     (i)  all Proceeds of any of the foregoing.

Notwithstanding the foregoing, the Collateral shall  not  include
any license or permit issued by a governmental authority, in each
case  to  the  extent  and  only to the extent  that  granting  a
security interest in such license or permit is prohibited by law;
provided,  however,  that (i) the Collateral  shall  include  the
proceeds   of,   and  the  right  to  receive  money   or   other
consideration  in connection with, any direct or  indirect  sale,
assignment or transfer of any such license or permit and (ii)  to
the  extent that such a security interest is now or at  any  time
hereafter  not  prohibited by law, then  each  Pledgor  shall  be
deemed to have granted such security interest and the same  shall
attach  without any further action and be fully effective  as  of
the  time permitted (giving effect to any retroactive application
of  any  change in the law).  If requested by the Pledgee at  any
time  and  from time to time, each Pledgor will (and  will  cause
each  of  its  Subsidiaries  to) execute  and  deliver  all  such
instruments and documents, and take such other actions  as  shall
be  necessary or desirable (in the sole judgment of the  Pledgee)
in  order  to  create  and  perfect a security  interest  in  the
Collateral (including, without limitation, any license or permit,
to the extent, if any, permitted by law).

      Section  3.  Representations and Warranties.  Each  Pledgor
hereby represents and warrants to the Pledgee as follows:

      (a)   Title  and Liens.  Such Pledgor is, and will  at  all
times  continue  to  be, the legal and beneficial  owner  of  the
Collateral of such Pledgor. None of the Collateral is subject  to
any  adverse claim or other Lien other than Permitted Liens.   No
Person  has  control  of  any of the Collateral  other  than  the
Pledgee.

      (b)   Authorization.  Such Pledgor has the right and power,
and  has  taken all necessary action to authorize it, to execute,
deliver and perform this Agreement in accordance with its  terms.
The  execution,  delivery and performance of  this  Agreement  in
accordance with its terms, including the granting of the security
interest hereunder, do not and will not, by the passage of  time,
the  giving  of  notice,  or both: (i) require  any  Governmental
Approval  or violate any Applicable Law relating to such Pledgor;
(ii) conflict with, result in a breach of or constitute a default
under  the  organizational documents  of  such  Pledgor,  or  any
indenture, agreement or other instrument to which such Pledgor is
a  party  or by which it or any of the Collateral of such Pledgor
or its other property may be bound; or (iii) result in or require
the  creation or imposition of any Lien upon or with  respect  to
any  of  the  Collateral of such Pledgor or such Pledgor's  other
property whether now owned or hereafter acquired.

      (c)   Validity  and Perfection of Security Interest.   This
Agreement is effective to create in favor of the Pledgee, for the
benefit  of the Pledgee, a legal, valid and enforceable  security
interest  in  the  Collateral.  Such security  interest  will  be
perfected  (i)  with  respect to any such Collateral  that  is  a
"security" (as such term is defined in the UCC) and is evidenced


                                5

<Page>

by  a  certificate,  when such Collateral  is  delivered  to  the
Pledgee  with  duly executed stock powers with  respect  thereto,
(ii) with respect to any such Collateral that is a "security" (as
such  term  is  defined in the UCC) but is  not  evidenced  by  a
certificate,  when UCC financing statements in  appropriate  form
are  filed  in the appropriate filing offices in the jurisdiction
of organization of the Pledgors or when control is established by
the  Pledgee over such interests in accordance with the provision
of  Section  8-106  of the UCC, or any successor  provision,  and
(iii)  with  respect  to  any  such  Collateral  that  is  not  a
"security"  (as  such  term is defined  in  the  UCC),  when  UCC
financing  statements  in  appropriate  form  are  filed  in  the
appropriate filing offices in the jurisdiction of organization of
the  Pledgors.  Except as set forth in this subsection, no action
is  necessary  to perfect the security interest  granted  by  any
Pledgor under this Agreement.

     (d)  Pledged Equity Interests.  The information set forth on
Schedule 1 hereto with respect to the Collateral of such  Pledgor
is true and correct.

