is made, discovered, created, invented or generated by jointly by ProNAi and/or its Affiliate and Marina and/or its Affiliates in any activities or work under this Agreement shall be jointly owned by ProNAi and Marina (the “Joint
Intellectual Property”). Neither Party would assign their rights to the Joint Intellectual Property without the prior written consent of the other Party. 

6.2 Grant-Back License. Subject to the terms of the Agreement, ProNAi hereby grants to Marina (and its Affiliates) the [***] license,
with the right to sublicense (subject to the limitation below) in the Territory under the Improvement Patent Claims solely to use and practice the Improvement Patent Claims in connection with the manufacture, use or sale of the Licensed Technology
outside the Field of Use. In no event shall Marina (or its Affiliates or sublicensees) grant, or have any rights to grant, any sublicense under the foregoing license that is separate from a license (to the applicable sublicensee) under Marina
Technology. Marina shall pay to ProNAi a royalty of [***]% of the net sales of any products sold by Marina or its Affiliates or sublicensees where the manufacture, use or sale of such product is claimed by a valid claim in the issued Improvement
Patent Claims (where the terms “net sales” and “valid claim” have the same meanings as Net Sales and Valid Claims applied mutatis mutandis to the situation involving such product sold by Marina (or its Affiliate or
sublicensee) and Improvement Patent Claim). 
 6.3 Prosecution and Maintenance. 

(a) Marina shall, at its expense, file, prosecute, defend and maintain, including conducting re-examination,
reissue, opposition and interference proceedings (and any other similar patent proceedings) regarding, the Licensed Patents before all patent authorities (collectively, “Prosecution”). Marina shall keep ProNAi reasonably
informed of such Prosecution efforts and results. Marina shall not abandon any patent rights in the Licensed Patents without first notifying ProNAi in writing at least [***] days prior to any such abandonment. If Marina intends to abandon any such
rights of Licensed Patent, or does not conduct the Prosecution of any claim or patent application or patent within the Licensed Patents in any specific country, after ProNAi’s request, then ProNAi shall have the right, on written notice to
Marina, to undertake the Prosecution of such claims, applications or patents at ProNAi’s sole cost and expense, and in such case Marina shall do all things to provide ProNAi with the right and opportunity to conduct the Prosecution of such
claim or patent application or patent.

 CONFIDENTIAL 
  

(b) ProNAi shall, at its expense and discretion, control the Prosecution of all Joint Intellectual Property before all patent
authorities. ProNAi shall keep Marina reasonably informed of such Prosecution efforts and results. ProNAi shall not abandon any patent rights in the Joint Intellectual Property without first notifying Marina in writing at least [***] days prior to
any such abandonment. If ProNAi intends to abandon any such rights of the Joint Intellectual Property, or does not conduct the Prosecution of any claim or patent application or patent within the Joint Intellectual Property in any specific country,
after Marina’s request, then Marina shall have the right, on written notice to ProNAi, to undertake the Prosecution of such claims, applications or patents at Marina’s sole cost and expense, and in such case ProNAi shall do all things to
provide Marina with the right and opportunity to conduct the Prosecution of such claim or patent application or patent. 
 6.4
Infringement by Third Parties. If requested by ProNAi, Marina shall use [***] to enforce the Licensed Patents against infringers that are causing a material negative impact on ProNAi (or its Affiliate or Sublicensee) in the market for a Licensed
Product due to the infringement of the Licensed Patents. Marina shall keep ProNAi fully informed of the progress and results of any such enforcement action. Any recoveries in any such enforcement actions against an infringement brought under this
Section 6.4 shall be used first to reimburse Marina’s out-of-pocket costs and expenses (including attorneys’ fees) for such action and any remainder shall be shared equally by the licensees of the Licensed Patents affected by the
infringement action. Marina shall not enter into any settlement of any action under this Section 6.4 that materially negatively affects ProNAi’s (or its Affiliate’s or Sublicensee’s) rights or interests under this Agreement
without ProNAi’s written consent, which consent shall not be unreasonably withheld or delayed. If a Third Party is infringing a Licensed Patent by making, using or selling a product in the Field of Use (a “Field
Infringement”), and Marina does not enforce the Licensed Patent against such Field Infringement within [***] days after request by ProNAi, or ceases such enforcement without causing the Field Infringement to terminate, then
thereafter ProNAi shall have the right to enforce the applicable Licensed Patents against such Field Infringement, at its expense, and shall keep Marina reasonably informed of such enforcement. In any such enforcement by ProNAi, Marina agrees to
join the action as a party plaintiff (at ProNAi’s expense) if required for ProNAi to have standing to pursue the action and to cooperate and provide all reasonable assistance in ProNAi’s enforcement. 

