                                     FORM OF
                        RESTRICTED STOCK AWARD AGREEMENT

                                  July 25, 2000

            The parties to this Restricted Stock Award Agreement (this
"Agreement") are Teledyne Technologies Incorporated, a Delaware corporation (the
"Company"), and _____________ (the "Executive").

                                   WITNESSETH:

            WHEREAS, the Company has adopted the Teledyne Technologies
Incorporated Restricted Stock Award Program (the "Program") for the benefit of
eligible employees of the Company and its subsidiaries;

            WHEREAS, the terms and conditions of the Program are set forth in
administrative rules (the "Rules") adopted by the Personnel and Compensation
Committee of the Board of Directors of the Company pursuant to the authority
reserved in Section 3.01 of the Teledyne Technologies Incorporated 1999
Incentive Plan, as amended (the "Plan");

            WHEREAS, the Executive has been designated as a participant under
the Program who is eligible to receive a restricted stock grant in the year
2000; and

            WHEREAS, to provide an incentive to the Executive to focus on
long-term Company performance, the Company desires to grant shares of the
Company's Common Stock to the Executive subject to certain transfer and
forfeiture restrictions set forth in this Agreement, as well as the provisions
of the Program, which shall lapse upon the third anniversary of the date of this
Agreement (the "Date of Grant") and the attainment of certain Performance Goals
(as defined in Paragraph 1.8(b)) for the Performance Cycle (as defined in
Paragraph 1.8(a));

            NOW, THEREFORE, the parties, intending to be legally bound, agree as
follows:

1.    RESTRICTED SHARES

      1.1   GRANT OF RESTRICTED SHARES.

            (a) As of the Date of Grant, the Company grants to the Executive
2,980 shares of Common Stock (the "Restricted Shares"), subject to the
restrictions set forth in Paragraph 1.2 of this Agreement, the terms and
conditions of the Program and the other terms and conditions contained in this
Agreement. If and when the restrictions set forth in Paragraph 1.2 expire in
accordance with the terms of this Agreement without forfeiture of the Restricted
Shares, and
<PAGE>

upon the satisfaction of all other applicable conditions as to the Restricted
Shares, such shares shall no longer be considered Restricted Shares for purposes
of this Agreement.

            (b) As soon as practicable after the Date of Grant, the Company
shall direct that a stock certificate or certificates representing the
applicable Restricted Shares be registered in the name of and issued to the
Executive. Such certificate or certificates shall be held in the custody of the
Company or its designee until the expiration of the applicable Restricted Period
(as defined in Paragraph 1.3). On or before the date of execution of this
Agreement, the Executive has delivered to the Company one or more stock powers
endorsed in blank relating to the Restricted Shares.

            (c) Each certificate for the Restricted Shares shall bear the
following legend (the "Program Legend"):

            The ownership and transferability of this certificate and the shares
            of stock represented hereby are subject to the terms and conditions
            (including forfeiture) of the Restricted Stock Award Program under
            the Teledyne Technologies Incorporated 1999 Incentive Plan, as
            amended, and a Restricted Stock Award Agreement entered into between
            the registered owner and Teledyne Technologies Incorporated. Copies
            of such Program and Agreement are on file in the offices of Teledyne
            Technologies Incorporated, 2049 Century Park East, Suite 1500, Los
            Angeles, California 90067.

In addition, the stock certificate or certificates for the Restricted Shares
shall be subject to such stop-transfer orders and other restrictions as the
Company may deem advisable under the rules, regulations, and other requirements
of the Securities and Exchange Commission, any stock exchange upon which the
Common Stock is then listed, and any applicable federal or state securities law,
and the Company may cause a legend or legends to be placed on such certificate
or certificates to make appropriate reference to such restrictions.

            (d) As soon as administratively practicable following the expiration
of the Restricted Period without a forfeiture of the Restricted Shares, and upon
the satisfaction of all other applicable conditions as to the Restricted Shares,
including, but not limited to, the payment by the Executive of all applicable
withholding taxes, the Company shall deliver or cause to be delivered to the
Executive a certificate or certificates for the applicable Restricted Shares
which shall not bear the Program Legend.

