                              AMENDED AND RESTATED

                              EMPLOYMENT AGREEMENT

                                    BETWEEN

                                IDEX CORPORATION

                                      AND

                              AMENDED AND RESTATED
                              EMPLOYMENT AGREEMENT



     THIS AGREEMENT, made as of the 22nd day of November, 1996, is between IDEX
CORPORATION, a Delaware corporation with its executive offices at 630 Dundee
Road, Suite 400, Northbrook, Illinois 60062 ("IDEX"), and JERRY N. DERCK, an
individual residing at 408 Burdick Street, Libertyville, Illinois 60048 (the
"Executive").

     IDEX and the Executive entered into an Employment Agreement dated as of
September 27, 1994 (the "Effective Date").  The parties now wish to modify
certain provisions of the Employment Agreement and to restate the Employment
Agreement in its entirety as modified.  Therefore, IDEX and the Executive agree
as follows:

        1.   Introductory statement.  The Executive is willing to execute this
Agreement with respect to his employment upon the terms and conditions set
forth in this Agreement.

        2.     Agreement of employment.  IDEX agrees to, and hereby does,
employ the Executive, and the Executive agrees to, and hereby does accept,
employment by IDEX, or one of its subsidiaries, as the case may be (hereafter
in the aggregate, the "Corporation"), as an executive of the Corporation,
subject to the provisions of the by-laws of the Corporation in respect of the
duties and responsibilities assigned from time to time by the 


   3
                                    - 2 -

Chief Executive Officer of the Corporation and subject also at all times to the
control of the Board of Directors of the Corporation.

     The Corporation shall not require the Executive to perform services
hereunder away from the Chicago, Illinois area of such frequency and duration
as would necessitate, in the reasonable judgment of the Executive, the
Executive moving his residence from the Chicago, Illinois area.  Following an
Acquisition (as hereinafter defined), the Corporation shall not, in the
reasonable judgment of the Executive, (a) significantly reduce the scope of the
duties of the Executive hereunder or (b) significantly reduce the total
potential compensation of the Executive hereunder.  If the Executive determines
in accordance with the preceding sentences that (a) the services required by
the Corporation necessitate that the Executive move his residence from the
Chicago, Illinois area, (b) the duties of the Executive hereunder have been
significantly reduced or (c) the total potential compensation of the Executive
hereunder has been significantly reduced, the Executive, in his sole
discretion, may deem that the Corporation has terminated his services and shall
so notify the Corporation in writing, in which case the Corporation shall be
deemed to have terminated the services of the Executive for all purposes of
this Agreement as of the date specified by the Executive in his notice to the
Corporation.

                                    - 3 -

        3.     Executive's obligations: vacations, automobile.  During the
period of his full-time service under this Agreement, the Executive shall
devote substantially all of his time and energies during business hours to the
supervision and conduct, faithfully and to the best of his ability, of the
business and affairs of the Corporation, and to the furtherance of its
interests, and shall not accept other gainful employment except with the prior
consent of the Chief Executive Officer of the Corporation.  With the approval
of the Chief Executive officer of the Corporation, however, the Executive may
become a director, trustee or other fiduciary of other corporations, trusts or
entities.  The Executive may take four weeks vacation each year with pay.  The
Corporation shall furnish and maintain an automobile for the use of the
Executive consistent with the policy of the Corporation in effect at any time;
provided, however, that at no time shall the policy be materially less generous
than the policy of the Corporation in effect as of January 1, 1996.

        4.     Annual salary. The Corporation shall pay to the Executive for
his services under this Agreement a salary at the rate of $165,600 per year
commencing as of January 1, 1997, payable in equal monthly installments, and
continuing during the period of his full-time service hereunder; provided,
however, that the Corporation shall in good faith review the salary of the

   5

                                    - 4 -

Executive, on an annual basis, with a view to consideration of appropriate
increases in such salary.  If the Executive dies during the period of his
full-time service hereunder, service for any part of the month of his death
shall be considered service for the entire month.

     5.   Period of service and benefits.

     5(a). Period of full-time service.  The period of full-time service of the
Executive under this Agreement shall continue to the third anniversary of the
Effective Date, and for successive 12 month periods thereafter; provided,
however, that the Corporation may terminate at any time the full-time service
of the Executive hereunder by delivering written notice of termination to the
Executive, or the Executive may resign and terminate his full-time service
hereunder at any time after the third anniversary of the Effective Date, by
delivering written notice of his intention to resign to the Corporation at
least 3 months prior to the effective date of such resignation.

