and shall not become available for future distribution under the Plan.

4.   ADMINISTRATION AND GRANTS OF OPTIONS UNDER THE PLAN.

     a.   PROCEDURE FOR GRANTS. All grants of Options to Outside Directors under
          this Plan shall be automatic and nondiscretionary and shall be made
          strictly in accordance with the following provisions:

                                                                     Page 2 of 8

<PAGE>   3

          i)   No person shall have any discretion to select which Outside
               Directors shall be granted Options or to determine the number of
               Shares to be covered by Options granted to Outside Directors.

          ii)  Each Outside Director shall be automatically granted an Option to
               purchase 25,000 Shares on the effective date of the Initial
               Public Offering of the Company's common stock or the date on
               which such person first becomes an Outside Director, whether
               through election by the shareholders of the Company or
               appointment by the Board to fill a vacancy; provided, however,
               that an Inside Director who ceases to be an Inside Director but
               who remains a Director shall not receive a First Option.

          iii) Each Outside Director shall be automatically granted an Option to
               purchase 25,000 Shares on the day following the date of the
               Company's annual stock holder's meeting each year, provided he or
               she is then an Outside Director.

          iv)  Notwithstanding the provisions of subsections (ii) and (iii)
               hereof, any exercise of an Option granted before the Company has
               obtained stockholder approval of the Plan in accordance with
               Section 16 hereof shall be conditioned upon obtaining such
               stockholder approval of the Plan in accordance with Section 16
               hereof.

          v)   The terms of each Option granted hereunder shall be as follows:

               (a)  the term of the Option shall be ten (10) years.

               (b)  the exercise price per Share shall be 100% of the Fair
                    Market Value per Share on the date of grant of the Option.
                    In the event that the date of grant of the Option is not a
                    trading day, the exercise price per Share shall be the Fair
                    Market Value on the next trading day immediately following
                    the date of grant of the Option.

               (c)  subject to Section 10 hereof, the Option shall be six (6)
                    months from the date of grant exercisable as to 50% of the
                    Shares subject thereto and shall become exercisable as to
                    the balance of the Shares subject thereto twelve (12) months
                    from the date of grant, provided that the Optionee continues
                    to serve as a Director on such dates.

          vi)  In the event that any Option granted under the Plan would cause
               the number of Shares subject to outstanding Options plus the
               number of Shares previously purchased under Options to exceed the
               Pool, then the remaining Shares available for Option grant shall
               be granted under Options to the Outside Directors on a pro rata
               basis. No further grants shall be made until such time, if any,
               as additional Shares become available for grant under the Plan
               through action of the Board or the stockholders to increase the
               number of Shares which may be issued under the Plan or through
               cancellation or expiration of Options previously granted
               hereunder.

                                                                     Page 3 of 8
<PAGE>   4

5.   ELIGIBILITY. Options may be granted only to Outside Directors. All Options
shall be automatically granted in accordance with the terms set forth in Section
4 hereof.

The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate the Director's relationship with the Company at any time.

6.   TERM OF PLAN. The Plan shall become effective upon the earlier to occur of
its adoption by the Board or its approval by the stockholders of the Company as
described in Section 16 of the Plan. It shall continue in effect for a term of
ten (10) years unless sooner terminated under Section 11 of the Plan.

7.   FORM OF CONSIDERATION. The consideration to be paid for the Shares to be
issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an Option, have been owned by the Optionee for
more than six (6) months on the date of surrender, and (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of the
Shares as to which said Option shall be exercised, (iv) consideration received
by the Company under a cashless exercise program implemented by the Company in
connection with the Plan, or (v) any combination of the foregoing methods of
payment.

8.   EXERCISE OF OPTION.

     a.   PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option granted
          hereunder shall be exercisable at such times as are set forth in
          Section 4 hereof; provided, however, that no Options shall be
          exercisable until stockholder approval of the Plan in accordance with
          Section 16 hereof has been obtained.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed to be exercised when written notice of such
          exercise has been given to the Company in accordance with the terms of
          the Option by the person entitled to exercise the Option and full
          payment for the Shares with respect to which the Option is exercised
          has been received by the Company. Full payment may consist of any
          consideration and method of payment allowable under Section 7 of the
          Plan. Until the issuance (as evidenced by the appropriate entry on the
          books of the Company or of a duly authorized transfer agent of the
          Company) of the stock certificate evidencing such Shares, no right to
          vote or receive dividends or any other rights as a stockholder shall
          exist with respect to the Optioned Stock, notwithstanding the exercise
          of the Option. A share certificate for the number of Shares so
          acquired shall be issued to the Optionee as soon as practicable after
          exercise of the Option. No adjustment shall be made for a dividend or
          other right for which the record date is prior to the date the stock
          certificate is issued, except as provided in Section 10 of the Plan.

