SECOND AMENDMENT TO THE
                          PENSION PLAN FOR EMPLOYEES OF
                              AMPHENOL CORPORATION

      Amendment made this 4th day of February, 1999, to the Pension Plan for
Employees of Amphenol Corporation as amended and restated effective December 31,
1997, (the "Plan") by resolution of the Board of Directors Amphenol Corporation
(the "Employer");

      WHEREAS, Pursuant to Article XII the Employer has the right to amend the
plan;

      WHEREAS, The Employer desires to amend the Plan to comply with the
provisions of the Retirement Protection Act of 1994, which was part of the
General Agreement on Tariffs and Trade ("GATT"), the Uniformed Services
Employment and Reemployment Rights Act of 1994 ("USERRA"), The Small Business
Job Protection Act ("SBJPA") and the Taxpayer Relief Act of 1997 ("TRA '97");

      NOW, THEREFORE, the Plan is hereby amended as follows:

                                   SECTION ONE
                           HIGHLY COMPENSATED EMPLOYEE

      (1) "Highly Compensated Employee" means any Employee who:

            (a) was a 5-percent owner at any time during the Plan Year or the
preceding year, or

            (b) for the preceding year had Compensation from the Employer in
excess of $80,000.

      The provisions of this Section shall be effective for Plan Years beginning
after December 31, 1996, except that for purposes of determining whether an
Employee is a


Highly Compensated Employee for the Plan Year beginning in 1997, these
provisions shall be treated as having been in effect for Plan Years beginning in
1996.

                                   SECTION TWO

                        REPEAL OF FAMILY AGGREGATION RULE

      For all purposes of the Plan, if an individual is employed by the Employer
and is a member of the family of a 5-percent owner, then such individual shall
be considered a separate Employee and any Compensation paid to such individual
and any applicable contribution or benefit on behalf of such individual shall be
treated as if it were attributable solely to that individual. Except as provided
in Treasury Regulations, this provision shall be applied in determining the
Compensation of or contributions or benefits on behalf of any Employee for
purposes of any section with respect to which a Highly Compensated Employee is
defined by reference to Section 414(q) of the Code.

      The provisions of this Section shall be effective for Plan Years beginning
after December 31, 1996. For purposes of determining whether an Employee is a
Highly Compensated Employee for the 1997 Plan Year only, the family aggregation
rules are considered to have been repealed for 1996.

                                  SECTION THREE

        COMBINED DEFINED CONTRIBUTION/DEFINED BENEFIT PLAN LIMIT

      For Limitation Years beginning after December 31, 1999, if an Employee is
(or has been) a Participant in one or more defined benefit plans and one or more
defined contribution plans maintained by the Employer, the sum of the defined
benefit plan fraction and the defined contribution plan fraction for any
limitation year may exceed 1.0. After the above effective date, only the
limitations of Code Section 415(b) will apply to this defined benefit plan. No
adjustment need be made to either the defined benefit or defined


                                                                               2


contribution fraction in the event that the combined defined benefit/defined
contribution limit exceeds 1.0 in any Limitation Year.

                                  SECTION FOUR

                                 LEASED EMPLOYEE

      For all purposes in the Plan, "Leased Employee" means any person who is
not a common law employee of the recipient and who provides services to the
recipient if:

      (1) such services are provided pursuant to an agreement between the
recipient and any other person (in this Section referred to as the "Leasing
Organization");

      (2) such person has performed such services for the recipient (or for the
recipient and related persons) on a substantially full-time basis for a period
of at least one (1) year; and

      (3) such services are performed under primary direction or control by the
recipient.

      The provisions of this Section shall be effective for Plan Years beginning
after December 31, 1996.

provided in accordance with Section 414(u) of the Code.

            The provisions of this Section shall be effective December 12, 1994.


                                                                               3


                                   SECTION SIX

                         REQUIRED MINIMUM DISTRIBUTIONS

      The term "required beginning date" means the pre-SBJPA required beginning

after December 31, 1996.

                                  SECTION SEVEN

                                  KEY EMPLOYEE

      "Key Employee" shall mean an Employee who, at any time during the Plan
Year or any of the four (4) preceding Plan Years, is

      (1) an officer of the Employer having Compensation greater than fifty
percent (50%) of the amount in effect under Section 415(b)(1)(A) of the Code for

employees, or (ii) the greater of ten percent (10%) of the employees or three
(3) employees will be treated as officers. For purposes of paragraph (b),if two

greater Compensation from the Employer will be treated as having a larger

purposes of determining the number of officers taken into account under
paragraph (a), employees described in Section 414(q) (5) of the Code will be
excluded.

                                  SECTION EIGHT

                       OPTION TO WAIVE 30-DAY QJSA NOTICE

      The plan shall provide Participants with the written explanation of the
Qualified Joint and Survivor Annuity required by Code Section 417(a)(3) no less
than 30 days and no more than 90 days before the Annuity Staffing Date. A
distribution to a Participant may commence less than 30 days after the notice
required by Code Section 417(a) (3) is given, provided that the following
requirements are met:


                                                                               5


      (1) The Plan Administrator provides information to the Participant clearly
indicating that the Participant has a right to a period of at least 30 days to
consider whether to waive the Qualified Joint and Survivor Annuity and consent
to a form of distribution other than a Qualified Joint and Survivor Annuity.

