3. DEVELOPMENT, REGULATORY, AND COMMERCIALIZATION

3.1. Development.

3.1.1. Joint Development Committee.

(a) Overview. The Parties will establish a joint development committee (“JDC”) that will be responsible for overseeing the Development of Products in the Field in the Territory, and will serve as a forum for exchanging data, information, and Development strategy regarding the Product. The Parties anticipate that the JDC will perform the functions ascribed to it in this Section 3.1.1; provided, however, that the functions and operations of the JDC may be altered from time to time during the Term by the mutual agreement of the Parties to appropriately address ongoing requirements with respect to the Development and Commercialization of the Product. In addition to the committee meetings, the Parties anticipate that members of Senior Management from Ironwood and Partner will meet periodically as necessary or appropriate during the Term (and in any event at least once per Year) in order to review significant issues and developments in the Development and Commercialization of the Licensed Compound or Product.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

(b) Membership. The JDC will consist of three senior representatives from each Party. Ironwood and Partner will each designate a co-chair for the JDC. The co-chairs will be responsible for calling meetings and setting the agenda (which will include a list of all participants expected at a meeting) and circulating such agenda at least ten days prior to each meeting and distributing minutes of the meetings within 30 days following such meeting (which minutes will be in the English language), but will not otherwise have any greater power or authority than any other member of the JDC. JDC members must have such expertise as appropriate to the activities of the JDC, and from time to time the JDC may invite personnel of the Parties having formulation, manufacturing, commercial, marketing, and other expertise to participate in discussions of the JDC as appropriate to assist in the activities of the JDC.

(c) Responsibilities. The JDC’s responsibilities will include, among others: (i) preparing and approving the Development Plan and any amendments to such plan, (ii) approving (or establishing procedures to approve) protocols for pre-clinical or clinical studies (including Post- Approval Research), (iii) making modifications to and performing quarterly monitoring of progress of pre-clinical and clinical studies and proposing additional studies for the Product, (iv) reviewing Partner’s budget for Developing the Product, (v) reviewing and commenting on Regulatory Submissions relating to the Product, and (vi) facilitating the exchange of all data, information, material or results relating to the development of the Product. The JDC may appoint additional committees as desired. Notwithstanding the foregoing, Partner acknowledges and agrees that any Development Plan approved by the JDC will be subject to review by the Joint Development Committee constituted under the Forest Agreement, and that no clinical Development of the Product may be conducted in the Forest Territory which Forest reasonably believes may adversely affect the timely Development of any Product in the Forest Territory.

(d) Meetings. During Development, the JDC will meet at such frequency as will be established by the Parties (but not less frequently than four times per Year prior to receipt of the first Regulatory Approval and as mutually agreed thereafter). Meetings of the JDC will alternate between the offices of the Parties, unless otherwise agreed upon by the members of the JDC, or may be held telephonically or by video conference. Meetings of the JDC will be effective only if at least one representative of each Party is in attendance or participating in the meeting. Members of the JDC may participate in and vote at meetings by telephone. Each Party will be responsible for expenses incurred by its employees and its members of the JDC in attending or otherwise participating in JDC meetings. Each Party will use reasonable efforts to cause its representatives to attend the

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

meetings of the JDC. If a representative of a Party is unable to attend a meeting, such Party may designate an alternate with equivalent experience and authority as such representative to attend such meeting in place of the absent representative.

(e) Minutes. The minutes of each JDC meeting must provide a description in reasonable detail of the discussions held at the meeting and a list of any actions, decisions or determinations approved by the JDC. Minutes of each JDC meeting will be approved or disapproved, and revised as necessary, at the next meeting.

(f) Elevation and Dispute Resolution. Each Party’s representatives on the JDC will collectively have one vote on all matters that are within the responsibility of such committee. The members of each committee will use reasonable efforts to reach consensus on all decisions. In the event that the members of the JDC are unable to agree on a particular issue, such issue will be referred to the Parties’ respective Chief Scientific Officers or equivalent or their designees. In the event such individuals are unable to resolve such issue within 15 days, such issue will be referred to the Chief Executive Officers of each Party or their designees for resolution. Subject to the remaining provisions of this Section 3.1.1(f), all matters relating to Development, including, without limitation, amendments and modifications to the Development Plan, must be determined by consensus of the Parties. The Parties will from time to time identify a panel of mutually agreed consultants with expertise in pharmaceutical development to assist the JDC in the resolution of development issues and, upon the request of either Party, such experts will be requested to advise as to Development issues where consensus cannot be reached, with the advice of such experts not to be unreasonably rejected. Notwithstanding the foregoing, if a matter for which consensus cannot be reached is addressed by the then current Development Plan, then such Development Plan and the activities required thereunder will control despite any inability of the Parties to reach consensus.

3.1.2. Product Development Plan. The initial Development Plan for the Product in the Field is set forth in Exhibit C (the “Initial Development Plan”). The JDC will direct, coordinate, and manage the Development of the Product in the Field, according to the Development Plan. The Development Plan for the Product will include, among other things, the indications in the Field for which the Product is to be Developed and other exploratory indications in the Field for which the Product may be developed, critical activities to be undertaken, certain timelines, go/no go decision points and relevant decision criteria and certain allocations of responsibilities between the Parties for the various activities to be undertaken under the Development Plan. During the Term, the JDC will amend the Development Plan on an ongoing basis as necessary.

3.1.6. Non-Development Plan Activities. All Development work proposed to be undertaken and not provided for in the then current Development Plan will be submitted for consideration by the JDC. In the event the JDC determines not to include such proposed Development activities in the Development Plan, which determination will be made within 120 days of its receipt of such proposal, and neither Party has any reasonable objection from a Development, Commercialization or regulatory point of view to the conduct of such Development activities, the Party proposing such Development activities has the right to conduct such activities [**].

3.1.7. Reports of Development Activities. Partner will report on Development activities undertaken by it in accordance with Development Plan in connection with meetings of the JDC, including by providing a reasonably detailed summary of all results, data, and material inventions, if any, obtained from such activities. In addition, Partner will, at its own expense, make appropriate scientific and regulatory personnel available to Ironwood, either by telephone or in person as the Parties may mutually agree, as reasonably required to keep Ironwood informed of Development activities.

