DDi acknowledges and agrees that the Pre-Acquisition Reorganizations shall not (A) delay or prevent consummation of the Arrangement and the other Transactions contemplated herein (including by giving rise to litigation by third parties or the need for prior approval of the Coretec Shareholders unless any such matter may be approved at the Coretec Meeting), or (B) be considered in determining whether a representation or warranty of Coretec hereunder has been breached, it being acknowledged by DDi that these actions could require the consent of third parties under applicable contracts. DDi shall provide written notice to Coretec of any proposed Pre-Acquisition Reorganization at least ten days prior to the Effective Date. Upon receipt of such notice, DDi and Coretec shall work cooperatively and use commercially reasonable efforts to prepare prior to the Effective Time all documentation necessary and do such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganizations.

any Pre-Acquisition Reorganization shall not in the determination of Coretec, acting reasonably, unreasonably interfere in the material operations prior to the Effective Time of Coretec or any of its subsidiaries;

(iv)

unless the parties otherwise agree, any Pre-Acquisition Reorganization shall not require any filings with, notifications to or approvals of any Governmental Entity or third party (except those that may be required or are advisable and that are routine or readily obtainable);

(v)

any Pre-Acquisition Reorganization shall not require Coretec or any subsidiary to contravene any applicable Laws, their respective organizational documents or any contract or Canadian GAAP; and

(vi)

Coretec and its Subsidiaries shall not be obligated to take any action that could result in any Taxes being imposed on, or any adverse Tax or other consequences to, any securityholder of Coretec incrementally greater than the Taxes or other consequences to such party in connection with the consummation of the Arrangement in the absence of any Pre-Acquisition Reorganization.

The provisions of this Section 9(j) are intended for the benefit of, and shall be enforceable by,

each insured or indemnified person, his or her heirs and his or her legal representatives and, for such purpose, Coretec hereby confirms that it is acting as agent and trustee on their behalf.

15.

No Solicitation:

From the date hereof and continuing until the Termination Date or the Completion Deadline, Coretec agrees that neither it nor its Affiliates, advisors or representatives (including any person or entity, directly or indirectly, through one or more intermediaries, controlled by or under common control with Coretec) will, directly or indirectly, (i) solicit or otherwise facilitate (including by way of furnishing information), initiate, encourage, engage in or respond to any inquiries or proposals regarding an Acquisition Proposal, (ii) encourage or participate in any discussions or negotiations regarding any Acquisition Proposal, (iii) agree to, approve or recommend an Acquisition Proposal, (iv) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in any manner, the approval or Recommendation of the Coretec board of directors or any committee thereof of this Agreement; (v) approve or recommend, or remain neutral with respect to, or propose publicly to approve or recommend, or remain neutral with respect to, any Acquisition Proposal, or (vi) enter into any agreement related to an Acquisition Proposal; provided, however, that subject as hereinafter provided, nothing shall prevent Coretec from furnishing non public information to, or entering into a confidentiality agreement and/or participating in discussions or negotiations with, any person in response to a bona fide unsolicited written Acquisition Proposal that is submitted by such person after the date hereof which is not withdrawn if (A) the directors of Coretec conclude in good faith, based on information then available and after consultation with Coretec’s financial advisors (if any) that such Acquisition Proposal constitutes a Superior Proposal or could reasonably or could reasonably be expected to result in a Superior Proposal; and (B) prior to providing any non-public information to such person in connection with such Acquisition Proposal, the Coretec board of directors receives from such person an executed confidentiality agreement containing terms no less favourable to Coretec as the terms of the Confidentiality Agreement and Coretec sends a copy of any such confidentiality agreement to DDi as promptly as reasonably practical upon its execution and as promptly as reasonably practical provides DDi a list of, or in the case of information that was not previously made available to DDi, copies of, any information provided to such person.

