4. The Amended Certificate of Incorporation authorizes the issuance of up to 100,000,000 shares of preferred stock, par value $0.01 per share, of the Company (“Preferred Stock”), and expressly authorizes the Board of Directors of the Company, to authorize the issuance of Preferred Stock from time to time in one or more classes or series, and with respect to each series of Preferred Stock, to fix and state by the resolution or resolutions from time to time adopted by the Board of Directors of the Company providing for the issuance thereof the designation and the powers, preferences, rights, qualifications, limitations and restrictions related to each series of Preferred Stock.

5. Pursuant to the authority conferred upon the Board of Directors of the Company by the Amended Certificate of Incorporation and pursuant to the provisions of Sections 103 and 151(g) of the DGCL, the Board of Directors of the Company, at a duly convened meeting on June 12, 2019, adopted resolutions (the “Authorizing Resolutions”) appointing a Transaction Committee of the Board of Directors of the Company (the “Transaction Committee”) to exercise all powers and authority of the Board of Directors of the Company to, among other things, authorize and approve a certificate of designations of rights and preferences with respect to a new series of Preferred Stock designated as Series A Perpetual Preferred Stock of the Company, and in such certificate of designations of rights and preferences to establish, fix, state and express the designations, rights, preferences, powers, restrictions and limitations of the Series A Preferred Stock.

Section 2. Dividends.

(a) Base Dividend Rate. Holders of shares of the Series A Preferred Stock are entitled to receive, when, as and if declared by the Board of Directors of the Company, out of funds legally available for the payment of dividends, cumulative cash dividends per share (the “Initial Fixed Dividends”) equal to the annual rates (the “Base Dividend Rate”), expressed as percentages of the Liquidation Preference, during the periods beginning on (i) the Issue Date, in the case of the Initial Fixed Dividends payable for the period commencing in 2019, and (ii) September 30 of each other year indicated below, and ending on September 29 of the next succeeding year (each such period, a “Fixed Dividend Period”), subject to the provisions of Section 2(c):

(b)Contingent Dividends. Prior to the date of the consummation of a P2 Company Acquisition (the “P2 Company Acquisition Date”), holders of shares of Series A Preferred Stock are entitled to receive, when, as and if declared by the Board of Directors of the Company, cumulative cash dividends equal to 12.6% of any P2 Distribution, pro rata per share (the “Contingent Dividends”); provided, however, that the Contingent Dividends payable pursuant to this Section 2(b) shall not exceed, in the aggregate, $3.25 per share of Series A Preferred Stock (the “Contingent Dividend Cap”). On and after the P2 Company Acquisition Date, holders of shares of Series A Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors of the Company, out of funds legally available for the payment of dividends, cumulative cash dividends per share (the “Additional Fixed Dividends” and together with the Initial Fixed Dividends, the “Fixed Dividends”, and the Fixed Dividends, together with the Contingent Dividends, “Dividends”) in an amount equal to the following annual rates, expressed as percentages of the Remaining Contingent Dividend Cap (as determined on the P2 Company Acquisition Date): (i) if the P2 Company Acquisition Date occurs in the Fixed Dividend Period beginning in either 2019 or 2020, 20.000% in such Fixed Dividend Period and in each subsequent Fixed Dividend Period until and including the Fixed Dividend Period beginning in 2024; (ii) if the P2 Company Acquisition Date occurs in the Fixed Dividend Period beginning in 2021, 25.000% in such Fixed Dividend Period and in each subsequent Fixed Dividend Period until and including the Fixed Dividend Period beginning in 2024; (iii) if the P2 Company Acquisition Date occurs in the Fixed Dividend Period beginning in 2022, 33.333% in such Fixed Dividend Period and in each subsequent Fixed Dividend Period until and including the Fixed Dividend Period beginning in 2024; (iv) if the P2 Company Acquisition Date occurs in the Fixed Dividend Period beginning in 2023, 50.000% in such Fixed Dividend Period and in the next succeeding Fixed Dividend Period beginning in 2024; and (v) if the P2 Company Acquisition Date occurs in the Fixed Dividend Period beginning in 2024 or later, 100.000% in the Fixed Dividend Period in which the P2 Company Acquisition Date occurs; provided, however, that the sum of (x) all Contingent Dividends accrued prior to the P2 Company Acquisition Date and (y) Additional Fixed Dividends shall not exceed the Contingent Dividend Cap.

