A123 SYSTEMS, INC.

SENIOR CONVERTIBLE NOTE

Issuance Date: May [ ], 2012

Original Principal Amount: U.S. $[ ]

FOR VALUE RECEIVED, A123 Systems, Inc., a Delaware corporation (the “Company”), hereby promises to pay to [BUYER] or registered assigns (the “Holder”) the amount set out above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined below), on any Installment Date with respect to the Installment Amount due on such Installment Date, acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the applicable Interest Rate from the date set out above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon an Interest Date (as defined below), any Installment Date, the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Convertible Note (including all Senior Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”) is one of an issue of Senior Convertible Notes issued pursuant to the Securities Purchase Agreement on the Closing Date (collectively, the “Notes” and such other Senior Convertible Notes, the “Other Notes”). Certain capitalized terms used herein are defined in Section 30.

(1) PAYMENTS OF PRINCIPAL; PREPAYMENT. On each Installment Date (which includes the Maturity Date), the Company shall pay to the Holder an amount equal to the Installment Amount due on such Installment Date in accordance with Section 8. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal and accrued and unpaid Interest. The “Maturity Date” shall be July 15, 2013, as may be extended at the option of the Holder (i) in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1) or any event shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1) that with the passage of time and the failure to cure would result in an Event of Default and (ii) through the date that is ten (10) Business Days after the consummation of a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section 5(b)) is delivered prior to the Maturity Date. Other than as specifically permitted by this Note, the Company may not prepay any portion of the outstanding Principal or accrued and unpaid Interest, if any.

(2) INTEREST; INTEREST RATE.

(a) Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year and twelve 30-day months and shall be payable in arrears on the first (1st) and fifteenth (15th) day of each calendar month after the Issuance Date or, if any such date falls on a Holiday, the next day that is not a Holiday (each, an “Interest Date”) with the first (1st) Interest Date being July 1, 2012. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in shares of Common Stock (“Interest Shares”) so long as there has been no Equity Conditions Failure; provided, however, that the Company may, at its option following notice to the Holder, pay Interest on any Interest Date in cash (“Cash Interest”) or in a combination of Cash Interest and Interest Shares. The Company shall deliver a written notice (each, an “Interest Election Notice”) to each holder of the Notes on or prior to the applicable Interest Notice Due Date (the date such notice is delivered to all of the holders of Notes, the “Interest Notice Date”) which notice (i) either (A) confirms that Interest to be paid on such Interest Date shall be paid entirely in Interest Shares, or (B) elects to pay Interest as Cash Interest or a combination of Cash Interest and Interest Shares and specifies the amount of Interest that shall be paid as Cash Interest and the amount of Interest, if any, that shall be paid in Interest Shares, and (ii) certifies that there has been no Equity Conditions Failure as of such Interest Notice Date. If there is an Equity Conditions Failure as of the Interest Notice Date, then unless the Company has elected to pay such Interest as Cash Interest, the Interest Notice shall indicate that unless the Holder waives the Equity Conditions, the Interest shall be paid as Cash Interest. If the Company confirmed the payment of the applicable Interest in Interest Shares, in whole or in part, and if the Equity Conditions were satisfied as of the applicable Interest Notice Date but an Equity Conditions Failure occurred between the applicable Interest Notice Date and any time prior to the applicable Interest Date, the Company shall provide the Holder a subsequent notice to that effect indicating that unless the Holder waives the Equity Conditions, the Interest shall be paid in cash. If the Equity Conditions are not satisfied (or waived in writing by the Holder) during such period, then at the option of the Holder, the Holder may require the Company to pay the amount of Interest payable on the applicable Interest Date as Cash Interest. Interest to be paid on an Interest Date in Interest Shares shall be paid in a number of fully paid and nonassessable shares (rounded to the

nearest whole share in accordance with Section 3(a)) of Common Stock equal to the quotient of (1) the amount of Interest payable on such Interest Date less any Cash Interest paid, and (2) the Company Conversion Price in effect on the applicable Interest Date.

