4. Dividends.

(a) From and after the Effective Date, the Holders shall be entitled to receive, when, as and if declared by the Board of Directors or a duly authorized committee of the Board of Directors, out of funds legally available therefor, non-cumulative dividends of the type and in the amounts determined as set forth in Section 4(b) and cumulative dividends of the type and in the amounts determined as set forth in Section 4(c), and no more.

(b) Subject to Section 4(a), if the Board of Directors or a duly authorized committee of the Board of Directors declares and pays a cash dividend in respect of any Common Stock, then, and as a condition to such cash dividend, the Board of Directors or such duly authorized committee of the Board of Directors shall declare and pay to the Holders of the Series A Preferred Stock, on the same dates on which such cash dividend is declared or paid, as applicable, on such Common Stock, a cash dividend in an amount per share of Series A Preferred Stock equal to the product of (i) the per share dividend declared and paid in respect of each share of Common Stock and (ii) the number of shares of Common Stock into which such share of Series A Preferred Stock is then convertible, assuming receipt of the Stockholder Approval (such dividend a “Participating Dividend”).

(c) In addition to dividends payable under Section 4(b), dividends shall begin to accrue on August 30, 2013 and will be payable quarterly in arrears, commencing on September 30, 2013, when, as and if declared by the Board of Directors or a duly authorized committee of the Board of Directors, on March 31, June 30, September 30 and December 31 of each year, or, if any such day is not a Business Day, the next Business Day (each, a “Section 4(c) Dividend Payment Date”) for each outstanding share of Series A Preferred Stock, payable in cash at the Special Dividend Rate (such dividend, the “Special Dividend”). Dividends payable pursuant to this Section 4(c) will be, for each outstanding share of Series A Preferred Stock, payable in cash at an annual rate equal to the Special Dividend Rate multiplied by the sum of (A) the Liquidation Preference plus (B) all accrued and unpaid dividends, whether or not declared, on such shares of Series A Preferred Stock for any prior Section 4(c) Dividend Period, and will be computed on the basis of a 360-day year of twelve 30-day months and for any Section 4(c) Dividend Period greater or less than a full Section 4(c) Dividend Period will be computed on the basis of the actual number of days elapsed in the period divided by 360. No interest or sum of money in lieu of interest will be paid on any dividend payment on a share of Series A Preferred Stock paid later than the scheduled Section 4(c) Dividend Payment Date. The period from August 30, 2013 to but excluding September 30, 2013 and each period from and including a Section 4(c) Dividend Payment Date to but excluding the following Section 4(c) Dividend Payment Date is herein referred to as a “Section 4(c) Dividend Period.” Such dividends will accumulate during each dividend period from and including the immediately preceding dividend payment date (in the case of the initial dividend period, if applicable, August 30, 2013) to but excluding the immediately succeeding dividend payment date.

(d) Notwithstanding anything to the contrary, if the Corporation shall fail to pay any Participating Dividend or Special Dividend due under this Section 4, then the Special Dividend Rate thereafter shall automatically increase by 2% per annum.

5

(e) Each dividend will be payable to Holders of record as they appear in the records of the Corporation at the close of business on the applicable record date, which (i) with respect to Participating Dividends, shall be the same day as the record date for the payment of the corresponding dividends to the holders of shares of Common Stock and (ii) with respect to Special Dividends, shall be on the first Business Day of the month in which the relevant Section 4(c) Dividend Payment Date occurs (each, a “Record Date”).

(f) Special Dividends and Participating Dividends are cumulative on the Series A Preferred Stock. To the extent that the Board of Directors or a duly authorized committee of the Board of Directors does not declare and pay the Special Dividend in full on the Series A Preferred Stock for a Section 4(c) Dividend Period prior to the related Section 4(c) Dividend Payment Date or does not declare and pay a Participating Dividend when, as and if required by Section 4(b) during a Section 4(c) Dividend Period, such unpaid dividends shall accrue and shall cumulate from the scheduled Section 4(c) Dividend Payment Date for such Section 4(c) Dividend Period, shall compound on each subsequent Section 4(c) Dividend Payment Date and shall be payable quarterly in arrears on each subsequent Section 4(c) Dividend Payment Date. As used herein, the term “accrued” includes both accrued and accumulated dividends.

