      GUARANTEE, dated as of April 6, 2007, made by each of the signatories hereto

    WITNESSETH:
    WHEREAS,
      pursuant to that certain Loan Agreement, dated as of the date hereof, by and
      between the Company and the Lender (the “Loan

      Senior Secured Promissory Note, due April
      6,

      each Guarantor hereby agrees with the Lender as follows:

    2. Guarantee.
    (a) Guarantee.
    | (i) | The
                Guarantors hereby, jointly and severally, unconditionally and irrevocably,
                guarantee to the Lender and its respective successors, indorsees,
                transferees and assigns, the prompt and complete payment and performance
                by the Company when due (whether at the stated maturity, by acceleration
                or otherwise) of the Obligations.  | 
| (ii) | Anything
                herein or in any other Transaction Document to the contrary
                notwithstanding, the maximum liability of each Guarantor hereunder
                and
                under the other Transaction Documents shall in no event exceed the
                amount
                which can be guaranteed by such Guarantor under applicable federal
                and
                state laws, including laws relating to the insolvency of debtors,
                fraudulent conveyance or transfer or laws affecting the rights of
                creditors generally (after giving effect to the right of contribution
                established in Section 2(b)).  | 
| (iii) | Each
                Guarantor agrees that the Obligations may at any time and from time
                to
                time exceed the amount of the liability of such Guarantor hereunder
                without impairing the guarantee contained in this Section 2 or affecting
                the rights and remedies of the Lender
                hereunder. | 
| (iv) | The
                guarantee contained in this Section 2 shall remain in full force
                and
                effect until all the Obligations and the obligations of each Guarantor
                under the guarantee contained in this Section 2 shall have been satisfied
                by payment in full.  | 
| (v) | No
                payment made by the Company, any of the Guarantors, any other guarantor
                or
                any other Person or received or collected by the Lender from the
                Company,
                any of the Guarantors, any other guarantor or any other Person by
                virtue
                of any action or proceeding or any set-off or appropriation or application
                at any time or from time to time in reduction of or in payment of
                the
                Obligations shall be deemed to modify, reduce, release or otherwise
                affect
                the liability of any Guarantor hereunder which shall, notwithstanding
                any
                such payment (other than any payment made by such Guarantor in respect
                of
                the Obligations or any payment received or collected from such Guarantor
                in respect of the Obligations), remain liable for the Obligations
                up to
                the maximum liability of such Guarantor hereunder until the Obligations
                are paid in full. | 
| (vi) | Notwithstanding
                anything to the contrary in this Agreement, with respect to any defaulted
                non-monetary Obligations the specific performance of which by the
                Guarantors is not reasonably possible (e.g. the issuance of the Company's
                Common Stock), the Guarantors shall only be liable for making the
                Lender
                whole on a monetary basis for the Company's failure to perform such
                Obligations in accordance with the Transaction Documents.
                 | 
(b) Right
      of Contribution.
      Each
      Guarantor hereby agrees that to the extent that a Guarantor shall have paid
      more
      than its proportionate share of any payment made hereunder, such Guarantor
      shall
      be entitled to seek and receive contribution from and against any other
      Guarantor hereunder which has not paid its proportionate share of such payment.
      Each Guarantor's right of contribution shall be subject to the terms and
      conditions of Section 2(c). The provisions of this Section 2(b) shall in no
      respect limit the obligations and liabilities of any Guarantor to the Lender,
      and each Guarantor shall remain liable to the Lender for the full amount
      guaranteed by such Guarantor hereunder.
    2
          of 13
        (c) No
      Subrogation.
