 Item 4.   Description of Securities. 
  
      Not applicable. 
  
 Item 5.   Interests of Named Experts and Counsel. 
  
      None. 
  
 Item 6.   Indemnification of Officers and Directors. 
  
      The Maryland General Corporation Law, as amended from time to time
 (the "MGCL"), permits a Maryland corporation to include in its articles of
 incorporation a provision limiting the liability of its directors and
 officers to the corporation and its stockholders for money damages except
 for liability resulting from (a) actual receipt of an improper benefit or
 profit in money, property or services or (b) active and deliberate
 dishonesty established by a final judgment as being material to the cause
 of action.  The Registrant's Articles of Incorporation contain such a
 provision which eliminates such liability except (a) to the extent that it
 is proved that the person actually received an improper benefit or profit
 in money, property or services, for the amount of the benefit or profit in
 money, property or services actually received, or (b) to the extent that a
 judgment or other final adjudication adverse to the person is entered in a
 proceeding based on a finding in the proceeding that the person's action,
 or failure to act, was the result of active and deliberate dishonesty and
 was material to the cause adjudicated in the proceeding. 
  
 The Registrant's By-Laws obligate it, to the maximum extent permitted by
 Maryland law, to indemnify and to pay or reimburse reasonable expenses in
 advance of final disposition of a proceeding to (a) any present or former
 director or officer or (b) any individual who, while a director of the
 Registrant and at the request of the Registrant, serves or has served
 another corporation, partnership, joint venture, trust, employee benefit
 plan or any other enterprise as a director, officer, partner or trustee of
 such corporation, partnership, joint venture, trust, employee benefit plan
 or other enterprise.  The Registrant's By-Laws also permit the Registrant
 to indemnify and advance expenses to any person who served a predecessor of
 the Registrant in any of the capacities described above and to any employee
 or agent of the Registrant or a predecessor of the Registrant. 
  
 The MGCL requires a corporation (unless its articles of incorporation
 provide otherwise, which the Registrant's Articles of Incorporation do not)
 to indemnify a director or officer who has been successful, on the merits
 or otherwise, in the defense of any proceeding to which he is made a party
 by reason of his service in that capacity.  The MGCL permits a corporation
 to indemnify its present and former directors and officers, among others,
 against judgments, penalties, fines, settlements and reasonable expenses
 actually incurred by them in connection with any proceeding to which they
 may be made a party by reason of their service in those or other capacities
 unless it is established that (a) the act or omission of the director or
 officer was material to the matter giving rise to the proceeding and (i)
 was committed in bad faith or (ii) was the result of active and deliberate
 dishonesty, (b) the director or officer actually received an improper
 personal benefit in money, property or services or (c) in the case of any
 criminal proceeding, the director or officer had reasonable cause to
 believe that the act or omission was unlawful.  However, under the MGCL, a
 Maryland corporation may not indemnify for an adverse judgment in a suit by
 or in the right of the corporation but, pursuant to court order, may
 indemnify for expenses in such a suit.  In addition, the MGCL requires the
 Registrant, as a condition to advancing expenses, to obtain (a) a written
 affirmation by the director or officer of his good faith belief that he has
 met the standard of conduct necessary for indemnification by the Registrant
 required by the MGCL and as authorized by the Registrant's  By-Laws and (b)
 a written undertaking by or on his behalf to repay the amount paid or
 reimbursed by the Registrant if it shall ultimately be determined that the
 standard of conduct was not met. 
  
 The Registrant's officers and directors are insured against certain
 liabilities under a policy maintained by the Registrant with aggregate
 coverage of $10,000,000.

  5.1       Opinion of Ballard Spahr Andrews & Ingersoll, LLP regarding 
            legality of securities being registered.

  23.1      Consent of Ballard Spahr Andrews & Ingersoll, LLP (included as
            part of its opinion filed as Exhibit 5.1). 
 
  23.2      Consent of PricewaterhouseCoopers LLP.

  24.1      Power of Attorney (included on the signature page of this S-8
            Registration Statement). 

 Item 9.   Undertakings. 
       
 The undersigned Registrant hereby undertakes: 
  
   (1)    to file, during any period in which offers or sales are being
   made, a post-effective amendment to this registration statement: 
  
   (i)    to include any prospectus required by Section 10(a)(3) of the
   Securities Act of 1933, as amended;   
  
   (ii)   to reflect in the prospectus any facts or events arising after
   the effective date of the registration statement (or the most recent
   post-effective amendment thereof) which, individually or in the
   aggregate, represent a fundamental change  in the Information set forth
   in the registration statement.  Notwithstanding the foregoing, any 
   increase or decrease in the volume of securities offered (if the total
   dollar value of securities offered would not exceed that which was
   registered) and any deviation from the low or high end of the estimated
   maximum offering range may be reflected in the form of a prospectus
   filed with the Commission pursuant to Rule 424(b) if, in the aggregate,
   the changes in volume and price represent no more than a 20 percent
   change in the maximum aggregate offering price set forth in the
   "Calculation of Registration Fee" table in the effective registration
   statement; and  
  
   (iii)  To include any material Information with respect to the plan of
   distribution not previously disclosed in the registration statement or
   any material change to such Information in the registration statement. 
  
   (2)    That, for purposes of determining any liability under the
   Securities Act of 1933, each such post-effective amendment shall be
   deemed to be a new registration statement relating to the securities
   offered therein, and the offering of such securities at that time shall
   be deemed to be the initial bona fide offering thereof. 
  
   (3)    To remove from registration by means of a post-effective
   amendment any of the securities being registered which remain unsold at
   the termination of the offering. 
  
   (4)    The undersigned registrant hereby undertakes that, for purposes
   of determining any liability under the Securities Act of 1933, each
   filing of the registrant's annual report pursuant to Section 13(a) or
   15(d) of the Securities Exchange Act of 1934 (and, where applicable,
   each filing of an employee benefit plan's annual report pursuant to
   Section 15(d) of the Securities Exchange Act of 1934) that is
   incorporated by reference in the registration statement shall be deemed
   to be a new registration statement relating to the securities offered
   therein, and the offering of such securities at that time shall be
   deemed to be the initial bona fide offering thereof. 
  
   Insofar as indemnification for liabilities under the Securities Act of
   1933 may be permitted to directors, officers and controlling persons of
   the registrant pursuant to the provisions described above, or otherwise,
   the registrant has been advised that in the opinion of the Securities
   and Exchange Commission such indemnification is against public policy as
   expressed in the Securities Act and is therefore unenforceable. In the
   event that a claim for indemnification against such liabilities (other
   than the payment by the registrant of expenses incurred or paid by a
   director, officer or controlling person of the registrant in a
   successful defense of any action, suit or proceeding) is asserted by
   such director, officer, or controlling person in connection with the
   securities being registered, the registrant will, unless in the opinion
   of its counsel the matter has been settled by controlling precedent,
   submit to a court of appropriate jurisdiction the question whether such
   indemnification by it is against public policy as expressed in the
   Securities Act and will be governed by the final adjudication of such
   issue. 
  


                                 SIGNATURES
  
   Pursuant to the requirements of the Securities Act of 1933, the

 Hampshire, on this 30th day of November, 1998.

                           1989 STOCK OPTION PLAN
              (Amended and Restated as of September 18, 1996)
  
      1. Purposes of the Plan. The purposes of the Plan are to attract
 and retain the best available personnel for positions of substantial
 responsibility, to provide additional incentives to all the Employees and
 Consultants of the Company and to promote the success of the Company's
 business. It is intended that each option granted hereunder will either
 qualify as an "incentive stockoption", as defined in Section 422A(b) of the
 Code, or be a "non-statutory stock option." 
  
      2.   Definitions.  As used herein, the following definitions shall
 apply: 
                                -----------
  
      (a)  "Board" shall mean the Committee, if one has been appointed, or
 the Board of Directors of the Company, if no Committee has been appointed. 
  