Concurrent with the execution hereof Coretec shall, except where prohibited by any existing confidentiality agreement, advise DDi of any current Acquisition Proposal and Coretec shall as promptly as reasonably practical (and in any event within 24 hours) notify DDi, first orally and then in writing, of any Acquisition Proposal which any director, senior officer or agent thereof is or becomes aware of after the date hereof (including any Acquisition Proposal made after the date hereof from any person who previously made an Acquisition Proposal to Coretec and any Acquisition Proposal from a person who has made a current Acquisition Proposal, the disclosure of which to DDi hereunder is prohibited by any existing confidentiality agreement), any amendment to any such proposal or any request for non-public information relating to Coretec or the Coretec Subsidiaries. Such notice shall include a description of the material terms and conditions of any such Acquisition Proposal and the identity of the person making such proposal, inquiry, request or contact.

Coretec shall immediately after the execution hereof terminate all existing discussions or negotiations with any person (other than DDi) with respect to any current or potential Acquisition Proposal.

16.

Superior Proposals:

(a)

Coretec or the directors thereof may take any action that is prohibited by Sections 15(iii), (iv), (v) or (vi) in respect of any Acquisition Proposal only if:

(i)

such Acquisition Proposal constitutes, or would constitute, if consummated in accordance with its terms, a Superior Proposal;

(ii)

such Acquisition Proposal is in writing and DDi has been provided with a copy of the document containing such Superior Proposal;

(iii)

five Business Days have elapsed from the date on which DDi received written notice of the determination of Coretec or the directors thereof to accept, approve or recommend or to enter into an agreement in respect of such Superior Proposal;

(iv)

in the event that DDi has proposed to amend this Agreement during the five Business Day period referred to above, the Coretec board of directors (after receiving advice from its financial advisors (if any) and outside legal counsel) shall have determined in good faith that the Acquisition Proposal continues to constitute a Superior Proposal after taking into account such amendments;

(v)

Coretec’s board of directors, after consultation with outside legal counsel, determines in good faith that the failure to take such action would be inconsistent with its fiduciary duties under all applicable Laws; and

(vi)

Coretec terminates this Agreement pursuant to Section 18 hereof and Coretec concurrently makes the payment contemplated by, and in accordance with, Section 17 hereof.

(b)

Coretec acknowledges that each successive modification to any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of the requirement under Section 16(a)(iii) hereof and shall initiate a new three Business Day period.

(c)

If the Coretec Proxy Circular has been sent to Coretec Shareholders prior to the expiry of the five Business Day period set forth in Section 16(a)(iii) and, during such period, DDi requests in writing that the Coretec Meeting proceed, unless otherwise ordered by the Court, Coretec shall take all reasonable steps necessary to hold the Coretec Meeting and to cause the Arrangement Resolution to be voted on at the Coretec Meeting.

(d)

If Coretec has provided DDi with a notice under Section 16(a), the Acquisition Proposal has been publicly disclosed or announced, and the Acquisition Proposal is provided to DDi within 10 days of the scheduled Coretec Meeting, then, subject to applicable Laws, at DDi’s request, Coretec will postpone or adjourn the Coretec Meeting at the Coretec Meeting (but not beforehand without DDi’s consent) to a date acceptable to DDi, acting reasonably, which shall not be later than ten days after the scheduled date of the Coretec Meeting and shall, in the event that DDi and Coretec amend the terms of this Agreement as contemplated by Section 16(a)(iv), ensure that the details of such amended Agreement are communicated to the Coretec Shareholders prior to the resumption of the adjourned Coretec Meeting.

(d)

Nothing in this Agreement shall prevent the board of Coretec from responding in a manner that is consistent with and in accordance with the provisions of Section 15, through a directors’ circular or otherwise as required by applicable Laws to an Acquisition Proposal that it determines is not a Superior Proposal.

17.

