The Corporation shall mail written notice of any such Liquidation, not less than 30 days prior to the payment date stated therein, to each record Holder.

Section 6.                                            Conversion.

a)                                      Conversions at Option of Holder. Each share of Preferred Stock shall be convertible into that number of shares of Common Stock (subject to the limitations set forth in Sections 6(c) and (d)) determined by dividing the Stated Value of such share of Preferred Stock by the Conversion Price, at the option of the Holder, at any time and from time to time from and after the Original Issue Date. Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number of shares of Preferred Stock to be converted, the number of shares of Preferred Stock owned prior to the conversion at issue, the number of shares of Preferred Stock owned subsequent to the conversion at issue and the date on which such conversion is to be effected, which date may not be prior to the date the Holder delivers such Notice of Conversion to the Corporation by facsimile (the “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion to the Corporation is deemed delivered hereunder. The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error.  To effect conversions, as the case may be, of shares of Preferred Stock, a Holder shall not be required to surrender the certificate(s) representing such shares of Preferred Stock to the Corporation unless all of the shares of Preferred Stock represented thereby are so converted, in which case the Holder shall deliver the certificate representing such share of Preferred Stock promptly following the Conversion

9

Date at issue.  Shares of Preferred Stock converted into Common Stock or redeemed in accordance with the terms hereof shall be canceled and may not be reissued.

b)                                     Conversion Price.  The conversion price for the Preferred Stock shall equal $2.50 (the “Conversion Price”), subject to adjustment herein.

c)                                      Beneficial Ownership Limitation.  The Corporation shall not effect any conversion of the Preferred Stock, and the Holder shall not have the right to convert any portion of the Preferred Stock to the extent that after giving effect to such conversion, the Holder (together with the Holder’s affiliates), as set forth on the applicable Notice of Conversion, would beneficially own in excess of 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such conversion.  For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of the Preferred Stock with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted Stated Value of Preferred Stock beneficially owned by the Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Corporation (including the Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates.  Except as set forth in the preceding sentence, for purposes of this Section 6(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act.  To the extent that the limitation contained in this Section 6(c) applies, the determination of whether the Preferred Stock is convertible (in relation to other securities owned by the Holder together with any affiliates) and of which shares of Preferred Stock is convertible shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Preferred Stock may be converted (in relation to other securities owned by such Holder) and which shares of the Preferred Stock is convertible, in each case subject to such aggregate percentage limitations. To ensure compliance with this restriction, the Holder will be deemed to represent to the Corporation each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph and the Corporation shall have no obligation to verify or confirm the accuracy of such determination.  For purposes of this Section 6(c), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in the most recent of the following: (A) the Corporation’s most recent Form 10-Q or Form 10-K, as the case may be, (B) a more recent public announcement by the Corporation or (C) any other notice by the Corporation or the Corporation’s transfer agent setting forth the number of shares of Common Stock outstanding.  Upon the written or oral request of the Holder, the Corporation shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to

10

the conversion or exercise of securities of the Corporation, including the Preferred Stock, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported.  The provisions of this Section 6(c) may be waived by the Holder, at the election of the Holder, upon not less than 61 days’ prior notice to the Corporation, and the provisions of this Section 6(c) shall continue to apply until such 61^st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver).  Notwithstanding any of the foregoing, the foregoing provisions of this Section 6(c) shall not apply to any Holder who is an officer or director of the Corporation as of the Closing Date or as of the date of conversion. In addition, if the Holder is an officer or director of the Company as of the Original Issue Date, such Holder may not convert any of his shares of Preferred Stock into shares of Common Stock or receive any shares of Common Stock in connection with a Triggering Event unless and until the issuance of such shares is approved by the Company’s stockholders, to the extent required by the rules and regulations of the Nasdaq Stock Market.

