Section 4.

Dividends.

(a) Quarterly
Dividends.

(i) Holders shall be entitled to receive, if, as and when declared by the Board of Directors or any duly
authorized committee thereof, out of assets legally available for the payment of dividends under Bermuda law, cumulative cash dividends on the Original Liquidation Preference at a rate per annumequal to 6%, payable quarterly in arrears (the
Quarterly Dividends) on each February 15, May 15, August 15 and November 15, commencing on August 15, 2008; provided, however, if any such day is not a Business Day, then payment of
any Quarterly Dividend otherwise payable on that date will be made on the next succeeding day that is a Business Day, unless that day falls in the next calendar year, in which case payment of such Quarterly Dividend will occur on the immediately
preceding Business Day (each such day on which Quarterly Dividends are payable, after giving effect to this proviso if applicable, a Quarterly Dividend Payment Date). The period from and including the date of issuance of the
Convertible Preference Shares (the Issue Date) or any Quarterly Dividend Payment Date to, but excluding, the next Quarterly Dividend Payment Date is a Quarterly Dividend Period. (It is understood that the number
of days on which Quarterly Dividends may accrue in any Quarterly Dividend Period may increase or decrease pursuant to the proviso in the second preceding sentence, but no interest or other payment shall be due in respect of any payment date deferral
pursuant to such proviso.) The Quarterly Dividends shall begin to accumulate on the Issue Date and shall be deemed to accumulate from day to day whether or not earned or declared until paid. The record date for payment of Quarterly Dividends on the
Convertible Preference Shares will be the first day of the calendar month during which the Quarterly Dividend Payment Date falls or such other record date,



-8-



---

if any, as may be fixed by the Board of Directors or any duly authorized committee thereof that is not more than 30 nor less than 10 days prior to such
Quarterly Dividend Payment Date (a Quarterly Dividend Record Date). Any such day that is a Quarterly Dividend Record Date will be a Quarterly Dividend Record Date whether or not such day is a Business Day. The amount of Quarterly
Dividends payable will be computed on the basis of a 360-day year of twelve 30-day months.

(ii) Quarterly Dividends, may,
at the option of the Company, be paid in cash or by issuing fully paid and nonassessable Common Shares or by a combination thereof. If the Company elects to pay Quarterly Dividends in Common Shares, the number of Common Shares to be paid in respect
of such Quarterly Dividends will be calculated by dividing the amount of such payment by 95% of the Current Market Price as of the date such payment is made.

(b) Participating Dividends. Holders shall be entitled to participate in any dividends paid on outstanding Common Shares in an amount equal, for each Convertible Preference Share, to the amount of such
dividends as would be paid on the largest number of Common Shares into which such Convertible Preference Share could be converted on the date of payment of such dividends on the outstanding Common Shares, assuming such converted Common Shares were
outstanding on the applicable record date for such dividend (Participating Dividends). Each Participating Dividend will be paid on the day that the corresponding dividend on the outstanding Common Shares is paid. However, no
dividend or other distribution on outstanding Common Shares shall give rise to a Participating Dividend if it consists solely of Junior Shares (where the powers, preferences and rights of the dividend shares are substantially the same as those of
the shares on which the dividend is being paid) and gives rise to an adjustment of the Conversion Rate pursuant to Section 10. The record date for payment of the Participating Dividends on the Convertible Preference Shares will be the record
date for the payment of the corresponding dividend on the outstanding Common Shares as fixed by the Board of Directors or any duly authorized committee thereof. The Company has no obligation whatsoever to declare or pay any dividends on outstanding
Common Shares with respect to any or all periods, and no obligation to pay Participating Dividends except to the extent, if any, that it has declared and paid dividends on outstanding Common Shares as provided above.

(c) Cumulative Dividends. Quarterly Dividends on the Convertible Preference Shares shall be cumulative, and from and after any Quarterly Dividend
Payment Date on which any dividend or any payment upon redemption or conversion that has accumulated or been deemed to have accumulated through such date has not been paid in full (the Arrearage), additional dividends shall
accumulate in respect of the Arrearage at the rate per annum of 6%. Such additional dividends in respect of any Arrearage shall be deemed to accumulate quarterly on each Quarterly Dividend Payment Date whether or not earned or declared until the
Arrearage is paid, shall be calculated as of such Quarterly Dividend Payment Date and shall constitute additional Arrearage from and after such Quarterly Dividend Payment Date to the extent not paid on such Quarterly Dividend Payment Date.
References in any Article herein to dividends that have accumulated or that have been deemed to have accumulated with respect to the Convertible Preference Shares shall include the amount, if any, of any Arrearage together with any
dividends accumulated or deemed to have accumulated on such Arrearage pursuant to the immediately preceding two sentences.



-9-



---

(d) Priority of Dividends. So long as any Convertible Preference Shares remain issued and
outstanding, the Company will not, and will cause its Subsidiaries not to, declare, pay or set apart funds for any dividends or other distributions with respect to any Junior Shares or redeem, repurchase or otherwise acquire, or make a liquidation
payment relating to, any Junior Shares, or make any guarantee payment with respect thereto, in any case during or in respect of any Quarterly Dividend Period, unless full dividends (including any Arrearage and dividends accumulated in respect
thereof) have been or contemporaneously are declared and paid (or declared and a sum sufficient for the payment of those dividends has been set apart for such payment) on the Convertible Preference Shares for all Quarterly Dividend Periods
terminating on or prior to the date of such declaration, payment, repurchase, redemption or acquisition; provided, however, that the foregoing restriction will not apply to:

(i) purchases, redemptions or other acquisitions of Junior Shares (and the payment of cash in lieu of fractional shares in connection
therewith) in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors or consultants of the Company or any Subsidiary;

(ii) purchases of Common Shares pursuant to a contractually binding requirement (which the Company is not entitled to lawfully terminate)
to buy shares existing prior to the commencement of the then-current Quarterly Dividend Period, including under a contractually binding share repurchase plan;

(iii) as a result of an exchange or conversion of any class or series of Junior Shares for any other class or series of Junior Shares;

(iv) the purchase of fractional interests in Junior Shares pursuant to the conversion or exchange provisions of such Junior
Shares or the security being converted or exchanged; or

(v) the purchase of Junior Shares by a broker or dealer subsidiary
of the Company in connection with market-making or other secondary market activities in the ordinary course of the business of such subsidiary.

The
foregoing restriction, however, will not apply to any dividends paid in the form of Junior Shares where the powers, preferences and rights of the dividend shares are substantially the same as those of the shares on which the dividend is being paid.

For so long as any Convertible Preference Shares remain issued and outstanding, if full dividends (including any Arrearage and dividends
accumulated in respect thereof) are not paid in full (or declared and a sum sufficient for such full payment is not so set apart) for any Quarterly Dividend Period on the Convertible Preference Shares and any Parity Dividend Shares, dividends
declared on the Convertible Preference Shares and such Parity Dividend Shares shall



-10-



---

only be declared pro rata based upon the respective amounts that would have been paid on the Convertible Preference Shares and such Parity Dividend
Shares had dividends (including any Arrearage and dividends accumulated in respect thereof) been declared and paid in full.

