Certain capitalized terms are defined in Section 29.

(1) MATURITY AND AMORTIZATION PAYMENTS.

(a) Payment on Maturity. On January 3, 2010 (the "Maturity Date"), the Holder shall surrender this Note to the Company and the Company shall pay to the Holder an amount in cash representing all outstanding Principal and accrued and unpaid Interest, and following receipt of such payment, the Holder shall mark this Note as "Cancelled" and shall surrender such cancelled Note to the Company by courier, registered mail, or other traceable means. Beginning on the first day of the eighteenth (18^th) calendar month following the calendar month in which the Original Date occurs, the Company may, upon thirty (30) calendar days prior

written notice to Holder and at the sole election of the Company, prepay this Note in whole or in part for a cash redemption price equal to One Hundred Five Percent (105%) of the the portion of the principal amount being redeemed plus all accrued and unpaid interest on the portion of the principal amount being redeemed, provided that following such notice the Holder may convert all or any part of the portion of the Note to be redeemed so long as the Company receives a duly executed Conversion Notice pursuant to Section 3 of this Note prior to the date on which prepayment is actually made.

(b) Amortization Payments. Beginning on July 31, 2008 and at the end of each month thereafter (each, an "Amortization Date") until there is no outstanding Principal of this Note, the Company shall redeem $[ ] [1/36th of the original Principal amount of this Note] of this Note (each, an "Amortization Redemption Amount"). If the Company is unable to redeem all Principal and Interest with respect to all Amortization Redemption Amounts on this Note and the Other Notes, 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 subject to payment of an Amortization Redemption Amount on such Amortization Date pursuant to this Note and the Other Notes.

(c) Payment of Amortization Redemption Amount. The Company shall pay the Amortization Redemption Amount in cash in accordance with the provisions of Section 12; provided, however, that if the Conditions to Amortization Conversion (as defined below) are satisfied or waived in writing by the Holder and the Company provides the Amortization Conversion Notice (as defined below), then the Company shall have the right to require the Holder to convert all or any such portion of the Amortization Redemption Amount designated in the Amortization Conversion Notice into fully paid, validly issued and nonassessable shares of Common Stock in accordance with the applicable provisions of Section 3(c)(i). The Company may exercise its right to require conversion under this Section 1(c) by delivering at least 20 Trading Days prior to such Amortization Date a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent that specifically describes the portion of the Amortization Redemption Amount for this Note and the Other Notes that will be paid in Common Stock (the "Amortization Conversion Notice" and the date all of the holders received such notice is referred to as the "Amortization Conversion Notice Date"). The Amortization Conversion Notice shall be irrevocable; provided; that if any of the Conditions to Amortization Conversion is not satisfied on the applicable Amortization Date or waived by the Holder, the Company will notwithstanding delivery of the Amortization Conversion Notice be required to pay the Amortization Redemption Amount in cash. The conversion price applicable to an Amortization Conversion (the "Amortization Price") that is being paid in Common Stock pursuant to this Section 1(c) shall be 90% of the Weighted Average Price of the Common Stock for the 20 consecutive Trading Days immediately preceding the Amortization Date. For purposes of this Section 1(c), "Conditions to Amortization Conversion" means the following conditions: (i) the Common Stock shall be traded on the Principal Market, the NASDAQ Gobal Market or NASDAQ Capital Market, or the American Stock Exchange on the applicable Amortization Date, (ii) on the Amortization Date, either (x) the Registration Statement or Registration Statements contemplated by the Registration

(2) INTEREST; INTEREST RATE. Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 365-day year and actual days elapsed and shall be payable in arrears on the first day of each Calendar Quarter and on the Maturity Date during the period beginning on the Issuance Date and ending on, and including, the Maturity Date (each, an "Interest Date") with the first Interest Date being April 1, 2008. Interest shall be payable on each Interest Date at the option of the Company (i) in cash at the rate of 8.00% per annum (the "Cash Interest Rate") or (ii) at the rate of 10.00% per annum (the "Note Interest Rate", and referred to sometimes herein as the "Interest Rate") in the form of an additional Convertible Subordinated Note in the form of this Note in the principal amount of such Interest. Prior to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Cash Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount in accordance with Section 3(b)(i). From and after the occurrence of an Event of Default, the Interest Rate shall be increased so that the Cash Interest Rate shall be twelve percent (12.00%) per annum and the Note Interest Rate per annum shall be fifteen percent (15%) per annum. 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 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. Notwithstanding the foregoing, the Company may not elect to pay interest at the Note Interest Rate and issue additional Convertible Subordinated Notes in the principal amount of such Interest unless either (i) the Registration Statement or Registration Statements contemplated by the Registration Rights Agreement shall be effective and available for the sale of all of the then-outstanding Registrable Securities, together with the Common Stock issuable upon conversion of such additional Convertible Subordinated Notes in accordance with the terms of the Registration Rights Agreement or (ii) all shares of Common Stock issuable upon conversion of the Notes shall be eligible for sale without restriction and without the need for registration under any applicable federal or state securities laws.

