In case this Debenture shall become mutilated or be lost, stolen or destroyed, the Corporation, in its discretion, may issue and deliver, a new Debenture upon surrender and cancellation of the mutilated Debenture, or in the case of a lost, stolen or destroyed Debenture, in lieu of and in substitution for the same, and the substituted Debenture shall be in the form of this Debenture and be ranked equally in accordance with its terms with all other Debentures originally issued on the Issuance Date. In case of loss, theft or destruction the applicant for a substituted Debenture shall furnish to the Corporation such evidence of the loss, theft or destruction of this Debenture as shall be satisfactory to them in their discretion and shall also furnish an indemnity and surety bond satisfactory to them in their discretion along with any other documents that might be required by the Corporation.

(a)

This Debenture shall bear interest (i) from and including the Issuance Date, or (ii) from and including the last Interest Payment Date to which interest shall have been paid or on the outstanding principal amount of this Debenture, whichever shall be the later, to but excluding the next Interest Payment Date.

(b)

Interest for any period of less than six months shall be computed on the basis of a year of 360 days consisting of twelve 30-day months (the “deemed year”). Whenever interest is computed on the basis of the deemed year, interest shall be expressed as a yearly rate by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

2.4	Payment of Interest

The following provisions shall apply to this Debenture, except as otherwise provided in Section 2.1(a) or elsewhere in this Debenture or specified in a Board Resolution or an Officer’s Certificate relating to this Debenture:

(a)

As interest becomes due on this Debenture (except on conversion, at maturity or on redemption, when interest may at the option of the Corporation be paid upon surrender of this Debenture) the Corporation (which shall be confirmed by the Corporation by Officer’s Certificate pursuant to Section 2.1(c)) shall send or forward a check by prepaid ordinary mail, wire, electronic transfer of funds or such other means as may be agreed to by the Debentureholder and, if applicable, deliver the Shares, pursuant to Section 2.1(c), in payment of such interest to the order of the registered holder of such Debenture appearing on the registers maintained by the Corporation as at the close of business on the fifth Business Day prior to the applicable Interest Payment Date and addressed to the holder at the holder’s last address appearing on the register (or in the case of joint holders, to such address of one of the joint holders), unless such holder otherwise directs in writing to the Corporation in advance. If cash payment is made by check, such check shall be forwarded at least three days prior to the Interest Payment Date and if payment is made by other means (such as wire or electronic transfer of funds), such payment shall be made in a manner whereby the holder receives credit for such payment on the Interest Payment Date. The mailing of such check or the making of such payment by other means shall, to the extent of the sum represented thereby, satisfy and discharge all liability for interest on this Debenture, unless in the case of payment by check, such check is not paid at par on presentation. In the event of non-receipt of any check for or other payment of interest by the person to whom it is so sent as aforesaid, the Corporation will issue to such person a replacement check or other payment for a like amount upon being furnished with such evidence of non-receipt as it shall reasonably require and upon being indemnified to its satisfaction. Notwithstanding the foregoing, if the Corporation is prevented by circumstances beyond its control (including, without limitation, any interruption in mail service) from making payment of any interest due on this Debenture in the manner provided above, the Corporation may make payment of such interest in any other manner acceptable to the Debentureholder with the same effect as though payment had been made in the manner provided above.

2.5	Regarding Taxes

(a)

The Corporation will be entitled to deduct and withhold any applicable Taxes or similar charges (including interest, penalties or similar amounts in respect thereof) imposed or levied by or on behalf of any government or of any state, province or territory thereof, or any authority or agency therein or thereof, having power to tax, from any payment to be made on or in connection with this Debenture (including, for greater certainty, the issuance of Shares upon any conversion of Debentures and in respect of an Interest Obligation), provided that the Corporation forthwith remits such withheld amount to such government, authority or agency and files all required forms in respect thereof and, at the same time, provides copies of such remittance and filing to the Debentureholder, the amount of any such deduction or withholding will be considered an amount paid in satisfaction of the Corporation’s obligations under this Debenture.

(b)	The Corporation will pay any stamp, issue, registration, documentary or other similar Taxes and other duties (including interest and penalties) payable in respect of the creation, issue, offering, execution or enforcement of this Debenture, or any documentation with respect thereto.