6.5 Defense of Third Party Actions. Each Party shall promptly notify the other Party upon receiving written notice of any potential
infringement, or any Third Party Claim or action against Marina or ProNAi or any of their Affiliates or Sublicensees for possible infringement, of a Third Party patent right resulting from the practice or use by ProNAi (or its Affiliate or
Sublicensee) of the Licensed Technology under this Agreement. Each Party shall be responsible for defending, and shall control the defense of, any such action brought against such Party. 

ARTICLE 7 

REPRESENTATIONS, WARRANTIES AND COVENANTS 

7.1 Representations and Warranties of Marina. As of the Effective Date, Marina hereby represents and warrants to ProNAi as follows:

breach of, any material agreement, instrument or understanding, oral or written, to which it is a party or by which it may be bound, nor violate any material law or regulation of any court, governmental body or administrative or other agency having
jurisdiction over it. Marina hereby covenants that it and its Affiliates shall not enter into any agreement that will conflict with its obligations and covenants in this Agreement or prevent or interfere with its performance of such obligations.

ARTICLE 8 

INDEMNIFICATION 

8.1 Indemnification by Marina. Marina hereby agrees to defend, hold harmless and indemnify ProNAi and its Affiliates, and each of their
respective officers, directors and employees (collectively, the “ProNAi Indemnitees”), from and against any and all Losses arising out of any Third Party Claim based upon or resulting from: (i) any of
Marina’s representations and warranties set forth in Section 7.1 of this Agreement being untrue in any material respect when made; (ii) Marina’s failure to perform, in any material respect, any covenant or obligation of Marina
set forth in this Agreement; and (iii) Marina’s gross negligence or willful misconduct; except, in each case, to the extent any such Losses result from the gross negligence or willful misconduct of ProNAi Indemnitees or from the breach of
any representation or warranty or obligation under this Agreement by ProNAi or its Affiliate. 
 8.2 Indemnification by ProNAi.
ProNAi hereby agrees to defend, hold harmless and indemnify Marina and its Affiliates, and each of their respective officers, directors and employees (collectively, the “Marina Indemnitees”), from and against
any and all Losses arising out of any Third Party Claim based upon or resulting from: (i) any of ProNAi’s representations and warranties set forth in Section 7.2 of this Agreement being untrue in any material respect when made;
(ii) ProNAi’s or its Affiliate’s failure to perform, in any material respect, any covenant or obligation of ProNAi set forth in this Agreement; (iii) the exercise or practice by ProNAi, its Affiliates or Sublicensees of the
licenses granted to ProNAi under Sections 2.1 (excluding any such Claim that alleges that the exercise or practice of the Licensed Technology infringes a patent or misappropriates other intellectual property of the Third Party);
or (iv) the development, manufacture or Commercialization of any Licensed Product by or for ProNAi, its Affiliates or Sublicensees; except, in each case, to the extent any such Losses result from the gross negligence or willful
misconduct of Marina Indemnitees or from the breach of any representation or warranty or covenant or obligation under this Agreement by Marina. 

