(c) Neuren and its Affiliates will not, and will cause licensees, sublicensees and acquirers not to, develop or commercialize a Competing Product in the Territory during the Exclusivity Period; provided, however, that in the event Neuren (or its Affiliate, licensee, sublicensee or acquirer) acquires such Competing Product during the Exclusivity Period, it must, unless ACADIA agrees to the contrary, within […***…] of such acquisition, either divest such Competing Product to a Third Party, or discontinue the development or commercialization of such Competing Product.

(d) Furthermore, Neuren and its Affiliates will not, directly or indirectly, and by incorporating the prohibition contained in this clause 8.1(d) in any license or sublicence agreement pertaining to any IGF-1 Derivative-based Compound, will cause licensees, sublicensees and acquirers not to, administer any IGF-1 Derivative Compound to any patient diagnosed with Rett syndrome or Fragile X syndrome during the Exclusivity Period (an “IGF-1 Derivative-based Competing Product”). For the avoidance of doubt, the foregoing sentence precludes administering indirectly through a third party (e.g., a clinical research organization) or making such compound, or any product containing such compound, available to a third party (e.g., a physician or institution) for

Licence Agreement ½Page 23

*** Confidential Treatment Requested

administration to any patient diagnosed with Rett syndrome or Fragile X syndrome. For purposes of this clause 8.1(d), “IGF-1 Derivative Compound” shall mean any compound (including, without limitation, NNZ-2591) that is a derivative of insulin-like growth factor one, including all salts, esters, mixtures, hydrates, isomers, solvates, complexes, isotopalogs, polymorphs, resinates, metabolites, impurities, or degradation products of such compound, that in each case is not (a) the Compound or (b) an Improvement of the Compound.

(B) sell or fill any orders for any Compound or Product to customers outside the Field or the Territory or to any Third Party in the Territory that it has reasonable grounds to believe are intended for use or sale outside the Field or the Territory.

8.3 Non-exclusive remedy for breach of clause 8.1(d)

(a) In addition to any other rights and remedies available to ACADIA, effective as of the date of any breach of clause 8.1(d) (the “IGF-1 Derivative-based Competing Product License Date”), Neuren and its Affiliates hereby grant to ACADIA an exclusive worldwide license under all of their Intellectual Property Rights to the IGF-1 Derivative-based Competing Product that is the subject of such breach, to make, have made, use, offer for sale, sell, and import with the right to grant sublicenses, any product containing such IGF-1 Derivative-based Competing Product as an active ingredient, alone or in combination with one or more other active pharmaceutical ingredient(s), in any dosage form or formulation (“IGF-1 Derivative-based Competing Product License”).  Neuren shall provide ACADIA with prompt notice of the event giving rise to the IGF-1 Derivative-based Competing Product License Date, and as promptly as practicable thereafter, the parties shall document the IGF-1 Derivative-based Competing Product License by entering into an amendment to this Agreement setting forth in detail the terms of the IGF-1 Derivative-based Competing Product License, which amendment shall provide for, in respect of the IGF-1 Derivative Compound, similar, but separate and distinct, development and sales milestones fees, royalty payment terms and termination provisions as those set forth in this Agreement with respect to the Compound.  Notwithstanding the foregoing, at any time after entering into such Amendment, ACADIA may, in its sole discretion, terminate the IGF-1 Derivative-based Competing Product License. Neuren, and Affiliates, sublicensees and successors shall be bound by the terms of this clause 8, including any Competing Product License, unless ACADIA has terminated the IGF-1 Derivative-based Competing Product License. Notwithstanding the foregoing, provided that Neuren has, in any licence or sublicence agreement relating to an IGF-1 Derivative-based Compound, affirmatively obligated the licensee or sublicensee to comply with clause 8.1(d) above, and such licensee or sublicensee has breached such obligation, Neuren shall have […***…] calendar days following the date of such breach to cause such licensee or sublicensee to cease

Licence Agreement ½Page 24

*** Confidential Treatment Requested

such breach. For the avoidance of doubt, any failure to do so within such period shall mean that the consequences of this clause 8.3 shall have come into effect as of the date of the initial breach.

(b) Prior to commencing, or upon becoming aware of the commencement by a sublicensee of, any preparatory clinical and regulatory development activities that could reasonably be expected to lead to the breach of clause 8.1(d) by it or its Affiliates, licensees or sublicensees or any third party, Neuren shall provide ACADIA with a reasonably detailed written report describing the then-current status of all such activities.

15.13 Equitable Relief

Given the nature of the Confidential Information and the competitive damage that a party would suffer upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the parties agree that monetary damages would not be a sufficient remedy for any breach of this clause 15.  In addition to all other remedies, a party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this clause 15.

16 Improvements

16.1 Improvements

If Neuren or ACADIA makes any Improvement, Neuren or ACADIA (as applicable) will forthwith disclose the same to the other party.

