In respect of [*], Santaris hereby grants to Miragen and its Affiliates a non-exclusive license, without right to sublicense, under the LNA Platform Technology and the Santaris Technology [*] (the “Non-Exclusive Research License,” and together with the Exclusive Research License, the “Research Licenses”). Miragen shall not have the right to grant any sublicenses under the Non-Exclusive Research License. At such time as Miragen no longer has any right to select any New Target [*] under Section 3.2, or to replace any New Target [*] under Section 2.3, the Non-Exclusive Research License shall become limited to the Targets comprising the six New Target [*] (including those New Target [*] that are replacements for prior New Target [*] but excluding the prior New Target [*] that have been replaced).

(b)

[*]

2.3.

Replacement Targets.

(a)

Subject to the procedure and limitations set forth in this Section 2.3, Miragen may replace each Miragen Target (and its Target [*]) at any time prior to: (i) in the case of an Existing Target [*] 1-3, the [*] anniversary of the Restatement Date and (ii) in the case of Existing Target Family 4 and each New Target [*], the [*] anniversary of the date such Target [*] was designated as the Existing Target [*] 4 pursuant to Section 2.1(a) or as a New Target [*] pursuant to Section 3.1, as applicable.

(b)

If Miragen desires to replace any Miragen Target, it shall notify Santaris and identify such Miragen Target (and its Target [*]) and provide the information described in Section 2.4(a) for the proposed replacement Target. The proposed replacement Target (and its Target [*]) [*]. If such proposed Target (and each member of its Target [*]) passes such gate-keeping procedure, then subject to compliance with subsection (d) below, it shall be designated as an Existing or New Target and its Target [*] shall be designated as an Existing or New Target [*], as the case may be, and this Agreement shall terminate with respect to the Target (and its Target

[*]) that has been replaced and the terms of Section 8.5(b) shall apply. If such proposed Target fails such gate-keeping procedure, then it shall not be designated as an Existing or New Target, as the case may be, and Miragen may propose alternative Target to replace such Miragen Target, subject to the same gate-keeping procedure until a proposed Target passes the gate-keeping procedure and is designated as an Existing or New Target; provided that each alternative proposal that is submitted after the applicable time period set forth in Section 2.3(a) shall be submitted within [*] days after the immediately prior proposal fails the gate-keeping procedure.

(c)

Miragen may replace each Miragen Target only [*], except that it may replace New Target [*] 1 [*].

(d)

Within [*] days after a proposed replacement Target passes the gate-keeping procedure, Miragen shall pay Santaris the amounts required under Section 4.3.

2.4.

Target Gate-keeping Procedure.

(a)

In respect of each Target that is subject to a gate-keeping procedure, including as provided in Sections 2.1(a), 2.3(b), 3.1(a) and 3.1(b), Miragen shall provide a notice of the proposed Target [*] (the “Target Notice”). In the Target Notice, Miragen will identify the proposed Targets comprising the Target [*] by the provision of the full length DNA sequence and [*] number.

(b)

Within [*] days after receipt of a Target Notice, Santaris shall either:

(i)

notify Miragen in writing that none of the Targets in the proposed Target [*] is an Excluded Target (as defined below), in which case the proposed Target shall be deemed to have passed the gate-keeping procedure; or

(ii)

notify Miragen in writing that the proposed Target [*] includes an Excluded Target, in which case Miragen shall have the right to verify such determination as set forth below.

If Santaris does not notify Miragen pursuant to Section 2.4(b)(i) or (ii) within such [*]-day period, then proposed Target shall be deemed to have passed the gate-keeping procedure.

(c)

If Santaris notifies Miragen in writing that the proposed Target [*] includes an Excluded Target, then upon Miragen’s request within [*] days thereafter, Santaris shall promptly submit to a mutually agreed independent Third Party auditor sufficient documentation for such Third Party auditor to verify that the proposed Target [*] includes an Excluded Target. Such Third Party auditor shall disclose to Miragen, within [*]

days of receiving such documentation from Santaris, only whether the proposed Target [*] includes an Excluded Target. The results of such verification procedure by such Third Party auditor shall be deemed the Confidential Information of Santaris. Miragen shall bear the costs of such Third Party auditor if such auditor finds that the proposed Target [*] includes an Excluded Target, and Santaris shall bear the costs of such Third Party auditor if such auditor finds that the proposed Target [*] does not include an Excluded Target. If such auditor finds that the proposed Target [*] does not include an Excluded Target or Miragen does not so request such verification, then the proposed Target [*] shall be deemed to have passed the gate-keeping procedure. If such auditor finds that the proposed Target [*] includes an Excluded Target, then the proposed Target [*] shall be deemed to have failed the gate-keeping procedure.

(d)

“Excluded Target” means a proposed Miragen Target (i.e., Existing Target [*] 4, New Target or replacement of an Existing or New Target) for which (i) prior to the date of Miragen’s nomination Santaris entered into an agreement with a Third Party that, at the time of Miragen’s nomination, prevents Santaris from granting an exclusive license to develop and commercialize LNA Compounds Targeting such Target as provided in Section 3.2; or (ii) prior to the date of Miragen’s nomination, Santaris has commenced a bona fide internal research and development program directed against such Target and the program is still ongoing at the time of Miragen’s nomination; or (iii) with respect to a Target other than [*], prior to the date of Miragen’s nomination, (A) Santaris has either (1) entered into an agreement with a Third Party that, when such agreement was in force, prevented Santaris from granting an exclusive license to develop and commercialize LNA Compounds Targeting such Target as provided in Section 3.2, but, at the time of Miragen’s nomination, such Third Party agreement has been terminated or otherwise no longer prevents Santaris from granting such an exclusive license, or (2) commenced a bona fide internal research and development program directed against such Target, but, at the time of Miragen’s nomination, the program has been suspended or halted, (B) a Patent claiming LNA Compounds Targeting such Target was filed by Santaris or its Third Party licensee and, at the time of Miragen’s nomination, (1) such Patent still includes at least one claim that claims one or more LNA Compounds Targeting such Target and (2) such Patent is still a pending patent application or is an issued and unexpired patent that has not been dedicated to the public, disclaimed, abandoned or held unenforceable or invalid by a court or other government authority of competent jurisdiction in an unappealed or unappealable decision, and (C) at least [*] have been completed [*] on such LNA Compounds by Santaris or its Third Party licensee.

