Westaim shall promptly send or cause to be sent a letter to all parties who have entered into confidentiality agreements with it in connection with the process giving rise to this Agreement, requiring all materials provided to such parties by it to be destroyed or returned to it or its agents or advisors and shall use reasonable commercial efforts to ensure that such requests are honoured.
	(b)		Subject to Subsections 10.3(c), (d) and (e) below, Westaim shall not, directly or indirectly, through any of its Subsidiaries or through any officer, director, employee, investment banker, lawyer or other representative or agent of it or any of its Subsidiaries:

	(ii)		participate in any discussions or negotiations regarding an Acquisition Proposal;

	(v)		waive any provisions of or release or terminate any confidentiality or standstill agreement between it and any Person relating to an actual or potential Acquisition Proposal, or amend any such agreement or consent to the making of an Acquisition Proposal in accordance with the terms of such agreement; or
	(vi)		accept, recommend, approve or enter into or propose publicly to accept, recommend, approve or enter into any agreement, arrangement or understanding (other than a confidentiality agreement as permitted hereunder) related to any Acquisition Proposal.

(c) Notwithstanding Subsection 10.3(b) above, prior to the Time of Closing, Westaim and its officers, directors, employees, advisors or other representatives or agents may enter into, or participate in, any discussions or negotiations with a Person who seeks to initiate such discussions or negotiations and, subject to the entering into by such Person of a confidentiality agreement substantially similar to the Confidentiality Agreement, may furnish to such Person information concerning it and its business, properties and assets, in each case if, and only to the extent that:

	(i)		such Person has first made an unsolicited bona fide Acquisition Proposal which the Westaim Board determines in good faith (after consultation with its financial advisors) would, if consummated in accordance with its terms, be reasonably likely to result in, a Superior Proposal;
	(ii)		the Westaim Board, after receiving the advice of outside legal counsel, has determined in good faith that the failure to take such action would be inconsistent with its fiduciary duties; and
	(iii)		it has provided to the Companies the information required to be provided under Subsections 10.3(d) and (e) in respect of such Acquisition Proposal and has promptly notified the Companies in writing of the determinations in paragraphs 10.3(c)(i)and (ii) above.

(d) Westaim shall promptly notify the Companies, at first orally and then in writing, of any Acquisition Proposal received after the date hereof, or any confidentiality agreement entered into in respect of any such Acquisition Proposal and any inquiry or contact

- 59 -

received after the date hereof that could reasonably be expected to lead to an Acquisition Proposal, or any request for non-public information relating to it received after the date hereof or for access to its properties, books or records by any Person that informs it that it is considering making, or has made, an Acquisition Proposal after the date hereof; which notice will include any known terms and conditions of such Acquisition Proposal (including any form of agreement proposed to be entered into) and shall indicate such details, to the extent known, of the Acquisition Proposal, inquiry or contact as the Companies may reasonably request, including the identity of the Person making such proposal, inquiry or contact. Westaim shall keep the Companies informed of the status, including any change to the material terms, of any such Acquisition Proposal or inquiry. In addition, Westaim shall provide the Companies with access to any information provided to any such Person in respect of which a confidentiality agreement is entered into in respect of any Acquisition Proposal which has not already been provided to the Companies.

