     Item 1.  Description of Registrant's Securities to be Registered.

               On December 7, 1994, the United States District
     Court for the District of Massachusetts approved a set
     tlement ("Settlement") entered into between Unitrode
     Corporation (the "Company") and plaintiffs in a certain
     purported class action lawsuit entitled Steiner vs.
     Unitrode Corporation, et al., Civil Action No. 90-11443
     (MLW).  Pursuant to the Settlement, the Company agreed to
     issue and distribute, pursuant to a Stipulation of Set
     tlement (the "Stipulation") made and entered into as of
     August 17, 1994, warrants (the "Warrants") to purchase
     fully paid and non-assessable shares of the Common Stock,
     par value $.20 per share ("Common Stock"), of the
     Company.  In accordance with the provisions of the
     Stipulation, 247,883 Warrants representing the right to
     acquire  247,883 shares of Common Stock at an initial
     exercise price of $28.467 per Warrant are being issued
     pursuant to the Settlement and Stipulation.  The Warrants
     are expected to be listed on The Nasdaq SmallCap Market.

               The terms and conditions of the Warrants are
     set out in a Warrant Agreement to be entered into by the
     Company and The First National Bank of Boston, as Warrant
     Agent, the form of which is attached hereto as Exhibit 1
     (the "Warrant Agreement"), and the Warrants are
     represented by a Warrant Certificate, a form of which is
     attached to the Warrant Agreement.  The following is a
     general description of the terms and conditions of the
     Warrants and Warrant Agreement and is qualified in its
     entirety by reference to the provisions of the Warrant
     Agreement and form of Warrant Certificate which are
     attached hereto as Exhibit 1 and which are incorporated
     by reference herein.

               The Warrant Agreement provides for the issuance
     of 247,883 Warrants, each representing initially the
     right to acquire upon exercise one share of Common Stock
     at an exercise price of $28.467 per Warrant.  The
     Warrants are exercisable for a period of one year,
     commencing on August 21, 1996 and ending at 5:00 p.m.,
     New York City time, on August 21, 1997.  The exercise
     price and/or the securities issuable upon exercise are
     subject to adjustment as set forth in the Warrant
     Agreement to account for payment by the Company of stock
     dividends payable in shares of Common Stock,
     subdivisions, combinations and reclassifications of the
     Common Stock into a greater or lesser number of shares,
     mergers, consolidations or acquisitions of the Company
     with or into another company, and the acquisition of all
     the outstanding Common Stock by any person or company. 
     The Warrants permit the Company to make additional
     reductions in the exercise price so that any event
     treated for federal income tax purposes as a dividend of
     stock or stock rights shall not be taxable to the
     recipients.

                                                            EXHIBIT 1

                              WARRANT AGREEMENT

                    WARRANT AGREEMENT, between UNITRODE
          CORPORATION, a Maryland Corporation (the "Company"), and
          THE FIRST NATIONAL BANK OF BOSTON (the "Warrant Agent").

                    WHEREAS, the Company proposes to issue Common
          Stock Subscription Warrants, as hereinafter described
          (the "Warrants"), to purchase up to an aggregate of
          247,883 fully paid and nonassessable shares of its Common
          Stock, par value $.20 per share ("Common Stock", and the
          shares of Common Stock issuable upon exercise of the
          Warrants being referred to herein as the "Warrant
          Shares"), each Warrant entitling the holder thereof to
          purchase one share of Common Stock at an Exercise Price
          (defined in Section 9 hereof) of $28.467 per Warrant,
          subject to adjustment as hereinafter provided; and

                    WHEREAS, the Company desires the Warrant Agent
          to act on behalf of the Company, and the Warrant Agent is
          willing so to act, in connection with the issuance of the
          Warrants and the other matters as provided herein.

                    NOW, THEREFORE, in consideration of the
          foregoing and for the purpose of defining the terms and
          provisions of the Warrants and the respective rights and
          obligations thereunder of the Company and the registered
          holders of the Warrants (the "Holders"), the Company and
          the Warrant Agent hereby agree as follows:

                    SECTION 1.  Appointment of Warrant Agent.  The
          Company hereby appoints the Warrant Agent to act as agent
          for the Company in accordance with the provisions
          hereinafter set forth in this Agreement, and the Warrant
          Agent hereby accepts such appointment.  As used herein,
          the term "Warrant Agent" shall mean the Warrant Agent and
          any successor appointed hereunder.

                    SECTION 2.  Form and Countersignature of
          Warrants.

                    2.1  Form of Warrant.  The text of the Warrant,
          the subscription form (the "Subscription Form"), and form
          of assignment shall be substantially as set forth in
          Exhibit A attached hereto.  The Warrants shall be
          executed on behalf of the Company by one or more
          authorized officers.  The signature of any such officers
          on the Warrants may be made manually or by facsimile.

                    2.2  Countersignature of Warrants.  The
          Warrants shall be countersigned manually or by facsimile
          by the Warrant Agent and shall not be valid for any
          purpose unless so countersigned.  Warrants may be
          countersigned by the Warrant Agent and may be issued or
          delivered by the Warrant Agent, notwithstanding that the
          persons whose manual or facsimile signatures appear
          thereon as proper officers of the Company shall have
          ceased to be such officers at the time of such
          countersignature, issuance or delivery.  Warrants shall
          be dated as of the date of issuance or countersignature
          thereof by the Warrant Agent either upon initial issuance
          or upon exchange, substitution or transfer.

