Restrictions, if any, imposed upon the transfer of shares:

     Any stockholder, including the heirs, assigns, executors or administrators
of a deceased stockholder, desiring to sell or transfer any stock owned by him
or them, shall first offer it to the corporation through the Board of Directors,
in the manner following:

     He shall notify the directors of his desire to sell or transfer by notice
in writing, which notice shall contain the price at which he is willing to sell
or transfer and the name of one arbitrator.  The Directors shall within thirty
(30) days thereafter either accept the offer, or by notice to him in writing
name a second arbitrator, and these two shall name a third.  It shall then be
the duty of the arbitrators to ascertain the value of the stock, and if any
arbitrator shall neglect or refuse to appear at any meeting appointed by the
arbitrators, a majority may act in the absence of such arbitrator.

     After the acceptance of the offer, or the report of the arbitrators as to
the value of the stock, the directors shall have thirty days within which to
purchase the same at such valuation, but if at the expiration of thirty days,
the corporation shall not have exercised the rights so to purchase, the owner of
the stock shall be at liberty to dispose of the same in any manner he may see
fit.

     No shares of stock shall be sold or transferred on the books of the
corporation until these provisions have been complied with, but the Board of
Directors may in any particular instance waive the requirement.

     We, Ray Stata, President and Paul P. Brountas, Clerk of

                              ANALOG DEVICES, INC.

located at Route 1 Industrial Park, Norwood, MA 02062 do hereby certify that at
a meeting of the directors of the corporation held on September 11, 1980, the
following vote establishing and designating a series of a class of stock and
determining the relative rights and preferences thereof was duly adopted.




   15

                              ANALOG DEVICES, INC.

                          Votes of Board of Directors
                 Creating Series A Convertible Preferred Stock


VOTED:    That pursuant to authority expressly vested in the Board of Directors
          of the Corporation by Article 4 of the Articles of Organization of the
          Corporation, as amended, the Board of Directors hereby authorizes the
          issuance of a series of Preferred Stock, $1.00 par value per share, of
          the Corporation, consisting of 10,000 shares and designated as "Series
          A Convertible Preferred Stock" of the Corporation; and

FURTHER
VOTED:    That the relative rights, preferences, powers, qualifications,
          limitations and restrictions of the Series A Convertible Preferred
          Stock (hereinafter referred to as the "Series A Stock") authorized to
          be issued pursuant to the foregoing vote shall be as follows:

               1.   Dividends.  In each fiscal year of the Corporation the
          holders of shares of Series A Stock shall be entitled to receive,
          before any cash dividends shall be declared and paid upon or set aside
          for the Common stock in such fiscal year, when and as declared by the
          Board of Directors of the Corporation, out of funds legally available
          for that purpose, dividends payable in cash in an amount per share for
          such fiscal year at least equal to the per share amount, if any, of
          any cash dividend for the Common Stock during such fiscal year.  All
          dividends declared upon Series A Stock shall be declared pro rata per
          share.

               2.   Liquidation, Dissolution or Winding Up.  In the event of any
          liquidation, dissolution or winding up of the Corporation, the holders
          of shares of Series A Stock then outstanding shall, unless they elect
          to convert their Series A Stock into Common Stock as set forth in
          Section 4(d) hereof, be entitled to be paid out of the assets of the
          Corporation available for distribution to its stockholders, whether
          from capital, surplus or earnings, before any payment shall be made to
          the holders of any stock ranking on liquidation junior



                                       2A

   16







          to the Series A Stock (with respect to rights on liquidation,
          dissolution or winding up, the Series A Stock shall rank prior to the
          Common Stock) an amount equal to One Thousand Dollars ($1,000) per
          share.  If upon any liquidation, dissolution or winding up of the
          Corporation the assets of the Corporation available for the
          distribution to its stockholders shall be insufficient to pay the
          holders of shares of Series A Stock the full amounts to which they
          respectively shall be entitled, the holders of shares of Series A
          Stock and any class of stock ranking on liquidation on a parity with
          the Series A Stock shall share ratably in any distribution of assets
          according to the respective amounts which would be payable in respect
          of the shares held by them upon such distribution if all amounts
          payable on or with respect to said shares were paid in full.  The
          merger or consolidation of the Corporation into or with another
          corporation, the merger or consolidation of any other corporation into
          or with the Corporation, or the sale, transfer, mortgage, pledge or
          lease of all or substantially all the assets of the Corporation shall
          not be deemed to be a liquidation, dissolution or winding up of the
          Corporation.