(e)

If Miragen nominates as a Miragen Target any Target that is described in clause (iii) and not also described in clauses (i) or (ii) of subsection (d), Santaris shall notify Miragen of such status. If such nominated Target was previously the subject of an exclusive license granted by Santaris to a Third Party for such Third Party to develop and commercialize LNA Compounds Targeting such Target and at the time of Miragen’s nomination, such license agreement has been terminated and Santaris has payment obligations to such former exclusive licensee on account of the practice of Santaris Technology exclusively licensed to Santaris by such former exclusive licensee (such Santaris Technology, the “Reverted Technology”), then Santaris shall, within [*] days after receipt of the applicable Target Notice, disclose in writing to Miragen the scope and content of the Reverted Technology and Santaris’ payment obligations with respect to the practice of such Reverted Technology for the development and commercialization of LNA Compounds Targeting such Target. If Santaris then elects, in its discretion, to allow such nominated Target to be a Miragen Target, then the Parties shall negotiate in good faith to reach agreement on commercially reasonable terms and conditions to include such Target as a Miragen Target, including, if Miragen elects to obtain rights to the Reverted Technology, the obligation of Miragen to make all payments to such Third Party to obtain such rights. If the Parties have not reached such agreement within [*] days after Santaris notifies Miragen of its willingness to allow such nominated Target to be a Miragen Target, such nominated Target shall not become a Miragen Target.

2.5.

Research Diligence. In respect of each Exclusive Research License, Miragen shall use Diligent Efforts, either directly or, subject to the terms of Section 2.1, through one or more Sublicensees, to Discover and research Miragen Compounds and conduct pre-clinical development of one Product per Target [*] prior to IND Acceptance for a Product Targeting such Target [*] under such Exclusive Research License, including by maintaining and utilizing sufficient resources and facilities to perform such activities and using personnel with sufficient skills, experience and in such number as may be reasonably required to accomplish efficiently and expeditiously its objectives under such Exclusive Research License in good scientific manner and in compliance in all material respects with all applicable laws. Santaris’ sole remedy with respect to any breach of the diligence obligations set forth in this Section 2.5 shall be termination of the Exclusive Research License granted to Miragen with immediate effect with respect to the Existing Target for which Miragen has breached its diligence obligations set forth in this Section 2.5 in accordance with Section 8.2 and all other applicable effects of such termination set forth or referred to in Section 8.5. The Parties acknowledge and agree that Miragen has used Diligent Efforts in compliance with this Section 2.5 as of the Restatement Date.

2.6.

Joint Research Committee. Within 30 days following the Effective Date, Santaris and Miragen shall establish a joint research committee (the “JRC”) to assist Miragen’s efforts to research and Develop Products hereunder. The JRC shall serve primarily as a forum to facilitate communications between the Parties and enable Santaris to provide to Miragen such technical assistance and expertise as the Parties desire in the form of consultation and advice pursuant to Section 2.7

in connection with Miragen’s research and early development activities (including [*] and other similar activities) relating to the Miragen Compounds and Products. The JRC shall be comprised of two representatives from each Party as appointed by such Party. A Party may replace one or more of its representatives from time to time upon written notice to the other Party. Until the termination of this Agreement or December 18, 2015, whichever comes first, the JRC shall meet at least once each quarter at dates, times and locations mutually agreed by the JRC, unless the Parties mutually agree to a different meeting frequency. The JRC shall not have any authority to decide any matters arising hereunder on behalf of either Party.

2.7.

Technical Support. Santaris shall make its scientific personnel reasonably available to Miragen in connection with the meetings of the JRC or otherwise (including by telephone or email but not by any method that requires travel for such purpose) to:

(a)

[*]; and

(b)

[*]

Santaris shall not be required to provide any consultation or other services pursuant to this Section 2.7 after the earlier of (x) the [*] anniversary of the Restatement Date, and (y) the date on which a Miragen or Santaris Change of Control becomes effective; provided, that in the absence of a Miragen Change of Control, Santaris shall share with Miragen, during the Term of this Agreement, Know-How Controlled by Santaris that relates to toxicology or manufacture of, or obtaining Regulatory Approval for, LNA Compounds if Santaris identifies, in its sole discretion, such Know-How as useful to Miragen’s research, Development, [*] or Commercialization efforts pursuant to this Agreement. Notwithstanding anything otherwise to the contrary hereunder, Santaris shall not be required to perform any research or Development activities in connection with the Miragen Targets, Miragen Compounds or Products on behalf of Miragen, its Affiliates or Sublicensees or transfer to Miragen, its Affiliates or Sublicensees any materials in connection with the activities contemplated pursuant to this Section 2.7.

2.8.

Research Reports. Until the termination of this Agreement or Miragen’s provision of reports pursuant to Section 3.4 with respect to an Existing Target, whichever comes first, Miragen shall provide to the JRC, at least five business days in advance of each JRC meeting, a reasonably detailed written progress report on the status of its research activities with respect to each Existing Target for which the Exclusive Research License has not terminated, including summaries of data and results generated with respect to any such Targets and an assessment of the likelihood of, and timetable for, the completion of any applicable IND Enabling Studies and filing of any INDs with respect to such Targets. Each such report shall be deemed the Confidential Information of Miragen. For clarity, Miragen shall have no obligation to provide any report on its research activities conducted under its Non-Exclusive Research License.

2.9.

Miragen hereby acknowledges and agrees that, (a) it assumes sole responsibility for designating any Target, and (b) neither Santaris nor any of its Affiliates makes any representations or warranties [*]

3.	*PRODUCT DEVELOPMENT, [] COMMERCIALIZATION**.

3.1.

