(a) Dicerna may grant written sublicenses (each, a “Sublicense Agreement”) to the Licensed Intellectual Property (subject to Section 2.4(b)) solely to Develop, Manufacture and Commercialize Products are solely directed to the treatment of PH1 for use in the Field, including to CMOs; provided, however, that any sublicense granted by Dicerna shall be subject and, except as set forth below, subordinate to the terms and conditions of this Agreement and shall contain terms and conditions consistent with those in this Agreement. Dicerna shall assume full responsibility for the performance of all obligations and observance of all terms herein under the licenses granted to it. If Dicerna becomes aware of a material breach of any Sublicense Agreement by a Sublicensee, Dicerna shall promptly notify Protiva of the particulars of same and take Commercially Reasonable Efforts to enforce the terms of such Sublicense Agreement. All Sublicense Agreements shall provide that the Sublicensee may only use the Confidential Information of Protiva in accordance with terms of this Agreement applicable to Dicerna’s use of such Confidential Information and subject to provisions at least as stringent as those set forth in Article VI. Dicerna shall use Commercially Reasonable Efforts to make Protiva an express third-party beneficiary of each CMO Agreement (as defined in the Supply Agreement), and Protiva shall be an express third-party beneficiary of any other Sublicense Agreement, including the provisions related to use and disclosure of Protiva’s Confidential Information.

(a) Each of Protiva and Tekmira expressly retains any rights not expressly granted to Dicerna under this Article II (or otherwise under this Agreement) or under the Supply Agreement. Nothing in Section 2.1 limits Protiva’s ability to perform its obligations under this Agreement or the Supply Agreement.

(b) Notwithstanding anything to the contrary contained herein but subject to terms set forth in the Supply Agreement, including Section 7.2 of the Supply Agreement, (i) neither Tekmira nor Protiva is granting to Dicerna a license to Research, Develop or otherwise improve upon the Lipid Nanoparticles based on Tekmira Patents or Protiva Intellectual Property or Confidential Information it has received from Tekmira or Protiva (but, for clarity, Dicerna may otherwise Research, Develop and improve upon Lipid Nanoparticles without the use of Tekmira Patents, Protiva Intellectual Property or Confidential Information it has received from Tekmira or Protiva); and (ii) no license is provided from either Party to the other to use its Know-How, except as may be necessary or useful for a Party to fulfill its obligations to any Regulatory Authority (subject to the penultimate sentence in Section 6.3) or necessary for a Party to perform the activities required or expressly permitted under this Agreement, the Supply Agreement or the Quality Agreement and with respect to the Product.

ARTICLE III –FINANCIAL PROVISIONS

3.1 Upfront Payment and Milestone Payments.

(b) Subject to the terms and conditions of this Agreement, Dicerna shall make the following fully-earned, non-refundable and non-creditable milestone payments upon the achievement of the specified milestones with respect to a Product (each a “Milestone Payment”):

Milestone Event	Milestone Fee

[***]	[***]
[***]	[***]

(c) If there is more than one Product in Development or Commercialization at the same time, Dicerna shall be obligated to make each Milestone Payment for every Product that achieves the milestone set forth above (i.e., if there is more than one Product that satisfies the applicable milestone event, more than one Milestone Payment for the milestone event shall be owed by Dicerna to Protiva); provided, however, that if the first milestone event in Section 3.1(b) has been reached for a Product (i.e., initiation of a first Pivotal Trial) and the Milestone Payment made, but such Product does not ultimately obtain Regulatory Approval in the United States, any EU market or the market of any EU member state, then on any subsequent Product there will not by any Milestone Payment due upon the initiation of a first Pivotal Trial for that subsequent Product.

(d) Dicerna shall act in good faith in determining whether to designate its clinical trials for Products as “pivotal trials” and shall not manipulate the structure of its clinical trials for Products that would otherwise meet the definition of a Pivotal Trial in such a manner as to avoid meeting such definition for purposes of delaying payment of the applicable Milestone Payment.

3.2 Royalty Payments.

(a) In addition to the payments set forth in Section 3.1, during the Royalty Payment Term, Dicerna shall pay to Protiva the following royalty amounts with respect to the Net Sales of Products (the “Royalty”):

Royalty Table

For all cumulative, worldwide Net Sales less than [***]	[***]
For cumulative, worldwide Net Sales equal to or exceeding [*] but less than [*]	[***]
For cumulative, worldwide Net Sales equal to or exceeding [***]	[***]

(b) For clarity, the application of the Royalty tiers in the above Royalty Table will be progressive, meaning that the Royalty percentage in each tier only applies to Net Sales in that tier and not retroactively to prior Net Sales in a lower tier.