                                                                     Page 4 of 8
<PAGE>   5

          Exercise of an Option in any manner shall result in a decrease in the
          number of Shares which thereafter may be available, both for purposes
          of the Plan and for sale under the Option, by the number of Shares as
          to which the Option is exercised.

     b.   TERMINATION OF CONTINUOUS STATUS AS A DIRECTOR. Subject to Section 10
          hereof, in the event an Optionee's status as a Director terminates
          (other than upon the Optionee's death or total and permanent
          disability (as defined in Section 22(e)(3) Of the Code)), the Optionee
          may thereafter exercise his or her Option, but only to the extent that
          the Optionee was entitled to exercise it on the date of such
          termination (but in no event later than the expiration of its ten (10)
          year term). To the extent that the Optionee was not entitled to
          exercise an Option on the date of such termination, and to the extent
          that the Optionee does not exercise such Option (to the extent
          otherwise so entitled) within the time specified herein, the Option
          shall terminate.

     c.   DISABILITY OF OPTIONEE. In the event Optionee's status as a Director
          terminates as a result of total and permanent disability (as defined
          in Section 22(e)(3) of the Code), the Optionee may thereafter exercise
          his or her Option, but only to the extent that the Optionee was
          entitled to exercise it on the date of such termination (but in no
          event later than the expiration of its ten (10) year term). To the
          extent that the Optionee was not entitled to exercise an Option on the
          date of termination, or if he or she does not exercise such Option (to
          the extent otherwise so entitled) within the time specified herein,
          the Option shall terminate.

     d.   DEATH OF OPTIONEE. In the event of an Optionee's death, the Optionee's
          estate or a person who acquired the right to exercise the Option by
          bequest or inheritance may exercise the Option, but only to the extent
          that the Optionee was entitled to exercise it on the date of death
          (but in no event later than the expiration of its ten (10) year term).
          To the extent that the Optionee was not entitled to exercise an Option
          on the date of death, and to the extent that the Optionee's estate or
          a person who acquired the right to exercise such Option does not
          exercise such Option (to the extent otherwise to entitled) within the
          time specified herein, the Option shall terminate.

9.   NON-TRANSFERABILITY OF OPTIONS. The Option may not be sold pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

                                                                     Page 5 of 8

10.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR ASSET
     SALE.

     a.   CHANGES IN CAPITALIZATION. Subject to any required action by the
          stockholders of the Company, the number of Shares covered by each
          Option, the number of Shares which have been authorized for issuance
          under the Plan but as to which no Options have yet been granted or
          which have been returned to the Plan upon cancellation or expiration
          of an Option, as well as the price per Share covered by each such
          outstanding Option, and the number of Shares issuable pursuant to the
          automatic grant provisions of Section 4 hereof shall be
          proportionately adjusted for any increase or decrease in the number of
          issued Shares resulting from a stock split, reverse stock split, stock
          dividend, combination or reclassification of the Common Stock, or any
          other increase or decrease in the number of issued Shares effected
          without receipt of consideration by the Company; provided, however,
          that conversion of any convertible securities of the Company shall not
          be deemed to have been "effected without receipt of consideration."
          Except as expressly provided herein, no issuance by the Company of
          shares of stock of any class, or securities convertible into shares of
          stock of any class, shall affect, and no adjustment by reason thereof
          shall be made with respect to, the number or price of Shares subject
          to an Option.

     b.   DISSOLUTION OR LIQUIDATION. In the event of the proposed dissolution
          or liquidation of the Company, to the extent that an Option has not
          been previously exercised, it shall terminate immediately prior to the
          consummation of such proposed action.

     c.   MERGER OR ASSET SALE. In the event of a merger of the Company with or
          into another corporation or the sale of substantially all of the
          assets of the Company, outstanding Options may be assumed or
          equivalent options may be substituted by the successor corporation or
          a Parent or Subsidiary thereof (the "Successor Corporation"). If an
          Option is assumed or substituted for, the Option or equivalent option
          shall continue to be exercisable as provided in Section 4 hereof for
          so long as the Optionee serves as a Director or a director of the
          Successor Corporation. Following such assumption or substitution, if
          the Optionee's status as a Director or director of the Successor
          Corporation, as applicable, is terminated other than upon a voluntary
          resignation by the Optionee, the Option or option shall become fully
          exercisable, including as to Shares for which it would not otherwise
          be exercisable. Thereafter, the Option or option shall remain
          exercisable in accordance with Section 8(c) through (d) above.

