The royalty obligation under Section 4.3 shall accrue upon the sales of a Protiva Product in each particular country in the Territory, commencing upon First Commercial Sale after Regulatory Approval of the Protiva Product in such country and except as otherwise provided under Subsection 4.3(b), such obligation shall end upon the expiration of the Royalty Term applicable to such Protiva Product in such country. All such royalty payments are nonrefundable and non-creditable and shall be due within [...***...] after the end of each Calendar Quarter and are payable in immediately available funds.

Protiva shall notify Marina in writing promptly upon the First Commercial Sale of each Protiva Product in each country and thereafter Protiva shall furnish Marina with a written report (the “Royalties Report”) for each completed Calendar Quarter showing, on a country-by-country basis, according to the volume of units of Protiva Products sold in each such country (by SKU) during the reporting period (whether Protiva Product is sold by Protiva or its Affiliates or Sublicensees):

^* *** Confidential Treatment Requested

(a)	the gross invoiced sales of the Protiva 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 such Net Sales; 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, Protiva shall report only the net sales numbers (using the definition for such term in the applicable Sublicense) as reported by the Sublicensee, if such Sublicensee does not report gross invoiced sales numbers).

With respect to sales of Protiva Products invoiced in US dollars, the gross invoiced sales, Net Sales and royalties payable shall be expressed in the Royalties Report in US Dollars. With respect to sales of Protiva Products 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 royalties 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.

4.7Currency 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, Protiva shall have the right and option upon written notice to Marina to make (or to cause its Sublicensee 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.

4.8Taxes.

In the event that laws, rules or regulations require Protiva to withhold taxes with respect to any payment to be made by Protiva to Marina pursuant to this Agreement, Protiva will notify Marina of such withholding requirement prior to making the payment to Marina. Any and all taxes levied by a proper taxing authority required to be withheld by Protiva or its Sublicensees on account of royalties accruing to Marina under this Agreement may be deducted from such royalty payment provided that (a) such amount is promptly paid for and on behalf of Marina to the appropriate tax authorities, and (b) Protiva furnishes Marina with official tax receipts or other appropriate evidence of payment issued by the appropriate tax authorities. Protiva shall 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.

4.9Late Payments.

All fees and royalties not received by Marina when due under this Agreement shall bear interest from the date they were due until the date they are paid at a rate equal to the then current 30-day United States dollar LIBOR rate plus two percent per annum or the maximum rate permitted by law, whichever is less. Notwithstanding anything to the contrary in this Agreement, Protiva

shall have no obligation to pay royalties to Marina pursuant to Section 4.3 until Protiva actually receives revenue from Net Sales.

4.10Audit.

Protiva and its Affiliates shall keep complete and accurate records of the underlying revenue and expense data relating to the calculations of Net Sales, Sublicensing Revenue and payments required under this Agreement. Marina shall have the right, at its own expense and no more than once per Calendar Year, to have an independent, certified public accountant, selected by Marina and reasonably acceptable to Protiva, 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. Protiva 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, Protiva shall pay the amount of the discrepancy in Marina’s favor within [...***...] after being notified thereof. Marina shall pay the full cost of the inspection unless the discrepancy is greater than [...***...], in which case Protiva shall pay to Marina the actual cost charged by such accountant for such inspection. If such audit shows a discrepancy in Protiva’s favor, then Protiva 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 Protiva the amount of the discrepancy within [...***...] after being notified thereof.

Article 11 INDEMNIFICATION; LIABILITY

11.1Indemnification by Marina.

Marina shall defend, indemnify, and hold Protiva, its Affiliates, and their respective officers, directors, employees and agents, and all successors and assigns of any of the foregoing (“Protiva Indemnitees”) harmless from and against any Claims against them to the extent arising or resulting from:

(a)	the gross negligence or willful misconduct of Marina or any of its Affiliates; or

(b)	the breach of any of the covenants, representations or warranties made by Marina to Protiva under this Agreement;

provided, however, that Marina shall not be obliged to so indemnify, defend and hold harmless the Protiva Indemnitees for any Claims to the extent that Protiva has an obligation to indemnify Marina Indemnitees pursuant to Section 11.2 or to the extent that such Claims arise from the breach, gross negligence or willful misconduct of Protiva or a Protiva Indemnitee.

11.2Indemnification by Protiva.

