AMENDED AND RESTATED SENIOR SECURED CONVERTIBLE NOTE

FOR VALUE RECEIVED, Wentworth Energy, Inc., an Oklahoma corporation (the “Company”), hereby promises to pay to [Insert Name of Buyer] or registered assigns (“Holder”) the amount set out above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the applicable Interest Rate (as defined herein) 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), 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 and supersedes the Senior Secured Convertible Note, dated July 25, 2006 (the “Existing Note”), issued by the Company to the Holder in the Original Principal Amount of $[                     ], but shall not, except as specifically amended hereby or as set forth in the

Amendment Agreements (as defined in Section 29 below), constitute a release, satisfaction or novation of any of the obligations under the Existing Note.  This Note is one of an issue of Amended and Restated Senior Secured Convertible Notes that, together with the Other Notes (as defined in Section 29 below) (this Note and the Other Notes collectively, the “Notes”) were issued pursuant to the Securities Purchase Agreement (as defined in Section 29 below).Certain capitalized terms used herein are defined in Section 29.

(1)           PAYMENTS OF PRINCIPAL.  On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest and accrued and unpaid Late Charges, if any, on such Principal and Interest.  The “Maturity Date” shall be October 31, 2010, as may be extended at the option of the Holder (i) in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1) or any event shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1) that with the passage of time and the failure to cure would result in an Event of Default, (ii) through the date that is ten (10) Business Days after the consummation of a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section 5(b)) is delivered prior to the Maturity Date, and (iii) at any time while this Note is outstanding, by prior written notice thereof by the Holder to the Company, to a date not later than October 31, 2012 (as may be further extended pursuant to this Section 1).

(2)           INTEREST; INTEREST RATE.  (a)  Interest on this Note shall commence accruing on April 1, 2008 and shall be computed on the basis of a 360-day year comprised of twelve (12) thirty (30) day months and shall be payable in arrears for each Calendar Quarter on the first day of the succeeding Calendar Quarter during the period beginning on April 1, 2008 and ending on, and including, the Maturity Date (each, an “Interest Date”) with the first Interest Date being July 1, 2008.  Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in shares of Common Stock (as defined below) (“Interest Shares”) so long as there has been no Equity Conditions Failure; provided however, that the Company may, at its option following notice to the Holder, pay Interest on any Interest Date in cash (“Cash Interest”) or in a combination of Cash Interest and Interest Shares.  The Company shall deliver a written notice (each, an “Interest Election Notice”) to each holder of the Notes on or prior to the Interest Notice Due Date (the date such notice is delivered to all of the holders, the “Interest Notice Date”) which notice (1) either (A) confirms that Interest to be paid on such Interest Date shall be paid entirely in Interest Shares or (B) elects to pay Interest as Cash Interest or a combination of Cash Interest and Interest Shares and specifies the amount of Interest that shall be paid as Cash Interest and the amount of Interest, if any, that shall be paid in Interest Shares and (2) subject to the penultimate sentence in this Section 2(a), certifies that there has been no Equity Conditions Failure; provided, however, that the Company shall not be entitled to pay any portion of Interest on an Interest Date in Interest Shares in excess of the Holder Pro Rata Amount of the applicable Volume Limitation.  If any portion of Interest for a particular Interest Date shall be paid in Interest Shares, then the Company shall pay to the Holder, in accordance with Section 2(b), a number of shares of Common Stock equal to (x) the amount of Interest payable on the applicable Interest Date in Interest Shares divided by (y) the applicable Interest Conversion Price.  Interest to be paid on an

2

Interest Date in Interest Shares shall be paid in a number of fully paid and nonassessable shares of Common Stock (rounded to the nearest whole share).  If the Equity Conditions are not satisfied as of the Interest Notice Due Date, then unless the Company has elected to pay such Interest in cash, the Interest Election Notice shall indicate that unless the Holder and the holders of the Other Notes waive the Equity Conditions, the Interest shall be paid in cash.  If the Equity Conditions were satisfied as of the Interest Notice Due Date but the Equity Conditions are no longer satisfied at any time prior to the Interest Date, the Company shall provide the Holder and the holders of the Other Notes a subsequent notice to that effect indicating that unless the Holder and the holder of the Other Notes waive the Equity Conditions prior to the Interest Date, the Interest shall be paid in cash on the Interest Date.

