ARTICLE I. ESTABLISHMENT OF THE PLAN

1.1 ESTABLISHMENT AND RESTATEMENT

Boehringer Mannheim U.S. Holdings, Inc. previously established and maintained a
supplemental benefits plan on behalf of its subsidiaries and other affiliated
corporations. Such plan was last amended and restated effective as of January 1,

Corange U.S. Holdings, Inc., and the plan became known as the Corange U.S.
Holdings, Inc. Supplemental Retirement Plan (Plan No. 1). Effective as of
October 1, 1996, the assets and liabilities held under this plan which related
to Participants employed by Boehringer Mannheim Corporation or affiliates of
Boehringer Mannheim Corporation were spun off and transferred to a new plan
known as the Boehringer Mannheim Corporation Supplemental Retirement Plan (Plan
No. 1) and a related trust agreement. The original plan is hereby amended and
restated effective as of October 1, 1996, and shall be renamed the "DePuy, Inc.
Supplemental Retirement Plan, Plan No. 1" (the "Plan"). The Plan sponsor shall
be changed from Corange U.S. Holdings, Inc. to DePuy, Inc.

1.2 PURPOSE

The Plan is intended to ensure a competitive level of retirement benefits to a
select group of senior executives of DePuy in order to attract and retain
talented executives.

Participants in the Plan shall be selected by the CEO or the Board from senior
executives within the DePuy Affiliated Group. Selections will be based upon the
CEO's or the Board's determination of the past, present, and expected future
contributions by executives to the long-term performance and growth of DePuy and

     annual amount computed in the same manner as Supplemental Retirement
     Benefits under subsection (a). The following calculations shall be applied
     in determining the Supplemental Early Retirement Benefit:
     (1)  The amount determined in section 5.1(a)(1) (before the application of
          the offset in section 5.1(a)(2)) shall be reduced to reflect the early
          commencement of the Benefit. The reduction for early commencement
          shall be .25 percent for each of the first 60 months and .41667
          percent for each of the next 60 months (if any), that commencement of
          the Supplemental Early Retirement Benefits precedes the Participant's
          Normal Retirement Date.
     (2)  Additionally, if the Participant entered the Predecessor Plan after
          January 1, 1992 and has completed fewer than ten complete years of
          service within the DePuy Affiliated Group, his Supplemental Early
          Retirement Benefit (after reduction for early commencement) will be
          further reduced. The reduction shall be .41667 percent for each whole
          or fractional month that the Participant's years of service are less
          than ten years. This service reduction (in addition to the early
          commencement reduction)

                                       10

<PAGE>
 
          shall be applied to the amount determined under section 5.1(a)(1)
          before the application of the offset in section 5.1(a)(2), but after
          the application of the reduction in paragraph (1).
     (3)  Instead of the reductions described in paragraph (2), if the
          Participant entered the Plan before January 1, 1992 and has completed
          fewer than five complete years of service with Boehringer, his
          Supplemental Early Retirement Benefit (after reduction for early
          commencement) will be further reduced. The reduction shall be .833
          percent for each whole or fractional month that the Participant's
          years of service are less than five years, and this service reduction
          (in addition to the early commencement reduction) shall be applied to
          the amount determined under section 5.1(a)(1) before the application
          of the offset in section 5.1(a)(2), but after the application of the
          reduction in paragraph (1).

(c)  A Participant who incurs a Disability while employed within the DePuy
     Affiliated Group shall be eligible to receive Supplemental Disability
     Retirement Benefits under the Plan if the Participant completed five years
     of service within the DePuy Affiliated Group or attained age 60 prior to
     the Participant's Disability Retirement Date. If a Participant is not
     enrolled in the Long-Term Disability Plan, the Participant shall receive no
     Supplemental Disability Retirement Benefits under this Plan. The
     Supplemental Disability Retirement Benefits will begin as soon as practical
     following the Participant's Disability Retirement Date. A Participant's
     Supplemental Disability Retirement Benefit will be an annual amount,
     payable for the Participant's lifetime, equal to--
     (1)  sixty percent of the Participant's Final Average DePuy Income, reduced
          by
     (2)  the sum of--
          (A)  the amount the Participant would be eligible to receive under the
               Long-Term Disability Plan (assuming the Participant selected the
               highest level of coverage available under such Plan); plus
          (B)  the sum of the Participant's Other Retirement Income and the
               benefit payable to the Participant under the RIP Plan.

