connection with any reclassification, increase or reduction of capital, or
issued in connection with any reorganization, merger or consolidation), or any

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

7. Voting Rights; Dividends; Certificates.
 
(a) So long as no Event of Default has occurred and is continuing, Pledgor shall
be entitled (subject to the other provisions hereof, including, without
limitation, Section 10 below) to exercise its voting and other consensual rights
with respect to the Pledged Shares and otherwise exercise the incidents of
ownership thereof in any manner not inconsistent with this Agreement or the
Purchase Agreement and the other Transaction Documents. Pledgor hereby grants to
Pledgee or its nominee, an irrevocable proxy to exercise all voting and
corporate rights relating to the Pledged Shares in any instance, which proxy
shall be effective, at the discretion of Pledgee, upon the occurrence and during
the continuance of an Event of Default. Upon the request of Pledgee at any time,
Pledgor agrees to deliver to Pledgee such further evidence of such irrevocable
proxy or such further irrevocable proxies to vote the Pledged Shares as Pledgee
may request.
 
(b) Subject to any sale or other disposition by Pledgee of the Pledged Shares,
any other Pledged Collateral or other property pursuant to this Agreement, upon
the indefeasible full payment in cash, satisfaction and termination of all of
the Liabilities and the termination of this Agreement pursuant to Section 13
hereof and of the Liens and security interests hereby granted, the Pledged
Shares, the other Pledged Collateral and any other property then held as part of
the Pledged Collateral in accordance with the provisions of this Agreement shall
be promptly returned to Pledgor or to such other persons or entities as shall be
legally entitled thereto.
 
8. Rights of Pledgee. Pledgee shall maintain the custody, safekeeping and
physical preservation of the Pledged Shares in the same manner as Pledgee deals
with similar property for its own account. Pledgee shall not be liable for
failure to collect or realize upon the Liabilities or any collateral security or
guaranty therefor, or any part thereof, or for any delay in so doing, nor shall
Pledgee be under any obligation to take any action whatsoever with regard
thereto. Any or all of the Pledged Shares held by Pledgee hereunder may, if an
Event of Default has occurred and is continuing, without notice, be registered
in the name of Pledgee or its nominee, and Pledgee or its nominee may thereafter
without notice exercise all voting and corporate rights at any meeting with
respect to any Pledged Entity and exercise any and all rights of conversion,
exchange, subscription or any other rights, privileges or options pertaining to
any of the Pledged Shares as if it were the absolute owner thereof, including,
without limitation, the right to vote in favor of, and to exchange at its
discretion any and all of the Pledged Shares upon, the merger, consolidation,
reorganization, recapitalization or other readjustment with respect to any
Pledged Entity or upon the exercise by any Pledged Entity, Pledgor or Pledgee of
any right, privilege or option pertaining to any of the Pledged Shares, and in
connection therewith, to deposit and deliver any and all of the Pledged Shares
with any committee, depository, transfer agent, registrar or other designated
agency upon such terms and conditions as Pledgee may reasonably determine, all
without liability except to account for property actually received by Pledgee,
but Pledgee shall have no duty to exercise any of the aforesaid rights,
privileges or options and shall not be responsible for any failure to do so or
delay in so doing.
 