(c) No royalty offsets shall apply for Third Parties owed royalties by Dicerna for DCR-PH1 or any adjuvant or additional active substance. The Royalties are inclusive of royalties, if any, owed by Protiva to Third Parties for any intellectual property licensed to Dicerna under this Agreement, which third-party royalties are exclusively the obligation of Protiva.

3.3 Royalty Reports; Expense Reports; Records and Audits.

(a) Within [***] after the end of each calendar quarter during the Royalty Payment Term until the calendar quarter after which Dicerna or any of its Affiliates or Sublicensees is no longer selling any Products, Dicerna shall provide to Protiva a written report (in electronic form) that includes, for each calendar quarter, (i) the gross invoiced sales of the Product sold during such quarter, (ii) the Net Sales of the Products, and (ii) the calculated amount of the Royalty owed by Dicerna pursuant to Section 3.2 in respect of the sale of the Products. If reasonably requested by Protiva, Dicerna will also provide non-binding estimates for Net Sales and Royalties after the calendar quarter end but prior to delivery of the written report.

(b) Until the fifth (5th) anniversary of the date any book or record is created or such longer period required by Applicable Law (the “Record Retention Period”), Dicerna shall maintain and retain complete and accurate books of account and records covering all transactions relating to payment of amounts that may be due under Section 3.2 of this Agreement. Upon the reasonable advance notice of Protiva (of at least [***]), Dicerna shall make such books and records available for inspection and audit by Protiva’s authorized representative (which shall be a national certified public accounting firm designated by Protiva), subject to reasonable precautions to protect the confidential information of Dicerna. Protiva may not audit Dicerna’s books and records more than once in any [***]. All audits must be conducted during normal business hours of Dicerna and conducted in a manner so as to minimize the impact on the normal operations of Dicerna. The accounting firm conducting any such audit must provide a report of its findings of any audit to both Parties, may only identify in such report whether the amount of Royalties paid was correct and the actual amount of Royalties payable and may not disclose any other Confidential Information of Dicerna. The auditor’s report and all other information disclosed to the auditor or generated by the auditor in such audit will be the Confidential Information of Dicerna. Protiva shall pay the cost of such audits unless it discovers that Dicerna has underreported aggregate Net Sales during any year in the Record Retention Period by an amount of [***] or more, in which case the costs of such audit shall be borne by Dicerna. If an audit reveals an underpayment or overpayment, the Party responsible for making payment shall promptly pay to the other Party the amount of the underpayment or overpayment discovered unpaid under this Section 3.3(b), subject to Section 3.4(d).

3.4 Payment Procedure.

(a) Remittance of payments under this Article III shall be made by means of wire transfer of immediately available funds to a bank account designated in advance in writing by Protiva. All amounts payable to Protiva under this Agreement shall be paid in United States Dollars. In those cases in which the amounts due in United States Dollars is calculated based on one or more currencies other than United States Dollars, such amounts shall be converted into United States Dollars using the spot exchange rate for the relevant currency on the date of the applicable transaction, as such exchange rate is published by the Wall Street Journal (or comparable publication if not available).

(b) Any Milestone Payment owed pursuant to Section 3.1(b) shall be paid by Dicerna to Protiva within [***] after the occurrence of the event triggering the payment of such Milestone Payment.

(c) Any Royalty shall accrue in accordance with Section 3.2 during the applicable Royalty Payment Term. Royalty obligations that accrue during a calendar quarter shall be paid within [***] after the end of such quarter.

(d) Any payments due from one Party to the other Party under this Article III that are not paid by the date such payments are due shall bear interest from the date such unpaid payments are due until paid in full at the lesser of: (i) [***] per month; or (ii) the highest amount of interest permitted by Applicable Law. The foregoing interest shall be in addition to any other remedies that either Party may have pursuant to this Agreement.

(e) Protiva is solely responsible for any sales, use, excise, value-added, services, consumption, or other similar tax that is assessed in connection with any payment due hereunder and shall either pay such payment directly or reimburse Dicerna for the same. Any withholding or other taxes that Dicerna or its Affiliates are required by Applicable Law to withhold or pay on behalf of Protiva may be deducted from such payments and paid to the appropriate tax authority contemporaneously with the remittance to Protiva, provided that (i) Dicerna promptly furnishes to Protiva proper evidence of the taxes so paid and (ii) Dicerna cooperates with and furnishes to Protiva appropriate documents to secure application of the most favorable rate of withholding tax under Applicable Law (or exemption from such withholding tax payments, as applicable). Dicerna and Protiva shall use Commercially Reasonable Efforts to cooperate to minimize any such taxes, assessments and fees to the extent permitted by Applicable Law.