The Participant's Supplemental Disability Retirement Benefit will not be reduced
to reflect commencement thereof before the Participant's Normal Retirement Date
or the Participant's failure to complete five years of service within the DePuy
Affiliated Group. If a Participant recovers from a Disability, his Supplemental
Disability Retirement Benefits shall cease. Upon his subsequent Retirement or
other termination of employment, he

                                       11

<PAGE>
 
shall receive a benefit pursuant to the remaining provisions of this Plan, to
the extent that he has satisfied the Plan requirements for such Benefits.

5.2 DEATH BENEFITS

(a)  The Surviving Spouse of a Participant will be eligible to receive a death
     benefit under this section 5.2(a) if the Participant dies while employed by
     DePuy and prior to the commencement of benefits under section 5.1, but
     after either--
     (1)  completing five years of service within the DePuy Affiliated Group; or
     (2)  attaining age 60.

The amount of such benefit will be an annual amount equal to 50 percent of the
annual amount of Supplemental Retirement Benefits which would have been payable
to the Participant, based on his DePuy Income at his death, if the Participant
had retired on his Normal Retirement Date and been entitled to receive benefits
under section 5.1(a). Such payments will begin on the first day of the month
next following the date of the Participant's death.

(b)  The Surviving Spouse of a Participant will be eligible to receive a death
     benefit under this section 5.2(b) if the Participant dies after the
     commencement of Benefits under section 5.1 or 5.3. The amount of such
     benefit will be an annual amount equal to 50 percent of the annual amount
     of the Benefits payable to the Participant during his lifetime; provided,
     however, that for purposes of determining the amount of death benefit
     payable, the Benefits payable during the Participant's lifetime shall be
     recalculated by excluding from Other Retirement Income any primary Social
     Security benefit payable to the Surviving Spouse by reason of the
     Participant's death and by including any payments to the Surviving Spouse
     under the Long-Term Disability Plan. Such payments will begin on the first
     day of the month next following the date of the Participant's death.

(c)  The Surviving Spouse of a Participant will be eligible to receive a death
     benefit under this section 5.2(c) if the Participant dies after termination
     of employment within the DePuy Affiliated Group and prior to the
     commencement of Supplemental Deferred Vested Benefits under section 5.3,
     but after completing ten years of service within the DePuy Affiliated Group
     (five years if the Participant entered the Plan before January 1, 1992).
     The amount of such benefit will be an annual amount equal to 50 percent of
     the annual amount of Supplemental Deferred Vested Benefits which would have
     been payable to the Participant under section 5.3 on the first day of the
     month next following the Participant's sixty-fifth birthday. Such payments
     will

                                       12

<PAGE>
 
     begin on the first day of the month next following the date the Participant
     would have attained his sixty-fifth birthday.

(d)  Payments under this section shall be continued to the Surviving Spouse
     until the Surviving Spouse's death.

5.3 SUPPLEMENTAL DEFERRED VESTED BENEFITS

A Participant whose Employment within the DePuy Affiliated Group is terminated
after completing ten years of service within the DePuy Affiliated Group (five
years if the Participant entered the Plan before January 1, 1992) but before
becoming eligible for Supplemental Retirement Benefits or Supplemental Early
Retirement Benefits, shall be eligible to receive Supplemental Deferred Vested
Benefits under the Plan. The Supplemental Deferred Vested Benefits will begin on
the first day of the month coincident with or next following the Participant's
sixty-fifth birthday. A Participant's Supplemental Deferred Vested Benefit will
be an annual amount computed in the same manner as Supplemental Retirement
Benefits under section 5.1(a), based on his Final Average DePuy Income at his
termination of employment and his projected age 65 Other Retirement Income and
benefit under the RIP Plan.

5.4 COMMENCEMENT OF PAYMENTS

(a)  Except as otherwise specified in this section 5.4, benefits payable under
     sections 5.1, 5.2, and 5.3 will commence on the dates specified therein.

(b)  A Participant eligible for a benefit under 5.3 or a Surviving Spouse
     eligible for a benefit under section 5.2(c) may request earlier
     commencement of such benefit. The Administrator may allow Benefits payable
     with respect to the Participant or Surviving Spouse to commence at any time
     after the Participant attains (or would have attained) age 55.

