    3. RIGHTS
      UPON EVENT OF DEFAULT.

     

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

     

    (i) the
      Company’s failure to pay to the Holder any amount of Principal, , Interest, or
      other amounts when and as due under this Note or any other Transaction Document
      (as defined in the Note Purchase Agreement) or any other agreement, document,
      certificate or other instrument delivered in connection with the transactions
      contemplated hereby and thereby to which the Holder is a party;

     

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

     

    (iii) a
      court
      of competent jurisdiction enters an order or decree under any Bankruptcy Law
      that (A) is for relief against the Company or any of its Subsidiaries in an
      involuntary case, (B) appoints a Custodian of the Company or any of its
      Subsidiaries or (C) orders the liquidation of the Company or any of its
      Subsidiaries.

     

    (b) In
      the
      event an Event of Default occurs under Section 3(a)(i), the Interest shall
      be
      increased to eighteen percent (18.0%) 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.

     

    (c) In
      the
      event an Event of Default occurs under Sections 3(a)(ii) and 3(a)(iii), the
      Company shall within four (4) Business Days 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
      Required Holders 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 outstanding
      principal and accrued Interest (including any increased interest pursuant to
      Section 3(b)above) (the “Redemption
      Amount”)
      of
      this Note the Required Holders are electing to require the Company to redeem.
      Each portion of this Note subject to redemption by the Company pursuant to
      this
      Section 3(c) shall be redeemed by the Company at the Redemption Amount. To
      the
      extent redemptions required by this Section 3(c) 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 3(c), 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.

      Company hereby covenants and agrees that the Company will not, by amendment
      of
      its Articles 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

      the
      State of Nevada, and as expressly provided in this Note.

      any kind) with any Affiliate, except in the ordinary course of business in
      a
      manner and to an extent consistent with past practice and necessary or desirable
      for the prudent operation of its business, for fair consideration and on terms
      no less favorable to it or its Subsidiaries than would be obtainable in a
      comparable arm’s length transaction with a Person that is not an Affiliate
      thereof.

    (e) Change
      in Nature of Business.
      The
      Company shall not make, or permit any of its Subsidiaries to make, any change
      in
      the nature of its business as described in the Company’s most recent annual
      report filed on Form 10-KSB with the SEC. The Company shall not modify its
      corporate structure or purpose.

     

    (f) Preservation
      of Existence, Etc.
      The
      Company shall maintain and preserve, and cause each of its Subsidiaries to
      maintain and preserve, its existence, rights and privileges, and become or
      remain, and cause each of its Subsidiaries to become or remain, duly qualified
      and in good standing in each jurisdiction in which the character of the
      properties owned or leased by it or in which the transaction of its business
      makes such qualification necessary.

     

    (g) Maintenance
      of Properties, Etc.
      The
      Company shall maintain and preserve, and cause each of its Subsidiaries to
      maintain and preserve, all of its properties which are necessary or useful
      in
      the proper conduct of its business in good working order and condition, ordinary
      wear and tear excepted, and comply, and cause each of its Subsidiaries to
      comply, at all times with the provisions of all leases to which it is a party
      as
      lessee or under which it occupies property, so as to prevent any loss or
      forfeiture thereof or thereunder.

     

