Consent

WHEREAS, the Corporation and the Shareholder are party to that certain Securities Purchase Agreement (the “SPA”), dated as of March 14, 2019;

WHEREAS, pursuant to the SPA, the Shareholder purchased 50,000 Series 6 Shares having the terms set forth in the articles of amendment designating the Series 6 Shares (the “Series 6 Articles of Amendment”), dated as of March 14, 2019;

WHEREAS, the Transactions constitute a Fundamental Change pursuant to the SPA and the Series 6 Articles of Amendment;

WHEREAS, pursuant to Section 4.12 of the SPA, the Corporation has agreed that it shall not become party to a transaction that constitutes a Fundamental Change other than a Qualifying Transaction;

WHEREAS, pursuant to the terms of the SPA and the Series 6 Articles of Amendment, a Qualifying Transaction is a Fundamental Change that (i) with regard to which the holder of Series 6 Shares is entitled to receive, directly or indirectly, in respect of its Series 6 Shares, in connection with the consummation of such transaction (including pursuant to the conversion of the Series 6 Shares (without regard to limitations or restrictions on conversion) or the purchase or exchange of such Series 6 Shares in a tender or exchange offer), consideration consisting solely of cash, equity securities that are immediately tradable on a national securities exchange and that have (or the equity securities of the predecessor of the issuer of such equity securities have) an average trading volume per trading day over the thirty (30) trading days preceding public announcement of such transaction at least equal to that of the Class A Shares over the thirty (30) trading days preceding public announcement of such transaction, or a combination of cash and such equity consideration (collectively, “qualifying consideration”), which qualifying consideration is in an amount per outstanding Series 6 Share that is at least equal to the Base Liquidation Preference of such Series 6 Share plus all accrued but unpaid dividends thereon (with the value of any non-cash consideration being the Fair Market Value of such non-cash consideration at the time of signing of the definitive transaction agreement for the applicable transaction) or (ii) that is otherwise consented to by the holders of two-thirds of the outstanding Series 6 Shares;

NOW, THEREFORE, BE IT RESOLVED, that the Shareholder hereby reaffirms that it consents to the Corporation’s entry into the Transaction Agreement and the Transactions for all purposes pursuant to the Series 6 Articles of Amendment and the SPA and reaffirms that the Transactions shall be a “Fundamental Change” as defined in the SPA but shall not be a “Specified Event” or a “Qualifying Transaction” for purposes of the SPA or the Series 6 Articles of Amendment.

Disposition Event

WHEREAS, pursuant to the SPA and Section 5(f)(iv) of the Series 6 Articles of Amendment, the Transactions would constitute a Disposition Event, and as a result the Series 6 Shares would thus be entitled to Reference Property received upon the occurrence of such Disposition Event by a holder of Class A Shares holding, immediately prior to the Transactions, a number of Class A Shares equal to the Conversion Amount.

NOW, THEREFORE, BE IT RESOLVED, that, notwithstanding any provisions to the contrary in the SPA or the Series 6 Articles of Amendment, the Shareholder hereby agrees that the Transactions shall not constitute a Disposition Event.

Exhibit C

Certificate of Designation of Series 6 Convertible Preferred Stock

Exhibit C

AMENDED AND RESTATED

DESIGNATION
OF
SERIES 6 CONVERTIBLE PREFERRED STOCK
OF
STAGWELL INC.

SECTION 1. Designation and Amount. The designation of this series of Preferred Stock is “Series 6 Convertible Preferred Stock” (the “Series 6 Preferred Shares”), no par value, and the number of shares constituting such series is Fifty Thousand (50,000). Subject to the Certificate of Incorporation, such number of shares may be increased or decreased by resolution of the Board of Directors; provided, however, that no decrease shall reduce the number of shares of Series 6 Preferred Shares to less than the number of shares then issued and outstanding plus the number of shares issuable upon exercise of outstanding rights, options or warrants or upon conversion of outstanding securities issued by the Corporation.

SECTION 2. Dividends.

(a) Participating Dividends.

(i) Each holder of issued and outstanding Series 6 Preferred Shares will be entitled to receive, when, as and if declared by the Board of Directors, out of funds legally available for the payment of dividends for each Series 6 Preferred Share, dividends of the same type as any dividends or other distribution, whether in cash, in kind or in other property, payable or to be made on outstanding Class A Subordinate Voting Shares of the Corporation (the “Class A Shares”), in an amount equal to the amount of such dividends or other distribution as would be made on the number of Class A Shares into which such Series 6 Preferred Shares could be converted on the applicable record date for such dividends or other distribution on the Class A Shares, without giving effect to the limitations set forth in SECTION 6(b) after aggregating all shares held by the same holder (the “Participating Dividends”) and disregarding any rounding for fractional amounts; provided, however, that notwithstanding the above, the holders of Series 6 Preferred Shares shall not be entitled to receive any dividends or distributions for which an adjustment to the Conversion Price (as defined below) shall be made pursuant to SECTION 6(f)(i)(A) or SECTION 6(f)(ii) (and such dividends or distributions that are not payable to the holders of Series 6 Preferred Shares as a result of this proviso shall not be deemed to be Participating Dividends).

(ii) Participating Dividends are payable at the same time as and when such dividends or other distributions on the Class A Shares are paid to the holders of Class A Shares and are payable to holders of record of Series 6 Preferred Shares on the record date for the corresponding dividend or distribution on the Class A Shares.

(b) Additional Dividends.

(i) Following the occurrence of a Specified Event, each holder of issued and outstanding Series 6 Preferred Shares will be entitled to receive, when, as and if declared by the Board of Directors, out of funds legally available for the payment of dividends for each Series 6 Preferred Share, with respect to each Dividend Period, dividends at a rate per annum equal to the Additional Rate multiplied by the Base Liquidation Preference per Series 6 Preferred Share (the “Additional Dividends” and, together with Participating Dividends, the “Dividends”). Any Additional Dividends payable pursuant to this SECTION 2(b) shall be in addition to any Participating Dividends, as applicable, payable pursuant to SECTION 2(a) hereof.

(ii) Additional Dividends will accrue on a daily basis and be cumulative from the date on which a Specified Event occurs and are payable in arrears on each Dividend Payment Date.

(iii) Additional Dividends in respect of any Dividend Period shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of Additional Dividends payable for any Dividend Period shorter or longer than a full quarterly Dividend Period will be computed on the basis of a 360-day year consisting of twelve 30-day months.

(iv) Additional Dividends that are declared and payable on a Dividend Payment Date will be paid to the holders of record of Series 6 Preferred Shares as they appear in the records of the Corporation at the close of business on the 15th day of the calendar month prior to the month in which the applicable Dividend Payment Date falls, provided that Additional Dividends payable upon redemption or conversion of Series 6 Preferred Shares will be payable to the holder of record on the Redemption Date or the Conversion Date, as applicable. Any payment of an Additional Dividend will first be credited against the earliest accumulated but unpaid Additional Dividend due with respect to each share that remains payable.

(v) Additional Dividends are payable only in cash. Additional Dividends will accrue and cumulate whether or not the Corporation has earnings or profits, whether or not there are funds legally available for the payment of Additional Dividends and whether or not Additional Dividends are declared.

