Amendment to Agreement with Tom Keiser

 Exhibit 10.104 
 AMENDMENT TO AGREEMENT 
 Gap Inc. (“Company”) and Tom Keiser (referred to in the
second person) hereby amend the letter agreement dated November 18, 2009, replacing the section entitled “Termination/Severance” with the following provision: 
 Termination/Severance. In the event that your employment is involuntarily terminated by the Company for reasons other than For Cause (as defined below) prior to February 13, 2015, the Company
will provide you the following after your “separation from service” within the meaning of Section 409A of the Internal Revenue Code (the “Separation from Service”), provided you sign a general release of
claims in the form requested by the Company and it becomes effective within 45 calendar days after such Separation from Service (the “Release Deadline”):
 (1) Your then current salary, at regular pay cycle intervals, for eighteen months commencing in the first regular pay cycle following the Release Deadline (the “severance period”). Payments
will cease if you accept other employment or professional relationship with a competitor of the Company (defined as another company primarily engaged in the apparel design or apparel retail business or any retailer with apparel sales in excess of
$500 million annually), or if you breach your remaining obligations to the Company (e.g., your duty to protect confidential information, agreement not to solicit Company employees). Payments will be reduced by any compensation you receive
during the severance period from other employment or professional relationship with a non-competitor.
 (2) Through
the end of the period in which you are receiving payments under paragraph (1) above, if you properly elect and maintain COBRA coverage, payment of a portion of your COBRA premium in a method as determined by the
Company. This payment may be taxable income to you and subject to tax withholding. Notwithstanding the foregoing, the Company’s payment of the monthly COBRA premium shall cease immediately if the Company determines in its discretion that paying
such monthly COBRA premium would result in the Company being in violation of, or incurring any fine, penalty, or excise tax under, applicable law (including, without limitation, any penalty imposed for violation of the nondiscrimination requirements
under the Patient Protection and Affordable Care Act or guidance issued thereunder). 
 (3) Through the end of the
period in which you are receiving payments under paragraph (1) above, reimbursement for your costs to maintain the same or comparable financial counseling program the Company provides to senior executives in effect at the time of
your Separation from Service. The amount of expenses eligible for reimbursement during a calendar year shall not affect the expenses eligible for reimbursement in any other calendar year. Reimbursement shall be made on or before the last
day of the calendar year following the calendar year in which the reimbursement is incurred but not later than the end of the second calendar year following the calendar year of your Separation from Service. 

The payments in (1) and (3) above are taxable income to you and are subject to tax withholding. If the aggregate amount that would be
payable to you under paragraphs (1) and (3) above through the date which is six months after your Separation from Service exceeds the limit under Treas. Reg. Section 1.409A-1(b)(9)(iii)(A) and you are a
“specified employee” under Treas. Reg. Section 1.409A-1(i) on the date of your Separation from Service, then the excess will be paid to you no earlier than the date which is six months after the date of such
separation (or such earlier time permitted under Section 409A(a)(2)(B)(i) of the Internal Revenue Code). This delay will only be imposed to the extent required to avoid the tax for which you would otherwise be liable under
Section 409A(a)(1)(B) of the Internal Revenue Code. Any delayed payment instead will be made on the first business day following the expiration of the six month period, as applicable (or such earlier time permitted under
Section 409A(a)(2)(B)(i) of the Internal Revenue Code).

 The term “For Cause” shall mean a good faith determination by the Company that your employment
be terminated for any of the following reasons: (1) indictment, conviction or admission of any crimes involving theft, fraud or moral turpitude; (2) engaging in gross neglect of duties, including willfully failing or refusing to
implement or follow direction of the Company; or (3) breaching Gap Inc.’s policies and procedures, including but not limited to the Code of Business Conduct. 
 At any time, if you voluntarily resign your employment from Gap Inc. or your employment is terminated For Cause, you will receive no compensation, payment or benefits after your last day of
employment. If your employment terminates for any reason, you will not be entitled to any payments, benefits or compensation other than as provided in this letter.

results that cannot support Regulatory Approval or further development or commercial activity; 

  
 8 

 [CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION,

projects, from sources that may include federal and other grants, foundations, partners or private capital. The availability of such financing is uncertain and ProNAi makes no warranty or assurance that such attempts will be successful; 

(d) For the avoidance of doubt, deviations from or changes to the development program on Licensed Product due to
unexpected, unpredictable, inaccurate, or otherwise undesirable results as described in this Section 3.3 (including, without limitation, results indicating toxicity issue or a lack of efficacy) shall not be considered a failure of ProNAi to
meet its obligations hereunder and it shall not be deemed a material breach to this Agreement per Section 10.2(c) of this Agreement. 
 3.4 Regulatory Matters Generally. ProNAi (or its Affiliate or Sublicensee, as applicable) shall have the exclusive rights to manage and conduct all regulatory activities relating Licensed Products
for use in the Field of Use in the Territory. ProNAi may subcontract all or part of the conduct of such regulatory activities to appropriately qualified third parties.