3.1.8. Third Party Comparative Information. In the event either Party from time to time possesses objective Third Party information (for example, from a qualified contract research organization) which indicates that specific Development activities can be achieved in a more cost-effective manner than as provided by the Development Plan or as such plan is then being implemented, the JDC will review and give due regard to such information with the obligation of achieving such cost savings to the extent attainable without negatively impacting conduct of the Development Plan, including, without limitation, the timing and quality of Development activities.

Partner will not submit any Regulatory Submissions unless the Parties have complied with the preceding two sentences with respect to such Regulatory Submissions. Ironwood will make available to Partner with respect to the Licensed Compound or Products any Regulatory Submissions made pursuant to the Forest Agreement. Partner will own all right, title, and interest in all Regulatory Submissions and Regulatory Approvals for Products in the Territory.

3.2.2. Regulatory Cooperation. Partner will keep Ironwood reasonably informed regarding the status and progress of Development activity, including without limitation, providing Ironwood with advance notice of all meetings scheduled with a Regulatory Authority (including notice within 24 hours of a request for a meeting received from a Regulatory Authority) related to the Licensed Compound, and an agenda and an invitation to attend such meetings, providing Ironwood with a copy of all substantive written correspondence from a Regulatory Authority involving a Regulatory Submission, notifying Ironwood of all oral substantive correspondence from a Regulatory Authority involving a Regulatory Submission, and providing Ironwood with an advance draft of each proposed Regulatory Submission sufficiently in advance of providing the submission to the Regulatory Authority (and in any event no less than 15 days in advance) to enable Ironwood to comply with the provisions of Section 3.2.1 and to have a meaningful opportunity to provide comments on the content of such submission and no such submission (including any NDA) may be submitted for filing with the Regulatory Authority without the mutual agreement of the Parties, such consent of Ironwood not to be unreasonably withheld or delayed. Furthermore, the Parties will agree in advance on all substantive written communications with and, to the extent permitted by Applicable Law, will both have the right to participate in all meetings and oral communications with Regulatory Authorities in the applicable countries in the Territory to the extent related to the Product. Partner will also provide to Ironwood copies of all Regulatory Submissions in the form actually submitted to Regulatory Authorities.

(a) the Transfer Price paid by Partner for Commercial supply of Licensed Compound pursuant to Section 3.3 to the extent such Transfer Price relates to the purchase by Partner of Licensed Compound included in the Product actually sold (excluding samples and other transfer of Products without consideration) in such Calendar Quarter and such Licensed Compound was purchased by Partner from Ironwood no more than 36 months prior to the date of the sale of such Product;

(b) the excess of (i) the Transfer Price paid by Partner for Licensed Compound that was included in Products actually provided as samples by Partner to Third Parties without charge in such Calendar Quarter, and which Partner fully documents in the relevant Quarterly Report pursuant to Section 4.4, over (ii) Ironwood’s Fully Absorbed Cost for such Licensed Compound; and

In case that the deductible amounts, in any Calendar Quarter calculation, are higher than the royalty that would otherwise be owed for such Calendar Quarter, no payment will be due from Partner to Ironwood, and the difference will be credited to Partner to be deducted from future royalty payments owed to Ironwood.

In no event will Ironwood be required to refund to Partner any Transfer Price paid by Partner pursuant to Section 3.3.

4.3.5. Calculation of Royalties at End of Year. At the end of each Year, promptly after the royalty calculation of the royalty owed pursuant to Section 4.3.2 for the fourth Calendar Quarter of the preceding Year, the royalties owed to Ironwood for such Year (the “Annual Royalties”) will be equal to (i) [**]

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

less (ii) [**]. The amount of royalties paid with the Quarterly Report provided pursuant to Section 4.4 relating to the fourth Calendar Quarter of each Year will be equal to the Annual Royalties for such Year less the royalties paid for the first three Calendar Quarters of such Year.

However, Partner will in no event be obliged to pay to Ironwood any royalties under Sections 4.3.1 and/or 4.3.2 in any Year in which [**] that would otherwise be owed to Ironwood in such Year; provided that, in no event will Ironwood be obligated to [**] paid pursuant to this Agreement.

4.4. Quarterly Reports. Within 45 days after the beginning of each Calendar Quarter beginning with the Calendar Quarter in which the First Commercial Sale following receipt of Regulatory Approval, Partner will deliver to Ironwood a report setting forth for the previous Calendar Quarter the following information on a Product-by-Product and country-by-country basis: (a) the gross sales and Net Sales of each Product in the Territory, (b) the number of units sold by Partner, its Affiliates or Sublicensees and provided as samples without charge to any Third Party, (c) the basis for any adjustments to the royalty payable for the sale of each Product, (d) the royalty due hereunder for the sales of each Product, (e) all Sublicense Income received by Partner and the portion of any Sublicense Income due under Section 4.3.3, and (f) the applicable exchange rate as determined in accordance with this Agreement. The total royalty due for the sale of Products during such Calendar Quarter will be remitted at the time such report is made.

4.5. Records and Audits. During the Term of this Agreement, Partner will keep and maintain accurate and complete records regarding Net Sales and Sublicense Income during the three preceding Years. Upon 15 days prior written notice from Ironwood, Partner will permit an independent certified public accounting firm of internationally recognized standing, selected by Ironwood and reasonably acceptable to Partner, to examine the relevant books and records of Partner and its Affiliates, as may be reasonably necessary to verify the royalty reports submitted by Partner in accordance with Section 4.4. An examination by Ironwood under this Section 4.5 will occur not more than once in any Year and will be limited to the pertinent books and records for any Year ending not more than 36 months before the date of the request. The accounting firm will be provided access to such books and records at Partner’s facility or facilities where such books and records are normally kept and such examination will be conducted during Partner’s normal business hours. Partner may require the accounting firm to sign a standard non-disclosure agreement before providing the accounting firm access to Partner’s facilities or records. Upon completion of the audit, the accounting firm will provide both Ironwood and Partner a written report disclosing whether the reports submitted by Partner are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to Ironwood. If the accountant determines that the royalty report submitted by Partner understated the amount due to Ironwood, then Partner will promptly pay such understated amount, and, if the amount understated by Partner in such royalty reports is more than five percent of the amount that

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

was owed to Ironwood, Partner will reimburse Ironwood for the expense incurred by Ironwood in connection with the audit.

