WABASH NATIONAL CORPORATION

* * * *

Adopted in accordance with the provisions of Section 151(g) of the

General Corporation Law of the State of Delaware

* * * *

Richard J. Giromini, being the President and Chief Executive Officer of Wabash National Corporation, a corporation duly organized and existing under and by virtue of the General Corporation Law of the State of Delaware, DOES HEREBY CERTIFY as follows:

FIRST: The name of the corporation is Wabash National Corporation (the “Corporation”).

SECOND: The Certificate of Incorporation, as amended, of the Corporation (the “Certificate of Incorporation”) authorizes the issuance of 25,000,000 shares of Preferred Stock, par value $0.01 per share, of the Corporation and expressly vests in the Board of Directors of the Corporation (the “Board”) the authority provided therein to issue all of said shares in one or more series and by resolution or resolutions, the designation, number, full or limited voting powers, or the denial of voting powers, preferences and relative, participation, optional, or other special rights, qualifications, limitations or restrictions of each series to be issued.

THIRD: The Board, pursuant to the authority expressly vested by the Certificate of Incorporation, as amended, has adopted the following resolution creating Series E Redeemable Preferred Stock:

“Be it resolved, that the issuance of Series E Redeemable Preferred Stock, par value $0.01 per share, of the Corporation is hereby authorized, and the designation, voting powers, preferences and relative, participating, optional and other special rights, and qualifications, limitations and restrictions thereof, of the shares of such series, in addition to those set forth in the Certificate of Incorporation of the Corporation, are hereby fixed as follows:

A. Designation of Series E Preferred Stock

Section 1. Designation. The distinctive serial designation of such series is “Series E Redeemable Preferred Stock” (“Series E Preferred”). Each share of Series E Preferred shall be identical in all respects to each other share of Series E Preferred. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in Article B.

Section 2. Number of Shares. The number of authorized shares of Series E Preferred shall be 20,000. Such number may from time to time be increased (but not in excess of the total number of authorized shares of Preferred Stock less the number of shares of Preferred Stock then outstanding) or decreased (but not below the number of shares of Series E Preferred then outstanding) by the Board. Shares of Series E Preferred that are redeemed, purchased or otherwise acquired by the Corporation, or converted into another series of Preferred Stock, shall be canceled and shall revert to authorized but unissued shares of Preferred Stock undesignated as to series.

Section 3. Dividends.

(a) General Obligation. The holders of the Series E Preferred shall be entitled to receive preferential dividends, when and as declared by the Board or any duly authorized committee thereof, out of funds legally available for payment of dividends, as provided in this Section 3. Such dividends shall be payable by the Corporation in an amount per share of Series E Preferred (each, a “Series E Preferred Share”) determined by multiplying the Dividend Rate times a fraction the numerator of which is the number of days in such Dividend Period and the denominator of which is three hundred sixty-five.

(b) Payment of Dividends. Dividends on the Series E Preferred shall be paid in cash and until paid shall be accrued as set forth in Section 3(d). All dividends paid pursuant to this Section 3(b) shall be paid in equal pro rata proportions to the holders entitled thereto.

(c) Dividend Rate. Except as otherwise provided herein, dividends on each Series E Preferred Share shall accrue on a daily basis at the rate of 15.0% per annum (as adjusted from time to time in accordance with the terms hereof, the “Dividend Rate”) of the sum of the Liquidation Value thereof and all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends) from and including the Issuance Date of such Series E Preferred Share. On August 3, 2014 and on the third day of each third month thereafter, the Dividend Rate shall increase by an additional 0.5%, subject to applicable usury laws. Such dividends shall accrue whether or not they have been declared and whether or not there are profits, surplus or other funds of the Corporation legally available for the payment of dividends, such dividends shall be cumulative and all accrued and unpaid dividends shall be fully paid or declared with funds irrevocably set apart for payment before any dividends, distributions, redemptions or other payments may be declared or paid with respect to any Junior Stock (except as otherwise expressly provided herein). The date on which the Corporation initially issues any Series E Preferred Share shall be deemed to be its date of issuance (the “Issuance Date”) regardless of the number of times transfer of such Series E Preferred Share is made on the stock records maintained by or for the Corporation and regardless of the number of certificates which may be issued to evidence such Series E Preferred Share.

