Terms and Conditions of the Notes


 


The issue of the US$[*] principal amount
of 5.50% secured convertible notes (the “Notes”) pursuant to the subscription agreement by and between Earthasia International
Holdings Ltd. (泛亞環境國際控股有限公司) (the “Issuer”)
and Lexinter International Inc. (the “Investor”) dated January [*], 2021 (the “Subscription Agreement”)
..


 


1      Form, Denomination and Title


 


(A)            Form and
Denomination


 


The Notes are issued in registered
form in the minimum denomination of US$500,000 each and integral multiples of US$10,000 in excess thereof (referred to as the “principle
amount” of a Note) (the “Authorised Denomination”). A note certificate (each a “Certificate”)
will be issued to each Noteholder in respect of its registered holding of Notes. Each Certificate will be numbered serially with an identifying
number which will be recorded on the relevant Certificate and in the register of Noteholders (the “Register”) which
the Issuer will procure to be kept.


 


(B)            Conversion


 


Each Note will entitle its registered
holder to convert such Note into Shares in accordance with Condition 5 (Conversion).


 


(C)            Title


 


Title to the Notes will pass only by
transfer and registration in the Register as described in Condition 3 (Transfers of Notes; Issue of Certificates). The holder of
any Note will (except as otherwise required by law or as ordered by a court of competent jurisdiction) 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 terms
and conditions (these “Conditions”), “Noteholder” and (in relation to a Note) “holder”
mean the person in whose name a Note is registered.


 


2      Ranking


 


(A)            Status


 


The Notes constitute direct, unconditional,
unsubordinated and secured obligations of the Issuer and shall at all times rank pari passu and without any preference or priority
among themselves. The payment obligations of the Issuer under the Notes shall at all times rank senior to all of its present and future
unsecured obligations.


 


(B)            Security


 


The Notes will have the benefit of
the Security constituted by the Security Documents on a first ranking basis for all amounts payable on the Notes and all other moneys
payable by the Obligors under the Transaction Documents. The Security Documents shall become immediately enforceable if an Event of Default
occurs and is continuing, following which the Noteholder (or its appointee) may, but shall not be obligated to, take such proceedings
or other action as such Noteholder deems appropriate pursuant to the Transaction Documents.

                                                                     (A)   Register

		(C)	Delivery of New Certificates



 


Each new Certificate to be issued upon a transfer

Days of delivery of the original Certificate to the Issuer, be made available for collection at the specified office of the Issuer or,
if so requested in the form of transfer, be mailed by uninsured mail at the risk of the holder of the Notes not so transferred, converted,

		(D)	Formalities Free of Charge



 


Registration of a transfer of
Notes and issuance of new Certificates will be effected without charge by or on behalf of the Issuer subject to (a) the person

    	 	2	 



     


    

 


		(E)	No Transfer to Competitor,
Adversary or Connected Person



 


None of the Notes may be transferred to a competitor,
adversary or Connected Person of the Issuer.


 


	4	Interest



 


The Notes bear interest from and including
the Issue Date (the “First Accrual Date”) at the rate of 5.50% per annum (the “Interest Rate”) which
shall accrue daily and is payable quarterly on the 20th Business Day of March, June, September and December of each
year (each an “Interest Payment Date”) falling after the First Accrual Date, provided that, notwithstanding anything
to the contrary, the last Interest Payment Date shall instead fall on the Maturity Date.


 


Each Note will cease to bear interest
(a) where the Conversion Right attached to it shall have been exercised by a Noteholder, from and including the relevant Conversion
Date, (b) where such Note is redeemed or repaid pursuant to Condition 8 (Redemption and Cancellation) or Condition 10 (Events
of Default), from the due date for redemption or repayment thereof unless, upon due presentation thereof, payment of principal is
improperly withheld or refused. In such event, it will continue to bear interest at a rate equal to 20% per annum above the Interest Rate
(the “Default Rate”) from the date such sums are due but not paid (both before and after judgment) until (but excluding)
the day on which all sums due in respect of such Note up to that day are received by or on behalf of the relevant holder.


 


If interest is required to be calculated
for a period of less than twelve months, the relevant day-count fraction will be determined on the basis of the actual number of days
elapsed over a 365-day year.


 


In these Conditions, the period beginning
on and including the First Accrual Date and ending on but excluding the first Interest Payment Date and each successive period beginning
on and including an Interest Payment Date and ending on but excluding the next succeeding Interest Payment Date is called an “Interest
Period”.


 


Interest in respect of any Note shall
be calculated in Principal Amount Outstanding of the Notes. The amount of interest payable for any period shall be equal to the product
of the Principal Amount Outstanding, multiplied by the applicable rate of interest and the day-count fraction (determined in the same
manner as stated above in this Condition 4(Interest)) for the relevant period, rounding the resulting figure to the nearest cent
(half a cent being rounded upwards).


 


	5	Conversion



 


		(A)	Conversion Right



 


		(i)	Conversion Period: Subject as provided in these Conditions, each Note shall entitle the holder
to convert such Note into Shares credited as fully paid at any time during the Conversion Period referred to below (the “Conversion
Right”).



