3. EXERCISE OF OPTION. 
  

	3.1	From time to time, and on more than one occasion, prior to the earlier to occur of (i) the termination hereof in accordance with the provisions of this Agreement,
or (ii) the Expiration Date (as set forth above), the Optionee may give written notice to the Company of his election to purchase some, in which case, a minimum of 200 Option Shares, or all of the Option Shares for which this Option may be
exercised at the time of such notice. Such written notice shall specify the number of Option Shares to be purchased and shall be accompanied by (i) the delivery of an executed Exercise Agreement in substantially the form attached hereto as
Exhibit A or such other form as the Company may require from time to time (the “Exercise Agreement”); (ii) the payment therefor in cash or, at the discretion of the Company, such other method of payment acceptable to the
Company, and (iii) such agreement, statement or other evidence as the Company may require in order to satisfy itself that the issuance of the Option Shares being purchased pursuant to such exercise and any subsequent resale thereof will be in
compliance with applicable laws and regulations, including without limitation all applicable U.S. Federal and state securities laws and regulations. 

  

	3.2	The Company reserves the right to withhold the exercise of the Option for reasons including but not limited to the Optionee’s failure to comply with the applicable
rules and regulations of the Company, Gushan, NYSE or the U.S. Securities And Exchange Commission; the Optionee’s breach of his employment agreement; the Optionee’s unwillingness or failure to follow Company directives; and the
Optionee’s failure to perform his duties and responsibilities, as applicable. 

  

	3.3	Exercisability of the Option upon and after termination of the Optionee’s office with the Company shall be in accordance with the following:


  

	 	(i)	if the Optionee’s office with the Company terminates due to the death of the Optionee, no exercise of the Option may occur after the expiration of the one-year
period to follow such termination or, if earlier, the Expiration Date, 









	 	(ii)	if the Optionee’s office with the Company is terminated by the Company for cause, the Option shall thereupon cease to be exercisable and shall be forfeited
forthwith, 

  

	 	(iii)	in the case where the Optionee has served as a director of the Company for less than three years beginning from the Date of Grant, if (a) the Optionee’s
office with the Company is terminated by the Company (other than for cause), or (b) the Optionee resigns his office with the Company, no exercise of the Option may occur after the expiration of the three-month period to follow such termination
or resignation or, if earlier, the Expiration Date, 

  

	 	(iv)	in the case where the Optionee has served as a director of the Company continuously for three years or more beginning from the Date of Grant, if (a) the
Optionee’s office with the Company is terminated by the Company (other than for cause), or (b) the Optionee resigns his office with the Company, no exercise of the Option may occur after the Expiration Date. 


 

	3.4	Notwithstanding any other provision hereof, the Option shall not be exercised unless all necessary regulatory, corporate or other approvals, as applicable, have been
received. 

 4. EXPIRATION DATE OF OPTION. 
 Notwithstanding anything herein to the contrary, unless earlier exercised, forfeited or otherwise terminated, the Option shall expire in its entirety upon the Expiration Date. 

5. TRANSFERABILITY. 
 This Agreement is
personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or by the laws of descent and distribution, and is exercisable, during the Optionee’s lifetime, only by the
Optionee. The terms of this Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
 6.
RIGHT OF FIRST REFUSAL. 
 The Company shall have a right of first refusal, as set forth below, to purchase the Option Shares acquired
upon exercise of the Option before the Option Shares (or any interest in them) can be validly transferred to any other person or entity. 
  

	6.1	Notice of intent to sell. Before there can be a valid sale or transfer of any Option Shares (or any interest in them) by the Optionee, the Optionee shall first
give notice in writing to the Company, mailed or delivered in accordance with the provisions of Section 8.1, of his or her intention to sell or transfer such Shares (the “Option Notice”). 


The Option Notice shall specify the identity of the proposed transferee, the number of Option Shares to be sold or transferred to the
transferee, the price per Option Share and the terms upon which the Optionee intends to make such sale or transfer. If the payment terms for the Option Shares described in the Option Notice differ from delivery of cash or a check at closing, the
Company shall have the option, as set forth herein, of purchasing the Option Shares for cash (or a cash equivalent) at closing in an amount which the Company determines is a fair value equivalent of that payment. The determination of a fair value
equivalent shall be made in the Company’s best judgment and such determination shall be mailed or delivered to the Optionee (the “Company’s Notice”) within ten (10) days of its receipt of the Option Notice. Should the
Optionee disagree with the Company’s determination of a fair value equivalent, he or she shall have the right (the “Retraction Right”) to retract the proposed sale or transfer to a third party and the offer of Option Shares to
the Company pursuant to the Option Notice (such retraction to be made in writing and mailed or delivered in accordance with the provisions of Section 8.1). If the Optionee again proposes to sell or transfer the Option Shares, the Optionee shall
again offer such Option Shares to the Company pursuant to the terms of this Section 6 prior to any sale or transfer. 
  

	6.2	Option to purchase. Subject to the Optionee’s Retraction Right, during the 60-day period commencing upon receipt of the Option Notice by the Company (the
“Option Period”), the Company shall have an option to purchase any or all of the Option Shares specified in the Option Notice at the price offered therein (the “Right of First Refusal”). 









