	3.1	The Global Certificates: On issue of each tranche of the Bonds, a Global Certificate will be issued in respect of the aggregate principal amount of that tranche of the Bonds and the
Issuer shall procure the Registrar to make such entries of each tranche of the Bonds in the Register as appropriate. Each Global Certificate will be issued and registered in the name of a nominee of, and deposited with, a common depositary for
Euroclear and Clearstream, Luxembourg. A Global Certificate need not be security printed. Each tranche of the Bonds evidenced by a Global Certificate shall be subject to its terms in all respects and entitled to the same benefits under this Trust
Deed as Bonds of the relevant tranche evidenced by individual definitive Certificates. 

  

	3.2	The definitive Certificates: The definitive Certificates, if issued, will be security printed in accordance with all applicable legal and stock exchange requirements and will be
substantially in the form set out in the applicable part of Schedule 1 and endorsed with the relevant Conditions. 

  

	3.3	Signature: Each Global Certificate (and the definitive Certificates, if issued) will be signed manually or in facsimile by one or more directors or officers of the Issuer duly
authorised by the Issuer for the purpose, or manually or in facsimile by any duly authorised attorney of the Issuer, and authenticated manually by or on behalf of the Registrar, upon receipt of a written order from the Issuer. The Issuer may use the
signature of any person who as at the date of this Trust Deed is an authorised officer or attorney, as the case maybe, of the Issuer even if at the time of issue of any definitive Certificate or the Global Certificate he no longer holds such office
and the Bonds in respect of which the Global Certificate or a definitive Certificate is so executed and authenticated will be valid evidence of binding obligations of the Issuer. 

  

	3.4	Issue: Issue and delivery of each tranche of the Bonds shall be completed on the issue and delivery of the relevant Global Certificate to the common depositary referred to in Clause
3.1 (or its representative) by, or by the order of, the Issuer and completion of the Register by or on behalf of the Registrar. 

  

	3.5	Entitlement to treat holder as owner: The registered holder of any Bond will (save as otherwise required by law) be treated as its absolute owner for all purposes (whether or not it
is overdue and regardless of any notice of ownership, trust or any interest in it or any writing on or the theft or loss of the Certificate issued in respect of it) and no person will be liable for so treating the holder. 

 

	3.6	 Authentication: No Certificate shall be entitled to any benefit under this Trust Deed or be valid for any purpose, unless and until authenticated by the manual
signature of the Registrar. The Registrar’s authentication to be borne on the Certificates shall 

  

 9 

	 	 
be the certificate of authentication substantially as set out in the form of Schedule 2, and such certificate upon any Bond shall be conclusive evidence, and
the only evidence, that such Certificate has been duly authenticated and delivered thereunder. 

  

	4.	STAMP DUTIES AND TAXES 

 The Issuer will pay any
stamp, issue, registration, documentary, transfer or other taxes and duties, including interest and penalties, payable in respect of the creation, issue and offering of the Bonds, the execution or delivery of this Trust Deed and the deposit of
Certificates for the conversion of Bonds and the issue and delivery of Shares following such deposit. The Issuer will also indemnify the Trustee and the Bondholders from and against all stamp, issue, registration, documentary or other taxes and
duties paid by any of them in any jurisdiction in connection with any action taken by or on behalf of the Trustee or, as the case may be, (where entitled under Condition 14 to do so) the Bondholders to enforce the obligations of the Issuer under
this Trust Deed or the Bonds, or to resolve any doubt concerning, or for any other purpose in relation to this Trust Deed. 
  

	5.	COVENANT OF COMPLIANCE 

  

	5.1	The Issuer covenants with the Trustee and the Security Agent that it will comply with and perform and observe all the provisions of these presents which are expressed to be binding
on it. The Conditions shall be binding on the Issuer, the Trustee, the Security Agent and the Bondholders. The Trustee and the Security Agent shall be entitled to enforce the obligations of the Issuer under the Bonds as if the same were set out and
contained in the trust deeds constituting the same, which shall be read and construed as one document with the Bonds. The Trustee will hold the benefit of this covenant upon trust for itself and the Bondholders according to its and their respective
interests. 

  

	5.2	The Issuer represents and warrants to the Trustee on the terms of Condition 5, as if the same were set out in full in this Deed. 

  

	6.	COVENANTS RELATING TO THE CONVERSION RIGHT 

 So long
as any Bond remains outstanding, save with the approval of an Extraordinary Resolution of the Bondholders, the Issuer will: 
  

	6.1	Availability of Shares: keep available, free from pre-emptive or other rights, out of its authorised but unissued Shares such number of Shares as would be required to be issued on
conversion of all the Tranche B Bonds from time to time remaining outstanding and to satisfy in full all other rights of conversion into or exchange or subscription for Shares and shall ensure that all Shares delivered on conversion of the Tranche B
Bonds will be duly and validly issued as fully-paid and non-assessable; 

  

	6.2	Limited Modification of Rights: not modify the rights attaching to the Shares with respect to voting, dividends or liquidation nor issue any other class of share capital carrying
any rights which are more favourable than the rights attaching to Shares; 

  

	6.3	Limited Grant of Rights: except expressly permitted under the Conditions, not grant, or permit the grant of, any options, warrants or other rights to subscribe for, or call for, or
exchange for, the allotment or issue of any Shares and procure that no securities (whether issued by the Issuer or any of its Subsidiaries) issued without rights to convert into or exchange or subscribe for Shares shall subsequently be granted such
rights and ensure that at no time shall there be in issue Shares of differing par values; 

  

	6.4	Offer: except expressly permitted under the Conditions, procure that no Shareholder, shall sell or agree to sell or grant any right in issued equity share capital of the Issuer;

  

 10 

	6.5	No Reduction of Issued Share Capital: not make any reduction of its ordinary share capital or any uncalled liability in respect thereof or of any share premium account or capital
redemption reserve fund; 

  

	6.6	Closing of Register of Members: unless so required by applicable law or regulation or in order to determine the entitlement of rights to a dividend or other rights attaching to the
Shares or entitlements of the Shareholders, not close its Register of Members or take any other action which prevents the transfer of its Shares generally and ensure that the Bonds may be converted legally and the Shares issued on conversion may
(subject to any limitation imposed by law) be transferred (as between transferor and transferee) at all times while the Register is closed or such other action is effective, nor take any action which prevents the conversion of the Bonds or the issue
of Shares in respect of them; 

  

	6.7	Listing of Shares: (i) use its best endeavours to undertake and complete a listing for all the Shares issued on exercise of the Conversion Rights attached to the Tranche B
Bonds on the Stock Exchange as a Complying IPO (as defined in Condition 8.1(b) of the Tranche B Conditions) within 12 months of the Issue Date and (ii) forthwith give notice to the Bondholders in accordance with Condition 19 of any such listing
or delisting of Shares (as a class) by the Stock Exchange; 

  

	6.8	Expenses: pay the expenses of the issue of, and all expenses of obtaining and maintaining a listing for, Shares arising on conversion of the Tranche B Bonds.

 For the above purposes, equity share capital means the share capital of a company excluding any part of that capital
which, neither as respects dividends nor as respects capital, carries any right to participate beyond a specified amount in a distribution. 
  

	7.	ENFORCEMENT 

  

	7.1	Each of the Trustee and the Security Agent may at any time, at its discretion and without notice, take such proceedings and/or other steps as it may think fit against or in relation
to the Issuer to enforce its obligations under this Trust Deed, the Security Documents and the other Finance Documents (as the case may be). The Trustee may instruct the Security Agent to take such proceedings and/or other steps as it may think fit
against or in relation to the Issuer to enforce its obligations under this Trust Deed, the Security Documents and the other Finance Documents (as the case maybe). 

  

	7.2	Proof that as regards any specified Bond the Issuer has made default in paying any amount due in respect of such Bond shall (unless the contrary be proved) be sufficient evidence
that the same default has been made as regards all other Bonds in respect of which the relevant amount is due and payable. 

  

	7.3	The Bonds are, or will be, upon execution of the Security Documents and completion of all perfection requirements, secured by the Collateral granted under the Security Documents,
each in favour of the Security Agent for the benefit of the Secured Parties. 

  

	7.4	Neither the Trustee nor the Security Agent shall be responsible or liable in any manner whatsoever with respect to: 

  

	 	(a)	any loss or theft or reduction in value of the Collateral, and shall not be obliged to insure the same, any certificate, note, Bonds or other evidence in respect thereof, or to
require any other person to maintain any such insurance; 

  

	 	(b)	the creation, perfection, legality and enforceability under applicable laws, or the sufficiency and/or maintenance of, any Security Documents, any Collateral or any agreement,
assignment or other document relating thereto; and/or 

  

 11 

	 	(c)	investigating or determining the creditworthiness of the Collateral, the Obligors or the validity of any of the obligations of any Obligor under the Security Documents or any of the
terms of the Security Documents. 

  

	7.5	At any time after any security under the Security Documents shall have become enforceable, the Security Agent if (i) it shall have been directed by an Extraordinary Resolution
of the Bondholders and (ii) it shall have been indemnified and/or secured to its satisfaction shall, and otherwise in its sole discretion may, enforce the security under the Security Documents. To enforce the security under the Security
Documents, it may, following the security under the Security Documents becoming enforceable, at its discretion, take possession of all or part of the Collateral and may in its discretion sell, call in, collect and convert into money, all or part of
the Collateral in such manner and on such terms as it shall think fit or do any of the following things subject to applicable law: 

  

	 	(a)	manage and carry on the business and affairs of the Issuer or AST (HK) with respect to the Collateral or any part thereof as it thinks fit with power to appoint or dismiss managers,
agents and employees; 

  

	 	(b)	insure and protect the Collateral or any part thereof; 

  

	 	(c)	settle, adjust, refer to arbitration, compromise or arrange all accounts, questions, disputes, claims and demands whatsoever in relation to the Collateral or any part thereof;

  

	 	(d)	execute and do contracts, deeds, documents and things and bring, defend or abandon actions, suits and proceedings in relation to the Collateral or any part thereof in the name of
the Issuer or AST (HK); 

  

	 	(e)	exercise or permit any other person to exercise any powers or rights incidental to the ownership of the Collateral or any part thereof; 

  

	 	(f)	discharge the Collateral or any part thereof from any charge securing the Secured Liabilities (as defined in each Security Document) or release the Issuer or AST (HK) from any
obligation where the Security Agent considers such release or discharge to be expedient and in the interests of the Secured Parties and on such terms and conditions as it thinks fit; and 

  

	 	(g)	generally to do anything in relation to the Collateral or any part thereof as it could do if it were the absolute beneficial owner of the Collateral. 

  

	7.6	The Security Agent may in writing appoint a receiver or such other analogous entity under the applicable laws (the Receiver) of all or part of the Collateral and may remove
any Receiver so appointed and appoint another in his place. No delay or waiver of the right to exercise these powers shall prejudice their future exercise. The following provisions subject to applicable laws shall have effect:

  

	 	(a)	such appointment may be made before or after the Security Agent shall have taken possession of all or part of the relevant Collateral; 

  

	 	(b)	such Receiver may be vested by the Security Agent with such powers and discretions as the Security Agent may think expedient and may sell, concur in selling, assign or release any
of the Collateral without restriction and on such terms as he may think fit, and may effect any such transaction in the name or on behalf of the Issuer or AST (HK) or otherwise; 

  

	 	(c)	the Security Agent may from time to time fix such Receiver’s remuneration and direct its payment out of moneys accruing to it in the exercise of its powers as such Receiver.
Nothing contained in this Trust Deed shall render either of the Trustee or the Security Agent or Bondholders liable to any such Receiver for its remuneration or any other costs and expenses; 

  

 12 

	 	(d)	the Security Agent may from time to time and at any time require such Receiver to give security for the due performance of his duties as Receiver, and may fix the nature and amount
of the security to be given. The Security Agent need not, however, in any case require any such security nor shall it be responsible for its adequacy or sufficiency, 

  

	 	(e)	all moneys received by such Receiver shall be paid over to the Security Agent unless the Security Agent directs otherwise; and 

  

	 	(f)	such Receiver shall be the Issuer’s agent for all purposes. The Issuer alone shall be responsible for its acts, omission, defaults and misconduct, and none of the Trustee, the
Security Agent or the Bondholders shall incur any Liability or responsibility therefor provided however that the Receiver shall be liable to the Issuer for any loss or damage due to the Receiver’s fraud, wilful default or gross negligence.

  

	7.7	The Issuer shall take such action and procure that the other Obligor take such action as the Security Agent may reasonably require (a) to perfect or protect the security
created or intended to be created by or pursuant to this Trust Deed and the Security Documents and (b) at any time after the security constituted by or pursuant to this Trust Deed and the Security Documents shall have become enforceable, to
facilitate the realisation of such security and the exercise of the functions of the Security Agent or any Receiver of any such security. The Security Agent accepts no responsibility for the perfection or protection of the security under the
Security Documents. 

  

	7.8	Following the security under the Security Documents becoming enforceable hereunder: 

  

	 	(a)	the Security Agent may raise and borrow money on the security of the Collateral or any part of it in order to defray moneys, costs, charges, losses and expenses paid or incurred by
it in relation to this Trust Deed and the Security Documents (including the costs of realising any security and the remuneration of the Security Agent) or in exercise of its functions pursuant to this Trust Deed and the Security Documents (provided
that the Bondholders shall have no Liability for any such borrowings); and 

  

	 	(b)	the Security Agent may raise and borrow such money on such terms as it shall think fit and may secure its repayment with interest by pledging or otherwise charging all or part of
the Collateral and generally in such manner and form as the Security Agent shall think fit, and for such purposes may take such action as it shall think fit (provided that the Bondholders shall have no Liability for any such borrowings).

  

	7.9	The Issuer irrevocably appoints the Security Agent and every Receiver of the Collateral to be severally its attorney (with full power of substitution) on its behalf and in its name
to do anything following enforcement of the Collateral under the Security Documents which the Issuer ought to do under this Trust Deed or the Security Documents and generally to exercise all or any of its functions. The Issuer agrees to, and hereby
ratifies and confirms, whatever any such attorney shall do or purport to do in the exercise or purported exercise of such functions following the enforcement of security under the Security Documents. For the avoidance of doubt, this power of
attorney will only be effective upon and following the occurrence of an Event of Default. 

  

	7.10	Neither the Security Agent nor any Bondholder, nor any such Receiver or any attorney or agent of the Security Agent shall by reason of taking possession of any the Collateral or any
other reason and whether or not as pledgee or mortgagee in possession be liable to account for anything except actual receipts or be liable for any loss or damage arising from the realisation of the Collateral, or from any act, default or omission
in relation to the Collateral or otherwise, unless such loss or damage shall be caused by its own wilful misconduct, gross negligence or fraud. 

  

 13 

	7.11	No one dealing with the Security Agent or any Receiver of the Collateral need enquire whether any of the powers, authorities and discretions conferred by or pursuant to this Trust
Deed in relation to such assets are or may be exercisable by the Security Agent or such Receiver or as to the propriety or regularity of acts purporting or intended to be in the exercise of any such powers. 

  

	7.12	The security created under the Security Documents shall be discharged as soon as reasonably practicable on or after the date on which all of the obligations of the Security Parties
have been fulfilled in full in accordance with the Conditions and the terms of this Trust Deed. 

  

	8.	ACTION, PROCEEDINGS AND INDEMNIFICATION 

  

	8.1	Neither the Trustee nor the Security Agent shall be bound to take any proceeding or any other action in relation to the Finance Documents (including but not limited to the giving of
any notice pursuant to Condition 12 or the taking of any proceedings and/or other steps mentioned in Clause 7) unless respectively directed or requested to do so by an Extraordinary Resolution and then only if it shall be indemnified and/or secured
to its satisfaction against all Liabilities to which it may render itself liable or which it may incur by so doing. 

  

	8.2	Only the Trustee and/or the Security Agent may enforce the provisions of these presents and the Security Documents. No Bondholder shall be entitled to proceed directly against the
Issuer to enforce the performance of any of the provisions of these presents unless the Trustee and/or the Security Agent having become bound as aforesaid to take proceedings fails to do so within a reasonable period and such failure is continuing.

  

	9.	NOTICE OF PAYMENTS 

 The Trustee shall give notice
to the Bondholders in accordance with Condition 19 of the day fixed for any payment to them under Clause 11. Such payment may be made in accordance with Condition 9 and any payment so made shall be a good discharge to the Trustee. 
  

	10.	PARTIAL PAYMENTS 

 Upon any payment under Clause 11
(other than payment in full against surrender of a Bond) the Bond in respect of which such payment is made shall be produced to the Trustee or the Principal Agent by or through whom such payment is made and the Trustee shall or shall cause such
Principal Agent to enface thereon a memorandum of the amount and the date of payment but the Trustee may in any particular case dispense with such production and enfacement upon such indemnity being given as it shall think sufficient. 
  

	11.	APPLICATION OF MONEYS RECEIVED BY THE TRUSTEE 

  

	11.1	Declaration of Trust: All moneys received by the Trustee or the Security Agent in respect of the Bonds or amounts payable under this Trust Deed or the Security Documents (including
the proceeds of enforcement of the Collateral) will, despite any appropriation of all or part of them by the Issuer, be held by the Trustee or the Security Agent upon trust to apply them (subject to Clause 11.2): 

  

	 	(a)	first, in payment of all costs, charges, expenses and liabilities incurred by the Trustee and/or any Appointee (as defined in Clause 14.23), the Security Agent, any Receiver
appointed under the Security Documents and Agents (including remuneration payable to the Trustee and/or any Appointee, the Security Agent, any Receiver appointed under the Security Documents and Agents) in carrying out its functions under this Trust
Deed, the Security Documents and the Agency Agreement (including any taxes and other amounts required to be paid and the costs of realising any Collateral, if applicable); 

  

 14 

	 	(b)	secondly, in payment of any amounts of principal, interest, and premium (if any) owing in respect of the Bonds pari passu and rateably; 

  

	 	(c)	thirdly, in payment of any other amounts owing in respect of the Bonds; and 

  

	 	(d)	fourthly, in payment of any balance (if any) to the Issuer for itself. 

 If the Trustee holds any moneys which represent principal, interest or premium (if any) in respect of Bonds in respect of which claims have become prescribed under Condition 13, the Trustee will hold them on trust and
apply them as set out in this Clause 11.1. 
  

	11.2	Accumulation: The Trustee may at its discretion and pending payment invest moneys at any time available for the payment of principal, premium (if any) and interest on the Bonds if
the amount of such moneys is less than 10% of the principal amount of the Bonds then outstanding, in some or one of the investments hereinafter authorised for such periods as it may consider expedient with power from time to time at the like
discretion to vary such investments and to accumulate such investments and the resulting interest and other income derived therefrom. The accumulated investments shall be applied under Clause 11.1. All interest and other income deriving from such
investments shall be applied first in payment or satisfaction of all amounts then due and unpaid under Clause 13 to the Trustee and/or any Appointee and otherwise held for the benefit of and paid to the Bondholders. 

