if such action or failure to act by the Sublicensee would have constituted a breach of this Agreement if such action or failure were committed by FOSUN. Without limiting the foregoing, FOSUN shall obtain rights and licenses from its Affiliates (but only to the extent that such Affiliates are FOSUN’s Sublicensees hereunder) and Sublicensees as necessary to enable FOSUN to grant to Ardelyx rights and licenses under Patents and Know-How Controlled by such Affiliates and Sublicensees to the same extent as FOSUN grants to Ardelyx pursuant to this Agreement under FOSUN Sole Invention Patents, Sole Program Know-How owned by FOSUN, FOSUN’s interest in the Joint Technology and FOSUN [***] Technology, including without limitation the licenses and rights granted to Ardelyx pursuant to Section 2.05 and Article XI. FOSUN shall remain liable for any action or failure to act by any Sublicensee, or any other Party that is granted a sublicense under the licenses granted in Section 2.01 by FOSUN, its Affiliates or its Sublicensees, if such action or failure to act by the Sublicensee would have constituted a breach of this Agreement if such action or failure were committed by FOSUN.

For clarity, Ardelyx currently expects to enter into additional license agreements for the further development and commercialization of tenapanor outside of the Territory, and the provisions of this Agreement relating to certain Intellectual Property Controlled by FOSUN, its Sublicensees or Affiliates, or by Ardelyx, its licensees or Affiliates are intended to [***] to Intellectual Property that [***] with respect to Intellectual Property that [***].

Section 2.03 Distributorships. FOSUN shall have the right, in its sole discretion, to appoint its Affiliates, and FOSUN, its Affiliates and its Sublicensees shall have the right, in their sole discretion, to appoint any other Persons in the Territory to distribute, market and sell the Licensed Products in the Territory, with or without packaging rights. In circumstances where such appointed Person purchases its requirements of Licensed Products from FOSUN, its Affiliates or its Sublicensees, but does not otherwise make any royalty or other payment to FOSUN, its Affiliates or its Sublicensees with respect to Intellectual Property Rights, and where such Person is not an Affiliate of FOSUN and neither FOSUN nor any of its Affiliates shares in the profits from, or has an equivalent interest in the proceeds from, the sale of Licensed Products by such Person, that Person shall be a “Distributor” for purposes of this Agreement. The term “packaging rights” in this ‎Section 2.03 shall mean the right for the Distributor to package Licensed Products supplied in unpackaged bulk form into individual ready-for-sale packs. FOSUN shall ensure that its legal contracts with its Distributors restrict such Distributor from selling or exporting the Licensed Product out of the Territory. FOSUN shall remain liable for any action or failure to act by the Distributor, if such action or failure to act by the Distributor would have constituted a breach of this Agreement if such action or failure were committed by FOSUN.

This Agreement confers no right, license, or interest by implication, estoppel, or otherwise under any Patents, Know-How, or other Intellectual Property Rights of either Party except as expressly set forth in this Agreement. Each Party hereby expressly retains and reserves all rights and interests with respect to Patents, Know-How, or other Intellectual Property Rights not expressly granted to the other Party hereunder.

Section 2.08 Exclusivity Term. FOSUN’s exclusive licenses granted under Section 2.01, shall expire with respect to each separate Licensed Product on the date when FOSUN’s obligation to pay royalties with respect to such Licensed Product expires pursuant to ‎Section 6.04(e).

At Ardelyx’s election, in addition to its obligation set forth in Section 11.03(h) to seek to assign to Ardelyx Third Party agreements with respect to the Manufacture of Licensed Product, FOSUN shall transfer to Ardelyx any inventory of Licensed Compound and/or Licensed Product that FOSUN has in its Control as of the effective date of such foregoing termination (except for such quantities as FOSUN may need to retain for reference purposes), and Ardelyx shall in consideration thereof pay to FOSUN the Cost of Goods for such inventory. At all times, FOSUN shall provide reasonable assistance to Ardelyx with respect to the transfer of Information and Materials so as to permit Ardelyx to begin Manufacturing and supplying its requirements of Licensed Product as soon as possible to minimize any disruption in the continuity of supply. FOSUN covenants to Ardelyx that any Third Party agreements under which FOSUN engages such Third Party to manufacture Licensed Products shall contain provisions regarding the allocation of Intellectual Property Rights and rights in work product that are consistent with the terms of this Agreement and will enable FOSUN to fulfill its obligations to Ardelyx under this Section.

