Dividends on the Series A Preferred Stock shall be calculated on the basis of a 360-day year, shall accrue daily commencing on the Original Issue Date for the applicable Series A Preferred Stock, and shall be deemed to accrue from such date whether or not earned or declared and whether or not there are profits, surplus or other funds of the Corporation legally available for the payment of dividends. Dividends payable pursuant to this Section 3(a) shall be payable by the Corporation, at its option, in cash, or by adding the amount of accrued dividends per share of Series A Preferred Stock to the Stated Value of that share.

5

to all dividends that would otherwise be payable on a share of Series A Preferred Stock on each Dividend Payment Date on and after the occurrence of such Acceleration Event and prior to and including the seventh anniversary of such Original Issue Date (the “Acceleration Period”). The automatic increase in Stated Value pursuant to this Section 3(b) shall be in lieu of, and not in addition to, the dividends that would otherwise be payable on each Dividend Payment Date during the Acceleration Period. For the purpose of clarity, and only in the event that the Corporation has not elected to require conversion under Section 7(b), each Holder shall be entitled to receive, and the Corporation shall pay, all dividends payable in accordance with Section 3(a) above on each Dividend Payment Date after the seventh anniversary of the Original Issue Date.

(c) Notwithstanding anything in this Certificate of Designation to the contrary, an amount equal to the sum of all accrued but unpaid dividends shall be payable upon,

(i) a Liquidation Event in cash;

(ii) a Fundamental Transaction that the Holders elect to treat as a Liquidation Event pursuant to Section 6(c) in cash or in other securities or property as specified in Section 6(c); or

5. Registration of Transfers. Subject to the terms of the Stockholder’s Agreement, the Corporation shall register the transfer of any shares of Series A Preferred Stock in the Series A Preferred Stock Register, upon surrender of certificates evidencing such Shares to the Corporation at its address specified herein. Upon any such registration or transfer, a new certificate evidencing the shares of Series A Preferred Stock so transferred shall be issued to the transferee and a new certificate evidencing the remaining portion of the shares not so transferred, if any, shall be issued to the transferring Holder.

6. Liquidation.

(a) In the event of any Liquidation Event, the Holders of Series A Preferred Stock shall be entitled to receive, prior and in preference to any distribution of any of the assets or surplus funds of the Corporation to the holders of Junior Securities by reason of their ownership thereof, an amount per share in cash equal to the greater of (i) the Stated Value for each share of Series A Preferred Stock then held by them (as adjusted for any stock split, stock dividend, stock combination or other similar transactions with respect to the Series A Preferred Stock), plus all accrued but unpaid dividends (including, without duplication, dividends added to Stated Value as provided in Section 3 above) on such Series A Preferred Stock as of the date of such event, and (ii) the amount per share that would be payable to a holder of Series A Preferred Stock had all shares of Series A Preferred Stock been converted to Underlying Shares immediately prior to such Liquidation Event (the “Series A Stock Liquidation Preference”). If, upon the occurrence of a Liquidation Event, the assets and funds thus distributed among the holders of the Series A Preferred Stock shall be insufficient to permit the payment to such Holders of the full Series A Stock Liquidation Preference, then the entire assets and funds of the Corporation legally available for distribution shall be distributed ratably among the Holders of the Series A Preferred Stock in proportion to the aggregate Series A Stock Liquidation Preference that would otherwise be payable to each of such Holders.

(b) In the event of a Liquidation Event, following completion of the distributions required by the first sentence of paragraph (a) of this Section 6, if assets or surplus funds remain in the Corporation, the holders of the Common Stock and other Junior Securities shall share in all remaining assets of the Corporation.

(c) The Corporation shall provide written notice of any Liquidation Event or Fundamental Transaction to each record Holder not less than 45 days prior to the payment date or effective date thereof. At the request of any Holder, which must be delivered prior to the effective date of a Fundamental Transaction (or, if later, within five (5) Trading Days after such Holder receives notice of such Fundamental Transaction from the Corporation), such Fundamental Transaction will be treated as a Liquidation Event with respect to such Holder for the purposes of this Section 6; provided, however, that if the consideration to be paid to the holders of the Common Stock is not to be paid in cash, but rather in securities or other property, then at the option of the Corporation, the amount payable to the Holders pursuant to this Section 6(c) shall be either (i) in cash or (ii) in the same securities or other property as is to be paid to the holders of Common Stock so long as (a) such securities or other property consist exclusively of common equity interests quoted on the Nasdaq Stock Market or listed on the New York Stock Exchange or on the American Stock Exchange, (b) the value of such common equity interests shall be determined as 98% of the closing price of such common equity interests on the Nasdaq Stock Market, the New York Stock Exchange or the American Stock Exchange, as the case may be, on the Trading Day immediately preceding the consummation of such Fundamental Transaction and (c) such common equity interests shall be freely transferable by the Holders, without legal or contractual restrictions. At the request of the Original Purchaser, prior to the issuance of any common equity interests referred to in the preceding sentence, counsel to the issuer of such common equity interests familiar with United States federal securities laws shall provide the Purchaser with a legal opinion to the effect that such common equity interests are transferable without legal restriction under United States federal securities laws.

