Joint Inventions, other than those covered in Section 7.2(a) or Section 7.2(b), and, subject to the rights granted each Party under this Agreement, each Party may use, sell, keep, license or assign its interest in Joint Inventions and otherwise undertake all activities a sole owner might undertake with respect to such Joint Inventions, without the consent of and without accounting to the other Party. “Joint Inventions” means Collaboration Inventions for which it is determined, in accordance with the patent law of the United States, that both: (i) one or more employees, consultants or agents of Camurus or any other persons obligated to assign such Collaboration Invention to Camurus; and (ii) one or more employees, consultants or agents of Rhythm or any other persons obligated to assign such Collaboration Invention to Rhythm, are inventors of such Collaboration Invention. For any Joint IP that could be the subject of an application for a Patent Right, each Party, in conjunction with such Party’s patent counsel will make an initial determination of inventorship prior to filing the application therefor to confirm that it is Joint IP. Each Party will provide information and records relevant to such determination to the other Party and such patent counsel

(d)         Subject to appropriate confidentiality undertakings, each Party shall promptly notify the other Party when it learns a Collaboration Invention has been made and promptly after the completion of invention disclosure statements for such Collaboration Invention (or, if any provisional or other patent applications are filed claiming such invention, promptly after such filing), and, to the extent a Party is granted rights hereunder in such Collaboration Invention, shall provide a copy of the same to the other Party.

(e)          For the avoidance of doubt, neither Party is granted any license rights to any intellectual property rights of the other Party, which may be required for such Party to use a Collaboration Invention, unless otherwise expressly granted herein.

(f)           Each of the Parties shall do all such acts and things and execute all such deeds and documents as may be necessary or desirable for them to perfect their rights of ownership as specified in this Section 7.2 and otherwise implement the provisions of this Section 7. Each Party shall, and shall cause its applicable Affiliates, Third Party subcontractors, and their respective employees and agents to, perform at the requesting Party’s cost all reasonable acts reasonably requested, including the execution of confirmatory deeds and assignment documents of Patent Rights as may be necessary or desirable for them to perfect their title therein in accordance with the forgoing provisions of this Section.

7.3                                        Prosecution of Patents.

(a)         Patent Prosecution of Camurus IP. Camurus shall control the Prosecution of the Patent Rights within Camurus Platform IP (“Camurus Platform Patents”) at its own cost and expense using Commercially Reasonable Efforts to Prosecute all patent applications forming part of Camurus Platform Patents to grant with Valid Claims, including conducting any necessary or desirable oral or written proceedings. Camurus shall provide Rhythm with a copy of each new draft application and replies to substantive office actions within the Camurus Platform Patents (including, for clarity, divisional and continuation applications), and shall keep Rhythm informed of all material developments in relation to Camurus

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

Platform Patents and shall provide Rhythm with copies of relevant documents related to the Prosecution of Camurus Platform Patents in the United States and EU and any PCT application. Camurus shall provide relevant documents related to the Prosecution of the Camurus Platform Patents in all other countries in the Territory upon request from Rhythm. In the event that, having filed, Camurus declines to further Prosecute any Camurus Platform Patents in any country of the Territory, Camurus shall provide Rhythm with written notice thereof. Such notice shall be given at least sixty (60) days prior to the expiration of any official substantive deadline relating to such activities. In any such circumstances and provided that no earlier licensee of Camurus has assumed the right to Prosecute such Camurus Platform Patents Rhythm shall have the right to decide that Rhythm should continue to Prosecute such Camurus Platform Patents owned by Camurus at Rhythm’s expense and in such case Rhythm shall give written notice to Camurus; provided that if Camurus’ decision to decline to further Prosecute any pending Camurus Platform Patents is as a result of the withdrawal of an unpublished patent application and the reason for such withdrawal was to enable the filing of another patent application claiming the same inventions, Rhythm shall not have the right to decide that Rhythm should continue to Prosecute the withdrawn unpublished patent application. Camurus shall upon receipt of any such notice from Rhythm transfer to Rhythm copies of all of its files relating to the relevant Camurus Platform Patents and at Rhythm’s reasonable cost and expense execute any documents to otherwise transfer control of such Prosecution to Rhythm. Camurus shall remain the owner of such Camurus Platform Patents and Rhythm shall provide Camurus the same information and rights required under this Section 7.3(a) to be provided Rhythm concerning the Prosecution of such Camurus Platform Patents. Rhythm may deduct the prosecution costs with respect to such Camurus Platform Patents from the royalties payable to Camurus under this Agreement. This Section 7.3 (a) shall apply mutatis mutandis to Patent Rights within Collaboration Inventions solely owned by Camurus pursuant to Section 7.4.

