(or its Affiliate) enters into a sublicense Agreement under which the applicable Sublicensee is granted sublicense rights to Commercialize a Licensed Product, then achievement of any of the above Milestone Events by such Sublicensee, or by MirnaRx or its Affiliate working in collaboration with such Sublicensee under the sublicense agreement, shall not create a Milestone Payment obligation, but instead MirnaRx shall have the obligation to share Sublicense Revenues received under such sublicense agreement as provided in Section 5.6 below.

(b) MirnaRx shall promptly notify Marina Bio 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 [***] of achievement of the applicable Milestone Event.

5.4 Royalties. In part consideration of the license rights granted by Marina Bio under this Agreement, and subject to the provisions of Sections 5.5, MirnaRx shall pay royalties to Marina Bio on sales by MirnaRx or any of its Affiliates of Licensed Products during the Royalty Term, as follows:

(a) 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, MirnaRx shall pay to Marina Bio royalties equal to [***]% of the Net Sales revenue recognized by MirnaRx or any of its Affiliates from such sales;

(b) For sales of License Product in country(ies) where either (i) there is no Valid Claim in an issued Licensed Patent that would be infringed, absent the license granted in Section 2.1, by such sale of the Licensed Product, or (b) there are sales of Generic Products during the same royalty period as such sales of Licensed Product, then MirnaRx shall pay to Marina Bio royalties equal to [***]% of the Net Sales revenue recognized by MirnaRx or any of its Affiliates from such Licensed Product sales.

5.5 Anti-Stacking Provisions. If MirnaRx, or its Affiliate owes to one or more Third Parties, under license agreement(s) granting .MirnaRx (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 the Licensed Product, royalties or similar payments on sales of such Licensed Products, then MirnaRx may reduce the royalties owed to Marina Bio 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 MirnaRx shall not reduce any particular royalty payment to Marina Bio by more than [***]% of

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

the amount otherwise owed under the royalty provisions of Section 5.4 for the applicable royalty period.

5.6 Sublicense Fees. In part consideration of the license rights granted by Marina Bio under this Agreement and the right to sublicense such licenses. MirnaRx shall pay to Marina Bio an amount (“Sublicense Fees”) equal to a percentage of any Sublicensing Revenue received by MirnaRx (or its Affiliate) from any Sublicensee based on the grant to such Sublicensee of sublicense rights under MirnaRx’s license rights under the Licensed Patents. Such percentage shall be determined based on the development stage of the applicable Licensed Product (that is covered by the sublicense) at the time that the particular sublicense agreement is executed by the parties thereto, as follows:

[***] |  | Percentage of Sublicense Revenue |
[***] |  | [***]% |
[***] |  | [***]% |
[***] |  | [***]% |
[***] |  | [***]% |
[***] |  | [***]% |

If, as to a particular Licensed Product being developed by a Sublicensee, such Sublicensee first achieves, with respect to such Licensed Product, one of the Milestone Events in the milestone table in Section 5.3(a) above, then in no event will the cumulative amount (the “Cumulative Sublicense Fees”, as of the applicable date) of Sublicense Fees paid to Marina Bio by MirnaRx. under this Section 5.6, by the date [***] after the date that such Milestone Event is achieved, with. respect to Sublicense Revenues received by MirnaRx from such Sublicensee, be less than the cumulative amount (the “Milestone Payment Sum”, as of the applicable date) of the Milestone Payments that would have been due under Section 5.3(a) by such date, for all Milestone Events achieved by such Sublicensee (as of such date), had MirnaRx achieved such Milestone Events. If, as to a Sublicensee that first achieves a particular Milestone Event for the applicable Licensed Product sublicensed to such Sublicensee, the Cumulative Sublicense Fees paid by MirnaRx to Marina Bio based on Sublicense Revenues received from such Sublicensee, by the date that is [***] after the date when such Milestone Event is achieved, is less than the Milestone Payment Sum effective as of such date, then MirnaRx will by such date also pay to Marina Bio the amount of such difference (such amount, the “True-Up Payment” as to the applicable Milestone Event achieved by such Sublicensee). An example of the calculation of such amounts and the determination of such difference (if any) is given in Appendix B of this Agreement. For clarity, any such True-Up Payment shall be deemed a Sublicensee Fee payment for all purposes of this Agreement. Further, if in the sublicense agreement between MirnaRx and a particular Sublicensee, the definition of “Major Markets” (or equivalent definition) is different from the definition in Section 1.27 of this Agreement, then the definition in such sublicense agreement will be used with respect to the achievement of the Milestone Event in subclause (i)(4) of the milestone table in Section 5.3(a) above, for the purpose of determining

[***] Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

whether any “True-Up Payment” is owed by MirnaRx based on the Sublicensee achieving Regulatory Approval of the applicable Licensed Product in a Major Market.

