MATERIAL BREACH OF THIS AGREEMENT

Section 8.1Material Breach. Failure by a Party to comply with any of its material obligations contained herein will entitle the Party not in default to give to the defaulting Party notice specifying the nature of the material breach, requiring the defaulting Party to make good or otherwise cure such default, and stating its intention to trigger the provisions of Section 12.5 if such default is not cured. If such default is not cured within 90 days after the receipt of such notice (or, if such default cannot be cured within such 90-day period, if the Party in default does not commence actions to cure such default within such period and thereafter diligently continue such actions), the Party not in default will be entitled, without prejudice to any of its other rights conferred on it by this Agreement, to trigger the provisions of Section 12.5.; provided, however, that in the event of a good faith dispute with respect to the existence of a material breach, the 90-day cure period will be stayed until such time as the dispute is resolved pursuant to Section 12.5 hereof.

Within 90 days of receipt by Isis of a Discontinuance Notice, Isis may elect to unilaterally continue development of any antisense oligonucleotide generated under the Project Plan by notice in writing to OncoGenex (an “Election Notice”) that Isis is exercising its rights under this Section 9.2.

INDEMNIFICATION AND INSURANCE

Section 10.1Indemnification of Isis. OncoGenex will indemnify Isis, and its respective directors, officers, employees and agents, and defend and hold each of them harmless, from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) but only to the extent arising from or occuring as a result of any and all liability suits, investigations, claims or demands by a Third Party (collectively, “Losses”) arising from or occurring as a result of or in connection with (a) any material breach by OncoGenex of this Agreement, (b) the gross negligence or willful misconduct on the part of OncoGenex or its licensees or sublicensees in performing any activity contemplated by this Agreement, or, , (c) the manufacture, use, handling, storage, sale or other disposition of a Product that is sold by OncoGenex, its Affiliates, agents or sublicensees; in each case, except for those Losses for which Isis has an obligation to indemnify OncoGenex pursuant to Section 10.2, as to which Losses each Party will indemnify the other to the extent of their respective liability for the Losses, or except as may be provided under a supply agreement under Section 2.4.

Section 10.2Indemnification of OncoGenex. Isis will indemnify OncoGenex,  and its respective directors, officers, employees and agents, and defend and save each of them harmless, from and against any and all Losses arising from or occurring as a result of or in connection with (a) any material breach by Isis of this Agreement, or (b) the gross negligence or willful misconduct on the part of Isis or its licensees or sublicensees in performing any activity contemplated by this Agreement, or, (c) the manufacture, use, handling, storage, sale or other disposition of a Product that is sold by Isis, its Affiliates, agents or sublicensees; in each case, except for those Losses for which Isis has an obligation to indemnify OncoGenex pursuant to Section 10.1, as to which Losses each Party will indemnify the other to the extent of their respective liability for the Losses, or except as may be provided under a supply agreement under Section 2.4.

Section 10.3Indemnification Procedure.

10.3.1Notice of Claim. The indemnified Party will give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any claim upon which such indemnified Party intends to base a request for indemnification under Section 10.1 or Section 10.2, but in no event will the indemnifying Party be liable

15

for any losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such loss (to the extent that the nature and amount of such loss are known at such time). The indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any claim or losses. All indemnification claims in respect of a Party, its Affiliates or their respective directors, officers, employees and agents (collectively, the “Indemnitees” and each an “Indemnitee”) will be made solely by such Party to this Agreement (the “Indemnified Party”).

10.3.2Third Party Claims. The obligations of an indemnifying Party under this Article 10 with respect to losses arising from claims of any Third Party that are subject to indemnification as provided for in Section 10.1 or 10.2 (a “Third Party Claim”) will be governed by and be contingent upon the following additional terms and conditions:

(a)Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within 30 days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party will not be construed as an acknowledgment that the indemnifying Party is liable to indemnify any Indemnitee in respect of the Third Party Claim, nor will it constitute a waiver by the indemnifying Party of any defenses it may assert against any Indemnitee’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by any Indemnitee in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, the indemnifying Party will not be liable to the Indemnified Party or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless an Indemnitee from and against the Third Party Claim, the Indemnified Party will reimburse the indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) and any Losses incurred by the indemnifying Party in its defense of the Third Party Claim with respect to such Indemnitee.

(b)Right to Participate in Defense. Without limiting Section 10.3.2(a), any Indemnitee will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnitee’s own expense unless (i) the employment thereof has been specifically authorized by the indemnifying Party in writing, or (ii) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 10.3.2(a) (in which case the Indemnified Party will control the defense).

16

(c)Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnitee’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnitee in any manner, and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnitee hereunder, the indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 10.3.2(a), the indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld or delayed). The indemnifying Party will not be liable for any settlement or other disposition of a loss by an Indemnitee that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnitee will admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party.

