Exhibit 6

DESCRIPTION OF SUBORDINATE VOTING SHARES AND PREFERRED SHARES

The following briefly
summarizes the provisions of our articles of incorporation, including a description of our share capital. The following description may not be complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of our
articles of incorporation.

Our authorized share capital consists of an unlimited number of Multiple Voting Shares carrying ten votes per
share, an unlimited number of Subordinate Voting Shares carrying one vote per share and an unlimited number of preferred shares, issuable in series. At December 9, 2010, twelve series of preferred shares had been created and there were
outstanding 1,548,000 Multiple Voting Shares and 19,706,477 Subordinate Voting Shares, as well as 10,000,000 Series C Shares, 8,000,000 Series E Shares, 10,000,000 Series G Shares and 12,000,000 Series I shares. At December 9, 2010, 799,230
Subordinate Voting Shares were effectively held by Fairfax through a minority ownership interest in The Sixty Two Investment Company Limited (Sixty Two).

Multiple Voting Shares and Subordinate Voting Shares

Dividend Rights

Holders of Multiple Voting Shares and Subordinate Voting Shares participate equally as to dividends and are entitled to dividends, in
equal amounts per share and at the same time, that our board of directors may declare out of legally available funds, subject to the preferential dividend rights of the preferred shares.

Voting Rights

Holders of Multiple Voting Shares and Subordinate Voting Shares are
entitled to receive notice of any meeting of our shareholders and may attend and vote at such meetings, except those meetings where only the holders of shares of another class or of a particular series are entitled to vote. The Multiple Voting
Shares are entitled to ten votes per share, except as set forth below, and the Subordinate Voting Shares are entitled to one vote per share.

The ten votes per share attached to the Multiple Voting Shares are automatically and permanently reduced to one vote per share if:



| | (i) | the number of the Multiple Voting Shares held by Sixty Two (and its 75% owned subsidiaries, of which there are currently none) falls below 1,197,480 shares, unless this
results from a sale of shares to purchasers who make an equivalent unconditional offer to purchase all outstanding Subordinate Voting Shares; or
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the number of the Multiple Voting Shares held by purchasers referred to in (i) above (and their 75% owned subsidiaries) falls below 1,197,480.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------

A change of control of Sixty Two or a purchaser referred to in (i) above will disqualify that shareholders holding
of shares for the purposes of the calculations contained in (i) and (ii) above. Except in connection with a sale to a purchaser who makes an offer to purchase all outstanding Subordinate Voting Shares as contemplated by (i) above,
Sixty Two has agreed with us that it will not sell our Multiple Voting Shares (except to its 75% owned subsidiaries).

The number of votes
attached to the Multiple Voting Shares will automatically but temporarily be reduced to one vote per share for any shareholders meeting if, during the three months ending ten days prior to the date we send notice of the shareholders
meeting, the weighted average trading price in the principal trading market of the Subordinate Voting Shares for any period of thirty consecutive trading days is less than Cdn$4.00 per share (subject to adjustment).

Preemptive, Subscription, Redemption and Conversion Rights

Holders of Subordinate Voting Shares and Multiple Voting Shares have no preemptive, subscription or redemption rights. Holders of Subordinate Voting Shares have no conversion rights. Multiple Voting
Shares are convertible at any time into Subordinate Voting Shares on the basis of one Subordinate Voting Share for each Multiple Voting Share being converted.



---

Liquidation Rights

Upon our liquidation, dissolution or winding up, whether voluntary or involuntary, the holders of the Subordinate Voting Shares and Multiple Voting Shares, without preference or distinction, are entitled
to receive ratably all of our assets remaining after payment of all debts and other liabilities, subject to the prior rights of holders of any outstanding preferred shares and any other prior ranking shares.

Modifications

Modifications to
the provisions attaching to the Multiple Voting Shares as a class, or to the Subordinate Voting Shares as a class, require the separate affirmative vote of two-thirds of the votes cast at meetings of the holders of the shares of each class.

No subdivision or consolidation of the Multiple Voting Shares or of the Subordinate Voting Shares may take place unless the shares of both
classes are subdivided or consolidated at the same time in the same manner and proportion.

No rights to acquire additional shares or other
securities or property of ours will be issued to holders of Multiple Voting Shares or Subordinate Voting Shares unless the same rights are issued at the same time to holders of shares of both classes.

Preferred Shares

As you read this
section, please remember that the specific terms of your series of preferred shares as described in your prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section. If there are
differences between your prospectus supplement and this prospectus, your prospectus supplement will control. Thus, the statements we make in this section may not apply to your series of preferred shares.

Reference to a series of preferred shares means all of the preferred shares issued as part of the same series and having the attributes set out in
articles of amendment. Reference to your prospectus supplement means the prospectus supplement describing the specific terms of the preferred shares you purchase. The terms in your prospectus supplement will have the meanings described in this
prospectus, unless otherwise specified.

We have delivered an undertaking to the securities regulatory authority in each of the provinces of
Canada that we will not distribute exchangeable preferred shares, other than preferred shares exchangeable for securities of one of our affiliates, separately to any member of the public in Canada unless the offering is in connection with and forms
part of the consideration for an acquisition or merger transaction or unless the prospectus supplement containing the specific terms of the exchangeable preferred shares to be distributed separately is first approved for filing by the securities
commissions or similar regulatory authorities in each of the provinces and territories of Canada where the exchangeable preferred shares will be distributed.

