Otsuka may inspect and conduct onsite audits of such facilities of Esperion and its Affiliates during regular business hours, and may conduct remote and onsite audits of such facilities upon reasonable advance notice to Esperion, not more than once in any [***] month period; provided, however, that Otsuka shall be entitled to conduct “for cause” audits of such facilities of Esperion and its Affiliates more frequently as and when necessary to address quality or compliance problems relating to Bulk Tablets or API(s) Manufactured by Esperion or its Affiliates for the Otsuka Territory (including to address any notice from a Governmental Authority of noncompliance with applicable Laws if such noncompliance relates to or may affect such Manufacture for the Otsuka Territory, or issuance by the FDA of a Form 483 or Warning Letter or a comparable notice issued by any other Governmental Authority), as well as in preparation for submission of Regulatory Documentation in the Otsuka Territory and in response to Regulatory Authority requirements in the Otsuka Territory.

5.7.2By Governmental Authority. If any Governmental Authority carries

-28-

out or gives notice of its intention to carry out any inspection or audit of Esperion or any of its Affiliates or CMOs or other Third Party Manufacturers in relation to Manufacture of Bulk Tablets or API(s) for the Otsuka Territory, Esperion shall promptly notify Otsuka thereof and (a) if such inspection or audit is of Esperion or its Affiliates, Esperion shall use reasonable efforts to ensure that Otsuka will have the right to be present at such inspection or audit to the extent related to Esperion’s or its Affiliates’ Manufacture of Bulk Tablets or API(s) for the Otsuka Territory, and (b) if such inspection or audit is of Esperion’s CMOs or other Third Party Manufacturers, Esperion shall, to the extent permitted by its contractual agreement with the applicable CMO or Third Party Manufacturer, permit Otsuka to observe any such inspection or audit to the extent related to the Manufacture of Bulk Tablets or API(s) for the Otsuka Territory. Following receipt of the inspection results or audit observations of the Governmental Authority from such inspection or audit (a redacted copy of which Esperion will promptly provide to Otsuka to the extent it relates to the Bulk Tablets or API(s) Manufactured for the Otsuka Territory), Esperion will prepare any appropriate responses. A copy of the responses will be provided to Otsuka for review and comment on such responses in advance of the date such responses are due, to the extent such responses pertain to the Manufacture of Bulk Tablets or API(s) for the Otsuka Territory, and Esperion shall consider Otsuka’s comments in good faith prior to responding. With respect to any dispute between the Parties related to such responses, Esperion shall have the final say. For inspections at Esperion’s CMOs and other Third-Party Manufacturers, Esperion shall provide to Otsuka a summary of any inspections and related findings that specifically pertain to the Manufacture of Bulk Tablets or API(s) for the Otsuka Territory to Otsuka. Such information shall be redacted with respect to any CMO or Third Party Manufacturer confidential or proprietary information.

-41-

Exclusivity for such Licensed Product in the Otsuka Territory and (c) the [***] anniversary of the First Commercial Sale of such Licensed Product in the Otsuka Territory (each such period, a “Royalty Term”).

During this [***]-day notice period, Otsuka shall refrain from making such payment until Esperion instructs Otsuka that (a) Esperion intends to take actions (satisfactory to both Parties) that shall obviate the need for such withholding, in which case Otsuka shall make such payment only after it is instructed to do so by Esperion, or (b) Otsuka should make such payment and withhold the required amount and pay it to the appropriate Governmental Authority and Otsuka shall promptly provide Esperion with copies of receipts or other evidence reasonably required and sufficient to allow Esperion to document such tax withholdings adequately for purposes of claiming foreign tax credits and similar benefits, the Parties shall cooperate reasonably in completing and filing documents required under the provisions of any applicable tax laws or under any other applicable Law, in connection with the making of any required tax payment or withholding payment, or in connection with any claim to a refund of or credit for any such payment, and the Parties shall cooperate to minimize such taxes in accordance with applicable Laws, including using reasonable efforts to access the benefits of any applicable treaties.

NEITHER PARTY HERETO SHALL BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THE AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT AS A RESULT OF A PARTY’S WILLFUL MISCONDUCT OR A BREACH OF SECTION 7 (CONFIDENTIALITY AND PUBLICATION), SECTION 10.4 (EXCLUSIVITY) OR THE EXCLUSIVITY TERMS OF THE LICENSES GRANTED IN SECTION 8 (LICENSES). NOTHING IN THIS SECTION 11.4 (LIMITATION OF LIABILITY) IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY.

11.5Insurance. Each Party shall, at its own expense, maintain general commercial liability insurance, including products liability insurance, contractual liability, bodily injury, property damage and personal injury coverage adequate to cover its obligations and liabilities under this Agreement and the Supply Agreement, and which are consistent with normal business practices of comparable companies with respect to similar obligations and liabilities. Such coverage shall be purchased for a minimum limit of [***] for any one (1) claim or all damages combined. The Parties shall maintain such insurance for so long as this Agreement or the Supply Agreement is in effect, and shall from time to time provide copies of certificates evidencing such insurance to each other upon request. If the insurance policy is written on a claims-made basis, then the coverage must be kept in place for at least [***] years after the termination of this Agreement.

INTELLECTUAL PROPERTY OWNERSHIP, PROTECTION AND RELATED MATTERS

12.1Inventorship; Ownership.

12.1.1Inventorship. Inventorship for inventions made during the course of the performance of this Agreement shall be determined in accordance with applicable patent Laws for determining inventorship.