(a)

The Corporation may, at any time and from time to time, purchase this Debenture in the market (which shall include purchase from or through an investment dealer or a firm holding membership on a recognized stock exchange) or by tender offer or by private contract, at any price, subject to compliance with Applicable Securities Laws regarding issuer tender offers.

The Debentureholder of which a part only is purchased, upon surrender of such Debenture for payment, shall be entitled to receive, without expense to such holder, one or more new Debentures for the unpurchased part so surrendered, and the Corporation shall deliver such new Debenture or Debentures upon receipt of the Debenture so surrendered.

ARTICLE 5
CONVERSION OF DEBENTURES

5.1	Applicability

(a)

Subject to applicable regulatory approval (including the approval of such stock exchange(s) on which the Shares are listed, if applicable), this Debenture (subject, however, to any applicable restriction on the conversion of this Debenture contained in Sections 2.1(e), 2.1(m) and/or 5.3(a)) will be convertible into Shares, at such conversion rate or rates, and on such date or dates and in accordance with such other provisions as shall have been determined at the time of issue of this Debenture and shall have been expressed in this Debenture or in an Officer’s Certificate.

(b)

Such right of conversion shall extend only to the maximum number of whole Shares into which the aggregate principal amount of this Debenture surrendered for conversion at any one time by the holder thereof may be converted. Fractional interests in Shares shall be dealt with in the manner provided in Section 5.5.

5.2	Revival of Right to Convert

If this Debenture is called for redemption by the Corporation, but is not redeemed or the payment of the purchase price of this Debenture which has been tendered in acceptance of an offer by the Corporation to purchase this Debenture for cancellation is not made, in the case of a redemption upon due surrender of this Debenture or in the case of a purchase on the date on which such purchase is required to be made, as the case may be, then the right to convert this Debenture shall revive and continue as if this Debenture had not been called for redemption or tendered in acceptance of the Corporation’s offer, respectively.

5.3	Manner of Exercise of Right to Convert

(a)

The holder of this Debenture desiring to convert this Debenture in whole or in part into Shares shall surrender this Debenture to the Corporation at its principal office in Houston, Texas, together with the conversion notice in the form attached as Schedule “B” to this Debenture or any other written notice in a form satisfactory to the Corporation, in either case duly executed by the holder or its executors or administrators or other legal representatives or its or their attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Corporation, exercising its right to convert this Debenture in accordance with the provisions of this Article 5. If the number of Shares issuable upon a conversion of this Debenture would result in the Maximum Conversion Shares being exceeded such that the approval of one or more stock exchange(s) on which the Shares are then listed is required for the Shares issuable upon a conversion this Debenture to be listed on such stock exchange(s), the Corporation shall use its reasonable commercial efforts to obtain the approval of such stock exchange(s) (provided, for greater certainty, such commercially reasonable efforts shall not require the Corporation to seek securityholder approval, if required by such stock exchange(s)) and the conversion shall be conditional on such approval(s) being obtained. Thereupon such Debentureholder or, subject to payment of all applicable stamp or security transfer taxes or other governmental charges and compliance with all reasonable requirements of the Corporation, its nominee(s) or assignee(s), shall be entitled to be entered in the books of the Corporation as at the Date of Conversion (or such later date as is specified Section 5.3(b) or, if stock exchange approval is required in respect of a conversion, as soon as practicable following the date such approval is obtained) as the holder of the number of Shares into which this Debenture is convertible in accordance with the provisions of this Article 5 and, as soon as practicable thereafter, the Corporation shall deliver to such Debentureholder or, subject as aforesaid, its nominee(s) or assignee(s), a certificate or other evidence of such Shares.

(b)

For the purposes of this Article, this Debenture shall be deemed to be surrendered for conversion on the date (herein called the “Date of Conversion”) on which it is so surrendered in accordance with the provisions of this Article 5 and, in if this Debenture is surrendered by post or other means of transmission, on the date on which it is received by Corporation at its principal office in Houston, Texas; provided that if this Debenture is surrendered for conversion on a day on which the register of Shares is closed, the person or persons entitled to receive Shares shall become the holder or holders of record of such Shares as at the date on which such registers are next reopened.