      Notwithstanding any payment made by any Guarantor hereunder or any set-off
      or
      application of funds of any Guarantor by the Lender, no Guarantor shall be
      entitled to be subrogated to any of the rights of the Lender against the Company
      or any other Guarantor or any collateral security or guarantee or right of
      offset held by the Lender for the payment of the Obligations, nor shall any
      Guarantor seek or be entitled to seek any contribution or reimbursement from
      the
      Company or any other Guarantor in respect of payments made by such Guarantor
      hereunder, until all amounts owing to the Lender by the Company on account
      of
      the Obligations are paid in full. If any amount shall be paid to any Guarantor
      on account of such subrogation rights at any time when all of the Obligations
      shall not have been paid in full, such amount shall be held by such Guarantor
      in
      trust for the Lender, segregated from other funds of such Guarantor, and shall,
      forthwith upon receipt by such Guarantor, be turned over to the Lender in the
      exact form received by such Guarantor (duly indorsed by such Guarantor to the
      Lender if required), to be applied against the Obligations, whether matured
      or
      unmatured, in such order as the Lender may determine.
    (d) Amendments,
      Etc. With Respect to the Obligations.
      Each
      Guarantor shall remain obligated hereunder notwithstanding that, without any
      reservation of rights against any Guarantor and without notice to or further
      assent by any Guarantor, any demand for payment of any of the Obligations made
      by the Lender may be rescinded by the Lender and any of the Obligations
      continued, and the Obligations, or the liability of any other Person upon or
      for
      any part thereof, or any collateral security or guarantee therefor or right
      of
      offset with respect thereto, may, from time to time, in whole or in part, be
      renewed, extended, amended, modified, accelerated, compromised, waived,
      surrendered or released by the Lender, and the Loan Agreement and the other
      Transaction Documents and any other documents executed and delivered in
      connection therewith may be amended, modified, supplemented or terminated,
      in
      whole or in part, as the Lender may deem advisable from time to time, and any
      collateral security, guarantee or right of offset at any time held by the Lender
      for the payment of the Obligations may be sold, exchanged, waived, surrendered
      or released. The Lender shall have no obligation to protect, secure, perfect
      or
      insure any Lien at any time held by them as security for the Obligations or
      for
      the guarantee contained in this Section 2 or any property subject thereto.
      
    (e) Guarantee
      Absolute and Unconditional.
      Each
      Guarantor waives any and all notice of the creation, renewal, extension or
      accrual of any of the Obligations and notice of or proof of reliance by the
      Lender upon the guarantee contained in this Section 2 or acceptance of the
      guarantee contained in this Section 2; the Obligations, and any of them, shall
      conclusively be deemed to have been created, contracted or incurred, or renewed,
      extended, amended or waived, in reliance upon the guarantee contained in this
      Section 2; and all dealings between the Company and any of the Guarantors,
      on
      the one hand, and the Lender, on the other hand, likewise shall be conclusively
      presumed to have been had or consummated in reliance upon the guarantee
      contained in this Section 2. Each Guarantor waives to the extent permitted
      by
      law diligence, presentment,
      protest, demand for payment and notice of default or nonpayment to or upon
      the
      Company or any of the Guarantors with respect to the Obligations. Each Guarantor
      understands and agrees that the guarantee contained in this Section 2 shall
      be
      construed as a continuing, absolute and unconditional guarantee of payment
      without regard to (a) the validity or enforceability of the Loan Agreement
      or
      any other Transaction Document, any of the Obligations or any other collateral
      security therefor or guarantee or right of offset with respect thereto at any
      time or from time to time held by the Lender, (b) any defense, set-off or
      counterclaim (other than a defense of payment or performance or fraud or
      misconduct by Lender) which may at any time be available to or be asserted
      by
      the Company or any other Person against the Lender, or (c) any other
      circumstance whatsoever (with or without notice to or knowledge of the Company
      or such Guarantor) which constitutes, or might be construed to constitute,
      an
      equitable or legal discharge of the Company for the Obligations, or of such
      Guarantor under the guarantee contained in this Section 2, in bankruptcy or
      in
      any other instance. When making any demand hereunder or otherwise pursuing
      its
      rights and remedies hereunder against any Guarantor, the Lender may, but shall
      be under no obligation to, make a similar demand on or otherwise pursue such
      rights and remedies as it may have against the Company, any other Guarantor
      or
      any other Person or against any collateral security or guarantee for the
      Obligations or any right of offset with respect thereto, and any failure by
      the
      Lender to make any such demand, to pursue such other rights or remedies or
      to
      collect any payments from the Company, any other Guarantor or any other Person
      or to realize upon any such collateral security or guarantee or to exercise
      any
      such right of offset, or any release of the Company, any other Guarantor or
      any
      other Person or any such collateral security, guarantee or right of offset,
      shall not relieve any Guarantor of any obligation or liability hereunder, and
      shall not impair or affect the rights and remedies, whether express, implied
      or
      available as a matter of law, of the Lender against any Guarantor. For the
      purposes hereof, "demand" shall include the commencement and continuance of
      any
      legal proceedings.