               3.   Voting.  The shares of Series A Stock shall have no voting
          rights or power and the holders of such shares shall not be entitled
          to vote such shares upon or in respect of any matter submitted to
          stockholders for vote or action, except (a) as otherwise required by
          law and (b) that the affirmative vote or consent of the holders of
          sixty-six and two-thirds percent (66-2/3%) of the shares of
          outstanding Series A Stock shall be required to authorize any issuance
          of Common Stock or securities convertible into shares of Common Stock
          by the Corporation in a transaction or series of related transactions
          designed to increase the Corporation's equity ownership in an entity
          (or the assets of an entity) in which the Corporation's initial
          investment was funded with the proceeds of the sale of shares of
          Series A Stock and such issuance increases the number of outstanding
          shares of Common Stock on a fully converted basis (treating as
          outstanding for this purpose all common stock equivalents determined
          in accordance with generally accepted accounting principles) by two
          percent (2%) or more.  If any matter is to be submitted to the vote or
          consent of the holders of Series A Stock pursuant to the provisions of
          this Section 3, the



                                       2B


   17


          Corporation shall provide such holders with not less than ten (10)
          days' prior written notice thereof and each share of Series A Stock
          shall be entitled to one vote (in person or by proxy) with respect to
          such matter, voting in the manner provided for in the By-laws of the
          Corporation.

               4.   Conversion.

                    (a)  Shares of Series A Stock may be converted, at the
          option of the holder thereof, in the manner hereinafter provided, into
          fully paid and non-assessable shares of Common Stock of the
          Corporation, at any time during the one-year period (the "Conversion
          Period") commencing (i) on the day ("Conversion Date") which is five
          (5) years from the date of issue of such shares of Series A Stock by
          the Corporation ("Issue Date") and ending (ii) on the day ("Expiration
          Date") which is six (6) years from the Issue Date of such shares of
          Series A Stock.  If any holder of such shares does not elect to
          convert such shares at any time during the Conversion Period, such
          shares shall automatically, without any action on the part of the
          holder thereof, be converted into shares of Common Stock of the
          Corporation on the Expiration Date for such shares of Series A Stock.
          The Series A Stock shall be converted into Common Stock of the
          Corporation during the Conversion Period, whether such conversion is
          voluntary or involuntary, by the Corporation's issuance of that number
          of shares of Common Stock determined by multiplying the number of
          shares of Series A Stock then being converted by a fraction of which
          the numerator shall be $2,000 and the denominator shall be the greater
          of (x) the fair market value per share of Common Stock on the
          Conversion Date or (y) one and one-half (1-1/2) times the book value
          per share of Common Stock, as such book value per share is shown on
          the balance sheet of the Corporation as of the end of the fiscal
          quarter immediately preceding the Conversion Date.  For the purpose
          hereof, "fair market value per share" shall mean the average closing
          price per share of the Common stock of the Corporation on the New York
          Stock Exchange Composite Tape for the sixty (60) day period ending ten
          (10) days prior to the Conversion Date; provided, however, that if the
          Common Stock of the Corporation is not then listed on the New York
          Stock Exchange such fair




                                       2C


   18







          market value shall be the average of the mean between the closing bid
          and asked prices of the Common Stock of the Corporation for such
          60-day period in the over-the-counter market or, if such shares are
          not then traded in the over-the-counter market or any other national
          securities exchange, such fair market value shall be determined by the
          Board of Directors of the Corporation.