 


Subject to and upon compliance
with these Conditions, the Conversion Right in respect of a Note may be exercised, at the option of the holder thereof, in whole or
in part at any time and from time to time (subject to any applicable fiscal or other laws or regulations and as hereinafter
provided) on or after the Issue Date to the close of business in Hong Kong on the date falling one Business Day prior to the
Maturity Date (both days inclusive)(the “Conversion Period”), save that the Conversion Right may not be exercised
(a) on any date on which the Issuer’s register of shareholders is to be closed and (b) at any time after the
circumstance stated in subsection (viii) of Condition 5(D)(Undertakings) shall have arisen and before the Relevant
Approval shall have been obtained by the Issuer. If the final date on which the Conversion Right may be exercised is not a Business
Day, then the period for the exercise of the Conversion Right by Noteholders shall end on the immediately subsequent Business
Day.


 






    	 	3	 



     


    

 


On exercise of Conversion Right by
a Noteholder, the Issuer is entitled to request the Noteholder to provide evidence as may be reasonably requested by the Issuer to show
that such particular conversion will not result in the Issuer cease to satisfy the public float requirement under the Listing Rules, or
give rise to a general offer obligation under the Hong Kong Code on Takeovers and Mergers by the Noteholder.


 


Notwithstanding the foregoing, if solely
as a result of, and to the extent that, the issue of any Shares to the Noteholder upon such particular conversion (the “Uncovered
Shares”), (x) the Issuer would cease to satisfy the public float requirement under the Listing Rules, or (y) a general
offer obligation under the Hong Kong Code on Takeovers and Mergers in respect of the Shares would arise, the Conversion Right with respect
only to the part of the Note convertible into the Uncovered Shares shall not be exercisable until such Noteholder has taken and caused
to be taken the necessary actions to sell, assign or otherwise dispose the Shares held by such Noteholder such that the issuance of the
Uncovered Shares to such Noteholder would not result in (x) the Issuer ceasing to satisfy the public float requirement under the
Listing Rules, or (y) a general offer obligation under the Hong Kong Code on Takeovers and Mergers in respect of the Shares arising.


 


The price at which Shares will be issued
upon exercise of a Conversion Right (the “Conversion Price”) will initially be the Benchmark Price per Share, but will
be subject to adjustment in the circumstances described in Conditions 5(C)(Adjustment to Conversion Price).


 


		(ii)	The number of Shares to be issued on exercise of a Conversion Right shall be determined by dividing the
                                                                  amount equal to 100% of the principal amount of the Notes being the subject of conversion together with the interest accrued but
                                                                  unpaid thereon as to the Conversion Date (inclusive), by the Conversion Price in effect on the relevant Conversion Date. A
                                                                  Conversion Right may be exercised in respect of one or more Notes. If more than one Note 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 Notes to be converted.



 


		(iii)	Fractions of Shares: Fractions of Shares will not be issued on exercise of Conversion Rights and
no cash payment or other adjustment will be made in lieu thereof. However, if the Conversion Right in respect of more than one Note is
exercised at any one time such that Shares to be issued on conversion are to be registered in the same name, the number of such Shares
to be issued in respect thereof shall be calculated on the basis of the aggregate principal amount of such Notes being so converted and
rounded down to the nearest whole number of Shares. Notwithstanding the foregoing, in the event of a consolidation or reclassification
of Shares by operation of law or otherwise occurring after the Issue Date which reduces the number of Shares outstanding, the Issuer will
upon conversion of Notes pay in cash in United States dollars a sum equal to such portion of the principal amount of the Note or Notes
evidenced by the Certificate deposited in connection with the exercise of Conversion Rights, aggregated as provided in subsection (i) of
Condition 5(A)(Conversion Right), as corresponds to any fraction of a Share not issued as a result of such consolidation or reclassification
aforesaid, provided that such sum exceeds US$100. Any such sum shall be paid not later than five Trading Days after the relevant Conversion
Date by a United States dollar cheque drawn on, or by transfer to a United States dollar account maintained by the payee with, a bank
in Hong Kong, in accordance with instructions given by the relevant Noteholder in the Conversion Notice.



 






    	 	4	 



     


    

 


		(iv)	Revival and/or Survival after Default: Notwithstanding the provisions in subsection (i) of
Condition 5(A)(Conversion Right), if (a) the Issuer shall default in making payment in full in respect of any Note which shall
have been called for redemption on the date fixed for redemption thereof; (b) any Note
has become due and payable prior to the Maturity Date by reason of the occurrence of any of the events under Condition 10 (Events of
Default); or (c) any Note is not redeemed on the Maturity Date in accordance with Condition 8(A)(Method of Payment), the
Conversion Right attaching to such Note 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 Note is deposited for conversion) on the date upon which the full amount of the moneys
payable in respect of such Note has been duly received by the Noteholders and notwithstanding the provisions of subsection (i) of
Condition 5(A)(Conversion Right), any Note in respect of which the Certificate and Conversion Notice are deposited for conversion
prior to such date shall be converted on the relevant Conversion Date notwithstanding that the full amount of the moneys payable in respect
of such Note shall have been received by the Noteholders before such Conversion Date or that the Conversion Period may have expired before
such Conversion Date.



 


		(v)	Meaning of “Shares”: As used in these Conditions, the expression “Shares”
means ordinary shares of the Issuer or shares of any class or classes resulting from any subdivision, consolidation or re-classification
of those shares, which as between themselves have no preference in respect of dividends or of amounts payable in the event of any voluntary
or involuntary liquidation or dissolution of the Issuer.



