In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing.

appointed in writing, at any meeting of Debentureholders duly called and held in accordance with the provisions of Article 13, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such requisite instrument or instruments are delivered to the Indenture Trustee and, where it is hereby expressly required, to the Corporation. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act of Holders” or the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and, subject to section 12.1, conclusive in favour of the Indenture Trustee and the Corporation, if made in the manner provided in this section 1.12.

(b)

For the purposes of the Interest Act (Canada), if in this Indenture or in any Debenture a rate of interest is or is to be calculated on the basis of a period which is less than a full calendar year, the yearly rate of interest to which such rate is equivalent is such rate multiplied by the actual number of days in the calendar year for which such calculation is made and divided by 360 days.

(c)

The rate of interest stipulated in this Indenture or in any Debenture will be calculated using the nominal rate method of calculation, and will not be calculated using the effective rate method of calculation or on any other basis that gives effect to the principle of deemed re-investment of interest.

(d)

In calculating interest under this Indenture or under a Debenture for any period, unless otherwise specifically stated, the first day of such period shall be included and the last day of such period shall be excluded.

(a)

The Debentures shall be dated as of the Issue Date. The Debentures shall bear interest from and including the Issue Date at the rate of 6.25% per annum (after as well as before Maturity, default and judgment, with interest on overdue interest at the said rate), payable in equal semi-annual instalments in arrears on each Interest Payment Date subject to section 2.3, and the Debentures shall mature on the Maturity Date (unless redeemed or repurchased in accordance with this Indenture).

The Debentures shall be issued as fully registered Debentures in denominations of $1,000 and integral multiples of $1,000 or as a Global Debenture, shall be redeemable as provided for in Article 3 and shall be convertible as provided for in Article 4.

The Debentures and the certificate of the Indenture Trustee endorsed thereon shall be substantially in the form set forth in Schedule “A” hereto, provided that if a Debenture is issued as a Global Debenture in accordance with section 2.11, it shall have appended thereto a principal amount grid in the form of Schedule “A” to the form of Debenture attached as Schedule “A” hereto which shall be appropriately adjusted at such times as Debentures are converted, redeemed or repurchased in accordance with the terms hereof.

The forwarding of such funds by the Corporation to the Indenture Trustee shall satisfy and discharge the Corporation’s liability for payment of the interest on the Debentures to the extent of the sums represented thereby, plus the amount of any withholding or other tax deducted as aforesaid, unless such cheque is not paid at par on presentation; provided that in the event of the non-receipt of such cheque by the Holder, or the loss or destruction thereof, the Indenture Trustee on being furnished with reasonable evidence of such non-receipt, loss or destruction and indemnity reasonably satisfactory to it shall issue to such Holder a replacement cheque for the amount of such cheque. 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 each Debenture in the manner provided above, the Corporation may make payment of such interest or make such interest available for payment in any other manner acceptable to the Indenture Trustee with the same effect as though payment had been made in the manner provided above.
	(b)		If a Debenture or a portion thereof is called or presented for redemption, repurchase or conversion and the Redemption Date, Payment Date or Conversion Date is subsequent to a Regular Interest Record Date but prior to the related Interest Payment Date, interest accrued on such Debenture will be paid upon presentation and surrender of such Debenture to the Corporate Trust Office up to but excluding the Redemption Date, the Payment Date or the Conversion Date.
	(c)		Subject to the foregoing provisions of this section, each Debenture delivered upon the transfer of or in exchange for or in lieu of any other Debenture shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Debenture.

2.11 Book-Based System

	(a)		The Debentures shall be issued as Book-Entry Only Debentures and shall be represented by one or more fully-registered permanent global security certificates in the form of the certificate set out in Schedule “A” hereto together with the legend provided for in section 2.11(b) (the “Global Debenture(s)”). The Global Debenture(s) shall be held by, or on behalf of, the Depository as depository of the Participants in the Book-Based System and shall be registered in the name of “CDS & Co.” (or such other name as the Depository may use from time to time as its nominee for the purposes of the Book-Based System). No Beneficial Holder will receive Definitive Debentures representing their beneficial ownership in Debentures unless the Corporation determines to terminate the Book-Entry Only Debentures.
	(b)		The Global Debenture(s) shall bear a legend in substantially the following form subject to modification as required by the Depository:
			“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO STUDENT TRANSPORTATION INC. (THE “ISSUER”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO., OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED HOLDER HEREOF, CDS & CO., HAS A PROPERTY INTEREST IN THE SECURITIES REPRESENTED BY THIS CERTIFICATE HEREIN AND IT IS A VIOLATION OF ITS RIGHTS FOR ANOTHER PERSON TO HOLD, TRANSFER OR DEAL WITH THIS CERTIFICATE”

2.12 Payments of Principal and Interest for Book-Entry Only Debentures

Subject to section 3.7(d), section 3.9 and Article 5, as payments in respect of principal and interest on the Debentures represented by the Global Debenture(s) become due, the Corporation shall (except in cases of payments on Maturity, redemption, repurchase or conversion which shall be made only upon presentation and surrender of the Global Debenture(s)), no later than on the applicable Interest Payment Date or on the Maturity Date, as the case may be, at the option of the Corporation:

	(a)		deliver or cause to be delivered to the office of the Indenture Trustee at the Corporate Trust Office at or before 10:00 a.m. three Business Days before such Interest Payment Date or Maturity Date, a certified cheque for the amount of such payment payable on such Interest Payment Date or Maturity Date, as the case may be, to the order of the Indenture Trustee and negotiable at par, or
	(b)		provide to the Indenture Trustee such payment by electronic funds transfer to an account designated by the Indenture Trustee, at or before 10:00 a.m. on the Business Day preceding such Interest Payment Date or Maturity Date, as the case may be,

for all amounts due in respect of such principal and interest on the Debentures represented by the Global Debenture(s) to enable the Indenture Trustee to forward or cause to be forwarded such funds to the Depository for credit by the Depository to Participants’ accounts. Neither the Corporation nor the Indenture Trustee for any Debenture issued as a Global Debenture will be liable or responsible to any Person for any aspect of the records related to or payments made on account of beneficial interests in any Global Debenture as for maintaining, reviewing or supervising any records relating to such beneficial interests.

2.13 Rank and Subordination

The Debentures certified and issued under this Indenture rank pari passu with one another, in accordance with their tenor without discrimination, preference or priority and with all other present and future subordinated and unsecured Indebtedness of the Corporation. The payment of the principal of and interest on the Debentures is expressly subordinated in right of payment to the prior payment in full of Senior Indebtedness, as provided in Article 8.

2.14 Register and Transfer

	(a)		The Corporation shall cause to be kept by and at the principal office of the Indenture Trustee in the City of Toronto, Province of Ontario, a register, and in such other place or places by the Indenture Trustee, if any, as the Corporation with the approval of the Indenture Trustee may designate, branch registers, in which shall be entered the names and latest known addresses of the Debentureholders and the other particulars prescribed by law of the Debentures held by them respectively and all transfers of Debentures. Such registration shall be noted on the Debentures by the Indenture Trustee. No transfer of a Debenture shall be effective as against the Corporation unless made on one of the appropriate registers by the registered Holder or his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Indenture Trustee, upon compliance with such requirements as the Indenture Trustee may prescribe, and unless such transfer shall have been duly noted on such Debenture by the Indenture Trustee.
	(b)		With respect to Debentures issued as Book-Entry Only Debentures, the Corporation shall cause to be kept by and at the principal office of the Indenture Trustee in the City of

Toronto, Province of Ontario, a central register in which shall be entered the name(s) and latest known address(es) of the Holder(s) of each Global Debenture (being the Depository, or its nominee, for such Global Debenture) and the other particulars prescribed by law of the Debentures held by it (them) and all transfers of Debentures. Notwithstanding any other provision of this Indenture, a Global Debenture may not be transferred by the registered holder thereof except through records maintained by CDS or its nominee in the following circumstances or as otherwise specified in a Board Resolution or Written Order:

	(A)		the Global Debenture may be transferred by a Depository to a nominee of such Depository or by a nominee of a Depository to such Depository or to another nominee of such Depository or by a Depository or its nominee to a successor Depository or its nominee;
	(B)		the Global Debenture may be transferred at any time after the Depository for such Global Debenture (1) has notified the Corporation that it is unwilling or unable to continue as Depository for such Global Debenture or (2) ceases to be eligible to be a Depository provided that at the time of such transfer the Corporation has not appointed a successor Depository for such Global Debenture;
	(C)		the Global Debenture may be transferred at any time after the Corporation has determined, in its sole discretion, to terminate the Book-Based System in respect of such Global Debenture and has communicated such determination to the Indenture Trustee in writing; and
	(D)		the Global Debenture may be transferred at any time after the Indenture Trustee has determined that an Event of Default has occurred and is continuing with respect to the Debentures issued as a Global Debenture, provided that at the time of such transfer the Indenture Trustee has not waived the Event of Default pursuant to Article 10.

2.15 Additional Amount

(a)

Any payments made by or on behalf of the Corporation under or with respect to the Debentures will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge imposed or levied by or on behalf of the Government of Canada or of any province or territory of Canada or by any authority or agency thereof or therein having power to tax (collectively, “Taxes”), unless the Corporation or any other payor is required to withhold or deduct Taxes by Applicable Law or by the interpretation or administration thereof by the relevant Governmental Authority. If the Corporation is so required to withhold or deduct any amount for or on account of Taxes from any payment made to a Holder under or with respect to the Debentures, the Indenture Trustee will make such withholding or deduction and will remit the full amount withheld or deducted to the relevant Governmental Authority as and when required by Applicable Law and the Corporation will pay to the Indenture Trustee such additional amounts (the “Additional Amounts”) as may be necessary so that the net amount received (including Additional Amounts) by each Holder (other than an Excluded Holder) after such withholding or deduction (including any withholding or deduction required to be made in respect of any Additional Amounts) will not be less than the amount such Holder would have received if

			such Taxes had not been withheld or deducted; provided, however, that no Additional Amounts will be payable with respect to any payment to a Holder (an “Excluded Holder”) in respect of a Beneficial Holder who is liable for such Taxes in respect of such Debentures (i) by reason of such Holder or Beneficial Holder being a Person with whom the Corporation is not dealing at arm’s length for the purposes of the Income Tax Act (Canada) at the time of making such payment, (ii) by reason of the existence of any present or former connection between such Holder or Beneficial Holder and Canada or any province or territory thereof other than solely by reason of the Holder’s activity in connection with purchasing the Debentures, the mere holding, deemed holding, use or ownership of the Debentures, or receiving payments under or enforcing any rights in respect of such Debentures as a non-resident or deemed non-resident of Canada or any province or territory thereof, or (iii) by reason of its failure to comply with any certification, identification, information, documentation or other reporting requirement if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to the exemption from, or a reduction in the rate of deduction or withholding of, such Taxes.
	(b)		Within 90 days after the date the payment of any Taxes is due pursuant to Applicable Law, the Indenture Trustee will furnish to the Corporation copies of tax receipts evidencing such payment by the Indenture Trustee.
	(c)		At least 30 days prior to each date on which any payment under or with respect to the Debentures is due and payable, if the Corporation to its knowledge will be obligated to pay Additional Amounts with respect to such payment, the Corporation will deliver to the Indenture Trustee an Officer’s Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Indenture Trustee to pay such Additional Amounts to Holders on the date payment is due.
	(d)		Whenever in the Indenture or in any Debenture there is mentioned, in any context, the payment of principal (and premium, if any), Redemption Amount, a purchase price pursuant to an Offer to Purchase, interest or any other amount payable under or with respect to any Debenture, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.
	(e)		The Corporation will indemnify and hold harmless each Holder (other than an Excluded Holder) and upon written request reimburse each of the Holders for the amount of any Taxes in respect of which any Additional Amounts are payable but not paid by the Corporation including Taxes levied or imposed on the Holder with respect to any indemnity payment, but excluding (i) any Taxes on such Holder’s net income or capital, and (ii) any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or governmental charge.

2.16 Cancellation of Debentures

(a)

All Debentures surrendered for payment of the final amount required to be paid thereon or that have been redeemed as contemplated by Article 3, or that have been surrendered to the Indenture Trustee for registration of exchange or transfer, shall be promptly cancelled by the Indenture Trustee on receipt. The Indenture Trustee shall give prompt written notice to the Corporation of the particulars of any Debentures cancelled by it.

