There shall not have been any adverse legislative or regulatory developments in the PRC following the signing of this Agreement, which in the Representatives’ sole judgment in good faith, would make it inadvisable or impractical to proceed with the public offering or the delivery of the Offered Securities at the Closing Date or the applicable Optional Closing Date, as the case may be, on the terms and in the manner contemplated in this Agreement.

The Company and the Depositary shall have executed and delivered the Deposit Agreement and, in the case of the Company, a side letter (the “Depositary Side Letter”) addressed to the Depositary, instructing the Depositary not to accept any shareholder’s deposit of Ordinary Shares in the Company’s American Depositary Receipt facility or issue any new ADSs to any shareholder or any third party unless consented to by the Company, and the Deposit Agreement shall be in full force and effect on the Closing Date and the applicable Option Closing Date.

To furnish to you a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which you reasonably object.

Not to take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

If the Time of Sale Prospectus is being used to solicit offers to buy the Offered Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

If, during such period after the first date of the public offering of the Offered Securities as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Company) to which the Offered Securities may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

To endeavor to qualify the Offered Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request.

To advise you promptly and confirming such advice in writing, of any request by the Commission for amendments or supplements to the Registration Statement, the ADS Registration Statement, the Exchange Act Registration Statement, any Time of Sale Prospectus, Prospectus or free writing prospectus or for additional information with respect thereto, or of notice of institution of proceedings for, or the entry of a stop order, suspending the effectiveness of the Registration Statement or the ADS Registration Statement and, if the Commission should enter a stop order suspending the effectiveness of the Registration Statement or the ADS Registration Statement, to use its best efforts to obtain the lifting or removal of such order as soon as possible.

To make generally available to the Company’s security holders and to you as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement, which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder (including Rule 158 under the Securities Act).

During the period when the Prospectus is required to be delivered under the Securities Act, to file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the rules and regulations of the Commission thereunder; during the five-year period after the date of this Agreement, to furnish to you and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to shareholders for such year; and to furnish to you (i) as soon as available, a copy of each report of the Company filed with or furnished to the Commission under the Exchange Act or mailed to shareholders, and (ii) from time to time, such other information concerning the Company as you may reasonably request; provided, however, that (i) in each case the Company will have no obligation to deliver such reports to the extent they are publicly available on the Company’s website or the Commission’s ▇▇▇▇▇ reporting system, and (ii) if the Company ceases to be subject to reporting obligations under the Exchange Act, it will have no obligation hereunder to deliver any reports.

To apply the net proceeds to the Company from the sale of the Offered Securities in the manner set forth under the heading “Use of Proceeds” in the Time of Sale Prospectus and to file such reports with the Commission with respect to the sale of the Offered Securities and the application of the proceeds therefrom as may be required by Rule 463 under the Securities Act; not to invest, or otherwise use the proceeds received by the Company from its sale of the Offered Securities in such a manner (i) as would require the Company or any of the Subsidiaries and Consolidated Affiliated Entities to register as an investment company under the 1940 Act, and (ii) that would result in the Company being not in compliance with any applicable laws, rules and regulations of the State Administration of Foreign Exchange of the PRC.

Not to, and to cause each of its Subsidiaries and Consolidated Affiliated Entities not to, take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Offered Securities.

To comply with the terms of the Deposit Agreement so that the Offered ADSs will be issued by the Depositary and delivered to each Underwriter’s participant account in DTC, pursuant to this Agreement on the Closing Date and each applicable Option Closing Date.

(i) Not to attempt to avoid any judgment in connection with this Agreement obtained by it, applied to it, or denied to it in a court of competent jurisdiction outside the Cayman Islands; (ii) following the consummation of the offering, to use its reasonable efforts to obtain and maintain all approvals required in the Cayman Islands to pay and remit outside the Cayman Islands all dividends declared by the Company and payable on the Ordinary Shares, if any; and (iii) to use its reasonable efforts to obtain and maintain all approvals, if any, required in the Cayman Islands for the Company to acquire sufficient foreign exchange for the payment of dividends and all other relevant purposes.

To comply with the PRC Overseas Investment and Listing Regulations, and to use its reasonable efforts to cause holders of its Ordinary Shares that are, or that are directly or indirectly owned or controlled by, Chinese residents or Chinese citizens, to comply with the PRC Overseas Investment and Listing Regulations applicable to them, including, without limitation, requesting each such shareholder to complete any registration and other procedures required under applicable PRC Overseas Investment and Listing Regulations (including any applicable rules and regulations of SAFE).

To use reasonable commercial efforts to rectify or cure any non-compliance, and maintain continuing compliance with PRC laws and regulations in all material respects.

To promptly notify you if the Company ceases to be an Emerging Growth Company at any time prior to the later of (a) completion of the distribution of the Offered Securities within the meaning of the Securities Act and (b) completion of the Restricted Period (as defined in this Section 6).

If at any time following the distribution of any Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Written Testing-the-Waters Communication, when considered together with the Time of Sale Prospectus, 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 Company will promptly notify you 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.

