Dear C.A.:

This letter amends and supersedes that letter agreement dated October 8, 1997

You will resign as President and Chief Executive Officer of Tyler as of 
December 9, 1998. You will serve as an employee director and member of the 
Executive Committee until June 30, 2000.

Primary Duties and Compensation

     1.   Primary Duties. Your primary duties will consist of serving as 
Chairman and as an employee of FCAP and will consist of the development and 
implementation of a strategy to maximize the shareholder value of Forest City 
Auto Parts ("FCAP") through the sale or liquidation of all or substantially all 
of FCAP (or such other means as the Tyler Board of Directors may pursue), upon 
terms to be approved by the Tyler Board of Directors.

     2.   Salary. In consideration for your service and efforts in the sale of 
FCAP, your total cash compensation will be $315,000, which will be payable at a
rate of $17,500 per month beginning January 1, 1999. Any remaining portion of
the $315,000 due to be paid to you for your service described above will be
paid to you in full upon the closing of a sale of all or substantially all of
FCAP. You will continue to be paid at your current rate through December 31,
1998.

     3.   Non-Accountable Expense Allowance. In addition to the salary 
described above, you will be entitled to a non-accountable expense allowance of
$36,000, which will be payable at a rate of $2,000 per month. Any remaining
portion of the $36,000 due to be paid to you for your service described above
will be paid to you in full upon the closing of a sale of all or substantially
all of FCAP.

     4.   Stock Grant. As additional compensation for your service and efforts 
in the sale of FCAP, the unvested 75,000 shares of restricted Tyler common
stock originally granted to you under the October 8, 1997 letter agreement will
vest on the following schedule:


                                           
                       April 8, 1999          25,000
                       October 8, 1999        25,000
                       April 8, 2000          25,000



except that all of such shares will vest immediately upon the closing of a sale 
of all or substantially all of FCAP.

     5.   Office Location and Support. To assist you in your efforts to 
maximize shareholder value of FCAP, you will use such assistants and support as 
mutually agreed. You and your assistants will work out of the office located at 
2121 San Jacinto Street, Suite 2900, Dallas, Texas 75201. Tyler will continue 
to pay your office assistant, Pat Dugan, at her current rate through December

     1.   Additional Tyler Duties. In addition to your primary duties as 
Chairman and an employee of FCAP, you will be available at Tyler's request on 
a mutually satisfactory schedule for up to forty (40) hours per month until 
January 1, 2002 at no additional compensation while being compensated by FCAP. 
Any time requested by Tyler resulting in hours worked in excess of forty (40) 
hours per month shall be paid at a rate of $200 per hour. Any such service will 
be performed at 2800 W. Mockingbird Lane, Dallas, Texas 75235 or at such other 
location as mutually agreed.

     2.   Additional Compensation. Should your salary be prepaid as described 
upon the sale of FCAP, you will remain an employee of Tyler at a salary equal 
to $1,250 per month until January 1, 2002.
