 1    955,158 of the shares of Issuer common stock covered by this report
      are purchasable by the Reporting Person upon exercise of an option
      granted to the Reporting Person as of March 2, 1998, and described in
      Item 4 of this report.  Prior to the exercise of the option, the
      Reporting Person is not entitled to any rights as a stockholder of
      Issuer as to the shares covered by the option.  The option may only be
      exercised upon the happening of certain events referred to in Item 4,
      none of which has occurred as of the date hereof.  The Reporting
      Person expressly disclaims beneficial ownership of any of the shares
      of common stock of Issuer which are purchasable by the Reporting
      Person upon exercise of the option until such time as the Reporting
      Person purchases any such shares upon any such exercise.  The number
      of shares indicated represents 13.4% of the total outstanding shares
      of common stock of Issuer as of March 2, 1998, excluding shares
      issuable upon exercise of the option. 
  
 2    1,460,609 of the shares of the Issuer common stock covered by this
      report are subject to a Voting Agreement entered into by certain
      stockholders of the Issuer with the Reporting Person pursuant to which
      such stockholders have agreed to vote all of the shares beneficially
      owned by such stockholders in favor of certain matters, including
      without limitation the proposed merger of Merrimack Corporation, a
      wholly owned subsidiary of the Reporting Person, with and into the
      Issuer, and against, among other things, any action or agreement that
      could reasonably be executed to result, directly or indirectly, in a
      breach in any material respect of any covenant, representation or
      warranty or any obligation of the Issuer under the Agreement and Plan
      of Merger dated as of March 2, 1998 between the Issuer, Merrimack
      Corporation and the Reporting Person described in Item 3 hereof.  The
      Reporting Person expressly disclaims beneficial ownership of any of
      the shares of Issuer common stock covered by the Voting Agreement. 
      The number of shares indicated represents approximately 20.6% of the
      outstanding shares of common stock of the Issuer as of March 2, 1998,
      excluding the shares issuable upon exercise of the Option (as
      described above).   
  
 3    After giving effect to the exercise of the option as described herein.


 ITEM 1.   SECURITY AND ISSUER. 
  
           This statement on Schedule 13D (the "Schedule 13D") relates to
 the common stock, par value $.001 per share (the "Shares" or the "Issuer
 Common Stock"), of BENCHMARQ Microelectronics, Inc., a Delaware corporation
 (the "Issuer").  The principal executive office of the Issuer is located at
 17919 Waterview Parkway, Dallas, Texas 75252. 
  
           The information set forth in the Exhibits hereto is hereby
 expressly incorporated herein by reference and the responses to each item
 of this Schedule 13D are qualified in their entirety by the provisions of
 such Exhibits. 

  
 ITEM 2.   IDENTITY AND BACKGROUND. 
  
           (a)-(c)  This Schedule 13D is filed by Unitrode Corporation, a
 Maryland corporation (the "Reporting Person"). 
  
           The business address of the Reporting Person is 7 Continental
 Boulevard, Merrimack, New Hampshire 03054.  The principal business of the
 Reporting Person is the design and manufacture of analog/linear integrated
 circuits. 
  
           To the best of the Reporting Person's knowledge as of the date
 hereof, the name, business address, present principal occupation or
 employment, name, principal business and address of any corporation or
 other organization in which such employment is conducted, and citizenship
 of each executive officer and director of the Reporting Person is set forth
 in Schedule I hereto.  The information contained in Schedule I is
 incorporated herein by reference. 
  
           (d)-(e)  During the last five years, neither the Reporting Person
 nor, to the best knowledge of the Reporting Person, any of the executive
 officers or directors of the Reporting Person, has been convicted in a
 criminal proceeding (excluding traffic violations or similar misdemeanors),
 or been a party to a civil proceeding of a judicial or administrative body
 of competent jurisdiction and as a result of such proceeding was or is
 subject to a judgment, decree or final order enjoining future violations
 of, or prohibiting or mandating activities subject to, Federal or State
 securities laws or finding any violation with respect to such laws.  

  
 ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. 
  
           The Reporting Person entered into an Agreement and Plan of Merger
 dated as of March 2, 1998 by and among the Reporting Person, Merrimack
 Corporation, a Delaware corporation and wholly owned subsidiary of the
 Reporting Person ("Merger Sub"), and the Issuer (the "Merger Agreement"),
 providing for the merger (the "Merger") of the Merger Sub with and into the
 Issuer with the Issuer as the surviving corporation, pursuant to which each
 outstanding Share will be converted into the right to receive shares of
 common stock, par value $0.01 per share, of the Reporting Person (the
 "Reporting Person Common Stock") and one associated preferred stock
 purchase right (a "Right") issued in accordance with the Rights Agreement
 (the "Rights Agreement"), dated as of May 2, 1990, as amended from time to
 time, between the Reporting Person and the First National Bank of Boston
 (references to shares of the Reporting Person Common Stock issuable in the
 Merger are deemed to include the associated Rights).  The Merger is subject
 to the approval of the Merger by the Issuer's stockholders, the approval by
 the Reporting Person's stockholders of the issuance of Reporting Person
 Common Stock in the Merger, the expiration of the applicable waiting period
 under the Hart-Scott- Rodino Antitrust Improvements Act of 1976, as
 amended, and any other required regulatory approvals, and the satisfaction
 or waiver of certain other conditions as more fully described in the Merger
 Agreement.  The foregoing summary of the Merger and the Merger Agreement is
 qualified in its entirety by reference to the Merger Agreement, a copy of
 which is included as Exhibit 1 to this Schedule 13D and is incorporated
 herein in its entirety by reference.   
  
           As a further inducement for the Reporting Person to enter into
 the Merger Agreement and in consideration thereof, Issuer and the Reporting
 Person entered into that certain Stock Option Agreement (the "Option
 Agreement"), dated as of March 2, 1998, whereby Issuer granted to the
 Reporting Person an option (the "Option") to purchase, under certain
 circumstances described therein, up to 955,158 Shares at a purchase price
 per Share equal to $17.53, as adjusted as provided therein (the "Purchase
 Price").  Based on the number of Shares outstanding on March 2, 1998, the
 Option would be exercisable for approximately 13.4% of the outstanding
 Shares, or approximately 10% of the Shares on a fully diluted basis after
 giving effect to the exercise of the Option.   
  
           None of the Triggering Events (defined in Item 4 below)
 permitting the exercise of the Option has occurred as of the date hereof. 
 In the event that the Option becomes exercisable and the Reporting Person
 wishes to purchase the Shares subject thereto, the Reporting Person
 anticipates that it would fund the exercise price with working capital or
 through other financing sources available to the Reporting Person at the
 time of exercise.  See also Item 4 below.   
  
           As a further inducement for the Reporting Person to enter into
 the Merger Agreement, Alan R. Schuele, Derrell C. Coker, L.J. Sevin, Harvey
 B. Cash, Dietrich Erdmann, Jack Kilby and Charles H. Phipps, stockholders
 of the Issuer (the "Stockholders") entered into a Voting Agreement (the
 "Voting Agreement"), dated as of March 2, 1998, with the Reporting Person
 whereby the Stockholders agreed to vote all of the Shares beneficially
 owned by them in favor of certain matters, including without limitation,
 the approval and adoption of the Merger Agreement, and against, among other
 things, any action or agreement that could reasonably be expected to
 result, directly or indirectly, in a breach in any material respect of any
 covenant, representation or warranty or any obligation of the Issuer under
 the Merger Agreement or the Option Agreement.  The Reporting Person did not
 pay additional consideration to any Stockholder in connection with the
 execution and delivery of the Voting Agreement.   

  
 ITEM 4.   PURPOSE OF THE TRANSACTION. 
  
           (a)-(j)  The information set forth in Item 3 is hereby
 incorporated herein by reference. 
  
           Pursuant to the Option Agreement, the Issuer has granted the
 Reporting Person the Option, which, based on the number of Shares
 outstanding on March 2, 1998, would be exercisable for approximately 13.4%
 of the outstanding Shares, or approximately 10% of the Shares on a fully
 diluted basis after giving effect to the exercise of the Option.   
  
