In the event of a Change of Control of Protiva or Tekmira with a Principal Competitor, the Diligence Buyout Payment and the Commercial Milestone Payment under the PadCo-Protiva License and Services Agreement (if and when either is paid or payable under the terms of such agreement) shall be reduced by [Redacted – percentage]. Such amounts may be further reduced in accordance with Section 3(f) above.

Protiva’s delivery of the Data Package, whether the Company has met all requirements of Option Insect Phase C Completion Criteria and Option Plant Phase C Completion Criteria; and (viii) attend to such other matters as may be directed to the JRC by the Parties or under the terms of any Transaction Agreement. Each of the Parties shall provide the JRC with copies of all substantive communications (including a copy of the patent application as filed, and copies of all communications from the relevant patent office, and responses thereto) in connection with each patent application that is a Joint Project Patent and shall provide the JRC with periodic updates in respect of the status of any pending application for a Joint Project Patent; the members of the JRC shall review and comment on all drafts of Joint Project Patents. In the event there is a dispute among the members of the JRC regarding any matter to be handled by the JRC, e.g., in the event the members of the JRC are unable to reach a unanimous decision regarding such matter within a reasonable time (wherein such reasonable time may be determined by any one member of the JRC), then such member or members may initiate the appropriate dispute resolution process (as described below) by written notice to the other members of the JRC and such other persons who will be involved in such dispute resolution process (as described below). The processes for resolving such disputes are as follows:

(i) Milestone and Technology Transfer Disputes. In the event of a dispute relating to whether certain Milestones have been met or whether the Technology Transfer has been completed in accordance with the Technology Transfer Completion Criteria, the Chief Executive Officer of Protiva and the Vice President of Chemistry of Monsanto shall use commercially reasonable efforts for a period of 20 days (or such longer period as they may mutually agree) to resolve any such dispute. If, at the end of such period (the “Dispute Negotiation Period”), they are unable to resolve such dispute, then the matter shall be resolved in accordance with Section 12(k)(iv).

(ii) Patent Matters Disputes. Any disputes regarding Patent prosecution matters or patent strategies shall be resolved in the manner set forth on Schedule 12(k).

(iii) Infringement Matter Dispute. Any dispute relating to a JRC Joint IP Infringement Matter or JRC Protiva Project Infringement Matter shall be referred to Independent IP Counsel for a recommendation, which recommendation shall be delivered to the Chief Executive Officer of Protiva and the Vice President of Chemistry of Monsanto within 10 days following such referral. During the 10 day period immediately following receipt of Independent IP Counsel’s recommendation, the Chief Executive Officer of Protiva and the Vice President of Chemistry of Monsanto shall use commercially reasonable efforts to resolve such dispute taking into consideration Independent IP Counsel’s recommendation. If, at the end of such period, they are unable to resolve such dispute, then the Parties agree to proceed based on Independent IP Counsel’s recommendation.

(iv) Arbitration. Any dispute relating to (A) whether certain Milestones have been met or whether the Technology Transfer has been completed in accordance with the Technology Transfer Completion Criteria that has not been resolved in accordance with Section 12(k)(i), (B) whether the Company has completed Phase C or (C) the designation of the Independent IP Counsel, shall be settled by arbitration in New York, New York in accordance with the Commercial Arbitration Rules of the American Arbitration Association, and judgment on the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof.

(v) Any Other Dispute. In the event of any other dispute relating to the Research Plan, including any dispute relating to prioritization, direction, or other strategic issues regarding services provided by Protiva pursuant to the PadCo-Protiva License and Services Agreement or services provided by Monsanto pursuant to the Protiva-Monsanto Services Agreement, or any other dispute to be resolved pursuant to the provisions of this Section 12(k)(v), the Chief Executive Officer of Protiva and the Vice President of Chemistry of Monsanto shall use commercially reasonable efforts for a period of 20 days (or such longer period as they may mutually agree) to resolve any such dispute. If, at the end of such period, they are unable to resolve such dispute, then the matter shall be resolved by the Chief Technology Officer of Monsanto; provided, however, that (a) such resolution shall not contravene existing agreements that Protiva is a party to or its business strategies or require the contribution of additional resources of the Company without Protiva’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned and (b) any increase in costs to Protiva as a result of decisions by Monsanto Canada under this Section 12(k)(v) shall be borne by Monsanto Canada.

