AMENDED AND RESTATED SENIOR SECURED CONVERTIBLE NOTE

	
  Issuance   Date:  March 21, 2005
  	
  
Principal: U.S. $_____________
  

          FOR VALUE RECEIVED, Verilink Corporation, a Delaware corporation (the “Company”), hereby promises to pay to the order of _________________ or registered assigns (“Holder”) the amount set out above as the Principal (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined below), on any Installment Date with respect to the Installment Amount due on such Installment Date (each, as defined herein), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the rate of 9.00% per annum (the “Interest Rate”), from the date set out above as the Issuance Date (the “Issuance Date”) until the same becomes
due and payable, whether upon an Interest Date (as defined below), any Installment Date or the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof).  This Amended and Restated Senior Secured Convertible Note (including all Senior Secured Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”) amends, supplements, modifies and completely restates the Senior Secured Convertible Note,

dated as of March 21, 2005 (the “Existing Note”), issued by the Company to the order of the Holder in the maximum principal amount of $[____], but shall not, except as specifically amended hereby or as set forth in the Exchange Agreements (as defined below), constitute a release, satisfaction or novation of any of the obligations under the Existing Note or any other Transaction Document (as defined in the Securities Purchase Agreement, defined below).  This Note is one of an issue of Amended and Restated Senior Secured Convertible Notes issued pursuant to a series of Consent, Amendment and Exchange Agreements (the “Exchange Agreements”) dated as of March 9, 2006 (collectively, the “Notes” and such other Senior Secured 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 March 21, 2008, as the same may be extended at the option of the Holder (i) through the date that is fifteen (15) Business Days (or, in the case of the Event of Default specified in Section 4(a)(ix), sixty-five (65) days) after the cure or termination of any Event of Default (as defined in Section 4(a)) that has occurred and is continuing on the Maturity Date (as may be extended pursuant to this Section 1) or the termination of any event that has occurred and is continuing on the Maturity Date (as may be extended pursuant to this Section 1) and that with the passage of time and the
failure to cure would result in an Event of Default and (ii) through the date that is ten (10) 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.

          (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 Calendar Quarter on the tenth day of the succeeding Calendar 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 July 10, 2005.  Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest 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 twentieth (20th) Trading Day prior to
the Interest Date (each, an “Interest Notice Due Date”);
provided, further, that from and after November 21, 2005, the Company must pay
at least 50% of all Interest due hereunder as Cash Interest, unless at such time
the Stockholder Approval (as defined in the Securities Purchase Agreement) has
been obtained.  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 and (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 

- 2 -

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 two Business Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled.  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 and be payable by way of inclusion of the Interest in the Conversion Amount in accordance with Section 3(b)(i).  Upon the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to twelve percent (12%).  In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall
continue to apply to the extent relating to the days after the occurrence of such Event of Default through and including the date of cure of such Event of Default.  The Company shall pay any and all taxes that may be payable with respect to the issuance and delivery of Interest Shares; 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 or with respect to any income tax due by the Holder with respect to such Interest Shares.

          (3)          CONVERSION OF NOTES.  This Note shall be convertible into shares of the Company’s common stock, par value $.01 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 conversion would result in the issuance of a fraction of a share of Common Stock, unless the entire balance of the Note is being converted, the portion of the Conversion Amount that corresponds to such fraction of a share of Common Stock shall resume the status of unpaid
Principal on the Note.  If the entire balance of the Note is being converted, 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; provided that the Company shall not be required to pay any tax that may be payable in respect of any issuance of Common Stock to any Person other than the converting Holder or with respect to any income tax due by the Holder with respect to such Common Stock.

- 3 -

                         (b)          Conversion Rate.  The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

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

                                        (ii)         “Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination, $0.7826, subject to adjustment as provided herein.  

                                        (iii)        “Interim Conversion Price” means the lower of (A) the Conversion Price, (B) 92% of the Weighted Average Price of the Common Stock for each of the five (5) consecutive Trading Days ending on the Trading Day immediately preceding the date of the applicable Conversion Notice (as defined below) (as appropriately adjusted for any stock split, stock dividend, stock combination or other similar transaction during such period) and (C) 96% of the Weighted Average Price of the Common Stock for the Trading Day immediately preceding the date of the applicable Conversion Notice; provided, however, that in no event shall the Interim Conversion Price be less than $0.5217 (as
appropriately adjusted for any stock split, stock dividend, stock combination or other similar transaction) (the “Interim Conversion Floor Price”).

