    Due
      January 17, 2009

     

    This
      Secured Convertible Debenture (the “Debenture”)
      is
      issued by TRIANGLE
      PETROLEUM CORPORATION, a
      Nevada
      corporation (the “Obligor”),
      to
CORNELL
      CAPITAL PARTNERS, LP
      (the
“Holder”),
      pursuant to that certain Securities Purchase Agreement (the “Securities
      Purchase Agreement”)
      dated
      December 8, 2005. 

     

    FOR
      VALUE RECEIVED,
      the
      Obligor hereby promises to pay to the Holder or its successors and assigns
      the
      principal sum of Five Million Dollars ($5,000,000) together with accrued but
      unpaid interest on or before January 17, 2009 (the “Maturity
      Date”)
      in
      accordance with the following terms:

     

    Interest.
      Interest shall accrue on the outstanding principal balance hereof at an annual
      rate equal to five percent (5%). Interest shall be calculated on the basis
      of a
      365-day year and the actual number of days elapsed, to the extent permitted
      by
      applicable law. Interest hereunder will be paid to the Holder or its assignee
      (as defined in Section
      5)
      in
      whose name this Debenture is registered on the records of the Obligor regarding
      registration and transfers of Debentures (the “Debenture
      Register”)
      and
      shall be paid in cash or in Common Stock at the Conversion Price in effect
      at
      the time payment is made, at the option of the Obligor.

     

    Right
      of Redemption.
      The
      Obligor at its option shall have the right, with three (3) business days advance
      written notice (the “Redemption
      Notice”),
      to
      redeem a portion or all amounts outstanding under this Debenture prior to the
      Maturity Date provided that the Closing Bid Price of the of the Obligor’s Common
      Stock, as reported by Bloomberg, LP, is less than the Fixed Conversion Price
      at
      the time of the Redemption Notice. The Obligor shall pay an amount equal to
      the
      principal amount being redeemed plus a redemption premium (“Redemption
      Premium”)
      equal
      to twenty percent (20%) of the principal amount being redeemed, and accrued
      interest, (collectively referred to as the “Redemption
      Amount”).
      The
      Obligor shall deliver to the Holder the Redemption Amount on the third
      (3rd)
      business day after the Redemption Notice. 

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    Notwithstanding
      the foregoing in the event that the Obligor has elected to redeem a portion
      of
      the outstanding principal amount and accrued interest under this Debenture
      the
      Holder shall be permitted to convert all or any portion of this Debenture during
      such three business day period.

     

    Security
      Agreements.
      This
      Debenture is secured by a security agreement (the “Security
      Agreement”)
      dated
      December 8, 2005 between the Obligor and the Holder, a security agreement dated
      December 8, 2005 between Elmworth Energy Corp. and the Holder (the “Elmworth
      Security Agreement”),
      and a
      security agreement dated December 8, 2005 between Triangle USA Petroleum Corp.
      and the Holder (the “Triangle
      USA Security Agreement”).

     

    Consent
      of Holder to Sell Capital Stock or Grant Security Interests.
      So
      long
      as any of the principal amount or interest on this Debenture remains unpaid

      in
      any of the assets of the Obligor, or

      registration statements on Form S-8. Notwithstanding the forgoing, the Obligor
      shall be permitted to issue or sell the following shares of Common Stock or
      securities convertible or exercisable into Common Stock which would otherwise
      require prior consent of the Holder without the prior consent of the Holder:

      Warrants to purchase up to 1,250,000 shares of Common Stock (“Permitted
      Warrants”)

      such Permitted Warrants, and (z) up to 100,000 shares of Common Stock which
      do
      not fall into any one of the other categories above (“Permitted
      Shares”
and
      collectively with the Permitted Stock Grants, Permitted Debentures and Permitted
      Warrants, the “Permitted
      Issuances”).

    Section
      1. This
      Debenture is exchangeable for an equal aggregate principal amount of Debentures

      or

      due and payable;

      and
      shall not again be quoted or listed for trading thereon within five (5) Trading
      Days of such delisting;

     

    (vi) The
      Obligor or any subsidiary of the Obligor shall be a party to any Change of

    (viii) If

      reason or the Holder shall not be permitted to resell the shares of Common

      eight Trading Days (which need not be consecutive Trading Days);

     

    (ix) The
      Obligor shall fail for any reason to deliver Common Stock certificates to a

      interest and other amounts owing in respect thereof, to the date of acceleration
      shall become at the Holder's election, immediately due and payable in cash,
      provided

    Section
      3. Conversion.

     

    (a) Conversion
      at Option of Holder.