(b)         Patent Prosecution of Collaboration Product Patents and Rhythm Product Patents in the Territory. Rhythm shall control the Prosecution of (i) the Patent Rights to any and all Collaboration Inventions owned by Rhythm pursuant to Section 7.2(b), Section 7.2(c) if solely owned by Rhythm or Section 7.4 (jointly “Collaboration Product Patents”), and (ii) the Rhythm Product Patents, in the Territory at Rhythm’s expense using Commercially Reasonable Efforts to Prosecute all patent applications forming part of the Collaboration Product Patents to grant with Valid Claims, including conducting any necessary or desirable claims or oral or written proceedings. With respect to the Collaboration Product Patents, Rhythm shall provide Camurus the same information and rights required under Section 7.3(a) to be provided Rhythm concerning the Prosecution of the Camurus Platform Patents. In the event that, having filed, Rhythm declines to further Prosecute any Collaboration Product Patents in any country in the Territory, Rhythm shall provide Camurus with written notice thereof.  Such notice shall be given at least sixty (60) days prior to the expiration of any official substantive deadline relating to such activities. In any such circumstances Camurus shall have the right to decide that Camurus should continue to Prosecute such Collaboration Product Patents at Camurus’ expense and in such case Camurus shall give written notice to Rhythm. Rhythm shall upon receipt of any

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

such notice from Camurus transfer to Camurus all of its files relating to the relevant Collaboration Product Patents and at Camurus’ reasonable cost and expense execute any documents to otherwise transfer control of such Prosecution to Camurus.  Rhythm shall remain the owner of such Collaboration Product Patents and Camurus shall provide Rhythm the same information and rights required to be provided Camurus under this Section 7.3(b) concerning the Prosecution of such Collaboration Product Patents.

(c)          Joint Patents. With respect to the Prosecution of patent applications claiming Joint Inventions subject to Section 7.2(c) (“Joint Patents”), Rhythm shall have the right to take such actions as are necessary or appropriate to Prosecute Joint Patents at its sole expense; provided, that all such patent applications and patents shall be owned jointly. Rhythm shall furnish Camurus with copies of such Joint Patents and other related correspondence relating to such Joint Inventions to and from patent offices throughout the Territory and permit Camurus to offer its comments thereon before Rhythm makes a submission to a patent office. Rhythm shall inform Camurus of the countries in which it intends to file patent applications. Camurus shall offer its comments promptly, including any request that the patents be filed in additional countries; provided, that Rhythm shall determine the appropriate action after considering in good faith any comments or requests from Camurus, and further provided that in the event that delay would jeopardize any potential patent right, Rhythm shall have the right to proceed without awaiting Camurus’ comments. If Rhythm determines in its sole discretion not to Prosecute any patent or patent application within the Joint Patents in any country, and provided that no other patent applications or patents claiming the same or similar subject matter are then pending or issued in that same country, then Rhythm shall provide Camurus with sixty (60) days prior written notice (or such shorter time period that would permit Camurus a reasonable opportunity to respond in a timely manner) of such determination and Camurus shall have the right and opportunity to Prosecute such patent application or patent on behalf of the Parties at Camurus’ sole cost and expense. Camurus shall provide Rhythm the same information and rights required under this Section 7.3(c) to be provided Camurus concerning the Prosecution of such Joint Patents.

(d)         As promptly as practicable after the Effective Date (but in no event later than one hundred and twenty (120) days after the Effective Date), Rhythm shall file a patent application with the United States Patent and Trademark Office [           ]*.  Camurus shall provide Rhythm with such information and/or invention disclosures reasonably requested by Rhythm, and shall otherwise cooperate with all reasonable requests made by Rhythm, in connection with the preparation, filing and prosecution of such patent application.  Notwithstanding anything express or implied anywhere else in this Agreement, all of the inventions claimed in such patent application (other than those of such inventions that are already owned solely by Rhythm as of the Effective Date) shall be deemed and treated, for all purposes of this Agreement, as Collaboration Inventions that are owned solely by Rhythm pursuant to Section 7.2(b) hereof.  For clarity, such patent application and all other Patent Rights related to those inventions that are deemed and treated, for all purposes of this Agreement, as Collaboration Inventions shall be deemed and treated as Collaboration Product Patents for all purposes of this Agreement and be subject inter alia to Section 7.3 (b).