      (b)  "Book Value" means the excess of the value of the assets of an
 entity over the liabilities of such entity (determined in accordance with
 United States generally accepted accounting principles, consistently
 applied). 
  
      (c)  "Change in Control" shall mean, (i) the occurrence of an event
 of a nature that would be required to be reported by the Company in
 response to Item 1 of a Current Report on Form 8-K (or any successor to
 such form) promulgated pursuant to the Exchange Act; provided, without
 limitation, such a Change inControl shall be deemed to have occurred if
 (A) any Person or Group (other than (I) the Company, (II) any wholly-owned
 Subsidiary of the Company, (III) any employee benefit plan, including,
 without limitation, an employee stock ownership plan, established by the
 Company or any wholly-owned Subsidiary of the Company or (IV) any trustee
 or other fiduciary holding securities under any employee benefit plan
 established by the Company or any wholly-owned Subsidiary of the Company),
 becomes the "beneficial owner" (as defined in Rule 13d-3 (or any successor
 to such rule) promulgated under the Exchange Act), directly or indirectly,
 of securities of the Company or any Material Subsidiary of the Company
 representing fifty percent (50%) or more of the combined voting power of
 the Company's or such Material Subsidiary's then outstanding securities or
 (b)during any period of twenty-four (24) months, individuals who at the
 beginning of such period constitute the Board cease for any reason to
 constitute at least a majority thereof, unless the election by the Board

      4.   Administration of the Plan. 
  
      (a)  Procedure.  The Plan shall be administered by the Board of
 Directors of the Company; provided, however, the Board of Directors may
 appoint a Committee consisting of not less than three members of the Board
 of Directors to administer the Plan on behalf of the Board of Directors,
 subject to such terms and conditions as the Board of Directors may
 prescribe. Once appointed, the Committee shall continue to serve until
 otherwise directed by the Board of Directors. From time to time the Board
 of Directors may increase the size of the Committee and appoint additional
 members thereof, remove members (with or without cause), and appoint new
 members in substitution therefor, fill vacancies however caused and remove
 all members of the Committee, and thereafter directly administer the Plan.
 Members of the Board who are either eligible for Options or have been
 granted Options may vote on any matters affecting the administration 
 of the Plan or the grant of any Options pursuant to the Plan, except that
 no such member shall act upon the granting of an Option to himself, but any
 such member may be counted in determining the existence of a quorum at any
 meeting of the Board during which action is taken with respect to the
 granting of Options to him. So long as the Company has equity securities
 registered pursuant to Section 12 of the Exchange Act, the Plan shall be
 administered in accordance with the requirements of Rule 16b-3 promulgated
 under the Exchange Act. 
  
      (b)  Powers of the Board. Subject to the provisions of the Plan, the
 Board shall have the authority, in its discretion: (i) to grant Options;
 (ii) to determine, in accordance with Section 8(b) of the Plan, the fair
 market value, per Share of the Common Stock; (iii) to determine, in
 accordance with Section 8(a) of the Plan, the exercise price per Share at
 which Options may be exercised; (iv) to determine the Employees and
 Consultants to whom, and the time or times at which, Options shall be
 granted, the number of Shares to be represented by each Option and whether
 such Options shall be Incentive Stock Options, Non-Statutory Stock Options
 or any combination thereof; (v) to interpret the Plan; (vi) to prescribe,
 amend and rescind rules and regulations relating to the Plan; (vii) to
 determine the terms and provisions of each Option granted (which need not
 be identical) and, with the consent of the holder thereof, to modify or
 amend any outstanding Option; (viii) to accelerate or defer (with the
 consent of the Optionee) the exercise date of any outstanding option; (ix)
 to authorize any person to execute on behalf of the Company any instrument
 required to effectuate the grant of an Option previously granted by the
 Board; and (x) to make all other determinations deemed necessary or
 advisable for the administration of the Plan.
  
      (c)  Effect of Board's Decision.  All decisions, determinations and
 interpretations of the Board shall be final and binding on all Optionees
 and any other holders of any Options granted under the Plan. 
  
      5.   Eligibility. 
  
      (a)  Grant of Options.  Incentive Stock Options may be granted only to
 Employees.  Non-Statutory Stock Options may be granted to either Employees
 or Consultants.  An Employee or Consultant who has been granted an Option
 may, if he is otherwise eligible, be granted an additional Option or
 Options. 
  
      (b)  No Right of Employment.  The Plan shall not confer upon any
 Optionee any right with respect to continuation of employment by, or
 consulting relationship with, the Company, nor shall it interfere in any
 way with his right or the Company's right to terminate his employment or
 consulting relationship at any time. 
  
      (c)  Limitation Upon Incentive Stock Options. Subject to the
 provisions of this Section 5, to the extent that the aggregate fair market
 value of Shares with respect to which Incentive Stock Options (determined
 without regard to the provisions of this Section 5) are exercisable for
 the first time by any Employee during any calendar year (under all plans
 of the Company or any Parent or Subsidiary of the Company) exceeds
 $100,000, such Options shall be treated as Options that are Non-Statutory
 Stock Options. For purposes of this Section 5(c), which shall be applied
 by taking Options into account in the order in which they were granted,
 the fair market value of any Shares shall be determined as of the time the
 Option with respect to such Shares is granted.
  
      6.   Term of Plan.  The Plan shall become effective upon the date of
 its adoption by the Board of Directors or, if earlier, the date of its
 approval by vote of the holders of a majority of the outstanding Shares
 entitled to vote on the adoption of the Plan.  It shall continue in effect
 for a term of ten (10) years from such date, unless sooner terminated under
 Section 12 of the Plan. 
  
      7.   Term of Option.  The term of each Option shall be ten (10) years
 from the date of grant thereof or such shorter term as may be determined by
 the Board.  However, in the case of any Incentive Stock Option granted to
 an Employee who, at the time of grant, owns stock representing more than
 ten percent (10%) of the voting power of all classes of stock of the
 Company or any Parent or Subsidiary of the Company, the term of such
 Incentive Stock Option shall be five (5) years from the date of grant
 thereof or such shorter time as may be determined by the Board. 
  
      8.   Exercise Price and Method of Payment. 
       
      (a)  Exercise Price.  The per Share exercise price for the Shares to
 be issued pursuant to exercise of an Option shall be such price as is
 determined by the Board, but in the case of an Incentive Stock Option, such
 price shall not be less than 100% (or, in the case of an Incentive Stock
 Option granted to an Employee who, at the time of grant, owns stock
 representing more than ten (10%) percent of the voting power of all classes
 of stock of the Company or any Parent or Subsidiary of the Company, 110%)
 of the fair market value per Share on the date such Option was granted. 
  
      (b)  Fair Market Value. For purposes of the Plan, the term "fair
 market value" on any date shall mean (i) if the Common Stock is listed or
 admitted to trade on a national securities exchange, the closing price of
 the Common Stock on the composite tape, as published in the Wall Street
 Journal, of the principal national securities exchange on which the Common
 Stock is so listed or admitted to trade, on such date or, if there is no
 trading in Shares on such date, thenthe closing price of the Common Stock
 as quoted on such composite tape on the next preceding date on which there
 was trading in such Shares; (ii) if the Common Stock is not listed or
 admitted to trade on a national securities exchange, then the closing
 price of the Common Stock as quoted on the National Market System of the
 National Association of Securities Dealers, Inc. ("NASD"); (iii) if the
 Common Stock is not listed or admitted to trade on a national securities
 exchange or the National Market System of the NASD, the mean between the
 bid and asked price for the Common Stock on such date, as furnished by the
 NASD through NASDAQ or a similar organization if NASDAQ is no longer
 reporting such information; or (iv) if the Common Stock is not listed or
 admitted to tradeon a national securities exchange or the National Market
 System of the NASD andif bid and asked prices for the Common Stock are not
 so furnished by the NASD or a similar organization, the values established
 by the Board for purposes of granting Options under the Plan. Fair market
 value shall be determined without regard to any restriction other than a
 restriction which, by its terms, will never lapse.
  