Section 5.05 Other Supply. Notwithstanding anything to the contrary herein, FOSUN shall not supply Licensed Compound or Licensed Products to any Third Party for any Third Party use, other than to Develop and Commercialize Licensed Products in compliance with this Agreement. In addition, FOSUN shall not license any Third Party (other than a Sublicensee or other sublicensee consistent with the terms and conditions of this Agreement) to make or have made Licensed Products, except to carry out the provisions of this Article V. FOSUN shall not Manufacture or have Manufactured Licensed Compound, nor shall FOSUN authorize or license any Third Party to Manufacture or to have Manufactured Licensed Compound. FOSUN shall not purchase any Licensed Compound from any party other than Ardelyx, and FOSUN shall not purchase any Licensed Product from any party other than Ardelyx or a Third Party under written agreement with FOSUN to Manufacture Licensed Product for sale to FOSUN, its Affiliates and/or its Sublicensees.

[***]	]Fifteen Million] ([***]) USD
[***]	[*] ([*]) USD
[***]	[*] ([*]) USD

(b) Sales between FOSUN, its Affiliates and Sublicensees shall not be subject to sales milestones hereunder. Sales milestones shall be calculated on FOSUN’s, its Affiliates’ and Sublicensees’ sales of the Licensed Products to a Third Party, including Distributors (but excluding for the avoidance of doubt Sublicensees).

(c) In the event that more than one of the sales milestones set forth in Section 6.03(a) are achieved in the same Calendar Year, the payment associated with each sales milestone achieved in such Calendar Year shall be due and payable by FOSUN to Ardelyx following the end of such Calendar Year.

(d) No payments pursuant to Section 6.03(a) shall be creditable against any other payments FOSUN is obligated to make to Ardelyx under this Agreement.

Section 6.04 Royalties.

(a) Subject to the provisions set forth below in Section 6.04(c) through Section 6.04(f), and Section 6.05, FOSUN shall pay to Ardelyx a royalty on aggregate Annual Net Sales of the Licensed Products made by FOSUN, its Affiliates, or its Sublicensees at the following rate:

Confidential Portions of this Exhibit marked as [***] have been omitted

Range of Annual Net Sales	Royalty Rate
[***]	[***]%
[***]	[***]%
[***]	[***]%
[***]	[***]%

Each Royalty Rate set forth in the table above shall apply only to that portion of the Net Sales in the Territory during a given Calendar Year that falls within the indicated range. For illustration purposes only, if Annual Net Sales in the Territory during a Calendar Year is $[***], then the aggregate royalties payable with respect thereto will be $[***], with calculation as follows: (i) $[***] multiplied by [***]% = $[***], plus (ii) $[***] multiplied by [***]% = $[***], plus (iii) $[***] multiplied by [***]% = $[***], and plus(iv) $[***] multiplied by [***]% = $[***].

(b) Sales between FOSUN, its Affiliates and Sublicensees shall not be subject to royalties hereunder. Royalties shall be calculated on FOSUN’s, its Affiliates’ and Sublicensees’ sales of the Licensed Products to a Third Party, including Distributors (but excluding for the avoidance of doubt Sublicensees).

(c) If, at any time, (i) a Generic Product receives Regulatory Approval in the Territory and (ii) the aggregate number of units of the relevant Licensed Product sold in the Territory in a given Calendar Year (after the first Calendar Year in which the Generic Product is sold in the Territory) decrease by more than [***] percent ([***]%) compared to the Calendar Year immediately preceding the first Calendar Year in which the Generic Product is sold, then, the royalties that would otherwise have been payable on Net Sales of such Licensed Product in the Territory under this Agreement shall be reduced by [***] percent ([***]%) as from the first Calendar Year in which this Section 6.04(c) applies and thereafter for so long as the aggregate number of units of the relevant Licensed Product sold in a given Calendar Year are at least [***] percent ([***]%) less than the number of units of such Licensed Product sold in the Calendar Year immediately preceding the first Calendar Year in which the Generic Product is sold. The calculation of the royalty reduction under this Section 6.04(c) shall be conducted separately for each Licensed Product.