7

(d) In the event that, immediately prior to the closing of a Liquidation Event the cash distributions required by subsection 6(a) have not been made, the Corporation shall forthwith either: (i) cause such closing to be postponed until such time as such cash distributions have been made, or (ii) cancel such transaction, in which event the rights, preferences and privileges of the holders of the Series A Preferred Stock shall revert to and be the same as such rights, preferences and privileges existing immediately prior to the date of the first notice by the Corporation required under subsection 6(c).

7. Conversion; Redemption

(a) Conversion at Option of Holder. At the option of any Holder, any shares of Series A Preferred Stock may be converted into Common Stock based on the Conversion Price then in effect for the Series A Preferred Stock; provided that if less than 20% of the number of shares of Series A Preferred Stock outstanding on the date the Series A Preferred Stock is first issued by the Corporation would remain outstanding after any such conversion, then all shares must be converted at that time. A Holder may convert shares of Series A Preferred Stock into Common Stock pursuant to this paragraph at any time and from time to time after the Original Issue Date, by delivering to the Corporation a conversion notice (the “Holder Conversion Notice”), in the form attached hereto as Exhibit A, appropriately completed and duly signed, and the date any such Holder Conversion Notice is delivered to the Corporation (as determined in accordance with the notice provisions hereof) is a “Conversion Date.”

(b) Conversion at Option of Corporation. At any time that (i) the average Closing Price for at least 20 Trading Days within a period of 30 consecutive Trading Days ending on the Trading Day prior to the date of the Corporation Conversion Notice (as defined below) exceeds 150% of the Conversion Price or (ii) a Fundamental Transaction occurs that the Holders do not elect to treat as a Liquidation Event, the Corporation may elect to require the Holders to convert all shares of the Series A Preferred Stock into Common Stock based on the Conversion Price by delivering an irrevocable written notice of such election to the Holders (the “Corporation Conversion Notice”). The tenth (10^th) Trading Day after the delivery of such notice will be the “Conversion Date” for such required conversion. Notwithstanding the foregoing, (x) in the event of a conversion at the option of the Corporation predicated on clause (i) of the first sentence of this Section 7(b), the Corporation may not require any conversion under this paragraph (and any notice thereof will be void), prior to the second anniversary of the Original Issue Date and unless from the beginning of such ten Trading Day period through the Conversion Date, the Closing Price for each such Trading Day exceeds 150% of the Conversion Price, and (y) in the event of a conversion at the option of the Corporation predicated on clause (i) or (ii) of the first sentence of this Section 7(b), the Corporation may not require any conversion under this paragraph (and any notice thereof will be void), unless the Equity Conditions are satisfied (or waived in writing by the applicable Holder) on each Trading Day between the date of the Conversion Notice and the Conversion Date with respect to all of the Underlying Shares then issuable upon conversion in full of all outstanding Series A Preferred Stock.

(c) Redemption at Option of Holder. On or after the seventh anniversary of the Original Issue Date, the Holder may, at its option, require the Corporation to redeem any of the Series A Preferred Stock owned by the Holder, for an amount per share in cash equal to the