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

(e)          Each Party shall at the expense of the requesting Party execute such documents and take such other actions as may be reasonably requested by the other Party in conjunction with prosecution of patents pursuant to this Section 7.3.

7.4                                        Camurus Platform Patents and Collaboration Product Patents.  If, after the Effective Date, any Collaboration Invention relates both to [           ]*, on the one hand, and [           ]*, on the other hand, and patent claims can be made based on the same data, Patent Right or study result, where appropriate Camurus shall, in consultation with Rhythm, file separate patent applications on the same day to any aspect relating to [           ]*, on the one hand, and [           ]*, on the other hand, separately. Any such applications relating specifically to [           ]* shall become part of the Rhythm Collaboration IP and, therefore, shall be exclusively owned by Rhythm, and any such applications relating to [           ]* shall become part of Camurus Platform IP hereunder and, therefore, shall be exclusively owned by Camurus.  In the event that the provisions of this Section 7.4 are applicable to any Collaboration Invention, the provisions of this Section 7.4 shall be applied to such Collaboration Invention before the provisions of any of Section 7.2(a) or Section 7.2(b) are given effect with respect to such Collaboration Invention.

7.5                                        Employee Assignment. Each Party shall ensure that any employee of that Party involved in the performance of this Agreement shall be employed on legally binding written terms which require the assignment of all Patent Rights and Know-How resulting from work carried out by that employee to the employing Party. Each Party shall be responsible for all payments to its employees or others in respect of obtaining rights to any such Patent Rights and Know-How.

7.6                                        Patent Term Extensions. For all patents within any Patent Rights relating to or claiming a Product for which NDA Approval has been obtained, the Parties shall use reasonable efforts, in each country where NDA Approval for a Product has been obtained and the law of such country permits application for a patent term extension (or any supplementary certificate), to apply for a patent term extension (or any supplementary certificate) for one or more selected patent within such Patent Rights chosen at Rhythm’s reasonable discretion with respect to the Territory. Each Party agrees to cooperate with the other Party in the exercise of the authorizations granted under this Section, and to execute such documents and take such additional action as the other Party may reasonably request in connection therewith.

7.7                                        Third Party Intellectual Property. Each Party shall bring to the attention of the other Party all information regarding potential infringement or misappropriation of Third Party Patent Rights as a result of the manufacture, use, importation, offer for sale, or sale of Product in the Territory.  The Parties shall discuss such information and decide how to handle the matter.  This Section 7.7 shall not be interpreted as placing on either Party a duty of inquiry regarding Third Party Intellectual Property rights beyond what is customary for the industry.

7.8                                        Third Party Infringement.  In the case where either Party believes that the development, manufacture, use or sale of the Product or a Competing Product by a Third Party in the Licensed Field infringes any Camurus Platform Patents, any other Patent Rights licensed by Camurus to Rhythm pursuant to this Agreement,

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

any other Collaboration Product Patents covering the Product (including any method of making or using the same) or the Joint Patents (each, an “Infringing Activity”), such Party shall disclose full details of the potential infringement to the other Party.  In addition, if either Party believes that development, manufacture, use or sale of the Product or a Competing Product by a Third Party in the Licensed Field infringes any other Patent Rights covering the Product, such Party shall disclose full details of the potential infringement to the other Party. The right to prosecute Infringing Activity pursuant to this Agreement is set out in either Section 7.9 or Section 7.10, as applicable.  If the Parties fail to agree with respect to whether an Infringing Activity is subject to Section 7.9 or Section 7.10, the dispute will be referred to a Third Party U.S. patent attorney acceptable to each of the Parties for Expert Determination as provided in Exhibit 7.2(c).  For the avoidance of doubt, it is understood and agreed that in this section 7.8 and in Section 7.9, Patent Rights claiming the Product do not include Rhythm Product Patents or any other Patent Rights owned or Controlled by Rhythm (other than Collaboration Product Patents).

7.9                                        Enforcement with respect to Collaboration Product Patents and Joint Patents.  Where an infringement of (x) any Patent Rights specifically claiming the Product (including any method of making or using the same) or (y) any Joint Patents by an Infringing Activity occurs in one or more countries of the Territory, Rhythm shall have the first right to, but shall not be obliged to, at its own cost and expense enforce the same in accordance with the below subparagraphs (i) to (iii).