(c)  The Administrator may grant early commencement of benefits upon the written
     petition of the Participant or, if the Participant is deceased, the
     Participant's Surviving Spouse. The approval or denial of such petition
     shall be in the sole discretion of the Administrator. However, such
     petition may not be approved unless the Participant or Surviving Spouse can
     demonstrate either--

     (1)  proof of financial need;
     (2)  that such payment is in the best interest of DePuy; or
     (3)  that such payment will not result in a significant financial detriment
          to DePuy.

     If benefits commence early under this section, they shall be reduced to

                                       13

<PAGE>
 
     reflect the early commencement thereof and shall be the Actuarial
     Equivalent of the Benefits otherwise payable under the Plan.

5.5 FORM OF PAYMENTS

(a)  Benefit payments under the Plan shall normally be made for the life of the
     Participant and his Surviving Spouse, as described elsewhere in this
     Article V. However, upon the written petition of the Participant (or the
     Participant's Surviving Spouse if the Participant is dead), the
     Administrator may provide for all or any part of the benefits payable with
     respect to a Participant to be made in a single lump sum payment. The
     approval or denial of such petition shall be in the sole discretion of the
     Administrator; provided, however, such petition may not be approved unless
     the Participant (or Surviving Spouse) can demonstrate either--
     (1)  proof of financial need;
     (2)  that such payment is in the best interest of DePuy; or
     (3)  that such payment will not result in a significant financial detriment
          to DePuy.

     As a condition of the Administrator's approval, a Participant or Surviving
     Spouse who requests a lump sum payment, shall execute such other documents
     and agreements as are consistent with the terms of this Plan as the
     Administrator may impose.

(b)  Lump sum payments under this section shall be the Actuarial Equivalent of
     the Benefits payable with respect to the Participant or Surviving Spouse.

5.6 CALCULATION OF OFFSETS AND ACTUARIAL EQUIVALENCE

(a)  The Administrator is authorized to interpret the terms of the Plan and
     calculate all Benefits payable under the Plan. Such interpretations shall
     comply with the rules contained in this section. Such calculations shall be
     made by, or with the guidance of, the Independent Actuary. However,
     subsection (d) shall only apply to Participants who entered the Plan after
     January 1, 1992.

(b)  The offset under this Plan for a married Participant's Other Retirement
     Income and under the RIP Plan shall be calculated as a 50 percent joint and
     survivor annuity (with the Participant's Surviving Spouse as the contingent
     annuitant) beginning at the later of--
     (1)  the Participant's Retirement Date; or
     (2)  the earliest date that the Other Retirement Income or RIP payments are
          available.

                                       14

<PAGE>
 
          The offset under this Plan for an unmarried Participant's Other
          Retirement Income and under the RIP Plan shall be calculated as a
          single life annuity beginning on the later of--
          (A)  the Participant's Retirement Date or
          (B)  the earliest date that the Other Retirement Income or RIP Plan
               payments are available.

          Such annuities shall be the Actuarial Equivalent of the amount of
          Other Retirement Income or the amount under the RIP Plan actually
          payable (or paid) to the Participant.

(c)  In the case of a Participant (or his Surviving Spouse) who is receiving
     payments under this Plan in a lump sum--
     (1)  If the Participant's Other Retirement Income or benefit under the RIP
          Plan is either maintained in an individually maintained account or is
          paid as a lump sum, then the offset for the Other Retirement Income or
          the benefit under the RIP Plan (as applicable) shall be determined on
          the basis of such account balance or lump sum as of the Retirement
          Date.
     (2)  If the Participant's Other Retirement Income is maintained under a
          defined benefit plan, then the offset for the Other Retirement Income
          shall be determined as of the date payment of the lump sum under this
          Plan is payable.

(d)  If the payment of Other Retirement Income begins before the payment of
     Benefits under this Plan, the offset for the Other Retirement Income shall
     be based on the sum of--
     (1)  the amount of such Other Retirement Income payments made when Benefits
          are payable under this Plan and
     (2)  the annuity equivalent of all payments made before Benefits are
          payable under this Plan, plus interest thereon.

