1.    Purpose

      The purpose of this 1998 Stock Option Plan (the "Plan") of Analog Devices,
Inc. a Massachusetts corporation (the "Company"), is to advance the interests of

Devices, Inc. as defined in Section 424(f) of the Internal Revenue Code of 1986,

2.    Eligibility

      All of the Company's employees, officers, directors, consultants and
advisors are eligible to be granted options (each, an "Option") under the Plan.
Each person who has been granted an Option under the Plan is hereinafter
referred to as "Optionee".

3.    Administration; Delegation

      (a)   Administration by Board of Directors. The Plan will be administered
by the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Options and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Option in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Option. No director or person acting
pursuant to the authority delegated. by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

      (b)   Appointment of Committees. To the extent permitted by applicable

referred to in Section 3(c) to the extent that the Board's powers or authority
under the Plan have been delegated to the Committee or executive officer.

      (c)   Delegation to Executive Officers. To the extent permitted by
applicable law, the Board may delegate to one or more executive officers of the
Company the power to grant Options and exercise such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of shares subject to Options and the maximum number of shares for any one
Optionee to be made by such executive officers.

4.    Stock Available for Options

Options may be granted under the Plan for up to 15,000,000 shares of common
stock, $0.16-2/3 par value of the Company ("Common Stock"). If any Option
expires or is terminated, surrendered or canceled without having been fully
exercised or is forfeited in whole or in part or results in any Common Stock not
being issued, the unused Common Stock covered by such Option shall again be
available for the grant of Options under the Plan, subject, however, in the case
of Incentive Stock Options (as hereinafter defined), to any limitation required
under the Code. Shares issued under the Plan may consist in whole or in part of
authorized but unissued shares or treasury shares.

      (b)   Per-Optionee Limit. Subject to adjustment pursuant to Section 4(c),
the maximum number of shares of Common Stock with respect to which an Option may
be granted to any Optionee under the Plan shall be 750,000 per calendar year.

applied consistently with Section 162(m) of the Code.

      (c)   Chances in Capitalization. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, liquidation, spin-off or other similar change in
capitalization or event, or any distribution to holders of Common Stock other

under this Plan, (ii) the per-Optionee limitation set forth in Section 4(b) and
(iii) the number and class of securities and exercise price per share subject to
each outstanding Option shall be appropriately adjusted by the Company to the
extent the Board shall determine, in good faith, that such an adjustment is
necessary and appropriate. If this Section 4(c) applies and Section 6(b) also
applies to any event, Section 6(b) shall be applicable to such event, and this
Section 4(c) shall not be applicable.

the employing corporation with the Company or any subsidiary, or the acquisition
by the Company or a subsidiary of the assets of the employing corporation, or
the acquisition by the Company or a subsidiary of stock of the employing
corporation with the result that such employing corporation becomes a
subsidiary.

5.    Option Terms

      (a)   General. The Board may grant Options to purchase Common Stock and
determine the number of shares of Common Stock to be covered by each Option, the
exercise price of each Option and the conditions and limitations applicable to
the exercise of each Option, including conditions relating to applicable federal
or state securities laws, as it considers necessary or advisable. An Option
which is not intended to be an Incentive Stock Option (as hereinafter defined)
shall be designated a "Nonstatutory Stock Option".

      (b)   Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to an Optionee, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

      (c)   Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable Option Agreement;
provided, however, that the exercise price shall be not less than 100% of the
fair market value of the Common Stock, as determined by the Board, at the time
of the Option grant ("Fair Market Value").

      (d)   Option Agreement; Duration of Options. Each Option may be evidenced
by an Option Agreement in such form and containing such provisions as the Board
from time to time shall approve. Any Option not documented by written agreement
shall be memorialized by a written confirming memorandum to the Optionee stating
the material terms of the Option. (For purposes of the Plan, Option Agreement,
as defined herein, shall also include any such confirming memorandum.) Each
Option Agreement shall specify the period or periods during which the Option may
be exercised and shall specify the effect of termination of employment on the
exercisability of the Option. The Option Agreement may also include, without
limitation, provisions relating to (i) subject to the provisions of Section 6,
the acceleration and vesting of Options, (ii) a provision that permits Options
to vest and remain exercisable after the Optionee ceases to be employed by, or
retained as a

consultant or advisor to, the Company or any subsidiary or affiliate of the
Company, and (iii) any other matters not inconsistent with the terms and
provisions of this Plan that the Board shall, in its sole discretion, determine.
The terms and conditions of the respective Option Agreements need not be
identical.