(vi) After a Specified Event has occurred and while any Series 6 Preferred Shares remain outstanding, unless all Additional Dividends accrued to the end of all completed Dividend Periods have been paid in full, neither the Corporation nor any of its subsidiaries may (A) declare, pay or set aside for payment any dividends or distributions on any Junior Securities or (B) repurchase, redeem or otherwise acquire any Junior Securities.

(vii) The provisions of SECTION 2(b)(vi) shall not prohibit:

(A) the repurchase, redemption, retirement or other acquisition of vested or unvested Common Shares held by any future, present or former officer, director, employee, manager or consultant (or their respective permitted transferees) of the Corporation or any subsidiary of the Corporation pursuant to any equity incentive grant, plan, program or arrangement, any severance agreement or any stock subscription or equityholder agreement, in each case solely to the extent required by the terms thereof;

(B) payments made or expected to be made by the Corporation in respect of withholding or similar taxes payable in connection with the exercise or vesting of Common Shares or Class A Equivalents (as defined below) by any future, present or former officer, director, employee, manager or consultant (or their respective permitted transferees) of the Corporation or any subsidiary of the Corporation and repurchases or withholdings of Common Shares or Class A Equivalents in connection with any exercise or vesting of Common Shares or Class A Equivalents if such Common Shares or Class A Equivalents represent all or a portion of the exercise price of, or withholding obligation with respect to, such Common Shares or Class A Equivalents;

C-2

(C) cash payments made in lieu of issuing fractional Common Shares in connection with the exercise or vesting of Common Shares or Class A Equivalents;

(D) payments arising from agreements of the Corporation or a subsidiary of the Corporation providing for adjustment of purchase price, deferred consideration, earn outs or similar obligations, in each case incurred in connection with the purchase or investment by the Corporation or a subsidiary of the Corporation of or in assets or capital stock of a third party; or

(E) payments or distributions made pursuant to any plan or proposal for the liquidation or dissolution of the Corporation or pursuant to any decree or order for relief or made by any custodian of the Corporation in connection with any voluntary case or proceeding under Title 11 of the U.S. Code or any similar federal, state or non-U.S. law for the relief of debtors.

(c) The Corporation shall pay Dividends (less any tax required to be deducted and withheld by the Corporation), except in case of redemption or conversion in which case payment of Dividends shall be made on surrender of the certificate, if any, representing the Series 6 Preferred Shares to be redeemed or converted, by electronic funds transfer or by sending to each holder of Series 6 Preferred Shares a check for such Dividends payable to the order of such holder or, in the case of joint holders, to the order of all such holders failing written instructions from them to the contrary or in such other manner, not contrary to applicable law, as the Corporation shall reasonably determine. The making of such payment or the posting or delivery of such check on or before the date on which such Dividend is to be paid to a holder shall be deemed to be payment and shall satisfy and discharge all liabilities for the payment of such Dividends to the extent of the sum represented thereby (plus the amount of any tax required to be and in fact deducted and withheld by the Corporation from the related Dividends as aforesaid and remitted to the proper taxing authority) unless such check is not honored when presented for payment. Subject to applicable law, Dividends which are represented by a check which has not been presented to the Corporation’s bankers for payment or that otherwise remain unclaimed for a period of six years from the date on which they were declared to be payable shall be forfeited to the Corporation.

(d) Holders of the Series 6 Preferred Shares are not entitled to any dividend, whether payable in cash, in kind or other property, in excess of the Participating Dividends and, if applicable, the Additional Dividends, as provided in this SECTION 2.

C-3

SECTION 3. Liquidation Preference.

(a) Upon any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, each Series 6 Preferred Share entitles the holder thereof to receive and to be paid out of the assets of the Corporation available for distribution, before any distribution or payment may be made to a holder of any Class A Shares, any Class B Shares of the Corporation (the “Class B Shares”), any Class C Shares of the Corporation (“Class C Shares”) or any other shares ranking junior as to capital to the Series 6 Preferred Shares, an amount per Series 6 Preferred Share equal to the greater of (i) the Base Liquidation Preference (as defined below), as increased by the Accretion Rate (as defined below) from the most recent Quarterly Compounding Date to the date of such liquidation, dissolution or winding up (without duplication of changes to the Base Liquidation Preference as provided for in SECTION 3(b)) plus any accrued but unpaid Dividends with respect thereto, and (ii) an amount equal to the amount the holders of the Series 6 Preferred Shares would have received per Series 6 Preferred Share upon liquidation, dissolution or winding up of the Corporation had such holders converted their Series 6 Preferred Shares into Class A Shares immediately prior thereto, without giving effect to the limitations set forth in SECTION 6(b) and disregarding any rounding for fractional amounts (the greater of the amount in clause (i) and clause (ii), the “Liquidation Preference”). Notwithstanding the foregoing or anything in this Designation to the contrary, immediately prior to and conditioned upon the consummation of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, if the amount set forth in clause (i) above is greater than the amount set forth in clause (ii) above, any holder of outstanding Series 6 Preferred Shares shall have the right to convert its Series 6 Preferred Shares into Class A Shares by substituting the Fair Market Value of a Class A Share for the then-applicable Conversion Price (as defined below) and without giving effect to the limitations set forth in SECTION 6(b) and disregarding any rounding for fractional amounts.

(b) The “Base Liquidation Preference” per Series 6 Preferred Share shall initially be equal to the Original Purchase Price. From and after the one year anniversary of the Series 6 Original Issuance Date through March 14, 2024, the Base Liquidation Preference of each Series 6 Preferred Share shall increase on a daily basis, on the basis of a 360-day year consisting of twelve 30-day months, at a rate of 8.0% per annum (the “Accretion Rate”) of the then-applicable Base Liquidation Preference, the amount of which increase shall compound quarterly on each March 31, June 30, September 30 and December 31 (each, a “Quarterly Compounding Date”), following which the Accretion Rate will decrease to 0% per annum and the Base Liquidation Preference per Series 6 Preferred Share will not increase during any period subsequent to March 14, 2024. The Base Liquidation Preference shall be proportionally adjusted for any stock dividends, splits, combinations and similar events on the Series 6 Preferred Shares. For the avoidance of doubt, from and after the Series 6 Original Issuance Date until the one year anniversary of the Series 6 Original Issuance Date, the Accretion Rate will be 0% per annum and the Base Liquidation Preference per Series 6 Convertible Preferred Share will not increase during such period.

(c) After payment to the holders of the Series 6 Preferred Shares of the full Liquidation Preference to which they are entitled, the Series 6 Preferred Shares as such will have no right or claim to any of the assets of the Corporation.

(d) The value of any property not consisting of cash that is distributed by the Corporation to the holders of the Series 6 Preferred Shares will equal the Fair Market Value thereof on the date of distribution.

(e) For the purposes of this SECTION 3, a Fundamental Change (in and of itself) shall not be deemed to be a liquidation, dissolution or winding up of the Corporation subject to this SECTION 3 (it being understood that an actual liquidation, dissolution or winding up of the Corporation in connection with a Fundamental Change will be subject to this SECTION 3).

C-4

SECTION 4. Voting Rights.