          If the Successor Corporation does not assume an outstanding Option or
          substitute for it an equivalent option, the Option shall become fully
          vested and exercisable, including as to Shares for which it would not
          otherwise be exercisable. In such event the Board shall notify the
          Optionee that the Option shall be fully exercisable for a period of
          thirty (30) days from the date of such notice, and upon the expiration
          of such period the Option shall terminate.

                                                                     Page 6 of 8
<PAGE>   7

          For the purposes of this Section 10(c), an Option shall be considered
          assumed if, following the merger or sale of assets, the Option confers
          the right to purchase or receive, for each Share of Optioned Stock
          subject to the Option immediately prior to the merger or sale of
          assets, the consideration (whether stock, cash, or other securities or
          property) received in the merger or sale of assets by holders of
          Common Stock for each Share held on the effective date of the
          transaction (and if holders were offered a choice of consideration,
          the type of consideration chosen by the holders of a majority of the
          outstanding Shares). If such consideration received in the merger or
          sale of assets is not solely common stock of the successor corporation
          or its Parent, the Board may, with the consent of the successor
          corporation, provide for the consideration to be received upon the
          exercise of the Option, for each Share of Optioned Stock subject to
          the Option, to be solely common stock of the successor corporation or
          its Parent equal in fair market value to the per share consideration
          received by holders of Common Stock in the merger or sale of assets.

11.  AMENDMENT AND TERMINATION OF THE PLAN.

     a.   AMENDMENT AND TERMINATION. The Board may at any time amend, alter,
          suspend, or discontinue the Plan, but no amendment, alteration,
          suspension, or discontinuation shall be made which would impair the
          rights of any Optionee under any grant theretofore made, without his
          or her consent. In addition, to the extent necessary and desirable to
          comply with any applicable law, regulation or stock exchange rule, the
          Company shall obtain stockholder approval of any Plan amendment in
          such a manner and to such a degree as required.

     b.   EFFECT OF AMENDMENT OR TERMINATION. Any such amendment or termination
          of the Plan shall not affect Options already granted and such Options
          shall remain in full force and effect as if this Plan had not been
          amended or terminated.

12.  TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for all
purposes, be the date determined in accordance with Section 4 hereof.

13.  CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued pursuant to
the exercise of an Option unless the exercise of such Option and the issuance
and delivery of such Shares pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act, the rules and regulations promulgated thereunder,
state securities laws, and the requirements of any stock exchange upon which the
Shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

As a condition to the exercise of an Option, the Company may require the person
exercising such Option to represent and warrant at the time of any such exercise
that the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares, if, in the opinion of counsel for
the Company, such a representation is required by any of the aforementioned
relevant provisions of law.

                                                                     Page 7 of 8
<PAGE>   8

Inability of the Company to obtain authority from any regulatory body having
jurisdiction, which authority is deemed by the Company's counsel to be necessary
to the lawful issuance and sale of any Shares hereunder, shall relieve the
Company of any liability in respect of the failure to issue or sell such Shares
as to which such requisite authority shall not have been obtained.

14.  RESERVATION OF SHARES. The Company, during the term of this Plan, will at
all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

15.  OPTION AGREEMENT. Options shall be evidenced by written option agreements
in such form as the Board shall approve.

16.  STOCKHOLDER APPROVAL. Continuance of the Plan shall be subject to approval
by the stockholders of the Company at or prior to the first annual meeting of
stockholders held subsequent to the granting of an Option hereunder. Such
stockholder approval shall be obtained in the degree and manner required under
applicable state and federal law and any stock exchange rules.

                                                                     Page 8 of 8<PAGE>   1
                                                                    Exhibit 10.1

              EXECUTIVE INCENTIVE COMPENSATION DEFERRED BONUS PLAN
                    AS AMENDED AND RESTATED DECEMBER 9, 1999

         This Executive Incentive Compensation Deferred Bonus Plan (the "Plan")
is established by HADCO Corporation to provide incentive to key executives who
contribute to the profits of the corporation by their ability, industry, loyalty
or exceptional service, through making them participants in its success.