      (2) The Participant is permitted to revoke an affirmative distribution
election at least until the Annuity Staffing Date, or, if later, at any time
prior to the expiration of the 7-day period that begins the day after the
explanation of the Qualified Joint and Survivor Annuity is provided to the
Participant,

      (3) The Annuity Starting Date is after the date that the explanation of
the Qualified Joint and Survivor Annuity is provided to the Participant.
However, the Annuity Starting Date may be before the date that any affirmative
distribution election is made by the Participant and before the date that the
distribution is permitted to commence under (4) below, and

      (4) Distribution in accordance with the affirmative election does not
commence before the expiration of the 7-day period that begins the day after the
explanation of the Qualified Joint and Survivor Annuity is provided to the

                                  SECTION NINE

             APPLICABLE MORTALITY TABLE AND APPLICABLE INTEREST RATE

      Effective with the later of the adoption date or the first day of the Plan
Year beginning after December 31, 1997, the mortality table and the interest
rate used for the purposes of determining an Actuarial Equivalent amount (other
than non-decreasing life annuities payable for a period not less than the life
of a Participant or, in the case of a Qualified Pre-Retirement Survivor Annuity,
the life of the surviving spouse) shall be the "Applicable Mortality Table" and
the "Applicable Interest Rate" described below.


                                                                               6


      (1) The "Applicable Mortality Table" means the mortality table prescribed
by the Secretary of the Treasury. Such table shall be based on the prevailing
commissioners' standard table (described in Code Section 807(d)(5)(A)) used to
determine reserves for group annuity contracts issued on the date as of which
present value is being determined (without regard to any other subparagraph of
Code Section 807(d)(5)).

      (2) The "Applicable Interest Rate" means the annual rate of interest on
30-year Treasury securities determined as of the second calendar month (the
lookback month) preceding the first day of the Plan Year during which the
Annuity Starting Date occurs. The Applicable Interest Rate shall remain constant
for the Plan Year stability period.

      Notwithstanding anything contained in this amendment or the Plan to the
contrary, a Participant's Accrued Benefit shall not be considered to be reduced
in violation of Code Section 411(d) (6) merely because of the above changes in
the interest rate and mortality assumption used to calculate Actuarial
Equivalent amounts.

      The provisions of this Section shall be effective as of the Limitation
Year beginning after December 31, 1997.

                                   SECTION TEN

                  ADJUSTMENTS TO ANNUAL BENEFIT AND LIMITATIONS

      (1) If benefits commence prior to age 62, the dollar limitation under Code
Section 415(b) shall be the Actuarial Equivalent of the Participant's limitation
for benefits commencing at age 62, reduced for each month by which benefits
commence before the month in which the Participant attains age 62. In order to
determine Actuarial Equivalents for this purpose, the lesser of the Actuarial
Equivalent amount computed using the Plan interest rate and Applicable Mortality
Table, and the amount computed using 5% interest and the Applicable Mortality
Table shall be used. If the annual benefit is paid in a form other than a
non-decreasing life annuity payable for a period not less than the life of a


                                                                               7


Participant (or, in the case of a Qualified Pre-Retirement Survivor Annuity, the
life of the surviving spouse,) the Actuarial Equivalent amount shall be
determined by substituting the Applicable Interest Rate for five percent (5%) in
the preceding sentence.

      (2) Further, for purposes of adjusting the benefit to a straight life
annuity, the equivalent Annual Benefit shall be the greater of the equivalent
Annual Benefit computed using the Plan interest rate and the Applicable
Mortality Table, and the equivalent Annual Benefit computed using five-percent
(5%) interest rate assumption and the Applicable Mortality Table. If the Annual
Benefit is paid in a form other than a non-decreasing life annuity payable for a
period not less than the life of a Participant or, in the case of a Qualified
Pre-Retirement Survivor Annuity, the life of the surviving spouse, the
Applicable Interest Rate shall be substituted for five percent (5%) in the
preceding sentence.

                                 SECTION ELEVEN

                   IMMEDIATE CASH-OUT FOR DE MINIMIS BENEFITS

      (1) If the Actuarial Equivalent present value of a Participant's vested
Accrued Benefit derived from Employer and Employee contributions does not exceed
or did not at the time of any prior distribution exceed $5,000, the Participant
will receive a single sum distribution cash or property of the Actuarial
Equivalent value of the entire rested Accrued Benefit.

      (2) The monthly payments made from the Plan to Highly Compensated
Employees and to former Highly Compensated Employees who are among the twenty-
five most highly paid Employees with the greatest Compensation in the current
or any prior year, shall be limited to an amount equal to the monthly payments
that would be made on behalf of the Employee under a Straight Life Annuity that
is the Actuarial Equivalent of the sum of the Employee's other benefits under
the Plan (other than a social security supplement within the meaning of Section
1.4(a)-7(c)(4)(ii) of the Regulations), and the amount the Employee is entitled
to receive under a social security supplement.


                                                                               8


      The provisions of this Section shall only apply to Accrued Benefits
payable by reference to an Exhibit which provided for the immediate cash-out of
de minimis benefits prior to January 1, 1998.

      The provisions of this Section shall be effective for Plan Years beginning
after December 31, 1997.

      The aforesaid Plan is ratified and confirmed in each and every other
respect.