(3) CONVERSION OF NOTES. 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) in increments of at least $50,000 of Principal (or such lesser amount if such amount represents the remaining Principal amount) 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 up to the nearest whole share. The Company shall pay any and all 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 (as defined below) (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, plus (B) accrued and unpaid Interest with respect to such Principal.

(ii) "Conversion Price" means, as of any Conversion Date (as defined below) or other date of determination, and subject to adjustment as provided herein, $1.10.

(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 5:00 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 (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 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 Company's transfer agent (the "Transfer Agent"). On or before the second Business Day following the date of receipt of a Conversion Notice (the "Share Delivery Date"), the Company shall (X) 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 Depository Trust Company ("DTC") through its Deposit Withdrawal At Custodian system or (Y) if the Transfer Agent is not participating in 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 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 five 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 19(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.

(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 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 date which is five Business Days after the Conversion Date (a "Conversion Failure"), then (A) the Company shall pay liquidated damages to the Holder for each day of such Conversion Failure in an amount equal to 1.0% of the product of (I) 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 (II) 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 within three (3) Trading Days after the Company's receipt of the facsimile copy of a Conversion Notice the Company shall fail 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 such holder's conversion of any Conversion Amount, 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 five (5) Business 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 deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Stock 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 Bid Price on the Conversion Date.

(iii) Book-Entry. 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 Conversion 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 physical surrender and reissue of this Note. The Holder and the Company shall maintain records showing the Principal and Interest 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 24.

(d) Limitations on Conversions.

(i) Beneficial Ownership. Unless waived by the Holder upon no less than sixty one (61) days prior written notice to the Company, the Company shall not effect any conversion of this Note pursuant to Section 3(a) 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% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. Even if the Holder waives the limitation set forth in the preceding sentence, the Company shall in no event 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 Section 3(a), to the extent that after giving effect to such conversion, the Holder (together with the Holder's affiliates) would beneficially own in excess of 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentences, 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. 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-Q or Form 10-K, (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 two Business 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 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.

(ii) Principal Market Regulation. The Company shall not be obligated to issue any shares of Common Stock upon conversion of this Note if the issuance of such shares of Common Stock would exceed that number of shares of Common Stock that the Company may issue upon conversion 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 holders of the Notes representing at least a majority of the principal amounts of the Notes then outstanding. Until such approval or written opinion is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (the "Purchasers") shall be issued, upon conversion of Notes, 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 Issuance 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 Issuance 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) the Company's failure to pay to the Holder any amount of Principal or Interest when and as due under this Note if such failure continues for a period of at least five Business Days;

(ii) the Company's failure to pay to the Holder any amounts other than Principal or Interest when and as due under this Note, the Securities Purchase Agreement, or the Registration Rights Agreement, which failure is not cured within five Business Days after notice of such default sent by the Holder to the Company;

(iii) any default under, redemption of or acceleration prior to maturity of any Indebtedness (as defined below) of the Company or any of its Subsidiaries (as defined in the Securities Purchase Agreement) other than with respect to any Other Notes and the Senior Indebtedness; provided that in the case of a payment default of such Indebtedness, such default is not cured within applicable cure periods; further provided that in the case of a non-payment default of such Indebtedness that has not resulted in an acceleration or redemption of such Indebtedness prior to its maturity, only upon acceleration or redemption of such Indebtedness;

(iv) the Company shall fail to observe or perform any other material covenant or agreement contained in the Securities Purchase Agreement, which failure is not cured within ten Business Days after notice of such default sent by the Holder to the Company;

(v) the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal 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"), or (D) makes a general assignment for the benefit of its creditors;

(vi) 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 that remains undismissed for a period of 90 days, (B) appoints a Custodian of the Company or any of its Subsidiaries that remains undischarged or unstayed for a period of 90 days, or (C) orders the liquidation of the Company or any of its Subsidiaries;

(vii) 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 60 days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within 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;

(viii) any breach or failure to comply with Section 15 of this Note; or

(ix) any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes.