                    (b)  In case of any consolidation of the corporation with,
          or merger of the Corporation into, another corporation (other than a
          consolidation or merger in which the Corporation is the continuing
          corporation) or in case of any sale or conveyance to another
          corporation of the assets of the Corporation as an entirety or
          substantially as an entirety, which shall occur while any shares of
          Series A Stock are outstanding, each share of Series A Stock shall
          automatically, without any action on the part of the holder thereof,
          be converted into Common Stock, immediately prior to or
          contemporaneously with such consolidation, merger, sale or conveyance,
          and the holders of Series A Stock shall thereafter be entitled to
          receive, together with all other holders of Common Stock, the kind and
          amount of shares of stock and other securities and property receivable
          upon such consolidation, merger, sale or conveyance by the holders of
          Common Stock.  The conversion of Series A Stock for purposes of this
          paragraph (b) shall be effected by the Corporation's issuance of that
          number of shares of Common Stock determined by multiplying the number
          of shares of Series A Stock then being converted by a fraction of
          which the numerator shall be the sum of $1,000 plus the product of (x)
          $16.66 2/3 multiplied by (y) the number of months (but not in excess
          of sixty (60) months in the aggregate) which elapse during the period
          commencing with the Issue Date and ending as of the end of the month
          immediately preceding the date of such consolidation, merger, sale or
          conveyance, and the denominator shall be the average closing price per
          share of the Common Stock of the Corporation on the New York Stock
          Exchange Composite Tape for the sixty (60) day period ending thirty
          (30) days prior to the date that the Corporation shall have first
          publicly announced the proposed consolidation, merger, sale or
          conveyance; provided, however, that if the Common Stock of the




                                       2D



   19


          Corporation is not then listed on the New York Stock Exchange, such
          per share price shall be determined, on the basis of such 60-day
          period, as set forth in Section 4(a) hereof.

                    (c)  In case any person shall make a tender offer to
          purchase at least fifty-one percent (51%) of the then outstanding
          shares of Common Stock of the Corporation ("Tender Offer") at any time
          while Series A Stock is outstanding, each holder of shares of Series A
          Stock shall have the right, at his election, to convert such shares
          into Common Stock of the Corporation during the period commencing with
          the first public announcement of the Tender Offer ("Offer Date") and
          ending on the date of expiration of the Tender Offer.  If any holder
          elects to so convert his Series A Stock pursuant to this paragraph
          (c), the conversion shall be effected by the Corporation's issuance of
          that number of shares of Common Stock determined by multiplying the
          number of shares of Series A Stock then being converted by a fraction
          of which the numerator shall be the sum of $1,000 plus the product of
          (x) $16.66 2/3 multiplied by (y) the number of months (but not in
          excess of sixty (60) months in the aggregate) which elapse during the
          period commencing with the Issue Date and ending as of the end of the
          month immediately preceding the Offer Date, and the denominator shall
          be the average closing price per share of the Common Stock of the
          Corporation on the new York Stock Exchange Composite Tape for the
          sixty (60) day period ending thirty (30) days prior to the Offer Date;
          provided, however, that if the Common Stock of the Corporation is not
          then listed on the New York Stock Exchange, such per share price shall
          be determined, on the basis of such 60-day period, as set forth in
          Section 4(a) hereof.

                    (d)  In case of any liquidation, dissolution or winding up
          of the Corporation ("liquidation"), whether voluntary or involuntary,
          in lieu of the right to receive the payments specified in Section 2
          hereof, the holders of shares of Series A Stock then outstanding shall
          have the right to convert the Series A Stock into Common Stock, up to
          and until the close of business on the full business day next
          preceding the date fixed for the liquidation of the Corporation, the
          conversion thereof to be effected by the Corporation's issuance of




                                       2E

   20


          that number of shares of Common Stock of the Corporation determined by
          multiplying the number of shares of Series A Stock then being
          converted by a fraction of which the numerator shall be the sum of
          $1,000 plus the product of (x) $16.66 2/3 multiplied by (y) the number
          of months (but not in excess of 60 months in the aggregate) which
          elapse during the period commencing with the Issue Date and ending as
          of the end of the month immediately preceding the date of such
          liquidation, and the denominator shall be the amount (or value if
          other than cash) per share of Common Stock to be distributed to the
          holders of Common Stock in liquidation of the Corporation.