      (e)   Name, Organization, Etc.  Such Pledgor's exact  legal
name,   type   of   legal  entity,  jurisdiction  of   formation,
organizational identification number and location  of  its  chief
executive office are as set forth on Schedule 1.  Except  as  set
forth  on  such  Schedule,  since  the  date  of  such  Pledgor's
formation,  such Pledgor has not changed its name or merged  with
or otherwise combined its business with any other Person.

     (f)  Authorization of Equity Interest.  All Equity Interests
which  constitute Collateral are duly authorized, validly issued,
fully  paid  and nonassessable and are not subject to  preemptive
rights of any Person.

      (g)   Interests  in  Partnerships and LLCs.   None  of  the
Collateral  consisting of an interest in a partnership  or  in  a
limited  liability  company  (i) is  dealt  in  or  traded  on  a
securities exchange or in securities markets, (ii) by  its  terms
expressly provides that it is a security governed by Article 8 of
the UCC or (iii) is an investment company security.

      Section 4.  Covenants.  Each Pledgor hereby unconditionally
covenants and agrees as follows:

     (a)  No Liens; No Sale of Collateral.  Such Pledgor will not
create,  assume, incur or permit or suffer to exist  any  adverse
claim or other Lien on any of the Collateral other than Permitted
Liens  and  shall  not  enter into any  document,  instrument  or
agreement (other than this Agreement) which prohibits or purports
to  prohibit the creation or assumption of any Lien on any of the
Collateral.   Such  Pledgor will not sell, lease,  lend,  assign,
transfer  or  otherwise  dispose of all or  any  portion  of  the
Collateral  (or  any  interest therein) except  in  the  ordinary
course of business.

      (b)   Change of Name, Etc.  Without giving the  Pledgee  at
least 30-days' prior written notice and to the extent such action
is  not  otherwise prohibited by any of the Loan Documents,  such
Pledgor  shall  not:   (i) change its name;  (ii)  reorganize  or
otherwise become formed under the laws of another jurisdiction or
(iii)  become  bound by a security agreement  of  another  Person
under Section 9-203(d) of the UCC.

its title to and ownership of the Collateral of such Pledgor,  at
its sole cost and expense, against the claims of all Persons.

receive  any  certificate  (including,  without  limitation,  any
certificate  representing a stock and/or  liquidating  dividends,
other  distributions  in property, return  of  capital  or  other
distributions  made  on or in respect of the Collateral,  whether
resulting from a subdivision, combination or reclassification  of
outstanding   Equity  Interests  or  received  in  exchange   for
Collateral  or  any part thereof or as a result  of  any  merger,
consolidation, acquisition or other exchange of assets or on  the
liquidation,  whether  voluntary or involuntary,  or  otherwise),
instrument,  option  or  rights in  respect  of  any  Collateral,
whether  in addition to, in substitution of, as a conversion  of,
or  in  exchange  for,  any Collateral, or otherwise  in  respect
thereof,  such  Pledgor  shall hold the same  in  trust  for  the
Pledgee and promptly deliver the same to the Pledgee in the exact
form  received, duly indorsed by such Pledgor to the Pledgee,  if
required,  together  with an undated stock  power  covering  such
certificate  (or other appropriate instrument of  transfer)  duly
executed  in  blank by such Pledgor and with, if the  Pledgee  so
requests,  signature  guaranteed, to  be  held  by  the  Pledgee,
subject to the terms of this Agreement, as Collateral.

       (e)   Uncertificated  Securities.   With  respect  to  any
Collateral that constitutes a security and is not represented  or
evidence by a certificate or instrument, such Pledgor shall cause
the  Issuer  thereof either (i) to register the  Pledgee  as  the
registered  owner  of such security or (ii) to agree  in  writing
with  the  Pledgee and such Pledgor that such Issuer will  comply
with the instructions with respect to such security originated by
the Pledgee without further consent of such Pledgor.

      (f)   Security Entitlements and Securities Accounts.   With
respect to any Collateral consisting of a security entitlement or
a  securities  account, such Pledgor shall, and shall  cause  the
applicable  securities intermediary, to enter into  an  agreement
with,  and  in  form and substance acceptable  to,  the  Pledgee,
granting control to the Pledgee over such Collateral.