3.5 Term of Payments. Following expiry of the Royalty Payment Term in respect of any country (a) the licenses granted to Dicerna with respect to such country become fully paid-up, sublicensable, royalty-free, exclusive (subject to Section 2.1(b)), transferable, perpetual and irrevocable licenses continuing indefinitely and (b) the obligation of Dicerna to pay any Royalties with respect to sales of Products in such country terminates.

ARTICLE IV –ADDITIONAL OBLIGATIONS

4.1 Obligations of Protiva. Protiva shall, itself or through its Affiliates or Permitted Contractors upon Dicerna’s reasonable request, use Commercially Reasonable Efforts to assist Dicerna in obtaining any license from any Third Party needed for Dicerna or its Affiliates to exploit the LNP Technology as contemplated by this Agreement (provided that such efforts would not require Protiva to make any payment to any such Third Party).

4.2 Obligations of Dicerna.

(a) Dicerna shall, itself or through its Affiliates or Sublicensees, use Commercially Reasonable Efforts to Develop and Commercialize the Product, provided that Protiva’s sole remedy for Dicerna’s breach of this Section 4.2(a) is as set forth in Section 8.3.

The foregoing does not prohibit Dicerna from licensing any Third Party technology or intellectual property necessary to Develop, Manufacture, or Commercialize the Products.

4.3 Other Obligations and Agreements of the Parties.

(a) Each Party agrees that from the Effective Date until the expiration of one (1) year after the expiration of the Term of this Agreement, it shall not, except upon the express prior written consent of the other Party in each instance, directly or indirectly employ in any capacity (whether as a full or part time employee or as a consultant or contractor) any individual who is then employed by such other Party and has worked in any capacity related to this Agreement, the Supply Agreement or the Quality Agreement.

Protiva shall: (A) notify Dicerna promptly after initiating any such PH1 Patent Infringement Action and (B) consult closely with Dicerna regarding all aspects of such PH1 Patent Infringement Action and permit Dicerna to have an attorney of its own choosing participate in such PH1 Patent Infringement Action.

If the non-Enforcing Party is requested to join as a party to a PH1 Patent Infringement Action it may be represented, at the cost of the Enforcing Party, by counsel mutually agreed by the Parties.

(ii) The Parties shall share in the proceeds from any PH1 Patent Infringement Action under this Section 5.3(c), including settlements thereof (the “Proceeds”), as follows:

(a) First, for the costs and expenses, including legal fees, that are incurred by the Enforcing Party as part of or in preparation of the PH1 Patent Infringement Action, including the costs and expenses of the non-Enforcing Party reimbursed by the Enforcing Party in accordance with this Section (the “Enforcement Costs”); and

(d) With respect to any infringement or suspected infringements of any of the Protiva Patents or Tekmira Patents that would result in action that could reasonably be considered both an PH1 Patent Infringement Action and a Non-PH1 Patent Infringement Action, Protiva shall have the first right to initiate an infringement or other appropriate suit, subject to Section 5.3(c). If Protiva elects not to initiate, pursue or maintain any such Patent Infringement Action, Protiva shall provide Dicerna with prompt written notice of the same and, thereafter, Dicerna will have the right, but not the obligation, to initiate, pursue or maintain only the claims that would form the basis of an PH1 Patent Infringement Action, all at Dicerna’s sole cost and expense, subject to Section 5.3(c).

ARTICLE VI –CONFIDENTIAL INFORMATION AND PUBLICITY

6.1 Limitation of Disclosure. With the exception of information essential for Regulatory Authority filings and documentation not fulfilled by use of the DMF, neither Party shall be obligated to disclose to the other Party confidential information related to its technology. Protiva shall disclose specific information regarding the chemical composition of a formulation in Lipid Nanoparticles used in the Product for purposes of filings with the Regulatory Authorities; provided, however, that (i) Protiva shall not be obligated to disclose to Dicerna the details related to any process in which such formulation was selected, nor the chemistry of any other lipids not used in the formulation and (ii) subject to Section 6.3, if Protiva discloses Confidential Information to Dicerna for use with Regulatory Authorities, Dicerna shall not disclose such Confidential Information without Protiva’s prior written consent.

6.2 Non-Disclosure of Confidential Information. Each Party agrees that, for itself and its Affiliates, until the tenth (10th) anniversary of the termination or expiration of this Agreement, a Receiving Party shall maintain all Confidential Information of the Disclosing Party in strict confidence and shall not (a) disclose Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below and to the Receiving Party’s and its Affiliates’ Sublicensees and each of their employees who have a need to know such Confidential Information for purposes of exploiting the licenses granted herein or otherwise conducting their activities under this Agreement or (b) use Confidential Information for any purpose except those explicitly licensed or otherwise authorized or permitted by this Agreement; provided that the foregoing obligations shall survive with respect to any Confidential Information that is receiving protection as a trade secret under Applicable Law for so long as such Confidential Information continues to receive such protection.