(d) Dividend Payment Dates; Calculation of Dividend. Dividends shall be payable in cash quarterly in arrears when and as declared by the Board, or any duly authorized committee thereof, on March 31, June 30, September 30 and December 31 of each year (each, a “Dividend Payment Date”), commencing on September 30, 2009. If any Dividend Payment Date occurs on a day that is not a Business Day, any accumulated and accrued dividends otherwise payable on such Dividend Payment Date shall be paid on the next succeeding Business Day. Dividends shall be paid to the holders of record of the Series E Preferred as their names shall appear on the share register of the Corporation on the record date for such dividend. Dividends payable in any Dividend Period which is less than a full Dividend Period in length will be computed on the basis of a ninety-day quarterly period and actual days elapsed in such Dividend Period. Dividends on account of arrears for any past Dividend Periods may be declared and paid at any time to holders of record on the record date therefor. For any Dividend Period in which dividends are not paid in full in cash on the Dividend Payment Date first succeeding the end of such Dividend Period, then on such Dividend Payment Date such accrued and unpaid dividends shall be accumulated effective at the beginning of the Dividend Period succeeding the Dividend Period as to which such dividends were not paid and shall thereafter accrue additional dividends in respect thereof at the Dividend Rate until such accumulated, accrued and unpaid dividends (whether accrued with respect to the Liquidation Value or any previously accrued dividends) have been paid in full .

(e) Distribution of Partial Dividend Payments. For so long as any share of Series E Preferred remains outstanding, in the event that full dividends are not paid to the holders of all outstanding shares of Series E Preferred or any Parity Stock with the same dividend payment date or with a dividend payment date during a Dividend Period, and funds available for payment of dividends shall be insufficient to permit payment in full to the holders of Series E Preferred and holders of Parity Stock of the full preferential amounts to which they are then entitled, then the entire amount available for payment of dividends shall be distributed ratably among all such holders of Series E Preferred and holders of Parity Stock in proportion to the full amount to which they would otherwise be respectively entitled.

Section 4. Priority of Series E Preferred Shares on Dividends and Redemptions. So long as any shares of Series E Preferred remain outstanding, without the prior written consent of the holders of a majority of the outstanding Series E Preferred Shares, the Corporation shall not, nor shall it permit any Subsidiary to, redeem, purchase or otherwise acquire directly or indirectly any Junior Stock, nor shall the Corporation directly or indirectly pay or declare any dividend or make any distribution upon any Junior Stock, other than:

(a) subject to approval, to the extent required under the Investor Rights Agreement, purchases, redemptions or other acquisitions of shares of Junior Stock in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors or consultants; or

(b) the payment of any dividends in respect of Junior Stock where the dividend is in the form of the same stock as that on which the dividend is being paid.

Subject to the provisions set forth above in Sections 3 and 4 and the restrictions contained in the Investor Rights Agreement, dividends payable in cash, stock or otherwise, as may be determined by the Board or any duly authorized committee thereof, may be declared and paid on any Junior Stock and Parity Stock from time to time out of any assets legally available for such payment, and holders of Series E Preferred will not be entitled to participate in those dividends.

Section 5. Liquidation.

(a) Liquidation. Upon any liquidation, dissolution or winding up of the Corporation (whether voluntary or involuntary), each holder of Series E Preferred shall be entitled to be paid, before any distribution or payment is made upon any Junior Stock and subject to the rights of the holders of any Parity Stock upon liquidation and the rights of the Corporation’s creditors, an amount in cash equal to the aggregate Liquidation Value of all Series E Preferred Shares held by such holder (plus all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends)) and the holders of Series E Preferred shall not be entitled to any further payment or have any further right or claim to the Corporation’s assets. If, upon any such liquidation, dissolution or winding up of the Corporation, the Corporation’s assets to be distributed among the holders of Series E Preferred and all holders of any Parity Stock are insufficient to permit payment to such holders of the aggregate amount which they are entitled to be paid under this Section 5, then the entire assets available to be distributed to the Corporation’s stockholders shall be distributed pro rata among such holders of Series E Preferred and holders of Parity Stock in proportion to the full amounts to which such holders would otherwise be respectively entitled if all amounts thereon were paid in full. Not less than thirty days prior to the payment date stated therein, the Corporation shall mail written notice of any such liquidation, dissolution or winding up to each record holder of Series E Preferred, setting forth in reasonable detail the amount of proceeds to be paid with respect to each Series E Preferred Share in connection with such liquidation, dissolution or winding up.