           The Reporting Person may exercise the Option, in whole or in
 part, at any time and from time to time following the occurrence of certain
 events (each, a "Triggering Event"), provided that the Reporting Person
 provides notice of such exercise in accordance with the Option Agreement. 
 A Triggering Event includes the following:  
  
           (i) any Person (as defined in the Merger Agreement) (other than
      the Reporting Person or any subsidiary of the Reporting Person) shall
      have commenced (as such term is defined in Rule 14d-2 under the
      Securities Exchange Act of 1934, as amended (the "Exchange Act")) or
      shall have filed a registration statement under the Securities Act of
      1933, as amended (the "Securities Act"), with respect to a tender
      offer or exchange offer to purchase any shares of Issuer Common Stock
      such that, upon consummation of such offer, such Person would own or
      control 10% or more of the then outstanding Issuer Common Stock; 
  
           (ii) the Issuer or any subsidiary of the Issuer shall have
      authorized, recommended, proposed or publicly announced an intention
      to authorize, recommend or propose, or entered into, an agreement with
      any Person (other than the Reporting Person or any subsidiary of the
      Reporting Person) to (A) effect a merger, reorganization,
      consolidation, share exchange or other business combination or similar
      transaction involving the Issuer or any of its Significant
      Subsidiaries (within the meaning of Rule 1-02 of Regulation S-X of the
      Securities and Exchange Commission), (B) sell, lease or otherwise
      dispose of assets of the Issuer or its subsidiaries representing 10%
      or more of the consolidated assets of the Issuer other than in the
      ordinary course of business or (C) issue, sell or otherwise dispose of
      (including by way of merger, reorganization, consolidation, share
      exchange or other business combination or any similar transaction)
      securities (or options, rights or warrants to purchase, or securities
      convertible into or exchangeable for, such securities) representing
      10% or more of the voting power of the Issuer or any of its
      Significant Subsidiaries; or 
  
           (iii) any Person (other than the Reporting Person or any
      subsidiary of the Reporting Person or the Issuer or, in a fiduciary
      capacity, any subsidiary of the Issuer) shall have, subsequent to the
      date of the Option Agreement, acquired beneficial ownership (as such
      term is defined in Rule 13d-3 under the Exchange Act) or the right to
      acquire beneficial ownership of, or any "Group" (as such term is
      defined under the Exchange Act) shall have been formed which
      beneficially owns or has the right to acquire beneficial ownership of,
      10% or more of the then outstanding Issuer Common Stock. 
  
 provided, that the Option will terminate either (i)immediately prior to the
 Effective Time (as defined in the Merger Agreement) of the Merger; or (ii)
 at the time of termination of the Merger Agreement (A) by the Issuer or the
 Reporting Person pursuant to Subsection 9.1(d) of the Merger Agreement,
 provided that the matter giving rise to the Order (as defined in the Merger
 Agreement) providing the basis for termination under Subsection 9.1(d) of
 the Merger Agreement shall not have been initiated by the Issuer or any
 Person who initiates an Acquisition Proposal (as such item is defined in
 the Merger Agreement), (B) by the Issuer pursuant to Subsection 9.1(c),
 Subsection 9.1(h) or Subsection 9.1(j) of the Merger Agreement, (C) by
 either the Issuer or the Reporting Person pursuant to Subsection 9.1(g) of
 the Merger Agreement, (D) by both the Issuer and the Reporting Person
 pursuant to Subsection 9.1(a) of the Merger Agreement, (E) by the Issuer or
 the Reporting Person pursuant to Subsection 9.1(e) of the Merger Agreement
 (if there then exists circumstances that would permit termination of the
 Merger Agreement by the Issuer pursuant to Subsection 9.1(e) of the Merger
 Agreement), (F) by the Reporting Person pursuant to Subsection 9.1(i)(i)
 (if circumstances exist that would allow the Issuer to terminate the Merger
 Agreement pursuant to Subsection 9.1(h) of the Merger Agreement) or (G) by
 either party pursuant to any other provision of the Merger Agreement;
 provided (in the case of subsection (G)) such termination occurs prior to
 the occurrence of an Acquisition Proposal. 
  
           Upon the occurrence of certain events set forth in the Option
 Agreement, the Issuer is required to repurchase the Option (the
 "Repurchase") or to cause the Option to be converted into, or exchanged
 for, an option of another corporation (the "Substitute Option").  In
 addition, the Option Agreement grants certain registration rights (the
 "Registration Rights") to the Reporting Person with respect to the Shares
 represented by the Option.  Also, under certain circumstances, the Issuer
 is entitled to a right of first refusal (the "Right of First Refusal") if
 the Reporting Person desires to sell all or any part of the Option or
 Shares acquired by it pursuant thereto.  Notwithstanding any other
 provisions of the Option Agreement, the Total Profit (as defined therein)
 which the Reporting Person may realize from the Option may not exceed
 $7,278,000.  The terms of such Repurchase, Substitute Option, Registration
 Rights, Right of First Refusal and limitations on Total Profit are set
 forth in the Option Agreement.  The foregoing summary of the Option
 Agreement is qualified in its entirety by reference to the copy of the
 Option Agreement included as Exhibit 2 of this Schedule 13D and
 incorporated herein in its entirety by reference.  
  
           Pursuant to the Voting Agreement, the Stockholders agreed to vote
 all of the Shares beneficially owned by them in favor of certain matters,
 including without limitation, the approval and adoption of the Merger
 Agreement, and against, among other things, any action or agreement that
 could reasonably be expected to result, directly or indirectly, in a breach
 in any material respect of any covenant, representation or warranty or any
 obligation of the Issuer under the Merger Agreement or the Option
 Agreement.  The Voting Agreement terminates upon the earlier to occur of
 the Effective Time or the termination of the Merger Agreement.  The name of
 each Stockholder and the number of outstanding shares of Issuer Common
 Stock held by each Stockholder are set forth on Schedule A to the Voting
 Agreement which is incorporated herein by reference.  The foregoing summary
 of the Voting Agreement is qualified in its entirety by reference to the
 copy of the Voting Agreement included as Exhibit 3 of this Schedule 13D and
 incorporated herein in its entirety by reference.  
  
           The purpose of the Option Agreement and the Voting Agreement are
 to facilitate consummation of the Merger. 
  
           Upon consummation of the Merger as contemplated by the Merger
 Agreement, (a) a new subsidiary of the Reporting Person will be merged into
 the Issuer, (b) the Board of Directors of the Issuer will be replaced by
 the Board of Directors of Merger Sub, (c) the Certificate of Incorporation
 and Bylaws of the Issuer will be replaced by the Certificate of
 Incorporation and Bylaws of the Merger Sub, (d) the Shares will cease to be
 authorized for listing on the Nasdaq National Market and (e) the Shares

 12(g)(4) of the Exchange Act. 

  
 ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER. 
  
           (a)-(b)  The number of Shares covered by the Option is 955,158,
 which constitutes approximately (i) 13.4% of Issuer Common Stock based on
 the Shares issued and outstanding on March 2, 1998, or (ii) 10% of the
 shares of Issuer Common Stock that would be outstanding after giving effect

           Prior to the exercise of the Option, the Reporting Person (i) is
 not entitled to any rights as a stockholder of Issuer as to the Shares
 covered by the option and (ii) disclaims any beneficial ownership of the
 shares of Issuer Common Stock which are purchasable by the Reporting Person
 upon exercise of the Option because the Option is exercisable only in the
 limited circumstances referred to in Item 4 above, none of which has
 occurred as of the date hereof.  If the Option were exercised, the
 Reporting Person would have the sole right to vote or to dispose of the
 shares of Issuer Common Stock issued as a result of such exercise. 
  
           The number of Shares covered by the Voting Agreement is
 1,460,609, which constitutes approximately 20.6% of the Issuer Common
 Stock, based on the number of Shares outstanding as of March 2, 1998.   
  
           The Reporting Person (i) is not entitled to any rights as a
 stockholder of Issuer as to the Shares covered by the Voting Agreement and
 (ii) disclaims any beneficial ownership of the shares of Issuer Common
 Stock which are by the Voting Agreement.  
  
           (c)  Other than as set forth in this Item 5, to the best of the
 Reporting Person's knowledge as of the date hereof (i) neither the
 Reporting Person nor any subsidiary or affiliate of the Reporting Person
 nor any of the Reporting Person's executive officers or directors,
 beneficially owns any shares of Issuer Common Stock, and (ii) there have
 been no transactions in the shares of Issuer Common Stock effected during
 the past 60 days by the Reporting Person, nor to the best of the Reporting
 Person's knowledge, by any subsidiary or affiliate of the Reporting Person
 or any of the Reporting Person's executive officers of directors. 
  
           (d)  No other person is known by the Reporting Person to have the
 right to receive or the power to direct the receipt of dividends from, or
 the proceeds from the sale of, the Issuer Common Stock obtainable by the
 Reporting Person upon exercise of the Option. 
  
           (e)  Not applicable. 

  
 ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
           RESPECT TO SECURITIES OF THE ISSUER. 
  
      Copies of the Merger Agreement, the Option Agreement and the Voting
 Agreement are attached as Exhibits hereto and, to the best of the Reporting
 Person's knowledge, there are at present no contracts, arrangements,
 understandings or relationship (legal or otherwise) among the persons named

      THIS AGREEMENT AND PLAN OF MERGER, dated as of March 2, 1998 is by and
 among Unitrode Corporation, a Maryland corporation (the "Acquiror"),
 Merrimack Corporation, a Delaware corporation and a wholly-owned subsidiary
 of Acquiror ("Newco"), and BENCHMARQ Microelectronics, Inc., a Delaware
 corporation (the "Company").  The Acquiror and Newco are sometimes referred
 to herein as the "Acquiror Companies." 
  