(d) Any reductions set forth in Section 6.04(c) and Section 6.04(f) shall be applied in the order in which the event triggering such reduction occurs, provided that in no event shall, due to the cumulative reductions set out in Section 6.04(c), and Section 6.04(f), the royalties that would otherwise have been payable to Ardelyx under this Section 6.04 in a particular Calendar Quarter

Confidential Portions of this Exhibit marked as [***] have been omitted

be reduced by more than [***] percent ([***]%) of that which would be due pursuant to Section 6.04(a). [***]

(e) FOSUN’s obligation to pay royalties due under this Section 6.04 shall commence with respect to each separate Licensed Product, on the date of the First Commercial Sale of such Licensed Product and shall expire with respect to such Licensed Product, at the latest of: (i) the [***] anniversary of the First Commercial Sale of such Licensed Product in the Territory, (ii) the date on which there is no longer a Valid Claim that covers the Exploitation of the Licensed Product or the Licensed Compound in the Territory, and (iii) the expiration of all Regulatory Approvals for such Licensed Product in the Territory. At such time as FOSUN’s obligation to pay royalties under this Section 6.04 have expired with respect to a Licensed Product, the license granted to FOSUN under Section 2.01 shall automatically, and without further action on the part of Ardelyx or FOSUN, become non-exclusive, fully-paid, irrevocable and perpetual with respect to such Licensed Product and the Net Sales of such Licensed Product shall be excluded from royalty calculations under this Section 6.04 (including for purposes of applying thresholds and ceilings). Notwithstanding the foregoing, FOSUN’s exclusivity to such Licensed Product shall continue if FOSUN elects to keep paying the royalties as defined in this Section 6.04 after the expiration of its obligation to pay royalties due.

(f) If (i) [***] that it is necessary to obtain a license from any Third Party in order to avoid infringement of such Third Party’s Patent in the Territory, (ii) such Patent claims the [***], (iii) there are not any other [***] alternatives available to avoid such infringement, and (iv) FOSUN is required to pay to such Third Party a royalty, milestone payments or other monetary compensation in consideration for the grant of such license (“Third Party Compensation”), then, provided that Ardelyx has consented in writing to the terms (including, without limitation, the payment terms) of the Third Party license under which the Third Party Compensation is payable prior to the execution of such Third Party license, for the period during which FOSUN owes royalties to Ardelyx hereunder, the amounts that would otherwise have been payable as royalties to Ardelyx under this Agreement shall be reduced by the amount of all Third Party Compensation payable by or on behalf of FOSUN to such Third Party. [***]. For the avoidance of doubt, provided that Ardelyx has consented in writing to the terms (including, without limitation, the payment terms) of the Third Party license under which the Third Party Compensation is payable prior to the execution of such Third Party license, Ardelyx shall [***].

Section 6.05 Combination Products. In the event Ardelyx is entitled to receive royalties under this Agreement from any Licensed Product sold in the form of a Combination Product in the Territory, then Net Sales for such Combination Product will be calculated by multiplying the actual Net Sales of such Combination Product in the Territory by the fraction A/(A+B), where A is the standard sales price in the Territory of a Licensed Product, containing the same amount of Licensed Compound as the sole active ingredient as the Combination Product in question (a “Comparable Licensed Product”), if sold separately, and B is the standard sales price in the Territory of the ready for sale form of a product containing the same amount of the other therapeutically active ingredient(s) in the Combination Product that are not Licensed Compounds (the “Other Ingredients”), if sold separately. If the Other Ingredients are not sold separately in the Territory, Net Sales for the purpose of determining royalties of the Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction A/C where A is the standard sales price in the Territory of a Comparable Licensed Product,

Confidential Portions of this Exhibit marked as [***] have been omitted

if sold separately, and C is the standard sales price of the Combination Product in the Territory. If a Comparable Licensed Product is not sold separately, Net Sales for the purpose of determining royalties of the Combination Product shall be calculated by multiplying actual Net Sales of such Combination Product by the fraction (C-B)/C, where B is the standard sales price in the Territory of the Other Ingredients and C is the standard sales price in the Territory of the Combination Product. For the purpose of the above, the standard sales price for a Comparable Licensed Product and for each Other Ingredient shall be for a quantity comparable to that used in the Combination Product in question and of the same class, purity and potency. If neither a Comparable Licensed Product nor the Other Ingredients are sold separately in the Territory, Net Sales for the purposes of determining royalties of such Combination Product shall be determined by the Parties on the basis of a fair market value of such Comparable Licensed Product and Other Ingredient to be negotiated by the Parties in good faith, taking into account costs, overheads and profit of the relevant Licensed Compound(s), the Other Ingredients and the Combination Product. For purposes of the calculations set forth in this Section 6.05, prior to the First Commercial Sale of a Combination Product, the SC shall discuss the calculations set forth herein, including the standard sale prices to be used in such calculation.