12.1.2Ownership. Esperion shall own the entire right, title and interest in and to all inventions it solely Invents (i.e., solely by one or more employees of Esperion or its Affiliates (or a Third Party acting on any of their behalf)) during the Term. Otsuka shall own the entire right, title and interest in and to all inventions it solely Invents (i.e., by one or more employees of Otsuka

-49-

or its Affiliates that are Sublicensees (or a Third Party acting on any of their behalf)) during the Term. The Parties shall jointly own the entire right, title and interest in and to all inventions they Invent jointly (i.e., by one or more employees of Esperion or its Affiliates (or a Third Party acting on any of their behalf) and one or more employees of Otsuka or its Affiliates that are Sublicensees (or a Third Party acting on any of their behalf)) during the Term.

12.1.3Employee Assignment. Each Party shall ensure that all of its employees and all employees of its Affiliates that are Sublicensees who are acting under its or such Affiliates’ authority in the performance of this Agreement assign to such Party under a binding written agreement all Know-How and Patent Rights discovered, made, conceived by such employee as a result of such employee’s employment. In the case of all Third Parties acting in the performance a Party’s obligations under this Agreement, such as consultants, subcontractors, licensees, Third Party Sublicensees, outside contractors, clinical investigators, agents, or non-employees working for non-profit academic institutions, the Party that engages such Third Party shall ensure that such Third Party is also so obligated under such an agreement, unless otherwise approved by the Parties.

12.1.4Right to Practice Joint Technology. Subject to the rights, licenses (including the licenses granted to Otsuka under Section 8.1) and obligations (including royalty obligations) of the Parties hereunder, both Parties are entitled to practice Joint Technology for all purposes on a worldwide basis and license Joint Technology without consent of and without a duty of accounting to the other Party. For the avoidance of doubt, Esperion shall have no right to grant any rights or licenses under Joint Technology that would conflict with the exclusive licenses to Otsuka in the Field in the Otsuka Territory. Each Party will grant and hereby does grant all permissions, consents and waivers with respect to, and all licenses under, the Joint Technology, throughout the world, necessary to provide the other Party with such rights of use and exploitation of the Joint Technology, and will execute documents as necessary to accomplish the foregoing.

12.2Prosecution and Maintenance of Patent Rights.

12.2.1Prosecution of Esperion Patent Rights and Joint Patent Rights.

(a)Esperion has the sole responsibility to, at Esperion’s discretion, file, prosecute, and maintain (including the defense of any interference or opposition proceedings or inter partes review and any equivalent proceedings in the Territory), all Esperion Patent Rights and Joint Patent Rights.

(b)Esperion shall furnish to Otsuka, via electronic mail or such other method as mutually agreed by the Parties, copies of documents received from outside counsel in the course of filing, prosecution or maintenance of or copies of documents filed with the relevant national patent offices with respect to the filing, prosecution, and maintenance of all Esperion Patent Rights and Joint Patent Rights in the Otsuka Territory within a reasonable time after the receipt or filing of such documents. Esperion shall provide Otsuka and its patent counsel with a reasonable opportunity to consult with and provide comments to Esperion and its patent counsel regarding the filing and contents of any such application, amendment, submission or response. All timely advice and suggestions of Otsuka and its patent counsel shall be taken into consideration in good faith by Esperion and its patent counsel in connection with such filing.

-50-

(c)Esperion shall not, without the prior written consent of Otsuka, abandon, forfeit or otherwise cease the prosecution or maintenance of any of the Existing Esperion Patent Rights in the Otsuka Territory; provided that, Otsuka’s consent shall not be unreasonably withheld, conditioned or delayed if Esperion has, and informs Otsuka of, a reasonable strategic reason for ceasing the prosecution and maintenance of an Existing Esperion Patent Right in the Otsuka Territory. In the event that Otsuka provides consent pursuant to the preceding sentence with respect to any Existing Esperion Patent Right or Esperion elects not to maintain patent protection on any other Esperion Patent Rights or on any Joint Patent Rights in the Otsuka Territory, Esperion shall notify Otsuka at least [***] days before any such Patent Rights would become abandoned or otherwise forfeited. Otsuka may, upon written notice to Esperion, elect to assume prosecution and maintenance of such Esperion Patent Rights or Joint Patent Rights in the Otsuka Territory and, in that event, Esperion shall assign all of its right, title and interest in and to such Esperion Patent Rights or Joint Patent Rights to Otsuka at Otsuka’s sole cost and expense, and such Esperion Patent Rights or Joint Patent Rights shall become Otsuka Patent Rights; provided that, if such assignment is not possible, then Otsuka shall have the right (but not the obligation), at its sole cost and expense, to prosecute and maintain in the Otsuka Territory patent protection on such Esperion Patent Rights or Joint Patent Right in the name of Esperion.

(d)Esperion shall bear all costs incurred in connection with the filing, prosecution and maintenance (including the defense of any interference or opposition proceedings or inter partes review and any equivalent proceedings) of the Esperion Patent Rights and Joint Patent Rights in the Otsuka Territory and in the Esperion Territory, except to the extent Otsuka will bear such costs in accordance with Section 12.2.1(c).

12.2.2Prosecution of Otsuka Patent Rights.

(a)Otsuka has the sole responsibility to, at Otsuka’s discretion, file, prosecute, and maintain (including the defense of any interference or opposition proceedings or inter partes review and any equivalent proceedings), all Otsuka Patent Rights. Otsuka will use good faith efforts to segregate into separate Patent Rights claims of Otsuka Patent Rights that solely relate to Bempedoic Acid, or any product comprising or containing Bempedoic Acid, from claims that relate to other subject matter, to the extent such segregation is feasible under applicable patent rules and regulations. Any such separate Otsuka Patent Rights that contain claims solely relating to Bempedoic Acid, or a product comprising or containing Bempedoic Acid, and no other subject matter shall be referred to herein as “Otsuka BA Patent Rights.”