(l) Disclosure of Protiva Project Compounds. In the event Monsanto Canada requests disclosure of the chemical composition of any Compounds or Formulations Discovered by, Developed by, that come under the Control of, or that are otherwise used by or on behalf of, Protiva or any of its Affiliates under the Research Program or in connection with the provision of Services that are not Joint Project Intellectual Property and that are the Confidential Information of Protiva (each a “Protiva Project Compound”) prior to Closing: (i) Protiva shall disclose the chemical composition of such Protiva Project Compound to the persons then serving as the Monsanto Canada members of the JRC (the “Permitted Recipients”); (ii) the Permitted Recipients shall use such chemical composition information solely to evaluate the merits of filing a Patent application that would require disclosure of such chemical composition information and, for such purpose only, may disclose such chemical composition to such representatives of Monsanto or Monsanto Canada who (A) are bound by non-disclosure obligations with respect to such information at least as restrictive as those contained in Section 7(m) and this Section 12(l) and (B) whose input the Permitted Recipients deem useful for purposes of such evaluation (i.e., disclosure to representatives on a need to know basis only); and (iii) in the event the Permitted Recipients, in their discretion, elect to recommend filing such a Patent application, such recommendation shall be referred to the JRC, to be considered by the JRC in the performance of its duties, as set forth in Section 12(k) and Schedule 12(k). In the event the then Licensee (as defined in the PadCo-Protiva License and Services Agreement) under the PadCo-Protiva License and Services Agreement requests disclosure of the chemical composition of any Protiva Project Compound after Closing: (i) Protiva shall disclose the chemical composition of such Protiva Project Compound to the persons designated by the Licensee; (ii) the Licensee may use and disclose such chemical composition information (which chemical composition information is and shall be Protiva Know-How for purposes of the Transaction Agreements) for the purposes set out in and subject to the terms and conditions of the PadCo-Protiva License and Services Agreement; and (iii) in the event the Licensee, in its discretion, elects to recommend filing a Patent application that would require disclosure of such chemical composition information, such recommendation shall be referred to the JRC, to be

considered by the JRC in the performance of its duties, as set forth in Section 12(k) and Schedule 12(k). Nothing in this Section 12(l) shall be deemed to limit Protiva’s rights to make decisions and/or recommendations regarding the filing or prosecution of Protiva Background Patents or Protiva Project Patent so long as such activities are conducted in a manner Protiva reasonably determines will prevent the disclosure to Monsanto Canada of chemical composition information not requested by Monsanto Canada.

(m) Specific Enforcement. The parties hereto agree that if any of the provisions of this Agreement, were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that, except as otherwise provided herein, the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity, without any requirement to the securing or posting of any bond in connection with such remedy.

(n) No Finder’s Fees. Each party represents that it neither is nor will be obligated for any finder’s fee or commission in connection with this transaction. Monsanto Canada agrees to indemnify and to hold harmless the Company and Protiva from any liability for any commission or compensation in the nature of a finder’s or broker’s fee arising out of this transaction (and the costs and expenses of defending against such liability or asserted liability) for which Monsanto Canada or any of its officers, employees, or representatives is responsible. The Company and Protiva agree to indemnify and hold harmless Monsanto Canada from any liability for any commission or compensation in the nature of a finder’s or broker’s fee arising out of this transaction (and the costs and expenses of defending against such liability or asserted liability) for which the Company or Protiva or any of their respective officers, employees or representatives is responsible.

(o) Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

(p) Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

Tekmira Signs Development Agreement on Delivery Technology For Agricultural Applications


FOR IMMEDIATE RELEASE:		January 13, 0000

Xxxxxxxxx, XX — Tekmira Pharmaceuticals Corporation (Nasdaq: TKMR, TSX: TKM), a leading developer of RNA interference (RNAi) therapeutics, announced today that it has signed an Option Agreement with Monsanto, pursuant to which Monsanto may obtain a license to use Tekmira’s proprietary delivery technology. The transaction will support the application of Tekmira’s proprietary delivery technology and related intellectual property (IP) for use in agriculture. Tekmira noted that the potential value of the transaction could reach up to US$86.2 million following the successful completion of milestones. Tekmira expects to receive a near term payment of net US$16.5 million.