      (c)  Payment.  Payment for Shares issuable upon exercise of an Option
 shall be made in cash, or by check, promissory note, or if authorized by
 the Board, by delivery of other Shares having a fair market value on the
 date of delivery equal to the aggregate exercise price of the Shares as to
 which said Option is being exercised, or by any combination of such methods
 of payment or by any other method of payment as may be permitted under
 applicable law and as may be authorized by the Board. 
   
      9.   Exercise of Option. 
  
      (a)  Procedure for Exercise; Rights as a Stockholder. Any Option
 granted hereunder shall be exercisable at such times under such conditions
 as shall be determined by the Board, including performance criteria with
 respect to the Company and/or the Optionee, and as shall be permissible
 under the terms of the Plan. An Option may not be exercised for a fraction
 of a Share. An Option shall be deemed to be exercised when written notice
 of such exercise has been given to the Company in accordance with the
 terms of the Option by the person entitled to exercise the Option and full
 payment for the Shares with respect towhich the Option is exercised has
 been received by the Company. Full payment may, as authorized by the
 Board, consist of any form of consideration and method of payment
 allowable under Section 8(c) of the Plan. Until the issuance (as evidenced
 by the appropriate entry on the books of the Company or of a duly
 authorized transfer agent of the Company) of the stock certificate
 evidencing such Shares, no right to vote or receive dividends or any other
 rights as a, stockholder shall exist with respect to the Optioned Stock,
 notwithstanding the exercise of the Option. No adjustment will be made for
 a dividend or other right for which the record date is prior to the date
 as of which the stock certificate is issued, except as provided in Section
 11 of the Plan. Each exercise of an Option shall reduce, pro tanto, the
 total number of Shares that may thereafter be purchased under such Option.
 Subject to the provisions of Section 5(c), in no event shall the ex ercise
 of an Incentive Stock Option by an Employee have any effect on the
 exercise of any Non-Statutory Stock Options granted to such Employee, nor
 shall the exercise of a Non-Statutory Stock Option have any effect on the
 exercise of any Incentive Stock Options granted to such Employee.
  
      (b)  Termination of Status as an Employee. If an Optionee ceases to
 be an Employee, he may, but only prior to the earlier of (i) the close of
 business on the Expiration Date or (ii) the close of business on the last
 day of the period ending thirty (30) days after the date he ceases to be
 an Employee, exercise his Option to the extent that he was entitled to
 exercise it at the date of such termination. To the extent that he was not
 entitled to exercise the Option at such date, or does not exercise it
 within the time specified herein, the option shall terminate.
  
      (c)  Disability of Employee.  Notwithstanding the provisions of
 Section 9(b) above, in the event an Employee is unable to continue his
 employment with the Company as a result of his permanent and total
 disability (as defined in Section 22(e)(3) of the Code), he may, but only
 prior to the earlier of (i) the close of business on the Expiration Date or
 (ii) the close of business on the last day of the period ending twelve (12)
 months from the date of termination, exercise his Option to the extent he
 was entitled to exercise it at the date of such termination. To the extent
 that he was not entitled to exercise the Option at such date, or if he does
 not exercise it within the time specified herein, the Option shall
 terminate. 
  
      (d)  Death of Employee.  Notwithstanding the provisions of Section
 9(b)above, upon the death of an Employee, any Option held by him shall
 terminate and be of no further effect, except as provided below:   
  
           (i)  If the Employee's death occurs during the term of the Option
 and, at the time of his death, the Employee was an Employee of the Company
 and had been in Continuous Status as an Employee since the date of grant of
 the Option, the Option may be exercised, at any time prior to the earlier
 of (A) the close of business on the Expiration Date or (B) the close of
 business on the last day of the period ending twelve (12) months following
 the date of the Employee's death, by the Employee's estate or by the person
 who acquired the right to exercise the Option by bequest or inheritance, 
 but only as to the number of Shares subject to the Option as to  which the
 right to exercise had accrued to the Employee at the date of death. 
  
           (ii) If the Employee's death occurs within thirty (30) days after
 the termination of his Continuous Status as an Employee, the Option may be
 exercised, at any time prior to the earlier of (A) the close of business on
 the Expiration Date or (B) the close of business on the last day of the
 period ending three (3) months following the date of the Employee's death,
 by the Employee's estate or by a person who acquired the right to exercise
 the option by bequest or inheritance, but only to the extent of the right
 to exercise that had accrued at the date of termination. 
  
      (e)  Death, Disability or Termination of Consultants.  Options granted
 under the Plan to Consultants may contain such terms and conditions with
 respect to the death or disability of a Consultant or the termination of a
 Consultant's consulting relationship with the Company as the Board deems
 necessary or appropriate. Such terms and conditions will be set forth in
 the option agreement referenced in Section 15 of the Plan. 
  
      (f)  Vesting and Exercise of Vested Options. Each Option granted
 pursuant to the Plan may only be exercised to the extent that the Optionee
 is vested in such Option. Each Option shall vest separately in accordance
 with the option vesting schedule determined by the Board, which will be
 incorporated into the option agreement entered into between the Company
 and such Optionee. The option vesting schedule may be accelerated if, in
 the sole discretion of the Board, the acceleration of the option vesting
 schedule would be in the best interests the Company. Upon the occurrence
 of a Change in Control, all Options which have not previously been
 terminated, exercised or cancelled shall become fully vested and
 immediately exercisable.
  
      10.  Non-Transferability of Options.  No Option granted hereunder may
 be sold, pledged, assigned, hypothecated, transferred, or disposed of in
 any manner other than by will or by the laws of descent or distribution. 
 Any Option granted hereunder may be exercised, during the lifetime of the
 Optionee, only by the Optionee.  
  
      11.  Adjustments Upon Changes in Capitalization or Merger. 
  
      (a)  Reorganizations.  Subject to any required action by the
 stockholders of the Company, the number of Shares covered by each
 outstanding Option, and the aggregate number of Shares which have been
 authorized for issuance under the Plan, as well as the exercise price per
 Share covered by each such outstanding Option, shall be proportionately
 adjusted for any increase or decrease in the number of issued Shares
 resulting from a stock split or the payment of a stock dividend with
 respect to the Common Stock or any other increase or decrease in the number
 of issued Shares effected without receipt of consideration by the Company;
 provided, however, that conversion of any convertible securities of the
 Company shall not be deemed to have been "effected without receipt of
 consideration."  Such adjustment shall be made by the Board, whose
 determination in that respect shall be final, binding and conclusive. 
 Except as expressly provided herein, no issuance by the Company of shares
 of stock of any class, orsecurities convertible into shares of stock of any
 class, shall affect, and no adjustment by reason thereof shall be made with
 respect to, the number or price of Shares subject to an Option. 
  
      (b)  Dissolution/Liquidation.  In the event of the dissolution or
 liquidation of the Company, each Option shall terminate as of a date to be
 fixed by the Board; provided, however, that not less than thirty (30) days'
 written notice of the date so fixed shall be given to each Optionee. 
 During such period each Option which has not previously been terminated,
 exercised or cancelled will fully vest and become exercisable (subject to
 the expiration of the term of such Option), notwithstanding the vesting
 schedule set forth in the option agreement evidencing the grant of such
 Option or any performance based restrictions.  Upon the date fixed by the
 Board, any unexercised Option shall terminate and be of no further effect. 
  
      (c)  Corporate Transactions in which the Common Stock Remains
 Outstanding.  If a Corporate Transaction is consummated and immediately
 following the consummation of such Corporate Transaction the Persons who
 were holders of Shares immediately prior to the consummation of such
 Corporate Transaction do not receive any securities or other property
 ("Corporate Transaction Consideration") as a result of such Corporate
 Transaction and continue to hold solely the shares of Common Stock held by
 them immediately prior to the consummation of such Corporate Transaction,
 the Options will remain outstanding and will continue in full force and
 effect (without any modification) following the consummation of such
 Corporate Transaction. 
  
