6.4   If an Eligible Employee leaves the employment of the Company or a
Participating Company of his own accord then:

i.    any Options which cannot be exercised due to the provisions of Rule 6.1
      shall lapse, and

      6.1 on the last day of his employment with the Company or a Participating
      Company may be exercised within 90 days of such date.

6.5   If an Eligible Employee leaves the employment of the Company or a
      Participating Company due to disability or retirement, then all Options
      which on the last day of his employment are incapable of exercise due to
      Rule 6.1 shall continue to be exercisable in accordance with the Rules. An
      Employee is disabled if he is unable to engage in any substantial gainful
      activity by reason of any medically determinable physical or mental

      service with the Company, including service with any Participating Company
      and service before the Company was acquired by Analog Devices, Inc.,
      equals or exceeds 10 years. Periods when the Eligible Employee is absent
      from service due to illness, holiday, approved leave of absence or other
      similar reason shall be treated as periods of service. Service need not be
      continuous; periods of service shall be aggregated.

6.6   If an Eligible Employee leaves the employment of the Company or a
      Participating Company due to redundancy, then all Options which on the
      last day of his employment are incapable of exercise due to Rule 6.1 shall
      continue to be exercisable in accordance with the Rules, provided that any
      such Option must be exercised with
<PAGE>
      90 days of its Vesting Date. Any Option not exercised within the 90 day
      period aforesaid shall lapse.

7.1.  If a company (in this Rule referred to as "the Acquiring Company") -

      offer to;

            (i) acquire the whole of the issued ordinary share capital of Analog
            Devices Inc. which is made on condition such that if it is satisfied
            the person making the offer will have Control of Analog Devices,
            Inc., or

            (ii) acquire all the shares in Analog Devices, Inc. which are of the
            same class as the scheme Shares

the Option Holder may with the agreement of the Acquiring Company within the
"appropriate period" referred to in Rule 7.2 release each Subsisting Option
("the Old Option") in consideration of the grant of a new option ("the New
Option") which satisfies the conditions that it

i.    is over shares in the Acquiring Company or some other company falling
      within sub-paragraphs (b) or (c) of paragraph 12, Schedule 12C, to the
      Act, which satisfy the conditions specified in paragraphs 12 to 16
      inclusive, Schedule 12C, to the Act;

ii.   is a right to acquire such number of such Shares as has on acquisition of
      the New Option an aggregate Market Value equal to the aggregate Market
      Value of the Shares subject to the Old Option on its release;

iii.  has a Subscription Price per share such that the aggregate price payable
      on the complete exercise equals the aggregate price which would have been
      payable on complete exercise of the Old Option; and

iv.   is otherwise identical in terms to the Old Option.

7.2.  The "appropriate period" referred to in Rule 7.1 is 6 months beginning
with the time when the person making the offer has obtained Control of Analog
Devices, Inc. and any condition subject to which the offer is made is satisfied;

7.3.  Where an Option Holder is granted a New Option for release of his Old
Option in accordance with Rule 7.1 then;
<PAGE>
(i) the New Option shall be treated as having been acquired at the same time as
the Old Option and be exercisable in the same manner as the Old Option,

(ii) the New Option shall be subject to the provisions of the Scheme as it had
effect in relation to the Old Option immediately before the release, and

(iii) with effect from the release of the Old Option and the grant of the New
Option, the provisions of Rules 6,7,8, and 10 shall, in relation to the New
Option be construed as if references to Analog Devices Inc. and to the Shares
were references to the Acquiring Company or, as the case may be, to the other
company to whose shares the New Options relate, and to the shares in that other
company, but references to Participating Company shall continue to be construed
as if references to the Company were references to Analog Devices BV.

7.4.  For the purposes of this Rule 7 a person shall be deemed to have obtained
Control of Analog Devices Inc. if he and others acting in concert with him have
together obtained Control of it.

7.5.  The exercise of an Option pursuant to the preceding provisions of this
Rule 7 shall be subject to the provisions of Rule 8 below.

8.    MANNER OF EXERCISE OF OPTIONS

by the personal representatives of an individual who at the date of his death
was, precluded by paragraph 7, of Schedule 12C, to the Act from participating in
the Scheme.

8.2.  Subject to Rule 5.1 no Option shall be exercised at any time when the
shares which may be thereby acquired are not Shares as defined in Rule 1.1.

8.3   An Option shall be exercised by the Option Holder, or as the case may be,
his personal representatives, by

i.    by delivering to the Company a written notice of exercise, e-mail or other
      form of notice approved by the Board and accompanied by the appropriate
      payment.

8.4.  Shares shall be allotted and issued or transferred pursuant to a notice of
exercise within thirty days of the date of exercise. Save for any rights
determined by reference to a date preceding the date of allotment, such Shares
shall rank pari passu with the other Shares of the same class in issue at that
date of allotment.
<PAGE>
8.5.  When an Option is exercised only in part, the balance shall remain
exercisable on the same terms as originally applied to the whole Option and the
terms of the Option Agreement issued with respect to the whole Option shall
continue to apply to the unexercised balance. A new Option Agreement shall not
be issued.