The agreement announced today follows Monsanto’s initial testing of Tekmira’s proprietary delivery technology and the demonstration of initial positive results from use of that technology in the field of agriculture. The companies’ agreement and research collaboration will now focus on the development of new innovative biological solutions for farmers, which have the potential to provide new options for sustainable pest, virus and weed control.

Over the option period, which is expected to be approximately four years, Tekmira will provide lipid formulations to Monsanto’s research and development activities, and Monsanto will make certain payments to Tekmira to maintain its option rights. At any time during the option period, Monsanto may choose to exercise its option, in which case Monsanto will pay to Tekmira an option exercise fee and will receive a worldwide, exclusive right to use Tekmira’s proprietary delivery technology in the field of agriculture. Monsanto may elect to terminate this option at their discretion. Tekmira retains all rights to therapeutics uses of all current IP and IP developed under the agreement.

“Our proprietary delivery technology is enabling the most advanced applications of RNAi therapeutics in the clinic. This new agreement points to the broad applicability of Tekmira’s delivery platform, and underscores the promise of applying this science within the field of agriculture. We are pleased to have this additional validation of our technology,” said Xx. Xxxx X. Xxxxxx, Tekmira’s President and CEO.

“As a core pillar of our business strategy, we continue to seek out a wide range of partnerships where our technology can enable the programs of our collaborators,” added Xx. Xxxxxx.

“We are pleased to partner with Tekmira to explore development of their delivery technologies for the field of agriculture,” said Xx. Xxxxxx X XxXxxxxxx, Vice President of Chemistry Technology for Monsanto Company. “We believe that by collaborating with Tekmira, the company’s research can provide a key enablement to support and expand our BioDirect technology platform.”

Forward-Looking Statements and Information

This news release contains “forward-looking statements” or “forward-looking information” within the meaning of applicable securities laws (collectively, “forward-looking statements”). Forward-looking statements in this news release include statements about Monsanto’s potential worldwide, exclusive right to use Tekmira’s proprietary LNP platform technology in the field of agriculture; the use of Tekmira’s proprietary LNP platform technology and related IP in agriculture applications; the Monsanto option agreement, including the quantum of the potential value, quantum and timing of expected payments, expected duration of the option period and expected focus of research collaboration activities on the development of new innovative biological solutions for farmers; the provision by Tekmira of lipid formulations to Monsanto’s research and development activities and payment by Monsanto to Tekmira to maintain its option rights; and Tekmira’s strategy, future operations, prospects and the plans of management.

With respect to the forward-looking statements contained in this news release, Tekmira has made numerous assumptions regarding, among other things: LNP’s status as a leading RNAi delivery technology; Tekmira’s research and development capabilities and resources; the use of LNP technology by Tekmira’s development partners; and the timing and quantum of payments to be received under contracts with Tekmira’s partners. While Tekmira considers these assumptions to be reasonable, these assumptions are inherently subject to significant business, economic, competitive, market and social uncertainties and contingencies.

Additionally, there are known and unknown risk factors which could cause Tekmira’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements contained herein. Known risk factors include, among others: the agreement with Monsanto may not result in the use of Tekmira’s technology in agricultural applications, or result in the payment (both quantum and timing) from Monsanto as anticipated, or at all; Tekmira’s technology many have no economically beneficial application in the field of agriculture; Monsanto may never exercise its option to receive a worldwide, exclusive right to use Tekmira’s proprietary LNP platform technology in the field of agriculture; Tekmira’s products may not prove to be effective or as potent as currently believed.

A more complete discussion of the risks and uncertainties facing Tekmira appears in Tekmira’s Annual Report on Form 20-F for the year ended December 31, 2012, which is available at xxx.xxxxx.xxx or at xxx.xxx.xxx/xxxxx. All forward-looking statements herein are qualified in their entirety by this cautionary statement, and Tekmira disclaims any obligation to revise or update any such forward-looking statements or to publicly announce the result of any revisions to any of the forward-looking statements contained herein to reflect future results, events or developments, except as required by law.