d)                                     Limitation on Number of Shares Issuable.  Notwithstanding anything herein to the contrary, the Corporation shall not issue to any Holder any shares of Common Stock, including pursuant to any rights herein, including, without limitation, any conversion rights, to the extent such shares, when added to the number of shares of Common Stock issued (A) upon conversion of any shares of Preferred Stock pursuant to Section 6(a) and (B) upon exercise of those certain warrants issued pursuant to that certain Purchase Agreement would exceed 1,211,605 shares of Common Stock immediately prior to the Closing Date, or such greater number of shares of Common Stock permitted pursuant to the corporate governance rules of the Nasdaq Stock Market that is at the time the principal trading exchange or market for the Common Stock, based upon share volume, as confirmed in writing by counsel to the Corporation (the “Maximum Aggregate Share Amount”), unless the Corporation first obtains shareholder approval permitting such issuances in accordance with the Nasdaq Market Place Rule 4350 (“Shareholder Approval”).  Each Holder shall be entitled to a portion of the Maximum Aggregate Share Amount equal to the quotient obtained by dividing (x) such the number of shares of Preferred Stock initially purchased by such Holder by (y) the aggregate number of shares purchased by all Holders.  Such portions shall be adjusted upward ratably in the event all of the shares of Preferred Stock of any Holder are no longer outstanding.  If at any time the number of shares of Common Stock which could, notwithstanding the limitation set forth herein, be issuable and sold to all Holders during the following 12 months equals or exceeds the Maximum Aggregate Share Amount, then the Corporation shall, subject to any requirements in the Purchase Agreement to act sooner, obtain the Shareholder Approval applicable to such issuance as soon as is possible, but in any event not later than the 75th day after the date in which the Corporation determines (or is notified by any Holder) that the Maximum Aggregate Share Amount could be exceeded and shall continue to seek to obtain Shareholder Approval every 75 days until such Shareholder Approval is obtained.

11

After the Effective Date, the Corporation shall, upon request of the Holder, deliver any certificate or certificates representing Common Stock required to be delivered by the Corporation under this Section electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions. If in the case of any Notice of Conversion such certificate or certificates are not delivered to or as directed by the applicable Holder by the third Trading Day after the Conversion Date, the Holder shall be entitled to elect by written notice to the Corporation at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, in which event the Corporation shall immediately return the certificates representing the shares of Preferred Stock tendered for conversion.

ii.                                       Obligation Absolute; Partial Liquidated Damages.  The Corporation’s obligations to issue and deliver the Conversion Shares upon conversion of Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the 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 the Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by the Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to the Holder in connection with the issuance of such Conversion Shares.  In the event a Holder shall elect to convert any or all of the Stated Value of its Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or any one associated or affiliated with the Holder of has been engaged in any violation of law, agreement or for any other reason, unless, an injunction from a court, on notice, restraining and or enjoining conversion of all or part of this Preferred Stock shall have been sought and obtained and the Corporation posts a surety bond for the benefit of the Holder in the amount of 150% of the Stated Value of Preferred Stock outstanding, which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment.  In the absence of an injunction precluding the same, the Corporation shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion. If the Corporation fails to deliver to the Holder such certificate or certificates pursuant to Section 6(e)(i) within two Trading Days of the Share Delivery Date applicable to such

12

conversion, the Corporation shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $5,000 of Stated Value of Preferred Stock being converted, $50 per Trading Day (increasing to $100 per Trading Day after 3 Trading Days and increasing to $200 per Trading Day 6 Trading Days after such damages begin to accrue) for each Trading Day after the Share Delivery Date until such certificates are delivered. Nothing herein shall limit a Holder’s right to pursue actual damages for the Corporation’s failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

iii.                                    Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. If the Corporation fails to deliver to the Holder such certificate or certificates pursuant to Section 6(e)(i) by a Share Delivery Date, and if after such Share Delivery Date the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Corporation shall pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the price at which the sell order giving rise to such purchase obligation was executed. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Preferred Stock with respect to which the aggregate sale price giving rise to such purchase obligation is $10,000, under clause (A) of the immediately preceding sentence the Corporation shall be required to pay the Holder $1,000. The Holder shall provide the Corporation written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Corporation. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Preferred Stock as required pursuant to the terms hereof.

iv.                                   Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of the Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder (and the other Holders of the Preferred Stock), not less than such number of shares of the Common Stock

13

as shall (subject to any additional requirements of the Corporation as to reservation of such shares set forth in the Purchase Agreement) be issuable (taking into account the adjustments and restrictions of Section 7) upon the conversion of all outstanding shares of Preferred Stock.  The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid, nonassessable and, if the Conversion Shares Registration Statement is then effective under the Securities Act, registered for public sale in accordance with such Conversion Shares Registration Statement.

v.                                      Fractional Shares. Upon a conversion hereunder, the Corporation shall not be required to issue stock certificates representing fractions of shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the VWAP at such time.  If the Corporation elects not, or is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

vi.                                   Transfer Taxes.  The issuance of certificates for shares of the Common Stock on conversion of this Preferred Stock shall be made without charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Holder of such shares of Preferred Stock so converted and the Corporation shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

Section 7.                                            Certain Adjustments.

a)                                      Stock Dividends and Stock Splits.  If the Corporation, at any time while this Preferred Stock is outstanding: (A) pays a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation pursuant to this Preferred Stock) or any distribution made in connection with any liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, including any Liquidation under Section 5, (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issues by reclassification of shares of the Common Stock any shares of capital stock of the Corporation, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if