4.6. Taxes and Withholding.

4.6.1. Withholding and Reporting of Tax. Notwithstanding anything else in this Agreement, the Parties agree that all payments under this Agreement will be made free and clear of any withholding tax (including interest, penalties, and additions thereto) (a “Tax”) unless any such deduction or withholding of a Tax is required by any applicable law. If any such deduction or withholding of a Tax is required by any applicable law, then the paying Party will promptly (i) notify the other Party of such requirement; (ii) pay to the relevant authorities the full amount required to be deducted or withheld (including the full amount required to be deducted or withheld from any additional amount paid to Ironwood under Section 4.6.2) promptly upon the earlier of determining that such deduction or withholding is required or receiving notice that such amount has been assessed; and (iii) forward to the other Party an official receipt (or a certified copy), or other documentation reasonably acceptable to the other Party evidencing such payment to such authorities. The paying Party is solely responsible for any Tax that might be required and any related tax information reporting with respect to any payments under the Agreement that may be deemed to arise in the Territory.

4.6.2. Gross-Up for Taxes Paid.

(a) If a deduction or withholding of Tax on a payment to Ironwood under Section 4.1 of this Agreement is required by any applicable law, Partner (including its successors, transferees, and assigns) will pay (or authorize payment) to Ironwood such additional amount as is necessary to ensure that the amount received by Ironwood will equal the payment described in Section 4.1 of this Agreement less [**] of the corresponding deduction or withholding to be applied to said payment. If the U.S. federal income tax liability of Ironwood imposed for any taxable year ending within the Applicable Period (as defined in Section 4.6.4 of this Agreement) for any Tax described in this paragraph is not reduced as a result of a foreign tax credit attributable to such Tax, Partner will pay (or authorize payment) to Ironwood the remaining [**] of such corresponding deduction or withholding as is necessary to ensure that the sum of all payments received by Ironwood pursuant to Section 4.1 and this paragraph will equal [**] Ironwood would have received under Section 4.1 had no such deduction or withholding been required.

(b) If any deduction or withholding of Tax on payments to Ironwood under Sections 4.2 or 4.3 of this Agreement is required by any applicable law, Partner (including its successors, transferees, and assigns) will pay

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

(or authorize payment) to Ironwood such additional amount as is necessary to ensure that the amounts received by Ironwood will equal the amounts described in Sections 4.2 and 4.3 less [**] of the corresponding withholding to be applied to said amounts.

(c) Notwithstanding any other provision in this Section 4.6.2, if the U.S. federal income tax liability of Ironwood is actually reduced as a result of a foreign tax credit claimed by Ironwood with respect to any deduction or withholding by Partner of any Tax under Section 4.6.1., then Partner will not be subject to any further obligation to pay additional amounts under Sections 4.6.2(a) or 4.6.2(b) to the extent that such payment obligation arises on or after the date which is two years after the day on which Ironwood files the income tax return claiming such tax reduction.

4.6.3. Tax Benefit Amount. In the event that Partner (including its successors, transferees, and assigns) makes an additional payment to Ironwood under either Section 4.6.2(a) or 4.6.2(b) and Ironwood notifies Partner of a Tax Benefit Amount (as defined below), Partner may deduct the Tax Benefit Amount once from the royalties owed for a particular Calendar Quarter pursuant to Section 4.3.2. The Tax Benefit Amount will be deducted from the amount of royalties owed to Ironwood in accordance with Section 4.3.4 following the notification to Partner by Ironwood. The Tax Benefit Amount will be available to Partner only to the extent that royalties are owed by Partner to Ironwood after the date of such notification and in no event will Ironwood be required to refund to Partner any Tax Benefit Amount. Partner agrees to pay back any Tax Benefit Amount, in whole or in part, that it deducted from royalties owed to Ironwood promptly upon Ironwood’s request if Ironwood is required to repay such amount to the United States government. “Tax Benefit Amount” means any additional payment to Ironwood under either Section 4.6.2(a) or 4.6.2(b) (or portion thereof) attributable to a Tax that reduces the U.S. federal income tax liability of Ironwood as a result of a foreign tax credit actually claimed by Ironwood. For purposes of the preceding sentence, to the extent any additional payment (or portion thereof) to Ironwood under Section 4.6.2(b) (but, for avoidance of doubt, not Section 4.6.2(a)) has not been classified as a Tax Benefit Amount within the Applicable Period (as defined in Section 4.6.4 below), then such additional payment (or portion thereof) will be deemed to be a Tax Benefit Amount and will be deducted from the amount of royalties owed to Ironwood in accordance with Section 4.3.4 following the close of such Applicable Period.

4.6.4. Applicable Period. With respect to any Tax described in Section 4.6 of this Agreement, the “Applicable Period” will mean the period ending upon the close of the eighth year following the year during which such Tax was paid to the relevant authorities.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

4.6.5. Ironwood Obligation to Claim Timely Foreign Tax Credits. Ironwood will file its U.S. federal income tax returns in a timely manner, and will claim timely reductions of its U.S. federal income tax liability for foreign tax credits attributable to any Tax, with respect to which it has received any additional payment under either Section 4.6.2(a) or 4.6.2(b) to the extent that the claim of any such foreign tax credit (i) is allowed under applicable U.S. income tax laws, and (ii) does not otherwise impose an economic detriment on Ironwood nor on Almirall.

4.7. Equity Investment. Subject to Ironwood obtaining the necessary consents and approvals by its board and shareholders, within 10 days of Successful U.S. Phase III, Partner will purchase from Ironwood capital stock of Ironwood (the “Investment”) for an aggregate purchase price of $15,000,000 as described in this Section. In the event that Successful U.S. Phase III occurs prior to an initial public offering by Ironwood, the Investment will be made pursuant to a Stock Purchase Agreement (as defined below) pursuant to which Partner will purchase 681,819 shares of a new series of preferred stock at a per share purchase price equal to $22.00 per share. In such event, the terms of such purchase will be set forth in a stock purchase agreement in form and substance (including the associated charter amendments and exhibits, the “Stock Purchase Agreement”) as attached hereto as Exhibit E. In the event that Successful U.S. Phase III occurs following an initial public offering by Ironwood, the Investment will be a purchase of 681,819 shares (as appropriately adjusted for any stock dividends, combinations, splits, recapitalizations and the like occurring after the Effective Date) of Series B Common Stock (as such term is defined in the Tenth Amended and Restated Certificate of Incorporation of Ironwood Pharmaceuticals, Inc. attached as an exhibit to the Stock Purchase Agreement), or any security into which all shares of Series B Common Stock have converted or been exchanged prior to such sale, at a per share purchase price equal to $22.00 per share. In such event, the terms of such purchase will be on customary terms for a private investment in a publicly-traded company.