5

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

9. Remedies. Upon the occurrence and during the continuance of an Event of
Default, Pledgee may exercise in respect of the Pledged Collateral, in addition
to other rights and remedies provided for herein or otherwise available to it,
all the rights and remedies of a secured party under the Uniform Commercial Code
(“UCC”) in effect in the State of New York from time to time, whether or not the
UCC applies to the affected Pledged Collateral (or the Uniform Commercial Code
as in effect in any other relevant jurisdiction). Pledgee also, without demand
of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale) to or upon
Pledgor or any other person or entity (all and each of which demands,
advertisements and/or notices are hereby expressly waived), may forthwith
collect, receive, appropriate and realize upon the Pledged Collateral, or any
part thereof, and/or may forthwith date and otherwise fill in the blanks on any
assignments separate from certificates or stock power or otherwise sell, assign,
give an option or options to purchase, contract to sell or otherwise dispose of
and deliver said Pledged Collateral, or any part thereof, in one or more
portions at one or more public or private sales or dispositions, at any exchange
or broker’s board or at any of Pledgee’s offices or elsewhere upon such terms
and conditions as Pledgee may deem advisable and at such prices as it may deem
best, for any combination of cash and/or securities or other property or on
credit or for future delivery without assumption of any credit risk, with the
right to Pledgee upon any such sale, public or private, to purchase the whole or
any part of said Pledged Collateral so sold, free of any right or equity of
redemption in Pledgor, which right or equity is hereby expressly waived or
released. Pledgee shall apply the net proceeds of any such collection, recovery,
receipt, appropriation, realization, sale or disposition, after deducting all
costs and expenses of every kind incurred therein or incidental to the
safekeeping of any and all of the Pledged Collateral or in any way relating to
the rights of Pledgee hereunder, including attorneys’ fees and legal expenses,
to the payment, in whole or in part, of the Liabilities, in such order as
Pledgee may elect. Pledgor shall remain liable for any deficiency remaining
unpaid after such application. Only after so paying over such net proceeds and
after the payment by Pledgee of any other amount required by any provision of
law, including, without limitation, Section 9-608 of the UCC, need Pledgee
account for the surplus, if any, to Pledgor. Pledgor agrees that Pledgee will
give reasonable notice (such reasonable notice to be determined by Pledgee in
its sole and absolute discretion) of the time and place of any public sale or of
the time after which a private sale or other intended disposition is to take
place. No notification need be given to Pledgor if it has signed after default a
statement renouncing or modifying any right to notification of sale or other
intended disposition. The rights, remedies and powers conferred by this Section
9 are in addition to, and not in substitution for, any other rights, remedies or
powers that Pledgee may have under any Transaction Document, at law, in equity
or by or under the UCC or any other statute or agreement. Pledgee may proceed by
way of any action, suit or other proceeding at law or in equity and no right,
remedy or power of Pledgee will be exclusive of or dependent on any other.
Pledgee may exercise any of its rights, remedies or powers separately or in
combination and at any time.
 

6

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

10. No Disposition, Etc. Pledgor agrees that it will not sell, assign, transfer,
exchange, or otherwise dispose of, or grant any option with respect to, the
Pledged Shares or any other Pledged Collateral, nor will Pledgor create, incur
or permit to exist any Lien with respect to any of the Pledged Shares or any
other Pledged Collateral, or any interest therein, or any proceeds thereof,
except for the Lien and security interest of Pledgee provided for by this
Agreement and the Security Agreement.
 
11. Sale of Pledged Shares.
 
(a) Pledgor recognizes that Pledgee may be unable to effect a public sale or
disposition (including, without limitation, any disposition in connection with a
merger of a Pledged Entity) of any or all the Pledged Shares by reason of
certain prohibitions contained in the Securities Act of 1933, as amended (the
“1933 Act”), and applicable state securities laws, but may be compelled to
resort to one or more private sales or dispositions thereof to a restricted
group of purchasers who will be obliged to agree, among other things, to acquire
such securities for their own account, for investment and not with a view to the
distribution or resale thereof. Pledgor acknowledges and agrees that any such
private sale or disposition may result in prices and other terms (including the
terms of any securities or other property received in connection therewith) less
favorable to the seller than if such sale or disposition were a public sale or
disposition and, notwithstanding such circumstances, agrees that any such
private sale or disposition shall be deemed to be reasonable and affected in a
commercially reasonable manner. Pledgee shall be under no obligation to delay a
sale or disposition of any of the Pledged Shares in order to permit Pledgor or a
Pledged Entity to register such securities for public sale under the 1933 Act,
or under applicable state securities laws, even if Pledgor or a Pledged Entity
would agree to do so.
 