     

    (i) This
      Debenture shall be convertible into shares of Common Stock at the option of
      the
      Holder, in whole or in part at any time and from time to time, after the
      Original Issue Date (as defined in Section
      5)
      (subject to the limitations on conversion set forth in Section
      3(b)
      hereof).
      The number of shares of Common Stock issuable upon a conversion hereunder equals
      the quotient obtained by dividing (x) the outstanding amount of this Debenture
      to be converted by (y) the Conversion Price (as defined in Section
      3(c)(i)).
      The
      Obligor shall deliver Common Stock certificates to the Holder prior to the
      Fifth
      (5th)
      Trading
      Day after a Conversion Date.

     

    (ii) Notwithstanding
      anything to the contrary contained herein, if on any Conversion Date: (1) the
      number of shares of Common Stock at the time authorized, unissued and unreserved
      for all purposes, or held as treasury stock, is insufficient to pay principal
      hereunder in shares of Common Stock; (2) the Common Stock is not listed or
      quoted for trading on the OTC or on a Subsequent Market; (3) the Obligor has
      failed to timely satisfy its conversion; or (4) the issuance of such shares
      of
      Common Stock would result in a violation of Section
      3(b),
      then,
      at the option of the Holder, the Obligor, in lieu of delivering shares of Common
      Stock pursuant to Section
      3(a)(i),
      shall
      deliver, within three (3) Trading Days of each applicable Conversion Date,
      an
      amount in cash equal to the product of the outstanding principal amount to
      be
      converted plus any interest due therein divided by the Conversion Price and
      multiplied by the highest closing price of the stock from date of the conversion
      notice till the date that such cash payment is made. Upon receipt of such cash
      payment by the Holder, the outstanding amount of this Debenture shall be reduced
      by the outstanding amount of this Debenture that was to be converted.

     

    Further,
      if the Obligor shall not have delivered any cash due in respect of conversion
      of
      this Debenture or as payment of interest thereon by the fifth (5th)
      Trading
      Day after the Conversion Date, the Holder may, by notice to the Obligor, require
      the Obligor to issue shares of Common Stock pursuant to Section
      3(c),
      except
      that for such purpose the Conversion Price applicable thereto shall be the
      lesser of the Conversion Price on the Conversion Date and the Conversion Price
      on the date of such Holder demand. Any such shares will be subject to the
      provisions of this Section.

     

    (iii) The
      Holder shall effect conversions by delivering to the Obligor a completed notice
      in the form attached hereto as Exhibit A (a “Conversion
      Notice”).
      The
      date on which a Conversion Notice is delivered is the “Conversion
      Date.”
Unless
      the Holder is converting the entire principal amount outstanding under this
      Debenture, the Holder is not required to physically surrender this Debenture
      to
      the Obligor in order to effect conversions. Conversions hereunder shall have
      the
      effect of lowering the outstanding principal amount of this Debenture plus
      all
      accrued and unpaid interest thereon in an amount equal to the applicable
      conversion. The Holder and the Obligor shall maintain records showing the
      principal amount converted and the date of such conversions. 

     

    (b) Certain
      Conversion Restrictions.

     

    
      
         

      

      
        5

        
          

        

      

      
         

      

    

     

    (i) A
      Holder
      may not convert this Debenture or receive shares of Common Stock as payment
      of
      interest hereunder to the extent such conversion or receipt of such interest
      payment would result in the Holder, together with any affiliate thereof,
      beneficially owning (as determined in accordance with Section 13(d) of the
      Exchange Act and the rules promulgated thereunder) in excess of 4.9% of the
      then
      issued and outstanding shares of Common Stock, including shares issuable upon
      conversion of, and payment of interest on, this Debenture held by such Holder
      after application of this Section. Since the Holder will not be obligated to
      report to the Obligor the number of shares of Common Stock it may hold at the
      time of a conversion hereunder, unless the conversion at issue would result
      in
      the issuance of shares of Common Stock in excess of 4.9% of the then outstanding
      shares of Common Stock without regard to any other shares which may be
      beneficially owned by the Holder or an affiliate thereof, the Holder shall
      have
      the authority and obligation to determine whether the restriction contained
      in
      this Section will limit any particular conversion hereunder and to the extent
      that the Holder determines that the limitation contained in this Section
      applies, the determination of which portion of the principal amount of this
      Debenture is convertible shall be the responsibility and obligation of the
      Holder. If the Holder has delivered a Conversion Notice for a principal amount
      of this Debenture that, without regard to any other shares that the Holder
      or
      its affiliates may beneficially own, would result in the issuance in excess
      of
      the permitted amount hereunder, the Obligor shall notify the Holder of this
      fact
      and shall honor the conversion for the maximum principal amount permitted to
      be
      converted on such Conversion Date in accordance with the periods described
      in
Section
      3(a)(i)
      and, at
      the option of the Holder, either retain any principal amount tendered for
      conversion in excess of the permitted amount hereunder for future conversions
      or
      return such excess principal amount to the Holder. The provisions of this
      Section may be waived by a Holder (but only as to itself and not to any other
      Holder) upon not less than 65 days prior notice to the Obligor. Other Holders
      shall be unaffected by any such waiver.