Product License Option. Miragen shall have the option to obtain a Product License for each New Target [*] as provided below (a “Product License Option”):

(a)

At [*] prior to commencing IND Enabling Studies of an LNA Compound Targeting any Target (other than an Existing Target), Miragen may exercise its right to obtain a Product License in respect of such Target (and members of its Target [*]) by written notice to Santaris and the Parties shall follow the gate-keeping procedure set forth in Section 2.4. Within [*] days after such proposed Target (and each member of its Target [*]) passes the gate-keeping procedure, Miragen shall pay the amount required under Section 4.5 and such Target and its Target [*] members shall then be a New Target and its Target [*] shall then be a New Target [*].

(b)

Within [*] days after the Effective Date, Miragen shall propose a Target (and members of its Target [*]) to be included in the Product License by written notice to Santaris and the Parties shall follow the gate-keeping procedure set forth in Section 2.4. If such proposed Target (and members of its Target [*]) passes such gate-keeping procedure, such Target and members of its Target [*] shall be designated as “New Target [*] 1”. If such proposed Target (or any member of its Target [*]) fails such gate-keeping procedure, Miragen shall have the right to propose alternative Targets until a proposed Target (and members of its Target [*]) passes the gate-keeping procedure and is thereby designated as New Target [*] 1.

(c)

There shall be no more than [*] New Target [*] at any particular time point. For clarity, if a New Target [*] is replaced under Section 2.3, such replaced Target [*] shall no longer be a New Target [*] and shall not be counted toward the total number of New Target [*]. Miragen shall not have the right to propose any New Target [*] (but excluding replacements for New Target [*], which may be proposed during the time period set forth in
Section 2.3(a)) after the [*] anniversary of the Restatement Date.

(d)

For clarity, Miragen’s Product License under Section 3.2 for New Targets will not cover any Target that is nominated by Miragen as a New Target but fails the gate-keeping procedure set forth in Section 2.4 or any other Target (other than an Existing Target) for which Miragen does not seek to nominate as a New Target (or any LNA Compounds Targeting any such Targets identified by the practice of the Non-Exclusive Research License).

(e)

Miragen acknowledges that nothing in this Agreement shall restrict Santaris, by itself and through its Affiliates and Third Parties, from discovering, researching, developing and commercializing LNA Compounds Targeting any Target that is not an Existing Target or a New Target. [*]

(f)

[*]

3.2.

Product License. Subject to the terms of Section 7.2(g), Santaris hereby grants to Miragen an exclusive license under the LNA Platform Technology and the Santaris Technology to research (other than to Discover), Develop, [*] and Commercialize Products in the Territory for use in the Field (the “Product License”). For clarity, the Product License for any Target that is subject to the gate-keeping procedure in Section 2.4 shall not become effective unless and until such Target has passed such gate-keeping procedure and Miragen pays the applicable amount (if any) under Section 4.5. Miragen may grant to its Affiliates or any Third Party a Sublicense under the Product License with the right to grant additional Sublicenses; provided, that each such Sublicense shall:

(a)

be a written agreement subject and subordinate to, and consistent with, the terms and conditions of this Agreement that are applicable to such Sublicense;

(b)

require each such Sublicensee to comply with all applicable terms of this Agreement, including keeping books and records with respect to sales of Products by such Sublicensee, permitting Santaris to audit (through an independent auditor and consistent with Section 4.12(b)) such books and records for the sole purpose of verifying Net Sales-based payments required to be paid by Miragen pursuant to Sections 4.9 and 4.10 and indemnifying Santaris in the same manner as provided in Section 9.1(a) with respect to activities performed by such Sublicensee; and

(c)

not in any way diminish, reduce or eliminate any of Miragen’s obligations under this Agreement, including any obligation to use Diligent Efforts to Develop or Commercialize any Product (but efforts of any Sublicensee in such regard shall be considered efforts of Miragen).

Miragen shall remain primarily responsible for its obligations hereunder and for the performance of its Sublicensees and shall guarantee that any such Sublicensees comply with all relevant provisions of this Agreement. Miragen shall provide Santaris a copy of each such sublicense agreement, which may be redacted of all confidential information not reasonably required for Santaris to verify that such agreement complies with this Section 3.2, provided that Miragen shall not redact the triggers for milestone or other payments under such sublicense agreement which will qualify as Upfront Payments or Sublicense Revenue upon receipt by Miragen, but may redact the amount of each such payment (which amount shall be disclosed to Santaris when Miragen receives such payment and is obligated to make a payment under Section 4.10 as a result of such receipt).

3.3.

Royalties. For the duration of the Royalty Period, on a Product-by-Product and country-by-country basis, Miragen shall pay to Santaris royalties equal to (a) [*] of Net Sales of such Product in such country by Miragen or its Affiliates and (b)

[*] (i) [*] of Net Sales of such Product in such country by Sublicensees or (ii) [*] of the Sublicense Royalties received by Miragen and its Affiliates on Net Sales of such Product in such country by Sublicensees, but not less than [*] of such Net Sales (except that, if Sublicense Royalties received by Miragen and its Affiliates on account of such Net Sales are, after deduction of Miragen’s Third Party payment obligations with respect thereto, less than [*] of such Net Sales, then [*] royalty shall be owed to Santaris with respect to such Net Sales); [*]. After the Royalty Period for any Product in any country in the Territory, no further royalties shall be payable in respect of sales of such Product in such country and thereafter the Product License with respect to such Product in such country shall be a fully paid-up, perpetual, irrevocable, royalty-free, exclusive license.

4.10.

Sharing of Upfront Payments and Sublicense Revenue. In respect of each Miragen Target for which a Product License is or becomes effective, Miragen shall pay Santaris (a) [*] of all Upfront Payments; and (b) subject to Section 4.7(c), [*] of Sublicense Revenue (for clarity, excluding any Sublicense Royalties) that, in each case, Miragen receives from a Sublicensee.

4.11.

Reports and Payments.