(c) Certain Adjustments to the Base Dividend Rate Upon the Occurrence of a Permitted Change of Control. (i) Upon the occurrence of a Permitted Ratings Downgrade Change of Control, if in any Fixed Dividend Period, the rating from each of S&P and Moody’s in respect of the Company is at or below any of the applicable ratings set forth in the immediately following table in this clause (i), the applicable Base Dividend Rate for such Fixed Dividend Period, and for each subsequent Fixed Dividend Period for so long as the Series A Preferred Stock are outstanding, shall automatically increase such that it will be equal to (1) the applicable Base Dividend Rate for such Fixed Dividend Period, and the Base Dividend Rate in each subsequent Fixed Dividend Period, plus (2) the amount set forth opposite the lower of the two ratings by S&P and Moody’s in the table below (subject to clause(iii) of this Section 2(c)):

2

Rating (Moody’s / S&P)	Increase in Base Dividend Rate
B1 / B+	25 basis points
B2 / B	50 basis points
B3 / B-	75 basis points
Caa1 / CCC+ or below	100 basis points

For the avoidance of doubt, if, following any such modification to the Base Dividend Rate pursuant to this clause(i), the ratings of S&P and Moody’s subsequently change to a different rating in any Fixed Dividend Period, there shall be no further modification to the applicable Base Dividend Rate for such Fixed Dividend Period. The adjustments provided for in this Section 2(c)(i) shall not apply in a Permitted Private Change of Control.

(ii) Following a Permitted Private Change of Control, the Base Dividend Rate applicable for the Fixed Dividend Period in which such Permitted Private Change of Control occurs shall automatically increase by seventy-five (75) basis points beginning on the date of the occurrence of such Permitted Private Change of Control, and such increased Base Dividend Rate shall continue to apply for the remaining portion of such Fixed Dividend Period, and the Base Dividend Rate in each subsequent Fixed Dividend Period, shall increase by seventy-five (75) basis points until the Fixed Dividend Period beginning on September 30, 2024, at which point the Base Dividend Rate shall increase to 7.775% and shall remain at such level thereafter; provided that (1) the initial seventy-five (75) basis point increase in the Base Dividend Rate provided by the foregoing clause shall be reduced to an increase of twenty-five (25) basis points (x) immediately, in the case of a P2 Company Acquisition that precedes or is concurrent with such Permitted Private Change of Control, or (y) beginning on the date of the P2 Company Acquisition, in the case of a P2 Company Acquisition that occurs subsequent to such Permitted Private Change of Control and (2) such increased Base Dividend Rate described in the preceding proviso (1) shall continue to apply for the remaining portion of such Fixed Dividend Period, and the Base Dividend Rate in each subsequent Fixed Dividend Period, shall increase by twenty-five (25) basis points until the Fixed Dividend Period beginning on September 30, 2025, at which point the Base Dividend Rate shall increase to 7.775% and shall remain at such level thereafter. For the avoidance of doubt, the adjustments provided for in this Section 2(c)(ii) shall not apply in a Permitted Ratings Downgrade Change of Control.

(iii) In the case of the occurrence of an event that is both a Permitted Private Change of Control and a Permitted Ratings Downgrade Change of Control, then the modification to the applicable Base Dividend Rate for the Fixed Dividend Period shall be the modification as provided by clause(ii) of this Section 2(c) for such Fixed Dividend Period, and not clause(i) of this Section 2(c).

(d) Dividend Payment Date; Dividend Record Date.