8

Stated Value on the Redemption Date plus all accrued and unpaid dividends that have not been added to Stated Value on the Redemption Date (the “Cash Redemption Price”) for each share of Series A Preferred Stock (as adjusted for any stock split, stock dividend, stock combination or other similar transactions with respect to the Series A Preferred Stock) to be redeemed on the Redemption Date (as defined below) . Additionally, if the product of (X) the average Closing Price of the ten (10) Trading Days immediately preceding the Redemption Date (the “Company Redemption Closing Price”) and (Y) the number of shares of Common Stock that would have been issued had the Holder converted all outstanding shares of Series A Preferred Stock being redeemed into shares of Common Stock on the Redemption Date (such product being referred to as the “Common Stock As Converted Cash Value”) exceeds the aggregate Cash Redemption Price, the Holder will receive on the Redemption Date, in addition to the aggregate Cash Redemption Price, in shares of Common Stock, the amount by which the Common Stock As Converted Cash Value exceeds the aggregate Cash Redemption Price, with the per share value for the Common Stock so issued and delivered being the Company Redemption Closing Price. The redemption date (the “Redemption Date”) shall be specified in an irrevocable written notice of redemption sent by or on behalf of the Holder (pursuant to this Section 7(c)) or Corporation (pursuant to Section 7(d)), as the case may be, to the Holder or the Corporation, as applicable, not less than thirty (30) days nor more than ninety (90) days prior to the proposed Redemption Date notifying the Corporation or the Holder, as applicable, of the election of the Corporation or the Holder, as the case may be, to redeem such shares in accordance with the terms hereof and specifying the Redemption Date.

(d) Redemption at Option of Corporation. On or after the seventh anniversary of the Original Issue Date, the Corporation may, at its option, redeem any of the Series A Preferred Stock owned by the Holders, for the Cash Redemption Price plus, if the Common Stock As Converted Cash Value exceeds the aggregate Cash Redemption Price, the Holder will receive on the Redemption Date, in addition to the aggregate Cash Redemption Price, in shares of Common Stock, the amount by which the Common Stock As Converted Cash Value exceeds the Cash Redemption Price, with the per share value for the Common Stock so issued and delivered being the Company Redemption Closing Price; provided that if less than 20% of the number of shares of Preferred Stock outstanding on the date the Preferred Stock is first issued by the Corporation would remain outstanding after any such redemption, then all shares must be redeemed at that time.

8. Mechanics of Conversion; Redemption.

(a) The Corporation shall pay the applicable Cash Redemption Price in immediately available funds to the Holder on the Redemption Date.

(b) The number of Underlying Shares issuable upon any conversion of shares of Series A Preferred Stock hereunder shall equal (A) the sum of (i) the Stated Value of such shares of Series A Preferred Stock to be converted plus (ii) the accrued and unpaid dividends on such shares of Series A Preferred Stock that have not been added to the Stated Value on the Conversion Date, divided by (B) the applicable Conversion Price on the Conversion Date.

(c) Upon conversion or redemption (if the Common Stock as Converted Cash Value exceeds the aggregate Cash Redemption Price) of any shares of Series A Preferred Stock,

9

the Corporation shall promptly issue or cause to be issued and cause to be delivered to or upon the written order of the Holder and in such name or names as the Holder may designate a certificate for the Underlying Shares issuable upon such conversion or redemption, free of restrictive legends unless such Underlying Shares are still required to bear a restrictive legend; the Corporation shall use its commercially reasonable efforts to cause the transfer agent to issue such certificates on or before (i) the sixth Trading Day after the Conversion Date or (ii) the Redemption Date, as the case may be. The Holder shall be deemed to have become holder of record of such Underlying Shares as of the Conversion Date or Redemption Date as the case may be. If the shares are then not required to bear a restrictive legend, the Corporation shall, upon request of the Holder, deliver Underlying Shares hereunder electronically through The Depository Trust Corporation (“DTC”) or another established clearing corporation performing similar functions, and shall credit the number of shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission System (“DWAC”).

(d) A Holder shall deliver the original certificate(s) evidencing the Series A Preferred Stock being converted or redeemed in connection with the conversion or redemption of such Series A Preferred Stock. Upon surrender of a certificate following one or more partial conversions or redemptions, the Corporation shall promptly deliver to the Holder a new certificate representing the remaining shares of Series A Preferred Stock.

(e) The Corporation’s obligations to issue and deliver Underlying Shares upon conversion of Series A Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by any Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by any Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by any Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to any Holder in connection with the issuance of such Underlying Shares.

9. Voting Rights; Director Designation.

(a) Except as otherwise provided in this Section 9(a) or in Section 9(b) or as required by applicable law, the Holders of the Series A Preferred Stock shall be entitled to vote on all matters on which holders of Common Stock are entitled to vote. For such purposes, each Holder shall be entitled to a number of votes in respect of the shares of Series A Preferred Stock owned of record by it equal to the number of shares of Common Stock into which such shares of Series A Preferred Stock are convertible by the Holders as of the record date for the determination of stockholders entitled to vote on such matter, or if no record date is established, at the date such vote is taken or any written consent of stockholders is solicited. Except as otherwise provided in this Section 9(a) or in Section 9(b), in any relevant agreement or as required by applicable law, the holders of the Series A Preferred Stock and Common Stock shall vote together as a single class on all matters submitted to a vote or consent of stockholders; provided that so long as any shares of Series A Preferred Stock are outstanding, the Corporation shall not, without the affirmative vote of the Holders of a majority of the shares of Series A Preferred Stock then outstanding, voting together as a separate class,