	(b)		The Corporation may, in its discretion at any time, deliver to the Indenture Trustee for cancellation any Debentures which the Corporation has purchased as provided for in this Indenture, and all such Debentures so delivered shall be cancelled by the Indenture Trustee.
	(c)		All Debentures which have been cancelled by the Indenture Trustee shall be destroyed by the Indenture Trustee in accordance with its standard practices, and the Indenture Trustee shall furnish to the Corporation a destruction certificate setting forth the numbers and denominations of the Debentures so destroyed.

2.17 Mutilated, Lost, Stolen or Destroyed Debentures

	(a)		If any Debenture has been mutilated or defaced or has or has been alleged to have been lost, stolen or destroyed, then, on application by the applicable Holder to the Indenture Trustee, the Corporation may, in its discretion, execute, and upon such execution the Indenture Trustee shall certify and deliver, a new Debenture of the same date and amount as the defaced, mutilated, lost, stolen or destroyed Debenture in exchange for and in place of the defaced or mutilated Debenture, and in lieu of and in substitution for the lost, stolen or destroyed Debenture. Notwithstanding the foregoing, no Debenture shall be delivered as a replacement for any Debenture which has been mutilated or defaced otherwise than upon surrender of the mutilated or defaced Debenture, and no Debenture shall be delivered as a replacement for any Debenture which has been lost, stolen or destroyed unless the applicant for the replacement Debenture has furnished to the Corporation and the Indenture Trustee evidence, satisfactory in form and substance to the Corporation and the Indenture Trustee, of its ownership of, and of such loss, theft or destruction of, such Debenture and has provided such a surety bond and indemnity to the Corporation and the Indenture Trustee in amount, form and substance satisfactory to each of them. Any instructions by the Corporation to the Indenture Trustee under this section shall include such indemnity for the protection of the Indenture Trustee as the Indenture Trustee may reasonably require.
	(b)		If any mutilated, defaced, lost, stolen or destroyed Debenture has become or is about to become due and payable, the Corporation, in its discretion, may, instead of executing a replacement Debenture, pay to the Holder thereof the full amount outstanding on such mutilated, defaced, lost, stolen or destroyed Debenture.
	(c)		Upon the issuance of a replacement Debenture, the Corporation may require the applicant for such replacement Debenture to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in relation to such issuance and any other expenses (including the fees and expenses of the Indenture Trustee and the Corporation) connected with such issuance.
	(d)		Each replacement Debenture shall bear a unique serial number and be in a form otherwise identical to the Debenture it replaces and shall be entitled to the benefits of this Indenture to the same extent and in the same manner as the Debenture it replaces.
	(e)		Unless the Corporation instructs otherwise, the Indenture Trustee shall, in accordance with its practice, destroy each mutilated or defaced Debenture surrendered to and cancelled by it and in respect of which a replacement Debenture has been delivered or moneys have been paid and shall, as soon as reasonably practicable, furnish to the Corporation a certificate as to such destruction specifying in numerical sequence the serial numbers of the Debentures so destroyed.

2.18 Access to Lists of Holders

	(a)		The register of Debentureholders maintained by the Indenture Trustee will, during the regular business hours of the Indenture Trustee be open for inspection by the Corporation.
	(b)		If any Beneficial Holder or group of Beneficial Holders, or such one or more Holders as may be permitted by Applicable Law (in each case, the “Applicants”) apply to the Indenture Trustee (with a copy to the Corporation), then the Indenture Trustee, after having been funded and indemnified to its reasonable satisfaction by such Applicants for its related costs and expenses, shall afford or shall cause the Corporation to afford the Applicants access during normal business hours to the most recent list of Debentureholders within 10 Business Days after the receipt of such application by the Indenture Trustee. Such list shall be as of a date no more than 10 days (or such other date as may be mandated by Applicable Law) prior to the date of receipt of the Applicants’ request.

	(a)		The Debentures are not redeemable on or prior to June 30, 2014. The Corporation shall have the right at its option to redeem the Debentures, in whole at any time or in part from time to time, on or after July 1, 2014 and prior to June 30, 2016, on not more than 60 days and not less than 30 days prior notice to the Holders, at a redemption price equal to the principal amount of the Debentures to be redeemed, plus accrued and unpaid interest thereon, if any, up to but excluding the Redemption Date (the “Redemption Amount”), provided that the Weighted Average Trading Price of the Common Shares on a Recognized Stock Exchange for the 20 consecutive Trading Days ending five Trading Days prior to the date on which the Redemption Notice is given (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the date on which the Redemption Notice is given) is not less than 125% of the Conversion Price.
	(b)		On or after June 30, 2016 and prior to the Maturity Date, the Corporation shall have the right at its option to redeem the Debentures, in whole at any time or in part from time to time, on not more than 60 days and not less than 30 days prior notice to the Holders, at the Redemption Amount.
	(c)		Concurrently with providing the Redemption Notice, the Corporation shall provide the Indenture Trustee with an Officer’s Certificate setting forth the details of any redemption contemplated by this section 3.1 (including the Current Market Price, the eligibility and interest calculations, if necessary) which the Indenture Trustee may rely upon without any independent obligation to verify the accuracy of information set out therein.

3.2 Partial Redemption of Debentures

(a)

If less than all the Outstanding Debentures are to be redeemed pursuant to section 3.1, the Corporation shall, in each such case, at least 15 days before the date upon which the Redemption Notice is to be given, notify the Indenture Trustee by a Written Order of its intention to redeem such Debentures and of the aggregate principal amount of Debentures

			to be redeemed. At any time prior to the date upon which the Redemption Notice is to be given, the Corporation may revoke such Written Order by delivering a second Written Order to the Indenture Trustee stating that the Corporation no longer intends to make a partial redemption of the Debentures.
	(b)		The Debentures to be so redeemed shall:

	(i)		in the case of Book-Entry Only Debentures, be redeemed on a pro rata basis to the nearest multiple of $1,000 in accordance with the principal amount of the Outstanding Debentures; or
	(ii)		in the case of Definitive Debentures, be selected by the Indenture Trustee (i) on a pro rata basis to the nearest multiple of $1,000 in accordance with the principal amount of the Debentures registered in the name of each Holder, (ii) by lot in such manner as the Indenture Trustee may deem equitable, or (iii) in such other manner as the Indenture Trustee may deem equitable.

(c)

Debentures in denominations in excess of $1,000 may be selected and called for redemption in part only (such part being $1,000 or an integral multiple thereof) and, unless the context otherwise requires, references to Debentures in this Article 3 shall be deemed to include any such part of the principal amount of Debentures which shall have been so selected and called for redemption. The Holder of any Debenture called for redemption in part only, upon surrender of such Debenture for payment, shall be entitled to receive, without expense to such Holder, a replacement Debenture for and evidencing the same obligation as the unredeemed part of the Debenture so surrendered, and the Indenture Trustee shall certify and deliver such replacement Debenture upon receipt of the Debenture so surrendered.

Every such notice shall specify the aggregate principal amount of Debentures called for redemption, the Redemption Amount relating thereto, the Redemption Date, the places of payment and any right of the Holders to convert such Debentures as provided in Article 4 and shall state that interest upon the principal amount of Debentures called for redemption shall cease to be payable from and after the Redemption Date.

3.5 Debentures Due on Redemption Date

Upon a Redemption Notice being given in accordance with section 3.4, the Redemption Amount shall be and become due and payable on the Redemption Date specified in such Redemption Notice and with the same effect as if it were the Maturity Date of such Debentures, the provisions hereof or of any such Debentures notwithstanding, and, from and after such Redemption Date, interest shall cease to accrue, unless payment of the Redemption Amount shall not be made on presentation for surrender of such Debentures at any of the places specified in section 3.4 on or after the Redemption Date.

3.6 Deposit of Redemption Moneys

Upon the Debentures being called for redemption as provided for in section 3.4, but subject to section 3.7, the Corporation shall deposit with the Indenture Trustee or for the account of the Indenture Trustee, one Business Day prior to the Redemption Date specified in the Redemption Notice, such sums as are sufficient to pay the Redemption Amount of the Debentures. From the sums so deposited, the Indenture Trustee shall pay or cause to be paid to the Holders, upon surrender of the Debentures, the Redemption Amount thereof.

3.7 Right to Repay the Redemption Amount in Common Shares on Redemption

	(a)		Provided that the Corporation is entitled to redeem the Debentures pursuant to section 3.1 and that no Event of Default shall have occurred and be continuing, the Corporation, subject to receiving all applicable regulatory approvals, shall have the right, in respect of a Redemption Date, to elect to satisfy its obligation to pay the Redemption Amount by issuing and delivering to Holders on the Redemption Date, for each $1,000 principal amount of Debentures, that number of fully paid and non-assessable Freely Tradeable Common Shares obtained by dividing such principal amount by 95% of the Current Market Price of the Common Shares on the Redemption Date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the Redemption Date) (the “Share Redemption Right”).
	(b)		The Corporation shall exercise the Share Redemption Right by so specifying in the Redemption Notice not less than 40 days and not more than 60 days prior to the Redemption Date.
	(c)		The Corporation’s right to exercise the Share Redemption Right shall be conditional upon the following conditions being met on the Business Day preceding the Redemption Date:

	(ii)		the listing or quoting of such additional Common Shares on each Recognized Stock Exchange on which the Common Share are then listed;
	(iii)		the Corporation being a reporting issuer or equivalent in good standing or equivalent under Applicable Securities Laws in the provinces and territories of Canada in which the Corporation is a reporting issuer;
	(iv)		no Event of Default shall have occurred and be continuing;
	(v)		the receipt by the Indenture Trustee of an Officer’s Certificate stating that conditions (i), (ii), (iii) and (iv) above have been satisfied and setting forth the number of Common Shares to be delivered for each $1,000 principal amount of Debentures and the Current Market Price of the Common Shares on the Redemption Date; and
	(vi)		the receipt by the Indenture Trustee of an Opinion of Counsel to the effect that such Common Shares have been duly authorized and, when issued and delivered

pursuant to the terms of this Indenture in payment of the Redemption Amount of the Debentures outstanding, will be validly issued as fully paid and non-assessable, that conditions (i) and (ii) above have been satisfied and that, relying exclusively on certificates of good standing or no default issued by the relevant securities regulatory authorities, condition (iii) above is satisfied, except that the opinion in respect of condition (iii) need not be expressed with respect to those provinces and territories where such certificates are not issued.

			If the foregoing conditions are not satisfied prior to the close of business on the Business Day preceding the Redemption Date, the Corporation shall pay in cash the Redemption Amount that would otherwise have been satisfied in Common Shares, unless such Debentureholder waives the conditions which are not satisfied or extends the time by which the Corporation is to satisfy such conditions.
	(d)		In the event that the Corporation exercises its Share Redemption Right, the Corporation shall, on the Redemption Date, deliver or cause to be delivered to the Indenture Trustee, for delivery to and on account of the Holders, certificates representing the Freely Tradeable Common Shares to which such Holders are entitled and a cheque representing accrued and unpaid interest. Upon presentation and surrender of the Debentures by a Holder at the Corporate Trust Office or any other place specified in the Redemption Notice, the Indenture Trustee shall deliver the certificates representing such Common Shares and any such interest payment to the Holder.
	(e)		No fractional Common Shares shall be delivered upon the exercise of the Share Redemption Right but, in lieu thereof, if such a fraction shall become owing, the Corporation shall pay to the Indenture Trustee for the account of the Holders, at the time contemplated in section 3.7(d), the cash equivalent thereof determined on the basis of the Current Market Price of the Common Shares on the Redemption Date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the Redemption Date).
	(f)		A Holder shall be treated as the shareholder of record of the Common Shares issued on due exercise by the Corporation of its Share Redemption Right effective immediately after the close of business on the Redemption Date, and shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including stock dividends and dividends or distributions in kind) thereon and arising thereafter, and in the event that the Indenture Trustee receives the same, it shall hold the same under gratuitous deposit for the benefit of such Holder.
	(g)		The Corporation shall at all times reserve and keep available out of its authorized Common Shares (if the number thereof becomes limited) solely for the purpose of issue and delivery upon the exercise of the Share Redemption Right as provided herein, and shall issue to Debentureholders to whom Common Shares will be issued pursuant to the exercise of the Share Redemption Right, such number of Common Shares as shall be issuable in such event.
	(h)		The Corporation shall comply with all Applicable Securities Laws regulating the issue and delivery of Freely Tradeable Common Shares upon exercise of the Share Redemption Right, shall obtain any regulatory approval in respect thereof as may be required pursuant to Applicable Securities Laws and shall cause to be listed and posted for trading such Common Shares on each Recognized Stock Exchange.

(i)

If the Corporation elects to satisfy its obligation to pay the Redemption Amount by issuing Common Shares in accordance with this section 3.7 and if the Redemption Amount (or any portion thereof) to which a Holder is entitled is subject to withholding Taxes, the Corporation shall satisfy the payment of such withholding Taxes pursuant to section 2.15.