(b)With respect to Otsuka Patent Rights that are Otsuka BA Patent Rights or that contain both claims related to Bempedoic Acid, or any product comprising or containing Bempedoic Acid, and claims related to other subject matter, Otsuka shall furnish to Esperion, via electronic mail or such other method as mutually agreed by the Parties, copies of documents received from outside counsel in the course of filing, prosecution or maintenance of or copies of documents filed with the relevant national patent offices with respect to the filing, prosecution, and maintenance of such Otsuka Patent Rights within a reasonable time after the receipt or filing of such documents. Otsuka shall provide Esperion and its patent counsel with a reasonable opportunity to consult with and provide comments to Otsuka and its patent counsel

-51-

regarding the filing and contents of any such application, amendment, submission or response. All timely advice and suggestions of Esperion and its patent counsel shall be taken into consideration in good faith by Otsuka and its patent counsel in connection with such filing.

(c)In the event that Otsuka is able to segregate claims and file separate Otsuka BA Patent Rights and in the event Otsuka elects not to maintain patent protection on any such Otsuka BA Patent Rights in any country(ies), Otsuka shall notify Esperion at least [***] days before any such Otsuka BA Patent Rights would become abandoned or otherwise forfeited. Esperion may, upon written notice to Otsuka, elect to assume prosecution and maintenance of such Otsuka BA Patent Rights in such country(ies) and, in that event, Otsuka shall assign all of its right, title and interest in and to such Otsuka BA Patent Rights to Esperion at Esperion’s sole cost and expense, and such Otsuka BA Patent Rights shall become Esperion Patent Rights; provided that, if such assignment is not possible, then Esperion shall have the right (but not the obligation), at its sole cost and expense, to prosecute and maintain in such country(ies) patent protection on such Otsuka BA Patent Rights in the name of Otsuka. Notwithstanding the foregoing, Otsuka shall be entitled to abandon, forfeit or otherwise elect not to maintain patent protection on any Otsuka BA Patent Right in any country(ies) for reasonable strategic reasons provided that Otsuka also abandons or forfeits any other Patent Rights in such country(ies) that contain the same specification as such Otsuka BA Patent Right.

(d)In the event Otsuka is unable to segregate claims and file separate Otsuka BA Patent Rights, and in the event Otsuka elects not to maintain patent protection in any country(ies) on any Otsuka Patent Rights that contain both claims related to Bempedoic Acid, or any product comprising or containing Bempedoic Acid, and claims related to other subject matter, Otsuka shall notify Esperion at least [***] days before any such Otsuka Patent Rights would become abandoned or otherwise forfeited. Esperion may, upon written notice to Otsuka, assume prosecution and maintenance of such Otsuka Patent Rights in such country(ies) and, in that event, Otsuka shall assign all of its right, title and interest in and to such Otsuka Patent Rights to Esperion at Esperion’s sole cost and expense, and such Otsuka Patent Rights shall become Esperion Patent Rights; provided that, if such assignment is not possible, then Esperion shall have the right (but not the obligation), at its sole cost and expense, to prosecute and maintain in such country(ies) patent protection on such Otsuka Patent Rights in the name of Otsuka. With respect to any Otsuka Patent Right that is assigned to Esperion and becomes an Esperion Patent Right pursuant to this Section 12.2.2(d), Esperion shall, and hereby does, grant to Otsuka and its Affiliates, effective as of the date of such assignment without any further action required on the part of either Party, a non-exclusive, royalty-free, fully paid-up, irrevocable and perpetual license, with the right to grant sublicenses through multiple tiers, under such Esperion Patent Right (formerly Otsuka Patent Right) solely to research, develop, make, have made, use, sell, have sold, offer to sell, import and otherwise exploit any products other than products comprising or containing Bempedoic Acid. Notwithstanding the foregoing, Otsuka shall be entitled to abandon, forfeit or otherwise elect not to maintain patent protection on any Otsuka Patent Right that contains both claims related to Bempedoic Acid, or any product comprising or containing Bempedoic Acid, and claims related to other subject matter for reasonable strategic reasons.

-52-

(e)Otsuka shall bear all costs incurred in connection with the filing, prosecution and maintenance (including the defense of any interference or opposition proceedings or inter partes review and any equivalent proceedings) of the Otsuka Patent Rights in the Otsuka Territory and in the Esperion Territory, except to the extent Esperion will bear such costs in accordance with Section 12.2.2(c) or Section 12.2.2(d).

12.3Third Party Infringement.

12.3.1Notice of Infringement. During the Term, each Party will promptly notify the other Party in writing of any known or suspected infringement or unauthorized use or misappropriation by a Third Party of Otsuka Technology, Esperion Technology, or Joint Technology concerning any product intended for use in preventing, diagnosing or treating any disease or condition in humans (including development, Manufacture, or Commercialization) (such infringement or unauthorized use or misappropriation, “Competing Infringement”) of which such Party becomes aware. The notifying Party will provide the other Party with all evidence available to it supporting its belief that there is Competing Infringement.

12.3.2Right to Enforce.