(a) Holders of the Series 6 Preferred Shares shall not be entitled as such, except as required by law or as expressly set forth in this Certificate of Designation, to receive notice of or to attend any meeting of the stockholders of the Corporation or to vote at any such meeting but shall be entitled to receive notice of meetings of stockholders of the Corporation called for the purpose of authorizing the dissolution of the Corporation or the sale of all or substantially all of its assets.

(b) For so long as any Series 6 Preferred Shares are outstanding, in addition to any vote or consent of stockholders required by applicable law or by the Certificate of Incorporation, the Corporation shall not, and shall cause its subsidiaries not to, without the affirmative approval of the holders of a majority of the Series 6 Preferred Shares (by vote or consent):

(i) effect, permit, approve, ratify or validate (including, but not limited to, by merger or consolidation or otherwise by operation of law):

(A) an increase or decrease of the maximum number of authorized Series 6 Preferred Shares, or an increase of the maximum number of authorized shares of a class or series having rights or privileges equal or superior to the Series 6 Preferred Shares;

(B) an exchange, replacement, reclassification or cancellation of all or part of the Series 6 Preferred Shares;

(C) an amendment, alteration, change or repeal of any of the rights, privileges, preferences, powers, restrictions or conditions of the Series 6 Preferred Shares and, without limiting the generality of the foregoing, (i) a repeal or change of the rights to accrued dividends or the rights to cumulative dividends of the Series 6 Preferred Shares that is adverse, (ii) an amendment, alteration, repeal or change of redemption rights of the Series 6 Preferred Shares that is adverse, (iii) a reduction or repeal of a dividend preference or a liquidation preference of the Series 6 Preferred Shares, or (iv) an amendment, alteration, repeal or change of conversion privileges, options, voting, transfer or pre-emptive rights, or rights to acquire securities of a corporation, or sinking fund provisions of the Series 6 Preferred Shares that is adverse;

(D) an amendment, alteration or change of the rights or privileges of any class or series of shares having rights or privileges equal or superior to the Series 6 Preferred Shares;

(E) the creation or authorization of a new class or series of shares having rights or privileges equal or superior to the Series 6 Preferred Shares;

C-5

(F) an exchange or the creation of a right of exchange of all or part of the shares of another class or series into the Series 6 Preferred Shares;

(G) any constraint on the issuance, transferability or ownership of the Series 6 Preferred Shares or the change or removal of such constraint; or

(ii) effect, permit, approve, ratify or validate any of the foregoing with respect to the Series 6 Preferred Units (as defined in the A&R OpCo LLC Agreement) (including, but not limited to by merger or consolidation or otherwise by operation of law) by voting any of the limited liability company interests of Midas OpCo LLC issued to the Corporation or otherwise.

(c) The approval of the holders of the Series 6 Preferred Shares with respect to any and all matters referred to in this Designation may be given by the affirmative vote, given in person or by proxy at any meeting called for such purpose, or by written consent, of the holders of at least a majority of the Series 6 Preferred Shares issued and outstanding, voting as a separate class.

SECTION 5. Purchase for Cancellation. Subject to such provisions of the General Corporation Law of the State of Delaware as may be applicable, the Corporation may at any time or times purchase (if obtainable) for cancellation all or any part of the Series 6 Preferred Shares outstanding from time to time: (a) through the facilities of any Exchange or market on which the Series 6 Preferred Shares are listed, (b) by invitation for tenders addressed to all the holders of record of the Series 6 Preferred Shares outstanding, or (c) in any other manner, in each case at the lowest price or prices at which, in the opinion of the Board of Directors, such shares are obtainable.

SECTION 6. Conversion.

Each Series 6 Preferred Share is convertible into Class A Shares as provided in this SECTION 6.

(a) Conversion at the Option of Holders of Series 6 Preferred Shares. Subject to SECTION 6(b), each holder of Series 6 Preferred Shares is entitled to convert, in whole or in part at any time and from time to time, at the option and election of such holder upon receipt of all antitrust approvals required in connection with such conversion (or the lapse of any applicable waiting period relating to such required antitrust approvals), any or all outstanding Series 6 Preferred Shares held by such holder into a number of duly authorized, validly issued, fully paid and nonassessable Class A Shares equal to the number (the “Conversion Amount”) determined by dividing (i) the Base Liquidation Preference (as adjusted pursuant to SECTION 3(b) to the date immediately preceding the Conversion Date (as defined below)) for each Series 6 Preferred Share to be converted by (ii) the Conversion Price in effect at the time of conversion. The “Conversion Price” initially is $5.00 per share, as adjusted from time to time as provided in SECTION 6(f). In order to convert the Series 6 Preferred Shares into Class A Shares, the holder must surrender the certificates representing such Series 6 Preferred Shares, accompanied by transfer instruments satisfactory to the Corporation, free of any adverse interest or liens at the office of the Corporation’s transfer agent for the Series 6 Preferred Shares, together with written notice that such holder elects to convert all or such number of shares represented by such certificates as specified therein. With respect to a conversion pursuant to this SECTION 6(a), the date of receipt of such certificates, together with such notice and such other information or documents as may be required by the Corporation (including any certificates delivered pursuant to SECTION 6(b)), by the transfer agent or the Corporation will be the date of conversion (the “Conversion Date”) and the Conversion Date with respect to a conversion pursuant to SECTION 6(c) will be as provided in such section.

C-6

(b) Limitations on Conversion. Notwithstanding SECTION 6(a) or SECTION 6(c) but subject to SECTION 8, the Corporation shall not effect any conversion of the Series 6 Preferred Shares or otherwise issue Class A Shares pursuant to SECTION 6(a) or SECTION 6(c), and no holder of Series 6 Preferred Shares will be permitted to convert Series 6 Preferred Shares into Class A Shares if, and to the extent that, following such conversion, either (i) such holder’s aggregate voting power on a matter being voted on by holders of Class A Shares would exceed 19.9% of the Maximum Voting Power (as defined below) or (ii) such holder would Beneficially Own more than 19.9% of the then outstanding Common Shares; provided, however, that such conversion restriction shall not apply to any conversion in connection with and subject to completion of (A) a public sale of the Class A Shares to be issued upon such conversion, if following consummation of such public sale such holder will not Beneficially Own in excess of 19.9% of the then outstanding Class A Shares or (B) a bona fide third party tender offer for the Class A Shares issuable thereupon. For purposes of the foregoing sentence, the number of Class A Shares Beneficially Owned by a holder shall include the number of Class A Shares issuable upon conversion of the Series 6 Preferred Shares with respect to which a conversion notice has been given, but shall exclude the number of Class A Shares which would be issuable upon conversion or exercise of the remaining, unconverted portion of the Series 6 Preferred Shares and any Alternative Preference Shares Beneficially Owned by such holder. Upon the written request of the holder, the Corporation shall within two (2) Business Days confirm in writing (which may be by email) to any holder the number of Class A Shares, Class B Shares and Class C Shares then outstanding. In connection with any conversion and as a condition to the Corporation effecting such conversion, upon request of the Corporation, a holder of Series 6 Preferred Shares shall deliver to the Corporation a certificate, signed by a duly authorized officer of such holder, no less than twelve (12) Business Days prior to the applicable conversion, certifying that, after giving effect to such conversion, (i) such holder’s aggregate voting power on a matter being voted on by holders of Class A Shares will not exceed 19.9% of the Maximum Voting Power or (ii) such holder will not Beneficially Own more than 19.9% of the then outstanding Common Shares. For purposes hereof, “Maximum Voting Power” means, at the time of determination of the Maximum Voting Power, the total number of votes which may be cast by all shares of the Corporation’s capital on a matter subject to the vote of the Common Shares and any other securities that constitute Voting Stock voting together as a single class and after giving effect to any limitation on voting power set forth herein and the Certificate of Incorporation, the certificate of designation or other similar document governing other Voting Stock. For purposes of this SECTION 6(b), the aggregate voting power and Beneficial Ownership of Common Shares held by the Affiliates of a holder shall be attributed to such holder.