      (e)   Exercise of Option. Options may be exercised by delivery to the
Company of a written notice of exercise, e-mail or other form of notice approved
by the Board together with payment as specified in Section 5(f) for the number
of shares for which the Option is exercised.

      (f)   Payment Upon Exercise. Common Stock purchased upon the exercise of
an Option granted under the Plan shall be paid for as follows:

            (1)   in cash or by check, payable to the order of the Company;

            (2)   except as the Board may, in its sole discretion, otherwise
provide in an Option Agreement, (i) delivery of an irrevocable and unconditional
undertaking by a creditworthy broker to deliver promptly to the Company
sufficient funds to pay the exercise price or (ii) delivery by the Optionee to
the Company of a copy of irrevocable and unconditional instructions to a
creditworthy broker to deliver promptly to the Company cash or a check
sufficient to pay the exercise price;

            (3)   delivery of shares of Common Stock owned by the Optionee
valued at their Fair Market Value as determined by the Board, which Common Stock
was owned by the Optionee for at least six months prior to such delivery;

            (4)   to the extent permitted by the Board, in its sole discretion,
(i) by delivery of a promissory note of the Optionee to the Company on terms
determined by the Board or (ii) by payment of such other lawful consideration as
the Board may determine; or

            (5)   any combination of the above permitted forms of payment.

6.    LIQUIDATION; ACQUISITION EVENT; CHANGE IN CONTROL

      (a)   Liquidation or Dissolution. In the event of a proposed liquidation
or dissolution of the Company, the Board shall upon written notice to the
Optionees provide that all then unexercised Options will (i) become exercisable
in full as of a specified time at least 10 business days prior to the effective
date of such liquidation or dissolution and (ii) terminate effective upon such
liquidation or dissolution, except to the extent exercised before such effective
date.

                  (a)   Acquisition Event. Upon the occurrence of an Acquisition
                        Event (regardless of whether such event also constitutes
                        a Change in Control Event), or the execution by the
                        Company of any agreement with respect to an Acquisition
                        Event (regardless of whether such event will result in a
                        Change in Control Event), the Board shall provide that
                        all of the outstanding Options shall be assumed, or
                        equivalent options shall be substituted, by the
                        acquiring or succeeding corporation (or an affiliate
                        thereof); provided that (i) any options substituted for
                        Incentive Stock Options shall satisfy, in the
                        determination of the Board, the requirements of Section
                        422 of the Code and (ii) if such Acquisition Event also
                        constitutes a Change in Control Event, except to the
                        extent specifically provided to the contrary in the
                        instrument evidencing any Option or any other agreement
                        between an Optionee and the Company, the vesting
                        schedule of such assumed or substituted options shall
                        provide (A) that one-half of the number of shares
                        subject to the Option which were not already vested
                        shall be immediately exercisable in a manner consistent
                        with that set forth in the first two sentences of
                        subsection (b) below and (B) that such assumed or
                        substituted options shall immediately become exercisable
                        in full if, on or prior to the first anniversary of the
                        date of the consummation of the Acquisition Event, the
                        Optionee's employment with the Company or the acquiring
                        or succeeding corporation is terminated for Good Reason
                        by the Optionee or is terminated without Cause by the
                        Company or the acquiring or succeeding corporation.

                              Notwithstanding the foregoing, if the acquiring or
                        succeeding corporation (or an affiliate thereof) does
                        not agree to assume, or substitute for, such Options,
                        then the Board shall (x) upon written notice to the
                        Optionees, provide that all then unexercised Options
                        will become exercisable in full as of a specified time
                        (the "Acceleration Time") prior to the Acquisition Event
                        and will terminate immediately prior to the consummation
                        of such Acquisition Event, except to the extent
                        exercised by the Optionees before the consummation of
                        such Acquisition Event, and/or (y) in the event of an
                        Acquisition Event under the terms of which holders of
                        Common Stock will receive upon consummation thereof a
                        cash payment for


                                       8
<PAGE>
                        each share of Common Stock surrendered pursuant to such
                        Acquisition Event (the "Acquisition Price"), provide
                        that all outstanding Options shall terminate upon
                        consummation of such Acquisition Event and each Optionee
                        shall receive, in exchange therefor, a cash payment
                        equal to the amount (if any) by which (A) the
                        Acquisition Price multiplied by the number of shares of
                        Common Stock subject to such outstanding Options
                        (whether or not then exercisable), exceeds (B) the
                        aggregate exercise price of such Options.