Our Authorized Preferred Shares

Under our articles of incorporation, our board of
directors is authorized, subject to Canadian law, without shareholder approval, from time to time to issue an unlimited number of preferred shares in one or more series. Our board of directors can fix the rights, privileges, restrictions and
conditions of the shares of each series. Preferred shares are entitled to priority over our Subordinate Voting Shares and Multiple Voting Shares as to dividends and distributions of assets upon our liquidation, dissolution or winding-up. Preferred
shares may be convertible into shares of any other series or class of shares if our board of directors so determines. Our board of directors will fix the terms of the series of preferred shares it designates by resolution and will file articles of
amendment as required under Canadian law before we issue any shares of the series of preferred shares.



---

The prospectus supplement relating to the particular series of preferred shares will contain a description
of the specific terms of that series as fixed by our board of directors, including, as applicable;



| |  |  | the offering price at which we will issue the preferred shares;
| | - |  | ---------------------------------------------------------------



| |  |  | the title and designation of number of shares of the series of preferred shares;
| | - |  | --------------------------------------------------------------------------------



| |  |  | the dividend rate or method of calculation, the payment dates for dividends and the place or places where the dividends will be paid, whether
dividends will be cumulative or noncumulative, and, if cumulative, the dates from which dividends will begin to accumulate;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any conversion or exchange rights;
| | - |  | ----------------------------------



| |  |  | whether the preferred shares will be subject to redemption and the redemption price and other terms and conditions relative to the redemption
rights;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any liquidation rights;
| | - |  | -----------------------



| |  |  | any sinking fund provisions;
| | - |  | ----------------------------



| |  |  | any voting rights; and
| | - |  | ----------------------



| |  |  | any other rights, preferences, privileges, limitations and restrictions that are not inconsistent with the terms of our articles of
incorporation.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

The preferred shares of each series shall rank on a parity with the preferred shares of every other series
with respect to dividends and return of capital in the event of the liquidation, dissolution or winding-up, and will be entitled to a preference over our Subordinate Voting Shares and Multiple Voting Shares and over any other shares ranking junior
to the preferred shares with respect to priority in payment of dividends and in the distribution of assets in the event of our liquidation, dissolution or winding-up, whether voluntary or involuntary, or any other distribution of our assets among
shareholders for the purpose of winding-up our affairs. If any cumulative dividends, whether or not declared, or declared non-cumulative dividends or amounts payable on a return of capital in the event of the liquidation, dissolution or winding-up
are not paid in full in respect of any series of the preferred shares, the preferred shares of all series will participate ratably in respect of such dividends in accordance with the sums that would be payable on such shares if all such dividends
were declared and paid in full, and in respect of such return of capital in accordance with the sums that would be payable on such return of capital if all sums so payable were paid in full; provided, however, that if there are insufficient assets
to satisfy in full all such claims, the claims of the holders of the preferred shares with respect to return of capital will be paid and satisfied first and any assets remaining thereafter will be applied towards the payment and satisfaction of
claims in respect of dividends. The preferred shares of any series may also be given such other preferences not inconsistent with the rights, privileges, restrictions and conditions attached to the preferred shares as a class over our Subordinate
Voting Shares and Multiple Voting Shares and over any other shares ranking junior to the preferred shares as may be determined in the case of such series of preferred shares.

Voting Rights

The prior approval of not less than two-thirds of the votes cast at a
meeting of holders of Subordinate Voting Shares is required before we may create any class or series of shares that have voting rights (except as required by law or allowed if dividends are in arrears).

The holders of our preferred shares, Series C through Series J, are not (except as otherwise provided by law and except for meetings of the holders of a
particular series) entitled to receive notice of, attend, or vote at, any meeting of our shareholders unless and until we have failed to pay eight quarterly dividends on such series of preferred shares, whether or not consecutive and whether or not
such dividends have been declared and whether or not there are any monies of the Company properly applicable to the payment of dividends. In the event of such non-payment, and for only so long as any such dividends remain in arrears, the holders of
such series of preferred shares will be entitled to receive notice of and to attend each meeting of our shareholders at which directors are to be elected and to one vote for each share of such series held. Upon payment of the entire amount of all
dividends in arrears in respect to such series of preferred shares, the voting rights of the holders of such series shall forthwith cease.



---

Amendment with Approval of Holders of the Preferred Shares

The rights, privileges, restrictions and conditions attached to the preferred shares as a class may be added to, changed or removed but only with the
approval of the holders of the preferred shares. The approval of the holders of the preferred shares to add to, change or remove any right, privilege, restriction or condition attaching to the preferred shares as a class or in respect of any other
matter requiring the consent of the holders of the preferred shares may be given in such manner as may then be required by Canadian law, subject to a minimum requirement that such approval be given by resolution signed by all the holders of the
preferred shares or passed by the affirmative vote of at least 2/3 of the votes cast at a meeting of the holders of the preferred shares duly called for that purpose.

The formalities to be observed with respect to the giving of notice of any such meeting or any adjourned meeting, the quorum required therefore and the conduct thereof will be those from time to time
prescribed by our by-laws with respect to meetings of shareholders, or if not so prescribed, as required by Canadian law as in force at the time of the meeting. On every poll taken at every meeting of the holders of the preferred shares as a class,
or at any joint meeting of the holders of two or more series of preferred shares, each holder of preferred shares entitled to vote at such meeting will have one vote in respect of each preference share held.

Redemption

If so specified in
the applicable prospectus supplement, a series of preferred shares may be redeemable at any time, in whole or in part, at our option or the holders, or may be subject to mandatory redemption.