  

	11.3	Investment: Moneys held by the Trustee may be invested in its name or under its control in any investments or other assets anywhere whether or not they produce income or deposited
in its name or under its control at such bank or other financial institution in such currency as the Trustee may, in its absolute discretion, think fit. If they are deposited at a bank or institution that is the Trustee or a subsidiary, holding or
associated company of the Trustee, it needs only account for an amount of interest calculated at the rate per annum equal to the best rate payable by it on a deposit of like amount to an independent customer. The Trustee may at any time vary or
transpose any such investments or assets or convert any moneys so deposited into any other currency, and will not be responsible for any resulting loss, whether by depreciation in value, change in exchange rates or otherwise.

otherwise outside the scope of the normal duties of the Trustee under this Trust Deed, or upon such additional remuneration, such matters shall be determined by a person (acting as an expert and not as an arbitrator) selected by the Trustee and
approved by the Issuer or, failing such approval, nominated (on the application of the Trustee) by the President for the time being of The Law Society of England and Wales (the expenses involved in such nomination and the fees of such person being
payable by the Issuer) and the determination of any such person shall be final and binding upon the Trustee and the Issuer.

reimburses the Trustee or, as the case may be, the Security Agent and in all other cases shall (if not paid on the date specified in such demand and the Trustees or, as the case maybe, the Security Agent so requires) carry interest at such rate from
the date specified in such demand until payment by the Issuer to the Trustee or, as the case may be, the Security Agent. All remuneration payable to the Trustee or, as the case may be, the Security Agent shall carry interest at such rate from the
due date therefor.

Agent under this Clause shall be made without set-off, counterclaim, deduction or withholding unless compelled by law in which event the Issuer will pay such additional amounts as will result in the receipt by the Trustee or, as the case may be, the

	13.8	Survival of Clauses: Unless otherwise specifically stated in any discharge of this Trust Deed the provisions of this Clause 13 shall continue in full force and effect
notwithstanding such discharge.

execution of any of its trusts, powers, authorities and discretions under the Trust Deed, the Security Documents and/or Agency Agreement) or its or his functions under any such appointment or in respect of any other matter or thing done or omitted
in any way relating to this Trust Deed or the Security Documents or any such appointment (including all liabilities incurred in disputing or defending any of the foregoing), unless the claim for loss or damages is made in respect of fraud, gross
negligence or wilful default on the part of the Trustee or the Security Agent, as the case may be. 

  

	13.10	Reliance etc. of Documents: The Trustee or any Appointee or the Security Agent shall not be liable for any default resulting from force majeure, which shall be deemed to include any

expenses and other amounts payable to the Trustee or, as the case may be, the Security Agent. A failure by the Trustee or the Security Agent to present an invoice shall not release the Issuer from the liability in respect of such fees, expenses and
other amounts. 

  

	14.	PROVISIONS SUPPLEMENTAL TO THE TRUSTEE ACTS 

 Section 1 of the Trustee Act 2000 shall not apply to the duties of the Trustee or the Security Agent in relation to the trusts constituted by this Trust Deed. Where there are any inconsistencies between the Trustee Acts and the
provisions of this Trust Deed, the provisions of this Trust Deed shall, to the extent allowed by law, prevail and, in the case of any such inconsistency with the Trustee Act 2000, the provisions of this Trust Deed shall constitute a restriction or
exclusion for the purposes of that Act. The Trustee shall have all the powers conferred upon trustees by the Trustee Acts. In addition, both the Trustee and the Security Agent shall have the powers set out below. 
  

	14.1	Advice: Each of the Trustee and the Security Agent may act or rely on the opinion or advice of, or information or certificate or report obtained from, any lawyer, valuer, accountant
(including the Auditors), banker or other expert whether obtained by or addressed to the Issuer, the Trustee, the Security Agent, the Principal Agent or otherwise, and notwithstanding any monetary or other limit on liability contained therein, will
not be responsible to anyone for any Liability occasioned by so acting. Any such opinion, advice or information may be sent or obtained by letter, telex, fax or electronic mail and neither the Trustee nor the Security Agent will be liable to anyone
for acting or relying in good faith on any opinion, advice or information purporting to be conveyed by such means, notwithstanding any limitation on liability (monetary or otherwise) in relation to such person’s opinion or advice and even if it
contains some error or is not authentic. 

  

	14.2	 Trustee to Assume Performance: Neither the Trustee nor the Security Agent need to notify anyone of the execution of this Trust Deed or any documents referred to in
this Trust Deed or do anything to find out if an Event of Default or Potential Event of Default or IPO or Complying IPO has occurred. Until it has actual knowledge or express notice to the contrary, each of the Trustee and the Security Agent may
assume that no Event of Default or Potential Event of Default or IPO or Complying IPO has occurred and that the Issuer is performing all its obligations under this Trust Deed, the Bonds, the Security Documents and the other Finance Documents and no
event has happened as a consequence of which any of the Bonds may become repayable. Each of the Trustee and the Security Agent shall not be bound to take any steps to ascertain whether any event, condition or act, the happening of which would cause
a right or remedy to become exercisable by the Trustee or, as the case may be, the 

  

 19 

	 	 
Security Agent under the Finance Documents has happened or to monitor or supervise the observance and performance by any Obligor of their respective
obligations thereunder and, until it shall have express notice to the contrary and is indemnified and/or secured to its satisfaction, the Trustee and the Security Agent shall be entitled to assume that no such event, condition or act has happened
and the Obligors and each of the other parties thereto are observing and performing all their respective obligations thereunder. The Trustee shall not be obliged to declare the Bonds immediately due and payable unless it has been indemnified and/or
secured to its satisfaction in respect of the costs, claims and liabilities which it has incurred to that date and to which it may thereby and as a consequence thereof in its opinion render itself, or have rendered itself, liable.

  

	14.3	Resolutions of Bondholders: Neither the Trustee nor the Security Agent shall be liable to any person by reason of having acted upon any Extraordinary Resolution in writing or any
Extraordinary Resolution or other resolution purporting to have been passed at any meeting of Bondholders in respect whereof minutes have been made and signed or any direction or request of Bondholders even though subsequent to its acting it may be
found that there was some defect in the constitution of the meeting or the passing of the resolution or (in the case of an Extraordinary Resolution or other resolution in writing) that not all Bondholders had signed the Extraordinary Resolution or
other resolution or (in the case of a direction or request) it was not signed by the requisite number of Bondholders or that for any reason the resolution, direction or request was not valid or binding upon such Bondholders.

  

	14.4	Illegality/Expenditure of Trustee Funds: No provision of this Trust Deed or the Security Documents shall require the Trustee or the Security Agent to do anything which may:
(i) be illegal or contrary to applicable law or regulation; (ii) cause it to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties or in the exercise of any of its own rights or
powers, if it shall have grounds for believing that repayment of such funds or satisfactory indemnity against such risk or the liability is not assured to it. 

  

	14.5	Officers’ Certificate: If the Trustee or the Security Agent, in the exercise of its functions under this Trust Deed or the Security Documents, requires to be satisfied or to
have information as to any fact or the expediency of any act, it may call for and accept as sufficient evidence of that fact or the expediency of that act an Officers’ Certificate as to that fact or to the effect that, in their opinion, that
act is expedient and neither the Trustee nor the Security Agent need to call for further evidence and will not be responsible for any loss occasioned by acting on such a certificate. 

  

	14.6	Deposit of Documents: Each of the Trustee and the Security Agent may appoint as custodian, on any terms, any bank or entity whose business includes the safe custody of documents or
any lawyer or firm of lawyers believed by it to be of good repute and may deposit this Trust Deed, the Security Documents and any other documents with such custodian and pay all sums due in respect thereof. Neither the Trustee nor the Security Agent
shall be responsible for or required to insure against any Liability incurred in connection with such deposit and may pay all sums required to be paid on account of, or in respect of, any such deposit. The Trustee and/or the Security Agents (as the
case may be) shall not be responsible for any Liability incurred by reason of the misconduct, omission or default on the part of any custodian or nominee appointed by it in good faith hereunder and selected with due care or be bound to supervise the
proceedings or acts of such person. 

  

	14.7	Discretion: Each of the Trustee and the Security Agent will have absolute and uncontrolled discretion as to the exercise or non-exercise of its trusts, powers, authorities and
discretions under this Trust Deed (the exercise or non-exercise of which, as between the Bondholders, the Trustee and the Security Agent shall be conclusive and binding on the Bondholders) and will not be responsible for any Liability which may
result from their exercise or non-exercise. Whenever in this Trust Deed, the Security Documents, the Agency Agreement or by law, the Trustee or the Security Agent shall have discretion or permissive power it may decline to exercise the same in the
absence of approval by the Bondholders and need not exercise the same unless it has been indemnified and/or provided with security to its satisfaction. 

  

 20 

	14.8	Agents: Each of the Trustee and the Security Agent may, in the conduct of its trust business, instead of acting personally, employ and pay an agent selected by it in good faith and
with due care, whether or not a lawyer or other professional person, to transact or conduct, or concur in transacting or conducting, any business and to do or concur in doing all acts required to be done by the Trustee or, as the case may be, the
Security Agent (including the receipt and payment of money). Neither the Trustee nor the Security Agent shall be in any way responsible for any Liability incurred by reason of any misconduct or default on the part of any such agent or be bound to
supervise the proceedings or acts of any such agent. 

  

	14.9	Delegation: Whenever it thinks fit, each of the Trustee and the Security Agent may delegate by power of attorney or otherwise to any person or persons or fluctuating body of persons
(with prior written notice thereof having been given to the Issuer) on any terms (including power to sub-delegate) all or any of its trusts, powers, authorities, discretions or functions under this Trust Deed and/or the Security Documents. The
Trustee and/or the Security Agent (as the case may be) shall not be under any obligation to supervise the proceedings or acts of any such delegate or sub-delegate selected by it in good faith and with due care or be in any way responsible for any
Liability incurred by reason of any misconduct or default on the part of any such delegate or sub-delegate. The Trustee and/or the Security Agent (as the case may be) shall within a reasonable time after any such delegation or any renewal, extension
or termination thereof give notice thereof to the Issuer. 

  

	14.10	Nominees: In relation to any asset held by it under this Trust Deed and/or the Security Documents, each of the Trustee and the Security Agent may appoint any person to act as its
nominee on any terms. 

  

	14.11	Confidentiality: (a) Unless ordered to do so by a court of competent jurisdiction neither the Trustee nor the Security Agent shall be required to disclose to any Bondholder any
confidential financial or other information made available to the Trustee or the Security Agent by the Issuer and no Bondholder shall be entitled to take any action to obtain from the Trustee or the Security Agent any such information;
(b) without prejudice to paragraph (a), the Trustee may provide the Bondholders on request, all financial statements, notices, reports, opinions or other documents received by it in its capacity as Trustee under this Trust Deed and the
Conditions; (c) without prejudice to paragraph (a), each of the Trustee and the Security Agent in seeking instructions from the Bondholders in accordance with this Trust Deed shall be at liberty to disclose to the Bondholders any notice,
report, opinion or other document received by it in its capacity as Trustee or Security Agent (as the case may be) as it considers necessary in order to ensure that the Bondholders are properly informed for the purposes of giving such instructions
to the Trustee or the Security Agent (as the case may be); and (d) neither the Trustee nor the Security Agent shall have any obligation to consider, review or investigate any reports, documents or other information provided by the Issuer and
shall incur no Liability by not so doing. The Trustee and the Security Agent shall have no obligation to request any reports, documents or other information from the Issuer or third parties unless and until it is requested to do so by the
Bondholders in writing or pursuant to a resolution passed in a meeting of the Bondholders. 

  

	14.12	Determinations Conclusive: As between itself and the Bondholders the Trustee may determine all questions and doubts arising in relation to any of the provisions of this Trust Deed.
The Security Agent as between itself and the Trustee and the Bondholders may determine all questions and doubts arising in relation to any of the provisions of the Security Documents to which it is a party. Every such determination, whether made
upon such a question actually raised or implied in the acts or proceedings of the Trustee or the Security Agent, and whether relating in whole or in part to the acts or proceedings of the Trustee and/or the Security Agent (as the case maybe), will
be conclusive and shall bind the Trustee, the Security Agent and the Bondholders. 

  

 21 

	14.13	Currency Conversion: Where it is necessary or desirable to translate or convert any sum from one currency to another, it will (unless otherwise provided hereby or required by law)
be converted or translated at such rate or rates, in accordance with such method and as at such date as may be specified by the Trustee but having regard to current rates of exchange, if available. Any rate, method and date so specified will be
binding on the Issuer, the Security Agent and the Bondholders. 

  

	14.14	Payment for and Delivery of Bonds: Neither the Trustee nor the Security Agent will be responsible for the receipt or application by the Issuer of the proceeds of the issue of the

to determine the nature or extent of any such adjustment when made or the method used or to be used in making it. 

  

	14.16	The Shares: Neither the Trustee nor the Security Agent shall have any duty or responsibility at any time in respect of the validity or value (or the kind or amount) of the Shares or
any other property which may at any time be issued or delivered on the conversion of any Bonds or the sale or other disposal of any Shares. Neither the Trustee nor the Security Agent shall be responsible for any failure of the Issuer to make
available or deliver any Shares, share certificates or any other securities or property or make any payment on the exercise of any Conversion Right. 

  

	14.17	Responsibility: Neither the Trustee nor the Security Agent assumes any responsibility for the correctness of Recital (A) to this Trust Deed which shall be taken as a statement
by the Issuer, nor shall the Trustee and the Security Agent by the execution of this Trust Deed be deemed to make any representation as to the validity, sufficiency or enforceability of the Bonds. Without limitation to the preceding sentence,
neither the Trustee nor the Security Agent shall be responsible for, or for investigating or monitoring any matter which is the subject of, any recital, statement, representation, warranty or covenant of any person contained in this Trust Deed, any
other Finance Document or any other agreement or document relating to the transactions contemplated in this Trust Deed or under such other Finance Document or other agreement or document and the Trustee and the Security Agent shall assume the
accuracy and correctness thereof or for the execution, legality, effectiveness, adequacy, genuineness, validity or enforceability or admissibility in evidence of the Trust Deed, the other Finance Documents and any such agreement or other document or
any security constituted thereby or pursuant thereto.

Trust Deed or any Security Document or payment of the Bonds after the Bonds have become due and payable nor to declare the Bonds due and payable nor to enforce any of the security under the Security Documents nor to take any other action under this
Trust Deed, any Security Document or the Bonds unless it shall have been directed or requested to do so by an Extraordinary Resolution or in writing by the holders of at least one-quarter in principal amount of the Bonds then outstanding and, in
either case, it shall have been indemnified and/or secured to its satisfaction. 

  

	14.19	Consolidation, amalgamation etc.: The Trustee shall not be responsible for any consolidation, amalgamation, merger, reconstruction or scheme of the Issuer or any sale or transfer of
all or substantially all of the assets of the Issuer or the form or substance of any plan relating thereto or the consequences thereof to any Bondholder. 

  

	14.20	 Forged Bonds and Documents: Neither the Trustee nor the Security Agent shall be liable to the Issuer or any Bondholder if it has accepted as valid or has not
rejected any Certificates or Bonds purporting to be such and subsequently found to be forged

or not authentic nor shall it be liable for any action taken or omitted to be taken in reliance on any document, certificate or communication believed by it
to be genuine and to have been presented or signed by the proper parties. 

  

	14.21	Consent: Any consent or approval given by the Trustee or the Security Agent for the purposes of this Trust Deed or any Security Documents may be given on such terms and subject to

Security Agent may give any consent or approval, exercise any power, authority or discretion or take any similar action (whether or not such consent, approval, power, authority, discretion or action is specifically referred to in this Trust Deed or

reason of the Appointee’s misconduct or default or the misconduct or default of any substitute appointed by the Appointee. 

  

	14.24	Error of Judgment: Neither the Trustee nor the Security Agent shall be liable for any error of judgment made in good faith by any officer or employee of the Trustee or, as the case
may be, the Security Agent assigned by the Trustee or the Security Agent to administer its corporate trust matters. 

  

	14.25	Professional Charges: Any trustee of this Trust Deed being a banker, lawyer, accountant, broker or other person engaged in any profession or business shall be entitled to charge and

liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), whether or not foreseeable, even if the Trustee or the Security Agent has been advised of the likelihood of
such loss or damage, unless the claim for loss or damage is made in respect of its own fraud, gross negligence or wilful default. 

  

	14.27	 Reliance: Any certificate or report of any expert called for by or provided to the Trustee or the Security Agent (whether or not addressed to the Trustee or the
Security Agent) in accordance with or for the purposes of the Conditions or the Trust Deed or the Security Documents may be relied upon by the Trustee or, as the case may be, the Security Agent as sufficient evidence of the facts therein and shall,
in absence of manifest error, be conclusive and binding on all parties and neither the Trustee nor the Security Agent shall be responsible for any loss occasioned by acting on any such certificate or report. Each of the Trustee and 

  

 23 

	 	 
the Security Agent shall be entitled to rely on any report of accountants, financial advisers or investment bank where the Issuer procures the delivery of
the same pursuant to its obligations to do so under the Conditions, this Trust Deed or the Security Documents and such report shall be binding on the Issuer and the holders of the Bonds in the absence of manifest error. 

 

	14.28	Certificates from clearing systems: The Trustee may call for any certificate or other document to be issued by Clearstream, Luxembourg or Euroclear (or any alternative clearing
system on behalf of whom the Global Certificate may be held) as to the principal amount of Bonds evidenced by the Global Certificate standing to the account of any person. Any such certificate or other document shall, in the absence of manifest
error, be conclusive and binding for all purposes. The Trustee and the Security Agent shall not be liable to any person by reason of having accepted as valid or not having rejected any certificate or other document to such effect purporting to be
issued by Clearstream, Luxembourg or Euroclear (or any such alternative clearing system) and subsequently found to be forged or not authentic or not to be correct.

have regard to any interests arising from circumstances particular to individual Bondholders (whatever their number), and, in particular but without limitation, shall not have regard to the consequences of such exercise for individual Bondholders
resulting from their being for any purpose domiciled or resident in, or otherwise connected with, or subject to the jurisdiction of, any particular territory or any political sub-division thereof and the Trustee shall not be entitled to require, nor
shall any Bondholder be entitled to claim, from the Issuer (except to the extent provided for in Condition 11), the Trustee or any other person any indemnification or payment in respect of any tax consequence of any such exercise upon individual
Bondholders.

commenting upon the content of any such legal opinion and shall not be responsible for any Liability incurred thereby. 

  

	14.32	Neither the Trustee nor the Security Agent shall be bound to take any action in connection with this Trust Deed or the Security Documents or any obligations arising pursuant
thereto, including, without prejudice to the generality of the foregoing, forming any opinion or employing any financial adviser, where it is not reasonably satisfied that it will be indemnified against all Liabilities which may be incurred in
connection with such action and may demand prior to taking any such action that there be paid to it in advance such sums as it reasonably considers (without prejudice to any further demand) shall be sufficient so to indemnify it.