                         (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 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)(iv), surrender this Note to a common carrier for delivery to the Company as soon as practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its
loss, theft or destruction).  On or before the first (1st) Business Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Transfer Agent.  On or before the second 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 and such action is not prohibited by applicable law or regulation or any applicable policy of DTC, 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 foregoing shall not apply, 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)(iv) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense,

- 4 -

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.  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)         (A) Required Interim Conversions.  So long as this Note is outstanding, during each Interim Conversion Period, the Holder shall convert a portion of this Note into a number of fully paid, validly issued and nonassessable shares of Common Stock equal to the Minimum Interim Amount (a “Required Interim Conversion”) by delivering one or more Conversion Notices indicating the applicable Interim Conversion Price being used.  Notwithstanding the foregoing, the Holder shall not be obligated to effect any Required Interim Conversion hereunder unless the Equity Conditions shall have been satisfied (or waived in writing by the Holder) during
each day of the applicable Interim Conversion Period.  Required Interim Conversions made pursuant to this Section 3(c)(ii)(A) shall be made in accordance with Section 3(c)(i) hereof; provided, however, that in the event that as of the end of any Interim Conversion Period the Holder has failed to effect the Required Interim Conversion in an amount equal to the Minimum Interim Amount and the Equity Conditions have been satisfied (or waived in writing by the Holder) during such Interim Conversion Period, then the Company may elect to, without delivery of a Conversion Notice or any action on the part of the Holder, cause a portion of this Note to be converted into a number of shares that, when added to the number of shares previously issued to the Holder upon conversion during such Interim Conversion Period, equals the Minimum Interim Amount by delivering written notice to the Holder of such election within five (5) Trading Days of the end of such Interim Conversion Period.

                                                     (B) Optional
Interim Conversions.  During any Interim Conversion Period, the Holder
may from time to time convert a portion of this Note (an “Optional
Interim Conversion Amount”) into a number of fully paid, validly issued
and nonassessable shares of Common Stock that does not exceed the Maximum
Interim Amount for such Interim Conversion Period (an “Optional Interim
Conversion”) by delivering one or more Conversion Notices indicating
the applicable Interim Conversion Price being used provided that the aggregate
number of shares of Common Stock issued during any Interim Conversion Period
shall not exceed the applicable Maximum Interim Amount. Optional Interim
Conversions made pursuant to this Section 3(c)(ii)(B) shall be made in
accordance with Section 3(c)(i) hereof.

                                        (iii)       Company’s Failure to Timely Convert.  If the Company shall fail, other than pursuant to Section 3(d), 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 damages in cash to the Holder for each date of such Conversion Failure in an amount equal to 2.0%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 

- 5 -

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)(iii) 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 three (3) 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, 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.

                                        (iv)       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
method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

                                        (v)        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.  The failure to issue to the Holder the number of shares of Common Stock in dispute shall not be a Conversion Failure.

- 6 -

                         (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.  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 the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.  For any reason at any time, upon the written or oral request of the Holder, the Company shall within one Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported.  By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified
in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes.

                                        (ii)        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 the aggregate number of shares of Common Stock which the Company may issue upon conversion or exercise, as applicable, of the Notes and Warrants and the payment of Interest in Interest Shares without breaching the Company’s obligations under the rules or regulations of the Nasdaq National Market or The Nasdaq Capital Market, as applicable (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 Nasdaq National Market or The Nasdaq Capital Market, as the case may be, 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 or any Exchange Agreement (the “Purchasers”) shall be issued in the aggregate, upon conversion or exercise, as applicable, of Notes or Warrants or the payment of Interest in Interest Shares, shares of Common Stock (as adjusted for stock splits, stock dividends, stock combinations and other similar transactions) in 

- 7 -

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 Exchange Agreements on the Exchange Closing Date and 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 Exchange Agreements on the Exchange Closing Date and the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”).  In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee.  In the event
that any holder of Notes shall convert all of such holder’s Notes into a number of shares of Common Stock which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in proportion to the aggregate principal amount of the Notes then held by each such holder.