3.8 Purchase of Debentures

	(a)		Provided that no Event of Default has occurred and is continuing, the Corporation may purchase all or any of the Debentures in the open market (which shall include purchase from or through an investment dealer or a firm holding membership on a Recognized Stock Exchange) or by tender or by private contract at any price, subject to compliance with Applicable Securities Laws. If an Event of Default has occurred and is continuing, the Corporation may purchase all or any of the Debentures as aforesaid with the exception of by private contract.
	(b)		If, upon an invitation for tenders, more Debentures are tendered at the same lowest price than the Corporation is prepared to accept, the Debentures to be purchased by the Corporation will be selected by the Indenture Trustee on a pro rata basis or in such other manner consented to by the TSX (or any other stock exchange on which the Debentures may be listed, if any) which the Indenture Trustee considers appropriate, from the Debentures tendered by each tendering Debentureholder who tendered at such lowest price. The Holder of any Debenture of which a part only is purchased, upon surrender of such Debenture for payment, shall be entitled to receive, without expense to such Holder, a replacement Debenture for and evidencing the same obligation as the unpurchased part of the Debenture so surrendered and the Indenture Trustee shall certify and deliver such replacement Debenture upon receipt of the Debenture so surrendered. The Depository shall make notations on the Global Debenture of the principal amount so purchased.

3.9 Repurchase of Debentures upon a Change of Control

(a)

Within 30 days of the occurrence of a Change of Control, the Corporation shall be obligated to offer to purchase all the Debentures then Outstanding. The terms and condition of such obligation are set forth as follows:

The Indenture Trustee will promptly thereafter deliver the Offer to Purchase to the Holders of all Debentures then Outstanding at their addresses appearing in the registers of Holders maintained by the Indenture Trustee.
	(ii)		The Offer to Purchase shall specify:

(A)

the Offer Price for the Debentures;

	(C)		that the Offer to Purchase may be accepted by the Debentureholders by tendering the Debentures so held by them to the Indenture Trustee at the Corporate Trust Office or such other address specified in the notice prior to the Expiry Time together with the acceptance notice (the “Acceptance Notice”) in form and substance acceptable to the Corporation and the Indenture Trustee;
	(D)		that Debentureholders may accept the Offer to Purchase in respect of all or a portion (in a minimum amount of $1,000 principal amount and multiples thereof) of their Debentures;
	(E)		a date (the “Payment Date”) no later than the third Business Day following the Expiry Date on which the Corporation shall take up and pay for all the Debentures duly tendered in acceptance of the Offer to Purchase; and
	(F)		that Holders will be entitled to withdraw their election if the Indenture Trustee receives, not later than the Expiry Time, a facsimile transmission or letter setting forth the name of such Holder, the principal amount of Debentures delivered for purchase and a statement that such Holder is withdrawing his election to have such Debentures purchased.

			If any of the Debentures are in the form of Global Debentures, then the Corporation shall modify such notice to the extent necessary to accord with the applicable procedures at the Book-Based System relating to the purchase of the Book-Entry Only Debentures.
	(iii)		The Corporation shall deposit with the Indenture Trustee one Business Day prior to the Payment Date, an amount of money sufficient to pay the aggregate Offer Price in respect of all Debentures duly tendered to the Offer to Purchase (less any Taxes required to be withheld or deducted in accordance with Applicable Law). On the Payment Date, the Corporation shall (A) accept for payment Debentures or portions thereof duly tendered pursuant to the Offer to Purchase, and (B) deliver, or cause to be delivered, to the Indenture Trustee an officer’s certificate specifying the Debentures or portions thereof accepted for payment by the Corporation. The Indenture Trustee will pay the Offer Price to the Holders of the Debentures in the respective amounts to which they are entitled in accordance with the Offer to Purchase as aforesaid.

(b)

If holders of 90% or more of the aggregate principal amount of Debentures Outstanding on the date the Corporation delivers the Offer to Purchase to the Trustee accept the Offer to Purchase, the Corporation shall have the right (the “90% Redemption Right”), upon written notice (the “90% Redemption Right Notice”) provided to the Trustee within 10 days following the Payment Date, to elect to redeem all the Debentures remaining Outstanding at the Offer Price and on the other terms and conditions provided herein.

Upon receipt of such notice by the Indenture Trustee, the Indenture Trustee shall promptly provide written notice to each Holder of Debentures then Outstanding (other than those that have accepted the Offer to Purchase) that:

	(i)		the Corporation has exercised the 90% Redemption Right and is purchasing all Outstanding Debentures effective as at the Payment Date at the Offer Price;
	(ii)		such Holder must surrender its Debentures to the Indenture Trustee within 10 days after the sending of such notice; and
	(iii)		the rights of such Holder under the terms of the Debentures and this Indenture shall cease effective as of the Payment Date provided the Corporation has, on or before the date on which the Corporation delivers the 90% Redemption Notice to the Indenture Trustee, paid the aggregate Offer Price to, or to the order of, the Indenture Trustee and thereafter such Holder’s Debentures shall not be considered to be Outstanding and such Holder shall not have any rights hereunder except to receive such Offer Price to which such Holder is entitled upon surrender and delivery of such Holder’s Debentures in accordance with the Indenture.

			The Corporation shall, on the Business Day immediately prior to the date the Corporation delivers the 90% Redemption Right Notice, pay to the Indenture Trustee by wire transfer or such other means as may be acceptable to the Indenture Trustee, an amount of money sufficient to pay the aggregate Offer Price in respect of all Debentures to be redeemed pursuant to the 90% Redemption Right (less any Taxes required to be withheld or deducted in accordance with Applicable Law). The Indenture Trustee, on behalf of the Corporation, will pay the Offer Price to the Holders of Debentures in the respective amounts to which they are entitled in accordance with the exercise of the 90% Redemption Right as aforesaid upon surrender and delivery of such Holders’ Debentures.
	(c)		The Debentures in respect of which the Corporation has made payment to the Indenture Trustee in accordance with the terms of sections 3.9(a) and 3.9(b) (or the portion thereof tendered in acceptance of the Offer to Purchase) shall thereafter no longer be considered to be Outstanding under this Indenture. The Corporation shall also deposit with the Indenture Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Indenture Trustee in connection with the Offer to Purchase and the exercise of the 90% Redemption Right if applicable. All Debentures in respect of which payment of the Offer Price has been so made shall be cancelled by the Indenture Trustee.
	(d)		In the event only a portion of the principal amount of a Debenture is tendered by a Holder thereof in acceptance of the Offer to Purchase, the Corporation shall execute and deliver to the Indenture Trustee and the Indenture Trustee shall certify and deliver to the Holder, without charge to such holder, a certificate representing the principal amount of the Debenture not so tendered in acceptance of the Debenture Offer.
	(e)		The following provisions shall apply in respect of the occurrence of a Cash Change of Control:

(i)

In the event of the occurrence of a Cash Change of Control, for purposes of the conversion of Debentures pursuant to this Indenture, the Conversion Price in effect during the period (the “Cash Change of Control Conversion Period”) beginning on the 10th day prior to the effective date of the Change of Control (the

			“Effective Date”) and ending at the close of business on the 30th day after the date on which the Offer to Purchase in respect of the Cash Change of Control is delivered or mailed to the Indenture Trustee in accordance with section 3.9 (the “Cash Change of Control Conversion Price”) shall be calculated in accordance with the following formula:
			CCOCCP = OCP/(1+(CP x (c/t))) where:
			CCOCCP is the Cash Change of Control Conversion Price;
			OCP = is the Conversion Price in effect on the Effective Date;
			CP = 39.4%;
			c = the number of days from and including the Effective Date to but excluding the Maturity Date; and
			t = the number of days from and including the date hereof to but excluding the Maturity Date.
			In the event that the Cash Change of Control Conversion Price calculated in accordance with the formula above is less than any regulatory permitted discount to market price, the Cash Change of Control Conversion Price shall be deemed to be that implied by the maximum permitted discount to market price.
	(ii)		Notwithstanding the foregoing, if the Conversion Date of any Debentures occurs during the period beginning on the 10th day prior to the Effective Date and ending at the close of business on the Effective Date, the Holders of such Debentures shall, on conversion of their Debentures, only be entitled to that number of Common Shares resulting from the Cash Change of Control Conversion Price in excess of the number of Common Shares to which they would otherwise have been entitled to (the “Base Shares”) at the Conversion Price that would then have been in effect but for the Cash Change of Control (such excess number of Common Shares being the “Make Whole Premium Shares”) on the Business Day immediately following the Effective Date and, for greater certainty, only if the Change of Control occurs. The Base Shares shall be issued in accordance with the terms of this Indenture applicable to a conversion of Debentures otherwise than during the Cash Change of Control Conversion Period, including without limitation at the then applicable Conversion Price.
	(iii)		The Make Whole Premium Shares shall be deemed to have been issued upon conversion of the Debentures on the Business Day immediately following the Effective Date. Article 6 shall apply to such conversion and, for greater certainty, the former Holders of Debentures in respect of which the Make Whole Premium Shares are issuable shall be entitled to receive and shall accept, in lieu of the Make Whole Premium Shares, the number of shares or other securities or property of the Corporation or of the Person or other entity resulting from the transaction that constitutes the Cash Change of Control that such Holders would have been entitled to receive if such Holders had been the registered holders of the applicable number of Make Whole Premium Shares on the Effective Date.

(iv)

Except as otherwise provided in this section 3.9(e), all other provisions of this Indenture applicable to a conversion of Debentures shall apply to a conversion of Debentures during the Cash Change of Control Conversion Period.

(f)

The Corporation will comply with all Applicable Securities Laws in the event that the Corporation is required to repurchase the Debentures pursuant to an Offer to Purchase in connection with a Change of Control and the Corporation’s obligations hereunder shall be subject to the requirements of all Applicable Securities Laws.

3.10 Cancellation of Redeemed, Purchased or Repurchased Debentures

All Debentures redeemed, purchased or repurchased in whole or in part pursuant to this Article 3 shall be forthwith delivered to and cancelled by the Indenture Trustee and may not be reissued or resold and no Debentures shall be issued in substitution therefor.

ARTICLE 4
CONVERSION

4.1 Conversion Right

	(a)		Each Holder shall have the right at any time prior to the close of business on the earlier of (i) the Business Day immediately preceding the Maturity Date or, (ii) if called for redemption under section 3.4, the Business Day immediately preceding the Redemption Date or, (iii) if called for repurchase pursuant to section 3.9, the Business Day immediately preceding the Payment Date, at his option to convert each $1,000 principal amount of his Debentures into that number of Common Shares equal to the Conversion Number, all on the terms and subject to the conditions provided in this Article 4, provided that the only shares issuable on conversion of the Debentures shall be shares that are “prescribed securities” as defined in Regulation 6208 of the Income Tax Act (Canada).
	(b)		In order to exercise his option to convert provided pursuant to section 4.1(a), a Holder will be required to deliver to the Indenture Trustee at the Corporate Trust Office or any other place specified in the Maturity Notice or the Redemption Notice or the Offer to Purchase, as the case may be, on or prior to the Business Day immediately preceding the Maturity Date, the Redemption Date or the Payment Date, as the case may be, a conversion notice in the form set forth in Schedule “C-1” (the “Conversion Notice”) (with a copy to the Corporation), duly completed and executed by the Holder or his executors or administrators or other legal representatives or his or their attorney duly appointed by instrument in form and execution satisfactory to the Indenture Trustee, together with the related Debentures (or such other documents as the Indenture Trustee may require in lieu thereof). The Conversion Notice shall specify the date of conversion (the “Conversion Date”) of the Debentures, which Conversion Date shall not be earlier than the date the Conversion Notice is delivered to the Indenture Trustee and shall not be later than the close of business on the Business Day immediately preceding the Maturity Date, the Redemption Date or the Payment Date.
	(c)		Upon receipt of a Conversion Notice from the Holder, the Corporation shall ensure that the following conditions are met:

	(i)		the Common Shares to be issued on conversion by the Holder shall be issued from treasury of the Corporation and shall be Freely Tradeable, fully paid and non-assessable Common Shares;
	(ii)		the listing or quoting of such additional Common Shares on each Recognized Stock Exchange;
	(iii)		the Corporation being a reporting issuer or equivalent in good standing or equivalent under Applicable Securities Laws in the provinces and territories of Canada in which the Corporation is a reporting issuer;
	(iv)		no Event of Default shall have occurred and be continuing; and
	(v)		the receipt by the Indenture Trustee of an Officer’s Certificate stating that conditions (i), (ii), (iii) and (iv) above have been satisfied and setting forth the number of Common Shares to be delivered for each $1,000 principal amount of Debentures, plus the accrued and unpaid interest thereon, and the calculation of the Conversion Number.