         SECTION 1: ELIGIBILITY TO PARTICIPATE. Participants in this Plan shall
be active employees of HADCO Corporation (the "Corporation") or its subsidiaries
or affiliates who are employed in an executive or managerial capacity and who
are designated to receive incentive compensation awards under the Corporation's
executive incentive compensation program, as determined by the Compensation
Committee of the Board of Directors of the Corporation (the "Committee").

         SECTION 2: DETERMINATION AND PARTIAL DEFERRAL OF INCENTIVE
COMPENSATION. The Committee shall determine for each fiscal year of the
Corporation the amount of incentive compensation to be awarded to each of the
Corporation's designated key executives, in accordance with criteria established
by the Committee and approved by the Board of Directors as part of the
Corporation's executive incentive compensation program.

         Payment of sixty percent (60%) of the amount of incentive compensation
awarded to each designated key executive for each year shall be made in a lump
sum in cash (subject to applicable tax withholdings and deductions) as soon as
practicable after the date the award is declared. Payment of the remaining forty
percent (40%) of such incentive compensation award (referred to herein as the
"deferred bonus amount") shall be made (a) in the case of awards made through
calendar year 1997, in cash (subject to applicable tax withholdings and
deductions) in three equal installments over a period of three years commencing
on the one year anniversary date of the award, subject to and in accordance with
the provisions of this Plan, and (b) in the case of awards made in calendar year
1998 or thereafter, in shares of restricted stock (as further described in
Section 6 hereof) of the Corporation valued in accordance with and subject to
all the terms and conditions of the Hadco Corporation 1998 Stock Plan, as
Amended and Restated March 3, 1999 and as amended from time to time (the "1998
Plan").

         SECTION 3: NOTIFICATION AND DESIGNATION OF BENEFICIARIES. Each
designated key executive who is awarded incentive compensation under HADCO
Corporation's executive incentive compensation program for any year shall be
notified by the Corporation of such award and of his participation in this Plan
for such year. Each participant shall file with the Corporation a written
designation of beneficiary or beneficiaries to receive any amounts payable with
respect to the participant in the event of his death, which designation may be
changed from time to time by the filing of a written designation naming a new
beneficiary or beneficiaries. If a participant
<PAGE>   2
dies without designating a beneficiary, or if the designated beneficiary is not
then in existence, any amounts payable with respect to the participant shall be
paid to the participant's estate.

         SECTION 4: ACCOUNTS FOR DEFERRED BONUSES TO BE PAID IN CASH.

         4.1 For all deferred bonuses which are to be paid to the participant in
cash, as provided in Section 2 hereof, the Corporation shall maintain an account
(the "Cash Account") for each participant in this Plan, which shall be credited
with the participant's cash deferred bonus amount and the amount of any deemed
interest pursuant to subsection 4.2 and debited for any distributions to the
participant pursuant to Section 5. No money shall actually be allocated to any
account, as such accounts shall be of a memorandum nature maintained by the
Corporation for accounting purposes and shall not be representative of any
identifiable assets.

         4.2 The undistributed portion of each Cash Account shall be deemed to
earn interest in arrears annually at in interest rate one point above the prime
rate as published in the Wall Street Journal for the last business day of the
previous fiscal year. Interest shall be determined from the last day of the
fiscal year for which the incentive compensation award was made to the close of
the next fiscal year of the Corporation or, if earlier, to the close of the
fiscal year immediately preceding the date of distribution of all or part of a
participant's Cash Account (except as provided in subsection 5.3 in the event of
a distribution on account of involuntary termination of employment or retirement
or in the event of distribution in connection with a Change of Control as
provided in subsection 5.4 hereof). Interest shall be credited to each
participant's Cash Account annually.

         4.3 The Corporation shall furnish to each participant a statement of
amounts credited to or debited from his Cash Account during each fiscal year,
within ninety (90) days after the end of the calendar year in which such fiscal
year ends.

         SECTION 5: DISTRIBUTIONS FROM CASH ACCOUNTS.

         5.1 Each installment of a cash deferred bonus amount to be paid to a
participant shall be made on or about the anniversary date of the original
declaration of the award, commencing on the first such anniversary; provided,
however, that the participant remains employed by the Corporation or any
subsidiary or affiliate as of the date payment is due. Each installment payment
shall include interest on that portion of the bonus to be then distributed,
calculated in accordance with subsection 4.2.

