(A) no dividend or distribution shall be declared or paid on the Common Stock or any other shares of Junior Stock, except dividends payable solely in shares of Common Stock;

(B) no dividend or distribution shall be declared or paid on Parity Stock, except as set forth in this Section 3(d); and

(C) no Common Stock, Junior Stock or Parity Stock shall be, directly or indirectly, purchased, redeemed or otherwise acquired for consideration by the Corporation or any of its Subsidiaries,

unless all accrued and unpaid dividends for all past Dividend Periods, including the latest completed Dividend Period, on all outstanding shares of Series A Preferred Stock have been or are contemporaneously declared and paid in full (or have been declared and a sum of cash or number of shares of Common Stock sufficient for the payment thereof has been set aside for the benefit of the Holders on the applicable Regular Record Date).

(ii) The limitations set forth in Section 3(d)(i) shall not apply to:

(A) redemptions, purchases or other acquisitions of shares of Common Stock or other Junior Stock in connection with the administration of any employee benefit plan in the

If the Board of Directors determines not to pay any dividend or a full dividend on a Dividend Payment Date, the Corporation will provide a 10 Business Days’ written notice to the Holders prior to such Dividend Payment Date.

Subject to the foregoing, dividends (payable in cash, securities or other property) as may be determined by the Board of Directors may be declared and paid on any securities of the Corporation, including Common Stock and other Junior Stock, from time to time out of any funds of the Corporation lawfully available for such payment, and Holders shall not be entitled to participate in any such dividends.

10

provided that in the case of a Fundamental Change Conversion that is a Reorganization Event, dividends otherwise payable in shares of Common Stock may be paid by delivery of Units of Exchange Property in accordance with Section 11(e); and provided further that if the Board of Directors may not lawfully authorize payment of all or any portion of such accrued and unpaid dividends in cash, it shall authorize payment of such dividends in shares of Common Stock or Units of Exchange Property, as the case may be, if lawfully permitted to do so.

(b) Each payment of a declared dividend on the Series A Preferred Stock shall be made in cash, except to the extent the Corporation timely elects to make all or any portion of such payment in shares of Common Stock. The Corporation shall give notice to Holders of any such election and the portions of such payment that will be made in cash and in shares of Common Stock no later than 10 Scheduled Trading Days prior to the Dividend Payment Date for such dividend; provided that if the Corporation does not provide timely notice of such election, the Corporation will be deemed to have elected to pay the relevant dividend in cash.

(c) If the Corporation elects to pay any dividend or portion thereof in shares of Common Stock, such shares of Common Stock shall be valued for such purpose at 97% of the Average VWAP per share of Common Stock over the five consecutive Trading Day period beginning on and including the seventh Scheduled Trading Day prior to the applicable Dividend Payment Date (the “ Average Price ”).

(d) Notwithstanding the foregoing, in no event shall the number of shares of Common Stock to be delivered, in connection with any declared dividend on the Series A Preferred Stock, including any dividend payable in connection with a conversion, exceed a number equal to the total dividend payment divided by $9.05, subject to adjustment in a manner inversely proportional to any adjustment to each Fixed Conversion Rate as set forth in Section 11 (such dollar amount, as adjusted from time to time, the “ Floor Price ”). To the extent that the amount of any declared dividend exceeds the product of (x) the number of shares of Common Stock delivered in connection with such declared dividend and (y) 97% of the Average Price, the Corporation shall, if it is legally able to do so, notwithstanding any notice by the Corporation to the contrary, pay such excess amount in cash.

(e) To the extent that the Corporation, in its reasonable judgment, determines that a Shelf Registration Statement is required in connection with the issuance of, or for resales of, shares of Common Stock issued as payment of a dividend on the Series A Preferred Stock, including dividends paid in connection with a conversion, the Corporation shall, to the extent such a Shelf Registration Statement is not currently filed and effective, use its commercially reasonable efforts to file and maintain the effectiveness of such a Shelf Registration Statement until the earlier of such time as all such shares of Common Stock have been resold thereunder and such time as all such shares would be freely tradable without registration by holders thereof that are not “affiliates” of the Corporation for purposes of the Securities Act of 1933, as amended. To the extent applicable, the Corporation shall also use its commercially reasonable efforts to have such shares of Common Stock qualified or registered under applicable state securities laws, if required, and approved for listing on the New York Stock Exchange (or if the shares of Common Stock are not then listed on the New York Stock Exchange, on the principal other U.S. national or regional securities exchange on which the shares of Common Stock are then listed).

(f) In respect of any cash paid, shares of Common Stock issued or Units of Exchange Property delivered in payment or partial payment of a dividend to a Non-U.S. Holder, the Corporation shall withhold and, in the case of such shares of Common Stock or Units of Exchange Property, the Corporation may do so by selling (or directing the Transfer Agent or any paying agent on behalf of the Corporation to withhold and sell) such amount in cash, number of shares of Common Stock or Units of Exchange Property as the Corporation deems necessary, to result in proceeds from such sale (after deduction of customary commissions, which shall be for the account of such Non-U.S. Holder) to pay all or any part of any U.S. withholding tax obligation that the Corporation has (as determined by it in its sole discretion) in respect of the payment or partial payment of such dividend of cash, shares of Common Stock or Units of Exchange Property to such Non-U.S. Holder.

SECTION 5. Mandatory Conversion on the Mandatory Conversion Date .

(a) Each outstanding share of Series A Preferred Stock shall automatically convert on the Mandatory Conversion Date into a number of shares of Common Stock equal to the Conversion Rate, unless such share of Series A Preferred Stock has been converted prior to the Mandatory Conversion Date in the manner described in Section 6 or Section 7; provided that if the Mandatory Conversion Date is not a Business Day, the Mandatory Conversion Date shall be postponed to the following Business Day; provided further , that if the Applicable Market Value is first determinable on a date later than the Mandatory Conversion Date because there are one or more Scheduled Trading Days that are not Trading Days during the 20 consecutive Scheduled Trading Day period commencing on and including the 22nd Scheduled Trading Day prior to the Mandatory Conversion Date, the Mandatory Conversion Date shall be postponed to such later date.

(b) Each of the Fixed Conversion Rates, the Initial Price, the Threshold Appreciation Price, the Floor Price, the Fundamental Change Date, and the Applicable Market Value shall be subject to adjustment in accordance with the provisions of Section 11.

(c) If prior to the Mandatory Conversion Date the Corporation has not declared all or any portion of the accumulated dividends on the Series A Preferred Stock, the Conversion Rate shall be adjusted so that Holders receive an additional number of shares of Common Stock equal to the amount of accumulated dividends that have not been declared (the “ Additional Conversion Amount ”) divided by the greater of the Floor Price and 97% of the Average Price. To the extent that the Additional Conversion Amount exceeds the product of such number of additional shares of Common Stock and the Applicable Market Value, the Corporation shall, if the Corporation is legally able to do so, declare and pay such excess amount in cash pro rata to the Holders.

SECTION 6. Optional Conversion at the Option of the Holder .

(a) Holders shall have the right to convert their shares of Series A Preferred Stock, in whole or in part (but in no event less than one share Series A Preferred Stock) (any conversion pursuant to this Section 6, an “ Optional Conversion ”), at any time prior to the Mandatory Conversion Date, other than during the Fundamental Change Conversion Period, into shares of Common Stock at the Minimum Conversion Rate, subject to adjustment in accordance with Section 11.