(g) If full dividends payable on Series A Preferred Stock pursuant to Section 4(b) for any dividend period or Section 4(c) for any Section 4(c) Dividend Period have not been declared and paid, or declared and a sum sufficient for the payment of those dividends been set aside, the Corporation may not: (i) declare and pay or set aside for payment or declare and make or set aside for payment any distribution of assets on any Junior Securities (other than a dividend payable solely in Junior Securities); (ii) repurchase, redeem, or otherwise acquire for consideration, directly or indirectly, any Junior Securities (other than as a result of a reclassification of Junior Securities for or into other Junior Securities, or the exchange or conversion of one Junior Security for or into another Junior Security, and other than through the use of the proceeds of a substantially contemporaneous sale of other Junior Securities), nor shall any monies be paid to or made available for a sinking fund for the redemption of any Junior Securities by the Corporation; or (iv) repurchase, redeem, or otherwise acquire for consideration, directly or indirectly, any Parity Securities otherwise than pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series A Preferred Stock and such Parity Securities except by conversion into or exchange for Junior Securities. The foregoing limitations do not apply to purchases or acquisitions of Junior Securities pursuant to any employee or director incentive or benefit plan or arrangement (including any of the Corporation’s employment, severance, or consulting agreements) of the Corporation or of any of its subsidiaries adopted before or after the Effective Date.

(h) If full dividends payable on Series A Preferred Stock pursuant to Section 4(b) for the current dividend period or Section 4(c) for any Section 4(c) Dividend Period have not been declared and paid, or declared and a sum sufficient for the payment of those dividends been set aside, the Corporation may not declare, pay, or set aside for payment dividends on any Parity Securities or Junior Securities for any period; provided, that to the extent that the Corporation declares dividends on the Series A Preferred Stock and on any Parity Securities but does not make full payment of such declared dividends, the Corporation will allocate the dividend payments on a pro rata basis among the Holders and the holders of any Parity Securities. For purposes of calculating the pro rata allocation of partial dividend payments, the Corporation will allocate dividend payments based on the ratio between the current and accrued dividends due on the shares of Series A Preferred Stock and the aggregate of the current and accrued dividends due on any Parity Securities, which shall not include any accumulation for any prior dividend periods if such Parity Securities do not have a cumulative dividend.

6

(i) If the Mandatory Conversion Date with respect to any share of Series A Preferred Stock is prior to any Record Date, the Holder of such share of Series A Preferred Stock (1) will not have the right to receive any Participating Dividends on the Series A Preferred Stock with respect to cash dividends declared on Common Stock on or after such Record Date and (2) will be entitled to receive a pro-rated Special Dividend with respect to the applicable Section 4(c) Dividend Period. If the Mandatory Conversion Date with respect to any share of Series A Preferred Stock is on or after the Record Date for any declared dividend and prior to the payment date for that dividend, the Holder thereof shall receive that dividend on the relevant payment date if such Holder was the Holder of record on the Record Date for that dividend. For the avoidance of doubt, this provision shall not affect any rights to receive any accrued but unpaid dividends on the Series A Preferred Stock attributable to any Section 4(c) Dividend Period completed prior to the Record Date or any Participating Dividends that prior to the Record Date became required to be declared pursuant to Section 4(b).

5. Liquidation.

(a) In the event the Corporation voluntarily or involuntarily liquidates, dissolves or winds up, or upon the occurrence of a Deemed Liquidation Event (as defined below) the Holders at the time shall be entitled to receive liquidating distributions in an amount equal to the greater of (i) the Liquidation Preference per share of Series A Preferred Stock, plus an amount equal to any accrued but unpaid dividends, whether or not declared, thereon to and including the date of such liquidation and (ii) 110.0% of the payment or distribution to which such Holders would be entitled if the Series A Preferred Stock were converted into Common Stock, assuming receipt of the Stockholder Approval, plus all accrued but unpaid dividends, whether or not declared, immediately before such liquidation, dissolution, winding-up or Deemed Liquidation Event, out of assets legally available for distribution to the Corporation’s stockholders, before any distribution of assets is made to the holders of the Common Stock or any other Junior Securities. After payment of the full amount of such liquidation distribution, the Holders shall not be entitled to any further participation in any distribution of assets by the Corporation.

(b) In the event the assets of the Corporation available for distribution to stockholders upon any liquidation, dissolution or winding-up of the affairs of the Corporation, whether voluntary or involuntary, or any Deemed Liquidation Event, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series A Preferred Stock and the corresponding amounts payable on any Parity Securities, Holders and the holders of such Parity Securities shall share ratably in any distribution of assets of the Corporation in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled.