(b) Redemption Right. Promptly after the occurrence of an Event of Default with respect to this Note or any Other Note, the Company shall 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 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 redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the Conversion Amount to be redeemed and (ii) the product of (A) the Conversion Rate with respect to such Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice and (B) the Closing Sale Price of the Common Stock on the date immediately preceding such Event of Default (the "Event of Default Redemption Price"). Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 12.

(5) RIGHTS UPON CHANGE OF CONTROL.

(a) Change of Control. Each of the following events shall constitute a "Change of Control":

(i) the consolidation, merger or other business combination (including, without limitation, a reorganization or recapitalization) of the Company with or into another Person (other than (A) a consolidation, merger or other business combination (including, without limitation, reorganization or recapitalization) in which holders of the Company's voting power immediately prior to the transaction continue after the transaction to hold, directly or indirectly, the voting power of the surviving entity or entities necessary to elect a majority of the members of the board of directors (or their equivalent if other than a corporation) of such entity or entities, or (B) pursuant to a migratory merger effected solely for the purpose of changing the jurisdiction of incorporation of the Company);

(ii) the sale or transfer of all or substantially all of the Company's assets; or

(iii) a purchase, tender or exchange offer made to and accepted by the holders of more than the 50% of the outstanding shares of Common Stock.

No sooner than 15 days nor later than 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").

(b) Assumption. Prior to the consummation of any Change of Control, the Company will secure from any Person purchasing the Company's assets or Common Stock or any successor resulting from such Change of Control (in each case, an "Acquiring Entity") a written agreement (in form and substance satisfactory to the holders of Notes representing at least a majority of the aggregate principal amount of the Notes then outstanding) to deliver to each holder of Notes in exchange for such Notes, a security of the Acquiring 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 held by such holder, and satisfactory to the holders of Notes representing at least a majority of the principal amount of the Notes then outstanding. In the event that an Acquiring Entity is directly or indirectly controlled by a company or entity whose common stock or similar equity interest is listed, designated or quoted on a securities exchange or trading market, the holders of Notes representing at least a majority of the aggregate principal amount of the Notes then outstanding may elect to treat such Person as the Acquiring Entity for purposes of this Section 5(b).

(c) Redemption Right. At any time during the period beginning after the Holder's receipt of a Change of Control Notice and ending on the date of the consummation of such Change of Control (or, in the event a Change of Control Notice is not delivered at least 10 days prior to a Change of Control, at any time on or after the date which is 10 days prior to a Change of Control and ending ten days after 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") to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem; provided, however, that the Company shall not be under any obligation to redeem all or any portion of this Note or to deliver the applicable Change of Control Redemption Price unless and until the applicable Change of Control is consummated. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company in cash at a price equal to the greater of (i) the sum of (x) the product of (A) the Applicable Percentage (as defined below) and (B) the Conversion Amount being redeemed and (y) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed through the date of such redemption payment and (ii) the product of (x) the Applicable Percentage and (y) the sum of (1) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient determined by dividing (I) the aggregate cash consideration and the aggregate cash value of any non-cash consideration per Common Share to be paid to the holders of the

Common Shares upon consummation of the Change of Control (any such non-cash consideration in the form of securities to be valued at the higher of the Closing Sale Price of such securities as of the Trading Day immediately prior to the consummation of such Change of Control, the Closing Sale Price on the Trading Day immediately following the public announcement of such proposed Change of Control and the Closing Sale Price on the Trading Day immediately prior to the public announcement of such proposed Change of Control) by (II) the Conversion Price plus (2) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed through the date of such redemption payment, (the "Change of Control Redemption Price"). Redemptions required by this Section 5(c) 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. For purposes of this Note, the term "Applicable Percentage" means 120% if the Change of Control is consummated on or before the first (1^st) anniversary of the Original Date, 115% if the Change of Control is consummated after the first (1^st) anniversary of the Original Date but on or before the second (2^nd) anniversary of the Original Date, and 110% if the Change of Control is consummated at any time after the second (2^nd) anniversary of the Original Date.