 


		(B)	Conversion Procedure



 


		(i)	Conversion Notice: Conversion Rights may be exercised
by a Noteholder during the Conversion Period by delivering the relevant Certificate to the specified office of the Issuer during its
usual business hours accompanied by a duly completed and signed notice of conversion (a “Conversion Notice”) in the
form set out in Exhibit B. Conversion Rights shall be exercised subject in each case to any applicable fiscal or other laws or regulations
applicable in Hong Kong.



 


If such delivery is made after the end
of normal business hours (being 3.00 p.m.) or on a day which is not a Business Day, such delivery shall be deemed for all purposes of
these Conditions to have been made on the next following such Business Day.


 


Conversion Rights may be exercised in
respect of all or part of the Principal Amount Outstanding of a Note, in each case at the Noteholder’s option, but may only be exercised
in respect of an Authorised Denomination.


 


The conversion date in respect of a
Note (the “Conversion Date”) shall be deemed to be the Trading Day immediately following the date of the surrender
of the Certificate in respect of such Note and delivery of such Conversion Notice and, if applicable, any such abovementioned certification
or any payment to be made or indemnity given under these Conditions in connection with the exercise of such Conversion Right.


 


		(ii)	Stamp Duty etc.: The Issuer must pay any capital,
stamp, issue, registration, transfer or similar Taxes and duties arising on conversion (the “Conversion Taxes”) and
the Issuer must also pay if any, Taxes arising by reference to any disposal or deemed disposal of a Note in connection with such conversion
and all other expenses arising on the issue of Shares on conversion of Notes and all charges of the share transfer agent for the Shares.



 






    	 	5	 



     


    

 


		(iii)	Registration: Upon exercise by a Noteholder of its
Conversion Right and compliance with subsections (i) and (ii) of Condition 5(B)(Conversion Procedure) the Issuer will,
as soon as practicable, and in any event not later than five Trading Days after the Conversion Date, register the person or persons,
other than a Connected Person, designated to receive the Conversion Shares as set forth in the Conversion Notice as holder(s) of
the relevant number of Shares in the Issuer’s share register and will, if the Noteholder has also requested in the Conversion Notice
and to the extent permitted under applicable law and the rules and procedures of the Central Clearing and Settlement System of Hong
Kong (“CCASS”) effective from time to time, take all necessary action to
procure that Shares are delivered through CCASS for so long as the Shares are listed on the HKSE; or will make such certificate or certificates
available for collection at the office of the Issuer’s share registrar in Hong Kong (currently Tricor Hong Kong Investor Services
Limited) notified to Noteholders in accordance with Condition 11 (Notices) 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 share certificate will be issued in respect of all Shares issued on conversion of Notes subject to the same Conversion Notice and
which are to be registered in the same name.



 


The delivery of the Shares to the converting Noteholder
(or such person or persons, other than a Connected Person, designated in the relevant Conversion Notice) in the manner contemplated above
in this Condition 5(B)(iii) will be deemed to satisfy the Issuer’s obligation to pay the principal, interest and premium (if
any) on such converted Notes.


 


If the Conversion Date in relation to the conversion
of any Note shall be after the record date for any issue, distribution, grant, offer or other event as gives rise to the adjustment of
the Conversion Price pursuant to Condition 5(C)(Adjustment to Conversion Price), but before the relevant adjustment becomes effective
(the “Relevant Effective Date”) under the relevant Condition (a “Retroactive Adjustment”), upon
the relevant adjustment becoming effective the Issuer shall procure the issue to the converting Noteholder (or in accordance with the
instructions contained in the Conversion Notice (subject to applicable exchange control or other laws or other regulations)), such additional
number of Shares (“Additional Shares”) as is, together with Shares to be issued on conversion of the Note(s), equal
to the number of Shares which would have been required to be issued on conversion of such Note if the relevant adjustment to the Conversion
Price had been made and become effective on or immediately after the relevant record date and in such event and in respect of such Additional
Shares references in this Condition 5(B)(iii) to the Conversion Date shall be deemed to refer to the Relevant Effective Date (notwithstanding
that the Relevant Effective Date falls after the end of the Conversion Period).


 


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


 


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


 


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

		(C)	Adjustments to Conversion
Price



 


The Conversion Price will be subject to adjustment as follows:


 


		(1)	Failure to issue and grant Warrants. In the event the Issuer is unable to obtain the Specific Mandate
or approval from the HKSE to grant and issue the Warrant and the Warrant Shares by the Long Stop Date and the Investor elects to terminate
the Subscription Agreement, the Conversion Price shall be adjusted downward to the benchmarked price of the Shares under Rule 13.36(2) of
the Listing Rules as of the date of the Subscription Agreement.



 


		(2)	Share Dividends. In the event that the Issuer makes a dividend or other distribution in Shares
to holders of Shares, the Conversion Price shall be reduced by multiplying the Conversion Price in effect immediately prior to the close
of business on the date fixed for the determination of shareholders entitled to such dividend or distribution by a fraction, the numerator
of which is the number of Shares in issue at the close of business on the date fixed for such determination and the denominator of which
is such number of Shares plus the total number of Shares constituting such dividend or other distribution, such decrease in the Conversion
Price to become effective immediately prior to the opening of business on the day following the date fixed for such determination.