                    (e)  The Corporation shall not issue fractions of shares of
          Common Stock upon conversion of Series A Stock or scrip in lieu
          thereof.  If any fraction of a share of Common Stock would, except for
          the provisions of this paragraph (e), be issuable upon conversion of
          Series A Stock, the Corporation shall in lieu thereof pay to the
          person entitled thereto an amount in cash equal to the current value
          of such fraction, calculated to the nearest one-thousandth (1/1000) of
          a share, to be computed (i) if the Common Stock is listed on any
          national securities exchange on the basis of the last sales price of
          the Common Stock on such exchange (or the quoted closing bid price if
          there shall have been no sales) on the Conversion Date (or Merger
          Date, Offer Date or date of liquidation, as the case may be), or (ii)
          if the Common Stock shall not be so listed, on the basis of the mean
          between the closing bid and asked prices for the Common Stock on the
          Conversion Date (or Merger Date, Offer Date or date of liquidation, as
          the case may be) as reported by NASDAQ, or its successor, and if there
          are no such closing bid and asked prices, on the basis of the fair
          market value per share as determined by the Board of Directors of the
          Corporation.

                    (f)  In order to exercise the conversion privilege, the
          holder of any Series A Stock to be converted shall surrender his or
          its certificate or certificates therefor to the principal office of
          the transfer agent for the Series A Stock (or if no transfer agent be
          at the time appointed, then to the Corporation at its principal
          office), and shall give written notice to the Corporation at such
          office that the holder elects




                                       2F

   21

          to convert the Series A Stock represented by such certificates.  Such
          notice shall also state the name or names (with address) in which the
          certificate or certificates for shares of Common Stock which shall be
          issuable on such conversion shall be issued.  As soon as practicable
          after receipt of such notice and the surrender of the certificate or
          certificates for Series A Stock as aforesaid, the Corporation shall
          cause to be issued and delivered at such office to such holder, or on
          his or its written order, a certificate or certificates for the number
          of full shares of Common Stock issuable on such conversion in
          accordance with the provisions hereof and cash as provided in
          paragraph (e) hereof in respect of any fraction of a share of Common
          Stock otherwise issuable upon such conversion.

                    (g)  On the date that any conversion takes effect hereunder,
          all shares of Series A Stock then to be converted shall cease to have
          any rights with respect to such stock, and the sole rights of the
          holders of such stock shall be with respect to the Common Stock into
          which such shares have been so converted.  Each holder of an
          outstanding certificate of Series A Stock which, prior to conversion
          represented shares of Series A Stock, shall be entitled to receive
          therefor, on and after the date that any such conversion takes effect,
          a certificate or certificates representing the number of shares of
          Common Stock into which such shares shall have been converted, upon
          surrender of such certificate or certificates to such agent or agents
          as may be appointed by the Corporation.  If so required by the
          Corporation, certificates surrendered for conversion shall be endorsed
          or accompanied by a written instrument or instruments of transfer in
          form satisfactory to the Corporation, duly executed by the registered
          holder or by his attorney duly authorized in writing.  All
          certificates evidencing shares of Series A Stock which are required to
          be surrendered for conversion in accordance with the provisions hereof
          shall, from and after the date such certificates are so required to be
          surrendered, be deemed to have been retired and cancelled and the
          shares of Series A Stock represented thereby converted into Common
          Stock for all purposes, notwithstanding the failure of the owner or
          owners thereof to surrender such certificates on or prior to said
          date.

                    (h)  In case:

                         (i)  of any consolidation or merger to which the
          Corporation is a party and for which approval of any stockholders of
          the Corporation is required, or of the sale or transfer of all or
          substantially all of the assets of the Corporation; or

                         (ii) of the involuntary or voluntary dissolution,
          liquidation or winding up of the Corporation;

          then the Corporation shall cause to be filed at the office of the
          transfer agent of the Series A Stock and shall cause to be mailed to
          the holders of the Series A Stock, at their last addresses as they
          shall appear upon the record of such transfer agent at least twenty
          (20) days before the date specified herein below, a notice stating the
          date on which such consolidation, merger, sale, transfer, dissolution,
          liquidation or winding up is expected to become effective, and the
          date as of which it is expected that holders of Common Stock of record
          shall be entitled to exchange their shares of Common Stock for
          securities or other property deliverable upon such consolidation,
          merger, sale, transfer, dissolution, liquidation or winding up.