(i) Rhythm shall have sole conduct of the claim and any proceedings including any counterclaim for invalidity or unenforceability or any declaratory judgment action and including the right to settle. Where Rhythm decides to commence proceedings in relation to any such Patent Rights claiming specifically the Product (including any method of making or using the same) or any Joint Patents it shall be entitled to require Camurus to join Rhythm as co-plaintiff and Camurus shall have the right to join as co-plaintiff.  In such case Camurus shall provide all necessary assistance to Rhythm in relation to any such proceeding and Rhythm shall on demand by Camurus pay or promptly reimburse Camurus for the costs of such activity unless Camurus elects to be separately represented (which shall be at Camurus’ discretion), in which case such separate representation shall be at Camurus’ cost and expense;

(ii) if Rhythm succeeds in any such infringement proceedings whether at trial or by way of settlement, the proceeds of any award or damages or settlement in respect of such infringement proceedings shall first be applied to reimburse (a) an amount equal to Rhythm’ costs of taking the proceedings and (b) an amount equal Camurus’ costs, with the remainder being retained by Rhythm less [           ]* per cent [           ]* thereof, which amount shall be paid to Camurus;

(iii) if Rhythm fails to take any such proceedings in respect of any such Patent Rights claiming specifically the Product (including any method of making or using the same) or any Joint Patents in the Territory, Camurus may give Rhythm written notice requesting Rhythm to take such proceedings within thirty (30) days of the date of notice and if Rhythm fails to take such action within said period, Camurus shall, subject to the prior written consent of Rhythm, be entitled to do so at its own cost and expense.  If Rhythm gives such consent then Camurus shall be entitled to

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

require Rhythm to join Camurus as co-plaintiff and Rhythm shall have the right to join as co-plaintiff.  In such case, Rhythm shall provide all necessary assistance to Camurus in relation to such proceedings and Camurus shall on demand by Rhythm pay or promptly reimburse Rhythm for the costs of such activity, unless Rhythm elects to be separately represented (which shall be at Rhythm’ discretion), in which case such separate representation shall be at Rhythm’s cost and expense.  If Camurus succeeds in any such proceedings, the proceeds of any award or damages or settlement in respect of such proceedings shall first be applied to reimburse (a) an amount equal to Camurus’ costs of taking the proceedings and (b) an amount equal Rhythm’ costs referred to in this Section 7.9(iii), with the remainder being retained by Camurus, less [           ]* per cent [           ]* thereof, which amount shall be paid to Rhythm. Camurus shall not enter into a settlement, consent judgment or other voluntary final disposition of an action or claim or counterclaim under this Section 7.9 without the prior written approval of Rhythm, such consent not to be unreasonably withheld. For the avoidance of doubt, it is understood and agreed that in this Section 7.9, Patent Rights specifically claiming the Product (including any method of making or using the same) do not include Rhythm Product Patents or any other Patent Rights owned or Controlled by Rhythm (other than Collaboration Product Patents).

7.10                                 Enforcement with respect to Camurus Platform Patents.  Where an infringement of Camurus Platform Patents not specifically claiming the Product (including any method of making or using the same) by an Infringing Activity is occurring in one or more countries of the Territory, Camurus shall have the right, but shall not be obliged, at its own cost and expense to enforce the same.  Camurus shall be entitled to require Rhythm to join Camurus as co-plaintiff. In such case Rhythm shall provide all necessary assistance to Camurus in relation to any such proceeding and Camurus shall on demand by Rhythm pay or promptly reimburse Rhythm for the costs of such activity.  If Camurus succeeds in any such infringement proceedings whether at trial or by way of settlement, the proceeds of any award or damages or settlement in respect of such infringement proceedings shall first be applied to reimburse (a) an amount equal to Camurus’ costs of taking the proceedings and (b) an amount equal Rhythm’s costs, if any, with the remainder being retained by Camurus less [           ]* per cent [           ]* thereof, which amount shall be paid to Rhythm.  Camurus shall have the sole right to settle such proceedings, provided that such settlement does not include a license or covenant not to sue under the Camurus Platform IP or causes Rhythm to incur any losses in which case Rhythm’s consent to the terms of such license shall be required, such consent not to be unreasonably withheld, conditioned or delayed. If Camurus elects not to enforce any such Camurus Platform Patents, then Rhythm shall have the right, but shall not be obliged, at its own cost and expense to do so in accordance with the following, subject to the prior written consent of Camurus.  If Camurus gives such consent, then the following procedures shall apply in these circumstances:

(i) Where Rhythm has requested and been granted approval by Camurus to commence proceedings in relation to any such Camurus Platform Patents not specifically claiming the Product (including any method of making or using the same), Rhythm shall be entitled to require Camurus to join Rhythm as co-plaintiff and Camurus shall have the right to join as co-plaintiff.  In such case Camurus shall provide all necessary assistance to Rhythm in relation to any such proceeding and

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

Rhythm shall on demand by Camurus pay or promptly reimburse Camurus for the costs of such activity unless Camurus elects to be separately represented (which shall be at Camurus’ discretion), in which case such separate representation shall be at Camurus’ cost and expense;

(ii) if Rhythm succeeds in any such infringement proceedings whether at trial or by way of settlement, the proceeds of any award or damages or settlement in respect of such infringement proceedings shall first be applied to reimburse (a) an amount equal to Rhythm’ costs of taking the proceedings and (b) an amount equal to Camurus’ costs referred in this Section 7.10, with the remainder being retained by Rhythm less [           ]* per cent [           ]* thereof, which amount shall be paid to Camurus;

(iii) Rhythm shall not enter into a settlement, consent judgment or other voluntary final disposition of an action or claim or counterclaim under this Section 7.10 without the prior written approval of Camurus, such consent not to be unreasonably withheld.

7.11                                 Hatch-Waxman Certifications.  If either Party (i) reasonably believes that a Third Party may be filing or preparing or seeking to file a generic or abridged NDA that refers to or relies on regulatory documentation for a Product that was submitted by Rhythm to any Regulatory Authority, (ii) receives any notice of certification regarding any Patent Rights included in Camurus Patent Rights (i.e., Patent Rights Controlled by Camurus) or Rhythm Patent Rights (i.e., Patent Rights Controlled by Rhythm) pursuant to the Hatch-Waxman Act claiming that any such Patent Rights are invalid or unenforceable or claiming that the any such Patent Rights will not be infringed by the manufacture, use, marketing or sale of a product for which an ANDA is filed, or (iii) receives any equivalent or similar certification or notice in any other jurisdiction, it shall notify the other Party in writing, identifying the alleged applicant or potential applicant and furnishing the information upon which such determination is based, and provide the other Party a copy of any such notice of certification within five (5) days of receipt and the Parties’ rights and obligations with respect to any legal action as a result of such certification shall be as set forth above in Sections 7.9 or 7.10.

8                                                  CONFIDENTIALITY

8.1                                        Except to the extent expressly authorized by this Agreement including in Sections 8.3 and 8.4 or otherwise agreed in writing, each Recipient and its Affiliates and its Sublicensees and licensees in possession of Confidential Information of the Disclosing Party shall maintain such Confidential Information as confidential and use it only for the purposes of this Agreement in accordance with this Section 8. This obligation shall continue during the term of this Agreement and for a period equal to ten (10) years after the date of expiration or termination of this Agreement; provided, however, that this obligation shall continue to apply after such ten (10) year period to any Know-How, development data, other data, regulatory filings and other information disclosed, provided, licensed, transferred or otherwise made available by either Party to the other Party under this Agreement, until such time as such Know-How, development data, other data, regulatory filings and other information becomes exempt pursuant to subparagraphs (i) through (v) below. Each

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

Party shall guard such Confidential Information using the same degree of care as it normally uses to guard its own confidential, proprietary information of like importance, but in any event no less than reasonable care.  Notwithstanding the foregoing, the Recipient of the categories of Confidential Information identified in Sections 1.16 (i)-(iv) inclusive shall be relieved of the confidentiality and limited use obligations of this Agreement to the extent that the Recipient establishes by written evidence that:

(i)  the Confidential Information was previously known to the Recipient from sources other than the Disclosing Party at the time of disclosure and other than under an obligation of confidentiality and non-use;

(ii) the Confidential Information was generally available to the public or otherwise part of the public domain at the time of its disclosure; or

(iii) the Confidential Information became generally available to the public or otherwise part of the public domain after its disclosure to the Recipient Party other than through any act or omission of the Recipient Party in breach of this Agreement; or

(iv) the Confidential Information is acquired in good faith in the future by the Recipient Party from a Third Party who has a lawful right to disclose such information and who is not under an obligation of confidence to the Disclosing Party with respect to such information; or

(v) the Confidential Information is subsequently developed by or on behalf of the Recipient Party without use of the Disclosing Party’s Confidential Information.