4.8. Currency. With the exception of the royalty rate determination in Section 4.3.2, all amounts payable and calculations hereunder will be in United States dollars. Net Sales will be translated into United States dollars, based on the average closing conversion rate as reported in the Wall Street Journal, for the applicable Calendar Quarter to which such Net Sales. If, due to restrictions or prohibitions imposed by national or international authority, payments cannot be made as provided in this Section 4, the Parties will consult with a view to finding a prompt and acceptable solution, and the paying Party will deal with such monies as the other Party may lawfully direct at no additional out-of-pocket expense to the paying Party.

4.9. Confidentiality. All financial information of a Party which is subject to review under this Section 4 will be deemed to be Confidential Information subject to the provisions of Section 5.1, and such Confidential Information will not be disclosed to any Third Party or used for any purpose other than verifying payments to be made by one Party to the other hereunder; provided, however, that such Confidential Information may

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

be disclosed to Third Parties only to the extent necessary to enforce a Party’s rights under this Agreement.

4.10. Interest. Any payment under this Section 4 that is more than [**] past due will be subject to interest at an annual percentage rate of [**] (as published in the “Money Rates” table of the Eastern Edition of The Wall Street Journal during the period such amount is overdue) [**] if a Party does not make payment within 30 days of its receipt of notice that such amount is past due. Likewise, any overpayment that is not refunded within [**] after the date such overpayment was made will thereafter be subject to interest at an annual percentage rate of [**] (as published in the “Money Rates” table of the Eastern Edition of The Wall Street Journal during period such amount is overdue) [**]; provided, however, that if the overpayment is due to errors in reports provided by the overpaid Party, such interest will accrue from the date the overpayment was made. Notwithstanding the preceding, if a Party contests any amounts due hereunder in good faith and promptly notifies the other Party of such dispute, interest will not accrue as to amounts being so contested until [**] following the presentation of such notice to the other Party.

5. MUTUAL COVENANTS

7.2.1. Ownership of Technology. Determinations as to which Party has invented any Patent Right or Know-How will be made in accordance with the standards of inventorship under U.S. patent law. Subject to the license grants under Section 2 of this Agreement, as between the Parties, Ironwood will own all Ironwood Technology and Partner will own all Partner Technology. Each Party will own an undivided one-half interest in and to the Joint Technology. In the event inventorship and ownership of any Collaboration Technology cannot be resolved by the Parties with advice of their respective intellectual property counsel, such dispute will be resolved through arbitration pursuant to Section 10.1.3, provided such arbitration panel will include at least a single arbitrator who is a specialist in U.S. chemical and pharmaceutical patent law and in chemical and pharmaceutical patents.

7.2.2. Employee Assignment. To the extent permissible under Applicable Law, each Party will cause each employee and contractor conducting work on such Party’s behalf under this Agreement to sign a contract that (i) compels prompt disclosure to the Party of all Ironwood Technology, Partner Technology, Joint Technology, as applicable, conceived or reduced to practice by such employee or contractor during any performance under this Agreement, (ii) automatically assigns to the Party all right, title and interest in and to all such Technology and all Patent Rights disclosing or claiming such Technology, and (iii) obligates such persons to similar obligations of confidentiality as set forth in this Agreement. Each 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 patent purposes to properly reflect all work done.

7.3. Intellectual Property Working Group. The Parties will promptly establish an intellectual property working group comprised of at least one senior patent attorney from each Party, together with research and development personnel and such other representatives of the Parties as the Parties may determine to be appropriate from time to time, to manage and review the patent strategy for inventions made in the course of the Development and to determine patent strategy relating to the Collaboration Patent Rights, to the extent such Collaboration Patent rights are necessary or useful in the Territory to Manufacture, Develop or Commercialize the Licensed Compound or Product.

7.4. Prosecution and Maintenance of Patent Rights.

7.4.1. Patent Prosecution and Maintenance. Each of Ironwood and Partner will be primarily responsible for the preparation, filing, prosecution and maintenance of the Ironwood Patent Rights and the Partner Patent Rights, respectively; provided that: (i) each Party will provide the other with advance copies of, and a reasonable opportunity to comment upon, proposed patent filings in the Territory and prosecution strategies and proposed correspondence with patent offices in the Territory undertaken pursuant to any such filings, and will consider comments received in good faith and will not unreasonably reject such comments, except that Ironwood will not be obligate to provide Partner with advance copies of proposed patent filings, related prosecution strategies or proposed correspondence for Forest Patent Rights; (ii) Ironwood will be primarily responsible for the preparation, filing, prosecution and maintenance of the Partner Patent Rights outside the Territory, but Ironwood will provide Partner with advance copies of, and a reasonable opportunity to comment upon, proposed patent filings, related prosecution strategies and proposed correspondence with patent officials outside the Territory relating to any such patents and will consider comments received in good faith and will not unreasonably reject such comments; and (iii) correspondence or other communications or actions which relate to the validity of Collaboration Patent Rights, to the extent such Collaboration Patent Rights are necessary or useful in the Territory to Manufacture, Develop or Commercialize a Collaboration Compound or Product in the Territory, that are made during the course of an action before a national or regional patent office in the Territory or national court in the Territory will require the mutual approval of both Parties. A Party providing comments in accordance with this Section will provide such comments expeditiously and in any event in reasonably sufficient time to meet any filing deadline communicated to it by the other Party. The Party receiving any such patent application and correspondence will maintain such information in confidence, except for patent applications that have been published and official correspondence that is publicly available.

7.4.2. Joint Patent Rights. The intellectual property working group established under Section 7.3 will designate which Party will be responsible for preparing, filing, prosecuting and maintaining Joint Patent Rights. Irrespective of which Party is responsible for filing, prosecuting and maintaining Joint Patent Rights, Partner and Ironwood will equally share the costs for filing, prosecuting and maintaining Joint Patent Rights in the Territory.