Section 6.06 Sales by Sublicensees. In the event FOSUN grants sublicenses to one or more Sublicensees to make or sell Licensed Products to the extent permitted hereunder, such sublicenses shall include without limitation an obligation for the Sublicensee to account for and report its Net Sales of such Licensed Products on the same basis as if such sales were Net Sales by FOSUN, and FOSUN shall pay royalties and sales milestones to Ardelyx as if the Net Sales of the Sublicensee were Net Sales of FOSUN.

Section 6.07 Royalty Payments and Reports. The royalties payable under Section 6.04 shall be calculated quarterly as of the last day of March, June, September and December respectively for the Calendar Quarter ending on that date. FOSUN shall deliver to Ardelyx a report summarizing the Net Sales of Licensed Products during each Calendar Quarter following the First Commercial Sale of a Licensed Product in the Territory. A draft of such report shall be provided within [***] days the end of each Calendar Quarter for which royalties are due from FOSUN to allow Ardelyx to estimate its royalty payments from FOSUN. A final report shall be delivered within [***] ([***]) Business Days following the end of each Calendar Quarter . Any royalties payable to Ardelyx or its designee under this Agreement shall be paid on the date that final report for the Calendar Quarter is delivered to Ardelyx under this Section 6.07.

Section 6.08 Taxes.

(a) The royalties, milestones and other amounts payable by FOSUN to Ardelyx pursuant to this Agreement (“Payments”) shall not be reduced on account of Taxes unless required by Applicable Laws. To the extent any payments made by FOSUN pursuant to this Agreement become subject to withholding Taxes under Applicable Laws, FOSUN shall deduct and withhold the amount of such Taxes for the account of Ardelyx to the extent required by Applicable Laws; such amounts payable to Ardelyx shall be reduced by the amount of withholding Taxes deducted and withheld; and FOSUN shall pay the amounts of such Taxes to the proper governmental authority in a timely manner and transmit to Ardelyx an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant governmental authority of all amounts deducted and withheld sufficient to enable Ardelyx to claim such payment of Taxes.

Confidential Portions of this Exhibit marked as [***] have been omitted

Any such withholding Taxes required under Applicable Laws to be paid or withheld shall be an expense of, and borne solely by, Ardelyx. Except as provided in this Section 6.08(a), all taxes or duties in connection with payments made by FOSUN for Indirect Taxes, including any value added or similar tax or local tax or surcharge on value added taxes and any import duty or fees, shall be borne by FOSUN.. Notwithstanding the foregoing, if Ardelyx is entitled (whether under any applicable tax treaty or otherwise under Applicable Laws) to a reduction in the rate of, or the elimination of, withholding Tax, it may deliver to FOSUN or the appropriate governmental authority (with the assistance of FOSUN to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve FOSUN of its obligation to withhold Tax, and FOSUN shall apply the reduced rate of withholding, or dispense with withholding, as the case may be. FOSUN agrees to take reasonable and lawful efforts to minimize such Taxes to Ardelyx. FOSUN shall cooperate with Ardelyx as reasonably requested in any claim for refund or application to any Tax Authority. If FOSUN intends to withhold Tax from any Payment, FOSUN shall inform Ardelyx reasonably in advance of making such Payment to permit Ardelyx an opportunity to provide any forms or information or obtain any Tax Authority approval as may be available to reduce or eliminate such withholding.