                                 RECITALS: 
       
      The Board of Directors of the Company has determined that the business
 combination to be effected by means of the Merger (as defined herein) is
 consistent with and in furtherance of the long-term strategic interests of
 the Company and is fair to, and in the best interests of, the Company and
 its stockholders and has approved and adopted this Agreement (as defined
 herein) and recommends approval and adoption of this Agreement by the
 stockholders of the Company. 
  
      The Board of Directors of the Acquiror has determined that the
 business combination to be effected by means of the Merger is consistent
 with and in furtherance of the long-term strategic interests of the
 Acquiror and in the best interests of, the Acquiror and its stockholders
 and has approved this Agreement and recommends approval by the stockholders
 of the Acquiror of the issuance of shares of the common stock, $.01 par
 value, of the Acquiror (the "Acquiror Common Stock") contemplated by the
 Merger. 
  
      The Board of Directors of Newco has determined that the business
 combination to be effected by means of the Merger is advisable, and in the
 best interests of, Newco and its stockholder and has approved and adopted
 this Agreement.  The stockholder of Newco has approved and adopted this
 Agreement.   
  
      Concurrently with the execution and delivery of this Agreement, as an
 essential condition and inducement to the willingness of the Acquiror and
 Newco to enter into this Agreement, certain holders of common stock, par
 value $.001 per share, of the Company  ("Company Common Stock") have each
 entered into a Voting Agreement (the "Voting Agreement") in the form
 attached as Annex A dated as of the date hereof pursuant to which such
 holders have agreed to vote their shares of Company Common Stock in the
 manner set forth therein. 
  
      Concurrently with the execution and delivery of this Agreement, as an
 essential condition and inducement to the willingness of the Acquiror and
 Newco to enter into this Agreement, the Company has entered into a Stock
 Option Agreement (the "Option Agreement") in the form attached hereto as
 Annex B dated as of the date hereof granting the Acquiror an irrevocable
 option to purchase up to 955,158 shares of the Company Common Stock on the
 terms and subject to the conditions set forth therein. 
  
      Upon the terms and subject to the conditions of this Agreement and in
 accordance with the Delaware General Corporation Law (the "DGCL"), Newco
 will merge with and into the Company (the "Merger") and the Company will
 continue as the surviving corporation (the "Surviving Corporation"). 
  
      For U.S. federal income tax purposes, it is intended that the Merger
 will qualify as a reorganization within the meaning of the provisions of
 Section 368(a) of the Internal Revenue Code of 1986, as amended (the
 "Code"), and that this Agreement shall be, and is hereby, adopted as a plan
 of reorganization for purposes of Section 368(a) of the Code. 
  
      The Merger is intended to be treated as a "pooling of interests" for
 accounting purposes. 
  
      NOW, THEREFORE, in consideration of the foregoing and the respective
 representations, warranties, covenants and agreements set forth in this
 Agreement, and intending to be legally bound hereby the parties hereto
 agree as follows:

           (c)  Notwithstanding any provision of this Agreement to the
      contrary, each share of Company Common Stock held in the treasury of
      the Company and each share of Company Common Stock, if any, owned by
      the Acquiror or any direct or indirect wholly-owned Subsidiary of the
      Acquiror or of the Company immediately prior to the Effective Time
      will be cancelled. 
  
           (d)  Each share of common stock, par value $.01 per share, of
      Newco issued and outstanding immediately prior to the Effective Time
      shall be converted into and become one fully paid and nonassessable
      share of common stock, par value $.01 per share, of the Surviving
      Corporation. 
  
      Section 3.2    Adjustments to the Exchange Ratio.  The Exchange Ratio
 shall be subject to adjustment as follows: 
  
           (a)  if the average of the mean high and low per share trading
      prices on the NYSE of shares of Acquiror Common Stock (as reported for
      the NYSE Composite Transactions in the Wall Street Journal) during the


      20 consecutive trading days ending on the tenth day prior to the
      Company Stockholders' Meeting (the "Pre-Closing Average Price") is
      less than $16.00, then the Exchange Ratio shall be adjusted such that
      each share of Company Common Stock is converted into the right to
      receive a number of shares of Acquiror Common Stock (and the 
      associated Acquiror Rights)  equal to the quotient obtained by
      dividing (i) $16.00 by (ii) the Pre-Closing Average Price, provided,
      however, that, the Exchange Ratio shall in no event be higher than
      1.33; and  
  
           (b)       if the Pre-Closing Average Price is greater than
      $24.00, then the Exchange Ratio shall be adjusted such that each share
      of Company Common Stock is converted into the right to receive a
      number of shares of Acquiror Common Stock (and the associated Acquiror
      Rights) equal to the quotient obtained by dividing (i) $24.00 by (ii)
      the Pre-Closing Average Price. 
  
      Section 3.3    Exchange of Certificates. 
  
           (a)  Exchange Fund.  On the Closing Date, the Acquiror will
      deposit, or cause to be deposited, with the Exchange Agent, for the
      benefit of the former holders of Company Common Stock, for exchange in
      accordance with this Article III, through the Exchange Agent,
      (i) certificates evidencing a number of shares of Acquiror Common
      Stock (and the associated Acquiror Rights) equal to the product of the
      Exchange Ratio multiplied by the number of shares of Company Common
      Stock issued and outstanding immediately prior to the Effective Time 
      (exclusive of any such shares to be cancelled pursuant to
      Subsection 3.1(c)) and (ii) cash in an amount equal to any dividends
      or other distributions declared in respect of such shares of Acquiror
      Common Stock and having a record date after the Effective Time. 
      Thereafter, the Acquiror will deposit, or cause to be deposited, with
      the Exchange Agent, for the benefit of any former holders of Company
      Common Stock who have not yet surrendered their shares of Company
      Common Stock for exchange, at the appropriate payment date, the amount
      of dividends or other distributions, with a record date after the
      Effective Time but prior to surrender, payable with respect to any
      shares of Acquiror Common Stock remaining in the Exchange Fund on such
      record date.  The Exchange Agent will, pursuant to irrevocable
      instructions from the Acquiror, deliver Acquiror Common Stock (and
      associated Acquiror Rights) and any dividends or distributions related
      thereto, in exchange for certificates theretofore evidencing Company
      Common Stock surrendered to the Exchange Agent pursuant to
      Subsection 3.3(c).   
  
           (b)  Letter of Transmittal.  Promptly after the Effective Time,
      the Acquiror will cause the Exchange Agent to mail to each record
      holder of a certificate or certificates representing Company Common
      Stock immediately prior to the Effective Time (i) a letter of
      transmittal which shall specify that delivery shall be effected, and
      risk of loss and title to the certificates for Company Common Stock
      shall pass, only upon delivery of the certificates for Company Common
      Stock to the Exchange Agent and shall be in such form and have such
      other provisions, including appropriate provisions with respect to
      back-up withholding, as the Acquiror may reasonably specify, and (ii)
      instructions for use in effecting the surrender of the certificates
      for Company Common Stock.  Upon surrender of a certificate for Company
      Common Stock for cancellation to the Exchange Agent, together with
      such letter of transmittal, duly executed and completed in accordance
      with the instructions thereto, the holder thereof shall be entitled to
      receive in exchange therefor that portion of the Exchange Fund which


      such holder has the right to receive pursuant to the provisions of
      this Article III, after giving effect to any required withholding tax,
      and the certificate for Company Common Stock so surrendered shall
      forthwith be cancelled.  No interest will be paid or accrued on the
      cash, if any, to be paid which is in the Exchange Fund as part of the
      Exchange Ratio.  
  
           (c)  Exchange Procedures.  Promptly after the Effective Time, the
      Exchange Agent will distribute to each former holder of Company Common
      Stock, upon surrender to the Exchange Agent for cancellation of one or
      more certificates, accompanied by a duly executed letter of
      transmittal that theretofore evidenced shares of Company Common Stock,
      certificates evidencing the appropriate number of shares of Acquiror
      Common Stock (and the associated Acquiror Rights) into which such
      shares of Company Common Stock were converted pursuant to the Merger
      and any dividends or distributions related thereto. If shares of
      Acquiror Common Stock (and the associated Acquiror Rights) are to be
      issued to a Person other than the Person in whose name the surrendered
      certificate or certificates are registered, it will be a condition of
      issuance of the Acquiror Common Stock (and the associated Acquiror
      Rights) that the surrendered certificate or certificates shall be
      properly endorsed, with signatures guaranteed by a member firm of the
      NYSE or a bank chartered under the Laws of the United States of
      America, or otherwise in proper form for transfer and that the Person
      requesting such payment shall pay any transfer or other taxes required
      by reason of the issuance of Acquiror Common Stock (and the associated
      Acquiror Rights) to a Person other than the registered holder of the
      surrendered certificate or certificates or such Person shall establish
      to the satisfaction of the Acquiror that any such tax has been paid or
      is not applicable.  Notwithstanding the foregoing, neither the
      Exchange Agent nor any party hereto will be liable to any former
      holder of Company Common Stock for any Acquiror Common Stock (and the
      associated Acquiror Rights) or dividends or distributions thereon
      delivered to a public official pursuant to any applicable escheat Law. 
  