(b) Pledgor further agrees to do or cause to be done all such other acts and
things as may be reasonably necessary to make such sales or dispositions of the
Pledged Shares valid and binding and in compliance with any and all applicable
laws, regulations, orders, writs, injunctions, decrees or awards of any and all
courts, arbitrators or governmental instrumentalities, domestic or foreign,
having jurisdiction over any such sales or dispositions, all at Pledgor's
expense. Pledgor further agrees that a breach of any of the covenants contained
in Sections 6, 7(a), 10, 11 and 26 will cause irreparable injury to Pledgee and
that Pledgee has no adequate remedy at law in respect of such breach and, as a
consequence, agrees, without limiting the right of Pledgee to seek and obtain
specific performance of other obligations of Pledgor contained in this
Agreement, that each and every covenant referenced above shall be specifically
enforceable against Pledgor, and Pledgor hereby waives and agrees not to assert
any defenses against an action for specific performance of such covenants.
 

7

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

(c) Pledgor further agrees to indemnify and hold harmless the Buyers, Pledgee
and their respective successors and assigns, their respective officers,
directors, employees, attorneys and agents, and any person or entity in control
of any thereof, from and against any loss, liability, claim, damage and expense,
including, without limitation, legal fees and expenses (in this paragraph
collectively called the “Indemnified Liabilities”), under federal and state
securities laws or otherwise insofar as such Indemnified Liability (i) arises
out of or is based upon any untrue statement or alleged untrue statement of a
material fact contained in any registration statement, prospectus or offering
memorandum or in any preliminary prospectus or preliminary offering memorandum
or in any amendment or supplement to any thereof or in any other writing
prepared in connection with the offer, sale or resale of all or any portion of
the Pledged Collateral unless such untrue statement of material fact was
provided by Pledgee, in writing, specifically for inclusion therein, or (ii)
arises out of or is based upon any omission or alleged omission to state therein
a material fact required to be stated or necessary to make the statements
therein not misleading, such indemnification to remain operative regardless of
any investigation made by or on behalf of Pledgee or any successor thereof, or
any person or entity in control of any thereof. In connection with a public sale
or other distribution, Pledgor will provide customary indemnification to any
underwriters, their successors and assigns, officers and directors and each
person or entity who controls any such underwriter (within the meaning of the
1933 Act). If and to the extent that the foregoing undertakings in this
paragraph may be unenforceable for any reason, Pledgor agrees to make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. The obligations of
Pledgor under this paragraph (c) shall survive any termination of this
Agreement.
 
(d) Pledgor further agrees to waive any and all rights of subrogation it may
have against a Pledged Entity upon the sale or disposition of all or any portion
of the Pledged Collateral by Pledgee pursuant to the terms of this Agreement
until the termination of this Agreement in accordance with Section 13 below.
 
12. No Waiver; Cumulative Remedies. Pledgee shall not by any act, delay,
omission or otherwise be deemed to have waived any of its remedies hereunder,
and no waiver by Pledgee shall be valid unless in writing and signed by Pledgee,
and then only to the extent therein set forth. A waiver by Pledgee of any right
or remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which Pledgee would otherwise have on any further occasion. No
course of dealing between Pledgor and Pledgee and no failure to exercise, nor
any delay in exercising on the part of Pledgee or the Buyers of, any right,
power or privilege hereunder or under the other Transaction Documents shall
impair such right or remedy or operate as a waiver thereof; nor shall any single
or partial exercise of any right, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein provided are cumulative and may be
exercised singly or concurrently, and are not exclusive of any rights or
remedies provided by law or in the Purchase Agreement.
 