Any restriction on the repurchase or redemption by us of our preferred shares while we are in arrears in the payment of dividends will be described in
the applicable prospectus supplement.

Any partial redemptions of preferred shares will be made in a way that our board of directors decides
is equitable.

Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of
preferred shares called for redemption and all rights of holders of these shares will terminate except for the right to receive the redemption price.

Dividends

Holders of each series of preferred shares will be entitled to receive
dividends when, as and if declared by our board of directors from funds legally available for payment of dividends. The rates and dates of payment of dividends will be set forth in the applicable prospectus supplement relating to each series of
preferred shares.

Dividends will be payable to holders of record of preferred shares as they appear on our books on the record dates fixed by
the board of directors. Dividends on any series of preferred shares may be cumulative or noncumulative, as set forth in the applicable prospectus supplement.

Conversion or Exchange Rights

The prospectus supplement relating to any series of
preferred shares that is convertible or exchangeable will state the terms on which shares of that series are convertible into or exchangeable for Subordinate Voting Shares, another series of our preferred shares or any other securities offered
pursuant to this prospectus.

Transfer Agent and Registrar

The transfer agent, registrar and dividend disbursement agent for the preferred shares will be stated in the applicable prospectus supplement. The registrar for shares of preferred shares will send notice
to shareholders of any meetings at which holders of the preferred shares have the right to vote on any matter.

Description of the Series C Shares

The following is a summary of certain provisions attaching to the Series C Shares as a series.

Definition of Terms

The following definitions are relevant to the Series C Shares.

Annual Fixed Dividend Rate means, for any Subsequent Fixed Rate Period, the annual rate (expressed as a percentage
rate rounded down to the nearest one hundred-thousandth of one percent (with 0.000005% being rounded up)) equal to the sum of the Government of Canada Yield on the applicable Fixed Rate Calculation Date plus 3.15%.

Bloomberg Screen GCAN5YR Page means the display designated as page GCAN5YR<INDEX> on the Bloomberg Financial
L.P. service (or such other page as may replace the GCAN5YR page on that service) for purposes of displaying Government of Canada bond yields.

Fixed Rate Calculation Date means, for any Subsequent Fixed Rate Period, the 30th day prior to the first day of such Subsequent
Fixed Rate Period.

Government of Canada Yield on any date means the yield to maturity on such date (assuming
semi-annual compounding) of a Canadian dollar denominated non-callable Government of Canada bond with a term to maturity of five years as quoted as of 10:00 a.m. (Toronto time) on such date and which appears on the Bloomberg Screen GCAN5YR Page on
such date; provided that, if such rate does not appear on the Bloomberg Screen GCAN5YR Page on such date, the Government of Canada Yield will mean the average of the yields determined by two registered Canadian investment dealers selected by the
Company, as being the yield to maturity on such date (assuming semi-annual compounding) which a Canadian dollar denominated non-callable Government of Canada bond would carry if issued in Canadian dollars at 100% of its principal amount on such date
with a term to maturity of five years.

Initial Fixed Rate Period means the period commencing on the Closing Date
and ending on and including December 31, 2014.

Subsequent Fixed Rate Period means for the initial Subsequent
Fixed Rate Period, the period commencing on January 1, 2015 and ending on and including December 31, 2019 and for each succeeding Subsequent Fixed Rate Period, the period commencing on the day immediately following the end of the

Price

The Series C Shares will have an issue price of Cdn$25.00 per share.

Dividends

During the Initial Fixed Rate Period, the holders of the Series C Shares
will be entitled to receive fixed cumulative preferential cash dividends, as and when declared by the Board of Directors, payable quarterly on the last business day of March, June, September and December in each year during the Initial Fixed Rate
Period, at an annual rate equal to Cdn$1.43750 per share. The initial dividend, if declared, will be payable December 31, 2009 and will be Cdn$0.34362 per share (less any tax required to be deducted and withheld by the Company), based on the
anticipated closing date of October 5, 2009.

During each Subsequent Fixed Rate Period, the holders of Series C Shares will be entitled
to receive fixed cumulative preferential cash dividends, as and when declared by the Board of Directors, payable quarterly on the last business day of March, June, September and December in each year during the Subsequent Fixed Rate Period, in an
annual amount per share determined by multiplying the Annual Fixed Dividend Rate applicable to such Subsequent Fixed Rate Period by Cdn$25.00 (less any tax required to be deducted and withheld by the Company).

The Annual Fixed Dividend Rate applicable to a Subsequent Fixed Rate Period will be determined by the Company on the Fixed Rate Calculation Date. Such
determination will, in the absence of manifest error, be final and binding upon the Company and upon all holders of Series C Shares. The Company will, on the Fixed Rate Calculation Date, give written notice of the Annual Fixed Dividend Rate for the
ensuing Subsequent Fixed Rate Period to the registered holders of the then outstanding Series C Shares.

accrue on a daily basis. If, on any dividend payment date, the dividends accrued to such date are not paid in full on all of the Series C Shares then outstanding, such dividends, or the unpaid portion thereof, will be paid on a subsequent date or
dates determined by the Board of Directors on which the Company will have sufficient funds properly applicable to the payment of such dividends.