If the foregoing conditions are not satisfied prior to the close of business on the Business Day preceding the Conversion Date, the Corporation shall pay in cash the Conversion Value of the Debentures in lieu of delivery of the Conversion Number of Common Shares, unless such Debentureholder waives the conditions which are not satisfied or extends the time by which the Corporation is to satisfy such conditions.

4.2 Completion of Conversion

	(a)		Subject to section 4.1, within five Business Days of the Conversion Date, the Corporation shall deliver, or have the Transfer Agent deliver, to the Indenture Trustee on account of the Holder for delivery to each Holder who has elected to convert his Debentures pursuant to section 4.1, for each $1,000 principal amount of Debentures which the Holder has elected to convert: (i) certificates for the Common Shares to which the Holder is entitled; (ii) a certified cheque or bank draft in the amount of the value of a fractional Common Share, if any; (iii) a certified cheque or bank draft in the amount of the accrued and unpaid interest thereon, and (iv) if the Holder has elected to convert a principal amount of Debentures, together with the accrued and unpaid interest thereon (the “exercised amount”), which is less than the principal amount of all Debentures of which such person is the Holder immediately prior to such exercise (the “registered amount”), Debenture(s) registered in the name of such Holder in an aggregate principal amount equal to the amount by which the registered amount exceeds the exercised amount.
	(b)		All Debentures converted in whole or in part pursuant to this Article 4 shall be forthwith delivered to and cancelled by the Indenture Trustee and the Indenture Trustee shall amend the register maintained by it accordingly.
	(c)		The Corporation shall provide or cause to be provided to the Indenture Trustee the certificates for the Common Shares and for the Debentures to be delivered pursuant to section 4.2(a), if any, and pay to the Indenture Trustee sufficient funds, by certified cheque or bank draft, in a timely manner, to permit the Indenture Trustee, on behalf of the Corporation, to make the delivery required by section 4.2(a) and any other payments, if any, required by section 4.3. Except as provided herein, Debentures which have been converted may not be reissued or resold.

4.3 Fractional Shares

No fractional Common Shares shall be delivered upon the conversion of Debentures but, in lieu thereof, if such a fraction shall become owing, the Corporation shall pay to the Holders, or to the Indenture Trustee on account of the Holders if necessary, at the time contemplated in section 4.2(a), the cash equivalent thereof determined on the basis of the Current Market Price of Common Shares as at the Conversion Date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the Conversion Date).

4.4 Relating to the Issue of Common Shares

	(a)		A Holder shall be treated as the shareholder of record of the Common Shares issued on due conversion of his Debentures and the issuance of Common Shares shall be deemed to have occurred, for all purposes, effective immediately after the close of business on the Conversion Date; such Holder shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including stock dividends and dividends or distributions in kind) thereon and arising thereafter and in the event that the Indenture Trustee receives the same, it shall hold the same under gratuitous deposit for the benefit of such Holder.
	(b)		The Corporation shall at all times reserve and keep available out of its authorized Common Shares (if the number thereof is or becomes limited) solely for the purpose of issue and delivery upon the conversion of Debentures, and shall issue to Debentureholders who may exercise their conversion rights hereunder such number of Common Shares as shall be issuable in such events.
	(c)		The Corporation shall comply with all Applicable Securities Laws regulating the issue and delivery of Freely Tradeable Common Shares upon conversion of Debentures, shall obtain any regulatory approval in respect thereof as may be required pursuant to Applicable Securities Laws and shall cause to be listed and posted for trading such Common Shares on each Recognized Stock Exchange.

ARTICLE 5
MATURITY

5.1 Payment of Principal and Interest at Maturity

On the Maturity Date, the Corporation shall pay to the Debentureholders all the principal of the Debentures and all accrued and unpaid interest thereto, up to but excluding the Maturity Date. Subject to section 5.2, payment of principal and accrued and unpaid interest shall be made in cash or by cheque to the Holders in the manner contemplated by section 2.10 or 2.12, as the case may be.

5.2 Right to Repay Principal Amount in Common Shares at Maturity

(a)

The Corporation may, at its option and subject to receiving all applicable regulatory approvals, elect to satisfy its obligation to repay on the Maturity Date the principal amount of all, but not less than all, of the Debentures by delivering to the Holders and the Indenture Trustee not less than 40 days and not more than 60 days prior to the Maturity Date a maturity notice in the form of Schedule “C-2” (the “Maturity Notice”) and, on the Maturity Date, for each $1,000 principal amount of Debentures, by issuing and delivering to Holders that number of fully paid and non-assessable Freely Tradeable Common Shares obtained by dividing each $1,000 principal amount of Debentures by

			95% of the Current Market Price of the Common Shares on the Maturity Date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the Maturity Date) (the “Share Repayment Right”).
	(b)		The Corporation shall be required to provide the Maturity Notice only if it elects to exercise the Share Repayment Right.
	(c)		The Corporation’s right to exercise the Share Repayment Right shall be conditional upon the following conditions being met on the Business Day immediately preceding the Maturity Date:

	(i)		the Common Shares to be issued on exercise of the Share Repayment Right shall be issued from treasury of the Corporation and shall be fully paid and non-assessable Freely Tradeable Common Shares and free from any Security or adverse claim;
	(ii)		the listing or quoting of such additional Common Shares on each Recognized Stock Exchange on which the Common Shares are then listed;
	(iii)		the Corporation being a reporting issuer or equivalent in good standing or equivalent under Applicable Securities Laws in the provinces and territories of Canada in which the Corporation is a reporting issuer on Maturity;
	(iv)		no Event of Default shall have occurred and be continuing;
	(v)		the receipt by the Indenture Trustee of an Officer’s Certificate stating that conditions (i), (ii), (iii) and (iv) above have been satisfied and setting forth the number of Common Shares to be delivered for each $1,000 principal amount of Debentures and the Current Market Price of Common Shares on the Maturity Date; and
	(vi)		the receipt by the Indenture Trustee of an Opinion of Counsel to the effect that such Common Shares have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the principal amount of the Debentures outstanding, will be validly issued as fully paid and non-assessable, that conditions (i) and (ii) above have been satisfied and that, relying exclusively on certificates of good standing issued by the relevant securities regulatory authorities, condition (iii) above is satisfied, except that the opinion in respect of condition (iii) need not be expressed with respect to those provinces and territories where such certificates are not issued.

If the foregoing conditions are not satisfied by the close of business on the Business Day preceding the Maturity Date, the Corporation shall pay in cash 100% of the principal amount of the Debentures that would otherwise have been satisfied in Common Shares, unless the Debentureholder waives the conditions which are not satisfied or extends the time by which the Corporation is to satisfy such conditions.

(d)

In the event that the Corporation exercises its Share Repayment Right, the Corporation shall, on the Maturity Date, deliver or cause to be delivered to the Indenture Trustee for delivery to and on account of the Holders, certificates representing the Freely Tradeable Common Shares to which such Holders are entitled and a cheque representing all of the

			accrued and unpaid interest up to but excluding the Maturity Date. Upon presentation and surrender of the Debentures (or such other documents as the Indenture Trustee may require in lieu thereof) by a Holder for payment at Maturity at the Corporate Trust Office or any other place specified in the Maturity Notice, the Indenture Trustee shall deliver the certificates representing such Common Shares and the cheque representing all the accrued and unpaid interest and the cash equivalent representing the value of fractional shares, if any.
	(e)		No fractional Common Shares shall be delivered upon the exercise of the Share Repayment Right but, in lieu thereof, if such a fraction shall become owing, the Corporation shall pay to the Indenture Trustee for the account of the Holders, at the time contemplated in section 5.2(d), the cash equivalent thereof determined on the basis of the Current Market Price of the Common Shares on the Maturity Date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the Maturity Date).
	(f)		A Holder shall be treated as the shareholder of record of the Common Shares issued on due exercise by the Corporation of its Share Repayment Right effective immediately after the close of business on the Maturity Date, and shall be entitled to all substitutions therefor, all income earned thereon or accretions thereto and all dividends or distributions (including stock dividends and dividends or distributions in kind) thereon and arising thereafter, and in the event that the Indenture Trustee receives the same, it shall hold the same under gratuitous deposit for the benefit of such Holder.
	(g)		The Corporation shall at all times reserve and keep available out of its authorized Common Shares (if the number thereof is or becomes limited) solely for the purpose of issue and delivery upon the exercise of the Share Repayment Right as provided herein, and shall issue to Debentureholders to whom Common Shares will be issued pursuant to the exercise of the Share Repayment Right, such number of Common Shares as shall be issuable in such event.
	(h)		The Corporation shall comply with all Applicable Securities Laws regulating the issue and delivery of Freely Tradeable Common Shares upon exercise of the Share Repayment Right, shall obtain any regulatory approval in respect thereof as may be required pursuant to Applicable Securities Laws and shall cause to be listed and posted for trading such Common Shares on each Recognized Stock Exchange.
	(i)		If the Corporation elects to satisfy its obligation to pay the principal amount of the Debentures by issuing Common Shares pursuant to the Share Repayment Right and the delivery of Common Shares to which a Holder is entitled is subject to withholding Taxes, the Corporation shall satisfy the payment of such withholding Taxes pursuant to section 2.15.

ARTICLE 6
ADJUSTMENTS

6.1 Adjustment of Conversion Price

The Conversion Price in effect at any date will be subject to adjustment from time to time without duplication in the events and in the manner provided as follows.

(a)

If and whenever at any time after the date hereof and prior to the Maturity Date, the Corporation:

	(i)		subdivides its outstanding Common Shares into a greater number of Common Shares; or
	(ii)		reduces, combines or consolidates its outstanding Common Shares into a smaller number of Common Shares; or
	(iii)		issues Common Shares or securities convertible into or exchangeable for Common Shares to the holders of all or substantially all of the outstanding Common Shares as a dividend, distribution or otherwise (other than an issue of Common Shares or securities convertible into or exchangeable for Common Shares to holders of Common Shares pursuant to a right granted to such holders to receive such Common Shares in lieu of Dividends Paid in the Ordinary Course);

			(any of such events in clauses (i), (ii) and (iii), being called a “Common Share Reorganization”), then the Conversion Price will be adjusted, effective on the effective date or record date for the happening of a Common Share Reorganization, as the case may be, at which the holders of Common Shares are determined for the purpose of the Common Share Reorganization, so that it shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such effective date or record date by a fraction, the numerator of which will be the total number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Reorganization and the denominator of which will be the total number of Common Shares outstanding immediately after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number of Common Shares that would have been outstanding had all such securities been exchanged for or converted into Common Shares on such effective date or record date).
	(b)		If and whenever at any time after the date hereof and prior to the Maturity Date, the Corporation fixes a record date for the issue of rights, options or warrants to the holders of all or substantially all of the outstanding Common Shares under which such holders are entitled, during a period expiring not more than 45 days after the record date for such issue (the “Rights Period”), to subscribe for or purchase Common Shares or securities exchangeable for or convertible into Common Shares at a price per share to the holder (or at an exchange price or conversion price per share during the Rights Period to the holder in the case of securities exchangeable for or convertible into Common Shares) which is less than 95% of the Current Market Price for the Common Shares on such record date (any of such events being called a “Rights Offering”), then the Conversion Price will be adjusted effective immediately after the end of the Rights Period so that it shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the end of the Rights Period by a fraction:

(i)

the numerator of which will be the aggregate of:

(A)

the total number of Common Shares outstanding as of the record date for the commencement of the Rights Offering, and

(B)

a number determined by dividing (1) either (x) the product of the number of Common Shares issued or subscribed for during the Rights Period upon the exercise of the rights, warrants or options under the Rights Offering and the price at which such Common Shares are offered for such issue or subscription, or, as the case may be, or (y) the product of the exchange price or conversion price of such securities exchangeable for or convertible into Common Shares and the number of Common Shares for or into which the securities so offered pursuant to the Rights Offering could have been exchanged or converted during the Rights Period, by (2) the Current Market Price of the Common Shares as of the record date for the commencement of the Rights Offering, and

(ii)

the denominator of which will be the number of Common Shares outstanding, or the number of Common Shares which would be outstanding if all the exchangeable or convertible securities were exchanged for or converted into Common Shares during the Rights Period, after giving effect to the Rights Offering and including the number of Common Shares actually issued or subscribed for during the Rights Period upon exercise of the rights, warrants or options under the Rights Offering.