Subject to the
foregoing, such dividends payable in cash, shares or otherwise as may be determined by the Board of Directors, or any duly authorized committee thereof, may be declared and paid on any Junior Shares and Parity Shares from time to time out of any
assets legally available for such payment, and (except for Participating Dividends as provided in Section 4(b)) Holders will not be entitled to participate in those dividends.

Section 5.

Liquidation Rights.

(a) Liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, Holders shall
be entitled, out of assets legally available therefor, before any distribution or payment out of the assets of the Company may be made to or set aside for the holders of any Junior Liquidation Shares and subject to the rights of the holders of any
class or series of securities ranking senior to or on parity with Convertible Preference Shares upon liquidation and the rights of the Companys creditors, to receive in full in respect of each Convertible Preference Share a liquidating
distribution in the amount of the greater of (x) the Original Liquidation Preference plus all accumulated and unpaid dividends in respect of such share, whether or not declared (including Arrearage and dividends accumulated in respect thereof)
to, but excluding, the date fixed for liquidation, dissolution or winding up (the Liquidation Preference) and (y) the amount the Holders would have received if such Holders converted all of their Convertible Preference Shares
pursuant to Section 7 hereof on the date fixed for liquidation, dissolution or winding up. Holders shall not be entitled to any further payments in the event of any such voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Company other than what is expressly provided for in this Section 5. For the avoidance of doubt, the Liquidation Preference does not include any Participating Dividends.

(b) Partial Payment. If, upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, the assets of the
Company are not sufficient to pay the liquidating distributions payable with respect to the Convertible Preference Shares and the Parity Liquidation Shares, the amounts paid to the Holders and to the holders of all Parity Liquidation Shares shall be
paid pro ratain accordance with the respective aggregate liquidating distributions to which they would otherwise be entitled.

(c)
Residual Distributions. If the respective aggregate liquidating distributions to which all Holders and all holders of any Parity Liquidation Shares are entitled have been paid, the holders of Junior Liquidation Shares shall be entitled to
receive all remaining assets of the Company according to their respective rights and preferences.

(d) Consolidation, Merger,
Amalgamation, Scheme of Arrangement and Sale of Assets Not Liquidation. For purposes of this Section 5, the sale, lease or other disposition (for cash, shares, securities or other consideration) of all or substantially all of the assets of
the



-11-



---

Company shall not be deemed a voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, nor shall the consolidation,
merger, amalgamation, scheme of arrangement, other binding share exchange or reclassification or any similar transaction involving the Company (whether or not the Company is the surviving or resulting entity) be deemed to be a voluntary or
involuntary dissolution, liquidation or winding up of the affairs of the Company.

Section 6.

Redemption.

(a) Optional
Redemption. The Company, at the option of its Board of Directors or any duly authorized committee thereof, may redeem out of funds legally available therefor, in whole or in part, the Convertible Preference Shares at the time issued and
outstanding, on any one or more Quarterly Dividend Payment Dates on or after May 15, 2013, upon notice given as provided in Section 6(b) below, and at a redemption price equal to the Liquidation Preference (calculated as if the date of
redemption was the date fixed for liquidation, dissolution or winding up); providedthat the Company shall only be entitled to redeem the Convertible Preference Shares of any Holder if such redemption is treated (in the Companys
reasonable determination after due inquiry) with respect to such Holder as a distribution in exchange for such Holders Convertible Preference Share within the meaning of Section 302(a) of the Internal Revenue Code of 1986, as amended.

Notwithstanding the foregoing, the Company, at the option of its Board of Directors or any duly authorized committee thereof, may redeem
out of funds legally available therefor, at any time, in whole but not in part, the Convertible Preference Shares at the time issued and outstanding if the aggregate Liquidation Preference of such shares is equal to 10% or less of the aggregate
Liquidation Preference of all Convertible Preference Shares originally issued by the Company, upon notice as provided in Section 6(b) below, and at a redemption price equal to the Liquidation Preference (calculated as if the date of redemption
was the date fixed for liquidation, dissolution or winding up).

(b) Notice of Redemption. Notice of every redemption of the
Convertible Preference Shares shall be mailed by first class mail, postage prepaid, addressed to the Holders of such shares to be redeemed at their respective last addresses appearing on the register of Members of the Company. Such mailing shall be
at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this Section 6(b) shall be conclusively presumed to have been duly given, whether or not any Holder receives such
notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any Holder of the Convertible Preference Shares designated for redemption shall not affect the validity of the proceedings for the
redemption of any other Convertible Preference Shares. Each notice shall state:

(i) the redemption date;



-12-



---

(ii) the number of Convertible Preference Shares to be redeemed and, if fewer than all
the shares of a Holder are to be redeemed, the number of such shares to be redeemed;

(iii) the redemption price;

(iv) the place or places where the certificates for such shares are to be surrendered for payment of the redemption price;
and

(v) that dividends on the shares to be redeemed will cease to accumulate on the redemption date.

Notwithstanding the foregoing, if the Convertible Preference Shares are held in book-entry form through a Depositary, the Company may give such notice in
any manner permitted by the Depositary.

(c) Partial Redemption. In case of any redemption of only part of the Convertible
Preference Shares at the time issued and outstanding, the Convertible Preference Shares to be redeemed shall be selected pro ratafrom the Holders in proportion to the number of Convertible Preference Shares held by such Holders, by lot or in
such other manner as the Board of Directors or any duly authorized committee thereof may determine to be fair and equitable. Subject to the provisions of this Section 6, the Board of Directors or any duly authorized committee thereof shall have
full power and authority to prescribe the terms and conditions upon which the Convertible Preference Shares shall be redeemed from time to time.

(d) Effectiveness of Redemption. If notice of redemption has been duly given and if on or before the redemption date specified in the notice all funds necessary for the redemption have been set aside by the Company, separate and
apart from its other assets, in trust for the pro ratabenefit of the Holders of the shares called for redemption, so as to be and continue to be available therefor, or deposited by the Company with a bank or trust company selected by the
Board of Directors or any duly authorized committee thereof in trust for the pro rata benefit of the Holders of the shares called for redemption (the Trust), then, notwithstanding that any certificate for any share so
called for redemption has not been surrendered for cancellation, on and after the redemption date all shares so called for redemption shall cease to be issued and outstanding, all dividends with respect to such shares shall cease to accumulate on
such redemption date and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the Holders thereof to receive the amount payable on such redemption from the Trust at any time
after the redemption date from the funds so deposited, without interest. The Company shall be entitled to receive, from time to time, from the Trust any interest accrued on such funds, and the Holders of any shares called for redemption shall have
no claim to any such interest. Any funds so deposited and unclaimed at the end of three years from the redemption date shall, to the extent permitted by law, be released or repaid to the Company, and in the event of such repayment to the Company,
the Holders of the shares so called for redemption shall be deemed to be unsecured creditors of the Company for an amount equivalent to the amount deposited as stated above for the redemption of such shares and so repaid to the Company, but shall in
no event be entitled to any interest.