Redemption

The Series C Shares will not be redeemable by the Company prior to December 31, 2014. On December 31, 2014 and on December 31 every five years thereafter, and subject to certain other
restrictions set out in Restrictions on Dividends and Retirement and Issue of Shares below, the Company may, at its option, on at least 30 days and not more than 60 days prior written notice, redeem all or from time to time any part of
the outstanding Series C Shares by payment in cash of a per share sum equal to Cdn$25.00, in each case plus an amount equal to an amount equal to the sum (the Accrued Amount) of (i) all unpaid dividends (whether or not
declared) in respect of completed quarters preceding up to but excluding the date fixed for redemption; and (ii) an amount equal to the cash dividend in respect of the quarter in which the redemption occurs pro rated to such date (less any tax
required to be deducted and withheld by the Company).

If less than all of the outstanding Series C Shares are to be redeemed, the shares to
be redeemed shall be selected on a pro rata basis disregarding fractions or, if such shares are at such time listed on an exchange, with the consent of such exchange, in such manner as the Board of Directors in its sole discretion may, by
resolution, determine.

The Series C Shares do not have a fixed maturity date and are not redeemable at the option of the holders of Series C
Shares. See Risk Factors.

Conversion of Series C Shares into Series D Shares

Holders of Series C Shares will have the right, at their option, on December 31, 2014 and on December 31st every five years thereafter (each, a
Series C Conversion Date), to convert, subject to applicable law and the restrictions on conversion described below and the payment or delivery to the Company of evidence of payment of the tax (if any) payable, all or any of their
Series C Shares registered in their name into Series D Shares on the basis of one Series D Share for each Series C Share. If a Series C Conversion Date would otherwise fall on a day that is not a business day, such Series C Conversion Date shall be
the immediately following business day. The conversion of Series C Shares may be effected upon notice given by the registered holders of the Series C Shares not earlier than the 30th day prior to, but not later than 5:00 p.m. (Toronto time) on the
15th day preceding, a Series C Conversion Date. Once received by the Company, an election notice is irrevocable.

The Company will, at least
30 days and not more than 60 days prior to the applicable Series C Conversion Date, give notice in writing to the then registered holders of Series C Shares of the above-mentioned conversion right. On the 30th day prior to each Series C Conversion
Date, the Company will give notice in writing to the then registered holders of the Series C Shares of the Annual Fixed Dividend Rate for the next succeeding Subsequent Fixed Rate Period and the Floating Quarterly Dividend Rate (as defined below)
applicable to the Series D Shares for the next succeeding Quarterly Floating Rate Period.

If the Company gives notice to the registered
holders of the Series C Shares of the redemption on a Series C Conversion Date of all the Series C Shares, the Company will not be required to give notice as provided hereunder to the registered holders of the Series C Shares of an Annual Fixed
Dividend Rate, a Floating Quarterly Dividend Rate or of the conversion right of holders of Series C Shares and the right of any holder of Series C Shares to convert such Series C Shares will cease and terminate in that event.

Holders of Series C Shares will not be entitled to convert their shares into Series D Shares if the Company determines that there would remain
outstanding on a Series C Conversion Date less than 1,000,000 Series D Shares, after having taken into account all Series C Shares tendered for conversion into Series D Shares and all Series D Shares tendered for conversion into Series C Shares. The
Company will give notice in writing to all registered holders of Series C Shares of their inability to convert their Series C Shares at least seven days prior to the applicable Series C Conversion Date. Furthermore, if the Company determines that
there would remain outstanding on a Series C Conversion Date less than 1,000,000 Series C Shares, after having taken into account all Series C Shares tendered for conversion into Series D Shares and all Series D Shares tendered for conversion into
Series C Shares, then, all, but not part, of the remaining outstanding Series C Shares will automatically be converted into Series D Shares on the basis of one Series D Share for each Series C Share, on the applicable Series C Conversion Date and
the Company will give notice in writing to this effect to the then registered holders of such remaining Series C Shares at least seven days prior to the Series C Conversion Date.

Upon exercise by a registered holder of its right to convert Series C Shares into Series D Shares (and upon an automatic conversion), the Company reserves the right not to deliver Series D Shares to any
person whose address is in, or whom the Company or its transfer agent has reason to believe is a resident of, any jurisdiction outside Canada, to the extent that such issue would require the Company to take any action to comply with the securities
or analogous laws of such jurisdiction.

Purchase for Cancellation

Subject to applicable law and to the provisions described under Restrictions on Dividends and Retirement and Issue of Shares below, the Company may at any time purchase for cancellation the
whole or any part of the Series C Shares at the lowest price or prices at which, in the opinion of the Board of Directors, such shares are obtainable.

Rights on Liquidation

In the event of the liquidation, dissolution or winding-up of the Company or any other distribution of assets of the Company among its shareholders for the purpose of winding-up its affairs, the holders
of the Series C Shares will be entitled to receive Cdn$25.00 per share, together with all accrued and unpaid dividends (whether or not declared) up to but excluding the date of payment or distribution (less any tax required to be deducted or
withheld by the Company), before any amount is paid or any assets of the Company are distributed to the holders of the Companys multiple voting shares, subordinate voting shares and any other shares ranking junior as to capital to the Series C
Shares. Upon payment of such amounts, the holders of the Series C Shares will not be entitled to share in any further distribution of the assets of the Company.