    3
          of 13
        (f) Reinstatement.
      The
      guarantee contained in this Section 2 shall continue to be effective, or be
      reinstated, as the case may be, if at any time payment, or any part thereof,
      of
      any of the Obligations is rescinded or must otherwise be restored or returned
      by
      the Lender upon the insolvency, bankruptcy, dissolution, liquidation or
      reorganization of the Company or any Guarantor, or upon or as a result of the
      appointment of a receiver, intervenor or conservator of, or trustee or similar
      officer for, the Company or any Guarantor or any substantial part of its
      property, or otherwise, all as though such payments had not been
      made.
    (g) Payments.
      Each
      Guarantor hereby guarantees that payments hereunder will be paid to the Lender
      without set-off or counterclaim in U.S. dollars at the address set forth or
      referred to in the Loan Agreement.
    3. Representations
      and Warranties.
      Each
      Guarantor hereby makes the following representations and warranties to Lender
      as
      of the date hereof:
    (a) Organization
      and Qualification.
      The
      Guarantor is a corporation or limited liability company, duly incorporated,
      validly existing and in good standing under the laws of the applicable
      jurisdiction set forth on Schedule 1, with the requisite corporate power and
      authority to own and use its properties and assets and to carry on its business
      as currently conducted. The Guarantor has no subsidiaries other than those
      identified as such on the Disclosure Schedules to the Loan Agreement. The
      Guarantor is duly qualified to do business and is in good standing as a foreign
      corporation in each jurisdiction in which the nature of the business conducted
      or property owned by it makes such qualification necessary, except where the
      failure to be so qualified or in good standing, as the case may be, could not,
      individually or in the aggregate, (x) adversely affect the legality, validity
      or
      enforceability of any of this Guaranty in any material respect, (y) have a
      material adverse effect on the results of operations, assets, prospects, or
      financial condition of the Guarantor or (z) adversely impair in any material
      respect the Guarantor's ability to perform fully on a timely basis its
      obligations under this Guaranty (a "Material
      Adverse Effect").
    4
          of 13
        (b) Authorization;
      Enforcement.
      The
      Guarantor has the requisite corporate power and authority to enter into and
      to
      consummate the transactions contemplated by this Guaranty, and otherwise to
      carry out its obligations hereunder. The execution and delivery of this Guaranty
      by the Guarantor and the consummation by it of the transactions contemplated
      hereby have been duly authorized by all requisite corporate action on the part
      of the Guarantor. This Guaranty has been duly executed and delivered by the
      Guarantor and constitutes the valid and binding obligation of the Guarantor
      enforceable against the Guarantor in accordance with its terms, except as such
      enforceability may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium, liquidation or similar laws relating to, or
      affecting generally the enforcement of, creditors' rights and remedies or by
      other equitable principles of general application.
    (c) No
      Conflicts.
