INTERESTS OF NAMED EXPERTS AND COUNSEL Hale and Dorr LLP has opined as to the legality of the securities being offered by this Registration Statement. Paul P. Brountas, Esq., a partner of Hale and Dorr LLP, serves as Clerk of the Registrant. Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS Article 6A of the Registrant's Restated Articles of Organization (the "Articles of Organization") provides for indemnification of directors and officers to the full extent permitted under Massachusetts law. Section 67 of Chapter 156B of the Massachusetts General Laws provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in the best interests of the corporation, provided that, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged not to be entitled to indemnification under Section 67. Article 6A also provides for indemnification of directors and officers of the Registrant against liabilities and expenses in connection with any legal proceedings to which they may be made a party or with which they may become involved or threatened by reason of having been an officer or director of the Registrant or of any other organization at the request of the Registrant. Article 6A generally provides that a director or officer of the Registrant (i) shall be indemnified by the Registrant for all expenses of such legal proceedings unless he has been adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interests of the Registrant, and (ii) shall be indemnified by the Registrant for the expenses, judgments, fines and amounts paid in settlement and compromise of such proceedings. No indemnification will be made to cover costs of settlements and compromises if the Board determines by a majority vote of a quorum consisting of disinterested directors (or, if such quorum is not obtainable, by a majority of the disinterested directors of the Registrant), that such settlement or compromise is not in the best interests of the Registrant. Article 6A permits the payment by the Registrant of expenses incurred in defending a civil or criminal action in advance of its final disposition, subject to receipt of an undertaking by the indemnified person to repay such payment if it is ultimately determined that such person is not entitled to indemnification under the Articles of Organization. No advance may be made if the Board of Directors determines, by a majority vote of a quorum consisting of disinterested directors (or, if such quorum is not obtainable, by a majority of the disinterested directors

of the Registrant), that such person did not act in good faith in the reasonable belief that his action was in the best interest of the Registrant. Article 6D of the Registrant's Articles of Organization provides that to the full extent permitted under Massachusetts law no director shall be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of a director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unauthorized distributions or loans under Section 61 or 62 of Chapter 156B, or (iv) for any transaction from which the director derived an improper personal benefit. The Registrant has directors and officers liability insurance for the benefit of its directors and officers. Item 7. EXEMPTION FROM REGISTRATION CLAIMED Not applicable. Item 8. EXHIBITS The Exhibit Index immediately preceding the exhibits is incorporated herein by reference. Item 9. UNDERTAKINGS (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Norwood, Commonwealth of Massachusetts, on this 5th day of December, 2001.

In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, photostatic or other copies, the authenticity of the originals of any such documents and the legal competence of all signatories to such documents. We assume that the appropriate action will be taken, prior to the offer and sale of the shares in accordance with the Plans, to register and qualify the shares for sale under all applicable state securities or "blue sky" laws. We express no opinion herein as to the laws of any state or jurisdiction other than the state laws of The Commonwealth of Massachusetts and the federal laws of the United States of America.

Except where the context otherwise requires, the term "Company" shall include any present or future subsidiaries of Analog Devices, Inc. as defined in Section 424(f) of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the "Code") and any other business venture (including, without limitation, joint venture or limited liability company) in which the Company has a controlling interest, as determined by the Board of Directors of the Company (the "Board"). 2. ELIGIBILITY OF OPTIONEES. All of the Company's employees, consultants and advisors are eligible to be granted options (each, an "Option") under the Plan; PROVIDED, HOWEVER, no Options may be granted under the Plan to any directors of the Company or to any employees who are also officers of the Company as the term "officer" is defined by the Securities and Exchange Commission in Rule 16a-1(f) promulgated under the Securities Exchange Act of 1934, or any successor rule. 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. 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.

STOCK AVAILABLE FOR OPTIONS. Subject to adjustment pursuant to Section 6(a), Options may be granted under the Plan for up to 50,000,000 shares of common stock, $0.16-2/3 par value of the Company ("Common Stock").

