                  "Company"        The company in respect of whose shares new
                                   rights have been granted;

2.       SHARE CAPITAL

AVAILABILITY OF AUTHORISED SHARE CAPITAL AND PLAN SHARES

(a)      The Company shall at all times keep available sufficient authorised and
         unissued Plan Shares or shall procure that sufficient Plan Shares are
         available for transfer to satisfy the exercise to the full extent still
         possible of all Options which have neither lapsed nor been fully
         exercised taking account of any other obligations of the Company to
         provide shares of the same class as Plan Shares.

VARIATION OF SHARE CAPITAL AND ADJUSTMENT OF OPTIONS

(b)      In the event of any capitalisation issue or rights issue, rights offer
         or any reduction, sub- division, consolidation or other variation of
         the share capital of the Company, the number of Plan Shares comprised
         in any Option and the Option Price may be adjusted by the Company
         (including retrospective adjustments where appropriate) in such manner
         as the Company considers to be in its opinion fair and reasonable
         provided always that no adjustment shall have effect after the date of
         adjustment for so long as the Plan is approved by the Board of Inland
         Revenue, until the Board of Inland Revenue has approved the adjustment.
         Except in the case of an Option over Plan Shares already in issue, no
         adjustment shall be made which would cause the Option Price to be less
         than the nominal value of that Plan Share. Notice of any such
         adjustment shall be given to the Option-holders affected by such
         adjustment by the Committee, who may call in Option certificates for
         endorsement, cancellation or re-issue subsequent upon such adjustment.

(c)      Where an Option subsists over both issued and unissued Plan Shares, the
         adjustment permitted by Rule 2(b) may only be made if the reduction of
         the Option Price of both issued and unissued Plan Shares may be made to
         the same extent.

3.       APPLICATIONS FOR OPTIONS

(a)      Subject to the restrictions hereinafter contained, the Committee may,
         in its absolute discretion, from time to time, announce its intention

         Employee may, not later than the date specified in the Invitation
         referred to in Rule 3(a) as the last date for receipt of applications,

         any such Invitation, by delivery of a Valid Application complying with
         the requirements of this Rule to the secretary for the time being of
         the Company, or as specified on the application form.

TIMING OF GRANT

(b)      No Option shall be granted to any Eligible Employee if such grant shall
         be prohibited under the legislation from time to time in force
         governing the approval of savings-related share option plans involving
         a certified contractual savings scheme.

GRANT OF OPTIONS

(c)      The grant of an Option shall be conditional upon the Eligible Employee
         having submitted to the Committee (or such other party as the Committee
         in its discretion shall direct) a Valid Application, prior to the grant
         of that Option, for entry into a Savings Contract. In making his
         application the Eligible Employee shall state inter alia the monthly
         contribution which he would like to make under the Savings Contract
         and, if he may elect for a 3 year or a 5 year Savings Contract, his
         election in that respect, and if he has elected for a 5 year Savings
         Contract whether he elects for the repayment under the Savings Contract
         to be taken as including the Standard Bonus or the Maximum Bonus (if so
         permitted pursuant to Rule 3(a)). Each such application shall be deemed
         to be in respect of the largest whole number of Plan Shares which can
         be purchased with the expected repayment (including the Standard Bonus
         or Maximum Bonus applied for if this is to be included in accordance
         with Rule 3(a)(v)) under the Savings Contract at the Bonus Date.

(d)      As soon as possible after the final date for the receipt of
         applications in relation to each grant of Options and within 30 days of
         the earliest of the dates on which the Market Value was taken for the
         purposes of determining the Option Price, the Company shall, subject to
         Rule 4(f), grant to each Eligible Employee who has submitted a Valid
         Application an Option in respect of the whole number of Plan Shares for
         which he is deemed to have applied in accordance with Rule 3(c).