(a)

Royalty Statements and Payments. During the Royalty Period for a particular Product in a particular country, within [*] days after the end of each calendar quarter, Miragen shall deliver to Santaris a report setting forth for such calendar quarter the following information, on a Product-by-Product and country-by-country basis: (i) the Net Sales of such Product in such country during such calendar quarter, (ii) the basis for any adjustments to the royalty payable for such Net Sales of such Product in such country, (iii) the royalty due hereunder for the Net Sales of such Product in such country, (iv) the currency exchange rates used in determining such royalties and (v) the amount of Sublicense Revenue received by Miragen or its Affiliates for such Product in such country during such calendar quarter. No such reports shall be due for any Product until the First Commercial Sale of such Product in the Territory or Miragen has granted a Sublicense hereunder, whichever is earlier. The total royalty and share of Sublicense Revenue due for the sale of Products during such quarter shall be remitted at the time such report is made.

(b)

Taxes and Withholding. All payments under this Agreement shall be made in full without any deduction or withholding for or on account of any tax unless such deduction or withholding is required by applicable laws or regulations. If Miragen is so required to deduct or withhold, Miragen will (i) promptly notify Santaris of such requirement, (ii) pay to the relevant authorities the full amount required to be deducted or withheld promptly upon the earlier of determining that such deduction or withholding is required or receiving notice that such amount has been assessed against Santaris, and reduce the payment to Santaris by the same amount, (iii) promptly forward to Santaris an official receipt (or certified

copy) or other documentation reasonably acceptable to Santaris evidencing such payment to such authorities and (iv) cooperate reasonably, as Santaris may request (at Santaris’ expense), in efforts of Santaris to obtain a refund or otherwise recover such withheld taxes.

(c)

Currency. Except as expressly indicated otherwise, all amounts payable and calculations hereunder shall be in United States dollars. As applicable, Net Sales, Sublicense Revenues, Sublicense Royalties and any royalty deductions shall be converted into United States dollars in accordance with Miragen’s customary and usual conversion procedures, consistently applied.

(d)

Blocked Currency. If, at any time, legal restrictions prevent the prompt remittance of part or all royalties with respect to any country where any Product is sold, payment shall be made through such lawful means or methods as the Parties may mutually determine.

(e)

Interest on Late Payments. Any amounts not paid within [*] days after the date due under this Agreement are subject to interest from the date due through and including the date upon which payment is received. Such interest shall be calculated at a rate equal to [*] percentage points over the 90 day “London Interbank Offered Rate,” as such rate is published in The Wall Street Journal or successor thereto on the last business day of the applicable quarter prior to the date on which such payment is due, or the maximum rate permitted by law, whichever is less.

4.12.

Maintenance of Records; Audits.

(a)

Record Keeping. Miragen and its Affiliates shall keep, and shall cause its Sublicensees to keep, accurate books of account and records in connection with the sale of Products, in sufficient detail to permit accurate determination of all figures necessary for verification of all payments to be paid hereunder. Miragen, its Affiliates or Sublicensees shall maintain such records for a period of at least [*] years after the end of the year in which they were generated.

(b)

Audits. Upon [*] days prior written notice from Santaris, Miragen shall permit an independent certified public accounting firm of internationally recognized standing selected by Santaris and reasonably acceptable to Miragen, to examine, at Santaris’ sole expense, the relevant books and records of Miragen as may be reasonably necessary to verify the accuracy of the reports submitted by Miragen in accordance with Section 4.11(a) and the payment of royalties and the amounts payable under Section 4.10. An examination by Santaris under this Section 4.12(b) shall occur not more than [*] in any year and shall be limited to the pertinent books and records which have not previously been examined under this Section 4.12(b) by Santaris for any year ending not more than [*] years before the

date of the request. The accounting firm shall be provided access to such books and records at Miragen’s facilities where such books and records are normally kept and such examination shall be conducted during Miragen’s normal business hours. Miragen shall require its Sublicensees to grant Miragen, Santaris or an independent auditor approved by such Sublicensee and Santaris, to have comparable access to such Sublicensees’ relevant books and records to verify the payment of royalties. If a Party or an independent auditor engaged by a Party conducts an audit of a Sublicensee pursuant to the preceding sentence, such Party shall share the results of such audit, in confidence, with the other Party.

(c)

Underpayments/Overpayments. If such accounting firm concludes that additional royalties or share of Sublicense Revenue were due to Santaris, Miragen shall pay to Santaris the additional royalties within [*] days of the date Miragen receives such accountant’s written report so concluding. If such underpayment exceeds [*] of the royalties or share of Sublicense Revenue that were to be paid to Santaris, Miragen also shall reimburse Santaris for all reasonable charges of such accountants for conducting the audit. If such accounting firm concludes that Miragen overpaid royalties or share of Sublicense Revenue to Santaris, Miragen shall be entitled to reduce any subsequent payments by the amount of the overpayment.

5.	INTELLECTUAL PROPERTY.

5.1.

Ownership.

(a)

As between the Parties, Miragen shall be the sole and exclusive owner of all right, title and interest in and to all Miragen Compound Patents.

(b)

Subject to Section 5.1(a), as between the Parties, each Party shall own all inventions and other Know-How conceived, reduced to practice or otherwise made solely by employees of such Party and any Patents claiming such inventions.

(c)

Subject to Section 5.1(a), if any inventions or other Know-How are conceived, reduced to practice or otherwise made jointly by employees of both Parties in connection with any activities performed under this Agreement, such inventions and Know-How, and any Patents claiming such inventions (collectively, the “Joint IP”), shall be jointly owned by the Parties. Each Party may exploit any Joint IP without accounting to or obtaining consent from the other Party, subject to the rights and obligations of the Parties with respect to the Joint IP under this Agreement, including Miragen’s Research Licenses and Product Licenses and the rights granted Santaris under Section 8.5 (including Schedule 8.5(b)). The Parties shall discuss in good faith the terms and conditions upon which the prosecution, maintenance and enforcement of all Patents within the Joint IP shall be conducted and allocated between the Parties.

5.2.

Inventorship. All determinations of inventorship under this Agreement shall be made in accordance with the patent laws of the United States.

5.6.

[*] Patents.