	(e)		Westaim shall promptly give the Companies orally and in writing, notice of any determination by the Westaim Board that a bona fide Acquisition Proposal constitutes a Superior Proposal, shall identify the Person making the Superior Proposal and shall provide a true and complete copy thereof and any amendments thereto. For a period of three (3) Business Days after providing notice of such determination by the Westaim Board, Westaim agrees not to accept, recommend, approve or enter into any agreement to implement such Superior Proposal and shall not withdraw, modify or change its recommendation in respect of the Reorganization. In addition, during such three (3) Business Day period, Westaim shall, and shall cause its financial and legal advisors to, negotiate in good faith with the Companies and their financial and legal advisors, to make such adjustments in the terms and conditions of this Agreement as would enable Westaim to proceed with the Reorganization as amended rather than the Superior Proposal. In the event the Companies propose to amend this Agreement to provide that the Westaim Shareholders shall receive a value per share equal to or having a value greater than the value per share provided in the Superior Proposal and so advise the Westaim Board prior to the expiry of such three (3) Business Day period, the Westaim Board shall not accept, recommend, approve or enter into any agreement to implement such Superior Proposal and shall not release the party making the Superior Proposal from any standstill provisions and shall not withdraw, modify or change its recommendation in respect of the Reorganization. If the Westaim Board continues to believe that such Superior Proposal remains a Superior Proposal and therefore rejects the Companies’ amended proposal, Westaim may terminate this Agreement, provided however, that Westaim must pay to the Companies the non-completion fee described in Section 10.4 with such termination. In the event that Westaim provides the Companies with a copy of the notice referred to in this Subsection 10.3(e) on a date that is less than three (3) Business Days prior to the Westaim Meeting, Westaim shall adjourn the Westaim Meeting to a date that is not less than three (3) Business Days and not more than 10 Business Days after the date of the notice.
	(f)		Nothing contained in this Section 10.3 or any other provision of this Agreement shall prohibit the Westaim Board from: (i) making any disclosure of an Acquisition Proposal to the Westaim Shareholders prior to the Time of Closing if, in the good faith judgment of such board of directors after receiving the advice of outside counsel, such disclosure is necessary for the board of directors to act in a manner consistent with its fiduciary duties or is otherwise required under applicable law; (ii) taking any other action with regard to an Acquisition Proposal to the extent ordered or otherwise mandated by any court of

- 60 -

competent jurisdiction; (iii) providing information to or otherwise dealing and negotiating with Persons including potential investors and potential agents and underwriters in respect of the Equity Financing; and (iv) providing information to, soliciting offers from or entering into or continuing negotiations or discussions with any third Person with respect to offers to purchase the assets of iFire and 1294339 Ontario Inc. and the shares of iFire IP Corporation and Westaim may accept any such offers and sell or enter into agreements to sell such assets or shares at any time provided that Westaim shall promptly advise the Companies of the existence and terms of any proposal or offer in respect thereof received by Westaim and subject to the Companies’ approval thereof, such approval not to be unreasonably withheld.

	(g)		Westaim also acknowledges and agrees that each successive material modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of the requirement under Subsection 10.3(e) to initiate an additional three (3) Business Day notice period.
	(h)		The Companies agree that all information that may be provided to it by Westaim, as the case may be, with respect to any Acquisition Proposal pursuant to this Section 10.3 shall be treated as if it were “Information” as that term is defined in the Confidentiality Agreement and shall not be disclosed or used except in accordance with the provisions of the Confidentiality Agreement or in order to enforce its rights under this Agreement in legal proceedings.

Section 10.4 Westaim Non-Completion Fee.

     If, at any time after the execution of this Agreement and prior to the termination of this Agreement pursuant to Article 12 (provided there is no material breach or non-performance by the Companies of a material provision of this Agreement):

	(a)		the Westaim Board fails to make or withdraws, qualifies or changes any of its recommendations, approvals or determinations referred to in Sections 4.5 and 10.2 or publicly proposes to do any of the foregoing, in a manner adverse to the Companies or resolves to do so prior to the Time of Closing;
	(b)		Westaim recommends, approves or enters into or proposes publicly to accept, recommend, approve or enter into any agreement with any Person to implement a Superior Proposal subject to compliance with Section 10.3;
	(c)		an Acquisition Proposal is publicly announced, proposed, offered or made to the Westaim Shareholders prior to the date of the Westaim Meeting and (i) such Acquisition Proposal has not expired or been withdrawn at the time of the Westaim Meeting and (ii) the Westaim Shareholders do not approve the Westaim Reorganization Resolutions and (iii) such Acquisition Proposal is completed within nine months of the termination of this Agreement; or
	(d)		Westaim shall have taken any action or have failed to take any action that results in Westaim being in breach of any of its covenants, agreements, representations or warranties made in this Agreement (without giving effect to any materiality qualifiers contained therein) which breach individually or in the aggregate causes or would reasonably be expected to cause a Material Adverse Change in respect of Westaim and the Westaim Subsidiaries (taken as a whole) or materially impede the completion of the Reorganization, and Westaim fails to cure such breach within five (5) Business Days

- 61 -

after receipt of written notice thereof from the Companies (except that no cure period shall be provided for a breach which by its nature cannot be cured and, in no event, shall any cure period extend beyond the Outside Date);