     In the event of termination of the Executive by the Corporation, the
Executive shall be entitled to receive his full annual salary and fringe
benefits in effect on the date of receipt of the notice of termination for a
continuing period of 24 months beginning with that month next following the 
month 

   6

                                    - 5 -

during which he ceases to be actively employed. In the event of the
Executive's death, the balance of the continuing salary payments shall be made
to his wife, if surviving, or if not, to his estate in addition to any and all
other benefits payable under this Agreement upon his death.

     In the event of resignation by the Executive as permitted by this
Agreement, the Executive shall be entitled to receive his full annual salary
and fringe benefits in effect on the date of receipt of the notice of
resignation for a continuing period to the effective date of his resignation
but not longer than three months.

     Except as otherwise provided in Section  5(c)(3), continuing fringe
benefits under this Section  5(a) shall be reduced to the extent of any fringe
benefits provided by and available to the Executive from any subsequent
employer but shall not be limited by the terms of any such fringe benefit of a
subsequent employer.

     In the event of termination of the Executive by the Corporation or the
Executive's death or disability, the Executive or his estate shall receive a
cash bonus for the entire fiscal year in which such termination or death occurs
or disability commences.  Such bonus shall be calculated in accordance with the
management incentive compensation program of the Corporation in 

   7

                                    - 6 -

effect from time to time and shall in no event be less than the full target
amount for the Executive for such fiscal year.  The bonus shall be payable in
one lump sum in accordance with and at the time prescribed by the Corporation's
policy for payment of annual bonuses to its executive employees for the year in
which the Executive's termination or death occurs or his disability commences. 
If no policy of the Corporation then exists with regard to calculation and
payment of bonuses, the bonus shall be calculated and paid in accordance with
the policy of the Corporation in effect as of January 1, 1996.

     In addition, in the event of either termination (including, without
limitation, because of the Executive's death or disability) of employment or
resignation, the Executive shall receive payment for accrued but unused
vacation, which payment shall be equitably prorated based on the period of
active employment for that portion of the fiscal year in which the termination
or resignation becomes effective, death occurs, or disability commences, plus
payment for accrued but unused vacation for the prior fiscal year.  Payment for
accrued but unused vacation shall be payable in one lump sum on the effective
date of termination or resignation, the date of death (or as soon thereafter as
practicable) or the date disability commences.

                                    - 7 -

     In the event of termination of the Executive by the Corporation within 24
months following an "Acquisition" of the Corporation (as hereinafter defined),
the benefits to be provided to the Executive and his beneficiaries upon such
termination, regardless of the continued effectiveness of this Agreement or of
the provisions of this Section  5(a), shall be in an amount and character not
less generous than the benefits payable upon a termination of the Executive by
the Corporation as set forth in this Section  5(a).  An "Acquisition" means (I)
any transaction or series of transactions which within a 12-month period
constitute a change of management or control where (i) at least 51 percent of
the then outstanding common shares of the Corporation are (for cash, property
(including, without limitation, stock in any corporation), or indebtedness, or
any combination thereof), redeemed by the Corporation or purchased by any
person(s), firm(s) or entity(ies), or exchanged for shares in any other
corporation whether or not affiliated with the Corporation, or any combination
of such redemption, purchase or exchange, or (ii) at least 51 percent of the
Corporation's assets are purchased by any person(s), firm(s) or entity(ies)
whether or not affiliated with the Corporation for cash, property (including,
without limitation, stock in any corporation) or indebtedness or any
combination thereof, or (iii) the Corporation is merged or consolidated with
another corporation regardless of whether the Corporation is the survivor, or
(II) any substantial equivalent 

   9

                                    - 8 -

of any such redemption, purchase, exchange, change, transaction or series
of transactions, merger or consolidation, constituting such change of
management or control.  For purposes of this paragraph, the term "control"
shall have the meaning ascribed thereto under the Securities Exchange Act of
1934, as amended, and the regulations thereunder, and the term "management"
shall mean the chief executive officer of the Corporation.  For purposes of
clause (I)(ii) above or as appropriate for purposes of clause (II) above, the
Corporation shall be deemed to include on a consolidated basis all subsidiaries
and other affiliated corporations or other entities with the same effect as if
they were divisions.