14

any) 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 this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b)                                     [RESERVED].

c)                                      Subsequent Rights Offerings.  If the Corporation, at any time while the Preferred Stock is outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to Holders) entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the VWAP at the record date mentioned below, then the Conversion Price shall be multiplied by a fraction, of which the denominator shall be the number of shares of the Common Stock Outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock Outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming receipt by the Corporation in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such VWAP.  Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options or warrants.

d)                                     Pro Rata Distributions. If the Corporation, at any time while Preferred Stock is outstanding, shall distribute to all holders of Common Stock (and not to Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security, then in each such case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors in good faith.  In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock.  Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

e)                                      Fundamental Transaction. If, at any time while this Preferred Stock is outstanding, (A) the Corporation effects any merger or consolidation of the Corporation with or into another Person (other than a merger or consolidation that does not result in

15

any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the Corporation), (B) the Corporation effects any sale of all or substantially all of its assets in one or a series of related transactions, (C) any tender offer or exchange offer (whether by the Corporation or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (D) the Corporation effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, in each case which does not otherwise constitute a Liquidation (in any such case, a “Fundamental Transaction”), then upon any subsequent conversion of this Preferred Stock, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash or property as it would 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 Conversion Price 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 the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this 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, as the case may be, shall make provisions in its certificate or articles of incorporation or other constituent document to provide the Holder with new preferred stock or other equity security consistent with the foregoing provisions and evidencing the Holder’s 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 Section 7(e) and insuring that this Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

f)                                        Calculations.  All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.  For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

16

g)                                     Notice to Holders.

i.                                          Adjustment to Conversion Price.  Whenever the Conversion Price is adjusted pursuant to any of this Section 7, the Corporation shall promptly mail to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

ii.                                       Notice to Allow Conversion by Holder.  If (A) the Corporation shall declare a dividend (or any other distribution) on the Common Stock; (B) the Corporation shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock (other than repurchases of shares of Common Stock from employees, officers, directors, consultants or other persons performing services for the Corporation or any subsidiary pursuant to agreements under which the Corporation has the option to repurchase such shares upon the happening of certain events, such as termination in an aggregate amount not to exceed $100,000); (C) the Corporation shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights; (D) the approval of any stockholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, of any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property; (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation; then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of this Preferred Stock, and shall cause to be mailed to the Holder at its last address as its shall appear upon the stock books of the Corporation, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided, that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice.  The Holder is entitled to convert the Conversion Amount of this Preferred Stock (or any part hereof) during the 20-day period commencing the date of such notice to the effective date of the event triggering such notice.

17

Section 8.                                            Forced Conversion

a)                                      Forced Conversion.  Notwithstanding anything herein to the contrary, if after the 12 month anniversary of the Original Issue Date and after the Effective Date the VWAP for each of any 20 consecutive Trading Days (“Threshold Period”), which 20 consecutive Trading Day period shall have commenced only after the Effective Date, exceeds 200% of the then effective Conversion Price, the Corporation may, within 1 Trading Day after any such Threshold Period, deliver a notice to all Holders (a “Forced Conversion Notice” and the date such notice is received by the Holders, the “Forced Conversion Notice Date”) to cause each Holder to immediately convert up to such Holder’s entire remaining number of shares of Preferred Stock.  The Corporation may only effect a Forced Conversion Notice if all of the Equity Conditions have been met during the Threshold Period through the Forced Conversion Notice Date.  Any Forced Conversion Notices shall be applied ratably to all of the Holders in proportion to each Holder’s initial purchases of Preferred Stock hereunder, provided that any voluntary conversions by a Holder shall be applied against such Holder’s pro-rata allocation thereby decreasing the aggregate amount forcibly converted hereunder.  Immediately upon the Forced Conversion Notice Date, each outstanding share of Preferred Stock shall be converted automatically without any further action by the Holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent; provided, however, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion unless the certificates evidencing such shares of Preferred Stock are delivered to the Corporation in accordance with the following sentence.  Upon Forced Conversion Notice Date, the Holders of Preferred Stock shall surrender the certificates representing such shares at the office of the Corporation in accordance with Section 6(a); provided that the Holders shall have no obligation to deliver a Notice of Conversion.  Thereupon, there shall be issued and delivered to each Holder within three (3) Trading Days and in its name as shown on such surrendered certificate or certificates, a certificate or certificates for the number of shares of Common Stock into which the shares of Preferred Stock surrendered were convertible upon the Forced Conversion Notice Date.