      (d)  Corporate Transactions in which the Common Stock Does Not Remain
 Outstanding.  If a Corporate Transaction is consummated and immediately
 following the consummation of such Corporate Transaction, the Persons who
 were holders of Shares immediately prior to the consummation of such
 Corporate Transaction do receive Corporate Transaction Consideration as a
 result of such Corporate Transaction or do not continue to hold solely the
 shares of Common Stock held by them immediately prior to the consummation
 of such Corporate Transaction, the terms and conditions of the Options will
 be modified as follows: 
  
           (i)  If the documentation pursuant to which a Corporate
 Transaction will be consummated provides for the assumption by the entity
 issuing Corporate Transaction Consideration to the Persons who were the
 holders of Shares immediately prior to the consummation of such Corporate
 Transaction of the Options granted pursuant to the Plan without any
 modification or amendment (other than Permitted Modifications), such
 Options will remain outstanding and will continue in full force and effect,
 subject to the Permitted Modifications, following the consummation of such
 Corporate Transaction. 
  
           (ii) If the documentation pursuant to which a Corporate
 Transaction will be consummated does not provide for the assumption by the
 entity issuing Corporate Transaction Consideration to the Persons who were
 the holders of Shares immediately prior to the consummation of such
 Corporate Transaction of the Options granted pursuant to the Plan without
 any modification or amendment (other than Permitted Modifications), all
 vesting restrictions (performance based or otherwise) will accelerate and
 the holders of such Options may (subject to the expiration of the term of
 such Options) exercise such Options without regard to such vesting
 restrictions during the ten (10) day period immediately preceding the
 consummation of such Corporate Transaction.  For purposes of the
 immediately preceding sentence, all performance based goals will be
 deemed to have been satisfied in full.  The Company will provide each 
 Optionee with reasonable notice of the termination of such vesting
 restrictions and the impending termination of such Options.  Upon the
 consummation of such a Corporate Transaction, all unexercised Options will
 automatically terminate and cease to be outstanding. 
  
      12.  Amendment and Termination of the Plan. 
           
      (a)  Amendment and Termination.  The Board may terminate the Plan at
 any time.  The Board may amend the Plan at any time in such respects as the
 Board  may deem advisable; provided, that the following amendments shall
 require approval of the holders of a majority of the outstanding shares of
 the Company entitled to vote: 
  
           (i) any change in the aggregate number of Shares which may be
 optioned and sold under the Plan, other than in connection with an
 adjustment under Section 11 of the Plan; 
  
           (ii) any change in the designation of the class of Employees
 eligible to be granted Incentive Stock Options; or  
  
           (iii) if the Company has a class of equity security registered
 under Section 12 of the Exchange Act at the time of such amendment, any
 change in the Plan which would materially increase the benefits accruing to
 participants under the Plan. 
  
      (b)  Effect of Amendment or Termination.  The amendment or termination
 of the Plan shall not change in any way the rights and obligations under
 any Option which was granted to an Optionee prior to such amendment or
 termination, unless the Optionee shall have consented to such change in
 writing. 
  
      13.  Conditions Upon Issuance of Shares. No Options granted hereunder
 may be exercised and no Shares issuable upon exercise of such Options may
 be transferred unless and until the Board determines that such
 exercise/transfer will be made in compliance with all applicable laws,
 rules and regulations, including, without limitation, applicable
 securities laws, rules and regulations and the rules and regulations of
 any securities exchange or automated transaction reporting system on which
 the securities of the Company are listed or admitted to trading. The
 Company does not have any obligation to take any action to register or
 qualify Shares pursuant to applicable securities laws or to perfect an
 exemption from such registration/qualification requirements. As a
 condition to the exercise of an Option, the Company may require the person
 exercising such Option to represent and warrant at the time of any such
 exercise that the Shares are being purchased only for investment and
 without any present intention to sell or distribute such Shares if, in the
 opinion of counsel for the Company, such a representation is required by
 any of the aforementioned relevant provisions of law.
  
      14.  Reservation of Shares.  The Company, during the term of the Plan
 and each Option, will at all times reserve and keep available such number
 of Shares as shall be sufficient to satisfy the requirements of the Plan
 and such Options.  The inability of the Company to obtain authority from
 any regulatory body having jurisdiction, which authority is deemed by the
 Company's counsel to be necessary to the lawful issuance and sale of any
 Shares hereunder, shall relieve the Company of any liability in respect of
 the failure to issue or sell such Shares as to which such requisite
 authority shall not have been obtained. 
  
      15.  Option Agreement.  Options shall be evidenced by written option
 agreements in such form as the Board shall approve, and shall contain, in
 the case of Incentive Stock Options, such provisions as shall be necessary
 for the Options to which such option agreements relate to qualify as to
 Incentive Stock Options. 
  
      16.  Stockholder Approval. If the Plan is adopted by action of the
 Board of Directors prior to approval by the Company's stockholders,
 continuance of the Plan shall be subject to approval of the Plan by the
 stockholders of the Company within 12 months after the date on which the
 Plan is so adopted. With respect to any amendment of the Plan requiring
 approval of the Company's stockholders, such approval shall be obtained
 within 12 months before or after the date such amendment is adopted;
 provided, that if the Company has a class of equity security registered
 under Section 12 of the Exchange Act at the time of such amendment, such
 amendment shall not become effective until such approval has been
 obtained. If, after the Plan has been adopted, the Company registers any
 class of any equity security pursuant to Section 12 of the Exchange Act,
 the Plan and all amendments thereto since the Plan's adoption shall be
 submitted to the stockholders of the Company for their approval. Such
 approval shall be obtained at or prior to the first annual meeting of
 stockholders held subsequent to the first such registration of securities.
 Such approval of the stockholders, and their approval of any subsequent
 amendment to the Plan requiring their approval, shall be solicited: (i)
 substantially in accordance with Section 14(a) of the Exchange Act and the
 rules and regulations promulgated thereunder; or (ii) after the Company
 has furnished in writing to the stockholders entitled to vote
 substantially the same information concerning the Plan as that which would
 be required by the rules and regulations then in effect under Section
 14(a).

                         Purpose of Plan; Administration 
                         ------------------------------- 
  
   1.1  Purpose.  The purpose of the BENCHMARQ Microelectronics, Inc. 1995
 Flexible Stock Option Plan (the "Plan") is to strengthen BENCHMARQ
 Microelectronics, Inc. (the "Company") by providing a means of retaining
 and attracting competent personnel by extending to participating officers,
 employees, directors and consultants (as defined in Section 1.3) of the
 Company, or of a Parent or Subsidiary (as defined herein) of the Company,
 added long-term incentives for high levels of performance and for unusual
 efforts designed to improve the financial performance of the Company.  It is
 intended that this purpose be achieved through the opportunity for ownership
 of shares of the common stock, par value $.001 per share, of the Company
 (the "Stock") and the benefits of stock appreciation offered under the Plan. 
 It is further intended that pursuant to this Plan the Committee (as defined
 in Section 1.2) may grant either incentive stock options as defined in
 Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"),
 or nonqualified stock options.  As used herein, the term "Parent" will be
 deemed to have the meaning set forth in Section 424(e) of the Code and the
 term "Subsidiary" will be deemed to have the meaning set forth in Section
 424(f) of the Code. 
  