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

(a) 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 before 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 Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(b) Other Corporate Events. Prior to the consummation of any recapitalization, reorganization, consolidation, merger, spin-off or other business combination (other than a Change of Control) pursuant to which holders of Common Stock are entitled to receive securities or other assets with respect to or in exchange for 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, (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 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 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 holders of Notes representing at least a majority of the aggregate principal amount of the Notes then outstanding.

(7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

(a) Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Issuance Date, the Company issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding shares of Common Stock deemed to have been issued or sold by the Company in connection with any Excluded Security) for a consideration per share (the "New Securities Issuance Price") less than a price (the "Applicable Price") equal to the Conversion Price in effect immediately prior to such issue or sale (the foregoing a "Dilutive Issuance"), then immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount (rounded to the nearest cent) equal to the New Securities Issuance Price. For purposes of determining the adjusted Conversion Price under this Section 7(a), the following shall be applicable:

(i) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 7(a)(i), the "lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion or exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange or exercise of such Convertible Securities.

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of

such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii), the "price per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible Security and upon the conversion or exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion Price shall be made by reason of such issue or sale. Notwithstanding anything in this Note to the contrary, in the event that the Company agrees to decrease the conversion price of any of its 7% Convertible Secured Promissory Notes due August 2007 in connection with an agreement by the holder of any such notes to convert the same, such decrease in the conversion price will not result in any adjustment to the Conversion Price pursuant to this Section 7(a) of this Note.

(iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold.

(iv) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Closing Sale Price of such securities on the date of receipt. If any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Stock,

Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the holders of Notes representing at least a majority of the principal amounts of the Notes then outstanding. If such parties are unable to reach agreement within ten days after the occurrence of an event requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined within five Business Days after the tenth day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the holders of Notes representing at least a majority of the principal amounts of the Notes then outstanding. The determination of such appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne equally by the Company, on the hand, and the holders of the Notes, on the other hand.

(v) Record Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

(b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time 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 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.

(c) 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.

(9) COMPANY'S RIGHT OF MANDATORY CONVERSION. (a) Mandatory Conversion. If at any time from and after the Issuance Date, the Weighted Average Price of the Common Stock exceeds 250% of the Conversion Price as of the Original Date (subject to appropriate adjustments for stock splits, stock dividends, stock combinations and other similar transactions after the Original Date) for each of any 20 consecutive Trading Days

(the "Mandatory Conversion Measuring Period") and the Conditions to Mandatory Conversion (as set forth in Section 9(c)) are satisfied or waived in writing by the Holder, the Company shall have the right to require the Holder to convert all or any such portion of the Conversion Amount of this Note designated in the Mandatory Conversion Notice into fully paid, validly issued and nonassessable shares of Common Stock in accordance with Section 3(c) hereof at the Conversion Rate as of the Mandatory Conversion Date (as defined below) (a "Mandatory Conversion"). The Company may exercise its right to require conversion under this Section 9(a) by delivering within not more than five Trading Days following the end of such Mandatory Conversion Measuring Period a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the "Mandatory Conversion Notice" and the date all of the holders received such notice is referred to as the "Mandatory Conversion Notice Date"). The Mandatory Conversion Notice shall be irrevocable.

(b) Pro Rata Conversion Requirement. If the Company elects to cause a conversion of all or any portion of the Conversion Amount of this Note pursuant to Section 9(a), then it must simultaneously take the same action with respect to the Other Notes (except that the Company is not required to take the same action with respect to the Other Notes to the extent limited by Section 3(d) in this Note or similar provisions under the Other Notes). If the Company elects to cause the conversion of this Note pursuant to Section 9(a) (or similar provisions under the Other Notes) with respect to less than all of the Conversion Amounts of the Notes then outstanding, then the Company shall require conversion of a Conversion Amount from each of the holders of the Notes equal to the product of (I) the aggregate Conversion Amount of Notes which the Company has elected to cause to be converted pursuant to Section 9(a), multiplied by (II) the fraction, the numerator of which is the sum of the aggregate principal amount of the Notes purchased by such holder pursuant to the Securities Purchase Agreement and the denominator of which is the sum of the aggregate principal amount of the Notes and purchased by all holders pursuant to the Securities Purchase Agreement (except to the extent limited by Section 3(d) in this Note or similar provisions under the Other Notes) (such fraction with respect to each holder is referred to as its "Allocation Percentage," and such amount with respect to each holder is referred to as its "Pro Rata Conversion Amount"). In the event that the initial holder of any Notes shall sell or otherwise transfer any of such holder's Notes, the transferee shall be allocated a pro rata portion of such holder's Allocation Percentage. The Mandatory Conversion Notice shall state (i) the Trading Day selected for the Mandatory Conversion in accordance with Section 9(a), which Trading Day shall be at least 10 Business Days but not more than 60 Business Days following the Mandatory Conversion Notice Date (the "Mandatory Conversion Date"), (ii) the aggregate Conversion Amount of the Notes which the Company has elected to be subject to mandatory conversion from all of the holders of the Notes pursuant to this Section 9 (and analogous provisions under the Other Notes), (iii) each holder's Pro Rata Conversion Amount of the Conversion Amount of the Notes the Company has elected to cause to be converted pursuant to this Section 9 (and analogous provisions under the Other Notes) and (iv) the number of shares of Common Stock to be issued to such Holder as of the Mandatory Conversion Date. All Conversion Amounts converted by the Holder after the Mandatory Conversion Notice Date shall reduce the Conversion Amount of this Note required to