                    SECTION 3.  Issuance and Registration of Warrants.

                    3.1  Initial Issuance of Warrants.  The Warrant
          Agent shall issue the Warrants upon receipt of, and in
          accordance with, a statement from an authorized
          representative of the Company as contemplated by Section
          15.10 hereof specifying the identity of, and number of
          Warrants to be issued to, each person or entity to be
          issued Warrants.

                    3.2  Registration.  The Warrants shall be
          numbered and shall be registered in a warrant register
          maintained by the Warrant Agent as they are issued.  The
          Company and the Warrant Agent may deem and treat the
          registered holder of a Warrant Certificate as the
          absolute owner thereof (notwithstanding any notation of
          ownership or other writing thereon made by anyone), for
          the purpose of any exercise or conversion thereof and any
          distribution to the holder thereof and for all other
          purposes and neither the Company nor the Warrant Agent
          shall be affected by any notice to the contrary.  The
          Company shall not be bound to recognize any equitable or
          other claim to or interest in such Warrant on the part of
          any other person.

                    SECTION 4.  Transfer and Exchange of Warrants. 

                    4.1  Transfer of Warrants.  The Warrants shall
          be transferable only on the books of the Warrant Agent
          maintained at the office of the Warrant Agent designated
          for such purpose upon delivery thereof duly endorsed by
          the Holder or by his duly authorized attorney-in-fact or
          representative, or accompanied by proper evidence of
          succession, assignment or authority to transfer, which
          endorsement shall be guaranteed by an eligible guarantor
          institution which is a member of a signature guarantee
          program satisfactory to the Warrant Agent (an "Eligible
          Institution").  Warrants may be transferred only in
          whole, so as to allow the Holder of each Warrant to
          purchase one full share of Common Stock.  In all cases of
          transfer by an attorney-in-fact, the original power of
          attorney, duly approved, or a copy thereof, duly
          certified, in such form and with such other evidence of
          authority as the Warrant Agent shall request, shall be
          deposited and remain with the Warrant Agent.  In case of
          transfer by executors, administrators, guardians or other
          legal representatives, duly authenticated evidence of
          their authority shall be produced, in such form and with
          such other evidence of authority as the Warrant Agent
          shall request, and may be required to be deposited and
          remain with the Warrant Agent in its discretion.  Upon
          any such registration of transfer, the Warrant Agent
          shall countersign and deliver a new Warrant or Warrants
          to the person entitled thereto. 
           
                    4.2  Exchange of Warrant Certificates.  Each
          Warrant certificate may be exchanged upon surrender at
          the office of the Warrant Agent designated for such
          purpose for another certificate or certificates entitling
          the Holder thereof to purchase a like aggregate number of
          Warrant Shares as the certificate or certificates
          surrendered then entitle such Holder to purchase.  Any
          Holder desiring to exchange a Warrant certificate or
          certificates shall make such request in writing delivered
          to the Warrant Agent, and shall surrender, properly
          endorsed, the certificate or certificates to be so
          exchanged.  Thereupon, the Warrant Agent shall
          countersign and deliver to the Holder a new Warrant
          certificate or certificates, as the case may be, as so
          requested, in the name of such Holder.  No fractional
          Warrant certificates shall be issued and no new Warrant
          certificate entitling the Holder thereof to purchase
          fractional shares will be issued.

                    SECTION 5.  Term of Warrants; Exercise of Warrants.

                    5.1  Term of Warrants.  Subject to the terms of
          this Agreement, each Holder shall have the right, which
          may be exercised commencing at the opening of business on
          August 21, 1996 until 5:00 p.m., New York time, on August
          21, 1997 (the "Expiration Date"), to purchase from the
          Company the number of fully paid and nonassessable
          Warrant Shares which the Holder may at the time be
          entitled to purchase on exercise of such Warrants.

                    5.2  Exercise of Warrants.  A Warrant may be
          exercised upon surrender to the Warrant Agent at its
          office designated for such purpose of the certificate or
          certificates evidencing the Warrants to be exercised,
          together with the Subscription Form duly completed and
          signed, which signature shall be guaranteed by an
          Eligible Institution, and upon payment to the Warrant
          Agent for the account of the Company of the Exercise
          Price (as defined in Section 9 hereof and subject to
          adjustment in accordance with the provisions of Section
          10 hereof) for the number of Warrant Shares in respect of
          which such Warrants are then exercised.  Payment of the
          aggregate Exercise Price shall be made by certified or
          official bank check.

