Such amounts shall be determined from the books and records of Ipsen, its Affiliates or its sublicensees, as applicable, maintained in accordance with applicable Accounting Standards, consistently applied.

In the case of any sale of Licensed Products for consideration other than cash, such as barter or countertrade, Net Sales shall be calculated on average sales price for the applicable Licensed Product(s) in the applicable country in the entire applicable year. In the case that Licensed Product(s) are sold as part of a bundle for less than the average sales price for the applicable Licensed Product(s) in the applicable country in the entire applicable year, Net Sales shall be based upon the higher of (x) the discounted price for which such Licensed Product(s) are actually sold or (y) the discounted price for which such Licensed Product(s) would be sold if the discounts applied to all products in the bundle were applied equally to such products in proportion to their respective average sales prices in the applicable country in the entire applicable year.

Sales of Licensed Products between Ipsen and its Affiliates or its sublicensees, or among such Affiliates and sublicensees, shall be disregarded for purposes of calculating Net Sales hereunder, except for sales to Affiliates or sublicensees that are the intended end user.

In the event a Licensed Product is sold as part of a Combination Product (as defined below), the Net Sales from the Combination Product, for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of the Combination Product during the applicable royalty reporting period by the fraction A/A+B, where A is the average sale price of the Licensed Product when sold separately in finished form, and B is the average sale price of the other product(s) included in the Combination Product when sold separately in finished form, in each case during the applicable royalty reporting period or, if sales of both the Licensed Product and the other product(s) did not occur in such period, then in the most recent royalty reporting period in which sales of both occurred.

In the event that such average sale price cannot be determined for both the Licensed Product and all other products(s) included in the Combination Product, Net Sales for the purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the fraction of C/C+D where C is the fair market value of the Licensed Product and D is the fair market value of all other pharmaceutical product(s) included in the Combination Product. In such event, Ipsen shall in good faith make a determination of the respective fair market values of the Licensed Product and all other pharmaceutical products included in the Combination Product, and shall notify Lexicon of such determination and provide Lexicon with data to support such determination. Lexicon shall have the right to review such determination and supporting data, and to notify Ipsen if it disagrees with such determination. If Lexicon does not agree with such determination and if the Parties are unable to agree in good faith as to such respective fair market values, then such matter shall be referred to the Executive Officers for resolution pursuant to Section 13.1 and, if the Executive Officers are unable to resolve such matter in accordance with Section 13.1, such matter shall be referred to binding arbitration for resolution pursuant to Section 13.2.

Section 9.3 Third Party Infringement.

(a) Notice. Each Party shall promptly report in writing to the other Party during the Term any (i) known or suspected infringement of any issued claims within the Licensed Patent Rights by a Third Party, or (ii) any known or suspected misappropriation of any of the Licensed Technology by a Third Party. In the event such known or suspected infringement or misappropriation involves the manufacture, sale, offer for sale, use, or importation in the Licensed Territory of the Compound or a Licensed Product being developed or commercialized by Ipsen hereunder (“Competitive Infringement”), the reporting Party shall provide the evidence in its possession regarding such Competitive Infringement to the other Party. Promptly after receipt of a notice of Competitive Infringement, the Parties shall discuss in good faith the Competitive Infringement and appropriate actions that could be taken to end the Competitive Infringement.

Confidential materials omitted and filed separately

with the Securities and Exchange Commission.

Asterisks denote omissions.

(b) Enforcement.

(i) Competitive Infringement. Subject to any rights of and obligations to Lexicon’s Third Party licensors, Ipsen shall have the first right to initiate a suit or take other appropriate action that it believes necessary to end any Competitive Infringement, at Xxxxx’x sole control and expense. If Ipsen fails to initiate a suit or take other appropriate action that it has the initial right to initiate or take to end such Competitive Infringement within [**] (or such shorter period specified below in this Section 9.3(b) or in Section 9.6, if applicable) after becoming aware of the basis for such suit or action, then Lexicon may, in its discretion, initiate a suit or take other appropriate action that it believes necessary to end such Competitive Infringement. The [**] period in the immediately preceding sentence shall be shortened as reasonably necessary to enable Lexicon to initiate a suit or take other appropriate action if, in the absence of such shortening, a loss of rights with respect to such suit or other action would occur (e.g., if a generic pharmaceutical maker files an abbreviated new drug application or analogous application for which the reference listed drug is a Licensed Product and, in order to obtain an automatic stay from the EMA with respect to the approval of such application, a patent infringement suit must be brought within a shorter period of time). The Party filing any such suit or taking any such action shall be responsible for all costs in connection therewith and, therefore, shall control all decision-making related to any such suit or action, subject to Section 9.3(c) below.