      1.2   RESTRICTIONS.

            (a) The Executive shall have all rights and privileges of a
stockholder as to the Restricted Shares, including the right to vote and receive
any dividends or other distributions with respect to the Restricted Shares,
except that the following restrictions shall apply:

                                      -2-
<PAGE>

                  (i) the Executive shall not be entitled to delivery of the
            certificate or certificates for the Restricted Shares until the
            expiration of the Restricted Period without a forfeiture of the
            Restricted Shares and upon the satisfaction of all other applicable
            conditions;

                  (ii) none of the Restricted Shares may be sold, transferred,
            assigned, pledged or otherwise encumbered or disposed of during the
            Restricted Period (other than by will or the laws of descent and
            distribution), except pursuant to rules adopted by the Committee in
            accordance with the Program;

                  (iii) all shares of Common Stock distributed as a dividend or
            distribution, if any, with respect to the Restricted Shares prior to
            the expiration of the Restricted Period shall be delivered to and
            held by the Company and subject to the same restrictions as the
            Restricted Shares until the termination of the Restricted Period;
            and

                  (iv) all of the Restricted Shares shall be forfeited and
            returned to the Company and all rights of the Executive with respect
            to the Restricted Shares shall terminate in their entirety on the
            terms and conditions set forth in Paragraph 1.4.

            (b) Any attempt to dispose of Restricted Shares or any interest in
the Restricted Shares in a manner contrary to the restrictions set forth in this
Agreement shall be null, void and ineffective.

      1.3 RESTRICTED PERIOD AND LAPSE OF RESTRICTIONS. Subject to the provisions
contained in Paragraphs 1.4, 1.6 and 1.7, the restrictions set forth in
Paragraph 1.2 shall apply for a period (the "Restricted Period") beginning on
the Date of Grant and ending on the third anniversary of the Date of Grant;
provided, however, that, subject to the Committee's discretion under Paragraph
1.7, in no event shall the Restricted Period expire prior to the date that the
Committee makes its determinations with respect to the Company's attainment of
the applicable Performance Goals as described in Paragraph 1.4(a).

      1.4   FORFEITURE.

            (a) If, during the Restricted Period, the Restricted Shares have not
been forfeited under Paragraph 1.4(b) as of the end of the Performance Cycle (as
defined in Paragraph 1.8(a)), all of the Restricted Shares shall be forfeited if
the Committee determines that the Company's aggregate operating profit for the
Performance Cycle is less than 75% of the target amount established under the
Company's PSP (as defined in Paragraph 1.8(c)). Further, if the Committee
determines that the Company's aggregate operating profit for the Performance
Cycle is at least 75% of the target amount, a portion of the Restricted Shares
(up to 100%) shall be forfeited if the Committee determines that the Company's
overall percentage attainment of the Performance Goals (as defined in Paragraph
1.8(b)) for the Performance Cycle is less than 100%. In that event, a portion of
the Restricted Shares shall be forfeited that is equal to (i) the aggregate

                                      -3-
<PAGE>

number of Restricted Shares reduced by (ii) the aggregate number of Restricted
Shares multiplied by the Company's percentage attainment (but not more than
100%) of the Performance Goals for the Performance Cycle, as determined by the
Committee (any fractional share resulting from this calculation shall be rounded
up to the next whole share). Except as provided in Paragraph 1.4(c), any
Restricted Shares which are not forfeited under this Paragraph 1.4(a) shall
continue to be subject to the restrictions set forth in Paragraph 1.2 for the
remainder of the Restricted Period.

            (b) Subject to Section 6.02(e) of the Rules, if during the
applicable Restricted Period (i) the Executive's employment with the Company and
its subsidiaries terminates for any reason except as otherwise provided in
Paragraph 1.4(c), (ii) there occurs a material breach of this Agreement by the
Executive or (iii) the Executive fails to meet the tax withholding obligations
described in Paragraph 1.5(b), all rights of the Executive to the Restricted
Shares shall terminate immediately and be forfeited in their entirety.

