3.2

New Share. “New Share” refers to any Equity Securities of the Company (whether or not it is now an authorized share capital) and rights, options or warrants of any type of securities that may be purchased or converted or exchanged for Equity Securities of the Company. While the term “New Share” shall not include:

3.3	Procedure.

(a)

Priority Subscription Notice. If the Company plans to issue New Shares (whether through a single transaction or a series of related transactions), it shall give each Investor a written notice of its intention to issue such New Shares (the “Priority Subscription Notice”) describing the number, type, price of the New Shares and the general terms and conditions under which the Company intends to issue such New Shares. Each Investor may, within five (5) Working Days (the “Priority Subscription Period”) from the date of receipt of the Priority Subscription Notice, agree in writing to purchase the amount of New Shares to be issued at the prices and terms and conditions set out in the Priority Subscription Notice by giving a written notice to the Company (the “Notice of Exercising Right of First Refusal”) stating the number of New Shares to be purchased. If any investor fails to give a Notice of Exercising Right of First Refusal during the Priority Subscription Period, such Investor shall be deemed to have waived his Right of First Refusal. The Board of Directors of the Company shall not pass any resolution enabling the Company to issue any New Shares under the Right of First Refusal to any third person that have not been exercised or waived by the Investors in accordance with the provisions of this Clause 3. The maximum amount of New Shares that any investor is entitled to subscribe for is: New Shares x (the number of Ordinary Shares held by the Investor at the time of the Company’s Priority Subscription Notice ÷ the sum of all Ordinary Shares issued at the time of the Company’s Priority Subscription Notice).

3.4

Failure to Exercise. Upon expiration of the Priority Subscription Period, and in the case that the New Shares are not fully subscribed by each Investor through the Right of First Refusal, the Company shall, within ninety (90) days after the expiration of the Priority Subscription Period, sell the New Shares described in the Priority Subscription Notice (in respect of the unexercised portion of the Right of First Refusal) at a price equal to or higher than the price stated in the Priority Subscription Notice, or for non-price terms, on terms no more favorable than those set forth in the Priority Subscription Notice. If the Company fails to complete the issue and sale of the New Shares within ninety (90) days after the expiration of the Priority Subscription Period, or the Company intends to issue and sell the New Shares on terms more favorable than those set out in the Priority Subscription Notice, the Company shall not issue or sell any New Shares thereafter without resending the Priority Subscription Notice to the Investors and the Investors’ exercise of the Right of First Refusal under this Clause 3.

3.5	Termination. The Right of First Refusal of each Investor shall be terminated at the time of the completion of the Qualified Public Offering and delivery.

4.	TRANSFER RESTRICTIONS

4.1	Preemptive Right.

(a)

Notice of Transfer. If (i) a Disposing Shareholder intends to Transfer directly or indirectly any of his Equity Securities to one or more third parties, or (ii) at any time any Equity Securities held by a Disposing Shareholder are involuntarily transferred, the Disposing Shareholder shall give notice in writing (the “Notice of Transfer”) to the company to whom the Transfer is made and to the Investors. Such Notice of Transfer shall include (A) a description of the Equity Securities to be transferred (the “Sold Shares”), (B) the identity of the potential transferee, and (C) the consideration for the proposed Transfer and the principal terms and conditions upon which it is based. The price of each Sold Share shall not be lower than the Price Per Share for Investors. The Notice of Transfer shall prove that the Disposing Shareholder has received a firm offer from the potential assignee and is satisfied in good faith that it may enter into a binding agreement on the Transfer in accordance with the terms of the Notice of Transfer. The Notice of Transfer shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer.

(b)

Exercise of Preemptive Right.

(i)

Each Investor shall have the right to give written notice (the “Purchase Notice”) to the Disposing Shareholders within five (5) Working Days (the “Preemptive Period”) of receipt of the Notice of Transfer to give priority to purchase the Sold Shares on the terms and conditions set forth in the Notice of Transfer (subject to the provisions of Clause 4.1(b)(ii) below) (the “Preemptive Right”). The Purchase Notice shall state the amount of Sold Shares to be purchased by each Investor.

(ii)

The number of Sold Shares available for each Investor: Where each Investor claims to exercise the Preemptive Right, the respective purchase proportion shall be determined through consultation. If no agreement can be reached, the Preemptive Right shall be exercised in proportion to the total number of shares held by the investors who claim the Preemptive Right at the time of transfer, which shall be equal to the total number of shares held by the Investors who claim the Preemptive Right at that time.