8.2                                        For clarity, specific aspects or details of Confidential Information shall not be deemed to be within the public domain or in the possession of the Recipient Party merely because the Confidential Information is embraced by more general information in the public domain or in the possession of the Recipient Party. Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of the Recipient Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the Recipient Party unless the combination is in the public domain or in the possession of the Recipient Party.

8.3                                        Notwithstanding the above obligations of confidentiality and non-use a Recipient may disclose Confidential Information:

(i) to a Regulatory Authority as reasonably necessary to obtain and maintain Regulatory Approval in a particular jurisdiction to the extent consistent with the licenses granted under terms of this Agreement, provided that reasonable effort will be taken to ensure confidential treatment of such information.

(ii) disclose Confidential Information: (a) to the extent such disclosure is reasonably necessary to comply with the order of a court; or (b) to the extent such disclosure is required to comply with a legal requirement, including to the extent such disclosure is required in publicly filed financial statements or other public statements or filings under rules governing a stock exchange or pursuant to

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

applicable securities laws or regulations (e.g., the rules of the United States Securities and Exchange Commission, NASDAQ, NYSE, or any other stock exchange on which securities issued by either Party may be listed); provided, to the extent possible bearing in mind such legal requirements and subject to the next subsequent sentence of this Section 8.3.(ii), such Party shall provide the other Party with a copy of the proposed text of such statements or disclosure five (5) business days in advance of the date on which the disclosure is to be made to enable the other Party to review and provide comments, unless a shorter review time is agreed. If compliance with a legal requirement requires filing of this Agreement, the filing Party shall to the extent possible seek confidential treatment of portions of this Agreement from the relevant competent authority to the extent that such confidential treatment is available pursuant to applicable law and shall provide the other Party with a copy of the proposed filings at least five (5) business days prior to filing for the other Party to review any such proposed filing and provide comments. Each Party agrees that it will obtain its own legal advice with regard to its compliance with legal requirements and will not rely on any statements made by the other Party relating to such legal requirements; and

(iii) by filing or prosecuting Patent Rights, the filing or prosecution of which is contemplated by this Agreement, without violating Section 8.1; it being understood that publication of such filings occurs in some jurisdictions within eighteen (18) months of filing, and that such publication shall not violate the above secrecy provision.

(iv) to such Recipient’s employees, Affiliates, contractors (including clinical researchers and CMO’s), licensees, sublicensees, agents, consultants and potential business partners, as such Recipient reasonably determines is necessary to receive the benefit of the licenses and rights granted or available to it under this Agreement or to fulfill its obligations pursuant to this Agreement; provided, however, any such persons must be obligated to substantially the same extent as set forth in Section 8.1 to hold in confidence and not make use of such Confidential Information for any purpose other than those permitted by this Agreement and breach by such persons of their confidentiality obligations shall be deemed a breach by the Recipient of its confidentiality obligations hereunder.  For the avoidance of doubt, it is understood and agreed that Camurus may not disclose any Confidential Information relating to the Product to any licensee of the FC Technology without the prior written consent of Rhythm except when exercising its rights under Sections 2.4 and 3.7.

(v) (a) to its actual or potential investment bankers; (b) to existing and potential investors in connection with an offering or placement of securities for purposes of obtaining financing for its business and to actual and prospective lenders for the purpose of obtaining financing for its business and to potential licensees or sublicensees of the FC Technology or any other rights licensed to the Recipient pursuant to this Agreement; and (c) to a bona fide potential acquirer or merger partner for the purposes of evaluating entering into a merger or acquisition, provided, however, any such persons must be obligated to substantially the same extent as set forth in Section 8.1 to hold in confidence and not make use of such Confidential Information for any purpose other than those permitted by this Agreement; and

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

(vi) disclose Confidential Information to its legal advisers for the purpose of seeking advice.

8.4                                        Nothing in this Section 8 restricts either Party from using or disclosing any of its own Confidential Information for any purpose whatsoever; provided that, to the extent Know-How is exclusively licensed by one Party to the other, the licensor may not continue to use and disclose such Know-How in a manner not consistent with the exclusivity of the license granted.

8.5                                        Other than the press release pertaining to this transaction that the Parties have agreed upon and attached as Exhibit 8.5 to this Agreement and save as permitted in Section 8.3:

(i) neither Party, as a Recipient, shall make any public announcement or statement to the public containing Confidential Information of the Disclosing Party without the prior written consent of the Disclosing Party.  No such public announcements or statements shall be made without the prior review and consent of the appropriate individual designated for the purpose by the other Party; and

(ii) save as may otherwise be provided herein neither Party shall mention or otherwise use the name or Trademark of the other Party or its Affiliates in any publication, press release, promotional material or other form of publicity without the prior written consent of the appropriate individual designated for the purpose by the other Party.

