Association hereby accepts such appointment.  The Calculation Agent shall act as
an agent of the Issuer for the purpose of determining the interest rate or rates
of the Floating Rate Notes.

the issuance of any Floating Rate Notes, copies of the proposed forms of such
Notes, including copies of all terms and conditions relating to the
determination of the interest rate thereunder.  The Issuer shall not issue any
Floating Rate Note prior to the receipt of confirmation from the Calculation
Agent of its acceptance of the proposed form of such Note.  The Calculation
Agent hereby acknowledges its acceptance of the proposed form of Floating Rate
Note previously delivered to it.

which may be made against it in connection with its appointment or the exercise
of its powers and duties hereunder as well as the reasonable costs, including

     pursuant to paragraph 3 above;

          (v)   the Calculation Agent, whether acting for itself or in any other

successor Calculation Agent. The Issuer covenants that it shall appoint a
successor Calculation Agent as soon as practicable after receipt of any notice
of resignation hereunder. Upon its resignation or removal becoming effective,

administrator or other similar official of the Calculation Agent or of all or
any substantial part of its property shall be appointed, or if any order of any
court shall be entered approving any petition filed by or against the
Calculation Agent under the provisions of any applicable bankruptcy or
insolvency law, or if any public officer shall take charge or control of the
Calculation Agent or its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then a successor Calculation Agent shall be
appointed by the Issuer by an instrument in writing filed with the successor
Calculation Agent and the Trustee. Upon the appointment as aforesaid of a
successor Calculation Agent and acceptance by the latter of such appointment the
former Calculation Agent shall cease to be Calculation Agent hereunder.

          (d)  Any successor Calculation Agent appointed hereunder shall execute
and deliver to its predecessor, the Issuer and the Trustee an instrument
accepting such appointment hereunder, and thereupon such successor Calculation
Agent, without any further act, deed or conveyance, shall become vested with all
the authority, rights, powers, immunities, duties and obligations of such
predecessor with like effect as if originally named as the Calculation Agent
hereunder, and such predecessor, upon payment of its compensation, charges and
disbursements then unpaid, shall thereupon become obliged to transfer and
deliver, and such successor Calculation Agent shall be entitled to receive,
copies of any relevant records maintained by such predecessor Calculation Agent.

          (e)  Any corporation into which the Calculation Agent may be merged or
converted or any corporation with which the Calculation Agent may be
consolidated or any corporation resulting from any merger, conversion or
consolidation to which the Calculation Agent shall be a party shall, to the
extent permitted by applicable law, be the successor Calculation Agent under
this Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto.  Notice of any such merger, conversion
or consolidation shall forthwith be given to the Issuer and the Trustee.
