Ms. Sue Main

Westlake Village, CA 91362

Dear Sue:

Confirming our discussions, I am very pleased to receive your acceptance of our
offer to become Teledyne's Vice President and Controller effective March 29,
2004. This position will report directly to me.

The key aspects of your employment would be as follows:

1.    Base salary of $225,000 to be reviewed on the same basis as others in
      similar positions. Your next annual review will be in September 2005.

2.    An annual target bonus opportunity of 45% of base salary with a maximum of
      90% of base salary at 120% of performance, on the terms and conditions
      established by the Personnel and Compensation Committee of the Company.

3.    You will be eligible for an annual grant of options to purchase 10,000
      shares of common stock beginning in early 2005. All terms and conditions
      of any stock option program are established and approved by the Personnel
      and Compensation Committee of the Board of the company and, as such, are
      subject to change.

4.    You will be eligible to participate in the Company's Performance Share
      Plan (PSP). The plan is designed to reward participating executives for
      achieving pre-specified goals measured over a three-year period. Your
      target opportunity as a percent of base salary is 100%. Awards will be
      made one-half in stock and one-half in cash with payments made over a
      three-year period following the three-year performance period. Your
      participation will be prorated. All terms and conditions of the
      Performance Share Program are established and approved by the Personnel
      and Compensation Committee of the Board of the company and, as such, are
      subject to change.





5.    You will be eligible to participate in the Company's Restricted Stock
      Program (RSP). The plan is intended to be restricted to the top executives
      whose actions most directly affect the long-term success of the company.
      Pre-specified performance targets measured over three years must be met at
      threshold or better in order to release the restrictions. Restricted stock
      equal in value to 30% of your base salary are granted, generally each
      calendar year. Your participation will be prorated. All terms and
      conditions of the Restricted Stock Program are established and approved by
      the Personnel and Compensation Committee of the Board of the company and,
      as such, are subject to change.

6.    You will receive a Change in Control Severance Agreement at two times your
      base salary.

7.    You will receive three weeks of vacation.

8.    You will be eligible for a Company automobile at the Vice
      President/General Manager level (2004 = $31,000).

In addition, our arrangement will also be subject to your successful completion
of a standard pre-employment physical examination and drug and alcohol screen.

Please be advised that your employment with the company will be at-will, and
that it may be terminated by you or by the company at any time and for any
reason, with or without cause, and with or without notice. By accepting this
offer, you represent and agree that no contrary representation has been made to
you. This at-will employment relationship will remain in effect throughout your
employment with the company and its affiliated entities, and may only be
modified by an express written contract for a specified term signed by you and
the Senior Vice President, General Counsel and Secretary of the Company. It may
not be modified by an oral or implied agreement. This letter sets forth the
parties' entire agreement regarding the subjects addressed.

Sue, I am confident you will make a significant contribution to Teledyne
Technologies. Please sign, date and return one of the original offer letters to
acknowledge the terms outlined in this letter.

Sincerely

/s/ Dale A. Schnittjer
