event for any reason, any payment by or act of the Company or the Holder shall
result in payment of interest which would exceed the limit authorized by or be
in violation of the law of the jurisdiction applicable to this Note, then
ipso facto the obligation of the Company to pay interest or perform such
act or requirement shall be reduced to the limit authorized under such law, so
that in no event shall the Company be obligated to pay any such interest,
perform any such act or be bound by any requirement which would result in the
payment of interest in excess of the limit so authorized. In the event any
payment by or act of the Company shall result in the extraction of a rate of
interest in excess of a sum which is lawfully collectible as interest, then such
amount (to the extent of such excess not returned to the Company) shall, without
further agreement or notice between or by the Company or the Holder, be deemed
applied to the payment of principal, if any, hereunder immediately upon receipt
of such excess funds by the Holder, with the same force and effect as though the
Company had specifically designated such sums to be so applied to principal and
the Holder had agreed to accept such sums as an interest-free prepayment of this
Note. If any part of such excess remains after the principal has been paid in
full, whether by the provisions of the preceding sentences of this Section or
otherwise, such excess shall be deemed to be an interest-free loan from the
Company to the Holder, which loan shall be payable immediately upon demand by
the Company. The provisions of this Section shall control every other provision
of this Note.

Signature

     To evidence the binding effect of
the foregoing provisions, the Company has caused this instrument to be duly
executed by an officer thereunto duly authorized as of, but not necessarily on,
the date first above written.

officers, or the Company’s legal counsel or advisors for investment, legal or
tax advice, including advice with respect to the hold periods and resale
restrictions imposed upon the Note by the securities legislation in the
jurisdiction in which the Investor resides, and has, if desired, in all cases
sought the advice of the Investor’s own personal investment advisor, legal
counsel and tax advisors, and the Investor is either experienced in or
knowledgeable with regard to the affairs of the Company or, either alone or with
its professional advisors, is capable by reason of knowledge and experience in
financial and business matters in general, and investments in particular, of
evaluating the merits and risks of an investment in the Note, and it is able to
bear the economic risk of an investment in the Note and can otherwise be
reasonably assumed to have the capacity to protect its own interest in

registration provisions of the 1933 Act or an exemption therefrom, and that all
offers and sales after the Distribution Compliance Period shall be made only in
compliance with the registration provisions of the 1933 Act or an exemption

provided, however, that the Company shall not disclose material nonpublic
information to the Investor, or to advisors to or representatives of the
Investor, unless prior to disclosure of such information the Company identifies
such information as being material nonpublic information and provides the
Investor, such advisors and representatives with the opportunity to accept or
refuse to accept such material nonpublic information for review and the Investor
wishing to obtain such information enters into an appropriate confidentiality
agreement with the Company with respect thereto.

     8. Survival and
Indemnification:

     (a)
Survival. The representations, warranties, covenants and agreements
contained in this Agreement shall survive the Closing of the transactions
contemplated by this Agreement until the repayment in full of the Note.

     (b)
Indemnification. The Company agrees to indemnify and hold harmless each
Investor and its Affiliates and their respective directors, officers, employees
and agents from and against any and all losses, claims, damages, liabilities and
expenses (including without limitation reasonable attorney fees and
disbursements and other expenses incurred in connection with investigating,
preparing or defending any action, claim or proceeding, pending or threatened
and the costs of enforcement thereof) (collectively, “Losses”) to which
such Person may become subject as a result of any breach of representation,
warranty, covenant or agreement made by or to be performed on the part of the
Company under the Transaction Documents, and will reimburse any such Person for
all such amounts as they are incurred by such Person.

     (c)
Conduct of Indemnification Proceedings. Promptly after receipt by a
Person (the “Indemnified Person”) of notice of any demand, claim or
circumstances which would or might give rise to a claim or the commencement of
any action, proceeding or investigation in respect of which indemnity may be
sought pursuant to Section 8(b), such Indemnified Person shall promptly notify
the Company in writing and the Company shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Person, and shall assume the payment of all fees and expenses; provided,
however, that the failure of any Indemnified Person so to notify the Company
shall not relieve the Company of its obligations hereunder except to the extent
that the Company is materially prejudiced by such failure to notify. In any such
proceeding, any Indemnified Person shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person unless: (i) the Company and the Indemnified Person shall
have mutually agreed to the retention of such counsel; or (ii) in the reasonable judgment of counsel to such
Indemnified Person representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. The
Company shall not be liable for any settlement of any proceeding effected
without its written consent, which consent shall not he unreasonably withheld,
but if settled with such consent, or if there be a final judgment for the
plaintiff, the Company shall indemnify and hold harmless such Indemnified Person
from and against any loss or liability (to the extent stated above) by reason of
such settlement or judgment. Without the prior written consent of the
Indemnified Person, which consent shall not be unreasonably withheld, the
Company shall not effect any settlement of any pending or threatened proceeding
in respect of which any Indemnified Person is or could have been a party and
indemnity could have been sought hereunder by such Indemnified Party, unless
such settlement includes an unconditional release of such Indemnified Person
from all liability arising out of such proceeding.

provision of this Agreement that is prohibited or unenforceable in any

enforceable to the maximum extent permitted by applicable law, and any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. To the extent
permitted by applicable law, the parties hereby waive any provision of law which
renders any provision hereof prohibited or unenforceable in any respect.