(b) If as of any Optional Conversion Date the Corporation has not declared all or any portion of the accumulated and unpaid dividends for all full Dividend Periods ending on a Dividend Payment Date prior to such Optional Conversion Date, the Minimum Conversion Rate shall be adjusted, with respect to the relevant Optional Conversion, so that the converting Holder receives an additional number of shares of Common Stock equal to the amount of accumulated and unpaid dividends that have not been declared for such Dividend Periods (the “ Optional Conversion Additional Conversion Amount ”), divided by the greater of the Floor Price and the Average VWAP per share of Common Stock over the 20 consecutive Scheduled Trading Day period commencing on, and including, the 22nd Trading Day prior to the Optional Conversion Date (such average being referred to as the “ Optional Conversion Average Price ”). To the extent that the Optional Conversion Additional Conversion Amount exceeds the product of the number of additional shares and the Optional Conversion Average Price, the Corporation will not have any obligation to pay the shortfall in cash. Except as described in the first sentence of this Section 6(b), upon any Optional Conversion of any shares of the Series A Preferred Stock, the Corporation shall make no payment or allowance for undeclared dividends on such shares of the Series A Preferred Stock, unless such Optional Conversion occurs after the Regular Record Date for a declared dividend and on or prior to the immediately succeeding Dividend Payment Date, in which case the Corporation shall pay such dividend on such Dividend Payment Date to the Record Holder of the converted shares as of such Regular Record Date, in accordance with Section 3.

(c) To effect an Optional Conversion, the converting Holder shall comply with the applicable conversion procedures set forth in Section 8. The Corporation shall, in accordance with the instructions provided by the Holder thereof in the written notice of conversion provided to the Corporation pursuant to Section 8, deliver to the Holder the whole number of shares of Common Stock to which the converting Holder shall be entitled upon such Optional Conversion, together with payment of cash in lieu of any fraction of a share of Common Stock, as

12

provided in Section 10, and any certificate or certificates, as the case may be, representing shares of Series A Preferred Stock, as provided in Section 8(d)(i). Such delivery shall take place on the third Business Day succeeding the Optional Conversion Date. If applicable, the Corporation shall instruct the Transfer Agent to register the whole number of shares of Common Stock to which the converting Holder shall be entitled upon such Optional Conversion in the name or names, as the case may be, specified by such Holder in the notice of conversion.

SECTION 7. Fundamental Change Conversion .

(a) If a Fundamental Change occurs on or prior to the Mandatory Conversion Date, Holders, subject to adjustments in accordance with Section 11, shall have the right to:

(i) convert their Series A Preferred Stock, in whole or in part (but in no event less than one Series A Preferred Stock) (any such conversion pursuant to this Section 7 being a “ Fundamental Change Conversion” ) at any time during the period (the “ Fundamental Change Conversion Period ”) from and including the Effective Date of such Fundamental Change to, but excluding, the earlier of (i) the Mandatory Conversion Date and (ii) the date that is 30 calendar days after the Effective Date (any conversion pursuant to this Section 7, a “ Fundamental Change Conversion ”) (1) into a number of shares of Common Stock equal to the Fundamental Change Conversion Rate per share of Series A Preferred Stock; or (2) if the Fundamental Change also constitutes a Reorganization Event, Units of Exchange Property in accordance with Section 11(e), based on the Fundamental Change Conversion Rate;

(ii) with respect to such converted shares, receive a Fundamental Change Dividend Make-whole Amount payable in cash or in shares of Common Stock; and

(iii) with respect to such converted shares, receive the Accumulated Dividend Amount payable in cash or in shares of Common Stock;

subject, in the case of clauses (ii) and (iii), to the Corporation’s right to deliver shares of Common Stock in lieu of all or part of such amounts as set forth in Section 7(d). Such delivery shall take place on the third Business Day following the applicable Fundamental Change Conversion Date.

Notwithstanding clauses (ii) and (iii), if such Effective Date or the relevant Fundamental Change Conversion Date falls during a Dividend Period for which the Corporation declared a dividend, the Corporation shall pay such dividend on such Dividend Payment Date to the Record Holders as of the immediately preceding Regular Record Date, in accordance with Section 3, and such dividend shall not be included in the Accumulated Dividend Amount, and the Fundamental Change Dividend Make-whole Amount shall not include the present value of such dividend.

(b) To the extent practicable, at least 20 calendar days prior to the anticipated Effective Date of the Fundamental Change, but in any event not later than two Business Days following the Corporation’s becoming aware of the occurrence of a Fundamental Change, a written notice shall be sent by or on behalf of the Corporation, by first-class mail, postage prepaid, to the Record Holders. Such notice shall contain:

(i) the date on which the Fundamental Change is anticipated to be effected;

(ii) the Fundamental Change Conversion Period;

(iii) the instructions a Holder must follow to effect a Fundamental Change Conversion in connection with such Fundamental Change; and

(iv) whether the Corporation has elected to pay all or any portion of accrued and unpaid dividends in shares of Common Stock or Units of Exchange Property, as the case may be, and, if so, the portion thereof (as a percentage) that will be paid in shares of Common Stock or Units of Exchange Property.

(c) To effect a Fundamental Change Conversion, the converting Holder must submit its Series A Preferred Stock for conversion and comply with the applicable conversion procedures set forth in Section 8 at any time

13

during the Fundamental Change Conversion Period. Holders who do not submit Series A Preferred Stock for conversion during the Fundamental Change Conversion Period will not be entitled to convert their Series A Preferred Stock at the Fundamental Change Conversion Rate or to receive the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount. To the extent a Holder does not convert its shares of Series A Preferred Stock pursuant to this Section 7 and a Reorganization Event has occurred, in lieu of shares of Common Stock, the Corporation shall pay or deliver, as the case may be, to such Holder on the Mandatory Conversion Date, Units of Exchange Property as determined in accordance with Section 11(e).

(d)(i) For any shares of Series A Preferred Stock that are converted during the Fundamental Change Conversion Period, in addition to the shares of Common Stock issued upon conversion at the Fundamental Change Conversion Rate, the Corporation will at its option:

(A) pay the Holder in cash, to the extent the Corporation is legally permitted to do so, the present value, computed using a discount rate of 5.50% per year, of all dividend payments on the Holder’s Series A Preferred Stock for all the remaining Dividend Periods (excluding any accumulated and unpaid dividends for all Dividend Periods ending on or prior to the Dividend Payment Date preceding the Effective Date of the Fundamental Change as well as dividends accumulated to the Effective Date of the Fundamental Change) from such Effective Date to but excluding the Mandatory Conversion Date (the “ Fundamental Change Dividend Make-whole Amount ”);

(B) increase the number of shares of Common Stock to be issued on conversion by a number equal to (x) the Fundamental Change Dividend Make-whole Amount divided by (y) the greater of the Floor Price and 97% of the Stock Price, or

(C) pay the Fundamental Change Dividend Make-whole Amount in a combination of cash and shares of Common Stock in accordance with the provisions of clauses (A) and (B) above.

(ii) In addition, for any Series A Preferred Stock that are converted during the Fundamental Change Conversion Period, to the extent that, as of the Effective Date of the Fundamental Change, the Corporation has not declared any or all of the accumulated dividends on the Series A Preferred Stock as of such Effective Date (including accumulated and unpaid dividends for all dividend periods ending on or prior to the Dividend Payment Date preceding the Effective Date of the Fundamental Change as well as dividends accumulated to the Effective Date of the Fundamental Change, the “ Accumulated Dividend Amount ”), Holders who convert Series A Preferred Stock within the Fundamental Change Conversion Period will be entitled to receive such Accumulated Dividend Amount upon conversion. The Accumulated Dividend Amount will be payable at the Corporation’s election in either:

(A) cash, to the extent the Corporation is legally permitted to do so,

(B) an additional number of shares of Common Stock equal to (x) the Accumulated Dividend Amount divided by (y) the greater of the Floor Price and 97% of the Stock Price, or

(C) a combination of cash and shares of Common Stock in accordance with the provisions of clauses (A) and (B) above.