(a)Subject to the provisions of any Esperion Third Party Agreement, Otsuka shall have the first right, but not the obligation, to take any reasonable measures it deems appropriate with respect to any Competing Infringement in the Otsuka Territory under any Otsuka Technology, Esperion Technology or Joint Technology. Such measures may include (a) initiating or prosecuting an infringement, misappropriation or other appropriate suit or action (each an “Infringement Action”) in the Otsuka Territory, or (b) subject to Section 8.1.2 (Otsuka Sublicense Rights), granting adequate rights and licenses to any Third Party necessary to render continued Competing Infringement in the Otsuka Territory non-infringing. Notwithstanding the foregoing, if Otsuka does not inform Esperion that it intends to either initiate such an Infringement Action or grant adequate rights and licenses to such Third Party within [***] days after Otsuka’s receipt of a notice of infringement pursuant to Section 12.3.1 (Notice of Infringement) and does not provide Esperion commercially reasonable reasons why Otsuka does not intend to initiate such Infringement Action or grant such rights or licenses within such [***]-day period, then Esperion will have the second right, but not the obligation, to initiate such Infringement Action, but solely with respect to any Esperion Technology or Joint Technology.

(b)Esperion shall have the first right, but not the obligation, to take any reasonable measures it deems appropriate with respect to any Competing Infringement in the Esperion Territory under any Otsuka BA Technology, Esperion Technology or Joint Technology. Such measures may include (a) initiating or prosecuting an Infringement Action, or (b) granting adequate rights and licenses to any Third Party necessary to render continued Competing Infringement in the Esperion Territory non-infringing. Notwithstanding the foregoing, if Esperion does not inform Otsuka that it intends to either initiate such an Infringement Action or grant adequate rights and licenses to such Third Party within [***] days after Esperion’s receipt of a notice of infringement pursuant to Section 12.3.1 (Notice of Infringement) and does not provide Otsuka commercially reasonable reasons why Esperion does not intend to initiate such

-53-

Infringement Action or grant such rights or licenses within such [***]-day period, then Otsuka will have the second right, but not the obligation, to initiate such Infringement Action, but solely with respect to any Otsuka BA Technology. For clarity, with respect to Otsuka Patent Rights, Esperion shall only have the right under this Section 12.3.2(b) to enforce Otsuka BA Patent Rights against any Competing Infringement in the Esperion Territory and Esperion shall not have the right to enforce any other Otsuka Patent Rights against Competing Infringement in the Esperion Territory.

12.3.3Control; Cooperation. The Party initiating any Infringement Action (such Party, the “Responsible Party”) shall have the right to control the initiation and prosecution of any Infringement Action, including the right to select counsel therefor, at its own expense. If requested by the Responsible Party, the other Party shall join as a party to such Infringement Action and will execute and cause its Affiliates to execute all documents, including registration of exclusive license, necessary for the Responsible Party to initiate, prosecute, maintain or defend such action or proceeding. In addition, at the Responsible Party’s request, the other Party shall provide reasonable assistance to the Responsible Party in connection with an Infringement Action at no charge to the Responsible Party except for reimbursement by the Responsible Party of reasonable Out-of-Pocket Costs incurred in rendering such assistance.

12.3.4Sharing of Recoveries. Any amounts recovered by either Party pursuant to this Section 12.3 (Third Party Infringement) will be used first to reimburse the Parties for their reasonable costs and expenses, including attorneys’ fees incurred in making such recovery (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses) with any remainder [***].

12.4Third Party Claims.

12.4.1Third Party Infringement Suit. If a Third Party sues a Party (the “Sued Party”) alleging that the Sued Party’s, or the Sued Party’s Sublicensee’s, Development, Manufacture or Commercialization of the Licensed Product in the Otsuka Territory infringes or will infringe said Third Party’s intellectual property (“Third Party Infringement Suit”), then upon the Sued Party’s request and in connection with the Sued Party’s defense of any such Third Party Infringement Suit, the other Party will provide reasonable assistance to the Sued Party for such defense. 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 enter into any settlement of any Third Party Infringement Suit that is instituted or threatened to be instituted against the other Party without the other Party’s prior written consent, which will not be unreasonably withheld, conditioned or delayed; except that, such consent will not be required if such settlement includes a release of all liability in favor of the other Party. Further, the Sued Party shall not settle or compromise any Third Party Infringement Suit, or knowingly take any other action in the course thereof, in a manner that materially adversely affects the other Party’s rights or interests, without the written consent of such other Party. Any monetary damages that are required to be paid by the Sued Party to a Third Party with respect to the Otsuka Territory pursuant to a judgment rendered in a Third Party Infringement Suit will be borne by the Parties equally.

-54-

12.4.2Esperion Third Party Agreements. Esperion shall remain responsible for the payment of all royalties, license fees, milestone payments and other payment obligations under all agreements, including all Esperion Third Party Agreements, entered into by Esperion prior to the Effective Date. On a Licensed Product-by-Licensed Product basis, in the event that Esperion reasonably determines that it is necessary or useful to acquire rights under a Third Party’s Patent Rights, Know-How or other intellectual property, through a license, acquisition or other agreement with such Third Party, for the Development, Manufacture or Commercialization of such Licensed Product in both the Otsuka Territory and the Esperion Territory, or if Otsuka and Esperion agree that Esperion, rather than Otsuka, will acquire rights under a Third Party’s Patent Rights, Know-How or other intellectual property, through a license, acquisition or other agreement with such Third Party, for the Development, Manufacture or Commercialization of such Licensed Product in the Otsuka Territory only (any such agreement, a “Third Party IP Agreement”), Esperion shall ensure that such Third Party IP Agreement shall include the right to grant a sublicense to Otsuka in the Otsuka Territory in order for Otsuka to exercise its rights and licenses hereunder and Esperion shall negotiate such Third Party IP Agreement on commercially reasonable terms that shall not favor or burden one Party’s Territory over the other. In the event Esperion enters into such a Third Party IP Agreement, Otsuka shall bear [***] of royalty payments due thereunder that are attributable to Net Sales of Licensed Products in the Otsuka Territory and [***] of any milestone payments thereunder that are specific to the Otsuka Territory, and Esperion shall bear all other payments under such Third Party IP Agreement. Esperion shall send Otsuka an invoice for its share of such Otsuka Territory-specific royalty payments and milestone payments, and Otsuka shall pay such payments within [***] days of the receipt of such invoice.