           (d)  Distributions with Respect to Unexchanged Shares of Company
      Common Stock.  No dividends or other distributions declared or made
      with respect to Acquiror Common Stock with a record date on or after
      the Effective Time will be paid to the holder of any certificate that
      theretofore evidenced shares of Company Common Stock until the holder
      of such certificate shall surrender such certificate.  Subject to the
      effect of any applicable escheat Law, following surrender of any such
      certificate, there will be paid from the Exchange Fund to the holder
      of the certificates evidencing whole shares of Acquiror Common Stock
      (and the associated Acquiror Rights) issued in exchange therefor,
      without interest, (i) promptly, the amount of dividends or other
      distributions with a record date after the Effective Time theretofore
      paid with respect to such whole shares of Acquiror Common Stock, and
      (ii) at the appropriate payment date, the amount of dividends or other
      distributions, with a record date after the Effective Time but prior
      to surrender and a payment date occurring after surrender, payable
      with respect to such whole shares of Acquiror Common Stock. 
  
           (e)  Termination of Exchange Fund.  Any portion of the Exchange
      Fund which remains unclaimed by the former holders of Company Common
      Stock for twelve months after the Effective Time will be delivered to
      the Acquiror, upon demand, and any former holders of Company Common
      Stock who have not theretofore complied with this Article III will,
      subject to applicable abandoned property, escheat and other similar
      Laws, thereafter look only to the Acquiror for the Acquiror Common



      Stock (and associated Acquiror Rights) and any cash to which they are
      entitled. 
  
           (f)  Withholding of Tax.  The Acquiror or the Exchange Agent will
      be entitled to deduct and withhold from the consideration otherwise
      payable pursuant to this Agreement to any former holder of Company
      Common Stock such amounts as the Acquiror (or any affiliate thereof)
      or the Exchange Agent are required to deduct and withhold with respect
      to the making of such payment under the Code, or any provision of
      state, local or foreign tax Law.  To the extent that amounts are so
      withheld by the Acquiror or the Exchange Agent, such withheld amounts
      will be treated for all purposes of this Agreement as having been paid
      to the former holder of Company Common Stock in respect of which such
      deduction and withholding were made by the Acquiror. 
  
           (g)  Lost Certificates.  If any certificate evidencing Company
      Common Stock shall have been lost, stolen or destroyed, upon the
      making of an affidavit of that fact by the Person claiming such
      certificate to be lost, stolen or destroyed and, if required by the
      Acquiror, the posting by such Person of a bond, in such reasonable
      amount as the Acquiror may direct, as indemnity against claims that
      may be made against it with respect to such certificate, the Exchange
      Agent will issue in exchange for such lost, stolen or destroyed
      certificate the Acquiror Common Stock (and associated Acquiror Rights)
      to which the holder may be entitled pursuant to this Article III and
      any dividends or other distributions to which the holder thereof may
      be entitled pursuant to Subsection 3.3(d). 
  
      Section 3.4    Closing.  The Closing will take place at the offices of
 Skadden, Arps, Slate, Meagher & Flom LLP, One Beacon Street, Boston,
 Massachusetts 02108, at 10:00 a.m. local time on the second Business Day
 following the date on which the conditions to the Closing have been
 satisfied or waived or at such other place, time and date as the parties
 hereto may agree.  At the conclusion of the Closing on the Closing Date,
 the parties hereto will cause the Certificate of Merger to be filed with
 the Secretary of State of the State of Delaware. 
  
      Section 3.5    Stock Transfer Books.  At the Effective Time, the stock
 transfer books of the Company will be closed and there will be no further
 registration of transfers of shares of Company Common Stock thereafter on
 the records of the Company.  If, after the Effective Time, certificates
 representing Company Common Stock are presented to the Surviving
 Corporation, they shall be cancelled and upon delivery of a duly executed
 letter of transmittal exchanged for certificates representing Acquiror
 Common Stock (and associated Acquiror Rights). 
  
      Section 3.6    No Fractional Shares.  In the event the Exchange Ratio
 is modified or changed in a manner that would result in the issuance of
 fractional shares of Acquiror Common Stock, the parties nevertheless agree
 that no fractional shares of Acquiror Common Stock shall be issued to the
 holders of Company Common Stock.  In lieu of any such fractional shares,
 each holder of record of Company Common Stock at the Effective Time who but
 for the provisions of this Section 3.6 would be entitled to receive a
 fractional share of Acquiror Common Stock pursuant to the Merger shall be
 paid cash, without any interest thereon, in an amount equal to the product
 of such fraction multiplied by the closing sale price of one share of
 Acquiror Common Stock on the NYSE on the day of the Effective Time, or, if
 shares of Acquiror Common Stock are not so traded on such day, the closing
 sale price of one such share on the next preceding day on which such share
 was traded on the NYSE.  For this purpose, shares of Company Common Stock
 of any holder represented by two or more certificates may be aggregated,


 and in no event shall any holder be paid an amount in respect of more than
 one share of Acquiror Common Stock. 

  
                                 ARTICLE IV

      Disclosure Letter, there are no voting trusts, proxies or other
      agreements, commitments or understandings of any character to which

 Material Adverse Effect on the Company.  Prior to the execution of this
 Agreement, the Board of Directors of the Company has taken all requisite

      Commission and (ii) all other Reports required to be filed with any
      other Governmental Authorities, including state securities
      administrators, except where the failure to file any such Reports
      would not in the aggregate have a Material Adverse Effect on the
      Company.  Such Reports, including all those filed after the date of
      this Agreement and prior to the Effective Time, (i) were prepared in
      all Material respects in accordance with the requirements of

           (c)  Except as set forth in Subsection 4.7(c) of the Company's
      Disclosure Letter, there exist no liabilities or obligations of the
      Company and its Subsidiaries that are Material to the Company, whether
      accrued, absolute, contingent or threatened, which would be required
      to be reflected, reserved for or disclosed under GAAP in consolidated
      financial statements of the Company (including the notes thereto) as
      of and for the period ended on the date of this representation and

           (a)  Since December 31, 1996, (i) no event or events (other than
      any event that is directly attributable to the prospect of

 Except as set forth in Section 4.14 of the Company's Disclosure Letter, the
 Company represents and warrants as follows: 
  
           (a)  Pension Plans. 
  
                (i)   No "accumulated funding deficiency" (for which an
           excise tax is due or would be due in the absence of a waiver) as
           defined in section 412 of the Code or as defined in Section
           302(a)(2) of ERISA, whichever may apply, has been incurred with


           respect to any Pension Plan of the Company or any ERISA Affiliate
           thereof with respect to any plan year, whether or not waived. 
           Neither the Company nor any ERISA Affiliate thereof has failed to
           pay when due any "required installment," within the meaning of
           section 412(m) of the Code and Section 302(e) of ERISA, whichever
           may apply, with respect to any such Pension Plan.  Neither the
           Company nor any ERISA Affiliate thereof is subject to any Lien
           imposed under section 412(n) of the Code or Section 302(f) or
           4068 of ERISA, whichever may apply, with respect to any such
           Pension Plan.  All "benefit liabilities" within the meaning of
           Section 4001(a)(16) of ERISA, are fully funded as of the Closing
           Date with respect to each such Pension Plan as determined on a
           termination basis using the assumed interest rate set forth in
           each Pension Plan. 
  
                (ii)   Neither the Company nor any ERISA Affiliate thereof is
           required to provide security to a Pension Plan under section
           401(a)(29) of the Code. 
  
               (iii)   Except as otherwise disclosed in Subsection
           4.14(a) of the Company's Disclosure Letter, each Pension Plan of
           the Company or any ERISA Affiliate thereof and each related trust
           agreement, annuity contract or other funding instrument is
           qualified and tax exempt under the provisions of Code sections
           401(a) and 501(a), and each has been so determined by the IRS, or
           application for such determination has been made and is currently
           pending.  Any such Pension Plan that has been terminated has
           received a favorable determination letter from the IRS with
           respect to its termination, or application for such determination
           has been made and is currently pending. 
  
                (iv) Each Pension Plan of the Company or any ERISA Affiliate
           thereof, related trust agreement, annuity contract or other
           funding instrument is in Material compliance with its terms and,
           both as to form and in operation, with the requirements
           prescribed by any and all Laws which are applicable to such
           Pension Plan, related trust agreement, annuity contract or other
           funding instrument, including without limitation ERISA and the
           Code. 
  