all INDs and that are necessary or useful to conduct clinical studies of the Licensed Products, and all NDAs and other applications for Regulatory Approval to market and sell Licensed Products in the Field of Use in the Territory, and all amendments

 For clarity each of the above milestone payments shall be paid only once for a particular Licensed
Product, regardless if any such Milestone Event is achieved more than once, [***]. Further, if a particular Licensed Product achieves a particular Milestone Event under subclause (i) of the above table without having achieved a previous
Milestone Event in such subclause (i), then such previous Milestone Event shall be deemed also achieved, and the Milestone Payment associated with such Milestone Event shall then be paid with the achievement of the subsequent Milestone Event. For
illustrative purposes only, if the [***] Milestone Event as set forth in (i)(3) in the table above is not achieved for a Licensed Product but the [***] Milestone Event as set forth in (i)(4) above is achieved for such Licensed Product, then the
Milestone Payment for achievement of the Milestone Event in clause (i)(3) ($[***]) will be paid when the Milestone Payment for (i)(4) is paid. The total amount of milestone payments payable for a particular Licensed Product under the above shall
not, in any event, exceed $[***] under subclause (i) of the above table and $14,000,000 in total. 
 (b) ProNAi
shall [***] notify Marina of the achievement of any Milestone Event for each Licensed Product. All Milestone Payments under subsection (a) above are non-refundable and non-creditable, and shall be due within [***] days of achievement of the
applicable Milestone Event.

 5.4 Royalties. In part consideration of the license rights granted by Marina
under this Agreement, ProNAi shall pay royalties to Marina on Net Sales by ProNAi or any of its Affiliates or Sublicensees of Licensed Products during the Royalty Term for sales of License Product in country(ies) where such sale would infringe,
absent the license granted in Section 2.1, a Valid Claim of an issued Licensed Patent, ProNAi shall pay to Marina royalties equal to [***]% of the Net Sales revenue recognized by ProNAi or any of its Affiliates or Sublicensees from such sales.

 5.5 Anti-Stacking Provisions. If ProNAi or its Affiliate owes to one or more Third Parties, under license agreement(s)
granting ProNAi (or its Affiliate or Sublicensee) license rights covering patents (or other intellectual property rights) that are needed to make, use, sell or otherwise Commercialize the Licensed Technology as contained in a Licensed Product,
royalties or similar payments on sales of such Licensed Products, then ProNAi may reduce the royalties owed to Marina under Section 5.4 based on such sales of Licensed Product by [***]% of the royalty or similar payments actually paid to such
Third Parties, provided that ProNAi shall not reduce any particular royalty payment to Marina by more than [***]% of the amount otherwise owed under the royalty provisions of Section 5.4 for the applicable royalty period. 

5.6 Payment of Royalty. The royalty obligation under Section 5.4 shall accrue upon the sales of a Licensed Product in each
particular country in the Territory, commencing upon [***], and such obligation shall end upon the expiration of the Royalty Term applicable to such Licensed Product in such country. All such royalty payments are non-refundable and non-creditable
and shall be due within [***] days of the end of each [***] and are payable in immediately available funds. ProNAi shall notify Marina in writing promptly upon the First Commercial Sale of Licensed Product in each country and thereafter ProNAi shall
furnish Marina with a written report (the “Royalties Report”) for each completed [***] showing, on a country-by-country basis, according to the volume of units of Licensed Product sold in each such country (by SKU) during the
reporting period (whether Licensed Product is sold by ProNAi or its Affiliates or Sublicensees): (a) the gross invoiced sales of the Licensed Product sold in each country during the reporting period, and the amounts deducted therefrom to
determine Net Sales from such gross invoiced sales; (b) the royalties payable in dollars, if any, which shall have accrued hereunder based upon Net Revenues from sales of Licensed Product; and (c) the withholding taxes, if any, required by
Applicable Law to be deducted in respect of such sales (provided that, as to sales by Sublicensees, ProNAi shall report only the net sales numbers (using the definition for such term in the applicable sublicense agreement) as reported by the
Sublicensee, if such Sublicensee does not report gross invoiced sales numbers). With respect to sales of Licensed Product invoiced in US dollars, the gross invoiced sales, Net Revenues and royalties payable shall be expressed in the Royalties Report
in US Dollars. With respect to sales of Licensed Product invoiced in a currency other than US dollars, the gross invoiced sales, Net Sales and royalties payable shall be expressed in the Royalties Report in the domestic currency of the party making
the sale as well as in the US dollar equivalent of the Royalty payable and the exchange rate used in determining the amount of US dollars. The US dollar equivalent shall be calculated on a calendar-month basis using the average monthly interbank
rate listed in the Wall Street Journal.