(b) When any Interest Shares are to be paid on an Interest Date, the Company shall, on the applicable Interest Date (i) (A) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of Interest Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal At Custodian system, or (B) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver, to the address set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at least two (2) Business Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled, and (ii) with respect to each Interest Date, pay to the Holder, in cash by wire transfer of immediately available funds, the amount of any Cash Interest.

(c) Prior to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount on each Conversion Date in accordance with Section 3(b)(i). From and after the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to sixteen and one-half percent (16.5%). In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided, that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default. The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of Interest Shares.

(3) CONVERSION OF NOTES. At any time or times after the Issuance Date, this Note shall be convertible into shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), on the terms and conditions set forth in this Section 3.

(a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and nonassessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

(b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be

determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

(i) “Conversion Amount” means the sum of (A) the portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made and (B) accrued and unpaid Interest with respect to such portion of the Principal.

(ii) “Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, $1.18, subject to adjustment as provided herein.

(i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the Company and the Transfer Agent and (B) if required by Section 3(c)(iii), surrender this Note to a common carrier for delivery to the Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the first (1st) Business Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Transfer Agent. On or before the third (3rd) Trading Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (x) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit such aggregate 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 At Custodian system or (y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. If required by Section 3(c)(iii), within three (3) Business Days following a conversion of this Note, the Holder shall surrender this Note (or deliver an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction as contemplated by Section 18(b)) to the Company. If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the Holder a new Note (in accordance with Section 18(d)) representing the outstanding Principal not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of

Common Stock on the Conversion Date, irrespective of the date such Conversion Shares are credited to the Holder’s account with DTC or the date of delivery of the certificates evidencing such Conversion Shares, as the case may be. In the event that the Holder elects to convert the Company Conversion Amount (as defined in Section 8(a)) prior to the applicable Installment Date as set forth in Section 8(b), the Company Conversion Amount so converted shall be deducted from the final Installment Amounts to be paid hereunder on the final Installment Date, unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in the applicable Conversion Notice.

(ii) Company’s Failure to Timely Convert. If the Company shall fail to issue a certificate to the Holder or credit the Holder’s balance account with DTC, as applicable, for the number of shares of Common Stock to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the Share Delivery Date (a “Conversion Failure”), then (A) the Company shall pay damages to the Holder for each Trading Day of such Conversion Failure in an amount equal to 1.5% of the product of (1) the sum of the number of shares of Common Stock not issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, and (2) the Closing Sale Price of the Common Stock on the Share Delivery Date and (B) the Holder, upon written notice to the Company, may void its Conversion Notice with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to such Conversion Notice; provided that the voiding of a Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(ii) or otherwise. In addition to the foregoing, if the Company shall fail on or prior to the Share Delivery Date to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion of any Conversion Amount or on any date of the Company’s obligation to deliver shares of Common Stock as contemplated pursuant to clause (ii) below, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to issue and deliver such certificate or credit the Holder’s balance account with DTC for the shares of Common Stock to which the Holder is entitled upon the Holder’s conversion of the applicable Conversion Amount shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Stock or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Sale Price on the Conversion Date.

(iii) Registration; Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the “Registered Notes”). The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the owner of a Note for all purposes, including, without limitation, the right to receive payments of Principal and Interest, if any, hereunder, notwithstanding notice to the contrary. A Registered Note may be assigned or sold in whole or in part only by registration of such assignment or sale on the Register. Upon its receipt of a written request to assign or sell all or part of any Registered Note by a Holder, together with any required documentation under the Transaction Documents (as defined in the Securities Purchase Agreement) including any legal opinions, if applicable, the Company shall record the information contained therein in the Register and issue one or more new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered Registered Note to the designated assignee or transferee pursuant to Section 18. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Principal amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal and Interest, if any, converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

(iv) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 23.

(d) Limitations on Conversions.