6.3 Exceptions. The obligations in this Article VI shall not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent documented proof: (i) was known to the Receiving Party or its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party; (ii) is subsequently disclosed to the Receiving Party or its Affiliates by a Third Party lawfully in possession thereof and without any obligation to keep it confidential or any restriction on its use; (iii) is or otherwise becomes generally available to the public or enters the public domain, either before or after it is disclosed to the Receiving Party and such public availability is not the result, directly or indirectly, of any fault of, or improper taking, use or disclosure by, the Receiving Party or its Affiliates or anyone working in concert or participation with the Receiving Party or its Affiliates; or (iv) has been independently developed by employees or contractors of the Receiving Party or its Affiliates without the aid, application or use of Confidential Information of the Disclosing Party. Notwithstanding the foregoing, (A) specific Confidential Information disclosed by a Disclosing Party shall not be deemed to be within any exceptions set forth in (i), (ii), or (iii) above merely because it is embraced by more general information to which one or more of those exceptions may apply, (B) no combination of information shall be deemed to be within any such exceptions unless the combination itself and its principle of operation are within the public domain and (C) disclosure of Confidential Information to Regulatory Authorities shall not constitute a public disclosure (i.e., it shall remain Confidential Information after such disclosure). Even though Confidential Information may be within one of the exceptions described in the preceding sentence, the Receiving Party shall not disclose to Third Parties that the excepted Confidential Information was received from the Disclosing Party.

6.4 Permitted Uses; Protection. Confidential Information of a Disclosing Party may be used by the Receiving Party in the performance of its obligations under this Agreement, the Supply Agreement and the Quality Agreement, including disclosures to Permitted Contractors who are bound by enforceable confidentiality agreements with terms consistent with and at least as protective as this Article VI, as otherwise expressly authorized in this Agreement or as expressly authorized by the Disclosing Party in writing. Confidential Information that is Licensed Intellectual Property may be used by Dicerna subject to and in accordance with the provisions of this Agreement, the Supply Agreement and the Quality Agreement, to the extent applicable to Dicerna’s license to Licensed Intellectual Property. Each Receiving Party shall take steps to maintain the confidentiality of the Disclosing Party’s Confidential Information that are consistent with the steps it takes to maintain the confidentiality of its own confidential information of a similar value, but in no event less than commercially reasonable steps; provided, however, that nothing in this Agreement shall be deemed to eliminate, restrict, or otherwise limit Dicerna’s license to use such Confidential Information in accordance with the terms and conditions of this Agreement, even if such use may result, directly or indirectly, in the disclosure of such Confidential Information, so long as such disclosures are made in a manner than complies with Section 6.5 below.

6.5 Permitted Disclosures. The Receiving Party may disclose Confidential Information belonging to the Disclosing Party to the extent (and only to the extent) such disclosure is reasonably necessary in the following instances: (i) subject to the proviso below, by either Party hereto, in order to comply with non-patent Applicable Law (including any securities Applicable Law or the rules of a securities exchange in a relevant jurisdiction) and with judicial process, if based on the reasonable advice of the Receiving Party’s counsel, such disclosure is necessary for such compliance; (ii) subject to the proviso below, by either Party hereto, in connection with prosecuting or defending litigation; and (iii) subject to the proviso below, by Dicerna, its Sublicensees, or their sublicensees in connection with any legal or regulatory requirements related to the Development, Manufacture or Commercialization of Product that use or employ Licensed Intellectual Property, such as labeling requirements, disclosures in connection with obtaining Regulatory Approvals, and the like, so long as the Development, Manufacture or Commercialization of Product has been and is performed in a manner that complies with the terms and conditions of Dicerna’s license to such Licensed Intellectual Property and reasonable steps are taken to maintain the confidentiality of said Confidential Information even when disclosed for legal or regulatory purposes; provided, however, that with respect to clause (i), (ii) and (iii) where legally permissible, (a) the Receiving Party shall notify the Disclosing Party of the Receiving Party’s intent to make any disclosure pursuant thereto sufficiently prior to making such disclosure so as to allow the Disclosing Party adequate time to take whatever action it may deem appropriate to protect the confidentiality of the information to be disclosed, including seeking protective orders or injunctive relief, and (b) consistent with Applicable Law, the Disclosing Party shall have the right to suggest reasonable changes to the disclosure to protect its interests, and the Receiving Party shall not unreasonably refuse to include such changes in its disclosure.