      (g)  Additional Shares.  Such Pledgor shall not permit  any
Issuer  to  issue  any  additional Equity Interests  unless  such
Equity  Interests  are  pledged  hereunder  as  provided  herein.
Further,  such Pledgor shall not permit any Issuer  to  amend  or
modify its articles or certificate of incorporation, articles  of
organization,   certificate  of  limited  partnership,   by-laws,
operating  agreement, partnership agreement or  other  comparable
organizational  instrument  in  a manner  which  would  adversely
affect  the  voting,  liquidation, preference  or  other  similar
rights of any holder of the Equity Interests pledged hereunder.

      (h)   Issuer Acknowledgment.  Such Pledgor shall, upon  the
Pledgee's  request  therefor, cause  each  Issuer  of  Collateral
pledged by such Pledgor and which Issuer is not a Pledgor itself,
to  execute  and  deliver to the Pledgee  an  Acknowledgment  and
Consent substantially in the form of Schedule 2 attached hereto.

     an  owner  of  the  Collateral or any part thereof  for  any
     purpose  not  inconsistent with the terms and conditions  of

Pledgee,  without  commingling  the  same  with  other  funds  or

Pledgee  in its discretion shall deem appropriate.  With  respect
to   any   Collateral  held  or  maintained  with  a   securities
intermediary,  the  Pledgee  shall be  entitled  to  notify  such
securities intermediary that such securities intermediary  should
follow  the  entitlement  orders of the  Pledgee  and  that  such
securities  intermediary  should  no  longer  follow  entitlement
orders  of  the Pledgor, without further consent of the  Pledgor.
The  Pledgee  shall  have the right (in  its  sole  and  absolute
discretion)  to register any Equity Interests which are  part  of
the  Collateral  in its own name as pledgee or the  name  of  its
nominee  (as  Pledgee or as sub-agent), endorsed or  assigned  in
blank  or  in  favor  of  the  Pledgee.   The  Pledgee  shall  be
authorized  at any sale (if it deems it advisable to  do  so)  to
restrict  the  prospective bidders or purchasers to  Persons  who
will  represent and agree that they are purchasing the Collateral
for  their own account in compliance with the Securities Act  and
any  other Applicable Law and upon consummation of any such  sale
the Pledgee shall have the right to assign, transfer, endorse and
deliver to the purchaser or purchasers thereof the Collateral  so
sold.   Each purchaser at any sale of Collateral shall  take  and
hold the property sold absolutely free from any claim or right on
the  part of any Pledgor, and each Pledgor hereby waives (to  the
fullest  extent  permitted  by  Applicable  Law)  all  rights  of
redemption, stay and/or appraisal which such Pledgor now  has  or
may  at any time in the future have under any Applicable Law  now
existing or hereafter enacted.  Each Pledgor agrees that, to  the
extent  notice  of sale shall be required by Applicable  Law,  at
least  5  days' prior written 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.  Any
such  public  sale  shall be held at such time  or  times  within
ordinary  business  hours and at such  place  or  places  as  the
Pledgee may fix and shall state in the notice or publication  (if
any)  of such sale.  At any such sale, the Collateral, or portion
thereof to be sold, may be sold in one lot as an entirety  or  in
separate  parcels, as the Pledgee may determine in its  sole  and
absolute discretion.  The Pledgee shall not be obligated to  make
any  sale  of the Collateral if it shall determine not to  do  so
regardless of the fact that notice of sale of the Collateral  may
have been given.  The Pledgee may, without notice or publication,
adjourn  any  public  or private sale or cause  the  same  to  be
adjourned from time to time by announcement at the time and place
fixed  for  sale, and such sale may, without further  notice,  be
made  at  the time and place to which the same was so  adjourned.
In  case the sale of all or any part of the Collateral is made on
credit  or  for future delivery, the Collateral so  sold  may  be
retained  by  the Pledgee until the sale price  is  paid  by  the
purchaser or purchasers thereof, but the Pledgee shall not  incur
any  liability  to  any  Pledgor in case any  such  purchaser  or
purchasers shall fail to take up and pay for the Collateral so


