Mr. Jean-Pierre Rosso
Case Corporation
700 State Street
Racine, WI 53404

Dear Jean-Pierre:

The purpose of this letter (the "Letter Agreement") is to restate the terms and 
conditions by which you are and have been employed as President, Chief Executive
Officer and, in addition, effective March 15, 1996, Chairman of Case Corporation
(the "Company"). Certain items of compensation, that you have already received,
are set forth in Exhibit A, which is expressly incorporated herein. You hereby
acknowledge that you have received those items set forth in Exhibit A and that
the Company and Tenneco Inc. ("Tenneco") have performed all of the obligations
imposed upon them by the agreements referenced in Section 12 hereof, except for
items which by their terms have not become due either through the passage of
time or the occurrence of specified events.

1.    Your employment commenced on April 1, 1994.  You are reporting to the 
      Board of Directors.

2.    Your base salary will be at least $600,000 a year through December 31,
      1995, $700,000 per year effective January 1, 1996 and, effective January
      1, 1997, your base salary will be increased to $800,000 per year, which
      shall be subject to such increase as may from time to time be approved by
      the Compensation Committee of the Company's Board of Directors (which
      increased salary shall not thereafter be decreased).

3.    Beginning in 1995, the annual target value of your long-term stock awards,
      whether in the form of restricted stock, stock options, other forms of
      stock-based grants or a combination thereof, in the aggregate for each
      year, shall be not less than $1,000,000.

4.    Effective for bonuses which relate to 1996 and later years, the annual
      target of your bonus will be no less than $400,000. Effective January 1,
      1996, your bonus target will be no less than your base salary.

5.    You will receive non-cash compensation (e.g., Company car) and
      qualified/welfare benefits provided to the Company's senior executives.
      The Company will also reimburse you for the costs of financial and estate
      planning up to $20,000 per year.

6.    You will have four weeks vacation per year. If you choose to spend your
      vacation in your home country, the Company will pay round trip air travel
      for you and your family once a year. The Company's normal policy regarding
      accrued but unused vacation time will apply to you.

7.    You will receive a pension benefit from the Company and its pension plans
      which, in the aggregate, will not be less than the amount which you would
      have been entitled to receive if your coverage under the Honeywell, Inc.,
      defined benefit plans in effect at March 18, 1994 had continued until your
      separation of service from the Company, less any benefits from such
      Honeywell, Inc. plans. If, within four years of the date specified in
      Section 1 hereof, the Company terminates your employment other than for
      death, disability or the gross neglect of your duties or if you
      voluntarily terminate your employment with the Company and are entitled to
      severance benefits under Section 8 below, you will, nevertheless be
      treated as having received four years credit for service with the Company.
      The benefits guaranteed hereunder includes an age 57 subsidized early
      retirement benefit.

8.    If your employment with the Company is terminated within four years of the
      date specified in Section 1 hereof, other than for death, disability, or
      the gross neglect of your duties, the Company will pay you a severance
      benefit in an amount equal to three times your base salary then in effect.
      If your employment is terminated thereafter other than for death,
      disability, or the gross neglect of your duties, the Company will pay you
      a severance benefit in an amount equal to two times your base salary then
      in effect. If you resign voluntarily or retire, you will not be entitled
      to this severance benefit.

      In addition, notwithstanding the foregoing, you may elect to voluntarily
      terminate your employment with the Company and still be entitled to
      receive the above indicated severance benefit if: (a) there is a material
      reduction or material adverse alteration in the nature of your position,
      responsibilities or authorities (including the failure to elect and
      continue to elect you to the Board of the Company); (b) there is a
      material reduction of your compensation or benefits hereunder; (c) you
      become the holder of a lesser office or title than Chairman, President and
      Chief Executive Officer of the Company; or (d) your job is relocated to a
      Letter Agreement; provided that if the event is not due to intentional or
      repeated action, you will provide the company with written notice of the
      event and the opportunity to cure the event within 15 days from the date
      of the notice. If the written notice is not required, you will have 30
      days from the date of the event to elect to voluntarily terminate your
      employment with the Company and still be entitled to receive the above
      indicated severance. If you give the required notice and the Company fails
      to cure the event within the 15 day period, you

Mr. Jean-Pierre Rosso

March 20, 1997



      may elect within 30 days after such period to voluntarily terminate your
      employment with the Company and still be entitled to receive the above
      indicated severance.

