In the event of any income tax assessment or reassessment (the Tax Notice) against either the Corporation or the Acquiror with respect to the Original Consideration Shares (as consideration for the acquisition of the rights granted to and acquired by the Acquiror pursuant to the Original Agreement) or with respect to the New Consideration Shares (as consideration for the acquisition of the additional rights granted to and acquired by the Acquiror pursuant to this Agreement) which adjusts:

(a)

the Cost Amount;

(b)

the Elected Amount; or

(c)

the Fair Market Value,

of the Carbon Fibre Technology or the additional rights granted by the Corporation to the Acquiror in connection with this Agreement, as the case may be, then the Party so assessed or reassessed (the First Party) shall immediately give notice to the other Party of the Tax Notice. At the same time the First Party shall indicate whether or not the First Party will pursue a conscientious objection to the Tax Notice. In the event that the First Party does not propose to pursue such objection to the Tax Notice, the other Party shall have 30 days from the receipt of the notice to advise the First Party of its desire to oppose the Tax Notice (the Objecting Party). In that event, the Objecting Party shall have full authority to conscientiously prosecute an objection on behalf of the First Party and the First Party agrees to cooperate fully in respect of such objection, including the filing of documents, attendance at meetings and doing such other acts and things as may reasonably be required by the Objecting Party.

4.5 In the event that:

(a)

no Party seeks to pursue an objection to the Tax Notice;

(b)

all appeal rights in respect of the Tax Notice have expired without appeals having been taken; or

(c)

a court or tribunal having jurisdiction in the matter has decided to uphold the determination contained in the Tax Notice or has decided that the Cost Amount or the Fair Market Value is an amount (the Court Determined Amount) which is equal to neither the amount set out in the Tax Notice nor value of the Original Consideration Shares or the additional rights granted by the Corporation to the Acquiror in connection with this Agreement, as the case may be, and: (i) all appeal rights in respect of such decision have been exhausted or have expired without appeals having been taken; or (ii) the Parties agree with such decision,

then the Cost Amount, the Elected Amount, or the Fair Market Value, as the case may be, of the relevant property or properties set forth in the Tax Notice or, where the Court Determined Amount is different than the amount set forth in the Tax Notice, the Court Determined Amount, shall constitute the Cost Amount, the Elected Amount, or the Fair Market Value of the relevant property or properties in question, so as to effect an automatic adjustment in the Elected Amount or the value of the Original Consideration Shares and/or the New Consideration Shares, as the case may be, if necessary and appropriate. If relevant, the consideration as represented by the Original Consideration Shares and/or the New Consideration Shares shall be adjusted in accordance with the Articles of Incorporation of the Acquiror as registered with the Registrar of Corporations in the Province of Alberta.

4.6 Should an objection to the Tax Notice be initially pursued and the Objecting Party wishes to abandon further pursuit by terminating any negotiations, by accepting a settlement proposal with the Canada Revenue Agency, or by not appealing a judgment of a court of competent jurisdiction, or by any other means whatever, then such Objecting Party shall give full details and immediate notice (Notice to Desist) to the other Party. If within 20 days of receipt of the Notice to Desist, the other Party fails to deliver a notice of its desire to continue such objection (Notice to Continue), then the Objecting Party shall be entitled to consummate the settlement proposal with the Canada Revenue Agency, adopt a judgment, or abandon any further pursuit of the matter. In that event, the Cost Amount, the Elected Amount, or the Fair Market Value as thus determined shall be the Elected Amount (if necessary and appropriate) or amount of the Original Consideration Shares and/or New Consideration Shares, as the case may be. The value of the Original Consideration Shares and/or the New Consideration Shares, as the case may be, shall be adjusted as required. Should a Notice to Continue be delivered as aforesaid by the other Party, the provisions of this paragraph shall apply mutatis mutandis thereto.

4.7 It is the intention of the Parties that the transaction contemplated by the Original Agreement and this Agreement take place on a tax-deferred basis, such that no capital gains shall be realized by the Corporation on its disposition of the Carbon Fibre Technology pursuant to the Original Agreement and that no capital gains shall be realized by the Corporation on its disposition of the additional rights granted to the Acquiror in connection with this Agreement, and this Article 4 shall be interpreted on such basis. For greater certainty, unless otherwise agreed between the Parties, where the application of this Article 4 results in an adjustment to the Cost Amount of the relevant property in question, the Elected Amount shall, if reasonable or appropriate, be adjusted on a retroactive basis to be equal to such amount as would give effect to the joint intention expressed in this Article 4, and either the Corporation and the Acquiror may make such filings as may be necessary to give effect to such adjustment to the Elected Amount.

5. Records and Audit.

5.1 Corporation is not required to maintain record(s) for the benefit of the Acquiror.
