                  Interest not paid when due shall thereafter bear like interest
                  as the principal, but unpaid interest so compounded shall not
                  exceed the maximum rate permitted by law.

         1.2      Terms of Payment. Principal and interest are due and payable
                  on March 1, 2007. The Company may, at its option, prepay all
                  or any amount owed prior to such date. Unless otherwise
                  specified by Lender, any such payment shall be credited to

                  not cured within three calendar days after written notice, (b)
                  the entry of a decree or order for relief in respect of the

                  constituted or hereafter amended, or any other applicable

                  appointing a receiver, trustee, or custodian of the Company or
                  for any substantial part of the Company's property, which
                  decree or order is not stayed or set aside within 60 days
                  thereafter, or (c) the filing by the Company of a petition,
                  answer or consent seeking relief under Title 11 of the United
                  States Code, as now constituted or hereafter amended, or the
                  consent by the Company to the institution of proceedings
                  thereunder or to the appointment of a receiver, trustee or
                  custodian.

2.       Attorneys' Fees. In the event any judicial proceedings are instituted
         to enforce or interpret the rights and obligations of the Company and
         the Lender under this Note, the prevailing party in such proceeding
         shall be entitled to reasonable attorneys' fees and costs, as well as
         related costs of collection and appeal.

3.       Governing Law. This Note and all transactions hereunder and/or
         evidenced hereby shall be governed by, construed under, and enforced in
         accordance with the laws of the State of California, without regard to
         any choice of law or conflict of law provisions thereof.

4.       Severability. Should any provision of this Note be declared or be
         determined by any court of competent jurisdiction to be invalid,
         illegal or unenforceable, such provision shall be severable from the
         remainder of this Note, and the legality, validity and enforceability
         of the remaining provisions shall not in any way be affected or

controlling CTA or any of its affiliates (CTA and each such person and entity
being referred to as an "Indemnified Person"), to the fullest extent legally
permissible from and against any and all losses, claims, damages or liabilities
or actions related to or arising out of this engagement or the role of CTA in
connection herewith, and will pay (or, if paid by an Indemnified Person,
reimburse such Indemnified Person) for all fees and expenses (including, without
limitation, reasonable attorneys' fees) incurred by such Indemnified Person in
connection with investigating, preparing or defending any such action or claim,
whether or not in connection with pending or threatened litigation in which any
Indemnified Person is a party. The Company will not, however, be responsible for
any claims, liabilities, losses, damages or expenses which result from any

                                      -3-

<PAGE>

compromise or settlement not approved by the Company or which result primarily
from the fraud, willful misconduct or gross negligence of any Indemnified
Person. The Company also agrees that no Indemnified Person shall have any
liability to the Company for or in connection with this engagement, except for
any such liability for losses, claims, damages, liabilities or expenses incurred
by the Company that results from the fraud, willful misconduct or gross
negligence of the Indemnified Person. The foregoing agreement shall be in
addition to any rights that either party may have at common law or otherwise,
including, without limitation, any right to contribution.

         If any action or proceeding is brought against any Indemnified Person
in respect of which indemnity may be sought against the Company pursuant hereto,
or if any Indemnified Person receives notice from any potential litigant or a
claimant which such person reasonable believes will result in the commencement
of any such action or proceeding, such indemnified Person shall promptly notify
the Company in writing of the commencement of such action or proceeding, or of
the existence of such claim. In case any such action or proceeding shall be
brought against any Indemnified Person, the Company shall be entitled to
participate in such action or proceeding with counsel of the Company's choice,
or compromise or settle such action or proceeding, at its expense (in which
case, the Company shall not thereafter be responsible for the fees and expenses
of any separate counsel retained by such Indemnified Person); provided, however,
that such counsel shall be satisfactory to the Indemnified Person in the
exercise of its reasonable judgment.

         Notwithstanding the Company's election to assume the defense of such
action or proceeding, such Indemnified Person shall have the right to employ
separate counsel and to participate in the defense of such action or proceeding,
and the Company shall bear the reasonable fees, costs and expenses of such
separate counsel (and shall pay such fees, costs and expenses, at least
quarterly), if (i) the use of counsel chosen by the Company to represent such
Indemnified Person would, in the written opinion of counsel to the Indemnified
Person, present such counsel with a conflict of interest, (ii) the defendants
in, or targets of, any such action or proceeding include both Indemnified
Person(s) and the Company, and such indemnified Person(s) shall have reasonably
concluded that there may be legal defenses available to it or to other
Indemnified Persons which are different from or additional to those available to
the Company (in which case, the Company shall not have the right to direct the
defense of such action or proceeding on behalf of the Indemnified Person), (iii)
the Company shall not have employed counsel within twenty (20) business days
after notice of the institution of such action or proceeding (or such shorter
period if necessitated by the action); or (iv) the Company shall authorize such
Indemnified Person to employ separate counsel at the Company expense; provided,
however, that all such Indemnified Persons shall be limited to, and the
Company's obligation hereunder to bear reasonable fees and expenses of separate
counsel shall be satisfied by, the employment of one counsel for such action for
all Indemnified Persons.

         In order to provide for just and equitable contribution, if a claim of
indemnification hereunder is found unenforceable in a final judgment by a court
of competent jurisdiction (not subject to further appeal), even though the
express provisions hereof provide for indemnification in such case, then the
Company and CTA shall contribute to the losses, claims, damages, judgments,
liability or costs to which the Indemnified Person may be subject in accordance
with the relative benefits received by, and the relative fault of, each in
connection with the statements, acts or omissions which resulted in such losses,
claims, damages, judgments, liabilities or costs, The parties agree that a pro

                                      -4-
<PAGE>

rata allocation would be unfair. No person found liable for a fraudulent
misrepresentation or omission shall be entitled to contribution from any person
who is not also found liable for such fraudulent misrepresentation or omission.
Notwithstanding the foregoing, CTA shall not be obligated to contribute to any
amount hereunder that exceeds the amount of fees previously received by CTA for
its services to the Company under this Agreement. These indemnification
provisions shall (i) remain operative and in full force and effect regardless of
(A) any termination of this Agreement other than for fraud, willful misconduct
or gross negligence, or (B) completion of the engagement by CTA; (ii) inure to
the benefit of any successors, assigns, heirs or personal representatives of any
Indemnified Person; and (iii) be in addition to any other rights that any
Indemnified Person may have.

         9. ENTIRE AGREEMENT. This Agreement represents the entire agreement
between the parties with respect to the subject matter hereof and may not be
modified, except in writing signed by both parties, This Agreement may be
executed in counterparts, each of which shall constitute an original. The
invalidity or unenforceability of any provision of this Agreement shall not

         10. SURVIVAL. The provisions of paragraphs 4 and 7 relating to the
Company's obligation in respect of CTA's fees and paragraph 8 relating to
indemnification shall survive any termination of this Agreement, in accordance
with their terms.

         11. BINDING OBLIGATION; CHOICE OF LAW; JURISDICTION. Upon execution by
both parties, and subject to the approval of the Company's Board of Directors,

and CTA. The parties agree that the laws of the State of New York shall apply