(b)           When any Interest Shares are to be paid on an Interest Date, the Company shall (i) (A) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program 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 (B) 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 (2) Business Days prior to the applicable Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled and (ii) with respect to each Interest Date, pay to the Holder, in cash by wire transfer of immediately available funds, the amount of any Cash Interest.  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 waived in writing by the Holder and the holders of the Other Notes, there has been an Equity Conditions Failure.

(c)           From and after the occurrence and during the continuance of an Event of Default, the Interest Rate shall be increased to fifteen percent (15.0%) per annum.  In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the date of such cure; provided that the Interest as calculated 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 the issuance and delivery of any 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 $0.001 per share (the “Common Stock”), on the terms and conditions set forth in this Section 3.

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; provided that the Company shall not be required to pay any tax that may be payable in respect of the issuance and delivery of Common Stock to any Person other than the Holder or with respect to any income tax due by the Holder with respect to such Common Stock.

(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, $0.65 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 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).  Accrued and unpaid Interest on any Conversion Amount being converted up to and including the Conversion Date shall be payable to the record holder of this Note on the Share Delivery Date (as defined below) in Interest Shares so long as there has been no Equity Conditions Failure; provided however, that the Company may, at its option following notice to the Holder, pay Interest on any Share Delivery Date as Cash Interest.  On or before the first (1^st) Business Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile a confirmation (the “Conversion Confirmation”) of receipt of such Conversion Notice to the Holder and the Company’s Transfer Agent.  Any Conversion Confirmation delivered by the Company shall (1) confirm that any accrued and unpaid Interest on such Conversion Amount up to and including the Conversion Date shall be paid on the Share Delivery Date in Interest Shares or state that Interest shall be paid as Cash Interest and (2) if the Company shall pay such Interest in Interest Shares, certify that there has been no Equity Conditions Failure.  If Interest shall be paid in Interest Shares, then the Company shall pay such Interest to

4

the Holder on the Share Delivery Date by delivering a number of shares of Common Stock equal to (x) the amount of Interest payable on the applicable Share Delivery Date divided by (y) the applicable Interest Conversion Price. On or before the (3^rd) third Trading Day following the date of delivery of a Conversion Notice (the “Share Delivery Date”), the Company shall (I) (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 (including any 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 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 (including any Interest Shares) to which the Holder shall be entitled and (II) if the Company has elected to pay Cash Interest, pay to the Holder in cash an amount equal to the accrued and unpaid Interest on the Conversion Amount up to and including the Conversion Date.  If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Trading Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with Section 18(d)) representing the outstanding Principal not converted.  The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date.

(ii)           Company’s Failure to Timely Convert.  If the Company shall fail to issue a certificate to the Holder or credit the Holder’s balance account with DTC, as applicable, for the number of shares of Common Stock to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is three (3) Trading Days after the Conversion Date other than pursuant to limitations in Section 3(d) hereof (a “Conversion Failure”), and if on or after such third (3rd) 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 written request and in the Holder’s discretion, either (A) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to issue and deliver such certificate or to 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 shall terminate, or (B) 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 (1) such number of shares of Common Stock, times (2) the Closing Bid Price on the Conversion Date.

(iii)          Registration; Book-Entry.  The Company shall maintain a register (the “Register”) for the recordation of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the “Registered Notes”).  The

5

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

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

(d)           Limitations on Conversions.