Priority

The Series C Shares shall rank on a parity with the preferred shares of
every other series with respect to dividends and distribution of assets in the event of the liquidation, dissolution or winding-up, and will be entitled to a preference over the Companys subordinate voting shares and multiple voting shares and
over any other shares ranking junior to the preferred shares with respect to priority in payment of dividends and in the distribution of assets in the event of the Companys liquidation, dissolution or winding-up, whether voluntary or
involuntary, or any other distribution of the Companys assets among shareholders for the purpose of winding-up its affairs. If any cumulative dividends, whether or not declared, or declared non-cumulative dividends or amounts payable on a
return of capital in the event of the liquidation, dissolution or winding-up are not paid in full in respect of any series of the preferred shares, the preferred shares of all series will participate ratably in respect of such dividends in
accordance with the sums that would be payable on such shares if all such dividends were declared and paid in full, and in respect of such return of capital in accordance with the sums that would be payable on such return of capital if all sums so
payable were paid in full; provided, however, that if there are insufficient assets to satisfy in full all such claims, the claims of the holders of the preferred shares with respect to return of capital will be paid and satisfied first and any
assets remaining thereafter will be applied towards the payment and satisfaction of claims in respect of dividends.

Restrictions on
Dividends and Retirement and Issue of Shares

So long as any of the Series C Shares are outstanding, the Company will not, without the
approval of the holders of the Series C Shares:

(a) declare, pay or set apart for payment any dividends (other than stock dividends payable
in shares of the Company ranking as to capital and dividends junior to the Series C Shares) on shares of the Company ranking as to dividends junior to the Series C Shares;

(b) except out of the net cash proceeds of a substantially concurrent issue of shares of the Company ranking as to return of capital and dividends junior to the Series C Shares, redeem or call for
redemption, purchase or otherwise pay off, retire or make any return of capital in respect of any shares of the Company ranking as to capital junior to the Series C Shares;

(c) redeem or call for redemption, purchase, or otherwise pay off or retire for value or make any return of capital in respect of less than all of the Series C Shares then outstanding; or

(d) except pursuant to any purchase obligation, sinking fund, retraction privilege or mandatory redemption provisions attaching thereto, redeem or call
for redemption, purchase or otherwise pay off, retire or make any return of capital in respect of any preferred shares, ranking as to the payment of dividends or return of capital on a parity with the Series C Shares;

unless, in each such case, all accrued and unpaid dividends up to and including the dividend payable for the last completed period for which dividends
were payable on the Series C Shares and on all other shares of the Company ranking prior to or on a parity with the Series C Shares with respect to the payment of dividends have been declared and paid or set apart for payment.

such date; provided that, if such rate does not appear on the Bloomberg Screen GCAN5YR Page on such date, the Government of Canada Yield will mean the average of the yields determined by two registered Canadian investment dealers selected by the
Company, as being the yield to maturity on such date (assuming semi-annual compounding) which a Canadian dollar denominated non-callable Government of Canada bond would carry if issued in Canadian dollars at 100% of its principal amount on such date

Initial Fixed Rate Period means the period commencing on the Closing Date
and ending on and including March 31, 2015.

Series E Shares registered in their name into Series F Shares on the basis of one Series F Share for each Series E Share. If a Series E Conversion Date would otherwise fall on a day that is not a business day, such Series E Conversion Date shall be
the immediately following business day. The conversion of Series E Shares may be effected upon notice given by the registered holders of the Series E Shares not earlier than the 30th day prior to, but not later than 5:00 p.m. (Toronto time) on the

notice in writing to the then registered holders of the Series E Shares of the Annual Fixed Dividend Rate for the next succeeding Subsequent Fixed Rate Period and the Floating Quarterly Dividend Rate (as defined below) applicable to the Series F
Shares for the next succeeding Quarterly Floating Rate Period.

If the Company gives notice to the registered holders of the Series E Shares
of the redemption on a Series E Conversion Date of all the Series E Shares, the Company will not be required to give notice as provided hereunder to the registered holders of the Series E Shares of an Annual Fixed Dividend Rate, a Floating Quarterly
Dividend Rate or of the conversion right of holders of Series E Shares and the right of any holder of Series E Shares to convert such Series E Shares will cease and terminate in that event.

Holders of Series E Shares will not be entitled to convert their shares into Series F Shares if the Company determines that there would remain outstanding on a Series E Conversion Date less than 1,000,000
Series F Shares, after having taken into account all Series E Shares tendered for conversion into Series F Shares and all Series F Shares tendered for conversion into Series E Shares. The Company will give notice in writing to all registered holders

having taken into account all Series E Shares tendered for conversion into Series F Shares and all Series F Shares tendered for conversion into Series E Shares, then, all, but not part, of the remaining outstanding Series E Shares will automatically

Series E Shares at least seven days prior to the Series E Conversion Date.

Upon exercise by a registered holder of its right to convert
Series E Shares into Series F Shares (and upon an automatic conversion), the Company reserves the right not to deliver Series F Shares to any person whose address is in, or whom the Company or its transfer agent has reason to believe is a resident
of, any jurisdiction outside Canada, to the extent that such issue would require the Company to take any action to comply with the securities or analogous laws of such jurisdiction.

Subject to applicable law and to the provisions described

return of capital in the event of the liquidation, dissolution or winding-up are not paid in full in respect of any series of the preferred shares, the preferred shares of all series will participate ratably in respect of such dividends in
accordance with the sums that would be payable on such shares if all such dividends were declared and paid in full, and in respect of such return of capital in accordance with the sums that would be payable on such return of capital if all sums so
payable were paid in full; provided, however, that if there are insufficient assets to satisfy in full all such claims, the claims of the holders of the preferred shares with respect to return of capital will be paid and satisfied first and any

unless, in each such case, all accrued and unpaid dividends up to and including the dividend payable for the last completed period for which dividends
were payable on the Series E Shares and on all other shares of the Company ranking prior to or on a parity with the Series E Shares with respect to the payment of dividends have been declared and paid or set apart for payment.

