Exchange.

(a) Conditions and Number of Class A Shares. At any time prior to (i) the close of business on July 2, 2012 (ii) the delivery to the Company of a Retraction Notice, or (iii) the delivery to the Holder of a Regulatory Call Notice (as defined in the Stakeholders Agreement), the Holder may, at the Holder's option, exchange the principal amount of this Exchangeable Debenture (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) for Class A Shares at the Exchange Price then in effect. The number of Class A Shares issuable upon exchange of the Exchangeable Debenture shall be determined by dividing the principal amount of the Exchangeable Debenture or portion thereof, including any accrued but unpaid interest thereon, surrendered for exchange by the Exchange Price in effect on the Exchange Date. The initial Exchange Pric e is $23.20 per Class A Share subject to adjustment as provided in this Section 5.

(b) Additional Class A Shares. If, on either the Put Date or the Maturity Date, the Holder has surrendered all or any portion of his Exchangeable Debenture for exchange and has sold the Class A Shares received upon exchange pursuant to an underwritten public offering within 120 days of such surrender ("Secondary Sale") and receives aggregate gross proceeds (after giving effect to underwriting discounts and commissions which shall be paid by the Company and shall not reduce the number of Class A Shares to be received by the Holder) less than the amount determined by multiplying the number of shares sold by the Average Market Value of the shares, then Parent shall, as soon as reasonably practicable following receipt of a notice (the "Additional Share Notice") stating the exercise of the Holder's rights pursuant to this Section 5(b), issue an additional number of Class A Shares to the Holder. The payment of the fees and expenses associated with such Secondary Sale (other than with respect to underwriting discounts and commissions) shall be as set forth in the Registration Rights Agreement. It shall be a condition of such issuance that the Additional Share Notice shall include a representation and warranty of the Holder that it is an accredited investor within the meaning of the Securities Act (Ontario) and is acquiring such additional Class A Shares as principal.

592229.04-New York Server 6A - MSW

The number of such shares to be issued shall equal the amount of such difference divided by the last reported sales price of the of the Class A Shares on the NYSE on the closing date of the Secondary Sale, provided, however, that the number of shares to be so issued pursuant to this Section 5(b) shall not exceed an amount equal to 3% of the number of Class A Shares issuable upon exchange of all Exchangeable Debentures and Second Exchangeable Debentures then outstanding times a fraction, the numerator of which is the number of Class A Shares sold in the underwritten offering and the denominator of which is the number of Class A Shares issuable upon exchange of the entire principal amount of all Exchangeable Debentures and Second Exchangeable Debentures. The Company acknowledges that the Holder may surrender the Exchangeable Debenture at the closing of the Secondary Sale and may withdraw its obligation to surrender the Exchangeable Debenture in the event that the Secondary Sale does not close. In the event that the Holder surrenders the Exchangeable Debenture, interest will no longer accrue on such Exchangeable Debenture from and after the date of surrender, unless the Holder subsequently withdraws such surrender if the Secondary Sale does not close, in which case interest will be reinstated for the period of such surrender. In no event will interest accrue after the Maturity Date.

(c) 45 Day Waiting Period. The Holder is not entitled to any rights of a holder of Class A Shares until 45 days after the Holder has exchanged its Exchangeable Debentures for Class A Shares (the "Exchange Effective Date"), and only to the extent the Exchangeable Debenture has been deemed to have been exchanged for Class A Shares pursuant to this Section 5. The person in whose name the Class A Share certificate is registered following exchange shall be deemed to be a stockholder of record on the Exchange Effective Date.

(d) Exchange Procedure. To exchange the Exchangeable Debenture, the Holder must (i) complete and manually sign the exchange notice on the back of this Exchangeable Debenture and deliver such notice to the Company, with a copy to Parent, and (ii) surrender the Exchangeable Debenture to the Company. The date on which the Holder satisfies all those requirements is the "Exchange Date." As soon as practicable after the Exchange Effective Date, Parent shall deliver to the Holder, either directly or through the Company, a certificate for the number of whole Class A Shares issuable upon the exchange and cash in lieu of any fractional shares. Any cash paid in lieu of fractional shares shall be based upon the Closing Price of the Class A Shares on the Business Day immediately prior to the Exchange Date. If this Debenture is exchanged i n part only, the Company shall execute and deliver to the Holder, a new Exchangeable Debenture equal in principal amount to the unconverted portion of the Exchangeable Debenture surrendered.

(e) Taxes on Exchange. If the Holder exchanges this Exchangeable Debenture, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Class A Shares upon such exchange. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. Nothing herein shall preclude any tax withholding imposed on or with respect to Holder required by law or regulation.