      The
      execution, delivery and performance of this Guaranty by the Guarantor and the
      consummation by the Guarantor of the transactions contemplated thereby do not
      and will not (i) conflict with or violate any provision of its Certificate
      of
      Incorporation or By-laws or (ii) conflict with, constitute a default (or an
      event which with notice or lapse of time or both would become a default) under,
      or give to others any rights of termination, amendment, acceleration or
      cancellation of, any agreement, indenture or instrument to which the Guarantor
      is a party, or (iii) result in a violation of any law, rule, regulation, order,
      judgment, injunction, decree or other restriction of any court or governmental
      authority to which the Guarantor is subject (including Federal and state
      securities laws and regulations), or by which any material property or asset
      of
      the Guarantor is bound or affected, except in the case of each of clauses (ii)
      and (iii), such conflicts, defaults, terminations, amendments, accelerations,
      cancellations and violations as could not, individually or in the aggregate,
      have or result in a Material Adverse Effect. The business of the Guarantor
      is
      not being conducted in violation of any law, ordinance or regulation of any
      governmental authority, except for violations which, individually or in the
      aggregate, do not have a Material Adverse Effect.
    (d) Consents
      and Approvals.
      The
      Guarantor is not required to obtain any consent, waiver, authorization or order
      of, or make any filing or registration with, any court or other federal, state,
      local, foreign or other governmental authority or other person in connection
      with the execution, delivery and performance by the Guarantor of this
      Guaranty.
    (e) Loan
      Agreement.
      The
      representations and warranties of the Company set forth in the Loan Agreement
      as
      they relate to such Guarantor, each of which is hereby incorporated herein
      by
      reference, are true and correct as of each time such representations are deemed
      to be made pursuant to such Loan Agreement, and the Lender shall be entitled
      to
      rely on each of them as if they were fully set forth herein, provided, that
      each
      reference in each such representation and warranty to the Company's knowledge
      shall, for the purposes of this Section 3, be deemed to be a reference to such
      Guarantor's knowledge. 
    5
          of 13
        (f) Foreign
      Law.
      Each
      Guarantor has consulted with appropriate foreign legal counsel with respect
      to
      any of the above representations for which non-U.S. law is applicable. Such
      foreign counsel have advised each applicable Guarantor that such counsel knows
      of no reason why any of the above representations would not be true and
      accurate. Such foreign counsel were provided with copies of this Subsidiary
      Guarantee and the Transaction Documents prior to rendering their advice.
    4. Covenants.
      Each
      Guarantor covenants and agrees with the Lender that, from and after the date
      of
      this Guarantee until the Obligations shall have been paid in full, such
      Guarantor shall take, and/or shall refrain from taking, as the case may be,
      each
      commercially reasonable action that is necessary to be taken or not taken,
      as
      the case may be, so that no Event of Default is caused by the failure to take
      such action or to refrain from taking such action by such Guarantor.
    5. Miscellaneous.
    (a) Amendments
      in Writing.
      None of
      the terms or provisions of this Guarantee may be waived, amended, supplemented
      or otherwise modified except in writing by the majority in interest (based
      on
      the then-outstanding principal amount of the Note at the time of such
      determination) of the Lender.
    (b) Notices.
      All
      notices, requests and demands to or upon the Lender or any Guarantor hereunder
      shall be effected in the manner provided for in the Loan Agreement; provided
      that any
      such notice, request or demand to or upon any Guarantor shall be addressed
      to
      such Guarantor at its notice address set forth on Schedule
      5(b).
    (c) No
      Waiver By Course Of Conduct; Cumulative Remedies.
      The
      Lender shall not by any act (except by a written instrument pursuant to Section
      5(a)), delay, indulgence, omission or otherwise be deemed to have waived any
      right or remedy hereunder or to have acquiesced in any default under the
      Transaction Documents or Event of Default. No failure to exercise, nor any
      delay
      in exercising, on the part of the Lender, any right, power or privilege
      hereunder shall operate as a waiver thereof. No single or partial exercise
      of
      any right, power or privilege hereunder shall preclude any other or further
      exercise thereof or the exercise of any other right, power or privilege. A
      waiver by the Lender of any right or remedy hereunder on any one occasion shall
      not be construed as a bar to any right or remedy which the Lender would
      otherwise have on any future occasion. The rights and remedies herein provided
      are cumulative, may be exercised singly or concurrently and are not exclusive
      of
      any other rights or remedies provided by law.