Creation or Issue of Additional Shares

Except in respect of the issuance of shares as a result of the conversion of the Series E Shares or other shares ranking prior to or on a parity with the Series E Shares in accordance with their terms or

Shares, create or issue any shares ranking prior to or on a parity with the Series E Shares with respect to repayment of capital or payment of dividends, provided that the Company may without such approval issue additional series of preferred shares

Voting Rights

The holders of the
Series G Shares will not (except as otherwise provided by law and except for meetings of the holders of Series G Shares as a series) be entitled to receive notice of, attend, or vote at, any meeting of shareholders of the Company unless and until
the Company shall have failed to pay eight quarterly dividends on the Series G Shares, whether or not consecutive and whether or not such dividends have been declared and whether or not there are any monies of the Company properly applicable to the
payment of dividends. In the event of such non-payment, and for only so long as any such dividends remain in arrears, the holders of the Series G Shares will be entitled to receive notice of and to attend each meeting of the Companys
shareholders at which directors are to be elected and to one vote for each Series G Share held. Upon payment of the entire amount of all Series G Share dividends in arrears, the voting rights of the holders of the Series G Shares shall forthwith
cease.

Tax Election

The terms of the Series G Shares will require the Company to elect, in the manner and within the time provided under Part VI.1 of the Income Tax Act
(Canada), to make the necessary election under Part VI.1 of the Tax Act so that corporate holders of Series G Shares will not be required to pay tax under Part IV.1 of the Tax Act on dividends received or deemed to be received on such shares.

Business Day

If any
action is required to be taken by the Company on a day that is not a business day, then such action will be taken on the next succeeding day that is a business day.

Description of the Series I Shares

The following is a summary of certain provisions attaching to the Series I Shares as a series.

Definition of Terms

The following definitions are relevant to the Series I Shares.

Annual Fixed Dividend Rate means, for any Subsequent Fixed Rate Period, the annual rate (expressed as a percentage
rate rounded down to the nearest one hundred-thousandth of one percent (with 0.000005% being rounded up)) equal to the sum of the Government of Canada Yield on the applicable Fixed Rate Calculation Date plus 2.85%.

Bloomberg Screen GCAN5YR Page means the display designated as page GCAN5YR<INDEX> on the Bloomberg Financial
L.P. service (or such other page as may replace the GCAN5YR page on that service) for purposes of displaying Government of Canada bond yields.

Fixed Rate Calculation Date means, for any Subsequent Fixed Rate Period, the 30th day prior to the first day of such Subsequent
Fixed Rate Period.

Government of Canada Yield on any date means the yield to maturity on such date (assuming
semi-annual compounding) of a Canadian dollar denominated non-callable Government of Canada bond with a term to maturity of five years as quoted as of 10:00 a.m. (Toronto time) on such date and which appears on the Bloomberg Screen GCAN5YR Page on
such date; provided that, if such rate does not appear on the Bloomberg Screen GCAN5YR Page on such date, the Government of Canada Yield will mean the average of the yields determined by two registered Canadian investment dealers selected by the
Company, as being the yield to maturity on such date (assuming semi-annual compounding) which a Canadian dollar denominated non-callable Government of Canada bond would carry if issued in Canadian dollars at 100% of its principal amount on such date
with a term to maturity of five years.

Initial Fixed Rate Period means the period commencing on the Closing Date
and ending on and including December 31, 2015.

Subsequent Fixed Rate Period means for the initial Subsequent
Fixed Rate Period, the period commencing on January 1, 2016 and ending on and including December 31, 2020 and for each succeeding Subsequent Fixed Rate Period, the period commencing on the day immediately following the end of the
immediately preceding Subsequent Fixed Rate Period and ending on and including December 31 in the fifth year thereafter.

Issue
Price

The Series I Shares will have an issue price of Cdn$25.00 per share.

Dividends

During the Initial Fixed Rate Period, the holders of the Series I Shares
will be entitled to receive fixed cumulative preferential cash dividends, as and when declared by the Board of Directors, payable quarterly on the last business day of March, June, September and December in each year during the Initial Fixed Rate
Period, at an annual rate equal to Cdn$1.25 per share. The initial dividend, if declared, will be payable December 31, 2010 and will be Cdn$0.29795 per share (less any tax required to be deducted and withheld by the Company), based on the
anticipated closing date of October 5, 2010.

During each Subsequent Fixed Rate Period, the holders of Series I Shares will be entitled
to receive fixed cumulative preferential cash dividends, as and when declared by the Board of Directors, payable quarterly on the last business day of March, June, September and December in each year during the Subsequent Fixed Rate Period, in an
annual amount per share determined by multiplying the Annual Fixed Dividend Rate applicable to such Subsequent Fixed Rate Period by Cdn$25.00 (less any tax required to be deducted and withheld by the Company).

The Annual Fixed Dividend Rate applicable to a Subsequent Fixed Rate Period will be determined by the Company on the Fixed Rate Calculation Date. Such
determination will, in the absence of manifest error, be final and binding upon the Company and upon all holders of Series I Shares. The Company will, on the Fixed Rate Calculation Date, give written notice of the Annual Fixed Dividend Rate for the
ensuing Subsequent Fixed Rate Period to the registered holders of the then outstanding Series I Shares.