(a) As of the Restatement Date, Santaris is conducting a bona fide internal program to develop LNA Compounds Targeting [*] (also referred to as “[*]”), and in connection with such program, Santaris is planning to assign the [*] Patents to an Affiliate that, at the time of such assignment, will be a wholly owned subsidiary of Santaris but that may subsequently become a Third Party as a result of investment by or sale to one or more Third Parties (such assignee of the [*] Patents, the “[*] Assignee”). Santaris hereby covenants to Miragen that, in connection with the assignment of the [*] Patents, Santaris shall obtain from the [*] Assignee and shall maintain during remainder of the Term after such assignment:

(i)

the exclusive license, with right to grant sublicenses, under the [*] Patents, to research, Develop, [*] and Commercialize LNA Compounds that are claimed by the [*] Patents and that are Targeting any Target other than [*] (the “[*] Targets”) in the Territory for use in the Field; and

(ii)

the right to cause the [*] Assignee, to the extent possible, practicable and not likely to have an adverse effect on the patentability, validity or enforceability of the [*] Patents, to file divisional patent applications to separate claims covering LNA Compounds Targeting [*] from claims that cover only LNA Compounds Targeting [*] Targets, and

(iii)

the right to cause the [*] Assignee to assign to Santaris any and all right, title and interest in and to each divisional patent application that does not claim LNA Compounds Targeting [*] and all Patents issuing from any such divisional patent application (collectively, the “[*] Divisional Patents”).

(b) Miragen shall not have any rights with respect to any [*] Patents, except as set forth in this Section 5.6(b) or Section 5.6(c) below. Santaris shall not, and shall ensure that its Affiliates, the [*] Assignee, and any future assignees or licensees of the [*] Patents shall not, assert against Miragen or its Affiliates, any of the [*] Patents that claim LNA Compounds Targeting [*] Targets, with respect to Miragen’s or its Affiliate’s discovery, identification, [*] for non-clinical research development, or performance of non-clinical research or pre-clinical development (up to immediately prior the commencement of IND Enabling Studies) of, LNA Compounds Targeting any such [*] Target, provided that such [*] Target passed the screening procedure set forth in Section 2.2(b). For clarity, the foregoing covenant not to xxx does not pertain to any LNA Compounds Targeting [*] because it is a Blocked Target and not capable of passing the screening procedure set forth in Section 2.2(b).

(c) In the event that Miragen nominates a [*] Target as a Miragen Target (whether as an Existing Target, New Target or a replacement for an Existing Target or New Target) for a Product License and such Target passes the gate-keeping procedure in Section 2.4 such that such [*] Target becomes a Miragen Target, then: [*]

6.	CONFIDENTIALITY.

6.1.

Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, the Parties agree that each Party (the “Receiving Party”) receiving any Confidential Information of the other Party (the “Disclosing Party”) shall keep such Confidential Information confidential and shall not publish or otherwise disclose or use such Confidential Information for any purpose other than to exercise it rights or perform its obligations under this Agreement, provided that such disclosure is (a) limited on a “need to know” basis to those persons directly involved in performing the relevant activities permitted under this Agreement who require access to such Confidential Information, and to legal representatives or (b) is subject to confidentiality obligations no less restrictive than those set forth herein.

6.2.

Confidential Information shall not include information that the Receiving Party can establish:

(a)

was already known by the Receiving Party (other than under an obligation of confidentiality) at the time of disclosure by the Disclosing Party and such Receiving Party has documentary evidence to that effect;

(b)

was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party;

(c)

became generally available to the public or otherwise part of the public domain after its disclosure to the Receiving Party and other than through any act or omission of the Receiving Party in breach of the confidentiality obligations set forth in this Article 6;

(d)

was disclosed to the Receiving Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the Disclosing Party not to disclose such information to others; or

(e)

was independently discovered or developed by or on behalf of the Receiving Party without the use of or reference to the Confidential Information of the other Party and the Receiving Party has documentary evidence to that effect.

6.3.

Authorized Disclosure and Use. Notwithstanding Section 6.2, the Receiving Party may disclose Confidential Information of the Disclosing Party to the extent such disclosure is reasonably necessary to:

(a)

file or prosecute patent applications which the Receiving Party is authorized to file or prosecute hereunder;

(b)

facilitate discussions with actual or potential collaborators, investors or acquirers in connection with a collaboration with, investment in or acquisition of the Receiving Party, subject to confidentiality obligations no less restrictive than those set forth herein (with shorter duration if appropriate but in no event for a period that is shorter than [*] years from the date of disclosure by the Receiving Party to such person or entity); or

(c)

to the extent necessary to comply with applicable laws or regulations of applicable governmental authorities, including in connection with filing, obtaining and maintaining Regulatory Approvals.

In the event that the Receiving Party shall deem it necessary to disclose pursuant to this Section 6.3 Confidential Information of the Disclosing Party, the Receiving Party shall to the extent possible give reasonable advance notice of such disclosure to the Disclosing Party and take reasonable measures to ensure confidential treatment of such information.

6.4.

SEC or Similar Filings. Either Party may disclose the terms of this Agreement to the extent required, in the reasonable opinion of such Party’s legal counsel, to comply with applicable laws, rules and regulations, including the rules and regulations promulgated by the United States Securities and Exchange Commission, the Copenhagen Stock Exchange or other applicable regulatory organizations or self-regulatory organizations. Notwithstanding the foregoing, before disclosing this Agreement or any of the terms hereof pursuant to this Section 6.4, the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure. If a Party discloses this Agreement or any of the terms hereof in accordance with this Section 6.4, such Party agrees, at its own expense, to seek confidential treatment of portions of this Agreement, or such terms, as may be reasonably requested by the other Party.

6.5.

Public Announcements; Publications.

(a)

Coordination. Santaris and Miragen shall, from time to time, and at the request of the other Party, discuss and agree on the general information content relating to this Agreement that may be publicly disclosed (including by means of any printed publication or oral presentation); provided, that Miragen, subject to Section 6.5(b) and Section 6.2, shall have no obligation to consult with Santaris with respect to any scientific publication or public announcement concerning its Development, Manufacturing or Commercialization activities with respect to Miragen Compounds and Products under this Agreement.

