VOTING AGREEMENT

This VOTING AGREEMENT (this “Agreement”) is made and entered into as of May 27, 2008, by and between Sonus Pharmaceuticals, Inc., a Delaware corporation (“Sonus”), and the signatory hereto (the “Securityholder”). Capitalized terms used and not defined herein have the same meaning as in the Arrangement Agreement, dated as of the date hereof (as such agreement may hereafter be amended or modified from time to time, the “Arrangement Agreement”), by and between Sonus and OncoGenex Technologies Inc., a corporation existing under the federal laws of Canada (“OncoGenex”).

WHEREAS, Sonus and OncoGenex will effect an arrangement under Section 192 of the CBCA, subject to the terms and conditions set forth in the Arrangement Agreement and Plan of Arrangement; and

WHEREAS, as a condition to entering into the Arrangement Agreement, Sonus has required that the Securityholder, solely in the Securityholder’s capacity as a holder of OncoGenex securities, enter into, and the Securityholder has agreed to enter into, this Agreement.

NOW, THEREFORE, in consideration of the premises, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereby agree as follows:

1. Representations and Warranties of the Securityholder. The Securityholder hereby represents and warrants to Sonus as follows:

(a) Authority; Binding Obligation. The Securityholder has all necessary power and authority to enter into this Agreement and perform all of the Securityholder’s obligations hereunder. This Agreement has been duly and validly executed and delivered by the Securityholder (and the Securityholder’s spouse, if the Securities (as defined below) constitute community property under applicable law) and constitutes a valid and legally binding obligation of the Securityholder and such spouse, enforceable against the Securityholder and such spouse, as the case may be, in accordance with its terms.

(b) Ownership of Securities. The Securityholder is the beneficial owner or record holder of the number of securities of OncoGenex listed on Schedule A attached hereto (the “Existing Securities” and, together with any securities of OncoGenex the record or beneficial ownership of which is acquired by the Securityholder after the date hereof, the “Securities”). The Existing Securities listed on Schedule A constitute all of the OncoGenex securities of record or beneficially owned by the Securityholder as of the date hereof. With respect to the Securities, the Securityholder has sole voting power and sole power to issue instructions with respect to or otherwise engage in the actions set forth in Section 2 hereof, and sole power of disposition, with no restrictions on the voting rights, rights of disposition or otherwise, subject to applicable laws and the terms of this Agreement.

(c) No Conflicts. Neither the execution, delivery and performance of this Agreement nor the consummation of the transactions contemplated hereby will conflict with or constitute a violation of or a default under (with or without notice, lapse of time, or both) any contract, agreement, voting agreement, shareholders’ agreement, trust agreement, voting trust, proxy, power of attorney, pooling arrangement, note, mortgage, indenture, instrument, arrangement or other obligation or restriction of any kind to which the Securityholder is a party or which the Securityholder or the Securityholder’s Securities are subject to or bound, other than the Shareholders’ Agreement, the applicable provisions of which have been waived by the Securityholder.

(d) Reliance. The Securityholder understands and acknowledges that Sonus is entering into the Arrangement Agreement in reliance upon the Securityholder’s execution and delivery of this Agreement.

2. Voting Agreement and Agreement Not to Transfer.

(a) The Securityholder hereby agrees to vote or cause to be voted all of the Securityholder’s Securities (i) in favor of the approval of the Arrangement Resolution and the Arrangement; (ii) against any action or agreement that would result in a breach in any material respect of any covenant, representation or warranty or any other obligation or agreement of OncoGenex under the Arrangement Agreement; and (iii) except with the prior written consent of Sonus, against the following actions (other than the Arrangement): (A) any extraordinary corporate transactions, such as an amalgamation, consolidation or other business combination involving OncoGenex; (B) any sale, lease, transfer or disposition of a material amount of the assets of OncoGenex; (C) any change in the board of directors of OncoGenex; (D) any material change in the present capitalization of OncoGenex; (E) any amendment of OncoGenex’s articles of incorporation or bylaws; (F) any other change in the corporate structure, business, assets or ownership of OncoGenex; or (G) any other action which is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or adversely affect the contemplated economic benefits to Sonus or OncoGenex of the Arrangement and the transactions contemplated by the Arrangement Agreement. The Securityholder shall not enter into any agreement, arrangement or understanding with any Person prior to the Termination Date (as defined in Section 7 below) to vote or give instructions, whether before or after the Termination Date, in any manner inconsistent with clauses (i), (ii) or (iii) of the preceding sentence.

(b) Upon the failure of the Securityholder to vote any Securities in accordance with the terms of this Agreement, the Securityholder hereby grants to the Chief Executive Officer and Chief Financial Officer of Sonus, and each of them individually, a proxy coupled with an interest in all Securities owned by the Securityholder, which proxy shall be irrevocable and survive until the Termination Date, to vote all such Securities in the manner provided in this Agreement. If between the execution hereof and the Termination Date, the Securityholder should die or become incapacitated, or if any trust or estate holding the Securityholder’s Securities should be terminated, or if any corporation or partnership holding the Securities should be dissolved or liquidated, or if any other such similar event or events shall occur before the Termination Date, any actions taken by

Sonus under this Agreement shall be as valid as if such death, incapacity, termination, dissolution, liquidation or other similar event or events had not occurred, regardless of whether or not Sonus has received notice of such death, incapacity, termination, dissolution, liquidation or other event.

(c) The Securityholder hereby agrees not to (i) sell, transfer, convey, assign or otherwise dispose of any of his, her or its Securities without the prior written consent of Sonus, other than Securities sold or surrendered or deemed sold or surrendered to pay the exercise price of any OncoGenex Options or to satisfy OncoGenex’s withholding obligations with respect to any Taxes resulting from such exercise or resulting from the vesting of restricted stock or restricted performance stock, or (ii) pledge, mortgage or otherwise encumber such Securities. Notwithstanding the foregoing, the Securityholder may complete any Permitted Transfer (as defined in Schedule B) without the prior written consent of Sonus. Any permitted transferee of the Securityholder’s Securities must become a party to this Agreement and any purported transfer of the Securityholder’s Securities to a Person that does not become a party hereto shall be null and void ab initio.

3. Cooperation. The Securityholder agrees that he or she will not (directly or indirectly) (i) encourage, initiate, solicit or take any other action designed to facilitate any Acquisition Proposal involving OncoGenex from any Person or (ii) exercise any dissent right that the Securityholder may have in connection with the Arrangement. Further, the Securityholder hereby agrees to execute and deliver, or cause to be executed or delivered, such additional proxies, consents, waivers and other instruments, and undertake any and all further action, necessary or desirable, in the reasonable opinion of Sonus, to carry out the purpose and intent of this Agreement and to consummate the Arrangement under the terms of the Arrangement Agreement.

4. Disclosure. The Securityholder hereby agrees to permit Sonus to publish and disclose in the Proxy Statement (including all documents and schedules filed with the SEC), and in any press release or other disclosure document which Sonus reasonably determines to be necessary or desirable to comply with applicable laws or the rules and regulations of Nasdaq or such other regulatory authority having jurisdiction in connection with the Arrangement and any transactions related thereto, Securityholder’s identity and ownership of OncoGenex Securities and the nature of Securityholder’s commitments, arrangements and understandings under this Agreement, provided that any public announcement or disclosure is made in accordance with the terms of the Arrangement Agreement.

5. Confidentiality. The Securityholder shall keep the existence and contents of this Agreement confidential and shall not disclose its existence or contents to any other person except as is necessary in order to enable the Securityholder to comply with its obligations hereunder or as may be required by Law. The Securityholder shall not, so long as Sonus has not announced the Arrangement to the public generally, disclose information about the Arrangement or this Agreement to any other person, unless such disclosure is necessary in the Securityholder’s course of business and the person receiving the information acknowledges that he or she is also prohibited from disclosing such information to others.

6. Securityholder Capacity. The Securityholder is entering this Agreement in his, her or its capacity as the record or beneficial owner of the Securities, and not in his, her or its capacity as a director or officer of OncoGenex.

7. Termination. The obligations of the Securityholder hereunder shall terminate:

(a) if the Arrangement is consummated, upon the consummation of the Arrangement;

(b) if the Arrangement is not consummated, upon the termination of the Arrangement Agreement in accordance with its terms;

(c) upon any material amendment to the Arrangement Agreement or Plan of Arrangement being given effect that has not been approved by the OncoGenex Shareholders;

(d) on August 31, 2008 if not otherwise terminated prior to such date and provided that the Proxy Statement is not subject to a review by the SEC; or

(e) on September 30, 2008 if not otherwise terminated prior to such date and provided that the Proxy Statement is reviewed by the SEC.

The “Termination Date” for any particular provision hereunder shall be the date of termination of the Securityholder’s obligations under such provision.

8. Specific Performance. The Securityholder acknowledges that it would be impossible to determine the amount of damages that would result from any breach of any of its obligations under this Agreement and that the remedy at law for any breach, or threatened breach, would likely be inadequate and, accordingly, agrees that Sonus shall, in addition to any other rights or remedies which it may have at law or in equity, be entitled to seek such equitable and injunctive relief as may be available from any court of competent jurisdiction to restrain the Securityholder from violating any of its obligations under this Agreement. In connection with any action or proceeding for such equitable or injunctive relief, the Securityholder hereby waives any claim or defense that a remedy at Law alone is adequate and agrees, to the maximum extent permitted by Law, to have the obligations of the Securityholder under this Agreement specifically enforced against him or her, without the necessity of posting bond or other security, and consents to the entry of equitable or injunctive relief against the Securityholder enjoining or restraining any breach or threatened breach of this Agreement.

9. Non-Resident Tax Matters. The Securityholder acknowledges and agrees as follows:

(a) Withholding Rights. Each of Sonus and the Depositary (as defined in the Plan of Arrangement) shall be entitled to withhold from any Sonus Common Shares or other consideration otherwise issuable or payable pursuant to the Plan of Arrangement to any holder of OncoGenex Shares and OncoGenex Debentures who is not a Canadian Resident (a “Non-Resident Holder”), such amounts as Sonus or the Depositary, respectively, are required to deduct and withhold with respect to such issuance or payment, as the case may be, under Sections 116 and 212 of the Income Tax Act, R.S.C. 1985, c.1 (5th Supp.), as amended (the “ITA”). Since the consideration paid to the Non-Resident Holder of OncoGenex Shares and OncoGenex Debentures under the Arrangement Agreement is in the form of Sonus Common Shares and not cash, and the liquidation value

of those shares is unknown, Sonus or the Depositary will initially holdback all Sonus Common Shares otherwise issuable to a Non-Resident Holder. Any amount actually paid to the Canada Revenue Agency (the “CRA”) by Sonus or by the Depositary when demanded by the CRA under the ITA on behalf of any Non-Resident Holder of OncoGenex Shares and OncoGenex Debentures will immediately become due and payable to Sonus by the Non-Resident Holder and shall bear interest at 15% per annum, compounded monthly. The Sonus Common Shares (including Deposited Securities) withheld according to this Section 9(a) will not be released to a Non-Resident Holder until the amounts owing to Sonus are paid in full or waived by Sonus or such conditions described in Section 9(b) are met. If there is no tax ultimately owing by the Non-Resident Holder to the CRA, the interest on the amounts remitted to the CRA by Sonus or the Depositary will be waived by Sonus. If there is an amount owing to Sonus (as a result of Sonus making a payment to the CRA on behalf of a Non-Resident Holder), Sonus shall be authorized to deposit the withheld shares in a segregated brokerage account in trust for the benefit of the Non-Resident Holder and the Non-Resident Holder shall be deemed to have provided the trustee of that account with irrevocable instructions to sell, on terms satisfactory to Sonus, a sufficient number of the withheld Sonus Common Shares to satisfy the taxes paid by Sonus or the Depositary on behalf of the Non-Resident Holder and interest accrued and remit those proceeds to Sonus. If upon the sale of all such Sonus Common Shares and the remittance of all of the related proceeds to Sonus, any remaining liability by the Non-Resident Holder to Sonus remains, that remaining liability shall be waived by Sonus. Notwithstanding the above, any Non-Resident Holder who remits in cash the full amount of tax withholdings potentially owing prior to the receipt of a Clearance Certificate (as defined below) or actually owing after the receipt of a Clearance Certificate, either directly to the CRA or to Sonus, shall have all of their withheld Sonus Common Shares released, subject to Section 2.2(e) of the Plan of Arrangement.

(b) Clearance Certificates. If any Sonus Common Shares or other consideration is deducted or withheld from a Non-Resident Holder pursuant to Section 116 of the ITA as described in Section 9(a), Sonus or the Depositary, as the case may be, shall, subject to Section 9(a), remit such consideration to such Non-Resident Holder upon delivery by such Non-Resident Holder to Sonus or the Depositary, as the case may be, of a certificate of compliance (with a certificate limit not less than the fair market value of the aggregate consideration to be paid to such Non-Resident Holder for their OncoGenex Shares pursuant to the terms of the Arrangement) issued pursuant to section 116 of the ITA (a “Clearance Certificate”). If such Non-Resident Holder does not so deliver a Clearance Certificate and withholding payment is demanded by the CRA, Sonus will remit sufficient funds to the CRA to comply with this remittance requirement; provided that, if Sonus or the Depositary, as the case may be, is provided with a letter from the CRA advising that none of the amounts deducted or withheld in respect of such Non-Resident Holder are required to be remitted, Sonus or the Depositary, as the case may be, will continue to hold such amounts in accordance with that letter until a Clearance Certificate is provided or until the CRA requires the amounts to be remitted, whichever shall first occur. Subject to Section 9(a), to the extent that amounts are so deducted or Sonus Common Shares withheld, the corresponding amounts will be immediately due and payable to Sonus, provided that such amounts, are actually remitted upon demand to the CRA in accordance with this section.

(c) Covenant to Apply for Clearance Certificate. The Securityholder hereby covenants and agrees that it will apply to CRA for a Clearance Certificate as soon as practicable after the Arrangement becomes effective to satisfy delivery of such certificate to Sonus as such delivery is contemplated in section 9(b) herein.

10. Miscellaneous.

(a) Definitional Matters.

(i) For purposes of this Agreement, “beneficial ownership” shall be determined in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, as amended.

(f) Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity and unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

(g) Governing Law. This Agreement shall be deemed to be made in and in all respects shall be interpreted, construed and governed by and in accordance with the laws of British Columbia, without regard to the conflict of law principles thereof.

(h) Jurisdiction and Venue. Any legal action or proceeding with respect to this Agreement shall be brought solely in a court of competent jurisdiction in the Province of British Columbia and, by execution and delivery of this Agreement, each of the Securityholder and Sonus hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of and venue in the aforesaid courts, notwithstanding any objections it may otherwise have. Each of the Securityholder and Sonus irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the delivery of notice as provided in Section 10(l) below, such service to become effective thirty (30) days after such delivery.

(i) Waiver of Trial by Jury. Each party acknowledges and agrees that any controversy which may arise under this Agreement is likely to involve complicated and difficult issues, and therefore each such party hereby irrevocably and unconditionally waives any right such party may have to a trial by jury in respect of any litigation directly or indirectly arising out of or relating to this Agreement, or the transactions contemplated by this Agreement. Each party certifies and acknowledges that (i) no representative, agent or attorney of the other party has represented, expressly or otherwise, that such party would not, in the event of litigation, seek to enforce the foregoing waiver, (ii) each party understands and has considered the implications of this waiver, (iii) each party makes this waiver voluntarily and (iv) each party has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 10(i).

(j) Attorney’s Fees.

All such judgments and awards shall contain a specific provision for the recovery of all such subsequently incurred costs, expenses, fees and disbursements of counsel.

(k) Counterparts. This Agreement may be executed in two or more counterparts, and by the different parties hereto in separate counterparts, each of which executed counterparts and any photocopies and facsimile copies thereof, shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.
