This Senior Subordinated Convertible Note (including all Senior Subordinated Convertible Notes issued in exchange, transfer or replacement hereof, this “ Note ”) is one of an issue of Senior Subordinated Convertible Notes issued pursuant to the Securities Purchase Agreement (as defined below) on the Closing Date (collectively, the “ Notes ” and such other

Senior Subordinated Convertible Notes, the “ Other Notes ”). Certain capitalized terms used herein are defined in Section 29.

(1) PAYMENTS OF PRINCIPAL . On each Installment 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. The “ Maturity Date ” shall be December 20, 2009, 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 or any event shall have occurred and be continuing which with the passage of time and the failure to cure would result in an Event of Default, (ii) through the date that is ten (10) 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 and (iii) in accordance with Section 8(d).

(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 for each Payment Quarter on the first day of the succeeding Payment Quarter 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, 2006. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, and to the extent that any Principal amount of this Note is converted prior to such Interest Date, accrued and unpaid Interest with respect to such converted Principal amount and accrued and unpaid Late Charges with respect to such Principal and Interest shall be paid through the Conversion Date (as defined below) on the next succeeding Interest Date to the record holder of this Note on the applicable Conversion Date, in cash (“ Cash Interest ”) or, at the option of the Company, in shares of Common Stock (“ Interest Shares ”) or a combination thereof, provided that the Interest which accrued during any period may be payable in Interest Shares if, and only if, the Company delivers written notice (each, an “ Interest Election Notice ”) of such election to each holder of the Notes on or prior to the sixth (6 ^th ) Trading Day prior to the Interest Date (each, an “ Interest Notice Due Date ”). Each Interest Election Notice must specify the amount of Interest that shall be paid as Cash Interest, if any, and the amount of Interest that shall be paid in Interest Shares. 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 (a) the amount of Interest payable on such Interest Date less any Cash Interest paid divided by (b) the Interest Conversion Price in effect on the applicable Interest Date. If any Interest Shares are to be paid on an Interest Date, then the Company shall (X) provided that the Company’s transfer agent (the “ Transfer Agent ”) is participating in the Depository Trust Company (“ DTC ”) Fast Automated Securities Transfer Program and such action is not prohibited by applicable law or regulation or any applicable policy of DTC, 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 Agent Commission system, or (Y) if the foregoing shall not apply, issue and deliver on the applicable Interest Date, 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 three 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

- 2 -

the Holder shall be entitled. Notwithstanding the foregoing, the Company shall not be entitled to pay Interest in Interest Shares and shall be required to pay such Interest in cash as Cash Interest on the applicable Interest Date if, unless consented to in writing by the Holder, during the period commencing on the applicable Interest Notice Due Date through the applicable Interest Date the Equity Conditions have not been satisfied. Prior to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate. Upon the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to ten percent (10%). 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 transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Interest Shares; provided that the Company shall not be required to pay any tax that may be payable in respect of any issuance of Interest Shares to any Person other than the Holder.

(3) CONVERSION OF NOTES . This Note shall be convertible into shares of the Company’s common stock, par value $0.10 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 up 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 portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made.

(ii) “ Conversion Price ” means, as of any Conversion Date (as defined below) or other date of determination, $19.00, subject to adjustment as provided herein.

(c) Mechanics of Conversion .

(i) Optional Conversion . To convert any Conversion Amount into shares of Common Stock on any date (a “ Conversion Date ”), the Holder shall (A) transmit

- 3 -

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 (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 second (2nd) 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 Business 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 Agent Commission 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 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 (5) 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. Subject to compliance with relevant transfer restrictions, 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. In the event of a partial conversion of this Note pursuant hereto, the principal amount converted shall be deducted from the Installment Amounts relating to the Installment Dates as set forth in the Conversion Notice.

(ii) Company’s Failure to Timely Convert . 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 (a “ Conversion Failure ”), 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) Business Days after the Holder’s request and in the Holder’s discretion and after delivery by such Holder to the Company of evidence reasonably satisfactory to the Company and not unreasonably burdensome to the Holder of such purchase and sale by such Holder, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, 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 reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal, Interest and Late Charges converted and the dates of such conversions or shall use such other reasonably satisfactory method so as not to require physical surrender of this Note upon conversion. Notwithstanding anything in this Note to the contrary, the Company shall be entitled to treat the registered holder of this Note as such appears in its records, as the owner of this Note for all purposes; provided that such records are kept current using a reasonably satisfactory and customary method intended for such purpose.

(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 . 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 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% (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 “ 1934 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-Q or Form 8-K, as the case may be (y) a more recent public announcement by

- 5 -

the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock 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. For purposes hereof, the Company may rely on the representations of the Buyer set forth on the applicable Conversion Notices. 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 (61 ^st ) 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.

(ii) Principal Market Regulation . At all times, irrespective of whether the Company is listed on the Principal Market, 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 the aggregate number of shares of Common Stock which the Company may issue upon conversion or exercise or otherwise, as applicable, of the Notes and Warrants without breaching the rules or regulations of the Principal Market as if the Company were regulated by such rules or regulations (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 or exercise or otherwise, as applicable, of Notes or Warrants, 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 the Purchasers 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, if a registered Holder of such Notes, 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 registered holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder. To the extent required by the Principal Market, the provisions of the Exchange Cap shall be modified to comply with the applicable rules and regulations of the Principal Market, provided that any such changes shall not, in the Holder’s reasonable discretion, materially change the terms of the transaction contemplated hereby.

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) purchasable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or its equivalent) of the Successor Entity, 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.