                                9

<Page>

sold  and,  in case of any such failure, such Collateral  may  be
sold again upon like notice.  At any public sale made pursuant to
this  Agreement, the Pledgee and any other holder of any  of  the
Secured  Obligations, to the extent permitted by Applicable  Law,
may  bid for or purchase, free from any right of redemption, stay
and/or  appraisal  on the part of any Pledgor  (all  said  rights
being also hereby waived and released to the extent permitted  by
Applicable  Law), any part of or all the Collateral  offered  for
sale.   For purposes hereof, a written agreement to purchase  all
or any part of the Collateral shall be treated as a sale thereof;
the Pledgee shall be free to carry out such sale pursuant to such
agreement and no Pledgor shall be entitled to the return  of  any
Collateral  subject thereto, notwithstanding the fact that  after
the  Pledgee shall have entered into such an agreement all Events
of  Default may have been remedied or the Secured Obligations may
have  been paid in full as herein provided.  Each Pledgor  hereby
waives  any  right to require any marshaling of  assets  and  any
similar  right.   In  addition to exercising the  power  of  sale
herein  conferred upon it, the Pledgee shall also have the option
to proceed by suit or suits at law or in equity to foreclose this
Agreement and sell the Collateral or any portion thereof pursuant
to  judgment  or  decree  of a court or courts  having  competent
jurisdiction.  The rights and remedies of the Pledgee under  this
Agreement  are  cumulative and not exclusive  of  any  rights  or
remedies which it otherwise has.

      Section 7.  Application of Proceeds of Sale and Cash.   The
proceeds  of any sale of the whole or any part of the Collateral,
together  with  any  other moneys held by the Pledgee  under  the
provisions  of  this  Agreement, shall be applied  first  to  pay
incurred  and unpaid fees and expenses of the Pledgee  under  the
Loan  Documents,  second, to the Pledgee for  application  by  it
towards  payment  of  the  Secured Obligations,  and  third,  any
balance  of  such  proceeds remaining after the then  outstanding
Secured Obligations have been paid in full in cash, shall be paid
to  the  Borrower  or to whomsoever may be lawfully  entitled  to
receive the same.  Each Pledgor shall remain liable and will pay,
on  demand,  any deficiency remaining in respect of  the  Secured
Obligations.

       Section  8.   Pledgee  Appointed  Attorney-in-Fact.   Each
Pledgor  hereby  constitutes  and appoints  the  Pledgee  as  the
attorney-in-fact of such Pledgor with full power of  substitution
either in the Pledgee's name or in the name of such Pledgor to do
any  of  the  following: (a) to perform any  obligation  of  such
Pledgor hereunder in such Pledgor's name or otherwise; (b) to ask
for,   demand,  sue  for,  collect,  receive,  receipt  and  give
acquittance for any and all moneys due or to become due under and
by  virtue  of  any  Collateral; (c) to prepare,  execute,  file,
record  or  deliver  notices, assignments, financing  statements,
continuation  statements, applications for registration  or  like
papers  to  perfect,  preserve or release the Pledgee's  security
interest  in  the  Collateral; (d) to issue  entitlement  orders,
instructions  and other orders to any securities intermediary  in
connection with any of the Collateral held by or maintained  with
such securities intermediary; (e) to verify facts concerning  the
Collateral  in such Pledgor's name, its own name or a  fictitious
name; (f) to endorse checks, drafts, orders and other instruments
for  the  payment of money payable to such Pledgor,  representing
any interest or dividend or other distribution payable in respect
of  the Collateral or any part thereof or on account thereof  and
to  give full discharge for the same; (g) to exercise all rights,
powers  and remedies which such Pledgor would have, but for  this
Agreement,  with  respect to any of the Collateral;  and  (h)  to
carry out the provisions of this Agreement and to take any action