Protiva shall defend, indemnify, and hold Marina, its Affiliates, and their respective officers, directors, employees and agents, and all successors and assigns of any of the foregoing (“Marina Indemnitees”) harmless from and against any Claims against them to the extent arising or resulting from:

(a)	the gross negligence or willful misconduct of Protiva or any of its Affiliates or Sublicensees;

(b)	the breach of any of the covenants, representations or warranties made by Protiva to Marina under this Agreement;

(c)

the exercise or practice by Protiva, its Affiliates or Sublicensees of the license granted to Protiva under Section 2.1 (excluding any such Claim that alleges that the exercise or practice of the Marina Technology infringes a Patent or misappropriates other Intellectual Property Rights of a Third Party); or

(d)	the development, manufacture or commercialization of any Protiva Product by or for Protiva, its Affiliates or Sublicensees;

provided, however, that Protiva shall not be obliged to so indemnify, defend and hold harmless the Marina Indemnitees for any Claims to the extent that Marina has an obligation to indemnify Protiva Indemnitees pursuant to Section 11.l or to the extent that such Claims arise from the breach, gross negligence or willful misconduct of Marina or a Marina Indemnitee.

11.3Indemnification Procedure.

(a)	For the avoidance of doubt, all indemnification claims in respect of a Protiva Indemnitee or Marina Indemnitee shall be made solely by Protiva or Marina, respectively, on behalf of the Protiva Indemnitee or Marina Indemnitee, as the case maybe.

(b)

A Party seeking indemnification hereunder (“Indemnified Party”) shall notify the other Party (“Indemnifying Party”) in writing reasonably promptly after the assertion against the Indemnified Party of any Claim or fact in respect of which the Indemnified Party intends to base a claim for indemnification hereunder (“Indemnification Claim Notice”), but the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation or liability that it may have to the Indemnified Party, except to the extent that the Indemnifying Party demonstrates that its ability to defend or resolve such Claim is adversely affected thereby. The Indemnification Claim Notice shall contain a description of the claim and the nature and amount of the Claim (to the extent that the nature and amount of such Claim is known at such time). Upon the request of the Indemnifying Party, the Indemnified Party shall furnish promptly to the Indemnifying Party copies of all correspondence, communications and official documents (including court documents) received or sent in respect of such Claim.

(c)

Subject to the provisions of Subsection 11.3(d), the Indemnifying Party shall, within ^*[...***...] after receipt of the Indemnification Claim Notice, advise the Indemnified Party whether it is assuming the defense and handling of such Claim, at the Indemnifying Party’s sole expense. The assumption of the defense of a Claim by the Indemnifying Party shall not be construed as acknowledgement that the Indemnifying Party is liable to indemnify any indemnitee in respect of the Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against any Indemnified Party’s claim for indemnification. In the event that it is ultimately decided that the Indemnifying Party is not obligated to indemnify or hold an indemnitee harmless from and against the Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all reasonable

^* *** Confidential Treatment Requested

costs and expenses (including attorneys’ fees and costs of suit) incurred by the Indemnifying Party in its defense of the Claim.

(d)	Upon assumption of the defense of a Claim by the Indemnifying Party:

(i)

the Indemnifying Party shall have the right to and shall assume sole control and responsibility for dealing with the Claim;

(ii)

the Indemnifying Party may, at its own cost, appoint as counsel in connection with conducting the defense and handling of such Claim any law firm or counsel reasonably selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party (such consent not to be unreasonably withheld or delayed);

(iii)

the Indemnifying Party shall keep the Indemnified Party informed of the status of such Claim; and

(iv)

the Indemnifying Party shall have the right to settle the Claim on any terms the Indemnifying Party chooses; provided, however, that it shall not, without the prior written consent of the Indemnified Party, agree to a settlement of any Claim which could lead to liability for or create any financial or other obligation or restriction on the Indemnified Party (or abrogate the license rights granted under this Agreement) for which the Indemnified Party is not entitled to indemnification hereunder or which admits any wrongdoing or responsibility for the Claim on behalf of the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party at the Indemnifying Party’s expense. In particular, the Indemnified Party shall furnish such records, information and testimony, provide witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith; subject to the right of the Indemnified Party to obtain confidentiality protection in connection therewith consistent with the confidentiality provisions of this Agreement. Such cooperation shall include access during normal business hours by the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Claim, and making the Indemnified Party, the Protiva Indemnitees or Marina Indemnitees, as the case may be, and its and their employees and agents available on a mutually convenient basis to provide additional information and explanation of any records or information provided. The Indemnified Party shall be entitled to participate in, but not control, the defense of such Claim with its own counsel and at its own expense; provided, however, that if the litigants in any such action include both the Indemnified Party and the Indemnifying Party and legal counsel for the Indemnified Party shall have reasonably concluded in a written legal opinion delivered to the Indemnifying Party that, by reason of certain bona fide defenses available to the Indemnified Party which are different from or additional to those available to the Indemnifying Party, the interests of the Indemnified Party materially conflict with the interests of the Indemnifying Party such that it would be unethical under applicable rules relating to attorney conflicts of interest for the Indemnifying Party and such Indemnified Party to be represented by the same counsel with respect to such defense, the Indemnified Party shall have the right to select one separate counsel and to assert such legal defenses, with the reasonable expenses and fees of such separate counsel to be reimbursed by the Indemnifying Party as and when incurred.