     For purposes of this subsection (d), interest on any payments of Other
     Retirement Income shall be based on 120 percent of the interest rate used,
     by the Pension Benefit Guaranty Corporation, for valuing immediate
     annuities upon termination of defined benefit plans. The interest rate used
     shall be based on such PBGC rates as in effect on the first day of each
     Plan Year for the period between payment of the Other Retirement Income and
     the commencement of Benefits under this Plan.

(e)  For purposes of applying this section 5.6--
     (1)  If a benefit under this Plan is payable as a lump sum, a Participant's
          primary Social Security benefit will be based on the law in effect on
          his Retirement Date and will be determined on the assumption that the
          maximum Social Security benefits will increase at an annual rate equal
          to the Assumed Interest Rate in


                                       15
<PAGE>
 
          effect at the date on which payment of a Participant's Benefits
          commence, minus 200 basis points.
     (2)  If a benefit under this Plan is payable as an annuity beginning before
          a Participant's sixty-second birthday, the Participant's primary
          Social Security benefit will equal the maximum primary Social Security
          benefit based on the law in effect on the later of the Participant's
          Retirement Date or the Participant's sixty-second birthday.

(f)  In calculating Disability retirement benefits under section 5.3, the Social
     Security benefit used under paragraph (3) will be based on the actual
     Social Security disability award to the Participant.

(g)  The offset under this Plan for benefits under any defined benefit
     retirement arrangement shall be calculated by the Administrator, in its
     sole discretion, consistent with section 5.6(b) above.

(h)  For purposes of section 5.1(c) and section 5.2(b), the offsets for amounts
     payable under the Long-Term Disability Plan shall only be effected for the
     calendar months in which amounts are actually payable under the Long-Term
     Disability Plan.

5.7 REDUCTIONS FOR CERTAIN SURVIVING SPOUSES

If a Surviving Spouse is entitled to Benefits under this Article V, and if the
Surviving Spouse is more than ten years younger than the Participant, the amount
otherwise payable to the Surviving Spouse hereunder shall be reduced to reflect
the actuarial value of such age difference. The Surviving Spouse's benefit shall
be reduced so that it is the Actuarial Equivalent of the benefit payable to a
Surviving Spouse who is ten years younger than the Participant.

5.8 DETERMINATION OF BENEFITS.

In determining the amount of a retirement or other benefit payable to a
Participant or Surviving Spouse under this Article V, the following provisions
shall apply:

(a)  YEARS OF SERVICE. The Administrator shall have the sole authority to
     determine a Participant's years of service under this Plan. In the case of
     a Participant--
     (1)  who is employed by DePuy during a period when he does not participate
          in the Plan;
     (2)  whose employment relationship with DePuy terminates; and
     (3)  who is subsequently rehired and becomes a Participant in the Plan,

                                       16

<PAGE>
 
     such Participant's years of service shall not include the initial period of
     DePuy employment. Notwithstanding the preceding sentence, the Administrator
     shall have the discretion at any time to retroactively include service for
     such Participant's initial period of employment with DePuy.

(b)  ESTIMATED BENEFITS. Notwithstanding any other provision of this Plan, in
     determining the amount of any benefit payable under this Article V, or any
     individual offset or other component of such a benefit, the Administrator
     shall have the sole discretion to estimate such amount. Such an estimate
     shall be calculated on the basis of the most current and most accurate data
     reasonably available at the time of performing the benefit calculation, as
     determined by the Administrator. The Administrator shall have the sole
     discretion to consider such an estimate as a final calculation, or to
     subsequently modify such benefit, and adjust Plan payments accordingly, if
     and when additional data or information becomes available.

5.9 TRANSFERRED EMPLOYEES FROM BOEHRINGER MANNHEIM CORPORATION.

In the case of a person who becomes a Participant on or after October 1, 1996,
and who was transferred from a position of employment with Boehringer Mannheim
Corporation or one of its subsidiaries or affiliates, the person shall be
treated as a new employee, except as otherwise permitted under section 5.8(a).

5.10 PARTICIPANTS TRANSFERRING TO BOEHRINGER MANNHEIM CORPORATION.

A Participant who transfers from the DePuy Affiliated Group to a position of
employment within the Boehringer Mannheim Corporation controlled group, on or
after October 1, 1996, shall be treated as any other Participant who retires or
otherwise leaves the DePuy Affiliated Group.

