                                         August __, 1996



 To the Persons Listed on
  Annex I Hereto

 Ladies and Gentlemen:

          We have acted as special New York counsel to the financial
 institutions listed on Schedule A-1 to this opinion letter (the "Foreign
 Liquidity Lenders") and to the financial institutions listed on Schedules A-2,
 A-3 and A-4 to this opinion letter (the "Domestic Liquidity Lenders"), in
 connection with the execution and delivery by certain branches of the Foreign
 Liquidity Lenders listed on Schedules A-5, A-6 and A-7 of this opinion letter
 (each of such branches being hereinafter referred to as a "Foreign Liquidity
 Branch") and by the Domestic Liquidity Lenders of the Second Amendment and
 Consent dated as of August __, 1996 (the "Amendment") among Case Equipment Loan
 Trust 1994-B, a Delaware business trust (the "Issuer"), the financial
 institutions parties thereto, including the Foreign Liquidity Lenders acting
 through their respective Foreign Liquidity Branches, and the Domestic Liquidity
 Lenders (the "Lenders") and The Chase Manhattan Bank, as administrative agent
 (the "Administrative Agent"), amending a Liquidity Agreement dated as of June
 23, 1994 (as amended, the "Liquidity Agreement") among the Issuer, the
 financial institutions parties thereto and the Administrative Agent.

          This opinion is furnished to you pursuant to subsection 9(d) of the
 Amendment. Capitalized terms used herein and not otherwise defined shall have
 the meanings assigned to such terms in Appendix A to the Liquidity Agreement.
 References to Schedules, unless otherwise indicated, refer to the Schedules
 appended to this opinion letter.

          In so acting, we have examined the executed counterparts of the
 Amendment and the Liquidity Agreement and each exhibit and schedule thereto. We
 have also examined and relied upon originals or copies, certified or otherwise
 identified to our satisfaction, of such other documents, certificates,
 corporate records and other
<PAGE>
 
The Persons Listed on
 Annex I Hereto                    -2-                           August  , 1996
                                                                       
 
instruments, and have made such other and further investigations, as we have
deemed relevant and necessary as a basis for the opinions hereinafter set forth.

          As to questions of fact we have relied upon the documents we have
examined or upon certificates and statements of officers of the Foreign
Liquidity Lenders, the Domestic Liquidity Lenders and of public officials. In
our examination we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals and the conformity to
original documents of all documents submitted to us as certified copies or
photocopies and the authenticity of the originals of such latter documents.

          With your permission, based in part upon and without any independent
investigation of a certificate of each of the Domestic Liquidity Lenders and the
Foreign Liquidity Branches (a copy of each of which is attached hereto as Annex
II), we have assumed that:

          (a) each Domestic Liquidity Lender listed on Schedule A-4 and each
     Foreign Liquidity Lender has been duly organized and is validly existing
     under the laws of its jurisdiction of organization;

          (b) each Domestic Liquidity Lender listed on Schedule A-4 and each
     Foreign Liquidity Lender has all requisite power and authority under the
     laws of its jurisdiction of organization to execute, deliver and perform
     the Liquidity Agreement;

          (c) each Domestic Liquidity Lender listed on Schedule A-4 and each
     Foreign Liquidity Branch listed on Schedule A-7 is licensed by the
     superintendent of banks (or other similar government official) of the state
     in which such Domestic Liquidity Lender or such Foreign Liquidity Branch is
     located and each such Domestic Liquidity Lender and each such Foreign
     Liquidity Branch is qualified to do business as a banking corporation or as
     a state branch of the related Foreign Liquidity Lender, respectively, in
     accordance with the provisions of the banking law of such state;

          (d) the Amendment has been duly authorized, executed and delivered by
     each of the parties thereto, including the Foreign Liquidity Lenders acting
     through their respective Foreign Liquidity Branches and the Domestic
     Liquidity Lenders, and no further corporate action on the part of the
     Foreign Liquidity Lenders acting through their respective Foreign Liquidity
     Branches

     or on the part of the Domestic Liquidity Lenders, as the case may be, is
     required in connection with the execution, delivery and performance of the
     Amendment or the Liquidity Agreement;