(b) Tax Gross-up. Notwithstanding anything to the contrary herein, if (i) FOSUN redomiciles or assigns its rights or obligations under this Agreement, (ii) as a result of such redomiciliation or assignment, FOSUN (or its assignee) is required by Applicable Law to withhold taxes, or such redomiciliation or assignment results in the imposition of Indirect Taxes that were not otherwise applicable, from or in respect of any amount payable under this Agreement, and (iii) such withholding taxes or Indirect Taxes exceed the amount of withholding taxes or Indirect Taxes that would have been applicable but for such redomiciliation or assignment, then any such amount payable to Ardelyx pursuant to this Agreement shall be increased to take into account such withholding taxes or Indirect Taxes as may be necessary so that, after making all required withholdings (including withholdings on the additional amounts payable) and/or paying such Indirect Taxes, as the case may be, Ardelyx receives an amount equal to the sum it would have received had no such increased withholding been made and no such Indirect Taxes had been imposed. The obligation to pay additional amounts pursuant to the preceding sentence shall not apply, however, to the extent such increased withholding tax or Indirect Taxes would not have been imposed but for the assignment by Ardelyx of its rights or obligations under this Agreement or the redomiciliation of Ardelyx outside of the United States, to the extent such assignment or redomiciliation occurs after the redomiciliation or assignment by FOSUN described in the first sentence of this Section 6.08(b). Solely for purposes of this Section 6.08(b), a Party’s “domicile” shall include its jurisdiction of incorporation or tax residence and a “redomiciliation” shall include a reincorporation or other action resulting in a change in tax residence of the applicable Party or its assignee.

(c) Notwithstanding anything to the contrary contained in this ‎Section 6.08 or elsewhere in this Agreement, the following shall apply with respect to Indirect Taxes. If any Indirect Taxes are chargeable in respect of any Payments, FOSUN shall be responsible for such Indirect Taxes and shall not reduce any Payments due Ardelyx hereunder as a result of such Indirect Taxes. FOSUN shall pay such Indirect Taxes at the applicable rate in respect of any such Payments following the receipt, where applicable, of an Indirect Taxes invoice issued by Ardelyx in respect of those Payments, such Indirect Taxes to be payable on the due date of the payment of

the Payments to which such Indirect Taxes relate or at the time such Indirect Taxes are required to be collected by Ardelyx, in the case of payment of Indirect Taxes to Ardelyx. The sum of the net amount received by Ardelyx and the withholding income Tax levied by China Tax Authority discussed in Section 6.08(a) above for each payment shall not be less than the amount of the Upfront and Milestone Payments set forth in Section 6.01, 6.02 and 6.03.The Parties shall issue invoices for all goods and services supplied under this Agreement consistent with Indirect Tax requirements, and to the extent any invoice is not initially issued in an appropriate form, FOSUN shall promptly inform Ardelyx and shall cooperate with Ardelyx to provide such information or assistance as may be necessary to enable the issuance of such invoice consistent with Indirect Tax requirements.

Section 6.09 Payments or Reports by Affiliates. Any Payment required under any provision of this Agreement to be made to Ardelyx or any report required to be made by FOSUN shall be made by an Affiliate of FOSUN if such Affiliate is designated by FOSUN as the appropriate payer or reporting entity.

Section 6.10 Mode of Payment. All payments set forth in this ‎Article VI shall be remitted by wire transfer to the bank account of Ardelyx as designated in writing to FOSUN.

Section 6.11 Payment Currency. All amounts payable and calculations under this Agreement shall be in United States dollars. As applicable, Net Sales and any adjustments to payments under this Agreement shall be translated into United States dollars at an exchange rate determined by using the 30-day trailing average of the daily Middle Exchange Rate for the renminbi of People’s Bank of China (the central bank of the government of China) as published daily at xxxx://xxx.xxxx.xxx.xx/xxx/xxxxxx/xxxxxxx/Xxxx.

Section 6.12 Imports. For the avoidance of doubt, the Parties acknowledge and agree that none of the milestones or royalties payable under this Agreement are related to the license (or right) to import or any import of Licensed Products. FOSUN shall be responsible for any import clearance, including payment of any import duties and similar charges, in connection with any Licensed Products or Licensed Compounds transferred to FOSUN under this Agreement. The Parties shall co-operate in accordance with Applicable Laws to ensure where permissible that no import duties are paid on imported materials. Where import duties are payable, the Parties shall co-operate to ensure that the Party responsible for shipping values the materials in accordance with Applicable Laws and minimizes where permissible any such duties and any related import taxes that are not reclaimable from the relevant authorities.