(each of the above being a “Westaim Payment Event”), then in the event of the termination or contemplated termination (in the case of Section 12.2(j)) of this Agreement pursuant to Article 12, Westaim shall pay to the Companies $2,250,000 as a non-completion fee in immediately available funds to an account designated by the Companies within two (2) Business Days after the first to occur of any one of such Westaim Payment Events. Following a Westaim Payment Event, but prior to payment of the non-completion fee, Westaim shall be deemed to hold such payment in trust for the Companies. For greater certainty, the Parties agree that any payment of the non-completion fee by Westaim pursuant to this Section 10.4 is a payment of liquidated damages which are a genuine pre-estimate of the damages that the Companies will suffer or incur as a result of the event giving rise to such damages and the resultant termination of this Agreement and are not penalties. Each Party irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. The Companies agree that the payment made pursuant to Section 10.4 is the sole monetary remedy of the Companies in respect of any breach of this Agreement by Westaim; provided, however, that any payment made pursuant to Section 10.4 hereof shall be without prejudice to the rights and remedies available to the Companies in respect of any claim based on the fraud or wilful misconduct of Westaim, including, without limitation, an intentional breach of Section 10.3. Westaim shall only be obligated to pay one non-completion fee under this Section 10.4.

Section 10.5 Covenants of Arcticor, Plumb-Line and PLMG.

	(a)		Each of Arcticor, Plumb-Line and PLMG hereby agree until the earlier of the Effective Date and the termination of this Agreement pursuant to Article 12 not to, except in connection with the Equity Financing including potential investors therein and potential agents or underwriters thereof (and in such event on terms acceptable to Westaim), provide information to, solicit offers from, or enter into or continue negotiations or discussions with any third party with respect to any transaction in the nature of the Transactions, whether by way of a sale of Arcticor (that would also include Nascor), Nascor, Plumb-Line or PLMG or by way of the sale of a substantial or majority interest in the Nascor Securities or Plumb-Line Securities or PLMG Securities, or any business combination transaction involving Arcticor (that would also include Nascor), Nascor, Plumb-Line or PLMG including, in each case and without limitation, by way of a sale of securities or assets or a merger, amalgamation, plan of arrangement or other means.
	(b)		The Companies acknowledge that the Westaim Supporting Shareholders have entered into the Support Agreements in their capacity as Westaim Shareholders and that having done so does not derogate from the discharging of their duties as directors and/or officers of Westaim. It is further acknowledged that nothing contained herein or in the Support Agreements shall prevent any director or officer of Westaim from discharging his or her legal or fiduciary obligations as a director or officer, subject to compliance with this Agreement.
	(c)		If, at any time after the execution of this Agreement and prior to the termination of this Agreement pursuant to Article 12 (provided there is no material breach or non-performance by Westaim of a material provision of this Agreement), the Companies shall have taken any action or have failed to take any action that results in any of the Companies being in breach of any of their respective covenants, agreements, representations or warranties made in this Agreement (without giving effect to any materiality qualifiers contained therein) which breach individually or in the aggregate

- 62 -

causes or would reasonably be expected to cause a Material Adverse Change in respect of Plumb-Line and the Plumb-Line Subsidiaries (taken as a whole), Nascor or PLMG or materially impede the completion of the Reorganization, and the Companies fail to cure such breach within five (5) Business Days after receipt of written notice thereof from Westaim (except that no cure period shall be provided for a breach which by its nature cannot be cured and, in no event, shall any cure period extend beyond the Outside Date) (a “Company Payment Event”), then in the event of the termination or contemplated termination (in the case of Section 12.2(l)) of this Agreement pursuant to Article 12, the Companies shall pay to Westaim $2,250,000 as a non-completion fee in immediately available funds to an account designated by Westaim within two (2) Business Days after the occurrence of such Company Payment Event. Following a Company Payment Event, but prior to payment of the non-completion fee, the Companies shall be deemed to hold such payment in trust for Westaim. For greater certainty, the Parties agree that any payment of the non-completion fee by the Companies pursuant to this Section 10.5(c) is a payment of liquidated damages which are a genuine pre-estimate of the damages that Westaim will suffer or incur as a result of the event giving rise to such damages and the resultant termination of this Agreement and are not penalties. Each Party irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. Westaim agrees that the payment made pursuant to this Section 10.5(c) is the sole monetary remedy of Westaim in respect of any breach of this Agreement by the Companies; provided, however, that any payment made pursuant to this Section 10.5(c) shall be without prejudice to the rights and remedies available to Westaim in respect of any claim based on the fraud or wilful misconduct of the Companies. The Companies shall only be obligated to pay one non-completion fee under this Section 10.5(c).