C-7

(c) Conversion at the Option of the Corporation. Subject to SECTION 6(b) and SECTION 8, at the Corporation’s option and election and upon its compliance with this SECTION 6(c), and in the case of the Investor and any Permitted Transferee upon receipt of all antitrust approvals required in connection with such conversion (or the lapse of any applicable waiting period relating to such required antitrust approvals), all outstanding Series 6 Preferred Shares shall be converted automatically into a number of duly authorized, validly issued, fully paid and nonassessable Class A Shares equal to the Conversion Amount following written notice by the Corporation to the holders of Series 6 Preferred Shares notifying such holders of the conversion contemplated by this SECTION 6(c), which conversion shall occur on the date specified in such notice, which shall not be less than ten (10) Business Days following the date of such notice (or in the case of the Investor and any Permitted Transferee the later of (A) the date of receipt of all antitrust approvals required in connection with such conversion (or the lapse of any applicable waiting period relating to such required antitrust approvals)) and (B) ten (10) Business Days following the date of such notice), provided, that (i) prior to March 14, 2024, such notice may be delivered by the Corporation (and such Series 6 Preferred Shares may be converted into Class A Shares pursuant to this SECTION 6(c)) only if the Closing Price per Class A Share for the thirty (30) consecutive Trading Day period ending on the Trading Day immediately prior to delivery of a notice of conversion pursuant to this SECTION 6(c) was at or above 125% of the then-applicable Conversion Price and (ii) following March 14, 2024, such notice may be delivered by the Corporation (and such Series 6 Preferred Shares may be converted into Class A Shares pursuant to this SECTION 6(c)) only if the Closing Price per Class A Share for the thirty (30) consecutive Trading Day period ending on the Trading Day immediately prior to delivery of a notice of conversion pursuant to this SECTION 6(c) was at or above 100% of the then-applicable Conversion Price; provided further, that following a Specified Event, the Corporation shall not be entitled to convert the Series 6 Preferred Shares.

Notwithstanding the foregoing, the holders of Series 6 Preferred Shares shall continue to have the right to convert their Series 6 Preferred Shares pursuant to SECTION 6(a) until and through the Conversion Date contemplated in this SECTION 6(c) and if such Series 6 Preferred Shares are converted pursuant to SECTION 6(a) such shares shall no longer be converted pursuant to this SECTION 6(c) and the Corporation’s notice delivered to the holders pursuant to this SECTION 6(c) shall be of no effect with respect to such shares converted pursuant to SECTION 6(a).

(d) Fractional Shares. No fractional Class A Shares will be issued upon conversion of the Series 6 Preferred Shares. In lieu of fractional shares, the Corporation shall round, to the nearest whole number, the number of Class A Shares to be issued upon conversion of the Series 6 Preferred Shares. If more than one Series 6 Preferred Share is being converted at one time by or for the benefit of the same holder, then the number of full shares issuable upon conversion will be calculated on the basis of the aggregate number of Series 6 Preferred Shares converted by or for the benefit of such holder at such time.

C-8

(e) Mechanics of Conversion.

(i) Promptly after the Conversion Date (and in any event within three (3) Business Days), the Corporation shall (A) issue and deliver to such holder the number of Class A Shares to which such holder is entitled in exchange for the certificates formerly representing Series 6 Preferred Shares and (B) pay to such holder, to the extent of funds legally available therefor, all declared and unpaid Dividends on the Series 6 Preferred Shares that are being converted into Class A Shares; provided, that any accrued and unpaid Dividends not paid to such holder pursuant to the foregoing clause (B) shall, subject to SECTION 6(b), be converted into a number of duly authorized, validly issued, fully paid and nonassessable Class A Shares equal to the number determined by dividing (x) the aggregate amount of such accrued and unpaid Dividends on the Series 6 Preferred Shares that are being converted by (y) the then current Conversion Price. Such conversion will be deemed to have been made on the Conversion Date, and the person entitled to receive the Class A Shares issuable upon such conversion shall be treated for all purposes as the record holder of such Class A Shares on such Conversion Date. In case fewer than all the shares represented by any such certificate are to be converted, a new certificate shall be issued representing the unconverted shares without cost to the holder thereof, except for any documentary, stamp or similar issue or transfer tax due because any certificates for Class A Shares or Series 6 Preferred Shares are issued in a name other than the name of the converting holder. The Corporation shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Class A Shares upon conversion or due upon the issuance of a new certificate for any Series 6 Preferred Shares not converted other than any such tax due because Class A Shares or a certificate for Series 6 Preferred Shares are issued in a name other than the name of the converting holder.

(ii) From and after the Conversion Date, the Series 6 Preferred Shares to be converted on such Conversion Date will no longer be deemed to be outstanding, and all rights of the holder thereof as a holder of Series 6 Preferred Shares (except the right to receive from the Corporation the Class A Shares upon conversion, together with the right to receive any accrued and unpaid Dividends thereon) shall cease and terminate with respect to such shares; provided, that in the event that a Series 6 Preferred Share is not converted, such Series 6 Preferred Share will remain outstanding and will be entitled to all of the rights as provided herein.

(iii) If the conversion is in connection with any sale, transfer or other disposition of the Class A Shares issuable upon conversion of the Series 6 Preferred Shares, the conversion may, at the option of any holder tendering any Series 6 Preferred Share for conversion, be conditioned upon the closing of the sale, transfer or the disposition of Class A Shares issuable upon conversion of Series 6 Preferred Shares with the underwriter, transferee or other acquirer in such sale, transfer or disposition, in which event such conversion of such Series 6 Preferred Shares shall not be deemed to have occurred until immediately prior to the closing of such sale, transfer or other disposition.

(iv) All Class A Shares issued upon conversion of the Series 6 Preferred Shares will, upon issuance by the Corporation, be duly and validly issued, fully paid and nonassessable.

(f) Adjustments to Conversion Price.

(i) Adjustment for Change In Share Capital.

(A) If the Corporation shall, at any time and from time to time while any Series 6 Preferred Shares are outstanding, issue a dividend or make a distribution on its Class A Shares payable in its Class A Shares to all or substantially all holders of its Class A Shares, then the Conversion Price at the opening of business on the Ex-Dividend Date for such dividend or distribution will be adjusted by multiplying such Conversion Price by a fraction:

(1) the numerator of which shall be the number of Class A Shares outstanding at the close of business on the Business Day immediately preceding such Ex-Dividend Date; and

C-9

(2) the denominator of which shall be the sum of the number of Class A Shares outstanding at the close of business on the Business Day immediately preceding the Ex-Dividend Date for such dividend or distribution, plus the total number of Class A Shares constituting such dividend or other distribution.