(ii) Infringement other than Competitive Infringement. Lexicon shall have the sole right to initiate a suit or take other appropriate action that it believes necessary to end any infringement of the Licensed Patent Rights other than a Competitive Infringement. Lexicon shall notify Ipsen in writing prior to initiating such suit or action, and promptly after receipt of such notice, the Parties shall discuss in good faith the advisability of such suit or action in view of any identified risks to the Licensed Patent Rights and the Licensed Products.

(c) Conduct of Actions. The Party initiating suit or action shall have the sole and exclusive right to select counsel for any suit initiated by it referred to in Section 9.3(b) above. If required under applicable Law in order for the initiating Party to initiate or maintain such suit or action, the other Party shall join as a party to the suit or action. Such other Party shall offer reasonable assistance to the initiating Party in connection therewith at no charge to the initiating Party except for reimbursement of reasonable out-of-pocket expenses incurred in rendering such assistance. The Party filing any such suit or taking any such action shall provide the other Party with an opportunity to make suggestions and comments regarding such suit or action. Thereafter, the Party filing any such suit or taking any such action shall, to the extent permitted by applicable Law, keep the other Party promptly informed, and shall from time to time consult with such other Party regarding the status of any such suit or action and shall provide such other Party with copies of all material documents (i.e., complaints, answers, counterclaims, material motions, orders of the court, memoranda of law and legal briefs, interrogatory responses, depositions, material pre-trial filings, expert reports, affidavits filed in court, transcripts of hearings and trial testimony, trial exhibits and notices of appeal) filed in, or otherwise relating to, such suit or action. The Party not initiating such suit or action shall cooperate with the Party initiating such suit or action to the extent reasonably requested, and shall have the right to participate and be represented in any such suit by its own counsel at its own expense. Neither Party shall conduct any such suit or action in a manner that materially places at risk the scope or validity of any Licensed Patent Right without the prior written approval of the other Party, and neither Party shall settle or compromise any claim or proceeding relating to Licensed Intellectual Property without obtaining the prior written consent of the other Party, such consent not to be unreasonably withheld.

(d) Recoveries. With respect to any suit or action to protect Licensed Intellectual Property referred to in Section 9.3(b) above, any recovery obtained as a result of any such proceeding, by settlement or otherwise, shall be applied in the following order of priority:

(i) first, the Party initiating the suit or action with respect to Licensed Intellectual Property shall be reimbursed for all out-of-pocket costs and expenses in connection with such proceeding paid by such Party and not otherwise recovered; and

(ii) second, any remainder shall be paid [**] percent ([**]%) to the Party initiating such suit or action and [**] percent ([**]%) to the other Party.

Section 9.4 Claimed Infringement.

In the event that a Party becomes aware of any claim or threat of claim that the manufacture, sale, offer for sale, use, or importation of the Compound or any Licensed Product by Lexicon or Ipsen hereunder infringes or misappropriates the intellectual property rights of any Third Party, such Party shall promptly notify the other Party. Each Party shall provide to the other Party copies of any notices it receives from Third Parties regarding any alleged infringement of Third Party Patent Rights or any alleged misappropriation of Third Party Know-How. Such notices shall be provided promptly, but in no event after more than [**] following receipt thereof. In any such instance, the Parties shall cooperate in undertaking an appropriate course of action.

Section 9.5 Patent Invalidity Claim.

(a) If a Third Party at any time asserts a claim that any Licensed Patent Right is invalid or otherwise unenforceable (“Invalidity Claim”), whether as a defense in an infringement action brought by Ipsen or Lexicon pursuant to Section 9.3 or in any declaratory judgment action or otherwise, the Parties shall cooperate with each other in preparing and formulating a response to such Invalidity Claim. Neither Party shall settle or compromise any Invalidity Claim without the consent of the other Party, which consent shall not be unreasonably withheld.

(b) If any Invalidity Claim is brought against Ipsen or Lexicon in any action other than as a defense in any action brought by Ipsen or Lexicon asserting that any Licensed Patent Right is invalid or otherwise unenforceable, the Parties shall bear the costs of defending such Invalidity Claim in the same manner as they bear costs of Patent Prosecution relating to the applicable Licensed Patent Right pursuant to Section 9.2(d).

Section 9.6 Certification Under Drug Price Competition and Patent Restoration Act.