   1.2  Administration.  The Plan shall be administered by the Compensation
 Committee (the "Committee") established by the Board of Directors of the
 Company (the "Board").  Such Committee shall be comprised of two (2) or more
 directors, each of whom shall be "non-employee directors," as defined in
 Rule 16b-3, promulgated under the Securities Exchange Act of 1934, as
 amended (the "Exchange Act").  Subject to the express provisions of the
 Plan, the Committee shall have the authority to construe and interpret the
 Plan, to define the terms used in the Plan, to prescribe, amend and rescind
 rules and regulations relating to the administration of the Plan, to
 determine the duration and purposes of leaves of absence which may be
 granted to participants without constituting a termination of their
 employment or other service for purposes of the Plan to amend or modify any
 outstanding option (with the consent of the Optionee (as defined
 herein)), to accelerate or defer the exercise date of any outstanding option
 (with the consent of the Optionee), and to make all other determinations
 necessary or advisable for the administration of the Plan.  The
 determinations of the Committee on all matters referred to in this Plan
 shall be conclusive.  No member of the Committee shall be liable for any
 action, failure to act, determination or interpretation made in good faith
 with respect to the Plan or any transaction under the Plan.  Subject to the
 express provisions of the Plan, the Committee shall determinefrom the
 eligible class those individuals to whom incentive stock options
 or nonqualified stock options under the Plan shall be granted (the
 "Optionees"), the terms and provisions (which need not be identical) of the
 respective agreements (the "Option Agreements") evidencing such options, the
 time at which options shall be granted, and the number of shares of Stock
 subject to each option. 
  
   1.3  Participation.  Officers, employees, directors and consultants of
 the Company or any Parent or Subsidiary of the Company shall be eligible
 for selection to participate in the Plan upon approval by the Committee;
 provided, however, that only those individuals who are employed by the
 Company or a Parent or Subsidiary of the Company shall be eligible to
 receive incentive stock options.  For purposes of the Plan, the term
 "consultant" shall mean any person or entity who or which is engaged by the
 Company or a Parent or Subsidiary of the Company to render consulting
 services and is compensated for such consulting services. 
  
   1.4  Stock Subject to the Plan.  Subject to adjustment as provided in
 Section 3.1 hereof, the shares to be offered under the Plan shall be
 treasury shares or shares of the Company's authorized but unissued Stock. 
 The aggregate number ofshares of Stock to be issued upon exercise of all
 options granted under the Plan shall not exceed 1,247,576 shares (after
 giving effect to all exercises of options prior to March 11, 1997), subject
 to adjustment as set forth in Sections 3.1 hereof.  The aggregate number of
 shares of Stock to be issued to any individual within any calendar year
 shall not exceed 100,000 shares.  If any option granted hereunder shall
 lapse or terminate for any reason without having been fully exercised, the
 shares subject thereto shall again be available for purposes of the Plan. 
  
   1.5  Restrictions on Exercise.  No options granted hereunder may be
 exercised and no shares of Stock issuable upon exercise of such options may
 be transferred unless and until the Committee determines that such
 exercise/transfer will bemade in compliance with all applicable laws, rules
 and regulations, including, without limitation, applicable securities laws,
 rules and regulations and the rules and regulations of any securities
 exchange or automated transaction reporting system on which the securities
 of the Company are listed or admitted to trading.  The Company does not have
 any obligation to take any action to register or qualify shares of Stock
 pursuant to applicable securities laws or to perfect an exemption from such
 registration/qualification requirements.  As acondition to the exercise of
 an option, the Company may require the person exercising such option to
 represent and warrant at the time of any such exercise that the shares of
 Stock are being purchased only for investment and without any present
 intention to sell or distribute such shares of Stock if, in the opinion of
 counsel for the Company, such a representation is required by any of
 theafore mentioned relevant provisions of law.    
  
  
                                       II
                                  Stock Options
  
 2.1  Grant and Option Price.   The Committee may grant one or more options
 to any eligible individual.  Options granted under the Plan shall be
 granted within ten (10) years from the earlier of the date the Plan is
 adopted by the Board or approved by the stockholders of the Company, and
 such options may be intended toqualify as Incentive Stock Options (as
 hereinafter defined), or the Committee may in its discretion grant
 nonqualified stock options under the Plan.  All options shall be subject to
 the terms and conditions set forth in the Plan and such other terms and
 conditions established by the Committee as are not inconsistent with the
 purposes and provisions of the Plan.  Except as otherwise provided herein,
 the purchase price of the Stock covered by each option shall be determined
 by the Committee and set forth in the Option Agreement, but as to Stock
 covered by an Incentive Stock Option the purchase price shall not be less
 than 100% of the Fair Market Value (as such term is defined in this Section
 2.1) of such Stock on the date of the grant of the option.  Notwithstanding
 the foregoing, the purchase price of Stock covered by an Incentive Stock
 Option granted to any individual who owns or is deemed to own more than 10%
 of the total combined voting power and value of all classes of stock of the
 Company, its Parent, if any, or a Subsidiary, shall not be less than 110% of
 the Fair Market Value (as such term is defined in this Section 2.1) of such
 Stock on the date of the grant of the option.  For purposes of the Plan, the
 term "Fair Market Value" on any date shall mean (i) if the Stock is
 listed or admitted to trade on a national securities exchange, the closing
 price of the Stock on the Composite Tape, as published in the Wall Street
 Journal, of the principal national securities exchange on which the Stock is
 so listed or admitted to trade, on such date or, if there is no trading of
 the Stock on such date, then the closing price of the Stock as quoted on
 such Composite Tape on the next preceding date on which there was trading
 in such shares; (ii) if the Stock is not listed or admitted to trade or a
 national securities exchange, then the closing price of the Stock as quoted
 on the National Market System of the National Association of Securities
 Dealers, Inc. ("NASD"); (iii) if the Stock is not listed or admitted to
 trade on a national securities exchange or the National Market System of the
 NASD, the mean between the bid and asked price for the Stock on such date,
 as furnished by the NASD through NASDAQ or a similar organization if NASDAQ
 is no longer reporting such information; or (iv) if the Stock is not listed
 or admitted to trade on a national securities exchange or the National
 Market System of the NASD and if bid and asked prices for the Stock are not
 so furnished by the NASD or a similar organization, the values established
 by the Committee for purposes of granting options under the Plan.  In
 addition to the above rules, Fair Market Value shall be determined
 without regard to any restriction other than a restriction which, by its
 terms, will never lapse. 
  
   2.2  Stock Option Agreement.  Subject to the provisions of Section 1.2
 hereof, each option granted pursuant to the Plan shall be evidenced by a
 Stock Option Agreement in substantially the form of Exhibit "A" or "B"
 attached hereto and incorporated fully herein by reference (each, an "Option
 Agreement").  Exhibit "A" shall be used whenever such option is intended to
 be an "incentive stock option" within the meaning of Section 422 of the Code
 ("Incentive Stock Option").  Exhibit "B" shall be used whenever such option
 is intended to be a nonqualified stock option, as determined in the sole and
 absolute discretion ofthe Committee. 
  
   2.3  Option Period.  Except as otherwise provided herein, each option and
 all rights or obligations thereunder shall expire on such date as the
 Committee shall determine (the "Expiration Date"), but not later than the
 tenth anniversary of the date on which the option is granted, and shall be
 subject to earlier termination as hereinafter provided.  Notwithstanding the
 foregoing, the Expiration Date of an Incentive Stock Option granted to any
 individual who owns or is deemed to own more than 10% of the total combined
 voting power and value of all classes of stock of the Company, its Parent,
 if any, or a Subsidiary, shall be a date which is not later than the fifth
 anniversary of the date on which the option is granted, and shall be subject
 to earlier termination as hereinafter provided. 
  
   2.4  Terms of Options.  Each option granted under this Plan by
 its terms shall require the officer, employee, director or consultant
 granted such option to remain in the continuous employ or service of the
 Company or of a Parent or Subsidiary of the Company for such period of time,
 if any, from the date of grant of such option before the right to exercise
 any part of the option will accrue as the Committee may determine at the
 time of granting such option. 
  