(i)            Beneficial Ownership.  Notwithstanding any provision to the contrary contained in this Note or any other Transaction Document, 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) or otherwise pursuant to this Note, to the extent that after giving effect to such conversion, the Holder (together with the Holder’s affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the number of shares of Common Stock outstanding immediately after giving effect to such conversion.  For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted

6

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-K, Form 10-KSB, Form 10-Q, Form 10-QSB, Form 8-K or other public filing with the SEC, as the case may be (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding.  For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported.

(ii)           Principal Market Regulation.  The Company shall not be obligated to issue any shares of Common Stock upon conversion of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue upon conversion or exercise, as applicable, of the Notes and Warrants without breaching the Company’s obligations under the rules or regulations of any applicable Eligible Market (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of such Eligible 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 initial purchaser of the Notes pursuant to the Securities Purchase Agreement (each, a “Purchaser” and collectively the “Purchasers”) shall be issued in the aggregate, upon conversion or exercise or otherwise, as applicable, of the Notes or the 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 such Purchaser pursuant to the Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate principal amount of all Notes and Warrants issued to all of the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”).  In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee.  In the event that any holder of Notes shall convert all of such holder’s Notes into a number of shares of Common Stock which, in the aggregate, is less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Notes on a

7

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 (as defined in the Registration Rights Agreement) 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 seventy (70) 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) subject to the applicable Registration Statement in accordance with the terms of the Registration Rights Agreement, and such lapse or unavailability continues for a period of fifteen (15) 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));

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

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

(v)           the Company’s failure to pay to the Holder any amount of Principal, Redemption Price, Interest, Late Charges or other amounts when and as due under this Note or any other Transaction Document (as defined in the Securities Purchase Agreement) to which the Holder is a party, except, in the case of a failure to pay Interest, Late Charges and other amounts when and as due, in which case only if such failure continues for a period of at least five (5) Business Days;

(ix)           a final judgment or judgments for the payment of money aggregating in excess of $250,000 are rendered against the Company or any of its Subsidiaries and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; provided, however, that any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating the $250,000 amount set forth above so long as the Company provides the Holder a written statement from such insurer or indemnity provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment;

(x)            the Company breaches any representation, warranty, covenant or other term or condition of any Transaction Document, except, in the case of a breach of a covenant or other term or condition of any Transaction Document which is curable, only if such breach continues for a period of at least ten (10) consecutive Business Days; provided that in the case of the failure of the Company timely to file a Registration Statement required to be filed pursuant to the Registration Rights Agreement, only if such failure continues for seventy (70) days after the deadline for filing such Registration Statement under the Registration Rights Agreement;

(xi)           any breach or failure in any respect to comply with Section 14 of this Note, other than a breach of, or failure to comply with, Section 14(c) with respect to a Lien for an amount less than $20,000 on property or assets of the Company which Lien is removed within thirty (30) days of the imposition thereof;

9

(xii)          any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes; or

(xiii)         the SEC commences a formal investigation or enforcement action of the Company and/or its Subsidiaries, or a formal investigation or enforcement action of any of the then current officers or directors of the Company that is related to the Company, its Subsidiaries and/or the Common Stock or enters a consent or other order against the Company and/or its Subsidiaries or any of the then current officers or directors of the Company that is related to the Company, its Subsidiaries and/or the Common Stock.