     The benefits provided for under this section shall be in lieu of, and not
in addition to, any and all benefits to which the Executive and his
beneficiaries may be entitled under any bonus or severance program or policy
adopted by the Corporation from time to time unless otherwise expressly stated
therein.

     5(b). Death benefit.  If the Executive dies during the period of his
full-time service hereunder, his wife, if surviving, or if not, his estate
shall be entitled to receive his full annual salary in effect on the date of
his death for a continuing period of nine months commencing on the first day of
the month immediately following the date of his death.


   10

                                    - 9 -

     5(c)(1). Retirement compensation and obligations.  Upon the retirement or
resignation of the Executive or upon his termination from full-time service
with the Corporation, in either case pursuant to the provisions of this Section
5 hereof, the full-time service obligations of the Executive and the
Corporation to each other under Section  2, 3 and 4 hereof shall cease,
and the Executive shall be entitled to receive benefits and compensation as
specified in this Section  5 hereof.

     5(c)(2). Guarantee of pension benefits.  In addition to the compensation
otherwise provided herein, the Executive and his beneficiaries shall be
entitled to receive the retirement and death benefits they would receive at the
times and under such optional arrangements as the Executive is entitled to
under the terms of any defined benefit retirement or pension plan adopted and
implemented by the Corporation for its executive office employees in effect at
the date of the Executive's retirement, resignation or termination (for
whatever reason) from full-time service with the Corporation or at any time
during the Executive's service with the Corporation (any such plan is referred
to hereafter as the "Plan") (such Plan shall include a lump sum option)
pursuant to the Plan provisions as in effect at the point in time during the
Executive's employment at which the Plan would provide the greatest benefits
for the Executive and his beneficiaries and, in addition, the greatest latitude
in 

   11

                                   - 10 -

choice of options (including, but not limited to, a lump sum option), but in
any event computed without reference to (i) any restrictions in the Plan upon
payments to the Executive, as described in Section 1.401(a)(4)-5(b) of the
Treasury Regulations; (ii) any restrictions in the Plan upon the maximum
contributions to the Plan or upon the maximum benefits payable under the Plan,
as the case may be, pursuant to Section 415 of the Internal Revenue Code of
1986, as in effect at such point in time (the "Code"); (iii) any limitations on
the amount of the Executive's compensation that may be taken into account under
the Plan pursuant to Section 401(a)(17) of the Code or any successor section;
(iv) the limitations on compensation that would exclude any income attributable
to the exercise of the nonqualified stock options granted in replacement of
Equity Appreciation Rights granted under the First Restatement of the Amended
and Restated 1988 Equity Appreciation Rights Plan or the 1989 Equity
Appreciation Rights Plan (hereafter the "EAR Plans"); (v) for purposes of
determining eligibility for a lump sum distribution, any condition under the
Plan considered necessary to receive a lump sum distribution, such as the
submission of medical evidence of reasonable health of the Participant or the
meeting of a specified age or service requirement (in other words the lump sum
distribution shall be an election solely in the discretion of the Executive);
(vi) any forfeiture resulting from an insufficient number of Years of Vesting
Service to be entitled to a fully 

   12

                                   - 11 -

nonforfeitable benefit; or (vii) any other restriction on the Executive's
benefits as determined under the Plan pursuant to the Code, to the Employee
Retirement Income Security Act of 1974, as in effect at such point in time
("ERISA") or to any other law affecting the determination of such benefits. 
However, except as specifically described otherwise in the preceding sentence,
all calculations pursuant to this Section 5(c)(2) of benefits shall be made on
the basis of the actual years of service to the Corporation, including any
Affiliated Corporation and Company as defined under the Plan, and actual
compensation of the Executive taken into account under the applicable Plan
provisions.  In calculating the Executive's compensation and years of service
to the Corporation under the Plan for purposes of benefit accrual and to
determine active employment on any date relevant for any purpose under the
Plan, compensation shall be deemed to include amounts termed severance and
service shall be deemed to include the periods for which the Executive receives
payments termed severance (based on the period over which the severance amount
would have been paid as compensation over the entire period as to which
severance is calculated) even if such amount is paid as a lump sum settlement. 
To the extent that the benefits to which the Executive or his beneficiaries are
entitled under this Section  5(c)(2) are not paid from the Trust under the Plan
or from the IDEX Corporation Supplemental Executive Retirement Plan, the
Corporation shall pay such benefits directly from its general assets.