(c)

Any part, being $1,000 or an integral multiple thereof, of this Debenture in a denomination in excess of $1,000 may be converted as provided in this Article and all references in this Debenture to conversion of this Debenture shall be deemed to include conversion of such parts.

(d)

The holder of this Debenture of which only a part is converted shall, upon the exercise of its right of conversion surrender this Debenture to the Corporation, and the Corporation shall cancel the same and shall, if applicable, without charge forthwith deliver to the holder a new Debenture in an aggregate principal amount equal to the unconverted part of the principal amount of this Debenture so surrendered.

(e)

The holder of this Debenture surrendered for conversion in accordance with this Section 5.3 shall be entitled to receive accrued and unpaid interest in accordance with Section 2.1(c) in respect thereof up to but excluding the Date of Conversion of this Debenture and the Shares issued upon such conversion shall rank only in respect of distributions or dividends declared in favour of shareholders of record on and after the Date of Conversion or such later date as such holder shall become the holder of record of such Shares pursuant to Section 5.3, from which applicable date they will for all purposes be and be deemed to be issued and outstanding as fully paid, non-assessable Shares.

5.4	Adjustment of Conversion Price

The Conversion Price in effect at any date shall be subject to adjustment from time to time as set forth below.

(a)

If and whenever at any time prior to the Time of Expiry the Corporation shall (i) subdivide or redivide the outstanding Shares into a greater number of Shares, (ii) reduce, combine or consolidate the outstanding Shares into a smaller number of Shares, or (iii) issue Shares or securities convertible into or exchangeable for Shares to the holders of all or substantially all of the outstanding Shares by way of a dividend or distribution (other than pursuant to any dividend re-investment or Share purchase plans or similar arrangements), the Conversion Price in effect on the effective date of such subdivision, redivision, reduction, combination or consolidation or on the record date for such issue of Shares by way of a dividend or distribution, as the case may be, shall in the case of any of the events referred to in (i) and (iii) above be decreased in proportion to the number of outstanding Shares resulting from such subdivision, redivision, dividend or distribution (including, in the case where securities convertible into or exchangeable for Shares are distributed, the number of Shares that would have been outstanding had all such securities been exchanged for or converted into Shares on such effective date or record date), or shall, in the case of any of the events referred to in (ii) above, be increased in proportion to the number of outstanding Shares resulting from such reduction, combination or consolidation. Such adjustment shall be made successively whenever any event referred to in this 5.4(a) shall occur. Any such issue of Shares by way of a dividend or distribution shall be deemed to have been made on the record date for the dividend or distribution for the purpose of calculating the number of outstanding Shares under Subsections 5.4(b) and 5.4(c) of this Section 5.4.

(b)

If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the issuance of options, rights or warrants, but not including issuances of options, rights or warrants to employees of the Corporation pursuant to an equity incentive plan of the Corporation, to all or substantially all the holders of its outstanding Shares entitling them, for a period expiring not more than 45 days after such record date, to subscribe for or purchase Shares (or securities convertible or exchangeable into Shares) at a price per Share (or having a conversion or exchange price per Share) less than 95% of the Current Market Price of a Share on such record date, the Conversion Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Conversion Price in effect on such record date by a fraction, of which the numerator shall be the total number of Shares outstanding on such record date plus that number of Shares equal to the number arrived at by dividing the aggregate price of the total number of additional Shares offered for subscription or purchase (or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered) by the Current Market Price per Share, and of which the denominator shall be the total number of Shares outstanding on such record date plus the total number of additional Shares offered for subscription or purchase (or into which the convertible or exchangeable securities so offered are convertible). Such adjustment shall be made successively whenever such a record date is fixed. To the extent that any such options, rights or warrants are not so issued or any such options, rights or warrants are not exercised prior to the expiration thereof, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon the number of Shares (or securities convertible or exchangeable into Shares) actually issued upon the exercise of such options, rights or warrants, as the case may be.