                               10

<Page>

and  execute any instrument which the Pledgee may deem  necessary
or  advisable to accomplish the purposes hereof, and  to  do  all
acts  and  things and execute all documents in the name  of  such
Pledgor or otherwise, deemed by the Pledgee as necessary,  proper
and convenient in connection with the preservation, perfection or
enforcement  of  its rights hereunder.  Nothing herein  contained
shall be construed as requiring or obligating the Pledgee to make
any  commitment  or  to make any inquiry  as  to  the  nature  or
sufficiency of any payment received by it, or to present or  file
any  claim or notice, or to take any action with respect  to  the
Collateral or any part thereof or the moneys due or to become due
in respect thereof or any property covered thereby, and no action
taken  by the Pledgee or omitted to be taken with respect to  the
Collateral  or any part thereof shall give rise to  any  defense,
counterclaim or offset in favor of any Pledgor or to any claim or
action against the Pledgee.  The power of attorney granted herein
is  irrevocable  and coupled with an interest  and  can  only  be
exercised following an Event of Default.

     Section 9.  Pledgee's Duty of Care.  Other than the exercise
of  reasonable care to ensure that safe custody of the Collateral
while being held by the Pledgee hereunder, the Pledgee shall have
no  duty  or liability to preserve rights pertaining thereto,  it
being  understood and agreed that each Pledgor shall  responsible
for preservation of all rights of such Pledgor in the Collateral.
The Pledgee shall be deemed to have exercised reasonable care  in
the  custody and preservation of the Collateral in its possession
if  such Collateral is accorded treatment substantially equal  to
that  which  the  Pledgee  accords its  own  property,  it  being
understood  that  the Pledgee shall not have  responsibility  for
(a)   ascertaining  or  taking  action  with  respect  to  calls,
conversions,  exchanges,  maturities, tenders  or  other  matters
relating to any Collateral, whether or not the Pledgee has or  is
deemed  to  have  knowledge of such matters  or  (b)  taking  any
necessary  steps  to  preserve rights against  any  parties  with
respect to any Collateral.

      Section 10.  Reimbursement of Pledgee.  Each Pledgor agrees
to  pay  upon  demand to the Pledgee the amount of  any  and  all
expenses,  including the fees disbursements and other charges  of
its counsel and of any experts or agents, and its fully allocated
internal costs, that the Pledgee may incur in connection with (a)
any  sale of, collection from, or other realization upon, any  of
the  Collateral, (b) the exercise or enforcement of  any  of  the
rights  of  the  Pledgee hereunder, or (c)  the  failure  by  any
Pledgor  to  perform or observe any of the provisions  hereof  or
otherwise in respect of the Collateral.

      Section 11.  Indemnification.  Each Pledgor agrees to  pay,
indemnify,  and  hold the Pledgee, and each of  their  respective
predecessor,  affiliate,  subsidiaries, successors  and  assigns,
together with their past, present and future officers, directors,
agents, attorneys, financial advisors, representatives, partners,
joint  ventures, affiliates and the successor and assigns of  any
and all of them (each, an "Indemnified Person") harmless from and
against  any  and  all  other liabilities,  obligations,  losses,
damages, penalties, actions, judgments, suits, costs, expenses or
disbursements  of  any  kind or nature  whatsoever  ("Indemnified
Amounts")  brought against or incurred by an Indemnified  Person,
in  any manner arising out of or, directly or indirectly, related
in any way to or connected with this Agreement, including without
limitation, the exercise by the Pledgee of any of its rights  and
remedies  under this Agreement or any other action taken  by  the
Pledgee pursuant to the terms of this Agreement; provided,


                               11

<Page>

however,  a  Pledgor shall have no obligation  hereunder  to  any
Indemnified  Person with respect to Indemnified  Amounts  to  the
extent arising from the gross negligence or willful misconduct of
such  Indemnified  Party, as determined by a court  of  competent
jurisdiction in a final, non-appealable judgment.

