EXHIBIT 4.4

                       ABB EMPLOYEE SHARE ACQUISITION PLAN
                                   US SCHEDULE


(1)  INTERACTION WITH THE PLAN

     The ESAP Board has determined that it is advisable to establish a sub-Plan
     for the purpose of permitting Awards granted to certain employees of US
     Participating Companies (as defined herein), each of which is a
     Participating Company, to qualify for certain favorable Federal income tax
     treatment in the United States. The ESAP Board, therefore, has established
     a sub-Plan as set forth in this Schedule for the purpose of granting Awards
     that qualify as Incentive Stock Options (as defined herein). The terms of
     the Plan shall, subject to the modifications in this Schedule, constitute
     the US Share Acquisition Sub-Plan to the ABB Employee Share Acquisition
     Plan (the "US Sub-Plan").

     Awards granted under the US Sub-Plan shall be Incentive Stock Options;
     however, to the extent that any such Award does not qualify as an Incentive
     Stock Option (whether because of its provisions or the time or manner of
     its exercise or otherwise), such Award, or the portion thereof which does
     not so qualify, shall constitute a separate stock option other than an
     Incentive Stock Option.

     Awards granted to employees resident in the United States who are eligible
     to participate in the US Sub-Plan, pursuant to Section (5) hereof, will be
     subject to the US Sub-Plan.

(2)  DEFINITIONS

     Capitalized terms used in the US Sub-Plan shall have the same meanings as
     set forth in the ABB Employee Share Acquisition Plan unless a specific
     definition is set forth herein as follows:

     "Administrator" means ABB Inc.

     "Award" means a right to purchase Shares granted under the terms of the US
     Sub-Plan.

     "Code" means the United States Internal Revenue Code of 1986, as it may be
     amended from time to time, including regulations and rules thereunder and
     successor provisions and regulations and rules thereto.

     "Direct Hire Temporary Employee" means an individual who is hired by a US
     Participating Company as an interim replacement to supplement the work
     force or to assist in the completion of a specific project for a limited

     "casual" basis such as an intern or a summer employee.

     "Employee" means, except as set forth in the immediately following
     sentence, any person who (a)(i) is a United States citizen or (ii) has been

     Company to provide specific and self-directed services, who has the right
     to direct the means and methods of accomplishing the results without

     Non-Regular Status Worker with respect to the US Sub-Plan shall be
     determined by the US Participating Company, and that determination shall be
     final and binding, notwithstanding a contrary adjudication or any contrary
     determination by the United States Internal Revenue Service, the United
     States Department of Labor, or other governmental authority.

     "Parent" of any corporation means any present or future corporation,
     domestic or foreign, which is or would be a "parent corporation," as
     defined under section 424(e) of the Code, of such corporation.

     "Participant" means a person who holds an Award granted under the US
     Sub-Plan.

     "Regular Full-Time Employee" means an individual who is hired to work the
     normal complement of a full work week, however that period is defined by
     the individual's employer, who is paid from the payroll of the employer and
     whose duration of employment has no pre-determined end date.

     than the normal complement of a full work week, however that period is

     "Regular Status Employee" means a Regular Full-Time Employee or a Regular
     Part-Time Employee. Regular Status Employees shall be designated as such on
     the payroll records of a US Participating Company, and such designation
     shall be wholly within the US Participating Company's sole discretion.

     defined under section 424(f) of the Code, of such corporation.

     "US Participating Company" means (i) any Subsidiary of ABB Holdings Inc.,
     or (ii) any United States Subsidiary of ABB Ltd as the Administrator may
     designate for participation in the US Sub-Plan.

(3)  SHARES SUBJECT TO US SUB-PLAN AND OFFER PRICE

     (a)  For purposes of the US Sub-Plan, "Share" means an ADS representing one
          fully paid registered share of ABB, subject to adjustments by the ESAP
          Board to appropriately reflect the events described in Rule 10 of the
          Plan or any change or termination of ABB's ADR program.

                                       2


     (b)  The maximum number of Shares (after taking into account any adjustment
          in accordance with Rule 10 of the Plan relating to variations in the
          share capital of ABB) that may be issued under the US Sub-Plan shall
          be 10,000,000 Shares.

     (c)  For purposes of the US Sub-Plan, the Offer Price of an Award shall be
          the closing price of a Share on the New York Stock Exchange on the
          Grant Date of such Award, as determined by the ESAP Board in
          accordance with the Plan. The Offer Price of an Award shall be stated
          in US Dollars.

(4)  ADMINISTRATION

     (a)  The Administrator shall administer, manage and operate the US Sub-Plan
          in accordance with its terms and conditions; provided, however, that
          the Administrator shall have no authority to take any action pursuant
          to Rule 10 or Rule 11 of the Plan, subject to the Administrator's
          authority to amend the US Sub-Plan in accordance with Section (11)
          hereof.