6.6 Press Release. Each Party shall publicize the execution of this Agreement by issuing its respective press release attached hereto as Exhibit E. After such initial press release, neither Party shall issue a press release or public announcement relating to the other Party or the collaboration activities undertaken pursuant this Agreement or the Supply Agreement without the prior written approval of the other Party, which approval shall not be unreasonably withheld, delayed or conditioned; provided, however, that (a) either Party may issue a press release or public announcement as required by Applicable Law; and (b) nothing in the foregoing will prevent Dicerna from issuing press releases and public announcements regarding the Product that do not reference Protiva, Tekmira or the LNP Technology, except that Dicerna shall (without Protiva’s consent) acknowledge that Protiva licensed to Dicerna the LNP Technology and Protiva Patents in respect of such Product. Except as otherwise provided herein, each Party agrees not to use the name, trademark, service xxxx, or design registered to the other Party or its Affiliates in any publicity, promotional, or advertising material, without prior written approval of the other Party.

ARTICLE VII –INDEMNIFICATION AND INSURANCE

7.1 Protiva Indemnification. Protiva agrees to indemnify Dicerna and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Dicerna Indemnitees”) against and to hold each of them harmless from any and all losses, costs, damages, fees or expenses (“Losses”) actually incurred or suffered by a Dicerna Indemnitee to the extent arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a Third Party based on: (a) any breach of any representation, warranty or covenant by Protiva under this Agreement; or (b) Protiva’s, its Affiliates’ or its Permitted Contractors’ gross negligence, willful misconduct or violation of Applicable Law. The foregoing indemnification shall not apply to the extent that any Losses are due to Dicerna’s, its Affiliates’ or its Sublicensees’ gross negligence or willful misconduct.

7.2 Dicerna Indemnification. Dicerna agrees to indemnify Protiva and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Protiva Indemnitees”) against and to hold each of them harmless from any and all Losses actually incurred or suffered by a Protiva Indemnitee to the extent arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a Third Party based on: (a) any breach of any representation, warranty or covenant by Dicerna under this Agreement; (b) Dicerna’s, its Affiliates’ or its Sublicensees’ gross negligence, willful misconduct or violation of Applicable Law; or (c) product recall, products’ liability or similar claims based on the Development or Commercialization of the Product (except to the extent that Protiva is required to indemnify the Dicerna Indemnitees for such Losses pursuant to the Supply Agreement). The foregoing indemnification obligations shall not apply to the extent that any Losses are due to Protiva’s, its Affiliates’ or its Permitted Contractors’ gross negligence or willful misconduct.

7.3 Tender of Defense; Counsel. Any Person (the “Indemnified Party”) seeking indemnification under this Article VII agrees to give prompt notice in writing to the other Party (the “Indemnifying Party”) of the assertion of any claim or the commencement of any action by any Third Party (a “Third Party Claim”) in respect of which indemnity may be sought under this Article. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its indemnification and hold harmless obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party. The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and shall be entitled to control and appoint lead counsel reasonably satisfactory to the Indemnified Party for such defense by written notice to the Indemnified Party within [***] after the Indemnifying Party has received notice of the Third Party Claim, in each case at its own expense; provided, however, that the Indemnifying Party must use Commercially Reasonable Efforts to conduct the defense of the Third Party Claim in a manner designed to protect the rights of the Indemnified Parties, and otherwise conduct such defense actively and diligently, thereafter in order to preserve its rights in this regard. The Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Third Party Claim and shall pay the fees and expenses of one counsel retained by the Indemnified Party if: (a) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment or allegation; (b) the Third Party Claim seeks an injunction or equitable relief against a Indemnified Party or any of its Affiliates; or (c) the Indemnifying Party has failed or is failing to prosecute or defend vigorously the Third Party Claim. Each Indemnified Party shall obtain the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned, before entering into any settlement of a Third Party Claim. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to enter into or approve any settlement of a Third Party Claim without the consent of the Indemnified Party (which may be withheld in its sole discretion), if the settlement (i) does not expressly unconditionally release all applicable Indemnified Parties and their Affiliates from all Losses with respect to such Third Party Claim, (ii) imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates, (iii) involves any admission of criminal or similar liability, or (iv) involves any monetary damages that may not be fully covered by the Indemnifying Party. In the event that the Indemnifying Party fails to assume the defense of the Third Party Claim in accordance with this Section 7.3, (1) the Indemnified Party may defend against the Third Party Claim in any manner it reasonably may deem appropriate, and (2) the Indemnifying Party shall remain responsible for any Losses of the Indemnified Party as a result of such Third Party Claim. In circumstances where the Indemnifying Party is controlling the defense of a Third Party Claim in accordance with this Section 7.3, the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose, in which case the fees and expenses of such separate counsel shall be borne by such Indemnified Party. Notwithstanding anything herein to the contrary, in circumstances where there is a conflict of interest that would reasonably make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party, the Indemnified Party shall be entitled to employ separate counsel, that is reasonably acceptable to the Indemnifying Party, and the Indemnifying Party shall pay the reasonable fees and expenses of such separate counsel. Each Party shall cooperate, and cause their respective Affiliates to cooperate in all reasonable respects, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith, all at the expense of the Indemnifying Party.