     Section 12.  Further Assurances.  Each Pledgor shall, at its
sole  cost and expense, take all action that may be necessary  or
desirable in the Pledgee's sole discretion, so as at all times to
maintain the validity, perfection, enforceability and priority of
the  Pledgee's security interest in the Collateral, or to  enable
the   Pledgee  to  exercise  or  enforce  its  rights  hereunder,
including  without  limitation or otherwise  in  respect  of  the
Collateral.   The Pledgee shall at all times have  the  right  to
exchange the certificates representing such Equity Interests  for
certificates  of  smaller or larger numbers  of  shares  for  any
purpose consistent with this Agreement.

     Section 13.  Securities Act.  In view of the position of the
Pledgors  in  relation to the Collateral,  or  because  of  other
current  or future circumstances, a question may arise under  the
Securities  Act, or any similar Applicable Law hereafter  enacted
analogous in purpose or effect (the Securities Act and  any  such
similar  Applicable  Law as from time to  time  in  effect  being
called  the  "Federal  Securities  Laws")  with  respect  to  any
disposition of the Collateral permitted hereunder.  Each  Pledgor
understands  that  compliance with the  Federal  Securities  Laws
might very strictly limit the course of conduct of the Pledgee if
the  Pledgee were to attempt to dispose of all or any part of the
Collateral  in accordance with the terms hereof, and  might  also
limit  the  extent to which or the manner in which any subsequent
transferee  of  any  Collateral  could  dispose  of   the   same.
Similarly,  there may be other legal restrictions or  limitations
affecting the Pledgee in any attempt to dispose of all or part of
the   Collateral  in  accordance  with  the  terms  hereof  under
applicable  Blue  Sky or other state securities laws  or  similar
Applicable  Law  analogous in purpose or  effect.   Each  Pledgor
recognizes  that  in  light  of the  foregoing  restrictions  and
limitations  the  Pledgee may, with respect to any  sale  of  the
Collateral,  limit the purchasers to those who will agree,  among
other  things, to acquire such Collateral for their own  account,
for investment, and not with a view to the distribution or resale
thereof.   Each Pledgor acknowledges and agrees that in light  of
the  foregoing restrictions and limitations, the Pledgee, in  its
sole  and absolute discretion, may, in accordance with Applicable
Law,  (a)  proceed  to  make  such  a  sale  whether  or  not   a
registration  statement  for  the  purpose  of  registering  such
Collateral  or  part  thereof shall have  been  filed  under  the
Federal  Securities Laws and (b) approach and  negotiate  with  a
single  potential  purchaser to effect such sale.   Each  Pledgor
acknowledges and agrees that any such sale might result in prices
and  other  terms less favorable to the seller than if such  sale
were  a  public sale without such restrictions.  In the event  of
any  such  sale,  the  Pledgee shall incur no  responsibility  or
liability  for  selling  all or any part  of  the  Collateral  in
accordance with the terms hereof at a price that the Pledgee,  in
its  sole  and  absolute  discretion,  may  in  good  faith  deem
reasonable   under   the   circumstances,   notwithstanding   the
possibility  that a substantially higher price  might  have  been
realized  if  the sale were deferred until after registration  as
aforesaid or if more than a single purchaser were approached.


                               12

<Page>

The  provisions  of  this Section will apply notwithstanding  the
existence  of public or private market upon which the  quotations
or  sales prices may exceed substantially the price at which  the
Pledgee sells.

     Section 14.  [Reserved]

      Section  15.  Continuing Security Interest.  This Agreement
shall create a continuing security interest in the Collateral and
shall  remain  in  full force and effect until it  terminates  in
accordance with its terms.

      Section 16.  Security Interest Absolute.  All rights of the
Pledgee  hereunder,  the  grant of a  security  interest  in  the
Collateral  and all obligations of each Pledgor hereunder,  shall
be  absolute  and unconditional irrespective of (a) any  lack  of
validity  or  enforceability of any Loan Document, any  agreement
with  respect  to  any of the Secured Obligations  or  any  other
agreement or instrument relating to any of the foregoing, (b) any
change in the time, manner or place of the payment of, or in  any
other  term  of,  all or any of the Secured Obligations,  or  any
other amendment or waiver of or any consent to any departure from
any  Loan Document, or any other agreement or instrument relating
to   any   of  the  foregoing,  (c)  any  exchange,  release   or
nonperfection  of  any  other  collateral,  or  any  release   or
amendment  or  waiver  of or consent to  or  departure  from  any
guaranty,  for all or any of the Secured Obligations or  (d)  any
other  circumstance  that might otherwise  constitute  a  defense
available  to, or a discharge of, any Pledgor in respect  of  the
Secured  Obligations or in respect of this Agreement (other  than
the indefeasible payment in full of all the Secured Obligations).