                    (i)  The Corporation shall use its best efforts, at all
          times when the Series A Stock shall be outstanding, to reserve and
          keep available out of its authorized but unissued stock, for the
          purpose of effecting the conversion of the Series A Stock, such number
          of its duly authorized shares of Common Stock as shall from time to
          time be sufficient to effect the conversion of all outstanding Series
          A Stock.  Before taking any action which would cause an adjustment
          reducing the conversion price below the then par value of the shares
          of Common Stock issuable upon conversion of the Series A Stock, the
          Corporation will take any corporate action which may, in the opinion
          of its counsel, be necessary in order that the Corporation may validly
          and legally issue fully paid and non-assessable shares of such Common
          Stock at such adjusted conversion price.

   23


                    (j)  Upon any such conversion, no adjustment shall be made
          for accrued and unpaid dividends on the Series A Stock surrendered for
          conversion or on the Common Stock delivered.

                    (k)  All shares of Series A Stock which shall have been
          surrendered for conversion as herein provided shall no longer be
          deemed to be outstanding and all rights with respect to such shares,
          including the rights, if any, to receive notices and to vote, shall
          forthwith cease and terminate except only the right of the holders
          thereof to receive Common Stock in exchange therefor.  Any shares of
          Series A Stock so converted shall be retired and cancelled and shall
          not be reissued, and the Corporation may from time to time take such
          appropriate action as may be necessary to reduce the authorized Series
          Stock accordingly.

               5.   Definitions.  The term "Common Stock" shall be deemed to
          refer to the Common Stock, $.16 2/3 par value per share, authorized by
          the Articles of Organization of the Corporation, as amended and in
          effect on the date hereof, and to any additional share of stock of any
          class of the Corporation other than preferred stock with a fixed limit
          on dividends and a fixed amount payable in the event of any voluntary
          or involuntary liquidation, dissolution or winding up of the
          Corporation.

FURTHER
VOTED:    That the President or any Vice Present and the Clerk or an Assistant
          Clerk be and hereby are authorized to execute, on behalf of the
          Corporation and under its corporate seal, a certificate setting forth
          a copy of the foregoing votes, and to cause such certificate to be

          The following is a statement of the designations and the powers,

          The Preferred Stock may be issued in one or more series at such time

may determine.  Each series shall be so designated as to distinguish the shares
thereof from the shares of all other series and classes.  Except as to the
relative rights and preferences referred to in paragraph B below, in respect of
any or all of which there may be variations between different




                                 2A

   58



series, all shares of Preferred Stock shall be identical.  Different series of
Preferred Stock shall not be construed to constitute different classes of shares
for the purpose of voting by classes.

     B.   Authority to Establish Variations Between Series.

          The Board of Directors is expressly authorized, subject to the
limitations prescribed by law and the provisions of these Articles of
Organization, to provide by adopting a vote or votes, a certificate of which
shall be filed in accordance with the Business Corporation Law of the
Commonwealth of Massachusetts for the issue of the Preferred Stock in one or
more series, each with such designations, preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof as shall be stated in the vote or votes creating such
series.  The authority of the Board of Directors with respect to each such
series shall include without limitation of the foregoing the right to determine
and fix:

               (1)  the distinctive designation of such series and the number of
shares to constitute such series;

               (2)  The rate at which dividends on the shares of such series
shall be declared and paid, or set aside for payment, whether dividends at the
rate so determined shall be cumulative, and whether the shares of such series
shall be entitled to any participating or other dividends in addition to
dividends at the rate so determined, and if so on what terms;

               (3)  The right, if any, of the corporation to redeem shares of
the particular series and, if redeemable, the price, terms and manner of such
redemption;

               (4)  The special and relative rights and references, if any, and
the amount of amounts per share, which the shares of such series shall be
entitled to receive upon any voluntary or involuntary liquidation, dissolution
or winding up of the corporation;

               (5)  the terms and conditions, if any, upon which shares of such
series shall be convertible into, or exchangeable for, shares of stock of any
other class or exchangeable for, shares of stock of any other class or classes,
including the price or prices or the rate or rates of conversion or exchange and
the terms of adjustment, if any;




                                2B

   59



               (6)  The obligation, if any, of the corporation to retire or
purchase shares of such series pursuant to a sinking fund or fund of a similar
nature or otherwise, and the terms and conditions of such obligations;

               (7)  Voting rights, if any, provided that the shares of all
series with voting rights shall not have more than one vote per share;

               (8)  limitations, if any, on the issuance of additional shares of
such series or any shares of any other series of Preferred Stock; and

               (9)  Such other preferences or restrictions or qualifications
thereof as the Board of Directors may deem advisable and are not inconsistent
with law and the provisions of these Articles.