(i) Beneficial Ownership. The Company shall not effect any conversion of this Note, and the Holder of this Note shall not have the right to convert any portion of this Note pursuant to the terms and conditions of this Note, to the extent that after giving effect to such conversion, the Holder (together with the Holder’s Affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the number of shares of 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 this Note 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 portion of this Note 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 Company (including, without limitation, any Other Notes or 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 3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of this Section 3(d)(i), 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 (x) the Company’s most recent Form 10-K, Form 10-Q, Form 8-K or other public filing with the SEC, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day 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 the conversion or exercise of securities of the Company, including this Note, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3(d)(i) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

(ii) Principal Market Regulation. The Company shall not issue any shares of Common Stock under this Note (whether upon conversion of this Note, as Interest Shares, as payment of any Installment Amount or otherwise), and the Holder shall not have the right to receive any shares of Common Stock, if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue pursuant to the terms of the Notes without breaching the Company’s obligations under the rules or regulations of the Principal Market (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such

approval is not required, which opinion shall be reasonably satisfactory to the Required Holders. Until such approval or written opinion is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (the “Purchasers”) shall be issued in the aggregate, upon conversion of Notes or as Interest Shares, or as payment of any Installment Amount hereunder or otherwise, shares of Common Stock in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the principal amount of Notes issued to such Purchaser pursuant to the Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate principal amount of all Notes issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”). In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of Notes shall convert all of such holder’s Notes into a number of shares of Common Stock which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder.

(4) RIGHTS UPON EVENT OF DEFAULT.

(a) Event of Default. Each of the following events shall constitute an “Event of Default”:

(i) Intentionally omitted.

(ii) the suspension from trading or failure of the Common Stock to be listed on an Eligible Market for a period of five (5) consecutive Trading Days or for more than an aggregate of ten (10) Trading Days in any 365-day period;

(iii) the Company’s (A) failure to cure a Conversion Failure by delivery of the required number of shares of Common Stock within ten (10) Business Days after the applicable Conversion Date or (B) notice, written or oral, to any holder of the Notes, including by way of public announcement or through any of its agents, at any time, of its intention not to comply with a request for conversion of any Notes into shares of Common Stock that is tendered in accordance with the provisions of the Notes, other than pursuant to Section 3(d);

(iv) at any time following the tenth (10th) consecutive Business Day that the Holder’s Authorized Share Allocation is less than the number of shares of Common Stock that the Holder would be entitled to receive upon a conversion of the full Conversion Amount of this Note (without regard to any limitations on conversion set forth in Section 3(d) or otherwise);

(v) the Company’s failure to pay to the Holder any amount of Principal, Interest or other amounts when and as due under this Note (including, without limitation, the Company’s failure to pay any redemption amounts hereunder) or, subject to the delivery of written notice by the Holder to the Company, pursuant to any other Transaction Document (as defined in the Securities Purchase Agreement) or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated hereby and thereby to which the Holder is a party, except, in the case of a failure to pay Interest when and as due, in which case only if such failure continues for a period of at least five (5) Business Days;

(vi) any default under, redemption of or acceleration prior to maturity of an aggregate amount of Indebtedness in excess of $1,000,000 of the Company or any of its Subsidiaries (as defined in Section 3(a) of the Securities Purchase Agreement) other than with respect to any Other Notes;

(vii) the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal, foreign or state law for the relief of debtors (collectively, “Bankruptcy Law”), (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a receiver, trustee, assignee, liquidator or similar official (a “Custodian”), (D) makes a general assignment for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due;

(viii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the Company or any of its Subsidiaries in an involuntary case, (B) appoints a Custodian of the Company or any of its Subsidiaries or (C) orders the liquidation of the Company or any of its Subsidiaries;

(ix) a final judgment or judgments for the payment of money aggregating in excess of $500,000 are rendered against the Company or any of its Subsidiaries and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; provided, however, that any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $500,000 amount set forth above so long as the Company provides the Holder a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment;

(x) other than as specifically set forth in another clause of this Section 4(a), the Company breaches any representation, warranty, covenant or other term or condition of any Transaction Document, except, in the case of a breach of a covenant or other term or condition of any Transaction Document which is curable, only if such breach continues for a period of at least ten (10) consecutive Business Days;

(xi) any breach or failure in any respect to comply with Section 15 of this Note;