   13

                                   - 12 -

     If payments are being made, pursuant to this Section  5(c)(2), in the form
of an annuity or other periodic form of distribution, and the portion of the
total amount to be paid from the Trust under the Plan shall thereafter be
reduced after the date such payments have been determined pursuant to the
preceding paragraph, by virtue of the operation of restrictions in the Plan
upon payments to the Executive, as described in Section 1.401(a)(4)-5(b) of the
Treasury Regulations, or by virtue of the termination of the Plan (including
the operation of Section 4045 of ERISA or any successor section) or for any
other reason other than the operation of the provisions of the optional form
selected under the Plan, the Corporation shall increase, in an amount equal to
any such reduction, the amount of the benefit under this Section  5(c)(2) which
is to be paid directly from its general assets, and such increase shall be
prorated over the remaining payments or used to recalculate the annuity
payments, as the case may be.

     If payments are being made or have been made in full, pursuant to this
Section  5(c)(2), but the Executive or any of his beneficiaries is required to
make a payment to the Trustee under the Plan (whether in the form of a loss of
collateral, interest on such collateral or otherwise) as the result of the
application of the restrictions in the Plan upon payments to the Executive, as
described in Section 1.401(a)(4)-5(b) of the Treasury 

   14

                                   - 13 -

Regulations, or by virtue of the termination of the Plan (including the
operation of Section 4045 of ERISA or any successor section) or for any
other reason, the Corporation shall reimburse the Executive or his
beneficiaries, as the case may be, directly from its general assets, for each
such payment to the Trustee, and if the Executive or any of his beneficiaries
does not receive a deduction for federal, state and/or local income tax
purposes for such a payment and/or if such payment would result in the
imposition of any penalty tax because of such repayment, then the amount of
such reimbursement shall be increased by an amount such that after payment by
the Executive or his beneficiaries of all taxes, including, without limitation,
any interest or penalties imposed with respect to such reimbursement, the
Executive or his beneficiaries retain an amount from the Corporation
approximately equal to the amount repaid to the Trustee.

     In the event (I) the Executive requests a lump sum distribution from the
Trustee or Committee under the Plan and is denied the request, regardless of
the reason for the denial, or (II) (i) if the Plan is amended to eliminate the
lump sum distribution option on future benefit accruals or (ii) the Executive
is not otherwise entitled to a lump sum distribution under the Plan terms and,
in the case of (i) or (ii), the Executive states in writing to the Corporation
at any time prior 

   15

                                   - 14 -

to the Executive or his beneficiaries receiving a benefit under the Plan
that he otherwise would have requested the lump sum distribution option, the
Corporation shall pay the Executive, or his beneficiaries, as the case may be,
in cash in a single lump sum benefit, an amount equal to the benefit
hereinbefore determined less any amount received by the Executive or his
beneficiaries from the Plan directly or indirectly in a single payment,
regardless of the form of payment in which the benefit is being paid or is to
be paid under the Plan.  In the case of a benefit provided under this
paragraph, the Corporation shall pay the Executive or his beneficiaries an
additional amount in cash in a single lump sum payment such that after payment
by the Executive or his beneficiaries of all federal, state, and/or local
income taxes (including, without limitation, any interest or penalties imposed
with respect to such taxes) imposed upon such single lump sum payment, the
Executive or his beneficiaries retain an amount that would have been retained
by him or them (without regard to any limitations as described in the first
paragraph of this Section  5(c)(2)) had he or they directly rolled the amount
from the Plan into an individual retirement account.  If the Executive or his
beneficiaries receive the single lump sum payment from the Corporation under
this paragraph, the Executive and his beneficiaries agree to waive and/or
return to the Corporation all benefits to him or them that he or they
subsequently receive from the Plan.  Notwithstanding the 

   16

                                     -15-

preceding sentence, if  the Executive or any of his beneficiaries does not
receive a deduction for federal, state and/or local income tax purposes for
such benefits and/or if such benefits would result in the imposition of any
penalty tax because of such repayment, then the amount of such waiver and/or
return to the Corporation shall be decreased by an amount such that after
payment by the Executive or his beneficiaries of all taxes, including, without
limitation, any interest or penalties imposed with respect to such waiver
and/or return, the Executive or his beneficiaries incur no net expense from
such benefits he or they subsequently receive from the Plan.  For purposes of
this Section, beneficiaries means the beneficiaries as determined under the
Plan.

