      (e) 

      (f) The Bank
may, in its name, or in the name of the Grantor:  (i) execute and file
financing statements under the UCC or any other filings or notices necessary or
desirable to create, perfect or preserve its security interest, all without
notice (except as required by applicable law and not waivable) and without
liability except to account for property actually received by it; (ii) demand,
sue for, collect or receive any money or property at any time payable or
receivable on account of or in exchange for, or make any compromise or
settlement deemed desirable with respect to, any item of the
Collateral  (but shall be under no obligation to do so); (iii) make
any notification (to the issuer of any certificate or security, or otherwise, or

security interest  or any enforcement of remedies, and retain any
documents evidencing the title of the Grantor to any item of the Collateral; and
(iv) issue entitlement orders with respect to any of the
Collateral.

      

      The Grantor agrees that it will not

Collateral or any financing or like statement with respect to the Collateral in
which the Bank is not named as the sole secured party except in connection with
Permitted Liens or consent or be a party to any Account Control Agreement with
respect to any Collateral to which the Bank is not a party.  At the
request of the Bank the Grantor agrees to do all other things which the Bank may
deem necessary or advisable in order to perfect and preserve its security
interest, perfection and operational control and to give effect to the rights
granted to the Bank under this Agreement or enable the Bank to comply with any
applicable laws or regulations.  Notwithstanding the foregoing, the
Bank does not assume any duty with respect to the Collateral and is not required
to take any action to collect, preserve or protect its or the Grantor’s rights
in any item of the Collateral.  The Grantor releases the Bank and
agrees to hold the Bank harmless from any claims, causes of action and demands
at any time arising with respect to this Agreement, the use or disposition of
any item of the Collateral or any action taken or omitted to be taken by the
Bank with respect thereto, except, in each case, for claims, causes of action
and demands arising from (i) Bank’s gross negligence or willful misconduct or
(ii) Bank’s obligations as a secured party under this Agreement or under
applicable law.

      

      4. Currency Conversion. For calculation
purposes, any currency in which the Collateral is denominated (the “Collateral Currency”)
will be converted into the currency of the Liabilities (the “Liability Currency”)
at the spot rate of exchange for the purchase of the Liability Currency with the
Collateral Currency quoted by the Bank at such place as the Bank deems
appropriate (or, if no such rate is quoted on any relevant date, estimated by
the Bank on the basis of the Bank’s last quoted spot rate) or another prevailing
rate that the Bank deems more appropriate.

      

      5. Remedies.

      

      Upon the occurrence and during the
continuance of a Default, the Bank will have the rights and remedies under the
UCC and the other rights granted to the Bank under this Agreement and may
exercise its rights without regard to any premium or penalty from liquidation of
any Collateral and without regard to the Grantor’s basis or holding period for
any Collateral.

      

      The Bank may sell in the Borough of
Manhattan, New York City, or elsewhere, in one or more sales or parcels, at the
price as the Bank deems best, for cash or on credit or for other property, for
immediate or future delivery, any item of the Collateral, at any broker’s board
or at public or private sale, in any reasonable manner permissible under the UCC
(except that, to the extent permissible under the UCC, the Grantor waives any
requirements of the UCC) and the Bank or anyone else may be the purchaser of the
Collateral and hold it free from any claim or right including, without
limitation, any equity of redemption of the Grantor, which right the Grantor
expressly waives.

      

      The Bank may also, in its sole
discretion: (i) convert any part of the Collateral Currency into the Liability
Currency;  (ii) hold any monies or proceeds representing the
Collateral in a cash collateral account in the Liability Currency or other
currency that the Bank reasonably selects; (iii) invest such monies or proceeds
on behalf of the Grantor; and (iv) apply any portion of the Collateral, first,
to all costs and expenses of the Bank, second, to the payment of interest on the
Liabilities and any fees or commissions to which the Bank may be entitled,
third, to the payment of principal of the Liabilities, whether or not then due,
and fourth, to the Grantor.

      

      The Grantor will pay to the Bank all
expenses (including attorneys’ fees and legal expenses incurred by the Bank and
the allocated costs of its in-house counsel) in connection with the exercise of
any of the Bank’s rights or obligations under this Agreement or the
Note.  The Grantor will take any action requested by the Bank to allow
it to sell

      or
dispose of the Collateral.  Notwithstanding that the Bank may continue
to hold Collateral and regardless of the value of the Collateral, the Grantor
will remain liable for the payment in full of any unpaid balance of the
Liabilities.

      

      

      6. Jurisdiction.

      

      To the maximum extent not prohibited by
applicable law, the Grantor hereby irrevocably: (i) submits to the jurisdiction
of any New York state or United States federal court sitting in New York City
over any action or proceeding arising out of this Agreement;(ii) agrees that all
claims in respect of such action or proceeding may be held and determined in
such New York state or federal court;  (iii) agrees that any action or
proceeding brought against the Bank may be brought only in a New York state or
United States federal court sitting in New York county;  (iv) consents
to the service of process in any such action or proceeding in either of said
courts by mailing thereof by the Bank by registered or certified mail, postage
prepaid, to the Grantor at its address specified on the signature page hereof,
or at the Grantor’s most recent mailing address as set forth in the records of
the Bank; and (v) waives any defense on the basis of inconvenient
forum.

      

      The Grantor agrees that a final
judgment in any such action or proceeding shall be conclusive and may be
enforced in any other jurisdiction by suit or proceeding in such
state.  Nothing herein shall affect the right of the Bank to serve
legal process in any other manner permitted by law or affect the right of the
Bank to bring any action or proceeding against the Grantor or its property in
the courts of any other jurisdiction.

      

      7. Waiver of Jury
Trial.  THE UNDERSIGNED AND THE BANK EACH WAIVE ANY RIGHT TO
JURY TRIAL.

      

      8. Notices. Unless otherwise agreed
in writing, notices may be given to the Bank and the Grantor at their telecopier
numbers (confirmed by telephone to their telephone numbers) or addresses listed
on the signature page of this Agreement, or such other telecopier (and
telephone) number or addresses communicated in writing by either party to the
other.  Notices to the Bank are effective on receipt.

      

      9. Miscellaneous.

      

      (a) This
Agreement shall be binding on the Grantor and its successors and assigns and
shall inure to the benefit of the Bank and its successors and assigns, except
that the Grantor may not delegate any of its obligations hereunder without the
prior written consent of the Bank.

      

      (b) No
amendment or waiver of any provision of this Agreement nor consent to any
departure by the Grantor will be effective unless it is in writing and signed by
the Grantor and the Bank and will be effective only in that specific instance
and for that specific purpose.  No failure on the part of the Bank to
exercise, and no delay in exercising, any right will operate as a waiver or
preclude any other or further exercise or the exercise of any other
right.

      

      (c) The
rights and remedies in this Agreement are cumulative and not exclusive of any
rights and remedies which the Bank may have under law or under other agreements
or arrangements with the Grantor or any other party (including, without
limitation, any Account Control Agreement).

      

      (d) The
provisions of this Agreement are intended to be severable.  If for any
reason any provision of this Agreement is not valid or enforceable in whole or
in part in any jurisdiction, that provision will, as to that jurisdiction, be
ineffective to the extent of that invalidity or unenforceability without in any
manner affecting the validity or enforceability in any other jurisdiction or the
remaining provisions of this Agreement.

      

      (e) The
Grantor hereby waives presentment, notice of dishonor and protest of all
instruments included in or evidencing the Liabilities or the Collateral and any
other notices and demands, whether or not relating to those
instruments.