(xii) the Company shall fail to perform or comply with any covenant or agreement contained in the Control Agreement or any material provision of the Control Agreement shall at any time for any reason cease to be valid and binding on or enforceable against the Company or the validity or enforceability thereof shall be contested by any party thereto, or a proceeding shall be commenced by the Company or any governmental authority having jurisdiction over the Company, seeking to establish the invalidity or unenforceability thereof;

(xiii) any bank at which the Collateral Account is maintained shall fail to comply with any material term of the Collateral Agreement or similar agreement to which such bank is a party; or

(xiv) any Event of Default (as defined in the Other Notes) occurs with respect to any Indebtedness, including, without limitation, with respect to the Other Notes.

(b) Redemption Right. Upon the occurrence of an Event of Default with respect to this Note or any Other Note, the Company shall within two (2) Business Days of such Event of Default deliver written notice thereof via facsimile and overnight courier (an “Event of Default Notice”) to the Holder. At any time after the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem (an “Event of Default Redemption”) all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to require the Company to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company in cash by wire transfer of immediately available funds at a price equal to the greater of (i) the product of (A) the Conversion Amount to be redeemed, multiplied by (B) the Redemption Premium and (ii) the product of (A) the Conversion Rate in effect at such time as the Holder delivers an Event of Default Redemption Notice with respect to the Conversion Amount to be redeemed, multiplied by (B) the greatest Closing Sale Price of the shares of Common Stock during the period beginning on the date immediately preceding such Event of Default and ending on the date the Holder delivers the Event of Default Redemption Notice (the “Event of Default Redemption Price”). Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 12. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. In the event of a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted from the final Installment Amounts to be paid hereunder on the final Installment Date, unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in the applicable Event of Default Redemption Notice. The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment

opportunity for the Holder. Accordingly, any Event of Default redemption premium due under this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

(5) RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.

(a) Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing (or, if prior to the consummation of such Fundamental Transaction, such applicable agreement requires the assumption of) all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes then outstanding held by such holder, having similar conversion rights and having similar ranking to the Notes, and satisfactory to the Required Holders. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Company’s Common Stock (or other securities, cash, assets or other property) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity (including its Parent Entity) (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital stock and such conversion price for the purpose of protecting the economic value of this Note immediately prior to the consummation of such Fundamental Transaction), as adjusted in accordance with the provisions of this Note. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion or redemption of this Note.

(b) Redemption Right. No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Change of Control Notice”). At any time during the period beginning on the earlier to occur of (x) any oral or written agreement by the Company or any of its Subsidiaries upon consummation of which the transaction contemplated thereby would reasonably be expected to result in a Change of Control and (y) the Holder’s receipt of a Change of Control Notice and ending twenty (20) Trading Days after the date of the

consummation of such Change of Control, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control Redemption Notice” and the date the Company receives such notice, the “Change of Control Redemption Notice Date”) to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to require the Company to redeem. The portion of this Note subject to redemption pursuant to this Section 5(b) shall be redeemed by the Company in cash by wire transfer of immediately available funds at a price equal to 100% of the greater of (i) the sum of (A) the Conversion Amount being redeemed and (B) the Make-Whole Amount and (ii) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient determined by dividing (x) the greatest Closing Sale Price of the shares of Common Stock during the period beginning on the date immediately preceding the earlier to occur of (1) the consummation of the Change of Control and (2) the public announcement of such Change of Control and ending on the date the Holder delivers the Change of Control Redemption Notice, by (y) the lowest Conversion Price in effect during such period (the “Change of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 12 and shall have priority to payments to stockholders in connection with a Change of Control. To the extent redemptions required by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any interest thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 5(b) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. In the event of a partial redemption of this Note pursuant hereto, the Principal amount redeemed shall be deducted from the final Installment Amounts to be paid hereunder on the final Installment Date, unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in the applicable Change of Control Redemption Notice. The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any Change of Control redemption premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

(6) DISTRIBUTION OF ASSETS; RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

(a) Distribution of Assets. If the Company shall declare or make any dividend or other distributions of its assets (or rights to acquire its assets) to any or all holders of shares of Common Stock, by way of return of capital or otherwise (including without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (the “Distributions”), then the Holder will be entitled to such Distributions as if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately prior to the date on which a record is taken for such Distribution or, if no

such record is taken, the date as of which the record holders of Common Stock are to be determined for such Distributions (provided, however, that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (or beneficial ownership of such shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage).