592229.04-New York Server 6A - MSW

(f) Parent To Provide Stock. Parent shall, prior to issuance of any Class A Shares hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Class A Shares, a sufficient number of Class A Shares to permit the exchange of the Exchangeable Debenture into Class A Shares. All Class A Shares delivered upon exchange of the Exchangeable Debenture shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

(g)Compliance With Securities Laws; Listing. Parent will endeavor promptly to comply with all applicable federal, state and provincial securities laws regulating the offer and delivery of Class A Shares upon exchange of Exchangeable Debenture, if any, and will list or cause to have quoted such Class A Shares on each national securities exchange, the TSX or on The Nasdaq National Market or other over-the-counter market or such other market on which the Class A Shares are then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Class A Shares until the first exchange of the Exchangeable Debenture into Class A Shares in accordance with the provisions hereof, Parent covenants to list such Class A Shares issuable upon exchange of the Exchangeable Debenture in accordance with the req uirements of such automated quotation system or exchange on or prior to the first Exchange Effective Date.

(h) Adjustment of Exchange Price. The initial exchange price as stated in Section 5(a) hereof shall be adjusted from time to time (as so adjusted, the "Exchange Price") as follows:

(i) In case Parent shall (1) pay a dividend on its Class A Shares in Class A Shares, (2) make a distribution on its Class A Shares in Class A Shares, (3) subdivide its outstanding Class A Shares into a greater number of shares, or (4) combine its outstanding Class A Shares into a smaller number of shares, the Exchange Price in effect immediately prior thereto shall be adjusted so that the Holder upon exchange of the Exchangeable Debenture shall thereafter be entitled to receive that number of Class A Shares which it would have owned had the Exchangeable Debenture been exchanged immediately prior to the happening of such event. An adjustment made pursuant to this subsection (i) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision or combi nation.

(ii) In case Parent shall, by dividend or otherwise, at any time distribute (a "Triggering Distribution") to all or substantially all holders of its Class A Shares, cash in an aggregate amount that, together with the aggregate amount of (A) any cash and the fair market value (as reasonably determined in good faith by the Board of Directors of Parent, whose determination shall be conclusive evidence thereof) of any other consideration payable to holders of Class A Shares in respect of any offer by Parent or a Subsidiary of Parent to purchase Class A Shares from Parent's Class A stockholders on a pro rata basis and such offer is consummated within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Exchange Price adjustment pursuant to this Section 5 has been made and (B) all other cash distributions to all or substantia lly all holders of its Class A Shares made within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no

592229.04-New York Server 6A - MSW

Exchange Price adjustment pursuant to this Section 5 has been made, exceeds an amount equal to 5% of the product of the Current Market Price Per Class A Share on the Business Day (the "Determination Date") immediately preceding the day on which such Triggering Distribution is declared by Parent multiplied by the number of Class A Shares outstanding on the Determination Date (excluding shares held in the treasury of Parent), the Exchange Price shall be reduced so that the same shall equal the price determined by multiplying such Exchange Price in effect immediately prior to the Determination Date by a fraction of which the numerator shall be the Current Market Price Per Class A Share on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (as reasonably determined in good faith by the Board of Directors of Pare nt, whose determination shall be conclusive evidence of such fair market value) of any such other consideration so distributed, paid or payable within such 12 months (including, without limitation, the Triggering Distribution) applicable to one Class A Share (determined on the basis of the number of Class A Shares outstanding on the Determination Date) and the denominator shall be such Current Market Price Per Class A Share on the Determination Date, such reduction to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid.

(1) In case any offer, by Parent or any of its Subsidiaries to purchase Class A Shares from Parent's Class A stockholders on a pro rata basis shall expire and such offer (as amended upon the expiration thereof) shall involve the payment of aggregate consideration in an amount (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as reasonably determined in good faith by the Board of Directors of Parent), whose determination shall be conclusive evidence thereof of any other consideration) that, together with the aggregate amount of (A) any cash and the fair market value (as reasonably determined in good faith by the Board of Directors of Parent, whose determination shall be conclusive evidence thereof) of any other consideration payable in respect of any other offers by Parent or any Subsidiary of Parent to purchase Class A Sh ares from Parent's Class A stockholders on a pro rata basis consummated within the 12 months preceding the date of the Expiration Date (as defined below) and in respect of which no Exchange Price adjustment pursuant to this Section 5 has been made and (B) all cash distributions to all or substantially all holders of its Class A Shares made within the 12 months preceding the Expiration Date and in respect of which no Exchange Price adjustment pursuant to this Section 5 has been made, exceeds an amount equal to 5% of the product of the Current Market Price Per Class A Share as of the last date (the "Expiration Date") tenders, repurchases or redemptions could have been made pursuant to such offer (as it may be amended) (the last time at which such purchases could have been made on the Expiration Date is hereinafter sometimes called the "Expiration Time") multiplied by the number of Class A Shares outstanding (including tendered shares but excluding any shares held in the treasury of Parent) at the Expiration Time, then, immediately prior to the opening of business on the day after the Expiration Date, the Exchange Price shall be reduced so that the same shall equal the price determined by multiplying the Exchange Price in effect immediately prior to the close of business on the Expiration Date by a fraction of which the numerator shall be the product of the number of Class A Shares outstanding (including tendered, repurchased or redeemed shares but excluding any shares held in the treasury of Parent) at the Expiration Time multiplied by the Current Market Price Per Class A Share on the Trading Day