(b) Residual Distributions. If the respective aggregate liquidating distributions to which all holders of Series E Preferred and all holders of any Parity Stock are entitled pursuant to Section 5(a) have been paid, the holders of Junior Stock shall be entitled to receive all remaining assets of the Corporation according to their respective rights and preferences.

(c) Merger, Consolidation and Sale of Assets Not Liquidation. For purposes of this Section 5, the merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Series E Preferred receive cash, securities or other property for their shares, 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 6. Redemptions.

(a) Optional Redemption.

(i) Except pursuant to Section 6 (b), the Corporation may not redeem the Series E Preferred prior to August 3, 2010. From and after August 3, 2010, the Corporation may at any time and from time to time redeem all or any portion of the Series E Preferred Shares then outstanding pursuant to this Section 6(a) (an “Optional Redemption”). Upon the consummation of any Optional Redemption, the Corporation shall pay to each holder of Series E Preferred a price per Series E Preferred Share (with respect to each Series E Preferred Share to be redeemed in such Optional Redemption, the “Optional Redemption Price”) equal to:

(A)

if such redemption occurs at any time after August 3, 2010 but on or prior to August 3, 2012, then 120% of the sum of the Liquidation Value thereof and all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends);

(B)

if such redemption occurs at any time after August 3, 2012 but on or prior to August 3, 2014, then 115% of the sum of the Liquidation Value thereof and all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends); and

(C)

if such redemption occurs at any time after August 3, 2014, then 100% of the sum of the Liquidation Value thereof and all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends);

provided that if a Change of Control occurs on or prior to the one-year anniversary of the date on which an Optional Redemption is consummated pursuant to this Section 6 (a)(i), then the Corporation shall, simultaneously with or prior to such Change of Control, pay to each holder of Series E Preferred an amount per share, in cash, equal to the positive difference, if any, between (1) the Change of Control Price that would have been payable had such prior redemption been consummated as a Mandatory Redemption pursuant to Section 6 (b), and (2) the applicable Optional Redemption Price.

(ii) The Corporation shall deliver notice of an Optional Redemption to the holders of Series E Preferred at least fifteen days prior to the date of such Optional Redemption (the “Optional Redemption Date”). Such notice shall state the Optional Redemption Date, the Optional Redemption Price, the number of shares of Series E Preferred to be redeemed, and the place or places where certificates for shares of Series E Preferred are to be surrendered to the Corporation for redemption by Series E Preferred holder, in the manner and at the place designated.

(iii) The number of Series E Preferred Shares to be redeemed from each holder thereof in an Optional Redemption pursuant to this Section 6(a) shall be the number of Series E Preferred Shares determined by multiplying the total number of Series E Preferred Shares to be redeemed times a fraction, the numerator of which shall be the total number of Series E Preferred Shares then held by such holder and the denominator of which shall be the total number of Series E Preferred Shares then outstanding.

(b) Mandatory Redemption.

(i) Immediately prior to or simultaneously with the occurrence of a Change of Control or at such later time as may be specified in writing by any holder of the Series E Preferred, the Corporation shall redeem (such redemption, the “Mandatory Redemption”), upon election in writing by such holder of Series E Preferred, all of the Series E Preferred then outstanding and pay to each holder of Series E Preferred a price per Series E Preferred Share (the “Change of Control Price”) equal to the Liquidation Value thereof (and the accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends)) plus a premium equal to 200% of the sum of (A) the Liquidation Value thereof and (B) all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends).