(b) Purchase Rights. If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately prior to the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage, at which time the Holder shall be granted such right to the same extent as if there had been no such limitation).

(c) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note.

(7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

(a) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased.

(b) Other Events. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights of the Holder under this Note; provided that no such adjustment will increase the Conversion Price as otherwise determined pursuant to this Section 7.

(c) Voluntary Adjustment By Company. The Company may at any time during the term of this Note reduce the then current Conversion Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

(d) Floating Rate Conversion Price. The Holder may, at any time and from time to time on or after August 15, 2012, notify the Company by so indicating in one or more Conversion Notices of its election to convert all or any portion of the outstanding and unpaid Conversion Amount using a floating rate conversion price equal to 85% of the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the applicable Conversion Date (the “Floating Rate Conversion Price”) in lieu of the Conversion Price then in effect. The Holder shall not be permitted hereunder to specify any Floating Rate Conversion Price to convert a Conversion Amount that exceeds either (A) in the aggregate as to any given Trading Day, the product of (x) $3,500,000.00 and (y) the Holder Pro Rata Amount or (B) in the aggregate while the Notes are outstanding, the product of (x) $30,000,000.00 and (y) the Holder Pro Rata Amount. The Company may elect to deliver a written notice (a “Cash Floating Rate Conversion Price Notice”) by facsimile and overnight courier to all, but not less than all, of the holders of Notes no later than the first (1st) day of a calendar month (the “Cash Floating Rate Conversion Price Deadline”) notifying the Holder that to the extent the Holder elects to effect during such calendar month any conversions at the Floating Rate Conversion Price pursuant to this Section 7(d), the Company shall be required to honor such conversions by paying to the Holder cash on or prior to the Share Delivery Date by wire transfer of immediately available funds in an amount equal to 115% of the Conversion Amount so to be converted. For the avoidance of doubt, if the Holder shall not have received a Cash Floating Rate Conversion Price Notice by the applicable Cash Floating Rate Conversion Price Deadline, the Company shall be required to honor such conversions by delivering shares of Common Stock. Solely for purposes of clarification, in the event that the Holder elects to convert pursuant to this Section 7(d), the Principal amount of the Notes so converted shall be deducted from the final Installment Amounts

to be paid hereunder on the final Installment Date, unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in the applicable Conversion Notice(s).

(8) COMPANY CONVERSION OR REDEMPTION. On each Installment Date, the Company shall pay to the Holder of this Note the Installment Amount due on such date by converting all or some of such Installment Amount into Common Stock, provided there has been no Equity Conditions Failure, in accordance with this Section 8 (a “Company Conversion”); provided, however, that the Company may, at its option following notice to the Holder as set forth below, pay all or some of the Installment Amount by redeeming such Installment Amount in cash (a “Company Redemption”) or by any combination of a Company Conversion and a Company Redemption so long as all of the outstanding applicable Installment Amount due on any Installment Date shall be converted and/or redeemed by the Company on the applicable Installment Date, subject to the provisions of this Section 8.