 


		(3)	Subdivisions and Combinations. In the event that outstanding Shares are subdivided into a greater
number of Shares, the Conversion Price in effect immediately prior to the effectiveness of such subdivision shall be proportionately reduced,
and, conversely, in the event that outstanding Shares are combined into a smaller number of Shares, the Conversion Price in effect immediately
prior to the effectiveness of such combination shall be proportionately increased. If the Conversion Price is reduced or increased pursuant
to this Condition 5(C)(3). Such reduction or increase of the Conversion Price shall become effective simultaneously with the effectiveness
of such subdivision or combination.



 


		(4)	Distributions. In the event that the Issuer distributes to holders of Shares, by dividend or otherwise,
evidences of its indebtedness, shares of any class of its capital stock, cash or other assets (including securities, but excluding (i) any
dividend or distribution paid exclusively in cash out of the aggregate net profits (less losses) attributable to Shares for all financial
periods after June 30, 2020 and (ii) any dividend or distribution referred to in Condition 5(C)(2)(Share Dividends)),
the Conversion Price shall be reduced by multiplying the Conversion Price in effect immediately prior to the close of business on the
date fixed for the determination of shareholders entitled to such distribution by a fraction, the numerator of which is (x) such
then current Conversion Price less (y) the aggregate fair market value on such date of the evidences of indebtedness, shares of capital
stock, cash and other assets to be distributed divided by the number of Shares in issue at the close of business on such date, and the
denominator of which is such then current Conversion Price, such reduction to become effective immediately prior to the opening of business
on the day following such date.



 


		(5)	Share Reclassifications. The reclassification of Shares into securities which include securities
other than Shares shall be deemed to involve (i) a distribution of such securities other than Shares to all holders of Shares within
the meaning of Condition 5(C)(4)(Distributions) (and the effective date of such reclassification shall be deemed to be "the
date fixed for the determination of shareholders entitled to such distribution" within the meaning of Condition 5(C)(4)(Distributions))
and (ii) a subdivision of the number of Shares in issue immediately prior to such reclassification into the number of Shares in issue
immediately thereafter within the meaning of Condition 5(C)(3)(Subdivisions and Combinations) (and the effective date of such reclassification
shall be deemed to be the date of effectiveness of such subdivision or combination, as the case may be, for
purposes of Condition 5(C)(3)(Subdivisions and Combinations)).

		(6)	Rights Issues. In the event that the Issuer offers to holders of any Shares new Shares for subscription
by way of rights, or grants to holders of Shares any options or warrants to subscribe for new Shares, at a price (“New Rights
Issue Price”) that is less than the Conversion Price, the Conversion Price shall be reduced to equal the New Rights Issue Price,
such adjustment to become effective (if appropriate retroactively) immediately prior to the opening of business on the next day following
the record date for the offer or grant.



 


		(7)	Issuance of Shares Below Conversion Price or New Securities for Total Effective Consideration Below
Conversion Price



 


		(i)	In the event that the Issuer issues any Shares for consideration per share (“New Share Issue
Price”) that is less than the Conversion Price in effect immediately prior to such issuance, the Conversion Price shall be reduced
to equal the New Share Issue Price, such reduction to become effective on the date of the issuance;



 


		(ii)	In the event that the Issuer issues any securities that by their terms are convertible into or exchangeable
for or carry rights of subscription for new Shares ("Share Equivalents") and the Total Effective Consideration per Share
receivable for such Share Equivalents at the time of issuance (“New Share Equivalent Issue Price”) is less than the
Conversion Price in effect immediately prior to such issuance, the Conversion Price shall be reduced to equal the New Share Equivalent
Issue Price, such reduction to become effective on the date of issuance;



 


		(iii)	In the event that after the date of issuance of the Share Equivalents, the rights of conversion or exchange
or subscription attached to any Share Equivalents are modified so that the Total Effective Consideration per Share receivable for such
Share Equivalents (the “New Share Equivalent Conversion Price”) becomes less than the Conversion Price in effect immediately
prior to the effectiveness of such New Share Equivalent Conversion Price, the Conversion Price shall be reduced to equal such New Share
Equivalent Conversion Price. Such reduction shall become effective simultaneously with the effectiveness of such New Share Equivalent
Conversion Price. A right of conversion or exchange or subscription shall not be treated as modified for the foregoing purposes to the
extent that it is adjusted to take account of events giving rise to an adjustment of the Conversion Price pursuant to this Condition 5.



 


		(iv)	For the purposes of Condition 5, the "Total Effective Consideration" receivable for the
Share Equivalents issued shall be deemed to be the consideration receivable by the Issuer for any such Share Equivalents plus the additional
minimum consideration (if any) to be received by the Issuer upon (and assuming) the conversion or exchange thereof or the exercise of
such subscription rights, and the "Total Effective Consideration per Share" receivable for such Share Equivalents shall
initially be such aggregate consideration divided by the number of Shares to be issued upon (and assuming) such conversion or exchange
at the initial conversion or exchange rate or the exercise of such subscription rights at the initial subscription price, in each case
without any deduction for any commissions, discounts or expenses paid, allowed or incurred in connection with the issuance.