(e)      If the Committee receives Valid Applications such that on the grant of
         all the Options applied for the maximum number of Shares determined by
         the Committee pursuant to Rule 3(a)(i) would be exceeded, then subject
         to the provisions of Rule 4(a)(i) the following steps or such other
         arrangements approved in advance by the Inland Revenue shall be carried
         out in the following order to the extent necessary to eliminate the
         excess:

         (i)      if the Maximum Bonus is included, then only the Standard Bonus
                  shall be taken to be included;

         (ii)     the excess over (pound)50, or such greater or lesser amount as
                  the Committee may decide, of the monthly savings contribution
                  chosen by each applicant shall be reduced pro rata to the
                  extent necessary;

         (iii)    the excess over (pound)5 of the monthly savings contribution
                  chosen by each applicant shall be reduced pro-rata to the
                  extent necessary;

                                       15
<PAGE>

         (iv)     if the Standard Bonus is included or is taken to be included
                  then no Bonus shall be taken to be included;

         (v)      applications will be selected by lot, each based on a monthly
                  savings contribution of (pound)5 and the exclusion of any
                  Bonus in the repayment under the Savings Contract.

         As soon as possible after the final date for the receipt of
         applications in relation to each grant of Options and within 42 days of
         the earliest of the dates on which the Market Value was taken for the
         purposes of determining the Option Price, the Company shall grant to
         each Eligible Employee who has submitted a Valid Application, or where
         appropriate to those Eligible Employees selected by lot pursuant to
         this Rule 4(e), an Option in respect of the number of Plan Shares for
         which he is deemed to have applied scaled down proportionately to the
         reduction made in his monthly contributions pursuant to this Rule 4(e).

OPTION CERTIFICATES

(f)      Subject to the Eligible Employee entering into a Savings Contract, as
         soon as possible after the Date of Grant each Eligible Employee shall
         be issued an Option Certificate in respect of his Option, specifying
         the Date of Grant, the number of Plan Shares subject to the Option, the
         Option Price and the Acquisition Price.

OPTIONS ONLY TO BE GRANTED TO EMPLOYEES AND DIRECTORS

(g)      No Option shall be granted to any person who is no longer a director or
         employee of a Group Company on the date Options are granted under this
         Rule 4.

LIFE OF THE PLAN

(h)      No Option may be granted more than ten years after the Adoption Date.

5        NON-TRANSFERABILITY OF OPTIONS

Save as provided in Rule 6(b) no Option nor any right thereunder shall be
capable of being transferred, assigned, charged or otherwise disposed of. Any
such purported transfer, assignment, charge or disposal shall result in the
cancellation of the Option.

               Rights Act 1996; or

         (ii)  of retirement on reaching the Specified Age or his Normal
               Retirement Date; or

         (iii) that his office or employment is in a company of which the
               Company ceases to have Control; or

         (iv)  that his office or employment relates to a business or part of a
               business which is transferred to a person who is not a company of
               which the Company has Control

         he may exercise all or any of his Options in whole or in part during
         the period ending six months after the date of such cessation (at the
         end of which period his Options will lapse to the extent unexercised).

(d)      No person shall be treated for the purposes of Rule 6(c) and 6(g) as
         ceasing to hold the office or employment by virtue of which he is an
         Eligible Employee until he ceases to

                                       17

<PAGE>

         hold any office or employment in the Company or any Associated Company
         over which the Company has Control.

REACHING SPECIFIED AGE

(e)      If at the date of reaching the Specified Age an Option-holder does not
         retire he may exercise his Option within the period of six months
         commencing with that date.

EMPLOYEE TRANSFERRED TO OTHER MEMBER OF THE GROUP

(f)      An Option-holder who is employed on the Bonus Date by an Associated
         Company of a Group Company or by a company of which the Company has
         Control may exercise his Option within the period of six months
         commencing with the Bonus Date.

CESSATION OF EMPLOYMENT IN OTHER CIRCUMSTANCES

(g)      If an Option-holder shall cease to hold the office or employment by
         virtue of which he is an Eligible Employee more than three years after
         the Date of Grant of an Option other than by reason of misconduct, such
         Option may be exercised within six months after the date of such
         cessation at the end of which period his Options will lapse to the
         extent unexercised.

TERMINATION OF SAVINGS CONTRACT

(h)      If an Option-holder gives, or under the terms of the Savings Contract
         has or is deemed to have given, notice to the relevant Savings
         Authority that he intends to stop paying contributions under his
         Savings Contract then, unless the relevant Option is then exercisable
         under this Rule 6, it shall thereupon lapse.

