6. VOTING RIGHTS.

(a) Election of Directors. For so long as the outstanding shares of Series B Preferred Stock, on an as-converted basis, represent the percentage (the “Series B Preferred Stock Percentage”) of the outstanding shares of Common Stock set forth below, after giving effect to the conversion into Common Stock of all outstanding shares of Series B Preferred Stock, the holders of record of the shares of Series B Preferred Stock, exclusively and as a separate class, shall be entitled to elect the number of directors of the Corporation (the “Series B Directors”) opposite such percentage.

-4-

In the event that the size of the board of directors is increased in accordance with Section 6(b)(iii) below, the Corporation and the holders of record of the shares of Series B Preferred Stock shall adjust the Series B Preferred Stock Percentages and the corresponding number of Series B Directors as such parties shall determine to be appropriate. Any director elected as provided in the preceding sentence may be removed without cause by, and only by, the affirmative vote of the holders of record of the shares of Series B Preferred Stock, exclusively and as a separate class, given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written consent of stockholders. If the holders of shares of Series B Preferred Stock fail to elect a sufficient number of directors to fill all directorships for which they are entitled to elect directors, voting exclusively and as a separate class, pursuant to the first sentence of this Section 6(a), then any directorship not so filled shall remain vacant until such time as the holders of the Series B Preferred Stock elect a person to fill such directorship by vote or written consent in lieu of a meeting; and no such directorship may be filled by stockholders of the Corporation other than by the holders of record of the shares of Series B Preferred Stock, voting exclusively and as a separate class.

At any meeting held for the purpose of electing a director, the presence in person or by proxy of the holders of a majority of the outstanding shares of the class or series entitled to elect such director shall constitute a quorum for the purpose of electing such director. Except as otherwise provided in this Section 6(a), a vacancy in any directorship filled by the holders of any class or series shall be filled only by vote or written consent in lieu of a meeting of the holders of such class or series or by any remaining director or directors elected by the holders of such class or series pursuant to this Section 6(a).

(b) Protective Provisions. Except as otherwise provided herein or as required by applicable law, the holders of Series B Preferred Stock shall be entitled to vote on all matters on which the holders of Common Stock shall be entitled to vote, in the same manner and with the same effect as the holders of Common Stock, voting together with the holders of Common Stock as a single class. For purposes of this Section 6, the holders of Series B Preferred Stock shall be given notice of any meeting of stockholders as to which the holders of Common Stock are given notice in accordance with the by-laws of the Corporation. As to any matter on which the holders of Series B Preferred Stock shall be entitled to vote in accordance with the first sentence of this Section 6(b), each holder of Series B Preferred Stock shall have a number of votes per share of Series B Preferred Stock held of record by such holder on the record date for the meeting of stockholders, if such matter is subject to a vote at a meeting of stockholders, or on the effective date of any written consent, if such matter is subject to a written consent of the stockholders without a meeting of stockholders, equal to the number of shares of Common Stock into which such share of Series B Preferred Stock is then convertible on such record date or effective date, as the case may be, in accordance with Section 7 hereof but without regard to the limitations on conversion set forth in the third sentence of Section 7(b)(iii) below.

The date of such conversion (the “Conversion Date”) shall be the date that such holder delivers written notice to the transfer agent for the Series B Preferred Stock (or at the principal offices of the Corporation if the Corporation serves as its own transfer agent), that such holder elects to convert such number of shares as is set forth in such notice. The “Series B Conversion Price” shall initially be Thirteen Cents ($0.13), and shall be subject to adjustment as described in Section 7(c) hereof.

(b) Mechanics of Conversion.

(i) On the Conversion Date: (A) the Person in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon conversion shall be deemed to have become the holder of record of the shares of Common Stock represented thereby at such time, and (B) the shares of Series B Preferred Stock so converted shall no longer be deemed to be outstanding, and all rights of a holder with respect to such shares shall immediately terminate except the right to receive the Common Stock and other amounts payable pursuant to this Section 7. All shares of Common Stock delivered upon conversion of the Series B Preferred Stock will, upon delivery, be duly and validly authorized and issued, fully paid and nonassessable, free from all preemptive rights and free from all taxes, liens, security interests and charges (other than liens or charges created by or imposed upon the holder or taxes in respect of any transfer occurring contemporaneously therewith).

