In addition, the Company proposes to issue and sell, at the option of the Underwriters, up to an additional 225,000 ADSs of the Company and the Selling Shareholders severally propose to sell, at the option of the Underwriters, up to an additional 1,425,000 ADSs of the Company (collectively, the “Option Shares”).

The Company and the Selling Shareholders hereby confirm their respective agreements with the several Underwriters concerning the purchase and sale of the Shares, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), an “automatic shelf registration statement” as defined by Rule 405 of the Securities Act on Form F-3 (File No. 333- 222659), including a base prospectus (the “Base Prospectus”), relating to the Ordinary Shares underlying the Shares (the “Underlying Ordinary Shares”) and other securities that may be issued or sold from time to time by the Company and certain shareholders of the Company in accordance with Rule 415 of the Securities Act and such amendments thereof as may have been required to the date of this underwriting agreement (this “Agreement”). The term “Registration Statement” as used in this Agreement means the initial registration statement, at the time it became effective and as supplemented or amended, including the information, if any, contained in any preliminary prospectus pursuant to Rule 424(b) and Rule 430A, 430B or 430C under the Securities Act; and as used herein, the term “Preliminary Prospectus” means the Base Prospectus and any preliminary prospectus supplement used or filed with the Commission pursuant to Rule 424(b), in the form provided to the Underwriters by the Company for use in connection with the offering of the Shares, and the term “Prospectus” means the Base Prospectus, any Preliminary Prospectus and any amendments or further supplements to such prospectus, and including without limitation the final prospectus supplement (the “Prospectus Supplement”) filed pursuant to and within the time limits described in Rule 424(b) with the Commission in connection with the proposed sale of the Shares contemplated by this Agreement. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 6 of Form F-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex A, the “Pricing Disclosure Package”): a Preliminary Prospectus dated January 23, 2018 and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

If any Option Shares are to be purchased, the number of Option Shares to be purchased by each Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 12 hereof) bears to the aggregate number of Underwritten Shares being purchased from the Company and the Selling Shareholders by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representatives in their sole discretion shall make.

Based on the Company’s current projections of its income and assets, the value of its assets and the value of its outstanding Ordinary Shares and ADSs, after giving effect to the offering and sale of the Shares and the application of the proceeds thereof as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, the Company does not expect to be classified as a passive foreign investment company as defined in Section 1297 of the United States Internal Revenue Code of 1986, as amended, for the taxable year 2017 or in the foreseeable future.

The Company agrees to indemnify and hold harmless each Underwriter and its partners, members and affiliates, and their respective directors, officers and agents, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any loss, claim, damage, liability, litigation, investigation, suit, action or proceeding (whether or not such Indemnified Person (as defined below) is a party thereto), whether commenced or threatened, and in connection with the enforcement of this provision with respect to any of the above, in each case, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, any Written Testing-the-Waters Communication, any road show as defined in Rule 433(h) under the Securities Act (a “road show”) or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which

they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(b) Indemnification of the Underwriters by the Selling Shareholders. Each Selling Shareholder, severally and not jointly, in proportion to the number of Shares to be sold by such Selling Shareholder hereunder, agrees to indemnify and hold harmless each Underwriter and its partners, members and affiliates, and their respective directors, officers and agents, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with such Selling Shareholder’s Selling Shareholder Information, in each case except insofar as such losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or the Pricing Disclosure Package, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(c) Indemnification of the Company and the Selling Shareholders. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of the Selling Shareholders to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication, any road show or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus under the caption “Underwriting”: (i) their respective names appearing in the first paragraph, (ii) the concession and reallowance figure appearing in the fourth paragraph, (iii) their respective names and addresses in the fifth paragraph, (iv) the tenth paragraph, (v) the first, second, fifth and sixth sentences in the eighteenth paragraph and (vi) the first sentence in the nineteenth paragraph.

