Secured Promissory Notes due, unless demanded earlier pursuant to the terms
therein, December 31, 2007 (collectively, the “Pledgees”).

Secured Promissory Notes of the Company (the “Notes”);

WHEREAS, pursuant to the provisions of the Notes, and as a condition to the
obligation of the Pledgees to lend thereunder, the Pledgors, as principals,
employees and shareholders of the Company, have agreed to make the pledge
contemplated by this Agreement in order to induce Pledgees to perform their
obligations under the Notes;

 WHEREAS, as a condition to the obligation of the Pledgees to lend pursuant to
the Notes, the Company agrees to undertake such action contemplated by this
Agreement in order to induce Pledgees to perform their obligations under the
Notes;

WHEREAS, Pledgors own the shares of common stock, $0.001 par value per share, of
the Company (the “Common Stock”), set forth opposite the Pledgors’ names on
Schedule A attached hereto;

WHEREAS, terms used but not otherwise defined in this Agreement that are defined
in Article 9 of the Uniform Commercial Code in effect in the State of New York
at that time (whether or not the UCC applies to the affected Pledged Collateral)
(the "UCC") shall have the meanings ascribed to them in the UCC; and

NOW, THEREFORE, in consideration of the premises, covenants and promises
contained herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as

irrevocably pledges, grants and hypothecates to the Pledgees, and grants to the
Pledgees a continuing first priority security interest in, a first lien upon and
a right of set-off against, all of its respective rights, titles and interests
of whatsoever kind and nature in (the “Security Interest”), and to secure the
complete and timely payment, performance and discharge in full, as the case may
be, of all of the obligations pursuant to the Notes, the following
(collectively, the “Pledged Collateral”):
 

--------------------------------------------------------------------------------

(a) the shares of Common Stock owned by such Pledgor and set forth on Schedule A
attached hereto (the “Pledged Shares”), and all dividends, cash, instruments and

hereof, all certificates representing or evidencing the Pledged Shares, in
suitable form for transfer by delivery, or accompanied by instruments of

delivered to the Agent, as collateral agent for the Pledgees. The Agent shall
have the right, at any time after the occurrence of an Event of Default (as
hereinafter defined)(unless waived in writing by the Pledgees), without notice
to the Pledgor, to transfer to or to register in the name of the Pledgees or
their nominees any or all of the Pledged Collateral. In addition, the Agent
shall have the right at any time after the occurrence of an Event of Default
(unless waived in writing by the Pledgees), to exchange certificates or
instruments representing or evidencing Pledged Collateral for certificates or
instruments of smaller or larger denominations.
 
SECTION 4. Representations and Warranties. Each Pledgor, severally and not
jointly with the other Pledgors, represents and warrants as follows:

record and beneficial owner of the Pledged Collateral owned by such Pledgor,
free and clear of any lien, security interest, restriction, option or other
charge or encumbrance (collectively, "Liens").
 
(b) The pledge of the Pledged Collateral and the grant of the Security Interest
pursuant to this Agreement creates a valid and perfected first priority security
interest in the Pledged Collateral, securing payment and performance of the
Obligations.

proper filing and recording agencies in the jurisdictions indicated on Schedule
B, attached hereto, no consent of any other person or entity and no
authorization, approval, or other action by, and no notice to or filing with,
any governmental authority or regulatory body is required (i) for the pledge by

execution, delivery or performance of this Agreement by the Pledgor, (ii) for
the perfection or maintenance of the security interest created hereby, or (iii)
for the exercise by the Agent of the voting or other rights provided for in this
Agreement or the remedies in respect of the Pledged Collateral pursuant to this
Agreement (except as may be required in connection with any disposition of any

assignments, security agreements, financing statements or other instruments,

Collateral.
 
(h) All information heretofore, herein or hereafter supplied to the Pledgees by

other Pledgors, agrees that at any time and from time to time, at the expense of
such Pledgor, the Pledgor shall promptly execute and deliver all further
instruments and documents, and take all further action, that may be necessary or
desirable, or that the Agent and/or the Pledgees may reasonably request, in
order to perfect and protect any security interest granted or purported to be
granted hereby or to enable the Agent and/or Pledgees to exercise and enforce
their rights and remedies hereunder with respect to any Pledged Collateral. The
Company agrees that at any time and from time to time, at the expense of the
Company, the Company shall promptly execute and deliver all further instruments
and documents, and take all further action, that may be necessary or desirable,
or that the Pledgees may reasonably request.