BANKRUPTCY

         (i)   If the Option-holder is adjudicated bankrupt, his Option shall
               thereupon lapse.

CONDITIONS TO BE SATISFIED AT TIME OF EXERCISE

(j)      No Option may be exercised by an Option-holder, or by the legal

               unless the Option is to be exercised pursuant to Rules 6(b), 6(c)
               6(f) and 6(g); or

                                       18

<PAGE>

         (ii)  precluded from such exercise by paragraph 8 of Schedule 9.

EXERCISE TO BE LIMITED TO REPAYMENT PROCEEDS

(k)      If an Option becomes exercisable under any provision of this Plan then
         the maximum number of Plan Shares over which it shall be exercisable
         shall be limited to the largest whole number of Plan Shares that may be
         acquired at the Option Price out of the repayment including any
         interest or Bonus received under the relevant Savings Contract. For
         these purposes the repayment under the Savings Contract shall exclude
         the repayment of any contribution the due date for payment of which
         falls more than one month after the date on which repayment is made.

 7       LOSS OF OFFICE OR EMPLOYMENT

(a)      The grant of an Option does not form part of the Option-holder's
         entitlement to remuneration or benefits pursuant to his contract of
         employment nor does the existence of a contract of employment between
         an Eligible Employee and any company give such Eligible Employee any
         right or entitlement to have an Option granted to him in respect of any
         number of Plan Shares or any expectation that an Option might be
         granted to him whether subject to any conditions or at all.

(b)      The rights and obligations of an Option-holder under the terms and
         conditions of his office or employment shall not be affected by his
         participation in the Plan or any right he may have to participate in
         the Plan.

(c)      An individual who participates in the Plan waives all and any rights to
         compensation or damages in consequence of the termination of his office
         or employment with any company for any reason whatsoever in so far as
         those rights arise, or may arise, from his ceasing to have rights under
         or be entitled to exercise any Option under the Plan as a result of
         such termination or from the loss or diminution of value of such rights
         or entitlements. By participating in this Plan the Option-holder agrees
         that, if necessary, his terms of employment shall be varied
         accordingly.

 8       TAKEOVERS, RECONSTRUCTION, AMALGAMATION & LIQUIDATION

CHANGE IN CONTROL OF THE COMPANY - ACQUIRING COMPANY

(a)      If after the Adoption Date and subject to Rules 8(f) to 8(j), any
         company has become an Acquiring Company the Committee shall as soon as
         practicable thereafter notify every Option-holder accordingly, and each
         Option-holder may within the Appropriate Period:

                                       19

<PAGE>

         (i)   exercise all or any of his Options to the extent of the repayment
               due under the relevant Savings Contracts; or

         (ii)  to the extent that an Option is not or has not been exercised,
               execute, with the consent of the Acquiring Company, an Option
               Rollover by a notice in writing in a form prescribed by the
               directors of the Acquiring Company.

(b)      To the extent that any Option which has become exercisable and/or
         capable of being Rolled-over pursuant to Rule 8(a)(i) or 8(a)(ii) has
         not been exercised and/or Rolled-over at the expiry of the Appropriate
         Period it shall to the extent unexercised lapse.

(c)      For the purposes of an Option Rollover the new rights shall only be
         regarded as equivalent to the old rights if:

         (i)   the shares to which they relate satisfy the conditions of
               paragraph 10 to 14 of Schedule 9; and

         (ii)  the new rights are exercisable in the same manner as the old
               rights and subject to the provisions of this Plan as it had
               effect immediately before an Option Rollover; and

         (iii) the total market value of the Plan Shares subject to an Option
               which is being Rolled-over is equal immediately before such
               Option Rollover to the total market value (in each case
               determined in accordance with Part VIII of the Taxation of
               Chargeable Gains Act 1992) of the shares in respect of which an
               Option-holder's new rights are being granted immediately after
               such Option Rollover; and

         (iv)  the total amount payable in respect of the exercise in full of an
               Option following an Option Rollover is equal to the total
               Acquisition Price immediately preceding such Option Rollover.

(d)      For the purposes of any application of the provisions of this Plan,
         following an Option Rollover any new rights granted pursuant to Rule
         8(a) shall be regarded as having been granted at the time the
         corresponding old rights were granted. With effect from the Option
         Rollover, the new rights shall be subject to the provisions of the Plan
         as it had effect in relation to Options which have been released.