If any dividend or distribution of the type described in this SECTION 6(f)(i)(A) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. Except as set forth in the preceding sentence, in no event shall the Conversion Price be increased pursuant to this SECTION 6(f)(i)(A).

(B) If the Corporation shall, at any time or from time to time while any of the Series 6 Preferred Shares are outstanding, subdivide or reclassify its outstanding Class A Shares into a greater number of Class A Shares, then the Conversion Price in effect at the opening of business on the day upon which such subdivision becomes effective shall be proportionately decreased, and conversely, if the Corporation shall, at any time or from time to time while any of the Series 6 Preferred Shares are outstanding, combine or reclassify its outstanding Class A Shares into a smaller number of Class A Shares, then the Conversion Price in effect at the opening of business on the day upon which such combination or reclassification becomes effective shall be proportionately increased. In each such case, the Conversion Price shall be adjusted by multiplying such Conversion Price by a fraction, the numerator of which shall be the number of Class A Shares outstanding immediately prior to such subdivision or combination and the denominator of which shall be the number of Class A Shares outstanding immediately after giving effect to such subdivision, combination or reclassification. Such increase or reduction, as the case may be, shall become effective immediately after the opening of business on the day upon which such subdivision, combination or reclassification becomes effective.

(ii) Adjustment for Rights Issue. If the Corporation shall, at any time or from time to time, while any Series 6 Preferred Shares are outstanding, distribute rights, options or warrants to all or substantially all holders of its Class A Shares entitling them, for a period expiring within sixty (60) days after the record date for such distribution, to purchase Class A Shares, or securities convertible into, or exchangeable or exercisable for, Class A Shares, in either case, at less than the average of the Closing Prices for the five (5) consecutive Trading Days immediately preceding the first public announcement of the distribution, then the Conversion Price shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Price in effect at the opening of business on the Ex-Dividend Date for such distribution by a fraction:

(A) the numerator of which shall be the sum of (1) the number of Class A Shares Outstanding on the close of business on the Business Day immediately preceding the Ex-Dividend Date for such distribution, plus (2) the number of Class A Shares that the aggregate offering price of the total number of Class A Shares issuable pursuant to such rights, options or warrants would purchase at the Current Market Price of the Class A Shares on the declaration date for such distribution (determined by multiplying such total number of Class A Shares so offered by the exercise price of such rights, options or warrants and dividing the product so obtained by such Current Market Price); and

C-10

(B) the denominator of which shall be the number of Class A Shares Outstanding at the close of business on the Business Day immediately preceding the Ex-Dividend Date for such distribution, plus the total number of additional Class A Shares issuable pursuant to such rights, options or warrants.

The term “Class A Shares Outstanding” shall mean, without duplication, and include the following, and the following shall be included whether vested or unvested, whether contingent or non-contingent and whether exercisable or not yet exercisable, and without regard to any other limitations or restrictions on conversion or exercise:

(1) the number of Class A Shares, Class B Shares and Class C Shares then outstanding;

(2) all Class A Shares issuable upon conversion of outstanding Series 6 Preferred Shares; and

(3) all Class A Shares issuable upon exercise of outstanding options and any other Convertible Security.

Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend Date for such distribution.

To the extent that Class A Shares are not delivered pursuant to such rights, options or warrants or upon the expiration or termination of such rights, options or warrants, the Conversion Price shall be readjusted to the Conversion Price that would then be in effect had the adjustments made upon the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of Class A Shares actually delivered. In the event that such rights, options or warrants are not so distributed, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if the Ex-Dividend Date for such distribution had not occurred. In determining whether any rights, options or warrants entitle the holders to purchase Class A Shares at less than the average of the Closing Prices for the five (5) consecutive Trading Days immediately preceding the first public announcement of the relevant distribution, and in determining the aggregate offering price of such Class A Shares, there shall be taken into account any consideration received for such rights, options or warrants and the value of such consideration if other than cash, to be determined in good faith by the Board of Directors. Except as set forth in this paragraph, in no event shall the Conversion Price be increased pursuant to this SECTION 6(f)(ii).

C-11

(iii) Adjustment for Certain Tender Offers or Exchange Offers. In case the Corporation or any of its Subsidiaries shall, at any time or from time to time, while any Series 6 Preferred Shares are outstanding, distribute cash or other consideration in respect of a tender offer or an exchange offer (that is treated as a “tender offer” under U.S. federal securities laws) made by the Corporation or any Subsidiary for all or any portion of the Class A Shares, where the sum of the aggregate amount of such cash distributed and the aggregate Fair Market Value, as of the Expiration Date (as defined below), of such other consideration distributed (such sum, the “Aggregate Amount”) expressed as an amount per Class A Share validly tendered or exchanged, and not withdrawn, pursuant to such tender offer or exchange offer as of the Expiration Time (as defined below) (such tendered or exchanged Class A Shares, the “Purchased Shares”) exceeds the Closing Price per share of the Class A Shares on the Trading Day immediately following the last date (such last date, the “Expiration Date”) on which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (as the same may be amended through the Expiration Date), then, and in each case, immediately after the close of business on such date, the Conversion Price shall be decreased so that the same shall equal the rate determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Trading Day immediately following the Expiration Date by a fraction:

(A) the numerator of which shall be equal to the product of (1) the number of Class A Shares outstanding as of the last time (the “Expiration Time”) at which tenders or exchanges could have been made pursuant to such tender offer or exchange offer (including all Purchased Shares) and (2) the Closing Price per share of the Class A Shares on the Trading Day immediately following the Expiration Date; and

(B) the denominator of which is equal to the sum of (x) the Aggregate Amount and (y) the product of (I) an amount equal to (1) the number of Class A Shares outstanding as of the Expiration Time, less (2) the Purchased Shares and (II) the Closing Price per share of the Class A Shares on the Trading Day immediately following the Expiration Date.

An adjustment, if any, to the Conversion Price pursuant to this SECTION 6(f)(iii) shall become effective immediately prior to the opening of business on the second Trading Day immediately following the Expiration Date. In the event that the Corporation or a Subsidiary is obligated to purchase Class A Shares pursuant to any such tender offer or exchange offer, but the Corporation or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such tender offer or exchange offer had not been made. Except as set forth in the preceding sentence, if the application of this SECTION 6(f)(iii) to any tender offer or exchange offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer or exchange offer under this SECTION 6(f)(iii).

(iv) Disposition Events.