     C.   Statement of Limitations, Relative Rights and Powers in Respect of
          Shares of Common Stock.

               (1)  After the requirements with respect to preferential
dividends on the Preferred Stock (fixed in accordance with the provisions of
paragraph 5 above) shall have been met and after the corporation shall have
complied with all the requirements, if any, with respect to the setting aside of
sums as sinking funds or redemption or purchase accounts (fixed in accordance
with the provisions of said paragraph B), then and not otherwise the holders of
Common Stock shall be entitled to receive such dividends as may be declared from
time to time by the Board of Directors.

               (2)  After distribution in full of the preferential amount (fixed
in accordance with the provisions of said paragraph B) to be distributed to the
holders of Preferred Stock in the event of voluntary or involuntary liquidation,
distribution or sale of assets, dissolution or winding up of this corporation,
the holders of the Common Stock shall be entitled to receive all the remaining
assets of this corporation, tangible and intangible, of whatever kind available
for distribution to the stockholders ratably in proportion to the number of
shares of Common Stock held by them respectively.








                                2C

   60







               (3)  Except as may otherwise be required by law or the provisions
of these Articles, or by the Board of Directors pursuant to authority granted in
these Articles, each holder of Common Stock shall have one vote in respect of
each share of stock held by him in all matters voted upon by the stockholders.

     D.   Denial of Preemptive rights.

          No holder of shares of the Common Stock or of the Preferred Stock
shall be entitled as such, as a matter of right, to subscribe for or purchase
any part of any new or additional issue of stock of any class whatsoever of the
corporation, or of securities convertible into stock of any class, whether now
or hereafter authorized, or whether issued for cash or other consideration or by
way of dividend."

     The foregoing amendment will become effective when these articles of
amendment are filed in accordance with the vote adopting the amendment, a later
effective date not more than thirty days after such filing, in which event the
amendment will become effective on such later date.

IN WITNESS WHEREOF AND UNDER THE PENALTIES OF PERJURY, we have hereto signed our

          6A.  INDEMNIFICATION

               Section 1.  Actions, Suits and Proceedings.  Except as otherwise
          provided below, the Corporation shall, to the fullest extent
          authorized by Chapter 156B of the Massachusetts General Laws, as the
          same exists or may hereafter be amended (in the case of any such
          amendment, only to the extent that such amendment either (i) permits
          the Corporation to provide broader indemnification rights than such
          laws permitted prior to such amendment or (ii) prohibits or limits any
          of the indemnification rights previously set forth in such laws),
          indemnify each person who is, or shall have been, a director or
          officer of the Corporation or who is or was a director or employee of
          the Corporation and is serving, or shall have served, at the request
          of the Corporation, as a director or officer of another organization
          or in any capacity with respect to any employee benefit plan of the
          Corporation, against all liabilities and expenses (including
          judgments, fines, penalties, amounts paid or to be paid in settlement,
          and




                                A-1

   79







          reasonable attorneys' fees) imposed upon or incurred by any such
          person (the "Indemnitee") in connection with, or arising out of, the
          defense or disposition of any action, suit or other proceeding,
          whether civil or criminal, in which he may be a defendant or with
          which he may be threatened or otherwise involved, directly or
          indirectly, by reason of his being or having been such a director or
          officer or as a result of his serving or having served with respect to
          any such employee benefit plan; provided, however, that the
          Corporation shall provide no indemnification with respect to any
          matter as to which any such Indemnitee shall be finally adjudicated in
          such action, suit or proceeding not to have acted in good faith in the
          reasonable belief that his action was (i) in the best interests of the
          Corporation or (ii) to the extent such matter relates to service with
          respect to an employee benefit plan, in the best interests of the
          participants or beneficiaries of such employee benefit plan.