                                       17
<PAGE>
 
ARTICLE VI. OTHER TERMINATIONS OF EMPLOYMENT

6.1 TERMINATION BEFORE FIVE OR TEN YEARS OF SERVICE

If a Participant's Employment within the DePuy Affiliated Group terminates for
any reason other than Retirement, death, or Disability before the Participant
completes ten years of service within the DePuy Affiliated Group (five years in
the case of a Participant who entered the Plan before January 1, 1992), the
Participant (and his Surviving Spouse) will not be entitled to any benefits
under the Plan. If a Participant's Employment within the DePuy Affiliated Group
terminates due to death or Disability, and before the Participant completes five
years of service within the DePuy Affiliated Group or attains age 60, the
Participant (and his Surviving Spouse) will not be entitled to any benefits
under the Plan.

6.2 TERMINATION FOR CAUSE

Notwithstanding anything to the contrary contained elsewhere in this Plan, any
Participant whose employment is terminated under circumstances that constitute
Termination for Cause will not be entitled to any benefits under the Plan. This
provision shall apply without regard to the Participant's age or years of
service within the DePuy Affiliated Group at the time of such termination.

                                       18

ARTICLE VII. NONCOMPETITION

7.1 NONCOMPETITION

The Participant's right to receive Benefits provided in this Plan and to have
any Benefits paid to his Surviving Spouse under this Plan are further
conditioned upon the following terms and conditions--

(a)  The Participant will not act, directly or indirectly, as a stockholder,
     officer, director, employee, agent, sole proprietor, partner, or consultant
     of, or otherwise participate in, any enterprise or organization which is
     competitive with the then present business of DePuy or an affiliate within
     the DePuy Affiliated Group, as it is now being conducted or may be

     (1)  the amount held is in excess of ten percent of the outstanding stock
          of that corporation; or
     (2)  the stock has a value representing more than 100 percent of the
          individual's personal net worth.

(b)  The Participant will not knowingly participate, directly or indirectly, in
     the employment, solicitation for employment, or advice or recommendation to
     any person or business entity that he or it employ, or solicit for
     employment, any individual now or hereafter employed in other than an
     hourly paid capacity by DePuy or an affiliate within the DePuy Affiliated
     Group, including any dealer, distributor, or independent contractor acting
     as an agent of DePuy or an affiliate within the DePuy Affiliated Group,
     with respect to the sale or distribution of products sold by DePuy or an
     affiliate within the DePuy Affiliated Group, without the prior express
     written consent of DePuy.

(c)  The Participant will not solicit, contact, or communicate with any
     physician, scientist, or other person who is or has been involved in the

     concerning the development of products reasonably related to the present
     business of DePuy, as it is now being conducted or may be conducted during
     the payment of Benefits under the Plan without the express prior written
     consent of DePuy.

(d)  The Participant will treat as confidential and will not, without prior
     written authorization from DePuy, directly or indirectly disclose to any
     person, firm, association, or corporation, or use for Participant's own
     benefit, any financial statements, information, plans, products,

                                       19

<PAGE>
 
     data, results of tests or surveys, customer or supplier lists, or any other
     trade secrets or confidential material or information regarding DePuy, or
     an affiliate within the DePuy Affiliated Group, including any and all
     information and instructions, technical or otherwise, obtained, compiled,
     prepared, issued, or communicated for the use of DePuy, or an affiliate
     within the DePuy Affiliated Group, or any information concerning the
     present or future products, processes or methods of operation of DePuy or
     an affiliate within the DePuy Affiliated Group, or information concerning
     improvements or inventions or know-how relating to the same or any part
     thereof, it being the intent of DePuy to restrict Participant from
     disseminating or using for Participant's own benefit any information
     belonging directly or indirectly to DePuy or an affiliate within the DePuy
     Affiliated Group, or agents which is not readily available to the general
     public.

(e)  The Participant agrees to return to DePuy or an affiliate within the DePuy
     Affiliated Group all data, drawings, prints, and other written information
     (including all copies thereof) in the Participant's possession or under the
     Participant's control which were prepared by or for the Participant or
     furnished Participant by DePuy or an affiliate within the DePuy Affiliated
     Group, or its employees, agents, or consultants during the term of the
     Participant's employment by DePuy or an affiliate within the DePuy
     Affiliated Group, prior to termination.