  

	14.33	The Trustee shall have no responsibility whatsoever to the Issuer or any Bondholder or any other person for the maintenance of or failure to maintain any rating of any of the Bonds
by any rating agency.

amounts standing to the credit of the accounts comprised therein or any part thereof or for any other reason whatsoever and whether as mortgagee in possession or on any other basis whatsoever be liable to account for any thing except actual receipts
or be liable for any loss or damage arising from realisation of, or enforcement of rights in respect of, the Collateral or any part thereof or from any act, default or omission in relation to the Collateral or any part thereof or from any exercise
or non-exercise by it of any power, authority or discretion conferred upon it in relation to the Collateral or any part thereof by or pursuant to this Trust Deed or otherwise unless such loss or damage shall be caused by its own fraud, gross
negligence or wilful default.

to any Bondholder. 

  

	14.38	Neither the Trustee nor the Security Agent shall be under any obligation to insure the Collateral or any certificate, note, bond or other evidence in respect thereof, or to require

discretion or power, take any action, make any decision, form any opinion or give any direction pursuant to this Trust Deed or otherwise in respect of the Finance Documents (including, without limitation, any such exercise of discretion or power, or
the taking of any action, the making of any decision or giving of direction in the name of the Issuer or any other Obligor pursuant to the provisions of the Security Documents), the Trustee and/or the Security Agent (as the case may be) shall be

or refraining from acting under or in relation to this Trust Deed or any Security Documents. 
  

	18.	MODIFICATION 

  

	(a)	 The Trustee may (but is not obliged to) agree with the Issuer without the consent of the Bondholders to any modification to this Trust Deed, any Security Documents,
the Agency Agreement and/or any other Finance Document, which in the Trustee’s opinion, is of a formal, minor or technical nature or to correct a manifest or (to the satisfaction of the Trustee) proven error or is to comply with mandatory
provisions of law. The Trustee may (but is not obliged to) also agree with the Issuer without the 

  

 27 

	 	 
consent of the Bondholders to any modification to this Trust Deed or the Security Documents (other than the proviso to paragraph 18 of Schedule 3 or any
matters referred to in that proviso) which is in its opinion proper to make if, in its opinion, such modification will not be materially prejudicial to the interests of the Bondholders. Any such modification shall be binding on the Bondholders and
unless the Trustee agrees otherwise, shall be notified to the Bondholders as soon as practicable thereafter. 

  

	(b)	Any modification or supplement to this Trust Deed shall be made by an instrument in writing signed by all the parties to this Trust Deed. 

  

	(c)	Any breach of or failure to comply with any such terms and conditions as are referred to in subclause 18.1 shall constitute a default by the Issuer in the performance or observance
of a covenant or provision binding on it under or pursuant to this Trust Deed. 

  

	19.	APPOINTMENT, RETIREMENT AND REMOVAL OF THE TRUSTEE 

  

	19.1	Appointment: The Issuer has the power of appointing new trustees but no one may be so appointed unless previously approved by an Extraordinary Resolution. A trustee will at all
times be a trust corporation and it maybe the sole Trustee. Any appointment of a new Trustee will be notified by the Issuer to the Bondholders as soon as practicable. 

  

	19.2	Retirement and Removal: Any Trustee may retire at any time on giving at least 60 days’ written notice to the Issuer without giving any reason and without being responsible for
any costs occasioned by such retirement and the Bondholders may by an Extraordinary Resolution remove any Trustee provided that the retirement or removal of a sole trust corporation will not become effective until a trust corporation is appointed as
successor Trustee. If a sole trust corporation gives notice of retirement or an Extraordinary Resolution is passed for its removal, the Issuer, will use all reasonable endeavours to procure that another trust corporation be appointed as Trustee as
soon as practicable and if, after 30 days’ of such notice having been given or such Extraordinary Resolution having been passed, the Issuer has failed to do so, the Trustee shall be entitled (at the expense of the Issuer) but not obliged to
appoint another trust corporation selected by the Trustee as its successor. The protections, indemnities and immunities in this Trust Deed in favour of the Trustee shall continue to benefit the Trustee notwithstanding such Trustee’s removal or
retirement. 

  

	19.3	Co-Trustees: The Trustee may, despite Clause 19.1, by written notice to the Issuer appoint anyone to act as a separate Trustee or as a co-trustee jointly with the Trustee:

  

	 	(a)	if the Trustee considers such appointment to be in the interests of the Bondholders; 

  

	 	(b)	to conform with any legal requirement, restriction or condition in a jurisdiction in which a particular act is to be performed; or 

  

	 	(c)	to obtain a judgment or to enforce a judgment or any provision of this Trust Deed or the Security Documents in any jurisdiction. 

 The Issuer irrevocably appoints the Trustee to be its attorney in its name and on its behalf to execute any such instrument of appointment. Such a person
shall (subject always to the provisions of this Trust Deed) have such trusts, powers, authorities and discretions (not exceeding those conferred on the Trustee by this Trust Deed) and such duties and obligations as shall be conferred or imposed by
the instrument of appointment. The Trustee shall have power in like manner to remove any such person. Such reasonable remuneration as the Trustee may pay to any such person, together with any attributable Liabilities incurred by it in performing its
function as such separate trustee or co-trustee, shall for the purposes of this Trust Deed be treated as Liabilities incurred by the Trustee. 
  

 28 

	19.4	Competence of a Majority of Trustees: If there are more than two Trustees the majority of them will be competent to perform the Trustee’s functions provided the majority
includes a trust corporation. 

  

	19.5	Successor: Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor to the Trustee hereunder (provided it is a trust corporation) without
the execution or filing of any papers or any further act on the part of any of the parties hereto. 

  

	20.	APPOINTMENT, RETIREMENT AND REMOVAL OF THE SECURITY AGENT 

  

	20.1	Appointment: 

  

	 	(a)	The Issuer hereby appoints DB Trustees (Hong Kong) Limited as security agent and DB Trustees (Hong Kong) Limited hereby accepts such appointment and shall so act for and on behalf
of the Bondholders and the other Secured Parties, and in connection therewith, shall hold the security constituted by the Security Documents on trust for the Secured Parties. 

  

	 	(b)	The parties hereto agree and acknowledge that: 

  

	 	(i)	the powers and benefits conferred on the Trustee by this Trust Deed shall similarly be vested in the Security Agent for the benefit of the Bondholders and shall be without prejudice
to the powers and benefits vested in the Security Agent pursuant to the Security Documents and under general law; and 

  

	 	(ii)	the Security Agent shall have all the protections enjoyed by the Trustee under the Trust Deed, including in particular and without limitation, the benefit of any right to be
indemnified as if the Security Agent was also expressly stated to be a beneficiary of any such indemnity. 

  

	 	(c)	Any reference in this Trust Deed and the Security Documents that allows the Security Agent to exercise certain discretions should not be construed as an obligation of the Security
Agent to exercise the same. 

  

	20.2	Retirement and Removal: The Security Agent may retire at any time on giving at least 60 days’ written notice to the Issuer without giving any reason and without being
responsible for any costs occasioned by such retirement and the Bondholders may by an Extraordinary Resolution remove the Security Agent provided any such retirement or removal will not become effective until a successor Security Agent is appointed.
If the Security Agent gives notice of retirement or an Extraordinary Resolution is passed for its removal, the Issuer will use all reasonable endeavours to procure that a successor Security Agent be appointed as soon as practicable and if, after 30
days’ of such notice having been given or such Extraordinary Resolution having been passed, the Issuer has failed to do so, the Security Agent shall be entitled (at the expense of the Issuer) but not obliged to appoint another entity selected
by the Security Agent as its successor. The protections, indemnities and immunities in this Trust Deed in favour of the Security Agent shall continue to benefit the Security Agent notwithstanding such Security Agent’s removal or retirement.

  

	20.3	Successor: Any corporation into which the Security Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Security Agent shall be a party, or any corporation succeeding to all or substantially all the business of the Security Agent, shall be the successor to the Security Agent hereunder without the execution or
filing of any papers or any further act on the part of any of the parties hereto.

	24.2	In case any action shall be brought against any Relevant Party in respect of which recovery may be sought from the Issuer under this Clause 24, the Trustee shall promptly notify the
Issuer in writing but failure to do so will not relieve the Issuer from any liability under this Trust Deed. 

  

	24.3	The Issuer shall not, without the prior written consent of the Relevant Party, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened
claim or action in respect of which recovery may be sought hereunder (whether or not any Relevant Party is an actual or potential party to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each

otherwise than on the last day of any Interest Period applicable to it. 

  

 32

applicable Interest Period for that Bond or overdue amount if the principal or overdue amount received had been paid on the last day of that Interest Period; 

 exceeds 
  

	 	(ii)	the amount which that Bondholder would be able to obtain by placing an amount equal to the amount received by it on deposit with a leading bank in the appropriate interbank market
for a period starting on the business day (as defined in Clause 21) following receipt and ending on the last day of the applicable Term.

	26.1	Governing Law: This Trust Deed shall be governed by and construed in accordance with English law.

	26.3	Jurisdiction: The courts of England are to have non-exclusive jurisdiction to settle any disputes which may arise out of or in connection with this Trust Deed or the Bonds and
accordingly any legal action or proceedings arising out of or in connection with this Trust Deed or the Bonds (Proceedings) may be brought in such courts. The Issuer irrevocably submits to the jurisdiction of such courts and waives any
objections to Proceedings in such courts on the ground of venue or on the ground that the Proceedings have been brought in an inconvenient forum. This submission is for the benefit of the Trustee and each of the Bondholders and shall not limit the
right of any of them to take Proceedings in any other court of competent jurisdiction nor shall the taking of Proceedings in any one or more jurisdictions preclude the taking of Proceedings in any other jurisdiction (whether concurrently or not).

  

	26.4	Service of Process: The Issuer irrevocably appoints Brandmine 3 Limited (Company Registration No. 05575723), whose registered office is currently situated at 8 Lower John
Street, Golden Square, London, W1F 9AU, England to receive, for it and on its behalf, service of process in any Proceedings in England. Such service shall be deemed completed on delivery to such process agent whether or not it is forwarded to and
received by the Issuer. If such process agent ceases to be able to act as such or no longer has an address in England, the Issuer will appoint a substitute process agent acceptable to the Trustee and will immediately notify the Trustee of such
appointment. Nothing shall affect the right to serve process in any other manner permitted by law. 

  

	27.	COUNTERPARTS

trust deed thereto) may be executed in counterparts, which when taken together shall constitute one and the same instrument.

 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 will appear on the reverse of each of the Certificates evidencing the Bonds: 
 The issue of the Tranche A U.S.$20,000,000 aggregate principal amount of Floating Rate Secured Bonds due 2009 (the Bonds) of Asia Silicon Technology Holdings Inc.
(the Issuer), and the creation of the Security (as defined in Condition 1.5), was authorised by a resolution of the board of directors of the Issuer passed on 5 September 2007. The Bonds are constituted by a trust deed dated
10 September 2007 (the Trust Deed) made between the Issuer, DB Trustees (Hong Kong) Limited as trustee for the holders of the Bonds (the Trustee, which term shall, where the context so permits, include all other persons or
companies for the time being acting as trustee or trustees under the Trust Deed) and DB Trustees (Hong Kong) Limited as security agent for the Secured Parties (the Security Agent) and are subject to the paying and conversion agency agreement

S.A. as registrar (the Registrar) and the other paying, conversion and transfer agents appointed under it (each a Paying Agent, Conversion Agent, Transfer Agent and together with the Registrar and the Principal Agent, the Agents)
relating to the Bonds. References to the Principal Agent, Registrar and Agents below are references to the principal agent, registrar and agents for the time being for the Bonds. The statements in these terms and conditions of the Bonds
(these Conditions) include summaries of, and are subject to, the detailed provisions of the Trust Deed and the Agency Agreement. Unless otherwise defined, terms used in these Conditions have the meanings specified in the Trust Deed, the
Security Agreement dated 10 September 2007 (the Issuer Security Agreement) between the Issuer and the Security Agent and the other Finance Documents (as defined in the Trust Deed) other than the Subscription Agreement. Copies of the
Trust Deed, the Agency Agreement, the Issuer Security Agreement and the other Finance Documents are available for inspection during normal business hours at the registered office of the Trustee being as at the date hereof at 55th Floor, Cheung Kong
Center, 2 Queen’s Road Central, Hong Kong and at the specified offices of each of the Agents. The Bondholders are bound by, and are deemed to have notice of, all the provisions of the Trust Deed, the Agency Agreement, the Issuer Security
Agreement and the other Finance Documents applicable to them. 
 The owners shown in the records of Euroclear Bank, S.A./N.V., as operator of the
Euroclear System (Euroclear), Clearstream Banking, société anonyme (Clearstream, Luxembourg) of book-entry interests in Bonds are entitled to the benefit of, and are bound by, and are deemed to
have notice of, all the provisions of the Trust Deed and the Agency Agreement applicable to them. 
  

	1.	Status and Security 

  

	1.1	Subject as provided in this Condition 1 and Condition 6, the Bonds constitute direct, unsubordinated, unconditional and secured obligations of the Issuer and shall at all times rank
pari passu without any preference or priority among themselves. 

  

	1.2	The Issuer has credited to an account (the Interest Reserve Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the
Issuer Security Agreement the sum of U.S.$4,200,000 out of the proceeds of the issue of the Bonds and the Tranche B Bonds. Pursuant to the Issuer Security Agreement, the Interest Reserve Account is charged to the Security Agent as security for all
amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Pursuant to the Issuer Security Agreement, such moneys,
once deposited, may only be withdrawn from the Interest Reserve Account by the Issuer and released from the security constituted by the Issuer Security Agreement in accordance with the Issuer Security Agreement. If and to the extent that such moneys
are not released from the Interest Reserve Account as aforesaid by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to require such moneys to be applied in redeeming their Bonds pursuant to Condition 10.

  

 37 

	1.3	The Issuer has credited to an account (the Escrow Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the Issuer
Security Agreement the remainder of the proceeds of the issue of the Bonds and the Tranche B Bonds (after deducting the funds credited into the Interest Reserve Account). Pursuant to the Issuer Security Agreement, the Escrow Account is charged to
the Security Agent as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Such moneys may only be withdrawn from
the Escrow Account for the purposes set out in Condition 6.21(a)(ii) to 6.21(a)(v) and in accordance with the procedures set forth in the Issuer Security Agreement and subject to all of the conditions set forth in the Issuer Security Agreement being
satisfied, provided that if and to the extent that such moneys standing to the credit of the Escrow Account are not so released from the Escrow Account by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to
require such moneys to be applied in redeeming their Bonds pursuant to Condition 10. 

  

	1.4	The Bonds will have the benefit of the Security (as defined in Condition 1.5) as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK)
to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. On the Issue Date, the Issuer will (simultaneously with the issue of the Bonds) issue the Tranche B Bonds (as defined in the Trust Deed). The
Tranche B Bonds will have the benefit of the same security as the Bonds, and the payment obligations of the Issuer under the Bonds shall at all times rank at least equally with its payment obligations under the Tranche B Bonds. The Security Agent or
its nominee will hold the Security for the benefit of the Bondholders and the holders of the Tranche B Bonds pursuant to the provisions of the Trust Deed. 

  

	1.5	The security constituted by the Security Documents (the Security) shall become immediately enforceable if an Event of Default occurs, following which the Security Agent may,
but shall not be bound (except as provided in Condition 15 and provided it has been indemnified and/or secured to its satisfaction) to take such proceedings or other action as it shall, in its discretion, think fit to enforce the Security (or any
part thereof) and the provisions of the Trust Deed and the Security Documents. The Trust Deed and the Security Documents provide that the net proceeds resulting from the enforcement of the Security, after the remuneration of the Trustee and/or any
Appointee, the Security Agent and any Receiver, and the Agents and all their respective costs, charges, liabilities and expenses and any taxes and other amounts required to be paid prior to any such application, be applied pro rata in meeting claims
of any Bondholders or holders in respect of the Tranche B Bonds whose Bonds or, as the case may be, Tranche B Bonds are then outstanding. 

  

	2.	Form and Denomination 

 The Bonds are issued in
registered form in the denomination of U.S.$100,000 each and integral multiples of U.S.$1,000 (referred to as the principal amount of a Bond) in excess thereof (the authorised denomination). A Bond certificate (each a Certificate)
will be issued to each Bondholder in respect of its registered holding of Bonds. Each Certificate will be numbered serially with an identifying number which will be recorded on the relevant Certificate and in the Register (as defined in
Condition 4.1) which the Issuer will procure to be kept by the Registrar. 
  

	3.	Title 

 Title to the Bonds passes only by
registration in the Register (as defined in Condition 4.1). The holder of any Bond will (except as otherwise required by law) be treated as its absolute owner for all purposes (whether or not it is overdue and regardless of any notice of ownership,
trust or any interest in it or any writing on, or the theft or loss of, the Certificate issued in respect of it) and no person will be liable for so treating the holder. In these Conditions Bondholder and (in relation to a Bond) holder
mean the person in whose name a Bond is registered. 
  

 38 

	4.	Transfers of Bonds; Issue of Certificates 

  

	4.1	Register 

 The Issuer will
cause to be kept at the specified office outside the United Kingdom and Hong Kong of the Registrar and in accordance with the terms of the Agency Agreement a register on which shall be entered the names and addresses of the holders of the Bonds and
the particulars of the Bonds held by them and of all transfers of the Bonds (the Register). Each Bondholder shall be entitled to receive only one Certificate in respect of its entire holding of Bonds. 
  

	4.2	Transfer

payable in respect of interest on the principal amount of each Bond for the relevant Interest Period. The Interest Amount shall be determined by applying the Rate of Interest to the principal amount of a Bond, multiplying the sum by the actual
number of days in the Interest Period concerned divided by 360 and rounding the resultant figure to the nearest cent (half a cent being rounded upwards).

Principal Agent defaults at any time in its obligation to determine the Rate of Interest and Interest Amount in accordance with the above provisions, the Trustee shall determine (a) the Rate of Interest at such rate as, in its absolute
discretion (having such regard as it shall think fit to the procedure described above), it shall deem fair and reasonable in all the circumstances and (b) the Interest Amount in the manner provided in Condition 7.2 above, and all such

Issuer or the Bondholders shall attach to the Reference Banks (or any of them), the Principal Agent or, if applicable, the Trustee in connection with the exercise or non-exercise by any of them of their powers, duties and discretions under this
Condition 7. 
  

	7.6	Principal Agent

that, so long as any of the Bonds remains outstanding, there is at all times a Principal Agent for the purposes of the Bonds and the Issuer may, subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld,

Interest Amount for any Interest Period, the Issuer shall, subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld, delayed or refused), appoint the London office of another major bank engaged in the

date specified in the Tax Redemption Notice (the Tax Redemption Date) if (i) the Issuer satisfies the Trustee immediately prior to the giving of such Tax Redemption Notice that the Issuer has or will become obliged to pay additional
amounts as referred to in Condition 11 as a result of any change in, or amendment to, the laws or regulations of the relevant jurisdiction, or any change in the general application or official interpretation of such laws or regulations, which change
or amendment becomes effective on or after the Issue Date, and (ii) such obligation cannot be avoided by the Issuer taking reasonable measures available to it, provided that no Tax Redemption Notice shall be given earlier than 90 days prior to

evidence thereof in which event it shall be conclusive and binding on the Bondholders. 