     Notwithstanding the preceding provisions of this Section  5(c)(2), in
calculating the benefit provided under this Section  5(c)(2) under the terms of
any Plan, compensation shall include in any year any amount otherwise excluded
from compensation in such year as a result of an election to defer income made
pursuant to the provisions of the IDEX Corporation 1996 Deferred Compensation
Plan for Officers and shall exclude in any year any amount that would otherwise
be included in compensation in a year which relates to an amount deferred in a
prior year under the provisions of the IDEX Corporation 1996 Deferred
Compensation Plan for Officers.


   17

                                   - 16 -

        Notwithstanding the preceding provisions of this Section  5(c)(2), in
calculating the benefit provided under this Section  5(c)(2) under the terms of
the Plan, the following rules shall apply:

           (a) In computing average compensation for purposes of any benefit
      formula under the Plan, compensation shall not include any income
      includable in the Executive's income for income tax purposes attributable
      to the exercise of stock options granted in replacement for Equity
      Appreciation Rights under the EAR Plans at any time.

           (b) An additional benefit under this Section  5(c)(2) shall be
      payable in an amount equal to the benefit accrued at the rate provided in
      the Plan's career average formula applied to the income includable in the
      Executive's income for income tax purposes attributable to the exercise
      of stock options granted in replacement of Equity Appreciation Rights
      under the EAR Plans at any time.

        5(c)(3) Medical benefits.  The Executive and/or his wife, as the case
may be, shall be entitled to prompt reimbursement for all medical, dental,
hospitalization, convalescent, nursing, extended care facilities (including,
without limitation, long term care facilities such as

   18

                                   - 17 -

convalescent and nursing homes) and similar health and welfare expenses 
incurred by the Executive (or by his wife in the event of the Executive's death
or disability) for the Executive or for the benefit of his wife or other
dependents (hereinafter collectively referred to as "medical benefits").  Such 
medical benefits shall continue at all times while the Executive is employed by
the Corporation, and thereafter for the remainder of his life or the life of
his wife, whichever shall be the longer time, if (a) the Executive continues in
the employ of the Corporation until the commencement of his 56th year or (b)
the Executive prior to the commencement of his 56th year dies or becomes
disabled while employed by the Corporation or (c) the Executive ceases to be
employed by the Corporation for any reason, whether voluntary or involuntary,
at any time following an Acquisition.  The Corporation may, in its discretion,
insure such medical benefits; provided, however, that such benefits shall not
be affected by the existence or non-existence of any available insurance from
any source, shall not be limited by the terms of any such insurance or the
failure of any insurer to meet its obligations thereunder, shall not limit the
Executive or his wife or other dependents in the choice of any physician,
medical care facility or type of medical expenses in any way, and, except as
provided in the following sentence, shall not be affected by the availability
of any medical benefits provided by and available to the Executive from any
subsequent employer. Such 

   19

                                   - 18 -

medical benefits shall be reduced to the extent of any medical benefits
actually available and actually provided by any subsequent employer to the
Executive, his wife, or other dependents only during the following periods:

           (a) until the commencement of his 56th year if he ceases to be
      employed by the Corporation as a result of his involuntary termination
      following an Acquisition, or

           (b) until the commencement of his 60th year if he ceases to be
      employed by the Corporation as a result of his voluntary termination or
      retirement prior to the commencement of his 60th year.

Without limiting the foregoing, there shall be no such offset in the event of:

           (a) termination for any reason after commencement of the Executive's
      60th year,

           (b) involuntary termination following an Acquisition, and after
      commencement of the Executive's 56th year, or

           (c) the death or disability of the Executive while in the active
      employment of the Corporation.

   20

                                   - 19 -

In any case such reduction in medical benefits shall be only to the extent of
any medical benefits actually provided by and actually available to the
Executive (and/or his wife or other dependents) from any subsequent employer
without cost to the Executive (and/or his wife or other dependents) or subject
to full reimbursement of any such cost by the Corporation to the Executive
(and/or his wife or other dependents), but shall not be limited by the terms of
any such insurance or reimbursement.  For purposes of this Agreement, the term
"medical expenses" shall include, but not be limited to, prescription drugs,
prosthetics, optical care (including corrective lenses) and travel and lodging
associated with medical expenses, with the selection of medical providers and
institutions and related travel and lodging to be solely in the discretion of
the Executive (and/or his wife or other dependents).