(ii) Holders of shares of Series B Preferred Stock at the close of business on the record date for any payment of a dividend in which shares of Series B Preferred Stock are to participate pursuant to Section 4 hereof shall be entitled to receive the dividend payable on such shares on the corresponding dividend payment date notwithstanding the conversion thereof following such dividend payment record date and prior to such dividend payment date, and a holder of shares of Series B Preferred Stock on a dividend payment record date whose shares of Series B Preferred Stock have been converted pursuant to Section 7(a) into shares of Common Stock on such dividend payment date will receive the dividend payable by the Corporation on such shares of Series B Preferred Stock if and when paid, and the converting holder need not include payment of the amount of such dividend upon conversion of shares of Series B Preferred Stock pursuant to Section 7(a).

(iii) From the date of this Certificate and until the filing of the Common Stock Authorization Amendment with the Secretary of State of the State of Delaware in accordance with the Investment Agreement, the Corporation will at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of effecting conversions of the Series B Preferred Stock, Nineteen Million Three Hundred Seventy Seven Thousand Eighty Six (19,377,086) of its authorized but unissued shares of Common Stock (as appropriately adjusted for any stock dividend, stock split, reverse stock split, reclassification, stock combination or other recapitalization occurring after the date hereof). From and after the filing of the Common Stock Authorization Amendment with the Secretary of State of the State of Delaware in accordance with the Investment Agreement, the Corporation will at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of effecting conversions of the Series B Preferred Stock, the aggregate number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock (as if all shares of Series B Preferred Stock are so convertible). From the date of this Certificate and until

-8-

the filing of the Common Stock Authorization Amendment with the Secretary of State of the State of Delaware in accordance with the Investment Agreement, the holder of any share or shares of Series B Preferred Stock shall be entitled to convert, in the aggregate, only such number of shares of Series B Preferred Stock as shall be convertible into Nineteen Million Three Hundred Seventy Seven Thousand Eighty Six (19,377,086) of its authorized but unissued shares of Common Stock (as appropriately adjusted for any stock dividend, stock split, reverse stock split, reclassification, stock combination or other recapitalization occurring after the date hereof). The foregoing limitation shall not apply from and after the filing of the Common Stock Authorization Amendment with the Secretary of State of the State of Delaware in accordance with the Investment Agreement. The Corporation will procure, at its sole expense, the listing of all shares of Common Stock issuable upon conversion of Series B Preferred Stock, subject to issuance or notice of issuance, on the principal domestic stock exchange on which the Common Stock is then listed or traded. The Corporation will take all action as may be necessary to ensure that all shares of Common Stock issuable upon conversion of Series B Preferred Stock will be issued without violation of any applicable law or regulation or of any requirement of any securities exchange on which the shares of Common Stock are listed or traded.

(iv) Issuances of certificates for shares of Common Stock upon conversion of the Series B Preferred Stock shall be made without charge to the holder of shares of Series B Preferred Stock or any of its transferees for any issue or transfer tax or other incidental expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Corporation.

(v) In connection with the conversion of any shares of Series B Preferred Stock, no fractions of shares of Common Stock shall be issued, but in lieu thereof the Corporation shall pay cash in respect of such fractional interest in an amount equal to such fractional interest multiplied by the Fair Market Value per share of Common Stock on the applicable Conversion Date.

(vi) The Corporation shall procure that each share of Common Stock issued as a result of conversion of Series B Preferred Stock shall be accompanied by any rights associated generally with each other share of Common Stock outstanding as of the applicable Conversion Date.

(c) Adjustments to Conversion Price. From and after the date of this Certificate, the Conversion Price shall be adjusted from time to time as follows:

(i) Common Stock Event. Upon the occurrence of a Common Stock Event, the Conversion Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted to the number obtained by multiplying the Conversion Price theretofore in effect by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such action, and the denominator of which shall be the number of shares of Common Stock outstanding immediately following such action.

(ii) Adjustments for Other Dividends and Distributions. If at any time or from time to time after the date of the original issuance of shares of Series B Preferred Stock, the Corporation pays a dividend or makes another distribution to the holders of the Common Stock

-9-

payable in securities of the Corporation, other than an event constituting a Common Stock Event then, in each such event, provision shall be made so that the holders of the Series B Preferred Stock shall receive upon conversion thereof, in addition to the number of shares of Common Stock receivable upon conversion thereof, the amount of securities of the Corporation which they would have received had their Series B Preferred Stock been converted into Common Stock on the date of such event (or such record date, as applicable) and had they thereafter, during the period from the date of such event (or such record date, as applicable) to and including the conversion date, retained such securities receivable by them as aforesaid during such period, subject to all other adjustments called for during such period under this Section 7 with respect to the rights of the holders of the Series B Preferred Stock or with respect to such other securities by their terms.