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the

preceding paragraphs of this Section 9, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 9. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person will be entitled to participate therein and, shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Shareholders shall be designated in writing by the Selling Shareholders. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and

substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(e) Contribution. If the indemnification provided for in paragraphs (a), (b) and (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company or the Selling Shareholders, as the case may be, on the one hand, and the Underwriters on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company or the Selling Shareholders, as the case may be, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company or the Selling Shareholders, as the case may be, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company or the Selling Shareholders, as the case may be, from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Company or the Selling Shareholders, as the case may be, on the one hand, and the Underwriters on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, by the Selling Shareholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (e) above were determined by pro rata allocation (even if the Selling Shareholders or the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in this paragraph and paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of paragraph (e) above, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this paragraph and paragraph (e) above are several in proportion to their respective purchase obligations hereunder and not joint.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

10. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

11. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company and the Selling Shareholders, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Shares, prior to an Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or The Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by United States federal, Xxx Xxxx Xxxxx, Xxxxxx Xxxxxxx, Xxxx Xxxx or PRC authorities; (iv) there is any major disruption of settlements of securities, payment, or clearance services in the United States, Cayman Islands, Hong Kong or the PRC; or (v) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, or any change in U.S., PRC, Hong Kong, Cayman Islands or international financial, political or economic conditions or currency exchange rates or exchange controls, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or an Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus, or to enforce contracts for the sale of Shares.

12. Defaulting Underwriter.

(a) If, on the Closing Date or an Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company and the Selling Shareholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company and the Selling Shareholders shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or such Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 12, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company and the Selling Shareholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or an Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company and the Selling Shareholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Shareholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or an Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company and the Selling Shareholders shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on such Additional Closing Date, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 12 shall be without liability on the part of the Company or the Selling Shareholders, except that each of the Company and the Selling Shareholders will continue to be liable for the payment of expenses as set forth in Section 13 hereof and except that the provisions of Section 9 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Selling Shareholders or any non-defaulting Underwriter for damages caused by its default.

13. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Pricing Disclosure Package and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of this Agreement and the Deposit Agreement; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum or Canadian wrapper (including the related fees and expenses of counsel for the Underwriters), provided that the reimbursement obligation for such fees and expenses does not exceed $5,000; (vi) the cost of issuing Shares; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees incurred by the Company in connection with any filing with, and clearance of the offering by, FINRA, and the fees and disbursements of counsel for the Underwriters in connection with, any required review

by the FINRA of the terms of the sale of the Shares, provided that the reimbursement obligation for any such fees and expenses representing fees and expenses of counsel for the Underwriters shall not exceed $30,000; (ix) all travel and lodging expenses of the officers, directors and other members of the Company in connection with any “road show” presentation or testing-the-waters presentation to potential investor, to the extent incurred by the Underwriters on behalf of such persons, and the cost of chartering aircraft for the Company and Underwriters in connection with the roadshow or testing-the-waters process; (x) any and all expenses and application fees related to the listing of the Shares on the NASDAQ; and (xi) the fees and expenses of the Selling Shareholders’ counsel It is understood, however, that except as provided in clause (ix) in this Section 13(a) and Section 13(b), the Underwriters will pay expenses incurred by the Underwriters in connection with any “road show” presentation or testing-the-waters presentation; and except as provided in Section 9, clauses (v) and (viii) in this Section 13(a) and Section 13(b), the Underwriters will pay fees and disbursements of their counsel.

(b) If the purchase of the Shares by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 12 hereof (including without limitation the Selling Shareholders’ failure to tender the Shares for delivery to the Underwriters), the Company agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

14. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein and the affiliates of each Underwriter referred to in Section 9 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Shares from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

15. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Selling Shareholders and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Selling Shareholders or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Selling Shareholders or the Underwriters.

address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

18. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) No Other Relationship. The Representatives have been retained solely to act as underwriters in connection with the sale of the Shares and that no fiduciary, advisory or agency relationship between the Company and the Selling Shareholders, on the one hand, and the Representatives, on the other hand, have been created in respect of any of the transactions contemplated by this Agreement or the Prospectus, irrespective of whether the Representatives have advised or is advising the Company or the Selling Shareholders on other matters.

(b) Arm’s Length Negotiations. The Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Selling Shareholders with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Selling Shareholders or any other person. Additionally, the Company and each of the Selling Shareholders are capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement.

(d) Waiver. The Company and each of the Selling Shareholders waive, to the fullest extent permitted by law, any claims it may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representatives shall have no liability (whether direct or indirect) to the Company and the Selling Shareholders in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company and the Selling Shareholders, including their respective stockholders, employees or creditors.