     5(d). Confidentiality agreement.  During the course of his employment, the
Executive has had and will have access to confidential information relating to
the lines of business of the Corporation, its trade secrets, marketing
techniques, technical and cost data, information concerning customers and
suppliers, information relating to product lines, and other valuable and
confidential information relating to the business operations of the Corporation
not generally available to the public (the "Confidential Information").  The
parties hereby acknowledge that 

   21

                                   - 20 -

any unauthorized disclosure or misuse of the Confidential Information could
cause irreparable damage to the Corporation. The parties also agree that
covenants by the Executive not to make unauthorized use or disclosures of the
Confidential Information are essential to the growth and stability of the
business of the Corporation.  Accordingly, the Executive agrees to the
confidentiality covenants set forth in this section.

     The Executive agrees that, except as required by his duties with the
Corporation or as authorized by the Corporation in writing, he will not use or
disclose to anyone at any time, regardless of whether before or after the
Executive ceases to be employed by the Corporation, any of the Confidential
Information obtained by him in the course of his employment with the
Corporation.

     The Executive agrees that since irreparable damage could result from his
breach of the covenants in this Section  5(d) of this Agreement, in addition to
any and all other remedies available to the Corporation, the Corporation shall
have the remedies of a restraining order, injunction or other equitable relief
to enforce the provisions thereof.  The Employee consents to jurisdiction in
Lake County, Illinois on the date of the commencement of any action for
purposes of any claims under this Section  5(d).  In addition, the Executive
agrees that the issues in any 

   22

                                   - 21 -

action brought under this section will be limited to claims under this
section, and all other claims or counterclaims under other provisions of this
Agreement will be excluded.

        6.     Compensation under this Agreement not exclusive.  Except as
expressly stated to the contrary in this Agreement, the compensation and
benefits payable by the Corporation to the Executive under the provisions of
this Agreement shall be in addition to and separate and apart from such
additional compensation or incentives and such retirement, disability or other
benefits as the Executive may be entitled to under any present or future extra
compensation or bonus plan, stock option plan, share purchase agreement,
pension plan, disability insurance plan, medical insurance plan, life insurance
program, or other plan or arrangement of the Corporation established for its
executives or employees, and the provisions of this Agreement shall not affect
any such compensation, incentives or benefits.  The Board of Directors of the
Corporation, in its discretion, may award the Executive such additional
compensation, incentives or benefits, pursuant to such plans or otherwise, as
it may from time to time determine.

        7.     Termination of this Agreement.  This Agreement shall terminate
when the Corporation has made the last payment provided for hereunder;
provided, however, that the obligations 

   23
                                   - 22 -

set forth under Section  5(d) of this   Agreement shall survive any such
termination and shall remain in full force and effect. Without the written
consent of the Executive, the Corporation shall have no right to terminate this
Agreement prior thereto.  In the event the Executive, or his beneficiaries, as
the case may be, and the Corporation shall disagree as to their respective
rights and obligations under this Agreement, and the Executive or his
beneficiaries are successful in establishing, privately or otherwise, that his
or their position is substantially correct, or that the Corporation's position
is substantially wrong or unreasonable, or in the event that the disagreement
is resolved by settlement, the Corporation shall pay all costs and expenses,
including counsel fees, which the Executive or his beneficiaries may incur in
connection therewith directly to the provider of the services or as may
otherwise be directed by the Executive or his beneficiaries. The Corporation
shall not delay or reduce the amount of any payment provided for hereunder or
setoff or counterclaim against any such amount for any reason whatever; it is
the intention of the Corporation and the Executive that the amounts payable to
the Executive or his beneficiaries hereunder shall continue to be paid in all
events in the manner and at the times herein provided.  All payments made by
the Corporation hereunder shall be final and the Corporation shall not seek to
recover all or any part of any such payments for any reason whatsoever.