be converted on the Mandatory Conversion Date. If the Company has elected a Mandatory Conversion, the mechanics of conversion set forth in Section 3(c) shall apply, to the extent applicable, as if the Company and the Transfer Agent had received from the Holder on the Mandatory Conversion Date a Conversion Notice with respect to the Conversion Amount being converted pursuant to the Mandatory Conversion.

(c) Conditions to Mandatory Conversion. For purposes of this Section 9, "Conditions to Mandatory Conversion" means the following conditions: (i) during the period beginning on the date that is six months prior to the Mandatory Conversion Date and ending on and including the Mandatory Conversion Date, the Company shall have delivered shares of Common Stock upon any conversion of Conversion Amounts as set forth in Section 3(c)(i); (ii) on each day during the period beginning on the first Trading Day of the Mandatory Conversion Measuring Period and ending on and including the Mandatory Conversion Date, the Common Stock shall be traded on the Principal Market, the NASDAQ Global Market or Global Select Market, the NASDAQ Capital Market, the New York Stock Exchange, or the American Stock Exchange; (iii) on the Mandatory Conversion Date either (x) the Registration Statement or Registration Statements contemplated by the Registration Rights Agreement shall be effective and available for the sale for all of the Registrable Securities in accordance with the terms of the Registration Rights Agreement or (y) all shares of Common Stock issuable upon conversion of the Notes shall be eligible for sale without restriction and without the need for registration under any applicable federal or state securities laws; (iv) on the Mandatory Conversion Date, an Authorized Share Failure shall not be in effect; and (v) any such payment of the Conversion Amount in Common Stock shall not consist of more than 20% of the total dollar volume traded in the Common Stock for the 20 Trading Days prior to the Mandatory Conversion Date.

(10) NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, 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 100% of the Conversion Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. Thereafter, the Company, so long as any of the Notes are outstanding, shall use commercially reasonable efforts to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 100% 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 (without regard to any limitations on conversions) (the "Required Reserve Amount"). The number of shares of Common Stock reserved for conversions of the Notes 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 time of Issuance Date 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 as soon as practicable use commercially reasonable efforts 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.

(12) HOLDER'S REDEMPTIONS.

(a) Mechanics. In the event that the Holder has sent an Event of Default Redemption Notice or a Change of Control Redemption Notice to the Company pursuant to Section 4(b) or Section 5(c), respectively (each, a "Redemption Notice"), the Holder shall promptly submit this Note to the Company. If the Holder has submitted an Event of Default Redemption Notice in accordance with Section 4(b), the Company shall deliver the applicable Event of Default Redemption Price to the Holder within five Business Days after the Company's receipt of the Holder's Event of Default Redemption Notice. If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(c), the Company shall deliver the applicable Change of Control Redemption Price to the Holder concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control and within five Business Days after the Company's receipt of such notice if such notice is received after the consummation of such Change of Control. With respect to an Amortization Redemption, the Company shall deliver the applicable Amortization Redemption Amount to the Holder within five Business Days after the end of the applicable month for such Amortization Redemption. 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, at the Holder's request, a new Note (in accordance with Section 19(d)) representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the Event of Default Redemption Price, the Change of Control Redemption Price, or the Amortization Redemption Amount (each, the "Redemption Price"), as applicable, to the Holder (or deliver any Common Stock to be issued pursuant to a Redemption Notice) within the time period required, at any time thereafter and until the Company pays such unpaid Redemption Price (and issues any Common Stock required pursuant to a Redemption Notice) 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 (or any Common Stock required to be issued pursuant to a Redemption Notice) has not been paid. Upon the Company's receipt of such notice, (x) the 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 19(d)) to the Holder representing such Conversion Amount 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 Redemption Notice is voided and (B) the Closing Bid Price on the date on which the 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(b) or Section 5(c) (each, an "Other Redemption Notice"), the Company shall immediately 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 Business Day period beginning on and including the date which is three Business Days prior to the Company's receipt of the Holder's Redemption Notice and ending on and including the date which is three 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 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) SUBORDINATION TO SENIOR INDEBTEDNESS.