-13-



---

(e) Conversion Prior to Redemption. If the Convertible Preference Shares have been called for
redemption, a Holder will be entitled to convert the Convertible Preference Shares from the date of notice of the redemption until the close of business on the second Business Day immediately preceding the date of redemption.

(f) Reduction of Share Capital. Any redemption of Convertible Preference Shares under this Section 6 shall not be taken as reducing the
amount of the Companys authorized share capital.

Section 7.

Right of the Holders to Convert.

Each Holder shall have the right, at such
Holders option (including after a notice of redemption has been given but prior to the date of actual redemption), to convert all or any portion of such Holders Convertible Preference Shares at any time into (a) Common Shares at the
then-applicable Conversion Rate per share of Convertible Preference Shares (subject to the conversion procedures of Section 8), plus cash in lieu of fractional shares plus (b) cash, fully paid and nonassessable Common Shares or a
combination thereof (which determination shall be made at the option of the Company) in respect of any and all accumulated and unpaid dividends on the Convertible Preference Shares so converted, whether or not declared (including Arrearage and
dividends accumulated in respect thereof) to, but excluding, the applicable Conversion Date, provided that if the Company elects to pay any or all such dividends in Common Shares the number of Common Shares to be distributed in respect thereof will
be calculated by dividing the amount of such dividend payment by 95% of the Current Market Price as of the Conversion Date.

Section 8.

Conversion Procedures.

(a) Conversion Date.Effective immediately prior to the close of business on any applicable Conversion Date, dividends shall no longer be declared on any such converted Convertible Preference Shares and such
Convertible Preference Shares shall cease to be issued and outstanding, in each case, subject to the right of Holders to receive any payments to which they are entitled pursuant to the terms hereof.

(b) Rights Prior to Conversion. No allowance or adjustment, except pursuant to Section 10, shall be made in respect of dividends payable to
holders of the Common Shares of record as of any date prior to the close of business on any applicable Conversion Date. Prior to the close of business on any applicable Conversion Date, Common Shares issuable upon conversion of, or other securities
issuable upon conversion of, any Convertible Preference Shares shall not be deemed issued and outstanding for any purpose, and Holders shall have no rights

---

with respect to the Common Shares or other securities issuable upon conversion (including voting rights, rights to respond to tender offers for the Common
Shares or other securities issuable upon conversion and rights to receive any dividends or other distributions on the Common Shares or other securities issuable upon conversion) by virtue of holding Convertible Preference Shares; providedthat nothing in this Section 8(b) shall be deemed to restrict or limit the rights of Holders under the terms of the Convertible Preference Shares themselves, including the voting rights set forth in Section 12 and the rights to
dividends and liquidating distributions set forth in Section 4 and Section 5, respectively.

(c) Reacquired Shares.Convertible Preference Shares duly converted in accordance with this Certificate of Designations, or otherwise reacquired by the Company, will resume the status of authorized and unissued preference shares without designation as to series, until
such shares are once more designated as part of a particular series by the Board of Directors.

(d) Record Holder as of Conversion Date.The Person or Persons entitled to receive the Common Shares and/or cash, securities or other property issuable upon conversion of the Convertible Preference Shares shall be treated for all purposes as the record holder(s) of such Common Shares
and/or securities as of the close of business on any applicable Conversion Date. In the event that a Holder shall not by written notice designate the name in which Common Shares and/or cash, securities or other property (including payments of cash
in lieu of fractional shares) to be issued or paid upon conversion of Convertible Preference Shares should be registered or paid or the manner in which such shares should be delivered, the Company shall be entitled to register and deliver such
shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Company or, in the case of global certificates, through book-entry transfer through the Depositary.

(e) Conversion Procedure. On the date of any conversion, if a Holders interest is in certificated form, a Holder must do each of the
following in order to convert:

(i) complete and manually sign the conversion notice provided by the Conversion Agent, or a
facsimile of the conversion notice, and deliver this notice to the Conversion Agent, provided that such notice may, pursuant to a written notice thereunder be made contingent upon (but only upon) the successful completion of any registered public
offering of the Common Shares to be issued on such conversion that is being conducted pursuant to the Registration Agreement at such time and such notice shall in all other respects be irrevocable;

(ii) surrender the Convertible Preference Shares to the Conversion Agent;

(iii) if required, furnish appropriate endorsements and transfer documents; and

(iv) if required, pay any share transfer, documentary, stamp or similar taxes not payable by the Company pursuant to Section 23.

If a Holders interest is a beneficial interest in a global certificate representing Convertible Preference Shares, in order to
convert a Holder must comply with clauses (iii) and



-15-



---

(iv) listed above and comply with the Depositarys procedures for converting a beneficial interest in a global security. The date on which a Holder
complies with the applicable procedures in this Section 8(e) is the Conversion Date; provided that, if such date is not a Business Day or such compliance does not occur prior to the close of business on such date, the
Conversion Date shall be the next Business Day. The Conversion Agent shall, on a Holders behalf, convert the Convertible Preference Shares into Common Shares, in accordance with the terms of the notice delivered by such Holder described in
clause (i) above (or otherwise pursuant to any applicable Depositary procedures).

Section 9.

Conversion at the Option of the Company.

(a) Company Conversion Right.At any time or from time to time on or after May 15, 2013 if, for any 20 Trading Days (whether or not consecutive) within a period of thirty (30) consecutive Trading Days ending on the
Trading Day preceding the date the Company delivers a Notice of Conversion at the Option of the Company, the Closing Price of the Common Shares exceeds 125% of the then-applicable Conversion Price of the Convertible Preference Shares, the Company
shall have the right, at its option, to cause some or all of the Convertible Preference Shares to be converted into (a) Common Shares at the then-applicable Conversion Rate, plus cash in lieu of fractional shares, plus (b) cash, fully paid
and nonassessable Common Shares or a combination thereof (which determination shall be made at the option of the Company) in respect of any and all accumulated and unpaid dividends on the Convertible Preference Shares so converted, whether or not
declared (including Arrearage and dividends accumulated in respect thereof) to, but excluding, the Conversion at the Option of the Company Date; provided that if the Company elects to pay any or all such dividends in Common Shares the number
of Common Shares to be distributed in respect thereof will be calculated by dividing the amount of such dividend payment by 95% of the Current Market Price as of the Conversion at the Option of the Company Date. On the date the Company delivers a
Notice of Conversion at the Option of the Company all Common Shares issued upon such conversion are Freely Tradeable and may be immediately resold by the Holder at such time and for a period of no less than 30 days thereafter without restriction
under any trading policies that might otherwise be applicable to such Holder by virtue of its having designees on the Board of Directors or otherwise.

(b) Partial Conversion.If the Company elects to cause less than all the Convertible Preference Shares to be converted under Section 9(a), the Conversion Agent shall select the Convertible Preference
Shares to be converted on a pro rata basis. If the Conversion Agent selects a portion of a Holders Convertible Preference Shares for partial conversion at the option of the Company and such Holder converts a portion of its Convertible
Preference Shares, the converted portion will be deemed to be the portion selected for conversion at the option of the Company under this Section 9.