(c)

If and whenever at any time prior to the Time of Expiry the Corporation shall fix a record date for the making of a distribution to all or substantially all the holders of its outstanding Shares of (i) shares of any class other than Shares (other than pursuant to any dividend re-investment or share purchase plans or similar arrangements), (ii) rights, options or warrants (excluding rights, options or warrants entitling the holders thereof for a period of not more than 45 days to subscribe for or purchase Shares or securities convertible or exchangeable into Shares), (iii) evidences of its indebtedness, or (iv) other assets (excluding dividends or distributions paid in the ordinary course) then, in each such case, the Conversion Price shall be adjusted immediately after such record date so that it shall equal the price determined by multiplying the Conversion Price in effect on such record date by a fraction, of which the numerator shall be the total number of Shares outstanding on such record date multiplied by the Current Market Price per Share on such record date, less the fair market value (as determined by an investment dealer chosen by the Corporation and subject to applicable exchange or market approval, which determination shall be conclusive) of such shares or rights, options or warrants or evidences of indebtedness or assets so distributed, and of which the denominator shall be the total number of Shares outstanding on such record date multiplied by such Current Market Price per Share. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that such distribution is not so made, the Conversion Price shall be re-adjusted to the Conversion Price which would then be in effect if such record date had not been fixed or to the Conversion Price which would then be in effect based upon such shares or rights, options or warrants or evidences of indebtedness or assets actually distributed, as the case may be.

(d)

Subject to Section 9.1, if and whenever at any time prior to the Time of Expiry, there is a reclassification of the Shares or a capital reorganization of the Corporation other than as described in Section 5.4(a) or a merger or consolidation, of the Corporation with or into any other person, or a sale or conveyance of all or substantially all the assets of the Corporation to any other person, or a liquidation, dissolution or winding up of the Corporation, any holder of a Debenture who has not exercised its right of conversion prior to the effective date of such reclassification, capital reorganization, merger, consolidation, sale or conveyance, or liquidation, dissolution or winding-up, upon the exercise of such right thereafter, shall be entitled to receive and shall accept, in lieu of the number of Shares then sought to be acquired by it, the number of shares or other securities or property of the Corporation or of the person resulting from such merger, amalgamation or consolidation, or to which such sale or conveyance may be made, as the case may be, that such holder of a Debenture would have been entitled to receive on such reclassification, capital reorganization, merger, consolidation, sale or conveyance, or liquidation, dissolution or winding-up, if, on the record date or the effective date thereof, as the case may be, the holder had been the registered holder of the number of Shares sought to be acquired by it and to which it was entitled to acquire upon the exercise of the conversion right.

(e)

In any case in which this Section 5.4 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation shall defer, until the occurrence of such event, issuing to the holder of any Debenture converted after such record date and before the occurrence of such event the additional Shares issuable upon such conversion by reason of the adjustment required by such event before giving effect to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional Shares upon the occurrence of the event requiring such adjustment and the right to receive any dividends or distributions made on such additional Shares declared in favour of holders of record of Shares on and after the Date of Conversion or such later date as such holder would, but for the provisions of this Section 5.4(e), have become the holder of record of such additional Shares pursuant to Section 5.4(b).

(f)

The adjustments provided for in this Section 5.4 are cumulative and shall apply to successive subdivisions, redivisions, reductions, combinations, consolidations, distributions, issues or other events resulting in any adjustment under the provisions of this Section, provided that, notwithstanding any other provision of this Section, no adjustment of the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect; provided however, that any adjustments which by reason of this Section 5.4(f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment

(g)

For the purpose of calculating the number of Shares outstanding, Shares owned by or for the benefit of the Corporation or any Subsidiary of the Corporation shall not be counted.

(h)

If any question or dispute arises with respect to the adjustments provided in this Section 5.4, such question or dispute shall be conclusively determined by a firm of chartered accountants appointed by the Corporation (who may be the Auditors of the Corporation); such accountants shall have access to all necessary records of the Corporation and such determination shall be binding upon the Corporation, and the Debentureholder (subject to manifest error).

(i)

In case the Corporation shall take any action affecting the Shares other than action described in this Section 5.4, which in the opinion of the directors would materially adversely affect the rights of Debentureholders, the Conversion Price shall be adjusted in such manner and at such time as the directors in their sole discretion may determine to be equitable in the circumstances. Failure of the directors to make such an adjustment shall be conclusive evidence that the directors have determined that it is equitable to make no adjustment in the circumstances.