                    Subject to Section 6 hereof, upon the surrender
          of Warrants and payment of the Exercise Price as
          aforesaid, the Warrant Agent shall cause to be issued and
          delivered as soon as practicable to or upon the written
          order of the Holder and in such name or names as the
          Holder may designate, a certificate or certificates for
          the number of full Warrant Shares so purchased upon the
          exercise of such Warrants.  If permitted by applicable
          law, such certificate or certificates shall be deemed to
          have been issued and any person so designated to be named
          therein shall be deemed to have become a holder of record
          of such Warrant Shares as of the date of the receipt by
          the Warrant Agent of such Warrants and payment of the
          Exercise Price, as aforesaid; provided, however, that if
          at the date of surrender of such Warrants and payment of
          such Exercise Price, the transfer books for the shares of
          Common Stock purchasable upon the exercise of such
          Warrants shall be closed, the certificates for the shares
          in respect of which such Warrants are then exercised
          shall be issuable as of the date on which such books
          shall be opened, and until such date the Company shall be
          under no duty to deliver any certificate for such shares
          and the holder of the Warrant shall not be deemed to be
          the holder of shares of Common Stock issuable upon
          exercise of such Warrant until such time as such books
          shall be opened; provided, further, however, that such
          transfer books, unless otherwise required by law or by
          applicable rule of any national securities exchange,
          shall not be closed at any one time for a period longer
          than twenty (20) days.  The rights of purchase
          represented by the Warrants shall be exercisable, at the
          election of the Holders thereof, either in full or from
          time to time in part, and in the event that a certificate
          evidencing Warrants is exercised in respect of less than
          all of the Warrant Shares purchasable on such exercise at
          any time prior to the date of expiration of the Warrants,
          a new certificate evidencing the remaining Warrant or
          Warrants will be issued to the Holder thereof, and the
          Warrant Agent is hereby authorized to countersign and
          deliver the required new Warrant certificate or
          certificates pursuant to the provisions of this Section
          and Section 2 hereof.

                    5.3  Compliance with Government Regulations. 
          The Company covenants that if any shares of Common Stock
          required to be reserved for purposes of exercise of
          Warrants require, under any federal securities law or
          applicable governing rule or regulation of any national
          securities exchange, registration with or approval of any
          governmental authority, or listing on any such national
          securities exchange before such shares may be issued upon
          exercise, the Company will in good faith prior to the
          issuance of such shares endeavor to cause such shares to
          be duly registered, approved or listed on the relevant
          national securities exchange, as the case may be;
          provided, however, that in no event shall such shares of
          Common Stock be issued, and the Company is hereby
          authorized to suspend the exercise of all Warrants, for
          the period during which such registration, approval or
          listing is required but not in effect.  The Company
          covenants that it will use reasonable efforts to obtain
          any required approvals or registration under state "blue
          sky" securities laws for the issuance of the Warrant
          Shares; provided, however, that Warrants may not be
          exercised by, or Warrant Shares issued to, any Holder in
          any state where such exercise or issuance would be
          unlawful.

                    SECTION 6.  Payment of Taxes.  The Company will
          pay all documentary stamp taxes, if any, attributable to
          the initial issuance of Warrant Shares upon the exercise
          of Warrants; provided, however, that the Company shall
          not be required to pay any tax or taxes which may be
          payable in respect of any transfer involved in the issue
          or delivery of any Warrants or certificates for Warrant
          Shares in a name other than that of the Holder of such
          Warrants, and the Company shall not be required to issue
          or deliver such Warrants or certificates for Warrant
          Shares or proceeds unless or until the person or persons
          requesting the issuance thereof shall have paid to the
          Company the amount of such tax or shall have established
          to the satisfaction of the Company that such tax has been
          paid.

                    SECTION 7.  Mutilated or Missing Warrants.  In
          case any of the certificates evidencing the Warrants
          shall be mutilated, lost, stolen or destroyed, the
          Company may in its discretion issue, and the Warrant
          Agent shall countersign and deliver in exchange and
          substitution for and upon cancellation of the mutilated
          Warrant certificate, or in lieu of and in substitution
          for the Warrant certificate lost, stolen or destroyed, a
          new Warrant certificate of like tenor and representing an
          equivalent right or interest, but only upon receipt of
          evidence satisfactory to the Company and the Warrant
          Agent of such loss, theft or destruction of such Warrant
          and an indemnity or bond, if requested, also satisfactory
          to them.  An applicant for such a substitute Warrant
          certificate shall also comply with such other reasonable
          regulations and pay such other reasonable charges as the
          Company or the Warrant Agent may prescribe.

                    SECTION 8.  Reservation of Warrant Shares;
          Purchase and Cancellation of Warrants.

                    8.1  Reservation of Warrant Shares.  There have
          been reserved, and the Company shall at all times keep
          reserved, out of its authorized Common Stock, a number of
          shares of Common Stock sufficient to provide for the
          exercise of the rights of purchase represented by the
          outstanding Warrants.  The transfer agent for the Common
          Stock (the "Transfer Agent") and every subsequent
          transfer agent for any shares of the Company's capital
          stock issuable upon the exercise of any of the rights of
          purchase aforesaid will be authorized and directed at all
          times to reserve such number of authorized shares as
          shall be required for such purpose.  The Company will
          keep a copy of this Agreement on file with the Transfer
          Agent and with every subsequent transfer agent for any
          shares of the Company's capital stock issuable upon the
          exercise of the rights of purchase represented by the
          Warrants.  The Warrant Agent is hereby authorized to
          requisition from time to time from the Transfer Agent the
          stock certificates required to honor outstanding Warrants
          upon exercise thereof in accordance with the terms of
          this Agreement.  The Company will supply the Transfer
          Agent and any such subsequent transfer agent with duly
          executed stock certificates for such purposes.  The
          Company will furnish the Transfer Agent and any such
          subsequent transfer agent a copy of all notices of
          adjustments delivered by the Company to the Warrant Agent
          hereunder. 

                    8.2  Purchase of Warrants by the Company.  The
          Company shall have the right, except as limited by law,
          other agreements or herein, to purchase or otherwise
          acquire Warrants at such times, in such manner and for
          such consideration as it may deem appropriate.