          (e) the execution, delivery and performance of the Amendment and the
     Liquidity Agreement by each Foreign Liquidity Branch and Domestic Liquidity
     Lender do not and will not violate the organizational documents of the
     related Foreign Liquidity Lender or such Domestic Liquidity Lender, as the
     case may be, or any contract or undertaking to which such Foreign Liquidity
     Branch or the related Foreign Liquidity Lender or such Domestic Liquidity
     Lender, as the case may be, is a party or to which it is bound or the legal
     lending limit applicable to such Foreign Liquidity Branch or such Domestic
     Liquidity Lender, as the case may be, or any provision of the laws of (i)
     the state, if other than New York, wherein the principal banking office of
     such Domestic Liquidity Lender is located and (ii) the jurisdiction of
     organization of such Foreign Liquidity Lender; and

          (f) the obligation of each Foreign Liquidity Branch and of each
     Domestic Liquidity Lender listed on Schedule A-4 to make Refunding Loans
     under the Liquidity Agreement constitutes the valid and legally binding
     obligations of such Foreign Liquidity Branch and the related Foreign
     Liquidity Lender and of such Domestic Liquidity Lender, as the case may be,
     under the laws of (i) the state, if other than New York, wherein the
     principal banking office of such Domestic Liquidity Lender is located and
     (ii) the jurisdiction of organization of such Foreign Liquidity Lender.

          Based upon the foregoing and subject to the limitations and
 qualifications herein set forth, we hereby advise you that in our opinion:

          1. Each Domestic Liquidity Lender listed on Schedule A-2 is a national
     banking association organized under the laws of the United States.

          2. Each Domestic Liquidity Lender listed on Schedule A-3 is licensed
     by the Superintendent of Banks of the State of New York and qualified to do
     business as a New York banking corporation in accordance with the
     provisions of the Banking Law of the State of New York.

          3. Each Foreign Liquidity Lender having a Foreign Liquidity Branch
     listed on Schedule A-5 has been authorized by the Comptroller of the
<PAGE>
 
The Person Listed on
 Annex I Hereto                      -4-                       August   , 1996

 
     Currency to establish and operate such Foreign Liquidity Branch in
     conformity with the laws of the United States.

          4. Each Foreign Liquidity Branch listed on Schedule A-6 is licensed by
     the Superintendent of Banks of the State of New York and qualified to do
     business as a New York branch of the related Foreign Liquidity Lender in
     accordance with the provisions of Article V of the Banking Law of the State
     of New York.

          5. Each Domestic Liquidity Lender listed on Schedule A-2 and each
     Foreign Liquidity Branch listed on Schedule A-5 has the power and authority
     under title 12 of the United States Code to enter into the Liquidity
     Agreement and to make Refunding Loans thereunder.

          6. Each Domestic Liquidity Lender listed on Schedule A-3 and each
     Foreign Liquidity Branch listed on Schedule A-6 has the power and authority
     under the Banking Law of the State of New York to enter into the Liquidity
     Agreement and to make Refunding Loans thereunder.

          7. The Liquidity Agreement, including the obligation of each Foreign
     Liquidity Branch and Domestic Liquidity Lender to make Refunding Loans
     thereunder in accordance with the terms thereof, constitutes a valid and
     legally binding obligation of such Foreign Liquidity Branch or Domestic
     Liquidity Lender, as the case may be, severally and not jointly and only to
     the extent of such Foreign Liquidity Branch's or Domestic Liquidity
     Lender's Commitment, enforceable against such Foreign Liquidity Branch or
     Domestic Liquidity Lender in accordance with its terms, subject to the
     effects of bankruptcy, insolvency, receivership, conservatorship,
     liquidation, fraudulent conveyance, reorganization, moratorium or other
     similar laws relating to or affecting rights of creditors generally or of
     creditors of banks the accounts of which are insured by the Federal Deposit
     Insurance Corporation, general equitable principles (whether considered in
     a proceeding in equity or at law) and an implied covenant of good faith and
     fair dealing and, in the case of such Foreign Liquidity Branch or the
     related Foreign Liquidity Lender, the possible judicial application of
     foreign laws or foreign governmental action or judicial action affecting
     creditors' rights.