(c) Each of the following events shall be considered a “Deemed Liquidation Event” unless at least 15 days prior to the effective date of any such event, Holders of a two-thirds majority of the issued and outstanding shares of Series A Preferred Stock elect, by vote at a duly constituted meeting or by written consent, to require such event to not be considered a Deemed Liquidation Event and the Corporation shall have delivered written notice of any such proposed event at least 30 days before the effective date thereof:

(i) a merger or consolidation in which the Corporation is a constituent party, or a subsidiary of the Corporation is a constituent party and the Corporation issues shares of its capital stock pursuant to such merger or consolidation, except any such merger

7

or consolidation involving the Corporation or a subsidiary in which the shares of capital stock of the Corporation outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or consolidation, at least a majority, by voting power, of the capital stock of (1) the surviving or resulting corporation or (2) if the surviving or resulting corporation is a wholly owned subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting corporation;

(ii) the sale, lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the Corporation or any subsidiary of the Corporation of all or substantially all the assets of the Corporation and its subsidiaries taken as a whole, or the sale or disposition (whether by merger or otherwise) of one or more subsidiaries of the Corporation if substantially all of the assets of the Corporation and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of the Corporation; or

(iii) whether in a single transaction or series of related, the sale, purchase or transfer to a person or group of affiliated persons of more than fifty percent (50%) of the then outstanding Common Stock to a person or group of affiliate persons who did not, immediately prior to such transaction or series of related transactions, own fifty percent (50%) or more of the then outstanding Common Stock.

If any such event occurs but shall not have been considered a Deemed Liquidation Event by a majority vote of the issued and outstanding shares of Series A Preferred Stock, such event shall be a deemed to be a Reorganization Event pursuant to Section 11.

6. Maturity. The Series A Preferred Stock shall be perpetual unless converted or redeemed in accordance with this Certificate of Designation.

7. Redemptions by the Corporation.

(a) Optional Redemption. The Series A Preferred Stock may not be redeemed by the Corporation prior to May 2, 2018. On or after May 2, 2018, the Corporation, at its option, may redeem at any time all, but not less than all, the shares of Series A Preferred Stock at the time outstanding, upon notice given as provided in Section 7(c) below, at a redemption price per share payable in cash equal to the greater of (i) 125.0% of the sum of (A) the Liquidation Preference, plus (B) all accrued but unpaid dividends up to, but excluding, the date fixed for redemption, whether or not declared, and (ii) 110.0% of (A) (x) the number of shares of Common Stock into which a share of Series A Preferred Stock would be convertible on the Trading Day immediately prior to the date fixed for redemption, assuming receipt of the Stockholder Approval, multiplied by (y) the Current Market Price of Common Stock on such Trading Day plus (B) all accrued but unpaid dividends up to, but excluding, the date fixed for redemption, whether or not declared. The redemption price for any shares of Series A Preferred Stock shall be payable on the redemption date to the Holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent. Any declared but unpaid dividends payable on a redemption date that occurs subsequent to a Record Date shall not be paid to the Holder entitled to receive the redemption price on the redemption date, but rather shall be paid to the holder of record of the redeemed shares on such Record Date.

(b) No Sinking Fund. The Series A Preferred Stock will not be subject to any mandatory redemption, sinking fund or other similar provisions. Holders of Series A Preferred Stock will have no right to require redemption of any shares of Series A Preferred Stock.

8

(c) Notice of Redemption. Notice of every redemption of shares of Series A Preferred Stock shall be given by first class mail, postage prepaid, addressed to the Holders of the shares to be redeemed at their respective last addresses appearing on the books of the Corporation. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption; provided, that failure to give such notice by mail, or any defect in such notice or in the mailing thereof, to any Holder of shares of Series A Preferred Stock designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Series A Preferred Stock to be so redeemed except as to the Holder to whom the Corporation has failed to give such notice or except as to the Holder to whom notice was defective. Notwithstanding the foregoing, if the Series A Preferred Stock or any depositary shares representing interests in the Series A Preferred Stock are issued in book-entry form through The Depository Trust Company or any other similar facility, notice of redemption may be given to the Holders of Series A Preferred Stock at such time and in any manner permitted by such facility. Each such notice given to a Holder shall state: (1) the redemption date; (2) the number of shares of Series A Preferred Stock to be redeemed and, if less than all the shares held by such Holder are to be redeemed, the number of such shares to be redeemed from such Holder; (3) the redemption price (or manner of determination of the redemption price); and (4) the place or places where certificates for such shares are to be surrendered for payment of the redemption price.