   2.5  Exercise of Options.  Each option shall become exercisable
 and the total number of shares of Stock subject thereto shall be as the
 Committee shall determine, as set forth in the Option Agreement evidencing
 such option.  The purchase price of the Stock purchased upon exercise of an
 option shall be paid in full in cash or by check at the time of each
 exercise of an option or by such other consideration as may be provided for
 in the Option Agreement by the Committee; provided, however, that if the
 Option Agreement so provides and upon receipt of all regulatory approvals,
 the person exercising the option may deliver, in payment of a portion or all
 of the purchase price, shares of Stock, including a multiple series of
 exchanges of such Stock, which shall be valued at the Fair Market Value of
 such Stock on the date of exercise of the option.  No options shall be
 exercisable except in respect of whole shares of Stock. 
  
   2.6  Nontransferability of Options.  An option granted under the Plan
 shall, by its terms, be nontransferable by the Optionee other than by will
 or by the laws of descent and distribution, and shall be exercisable during
 the Optionee's lifetime only by the Optionee or by the Optionee's duly
 appointed guardian or personal representative.       

   2.7  Termination of Relationship. 
  
        (a) If the employment or other service of the Optionee is terminated
 for  any reason other than (i) Disability (as hereinafter defined) of the
 Optionee, or (ii) death of the Optionee, an option (to the extent
 otherwise exercisable on the date of such termination) shall be
 exercisable by the Optionee at any time prior to the Expiration Date of
 the option or within thirty (30) days after the date of such termination
 of employment or other service, whichever is the shorter period. 
  
        (b) If the Optionee's employment or other service is terminated by
 reason  of the Optionee's Disability, an option (to the extent otherwise
 exercisable on the date of the Optionee's termination of employment or
 other service by reason of Disability) shall be exercisable by the
 Optionee at any time prior to the Expiration Date of the option or within
 twelve (12) months after the date of such termination, whichever is the
 shorter period.  As used herein, the term "Disability" shall mean the
 inability to engage in any substantial gainful activity by reason of any
 medically determinable physical or mental impairment which can be expected
 to result in death or which has lasted or can be expected to last for a
 continuous period of not less than twelve (12) months.  The determination
 of whether or not an Optionee's employment or service is terminated by
 reason of Disability shall be in the sole and absolute discretion of the
 Committee.  An individual shall not be considered Disabled unless he
 furnishes proof of the existence thereof in such form and  manner, and at
 such times, as the Committee may require. 
  
        (c) If an Optionee dies while in the employ or other service of the 
 Company or of a Parent of Subsidiary of the Company, the option shall be 
 exercisable (to the extent otherwise exercisable on the date of the death
 of  such Optionee) by the person or persons entitled to do so under the
 Optionee's  will, or, if the Optionee shall fail to make testamentary
 disposition of said option or shall die intestate, by the Optionee's legal
 representative or representatives, at any time prior to the Expiration
 Date of the option or within twelve (12) months after the date of such
 death, whichever is the shorter period. 
  
        (d) If an Optionee dies within thirty (30) days after his
 termination of employment or other service, or within the twelve-month
 period described in subsection (b) above, an option shall be exercisable
 (to the extent otherwise exercisable on the date of such termination) by
 the person or persons entitled to do so under the Optionee's will, or, if
 the Optionee shall fail to make testamentary disposition of said option or
 shall die intestate, by the Optionee's legal representative or
 representatives, at any time prior to the Expiration Date of the option or
 within three (3) months after the date of death, whichever is the shorter
 period. 
  
   2.8  Issuance of Stock Certificates.  Upon exercise of an option, but
 subject to the provisions of Section 3.6 of this Plan, the person
 exercising the option shall be entitled to one (1) stock certificate
 evidencing the shares of Stock acquired upon such exercise; provided,
 however, that any person who tenders shares of Stock in payment of a portion
 or all of the purchase price of Stock purchased upon exercise of the option
 shall be entitled to receive a separate certificate representing the number
 of shares purchased in consideration of the tender of such Stock. 
  
   2.9  Limitation on Grant of Incentive Stock Options.  The aggregate Fair
 Market Value (determined at the time the option is granted) of the Stock
 with respect to which Incentive Stock Options are exercisable for the first
 time byan Optionee during any calendar year (under all such plans of the
 individual's employer and its Parent or Subsidiary) shall not exceed
 $100,000.  In the event the limits of this Section 2.9 would otherwise be
 exceeded, the Optionee may still exercise his option, but such option, to
 the extent of such excess, shallbe deemed to be a nonqualified stock
 option.  
             
   2.10 Other Limitations.  The Board shall impose any other limitations on
 the terms and conditions of Incentive Stock Options granted under the Plan
 required in order that such options qualify as Incentive Stock Options as
 that term is defined in Section 422 of the Code. 
  
   2.11 "Stand-Off" Agreement.  By exercising an option granted under the
 Plan, each Optionee will be deemed to have agreed for a period of time (not
 to exceed 90 days, but up to 270 days if approved by a majority of the
 Board) from the effective date of any registration (other than a
 registration effected solely to implement an employee benefit plan or a
 transaction to which Rule 145 promulgated under the Securities Act of 1933,
 as amended (the "Act"), is applicable) of securities of the Company (upon
 request of the Company or of the underwriters managing any underwritten
 offering of the Company's securities) not to sell, make any short sale of,
 loan, grant any option for the purchase of, or otherwise dispose of any
 shares of Stock received upon exercise of an option orany shares of Stock
 covered by an option granted under the Plan, other than shares of Stock
 included in the registration, without the prior written consent of the
 Company or such underwriters, as the case may be. 
  
   2.12 Vesting and Exercise of Vested Options.  Each option granted
 pursuant to the Plan may only be exercised to the extent that the Optionee
 is vested in such option.  Each option shall vest separately in accordance
 with the option vesting schedule determined by the Committee, which will be
 incorporated into the Option Agreement entered into between the Company and
 such Optionee.  The option vesting schedule may be accelerated if, in the
 sole discretion of the Committee, the acceleration of the option vesting
 schedule would be in the best interests of the Company. 
  
  
                                      III
                                Oher Provisions
    
   3.1  Adjustments Upon Changes in Capitalization or Merger.  Subject to
 any required action by the stockholders of the Company, the number of
 shares of Stock covered by each outstanding option, and the aggregate number
 of shares of Stock which have been authorized for issuance under the Plan,
 as well as the exercise price per share of Stock covered by each such
 outstanding option, shall be proportionately adjusted for any increase or
 decrease in the number of issued shares of Stock resulting from a stock
 split or the payment of a stock dividend with respect to the  Stock or any
 other increase or decrease in the number of issued shares of Stock effected
 without receipt of consideration by the Company; provided, however, that
 conversion of any convertible securities of the Company shall not be deemed
 to have been "effected without receipt of consideration".  Such adjustment
 shall be made by the Board, whose determination in that respect shall be
 final, binding and conclusive.  Except as expressly provided herein,
 noissuance by the Company of shares of stock of any class, or
 securities convertible into shares of stock of any class, shall affect, and
 no adjustment by reason thereof shall be made with respect to, the number or
 price of shares of Stock subject to an option. 
  
   In the event of the dissolution or liquidation of the Company, each
 Option shall terminate as of a date to be fixed by the Committee; provided,
 however, that not less than thirty (30) days' written notice of the date so
 fixed shall be given to each Optionee.  During such period each option which
 has not previously been terminated, exercised or cancelled will fully vest
 and become exercisable (subject to the expiration of the term of such
 option), notwithstanding the vesting schedule set forth in the Option
 Agreement evidencing the grant of such option or any performance based
 restriction.  Upon the date fixed by the Committee, any unexercised option
 shall terminate and be of no further effect. 
  
   If a Corporate Transaction (as hereinafter defined) is consummated
 and immediately following the consummation of such Corporate Transaction the
 persons who were holders of shares of Stock immediately prior to the
 consummation of such Corporate Transaction do not receive any securities or
 other property ("Corporate Transaction Consideration") as a result of
 such Corporate Transaction and continue to hold solely the shares of Stock
 held by them immediately prior to the consummation of such Corporate
 Transaction, the options will remain outstanding and will continue in full
 force and effect (without any modification) following the consummation of
 such Corporate Transaction. 
  