(c) Conversion Procedure.In order to exercise the conversion right described in this Section 9, the Company shall provide notice of such conversion to each Holder (such notice,



-16-



---

a Notice of Conversion at the Option of the Company). The Conversion Date shall be a date selected by the Company (the Conversion
at the Option of the Company Date) and shall be no more than 20 days after the date on which the Company provides such Notice of Conversion at the Option of the Company. In addition to any information required by applicable law or
regulation, the Notice of Conversion at the Option of the Company shall state, as appropriate:

(i) the Conversion at the
Option of the Company Date;

(ii) the number of Common Shares to be issued upon conversion of each of the Convertible
Preference Shares and, if fewer than all the shares of a Holder are to be converted, the number of the Holders shares to be converted;

(iii) in reasonable detail, the calculations and supporting data used by the Company in its determination that it had the right to effect such conversion; and

(iv) the total number of Convertible Preference Shares to be converted.

Notwithstanding the foregoing, (x) if the Convertible Preference Shares are held in book-entry form through a Depositary, the Company may give such notice in any manner permitted by the Depositary and
(y) the Holder shall have the right to exercise its right to convert pursuant to Section 7 hereof at any time prior to the Conversion at the Option of the Company Date, and the exercise by the Holder of such right shall supersede and
prevail over the exercise by the Company of its rights under this Section 9.

Section 10.

(a)
Adjustments.The Conversion Rate will be subject to adjustment, without duplication, under the following circumstances:

(i) the issuance of Common Shares as a dividend, bonus shares or distribution to all holders of Common Shares, or a subdivision or combination of Common Shares, in which event the Conversion Rate will be adjusted based on the following

(b) Calculation of Adjustments. Each adjustment to the Conversion Rate shall be calculated
by the Company as soon as reasonably practicable after the event requiring such adjustment has been consummated (and all factors necessary to calculate such adjustment are

known), in each case to the nearest 1/10,000thof one
Common Share (or if there is not a nearest 1/10,000thof a share, to the next lower 1/10,000thof a share). Notwithstanding anything herein to the contrary, except in the case of a combination or reverse stock split of Common Shares pursuant to Section 10(a)(i), in no
case will any adjustment be made if it would result in a decrease to the then effective Conversion Rate. No adjustment to the Conversion Rate will be required unless such adjustment would require an increase or decrease of at least one percent;
provided, however, that any such minor adjustments that are not required to be made, and are not made, will be carried forward and taken into account in any subsequent adjustment; and provided further that any such adjustment of
less than one percent that has not been made will be made upon (x) the date of any notice of redemption of the Convertible Preference Shares in accordance with the provisions hereof and (y) any Conversion Date.

(c) When No Adjustment Required.

(i) Except as otherwise provided in this Section 10, the Conversion Rate will not be adjusted for the issuance of Common Shares or any securities convertible into or exchangeable for Common Shares or carrying the
right to purchase any of the foregoing or for the repurchase of Common Shares.

(ii) No adjustment of the Conversion Rate
need be made as a result of: (A) the issuance of the rights; (B) the distribution of separate certificates representing the rights; (C) the exercise or redemption of the rights in accordance with any rights agreement; or (D) the
termination or invalidation of the rights, in each case, pursuant to the Companys shareholder rights plan existing on the date of hereof, as amended, modified or supplemented from time to time, or any newly adopted shareholder rights plans;
provided, however, that to the extent that the Company has a shareholder rights plan in effect on a Conversion Date (including the Companys rights plan existing on the date hereof), the Holder shall receive, in addition to the
Common Shares, the rights under such rights plan, unless (for the existing plan or a future plan with substantially similar provisions), prior to any such Conversion Date, the rights have separated from the Common Shares, in which case the
Conversion Rate will be adjusted at the time of separation as if the Company made a distribution to all holders of Common Shares or evidences of its indebtedness or its assets as described in Section 10(a)(iii), subject to readjustment in the
event of the expiration, termination or redemption of the rights.

(iii) No adjustment to the Conversion Rate need be made:

(A) upon the issuance of any Common Shares pursuant to any present or future customary plan providing for the reinvestment
of dividends or interest payable on securities of the Company and the investment, at market prices, of additional optional amounts in Common Shares; or

(B) upon the issuance of any Common Shares or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any
of its Subsidiaries or other Affiliates.



-21-



---

(iv) No adjustment to the Conversion Rate will be made to the extent that such adjustment
would result in the Conversion Price being less than the par value of the Common Shares.

(v) Notwithstanding any other
provision herein to the contrary, no adjustment shall be made in respect of an event otherwise requiring an adjustment under this Section 10 except to the extent such event is actually consummated.

(vi) No adjustment shall be made in respect of any dividend or other distribution giving rise to a Participating Dividend.

(d) Record Date.For purposes of this Section 10, Record Date means, with respect to any dividend, distribution or other
transaction or event in which the holders of the Common Shares have the right to receive any cash, securities or other property or in which the Common Shares (or other applicable security) are exchanged for or converted into any combination of cash,
securities or other property, the date fixed for determination of holders of the Common Shares entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(e) Successive Adjustments.After an adjustment to the Conversion Rate under this Section 10, any subsequent event requiring
an adjustment under this Section 10 shall cause an adjustment to such Conversion Rate as so adjusted.

(f) Multiple Adjustments.For the avoidance of doubt, if an event occurs that would trigger an adjustment to the Conversion Rate pursuant to this Section 10 under more than one subsection hereof, such event, to the extent taken into account in any adjustment, shall
not result in any other adjustment hereunder.

(g) Other Adjustments.The Company may, but shall not be required to, make such
increases in the Conversion Rate, in addition to those required by this Section 10, as the Board of Directors considers to be advisable in order to avoid or diminish any income tax to any holders of Common Shares resulting from any dividend or
distribution of shares or issuance of rights or warrants to purchase or subscribe for shares or from any event treated as such for income tax purposes or for any other reason.

(h) Notice of Adjustments.Whenever a Conversion Rate is adjusted as provided under this Section 10, the Company shall within
10 Business Days following the occurrence of an event that requires such adjustment (or if the Company is not aware of such occurrence, within 10 Business Days after becoming so aware) or, if the Company makes an adjustment pursuant to
Section 10(g), within 10 Business Days after such adjustment:

(i) compute the adjusted applicable Conversion Rate in
accordance with this Section 10 and prepare and transmit to the Conversion Agent an Officers Certificate



-22-



---

setting forth such adjusted applicable Conversion Rate, the method of calculation thereof in reasonable detail and the facts requiring such adjustment and
upon which such adjustment is based; and

(ii) provide a written notice to the Holders of the occurrence of such event and a
statement in reasonable detail setting forth the method by which the adjustment to the applicable Conversion Rate was determined and setting forth the adjusted applicable Conversion Rate.