          (4)          RIGHTS UPON EVENT OF DEFAULT.

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

                                        (i)          the failure of the applicable Registration Statement required to be filed pursuant to the Registration Rights Agreement to be declared effective by the SEC on or prior to the date that is sixty (60) days after the applicable Effectiveness Deadline (as defined in the Registration Rights Agreement), or, while the applicable Registration Statement is required to be maintained effective pursuant to the terms of the Registration Rights Agreement, the effectiveness of the applicable Registration Statement lapses for any reason (including, without limitation, the issuance of a stop order) or is unavailable to any holder of the Notes for sale of all of such holder’s
Registrable Securities (as defined in the Registration Rights Agreement) in accordance with the terms of the Registration Rights Agreement, and such lapse or unavailability continues for a period of ten (10) consecutive days or for more than an aggregate of thirty (30) days in any 365-day period (other than days during an Allowable Grace Period (as defined in the Registration Rights Agreement));

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

                                        (vi)       (A) any payment default or other default occurs under any Indebtedness (as defined in Section 3(s) of the Securities Purchase Agreement) of the Company or any of its Subsidiaries (as defined in Section 3(a) of the Securities Purchase Agreement) (other than the XEL Notes) that results in a redemption of or acceleration prior to maturity of $250,000 or more of such Indebtedness in the aggregate, (B) any payment default or other default occurs under the XEL Notes that results in a redemption of or acceleration of such notes or (C) any material default occurs under any Indebtedness of the Company (other than the XEL Notes) or any of its Subsidiaries having an aggregate outstanding

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

satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment;

- 9 -

                                        (x)     the Company breaches in any material respect any representation, warranty, covenant or other term or condition of any Transaction Document, except, in the case of a breach of a covenant or other term or condition of any Transaction Document which is curable, only if such breach continues for a period of at least ten (10) consecutive Business Days;

                                        (xi)    any breach or failure in any respect to comply with Section 15 of this Note or Section 8(b) of the Securities Purchase Agreement; or

                         (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 and prior to sixty (60) days after written notice from the Company to the Holder that such Event of Default is cured (which written notice shall provide satisfactory evidence that such Event of Default has actually been cured), 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 product of (x) the Conversion Amount to be redeemed and (y) the Redemption Premium 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 13.  In the event of a partial redemption of this Note pursuant hereto, the principal amount redeemed
shall be deducted from the Installment Amounts relating to the applicable Installment Dates as set forth in the Event of Default Redemption Notice.

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

                         (a)          Assumption.  The Company shall not enter into or be party to a Fundamental Transaction unless (i)  the Successor Entity (if other than the Company) assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by 

- 10 -

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 having similar ranking to the Notes, and satisfactory to the Required Holders and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market.  Upon the occurrence of any Fundamental Transaction, the Successor Entity (if other than the Company) 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 (if other than the Company) 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 stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had this Note been converted immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this Note.  The provisions of this Section shall apply similarly and equally to
successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion or redemption of this Note.

                         (b)          Redemption Right.  No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Change of Control Notice”).  At any time during the period beginning 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 ten (10) days prior to a Change of Control, at any time on or after the date which is ten (10) days prior to a Change of Control and ending ten (10)
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.  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 Conversion Amount being redeemed 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) 105% of the Conversion Amount being redeemed from the Issuance Date until six months from the Issuance Date, 110% of the Conversion Amount being redeemed from the end of such six month period until the first anniversary of the Issuance Date,
and 120% of the Conversion Amount being redeemed thereafter (the “Change of Control Redemption Price”).  Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 13 only if such Change of Control is consummated and shall have priority to payments to stockholders in connection with a Change of Control.  Notwithstanding anything to the contrary 

- 11 -

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.  In the event of a partial redemption of this Note pursuant hereto, the principal amount redeemed shall be deducted from the Installment Amounts relating to the applicable Installment Dates as set forth in the Change of Control Redemption Notice.

          (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”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, 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 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.  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, as applicable, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been
held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate.  Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders.  The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this
Note.