         5.2 If a participant voluntarily terminates his employment with the
Corporation without the prior consent of the chief executive officer of the
Corporation, other than by reason of his retirement at or after the normal
retirement date as described in the HADCO Corporation Retirement Plan or if a
participant's employment is terminated by the Corporation for cause as defined
herein, he shall forfeit any remaining unpaid installments of his deferred bonus
amount and all deemed interest, if any, credited to his account. If the
participant is the chief executive officer of the Corporation, such forfeiture
shall occur if he voluntarily terminates his employment with the Corporation
without the prior consent of the Board of Directors of the Corporation, other
than by reason of his retirement at or after the normal retirement date as
described in the

                                       2
<PAGE>   3
HADCO Corporation Retirement Plan. For purposes of this Plan, employment shall
not be deemed terminated if the participant remains employed by the Corporation
or any subsidiary or affiliate thereof. For purposes of this Agreement, the
Corporation shall have "cause" to terminate the Executive in the event of: (a)
the willful and continued failure by the Executive to substantially perform
his/her duties, after demand for substantial performance is delivered by the
Corporation to the Executive identifying with specificity the grounds for the
Corporation's belief that the Executive has not substantially performed his/her
duties; (b) the permanent physical or mental incapacity of the Executive; (c)
the commission by the Executive of any act of fraud or embezzlement relating to
the property of the Corporation and/or the services to be provided by the
Executive; or (d) the Executive's unauthorized disclosure of proprietary
confidential information of the Corporation or the Executive's engaging in
competition with the Corporation.

         5.3 If a participant is involuntarily terminated from employment
without cause, including by reason of his death or disability or if termination
of employment of a participant is due to retirement at or after the normal
retirement date as described in the HADCO Corporation Retirement Plan, the
balance of the participant's cash deferred bonus amount plus interest determined
to the date of such involuntary termination or retirement, as the case may be,
shall be paid to the participant or his designated beneficiary or beneficiaries
as soon as practicable after the event giving rise to the termination. For
purposes hereof, the definition of "disability" as set forth in the HADCO
Corporation Retirement Plan shall apply.

         5.4 Upon any sale of all or substantially all of the assets of the
Corporation, or upon a merger, consolidation or tender offer in respect of which
the stockholders holding all of the Corporation's outstanding voting securities
immediately prior to the consummation thereof hold less than 50% of all of the
Corporation's outstanding voting securities immediately after such consummation
(each of the foregoing sale, merger, consolidation or tender offer hereinafter
called an "Acquisition"), then the date upon which the full balance of the
participant's cash deferred bonus amount under this Plan will be fully vested
and due and payable shall be automatically accelerated to occur immediately
prior to the consummation of such Acquisition.

         SECTION 6: RESTRICTED STOCK

         6.1 To the extent that the deferred bonus amount is to be paid to a
participant in restricted stock ("Restricted Stock"), as provided in Section 2
hereof, the number of shares of stock to be awarded to the participant shall be
determined by dividing the dollar equivalent of the deferred bonus amount by the
fair market value of the Corporation's common stock, as determined in accordance
with the 1998 Plan, on the day the incentive compensation award is declared. If
any fractional share of stock is calculated to be due a participant, then the
number of shares of Restricted Stock shall be rounded up to the nearest whole
share and the participant's incentive compensation award shall be deemed
adjusted accordingly.

         6.2 All Restricted Stock to be issued to a participant under this Plan
shall be issued under all the terms and conditions of the 1998 Plan.

                                       3
<PAGE>   4
         6.3 If, for any reason, including without limitation restrictions
imposed by the securities laws or any stock exchange, the Corporation deems it
impractical or imprudent, in its sole judgment, to issue shares of Restricted
Stock to a participant, then the deferred bonus amount due the participant in
Restricted Stock shall be replaced by a cash deferred bonus amount with all of
the attributes of, and the same distribution schedule as, the cash deferred
bonus amount described elsewhere in this Plan.

         SECTION 7: MISCELLANEOUS PROVISIONS RELATING TO PAYMENTS.

         7.1 No participant shall have any option or right to choose the amounts
or dates of payment of distributions payable to him under this Plan.