12.5Common Interest. All information exchanged between the Parties’ representatives pursuant to this Section 12 (Intellectual Property Ownership, Protection and Related Matters) regarding the preparation, filing, prosecution, maintenance, or enforcement of Patent Rights will be deemed Confidential Information. In addition, the Parties acknowledge and agree that, with regard to such preparation, filing, prosecution, maintenance, and enforcement of the Esperion Patent Rights and Joint Patent Rights the interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning such Patent Rights, including privilege under the common interest doctrine and similar or related doctrines.

12.6Patent Term Extensions.

12.6.1Esperion Patent Rights. Subject to the provisions of any Esperion Third Party Agreement, Esperion shall use Commercially Reasonable Efforts to obtain all available extensions of Esperion Patent Rights and Joint Patent Rights in the Otsuka Territory, as requested by Otsuka, provided that Otsuka shall reimburse Esperion all Out-of-Pocket costs incurred by Esperion in connection with seeking and obtaining such extensions.

12.6.2Otsuka Patent Rights. Otsuka shall use Commercially Reasonable Efforts to obtain all available extensions of Otsuka Patent Rights that are Otsuka BA Patent Rights or that contain both claims related to Bempedoic Acid, or any product comprising or containing

-55-

Bempedoic Acid, and claims related to other subject matter in the Esperion Territory, as requested by Esperion, provided that Esperion shall reimburse Otsuka all Out-of-Pocket costs incurred by Otsuka in connection with seeking and obtaining such extensions.

12.7Prosecution and Enforcement of Product Trademarks; General.

12.7.1Prosecution of Product Trademarks; General. Esperion shall own all rights, title and interest in and to all Product Trademarks. Esperion shall have the sole responsibility to file, prosecute, register and maintain (including the defense of opposition proceedings and any equivalent proceedings) all Product Trademarks, including Esperion Trademarks and back-up Trademarks for the Licensed Products (including any logo associated therewith), which shall not be confusingly similar to any Otsuka mark, on a timely manner in the Otsuka Territory throughout the Term. Consistent with Otsuka’s exclusive right to Product Trademarks under Section 8.1.1 (Exclusive License Grant), Otsuka shall use Product Trademarks in a manner consistent with this Agreement, including the Global Branding Strategy, and for no other purpose. Otsuka shall use any Product Trademarks in a manner consistent with trademark usage guidelines provided by Esperion from time-to-time. Subject to the foregoing: (a) Otsuka shall not use any other marks that are confusingly similar to any Product Trademark, (b) all rights in each of the Product Trademarks shall remain at all times the sole property of Esperion, and all use of such Product Trademarks shall inure to the benefit of Esperion, and (c) Otsuka agrees not to contest or attack Esperion’s ownership of the Product Trademarks. Otsuka shall reimburse Esperion for its reasonable Out-of-Pocket Cost incurred in connection with the filing, prosecution, registration and maintenance (including the defense of opposition proceeding and equivalent proceeding) of the Product Trademarks in the Otsuka Territory. Esperion shall invoice Otsuka from time to time for such Out-of-Pocket Costs, and Otsuka shall pay Esperion within [***] days of receipt of such invoice.

12.7.2Enforcement of Product Trademarks. During the Term, each Party will promptly notify the other Party in writing of any known or suspected infringement or unauthorized use or misappropriation by a Third Party of any Product Trademarks in the Otsuka Territory. Otsuka shall have the right, but not the obligation, to take any reasonable measures it deems appropriate, at its sole cost and expense, including initiating or prosecuting an infringement, misappropriation or other appropriate suit or action to enforce the Product Trademarks in the Otsuka Territory (“Product Trademark Infringement Action”). Otsuka shall have the right to control the initiation and prosecution of any Product Trademark Infringement Action, including the right to select counsel therefor, at its own expense. If requested by Otsuka, Esperion shall join as a party to such Product Trademark Infringement Action and will execute and cause its Affiliates to execute all documents necessary for Otsuka to initiate, prosecute, maintain or defend such action or proceeding. In addition, at Otsuka’s request, Esperion shall provide reasonable assistance to Otsuka in connection with a Product Trademark Infringement Action at no charge to Otsuka except for reimbursement by Otsuka of reasonable Out-of-Pocket Costs incurred by Esperion in rendering such assistance.

TERM AND TERMINATION; REMEDIES

13.1Term. The Agreement shall be effective as of the Effective Date and, unless terminated earlier pursuant to Section 13.2 (Termination Rights), this Agreement shall continue in effect, on a Licensed Product-by-Licensed Product basis until the expiration of the Royalty Term for such Licensed Product (“Term”). Upon the expiration of the Term with respect to a Licensed Product (without this Agreement being terminated earlier pursuant to Section 13.2 (Termination Rights)), Otsuka’s rights to such Licensed Product (and all corresponding Authorized Generic Products) and all license grants to Otsuka hereunder with respect to such Licensed Product (and all corresponding Authorized Generic Products) shall continue, shall remain exclusive to Otsuka (even as to Esperion) and shall become fully paid-up, royalty-free, perpetual and irrevocable. Prior to expiration of the Term with respect to a Licensed Product (without this Agreement being terminated earlier pursuant to Section 13.2 (Termination Rights)), upon Otsuka’s written request, the Parties shall discuss a schedule for assignment to Otsuka of Esperion’s contracts with CMOs that relate to the Manufacture or supply of the API(s) and/or Bulk Tablets (if the technology transfer has not occurred under Section 5.4 (Technology Transfer)) for the Otsuka Territory, and Esperion shall implement such assignments in accordance with such schedule in order for the assignment of such contracts to be effective at the expiration of the Term with respect to such Licensed Product. Esperion shall use Commercially Reasonable Efforts to support such assignments and shall bear its internal costs to implement the assignments. Otsuka will bear its internal costs and all external expenses, including Esperion’s Out-of-Pocket Costs, if any, to implement such assignments.