Termination Fee:

If:

(i)

Coretec terminates this Agreement under Section 18(a)(i) hereof in the circumstances permitted by Section 16; or

(ii)

an Acquisition Proposal (a “Pending Coretec Acquisition Proposal”) shall have been publicly announced after the date hereof and such Pending Coretec Acquisition Proposal shall not have been publicly withdrawn prior to the Coretec Meeting, if any, and, thereafter the Coretec Required Vote shall not have been obtained (including if the Coretec Meeting is not held) and Coretec completes such Pending Coretec Acquisition Proposal within 12 months following the Completion Deadline,

(any such event being a “Triggering Event”), then Coretec shall pay DDi an amount in cash equal to US$1,000,000 in immediately available funds to an account designated by DDi. Such payment shall be made (a) in the case of a Triggering Event described in Section 17(i), concurrently with such termination (and shall be a condition to the effectiveness of such termination by Coretec) or (b) in the case of a Triggering Event described in Section 17(ii), concurrently with completion of the Pending Coretec Acquisition Proposal. The obligation to make any payment required by this Section shall survive any termination of this Agreement. Coretec hereby acknowledges that the payment amount set out in this subparagraph is a payment of liquidated damages which is a pre-estimate of the damages which DDi will suffer or incur as a result of the event giving rise to such damages and the resultant non-completion of the Arrangement and the other Transactions contemplated herein and is not a penalty. Coretec hereby irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive.

18.

Termination:

(a)

This Agreement may be terminated by: (i) Coretec in the circumstances permitted by Section 16 hereof; or (ii) either Coretec or DDi if the Arrangement is not completed by the Completion Deadline.

(b)

This Agreement may be terminated by DDi if DDi is not in material breach of its obligations under this Agreement and Coretec breaches any of its representations, warranties, covenants or agreements contained in this Agreement, which breach would give rise to the failure of a condition set forth in Section 10 or 11.

(c)

Section 2.2 Arrangement

Commencing at the Effective Time, the following shall occur and shall be deemed to occur in the following order without any further act or formality:

(a)

Dissenting Shareholders. Each Common Share held by a Dissenting Shareholder shall be deemed to be transferred by the holder thereof, without any further act or formality on its part, free and clear of all Liens to DDi, in consideration for the fair value for each such Common Share held by such holder as determined and payable in accordance with Article 3 of this Plan of Arrangement.

(b)

(c)

Common Shares.

ARTICLE 3

RIGHTS OF DISSENT

Section 3.1 Rights of Dissent

Holders of Common Shares may exercise rights of dissent with respect to such Common Shares pursuant to and in the manner set forth in section 185 of the OBCA and this Section 3.1 (the “Dissent Rights”) in connection with the Arrangement; provided that, notwithstanding subsection 185(6) of the OBCA, the written objection to the Arrangement Resolution referred to in subsection 185(6) of the OBCA must be received by Coretec not later than 5:00 p.m. (Toronto time) on the second Business Day preceding the Coretec Meeting. Holders of the Common Shares who duly exercise such rights of dissent and who:

(a)

are ultimately determined to be entitled to be paid fair value for their Common Shares shall be deemed to have transferred such Common Shares to DDi in accordance with Section 2.2(a) hereof to the extent the fair value therefor is paid by DDi and will not be entitled to any other payment or consideration; or

(b)

are ultimately determined not to be entitled, for any reason, to be paid fair value for their Common Shares shall be deemed to have participated in the Arrangement on the same basis as a non-dissenting holder of Common Shares and shall receive the Consideration from DDi on the basis determined in accordance with Section 2.2(c) hereof,

but in no case shall Coretec, DDi or any other Person be required to recognize such holders as holders of Common Shares after the Effective Time, and the names of such holders of Common Shares shall be deleted from the registers of holders of Common Shares at the Effective Time.

ARTICLE 4

CERTIFICATES

Section 4.1 Common Shares, Coretec Options and Coretec DSUs

Prior to the Effective Date, DDi will deposit with the Depositary cash in an amount equal to the aggregate Consideration to be received by Coretec Shareholders pursuant Section 2.2 hereof payable in accordance with the provisions of Article 2 hereof.