(iii) The Corporation shall pay the Fundamental Change Dividend Make-whole Amount and the Accumulated Dividend Amount in cash, except to the extent the Corporation elects on or prior to the second Business Day following the Effective Date of a Fundamental Change to make all or any portion of such payments in shares of Common Stock. If the Corporation elects to deliver shares of Common Stock in respect of all or any portion of the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount, to the extent that the Fundamental Change Dividend Make-whole Amount or the Accumulated Dividend Amount or any portion thereof paid in shares of Common Stock exceeds the product of the number of additional shares the Corporation delivers in respect thereof and 97% of the Stock Price, the Corporation shall, if it is legally able to do so, declare and pay such excess amount in cash.

14

(e) Not later than the second Business Day following the Effective Date, the Corporation shall notify Holders of:

(i) the Fundamental Change Conversion Rate;

(ii) the Fundamental Change Dividend Make-whole Amount and whether the Corporation will pay such amount in cash, shares of Common Stock or a combination thereof, and specifying the combination thereof, if applicable; and

(iii) the Accumulated Dividend Amount as of the Effective Date and whether the Corporation will pay such amount in cash, shares of Common Stock or a combination thereof, and, specifying the combination thereof, if applicable.

SECTION 8. Conversion Procedures .

(a) On the Mandatory Conversion Date, any Fundamental Change Conversion Date or any Optional Conversion Date (each, a “ Conversion Date ”), dividends on any shares of Series A Preferred Stock converted to Common Stock shall cease to accrue and accumulate, and on the Conversion Date, such converted shares of Series A Preferred Stock shall cease to be outstanding, in each case, subject to the right of Holders of such shares of Series A Preferred Stock to receive shares of Common Stock (or Units of Exchange Property, if applicable) into which such shares of Series A Preferred Stock were converted and any accrued and unpaid dividends on such shares to which such Holders are otherwise entitled pursuant to Section 5(c), Section 6(b) or Section 7(d), as applicable.

(b) Subject to postponement as described in Section 5(a), on the Mandatory Conversion Date, pursuant to Section 5, any outstanding shares of Series A Preferred Stock shall automatically convert into shares of Common Stock. The Person or Persons entitled to receive the Common Stock issuable upon any such conversion of the Series A Preferred Stock shall be treated as the Record Holder or Record Holders, as the case may be, of such shares of Common Stock as of 5:00 p.m., New York City time, on the applicable Conversion Date. Except as provided under Section 11, prior to 5:00 p.m., New York City time, on such applicable Conversion Date, shares of Common Stock issuable upon conversion of any shares of Series A Preferred Stock shall not be outstanding for any purpose, and Holders of shares of Series A Preferred Stock shall have no rights with respect to such shares of Common Stock, including, without limitation, voting rights, rights to respond to tender offers for the Common Stock and rights to receive any dividends or other distributions on the Common Stock, by virtue of holding shares of Series A Preferred Stock. No allowance or adjustment, except as set forth in Section 11, shall be made in respect of dividends payable to holders of record of Common Stock as of any date prior to such applicable Conversion Date.

(c) To effect an Optional Conversion pursuant to Section 6 or a Fundamental Change Conversion pursuant to Section 7, a Holder who

(i) holds a beneficial interest in a Global Preferred Share must deliver to DTC the appropriate instruction form for conversion pursuant to DTC’s conversion program and, if required, pay all transfer or similar taxes or duties, if any; or

(ii) holds Series A Preferred Stock in definitive, certificated form must:

(A) complete and manually sign the conversion notice on the back of the Series A Preferred Stock certificate or a facsimile of such conversion notice;

(B) deliver the completed conversion notice and the certificated Series A Preferred Stock to be converted to the Conversion and Dividend Disbursing Agent;

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

(D) if required, pay all transfer or similar taxes or duties, if any.

15

(the day on which the Holder complies with such requirements, the “ Optional Conversion Date ” or the “ Fundamental Change Conversion Date ”, as the case may be); provided that, the Fundamental Change Conversion Date shall be a date no earlier than the Effective Date of the Fundamental Change and no later than 5:00 p.m., New York City time, on the last day of the Fundamental Change Conversion Period.

The issuance by the Corporation of shares of Common Stock upon an Optional Conversion shall be deemed effective immediately prior to 5:00 p.m., New York City time, on the Optional Conversion Date.

(d) With respect to any Optional Conversion or any Fundamental Change Conversion of shares of Series A Preferred Stock:

(i) if there shall have been surrendered certificate or certificates, as the case may be, representing a greater number of shares of Series A Preferred Stock than the number of shares of Series A Preferred Stock to be converted, the Corporation shall execute and the Registrar shall countersign and deliver to such Holder or such Holder’s designee, at the expense of the Corporation, new certificate or certificates, as the case may be, representing the number of shares of Series A Preferred Stock that shall not have been converted; and

(ii) if the shares of Series A Preferred Stock converted are held in book-entry form through the facilities of the Depositary, promptly following the relevant Optional Conversion Date or Fundamental Change Conversion Date, as the case may be, the Corporation shall cause the Transfer Agent and Registrar to reduce the number of shares of Series A Preferred Stock represented by the global certificate by making a notation on Schedule I attached to the relevant Global Preferred Share.

SECTION 9. Reservation of Common Stock .

(a) The Corporation shall at all times reserve and keep available out of its authorized and unissued shares of Common Stock, solely for issuance, the full number of shares of Common Stock issuable upon payment of accrued and unpaid dividends and upon conversion of the Series A Preferred Stock at the Maximum Conversion Rate then in effect.

(b) All shares of Common Stock delivered upon conversion of the Series A Preferred Stock shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, charges, security interests and other encumbrances (other than liens, claims, charges, security interests and other encumbrances created by the Holders).

(c) Prior to the delivery of any securities that the Corporation shall be obligated to deliver upon conversion of the Series A Preferred Stock, the Corporation shall use its reasonable best efforts to comply with all federal and state laws and regulations thereunder, if any, requiring the registration of such securities with, or any approval of or consent to the delivery thereof by, any governmental authority.

(d) The Corporation hereby covenants and agrees that, if at any time the Common Stock shall be listed on the New York Stock Exchange or any other national securities exchange or automated quotation system, the Corporation shall, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Series A Preferred Stock and payment of dividends thereon, if any; provided , however , that if the rules of such exchange or automated quotation system permit the Corporation to defer the listing of such Common Stock until the first conversion of Series A Preferred Stock into Common Stock in accordance with the provisions hereof, the Corporation covenants to list such Common Stock issuable upon conversion of the Series A Preferred Stock in accordance with the requirements of such exchange or automated quotation system at such time.

16

SECTION 10. Fractional Shares .

(a) No fractional shares of Common Stock or any other common stock or ADRs included in the Exchange Property shall be issued to Holders, including as a result of any conversion of shares of Series A Preferred Stock or as a result of any payment of dividends on the Series A Preferred Stock in shares of Common Stock or Units of Exchange Property.