13.2Termination Rights. This Agreement may not be terminated by either Party except as provided in this Section 13.2 (Termination Rights).

13.2.1Termination of Agreement for Convenience. Otsuka shall have the right to terminate this Agreement in its entirety at any time after the earlier of: [***]. Notwithstanding the foregoing, Otsuka shall have the right to terminate this Agreement in its entirety at any time with respect to a Licensed Product: (i) due to Safety Reasons; or (ii) withdrawal of Regulatory Approval for such Licensed Product outside the Otsuka Territory.

13.2.2Termination of Agreement in its Entirety for Cause. This Agreement may be terminated in its entirety at any time during the Term upon written notice by either Party if the other Party is in material breach of its obligations hereunder and has not cured such breach within [***] days in the case of a payment breach, or within [***] days in the case of all other breaches, after notice requesting cure of the breach; provided, however, that if any breach other than a payment breach is not reasonably curable within [***] days and if a Party is making a bona fide effort to cure such breach, such termination shall be delayed for a time period to be agreed by both Parties, not to exceed an additional [***] days, in order to permit such Party a reasonable period of time to cure such breach. Notwithstanding the foregoing, if the allegedly breaching Party disputes in good faith the existence, materiality, or failure to cure of any breach, and provides written notice to the other Party of such dispute within the relevant cure period, the other Party will not have the right to terminate this Agreement in accordance with this Section 13.2.2 unless and until the relevant dispute has been resolved pursuant to Section 14.4. During the pendency of

-57-

such dispute, the applicable cure period will be tolled, all the terms of this Agreement will remain in effect, and the Parties will continue to perform all of their respective obligations hereunder.

13.2.3Challenges of Patent Rights. If, during the Term, Otsuka (a) commences or participates in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise asserts any claim, challenging or denying the validity or enforceability of any claim of any Esperion Patent Rights or (b) actively assists any other Person in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim of such Esperion Patent Rights (each of (a) and (b), a “Patent Challenge”), then, to the extent permitted by the applicable Laws, Esperion shall have the right, exercisable within [***] days following receipt of notice regarding such Patent Challenge, in its sole discretion, to give notice to Otsuka that Esperion may terminate the license(s) granted under such Esperion Patent Right(s) to Otsuka pursuant to this Agreement [***] days following such notice (or such longer period as Esperion may designate in such notice), and, unless Otsuka withdraws or causes to be withdrawn all such challenge(s) (or in the case of ex-parte proceedings, multi-party proceedings, or other Patent Challenges that Otsuka does not have the power to unilaterally withdraw or cause to be withdrawn, Otsuka ceases actively assisting any other party to such Patent Challenge and, to the extent Otsuka is a party to such Patent Challenge, it withdraws from such Patent Challenge) within such [***]-day period, Esperion shall have the right to terminate the license(s) granted under such Esperion Patent Right(s) to Otsuka pursuant to this Agreement by providing written notice thereof to Otsuka. Notwithstanding the foregoing, Esperion shall not have a right to terminate any license(s) pursuant to this Section 13.2.3 (Challenges of Patent Rights) with respect to any Patent Challenge that is made in response to and defense of any claim or action that Esperion first asserts against Otsuka or any of its Affiliates or Sublicensees.

13.2.4Bankruptcy. In the event that the performance of the respective obligations of this Agreement become untenable as a result of a Party filing a petition of bankruptcy, enters into insolvency or liquidation proceedings either voluntarily or involuntarily, or if a receiver is appointed with respect to the assets of such Party, or any similar action is filed under applicable Laws, and such measure is not dismissed within [***] days, to the extent permitted by the applicable Laws of such Party’s Territory, the other Party may terminate this Agreement by written notice to such Party. Notwithstanding the foregoing, the Parties acknowledge that a Party to this Agreement may, from time-to-time, make changes in its corporate structure, including inter alia changes in the shareholdings of Affiliates, which would not constitute a case of bankruptcy under this Section 13.2.4 (Bankruptcy).

13.3Effect of Termination.

13.3.1Consequences of Termination or Expiration of this Agreement. If this Agreement expires or is terminated by a Party prior to its expiration, in each case, in its entirety at any time and for any reason, then the following terms will apply as specified below:

(a)Licenses. Upon termination of this Agreement under Section 13.2 prior to expiration (for clarity, not if this Agreement expires pursuant to Section 13.1), the licenses

-58-

granted by Esperion to Otsuka under this Agreement will terminate and Otsuka and its Sublicensees will cease selling Licensed Products.

(b)Return of Information and Materials. Upon termination or expiration, the Parties will return (or destroy, as directed by the other Party) all data, files, records, and other materials containing or comprising the other Party’s Confidential Information. Notwithstanding the foregoing, the Parties will be permitted to retain one copy of such data, files, records, and other materials for archival and legal compliance purposes, and the Parties will not be required to destroy Confidential Information that is stored automatically, such as through server backup processes.