(b)

Announcements. Except as may be expressly permitted under Section 6.5(a) or as may be appropriate for Miragen to make in connection with its Development, [*] or Commercialization activities as contemplated hereunder, neither Party will make any public announcement regarding this Agreement or the Development, [*] or Commercialization of Miragen Compounds or Products without the prior written approval of the other Party. For the sake of clarity, nothing in this Agreement shall prevent Miragen from making any scientific publication or public announcement concerning its Development, [*] or Commercialization activities with respect to Miragen Compounds or Products under this Agreement; provided, that Miragen shall not disclose any Confidential Information of Santaris in any such publication or announcement without obtaining Santaris’ prior written consent to do so.

6.6.

Termination of Prior Confidentiality Agreement. This Agreement supersedes any confidentiality agreement(s) between the Parties dated prior to the Effective Date (collectively, the “Prior Confidentiality Agreements”), including any amendments thereto; provided, that the foregoing shall not limit any remedies available to either Party with respect to any breach of the Prior Confidentiality Agreements which occurred prior to the Effective Date. All Information (as defined in the Prior Confidentiality Agreements) exchanged between the Parties under the Prior Confidentiality Agreements shall be deemed to be Confidential Information under this Agreement and shall be subject to the terms of this Article 6.

7.	REPRESENTATIONS.

7.3.

Disclaimer. EXCEPT AS OTHERWISE EXPRESSLY SET FORTH HEREIN, THE PARTIES MAKE NO REPRESENTATIONS AND EXTEND NO WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, AND PARTICULARLY THAT THE USE OF ANY TARGET IS FREE OF ANY PATENT OR OTHER INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES, THAT PRODUCTS WILL BE SUCCESSFULLY DEVELOPED HEREUNDER, AND IF PRODUCTS ARE DEVELOPED, WITH RESPECT TO SUCH PRODUCTS, THE PARTIES DISCLAIM ALL IMPLIED WARRANTIES OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

8.	TERM AND TERMINATION.

8.1.

Term. The term of this Agreement will commence on the Effective Date and shall extend, unless this Agreement is terminated earlier in accordance with this Article 8, until (a) if there is at least one Miragen Target that has not been terminated, the expiration of all Royalty Periods, (b) the termination of the last Miragen Target (including all replacement Targets), provided that Miragen’s right pursuant to Section 3.1 to obtain a Product License for any New Target [*] expired prior to such termination, or (c) the expiration of Miragen’s right pursuant to Section 3.1 to obtain a Product License for any New Target [*], provided that all Miragen Targets (including their replacement Targets) were terminated before such expiration (the “Term”).

8.2.

Termination by Either Party for Material Breach by the Other Party.

(a)

Either Party may terminate this Agreement on a Target [*]-by-Target [*] basis at any time by giving written notice to the other Party if the other Party commits a material breach of its obligations under this Agreement with respect to a particular Target [*] and such breach remains uncured for [*] days (or [*] days in the case of the breach of a payment obligation) from the date written notice of such breach (which notice shall identify the relevant Target [*]) is given to the breaching Party. Additionally, if Miragen fails to cure any deemed material breach under the penultimate sentence of Section 3.1(f) within the cure period referred to therein, Santaris may terminate this Agreement with respect to one or more Miragen Targets upon written notice to Miragen and without any additional cure periods.

(b)

Either Party may terminate this Agreement in its entirety at any time by giving written notice to the other Party if the other Party commits a material breach of its obligations under this Agreement that are not directed only to a particular Target [*] and such breach remains uncured for [*] days (or [*] days in the case of the breach of a payment obligation) from the date written notice of such breach is given to the breaching Party.

(c)

Each Party may terminate this Agreement with immediate effect upon providing the other Party with written notice if the other Party breaches Section 11.1(a).

(d)

[*]

8.3.

Termination on Insolvency. This Agreement may be terminated in its entirety with immediate effect by Santaris upon written notice to Miragen if (a) a case is commenced by or against Miragen under applicable bankruptcy, insolvency or similar laws and not dismissed within [*] days thereafter, (b) Miragen files for or is subject to the institution of bankruptcy, reorganization, liquidation, receivership or similar proceedings that are not dismissed within [*] days thereafter, (c) Miragen assigns all or a substantial portion of its assets for the benefit of creditors, (d) a receiver or custodian is appointed for Miragen’s business and is not dismissed within [*] days after appointment, (e) a substantial portion of Miragen’s business is subject to attachment or similar process, which attachment or similar process is not dismissed within [*] days thereafter, (f) Miragen suspends making payments with respect to all or any class of its debts for a period of more than [*] days or (g) anything analogous to any of the events described in the foregoing subsections (a) through (f) occurs under the laws of any applicable jurisdiction and is not addressed or corrected within [*] days.

8.5.

Effects of Termination.

(a)

Effect of Termination by Miragen for Material Breach by Santaris. If Miragen terminates this Agreement with respect to any or all Target [*] pursuant to Section 8.2, then all rights and obligations of each Party under this Agreement shall terminate with respect to such Target [*] (or the Agreement in its entirety as the case may be), subject to Section 8.7.

(b)

Effect of Termination for Targets Terminated by Miragen At Will, Replaced by Miragen, or Terminated by Santaris for Miragen’s Material Breach or Insolvency. If:

(i)

Miragen gives notice of termination of one or more Miragen Target(s) (and its Target [*]) pursuant to Section 8.4,

(ii)

Miragen replaces one or more Miragen Target(s) (and its Target [*]) pursuant to Section 2.3, or

(iii)

Santaris terminates one or more Miragen Target(s) (and its Target [*]) pursuant to Sections 3.1(f), 8.2 or 8.3

then, in each case, upon the effective date of such termination, the provisions in Schedule 8.5(b) shall apply.

(c)

Santaris agrees that, if this Agreement is terminated by Santaris pursuant to Section 8.2 or 8.3 and such termination did not arise directly or indirectly from any acts or omissions of a particular Sublicensee, Santaris will, at such Sublicensee’s request, enter into an agreement (the “Direct License”) with such Sublicensee whereby such Sublicensee would receive:

(i)

with respect to the rights granted by Santaris to Miragen under this Agreement and sublicensed to such Sublicensee by Miragen under a Sublicense, as a substitute for its Sublicense from Miragen (which Sublicense was terminated as a result of the termination of this Agreement), a direct license from Santaris of the same scope as such Sublicense; and

(ii)

with respect to rights licensed to Santaris from or by Miragen pursuant to Schedule 8.5(b) upon such termination, a direct sublicense from Santaris of the same scope as such Sublicensee’s licenses with respect thereto under its Sublicense with Miragen, and such Sublicensee would retain, with respect thereto, the patent prosecution and enforcement rights set forth in its Sublicense with Miragen.