(i) Conversion Agent.The Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine whether any facts
exist that may require any adjustment of the applicable Conversion Rate or with respect to the nature, extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. The Conversion Agent shall be
fully authorized and protected in relying on any Officers Certificate delivered pursuant to Section 10(h) and any adjustment contained therein and the Conversion Agent shall not be deemed to have knowledge of any adjustment unless and
until it has received such certificate. The Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any Common Shares, or of any other securities or property, that may at the time be issued or
delivered with respect to any Convertible Preference Shares; and the Conversion Agent makes no representation with respect thereto. The Conversion Agent shall not be responsible for any failure of the Company to issue, transfer or deliver any Common
Shares pursuant to a the conversion of Convertible Preference Shares or to comply with any of the duties, responsibilities or covenants of the Company contained in this Section 10.

(j) Fractional Shares. No fractions of Common Shares will be issued to holders of the Convertible Preference Shares upon conversion. In lieu of
fractional shares otherwise issuable, holders will be entitled to receive an amount in cash equal to the fraction of a Common Share, calculated on an aggregate basis in respect of the Convertible Preference Shares being converted, multiplied by the
Closing Price of the Common Shares on the Trading Day immediately preceding the applicable Conversion Date.

Section 11.

Adjustment for Reorganization Events.

(a) Reorganization Events. In the event of:

(i) any consolidation, merger,
amalgamation, scheme of arrangement, other binding share exchange or reclassification involving the Company in which all or substantially all outstanding Common Shares are converted into or exchanged for cash, securities or other property of the
Company or another Person; or

(ii) the completion of any sale or other disposition in one transaction or a series of
transactions of all or substantially all the assets of the Company to another Person;



-23-



---

each of which is referred to as a Reorganization Event, each Convertible Preference
Share issued and outstanding immediately prior to such Reorganization Event will, without the consent of the holders of the Convertible Preference Shares, become convertible into the kind and amount of securities, cash and other property, if any
(the Exchange Property), receivable in such Reorganization Event (without any interest thereon, and, subject to any right of the Holder to receive Participating Dividends, without any right to dividends or distributions thereon
that have a record date that is prior to the applicable Conversion Date) per Common Share by a holder of Common Shares that is not a Person with which the Company effected such consolidation, merger, amalgamation, scheme of arrangement, other
binding share exchange or reclassification, or to which such sale or other disposition was made, as the case may be (each of the Company and any such other Person, a Constituent Person), or an Affiliate of a Constituent Person to
the extent such Reorganization Event provides for different treatment of Common Shares held by Affiliates and Non-Affiliates of the Company; provided that if the kind or amount of securities, cash and other property receivable upon such
Reorganization Event is not the same for each Common Share held immediately prior to such Reorganization Event by a Person other than a Constituent Person or an Affiliate thereof (due to elections or otherwise), then for the purpose of this
Section 11(a), the kind and amount of securities, cash and other property receivable upon such Reorganization Event will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Shares
(other than Constituent Persons and Affiliates thereof) that affirmatively make an election (or of all such holders if none make an election) (and if holders of Common Shares (other than Constituent Persons and their Affiliates) may elect the kind
and amount of securities, cash and other property so receivable, each Holder shall have the same election right with respect to the Exchange Property receivable upon conversion after the Reorganization Event, provided such Holder notifies the
Company of its election in writing prior to the Reorganization Event). On each Conversion Date following a Reorganization Event, the Conversion Rate then in effect will be applied to the Exchange Property received per Common Share, as determined in
accordance with this Section 11.

(b) Successive Reorganization Events.The above provisions of this Section 11 shall
similarly apply to successive Reorganization Events and the provisions of Section 10 shall apply to any securities of the Company (or any successor) received by the holders of the Common Shares in any such Reorganization Event.

(c) Reorganization Event Notice. The Company (or any successor) shall, within 20 days after the occurrence of any Reorganization Event,
provide written notice to the Holders of such occurrence of such event and of the kinds and amounts of the cash, securities or other property that constitutes the Exchange Property. Failure to deliver such notice shall not affect the operation of
this Section 11.

Section 12.

Voting Rights.

(a) General.The Holders shall not be entitled to vote on, consent to or take
any other action with respect to any matter, whether pursuant to this Certificate of Designations, the Bye-laws or otherwise, except as set forth in Section 12(b), 12(c) or 12(d) below or as required by Bermuda law.

(b) Special Voting Right.

(i) Voting Right. If and whenever dividends on the Convertible Preference Shares, or on any other class or series of Parity Dividend Shares, have not been paid in an aggregate amount equal, as to any particular class or series, to at
least six quarterly dividend periods, whether consecutive or not (a Nonpayment), (A) the Board of Directors shall resolve to increase the number of directors constituting the Board of Directors by two and nominate two
individuals as directors to fill such new vacancies and (B) the Holders, together with the holders of any and all classes and series of Parity Dividend Shares having like voting rights (i.e., being similarly entitled to vote
for two additional directors at such time) (the Holders and any such other holders, collectively, the Voting Holders), shall have the right, voting separately as a single class without regard to class or series (and with voting
rights allocated pro rata based on the liquidation preference of each such class or series), to the exclusion of the holders of Common Shares, to elect to the Board of Directors two additional directors from among such nominees, in the manner
provided in this Section 12(b). Each such director elected by the Voting Holders pursuant to this Section 12(b) is herein called a Preference Share Director. At no time shall the Board of Directors include more than two
Preference Share Directors.

(ii) Nomination. At any time when the Voting Holders are entitled to elect a Preference
Share Director pursuant to this Section 12(b), any one or more of the Holders holding at least a majority in aggregate Liquidation Preference of the Convertible Preference Shares then issued and outstanding and entitled to nominate under the
terms of such shares, and/or any one or more holders of any other class or series of Parity Dividend Shares having like voting rights then issued and outstanding, shall have the right to recommend individuals to the Company to serve as Preference
Share Directors. Such recommendations shall be in writing and shall be accompanied by a Director Acceptance Letter in the form attached hereto as Exhibit B (Director Acceptance Letter), from and signed by each such
recommended individual and such background and other information about each such individual as the Company may reasonably request to ensure compliance with applicable disclosure and other considerations pursuant to applicable law and customary
practice. The Board of Directors (excluding Preference Share Directors) will nominate the individuals so recommended for each Preference Share Director to be elected. The Board of Directors shall submit each recommended individual who it nominates
pursuant to this Section 12(b)(ii) to the Voting Holders for election as a Preference Share Director as provided below.