Section 6.13 Discounted Sales. In the event that one or more Licensed Products is included as part of a package of products offered to customers of FOSUN, and discounts on packages including Licensed Products are offered independently in the Territory, FOSUN shall not discount the price of the Licensed Products sold as part of a package unreasonably compared to the discount FOSUN offers on prices of the other products included in such package.

Section 8.02 Ownership.

(a) Inventorship of all inventions and other Know-How conceived or first made in the course of activities performed after the Effective Date in the course of the Parties’ performance under this Agreement shall be determined in accordance with the laws of inventorship of the United States. Subject to the licenses granted in Article II and to the other provisions of this Agreement, all such inventions and other Know-How invented by employees or independent contractors of one Party (“Sole Program Know-How”) shall be solely owned by the inventing Party, and any inventions and Know-How that are invented jointly by employees or independent contractors of each Party will be owned jointly by the Parties (“Joint Know-How”). For clarity, Ardelyx’s Development and Commercialization of a Licensed Compound or Licensed Product outside of the Field and/or outside of the Territory shall not be activities performed in the course of Ardelyx’s performance under this Agreement, and any inventions and other Know-How conceived or first made during the course of such Development and Commercialization shall be Ardelyx [***] Technology rather than Sole Program Know-How owned by Ardelyx.

(b) To the extent permissible under Applicable Laws, each Party will ensure that prior to conducting work on such Party’s behalf under this Agreement, each employee and contractor is obligated by Applicable Law, or written contract to (i) promptly disclosure to such Party of all inventions and Know-How conceived or reduced to practice by such employee or contractor during any performance under this Agreement, (ii) automatically assign to such Party all right, title and interest in and to all such inventions and Know-How and all Intellectual Property Rights therein, and (iii) adhere to similar obligations of confidentiality as are set forth in this Agreement. Each

Confidential Portions of this Exhibit marked as [***] have been omitted

Party will require each employee and contractor conducting work on such Party’s behalf under this Agreement to maintain records in sufficient detail and in a good scientific manner appropriate for regulatory purposes and purposes of pursuing Patent protection on inventions to properly reflect all work done.

Section 8.03 Prosecution and Maintenance of Patent Rights.

(a) Ardelyx. Ardelyx (or with respect to Ardelyx [***] Patents, Ardelyx or its licensor) shall be primarily responsible for and control the worldwide preparation, filing, prosecution (including without limitation conducting any interferences, oppositions, reissue proceedings, reexaminations and patent term extensions) and maintenance of Licensed Patents, Ardelyx [***] Patents and Joint Patents (collectively, the “Ardelyx Controlled Patents”); provided that with respect to all Ardelyx Controlled Patents, other than Ardelyx [***], Ardelyx shall provide FOSUN with advance copies of, and a reasonable opportunity to comment upon, proposed patent filings, related prosecution strategies and proposed correspondence with patent officials, all to the extent in the Territory and relating to any Ardelyx Controlled Patents (other than the Ardelyx [***]), and will consider comments received from FOSUN with respect to such proposed filings, strategies and correspondence in the Territory in good faith and will not unreasonably reject such comments. Ardelyx agrees to discuss in good faith any changes reasonably requested by FOSUN to such filings, strategies and correspondence in the Territory upon their being received.

(b) FOSUN. FOSUN shall be primarily responsible for and control the worldwide preparation, filing, prosecution (including without limitation conducting any interferences, oppositions, reissue proceedings, reexaminations and patent term extensions) and maintenance of FOSUN Sole Invention Patents, FOSUN [***] Patents (“FOSUN Controlled Patents”) using in-house patent attorneys or counsel reasonably acceptable to Ardelyx; provided with respect to all FOSUN Controlled Patents, other than FOSUN [***], that FOSUN shall provide Ardelyx with advance copies of, and a reasonable opportunity to comment upon, proposed patent filings, related prosecution strategies and proposed correspondence with patent officials or other Third Parties relating to any FOSUN Sole Invention Patents, and will consider comments received from Ardelyx with respect to such proposed filings, strategies and correspondence in good faith and will not unreasonably reject such comments. FOSUN agrees to discuss in good faith any changes reasonably requested by Ardelyx to such filings, strategies and correspondence promptly upon their being received. FOSUN agrees to implement any such recommended changes with the goal of optimizing overall patent protection for Licensed Compounds and Licensed Products, and Joint Technology. In any event, FOSUN will not finally abandon any claims and will not limit any claims that are specific to Licensed Compounds or Licensed Products without Ardelyx’s prior written consent.