(b)           Redemption Right.  Upon the occurrence of an Event of Default, the Company shall within one (1) Business Day deliver written notice thereof via facsimile and overnight courier (an “Event of Default Notice”) to the Holder.  At any time after the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to redeem and, in the case the Holder has not received an Event of Default Notice, the Event of Default of which the Holder has become aware; provided, however, that in connection with any Event of Default under Section 4(a)(vi) hereunder, the Holder shall only have the right to require redemption by the Company until a date that is thirty (30) days following the day the default under such Indebtedness has been cured or is no longer continuing or, in the event of any acceleration that has been rescinded, for thirty (30) days after the date of such acceleration.  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 (A) the sum of the Conversion Amount to be redeemed together with accrued and unpaid Interest with respect to such Conversion Amount and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest and (B) the Redemption Premium and (ii) the product of (A) the Conversion Rate with respect to such sum of the Conversion Amount together with accrued and unpaid Interest with respect to such Conversion Amount and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest in effect at such time as the Holder delivers an Event of Default Redemption Notice and (B) the product of (1) the Equity Value Redemption Premium and (2) the greater of (x) the Closing Sale Price of the Common Stock on the date immediately preceding such Event of Default, (y) the Closing Sale Price of the Common Stock on the date immediately after such Event of Default and (z) the Closing Sale Price of the Common Stock on the date the Holder delivers the Event of Default Redemption Notice (the “Event of Default Redemption Price”).  Redemptions required by this Section 4(b) shall be made in accordance with the provisions of Section 12.  To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments.  The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 4(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder.  Accordingly, any Redemption Premium due under this Section 4(b) is intended by the parties to

10

be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

(c)           Sale of Assets.  In connection with any redemption required by Section 4(b) upon an Event of Default of the type described in Section 4(a)(xiii) hereof, in the event the Company does not have sufficient funds to pay the applicable Event of Default Redemption Price, the Required Holders may require the Company to sell or dispose of certain property or assets of the Company and its Subsidiaries, such sale to be consummated for a sale price approved by the Required Holders.  Any such notice by the Required Holders shall be made in writing and shall specify the property or assets such holders of Notes are requiring to be sold.

(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 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 a written instrument substantially similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes then outstanding held by such holder, having similar conversion rights and having similar ranking to the Notes, and satisfactory to the Required Holders 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 (a “Public Successor Entity”).  Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity had been named as the Company herein.  Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Company’s Common Stock (or other securities, cash, assets or other property) issuable upon the conversion or redemption of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity (including its Parent Entity), 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

11

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 twenty (20) Trading Days after the date of the consummation of such Change of Control, the Holder may require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control Redemption Notice”) 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 in cash at a price equal to the greater of (i) 150% of the sum of (x) the Conversion Amount being redeemed and (y) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest through the date of such redemption payment and (ii) the product of (x) the Equity Value Redemption Premium and (y) the sum of (1) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient determined by dividing (I) the aggregate cash consideration and the aggregate cash value of any non-cash consideration per Common Share to be paid to the holders of the Common Shares upon consummation of the Change of Control (any such non-cash consideration consisting of marketable securities to be valued at the higher of the Closing Sale Price of such securities as of the Trading Day immediately prior to, the Closing Sale Price as of the Trading Day immediately following the public announcement of such proposed Change of Control and the Closing Sale Price of the Common Stock immediately prior to the public announcement of such proposed Change of Control) by (II) the Conversion Price plus (2) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed and accrued and unpaid Late Charges, if any, with respect to such Conversion Amount and Interest through the date of such redemption payment, (the “Change of Control Redemption Price”).  Redemptions required by this Section 5 shall be made in accordance with the provisions of Section 12 and shall have priority to payments to stockholders in connection with a Change of Control.  To the extent redemptions required by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments.  Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any interest thereon) is paid in full, the Conversion Amount submitted for redemption under this Section 5(b) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3.  The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder.  Accordingly, any Change of Control redemption premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

(6)           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”),

12

then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

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

(7)           RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

(a)           Adjustment of Conversion Price upon Issuance of Common Stock.  If and whenever on or after the Closing 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 for purposes of the provisions of this Section 7(a) shares of Common Stock issued or sold or deemed to have been issued or sold by the Company in connection with any Excluded Securities) 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 or deemed issuance 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 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 conversion or

13

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 share of 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 “lowest 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 share of 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 increases or decreases at any time, the Conversion Price in effect at the time of such increase or decrease 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 increased or decreased 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 Closing Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible

14

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 increase or decrease.  No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect.  A change that permits the holder of an Option or Convertible Security to utilize a cashless exercise feature shall not be deemed to decrease the consideration payable by the holder solely by reason of the fact that the cashless exercise feature would result in a reduction in cash consideration receivable by the Company.