As soon as practicable after the Effective Date, upon a Coretec Shareholder depositing with the Depositary certificates representing Common Shares accompanied by a duly-completed and executed Letter of Transmittal and such other documents and instruments as the Depositary may reasonably require, DDi shall cause the Depositary to deliver, to the applicable Coretec Shareholder in accordance with the Letter of Transmittal, a cheque representing the amount of Consideration such Coretec Shareholder is entitled to receive in accordance with the terms of the Arrangement less applicable withholdings.

On the Effective Date, DDi shall deliver, to the applicable Coretec Optionholder or holder of Coretec DSUs, a cheque representing the amount of Consideration such Coretec Optionholder or holder of Coretec DSUs is entitled to receive in accordance with the terms of the Arrangement less applicable withholdings.

On and after the Effective Time, certificates formerly representing Common Shares, Coretec Options and Coretec DSUs prior to the Effective Time (other than Common Shares held by DDi or any Affiliate thereof) shall cease to represent such securities and shall represent only the right to receive the Consideration therefor specified in Section 2.2 in accordance with the terms of the Arrangement, subject to compliance with the requirements set forth in this Article 4.

Section 4.2 Other Coretec Securities

At the Effective Time, each and every certificate, document, agreement or other instrument, if any, formerly representing any and all other Coretec Securities that represent or may be exercised for, or converted into, shares or other securities of Coretec shall be and shall be deemed to be cancelled, void and of no further force and effect without any further authorization, act or formality.

Section 4.3 Lost Certificates

If any certificate which immediately prior to the Effective Time represented outstanding Common Shares that were exchanged pursuant to Article 2 hereof, has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed, the Depositary will, subject to the terms hereof, issue in exchange for such lost, stolen or destroyed certificate, a cheque representing the amount of Consideration such Coretec Shareholder is entitled to in accordance with the terms of the Arrangement less applicable withholdings. When authorizing such issuance in exchange for any lost, stolen or destroyed certificate, the Person to whom such cheque is to be issued shall, as a condition precedent to the issuance thereof, give a bond satisfactory to the Depositary and DDi in such sum as DDi may reasonably direct or otherwise indemnify the Depositary, Coretec and DDi in a manner satisfactory to them against any claim that may be made against any of them with respect to the certificate alleged to have been lost, stolen or destroyed.

Section 4.4 Unclaimed Certificates

Notwithstanding any of the other provisions hereof, any certificate which immediately prior to the Effective Time represented outstanding Common Shares (other than Common Shares held by DDi or any affiliate thereof) that has not been surrendered with all other documents and instruments required by this Article 4 on or prior to the sixth anniversary of the Effective Date, shall cease to represent a claim or interest of any kind or nature against Coretec or DDi and the right of such Coretec Shareholder to receive payment of Consideration therefor, shall, on the sixth anniversary of the Effective Date, be deemed to have been surrendered and forfeited to DDi, together with all entitlements to dividends, distributions and any interest thereon held for such former Coretec Shareholder, for no consideration.

Section 4.5 Withholding Rights

DDi and the Depositary shall be entitled to deduct and withhold from any consideration payable to any Coretec Securityholder pursuant to Section 2.2 hereof, such amounts as DDi or the Depositary is required to deduct and withhold with respect to such payment under applicable Laws. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the Coretec Securityholder in respect of which such deduction and withholding was made.

ARTICLE 5

AMENDMENTS

Section 5.1 Amendments to Plan of Arrangement

Coretec reserves the right to amend, modify and/or supplement this Plan of Arrangement at any time and from time to time prior to the Effective Date, provided that each such amendment, modification and/or supplement must be (i) set out in writing, (ii) approved by DDi, (iii) filed with the Court and, if made following the Coretec Meeting, approved by the Court and (iv) communicated to the affected Coretec Shareholders and Coretec Optionholders.

Any amendment, modification or supplement to this Plan of Arrangement may be proposed by Coretec at any time prior to the Coretec Meeting (provided that DDi shall have consented thereto) with or without any other prior notice or communication, and if so proposed and accepted by the Coretec Shareholders and Coretec Optionholders voting at the Coretec Meeting (other than as may be required under the Interim Order), shall become part of this Plan of Arrangement for all purposes.