     (b)  The Administrator shall have all authority that may be necessary or
          helpful to enable it to discharge its responsibilities with respect to
          the US Sub-Plan. Without limiting the generality of the foregoing
          sentence or Section (4)(a), and in addition to the powers otherwise
          expressly designated to the Administrator herein, the Administrator
          shall have the exclusive right and discretionary authority to
          interpret the US Sub-Plan and ancillary agreements and documents
          relating to the US Sub-Plan; construe any ambiguous provision of the
          US Sub-Plan and/or any such agreements and documents and decide all
          questions concerning eligibility to participate in the US Sub-Plan.
          The Administrator may establish, amend, waive and/or rescind rules and
          regulations and administrative guidelines for carrying out the US
          Sub-Plan and may correct any errors, supply any omissions or reconcile
          any inconsistencies in the Plan (as it relates to the US Sub-Plan),
          the US Sub-Plan and/or any ancillary agreements and documents of the
          US Sub-Plan. The Administrator shall have full discretionary authority
          in all matters related to the discharge of its responsibilities and
          the exercise of its authority under the US Sub-Plan. Decisions and
          actions by the Administrator with respect to the US Sub-Plan and any
          ancillary agreement or document of the US Sub-Plan shall be final,
          conclusive and binding on all persons having or claiming to have any
          right or interest in or under the US Sub-Plan and/or any such
          agreement or document.

     (c)  Except to the extent prohibited by applicable law or the applicable
          rules of any stock exchange, the Administrator may, in its discretion,
          allocate all or any portion of its responsibilities and powers under
          this Section (4) to any one or more of its employees and/or delegate
          all or any part of its responsibilities and powers under this Section
          (4) to any person or persons selected by it; provided, however, that
          the Administrator may not delegate its authority to correct errors,
          omissions or inconsistencies in the Plan or the US Sub-Plan. Any such
          authority delegated or allocated by the Administrator under this
          Section (4) shall be exercised in accordance with the terms and
          conditions of the US Sub-Plan and any rules, regulations or
          administrative guidelines that may from time to time be established by
          the Administrator, and any such allocation or delegation may be
          revoked by the Administrator at any time.


(5)  ELIGIBILITY

     (a)  An individual is eligible to participate in the US Sub-Plan if (and
          only if):

                                       3


     (i)  he is on the Grant Date an Employee; and

     (ii) he either:

          (1)  is paid on a salaried basis, is classified as a Regular Status
               Employee and not a Non-Regular Status Worker, and is not
               represented by a collective bargaining agent, or if represented,
               the collective bargaining agreement provides for participation in
               the US Sub-Plan, or

          (2)  is a domestic non-union hourly paid Employee, except for any such
               Employee as may be designated by the Administrator as ineligible
               for participation in the US Sub-Plan, or a member of those
               certain domestic union hourly paid groups whose collective
               bargaining agreement provides for participation in the US
               Sub-Plan.

     (b)  Notwithstanding anything in paragraph (a) of this Section (5) to the
          contrary, an Employee who is on a leave of absence on the Grant Date
          shall not be eligible to participate in the US Sub-Plan.

     (c)  If an individual employed by the US Participating Company is not
          eligible to participate in the US Sub-Plan, he shall not be eligible
          to participate in the Plan.

     (d)  A leave of absence of a Participant shall not be deemed a termination
          of employment of the Participant for purposes of the US Sub-Plan to
          the extent permitted by the Code with respect to Incentive Stock
          Options, so long as such leave of absence is duly authorized in
          writing by the Administrator and such authorization expressly permits
          continued participation in the US Sub-Plan during such leave of
          absence.

     (e)  This Section (5) of the US Sub-Plan is subject to the provisions of
          Rule 7 of the Plan.

(6)  CERTAIN LIMITATIONS ON AWARDS

     (a)  Notwithstanding any intent to grant an Incentive Stock Option, an
          Award granted under the US Sub-Plan will not be considered an
          Incentive Stock Option to the extent that it, together with any other
          "incentive stock options" (within the meaning of Section 422 of the
          Code, but without regard to subsection (d) of such Section) granted
          under the US Sub-Plan, and under any other "incentive stock option"
          plans of the employer US Participating Company, any Subsidiary of such
          US Participating Company and any Parent of such US Participating
          Company, are exercisable for the first time by any Participant during
          any calendar year for Shares having an aggregate fair market value
          (determined as of the Grant Date of such Award) in excess of
          US$100,000 (or such other limit as may be required by the Code). The
          rule set forth in the preceding sentence shall be applied by taking
          Awards into account in the order in which they were granted and in
          compliance with Code Section 422(d).