  
 16 

 CONFIDENTIAL 
  

8.3 Indemnification Procedures. Each Party (Marina on behalf of Marina Indemnitees, or ProNAi on behalf of ProNAi Indemnitees) will
promptly notify the other Party when it becomes aware of a Claim for which indemnification may be sought hereunder. To be eligible to be indemnified for a Claim, a person seeking indemnification (the “Indemnified
Party”) shall (i) provide the Party required to indemnify such person (the “Indemnifying Party”) with prompt written notice of the Claim giving rise to the indemnification obligation
under this Article 8, provided that, the failure to provide such prompt notice shall not relieve the Indemnifying Party of any of its obligations under this Article 8 except to the extent the Indemnifying Party is actually prejudiced thereby;
(ii) provide the Indemnifying Party with the exclusive ability to defend (with the reasonable cooperation of the Indemnified Party) against the Claim; and (iii) not settle, admit or materially prejudice the Claim, without the Indemnifying
Party’s prior written consent. The Indemnified Party shall reasonably cooperate with the Indemnifying Party, at the Indemnifying Party’s expense, in the defense of any Claim. Notwithstanding the foregoing, the Indemnified Party shall have
the right to participate in and have its own counsel participate in any action or proceeding for which the Indemnified Party seeks to be indemnified by the Indemnifying Party. Such participation shall be at the Indemnified Party’s expense,
unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party
and the Indemnified Party and representation of both Parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Indemnifying Party’s obligations under Section 8.1 or 8.2, as the case
may be, shall not apply to the extent of the Indemnified Party’s failure to take reasonable action to mitigate any Losses. The Indemnifying Party shall not settle or compromise, or consent to the entry of any judgment with respect to, any
Claim, without the prior written consent of the Indemnified Party, which will not be unreasonably withheld or delayed. 
 8.4
Insurance. ProNAi shall, at its own expense, procure and maintain during the Term and for a period of [***] years thereafter, insurance policy/policies, including product liability insurance, adequate to cover its obligations hereunder and which
are consistent with normal business practices of prudent companies similarly situated. 
 ARTICLE 9 

CONFIDENTIALITY 

9.1 Treatment of Confidential Information. The Parties agree that during the Term, and for a period of [***] years after this Agreement
expires or terminates, a Party receiving Confidential Information of the other Party shall (i) maintain in confidence such Confidential Information; (ii) not disclose such Confidential Information to any Third Party without prior written
consent of the disclosing Party, except as otherwise permitted in this Article 9; and (iii) not use such Confidential Information for any purpose other than the performance of or exercise of its rights under this Agreement.

 CONFIDENTIAL 
  

9.2 Authorized Disclosure. 

(a) If, based upon the advice of legal counsel skilled in the subject matter, a Party is required to disclose specific Confidential
Information of the other Party to comply with an Applicable Law, regulation, legal process, or order of a government authority or court of competent jurisdiction, the Party may disclose such Confidential Information only to the entity or person
required to receive such disclosure; provided, however, that the Party required to disclose such Confidential Information shall (a) to the extent permitted by such law, regulation, process, order or rules, first have given prompt (but in no
event less than five (5) business days) advance notice to such other Party to enable it to seek any available exemptions from or limitations on such disclosure requirement and shall reasonably cooperate in such efforts by the other Party,
(b) furnish only the portion of the Confidential Information which is legally required to be disclosed; (c) use all reasonable efforts to secure confidential protection of such Confidential Information, and (d) continue to perform its
obligations of confidentiality and non-use set out in this Article 9. 
 (b) ProNAi (and its Affiliates and Sublicensees) may
disclose Confidential Information of Marina to Regulatory Authorities to the extent such disclosure is reasonably necessary in regulatory filings required for the development and/or commercialization of Licensed Products. In addition, each Party may
disclose Confidential Information of the other Party to the extent such disclosure is reasonably necessary in the following instances: filing or prosecuting patents as permitted by this Agreement; and disclosure to Affiliates and Sublicensees and
potential Sublicensees or other similar commercial partners, who need to know such information for the development, manufacture and commercialization of Licensed Products, to bankers, lawyers, accountants, agents or other Third Parties in connection
with due diligence or similar investigations, and to potential Third Party investors in confidential financing documents or potential acquirers or merger partners in confidence pursuant to due diligence; provided that any such Sublicensee, licensee,
contractor, employee, consultant, banker, lawyer, accountant, agent or Third Party is bound by obligations of confidentiality and non-use at least as restrictive as those set forth herein. In the case of each disclosure, the Party making such
disclosure shall use reasonable efforts to obtain confidential treatment of any such disclosure, and shall not disclose Confidential Information of the other Party other than is reasonably necessary. 