(d) Partial Redemption. In case of any redemption of only part of the shares of Series A Preferred Stock at the time outstanding, the shares to be redeemed shall be selected on a pro rata basis or such other method as the depositary shall require that approximates a pro rata basis. If fewer than all the shares represented by any certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without charge to the Holder thereof.

(e) Effectiveness of Redemption. If notice of redemption has been duly given as provided in Section 7(c) and if on or before the redemption date specified in the notice all funds necessary for the redemption have been set aside by the Corporation, separate and apart from its other funds, in trust for the pro rata benefit of the Holders of the shares called for redemption, so as to be and continue to be available therefor, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation, on and after the redemption date unless the Corporation defaults in the payment of the redemption price, in which case such rights shall continue until the redemption price is paid, dividends shall cease to accrue on all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the Holders thereof to receive the amount payable on such redemption, without interest. Any funds unclaimed at the end of two years from the redemption date shall, to the extent permitted by law, be released to the Corporation, after which time the Holders of the shares so called for redemption shall look only to the Corporation for payment of the redemption price of such shares. Shares of outstanding Series A Preferred Stock that are redeemed, purchased or otherwise acquired by the Corporation, or converted into other shares of capital stock of the Corporation, shall be cancelled and shall revert to authorized but unissued shares of the Corporation’s Preferred Stock undesignated as to series.

8. Mandatory Conversion.

(a) Effective as of the close of business on the Mandatory Conversion Date, each share of Series A Preferred Stock shall automatically convert into shares of Common Stock as set forth below. Upon conversion, Holders of Series A Preferred Stock may receive cash in lieu of fractional shares of Common Stock to the extent allowable pursuant to Section 13 hereof.

(b) The number of shares of Common Stock into which a share of Series A Preferred Stock shall be convertible shall be determined by dividing (x) the Liquidation Preference by (y) the Applicable Conversion Price (subject to the conversion procedures of Section 9 hereof), and a Holder shall receive a cash amount per share of Series A Preferred Stock equal to all accrued but unpaid dividends, whether or not declared, up to but not including the Mandatory Conversion Date.

9

9. Conversion Procedures.

(a) At any time after the Corporation has received the Stockholder Approval, the Corporation shall promptly provide a written demand of mandatory conversion to each Holder (such demand, a “Notice of Mandatory Conversion”). In addition to any information required by applicable law or regulation, the Notice of Mandatory Conversion with respect to such Holder shall state, as appropriate:

(i) the Mandatory Conversion Date;

(ii) the number of shares of Common Stock to be issued upon conversion of the Series A Preferred Stock held of record by such Holder and subject to such mandatory conversion; and

(iii) if certificates are to be issued, the place or places where certificates for shares of Series A Preferred Stock held of record by such Holder are to be surrendered for issuance of certificates representing shares of Common Stock, as applicable.

(b) Effective immediately prior to the close of business on the Mandatory Conversion Date with respect to any shares of Series A Preferred Stock, dividends shall no longer be declared on any such shares of Series A Preferred Stock and such shares of Series A Preferred Stock shall cease to be outstanding, in each case, subject to the right of the Holder to receive (i) shares of Common Stock issuable upon such mandatory conversion, (ii) any unpaid dividends, whether or not declared, on such shares to the extent provided in Section 4(i), and (iii) any other payments or distributions to which such Holder is otherwise entitled pursuant to Section 8, this Section 9, Section 10, Section 11 or Section 13 hereof, as applicable.

(c) No allowance or adjustment, except pursuant to Section 4 or Section 10, shall be made in respect of dividends payable to holders of the Common Stock of record as of any date prior to the close of business on the Mandatory Conversion Date with respect to any share of Series A Preferred Stock. Prior to the close of business on the Mandatory Conversion Date with respect to any share of Series A Preferred Stock, shares of Common Stock issuable upon conversion thereof, or other securities issuable upon conversion of, such share of Series A Preferred Stock shall not be deemed outstanding for any purpose, and the Holder thereof shall have no rights with respect to the Common Stock or other securities issuable upon conversion (including voting rights, rights to respond to tender offers for the Common Stock or other securities issuable upon conversion and rights to receive any dividends or other distributions on the Common Stock or other securities issuable upon conversion) by virtue of holding such share of Series A Preferred Stock, except to the extent provided in Section 4(b) or Section 10(d).