     (b)  No Incentive Stock Option shall be granted to an individual otherwise
          eligible to participate in the US Sub-Plan who owns (within the
          meaning of Section 424(d) of the Code), at the time the Award is
          granted, more than ten percent (10%) of the total combined voting
          power of all classes of stock of the US Participating Company
          employing the individual or a Subsidiary or Parent of such US
          Participating Company. This restriction does not apply if at the time
          such Incentive Stock Option is granted the

                                       4


          Offer Price per Share subject to the Incentive Stock Option is at
          least 110% of the fair market value of a Share on the date such
          Incentive Stock Option is granted, and the Incentive Stock Option by
          its terms is not exercisable after the expiration of five years from
          such date of grant.

(7)  NO TRANSFER OF AWARDS

     An Award by its terms shall be personal and may not be sold, transferred,
     pledged, assigned, encumbered or otherwise alienated or hypothecated by the
     Participant to whom such Award was granted, and such Award shall be
     exercisable only by such Participant.

(8)  CONDITIONS UPON ISSUANCE OF SHARES

     Shares shall not be issued with respect to an Award unless the exercise of
     such Award and the issuance and delivery of such Shares pursuant thereto
     shall comply with all applicable provisions of law of the United States,
     including, without limitation, the Securities Act of 1933, as amended; the
     Securities Exchange Act of 1934, as amended; the rules and regulations
     respectively promulgated thereunder; and the requirements of any stock
     exchange or quotation system upon which the Shares may then be listed or
     quoted; and shall be further subject to the approval of counsel for ABB
     Holdings or a US Participating Company with respect to such compliance.

     As a condition to the exercise of an Award, ABB Holdings or a US
     Participating Company may require the Participant exercising such Award 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 and may require any other representation or
     warranty if, in the opinion of counsel for ABB Holdings or a US
     Participating Company, such a representation is required by any of the
     aforementioned applicable provisions of law.

(9)  EMPLOYEE SHARE ACCOUNT

     Any Shares transferred to a Participant upon exercise of such Participant's
     Award under the US Sub-Plan shall be held in such Participant's Employee
     Share Account in accordance with Rule 5 of the Plan, and shall not be
     transferred out of such Employee Share Account before the earliest to occur
     of (a) one year after the transfer of such Shares to such Participant and
     (b) such Participant's disposition of such Shares, subject to the last
     sentence of Rule 5(1) of the Plan.

(10) APPLICABLE LAW

     The US Sub-Plan and all rights hereunder shall be governed by and construed
     in accordance with English law. Should any provision of the US Sub-Plan be
     determined by a court of competent jurisdiction to be unlawful or
     unenforceable, such determination shall in no way affect the application of
     any of the remaining provisions of the US Sub-Plan.

(11) AMENDMENT OF US SUB-PLAN

     The Administrator may at any time, and from time to time, with or without
     prior notice, amend, alter, suspend or terminate the US Sub-Plan,
     retroactively or otherwise; provided, however, that no such amendment,
     alteration, suspension or termination shall violate the terms and
     conditions of the Plan; provided further, however, that, except as provided
     in Rule 10 of the Plan relating to variation in the share capital of ABB,
     no such amendment shall be effective unless approved by

                                       5


     the shareholders of ABB and/or the shareholder of ABB Holdings, to the
     extent shareholder approval is necessary to satisfy any requirements of the
     Code relating to Incentive Stock Options.

     The Administrator may amend the terms of any Award theretofore granted,
     including any document or agreement relating thereto, retroactively or
     otherwise; provided, however, that no such amendment shall violate the
     terms and conditions of the Plan.

(12) SHAREHOLDER APPROVAL

     The US Sub-Plan shall be effective as of the date upon which it shall be
     adopted by the ESAP Board and the Board of Directors of ABB Holdings. The
     maximum number of Shares that may be issued under the US Sub-Plan and the
     employees eligible to participate in the US Sub-Plan shall be submitted to
     the shareholders of ABB and the shareholder of ABB Holdings for approval
     within twelve (12) months before or after the date of adoption of the US
     Sub-Plan by the ESAP Board and the Board of Directors of ABB Holdings.
     Notwithstanding any other provisions of the US Sub-Plan to the contrary, if
     the shareholders of ABB or the shareholder of ABB Holdings fail to approve
     such provisions of the US Sub-Plan within twelve months of such adoption of
     the US Sub-Plan, any Awards previously granted under the US Sub-Plan shall
     not qualify as Incentive Stock Options, but, rather, shall constitute stock
     options other than Incentive Stock Options.


(13) DURATION

     The US Sub-Plan shall terminate upon the earliest to occur of:

     (a)  the effective date of a resolution adopted by the Administrator
          terminating the US Sub-Plan;

     (b)  the effective date of termination of the Plan by the ESAP Board;

     (c)  the date all Shares subject to the US Sub-Plan are delivered pursuant
          to the US Sub-Plan's provisions; or

     (d)  ten (10) years from the date the US Sub-Plan becomes effective in
          accordance with Section (12) of the US Sub-Plan.