  

	(b)	If the Issuer gives a Tax Redemption Notice pursuant to Condition 10.2(a), each Bondholder will have the right to elect that its Bond(s) shall not be redeemed and that the
provisions of Condition 11 shall not apply in respect of any payment of principal, premium (if any) or interest to be made in respect of such Bond(s) which falls due after the relevant Tax Redemption Date whereupon no additional amounts shall be
payable in respect thereof pursuant to Condition 11 and payment of all amounts shall be made subject to the deduction or withholding of any tax required to be deducted or withheld (provided that such election shall only be in respect of the
deduction or withholding then required to be made and the Issuer shall comply with the provisions of Condition 11 in respect of any further deductions or withholding). To exercise a right pursuant to this Condition 10.2, the holder of the relevant
Bond must complete, sign and deposit at the specified office of any Paying Agent a duly completed and signed notice of exercise, in the form for the time being current, obtainable from the specified office of any Paying Agent together with the

compelled by law. In such event, the Issuer will pay such additional amounts as will result in the receipt by the Bondholders and other Finance Parties of the net amounts after such deduction or withholding equal to the amounts which would otherwise
have been receivable by them had no such deduction or withholding been required except that no such additional amount shall be payable in respect of any Bond: 

  

	 	(i)	to a holder (or to a third party on behalf of a holder) who is subject to such taxes, duties, assessments or governmental charges in respect of such Bond by reason of his having

	 	(ii)	(in the case of a payment of principal) if the Certificate in respect of such Bond is surrendered more than 30 days after the relevant date except to the extent that the holder
would have been entitled to such additional amount on surrendering the relevant Certificate for payment on the last day of such period of 30 days; 

  

	 	(iii)	where such withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to European Council Directive 2003/48/EC or any law implementing or
complying with, or introduced in order to conform to, such Directive; or 

  

	 	(iv)	presented for payment by or on behalf of a Bondholder who would have been able to avoid such withholding or deduction by presenting the relevant Bond to another Paying Agent in a
Member State of the European Union. 

 For the purposes this paragraph (a): 
 relevant date means whichever is the later of (a) the date on which such payment first becomes due and (b) if the full amount payable has
not been received by the Trustee or the Principal Agent on or prior to such due date, the date on which, the full amount having been so received, notice to that effect shall have been given to the Bondholders and cheques despatched or payment made.

 References in these Conditions to principal, premium (if any) and interest, and any other amounts to be paid by the Issuer under the Bonds,
shall be deemed also to refer to any additional amounts which may be payable under this Condition or any undertaking or covenant given in addition thereto or in substitution therefor pursuant to the Trust Deed. 
  

	(b)	If the Issuer makes a Tax Payment and a Bondholder (in its absolute discretion) determines that: 

  

	 	(i)	a Tax Credit is attributable to that Tax Payment; and 

  

	 	(ii)	it has used and retained that Tax Credit, 

  

 72 

 the relevant Bondholder must pay an amount to the Issuer which that Bondholder determines (in its
absolute discretion) will leave it (after that payment) in the same after-tax position as it would have been if the Tax Payment had not been required to be made by the Issuer.

any such consent as aforesaid, that any Event of Default or Potential Event of Default (as defined in the Trust Deed) shall not be treated as such (provided that, in any such case, it is not, in the opinion of the Trustee, materially prejudicial to
the interests of the Bondholders). Any such modification, waiver, authorisation or determination will be binding on the Bondholders and, unless the Trustee agrees otherwise, any such modifications will be notified by the Issuer to the Bondholders as
soon as practicable thereafter.

 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 will appear on the reverse of each of the Certificates evidencing the Bonds: 
 The issue of the Tranche B U.S.$40,000,000 aggregate principal amount of Floating Rate Secured Convertible Bonds due 2009 (the Bonds) of Asia Silicon Technology
Holdings Inc. (the Issuer), and the creation of the Security (as defined in Condition 1.5), was authorised by a resolution of the board of directors of the Issuer passed on 5 September 2007. The Bonds are constituted by a trust deed
dated 10 September 2007 (the Trust Deed) made between the Issuer, DB Trustees (Hong Kong) Limited as trustee for the holders of the Bonds (the Trustee, which term shall, where the context so permits, include all other persons or
companies for the time being acting as trustee or trustees under the Trust Deed) and DB Trustees (Hong Kong) Limited as security agent for the Secured Parties (the Security Agent) and are subject to the paying and conversion agency agreement
dated 10 September 2007 (the Agency Agreement) entered into between the Issuer, the Trustee, Deutsche Bank AG, Hong Kong Branch as principal paying, conversion and transfer agent (the Principal Agent) and Deutsche Bank Luxembourg
S.A. as registrar (the Registrar) and the other paying, conversion and transfer agents appointed under it (each a Paying Agent, Conversion Agent, Transfer Agent and together with the Registrar and the Principal Agent, the
Agents) relating to the Bonds. References to the Principal Agent, Registrar and Agents below are references to the principal agent, registrar and agents for the time being for the Bonds. The statements in these terms and
conditions of the Bonds (these Conditions) include summaries of, and are subject to, the detailed provisions of the Trust Deed and the Agency Agreement. Unless otherwise defined, terms used in these Conditions have the meanings specified in
the Trust Deed, the Security Agreement dated 10 September 2007 (the Issuer Security Agreement) between the Issuer and the Security Agent and the other Finance Documents (as defined in the Trust Deed) other than the Subscription
Agreement. Copies of the Trust Deed, the Agency Agreement, the Issuer Security Agreement and the other Finance Documents are available for inspection during normal business hours at the registered office of the Trustee being as at the date hereof at
55th Floor, Cheung Kong Center, 2 Queen’s Road Central, Hong Kong and at the specified offices of each of the Agents. The Bondholders are bound by, and are deemed to have notice of, all the provisions of the Trust Deed, the Agency Agreement,
the Issuer Security Agreement and the other Finance Documents applicable to them. 
 The owners shown in the records of Euroclear Bank, S.A./N. V., as
operator of the Euroclear System (Euroclear), Clearstream Banking, société anonyme (Clearstream, Luxembourg) of book-entry interests in Bonds are entitled to the benefit of, and are bound by,
and are deemed to have notice of, all the provisions of the Trust Deed and the Agency Agreement applicable to them. 
  

	1.	Status and Security 

  

	1.1	Subject as provided in this Condition 1 and Condition 6, the Bonds constitute direct, unsubordinated, unconditional and secured obligations of the Issuer and shall at all times
rank pari passu without any preference or priority among themselves. 

  

	1.2	The Issuer has credited to an account (the Interest Reserve Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the
Issuer Security Agreement the sum of U.S.$4,200,000 out of the proceeds of the issue of the Bonds and the Tranche A Bonds. Pursuant to the Issuer Security Agreement, the Interest Reserve Account is charged to the Security Agent as security for all
amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Pursuant to the Issuer Security Agreement, such moneys,
once deposited, may only be withdrawn from the Interest Reserve Account by the Issuer and released from the security constituted by the Issuer Security Agreement in accordance with the Issuer Security Agreement. If and to the extent that such moneys
are not released from the Interest Reserve Account as aforesaid by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to require such moneys to be applied in redeeming their Bonds pursuant to Condition 10.

  

 87 

	1.3	The Issuer has credited to an account (the Escrow Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the Issuer
Security Agreement the remainder of the proceeds of the issue of the Bonds and the Tranche A Bonds (after deducting the funds credited into the Interest Reserve Account). Pursuant to the Issuer Security Agreement, the Escrow Account is charged to
the Security Agent as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Such moneys may only be withdrawn from
the Escrow Account for the purposes set out in Condition 6.21(a)(ii) to 6.21(a)(v) and in accordance with the procedures set forth in the Issuer Security Agreement and subject to all of the conditions set forth in the Issuer Security Agreement being
satisfied, provided that if and to the extent that such moneys standing to the credit of the Escrow Account are not so released from the Escrow Account by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to
require such moneys to be applied in redeeming their Bonds pursuant to Condition 10. 

  

	1.4	The Bonds will have the benefit of the Security (as defined in Condition 1.5) as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK)
to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. On the Issue Date, the Issuer will (simultaneously with the issue of the Bonds) issue the Tranche A Bonds (as defined in the Trust Deed). The
Tranche A Bonds will have the benefit of the same security as the Bonds, and the payment obligations of the Issuer under the Bonds shall at all times rank at least equally with its payment obligations under the Tranche A Bonds. The Security Agent or
its nominee will hold the Security for the benefit of the Bondholders and the holders of the Tranche A Bonds pursuant to the provisions of the Trust Deed. 

  

	1.5	The security constituted by the Security Documents (the Security) shall become immediately enforceable if an Event of Default occurs, following which the Security Agent may,
but shall not be bound (except as provided in Condition 15 and provided it has been indemnified and/or secured to its satisfaction) to take such proceedings or other action as it shall, in its discretion, think fit to enforce the Security (or any
part thereof) and the provisions of the Trust Deed and the Security Documents. The Trust Deed and the Security Documents provide that the net proceeds resulting from the enforcement of the Security, after the remuneration of the Trustee and/or any
Appointee, the Security Agent and any Receiver, and the Agents and all their respective costs, charges, liabilities and expenses and any taxes and other amounts required to be paid prior to any such application, be applied pro rata in meeting claims
of any Bondholders or holders in respect of the Tranche A Bonds whose Bonds or, as the case maybe, Tranche A Bonds are then outstanding. 

  

	2.	Form and Denomination 

  

	2.1	The Bonds are issued in registered form in the denomination of U.S.$100,000 each and integral multiples of U.S.$1,000 (referred to as the principal amount of a Bond) in
excess thereof (the authorised denomination). A Bond certificate (each a Certificate) will be issued to each Bondholder in respect of its registered holding of Bonds. Each Certificate will be numbered serially with an identifying
number which will be recorded on the relevant Certificate and in the Register (as defined in Condition 4.1) which the Issuer will procure to be kept by the Registrar. 

  

	2.2	Each Bond will entitle its registered holder, following the occurrence of a Complying IPO (as defined in Condition 8), to convert such Bond into Shares (as defined in Condition
8.1(d)) as described in Condition 8. 

 Pursuant to a registration rights agreement dated on or about the Issue Date between
the Issuer, Mandra Materials Limited, Deutsche Bank AG and the Subsequent Shareholders named therein (the Registration Rights Agreement), the Issuer is 

  

 88 

 
required to effect registration in respect of the Shares under the Securities Act (as defined in Condition 6.28) at the time and in a manner set out in
the Registration Rights Agreement. The transferability of the Shares are subject to the restrictions set out in the Registration Rights Agreement and the Securities Act. 
  

	3.	Title 

 Title to the Bonds passes only by
registration in the Register (as defined in Condition 4.1). The holder of any Bond will (except as otherwise required by law) be treated as its absolute owner for all purposes (whether or not it is overdue and regardless of any notice of ownership,
trust or any interest in it or any writing on, or the theft or loss of, the Certificate issued in respect of it) and no person will be liable for so treating the holder. In these Conditions Bondholder and (in relation to a Bond) holder
mean the person in whose name a Bond is registered.

	4.1	Register

at the specified office outside the United Kingdom and Hong Kong of the Registrar and in accordance with the terms of the Agency Agreement a register on which shall be entered the names and addresses of the holders of the Bonds and the particulars

Registration Rights Agreement in respect of that Bond, and provided further that so long as no Event of Default is subsisting, a Bond may not be transferred, without the prior consent of the Issuer, to a person specified in a letter dated the Issue
Date addressed by the Issuer to, and accepted by, the Manager in respect of this Condition 4.2. A Bond may be transferred by delivery of the Certificate issued in respect of that Bond, with the form of transfer on the back duly completed and signed

transfer, be mailed by uninsured mail at the risk of the holder entitled to the Bonds and at the Issuer’s expense to the address specified in the form of transfer.

Certificate in respect of the Bonds not so transferred, exchanged or converted will, within five business days of receipt of the original Certificate by the Registrar or other relevant Agent, be made available for collection at the specified office
of the Registrar or such other relevant Agent or, if so requested in the form of transfer, be mailed by uninsured mail at the risk of the holder of the Bonds not so transferred and at the Issuer’s expense to the address of such holder appearing

below); 

  

	 	(ii)	the Rate of Interest for the relevant Interest Period shall be the Screen Rate plus the Margin (as defined below) or, if the Screen Rate is unavailable, and if at least two of the

payable in respect of interest on the principal amount of each Bond for the relevant Interest Period. The Interest Amount shall be determined by applying the Rate of Interest to the principal amount of a Bond, multiplying the sum by the actual
number of days in the Interest Period concerned divided by 360 and rounding the resultant figure to the nearest cent (half a cent being rounded upwards). 
  

	7.3	Publication of Rate of Interest and Interest Amount 

 The Principal Agent shall cause the Rate of Interest and the Interest Amount for each Interest Period and the Interest Payment Date relating to such Interest Period to be notified to the Issuer, the Trustee (by no later than the first day

	7.4	Determination by the Trustee 

 If the
Principal Agent defaults at any time in its obligation to determine the Rate of Interest and Interest Amount in accordance with the above provisions, the Trustee shall determine (a) the Rate of Interest at such rate as, in its absolute
discretion (having such regard as it shall think fit to the procedure described above), it shall deem fair and reasonable in all the circumstances and (b) the Interest Amount in the manner provided in Condition 7.2 above, and all such
determinations shall be deemed to be determinations by the Principal Agent.

Condition 7.

	8.2	Conversion Right 

  

	(a)	Conversion Period: Subject as hereinafter provided, the Bondholders have the right to convert their Bonds into Shares on the IPO Date immediately prior to the occurrence of a
Complying IPO. 

 The right of a Bondholder to convert any Bond into Shares is called the Conversion Right. Subject to,
and upon compliance with, the provisions of this Condition and Condition 8.3, the Conversion Right attaching to any Bond will be deemed to have been exercised by the holder thereof, on the last day of the Conversion Period, unless that holder has at
any time during the Conversion Period issued a Non-exercise Notice (as defined in Condition 8.3(a)) in accordance with that Condition. 
  

	(b)	Number of Shares to be converted: The number of Shares to be issued on conversion of a Bond will be determined by the following formula: 

   A x B x C   
       D 
  

 120 

 Where: 
 A is 
  

	 	(i)	(A) during the period from (and including) the Issue Date to (but excluding) 1 October 2008, 2.732 % and (B) during the period from 1 October 2008 to the

 If the number of Shares to be issued per
Bond as determined by the formula above is not a whole number, it will be rounded up to the nearest whole number. 
  

	(c)	Strike Adjustment: If the Market Capitalisation at the Complying IPO is less than the Original Valuation, in addition to the Shares issued pursuant to paragraph
(a) above, the Issuer must, on the IPO Date, pay to the Bondholder of each Bond who has exercised the Conversion Right in relation to that Bond an amount calculated in accordance with this paragraph. The amount payable for each converted Bond
under this paragraph will be determined by the following formula: 

   (X-Y) x A x C    

D

 A is 
  

	 	(i)	(A) during the period from (and including) the Issue Date to (but excluding) 1 October 2008, 2.732 % and (B) during the period from the date falling 1 October

	 	(ii)	if the EB Funding Date occurs within one month of the Issue Date, 2.232%; 

 C is the face value of the relevant converting Bond; 
 D is the aggregate face value of all Bonds
outstanding immediately before conversion at the Complying IPO; 
 X is the Original Valuation; and 
  

 121 

 Y is the Market Capitalisation, 
 and 
 Original Valuation means
U.S.$2,560,000,000; 
 Market Capitalisation will be determined by the following formula: 
 B x Z 
 Where: 
 B is the number of Shares in issue immediately before completion of the Complying IPO (excluding any Shares converted pursuant to the exercise of the
Conversion Right); and 
 Z is the issue price per Share at the Complying IPO (or, if not in U.S. dollars, its equivalent in U.S. dollars as
determined using a rate of exchange equal to the mid-exchange rate between the relevant currency and U.S. dollars quoted by Deutsche Bank AG, Hong Kong Branch or failing which any other bank of international repute selected by the Trustee at 11:00
a.m. (Hong Kong time) on the date on which the IPO price is determined). 
 If the amount as determined by the formula above is not a whole
U.S. dollar, it will be rounded up to the nearest whole U.S. dollar. 
  

	(d)	Conversion of more than one Bond: The Conversion Right may be 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. 

  

	(e)	Fractions of Shares: Fractions of Shares will not be issued on conversion and no cash adjustments will be made in respect thereof. 

  

	(f)	Revival and/or survival after Default: Notwithstanding the provisions of Condition 8.2(a), if any Bond has become due and payable prior to the Maturity Date by reason of the
occurrence of any of the events under Condition 12, the Conversion Right attaching to such Bond will revive and/or will continue to be exercisable up to, and including, the close of business (at the place where the Certificate evidencing such Bond
is deposited for conversion) on the earlier of (i) the date upon which the full amount of the moneys payable in respect of such Bond has been duly received by the Principal Agent or the Trustee and notice of such receipt has been duly given to
the Bondholders and (ii) the date falling two business days prior to the Maturity Date and, notwithstanding the provisions of Condition 8.2(a), any Bond in respect of which the Certificate and Conversion Notice (as defined in Condition 8.3) are
deposited for conversion prior to such date shall be exchanged on the relevant Conversion Date (as defined in Condition 8.3(a)) notwithstanding that the full amount of the moneys payable in respect of such Bond shall have been received by the
Principal Agent or the Trustee before such Conversion Date. 

  

	8.3	Conversion Procedure 

  

	(a)	Deemed exercise of Conversion Right: To elect not to exercise the Conversion Right attaching to any Bond, the holder thereof must complete, execute and deposit at its own
expense during business hours at the specified office of any Conversion Agent a notice of non-exercise (a Non-exercise Notice) in duplicate in the form (for the time being current) obtainable from the specified office of each Agent, during
the Conversion Period (as defined in Condition 8.2(a)). On the last day of the Conversion Period, in relation to any Bond, unless the holder thereof has elected not to exercise the Conversion Right attaching to that Bond under this paragraph (a),
that holder shall be deemed to have exercised its Conversion Rights in relation to that Bond. 

  

 122 

	(b)	Conversion Notice: Each Bondholder who is deemed under paragraph (a) above to have exercised its Conversion Right may complete, execute and deposit at its own expense
during business hours at the specified office of any Conversion Agent a notice specifying the name and address of the person in whose name the Shares issuable upon conversion are to be registered and giving other details in respect of the conversion
(a Conversion Notice) in duplicate in the form (for the time being current) obtainable from the specified office of each Agent not later than two business days prior to the Conversion Date. If a converting Bondholder fails to deliver a
Conversion Notice, the Bonds held by that Bondholder will nevertheless be converted in accordance with Condition 8.2(a). In that case the Shares will be issued in the name of that Bondholder and the certificate or certificates representing such
Shares shall be mailed to that Bondholder at its address specified in the Register. 

 The conversion date in respect of a Bond
(the Conversion Date) shall be the IPO Date. A Conversion Notice once delivered shall be irrevocable and may not be withdrawn unless the Issuer consents in writing to such withdrawal (and notified the Trustee and the Agents of such consent).