8.6                                        With respect to public disclosure required to be made pursuant to regulatory requirements or stock exchange rules applicable to a Party, each such Party will use reasonable efforts to submit to the other Party a draft of any public announcement (“Proposed Disclosure”) directly related to the Product at least three (3) business days prior to the date on which such Party plans to make such announcement, and in any event will submit such draft to the other Party at least twenty-four (24) hours prior to the release of such Proposed Disclosure. If a Party is unable to comply with the foregoing twenty-four (24)-hour notice requirement because of a legal obligation or stock or securities exchange requirement to make more rapid disclosure, such Party will not be in breach of this Agreement but will in that case give telephone and email notice to a senior executive of the other Party and provide a draft of the Proposed Disclosure with as much notice as possible prior to the release of such announcement.  A Party that receives a draft of any Proposed Disclosure that the other Party is planning to make may not make any disclosure or public announcement of the substance or content of such Proposed Disclosure until such time as such other Party has released such Proposed Disclosure to the public.  Any draft of any Proposed Disclosure provided by one Party to the other pursuant to this Section 8.6 shall be deemed and treated as Confidential Information of the Party that is proposing to make such Proposed Disclosure.

8.7                                        Notwithstanding the foregoing Camurus shall be entitled to include the name of Rhythm within a list of collaborators.

Termination of this Agreement pursuant to this Section 11.3(c) will be without prejudice to any rights that will have accrued to the benefit of a Party prior to the effective date of such termination. Such termination will not relieve a Party from obligations that are expressly indicated to survive the termination of this Agreement.

(e)          Rhythm may also terminate this Agreement in accordance with the provisions of Sections 3.6 and 5.2, and if Rhythm fails to deliver notice of termination or continuation to Camurus in accordance with the time periods specified in Sections 3.6 and 5.2 then Camurus may terminate this Agreement with immediate effect by giving written notice to Rhythm.

(f)           In case of termination without cause, neither party shall be liable to the other party for any compensation or damages by reason of such termination of this Agreement.

12.11                          Severability.  Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement and the Parties shall in good faith seek to agree on an alternative provision reflecting the intent of the Parties that is enforceable.

12.12                          Entire Agreement.  This Agreement shall constitute and contain the complete, final and exclusive understanding and agreement of the Parties and cancels and supersedes any and all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties with respect to the subject matter hereof.

For Camurus: Chief Executive Officer

For Rhythm: Chief Executive Officer

* CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

(b)         In the event that they shall be unable to resolve the dispute by executive mediation within such sixty (60) day period and do not mutually agree to extend the time for negotiation, then subject to Section 3.4 and Section 7.2(b), the dispute shall be submitted to and finally settled by binding arbitration in accordance with the procedure set forth in Sections 12.14(c)-(d).

(c)          Except with respect to actions by either Party seeking equitable or declaratory relief as described in Section 12.14(e), any claim or controversy arising in whole or in part under or in connection with this Agreement or the subject matter hereof that is not resolved pursuant to Section 12.14(b) or Section 3.4 or Section 7.2, as applicable, will be referred to and finally resolved by arbitration in accordance with the Rules of the International Chamber of Commerce (the “Rules”) as such Rules may be modified by this Agreement, by one arbitrator, who will be agreed upon by the Parties.  If the Parties are unable to agree upon a single arbitrator within thirty (30) days following the date arbitration is demanded, three arbitrators will be used, one selected by each Party within ten (10) days after the conclusion of the 30-day period and a third selected by the first two within ten (10) days thereafter.  The arbitrator(s) will resolve any discovery disputes.  Either Party may commence arbitration proceedings by notice to the other Party.  The Arbitration Institute of International Chamber of Commerce shall administer any arbitration proceeding. The place of arbitration shall be London, England. The arbitration shall be conducted in English. The award of arbitration shall be final and binding upon both Parties.

(d)         Except to the extent otherwise expressly provided in this Agreement, the arbitrator(s) will apply the laws of England.  Judgment on the award granted in any arbitration hereunder may be entered in any court having jurisdiction over the award or any of the Parties or any of their respective assets.  The Parties knowingly and voluntarily waive their rights to have their dispute tried and adjudicated by a judge and jury except as expressly provided herein.