7.4.3. Reversion Rights. If a Party decides not to file, prosecute or maintain a Patent Right covering, as applicable, Ironwood Technology, Partner Technology or Joint Partner Technology, to the extent such Technology is necessary or useful to Manufacture, Develop or Commercialize the Licensed Compound or Product, with respect to Ironwood Technology within the Territory and with respect to Partner Technology whether within or outside of the Territory, it will give the other Party reasonable notice to that effect

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

sufficiently in advance of any deadline for any filing with respect to such Patent Right to permit the other Party to carry out such activity. After such notice, the other Party may file, prosecute and maintain the Patent Right, and perform such acts as may be reasonably necessary for the other Party to file, prosecute or maintain such Patent Right, at its sole cost and expense. If such other Party does so elect, then the Party which has elected not to pursue such filing, prosecution or maintenance will provide such cooperation to the other Party, including the execution and filing of appropriate instruments, as may reasonably be requested to facilitate the transition of such patent activities, and will assign all of its right, title and interest to such patent, other than its rights thereto provided by this Agreement, to the Party electing to pursue such patent activities.

7.4.4. Patent Term Extensions. The Parties agree to cooperate in the selection of the appropriate Ironwood Patent Rights, Partner Patent Rights or Joint Patent Rights as listed in the patent information section of the Product NDA for filing to obtain a patent term extension pursuant to all applicable laws and regulations (“Patent Term Extension”), including without limitation supplementary protection certificates and any other extensions that are now or become available in the future wherever applicable to Patent Rights that are applicable to the Product.

7.5. Trademarks.

7.5.1. Product Trademark. Until such time as the Parties determine that the launch by a Third Party of a generic equivalent of the Product is imminent in the Territory (on a country-by-country basis, and based upon objective evidence shared and discussed by both Parties), all Products will be sold in the Territory under the Trademarks selected by the JCC with advice from the Parties’ intellectual property counsel. No such Trademark will be used outside of the country as to which it has been approved for use by the JCC or outside the Territory, unless otherwise agreed by the Parties in writing. The Parties acknowledge and agree that trademarks developed or used in connection with the Forest Agreement may not be used by the Parties in the Territory unless agreed to by Ironwood and Forest in writing. Ironwood owns such Trademarks subject to the license granted to Partner herein, and is responsible for the filing, prosecution and maintenance of such Trademarks in the applicable country or countries within the Territory. If Ironwood decides not to file, prosecute or maintain a Trademark in a country of the Territory, it will give Partner reasonable notice to that effect sufficiently in advance of any deadline for any filing with respect to such Trademark in such country to permit Partner to carry out such activity. After such notice, Partner may file, prosecute and maintain such Trademark in such country.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

7.5.2. Trademark Use. The manner of use of the Trademarks will be subject to periodic review by the JCC. Neither Party will use the Trademarks in a way that is inconsistent with the usage instructions approved by the JCC, and neither Party will use a trademark confusingly similar to one of the Trademarks with any of its other products or, except as otherwise provided herein, use the Trademarks in combination with its other trademarks in a manner which would create combination marks. The Parties will utilize the Trademarks within the Territory only in accordance with this Agreement.

7.5.3. Party Name on Product Promotional Material. Subject to Applicable Law, all Product promotional material in the Territory will include Ironwood’s trade name, trademark, and other logos requested by Ironwood (the “Ironwood House Marks”) in a manner that has equal prominence with Partner’s marks. To effectuate the purposes of this Agreement, Ironwood hereby grants to Partner a royalty free license, to use and display the Trademarks, and the Ironwood House Marks in connection with the Commercialization of a Product in the Field, with respect to the Trademarks in the Territory, and with respect to the Ironwood House Marks in the U.S., and all in accordance with this Agreement. All goodwill arising from the use of such Trademarks and Ironwood House Marks will inure to the benefit of Ironwood.

7.6. Enforcement of Technology Rights.

7.6.1. Notice. If Ironwood or Partner becomes aware that any Ironwood Technology, Partner Technology, in each such case, which Technology is necessary or useful in the Territory to Manufacture, Develop or Commercialize the Licensed Compound or Product, or Joint Technology is infringed or misappropriated by a Third Party in the Territory in the Field or is subject to a declaratory judgment action arising from such infringement (collectively, an “Infringement”), Ironwood or Partner, as the case may be, will promptly notify the other Party.

7.6.2. Enforcement. The Party that owns the Technology which is the subject of the Infringement will have the first right (but not the obligation), to enforce such Technology against such Infringement, provided that in the event Technology owned by both Parties is the subject of the Infringement, the Parties will cooperate and act in concert to enforce their Technology against such Infringement; provided, further, that (i) the other Party will have the right to join such proceeding at any time at its own expense (subject to the provisions of Section 7.6.3) and will do so at any time if it is deemed to be a necessary Party by the tribunal in which the Infringement is being prosecuted, and (ii) neither Party will admit the invalidity or unenforceability of any Collaboration Technology which Collaboration Technology is necessary or useful in the Territory to Manufacture, Develop or Commercialize the Licensed

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Compound or Product or other Technology owned solely by or jointly with the other Party without the other Party’s prior written consent. In the event the Party with the first right to control an action or proceeding pursuant to this Section declines to prosecute the infringing technology or to defend such claim within 90 days (or such shorter period as may be required to comply with legal or regulatory deadlines which relate to such infringement) of becoming aware thereof, the other Party will have the right to so enforce or defend. Irrespective of which Party controls an action pursuant to this Section, the Parties will collaborate in the choice of counsel with respect to such action and the comments of the other Party will not be unreasonably rejected with respect to strategic decisions and their implementation with respect to such action. In furtherance of the foregoing, the Party responsible for any such action will keep the other Party reasonably informed, in person or by telephone, regarding the status and costs of such action or proceeding prior to and during any such enforcement. Neither Party will settle any such action without the written consent of the other Party, such consent not to be unreasonably withheld. Neither Party will incur any liability to the other as a consequence of such litigation or any unfavorable decision resulting therefrom, including any decision holding any of the Ironwood Technology, Partner Technology, or Joint Technology invalid, not infringed, not misappropriated or unenforceable.

7.6.3. Costs and Recoveries.

(a) If the Party who did not initiate the action against an Infringement under Section 7.6.2 (the “Non-Initiating Party”) joins the other Party (the “Initiating Party”) in action against an Infringement, then the costs of such prosecution or defense of validity, and the proceeds of any awards, judgments or settlements obtained in connection with an Infringement in the Territory will be [**].

(b) If the Non-Initiating Party does not join the Initiating Party in an action against an Infringement, then the Initiating Party will control the Infringement and the proceeds of any awards, judgments, or settlements obtained in connection with the Infringement in the Territory will [**].