                (v)  The Company or an ERISA Affiliate thereof has paid all
           premiums (and interest charges and penalties for late payment, if
           applicable) due to the PBGC with respect to each Pension Plan of
           the Company or any ERISA Affiliate thereof which is covered by
           Title IV of ERISA for each plan year thereof for which such
           premiums are required.  Neither the Company nor any ERISA
           Affiliate thereof has engaged in, or is a successor or parent
           corporation to an entity that has engaged in, a transaction which
           is described in Section 4069 of ERISA.  There has been no
           unreported "reportable event" (as defined in Section 4043(b) of
           ERISA and the PBGC regulations under such Section) requiring
           notice to the PBGC with respect to any Pension Plan of the
           Company or any ERISA Affiliate thereof.  No filing has been made
           by the Company or any ERISA Affiliate thereof with the PBGC, and
           no proceeding has been commenced by the PBGC, to terminate any
           Pension Plan of the Company or any ERISA Affiliate thereof.  No
           condition exists and no event has occurred that could constitute
           grounds for the termination of any Pension Plan of the Company or
           any ERISA Affiliate thereof by the PBGC, or which could
           reasonably be expected to result in liability of the Company or
           any ERISA Affiliate thereof to the PBGC with respect to any such


           Pension Plan, other than liabilities for premium payments. 
           Neither the Company nor any ERISA Affiliate thereof has, at any
           time, (1) ceased operations at a facility so as to become subject
           to the provisions of Section 4062(e) of ERISA, (2) withdrawn as a
           substantial employer so as to become subject to the provisions of
           Section 4063 of ERISA, or (3) ceased making contributions to any
           Pension Plan of the Company or any ERISA Affiliate thereof
           subject to Section 4064(a) of ERISA to which the Company or any
           ERISA Affiliate thereof made contributions during the six (6)
           years prior to the date hereof. 
  
           (b)  Multiemployer Plans.  There are no Multiemployer Plans of
      the Company or any ERISA Affiliate thereof, and neither the Company
      nor any ERISA Affiliate thereof has ever maintained, contributed to,
      or participated or agreed to participate in any Multiemployer Plan. 
  
           (c)  Welfare Plans. 
  
                (i)  Each Welfare Plan of the Company or any ERISA Affiliate
           thereof is in Material compliance with its terms and, both as to
           form and operation, with the requirements prescribed by any and
           all Laws which are applicable to such Welfare Plan, including
           without limitation ERISA and the Code. 
  
                (ii) An estimate of the liabilities of the Company and any
           of its ERISA Affiliates for providing retiree life and medical
           benefits coverage to active and retired employees of the Company
           and any of its ERISA Affiliates has been made and is reflected on
           the appropriate balance sheet and books and records according to
           Statement of Financial Accounting Standards No. 106.  The Company
           or any ERISA Affiliate thereof has the right to modify or
           terminate any Welfare Plans of the Company or any ERISA Affiliate
           thereof that provide coverage or benefits for either or both
           retired and active employees and/or their dependents and
           beneficiaries. 
  
                (iii) Each Welfare Plan of the Company or any ERISA
           Affiliate thereof which is a "group health plan," as defined in
           Section 607(1) of ERISA, has been operated in material compliance
           at all times with the provisions of Parts 6 and 7 of Title I,
           Subtitle B of ERISA and sections 4980B and 9801 through 9806 of
           the Code. 
  
                (iv) There are no Welfare Plans of the Company or any ERISA
           Affiliate thereof which are self-insured "multiple employer
           welfare arrangements" as such term is defined in Section 3(40) of
           ERISA. 
  
           (d)  Benefit Arrangements. 
  
                (i)  Each Benefit Arrangement of the Company or any ERISA
           Affiliate thereof is in Material compliance with its terms and
           with the requirements prescribed by any and all Laws which are
           applicable to such Benefit Arrangement, including without
           limitation the Code. 
  
                (ii) Except as set forth in Subsection 4.14(d) of the
           Company's Disclosure Letter, neither the Company nor any ERISA
           Affiliate thereof is a party to or is bound by any severance
           agreement, plan, or program  (other than such an agreement, plan,



           or program providing for payments of less than $50,000 in the
           aggregate to all participants). 
  
               (iii)  Each outstanding Company Stock Options not vested
           or exercisable at the Effective Time shall, as a result of the
           transactions contemplated hereby, automatically and without any
           action by the Company or the Board of Directors of the Company,
           become vested and exercisable at the Effective Time. 
       
           (e)  Fiduciary Duties and Prohibited Transactions.  Neither the
      Company nor any ERISA Affiliate thereof has any liability with respect
      to any transaction in violation of Sections 404 or 406 of ERISA or any
      "prohibited transaction," as defined in section 4975(c)(1) of the
      Code, for which no exemption exists under Section 408 of ERISA or
      section 4975(c)(2) or (d) of the Code to which any Welfare Plan or
      Pension Plan of the Company or any ERISA Affiliate thereof is subject. 
      To the Knowledge of the Company, neither the Company nor any ERISA
      Affiliate thereof has participated in a violation of Part 4 of
      Title I, Subtitle B of ERISA by any plan fiduciary of any Welfare Plan
      or Pension Plan of the Company or any ERISA Affiliate thereof or has
      any unpaid civil penalty under Section 502(1) of ERISA. 
  
           (f)  Litigation.  There is no Material action, Order or claim,
      suit, litigation, proceeding, arbitral action, governmental audit or
      investigation relating to or seeking benefits under any Employee Plan
      of the Company or any ERISA Affiliate thereof that is pending or, to
      the Knowledge of the Company, threatened or anticipated against the
      Company or any ERISA Affiliate thereof other than routine claims for
      benefits. 
  
           (g)  Unpaid Contributions.  Neither the Company nor any ERISA

      in Subsection 4.14(h) of the Company's Disclosure Letter, the
      execution of this Agreement and the consummation of the transactions
      contemplated hereby will not, either alone or in connection with
      another event, result in any payment (whether of separation pay or
      otherwise) becoming due from the Company or any ERISA Affiliate
      thereof (under an Employee Plan of the Company or any ERISA Affiliate
      thereof or otherwise) to any current or former employee or consultant

      any liability under the terms of such Employee Plans, ERISA, the Code,
      or any other applicable Law, other than any condition or set of

      the Proxy Statement will be made by the Acquiror or the Company
      without prior consultation with the other party.  The Acquiror and the
      Company each will advise the other, promptly after it receives notice


      thereof, of the time when the Registration Statement has become
      effective or any supplement or amendment has been filed, the issuance
      of any stop order suspending the effectiveness of the Registration
      Statement or the solicitation of proxies pursuant to the Proxy
      Statement, the suspension of the qualification of the Acquiror Common
      Stock issuable in connection with the Merger for offering or sale in
      any jurisdiction, any request by the staff of the Commission for
      amendment of the Registration Statement or the Proxy Statement, the
      receipt from the staff of the Commission of comments thereon or any
      request by the staff of the Commission for additional information with
      respect thereto. 
  
      Section 7.3    Appropriate Action; Consents; Filings. 
  
           (a)  The Company and the Acquiror will each use all reasonable
      efforts (i) to take, or to cause to be taken, all appropriate action,
      and to do, or to cause to be done, all things necessary, proper or
      advisable under applicable Law or otherwise to consummate and make
      effective the transactions contemplated by this Agreement, (ii) to
      obtain from any Governmental Authorities any Permits or Orders
      required to be obtained by the Acquiror or the Company or any of their
      Subsidiaries in connection with the authorization, execution, delivery
      and performance of this Agreement and the consummation of the
      transactions contemplated hereby, including the Merger, (iii) to make
      all necessary filings, and thereafter make any other required
      submissions, with respect to this Agreement and the Merger required
      under (A) the Securities Act and the Exchange Act, and any other
      applicable federal or state securities Laws, (B) the HSR Act, and
      (C) any other applicable Law; provided that the Acquiror and the
      Company will cooperate with each other in connection with the making
      of all such filings, including providing copies of all such documents
      to the nonfiling party and its advisors prior to filings and, if
      requested, will accept all reasonable additions, deletions or changes
      suggested in connection therewith.  The Company and the Acquiror will
      furnish all information required for any application or other filing
      to be made pursuant to any applicable Law or any applicable
      Regulations of any Governmental Authority (including all information
      required to be included in the Proxy Statement or the Registration
      Statement) in connection with the transactions contemplated by this
      Agreement. 
  
           (b)  Each of the Company and the Acquiror will give prompt notice
      to the other of (i) any notice or other communication from any Person
      alleging that the consent of such Person is or may be required in
      connection with the Merger, (ii) any notice or other communication
      from any Governmental Authority in connection with the Merger,
      (iii) any actions, suits, claims, investigations or proceedings
      commenced or threatened in writing against, relating to or involving
      or otherwise affecting the Company, the Acquiror or their respective
      Subsidiaries that relate to the consummation of the Merger; (iv) the
      occurrence of a default or event that, with notice or lapse of time or
      both, will become a default under any Material Contract of the
      Acquiror or Material Contract of the Company; and (v) any change that
      is reasonably likely to have a Material Adverse Effect on the Company
      or the Acquiror or is likely to delay or impede the ability of either
      the Acquiror or the Company to consummate the transactions
      contemplated by this Agreement or to fulfill their respective
      obligations set forth herein. 
  