          (7)          RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

                         (a)          Adjustment of Conversion Price upon Issuance of Common Stock.  If and whenever on or 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 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 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.  Notwithstanding the foregoing, if the Company issues or sells any shares of Common Stock, Options or Convertible Securities as payment of, or in exchange for, the XEL
Notes, then immediately after such Dilutive Issuance the Conversion Price then in effect shall be reduced to an amount equal to the New 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 exercise of such Option and 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 or 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) 

- 13 -

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 pursuant to this Section 7(a)(iii) 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 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 marketable 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 shareholders 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 net assets and business of the non-surviving entity, calculated on a going concern basis, 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 (10th) 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 one-half by the Company and one-half by the Holders.  The consideration received by the Company need not be calculated for shares of Common Stock that are issued or sold or deemed issued or sold to the extent they constitute Excluded Securities.

- 14 -

                                        (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.

                         (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.

          (8)          INSTALLMENT AMOUNTS.  

                         (a)          General.  On each applicable Installment Date, the Company shall pay to the Holder of this Note the Installment Amount due as of such Installment Date.  The Installment Amount shall be payable by the Company in cash on the applicable Installment Date by wire transfer of immediately available funds.  Notwithstanding anything to the contrary in this Section 8(A), but subject to Section 3(d), until the applicable Installment Amount (together with any interest thereon) is paid in full, the Installment 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 Installment Amount prior to
the applicable Installment Date as set forth in the immediately preceding sentence, such Installment Amount so converted shall be deducted from the Installment Amount to be paid on such Installment Date.

- 15 -

                         (b)          Special Installment Amounts.  The Company shall announce its operating results (the “Operating Results”) for each Fiscal Quarter no later than the thirtieth (30th) day after the end of each Fiscal Quarter (or if such day is not a Trading Day, the next Trading Day) and such announcement shall include the amount of the Company’s Tested Working Capital.  In addition, if at the end of the Fiscal Quarter the Company’s Tested Working Capital is less than the Target Working Capital (a “Working Capital Deficiency”), the Company shall make publicly available (as part of the Operating Results announcement or, contemporaneously, on a Current Report on Form 8-K or otherwise) the fact that the
Company’s obligation to pay Special Installment Amounts has been triggered.  On the date of such announcement (the “Announcement Date”), the Company shall also provide to the Holders a certification (a “Working Capital Certification”) as to the amount of the Tested Working Capital as of the end of the Fiscal Quarter to which such Operating Results relate.  If at the end of any Fiscal Quarter a Working Capital Deficiency exists, the Company shall, on the Announcement Date, also provide to the Holder a notice (each such notice, a “Working Capital Deficiency Notice”) stating the amount of such Working Capital Deficiency.  At any time during the period beginning after the Holder’s receipt of a Working Capital Deficiency Notice (or, in the event that the Company does not deliver such Working Capital Deficiency Notice, at any time designated by the Holder) and ending seven (7) Business Days thereafter (the “Special
Installment Notice Due Date”), the Holder may require the Company to pay, on each Special Installment Date, a Special Installment Amount in accordance with the provisions of Section 8(a) by delivering written notice thereof (a “Special Installment Notice”) to the Company which Special Installment Notice shall state the Special Installment Amount due on the applicable Special Installment Date.  

          (9)          COMPANY’S RIGHT OF MANDATORY CONVERSION.

                         (a)          Mandatory Conversion.  If at any time from and after the one-year anniversary of the Effective Date (as defined in the Registration Rights Agreement) (the “Mandatory Conversion Eligibility Date”), (i) the Weighted Average Price of the Common Stock equals or exceeds 200% of the Conversion Price (subject to appropriate adjustments for stock splits, stock dividends, stock combinations and other similar transactions after the Subscription Date) for each of any twenty (20) consecutive Trading Days following the Mandatory Conversion Eligibility Date (the “Mandatory Conversion Measuring Period”) and (ii) the Equity Conditions shall have been satisfied (or waived in writing by the Holder, provided that the Holder may
not waive the provisions of Section 3(d)(ii)), during the period commencing on the Mandatory Conversion Notice Date through the applicable Mandatory Conversion Date (each, as defined below), the Company shall have the right to require the Holder to convert all, but not less than all, of the Conversion Amount then remaining under this Note plus the Present Value of Interest as designated in the Mandatory Conversion Notice (as defined below) 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”) or, at the Company’s option and solely with respect to the Present Value of Interest, cash or a combination of Common Stock and cash.  The Company may exercise its right to require conversion under this Section 9(a), by delivering within not more than two (2) 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 by facsimile is referred to as the “Mandatory Conversion Notice Date”).  The Mandatory Conversion Notice shall be irrevocable.  The Mandatory Conversion Notice shall state (i) the Trading Day selected for the Mandatory Conversion in

