(b) The Company shall procure that EDC Holding will grant the security pursuant to the Share Charge.

(b) In the event that the Bondholder has redeemed or converted part or whole of the principal amount of the Bond, the Bondholder shall be entitled, other than in the event of any redemption pursuant to Condition 11, to interest in addition to the interest in Condition 4 (a) (the “Accrued Interest”):

(i) in respect of such part or whole of the principal amount redeemed at a simple rate of five per cent (5%) per annum calculated daily on a 180/360 day basis, payable in cash on the Maturity Date;

(ii) in respect of such part or whole of the principal amount converted at a simple rate of five per cent (5%) per annum calculated daily on a 180/360 day basis, payable on the Conversion Date in kind by the issuance of ordinary shares of the Company at the Conversion Price.

(b) If the due date for payment of any amount in respect of the Bond is not a Business Day, the Bondholder will be entitled to payment on the next following Business Day in the same manner and will not be entitled to any further interest or other payment in respect of any such delay.

6. Conversion and Redemption

(a) (i) Conversion: Subject as hereinafter provided, the Bondholder will, if the Company completes a QIPO, at any time between the date of completion of such QIPO (the “QIPO Completion Date”) and the Maturity Date (the “Conversion Period”), have the right to convert up to 100% of the principal amount of the Bond (in multiples of US$10,000,000), together with the Accrued Interest thereon, into ordinary shares of the Company, by giving a Conversion Notice (as defined below) to the Company requiring the Company to convert the Bond in whole or in part. The Conversion Price shall be US$1.675262 subject to adjustment as hereafter described. No fraction of an ordinary share will be issued on conversion and the number or ordinary shares issued will be rounded down to the nearest whole number, but an equivalent cash payment in United States dollars will be made to the Bondholder in respect of such fraction.

(ii) Company’s call: If the Company completes a QIPO and the closing price of its Shares is at or above 125% of the Conversion Price (i.e. 25% premium to the Conversion Price) for a period of at least ten (10) consecutive trading days, the Company may, at its unilateral option, give two (2) month’s notice to the Bondholder that the Bond then outstanding will be mandatorily converted at the end of the notice period in accordance with this Terms and Conditions of the Bond.

(iii) Lock-up: Any Shares issued as a result of conversion of the Bond during the one (1) year period following the QIPO Completion Date shall be locked up until the 1-year anniversary of the QIPO Completion Date. Such lock-up will not apply to the existing Shareholders of the Company.

(iv) Pre-emptive rights: For one (1) year following the First Tranche Issue Date, the Bondholder shall be entitled to participate proportionately in any issuance by the Company of convertible bonds at the same interest rate and on the same terms and conditions as the Company offers to other investors. The proportionate entitlement of the Bondholder will be calculated as if all convertible capital, options, warrants, etc. issued and outstanding on the date of the proposed issue are converted. For the avoidance of doubt, the pre-emptive rights shall not apply to the Second Tranche, Third Tranche (if any) and Fourth Tranche (if any) of the Bond.

(v) Redemption on maturity: Unless previously converted or purchased and cancelled in the circumstances referred to herein and subject to Condition 1(b), the Bond will be redeemed on the fourth (4th) anniversary from the First Tranche Issue Date at its principal amount, plus Accrued Interest thereon.

(b) Conversion Notice:

(i) To exercise the Conversion Rights attaching to any Bond, the Bondholder must complete, execute and deposit at his own expense during 9 a.m. to 5 p.m., on any Business Day at the principal place of business of the Company a written notice of conversion as set out in Exhibit B hereto (the “Conversion Notice”) in duplicate, together with the relevant Certificate and any amounts required to be paid by the Bondholder under Condition 6(c).

(ii) The conversion date in respect of the Bond (the “Conversion Date”) must fall at a time when the Conversion Rights attaching to the Bond is expressed in these Terms and Conditions to be exercisable and will be deemed to be the Business Day immediately following the date of the surrender of the Certificate in respect of such Bond and delivery of such Conversion Notice and, if applicable, any payment to be made or indemnity given under these Terms and Conditions in connection with the exercise of such Conversion Rights.

(iii) A Conversion Notice once delivered shall be irrevocable and may not be withdrawn unless the Company consents to such withdrawal.