-25-



---

(iii) Election; Vacancy. The election of the Preference Share Directors by the
Voting Holders may take place at any general meeting of Members, or at any special meeting of Voting Holders held separately from other Members, or by means of a written resolution of the Voting Holders in lieu of a meeting thereof, in each case as
the Board of Directors may determine in its reasonable discretion. The Preference Share Directors shall be so elected by a plurality of the votes cast at the relevant meeting (or, if the election is effected by written resolution, by the Voting
Holders constituting a quorum, which shall also be the required voting threshold for purposes of such a written resolution), in each case whether or not the number of nominees exceeds the number of individuals to be elected. Each of the Preference
Share Directors elected hereunder shall serve as a director until the next annual general meeting of Members, or until the earlier of such time as he or she resigns, retires, dies or is removed or the special voting right pursuant to this
Section 12(b) terminates. The Board of Directors shall nominate individuals to succeed such individuals as the Preference Share Directors, in each case from among recommendations of the Voting Holders, all as provided in Section 12(b)(ii)
provided that such recommendations may include any such individuals whose service has ended and, in lieu of selecting nominees from any such recommendations, the Board of Directors may, in its discretion, nominate any or both of such
individuals whose service has ended (if willing to serve) for another term as a Preference Share Director. Each Preference Share Director shall agree, in the Director Acceptance Letter, to resign as such director when his or her term otherwise ends
pursuant to any removal or termination of the special voting right as provided in this Section 12(b). In case any vacancy in the office of a Preference Share Director occurs due to resignation, retirement, death or removal, the vacancy may be
filled by the written consent of the Preference Share Director remaining in office, or if none remains in office, in an election by Voting Holders as provided above for an initial election. All determinations and other actions to be made or taken by
the Board of Directors with regard to Preference Share Directors pursuant to this Section 12(b) shall be taken by the Board of Directors excluding the Preference Share Directors, who shall not be considered as Directors for the
purpose of such actions (including for the purpose of applying any quorum and voting requirements applicable to such actions). The Company will use reasonable best efforts to cause the individuals nominated to be elected as soon as practicable,
which will include for the avoidance of doubt, the initial election of any Preference Share Director, and the election of Preference Share Directors at any subsequent annual general meeting following the initial election of any Preference Share
Director. Subject to the foregoing, each of the Preference Share Directors shall have one vote as a director.

(iv)
Notice of Special Meeting; Quorum. The Company shall as soon as practicable, and in no case more than 30 days after the Board of Directors has selected the nominees as provided above, submit such nominees to the Voting Holders for
election either (i) at a general meeting of Members, (ii) at a special meeting of Voting Holders or (iii) by written resolution, as determined by the Board of Directors in its reasonable discretion. Notice for a special meeting of
Voting Holders may be given in the same manner as that provided in the Bye-laws for a special general meeting of the Members. If the Company fails to give notice of a meeting of Members or Voting Holders, or to seek a



-26-



---

written resolution of Voting Holders, to elect the Preference Share Directors within 30 days after the Board of Directors has selected the nominees for
such election as provided above, any Voting Holders entitled to recommend individuals for election as a Preference Share Director shall be entitled (at the Companys expense) to call such a meeting or seek such a written resolution to elect
such nominees selected by the Board of Directors, and for that purpose will have access to the register of Members of the Company. At any general meeting of Members, or any special meeting of Voting Holders, at which the Voting Holders have the
right to elect the Preference Share Directors, or at any adjournment thereof, the presence of at least two Persons holding or representing by proxy at least 50% in aggregate liquidation preference of the Convertible Preference Shares and all other
classes and series of Parity Dividend Shares having like voting rights, in each case at the time issued and outstanding, will be required to constitute a quorum for the election of any Preference Share Director. (Such quorum requirement shall also
apply with respect to any election of Preference Share Directors to be effected with the consent of Voting Holders given in a written resolution.) At any general meeting of Members or adjournment thereof, the absence of such a quorum of Voting
Holders will not prevent the election of directors other than the Preference Share Directors, and the absence of a quorum for the election of such other directors will not prevent the election of the Preference Share Directors. The Company may fix a
date as the record date for the purpose of determining the issued and outstanding preference shares of any class or series, and the Holders and other holders thereof entitled to elect the Preference Share Directors.

(v) Election to Board. For the avoidance of doubt, an individual who is elected a Preferred Share Director by the Voting Holders
pursuant to this Section 12(b) is not a director unless he or she is appointed by the Board of Directors, or elected by the Members, to the Board pursuant to the Bye-laws. Therefore, once a Preference Share Director is elected by the Voting
Holders pursuant to this Section 12(b), the Company shall use its reasonable best efforts to cause such Preference Share Director to be appointed by the Board, or elected by the Members, to the Board of Directors pursuant to the Bye-Laws as
soon as practical.

(vi) Termination; Removal.Whenever the Company has paid cumulative dividends in full for at
least four consecutive quarterly dividend periods on the Convertible Preference Shares and any other class or series of cumulative Parity Dividend Shares, and has paid cumulative dividends in full on any class or series of cumulative Parity Dividend
Shares, then the right of the Holders to elect the Preference Share Directors will cease (but subject always to the same provisions for the vesting of the special voting right in the case of any Nonpayment in respect of future Quarterly Dividend
Periods). The terms of office of the Preference Share Directors will immediately terminate, and the Board of Directors shall resolve to reduce the number of directors constituting the Board of Directors by two. In addition, any Preference Share
Director may be removed at any time with cause (as such term is defined in the Bye-laws) by Voting Holders holding a majority in aggregate Liquidation Preference of the aggregate liquidation preference of the Convertible Preference Shares, together
with all



-27-



---

classes and series of Parity Dividend Shares having like voting rights, voting separately as a single class without regard to class or series (and with
voting rights allocated pro rata based on the liquidation preference of each such class or series), to the exclusion of the holders of Common Shares, at a general meeting of Members or a special meeting of Voting Holders called by the Company
as provided in Section 12(b)(iv) above. In addition, if the Board of Directors determines in its discretion at any time that there is cause (as such term is defined in the Bye-laws), such directors term shall automatically terminate on
the date of the duly passed resolution of the Board of Directors. Upon the removal of any Preference Share Director, the vacancy shall be filled in the manner set forth in Section 12(b)(iii). Notwithstanding the foregoing, if at any time there
are no Convertible Preference Shares issued and outstanding, each Preference Share Directors term shall automatically terminate and no directors shall thereafter be appointed or elected pursuant to this Section 12.

(c) Senior Issuances; Adverse Changes. So long as any Convertible Preference Shares are issued and outstanding, the Company may not consummate any
action specified in clauses (i), (ii) or (iii) below without the vote or consent of the holders of a two-thirds majority in aggregate Liquidation Preference of the Convertible Preference Shares at the time issued and outstanding and
all voting or consenting as a single class, to the exclusion of the holders of Common Shares:

(i) any amendment, alteration
or repeal of any provision of the Memorandum of Association or Bye-laws or this Certificate of Designations that would alter or change the voting powers, preferences or special rights of the Convertible Preference Shares so as to affect them
adversely;

(ii) any authorization or creation of, or increase in the authorized amount of, any Senior Shares;