If such Sublicensee requests a Direct License from Santaris, such Sublicensee shall not be required as a result of such termination of this Agreement with respect to Miragen to grant Santaris the licenses set forth in Schedule 8.5(b) in respect of any Miragen Compound Patents or Miragen Product Technology Controlled by such Sublicensee. The Direct License shall be on the same terms and conditions that applied to Miragen under this Agreement, including terms with respect to termination and the effects thereof; provided, that Santaris shall receive from such Sublicensee the same financial payments that Santaris would have otherwise received from Miragen under Sections 4.9(b) and 4.10 of this Agreement if this Agreement had not been terminated with respect to Miragen and such Sublicensee had remained a Sublicensee. For clarity, the Direct License shall not require such Sublicensee to pay Santaris the amounts that Miragen would have been required to pay to Santaris pursuant to Section 4.7 or 4.9(a). [*]

(d)

[*]

(e)

Effect of Termination of the Non-Exclusive Research License. If this Agreement is terminated in its entirety for any reason before expiration of the Non-Exclusive Research License, the Non-Exclusive Research License shall terminate, in addition to any other effects under this Section 8.5.

8.6.

Pending Dispute Resolution. If a Party gives notice of termination under Section 8.2 and the other Party disputes whether such notice was proper, then the issue of whether this Agreement has been terminated (in its entirety or with respect to only one or more Target [*]) shall be resolved in accordance with Article 10, and each Party shall continue to perform its obligations hereunder pending the conclusion of such dispute resolution proceeding. If as a result of such dispute resolution process it is determined that the notice of termination was proper, then such termination shall become effective if the breach is not cured within [*] or [*] days, as applicable, of such determination. Subject to Section 9.5, a breaching Party shall remain liable for any damages accrued during any dispute resolution proceeding described in this Section 8.6. If as a result of such dispute resolution proceeding, it is determined that the notice of termination was improper, then no termination shall have occurred and this Agreement shall remain in effect.

8.7.

Survival of Certain Obligations. Expiration or termination of this Agreement shall not relieve either Party of any obligation (including payment obligations) that accrued before the effective date of such expiration or termination. Nothing in Section 3.1(f) or this Article 8 shall be deemed to limit a Party from any other remedy that such Party may have for a material breach of this Agreement by the other Party. The rights and obligations of the Parties with respect to any Target [*] not terminated hereunder shall remain in full force and effect for the remainder of the Term. The following provisions shall survive expiration or termination of this Agreement: Sections 2.2(b)(vi), 3.1(f), 3.6 (last sentence only and solely in respect of activities conducted or Product sold prior to termination), 4.9 (last sentence and solely with respect to Royalty Periods that have expired prior to the termination of this Agreement and to the expiration of the Agreement), 4.11 (solely in respect of royalties and other amounts accrued hereunder prior to termination), 4.12, 5.1, 5.2, 5.3(b), 7.3, 8.5 (including Schedule 8.5(b)) and 8.7, and Articles 1, 6 (provided that Section 6.5(b) shall survive solely with respect to the announcement of the termination or expiration of this Agreement), 9, 10 and 11.

except, in each case, to the extent caused by (i) the gross negligence or willful misconduct of Miragen or any Miragen Indemnified Party, (ii) any Miragen representation set forth herein being untrue when made or (iii) any breach by Miragen of any of its covenants under this Agreement.

9.3.

Procedure. Each Party will notify the other promptly in the event it becomes aware of a claim for which indemnification may be sought hereunder. In furtherance and not in limitation of the preceding sentence, in case any proceeding (including any governmental investigation) shall be instituted involving any Party in respect of which indemnity may be sought pursuant to this Article 9, such Party (the “Indemnified Party”) shall promptly notify the other Party (the “Indemnifying Party”) in writing within [*] days after the Indemnified Party first becomes aware of such proceeding and the Parties shall promptly meet

to discuss how to respond to any claims that are the subject matter of such proceeding. The Indemnifying Party shall have the right to assume the defense of any claim asserted by a Third Party subject to indemnification obligations hereunder. The Indemnifying Party, upon assuming the defense of such claim, shall retain counsel reasonably satisfactory to the Indemnified Party to conduct the defense of such claim and shall pay the fees and expenses of such counsel. The Indemnified Party shall cooperate fully with the Indemnifying Party in the defense of any such claim or proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both such parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any loss or liability by reason of such settlement or judgment. The Indemnifying Party shall not, without the written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which the Indemnified Party is, or arising out of the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on claims that are the subject matter of such proceeding.

9.4.

Insurance. Miragen shall obtain and maintain commercial general liability insurance with reputable and financially secure insurance carriers to cover its indemnification obligations under Section 9.1, with limits of not less than [*] per occurrence and in the aggregate, or after Miragen’s commencement of a human clinical trial with limits of not less than [*] per occurrence and in the aggregate. Such insurance shall be procured with carriers having an A.M. Best Rating of A-VII or better.

9.5.

Liability. Except with respect to liability arising from a breach of Article 6, or to the extent such Party may be required to indemnify the other Party under this Article 9, NEITHER PARTY NOR ITS RESPECTIVE AFFILIATES SHALL BE LIABLE TO THE OTHER PARTY FOR SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES, WHETHER BASED ON CONTRACT OR TORT, OR ARISING UNDER APPLICABLE LAW OR OTHERWISE, IN CONNECTION WITH THIS AGREEMENT.

10.

DISPUTE RESOLUTION.

10.1.