13. Termination. (a) This Agreement and the Liens and security interests granted
hereunder shall terminate, (b) Pledgee shall promptly return any Pledged
Collateral then held by Pledgee in accordance with the provisions of this
Agreement to Pledgor, and (c) Pledgee shall, at the expense of Pledgor, promptly
after Pledgee’s receipt of Pledgor’s written request, execute and deliver to
Pledgor such documents as Pledgor shall reasonably request in writing, to
evidence such termination described in clause (a) herein and the return of such
Pledged Collateral to Pledgor, upon the termination of the Notes and the full
and complete performance and indefeasible satisfaction of all of the Liabilities
(including, without limitation, the indefeasible payment in full in cash of all
such Liabilities) and with respect to which claims have been asserted by Pledgee
and/or Buyers.
 

8

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

14. Possession of Pledged Collateral. Beyond the exercise of reasonable care to
assure the safe custody of the Pledged Shares in the physical possession of
Pledgee pursuant hereto, neither Pledgee, nor any nominee of Pledgee, shall have
any duty or liability to collect any sums due in respect thereof or to protect,
preserve or exercise any rights pertaining thereto (including any duty to
ascertain or take action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relating to the Pledged Collateral and any
duty to take any necessary steps to preserve rights against any parties with
respect to the Pledged Collateral), and shall be relieved of all responsibility
for the Pledged Collateral upon surrendering them to Pledgor. Pledgor assumes
the responsibility for being and keeping itself informed of the financial
condition of a Pledged Entity and of all other circumstances bearing upon the
risk of non-payment of the Liabilities, and Pledgee shall have no duty to advise
Pledgor of information known to Pledgee regarding such condition or any such
circumstance. Pledgee shall have no duty to inquire into the powers of a Pledged
Entity or its officers, directors, managers, members, partners or agents thereof
acting or purporting to act on its behalf.
 
15. Taxes and Expenses. Pledgor will upon demand pay to Pledgee, (a) any taxes
(excluding income taxes, franchise taxes or other taxes levied on gross
earnings, profits or the like of Pledgee) payable or ruled payable by any
Governmental Authority in respect of this Agreement, together with interest and
penalties, if any, and (b) all expenses, including the fees and expenses of
counsel for Pledgee and of any experts and agents that Pledgee may incur in
connection with (i) the administration, modification or amendment of this
Agreement, (ii) the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Pledged Collateral, (iii) the exercise or
enforcement of any of the rights of Pledgee hereunder, or (iv) the failure of
Pledgor to perform or observe any of the provisions hereof.
 
16. Pledgee Appointed Attorney-In-Fact. Pledgor hereby irrevocably appoints
Pledgee as Pledgor’s attorney-in-fact, with full authority in the place and
stead of Pledgor and in the name of Pledgor or otherwise, from time to time in
Pledgee’s discretion, to take any action and to execute any instrument that
Pledgee deems reasonably necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation, (i) to receive, endorse and
collect all instruments made payable to Pledgor representing any dividend,
interest payment or other distribution in respect of the Pledged Collateral or
any part thereof and to give full discharge for the same, when and to the extent
permitted by this Agreement and (ii) to complete any assignment separate from
certificate delivered hereunder; provided that the power of attorney granted
hereunder shall only be exercised by Pledgee after the occurrence and during the
continuance of an Event of Default. The power of attorney granted hereunder is a
power coupled with an interest and shall be irrevocable until the Liabilities
are indefeasibly paid in full in cash and this Agreement is terminated in
accordance with Section 13 hereof
 

9

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

17. Governing Law; Jurisdiction; Jury Trial. All questions concerning the
construction, validity, enforcement and interpretation of this Agreement shall
be governed by the internal laws of the State of New York, without giving effect
to any choice of law or conflict of law provision or rule (whether of the State
of New York or any other jurisdiction) that would cause the application of the
laws of any jurisdiction other than the State of New York. Each party hereby
irrevocably submits to the non-exclusive jurisdiction of the state and federal
courts sitting in the City of New York, borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is brought in an inconvenient forum or that the
venue of such suit, action or proceeding is improper. Each party hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof to such

Agreement.