(ii) authorize or create any class or series of stock ranking as to dividends, redemption or distribution of assets upon a Liquidation Event or Fundamental Transaction senior to or otherwise pari passu with the Series A Preferred Stock, including without limitation through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action) or avoid or seek to avoid the observance or performance of any or the terms to be observed or performed hereunder by the Corporation;;

(iii) increase the authorized number of shares of Series A Preferred Stock;

(iv) pay or declare any dividend or make any distribution on, or redeem or acquire, any Junior Securities, except pro rata stock dividends on the Common Stock payable in additional shares of Common Stock; or

(vi) enter into any agreement with respect to the foregoing.

The protective rights set forth above in (iv) will terminate and cease to apply on the earliest to occur of (A) the first date on which there are outstanding less than 30% of the number of shares of Series A Preferred Stock that were outstanding on the date the Series A Preferred Stock is first issued by the Corporation and (B) the first date on which the outstanding shares of Series A Preferred Stock represent, in the aggregate, less than 20% of the Post-Conversion Equity. The protective rights set forth above in (v) will terminate and cease to apply on the date that both (A) and (B) have occurred.

(b) The Original Purchaser shall not be entitled nor have the right or power to vote in any election or removal, with or without cause, of directors of the Corporation elected or removed generally by the holders of the Common Stock (and any capital stock entitled to vote in the election or removal of directors with the holders of the Common Stock) except as set forth in clause (iv) below but shall instead have the special voting rights set forth in this Section 9(b). At

11

each election of directors, the Original Purchaser shall be entitled to elect such number of directors to the Corporation’s board of directors equal to the product of (x) a fraction, the numerator of which is the number of shares of Common Stock into which the shares of Series A Preferred Stock then owned by the Original Purchaser and its Affiliates are convertible, and the denominator of which is the total number of shares of Common Stock then outstanding (assuming the conversion of all then outstanding shares of Series A Preferred Stock), in each case, calculated as of the record date for the election of such director(s), or if no record date is established, the date on which such vote is taken or any written consent of stockholders relating thereto is solicited and (y) the total number of directors as established in accordance with the Bylaws of the Corporation. Such product shall be rounded down to the nearest whole number; provided, that if the fraction calculated pursuant to (x) above is greater than  ¹/2, such product shall be rounded up to the nearest whole number if rounding down to the nearest whole number would result in the Original Purchaser having the right to elect less than a majority of the directors to the board of directors. Notwithstanding the foregoing, the Original Purchaser shall at all times have the right to elect the minimum number of directors set forth in each of clauses (i), (ii) and (iii) below so long as the ownership requirements set forth in such clauses is satisfied.

Common Stock representing on an as converted or exercised basis more than 10% of the Post-Conversion Equity of the Corporation, then the Original Purchaser shall not be entitled to elect any directors to the Corporation’s board of directors pursuant to this Section 9(b) but shall have the right and power to vote in any election or removal, with or without cause, of directors of the Corporation elected or removed generally by the holders of the Common Stock (and any capital stock entitled to vote in the election or removal of directors with the holders of the Common Stock) pursuant to Section 9(a).

The Original Purchaser may remove any director elected pursuant to this Section 9(b) at any time and from time to time, without cause (subject to the Bylaws of the Corporation and any requirements of law), in its sole discretion. In the event a director elected by the Original Purchaser is removed, the vacancy in the board of directors shall be filled by the Original Purchaser, and such action shall be taken only by vote or written consent in lieu of a meeting of the holders of the Series A Preferred Stock or by any remaining director or directors elected by the holders of Series A Preferred Stock pursuant to this Section 9(b).

10. Charges, Taxes and Expenses. Issuance of certificates for shares of Series A Preferred Stock and for Underlying Shares issued on conversion of (or otherwise in respect of) the Series A Preferred Stock shall be made without charge to the Holders for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Corporation. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring the Series A Preferred Stock or receiving Underlying Shares in respect of the Series A Preferred Stock.