            (c) If, during the Restricted Period, the Executive's employment
terminates due to his or her death, disability (as determined in the sole
discretion of the Committee) or retirement pursuant to the retirement policy of
the Company or its applicable subsidiaries prior to the expiration of the
Performance Cycle, the Executive (or the Executive's beneficiaries) shall
continue to hold the Restricted Shares through the expiration of the Performance
Cycle. At that time, the restrictions shall lapse with respect to a portion of
the Restricted Shares equal to (i) the number of Restricted Shares that would
not be subject to forfeiture under Paragraph 1.4(a) had the Executive remained
employed by the Company through the end of the Performance Cycle multiplied by
(ii) a fraction, the numerator of which is the number of full months during
which the Executive was employed by the Company from the beginning of the
Performance Cycle until the date of the Executive's termination of employment
and the denominator of which is the total number of months in the Performance
Cycle (any fractional share resulting from this calculation shall be rounded up
to the next whole share). Any remaining Restricted Shares shall be forfeited as
of the end of the Performance Cycle. If all of the Restricted Shares would have
been forfeited under Paragraph 1.4(a), then all of the Restricted Shares shall
be forfeited under this Paragraph 1.4(c) as of the end of the Performance Cycle.

            (d) In the event of any forfeiture under this Paragraph 1.4, the
certificate or certificates representing the forfeited Restricted Shares shall
be canceled to the extent of any Restricted Shares that were forfeited.

      1.5   WITHHOLDING.

            (a) The Committee shall determine the amount of any withholding or
other tax required by law to be withheld or paid by the Company with respect to
any income recognized by the Executive with respect to the Restricted Shares.

            (b) If the Executive timely files an election under Section 83(b) of
the Internal Revenue Code and in accordance with Treasury Regulation Section
1.83-2 with respect to the Restricted Shares, the Executive shall meet the
applicable tax withholding obligation by paying the appropriate amount in cash
to the Company. If the Executive fails to meet this tax

                                      -4-
<PAGE>

withholding obligation to the satisfaction of the Company on or before the date
the Executive files his or her election under Section 83(b), all rights of the
Executive to the Restricted Shares shall forthwith terminate and be forfeited in
their entirety.

            (c) If the Executive does not file an election under Section 83(b)
of the Internal Revenue Code with respect to the Restricted Shares, the
Executive shall meet the applicable tax withholding obligation by paying the
appropriate amount in cash to the Company or, with the approval of the
Committee, by either (i) having the Company retain a number of Restricted Shares
having a Fair Market Value (as defined below) as of the date of such retention,
or (ii) delivering to the Company a number of previously acquired shares of
Common Stock (other than shares of Common Stock credited to the Executive's
account under a Company sponsored defined contribution plan or shares of Common
Stock subject to outstanding, but unexercised stock options) having a Fair
Market Value determined as of the business day preceding the date of delivery to
the Company, equal to the amount of such withholding obligation. If the
Executive fails to meet this tax withholding obligation to the satisfaction of
the Company on or before the date of the taxable event that gives rise to the
withholding obligation, the withholding obligation shall be met as described in
clause (i) above. For purposes of this Agreement, "Fair Market Value" means the
average of the composite high and low quoted sales prices of a share of Common
Stock, as reported on the Composite Tape for New York Stock Exchange Listed
Companies, over the twenty business days on which a sale was reported that
immediately precede the applicable date.

            (d) The Committee shall be authorized, in its sole discretion, to
establish such rules and procedures relating to the use of shares of Common
Stock to satisfy tax withholding obligations as it deems necessary or
appropriate to facilitate and promote the conformity of the Executive's
transactions under the Program with Rule 16b-3 under the Securities Exchange Act
of 1934, as amended, if such Rule is applicable to transactions by the
Executive.

      1.6 CHANGE IN CONTROL. Notwithstanding any provision of this Agreement to
the contrary, in the event of a Change in Control of the Company during the
Restricted Period, all of the Restricted Shares (not otherwise forfeited prior
to the Change in Control) shall vest and the applicable restrictions shall lapse
immediately.

      1.7 COMMITTEE'S DISCRETION. Notwithstanding any provision of this
Agreement to the contrary, the Committee shall have discretion under Section
6.02(e) of the Rules to adjust the Performance Cycle or waive the Restricted
Period or any other restrictions or conditions with respect to all or a portion
of the Restricted Shares at any time.

      1.8 DEFINED TERMS. Capitalized terms used but not defined in this
Agreement shall have the meanings set forth in the Program or the Plan, as the
case may be. For purposes of this Agreement, the capitalized terms set forth
below shall have the following meanings:

            (a) "Performance Cycle" shall specifically refer to the 2000-2002
Performance Cycle under the Company's PSP, including any adjustments to such