	(c)		Any Debentureholder who has exercised the right to convert to Common Shares in accordance with Article 4 during the period beginning immediately after the record date for a Rights Offering and ending on the last day of the Rights Period for the Rights Offering will, in addition to the Common Shares to which that holder would otherwise be entitled upon such conversion, be entitled to that number of additional Common Shares equal to the result obtained when the difference, if any, between the Conversion Price in effect immediately prior to the end of such Rights Offering and the Conversion Price as adjusted for such Rights Offering pursuant to this section 6.1(c) is multiplied by the number of Common Shares received upon the conversion of the Debentures held by such Holder during such period, and the resulting product is divided by the Conversion Price as adjusted for such Rights Offering pursuant to this section 6.1(c); provided that the provisions of section 4.3 will be applicable to any fractional interest in a Common Share to which such Holder might otherwise be entitled under the foregoing provisions of this section 6.1(c). Such additional Common Shares will be deemed to have been issued to the Debentureholder immediately following the end of the Rights Period and a certificate for such additional Common Shares will be delivered to such Holder within 15 Business Days following the end of the Rights Period. To the extent that any such rights, options or warrants are not so exercised on or before the expiry thereof, the Conversion Price will be readjusted to the Conversion Price which would then be in effect based on the number of Common Shares (or the securities convertible into or exchangeable for Common Shares) actually delivered on the exercise of such rights, options or warrants.
	(d)		If and whenever at any time after the date hereof and prior to the Maturity Date, the Corporation fixes a record date for the issue or the distribution to the holders of all or substantially all of the outstanding Common Shares of (i) securities of the Corporation, including rights, options or warrants to acquire securities of the Corporation or any of its property or assets and including cash and evidences of Indebtedness; or (ii) any property or other assets, including cash and evidences of Indebtedness, and if such issuance or distribution does not constitute a Dividend Paid in the Ordinary Course, a Common Share Reorganization, a Rights Offering or a distribution contemplated by section 6.1(b) (any of such non-excluded events being called a “Special Distribution”), then the Conversion Price will be adjusted effective 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:

(i)

the numerator of which will be:

	(A)		the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such record date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding such record date); less
	(B)		the fair market value (in US Dollars), as determined by action by the Board of Directors (whose determination, subject to the consent of a Recognized Stock Exchange, will be conclusive), to the holders of Common Shares of such securities or property or other assets so issued or distributed in the Special Distribution; and

(ii)

the denominator of which will be the product of the number of Common Shares outstanding on such record date and the Current Market Price of the Common Shares on such record date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding such record date).

			To the extent that any Special Distribution is not so made, the Conversion Price will be readjusted effective immediately to the Conversion Price which would then be in effect based upon such securities or property or other assets as actually distributed.
	(e)		If and whenever at any time after the date hereof and prior to the Maturity Date, there is a reclassification of the Common Shares at any time outstanding or change of the Common Shares into other shares or into other securities or other capital reorganization (other than a Common Share Reorganization), or a consolidation, amalgamation or merger of, or an arrangement involving, the Corporation with or into any other corporation or other entity (other than a vertical amalgamation with one or more of its Wholly-Owned Subsidiaries pursuant to the Business Corporations Act (Ontario)), or a transfer of the undertaking or assets of the Corporation as an entirety or substantially as an entirety to another corporation or other entity in which the holders of Common Shares are entitled to receive shares, other securities or other property (any of such events being called a “Capital Reorganization”), any Holder who exercises the right to convert Debentures into Common Shares pursuant to Debentures then held after the effective date of such Capital Reorganization will be entitled to receive, and will accept for the same aggregate consideration in lieu of the number of Common Shares to which such Holder was previously entitled upon such conversion, the aggregate number of shares, other securities or other property which such holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, the holder had been the registered holder of the number of Common Shares to which such holder was previously entitled upon conversion provided, however, that the consideration into which the Debentures will be convertible will be limited to prescribed securities (as defined by Regulation 6208 to the Income Tax Act (Canada)) of the Corporation as specified by the Board of Directors of the Corporation. The Corporation will take all steps necessary to ensure that, on a Capital Reorganization, the Debentureholders will receive the aggregate number of shares, other securities or other property to which they are entitled as a result of the Capital Reorganization and that such shares or securities will be prescribed

			securities as defined in Regulation 6208 of the Income Tax Act (Canada), which includes shares or securities not redeemable by the holder thereof within 5 years from the issue date of the Debentures. Appropriate adjustments will be made as a result of any such Capital Reorganization in the application of the provisions set forth in this Article 6 with respect to the rights and interests thereafter of Debentureholders to the end that the provisions set forth in this Article 6 will thereafter correspondingly be made applicable as nearly as may reasonably be in relation to any shares, other securities or other property thereafter deliverable upon the conversion of any Debenture. Prior to or concurrent with effecting a Capital Reorganization, the Corporation or any such successor, purchasing or transferee corporation or entity, as the case may be, will enter into an indenture supplemental hereto approved by action of the Board of Directors and by the Indenture Trustee, which will set forth an appropriate adjustment to give effect to this section 6.1(e), in which event such adjustment will for all purposes be conclusively deemed to be an appropriate adjustment, subject to the prior written consent of a Recognized Stock Exchange.
	(f)		If the purchase price provided for in any rights, options or warrants (the “Rights Offering Price”) referred to in sections 6.1(b) or 6.1(d) is decreased, the Conversion Price will forthwith be changed so as to decrease the Conversion Price to the Conversion Price that would have been obtained if the adjustment to the Conversion Price made under sections 6.1(b) or 6.1(d), as the case may be, with respect to such rights, options or warrants had been made on the basis of the Rights Offering Price as so decreased, provided that the terms of this section 6.1(f) will not apply to any decrease in the Rights Offering Price resulting from terms in any such rights, options or warrants designed to prevent dilution except to the extent that the resulting decrease in the Conversion Price under this section 6.1(f) would be greater than the decrease, if any, in the Conversion Price to be made under the terms of this section by virtue of the occurrence of the event giving rise to such decrease in the Rights Offering Price.
	(g)		In any case in which this section 6.1 shall require that an adjustment shall become effective immediately after a record date for an event referred to herein, the Corporation may 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 Common Shares issuable upon such conversion by reason of the adjustment required by such event, provided, however, that the Corporation shall deliver to such Holder an appropriate instrument evidencing such Holder’s right to receive such additional Common Shares upon the occurrence of such event and the right to receive any distributions made on such additional Common Shares declared in favour of holders of record of Common Shares on and after the date of conversion or such later date on which such Holder would, but for the provisions of this section 6.1(g), have become the holder of record of such additional Common Shares. Such additional Common Shares so issued shall be prescribed securities as defined in Regulation 6208 of the Income Tax Act (Canada).

6.2 Other Adjustment of Conversion Price

If the Corporation shall take any action affecting the Common Shares, other than an action described in sections 6.1(a), 6.1(b), 6.1(d) or 6.1(f) but including an action under section 6.1(e), which results in a Holder being unable, for any period of time, to exercise conversion privileges that it would otherwise be permitted to exercise due to requirements necessary to ensure that the Debentures will be and will remain exempt from Canadian withholding taxes, the Conversion Price may be adjusted in such manner and at such time, or such other adjustment to the conversion privilege may be made, as the Board of Directors

determine to be equitable in the circumstances, subject to the prior written consent of a Recognized Stock Exchange. Failure of the Board of Directors to take any such action shall be conclusive evidence that the Board of Directors has determined that it is equitable to make no adjustment in the circumstances.

6.3 Rules Regarding Calculation of Adjustment of Conversion Price

For the purposes of sections 6.1 and 6.2:

	(a)		The adjustments are cumulative and will be computed to the nearest one-tenth of one cent and will be made successively whenever an event referred to therein occurs, subject to the following paragraphs of this section.
	(b)		No adjustment in the Conversion Price will be required unless the cumulative effect of such adjustment would result in a change of at least 1% in the prevailing Conversion Price; provided, however, that any adjustments which, except for the provisions of this section 6.3(b) would otherwise have been required to be made, will be carried forward and taken into account in any subsequent adjustment.
	(c)		No adjustment in the Conversion Price will be required upon the issuance from time to time of Common Shares pursuant to the Corporation’s stock option plans or share purchase plan, or any dividend reinvestment plan, or any similar plan, if any, as such plans may be replaced, supplemented or further amended from time to time. In addition, for greater certainty, no adjustment in the Conversion Price upon an event referred to in section 6.1(d) will be required upon the distribution from time to time of Common Shares by way of private placement or prospectus which is made to the public in general.
	(d)		No adjustment in the Conversion Price will be made in respect of sections 6.1(a)(iii), 6.1(b) or 6.1(d), if Debentureholders are entitled to participate in such event on the same terms, mutatis mutandis, as if they had converted their Debentures prior to or on the effective date or record date of such event. Any such participation will be subject to any required prior consent of a Recognized Stock Exchange.
	(e)		If at any time a dispute arises with respect to adjustments provided for in section 6.1, such dispute will be conclusively determined, subject to the consent of a Recognized Stock Exchange, by the Corporation’s auditors, or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by action of the Board of Directors and any such determination will be binding upon the Corporation, the Indenture Trustee, the Debentureholders and shareholders of the Corporation; such auditors or accountants will be given access to all necessary records of the Corporation. If any such determination is made, the Corporation will deliver an Officer’s Certificate to the Indenture Trustee describing such determination, and the Indenture Trustee shall be entitled to act and rely upon such Officer’s Certificate.
	(f)		If the Corporation sets a record date to determine the holders of Common Shares for the purpose of entitling them to receive any dividend or distribution or sets a record date to take any other action and thereafter and before the distribution to such shareholders of any such dividend or distribution or the taking of any other action, legally abandons its plan to pay or deliver such dividend or distribution or take such other action, then no adjustment in the Conversion Price shall be made.
	(g)		In the absence of a resolution of the Board of Directors fixing a record date for a Special Distribution or Rights Offering, the Corporation will be deemed to have fixed as the

			record date therefor the date on which the Special Distribution or Rights Offering is effected.
	(h)		For greater certainty, Debentureholders shall have no right to convert Debentures into any security other than Common Shares unless an appropriate adjustment is made by and set forth in an indenture supplemental hereto.

6.4 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 6.1 and 6.2, deliver an Officer’s Certificate to the Indenture Trustee specifying the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, and the Indenture Trustee shall be entitled to act and rely upon such Officer’s Certificate. Such Officer’s Certificate and the amount of the adjustment specified therein shall be conclusive and binding on all parties in interest. Until such Officer’s Certificate is received by the Indenture Trustee, the Indenture Trustee may act and be protected in acting on the presumption that no adjustment has been made or is required. Except in respect of any subdivision, reduction, combination or consolidation of the Common Shares contemplated by sections 6.1(a)(i) and (ii), the Corporation shall forthwith give notice to the Debentureholders specifying the event requiring such adjustment or readjustment and the amount thereof, including the resulting Conversion Price; provided that if the Corporation has given notice under section 6.5 covering all the relevant facts in respect of such event, no such notice need be given under this section 6.4.

6.5 Notice of Special Matters

The Corporation covenants that, so long as any Debentures remain Outstanding, it will give notice to the Indenture Trustee on account for the Debentureholders of its intention to fix a record date for any event referred to in sections 6.1(a), (b), (d) or 6.1(e) (other than the subdivision, reduction, combination or consolidation of Common Shares contemplated by sections 6.1(a)(i) and 6.1(a)(ii)) or a cash dividend (other than a Dividend Paid in the Ordinary Course) which may give rise to an adjustment in the Conversion Price, or other adjustment, and 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 14 days and not more than 60 days prior to the applicable record date in the case of an event referred to in sections 6.1(a), (b) or (d) and not less than 21 days and not more than 60 days prior to the applicable record date in the case of an event referred to in section 6.1(e).

6.6 Notice of Expiry of Conversion Right

The Corporation covenants that, so long as any Debentures remain Outstanding, it will give notice to the Indenture Trustee on account for the Debentureholders in the manner provided in Article 16, not less than 21 days prior to the Maturity Date, the Redemption Date or the Payment Date, as the case may be, of the expiry of the right of the Holders of the Debentures to convert their Debentures pursuant to section 4.1(a).

6.7 Protection of Trustee

The Indenture Trustee shall not at any time be under any duty or responsibility to any Debentureholder to determine whether any facts exist which may require any adjustment in the Conversion Price, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed in making the same; and shall not be accountable with respect to the validity or value (or the

kind or amount) of any Common Shares or of any shares or other securities or other property which may at any time be issued or delivered upon the conversion of any Debenture; and the Indenture Trustee, except to the extent that the Indenture Trustee has acted with wilful misconduct or gross negligence, shall not be responsible for any failure of the Corporation to make any cash payment or to issue, transfer or deliver Common Shares or share certificates upon the surrender of any Debenture for the purpose of conversion, or to comply with any of the covenants contained in this Article 6.

