      offered rates for deposits in United States Dollars having a one month maturity,
      which appear on the Reuters Screen LIBO Page as of 11:00 A.M., London time,
      on such LIBOR Determination Date.  Such posted offered rates are for
      value on the second Business Day after which dealings in deposits in United
      States Dollars are transacted in the London interbank market.  If at
      least two such offered rates appear on the Reuters Screen LIBO Page, the rate
      in
      respect of such LIBOR Determination Date will be the arithmetic mean (rounded,
      if necessary, to the nearest one hundred-thousandth of a percent) of such
      offered rates as determined by the Master Trust Trustee.  If fewer
      than two offered rates appear, LIBOR in respect of such LIBOR Determination
      Date
      will be determined as if the parties had specified the rate described in (ii)
      below.





(ii)           On
      any LIBOR Determination Date on which fewer than two offered rates appear on
      the
      Reuters Screen LIBO Page as specified in (i) above, LIBOR will be
      determined on the basis of the rates at which deposits in United States Dollars
      are offered by the Reference Banks at approximately 11:00 A.M., London
      time, on such LIBOR Determination Date to prime banks in the London interbank
      market, having a one month maturity, such deposits commencing on the second
      Business Day immediately following such LIBOR Determination Date and in a
      principal amount of not less than U.S. $1,000,000 that is representative for
      a
      single transaction in such market at such time.  The Master Trust
      Trustee will request the principal London office of each of such Reference
      Banks
      to provide a quotation of its rate.  If at least two such quotations
      are provided,  LIBOR in respect of such LIBOR Determination Date will
      be the arithmetic mean (rounded, if necessary, to the nearest one
      hundred-thousandth of a percent) of such quotations.  If fewer than
      two quotations are provided, LIBOR in respect of such LIBOR Determination Date
      will be the arithmetic mean (rounded, if necessary, to the nearest one
      hundred-thousandth of a percent) of the rates quoted by three major banks in
      The
      City of New York selected by the Master Trust Trustee at approximately
      11:00 A.M., New York City time, on such LIBOR Determination Date for loans
      in United States Dollars to leading European banks, having a one month maturity,
      such loans commencing on the second Business Day immediately following such
      LIBOR Determination Date and in a principal amount of not less than U.S.
      $1,000,000 that is representative for a single transaction in such market at
      such time, provided, however, that if the banks in The City of New York selected
      as aforesaid by the Master Trust Trustee are not quoting as mentioned in this
      sentence, LIBOR with respect to such LIBOR Determination Date will be LIBOR
      in
      effect immediately prior to such LIBOR Determination Date.

      power

      cause to be deposited in the Spread Account an amount equal to the lesser of
      (A)
      the Projected Spread as of the immediately preceding Transfer Date and (B)
      the
      amount of funds on deposit in the 1990 Trust Spread Account multipliedby
      a fraction, the numerator
      of which is the Projected Spread as of the immediately preceding Transfer Date,
      and the denominator of which is the projected spreads as of the immediately
      preceding Transfer Date for all outstanding Series which have spread

(iii)                      On
      any Transfer Date related to a Due Period commencing after the 1990 Trust

      is greater than the Projected Spread on such Transfer Date, the Servicer shall
      withdraw the amount of such excess from the Spread Account and allocate and
      pay
      such excess to the Seller.





(iv)                      Upon
      the commencement of and during an Early Amortization Period, the Master Trust
      Trustee will deposit all funds in the Spread Account into the Liquidity Reserve

      Deposit Account bearing a designation clearly indicating that the funds
      deposited therein are held for the benefit of the Seller (the "Liquidity Reserve
      Account").  The Seller shall possess all right, title and interest in
      all funds on deposit from time to time in the Liquidity Reserve Account and
      in
      all proceeds thereof; provided, however,
      that no funds on
      deposit in the Liquidity Reserve Account shall be paid to the Seller if such
      payment would reduce the funds in such account below an amount equal to the
      Available Subordinated Amount.  Pursuant to authority granted to it
      pursuant to Section 3.01(b) of the Agreement, the Servicer shall have the
      revocable power to instruct the Master Trust Trustee to withdraw funds from
      the
      Liquidity Reserve Account for the purpose of fulfilling the obligations of
      the
      Seller under this Series Supplement and the Agreement.  The Servicer

      such excess to the Seller.

      ceases to be an Eligible Deposit Account, the Master Trust Trustee (or the
      Servicer on its behalf) shall upon the earlier of (a) 30 calendar days, or
      (b)
      the next Determination Date, establish a new Series 1997-1 Account meeting

      any
      right to withdraw any amount from, any Series 1997-1 Account, except as

      apply available funds from the following sources in the following order of
      priority in the same manner as Available Certificateholder Interest Collections,
      each of which applications shall reduce such Deficiency Amount (all such

