accordance with Conditions 7(b)(iii)(A) or 7(b)(iii)(B) above (as applicable). Schedule 5 sets out certain possible circumstances of the application of the discounts described herein for illustrative purposes only.

| (iv) | The number of Shares to be issued on Conversion Upon QIPO or exercise of a Conversion Right shall be determined by dividing the principal amount of the Bonds to be converted by the Conversion Price in effect on the relevant Conversion Date (defined below). Conversion Upon QIPO may only be effected and a Conversion Right may only be exercised in respect of one or more Bonds. If more than one Bond held by the same holder is converted at any one time by the same holder, the number of Shares to be issued upon such conversion will be calculated on the basis of the aggregate principal amount of the Bonds to be converted.

| (v) | Fractions of Shares: Fractions of Shares will not be issued on exercise of Conversion Rights and no cash payment or other adjustment will be made in lieu thereof. However, if the Conversion Right in respect of more than one Bond is exercised at any one time such that Shares to be issued on conversion are to be registered in the same name, the number of such Shares to be issued in respect thereof shall be calculated on the basis of the aggregate principal amount of such Bonds being so converted and rounded down to the nearest whole number of Shares. Notwithstanding the foregoing, in the event of a consolidation or re-classification of Shares by operation of law or otherwise occurring after the Issue Date which reduces the number of Shares outstanding, the Issuer will upon conversion of Bonds pay in cash in U.S. Dollars a sum equal to such portion of the principal amount of the Bond or Bonds evidenced by the Bond Certificate deposited in connection with the exercise of Conversion Rights, aggregated as provided in Condition 7(b)(i), as corresponds to any fraction of a Share not issued as a result of such consolidation or re-classification aforesaid, provided that such sum exceeds US$1.00. Any such sum shall be paid not later than five Business Days after the relevant Conversion Date by transfer to a U.S. dollar account maintained by the payee with, a bank in Hong Kong, in accordance with instructions given by the relevant Bondholder in the Conversion Notice.

| (vi) | Share Lockup Period: Provided that no Event of Default has occurred and is continuing, following the exercise of the Conversion Right by a Bondholder, such Bondholder shall not, directly or indirectly, sell or otherwise transfer any Shares during a period of up to 90 calendar days following the first Trading Day after the occurrence of a QIPO (the “Share Lockup Period”).

1-14

Subject to the Share Lockup Period provided above, the Bondholders may sell or transfer the Shares resulting from conversion of the Bonds. The Issuer shall register the Shares in the registration statement on the Form F-1 which it will submit to the U.S. Securities and Exchange Commission for the purpose of the intended QIPO.

(c) | Conversion Procedure

| (i) | Conversion Notice: Subject to Condition 7(a), Conversion Rights may be exercised by a Bondholder during the Conversion Period, by delivering the relevant Bond Certificate to the Issuer during its usual business hours (being 9:00 a.m. to 5:00 p.m., Monday to Friday other than public holidays) at the specified office of the Issuer accompanied by a duly completed and signed notice of conversion (a “Conversion Notice”) substantially in the form set out in schedule 4 hereto, together with certification by the Bondholder that such conversion is being made outside of the United States (as such term is defined in Regulation S) and it is not a U.S. person (as such term is defined in Regulation S) and it is not acting as agent for, or on behalf of, a U.S. person, and as may be required under the laws of the jurisdiction of incorporation of the Issuer. Conversion Rights shall be exercised subject in each case to any applicable fiscal or other laws or regulations applicable in the jurisdiction of the Issuer.

If such delivery is made after the end of normal business hours (being 5.00 p.m. in the place of the specified office) or on a day which is not a Business Day in the place of the Issuer, such delivery shall be deemed for all purposes of these Conditions to have been made on the next following such Business Day.

| (ii) | Conversion Date: For the purposes of Conversion Upon QIPO and exercise of Conversion Rights, the conversion date in respect of a Bond (the “Conversion Date”) shall be deemed to be the Business Day (as defined in Condition 7(h)) immediately following the date of the surrender of the Bond Certificate in respect of such Bond and delivery of such Conversion Notice or Certification, as the case may be, and, if applicable, any such abovementioned certification or any payment to be made or indemnity given under these Conditions in connection with the Conversion Upon QIPO and the exercise of such Conversion Right, as the case may be. Conversion Upon QIPO may only be effected and Conversion Rights may only be exercised in respect of an Authorised Denomination. A Conversion Notice or Certification, as the case may be, once delivered shall be irrevocable and may not be withdrawn unless the Issuer consents in writing to such withdrawal.