                    8.3  Cancellation of Warrants.  In the event
          the Company shall purchase or otherwise acquire Warrants,
          the same shall thereupon be delivered to the Warrant
          Agent and be cancelled by it and retired.  The Warrant
          Agent shall cancel any Warrant surrendered for exchange,
          substitution, transfer or exercise in whole or in part
          and such cancelled Warrant Certificate shall be disposed
          of by the Warrant Agent in a manner satisfactory to the
          Company.

                    SECTION 9.  Exercise Price.  The price per
          share at which a Warrant Share shall be purchasable upon
          exercise of a Warrant (the "Exercise Price") shall be
          $28.467, subject to adjustment as provided in Section 10
          hereof.

                    SECTION 10.  Adjustments.  The Exercise Price
          and the number and kind of securities subject to purchase
          upon the exercise of each Warrant shall be subject to
          adjustment from time to time upon the happening of
          certain events, as hereinafter set forth.

                    10.1  Adjustments.  (a)  In the event that,
          prior to the Expiration Date, the Company shall (i)
          declare a dividend or make a distribution on its shares
          of Common Stock payable in shares of Common Stock, (ii)
          subdivide or reclassify the outstanding Common Stock into
          a greater number of shares of Common Stock, or (iii)
          combine or reclassify the outstanding Common Stock into a
          smaller number of shares of Common Stock, the Exercise
          Price in effect and number of Warrant Shares which are to
          be issued upon exercise of a Warrant at the time of the
          record date for such dividend or of the effective date of
          such subdivision, combination or reclassification, shall
          be proportionately adjusted so that the holder of any
          Warrant exercised after such time shall be entitled to
          receive the aggregate number of shares of Common Stock
          which, if such Warrant had been exercised immediately
          prior to such date, he would have owned upon such
          exercise and been entitled to receive by virtue of such
          dividend, distribution, subdivision, combination or
          reclassification.  Such adjustment shall be made
          successively whenever any event listed above shall occur.

                         (b)  In the event, prior to the Expiration
          Date, of any merger or consolidation of the Company with
          or into, or all of the outstanding Common Stock is
          acquired by, any other person or company, the Holder of
          Warrants shall receive upon such exercise of the Warrants
          and payment of the Exercise Price the kind and amount of
          shares of stock and other securities and property
          (including cash) receivable upon such merger,
          consolidation or acquisition, by a Holder of the number
          of shares of Common Stock into which such Warrants so
          exercised might have been exercised immediately prior to
          such merger, consolidation or acquisition, subject to
          adjustments which, for events subsequent to the effective
          date of such merger, consolidation or acquisition, shall
          be on terms as nearly equivalent as practicable to the
          adjustments provided above.  The above provisions shall
          similarly apply to successive mergers and consolidations.

                         (c)  The Company may make such reduction
          in the Exercise Price, in addition to those required by
          clauses (a) or (b) of this Section 10.1, as it considers
          to be advisable in order that any event treated for
          federal income tax purposes as a dividend of stock or
          stock rights shall not be taxable to the recipients.

                         (d)  Notwithstanding anything to the
          contrary contained in this Section 10.1, no adjustment in
          the Exercise Price shall be required unless such
          adjustments would require an increase or decrease of at
          least one per cent in such price; provided, however, that
          any adjustments which by reason of this Section 10.1(d)
          are not required to be made shall be carried forward and
          taken into account in any subsequent adjustment.  All
          calculations under this Section 10.1 shall be made to the
          nearest cent.

                         (e)  In any case in which this Section
          10.1 shall require that any adjustment in the Exercise
          Price be made effective as of immediately after a record
          date for a specified event, the Company may elect to
          defer until the occurrence of the event the issuing to
          the Holder of any Warrant exercised after that record
          date of the shares of Common Stock and other capital
          stock of the Company, if any, issuable upon the exercise
          over and above the shares of Common Stock and other
          capital stock of the Company, if any, issuable upon the
          exercise on the basis of the Exercise Price in effect
          prior to such adjustment; provided, however, that the
          Company shall deliver to the Holder a due bill or other
          appropriate instrument evidencing the Holder's right to
          receive such additional shares upon the occurrence of the
          event requiring such adjustment.

                         (f)  Notwithstanding anything to the
          contrary contained in this Section 10.1, no adjustment to
          the Exercise Price or other terms of the Warrants need be
          made if Holders are to participate in any transaction on
          a basis, and with notice, that the Board of Directors of
          the Company determines to be fair and appropriate in
          light of the basis and notice on which holders of Common
          Stock participate in the transaction.

                    10.2  Notice of Adjustment.  Whenever the
          Exercise Price is adjusted, as herein provided, the
          Company shall cause the Warrant Agent promptly to give
          notice to the Holders as provided in Section 18 hereof of
          such adjustment or adjustments and shall deliver to the
          Warrant Agent a certificate setting forth the Exercise
          Price after such adjustment, setting forth a brief
          statement of the facts requiring such adjustment and
          setting forth the computation by which such adjustment
          was made.  Such certificate shall be conclusive evidence
          of the correctness of such adjustment.  The Warrant Agent
          shall be entitled to rely on such certificate and shall
          be under no duty or responsibility with respect to any
          such certificate, except to exhibit the same, from time
          to time, to any Holder desiring an inspection thereof
          during normal business hours.  The Warrant Agent shall
          not at any time be under any duty or responsibility to
          any Holders to determine whether any facts exist which
          may require any adjustment of the Exercise Price or other
          stock or property purchasable on the exercise thereof, or
          with respect to the nature or extent of any such
          adjustment when made, or with respect to the method
          employed in making such adjustment.