      For purposes of this Letter Agreement, errors in your judgment or any act
      or omission believed by you in good faith to have been in or not opposed
      to the interests of the Company will not be considered "gross neglect of
      your duties."

      You will not receive the severance benefits described in this Section 8 if
      you receive severance benefits under the Agreement Regarding Change in
      Control between yourself and the Company dated April 8, 1996.

9.    The Company will reimburse you for the tuition and fees for secondary 
      private school for your eligible children.

10.   If you are entitled to receive severance under Section 8 above, (a) the
      Company will continue to provide you with all the same benefits as in
      effect immediately prior to your termination for a period of two years
      following your termination (if your severance equals two times your base
      salary) or three years following your termination (if your severance
      equals three times your base salary), and (b) all of your Tenneco stock
      options will vest on the date of your termination and will remain
      exercisable for a period of not less than 90 days from such termination;
      all of your Company stock options will vest on the date of your
      termination and will remain exercisable for a period of not less than 12
      months from such termination, and (c) the Company will make a payment to
      you in cash in an amount equal to the value of all of your Tenneco
      restricted stock, Company restricted stock and Company convertible second
      preferred stock, which you forfeit. In addition, the minimum pension under
      Section 7 above, will be determined by treating the severance benefit as
      compensation and service to the same extent as if you remained employed by
      the Company and earned the amount of severance ratably over the two or
      three year period, as applicable, in addition to the four years specified
      in Section 7 above. If, under the terms of the Company's stock option
      plans, any stock options which have been granted to you are forfeited on
      the date of your termination, notwithstanding the foregoing provisions of
      this Section 10, the Company shall make a payment to you with respect to
      such options in an amount equal to the amount by which the fair market
      value of the Company stock on the date of such forfeiture exceed the
      option exercise price of such forfeited options. For all purposes hereof,
      the value of the Company's convertible second preferred stock shall be
      equal to the greater of (a) the number of shares of common stock of the
      Company into which such convertible second preferred shares could have
      been converted, multiplied by the closing price of a share of Company
      common stock on the date of your termination of employment plus the
      discounted present value (using First National Bank of Chicago prime or
      reference rate in effect on the date of your termination of employment) of
      the dividends payable with respect to such convertible second preferred
      shares from the date of termination through July 1, 2000 or if higher (b)
      the liquidation preference

      that would have been payable with respect to such forfeited convertible
      second preferred shares, including any accrued and unpaid dividends
      thereon.

11.   If you incur legal or other fees and expenses in an effort to establish
      entitlement to benefits under this Letter Agreement, the Company will
      reimburse you for such fees and expenses unless a court determines that
      such effort was conducted in bad faith. The Company will reimburse you on
      a monthly basis upon your written request for reimbursement together with
      proof that the fees and expenses were incurred.

12.   This Letter Agreement supersedes any and all prior agreements, whether
      oral or written, regarding your employment by the Company. Without
      limiting the generality of the foregoing, this Letter Agreement supersedes
      the letter agreements dated June 13, 1996 and May 4, 1995 between you and
      the Company, the two letter agreements dated March 18, 1994 between you
      and Case Equipment Corporation and you and Tenneco, Inc. and Barry
      Schuman's June 3, 1994 memorandum to you, but this is without prejudice to
      amounts or awards already paid or awarded to you.