(i) Fixed Dividends. The Initial Fixed Dividends shall accrue from, and including, the date of original issuance (the “Issue Date”), and the Additional Fixed Dividends shall accrue from, and including, the P2 Company Acquisition Date, in each case, compounded quarterly. (1) The Initial Fixed Dividends shall be payable (x) for the period from, and including, the Issue Date to, but not including, January 31, 2020 and (y) beginning on January 31, 2020, for each quarterly period thereafter (each, a “Quarterly Dividend Period”), and (2) the Additional Fixed Dividends shall be payable (x) for the period from, and including, the P2 Company Acquisition Date to, but not including, the beginning date of next succeeding Quarterly Dividend Period and (y) for each Quarterly Dividend Period thereafter, until no further Additional Fixed Dividends are payable pursuant to Section 2(b); each such dividend period for Initial Fixed Dividends and/or Additional Fixed Dividends (including the initial dividend periods) are herein referred to as a “Dividend Period”. Fixed Dividends shall be paid on the last day of each January, April, July and October of the applicable Dividend Period (each such payment date, a “Dividend Payment Date”), commencing on January 31, 2020 (in the case of Initial Fixed Dividends) and the beginning date of the Quarterly Dividend Period next succeeding the P2 Company Acquisition Date (in the case of Additional Fixed Dividends); provided that if any Dividend Payment Date is not a Business Day, then the Dividend which would otherwise have been payable on that Dividend Payment Date may be paid on the next succeeding Business Day, and no interest, additional dividends or other sums will

3

accrue on the amount so payable for the period from and after that Dividend Payment Date to that next succeeding Business Day. Any Fixed Dividends payable on the Series A Preferred Stock, including dividends payable for any partial Dividend Period, shall be computed on the basis of a 360-day year consisting of twelve 30-day months. Fixed Dividends shall be payable to holders of record as they appear in the stock records of the Company or the Transfer Agent, as applicable, for the Series A Preferred Stock at the close of business on the applicable record date, which shall be 15th day of each January, April, July and October, whether or not a Business Day, in the applicable Dividend Period (each, a “Dividend Record Date”).

(ii) Contingent Dividends. The Contingent Dividends shall accrue upon the receipt by the Company or any of its subsidiaries of any P2 Distribution (a “P2 Payment Date”) and shall be paid no later than 10 Business Days after the next regularly scheduled meeting of the Company’s Board of Directors following such P2 Payment Date, not to exceed 90 days following the P2 Payment Date (the “Contingent Dividend Payment Date”). The Contingent Dividends shall be payable to holders of record as they appear in the stock records of the Company or the Transfer Agent, as applicable, for the Series A Preferred Stock at the close of business on the applicable record date, which shall be the P2 Payment Date, whether or not a Business Day. For the avoidance of doubt, any Contingent Dividends that accrue prior to the P2 Company Acquisition Date shall be payable pursuant to this clause (ii), whether or not the Contingent Dividend Payment Date is on or after the P2 Company Acquisition Date.

(e) Dividend Accrual. The Dividends on the Series A Preferred Stock shall accrue on a day-to-day basis from, and including, the first day of each Dividend Period (in the case of Fixed Dividends) or upon receipt by the Company or any of its subsidiaries of each P2 Distribution (in the case of Contingent Dividends), until such Dividends are paid pursuant to Section 2(d). Notwithstanding any provisions of this Certificate to the contrary, Dividends shall accrue regardless of whether (i) the terms of any Senior Stock the Company may issue or agreements the Company may enter into, including any documents governing the indebtedness of the Company, at any time prohibit the current payment of dividends; (ii) the Company has earnings; (iii) there are funds legally available for the payment of such Dividends; or (iv) such Dividends are declared by the Board of Directors of the Company. Holders of the Series A Preferred Stock shall not be entitled to any dividends in excess of the Dividends described above. Any dividend payment made on the Series A Preferred Stock in respect of Fixed Dividends or Contingent Dividends shall first be credited against the Accumulated Fixed Dividends or the Accumulated Contingent Dividends, as applicable, with respect to those shares.

(f) Dividends on Junior Stock or Parity Stock. Unless full Accumulated Dividends on the Series A Preferred Stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof is set apart for payment for all Accumulated Dividends, (x) no dividends (other than in shares of Junior Stock) shall be declared or paid or set aside for payment upon shares of any Junior Stock or Parity Stock the Company may issue, nor shall any other dividend be declared or made upon such shares of Junior Stock or Parity Stock; and (y) no shares of any Junior Stock or Parity Stock shall be redeemed, purchased or otherwise acquired for any consideration (or any moneys paid to or made available for a sinking fund for the redemption of any such shares) by the Company (except as mandatorily required by the terms of such equity security or by conversion into or exchange for shares of Junior Stock the Company may issue); provided, that no provision in this Certificate shall be deemed to restrict or prohibit the acquisition by the Company of Junior Stock in connection with the receipt of shares of such Junior Stock upon (A) the “net” or “cashless” exercise of options to purchase shares of Junior Stock for purposes of exercising such options or (B) vesting of Restricted Stock Awards, including in each case the payment of taxes due as a result of such exercise or vesting.