                    10.3  Statement on Warrants.  Irrespective of
          any adjustments in the Exercise Price or the number or
          kind of shares or other property purchasable upon the
          exercise of the Warrants or other amendments to or
          corrections of this Agreement, Warrants theretofore or
          thereafter issued may continue to express the same price
          and number and kind of shares as are stated in the
          Warrants initially issuable pursuant to this Agreement.

                    SECTION 11.  No Fractional Interests.  No
          Warrant entitling the Holder to purchase fractional
          interests in Warrant Shares and no fractional Warrant
          Shares, or cash or other consideration in lieu thereof,
          will be issued.

                    SECTION 12.  No Rights as Stockholders; Notice
          to Holders.  Nothing contained in this Agreement or in
          any of the Warrants shall be construed as conferring upon
          the Holders or their transferees the right to vote or to
          receive dividends or to consent or to receive notice as
          stockholders in respect of any meeting of stockholders
          for the election of directors of the Company or any other
          matter, or any rights whatsoever as stockholders of the
          Company.  If, however, at any time during which the
          Warrants are exercisable and prior to their exercise, any
          of the following events shall occur:

                         (a)  the Company shall declare any
          dividend or distribution payable in any securities (other
          than any dividend or distribution of securities pursuant
          to the Rights Agreement dated as of May 2, 1990, as
          thereafter amended, between the Company and The First
          National Bank of Boston, as Rights Agent, or pursuant to
          any similar agreement) to all holders of its shares of
          Common Stock; or

                         (b)  a dissolution, liquidation or winding
          up of the Company shall be proposed;

          then in any one or more of said events, the Company shall
          give notice in writing of such event to the Warrant Agent
          and the Warrant Agent shall give notice to the Holders as
          provided in Section 18 hereof, such giving of notice to
          the Warrant Agent to be completed at least 10 days prior
          to the date fixed as a record date or the date of closing
          the transfer books for the determination of the
          stockholders entitled to such dividend or distribution or
          for the determination of stockholders entitled to vote on
          such proposed action.  Such notice shall specify such
          record date or the date of closing the transfer books, as
          the case may be.  Failure to mail or receive such notice
          or any defect therein or in the mailing thereof shall not
          affect the validity of any action taken in connection
          with such dividend or distribution or action.

                    SECTION 13.  Disposition of Proceeds on
          Exercise of Warrants; Inspection of Warrants Agreement. 
          The Warrant Agent shall account promptly to the Company
          with respect to Warrants exercised and concurrently pay
          to the Company all monies received by the Warrant Agent
          for the purchase of the Warrant Shares through the
          exercise of such Warrants.

                    The Warrant Agent shall keep copies of this
          Agreement and any notices given or received hereunder
          available for inspection by the Holders during normal
          business hours at its office designated for such purpose. 
          The Company shall supply the Warrant Agent from time to
          time with such number of copies of this Agreement as the
          Warrant Agent may request.

                    SECTION 14.  Merger or Consolidation or Change
          of Name of Warrant Agent.  Any corporation into which the
          Warrant Agent may be merged or with which it may be
          consolidated, or any corporation resulting from any
          merger or consolidation to which the Warrant Agent shall
          be a party, or any corporation succeeding to
          substantially all of the business of the Warrant Agent,
          shall be the successor to the Warrant Agent hereunder
          without the execution or filing of any paper or any
          further act on the part of any of the parties hereto,
          provided that such corporation would be eligible for
          appointment as a successor Warrant Agent under the
          provisions of Section 16 hereof.  In case at the time
          such successor to the Warrant Agent shall succeed to the
          agency created by this Agreement any of the Warrants
          shall have been countersigned but not delivered, any such
          successor to the Warrant Agent may adopt the
          countersignature of the original Warrant Agent and
          deliver such Warrants so countersigned and in case at
          that time any of the Warrants shall not have been
          countersigned; any successor to the Warrant Agent may
          countersign such Warrants either in the name of the
          predecessor Warrant Agent or in the name of the successor
          Warrant Agent; and in any such cases such Warrants shall
          have the full force provided in the Warrants and in this
          Agreement.

                    In case at any time the name of the Warrant
          Agent shall be changed and at such time any of the
          Warrants shall have been countersigned but not delivered,
          the Warrant Agent may adopt the countersignatures under
          its prior name and deliver such Warrants so countersigned
          and in case at that time any of the Warrants shall not
          have been countersigned; the Warrant Agent may
          countersign such Warrants either in its prior name or in
          its changed name; and in all such cases such Warrants
          shall have the full force provided in the Warrants and in
          this Agreement.

                    SECTION 15.  Concerning the Warrant Agent.  The
          Warrant Agent undertakes the duties and obligations
          imposed by this Agreement upon the following terms and
          conditions, by all of which the Company and the Holders,
          by their acceptance of Warrants, shall be bound.

                    15.1  Correctness of Statements.  The
          statements contained herein and in the Warrants shall be
          taken as statements of the Company and the Warrant Agent
          assumes no responsibility for the correctness of any of
          the same except such as describe the Warrant Agent or
          action taken by it.  The Warrant Agent assumes no
          responsibility with respect to the distribution of the
          Warrants except as otherwise provided herein.

                    15.2  Breach of Covenants.  The Warrant Agent
          shall not be responsible for any failure of the Company
          to comply with any of the covenants of the Company
          contained in this Agreement or in the Warrant.