(ii) The Corporation shall provide each holder of Series E Preferred with not less than fifteen days’ written notice prior to the occurrence of a Change of Control (the date on which such Change of Control occurs, the “Mandatory Redemption Date”) or entering into an agreement providing for such Change of Control or, in the case of a Change of Control referred to in clause (ii) of the definition thereof pursuant to a tender offer of which the Corporation has no prior knowledge, promptly after the Corporation discovers that the Change of Control will occur or has occurred. Such notice shall describe in reasonable detail the material terms and the Mandatory Redemption Date (or anticipated timing, in the case of an agreement) to each holder of Series E Preferred, and the Corporation shall give each holder of Series E Preferred prompt written notice of any material change in the terms or timing of such transaction. Any such notice also shall state the Change of Control Price and that the holder is to surrender to the Corporation, at the place or places where certificates for shares of Series E Preferred are to be surrendered for redemption, in the manner and at the price designated, the certificate or certificates representing the shares of Series E Preferred to be redeemed.

(c) Mechanics of Redemption. Upon receipt of payment of the Optional Redemption Price (in the case of an Optional Redemption) or the Change of Control Price (in the case of the Mandatory Redemption) with respect to each Series E Preferred Share to be redeemed by the holders of Series E Preferred, each holder of Series E Preferred will deliver the certificate(s) evidencing the Series E Preferred to be redeemed by the Corporation, unless such holder is awaiting receipt of a new certificate evidencing such shares from the Corporation pursuant to another provision hereof.

(d) Dividends After Redemption Date. No Series E Preferred Share shall be entitled to any dividends accruing after the date on which Optional Redemption Price (in the case of an Optional Redemption) or the Change of Control Price (in the case of the Mandatory Redemption) of such Series E Preferred Share is paid to the holder of such Series E Preferred Share. On such date, all rights of the holder of such Series E Preferred Share shall cease, and such Series E Preferred Share shall no longer be deemed to be issued and outstanding.

Section 7. Other Rights.

(a) Board Representation.

(i) From and after the Effective Date until the Common Expiration Date, the Majority Trailer Investors may nominate five directors (collectively, the “Investor Directors”) to be elected to the Board. Any such nominee for Investor Director shall be subject to (A) the reasonable approval of the Board’s Nominating and Corporate Governance Committee (the “Governance Committee”) (such approval not to be unreasonably withheld, conditioned or delayed), and (B) satisfaction of all legal and governance requirements regarding service as a director of the Corporation; provided that the Corporation shall, at the reasonable request of the Majority Trailer Investors, so long as such request is not inconsistent with applicable law or exchange requirements, amend or modify any such requirements so as not to any way impede the right of the Majority Trailer Investors to nominate directors. On the Effective Date, the Corporation shall cause the five initial Investor Directors who are named in Section 4.1 of the Investor Rights Agreement to be elected and appointed to the Board. The Corporation from time to time shall take all actions necessary or reasonably required such that the number of members on the Board shall (1) except as otherwise provided herein, consist of no more than seven non-Investor Directors, and (2) if necessary, be increased such that there are sufficient seats on the Board for the Investor Directors to serve on the Board and such vacancies (the “Investor Director Seats”) shall be filled by the Investor Directors, effective as of the Effective Date (or, if later, then the date that the Majority Trailer Investors determine to appoint such Investor Directors). Each Investor Director appointed pursuant to this Section 7(a)(i) shall continue to hold office until such Investor Director’s term expires, subject, however, to prior death, resignation, retirement, disqualification or termination of term of office as provided in Section 7(a)(iii).

(ii) Prior to the Common Expiration Date, at each meeting of the Corporation’s stockholders at which the election of directors to the Investor Director Seats is to be considered, the Corporation shall, subject to the provisions of Section 7(a)(i) and Section 7(a)(iii), nominate the Investor Director(s) designated by the Majority Trailer Investors for election to the Board by the holders of voting capital stock and solicit proxies from the Corporation’s stockholders in favor of the election of Investor Directors. Subject to the provisions of Section 7(a)(i) and Section 7(a)(iii), the Corporation shall use all reasonable best efforts to cause each Investor Director to be elected to the Board (including voting all unrestricted proxies in favor of the election of such Investor Director and including recommending approval of such Investor Director’s appointment to the Board) and shall not take any action which would diminish the prospects of such Investor Director(s) of being elected to the Board.

