NOW THEREFORE, in consideration of the foregoing premises, the mutual promises and covenants of the Parties hereinafter set forth, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, do hereby agree as follows.

1.1. Amendment of License Agreement. In accordance with Section 12.1 of the License Agreement, the Parties hereby agree to amend the License Agreement, effective as of the Amendment Effective Date, in accordance with the remainder of this Section 1.

1.2. Section 1.48 of the License Agreement shall be amended and restated in its entirety with the following:

1.48 “Selected MirnaRx Compound” means: (a) the MirnaRx Compound known as miR-34 (the sequence of which is set forth in the Side Letter); or (b) any other MirnaRx Compound that MirnaRx selects, as provided in Section 2.6, to combine with the Marina Bio Technology and to develop (or have developed) as a Licensed Product, and including, for any such Selected MirnaRx Compound, any other MirnaRx Compound that

has at least [***] sequence homology with such Selected MirnaRx Compound, and for each of (a) and (b) including without limitation the compounds listed on Appendix D.

1.3. Section 5.2 of the License Agreement shall be amended and restated in its entirety with the following:

5.2 Selection Fee Payments:

(a) As permitted by Section 2.6, in addition to miR-34, MirnaRx has selected three (3) Option Compounds that are listed on Appendix D to be Selected MirnaRx Compounds. In partial consideration of the license rights granted by Marina Bio under this Agreement, and for the right to develop and commercialize such additional Selected MirnaRx Compounds, MirnaRx shall pay Marina Bio [***] for the designation of such [***] as Selected MirnaRx Compounds equal to [***], which amount shall be paid in full on or before December 27, 2013

(b) With respect to any new MirnaRx Compound that is selected by MirnaRx as a Selected MirnaRx Compound in accordance with Section 2.6 (including without limitation any Option Compound not listed on Appendix D), then MirnaRx shall pay Marina Bio an additional compound selection fee of [***], such amount to be paid as follows: (i) with respect to any Option Compound (other than those listed on Appendix D) that is selected by MirnaRx as a Selected MirnaRx Compound in accordance with Section 2.6, (i) [***] of such amount shall be paid within [***] of the date that MirnaRx selects the Selected MirnaRx Compound under Section 2.6, and (ii) the balance [***] will be paid [***], and (b) with respect to any Selected MirnaRx Compounds that are not Option Compounds when selected by MirnaRx under Section 2.6, the total amount of [***] for such Selected MirnaRx Compound shall be paid within [***] of the date that MirnaRx selects the Selected MirnaRx Compound under Section 2.6. All such selection fees shall be in addition to any amounts due based on sublicensing Revenue received by MirnaRx (if any) for sublicensing a Licensed Product containing the applicable Selected MirnaRx Compound, as set forth in Section 5.6 below.

1.4. A new Appendix D shall be added to the License Agreement entitled “Selected MirnaRx Compounds”, which shall read in its entirety as follows:

miR-34

[***]

1.5. Simultaneous with the execution of this Amendment, MirnaRx shall provide to Marina Bio the sequences of each of the Selected MirnaRx Compounds listed an Appendix D in a separate side letter (the “Amendment Side Letter”). The Amendment Side Letter shall also set forth the sequences of the remaining Option Compounds that have not been designated by MirnaRx as Selected MirnaRx Compounds as of the Amendment Effective Date.

1.6. Section 5.3 shall be amended and restated in its entirety with the following:

5.3 Milestone Payments.

(a) In partial consideration of the license rights granted by Marina Bio under this Agreement, MirnaRx shall pay to Marina Bio a milestone payment upon the first achievement by MirnaRx (independently of work done by or in collaboration with a Sublicensee) of the applicable milestone event set forth in the table below, such payments to be in the listed amounts for the applicable Milestone Event:

Milestone Event		Milestone Payment
(i) For each Licensed Product:
[***]		[***]
(ii) For each Additional Indication for the Licensed Product, up to total of [***] Additional Indications:
(1) [***]		[***]

(b) 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, except that [***]. 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 $6,000,000 under subclause (i) of the above table and $10,000,000 in total. For additional clarity, if MirnaRx (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.

(c) Notwithstanding Sections 5.3(a) and 5.3(b) and the milestone table above, (i) no Milestone Payment for achievement of [***] of the milestone table above, and (ii) no

Milestone Payments for [***] of the milestone table above, shall be payable with respect to any Licensed Product containing or incorporating miR-34. For clarity, Sections 5.3(a) and 5.3(b) and the milestone table above shall apply in full to all Licensed Products other than any Licensed Product containing or incorporating miR-34, unless the Parties mutually agree otherwise in writing.

1.7. The Parties acknowledge and agree that as of the Amendment Effective Date, the Milestone Payment for the achievement of the Milestone Event [***] of the milestone table above has been paid in full by MirnaRx [***].

1.8. Section 5.4 shall be amended and restated in its entirety with the following:

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 Licensed 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, provided that solely with respect to any Licensed Product containing or incorporating miR-34, no royalty shall be payable by MirnaRx with respect to sales in any country.

(b) For sales of Licensed 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, provided that solely with respect to any Licensed Product containing or incorporating miR-34, no royalty shall be payable by MirnaRx with respect to sales in any country.

1.9. Section 12.1 shall be amended and restated in its entirety with the following:

12.1 Entire Agreement; Amendment. This Agreement, including the appendices, and the Side Letter, constitutes the entire agreement between the Parties (or their Affiliates) related to the subject matter hereof.