Any amendment, modification or supplement to this Plan of Arrangement that is approved by the Court following the Coretec Meeting shall be effective only if (i) it is consented to by each of Coretec and DDi and (ii) if required by the Court, it is communicated to or consented to by the Coretec Shareholders and Coretec Optionholders.

Any amendment, modification or supplement to this Plan of Arrangement may be made following the Effective Date unilaterally by DDi, provided that it concerns a matter which, in the reasonable opinion of DDi, is of an administrative nature required to better give effect to the implementation of this Plan of Arrangement and is not adverse to the economic interest of any former Coretec Securityholder.

ARTICLE 6

FURTHER ASSURANCES

Section 6.1 Further Assurances

SCHEDULE A

Representations and Warranties of Coretec

Coretec represents and warrants to and in favour of DDi as follows:

(a)

Organization. Each of Coretec and its Subsidiaries has been incorporated, is validly subsisting and has full corporate or legal power and authority to own its property and assets and to conduct its business as currently owned and conducted. Each of Coretec and its Subsidiaries is registered, licensed or otherwise qualified as an extra-provincial corporation or a foreign corporation in each jurisdiction where the nature of the business or the location or character of the property and assets owned or leased by it requires it to be so registered, licensed or otherwise qualified, other than those jurisdictions where the failure to be so registered, licensed or otherwise qualified would not have a Material Adverse Effect on Coretec. All of the outstanding shares of Coretec and its Subsidiaries are duly authorized, validly issued, fully paid and non-assessable (and, where required, properly registered). All of the outstanding shares of the Coretec Subsidiaries are owned directly or indirectly by Coretec or a Coretec Subsidiary. Except as set out in the Coretec Disclosure Letter and except pursuant to restrictions on transfer contained in the articles or by-laws (or their equivalent) of the applicable Coretec Subsidiary, the outstanding securities of the Coretec Subsidiaries are owned free and clear of all Encumbrances and neither Coretec nor any of the Coretec Subsidiaries is liable to any person in respect thereof. Except as disclosed in the Coretec Disclosure Letter, there are no outstanding options, rights, entitlements, understandings or commitments (contingent or otherwise) regarding the right to acquire any issued or unissued securities of any of the Coretec Subsidiaries by either Coretec or any of the Coretec Subsidiaries.

(b)

Capitalization. Coretec is authorized to issue an unlimited number of Common Shares. As at November 23, 2009, there were 18,021,807 Common Shares outstanding and an aggregate of 1,382,500 Common Shares were set aside for issue under the Coretec Share Option Plans. The Coretec Options and Coretec DSUs are disclosed in the Coretec Disclosure Letter. Except for the Coretec Options there are no options, warrants, conversion privileges or other securities, rights, agreements, arrangements or commitments (pre-emptive, contingent or otherwise) obligating Coretec or any of the Coretec Subsidiaries to issue or sell any shares of Coretec or any of the Coretec Subsidiaries or any securities or obligations of any kind convertible into or exchangeable for any shares of Coretec or any of the Coretec Subsidiaries. There are no outstanding bonds, debentures or other evidences of indebtedness of Coretec or any of its Subsidiaries having the right to vote with the Coretec Shareholders on any matter. There are no outstanding contractual obligations of Coretec or of any of the Coretec Subsidiaries to repurchase, redeem or otherwise acquire any outstanding Common Shares or with respect to the voting or disposition of any outstanding Common Shares. The Shareholder Rights Plan Agreement of Coretec dated March 28, 2003 has not been subsequently approved by the shareholders of Coretec and accordingly has terminated and is no longer in effect.