9.3 Publicity; Terms of Agreement. The Parties shall treat the existence and material terms of this Agreement as confidential and shall
not disclose such information to Third Parties without the prior written consent of the other Party or except as provided in Section 9.2 (treating such information as Confidential Information for purposes of Section 9.2) or as provided
below. The Parties agree that upon execution of this Agreement or shortly thereafter, the Parties shall issue a joint press release, such press release attached hereto as Appendix B. Except for such press release or as otherwise required by
Applicable Law or applicable stock exchange requirements, neither Marina nor ProNAi shall issue or cause the publication of any other press release or public announcement with respect to the transactions contemplated by this Agreement without the
express prior approval of the other Party, which approval shall not be unreasonably withheld or delayed; provided that, each of Marina and ProNAi may make any public statement in response to questions by the press, analysts, investors or those
attending industry conferences or financial analyst calls, or issue press releases, so long as any such public statement or press release is not inconsistent with prior public disclosures or public statements approved by the other Party pursuant to
this Section 9.3 and which do not reveal non-public  

  
 18 

 CONFIDENTIAL 
  

information about the other Party. With respect to complying with the disclosure requirements of the Securities and Exchange Commission or other regulatory agencies, in connection with any
required filing of this Agreement with such agency, the Parties shall consult with one another concerning which terms of this Agreement shall be requested to be redacted in any public disclosure of the Agreement by the agency, and each Party shall
seek confidential treatment by the agency in public disclosure of the Agreement by the agency for all sensitive commercial, financial and technical information, including the definitions of Licensed Products and Field of Use, and any dollar amounts
set forth herein. 
 9.4 Injunctive Relief. Given the nature of the Confidential Information and the competitive damage that would
result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 9. In addition to all other
remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 9. 

ARTICLE 10 

TERM AND TERMINATION

action taken against such Bankrupt Party in bankruptcy or seeking liquidation, reorganization, dissolution, a winding-up arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization or
similar act or law of any jurisdiction now or hereafter in effect and is not dismissed or converted into a voluntary proceeding governed by clause (a) above within sixty (60) days after filing; or (e) there shall have been issued a
warrant of attachment, execution, distraint or similar process against any substantial part of the property of such Bankrupt Party and such event shall have continued for a period of sixty (60) days and none of the following has occurred:

(c) Termination for ProNAi Default. Upon any Default by ProNAi under this Agreement, Marina may notify ProNAi of such Default and
require that ProNAi cure such Default, which cure period shall be not shorter than sixty (60) days of Marina’s notice for any Default of a payment obligation under this Agreement, or one hundred and twenty (120) days of Marina’s
notice for any other Default. In the event ProNAi shall not have cured the Default by the end of the applicable cure period, Marina may terminate this Agreement immediately upon written notice to ProNAi. Notwithstanding the foregoing cure period,
non-payment of the Initial Upfront License Fee in accordance with Section 5.1 shall automatically and immediately terminate this Agreement. 

(d) Termination for Marina Default. Upon any Default by Marina under this Agreement, ProNAi may notify Marina in writing of such Default
and require that Marina cure such Default within one hundred and twenty (120) days of ProNAi’s notice. In the event Marina shall not have cured the Default by the end of the cure period, ProNAi may terminate this Agreement in its entirety,
or on a country-by-country basis, immediately upon written notice to Marina. 
 10.3 Effects of Termination. Upon termination
of this Agreement pursuant to Section 10.2: (a) all licenses granted hereunder to ProNAi shall revert to Marina; (b) all sublicenses granted by ProNAi under the rights or licenses granted to ProNAi under this Agreement shall survive
such termination, provided that the applicable Sublicensees are not in material breach of such sublicense agreements, and shall become direct licenses with Marina except that Marina shall not have any obligations under any such
sublicense agreements that are greater than the obligations of Marina under this Agreement; (c) ProNAi (and its Affiliates) shall immediately cease all development and Commercialization of any Licensed Products that contain Licensed Know-How

desist from all use or display of Marina’s Trademark and will destroy all goods, materials and papers upon which Marina’s Trademark appears and delete all uses of the Trademark on any other media, unless otherwise authorized in writing by
Marina. For the avoidance of doubt, any technology, materials, intellectual property and information in ProNAi’s possession for use and application under the Original License Agreement for the product known as [***] shall not be affected by
termination of this Agreement.