      Section 17.  No Waiver.  Neither the failure on the part of
the Pledgee to exercise, nor the delay on the part of the Pledgee
in  exercising  any  right, power or remedy  hereunder,  nor  any
course  of dealing between the Pledgee, on the one hand, and  the
Pledgor,  on  the other hand, shall operate as a waiver  thereof,
nor  shall  any  single or partial exercise of  any  such  right,
power,  or  remedy hereunder preclude any other  or  the  further
exercise  thereof or the exercise of any other  right,  power  or
remedy.

       Section   18.   Notices.   Notices,  requests  and   other
communications required or permitted hereunder shall be given  in
accordance  with, and subject to the provisions of, Section  16.1
of each of the Notes.

      SECTION  19.   GOVERNING  LAW.   THIS  AGREEMENT  SHALL  BE
GOVERNED  BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS  OF  THE
STATE  OF  NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND  TO  BE
FULLY PERFORMED, IN SUCH STATE.

     SECTION 20.  LITIGATION; OTHER MATTERS; WAIVERS.

      (a)   EACH  PARTY HERETO ACKNOWLEDGES THAT ANY  DISPUTE  OR
CONTROVERSY  AMONG ANY OF THE PLEDGORS AND THE PLEDGEE  WOULD  BE
BASED  ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND  WOULD
RESULT IN DELAY AND EXPENSE TO THE PARTIES.  ACCORDINGLY, TO THE


                               13

<Page>

EXTENT  PERMITTED BY APPLICABLE LAW, EACH OF THE PLEDGEE AND  THE
PLEDGORS HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION
OR  PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL  IN
WHICH  AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY  HERETO
ARISING  OUT OF OR RELATING IN ANY WAY TO THIS AGREEMENT  OR  THE
COLLATERAL.

      (b)   EACH  PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM  EXTENT
PERMITTED  BY  APPLICABLE  LAW: (i) ANY CONSTITUTIONAL  OR  OTHER
RIGHT  TO  A  JUDICIAL  HEARING PRIOR TO  THE  TIME  THE  PLEDGEE
DISPOSES OF ALL OR ANY PART OF THE COLLATERAL AS PROVIDED IN THIS
AGREEMENT; (ii) ALL RIGHTS OF REDEMPTION, STAY, OR APPRAISAL THAT
SUCH  PLEDGOR NOW HAS OR MAY AT ANY TIME IN THE FUTURE HAVE UNDER
ANY  APPLICABLE  LAW  NOW  EXISTING  OR  HEREAFTER  ENACTED;  AND
(iii)  EXCEPT  AS  EXPRESSLY REQUIRED  UNDER  THIS  AGREEMENT  OR
APPLICABLE   LAW,   ANY  REQUIREMENT  OF   NOTICE,   DEMAND,   OR
ADVERTISEMENT FOR SALE.

      (c)  THE PROVISIONS OF THIS SECTION HAVE BEEN CONSIDERED BY
EACH   PARTY  WITH  THE  ADVICE  OF  COUNSEL  AND  WITH  A   FULL
UNDERSTANDING  OF  THE  LEGAL  CONSEQUENCES  THEREOF,  AND  SHALL
SURVIVE   THE  PAYMENT  OF  THE  SECURED  OBLIGATIONS   AND   THE
TERMINATION OF THIS AGREEMENT.

      Section  21.   Amendments.  No amendment or waiver  of  any
provision of this Agreement nor consent to any departure  by  any
Pledgor herefrom shall in any event be effective unless the  same
shall  be  in writing and signed by the parties hereto, and  then
such  waiver  or consent shall be effective only in the  specific
instance and for the specific purpose for which given.