(g) Pro Rata Dividends. When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series A Preferred Stock and the shares of any Parity Stock, all dividends declared upon the Series A Preferred Stock and any Parity Stock shall be declared pro rata so that the amount of dividends declared per share of Series A Preferred Stock and such other Parity Stock shall in all cases bear to each other the same ratio that accrued dividends per share on the Series A Preferred Stock and such other Parity Stock (which shall not include any accrual in respect of unpaid dividends for prior Dividend Periods if such Parity Stock does not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Series A Preferred Stock which may be in arrears.

Section 3. Liquidation Preference. Upon the voluntary or involuntary liquidation, dissolution or winding up of the Company’s affairs (a “Liquidation Event”), then, before any distribution or payment shall be made to the holders of any shares of Class A Common Stock, par value $0.01 per share, of the Company (the “Common Stock”) or any other class or series of Junior Stock, each holder of Series A Preferred Stock shall be entitled to receive, for each of such holder’s shares of Series A Preferred Stock, out of the Company’s assets legally available for distribution to stockholders, liquidating distributions or payments in the amount of the Liquidation Preference, plus an amount equal to the sum of all Accumulated Dividends as of the date of such Liquidation Event. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series A Preferred Stock shall have no right or claim to any of the Company’s remaining assets. In the event that, upon any such Liquidation Event, the Company’s available assets are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series A Preferred Stock and the corresponding amounts payable on all Senior Stock and Parity Stock, then after payment of the liquidating distribution on all outstanding Senior Stock, the holders of the Series A Preferred Stock and all other such classes or series of Parity Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. For such purposes, any consolidation or merger of the Company with or into any other entity, or the sale, lease or conveyance of all or substantially all of the property or business of the Company, or a statutory share exchange shall not be deemed to constitute a Liquidation Event.

Section 4. Redemption.

(a) Optional Redemption; Optional Share Conversion. On or after October 25, 2024, and subject to clause (d) of Section 5, the Company may, at its option, upon not less than 45 and no more than 90 days written notice to holders of shares of the Series A Preferred Stock, either:

(i) redeem for cash the Series A Preferred Stock (an “Optional Redemption”), (A) in whole at any time or from time to time or (B) in part at any time or from time to time, provided that at least 25% of the aggregate amount of Series A Preferred Stock issued under this Certificate remains outstanding immediately after the occurrence of such partial redemption, in each case, at a redemption price per share of Series A Preferred Stock to be redeemed equal to the sum of:

(1) 101.000% of the Liquidation Preference of such share of Series A Preferred Stock; plus

(2) Accumulated Dividends, if any, on such share of Series A Preferred Stock as of the applicable date of Optional Redemption; plus

(3) an amount equal to (x) the Contingent Dividend Cap, less (y) the sum of (A) all Contingent Dividends and Additional Fixed Dividends previously paid (if any) on such share of Series A Preferred Stock prior to the applicable date of Optional Redemption, and (B) all Accumulated Contingent Dividends and Accumulated Additional Fixed Dividends as of the applicable date of Optional Redemption (such sum pursuant to clauses (a)(i)(1), (2) and (3), the “Optional Redemption Price”); or

(ii) cause the outstanding shares of Series A Preferred Stock to be converted, (A) in whole at any time or from time to time or (B) in part at any time or from time to time, provided that at least 25% of the aggregate amount of Series A Preferred Stock issued under this Certificate remains outstanding immediately after the occurrence of such partial conversion, in each case, into the number of whole, fully-paid and non-assessable shares of Common Stock for each share of Series A Preferred Stock equal, subject to clause (c) of this Section 4, to the Optional Share Conversion Rate, with cash payment for fractional shares based on the applicable Reference Price (the “Optional Share Conversion”); provided, that notwithstanding the foregoing, the Company may not effect an Optional Share Conversion following the occurrence of a Permitted Private Change of Control.