13.   None of the awards specified hereunder will prejudice your eligibility for
      additional awards.

14.   The Company will provide you with a membership in a country club of your
      choice.

15.   The provisions of this Letter Agreement shall apply notwithstanding any
      inconsistent provisions contained in any current or future plan or
      agreement of the Company or Tenneco. The Company and Tenneco agree to
      amend all current and future plans and agreements to be consistent with
      the provisions herein. Any failure of the Company or Tenneco to conform
      any present or future plan or agreement to the provisions of this Letter
      Agreement shall not be deemed to waive the provisions of this Letter
      Agreement unless there is an agreement in writing between the Company,
      Tenneco and you which expressly provides that it is the parties intent to
      waive or modify such provisions of the Letter Agreement.

16.   If you forfeit any Tenneco stock options, the Company shall pay you an
      amount of cash with respect to each such option equal to the amount by
      which the market value of Tenneco shares subject to such options exceeds
      the option exercise price on the date of your election to receive such
      benefits (determined under the terms and conditions of the Tenneco stock
      option plans and agreements, as though your employment with the Company
      were employment with Tenneco and the your right to elect this payment was
      a right to elect to exercise such forfeited Tenneco stock option). If you
      should forfeit any Tenneco restricted stock, the Company shall make a
      payment to you in cash in an amount equal to the value of all of your
      Tenneco restricted stock so forfeited at the date you would have become
      vested in such Tenneco restricted stock had your employment with the
      Company been treated for all purposes under the Tenneco restricted stock
      grant to be employment with Tenneco.

                                   EXHIBIT A

1.    You have become a participant in the Case Non-Qualified Deferred
      Compensation Plan ("DCP"). You have been credited with $25,000, as a
      discretionary Company credit with respect to 1994. This credit is in lieu
      of any credit previously awarded under the Tenneco Deferred Compensation
      Plan.

2.    You were previously awarded 20,000 restricted shares of Tenneco Inc.
      Common Stock under the 1994 Tenneco Inc. Stock Ownership Plan (the
      "Tenneco Stock Plan") which are subject to the Restricted Stock Award
      Agreement attached hereto as Exhibit A-1. You were previously awarded a
      non-qualified stock option under the Tenneco Stock Plan to purchase 20,000
      shares of Tenneco Common Stock, which are subject to the Non-Qualified
      Stock Options Award Agreement attached hereto as Exhibit A-2, except to
      the extent that Section 10 of the Letter Agreement may provide you with
      greater rights with respect thereto.

3.    On June 23, 1994, you were issued 20,500 shares of the Company's
      convertible second preferred stock. On August 17, 1994, you were granted
      a non-qualified option to purchase 200,000 shares of Company Common Stock
      under the Case Equity Incentive Plan (the "CEIP"). On December 7, 1994,
      you were granted a non-qualified stock option to purchase an additional
      200,000 shares of Company Common Stock under the CEIP. These grants are
      subject to the Non-Qualified Stock Options Award Agreements, as amended
      and restated in the form attached hereto as Exhibits A-3 and A-4,
      respectively, (which agreements are in substitution of the prior
      agreements executed with respect to the August 17, 1994 and December 7,
      1994 non-qualified stock option grants) except to the extent that Section
      10 of the Letter Agreement may provide you with greater rights with
      respect thereto.

4.    In December 1995, the Company paid you a bonus of $699,900, consisting of
      a $300,000 cash payment and shares of stock (net of shares withheld to
      satisfy tax withholding) with a value of $399,900. In January 1997, the
      Company paid you a bonus of $1,283,333, consisting of a $550,000 cash
      payment and shares of stock (net of shares withheld to satisfy tax
      withholding) with a value of $733,333.

5.    On each of December 7, 1995 and December 11, 1996, you were granted a
      non-qualified option to purchase 75,000 shares of Company Common Stock
      under the CEIP. On December 7, 1995 and December 11, 1996, you were
      awarded 20,000 and 25,000 shares, respectively, of restricted Common Stock
      under the CEIP.