(j)

Subject to the prior written consent of any stock exchange or market upon which the Shares are then listed, as the case may be, and if required, no adjustment in the Conversion Price shall be made in respect of any event described in Section 5.4(a), Section 5.4(b) or Section 5.4(c) if the holders of the Debentures are entitled to participate in such event on the same terms mutatis mutandis as if they had converted their Debentures prior to the effective date or record date, as the case may be, of such event.

(k)

Except as stated above in this Section 5.4, no adjustment will be made in the Conversion Price for any Debentures as a result of the issuance of Shares at less than the Current Market Price for such Shares on the date of issuance.

5.5	No Requirement to Issue Fractional Shares

The Corporation shall not be required to issue fractional Shares upon the conversion of this Debenture pursuant to this Article 5. If more than one Debenture shall be surrendered for conversion at one time by the same holder, the number of whole Shares issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of such Debentures to be converted. If any fractional interest in a Share would, except for the provisions of this Section 5.5, be deliverable upon the conversion of any principal amount of Debentures, the Corporation shall, in lieu of delivering any certificate representing such fractional interest, make a cash payment to the holder of such Debenture of an amount equal to the fractional interest which would have been issuable multiplied by the Current Market Price. Upon request by the Debentureholder, the Corporation shall provide, in writing to the Debentureholder, the price to be paid in respect of such fractional Shares.

5.6	Corporation to Reserve Shares

The Corporation covenants with the Debentureholder that it will at all times reserve and keep available out of its authorized Shares, solely for the purpose of issue upon conversion of this Debenture as in this Article 5 provided, and conditionally allot to the Debentureholder upon the exercise of the conversion rights hereunder, such number of Shares as shall then be issuable upon the conversion of all outstanding Debentures. The Corporation covenants with the Debentureholder that all Shares which shall be so issuable shall be duly authorized and validly issued.

5.7	Cancellation of Converted Debentures

Subject to the provisions of Section 5.3(d) as to the partial conversion of this Debenture, converted in part, if this Debenture is converted in whole or in part under the provisions of this Article 5 it shall be delivered in accordance with Section 5.3(a) to and cancelled by the Corporation and no Debenture shall be issued in substitution therefor.

5.8	Certificate as to Adjustment

The Corporation shall from time to time immediately after the occurrence of any event which requires an adjustment or readjustment as provided in Section 5.4, deliver an Officer’s Certificate to the Debentureholder specifying the nature of the event requiring the same and the amount of the adjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, which certificate and the amount of the adjustment specified therein shall be verified by an opinion of a firm of nationally recognized chartered accountants appointed by the Corporation and acceptable to the Debentureholder (who may be the Auditors of the Corporation) and shall be conclusive and binding on all parties in interest (subject to manifest error). When so approved, the Corporation shall, except in respect of any subdivision, redivision, reduction, combination or consolidation of the Shares, forthwith give notice to the Debentureholder in the manner provided in Section 13.2 specifying the event requiring such adjustment or readjustment and the results thereof, including the resulting Conversion Price; provided that, if the Corporation has given notice otherwise than under this Section 5.8 covering all the relevant facts in respect of such event, no such notice need be given under this Section 5.8.

5.9	Notice of Special Matters

The Corporation covenants with the Debentureholder that so long as this Debenture remains outstanding, it will give notice to the Debentureholder in the manner provided in Section 13.2, of its intention to fix a record date for any event referred to in Section 5.4(a), 5.4(b), or 5.4(c) (other than a subdivision, redivision, reduction, combination or consolidation of its Shares) which may give rise to an adjustment in the Conversion Price, and, in each case, such notice shall specify the particulars of such event and the record date and the effective date for such event; provided that the Corporation shall only be required to specify in such notice such particulars of such event as shall have been fixed and determined on the date on which such notice is given. Such notice shall be given not less than fourteen (14) days, in each case, prior to such applicable record date.

In the event of the Corporation failing, within 30 days after receipt of any such request and such funding of indemnity, to give notice convening a meeting, such Debentureholders, as the case may be, may convene such meeting. Every such meeting shall be held in Houston, Texas.