Executive Mediation. The Parties shall first seek to resolve any controversy, claim or dispute arising out of or relating to this Agreement through good faith discussions. If the Parties are unable to resolve such dispute in the course of such discussions, the matter shall be referred to the Parties’ respective Executive

Officers to be resolved by negotiation in good faith as soon as is practicable but in no event later than [*] days after referral. If the Executive Officers cannot resolve such dispute within such [*]-day period, either Party may initiate the dispute resolution procedures set forth in Section 10.2. Any discussions or negotiations between the Parties pursuant to this Section 10.1 shall not be admissible in any subsequent dispute resolution proceeding. For purposes of this Article 10, “Executive Officers” means the President of Miragen (or an executive officer of Miragen designated by such President of Miragen) and the Chief Executive Officer of Santaris (or an executive officer of Santaris designated by such Chief Executive Officer of Santaris). For the avoidance of doubt, no controversy, claim or dispute arising out of or relating to this Agreement may be referred to binding arbitration under Section 10.2 until the Parties have followed the executive mediation procedure set forth in this Section 10.1; provided, however, neither Party shall be required to follow the executive mediation procedure set forth in this Section 10.1 before attempting to obtain a temporary restraining order, preliminary injunction or other interim or conservatory relief.

10.2.

Arbitration.

(a)

If a dispute is not resolved by the negotiation of the Executive Officers as set forth in Section 10.1, the Parties agree to resolve such dispute through final and binding arbitration conducted under [*]. At any time following the [*]-day period of negotiation between the Executive Officers set forth in Section 10.1, either Party may initiate arbitration of an unresolved dispute by written notice to the other Party of its intention to arbitrate, which notice shall specify in reasonable detail the nature of the dispute.

(b)

The arbitration shall be conducted by a panel of three persons; provided, that if the dispute involves claims for damages of less than [*], there shall be only one arbitrator, nominated jointly by the Parties within [*] days of such arbitration notice. Within [*] days after the initiation of arbitration, each Party shall nominate one person to act as arbitrator and the two Party-selected arbitrators shall jointly nominate a third arbitrator within [*] days of their appointment. If any arbitrator is not nominated within these time periods or any arbitrator so nominated by the Parties under this Section 10.2 is not approved by the [*] for appointment, the [*] shall appoint a suitable replacement. Arbitrators shall be independent experts (including lawyers) with at least ten years experience with intellectual property licensing agreements in the pharmaceutical industry and shall not be or have been an Affiliate, sublicensee, employee, consultant, officer, director or stockholder of either Party, and shall comply with the requirements of the IBA Guidelines on Conflicts of Interest in International Arbitration. The chair of the tribunal shall not have the same nationality of either Party.

(c)

The arbitration proceedings shall be conducted [*]. The arbitration proceedings and all pleadings and written evidence shall be in the English language. Any written evidence originally in another language shall be submitted in English translation accompanied by the original or a true copy thereof.

(d)

Each Party agrees to use reasonable efforts to make all of its current employees available to testify or provide written statements, if reasonably necessary. In addition to the authority conferred upon the arbitral tribunal by the Rules, the arbitral tribunal shall have the authority to order production of documents in accordance with the IBA Rules on the Taking of Evidence in International Arbitration.

(e)

The arbitrators shall have the power to decide all questions of arbitrability. The arbitrators shall be instructed and required to render (A) a draft resolution or award within [*] days of the conclusion of the taking of evidence, and the Parties may provide comments thereon within ten days after its receipt and (B) a final written resolution and award on each issue that clearly states the basis upon which such resolution and award is made. The final written resolution and award shall be delivered to the Parties as expeditiously as possible, but in no event more than [*] days after conclusion of the taking of evidence.

(f)

Confirmation of, or judgment upon, any award rendered by the tribunal may be entered in any competent court or application may be made to any competent court for judicial acceptance of such an award and order for enforcement. Each Party agrees that, notwithstanding any provision of applicable laws or of this Agreement, it shall not request, and the arbitrators shall have no authority to award, punitive or exemplary damages against any Party. The Parties may apply to any court of competent jurisdiction for a temporary restraining order, preliminary injunction or other interim or conservatory relief, as necessary, without breaching these arbitration provisions and without abridging the powers of the arbitrators.

(g)

Except to the extent necessary to confirm or obtain judgment on an award or decision or as may be required by applicable laws, neither Party may, and the Parties shall instruct the arbitrators not to, disclose the existence, content, or results of an arbitration without the prior written consent of both Parties.

(h)

The Parties agree that (i) [*] (ii) [*]. Any payment to be made by a Party pursuant to a decision of the tribunal shall be made in United States dollars, without any deductions made for tax obligations or any other deductions.

11.

MISCELLANEOUS.

Assignment; Change of Control.

(a)

Assignment. Neither this Agreement nor any interest hereunder shall be assignable, nor any obligation hereunder shall be delegated, by either Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed; provided, that Santaris shall have the right to assign its right to receive cash payments under Article 4 to a Third Party upon prior written notice to Miragen. Notwithstanding the foregoing and subject to subsections (b) and (c) below, each Party may, without the other Party’s consent, assign its entire interest in this Agreement to (i) an Affiliate of such assigning Party for so long as such person or entity remains an Affiliate of such assigning Party or (ii) a successor to all or substantially all of its assets, whether by acquisition, merger, sale of stock, sale of assets or other transaction; provided that, in the case of assignment to its Affiliate, the assigning Party shall guarantee the performance of this Agreement by such Affiliate. This Agreement shall be binding upon the successors and permitted assigns of the Parties. Any assignment not in accordance with this Section 11.1 shall be void.

(b)

Miragen Change of Control. Upon a Miragen Change of Control, the milestone payments referred to in items (i) and (ii) in the table set forth in Section 4.7(a) that have not been achieved by Miragen or its Affiliates before such Miragen Change of Control shall be increased by [*] of the amounts set forth in such sections.

The waiver by either of the Parties of any breach of any provision hereof by the other Party shall not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself.

11.8.

Severability. If any provision of this Agreement is held to be invalid or unenforceable by a court of competent jurisdiction from which no appeal can be or is taken, such provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof.

11.12.

Nothing herein contained shall be deemed to create an employment, agency, joint venture or partnership relationship between the Parties or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party shall have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.