      Section 22.  Binding Agreement; Assignment.  This Agreement
shall  be  binding upon and inure to the benefit of  the  parties
hereto  and  their  respective successors and permitted  assigns,
except  that  no  Pledgor  shall  be  permitted  to  assign  this
Agreement or any interest herein or in the Collateral or any part
thereof.

     Section 23.  Termination.  Upon indefeasible payment in full
of   all  of  the  Secured  Obligations,  this  Agreement   shall
terminate.  Upon termination of this Agreement in accordance with
its terms, the Pledgee agrees to take such actions as any Pledgor
may  reasonably request, and at the sole cost and expense of such
Pledgor, to evidence the termination of this Agreement.

       Section   24.   Severability.   Whenever  possible,   each
provision of this Agreement shall be interpreted in such a manner
as  to  be effective and valid under Applicable Law, but  if  any
provision  of  this Agreement shall be prohibited by  or  invalid
under Applicable Law, such provisions shall be ineffective only


                               14

<Page>

to   the  extent  of  such  prohibition  or  invalidity,  without
invalidating  the remainder of such provisions or  the  remaining
provisions of this Agreement.

     Section 25.  Headings.  Section headings used herein are for
convenience only and are not to affect the construction of or  be
taken into consideration in interpreting this Agreement.

      Section  26.  Counterparts.  This Agreement may be executed
in  any number of counterparts, each of which shall be deemed  an
original and all of which shall constitute but one agreement.

     Section 27.  Joint and Several Obligations of Pledgors.  THE
OBLIGATIONS OF THE PLEDGORS HEREUNDER SHALL BE JOINT AND SEVERAL,
AND  ACCORDINGLY, EACH PLEDGOR CONFIRMS THAT IT IS LIABLE FOR THE
FULL  AMOUNT  OF  THE  "SECURED  OBLIGATIONS"  AND  ALL  OF   THE
OBLIGATIONS  AND  LIABILITIES  OF  EACH  OF  THE  OTHER  PLEDGORS
HEREUNDER.

     Section 28.  No Novation.  PRIOR TO THE DATE HEREOF, EACH OF
THE   PLEDGORS   EXECUTED  AND  DELIVERED  THE  EXISTING   PLEDGE
AGREEMENT.   THE  PLEDGORS AND PLEDGEE  ARE  ENTERING  INTO  THIS
AMENDED AND RESTATED PLEDGE AGREEMENT SOLELY TO AMEND AND RESTATE
THE  TERMS  OF, AND THE OBLIGATIONS OWING UNDER AND IN CONNECTION
WITH,  THE EXISTING PLEDGE AGREEMENT.  THE PARTIES DO NOT  INTEND
THIS  AMENDED  AND RESTATED PLEDGE AGREEMENT NOR THE TRANSACTIONS
CONTEMPLATED  HEREBY TO BE, AND THIS AMENDED AND RESTATED  PLEDGE
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY SHALL  NOT  BE
DEEMED  OR  CONSTRUED TO BE, A NOVATION OF ANY OF THE OBLIGATIONS
OWING  BY  ANY  PLEDGOR UNDER OR IN CONNECTION WITH THE  EXISTING
PLEDGE  AGREEMENT.   FURTHER, THE PARTIES AGREE  THAT  (A)  AS  A
RESULT  OF  THE AMENDMENT AND RESTATEMENT OF THE EXISTING  PLEDGE
AGREEMENT  PURSUANT TO THE TERMS HEREOF, THE  LIEN  IN  FAVOR  OF
PLEDGEE  GRANTED  UNDER THE EXISTING PLEDGE  AGREEMENT  SHALL  BE
DEEMED  TO  BE HELD BY PLEDGEE AND (B) THIS AMENDED AND  RESTATED
PLEDGE AGREEMENT, AND THE TRANSACTIONS CONTEMPLATED HEREBY, IN NO
WAY AFFECT THE PERFECTION OR PRIORITY OF ANY SUCH LIEN.