                    15.3  Reliance on Counsel.  The Warrant Agent
          may consult at any time with legal counsel satisfactory
          to it (who may be counsel for the Company) and the
          Warrant Agent shall incur no liability or responsibility
          to the Company or to any Holder in respect of any action
          taken, suffered or omitted by it hereunder in good faith
          and in accordance with the opinion or the advice of such
          counsel.

                    15.4  Proof of Actions Taken.  Whenever in the
          performance of its duties under this Agreement the
          Warrant Agent shall deem it necessary or desirable that
          any fact or matter be proved or established by the
          Company prior to taking or suffering any action
          hereunder, such fact or matter (unless other evidence in
          respect thereof be herein specifically prescribed) may be
          deemed conclusively to be proved and established by a
          certificate signed by an officer of the Company and
          delivered to the Warrant Agent; and such certificate
          shall be full authorization to the Warrant Agent for any
          action taken or suffered in good faith by it under the
          provisions of this Agreement in reliance upon such
          certificate.

                    15.5  Compensation and Indemnification.  The
          Company agrees to pay the Warrant Agent reasonable
          compensation for all services rendered by the Warrant
          Agent in the performance of its duties under this
          Agreement, to reimburse the Warrant Agent for all
          expenses, taxes and governmental charges and other
          charges of any kind and nature reasonably incurred by the
          Warrant Agent in the performance of its duties under this
          Agreement, and to indemnify the Warrant Agent and save it
          harmless against any and all liabilities, including
          judgments, costs and reasonable counsel fees and
          expenses, for anything done or omitted by the Warrant
          Agent in the performance of its duties under this
          Agreement except as a result of the Warrant Agent's gross
          negligence, willful misconduct or bad faith.  In
          connection with such indemnification, the Company shall
          be entitled to conduct any litigation and shall only be
          required to pay the reasonable costs and fees of one
          counsel selected by the Company.  The Warrant Agent will
          cooperate in the defense of any such action and will not
          settle such action without the consent of the Company.

                    15.6  Other Transactions in Securities of
          Company.  The Warrant Agent and any stockholder,
          director, officer or employee of the Warrant Agent may
          buy, sell or deal in any of the Warrants or other
          securities of the Company or become pecuniarily
          interested in any transaction in which the Company may be
          interested or contract with or lend money to the Company
          or otherwise act as fully and freely as though the
          Warrant Agent was not Warrant Agent under this Agreement. 
          Nothing herein shall preclude the Warrant Agent from
          acting in any other capacity for the Company or for any
          legal entity including, without limitation, acting as a
          lender to the Company or an affiliate thereof.

                    15.7  Liability of Warrant Agent. The Warrant
          Agent shall act hereunder solely as the agent of the
          Company and its duties shall be determined solely by the
          provisions hereof.  The Warrant Agent shall not be liable
          for anything which it may do or refrain from doing in
          connection with this Agreement except for its own gross
          negligence, willful misconduct or bad faith.  Anything in
          this Agreement to the contrary notwithstanding, in no
          event shall the Warrant Agent be liable for special,
          indirect or consequential loss or damage whatsoever
          (including, but not limited to, lost profits) even if the
          Warrant Agent has been advised of the likelihood of such
          loss or damage and regardless of the form of action.

                    15.8  Reliance on Documents.  The Warrant Agent
          will not incur any liability or responsibility to the
          Company or to any Holder for any action taken in reliance
          on any notice, resolution, waiver, consent, order,
          certificate, or other paper, document or instrument
          reasonably believed by it to be genuine and to have been
          signed, sent or presented by the proper party or parties.

                    15.9  Validity of Agreement.  The Warrant Agent
          shall not be under any responsibility in respect of the
          validity of this Agreement or the execution and delivery
          hereof (except the due execution hereof by the Warrant
          Agent) or in respect of the validity and execution of any
          Warrant (except its countersignature thereof); nor shall
          the Warrant Agent by any act hereunder be deemed to make
          any representation or warranty as to the authorization or
          reservation of any Warrant Shares (or other stock) to be
          issued pursuant to this Agreement or any Warrant, or as
          to whether any Warrant Shares (or other stock) will, when
          issued, be validly issued, fully paid and nonassessable,
          or as to the Exercise Price or the number or amount of
          Warrant Shares or other securities or other property
          issuable upon exercise of any Warrant.

                    15.10  Instructions from Company.  The Warrant
          Agent is hereby authorized and directed to accept
          instructions with respect to the performance of its
          duties hereunder from the Chairman, President and Chief
          Executive Officer or any Executive, Senior or other Vice
          President of the Company or any other employee of the
          Company expressly authorized in writing by any of such
          persons as having the authority to deliver instructions
          hereunder, and to apply to such officers or employees for
          advice or instructions in connection with its duties, and
          shall not be liable for any action taken or suffered to
          be taken by it in good faith in accordance with
          instructions of any such officers or employees.