(a) General. On or prior to the date which is the tenth (10th) consecutive Trading Day immediately prior to each Installment Date (each, an “Installment Notice Due Date”), the Company shall deliver written notice (each, a “Company Installment Notice” and the date all of the holders receive such notice is referred to as the “Company Installment Notice Date”), to each holder of Notes which Company Installment Notice shall (i) (1) either (A) confirm that the applicable Installment Amount of such holder’s Note shall be converted to Common Stock in whole or in part pursuant to a Company Conversion (such amount to be converted, the “Company Conversion Amount”) or (B) state that the Company elects to redeem for cash, or is required to redeem for cash in accordance with the provisions of the Notes, in whole or in part, the applicable Installment Amount pursuant to a Company Redemption and (2) specify the portion (including Interest, if any, on such amount) which the Company elects or is required to redeem pursuant to a Company Redemption (such amount to be redeemed, the “Company Redemption Amount”) and the portion (including Interest, if any, on such amount) that is the Company Conversion Amount, which amounts, when added together, must equal the applicable Installment Amount and (ii) if the Installment Amount is to be paid, in whole or in part, in Common Stock pursuant to a Company Conversion, certify that the Equity Conditions have been satisfied as of the Company Installment Notice Date. Each Company Installment Notice shall be irrevocable. If the Company does not timely deliver a Company Installment Notice in accordance with this Section 8, then the Company shall be deemed to have delivered an irrevocable Company Installment Notice confirming a Company Conversion and shall be deemed to have certified that the Equity Conditions in connection with any such conversion on the Company Installment Notice Date and Installment Date have been satisfied. Except as expressly provided in this Section 8(a), the Company shall convert and/or redeem the applicable Installment Amount of this Note pursuant to this Section 8 and the corresponding Installment Amounts of the Other Notes pursuant to the corresponding provisions of the Other Notes in the same ratio of the Installment Amount being converted and/or redeemed hereunder. The Company Conversion Amount (whether set forth in the Company Installment Notice or by operation of this Section 8) shall be converted in accordance with Section 8(b) and the Company Redemption Amount shall be redeemed in accordance with Section 8(c). Notwithstanding anything herein to the contrary, in the event of any partial conversion or redemption of this Note, the Principal amount converted or redeemed shall be deducted from the final Installment Amounts to be paid hereunder on the final Installment Date, unless the Holder otherwise

indicates and allocates among any Installment Dates hereunder in the applicable Conversion Notice or Redemption Notice, as applicable.

(b) Mechanics of Company Conversion. When the Company delivers a Company Installment Notice and confirms, or is deemed to have confirmed, in whole or in part, a Company Conversion in accordance with Section 8(a), then on the applicable Installment Date, provided, that the Equity Conditions have been satisfied (or waived in writing by the Holder) on such Installment Date, the Company shall, or shall direct the Transfer Agent to, credit the Holder’s account with DTC (or if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver the Holder a certificate), for a number of shares of Common Stock (the “Installment Shares”) equal to the quotient of (x) the Company Conversion Amount as of the applicable Installment Date divided by (y) the applicable Company Conversion Price. All Installment Shares shall be fully paid and nonassessable shares of Common Stock (rounded to the nearest whole share). If the Equity Conditions are not satisfied as of the Company Installment Notice Date, then unless the Company has elected to redeem such Installment Amount, the Company Installment Notice shall indicate that unless the Holder waives the Equity Conditions, the Installment Amount shall be redeemed in cash. If the Company confirmed (or is deemed to have confirmed by operation of Section 8(a)) the conversion of the applicable Company Conversion Amount, in whole or in part, and there was no Equity Conditions Failure as of the applicable Company Installment Notice Date (or is deemed to have certified that the Equity Conditions in connection with any such conversion have been satisfied by operation of Section 8(a)) but an Equity Conditions Failure occurred between the applicable Company Installment Notice Date and any time through the applicable Installment Date, the Company shall provide the Holder a subsequent notice to that effect. If the Equity Conditions are not satisfied (or waived in writing by the Holder) during such period, then at the option of the Holder designated in writing to the Company, the Holder may require the Company to do either one or both of the following: (i) the Company shall redeem all or any part designated by the Holder of the Company Conversion Amount (such designated amount is referred to as the “First Redemption Amount”) on such Installment Date and the Company shall pay to the Holder within three (3) Business Days of such Installment Date, by wire transfer of immediately available funds, an amount in cash equal to 125% of such First Redemption Amount and/or (ii) the Company Conversion shall be null and void with respect to all or any part designated by the Holder of the unconverted Company Conversion Amount and the Holder shall be entitled to all the rights of a holder of this Note with respect to such amount of the Company Conversion Amount with such Company Conversion Amount added to the final Installment Date, unless the Holder otherwise indicates; provided, however, that the Conversion Price for such unconverted Company Conversion Amount shall thereafter be adjusted to equal the lesser of (1) the Company Conversion Price as in effect on the date on which the Holder voided the Company Conversion and (2) the Company Conversion Price as in effect on the date on which the Holder delivers a Conversion Notice relating thereto. If the Company fails to redeem any First Redemption Amount by the third (3rd) Business Day following the applicable Installment Date by payment of such amount on the applicable Installment Date, then the Holder shall have the rights set forth in Section 12(a) as if the Company failed to pay the applicable Company Installment Redemption Price (as defined below) and all other rights under this Note (including, without limitation, such failure constituting an Event of Default described in Section 4(a)(v)). Notwithstanding anything to the contrary in this Section 8(b), but subject to the limitations set forth in Section 3(d), until the Company issues and delivers a certificate, or credits the Holder’s account with DTC, for the