7.4 Insurance. Each Party shall maintain insurance, including product liability insurance, with respect to its activities under this Agreement regarding the Product in such amount as such Party customarily maintains with respect to similar activities for its other products. Each Party shall maintain such insurance for so long as it continues its activities under this Agreement, the Supply Agreement or the Quality Agreement, and thereafter for so long as such Party customarily maintains insurance for itself covering similar activities for its other products. Notwithstanding the foregoing, the Parties agree that during such time that Tekmira is an Affiliate of Protiva, Protiva shall have satisfied its obligations under this Section 7.4 provided it is covered by Tekmira’s existing insurance policies that also satisfy the obligations under this Section 7.4.

ARTICLE VIII –TERM AND TERMINATION

8.1 Term. The term of this Agreement (the “Term”) shall begin on the Effective Date and, unless terminated earlier as provided herein, shall continue in perpetuity.

8.2 Termination for Material Breach. If either Party commits a material breach or material default in the performance or observance of any of its obligations under this Agreement, and such breach or default continues without cure for a period of [***] after delivery by the other Party of written notice reasonably detailing such breach or default, then the non- breaching or non-defaulting Party shall have the right to terminate this Agreement, with immediate effect, by giving written notice to the breaching or defaulting Party. The Parties shall retain all rights and remedies (at law or in equity) in respect of any breach hereof.

8.3 Termination for Failure to Actively Develop or Commercialize. If Protiva reasonably concludes that Dicerna is failing to use Commercially Reasonable Efforts to actively Develop or Commercialize the Product, Protiva can request from Dicerna written confirmation that Dicerna or its Affiliates or Sublicensees are actively Developing and Commercializing the Product. Following receipt of such request, if Dicerna either: (a) fails to deliver such written confirmation to Protiva within [***] of Protiva’s delivery of such request; or (b) provides such written confirmation but does not thereafter, in a timely and diligent manner, actually use Commercially Reasonable Efforts to actively Develop or Commercialize the Product, Protiva may terminate this Agreement immediately on written notice to Dicerna.

8.4 Challenges of Protiva’s Patents or Tekmira Patents. If Dicerna or any of its Affiliates or Sublicensees directly and voluntarily commences or participates in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise asserts in writing (to Protiva or any of its Affiliates or to the U.S. Patent and Trademark Office) any claim, challenging or denying the validity of any of the Protiva Patents or Tekmira Patents, Protiva or Tekmira, as applicable, shall have the right to give notice to Dicerna (which notice must be given, if at all, within [***] after Protiva’s CEO or General Counsel first learns of the foregoing) that the licenses granted by Protiva to Dicerna hereunder to such Protiva Patent(s) or by Tekmira to Dicerna hereunder to such Tekmira Patent(s) shall terminate [***] following Dicerna’s receipt of such notice, and, unless Dicerna or its Affiliate or Sublicensees, as applicable, withdraws or causes to be withdrawn all such challenge(s) within such [***] period, such licenses to such Protiva Patent or Tekmira Patent, as applicable, shall so terminate; provided that if such action, proceeding or assertion is made by a Sublicensee the license shall only terminate with respect to the sublicense granted to such Sublicensee. Neither Dicerna’s, its Affiliates’, a Sublicensee, or any of their employees’ participating in or appearing in any such action, proceeding or claim as a result of receiving a subpoena or other court order requiring such participation or appearance will give rise to a right for Protiva to terminate as set forth in this Section 8.4.