	(c)		The Indenture Trustee shall not incur any liability or be in any way responsible for the consequences of any loss caused by the investment referred to in section 7.1(b)(iv) and the Corporation indemnifies and saves harmless the Indenture Trustee and its officers, directors, employees and agents from and against any and all liabilities, losses, costs, claims, actions, expenses or demands whatsoever which may be brought against the Indenture Trustee or which it may suffer or incur as a result of performing its obligations set out in section 7.1(b).

	(d)		The Common Share Interest Payment Election Notice shall provide for, and all bids shall be subject to, the right of the Corporation, by delivering written notice to the Indenture Trustee at any time prior to the consummation of such delivery and sale of the Common Shares on the Common Share Delivery Date, to withdraw the Common Share Interest Payment Election (which shall have the effect of withdrawing each related Common Share Bid Request), whereupon the Corporation shall be obliged to pay in cash the Interest Obligation in respect of which the Common Share Interest Payment Election Notice has been delivered.
	(e)		Any sale of Common Shares pursuant to this Article 7 may be made to one or more Persons whose bids are solicited, but all such sales with respect to a particular Common Share Interest Payment Election shall take place concurrently on the Common Share Delivery Date.
	(f)		The amount received by a Holder of a Debenture in respect of the Interest Obligation will not be affected by whether or not the Corporation elects to satisfy the Interest Obligation pursuant to a Common Share Interest Payment Election.

Upon such deliveries, the Indenture Trustee shall consummate such sales on such Common Share Delivery Date by the delivery of the Common Shares to such purchasers against payment to the Indenture Trustee in immediately available funds of the purchase price therefor.

The Indenture Trustee shall remit amounts, if any, in respect of income earned on the Common Share Proceeds Investment or otherwise in excess of the Common Share Interest Payment Election Amount to the Corporation.
	(j)		Neither the making of a Common Share Interest Payment Election nor the consummation of sales of Common Shares on a Common Share Delivery Date will (i) result in the Holders not being entitled to receive on the applicable Interest Payment Date cash in an aggregate amount equal to the Interest Obligation payable on such date, or (ii) entitle such Holders to receive any Common Shares in satisfaction of such Interest Obligation.

No payment or distribution of assets of the Corporation to the Debentureholders which would be payable or distributable to the holders of Senior Indebtedness pursuant to this Article 8 shall, as between the Corporation, its creditors (other than the holders of Senior Indebtedness) and the Debentureholders, be deemed to be a payment by the Corporation to or on account of the Debentureholders, it being understood that the provisions of this Article 8 are, and are intended, solely for the purpose of defining the relative rights of the Debentureholders, on the one hand, and the holders of the Senior Indebtedness, on the other hand. Nothing contained in this Article 8 or elsewhere in this Indenture or in the Debentures is intended to or shall impair, as between the Corporation and its creditors (other than the holders of Senior Indebtedness and the Debentureholders), the obligation of the Corporation, which is unconditional and absolute, to pay to the Debentureholders the principal of and interest on the Debentures, as and when the same shall become due and payable in accordance with their terms, or to affect the relative rights of the Debentureholders and the creditors of the Corporation, other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Indenture Trustee or the Holder of any Debentures from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 8, of the holders of Senior Indebtedness upon the exercise of any such remedy.

The fact that any such payment is prohibited by section 8.2 or 8.4 shall not prevent the failure to make such payment from being an Event of Default hereunder.

8.6

Authorization of Debentureholders to Trustee to Effect Subordination

Each Holder, by his acceptance thereof, authorizes and directs the Indenture Trustee, on its behalf, to execute and deliver any such subordination agreements with the Corporation and the holders, or representatives or trustees thereof, of Senior Indebtedness, whether outstanding or hereafter Incurred, which Counsel shall advise contains the subordination provisions hereof and as may be necessary in the

8.8

Trustee May Hold Senior Indebtedness

8.9

Rights of Holders of Senior Indebtedness Not Impaired

No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein will at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Corporation or by any non-compliance by the Corporation with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

Altering the Senior Indebtedness

The holders of the Senior Indebtedness have the right to extend, renew, modify or amend the terms of the Senior Indebtedness or any security therefor and to release, sell or exchange such security and otherwise to deal freely with the Corporation, all without notice to or consent of the Debentureholders or the Indenture Trustee and without affecting the liabilities and obligations of the parties to this Indenture or the Debentureholders or the Indenture Trustee.

8.11

In the event the Corporation is no longer subject to the continuous disclosure requirement of Applicable Securities Laws, the Corporation shall continue to provide to the Indenture Trustee and the Holders (a) within 90 days after the end of each fiscal year, copies of its annual report and annual financial statements, and (b) within 45 days after the end of each of the first three fiscal quarters of each fiscal year, interim financial statements which shall, at a minimum, contain such information required to be provided in quarterly reports under the Applicable Securities Laws in the provinces and territories of Canada in which the Corporation, as at the date hereof, is a “reporting issuer” (as such term is defined in such Applicable Securities Laws). Each of such reports will be prepared in accordance with disclosure requirements of Applicable Securities Laws of the provinces and territories of Canada in which the Corporation, as at the date hereof, is a “reporting issuer” (as such term is defined in such Applicable Securities Laws) and Canadian generally accepted accounting principles.

9.7

Maintain Listings

The Corporation will use reasonable commercial efforts to maintain the listing of the Common Shares and the Debentures on the TSX and, if the Common Shares are listed on the NASDAQ, on the NASDAQ, and to maintain the Corporation’s status as a “reporting issuer” not in default of the requirements of the Applicable Securities Legislation, provided that the foregoing covenant shall not prevent or restrict the Corporation from carrying out a transaction to which section 3.9 or Article 14 would apply if carried out in compliance with section 3.9 or Article 14, respectively, even if as a result of such transaction the Common Shares or the Debentures cease to be listed on the TSX or a Recognized Stock Exchange or the Corporation ceases to be a “reporting issuer”.

9.8

Performance of Covenants by Indenture Trustee

If the Corporation fails to perform any of its covenants contained in this Indenture, the Indenture Trustee may itself perform any of such covenants capable of being performed by it, but will be under no obligation to do so. All sums expended or advanced by the Indenture Trustee for such purpose will be repayable as provided in section 9.9 of the Indenture. No such performance or advance by the Indenture Trustee shall relieve the Corporation of any default hereunder or its continuing obligations hereunder.

9.9

Payment of Indenture Trustee’s Remuneration

The Corporation will pay the Indenture Trustee’s reasonable remuneration for its services as Indenture Trustee hereunder (including reimbursement for distributions which include legal services) and will repay to the Indenture Trustee on demand all moneys which shall have been paid by the Indenture Trustee out of its own funds in and about the execution of the trusts hereby created. Any moneys owed to the Indenture Trustee which remain unpaid for a period of 30 days or more from the issue date of the Indenture Trustee’s invoice for such moneys owed shall bear interest at the rate charged by the Indenture Trustee from time to time to its corporate trust customers until the date of payment. All such moneys shall be paid by the Corporation immediately upon receipt of such invoice by the Corporation. The said

remuneration shall continue to be payable until the trusts hereof are finally wound up and whether or not the trusts of this Indenture shall be in course of administration by or under the direction of the court. This section 9.9 shall survive the resignation of the Indenture Trustee or the termination of this Agreement. Notwithstanding the foregoing, the Corporation need not pay or reimburse the Indenture Trustee for expenses, disbursements or advances if the Indenture Trustee incurred such expenses, disbursements or advances as a result of its dishonesty, bad faith, wilful misconduct, negligence or reckless disregard of a right, duty or obligation by the Indenture Trustee.

	(e)		the failure to make an Offer to Purchase upon a Change of Control;
	(f)		a decree, judgment, or order by a court having jurisdiction in the premises shall have been entered adjudging the Corporation bankrupt or insolvent or approving as properly filed a petition seeking reorganization, readjustment, arrangement, composition or similar relief for the Corporation, under the Bankruptcy and Insolvency Act (Canada) or any other bankruptcy, insolvency or analogous applicable law of Canada or any province thereof, and such decree, judgment or order of a court having jurisdiction in the premises for the appointment of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of the Corporation or of a substantial part of its property, or for the winding up or liquidation of its affairs, shall have remained in force for a period of 60 consecutive days; or any substantial part of the property of the Corporation shall be sequestered or attached and shall not be returned to the possession of the Corporation or released from such attachment, as the case may be, whether by filing of a bond, or stay or otherwise, within 60 consecutive days thereafter; or

then, and in each and every such case which has happened and is continuing, the Indenture Trustee may, in its discretion, and shall, upon the written request of the Holders of not less than 50% in principal amount of the Outstanding Debentures at such time (or, if there is a Global Debenture Outstanding, a written request of the Participants having received instructions from the Beneficial Holders holding at least 50% of the Outstanding Debentures), declare the principal of (and premium, if any) together with accrued interest on all such Debentures to be due and payable immediately, by a Notice in writing to the Corporation (and to the Indenture Trustee if given by the Holders), and upon any such declaration such principal amount and premium, if any, together with accrued interest thereon, shall become immediately due and payable. If the Indenture Trustee fails to notify in writing the Corporation pursuant to the terms hereof, the Debentureholders having provided the written request to the Indenture Trustee may do so.

10.2

Notice of Event of Default

The Indenture Trustee shall give to the Holders within five days after the Indenture Trustee becomes aware by way of written Notice of the occurrence of an Event of Default, Notice of every Event of Default so occurring and continuing at the time the Notice is given, unless the Indenture Trustee reasonably and in good faith determines that the withholding of such Notice is in the best interests of the Holders and gives written Notice of such determination to the Corporation. When a Notice of the occurrence of an Event of Default is given by the Indenture Trustee pursuant to this section 10.2 and the Event of Default is thereafter waived, the Indenture Trustee shall give Notice that the Event of Default is no longer outstanding to all Holders to whom Notice of the occurrence of the Event of Default was given within five days after the Indenture Trustee becomes aware, by written Notice given by the Corporation to the Indenture Trustee, that the Event of Default has been waived and is no longer outstanding.

10.3

Waiver of Declaration

At any time after a declaration of acceleration with respect to the Debentures has been made pursuant to section 10.1 and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereinafter provided, the Holders of not less than 50% in principal amount of Outstanding Debentures, by written Notice to the Corporation and the Indenture Trustee, may thereupon rescind and annul such declaration and its consequences if the Corporation has paid or deposited with the Indenture Trustee a sum sufficient to pay:

	(a)		all overdue interest on all Debentures;
	(b)		the principal of (and premium, if any) any of the Debentures which have become due otherwise than by such declaration of acceleration, and interest thereon at the rate or rates prescribed therefor in such Debentures; and
	(c)		to the extent that payment of such interest is lawful and applicable, interest upon overdue instalments of interest at the rate or rates prescribed therefor in such Debentures; and

all Events of Default with respect to the Debentures, other than the non-payment of the principal of (and premium, if any), and interest on, such Debentures which have become due solely by such declaration of acceleration, have been cured or waived in accordance with the provisions of this Indenture.

10.4

Waiver

(a)

The Holders of not less than 50% in aggregate principal amount of the Outstanding Debentures may on behalf of the Holders of all Debentures waive any past default hereunder and its consequences, except a default:

	(i)		in the payment of the principal of (or premium, if any) or interest on any Debentures; or
	(ii)		in respect of a covenant or provision hereof that under Article 17 cannot be modified or amended without an Extraordinary Resolution passed by the Holders.

(b)

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

10.5

Other Remedies

	(a)		If an Event of Default occurs and is continuing, the Indenture Trustee may pursue any available remedy to collect the payment of principal of (and premium, if any) or interest on Debentures or to enforce the performance of any term of the Debentures or this Indenture.
	(b)		The Indenture Trustee may maintain a Proceeding even if it does not possess any Debentures or does not produce any of them in the Proceeding. A delay or omission by the Indenture Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default.