7.7. Third Party Claims.

7.7.1. Third Party Claims - Course of Action. If the Development, Commercialization or Manufacture of a Product under this Agreement is alleged by a Third Party to infringe a Third Party’s patent right(s) or misappropriate a Third Party’s trade secret, the Party becoming aware of such allegation will promptly notify the other Party thereof, in writing, reasonably detailing the claim.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

7.7.2. Third Party Suit. If a Third Party sues a Party (the “Sued Party”) alleging that the Sued Party’s or the Sued Party’s Sublicensees’, Development, Manufacture or Commercialization of the Licensed Compound or the Product infringes or will infringe said Third Party’s patent right(s) or misappropriates said Third Party’s trade secret, then upon the Sued Party’s request and in connection with the Sued Party’s defense of any such Third Party suit, the other Party will provide reasonable assistance to the Sued Party for such defense and will join such suit if deemed a necessary party. The Sued Party will keep the other Party, if such other Party has not joined in such suit, reasonably informed on a quarterly basis, in person or by telephone, prior to and during the pendency of any such suit. The Sued Party will not admit the invalidity of any patent within the Ironwood Patent Rights, the Partner Patent Rights or the Joint Patent Rights, nor settle any such suit, without written consent of the other Party, such consent not to be unreasonably withheld. Subject to the Parties’ respective indemnity obligations pursuant to Section 9.1 and 9.2, all litigation expenses, including settlement costs, royalties paid in settlement of any such suit, and the payment of any damages to the Third Party, will be paid by [**].

7.8. Patent Marking. Each Party agrees to xxxx and have its Affiliates and all Sublicensees xxxx all Products (or their containers or labels) sold pursuant to this Agreement in accordance with the applicable statutes or regulations in the country or countries of manufacture and sale thereof.

7.9. Patent Certifications. Each Party will immediately give written notice to the other of any certification of which it becomes aware has been filed pursuant to any foreign equivalent to 21 U.S.C. § 355(b)(2)(A) or § 355(j)(2)(A)(vii) (or any amendment or successor statute thereto) claiming that the Ironwood Patent Rights, Partner Patent Rights, or Collaboration Patent Rights covering the Product are invalid or that infringement will not arise from the manufacture, use or sale in the Territory of such Third Party product by a Third Party. If Partner decides not to bring infringement proceedings against the Third Party making such a certification with respect to any Product, Partner will give notice to Ironwood of its decision not to bring suit within ten business days after receipt of notice of such certification (or, if the time period permitted by law is less than 20 business days, within half of the time period permitted by law for Partner to commence such action) and Ironwood may then, but will not be obligated to, bring suit against the Third Party that filed the certification. Any suit by either Party may be in the name of either or both Parties, as may be required by law. For this purpose, the Party not bringing suit will execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the Party bringing suit.

7.10. No Implied Licenses. Except as expressly set forth in this Agreement, no right or license under any Ironwood Technology or Partner Technology is granted or will be granted by implication as a result of the respective rights of the Parties under this Agreement. All such rights or licenses are or will be granted only as expressly provided in this Agreement.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

7.11. Privileged Communications. In furtherance of this Agreement, it is expected that Partner and Ironwood will, from time to time, disclose to one another privileged communications with counsel, including opinions, memoranda, letters and other written, electronic and verbal communications. Such disclosures are made with the understanding that they will remain confidential, they will not be deemed to waive any applicable attorney-client privilege and that they are made in connection with the shared community of legal interests existing between Ironwood and Partner, including the community of legal interests in avoiding infringement of any valid, enforceable patents of Third Parties and maintaining the validity of Ironwood Patent Rights, Partner Patent Rights and Joint Patent Rights.

8. TERM AND TERMINATION

8.1. Term. The term of this Agreement will commence on the Effective Date and, unless earlier terminated as provided in this Section 8, will continue in full force and effect on a Product-by-Product and country-by-country basis until Partner is no longer Developing or Commercializing such Product in such country.

8.2. Termination for Cause.

8.2.1. Termination for Material Breach. This Agreement may be terminated effective immediately to the extent set forth in the last sentence of this Section by written notice by either Party at any time during the Term if the other Party materially breaches this Agreement, which breach remains uncured for [**] days measured from the date written notice of such breach is given to the breaching Party, which notice will specify the nature of the breach and demand its cure; provided, however, that if such breach is not capable of being cured within the stated period and the breaching Party uses Commercially Reasonable Efforts to cure such breach during such period and presents a mutually agreeable remediation plan for such breach, this Agreement will not terminate and the cure period will be extended for such period provided in the remediation plan as long as the breaching party continues to use Commercially Reasonable Efforts to pursue the cure as provided in such remediation plan. Notwithstanding anything to the contrary set forth in this Agreement but subject to the limitations set forth in Section 9.5, termination will not be deemed to relieve a defaulting party from any liability arising from such default. The non-breaching Party may terminate this Agreement pursuant to this Section 8.2.1 (i) in the event of a material breach that is specifically related to a country in the Territory and such country is not a Major Country, only with respect to such country, (ii) in the event of a material breach that is specifically related to a Major Country, with respect to such country or as to this Agreement in its entirety, at the election of the non-breaching Party and (iii) in the event of a material breach that does not relate specifically to a particular country in the Territory, as to this Agreement in its entirety.

(e) Partner will furnish Ironwood with reasonable cooperation to assure a smooth transition of any clinical or other studies in progress related to the Licensed Compound or Product which Ironwood determines to continue in compliance with Applicable Law and ethical guidelines applicable to the transfer or termination of any such studies. In addition, Partner will return all Ironwood Confidential Information to Ironwood; and

(f) Until termination is effective, Partner will continue to perform its obligations under the Development Plan and the Commercialization Plan then in effect, except with respect to activities that Ironwood elects to discontinue.

Sections 8.2.3(a) will be effective upon any such termination, and Sections 8.2.3(b), 8.2.3(c), 8.2.3(d), 8.2.3(e) and 8.2.3(f) will be effective upon such termination or Ironwood’s earlier election following a notice of termination.

8.2.4. Effects of Termination by Partner. If Partner is entitled to terminate this Agreement pursuant to Section 8.2.1 or 8.2.2, Partner may terminate this Agreement, in which case all licenses granted by Ironwood to Partner will terminate and neither Party will have any further contractual obligations to the other except to the extent of provisions which survive the termination of this Agreement by their respective terms and obligations accrued but remaining outstanding as of the effectiveness of termination.