     

    (ii) Unless
      waived by the Obligor, in no event shall the Holder, together with its
      affiliates, be entitled to convert more than an aggregate of $1,500,000 of
      principal amount of this Debenture together with all other debentures issued
      to
      the Holder in connection with the Securities Purchase Agreement in any thirty
      (30) day period, of which no more than $1,000,000 of such amount may be
      converted by the Holder at the Market Conversion Price. Upon the occurrence
      of
      an Event of Default, the restriction set forth in this section shall not apply.
        

     

    (c) Conversion
      Price and Adjustments to Conversion Price.

     

    (i) The
      conversion price shall equal the lesser of (i) a price equal to Five Dollars
      ($5.00) (the “Fixed
      Conversion Price”)
      or
      (ii) ninety percent (90%) of the average of the three (3) lowest daily
      Volume Weighted Average Prices of the Common Stock during the ten (10) trading
      days immediately preceding the Conversion Date as quoted by Bloomberg, LP (the
      “Market
      Conversion Price”).
      (The
      Fixed Conversion Price and the Market Conversion Price are collectively referred
      to as the “Conversion
      Price”).
      The
      Conversion Price may be adjusted pursuant to the other terms of this
      Debenture.

     

    (ii) If
      the
      Obligor, at any time while this Debenture is outstanding, shall (a) pay a
      stock dividend or otherwise make a distribution or distributions on shares
      of
      its Common Stock or any other equity or equity equivalent securities payable
      in
      shares of Common Stock, (b) subdivide outstanding shares of Common Stock into
      a
      larger number of shares, (c) combine (including by way of reverse stock split)
      outstanding shares of Common Stock into a smaller number of shares, or (d)
      issue
      by reclassification of shares of the Common Stock any shares of capital stock
      of
      the Obligor, then the Fixed Conversion Price shall be multiplied by a fraction
      of which the numerator shall be the number of shares of Common Stock (excluding
      treasury shares, if any) outstanding before such event and of which the
      denominator shall be the number of shares of Common Stock outstanding after
      such
      event. Any adjustment made pursuant to this Section shall become effective
      immediately after the record date for the determination of stockholders entitled
      to receive such dividend or distribution and shall become effective immediately
      after the effective date in the case of a subdivision, combination or
      re-classification.

    (iii) If
      the
      Obligor, at any time while this Debenture is outstanding, shall issue rights,
      options or warrants to all holders of Common Stock (and not to the Holder)
      entitling them to subscribe for or purchase shares of Common Stock at a price
      per share less than the Fixed Conversion Price (except for Permitted Issuances),
      then the Fixed Conversion Price shall be multiplied by a fraction, of which
      the
      denominator shall be the number of shares of the Common Stock (excluding
      treasury shares, if any) outstanding on the date of issuance of such rights
      or
      warrants (plus the number of additional shares of Common Stock offered for
      subscription or purchase), and of which the numerator shall be the number of
      shares of the Common Stock (excluding treasury shares, if any) outstanding
      on
      the date of issuance of such rights or warrants, plus the number of shares
      which
      the aggregate offering price of the total number of shares so offered would
      purchase at the Fixed Conversion Price. Such adjustment shall be made whenever
      such rights or warrants are issued, and shall become effective immediately
      after
      the record date for the determination of stockholders entitled to receive such
      rights, options or warrants. However, upon the expiration of any such right,
      option or warrant to purchase shares of the Common Stock the issuance of which
      resulted in an adjustment in the Fixed Conversion Price pursuant to this
      Section, if any such right, option or warrant shall expire and shall not have
      been exercised, the Fixed Conversion Price shall immediately upon such
      expiration be recomputed and effective immediately upon such expiration be
      increased to the price which it would have been (but reflecting any other
      adjustments in the Fixed Conversion Price made pursuant to the provisions of
      this Section after the issuance of such rights or warrants) had the adjustment
      of the Fixed Conversion Price made upon the issuance of such rights, options
      or
      warrants been made on the basis of offering for subscription or purchase only
      that number of shares of the Common Stock actually purchased upon the exercise
      of such rights, options or warrants actually exercised.