10.6

Application of Money Collected

Any money collected by the Indenture Trustee pursuant to this Article in respect of Debentures shall (subject to any claims having priority under Applicable Law) be applied in the following order, at the dates fixed by the Indenture Trustee and, in case of the distribution of such money on account of principal of (and premium, if any) or interest, upon presentation of Debentures and the notation thereon of the payment (if only partially paid) and upon surrender thereof (if fully paid):

	(a)		first, to the payment of all amounts due to the Indenture Trustee under this Indenture with respect to such Debentures;
	(b)		second, to the payment of accrued interest on such Debentures;
	(c)		third, to the payment of the principal of (and premium, if any) on such Debentures;

Control by Holders

	(a)		direct the time, method and place in the Province of Ontario of conducting any Proceeding for any remedy available to the Indenture Trustee or exercising any trust or power conferred on it with respect to the Debentures; and
	(b)		take any other action authorized to be taken by or on behalf of the Holders of any specified aggregate principal amount of Debentures under any provisions of this Indenture or under Applicable Law.

The Indenture Trustee may refuse, however, to follow any direction that conflicts with law or this Indenture.

10.8

Limitation on Suits

	(a)		No Holder of any Debenture will have any right to pursue any remedy (including any action, suit or proceeding authorized or permitted by this Indenture or pursuant to Applicable Law) with respect to this Indenture or the Debentures unless: (i) the Holder gives to the Indenture Trustee notice of a continuing Event of Default; (ii) the Holders of at least 25% in principal amount of the then Outstanding Debentures make a request in writing to the Indenture Trustee to pursue the remedy; (iii) such Holder or Holders offer or provide to the Indenture Trustee security and indemnity in form satisfactory to the Indenture Trustee against any loss, liability or expense; (iv) the Indenture Trustee does not comply with the request within 30 days after receipt of such request and indemnity; and (v) during such 30 day period the Holders of a majority in principal amount of Outstanding Debentures do not give the Indenture Trustee a direction inconsistent with the request.
	(b)		Holders may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

10.9

Collection Suit by Indenture Trustee

If an Event of Default specified in clause (a), (b), (c) or (d) of section 10.1 occurs and is continuing, the Indenture Trustee may recover judgment in its own name and as trustee against the Corporation for the whole amount of principal (and premium, if any) and interest remaining unpaid.

10.10

Indenture Trustee May File Proofs of Claim

The Indenture Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee and the Holders lodged or allowed in any judicial proceedings relative to the Corporation, its creditors or its property.

10.11

Undertaking for Costs

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Indenture Trustee for any action taken or omitted by it as Indenture Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defences made by the

party litigant. This section 10.11 does not apply to a suit by the Indenture Trustee, a suit by a Holder pursuant to section 10.8, or a suit by any Holder or group of Holders of more than 50% in principal amount of the Outstanding Debentures.

10.12

Delay or Omission Not Waiver

No delay or omission of the Indenture Trustee or of any Holder of any Debenture to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Indenture Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Holders, as the case may be.

10.13

Remedies Cumulative

No remedy herein conferred upon or reserved to the Indenture Trustee or upon or to the Holders is intended to be exclusive of any other remedy, but each remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now existing or hereafter to exist by law or statute.

10.14

Judgment Against the Corporation

The Corporation covenants and agrees with the Indenture Trustee that, in case of any Proceeding to obtain judgment for payment of the principal of, premium, if any, or interest, if any, on the Debentures, judgment may be rendered against it in favour of the Holders or in favour of the Indenture Trustee, as holder of a power of attorney for the Holders, for the amount which may remain due in respect of the Debentures and the interest and premium, if any, thereon.

ARTICLE 11
SATISFACTION AND DISCHARGE

11.1

Non-Presentation of Debentures

If any Debentureholder fails to present any Debentures for payment on the date on which the principal of, premium, if any, or interest thereon, becomes payable, whether on a Redemption Date, Payment Date, Maturity Date or any other repayment date, or shall not accept payment on account thereof and give such receipt therefor, if any, as the Indenture Trustee may require:

	(a)		the Corporation shall thereafter be entitled to pay or deliver to the Indenture Trustee and direct the Indenture Trustee to set aside,
	(b)		in respect of moneys or Common Shares in the hands of the Indenture Trustee which may or should be applied to the payment of the Debentures, the Corporation shall thereafter be entitled to direct the Indenture Trustee to set aside, or
	(c)		if the redemption was made pursuant to any Notice given by the Indenture Trustee, the Indenture Trustee may itself thereafter set aside,

the principal of, premium, if any, and interest on such Holder’s Debentures, in trust to be paid to such Debentureholder upon due presentation or surrender of such Debentures in accordance with the provisions of this Indenture; and thereupon the principal of, premium, if any, and interest payable on each Debenture in respect whereof such moneys and, if permitted hereunder, Common Shares have been set aside shall be deemed to have been paid and the Holder thereof shall thereafter have no right in respect thereof except to receive delivery and payment of the moneys or Common Shares, if applicable, so set

aside by the Indenture Trustee upon due presentation and surrender thereof, subject to the provisions of section 2.4. For greater certainty, the provisions of Article 6 shall not prevent the application of moneys received by the Trustee pursuant to this section 11.1 to the payment of principal, premium, if any, and interest on such Holder’s Debentures.

11.2

Repayment of Unclaimed Moneys or Common Shares

Any moneys or Common Shares, if applicable, set aside under section 11.1 and not claimed by and paid to the Holders as provided in section 11.1 within three years after the date of such setting aside shall be repaid and delivered to the Corporation by the Indenture Trustee on demand and thereupon the Indenture Trustee shall be released from all further liability with respect to such moneys or Common Shares, if applicable, and thereafter the holders of the Debentures in respect of which such moneys or Common Shares, if applicable, were so repaid to the Corporation shall have no rights in respect thereof except to obtain payment and delivery of the moneys or Common Shares, if applicable, due thereon from the Corporation up to such time as the right to proceed against the Corporation for recovery of such moneys or Common Shares, if applicable, has become statute barred under the laws of the Province of Ontario.

11.3

Discharge

The Indenture Trustee shall at the written request of the Corporation release and discharge this Indenture and execute and deliver such instruments as it shall be advised by Counsel are requisite for that purpose and release the Corporation from its covenants herein contained (other than the provisions relating to the indemnification of the Indenture Trustee), upon proof being given to the reasonable satisfaction of the Indenture Trustee that the principal of, premium, if any, and interest (including interest on amounts in default, if any) on all of the Debentures and all other moneys payable hereunder have been paid or satisfied or that, all of the Debentures having matured or having been duly called for redemption, payment of the principal of, premium, if any, and interest (including interest on amounts in default, if any) on such Debentures and all other moneys payable hereunder have been duly and effectually provided for in accordance with the provisions hereof.

In addition to any other provisions of this Indenture, the Indenture Trustee may, at any time any action is taken which relates to any of paragraphs (a) through (c) below, and acting in good faith, require evidence of compliance with the conditions precedent provided for in this Indenture relating to:

In its personal capacity or any other capacity, the Indenture Trustee, and each Affiliate of the Indenture Trustee, may buy, sell, lend upon, become a pledgee of and deal in the Debentures and generally contract and enter into financial transactions with the Corporation and any Affiliate of the Corporation without being liable to account for any profits made thereby.

12.8

Conditions Precedent to Indenture Trustee’s Obligation to Act

	(a)		The Indenture Trustee shall not be bound to give any notice, or to do, observe or perform or see to the observance or performance by the Corporation of any of the obligations imposed under the Indenture or to supervise or interfere with any of the activities of the Corporation, or to do or take any act, action or Proceeding by virtue of the powers conferred on it by this Indenture, unless and until it shall have been required to do so under the terms of this Indenture; nor shall the Indenture Trustee be required to take notice of any default or Event of Default, other than in payment of any moneys required by this Indenture to be paid to the Indenture Trustee, unless and until notified in writing of such default or Event of Default by the Corporation or by any Holder, which notice shall distinctly specify default or Event of Default, and in the absence of any such notice the Indenture Trustee may conclusively assume that no default or Event of Default has occurred. Any such notice or requisition shall in no way limit any discretion given to the Indenture Trustee in this Indenture to determine whether or not to take action with respect to any default or Event of Default or with respect to any such requisition.
	(b)		The obligation of the Indenture Trustee to do any of the actions referred to in section 12.8(a), including to commence or to continue any Proceeding or any right of the Indenture Trustee or the Holders, shall be conditional upon the Holders furnishing, when required by notice in writing by the Indenture Trustee, sufficient funds to commence or continue such action and an indemnity satisfactory to the Indenture Trustee to protect and hold harmless the Indenture Trustee against the costs, charges, expenses and liabilities which may result from such action and any loss and damage the Indenture Trustee may suffer by reason of such action.
	(c)		Before commencing or at any time during the continuance of any Proceeding, the Indenture Trustee may require the Holders on whose behalf it is acting to deposit with the Indenture Trustee the Debentures held by them, and the Indenture Trustee shall issue receipts for such Debentures.

12.9

Indenture Trustee Not Required to Give Security

The Indenture Trustee shall not be required to give Security for its conduct or administration under this Indenture.

12.10

Resignation or Removal of Indenture Trustee; Conflict of Interest

	(a)		The Indenture Trustee represents and warrants to the Corporation that at the time of the execution and delivery of this Indenture no material conflict of interest exists with respect to the Indenture Trustee’s role as a fiduciary hereunder.
	(b)		The Indenture Trustee may resign as trustee hereunder by giving not less than 60 days notice in writing to the Corporation or such shorter notice as the Corporation may accept as sufficient. The Indenture Trustee shall resign if a material conflict of interest arises with respect to its role as trustee under this Indenture that is not eliminated within 90 days after the Indenture Trustee becomes aware of such conflict of interest. Immediately after the Indenture Trustee becomes aware that it has a material conflict of interest it shall provide the Corporation with written notice of the nature of that conflict. Upon any such resignation, the Indenture Trustee shall be discharged from all further duties and liabilities under this Indenture. None of the validity and enforceability of this Indenture or the Debentures shall be affected in any manner whatsoever by reason only of the existence of a material conflict of interest on the part of the Indenture Trustee (whether arising prior to or after the date of this Indenture). If the Indenture Trustee does not comply with this section, any Holder or the Corporation may apply to the Ontario Superior Court of Justice in the judicial district of Toronto for an order that the Indenture Trustee be replaced as trustee under this Indenture.
	(c)		In the event of the Indenture Trustee resigning or being removed by the Holders by Extraordinary Resolution or by the Corporation or being dissolved, becoming insolvent or bankrupt, going into liquidation or otherwise becoming incapable of acting as trustee under this Indenture, the Corporation shall immediately appoint a successor Indenture Trustee unless a successor Indenture Trustee has already been appointed by the Holders; failing such appointment by the Corporation, the retiring Indenture Trustee or any other Holder may apply to a judge of the Ontario Superior Court of Justice in the judicial district of Toronto, on such notice as such judge may direct, for the appointment of a successor Indenture Trustee. The successor Indenture Trustee so appointed by the Corporation or by such court shall be subject to removal by the Holders by way of an Act of Holders. Any successor Indenture Trustee appointed under any provision of this section shall be a corporation authorized to carry on the business of a trust corporation in Canada or the Province of Ontario. On any appointment of the successor Indenture Trustee, the successor Indenture Trustee shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named in this Indenture as Indenture Trustee. The expenses of all acts, documents and Proceedings required under this section will be paid by the Corporation in the same manner as if the amount thereof were fees payable to the Indenture Trustee under this Indenture.
	(d)		Any successor Indenture Trustee shall, immediately upon appointment, become vested with all the estates, properties, rights, powers and trusts of its predecessor in the trusts under this Indenture, with like effect as if originally named as Indenture Trustee hereunder. Nevertheless, upon the written request of the successor Indenture Trustee or of the Corporation and upon payment of all outstanding fees and expenses, including those owed to the Indenture Trustee ceasing to act, the Indenture Trustee ceasing to act

shall execute and deliver a document assigning and transferring to such successor Indenture Trustee, upon the trusts expressed in this Indenture, all the rights, powers and trusts of the Indenture Trustee so ceasing to act, and shall duly assign, transfer and deliver all property (including money) held by such Indenture Trustee to the successor Indenture Trustee in its place. Should any deed, conveyance or other document in writing from the Corporation be required by any successor Indenture Trustee for more fully and certainly vesting in and confirming to it such estates, properties, rights, powers and trusts, then any and all such deeds, conveyances and other documents in writing shall, on the request of the successor Indenture Trustee, be made, executed, acknowledged and delivered by the Corporation.

(e)

Any corporation into which the Indenture Trustee is amalgamated or with which it is consolidated or to which all or substantially all of its corporate trust business is sold or is otherwise transferred or any corporation resulting from any consolidation or amalgamation to which the Indenture Trustee is a party shall be a successor Indenture Trustee under this Indenture, without the execution of any document or any further act; provided that such successor Indenture Trustee is a corporation qualified to carry on the business of a trust corporation in Canada or the Province of Ontario and shall not have a material conflict of interest in its role as a fiduciary under this Indenture.