 


		(8)	Modification of Rights. Without limiting any other provision of this Condition 5, if the Issuer
or any Subsidiary shall in any way modify the rights attached to any share or loan capital so as wholly or partly to exchange or make
convertible such share or loan capital into, or attach thereto any rights to acquire, Shares, the Issuer shall appoint an approved auditor
to consider whether any adjustment to the Conversion Price is appropriate, and if such approved auditor shall certify that any such adjustment
is appropriate the Conversion Price shall be adjusted accordingly.



 






    	 	8	 



     


    

 


		(9)	Other Changes. If the Issuer at any time proposes to take any action affecting the Shares similar
to or having an effect similar to any of the actions described in any of Condition 5 (but not including any action described in
any such Condition), then the Board shall consider in good faith whether any adjustment of the Conversion Price is appropriate and, if
so, the amount of such adjustment. The Issuer shall notify the Holders of the Board's determination not less than ten (10) days prior
to the effectiveness of such proposed action. If Majority Noteholders gives notice to the Issuer within thirty (30) days after delivery
of such notice to the Holders, or if the Issuer fails to give such notice as required above, then upon the request of Majority Noteholders
an approved auditor shall determine whether an adjustment of the Conversion Price is appropriate and, if so, the amount of such adjustment.



 


		(10)	Value of Consideration. In case at any time any Shares or Share Equivalents are issued or sold
for cash, the consideration received therefor shall be deemed to be the amount received by the Issuer therefor, without deduction therefrom
of any expenses incurred or any underwriting commissions or concessions or discounts paid or allowed by the Issuer in connection therewith.
In case any Shares or Share Equivalents are issued or sold for a consideration other than cash, the amount of the consideration other
than cash received by the Issuer shall be deemed to be the fair market value of such consideration, with deduction therefrom of any expenses
incurred or any underwriting commissions or concessions or discounts paid or allowed by the Issuer in connection therewith by the Board
of Directors of the Issuer.



 


		(11)	Limitations. The provisions of paragraphs Conditions 5(C)(6) through 5(C)(7) shall not
apply to an issue of Shares or other securities of the Issuer wholly or partly convertible into, or rights to acquire, Shares to officers
or employees of the Issuer or any of its subsidiaries pursuant to any employee or executive share scheme in existence as at the date of
issue of each Note.



 


		(12)	Definitions. For purpose of this Condition 5:



 


		(i)	"announcement" shall include the release of an announcement to the press or the delivery
or transmission by telephone, telex or otherwise of an announcement to HKSE, and "date of announcement" shall mean the date
on which the announcement is first so released, delivered or transmitted;



 


		(ii)	"approved auditor" means an auditing firm of international repute selected by Majority
Noteholders for the purpose of providing a specific opinion or calculation or determination hereunder;



 


		(iii)	"fair market value" of any capital stock or other assets means fair market value as determined
by the Board in good faith and set forth in a Board Resolution and a written notice delivered to the Holders, provided that if, within
thirty (30) days after delivery of such notice to the Holders, Majority Noteholders objects to such determination, the fair market value
of such capital stock or other assets shall be as determined by an approved auditor;



 


		(iv)	"issue" shall include allot;

		(13)	Miscellaneous. No adjustment in the Conversion Price shall be required unless such adjustment (plus
any other adjustments not previously made by reason of this Condition 5(C)(13)) would require an increase or decrease of at least 0.1%
in the Conversion Price; provided that any adjustments which by reason of this paragraph (m) are not required to be made shall be
carried forward and taken into account in any subsequent adjustment. All calculations under this Condition 5 shall be made to the nearest
cent, to the nearest one-hundredth of a percentage point or to the nearest one-hundredth of a share, as the case may be.



 


		(14)	Notice of Adjustments of Conversion Price. Whenever the Conversion Price is adjusted as herein
provided, the Issuer shall compute the adjusted Conversion Price in accordance with this Condition 5 and shall prepare a certificate signed
by the Chief Financial Officer of the Issuer setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon
which such adjustment is based, and such certificate shall forthwith be delivered to each Holder. If Majority Noteholders gives notice
to the Issuer objecting to such calculation or stating that, in the opinion of such Majority Noteholders, an event has occurred that requires
an adjustment to the Conversion Price pursuant to Condition 5 but no notice of adjustment has been given by the Issuer, an approved auditor
shall be appointed within ten (10) Business Days after delivery of such notice from the Majority Noteholders to determine the appropriate
adjustment of the Conversion Price, if any, and such determination shall be final and binding on the Issuer and the Holder.



 


(D) Undertakings


 


Without prejudice to the undertakings made by the Issuer
in favour of the Investor as set forth in the Subscription Agreement, the Issuer undertakes that so long as any Note remains outstanding:


 


		(i)	it will (a) maintain a listing for all the issued Shares on the HKSE, and (b) obtain and maintain a listing for all the
Shares issued on the exercise of the Conversion Rights on the HKSE;



 


		(ii)	it will pay the expenses of the issue of, and all expenses of obtaining listing for, Shares arising on conversion of the Notes;



 


		(iii)	without prior written consent of the Majority Noteholders, it will not make any reduction of its ordinary
share capital or any uncalled liability in respect thereof or of any share premium account except, in each case, where the reduction is
permitted by applicable law and results in (or would, but for the provision of these Conditions relating to rounding or the carry forward
of adjustments, result in) an adjustment to the Conversion Price or is otherwise taken into account for the purposes of determining whether
such an adjustment should be made provided always that the Issuer shall not be prohibited from purchasing its Shares to the extent permitted
by law;