10.4 Survival. The following provisions shall survive any expiration or termination of this Agreement: Articles [***], and Sections
[***] and the applicable Sections of Article 1 (as needed to apply to the foregoing surviving Sections and Articles). Termination of this Agreement shall not relieve the Parties of any liability which accrued hereunder prior to the effective date of
such termination nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any Default of this Agreement nor prejudice either Party’s right to obtain performance of any
obligation. 
 ARTICLE 11 

DISPUTE RESOLUTION 

11.1 Disputes. In the event that any issue, controversy or claim between the Parties arises out of, relating to or in connection with,
any provision of this Agreement, or the rights or obligations of the Parties hereunder (a “Dispute”), the Parties shall try to settle such Dispute and their differences amicably between themselves. Either Party
may initiate such informal dispute resolution by sending written notice of the Dispute to the other Party, and within [***] days after such notice appropriate representatives of the Parties shall meet for attempted resolution by good faith
negotiations. If such representatives are unable to resolve promptly such Dispute, it shall be referred to the Parties executive officers for discussion and resolution. If such personnel are unable to resolve such Dispute within [***] days of
initiating such negotiations, unless otherwise agreed by the Parties, such dispute shall be finally settled under Section 11.2. 

11.2 Arbitration. For any Dispute involving amounts owed under the Agreement, or whether a Party has breached its obligations under the
Agreement (and/or has cured such breach), such Dispute (if not resolved by the Parties under Section 11.1) shall be resolved by final and binding arbitration in accordance with this Section 11.2, under the Commercial Arbitration Rules and
Supplementary Procedures for Large Complex Disputes of the American Arbitration Association (“AAA”) by a single arbitrator. Either Party may, following the end of the good faith negotiation period referenced in
Section 11.1, refer any such Dispute to arbitration by submitting written notice to the other Party. Within [***] Business Days of delivery of such notice, the Parties shall meet and discuss in good faith and agree on (a) an arbitrator to
resolve the issue, which arbitrator shall be neutral and independent of both Parties and all of their respective Affiliates, shall have significant experience and expertise in licensing and partnering agreements in the pharmaceutical industry and
other relevant experience and (b) any changes in these arbitration provisions or the rules of arbitration which are herein adopted, in an effort to expedite the process and otherwise ensure that the process is appropriate given the nature of
the dispute and the values at risk. If the Parties cannot agree on such arbitrator within [***] days of request by a Party for arbitration, then such arbitrator shall be appointed by AAA, which arbitrator must meet the foregoing criteria. The
arbitration shall be held in New York, New York, and the proceedings shall be conducted in the English language. The arbitrators may proceed to an award, notwithstanding the failure of either Party to participate in the proceedings. The arbitrator
shall be instructed that time is of the essence in the arbitration proceeding. The arbitrator shall, within [***] calendar days after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential
findings and conclusions on which the award is based, including the calculation of any damages awarded (if applicable). The arbitrator shall be authorized to award compensatory damages, but shall not be authorized to (i)  

 
 *Confidential Treatment Requested. 

  
 21 

 CONFIDENTIAL 
  

award non-economic or punitive damages to the extent expressly excluded under this Agreement, or (ii) reform, modify or materially change this Agreement or any other agreements
contemplated hereunder; provided, however, that the damage limitations described in part (i) of this sentence will not apply if such damages are statutorily imposed. Judgment on the award rendered by the arbitrator may be enforced in any court
having competent jurisdiction thereof, or application may be made to the court for a judicial recognition of the award or an order of enforcement as the case may be, subject only to revocation on grounds of fraud or clear bias on the part of the
arbitrator. Notwithstanding anything contained in this Section 11.2 to the contrary, either Party shall have the right to seek equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary
restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration
proceeding. The Parties agree that the arbitration shall be kept confidential and that the existence of the proceeding and any element of its (including any pleadings, briefs or other documents submitted or exchanged, any testimony or other oral
submissions and any awards) shall not be disclosed beyond the arbitrator, the Parties, their counsel and any person necessary to the conduct of the proceeding, except as may lawfully be required in judicial proceedings relating to the arbitration or
otherwise.