- 9 -

consummation of the Change of Control 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. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the Company at a price equal to the greater of (i) the product of (x) the Change of Control Premium of the sum of the Conversion Amount being redeemed together with accrued and unpaid Interest with respect to such Conversion Amount and accrued and unpaid Late Charges with respect to such Conversion Amount and Interest and (y) the quotient determined by dividing (A) the Closing Sale Price of the Common Stock immediately following the public announcement of such proposed Change of Control by (B) the Conversion Price and (ii) the Change of Control Premium of the sum of the Conversion Amount being redeemed together with accrued and unpaid Interest with respect to such Conversion Amount and accrued and unpaid Late Charges with respect to such Conversion Amount and Interest (the “ Change of Control Redemption Price ”). Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 13 and shall have priority to payments to stockholders in connection with a Change of Control. 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(c) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3.

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

(a) Purchase Rights . If at any time (the “ Purchase Right Date ”) 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. Notwithstanding any provision of this Section 6(a) to the contrary, in the event that the Weighted Average Price of the Common Stock equals or exceeds 150% of the applicable Conversion Price for each of the twenty (20) consecutive Trading Days immediately preceding a Purchase Right Date, then this Section 6(a) shall not apply to such Purchase Right.

(b) 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, (i) in addition to the shares of Common Stock receivable upon

- 10 -

such conversion, if applicable, 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. 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 Issuance of Common Stock . If at any time after the Subscription 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 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 product of (A) the Conversion Price in effect immediately prior to such Dilutive Issuance and (B) the quotient determined by dividing (1) the sum of (I) the product derived by multiplying the Conversion Price in effect immediately prior to such Dilutive Issuance and the number of shares of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any, received by the Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Conversion Price in effect immediately prior to such Dilutive Issuance by (II) the number of shares of Common Stock Deemed Outstanding immediately after such Dilutive Issuance. 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,

- 11 -

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.

(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. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the Subscription Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

(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

- 12 -

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 Required Holders. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “ Valuation Event ”), the fair value of such consideration will be determined within five (5) Business Days after the tenth (10 ^th ) day following the Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Required Holders. 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 by the Company.

(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 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 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.

(8) COMPANY INSTALLMENT CONVERSION OR REDEMPTION .

(a) General . On each applicable Installment Date, the Company shall pay to the Holder of this Note the Installment Amount as of such Installment Date by the combination of any of the following, but subject to and in accordance with the terms of this Section 8, (i) provided that during the period commencing with the Company Installment Notice (as defined below) through the applicable Installment Date, the Equity Conditions have been

- 13 -

satisfied (or waived in writing by the Holder), requiring the conversion of a portion of the applicable Installment Amount, in whole or in part, in accordance with this Section 8 (a “ Company Conversion ”), and/or (ii) redeeming the applicable Installment Amount, in whole or in part, in accordance with this Section 8 (a “ Company Redemption ”); provided that all of the outstanding applicable Installment Amount as of each such Installment Date must be converted and/or redeemed by the Company on the applicable Installment Date, subject to the provisions of this Section 8. Notwithstanding the foregoing, the Company may not effect a Company Conversion under this Section (i) in excess of 10% of the aggregate dollar trading volume (as reported on Bloomberg) of the Common Stock on the Principal Market over the forty (40) consecutive Trading Day period prior to the applicable Installment Notice Due Date or (ii) so long as the approval of the stockholder’s of the Company has not been obtained for the issuance of the shares relating to the Notes, including Interest Shares, and the Warrants in accordance with the rules of the Principal Market, if the issuance of the shares of Common Stock pursuant to such Company Conversion would cause the Maximum Installment Share Number to be exceeded. On or prior to the date which is the tenth (10 ^th ) Trading Day prior to each Installment Date (each, an “ Installment Notice Due Date ”), the Company shall deliver written notice (each, a “ Company Installment Notice ”), to the Holder which Company Installment Notice shall state (i) the portion, if any, of the applicable Installment Amount which the Company elects to convert pursuant to a Company Conversion, which amount when added to the Company Redemption Amount must equal the applicable Installment Amount (the “ Company Conversion Amount ”), (ii) the portion, if any, of the applicable Installment Amount which the Company elects to redeem pursuant to a Company Redemption (the “ Company Redemption Amount ”), which amount when added to the Company Conversion Amount must equal the applicable Installment Amount and (iii) if the Company has elected, in whole or in part, a Company Conversion, then the Company Installment Notice shall certify that the Equity Conditions have been satisfied as of the date of the Company Installment Notice. 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 electing a Company Conversion and shall be deemed to have certified that the Equity Conditions in connection with any such conversion have been satisfied. Except as expressly provided in this Section 8(a), the Company shall redeem and convert 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 redeemed and converted hereunder. The Company Redemption Amount shall be redeemed in accordance with Section 8(b) and 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(c).

(b) Mechanics of Company Redemption . If the Company elects a Company Redemption in accordance with Section 8(a), then the Company Redemption Amount, if any, which is to be paid to the Holder on the applicable Installment Date shall be redeemed by the Company on such Installment Date, 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,

- 14 -

“ Conversion Notice ” for purposes of this Note), the Holder may require the Company to convert all or any part of the Company Redemption Amount at the Company Conversion Price. Conversions required by this Section 8(b) shall be made in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(b), 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 Installment Amounts relating to the applicable Installment Dates as set forth in the applicable Conversion Notice.

(c) Mechanics of Company Conversion . Subject to Section 3(d), if the Company delivers a Company Installment Notice and elects, or is de