     

    (iv) If
      the
      Obligor or any subsidiary thereof, as applicable, at any time while this
      Debenture is outstanding, shall issue, except for Permitted Issuances, shares
      of
      Common Stock or rights, warrants, options or other securities or debt that
      are
      convertible into or exchangeable for shares of Common Stock (“Common
      Stock Equivalents”)
      entitling any Person to acquire shares of Common Stock, at a price per share
      less than the Fixed Conversion Price (if the holder of the Common Stock or
      Common Stock Equivalent so issued shall at any time, whether by operation of
      purchase price adjustments, reset provisions, floating conversion, exercise
      or
      exchange prices or otherwise, or due to warrants, options or rights per share
      which is issued in connection with such issuance, be entitled to receive shares
      of Common Stock at a price per share which is less than the Fixed Conversion
      Price, such issuance shall be deemed to have occurred for less than the Fixed
      Conversion Price), then, at the sole option of the Holder, the Fixed Conversion
      Price shall be adjusted to mirror the conversion, exchange or purchase price
      for
      such Common Stock or Common Stock Equivalents (including any reset provisions
      thereof) at issue. Such adjustment shall be made whenever such Common Stock
      or
      Common Stock Equivalents are issued. The Obligor shall notify the Holder in
      writing, no later than one (1) business day following the issuance of any Common
      Stock or Common Stock Equivalent subject to this Section, indicating therein
      the
      applicable issuance price, or of applicable reset price, exchange price,
      conversion price and other pricing terms. No adjustment under this Section
      shall
      be made as a result of issuances and exercises of options to purchase shares
      of
      Common Stock issued for compensatory purposes pursuant to any of the Obligor's
      stock option or stock purchase plans.

    (v) If
      the
      Obligor, at any time while this Debenture is outstanding, shall distribute
      to
      all holders of Common Stock (and not to the Holder) evidences of its
      indebtedness or assets or rights or warrants to subscribe for or purchase any
      security, then in each such case the Fixed Conversion Price at which this
      Debenture shall thereafter be convertible shall be determined by multiplying
      the
      Fixed Conversion Price in effect immediately prior to the record date fixed
      for
      determination of stockholders entitled to receive such distribution by a
      fraction of which the denominator shall be the Closing Bid Price determined
      as
      of the record date mentioned above, and of which the numerator shall be such
      Closing Bid Price on such record date less the then fair market value at such
      record date of the portion of such assets or evidence of indebtedness so
      distributed applicable to one outstanding share of the Common Stock as
      determined by the Board of Directors in good faith. In either case the
      adjustments shall be described in a statement provided to the Holder of the
      portion of assets or evidences of indebtedness so distributed or such
      subscription rights applicable to one share of Common Stock. Such adjustment
      shall be made whenever any such distribution is made and shall become effective
      immediately after the record date mentioned above.

     

    (vi) In
      case
      of any reclassification of the Common Stock or any compulsory share exchange
      pursuant to which the Common Stock is converted into other securities, cash
      or
      property, the Holder shall have the right thereafter to, at its option, (A)
      convert the then outstanding principal amount, together with all accrued but
      unpaid interest and any other amounts then owing hereunder in respect of this
      Debenture into the shares of stock and other securities, cash and property
      receivable upon or deemed to be held by holders of the Common Stock following
      such reclassification or share exchange, and the Holder of this Debenture shall
      be entitled upon such event to receive such amount of securities, cash or
      property as the shares of the Common Stock of the Obligor into which the then
      outstanding principal amount, together with all accrued but unpaid interest
      and
      any other amounts then owing hereunder in respect of this Debenture could have
      been converted immediately prior to such reclassification or share exchange
      would have been entitled, or (B) require the Obligor to prepay the outstanding
      principal amount of this Debenture, plus all interest and other amounts due
      and
      payable thereon. The entire prepayment price shall be paid in cash. This
      provision shall similarly apply to successive reclassifications or share
      exchanges.

     

    (vii) The
      Obligor shall at all times reserve and keep available out of its authorized
      Common Stock the full number of shares of Common Stock issuable upon conversion
      of all outstanding amounts under this Debenture; and within three (3) Business
      Days following the receipt by the Obligor of a Holder's notice that such minimum
      number of Underlying Shares is not so reserved, the Obligor shall promptly
      reserve a sufficient number of shares of Common Stock to comply with such
      requirement.

    (viii) All
      calculations under this Section
      3
      shall be
      rounded up to the nearest $0.001 or whole share.

     

    (ix) Whenever
      the Conversion Price is adjusted pursuant to Section
      3
      hereof,
      the Obligor shall promptly mail to the Holder a notice setting forth the
      Conversion Price after such adjustment and setting forth a brief statement
      of
      the facts requiring such adjustment.