If a Party becomes aware of any certification filed pursuant to (a) 21 U.S.C. §355(b)(2)(A)(iv) or 355(j)(2)(A)(vii)(IV) or (b) any comparable Law under any other jurisdiction, including any amendment or successor statute to any of the foregoing clause (a) or (b), and such certification claims that any Licensed Patent Right or Joint Patent Right, in each case Covering the Compound or a Licensed Product in the Field, is invalid or otherwise unenforceable, or that infringement will not arise from the manufacture, sale, offer for sale, use, or importation of a product by a Third Party (a “Paragraph IV Certification”), such Party shall promptly notify the other Party in writing within [**] after its receipt thereof.

Section 9.7 Patent Marking.

Ipsen agrees to comply with the patent marking statutes in each country in which Licensed Products are sold by Ipsen, its Affiliates or sublicensees.

Section 9.8 Trademark.

(a) Lexicon filed an application for registration of the name “Xermelo” with the Office for Harmonization in the Internal Market and such registration was approved by the EMA on 25 April 2014.

(b) Lexicon shall be responsible for securing and for maintaining at Xxxxx’x expense the Licensed Trademark in the Licensed Territory and shall use Diligent Efforts in that regard. In the event Lexicon is unable to obtain or maintain the Licensed Trademark in some country(ies) in the Licensed Territory, the Parties shall negotiate in good faith concerning the selection of such other trademarks (i.e., back-up names) as may be available for marketing the Licensed Product in those countries.

(c) All rights granted hereunder to Ipsen with respect to the Licensed Trademark shall be exercised, and all Licensed Products bearing the Licensed Trademark shall be manufactured, in accordance with quality standards established by the JCC, which quality standards shall be approved by Lexicon for consistency with the quality standards applied by Lexicon to its own products and the Parties shall reasonably cooperate to enable Lexicon to monitor Xxxxx’x compliance with such quality standards.

(d) Confusion with LX1033. To avoid any confusion or association with its other small molecule inhibitor TPH LX1033, if Lexicon continues to directly or indirectly, or through any Third Party, develop, commercialize, distribute or otherwise exploit LX1033, Lexicon agrees that:

(i) it will not seek Marketing Authorization for LX1033 in the Licensed Territory under:

(A) the Licensed Trademark, or

(B) a tradename that is identical, similar to or is confusingly similar to the Licensed Trademark.

(ii) Following the Effective Date, Lexicon will use reasonable efforts to have the EMA approve the invented name “Xermelo” to apply to the Licensed Product designated under the INN “telotristat etiprate”.

(iii) Lexicon agrees to request an INN for LX1033 other than “telotristat” with the World Health Organization (“WHO”) and a new United States Adopted Name (“USAN”) for LX1033 with the United States Adopted Name Council (“USAN Council”).

(e) The Parties shall cooperate with each other and use Diligent Efforts to protect the Licensed Trademark from infringement by Third Parties in the Licensed Territory. Without limiting the foregoing, each Party shall promptly notify the other Party of any known, threatened or suspected infringement, imitation or unauthorized use of or unfair competition relating to the Licensed Trademark in the Licensed Territory. Lexicon shall have the first right to determine in its discretion whether to and to what extent to institute, prosecute and/or defend any action or proceedings involving or affecting any rights relating to the Licensed Trademark. Upon Lexicon’s reasonable request, Ipsen shall cooperate with and assist Lexicon

in any of Lexicon’s enforcement efforts with respect to the Licensed Trademark. Lexicon shall promptly inform Ipsen if Lexicon elects not to take action against any actual or suspected infringement of the Licensed Trademark in the Licensed Territory, in which case, Ipsen shall then have the right, but not the obligation, to bring or assume control of any such action against the allegedly infringing Third Party as Ipsen determines may be necessary, provided however, that Ipsen shall not enter into any settlement or compromise of any claim relating to the Licensed Trademark without the prior written consent of Lexicon. In the event that Ipsen brings or assumes control of any such action, then Lexicon agrees to reasonably assist Ipsen in connection therewith. In either case, the Party that initiated and prosecuted, or maintained the defense of the action shall bear all of the costs and expenses (including reasonable attorneys’ fees) incurred in connection with the action and shall be entitled to recoup those amounts in the event of recovery, by settlement or otherwise. The amount of any recovery remaining as to any such infringement in the Licensed Territory shall be shared equally by the Parties.

(f) The Parties, including any future licensee of Lexicon in the Lexicon Territory, to the extent reasonably feasible shall collaborate to have a global, worldwide trademark to be used on the Licensed Product in the Licensed Territory and in the Lexicon Territory.