(d)Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnitee to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

(e)Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any claim will be reimbursed on a calendar quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

Section 10.4Insurance. Each Party will have and maintain such types and amounts of liability insurance as is normal and customary in the industry generally for parties similarly situated, and will upon request provide the other Party with a certificate

17

of insurance. Each party will promptly notify the other Party of any material change in insurance coverage or lapse in coverage in that regard.

ARTICLE 12 -

MISCELLANEOUS

Section 12.1Force Majeure. Neither Party will be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), insurrections, riots, civil commotion, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority. The non-performing Party will notify the other Party of such force majeure within ten (10) days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance will be of no greater scope and no longer duration than is necessary and the non-performing Party will use Commercially Reasonable Efforts to remedy its inability to perform; provided, however, that in the event the suspension of performance continues for one-

19

hundred and eighty (180) days after the date of the occurrence, the Parties will meet to discuss in good faith how to proceed in order to accomplish the goals of the Collaboration outlined in this Agreement.

Section 12.2Assignment. Without the prior written consent of the other Party hereto, neither Party will sell, transfer, assign, delegate, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that either Party hereto may assign or transfer this Agreement or any of its rights or obligations hereunder without the consent of the other Party to any Third Party with which it has merged or consolidated, or to which it has transferred all or substantially all of its assets to which this Agreement relates if in any such event the Third Party assignee or surviving entity assumes in writing all of the assigning Party’s obligations under this Agreement. Any purported assignment or transfer in violation of this Section will be void ab initio and of no force or effect.

Section 12.3Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable by a court of competent jurisdiction, such adjudication shall not affect or impair, in whole or in part, the validity, enforceability, or legality of any remaining portions of this Agreement. All remaining portions shall remain in full force and effect as if the original Agreement had been executed without the invalidated, unenforceable or illegal part.

Section 12.4Governing Law. This Agreement will be governed by and construed in accordance with the laws of Delaware without reference to any rules of conflicts of laws.

Section 12.5Dispute Resolution.

12.5.1General. Any dispute, controversy or claim arising from or related to this Agreement or the breach thereof will first be referred to the attention of the Chief Executive Officers of each of the Parties by notice in writing in accordance with the terms of this Agreement. The Chief Executive Officers (or their respective designees) will meet as soon as reasonably possible thereafter, and use their good faith efforts to mutually agree upon the resolution of the dispute, controversy or claim. If any dispute, controversy or claim is not resolved by the Chief Executive Officers of the Parties (or their designees) within 30 days after such dispute is referred to them, then either Party will have the right to arbitrate such dispute in accordance with Section 12.5.2.

12.5.2Arbitration. If the Parties do not fully settle any dispute, controversy or claim pursuant to Section 12.5.1 and a Party wishes to pursue the matter further, each such dispute, controversy or claim will be finally resolved by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”), and judgment on the arbitration award may be entered in any court having jurisdiction thereof. The arbitration will be conducted by a panel of three persons experienced in the pharmaceutical or biotech business: within 30 days after initiation of arbitration, each Party will select one person to act as arbitrator and the two

20

Party-selected arbitrators will select a third arbitrator within 30 days of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator will be appointed by the AAA. No individual shall be appointed to arbitrate a dispute pursuant to this Agreement unless he or she agrees in writing to be bound by the provisions of this Section 12.5. The place of arbitration will be Seattle, Washington. Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved.

12.5.3Disputes Regarding Material Breach. If the Parties are in dispute as to whether one party is in material breach of this Agreement, then the arbitrators will first determine if material breach has in fact occurred, and if so, will grant the defaulting Party the cure period provided pursuant to Section 8.1. If the material breach is not cured within the time period provided pursuant to Section 8.1, the arbitration will continue and the arbitrators will, as part of the same arbitration, award damages to the non-defaulting Party.

12.5.4Costs and Expenses. Except as expressly provided herein, each Party will bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ and any administrative fees of arbitration. Notwithstanding the foregoing, if a Party has been found to be in material breach of this Agreement, the defaulting Party will be responsible for both Parties’ costs and expenses (including the costs of the arbitrators and any administrative fees of arbitration) and the reasonable attorneys’ fees of the non-defaulting Party.

12.5.5Procedure. Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event will an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable Delaware statute of limitations.

12.5.6Speedy Resolution. The Parties intend, and shall take all reasonable action as is necessary or desirable to ensure, that there be a speedy resolution to any dispute which becomes the subject of arbitration, and the arbitrators shall conduct the arbitration so as to resolve the dispute as expeditiously as possible.

12.5.7Awards. The arbitrators may award monetary damages and injunctive relief, but may not order the granting or termination of licenses or assign rights to a Product to either of the Parties. Monetary damages shall be in the form of off-set royalties or otherwise, to account for the damages to the non-defaulting Party from the breach, and to account for the defaulting Party’s contribution to the Product in view of the breach. All awards shall be in writing and shall state reasons. Executed copies of all awards shall be delivered by the arbitrators to the Parties as soon as is reasonably possible. All awards of the arbitrators shall be final and binding on the Parties, and there shall be no appeal of any such award whatsoever. The Parties undertake to satisfy any award without delay.