10

(d) Shares of Series A Preferred Stock duly converted in accordance with this Certificate of Designation, or otherwise reacquired by the Corporation, will resume the status of authorized and unissued shares of the Corporation’s Preferred Stock, undesignated as to series and available for future issuance. The Corporation may from time-to-time take such appropriate action as may be necessary to reduce the authorized number of shares of Series A Preferred Stock; provided, that the Corporation shall not take any such action if such action would reduce the authorized number of shares of Series A Preferred Stock below the number of shares of Series A Preferred Stock then outstanding.

(e) The Person or Persons entitled to receive the Common Stock and/or cash, securities or other property issuable upon conversion of Series A Preferred Stock shall be treated for all purposes as the record holder(s) of such shares of Common Stock and/or securities as of the close of business on the Mandatory Conversion with respect thereto. In the event that a Holder shall not by written notice designate the name in which shares of Common Stock and/or cash, securities or other property (including payments of cash in lieu of fractional shares) to be issued or paid upon conversion of shares of Series A Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Corporation shall be entitled to register and deliver such shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Corporation.

(f) Beginning on the Mandatory Conversion Date with respect to any share of Series A Preferred Stock, certificates representing shares of Common Stock shall be issued and delivered to the Holder thereof or such Holder’s designee (or, at the Corporation’s option, such shares shall be registered in book-entry form) upon presentation and surrender of the certificate evidencing the Series A Preferred Stock to the Corporation and, if required, the furnishing of appropriate endorsements and transfer documents and the payment of all transfer and similar taxes.

10. Anti-Dilution Adjustments.

(a) The Conversion Price shall be subject to the following adjustments:

(i) Stock Dividends and Distributions. If the Corporation pays dividends or other distributions on the Common Stock in shares of Common Stock, then the Conversion Price in effect immediately prior to the Ex-Date for such dividend or distribution will be multiplied by the following fraction:

Where,

If any dividend or distribution described in this clause (i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly

11

announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared (but giving effect to any intervening adjustments that may have been made with respect to the Series A Preferred Stock).

(ii) Subdivisions, Splits and Combinations of the Common Stock. If the Corporation subdivides, splits or combines the shares of Common Stock then the Conversion Price in effect immediately prior to the effective date of such share subdivision, split or combination will be multiplied by the following fraction:

Where,

If any subdivision, split or combination described in this clause (ii) is announced but the outstanding shares of Common Stock are not subdivided, split or combined, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to subdivide, split or combine the outstanding shares of Common Stock, to such Conversion Price that would be in effect if such subdivision, split or combination had not been announced (but giving effect to any intervening adjustments that may have been made with respect to Series A Preferred Stock).

(b) (i) All adjustments to the Conversion Price shall be calculated to the nearest 1/10 of a cent. No adjustment in the Conversion Price shall be required if such adjustment would be less than $0.01; provided, that any adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further that on the Mandatory Conversion Date adjustments to the Conversion Price will be made with respect to any such adjustment carried forward and which has not been taken into account before such date.

(ii) No adjustment to the Conversion Price shall be made if Holders are given at least 10 days’ prior notice of, and the opportunity to participate in, the transaction that would otherwise give rise to an adjustment, as a result of holding the Series A Preferred Stock (including without limitation pursuant to Section 4 hereof), without having to convert the Series A Preferred Stock, as if they held the full number of shares of Common Stock into which a share of the Series A Preferred Stock may then be converted.

(iii) The Applicable Conversion Price shall not be adjusted:

(A) upon the issuance of any shares of Common Stock pursuant to any present bona fide plan providing for the reinvestment of dividends or interest payable on the Corporation’s securities and the investment of additional optional amounts in shares of Common Stock under any such plan or under any bona fide savings or profit sharing or employee share purchase plan;

12

(B) upon the issuance of any shares of Common Stock or options, rights or warrants to purchase such shares pursuant to any present bona fide employee, director or consultant benefit or incentive plan or program of or assumed by the Corporation or any of its subsidiaries, the principal purpose of which is not to raise capital;

(C) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Effective Date and not amended in any economic or other relevant respect thereafter;

(D) for a change in the par value or no par value of Common Stock; or

(E) for accrued but unpaid dividends on the Series A Preferred Stock.