Shares issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares. 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. (b) 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"). (c) OPTION AGREEMENT; DURATION OF OPTIONS. Each Option may be evidenced by (i) an Option Agreement in such form and containing such provisions as the Board from time to time shall approve or (ii) a written confirming memorandum to the Optionee setting forth the material terms of the Option.

The Option Agreement may also include, without limitation, provisions relating to (i) subject to the provisions of Section 7, 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 the Plan that the Board shall, in its sole discretion, determine. The terms and conditions of the respective Option Agreements need not be identical. (d) 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 (including electronic notice) approved - 2 -

by the Board together with payment as specified in Section 5(e) for the number of shares for which the Option is exercised. (e) PAYMENT UPON EXERCISE.

(f) SUBSTITUTE OPTIONS. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock, the Board may grant options in substitution for any stock options or other stock or stock-based awards granted by such entity or an affiliate thereof. Substitute Options may be granted on such terms as the Board deems appropriate in the circumstances, notwithstanding any limitations on Options contained in the other sections of this Section 5. 6. ADJUSTMENTS FOR CHANGES IN COMMON STOCK; LIQUIDATION. (a) CHANGES 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 than a normal cash dividend, (i) the number and class of securities available under the Plan and (ii) 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.

(b) EFFECT ON OPTIONS. (1) REORGANIZATION EVENT. Upon the occurrence of a Reorganization 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 a Reorganization 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 if such Reorganization 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, (x) one-half of the number of shares subject to the Option which were not already vested shall be immediately exercisable upon the occurrence of such Reorganization Event, and subject to (y) below, the remaining one-half of such number of shares shall continue to become vested in accordance with the original vesting schedule set forth in such option, with one-half of the number of shares that would otherwise have become vested on each subsequent vesting date in accordance with the original schedule becoming vested on each subsequent vesting date and (y) such assumed or substituted options shall become immediately exercisable in full if, on or prior to the first anniversary of the date of the consummation of the Reorganization 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. For purposes hereof, an Option shall be considered to be assumed if, following consummation of the Reorganization Event, the Option confers the right to purchase, for each share of Common Stock subject to the Option immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the exercise of Options to consist - 6 -

solely of common stock of the acquiring or succeeding corporation (or an affiliate thereof) equivalent in fair market value to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event. 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, upon written notice to the Optionees, provide that all then unexercised Options will become exercisable in full as of a specified time prior to the Reorganization Event and will terminate immediately prior to the consummation of such Reorganization Event, except to the extent exercised by the Optionees before the consummation of such Reorganization Event; PROVIDED, HOWEVER, that in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share of Common Stock surrendered pursuant to such Reorganization Event (the "Acquisition Price"), then the Board may instead provide that all outstanding Options shall terminate upon consummation of such Reorganization Event and that each Optionee shall receive, in exchange therefor, a cash payment equal to the amount (if any) by which (i) the Acquisition Price multiplied by the number of shares of Common Stock subject to such outstanding Options (whether or not then exercisable), exceeds (ii) the aggregate exercise price of such Options. To the extent all or any portion of an Option becomes exercisable solely as a result of the first sentence of this paragraph, upon exercise of such Option the Optionee shall receive shares subject to a right of repurchase by the Company or its successor at the Option exercise price. Such repurchase right shall lapse at the same rate as the Option would have become exercisable under its terms and shall not apply to any shares subject to the Option that were exercisable under its terms without regard to the first sentence of this paragraph. (2) CHANGE IN CONTROL EVENT THAT IS NOT A REORGANIZATION EVENT. Upon the occurrence of a Change in Control Event that does not also constitute a Reorganization 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 shall continue to become vested in accordance with the original vesting schedule set forth in such Option with one-half of the number of shares that would otherwise have become vested on each subsequent vesting date; 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. 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 - 7 -

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; 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 tax 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. (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 and changing the date of exercise or realization, 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 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. - 8 -

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 date on which the Plan was adopted by the Board, but Options previously granted may extend beyond that date. (d) AMENDMENT AND TERMINATION OF PLAN. The Board may amend, suspend or terminate the Plan or any portion thereof at any time. (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.