  

	(c)	Stamp Duty etc.: The Issuer must pay any taxes and capital, stamp, issue and registration duties arising on conversion (the Conversion Taxes) and the Issuer must also
pay all, if any, taxes arising by reference to any disposal or deemed disposal of a Bond in connection with such conversion and all other expenses arising on the issue of Shares on conversion. The Conversion Agent is under no obligation to determine
whether the Issuer is liable to pay any Conversion Taxes including capital, stamp, issue, registration or similar taxes and duties or the amounts payable (if any) in connection with this Condition 8.3(c). 

  

	(d)	Registration: On the Conversion Date, the Issuer will, in the case of Bonds converted on exercise of the Conversion Right, register the person or persons designated for the
purpose in the Conversion Notice as holder(s) of the relevant number of Shares in the Issuer’s share register or, if no Conversion Notice is delivered, register the converting Bondholder as holders of the relevant number of Shares in the
Issuer’s share register and will, if the Bondholder has also requested in the Conversion Notice, take all necessary actions to procure that Shares are delivered through the relevant clearing and settlement system (if any) if and for so long as
the Shares are listed on a Stock Exchange; or will make the certificate or certificates representing such Shares available for collection at the office of the Issuer’s then share registrar notified to Bondholders in accordance with Condition 19
or, if so requested in the relevant Conversion Notice, will cause its share registrar to mail (at the risk, and, if sent at the request of such person otherwise than by ordinary mail, at the expense, of the person to whom such certificate or
certificates are sent) such certificate or certificates to the person and at the place specified in the Conversion Notice, 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 certificate will be issued in respect of all Shares issued on conversion of Bonds subject to the same Conversion Notice and
which are to be registered in the same name. 

 The person or persons specified for that purpose 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 of the Bonds will in
all respects rank pari passu with the Shares in issue on the relevant Registration Date. Save as set out in these Conditions, a holder of Shares issued on conversion of Bonds shall not be entitled to any rights the record date for which
precedes the relevant Registration Date. Upon delivery of the Shares to a Bondholder in satisfaction of the Conversion Right of any converting Bondholder and the completion of such registration in accordance with this Condition 8.3, the right of
such converting Bondholder to repayment of the principal amount of the Bonds so converted shall be extinguished. 
  

 123 

	(e)	Interest Accrual: On the Conversion Date, the Issuer shall pay to each Bondholder (i) any interest otherwise accruing on converted Bonds since the Interest Payment Date
last preceding the Conversion Date, and (ii) Break Cost (as defined in the Trust Deed). 

  

	(f)	Equivalent Amounts: 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, the Issuer will pay to the Bondholder or his designee an amount (the Equivalent Amount) equal to any 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 means of a U.S. dollar cheque drawn on a bank in New York City and sent to the address specified in the relevant Conversion Notice or to the relevant Bondholder if no Conversion Notice has been delivered.

	(b)	If the Issuer gives a Tax Redemption Notice pursuant to Condition 10.2(a), each Bondholder will have the right to elect that its Bond(s) shall not be redeemed and that the
provisions of Condition 11 shall not apply in respect of any payment of principal, premium (if any) or interest to be made in respect of such Bond(s) which falls due after the relevant Tax Redemption Date whereupon no additional amounts shall be

Member State of the European Union.

not been received by the Trustee or the Principal Agent on or prior to such due date, the date on which, the full amount having been so received, notice to that effect shall have been given to the Bondholders and cheques despatched or payment made.

financial conditions of the Issuer or any of the Subsidiaries of the Issuer (either individually or taken as whole), (ii) affecting the ability of an Obligor to perform its payment obligations under the Finance Documents or (iii) affecting
the validity or enforceability of any Finance Document. 

 For the purpose of this Condition 12 business days shall mean
a day other than a Saturday or Sunday on which banks are open for business in Hong Kong. 
  

	13.	Prescription 

 Claims in respect of amounts due in
respect of the Bonds will become prescribed unless made within 10 years (in the case of principal) and five years (in the case of interest or premium (if any)) from the relevant date (as defined in Condition 10) in respect thereof. 
  

	14.	Enforcement 

 The Trustee may, at any time at its
sole discretion and without notice, take such proceedings against the Issuer as it may think fit to enforce the provisions of the Trust Deed and the Bonds and/or any other Finance Document and/or at any time after the Security shall become
enforceable to enforce the same in accordance with the Security Documents, but it will not be bound to take any such proceedings or any other action under the Trust Deed, the Bonds and/or any Security Documents unless (a) it shall have been so
directed by an Extraordinary Resolution and (b) it shall have been indemnified and/or secured to its satisfaction. No Bondholder will be entitled to proceed directly against the Issuer unless the Trustee, having become bound to do so, fails to
do so within a reasonable period and such failure shall be continuing. 
  

	15.	Meetings of Bondholders, Modification and Waiver 

  

	15.1	Meetings 

 The Trust Deed contains provisions
for convening meetings of Bondholders to consider any matter affecting their interests, including the sanctioning by Extraordinary Resolution of a modification of the Bonds or the provisions of the Trust Deed or the Security Agreement. The quorum at
any such meeting for passing an Extraordinary Resolution will be one or more persons holding or representing over 50 per cent. in principal amount of the Bonds for the time being outstanding or, at any adjourned such meeting, one or more
persons being or representing Bondholders whatever the principal amount of the Bonds so held or represented unless the business of such meeting includes consideration of proposals, inter alia, (i) to modify the due date for any payment in
respect of the Bonds, (ii) to reduce or cancel the amount of principal, premium (if any), interest or Equivalent Amount payable in respect of the Bonds, (iii) to change the currency of payment of the Bonds, (iv) to modify or cancel
the 

  

 132 

 
Conversion Right or the Security, or (v) to modify the provisions concerning the quorum required at any meeting of the Bondholders or the majority
required to pass an Extraordinary Resolution, in which case the necessary quorum for passing an Extraordinary Resolution will be one or more persons holding or representing not less than 66 per cent., or at any adjourned such meeting not less
than 33 per cent, in principal amount of the Bonds for the time being outstanding. An Extraordinary Resolution passed at any meeting of Bondholders will be binding on all Bondholders, whether or not they are present at the meeting. The Trust
Deed provides that a written resolution signed by or on behalf of the holders of not less than 66 2/3 per cent, of the aggregate principal amount of Bonds outstanding shall be as valid and effective as a duly passed Extraordinary Resolution. The Trust Deed contains
provisions for convening a single meeting of the holders of the Tranche A Bonds and the holders of the Bonds of the Issuer in certain circumstances. 
  

	15.2	Modification and Waiver 

 The Trustee may
agree, without the consent of the Bondholders, to (i) any modification (except as mentioned in Condition 15.1 above) to, or the waiver or authorisation of any breach or proposed breach of, the Bonds, the Agency Agreement, the Trust Deed or any
Security Document which is in its opinion proper to make if, in the opinion of the Trustee, it is not materially prejudicial to the interests of the Bondholders or (ii) any modification to the Bonds, the Agency Agreement, the Trust Deed or any
Security Document which, in the Trustee’s opinion, is of a formal, minor or technical nature or to correct a manifest error or (to the satisfaction of the Trustee) proven error to comply with mandatory provisions of law or determine, without
any such consent as aforesaid, that any Event of Default or Potential Event of Default (as defined in the Trust Deed) shall not be treated as such (provided that, in any such case, it is not, in the opinion of the Trustee, materially prejudicial to
the interests of the Bondholders). Any such modification, waiver, authorisation or determination will be binding on the Bondholders and, unless the Trustee agrees otherwise, any such modifications will be notified by the Issuer to the Bondholders as
soon as practicable thereafter. 
  

	16.	Interests of Bondholders 

 In connection with the
exercise of its functions (including but not limited to those in relation to any proposed modification, authorisation, waiver, determination or substitution) the Trustee shall have regard to the general interests of the holders of the Tranche A
Bonds and the holders of the Tranche B Bonds (or holders of the Tranche A Bonds or holders of the Tranche B Bonds affected thereby) as a class but shall not have regard to any interests arising from circumstances particular to individual holders of
the Tranche A Bonds or Tranche B Bonds (whatever their number) and, in particular but without limitation, shall not have regard to the consequences of such exercise for individual holders of Tranche A Bonds or Tranche B Bonds (whatever their number)
resulting from their being for any purpose domiciled or resident in, or otherwise connected with, or subject to the jurisdiction of, any particular territory or any political sub-division thereof and the Trustee shall not be entitled to require, nor
shall any holder of Tranche A Bonds or Tranche B Bonds be entitled to claim, from the Issuer or the Trustee or any other person, any indemnification or payment in respect of any tax consequences of any such exercise upon individual holders of
Tranche A Bonds or Tranche B Bonds except to the extent provided for in Condition 10 and/or any undertakings given in addition thereto or in substitution therefor pursuant to the Trust Deed. 
  

	17.	Replacement of Certificates 

 If any Certificate is
mutilated, defaced, destroyed, stolen or lost, it may be replaced at the specified office of the Registrar or any Agent upon payment by the claimant of such costs as may be incurred in connection therewith and on such terms as to evidence and
indemnity as the Issuer and such Agent may reasonably require. Mutilated or defaced Certificates must be surrendered before replacements will be issued. 
  

 133 

	18.	Agents 

 The names of the initial Agents and the
Registrar and their specified offices are set out below. The Issuer reserves the right, subject to the prior written approval of the Trustee, at any time to vary or terminate the appointment of any Agent or the Registrar and to appoint additional or
other Agents or a replacement Registrar. The Issuer will at all times maintain (a) a Principal Agent, (b) a Paying Agent with a specified office in a European Union member state that will not be obliged to withhold or deduct tax pursuant
to European Council Directive 2003/48/EC or any law implementing or complying with, or introduced in order to conform, to such Directive, and (c) a Registrar which will maintain the register of Bondholders outside the United Kingdom and Hong
Kong. Notice of any such termination or appointment, of any changes in the specified offices of any Agent or the Registrar and of any change in the identity of the Registrar or the Principal Agent will be given promptly by the Issuer to the
Bondholders and in any event not less than 45 days’ notice will be given. 
  

	19.	Notices 

 All notices to Bondholders shall be
validly given if mailed to them at their respective addresses in the Register of Bondholders maintained by the Registrar or published in a leading newspaper having general circulation in Hong Kong or, if such publication shall not be practicable, in
an English language newspaper of general circulation in Asia. Any such notice shall be deemed to have been given on the date of such publication or, as the case may be, the seventh day after being so mailed. 
 Notices to be given by any Bondholder shall be in writing and given by lodging the same, together with the relative Certificate, with the Registrar, of if
the Certificates are held in a clearing system, may be given through the clearing system in accordance with its standard rules and procedures. 
  

	20.	Indemnification 

 The Trust Deed contains provisions
for the indemnification of the Trustee and for its relief from responsibility, including provisions relieving it from taking any action unless indemnified and/or secured to its satisfaction. The Trustee is entitled to enter into business
transactions with the Issuer and any entity related to the Issuer without accounting for any profit. 
  

	21.	Contracts (Rights of Third Parties) Act 1999 

 No
person shall have any right to enforce any term or condition of the Bonds or any provision of the Trust Deed under the Contracts (Rights of Third Parties) Act 1999. 
  

	22.	Governing Law and Submission to Jurisdiction 

 The
Bonds, the Trust Deed, the Agency Agreement and the Issuer Security Agreement are governed by, and shall be construed in accordance with, the laws of England. The AST (HK) Security Agreement and the AST (HK) Share Mortgage are governed by, and will
be construed in accordance with, the laws of Hong Kong. The Equity Pledge Agreement is governed by, and will be construed in accordance with, the laws of the PRC. In relation to any legal action or proceedings arising out of or in connection with
the Trust Deed or the Bonds (together referred to as Proceedings), the Issuer has in the Trust Deed irrevocably submitted to the non-exclusive jurisdiction of the courts of England and in relation thereto, and the Issuer has appointed
Brandmine 3 Limited at 8 Lower John Street, Golden Square, London W1F 9AU, England, as agent for service of process in England. The Trustee and the Bondholders may take any Proceedings against the Issuer in any other court of competent jurisdiction

 SCHEDULE 3 
 PROVISIONS FOR MEETINGS OF BONDHOLDERS 
  

	2.	A holder of a Bond may by an instrument in writing (a form of proxy) in the form available from the specified office of any Agent in English signed by the holder or, in the
case of a corporation, executed under its common seal or signed on its behalf by an attorney or a duly authorised officer of the corporation and delivered to the Agent not later than 48 hours before the time fixed for any meeting, appoint any person
(a proxy) to act on his or its behalf in connection with any meeting or proposed meeting of Bondholders. 

  

	3.	A holder of a Bond which is a corporation may by delivering to any Agent not later than 48 hours before the time fixed for any meeting a resolution of its directors or other
governing body in English authorise any person to act as its representative (a representative) in connection with any meeting or proposed meeting of Bondholders. 

  

	4.	A proxy or representative so appointed shall so long as such appointment remains in force be deemed, for all purposes in connection with any meeting or proposed meeting of
Bondholders specified in such appointment, to be the holder of the Bonds to which such appointment relates and the holder of the Bond shall be deemed for such purposes not to be the holder. 

  

	5.	Each of the Issuer and the Trustee may at any time convene a meeting of Bondholders. If the Trustee receives a written request by Bondholders holding at least 10 per cent. in
principal amount of the Bonds for the time being outstanding and is indemnified to its satisfaction against all costs and expenses, the Trustee shall convene a meeting of Bondholders. Every meeting shall be held at a time and place approved by the
Trustee. 

  

	6.	At least 14 business days’ (as defined in Clause 21) notice (exclusive of the day on which the notice is given and of the day of the meeting) shall be given to the Bondholders
to convene a meeting of Bondholders. A copy of the notice shall be given by the party convening the meeting to the other parties. The notice shall specify the day, time and place of meeting, be given in the manner provided in the Conditions and
shall specify, unless the Trustee otherwise agrees, the nature of the resolutions to be proposed and shall include a statement to the effect that the holders of Bonds may appoint proxies by executing and delivering a form of proxy in English to the
specified office of an Agent not later than 48 hours before the time fixed for the meeting or, in the case of corporations, may appoint representatives by resolution in English of their directors or other governing body and by delivering an executed
copy of such resolution to the Agent not later than 48 hours before the time fixed for the meeting. 

  

	7.	A person (who may, but need not, be a Bondholder) nominated in writing by the Trustee may act as chairman of a meeting but if no such nomination is made or if the person nominated
is not present within 15 minutes after the time fixed for the meeting the Bondholders present shall choose one of their number to be chairman, failing which, the Issuer may appoint the chairman. The chairman of an adjourned meeting need not be the
same person as was chairman of the original meeting. 

  

	8.	 At a meeting one or more persons present in person holding Bonds or being proxies or representatives and holding or representing in the aggregate not less than
10 per cent. in principal amount of the Bonds for the time being outstanding shall (except for the purpose of passing an Extraordinary Resolution) form a quorum for the transaction of business and no business (other than the choosing of a
chairman) shall be transacted unless the requisite quorum be present at the commencement of business. The quorum at a meeting for passing an Extraordinary Resolution shall (subject as provided below) be one or more persons present in person holding
Bonds or being proxies or representatives and holding or representing in the aggregate over 50 per cent. in principal amount of the Bonds for the time being outstanding provided that the quorum at any meeting the 

  

 154 

	 	 
business of which includes any of the matters specified in the proviso to paragraph 18 shall be two or more persons so present holding Bonds or being proxies
or representatives and holding or representing in the aggregate not less than 66 per cent, in principal amount of the Bonds for the time being outstanding. 

  

	9.	If within 15 minutes from the time fixed for a meeting a quorum is not present the meeting shall, if convened upon the requisition of Bondholders or if the Issuer and the Trustee
agree, be dissolved. In any other case it shall stand adjourned to such date, not less than 14 nor more than 42 days later, and to such place as the chairman may decide. At such adjourned meeting one or more persons present in person holding Bonds
or being proxies or representatives (whatever the principal amount of the Bonds so held or represented) shall form a quorum and may pass any resolution and decide upon all matters which could properly have been dealt with at the meeting from which
the adjournment took place had a quorum been present at such meeting provided that at any adjourned meeting at which is to be proposed an Extraordinary Resolution for the purpose of effecting any of the modifications specified in the proviso to
paragraph the quorum shall be one or more persons so present holding Bonds or being proxies or representatives and holding or representing in the aggregate not less than 33 per cent, in principal amount of the Bonds for the time being
outstanding. 

  

	10.	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 but no business shall be transacted at an
adjourned meeting which might not lawfully have been transacted at the meeting from which the adjournment took place. 

  

	11.	At least 10 days’ notice of any meeting adjourned through want of a quorum shall be given in the same manner as for an original meeting and such notice shall state the quorum
required at the adjourned meeting. No notice need, however, otherwise be given of an adjourned meeting. 

  

	12.	Each question submitted to a meeting shall be decided in the first instance by a show of hands and 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 the vote or votes (if any) which he may have as a Bondholder or as a holder of a voting certificate or as a proxy or representative. 

  

	13.	Unless a poll is (before or on the declaration of the result of the show of hands) demanded at a meeting by the chairman, the Issuer, the Trustee or by one or more persons holding
one or more Bonds or being proxies or representatives and holding or representing in the aggregate not less than two per cent, in principal amount of the Bonds for the time being outstanding, a declaration by the chairman that a resolution has been
carried or carried by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact without proof of the number or proportion of the votes recorded in favour of or against such resolution.

  

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

  

	15.	A poll demanded on the election of a chairman or on any question of adjournment shall be taken at the meeting without adjournment. 

  

	16.	The Issuer and the Trustee (through their respective representatives) and their respective financial and legal advisers may attend and speak at any meeting of Bondholders. No one
else may attend or speak at a meeting of Bondholders unless he is the holder of a Bond or is a proxy or a representative. 

  

 155 

	17.	On a show of hands every holder who is present in person or any person who is present and is a proxy or a representative shall have one vote and on a poll every person who is so
present shall have one vote in respect of each U.S.$100,000 in principal amount of the Bonds produced or in respect of which he is a proxy or a 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.	A proxy need not be a Bondholder. 