12.11

Authority to Carry on Business; Resignation

The Indenture Trustee represents and warrants to the Corporation that at the date of execution and delivery by it of this Indenture it is authorized to carry on the business of a trust corporation in Canada. If the Indenture Trustee ceases to be so authorized to carry on business, the validity and enforceability of this Indenture and the Debentures issued hereunder shall not be affected in any manner by reason only of such event but the Indenture Trustee shall, within 90 days after ceasing to be authorized to carry on the business of a trust corporation in Canada, either become so authorized or resign in the manner and with the effect specified in section 12.10.

12.12

Protection of Indenture Trustee

Registered Holder: l

[For the purposes of a Global Debenture only:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF CDS CLEARING AND DEPOSITORY SERVICES INC. (“CDS”) TO STUDENT TRANSPORTATION INC. (THE “ISSUER”) OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IN RESPECT THEREOF IS REGISTERED IN THE NAME OF CDS & CO., OR TO SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CDS (AND ANY PAYMENT IS MADE TO CDS & CO.

Student Transportation Inc. (the “Corporation”), for value received, hereby acknowledges itself indebted and promises to pay to the order of the registered holder on June 30, 2018 (the “Maturity Date”), or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture hereinafter mentioned, the principal sum of

[insert amount]

in lawful money of the United States, on presentation and surrender of this Debenture at the principal office of the Indenture Trustee (as defined below) in the manner specified in the Indenture (as defined below), in the City of Toronto, Province of Ontario, and to pay interest on the principal amount hereof at the rate of 6.25% per annum from the Issue Date or from the most recent Interest Payment Date (as defined below) to which interest has been paid or made available for payment on the Debentures then

outstanding, whichever is later, in like money in equal semi-annual instalments in arrears on June 30 and December 31 in each year (each such date an “Interest Payment Date”), commencing December 31, 2011 with overdue interest, if any, at the same rate after as well as before maturity and after as well as before default in payment of principal or interest. The December 31, 2011 interest payment will represent accrued interest from the date of issue to but excluding December 31, 2011.

As interest on this Debenture becomes due, the Corporation (subject to early redemption, repurchase or conversion pursuant to the terms of the Indenture (as defined below)) shall forward or cause to be forwarded by courier or ordinary post to the registered address of the registered Holder of the Debenture for the time being, or in the case of joint Holders to the registered address of one of such joint Holders, or in accordance with the procedures established by CDS if this is a Book-Entry Only Debenture, a cheque or electronic funds transfer for such interest, payable to the order of such Holder or Holders. The forwarding of such cheque or electronic funds transfer shall satisfy and discharge the liability for interest on this Debenture to the extent of the sum represented thereby, unless such cheque, if any, be not paid on presentation.

This Debenture is one of the 6.25% Convertible Subordinated Unsecured Debentures due June 30, 2018 (the “Debentures”) in the aggregate principal amount of up to $60,000,000.00 in lawful money of the United States created and issued under a Trust Indenture (the “Indenture”) dated as of June 7, 2011 made between the Corporation and Computershare Trust Company of Canada, as trustee (the “Indenture Trustee”). Reference is hereby made to the Indenture for a description of the rights of the Holders of the Debentures, the Corporation and the Indenture Trustee and of the terms and conditions upon which the Debentures are issued and held, all to the same effect as if the provisions of the Indenture were herein set forth, to all of which provisions the Holder of this Debenture, by acceptance hereof, agrees. To the extent that the terms and conditions stated in this Debenture conflict with the terms and conditions of the Indenture, the latter shall prevail. All capitalized terms used herein have the meaning ascribed thereto in the Indenture unless otherwise indicated.

The Debentures are issuable as fully registered Debentures in denominations of US$1,000 and integral multiples of US$1,000. The Debentures of any authorized denomination may be exchanged, as provided in the Indenture, for Debentures in equal aggregate principal amount.

This Debenture and all other Debentures certified and issued under the Indenture rank pari passu with one another, in accordance to their tenor without discrimination, preference or priority and with all other present and future subordinated and unsecured Indebtedness of the Corporation. The payment of the principal and, if an event of default has occurred and is continuing under any Senior Indebtedness, interest on the Debentures is subordinated in the right of payment to the prior payment in full of all Senior Indebtedness. The Indenture does not contain any financial covenants or restrictions on the Corporation’s ability to pay Dividends Paid in the Ordinary Course, Incur Senior Indebtedness or issue or repurchase securities.

Subject to receiving all applicable regulatory approvals, the Corporation has the right, upon not less than 40 days and not more than 60 days prior notice, to elect to satisfy its obligations to repay the principal amount of the outstanding Debentures at Maturity or upon redemption for any reason (except in the event of a Change of Control) by issuing and delivering, for each US$1,000 principal amount of Debentures, that number of Freely Tradeable Common Shares equal to the number obtained by dividing such principal amount of Debentures by 95% of the Current Market Price of the Common Shares on the Maturity Date or the Redemption Date (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the Maturity Date or the Redemption Date, as the case may be), provided, however, that no Event of Default shall have occurred and be continuing. No fractional Common Shares will be delivered to the Debentureholders upon such

share redemption, but in lieu thereof, if such a fraction shall become owing, the Corporation will make an equivalent cash payment.

Each US$1,000 principal amount of Debentures is convertible at any time and from time to time prior to the close of business on the Business Day immediately preceding Maturity, or, if called for redemption, the Business Day immediately preceding the Redemption Date or the Payment Date, at the option of the Holder, into that number of Common Shares obtained by dividing US$1,000 by the conversion price of US$9.50 per Common Share, subject to adjustment upon the occurrence of certain events specified in the Indenture. No fractional Common Shares will be delivered to the Debentureholders upon conversion, but in lieu thereof, if such a fraction shall become owing, the Corporation will make an equivalent cash payment. The accrued and unpaid interest on any Debentures so converted shall be paid in cash.

Upon the giving of notice by the Indenture Trustee of the occurrence of an Event of Default in accordance with the Indenture, the Debentures will become immediately due and payable, subject to the provisions for subordination.

Subject to the immediately following paragraph, the Debentures are not redeemable on or prior to June 30, 2014. The Corporation has the right at its option to redeem the Debentures, in whole at any time or in part from time to time, on or after July 1, 2014 and prior to June 30, 2016 and prior to the Maturity Date, on not more than 60 days and not less than 30 days prior notice, at a redemption price equal to the principal amount of the Debentures to be redeemed, plus accrued and unpaid interest thereon, if any, up to but excluding the Redemption Date (the “Redemption Amount”), provided that the Weighted Average Trading Price of the Common Shares on a Recognized Stock Exchange for the 20 Trading Days ending five Trading Days prior to the date on which the Redemption Notice is given (where applicable, converted into US Dollars using the noon rate of exchange posted by the Bank of Canada on the Business Day immediately preceding the date on which the Redemption Notice is given) is at least 125% of the Conversion Price. On or after June 30, 2016 and prior to the Maturity Date, the Corporation shall have the right at its option to redeem the Debentures, in whole at any time or in part from time to time, on not more than 60 days and not less than 30 days prior notice to the Holders, at a redemption price equal to the Redemption Amount.

The Corporation must commence, within 30 days of the occurrence of a Change of Control, an Offer to Purchase for all Debentures then Outstanding. The Offer to Purchase shall be made at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to but excluding the Payment Date. The Corporation shall be required to accept for purchase and pay for all Debentures properly tendered on the Payment Date.

In the event of a Change of Control in which 10% or more of the consideration for the Common Shares in the transaction or transactions constituting a Change of Control consists of: (i) cash, (ii) trust units, limited partnership units or other participating securities of a trust, limited partnership or similar entity; (iii) equity securities that are not traded or intended to be traded immediately following such transactions on a stock exchange; or (iv) other property that is not traded or intended to be traded immediately following such transactions on a stock exchange (a “Cash Change of Control”), then, subject to regulatory approvals, during the period beginning ten trading days before the anticipated date on which the Change of Control becomes effective (the “Effective Date”) and ending 30 days after the Offer to Purchase is delivered, Debentureholders will be entitled to convert their Debentures at a new conversion price (the “Change of Control Conversion Price”) calculated as follows:

CCOCCP = OCP/(1+(CP x (c/t))) where:

CCOCCP is the Cash Change of Control Conversion Price;

OCP = is the Conversion Price in effect on the Effective Date;

CP = 39.4%;

c = the number of days from and including the Effective Date to but excluding the Maturity Date; and

t = the number of days from and including the date hereof to but excluding the Maturity Date.

In the event that the Cash Change of Control Conversion Price calculated in accordance with the formula above is less than any regulatory permitted discount to market price, the Cash Change of Control Conversion Price shall be deemed to be that implied by the maximum permitted discount to market price.

Any payments made by or on behalf of the Corporation under or with respect to the Debentures will be made free and clear of and without withholding or deduction for or on account of any Taxes, unless the Corporation or any other payor is required to withhold or deduct Taxes by Applicable Law or by the interpretation or administration thereof by the relevant Governmental Authority. If the Corporation is so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Debentures, the Corporation will cause the Indenture Trustee to make such withholding or deduction and will remit the full amount withheld or deducted to the relevant Governmental Authority as and when required by Applicable Law and the Corporation will pay such Additional Amounts as may be necessary so that the net amount received (including Additional Amounts) by each Holder (other than an Excluded Holder) after such withholding or deduction (including any withholding or deduction required to be made in respect of any Additional Amounts) will not be less than the amount such Holder would have received if such Taxes had not been withheld or deducted; provided, however, that no Additional Amounts will be payable with respect to any payment to an Excluded Holder.

Subject to receiving applicable regulatory approvals, the Corporation shall have the right to elect, from time to time, to have the Indenture Trustee deliver Common Share Bid Requests to the investment banks, brokers or dealers identified by the Corporation in its absolute discretion to satisfy its Interest Obligation on each Interest Payment Date, provided that no Event of Default has occurred and is continuing. Upon such election by the Corporation, the Indenture Trustee shall have the power to (i) accept delivery of Common Shares from the Corporation and process the Common Shares in accordance with the Common Share Interest Payment Election Notice, (ii) consummate sales of such Common Shares, as the Corporation shall direct in its absolute discretion, through the investment banks, brokers or dealers identified by the Corporation in the Common Share Interest Payment Election Notice, (iii) settle trades of Common Shares in the open market on a Recognized Stock Exchange, (iv) invest the proceeds of such sales on the direction of the Corporation in Canadian Government Obligations which mature prior to an applicable Interest Payment Date and/or use such proceeds to satisfy the Interest Obligation in whole or in part in respect of which the Common Share Interest Payment Election was made and (v) perform any other action necessarily incidental thereto. The amount received by a Holder in respect of the Interest Obligation will not be affected by whether or not the Corporation elects to satisfy the Interest Obligation pursuant to a Common Share Interest Payment Election.

The Indenture contains provisions for the holding of meetings of Debentureholders and rendering certain resolutions passed at such meetings by, or by instruments in writing signed by, the Holders of the majority in aggregate principal amount of the Debentures Outstanding binding upon all Debentureholders, subject to the provisions of the Indenture.

This Debenture may only be transferred upon compliance with the conditions precedent in the Indenture on the register kept at the principal office of the Indenture Trustee and at such other place or places, if

any, and/or by such other registrar or registrars, if any, as the Corporation with the approval of the Indenture Trustee may designate, and may be exchanged at any such place, by the Holder hereof or his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Indenture Trustee, and upon compliance with such reasonable requirements as the Indenture Trustee and/or registrar may prescribe, and such transfer shall be duly noted thereon by the Indenture Trustee or other registrar.

Neither the Debentures nor the Common Shares issuable upon conversion, redemption or Maturity of the Debentures, (collectively, the “Subject Securities”) have been or will be registered under the U.S. Securities Act of 1933, or any state securities laws of the United States. Subject to certain exceptions, none of the Subject Securities nor any rights thereto or interest therein may be offered for purchase or sale, sold, transferred or otherwise disposed of, directly or indirectly, in the United States, its territories or possessions, or to or for the account or benefit of any “U.S. person” as that term is defined in Regulation S under the U.S. Securities Act of 1933.

This Debenture shall not become obligatory for any purpose until it shall have been certified by the Indenture Trustee for the time being under the Indenture.

This Debenture shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable thereto.

The Holder of this Debenture, by receiving and holding same, hereby accepts and agrees to be bound by the terms, and to be entitled to the benefits of this Debenture and of the Indenture and confirms the appointment of the Indenture Trustee and of the Indenture, the whole in accordance with and subject to the respective provisions thereof.