(b) In lieu of any fractional share of Common Stock or any other common stock or ADRs included in the Exchange Property otherwise issuable upon Mandatory Conversion, Optional Conversion or Fundamental Change Conversion (including in connection with a dividend payment in connection therewith), that Holder shall be entitled to receive an amount in cash (computed to the nearest cent) based on the VWAP per share of Common Stock, or, if applicable, such other common stock or ADR, on the Trading Day immediately preceding the applicable Conversion Date. In lieu of any fractional shares of Common Stock that would otherwise be delivered to a Holder in payment or partial payment of any dividend pursuant to Section 4(b), the Holder will be entitled to receive an amount in cash (computed to the nearest cent) based on the Average Price with respect to such dividend.

(c) If more than one share of the Series A Preferred Stock is surrendered for conversion at one time by or for the same Holder, the number of full shares of Common Stock, or, if applicable, other common stock or full ADRs, issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series A Preferred Stock so surrendered for conversion. If the Corporation pays dividends in Common Stock, other common stock or ADRs pursuant to Section 4(b) on more than one share of Series A Preferred Stock held at any one time by or for the same Holder, the number of full shares of Common Stock, or, if applicable, other common stock or full ADRs, payable in connection with such dividend shall be computed on the basis of the aggregate number of shares of Series A Preferred Stock so surrendered for conversion.

SECTION 11. Conversion Rate Adjustments to the Fixed Conversion Rates .

(a) Each Fixed Conversion Rate shall be adjusted from time to time as follows:

(i) If the Corporation issues Common Stock as a dividend or distribution to all or substantially all holders of the Common Stock, or if the Corporation effects a subdivision or combination (including, without limitation, a stock split or a reverse stock split) of the Common Stock, each Fixed Conversion Rate shall be adjusted based on the following formula:

17

Any adjustment made under this Section 11(a)(i) shall become effective immediately after 5:00 p.m., New York City time, on the Record Date for such dividend or distribution, or immediately after 9:00 a.m., New York City time, on the effective date for such subdivision or combination, as the case may be. If any dividend, distribution, subdivision or combination of the type described in this clause (i) is declared but not so paid or made, each Fixed Conversion Rate shall be immediately readjusted, effective as of the earlier of (a) the date the Board of Directors determines not to pay or make such dividend, distribution, subdivision or combination and (b) the date the dividend or distribution was to be paid or the date the subdivision or combination was to have been effective, to the Fixed Conversion Rate that would then be in effect if such dividend, distribution, subdivision or combination had not been declared.

(ii) If the Corporation issues to all or substantially all holders of the Common Stock any rights (other than pursuant to any stockholder rights plan), options or warrants entitling them for a period expiring 60 days or less from the date of issuance of such rights, options or warrants to subscribe for or purchase shares of Common Stock at less than the Average VWAP per share of Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, each Fixed Conversion Rate will be increased based on the following formula:

where,

18

Any increase in the Fixed Conversion Rates made pursuant to this Section 11(a)(ii) shall become effective immediately after 5:00 p.m., New York City time, on the Record Date for such issuance. To the extent such rights, options or warrants are not exercised prior to their expiration or termination, each Fixed Conversion Rate shall be decreased, effective as of the date of such expiration or termination, to the Fixed Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, each Fixed Conversion Rate shall be decreased, effective as of the earlier of (a) the date the Board of Directors determines not to issue such rights, options or warrants and (b) the date such rights, options or warrants were to have been issued, to the Fixed Conversion Rate that would then be in effect if such issuance had not been announced.

For purposes of this Section 11(a)(ii), in determining whether any rights, options or warrants entitle the holders thereof to subscribe for or purchase shares of the Common Stock at less than the Average VWAP per share of Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration the Corporation receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors.

(iii) If the Corporation pays a dividend or other distribution to all or substantially all holders of Common Stock of shares of the Corporation’s capital stock (other than Common Stock), evidences of the Corporation’s indebtedness, the Corporation’s assets or rights to acquire the capital stock, indebtedness or assets of the Corporation, excluding:

19

then each Fixed Conversion Rate shall be increased based on the following formula:

If the Board of Directors determines the “FMV” (as defined in this Section 11(a)(iii)) of any dividend or other distribution for purposes of this Section 11(a)(iii) by referring to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the Average VWAP per share of Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Record Date for such dividend or distribution.

Notwithstanding the foregoing, if “FMV” (as defined in this Section 11(a)(iii)) is equal to or greater than “SP ₀ ” (as defined in this Section 11(a)(iii)), in lieu of the foregoing increase, each Holder shall receive, in respect of each share of Series A Preferred Stock, at the same time and upon the same terms as holders of Common Stock, the amount and kind of shares of the Corporation’s capital stock (other than Common Stock), evidences of the Corporation’s indebtedness, the Corporation’s assets or rights to acquire the capital stock, indebtedness or assets of the Corporation that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Conversion Rate in effect immediately prior to 5:00 p.m., New York City time, on the Record Date for such dividend or other distribution.

Any increase made under the portion of this Section 11(a)(iii) above shall become effective immediately after 5:00 p.m., New York City time, on the Record Date for such dividend or other distribution. If such dividend or distribution is not so paid or made, each Fixed Conversion Rate shall be decreased, effective as of

20

the earlier of (a) the date the Board of Directors determines not to pay the dividend or other distribution and (b) the date such dividend or distribution was to have been paid, to the Fixed Conversion Rate that would then be in effect if the dividend or other distribution had not been declared.

If the transaction that gives rise to an adjustment pursuant to this Section 11(a)(iii) is one pursuant to which the payment of a dividend or other distribution on the Common Stock consists of shares of capital stock of, or similar equity interests in, a Subsidiary or other business unit of the Corporation (a “ Spin-Off ”) that are, or, when issued, will be, traded on a U.S. national securities exchange or a reasonably comparable non-U.S. equivalent, then each Fixed Conversion Rate shall instead be increased based on the following formula:

where,

The adjustment to each Fixed Conversion Rate under the immediately preceding paragraph shall occur at 5:00 p.m., New York City time, on the 10th consecutive Trading Day immediately following, and including, the Ex-Dividend Date for such dividend or distribution, but will be given effect as of 9:00 a.m., New York City time, on the date immediately following the Record Date for such dividend or distribution. The Corporation shall delay the settlement of any conversion of shares of the Series A Preferred Stock if the Conversion Date occurs after the Record Date for such dividend or distribution and prior to the end of such 10 consecutive Trading Day period. In such event, the Corporation shall deliver the shares of Common Stock issuable in respect of such conversion (based on the adjusted Fixed Conversion Rates as described above) on the first Business Day immediately following the last Trading Day of such 10 consecutive Trading Day period.

21

For purposes of this Section 11(a)(iii) (and subject in all respects to Section 11(a)(i) and Section 11(a)(ii)):

(A) rights, options or warrants distributed by the Corporation to all or substantially all holders of the Common Stock entitling them to subscribe for or purchase shares of the Corporation’s capital stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“ Trigger Event ”):

(i) are deemed to be transferred with such shares of the Common Stock;

(ii) are not exercisable; and

(iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 11(a)(iii) (and no adjustment to the Fixed Conversion Rates under this Section 11(a)(iii) shall be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Fixed Conversion Rates shall be made under this Section 11(a)(iii).

(B) If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the Issue 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 Record Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof).

