Dear Xxxx:

     The Board of Directors has carefully reviewed your Employment Agreement,
dated as of December 1, 1996 and amended and restated as of September 29, 1999.
In connection with your separation from Federal-Mogul Corporation ("F-M") on
September 19, 2000 (the "Separation Date"), the Board is prepared to offer the
following separation benefits in accordance with the terms of your Employment
Agreement:

     1.  Severance Compensation.  F-M will pay you the following severance
         ----------------------
compensation, less applicable tax withholdings and other normal payroll
deductions in accordance with F-M's payroll practices:

     a.  $2,000,000, which is equivalent to two times your base salary as of the
         Separation Date. This amount will be reduced by any compensation you
         receive between the Separation Date and the date on which F-M receives
         your executed Separation and General Release Agreement.

     b.  $1,900,244, which is equivalent to two times the average of the bonus
         compensation you received over the three-year period 1997 through 1999.

     c.  $209,030 as payment in full of your EVA bonus bank.

     d.  $76,923, which is equivalent to four weeks' vacation pay.

     2.  Supplemental Key Executive Pension Plan (SKEPP).  You will receive an
         -----------------------------------------------
estimated net pay replacement of 26.3%, which equals approximately $483,000 per
year calculated on a single life annuity basis.  In accordance with the terms of
the SKEPP, this amount will be offset by (i) the amount you are entitled to
receive under the F-M Personal Retirement Account, calculated on a single life
annuity basis; (ii) the pension benefit you are entitled to receive from
Tenneco, calculated on a single life annuity basis; and (iii) all applicable
taxes.  The exact amount of your SKEPP payment will be subject to final
confirmation by the Plan actuary (Mercer).

         -------------------------
         participation in F-M's CHOICE Benefit Plan to the extent of and in
         accordance with your 2000 CHOICE plan coverage elections. Any changes
         F-M makes to its CHOICE Benefit Plan during the two years following the
         Separation Date will similarly affect your CHOICE Benefits.

     b.  Tax Preparation and Financial Planning.  For two years following the
         --------------------------------------
         Separation Date, you will be entitled to financial planning services
         and tax planning services in accordance with F-M's policies regarding

         -------------
         performance based and 150,000 time based non-qualified stock options
         issued on November 1, 1996, with an exercise price of $22.625. You are
         fully vested in the performance based options, and based on your length
         of employment, you have vested in 3/5th or 90,000 of the time based
         options. An additional 30,000 time based options would have vested on

         vesting in the remaining 60,000 time based options, your term of
         employment shall be deemed to continue until September 19, 2002. In the

         immediately vested in all of the time based options. All 300,000
         options granted on November 1, 1996 will be exercisable by you, to the
         extent vested, until November 1, 2004, on which date they will expire,
         notwithstanding any contrary terms in the 1989 Performance Incentive
         Stock Plan or otherwise.