      Date) and the Deficiency Amount for such Transfer Date (as reduced by the
      applications required by Section 4.05 of this Series Supplement) is greater
      than
      zero, the Invested Amount shall be reduced by the lesser of (i) such remaining
      Deficiency Amount for such Transfer Date and (ii) the amount of Investor Dealer
      Note Losses for the related Due Period remaining unreimbursed after all

(iii)                      During
      the Revolving Period or the Accumulation Period, Series 1997-1 Shared Seller
      Principal Collections, if any, and shared seller principal collections for
      any
      other Series that provides for shared seller principal collections shall be
      determined on each business day and allocated in the following
      priority:  (i) to the 1997-1 Series to the extent of any Series 1997-1
      Accumulation Period Principal Shortfall and to any other Series to the extent
      such Series provides for the use of shared seller principal collections in
      respect of principal shortfalls, (ii) to the Excess Funding Account to the
      extent necessary to maintain the Master Trust Seller’s Interest at an amount
      equal to (or, in the discretion of the Seller, greater than) the Minimum Master
      Trust Seller’s Interest and (iii) to the Seller.  If shared seller
      principal collections for all Series, including Series 1997-1 Shared Seller
      Principal Collections, are less than the shortfalls for which shared seller
      principal collections may be used, including any Series 1997-1 Accumulation
      Period Principal Shortfall, then such shared seller principal collections will
      be allocated to all such shortfalls, including any Series 1997-1 Accumulation
      Period Principal Shortfall, pro rata based on the
      relative amounts of each such shortfall.





(iv)                      “Series
      1997-1 Shared Seller Principal Collections” means on each business day (i)

      Excess Seller’s Principal Collections and (ii) during an Accumulation Period,
      all Remaining Available Seller’s Principal Collections and all Excess Seller’s
      Principal Collections.  There shall be no Series 1997-1 Shared Seller
      Principal Collections during any Early Amortization Period.





(e)           If
      on any Distribution Date during an Early Amortization Period after the
      application of all funds to be allocated or distributed on such date the excess,
      if any, of (x) the Invested Amount over (y) the amount in the Series Principal
      Account (the “Early Amortization Period Shortfall Amount”) is less than or equal
      to the aggregate amount of funds contained in the Liquidity Reserve Account
      then
      funds shall be withdrawn in an amount equal to the Early Amortization Period
      Shortfall Amount and shall be deposited in the Series Principal
      Account.

      IV.9  Shared
      Principal Collections.





(a)           That

      Principal Collections pursuant to Section 4.08(b) and otherwise will be
      deposited in the Excess Funding Account to the extent necessary to maintain
      the
      Master Trust Seller's Interest at an amount equal to (or, in the discretion
      of
      the Seller, greater than) the Minimum Master Trust Seller's Interest or
      allocated to the Seller..

(b)           "Series
      1997-1 Shared Principal Collections," with respect to any Business Day
      commencing after the 1990 Trust Termination Date, shall mean an amount equal
      to
      the Series 1997-1 Principal Shortfall for such Business Day; provided, however,
      that, if the
      aggregate amount of Shared Principal Collections for all Series for such
      Business Day is less than the aggregate amount of Principal Shortfalls for
      all
      Series for such Business Day, then Series 1997-1 Shared Principal Collections
      for such Business Day shall equal the product of (x) Shared Principal
      Collections for all Series for such Business Day and (y) a fraction, the
      numerator of which is the Series 1997-1 Principal Shortfall for such Business
      Day and denominator of which is the aggregate amount of Principal Shortfalls
      for
      all Series for such Business Day.





SECTION
      IV.10  Distributions to
­Series
      1997-1 Certificateholders.  On each Transfer Date, after all
      allocations to the Distribution Account and the Series Principal Account for
      the
      related Transfer Date have been made, the Master Trust Trustee, acting in
      accordance with instructions from the Servicer, shall transfer to the
      Distribution Account the funds on deposit in the Series Principal Account and
      shall make, without duplication, the following distributions from the
      Distribution Account:





(a)           Interest
      Distributions.  On each Distribution Date (including the
      Expected Payment Date), Monthly Interest will be distributed to the Series
      1997-1 Certificateholders as accrued interest on the 1997-1
      Certificates.  To the extent any interest is due but not distributed
      on any such Distribution Date, such amount will be distributed on the following
      Distribution Date, along with, to the extent permitted by law, interest at
      the
      Certificate Rate on such amount.





(b)           Expected
      Payment
      Date.  On the Expected Payment Date, in addition to the amount
      described in (a) above, amounts on deposit in the Series Principal Account
      will
      be distributed as principal (up to a maximum of the Invested Amount on such
      Distribution Date) on the Series 1997-1 Certificates.





(c)           Early
      Amortization
      Period.  On each Distribution Date related to a Due Period
      occurring during an Early Amortization Period, in addition to the amount
      described in (a) above, amounts on deposit in the Series Principal Account
      will
      be distributed as principal (up to a maximum of the Invested Amount on such
      Distribution Date) on the Series 1997-1 Certificates.