CHANGE IN CONTROL OF THE COMPANY - ACQUIRING PERSON

(e)      If after the Adoption Date, a person becomes an Acquiring Person and
         subject to Rules 8(f) to 8(j) the Committee shall, as soon as
         practicable thereafter, notify every Option-

                                       20

<PAGE>

         holder accordingly and each Option-holder may within the Appropriate
         Period exercise his Options to the extent of the repayment due under
         the relevant Savings Contracts (but in the case of a Compromise subject
         to Rules 8(f) to 8(j)) and any Option which has become exercisable
         pursuant to this Rule 8(e) and has not been exercised at the expiry of
         the Appropriate Period shall to the extent unexercised lapse.

CHANGE IN CONTROL OF THE COMPANY - ADDITIONAL PROVISIONS FOR COMPROMISES

(f)      Where a Compromise is proposed between the Company and its members:

         (i)   Options which prior to the date of any general meeting of the
               members ordered by the court have become exercisable pursuant to
               the Rules of this Plan excluding Rule 8(g) shall, subject to
               Rules 8(h) to 8(j) remain exercisable and may be exercised in
               accordance with Rule 8(a) or (e) or at the election of the
               Option-holder be exercised on the basis set out in Rule 8(g); and

         (ii)  Rule 8(g) shall apply to any Option not falling within Rule
               8(f)(i).

(g)      Options to which this Rule 8(g) applies shall become exercisable from
         the date of the meeting of the members ordered by the court on terms
         that exercise is conditional on the court sanctioning the Compromise
         and where exercise is permitted under this Rule 8(g):

         (i)   notice of exercise shall be in such form as may be prescribed by
               the Committee; and

         (ii)  notwithstanding any other provision in this Plan, the date of
               exercise of all Options exercised conditionally pursuant to this
               Rule 8(g) shall be the date on which the court sanctions the
               Compromise.

(h)      Notwithstanding any other Rule in this Plan, unless the Committee
         determines otherwise, no notice of exercise of an Option shall be
         effective if received on or after the day on which it is anticipated
         that the court will sanction the Compromise.

(i)      If after six months from the date of the meeting ordered by the court
         to consider the Compromise referred to in Rule 8(f) the court has not
         sanctioned the Compromise, the conditional exercise of Options under
         Rule 8(g) shall be of no effect and Rules 8(f) and 8(h) shall cease to
         apply in relation to that Compromise.

(j)      Upon the Compromise becoming effective, any Options, to the extent
         unexercised, shall lapse.

PLAN SHARES CEASING TO SATISFY PARAGRAPHS 10 TO 14 OF SCHEDULE 9

(k)      If a resolution is proposed or an action taken as a result of which
         Plan Shares will cease to satisfy the requirements of any of paragraphs
         10 to 14 of Schedule 9, then, unless the Committee determines that all
         Options may be exercised in such manner as it may determine at such
         time as it may specify but in any event before the date on which Plan
         Shares will cease to satisfy the requirements of paragraphs 10 to 14 of
         Schedule 9, the Committee will be deemed to have notified the Board of
         Inland Revenue that the Plan no longer satisfies the requirements for
         approval and that from then on the Plan shall continue in force as an
         unapproved plan. From the date of such resolution being passed or such
         action being taken the definition of Plan Shares in Rule 1(a) shall be
         taken to have been amended to exclude the words "which satisfy the
         conditions specified in paragraphs 10 to 14 inclusive of Schedule 9"
         and requirements throughout the Plan to obtain the approval of the
         Board of Inland Revenue shall no longer have effect. The Committee
         shall notify Option-holders in writing that Options may be exercised or
         that the status of the Plan will be changed and shall send a copy of
         that notification to the Board of Inland Revenue.

LIQUIDATION

(l)      If notice is duly given of a general meeting at which a resolution will
         be proposed for the voluntary winding-up of the Company, except for the
         purposes of reconstruction or amalgamation, an Option shall be
         exercisable in whole or in part at any time thereafter until the
         resolution is duly passed or defeated or the general meeting concluded
         or adjourned sine die, whichever shall first occur. If such a
         resolution is passed, the Option shall, to the extent unexercised,
         thereupon lapse and if such a resolution is defeated the relevant
         Option shall, to the extent unexercised, thereupon continue to subsist.