5.7 Payment of Royalty and Sublicense Fee Obligations. 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 [***] of the end of each calendar quarter and are payable in immediately available funds. The Sublicense Fees owed under Section 5.6 shall be paid, with respect to particular Sublicense Revenue received by MirnaRx., within [***] of MirnaRx’s receipt of the applicable revenues, and are payable in immediately available funds. MirnaRx shall notify Marina Bio in writing promptly upon the first commercial sale of Licensed Product in each country and thereafter MirnaRx shall furnish Marina Bio 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 Product is sold by MirnaRx or its Affiliates or Sublicensees): (a) the gross invoiced sales of the 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 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, MirnaRx 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.

5.8 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, MirnaRx shall have the right anti option upon written notice to Marina Bio to make such payments by depositing the amount thereof in local currency to Marina Bio’s account (or such other designated nominee by Marina Bin) in a bank or depository in such country.

5.9 Taxes. In the event that laws, rules or regulations require MirnaRx to withhold taxes with respect to any payment to be made by MirnaRx to Marina Bio pursuant to this Agreement, MirnaRx will notify Marina Bio of such withholding requirement prior to making the payment to Marina Bio 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 Bio, including the provision of such documentation as may be required by a tax authority, as may be reasonably necessary in Marina Bio’s efforts to claim an exemption from or reduction of such taxes.

5.10 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.

5.11 Audit. MirnaRx 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 Bio shall have the right, at its own expense and no more than [***], to have an independent, certified public accountant, selected by Marina Bio and reasonably acceptable to MirnaRx, 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 [***] period. No calendar quarter may be audited more than one time. MirnaRx shall receive a copy of each audit report promptly from Marina Bio. Should the inspection lead to the discovery of a discrepancy to Marina Bio’s detriment, MirnaRx shall pay the amount of the discrepancy in Marina Bio’s favor within [***] after being notified thereof. Marina Bio shall pay the full cost of the inspection unless the discrepancy is greater than [***] percent ([***]%), in which case MirnaRx shall pay to Marina Bio the actual cost charged by such accountant for such inspection. If such audit shows a discrepancy in MirnaRx’s favor, then MirnaRx may credit the amount of such discrepancy against subsequent amounts owed to Marina Bio, or if no further amounts are owed under this Agreement, then Marina Bio shall pay MirnaRx the amount of the discrepancy within [***] after being notified thereof.

EXAMPLE OF CALCULATION OF CUMULATIVE SUBLICENSE FEES

The following is an example of the calculation of payment of Sublicense Fees under Section 5.6, under a hypothetical sublicense agreement under this Agreement:

Hypothetical: Assume that MirnaRx grants a sublicense to a Sublicensee to develop and commercialize its Licensed Product “[***]” when such product has [***] but before [***]. Assume further that under such sublicense agreement, the Sublicensee pays MirnaRx an upfront sublicense fee of $[***], pays no milestone payment on [***], and pays MirnaRx the following milestone payments with respect to such sublicense grant on achieving the listed milestone events: (a) $[***] on [***], $[***] on [***], and $[***] on [***].

