                 Pursuant to Section 2.02(a) of the Indenture


A.   Pursuant  to  Section 2.02(a)  of the  Indenture,  dated as of October 7,

     Donald E. Kiernan, Vice President,  and Roger W. Wohlert,  Treasurer,  do
     hereby  certify that there is hereby  established  a Series (as that term

     1.  The title of the Securities of the Series is "Medium-Term Notes, Series
         A, Due Nine Months or More From Date of Issue" (the "Notes").

     2.  The limit upon the aggregate principal amount of the Notes which may be
         authenticated  and  delivered  under the  Indenture  (except  for Notes
         authenticated and delivered upon transfer of, or in exchange for, or in
         lieu of, other Notes pursuant to Section 2.08, 2.09, 2.12, 3.06 or 9.05
         of the Indenture) is U.S. $1,750,000,000.

         Company  designated  by  resolution  of the Board of Directors or the
         delegate  of any  such  officer  (each  of  the  foregoing  being  an
         "Authorized  Officer")  from  time  to  time,  as  evidenced  by  the
         settlement instructions (the "Settlement  Instructions") furnished by
         the  Company  from  time  to  time  to  the  Trustee,   by  facsimile
         transmission  or  in  written  schedules,   in  each  case  providing
         substantially the information contained in Schedule A hereto.







                                     -2-

     4.  The rate or rates,  or the method of  determining  the rate or rates,
         at which each of the Notes shall bear  interest  shall be  determined
         and  established  by an  Authorized  Officer  from  time to time,  as
         evidenced by the  Settlement  Instructions,  and shall  include those
         methods  set forth in the  prospectus,  dated  October  23,  1997,  a
         prospectus  supplement,  dated October 23, 1997, and any amendment or
         supplement thereto  (collectively,  the "Prospectus") relating to the
         Notes.  Each Note will bear interest from its issue date,  or, in the
         case of Notes issued upon transfer or exchange,  from the most recent
         Interest  Payment  Date  (as  defined  in the  Prospectus)  to  which
         payment of  interest  has been made or duly  provided  for.  Interest
         will  be  payable  to  the  person  in  whose  name a  Note  (or  any
         Predecessor  Note) is  registered  at the  close of  business  on the
         Record Date next  preceding  the  Interest  Payment  Date;  provided,
         however,  that interest  payable at maturity and upon redemption will
         be payable to the person to whom principal  shall be payable.  Unless
         otherwise  determined by an Authorized  Officer,  as evidenced by the
         Settlement  Instructions,   the  Interest  Payment  Dates  for  Notes
         bearing  interest  at a fixed  rate  ("Fixed  Rate  Notes")  shall be
         February  1 and  August 1 of each  year,  and the  Record  Date  with
         respect to any  Interest  Payment Date shall be the date fifteen (15)
         calender days  immediately  preceding such Interest Payment Date. The
         Interest   Payment  Dates  for  Notes  bearing  interest  at  a  rate
         determined by reference to an interest rate formula  ("Floating  Rate
         Notes") shall be determined and  established on behalf of the Company
         by an  Authorized  Officer  from time to time,  as  evidenced  by the
         Settlement   Instructions.   Unless   otherwise   determined   by  an
         Authorized Officer, as evidenced by the Settlement Instructions,  the
         Record Date with  respect to any  Interest  Payment Date for Floating
         Rate Notes shall be the date fifteen (15) calender  days  immediately
         preceding   such   Interest   Payment   Date.   Notwithstanding   the
         foregoing,  the first  payment  of  interest  on any Note  originally
         issued  between a Record  Date and an Interest  Payment  Date will be
         made on the  Interest  Payment  Date  following  the next  succeeding
         Record  Date and will be payable to the person to whom the Note shall
         have been issued.