                  (b)   Change in Control Event that is not an Acquisition
                        Event. Upon the occurrence of a Change in Control Event
                        that does not also constitute an Acquisition Event,
                        except to the extent specifically provided to the
                        contrary in the instrument evidencing any Option or any
                        other agreement between an Optionee and the Company, the
                        vesting schedule of such Option shall be accelerated in
                        part so that one-half of the number of shares that would
                        otherwise have first become vested on any date or dates
                        after the date of the Change in Control Event shall
                        immediately become exercisable. The remaining one-half
                        of such number of shares that would otherwise have first
                        become vested on each subsequent vesting date shall
                        continue to become vested on each subsequent vesting
                        date in accordance with the original vesting schedule
                        set forth in such Option; provided, however, that each
                        such Option shall immediately become exercisable in full
                        if, on or prior to the first anniversary of the date of
                        the consummation of the Change in Control Event, the
                        Optionee's employment with the Company or the acquiring
                        or succeeding corporation is terminated for Good Reason
                        by the Optionee or is terminated without Cause by the
                        Company or the acquiring or succeeding corporation.

7.    Repricing of Options.

      The Board shall have the authority, at any time and from time to time,
with the consent of the affected option holders, to amend any or all outstanding
options granted under the Plan to provide an option exercise price per share
which may be lower or higher than the original option exercise price, and/or to
cancel any such options and grant in substitution therefor new options covering
the same or different numbers of shares of Common Stock having an option
exercise price per share which may be lower or higher than the exercise price of
the canceled options.


                                       9

8.    General Provisions Applicable to Options

      (a)   Transferability of Options. Except as the Board may otherwise
determine or provide in an Option, Options shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution, and, during the life of the Optionee, shall be
exercisable only by the Optionee. References to an Optionee, to the extent
relevant in the context, shall include references to authorized transferees.

      (b)   Board Discretion. Except as otherwise provided by the Plan, each
Option may be granted alone or in addition or in relation to any other Option.
The terms of each Option need not be identical, and the Board need not treat
Optionees uniformly.

      (c)   Termination of Status. The Board shall determine the effect on an
Option of the disability, death, retirement, authorized leave of absence or
other change in the employment or other status of an Optionee and the extent to
which, and the period during which, the Optionee, the Optionee's legal
representative, conservator, guardian or designated beneficiary may exercise
rights under the Option.

      (d)   Withholding. Each Optionee shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Options granted to such Optionee no later than
the date of the event creating the tax liability. Except as the Board may
otherwise provide in an Option, Optionees may satisfy such tax obligations in
whole or in part by delivery of shares of Common Stock, including shares
retained from the Option creating the tax obligation, valued at their Fair
Market Value. The Company may, to the extent permitted by law, deduct any such
tax obligations from any payment of any kind otherwise due to an Optionee.

      (e)   Amendment of Option. The Board may amend, modify or terminate any
outstanding Option, including but not limited to, substituting therefor another
Option of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Optionee's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Optionee.

      (f)   Conditions on Delivery of Stock. The Company will not be obligated
to deliver any shares of Common Stock pursuant to the Plan or to remove any
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Option have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the


                                       10
<PAGE>
issuance and delivery of such shares have been satisfied, including any
applicable securities laws and any applicable stock exchange or stock market
rules and regulations, and (iii) the Optionee has executed and delivered to the
Company such representations or agreements as the Company may consider
appropriate to satisfy the requirements of any applicable laws, rules or
regulations.

      (g)   Acceleration; Continued Vesting. The Board may at any time provide
that any Options shall become immediately exercisable in full or in part, and
may at any time provide for the continued vesting and exercisability of any
Options for such period of time after the Optionee's employment terminates as
the Board shall determine.

9.    Miscellaneous

      (a)   No Right To Employment or Other Status. No person shall have any
claim or right to be granted an Option, and the grant of an Option shall not be
construed as giving an Optionee the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with an Optionee free
from any liability or claim under the Plan, except as expressly provided in the
applicable Option.