 


		(iv)	it will reserve, free and clear of all liens, claims, charges, security, encumbrances or like interests,
any other pre-emptive or other similar rights, out of its authorised but unissued ordinary share capital the full number of Shares liable
to be issued on conversion of the Notes from time to time remaining outstanding and shall ensure that all Shares delivered on conversion
of the Notes will be duly and validly issued as fully-paid, and the HKSE shall have granted its approval for the listing of, and permission
to deal in, the Shares delivered on conversion of the Notes on the Main Board;



 


		(v)	it will not make any offer, issue, grant or distribute or take any action the effect of which would be
to reduce the Conversion Price below the par value of the Shares of the Issuer, provided always that the Issuer shall not be prohibited
from purchasing its Shares to the extent permitted by law;



 






    10 


     


    

 


		(vi)	unless so required by applicable law or regulation or the articles of association of the Issuer or in
order to establish a dividend or other rights attaching to the Shares, it will not close its register of Shareholders or take any other
action which prevents the transfer of its Shares generally and ensure that the Notes
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 although not as against the Issuer) at all times while the register is closed or such other action is effective,
nor take any action which prevents the conversion of the Notes or issue of Shares in respect of them otherwise than in accordance with
these Conditions;



 


		(vii)	where exercise of the Conversion Rights pursuant to the terms and conditions hereof would result in (i) the
Issuer not being able to satisfy the HKSE’s public shareholding requirement (i.e. 25% public float) under Rule 8.08 of the
Listing Rules following such exercise, or (ii) conversion of all or part of the Note would trigger a mandatory offer under rule 26
of the Takeovers Code on the part of the Holder and/or any person(s) acting in concerti with such Holder, it shall immediately notify
the Noteholder of such restrictions on conversion upon arising thereof; and



 


		(viii)	if at any time the Conversion Price is adjusted in accordance with these Conditions resulting in an increase
to the number of Shares falling to be issued on conversion of the Notes and the General Mandate shall become insufficient to satisfy full
conversion of the Notes, then the Issuer shall promptly:



 


		(a)	convene a general meeting of its Shareholders for the grant of specific mandate to the Issuer’s
board of directors permitting the issue of further Shares in amount sufficient to satisfy full conversion of the Notes; and



 


		(b)	seek from HKSE approval for listing of the further Shares,
	 	 	 
	 	(collectively, the “Relevant Approval”).

following day which is a Payment Business Day) will be initiated and, 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 Payment Business Day, the immediately following Payment Business Day) or, in the case of a payment of principal, premium
and interest due other than on an Interest Payment Date, if later, on the Payment Business Day on which the relevant Certificate is surrendered
at the specified office of an Agent.

Noteholders 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 Payment Business Day,

		(i)	Appointment: Each Noteholder by such Noteholder’s acceptance of the benefits of this Note,
hereby designates the Investor as the Security Agent to act as specified herein and in the Transaction Documents. Each Noteholder shall
be deemed irrevocably to authorize the Security Agent to take such action on its behalf under the provisions of the Transaction Documents
and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of the Security
Agent by the terms hereof and thereof and such other powers as are reasonably incidental hereto and thereto. The Security Agent may perform

forth in the Transaction Documents. Neither the Security Agent nor any of its partners, members, shareholders, officers, directors, employees
or agents shall be liable for any action taken or omitted by it as such hereunder or under the Transaction Documents or in connection

and affairs of the Issuer and the applicable Obligor in connection with such Secured Party’s investment in the Issuer, the creation
and continuance of the obligations, and the taking or not taking of any action in connection therewith, and (ii) its own appraisal
of the creditworthiness of the Issuer, each Obligor and of the value of the Transaction Security from time to time, and the Security Agent
shall have no duty or responsibility, either initially or on a continuing basis, to provide any Secured Party with any credit, market
or other information with respect thereto, whether coming into its possession before any obligations are incurred or at any time or times
thereafter. The Security Agent shall not be responsible to the Issuer, any Obligor or any Secured Party for any recitals, statements,
information, representations or warranties herein or in any document, certificate or other writing delivered in connection herewith, or
for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectability, priority or sufficiency of the Transaction
Documents, or for the financial condition of the Issuer or Obligor or the value of any of the Transaction Security, or be required to
make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of the Transaction Documents,
or the financial condition of the Issuer or any Obligor, or the value of any of the Transaction Security, or the existence or possible
existence of any default or Event of Default under the Transaction Documents or the Notes. The Security Agent shall have no obligation
whatsoever to any Secured Party to assure that the Transaction Security exists or is owned by the Issuer or any Obligor or is cared for,
protected or insured or that the liens granted pursuant to the Transaction Documents have been properly or sufficiently or lawfully created,
perfected, or enforced or are entitled to any particular priority. The Security Agent shall be entitled to rely, and shall be fully protected
in relying, upon any writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram,
order or other document or telephone message signed, sent or made by the proper person or entity, and, with respect to all legal matters
pertaining to the Transaction Documents and its duties hereunder and thereunder.