	(d)		If Plumb-Line completes the A&K Spinout, the definitive agreement in respect of the A&K Spinout will contain industry standard representations, warranties and covenants consistent with transactions of similar nature conducted in the Province of Alberta. Plumb-Line will provide Westaim the ability to review the definitive agreement in respect of the A&K Spinout and shall consult with Westaim prior to the execution thereof.
	(e)		Plumb-Line shall not and shall cause its Subsidiaries to not amend any material definitive agreements in respect of the Asty Acquisition, the F&D Acquisition or the Four Star Acquisition without the prior consent of Westaim, such consent not to be unreasonably withheld.
	(f)		The Companies shall use all reasonable commercial efforts to ensure that, prior to October 15, 2008, Westaim shall have received PLMG Lock-up Agreements, duly executed by each of the PLMG Shareholders in respect of all PLMG Securities owned or to be owned by such person, directly or indirectly, or over which control or direction is or will be exercised by such person which shall, in the aggregate, represent not less than 100% of the PLMG Securities issued and outstanding at the Effective Time, and none of such agreements shall have been terminated by any PLMG Shareholder.
	(g)		The Companies shall use all reasonable commercial efforts to ensure that, prior to October 15, 2008, Westaim shall have received Four Star Lock-up Agreements, duly executed by each of the Four Star Securityholders in respect of all Plumb-Line Holdings LP Securities owned or to be owned by such person, directly or indirectly, or over which control or direction is or will be exercised by such person at the Effective Time, and none of such agreements shall have been terminated by any Four Star Securityholder.

	(b)		The Parties acknowledge that certain information received pursuant to Subsection 10.6(a) will be non-public or proprietary in nature and that such Parties shall not disclose such information to third parties without the prior written consent of the other Party unless required to do so by Law.

EXERCISE OF THE WARRANT

          The right to purchase LP Units conferred by the Warrant Certificate may be exercised, prior to the Expiry Time, by the holder surrendering it, with a duly completed and executed exercise form substantially in the form attached hereto as Schedule “B” and cash or a certified cheque payable to or to the order of the Partnership, at par in Calgary, Alberta, for the purchase price applicable at the time of surrender in respect of the LP Units subscribed for in lawful money of Canada, to the Partnership.

3.2 Effect of Exercise of the Warrant

(a) Upon surrender and payment as aforesaid the LP Units so subscribed for shall be issued as fully paid and non-assessable units, free from all liens, charges and encumbrances and the holder shall become the holder of record of such LP Units on the date of such surrender and payment;

(b)		Within five business days after surrender and payment as aforesaid, the Partnership shall forthwith cause the issuance of and make available for pick-up or, at the request of the holder, mail to the holder, a certificate for the LP Units purchased as aforesaid; and
(c)		Notwithstanding anything herein contained including any adjustment provided for in Article 4, the Partnership shall not be required, upon the exercise of any Warrants, to issue fractions of LP Units or to distribute certificates which evidence fractional LP Units. In lieu of fractional LP Units, there shall be paid to the holder by the Partnership upon surrender of Warrant Certificate(s) for exercise of Warrants pursuant to Section 3.1 within ten (10) business days after the exercise date, an amount in lawful money of Canada equal to the then Current Market Value of such fractional interest, provided that the Partnership shall not be required to make any payment, calculated as aforesaid, that is less than $5.00.

3.3 Subscription for Less than Entitlement

          The holder may subscribe for and purchase a number of LP Units less than the number which it is entitled to purchase pursuant to the surrendered Warrant Certificate.

3.4 Expiration of the Warrant

          After the Expiry Time all rights hereunder shall wholly cease and terminate and the Warrant shall be void and of no effect.