16.2 Improvements solely made by Neuren

If the Improvement is solely made by or on behalf of Neuren or any of its Affiliates (a “Neuren Improvement”), it will automatically form part of the Neuren IP upon the creation or acquisition of such Neuren Improvement by or on behalf of Neuren or its Affiliate (and test results and data within any such Neuren Improvement shall be subject to clause 5.7).

16.4 Improvements made jointly by Neuren and ACADIA

Each party shall have the unrestricted right to practice and use any Joint Improvement to make, have made, use, sell, offer for sale and import products; provided that with respect to Products, in the case of ACADIA, such rights shall be exclusive in the Territory, and in the case of Neuren, exclusive outside of the Territory, and rights to Joint Improvements shall be subject to any rights and licenses granted by one party to the other party hereunder.  Neither party shall have an obligation to obtain the other party’s consent or account to the other with respect to the exploitation of such Joint Improvement or the grant of any right or license to any other person to use or practice any Joint Improvement.

(a) If ACADIA requires any Neuren Improvement or Joint Improvement patent to be applied for in any country in the Territory, ACADIA will notify Neuren of this, and Neuren must notify ACADIA within […***…] days of such a request whether or not Neuren will file the patent application in some or all of the requested countries.  If Neuren elects to file the patent application, Neuren will promptly file the patent application in those countries that ACADIA requests, and take all actions necessary to achieve registration of those patents in a timely manner, provided however that:

(i) all costs in applying for, prosecuting and registering such patent applications and maintaining any patents that issue thereon must be borne by Neuren; and

(ii) ACADIA acknowledges that all such patent applications will be made in the name of Neuren or an Affiliate of Neuren.

(b) Once such patent applications have been filed, they will automatically form part of the Patents licensed to ACADIA by Neuren under this Agreement.

(c) If Neuren elects not to file for such patent application in any country in the Territory, Neuren shall promptly assign its interest in the Neuren Improvement or Joint Improvement and any rights to file for such patent applications to ACADIA and ACADIA may itself apply for, prosecute and register those patent applications and maintain any patents that issue thereon in such country in the Territory at its own cost and in its own name and ACADIA will own any and all rights therein (and the foregoing shall no longer be included in Neuren Improvements or Joint Improvements, as applicable).

17.3 Obligations in respect of Patents

(b) In the event that Neuren desires to abandon or cease prosecution or maintenance of any Patent in the Territory, Neuren shall provide reasonable prior written notice to ACADIA of such intention to abandon (which notice shall, to the extent possible, be given no fewer than […***…] days prior to the next deadline for any action that must be taken with respect to any such Patent in the relevant patent office).  In such case, at ACADIA’s sole discretion, upon written notice from ACADIA to Neuren, ACADIA may elect to continue prosecution or maintenance of any such Patent at its own expense, and Neuren shall execute such documents and perform such acts, at Neuren’s expense, as may be reasonably necessary to effect an assignment of Neuren’s entire right, title, and interest in and to such Patent in the Territory to ACADIA.  Any such assignment shall be completed in a timely manner to allow ACADIA to continue prosecution and maintenance of any such Patent in the Territory and any such Patent so assigned shall cease to be either a Patent and shall no longer be subject to any rights granted by ACADIA to Neuren under this Agreement.

18 Infringement of IP and Proceedings

18.1 Reporting infringement of Neuren IP

Upon either party becoming aware of any use by any other person of a method of manufacture of any Product, a product, mode of advertising or design which might reasonably amount to infringement of any of the Neuren IP or to unfair competition or passing off or any other equivalent or similar breach of any applicable law within the Territory, that party will promptly report to the other party particulars.  

18.2 Allegations of invalidity of Neuren IP

If it comes to the notice of either party that any person alleges that any part of the Neuren IP is invalid, infringes any rights of that person, or is open to any other form of attack, that party will not make any admission but will promptly report the matter in full detail to the other party.  

18.3 Conduct of proceedings with respect to Neuren IP

(a) Subject to clause 18.3(c), if within […***…] days after reporting under clause 18.1 the parties fail to agree on a joint course of action with respect to an Infringement claim that specifically relates to any Product in the Field in the Territory (“Infringement Claim”), ACADIA will have the first right to undertake the defence or prosecution of the Infringement Claim (“Infringement Defence”).

(b) Should ACADIA undertake any Infringement Defence, Neuren will fully co-operate with ACADIA in relation to such Infringement Defence, including, if required to bring such action, the furnishing of a power of attorney or being named as a party, and the costs and expenses of any such Infringement Defence will be borne by ACADIA, unless Neuren chooses to participate in such Infringement Defence in which case all parties will bear their own costs of the action.  For the avoidance of doubt and subject to clause 18.3(c), the conduct of any Infringement Defence that ACADIA undertakes in accordance with this clause 18.3 shall be controlled by ACADIA.  Unless otherwise agreed in writing as part of any cost-sharing arrangement, any recoveries resulting from such Infringement Defence shall be applied as follows:

Licence Agreement ½Page 36

*** Confidential Treatment Requested

(i) first, to reimburse each party for all out-of-pocket costs incurred by such party in connection with such Infringement Defence (on a pro rata basis, based on each party’s respective litigation costs, to the extent the recovery was less than all such litigation costs); and

(ii) second, any remainder shall be retained by ACADIA, except that such amounts shall be regarded as Net Revenues and any applicable Royalty thereon paid to Neuren.