8.5 Rights in Bankruptcy. Each Party (the “Insolvent Party”) shall promptly notify the other Party (the “Solvent Party”) in writing upon the initiation of any proceeding in bankruptcy, reorganization, dissolution, liquidation or arrangement for the appointment of a receiver or trustee to take possession of the assets of the Insolvent Party or similar proceeding under law for release of creditors by or against the Insolvent Party or if the Insolvent Party shall make a general assignment for the benefit of its creditors. To the extent permitted by Applicable Law, if the applicable circumstances described above shall have continued for [***] undismissed, unstayed, unbonded and undischarged, the Solvent Party may terminate this Agreement upon written notice to the Insolvent Party at any time. If Protiva is the Insolvent Party, the rights and remedies granted to Dicerna (as the Solvent Party) pursuant to this Section 8.5 shall be in addition to, and not in lieu of, Dicerna’s rights and remedies under Section 2.4(b) above.

8.6 Consequences of Termination; Survival.

(a) In the event this Agreement is properly terminated in accordance with its terms, then Dicerna’s rights and licenses under the Licensed Intellectual Property shall terminate upon the effective date of such termination, except as set forth in Sections 2.2(a) and 8.6(b). Termination of this Agreement shall not relieve the Parties of any obligation accruing prior to or upon such expiration or termination and the provisions of this Section 8.6, Section 3.3(b), Section 4.3(a) and ARTICLE I – (Definitions), ARTICLE V – (Intellectual Property), ARTICLE VI – (Confidential Information and Publicity), ARTICLE VII – (Indemnification and Insurance), and ARTICLE IX – (Miscellaneous) shall survive any expiration or termination of this Agreement.

Dicerna Announces License Agreement with Tekmira

to Advance Dicerna’s PH1 Development Program

WATERTOWN, Mass., November 17, 2014 – Dicerna Pharmaceuticals, Inc. (NASDAQ: DRNA), a leading developer of RNA interference (RNAi) therapeutics, today announced a licensing agreement for Dicerna to use Tekmira’s proprietary lipid nanoparticle (LNP) technology for delivery of DCR-PH1, Dicerna’s investigational product candidate for primary hyperoxaluria type 1 (PH1), a rare, inherited liver disorder that often results in kidney failure, and for which there are no approved therapies.

This announcement follows the successful testing of DCR-PH1 in combination with Tekmira's LNP technology in animal models, including mice and non-human primates. Under the agreement, Dicerna will pay Tekmira $2.5 million upfront, as well as $22 million in potential development milestones, and a mid-single-digit royalty on future PH1 sales.

Tekmira’s LNP system has shown in other human clinical studies to provide potent, safe and effective RNA delivery to hepatocytes (liver cells). Licensing Tekmira’s LNP will streamline the development path for DCR-PH1 and allows Dicerna to focus its LNP efforts on its oncology pipeline.

“Dicerna is focused on realizing the full clinical potential of our proprietary pipeline of highly targeted RNAi therapies by applying proven technologies,” said Xxxxxxx Xxxxxxxxx, Ph.D., Chief Executive Officer of Dicerna. “By drawing on Tekmira’s extensive and deep experience with lipid nanoparticle delivery to the liver, the agreement will streamline the development path for DCR-PH1. We look forward to initiating Phase 1 trials of DCR-PH1 in 2015, aiming to fill a high unmet medical need for patients with PH1.”

“This new agreement validates our leadership position in RNAi delivery and underscores the significant value we can bring to partners who leverage our LNP technology,” said Xx. Xxxx X. Xxxxxx, President and CEO of Tekmira. “Our LNP technology is enabling the most advanced applications of RNAi therapeutics in the clinic. We are excited to be working with Dicerna in advancing a needed, investigational therapeutic for the treatment of PH1."

About RNAi

RNAi therapeutics have the potential to treat a number of human diseases by "silencing" disease-causing genes. The discoverers of RNAi, a gene silencing mechanism used by all cells, were awarded the 2006 Nobel Prize for Physiology or Medicine. RNAi trigger molecules often require delivery technology to be effective as therapeutics.

About Tekmira’s LNP Technology

Tekmira LNP technology represents the most widely adopted delivery technology for the systemic delivery of RNAi triggers. Tekmira’s LNP platform is being utilized in multiple clinical trials by Tekmira and its partners. Tekmira’s LNP technology (formerly referred to as stable nucleic acid-lipid particles, or SNALP) encapsulates RNAi triggers with high efficiency in uniform lipid nanoparticles that are effective in delivering these therapeutic compounds to disease sites. Tekmira’s LNP formulations are manufactured by a proprietary method that is robust, scalable and highly reproducible, and LNP-based products have been reviewed by multiple regulatory agencies for use in clinical trials. LNP formulations comprise several lipid components that can be adjusted to suit the specific application.