     No Award may be granted under the US Sub-Plan after the earliest to occur
     of the events or dates described in the foregoing paragraphs (a) through
     (d) of this Section (13); however, Awards theretofore granted may extend
     beyond such date.

     All Awards previously granted under the US Sub-Plan shall continue in force
     and in operation after the termination of the US Sub-Plan, except as they
     may be otherwise terminated in accordance with the terms of the US
     Sub-Plan.

                                    PREAMBLE

     The Plan is a discretionary benefit offered by the ABB Group for the
     benefit of its employees, the purpose of which is to increase the interest
     of the employees in ABB's business goals and results through share
     ownership. The Plan is intended to encourage the employees' commitment to
     the goals of the ABB Group; shares purchased under the Plan, or any gain
     achieved by such acquisition, are not part of salary. The Plan is being
     offered for the first time in 2004 in selected countries and the ESAP Board
     shall have the right to decide, in its sole discretion, whether or not
     another Plan will be offered in the future and to which Participating
     Companies it shall extend.

     The Plan is a share purchase program where employees can choose to enroll
     and commit to save, into a Savings Account, a sum of money regularly for a
     period of twelve months at the end of which they have the choice to buy ABB
     shares at a price fixed at the beginning of the period, or to have their
     savings returned with interest. A plan cycle begins with the Invitation
     Date when invitations to participate are issued, followed by a 12-month
     "Savings Period" and ends at the execution of participants' purchase
     decision. Shares purchased under the Plan will be held in an Employee Share
     Account for and on behalf of the Participants. The employees interact
     directly with the Bank for further transactions of these shares.

     Participating in the Plan is an investment opportunity distinct from the
     employment contract. Each Participant therefore has to take his/her own
     investment advice and be responsible for the consequences of his/her
     participation in the Plan. By choosing to participate in the Plan the
     employee is treated as being aware of any risks associated with the
     investment and accepts them on his/her own free will.

     The detailed rules for the Plan are set out below. These rules together
     with the Savings Terms and the terms and conditions applicable to the
     Employee Share Account held with the Bank contain the legal terms and
     conditions regulating the Plan.

     All the definitions of the capitalised terms used in this document can be
     found in Rule 13 below.



1.   ELIGIBILITY

     An individual is eligible to be granted an Award under the Plan if :

     (a)  he is on the Grant Date an employee of a Participating Company; and

     (b)  he either:

          (i)  on the Grant Date, has an employment contract with a
               Participating Company with an indefinite term; or

          (ii) on the Grant Date, has an employment contract with a
               Participating Company with a fixed term that will not expire
               until the end of the Savings Period; or

          (iii) on the Grant Date, has an employment contract with a
               Participating Company with a fixed term and has been an employee
               of a Group Company for a period of 12 months immediately
               preceding the Invitation Date; or

          (iv) has been declared eligible to participate by the ESAP Board.

     Eligibility is to be reviewed by Participating Companies in accordance with
     the above principles.

                                      -1-


2.   GRANT OF AWARDS

     (b)  has enrolled in the Plan and agreed to the Savings Terms under which
          he/she commits to make regular savings for a period of twelve months
          towards the purchase of the Shares. Pursuant to the Savings Terms, the
          savings shall be held by the Trustee on behalf of the Participants in
          a bank account operated by the Bank.

     To participate in the Plan, an eligible employee has to agree to make
     regular savings that can be used to buy the shares at the end of the
     Savings Period.

(2)  Subject to Rule 3(2), the amount of the monthly contribution under the
     Savings Terms, and expressed in the Savings Currency, shall be the amount
     that the individual shall have specified in his/her application form that
     he is willing to save under the Savings Terms, provided that such amount
     shall not exceed:

     (a)  such amount as is equal to 10% of his/her monthly gross salary (such
          amount to be determined in the absolute discretion of the
          Participating Company for which the individual works having regard to
          recurring cash items over the six months immediately preceding the
          Invitation Date) before any deductions; or

     (b)  the Local Currency Equivalent of Swiss Francs 750 or such other
          maximum permitted amount and in such other currency, which may vary
          from country to country, as may from time to time be determined by the
          ESAP Board,

     whichever is lower.

     The ESAP Board may, in exceptional circumstances, allow such amount to be
     decreased during the term of the Savings Period.

     At the outset, employees can choose how much to save each pay day. This
     amount is fixed for the entire Savings Period, unless the ESAP Board
     approves, under exceptional circumstances, a decrease in the amount. There
     is a maximum savings amount, being the lower of 10% of monthly gross salary
     or Swiss Francs 750 a month. Savings are made in local currency.