(c) Should the defence or prosecution of any Infringement Defence undertaken by ACADIA also involve an Invalidity Claim (“Infringement and Invalidity Defence”):

(i) Neuren and/or its Affiliates and any of Neuren’s or its Affiliates’ third party licensees of any of the Neuren IP at issue outside the Territory (“Third Party Licensees”) shall have the right, at their own expense, to be involved in such Infringement and Invalidity Defence as it relates to invalidity issues and ACADIA will make no admissions which would materially prejudice Neuren’s or its Affiliates’ or any Third Party Licensees’ rights in such Neuren IP without the written consent of Neuren, not to be unreasonably withheld;

(ii) any amounts recovered under an Infringement and Invalidity Defence that Neuren and/or its Affiliates or Third Party Licensees participate in, will be shared in the same manner as set out in clause 18.3(b); and

(iii) other than for matters involving admissions which would materially prejudice Neuren’s or its Affiliates’ or any Third Party Licensee’s rights in such Neuren IP, the conduct of any Infringement and Invalidity Defence that ACADIA undertakes in accordance with this clause 18.3 shall be controlled by ACADIA in the same manner as an Infringement Defence.  

(d) If within […***…] days after reporting under clause 18.2, the parties fail to agree on a joint course of action with respect to a claim or allegation challenging the validity, scope or enforceability of any Patent in the Territory or opposition proceeding against any Patent in the Territory, including inter partes review proceedings before PTAB or a similar tribunal in the Territory (“Invalidity Claim”), other than an Invalidity Claim that is part of any Infringement and Invalidity Defence pursuant to clause 18.3(c), ACADIA will have the first right to undertake the defence or prosecution of the Invalidity Claim (“Invalidity Defence”), provided that Neuren and its Affiliates and any Third Party Licensees shall have the right to participate in such action on the same conditions as an Infringement and Invalidity Defence as specified in clause 18.3(c), and the Invalidity Defence shall be conducted on the same conditions as an Infringement and Invalidity Defence as specified in clause 18.3(c).  Any amounts recovered under an Invalidity Defence that Neuren, or its Affiliates or Third Party Licensees participate in will be shared in the same manner as set out in clause 18.3(b).

(e) In the event of ACADIA choosing not to undertake any Infringement Defence or Invalidity Defence, Neuren and/or any of its Affiliates may do so on its own behalf and in that event, ACADIA will fully co-operate with Neuren or any of its Affiliates in relation to such action, and the costs and expenses of any such action, including any costs or expenses normally incurred by or on behalf of ACADIA will be borne by Neuren, except as otherwise stated in this Agreement, and the proceeds of any such action will belong to Neuren or any of its Affiliates.  To establish whether ACADIA has chosen to undertake any Infringement Defence or Invalidity Defence, Neuren may at any time after becoming aware of such claim serve a notice on ACADIA requesting ACADIA to specify whether it will undertake the Infringement Defence or Invalidity Defence.  ACADIA will have […***…] Business Days from the date of receipt of such notice, or if later until the date that is:

Licence Agreement ½Page 37

(i) […***…] days following the notice in clause 18.1 or 18.2; or

(ii) […***…] days before the time limit, if any, set forth in the appropriate laws and regulations for the filing or defence of such actions, whichever of clause 18.3(e) (i) or (ii) that comes first, to respond to Neuren in writing.  If ACADIA does not respond to Neuren in writing within the specified time period, ACADIA will be deemed to have undertaken not to undertake the Infringement Defence or Invalidity Defence.  Neither Neuren nor its Affiliate shall settle or compromise any such action or proceeding in any manner that would negatively affect ACADIA’s rights under the Patents in the Territory under this Agreement without the prior written consent of ACADIA, which shall not be unreasonably withheld.

18.4 Infringement of Third Party rights

(a) Each party shall promptly notify the other party in writing of any allegation by a Third Party that the activity of ACADIA, Neuren, or any of their respective Affiliates or Third Party licensees or sub-licensees (or Sub-Licensees), as applicable, pursuant to this Agreement infringes or may infringe the Intellectual Property Rights of a Third Party.  Subject to Neuren’s indemnification obligations, ACADIA shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by activities of ACADIA or its Affiliates or Sub-Licensees at its own expense and by counsel of its own choice, and Neuren shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. Subject to ACADIA’s indemnification obligations, Neuren shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by activities of Neuren or its Affiliates or Third Party licensees or sub-licensees at its own expense and by counsel of its own choice, and ACADIA shall have the right, at its own expense, to be represented in any such action by counsel of its own choice.  

(b) Neither Party shall enter into any settlement of any claim described in this clause 18.4 that negatively affects the other party’s rights or interests without such other party’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed.  Each party shall have the right to decline to defend or to tender defense of any such claim to the other party upon reasonable notice, including if the other party fails to agree to a settlement that such party proposes.