                    SECTION 16.  Change of Warrant Agent.  The
          Warrant Agent may resign and be discharged from its
          duties under this Agreement by giving to the Company 30
          days' notice in writing.  The Warrant Agent may be
          removed by like notice to the Warrant Agent from the
          Company.  If the Warrant Agent shall resign or be removed
          or shall otherwise become incapable of acting, the
          Company shall appoint a successor to the Warrant Agent. 
          If the Company shall fail to make such appointment within
          a period of 30 days after such removal or after it has
          been notified in writing of such resignation or
          incapacity by the resigning or incapacitated Warrant
          Agent or by any Holder (who shall with such notice submit
          his Warrant for inspection by the Company), then any
          Holder may apply to any court of competent jurisdiction
          located in Boston, Massachusetts for the appointment of a
          successor to the Warrant Agent.  Pending appointment of a
          successor to the Warrant Agent, either by the Company or
          by such a court, the duties of the Warrant Agent shall be
          carried out by the Company.  Any successor Warrant Agent,
          whether appointed by the Company or such a court, shall
          be a bank or trust company, in good standing,
          incorporated under the laws of the United States of
          America or any state thereof and having at the time of
          its appointment as Warrant Agent a combined capital and
          surplus of at least $5,000,000.  After appointment, the
          successor Warrant Agent shall be vested with the same
          powers, rights, duties and responsibilities as if it had
          been originally named as Warrant Agent without further
          act or deed; but the former warrant agent shall deliver
          and transfer to the successor warrant agent any property
          at the time held by it hereunder, and execute and deliver
          any further assurance, conveyance, act or deed necessary
          for the purpose.  Failure to file any notice provided for
          in this Section 16, however, or any defect therein, shall
          not affect the legality or validity of the resignation or
          removal of the warrant agent or the appointment of the
          successor warrant agent, as the case may be.  In the
          event of such resignation or removal, the successor
          warrant agent shall mail, by first class mail, postage
          prepaid, to each Holder, written notice of such removal
          or resignation and the name and address of such successor
          warrant agent.

                    SECTION 17.  Identity of Transfer Agent. 
          Forthwith upon the appointment of any subsequent transfer
          agent for the Common Stock, or any other shares of the
          Company's capital stock issuable upon exercise of the
          Warrant, the Company will file with the Warrant Agent a
          statement setting forth the name and address of such
          subsequent transfer agent.

                    SECTION 18.  Notices.  Any notice pursuant to
          this Agreement by the Company or by any Holder to the
          Warrant Agent, or by the Warrant Agent or by any Holder
          to the Company, shall be in writing and shall be
          delivered in person, by overnight courier, or by
          facsimile transmission (with hard copy to follow promptly
          by first class mail or overnight courier), or mailed
          first class, postage prepaid (a) to the Company at its
          offices at 7 Continental Boulevard, Merrimack, New
          Hampshire, 03054, fax: (603) 429-8771, Attention: 
          General Counsel; or (b) to the Warrant Agent at 150
          Royall Street, Mail Stop 45-02-62, Canton, Massachusetts,
          02021, fax: (617) 575-2549, Attention:  Shareholder
          Services Division.  Each party hereto may from time to
          time change the address and facsimile numbers to which
          notices to it are to be delivered or mailed hereunder by
          notice to the other party.

                    Any notice required to be mailed pursuant to
          this Agreement by the Company or the Warrant Agent to the
          Holders shall be in writing and shall be mailed first
          class, postage prepaid, or otherwise delivered, to such
          Holders at their respective addresses on the books of the
          Warrant Agent.  Any other notices which the Company or
          the Warrant Agent may wish to provide to the Holder may
          be made in such manner (including by publication in a
          newspaper of national circulation) as the Company or the
          Warrant Agent, as the case may be, shall elect.  Any
          notice requested by any other person may be dispatched in
          the discretion of the Warrant Agent, but at no expense to
          the Warrant Agent or the Company.

                    SECTION 19.  Supplements and Amendments.  The
          Company and the Warrant Agent may from time to time
          supplement or amend this Agreement without the approval
          of any Holder in order to cure any ambiguity or to
          correct or supplement any provision contained herein
          which may be defective or inconsistent with any other
          provision herein, or to make any other provisions in
          regard to matters or questions arising hereunder which
          the Company and the Warrant Agent may deem necessary or
          desirable, which shall not adversely affect in any
          material manner the interest of the Holders.  The Company
          and the Warrant Agent may from time to time supplement or
          amend this Agreement in any other respect with the
          written consent of the Holders of not less than a
          majority of the Warrants then outstanding; provided,
          however, that no change in the number or nature of the
          securities purchasable upon the exercise of any Warrant,
          or increase in the Exercise Price of any Warrant, or
          acceleration of the Expiration Date of any Warrant, shall
          be made without the written consent of the Holder of such
          Warrant, other than such changes as are specifically
          prescribed by this Agreement as originally executed or
          are made in compliance with applicable law.

                    SECTION 20.  Successors.  All the covenants and
          provisions of this Agreement by or for the benefit of the
          Company or the Warrant Agent shall bind and inure to the
          benefit of their respective successors and assigns
          hereunder.

                    SECTION 21.  Applicable Law.  This Agreement
          and each Warrant issued hereunder shall be governed by
          and construed in accordance with the laws of The
          Commonwealth of Massachusetts applicable to contracts
          made and to be performed within such Commonwealth,
          without giving effect to principles of conflicts of laws. 
          The parties consent to the exclusive jurisdiction of the
          state and federal courts located in Boston,
          Massachusetts, in all cases arising out of this Agreement
          or the subject matter thereof, and to the service of
          process of such courts (and will not initiate or maintain
          an action in any other venue without the consent of both
          parties hereto).  Any action brought by any person (other
          than the Company and the Warrant Agent) arising under or
          relating to this Agreement and the Warrants shall be
          brought only in the state and federal courts located in
          Boston, Massachusetts.

