           rights as holder of the Bills and Notes.

Article 7 (Deductions in Accounts)

      (1)  In cases in which I/we must perform any obligations owed to your
           Bank because they become due or because of acceleration of
           payment or because I/we have assumed the repurchasing
           obligations or because your Bank has acquired the right of
           claiming compensation from me/us or for any other causes, your
           Bank may set off against any such obligations any time any of
           my/our deposits and/or any other credits with your Bank
           irrespective of the due dates of such deposits and/or other
           credits.

      (2)  In cases in which your Bank is able to effect a setoff as
           mentioned in the preceding Paragraph, your Bank may also obtain
           withdrawals from my/our deposits in lieu of my/our doing so, and
           may appropriate any such withdrawals to payments of my/our
           obligations, omitting any advance notice and also not adhering
           to established procedures.

      (3)  In cases in which your Bank makes any deductions in accounts
           according to the provisions of the preceding two Paragraphs,
           interest on my/our credits and obligations, discount charges and
           damages, etc. shall be calculated up to the date on which the
           actual calculation is made by your Bank for the purpose of
           deductions, and the rate of interest and tariffs shall be in
           accordance with those fixed by your Bank; and with regard to the
           foreign exchange rate, the rate quoted at your Bank at the time
           when the actual calculation is made by your Bank shall apply.

Article 7-2 (Ditto)

      (1)  I/We may set of any obligations I/we owe your Bank against
           my/our deposits and/or any other credits with your Bank which
           have become due, even when such obligations have not yet become
           due.

      (2)  When I/we effect a setoff under the provision of the preceding
           Paragraph with regard to the Bills and Notes which your Bank has
           discounted and which have not yet become due, I/we may do so
           upon assuming the repurchasing obligations for the face value of
           the discounted Bills and notes; provided, however, that I/we may
           not effect a setoff with regard to Bills and notes which your
           Bank has discounted and assigned to a third party.

      (3)  With regard to my/our credits or obligations in foreign currency
           or in free yen, I/we may not, notwithstanding the provisions of
           the preceding two Paragraphs, effect a setoff until and unless
           they have become due and procedures required under foreign
           exchange laws and regulations have been completed for them

      (4)  In cases in which I/we effect a setoff under the provisions of
           the preceding three Paragraphs, a notice of the setoff shall be
           made in writing and I/we shall affix my/our seal impression (or
           signature) which has previously been filed with your Bank to the
           certificate or passbook representing my/our deposits and/or
           other credits with your Bank which I/we have set off against
           my/our obligations and submit the same to your Bank forthwith.

      (5)  In cases in which I/we effect a setoff, interest on my/our
           credits and obligations, discount charges and damages, etc.
           shall be calculated up to the date on which my/our notice of the
           setoff arrives at your Bank, and the rate of interest and
           tariffs shall be in accordance with those fixed by your Bank;
           and with regard to the foreign exchange rate, the rate quoted at
           your Bank at the time when the actual calculation is made by
           your Bank for the purpose of setoffs shall apply.  If there is
           an agreement providing for special charges payable when
           obligations are paid prior to their due dates, I/we shall abide
           by such agreement.

Article 8 (Presentment and Delivery of Bills and Notes)

      (1)  In cases in which there exist Bills and Notes pertaining to
           my/our obligations, and your Bank makes deductions in accounts
           as set forth in Article 7 without exercising your Bank's rights
           on the Bills and Notes, your Bank need not simultaneously return
           to me/us any such Bills and Notes.

      (2)  In cases in which there exist Bills and Notes which your Bank
           returns to me/us as a result of deductions in accounts made by
           your Bank or me/us under the preceding two Articles, I/we shall
           appear at your Bank to receive such Bills and Notes without
           delay; provided, however, that if such Bills and Notes have not
           yet become due, your Bank may collect them without returning
           them to me/us.

      (3)  In cases in which your bank makes deductions in accounts as set
           forth in Article 7 by exercising your Bank's rights on the Bills
           and Notes, your Bank need not present nor deliver any such Bills
           and Notes to me/us in the cases enumerated below; and as for
           my/our receiving such Bills and Notes, the provisions of the
           preceding Paragraph shall apply mulatis mutandis:

           1.   When your Bank does not know my/our whereabouts.
           2.   When I/we have designated your bank as the place at which
                Bills and Notes are made payable.
           3.   When it is deemed difficult to dispatch the Bills and
                Notes.
           4.   When it is deemed that presentment or delivery of the Bills
                and Notes can not be made for unavoidable reasons as used
                for collections, etc.

      (4)  In cases in which many of my/our obligations which require
           immediate performance shall exist after a deduction in accounts
           has been effected as provided for in the preceding two Articles,
           and there also exist obligors on the Bills and Notes besides
           me/us, your Bank may retain such Bills and Notes, and after
           collecting or disposing of them, your Bank may appropriate the
           proceeds to the payment of my/our obligations.