     

    (x) If
      (A)
      the Obligor shall declare a dividend (or any other distribution) on the Common
      Stock; (B) the Obligor shall declare a special nonrecurring cash dividend on
      or
      a redemption of the Common Stock; (C) the Obligor shall authorize the granting
      to all holders of the Common Stock rights or warrants to subscribe for or
      purchase any shares of capital stock of any class or of any rights; (D) the
      approval of any stockholders of the Obligor shall be required in connection
      with
      any reclassification of the Common Stock, any consolidation or merger to which
      the Obligor is a party, any sale or transfer of all or substantially all of
      the
      assets of the Obligor, of any compulsory share exchange whereby the Common
      Stock
      is converted into other securities, cash or property; or (E) the Obligor shall
      authorize the voluntary or involuntary dissolution, liquidation or winding
      up of
      the affairs of the Obligor; then, in each case, the Obligor shall cause to
      be
      filed at each office or agency maintained for the purpose of conversion of
      this
      Debenture, and shall cause to be mailed to the Holder at its last address as
      it
      shall appear upon the stock books of the Obligor, at least twenty (20) calendar
      days prior to the applicable record or effective date hereinafter specified,
      a
      notice stating (x) the date on which a record is to be taken for the purpose
      of
      such dividend, distribution, redemption, rights or warrants, or if a record
      is
      not to be taken, the date as of which the holders of the Common Stock of record
      to be entitled to such dividend, distributions, redemption, rights or warrants
      are to be determined or (y) the date on which such reclassification,
      consolidation, merger, sale, transfer or share exchange is expected to become
      effective or close, and the date as of which it is expected that holders of
      the
      Common Stock of record shall be entitled to exchange their shares of the Common
      Stock for securities, cash or other property deliverable upon such
      reclassification, consolidation, merger, sale, transfer or share exchange,
      provided, that the failure to mail such notice or any defect therein or in
      the
      mailing thereof shall not affect the validity of the corporate action required
      to be specified in such notice. The Holder is entitled to convert this Debenture
      during the 20-day calendar period commencing the date of such notice to the
      effective date of the event triggering such notice.

     

    (xi) In
      case
      of any (1) merger or consolidation of the Obligor or any subsidiary of the
      Obligor with or into another Person, or (2) sale by the Obligor or any
      subsidiary of the Obligor of more than one-half of the assets of the Obligor
      in
      one or a series of related transactions, a Holder shall have the right to (A)
      exercise any rights under Section
      2(b),
      (B)
      convert the aggregate amount of this Debenture then outstanding into the shares
      of stock and other securities, cash and property receivable upon or deemed
      to be
      held by holders of Common Stock following such merger, consolidation or sale,
      and such Holder shall be entitled upon such event or series of related events
      to
      receive such amount of securities, cash and property as the shares of Common
      Stock into which such aggregate principal amount of this Debenture could have
      been converted immediately prior to such merger, consolidation or sales would
      have been entitled, or (C) in the case of a merger or consolidation, require
      the
      surviving entity to issue to the Holder a convertible Debenture with a principal
      amount equal to the aggregate principal amount of this Debenture then held
      by
      such Holder, plus all accrued and unpaid interest and other amounts owing
      thereon, which such newly issued convertible Debenture shall have terms
      identical (including with respect to conversion) to the terms of this Debenture,
      and shall be entitled to all of the rights and privileges of the Holder of
      this
      Debenture set forth herein and the agreements pursuant to which this Debentures
      were issued. In the case of clause (C), the conversion price applicable for
      the
      newly issued shares of convertible preferred stock or convertible Debentures
      shall be based upon the amount of securities, cash and property that each share
      of Common Stock would receive in such transaction and the Conversion Price
      in
      effect immediately prior to the effectiveness or closing date for such
      transaction. The terms of any such merger, sale or consolidation shall include
      such terms so as to continue to give the Holder the right to receive the
      securities, cash and property set forth in this Section upon any conversion
      or
      redemption following such event. This provision shall similarly apply to
      successive such events.

    (d) Other
      Provisions.

     

    (i) The
      Obligor covenants that it will at all times reserve and keep available out
      of
      its authorized and unissued shares of Common Stock solely for the purpose of
      issuance upon conversion of this Debenture and payment of interest on this
      Debenture, each as herein provided, free from preemptive rights or any other
      actual contingent purchase rights of persons other than the Holder, not less
      than such number of shares of the Common Stock as shall (subject to any
      additional requirements of the Obligor as to reservation of such shares set
      forth in this Debenture) be issuable (taking into account the adjustments and
      restrictions of Sections
      2(b) and 3(c))
      upon
      the conversion of the outstanding principal amount of this Debenture and payment
      of interest hereunder. The Obligor covenants that all shares of Common Stock
      that shall be so issuable shall, upon issue, be duly and validly authorized,
      issued and fully paid, nonassessable and, if the Underlying Shares Registration
      Statement has been declared effective under the Securities Act, registered
      for
      public sale in accordance with such Underlying Shares Registration
      Statement.