| (iii) | Stamp Duty etc.: the Issuer must pay directly to the relevant authorities any taxes and/or capital, stamp, issue and registration and transfer taxes and duties arising from a Bondholder effecting the Conversion Upon QIPO or exercising Conversion Rights (including without limitation any Duties payable in Cayman Islands, British Virgin Islands, Hong Kong and the United States and, if relevant, in the place of the Alternative Stock Exchange, in respect of the allotment and issue of Shares and listing of the Shares on the Relevant Stock Exchange on conversion)(collectively the “Taxes”). The Issuer will also pay all other expenses arising on the issue of Shares on conversion of Bonds and all charges of the share transfer agent for the Shares. The Bondholder (and, if different, the person to whom the Shares are to be issued) must declare in the relevant Conversion Notice or Certification that any amounts payable to the relevant tax authorities in settlement of any Taxes payable pursuant to this Condition 7(c)(iii) have been, or (where permitted by law) will be, paid.

1-15

If the Issuer shall fail to pay any Taxes, the relevant holder shall be entitled to tender and pay the same and the Issuer as a separate and independent stipulation, covenants to reimburse and indemnify each Bondholder in respect of any payment thereof and any penalties payable in respect thereof.

The Bondholder shall pay all, if any, taxes imposed and arising by reference to any disposal or deemed disposal of a Bond or interest therein otherwise than in connection with the exercise of Conversion Rights by any Bondholder.

| (iv) | Registration: Upon (A) Conversion Upon QIPO or (B) exercise of Conversion Rights and compliance with Conditions 7(c)(i) and 7(c)(iii) the Issuer (Y) will, as soon as practicable, and in any event not later than seven Business Days after the Conversion Date, register the person or persons designated for the purpose in the Conversion Notice or Certification (as the case may be) as holder(s) of the relevant number of Shares in the Issuer’s share register and (Z) will, within ten Business Days after the Conversion Date, if the Bondholder has also requested in the Conversion Notice or Certification (as the case may be) and to the extent permitted under applicable law and the rules and procedures of the Nasdaq Clearing AB (the “NASDAQ Clearing”) or the equivalent clearing system of an Alternative Stock Exchange effective from time to time, take all necessary action to procure that Shares are delivered through NASDAQ Clearing or the equivalent clearing system of an Alternative Stock Exchange for so long as the Shares are listed on the NASDAQ or an Alternate Stock Exchange; or will make such certificate or certificates available for collection at the office of the Issuer’s share registrar in the United States or, as the case may be, the relevant jurisdiction of the Alternate Stock Exchange notified to Bondholders in accordance with Condition 13 or, if so requested in the relevant Conversion Notice or Certification (as the case may be), will cause its share registrar to mail such certificate or certificates to the person and at the place specified in the Conversion Notice or Certification (as the case may be), together (in either case) with any other securities, property or cash required to be delivered upon conversion and such assignments and other documents (if any) as may be required by law to effect the transfer thereof, in which case a single share certificate will be issued in respect of all Shares issued on conversion of Bonds subject to the same Conversion Notice or Certification (as the case may be) and which are to be registered in the same name.

The delivery of the Shares to the converting Bondholder (or such person or persons designated in the relevant Conversion Notice or Certification (as the case may be)) in the manner contemplated above in this Condition 7(c)(iv) will be deemed to satisfy the Issuer’s obligation to pay the principal, interest and premium (if any) on such converted Bonds.