(iii) The right of the Majority Trailer Investors to designate the Investor Directors pursuant to Section 7(a)(i) and Section 7(a)(ii) shall terminate on the Common Expiration Date. If the right of the Majority Trailer Investors to nominate Investor Directors terminates pursuant to the immediately preceding sentence, then each Investor Director shall promptly submit his or her resignation as a member of the Board and each applicable Sub Board with immediate effect.

(iv) Any elected Investor Director may resign from the Board at any time by giving written notice to the Board. The resignation is effective without acceptance when the notice is given to the Board, unless a later effective time is specified in the notice.

(v) So long as the Majority Trailer Investors retain the right to designate Investor Directors, the Corporation shall use all reasonable best efforts to remove any Investor Director only if so directed in writing by the Majority Trailer Investors.

(vi) In the event of a vacancy on the Board resulting from the death, disqualification, resignation, retirement or termination of term of office of an Investor Director nominated by the Majority Trailer Investors, the Corporation shall use all reasonable best efforts to fill such vacancy with a representative designated by the Majority Trailer Investors as provided hereunder, in either case, to serve until the next annual or special meeting of the stockholders (and at such meeting, such representative, or another representative designated by the Majority Trailer Investors, will be elected to the Board in the manner set forth in Section 7(a)(ii)).

(vii) The Investor Directors and the Board Observer, if any, shall be entitled to reimbursement of reasonable expenses incurred in such capacities, but shall not otherwise be entitled to any compensation from the Corporation in such capacities as Investor Directors or the Board Observer.

(viii) Until the Majority Trailer Investors cease to hold, or cease to “beneficially own” (within the meaning of Rule 13d-3 under the Exchange Act) at least 2% of the issued and outstanding Common Stock of the Corporation, the Majority Trailer Investors shall have the right to designate one non-compensated, non-voting observer (the “Board Observer”) to attend all meetings of the Board as an observer. The Board Observer shall not attend executive sessions or committee meetings without the consent of the majority of the members of the Board or committee members; provided that the Board Observer shall be entitled to attend all meetings of the Audit Committee. The Board Observer shall be entitled to notice of all meetings of the Board and the Audit Committee in the manner that notice is provided to members of the Board or the Audit Committee, as applicable, shall be entitled to receive all materials provided to members of the Board and the Audit Committee, shall be entitled to attend (whether in person, by telephone, or otherwise), subject to the restriction set forth in the immediately preceding sentence, all meetings of the Board and the Audit Committee as a non-voting observer.

(ix) Subject to (A) the reasonable approval of the Governance Committee (such approval not to be unreasonably withheld, conditioned or delayed), and (B) satisfaction of all legal and governance requirements regarding service as a director or member of any committee of the Corporation or any of its Subsidiaries, at the request of the Majority Trailer Investors, the Corporation shall cause the Investor Directors to have proportional representation (relative to their percentage on the whole Board, but in no event less than one representative) on the boards (or equivalent governing body) of each Subsidiary (each, a “Sub Board”), and each committee of the Board (other than the Audit Committee of the Board (the “Audit Committee”) to the extent prohibited by applicable law or exchange requirements but shall allow one representative to attend meetings of the Audit Committee as a non-voting observer) and each Sub Board. The Corporation shall at the reasonable request of the Majority Trailer Investors, so long as such request is not inconsistent with applicable law or exchange requirements, amend or modify any requirements regarding service as a director or member of any committee of the Corporation or any of its Subsidiaries.

(x) The Corporation shall purchase and maintain directors’ and officers’ liability insurance policy covering each Investor Director effective from the Effective Date (or such later date as such Investor Director is appointed pursuant to Section 7(a)(i) or Section 7(a)(ii)) and shall purchase and maintain for a period of not less than six years from the date of any Investor Director’s death, resignation, retirement, disqualification or termination of term of office as provided in Section 7(a)(iii), a directors’ and officers’ liability insurance tail policy for such Investor Director.