(e)

If the Indemnifying Party fails to assume or conduct the defense and handling of any Claim in good faith as provided Subsections 11.3(c) and 11.3(d), the Indemnified Party may, at the Indemnifying Party’s expense, select counsel reasonably acceptable to the Indemnifying Party (such consent not to be unreasonably withheld or delayed) in connection with conducting the defense and handling of such Claim and defend or handle such Claim in such manner as it may deem appropriate; provided, that the foregoing shall not be construed as a limitation on the Indemnified Party’s right to claim that the Indemnifying Party has breached its obligations pursuant to this Article 11. In such event, the Indemnified Party shall keep the Indemnifying Party timely apprised of the status of such Claim and the Indemnified Party shall have the right to settle the Claim on any terms the Indemnified Party chooses; provided, however, that the Indemnified Party shall not, without the prior written consent of the Indemnifying Party, agree to a settlement of any Claim which could lead to liability or create any financial or other obligation on the part of the Indemnifying Party, other than its liability for indemnification of the Indemnified Party as provided in this Article 11, or which admits any wrongdoing or responsibility for the claim on behalf of the Indemnifying Party.

11.4Mitigation of Loss.

Each Indemnified Party will take and will procure that its Affiliates take all such reasonable steps and action as are necessary or as the Indemnifying Party may reasonably require in order to mitigate any Claims (or potential losses or damages) under this Article 11. Nothing in this Agreement shall or shall be deemed to relieve any Party of any common law or other duty to mitigate any losses incurred by it.

11.5Insurance.

Protiva shall, at its own expense, procure and maintain during the Term and for a period of ^*[...***...] 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.

11.6Special, Indirect and Other Losses.

NEITHER PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE IN CONTRACT, TORT, NEGLIGENCE BREACH OF STATUTORY DUTY OR OTHERWISE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES OR FOR ANY ECONOMIC LOSS OR LOSS OF PROFITS SUFFERED BY THE OTHER PARTY, EXCEPT TO THE EXTENT ANY SUCH DAMAGES ARE REQUIRED TO BE PAID TO A THIRD PARTY AS PART OF A CLAIM FOR WHICH A PARTY PROVIDES INDEMNIFICATION UNDER THIS Article 11.

11.7No Exclusion.

Neither Party excludes any liability for death or personal bodily injury caused by its negligence or the negligence of its Affiliates or, in the case of Protiva, its Sublicensees, or their respective employees, agents or sub-contractors.

Tekmira Acquires Worldwide License to Novel RNAi Technology

Tekmira and Marina Biotech Enter into License Agreement for UNA Technology

November 29 0000

Xxxxxxxxx, XX — Tekmira Pharmaceuticals Corporation (Nasdaq: TKMR, TSX: TKM), a leading developer of RNA interference (RNAi) therapeutics, announced today that it will obtain a worldwide, non-exclusive license to a novel RNAi payload technology called Unlocked Nucleobase Analog (UNA) from Marina Biotech, Inc. (OTCQX:MRNA) for the development of RNAi therapeutics.

UNA technology can be used in the development of RNAi therapeutics, which treat disease by silencing specific disease causing genes. UNAs can be incorporated into RNAi drugs and have the potential to improve them by increasing their stability and reducing off-target effects.

“Our license to Marina’s UNA technology expands and diversifies our foundation of technologies that enable us to develop RNAi therapeutics. With Tekmira’s leading LNP delivery technology, a strong balance sheet, and access to multiple RNAi payload technologies, we are well positioned to aggressively advance multiple products into human clinical trials,” said Xx. Xxxx X. Xxxxxx, Tekmira’s President and CEO.