Default is waived in writing by the Pledgees):
 
(i) Each Pledgor shall be entitled to exercise or refrain from exercising any
and all voting and other consensual rights pertaining to the Pledged Collateral
or any part thereof for any purpose not inconsistent with the terms of this
Agreement; provided, however, that such Pledgor shall not exercise or refrain
from exercising any such right if, in the reasonable judgment of such Pledgees,
such action would have a material adverse effect on the Security Interest or the
rights and remedies of the Pledgees hereunder; provided, further, that such
Pledgor shall give the Pledgees at least ten (10) days' prior written notice of
the manner in which it intends to exercise, or the reasons for refraining from
exercising, any such right.

and other consensual rights which it would otherwise be entitled to exercise
pursuant to Section 6(a)(i) and to receive the dividends and interest payments
which it would otherwise be authorized to receive and retain pursuant to Section

Agent who shall thereupon have the sole right to exercise or refrain from
exercising such voting and other consensual rights and to receive and hold as
Pledged Collateral such dividends and interest payments.
 
(ii) All dividends and interest payments which are received by the Pledgors
contrary to the provisions of paragraph (i) of this Section 6(b) shall be

endorsement).

Agreement, the Pledgor agrees that it shall not (i) sell, assign (by operation
of law or otherwise) or otherwise dispose of, or grant any option with respect
to, any of the Pledged Collateral, or (ii) create or permit to exist any Lien
upon or with respect to any of the Pledged Collateral, except for the security
interest granted pursuant to this Agreement.

Pledgors, to, after the occurrence and during the continuance of an Event of

against any parties or any other rights pertaining to any Pledged Collateral.
The Agent and Pledgee shall be deemed to have exercised reasonable care in the
custody and preservation of any Pledged Collateral in its possession if such
Pledged Collateral is accorded treatment substantially equal to that which such
party accords its own property.

--------------------------------------------------------------------------------

SECTION 11. Event of Default. The occurrence of any of the following events
shall constitute an event of default under this Agreement (each, an “Event of
Default”):
 
(a) The failure of any Pledgor to observe, perform or comply with any act, duty,
covenant, agreement or obligation under this Agreement, which is not cured
within ten business days following written notice by Agent to such Pledgor;
 
(b) If any of the representation or warranty of any Pledgor set forth in this
Agreement shall be breached or shall be untrue or incorrect in any material
respect, and is not cured within ten business days following written notice by
Agent to such Pledgor;
 
(c) The filing of any financing statement with regard to any of the Pledged
Collateral other than pursuant to this Agreement, or the attachment of any
additional Lien to any portion of the Pledged Collateral in favor of any Person
other than the Pledgees; or
 
(d) If any event of default (and expiration of any cure period) shall occur
(unless such event of default is waived in writing by the Pledgees) under any of
the other Transaction Documents.
 
SECTION 12. Cross-Default; Cross-Collateralization.
 
The Pledgors acknowledges and agrees that any default under the terms of this
Agreement shall constitute a default by the Company under the Notes, and that
any event of default (following expiration of any applicable cure period) under
the Notes shall constitute a default under this Agreement.

SECTION 13. Remedies upon Event of Default. Upon and after the occurrence of any
Event of Default:
 
(a) The Agent may exercise in respect of the Pledged Collateral, in addition to
other rights and remedies provided for herein or otherwise available to the
Agent (including, without limitation, the vesting in the Agent pursuant to
Section 6(b)(i) of the sole right to exercise voting rights pertaining to the
Pledged Collateral, including, without limitation, voting rights with respect to
the sale of assets of the issuer of such Pledged Collateral), all the rights and
remedies of a secured party on default under the UCC, and may also, without
notice except as specified below and subject to the applicable securities laws,
sell the Pledged Collateral or any part thereof at public or private sale, at
any exchange, broker's board or at any of the Agent's offices or elsewhere, for
cash, on credit or for future delivery, and upon such other terms as the Agent
may deem commercially reasonable. Each Pledgor agrees that, to the extent notice
of sale shall be required by law, at least ten (10) days’ notice to such Pledgor
of the time and place of any public sale or the time after which any private
sale is to be made shall constitute reasonable notification. The Agent shall not
be obligated to make any sale of Pledged Collateral regardless of notice of sale
having been given. The Agent may adjourn any public or private sale from time to
time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned. Each Pledgor acknowledges and agrees that the Pledged Collateral
consisting of the Pledged Shares, and/or any other shares of common stock of the
Company, is of a type customarily sold on a recognized market, and accordingly
that no notice of the sale thereof need be given. In addition, Agent may
transfer all of the Pledged Collateral to Pledgees, who may hold all of such
Pledged Collateral as payment in full of the Obligations
 

6

(b) Any cash held by the Agent or the Pledgees as Pledged Collateral and all
cash proceeds received by the Agent or the Pledgees in respect of any sale of,
collection from, or other realization upon all or any part of the Pledged
Collateral may, in the discretion of the Agent or the Pledgees, be held as
collateral for, and/or then or at any time thereafter be applied (after payment
of any amounts payable pursuant to Section 14) in whole or in part against, all
or any part of the Obligations. Any surplus of such cash or cash proceeds held
by the Agent or the Pledgees and remaining after payment in full of all the
Obligations shall be paid over to the Pledgors, pro-rata, or to whomsoever may
be lawfully entitled to receive such surplus.
 