(3)  Subject to Rule 3, the maximum number of Shares (to be known as the Maximum
     Participation) in respect of which an Award may be granted to any
     individual shall be the number calculated in the following way:

     (a)  the monthly amount determined by Rule 2(2) (ignoring any later
          reduction in this amount as may be permitted by the ESAP Board) shall
          be multiplied by 12;

     (b)  the Swiss Franc Equivalent of this figure shall be calculated, if
          applicable;

     (c)  this will be divided by the Offer Price for that Award;

     (d)  this will be multiplied by 110%; and

     (e)  this will then be rounded up to the next multiple of 10 Shares.

                                      -2-


     The Offer Price and the maximum number of shares that you can buy at the
     end of the Savings Period, called the Maximum Participation, are set at the
     beginning of a plan cycle. The calculation of the Maximum Participation
     deals with exchange rate movements between your local currency and the
     Swiss Franc and accounts for the interest to be earned on your savings by
     integrating a 10% allowance. If your local currency strengthens against the
     Swiss Franc, you may receive a refund of monies in excess of the amount
     necessary to purchase the Maximum Participation. On the contrary, if your
     local currency weakens against the Swiss Franc, your total savings and
     interest may not be sufficient to buy the Maximum Participation and you
     will have the choice (but not the obligation) to make a "top-up" payment if
     you wish to purchase the Maximum Participation.

(4)  The price in Swiss Francs at which Shares may be acquired under an Award
     granted on any day shall be determined by the ESAP Board and stated on that
     day, and the price shall be the closing price paid for Shares on the Stock
     Exchange on the Grant Date of the Award or as otherwise provided in the
     relevant country schedule, if any.

     The price at which shares may be bought at the end of the Savings Period is
     set at the beginning of the Savings Period. The price is expressed in Swiss
     Francs.

(5)  Awards shall normally be granted within one month from the Invitation Date
     and, as soon as reasonably practicable after the Grant Date, the Plan
     Administrator shall notify the Participants of the Offer Price, the Maximum
     Participation of the Award and the interest applicable to the contributions
     under the Savings Terms.

     Participants will be sent a confirmation letter showing the key details of
     their participation.

(6)  An Award granted under the Plan to any individual shall not be capable of
     being pledged or transferred by him.

     Securities laws require ABB to limit participation in the Plan to ABB
     employees only.



3.   LIMITS

(1)  No Awards shall be granted under the Plan to the extent that they exceed
     the number of Shares specified by the ESAP Board before the Grant Date as
     being available for the Plan.

(2)  If the grant of Awards under the Plan on any day would but for this
     sub-rule cause any limit referred to in Rule 3(1) to be breached, the ESAP
     Board shall determine in a fair and reasonable manner how the grant of
     Awards should be scaled down.

     ABB may specify a maximum number of shares that will be available any given
     year under the Plan. If there is over subscription in any year, awards will
     have to be scaled back in a fair way.


4.   BUYING OF SHARES

(1)  The buying of Shares subject to an Award shall be effected in the form and
     manner prescribed by the ESAP Board and communicated before the end of the
     Savings Period.

     Before the end of the Savings Period, you will be told the process to
     follow to buy shares or to ask for your savings and interest to be repaid.

(2)  Subject to Rule 9, the buying of Shares subject to an Award shall take
     place on the date when the purchase decision is communicated and shall be
     completed on the Settlement Date and not before.

                                      -3-


(3)  The maximum number of Shares subject to an Award that may be purchased
     shall not exceed the Maximum Participation of that Award. Should the
     balance of the savings and accrued interest not be sufficient for that
     purpose, the Participant may contribute via his/her Participating Company
     an appropriate amount of money to allow the purchase of the Maximum
     Participation by such date as specified by the ESAP Board. Alternatively,
     if the balance of the account exceeds the amount required to purchase the
     Maximum Participation, the excess shall be refunded to the Participant.

     When setting the Maximum Participation, an allowance is made for foreign
     exchange fluctuations. In some cases the savings and interest at the end of
     the plan cycle will be insufficient to buy this maximum number of shares.
     You will have the choice (but not an obligation) to make a "top up" payment
     via payroll at the end of the plan cycle so that, if you wish, you can buy
     your Maximum Participation.

(4)  If the Participant goes on maternity or paternity leave, military service,
     long term sickness or disability, or retires, and as a result thereof there
     is no payroll or insufficient payroll to deduct the Participant's monthly
     contributions in accordance with the Savings Terms, the contributions shall
     be interrupted and the Participant may remain enrolled in the Plan without
     adding more savings. At the end of the Savings Period, the Participant
     shall have the right to contribute an appropriate amount of money if he/she
     wishes to purchase the Maximum Participation in accordance with Rule 4(3).