 5.7 Currency Restrictions. If at any time legal restrictions in any country in
the world prevent the prompt remittance of any payments with respect to sales in that country, ProNAi shall have the right and option upon written notice to Marina to make such payments by depositing the amount thereof in local currency to
Marina’s account (or such other designated nominee by Marina) in a bank or depository in such country. 
 5.8
Taxes. In the event that laws, rules or regulations require ProNAi to withhold taxes with respect to any payment to be made by ProNAi to Marina pursuant to this Agreement, ProNAi will notify Marina of such withholding requirement prior to
making the payment to Marina and shall make such withholding from such payment of the required amount of withholding and shall make the required tax payment to the appropriate tax authority, and provide such assistance to Marina, including the
provision of such documentation as may be required by a tax authority, as may be reasonably necessary in Marina’s efforts to claim an exemption from or reduction of such taxes. 

5.9 Late Payments. All fees and royalties due under this Agreement not received within the period due shall bear interest from the
date they are due until the date they are paid at the rate of [***] percent ([***]%) per annum or the maximum rate permitted by law, whichever is less. 
 5.10 Audit. ProNAi and its Affiliates shall keep complete and accurate records of the underlying revenue and expense data relating to the calculations of Net Sales, Sublicensee revenues and
payments required under this Agreement. Marina shall have the right, at its own expense and no more than [***], to have an independent, certified public accountant, selected by Marina and reasonably acceptable to ProNAi, review all such records upon
reasonable notice and during regular business hours and under obligations of strict confidence, for the sole purpose of verifying the basis and accuracy of payments required and made under this Agreement within the prior [***] month period. No
calendar quarter may be audited more than one time. ProNAi shall receive a copy of each audit report promptly from Marina. Should the inspection lead to the discovery of a discrepancy to Marina’s detriment, ProNAi shall pay the amount of the
discrepancy in Marina’s favor within [***] days after being notified thereof. Marina shall pay the full cost of the inspection unless the discrepancy is greater than [***] percent ([***]%), in which case ProNAi shall pay to Marina the actual
cost charged by such accountant for such inspection. If such audit shows a discrepancy in ProNAi’s favor, then ProNAi may credit the amount of such discrepancy against subsequent amounts owed to Marina, or if no further amounts are owed under
this Agreement, then Marina shall pay ProNAi the amount of the discrepancy within [***] days after being notified thereof.

 ARTICLE 6 
 INTELLECTUAL PROPERTY 
 6.1 Intellectual
Property Ownership. 
 (a) Any information, know-how, data, results, and inventions, and any associated intellectual
property, that is made, discovered, created, invented or generated by ProNAi or its Affiliate in any activities or work under this Agreement shall be owned by ProNAi. 
 (b) Any information, know-how, data, results, and inventions, and any associated intellectual property, that 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. 
 (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

 [CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION,
WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH AN ASTERISK [***], HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.] 
  

 
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

 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 

  
 17 

 [CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS DOCUMENT. EACH SUCH PORTION,
WHICH HAS BEEN OMITTED HEREIN AND REPLACED WITH AN ASTERISK [***], HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.] 
  

 
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. 

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.

 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. 
 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 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

(b) Termination for Bankruptcy/Insolvency. A Party may immediately terminate this Agreement in its entirety, or on a
country-by-country basis, on written notice in the event (each, a “Financial Event”) any of the following occurs with respect to the other Party (the “Bankrupt Party”): (a) such Bankrupt Party
files a petition in bankruptcy or makes a general assignment for the benefit of creditors or otherwise acknowledges in writing insolvency, or is adjudged bankrupt, and such Bankrupt Party (i) fails to assume this Agreement in any such
bankruptcy proceeding within thirty (30) days after filing or (ii) assumes and assigns this Agreement to a Third Party; (b) such Bankrupt Party goes into or is placed in a process of complete liquidation; (c) a trustee or

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:
(i) it is dismissed, (ii) it is bonded in a manner reasonably satisfactory to the other Party, or (iii) it is discharged. 
 (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

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) 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. 
 About Marina Biotech, Inc. 
 Marina Biotech is a biotechnology company focused on the development and commercialization of oligonucleotide-based therapeutics utilizing multiple mechanisms of action including RNA interference (RNAi)
and messenger RNA translational blocking. The Marina Biotech pipeline currently includes a clinical program in Familial Adenomatous Polyposis (a precancerous syndrome) and two preclinical programs — in bladder cancer and malignant ascites.
Marina Biotech entered into an exclusive agreement with The Debiopharm Group for the development and commercialization of the bladder cancer program. In addition, Marina Biotech has entered into an agreement with Mirna Therapeutics to license Marina
Biotech’s SMARTICLES® technology for the delivery of microRNA mimics. Marina Biotech’s goal is to
improve human health through the development of RNAi- and oligonucleotide-based compounds and drug delivery technologies that together provide superior therapeutic options for patients. Additional information about Marina Biotech is available at
