      2. Guarantee. Each Guarantor hereby agrees as follows:

            (a) Guarantee.

                  (i) The Guarantors hereby, jointly and severally,
                  unconditionally and irrevocably, guarantee to the Purchasers
                  and their respective successors, endorsees, 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 Purchasers 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 Purchasers 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 Purchasers whole on a monetary basis for
                  the Company's failure to perform such Obligations in
                  accordance with the Transaction Documents.

                                       2

            (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 Purchasers, and each Guarantor shall remain liable to the
Purchasers for the full amount guaranteed by such Guarantor hereunder.

            (c) No Subrogation. Notwithstanding any payment made by any
Guarantor hereunder or any set-off or application of funds of any Guarantor by
the Purchasers, no Guarantor shall be entitled to be subrogated to any of the
rights of the Purchasers against the Company or any other Guarantor or any
collateral security or guarantee or right of offset held by the Purchasers 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 Purchasers 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 Purchasers,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Purchasers in the exact form received
by such Guarantor (duly indorsed by such Guarantor to the Purchasers, if
required), to be applied against the Obligations, whether matured or unmatured,
in such order as the Purchasers 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
Purchasers may be rescinded by the Purchasers 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 Purchasers, and the Purchase 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 Purchasers may deem advisable from time to time, and
any collateral security, guarantee or right of offset at any time held by the
Purchasers for the payment of the Obligations may be sold, exchanged, waived,
surrendered or released. The Purchasers 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.

                                       3

            (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 Purchasers 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 Purchasers, 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
Purchase 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 Purchasers, (b) any
defense, set-off or counterclaim (other than a defense of payment or performance
or fraud or misconduct by Purchasers) which may at any time be available to or
be asserted by the Company or any other Person against the Purchasers, 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
Purchasers may, but shall be under no obligation to, make a similar demand on or
otherwise pursue such rights and remedies as they 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 Purchasers 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
Purchasers against any Guarantor. For the purposes hereof, "demand" shall
include the commencement and continuance of any legal proceedings.

            (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 Purchasers 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 Purchasers without set-off or counterclaim in U.S.
dollars at the address set forth or referred to in the Purchase Agreement.

      3. Representations and Warranties. Each Guarantor hereby makes the
following representations and warranties to Purchasers as of the date hereof:

                                       4

            (a) Organization and Qualification. The Guarantor is a corporation,
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 Purchase 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").

            (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) Purchase Agreement. The representations and warranties of the
Company set forth in the Purchase 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
Purchase Agreement, and the Purchasers 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.

            (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.

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.

            (b) So long as any of the Obligations are outstanding, each
Guarantor will not directly or indirectly on or after the date of this
Guarantee:

                  (i) except with the prior written consent of the Agent (as
                  defined in the Security Agreement), enter into, create, incur,
                  assume or suffer to exist any indebtedness for borrowed money
                  of any kind, including but not limited to, a guarantee, on or
                  with respect to any of its property or assets now owned or
                  hereafter acquired or any interest therein or any income or
                  profits therefrom that is senior to, or pari passu with, in
                  any respect, such Guarantor's obligations hereunder;

                  (ii) enter into, create, incur, assume or suffer to exist any
                  liens of any kind, on or with respect to any of its property
                  or assets now owned or hereafter acquired or any interest
                  therein or any income or profits therefrom that is senior to,
                  in any respect, such Guarantor's obligations hereunder;

                  (iii) amend its certificate of incorporation, bylaws or other
                  charter documents so as to adversely affect any rights of the
                  Holder hereunder;

                  (iv) repay, repurchase or offer to repay, repurchase or
                  otherwise acquire more than a de minimis number of shares of
                  its Common Stock or Common Stock Equivalents;

                  (v) enter into any agreement with respect to any of the
                  foregoing; or

                  (vi) pay cash dividends on any equity securities of the
                  Company.

      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 Purchasers.

            (b) Notices. All notices, requests and demands to or upon the

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
Purchasers 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 Purchasers, 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 Purchasers of any right or remedy hereunder on any one occasion
shall not be construed as a bar to any right or remedy which the Purchasers
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 Purchasers
                  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
                  Purchasers.

                  (ii) Each Guarantor agrees to pay, and to save the Purchasers
                  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 Purchasers

                  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 Purchase Agreement.

                  (iv) The agreements in this Section shall survive repayment of
                  the Obligations and all other amounts payable under the
                  Purchase Agreement and the other Transaction Documents.

            (e) Successor and Assigns. This Guarantee shall be binding upon the
successors and assigns of each Guarantor and shall inure to the benefit of the
Purchasers and their 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 Purchasers.

            (f) Set-Off. Each Guarantor hereby irrevocably authorizes the
Purchasers 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 Purchasers to or for the credit or the account of such
Guarantor, or any part thereof in such amounts as the Purchasers may elect,
against and on account of the obligations and liabilities of such Guarantor to
the Purchasers hereunder and claims of every nature and description of the
Purchasers against such Guarantor, in any currency, whether arising hereunder,
under the Purchase Agreement, any other Transaction Document or otherwise, as
the Purchasers may elect, whether or not the Purchasers have made any demand for
payment and although such obligations, liabilities and claims may be contingent
or unmatured. The Purchasers shall notify such Guarantor promptly of any such
set-off and the application made by the Purchasers 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 Purchasers under this Section
are in addition to other rights and remedies(including, without limitation,
other rights of set-off) which the Purchasers 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.

            (i) Section Headings. The Section headings used in this Guarantee
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

            (j) Integration. This Guarantee and the other Transaction Documents