(iii) Adjustment for Reclassification, Exchange and Substitution. If at any time or from time to time after the date of the original issuance of shares of Series B Preferred Stock, the Common Stock issuable upon the conversion of the Series B Preferred Stock is changed into the same or a different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise (other than by a Common Stock Event or a Business Combination covered by Sections 7(c)(i) or 7(c)(iv) hereof), then in any such event each holder of Series B Preferred Stock shall have the right thereafter to receive the kind and amount of stock and other securities and property receivable upon such recapitalization, reclassification or other change by holders of the number of shares of Common Stock into which such shares of Series B Preferred Stock could have been converted (but without regard to the limitations on conversion set forth in the third sentence of Section 7(b)(iii) above) immediately prior to such recapitalization, reclassification or change, all subject to further adjustment as provided herein or with respect to such other securities or property by the terms thereof.

(iv) Business Combinations. In case of any Business Combination or reclassification of Common Stock (other than a reclassification of Common Stock covered by Section 7(c)(iii) hereof), lawful provision shall be made as part of the terms of such Business Combination or reclassification whereby the holder of each share of Series B Preferred Stock then outstanding shall have the right to convert into the kind and amount of securities, cash and other property receivable upon the Business Combination or reclassification by a holder of the number of shares of Common Stock of the Corporation into which a share of Series B Preferred Stock would have been convertible at the conversion rate described under this Section 7 immediately prior to the Business Combination or reclassification (but without regard to the limitations on conversion set forth in the third sentence of Section 7(b)(iii) above).

(d) Anti-Dilution Protection.

(i) No Adjustment of Conversion Price. No adjustment in the number of shares of Common Stock into which the shares of any Series B Preferred Stock is convertible shall be made with respect to such series, by adjustment in the applicable Conversion Price thereof, or by reason of issuance or deemed issuance of Additional Shares of Common Stock (as defined in Section 7(d)(iii)(A)): (A) unless the Effective Price of such Additional Shares (determined pursuant to Section 7(d)(iii)(E)) is less than the applicable Conversion Price in effect on the date of, and immediately prior to, the issue of such Additional Shares of Common Stock, or (B) if, prior to such issuance, the Corporation receives written consent from the holders of at least a majority of the then outstanding shares of such series agreeing that no such adjustment shall be made as the result of the issuance of Additional Shares of Common Stock.

(ii) Adjustment Formula. If at any time or from time to time after the date of the original issuance of shares of Series B Preferred Stock, the Corporation issues or sells, or is deemed by the provisions of this Section 7(d) to have issued or sold, Additional Shares of Common Stock, other than a Common Stock Event as provided in Section 7(c)(i), a dividend or distribution as provided in Section 7(c)(ii), a recapitalization, reclassification or other change as provided in Section 7(c)(iii), or a reorganization, merger or consolidation as provided in Section 7(c)(iv), for an Effective Price that is less than the Conversion Price in effect immediately prior to such issue or sale (or deemed issue or sale), then, and in each such case, the Conversion Price shall be reduced, as of the close of business on the date of such issue or sale to the price obtained by multiplying such Conversion Price by a fraction:

(A) The numerator of which shall be the sum of (1) the number of Common Stock Equivalents Outstanding (as defined in Section 7(d)(iii)(C)) immediately prior to such issue or sale of Additional Shares of Common Stock plus (2) the quotient obtained by dividing: (x) the Aggregate Consideration Received (as defined in Section 7(d)(iii)(B)) by the Corporation for the total number of Additional Shares of Common Stock so issued or sold (or deemed so issued and sold) by (y) the Conversion Price in effect immediately prior to such issue or sale; and

(B) The denominator of which shall be the sum of (1) the number of Common Stock Equivalents Outstanding immediately prior to such issue or sale plus (2) the number of Additional Shares of Common Stock so issued or sold (or deemed so issued and sold).

(iii) Certain Definitions. For the purpose of making any adjustment required under this Section 7(d):

(A) “Additional Shares of Common Stock” shall mean all shares of Common Stock issued by the Corporation, whether or not subsequently reacquired or retired by the Corporation, other than:

(1) shares of Common Stock issued or issuable upon conversion of the outstanding shares of the Series B Preferred Stock or as a dividend or distribution on the Series B Preferred Stock;

(2) any shares of Common Stock, or Rights or Options (as defined in clause (F) granted or issued hereafter to employees, officers or directors of, or contractors, consultants or advisers to, the Corporation or any Subsidiary pursuant to incentive agreements, stock purchase or stock option plans, stock bonuses or awards, warrants, contracts or other arrangements that are approved by the Board;

(3) any shares of the Corporation’s Common Stock or Preferred Stock, or Rights or Options issued, or issuable to parties that are (i) strategic partners investing in connection with a commercial relationship with the Corporation or (ii) providing the Corporation with equipment leases, real property leases, loans, credit lines, guaranties of indebtedness, cash price reductions or similar transactions, under arrangements, in each case, approved by the Board;