(c) The Party responsible for prosecuting Patents pursuant to Section 8.03(a) or Section 8.03(b) shall provide all documentation it is required to provide pursuant to such Sections so as to provide the other Party a reasonable opportunity to review and comment thereon in advance of filing. A Party providing comments in accordance with Section 8.03(a) or Section 8.03(b) shall provide such comments expeditiously and in any event in reasonably sufficient time to meet any filing deadline communicated to it by the other Party that is consistent with the preceding sentence. The Party receiving any such patent application and correspondence shall maintain such

Confidential Portions of this Exhibit marked as [***] have been omitted

Notwithstanding the above, if (i) such material breach cannot reasonably be cured within such [***] ([***]) day period, (ii) the Breaching Party provides, within such [***] ([***]) day period, the Non-Breaching Party with a written detailed plan that contains measures that can be reasonably expected to cure such breach in a time frame reasonably acceptable to both Parties, which shall not extend beyond [***] ([***]) months from the date the plan is presented to the Non-Breaching Party, and (iii) the Breaching Party commences to perform such measures in accordance with such plan, and (iv) the Breaching Party thereafter diligently continues to perform such measures as detailed in such plan, then the Non-Breaching Party shall not be entitled to terminate this Agreement (and any notice of termination issued pursuant to the foregoing sentence shall not become effective) unless and until the earlier of (x) the Breaching Party ceases to diligently perform such measures despite then not having cured the breach, or (y) the Breaching Party fails to cure the breach in the time frame agreed to by the Non-Breaching Party in the plan, which shall not exceed [***] ([***]) months from the date the plan is presented to the Non-Breaching Party.

(b) Ardelyx hereby agrees to indemnify, defend and hold harmless FOSUN, its Affiliates, and each of its and their respective employees, officers, directors and agents from an against any and all Losses incurred by them resulting from or arising out of or in connection with any Third Party Claims against FOSUN, its Affiliates or their respective employees, officers, directors or agents, that result from or arise out of [***]; except in any case, to the extent such Losses are Losses for which FOSUN has an obligation to indemnify Ardelyx, its Affiliates or their respective employees, officers, directors or agents pursuant to Section 12.01(a), as to which Losses each Party shall indemnify the other to the extent of their respective liability for such Losses.

Each such notice shall contain a description of the Third Party Claim and the nature and amount of the Loss claimed (to the extent that the nature and amount of such Loss is known at

Confidential Portions of this Exhibit marked as [***] have been omitted

such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any such Third Party Claim or Losses.

The Indemnified Party shall permit the Indemnifying Party to assume direction and control of the defense of the relevant Third Party Claim (including without limitation the right to settle the claim solely for monetary consideration), and shall cooperate as requested (at the expense of the Indemnifying Party) in the defense of the claim. The assumption of the defense of a Third Party Claim by the Indemnifying Party shall not be construed as an acknowledgement that the Indemnifying Party is liable to indemnify any Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against any Indemnified Party’s claim for indemnification.

Notwithstanding the provisions of Section 12.02(a) requiring the Indemnified Party to tender to the Indemnifying Party the exclusive ability to defend such claim, if the Indemnifying Party declines to or fails to timely assume control of the relevant Third Party Claim, the Indemnified Party shall be entitled to assume such control, conduct the defense of, and settle such claim, all at the sole costs and expense of the declining or failing Party; provided, however, that neither Party shall settle or dispose of any such claim in any manner that would adversely affect the rights or interests or admit fault, of the other Party without the prior written consent of such other Party, which shall not be unreasonably withheld, delayed or conditioned. Each Party, at the other Party’s expense and reasonable request, shall cooperate with such other Party and its counsel in the course of the defense or settlement of any such claim, such cooperation to include without limitation using reasonable efforts to provide or make available documents, information, and witnesses.

Section 12.03 Insurance. Each Party shall have and maintain such type and amounts of liability insurance covering the Manufacture, supply, use and sale of the Licensed Compounds and the Licensed Products as is normal and customary in the pharmaceutical industry generally for Persons similarly situated, and shall upon request provide the other Party with a copy of its policies of insurance in that regard, along with any amendments and revisions thereto.