(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, such Options will be deemed to have been issued for the difference of (x) the aggregate fair market value of such Options and other securities issued or sold in such integrated transaction, less (y) the fair market value of the securities other than such Option, issued or sold in such transaction, and the other securities issued or sold in such integrated transaction will be deemed to have been issued or sold for the balance of the consideration received by the Company.  If any shares of Common Stock are issued or sold, or deemed to have been issued or sold, or provided for in an Option or Convertible Security to be issued or sold for cash, the consideration received or to be received therefor will be deemed to be the net amount received by the Company therefor.  If any shares of Common Stock are issued or sold, or provided for in an Option or Convertible Security to be issued or sold for a consideration other than cash, the amount of the consideration other than cash received or to be received by the Company will be the fair value of such consideration, except where such consideration consists of publicly traded 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 shares of Common Stock 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 shares of Common Stock.  Notwithstanding the provisions of this Section 7(a)(iv), the purchase price provided for in an Option, or the additional consideration, if any, paid or payable upon the issue, conversion, exercise or exchange of any Convertible Securities, to the extent paid or payable or converted or exercised pursuant to a cashless exercise feature, shall not be deemed to be an issuance or sale of Common Stock for consideration other than cash.  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 final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

15

(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 Closing 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 Closing 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.

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

(8)           RIGHT OF REDEMPTION BY HOLDER AND COMPANY.

(a)           Holder’s Right of Mandatory Redemption.  Within fifteen (15) days after each Triggering Date, the Holder shall have the right, in its sole discretion, with the consent of the Required Holders as provided hereafter, to require that the Company redeem a Principal amount of this Note equal to one-third (1/3) of the Original Principal Amount of this Note plus accrued and unpaid Interest and Late Charges, if any, on such Principal and Interest (such amount, the “Holder Redemption Amount” and such election, the “Holder Optional Redemption”), by delivering written notice thereof (such notice, a “Holder Optional Redemption Notice”) no later than the fifteenth (15th) day after the applicable Triggering Date (the date the Holder delivers such notice, the “Holder Optional Redemption Notice Date”).  The Company shall immediately, but no later than one (1) Business Day after receiving the Holder Optional Redemption Notice, forward to the holders of the Other Notes  by facsimile a copy of the Holder Optional Redemption Notice and shall indicate (i) that if such holder  does not deliver written notice to the Company within three (3) Business Days of receipt of such

16

notice objecting to the Holder Optional Redemption, such holder shall be deemed to have given its consent to such Holder Optional Redemption and (ii) that if the consent of the Required Holders is obtained with respect to such Holder Optional Redemption,  the Company’s right to redeem the Full Company Redemption Amount under Section 8(b) shall be triggered.  The Holder agrees that it will be deemed to have given its consent to any Holder Optional Redemption it has initiated.  The Holder further agrees, in the case of a Holder Optional Redemption initiated by any holder of the Other Notes, that it will be deemed to have given its consent thereto if the Holder fails to deliver its objection notice to the Company within three (3) Business Days of receipt of such notice from the Company.  Within fifteen (15) days after the Holder Optional Redemption Notice Date, the Company shall deliver to the Holder a written notice (a “Company Redemption Notice” and the date the Holder receives such written notice, the “Company Redemption Notice Date”) which notice shall either (i) state that the Required Holders have not consented to the Holder Optional Redemption, in which case the Holder Optional Redemption and the Holder Optional Redemption Notice shall be null and void and of no further force and effect or (ii) state that the Required Holders have consented or are deemed to have consented to the Holder Optional Redemption, in which case the Company Redemption Notice shall (A) state the date on which the Holder Optional Redemption shall occur (the “Holder Optional Redemption Date”) which date shall be no later than forty-five (45) days after the Holder Optional Redemption Notice Date and (B) confirm (x) that the Company shall redeem the Holder Redemption Amount at the Holder Optional Redemption Price or (y) that the Company is making a Company Full Mandatory Redemption, in which case, redemption of the Holder Redemption Amount shall be governed by the terms of Section 8(b) below.  Each Company Redemption Notice shall be irrevocable.  Notwithstanding anything to the contrary in this Section 8(a), until the Holder Optional Redemption Price is paid in full, the Holder Redemption Amount may be converted, in whole or in part, by the Holder into shares of Common Stock pursuant to Section 3.  All Conversion Amounts converted by the Holder after the Company Redemption Notice Date shall reduce the Holder Redemption Amount required to be redeemed on the applicable Holder Optional Redemption Date.  Holder Optional Redemptions made pursuant to this Section 8(a) shall be made in accordance with Section 12.