If the Conversion Date in relation to the conversion of any Bond shall be after the record date for any issue, distribution, grant, offer or other event as gives rise to the adjustment of the Conversion Price pursuant to Condition 7(d), but before the relevant adjustment becomes effective (the “Relevant Effective Date”) under the relevant Condition (a “Retroactive Adjustment”), upon the relevant adjustment becoming effective the Issuer shall procure the issue to the converting Bondholder (or in accordance with the instructions contained in the Conversion Notice or Certification (as the case may be)(subject to applicable exchange control or other laws or other regulations)), such additional number of Shares (“Additional Shares”) as is, together with Shares to be issued on conversion of the Bond(s), equal to the number of Shares which would have been required to be issued on conversion of such Bond if the relevant adjustment to the Conversion Price had been made and become effective on or immediately after the relevant record date and in such event and in respect of such Additional Shares references in this Condition 7(c)(iv) to the Conversion Date shall be deemed to refer to the Relevant Effective Date (notwithstanding that the Relevant Effective Date falls after the end of the Conversion Period).

1-16

The person or persons specified for that purpose in the Conversion Notice or Certification (as the case may be) will become the holder of record of the number of Shares issuable upon conversion with effect from the date he is or they are registered as such in the Issuer’s register of members (the “Registration Date”).

The Shares issued upon Conversion Upon QIPO or upon exercise of Conversion Rights will be fully paid and will in all respects rank pari passu with the fully paid Shares in issue on the relevant Registration Date except for any right excluded by mandatory provisions of applicable law and except that such Shares will not rank for (or, as the case may be, the relevant holder shall not be entitled to receive) any rights, distributions or payments the record or other due date for the establishment of entitlement for which falls prior to the relevant Registration Date.

If the record date for the payment of any dividend or other distribution in respect of the Shares is on or after the Conversion Date in respect of any Bond, but before the Registration Date (disregarding any Retroactive Adjustment of the Conversion Price referred to in this Condition 7(c)(iv) prior to the time such Retroactive Adjustment shall have become effective), the Issuer will calculate and pay to the converting Bondholder or such Bondholder’s designee an amount in U.S. dollars (the “Equivalent Amount”) equal to the Fair Market Value (as defined below) of such dividend or other distribution to which he would have been entitled had he on that record date been such a shareholder of record and will make the payment at the same time as it makes payment of the dividend or other distribution, or as soon as practicable thereafter, but, in any event, not later than seven days thereafter. The Equivalent Amount shall be paid by transfer to a U.S. dollar account maintained by the payee with, a bank in Hong Kong, in accordance with instructions given by the relevant Bondholder in the Conversion Notice or Certification (as the case may be).

(d) | Adjustments to Conversion Price

The Conversion Price will be subject to adjustment as follows:

| (i) | Consolidation, Subdivision or Re-classification: If and whenever there shall be an alteration to the nominal value of the Shares as a result of consolidation, subdivision or re-classification, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such alteration by the following fraction:

A

B

Where:

| A | is the nominal amount of one Share immediately after such alteration; and

| B | is the nominal amount of one Share immediately before such alteration.

Such adjustment shall become effective on the date the alteration takes effect.

1-17

(e) | Capitalisation of Profits or Reserves:

| (i) | If and whenever the Issuer shall issue any Shares credited as fully paid to the holders of Shares (“Shareholders”) by way of capitalisation of profits or reserves including, Shares paid up out of distributable profits or reserves and/or share premium account (except any Scrip Dividend) and which would not have constituted a Capital Distribution, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue by the following fraction:

A

B

Where:

| A | is the aggregate nominal amount of the issued Shares immediately before such issue; and

| B | is the aggregate nominal amount of the issued Shares immediately after such issue.

Such adjustment shall become effective on the date of issue of such Shares or if a record date is fixed therefor, immediately after such record date.

| (ii) | In the case of an issue of Shares by way of a Scrip Dividend where the Current Market Price on the date of announcement of the terms of such issue of Shares multiplied by the number of Shares issued exceeds the amount of the Relevant Cash Dividend or the relevant part thereof and which would not have constituted a Capital Distribution, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before the issue of such Shares by the following fraction:

A + B

A + C

Where:

| A | is the aggregate nominal amount of the issued Shares immediately before such issue;

| B | is the aggregate nominal amount of Shares issued by way of such Scrip Dividend multiplied by a fraction of which (i) the numerator is the amount of the whole, or the relevant part, of the Relevant Cash Dividend and (ii) the denominator is such Current Market Price of the Shares issued by way of Scrip Dividend in respect of each existing Share in lieu of the whole, or the relevant part, of the Relevant Cash Dividend; and

| C | is the aggregate nominal amount of Shares issued by way of such Scrip Dividend; or by making such other adjustment as an Independent Investment Bank and/or Independent Firm of Auditors deem fair and reasonable.