(b) Approval of the Majority Trailer Investors.

(i) From and after the Effective Date until the Preferred Expiration Date, the Corporation and the Board shall not, and shall take all action possible to ensure that each Subsidiary of the Corporation shall not, without the prior written consent of the Majority Trailer Investors (which consent may be withheld in their sole discretion) take any of the following actions or engage in any of the following transactions:

(B) authorize, issue or enter into any agreement providing for the issuance (contingent or otherwise) of (1) any notes or debt securities containing equity or voting features (including any notes or debt securities convertible into or exchangeable for capital stock or other equity securities, issued in connection with the issuance of capital stock or other equity securities or containing profit participation features) or (2) any capital stock, other equity securities or equity-linked securities (or any securities convertible into or exchangeable for any capital stock or other equity securities), except for the issuance of the Registrable Securities;

(C) make any loans or advances to, guarantees for the benefit of, or investments in, any Person (other than the Corporation or a wholly-owned direct or indirect Subsidiary of the Corporation), except for (1) reasonable advances to employees in the ordinary course of business consistent with past practice, (2) investments having a stated maturity no greater than one year from the date on which the Corporation or any of its Subsidiaries makes such investment in (a) obligations of the United States government or any agency thereof or obligations guaranteed by the United States government, (b) certificates of deposit of commercial banks having combined capital and surplus of at least $500 million and fully insured by the Federal Deposit Insurance Corporation, or (c) commercial paper with a rating of at least “Prime-1” by Moody’s Investors Service, Inc., and (3) investments expressly permitted pursuant to Section 7(b)(i)(E);

(D) liquidate, dissolve or effect a recapitalization or reorganization in any form of transaction (including any reorganization into a limited liability company, a partnership or any other non-corporate entity which is treated as a partnership for federal income tax purposes), unless, in the case of a recapitalization or reorganization, such transaction would result in a Change of Control and the Corporation pays to the holders of the Series E Preferred, the Series F Preferred and the Series G Preferred all amounts then due and owing under the Series E Preferred, the Series F Preferred and the Series G Preferred (including the premium payable in connection with any redemption relating to a Change of Control) prior to or contemporaneous with the consummation of such transaction;

(E) directly or indirectly acquire or enter into, or permit any Subsidiary to acquire or enter into, any interest in any Person, business or joint venture (in each case, whether by a purchase of assets, purchase of stock, merger or otherwise), except for acquisitions involving aggregate consideration (whether payable in cash or otherwise) not to exceed $5,000,000 in the aggregate if, at the time of any such acquisition, the Corporation and its Subsidiaries have availability for draw-downs under the Senior Loan Agreement in an amount equal to or exceeding $20,000,000 and the ratio of the aggregate Indebtedness of the Corporation and its Subsidiaries as of the most recent month end to the previous twelve-month EBITDA (as each such term is defined in the Senior Loan Agreement, as in effect on the Effective Date) (such ratio, the “Leverage Ratio”) after giving effect to such acquisition is less than 6:1;

(F) reclassify or recapitalize any securities of the Corporation or any of its Subsidiaries, unless such reclassification or recapitalization would result in a Change of Control and the Corporation pays to the holders of the Series E Preferred, the Series F Preferred and the Series G Preferred all amounts then due and owing under the Series E Preferred, the Series F Preferred and the Series G Preferred (including the premium payable in connection with any redemption relating to a Change of Control) prior to or contemporaneous with the consummation of such reclassification or recapitalization;

(e) Right Of First Refusal.

(i) From and after the Closing Date until the Preferred Expiration Date, the Trailer Investors shall have the right, at their election in accordance with this Section 7(e), to participate in any Subsequent Financing. The Trailer Investors may elect to provide all or any portion of the Subsequent Financing.

(ii) At least forty-five days prior to the anticipated consummation of any Subsequent Financing, the Corporation shall deliver a written notice (each, a “Subsequent Financing Notice”) to each Trailer Investor. The Subsequent Financing Notice shall disclose in reasonable detail the proposed terms and conditions of the Subsequent Financing, the amount of proceeds intended to be raised thereunder and the identity, and ownership of capital stock of the Corporation (if applicable), of any other prospective participants in such Subsequent Financing, and shall include a term sheet or similar document relating thereto as an attachment. The Subsequent Financing Notice shall constitute a binding offer to enter into the Subsequent Financing with each Trailer Investor on the terms and conditions set forth in such Subsequent Financing Notice.