(b)           Company’s Right of Mandatory Redemption.

(i)            Provided that there has been no Equity Conditions Failure, the Company shall have the right to elect to redeem (a “Company Partial Mandatory Redemption”) a Principal amount of this Note equal to up to one-third (1/3) of the Original Principal Amount of this Note plus accrued and unpaid Interest and Late Charges, if any, on such Principal and Interest (such elected amount, the “Partial Company Redemption Amount”) at the Partial Company Redemption Price.  If the Company elects to make the Company Partial Mandatory Redemption under this clause (i), the Company must make the same election with respect to each of the Other Notes (and analogous provisions under the Other Notes).

(ii)           Provided that no Event of Default has occurred and is continuing and the Holder has elected to exercise its Holder Optional Redemption pursuant to Section 8(a) above, then the Company shall have the right to redeem (a “Company Full Mandatory Redemption”) an amount equal to 100% of the outstanding Principal of this Note, accrued and unpaid Interest and Late Charges, if any, on such Principal and Interest on this Note

17

plus any other amounts due and owing under this Note in its entirety (the “Full Company Redemption Amount,” and each of the Partial Company Redemption Amount and the Full Company Redemption Amount, a “Company Redemption Amount”) at the Company Mandatory Redemption Price.

(iii)          The Company may exercise its redemption rights under clause (i) or (ii) of this Section 8(b) by delivering a written notice thereof no later than the fifteenth (15th) day after (A) the applicable Triggering Date in the case of a Company Partial Mandatory Redemption and (B) the Holder Optional Redemption Notice Date, in the case of a Company Full Mandatory Redemption by confirmed facsimile and overnight courier to all, but not less than all, of the holders of the Notes (the “Company Mandatory Redemption Notice” and the date such notice is delivered to all the holders is referred to as the “Company Mandatory Redemption Notice Date”).  The Company Mandatory Redemption Notice shall be irrevocable.  The Company Mandatory Redemption Notice shall state (A) the date on which the Company Partial Mandatory Redemption or Company Full Mandatory Redemption, as applicable, shall occur (the “Company Mandatory Redemption Date”) which date shall not be less than forty-five (45) days after the Company Mandatory Redemption Notice Date and not more than a number of days as agreed to by the Required Holders, in the case of a Company Partial Mandatory Redemption and the Holder, in the case of a Company Full Mandatory Redemption, (B) (x) that, pursuant to Section 8(b)(i) hereof, the Company elects to redeem the Partial Company Redemption Amount at the Partial Company Redemption Price or (y) that, pursuant to Section 8(b)(ii) hereof, (I) that the Company elects to redeem the Full Company Redemption Amount at the Company Mandatory Redemption Price on the Company Mandatory Redemption Date and (II) that in connection with the Company Full Mandatory Redemption, the Series B Warrants shall become exercisable as of the Company Mandatory Redemption Date in accordance with their terms.  Notwithstanding anything to the contrary in this Section 8(b), until the Partial Company Redemption Price or the Company Mandatory Redemption Price, as the case may be, is paid in full, the Company Redemption Amount may be converted, in whole or in part, by the Holder into shares of Common Stock pursuant to Section 3.  All Conversion Amounts converted by the Holder after the Company Mandatory Redemption Notice Date shall reduce the Company Redemption Amount required to be redeemed on the Company Mandatory Redemption Date.  Redemptions made pursuant to this Section 8(b) shall be made in accordance with Section 12.