         7.2 All payments under this Plan shall be made from the general assets
of the Corporation and no assets shall be segregated or placed in trust for the
purpose of funding such payments. Participants under this plan shall have the
status of general unsecured creditors of the Corporation.

         7.3 No participant or beneficiary shall have the right to alienate,
anticipate, pledge, encumber or assign any of the payments which he may expect
to receive, contingently or otherwise, under this Plan, and no payments or
rights of any participant or beneficiary shall be subject to attachment,
garnishment or their legal or equitable process available to any creditor.

         7.4 The Corporation shall have the right to accelerate the payment of
any cash distribution payable under this Plan.

         7.5 The Corporation shall have the right to withhold from any
distribution under this Plan the amount of any federal, state or local
withholding taxes due with respect to such distribution, as well as the
employee's share of any payroll taxes relating thereto. Without limiting the
generality of the foregoing, the Corporation may condition the release of cash
deferred bonus amounts upon the participant's making arrangements satisfactory
to the Corporation for payment of withholding taxes due in connection with the
payment of the cash deferred bonus amount.

         SECTION 8: ADMINISTRATION OF PLAN. All determinations, decisions and
directions made or given by the Board of Directors or the Committee under or
with respect to this Plan shall be final and conclusive. The determination of
the Board of Directors or the Committee on any question concerning or involving
the interpretation and administration of this Plan shall be final and
conclusive, and nothing in the Plan shall be deemed to give any officer or
employee of the Corporation, his legal representatives or assigns, any right to
participate in the Corporation's executive incentive compensation program or
this Plan except to the extent, if any, that the Committee may have determined
or approved. The Board of Directors, in passing on the matters which it is
required to approve, may in its discretion rely upon the recommendations made by
the Committee with respect thereto.

                                       4
<PAGE>   5
         SECTION 9: AMENDMENT OR TERMINATION. The Board of Directors may, from
time to time, amend, suspend, or terminate, in whole or in part, any or all of
the provisions of the Plan; provided, however, that no amendment, suspension or
termination shall reduce the right of any participant to receive distributions
of amounts awarded to him prior to the effective date of such amendment,
suspension or termination. Notice of any amendment, suspension or termination of
the Plan shall be given to each participant who is affected thereby. This Plan
may also be terminated in the event of the bankruptcy, insolvency,
reorganization or winding up of the affairs of the Corporation.

         SECTION 10: GENERAL.

         10.1 This Plan shall be governed by and interpreted under the laws of
the Commonwealth of Massachusetts.

         10.2 This Plan shall not be interpreted to constitute a contract of
employment and nothing herein shall give any participant or employee the right
to remain in the employ of the Corporation or its subsidiaries or affiliates, or
interfere with the Corporation's right to terminate his employment at any time.

         10.3 The Committee shall have the authority to interpret this Plan and
to prescribe and rescind rules and regulations relating to it. The
interpretation and construction by the Committee of any provisions of this Plan
or of any right related to an incentive compensation award granted under this
Plan shall be final unless otherwise determined by the Board of Directors of the
Corporation. No member of the Board of Directors or of the Committee shall be
liable, in respect to this Plan, for any act, whether of commission or omission,
taken by any other member or by any officer, agent or employee of the
Corporation or its subsidiaries or affiliates nor, except in circumstances
involving his own bad faith, for anything done or omitted to be done by him.

         10.4 It is intended that cash distributions under this Plan will be
taxable income to the participants in the calendar year in which they are made.
However, neither the Corporation, the Committee nor any employee, officer or
agent thereof guarantees that any particular federal, state or local tax
consequences will occur as a result of participation in this Plan and each
participant shall be responsible for the tax consequences to him of
participating in this Plan. Notwithstanding the preceding sentence, if the
Internal Revenue Service shall at any time interpret this Plan to be ineffective
with regard to the deferral of a participant's income, and that interpretation
becomes final and unappealable, then the Corporation shall distribute to the
participant from the unpaid portion of his cash deferred bonus amount an amount
equal to such income tax liability (but not more than the remaining unpaid
portion of his cash deferred bonus amount). Any remaining portion of the cash
deferred bonus amount shall continue to be subject to the remaining provisions
of this Plan.

         SECTION 11: EFFECTIVE DATE. This Plan shall be effective commencing
with incentive compensation awards made with respect to the Corporation's fiscal
year ending October 26, 1996 and shall continue for each fiscal year thereafter
until terminated as provided herein.