(a) General. The Company and the Holder covenant and agree that this Note shall be subject to the provisions of this Section 13 and to the extent and in the manner set forth in this Section 13, the indebtedness represented by this Note and the payment of Principal, Interest, the Redemption Price, and any redemption amount, liquidated damages, fees, expenses, or any other amounts in respect of this Note are hereby expressly made subordinate and junior and subject in right of payment to the prior payment in full in cash of all Senior Indebtedness of the Company now outstanding or hereinafter incurred.

(b) No Payment if Default in other Senior Indebtedness.

(i) [Intentionally left blank]

(ii) No cash payment on account of Principal or Redemption Price of, or Interest on, this Note or any other payment payable with respect to this Note shall be made, and no portion of this Note shall be redeemed or purchased directly or indirectly by the Company, if at the time of such payment or purchase or immediately after giving effect thereto, (A) a default in the payment of principal, premium, if any, interest or other

obligations in respect of any Senior Indebtedness having either an outstanding principal balance or a commitment to lend greater than $500,000 ("Designated Senior Debt") occurs and is continuing (or, in the case of Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument evidencing such Senior Indebtedness) (a "Payment Default"), unless and until such Payment Default shall have been cured or waived or shall have ceased to exist or (B) the Company shall have received notice (a "Payment Blockage Notice") from the holder or holders of Designated Senior Debt that there exists under such Designated Senior Debt a default, which shall not have been cured or waived, permitting the holder or holders thereof to declare such Designated Senior Debt due and payable, but only for the period (the "Payment Blockage Period") commencing on the date of receipt of the Payment Blockage Notice and ending on the earlier of (a) the date such default shall have been cured or waived, or (b) the 180th day immediately following the Company's receipt of such Payment Blockage Notice. The Company shall resume payments on and distributions in respect of this Note, including any past scheduled payments of the principal of (and premium, if any) and interest on this Note to which the Holder would have been entitled but for the provisions of this Section 13(b)(ii) in the case of a Payment Default, within five (5) Business Days of the date upon which such Payment Default is cured or waived or ceases to exist (and if payment is made within such time period, any Event of Default with respect to such nonpayment shall be cured). In addition, notwithstanding clauses (A) and (B) of this subsection (ii), unless the holders of Designated Senior Debt shall have accelerated the maturity of such Designated Senior Debt or there is a Payment Default, the Company shall resume payments on this Note within (5) Business Days after the end of each Payment Blockage Period. In any consecutive 365-day period, there shall be (i) no more than three Payment Blockage Notices given in the aggregate on this Note and the Other Notes, irrespective of the number of defaults with respect to Designated Senior Debt during such period, and (ii) at least 90 days during which no Payment Blockage Period shall be in effect.

(c) Payment upon Dissolution, Etc. In the event of any bankruptcy, insolvency, reorganization, receivership, composition, assignment for benefit of creditors or other similar proceeding initiated by or against the Company or any dissolution or winding up or total or partial liquidation or reorganization of the Company (being hereinafter referred to as a "Proceeding"), the Holder agrees that such Holder shall, upon request of a holder of Senior Indebtedness, and at such holder of Senior Indebtedness' own expense, take all reasonable actions (including but not limited to the execution and filing of documents and the giving of testimony in any Proceeding, whether or not such testimony could have been compelled by process) necessary to prove the full amount of all its claims in any Proceeding, and the Holder shall not waive any claim in any Proceeding without the written consent of such holder. If the Holder does not file a proper proof of claim or proof of debt in the form required in any Proceeding at least thirty (30) days before the expiration of the time to file such claim, the holders of any Senior Indebtedness are hereby authorized to file an appropriate claim for and on behalf of the Holder.