(A) If any of the following events (any such event, a “Disposition Event”) occurs:

(1) any reclassification or exchange of the Class A Shares (other than as a result of a subdivision or combination);

(2) any merger, amalgamation, consolidation or other combination to which the Corporation is a constituent party; or

(3) any sale, conveyance, lease, or other disposal of all or substantially all the properties and assets of the Corporation to any other person;

C-12

in each case, as a result of which all of the holders of Class A Shares shall be entitled to receive cash, securities or other property for their Class A Shares, the Series 6 Preferred Shares converted following the effective date of any Disposition Event shall be converted, in lieu of the Class A Shares otherwise deliverable, into the same amount and type (in the same proportion) of cash, securities or other property received by holders of Class A Shares in the relevant event (collectively, “Reference Property”) received upon the occurrence of such Disposition Event by a holder of Class A Shares holding, immediately prior to the transaction, a number of Class A Shares equal to the Conversion Amount (without giving effect to any limitations on conversion set forth in SECTION 6(b)) immediately prior to such Disposition Event; provided that if the Disposition Event provides the holders of Class A Shares with the right to receive more than a single type of consideration determined based in part upon any form of stockholder election, the Reference Property shall be comprised of the weighted average of the types and amounts of consideration received by the holders of the Class A Shares.

(B) The above provisions of this SECTION 6(f)(iv) shall similarly apply to successive Disposition Events. If this SECTION 6(f)(iv) applies to any event or occurrence, neither SECTION 6(f)(i) nor SECTION 6(f)(iii) shall apply; provided, however, that this SECTION 6(f)(iv) shall not apply to any share split or combination to which SECTION 6(f)(i) is applicable or to a liquidation, dissolution or winding up to which SECTION 3 applies. To the extent that equity securities of a company are received by the holders of Class A Shares in connection with a Disposition Event, the portion of the Series 6 Preferred Shares which will be convertible into such equity securities will continue to be subject to the anti-dilution adjustments set forth in this SECTION 6(f).

(v) Adjustment for Certain Issuances of Additional Class A Shares.

(A) Other than in respect of an issuance or distribution in respect of which SECTION 6(f)(ii) applies, in the event the Corporation shall at any time after the Series 6 Original Issuance Date while the Series 6 Preferred Shares are outstanding issue Additional Class A Shares, without consideration or for a consideration per share less than the applicable Conversion Price immediately prior to such issuance in effect on the date of and immediately prior to such issue, then and in such event, such Conversion Price shall be reduced, concurrently with such issuance, to a price determined by multiplying such Conversion Price by a fraction:

(1) the numerator of which shall be (a) the number of Class A Shares Outstanding (as defined below) immediately prior to such issuance plus (b) the number of Class A Shares which the aggregate consideration received or to be received by the Corporation for the total number of Class A Shares so issued would purchase at such Conversion Price; and

C-13

(2) the denominator of which shall be (a) the number of Class A Shares Outstanding immediately prior to such issue plus (b) the number of such Additional Class A Shares so issued.

(B) For purposes of this SECTION 6(f)(v), the term “Additional Class A Shares” means any Class A Shares or Convertible Security (collectively, “Class A Equivalents”) issued by the Corporation after the Series 6 Original Issuance Date, provided that Additional Class A Shares will not include any of the following:

(1) Class A Equivalents issued in a transaction for which an adjustment to the Conversion Price is made pursuant to SECTION 6(f)(i), SECTION 6(f)(iii) or SECTION 6(f)(iv);

(2) Class A Equivalents issued or issuable upon conversion of Series 6 Preferred Shares or Alternative Preference Shares or pursuant to the terms of any other Convertible Security issued and outstanding on the Series 6 Original Issuance Date;

(3) All Class A Shares, as adjusted for share dividends, splits, combinations and similar events, validly reserved on the Series 6 Original Issuance Date and issued or issuable upon the exercise of options or rights issued to employees, officers or directors of, or consultants, advisors or service providers to, the Corporation or any of its majority- or wholly-owned subsidiaries pursuant to any current equity incentive plans, programs or arrangements of or adopted by the Corporation, including the Corporation’s 2005 Stock Incentive Plan, the Corporation’s 2011 Stock Incentive Plan, the Corporation’s 2016 Stock Incentive Plan and the Corporation’s Amended and Restated Stock Appreciation Rights Plan;

(4) An unlimited number of Class A Equivalents issued pursuant to future equity incentive grants, plans, programs or arrangements adopted by the Corporation to the extent that any Class A Equivalents issued pursuant to this clause (4) shall not exceed three percent (3%) of the Corporation’s diluted weighted average number of common shares outstanding (as calculated for the Corporation’s financial reporting purposes) in any fiscal year, with any unused amounts in any fiscal year being carried over to succeeding fiscal years;

C-14

In the case of the issuance of Additional Class A Shares for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof. In the case of the issuance of Additional Class A Shares for consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the Fair Market Value thereof. In the case of the issuance of Convertible Securities, the aggregate maximum number of Class A Shares deliverable upon exercise, conversion or exchange of such Convertible Securities shall be deemed to have been issued at the time such Convertible Securities were issued and for a consideration equal to the consideration (determined in the manner provided in this paragraph) if any, received by the Corporation upon the issuance of such Convertible Securities plus the minimum additional consideration payable pursuant to the terms of such Convertible Securities for the Class A Shares covered thereby, but no further adjustment shall be made for the actual issuance of Class A Shares upon the exercise, conversion or exchange of any such Convertible Securities. In the event of any change in the number of Class A Shares deliverable upon exercise, conversion or exchange of Convertible Securities subject to this SECTION 6(f)(v), including, but not limited to, a change resulting from the anti-dilution provisions thereof, the Conversion Price shall forthwith be readjusted to such Conversion Price as would have been obtained had the adjustment that was made upon the issuance of such Convertible Securities not exercised, converted or exchanged prior to such change been made upon the basis of such change. Upon the expiration or forfeiture of any Additional Class A Shares consisting of options, warrants or other rights to acquire Class A Shares or Convertible Securities, the termination of any such rights to convert or exchange or the expiration or forfeiture of any options or rights related to such convertible or exchangeable securities, the Conversion Price, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities, shall be recomputed to reflect the issuance of only the number of Class A Shares (and Convertible Securities that remain in effect) actually issued upon the exercise of such options, warrants or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities.

(vi) Minimum Adjustment. Notwithstanding the foregoing, the Conversion Price will not be reduced if the amount of such reduction would be an amount less than $0.01, but any such amount will be carried forward and reduction with respect thereto will be made at the time that such amount, together with any subsequent amounts so carried forward, aggregates to $0.01 or more.

(vii) When No Adjustment Required. Notwithstanding anything herein to the contrary, no adjustment to the Conversion Price need be made:

(A) for a transaction referred to in SECTION 6(f)(i) or SECTION 6(f)(ii) if the Series 6 Preferred Shares participate, without conversion, in the transaction or event that would otherwise give rise to an adjustment pursuant to such Section at the same time as holders of the Class A Shares participate with respect to such transaction or event and on the same terms as holders of the Class A Shares participate with respect to such transaction or event as if the holders of Series 6 Preferred Shares, at such time, held a number of Class A Shares equal to the Conversion Amount at such time;

C-15

(B) for rights to purchase Class A Shares pursuant to any present or future plan by the Corporation for reinvestment of dividends or interest payable on the Corporation’s securities and the investment of additional optional amounts in Class A Shares under any plan; or

(viii) Rules of Calculation; Treasury Shares. All calculations will be made to the nearest one-hundredth of a cent or to the nearest one-ten thousandth of a share. Except as explicitly provided herein, the number of Class A Shares outstanding will be calculated on the basis of the number of issued and outstanding Class A Shares.