           (c)  The Acquiror Companies and the Company agree to cooperate
      and use all reasonable efforts vigorously to contest and resist any


      action, including legislative, administrative or judicial action, and
      to have vacated, lifted, reversed or overturned any Order (whether
      temporary, preliminary or permanent) of any Court of Governmental
      Authority that is in effect and that restricts, prevents or prohibits
      the consummation of the Merger or any other transactions contemplated
      by this Agreement.  Each of the Acquiror Companies and the Company
      also agree to take any and all actions, including the disposition of
      assets or the withdrawal from doing business in particular
      jurisdictions, required by any Court or Governmental Authority as a
      condition to the granting of any Permit or Order necessary for the
      consummation of the Merger or as may be required to avoid, lift,
      vacate or reverse any legislative or judicial action which would
      otherwise cause any condition to Closing not to be satisfied;
      provided, however, that in no event will either party be required to
      take, any action that would have an Material Adverse Effect on such
      party. 
  
           (d)  (i)  Each of the Company and Acquiror will give (or will
           cause their respective Subsidiaries to give) any notices to third
           Persons, and use, and cause their respective Subsidiaries to use,
           all reasonable efforts to obtain any consents from third Persons
           (A) necessary, proper or advisable to consummate the transactions
           contemplated by this Agreement, (B) otherwise required under any
           contracts, licenses, leases or other agreements in connection
           with the consummation of the transactions contemplated hereby or
           (C) required to prevent a Material Adverse Effect on the Company
           or the Acquiror from occurring prior to or after the Effective
           Time. 
  
                (ii) If any party shall fail to obtain any consent from a
           third Person described in Subsection 7.3(d)(i) above, such party
           will use all reasonable efforts, and will take any such actions
           reasonably requested by the other parties, to limit the adverse
           effect upon the Company and Acquiror, their respective
           Subsidiaries, and their respective businesses resulting, or which
           would result after the Effective Time, from the failure to obtain
           such consent. 
  
      Section 7.4    Affiliates; Pooling; Tax Treatment. 
  
           (a)  The Company will use all reasonable efforts to obtain an
      executed letter agreement substantially in the form of Annex C hereto
      from (i) each Person identified in Section 4.20 of the Company's
      Disclosure Letter within 15 days following the execution and delivery
      of this Agreement and (ii) from any Person who may be deemed to have
      become an Affiliate of the Company after the date of this Agreement
      and prior to the Effective Time as soon as practicable after attaining
      such status. 
  
           (b)  The Acquiror will use all reasonable efforts to obtain an
      executed letter agreement substantially in the form of Annex D hereto
      from (i) each Person identified in Section 5.12 of the Acquiror's
      Disclosure Letter within 15 days following the execution and delivery
      of this Agreement and (ii) from any Person who may be deemed to have
      become an Affiliate of the Acquiror after the date of this Agreement
      and prior to the Effective Time as soon as practicable after attaining
      such status. 
  
           (c)  The Acquiror Companies will not be required to maintain the
      effectiveness of the Registration Statement for the purpose of resale



      by stockholders of the Company who may be Affiliates of the Company
      pursuant to Rule 145 under the Securities Act. 
  
           (d)  Each party hereto will use all reasonable efforts to cause
      the Merger to be treated for financial accounting purposes as a
      "pooling of interests" and will not take, and will use all reasonable
      efforts to prevent any Affiliate of such party from taking, any
      actions which could prevent the Merger from being treated for
      financial accounting purposes as a "pooling of interests" under GAAP. 
  
           (e)  The parties hereto intend that the Merger will qualify as a
      reorganization within the meaning of Section 368(a) of the Code.  Each
      of the parties hereto shall, and shall cause its respective
      Subsidiaries to, and shall use its reasonable best efforts to cause
      the Merger to so qualify.   
  
      Section 7.5    Public Announcements.  The parties will consult with
 each other and will mutually agree upon any press release or public
 announcement pertaining to the Merger and shall not issue any such press
 release or make any such public announcement prior to such consultation and
 agreement, except as may be required by applicable law or by obligations
 pursuant to any listing agreement with any national securities exchange or
 national automated quotation system, in which case the party proposing to
 issue such press release or make such public announcement shall use
 reasonable efforts to consult in good faith with the other party before
 issuing any such press release or making any such public announcement. 
  
      Section 7.6    Stock Exchange Listing.  The Acquiror will use all
 reasonable efforts to cause the shares of Acquiror Common Stock (and the
 associated Acquiror Rights) to be issued in the Merger to be approved for
 listing (subject to official notice of issuance) on the NYSE prior to the
 Effective Time.  To the Knowledge of the Acquiror, there are no facts and
 circumstances that would preclude the Acquiror Common Stock (and the
 associated Acquiror Rights) to be issued in the Merger from being approved
 for listing on the NYSE. 
  
      Section 7.7    Employee Benefit Plans.   
  
           (a)  Except for obligations of the Company and its ERISA
      Affiliates that are in violation of the provisions of  Subsection
      6.2(a) hereof, the Acquiror hereby acknowledges and agrees to honor
      and to cause the Surviving Corporation and its Subsidiaries to honor
      and perform all obligations of the Surviving Corporation and its
      Subsidiaries  (including COBRA obligations) under all Employee Plans
      of the Company and its Subsidiaries, in accordance with their terms,
      including without limitation, the Indemnification Agreements set forth
      in Subsection 4.13 of the Company's Disclosure Letter. 
  
           (b)  The Acquiror will cause the Surviving Corporation to
      maintain through December 31, 1998 (the "Benefit Continuation
      Period"), the Employee Plans of the Company and its Subsidiaries set
      forth in Subsection 4.14(i) of the Company's Disclosure Letter,
      substantially as in effect immediately prior to the Effective Time. 
  
           (c)  From and after the Effective Time, including the Benefit
      Continuation Period, the Acquiror will grant to all individuals who
      are employed by the Company or its Subsidiaries on the Closing Date
      credit for all their service prior to the Effective Time with the
      Company and its Subsidiaries (and the respective predecessors of such
      entities) under all Employee Plans of the Acquiror and its
      Subsidiaries in which such employees will become eligible to


      participate, as if such service was service with the Acquiror or any
      Subsidiary thereof.  With respect to individuals who are employed by
      the Company or its Subsidiaries as of the Effective Time, Acquiror
      will waive all actively-at-work requirements and pre-existing
      condition limitations or exclusions under the Welfare Plans of the
      Acquiror and its Subsidiaries which provide medical, dental, or vision
      benefits or coverage (provided, however, that no such waiver will
      apply to a pre-existing condition of any employee of the Company or
      its Subsidiaries who was, as of the Effective Time, excluded from
      participation in a similar Welfare Plan of the Company or its
      Subsidiaries due to such pre-existing condition).  Furthermore, any
      covered expenses incurred on or before the Effective Time by an
      employee (or a covered dependent thereof) of the Company or its
      Subsidiaries under the Welfare Plans of the Company and its
      Subsidiaries which provide medical, dental, or vision benefits or
      coverage will be taken into account for purposes of satisfying any
      applicable deductible, coinsurance, and out-of-pocket maximum
      provisions under the Welfare Plans of the Acquiror and its
      Subsidiaries. 
  
      Section 7.8    Indemnification of Directors and Officers. 
  
           (a)  Until six (6) years from the Effective Time, the certificate
      of incorporation and bylaws of the Surviving Corporation as in effect
      immediately after the Effective Time will not be amended to reduce or
      limit the rights of indemnity afforded to the present and former
      directors and officers of the Company thereunder, to reduce or limit
      the ability of the Company to indemnify such Persons, or to hinder,
      delay or make more difficult the exercise of such rights of indemnity
      or the ability to indemnify.  The Surviving Corporation will at all
      times exercise the powers granted to it by its certificate of
      incorporation, its bylaws and applicable Law to indemnify to the
      fullest extent possible the present and former directors, officers,
      employees and agents of the Company against claims made against them
      arising from their service in such capacities prior to the Effective
      Time. 
  
           (b)  If any claim or claims shall, subsequent to the Effective
      Time and within six (6) years thereafter, be made against any present
      or former director, officer, employee or agent of the Company based on
      or arising out of the services of such Person prior to the Effective
      Time in the capacity of such Person as a director, officer, employee
      or agent of the Company, the provisions of Subsection 7.8(a) hereof
      respecting the certificate of incorporation and bylaws of the
      Surviving Corporation will continue in effect until the final
      disposition of all such claims. 
  
           (c)  The Acquiror hereby agrees after the Effective Time to
      guarantee the payment of the Surviving Corporation's indemnification
      obligations described in Subsection 7.8(a) hereof.  
  
           (d)  Notwithstanding subsection (a), (b) or (c) of this
      Section 7.8, the Acquiror and the Surviving Corporation will be
      released from the obligations imposed by such subsection if the
      Acquiror will assume the obligations of the Surviving Corporation
      thereunder by operation of Law or otherwise.  Notwithstanding anything
      to the contrary in this Section 7.8, neither the Acquiror nor the
      Surviving Corporation will be liable for any settlement effected
      without its written consent, which will not be unreasonably withheld
      or delayed. 