Such adjustment shall become effective on the date of issue of such Shares or if a record date is fixed therefor, immediately after such record date.

| (iii) | Capital Distributions: If and whenever the Issuer shall pay or make any Capital Distribution to the Shareholders (except to the extent that the Conversion Price falls to be adjusted under Condition 7(e) above), the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such Capital Distribution by the following fraction:

A − B

A

Where:

| A | is the Current Market Price of one Share on the date on which the Capital Distribution is publicly announced; and

1-18

| B | is the Fair Market Value on the date of such announcement of the portion of the Capital Distribution attributable to one Share.

Such adjustment shall become effective on the date that such Capital Distribution is actually made or if a record date is fixed therefor, immediately after such record date.

In making any calculation pursuant to this Condition 7(e)(iii), such adjustments (if any) shall be made as an Independent Investment Bank and/or Independent Firm of Auditors may consider appropriate to reflect (a) any consolidation or subdivision of the Shares, (b) issues of Shares by way of capitalisation of profits or reserves, or any like or similar event, (c) the modification of any rights to dividends of Shares or (d) any change in the fiscal year of the Issuer.

| (iv) | Rights Issues of Shares or Options over Shares: If and whenever the Issuer shall issue Shares to all or substantially all Shareholders as a class by way of rights, or issue or grant to all or substantially all Shareholders as a class by way of rights, options, warrants or other rights to subscribe for, purchase or otherwise acquire any Shares, in each case at less than 95 per cent. of the Current Market Price per Share on the date of the announcement of the terms of the issue or grant, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue or grant by the following fraction:

A + B

A + C

Where:

| A | is the number of Shares in issue immediately before such announcement;

| B | is the number of Shares which the aggregate amount (if any) payable for the Shares issued by way of rights or for the options or warrants or other rights issued or granted by way of rights and for the total number of Shares comprised therein would subscribe for, purchase or otherwise acquire at such Current Market Price per Share; and

| C | is the aggregate number of Shares issued or, as the case may be, comprised in the issue or grant.

Such adjustment shall become effective on the date of issue of such Shares or issue or grant of such options, warrants or other rights (as the case may be) or where a record date is set, the first date on which the Shares are traded ex-rights, ex-options or ex-warrants, as the case may be.

| (v) | Rights Issues of Other Securities: If and whenever the Issuer shall issue any securities (other than Shares or options, warrants or other rights to subscribe for, purchase or otherwise acquire Shares) to all or substantially all Shareholders as a class by way of rights, or issue or grant to all or substantially all Shareholders as a class by way of rights, options, warrants or other rights to subscribe for, purchase or otherwise acquire any securities (other than Shares or options, warrants or other rights to subscribe for, purchase or otherwise acquire Shares), the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue or grant by the following fraction:

A − B

A

Where:

| A | is the Current Market Price of one Share on the date on which such issue or grant is publicly announced; and

1-19

| B | is the Fair Market Value on the date of such announcement of the portion of the rights attributable to one Share.

Such adjustment shall become effective on the date of issue of the securities or the issue or grant of such rights, options or warrants (as the case may be) or where a record date is set, the first date on which the Shares are traded ex-rights, ex-options or ex-warrants, as the case may be.

| (vi) | Issues at less than Current Market Price: If and whenever the Issuer shall issue (otherwise than as mentioned in Condition 7(e)(iv) above or in connection with any Post-IPO Secondary Offering or Permitted Offering that otherwise complies with these Conditions) any Shares (other than Shares issued on the exercise of Conversion Rights or on the exercise of any other rights of conversion into, or exchange or subscription for, Shares) or issue or grant (otherwise than as mentioned in Condition 7(e)(iv) above) options, warrants or other rights to subscribe for, purchase or otherwise acquire Shares in each case at a price per Share which is less than 95 per cent. of the Current Market Price on the date of announcement of the terms of such issue, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue by the following fraction:

A + B

C

Where:

| A | is the number of Shares in issue immediately before the issue of such additional Shares or the grant of such options, warrants or other rights to subscribe for, purchase or otherwise acquire any Shares;

| B | is the number of Shares which the aggregate consideration (if any) receivable for the issue of such additional Shares would purchase at such Current Market Price per Share; and

| C | is the number of Shares in issue immediately after the issue of such additional Shares.