ARTICLE 4
ADJUSTMENTS

4.1 Adjustments

          The purchase rights in effect at any date attaching to the Warrants shall be subject to adjustment from time to time as follows:

(a) If and whenever after the date hereof and at any time prior to the Expiry Time, the Partnership shall:

	(i)		subdivide, redivide or change the outstanding LP Units into a greater number of LP Units;
	(ii)		consolidate, reduce or combine the outstanding LP Units into a lesser number of LP Units;
	(iii)		issue LP Units (or securities convertible into LP Units) to all or substantially all of the holders of outstanding LP Units by way of a distribution of LP Units or securities convertible into LP Units (other than Distributions Paid in the Ordinary Course);

the Exercise Price in effect on the effective date of such subdivision, redivision, change, reduction, combination or consolidation, or on the record date of such distribution of securities of the Partnership, as the case may be, shall be adjusted to equal the price determined by multiplying the Exercise Price in effect immediately prior to such effective date or record date by a fraction of which the numerator shall be the total number of LP Units outstanding immediately prior to such date and the denominator shall be the total number of LP Units outstanding immediately after such date (including, in the case where securities convertible into or exchangeable LP Units are issued, the number of LP Units that would have been outstanding had such securities been converted or exchanged for LP Units on such record date). Such adjustment shall be made successively whenever any event referred to in this subsection (a) shall occur, and any such issue of LP Units by way of a distribution shall be deemed to have been made on the record date for the distribution for the purpose of calculating the number of outstanding LP Units under subsections (b) and (c) of this Section.

Upon any adjustment of the Exercise Price pursuant to this subsection (a), the number of LP Units subject to the right of purchase under each Warrant not previously exercised shall be contemporaneously adjusted by multiplying the number of LP Units which theretofore may have been purchased under such Warrant by a fraction of which the numerator shall be the respective Exercise Price in effect immediately prior to such adjustment and the denominator shall be the respective Exercise Price resulting from such adjustments.

(b)		If and whenever at any time after the date hereof and prior to the Expiry Time, the Partnership shall fix a record date for the distribution to all or substantially all of the holders of LP Units of rights, options or warrants (other than the Warrants) entitling them for a period expiring not more than forty-five (45) days after such record date to subscribe for or purchase LP Units (or securities convertible into LP Units) at a price (or having a conversion price or exchange price) less than 95% of the Current Market Price on such record date, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of LP Units outstanding on such record date plus the number arrived at by dividing the aggregate price of the total number of additional LP Units offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible securities so offered) by such Current Market Price, and of which the denominator shall be total number of LP Units outstanding on such record date plus the total number of additional LP Units offered for subscription or purchase (or into which the convertible securities so offered are convertible or exchangeable); any LP Units owned by or held for the account of the Partnership or any subsidiary (as defined in the Business Corporations Act (Alberta), of the Partnership shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that any rights, options or warrants are not so issued or any such rights, options or warrants are not exercised prior to the expiration thereof, the Exercise Price shall then be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based upon the number and aggregate price of LP Units (or securities convertible into LP Units) actually issued upon the exercise of such rights, options or warrants, as the case may be.
(c)		If and whenever at any time after the date hereof and prior to the Expiry Time, the Partnership shall fix a record date for the making of a distribution to all or substantially all the holders of its outstanding LP Units of:

	(i)		units of any class other than LP Units, whether of the Partnership or any other entity (other than units distributed as Distributions Paid in the Ordinary Course);
	(ii)		rights, options or warrants to subscribe for or purchase LP Units (or other securities convertible into LP Units) (excluding (A) those referred to in subsection (b), and (B) those described in subsection (b) but exercisable for a period not more than forty-five (45) days after such record date exercisable at a price per unit (or having a conversion or exchange price per unit) not less than 95% of the Current Market Price);
	(iii)		evidence of its indebtedness; or
	(iv)		assets (excluding Distributions Paid in the Ordinary Course);

then, and in each such case, the Exercise Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Exercise Price in effect on such record date by a fraction, of which the numerator shall be the total number of LP Units outstanding on such record date multiplied by the Current Market Price on such record date, less the aggregate fair market value (as determined by the directors of the General Partner, acting reasonably, which determination shall be conclusive) of such units, rights, options, warrants, evidence of indebtedness or assets so distributed, and of which the denominator shall be the total number of LP Units outstanding on such record date multiplied by such Current Market Price; any LP Units owned by or held for the account of the Partnership or any subsidiary (as defined in the Business Corporations Act (Alberta)) of the Partnership shall be deemed not to be outstanding for the purpose of any such computation; such adjustment shall be made successively whenever such a record date is fixed; to the extent that such distribution is not so made, the Exercise Price shall then be readjusted to the Exercise Price which would then