(c)Accrued Rights. Termination of this Agreement for any reason will be without prejudice to any rights or financial compensation that will have accrued to the benefit of a Party prior to such termination. Such termination will not relieve a Party from obligations that are expressly indicated to survive the termination of this Agreement.

13.4Special Consequences of Certain Terminations. If Esperion terminates this Agreement under Section 13.2 for any reason, or Otsuka terminates this Agreement under Section 13.2, other than under Section 13.2.2 (Termination of Agreement in its Entirety for Cause) or Section 13.2.4 (Bankruptcy), (for clarity, not if this Agreement expires pursuant to Section 13.1 or if Otsuka terminates this Agreement under Section 13.2.2 (Termination of Agreement in its Entirety for Cause) or Section 13.2.4 (Bankruptcy)), then, in addition to the terms set forth in Section 13.3.1 (Consequences of Termination or Expiration of this Agreement), the following additional terms will also apply:

13.4.1License Grant. The license granted by Otsuka to Esperion under Section 8.2 (License Grants to Esperion) shall automatically become irrevocable, perpetual and worldwide.

13.4.2Disclosure of Certain Commercialization Related Information. Otsuka will disclose to Esperion for use with respect to the further Commercialization of the Licensed Product, material information pertaining to pricing and market access strategy and health

-59-

economic study information, in each case for the Licensed Product in the Otsuka Territory in the possession of Otsuka as of the date of such reversion that relate to such Licensed Products that is necessary for the continued Commercialization of such Licensed Products in the Otsuka Territory.

13.4.3Regulatory Materials. Within [***] days following the date of the termination, Otsuka will assign, and hereby does assign, to Esperion all of Otsuka’s right, title and interest in and to all Regulatory Documentation for the Licensed Products, including any Regulatory Approvals and NHI Price Listing that relate to the applicable Licensed Product.

13.4.4Stock of API(s) and Finished Drug Product. Otsuka will have the right to continue to sell and otherwise Commercialize all of the inventory of finished drug product for such Licensed Product held by Otsuka as of the effective date of termination and Otsuka shall continue to pay to Esperion any applicable royalties due on any such sales. The disposition, including buy-back by Esperion, of any inventory of API(s) held by Otsuka as of the effective date of termination will be governed by the Supply Agreement.

13.4.5Transition Activities.

(a)The Parties wish to provide a mechanism to ensure that, assuming the Licensed Product is available to patients as of the reversion date, patients who were being treated with the Licensed Product prior to such termination or who desire access to the Licensed Product can continue to have access to such Licensed Product while the regulatory and commercial responsibilities for the Licensed Product are transitioned from Otsuka to Esperion. As such, Esperion may request Otsuka to perform transition activities that are necessary or useful to (1) transition Otsuka’s Commercialization activities (if any) to Esperion to minimize disruption to sales, (2) provide patients with continued access to the applicable Licensed Products (if applicable), (3) enable Esperion (or Esperion’s designee) to assume and execute the responsibilities under all Regulatory Approvals and ongoing Clinical Studies for the applicable Licensed Product, and (4) ensure long-term continuity of supply for the Licensed Product (collectively, the “Transition Activities”), but no longer than [***] years following the effective date of termination.

(b)Esperion may elect to have Otsuka perform the applicable Transition Activities by providing written notice to Otsuka no later than [***] days following the effective date of the termination. If Esperion requests Transition Activities, the Parties will mutually agree upon a transition plan for Otsuka to perform the applicable Transition Activities including delivery and transition dates. In addition, the Parties will establish a transition committee consisting of at least each Party’s Alliance Managers, and up to [***] additional representatives from each Party who are from other relevant functional groups to facilitate a smooth transition. While Otsuka is providing applicable Transition Activities, Otsuka and Esperion will agree on talking points and a communication plan to customers, specialty pharmacies, physicians, regulatory authorities, patient advocacy groups, and clinical study investigators, in each case only if applicable at the time of reversion, and Otsuka will make all such communications to such applicable entities in accordance with the mutually agreed talking points.

-60-

(c)Esperion will pay Otsuka’s internal costs to perform the Transition Activities, calculated using the same methodology as Otsuka used to calculate such expenses for such Licensed Product in its most recently audited financial statements prior to the termination date. In addition, Esperion will reimburse Otsuka’s Out-of-Pocket Costs to perform the Transition Activities. Except as set forth in Section 13.4.4, Esperion will own all revenue derived from the Licensed Product after the termination date and Otsuka will remit all such revenues to Esperion no later than the [***] day following the end of the month in which such revenue was received.

Esperion Press Release:

Esperion Announces Agreement with Otsuka Pharmaceutical Co., Ltd. for Development and Commercialization of NEXLETOL™ (bempedoic acid) and NEXLIZET™ (bempedoic acid and ezetimibe) Tablets in Japan

– Esperion to Receive $60 Million Upfront Payment –

–Up to $510 Million in Total Milestones –

– Substantial Tiered Royalties –

– Combines Esperion’s Expertise in Lipid Management with Otsuka’s Deep Cardiovascular Drug Development and Commercialization Expertise in Japan –

ANN ARBOR, Mich., Apr. 20, 2020 (GLOBE NEWSWIRE) -- Esperion (NASDAQ: ESPR) today announced that they have entered into a collaboration agreement with Otsuka Pharmaceutical Co., Ltd. for the development and commercialization of NEXLETOL and NEXLIZET tablets in Japan. Both medicines were recently approved in both the US and EU.

The collaboration advances the commitment of both companies to provide cost-effective, oral, once-daily, non-statin LDL-cholesterol (LDL-C) lowering medicines for hypercholesterolemia patients in Japan. This development and commercialization collaboration combines Esperion’s expertise in lipid management with Otsuka’s deep cardiovascular drug development and commercialization expertise in Japan.