The Company and each Selling Shareholder hereby submit to the non-exclusive jurisdiction of the federal and state courts in the Borough of Manhattan in the City of New York (the “New York Courts”) in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company and each Selling Shareholder irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in the New York Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

The Company and each Selling Shareholder further agree to take any and all action as may be necessary to maintain such designation and appointment of such agent in full force and effect for a period of seven years from the date of this Agreement. The Company and each Selling Shareholder irrevocably waive, to the fullest extent permitted by law, any and all rights to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. To the extent that the Company or a Selling Shareholder, as the case may be, has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property and assets (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution, set-off or otherwise), the Company and such Selling Shareholder hereby irrevocably waive, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

(d) Judgment Currency. The Company and each Selling Shareholder agree to indemnify each Underwriter, its directors, officers, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “judgment currency”) other than U.S. dollars and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order, and (ii) the rate of exchange at which such indemnified person is able to purchase U.S. dollars with the amount of the judgment currency actually received by the indemnified person. The foregoing indemnity shall constitute a separate and independent obligation of the Company and each Selling Shareholder and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

(e) Waiver of Jury Trial. Each of the parties hereto hereby waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement.

To Whom It May Concern:

In reliance on Section 5(d) of the Securities Act of 1933, as amended (the “Act”), GDS Holdings Limited (the “Issuer”) hereby authorizes RBC Capital Markets, LLC, Citigroup Global Markets Inc., X.X. Xxxxxx Securities LLC (“X.X. Xxxxxx”), and their respective affiliates and their respective employees (the “Authorized Underwriters”), to engage on behalf of the Issuer in oral and written communications with potential investors that are “qualified institutional buyers”, as defined in Rule 144A under the Act, or institutions that are “accredited investors”, as defined in Regulation D under the Act, to determine whether such investors might have an interest in the Issuer’s contemplated follow-on offering (“Testing-the-Waters Communications”). A “Written Testing-the Waters Communication” means any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Act. The Issuer has advised the Authorized Underwriters that it does not intend to provide or authorize any written communications to potential investors other than communications that are solely administrative in nature.

The Issuer represents that it is an “emerging growth company” as defined in Section 2(a)(19) of the Act (“Emerging Growth Company”) and agrees to promptly notify the Authorized Underwriters in writing if the Issuer hereafter ceases to be an Emerging Growth Company while this authorization is in effect. If at any time following the distribution of any Written Testing-the-Waters Communication there occurs an event or development as a result of which such Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the

circumstances existing at that subsequent time, not misleading, the Issuer will promptly notify the Authorized Underwriters and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

Nothing in this authorization is intended to limit or otherwise affect the ability of the Authorized Underwriters, to engage in communications in which they could otherwise lawfully engage in the absence of this authorization, including, without limitation, any written communication containing only one or more of the statements specified under Rule 134(a) under the Act. This authorization shall remain in effect until the Issuer has provided to the Authorized Underwriters a written notice revoking this authorization. All notices as described herein shall be sent to RBC Capital Markets, LLC by e-mail to the attention to Xxxx Xxxxxxxxx at xxxx.xxxxxxxxx@xxxxx.xxx, with a copy to Xxxxx Xxxxxxxx at xxxxx.xxxxxxxx@xxxxx.xxx and to X.X. Xxxxxx by email to the attention of Xxxxx Xxxxxx at xxxxx.xxxxxx@xxxxxxxx.xxx, with a copy to Xxxxxx Xxxxxxx at xxxxxx.x.xxxxxxx@xxxxxxxx.xxx.

In addition, nothing in this Letter Agreement shall prohibit the undersigned from transferring the Lock-Up Shares pursuant to Rule 10b5-1 under the Exchange Act, provided that such plan was established prior to the execution of this Lock-Up Agreement; provided further that to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding such transfer, such announcement or filing shall include a statement to the effect that such transfer was effected pursuant to a trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act. The undersigned hereby also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Lock-Up Shares unless such transfer is in compliance with the foregoing restrictions.

The undersigned hereby agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Letter Agreement during the period from the date of this Letter Agreement to the expiration of the Restricted Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written consent from the Company.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.