(b) Holder Optional Redemption. Following the occurrence of a Permitted Private Change of Control, each holder of shares of Series A Preferred Stock, may, on the fifteenth anniversary of the Issue Date and each anniversary thereafter for so long as any shares of Series A Preferred Stock remain outstanding (each, a “Potential Holder Optional Redemption Date”), require the Company to redeem for cash the Series A Preferred Stock (a “Holder Optional Redemption”) of each of such holder, in whole or in part, at a redemption price per share of Series A Preferred Stock to be redeemed equal to the Change of Control Premium (the “Holder Optional Redemption Price”).

5

(c) Share Caps. Notwithstanding Section 4(a)(ii), no share of Series A Preferred Stock may be converted into shares of Common Stock pursuant to an Optional Share Conversion if such Optional Share Conversion would result in (i) any holder of Series A Preferred Stock obtaining shares of Common Stock, which when added together with such holder’s other shares of Voting Stock of the Company, would exceed the Voting Share Cap (a “Voting Share Cap Violation”) and/or (ii) the Company issuing an aggregate number of shares of Common Stock in excess of the Aggregate Share Cap (an “Aggregate Share Cap Violation” and together a Voting Share Cap Violation, each, a “Share Cap Violation”); provided that if any Optional Share Conversion would result in a Share Cap Violation, the Company must either, at its election, (1) subject to Section 4(a)(i)(B) and (a)(ii)(B), reduce the number of shares of Series A Preferred stock subject to the Optional Share Conversion so as to avoid the Share Cap Violation or (2) redeem for cash the shares of Series A Preferred Stock that, if converted into shares of Common Stock, would result in the Share Cap Violation, in each case, at the Optional Redemption Price per share of Series A Preferred Stock to be redeemed pursuant to Section 4(a). If the terms of any Optional Share Conversion are required to be amended pursuant to the preceding sentence following the mailing of the notice of Optional Share Conversion, then such amended terms shall be communicated to holders in the manner specified in Section 4(d), but in no event fewer than fifteen (15) days prior to the original conversion date (it being understood that the conversion date may be delayed as contemplated in Section 4(d)).

(d) Redemption and Conversion Procedures.

(i) Notice of an Optional Redemption or Optional Share Conversion shall be mailed at least forty-five (45) days but not more than ninety (90) days before the redemption or conversion date, as applicable, to each holder of record of Series A Preferred Stock at the address shown on the share transfer books of the Company or the Transfer Agent, as applicable. Each notice shall state: (i) the redemption or conversion date, as applicable; (ii) the number of shares of Series A Preferred Stock to be redeemed or converted, as applicable; (iii) if fewer than all outstanding shares of Series A Preferred Stock are to be redeemed or converted, the number of shares of Series A Preferred Stock to be redeemed or to be converted, as applicable, from each such holder, including, as applicable, to avoid a Share Cap Violation; (iv) (A) in the case of an Optional Redemption, the Optional Redemption Price and (B), in the case of an Optional Share Conversion, the Optional Share Conversion Rate and the amount of any cash payment for fractional shares; (v) the place or places where certificates issued for Series A Preferred Stock, if any, are to be surrendered for payment of the Optional Redemption Price or conversion into shares of Common Stock pursuant to the Optional Share Conversion, as applicable; (vi) that dividends on the Series A Preferred Stock will cease to accrue on the date of Optional Redemption or Optional Share Conversion, as applicable; and (vii) any other information required by law. If an Optional Redemption or Optional Share Conversion is subject to satisfaction of one or more conditions precedent, the applicable redemption or conversion notice shall describe such condition, and if applicable, shall state that, in the Company’s discretion, the redemption or conversion date may be delayed until such time as any or all such conditions shall be satisfied, without the requirement of an additional notice period to the holders of Series A Preferred Stock, or such Optional Redemption or Optional Share Conversion may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the date of Optional Redemption or Optional Share Conversion, or by the date of Optional Redemption or Optional Share Conversion date as so delayed.

(ii) Within ten (10) Business Days of a receipt of a notice of Optional Share Conversion, each holder of record of Series A Preferred Stock shall provide a certification to the Company substantially in the form of Exhibit D hereto.