                                   - 23 -

     8.     Additional payments by Corporation.

        (a)  Notwithstanding anything in this Agreement or any other agreement
to the contrary, in the event it shall be determined that any payment or
distribution by the Corporation or any affiliate (as defined under the
Securities Act of 1933, as amended, and the regulations thereunder) thereof or
any other person to or for the benefit of the Executive, whether paid or
payable or distributed or distributable pursuant to the terms of this
Agreement, pursuant to all non-qualified stock option plans of the Corporation
now or hereafter in effect pursuant to the IDEX Corporation Supplemental
Executive Retirement Plan, pursuant to the IDEX Corporation 1996 Deferred
Compensation Plan for Officers, pursuant to any other plan of deferred
compensation, or pursuant to any other agreement or arrangement with the
Corporation or any affiliate thereof now or hereafter in effect (a "Payment"),
would be subject to the excise tax imposed by Section 4999 of the Code, or any
successor statute thereto, or any interest or penalties with respect to such
excise tax (such excise tax, together with any such interest and penalties, are
hereinafter collectively referred to as the "Excise Tax"), then the Executive
shall be entitled to receive an additional payment (a "Gross-Up Payment") in an
amount such that after payment by the Executive of all taxes (including,
without limitation, any interest or penalties imposed with respect to such
taxes and any 

   25

                                   - 24 -

Excise Tax) imposed upon the Gross-Up Payment, the Executive retains an
amount of the Gross-Up Payment equal to the Excise Tax imposed upon the
Payments.

        (b)  The Executive and/or the Corporation shall notify each other in
writing as soon as practicable of any claim by the Internal Revenue Service
that, if successful, would require the payment by the Corporation of the
Gross-Up Payment.  Such notification shall state the nature of such claim and
the date on which such claim is requested to be paid.  Neither the Executive
nor the Corporation shall pay such claim for taxes prior to the expiration of
the thirty-day period following the date on which the notice is given (or such
shorter period ending on the date that any payment of taxes with respect to
such claim is due).  If the Executive or Corporation (hereafter the "Notifying
Party")  notifies the other party in writing prior to the expiration of such
period that he or it desires to contest such claim, such other party shall take
such action, in connection with contesting such claim as the Notifying Party
shall reasonably request in writing from time to time, including, without
limitation, accepting legal representation with respect to such claim by an
attorney selected by the Notifying Party and approved by the other party,
provided, however, that the Corporation shall bear and pay directly all costs
and expenses (including additional interest and penalties and counsel fees as
submitted) incurred in 

   26

                                   - 25 -

connection with such contest and shall indemnify and hold the Executive
harmless, on an after-tax basis, for any Excise Tax or income tax, including
interest and penalties with respect thereto, imposed as a result of such
representation and payment of costs and expenses.  Furthermore, if the
Corporation is the Notifying Party, the Corporation's control of the contest
shall be limited to issues with respect to which a Gross-Up Payment would be
payable hereunder and the Executive shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any
other taxing authority.

        9.     Assurances on liquidation.  The Corporation agrees that until
the termination of this Agreement as above provided, it will not voluntarily
liquidate or dissolve, or enter into or be a party to any other transaction the
effect of which would be to materially reduce the net assets or operations of
the Corporation, without first making a written agreement with the Executive or
other beneficiary, satisfactory to and approved by him or such beneficiary in
writing within 30 days of receipt of a notice from the Corporation of such
proposed liquidation, dissolution or other transaction, in fulfillment of or in
lieu of its obligations to him or such beneficiary under this Agreement or any
other agreement, plan, policy or program of the Corporation or, in the absence
of such agreement, paying him or such beneficiary in a lump sum settlement of
all such obligations 

   27

                                   - 26 -

prior to such proposed liquidation, dissolution or other transaction. 
Notwithstanding anything in the preceding sentence to the contrary, in
the event that pursuant to the preceding sentence the Corporation is obligated
to pay to the Executive or such beneficiary in a lump sum settlement all of the
obligations of the Corporation to the Executive or such beneficiary under this
Agreement or any other agreement, plan, policy or program of the Corporation,
the Executive or, in the event of his death or inability to act, his wife or,
if not surviving, his eldest surviving child (or in the event of their
inability to act, such person who has the legal power to act on their behalf),
shall have the right, in his or her sole discretion, to elect not to receive a
lump sum settlement of the obligations of the Corporation to the Executive or
other beneficiary under Section  5(c)(3) of this Agreement and, in lieu
thereof, to receive a guaranty (including, without limitation, a letter of
credit), in form and substance satisfactory to the Executive or other
beneficiary, as the case may be, in his or her sole discretion, of the payment
of such obligations from any entity satisfactory to the Executive or other
beneficiary, as the case may be, in his or her sole discretion.  Any lump sum
settlement shall reflect a reasonable assumption of cost-of-living adjustments,
if appropriate to such obligation, and shall be determined using the mortality
assumptions of the "applicable mortality table" under Section 417(e) of the
Code and either (i) the interest rate that 

   28

                                   - 27 -

would be used (as of the date of payment) by the Pension Benefit Guaranty
Corporation for purposes of valuing a lump sum distribution upon a plan
termination on the January 1 of the calendar year in which the single sum is
paid or (ii) the "applicable interest rate" under Section 417(e) of the Code,
determined as of the first month of the calendar year in which the single sum
is paid, whichever would produce the greater single sum amount.  For purposes
of this Subsection, the Corporation shall be deemed to include on a
consolidated basis all subsidiaries and other affiliated corporations or other
entities with the same effect as if they were divisions.