- 16 -

accordance with Section 9(a), which Trading Day shall be at least twenty (20) Business Days but not more than sixty (60) Business Days following the Mandatory Conversion Notice Date (the “Mandatory Conversion Date”), (ii) the aggregate Conversion Amount of the Notes 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) the number of shares of Common Stock to be issued to, and the Present Value of Interest to be paid to, such Holder on the Mandatory Conversion Date and (iv) the portion, if any, of the Present Value of Interest that shall be paid in cash and the portion, if any, that shall be paid in Common Stock.

                         (b)          Pro Rata Conversion Requirement.  If the Company elects to cause a conversion of any Conversion Amount of this Note pursuant to Section 9(a), then it must simultaneously take the same action in the same proportion with respect to the Other Notes.  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.

                         (9A)       COMPANY’S RIGHT OF OPTIONAL REDEMPTION.  At any time prior to the Maturity Date, provided that all Equity Conditions are satisfied between the Optional Redemption Notice Date and the Optional Redemption Date (each as hereinafter defined), the Company shall have the right to redeem all, but not less than all, of the Conversion Amount then remaining under this Note and the Other Notes (an “Optional Redemption”).  The Conversion Amount subject to redemption pursuant to this Section 9A shall be redeemed by the Company in cash at a price equal to 105% of the Conversion Amount (the “Optional Redemption Price”).  The Company may exercise its redemption right under this Section 9A by delivering a written notice thereof
by confirmed facsimile and overnight courier to all, but not less than all, of the holders of Notes (the “Optional Redemption Notice” and the date all of the holders received such notice is referred to as the “Optional Redemption Notice Date”).  The Optional Redemption Notice shall be irrevocable.  The Optional Redemption Notice shall state (A) the date on which the Optional Redemption shall occur (the “Optional Redemption Date”) which date shall be thirty (30) days after the Optional Redemption Notice Date and (B) the aggregate outstanding Principal amount of this Note (the “Optional Redemption Amount”) and the Other Notes which the Company shall redeem pursuant to this Section 9A on the Optional Redemption Date.  Notwithstanding anything to the contrary in this Section 9A, until the Optional Redemption Price is paid in full, the Optional Redemption Amount may be converted, in whole or in part, by the Holders into
shares of Common Stock in accordance with Section 3.  All Conversion Amounts converted by the Holder after the Optional Redemption Notice Date shall reduce the Optional Redemption Amount of this Note required to be redeemed on the Optional Redemption Date.  Redemptions made pursuant to this Section 9A shall be made in accordance with Section 13 to the extent applicable.

          (10)          SECURITY.  This Note and the Other Notes are secured to the extent and in the manner set forth in the Security Documents (as defined in the Securities Purchase Agreement).

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

          (12)          RESERVATION OF AUTHORIZED SHARES.

                          (a)          Reservation.  The Company shall initially reserve out of its authorized and unissued Common Stock at least 8,144,109 shares of Common Stock for all of the Notes.  So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 150% 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 pursuant to Sections 2 and 3 (without regard to any limitations on conversions) (the “Required Reserve Amount”).  The amount required to be reserved shall be reduced by the
number of shares of Common Stock issued upon conversion of the Notes.  The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the principal amount of the Notes held by each holder at the Closing (as defined in the Securities Purchase Agreement) or increase in the number of reserved shares, as the case may be (the “Authorized Share Allocation”).  In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation.  Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders.

                          (b)          Insufficient Authorized Shares.  If at any time while any of the Notes remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Notes then outstanding.  Without limiting the generality of the foregoing sentence, as soon as practicable after the date
of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock.  In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its reasonable best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.

          (13)          HOLDER’S REDEMPTIONS.