     5.  Interest   (other  than   interest   payable  at  maturity  and  upon
         redemption)  on Notes in  definitive  form  will be paid by check and
         mailed to the  address of the person  entitled  thereto as it appears
         in the Security  Register.  Notwithstanding  the foregoing,  a holder
         of U.S.  $10,000,000 or more in aggregate  principal  amount of Notes
         of like  tenor and term (or a holder of the  equivalent  thereof in a
         specified  currency  other than U.S.  dollars)  shall be  entitled to
         receive such interest  payments in immediately  available  funds, but
         only if  appropriate  instructions  have been  received in writing by
         the  Paying  Agent  on  or  prior  to  the  applicable  Record  Date.
         Interest   (other  than   interest   payable  at  maturity  and  upon
         redemption)  on Notes in global form will be paid by wire transfer to
         The  Depository  Trust Company or its nominee in accordance  with the
         Medium-Term  Notes,   Series  A,   Administrative   Procedures.   The
         principal,  premium,  if any,  and  interest  due at maturity or upon
         redemption,  as the case may be, on the Notes shall be payable at the
         office  or  agency  of  the  Company  maintained  in the  Borough  of
         Manhattan,  the city of New York for that purpose and will be made in
         immediately  available funds, provided that such Note is presented to
         the Paying Agent in time for the Paying  Agent to make such  payments
         in such funds in accordance with its normal procedures.

     6.  If  an  Initial  Redemption  Date  for a  Note  is  determined  by an
         Authorized  Officer,  as  evidenced in any  Settlement  Instructions,
         such Note  shall be  redeemable  at the  option of the  Company on or
         after a specified  date prior to maturity on at least  30 days',  but
         not more  than  60 days',  notice to the  holders  of such  Note,  at
         prices  declining  from par or a  specified  premium  to par  after a
         later  date,  together  with  the  accrued  interest  to the  date of
         redemption,  all as may be determined by an  Authorized  Officer,  as
         evidenced by the Settlement Instructions.





     7.  There is no obligation of the Company to redeem,  repay or purchase the
         Notes  pursuant to any sinking fund or analogous  provision,  or at the
         option of a holder thereof.

     8.  Unless  otherwise  specified in the  Prospectus,  Notes shall be issued
         only in registered form in minimum denominations of U.S. $1,000 and any
         amount in excess  thereof that is an integral  multiple of U.S.  $1,000
         or, in the case of Notes denominated in a Specified Currency other than
         U.S. dollars, the authorized denominations set forth in the Prospectus.

     9.  The  Notes  shall be  issued  in  fully  registered  form and  shall be
         represented by either a global certificate  registered in the name of a
         nominee  of The  Depository  Trust  Company or other  depository,  or a
         certificate issued in definitive form, as specified in the Prospectus.

     10. Unless otherwise specified in the Prospectus,  the Company will not pay
         any  additional  amounts  on Notes  held by a person  who is not a U.S.
         person in respect of taxes or similar charges withheld or deducted.

     11. The Notes shall be denominated,  and principal of and premium,  if any,
         and interest on the Notes shall be payable, in U.S. dollars or in other
         applicable  currencies or currency units,  including  European Currency
         Units.

     12. Payments of interest on the Notes may be determined  with  reference to
         an index,  determined  by an  Authorized  Officer,  as evidenced by the
         Settlement Instructions.

     13. Any other terms of the Notes  (which  terms  shall not be  inconsistent
         with this  Officers'  Certificate  or the  provisions of the Indenture)
         shall be determined and established by an Authorized  Officer from time
         to time,  as evidenced by the  Settlement  Instructions,  including any
         changes to the terms set forth in the forms of the Fixed Rate Notes and
         the  Floating  Rate  Notes,   attached  hereto  as  Annex  B,  and  the
         Prospectus, attached hereto as Annex C.

B.   The forms of the Fixed  Rate Notes and the  Floating  Rate Notes are hereby
     approved in the form attached as Annex B.

C.   Each of the undersigned has read the Indenture,  including the provisions
     of  Section 2.02   and  the  definitions   relating   thereto,   and  the
     Resolutions.  In the  opinion  of each of the  undersigned,  he has  made
     such  examination  or  investigation  as is  necessary  to enable  him to
     express an  informed  opinion  as to  whether  or not all the  conditions
     precedent  provided in the Indenture relating to the establishment of the
     form and terms of a Series of Securities under the Indenture,  designated
     as the Notes in this Officers'  Certificate,  have been complied with. In
     the opinion of the undersigned,  all such conditions  precedent have been
     complied with.









     IN WITNESS WHEREOF,  the undersigned have hereunto  executed this Officers'
Certificate as of the 23rd day of October 1997.