(c) Stamp duty and taxes: The Company shall pay to the relevant tax authorities any taxes and stamp, issue and registration duties arising on conversion, if any, and a Bondholder delivering a certificate in respect of a Bond for conversion must pay all, if any, taxes arising by reference to any disposal or deemed disposal of the Bond in connection with such conversion. The Company is under no obligation to determine whether the Bondholder is liable to pay any taxes or the amounts thereof payable (if any) in connection with this Condition 6(c).

(d) Cancellation: All Bonds, which are redeemed or converted or purchased by the Company, will forthwith be cancelled. Certificates in respect of all Bonds cancelled will be forwarded to the Company and such Bonds may not be re-issued or sold.

7. Adjustments

(a) Subject hereinafter provided, the Conversion Price shall from time to time be adjusted in accordance with the following relevant provisions and so that if the event giving rise to any such adjustment shall be such as would be capable of falling within more than one of sub-paragraphs (i) to (vii) inclusive of this Condition 7(a) it shall fall within the first of the applicable paragraphs to the exclusion of the remaining paragraphs :-

(i) If and whenever the Shares by reason of any consolidation or sub-division become of a different nominal amount, the Conversion Price in force immediately prior thereto shall be adjusted by multiplying it by the revised nominal amount and dividing the result by the former nominal amount. Each such adjustment shall be effective from the close of business in Hong Kong on the day immediately preceding the date on which the consolidation or sub-division becomes effective.

(ii) If and whenever the Company shall issue (other than in lieu of a cash dividend) any Shares credited as fully paid by way of capitalization of profits or reserves (including any share premium account or capital redemption reserve fund), the Conversion price in force immediately prior to such issue shall be adjusted by multiplying it by the aggregate nominal amount of the issued Shares immediately before such issue and dividing the result by the sum of such aggregate nominal amount and the aggregate nominal amount of the Shares issued in such capitalization. Each such adjustment shall be effective (if appropriate retroactively) from the commencement of the day next following the record date for such

issue.

(iii) If and whenever the Company shall make any Capital Distribution (as defined in Condition 7(b)) to holders (in their capacity as such) of Shares (whether on a reduction of capital or otherwise) or shall grant to such holders rights to acquire for cash assets of the Company or any of its Subsidiaries, the Conversion Price in force immediately prior to such distribution or grant shall be adjusted by multiplying it by the following fraction.

A-B

Where :-

A = the market price on the date on which the Capital Distribution, or, as the case may be, the grant is announced or (failing any such announcement) next preceding the date of the Capital Distribution or, as the case may be, of the grant; and

B = the fair market value on the day of such announcement or (as the case may require) the next preceding day, as determined in good faith by an approved merchant bank, of the portion of the Capital Distribution or of such rights which is attributable to one Share,

Provided that :-

(aa) if in the opinion of the relevant approved merchant bank, the use of the fair market value as aforesaid produces a result which is significantly inequitable, it may instead determine (and in such event the above formula shall be construed as if B meant) the amount of the said market price which should properly be attributed to the value of the Capital Distribution or rights; and

(bb) the provisions of this sub-paragraph (iii) shall not apply in relation to the issue of Shares paid out of profits or reserves and issued in lieu of a cash dividend.

Each such adjustment shall be effective (if appropriate retroactively) from the commencement of the day next following the record date for the Capital Distribution or grant.

(iv) if and whenever the Company shall offer to holders of Shares new Shares for subscription by way of rights, or shall grant to holders

of Shares any options or warrants to subscribe for new shares, at a price which is less than eighty per cent (80%) of the market price at the date of the announcement of the terms of the offer or grant, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before the date of such announcement by a fraction of which the numerator is the number of shares in issue immediately before the date of such announcement plus the number of Shares which the aggregate of the amount (if any) payable for the rights, options or warrants and of the amount payable for the total number of new Shares comprised therein would purchase at such market price and the denominator is the number of Shares in issue immediately before the date of such announcement plus the aggregate number of Shares offered for subscription or comprised in the options or warrants (such adjustment to become effective (if appropriate retroactively) from the commencement of the day next following the record date for the offer or grant).