        10.     Definitions.  For purposes of this Agreement, the term "year"
shall mean fiscal year, the term "dependents" shall have the same meaning as
pursuant to Section 152 of the Code and the terms "his 56th year" and "his 60th
year" shall mean immediately following the Executive's 55th birthday and 59th
birthday respectively.  For purposes of this Agreement, disability shall mean a
disability which is, or has the potential to be, total and permanent and
because of which the Executive is or may become physically or mentally unable
to substantially perform his regular duties as an Executive of the Corporation.
Any question as to the existence, extent or potentiality of disability of the
Executive upon which the Executive and the Corporation cannot agree shall be
determined by a qualified 

   29

                                   - 28 -

independent physician selected by the Executive and reasonably acceptable to 
the Corporation (or, if the Executive is unable to make such selection, it 
shall be made by any adult member of his immediate family).  The determination
of such physician made in writing to the Corporation and to the Executive 
shall be final and conclusive for all purposes of this Agreement.

        11.     Amendments.  This Agreement may not be amended or modified
orally, and no provision hereof may be waived, except in a writing signed by
the parties hereto, and specifically the agreement of any beneficiary, wife,
dependents or other potential or actual third party beneficiary shall not be
required, except as specifically provided for in this Agreement.

        12.     Assignment.  This Agreement cannot be assigned by either party
hereto except with the written consent of the other.

        13.     Binding effect.  This Agreement shall be binding upon and inure
to the benefit of the personal representatives and successors in interest of
the Executive and any successors in interest of the Corporation.  In addition
to inuring to the benefit of the Executive, Sections  5(a) and 5(b) are
intended to inure to the benefit of the Executive's beneficiaries, Section
5(c)(2) is intended to inure to the benefit of the Executive's beneficiaries,
to the extent contemplated in that provision, 

   30

                                   - 29 -

Section  5(c)(3) is intended to inure to the benefit of the Executive's wife
and his dependents, and Section 7, Section  8 and Section  9 are intended
to inure to the benefit of the Executive's beneficiaries; such provisions shall
be enforceable by the aforesaid beneficiaries, wife and/or dependents, as the
case may be, who upon the Executive's death shall be deemed successors in
interest.

        14.     Choice of law.  This Agreement shall be governed by the law of
the State of Illinois (excluding the law of the State of Illinois with regard
to conflicts of law) as to all matters, including but not limited to matters of
validity, construction, effect and performance.

        15.     Notice.  Except as otherwise provided in this Agreement, all
notices and other communications given pursuant to this Agreement shall be
deemed to have been properly given if personally delivered or mailed, addressed
to the appropriate party at the address of such party as shown at the beginning
of this Agreement, postage prepaid, by certified mail or by Federal Express or
similar overnight courier service.  A copy of any notice sent pursuant to this
section shall also be sent to Hodgson, Russ, Andrews, Woods & Goodyear, 1800
one M&T Plaza, Buffalo, New York, 14203, Attention: Richard E. Heath, Esq. and
Dianne Bennett, Esq.  Any party may from time to time designate by written
notice given in accordance with the provisions of this 

   31

                                    - 30 -

paragraph any other address or party to which such notice or communication
or copies thereof shall be sent.

        16.     Severability of provisions.  In case any one or more of the
provisions contained in this Agreement shall be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be effected or
impaired thereby and this Agreement shall be interpreted as if such invalid,
illegal or unenforceable provision was not contained herein.

        17.     Titles.  Titles are provided herein for convenience only and
are not to serve as a basis for interpretation or construction of this
Agreement.

                                   - 31 -

     IN WITNESS WHEREOF, the Executive has hereunto set his hand and the
Corporation has caused this Agreement to be executed in its name and on its
behalf as of the date first above written.
