(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 12.3 within the required [**] time period, including 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 (a “Claim”), shall be resolved by final and binding arbitration before a panel of three (3) experts with relevant industry experience (the “Arbitrators”).  One (1) Arbitrator shall be chosen by Allergan and one (1) Arbitrator shall be chosen by Ironwood within [**] from the notice of initiation of arbitration.  The third (3rd) Arbitrator shall be chosen by mutual agreement of the Arbitrator chosen by Allergan and the Arbitrator chosen by Ironwood within [**] of the date that the last of such Arbitrators was appointed.  The Arbitrators shall 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 shall be held in [**] if requested by Allergan and in [**] if requested by Ironwood.  The Arbitrators shall be instructed by the Parties to complete the arbitration within [**] after selection of the third (3rd) Arbitrator.

(b)Arbitrators’ Award.  The Arbitrators shall, within [**] 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 shall be final and non-appealable, and judgment may be entered upon it in accordance with Applicable Laws in the State of [**] or [**], as applicable, or any other court of competent jurisdiction.  The Arbitrators shall be authorized to award compensatory damages, but shall 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 limitations described in the foregoing clauses (i) and (ii) shall not apply if such damages are statutorily imposed.

(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 shall continue to comply with the 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 shall 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.

12.3Dispute Resolution.  In the event of a dispute arising out of or relating to this Agreement, either Party shall provide written notice of the dispute to the other Party, in which event the dispute shall be referred to the executive officers designated below or their successors for attempted resolution by good faith negotiations within [**] after such notice is received:

In the event that the designated executive officers do not resolve such dispute within the allotted [**], either Party may, after expiration of such [**] period, seek to resolve the dispute through arbitration in accordance with Section 12.2.

12.4Force Majeure.  No liability shall result from, and no right to terminate shall arise, in whole or in part, based upon any delay in the performance or non-performance (other than failure to pay any amounts

due under this Agreement as and when due), in whole or in part, by either Party to the extent that such delay or non-performance is caused by a Force Majeure.  For purposes of this Section 12.4, “Force Majeure” means an event that is beyond the reasonable control of the non-performing Party (the “Force Majeure Party”), including an act of God, act of the other Party, strike, lock-out or other industrial/labor dispute, 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 shall, within [**] of the occurrence of a Force Majeure, give written notice to the other Party stating the nature of such Force Majeure, its anticipated duration and any action being taken to avoid or minimize its effect.  Any suspension of performance shall be of no greater scope and of no longer duration than is reasonably required, and the Force Majeure Party shall use reasonable effort to remedy its inability to perform; provided,  however, that if the suspension of performance continues or is anticipated to continue for [**] after the date of the occurrence, the unaffected Party shall have the right but not the obligation to perform on behalf of the Force Majeure Party for a period of the 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 [**] of this Agreement in the absence of the Force Majeure and continues for [**] from the date of the occurrence, and the Parties are not able to agree on appropriate amendments within such period, such other Party shall have the right, notwithstanding the first sentence of this Section 12.4, to terminate this Agreement immediately by written notice to the Force Majeure Party, in which case neither Party shall have any liability to the other except for those rights and liabilities that accrued prior to the date of termination.

12.5Additional Approvals.  The Parties shall reasonably cooperate and use 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 contemplated hereby.

12.6Waiver 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  hereunder, shall not constitute a waiver of such provision, right or remedy or prevent such Party from enforcing any or all provisions of this Agreement and exercising any of its rights or remedies hereunder.  To be effective any waiver must be in writing.  The respective rights and remedies of the Parties provided herein are cumulative and do not exclude any other right or remedy of the Parties provided by law or otherwise available except as expressly set forth herein.

12.7Notices.

(a)Notice Requirements.  Any notice, request, demand, waiver, consent, approval or other communication permitted or required under this Agreement shall be in writing, shall refer specifically to this Agreement and shall be deemed given only if delivered by hand or sent by internationally recognized overnight delivery service that maintains records of delivery, addressed to the Parties at their respective addresses specified in subsection (b) below or to such other address as the Party to whom notice is to be given may have provided to the other Party in accordance with this Section 12.7.  Such notice shall be deemed to have been given as of the date delivered by hand or on the second (2nd) Business Day (at the place of delivery) after deposit with an internationally recognized overnight delivery service.  This Section 12.7 is not intended to govern the day-to-day business communications necessary between the Parties in performing their obligations under the terms of this Agreement.