SECTION
      IV.11  Accumulation Period
      Length;
      Accumulation Period Commencement Date.  On or prior to the
      first Due Period which is nine months prior to the Due Period related to the
      Distribution Date which is the Expected Payment Date, the Servicer shall
      determine in its sole discretion the Accumulation Period Length and the
      Accumulation Period Commencement Date and, promptly following such
      determination, the Servicer shall notify the Master Trust Trustee and the Rating
      Agencies in writing of such determination.





E-353


SECTION
      IV.12   Partial Month Due
      Period.  The allocation and distribution provisions in this
      Series Supplement are based upon the assumptions that each Due Period will
      be a
      calendar month and that each Due Period will have a unique related Transfer
      Date
      and Distribution Date.  However, under certain circumstances (such as
      the occurrence of an Early Amortization Event, the Revolving Period could end
      on
      a date other than the last day of a calendar month (the period from the first
      day of such month (the "Subject Month") to and including the date of such
      occurrence being referred to herein as the "Revolving Due Period"), and an
      Early
      Amortization Period could commence on a date other than the first day of a
      calendar month (the period from such other date until the last day of the
      Subject Month being the "Amortizing Due Period").  If such a
      circumstance occurs, then the Servicer, the Seller and the Master Trust Trustee
      shall observe the following rules:





(i)           the
      Transfer Date for both the Revolving Due Period and the Amortizing Due Period
      shall be the date on which the Transfer Date would have occurred if the Subject
      Month had been an ordinary Due Period;





(ii)           the
      allocations and distributions of Finance Charge Collections (and all items
      derived from Finance Charge Collections, such as Available Certificateholder
      Interest Collections and Available Seller's Finance Charge Collections) and
      Dealer Note Losses occurring during the Subject Month shall be made as if the
      Subject Month were one Due Period, without any distinction between the Revolving
      Due Period and the Amortizing Due Period; and





(iii)           two
      separate sets of allocations and distributions of Principal Collections (and
      all
      items derived from Principal Collections, such as Investor Principal Collections
      and Seller's Principal Collections) shall be made on such Transfer Date,
      according to whether such Principal Collections were received during the
      Revolving Due Period (in which case allocations and distributions shall be
      made
      as provided in Sections 4.08(a) and (c)) or the Amortizing Due Period (in which
      case allocations and distributions shall be made as provided in Sections 4.08(b)
      and (d)).

SECTION
      IV.13  Additional Rights
      upon the
      Occurrence of Certain Events.  Notwithstanding the provisions
      of Section 9.02(a) of the Agreement, if any insolvency event occurs with respect
      to the Seller, Navistar International Corporation, Navistar International
      Transportation Corporation or Navistar Financial Corporation on the day of
      such
      insolvency event, the Seller will (subject to the actions of the
      Certificateholders) immediately cease to transfer Dealer Notes to the 1990
      Trust
      or the Master Trust, as applicable, and promptly give notice to the Master
      Trust
      Trustee of such insolvency event.  Under the terms of the Pooling and
      Servicing Agreement, if an insolvency event occurs with respect to the Seller
      after the 1990 Trust Termination Date but prior to the date on which the Series
      1995-1 investor certificates issued by the Master Trust have been paid in full,
      then within 15 days the Master Trust Trustee will publish a notice of such
      insolvency event stating that the Master Trust Trustee intends to sell,
      liquidate or otherwise dispose of the Dealer Notes in a commercially reasonable
      manner and on commercially reasonable terms, unless within a specified period
      of
      time Certificate holders representing more than 50% of the aggregate series
      invested amount of the certificates of each such Series and each person holding
      a Supplemental Certificate, instruct the Master Trust Trustee not to sell,
      dispose of or otherwise liquidate the Dealer Notes and to continue transferring
      Dealer Notes as before such insolvency event.





SECTION
      IV.14  Voting of the Master
      Trust’s
      Interests in the 1990 Trust.  The Master Trust Trustee will
      have the right, without the consent of the Certificateholders, to vote, or
      to
      consent or withhold consent with respect to, the Class A-5 Investor Certificate
      and any other Investor Certificate on any matter for which votes or consents
      are
      solicited under the 1990 Trust Agreement, provided that such action will not,
      as
      evidenced by an officer’s certificate of the Servicer, have a material adverse
      effect on the Certificateholders of any Series.  The Master Trust
      Trustee will also have the right, with the consent of the Applicable Voting
      Percentage of the Certificateholders, to vote, or to consent or withhold
      consent, with respect to the Class A-5 Investor Certificate and any other
      Investor Certificate on any matter for which votes or consents are solicited
      under the 1990 Trust Agreement.





“Applicable
      Voting Percentage” means, with respect to any matter for which votes or consents
      are solicited under the 1990 Trust Agreement, the percentage of votes or
      consents of the Investor Certificates needed to pass the proposed
      matter.
