                                IDEX CORPORATION
                              AMENDED AND RESTATED
                                STOCK OPTION PLAN
                              FOR OUTSIDE DIRECTORS

     IDEX Corporation, a corporation organized under the laws of the State of
Delaware (the "Company"), adopted the IDEX Corporation Stock Option Plan For
Outside Directors (the "Plan") effective April 24, 1990.  The original purposes
of the Plan were as follows:

          (1) To further the growth, development and financial success of the
     Company and its subsidiaries by providing additional incentives to Outside
     Directors (as defined below), by assisting them to become owners of capital
     stock of the Company and thus to benefit directly from its growth,
     development and financial success.

          (2) To enable the Company to obtain and retain the services of the
     type of Outside Directors considered essential to the long-range success of
     the Company by providing and offering them an opportunity to become owners
     of capital stock of the Company under options.

     Under the original terms of the Plan, no options could be granted more
than ten years after its adoption by the Board (as defined below).  As a
significant number of shares were still available for grant of options under
the Plan upon the original expiration date of the Plan, it is in the best
interest of the Company to continue the Plan and the grant of options to
Outside Directors thereunder.  Therefore, the following constitutes an
amendment, restatement, continuation and extension of the Plan beyond its
original term, effective upon approval of this IDEX Corporation Amended and
Restated Stock Option Plan for Outside Directors by the stockholders of the
Company, as provided in Section 7.3 hereof.

                                    ARTICLE I

SECTION 2.3 * CHANGES IN COMPANY'S SHARES

     In the event that the outstanding shares of Common Stock are hereafter
changed into or exchanged for a different number or kind of shares or other

shall be final and binding upon all Optionees, the Company and all other
interested persons.

          (b) Notwithstanding the provisions of Section 4.3(a), no Option shall

                                    ARTICLE V

                               EXERCISE OF OPTIONS

                                        7



<PAGE>   8


     Optionee, any exercisable portion of an Option may, prior to the time when
     such portion becomes unexercisable under the Plan or the applicable Stock
     Option Agreement, be exercised by his personal representative or by any
     person empowered to do so under the deceased Optionee's will or under the
     then applicable laws of descent and distribution.

          (b) Should the Optionee be determined under applicable law to have
     become a disabled person or the equivalent thereof, the Option may, prior
     to the time when the Option becomes unexercisable under the Plan or the
     applicable Stock Option Agreement, be exercised by the Optionee's guardian
     or by any other person empowered to do so under applicable laws of
     guardianship. For purposes of this Section 5.1(b), "disabled person" shall
     mean a person who (i) because of mental deterioration or physical
     incapacity is not fully able to manage his person or estate or (ii) is

     written notice to the Committee to transfer by gift, without the receipt of
     any consideration, to a member of the Optionee's immediate family, as
     defined in Rule 16a-1 under the Exchange Act, or to a trust for the
     exclusive benefit of, or any other entity owned solely by, such members,
     provided that an Option that has been so transferred shall continue to be
     subject to all of the terms and conditions of the Option Agreement as
     applicable to the Optionee, and the transferee shall execute any and all
     such documents requested by the Committee in connection with the transfer,
     including without limitation to evidence the transfer and to satisfy any
     requirements for an exemption for the transfer under applicable federal and
     state securities laws.

SECTION 5.2 * PARTIAL EXERCISE

     At any time and from time to time before any exercisable Option or
exercisable portion thereof becomes unexercisable under the Plan or the
applicable Stock Option Agreement, such Option or portion thereof may be
exercised in whole or in part; provided, however, that the Company shall not be
required to issue fractional shares and no Option may be exercised for less
than 1,000 shares of Common Stock unless such exercise is the full exercise of
the exercisable portion of such Option.

SECTION 5.3 * MANNER OF EXERCISE

     An exercisable Option, or any exercisable portion thereof, may be
exercised solely by delivery to the Secretary or his office of all of the
following prior to the time when such Option or such portion becomes
unexercisable under the Plan or the applicable Stock Option Agreement:

          (a) Notice in writing signed by the Optionee or other person then
     entitled to exercise such Option or portion thereof, stating that such
     Option or portion thereof is thereby exercised, such notice complying with
     all applicable rules established by the

                                        8

     Committee;

          (b) (i) Full payment (in cash or by check) for the shares with respect
          to which such Option or portion thereof is thereby exercised;

               (ii) With the consent of the Committee, shares of Common Stock
          which have been owned by the Optionee for more than six months on the
          date of delivery and duly endorsed for transfer to the Company with a
          Fair Market Value on the date of delivery equal to the aggregate
          Option price of the shares with respect to which such Option or
          portion thereof is thereby exercised;

               (iii) To the extent permitted by law (including the then
          interpretations of Rule 16b-3), a "cashless exercise procedure"
          satisfactory to the Committee which permits the Optionee to deliver an
          exercise notice to a broker-dealer, who then sells Option shares, and
          delivers the proceeds of the sale, less commission, to the Company
          which delivers such proceeds, less the exercise price and withholding
          taxes to the Optionee; or