Article 9 (Designation of Appropriation)

      In the event I/we made payments or your Bank made deductions in
      accounts as provided for in Article 7, and if in such cases the
      amount of such payments made by me/us or my/our deposits and any
      other credits with your Bank are insufficient to liquidate all of
      my/our obligations, your Bank may appropriate the amount of such
      payments or such deposits and other credits to satisfy my/our
      obligations in such order and in such manner as your Bank deems
      proper and I/we shall raise no objection to such appropriation.

Article 9-2 (Ditto)

      (1)  In the event I/we effect a setoff in accordance with Article 7-
           2, and if in such case my/our deposits and any other credits
           with your bank are insufficient to liquidate all of my/our
           obligations, I/we may appropriate such deposits and other
           credits to satisfy my/our obligations in such order and in such
           manner as I/we designate.

      (2)  In the event I/we fail to designate the order and manner of
           appropriation under the preceding Paragraph, your Bank may
           appropriate my/our deposits and other credits with your Bank to
           satisfy my/our obligations in such order and in such manner as
           your Bank deems proper and I/we shall raise no objection to such
           appropriation.

      (3)  In the event my/our designation under Paragraph (1) is likely to
           interfere with the preservation of your Bank's rights, your Bank
           may, upon lodging an objection thereto without delay,
           appropriate my/our deposits and other credits with your Bank to
           satisfy my/our obligation in such order and in such manner as
           your Bank designates taking into consideration whether or not
           the obligations are secured or guaranteed and if secured or
           guaranteed, the extent of coverage of such security or
           guarantee, the degree of difficulty or disposition of such
           security, their due dates, prospects for settlement of
           discounted Bills and Notes, etc.

      (4)  In case of appropriation by your bank under the preceding two
           Paragraphs, your Bank may designate the order and manner of
           appropriation on the assumption that my/our obligations which
           are in fact not due have become due or that I/we have assumed
           the repurchasing obligations with regard to the Bills and Notes
           which your bank has discounted and which have not yet become due
           or that I/we have assumed in advance the obligations to
           compensate your Bank with regard to the acceptances and
           guarantees.

Article 10 (Assumption of Risks, Hold Harmless Clause, etc.)

      (1)  In cases in which Bills and Notes which I/we have drawn,
           endorsed, accepted, accepted by intervention or guaranteed, or
           instruments which I have furnished to your Bank are lost,
           destroyed, damaged or delayed in arrival due to unavoidable
           circumstances such as incidents, calamities, accidents during
           transit, etc., I/we shall pay my/our obligations as recorded on
           your Bank's books, vouchers, etc.: and further, upon your Bank's
           demand, I/we shall forthwith furnish your bank with substitute
           Bills and Notes or instruments.  I/We shall make no claim
           whatsoever against your Bank with regard to losses and damages
           arising in such cases.

      (2)  In cases in which security which I/we have furnished to your
           Bank is lost or damaged due to unavoidable circumstances as set
           forth in the preceding Paragraph, I/we shall make no claim
           whatsoever against your Bank.

      (3)  Even if your Bank's rights on Bills and Notes are ineffective
           due to lack of legal requirements in the Bills and Notes, or due
           to invalidating entries thereon, or if your Bank's rights on the
           Bills and Notes lapse due to inadequacy in the procedures for
           preservation of your bank's rights, I/we shall be liable for the
           face value of such Bills and Notes.

      (4)  In transactions in which your bank has deemed my/our seal
           impression (or signature) genuine after checking with reasonable
           care the seal impression (or signature) on Bills and Notes or
           instruments against my/our seal impression (or specimen
           signature) filed with your Bank, I/we shall bear any losses and
           damages arising from forgery, alteration, wrongful use of Bills
           and Notes, instruments or seals (or signatures), and shall be
           liable in accordance with the terms of any such Bills and Notes
           or instruments.

      (5)  I/We shall bear the expenses incurred in exercising or
           preserving your Bank's rights against me/us, or in collecting or
           disposing of any security; and I/we shall also bear any expenses
           required in the event I/we request your Bank to cooperate with
           me/us for the preservation of my/our rights.

Article 11 (Changes in Matters Filed)

      (1)  In cases of a change in the matters filed with your Bank such as
           my/our seal (or signature), name, trade name, representative,
           address, etc., I/we shall forthwith notify your Bank thereof in
           writing.

      (2)  In case any notice given by your Bank or any documents, etc.
           dispatched by your Bank are delayed or fail to reach me/us
           because of my/our failure to notify your bank in accordance with
           the preceding Paragraph, the notice or documents, etc. shall be
           deemed to have arrived at the time they normally should have
           arrived.

Article 12 (Report and Investigation)

      (1)  Upon your Bank's demand, I/we shall forthwith submit to your
           Bank reports pertaining to my/our assets and liabilities,

           occur pertaining to my/our assets and liabilities, management or

           reports thereof even in the absence of your Bank's demand.