(5)  On the date and by such time as specified by the ESAP Board pursuant to
     Rule 4(1), the Participant must have notified the Company in such manner as
     the ESAP Board may determine that he/she either:

     (a)  wishes to buy the Maximum Participation at the Offer Price and has
          given the appropriate authority for the accumulated contributions and
          interest paid pursuant to the Savings Terms and the payment envisaged
          by Rule 4(3), if any, to be transferred to the Company (or such other
          person as the ESAP Board may select) in order to pay for the Shares;
          or

     (b)  wishes to buy the maximum number of Shares possible at the Offer Price
          using the Swiss Francs Equivalent of the accumulated contributions and
          interest and has given the appropriate authority for such sum to be
          transferred to the Company (or such other person as the ESAP Board may
          select) in order to pay for the Shares; or

     (c)  does not wish to buy the Shares subject to that Award and has given
          the appropriate instruction for the accumulated contributions and
          interest paid pursuant to the Savings Terms to be repaid.

     At the end of the Savings Period, you have three choices: (1) buy the
     Maximum Participation (using the possibility to make a top-up payment), (2)
     use all your savings and interest (but no top up payment) to buy shares, or
     (3) ask for the savings and interest to be returned to you. You will have
     limited time to communicate this important choice.

(6)  If the notification has not been made by the time specified in Rule 4(5) or
     if the notification is incomplete or otherwise defective, then this Rule
     4(6) shall be the authority for the ESAP Board (or any other person
     nominated by the ESAP Board) to repay the accumulated contributions and
     interest paid pursuant to the Savings Terms to the Participant in full and
     final settlement and the Award shall forthwith lapse.

     If you do not make a choice or do not comply with the purchase process,
     your savings and interest will be returned to you.

                                      -4-


(7)  If the Participant has elected to purchase the Maximum Participation and if
     the appropriate amount of money referred to in Rule 4(3) necessary thereto
     has not been made available by the Participant by the date specified by the
     ESAP Board, then this Rule 4(7) shall be the authority for the ESAP Board
     (or any other person nominated by the ESAP Board) to repay the accumulated
     contributions and interest paid pursuant to the Savings Terms to the
     Participant in full and final settlement and the Award shall forthwith
     lapse.

     If you do not make available the money necessary to top-up, your savings
     and interest will be returned to you.

(8)  In a case where any Group Company would be obliged to (or would suffer a
     disadvantage if it were not to) account, or has already been obliged to
     account, for any tax and/or for any social security contributions (in any
     jurisdiction) for which the Participant would be liable by virtue of
     his/her ownership or vesting of the Award or the purchase of Shares subject
     to the Award (together, the "Tax Liability") or any dealing costs
     associated with the sale of the Shares, this Rule 4(8) shall be the
     authority for the ESAP Board (or any other person nominated by the ESAP
     Board) to secure that payment of the Tax Liability and any such dealing
     costs is made (whether by authorising the sale of some or all of the Shares
     on his/her behalf and the payment to the Group Company of the relevant
     amount out of the proceeds of sale or otherwise).

     If your employer has to account for any tax on any profit made by you under
     the Plan, this clause authorises a sufficient number of your shares to be
     sold and for the sale proceeds to be used to pay the tax.

(9)  Where Shares subject to an Award are bought, the ESAP Board, shall procure
     the issue or transfer of those Shares on the Settlement Date to the
     Employee Share Account opened with the Bank.



5.   EMPLOYEE SHARE ACCOUNT

     (1)  After the Settlement Date, the Participant may elect to:

          (a)  keep the Shares in the Employee Share Account;

          (b)  transfer some or all of the Shares to his/her own brokerage
               account at his/her own cost . Should the Participant request the
               Bank to transfer the Shares to him/her, the Bank shall only be
               required to transfer such number of Shares rounded down to the
               nearest whole number and any fraction of a Share shall be
               forfeited by the Participant; or

          (c)  sell some or all of the Shares at any time and receive the sales
               proceeds (less handling charges, taxes and duties).

          However, if the Participant is no longer employed by any Group
          Company, the Participant needs to transfer his/her Shares out of the
          Employee Share Account in accordance with Rule 6 below.

(2)  The terms and conditions applicable to the Employee Share Account are set
     out in a separate document issued to the Participant during the Savings
     Period.

                                      -5-


     The Employee Share Account is an arrangement where the Bank looks after
     your Shares for you. The cost of this service is met by ABB. Financial
     benefits derived from the ownership of Shares, such as dividend
     distributions, will automatically be reinvested in additional Shares, or
     fractions thereof, bought at the market price for you. You can ask for some
     or all of the Shares to be sold or taken out of the Employee Share Account
     at any time. You should note that it will not be possible for you to vote
     the shares while they are held in the Employee Share Account; this is
     because of administrative difficulties in arranging this.



6.   CESSATION OF EMPLOYMENT

(1)  Subject to Rule 6(2) below, if for any reason, any Participant ceases to be
     an employee of a Group Company then:

     (a)  any subsisting Award held by that Participant and for which the
          associated Savings Period has not been completed shall lapse on the
          date of cessation of employment and the Shares subject to that Award
          may not be bought;

     (b)  the accumulated contributions (but no interest thereon) made under the
          Savings Terms associated with any Award as referred to in paragraph
          (a) above will be returned to the Participant; and

     (c)  any Shares held by the Bank must be transferred out of the Employee
          Share Account within 60 (sixty) days of the last day of employment.