   If a Corporate Transaction is consummated and immediately following
 the consummation of such Corporate Transaction the persons who were holders
 of shares of Stock immediately prior to the consummation of such
 Corporate Transaction do receive Corporate Transaction Consideration as a
 result of such Corporate Transaction or do not continue to hold solely the
 shares of Stock held by them immediately prior to the consummation of such
 Corporate Transaction, the terms and conditions of the options will be
 modified as follows: 
  
      (i) If the documentation pursuant to which a Corporate Transaction
 will be  consummated provides for the assumption by the entity issuing
 Corporate Transaction Consideration to the persons who were the holders of
 shares of Stock immediately prior to the consummation of such Corporate
 Transaction of the options granted pursuant to the Plan without any
 modification or amendment (other than Permitted Modifications (as
 hereinafter defined)), such options will remain outstanding and will
 continue in full force and effect, subject to the Permitted Modifications,
 following the consummation of such Corporate Transaction. 
  
      (ii) If the documentation pursuant to which a Corporate Transaction
 will be consummated does not provide for the assumption by the entity
 issuing Corporate Transaction Consideration to the persons who were the
 holders of shares of Stock immediately prior to the consummation of such
 Corporate Transaction of the options granted pursuant to the Plan without
 any modification or amendment (other than Permitted Modifications), all
 vesting restrictions (performance based or otherwise) will accelerate and
 the holders of such options may (subject to the expiration of the term of
 such options) exercise such options without regard to such vesting
 restrictions during the ten (10) day period immediately preceding the
 consummation of such Corporate Transaction.  For purposes of the
 immediately preceding sentence, all performance based goals will be deemed
 to have been satisfied in full.  The Company will provide each Optionee
 with reasonable notice of the termination of such vesting restrictions and
 the impending termination of such options.  Upon the consummation of such a
 Corporate Transaction, all unexercised options  will automatically
 terminate and cease to be outstanding.  As used herein, the term "Corporate
 Transaction" will be deemed to mean any sale of all or substantially all of
 the assets of the Company or the merger of the Company with or into another
 corporation.  As used herein, the term "Permitted Modifications" will be
 deemed to mean any modification of an option which is made in connection
 with a Corporate Transaction and which provides that subsequent to the
 consummation of the Corporate Transaction (i) the  exercise price of such
 option will be proportionately adjusted to reflect the exchange ratio
 applicable to the particular Corporate Transaction and/or (ii) the
 nature and amount of consideration to be received upon exercise of the
 option will be the same (on a per share basis) as was received by persons
 who were holders ofshares of Stock immediately prior to the consummation of
 the Corporate Transaction. 
  
   Notwithstanding the foregoing, in the event of the consummation of a
 Corporate Transaction in which a Change in Control (as hereinafter defined)
 occurs, all vesting restrictions (performance based or otherwise)
 applicable to options will accelerate and the holders of such options may
 (subject to the expiration of the term of such options) exercise such
 options without regard to such vesting restrictions.  For purposes of the
 immediately preceding sentence, all performance based goals will be deemed
 to have been satisfied in full.  As used herein, the term "Change in
 Control" will be deemed to mean (i) a merger of the Company with or into
 another corporation is consummated, other than a merger that would result in
 the holders of voting securities of the Company outstanding immediately
 prior thereto owning (directly or indirectly) not less than fifty percent
 (50%) of the combined voting power of the voting securities of the surviving
 or resulting entity outstanding immediately after such merger or (ii) an
 agreement for the sale or other disposition of all or substantially all of
 the Company's assets (evaluated on a consolidated basis, without regard to
 whether the sale or disposition is effected via a sale or disposition
 of assets of the Company, the sale or disposition of the securities of one
 or more Subsidiaries of the Company or the sale or disposition of the assets
 of one or more Subsidiaries of the Company) is consummated. 
  
   3.2  Continuation of Employment.  Nothing contained in the Plan (or in
 any option granted pursuant to the Plan) shall confer upon any Optionee any
 right to continue in the employ or other service of the Company or any
 Parent or Subsidiary or constitute any contract or agreement of employment
 or interfere in any way with the right of the Company or any Parent or
 Subsidiary to reduce any person's compensation from the rate in existence at
 the time of the granting of an option or to terminate such person's
 employment or other service.  Nothing contained herein or in any Option
 Agreement shall affect any other contractual rights of an employee. 
  
   3.3  Withholding.  The Company or the Parent or any Subsidiary of the
 Company shall have the right to deduct any sums that the Committee
 reasonably determines that federal, state or local tax law requires to be
 withheld with respect to the exercise of any option or as otherwise may be
 required by those laws.  The Company or the Parent or any Subsidiary of the
 Company may require as a condition to issuing shares of Stock upon exercise
 of an option that the Optionee or other person exercising the option pay any
 sums that federal, state or local tax law requires to be withheld with
 respect to the exercise.  Neither the Company nor the Parent or any
 Subsidiary of the Company shall be obligated to advise any Optionee of the
 existence of the tax or the amount which the employer corporation will be so
 required to withhold.  Upon the exercise of a nonqualified stock option, if
 tax withholding is required, an Optionee may, with the consent of the
 Committee, have shares of Stock withheld ("Share Withholding") by the
 Company from the shares of Stock otherwise to be received; provided, that if
 the Optionee is subject to the provisions of Section 16 under the Exchange
 Act, no Share Withholding shall be permitted unless such transaction
 complies with the requirements of Rule 16b-3 promulgated under the Exchange
 Act.  The number of shares so withheld should have an aggregate Fair Market
 Value on the date of exercise sufficient to satisfy the applicable withholding
 taxes. 
  
   3.4  Amendment and Termination.  The Board may at any time suspend or
 terminate the Plan and may, with the consent of the holder of an option,
 make such modifications of the terms and conditions of such holder's option
 as it shall deem advisable.  No option may be granted during any suspension
 of the Plan or after such termination.  The amendment, suspension or
 termination of the Plan shall not, without the consent of the Optionee,
 alter or impair any rights or obligations under any option theretofore
 granted under the Plan.  The Board may at any time amend the Plan as it
 shall deem advisable without further action on the part of the stockholders
 of the Company; provided, that the Board may not amend any provision of the
 Plan relating to the amount and price of Stock subject to the option granted
 hereunder or the timing of grants hereunder more than once every six (6)
 months, other than to comport with changes in the Code, the Employee
 Retirement Income Security Act, or the rules thereunder; and provided
 further, that any amendment to the Plan must be approved by the
 stockholders of the Company, if the amendment would (i) increasethe
 aggregate number of shares of Stock which may be issued pursuant to
 options granted under the Plan; (ii) change the minimum option price; (iii)
 increase the maximum terms of options provided for herein; (iv) materially
 modify the requirements as to eligibility for participation in the Plan; (v)
 remove the administration of the Plan from the Committee; or (vi)
 materially increase the benefits accruing to holders of options under the
 Plan.  Notwithstanding the above, the Committee may grant to an Optionee,
 if he is otherwise eligible, additional options or, with the consent of the
 Optionee, may grant a new option in lieu of an outstanding option, at a
 price and for a term which in any respect is greater or less than that of
 the earlier option, subject to the general limitations of Article II hereof. 
  
   3.5  Time of Grant and Exercise.  The granting of an option pursuant to
 the Plan shall take place at the time of the Committee's action, as
 described in Section 2.1 hereof; provided, however, that if the appropriate
 resolutions of the Committee indicate that an option is to be granted as of
 and at some future date, the date of grant shall be such future date.  In
 the event action by the Committee is taken by written consent of its
 members, the action by the Committee shall be deemed to have been taken at
 the time the last member required for a valid action of the Committee signs
 the consent.  An option shall be deemed to be exercised when the Secretary
 of the Company receives written notice of such exercise from the person
 entitled to exercise the option together with payment of the purchase price
 made in accordance with Section 2.5 of this Plan. 
  