SECTION 14. Expenses. The Pledgors and the Company, severally and jointly, shall
upon demand pay to the Agent and/or the Pledgees the amount of any and all
reasonable expenses, including reasonable attorneys’ fees and expenses and the
reasonable fees and expenses of any experts and agents, which the Agent and/or
Pledgees may incur in connection with (a) the administration of this Agreement,
(b) the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Pledged Collateral, (c) the exercise or enforcement
of any of the rights of the Agent and/or Pledgees hereunder or (d) the failure
by any Pledgor to perform or observe any of the provisions hereof.
 
SECTION 15. Continuing Security Interest; Termination. This Agreement shall
create a continuing security interest in the Pledged Collateral and shall remain
in full force and effect until the indefeasible payment in full of the
Obligations. Upon the indefeasible payment in full of the Obligations, the
security interest granted hereby shall terminate and all rights to the Pledged
Collateral shall revert to the Pledgors. Upon any such termination, the Agent
shall, at such Pledgors’ expense, return, pro-rata, to the Pledgors such of the
Pledged Collateral as shall not have been sold or otherwise applied pursuant to
the terms hereof and execute and deliver to such Pledgors such documents as such
Pledgors shall reasonably request to evidence such termination.
 
SECTION 16. Governing Law; Terms. For the convenience of the Agent, this
Agreement shall be governed by, and construed in accordance with, the laws of
the State of New York, without regard to principles of conflict of laws. Each
Pledgor agrees to submit to the in personam jurisdiction of the state and
federal courts situated within the City of New York, State of New York with
regard to any controversy arising out of or relating to this Agreement. Unless
otherwise defined herein, terms defined in Article 9 of the UCC are used herein
as therein defined.

SECTION 17. Notice. All notices and other communications hereunder shall be in
writing and shall be deemed to have been received when delivered personally

certified mail, return receipt requested, postage prepaid, to the addresses of
the parties as set forth herein.
 
SECTION 18. Waivers.
 
(a) Waivers. Each Pledgor waives any right to require the Pledgees to (i)
proceed against any person, (ii) proceed against any other collateral under any
other agreement, (iii) pursue any other remedy, or (iv) make presentment,
demand, dishonor, notice of dishonor, acceleration and/or notice of non-payment.
 
(b) Waiver of Defense. No course of dealing between the Pledgors and the
Pledgees, nor any failure to exercise nor any delay in exercising on the part of
the Agent or Pledgees, any right, power, or privilege under this Agreement or
under any of the other Transaction Documents shall operate as a waiver. No
single or partial exercise of any right, power, or privilege under this
Agreement or under any of the other Transaction Documents shall preclude any
other or further exercise of such right, power, or privilege or the exercise of
any other right, power, or privilege.
 
SECTION 19. Rights Are Cumulative. All rights and remedies of the Agent and the
Pledgees with respect to the Pledged Collateral, whether established by this
Agreement, the other Transaction Documents or by law, shall be cumulative and
may be exercised concurrently or in any order.
 
SECTION 20. Indemnity. Each Pledgor, jointly and severally, agrees to indemnify
and hold harmless the Agent, the Pledgees and their respective heirs, successors
and assigns against and from all liabilities, losses and costs (including,
without limitation, reasonable attorneys' fees) arising out of or relating to
the taking or the failure to take action in respect of any transaction effected
under this Agreement or in connection with the lien provided for herein,
including, without limitation, any and all excise, sales or other taxes which
may be payable or determined to be payable with respect to any of the Pledged
Collateral, except to the extent resulting from their gross negligence or
intentional misconduct. The liabilities of the Pledgors under this Section 20
shall survive the termination of this Agreement.
 
SECTION 21. Severability. The provisions of this Agreement are severable. If any
provision of this Agreement is held invalid or unenforceable in whole or in part
in any jurisdiction, then such invalidity or unenforceability shall affect only
such provision, or part thereof, in such jurisdiction, and shall not in any
manner affect such provision or part thereof in any other jurisdiction, or any
other provision of this Agreement in any jurisdiction. 
 
SECTION 22. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be considered an original, but all of which
together shall constitute one and the same instrument.
 
SECTION 23. Amendments; Entire Agreement. This Agreement is subject to
modification only by a writing signed by the parties. To the extent any
provision of this Agreement conflicts with any provision of the Notes, the
provision giving Pledgees greater rights or remedies shall govern, it being
understood that the purpose of this Agreement is to add to, and not detract
from, the rights granted to Pledgees under the Notes. This Agreement and the
other Transaction Documents constitute the entire agreement of the parties with
respect to the subject matter of this Agreement.

SECTION 24. Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective heirs,
executors, legal representatives, successors and assigns; provided, however,

or delegate any rights, powers, duties or obligations hereunder, and any such
purported assignment or delegation without such consent shall be null and void.