The dividends on Series I Shares will
accrue on a daily basis. If, on any dividend payment date, the dividends accrued to such date are not paid in full on all of the Series I Shares then outstanding, such dividends, or the unpaid portion thereof, will be paid on a subsequent date or
dates determined by the Board of Directors on which the Company will have sufficient funds properly applicable to the payment of such dividends.



---

Redemption

The Series I Shares will not be redeemable by the Company prior to December 31, 2015. On December 31, 2015 and on December 31 every five years thereafter, and subject to certain other
restrictions set out in Restrictions on Dividends and Retirement and Issue of Shares below, the Company may, at its option, on at least 30 days and not more than 60 days prior written notice, redeem all or from time to time any part of
the outstanding Series I Shares by payment in cash of a per share sum equal to Cdn$25.00, in each case plus an amount equal to the sum of (i) all unpaid dividends (whether or not declared) in respect of completed quarters preceding up to but
excluding the date fixed for redemption; and (ii) an amount equal to the cash dividend in respect of the quarter in which the redemption occurs pro rated to such date (less any tax required to be deducted and withheld by the Company).

If less than all of the outstanding Series I Shares are to be redeemed, the shares to be redeemed shall be selected on a pro rata basis
disregarding fractions or, if such shares are at such time listed on an exchange, with the consent of such exchange, in such manner as the Board of Directors in its sole discretion may, by resolution, determine.

The Series I Shares do not have a fixed maturity date and are not redeemable at the option of the holders of Series I Shares. See Risk
Factors.

Conversion of Series I Shares into Series J Shares

Holders of Series I Shares will have the right, at their option, on December 31, 2015 and on December 31 every five years thereafter (each, a Series I Conversion Date), to
convert, subject to applicable law and the restrictions on conversion described below and the payment or delivery to the Company of evidence of payment of the tax (if any) payable, all or any of their Series I Shares registered in their name into
Series J Shares on the basis of one Series J Share for each Series I Share. If a Series I Conversion Date would otherwise fall on a day that is not a business day, such Series I Conversion Date shall be the immediately following business day. The
conversion of Series I Shares may be effected upon notice given by the registered holders of the Series I Shares not earlier than the 30th day prior to, but not later than 5:00 p.m. (Toronto time) on the 15th day preceding, a Series I Conversion
Date. Once received by the Company, an election notice is irrevocable.

The Company will, at least 30 days and not more than 60 days prior to
the applicable Series I Conversion Date, give notice in writing to the then registered holders of Series I Shares of the above-mentioned conversion right. On the 30th day prior to each Series I Conversion Date, the Company will give notice in
writing to the then registered holders of the Series I Shares of the Annual Fixed Dividend Rate for the next succeeding Subsequent Fixed Rate Period and the Floating Quarterly Dividend Rate (as defined below) applicable to the Series J Shares for
the next succeeding Quarterly Floating Rate Period.

If the Company gives notice to the registered holders of the Series I Shares of the
redemption on a Series I Conversion Date of all the Series I Shares, the Company will not be required to give notice as provided hereunder to the registered holders of the Series I Shares of an Annual Fixed Dividend Rate, a Floating Quarterly
Dividend Rate or of the conversion right of holders of Series I Shares and the right of any holder of Series I Shares to convert such Series I Shares will cease and terminate in that event.

Holders of Series I Shares will not be entitled to convert their shares into Series J Shares if the Company determines that there would remain outstanding on a Series I Conversion Date less than 1,000,000
Series J Shares, after having taken into account all Series I Shares tendered for conversion into Series J Shares and all Series J Shares tendered for conversion into Series I Shares. The Company will give notice in writing to all registered holders
of Series I Shares of their inability to convert their Series I Shares at least seven days prior to the applicable Series I Conversion Date. Furthermore, if the Company determines that there would remain outstanding on a Series I Conversion Date
less than 1,000,000 Series I Shares, after having taken into account all Series I Shares tendered for conversion into Series J Shares and all Series J Shares tendered for conversion into Series I Shares, then, all, but not part, of the remaining
outstanding Series I Shares will automatically be converted into Series J Shares on the basis of one Series J Share for each Series I Share, on the applicable Series I Conversion Date and the Company will give notice in writing to this effect to the
then registered holders of such remaining Series I Shares at least seven days prior to the Series I Conversion Date.

Upon exercise by a
registered holder of its right to convert Series I Shares into Series J Shares (and upon an automatic conversion), the Company reserves the right not to deliver Series J Shares to any person whose address is in, or whom the Company or its transfer
agent has reason to believe is a resident of, any jurisdiction outside Canada, to the extent that such issue would require the Company to take any action to comply with the securities or analogous laws of such jurisdiction.

Purchase for Cancellation

Subject to applicable law and to the provisions described under Restrictions on Dividends and Retirement and Issue of Shares below, the
Company may at any time purchase for cancellation the whole or any part of the Series I Shares at the lowest price or prices at which, in the opinion of the Board of Directors, such shares are obtainable.

Rights on Liquidation

In the event of the liquidation, dissolution or winding-up of the Company or any other distribution of assets of the Company among its shareholders for the purpose of winding-up its affairs, the holders
of the Series I Shares will be entitled to receive Cdn$25.00 per share, together with all accrued and unpaid dividends (whether or not declared) up to but excluding the date of payment or distribution (less any tax required to be deducted or
withheld by the Company), before any amount is paid or any assets of the Company are distributed to the holders of the Companys multiple voting shares, subordinate voting shares and any other shares ranking junior as to capital to the Series I
Shares. Upon payment of such amounts, the holders of the Series I Shares will not be entitled to share in any further distribution of the assets of the Company.