(ix) Waiver. Notwithstanding the foregoing, the Conversion Price will not be reduced if the Corporation receives, prior to the effective time of the adjustment to the Conversion Price, written notice from the holders representing at least a majority of the then outstanding Series 6 Preferred Shares, voting together as a separate class, that no adjustment is to be made as the result of a particular issuance of Class A Shares or other dividend or other distribution on Class A Shares. This waiver will be limited in scope and will not be valid for any issuance of Class A Shares or other dividend or other distribution on Class A Shares not specifically provided for in such notice.

(x) Tax Adjustment. Anything in this SECTION 6 notwithstanding, the Corporation shall be entitled to make such downward adjustments in the Conversion Price, in addition to those required by this SECTION 6, as the Board of Directors in its sole discretion shall determine to be advisable in order that any event treated for U.S. federal income tax purposes as a dividend or share split will not be taxable to the holders of Class A Shares.

(xi) No Duplication. If any action would require adjustment of the Conversion Price pursuant to more than one of the provisions described in this SECTION 6 in a manner such that such adjustments are duplicative, only one adjustment shall be made.

C-16

(xii) Provisions Governing Adjustment to Conversion Price. Rights, options or warrants distributed by the Corporation to all or substantially all holders of Class A Shares entitling the holders thereof to subscribe for or purchase shares of the Corporation’s capital (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Rights Trigger”): (A) are deemed to be transferred with such Class A Shares; (B) are not exercisable; and (C) are also issued in respect of future issuances of Class A Shares, shall be deemed not to have been distributed for purposes of SECTION 6(f)(i), (ii), (iii), (iv) or (v) (and no adjustment to the Conversion Price under SECTION 6(f)(i), (ii), (iii), (iv) or (v) will be required) until the occurrence of the earliest Rights Trigger, whereupon such rights, options and warrants shall be deemed to have been distributed, and (x) if and to the extent such rights, options and warrants are exercisable for Class A Shares or the equivalents thereof, an appropriate adjustment (if any is required) to the Conversion Price shall be made under SECTION 6(f)(ii) (without giving effect to the sixty (60) day limit on the exercisability of rights, options and warrants ordinarily subject to such SECTION 6(f)(ii)), and/or (y) if and to the extent such rights, options and warrants are exercisable for cash and/or any shares of the Corporation’s capital other than Class A Shares or Class A Share equivalents, shall be subject to the provisions of SECTION 2(a) applicable to Participating Dividends and shall be distributed to the holders of Series 6 Preferred Shares. If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the Series 6 Original Issuance Date, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Rights Trigger or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under SECTION 6(f)(i), (ii), (iii), (iv) or (v) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted at the opening of business of the Corporation immediately following such final redemption or repurchase by multiplying such Conversion Price by a fraction (x) the numerator of which shall be the Current Market Price per Class A Share on such date, less the amount equal to the per share redemption or repurchase price received by a holder or holders of Class A Shares with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all or substantially all holders of Class A Shares as of the date of such redemption or repurchase and (y) the denominator of which shall be the Current Market Price, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Price shall be readjusted as if such rights, options and warrants had not been issued. Notwithstanding the foregoing, (A) to the extent any such rights, options or warrants are redeemed by the Corporation prior to a Rights Trigger or are exchanged by the Corporation, in either case for Class A Shares, the Conversion Price shall be appropriately readjusted (if and to the extent previously adjusted pursuant to this SECTION 6(f)(xii)) as if such rights, options or warrants had not been issued, and instead the Conversion Price will be adjusted as if the Corporation had issued the Class A Shares issued upon such redemption or exchange as a dividend or distribution of Class A Shares subject to SECTION 6(f)(i)(A) and (B) to the extent any such rights, options or warrants are redeemed by the Corporation prior to a Rights Trigger or are exchanged by the Corporation, in either case for any shares of the Corporation’s capital (other than Class A Shares) or any other assets of the Corporation, such redemption or exchange shall be deemed to be a distribution and shall be subject to, and paid to the holders of Series 6 Preferred Shares pursuant to, the provisions of SECTION 2(a) applicable to Participating Dividends.

C-17

(xiii) Notwithstanding anything herein to the contrary, any adjustment of the Conversion Price or entitlement to acquire Class A Shares pursuant to this Designation shall be subject to the rules of the Exchange to the extent required to comply with such rules. If after the Series 6 Original Issuance Date there is a change in the applicable rules of the Exchange on which the Class A Shares are listed at the time such change becomes effective or in the interpretation of such applicable rules that would cause the Class A Shares to be delisted by such Exchange as a result of the terms of this Designation, the rights of the holders of the Series 6 Preferred Shares set forth in this Designation shall thereafter be limited to the extent required by such changed rules in order for the Class A Shares to continue to be listed on such Exchange. Notwithstanding anything to the contrary in this Designation, in no event shall the Conversion Price be adjusted pursuant to SECTION 6(f)(v) to a price that is less than the lower of: (i) the closing price of the Class A Shares (as reflected on ▇▇▇▇▇▇.▇▇▇) immediately preceding the signing of the Securities Purchase Agreement; or (ii) the average closing price of the Class A Shares (as reflected on ▇▇▇▇▇▇.▇▇▇) for the five trading days immediately preceding the signing of the Securities Purchase Agreement.

(xiv) Notwithstanding anything to the contrary in this Designation, if an adjustment to the Conversion Price becomes effective on any Ex-Dividend Date as described herein, and a holder of Series 6 Preferred Shares that have been converted on or after such Ex-Dividend Date and on or prior to the related record date would be treated as the record holder of Class A Shares as of the related Conversion Date based on an adjusted Conversion Price for such Ex-Dividend Date, then, notwithstanding such Conversion Price adjustment provisions, the Conversion Price adjustment relating to such Ex-Dividend Date will not be made for such converted Series 6 Preferred Shares. Instead, the holder of such converted Series 6 Preferred Shares will be treated as if such holder were the record owner of the Class A Shares on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Notice of Record Date. In the event of:

(i) any share split or combination of the outstanding Class A Shares;

(ii) any declaration or making of a dividend or other distribution to holders of Class A Shares in additional Class A Shares, any other share capital, other securities or other property (including, but not limited to, cash and evidences of indebtedness);

(iii) any reclassification or change to which SECTION 6(f)(i)(B) applies;

(iv) the dissolution, liquidation or winding up of the Corporation; or

(v) any other event constituting a Disposition Event;

then the Corporation shall file with its corporate records and mail to the holders of the Series 6 Preferred Shares at their last addresses as shown on the records of the Corporation, at least ten (10) days prior to the record date specified in (A) below or ten (10) days prior to the date specified in (B) below, a notice stating:

(A) the record date of such share split, combination, dividend or other distribution, or, if a record is not to be taken, the date as of which the holders of Class A Shares of record to be entitled to such share split, combination, dividend or other distribution are to be determined, or

C-18

(B) the date on which such reclassification, change, dissolution, liquidation, winding up or other event constituting a Disposition Event, is estimated to become effective, and the date as of which it is expected that holders of Class A Shares of record will be entitled to exchange their Class A Shares for the share capital, other securities or other property (including, but not limited to, cash and evidences of indebtedness) deliverable upon such reclassification, change, liquidation, dissolution, winding up or other Disposition Event.