References to additional Shares in the above formula shall, in the case of an issue by the Issuer of options, warrants or other rights to subscribe or purchase Shares, mean such Shares to be issued assuming that such options, warrants or other rights are exercised in full at the initial exercise price on the date of issue or grant of such options, warrants or other rights.

Such adjustment shall become effective on the date of issue of such additional Shares or, as the case may be, the issue or grant of such options, warrants or other rights.

| (vii) | Other Issues at less than Current Market Price: Save in the case of an issue of securities arising from a conversion or exchange of other securities in accordance with the terms applicable to such securities themselves falling within this Condition 7(e)(vii), if and whenever the Issuer or any of its Subsidiaries (otherwise than as mentioned in Condition 7(e)(iv), Condition 7(e)(v) or Condition 7(e)(vi)), or (at the direction or request of or pursuant to any arrangements with the Issuer or any of its Subsidiaries) any other company, person or entity shall issue any securities (other than the Bonds, which shall be deemed to exclude any further bonds issued pursuant to Condition 16) which by their terms of issue carry rights of conversion into, or exchange or subscription for, Shares to be issued by the Issuer upon conversion, exchange or subscription at a consideration per Share which is less than 95 per cent. of the Current Market Price on the date of announcement of the terms of issue of such securities, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue by the following fraction:

A + B

A + C

1-20

Where:

| A | is the number of Shares in issue immediately before such issue;

| B | is the number of Shares which the aggregate consideration receivable by the Issuer for the Shares to be issued on conversion or exchange or on exercise of the right of subscription attached to such securities would purchase at such Current Market Price per Share; and

| C | is the maximum number of Shares to be issued on conversion or exchange of such securities or on the exercise of such rights of subscription attached thereto at the initial conversion, exchange or subscription price or rate.

Such adjustment shall become effective on the date of issue of such securities.

| (viii) | Modification of Rights of Conversion etc.: If and whenever there shall be any modification of the rights of conversion, exchange or subscription attaching to any such securities as are mentioned in Condition 7(e)(vii) (other than in accordance with the terms of such securities) so that the consideration per Share (for the number of Shares available on conversion, exchange or subscription following the modification) is reduced and is less than 95 per cent. of the Current Market Price on the date of announcement of the proposals for such modification, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such modification by the following fraction:

A + B

A + C

Where:

| A | is the number of Shares in issue immediately before such modification;

| B | is the number of Shares which the aggregate consideration receivable by the Issuer for the Shares to be issued on conversion or exchange or on exercise of the right of subscription attached to the securities so modified would purchase at such Current Market Price per Share or, if lower, the existing conversion, exchange or subscription price of such securities; and

| C | is the maximum number of Shares to be issued on conversion or exchange of such securities or on the exercise of such rights of subscription attached thereto at the modified conversion, exchange or subscription price or rate but giving credit in such manner as an Independent Investment Bank and/or Independent Firm of Auditors considers appropriate (if at all) for any previous adjustment under this Condition 7(e)(viii) or Condition 7(e)(vii).

Such adjustment shall become effective on the date of modification of the rights of conversion, exchange or subscription attaching to such securities.

1-21

| (ix) | Other Offers to Shareholders: Other than the Permitted Offerings and Post-IPO Secondary Offerings that otherwise comply with these Conditions, if and whenever the Issuer or any of its Subsidiaries or (at the direction or request of or pursuant to any arrangements with the Issuer or any of its Subsidiaries) any other company, person or entity issues, sells or distributes any securities in connection with an offer pursuant to which the Shareholders generally are entitled to participate in arrangements whereby such securities may be acquired by them (except where the Conversion Price falls to be adjusted under Condition 7(e)(iv), Condition 7(e)(v), Condition 7(e)(vi) or Condition 7(e)(vii)), the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue by the following fraction:

| B | is the Fair Market Value on the date of such announcement of the portion of the rights attributable to one Share.

Such adjustment shall become effective on the date of issue, sale or delivery of the securities.

| (x) | Cash Dividends: If and whenever the Issuer shall pay or make any Cash Dividend to the Shareholders, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such Cash Dividend by the following fraction:
