(b) Future Payments.

(i) Parent, or an entity designated by Parent, shall make a one-time payment in Parent Common Stock, subject to compliance with applicable regulatory requirements, to the Company Stockholders, in an amount equal to the First Future Amount within 10 Business Days after Parent, its Affiliates or Sublicensees Initiate a Phase III Clinical Trial;

The right of any Company Stockholder to receive any Future Amount does not give such Company Stockholder dividend rights, voting rights, liquidation rights, preemptive rights or other rights of holders of capital stock of the Company. The Parent Common Stock in the Escrow Fund shall be legally outstanding under applicable state law and appear as issued and outstanding on Parent's Financial Statements, all cash dividends paid on said Parent Common Stock shall be currently distributed to the Company Stockholders, and the Company Stockholders shall be entitled to exercise all voting rights with respect to said Parent Common Stock.

(b) From and after the Effective Time and subject to compliance with applicable regulatory requirements, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificate(s) are presented to the Surviving Corporation, as the case may be, for any reason, they shall be cancelled and converted into the right to receive the Merger Consideration in accordance with this Section 2.8.

(c) Prior to the Effective Time and subject to compliance with applicable regulatory requirements, Parent, Company, or Parent's designee, shall deliver to each holder of Common Stock that has not previously received the same (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass only upon delivery of the Certificates to Parent (the "Letter of Transmittal") and (ii) instructions for effecting the surrender of such Certificates in exchange for the consideration such holder of Common Stock has the right to receive in accordance with this Article II.

[+] DESIGNATES PORTIONS OF THIS DOCUMENT THAT HAVE BEEN OMITTED FOR CONFIDENTIALITY PURPOSES

of (A) the number of outstanding shares of Company Common Stock previously represented by such Certificate(s), multiplied by (B) the applicable Future Per Share Amount. The amounts paid by Parent, or its designee, in exchange for Certificates shall be deemed to be full payment and satisfaction of all rights pertaining to such shares of Company Common Stock.

(e) If any Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming a certificate to be lost, stolen or destroyed, the Parent, or its designee, will issue in exchange for this lost, stolen or destroyed certificate the Merger Consideration deliverable in respect thereof except that the Person to whom this Merger Consideration is paid shall, as a condition precedent to the payment thereof, indemnify the Surviving Corporation in a manner reasonably satisfactory to it against any claim that may be made against the Surviving Corporation with respect to the certificate alleged to have been lost, stolen or destroyed.

(f) If payment is to be made to a Person other than the registered holder of the Certificate(s) surrendered, it shall be a condition of payment that the surrendered Certificate must be properly endorsed or otherwise in proper form for transfer and that the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a Person other than the registered holder of the Certificate(s) surrendered or establish to the reasonable satisfaction of the Surviving Corporation or the Parent that this Tax has been paid or is not applicable.

Any amounts required to be withheld shall be satisfied first from the cash consideration payable to such person and then, if such cash consideration is not sufficient, from the stock consideration payable to such person. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

2.11 Capital Stock of Merger Sub. At the Effective Time, by virtue of the First Merger and without any action on the part of any of the parties hereto, each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and non-assessable share of common stock, par value $0.001 per share, of the First-Step Corporation.

2.12 No Fractional Shares. No fraction of a share of Parent Common Stock will be issued by virtue of the Merger, but in lieu thereof each Company Stockholder who would otherwise be entitled to a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that would otherwise be received by such Company Stockholder in respect of all shares of Company Common Stock held by such Company Stockholder) shall receive from Parent an amount of cash (rounded to the nearest whole cent), equal to the product of such fraction multiplied by the closing sale price of one share of Parent Common Stock as reported on the Nasdaq Global Market on the Closing Date.

2.13 Payment in Stock.

(a) The shares of Parent Common Stock issued as part of the Initial Stock Consideration or as part of the Third Future Payment, if any, will not be registered under the Securities Act of 1933, as amended (the "Securities Act").

Parent may instruct its transfer agent to stop the transfer of any shares of Parent Common Stock issued as part of the Initial Stock Consideration or as part of the Third Future Payment, if any, to provide for compliance with the provisions of this paragraph.

(b) Each certificate representing shares of Parent Common Stock (unless and until such shares are registered pursuant to this Agreement) shall bear legends substantially in the form set forth below:

"THE SHARES SUBJECT TO THIS CERTIFICATE WERE ISSUED PURSUANT TO THAT CERTAIN AGREEMENT AND PLAN OF REORGANIZATION BY AND AMONG PROLX PHARMACEUTICALS CORPORATION ("PROLX"), BIOMIRA INC., AND CERTAIN OTHER NAMED STOCKHOLDERS OF PROLX (THE "MERGER AGREEMENT") AND ARE SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN THE MERGER AGREEMENT AND ANCILLARY AGREEMENTS RELATED THERETO, INCLUDING THE CERTIFICATE OF STOCKHOLDER. THE SALE AND ISSUANCE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES LAW OF ANY STATE OR OTHER JURISDICTION. THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE DISTRIBUTION THEREOF. THESE SECURITIES MAY NOT BE OFFERED, SOLD, PLEDGED, OR TRANSFERRED UNLESS (1) A REGISTRATION STATEMENT UNDER THE ACT IS IN EFFECT AS TO THESE SECURITIES AND SUCH OFFER, SALE, PLEDGE, OR TRANSFER IS IN COMPLIANCE WITH APPLICABLE SECURITIES LAW OF ANY STATE OR OTHER JURISDICTION, (2) THE SALE IS MADE IN ACCORDANCE WITH RULE 144 PROMULGATED UNDER THE ACT, OR (3) THERE IS AN OPINION REASONABLY SATISFACTORY TO THE CORPORATION FROM COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION, THAT AN EXEMPTION FROM THE ACT IS AVAILABLE AND THAT SUCH OFFER, SALE, PLEDGE OR TRANSFER IS IN COMPLIANCE WITH THE PROVISIONS OF THE MERGER AGREEMENT AND THE ANCILLARY AGREEMENTS RELATED THERETO, INCLUDING THE CERTIFICATE OF STOCKHOLDER."

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE ("TSX"); HOWEVER, THE SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT "GOOD DELIVERY" IN SETTLEMENT OF TRANSACTIONS ON TSX."

Notwithstanding anything in this Agreement to the contrary, Company Common Stock outstanding immediately prior to the Effective Time and held by a stockholder who has not voted in favor of the Merger or consented thereto in writing and who has delivered a written demand for appraisal of such shares in accordance with Section 262 of the DGCL, if such Section 262 provides for appraisal rights for such Company Common Stock in the Merger ("Dissenting Shares"), shall not be converted into the right to receive the Merger Consideration, as provided in Section 2.8 hereof, unless and until such holder fails to perfect or effectively withdraws or otherwise loses his right to appraisal and payment under the DGCL. If, after the Effective Time, any such stockholder fails to perfect or effectively withdraws or loses his right to appraisal, such Dissenting Shares shall thereupon be treated as if they had been converted as of the Effective Time into the right to receive the Company Common Stock Consideration to which such holder is entitled, without interest or dividends thereon. The Company shall give Parent prompt notice of any demands received by Company for appraisal of Company Common Stock.

2.15 Taking of Necessary Action; Further Action. If at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the First-Step Corporation and/or the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, Parent and Merger Sub are fully authorized in the name of their respective corporations or otherwise to take, and will take, all such lawful and necessary action.

2.18 Registration Statement.

(a) Registration. Parent agrees that it shall use its commercially reasonable efforts to cause to be filed not later than thirty (30) business days following the date on which the First and Second Future Payments are due, a registration statement on Form F-3 (the "Registration Statement") under the Securities Act for an offering to be made on a delayed or continuous basis pursuant to Rule 415 thereunder or any similar rule that may be adopted by the SEC and permitting sales in ordinary course brokerage or dealer transactions not involving any underwritten public offering, covering all of the shares of Parent Common Stock issued to the Company Stockholders pursuant to Section 2.7(b)(i) and Section 2.7(b)(ii) of this Agreement, and any other securities issued by Parent as a dividend or other distribution with respect to, or in exchange for or in replacement of, such shares ("Registrable Shares"). Parent shall use commercially reasonable efforts thereafter to cause the Registration Statement to be declared effective by the SEC as promptly as practicable. Parent may postpone the filing or the effectiveness of the Registration Statement for a period of up to sixty (60) days if Parent determines in good faith that the filing or effectiveness of the Registration Statement would require the disclosure of information that could be materially detrimental to Parent or its stockholders; provided, however, that Parent shall not be required to disclose such information (or the nature thereof) to the holders of Registrable Shares ("Holders") or the Stockholder Representative. Subject to Section 2.18(b), Parent shall use commercially reasonable efforts to keep the Registration Statement continuously effective until the earlier to occur of (A) the one-year anniversary of the date on which the Registration Statement is declared effective by the SEC (the "Termination Date") and (B) the first date on which no Registrable Shares originally covered by the Registration Statement shall constitute Registrable Shares.

(b) Stop Order; Amendment of Prospectus.

(i) Parent will notify the Holders promptly of (i) the issuance of any stop order suspending the effectiveness of the Registration Statement or (ii) the receipt by Parent of any notification with respect to the suspension of the qualification of the Registrable Shares for sale in any jurisdiction. Immediately upon receipt of any such notice, the Holders shall cease to offer and sell any Registrable Shares pursuant to the Registration Statement in the jurisdiction to which such stop order or suspension relates. Parent shall use commercially reasonable efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if any such stop order is issued or any such qualification is suspended, to obtain as soon as possible the withdrawal or revocation thereof, and will notify the Holders at the earliest practicable date of the date on which the Holders may offer and sell Registrable Shares pursuant to the Registration Statement.

(ii) Parent will notify the Holders promptly if Parent is in possession of material non-public information that an executive officer of Parent determines in good faith should not be disclosed because it would be materially detrimental to Parent or its stockholders but would otherwise be

[+] DESIGNATES PORTIONS OF THIS DOCUMENT THAT HAVE BEEN OMITTED FOR CONFIDENTIALITY PURPOSES

required to be set forth in the prospectus used in connection with the Registration Statement (a "Prospectus"); provided, however, that Parent shall not be required to disclose such event or facts, or the nature thereof, to the Holders or the Stockholder Representative. Immediately upon receipt of such notice, and provided that an equivalent trading suspension has been imposed on, and is then applicable to, all of Parent's executive officers, directors and other holders of Parent Common Stock which are registered for resale under the Securities Act, the Holders shall cease to offer or sell any Registrable Shares pursuant to the Prospectus, cease to deliver or use such Prospectus and, if so requested by Parent, return to Parent, at Parent's expense, all copies (other than permanent file copies) of such Prospectus. Promptly after Parent determines that the information may be included in an amendment or supplement to any Prospectus, Parent will use commercially reasonable efforts to amend or supplement the Prospectus as promptly as practicable in order to set forth or reflect such event or state of facts. Notwithstanding the foregoing, in the event that an executive officer of Parent determines in good faith that the disclosure of such information in an amendment or supplement would be materially detrimental to Parent or its stockholders, Parent shall be permitted to delay the filing of such an amendment or supplement to such Prospectus for a period of time to extend no longer than sixty (60) days. Parent will promptly furnish copies of such amendment or supplement to such Prospectus to the Holders and notify Holders when trading may once again commence.

(c) Information Concerning the Holders. The obligations of Parent to take the actions contemplated by Section 2.18(a) with respect to an offering of Registrable Shares of each Holder shall be subject to the condition that such Holder shall (i) conform to all applicable requirements of the Securities Act and the Exchange Act with respect to the offering and sale of securities and (ii) advise each underwriter, broker or dealer through which any of such Registrable Shares are offered that such Registrable Shares are part of a distribution that is subject to the prospectus delivery requirements of the Securities Act. Each Holder whose Registrable Securities will be covered by the Registration Statement shall furnish to Parent in writing such information and furnish such documents as may be reasonably required by Parent in the preparation of (A) a Prospectus (or any amendment or supplement thereto) with respect to any offering of Registrable Shares and (B) any qualification of such Registrable Shares under state securities or "blue sky" laws, and shall promptly notify Parent of the occurrence, from the date on which such information or documents are furnished to the date of the closing for the sale of such Registrable Shares, of any event relating to such Holder that is required under the Securities Act to be set forth in such Prospectus (or any amendment or supplement thereto).

(g) Resolution of Conflicts; Arbitration.

(i) In case the Stockholder Representative shall object in writing to any claim or claims made in any Officer's Certificate to recover Losses from the Available Escrow Fund within 30 days after delivery of such Officer's Certificate, the Stockholder Representative and Parent shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholder Representative and Parent should so agree, a memorandum setting forth any agreement reached by the parties with respect to such claim shall be prepared and signed by both parties. Parent and the Stockholder Representative shall each be entitled to rely on any such memorandum and take any actions as may otherwise be contemplated in such memorandum.

(ii) If no such agreement can be reached after good faith negotiation and prior to 60 days after delivery of an Officer's Certificate, either Parent or the Stockholder Representative may demand arbitration of the matter unless the amount of the Loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration, and in either such event the matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to Parent and the Stockholder Representative. In the event that, within 30 days after submission of any dispute to arbitration, Parent and the Stockholder Representative cannot mutually agree on one arbitrator, then, within 15 days after the end of such 30 day period, Parent and the Stockholder Representative shall each select one arbitrator. The two arbitrators so selected shall select a third arbitrator. If the Stockholder Representative fails to select an arbitrator during this 15 day period, then the parties agree that the arbitration will be conducted by one arbitrator selected by Parent. If Parent fails to select an arbitrator during this 15-day period, then the parties agree that the arbitration will be conducted by one arbitrator selected by Stockholder Representative.

(iii) Any such arbitration shall be held in San Francisco, California, under the rules then in effect of the American Arbitration Association. The arbitrator(s) shall determine how all expenses relating to the arbitration shall be paid, including, the respective expenses of each party, the fees of each arbitrator and the administrative fee of the American Arbitration Association. The arbitrator or arbitrators, as the case may be, shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrator or majority of the three arbitrators, as the case may be, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrator, or a majority of the three arbitrators, as the case may be, shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys' fees and costs, to the same extent as a competent court of law or equity, should the arbitrators or a majority of the three arbitrators, as the case may be, determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. The decision of the arbitrator or a majority of the three arbitrators, as the case may be, as to the validity and amount of any claim in such Officer's Certificate shall be final, binding, and conclusive upon the parties to this Agreement. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s), and Parent shall be entitled to rely on, and make permanent retentions from the Available Escrow Fund in accordance with, the terms of such award, judgment, decree or order as applicable. Within 30 days of a decision of the arbitrator(s) requiring payment by one party to another, such party shall make the payment to such other party.

[+] DESIGNATES PORTIONS OF THIS DOCUMENT THAT HAVE BEEN OMITTED FOR CONFIDENTIALITY PURPOSES

(iv) Judgment upon any award rendered by the arbitrator(s) may be entered in any court having jurisdiction, subject to Section 7.8. The forgoing arbitration provision shall apply to any dispute between the Company Stockholders, on the one hand, and any Indemnified Party, on the other hand, under this Article VI hereof, whether relating to claims upon the Escrow Fund or to the other indemnification obligations set forth in this Article VI.

(h) Third Party Claims.

(i) In the event Parent becomes aware of a third party claim which Parent reasonably believes may result in a demand against the Available Escrow Fund or for other indemnification pursuant to this Article VI, Parent shall notify the Stockholder Representative of such claim.

(ii) The Stockholder Representative shall be entitled on behalf of the Company Indemnifying Parties, at its expense, to assume control of the defense of the Parent Indemnified Party against the third party claim, with counsel reasonably satisfactory to such Parent Indemnified Party. Parent shall cooperate fully with Stockholder Representative in conducting the defense of such claim, and shall be entitled, at its own expense, to be represented by legal counsel of its own choosing. The expenses of any such additional counsel shall not be deemed Losses hereunder unless Parent reasonably determines, based on the advice of legal counsel, that the Company Indemnifying Parties and the Parent Indemnified Parties cannot be adequately represented by a single legal counsel. The Stockholder Representative shall not without the prior written consent of the Parent Indemnified Parties consent to the entry of any judgment or enter into any settlement that (i) does not provide for the payment of money as the sole and exclusive remedy and (ii) does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Parent Indemnified Party of a release from all liability in respect of such claim.

(iii) If the Stockholder Representative shall decline to conduct such defense, then Parent shall have the right to conduct such defense and settle such claim, but amounts incurred or accrued by the Parent Indemnified Parties in defense of such third party claim, or paid in settlement thereof, shall not be deemed Losses hereunder unless the Stockholder Representative shall have provided his advance written consent to the terms of such settlement. In the event that the Stockholder Representative has consented to any such settlement, the Company Indemnifying Parties shall have no power or authority to object under any provision of this Article VI to the amount of any claim by Parent against the Escrow Fund for the amount of such settlement.

(a) Each of the Indemnifying Parties hereby appoint ▇▇▇▇▇ ▇▇▇▇▇ as its agent and attorney in fact as the Stockholder Representative for and on their behalf to give and receive notices and communications, to authorize payment to the Parent from the Available Escrow Fund in satisfaction of claims by Parent, to object to such payments, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all other actions that are either (i) necessary or appropriate in the judgment of either of the Stockholder Representative for the accomplishment of the foregoing or (ii) specifically mandated by the terms of this Agreement. Such agency may be changed by the Indemnifying Parties from time to time upon not less than 30 days prior written notice to Parent; provided, however, that the Stockholder Representative may not be removed unless holders of a two thirds interest of the Escrow Fund agree to such removal and to the identity of the substituted agent. A vacancy in the position of Stockholder Representative may be filled by the holders of a majority in interest of the Escrow Fund. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall not receive any compensation for its services. Notices or communications to or from the Stockholder Representative shall constitute notice to or from the Indemnifying Parties.

(b) The Stockholder Representative shall not be liable for any act done or omitted hereunder as Stockholder Representative while acting in good faith and in the exercise of reasonable judgment. Any loss, liability or expense incurred without negligence or bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of the Stockholder Representative's duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Stockholder Representative, shall be referred to herein as "Stockholder Representative Expenses". The Indemnifying Parties on whose behalf the Aggregate Escrow Amount was contributed to the Escrow Fund agree that the Stockholder Representative shall have the right to be reimbursed solely from the Escrow Fund for the Stockholder Representative Expenses. Following the termination of the Escrow Period and the resolution of all pending claims made by the Parent Indemnified Parties for Losses, the Stockholder Representative shall have the right to recover the Stockholder Representative Expenses from any remaining portion of the Available Escrow Fund prior to any distribution to the Indemnifying Parties, and prior to any such distribution, the Stockholder Representative shall deliver to Parent a certificate setting forth the Stockholder Representative Expenses to the Stockholder Representative. For the purposes of determining how many shares of Parent Common Stock the Stockholder Representative shall be entitled to recover for any Stockholder Representative Expenses hereunder, each share of Parent Common Stock shall have a value equal

to the average closing sale price of one share of Parent Common Stock as reported on the Nasdaq Global Market for the ten consecutive trading days ending three trading days immediately preceding the date of payment for such Stockholder Representative Expenses. Notwithstanding the foregoing, the Stockholder Representative's right to recover Stockholder Representative Expenses shall not prejudice Parent's right to recover the full amount of indemnifiable Losses that Parent is entitled to recover from the Escrow Fund.

(c) A decision, act, consent or instruction of the Stockholder Representative, including but not limited to an amendment, extension or waiver of this Agreement pursuant to Section 8.1 hereof, shall constitute a decision of the Indemnifying Parties and shall be final, binding and conclusive upon the Indemnifying Parties; and Parent may rely upon any such decision, act, consent or instruction of the Stockholder Representative as being the decision, act, consent or instruction of the Indemnifying Parties. Parent is hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholder Representative.

6.8 Tax Treatment. Any payments under this Article VI shall be treated as an adjustment to the Merger Consideration for all Tax purposes.

6.9 Net of Insurance Proceeds and Tax Benefits. In calculating the amount of any Loss, such Loss shall be reduced by any net Tax benefit actually recognized or to be recognized by the Indemnified Parties (or any Affiliates thereof) relating to such Loss and any insurance recovery with respect to such Loss.