18

Securities under the Conversion Shares Registration Statement for more than an aggregate of 90 calendar days (which need not be consecutive days) during any 12 month period;

iii.                                                the Corporation shall fail to deliver certificates representing Conversion Shares issuable upon a conversion hereunder that comply with the provisions hereof prior to the 10^th Trading Day after such shares are required to be delivered hereunder, or the Corporation shall provide written notice to any Holder, including by way of public announcement, at any time, of its intention not to comply with requests for conversion of any shares of Preferred Stock in accordance with the terms hereof;

iv.                                               one of the Events (as defined in the Registration Rights Agreement) described in subsections (i), (ii) or (iii) of Section 2(b) of the Registration Rights Agreement shall not have been cured to the satisfaction of the Holders prior to the expiration of 60 days from the Event Date (as defined in the Registration Rights Agreement) relating thereto (other than an Event resulting from a failure of a Conversion Shares Registration Statement to be declared effective by the Commission on or prior to the 230th day after the Original Issue Date, which shall be covered by Section 9(a)(i));

v.                                                  the Corporation shall fail for any reason to pay in full the amount of cash due pursuant to a Buy-In within 10 days after notice therefor is delivered hereunder or shall fail to pay all amounts owed on account of an Event within five days of the date due;

vi.                                               the Corporation shall fail to have available a sufficient number of authorized and unreserved shares of Common Stock to issue to such Holder upon a conversion hereunder;

vii.                                            the Corporation shall fail to observe or perform any other covenant, agreement or warranty contained in, or otherwise commit any breach of the Transaction Documents, and such failure or breach shall not, if subject to the possibility of a cure by the Corporation, have been remedied within 45 calendar days after the date on which written notice of such failure or breach shall have been given;

viii.                                         the Corporation shall redeem more than a de minimis number of Junior Securities other than as a result of the conversion into or exchange for Junior Securities or in connection with repurchases of shares of Common Stock from employees, officers, directors, consultants or other persons performing services for the Corporation or any subsidiary pursuant to agreements under which the Corporation has the option to repurchase such shares upon the happening of certain events, such as termination, in an aggregate amount not to exceed $100,000 per calendar year;

xii.                                              any breach of the agreements delivered to the initial Holders at the Closing pursuant to Section 2.2(a)(vii) of the Purchase Agreement.

b)                                     Upon the occurrence of a Triggering Event, each Holder shall (in addition to all other rights it may have hereunder or under applicable law) have the right, exercisable at the sole option of such Holder, to require the Corporation to, (i) with respect to the Triggering Events set forth in Sections 9(a) (iii), (v), (vii), (ix) and (x)(as to voluntary filings only)), redeem all of the Preferred Stock then held by such Holder for a redemption price, in cash, equal to the Triggering Redemption Amount; or, (ii) at the option of the Holder and with respect to the Triggering Events set forth in Sections 9(a)(i), (ii), (iv), (vi), (viii), (x)(as to involuntary filings only), (xi) and (xii), either (A) redeem all of the Preferred Stock then held by such Holder for a redemption price, in shares of Common Stock, equal to a number of shares of Common Stock equal to the Triggering Redemption Amount divided by 75% of the average of the 10 VWAPs immediately prior to the date of election hereunder or (B) increase the dividend on all of the outstanding Preferred Stock held by such Holder to equal 18% per annum thereafter; provided, however, the Holder shall only have the option of Section 9(b)(ii)(A) after the Corporation has obtained Shareholder Approval as required by Section 6(d) and, if the Corporation has not obtained such Shareholder Approval), Section 9(b)(ii)(B) shall automatically apply irrespective of such Holder’s option.  The Triggering Redemption Amount, if in cash or in shares, shall be due and payable or issuable, as the case may be, within 5 Trading Days of the date on which the notice for the payment therefor is provided by a Holder (the “Triggering Redemption Payment Date”).  If the Corporation fails to pay the Triggering Redemption Amount hereunder in full pursuant to this Section on the date such amount is due in accordance with this Section (whether in cash or shares of Common Stock), the Corporation will pay interest thereon at a rate of 18% per annum (or such lesser amount permitted by applicable law), accruing daily from such date until the Triggering Redemption Amount, plus all such interest thereon, is paid in full.  For purposes of this Section, a share of Preferred Stock is outstanding until such date as the Holder shall have received Conversion Shares upon a conversion (or attempted conversion) thereof that meets the requirements hereof or has been paid the Triggering Redemption Amount plus all accrued but unpaid dividends and all accrued but unpaid liquidated damages in cash.