     

    (ii) Upon
      a
      conversion hereunder the Obligor shall not be required to issue stock
      certificates representing fractions of shares of the Common Stock, but may
      if
      otherwise permitted, make a cash payment in respect of any final fraction of
      a
      share based on the Closing Bid Price at such time. If the Obligor elects not,
      or
      is unable, to make such a cash payment, the Holder shall be entitled to receive,
      in lieu of the final fraction of a share, one whole share of Common
      Stock.

     

    (iii) The
      issuance of certificates for shares of the Common Stock on conversion of this
      Debenture shall be made without charge to the Holder thereof for any documentary
      stamp or similar taxes that may be payable in respect of the issue or delivery
      of such certificate, provided that the Obligor shall not be required to pay
      any
      tax that may be payable in respect of any transfer involved in the issuance
      and
      delivery of any such certificate upon conversion in a name other than that
      of
      the Holder of such Debenture so converted and the Obligor shall not be required
      to issue or deliver such certificates unless or until the person or persons
      requesting the issuance thereof shall have paid to the Obligor the amount of
      such tax or shall have established to the satisfaction of the Obligor that
      such
      tax has been paid.

     

    (iv) Nothing
      herein shall limit a Holder's right to pursue actual damages or declare an
      Event
      of Default pursuant to Section
      2
      herein
      for the Obligor 's failure to deliver certificates representing shares of Common
      Stock upon conversion within the period specified herein and such Holder shall
      have the right to pursue all remedies available to it at law or in equity
      including, without limitation, a decree of specific performance and/or
      injunctive relief, in each case without the need to post a bond or provide
      other
      security. The exercise of any such rights shall not prohibit the Holder from
      seeking to enforce damages pursuant to any other Section hereof or under
      applicable law.

    (v) In
      addition to any other rights available to the Holder, if the Obligor fails
      to
      deliver to the Holder such certificate or certificates pursuant to Section
      3(a)(i) by
      the
      fifth (5th)
      Trading
      Day after the Conversion Date, and if after such fifth (5th)
      Trading
      Day the Holder purchases (in an open market transaction or otherwise) Common
      Stock to deliver in satisfaction of a sale by such Holder of the Underlying
      Shares which the Holder anticipated receiving upon such conversion (a
“Buy-In”),
      then
      the Obligor shall (A) pay in cash to the Holder (in addition to any remedies
      available to or elected by the Holder) the amount by which (x) the Holder's
      total purchase price (including brokerage commissions, if any) for the Common
      Stock so purchased exceeds (y) the product of (1) the aggregate number of shares
      of Common Stock that such Holder anticipated receiving from the conversion
      at
      issue multiplied by (2) the market price of the Common Stock at the time of
      the
      sale giving rise to such purchase obligation and (B) at the option of the
      Holder, either reissue a Debenture in the principal amount equal to the
      principal amount of the attempted conversion or deliver to the Holder the number
      of shares of Common Stock that would have been issued had the Obligor timely
      complied with its delivery requirements under Section
      3(a)(i).
      For
      example, if the Holder purchases Common Stock having a total purchase price
      of
      $11,000 to cover a Buy-In with respect to an attempted conversion of Debentures
      with respect to which the market price of the Underlying Shares on the date
      of
      conversion was a total of $10,000 under clause (A) of the immediately preceding
      sentence, the Obligor shall be required to pay the Holder $1,000. The Holder
      shall provide the Obligor written notice indicating the amounts payable to
      the
      Holder in respect of the Buy-In.

      or
      otherwise. Without the Holder’s consent, the Obligor will not and will not
      permit any of their subsidiaries to, directly or indirectly, enter into, create,
      incur, assume or suffer to exist any indebtedness of any kind, on or with

      the
      State of New Jersey, without giving effect to conflicts of laws thereof. Each
      of
      the parties consents to the jurisdiction of the Superior Courts of the State
      of
      New Jersey sitting in Hudson County, New Jersey and the U.S. District Court
      for the District of New Jersey sitting in Newark, New Jersey in connection
      with
      any dispute arising under this Debenture and hereby waives, to the maximum

      in
      connection with the rendering of legal advice as to the Holder’s rights,
      remedies and obligations, (ii) collecting any sums which become due to the
      Holder, (iii) defending or prosecuting any proceeding or any counterclaim to

    Section
      12. Any
      waiver by the Holder of a breach of any provision of this Debenture shall not
      operate as or be construed to be a waiver of any other breach of such provision
      or of any breach of any other provision of this Debenture. The failure of the
      Holder to insist upon strict adherence to any term of this Debenture on one
      or
      more occasions shall not be considered a waiver or deprive that party of the
      right thereafter to insist upon strict adherence to that term or any other
      term
      of this Debenture. Any waiver must be in writing.