  

	19.	A meeting of Bondholders shall, subject to the Conditions, in addition to the powers given above, but without prejudice to any powers conferred on other persons by this Trust Deed,
have power exercisable by Extraordinary Resolution: 

  

	 	19.1	to sanction any proposal by the Issuer for any modification, abrogation, variation or compromise of, or arrangement in respect of, the rights of the Bondholders against the Issuer
and/or the Security for the Bonds whether or not such rights arise under this Trust Deed and/or the Security Documents; 

  

	 	19.2	to sanction the exchange or substitution for the Bonds of, or the conversion of the Bonds into, shares, bonds, or other obligations or securities of the Issuer or any other entity,

  

	 	19.3	to assent to any modification of this Trust Deed, the Security Documents or the Bonds or the Security which shall be proposed by the Issuer or the Trustee; 

 

	 	19.4	to authorise anyone to concur in and do anything necessary to carry out and give effect to an Extraordinary Resolution; 

  

	 	19.5	to give any authority, direction or sanction required to be given by Extraordinary Resolution; 

  

	 	19.6	to appoint any persons (whether Bondholders or not) as a committee or committees to represent the interests of the Bondholders and to confer on them any powers or discretions which
the Bondholders could themselves exercise by Extraordinary Resolution; 

  

	 	19.7	to approve the substitution of any entity for the Issuer (or any previous substitute) as principal debtor under this Trust Deed; 

  

	 	19.8	to approve a proposed new Trustee and to remove a Trustee; and 

  

	 	19.9	to discharge or exonerate the Trustee from any liability in respect of any act or omission for which it may become responsible under this Trust Deed or the Bonds,

 provided that the special quorum provisions contained in the proviso to paragraph 8 and, in the case of an adjourned
meeting, in the proviso to paragraph 9 shall apply for the purpose of making any modification to the provisions contained in this Trust Deed or the Bonds which would have the effect of: 
  

	 	18.9.1	modifying the due date for any payment in respect of the Bonds; or 

  

	 	18.9.2	reducing or cancelling the amount of principal, premium or interest or Equivalent Amount payable in respect of the Bonds; or 

  

	 	18.9.3	changing the currency of payment of the Bonds; or 

  

	 	18.9.4	modifying or cancelling the Conversion Rights or the security constituted by the Security Documents; or 

  

 156 

	 	18.9.5	modifying the provisions contained in this Schedule concerning the quorum required at a meeting of Bondholders or the majority required to pass an Extraordinary Resolution or sign a
resolution in writing; or 

  

	 	18.9.6	amending this proviso. 

  

	20.	An Extraordinary Resolution passed at a meeting of Bondholders duly convened and held in accordance with this Trust Deed 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 of such resolution justify the passing of it. 

  

	 21.
	 The expression Extraordinary Resolution means a resolution passed at a meeting of Bondholders duly convened and
held in accordance with these provisions by a majority consisting of not less than 66 2/3 per cent. in principal amount of
the Bonds for the time being outstanding. 

  

	 22.
	 A resolution in writing signed by or on behalf of the holders of not less than 66 2/3 per cent. in principal amount of the Bonds who for the time being are entitled to receive notice of a meeting in accordance with
these provisions shall for all purposes be as valid as an Extraordinary Resolution passed at a meeting of Bondholders convened and held in accordance with these provisions. Such resolution in writing may be in one document or several documents in
like form each signed by or on behalf of one or more of the Bondholders. 

  

	23.	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 of
Bondholders, 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. 

  

	24.	If and whenever the Issuer has issued and has outstanding Bonds of more than one tranches the foregoing provisions of this Schedule shall have effect subject to the following
modifications: 

  

	 	24.1	a resolution which in the opinion of the Trustee affects Bonds of only one tranche shall be deemed to have been duly passed if passed at a separate meeting of the holders of the
Bonds of that tranche; 

  

	 	24.2	a resolution which in the opinion of the Trustee affects the Bonds of more than one tranches but does not give rise to a conflict of interest between the holders of Bonds of any of
the tranches so affected shall be deemed to have been duly passed if passed at a single meeting of the holders of the Bonds of all the tranches so affected; 

  

	 	24.3	a resolution which in the opinion of the Trustee affects the Bonds of more than one tranches and gives or may give rise to a conflict of interest between the holders of the Bonds of
one tranche or group of tranches so affected and the holders of the Bonds of another tranche or group of tranches so affected shall be deemed to have been duly passed only if passed at separate meetings of the holders of the Bonds of each tranche or
group of tranches so affected; and 

  

	 	24.4	to all such meetings all the preceding provisions of this Schedule shall mutatis mutandis apply as though references therein to Bonds and holders were references to the Bonds
of the tranche or group of tranches in question or to the holders of such Bonds, as the case maybe. 

  

	25.	 Subject to all other provisions contained in this Trust Deed the Trustee may without the consent of the Bondholders prescribe such further regulations regarding the
holding of meetings and attendance and voting at them or regarding the making of 

  

 157 

	 	 
resolutions in writing as the Trustee may in its sole discretion determine including (without limitation) such regulations and requirements as the Trustee
thinks reasonable to satisfy itself that persons who purport to make any requisition in accordance with this Trust Deed are entitled to do so and that those who purport to attend or vote at a meeting or to sign a written resolution are entitled to
do so.

Bonds due 2009 of the Issuer (the Tranche B Bonds, and together with the Tranche A Bonds, the Bonds, which expression where the context so admits shall include the Global Certificates (as defined below) to be delivered in respect of
them). The definitive Bonds, if required to be issued, will be in registered form in denominations of U.S.$100,000 each and integral multiples of U.S.$1,000 in excess thereof. Each Tranche B Bond will be convertible, subject as provided in the Terms
and Conditions of the Tranche B Bonds (the Tranche B Terms and Conditions) and upon the occurrence of a Complying IPO (as defined in the Tranche B Terms and Conditions), into fully paid ordinary shares of the Issuer (the Shares) in
accordance with the Tranche B Terms and Conditions. The Bonds will be secured by way of (a) a charge over the assets of the Issuer pursuant to a Security Agreement expected to be dated the Closing Date (as defined below) between DB Trustees
(Hong Kong) Limited as security agent (the Security Agent) and the Issuer (the Security Agreement); (b) a mortgage of shares in Asia Silicon Technology Holdings Limited (AST (HK)) owned by the Issuer pursuant to a Share
Mortgage expected to be dated the Closing Date (as defined below) between the Security Agent and the Issuer (the Share Mortgage); (c) a charge over the assets of AST (HK) pursuant to a Security Agreement expected to be dated the Closing
Date (as defined below) between the Security Agent and AST (HK) (the Security Agreement (AST (HK)) and (d) a pledge of equity interest of AST (HK) in Opco on the Closing Date pursuant to a Pledge of Equity expected to be dated the
Closing Date (as defined below) between the Security Agent and AST (HK) (the First Pledge of Equity) and (e) a pledge of equity interest of AST (HK) in Opco acquired as a result of an increase in the registered capital of Opco after the
Closing Date pursuant to a Pledge of Equity to be entered into between the Security Agent and AST (HK) (the Second Pledge of Equity), each in favour of the Security Agent for the benefit of the holders of the Bonds (each security being
created thereby being referred to as a Security). In this Agreement, each of the Security Agreement, the Share Mortgage, the Security Agreement (AST (HK)), the First Pledge of Equity and the Second Pledge of Equity is called a Security
Document and together are called the Security Documents.

 2

 The Issuer
represents and warrants to the Manager that as at the date of this Agreement and as at the Closing Date (and at any time from the date hereof up to and including the Closing Date): 
  

	 	(a)	No default 

 No event has occurred or circumstance arisen

Conditions; 
  

	 	(b)	Directed selling efforts 

 Neither the Issuer nor its
affiliates (as defined in Rule 405 under the United States Securities Act of 1933, as amended (the Securities Act)), nor any persons acting on its or their behalf have engaged or will engage in any directed selling efforts (as defined in
Regulation S of the Securities Act) with respect to the Bonds; 
  

	 	(c)	Foreign issuer; SUSMI

the Tranche B Bonds or any securities of the same class as the Shares issuable upon conversion of the Tranche B Bonds; and 
  

	 	(d)	Section 3(a)9 Compliance 

 In connection with the
conversion of the Tranche B Bonds into the Shares neither the Issuer nor any person acting on its behalf will take any action which would result in the shares issuable upon conversion of the Tranche B Bonds being exchanged by the Issuer other than
with the Issuer’s existing security holders exclusively where no commission or remuneration is paid or given directly or indirectly for soliciting such exchange. 
  

	5.	UNDERTAKINGS BY THE ISSUER

	5.5	Restrictions on other issues

	1.	Status and Security 

  

	1.1	Subject as provided in this Condition 1 and Condition 6, the Bonds constitute direct, unsubordinated, unconditional and secured obligations of the Issuer and shall at all times rank
pari passu without any preference or priority among themselves. 

  

	1.2	 The Issuer has credited to an account (the Interest Reserve Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly
described in the Issuer Security Agreement the sum of U.S.$4,200,000 out of the proceeds of the issue of the Bonds and the Tranche B Bonds. Pursuant to the Issuer Security Agreement, the Interest Reserve Account is 

  

 15 

	 	 
charged to the Security Agent as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) to the Secured Parties
under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Pursuant to the Issuer Security Agreement, such moneys, once deposited, may only be withdrawn from the Interest Reserve Account by the Issuer and released from the
security constituted by the Issuer Security Agreement in accordance with the Issuer Security Agreement. If and to the extent that such moneys are not released from the Interest Reserve Account as aforesaid by the Maturity Date (as defined in
Condition 10.1), the Bondholders shall have the right to require such moneys to be applied in redeeming their Bonds pursuant to Condition 10. 

  

	1.3	The Issuer has credited to an account (the Escrow Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the Issuer
Security Agreement the remainder of the proceeds of the issue of the Bonds and the Tranche B Bonds (after deducting the funds credited into the Interest Reserve Account). Pursuant to the Issuer Security Agreement, the Escrow Account is charged to
the Security Agent as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Such moneys may only be withdrawn from
the Escrow Account for the purposes set out in Condition 6.21(a)(ii) to 6.21(a)(v) and in accordance with the procedures set forth in the Issuer Security Agreement and subject to all of the conditions set forth in the Issuer Security Agreement being
satisfied, provided that if and to the extent that such moneys standing to the credit of the Escrow Account are not so released from the Escrow Account by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to
require such moneys to be applied in redeeming their Bonds pursuant to Condition 10. 

  

	1.4	The Bonds will have the benefit of the Security (as defined in Condition 1.5) as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK)
to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. On the Issue Date, the Issuer will (simultaneously with the issue of the Bonds) issue the Tranche B Bonds (as defined in the Trust Deed). The
Tranche B Bonds will have the benefit of the same security as the Bonds, and the payment obligations of the Issuer under the Bonds shall at all times rank at least equally with its payment obligations under the Tranche B Bonds. The Security Agent or
its nominee will hold the Security for the benefit of the Bondholders and the holders of the Tranche B Bonds pursuant to the provisions of the Trust Deed. 

  

	1.5	The security constituted by the Security Documents (the Security) shall become immediately enforceable if an Event of Default occurs, following which the Security Agent may,
but shall not be bound (except as provided in Condition 15 and provided it has been indemnified and/or secured to its satisfaction) to take such proceedings or other action as it shall, in its discretion, think fit to enforce the Security (or any
part thereof) and the provisions of the Trust Deed and the Security Documents. The Trust Deed and the Security Documents provide that the net proceeds resulting from the enforcement of the Security, after the remuneration of the Trustee and/or any
Appointee, the Security Agent and any Receiver, and the Agents and all their respective costs, charges, liabilities and expenses and any taxes and other amounts required to be paid prior to any such application, be applied pro rata in meeting claims
of any Bondholders or holders in respect of the Tranche B Bonds whose Bonds or, as the case may be, Tranche B Bonds are then outstanding. 

  

	2.	Form and Denomination 

 The Bonds are issued in
registered form in the denomination of U.S.$100,000 each and integral multiples of U.S.$1,000 (referred to as the principal amount of a Bond) in excess thereof (the authorised denomination). A Bond certificate (each a

	(b)	The rate of interest payable from time to time in respect of the Bonds (the Rate of Interest) will be determined on the basis of the following provisions:

  

	 	(i)	on each Interest Determination Date (as defined below), the Principal Agent or its duly appointed successor will determine the Screen Rate (as defined below) at approximately 11.00
a.m. (London time) on that Interest Determination Date. If the Screen Rate is unavailable, the Principal Agent will request the principal London office of each of the Reference Banks (as defined below) to provide the Principal Agent with the rate at
which deposits in U.S. dollars are offered by it to prime banks in the London interbank market for three months at approximately 11.00 a.m. (London time) on the Interest Determination Date in question and for a Representative Amount (as defined
below); 

  

	 	(ii)	the Rate of Interest for the relevant Interest Period shall be the Screen Rate plus the Margin (as defined below) or, if the Screen Rate is unavailable, and if at least two of the
Reference Banks which have been requested by the Principal Agent to provide such rates, provide such rates, the arithmetic mean (rounded if necessary to the fifth decimal place, with 0.000005 being rounded upwards) as established by the Principal
Agent of such rates, plus the Margin; 

  

	 	(iii)	if fewer than two rates are provided as requested, the Rate of Interest for that Interest Period will be the arithmetic mean of the rates quoted by major banks in London selected by
the Principal Agent, at approximately 11.00 a.m. (London time) on the relevant Interest Determination Date for loans in U.S. dollars to prime banks in London for a period of three months commencing on the first day of such Interest Period and for a
Representative Amount, plus the Margin. If the Rate of Interest cannot be determined in accordance with the above provisions, the Rate of Interest shall be determined as at the last preceding Interest Determination Date. 

  

	 	(iv)	The Margin (the Margin) is (A) 3 per cent. per annum for the period from and including the Issue Date up to but excluding the Margin Step-up Date; and
(B) 5 per cent. per annum from and including the Margin Step-up Date. 

  

	 	(v)	In this Condition 7, (except where otherwise defined), the expression: 

  

	 	(A)	Business Day means, in relation to any place, a day (other than a Saturday or Sunday) which is a day on which commercial banks and foreign exchange markets settle payments
and are open for general business (including dealing in foreign exchange and foreign currency deposits) in such place; 

  

	 	(B)	Interest Determination Date means the second Business Day in London before the commencement of the Interest Period for which the rate will apply; 

  

	 	(C)	Margin Step-up Date means the date falling 12 months from the Issue Date; 

  

	 	(D)	Reference Banks means the principal London office of each of four major banks engaged in the London interbank market selected by the Payment Agent; 

 

	 	(E)	Representative Amount means, in relation to any quotation of a rate for which a Representative Amount is relevant, an amount that is representative for a single transaction
in the relevant market at 11 :00 a.m. (local time); and 

  

	 	(F)	Screen Rate means the rate for three month deposits in U.S. dollars which appears on the display designated as LIBOR0l on Reuters (or such replacement page on that service
which displays the information, or such other service as may be nominated as the information vendor, for the purposes of displaying rates or prices comparable to that rate). 

  

 45 

	7.2	Determination of Interest Amount 

 The
Principal Agent will, as soon as practicable after 11.00 a.m. (London time) on each Interest Determination Date, but in no event later than the third Business Day in Hong Kong thereafter, determine the U.S. dollar amount (the Interest Amount)
payable in respect of interest on the principal amount of each Bond for the relevant Interest Period. The Interest Amount shall be determined by applying the Rate of Interest to the principal amount of a Bond, multiplying the sum by the actual
number of days in the Interest Period concerned divided by 360 and rounding the resultant figure to the nearest cent (half a cent being rounded upwards). 
  

	7.3	Publication of Rate of Interest and Interest Amount 

 The Principal Agent shall cause the Rate of Interest and the Interest Amount for each Interest Period and the Interest Payment Date relating to such Interest Period to be notified to the Issuer, the Trustee (by no later than the first day
of each Interest Period) and to be published in accordance with Condition 19 as soon as possible after their determination, and in no event later than the second Business Day in Hong Kong thereafter. The Interest Amount and Interest Payment Date may
subsequently be amended (or appropriate alternative arrangements made by way of adjustment) without notice to the Bondholders in the event of an extension or shortening of the Interest Period. 
  

	7.4	Determination by the Trustee 

 If the
Principal Agent defaults at any time in its obligation to determine the Rate of Interest and Interest Amount in accordance with the above provisions, the Trustee shall determine (a) the Rate of Interest at such rate as, in its absolute
discretion (having such regard as it shall think fit to the procedure described above), it shall deem fair and reasonable in all the circumstances and (b) the Interest Amount in the manner provided in Condition 7.2 above, and all such
determinations shall be deemed to be determinations by the Principal Agent. 
  

	7.5	Notifications, etc. to be Final 

 All
notifications, opinions, determinations, certificates, calculations, quotations and decisions given, expressed, made or obtained for the purposes of the provisions of this Condition 7, whether by the Reference Banks (or any of them), the Principal
Agent or the Trustee, will (in the absence of wilful default, bad faith or manifest error) be binding on the Issuer, the Trustee, the Agents and all Bondholders and (in the absence of wilful default, bad faith or manifest error) no liability to the
Issuer or the Bondholders shall attach to the Reference Banks (or any of them), the Principal Agent or, if applicable, the Trustee in connection with the exercise or non-exercise by any of them of their powers, duties and discretions under this
Condition 7. 
  

	7.6	Principal Agent 

 The Issuer shall procure
that, so long as any of the Bonds remains outstanding, there is at all times a Principal Agent for the purposes of the Bonds and the Issuer may, subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld,
delayed or refused), terminate the appointment of the Principal Agent. In the event of the appointed office of any bank being unable or unwilling to continue to act as the Principal Agent or failing duly to determine the Rate of Interest or the
Interest Amount for any Interest Period, the Issuer shall, subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld, delayed or refused), appoint the London office of another major bank engaged in the
London interbank market to act in its place. The Principal Agent may not resign its duties or be removed without a successor having been appointed. 
  

 46 

	7.7	Interest Accrual 

  

	(a)	Each Bond will cease to bear interest (but without prejudice to the obligation of the Issuer to pay any accrued but unpaid interest), and shall be payable, (i) where a
Complying IPO shall have occurred, from, and including, the IPO Date, or (ii) from, and including, the due date for redemption thereof unless, upon due presentation of the relevant Bond payment of principal and/or premium (if any) is improperly
withheld or refused or unless default is otherwise made in respect of payment. In such event such Bond shall continue to bear interest as provided in the Trust Deed. 

  

	(b)	If interest is required to be calculated for a period of less than one year (other than a full semi-annual period), it will be calculated on the basis of a 360-day year consisting
of 12 months of 30 days each and, in the case of an incomplete month, the number of days elapsed. 

  

	8.	[Intentionally omitted]

	9.4	Payment Initiation 

 Where payment is to be
made by transfer to a registered account, payment instructions (for value on the due date or, if that is not a business day (as defined below), for value on the first following day which is a business day) will be initiated and, 

  

 47 

 
where payment is to be made by cheque, the cheque will be mailed (at the risk and, if mailed at the request of the holder otherwise than by ordinary mail,
expense of the holder) on the due date for payment (or, if it is not a business day, the immediately following business day) or, in the case of a payment of principal, premium (if any) or a payment of interest due otherwise than on an Interest
Payment Date, if later, on the business day on which the relevant Certificate is surrendered at the specified office of an Agent. 
  

	9.5	Delay In Payment 

 Bondholders will not be
entitled to any interest or other payment for any delay after the due date in receiving the amount due if the due date is not a business day, if the Bondholder is late in surrendering its Certificate (if required to do so) or if a cheque mailed in

Bondholders, fractions of one U.S. cent will be rounded down to the nearest U.S. cent. 
  

	10.	Redemption, Purchase and Cancellation 

  

	10.1	Maturity 

  

	(a)	Subject to paragraph (b) below, unless previously redeemed or purchased and cancelled as provided herein, the Issuer will on the date falling 24 months from the Issue Date (the
Maturity Date) redeem each Bond at 125 per cent. of its principal amount. The Issuer may not redeem the Bonds at its option prior to the Maturity Date except as provided in Condition 10.2 and Condition 10.3(but in each case without
prejudice to Condition 11). 