Based on the foregoing assumptions (and understanding that this is just a hypothetical example and provides no precedence or assumption of the terms of an actual sublicense deal), MirnaRx would pay to Marina Bio Sublicense Fees in the following amounts and times under such hypothetical:

· Sublicense Fee of $[***], by the date [***] after the upfront sublicense fee is paid ([***]% of the upfront)

· Sublicense Fee of $[***], by the date [***] after the [***] milestone for [***] is achieved by Sublicensee (the “True-Up Payment” of $[***] equal to the difference between the “[***]” milestone payment amount under Section 5.3(a)(i)(2) and the “Cumulative Sublicense Fees” paid to Marina Bio up to that point for such product)

· Sublicense Fee of $[***], by the date [***] after [***] (equal to [***]% of the milestone payment made by the Sublicensee, plus a “True-up Payment” of $[***], such that the Cumulative Sublicensee Fees as of such date (such cumulative amount equal to $[***] after such True-Up Payment) equals the Milestone Payment Sum as of such date (which is $[***], including the milestone payment amount under Section 5.3(a)(i)(3) for achieving a [***] milestone)

· Sublicense Fee of $[***] by the date [***] after [***] ([***]% of the milestone payment paid by Sublicensee to MirnaRx for [***])

· Sublicense Fee of $[***], by the date [***] after [***] (equal to [***]% of the milestone payment by the Sublicensee, plus a “True-up Payment” of $[***], such that the Cumulative Sublicensee Fees as of such date (such cumulative amount equal to $[***] after such True-Up Payment) equals the Milestone Payment Sum as of such date (which is $[***], including the milestone payment amount under Section 5:3(a)(i)(4) for [***])

JOINT PRESS RELEASE

Marina Biotech and Mirna Therapeutics Announce License

Agreement for the Development of microRNA-based Therapeutics

- Mirna Therapeutics will develop oncology-focused compounds utilizing their proprietary microRNAs combined with Marina Biotech’s novel SMARTICLES® liposomal delivery technology -

Bothell, WA and Austin, TX December 23, 2011 — Marina Biotech, Inc. (Nasdaq: MRNA), a leading oligonucleotide-based drug discovery and development company, and Mirna Therapeutics, Inc. (Mirna), a privately-held biotechnology company pioneering microRNA (miRNA) replacement therapy for cancer, announced today that they have entered into a license agreement regarding the development and commercialization of microRNA-based therapeutics utilizing Mirna’s proprietary microRNAs and Marina Biotech’s novel SMARTICLES liposomal delivery technology. Mirna will have full responsibility for the development and commercialization of any products arising under the Agreement and Marina Biotech will support pre-clinical and process development efforts. Under terms of the Agreement, Marina Biotech could receive up to $63 million in total upfront, clinical and commercialization milestone payments, as well as royalties on sales, based on the successful outcome of the collaboration. Further terms of the Agreement were not disclosed.

“Given the challenge of effectively delivering oligonucleotides to target tissues, we devoted considerable effort to identifying an optimal delivery technology that would allow for systemic administration of our potent miRNA tumor suppressors and which is already in clinical testing,” said Paul Lammers, M.D., M.Sc., President and CEO of Mirna Therapeutics. “With the dramatic in vivo results achieved with our miRNA. mimics, we believe the SMARTICLES technology solves the delivery challenge for us, and we are now looking forward to bringing our miRNA mimics into the clinic in the next 18 months as promising targeted cancer therapeutics.

“We are extremely pleased to have entered into this relationship with a company as well respected in the area of microRNA-based therapeutics as Mirna Therapeutics,” stated J. Michael French, President and CEO of Marina Biotech. “We are excited to see the continued advancement of oligonucleotide-based therapeutics and to be able to provide a technology capable of effectively delivering, in this case, systemically administered miRNA mimetics. We look forward to the rapid advancement. of Mirna. Therapeutics’ clinical pipeline and the opportunity to bring novel therapeutics to patients in need.”

In a recent poster entitled “The Development of a miRNA-based Therapeutic Candidate for Hepatocellular Carcinoma,” presented at the November, 2011 AACR-.NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in San Francisco, CA, Mirna scientists showed that mimics of five tumor suppressor miRNAs, including miR-34 and let-7, all significantly inhibited the growth of liver tumors compared to animals treated with formulated negative control miRNAs. The five miRNA mimics were complexed. with Marina

Biotech’s SMARTICLES delivery formulation and injected into NOD/SCID mice with orthotopically grown Hep3B human liver cancer xenografts.

The companies will present their respective science and technologies at the upcoming Biotech Showcase TM 2012, January 9-11, 2012 at the Parc 55 Wyndham San Francisco - Union Square at 55 Cyril Magnin Street, San Francisco, CA. Mirna Therapeutics will present on Monday, 9 January at 3:00 pm and Marina Biotech will present on Tuesday, 10 January at 2:30 pm.