(C) In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding clause (B)) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Fixed Conversion Rates under this clause (iii) 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, upon such final redemption or repurchase (x) the Fixed Conversion Rates shall be readjusted as if such rights, options or warrants had not been issued and (y) the Fixed Conversion Rates shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution pursuant to Section 11(a)(iv), equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase; 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 Fixed Conversion Rates shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 11(a)(i), Section 11(a)(ii) and this Section 11(a)(iii), if any dividend or distribution to which this Section 11(a)(iii) is applicable includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 11(a)(i) is applicable (the “ Clause A Distribution ”); or

(B) an issuance of rights, options or warrants to which Section 11(a)(ii) is applicable (the “ Clause B Distribution ”),

then:

(1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 11(a)(iii) is applicable (the “ Clause C Distribution ”) and any Fixed Conversion Rate adjustment required by this Section 11(a)(iii) with respect to such Clause C Distribution shall then be made; and

22

(2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Fixed Conversion Rate adjustment required by Section 11(a)(i) and Section 11(a)(ii) with respect thereto shall then be made, except that, if determined by the Corporation (I) the “Record Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Record Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to 5:00 p.m., New York City time, on such Record Date or immediately prior to 9:00 a.m., New York City time, on such effective date” within the meaning of Section 11(a)(i) or “outstanding immediately prior to 5:00 p.m., New York City time, on such Record Date” within the meaning of Section 11(a)(ii).

(iv) If the Corporation pays a distribution consisting exclusively of cash to all or substantially all holders of the Common Stock, each Fixed Conversion Rate shall be increased based on the following formula:

Notwithstanding the foregoing, if “C” (as defined in this Section 11(a)(iv)) is equal to or greater than “SP ₀ ” (as defined in this Section 11(a)(iv)), in lieu of the foregoing increase, each Holder shall receive, in respect of each share of Series A Preferred Stock, at the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Conversion Rate in effect immediately prior to 5:00 p.m., New York City time, on the Record Date for such distribution.

Any adjustment to the Fixed Conversion Rates pursuant to this Section 11(a)(iv) shall become effective immediately after 5:00 p.m., New York City time, on the Record Date for such distribution. If

23

such distribution is not so paid, the Fixed Conversion Rates shall be decreased, effective as of the earlier of (a) the date the Board of Directors determines not to pay such dividend and (b) the date such dividend was to have been paid, to the Fixed Conversion Rates that would then be in effect if such distribution had not been declared.

(v) If the Corporation or one or more of its Subsidiaries purchases Common Stock pursuant to a tender offer or exchange offer (except as provided in Section 11(c)(iii)) and the cash and value of any other consideration included in the payment per share of Common Stock validly tendered or exchanged exceeds the Average VWAP per share of Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “ Expiration Date ”), each Fixed Conversion Rate shall be increased based on the following formula:

where:

24

The adjustment to each Fixed Conversion Rate under this Section 11(a)(v) shall occur at 5:00 p.m., New York City time, on the tenth consecutive Trading Day immediately following, and including, the Trading Day immediately following the Expiration Date, but will be given effect as of 9:00 a.m., New York City time, on the Expiration Date. The Corporation shall delay the settlement of any conversion of Series A Preferred Stock if the Conversion Date occurs during such 10 consecutive Trading Day period. In such event, the Corporation shall deliver the shares of Common Stock issuable in respect of such conversion (based on the adjusted Fixed Conversion Rates) on the first Business Day immediately following the last Trading Day of such 10 consecutive Trading Day period.

(vi) If the Corporation has in effect a stockholder rights plan while any shares of Series A Preferred Stock remain outstanding, Holders shall receive, upon a conversion of Series A Preferred Stock, in addition to Common Stock, rights under the Corporation’s stockholder rights agreement unless, prior to such conversion, the rights have expired, terminated or been redeemed or unless the rights have separated from the Common Stock. If the rights provided for in the stockholder rights plan have separated from the Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that Holders would not be entitled to receive any rights in respect of the Common Stock, if any, that the Corporation is required to deliver upon conversion of Series A Preferred Stock, each Fixed Conversion Rate shall be adjusted at the time of separation as if the Corporation had distributed to all holders of the Common Stock, capital stock (other than Common Stock), evidences of the Corporation’s indebtedness, the Corporation’s assets or rights to acquire the capital stock, indebtedness or assets of the Corporation pursuant to Section 11(a)(iii) above, subject to readjustment upon the subsequent expiration, termination or redemption of the rights. A distribution of rights pursuant to a stockholder rights plan will not trigger an adjustment to the Fixed Conversion Rates pursuant to Section 11(a)(ii) or Section 11(a)(iii) above.

(b) Adjustment for Tax Reasons . The Corporation may make such increases in each Fixed Conversion Rate, in addition to any other increases required by this Section 11, if the Board of Directors deems it advisable in order to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of the Corporation’s shares (or issuance of rights or warrants to acquire shares) or from any event treated as such for income tax purposes or for any other reasons; provided that the same proportionate adjustment must be made to each Fixed Conversion Rate. If any adjustment to the Fixed Conversion Rate is treated as a distribution to any Non-U.S. Holder which is subject to withholding tax, the Corporation (or Transfer Agent or any paying agent on behalf of the Corporation) may set off any withholding tax that is required to be collected with respect to such deemed distribution against cash payments and other distributions otherwise deliverable to such Non-U.S. Holder.

(c) Calculation of Adjustments; Adjustments to Threshold Appreciation Price, Initial Price, Applicable Market Value and Five-Day Average VWAP .

(i) All required calculations will be made to the nearest cent or 1/10,000th of a share.

If an adjustment is made to the Fixed Conversion Rates pursuant to this Section 11, an inversely proportional adjustment shall also be made (x) to the Threshold Appreciation Price and the Initial Price solely for purposes of determining which of clauses (i), (ii) and (iii) of the definition of Conversion Rate shall apply on the Mandatory Conversion Date (subject to postponement as described in Section 5(a)), and (y) to the Floor Price. Such adjustment shall be made by dividing each of the Threshold Appreciation Price and the Initial Price by a fraction, the numerator of which shall be either Fixed Conversion Rate immediately after such adjustment pursuant to clause (i), (ii), (iii), (iv) or (v) of Section 11(a) or Section 11(b) and the denominator of which shall be such Fixed Conversion Rate immediately before such adjustment. The Corporation shall make appropriate adjustments to the VWAP per share of Common

25

Stock used to calculate the Applicable Market Value or the Five-Day Average VWAP, as the case may be, to account for any adjustments to the Fixed Conversion Rates that became effective during the period in which the Applicable Market Value or the Five-Day Average VWAP, as the case may be, is being calculated.

(ii) Notwithstanding Section 11(a), no adjustment to the Fixed Conversion Rates shall be made if Holders participate in the transaction that would otherwise require an adjustment (other than in the case of a share split or share combination), at the same time, upon the same terms and otherwise on the same basis as holders of the Common Stock and solely as a result of holding shares of Series A Preferred Stock, as if such Holders held a number of shares of Common Stock equal to the Maximum Conversion Rate as of the Record Date for such transaction, multiplied by the number of shares of Series A Preferred Stock held by such Holders.

(iii) The Fixed Conversion Rates shall not be adjusted except as provided herein. Without limiting the foregoing, the Fixed Conversion Rates shall not be adjusted for:

(A) the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Corporation’s securities and the investment of additional optional amounts in the Common Stock under any plan;

(B) the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, employee agreement or arrangement or program of the Corporation or any Subsidiaries of the Corporation;

(C) the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Issue Date;

(D) a change solely in the par value of the Common Stock;

(E) stock repurchases that are not tender offers, including structured or derivative transactions;

(F) as a result of a tender offer solely to holders of fewer than 100 shares of Common Stock;

(G) a third-party tender or exchange offer; or

(H) the payment of dividends on the Series A Preferred Stock, whether in cash or in shares of Common Stock.

(iv) The Corporation shall have the power to resolve any ambiguity and its action in so doing, as evidenced by a resolution of the Board of Directors, shall be final and conclusive unless clearly inconsistent with the intent hereof.