The Holder shall retain the right to vote and otherwise act with respect to the claims under this Note (including, without limitation, the right to vote to accept or reject any plan of partial or complete liquidation, reorganization, arrangement, composition or extension); provided that the Holder shall not vote with respect to any such plan or take any other action in any way so as to (i) contest the validity of any Senior Indebtedness or any collateral therefor or guaranties thereof, (ii) contest the relative rights and duties of any of the lenders under the Senior Indebtedness established in any instruments or agreement creating or evidencing the Senior Indebtedness with respect to any of such collateral or guaranties, or (iii) contest the Holders' obligations and agreements set forth in this Section 13.

Upon payment or distribution to creditors in a Proceeding of assets of the Company of any kind or character, whether in cash, property or securities, all principal and interest due upon any Senior Indebtedness shall first be paid in full before the Holder shall be entitled to receive or, if received, to retain any payment or distribution on account of this Note, and upon any such Proceeding, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holder would be entitled except for the provisions of this Section 13 shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holder who shall have received such payment or distribution, directly to the holders of the Senior Indebtedness (pro rata to each such holder on the basis of the respective amounts of such Senior Indebtedness held by such holder) or their representatives to the extent necessary to pay all such Senior Indebtedness in full after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness, before any payment or distribution is made to the Holder or any holders of the Notes.

(d) Payments on Notes. Subject to Sections 13(b) and 13(c), the Company may make regularly scheduled payments of the Principal of, or Interest on, this Note or any other payment payable with respect to this Note, if at the time of payment, and immediately after giving effect thereto, there exists no Payment Default or a Payment Blockage Period.

(e) Certain Rights. Nothing contained in this Section 13 or elsewhere in this Note is intended to or shall impair, as among the Company, its creditors including the holders of Senior Indebtedness and the Holder, the right, which is absolute and unconditional, of the Holder to convert this Note in accordance herewith.

(f) Subrogation. Subject to payment in full in cash of all Senior Indebtedness, the rights of the Holder shall be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of the assets of the Company made on such Senior Indebtedness until all principal and interest on this Note shall be paid in full in cash; and for purposes of such subrogation, no payments or distributions to the holders of Senior Indebtedness of any cash, property or securities to which the Holder would be entitled except for the subordination provisions of this Section 13 shall, as between the Holder and the Company and/or its creditors other than the holders of the Senior Indebtedness, be deemed to be a payment on account of the Senior Indebtedness.

(g) Rights of Holders Unimpaired. The provisions of this Section 13 are and are intended solely for the purposes of defining the relative rights of the Holder and the holders of Senior Indebtedness and nothing in this Section 13 shall impair, as between the Company and the Holder, the obligation of the Company, which is unconditional and absolute, to pay to the Holder the principal thereof (and premium, if any) and interest thereon, in accordance with the terms of this Note.

(h) Holders of Senior Indebtedness. These provisions regarding subordination will constitute a continuing offer to all Persons who, in reliance upon such provisions, become holders of, or continue to hold, Senior Indebtedness; such provisions are made for the benefit of the holders of Senior Indebtedness, and such holders are hereby made obligees under such provisions to the same extent as if they were named therein, and they or any of them may proceed to enforce such subordination and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders have agreed in writing thereto. The holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Holder, without incurring responsibility to the Holder and without impairing or releasing the subordination provisions of this Section 13, (i) subject to the limitations set forth herein, increase the amount of, change the manner, terms or place of payment of, or renew or alter, any Senior Indebtedness, or otherwise amend, modify, restate or supplement the same (provided that any such modified indebtedness continues to be constitute Senior Indebedness within the meaning of this Agreement, (ii) sell, exchange or release any collateral mortgaged, pledged or otherwise securing the Senior Indebtedness, (iii) release any Person liable in any manner for the Senior Indebtedness and (iv) exercise or refrain from exercising any rights against the Company or any other Person.

(i) Proceeds Held in Trust. In the event that notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise) prohibited by the provisions hereof shall be received by the Holder before all Senior Indebtedness if paid in full in cash, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness, as their respective interests may appear, as calculated by the Company, for application to, or to be held as collateral for, the payment of any Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in cash after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness.