(iii) At the Company’s election, on or prior to the redemption date in connection with an Optional Redemption, the Company may irrevocably deposit the aggregate Optional Redemption Price of the Series A Preferred Stock so called for redemption in trust for the holders thereof with a bank or trust company, in which case the notice to holders of shares of Series A Preferred Stock will (i) state the date of such deposit, (ii) specify the office of such bank or trust company as the place of payment of the Optional Redemption Price, and (iii) require such holders to surrender certificates issued for shares of Series A Preferred Stock, if any, at such place on or about the date fixed in such redemption notice (which may not be later than such redemption date) against payment of the Optional Redemption Price. Any interest or other earnings earned on the aggregate Optional Redemption Price deposited with a bank or trust company shall be paid to the Company. Any monies so deposited that remain unclaimed by the holders of shares of Series A Preferred Stock at the end of one year after the redemption date shall be returned to the Company by such bank or trust company. If the Company makes such a deposit, shares of Series A Preferred Stock

6

shall not be considered outstanding for purposes of voting or determining shares entitled to vote on any matter on or after the date of such deposit.

(iv) On or after the date fixed for Optional Redemption or Optional Share Conversion, each holder of shares of Series A Preferred Stock must present and surrender each certificate representing his or her Series A Preferred Stock, if any, to the Company at the place designated in the applicable notice and thereupon, (A) in the case of an Optional Redemption, the Optional Redemption Price of such shares shall be paid to or on the order of the person whose name appears on the certificate or Ownership Notice, as applicable, representing the Series A Preferred Stock as the owner thereof and (B) in the case of an Optional Share Conversion, the shares of Common Stock into which such shares of Series A Preferred Stock shall be converted pursuant to the Optional Share Conversion shall be issued to the person whose name appears on the certificate or Ownership Notice, as applicable, representing the Series A Preferred Stock as the owner thereof.

(v) Notice of a Holder Optional Redemption shall be mailed at least forty-five (45) days but not more than ninety (90) days before the redemption date to the Company.

Within ten (10) Business Days of a receipt of a notice of Holder Optional Redemption, the Company shall provide the Holder Optional Redemption Price by written notice to the redeeming holders of Series A Preferred Stock. On or prior to the redemption date in connection with a Holder Optional Redemption, the Company may irrevocably deposit the aggregate Holder Optional Redemption Price of the Series A Preferred Stock so called for redemption in trust for the holders thereof with a bank or trust company, in which case the notice to holders of shares of Series A Preferred Stock will (i) state the date of such deposit, (ii) specify the office of such bank or trust company as the place of payment of the Holder Optional Redemption Price, and (iii) require such holders to surrender certificates issued for shares of Series A Preferred Stock, if any, at such place on or about the date fixed in such redemption notice (which may not be later than such redemption date) against payment of the Holder Optional Redemption Price.

(a) Change of Control Conversion Right. Upon the occurrence of a Change of Control Event, each holder of Series A Preferred Stock shall have the option, during the applicable Change of Control Conversion Period, to convert any or all of its shares of Series A Preferred Stock on the Change of Control Conversion Date into the amount of Reference Property such holder would have received had such holder, immediately prior to the Change of Control, converted such shares of Series A Preferred Stock into the number of shares of Common Stock equal to the Change of Control Conversion Rate, with cash payment for fractional shares based on the applicable Change of Control Conversion Price (the “Change of Control Conversion”).

Holders of shares of Series A Preferred Stock may withdraw any notice of exercise of the right to a Change of Control Conversion (in whole or in part) by a written notice of withdrawal delivered to the Transfer Agent prior to the close of business on the Business Day prior to the Change of Control Conversion Date. The notice of withdrawal must state:

• the number of withdrawn shares of Series A Preferred Stock;

• the certificate numbers, if any, of the withdrawn shares of Series A Preferred Stock; and

• the number of shares of Series A Preferred Stock, if any, which remain subject to the Exercise Notice.