    (h) Maintenance
      of Insurance.
      The
      Company shall maintain, and cause each of its Subsidiaries to maintain,
      insurance with responsible and reputable insurance companies or associations
      (including, without limitation, comprehensive general liability, hazard, rent
      and business interruption insurance) with respect to its properties (including
      all real properties leased or owned by it) and business, in such amounts and
      covering such risks as is required by any governmental authority having
      jurisdiction with respect thereto or as is carried generally in accordance
      with
      sound business practice by companies in similar businesses similarly situated
      and in any event in amount, adequacy and scope reasonably satisfactory to the
      Collateral Agent. All policies covering the Collateral are to be made payable
      to
      the Collateral Agent for the benefit of the Holders, as its interests may
      appear, in case of loss, under a standard non-contributory “lender” or “secured
      party” clause and are to contain such other provisions as the Collateral Agent
      may require to fully protect the Holders’ interest in the Collateral and to any
      payments to be made under such policies. All certificates of insurance are
      to be
      delivered to the Collateral Agent and the policies are to be premium prepaid,
      with the loss payable and additional insured endorsement in favor of the
      Collateral Agent and such other Persons as the Collateral Agent may designate
      from time to time, and shall provide for not less than 30 days’ prior written
      notice to the Collateral Agent of the exercise of any right of cancellation.
      If
      the Company or any of its Subsidiaries fails to maintain such insurance, the
      Collateral Agent may arrange for such insurance, but at the Company’s expense
      and without any responsibility on the Collateral Agent’s part for obtaining the
      insurance, the solvency of the insurance companies, the adequacy of the
      coverage, or the collection of claims. Upon the occurrence and during the
      continuance of an Event of Default, the Collateral Agent shall have the sole
      right, in the name of the Holders, the Company and its Subsidiaries, to file
      claims under any insurance policies, to receive, receipt and give acquittance
      for any payments that may be payable thereunder, and to execute any and all
      endorsements, receipts, releases, assignments, reassignments or other documents
      that may be necessary to effect the collection, compromise or settlement of
      any
      claims under any such insurance policies.

      notice of any change in the location of any Collateral (as defined in the
      Security Documents), (ii) advise the Collateral Agent promptly, in sufficient
      detail, of any material adverse change relating to the type, quantity or quality
      of the Collateral or the Lien granted thereon and (iii) execute and deliver,
      and
      cause each of its Subsidiaries to execute and deliver, to the Collateral Agent
      for the benefit of the Holders of the Senior Bonds from time to time, solely
      for
      the Collateral Agent’s convenience in maintaining a record of Collateral, such
      written statements and schedules as the Collateral Agent may reasonably require,
      designating, identifying or describing the Collateral.

     

    8. 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
      change or amendment to this Note. No consideration shall be offered or paid
      to
      any holder of Notes to amend or consent to a waiver or modification of the
      Notes
      unless the same consideration also is offered to all of the holders of
      Notes.

      Note may not be offered, sold, assigned or transferred by the Holder without

      Holder may request, representing the outstanding Principal being transferred
      by
      the Holder and, if less then the entire outstanding Principal is being

      representing the outstanding Principal not being transferred. The Holder and
      any
      assignee, by acceptance of this Note, acknowledge and agree that, by reason
      of
      the provisions of this Section 10(a), the outstanding Principal represented
      by this Note may be less than the Principal stated on the face of this
      Note.

     

    (b) Lost,
      Stolen or Mutilated Note.
      Upon
      receipt by the Company of evidence reasonably satisfactory to the Company of
      the
      loss, theft, destruction or mutilation of this Note, and, in the case of loss,
      theft or destruction, of any indemnification undertaking by the Holder to the
      Company in customary form and, in the case of mutilation, upon surrender and
      cancellation of this Note, the Company shall execute and deliver to the Holder
      a
      new Note (in accordance with Section 10(d)) representing the outstanding
      Principal.

     

    (c) Note
      Exchangeable for Different Denominations.
      This
      Note is exchangeable, upon the surrender hereof by the Holder at the principal
      office of the Company, for a new Note or Notes (in accordance with
      Section 10(d) and in principal amounts of at least $100,000) representing
      in the aggregate the outstanding Principal of this Note, and each such new
      Note
      will represent such portion of such outstanding Principal as is designated
      by
      the Holder at the time of such surrender.

      of
      this Note, such new Note (i) shall be of like tenor with this Note,
      (ii) shall represent, as indicated on the face of such new Note, the
      Principal remaining outstanding (or in the case of a new Note being issued
      pursuant to Section 10(a) or Section 10(c), the Principal designated
      by the Holder which, when added to the principal represented by the other new
      Notes issued in connection with such issuance, does not exceed the Principal
      remaining outstanding under this Note immediately prior to such issuance of
      new
      Notes), (iii) shall have an issuance date, as indicated on the face of such
      new Note, which is the same as the Issuance Date of this Note, (iv) shall have

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

      otherwise takes action to collect amounts due under this Note or to enforce
      the
      provisions of this Note or (b) there occurs any bankruptcy, reorganization,
      receivership of the Company or other proceedings affecting Company creditors’
rights and involving a claim under this Note, then the Company shall pay the
      costs incurred by the Required Holders for such collection, enforcement or
      action or in connection with such bankruptcy, reorganization, receivership
      or
      other proceeding, including, but not limited to, attorneys’ fees and
      disbursements.

      of, or affect the interpretation of, this Note.