      (b)   No Rights As Stockholder. Subject to the provisions of the
applicable Option, no Optionee or designated beneficiary of the Optionee shall
have any rights as a stockholder with respect to any shares of Common Stock to
be distributed with respect to an Option until becoming the record holder of
such shares. Notwithstanding the foregoing, in the event the Company effects a
split of the Common Stock by means of a stock dividend and the exercise price
of and the number of shares subject to such Option are adjusted as of the date
of the distribution of the dividend (rather than as of the record date for such
dividend), then an Optionee who exercises an Option between the close of
business on the record date for such stock dividend and the close of business on
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

      (c)   Effective Date and Term of Plan. The Plan shall become effective on
the date on which it is adopted by the Board. No Option shall be granted under
the Plan after ten (10) years from the earlier of (i) the date on which the Plan
was adopted by the Board or (ii) the date the Plan was approved by the Company's
stockholders, but Options previously granted may extend beyond that date.


                                       11
<PAGE>
      (d)   Amendment and Termination of Plan. The Board may terminate the Plan
at any time, except with respect to Option grants then outstanding. The Board
may amend or suspend the Plan without stockholder approval, unless such approval
is necessary to comply with applicable laws, including provisions of the
Exchange Act or the Code.

      (e)   Governing Law. The provisions of the Plan and all Options granted
hereunder shall be governed by and interpreted in accordance with the laws of
the Commonwealth of Massachusetts, without regard to any applicable conflicts of
law.

                  Adopted by the Board of Directors on January 15, 1998

                  Approved by the Stockholders on March 10, 1998

                 FIRST AMENDMENT TO THE 1998 STOCK OPTION PLAN


      Subsection 4(a) of the Plan be and hereby is deleted and the following is
inserted in lieu thereof:


            "(a)  Number of Shares. Subject to adjustment pursuant to Section
            4(c), Options may be granted under the Plan for up to 32,000,000
            shares of common stock, $0.16-2/3 par value of the Company ("Common
            Stock"). If any Option expires or is terminated, surrendered or
            canceled without having been fully exercised or is forfeited in
            whole or in part or results in any Common Stock not being issued,
            the unused Common Stock covered by such Option shall again be
            available for the grant of Options under the Plan, subject, however,
            in the case of Incentive Stock Options (as hereinafter defined), to
            any limitation required under the Code. Shares issued under the Plan
            may consist in whole or in part of authorized but unissued shares or
            treasury shares."

      That Section 7 of the Plan (Repricing of Options) be and hereby is deleted
in its entirety.

      Approved by the Board of Directors on December 8,1999 and authorized by
the shareholders on March 14,2000.

                 SECOND AMENDMENT TO THE 1998 STOCK OPTION PLAN


      The Analog Devices, Inc. 1998 Stock Option Plan, pursuant to Section 9(d)
thereof, is hereby amended as follows:

      Subsection 8(d) of the Plan be and hereby is deleted and the following is
inserted in lieu thereof:


            "(d)  Withholding. Each Optionee shall pay to the Company, or make
            provision satisfactory to the Board for payment of, any taxes
            required by law to be withheld in connection with Options granted to
            such Optionee no later than the date of the event creating the tax
            liability. Except as the Board may otherwise provide in an Option,
            Optionees may satisfy such tax obligations in whole or in part by
            delivery of shares of Common Stock, including shares retained from
            the Option creating the tax obligation, valued at their Fair Market
            Value; provided, however, that the total tax withholding when stock
            is being used to satisfy such tax obligations cannot exceed the
            Company's minimum statutory withholding obligations (based on
            minimum statutory withholding rates for federal and state purposes,
            including payroll taxes that are applicable to such supplemental
            taxable income). The Company may, to the extent permitted by law,
            deduct any such tax obligations from any payment of any kind
            otherwise due to an Optionee."

      Approved by the Board of Directors on December 5,200l.

thereof, is hereby amended as follows:

      Subsection 5(e) of the Plan be and hereby is amended by adding the
following new sentence at the end thereof:

            "The Corporation may direct that notice of option exercise be
            delivered to an agent of the Corporation designated to receive such
            delivery."

      Subsection 8(e) of the Plan be and hereby is amended by adding the
following new sentence at the end thereof:

            "Notwithstanding the foregoing, the Board shall not amend any
            outstanding option to provide an option exercise price per share
            which is lower than the original option exercise price."


      Approved by the Board of Directors on December 10,2002.