           (e)  The Acquiror will cause to be maintained in effect until six
      (6) years from the Effective Time the current policies of directors'
      and officers' liability insurance maintained by the Company (or
      substitute policies providing at least the same coverage and limits
      and containing terms and conditions that are not materially less
      advantageous) with respect to claims arising from facts or events
      which occurred before the Effective Time; provided, however, that in
      no event will the Acquiror or the Surviving Corporation be required to
      expend more than two hundred percent (200%) of the current annual
      premiums paid by the Company for such insurance; provided, further,
      that, if the Acquiror or the Surviving Corporation is unable to obtain
      insurance for any period for two hundred percent (200%) of the current
      annual premiums, then the obligation of the Acquiror and the Surviving
      Corporation pursuant hereto will be to obtain the best coverage
      reasonably available under the circumstances subject to the foregoing
      limitations on premiums. 
  
           (f)  The provisions of this Section 7.8 are intended to be for
      the benefit of, and will be enforceable by, each Person entitled to
      indemnification hereunder and the heirs and representatives of such
      Person. 
  
           (g)  The Acquiror will not, and will not permit the Surviving
      Corporation to, merge or consolidate with any other Person unless the
      Surviving Corporation will ensure that the surviving or resulting
      entity assumes the obligations imposed by subsections (a), (b), (c)
      and (e) of this Section 7.8. 
  
      Section 7.9    Newco.  Prior to the Effective Time, Newco will not
 conduct any business or make any investments other than as specifically
 contemplated by this Agreement and will not have any assets (other than the
 minimum amount of cash required to be paid to Newco for the valid issuance
 of its stock to the Acquiror).  The Acquiror will take all action necessary
 to cause Newco to perform its obligations under this Agreement and to
 consummate the Merger on the terms and conditions set forth in this
 Agreement. 
  
      Section 7.10   Event Notices.  From and after the date of this
 Agreement until the Effective Time, each party hereto will promptly notify
 the other party hereto of (i) the occurrence or nonoccurrence of any event
 the occurrence or nonoccurrence of which would be likely to cause any
 condition to the obligations of such party to effect the Merger and the
 other transactions contemplated by this Agreement not to be satisfied and
 (ii) the failure of such party to comply with any covenant or  agreement to
 be complied with by it pursuant to this Agreement which would be likely to
 result in any condition to the obligations of such party to effect the
 Merger and the other transactions contemplated by this Agreement not to be
 satisfied.  No delivery of any notice pursuant to this Section 7.10 will
 cure any breach of any representation or warranty of such party contained
 in this Agreement or otherwise limit or affect the remedies available
 hereunder to the party receiving such notice. 
  
      Section 7.11   Assumption of Obligations to Issue Stock. 
  
           (a)  At the Effective Time, automatically and without any action
      on the part of the holder thereof, each outstanding Company Stock
      Option shall become an option to purchase that number of shares of
      Acquiror Common Stock (and associated Acquiror Rights) obtained by
      multiplying the number of shares of Company Common Stock issuable upon
      the exercise of such option by the Exchange Ratio at an exercise price
      per share equal to the per share exercise price of such option divided


      by the Exchange Ratio and otherwise upon the same terms and conditions
      as such outstanding options to purchase Company Common Stock;
      provided, however, that in the case of any option to which Section 421
      of the Code applies by reason of the qualifications under Section 422
      or 423 of the Code, the exercise price, the number of shares
      purchasable pursuant to such option and the terms and conditions of
      exercise of such option shall be determined in a manner that complies
      with Section 424(a) of the Code. 
  
           (b)  On or prior to the Effective Time, the Company shall take or
      cause to be taken all such actions, reasonably satisfactory to the
      Acquiror, as may be necessary or desirable in order to authorize the
      transactions contemplated by Subsection 7.11(a) hereof.  Except as
      provided in this Agreement or pursuant to the provisions of any
      Company Option Plans or employee or director stock option agreement as
      in effect on the date hereof, from the date hereof the Company will
      not accelerate the vesting or exercisability of or otherwise modify
      the terms and conditions applicable to the Company Stock Options. 
  
           (c)  The Acquiror shall take all corporate actions necessary to
      reserve for issuance a sufficient number of shares of Acquiror Common
      Stock (and associated Acquiror Rights) for delivery upon exercise of
      the Company Stock Options. 
  
           (d)  As promptly as practicable after the Effective Time, the
      Acquiror shall file one or more Registration Statements on Form S-8
      (or any successor or other appropriate forms) with respect to the
      shares of Acquiror Common Stock (and associated Acquiror Rights)
      subject to the Company Stock Options and shall use its reasonable
      efforts to maintain the effectiveness of such registration statement
      or registration statements (and maintain the current status of the
      prospectus or prospectuses contained therein) for so long as such
      options remain outstanding and to comply with applicable state
      securities and blue sky laws. 
  
      Section 7.12   Real Estate Transfer Tax Returns.  The Company shall
 cooperate with the Acquiror and Newco in the preparation and filing of any
 Tax Return required to be filed with any tax authority with respect to any
 transfer or deemed transfer of the beneficial ownership of the Company's
 real property, including supplying in a timely manner a complete list of
 all real property interests held by the Company and any information with
 respect to such property that is reasonably necessary to complete any such
 Tax Return.  The fair market value of any such real property shall be
 determined by the Acquiror. 
  
      Section 7.13   Acquiror's Board of Directors and Officers.  Acquiror
 shall take all steps necessary to cause (i) the size of the Acquiror's
 Board of Directors to be expanded to a number no larger than eight and (ii)
 the appointment as of the Effective Time of L.J. Sevin, Dietrich Erdmann
 and Alan R. Schuele to the Board of Directors of Acquiror, or any
 substitute for such persons as shall be selected prior to the Effective
 Time by the Company's Board of Directors and as shall be reasonably
 acceptable to Acquiror, Acquiror shall use its best efforts to cause
 Messrs. Sevin, Erdmann and Schuele to be nominated to the Acquiror's Board
 of Directors at the Acquiror's next annual meeting and solicit, in good
 faith and with reasonable diligence, proxies in support of such nomination. 
 At such annual meeting Mr. Sevin shall be nominated to term of office
 expiring  at the annual meeting of the Acquiror's stockholders to be held
 in 1999.  Mr. Erdmann shall be nominated to term of office expiring at the
 annual meeting of the Acquiror's stockholders to be held in 2000 and Mr.
 Schuele shall be nominated to term of office expiring at the annual meeting


 of the Acquiror's stockholders to be held in 2001.  Acquiror shall take all
 steps necessary to cause the appointment as of the Effective Time of Mr.
 Schuele to the office of President and Chief Operating Officer of Acquiror. 


  
                                ARTICLE VIII 
  
                             CLOSING CONDITIONS 
  
      Section 8.1    Conditions to Obligations of Each Party Under This
 Agreement.  The respective obligations of each party to effect the Merger
 and the other transactions contemplated hereby will be subject to the
 satisfaction at or prior to the Effective Time of the following conditions,
 any or all of which may be waived by the party entitled to the benefit
 thereof, in whole or in part, to the extent permitted by applicable Law: 
  
           (a)  Effectiveness of the Registration Statement.  The
      Registration Statement shall have become effective in accordance with
      the provisions of the Securities Act and no stop order suspending the
      effectiveness of the Registration Statement shall be pending before or
      threatened and no proceedings for that purpose shall be in effect by
      the Commission. 
  
           (b)  Stockholder Approval.  This Agreement and the Merger shall
      have been approved and adopted by the requisite vote of the
      stockholders of the Company in accordance with the DGCL and the
      certificate of incorporation and by-laws of the Company.  The issuance
      of shares of Acquiror Common Stock pursuant to this Agreement shall
      have been approved by the requisite vote of the stockholders of the
      Acquiror in accordance with the requirements of the NYSE and the
      articles of incorporation and bylaws of the Acquiror. 
  
           (c)  No Order.  No Court or Governmental Authority having
      jurisdiction over the Company or the Acquiror shall have enacted,
      issued, promulgated, enforced or entered any Law, Regulation or Order
      (whether temporary, preliminary or permanent) which is then in effect
      and which has the effect of making the Merger illegal or otherwise
      prohibiting consummation of the Merger. 
  
           (d)  Regulatory Approvals.  All approvals and consents of
      applicable Courts or Governmental Authorities required to consummate
      the Merger which the failure to obtain would have a Material Adverse
      Effect on the Acquiror or the Surviving Corporation shall have been
      received and all applicable waiting periods shall have expired or been
      terminated.   

           (e)  Stock Exchange Listing.  The shares of Acquiror Common Stock
      (and the associated Acquiror Rights) to be issued pursuant to the
      Merger shall have been approved for listing, subject to official
      notice of issuance, on the NYSE. 
  