     

    Section
      13. If
      any
      provision of this Debenture is invalid, illegal or unenforceable, the balance
      of
      this Debenture shall remain in effect, and if any provision is inapplicable
      to
      any person or circumstance, it shall nevertheless remain applicable to all
      other
      persons and circumstances. If it shall be found that any interest or other
      amount deemed interest due hereunder shall violate applicable laws governing
      usury, the applicable rate of interest due hereunder shall automatically be
      lowered to equal the maximum permitted rate of interest. The Obligor covenants
      (to the extent that it may lawfully do so) that it shall not at any time insist
      upon, plead, or in any manner whatsoever claim or take the benefit or advantage
      of, any stay, extension or usury law or other law which would prohibit or
      forgive the Obligor from paying all or any portion of the principal of or
      interest on this Debenture as contemplated herein, wherever enacted, now or
      at
      any time hereafter in force, or which may affect the covenants or the
      performance of this indenture, and the Obligor (to the extent it may lawfully
      do
      so) hereby expressly waives all benefits or advantage of any such law, and
      covenants that it will not, by resort to any such law, hinder, delay or impeded
      the execution of any power herein granted to the Holder, but will suffer and
      permit the execution of every such as though no such law has been
      enacted.

     

    Section
      14. Whenever
      any payment or other obligation hereunder shall be due on a day other than
      a
      Business Day, such payment shall be made on the next succeeding Business
      Day.

     

    Section
      15. THE
      PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT ANY
      OF
      THEM MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON
      OR
      ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY TRANSACTION
      DOCUMENT OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL
      OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS PROVISION IS A MATERIAL INDUCEMENT
      FOR
      THE PARTIES’ ACCEPTANCE OF THIS AGREEMENT.

    FOR
      VALUE

      terms used herein without definition shall have the meanings ascribed to such
      terms in that certain Securities Purchase Agreement dated as of December 28,
      2005, between Borrower and the Holder (as amended, modified or supplemented
      from

    The
      following terms shall apply to this Debenture:

     

    ARTICLE
      I

    INTEREST
      & AMORTIZATION

     

    1.1.  Contract
      Rate.
      Subject
      to Sections 4.11 and 6.7 hereof, interest payable on this Debenture shall accrue
      at a rate per annum equal to seven and one-half percent (7.5%) (the
“Contract
      Rate”).
      

     

    1.2.  Payments.
      Payment
      of the aggregate principal amount outstanding under this Debenture (the

    ARTICLE
      II

    CONVERSION
      REPAYMENT 

     

    2.1.  Optional
      Conversion.
      Subject
      to the terms of this Article II, the Holder shall have the right, but not the
      obligation, at any time until the Maturity Date, or thereafter during an Event
      of Default and to convert all or any portion of the outstanding Principal Amount
      and/or accrued interest and fees due and payable into fully paid and
      nonassessable shares of the Common Stock at the Fixed Conversion Price. The
      shares of Common Stock to be issued upon such conversion are herein referred
      to
      as the “Conversion
      Shares.”
The
      “Fixed
      Conversion Price”
shall
      mean $4.00.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    2.2.  Conversion
      Limitation.
      Notwithstanding anything contained herein to the contrary, the Holder shall
      not
      be entitled to convert pursuant to the terms of this Debenture an amount that
      would be convertible into that number of Conversion Shares which would exceed
      the difference between the number of shares of Common Stock beneficially owned
      by such Holder or issuable upon exercise of the warrant and the option held
      by
      such Holder and 4.99% of the outstanding shares of Common Stock of Borrower.
      For
      the purposes of the immediately preceding sentence, beneficial ownership shall
      be determined in accordance with Section 13(d) of the Exchange Act and
      Regulation 13d-3 thereunder. The Conversion Shares limitation described in
      this
      Section 3.2 shall automatically become null and void without any notice to
      any
      Borrower upon the occurrence and during the continuance beyond any applicable
      grace period of an Event of Default, or upon 65 days prior notice to
      Borrower.

     