(9)           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).

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

18

(11)         RESERVATION OF AUTHORIZED SHARES.

(a)           Reservation.  Immediately on and after the Closing Date, the Company shall reserve out of its authorized and unissued a number of shares of Common Stock for each of the Notes equal to 130% of the Conversion Rate with respect to the Conversion Amount of each such Note as of the Closing Date and, for so long thereafter 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, 130% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding(without regard to any limitations on conversions) (such applicable amount, the “Required Reserve Amount”).  The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the principal amount of the Notes held by each holder at the 2007 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 best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.

(12)         REDEMPTIONS.

(a)           Mechanics.  The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five (5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice.  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 concurrently with the consummation of such Change of Control if such notice is received at least one (1) Business Day prior to the consummation of such Change of Control and within five (5) Business Days after the

19

Company’s receipt of such notice otherwise.  The Company shall deliver (i) the applicable Company Mandatory Redemption Price to the Holder on the Company Mandatory Redemption Date, and (ii) subject to the provisions of Section 8, the applicable Holder Optional Redemption Price on the applicable Holder 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 18(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) the applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall immediately return this Note, or issue a new Note (in accordance with Section 18(d)) to the Holder representing the sum of such Conversion Amount to be 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 (z) the Conversion Price of this Note or such new Notes shall be adjusted to the lesser of (A) the Conversion Price as in effect on the date on which the applicable Redemption Notice is voided and (B) the lowest Closing Bid Price of the Common Stock during the period beginning on and including the date on which the applicable Redemption Notice is delivered to the Company and ending on and including the date on which the applicable Redemption Notice is voided.  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), Section 5(b) or Section 8 (each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day after its receipt thereof, forward to the Holder by facsimile a copy of such notice.  If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including the date which is three (3) Business Days prior to the Company’s receipt of the Holder’s Redemption Notice and ending on and including the date which is three (3) Business Days after the Company’s receipt of the Holder’s Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such seven (7) Business Day period.

20

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

(14)         COVENANTS.  So long as this Note is outstanding:

(a)           Rank.      All payments due under this Note shall rank pari passu with all Other Notes and no other Indebtedness of the Company and its Subsidiaries shall be senior to the Indebtedness of the Company and its Subsidiaries evidenced by this Note and the Other Notes other than Indebtedness of any subsidiary of the Company that is non-recourse to the Company and any other Subsidiary.

(b)           Incurrence of Indebtedness.  The Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness, other than the Indebtedness evidenced by this Note and the Other Notes and other Permitted Indebtedness.

(c)           Existence of Liens.  The Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, allow or suffer to exist any mortgage, lien, pledge, charge, security interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by the Company or any of its Subsidiaries (collectively, “Liens”) other than Permitted Liens.

(d)           Restricted Payments.  The Company shall not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, redeem, defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole or in part, whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any Permitted Indebtedness, whether by way of payment in respect of principal of (or premium, if any) or interest on, such Indebtedness if at the time such payment is due or is otherwise made or, after giving effect to such payment, an event constituting, or that with the passage of time and without being cured would constitute, an Event of Default has occurred and is continuing.

(e)           Restriction on Redemption and Cash Dividends.  Until all of the Notes have been converted, redeemed or otherwise satisfied in accordance with their terms, the Company shall not, directly or indirectly, redeem, repurchase or declare or pay any cash dividend or distribution on its capital stock without the prior express written consent of the Required Holders; provided that the Company shall be entitled to make the Excluded Distribution without the prior written consent of the Required Holders (subject to the Company’s compliance with the Holder’s participation right set forth in Section 15).