Disclosures made by the Corporation in any public filings made under the Exchange Act shall be deemed to satisfy the notice requirements set forth in this SECTION 6(g).

(h) Certificate of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this SECTION 6, the Corporation shall compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Series 6 Preferred Shares a certificate, signed by an officer of the Corporation, setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the reasonable written request of any holder of Series 6 Preferred Shares, furnish to such holder a similar certificate setting forth (i) the calculation of such adjustments and readjustments in reasonable detail, (ii) the Conversion Price then in effect, and (iii) the number of Class A Shares and the amount, if any, of share capital, other securities or other property (including, but not limited to, cash and evidences of indebtedness) which then would be received upon the conversion of Series 6 Preferred Shares.

SECTION 7. Redemption.

(a) Redemption at the Option of the Corporation.

(i) In connection with or following any Specified Event, the Corporation, at its option and (if applicable) subject to consummation of such Specified Event, may redeem (out of funds legally available therefor) for cash all of the Series 6 Preferred Shares then outstanding at a price (the “Redemption Price”) per Series 6 Preferred Share equal to the greater of (i) the Base Liquidation Preference per such Series 6 Preferred Share plus all accrued and unpaid dividends thereon and (ii) an amount equal to the amount the holder of such Series 6 Preferred Shares would have received in respect of such Series 6 Preferred Share had such holder converted such Series 6 Preferred Share into Class A Shares immediately prior to such redemption based on the Current Market Price, in each case on the date of redemption (the “Redemption Date”).

(ii) If the Corporation elects to redeem the Series 6 Preferred Shares pursuant to this SECTION 7, on or prior to the fifteenth (15^th) Business Day prior to the applicable Redemption Date, the Corporation shall mail a written notice of redemption (the “Redemption Notice”) by first-class mail addressed to the holders of record of the Series 6 Preferred Shares as they appear in the records of the Corporation; provided, however, that accidental failure to give any such notice to one or more of such holders shall not affect the validity of such redemption. The Redemption Notice must state: (A) the expected Redemption Price as of the expected Redemption Date, and specify the individual components thereof (it being understood that the actual Redemption Price will be determined as of the actual Redemption Date); (B) the name of the redemption agent to whom, and the address of the place to where, the Series 6 Preferred Shares are to be surrendered for payment of the Redemption Price; (C) if applicable, that the consummation of the Redemption and the payment of the Redemption Price shall be subject to the consummation of the Specified Event, and (D) the anticipated Redemption Date.

C-19

(b) Mechanics of Redemption.

(ii) Series 6 Preferred Shares to be redeemed on the Redemption Date will from and after such date, no longer be deemed to be outstanding; and all powers, designations, preferences and other rights of the holder thereof as a holder of Series 6 Preferred Shares (except the right to receive from the Corporation the applicable Redemption Price) shall cease and terminate with respect to such shares; provided, that in the event that a Series 6 Preferred Share is not redeemed due to a default in payment by the Corporation or because the Corporation is otherwise unable to pay the applicable Redemption Price in cash in full, such Series 6 Preferred Share will remain outstanding and will be entitled to all of the powers, designations, preferences and other rights as provided herein.

(iii) Notwithstanding anything in this SECTION 7 to the contrary, each holder shall retain the right to convert Series 6 Preferred Shares to be redeemed at any time on or prior to the Redemption Date; provided, however, that any Series 6 Preferred Shares for which a holder delivers a conversion notice to the Corporation prior to the Redemption Date shall not be redeemed pursuant to this SECTION 7.

SECTION 8. Antitrust and Conversion Into Alternative Preference Shares.

(a) If (i) the Corporation validly delivers a notice of conversion pursuant to SECTION 6(c) to the Investor or any Permitted Transferee at any time on and after the date hereof and (ii) the Investor or such Permitted Transferee would not be permitted to convert one or more of its Beneficially Owned Series 6 Preferred Shares into Class A Shares because any applicable waiting period has not lapsed, or approval has not been obtained, under the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended, or other applicable law, the Accretion Rate will decrease to 0% per annum following, and the Base Liquidation Preference per Series 6 Preferred Share will not increase during any period subsequent to, ten (10) Business Days following the date of such validly delivered notice.

(b) With respect to any holder of Series 6 Preferred Shares other than the Investor or any Permitted Transferee, after receiving a notice of conversion pursuant to SECTION 6(c), any such holder of Series 6 Preferred Shares as to whom the relevant provisions of the following sentence are applicable may, at such holder’s option, convert Series 6 Preferred Shares subject to such conversion at any time on or prior to the close of business on the Business Day immediately preceding the Conversion Date, as the case may be, specified in such notice into Alternative Preference Shares to the extent necessary to address the conditions described in SECTION 8(c).

C-20

(c) (i) If any holder of Series 6 Preferred Shares would not be permitted to convert one or more of its Beneficially Owned Series 6 Preferred Shares into Class A Shares due to the restrictions contained in SECTION 6(b) or (ii) if any holder of Series 6 Preferred Shares other than the Investor or any Permitted Transferee would not be permitted to convert one more of its Beneficially Owned Series 6 Preferred Shares into Class A Shares (the shares described in clause (i) and (ii), the “Special Conversion Shares”) because any applicable waiting period has not lapsed, or approval has not been obtained, under the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended, or other applicable law, then in each case each Special Conversion Share of such holder shall be converted into a number of Alternative Preference Shares equal to the number of Class A Shares such holder would have received if such holder would have been permitted to convert such Special Conversion Shares into Class A Shares on the Conversion Date.

(d) As soon as practicable (and in any event within three (3) Business Days) after receipt of notice of either of the events described in SECTION 8(c), which notice shall include the amount of Alternative Preference Shares to which such holder is entitled and the basis for such conversion into Alternative Preference Shares, the Corporation shall (i) issue and deliver to such holder a certificate for the number of Alternative Preference Shares, if any, to which such holder is entitled in exchange for the certificates formerly representing the Series 6 Preferred Shares and (ii) pay to such holder, to the extent of funds legally available therefor, all declared and unpaid Dividends on the Series 6 Preferred Shares that are being converted into Alternative Preference Shares. Such conversion will be deemed to have been made on the Conversion Date, and the person entitled to receive the Alternative Preference Shares issuable upon such conversion shall be treated for all purposes as the record holder of such Alternative Preference Shares on such Conversion Date. In case fewer than all of the Series 6 Preferred Shares represented by any such certificate are to be converted into Alternative Preference Shares, a new certificate shall be issued representing the unconverted shares without cost to the holder thereof, except for any documentary, stamp or similar issue or transfer tax due because any certificates for Alternative Preference Shares or Series 6 Preferred Shares are issued in a name other than the name of the converting holder. The Corporation shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Alternative Preference Shares upon conversion or due upon the issuance of a new certificate for any Series 6 Preferred Shares not converted other than any such tax due because Alternative Preference Shares or a certificate for Series 6 Preferred Shares are issued in a name other than the name of the converting holder.