(iii) Each Trailer Investor may elect to participate in such Subsequent Financing and shall have the right, subject to Section 7(e)(v) below, to fund all or any portion of the Subsequent Financing on the terms and subject to the conditions specified in the Subsequent Financing Notice by delivering written notice of such election to the Corporation within forty days after the delivery of the Subsequent Financing Notice to the Trailer Investors (the “Election Period”).

If the Trailer Investors fail to deliver such election notices prior to the end of the Election Period, then the Trailer Investors shall be deemed to have notified the Corporation that they do not elect to participate in such Subsequent Financing.

For purposes of clarity, (1) in the event that there is any amount of a Subsequent Financing that is not requested to be purchased by a Trailer Investor, then any other Trailer Investor shall have the right to purchase such remaining amount of the Subsequent Financing and (2) in no event shall the Trailer Investors have the right to purchase more than 100% of the amount the Subsequent Financing described in any Subsequent Financing Notice, in the aggregate. For purposes hereof, “Pro Rata Portion” means a fraction, the numerator of which is the Total Value of Securities held by a Trailer Investor participating under this Section 7(e)(iv), and the denominator of which is the sum of the aggregate Total Value of Securities held by all Trailer Investors participating under this Section 7(e)(iv).

(v) If any portion of a Subsequent Financing is not funded by the Trailer Investors or the Person identified in the Subsequent Financing Notice within sixty days after the delivery of the relevant Subsequent Financing Notice to the Trailer Investors on the same terms described in such Subsequent Financing Notice, then prior to consummating any subsequent Subsequent Financing, the Corporation must deliver a new Subsequent Financing Notice to the Trailer Investors and otherwise follow the procedures set forth in this Section 7(e) (and, for the avoidance of doubt, the Trailer Investors will again have the right of participation set forth above in this Section 7(e)).

(vi) Notwithstanding any other provision in this Certificate of Designation to the contrary, the Trailer Investors’ rights to participate in any Subsequent Financing shall be subject to such participation not causing a violation of the NYSE Limitation; provided, however, that the Corporation shall use all commercially reasonable efforts to discuss and explore ways to enable the Trailer Investors to participate in any Subsequent Financing in compliance with the NYSE Limitation.

(vii) Upon reasonable prior notice, the Corporation shall make available, during normal business hours, for inspection and review by the Trailer Investors and the representatives of and advisors to the Trailer Investors, all financial and other records, all SEC Filings and other filings with the SEC, and all other corporate documents and properties of the Corporation as may be reasonably necessary for the purpose of such review, and cause the Corporation’s officers, directors and employees, within a reasonable time period, to supply all such information reasonably requested by the Trailer Investors or any such representative or advisor, in each case, for the sole purpose of enabling the Trailer Investors and such representatives and advisors and their respective accountants and attorneys to conduct due diligence with respect to the Corporation in connection with such Subsequent Financing.

(viii) The Corporation shall not disclose material non-public information to the Trailer Investors, or to advisors to or representatives of the Trailer Investors, unless prior to disclosure of such information the Corporation identifies such information as being material non-public information and provides the Trailer Investors, such advisors and representatives with the opportunity to accept or refuse to accept such material non-public information for review and any Trailer Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Corporation with respect thereto; provided, however, that the foregoing shall not restrict the Corporation from disclosing material non-public information to any director or Board Observer, or to their advisors or representatives.

(b) Consequences of Events of Noncompliance.