 


		(iv)	Rights: The Security Agent shall have the right to take any action with respect to the Transaction
Security, on behalf of all of the Secured Parties. To the extent practical, the Security Agent shall request instructions from the Secured
Parties with respect to any material act or action (including failure to act) in connection with the Transaction Documents, and shall
be entitled to act or refrain from acting in accordance with the instructions of the Secured Parties; if such instructions are not provided
despite the Security Agent’s request therefor, the Security Agent shall be entitled to refrain from such act or taking such action,
and if such action is taken, shall be entitled to appropriate indemnification from the Secured Parties in respect of actions to be taken
by the Security Agent; and the Security Agent shall not incur liability to any person or entity by reason of so refraining. Without limiting
the foregoing, (a) no Secured Party shall have any right of action whatsoever against the Security Agent as a result of the Security
Agent acting or refraining from acting hereunder in accordance with the terms of the Transaction Documents, and the Issuer and the Obligors
shall have no right to question or challenge the authority of, or the instructions given to, the Security Agent pursuant to the foregoing,
and (b) the Security Agent shall not be required to take any action which the Security Agent believes (i) could reasonably be
expected to expose it to personal liability or (ii) is contrary to the Transaction Documents or applicable law.



 






    18 


     


    

 


		(v)	Resignation: The Security Agent may resign from the performance of all its functions and duties
under the Transaction Documents at any time by giving 30 days' prior written notice (as provided in the Subscription Agreement) to the
Issuer. Upon any such notice of resignation, the Secured Parties shall appoint a successor Security Agent hereunder.



 


		(vi)	Indemnification: To the extent that the Security Agent is not reimbursed and indemnified by the
Issuer or any Obligor, the Secured Parties will jointly and severally reimburse and indemnify the Security Agent, in proportion to their
initially purchased respective principal amounts of Notes, from and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted
against the Security Agent in performing its duties under the Transaction Documents, or in any way relating to or arising out of the Transaction
Documents, except for those determined by a final judgment (not subject to further appeal) of a court of competent jurisdiction to have
resulted solely from the Security Agent's own gross negligence or willful misconduct. Prior to taking any action hereunder as Security
Agent, the Security Agent may require each Secured Party to deposit with it sufficient sums as it determines in good faith is necessary
to protect the Security Agent for costs and expenses associated with taking such action.



 


		(B)	Rights with respect to
Transaction Security



 


Each Secured Party agrees with all
other Secured Parties and the Security Agent (i) that it shall not, and shall not attempt to, exercise any rights with respect to
its security interest in the Transaction Security, whether pursuant to any other agreement or otherwise (other than pursuant to the Transaction
Documents), or take or institute any action against the Security Agent or any of the other Secured Parties in respect of the Transaction
Security or its rights thereunder and (ii) that such Secured Party has no other rights with respect to the Transaction Security other
than as set forth in the Security Documents.


 


		(C)	Application of Proceeds



 


If the Security Agent receives a payment
that is insufficient to discharge all the amounts then due and payable by the Issuer and the Obligors under the Transaction Documents,
the Security Agent shall apply that payment towards the obligations of the Issuer and the Obligors under the Transaction Documents in
the following order: first, in or towards payment pro rata of any unpaid fees, costs and expenses of and other amounts owing to,
the Security Agent; secondly, in or towards payment pro rata of all payable amounts due but unpaid under the Notes.


 


		(D)	Consent Threshold



 


Where under these Conditions, any matter
is expressed to require the consent, approval, waiver or determination of the Secured Parties, such consent, approval, waiver or determination
shall, except as otherwise stated, be deemed to be given or made if agreed to by the Majority Noteholders.


 


Subject to the other provisions in
this Condition 14(Enforcement) and the Transaction Documents, at any time after the Notes have become due and repayable, Majority
Noteholders may be way of resolution, at their discretion and without further notice to the Issuer, take such proceedings against the

Noteholders may think fit to enforce repayment of the Notes and to enforce the provisions of these Conditions.

REGULATIONS CONCERNING THE TRANSFER AND REGISTRATION
OF NOTES


 


		1	Each Note shall be in a minimum
denomination of US$500,000. Certificates, each evidencing entitlement to one or more Notes, shall be issued in accordance with the Conditions.



 


		2	The Notes are transferable by
execution of the form of transfer on each Certificate endorsed under the hand of the transferor or, where the transferor is a corporation,
under its common seal or under the hand of a director or a duly authorised officer in writing. In this Exhibit “transferor”
shall where the context permits or requires include joint transferors and be construed accordingly.



 


		3	The Certificate issued in respect
of the Note to be transferred must be delivered for registration to the specified office of the Issuer (currently at 11/F, COFCO Tower,
262 Gloucester Road, Causeway Bay, Hong Kong) accompanied by such other evidence (including certificates and/or legal opinions) as the
Issuer may reasonably require to prove the title of the transferor or his right to transfer the Note and his identity and, if the form
of transfer is executed by some other person on his behalf or in the case of the execution of a form of transfer on behalf of a corporation
by its officers, the authority of that person or those persons to do so. The signature of the person effecting a transfer of a Note shall
conform to any list of duly authorised specimen signatures supplied by the registered holder or be certified by a recognised bank, notary
public or in such other manner as the Issuer may require.



 


		4	The executors or administrators
of a deceased holder of Notes (not being one of several joint holders) and, in the case of the death of one or more of joint holders,
the survivor or survivors of such joint holders, shall be the only persons recognised by the Issuer as having any title to such Notes.