(d) Effect of Optional Redemption or Optional Share Conversion Notice on Change of Control Conversion. In the event that the Company issues a notice of Optional Redemption or Optional Share Conversion after the issuance of a Change of Control Event Notice, and if the Optional Redemption Price would be less than the otherwise applicable Holder Optional Redemption Price (as though the Holder Optional Redemption right had been exercised) calculated as though the proposed Optional Redemption Date were a Potential Holder Optional Redemption Date, or the Optional Share Conversion Rate would be less than the otherwise applicable Change of Control Conversion Rate, as applicable, in each case as calculated pursuant to Sections 4 and 5 (as applicable), then the Optional Redemption Price shall be re-calculated to be equal to such otherwise applicable Holder Optional Redemption Price and the Optional Share Conversion Rate shall be re-calculated to be equal to such otherwise applicable Change of Control Conversion Rate, as applicable. Any notice of Optional Redemption or Optional Share Conversion shall be irrevocable. If the Company provides a notice of Optional Redemption or Optional Share Conversion as described in Section 4, holders of shares of Series A Preferred Stock shall not have any right to exercise their right to a Change of Control Conversion in respect of such shares of Series A Preferred Stock that the Company has so elected to redeem or convert or subsequently selected for redemption or conversion, as applicable, and any such shares of Series A Preferred Stock that have been surrendered pursuant to the Change of Control Conversion shall be redeemed or converted on the related date of redemption or conversion, as applicable, instead of purchased on the Change of Control Conversion Date, and the holders of such shares shall be entitled to receive on the applicable redemption or conversion date the Optional Redemption Price and, or the number of shares of Common Stock pursuant to the Optional Share Conversion, as applicable, in either case, as may be re-calculated as provided for in the first sentence of this Section 5(d).

Section 6. Status of Acquired Shares. All shares of Series A Preferred Stock redeemed by the Company or subject to conversion in accordance with Sections 4 and 5 hereof, or otherwise acquired by the Company, shall be cancelled and the amount of such shares restored to the status of authorized but unissued shares of undesignated Preferred Stock of the Company.

Section 7. Ranking.The Series A Preferred Stock will rank: (i) senior to the Common Stock and any class or series of capital stock expressly stated to be junior to the Series A Preferred Stock (collectively, “Junior Stock”); (ii) junior to any class or series of the Company’s capital stock expressly stated to be senior to the Series A Preferred Stock (collectively, “Senior Stock”); and (iii) equally with each other class or series of Preferred Stock the Company may issue that is not expressly stated to be junior to the Series A Preferred Stock (collectively, “Parity Stock”), in each case of clauses (i)-(iii) above, with respect to the payment of dividends and the distribution of assets upon the Company’s liquidation, dissolution or winding up.

Section 8. Voting Rights.

(a) Voting. Holders of Series A Preferred Stock shall be entitled to vote on all matters on which the holders of shares of Common Stock are entitled to vote and, except as otherwise provided herein, in the Certificate of Incorporation, or by law, the holders of Series A Preferred Stock shall vote together with the holders of shares of Common Stock and any other shares of capital stock of the Company entitled to vote thereon as a single class. As of any record date or other determination date for any such vote, each holder of Series A Preferred Stock shall be entitled to a number of votes equal to the number of votes such holder would have had if all shares of Series A Preferred Stock held by such holder on such date had been converted into shares of Common Stock immediately prior thereto on a one-to-one (1:1) basis (subject to appropriate and customary adjustment(s) in the event of a stock split, stock dividend, combination or other similar recapitalization and ignoring all fractional votes). Notwithstanding the foregoing, the voting rights of the holders of Series A Preferred Stock in the aggregate shall not

9

in any event exceed the Voting Cap (without giving effect to any such holder’s other shares of Voting Stock of the Company). To the extent the voting rights of holders of Series A Preferred Stock are so limited by the Voting Cap, the vote of all holders of Series A Preferred Stock shall be reduced on a pro rata basis.

(b) Amendments. (i) Unless the Company has received the approval of two-thirds (2/3) of the votes entitled to be cast by the holders of outstanding Series A Preferred Stock, voting separately as a class (with each share of Series A Preferred Stock entitled to one (1) vote), either at a meeting of holders of Series A Preferred Stock or by written consent, the Company will not amend, alter or repeal any provisions of this Certificate whether by merger, consolidation or otherwise, to affect adversely the rights, preferences, privileges or voting powers of the holders of the Series A Preferred Stock.