    2.3.  Mechanics
      of Holder’s Conversion.
      In the
      event that the Holder elects to convert this Debenture into Common Stock, the
      Holder shall give notice of such election by delivering an executed and
      completed notice of conversion (“Notice
      of Conversion”)
      to
      Borrower and such Notice of Conversion shall provide a breakdown in reasonable
      detail of the Principal Amount, accrued interest and fees that are being
      converted. On each Conversion Date (as hereinafter defined) and in accordance
      with its Notice of Conversion, the Holder shall make the appropriate reduction
      to the Principal Amount, accrued interest and fees as entered in its records
      and
      shall provide written notice thereof to the Borrower on the Conversion Date.
      Each date on which a Notice of Conversion is delivered or telecopied to Borrower
      in accordance with the provisions hereof shall be deemed a Conversion Date
      (the
“Conversion
      Date”).
      A
      form of Notice of Conversion to be employed by the Holder is annexed hereto
      as
Exhibit
      A.
      Pursuant to the terms of the Notice of Conversion, Borrower will issue
      instructions to the transfer agent accompanied by an opinion of counsel to
      Borrower of the Notice of Conversion and shall cause the transfer agent to
      transmit the certificates representing the Conversion Shares to the Holder
      by
      physical delivery or crediting the account of the Holder’s designated broker
      with the Depository Trust Corporation (“DTC”)
      through its Deposit Withdrawal Agent Commission (“DWAC”)
      system
      within three (3) business days after receipt by Borrower of the Notice of
      Conversion (the “Delivery
      Date”).
      In
      the case of the exercise of the conversion rights set forth herein the
      conversion privilege shall be deemed to have been exercised and the Conversion
      Shares issuable upon such conversion shall be deemed to have been issued upon
      the date of receipt by Borrower of the Notice of Conversion. The Holder shall
      be
      treated for all purposes as the record holder of such Common Stock, unless
      the
      Holder provides Borrower written instructions to the contrary.Late
      Payments.
      Each
      Borrower understands that a delay in the delivery of the shares of Common Stock
      in the form required pursuant to this Article beyond the Delivery Date could
      result in economic loss to the Holder. As compensation to the Holder for such
      loss, the each Borrower agrees to jointly and severally pay late payments to
      the
      Holder for late issuance of such shares in the form required pursuant to this
      Article II upon conversion of the Debenture, in the amount equal to $500 per
      business day after the Delivery Date. Each Borrower shall pay any payments
      incurred under this Section in immediately available funds upon demand.

    2.4.  Conversion
      Mechanics.

     

    (a)  The
      number of shares of Common Stock to be issued upon each conversion of this
      Debenture shall be determined by dividing that portion of the principal and
      interest and fees to be converted, if any, by the then applicable Fixed
      Conversion Price. 

     

    (b)  The
      Fixed
      Conversion Price and number and kind of shares or other securities to be issued
      upon conversion shall be subject to adjustment from time to time upon the
      happening of certain events while this conversion right remains outstanding,
      as
      follows:

     

    A.  Reclassification,
      etc.
      If
      Borrower at any time shall, by reclassification or otherwise, change the Common
      Stock into the same or a different number of securities of any class or classes,
      this Debenture, as to the unpaid Principal Amount and accrued interest thereon,
      shall thereafter be deemed to evidence the right to purchase an adjusted number
      of such securities and kind of securities as would have been issuable as the
      result of such change with respect to the Common Stock (i) immediately prior
      to
      or (ii) immediately after such reclassification or other change at the sole
      election of the Holder.

     

    B.  Stock
      Splits, Combinations and Dividends.
      If the
      shares of Common Stock are subdivided or combined into a greater or smaller
      number of shares of Common Stock, or if a dividend is paid on the Common Stock
      or any preferred stock issued by Borrower in shares of Common Stock, the Fixed
      Conversion Price shall be proportionately reduced in case of subdivision of
      shares or stock dividend or proportionately increased in the case of combination
      of shares, in each such case by the ratio which the total number of shares
      of
      Common Stock outstanding immediately after such event bears to the total number
      of shares of Common Stock outstanding immediately prior to such
      event.

     

    2.5.  Reservation
      of Shares.
      During
      the period the conversion right exists, Borrower will reserve from its
      authorized and unissued Common Stock a sufficient number of shares to provide
      for the issuance of Common Stock upon the full conversion of this Debenture.
      Borrower represents that upon issuance, such shares will be duly and validly
      issued, fully paid and non-assessable. Borrower agrees that its issuance of
      this
      Debenture shall constitute full authority to its officers, agents, and transfer
      agents who are charged with the duty of executing and issuing stock certificates
      to execute and issue the necessary certificates for shares of Common Stock
      upon
      the conversion of this Debenture.

     

    2.6.  Registration
      Rights.
      The
      Holder has been granted registration rights with respect to the shares of Common
      Stock issuable upon conversion of this Debenture as more fully set forth in
      a
      Registration Rights Agreement dated as of the date hereof between Borrower
      and
      the Holder.

    2.7.  Issuance
      of New Debenture.
      Upon
      any partial conversion of this Debenture, a new Debenture containing the same
      date and provisions of this Debenture shall, at the request of the Holder,
      be
      issued by the Borrower to the Holder for the principal balance of this Debenture
      and interest which shall not have been converted or paid. Subject to the
      provisions of Article III, the Borrower will pay no costs, fees or any other
      consideration to the Holder for the production and issuance of a new
      Debenture.