   3.6  Privileges of Stock Ownership; Non-Distributive Intent.  The holder
 of an option shall not be entitled to the privileges of ownership as to any
 shares of Stock not actually issued and delivered to the holder.  Upon
 exercise of an option for Stock at a time when there is not in effect under
 the Act a registration statement relating to the shares of Stock issuable
 upon exercise thereof or not available for delivery a prospectus, the holder
 of the option shall represent and warrant in writing to the Company that,
 inter alia, the shares of Stock purchased are being acquired for investment
 and not with a view to the resale or distribution thereof.  No shares of
 Stock shall be issued upon the exercise of any option unless and until there
 shall have been compliance with any then applicable requirements of the
 Securities and Exchange Commission (the "Commission"), other regulatory
 agencies having jurisdiction and any exchanges or automated quotation
 systems upon which securities subject to the option may be listed or
 admitted to trading. 
  
   3.7  Effective Date of the Plan.  The Plan shall be effective upon
 approval by the affirmative vote of the holders of a majority of the
 outstanding shares of Stock present and entitled to vote at a meeting duly
 held or by the written consent of the holders of a majority of the shares of
 Stock entitled to vote. 
  
   3.8  Expiration.  Unless previously terminated by the Board, the Plan
 shall expire at the close of business on the date which is the last day of
 the ten (10) year period beginning on the date on which the stockholders
 approve the Plan, and no option shall be granted under it thereafter, but
 such expiration shall not affect any option theretofore granted. 
  
   3.9  Governing Law.  The Plan and the options issued hereunder shall be
 governed by, and construed and enforced in accordance with, the laws of
 the State of Delaware applicable to contracts made and performed within that
 State.  

   3.10  No Liability for Good Faith Determinations.  Neither the
 members of the Board nor any member of the Committee shall be liable for
 any act, omission or determination taken or made in good faith with respect
 to the Plan or any option granted under it. 
  
   3.11 Execution of Receipts and Releases.  Any payment or any issuance or
 transfer of shares of Stock to the Optionee, or to his legal
 representative, heir, legatee or distributee, in accordance with the
 provisions hereof, shall, to the extent thereof, be in full satisfaction of
 all claims of such persons hereunder.  The Board may require any Optionee,
 legal representative, heir, legatee or distributee, as a condition precedent
 to such payment, to execute a release and receipt therefor in such form as
 it shall determine.

           Stock Option Plan 
           BENCHMARQ Microelectronics, Inc. 1995 
           Flexible Stock Option Plan       
      
 Ladies and Gentlemen: 
  
           We have served as Maryland counsel to Unitrode Corporation, a
 Maryland corporation (the "Company"), in connection with certain matters of
 Maryland law arising out of the registration of 1,428,618 shares (the
 "Shares") of common stock par value $.01 per share of the Company ("Common
 Stock"), covered by the above-referenced Registration Statement (the
 "Registration Statement"), under the Securities Act of 1933, as amended
 (the "1933 Act").  The Shares are to be issued by the Company pursuant to
 the BENCHMARQ Microelectronics, Inc. 1989 Stock Option Plan and the
 BENCHMARQ Microelectronics, Inc. 1995 Flexible Stock Option Plan
 (collectively, the "Plans").  Outstanding options under the Plans were
 assumed by the Company pursuant to an Agreement and Plan of Merger, dated
 as of March 2, 1998, among the Company, Merrimack Corporation and BENCHMARQ
 Microelectronics, Inc.  Capitalized terms used but not defined herein shall
 have the meanings given to them in the Registration Statement. 
  
           In connection with our representation of the Company, and as a
 basis for the opinion hereinafter set forth, we have examined originals, or
 copies certified or otherwise identified to our satisfaction, of the
 following documents (hereinafter collectively referred to as the
 "Documents"): 
  
           1.   The Registration Statement, and all amendments thereto,
 filed with the Securities and Exchange Commission (the "Commission"),
 pursuant to the Securities Act of 1933, as amended (the "1933 Act");  
  
           2.   The Charter of the Company (the "Charter"), certified as of
 a recent date by the State Department of Assessments and Taxation of
 Maryland (the "SDAT"); 
  
           3.   The Bylaws of the Company, certified as of the date hereof
 by its Secretary; 
  
           4.   Resolutions adopted by the Board of Directors of the Company
 relating to the issuance and registration of the Shares, certified as of
 the date hereof by the Secretary of the Company; 
  
           5.   The Plans; 
  
           6.   A certificate of the SDAT as to the good standing of the
 Company, dated as of a recent date; 
  
           7.   A certificate executed by the Secretary of the Company,
 dated the date hereof; and 
  
           8.   Such other documents and matters as we have deemed necessary
 or appropriate to express the opinion set forth in this letter, subject to
 the assumptions, limitations and qualifications stated herein. 
  
           In expressing the opinion set forth below, we have assumed, and
 so far as is known to us there are no facts inconsistent with, the
 following: 
  
           1.   Each individual executing any of the Documents, whether on
 behalf of such individual or another person, is legally competent to do so. 
  
           2.   Each individual executing any of the Documents on behalf of
 a party (other than the Company) is duly authorized to do so. 
  
           3.   Each of the parties (other than the Company) executing any
 of the Documents has duly and validly executed and  delivered each of the
 Documents to which such party is a signatory, and such party's obligations
 set forth therein are legal, valid and binding and are enforceable in
 accordance with all stated terms. 
  
           4.  Any Documents submitted to us as originals are authentic. 
 The form and content of the Documents submitted to us as unexecuted drafts
 do not differ in any respect relevant to this opinion from the form and
 content of such Documents as executed and delivered.  Any Documents
 submitted to us as certified or photostatic copies conform to the original
 documents.  All signatures on all such Documents are genuine.  All public
 records reviewed or relied upon by us or on our behalf are true and
 complete.  All statements and information contained in the Documents are
 true and complete.  There has been no oral or written modification of or
 amendment to any of the Documents, and there has been no waiver of any
 provision of any of the Documents, by action or omission of the parties or
 otherwise.  
  
           The phrase "known to us" is limited to the actual knowledge,
 without independent inquiry, of the lawyers at our firm who have performed
 legal services in connection with the issuance of this opinion. 
  
           Based upon the foregoing, and subject to the assumptions,
 limitations and qualifications stated herein, it is our opinion that: 
  
           1.   The Company is a corporation duly incorporated and existing
 under and by virtue of the laws of the State of Maryland and is in good
 standing with the SDAT. 
  
           2.   The Shares have been duly authorized for issuance pursuant
 to the Plans and, when and if issued and delivered against payment therefor
 and otherwise in the manner described in the Resolutions and the Plans,
 will be (assuming that upon any such issuance the total number of shares of
 Common Stock issued and outstanding will not exceed the total number of
 shares of Common Stock that the Company is then authorized to issue under
 the Charter) validly issued, fully paid and nonassessable. 
  
           The foregoing opinion is limited to the substantive laws of the
 State of Maryland and we do not express any opinion herein concerning any
 other law.  We express no opinion as to compliance with any federal or
 state securities laws, including the securities laws of the State of
 Maryland.  We assume no obligation to supplement this opinion if any
 applicable law changes after the date hereof or if we become aware of any
 fact that might change the opinion expressed herein after the date hereof. 
  
           This opinion is being furnished to you for submission to the
 Commission as an exhibit to the Registration Statement and, accordingly,
 may not be relied upon by, quoted in any manner to, or delivered to any
 other person or entity without, in each instance, our prior written
 consent. 
  
           We hereby consent to the filing of this opinion as an exhibit to
 the Registration Statement and to the use of the name of our firm therein. 
 In giving this consent, we do not admit that we are within the category of
 persons whose consent is required by Section 7 of the 1933 Act. 
  
                               Very truly yours, 
  

                               /s/ Ballard Spahr Andrews & Ingersoll, LLP