(c)

Authority. Coretec has all necessary power, authority and capacity to enter into this Agreement and all other agreements and instruments to be executed by Coretec as contemplated by this Agreement, and to perform its obligations hereunder and under such other agreements and instruments. The execution and delivery of this Agreement by Coretec and the completion by Coretec of the Arrangement and the other Transactions contemplated by this Agreement have been authorized by the directors of Coretec and, subject to the approval by the Coretec Shareholders and Coretec Optionholders in the manner contemplated herein, no other corporate proceedings on the part of Coretec are necessary to authorize this Agreement or to complete the Arrangement and the other Transactions contemplated herein. This Agreement has been executed and delivered by Coretec and constitutes a legal, valid and binding obligation of Coretec, enforceable against Coretec in accordance with its terms, subject to bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium and other applicable Laws relating to or affecting creditors’ rights generally, and to general principles of equity. The execution and delivery by Coretec of this Agreement and the performance by it of its obligations hereunder and the completion of the Arrangement and the other Transactions contemplated hereby, do not and will not:

(i)

result in a violation, contravention or breach of, require any consent to be obtained under or give rise to any termination rights under any provision of,

(A)

the articles or by-laws (or their equivalent) of Coretec or any of the Coretec Subsidiaries,

(B)

except for the consents, waivers, permits, exemptions, orders or approvals of, and any registrations and filings with, any Governmental Entity contemplated in Section 10(d) or any Laws, or

(C)

except as disclosed in the Coretec Disclosure Letter, any material contract, agreement, licence or permit to which Coretec or, any of the Coretec Subsidiaries, is bound or is subject or of which Coretec or any Coretec Subsidiary is the beneficiary;

(ii)

except as disclosed in the Coretec Disclosure Letter, give rise to any right of termination or acceleration of any material indebtedness, or cause any material indebtedness owing by Coretec or any of the Coretec Subsidiaries, to come due before its stated maturity or cause any available credit to cease to be available;

(iii)

result in the imposition of any material Encumbrance upon any of the property or assets of Coretec, any of the Coretec Subsidiaries, or restrict, hinder, impair or limit the ability of Coretec or, any of the Coretec Subsidiaries, to conduct the business of Coretec or any of the Coretec Subsidiaries; or

(iv)

except as disclosed in the Coretec Disclosure Letter, result in any payment (including termination, severance, unemployment compensation, change of control, “golden parachute”, bonus or otherwise) becoming due to any Employee, director or officer of Coretec or of any Coretec Subsidiary or increase any benefits otherwise payable under any Employee Plan or result in the acceleration of the time of payment or vesting of any such benefits;

No consent, approval, order or authorization of, or declaration or filing with, or waiver of any right of, any Governmental Entity or other person is required to be obtained or made by Coretec or, any of the Coretec Subsidiaries in connection with the execution and delivery of this Agreement or the consummation by Coretec of the Arrangement and the other Transactions contemplated herein other than (i) any approvals required pursuant to orders made by the Court, (ii) filings with the Director under the OBCA and filings with and approvals required by Securities Authorities and stock exchanges, and (iii) any other consent, waiver, permit, order or approval referred to in the Coretec Disclosure Letter which, if not obtained, would have a Material Adverse Effect on Coretec. Without limiting the generality of the foregoing, subject to obtaining the Coretec Required Vote at the Coretec Meeting, Coretec has complied with the requirements of the Rules.

(d)

Directors’ Approvals. The directors of Coretec present at a meeting have received an oral opinion from Capital Canada Limited, the financial advisor to the special committee of the board of directors of Coretec, that the Consideration is fair, from a financial point of view, to the Coretec Shareholders, the holders of Coretec Options and the holders Coretec DSUs and have unanimously:

(i)

determined that the Consideration is fair to the Coretec Shareholders and the Arrangement is in the best interests of Coretec;

(ii)

recommended that the Coretec Shareholders vote the Common Shares beneficially owned or controlled by them in favour of the Arrangement Resolution; and

(iii)

authorized the entering into of this Agreement and the performance by Coretec of its obligations hereunder.

Such opinion will be confirmed in writing and included in the Coretec Proxy Circular and the cost for such opinion is as set out in the Coretec Disclosure Letter.

(e)

Coretec Subsidiaries. All of the Subsidiaries of Coretec are set out in the most recently filed annual information form of Coretec, except as set out in the Coretec Disclosure Letter.

(f)

No Defaults.