	6.3	Purchase of shares. Not more than thirty (30) days after receipt of the Option Notice, the Company shall give written notice to the Optionee desiring to
sell or transfer Option Shares of the number of such Option Shares to be purchased (or, if no Option Shares are to be purchased, stating such fact) by the Company pursuant to the terms of this Section 6 (the “Purchase Notice”).
Purchases pursuant to this Section 6 shall be consummated within thirty (30) days after delivery of the Purchase Notice to the Optionee, but in no event later than the expiration of the Option Period. The purchase price shall be paid at
the closing in cash, by check, or, if the payment terms set forth in the Option Notice differ from payment in cash or by check at closing, in accordance with the payment terms set forth in the Option Notice (or payment of the amount set forth in the
Company’s Notice in cash, or by check). The purchase price shall be paid against surrender by the Optionee of a share certificate evidencing the number of Option Shares specified in the Option Notice, with duly endorsed share transfer forms.


  

	6.4	Ability to sell unpurchased shares. Unless all of the Option Shares referred to in the Option Notice are to be purchased as indicated in the Purchase Notice, the
Optionee may dispose of any Option Shares referred to in the Option Notice that are not to be purchased by the Company to the person or persons specified in the Option Notice during a period of twenty (20) days commencing upon his receipt of
the Purchase Notice; provided, however, that he shall not sell or transfer such Option Shares (a) at a lower price or on terms more favorable to the Optionee or transferee than those specified in the Option Notice, and (b) to a
person other than the person or persons specified in the Option Notice; and provided further that such transfer is consistent with the other provisions and limitations of this Agreement and the Exercise Agreement. If the transfer is not
consummated within such twenty (20) day period, the Optionee shall again offer such Option Shares to the Company pursuant to the terms of this Section 6 prior to any sale or transfer to the same or any other person.


  

	6.5	Assignment. Notwithstanding anything to the contrary, the Company may assign any or all of its rights under this Section 6 to one or more shareholders of
the Company. 

  

	6.6	No shareholder rights following exercise of right of first refusal. If the Optionee ceases to hold office in the Company and holds Option Shares as to which the
Right of First Refusal has been exercised, the Optionee shall be entitled to the value of such Option Shares in accordance with the provisions of this Section 6, but (unless otherwise required by law) shall no longer be entitled to
participation in the Company or other rights as a shareholder with respect to such Option Shares. To the maximum extent permitted by law, the Optionee’s rights following the exercise of the Right of First Refusal shall, with respect to the
Right of First Refusal exercised and the Option Shares covered thereby, be solely the rights that he has as a general creditor of the Company to receive payment of the amount specified in this Section 6. 


7. NO GUARANTEE OF CONTINUED SERVICE. 

OPTIONEE ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED
PROMISE OF CONTINUED ENGAGEMENT AS A DIRECTOR OF THE COMPANY FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH THE OPTIONEE’S RIGHT OR THE COMPANY’S RIGHT TO TERMINATE THE OPTIONEE’S ENGAGEMENT AS A DIRECTOR AT ANY TIME, WITH OR
WITHOUT CAUSE (SUBJECT TO THE TERMS OF ANY EMPLOYMENT OR OTHER AGREEMENT WITH THE OPTIONEE, IF ANY). 
 8. MISCELLANEOUS  

 

	8.1	In the event of any capitalisation issue, rights issue, open offer, sub-division, consolidation of shares, or reduction of capital of the Company, such corresponding
alterations (if any) shall be made (except on an issue of securities of the Company as consideration in a transaction which shall not be regarded as a circumstance requiring alteration or adjustment) in (i) the number of Option Shares that may
be issued subject to the unexercised portion of the Option; and/or (ii) the Option Exercise Price, as the board of directors of the Company shall determine to be appropriate, fair and reasonable. 


 

	8.2	The Option Shares to be allotted and issued upon the exercise of the Option shall not carry voting rights until completion of the registration of the Optionee as the
holder thereof. Subject as aforesaid, the Option Shares to be allotted and issued upon the exercise of the Option shall be subject to all the provisions of the constitutional documents of the Company for the time being in force and shall rank pari
passu in all respects with and shall have the same voting, dividend, transfer and other rights, including those arising on liquidation of the Company as attached to all other fully-paid ordinary shares of the Company in issue on the date of issue,
in particular but without prejudice to the generality of the foregoing, in respect of voting, transfer and other rights including those arising on a liquidation of the Company and rights in respect of any dividend or other distributions paid or made
on or after the date of issue. 









	8.3	Notice hereunder shall be mailed or delivered to the Company, and shall be delivered to the Optionee in person or mailed or delivered to the Optionee at the addresses
set forth below, respectively, or in either case at such other address as one party may subsequently furnish to the other party in writing. 

  

	8.4	By the parties’ signatures below, the parties agree that the Option is granted under and governed by the terms and conditions of this Agreement and the attached
form of the Exercise Agreement. The Optionee has reviewed this Agreement and the attached form of the Exercise Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Agreement and fully
understands all provisions of this Agreement and the attached form of the Exercise Agreement. 

  

	8.5	This Agreement shall be governed by the laws of the British Virgin Islands, without reference to principles of conflict of laws. 


 

	8.6	This Agreement (together with the form of Exercise Agreement attached hereto) constitutes the entire agreement of the parties and supersedes all prior undertakings and
agreements with respect to the subject matter hereof. This Agreement and the Exercise Agreement may be amended. Such amendment must be in writing and signed by the parties hereto. The Company may, however, unilaterally waive any provision hereof or
of the Exercise Agreement in writing to the extent such waiver does not adversely affect the interests of the Optionee, but no such waiver shall operate as or be construed to be a subsequent waiver of the same provision or a waiver of any other
provision hereof. 

  

	8.7	This Agreement may be signed in various counterparts, which together shall constitute one and the same document.