(c) Whenever the Conversion Price is to be adjusted in accordance with Section 10(a) or Section 10(b), the Corporation shall: (i) compute the Conversion Price in accordance with Section 10(a) or Section 10(b), taking into account the $0.01 threshold set forth in Section 10(b) hereof; (ii) as soon as practicable following the occurrence of an event that requires an adjustment to the Conversion Price pursuant to Section 10(a) or Section 10(b), taking into account the $0.01 threshold set forth in Section 10(b) hereof (or if the Corporation is not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and (iii) as soon as practicable following the determination of the revised Conversion Price in accordance with Section 10(a) or Section 10(b) hereof, provide, or cause to be provided, a written notice to the Holders setting forth in reasonable detail the method by which the adjustment to the Conversion Price was determined and setting forth the revised Conversion Price.

(d) The shares of Series A Preferred Stock shall also be entitled to the following rights:

(i) Issuance of Stock Purchase Rights. If the Corporation issues to all or substantially all holders of the shares of Common Stock rights or warrants (other than rights or warrants issued pursuant to a stockholders’ rights plan, a dividend reinvestment plan or employee share purchase plan or other similar plans) entitling them to subscribe for or purchase shares of Common Stock, then each Holder shall receive the same rights or warrants as a holder of Common Stock would receive as though such Holder’s shares of Series A Preferred Stock had been converted into such number of shares of Common Stock that such Holder’s shares of Series A Preferred Stock would then be convertible, assuming receipt of the Stockholder Approval.

(ii) Debt or Asset Distributions. If the Corporation distributes to all or substantially all holders of shares of Common Stock evidences of indebtedness, shares of capital stock, securities (including, without limitation, shares of capital stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in a “spin-off” transaction), cash or other assets (excluding any dividend or distribution referred to in clause (a)(i) above, any rights or warrants referred to in clause (d)(i) above, any dividend or distribution paid exclusively in cash, and any consideration payable in connection with a tender or exchange offer made by the Corporation or any of its applicable subsidiaries) (such evidences of

13

indebtedness, shares of capital stock, securities, cash or other assets, the “Distributed Property”), then each Holder shall receive the same distribution of Distributed Property as a holder of Common Stock would receive as though such Holder’s shares of Series A Preferred Stock had been converted into such number of shares of Common Stock that such Holder’s shares of Series A Preferred Stock would then be convertible, assuming receipt of the Stockholder Approval.

(iii) Cash Distributions. If the Corporation makes a distribution consisting exclusively of cash to all holders of the Common Stock, excluding (a) any cash dividend on the Common Stock to the extent a corresponding cash dividend pursuant to Section 4 is paid on the Series A Preferred Stock, (b) any cash that is distributed in a Reorganization Event, (c) any dividend or distribution in connection with the Corporation’s liquidation, dissolution or winding up, and (d) any consideration payable in connection with a tender or exchange offer made by the Corporation or any of its subsidiaries, then in each event, each Holder shall receive the same distribution as a holder of Common Stock would receive as though such Holder’s shares of Series A Preferred Stock had been converted into such number of shares of Common Stock that such Holder’s shares of Series A Preferred Stock would then be convertible, assuming receipt of the Stockholder Approval.

(iv) Self Tender Offers and Exchange Offers. If the Corporation or any of its subsidiaries successfully completes a tender or exchange offer for the Common Stock where the cash and the value of any other consideration included in the payment per share of the Common Stock exceeds the Current Market Price per share of the Corporation’s Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer (such excess, the “Excess Consideration”), then each Holder shall receive the same Excess Consideration as a holder of Common Stock participating in such tender or exchange offer would receive as though such Holder’s shares of Series A Preferred Stock had been converted into such number of shares of Common Stock that such Holder’s shares of Series A Preferred Stock would then be convertible, assuming receipt of the Stockholder Approval.

(v) Rights Plans. To the extent that the Corporation has a rights plan in effect with respect to the Common Stock on the Mandatory Conversion Date, upon conversion of any shares of the Series A Preferred Stock, Holders will receive, in addition to the shares of Common Stock, the rights under the rights plan, unless, prior to the Mandatory Conversion Date the rights have separated from the shares of Common Stock, in which case each Holder shall receive, at the time of separation, the same rights as if the Corporation had made a distribution to all holders of the Common Stock as described in clause (d)(i) above, assuming receipt of the Stockholder Approval

(e) Notwithstanding anything to the contrary in this Section 10 or otherwise in this Certificate of Designation, the Corporation shall not take any action that would result in the Applicable Conversion Price being adjusted to below the then par value of the Common Stock deliverable upon conversion of the Series A Preferred Stock.