9        EXERCISE OF OPTIONS

PROCEDURES ON EXERCISE

(a)      Exercise of an Option, or of new rights under this Plan, shall be
         effected by a notice in writing in a form prescribed from time to time
         by the Committee lodged with the Secretary of the company or at its
         office as appropriate or with the Company's duly appointed agent
         specifying the number of Plan Shares in respect of which the Option is
         being exercised and accompanied by evidence of the termination of the
         related Savings Contract. The exercise of the Option will not take
         place until a remittance for the Acquisition Price for the Plan Shares
         concerned is received. Payment may be made by banker's draft or cheque
         or telegraphic or other electronic transfer provided that if a cheque
         is not cleared the Eligible Employee shall be deemed never to have
         exercised his Option and neither the Company nor any other person will
         be under any obligation to

                                       22

<PAGE>

         provide any Plan Shares for him. Notwithstanding anything to the
         contrary therein contained such notice shall (other than in the
         circumstances contained in the immediately preceding proviso and/or
         Rule 8(g) above) take effect upon receipt of notice and payment in full
         and such day shall, notwithstanding Rule 11(c) constitute for all
         purposes the date of exercise of such Option and the Secretary of the
         Company shall procure that the said shares are issued or transferred
         within 28 days thereafter. The Option Certificate should also be lodged
         but failure to do so will not invalidate the exercise of the Option.
         The company will keep a suitable form of notice available, so that an
         Option-holder desirous of exercising an Option may obtain copies
         thereof from the Secretary of the Company.

(b)      All transfers and all allotments of Plan Shares shall be subject to any
         necessary consents of HM Treasury or other authorities in the United
         Kingdom or elsewhere under enactment's or regulations for the time
         being in force and it shall be the responsibility of the Option-holder
         to comply with any requirements to be fulfilled in order to obtain or
         obviate the necessity for any such consent.

RIGHTS ATTACHING TO PLAN SHARES

(c)      Plan Shares transferred pursuant to this Plan will be transferred
         without the benefit of any rights attaching thereto by reference to a
         record date preceding the date of exercise. Save as regards rights
         attaching to Plan Shares by reference to a record date prior to the
         date on which the Plan Shares are allotted and issued, Plan Shares
         issued upon the exercise of Options shall be identical and rank pari
         passu in all respects with shares of the same class then in issue.

 10      PLAN AMENDMENTS AND TERMINATION

AMENDMENTS

(a)      Notwithstanding the provisions of Rules 10(b) to 10(d) and 11(b), the
         Committee may at any time make such alterations (including additions)
         to the Rules as are necessary to secure that the Rules receive initial
         approval from the Board of Inland Revenue under Schedule 9 and continue
         to be so approved.

(b)      Subject to Rules 10(c) and 10(d) the Committee may from time to time at
         its absolute discretion, amend any of the Rules.

(c)      No amendment waiver or replacement to or of this Plan (or any Rule)
         shall be made to the extent to which it would have the effect of
         abrogating or altering adversely any of the subsisting rights of
         Option-holders except with such consent on their part as would be
         required by the provisions of the Company's Bye-Laws if the Plan Shares
         to be issued or transferred on the exercise of the Options already
         granted and still subsisting were so

                                       23

<PAGE>

         issued or transferred and constituted a separate class of share capital
         and if such provisions applied mutatis mutandis thereto.

(d)      So long as this Plan remains approved under Schedule 9 no amendment to
         this Plan shall take effect after the date of alteration until the
         Board of Inland Revenue has approved the amendment or the Committee is
         deemed to have given the notification to the Inland Revenue described
         in Rule 8(k).

(e)      The Committee shall have the power from time to time to make or vary
         regulations for the administration of this Plan and to amend the terms
         or impose further conditions on the grant and exercise of Options to
         take account of overseas taxation, and securities or exchange control
         laws provided always that such regulations, terms and conditions shall
         not be inconsistent with the provisions of this Plan and shall not
         cause any of the provisions of Schedule 9 relevant to this Plan to
         cease to be satisfied.