JOINT PRESS RELEASE 

 

			
	

		

 Marina Biotech and ProNAi Therapeutics Announce License 

Agreement for the Development of DNAi-based Therapeutics 

- ProNAi Therapeutics will develop oncology-focused compounds utilizing its proprietary DNAi 

technology combined with Marina Biotech’s novel SMARTICLES® liposomal delivery

 technology - 
 Bothell, WA and Ann
Arbor, MI March 14, 2012 – Marina Biotech, Inc. (OTCQX: MRNA), a leading nucleic acid-based drug discovery and development company, and ProNAi Therapeutics, Inc. (ProNAi), a privately-held biotechnology company pioneering DNA interference
(DNAi) therapies for cancer, announced today that the Companies have entered into an Exclusive License Agreement regarding the development and commercialization of DNAi-based therapeutics utilizing Marina Biotech’s novel SMARTICLES® liposomal delivery technology. ProNAi will have full responsibility for the development and commercialization of any products arising under the Agreement. Under terms of the Agreement, Marina
Biotech could receive up to $14 million for each gene target in total upfront, clinical and commercialization milestone payments, as well as royalties on sales, with ProNAi having the option to select any number of additional gene targets. For
example, if ProNAi licenses five products over time under this Agreement, Marina Biotech could receive up to $70 million in total milestones, plus royalties. Further terms of the Agreement were not disclosed. 

“We are pleased that twenty-two patients have been dosed with PNT2258 in our Phase I clinical trial in advanced solid tumor patients to evaluate safety
and tolerability, maximum tolerated dose, pharmacokinetics and pharmacodynamics. PNT2258 is our first DNAi oligonucleotide targeted against the anti-apoptotic bcl-2 oncogene and encapsulated in Marina’s SMARTICLES® technology. This novel delivery technology offers protection for the DNAi oligonucleotide during systemic administration with good circulation times and extrahepatic tumor exposure. DNAi are
short single-strand unmodified oligonucleotides designed to silence genes by interfering with DNA. The DNAi silencing approach is differentiated from that of RNAi, antisense or miRNA in that it targets genomic sequences within noncoding region of
DNA disrupting transcription. The progress and delivery validation in the clinic this past year on the novel DNAi-SMARTICLES® formulation gives us confidence to bring forward more first in
class drug candidates alone or with partners. ProNAi is now positioned to advance additional cancer therapies from its pre-clinical leads targeting other oncogenes such as c-myc and k-ras while also exploring other disease targets in areas such as
inflammation and genetics diseases,” said Charles L. Bisgaier, Ph.D., President and CEO of ProNAi Therapeutics.

“We are extremely pleased to have entered into a relationship with a company like ProNAi who is developing a first-in-class nucleic acid
therapeutic,” stated J. Michael French, President and CEO of Marina Biotech. “In addition, we are excited to see the continued advancement of oligonucleotide-based therapeutics using our SMARTICLES® technology. Besides advancements within our own internal research programs, we have now been able to establish two license agreements broadening the application of the SMARTICLES® technology to the systemic administration of both single and double-stranded oligonucleotide therapeutics. We look forward to the rapid advancement of ProNAi Therapeutics’ clinical pipeline
and the opportunity to bring novel therapeutics to patients in need.” 
 ProNAi is conducting an open-label, single arm, Phase I dose-escalation study
of PNT2258 in patients with advanced solid tumors for which no standard therapy exists at START in San Antonio Texas. PNT2258 is ProNAi’s first drug candidate from the DNAi drug platform. Patients receive PNT2258 as an intravenous infusion once
daily for 5 consecutive days (Days 1-5) of every 21-day cycle (3 weeks). ProNAi plans to report the results of this Phase I study at oncology conferences later this year and initiate the next Phase I/II safety and efficacy studies in select cancer
patients based upon the safety and dose findings from this Phase I study.