(ii) For purposes of the foregoing voting requirements, the following shall not be deemed to adversely affect the rights, preferences or voting powers of the Series A Preferred Stock:

• the amendment of this Certificate or any stock certificate representing shares of the Series A Preferred Stock: (1) to cure any ambiguity, omission, inconsistency or mistake in any such instrument in a manner that is not inconsistent with the provisions of this Certificate and that does not adversely affect the rights, preferences, privileges or voting powers of the Series A Preferred Stock or any holder in its capacity as such; (2) to make any provision with respect to matters or questions relating to the Series A Preferred Stock that is not inconsistent with the provisions of this Certificate and that does not adversely affect the rights, preferences, privileges or voting powers of the Series A Preferred Stock or any holder in its capacity as such; or (3) to make any other change that does not adversely affect the rights, preferences, privileges or voting powers of the Series A Preferred Stock or any holder in its capacity as such (other than with respect to any holder that consents to such change).

(c) Other Limitations on Voting Rights. The above voting provisions shall not apply with respect to any shares of Series A Preferred Stock if, at or before the time when the act with respect to which the vote would otherwise be required is effected, such shares of Series A Preferred Stock are subject to a notice of Optional Redemption pursuant to the provisions in Section 4 above and funds sufficient to pay the Optional Redemption Price for all of such shares

10

of Series A Preferred Stock called for redemption have been set aside for payment in accordance with the provisions of Section 4(d)(iii).

(d)Limitations on Future Issuances. Neither the Company nor any successor entity thereto shall issue any additional shares of Series A Preferred Stock or any Senior Stock (or equivalent securities issued by any such successor entity) without the consent of two-thirds (2/3) of the votes entitled to be cast by the holders of outstanding Series A Preferred Stock (or equivalent securities issued by any such successor entity). For the avoidance of doubt, the Company and any successor entity thereto shall be permitted to issue debt and any equity that is junior to or pari passu with the Series A Preferred Stock (including Junior Stock and Parity Stock (for the avoidance of doubt, not including any additional shares of Series A Preferred Stock)) (or equivalent securities issued by any such successor entity).

(v) Replacement Certificates. If any of the Series A Preferred Stock certificates shall be mutilated, lost, stolen or destroyed, the Company shall 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 Series A Preferred Stock certificate lost, stolen or destroyed, 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 Company and the Transfer Agent.

(vi) Cancellation. In the event the Company shall purchase or otherwise acquire Certificated Series A Preferred Stock (including upon conversion pursuant to Section 4 or 5), the same shall thereupon be delivered to the Transfer Agent for cancellation. The Transfer Agent and no one else shall cancel and destroy all Series A Preferred Stock certificates surrendered for transfer, exchange, conversion, replacement or cancellation and deliver a certificate of such destruction to the Company unless the Company directs the Transfer Agent to deliver canceled Series A Preferred Stock certificates to the Company. The Company may not issue new Series A Preferred Stock certificates to replace Series A Preferred Stock certificates to the extent they evidence Series A Preferred Stock which the Company has purchased or otherwise acquired (including upon conversion pursuant to Section 4 or 5).

(iii) Prior to due presentment for registration of transfer or exchange of any shares of Series A Preferred Stock, the Transfer Agent and the Company may deem and treat the Person in whose name such shares of Series A Preferred Stock are registered as the absolute owner of such Series A Preferred Stock and neither the Transfer Agent nor the Company shall be affected by notice to the contrary.

(iv) No service charge shall be made to a holder for any registration of transfer or exchange of any Series A Preferred Stock or Common Stock issued upon the conversion thereof on the transfer books of the Company or the Transfer Agent or upon surrender of any Series A Preferred Stock certificate or Common Stock certificate at the office of the Transfer Agent maintained for that purpose. However, the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Series A Preferred Stock or Common Stock, or the issuance or delivery of any Common Stock upon conversion of Series A Preferred Stock, if the Person receiving shares in connection with such transfer or exchange or conversion is not the holder thereof.

15

(d) No Obligation of the Transfer Agent. The Transfer Agent shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Certificate or under applicable law with respect to any transfer of any interest in any Series A Preferred Stock other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Certificate, and to examine the same to determine substantial compliance as to form with the express requirements hereof.