(i) If any Event of Noncompliance has occurred and is continuing, then the dividend rate on the Series E Preferred from and after the occurrence of such Event of Noncompliance shall increase immediately by an additional 2.0% per annum, subject to applicable usury laws; provided, that if the Event of Noncompliance is related to the non payment of the cash dividends beginning with the September 30, 2011 Dividend Payment Date (whether or not the Corporation is legally able to pay the dividends), the dividend rate shall automatically increase to (A) the higher of (X) the then prevailing dividend rate and (Y) the then prevailing LIBOR rate plus 14.7% plus 2.0% per annum. Any increase of the dividend rate resulting from the operation of this subparagraph shall terminate as of the close of business on the date on which no Event of Noncompliance exists, subject to subsequent increases pursuant to this paragraph.

(ii) If any Specified Event of Noncompliance has occurred and is continuing, then the holder or holders of a majority of the Series E Preferred then outstanding may demand (by written notice delivered to the Corporation), subject to any limitations contained in the Senior Credit Agreement, immediate redemption of all or any portion of the Series E Preferred owned by such holder or holders at a price per Series E Preferred Share equal to the sum of the Liquidation Value thereof and all accumulated, accrued and unpaid dividends thereon (whether accrued with respect to the Liquidation Value or any previously accrued dividends). The Corporation shall give prompt written notice of such election to the other holders of Series E Preferred (but in any event within five days after receipt of the initial demand for redemption), and each such other holder may demand immediate redemption of all or any portion of such holder’s Series E Preferred by giving written notice thereof to the Corporation within seven days after receipt of the Corporation’s notice. The Corporation shall redeem all Series E Preferred as to which rights under this paragraph have been exercised within twenty days after receipt of the initial demand for redemption.

(iii) If any Event of Noncompliance exists, each holder of Series E Preferred shall also have any other rights which such holder is entitled to under any contract or agreement at any time and any other rights which such holder may have pursuant to applicable law.

Section 12. Registration of Transfer. The Corporation shall keep at its principal office a register for the registration of Series E Preferred Shares.

Each such new certificate shall be registered in such name and shall represent such number of Series E Preferred Shares as is requested by the holder of the surrendered certificate and shall be substantially identical in form to the surrendered certificate, and dividends shall accrue on the Series E Preferred Shares represented by such new certificate from the date to which dividends have been fully paid on such Series E Preferred Shares represented by the surrendered certificate.

Section 13. Record Holders. To the fullest extent permitted by applicable law, the Corporation and the transfer agent for Series E Preferred may deem and treat the record holder of any share of Series E Preferred as the true and lawful owner thereof for all purposes, and neither the Corporation nor such transfer agent shall be affected by any notice to the contrary.

Section 14. Replacement. Upon receipt of evidence reasonably satisfactory to the Corporation (an affidavit of the registered holder shall be satisfactory) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing shares of Series E Preferred, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Corporation (provided that if the holder is a financial institution or other institutional investor its own agreement shall be satisfactory), or, in the case of any such mutilation upon surrender of such certificate, the Corporation shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the number of shares of Series E Preferred represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate.

Section 15. Redeemed or Otherwise Acquired Shares. Any shares of Series E Preferred that are redeemed or otherwise acquired by the Corporation by reason of repurchase, conversion or otherwise shall be automatically and immediately canceled and shall revert to authorized but unissued shares of Preferred Stock, provided, that any such cancelled shares of Series E Preferred shall not be reissued, sold or transferred as shares of Series E Preferred.

Section 17. Specific Performance. The Corporation hereby acknowledges and agrees that the failure of the Corporation to perform its obligations hereunder, including its failure to pay dividends when due and payable, will cause irreparable injury to the holder of the Series E Preferred, for which damages, even if available, will not be an adequate remedy. Accordingly, the Corporation hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of the Corporation’s obligations and to the granting by any court of the remedy of specific performance of its obligations hereunder.

Section 18. No Preemptive Rights. Except as set forth in the Investor Rights Agreement, no share of Series E Preferred 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.

Section 19. Limitations under Senior Loan Agreement. Except for payments for which there is an express provision herein for restrictions related to the Senior Loan Agreement, in the event a payment is required to be made by the Corporation hereunder and such payment (or a portion thereof) would not be permitted to be paid pursuant to the terms of the Senior Loan Agreement, the Corporation shall not be in default with respect to non-payment of such payment or the portion thereof, in each case that is not so permitted (the “Deferred Portion”).