-11-

(4) shares of Common Stock or Preferred Stock issued pursuant to the acquisition of another corporation or entity by the Corporation by consolidation, merger, purchase of all or substantially all of the assets, or other reorganization in which the Corporation acquires, in a single transaction or series of related transactions, all or substantially all of the assets of such other corporation or entity or fifty percent (50%) or more of the voting power of such other corporation or entity or fifty percent (50%) or more of the equity ownership of such other entity;

(5) shares of Common Stock or Preferred Stock issuable upon exercise of any options, warrants or rights to purchase any securities of the Corporation outstanding as of the date of filing of this Certificate of Designations, Preferences and Rights and any securities issuable upon the conversion thereof;

(6) any shares of Common Stock or Preferred Stock, or Rights or Options, issued or issuable hereafter that are (i) approved by the Board, and (ii) approved by the vote or written consent of the holders of a majority of the Series B Preferred Stock, as being excluded from the definition of “Additional Shares of Common Stock” under this Section 7(d)(iii)(A).

(B) The “Aggregate Consideration Received” by the Corporation for any issue or sale, or deemed issue or sale, of securities shall (1) to the extent it consists of cash, be computed at the gross amount of cash received by the Corporation before deduction of any underwriting or similar commissions, compensation or concessions paid or allowed by the Corporation in connection with such issue or sale and without deduction of any expenses payable by the Corporation; (2) to the extent it consists of property other than cash, be computed at the fair value of that property as determined in good faith by the Board; and (3) if Additional Shares of Common Stock, Convertible Securities or Rights or Options to purchase either Additional Shares of Common Stock or Convertible Securities are issued or sold together with other stock or securities or other assets of the Corporation for a consideration which covers both, be computed as the portion of the consideration so received that may be reasonably determined in good faith by the Board to be allocable to such Additional Shares of Common Stock, Convertible Securities or Rights or Options.

(C) The “Common Stock Equivalents Outstanding” shall mean the number of shares of Common Stock that is equal to the sum of (1) all shares of Common Stock of the Corporation that are issued and outstanding at the time in question, plus (2) all shares of Common Stock of the Corporation issuable upon conversion of all shares of Preferred Stock or other Convertible Securities that are issued and outstanding and may be converted at the time in question, plus (3) all shares of Common Stock of the Corporation that are issuable upon the exercise of Rights or Options that are outstanding and may be exercised at the time in question assuming the full conversion or exchange into Common Stock of all such Rights or Options that are Rights or Options to purchase or acquire Convertible Securities.

(D) The “Convertible Securities” shall mean stock or other securities convertible into or exchangeable for shares of Common Stock.

(E) The “Effective Price” of Additional Shares of Common Stock shall mean the quotient determined by dividing the total number of Additional Shares of Common Stock issued or sold, or deemed to have been issued or sold under this Section 7(d), by

-12-

the Corporation into the Aggregate Consideration Received, or deemed to have been received, by the Corporation under this Section 7(d), for the issue of such Additional Shares of Common Stock; and

(F) The “Rights or Options” shall mean warrants, options or other rights to purchase or acquire shares of Common Stock or Convertible Securities.

(iv) Deemed Issuances. For the purpose of making any adjustment to the Conversion Price of Series B Preferred Stock required under this Section 7(d), if the Corporation issues or sells any Rights or Options or Convertible Securities and if the Effective Price of the shares of Common Stock issuable upon exercise of such Rights or Options or the conversion or exchange of Convertible Securities (computed without reference to any additional or similar protective or antidilution clauses) is less than the Conversion Price then in effect for Series B Preferred Stock, then the Corporation shall be deemed to have issued, at the time of the issuance of such Rights, Options or Convertible Securities, that number of Additional Shares of Common Stock that is equal to the maximum number of shares of Common Stock issuable upon exercise or conversion of such Rights, Options or Convertible Securities upon their issuance and to have received, as the Aggregate Consideration Received for the issuance of such shares, an amount equal to the total amount of the consideration, if any, received by the Corporation for the issuance of such Rights or Options or Convertible Securities, plus, in the case of such Rights or Options, the minimum amounts of consideration, if any, payable to the Corporation upon the exercise in full of such Rights or Options, plus, in the case of Convertible Securities, the minimum amounts of consideration, if any, payable to the Corporation (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) upon the conversion or exchange thereof; provided that:

(A) if the minimum amounts of such consideration cannot be ascertained, but are a function of antidilution or similar protective clauses, then the Corporation shall be deemed to have received the minimum amounts of consideration without reference to such clauses;