shares of Common Stock representing the Company Conversion Amount to the Holder, the Company Conversion Amount may be converted by the Holder into Common Stock pursuant to Section 3. In the event that the Holder elects to convert the Company Conversion Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Company Conversion Amount so converted shall be deducted from the final Installment Amounts to be paid hereunder on the final Installment Date, unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in the applicable Conversion Notice.

(c) Mechanics of Company Redemption. If the Company elects a Company Redemption in accordance with Section 8, then the Company Redemption Amount which is to be paid to the Holder on the applicable Installment Date shall be redeemed by the Company and the Company shall pay to the Holder on such Installment Date, by wire transfer of immediately available funds, an amount in cash (the “Company Installment Redemption Price”) equal to 100% of the Company Redemption Amount. If the Company fails to redeem the Company Redemption Amount on the applicable Installment Date by payment of the Company Installment Redemption Price on such date, then at the option of the Holder designated in writing to the Company (any such designation shall be deemed a “Conversion Notice” pursuant to Section 3(c) for purposes of this Note), (i) the Holder shall have the rights set forth in Section 12(a) as if the Company failed to pay the applicable Company Installment Redemption Price and all other rights as a Holder of Notes (including, without limitation, such failure constituting an Event of Default described in Section 4(a)(v)) and (ii) the Holder may require the Company to convert all or any part of the Company Redemption Amount at the Company Conversion Price as in effect on the applicable Installment Date. Conversions required by this Section 8(c) shall be made in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(c), but subject to Section 3(d), until the Company Installment Redemption Price (together with any interest thereon) is paid in full, the Company Redemption Amount (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. In the event the Holder elects to convert all or any portion of the Company Redemption Amount prior to the applicable Installment Date as set forth in the immediately preceding sentence, the Company Redemption Amount so converted shall be deducted from the final Installment Amounts to be paid hereunder on the final Installment Date, unless the Holder otherwise indicates and allocates among any Installment Dates hereunder in the applicable Conversion Notice.

(9) OPTIONAL REDEMPTION AT THE HOLDER’S ELECTION. If (i) the Company has not obtained both the Stockholder Approval and the Authorized Share Stockholder Approval (each as defined in the Securities Purchase Agreement) on or prior to June 30, 2012 or (ii) the Initial Registration Statement (as defined in the Registration Rights Agreement) has not been declared effective on or prior to the ninetieth (90th) day after the Subscription Date registering at least the Initial Required Registration Amount of the Initial Registrable Securities (each as defined in the Registration Rights Agreement), but in no event registering less than one-third (1/3) of the Company’s Common Stock held by non-affiliates immediately prior to the Subscription Date, the Holder shall have the right, at any time thereafter, in its sole discretion, to require that the Company redeem all or any portion of a maximum of such Holder’s Pro Rata Amount of $25,000,000.00 of the outstanding aggregate Principal amount of this Note then outstanding (a “Holder Optional Redemption”) by delivering written notice thereof (a “Holder Optional Redemption Notice” and the date the Holder delivers such notice, the “Holder Optional Redemption Notice Date”) to the Company which notice shall state (i) the portion of this Note that is being redeemed up to the such Holder’s Pro Rata Amount of $25,000,000.00 and (ii) the date on which the Holder Optional Redemption shall occur which date shall be not less than five (5) Business Days from the Holder Optional Redemption Notice Date (the “Holder Optional

