Any undisputed overpayment of royalties by Trevi revealed by an examination will be paid by Penwest within [**] of Penwest’s receipt of the applicable report.

(d) Right to Enforce Know-how.

14


(f) Recoveries.

(i) If Trevi initiates suit as permitted in accordance with Section 5.2(b) or, with respect to Penwest Know-how, in the same manner as set forth in Section 5.2(b), any damages, settlements, accounts of profits, or other financial compensation actually paid to Trevi by a Third Party based upon such suit, after deducting Trevi’s actual out of pocket expenses (including reasonable attorneys’ fees and expenses) incurred in pursuing such suit (such net amount, the “Recovery”), will be treated as Sublicense Income, and will be subject to the payment obligations under Section 4.5, with Trevi retaining the balance after such payment.

(ii) If Penwest initiates suit pursuant to Section 5.2(c) or with respect to Penwest Know-how, in the same manner as set forth in Section 5.2(c), Penwest may retain any damages, settlements, accounts of profits, or other financial compensation recovered from a Third Party based upon such suit.

ARTICLE X

DISPUTE RESOLUTION

10.1 Referral of Unresolved Matters to Senior Executives. In the event that the Parties are unable to resolve a dispute within [**] from the date such dispute is first brought to the other Party’s attention, the matter shall be referred to the Chief Executive Officer of Trevi and a senior executive of Penwest or its Affiliate to be resolved by negotiation in good faith as soon as is practicable but in no event later than [**] after referral.

10.2 Arbitration. Any dispute, controversy or claim arising out of or relating to this Agreement which the Parties have not resolved under Section 10.1, will be decided by arbitration in accordance with the Rules of the American Arbitration Association for Commercial Arbitration in effect at the time the dispute arises, unless the Parties hereto mutually agree otherwise. To the extent such rules are inconsistent with this provision, this provision will control. The following rules will apply to any such arbitration:

(a) Any demand for arbitration must be made in writing to the other Party.

(b) There will be three arbitrators, one of whom shall be appointed by each Party and a third of whom shall be the chairman of the panel and be appointed by mutual agreement of the two arbitrators appointed by the Parties. If the two arbitrators cannot agree on the appointment of the third arbitrator within [**], then the AAA shall select the arbitrator. Any arbitration involving patent rights, other intellectual property rights or intellectual property will be heard by arbitrators who are expert in such areas.

(c) The arbitration will be held in Philadelphia, Pennsylvania, or such other place as the Parties agree. The arbitrators will apply the substantive law of the Commonwealth of Pennsylvania in accordance with Section 11.1, without regard to conflicts of laws and except that the interpretation and enforcement of this arbitration provision will be governed by the Federal Arbitration Act, 9 U.S.C. Section 1 et. seq.

 

22


(d) Neither Party will have the right independently to seek recourse from a court of law or other authorities in lieu of arbitration, but each Party has the right before or during the arbitration to seek and obtain from the appropriate court provisional remedies to avoid irreparable harm, maintain the status quo or preserve the subject matter of the arbitration. There shall be a stenographic record of the proceedings. The decision of the arbitrators will be final and binding upon both Parties. The arbitrators will render a written opinion setting forth findings of fact and conclusions of law.

(e) Each Party will bear its own expenses of the arbitration, including the expenses of its counsel and other experts, except that both Parties shall share equally in the cost of appointed arbitrator.

10.3 Equitable Relief. Notwithstanding anything to the contrary, each of the Parties hereby acknowledges that a breach of their respective obligations under this Agreement may cause irreparable harm and that the remedy or remedies at law for any such breach may be inadequate. Each of the Parties hereby agrees that, in the event of any such breach, in addition to all other available remedies hereunder, the non-breaching Party shall have the right, through the arbitration process described in Section 10.2 or in court, to seek equitable relief to enforce the provisions of this Agreement.

ARTICLE XI

MISCELLANEOUS

11.1 Governing Law and Jurisdiction. The validity, construction and performance of this Agreement will be governed by and construed in accordance with the substantive laws of the Commonwealth of Pennsylvania 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.

11.2 Force Majeure. Neither Party will be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term, other than an obligation to make payments hereunder, when such failure or delay is caused by or results from fire, floods, embargoes, government regulations, prohibitions or interventions, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, acts of God or any other cause beyond the reasonable control of the affected Party to anticipate, prevent, avoid or mitigate (a “Force Majeure Event”); provided that (i) the affected Party provides prompt written notice to the other Party of such failure or delay, (ii) the affected Party uses Commercially Reasonable Efforts to mitigate the effects of the Force Majeure Event, and (iii) the affected Party immediately resumes performance upon cessation of the Force Majeure Event. Notwithstanding the foregoing, any failure or delay in fulfilling a term shall not be considered a result of a Force Majeure Event if it arises from a failure of Trevi or Penwest to comply with applicable laws.

 

23