8.2.5. Bankruptcy. This Agreement may be terminated by written notice by either Party at any time during the Term of this Agreement if the other Party will file in any court or agency, pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of that Party or of its assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party will be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not dismissed within 60 days after the filing thereof, or if the other Party proposes or is a Party to any dissolution or liquidation, or if the other Party makes an assignment for the benefit of its creditors.

8.3. Termination for Convenience. Prior to its expiration, this Agreement may be terminated in its entirety at any time by Partner effective upon at least [**] days prior written notice to Ironwood for any reason. If Partner terminates for a material safety issue, Partner will provide all assistance reasonably requested by Ironwood for at least [**] days after the effective date of such termination to identify, further characterize, and fully document such safety issue, and will provide such other assistance as may be reasonably useful or necessary for Ironwood to continue with the development or commercialization

8.4.2. Consequences of a Change of Control.

(a) In the event that Partner is subject to a Change of Control which could reasonably be expected to lead to an Impairment (as defined below), Partner will notify Ironwood at least [**] days prior to the closing of such transaction, and Ironwood may elect, in its sole discretion, to (i) continue this Agreement in accordance with its terms, (ii) terminate this Agreement on [**] months notice, during which period this Agreement would continue in effect in accordance with its terms, or (iii) terminate this Agreement effective upon [**] days written notice of termination, in each of cases (ii) and (iii) such notice to be delivered within [**] days after the Fair Market Value is determined pursuant to this Section 8.4.2(a). Within [**] days following Ironwood’s receipt of notice from Partner of a Change of Control, Ironwood will provide notice to Partner requesting a determination of the Fair Market Value of the Product rights subject to acquisition by Ironwood upon a termination pursuant to this Section 8.4.2(a), and the failure to so request such valuation will be deemed the election to continue this Agreement in accordance with its terms. Such determination must be made by the Parties in good faith, and if such determination is not made within [**] days of the request, then as determined by a Valuation Panel. In connection with such termination, Ironwood will be required to pay Partner an amount equal to the Fair Market Value of the Product rights reacquired by Ironwood in a lump sum payment within [**] days of the effective date of the termination.

(b) In the event that Partner is subject to a Change of Control and the other party to the Change of Control is Forest, then Ironwood will have the right to terminate this Agreement on [**] days notice.

(c) For purposes of this Section 8.4.2, an “Impairment” will only be deemed to occur if (a) it is reasonably anticipated that the entity resulting from such Change of Control will be unable to perform its obligations in accordance with the terms of this Agreement, as reasonably determined based on objective criteria available to both Parties, including without

limitation, the new entity’s financial position and product pipeline, (b) the product line of the entity which results from the Change of Control includes a product which is indicated for the treatment of IBS-C, CC, OIC (unless as to any such indication, the JDC has determined not to pursue Development for such indication) or any other indication for which the Product is then being Commercialized in the Territory pursuant to this Agreement.

8.5. Survival of Certain Obligations. Expiration or termination of this Agreement will not relieve the Parties of any obligation accruing before such expiration or termination. The provisions of this Agreement that must, by their nature, survive expiration or termination of this Agreement to give effect to their intent, will so survive, including without limitation Sections 5, 8, and 9. Any expiration or early termination of this Agreement will be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement before termination.

9. PRODUCT LIABILITY, INDEMNIFICATION, AND INSURANCE

9.1. Indemnification by Ironwood. Ironwood will indemnify, defend and hold harmless Partner, its Affiliates, and each of its and their respective employees, officers, directors agents and permitted Sublicensees (each, a “Partner Indemnified Party”) from and against any and all losses, damages, liabilities, settlements, penalties, fines, and expenses (including, without limitation, reasonable attorneys’ fees and expenses) (collectively, “Liability”) that the Partner Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of (i) any Ironwood representation or warranty set forth in this Agreement being untrue in any material respect or (ii) any material breach by Ironwood of any of its covenants or obligations hereunder, except to the extent caused by the gross negligence or willful misconduct of Partner or any Partner Indemnified Party, or by breach of this Agreement by Partner.

9.2. Indemnification by Partner. Partner will indemnify, defend and hold harmless Ironwood, its Affiliates, Sublicensees, distributors and each of its and their respective employees, officers, directors and agents (each, an “Ironwood Indemnified Party”) from and against any and all Liabilities that the Ironwood Indemnified Party may be required to pay to one or more Third Parties to the extent resulting from or arising out of:

(a) any Partner representation or warranty set forth in this Agreement being untrue in any material respect or a material breach by Partner of any of its covenants or obligations hereunder;

(b) the Development of the Product by Partner hereunder;

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

(d) any recall or withdrawal of the Product in the Field in the Territory, to the extent attributable to acts of Partner,

except in each case, to the extent caused by the gross negligence or willful misconduct of Ironwood or any Ironwood Indemnified Party, or by breach of this Agreement by Ironwood.

9.3. Procedure. Each Party will notify the other in the event it becomes aware of a claim for which indemnification may be sought hereunder or for which Liability is shared pursuant to this Section 9. In case any proceeding (including any governmental investigation) is instituted involving any Party in respect of which indemnity may be sought pursuant to this Section 9, such Party (the “Indemnified Party”) will promptly notify the other Party (the “Indemnifying Party”) in writing and the Indemnifying Party and Indemnified Party will meet to discuss how to respond to any claims that are the subject matter of such proceeding. The Indemnifying Party, upon request of the Indemnified Party, will retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and will pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party will have the right to retain its own counsel, but the fees and expenses of such counsel will be at the expense of the Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party will 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. All such fees and expenses incurred pursuant to Section 9.1 or 9.2 will be reimbursed as they are incurred. The Indemnifying Party will not be liable for any settlement of any proceeding unless effected with its written consent. The Indemnifying Party will not, without the written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which the Indemnified Party is, or arising out of the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on claims to which the indemnity relates that are the subject matter of such proceeding.

9.4. Insurance. Each Party further agrees to use Commercially Reasonable Efforts to obtain and maintain, during the Term of this Agreement, commercial general liability insurance, including products liability insurance, with reputable and financially secure insurance carriers to cover its indemnification obligations under Sections 9.1 or 9.1, as applicable, or self-insurance, with limits of not less than [**] million dollars per occurrence and [**] million dollars in the aggregate ($[**] in the aggregate from and after Commercial Launch).