About Primary Hyperoxaluria Type 1 (PH1)

PH1 is a rare, inherited liver disorder that often results in severe damage to the kidneys. The disease can be fatal unless the patient undergoes a liver-kidney transplant, a major surgical procedure that is often difficult to perform due to the lack of donors and the threat of organ rejection. In the event of a successful transplant, the patient must live the rest of his or her life on immunosuppressant drugs, which have substantial associated risks. Currently, there are no FDA approved treatments for PH1.

PH1 is characterized by a genetic deficiency of the liver enzyme alanine:glyoxalate-aminotransferase (AGT), which is encoded by the AGXT gene. AGT deficiency induces overproduction of oxalate by the liver, resulting in the formation of crystals of calcium oxalate in the kidneys. Oxalate crystal formation often leads to chronic and painful cases of kidney stones and subsequent fibrosis (scarring), which is known as nephrocalcinosis. Many patients progress to end-stage renal disease (ESRD) and require dialysis or transplant. Aside from having to endure frequent dialysis, PH1 patients with ESRD may experience a build-up of oxalate in the bone, skin, heart and retina, with concomitant debilitating complications. While the true prevalence of primary hyperoxaluria is unknown, it is estimated to be one to three cases per one million people.1 Fifty percent of patients with PH1 reach ESRD by their mid-30s.2

About DCR-PH1

Dicerna is developing DCR-PH1, which is in preclinical development, for the treatment of PH1. DCR-PH1 is engineered to address the pathology of PH1 by targeting and destroying the messenger RNA (mRNA) produced by HAO1, a gene implicated in the pathogenesis of PH1. HAO1 encodes glycolate oxidase, a protein involved in producing oxalate. By reducing oxalate production, this approach is designed to prevent the complications of PH1. In preclinical studies, DCR-PH1 has been shown to induce potent and long-term inhibition of HAO1 and to significantly reduce levels of urinary oxalate, while demonstrating long-term efficacy and tolerability in animal models of PH1.

About Dicerna’s Dicer Substrate Technology

Dicerna’s proprietary RNAi molecules are known as Dicer substrates, or DsiRNAs, so called because they are processed by the Dicer enzyme, which is the initiation point for RNAi in the human cell cytoplasm. Dicerna’s discovery approach is believed to maximize RNAi potency because the DsiRNAs are structured to be ideal for processing by Dicer. Dicer processing enables the preferential use of the correct RNA strand of the DsiRNA, which may increase the efficacy of the RNAi mechanism, as well as the potency of the DsiRNA molecules relative to other molecules used to induce RNAi.

About Tekmira

Tekmira Pharmaceuticals Corporation is a biopharmaceutical company focused on advancing novel RNAi therapeutics and providing its leading lipid nanoparticle (LNP) delivery technology to pharmaceutical partners. Tekmira has been working in the field of nucleic acid delivery for over a decade, and has broad intellectual property covering its delivery technology. Further information about Tekmira can be found at xxx.xxxxxxx.xxx. Tekmira is based in Vancouver, Canada and Seattle, USA.

About Dicerna

Dicerna Pharmaceuticals, Inc., is a biopharmaceutical company focused on the discovery and development of innovative treatments for rare, inherited diseases involving the liver and for cancers that are genetically defined. The company is using its proprietary RNA interference (RNAi) technology platform to build a broad pipeline in these therapeutic areas. In both rare diseases and oncology, Dicerna is pursuing targets that have been difficult to address using conventional approaches, but where connections between targets and diseases are well understood and documented. The company intends to discover, develop and commercialize novel therapeutics either on its own or in collaboration with pharmaceutical partners.

Under the agreement, Dicerna will pay Tekmira $2.5 million upfront and payments of $22 million in aggregate development milestones, plus a mid-single-digit royalty on future PH1 sales. This new partnership also includes a supply agreement with Tekmira providing clinical drug supply and regulatory support in the rapid advancement of the product candidate.

The agreement announced today follows the successful testing and demonstration of positive results combining Tekmira's LNP technology with DCR-PH1 in pre-clinical animal models.

Dicerna will use Tekmira’s third generation LNP technology for delivery of DCR-PH1, Dicerna’s Dicer substrate RNA (DsiRNA) molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies.

“This new agreement validates our leadership position in RNAi delivery with LNP technology, and it underscores the significant value we can bring to partners who leverage our technology. Our LNP technology is enabling the most advanced applications of RNAi therapeutics in the clinic, and it continues to do so. We are excited to be working with Dicerna to be able to advance a needed therapeutic for the treatment of PH1," said Xx. Xxxx X. Xxxxxx, Tekmira's President and CEO.

"As a core pillar of our business strategy, we continue to engage in partnerships where our technology improves the risk profile and accelerates the development programs of our collaborators and provides meaningful non-dilutive financing to TKMR," added Xx. Xxxxxx.