(v) (aa) Subject to Condition 7(c), if and whenever the Company shall issue wholly for cash any securities which by their terms are convertible into or exchangeable for or carry rights of subscription for new Shares, and the total Effective Consideration per Share (as defined below) initially receivable for such securities is less than eighty per cent (80%) of the market price at the date of the announcement of the terms of issue of such securities, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately prior to the issue by a fraction of which the numerator is the number of Shares in issue immediately before the date of the issue plus the number of Shares which the total Effective Consideration receivable for the securities issued would purchase at such market price and the denominator is the number of Shares in issue immediately before the date of the issue plus the number of Shares to be issued upon conversion or exchange of, or the exercise of the subscription rights conferred by, such securities at the initial conversion or exchange rate or subscription price. Such adjustment shall become effective (if appropriate retrospectively) from the close of business in Hong Kong on the Business Day next preceding whichever is the earlier of the date on which the issue is announced and the date on which the Company determines the conversion or exchange rate or

subscription price.

(bb) Subject to Condition 7(c), if and whenever the rights of conversion or exchange or subscription attached to any such securities as are mentioned in section (aa) of this sub-paragraph (v) are modified so that the total Effective Consideration per Share initially receivable for such securities shall be less than eighty per cent (80%) of the market price at the date of announcement of the proposal to modify such rights of conversion or exchange or subscription, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately prior to such modification by a fraction of which the numerator is the number of Shares in issue immediately before the date of such modification plus the number of Shares which the total Effective Consideration receivable for the securities issued at the modified conversion or exchange price would purchase at such market price and of which the denominator is the number of Shares in issue immediately before such date of modification plus the number of Shares to be issued upon conversion or exchange of or the exercise of the subscription rights conferred by such securities at the modified conversion or exchange rate or subscription price. Such adjustment shall become effective as at the date upon which such modification shall take effect. A right of conversion or exchange or subscription shall not be treated as modified for the foregoing purposes where it is adjusted to take account of rights or capitalization issues and other events normally giving rise to adjustment of conversion or exchange terms.

For the purposes of this sub-paragraph (v), the “total Effective Consideration” receivable for the securities issued shall be deemed to be the consideration receivable by the Company for any such securities plus the additional minimum consideration (if any) to be received by the Company upon (and assuming) the conversion or exchange thereof or the exercise of such subscription rights, and the total Effective Consideration per Share initially receivable for such securities shall be such aggregate consideration divided by the number of Shares to be issued upon (and assuming) such conversion or exchange at the initial conversion or exchange rate or the exercise of such subscription rights at the initial

subscription price, in each cases without any deduction for any commissions, discounts or expenses paid, allowed or incurred in connection with the issue.

(vi) Subject to Condition 7(c), if and whenever the Company shall issue wholly for cash any Shares at a price per Share which is less than eighty per cent (80%) of the market price at the date of the announcement of the terms of such issue, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before the date of such announcement by a fraction of which the numerator is the number of Shares in issue immediately before the date of such announcement plus the number of Shares which the aggregate amount payable for the issue would purchase at such market price and the denominator is the number of Shares in issue immediately before the date of such announcement plus the number of Shares so issued. Such adjustment shall become effective on the date of the issue.

(vii) Subject to Condition 7(c), if and whenever the Company shall issue Shares for the acquisition of asset at a total Effective Consideration per Share (as defined below) which is less than eighty per cent (80%) of the market price at the date of the announcement of the terms of such issue, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before the date of such announcement by a fraction of which the numerator is the number of Shares in issue immediately before the date of such announcement plus the number of Shares which the total Effective Consideration would purchase at such market price and the denominator is the number of Shares in issue immediately before the date of such announcement plus the number of Shares so issued. Each such adjustment shall be effective (if appropriate retroactively) from the close of business in Hong Kong on the business day immediately preceding whichever is the earlier of the date on which the issue is announced and the date on which the Company determines the issue price for such Shares. For the purpose of this subparagraph (vii) “total Effective Consideration” shall be the aggregate consideration credited as being paid for such Shares by the Company on acquisition of the relevant asset without any deduction of any commissions, discounts or expenses paid, allowed or incurred in connection with the issue thereof, and the “total Effective Consideration per Share” shall be the total Effective Consideration divided by the number of Shares issued as aforesaid.

(b) For the purposes of this Condition 7

“approved merchant bank” means a merchant bank of repute in Hong Kong jointly selected by the Company and the Investors in good faith for the purpose of providing a specific opinion or calculation or determination hereunder, or if there is no agreement among the Company and the Investors, to be selected by the Chairperson of the Hong Kong International Arbitration Centre;

“Shares” includes, for the purposes of Shares comprised in any issue, distribution on grant pursuant to sub-paragraphs (iii), (iv), (v), (vi) or (vii) of Condition 7(a), any such ordinary shares of the Company as, when fully paid, will be Shares.