(d) Notice of Adjustment . Whenever a Fixed Conversion Rate or the Fundamental Change Conversion Rate, as applicable, is to be adjusted, the Corporation shall: (i) compute such adjusted Fixed Conversion Rate or the Fundamental Change Conversion Rate, as applicable, and prepare and transmit to the Transfer Agent an Officers’ Certificate setting forth such adjusted Fixed Conversion Rate or the Fundamental Change Conversion Rate, as applicable, the method of calculation thereof in reasonable detail and the facts requiring such adjustment and upon which such adjustment is based; (ii) as soon as practicable following the determination of a revised Fixed Conversion Rate or Fundamental Change Conversion Rate, as applicable, provide, or cause to be provided, a written notice to Holders of the occurrence of such event and (iii) as soon as practicable following the determination of a revised Fixed Conversion Rate or Fundamental Change Conversion Rate, as applicable, provide, or cause to be provided, to Holders a statement setting forth in reasonable detail the method by which the adjustment to such Fixed Conversion Rate or the Fundamental Change Conversion Rate, as applicable, was determined and setting forth such revised Fixed Conversion Rate or Fundamental Change Conversion Rate, as applicable.

26

(e) Recapitalizations, Reclassifications and Changes of the Common Stock. In the event of:

(A) any recapitalization, reclassification or change of the Common Stock (other than changes only in par value or resulting from a subdivision or combination);

(B) any consolidation or merger of the Corporation with or into another Person or any statutory exchange or binding share exchange; or

(C) any sale, transfer, lease or conveyance to another Person of all or substantially all of the property and assets of the Corporation and its Subsidiaries;

in each case as a result of which the shares of Common Stock are exchanged for, or converted into, other securities, property or assets (including cash or any combination thereof) (any such event, a “ Reorganization Event ”), then, at the effective time of such Reorganization Event, each share of Series A Preferred Stock outstanding immediately prior to such Reorganization Event shall, without the consent of Holders, become convertible into the kind and amount of such other securities, property or assets (including cash or any combination thereof) that holders of the Common Stock received in such Reorganization Event (the “ Exchange Property ”), and, at the effective time of such Reorganization Event, the Corporation shall amend the Certificate of Designations to provide for such change in the convertibility of the Series A Preferred Stock; provided that if the kind and amount of Exchange Property receivable upon such Reorganization Event is not the same for each share of Common Stock held immediately prior to such Reorganization Event by a Person, then the Exchange Property receivable upon such Reorganization Event shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of the Common Stock that affirmatively make an election with respect to the kind and amount of Exchange Property so receivable (or of all such holders if none makes an election). The Conversion Rate then in effect shall be applied on the applicable Conversion Date to the amount of such Exchange Property received per share of Common Stock in the Reorganization Event (a “ Unit of Exchange Property ”), as determined in accordance with this Section 11(e). For the purpose of determining which clause of the definition of Conversion Rate shall apply on the Mandatory Conversion Date (subject to postponement as described in Section 5(a)) and for the purpose of calculating the Conversion Rate if clause (ii) of the definition thereof is applicable, the value of a Unit of Exchange Property shall be determined in good faith by the Board of Directors, except that if a Unit of Exchange Property includes common stock or American Depositary Receipts (“ ADRs ”) that are traded on a U.S. national securities exchange, the value of such common stock or ADRs shall be the Applicable Market Value determined with regard to a share of such common stock or a single ADR, as the case may be (or for the purpose of determining the Stock Price on a Fundamental Change Conversion Date, the value of such common stock or ADRs shall be the Five-Day Average VWAP determined with regard to a share of such common stock or a single ADR, as the case may be). For the purpose of paying accrued and unpaid dividends in Units of Exchange Property in accordance with Section 4, the value of a Unit of Exchange Property shall equal 97% of the value determined pursuant to the immediately preceding sentence.

The above provisions of this Section 11(e) shall similarly apply to successive Reorganization Events and the provisions of Section 11(a)-(d) shall apply to any shares of capital stock of the Corporation (or of any successor) received by the holders of Common Stock in any such Reorganization Event.

The amendment to the Certificate of Designations providing that the Series A Preferred Stock shall be convertible into Exchange Property shall also provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments described under this Section 11. The Corporation shall not become a party to any Reorganization Event unless the terms of such transaction are consistent with this Section 11(e).

The Corporation (or any successor) shall, as soon as reasonably practicable (but in any event within five Business Days) after the occurrence of any Reorganization Event, provide written notice to the Holders of such occurrence of such Reorganization Event and of the kind and amount of the cash, securities or other property that constitute the Exchange Property. Failure to deliver such notice shall not affect the operation of this Section 11(e).

27

(f) For purposes of this Section 11, the number of shares of Common Stock at any time outstanding shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

SECTION 12. Liquidation Rights .

(a) Voluntary or Involuntary Liquidation . In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, each Holder shall be entitled to receive for each share of Series A Preferred Stock, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to stockholders of the Corporation, subject to the rights of any creditors of the Corporation, before any payment or distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other Junior Stock of the Corporation, payment in full in an amount equal to the sum of (x) the Initial Liquidation Preference and (y) an amount equal to any accrued and unpaid dividends on each share of Series A Preferred Stock, whether or not declared, to (but not including) the date fixed for liquidation, dissolution or winding up (such amounts collectively, the “ Liquidation Preference ”).

(b) Partial Payment . If in any distribution described in Section 12(a) the assets of the Corporation or proceeds thereof are not sufficient to pay in full the amounts payable with respect to all outstanding shares of Series A Preferred Stock and any Parity Stock as to such distribution, Holders and the holders of such Parity Stock shall share ratably in any such distribution in proportion to the full accrued and unpaid respective distributions to which they are entitled.

(c) Residual Distributions . After payment of the full amount of the Liquidation Preference, including an amount equal to any accrued and unpaid dividends, to which they are entitled, Holders will have no right or claim to any of the remaining assets of the Corporation (or proceeds thereof).

(d) Merger, Consolidation and Sale of Assets Not Liquidation . For purposes of this Section 12, the merger or consolidation of the Corporation with or into any other corporation or other entity, or the sale, lease or exchange (for cash, securities or other property) of all or substantially all of the assets of the Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation.

SECTION 13. No Sinking Fund . The Series A Preferred Stock will not be subject to any mandatory redemption, sinking fund or other similar provisions.

SECTION 14. Status of Converted or Repurchased Shares . Shares of Series A Preferred Stock that are duly converted in accordance herewith or repurchased or otherwise acquired by the Corporation shall revert to authorized but unissued shares of Preferred Stock, undesignated as to series and available for future issuance; provided that any such cancelled shares of Series A Preferred Stock may be reissued only as shares of any series of Preferred Stock other than Series A Preferred Stock.

SECTION 15. Voting Rights .

(a) General . Holders shall not have any voting rights in respect of their shares of Series A Preferred Stock except as set forth below or as otherwise from time to time required by law or the Charter. Except as provided herein with respect to voting rights allocated pro rata with other classes or series of Parity Stock based on the liquidation preference of each such class or series, Holders will be entitled to one vote for each such share on any matter on which Holders are entitled to vote, including any action by written consent.