Redemption Date”). The portion of this Note subject to redemption pursuant to this Section 9 shall be redeemed by the Company in cash at a price (the “Holder Optional Redemption Price”) equal to 100% of the Conversion Amount being redeemed together with any accrued and unpaid Interest on such Conversion Amount and Interest through the Holder Optional Redemption Date. On the Holder Optional Redemption Date the Company shall deliver or shall cause to be delivered to the Holder the Holder Optional Redemption Price in cash by wire transfer of immediately available funds pursuant to wire instructions provided by the Holder in writing to the Company. If (i) both the Stockholder Approval and the Authorized share Stockholder Approval are obtained on or prior to June 30, 2012 and (ii) the Initial Registration Statement has been declared effective on or prior to the ninetieth (90th) day after the Subscription Date registering at least the Initial Required Registration Amount of the Initial Registrable Securities, but in no event registering less than one-third (1/3) of the Company’s Common Stock held by non-affiliates immediately prior to the Subscription Date, the Holder shall consent to release the funds in the Control Account pursuant to the terms and conditions of the Control Agreement. Holder Optional Redemptions made pursuant to this Section 9 shall be made in accordance with Section 12.

(10) NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note.

(11) RESERVATION OF AUTHORIZED SHARES.

(a) Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock for each of the Notes equal to 200% of the Conversion Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 200% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding; provided that at no time shall the number of shares of Common Stock so reserved be less than the number of shares required to be reserved by this sentence (without regard to any limitations on conversions) (the “Required Reserve Amount”). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the principal amount of the Notes held by each holder at the Closing (as defined in the Securities Purchase Agreement) or increase in the number of reserved shares, as the case may be (the “Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders.

(b) Insufficient Authorized Shares. If at any time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take

all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall either (x) obtain the written consent of its stockholders for the approval of an increase in the number of authorized shares of Common Stock and provide each stockholder with an information statement with respect thereto or (y) hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.

(12) REDEMPTIONS.

(a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five (5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice (the “Event of Default Redemption Date”). If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company shall deliver the applicable Change of Control Redemption Price to the Holder within thirty (30) days of the Change of Control Redemption Notice Date, provided, that the Change of Control Redemption Price shall be delivered concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control to the extent thirty (30) days have elapsed since the Change of Control Redemption Notice Date (such date, the “Change of Control Redemption Date”). The Company shall deliver the applicable Company Installment Redemption Price to the Holder on the applicable Installment Date. The Company shall deliver the Holder Optional Redemption Price to the Holder on the Holder Optional Redemption Date. The Company shall pay the applicable Redemption Price to the Holder in cash by wire transfer of immediately available funds on the applicable due date. In the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 18(d)) representing the outstanding Principal which has not been redeemed and any accrued Interest on such Principal which shall be calculated as if no Redemption Notice has been delivered. In the event that the Company does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable Redemption Price has not been paid. Upon the Company’s receipt of such notice, (x) the applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall immediately return this Note, or issue a new Note (in accordance with Section 18(d)) to the Holder representing such Conversion Amount to be redeemed and (z) the Conversion Price of this Note or such new Notes shall be adjusted to the lesser of (A) the Conversion Price as in effect on the date on which the applicable Redemption Notice is voided and (B) the lowest Closing Sale Price of the shares of Common Stock during the period beginning on and including the date on which the applicable Redemption Notice is

delivered to the Company and ending on and including the date on which the applicable Redemption Notice is voided.

(b) Redemption by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(a) or Section 5(b) (each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by facsimile a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including the date which is three (3) Business Days prior to the Company’s receipt of the Holder’s Redemption Notice and ending on and including the date which is three (3) Business Days after the Company’s receipt of the Holder’s Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven Business Day period.

(13) VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law and as expressly provided in this Note.