Under the terms of the agreement, Esperion will grant Otsuka exclusive rights to NEXLETOL and NEXLIZET tablet development and commercialization in Japan. Otsuka will be responsible for all development, regulatory, and commercialization activities in Japan. In addition, Otsuka will fund all Japan-specific development costs associated with the program. Esperion estimates this amount to total up to $100 million over the next few years. Esperion will receive an upfront cash payment of $60 million as well as up to an additional $450 million in total development and sales milestones. Esperion will also receive tiered royalties from 15 percent to 30 percent on net sales in Japan.

“We are thrilled to partner with Otsuka, one of the leading pharmaceutical companies in Japan. Otsuka shares our vision of the potential for convenient oral, once-daily, non-statin LDL-C lowering medicines to help hypercholesterolemia patients in Japan,” said Tim Mayleben, president and chief executive officer of Esperion. “Otsuka’s history of successfully commercializing cardiovascular medicines in Japan, and overlapping healthcare provider targets make this a highly synergistic collaboration. This collaboration continues the evolution of Esperion to a truly global research and development driven commercial pharmaceutical company and further validates the global value of our medicines.”

Makoto Inoue, president and representative director of Otsuka Pharmaceutical commented, “We aspire to become an indispensable company for patients, physicians and others around the world. If approved

in our home market of Japan, bempedoic acid will represent another step forward in our fulfillment of that aspiration.”

Esperion Therapeutics

Through scientific and clinical excellence, and a deep understanding of cholesterol biology, the experienced Lipid Management Team at Esperion is committed to developing new LDL-C lowering medicines that will make a substantial impact on reducing global cardiovascular disease, the leading cause of death around the world. For more information, please visit www.esperion.com and follow us on Twitter at www.twitter.com/EsperionInc.

Esperion Therapeutics’ Commitment to Patients with Hyperlipidemia

High levels of LDL-C can lead to a build-up of fat and cholesterol in and on artery walls (known as atherosclerosis), potentially leading to cardiovascular events, including heart attack and stroke. In the U.S., 96 million people, or more than 37 percent of the adult population, have elevated LDL-C. There are approximately 18 million people in the U.S. living with elevated levels of LDL-C despite taking maximally tolerated lipid-modifying therapy — including individuals considered statin averse — leaving them at high risk for cardiovascular events.¹ In the United States, more than 50 percent of atherosclerotic cardiovascular disease (ASCVD) patients and heterozygous familial hypercholesterolemia (HeFH) patients who are not able to reach their guideline recommended LDL-C levels with statins alone need less than a 40 percent reduction to reach their LDL-C threshold goal.²

Esperion's mission as the Lipid Management Company is to deliver oral, once-daily medicines that complement existing oral drugs to provide the additional LDL-C lowering that these patients need.

Forward-Looking Statements

This press release contains forward-looking statements that are made pursuant to the safe harbor provisions of the federal securities laws, including statements regarding the clinical development and commercialization plans for bempedoic acid tablet and the bempedoic acid / ezetimibe fixed dose combination tablet, including Esperion's timing, designs, plans for announcement of results regarding its CLEAR Outcomes study and other ongoing clinical studies for bempedoic acid tablet and the bempedoic acid / ezetimibe combination fixed dose tablet, timing for the review and approval of expanded indications for their effect on cardiovascular events, and Esperion's expectations for the market for medicines to lower LDL-C, including the commercial launch and market adoption of bempedoic acid tablet and the bempedoic acid / ezetimibe fixed dose combination tablet in the European Union. Any express or implied statements contained in this press release that are not statements of historical fact may be deemed to be forward-looking statements. Forward-looking statements involve risks and uncertainties that could cause Esperion's actual results to differ significantly from those projected, including, without limitation, delays or failures in Esperion’s clinical development and commercialization plans, or approval of expanded indications, that existing cash resources may be used more quickly than anticipated, that Otsuka is able to successfully commercialize bempedoic acid and the bempedoic acid / ezetimibe fixed dose combination tablet, the impact of COVID-19 on our business, clinical activities and commercial development plans, and the risks detailed in Esperion's filings with the Securities and Exchange Commission. Any forward-looking statements contained in this press release speak only as of

the date hereof, and Esperion disclaims any obligation or undertaking to update or revise any forward-looking statements contained in this press release, other than to the extent required by law.

Otsuka Press Release (English Version):

Otsuka Enters into Licensing Agreement in Japan for Bempedoic Acid,
a Treatment for Hypercholesterolemia

Otsuka Pharmaceutical Co., Ltd. and Esperion Therapeutics, Inc. (headquartered in Michigan, U.S.) announce a licensing agreement in which Otsuka acquires from Esperion exclusive development and commercialization rights in Japan for bempedoic acid (chemical name).

Bempedoic acid, designed by Esperion, has a novel mechanism of action that inhibits cholesterol and fatty acid synthesis pathways by acting on ATP (adenosine triphosphate-citrate lyase, an enzyme that breaks down citric acid in the liver.

It is a once-daily, oral therapeutic agent for hypercholesterolemia that was developed for patients who cannot take statins due to side effects or whose LDL cholesterol levels do not decrease sufficiently when taking statins or other lipid-lowering therapies. Manufacturing and marketing approvals for bempedoic acid have been obtained in the U.S. and Europe.

Under the terms of the agreement, Otsuka will pay Esperion a one-time payment of USD 60 million, as well as milestones in accordance with achievement of development and sales goals. Otsuka will conduct future clinical trials in Japan and bear the costs. Otsuka will have exclusive marketing rights in Japan and will pay royalties to Esperion based on sales levels.