(b) Preferred Directors . Whenever, at any time or times, dividends payable on the shares of Series A Preferred Stock have not been paid for an aggregate of six or more Dividend Periods, whether or not consecutive (an “ Event of Non-payment ”), the Holders will have the right, with holders of shares of any one or more other classes or series of outstanding Parity Stock upon which like voting rights have been conferred and are exercisable at the time, voting together as a class (and with voting rights allocated pro rata based on the liquidation preference of each such class or series), to elect two directors (together, the “ Preferred Directors ”

28

and each, a “ Preferred Director ”) at the next annual meeting or special meeting of the Corporation’s stockholders and at each subsequent annual meeting or special meeting of the Corporation’s stockholders until all accrued and unpaid dividends have been paid in full or fully set aside for payment on Series A Preferred Stock, at which time such right will terminate, except as otherwise provided herein or expressly provided by law, subject to revesting in the event of each and every Event of Non-payment; provided that it will be a qualification for election for any Preferred Director that the election of such Preferred Director will not cause the Corporation to violate any corporate governance requirements of any securities exchange or other trading facility on which the Corporation’s securities may then be listed or traded that listed or traded companies, including that the Corporation have a majority of independent directors.

Upon any termination of the right set forth in the immediately preceding paragraph, the Preferred Directors shall cease to be qualified as directors, the term of office of all Preferred Directors then in office shall terminate immediately and the authorized number of directors shall be reduced by the number of Preferred Directors elected as described above.

Any Preferred Director may be removed at any time, with or without cause, and any vacancy created thereby may be filled, only at a meeting of the Corporation’s stockholders at which this is a permitted action by the affirmative vote of the Holders of a majority in voting power of the shares of Series A Preferred Stock at the time outstanding voting separately as a class together with the holders of shares of Parity Stock upon which like voting rights have been conferred and are exercisable at the time (and with voting rights allocated pro rata based on the liquidation preference of each such class or series), to the extent the voting rights of such Holders described above are then exercisable. If the office of any Preferred Director becomes vacant for any reason other than removal from office as described above, the remaining Preferred Director may choose a successor who will hold office for the unexpired term in respect of which such vacancy occurred.

At any time after the right of Holders to elect Preferred Directors has become vested and is continuing but a meeting of the Corporation’s stockholders to elect such Preferred Directors has not yet been held, or if a vacancy shall exist in the office of any such Preferred Director that has not been filled by the remaining Preferred Director, the Board of Directors may, but shall not be required to, call a special meeting of Holders and the holders of any one or more classes or series of outstanding Parity Stock upon which like voting rights have been conferred and are exercisable at the time, for the purpose of electing the Preferred Directors that such Holders and holders are entitled to elect; provided that in the event the Board of Directors does not call such special meeting, such election will be held at the next annual meeting. At any such meeting held for the purpose of electing such Preferred Director or Preferred Directors, as the case may be, (whether at an annual meeting or special meeting), the presence in person or by proxy of the Holders and holders of shares representing at least a majority of the voting power of the Series A Preferred Stock and any Parity Stock having similar voting rights shall be required to constitute a quorum of the Series A Preferred Stock and any Parity Stock having similar voting rights. The affirmative vote of Holders and the holders of any Parity Stock having similar voting rights constituting a majority of the voting power of such shares present at such meeting, in person or by proxy, shall be sufficient to elect any such Preferred Director.

(c) Voting Rights as to Particular Matters . So long as any shares of Series A Preferred Stock are outstanding, in addition to any other vote or consent of stockholders required by law or by the Charter, the affirmative vote or consent of the Holders of at least two-thirds in voting power of the shares of Series A Preferred Stock at the time outstanding and all other Parity Stock having similar voting rights that are exercisable at the time (subject to the last paragraph of this Section 15(c)), voting together as a single class (and with voting rights allocated pro rata based on the liquidation preference of each such class or series), given in person or by proxy, either by vote at any meeting called for such purpose, or by written consent in lieu of such meeting, shall be necessary for effecting or validating:

(i) Authorization of Senior Stock . Any amendment or alteration of this Certificate of Designations or the Charter to authorize or create or increase the authorized amount of, or any issuance of, any shares of, or any securities convertible into or exchangeable or exercisable for shares of, any class or series of capital stock of the Corporation ranking senior to Series A Preferred Stock with respect to either or both the payment of dividends and/or the distribution of assets on any liquidation, dissolution or winding up of the Corporation (“ Senior Stock ”);

29

(ii) Amendment of Series A Preferred Stock . Any amendment, alteration or repeal of any provision of this Certificate of Designations or the Charter (including, unless no vote on such merger or consolidation is required by Section 15(c)(iii), any amendment, alteration or repeal by means of a merger, consolidation or otherwise) so as to adversely affect the rights, preferences, privileges or voting powers of the Series A Preferred Stock; or

(iii) Share Exchanges, Reclassifications, Mergers and Consolidations . Any consummation of a binding share exchange, a reclassification involving the Series A Preferred Stock, or a merger or consolidation of the Corporation with or into another corporation or other entity, unless in each case (x) the Series A Preferred Stock remains outstanding or, in the case of any such merger or consolidation with respect to which the Corporation is not the surviving or resulting entity, is converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent, and (y) the Series A Preferred Stock remaining outstanding or such new preference securities, as the case may be, have such rights, preferences, privileges and voting powers, and limitations and restrictions thereof, taken as a whole, as are not materially less favorable to the holders thereof than the rights, preferences, privileges and voting powers, and limitations and restrictions thereof, of Series A Preferred Stock immediately prior to such consummation, taken as a whole;

provided , however , that for all purposes of this Section 15(c), the creation and issuance, or an increase in the authorized or issued amount, whether pursuant to pre-emptive or similar rights or otherwise, of any series of Preferred Stock, or any securities convertible into or exchangeable or exercisable for any other series of Preferred Stock (including the Series A Preferred Stock), ranking equally with and/or junior to Series A Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and the distribution of assets upon liquidation, dissolution or winding up of the Corporation shall not be deemed to adversely affect the rights, preferences, privileges or voting powers, and shall not require the affirmative vote or consent of, the Holders.

If any amendment, alteration, repeal, share exchange, reclassification, merger or consolidation specified in this Section 15(c) would adversely affect one or more but not all series of Parity Stock (including the Series A Preferred Stock for this purpose), then only the one or more series of Parity Stock adversely affected and entitled to vote, rather than all series of Parity Stock, shall vote as a class.

(d) Procedures for Voting and Consents . The rules and procedures for calling and conducting any meeting of Holders (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules the Board of Directors, in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Charter, the Bylaws, applicable law and the rules of any national securities exchange or other trading facility on which the Series A Preferred Stock is listed or traded at the time.

SECTION 16. Record Holders . To the fullest extent permitted by applicable law, the Corporation and the Transfer Agent may deem and treat the Record Holder of any share of Series A Preferred Stock as the absolute, true and lawful owner thereof for all purposes, including, without limitation, for purposes of making payment and settling conversions, to the fullest extent permitted by law and neither the Corporation nor the Transfer Agent shall be affected by any notice to the contrary.

SECTION 17. Notices . All notices or communications in respect of Series A Preferred Stock shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Certificate of Designations, the Charter, the Bylaws or by applicable law. Notwithstanding the foregoing, if shares of Series A Preferred Stock are issued in book-entry form through DTC or any similar facility, such notices may be given to the Holders in any manner permitted by such facility.

30

SECTION 18. No Pre-emptive Rights; No Redemption Right . No share of Series A Preferred Stock or share of Common Stock issued upon conversion of the Series A Preferred Stock shall have any rights of preemption whatsoever as to any securities of the Corporation, or any warrants, rights or options issued or granted with respect thereto, regardless of how such securities, or such warrants, rights or options, may be designated, issued or granted. The Series A Preferred Stock is not redeemable.

SECTION 19. Replacement Stock Certificates .