11. Reorganization Events.

(a) In the event that for so long as any shares of Series A Preferred Stock remain outstanding there occurs, subject to Section 5:

(i) any consolidation, merger or other similar business combination of the Corporation with or into another Person, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Corporation or another Person;

14

(ii) any sale, transfer, lease or conveyance to another Person of all or substantially all of the property and assets of the Corporation, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Corporation or another Person;

(iii) any reclassification of the Common Stock into securities including securities other than the Common Stock; or

(iv) any statutory exchange of the outstanding shares of Common Stock for securities of another Person (other than in connection with a merger or acquisition); (any such event specified in this Section 11(a), a “Reorganization Event”); then each share of a Holder’s Series A Preferred Stock outstanding immediately prior to such Reorganization Event shall remain outstanding but shall automatically convert, effective as of the effective time and date of the Reorganization Event, into the type and amount of securities, cash and other property receivable in such Reorganization Event by a holder (excluding the counterparty to the Reorganization Event or an Affiliate of such counterparty ) of the number of shares of Common Stock specified below (such shares of Common Stock, the “Reorganization Event Shares”), and a cash amount to the extent provided below (such securities, cash and other property, the “Exchange Property”). The number of Reorganization Event Shares shall be determined by multiplying the number of shares of Series A Preferred Stock held by the Holder by the quotient of (x) the Liquidation Preference divided by (y) the Applicable Conversion Price as of such date, and a Holder shall receive a cash amount equal to all accrued but unpaid dividends on shares of Series A Preferred Stock held by such Holder, whether or not declared, with respect to any Section 4(c) Dividend Period for which a Record Date has occurred prior to the date of the Reorganization Event.

(b) In the event that holders of the shares of Common Stock have the opportunity to elect the form of consideration to be received in such transaction, the Holders shall likewise be allowed to make such an election.

(c) The above provisions of this Section 11 shall similarly apply to successive Reorganization Events and the provisions of Section 10 shall apply to any shares of capital stock of the Corporation (or any successor) received by the holders of the Common Stock in any such Reorganization Event.

(d) The Corporation (or any successor) shall, within seven days of the consummation of any Reorganization Event, provide written notice to the Holders of such consummation of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property. Failure to deliver such notice shall not affect the operation of this Section 11.

(e) The Corporation shall not enter into any agreement for a transaction constituting a Reorganization Event unless such agreement provides for or does not interfere with or prevent (as applicable) conversion of the Series A Preferred Stock into the Exchange Property in a manner that is consistent with and gives effect to this Section 11.

12. Voting Rights.

(a) Holders will not have any voting rights, including the right to elect any directors, except (i) voting rights, if any, required by law, and (ii) voting rights, if any, described in this Section 12.

15

(b) So long as any shares of Series A Preferred Stock are outstanding, the vote or consent of the Holders of at least a two-thirds majority of the shares of Series A Preferred Stock at the time outstanding, voting as a single voting group, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating any of the following actions, whether or not such approval is required by the Delaware General Corporation Law:

(i) any amendment, alteration or repeal (including by means of a merger, consolidation, operation of law or otherwise) of any provision of the Certificate of Incorporation, as amended (including this Certificate of Designation) or the Corporation’s bylaws that would adversely affect the rights or preference of the Series A Preferred Stock;

(ii) any amendment or alteration (including by means of a merger, consolidation, operation of law or otherwise) of the Corporation’s Certificate of Incorporation to authorize, or create, or increase the authorized amount of, any shares of, or any securities convertible into shares of, any Senior Securities;

(iii) any authorization or issuance of additional shares of Series A Preferred Stock;

(iv) any issuance of Parity Securities in excess of $2 million in aggregate principal amount.