     For the avoidance of doubt, if a Participant ceases to be an employee of a
     Group Company after he/she has completed the Savings Period, paragraphs (a)
     and (b) above shall not apply.

(2)  Rule 6(1) shall not apply in case of retirement of a Participant. In case
     of retirement, a Participant shall transfer out of the Employee Share
     Account any Shares held with the Bank within 60 (sixty) days of the later
     of: (i) the last day of employment, or, to the extent the Participant is
     enrolled in any given Plan cycle, (ii) the Settlement Date.

(3)  If a Participant fails to give the appropriate instructions as may be
     reasonably required by the Bank in order to transfer the Shares out of the
     Employee Share Account as envisaged by Rules 6(1)(c) and 6(2) above, the
     terms and conditions applicable to the Employee Share Account will provide
     that the Shares shall be sold and the sale proceeds (less any dealing
     costs) shall be sent to the Participant.

(4)  A Participant shall not be treated for the purposes of this Plan as having
     ceased to be an employee of a Group Company until such time as he/she is no
     longer employed by any Group Company.

     The Plan is a Plan for employees. Should you leave ABB before the end of a
     plan cycle, for whatever reason, you will lose the right to buy the shares
     but you will not lose your savings.



7.   TRANSFER OF EMPLOYMENT

(1)  If a Participant's employment is transferred to another Group Company whose
     registered office is in the same country as that of the original
     Participating Company, the Participant shall continue to participate in the
     Plan on exactly the same terms.

                                      -6-


(2)  If a Participant's employment is transferred to another Group Company whose
     registered office is in a different country to that of the original
     Participating Company, then:

     (a)  the Participant shall have the right to remain in the Plan but shall
          be prevented from making further contributions under the Savings
          Terms;

     (b)  the Award shall not lapse and the Participant is, subject to
          applicable laws, entitled to purchase Shares in accordance with Rule 4
          as if the Savings Period had continued as contemplated, and, for the
          avoidance of doubt, a Participant will be entitled to purchase his/her
          Maximum Participation in accordance with Rule 4(3); and

     (c)  for the avoidance of doubt, any Shares held by the Bank in the
          Employee Share Account on behalf of the Participant do not have to be
          transferred out of the account.


8.   EXITING THE PLAN

     Where, before the expiration of the Savings Period, the Participant
     requests repayment of the contributions made under the Savings Terms or
     otherwise withdraws his/her savings made under the Savings Terms, then:

     (a)  the Award shall immediately lapse and the Shares subject to that Award
          may not be bought;

     (b)  the accumulated contributions (but no interest thereon) shall be
          repaid as soon as reasonably practicable; and

     (c)  for the avoidance of doubt, any Shares held by the Bank in the
          Employee Share Account on behalf of the Participant do not have to be
          transferred out of this account.

     Participation is voluntary and participants are free to withdraw from the
     Plan at any time. Savings made by an employee will always be returned;
     interest will not be earned because interest is only payable at the end of
     the Savings Period. The right to buy the shares is lost.


9.   CHANGE OF CONTROL

(1)  Unless otherwise decided by the ESAP Board, if there is a Change of Control
     of ABB, the following shall occur:

     (a)  ESAP Board shall notify every Participant thereof as soon as
          practicable;

     (b)  the Savings Period shall end on the date the Change of Control is
          notified as set out in paragraph (a) above;

     (c)  every Participant shall be entitled to buy the Shares subject to an
          Award up to the Maximum Participation on such date as the ESAP Board
          may specify provided that this is not more than 45 days after the
          notification referred to in paragraph (a) and this date shall be the
          new Settlement Date of all Awards ; and

     (d)  if the Shares are not purchased at that time, the Award shall lapse.

                                      -7-


     Notwithstanding the foregoing, in the event of a Change of Control, the
     ESAP Board will, depending on prevailing circumstances, consider the
     possibility to procure the alternative for Participants to purchase shares
     of the acquiring company rather than the Shares. In such a case, the ESAP
     Board shall take advice from a financial institution of good international
     standing with respect to the number of shares and the price per share which
     should apply with respect to the Awards.

     For the avoidance of doubt, the provisions of Rule 4 as modified by this
     Rule 9(1) shall apply in the case of Change of Control.

(2)  For the purposes of Rule 9(1), a "Change of Control" means the acquisition
     in one or more transactions by any person or group, directly or indirectly,
     of beneficial ownership of shares representing more than fifty percent
     (50%) of the voting rights pertaining to the outstanding shares of common
     stock of ABB; provided, however, that any acquisition by ABB or any of its
     subsidiaries, or any employee benefit plan (or related trust) sponsored or
     maintained by ABB or any of its subsidiaries shall not constitute a Change
     of Control.