12.2	Notice of Meetings

At least 21 days’ notice of any meeting shall be given to the Debentureholders in the manner provided in Section 13.2. Such notice shall state the time when and the place where the meeting is to be held and shall state briefly the general nature of the business to be transacted thereat and it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article 12. The accidental omission to give notice of a meeting to any Debentureholder shall not invalidate any resolution passed at any such meeting. A holder may waive notice of a meeting either before or after the meeting.

12.3

Chair

Some person, who need not be a Debentureholder, nominated in writing by the Corporation shall be chair of the meeting and if no person is so nominated, or if the person so nominated is not present within 15 minutes from the time fixed for the holding of the meeting, a majority of the Debentureholders present in person or by proxy shall choose some individual present to be chair.

12.4

Quorum

At any meeting of the Debentureholders a quorum shall consist of Debentureholders present in person or by proxy and representing at least 40% of the principal amount of the outstanding Debentures. If a quorum of the Debentureholders shall not be present within 30 minutes from the time fixed for holding any meeting, the meeting, if summoned by the Debentureholders or pursuant to a request of the Debentureholders, shall be dissolved, but in any other case the meeting shall be adjourned to the same day in the next week (unless such day is not a Business Day in which case it shall be adjourned to the next following Business Day thereafter) at the same time and place, to the extent possible, and no notice shall be required to be given in respect of such adjourned meeting. At the adjourned meeting, the Debentureholders present in person or by proxy shall constitute a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not represent 40% of the principal amount of the outstanding Debentures. Any business may be brought before or dealt with at an adjourned meeting which might have been brought before or dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless the required quorum is present at the commencement of business.

In the case of joint holders of a Debenture, any one of them present in person or by proxy at the meeting may vote in the absence of the other or others but in case more than one of them is present in person or by proxy, they shall vote together in respect of the Debentures of which they are joint holders.

12.8

Proxies

A Debentureholder may be present and vote at any meeting of Debentureholders by an authorized representative. The Corporation, for the purpose of enabling the Debentureholders to be present and vote at any meeting without producing their Debentures, and of enabling them to be present and vote at any such meeting by proxy and of lodging instruments appointing such proxies at some place other than the place where the meeting is to be held, may from time to time make and vary such regulations as it shall think fit providing for and governing any or all of the following matters:

(b)

the deposit of instruments appointing proxies at such place as the Corporation or the Debentureholder convening the meeting, as the case may be, may, in the notice convening the meeting, direct and the time, if any, before the holding of the meeting or any adjournment thereof by which the same must be deposited; and

(c)

the deposit of instruments appointing proxies at some approved place or places other than the place at which the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed, faxed or sent by other electronic means before the meeting to the Corporation at the place where the same is to be held and for the voting of proxies so deposited as though the instruments themselves were produced at the meeting.

Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. The Corporation may dispense with any such deposit and permit Debentureholders to make proof of ownership in such other manner as the Corporation may approve. Save as such regulations may provide, the only persons who shall be recognized at any meeting as the holders of any Debentures, or as entitled to vote or be present at the meeting in respect thereof, shall be Debentureholders and persons whom Debentureholders have by instrument in writing duly appointed as their proxies.

12.9	Persons Entitled to Attend Meetings

The Corporation, by its officers, employees, and directors, the Auditors of the Corporation and the legal advisers of the Corporation, or any Debentureholder may attend any meeting of the Debentureholders, but shall have no vote as such.

12.10

Powers Cumulative

Any one or more of the powers in this Debenture stated to be exercisable by the Debentureholders may be exercised from time to time and the exercise of any one or more of such powers from time to time shall not be deemed to exhaust the rights of the Debentureholders to exercise the same or any other such power or powers thereafter from time to time.

12.12

Instruments in Writing

All actions which may be taken and all powers that may be exercised by the Debentureholders as provided in this Debenture may be taken and exercised at a meeting of holders held as hereinbefore in this Article 12 provided or by the requisite amount of such holders as set forth in Article 11 or otherwise provided herein pursuant to an instrument in writing signed in one or more counterparts, and the expression “resolution” or “Ordinary Resolution” when used in this Debenture shall include an instrument so signed.

12.14

Evidence of Rights of Debentureholders