    (d) Enforcement
      Expenses;
      Indemnification.
    | (i) | Each
                Guarantor agrees to pay, or reimburse the Lender for, all its costs
                and
                expenses incurred in collecting against such Guarantor under the
                guarantee
                contained in Section 2 or otherwise enforcing or preserving any rights
                under this Guarantee and the other Transaction Documents to which
                such
                Guarantor is a party, including, without limitation, the reasonable
                fees
                and disbursements of counsel to the
                Lender. | 
6
          of 13
        | (ii) | Each
                Guarantor agrees to pay, and to save the Lender harmless from, any
                and all
                liabilities with respect to, or resulting from any delay in paying,
                any
                and all stamp, excise, sales or other taxes which may be payable
                or
                determined to be payable in connection with any of the transactions
                contemplated by this Guarantee. | 
| (iii) | Each
                Guarantor agrees to pay, and to save the Lender harmless from, any
                and all
                liabilities, obligations, losses, damages, penalties, actions, judgments,
                suits, costs, expenses or disbursements of any kind or nature whatsoever
                with respect to the execution, delivery, enforcement, performance
                and
                administration of this Guarantee to the extent the Company would
                be
                required to do so pursuant to the Loan
                Agreement. | 
| (iv) | The
                agreements in this Section shall survive repayment of the Obligations
                and
                all other amounts payable under the Loan Agreement and the other
                Transaction Documents.  | 
(e) Successor
      and Assigns.
      This
      Guarantee shall be binding upon the successors and permitted assigns of each
      Guarantor and shall inure to the benefit of the Lender and its respective
      successors and assigns; provided that no Guarantor may assign, transfer or
      delegate any of its rights or obligations under this Guarantee without the
      prior
      written consent of the Lender.
    (f) Set-Off.
      Each
      Guarantor hereby irrevocably authorizes the Lender at any time and from time
      to
      time while an Event of Default under any of the Transaction Documents shall
      have
      occurred and be continuing, without notice to such Guarantor or any other
      Guarantor, any such notice being expressly waived by each Guarantor, to set-off
      and appropriate and apply any and all deposits, credits, indebtedness or claims,
      in any currency, in each case whether direct or indirect, absolute or
      contingent, matured or unmatured, at any time held or owing by the Lender to
      or
      for the credit or the account of such Guarantor, or any part thereof in such
      amounts as the Lender may elect, against and on account of the obligations
      and
      liabilities of such Guarantor to the Lender hereunder and claims of every nature
      and description of the Lender against such Guarantor, in any currency, whether
      arising hereunder, under the Loan Agreement, any other Transaction Document
      or
      otherwise, as the Lender may elect, whether or not the Lender has made any
      demand for payment and although such obligations, liabilities and claims may
      be
      contingent or unmatured. The Lender shall notify such Guarantor promptly of
      any
      such set-off and the application made by the Lender of the proceeds thereof,
      provided that the failure to give such notice shall not affect the validity
      of
      such set-off and application. The rights of the Lender under this Section are
      in
      addition to other rights and remedies (including, without limitation, other
      rights of set-off) which the Lender may have.
    (g) Counterparts.
      This
      Guarantee may be executed by one or more of the parties to this Guarantee on
      any
      number of separate counterparts (including by telecopy), and all of said
      counterparts taken together shall be deemed to constitute one and the same
      instrument. 
    (h) Severability.
      Any
      provision of this Guarantee which is prohibited or unenforceable in any
      jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
      such prohibition or unenforceability without invalidating the remaining
      provisions hereof, and any such prohibition or unenforceability in any
      jurisdiction shall not invalidate or render unenforceable such provision in
      any
      other jurisdiction.

                or for recognition and enforcement of any judgment in respect thereof,
                to
                the non-exclusive general jurisdiction of the Courts of the State

| (iv) | agrees
                that nothing herein shall affect the right to effect service of process
                in
                any other manner permitted by law or shall limit the right to ▇▇▇

                other jurisdiction; and  | 
| (v) | waives,
                to the maximum extent not prohibited by law, any right it may have
                to
                claim or recover in any legal action or proceeding referred to in