(j) Blockage of Remedies. During any Payment Default or any Payment Blockage Period, if an Event of Default has occurred and is continuing under this Note, the Holder will not commence or join with any creditor of the Company in asserting or commencing any proceedings to collect or enforce its rights hereunder or take any action to foreclose or realize upon the indebtedness hereunder for a period beginning on the date of such Event of Default and ending on the first to occur of (i) the date that is 180 days following the

date that the holders of the Senior Indebtedness are notified of such Event of Default or (ii) the date such Payment Default is cured, waived or ceases to exist or the date such Payment Blockage Period ends, as the case may be; provided, however, that until all of the Senior Indebtedness shall have been paid in full in cash, any payments, distributions or proceeds received by the Holder resulting from the exercise of any action to collect or enforce any right or remedy available to the Holder shall be subject to the terms of this Note.

(k) Subsequent Senior Indebtedness Requested Modifications. In connection with the incurrence of any future Senior Indebtedness, the Holder agrees that it shall act reasonably and negotiate in good faith any modifications to the provisions of this Section 13 reasonably requested by the holder of such Senior Indebtedness; provided that nothing in this section shall restrict the holders of Notes representing at least a majority of the aggregate principal amount of the Notes then outstanding from changing or amending this Section 13 pursuant to Section 17 hereof.

(l) Failure to Make Payment. In the event that the Company is prohibited or restricted from making any payment required under under this Note by reason of the provisions of this Section 13, such prohibition or restriction shall not preclude the failure to make such payment from being an Event of Default under Section 4(a) of this Note.

(14) VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law, including but not limited to the Delaware General Corporation Law, and as expressly provided in this Note.

(15) RANK; ADDITIONAL INDEBTEDNESS; LIENS.

(a) Rank. All payments due under this Note (a) shall rank pari passu with all Other Notes ("Pari Passu Indebtedness"), (b) shall be subordinate in right of payment to the prior payment of all existing and future Senior Indebtedness and (c) shall be senior to all other Indebtedness of the Company and its Subsidiaries, other than Senior Indebtedness and Pari Passu Indebtedness.

(b) Incurrence of Senior Indebtedness. So long as this Note is outstanding, the Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness which shall rank senior to the Notes other than Senior Indebtedness.

(c) Existence of Liens. So long as this Note is outstanding, the Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, allow or suffer to exist any mortgage, lien, pledge, charge, security interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by the Company or any of its Subsidiaries (collectively, "Liens") other than Permitted Liens. As used herein, "Permitted Liens" means (i) Liens incurred to secure Senior Indebtedness, (ii) Liens on fixed or capital assets acquired, constructed or improved by the Company or any

Subsidiary, to the extent of Indebtedness incurred within thirty days for such acquisition, construction or improvement and incurred within thirty days of such acquisition, construction or improvement, (iii) purchase money Liens, or (iv) carriers', warehousemen's, mechanics', materialmen's, repairmen's and other similar Liens imposed by law.

(d) Restricted Payments. The Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, redeem, defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole or in part, whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any Indebtedness, other than Senior Indebtedness or Pari Passu Indebtedness, whether by way of payment in respect of principal of (or premium, if any) or interest on, such Indebtedness if at the time such payment is due or is otherwise made or, after giving effect to such payment, an event constituting an Event of Default has occurred and is continuing.

(16) PARTICIPATION. The Holder, as the holder of this Note, shall be entitled to such dividends paid and distributions made to the holders of Common Stock (each, a "Distribution"), in each such case to the extent of the Distribution as if the Holder had converted this Note into Common Stock (without regard to any limitations on conversion herein or elsewhere) and had held such shares of Common Stock on the record date for such dividends and distributions. Payments (if any) under the preceding sentence shall be made concurrently with the dividend or distribution to the holders of Common Stock.

(17) VOTE TO ISSUE, OR CHANGE THE TERMS OF, NOTES. The affirmative vote at a meeting duly called for such purpose or the written consent without a meeting, of the holders of Notes representing not less than a majority of the aggregate principal amount of the then outstanding Notes, shall be required for any change or amendment to this Note or the Other Notes provided such change or amendment is consented to by the Company, which such consent may be granted or withheld in the sole discretion of the Company.

(18) TRANSFER. This Note may be offered, sold, assigned or transferred by the Holder without the consent of the Company, subject only to the provisions of Section 2(f) of the Securities Purchase Agreement.

(19) REISSUANCE OF THIS NOTE.

(a) Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section 19(d)), registered as the Holder may request, representing the outstanding Principal being transferred by the Holder and, if less then the entire outstanding Principal is being transferred, a new Note (in accordance with Section 19(d)) to the Holder representing the outstanding Principal not being transferred.