          Our opinion with respect to the enforceability of the obligation of
 each Foreign Liquidity Branch under the Liquidity Agreement relates only to the
 enforceability of the same against such Foreign Liquidity Branch. We express no
 opinion as to

enforceability by the Issuer of its right to receive Refunding Loans in the

The Persons Listed on
Annex I Hereto

Ladies and Gentlemen:

          We have acted as special [name of state] counsel to [name of Lender]
(the "Lender") in connection with the execution and delivery by [the Lender] [,
acting through its [name of state] branch of the Lender (the "Branch"),] of the
Second Amendment and Consent, dated as of August __, 1996 (the "Amendment"),
among Case Equipment Loan Trust 1994-B, a Delaware business trust (the
"Issuer"), the Lender [acting through the Branch], the other financial
institutions parties thereto, and The Chase Manhattan Bank, as administrative
agent (the "Administrative Agent"), amending a Liquidity Agreement dated as of
June 23, 1994 (as amended, the "Liquidity Agreement") among the Issuer, the
financial institutions parties thereto and the Administrative Agent.

          This opinion is furnished to you pursuant to subsection 9(d) of the
Amendment.  Capitalized terms used herein and not otherwise defined shall have
the meanings assigned to such terms in Appendix A to the Liquidity Agreement.

          In so acting, we have examined executed counterparts (or photocopies
thereof) of the Amendment and the Liquidity Agreement and each exhibit and
schedule thereto.  We have also examined and relied upon originals or copies,
certified or otherwise identified to our satisfaction, of such other documents,
certificates, corporate records and other instruments, and have made such other
and further investigations, as we have deemed relevant and necessary as a basis
for the opinions hereinafter set forth.

          As to questions of fact we have relied upon the documents we have
examined or upon certificates and statements of officers of the Lender and of
public officials.  In our examination we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals and
the conformity to original documents of all documents submitted to us as
certified or photocopies and the authenticity of the originals of such latter
documents.

          [IF A FOREIGN BRANCH: With your permission, based in part upon and

          (c)  the Amendment has been duly authorized, executed and delivered by
     each of the parties thereto, including the Lender acting through the
     Branch, and no further corporate action on the part of the Lender acting
     through the Branch is required in connection with the execution, delivery
     and performance of the Liquidity Agreement or the Amendment;

          (d)  the execution, delivery and performance of the Liquidity
     Agreement and the Amendment by the Branch does not and will not violate the
     organizational documents of the Lender or any contract or undertaking to
     which such Branch or the Lender is a party or to which it is bound or any
     provision of the laws of the jurisdiction of organization of such Lender;
     and

          (e)  the obligation of the Branch to make Refunding Loans under the
     Liquidity Agreement constitutes the legal, valid and binding obligations of
     the Branch and the Lender under the laws of the jurisdiction of
     organization of the Lender.]

          Based upon the foregoing and subject to the limitations and
qualifications herein set forth, we hereby advise you that in our opinion:

          [IF A DOMESTIC BANK: 1.  The Lender is a banking corporation duly
     organized and validly existing in good standing under the laws of [name of
     state] and has full corporate power and authority to execute, deliver and
     perform its obligations under the Amendment and the Liquidity Agreement.

          2.  The Amendment has been duly authorized, executed and delivered by
     the Lender and no further corporate action on the part of the Lender is
     required in connection with the execution, delivery and performance of the
     Amendment or the Liquidity Agreement.