(v) any issuance of Senior Securities; or

(vi) the consummation of a binding share exchange or reclassification involving the Series A Preferred Stock or a merger or consolidation of the Corporation with another entity that results in any amendment, alteration or repeal of any provision of the Certificate of Incorporation (including this Certificate of Designation) or the Corporation’s bylaws or the equivalent documents of another corporation that would adversely affect the rights or preferences of the Series A Preferred Stock, except that the Holders will have no right to vote under this provision if (x) the Series A Preferred Stock remains outstanding with the same rights, preferences, privileges and voting powers 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, that is an entity organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and (y) such Series A Preferred Stock remaining outstanding with the same rights, preferences, privileges and voting powers or such preference securities, as the case may be, have such rights, preferences, privileges and voting powers, taken as a whole, as are not materially less favorable to the Holders thereof than the rights, preferences, privileges and voting powers of the Series A Preferred Stock, taken as a whole; provided, that any increase in the amount of the authorized Preferred Stock of the Corporation or any securities convertible into the Preferred Stock of the Corporation or the creation and issuance, or an increase in the authorized or issued amount, of any series of Preferred Stock of the Corporation or any securities convertible into Preferred Stock of the Corporation ranking equally with and/or junior to the Series A Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and/or the distribution of assets upon the Corporation’s liquidation, dissolution or winding up will not, in and of itself, be deemed to adversely affect the rights or preference of the Series A Preferred Stock and, notwithstanding any provision of Delaware law, Holders will have no right to vote solely by reason of such an increase, creation or issuance.

(c) Notwithstanding the foregoing, Holders shall not have any voting rights if, at or prior to the effective time of the act with respect to which such vote would otherwise be required, all outstanding shares of Series A Preferred Stock shall have been converted into shares of Common Stock.

16

13. Fractional Shares.

(a) No fractional shares of Common Stock will be issued as a result of any conversion of shares of Series A Preferred Stock, except with respect to their rights as holders of Common Stock.

(b) In lieu of any fractional share of Common Stock otherwise issuable in respect of any mandatory conversion pursuant to Section 8 hereof, the Corporation shall pay an amount in cash (computed to the nearest cent) equal to the same fraction of the Current Market Price of the Common Stock determined as of the second Trading Day immediately preceding the Mandatory Conversion Date (such amount in cash, the “Fractional Share Cash Payment”); provided, that to the extent the Corporation is prevented from making such Fractional Share Cash Payments due to Cash Payment Restrictions, the Corporation shall issue a senior unsecured promissory note from the Corporation on terms reasonably satisfactory to the Holder and the Corporation for a cash amount equal to the Fractional Share Cash Payment.

(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 issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of the Series A Preferred Stock so surrendered.

14. Reservation of Common Stock.

(a) The Corporation shall at all times reserve and keep available out of its authorized and unissued Common Stock, solely for issuance upon the conversion of shares of Series A Preferred Stock as provided in this Certificate of Designation free from any preemptive or other similar rights, such number of shares of Common Stock as shall from time to time be issuable upon the conversion of all the shares of Series A Preferred Stock then outstanding.

(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, security interests and other encumbrances.

(d) The Corporation hereby covenants and agrees that, if at any time the Common Stock shall be listed on the NASDAQ Global Market or any other national securities exchange or automated quotation system, the Corporation will, 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 the Common Stock issuable upon conversion of the Series A Preferred Stock.

17

15. Replacement Certificates.

(a) The Corporation shall replace any mutilated certificate at the Holder’s expense upon surrender of that certificate to the Corporation. The Corporation shall replace certificates that become destroyed, stolen or lost at the Holder’s expense upon delivery to the Corporation of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with any indemnity that may be required by the Corporation.

(b) The Corporation shall not be required to issue any certificates representing the Series A Preferred Stock on or after the Mandatory Conversion Date. In place of the delivery of a replacement certificate following the Mandatory Conversion Date, the Corporation, upon delivery of the evidence and indemnity described in clause (a) above, shall deliver the shares of Common Stock pursuant to the terms of the Series A Preferred Stock formerly evidenced by the certificate.

16. Miscellaneous.

(a) All notices referred to herein shall be in writing, and, unless otherwise specified herein, all notices hereunder shall be deemed to have been given upon the earlier of receipt thereof or three Business Days after the mailing thereof if sent by registered or certified mail (unless first-class mail shall be specifically permitted for such notice under the terms of this Certificate of Designation) with postage prepaid, addressed: (i) if to the Corporation, to its office at 5550 SW Macadam Avenue, Suite 200, Portland, Oregon 97239, Attention: Edward T.

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 registered 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.

(c) All payments on the shares of Series A Preferred Stock shall be subject to withholding and backup withholding of tax to the extent required by applicable law, subject to applicable exemptions, and amounts withheld, if any, shall be treated as received by the holders thereof.

(d) No share of Series A Preferred Stock shall have any rights of preemption whatsoever under this Certificate of Designation 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.