(B) if the minimum amount of consideration payable to the Corporation upon the exercise of Rights or Options or the conversion or exchange of Convertible Securities is reduced over time or upon the occurrence or non-occurrence of specified events other than by reason of antidilution or similar protective adjustments, then the Effective Price shall be recalculated upon the occurrence or non-occurrence of such specified events using the figure to which such minimum amount of consideration is reduced; and

(C) if the minimum amount of consideration payable to the Corporation upon the exercise of such Rights or Options or the conversion or exchange of Convertible Securities is subsequently increased, then the Effective Price shall again be recalculated using the increased minimum amount of consideration payable to the Corporation upon the exercise of such Rights or Options or the conversion or exchange of such Convertible Securities.

No further adjustment of the Conversion Price, adjusted upon the issuance of such Rights or Options or Convertible Securities, shall be made as a result of the actual issuance of shares of Common Stock on the exercise of any such Rights or Options or the conversion or exchange of any such Convertible Securities. If any such Rights or Options or the conversion rights represented by

-13-

any such Convertible Securities shall expire without having been fully exercised, then the Conversion Price as adjusted upon the issuance of such Rights or Options or Convertible Securities shall be readjusted to the Conversion Price which would have been in effect had an adjustment been made on the basis that the only shares of Common Stock so issued were the shares of Common Stock, if any, that were actually issued or sold on the exercise of such Rights or Options or rights of conversion or exchange of such Convertible Securities, and such shares of Common Stock, if any, were issued or sold for the consideration actually received by the Corporation upon such exercise, plus the consideration, if any, actually received by the Corporation for the granting of all such Rights or Options, whether or not exercised, plus the consideration received for issuing or selling all such Convertible Securities actually converted or exchanged, plus the consideration, if any, actually received by the Corporation (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) on the conversion or exchange of such Convertible Securities, provided that such readjustment shall not apply to prior conversions of Series B Preferred Stock.

(e) Successive Adjustments. Successive adjustments in the Conversion Price shall be made, without duplication, whenever any event specified in Sections 7(c)(i), 7(c)(ii), 7(c)(iii), 7(c)(iv) or 7(d) hereof shall occur.

(f) Rounding of Calculations; Minimum Adjustments. All calculations under Section 7(c) or Section 7(d) shall be made to the nearest one-tenth (1/10th) of a cent. No adjustment in the Conversion Price is required if the amount of such adjustment would be less than $0.01; provided, however, that any adjustments which by reason of this Section 7(f) are not required to be made will be carried forward and given effect in any subsequent adjustment.

(g) Adjustment for Unspecified Actions. If the Corporation takes any action affecting the Common Stock, other than an action described in Section 7(c) or Section 7(d), which in the opinion of the Board would materially adversely affect the conversion rights of the holders of shares of Series B Preferred Stock, the Conversion Price may be adjusted, to the extent permitted by law, in such manner and at such time, as the Board may determine in good faith to be equitable in the circumstances.

(h) Statement Regarding Adjustments. Whenever the Conversion Price shall be adjusted as provided in Section 7(c) or Section 7(d), the Corporation shall forthwith file, at the principal office of the Corporation, a statement showing in reasonable detail the facts requiring such adjustment and the Conversion Price that shall be in effect after such adjustment and the Corporation shall also cause a copy of such statement to be sent by mail, first class postage prepaid, to each holder of shares of Series B Preferred Stock at the address appearing in the Corporation’s records.

(i) Notices. In the event that the Corporation shall give notice or make a public announcement to the holders of Common Stock of any action of the type described in Section 7(c) or Section 7(d) or in Section 4 or Section 5 hereof, the Corporation shall, at the time of such notice or announcement, and in the case of any action which would require the fixing of a record date, at least ten (10) days prior to such record date, give notice to the holders of shares of Series B Preferred Stock, in the manner set forth in Section 7(h), which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Conversion Price and the number, kind or class of shares or other

-14-

securities or property which shall be deliverable upon conversion of the Series B Preferred Stock. All notices to the Corporation permitted hereunder shall be personally delivered or sent by first class mail, postage prepaid, addressed to its principal office located at 124 Floyd Smith Drive, Suite 300, Charlotte, North Carolina 28262, or to such other address at which its principal office is located and as to which notice thereof is similarly given to the holders of the Series B Preferred Stock at their addresses appearing on the books of the Corporation.

8. AMENDMENT. This Certificate of Designations, Preferences and Rights may only be amended with the prior written consent of at least a majority of the then outstanding shares of Series B Preferred Stock.