TERMINATION

(f)      Notwithstanding the provision contained in Rule 4(h), the Board of
         Directors or the Committee may at any time resolve that no further
         Options be granted under this Plan, and in such event no further
         Options will be granted but in all other respects the provisions of
         this Plan shall remain in full force and effect.

 11      ADMINISTRATION

         relevant notices and other documents sent by the Company to its
         ordinary shareholders generally.

         be given to those Option-holders affected by such amendment.

         Company to be appropriate. Notices sent by post shall be deemed to have
         been given on the fifth day following the date of posting.

                       TYCO EMPLOYEE STOCK PURCHASE PLAN

                                    ARTICLE 1

                                     PURPOSE

The Tyco Employee Stock Purchase Plan (the "Plan") is created for the purpose of
encouraging stock ownership by officers and employees of Tyco International Ltd.
and its subsidiaries (the "Company") so that they may share in growth of the
Company by acquiring or increasing their proprietary interest in the Company.

                                    ARTICLE 2

                           ADMINISTRATION OF THE PLAN

The Plan may be administered by a committee appointed by the Board of Directors
of the Company (the "Committee"). The Board of Directors shall determine the
number of members of the Committee and, from time to time, may add or remove
members from the Committee. The Committee may select one of its members as
Chairperson and may hold meetings at such times and places as it may determine.
Acts by a majority of the Committee, or acts approved by a majority of the
Committee, shall be valid acts of the Committee.

The interpretation and construction by the Committee of any provision of the
Plan shall be final unless otherwise determined by the Board of Directors. The
Committee may adopt, from time to time, such rules and regulations, as it deems
appropriate for carrying out the Plan. No member of the Board of Directors or
the Committee shall be liable for any action or determination made in good faith
with respect to the Plan.

In the event the Board of Directors fails to appoint or refrains from appointing
a Committee, the Board of Directors shall have the power and authority to
administer the Plan. In such event, the term "Committee" wherever used herein
shall be deemed to mean the Board of Directors.

                                    ARTICLE 3

                               ELIGIBLE EMPLOYEES

The Company will, from time to time, determine which of its employees (including
employees of its subsidiaries and divisions) will be eligible to participate in
the Plan. All officers who are employees of the Company will be eligible to
participate in the Plan. Eligible employees who elect to participate in the Plan
shall hereinafter be referred to as "Participants".

Notwithstanding the foregoing, any employee who sells Shares purchased under the
Plan within three months of the date of purchase shall be precluded from
participating in the Plan for the next 12 months.

                                    ARTICLE 4

                             SHARES TO BE PURCHASED

The stock subject to purchase under the Plan is 10,000,000 shares (subject to
adjustment in the event of stock splits, stock dividends, recapitalization, or
similar adjustment in the Company's common stock) of the common stock, $.20 par
value, of the Company (the "Shares") which will be purchased on the open market.

                                    ARTICLE 5

                               PAYROLL DEDUCTIONS

Participants, upon entering the Plan, shall authorize payroll deductions to be
made for the purchase of Shares. The maximum deduction shall not, on a per pay
period basis, exceed a Participant's base salary or commission (in the case of
an employee who receives commission and no base salary) and deductions shall be
exclusive of overtime and net withholding and other deductions. The Participant
may authorize increases or decreases in the amount of payroll deductions. In
order to effect such a change in the amount of the payroll deductions, the
Company must receive notice of such change in the manner specified by the
Company and changes will take effect as soon as administratively possible. The
Company will accumulate and hold for the Participant's account the amounts
deducted from his/her pay. No interest shall be paid on such amounts.
Notwithstanding the foregoing, the Committee may, in its sole discretion,
authorize a special bonus payment be made to a Participant and such bonus be
designated as an employee contribution. Such employee contribution will be
entitled to receive the matching Employer Contribution described in the next
Article. The bonus may exceed the contribution limits otherwise imposed on the
Participant.