The Company will indemnify and hold harmless the Underwriters against any transaction, stamp, capital or other issuance, registration, documentary, transfer or other similar taxes or duties (other than taxes imposed on the net income of an Underwriter), including any interest and penalties, on the creation, allotment, issue and sale of the Offered Securities to the Underwriters and on the execution and delivery of, and the performance of the obligations (including the initial resale and delivery of the Offered Securities by the Underwriters) under, this Agreement or the Deposit Agreement and on bringing any such document within any jurisdiction. All payments to be made by the Company to the Underwriters hereunder shall be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made, except to the extent of taxes that would not have been imposed but for (i) the recipient’s being a resident of the jurisdiction imposing such taxes, having a permanent establishment therein, or having a similar connection with such jurisdiction (in each case, other than as a result of the transactions contemplated by this Agreement) or (ii) the recipient’s failure to comply with a request from the Company to provide any documentation or certification that the recipient is legally able to provide (and can do so without undue hardship) concerning the recipient’s nationality, residence, identity or connection with the applicable taxing jurisdiction, and that is required as a precondition to exemption from, or reduction in the rate of, the withholding or deduction of such taxes. In addition, all sums payable to an Underwriter hereunder shall be considered exclusive of any value added or similar taxes. Where the Company is obliged to pay value added or similar tax on any amount payable hereunder to an Underwriter, the Company shall, in addition to the sum payable hereunder, pay an amount equal to any applicable value added or similar tax.

The Company, without the prior written consent of the Representatives on behalf of the Underwriters, will not, during the period ending 180 days after the date of the Prospectus (the “Restricted Period”), (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Ordinary Shares or American Depositary Shares beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) or any other securities so owned convertible into or exercisable or exchangeable for Ordinary Shares or American Depositary Shares or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Ordinary Shares or American Depositary Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Ordinary Shares, American Depositary Shares or such other securities, in cash or otherwise, (iii) file or submit any registration statement with the Commission relating to the offering of any Ordinary Shares, American Depositary Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares or American Depositary Shares, or (iv) publicly disclose the intention to do any of the foregoing.

The Company agrees (1) to cause each option holder who has not entered into a Lock-up Letter contemplated hereunder to be subject to and comply with all of the restrictions set forth in such Lock-up Letter, (2) to instruct its share registrar not to give effect to any share transfers directly or indirectly by any shareholder during the Restricted Period, and (3) to enter into the Depositary Side Letter with the Depositary, and not to release the Depositary from any of its obligations set forth in, or otherwise amend, terminate or fail to enforce, the Depositary Side Letter or consent to any deposit during the Restricted Period unless with the prior written consent of the Representatives on behalf of the Underwriters.

If the Representatives, in their sole discretion, agree to release or waive the restrictions set forth in a Lock-up Letter for an officer or director of the Company and provides the Company with notice of the impending release or waiver at least three business days before the effective date of the release or waiver, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit B hereto through a major news service at least two business days before the effective date of the release or waiver.

EXPENSES.

COVENANTS OF THE UNDERWRITERS. Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of such Underwriter.

INDEMNITY AND CONTRIBUTION.

The Company agrees to indemnify and hold harmless each Underwriter, each director, officer, employee, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the ADS Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or any Written Testing-the-Waters Communication or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and shall reimburse each Underwriter and each such director, officer, employee, controlling person or affiliate promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee, controlling person or affiliate in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon 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 Underwriter Information (as defined below).

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either 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, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus or the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter consists of the addresses of the Representatives appearing in the [ninth] paragraph under the caption “Underwriting” (the “Underwriter Information”).

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such directors, officers, employees, control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it 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 such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party 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 party.

To the extent the indemnification provided for in Section 9(a) or 9(b), is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Offered Securities or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand 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 on the one hand and the Underwriters on the other hand in connection with the offering of the Offered Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Offered Securities (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Offered Securities. The relative fault of the Company on the one hand and the Underwriters on the other hand 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 or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Offered ADSs they have purchased hereunder, and not joint.

The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if 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 Section 9(c). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(c) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, 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 Offered Securities 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 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 party at law or in equity.

The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, its directors, officers or employees, any person controlling any Underwriter or any affiliate of any Underwriter, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Offered Securities.

TERMINATION. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT, NASDAQ, the Hong Kong Stock Exchange or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States, the PRC or the Cayman Islands shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by United States Federal, New York State, PRC or Cayman Islands authorities or with respect to Clearstream or Euroclear systems in Europe, or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Offered Securities on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus or to enforce contracts for the sale of the ADSs.

EFFECTIVENESS; DEFAULTING UNDERWRITERS. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

SUBMISSION TO JURISDICTION; APPOINTMENT OF AGENT FOR SERVICE. The Company hereby irrevocably submits to the exclusive jurisdiction of the New York Courts in any suit or proceeding arising out of or relating to this Agreement, the Deposit Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement, the ADS Registration Statement, the offering of the Offered Securities, or any transactions contemplated hereby. The Company and each of the Company’s Subsidiaries and Consolidated Affiliated Entities irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement, the Deposit Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement, the ADS Registration Statement, the offering of the Offered Securities, or any transactions contemplated hereby in the New York Courts, and irrevocably and unconditionally waives and agrees 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 irrevocably appoints Cogency Global Inc. as its respective authorized agent in the Borough of Manhattan in The City of New York upon which process may be served in any such suit or proceeding, and agree that service of process in any manner permitted by applicable law upon such agent shall be deemed in every respect effective service of process in any manner permitted by applicable law upon the Company, as the case may be, in any such suit or proceeding. The Company further agrees 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.

JUDGMENT CURRENCY. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company pursuant to this Agreement with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company agrees as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the united states dollars so purchased are greater than the sum originally due to such underwriter or controlling person hereunder, such underwriter or controlling person agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such underwriter or controlling person hereunder.