(e)          Nothing in this Section 12.14 will prevent a Party from resorting to judicial proceedings if:  (i) interim relief from a court is necessary to prevent serious and irreparable injury to such Party; or (ii) litigation is required to be filed prior to the running of the applicable statute of limitations.  The use of any alternative dispute resolution procedure will not be construed under the doctrine of latches, waiver or estoppel to affect adversely the rights of either Party.  Despite such action the Parties shall continue to participate in good faith in the procedures specified in this Section 12.14.

12.15                          Independent Contractors.  Nothing herein shall be construed to create any relationship of employer and employee, agent and principal, partnership or joint venture between the Parties.  Each Party is an independent contractor.  Neither Party shall have authority to make any statements, representations, or commitments of any kind, or to take any action which shall be binding on the other Party, except as may be explicitly provided for herein or otherwise authorized in writing.

PRESS RELEASE

13                                           Rhythm and Camurus Announce License Agreement for Extended Release FluidCrystal Setmelanotide

BOSTON and LUND, Sweden, January 5, 2016— Rhythm and Camurus announced today a license agreement for the use of Camurus’ drug delivery technology, FluidCrystal®, to formulate setmelanotide (RM-493), Rhythm’s novel melanocortin-4 receptor (MC4R) agonist. Under the terms of the agreement, Camurus has granted Rhythm a worldwide license to the FluidCrystal technology to formulate setmelanotide and to develop, manufacture, and commercialize this new formulation that has the potential for once-weekly dosing, administered as a subcutaneous injection. Rhythm plans to initiate a Phase I clinical trial with the setmelanotide FluidCrystal formulation after completing GMP manufacturing.

“We have developed a setmelanotide formulation with Camurus with an impressive sustained-duration profile,” said Bart Henderson, President of Rhythm. “We believe this new formulation will provide a significant benefit to patients, improving compliance and ease of use with once-weekly dosing.”

“The partnership with Rhythm follows the formulation development and preclinical assessment of this compelling drug candidate based on our FluidCrystal Injection depot technology,” said Fredrik Tiberg, President and CEO of Camurus. “Rhythm’s setmelanotide represents a novel approach to treating patients suffering from life-threatening obesity due to these rare and serious genetic disorders.”

The license granted to Rhythm is specific to the FluidCrystal technology incorporating setmelanotide. The formulation has been developed in a collaboration between the companies. Under the terms of the license agreement, Rhythm is responsible for manufacturing, development, and commercialization of the setmelanotide FluidCrystal formulation worldwide. Camurus is eligible to receive an upfront payment and progressive payments of approximately $65 million, of which the majority are sales milestones. In addition, Camurus is eligible to receive tiered, mid to mid-high, single digit royalties on future sales of the product.

About Setmelanotide (RM-493)

Setmelanotide is a potent, first-in-class MC4R agonist in development for the treatment of obesity caused by genetic deficiencies in the MC4 pathway, a key pathway in humans that regulates energy expenditure, homeostasis, and appetite. The critical role of the MC4 pathway in weight regulation was validated with the discovery that single genetic defects along this pathway result in early-onset and severe obesity. A Phase 2 setmelanotide trial is ongoing for the treatment of Prader-Willi syndrome (PWS), a rare genetic disorder that causes life-threatening obesity. Recent scientific evidence implicates defects in the MC4 pathway as the likely cause of the weight and appetite abnormalities in PWS. A second Phase 2 trial is ongoing for the treatment of pro-opiomelanocortin (POMC) deficiency obesity, a very rare, life-threatening genetic disorder of the MC4 pathway associated with unrelenting appetite and obesity.

About FluidCrystal Injection Depot

The FluidCrystal Injection depot delivers therapeutic levels of drug substance over extended periods—tunable from days to months—from a single injection. While traditional depot therapeutics comprise complicated microsphere technology, Camurus’ depot offers a liquid solution that transforms into a controlled release liquid crystal gel matrix in situ on contact with minute quantities of aqueous fluid at site of injection. The FluidCrystal delivery system overcomes traditional side effects associated with high initial drug release on injection (drug burst) and poor drug stability by effectively encapsulating the drug compound in the nanopores of the depot matrix throughout the entire process from injection until final degradation. This, together with the ready-to-use product design, makes the system highly suitable for sustained parenteral delivery of peptides and proteins. FluidCrystal is a registered trademark of Camurus AB.