(iii) any consolidation, merger, amalgamation, scheme of arrangement, other binding share exchange or reclassification involving the
Company, except that, subject to applicable law, Holders of Convertible Preference Shares will have no right to vote or consent under this clause (iii) (or under clause (i) above) by reason of any such transaction if (A) the
Convertible Preference Shares remain issued and outstanding or, in the case of any such transaction with respect to which the Company is not the surviving or resulting issuer, are converted into or exchanged for preferred securities of the surviving
or resulting entity or its ultimate parent (provided that such entity is an entity organized and existing under the laws of Bermuda, the United States of America, any state thereof or the District of Columbia or any jurisdiction in the
European Economic Area, and is a corporation for U.S. federal income tax purposes (or if such entity is not a corporation for such purposes, the Company receives an opinion of nationally recognized counsel experienced in such matters to the effect
that Holders will be subject to tax for U.S. federal income tax purposes with respect to such new preferred securities after such transaction in the same amount, at the same time and otherwise in the same manner as would have been the case under the
Convertible Preference Shares prior to such



-28-



---

transaction)), and (B) the Convertible Preference Shares remaining issued and outstanding or such other preferred securities, as the case may be, have
such rights, preferences, privileges and voting powers, taken as a whole, as are not less favorable to the holders thereof than the rights, preferences, privileges and voting powers of the Convertible Preference Shares, taken as a whole;

provided,however, that (1) any increase in the amount of the authorized or issued, or any creation of, Convertible Preference Shares or any
authorization, issuance or creation of any securities convertible into, or exercisable or exchanged for, Convertible Preference Shares or (2) any increase in the amount of the authorized or issued, or any creation of, any other preference
shares ranking equally with or junior to the Convertible Preference Shares with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and the distribution of assets upon the Companys liquidation,
dissolution or winding up, or any authorization, issuance or creation of any securities convertible into, or exercisable or exchangeable for, any such other preference shares, in each case (1) and (2) will not be deemed to adversely affect
the voting powers, preferences or special rights of the Convertible Preference Shares and Holders will have no right under this Section 12(c) to vote on or consent to any such increase, authorization, issuance or creation.

If the Holders are entitled to vote on or consent to a specified action pursuant to this Section 12(c), the Company may call a meeting of the
Holders for the purpose of such vote or, in its discretion, may instead seek the consent of the Holders in a written resolution. Any such vote may be held at a general meeting of the Members, or at a special meeting of the Holders and such other
holders, as the Company may determine in its discretion. The Company may fix a date as the record date for the purpose of determining the issued and outstanding Convertible Preference Shares, and the Holders entitled to vote on or consent to any
such specified action. At any meeting of Members or Holders where such vote is to occur (or for any consent by written resolution), the necessary quorum for such vote (or consent) shall be at least two Persons holding or representing by proxy at
least 50% in aggregate liquidation preference of the Convertible Preference Shares entitled to vote on the relevant specified action.

If
the Holders of Convertible Preference Shares are entitled to vote on or take any action with respect to any matter, the Board of Directors may, in its discretion, determine that such vote or other action be taken by means of a written resolution of
the Holders entitled to take such action. Unless authorized by the Board of Directors, the Holders shall have no right to act by written resolution, notwithstanding any provision of the Bye-laws, this Certificate of Designations or otherwise.

(d) Vote with Common Shares. The Holders:

(i) shall be entitled to vote with the holders of the Common Shares on all matters submitted for a vote of holders of Common Shares,
voting together with the holders of Common Shares (and not as a separate class or series), which shall include the right of the Holders to vote together with the holders of the Common Shares for the election of directors at any annual general
meeting,



-29-



---

(ii) shall be entitled to a number of votes equal to the number of votes to which Common
Shares issuable upon conversion of such Convertible Preference Shares would have been entitled if such Common Shares had been issued and outstanding at the time of the applicable vote and related record date, and

(iii) shall be entitled to notice of any Members meeting in accordance with the Bye-laws.

(e) No Vote if Redemption. No vote or consent of the Holders shall be required pursuant to Section 12(b), (c) or (d) if, at or
prior to the time when the act with respect to which such vote or consent would otherwise be required shall be effected, the Company shall have redeemed or shall have called for redemption all issued and outstanding Convertible Preference Shares,
with proper notice and sufficient funds having been set aside for such redemption, in each case pursuant to Section 6 above.

Section 13.

Preemption.

The Holders shall not have any rights of preemption with regard to any capital shares (including common shares and preferred shares).

Section 14.

Payments and Notices.

(a) Payment. Any payment due by the Company with respect to dividends, redemptions, fractional shares or other amounts on a day that is not a
Business Day may be made on the next succeeding Business Day with the same force and effect as if made on the original due date, and without any interest due to any delay in payment.

(b) Notices. Any notices, deliveries or other actions required or permitted to be given, made or taken by the Company or any Holder hereunder on a
particular day may be effected on the next succeeding Business Day with the same force and effect as if effected on the particular day.

Section 15.

Rank.

Notwithstanding anything set forth in the Memorandum of Association, the Bye-laws or this Certificate of Designations to the contrary, the Board of Directors or any duly authorized committee thereof, without the vote
of the Holders, may authorize and issue new or additional Junior Shares and Parity Shares. Neither the Board of Directors nor any committee thereof shall have the authority to create or issue any Senior Shares without the affirmative vote (or
written consent) of the holders of a majority in aggregate Liquidation Preference of the outstanding Convertible Preference Shares, voting (or consenting) separately as a class, as provided in Section 12(c).

Section 16.

Repurchase.

Subject to the limitations imposed herein and applicable Bermuda law, the Company may
purchase Convertible Preference Shares from time to time to such extent, in such manner and upon such terms as the Board of Directors or any duly authorized committee thereof may determine; provided, however, that the Company shall not
use any of its funds for any such purchase when there are reasonable grounds to believe that the Company is, or after such purchase would be, unable to pay its liabilities as they become due; and provided further that in the event that the
Company beneficially owns any Convertible Preference Shares, the Company will procure that voting rights in respect of such Convertible Preference Shares are not exercised.

Section 17.

Unissued or Reacquired Shares.

Convertible Preference Shares not issued or that have been issued and converted, redeemed or otherwise purchased or acquired by the Company shall be
restored to the status of authorized but unissued preference shares without designation as to series, until such shares are once more designated as part of a particular series by the Board of Directors.

Section 18.

No Sinking Fund.

Convertible Preference Shares are not subject to the operation of a sinking fund.

Section 19.

Reservation of
Common Shares.

Common Shares as shall from time to time be issuable upon the conversion of all the Convertible Preference Shares then issued and outstanding. For purposes of this Section 19(a), the number of Common Shares that shall be deliverable upon the
conversion of all issued and outstanding Convertible Preference Shares shall be computed as if at the time of computation all such outstanding shares were held by a single Holder.



-31-



---

(b) Use of Acquired Shares.Notwithstanding the foregoing, the Company shall be entitled to
deliver upon conversion of Convertible Preference Shares, as herein provided, Common Shares acquired by the Company (in lieu of the issuance of authorized and unissued Common Shares), so long as any such acquired shares are free and clear of all
liens, charges, security interests or encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(c) Free and Clear Delivery. All Common Shares delivered upon conversion of the Convertible Preference Shares shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security
interests and other encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(d)
Compliance with Law.Prior to the delivery of any securities that the Company shall be obligated to deliver upon conversion of the Convertible Preference Shares, the Company shall use its reasonable best efforts to comply with all laws and
regulations thereunder requiring the approval of such delivery by any Regulatory Entities.