(iii)

If an ongoing Transfer arises as a result of enforcement of law or another involuntary transfer (including a transfer arising from death, divorce, separation or insolvency), the price per share should be the higher of the following: (A) the original purchase price paid by the Disposing Shareholder for the Sold Shares (subject to such adjustments as may be appropriate in the case of share splits, dividends distribution, mergers and the like), but not less than the nominal value, or (B) the fair market value (not less than the nominal value) of the Sold Shares, as determined by the Board of Directors, taking into account such factors as the Company’s current income and future prospects and reflecting the current value of the Shares, and determined by the Company within thirty (30) Working Days of receipt of the Notice of Transfer. If the Disposing Shareholder or the executor of the Disposing Shareholder disagrees with the valuation determined by the Board of Directors, then the Disposing Shareholder or the executor of the Disposing Shareholder shall have the right to entrust an independent appraiser agreed by the Company and the Disposing Shareholder or the executor of the Disposing Shareholder to determine the valuation, and the appraiser’s expenses shall be shared equally between the Company and the Disposing Shareholder or the estate of the Disposing Shareholder.

4.2

Co-Sale Rights. If any investor fails to exercise the Preemptive Right mentioned in the preceding paragraph, within ten (10) Working Days after the expiration of the Preemptive Period (the “Co-Sale Period”), such Investor may give a written notice (the “Co-Sale Notice”) to the Disposing Shareholder and the Company requiring the Investor’s shares in the Company to be sold to a potential transferee of the Sold Shares (the “Co-Sale Rights”) in accordance with the sale price of the Sold Shares and other terms and conditions set out in the Notice of transfer. Investor’s Sellable Shares = (the percentage of Sold Shares of Disposing Shareholder to all of their shares * the number of shares held by the Investor). If a potential transferee of Sold Shares refuses to purchase any number of shares to be sold by the investor, or the potential transferee fails to complete the purchase of the shares to be sold by the Investor before or at the same time as the purchase of the Sold Shares is completed, the Disposing Shareholder shall not sell any of the Sold Shares to the potential transferee unless the Disposing Shareholder completes the purchase of the Investor’s shares to be sold prior to or at the same time as the sale price (not less than the nominal value) and other terms and conditions set out in the Notice of Transfer.

4.3

Not Exercising Rights. If Investors fail to exercise the Preemptive Right under Clause 4.2 and the Co-Sale Right under Clause 4.3, the Disposing Shareholder shall sell any remaining Sold Shares to the third party transferee identified in the Notice of Transfer within ninety (90) days after the expiration of the Co-Sale Period, on terms and conditions (including the Purchase Price) not favorable to the Purchaser as set forth in the Notice of Transfer. As a condition for the effective Transfer of the Sold Share, the third party transferee shall provide the Company and all Shareholders of the Company with written consent to be bound by and to comply with this Agreement, including but not limited to all provisions of this Clause 4, as if the transferee were a Disposing Shareholder in this Agreement and to comply with the terms of the transferee under which the Equity Securities are issued. If the Disposing Shareholder fails to complete the sale or disposal of the Sold Shares within ninety (90) days after the expiration of the Co-Sale Period, or the Company proposes to sell the Sold Shares on more favorable terms than those set out in the Notice of Transfer, or the Company proposes to sell the Sold Shares to a party other than a third party transferee as identified in the Notice of Transfer, the Disposing Shareholders shall not sell any Sold Shares until the Investors have re-exercised their Preemptive Rights and Co-Sale Rights under this Clause 4. Moreover, whether any investor exercises a Preemptive Right or a Co-Sale Right over the Sold Shares of the Disposing Shareholder shall not adversely affect the subsequent purchase of Equity Securities by the Investor from any Disposing Shareholder. Any subsequent Transfer of any Sold Shares proposed by the Disposing Shareholders shall again be subject to the Preemption and Co-Sale Rights of the Investors and the relevant Disposing Shareholders shall be required to comply with the procedures set out in this Clause 4.

4.4

Legend.

(a)

Each certificate issued to each Existing Major Shareholder representing the Ordinary Share shall endorse the following legend:

“The sale, pledge, mortgage or transfer of the securities represented by this Certificate is subject to specific restrictions on the transfer under the Shareholders’ Agreement, a copy of which may be obtained by written request to the Secretary of the Company.”

(b)

The Parties agree that the Company may direct its Transfer agent to impose transfer restrictions on the Shares represented by the certificates of the legend referred to in Clause 4.5 (a) above for the purpose of enforcing the terms of this Agreement, and the Company agrees to do so forthwith. The legend shall be removed at the termination of the provisions of this Clause 4.