Priority

The Series I Shares shall rank on a parity with the preferred shares of
every other series with respect to dividends and distribution of assets in the event of the liquidation, dissolution or winding-up, and will be entitled to a preference over the Companys subordinate voting shares and multiple voting shares and
over any other shares ranking junior to the preferred shares with respect to priority in payment of dividends and in the distribution of assets in the event of the Companys liquidation, dissolution or winding-up, whether voluntary or
involuntary, or any other distribution of the Companys assets among shareholders for the purpose of winding-up its affairs. If any cumulative dividends, whether or not declared, or declared non-cumulative dividends or amounts payable on a
return of capital in the event of the liquidation, dissolution or winding-up are not paid in full in respect of any series of the preferred shares, the preferred shares of all series will participate ratably in respect of such dividends in
accordance with the sums that would be payable on such shares if all such dividends were declared and paid in full, and in respect of such return of capital in accordance with the sums that would be payable on such return of capital if all sums so
payable were paid in full; provided, however, that if there are insufficient assets to satisfy in full all such claims, the claims of the holders of the preferred shares with respect to return of capital will be paid and satisfied first and any
assets remaining thereafter will be applied towards the payment and satisfaction of claims in respect of dividends.

Restrictions on
Dividends and Retirement and Issue of Shares

So long as any of the Series I Shares are outstanding, the Company will not, without the
approval of the holders of the Series I Shares:

(a) declare, pay or set apart for payment any dividends (other than stock dividends payable in
shares of the Company ranking as to capital and dividends junior to the Series I Shares) on shares of the Company ranking as to dividends junior to the Series I Shares;

(b) except out of the net cash proceeds of a substantially concurrent issue of shares of the Company ranking as to return of capital and dividends junior to the Series I Shares, redeem or call for
redemption, purchase or otherwise pay off, retire or make any return of capital in respect of any shares of the Company ranking as to capital junior to the Series I Shares;

(c) redeem or call for redemption, purchase, or otherwise pay off or retire for value or make any return of capital in respect of less than all of the Series I Shares then outstanding; or

(d) except pursuant to any purchase obligation, sinking fund, retraction privilege or mandatory redemption provisions attaching thereto, redeem or call
for redemption, purchase or otherwise pay off, retire or make any return of capital in respect of any preferred shares, ranking as to the payment of dividends or return of capital on a parity with the Series I Shares;

unless, in each such case, all accrued and unpaid dividends up to and including the dividend payable for the last completed period for which dividends
were payable on the Series I Shares and on all other shares of the Company ranking prior to or on a parity with the Series I Shares with respect to the payment of dividends have been declared and paid or set apart for payment.

Creation or Issue of Additional Shares

Except in respect of the issuance of shares as a result of the conversion of the Series I Shares or other shares ranking prior to or on a parity with the Series I Shares in accordance with their terms or
the issuance of Series I Shares as a result of the conversion of the Series J Shares in accordance with their terms, so long as any Series I Shares are outstanding, the Company will not, without the prior approval of the holders of the Series I
Shares, create or issue any shares ranking prior to or on a parity with the Series I Shares with respect to repayment of capital or payment of dividends, provided that the Company may without such approval issue additional series of preferred shares
ranking on a parity with the Series I Shares if all dividends (whether or not declared) then payable on the Series I Shares shall have been paid or set apart for payment.

Shareholder Approvals

In addition to any other approvals required by law, the approval of all amendments to the rights, privileges, restrictions and
conditions attaching to the Series I Shares as a series and any other approval to be given by the holders of the Series I Shares may be given by a written resolution signed by all the holders of the Series I Shares or by a resolution carried by an
affirmative vote of at least 66 2/3% of the votes
cast at a meeting at which the holders of a majority of the outstanding Series I Shares are present or represented by proxy or, if no quorum is present at such meeting, at an adjourned meeting at which the holders of Series I Shares then present
would form the necessary quorum. At any meeting of holders of Series I Shares as a series, each such holder shall be entitled to one vote in respect of each Series I Share held.

Voting Rights

The holders of the Series I Shares will not (except as otherwise
provided by law and except for meetings of the holders of Series I Shares as a series) be entitled to receive notice of, attend, or vote at, any meeting of shareholders of the Company unless and until the Company shall have failed to pay eight
quarterly dividends on the Series I Shares, whether or not consecutive and whether or not such dividends have been declared and whether or not there are any monies of the Company properly applicable to the payment of dividends. In the event of such
non-payment, and for only so long as any such dividends remain in arrears, the holders of the Series I Shares will be entitled to receive notice of and to attend each meeting of the Companys shareholders at which directors are to be elected
and to one vote for each Series I Share held. Upon payment of the entire amount of all Series I Share dividends in arrears, the voting rights of the holders of the Series I Shares shall forthwith cease.

Tax Election

The terms of the
Series I Shares will require the Company to elect, in the manner and within the time provided under Part VI.1 of the Tax Act, to make the necessary election under Part VI.1 of the Tax Act so that corporate holders of Series I Shares will not be
required to pay tax under Part IV.1 of the Tax Act on dividends received or deemed to be received on such shares.

Business Day

If any action is required to be taken by the Company on a day that is not a business day, then such action will be taken on the next
succeeding day that is a business day.