     In case of a takeover of ABB, you will be notified and you will maintain
     your right to buy Shares to the same extent as envisaged. However, you will
     most likely be offered to make your decision in the weeks following the
     change of control rather than at the end of the plan cycle. You will be
     given further detailed information should these circumstances ever arise.


10.  VARIATION OF CAPITAL

(1)  In the event of any variation of the share capital of ABB, the payment of a
     special dividend or other comparable event as determined by the ESAP Board,
     the ESAP Board will take advice from a financial institution of good
     international standing with respect to appropriate adjustments (if any) to:

     (a)  the number of Shares subject to an Award; and/or

     (b)  the price at which Shares may be bought.

(2)  As soon as reasonably practicable after making any adjustment under this
     Rule 10, the ESAP Board shall give notice in writing thereof to any
     Participant affected thereby.

     If there is any future change to the Shares, which could adversely affect
     your right to buy Shares, you will be informed of any change made to your
     right to buy the Shares.



11.  ALTERATIONS

     The ESAP Board acting fairly and reasonably may at any time alter the rules
     of the Plan and the terms of any Awards granted under it. This shall
     include, and shall not be limited to, the ESAP Board deciding to make some
     adjustments to the Rules due to local requirements, to bring forward the
     Settlement Date and permitting the early purchase of Shares or the return
     of the monies saved as a result of unforeseen circumstances.

                                      -8-


12.  MISCELLANEOUS

(1)  For the sole purpose of the administration, operation and fulfilment of the
     Plan and Participant's participation, personal data about the Participant
     (including (i) Participant's name, (ii) Participant's birth date, (iii)
     Participant's mailing address, (iv) Participant's monthly contribution, (v)
     payroll/bank account number/Brokerage account number, (vi) the company and
     the country codes and (vii) ABB internal personnel number (the "Personal
     Data")) may be transferred to and processed by his/her employing company
     and third parties (including the Plan Administrator, the Trustee, the Bank)
     in and outside of the Participant's country without further notification.
     Such Personal Data may be stored and used for further reference after the
     Participant's participation in the Plan has terminated for whatever reason.
     The Participant expressly consents to such processing and transfer of
     his/her Personal Data.

(2)  The Plan (including the Savings Terms) is an investment opportunity
     distinct from the employment contract. Each Participant therefore has to
     take his/her own investment advice and be responsible for the consequences
     of his/her participation in the Plan. The Participant understands that
     he/she is investing in securities of a listed company, the value of which
     is subject to fluctuation. The Participant understands, inter alia, that
     the value of the Shares may fluctuate between the notification of the
     decision pursuant to Rule 4(5) and the Settlement Date.

(3)  Participants may be subject to regulations on insider dealings in the
     respective jurisdictions. Therefore, Participants are advised to consult
     with legal advisors in their jurisdiction as to any restrictions with
     regard to participating in the Plan or dealing with the Shares conveyed
     under the Plan. For the avoidance of doubt, Participants are also reminded
     that they shall comply with ABB policies with respect to insider trading.

(4)  The rights and obligations of any individual under the terms of his/her
     office or employment with a Group Company shall not be affected by his/her
     participation in this Plan or any right which he may have to participate in
     it and, for the avoidance of doubt, it is hereby expressly confirmed that
     participation in the Plan on one or more occasion shall not confer on an
     individual any additional rights under his/her contract of employment and
     shall not constitute part of any individual's remuneration. An individual
     who participates in the Plan hereby waives any and all rights to claim for
     compensation or damages as a result of the application of these Rules in
     case of termination of the Participant's office or employment for any
     reason whatsoever.

(5)  In the event of any dispute or disagreement as to the interpretation of
     this Plan, or as to any question or right arising from or related to this
     Plan, the decision of the ESAP Board shall be final and binding upon all
     persons. In case of discrepancy between the English version of the Rules
     and a translation thereof in any other language, the English version of the
     Rules shall take precedence.

(6)  No Group Company makes any representation as to the tax consequences
     (including any social security contributions) for any Participant in
     respect of his/her participation in the Plan. The tax treatment is
     difficult to predict and varies from country to country and from time to
     time. Each Participant therefore has to inform himself/herself of and be
     responsible for the tax consequences (including any social security
     contributions) of his/her participation in the Plan.

(7)  Any notice or other communication under or in connection with this Plan may
     be given by personal delivery or by sending it by post, in the case of a
     company to its registered office, and in the case of an individual either
     to his/her last known address or to the address of the place of

                                      -9-


     business at which he performs the whole or substantially the whole of the
     duties of his/her office or employment or to his/her allocated corporate
     e-mail address.

(8)  The Rules of this Plan and the rights and obligations of any person
     thereunder shall be governed by and construed in accordance with the laws
     of England and Wales, and all parties shall respect the exclusive
     jurisdiction of the Courts of the district of Zurich.