	be in effect if such record date had not been fixed or to the Exercise Price which would then be in effect based upon such units, rights, options, warrants, evidences of indebtedness or assets actually distributed, as the case may be.
(d)		If and whenever at any time after the date hereof and prior to the Expiry Time, there is a reclassification of the LP Units or a capital reorganization of the Partnership other than as described in paragraph (a) or a consolidation, amalgamation or merger of the Partnership (including, without limitation, by way of plan of arrangement) with or into any other body corporate, trust, partnership, limited partnership or other entity, or a sale or conveyance of the property and assets of the Partnership as an entirety or substantially as an entirety to any other body corporate, trust, partnership, limited partnership or other entity, any Warrantholder who has not exercised his right of acquisition prior to the effective date of such reclassification, reorganization, consolidation, amalgamation, merger, sale or conveyance, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of LP Units then sought to be acquired by it, the kind and number of units or other securities or property of the Partnership or of the body corporate, trust, partnership, limited partnership or other entity resulting from such merger, reclassification, reorganization, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such holder would have been entitled to receive as a result of such reorganization, consolidation, amalgamation, merger, sale or conveyance, if, on the record date or the effective date thereof, as the case may be, the Warrantholder had been the registered holder of the number of LP Units to which the holder was theretofore entitled upon exercise. If determined appropriate by the board of directors of the General Partner to give effect to or to evidence the provisions of this subsection (d), the Partnership, its successor, or such purchasing body corporate, trust, partnership, limited partnership or other entity, as the case may be, shall prior to or contemporaneously with any such reclassification, reorganization, consolidation, amalgamation, merger, sale or conveyance, enter into an agreement or new Warrant Certificate which shall provide, to the extent possible, for the application of the provisions set forth in this Warrant with respect to the rights and interests thereafter of the Warrantholders to the end that the provisions set forth in this Warrant shall thereafter correspondingly be made applicable, as nearly as may reasonably be, with respect to any units, other securities or property to which a Warrantholder is entitled on the exercise of its acquisition rights thereafter and upon entering into such new Warrant Certificate or agreement, the Partnership shall cease to have any obligations (including the obligation to issue any LP Units) hereunder and the holder shall cease to have any rights hereunder. Any Warrant Certificate or agreement entered into pursuant to the provisions of this subsection (d) shall be an agreement entered into pursuant to the provisions of Article 6. Any Warrant Certificate or agreement entered into between the Partnership, any successor to the Partnership or such purchasing body corporate, trust, partnership, limited partnership or other entity shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 4.1 and which shall apply to successive reclassifications, reorganizations, amalgamations, consolidations, mergers, sales or conveyances.
(e)		If necessary, appropriate adjustments shall be made in the application of the provisions set forth in this Section 4.1 with respect to the rights and interest thereafter of the holders of Warrants to the end that the provisions set forth in this Article 4 shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any units or other securities or property thereafter deliverable upon the exercise of any Warrant. Any such adjustments shall be made by and set forth in an amendment to this Warrant Certificate hereto approved by the directors of the General Partner and shall for all purposes conclusively be deemed to be an appropriate adjustment. The subdivision or consolidation of the LP Units at any time outstanding into a greater or lesser number of LP Units shall be deemed not to be a reclassification of the capital of the Partnership for the purposes of this subsection.
(f)		If any case in which this Section 4.1 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Partnership may defer, until the occurrence of such event, issuing to the holder of any Warrant exercised after such event the additional LP Units issuable upon such conversion by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Partnership shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional LP Units upon the occurrence of the event requiring such adjustment and the right to receive any distributions made on such additional LP Units

		declared in favour of holders of record of LP Units on and after the relevant date of exercise or such later date as such holder would, but for the provisions of this subsection (f), have become the holder of record of such additional LP Units pursuant to subsection (b).
(g)		If the purchase price provided for in any right, warrant or option issued as described in subsection (b) or (c) is decreased, or the price at which LP Units are issued as described in subsection (a) is decreased or the rate of conversion at which any convertible securities which are issued as described in subsection (a) is increased, the Exercise Price shall, subject to subsection (f), forthwith be changed so as to decrease the Exercise Price to such Exercise Price as would have been obtained had the adjustment made in connection with the issuance of all such rights, options or securities been made upon the basis of such purchase price as so decreased or such rate as so increased.
(h)		No adjustment in the Exercise Price or in the number of LP Units to be issued pursuant to the exercise of the Warrants shall be required unless such adjustment would result in a change of at least 1% in the Exercise Price then in effect or unless the number of LP Units to be issued would change by at least 1/100th of a unit, provided, however, that any adjustments which, except for the provisions of this subsection 4.1(h) would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustment.
(i)		No adjustment in the Exercise Price shall be made in respect of any event described in subsections 4.1(a)(iii), 4.1(b) or 4.1(c):