(a) If physical certificates are issued, and any of the Series A Preferred Stock certificates shall be mutilated, lost, stolen or destroyed, the Corporation shall, at the expense of the Holder thereof, issue, in exchange and in substitution for and upon cancellation of the mutilated Series A Preferred Stock certificate, or in lieu of and substitution for the lost, stolen or destroyed Series A Preferred Stock certificate, a new Series A Preferred Stock certificate of like tenor and representing an equivalent amount of shares of Series A Preferred Stock, but only upon receipt of evidence of such loss, theft or destruction of such Series A Preferred Stock certificate and indemnity, if requested, satisfactory to the Corporation and the Transfer Agent.

(b) The Corporation is not required to issue any certificate representing the Series A Preferred Stock on or after the Mandatory Conversion Date (subject to postponement as described in Section 5(a)). In lieu of the delivery of a replacement certificate following the Mandatory Conversion Date (subject to postponement as described in Section 5(a)), the Transfer Agent, upon delivery of the evidence and indemnity described in clause (a) above, shall deliver the shares of Common Stock issuable, along with any other consideration payable or deliverable, pursuant to the terms of the Series A Preferred Stock formerly evidenced by the certificate.

SECTION 20. Transfer Agent, Registrar, Conversion and Dividend Disbursing Agent . The duly appointed Transfer Agent, Registrar, Conversion and Dividend Disbursing Agent for the Series A Preferred Stock shall be American Stock Transfer & Trust Company, LLC. The Corporation may, in its sole discretion, remove the Transfer Agent in accordance with the agreement between the Corporation and the Transfer Agent; provided that the Corporation 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 Corporation shall send notice thereof by first-class mail, postage prepaid, to the Holders.

SECTION 21 . Form .

(a) The Series A Preferred Stock shall be issued in the form of one or more permanent global shares of Series A Preferred Stock in definitive, fully registered form eligible for book-entry settlement with the global legend (the “ Global Shares Legend ”) as set forth on the form of Series A Preferred Stock certificate attached hereto as Exhibit A (each, a “ Global Preferred Share ”), which is hereby incorporated in and expressly made part of this Certificate of Designations. The Global Preferred Shares may have notations, legends or endorsements required by law, stock exchange rules, agreements to which the Corporation is subject, if any, or usage ( provided that any such notation, legend or endorsement is in a form acceptable to the Corporation). The Global Preferred Shares shall be deposited on behalf of the Holders represented thereby with the Registrar, at its New York office as custodian for DTC (the “ Depositary ”), and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Corporation and countersigned and registered by the Registrar as hereinafter provided. The aggregate number of shares represented by each Global Preferred 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.

This Section 21(a) shall apply only to a Global Preferred Share deposited with or on behalf of the Depositary. The Corporation shall execute and the Registrar shall, in accordance with this Section 21(a), countersign and deliver any Global Preferred Shares that (i) shall be registered in the name of Cede & Co. or

31

other nominee of the Depositary and (ii) shall be delivered by the Registrar to Cede & Co. or pursuant to instructions received from Cede & Co. or held by the Registrar as custodian for the Depositary pursuant to an agreement between the Depositary and the Registrar. Members of, or participants in, the Depositary (“ Agent Members ”) shall have no rights under this Certificate of Designations with respect to any Global Preferred Share held on their behalf by the Depositary or by the Registrar as the custodian of the Depositary, or under such Global Preferred Share, and the Depositary may be treated by the Corporation, the Registrar and any agent of the Corporation or the Registrar as the absolute owner of such Global Preferred Share for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Corporation, the Registrar or any agent of the Corporation 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 Preferred Share. The Holder of the Global Preferred Shares may grant proxies or otherwise authorize any Person to take any action that a Holder is entitled to take pursuant to the Global Preferred Shares, this Certificate of Designations or the Charter.

Owners of beneficial interests in Global Preferred Shares shall not be entitled to receive physical delivery of certificated shares of Series A Preferred Stock, unless (x) the Depositary notifies the Corporation that it is unwilling or unable to continue as Depositary for the Global Preferred Shares and the Corporation does not appoint a qualified replacement for the Depositary within 90 days or (y) the Depositary ceases to be a “clearing agency” registered under the Exchange Act and the Corporation does not appoint a qualified replacement for the Depositary within 90 days. In any such case, the Global Preferred Shares shall be exchanged in whole for definitive stock certificates that are not issued in global form, with the same terms and of an equal aggregate Liquidation Preference, and such definitive stock certificates shall be registered in the name or names of the Person or Persons specified by the Depositary in a written instrument to the Registrar.

(b) Signature . Two Officers permitted by applicable law shall sign each Global Preferred Share for the Corporation, in accordance with the Corporation’s Bylaws and applicable law, by manual or facsimile signature. If an Officer whose signature is on a Global Preferred Share no longer holds that office at the time the Registrar countersigned such Global Preferred Share, such Global Preferred Share shall be valid nevertheless. A Global Preferred Share shall not be valid until an authorized signatory of the Registrar manually countersigns such Global Preferred Share. Each Global Preferred Share shall be dated the date of its countersignature. The foregoing paragraph shall likewise apply to any certificate representing shares of Series A Preferred Stock.

SECTION 22. Stock Transfer and Stamp Taxes . The Corporation shall pay any and all stock transfer and documentary stamp taxes that may be payable in respect of any issuance or delivery of shares of Series A Preferred Stock or shares of Common Stock or other securities issued on account of Series A Preferred Stock pursuant hereto or certificates representing such shares or securities. The Corporation 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 shares of Series A Preferred Stock or Common Stock or other securities in a name other than that in which the shares of Series A Preferred Stock 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 Holder thereof, and shall not be required to make any such issuance, delivery or payment unless and until the Person otherwise entitled to such issuance, delivery or payment has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid or is not payable.

SECTION 23 . Listing . The Corporation hereby covenants and agrees that, if its listing application for the Series A Preferred Stock is approved, upon such listing, the Corporation shall use its reasonable best efforts to keep the Series A Preferred Stock listed on the New York Stock Exchange.

If the Global Preferred Share or Global Preferred Shares, as the case may be, or the Series A Preferred Stock represented thereby shall be listed on the New York Stock Exchange or any other stock exchange, the Depositary may, with the written approval of the Corporation, appoint a registrar (acceptable to the Corporation) for registration of such Global Preferred Share or Global Preferred Shares, as the case may be, or the Series A

32

Preferred Stock represented thereby in accordance with the requirements of such exchange. Such registrar (which may be the Registrar if so permitted by the requirements of such exchange) may be removed and a substitute registrar appointed by the Registrar upon the request or with the written approval of the Corporation. If the Global Preferred Share or Global Preferred Shares, as the case may be or the Series A Preferred Stock represented thereby are listed on one or more other stock exchanges, the Registrar will, at the request and expense of the Corporation, arrange such facilities for the delivery, transfer, surrender and exchange of such Global Preferred Share or Global Preferred Shares, as the case may be, or the Series A Preferred Stock represented thereby as may be required by law or applicable stock exchange regulations.

SECTION 24. Ranking. Notwithstanding anything in this Certificate of Designations to the contrary, the Series A Preferred Stock will, with respect to dividend rights or rights upon the liquidation, winding-up or dissolution of the Corporation rank (i) senior to any Junior Stock, (ii) on parity with any Parity Stock and (iii) junior to any Senior Stock and the Corporation’s existing and future indebtedness (including trade payables).

SECTION 25. Other Rights . The shares of Series A Preferred Stock shall not have any rights, preferences, privileges or voting powers or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth herein or in the Charter or as provided by applicable law.