9.5. Liability Limitations. NOTWITHSTANDING THE FOREGOING, IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE, OR

10. MISCELLANEOUS.

10.1. Governing Law; Jurisdiction; Dispute Resolution.

10.1.1. Governing Law. The interpretation and construction of this Agreement will be governed by the laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

10.1.2. Dispute Resolution. In the event of a dispute arising out of or relating to this Agreement, either Party will provide written notice of the dispute to the other, in which event the dispute will be referred to the executive officers designated below or their successors, for attempted resolution by good faith negotiations within 30 days after such notice is received. The designated officers are initially as follows:

For Ironwood: Its Chief Executive Officer or his designate

For Partner: Its Chief Executive Officer or his designate

In the event the designated executive officers do not resolve such dispute within the allotted 30 days, either Party may, after the expiration of the 30 day period, seek to resolve the dispute through arbitration in accordance with Section 10.1.3. Notwithstanding the preceding, the Parties acknowledge that the failure of the JDC to reach consensus as to any matter, which failure does not involve a breach by a Party of its obligations hereunder, will not be deemed a dispute which may be referred for resolution by arbitration hereunder.

10.1.3. Arbitration.

(a) Claims. Any claim, dispute, or controversy of whatever nature arising between the Parties out of or relating to this Agreement that is not resolved under Section 10.1.2 within the required 30 day time period, including without limitation, any action or claim based on tort, contract, or statute (including any claims of breach or violation of statutory or common law protections from discrimination, harassment and hostile working environment), or concerning the interpretation, effect, termination, validity, performance and/or breach of this Agreement (“Claim”), will be resolved by final and binding arbitration before a panel of three experts with relevant industry experience (the “Arbitrators”). One Arbitrator will

be chosen by Ironwood and one Arbitrator will be chosen by Partner within 15 days from the notice of initiation of arbitration. The third Arbitrator will be chosen by mutual agreement of the Arbitrator chosen by Ironwood and the Arbitrator chosen by Partner within 15 days of the date that the last of such Arbitrators were appointed. The Arbitrators will be administered by the International Chamber of Commerce (the “Administrator”) in accordance with its then existing arbitration rules or procedures regarding commercial or business disputes. The arbitration will be held in New York, New York. The Arbitrators will be instructed by the Parties to complete the arbitration within 90 days after selection of the final Arbitrator.

(b) Arbitrators’ Award. The Arbitrators will, within 15 calendar days after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The decision or award rendered by the Arbitrators will be final and non-appealable, and judgment may be entered upon it in accordance with applicable law in the State of New York or any other court of competent jurisdiction. The Arbitrators will be authorized to award compensatory damages, but will NOT be authorized (i) to award non-economic damages, such as for emotional distress, pain and suffering or loss of consortium, (ii) to award punitive damages, or (iii) to reform, modify or materially change this Agreement or any other agreements contemplated hereunder; provided, however, that the damage limitations described in parts (i) and (ii) of this sentence will not apply if such damages are statutorily imposed.

(c) Costs. Each Party will bear its own attorney’s fees, costs, and disbursements arising out of the arbitration and the costs of the arbitrator selected by it, and will pay an equal share of the fees and costs of the third arbitrator; provided, however, the Arbitrators will be authorized to determine whether a party is the prevailing party, and if so, to award to that prevailing party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the Administrator and the Arbitrators.

(d) Compliance with this Agreement. Unless the Parties otherwise agree in writing, during the period of time that any arbitration proceeding is pending under this Agreement, the Parties will continue to comply with all those terms and provisions of this Agreement that are not the subject of the pending arbitration proceeding.

(e) Injunctive or Other Equity Relief. Nothing contained in this Agreement will deny any Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing arbitration proceeding.

10.2. Force Majeure. No liability will result from, and no right to terminate will arise, in whole or in part, based upon any delay in performance or non-performance, in whole or in part, by either of the Parties to this Agreement to the extent that such delay or non-performance is caused by an event of Force Majeure. “Force Majeure” means an event that is beyond a non-performing Party’s reasonable control, including an act of God, act of the other Party, war, riot, civil commotion, terrorist act, malicious damage, epidemic, quarantine, fire, flood, storm, natural disaster or compliance with any law or governmental order, rule, regulation or direction, whether or not it is later held to be invalid or inapplicable. The Force Majeure Party will within ten days of the occurrence of the Force Majeure event, give written notice to the other Party stating the nature of the Force Majeure event, its anticipated duration and any action being taken to avoid or minimize its effect. Any suspension of performance will be of no greater scope and of no longer duration than is reasonably required and the Force Majeure Party will use reasonable effort to remedy its inability to perform; provided, however, if the suspension of performance continues or is anticipated to continue for 30 days after the date of the occurrence, the unaffected Party will have the right but not the obligation to perform on behalf of the Force Majeure Party for a period of such Force Majeure and such additional period as may be reasonably required to assure a smooth and uninterrupted transition of such activities. If such failure to perform would constitute a material breach of this Agreement in the absence of such event of Force Majeure, and continues for one year from the date of the occurrence and the Parties are not able to agree on appropriate amendments within such period, such other Party will have the right, notwithstanding the first sentence of this Section 10.2, to terminate this Agreement immediately by written notice to the Force Majeure Party, in which case neither Party will have any liability to the other except for those rights and liabilities that accrued prior to the date of termination and the consequences of termination pursuant to Sections 8.2.3 or 8.2.4, as applicable, as if such termination was a termination as to which such consequences applied.

10.3. Additional Approvals. Partner and Ironwood will cooperate and use respectively all reasonable efforts to make all other registrations, filings and applications, to give all notices and to obtain as soon as practicable all governmental or other consents, transfers, approvals, orders, qualifications authorizations, permits and waivers, if any, and to do all other things necessary or desirable for the consummation of the transactions as contemplated hereby. Neither Party will be required, however, to divest or out-license products or assets or materially change its business if doing so is a condition of obtaining any governmental approvals of the transactions contemplated by this Agreement.

10.4. Waiver and Non-Exclusion of Remedies. A Party’s failure to enforce, at any time or for any period of time, any provision of this Agreement, or to exercise any right or remedy will not constitute a waiver of that provision, right or remedy or prevent such Party from enforcing any or all provisions of this Agreement and exercising any rights or remedies. To be effective any waiver must be in writing. The rights and remedies provided in this Agreement are cumulative and do not exclude any other right or remedy provided by law or otherwise available except as expressly set forth in this Agreement.