                    SECTION 22.  Benefits of this Agreement. 
          Nothing in this Agreement shall be construed to give to
          any person or corporation other than the Company, the
          Warrant Agent, and the Holders any legal or equitable
          right, remedy or claim under this Agreement; this
          Agreement shall be for the sole and exclusive benefit of
          the Company, the Warrant Agent and the Holders of the
          Warrants.

                    SECTION 23.  Counterparts.  This Agreement may
          be executed in counterparts and by facsimile and each of
          such counterparts and facsimile copies shall for all
          purposes be deemed to be an original, and all such
          counterparts shall together constitute but one and the
          same instrument.

                    SECTION 24.  Severability.  Any term or
          provision of this Agreement which is invalid or
          unenforceable in any jurisdiction shall, as to that
          jurisdiction, be ineffective to the extent of such
          invalidity or unenforceability without rendering invalid
          or unenforceable the remaining terms and provisions of
          this Agreement or affecting the validity or
          enforceability of any of the terms or provisions of this
          Agreement in any other jurisdiction.  If any provision of
          this Agreement is so broad as to be unenforceable, the
          provision shall be interpreted to be only so broad as is
          enforceable.

                    SECTION 25.  Captions.  The captions of the
          Sections and subsections of this Agreement have been
          inserted for convenience only and shall have not
          substantive effect.


                    IN WITNESS WHEREOF, the parties hereto have
          caused this Agreement to be duly executed, all as of the
          day and year first above written.

          INCORPORATED UNDER THE LAWS OF THE STATE OF MARYLAND
          UNITRODE CORPORATION

          This certifies that FOR VALUE RECEIVED

          or registered assigns (the "Registered Holder") is the owner of
          the number of Common Stock Subscription Warrants (the "Warrants")
          specified above.  Each Warrant initially entitles the Registered
          Holder to purchase, subject to the terms and conditions set forth
          in this Warrant Certificate and the Warrant Agreement (as
          hereinafter defined), one fully paid and nonassessable share of
          Common Stock, par value $.20 per share (the "Common Stock"), of
          Unitrode Corporation, a Maryland corporation (the "Company"), at
          any time between August 21, 1996 and 5:00 p.m. (New York City
          time) on August 21, 1997 (the "Expiration Date"), upon surrender
          of this Warrant Certificate with the Subscription Form on the
          reverse hereof duly executed, at the office of The First National
          Bank of Boston designated for such purpose, as Warrant Agent, or
          its successor (the "Warrant Agent"), accompanied by payment of
          $28.467 per Warrant (the "Exercise Price") by certified or
          official bank check made payable to the Warrant Agent for the
          account of the Company.

                    This Warrant Certificate and each Warrant represented
          hereby are issued pursuant to and are subject in all respects to
          the terms and conditions set forth in the Warrant Agreement by
          and between the Company and the Warrant Agent (the "Warrant
          Agreement").  A copy of the Warrant Agreement may be obtained by
          the Registered Holder upon written request to the Company.

                    Upon the occurrence of certain events provided for in
          the Warrant Agreement, the Exercise Price and the number and kind
          of securities subject to purchase upon the exercise of each
          Warrant represented hereby are subject to adjustment.

                    Each Warrant represented hereby is exercisable at the
          option of the Registered Holder, but no fractional shares of
          Common Stock, or cash or other consideration in lieu thereof,
          will be issued.  In the case of the exercise of less than all of
          the Warrants represented hereby, the Company shall execute a new
          Warrant Certificate, which the Warrant Agent shall countersign
          and deliver, for the balance of such Warrants.

                    This Warrant Certificate is exchangeable, upon the
          surrender hereof by the Registered Holder at the office of the
          Warrant Agent designated for such purpose, for a new Warrant
          Certificate or Warrant Certificates entitling such Registered
          Holder to purchase a like aggregate number of shares of Common
          Stock as this Warrant Certificate entitles such Registered Holder
          to purchase.  A Registered Holder desiring to exchange this
          Warrant Certificate shall make such request in writing delivered
          to the Warrant Agent, and shall surrender, properly endorsed,
          this Warrant Certificate to be so exchanged.  Thereupon, the
          Warrant Agent shall countersign and deliver to the Registered
          Holder a new Warrant Certificate or Warrant Certificates as so
          requested, in the name of such Registered Holder, subject to the
          limitations provided in the Warrant Agreement.  No fractional
          Warrant Certificate shall be issued and no new Warrant
          Certificate entitling the Registered Holder thereof to purchase
          fractional shares will be issued.

                    Prior to the exercise of any Warrant represented
          hereby, the Registered Holder shall not be entitled to any rights
          of a stockholder of the Company, including, without limitation,
          the right to vote or to receive dividends, and shall not be
          entitled to receive any notice of any proceedings of the Company,
          except as provided in the Warrant Agreement.

                    The Company and the Warrant Agent may deem and treat
          the Registered Holder as the absolute owner hereof
          (notwithstanding any notation of ownership or other writing
          hereon made by anyone) for all purposes and shall not be affected
          by any notice to the contrary.

                    This Warrant Certificate is not valid unless
          countersigned by the Warrant Agent.

                    IN WITNESS WHEREOF, the Company has caused this Warrant
          Certificate to be duly executed, manually or in facsimile, by two
          of its officers thereunto duly authorized and a facsimile of its
          corporate seal to be imprinted thereon.