11. Replacement Certificates. If any certificate evidencing Series A Preferred Stock or Underlying Shares is mutilated, lost, stolen or destroyed, or a Holder fails to deliver such certificate as may otherwise be provided herein, the Corporation shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution for such certificate, a new certificate, but only upon receipt of evidence reasonably satisfactory to the Corporation of such loss, theft or destruction (in such case) and, in each case, customary and reasonable indemnity, if requested. Applicants for a new certificate under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Corporation may prescribe.

12. Reservation of Underlying Shares. The Corporation covenants that it shall at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Underlying Shares as required hereunder, the number of Underlying Shares which are then issuable and deliverable upon the conversion of (and otherwise in respect of) all outstanding Series A Preferred Stock (taking into account the adjustments of Section 13), free from preemptive rights or any other contingent purchase rights of persons other than the Holder. The Corporation covenants that all Underlying Shares so issuable and deliverable shall, upon issuance in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and

13

nonassessable. The Corporation covenants that it shall use its best efforts to satisfy each of the Equity Conditions.

13. Certain Adjustments. The Conversion Price is subject to adjustment from time to time as set forth in this Section 13. Such adjustments shall be made to the Conversion Price for all shares of Series A Preferred Stock from and after the Original Issue Date.

(a) Stock Dividends and Splits. If the Corporation, at any time while Series A Preferred Stock is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the applicable Conversion Price for Series A Preferred Stock shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

(b) Pro Rata Distributions. If the Corporation, at any time while Series A Preferred Stock is outstanding, distributes or pays as a dividend to holders of Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (including, without limitation, cash) (in each case, “Distributed Property”), then in each such case the Corporation shall simultaneously deliver to each Holder the Distributed Property that each such Holder would have been entitled to receive in respect of the number of Underlying Shares then issuable pursuant to Section 7(a) above had the Holder been the record holder of such Underlying Shares immediately prior to the applicable record or payment date.

(c) Fundamental Transactions. If the Corporation, at any time while Series A Preferred Stock is outstanding, effects any Fundamental Transaction, then upon any subsequent conversion of Series A Preferred Stock, each Holder shall have the right to receive, for each Underlying Share that would have been issuable upon such conversion absent such Fundamental Transaction, the same kind and amount of securities, cash or property as it could have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the “Alternate Consideration”). For purposes of any such conversion, the determination of the applicable Conversion Price for the Series A Preferred Stock shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Corporation shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then each Holder shall be given the same choice as to the

14

Alternate Consideration it receives upon any conversion of Series A Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction shall issue to the Holder a new series of preferred stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that the Series A Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(d) Calculations. All calculations under this Section 13 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Corporation, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

(e) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 13, the Corporation at its expense will promptly compute such adjustment in accordance with the terms hereof and prepare a certificate describing in reasonable detail such adjustment and the transactions giving rise thereto, including all facts upon which such adjustment is based. Upon written request, the Corporation will promptly deliver a copy of each such certificate to each Holder and to the Corporation’s Transfer Agent.

(f) Notice of Corporate Events. If the Corporation (i) declares a dividend (other than a dividend pursuant to Section 3 above) or any other distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock of the Corporation or any Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Corporation, then the Corporation shall deliver to each Holder a notice describing the material terms and conditions of such transaction, at least 20 calendar days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction.

14. Fractional Shares. The Corporation shall not be required to issue or cause to be issued fractional Underlying Shares on conversion of Series A Preferred Stock.

15. Notices. Any and all notices or other communications or deliveries hereunder (including without limitation any Conversion Notice) shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section prior to 4:30 p.m. (New York City time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in this Section on a day that is not a Trading Day or later than 4:30 p.m. (New York City time) on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom

15

such notice is required to be given. The addresses for such communications shall be: (i) if to the Corporation, to 125 High Street, 30^th Floor, Boston, MA 02110, Attention: Corporate Secretary, or (ii) if to a Holder, to the address or facsimile number appearing on the Corporation’s stockholder records or such other address or facsimile number as such Holder may provide to the Corporation in accordance with this Section.

16. Miscellaneous.

(a) The headings herein are for convenience only, do not constitute a part of this Certificate of Designations and shall not be deemed to limit or affect any of the provisions hereof.

(b) Any of the rights of the Holders of Series A Preferred Stock set forth herein, including any Equity Conditions or any other similar conditions for the Holders’ benefit, may be waived by the affirmative vote of Holders of at least a majority of the shares of Series A Preferred Stock then outstanding. No waiver of any default with respect to any provision, condition or requirement of this Certificate of Designations shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.

IN WITNESS WHEREOF, Stream Global Services, Inc. has caused this Certificate of Designations to be duly executed as of this [            ] day of [            ], 2008.