 


		5	Any person becoming entitled to
Notes in consequence of the death or bankruptcy of the holder of such Notes may, upon producing such evidence that he holds the position
in respect of which he proposes to act under this paragraph or of his title as the Issuer shall require (including certificates and/or
legal opinions), be registered himself as the holder of such Notes or, subject to the preceding paragraphs as to transfer, may transfer
such Notes. The Issuer may retain any amount payable upon the Notes to which any person is so entitled until such person shall be so
registered or shall duly transfer the Notes.



 


		6	Unless otherwise requested by
him and agreed by the Issuer, a holder of Notes shall be entitled to receive only one Certificate in respect of his holding.



 


		7	The joint holders of a Note shall
be entitled to one Certificate only in respect of their joint holding which shall, except where they otherwise direct, be delivered to
the joint holder whose name appears first in the Register in respect of the joint holding.



 


		8	The Issuer shall make no charge
to the holders for the registration of any holding of Notes or any transfer of Notes or for the issue of any Certificates or for the
delivery of Certificates at the principal place of business in Hong Kong of the Issuer to whom the request for registration, transfer
or delivery was delivered or by uninsured post to the address specified by the holder. If any holder entitled to receive a Certificate
wishes to have it delivered to him otherwise than at the principal place of business in Hong Kong of the Issuer, such delivery shall
be made upon his written request to the Issuer, at his risk and (except where sent by uninsured post to the address specified by the
holder) at his expense.



 


		9	The Issuer will within five Business
Days of a request to effect a transfer of a Note deliver at its principal place of business in Hong Kong to the transferee or despatch
by mail (at the risk of the transferee) to such address as the transferee may request, a new Certificate in respect of the Note or Notes
transferred. In the case of a transfer, conversion or redemption of fewer than all the Notes in respect of which a Certificate is issued,
a new Certificate in respect of the Notes not transferred, converted or redeemed will be so delivered to the holder of the Notes to its
address appearing on the register of holders of Notes.

of the Notes.

EXHIBIT E


PROVISIONS GOVERNING NOTEHOLDER MEETINGS


 


(A)            Poll


 


On a poll each Noteholder, proxy or representative
will have a vote in respect of each Note held or for which it is a proxy or representative. All votes will be conducted by poll.


 


(B)            Conduct
and Quorum


 


Any meeting of the Noteholders shall (subject
to the provisions of this Exhibit and Condition 14) be convened, conducted and held in all respects as near as possible in the same
way as shall be provided by the bye-laws for the time being of the Issuer with regard to general meetings of the Issuer provided that
no member of the Issuer not being a director or officer of the Issuer shall be entitled to notice thereof or to attend thereat unless
he is also a Noteholder and that the quorum at any such meeting shall be persons holding or representing by proxy or representative 50.1%
of the principal amount of the Notes for the time being outstanding. In the event of any conflict between the bye-laws of the Issuer for
the time being and Condition 14 and this Exhibit, the Conditions and this Exhibit shall prevail.


 


(C)            Proxies


 


Any Noteholder shall be permitted to appoint a
proxy to represent him at any Noteholders’ meeting held in accordance with this Instrument. A proxy need not be a Noteholder and
need not be a member of the Issuer. Any Noteholder wishing to appoint a proxy must deliver to the principal place of business of the Issuer
in Hong Kong a notice in writing signed by the Noteholder 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 stating that the Noteholder desires to appoint a proxy to represent
the Noteholder at the meeting. The notice shall state the name of the proxy and the notice will only be valid if delivered to the principal
place of business in Hong Kong of the Issuer at least 48 hours prior to the time appointed for the commencement of the meeting. A validly
appointed proxy shall have the right to vote on a resolution or act on his or its behalf in connection with any meeting or proposed meeting.
A holder of a Note which is a corporation may by delivering to the principal place of the Issuer in Hong Kong not later than 48 hours
before the time fixed for any meeting a resolution of its directors or other governing body in Hong Kong authorise any person to act as
its representative (a “representative”) in connection with any meeting or proposed meeting of Noteholders.


 


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 Noteholders
specified in such appointment, to be the holder of the Notes to which such appointment relates and the holder of the Note shall be deemed
for such purposes not to be the holder.


 


(D)            Adjournments


 


If within a quarter of an hour after the time
appointed for any meeting of Noteholders a quorum as set out in paragraph (B) above is not present the meeting shall stand adjourned
to such day (not being less than fourteen (14) or more than twenty-eight (28) days after the date of the meeting from which such adjournment
takes place) and time and place as the chairman of the meeting may determine and at the adjourned meeting the Noteholders present (whatever
the amount held or represented by them) shall form a quorum. Notice of an adjourned meeting shall be given in like manner as for the original
meeting and such notice shall state that the Noteholders present at such meeting whatever their number or the Notes held or represented
by them will constitute a quorum for all purposes.


 






    	 	Exhibit E

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 may not lawfully have been transacted at the meeting from which the adjournment took place.


 


The chairman shall be selected by the Issuer,
failing whom the Majority Noteholders shall be entitled to elect a chairman (who need not be a Noteholder).


 


The following shall be entitled to attend and vote at any meeting of
Noteholders


 


(a)            Noteholders,
proxies and representatives.

(E)            Written
Resolutions


 


A resolution in writing signed by or on behalf
of the Majority Noteholders 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 a resolution passed at a meeting of Noteholders 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
Noteholders.