      OR INDULGENCE NOT WAIVER.
      No
      failure or delay on the part of the Required Holders in the exercise of any
      power, right or privilege hereunder shall operate as a waiver thereof, nor

      Company in writing (which address, in the case of each of the Purchasers, shall
      initially be as set forth on the Schedule of Buyers attached to the Note
      Purchase Agreement); provided that the Holder may elect to receive a payment

      the

      of determining the amount of Interest due on such date. 

     

    16. CANCELLATION.

    17. WAIVER
      OF NOTICE.
      To the
      extent permitted by law, the Company hereby waives demand, notice, protest
      and
      all other demands and notices in connection with the delivery, acceptance,
      performance, default or enforcement of this Note and the Note Purchase
      Agreement.

     

    18. GOVERNING
      LAW, JURISDICTION; JURY TRIAL.
      This
      Note shall be construed and enforced in accordance with, and all questions
      concerning the construction, validity, interpretation and performance of this
      Note shall be governed by, the internal laws of the State of New York, without
      giving effect to any choice of law or conflict of law provision or rule (whether
      of the State of New York or any other jurisdictions) that would cause the
      application of the laws of any jurisdictions other than the State of New York.
      The Company hereby irrevocably submits to the exclusive jurisdiction of the
      state and federal courts sitting in The City of New York, Borough of Manhattan,
      for the adjudication of any dispute hereunder or in connection herewith or
      with
      any transaction contemplated hereby or discussed herein, and hereby irrevocably
      waives, and agrees not to assert in any suit, action or proceeding, any claim
      that it is not personally subject to the jurisdiction of any such court, that
      such suit, action or proceeding is brought in an inconvenient forum or that
      the
      venue of such suit, action or proceeding is improper. Nothing contained herein
      shall be deemed to limit in any way any right to serve process in any manner
      permitted by law. The Company hereby irrevocably waives personal service of
      process and consents to process being served in any such suit, action or
      proceeding by mailing a copy thereof to such party at the address as provided
      in
      Section 15 hereof and agrees that such service shall constitute good and
      sufficient service of process and notice thereof. Nothing contained herein
      shall
      be deemed or operate to preclude the Holder from bringing suit or taking other
      legal action against the Company in any other jurisdiction to collect on the
      Company’s obligations to the Holder, to realize on any collateral or any other
      security for such obligations, or to enforce a judgment or other court ruling
      in
      favor of the Holder. THE
      COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO
      REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN
      CONNECTION WITH OR ARISING OUT OF THIS NOTE OR ANY TRANSACTION CONTEMPLATED
      HEREBY.

    19. SEVERABILITY.
      If any
      provision of this Note is prohibited by law or otherwise determined to be
      invalid or unenforceable by a court of competent jurisdiction, the provision
      that would otherwise be prohibited, invalid or unenforceable shall be deemed
      amended to apply to the broadest extent that it would be valid and enforceable,
      and the invalidity or unenforceability of such provision shall not affect the
      validity of the remaining provisions of this Note so long as this Note as so
      modified continues to express, without material change, the original intentions
      of the parties as to the subject matter hereof and the prohibited nature,
      invalidity or unenforceability of the provision(s) in question does not
      substantially impair the respective expectations or reciprocal obligations
      of
      the parties or the practical realization of the benefits that would otherwise
      be
      conferred upon the parties. The parties will endeavor in good faith negotiations
      to replace the prohibited, invalid or unenforceable provision(s) with a valid
      provision(s), the effect of which comes as close as possible to that of the
      prohibited, invalid or unenforceable provision(s).