                          (a)          Mechanics.  The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five (5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice.  If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company shall deliver the applicable Change of Control Redemption Price to the Holder by the later of (i) consummation of the Change of Control or (ii) five (5) Business Days after the Company’s receipt of such notice.  The Company shall deliver the applicable Company Installment Redemption Price to the Holder on the applicable Installment Date and the applicable Optional Redemption Price to the Holder
on the applicable Optional Redemption Date.  In the event of a redemption of less than all of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 19(d)) representing the outstanding Principal which has not been redeemed.  In the event that the Company does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable Redemption Price (together with any Late Charges thereon) has not been paid.  Upon the Company’s receipt of such notice, (x) any applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y)
the Company shall immediately return this Note, or issue a new Note (in accordance with Section 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 lowest Closing Bid Price of the Common Stock during the period beginning on and including the date on which the Redemption Notice is delivered to the Company and ending on and including the date on which the Redemption Notice is voided.  The Holder’s delivery of a notice voiding a Redemption Notice and exercise of its rights following such notice shall not affect the Company’s obligations to make any payments of Late Charges which have accrued prior to the date of such notice with respect to the Conversion Amount subject to such notice.

                          (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(b) (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 (7) Business Day period beginning on and including the date which is three (3) Business Days prior to the Company’s receipt of the Holder’s Redemption Notice and ending on and including the date which
is three (3) Business Days after the Company’s receipt of the Holder’s Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven Business Day period.

          (16)          PARTICIPATION.  The Holder, as the holder of this Note, shall be entitled to receive such dividends paid and distributions made to the holders of Common Stock to the same extent 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 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.

                          (a)          Transfer by Holder.

Each Person to whom this Note is sold, assigned or transferred by the Holder shall provide to the Company true and accurate information as to such Person comparable to that contained in columns (1), (2) and (7) of the Schedule of Buyers attached to the Securities Purchase Agreement and as to the jurisdiction of residence of such Person.

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.  The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of Section 3(c)(iv) following conversion or redemption of any portion of this Note, the

                          (c)          Note Exchangeable for Different Denominations.  This Note is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Note or Notes (in accordance with Section 19(d) and in principal amounts of at least $100,000) representing in the aggregate the outstanding Principal of this Note, and each such new Note will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

                          (d)          Issuance of New Notes.  Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding (or in the case of a new Note being issued pursuant to Section 19(a) or Section 19(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Note immediately prior to such issuance of new Notes), (iii) shall have an issuance date, as indicated on the face of such new Note, which is the same as the Issuance Date of

The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note.  Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof).  The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate.  The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

- 22 -

          (23)          FAILURE OR INDULGENCE NOT WAIVER.  No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

          (24)          DISPUTE RESOLUTION.  In the case of a dispute as to the determination of the Closing Bid Price, the Closing Sale Price or the Weighted Average Price or the arithmetic calculation of the Conversion Rate or the Redemption Price, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within one (1) Business Day of receipt, or deemed receipt, of the Conversion Notice or Redemption Notice or other event giving rise to such dispute, as the case may be, to the Holder.  If the Holder and the Company are unable to agree upon such determination or calculation within one (1) Business Day of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within one Business Day submit via facsimile (a) the disputed determination of the Closing Bid Price,
the Closing Sale Price or the Weighted Average Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Conversion Rate or the Redemption Price to the Company’s independent, outside accountant.  The Company, at the Company’s expense, shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than five (5) Business Days from the time it receives the disputed determinations or calculations.

Whenever any payment of cash is to be made by the Company to any Person pursuant to this Note, such payment shall be made in lawful money of the United States of America by a check drawn on the account of the Company and sent via overnight courier service to such Person at such address as previously provided to the Company in writing (which address, in the case of each of the Purchasers, shall initially be as set forth on the Schedule of Buyers attached to the Securities Purchase Agreement); provided that the Holder may elect to receive a payment of cash via wire transfer of immediately available funds by providing the Company with prior written notice setting out such request and the Holder’s wire transfer

Any amount of Principal or other amounts due under the Transaction Documents, other than Interest, which is not paid when due shall result in a late charge being incurred and payable by the Company in an amount equal to interest on such amount at the rate of twelve percent (12%) per annum from the date such amount was due until the same is paid in full (“Late Charge”).

          (26)          CANCELLATION.  After all Principal, accrued Interest and other amounts at any time owed on this Note have been paid in full, this Note shall automatically be deemed canceled, shall be surrendered to the Company for cancellation and shall not be reissued.