  

	(b)	Paragraph (a) above does not apply where the IPO Date (as defined in the Tranche B Conditions) falls on the Maturity Date, in which case Condition 10.3(a) will apply.

  

	10.2	Redemption for Taxation Reasons 

  

	(a)	 At any time the Issuer may, having given not less than 30 nor more than 60 days’ notice (a Tax Redemption Notice) to the Bondholders in accordance with
Condition 19 (which notice shall be irrevocable) redeem all, and not some only, of the Bonds at a redemption price equal to 125 per cent. of their principal amount, together with any accrued interest and Break Cost (if any), on the redemption
date specified in the Tax Redemption Notice (the Tax Redemption Date) if (i) the Issuer satisfies the Trustee immediately prior to the giving of such Tax Redemption Notice that the Issuer has or will become obliged to pay additional
amounts as referred to in Condition 11 as a result of any change in, or amendment to, the laws or regulations of the relevant jurisdiction, or any change in the general application or official interpretation of such laws or regulations, which

  

 48 

	 	 
change or amendment becomes effective on or after the Issue Date, and (ii) such obligation cannot be avoided by the Issuer taking reasonable measures
available to it, provided that no Tax Redemption Notice shall be given earlier than 90 days prior to the earliest date on which the Issuer would be obliged to pay such additional amounts were a payment in respect of the Bonds then due. Prior to the
publication of any Tax Redemption Notice pursuant to this paragraph, the Issuer shall deliver to the Trustee (A) an Officer’s Certificate stating that the obligation referred to in (i) above cannot be avoided by the Issuer taking
reasonable measures available to it and (B) an opinion of independent legal or tax advisors of recognised standing to the effect that such change or amendment has occurred or will occur (irrespective of whether such amendment or change is then
effective) and the Trustee shall be entitled without further enquiry to accept such certificate and opinion as sufficient evidence thereof in which event it shall be conclusive and binding on the Bondholders. 

  

	(b)	If the Issuer gives a Tax Redemption Notice pursuant to Condition 10.2(a), each Bondholder will have the right to elect that its Bond(s) shall not be redeemed and that the
provisions of Condition 11 shall not apply in respect of any payment of principal, premium (if any) or interest to be made in respect of such Bond(s) which falls due after the relevant Tax Redemption Date whereupon no additional amounts shall be
payable in respect thereof pursuant to Condition 11 and payment of all amounts shall be made subject to the deduction or withholding of any tax required to be deducted or withheld (provided that such election shall only be in respect of the
deduction or withholding then required to be made and the Issuer shall comply with the provisions of Condition 11 in respect of any further deductions or withholding). To exercise a right pursuant to this Condition 10.2, the holder of the relevant
Bond must complete, sign and deposit at the specified office of any Paying Agent a duly completed and signed notice of exercise, in the form for the time being current, obtainable from the specified office of any Paying Agent together with the
Certificate evidencing the Bonds on or before the day falling 10 days prior to the Tax Redemption Date.

	(a)	At the same time as the Issuer issues the IPO Certificate (as defined in the Tranche B Conditions) under the Tranche B Conditions, the Issuer shall cause a copy of the IPO
Certificate (as defined in the Tranche B Conditions) to be given to the Bondholders in accordance with the provisions of Condition 19. On the IPO Date (as defined in the Tranche B Conditions), the Issuer shall redeem all of the outstanding Bonds at
100 per cent. of their principal amount together with interest accrued to (but excluding) the date of redemption and Break Cost (if any). 

  

	(b)	The Issuer shall forthwith and in any event not later than 15 business days’ prior to any Strategic Sale (as defined in Condition 6.28) give notice to the Bondholders of the
Strategic Sale. The notice shall specify the date of the Strategic Sale, the shares to be transferred, the terms of the proposed Strategic Sale, the parties involved and the consideration. The Issuer shall on the date of the completion of the
Strategic Sale redeem all of the outstanding Bonds at 125 per cent. of their principal amount, together with interest accrued to (but excluding) the date of redemption and Break Cost (if any).

without deduction or withholding for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature, unless deduction or withholding of such taxes, duties, assessments or governmental charges is
compelled by law. In such event, the Issuer will pay such additional amounts as will result in the receipt by the Bondholders and other Finance Parties of the net amounts after such deduction or withholding equal to the amounts which would otherwise
have been receivable by them had no such deduction or withholding been required except that no such additional amount shall be payable in respect of any Bond: 

  

	 	(i)	to a holder (or to a third party on behalf of a holder) who is subject to such taxes, duties, assessments or governmental charges in respect of such Bond by reason of his having
some connection with the Cayman Islands or such other jurisdiction otherwise than merely by holding the Bond or by the receipt of amounts in respect of the Bond; 

  

	 	(ii)	(in the case of a payment of principal) if the Certificate in respect of such Bond is surrendered more than 30 days after the relevant date except to the extent that the holder
would have been entitled to such additional amount on surrendering the relevant Certificate for payment on the last day of such period of 30 days; 

  

	 	(iii)	where such withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to European Council Directive 2003/48/EC or any law implementing or
complying with, or introduced in order to conform to, such Directive; or 

  

	 	(iv)	presented for payment by or on behalf of a Bondholder who would have been able to avoid such withholding or deduction by presenting the relevant Bond to another Paying Agent in a
Member State of the European Union. 

 For the purposes this paragraph (a): 
 relevant date means whichever is the later of (a) the date on which such payment first becomes due and (b) if the full amount payable has
not been received by the Trustee or the Principal Agent on or prior to such due date, the date on which, the full amount having been so received, notice to that effect shall have been given to the Bondholders and cheques despatched or payment made.

 References in these Conditions to principal, premium (if any) and interest, and any other amounts to be paid by the Issuer under the Bonds,
shall be deemed also to refer to any additional amounts which may be payable under this Condition or any undertaking or covenant given in addition thereto or in substitution therefor pursuant to the Trust Deed. 
  

	(b)	If the Issuer makes a Tax Payment and a Bondholder (in its absolute discretion) determines that: 

  

	 	(i)	a Tax Credit is attributable to that Tax Payment; and 

  

 50 

	 	(ii)	it has used and retained that Tax Credit, 

 the relevant
Bondholder must pay an amount to the Issuer which that Bondholder determines (in its absolute discretion) will leave it (after that payment) in the same after-tax position as it would have been if the Tax Payment had not been required to be made by
the Issuer. 
 For the purpose of this paragraph (b): 
 Tax means any tax, levy, impost, duty or other charge or withholding of a similar nature (including any related penalty or interest); 
 Tax Credit means a credit against any Tax or any relief or remission for Tax (or its repayment); 
 Tax Deduction means a deduction or withholding for or on account of Tax from a payment under any Finance Document; and

accordingly thereby become, immediately due and repayable at 125 per cent. of their principal amount together with any accrued and unpaid interest and Break Costs (if any) if any of the following events is subsisting at the time of the notice:

 55 

	15.2	Modification and Waiver

any such consent as aforesaid, that any Event of Default or Potential Event of Default (as defined in the Trust Deed) shall not be treated as such (provided that, in any such case, it is not, in the opinion of the Trustee, materially prejudicial to
the interests of the Bondholders). Any such modification, waiver, authorisation or determination will be binding on the Bondholders and, unless the Trustee agrees otherwise, any such modifications will be notified by the Issuer to the Bondholders as
soon as practicable thereafter.

Bondholders and in any event not less than 45 days’ notice will be given. 
  

 56

validly given if mailed to them at their respective addresses in the Register of Bondholders maintained by the Registrar or published in a leading newspaper having general circulation in Hong Kong or, if such publication shall not be practicable, in

 PART 2 
 TRANCHE B TERMS AND CONDITIONS 
 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 will appear on the reverse of each of the Certificates

 The issue of the Tranche B U.S.$40,000,000 aggregate principal amount of Floating Rate Secured Convertible Bonds due 2009 (the
Bonds) of Asia Silicon Technology Holdings Inc. (the Issuer), and the creation of the Security (as defined in Condition 1.5), was authorised by a resolution of the board of directors of the Issuer passed on 5 September 2007. The
Bonds are constituted by a trust deed dated 10 September 2007 (the Trust Deed) made between the Issuer, DB Trustees (Hong Kong) Limited as trustee for the holders of the Bonds (the Trustee, which term shall, where the context so
permits, include all other persons or companies for the time being acting as trustee or trustees under the Trust Deed) and DB Trustees (Hong Kong) Limited as security agent for the Secured Parties (the Security Agent) and are subject to the
paying and conversion agency agreement dated 10 September 2007 (the Agency Agreement) entered into between the Issuer, the Trustee, Deutsche Bank AG, Hong Kong Branch as principal paying, conversion and transfer agent (the Principal
Agent) and Deutsche Bank Luxembourg S.A. as registrar (the Registrar) and the other paying, conversion and transfer agents appointed under it (each a Paying Agent, Conversion Agent, Transfer Agent and together with the Registrar
and the Principal Agent, the Agents) relating to the Bonds. References to the Principal Agent, Registrar and Agents below are references to the principal agent, registrar and agents for the time being for the Bonds. The
statements in these terms and conditions of the Bonds (these Conditions) include summaries of, and are subject to, the detailed provisions of the Trust Deed and the Agency Agreement. Unless otherwise defined, terms used in these Conditions
have the meanings specified in the Trust Deed, the Security Agreement dated 10 September 2007 (the Issuer Security Agreement) between the Issuer and the Security Agent and the other Finance Documents (as defined in the Trust Deed) other
than the Subscription Agreement. Copies of the Trust Deed, the Agency Agreement, the Issuer Security Agreement and the other Finance Documents are available for inspection during normal business hours at the registered office of the Trustee being as
at the date hereof at 55th Floor, Cheung Kong Center, 2 Queen’s Road Central, Hong Kong and at the specified offices of each of the Agents. The Bondholders are bound by, and are deemed to have notice of, all the provisions of the Trust Deed,
the Agency Agreement, the Issuer Security Agreement and the other Finance Documents applicable to them. 
 The owners shown in the records of Euroclear
Bank, S.A./N.V., as operator of the Euroclear System (Euroclear), Clearstream Banking, société anonyme (Clearstream, Luxembourg) of book-entry interests in Bonds are entitled to the benefit of
and are bound by, and are deemed to have notice of, all the provisions of the Trust Deed and the Agency Agreement applicable to them. 
  

	1.	Status and Security 

  

	1.1	Subject as provided in this Condition 1 and Condition 6, the Bonds constitute direct, unsubordinated, unconditional and secured obligations of the Issuer and shall at all times rank
pari passu without any preference or priority among themselves. 

  

	1.2	The Issuer has credited to an account (the Interest Reserve Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the
Issuer Security Agreement the sum of U.S.$4,200,000 out of the proceeds of the issue of the Bonds and the Tranche A Bonds. Pursuant to the Issuer Security Agreement, the Interest Reserve Account is charged to the Security Agent as security for all
amounts payable on the Bonds and all other moneys payable by the Issuer 

  

 60 

	 	 
or AST (HK) to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Pursuant to the Issuer Security
Agreement, such moneys, once deposited, may only be withdrawn from the Interest Reserve Account by the Issuer and released from the security constituted by the Issuer Security Agreement in accordance with the Issuer Security Agreement. If and to the
extent that such moneys are not released from the Interest Reserve Account as aforesaid by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to require such moneys to be applied in redeeming their Bonds pursuant
to Condition 10. 

  

	1.3	The Issuer has credited to an account (the Escrow Account) in the name of the Issuer with Deutsche Bank AG, Hong Kong Branch and more particularly described in the Issuer
Security Agreement the remainder of the proceeds of the issue of the Bonds and the Tranche A Bonds (after deducting the funds credited into the Interest Reserve Account). Pursuant to the Issuer Security Agreement, the Escrow Account is charged to
the Security Agent as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK) under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. Such moneys may only be withdrawn from
the Escrow Account for the purposes set out in Condition 6.21(a)(ii) to 6.21(a)(v) and in accordance with the procedures set forth in the Issuer Security Agreement and subject to all of the conditions set forth in the Issuer Security Agreement being
satisfied, provided that if and to the extent that such moneys standing to the credit of the Escrow Account are not so released from the Escrow Account by the Maturity Date (as defined in Condition 10.1), the Bondholders shall have the right to
require such moneys to be applied in redeeming their Bonds pursuant to Condition 10. 

  

	1.4	The Bonds will have the benefit of the Security (as defined in Condition 1.5) as security for all amounts payable on the Bonds and all other moneys payable by the Issuer or AST (HK)
to the Secured Parties under the Trust Deed, the Issuer Security Agreement and the other Finance Documents. On the Issue Date, the Issuer will (simultaneously with the issue of the Bonds) issue the Tranche A Bonds (as defined in the Trust Deed). The
Tranche A Bonds will have the benefit of the same security as the Bonds, and the payment obligations of the Issuer under the Bonds shall at all times rank at least equally with its payment obligations under the Tranche A Bonds. The Security Agent or
its nominee will hold the Security for the benefit of the Bondholders and the holders of the Tranche A Bonds pursuant to the provisions of the Trust Deed. 

  

	1.5	The security constituted by the Security Documents (the Security) shall become immediately enforceable if an Event of Default occurs, following which the Security Agent may,
but shall not be bound (except as provided in Condition 15 and provided it has been indemnified and/or secured to its satisfaction) to take such proceedings or other action as it shall, in its discretion, think fit to enforce the Security (or any
part thereof) and the provisions of the Trust Deed and the Security Documents. The Trust Deed and the Security Documents provide that the net proceeds resulting from the enforcement of the Security, after the remuneration of the Trustee and/or any
Appointee, the Security Agent and any Receiver, and the Agents and all their respective costs, charges, liabilities and expenses and any taxes and other amounts required to be paid prior to any such application, be applied pro rata in meeting claims
of any Bondholders or holders in respect of the Tranche A Bonds whose Bonds or, as the case may be, Tranche A Bonds are then outstanding. 

  

	2.	Form and Denomination 

  

	2.1	The Bonds are issued in registered form in the denomination of U.S.$100,000 each and integral multiples of U.S.$1,000 (referred to as the principal amount of a Bond) in
excess thereof (the authorised denomination). A Bond certificate (each a Certificate) will be issued to each Bondholder in respect of its registered holding of Bonds. Each Certificate will be numbered serially with an identifying
number which will be recorded on the relevant Certificate and in the Register (as defined in Condition 4.1) which the Issuer will procure to be kept by the Registrar. 

  

 61 

	2.2	Each Bond will entitle its registered holder, following the occurrence of a Complying IPO (as defined in Condition 8), to convert such Bond into Shares (as defined in Condition
8.l(d)) as described in Condition 8.

the Issuer, Mandra Materials Limited, Deutsche Bank AG and the Subsequent Shareholders named therein (the Registration Rights Agreement), the Issuer is required to effect registration in respect of the Shares under the
Securities Act (as defined in Condition 6.28) at the time and in a manner set out in the Registration Rights Agreement. The transferability of the Shares are subject to the restrictions set out in the Registration Rights Agreement and the Securities
Act. 
  

	3.	Title 

 Title to the Bonds passes only by
registration in the Register (as defined in Condition 4.1). The holder of any Bond will (except as otherwise required by law) be treated as its absolute owner for all purposes (whether or not it is overdue and regardless of any notice of ownership,
trust or any interest in it or any writing on, or the theft or loss of, the Certificate issued in respect of it) and no person will be liable for so treating the holder. In these Conditions Bondholder and (in relation to a Bond) holder
mean the person in whose name a Bond is registered.

	4.1	Register 

 The Issuer will cause to be kept
at the specified office outside the United Kingdom and Hong Kong of the Registrar and in accordance with the terms of the Agency Agreement a register on which shall be entered the names and addresses of the holders of the Bonds and the particulars

Registration Rights Agreement in respect of that Bond, and provided further that so long as no Event of Default is subsisting, a Bond may not be transferred, without the prior consent of the Issuer, to a person specified in a letter dated the Issue
Date addressed by the Issuer to, and accepted by, the Manager in respect of this Condition 4.2. A Bond may be transferred by delivery of the Certificate issued in respect of that Bond, with the form of transfer on the back duly completed and signed

transfer of Bonds will be effected without charge by or on behalf of the Issuer or any of the Agents, but upon payment (or the giving of such indemnity as the Issuer or any of the Agents may require) in respect of any taxes or other governmental

which deposits in U.S. dollars are offered by it to prime banks in the London interbank market for three months at approximately 11.00 a.m. (London time) on the Interest Determination Date in question and for a Representative Amount (as defined
below); 

  

	 	(ii)	the Rate of Interest for the relevant Interest Period shall be the Screen Rate plus the Margin (as defined below) or, if the Screen Rate is unavailable, and if at least two of the
Reference Banks which have been requested by the Principal Agent to provide such rates, provide such rates, the arithmetic mean (rounded if necessary to the fifth decimal place, with 0.000005 being rounded upwards) as established by the Principal
Agent of such rates, plus the Margin; 

  

	 	(iii)	if fewer than two rates are provided as requested, the Rate of Interest for that Interest Period will be the arithmetic mean of the rates quoted by major banks in London selected by
the Principal Agent, at approximately 11.00 a.m. (London time) on the relevant Interest Determination Date for loans in U.S. dollars to prime banks in London for a period of three months commencing on the first day of such Interest Period and for a
Representative Amount, plus the Margin. If the Rate of Interest cannot be determined in accordance with the above provisions, the Rate of Interest shall be determined as at the last preceding Interest Determination Date. 

  

	 	(iv)	The Margin (the Margin) is (A) 3 per cent. per annum for the period from and including the Issue Date up to but excluding the Margin Step-up Date; and

	7.2	Determination of Interest Amount 

 The
Principal Agent will, as soon as practicable after 11.00 a.m. (London time) on each Interest Determination Date, but in no event later than the third Business Day in Hong Kong thereafter, determine the U.S. dollar amount (the Interest Amount)
payable in respect of interest on the principal amount of each Bond for the relevant Interest Period. The Interest Amount shall be determined by applying the Rate of Interest to the principal amount of a Bond, multiplying the sum by the actual
number of days in the Interest Period concerned divided by 360 and rounding the resultant figure to the nearest cent (half a cent being rounded upwards). 
  

	7.3	Publication of Rate of Interest and Interest Amount 

 The Principal Agent shall cause the Rate of Interest and the Interest Amount for each Interest Period and the Interest Payment Date relating to such Interest Period to be notified to the Issuer, the Trustee (by no later than the first day

subsequently be amended (or appropriate alternative arrangements made by way of adjustment) without notice to the Bondholders in the event of an extension or shortening of the Interest Period. 
  

	7.4	Determination by the Trustee 

 If the
Principal Agent defaults at any time in its obligation to determine the Rate of Interest and Interest Amount in accordance with the above provisions, the Trustee shall determine (a) the Rate of Interest at such rate as, in its absolute
discretion (having such regard as it shall think fit to the procedure described above), it shall deem fair and reasonable in all the circumstances and (b) the Interest Amount in the manner provided in Condition 7.2 above, and all such
determinations shall be deemed to be determinations by the Principal Agent.