592229.04-New York Server 6A - MSW

next succeeding the Expiration Date and the denominator shall be the sum of (x) the aggregate consideration (determined as aforesaid) payable to Class A stockholders based on the acceptance (up to any maximum specified in the terms of the offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of Class A Shares outstanding (less any Purchased Shares and excluding any shares held in the treasury of Parent) at the Expiration Time and the Current Market Price Per Class A Share on the Trading Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that Parent or its Subsidiary, as t he case may be, is obligated to purchase shares pursuant to any offer to purchase Class A Shares from Parent's Class A stockholders on a pro rata basis, but Parent or its Subsidiary, as the case may be, is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Exchange Price shall again be adjusted to be the Exchange Price which would have been in effect based upon the number of shares actually purchased. If the application of this Section 5(h) would result in an increase in the Exchange Price, no adjustment shall be made under this Section 5(h).

(2) For the purpose of any computation under subsections (i) and (ii) of this Section 5(h), the current market price per Class A Share (the "Current Market Price Per Share") on any date shall be deemed to be the average of the daily Closing Prices for the 30 consecutive Trading Days commencing 45 Business Days before (i) the Determination Date or the Expiration Date, as the case may be, with respect to distributions or offers under subsection (ii) of this Section 5(h) or (ii) the record date with respect to distributions, issuances or other events requiring such computation under subsection (i) of this Section 5(h). The Closing Price for each day (the "Closing Price") shall be the last reported sales price or, in case no such reported sale takes place on such date, the average of the reported closing bid and asked prices in case on the NYSE. If the Class A Shares are not then quoted or listed or admitted to trading on the NYSE, the last reported sale price referenced above shall be determined based on the last reported sale price on the TSX (and converted to U.S. dollars at the exchange rate quoted by the Bank of Canada at such time) or, if the Class A Shares are not then quoted or listed or admitted to trading on the NYSE or TSX, any national securities exchange or quotation system on which sales of Class A Shares takes place, or, in case no reported sale takes place, the Market Price shall be the fair value of a Class A Shares as reasonably determined in good faith by the Board of Directors of the Company.

(3) In any case in which this Section 5(h) shall require that an adjustment be made following a record date or a Determination Date or Expiration Date, as the case may be, established for purposes of this Section 5(h), Parent may elect to defer issuing to the Holder until after such record date or Determination Date or Expiration Date the Class A Shares and other capital stock of Parent issuable upon such exchange over and above the Class A Shares and other capital stock of Parent issuable upon such exchange only on the basis of the Exchange Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, Parent shall issue or cause its transfer agent to issue due bills or other appropriate evidence prepared by Parent of the right to receive such shares. If any distribution in respect of which an adjustment to the

592229.04-New York Server 6A - MSW

Exchange Price is required to be made as of the record date or Determination Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Exchange Price shall be readjusted to the Exchange Price which would then be in effect if such record date had not been fixed or such effective date or Determination Date or Expiration Date had not occurred.

(iii) If any event occurs as to which the foregoing provisions of this Section 5(h) are not strictly applicable or, ifstrictly applicable, would not, in the good faith judgment of the Company, fairly and adequately protect the rights of the Holder in accordance with the essential intent and principles of such provisions, then the Company shall make such adjustments in the application of such provisions, in accordance with such essential intent and principles, as shall be reasonably necessary, in the good faith opinion of the Company, to protect such rights as aforesaid, but in no event shall any such adjustment have the effect of increasing the Exchange Price or decreasing the number of Class A Shares issuable upon exchange of this Exchangeable Debenture.

(iv) Adjustment for Tax Purposes.

Parent shall be entitled to make such reductions in the Exchange Price, in addition to those required by this Section 5(h), as it in its discretion shall determine to be advisable in order that any stock dividends, subdivisions of shares, distributions of rights to purchase stock or Exchangeable Debenture or distributions of Exchangeable Debenture convertible into or exchangeable for stock hereafter made by Parent to its stockholders shall not be taxable.

(v) Notice of Adjustment. Whenever the Exchange Price or exchange privilege is adjusted, Parent or Company shall promptly mail to the Holder a notice of the adjustment.

(vi) Notice of Certain Transactions.

In the event that:

(1) Parent or the Company consolidates or merges with or into, or transfers all or substantially all of its property and assets to, another corporation or another corporation merges into Parent or the Company and;

(2) a record date has been established by Parent for any distributions to holders of Class A Shares, other than a distribution comprised solely of ordinary dividends; or

(3) there is a dissolution or liquidation of Parent or the Company,

Parent shall mail to Holders a notice stating the proposed record or effective date, as the case may be. Parent shall mail the notice at least twenty days in advance of the applicable record date for such action. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2), or (3) of this Section 5(h)(vi).
