Teledyne Technologies Incorporated 401(k) Plan
Audited Financial Statements and Supplemental Schedules
For the Year Ended December 31, 2002

Report of Independent Auditors

Teledyne Technologies Incorporated
As Plan Administration of the Teledyne Technologies Incorporated 401(k) Plan

We have audited the accompanying statements of net assets available for benefits of Teledyne Technologies Incorporated 401(k) Plan as of December 31, 2002 and 2001, and the related statement of changes in net assets available for benefits for the year ended December 31, 2002. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2002 and 2001, and the changes in its net assets available for benefits for the year ended December 31, 2002, in conformity with accounting principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedules of assets (held at end of year) as of December 31, 2002, and nonexempt transactions for the year then ended, are presented for purposes of additional analysis and are not a required part of the financial statements but are supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan’s management. The supplemental schedules have been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, are fairly stated in all material respects in relation to the financial statements taken as a whole.

Teledyne Technologies Incorporated 401(k) Plan

Notes to Financial Statements

December 31, 2002

1.     Description of the Plan

General

The Teledyne Technologies Incorporated 401(k) Plan, as amended, (the Plan) is a defined contribution plan available to eligible U.S. domestic employees of Teledyne Technologies Incorporated (Teledyne or the Company). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The Plan was amended in October 2001 and 2002 to reflect certain provisions of the Economic Growth and Tax Relief Reconciliation Act of 2001. The latter amendment revised the definition of “Disability” and the final Minimum Required Distribution Regulation issued by the Internal Revenue Service. In December 2002, the Plan was also amended to reflect changes to accommodate the acquisition of Monitor Labs Incorporated. For a more complete description of the Plan’s provisions please refer to the Plan document.

Contributions

Participants can defer between 1% and 15%, subject to Internal Revenue Code limitations, of their eligible wages and contribute them to the Plan. Employees generally become eligible for Company matching contributions following 90 days of service. Qualifying employee contributions are partially matched by the Company up to a maximum of $1,000 annually for each participant.

Participant Accounts

Separate accounts are maintained by the recordkeeper for each participating employee. Asset management fees charged for the administration of all funds are charged against net assets available for benefits of the respective fund. Certain other expenses of administering the Plan are paid by the plan sponsor.

Vesting

Participants are 100% vested in their contributions, Company matching contributions and all earnings thereon.

1.     Description of the Plan (continued)

Participant Loans

Active employees can borrow up to 50% of their vested account balances. The loan amounts are further limited to a minimum of $500 and a maximum of $50,000, and an employee can have no more than one loan outstanding at any given time. Interest rates are determined based on commercially accepted criteria, and payment schedules vary based on the type of loan. Loans may be paid in full or in part at any time. Loans are repayable over periods of up to five years (15 years for loans to purchase the participant’s primary residence). Payments are generally made through payroll deductions.

Plan Termination

In the event that the Plan is terminated, or the plan sponsor permanently discontinues making contributions, all amounts credited to the accounts of affected participants will be distributed to participants as defined in the Plan document.

Withdrawals and Distributions

The Plan allows for participants to make withdrawals from the Plan upon reaching age 59 1/2. Additionally, the value of participant’s contributions and the value of all Company matching contributions are payable to participants upon death, disability, retirement or upon termination of employment with the Company. At the participant’s election, payment may be made in cash as a single lump sum or in installments.

Administrative Expenses

The Company pays administrative expenses, which include recordkeeping and trustee fees as well as expenses incurred in administering the Plan. Participants pay loan origination and servicing fees.

Notes to Financial Statements (continued)

2.     Significant Accounting Policies (continued)

Basis of Accounting

The accompanying financial statements of the Plan have been prepared on an accrual basis.

Valuation of Investments

Mutual funds and common collective trust funds are stated at their unit values established for each fund by the fund manager, at each valuation date, which fluctuate with the value of the assets in each fund. Units of the Teledyne Technologies Incorporated Stock Fund and assets of the Fidelity Brokerage Link Account are valued principally on the basis of the quoted market value. Participant loans are stated at their outstanding balance which approximates fair value.

Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates.

3.     Investments

Plan participants can invest their contributions and any Company matching contributions in any or all of the investment programs managed by the Plan’s trustee. The Plan’s investments are held by Fidelity Management Trust Company (Fidelity), the trustee. One of the investment options offered through Fidelity is the Fidelity Brokerage Link Account, which enables a participant to invest in individual common stocks, preferred stocks mutual funds corporate bonds, Fidelity funds, and short term investments as stipulated in the Plan document.

4.     Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated December 23, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the “Code”) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The plan sponsor has indicated that it will take the necessary steps, if any, to maintain the Plan’s qualified status.

5.     Parties-in-Interest

During 2002 and 2001, the Plan invested in mutual funds managed by Fidelity. Trustee and investment fees paid during 2002 were based on customary and reasonable rates for such services.