(f)            Use of Proceeds.  The Company will use the proceeds from the sale of the Notes substantially as set forth on Schedule 4(d) to the Securities Purchase Agreement.

21

(1)   The Company shall not make or commit or agree to make, or permit any of its Subsidiaries to make or commit or agree to make, any Capital Expenditure (by purchase or Capitalized Lease) not in the ordinary course of its business (“Non Ordinary Course Capital Expenditures”) without the prior written consent of the Required Holders (which consent shall be in their sole discretion); provided, that, it is understood that Capital Expenditures in connection with (i) the drilling of any well-site, (ii) the purchase or lease of any real property, or (iii) the purchase or lease of any asset with a fair market value in excess of $50,000, shall be deemed to be Non Ordinary Course Capital Expenditures.

(2)   The Company shall obtain the written consent of the Required Holders by sending to each Holder a notice (a “Non Ordinary Course Capital Expenditure Request”) setting forth the material details of such Non Ordinary Course Capital Expenditure.  If the Company is required to disclose material, nonpublic information to the Holder in such Non Ordinary Course Capital Expenditure Request, the Company shall, before delivering any such Non Ordinary Course Capital Expenditure Request, first provide a notice (a “Request To Give MNPI”) to each of the Holders of the Notes stating that it seeks the consent required under this Section 14(g) and that it is necessary to give such Holder material, nonpublic information in connection with such consent.  Such Request To Give MNPI shall only include information that the Company does not deem to be material, nonpublic information.  The Holder shall have two (2) Trading Days after receipt of a Request To Give MNPI to notify the Company of its election to receive such material, nonpublic information or to decline to receive such material, nonpublic information.  If the Holder declines to receive such material, nonpublic information, (i) the Holder shall state in such election whether it is consenting to the related Non Ordinary Course Capital Expenditure or withholding its consent and (ii) the Company shall not deliver such Non Ordinary Course Capital Expenditure Request which contains material, nonpublic information to any Holder that so declines.  If the Holder elects to receive such material, nonpublic information, the Company may deliver to the Holder such Non Ordinary Course Capital Expenditure Request.  If the Holder has not received a Request To Give MNPI prior to receipt of a Non Ordinary Course Capital Expenditure Request, the Holder may presume that all matters relating to such Non Ordinary Course Capital Expenditure Request do not constitute material, nonpublic information.

(3)   The Holder shall have twenty (20) Business Days to respond to any Non Ordinary Course Capital Expenditure Request if such request relates to a Non Ordinary Course Capital Expenditure proposed by the Company and five (5) Business Days to respond to any Non Ordinary Course Capital Expenditure Request if it relates to a Non Ordinary Course Capital Expenditure proposed by a third party.

(4)   If the Company has delivered to the Holder any material, nonpublic information in connection with this Section 14(g) and the Holder delivers notice to the Company requesting to be cleansed of such material, nonpublic information, the Company shall within five (5) Trading Days of receipt of such notice, make a public disclosure (on a Current Report on Form 8-K or otherwise) of such material, nonpublic information.

(16)         VOTE TO ISSUE, OR CHANGE THE TERMS OF, NOTES.  The affirmative vote at a meeting duly called for such purpose or the written consent without a meeting of the Required Holders shall be required for any amendment, modification or waiver to this Note or the Other Notes.  No such amendment, modification or waiver shall be effective to the extent that it applies to less than all of the holders of the Notes then outstanding.  In no event shall any such amendment, modification or waiver be made to this Note which would adversely affect the Holder without the written consent of the Holder, provided that the Holder’s written consent shall not be required for amendments, modifications or waivers to the provisions of Sections 11, 14 (other than Section 14(a)), 18 or 30 that are consented to in writing by the Required Holders and that would not disproportionately adversely affect the Holder.

(22)         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.