Agent or the Trustee, will (in the absence of wilful default, bad faith or manifest error) be binding on the Issuer, the Trustee, the Agents and all Bondholders and (in the absence of wilful default, bad faith or manifest error) no liability to the
Issuer or the Bondholders shall attach to the Reference Banks (or any of them), the Principal Agent or, if applicable, the Trustee in connection with the exercise or non-exercise by any of them of their powers, duties and discretions under this
Condition 7. 
  

	7.6	Principal Agent 

 The Issuer shall procure
that, so long as any of the Bonds remains outstanding, there is at all times a Principal Agent for the purposes of the Bonds and the Issuer may, subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld,
delayed or refused), terminate the appointment of the Principal Agent. In the event of the appointed office of any bank being unable or unwilling to continue to act as the Principal Agent or failing duly to determine the Rate of Interest or the
Interest Amount for any Interest Period, the Issuer shall, subject to the prior written approval of the Trustee (such approval not to be unreasonably withheld, delayed or refused), appoint the London office of another major bank engaged in the
London interbank market to act in its place. The Principal Agent may not resign its duties or be removed without a successor having been appointed. 
  

	7.7	Interest Accrual 

  

	(a)	Each Bond will cease to bear interest (but without prejudice to the obligation of the Issuer to pay any accrued but unpaid interest), and shall be payable, (i) where a
Complying IPO shall have occurred, from, and including, the IPO Date, or (ii) from, and including, the due date for redemption thereof unless, upon due presentation of the relevant Bond payment of principal and/or premium (if any) is improperly
withheld or refused or unless default is otherwise made in respect of payment. In such event such Bond shall continue to bear interest as provided in the Trust Deed. 

  

	(b)	If interest is required to be calculated for a period of less than one year (other than a full semi-annual period), it will be calculated on the basis of a 360-day year consisting
of 12 months of 30 days each and, in the case of an incomplete month, the number of days elapsed.

Complying IPO. 

 The right of a Bondholder to convert any Bond into Shares is called the Conversion Right.

	 	(i)	(A) during the period from (and including) the Issue Date to (but excluding) 1 October 2008, 2.732 % and (B) during the period from 1 October 2008 to the

	(c)	Strike Adjustment: If the Market Capitalisation at the Complying IPO is less than the Original Valuation, in addition to the Shares issued pursuant to paragraph
(a) above, the Issuer must, on the IPO Date, pay to the Bondholder of each Bond who has exercised the Conversion Right in relation to that Bond an amount calculated in accordance with this paragraph. The amount payable for each converted Bond
under this paragraph will be determined by the following formula:

	D	 	

  

 94

is the issue price per Share at the Complying IPO (or, if not in U.S. dollars, its equivalent in U.S. dollars as determined using a rate of exchange equal to the mid-exchange rate between the relevant currency and U.S. dollars quoted by Deutsche
Bank AG, Hong Kong Branch or failing which any other bank of international repute selected by the Trustee at 11:00 a.m. (Hong Kong time) on the date on which the IPO price is determined). 
 If the amount as determined by the formula above is not a whole U.S. dollar, it will be rounded up to the nearest whole U.S. dollar. 
  

	(d)	Conversion of more than one Bond: The Conversion Right may be 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. 

  

	(e)	Fractions of Shares: Fractions of Shares will not be issued on conversion and no cash adjustments will be made in respect thereof. 

  

	(f)	 Revival and/or survival after Default: Notwithstanding the provisions of Condition 8.2(a), if any Bond has become due and payable prior to the Maturity Date
by reason of the occurrence of any of the events under Condition 12, the Conversion Right attaching to such Bond will revive and/or will continue to be exercisable up to, and including, the close of business (at the place where the Certificate
evidencing such Bond is deposited for conversion) on the earlier of (i) the date upon which the full amount of the moneys payable in respect of such Bond has been duly received by the Principal Agent or the Trustee and notice of such receipt
has been duly given to the Bondholders and (ii) the date falling two business days prior to the Maturity Date and, notwithstanding the provisions of Condition 8.2(a), any Bond in respect of which the Certificate and Conversion Notice 

  

 95 

	 	 
(as defined in Condition 8.3) are deposited for conversion prior to such date shall be exchanged on the relevant Conversion Date (as defined in Condition
8.3(a)) notwithstanding that the full amount of the moneys payable in respect of such Bond shall have been received by the Principal Agent or the Trustee before such Conversion Date. 

  

	8.3	Conversion Procedure 

  

	(a)	Deemed exercise of Conversion Right: To elect not to exercise the Conversion Right attaching to any Bond, the holder thereof must complete, execute and deposit at its own
expense during business hours at the specified office of any Conversion Agent a notice of non-exercise (a Non-exercise Notice) in duplicate in the form (for the time being current) obtainable from the specified office of each Agent, during
the Conversion Period (as defined in Condition 8.2(a)). On the last day of the Conversion Period, in relation to any Bond, unless the holder thereof has elected not to exercise the Conversion Right attaching to that Bond under this paragraph (a),
that holder shall be deemed to have exercised its Conversion Rights in relation to that Bond. 

  

	(b)	Conversion Notice: Each Bondholder who is deemed under paragraph (a) above to have exercised its Conversion Right may complete, execute and deposit at its own expense
during business hours at the specified office of any Conversion Agent a notice specifying the name and address of the person in whose name the Shares issuable upon conversion are to be registered and giving other details in respect of the conversion
(a Conversion Notice) in duplicate in the form (for the time being current) obtainable from the specified office of each Agent not later than two business days prior to the Conversion Date. If a converting Bondholder fails to deliver a
Conversion Notice, the Bonds held by that Bondholder will nevertheless be converted in accordance with Condition 8.2(a). In that case the Shares will be issued in the name of that Bondholder and the certificate or certificates representing such
Shares shall be mailed to that Bondholder at its address specified in the Register. 

 The conversion date in respect of a Bond
(the Conversion Date) shall be the IPO Date. A Conversion Notice once delivered shall be irrevocable and may not be withdrawn unless the Issuer consents in writing to such withdrawal (and notified the Trustee and the Agents of such consent).

  

	(c)	Stamp Duty etc.: The Issuer must pay any taxes and capital, stamp, issue and registration duties arising on conversion (the Conversion Taxes) and the Issuer must also
pay all, if any, taxes arising by reference to any disposal or deemed disposal of a Bond in connection with such conversion and all other expenses arising on the issue of Shares on conversion. The Conversion Agent is under no obligation to determine
whether the Issuer is liable to pay any Conversion Taxes including capital, stamp, issue, registration or similar taxes and duties or the amounts payable (if any) in connection with this Condition 8.3(c). 

  

	(d)	 Registration: On the Conversion Date, the Issuer will, in the case of Bonds converted on exercise of the Conversion Right, register the person or persons
designated for the purpose in the Conversion Notice as holder(s) of the relevant number of Shares in the Issuer’s share register or, if no Conversion Notice is delivered, register the converting Bondholder as holders of the relevant number of
Shares in the Issuer’s share register and will, if the Bondholder has also requested in the Conversion Notice, take all necessary actions to procure that Shares are delivered through the relevant clearing and settlement system (if any) if and
for so long as the Shares are listed on a Stock Exchange; or will make the certificate or certificates representing such Shares available for collection at the office of the Issuer’s then share registrar notified to Bondholders in accordance
with Condition 19 or, if so requested in the relevant Conversion Notice, will cause its share registrar to mail (at the risk, and, if sent at the request of such person otherwise than by ordinary mail, at the expense, of the person to whom such
certificate or certificates are sent) such certificate or certificates to the person and at the place specified in the Conversion Notice, together (in either case) with any other securities, property or cash required to be delivered upon conversion
and such assignments and 

  

 96 

	 	 
other documents (if any) as may be required by law to effect the transfer thereof, in which case a single certificate will be issued in respect of all Shares
issued on conversion of Bonds subject to the same Conversion Notice and which are to be registered in the same name. 

 The
person or persons specified for that purpose 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 of the Bonds will in all respects rank pari passu with the Shares in issue on the relevant Registration Date. Save as set out in these Conditions, a holder of Shares issued on
conversion of Bonds shall not be entitled to any rights the record date for which precedes the relevant Registration Date. Upon delivery of the Shares to a Bondholder in satisfaction of the Conversion Right of any converting Bondholder and the
completion of such registration in accordance with this Condition 8.3, the right of such converting Bondholder to repayment of the principal amount of the Bonds so converted shall be extinguished. 
  

	(e)	Interest Accrual: On the Conversion Date, the Issuer shall pay to each Bondholder (i) any interest otherwise accruing on converted Bonds since the Interest Payment Date
last preceding the Conversion Date, and (ii) Break Cost (as defined in the Trust Deed). 

  

	(f)	Equivalent Amounts: 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, the Issuer will pay to the Bondholder or his designee an amount (the Equivalent Amount) equal to any 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 means of a U.S. dollar cheque drawn on a bank in New York City and sent to the address specified in the relevant Conversion Notice or to the relevant Bondholder if no Conversion Notice has been delivered.

  

	8.4	Undertakings

be made by cheque, the cheque will be mailed (at the risk and, if mailed at the request of the holder otherwise than by ordinary mail, expense of the holder) on the due date for payment (or, if it is not a business day, the immediately following
business day) or, in the case of a payment of principal, premium (if any) or a payment of interest due otherwise than on an Interest Payment Date, if later, on the business day on which the relevant Certificate is surrendered at the specified office
of an Agent. 
  

	9.5	Delay In Payment 

 Bondholders will not be
entitled to any interest or other payment for any delay after the due date in receiving the amount due if the due date is not a business day, if the Bondholder is late in surrendering its Certificate (if required to do so) or if a cheque mailed in

each case without prejudice to Condition 11).

evidence thereof in which event it shall be conclusive and binding on the Bondholders. 

  

	(b)	If the Issuer gives a Tax Redemption Notice pursuant to Condition 10.2(a), each Bondholder will have the right to elect that its Bond(s) shall not be redeemed and that the
provisions of Condition 11 shall not apply in respect of any payment of principal, premium (if any) or interest to be made in respect of such Bond(s) which falls due after the relevant Tax Redemption Date whereupon no additional amounts shall be

compelled by law. In such event, the Issuer will pay such additional amounts as will result in the receipt by the Bondholders and other Finance Parties of the net amounts after such deduction or withholding equal to the amounts which would otherwise
have been receivable by them had no such deduction or withholding been required except that no such additional amount shall be payable in respect of any Bond:

	 	(i)	a Tax Credit is attributable to that Tax Payment; and 

  

	 	(ii)	it has used and retained that Tax Credit,

shall have been so directed by an Extraordinary Resolution and (b) it shall have been indemnified and/or secured to its satisfaction. No Bondholder will
be entitled to proceed directly against the Issuer unless the Trustee, having become bound to do so, fails to do so within a reasonable period and such failure shall be continuing. 
  

	15.	Meetings of Bondholders, Modification and Waiver 

  

	15.1	Meetings 

 The Trust Deed contains provisions for convening meetings of Bondholders to consider any matter affecting their interests, including the sanctioning by Extraordinary Resolution of a modification of the Bonds or the
provisions of the Trust Deed or the Security Agreement. The quorum at any such meeting for passing an Extraordinary Resolution will be one or more persons holding or representing over 50 per cent. in principal amount of the Bonds for the time
being outstanding or, at any adjourned such meeting, one or more persons being or representing Bondholders whatever the principal amount of the Bonds so held or represented unless the business of such meeting includes consideration of proposals,
inter alia, (i) to modify the due date for any payment in respect of the Bonds, (ii) to reduce or cancel the amount of principal, premium (if any), interest or Equivalent Amount payable in respect of the Bonds, (iii) to change the
currency of payment of the Bonds, (iv) to modify or cancel the Conversion Right or the Security, or (v) to modify the provisions concerning the quorum required at any meeting of the Bondholders or the majority required to pass an
Extraordinary Resolution, in which case the necessary quorum for passing an Extraordinary Resolution will be one or more persons holding or representing not less than 66 per cent., or at any adjourned such meeting not less than 33 per
cent. in principal amount of the Bonds for the time being outstanding. An Extraordinary Resolution passed at any meeting of Bondholders will be binding on all Bondholders, whether or not they are present at the meeting. The Trust Deed provides that
a written resolution signed by or on behalf of the holders of not less than 66 2/3 per cent. of the aggregate principal
amount of Bonds outstanding shall be as valid and effective as a duly passed Extraordinary Resolution. The Trust Deed contains provisions for convening a single meeting of the holders of the Tranche A Bonds and the holders of the Bonds of the Issuer
in certain circumstances. 
  

	15.2	Modification and Waiver 

 The Trustee may
agree, without the consent of the Bondholders, to (i) any modification (except as mentioned in Condition 15.1 above) to, or the waiver or authorisation of any breach or proposed breach of, the Bonds, the Agency Agreement, the Trust Deed or any
Security Document which is in its opinion proper to make if, in the opinion of the Trustee, it is not materially prejudicial to the interests of the Bondholders or (ii) any modification to the Bonds, the Agency Agreement, the Trust Deed or any
Security Document which, in the Trustee’s opinion, is of a formal, minor or technical nature or to correct a manifest error or (to the satisfaction of the Trustee) proven error to comply with mandatory provisions of law or determine, without
any such consent as aforesaid, that any Event of Default or Potential Event of Default (as defined in the Trust Deed) shall not be treated as such (provided that, in any such case, it is not, in the opinion of the Trustee, materially prejudicial to
the interests of the Bondholders). Any such modification, waiver, authorisation or determination will be binding on the Bondholders and, unless the Trustee agrees otherwise, any such modifications will be notified by the Issuer to the Bondholders as
soon as practicable thereafter. 
  

	16.	Interests of Bondholders 

 In connection with the
exercise of its functions (including but not limited to those in relation to any proposed modification, authorisation, waiver, determination or substitution) the Trustee shall have regard to the general interests of the holders of the Tranche A
Bonds and the holders of the Tranche B Bonds (or holders of the Tranche A Bonds or holders of the Tranche B Bonds affected thereby) as a class but shall not have regard to any interests arising from circumstances particular to individual 

  

 106 

 
holders of the Tranche A Bonds or Tranche B Bonds (whatever their number) and, in particular but without limitation, shall not have regard to the
consequences of such exercise for individual holders of Tranche A Bonds or Tranche B Bonds (whatever their number) resulting from their being for any purpose domiciled or resident in, or otherwise connected with, or subject to the jurisdiction of,
any particular territory or any political sub-division thereof and the Trustee shall not be entitled to require, nor shall any holder of Tranche A Bonds or Tranche B Bonds be entitled to claim, from the Issuer or the Trustee or any other person, any
indemnification or payment in respect of any tax consequences of any such exercise upon individual holders of Tranche A Bonds or Tranche B Bonds except to the extent provided for in Condition 10 and/or any undertakings given in addition thereto or
in substitution therefor pursuant to the Trust Deed. 
  

	17.	Replacement of Certificates 

 If any Certificate is
mutilated, defaced, destroyed, stolen or lost, it may be replaced at the specified office of the Registrar or any Agent upon payment by the claimant of such costs as may be incurred in connection therewith and on such terms as to evidence and
indemnity as the Issuer and such Agent may reasonably require. Mutilated or defaced Certificates must be surrendered before replacements will be issued. 
  

	18.	Agents 

 The names of the initial Agents and the
Registrar and their specified offices are set out below. The Issuer reserves the right, subject to the prior written approval of the Trustee, at any time to vary or terminate the appointment of any Agent or the Registrar and to appoint additional or
other Agents or a replacement Registrar. The Issuer will at all times maintain (a) a Principal Agent, (b) a Paying Agent with a specified office in a European Union member state that will not be obliged to withhold or deduct tax pursuant
to European Council Directive 2003/48/EC or any law implementing or complying with, or introduced in order to conform, to such Directive, and (c) a Registrar which will maintain the register of Bondholders outside the United Kingdom and Hong
Kong. Notice of any such termination or appointment, of any changes in the specified offices of any Agent or the Registrar and of any change in the identity of the Registrar or the Principal Agent will be given promptly by the Issuer to the
Bondholders and in any event not less than 45 days’ notice will be given. 
  

	19.	Notices 

 All notices to Bondholders shall be
validly given if mailed to them at their respective addresses in the Register of Bondholders maintained by the Registrar or published in a leading newspaper having general circulation in Hong Kong or, if such publication shall not be practicable, in
an English language newspaper of general circulation in Asia. Any such notice shall be deemed to have been given on the date of such publication or, as the case may be, the seventh day after being so mailed. 
 Notices to be given by any Bondholder shall be in writing and given by lodging the same, together with the relative Certificate, with the Registrar, of if
the Certificates are held in a clearing system, may be given through the clearing system in accordance with its standard rules and procedures. 
  

	20.	Indemnification 

 The Trust Deed contains provisions
for the indemnification of the Trustee and for its relief from responsibility, including provisions relieving it from taking any action unless indemnified and/or secured to its satisfaction. The Trustee is entitled to enter into business
transactions with the Issuer and any entity related to the Issuer without accounting for any profit. 
  

 107 

	21.	Contracts (Rights of Third Parties) Act 1999 

 No
person shall have any right to enforce any term or condition of the Bonds or any provision of the Trust Deed under the Contracts (Rights of Third Parties) Act 1999. 
  

	22.	Governing Law and Submission to Jurisdiction 

 The
Bonds, the Trust Deed, the Agency Agreement and the Issuer Security Agreement are governed by, and shall be construed in accordance with, the laws of England. The AST (HK) Security Agreement and the AST (HK) Share Mortgage are governed by, and will
be construed in accordance with, the laws of Hong Kong. The Equity Pledge Agreement is governed by, and will be construed in accordance with, the laws of the PRC. In relation to any legal action or proceedings arising out of or in connection with
the Trust Deed or the Bonds (together referred to as Proceedings), the Issuer has in the Trust Deed irrevocably submitted to the non-exclusive jurisdiction of the courts of England and in relation thereto, and the Issuer has appointed
Brandmine 3 Limited at 8 Lower John Street, Golden Square, London W1F 9AU, England, as agent for service of process in England. The Trustee and the Bondholders may take any Proceedings against the Issuer in any other court of competent jurisdiction

belief, required for the offer, purchase or sale by it of Bonds under the laws and regulations in force in any jurisdiction to which it is subject or in which it makes such offers, purchases or sales and it will, to the best of its knowledge and
belief, comply with all such laws and regulations.

	 	3.2	it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to such Bonds in, from or otherwise involving the United
Kingdom. 

  

	4.	European Economic Area 

 In relation to each Member
State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), the Manager has represented and agreed that with effect from and including the date on which the Prospectus Directive is
implemented in that Relevant Member State (the Relevant Implementation Date) it has not made and 
 will not make an offer of Bonds to
the public in that Relevant Member State, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Bonds to the public in that Relevant Member State: 
  

	 	4.1	at any time to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to

Securities and Futures Ordinance (Cap. 571) of Hong Kong and any rules made under that Ordinance; or (ii) in other circumstances which do not result in the document being a “prospectus” as defined in the Companies Ordinance (Cap. 32)
of Hong Kong or which do not constitute an offer to the public within the meaning of that Ordinance; and 

  

	 	(b)	it has not issued or had in its possession for the purpose of issue, and will not issue or have in its possession for the purpose of issue, whether in Hong Kong or elsewhere, any