(e) Listing. The Company hereby
covenants and agrees that, if at any time the Common Shares shall be listed on the New York Stock Exchange or any other securities exchange or quotation system, the Company will, if permitted by the rules of such exchange or quotation system, list
and keep listed, so long as the Common Shares shall be so listed on such exchange or quotation system, all the Common Shares issuable upon conversion of the Convertible Preference Shares.

Section 20.

Transfer Agent, Conversion Agent, Registrar and Paying
Agent.

The duly appointed Transfer Agent, Conversion Agent, Registrar and paying agent for the Convertible Preference Shares shall be
Computershare Trust Company, N.A. The Company may, in its sole discretion, remove the Transfer Agent in accordance with the agreement between the Company and the Transfer Agent; provided that the Company shall appoint a successor transfer
agent who shall accept such appointment prior to the effectiveness of such removal. Upon any such removal or appointment, the Company shall send notice thereof by first-class mail, postage prepaid, to the Holders (or otherwise pursuant to any
applicable procedures of a Depositary).

Section 21.

Replacement Certificates.

(a) Mutilated, Destroyed, Stolen and Lost
Certificates.If physical certificates are issued, the Company shall replace any mutilated certificate at the Holders expense upon surrender of that certificate to the Transfer Agent. The Company shall replace certificates that become
destroyed, stolen or lost at the Holders expense upon delivery to the Company and the Transfer Agent of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with any indemnity that may be required by the
Transfer Agent and the Company.



-32-



---

(b) Certificates Following Conversion.If physical certificates are issued, the Company shall not
be required to issue any certificates representing the applicable Convertible Preference Shares on or after the applicable Conversion Date. In place of the delivery of a replacement certificate following the applicable Conversion Date, the Transfer
Agent, upon delivery of the evidence and indemnity described in Section 21(a), shall deliver the Common Shares pursuant to the terms of the Convertible Preference Shares formerly evidenced by the certificate.

(c) Legends.Certificates for Convertible Preference Shares and any Common Shares issued on conversion thereof may have notations, legends
or endorsements required by law, stock exchange rules, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company).

Section 22.

Form.

(a) Global Preference Shares.Convertible Preference Shares may, at the Companys option, in its sole
discretion, be issued in the form of one or more permanent global shares of Convertible Preference Shares in definitive, fully registered form with a global legend in substantially the form attached hereto as Exhibit A (each, a Global
Preference Share), which is hereby incorporated in and expressly made a part of this Certificate of Designations. The Global Preference Shares may have notations, legends or endorsements required by law, stock exchange rules, agreements to
which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). The aggregate number of shares represented by each Global Preference Share may from time to time
be increased or decreased by adjustments made on the records of the Registrar and the Depositary or its nominee as hereinafter provided. Global Preference Shares shall be registered in the name of the Depositary, which shall be the Holder of such
shares. This Section 22(a) shall apply only to a Global Preference Share deposited with or on behalf of the Depositary.

(b)
Delivery to Depositary.If Global Preference Shares are issued, the Company shall execute and the Registrar shall, in accordance with this Section 22, countersign and deliver initially one or more Global Preference Shares that
(i) shall be registered in the name of a nominee of the Depositary and (ii) shall be delivered by the Registrar to the Depositary or pursuant to instructions received from the Depositary or held by the Registrar as custodian for the
Depositary pursuant to an agreement between the Depositary and the Registrar.

(c) Agent Members.If Global Preference Shares are
issued, members of, or participants in, the Depositary (Agent Members) shall have no rights under this Certificate of Designations with respect to any Global Preference Share held on their behalf by the Depositary or by the
Registrar as the custodian of the Depositary or under such Global Preference Shares,



-33-



---

and the Depositary may be treated by the Company, the Registrar and any agent of the Company or the Registrar as the absolute owner of such Global Preference
Share for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Registrar or any agent of the Company or the Registrar from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of the Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Preference Shares.
If Global Preference Shares are issued, the Depositary may grant proxies or otherwise authorize any Person to take any action that a Holder is entitled to take pursuant to the Convertible Preference Shares, this Certificate of Designations or the
Bye-laws.

(d) Physical Certificates.Owners of beneficial interests in any Global Preference Shares shall not be entitled to
receive physical delivery of certificated Convertible Preference Shares, unless (x) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for the Global Preference Shares and the Company does not
appoint a qualified replacement for the Depositary within 90 days, (y) the Depositary ceases to be a clearing agency registered under the Exchange Act and the Company does not appoint a qualified replacement for the Depositary
within 90 days or (z) the Company decides to discontinue the use of book-entry transfer through the Depositary. In any such case, the Global Preference Shares shall be exchanged in whole for definitive Convertible Preference Shares in
registered form, with the same terms and of an equal aggregate Liquidation Preference. Such definitive Convertible Preference Shares shall be registered in the name or names of the Person or Persons specified by the Depositary in a written
instrument to the Registrar.

(e) Signature.An Officer shall sign any Global Preference Share for the Company, in accordance with
the Companys Bye-laws and applicable law, by manual or facsimile signature. If an Officer whose signature is on a Global Preference Share no longer holds that office at the time the Transfer Agent countersigned the Global Preference Share, the
Global Preference Share shall be valid nevertheless. A Global Preference Share shall not be valid until an authorized signatory of the Transfer Agent manually countersigns the Global Preference Share. Each Global Preference Share shall be dated the
date of its countersignature.

Section 23.

Taxes.

(a) Transfer Taxes.The Company shall pay any and all share transfer, documentary,
stamp and similar taxes that may be payable in respect of any issuance or delivery of Convertible Preference Shares or Common Shares or other securities issued on account of Convertible Preference Shares pursuant hereto or certificates representing
such shares or securities. The Company shall not, however, be required to pay any such tax that may be payable in respect of any transfer involved in the issuance or delivery of Convertible Preference Shares, Common Shares or other securities in a
name other than that in which the Convertible Preference Shares with respect to which such shares or other securities are issued or delivered were registered, or in respect of any payment to any Person other than a payment to the



-34-

issuance, delivery or payment has paid to the Company the amount of any such tax or has established, to the satisfaction of the Company, that such tax has been paid or is not payable.

(b) Withholding. All payments and distributions (or deemed distributions) on the Convertible Preference Shares (and on the Common Shares received
upon their conversion) shall be subject to withholding and backup withholding of tax to the extent required by law, subject to applicable exemptions, and amounts withheld, if any, shall be treated as received by Holders.

Section 24.

All notices referred to herein shall be in writing, and, unless otherwise specified herein, all notices hereunder shall be deemed to
have been given upon the earlier of receipt thereof or three Business Days after the mailing thereof if sent by registered or certified mail (or by first class mail if the same shall be specifically permitted for such notice under the terms of this

may be, shall have designated by notice similarly given. Notwithstanding the foregoing, any notice given by the Company to Holders in respect of a Global Preference Share pursuant to the applicable procedures of the Depositary shall be deemed to
have been given effectively when so given.

Section 25.