(f)  The Participant will not, directly or indirectly, take any action which
     could or would interfere with, damage, or destroy the goodwill and
     reputation of DePuy or an affiliate within the DePuy Affiliated Group, or
     any of its directors, officers, employees, operations, or products.

ARTICLE VIII. MISCELLANEOUS 

8.1 AMENDMENT AND TERMINATION

The CEO or the Board may at any time terminate or amend the Plan in any respect.
However, a termination or amendment of the Plan shall not, without the written
consent of the Participant reduce the amount payable with respect to the
Participant, based on--

(a)  the Participant's DePuy Income at the time the amendment is adopted,

(b)  the Plan provisions in effect at the time the amendment is adopted, and

(c)  the value of offsets for Other Retirement Income as determined when Benefit
     payments under this Plan commence.

8.2 FUNDING

(a)  All benefits paid under the Plan shall be paid from the general assets of
     DePuy, except to the extent paid from any "grantor trust" (under sections
     671 through 677 of the Code) maintained by DePuy or any affiliate within
     the DePuy Affiliated Group, in connection with the Plan. Said trust is
     subject to the claims of creditors of DePuy or any affiliate within the
     DePuy Affiliated Group, in the event of insolvency. This Plan shall not be
     interpreted to provide any Participant or Surviving Spouse with any secured
     interest or right to any assets of DePuy, and no Participant or Surviving
     Spouse shall acquire any interest greater than that of an unsecured
     creditor.

(b)  DePuy shall make contributions to the trust no less often than twice per
     year. The Administrator shall ensure that contributions are calculated
     using the guidance and methodology of Financial Accounting Standards Board
     statement No. 87. The first contribution required hereunder each year, to
     be made no later than July 1 of such year, shall fund the annual cost for
     the Participants on June 30 of such year. The second contribution required
     hereunder will be made no later than December 31 of each year. The second
     contribution shall fund the annual cost for individuals who become
     Participants in this Plan between July 1 and December 31 of such year.
     DePuy may, in its sole discretion, make additional contributions to the
     trust to fund benefits accrued under this Plan.

                                       21
<PAGE>
 
8.3 TAX LIABILITY

DePuy may withhold, or direct the withholding of, from any payment of Benefits
hereunder any taxes required to be withheld and such sum as
DePuy may reasonably estimate to be necessary to cover any taxes for which DePuy
may be liable and which may be assessed with regard to such payment.

8.4 ASSIGNMENT

The Participant (or Surviving Spouse) may not assign, pledge, or otherwise
transfer or encumber any of the Participant's (or Surviving Spouse's) Benefits
except as permitted by agreement of the CEO or the Board.

8.5 SUCCESSORS

The Plan and the rights and obligations of DePuy or any affiliate within the
DePuy Affiliated Group hereunder shall be binding upon, and inure to the
benefits of the Participants and their Surviving Spouses only, and the
successors and assigns of DePuy or any affiliate within the DePuy Affiliated
Group.

8.6 SEVERABILITY

In the event that any one or more of the provisions of this Plan shall be held
to be invalid, illegal, or unenforceable, the validity, legality, or
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

8.7 NONUNIFORM DETERMINATIONS

The determinations of the CEO, the Board, or the Administrator under the Plan
need not be uniform and may be made selectively among Participants (and
Surviving Spouses) who receive, or are eligible to receive, Benefits under the
Plan, whether or not such Participants (or Surviving Spouses) are similarly
situated. Such determinations, however, may not result in payment to a
Participant or Surviving Spouse of an amount that is less than the amount that
is otherwise provided for under the terms of this Plan. The Administrator may,
with the approval of the CEO or the Board, waive the application of specific
provisions of the Plan for individual Participants or Surviving Spouses. Such
waivers may not adversely affect the Participant or Surviving Spouse, and can be
granted only if the waiver will not have a material adverse economic or
competitive impact on the Plan or DePuy or any affiliate within the DePuy
Affiliated Group.

8.8 SEPARATION FROM OTHER PLANS

into account in determining any benefit under any other pension, retirement,
thrift, profit sharing, 401(k), group insurance, or other benefit plan
maintained or hereafter established by DePuy or any affiliate within the DePuy
Affiliated Group.


8.9 EFFECTIVE DATE

This Plan, as initially adopted, was effective January 1, 1985. The Plan as
restated shall be effective as of October 1, 1996.