                Section 2.  Settlements.  The right to indemnification conferred
          in this Article shall include the right to be paid by the Corporation
          for liabilities and expenses incurred in connection with the
          settlement or compromise of any such action, suit or proceeding,
          pursuant to a consent decree or otherwise, unless a determination is
          made, within 45 days after receipt by the Corporation of a written
          request by the Indemnitee for indemnification, that such settlement or
          compromise is not in the best interests of the Corporation or, to the
          extent such matter relates to service with respect to an employee
          benefit plan, that such settlement or compromise is not in the best
          interests of the participants or beneficiaries of such plan.  Any such
          determination shall be made (i) by the Board of Directors of the
          Corporation by a majority vote of a quorum consisting of disinterested
          directors, or (ii) if such quorum is not obtainable, by a majority of
          the disinterested directors of the Corporation then in office.
          Notwithstanding the foregoing, if there are less than two
          disinterested directors then in office, the Board of Directors shall
          promptly direct that independent legal counsel (who may be regular
          legal counsel to the Corporation) determine, based on facts known to
          such counsel at such time, whether such Indemnitee acted in good faith
          in the reasonable belief




                                      A-2


   80







          that his action was in the best interests of the Corporation or the
          participants or beneficiaries of any such employee benefit plan, as
          the case may be; and, in such event, indemnification shall be made to
          such Indemnitee unless, within 45 days after receipt by the
          Corporation of the request by such Indemnitee for indemnification,
          such independent legal counsel in a written opinion to the Corporation
          determines that such Indemnitee did not act in good faith in the
          reasonable belief that his action was in the best interests of the
          Corporation or the participants or beneficiaries of any such employee
          benefit plan, as the case may be.

                  Section 3.  Notification and Defense of Claim.  As a condition
          precedent to his right to be indemnified, the Indemnitee must give to
          the Corporation notice in writing as soon as practicable of any
          action, suit or proceeding involving him for which indemnity will or
          could be sought.  With respect to any action, suit or proceeding of
          which the Corporation is so notified, the Corporation will be entitled
          to participate therein at its own expense and/or to assume the defense
          thereof at its own expense, with legal counsel reasonably acceptable
          to such Indemnitee.  After notice from the Corporation to the
          Indemnitee of its election so to assume such defense, the Corporation
          shall not be liable to such Indemnitee for any legal or other expenses
          subsequently incurred by such Indemnitee in connection with such
          claim, but the fees and expenses of such counsel incurred after notice
          from the Corporation of its assumption of the defense thereof shall be
          at the expense of the Indemnitee unless (i) the employment of counsel
          by the Indemnitee has been authorized by the Corporation, (ii) counsel
          to the Indemnitee shall have reasonably concluded that there may be a
          conflict of interest or position on any significant issue between the
          Corporation and the Indemnitee in the conduct of the defense of such
          action or (iii) the Corporation shall not in fact have employed
          counsel to assume the defense of such action, in each of which cases,
          the fees and expenses of counsel for the Indemnitee shall be at the
          expense of the Corporation, except as otherwise expressly provided by
          this Article.  The Corporation shall not be entitled to assume the
          defense of any claim brought by or on behalf of the Corporation or as
          to which counsel for the Indemnitee shall have reasonably made the
          conclusion provided for in (ii) above.

                  Section 4.  Advance of Expenses.  Subject to Section 3 above,
          the right to indemnification conferred in this Article shall include
          the right to be paid by the Corporation for expenses (including
          reasonable attorneys' fees) incurred in defending a civil or criminal
          action, suit or proceeding in advance of its final disposition,
          subject to receipt of an undertaking by the Indemnitee to repay such
          payment if it is ultimately determined that the Indemnitee is not
          entitled to indemnification under this Article.  Such undertaking may
          be accepted without reference to the financial ability of such
          Indemnitee to make such repayment. Notwithstanding the foregoing, no
          advance shall be made by the Corporation under this Section 4 if a
          determination is reasonably and promptly made by the Board of
          Directors 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 Corporation then in office or, if there
          are not at least two disinterested directors then in office, by
          independent legal counsel (who may be regular legal counsel to the
          Corporation) in a written opinion that, based on facts known to the
          Board or counsel at such time, such Indemnitee did not act in good
          faith in the reasonable belief that his action was in the best
          interests of the Corporation or the participants or beneficiaries of
          an employee benefit plan of the Corporation, as the case may be.