               (iv) Any combination of the consideration provided in the
          foregoing subsections (i), (ii) or (iii);

          (c) Such representations and documents as the Committee, in its
     absolute discretion, deems necessary or advisable to effect compliance with
     all applicable provisions of the Securities Act and any other federal or
     state securities laws or regulations. The Committee may, in its absolute
     discretion, also take whatever additional actions it deems appropriate to
     effect such compliance, including without limitation placing legends on
     share certificates and issuing stop-transfer orders to transfer agents and
     registrars; and

          (d) In the event that the Option or portion thereof shall be exercised
     pursuant to Section 5.1 by any person or persons other than the Optionee,
     appropriate proof of the right of such person or persons to exercise the
     Option or portion thereof.

SECTION 5.4 * CONDITIONS TO ISSUANCE OF STOCK CERTIFICATES

     The shares of Common Stock issuable and deliverable upon the exercise of
an Option or any portion thereof may be either previously authorized but
unissued shares or issued shares which have been reacquired by the Company.
The Company shall not be required to issue or deliver any certificate or
certificates for shares of stock purchased upon the exercise of any Option or
portion thereof prior to fulfillment of all of the following conditions:

          (a) The listing of such shares on all stock exchanges on which such
     class of stock is then listed; and

          (b) The completion of any registration or other qualification of such
     shares,

                                        9

     and the obtaining of any other approval or clearance from any state or
     federal governmental agency which the Committee shall, in its absolute
     discretion, determine to be necessary or advisable; and

          (c) The payment to the Company of all amounts which it is required to
     withhold under federal, state or local law in connection with the exercise
     of the Option.

                                       10

SECTION 5.5 * RIGHTS AS STOCKHOLDERS

     The holders of Options shall not be, nor have any of the rights or
privileges of, stockholders of the Company in respect of any shares purchasable

holders.

                                   ARTICLE VI

                                 ADMINISTRATION

     It shall be the duty of the Committee to conduct the general
administration of the Plan in accordance with its provisions.  The Committee
shall have the power to interpret the Plan and the Options, to adopt such rules
for the administration, interpretation and application of the Plan as are
consistent therewith, and to interpret, amend or revoke any such rules.  No
member of the Committee shall be liable for any action or determination made in
good faith with respect to the Plan or any Option.

                                   ARTICLE VII

                                OTHER PROVISIONS

SECTION 7.1 * OPTIONS NOT TRANSFERABLE

     No Option or interest or right therein or part thereof shall be liable for
the debts, contracts or engagements of the Optionee or his successors in
interest or shall be subject to disposition by transfer, alienation,
anticipation, pledge, encumbrance, assignment or any other means, whether such
disposition be voluntary or involuntary or by operation of law by judgment,
levy, attachment, garnishment or any other legal or equitable proceedings
(including bankruptcy), and any attempted disposition thereof shall be null and
void and of no effect; provided, however, that nothing in this Section 7.1
shall prevent transfers by will, by the applicable laws of descent and
distribution, or as provided in Section 5.1(c).

SECTION 7.2 * AMENDMENT, SUSPENSION OR TERMINATION OF THE PLAN; MODIFICATION OF
OPTIONS

          (a) The Plan may be amended or otherwise modified, suspended or
     terminated at any time and from time to time by the Board; provided,
     however, the provisions of Sections 3.1 (Eligibility), 3.2 (Granting of
     Options) and 4.2 (Option Price) shall not be modified more than once every
     six months, other than to comport with the changes in the Internal Revenue
     Code, the Employee Retirement Income Security Act or the rules thereunder;
     provided, further that without approval of the Company's stockholders given
     within 12 months after the action by the Board, the Board may not, except
     as provided in Section 2.3, increase any limit imposed in Section 2.1 on
     the Options, modify the eligibility requirements of Section 3.1, increase
     the number of Options granted or accelerate the timing of those grants
     under Section 3.2, reduce the minimum Option price

     requirements of Section 4.2 or extend the limit imposed in this Section 7.2
     on the period during which Options may be granted and such action by the
     Board shall become effective only after stockholder approval is obtained;
     and provided, further, that no amendment or modification may be made if
     such amendment or modification would disqualify the Plan from satisfying
     the requirements of the Securities Act or the Exchange Act or any
     regulation or rule promulgated by the Securities and Exchange Commission
     thereunder. None of the amendment, suspension or termination of the Plan
     shall, without the consent of the holder of the Option, alter or impair any
     rights or obligations under any Option theretofore granted. No Option may
     be granted during any period of suspension of the Plan, and in no event may
     any Option be granted under the Plan after April 19, 2009.

          (b) An Option shall be subject in all events to the condition that, if
     at any time the Board shall determine, in its discretion, that the listing,
     registration or qualification of any of the Company's securities upon any
     securities exchange or under any law, regulation or other requirement of