“We intend to leverage our expertise in LNP delivery and our broad understanding of therapeutic RNA payload design to optimize the use of UNA in our development pipeline, as well as provide pharmaceutical partners the opportunity to license UNAs combined with our LNP delivery technology to develop RNAi therapeutics,” added Xx. Xxxxxx.

Under the license agreement, Tekmira will receive a worldwide, non-exclusive rights to MARINA Biotech’s UNA technology for the development of RNAi therapeutic products, and MARINA will receive an upfront payment plus milestone and royalty payments on products developed by Tekmira that use UNA technology. Financial terms of the license agreement were not disclosed.

Unlocked Nucleobase Analogs (UNA) are acyclic ribonucleoside analogs in which the bond between C2’ and C3’ atoms is broken. This change in sugar structure renders this nucleoside analog very flexible. This characteristic is in contrast to the widely used locked nucleosides that lock the sugar conformation by a bridged bond between C2’ and C4’ atoms. The flexible nature of UNA reduces the binding affinity between two strands of an RNAi drug and gives unique characteristics to its genes silencing abilities. MARINA Biotech has demonstrated that UNA has the potential to improve RNAi therapeutics by increasing stability and reducing sense and antisense mediated off-target effects while retaining potency.

About RNAi and Tekmira’s LNP

RNAi therapeutics have the potential to treat a broad number of human diseases by “silencing” disease causing genes. The discoverers of RNAi, a gene silencing mechanism used by all cells, were awarded the 2006 Nobel Prize for Physiology or Medicine. RNAi therapeutics, such as “siRNAs,” require delivery technology to be effective systemically. Tekmira believes its LNP technology represents the most widely adopted delivery technology for the systemic delivery of RNAi therapeutics. Tekmira’s LNP platform is being utilized in multiple clinical trials by both Tekmira and its partners. Tekmira’s LNP technology (formerly referred to as stable nucleic acid-lipid particles or SNALP) encapsulates siRNAs with high

efficiency in uniform lipid nanoparticles that are effective in delivering RNAi therapeutics to disease sites in numerous preclinical models. Tekmira’s LNP formulations are manufactured by a proprietary method which is robust, scalable and highly reproducible, and LNP-based products have been reviewed by multiple FDA divisions for use in clinical trials. LNP formulations comprise several lipid components that can be adjusted to suit the specific application.

Marina Biotech Announces Worldwide Non-Exclusive Licensing Agreement
for Nucleic Acid Chemistry to Tekmira Pharmaceuticals

Bothell, WA, November 29, 2012 - Marina Biotech, Inc. (OTCQX:MRNA), a leading oligonucleotide based drug discovery and development company, announced today that it has entered into a license agreement with Tekmira Pharmaceuticals Corporation (Nasdaq: TKMR, TSX: TKM), where Marina will provide Tekmira a worldwide, non-exclusive license to Marina Biotech’s Unlocked Nucleobase Analog (UNA) technology for the development of RNA interference therapeutics. Tekmira will have full responsibility for the development and commercialization of any products arising under the Agreement. Under terms of the Agreement, Marina Biotech will receive an upfront payment plus milestone and royalty payments on products developed by Tekmira that use UNA technology. Further terms of the Agreement were not disclosed.

“We are pleased to enter into this agreement with Tekmira, a leader in the development of RNAi-based therapeutics,” stated J. Xxxxxxx Xxxxxx, President and Chief Executive Officer of Marina Biotech. “Marina Biotech’s UNA technology is quite novel. Besides providing drug-like properties to an RNAi drug, UNAs also eliminate passenger strand activity as well as reduce guide strand mediated microRNA like off-target activity. The result is that UNAs are able to significantly increase target specificity of an RNAi compound to its gene target. We look forward to a continued relationship with the great team at Tekmira.”

About Unlocked Nucleobase Analogs

Unlocked Nucleobase Analogs (UNA) are acyclic ribonucleoside analogs in which the bond between C2’ and C3’ atoms is broken. This change in sugar structure renders this nucleoside analog very flexible. This characteristic is in sharp contrast to the widely used locked nucleosides that lock the sugar conformation by a bridged bond between C2’ and C4’ atoms. The flexible nature of UNA reduces the binding affinity between two strands of an RNAi drug and gives unique characteristics to its genes silencing abilities. Marina Biotech has demonstrated that UNA has the potential to improve RNAi therapeutics by increasing stability and reducing sense and antisense mediated off-target effects while retaining potency.