     Liquidity Agreement by the Lender do not and will not violate the charter

To the Persons Listed
 on Annex I Hereto


Ladies and Gentlemen:

          In connection with the Second Amendment and Consent, dated as of
August __, 1996 (the "Amendment"), among Case Equipment Loan Trust 1994-B, a
Delaware business trust (the "Issuer"), [name of foreign lender] (the "Lender"),
acting through its [name of state] branch (the "Branch"), the other financial
institutions parties thereto, and The Chase Manhattan Bank, as administrative
agent (the "Administrative Agent"), amending a Liquidity Agreement, dated as of
June 23, 1994 (as amended, the "Liquidity Agreement"), among the Issuer, the
financial institutions parties thereto and the Administrative Agent, the
undersigned, as counsel for the Lender, has examined such corporate records,
certificates and other documents and such questions of law as I have considered
necessary and appropriate for purposes of this opinion.  In my examination, I
have assumed the genuineness of all signatures, the authenticity of all
documents submitted to me as originals and the conformity to authentic, original
documents of all documents submitted to me as certified, conformed or
photostatic copies.  No opinion is expressed herein as to the laws of any
jurisdiction other than the laws of [country of organization].

          With your permission, based in part upon and without any independent
investigation of an opinion of Simpson Thacher & Bartlett, I have assumed for
the purpose of my opinion hereinafter expressed that the Liquidity Agreement
will constitute the legal, valid and binding obligations of the Lender in
accordance with New York law.

          Based on the foregoing, I advise you that, it is my opinion:

          1.  The Lender is a banking corporation duly organized and validly
     existing in good standing under the laws of [name of country] and has full
     corporate power and authority to execute, deliver and perform its
     obligations under the Amendment and the Liquidity Agreement.

   Annex I Hereto                      -2-                        August__, 1996


 
          2.  The Amendment and the Liquidity Agreement have been duly
     authorized by the Lender, through the Branch.

          3.  The Liquidity Agreement is enforceable in accordance with its
     terms against the Lender's head office in [name of country] if the Branch
     defaults in its obligations under such Liquidity Agreement or the Lender
     ceases to have a presence in the [name of state where Branch is located]
     except as enforceability may be limited by applicable bankruptcy,
     insolvency, reorganization, moratorium or similar laws affecting the
     enforcement of creditors' rights generally and by general equitable
     principles (whether enforcement is sought by proceedings in equity or at
     law).

          4.  The choice of the law of the State of New York to govern the
     Liquidity Agreement is valid under the laws of [name of country] and a
     court in [name of country] would uphold such choice of law in a suit or
     other proceeding on the Liquidity Agreement brought in a court of [name of
     country], provided that the application of such law to the case would not
     result in a contravention of public policy of [name of country].

          5.  Any final and conclusive judgement for a fixed and definite sum
     obtained against the Branch in any competent United States Federal or state
     court having jurisdiction over the branch in respect of any suit, action or
     proceeding against the Branch for the enforcement of the Liquidity
     Agreement will, upon request, be declared valid and enforceable against the
     Lender by the competent courts at the legal domicile of the Lender in [name
     of country] without relitigation of the matters adjudicated, provided that
     its contents are not contrary to, and the judgement has not been rendered
     in violation of, public policy of [name of country] and provided that due
     process was not denied and the same subject matter was not first brought or
     earlier adjudicated in another court.

          6.  The obligations of the Lender under the Liquidity Agreement rank
     pari passu with all deposits and other unsecured obligations of the Lender.

          7.  No license, consent or approval of, or registration with, any
     governmental department, agency, commission or regulatory authority of
     [name of country] is required in connection with the execution or
     performance of the Liquidity Agreement by the Lender, acting through the
     Branch, to make the Liquidity Agreement fully enforceable in accordance
     with its terms.

          I express no opinion as to the laws of any jurisdiction other than the
laws of the [name of country].