	(i)		if the Warrantholder is entitled to participate in such event on the same terms mutatis mutandis as if it had exercised its purchase rights prior to the effective date or record date of such event;
	(ii)		in respect to the issuance of LP Units on exercise of the Warrants; or
	(iii)		in respect of the issuance of LP Units pursuant to any incentive stock option or purchase plan for directors, officers, employees and\or consultants of the General Partner or the Partnership or any of their subsidiaries.

(j)		Upon the expiry of the period for conversion of convertible securities and the exercise period for rights, options or warrants (other than rights, options or warrants in respect of which the Warrantholders are entitled to participate, as contemplated in subsection 4.1(i)) to purchase LP Units or convertible securities, the Exercise Price shall be adjusted to what it would have been if such unconverted convertible securities and unexercised rights, options or warrants had not been issued.
(k)		The adjustments provided for in this Section in the Exercise Price and in the number and classes of units which are to be received on the exercise of Warrants are cumulative. After any adjustment pursuant to this Section, the term “LP Units” where used in this Warrant shall be interpreted to mean the units or other securities or property of the Partnership which, as a result of all prior adjustments pursuant to this Section, the Warrantholder is entitled to receive upon the exercise of his Warrant, and the number of LP Units indicated in any subscription made pursuant to a Warrant shall be interpreted to mean the number and kind of securities or property which, as a result of all prior adjustments pursuant to this Section, a Warrantholder is entitled to receive upon the full exercise of a Warrant entitling the holder thereof to purchase the number of LP Units so indicated.
(l)		All securities and property which a Warrantholder is at the time in question entitled to receive on the full exercise of his Warrant, whether or not as a result of adjustments made pursuant to this Section, shall, for the purposes of the interpretation of this Warrant be deemed to be securities and property which such Warrantholder is entitled to purchase pursuant to such Warrant.

4.2 Voluntary Adjustment by the Partnership

          Subject to requisite Exchange approval, the Partnership may, at its option, at any time prior to the Expiry Time, reduce the then current Exercise Price to any amount deemed appropriate by the board of directors of the General Partner.

4.3 Notice of Adjustment

          Whenever the number of LP Units purchasable upon the exercise of each Warrant or the Exercise Price of such LP Units is adjusted, as herein provided, the Partnership shall promptly send to the Warrantholder by first class mail, postage prepaid, notice of such adjustment or adjustments.

4.4 No Adjustment for Distributions

          Except as provided in section 4.1 of this Article 4, no adjustment in respect of any distributions shall be made during the term of a Warrant or upon the exercise of a Warrant.

4.5 Determination of Adjustments

          If any questions shall at any time arise with respect to the Exercise Price, such questions shall be conclusively determined by the Partnership’s Auditors, or, if they decline to so act, any other firm of chartered accountants that the Partnership may designate and the Warrantholder, acting reasonably, may approve, and who shall have access to all appropriate records and such determination shall be binding upon the Partnership and the holder.

4.6 Notice of Special Matters

          The Partnership covenants that, so long as any Warrants remain outstanding it will give notice to the Warrantholders of (i) its intention to fix a record date that is prior to the Expiry Date for any event referred to in subsections (a), (b) or (c) of Section 4.1 (other than subdivision, consolidated or reclassification of its LP Units) which may give rise to an adjustment in the number of LP Units to be received on exercise or the Exercise Price and (ii) its intention to complete a Liquidity Transaction and the actual completion thereof. Such notice shall specify the particulars of such event and the record date, if applicable, for such event, provided that the Partnership shall only be required to specify in the notice such particulars of the event as shall have been fixed and determined on the date on which the notice is given. The notice shall be given in each case not less than 10 days prior to such applicable record date or closing date of the Liquidity Transaction, as applicable.

4.7 No Action after Notice

          The Partnership covenants that it will not close its transfer books or take any other partnership action which might deprive the holder of the opportunity to exercise its right of acquisition pursuant thereto during the period of 10 days after the giving of the certificate or notices set forth in section 4.6.