                                    ARTICLE 6

                              EMPLOYER CONTRIBUTION

The Company will match a part of the employee contribution by contributing to
the Plan an additional percentage of the employee's payroll deduction. The
Committee, from time to time, may increase or decrease the percentage of the
Company's contribution to the Participant's payroll deduction if the interests
of the Company so require. The matching contributions hereunder are not intended
to be entitlement or part of the regular compensation of any Participant. The
Company will pay all commissions relating to the purchase of the Shares under
the Plan, and the Company will pay all administrative costs associated with the
implementation and operation of the Plan.

                                    ARTICLE 7

                       AUTHORIZATION FOR ENTERING THE PLAN

An eligible employee may enter the Plan by enrolling in the Plan and specifying
his/her contribution amount in the manner authorized by the Company. Such
authorization will take effect as of the next practicable payroll period. Unless
a Participant authorizes changes to his/her payroll deductions in accordance
with Article 5 or withdraws from the Plan, his/her deductions under the latest
authorization on file with the Company shall continue from one payment period to
the succeeding payment period as long as the Plan remains in effect.

All Shares purchased under the Plan shall be purchased on the open market by a
broker designated, from time to time, by the Committee. On a monthly basis, as
soon as practicable following the month end, the Company shall remit the total
of contributions to the broker for the purchase of the Shares. The broker will
then execute the purchase order and the Plan Administrator shall allocate Shares

the event the purchase of Shares takes place over a number of days and at
different prices, then each participant's allocation shall be adjusted on the
basis of the average price per Share over such period.

                                    ARTICLE 9

                               ISSUANCE OF SHARES

The Shares purchased under the Plan shall be held by the Plan Administrator or
its nominee. Participants shall receive periodic statements that will evidence
all activity in the accounts that have been established on their behalf. Such
statements will be issued by the Plan Administrator or its nominee. In the event
a Participant wishes to hold certificates in his/her own name, the Participant
must instruct the Plan Administrator or its nominee independently and bear the
costs associated with the issuance of such certificates and pay, if required, a
small fee for each certificate so issued. Certificates for fractional Shares
will not be issued. Fractional Shares shall be liquidated on a cash basis only
in lieu of the issuance of certificates for such fractional Shares upon the
employee's withdrawal.

Each Participant may sell at any time all of any portion of the Shares acquired
under the Plan and held by the Plan Administrator by notifying the Plan
Administrator, who will direct the broker to execute the sale on behalf of the
Participant. The Participant shall pay the broker's commission and any other
expenses incurred with regard to the sale of the Shares. All such sales of the
Shares will be subject to compliance with any applicable federal or state
securities, tax, or other laws. Each participant assumes the risk of any
fluctuations in the market price of the Shares.

                                   ARTICLE 12

                            WITHDRAWAL FROM THE PLAN

A Participant may cease making contributions to the Plan at any time by changing
his/her payroll deduction to zero as described in Article 5. In order to execute
a sale of all or part of the Shares purchased under the Planand held by the Plan
Administrator, the Participant must contact the Plan Administrator directly. If
the Participant desires to withdraw from the Plan by liquidating all or part of
his/her shareholder interest, he/she shall receive the proceeds from the sale
thereof, minus the commission and other expenses on such sale.

                                   ARTICLE 13

                            NO TRANSFER OR ASSIGNMENT

A Participant's right to purchase Shares under the Plan through payroll
deduction is his/hers alone and may not be transferred or assigned to, or
availed of, by any other person.

                                   ARTICLE 14

                         TERMINATION OF EMPLOYEE RIGHTS

All of the employee's rights under the Plan will terminate when he/she ceases to
be an eligible employee due to retirement, resignation, death, termination, or
any other reason. A notice of withdrawal will be deemed to have been received
from a Participant on the day of his/her final payroll deduction. If a
Participant's payroll deductions are interrupted by any legal process, a
withdrawal notice will be deemed as having been received on the day the
interruption occurs.

                                   ARTICLE 15

                      TERMINATION AND AMENDMENT TO THE PLAN

The Plan may be terminated at any time by the Company's Board of Directors if
the interests of the Company so require. Upon such termination, or any other
termination of the Plan, all payroll deductions not used to purchase Shares will
be refunded. The Board of Directors also reserves the right to amend the Plan,
from time to time, in any respect and authorizes the Committee to approve
amendments to the Plan on its behalf.

                                   ARTICLE 16

shall prevail.