                  Section 5.  Partial Indemnity.  If an Indemnitee is entitled
          under any provision of this Article to indemnification by the
          Corporation for some or a portion of the liabilities or expenses
          imposed upon or incurred by such indemnitee in the investigation,
          defense, appeal or settlement of any action, suit or proceeding but
          not, however, for the total amount thereof, the Corporation shall
          nevertheless indemnify the Indemnitee for the portion of such
          liabilities or expenses to which such Indemnitee is entitled.

                  Section 6.  Rights Not Exclusive.  The right to
          indemnification and the payment of expenses incurred in defending any
          action, suit or proceeding in advance of its final disposition
          conferred in this Article shall not be exclusive of any other right

          vote of stockholders or directors or otherwise.  Without limiting the
          generality of the foregoing, the Corporation, acting through its Board
          of Directors, may enter into agreements with any director, officer,
          employee or agent of the Corporation providing for indemnification
          rights equivalent to or greater than the indemnification rights set
          forth in this Article.

                   Section 7.  Insurance.  The Corporation may purchase and
          maintain insurance, at its expense, to protect itself and any
          director, officer, employee or agent of the Corporation or another
          organization or employee benefit plan against any expense or liability
          incurred by him in any such capacity, or arising out of the status as
          such, whether or not the Corporation would have the power to indemnify
          such person against such expense or liability under Chapter 156B of
          the Massachusetts General Laws.

                   Section 8.  Insurance Offset.  The Corporation's obligation
          to provide indemnification under this Article shall be offset to the
          extent of any other source of indemnification or any otherwise
          applicable insurance coverage under a policy maintained by the
          Corporation or any other person.

                   Section 9.  Amendment.  Without the consent of a person
          entitled to the indemnification and other rights provided in this
          Article (unless otherwise required by Chapter 156B of the
          Massachusetts General Laws), no amendment modifying or terminating
          such rights shall adversely affect such person's rights under this
          Article with respect to the period prior to such Amendment.

                   Section 10.  Mergers, Etc.  If the Corporation is merged into
          or consolidated with another corporation and the Corporation is not
          the surviving corporation, or if substantially all of the assets of
          the Corporation are acquired by any other corporation, or in the event
          of any other similar reorganization involving the Corporation, the
          Board of Directors of the Corporation or the board of directors of any
          corporation assuming the obligations of the Corporation shall assume
          the obligations of the Corporation under this Article, through the
          date of such merger, consolidation, sale or





                                      A-5

   83







          reorganization, with respect to each person who is entitled to
          indemnification rights under this Article as of such date.

               Section 11.  Savings Clause.  If this Article or any portion
          hereof shall be invalidated on any ground by any court of competent
          jurisdiction, then the Corporation shall nevertheless indemnify each
          Indemnitee as to any liabilities and expenses with respect to any
          action, suit or proceeding to the full extent permitted by any
          applicable portion of this Article that shall not have been
          invalidated and to the full extent permitted by applicable law.

               Section 12.  Definitions.  As used in this Article, the term
          "director", "officer" and "person" include their respective heirs,
          executors, administrators, and legal representatives, and an
          "interested" director is one against whom in such capacity the
          proceedings in question or another proceeding on the same or similar
          grounds is then pending.

FURTHER
VOTED:    That Article 6 of the Articles of Organization of the Corporation
          shall be amended by adding new Article 6D, to read as follows:

          6D.  LIMITATION OF DIRECTOR LIABILITY

               To the fullest extent permitted by Chapter 156B of the
          Massachusetts General Laws, as it may be amended from time to time, a
          director of the Corporation shall not be personally liable to the
          Corporation or its stockholders for monetary damages for breach of
          fiduciary duty as a director, notwithstanding any provision of law
          imposing such liability.