           (f)  Pooling of Interests.  The Acquiror shall have been advised
      in writing by Coopers & Lybrand L.L.P. as of the date upon which the
      Effective Time is to occur that such firm concurs with the management
      of Acquiror that there is no reason why the Merger cannot be treated
      for financial accounting purposes as a "pooling of interests" under
      GAAP.  The Company shall have been advised in writing by Ernst & Young
      L.L.P. as of the date upon which the Effective Time is to occur that
      such firm concurs with the management of the Company that there is no
      reason why the Merger cannot be treated for financial accounting
      purposes as a "pooling of interests" under GAAP. 

      Section 8.2    Additional Conditions to Obligations of the Acquiror
 Companies.  The obligations of the Acquiror Companies to effect the Merger
 and the other transactions contemplated hereby shall be subject to the
 satisfaction at or prior to the Effective Time of the following additional
 conditions, any or all of which may be waived by the Acquiror Companies, in
 whole or in part, to the extent permitted by applicable Law: 
  
           (a)  Representations and Warranties.  Each of the representations
      and warranties of the Company contained in this Agreement to the
      extent it is qualified as to Material Adverse Effect shall be true and
      correct and each such representation and warranty to the extent that
      it is not so qualified shall be true and correct (without regard to
      any other materiality qualification) such that the aggregate effect of
      any inaccuracies in such representations and warranties will not have
      a Material Adverse Effect on the Company, in each case as of the date
      hereof and at and as of the Effective Time as if made at and as of
      such time, except that those representations and warranties which
      address matters only as of a particular date shall remain true and
      correct as of such date.  The Acquiror Companies shall have received a
      certificate of the President and the Chief Financial Officer of the
      Company, dated the date of the Effective Time, to such effect. 
  
           (b)  Agreements and Covenants.  The Company shall have performed
      or complied in all respects with all agreements and covenants required
      by this Agreement to be performed or complied with by it on or prior
      to the Effective Time.  The Acquiror Companies shall have received a
      certificate of the President and the Chief Financial Officer of the
      Company, dated the date of the Effective Time, to such effect.

      of its tax counsel, Skadden, Arps, Slate, Meagher & Flom LLP, to the
      effect that the Merger will qualify as a reorganization within the
      meaning of Section 368(a) of the Code.  The issuance of such opinion
      shall be conditioned on the receipt by such tax counsel of
      representation letters from each of the Acquiror, Newco and the
      Company, in each case, in form and substance reasonably satisfactory
      to Skadden, Arps, Slate, Meagher & Flom LLP.  The specific provisions
      of each such representation letter shall be in form and substance
      reasonably satisfactory to such tax counsel, and each such
      representation letter shall be dated on or before the date of such
      opinion and shall not have been withdrawn or modified in any material
      respect. 
  
      Section 8.3    Additional Conditions to Obligations of the Company. 
 The obligations of the Company to effect the Merger and the other
 transactions contemplated hereby shall be subject to the satisfaction at or
 prior to the Effective Time of the following additional conditions, any or
 all of which may be waived by the Company, in whole or in part, to the
 extent permitted by applicable Law: 
  
           (a)  Representations and Warranties.  Each of the representations
      and warranties of the Acquiror Companies contained in this Agreement
      to the extent it is qualified as to Material Adverse Effect shall be
      true and correct and each such representation and warranty to the
      extent that it is not so qualified shall be true and correct (without
      regard to any other materiality qualification) such that the aggregate
      effect of any inaccuracies in such representations and warranties will
      not have a Material Adverse Effect on the Acquiror Companies, in each
      case as of the date hereof and at and as of the Effective Time as if
      made at and as of such time, except that those representations and
      warranties which address matters only as of a particular date shall


      remain true and correct as of such date.  The Company shall have
      received a certificate of the President and the Chief Financial
      Officer of each of the Acquiror Companies, dated the date of the
      Effective Time, to such effect. 
  
           (b)  Agreements and Covenants.  The Acquiror Companies shall have
      performed or complied in all respects with all agreements and
      covenants required by this Agreement to be performed or complied with
      by them on or prior to the Effective Time.  The Company shall have
      received a certificate of the President and the Chief Financial
      Officer of each of the Acquiror Companies, dated the date of the
      Effective Time, to such effect. 
  
           (c)  Tax Opinion.  The Company shall have received the opinion of
      its tax counsel, Winstead Sechrest & Minick P.C., to the effect that
      the Merger will qualify as a reorganization within the meaning of
      Section 368(a) of the Code.  The issuance of such opinion shall be
      conditioned on the receipt by such tax counsel of representation
      letters from each of the Acquiror, Newco and the Company, in each
      case, in form and substance reasonably satisfactory to Winstead
      Sechrest & Minick P.C.  The specific provisions of each such
      representation letter shall be in form and substance reasonably
      satisfactory to such tax counsel, and each such representation letter
      shall be dated on or before the date of such opinion and shall not
      have been withdrawn or modified in any material respect.

                     TERMINATION, AMENDMENT AND WAIVER 
  
      Section 9.1    Termination.  This Agreement may be terminated at any
 time prior to the Effective Time, whether before or after approval of this
 Agreement and the Merger by the stockholders of the Company: 
  
           (a)  by mutual consent of the Acquiror and the Company; 
  
           (b)  by the Acquiror, upon a breach of any covenant or agreement
      on the part of the Company set forth in this Agreement, or if any
      representation or warranty of the Company shall have become untrue, in
      either case such that the conditions set forth in Subsection 8.2(a) or
      Subsection 8.2(b) would not be satisfied (a "Terminating Company
      Breach"); provided that, if such Terminating Company Breach is curable
      by the Company through the exercise of reasonable efforts, provided
      the Company continues to exercise such reasonable efforts, the
      Acquiror may not terminate this Agreement under this Subsection 9.1(b)
      unless such Terminating Company Breach is not cured within 20 days
      after written notice of such breach is given by the Acquiror to the
      Company; 
  
           (c)  by the Company, upon breach of any covenant or agreement on
      the part of the Acquiror Companies set forth in this Agreement, or if
      any representation or warranty of the Acquiror Companies shall have
      become untrue, in either case such that the conditions set forth in
      Subsection 8.3(a) or Subsection 8.3(b) would not be satisfied (a
      "Terminating Acquiror Breach"); provided that, if such Terminating
      Acquiror Breach is curable by the Acquiror Companies through the
      exercise of their reasonable efforts, provided the Acquiror Companies
      continue to exercise such reasonable efforts, the Company may not
      terminate this Agreement under this Subsection 9.1(c) unless such
      Terminating Acquiror Breach is not cured within 20 days after written
      notice of such breach is given by the Company to the Acquiror; 


  
           (d)  by either Acquiror or the Company, if there shall be any
      Order which is final and nonappealable permanently enjoining,
      restraining or prohibiting the consummation of the Merger, unless the
      party relying on such Order has not complied with its obligations
      under Section 7.3 hereof;  
  
           (e)  by either Acquiror or the Company, if the Merger shall not
      have been consummated before October 31, 1998; unless the party
      seeking to terminate this Agreement has not complied with its
      obligations under Section 7.3 hereof,  provided, however, that the
      right to terminate this Agreement under this Subsection 9.1(e) shall
      not be available to any party whose failure to fulfill any obligation
      under this Agreement has been the cause of, or resulted in, the
      failure of the Effective Time to occur on or before the Termination
      Date; 
  
           (f)  by either Acquiror or the Company, if this Agreement shall
      fail to receive the requisite vote for approval and adoption by the
      stockholders of the Company at the Company Stockholders' Meeting; 
  
           (g)  by either Acquiror or the Company if the issuance of
      Acquiror Common Stock pursuant to this Agreement shall fail to receive
      the requisite vote for approval by the stockholders of Acquiror at the
      Acquiror's Stockholders' Meeting; 
  
           (h)  by the Company, if the Pre-Closing Average Price is less
      than $12.00 per share; 
  
           (i)  by the Acquiror, if the Board of Directors of the Company
      (i) fails to recommend approval and adoption of this Agreement and the
      Merger by the stockholders of the Company or withdraws or modifies (or
      publicly announces an intention to withdraw or modify) in any adverse
      manner its approval or recommendation of this Agreement or the Merger;
      (ii) makes any recommendation with respect to any Acquisition Proposal
      other than a recommendation to reject such Acquisition Proposal; (iii)
      takes any action prohibited by Section 6.3, or which would be
      prohibited by Section 6.3 but for the second sentence thereof; (iv)
      enters into any agreement relating to an Acquisition Proposal other
      than this Agreement or the Option Agreement; or (v) resolves to do any
      of the foregoing; and 
  
           (j)  by the Company, if the Board of Directors of the Acquiror
      fails to recommend approval of the issuance of shares of Acquiror
      Common Stock pursuant to this Agreement by the stockholders of the
      Acquiror or withdraws or modifies (or publicly announces an intention
      to withdraw or modify) its approval and recommendation in a manner
      materially adverse to the Company or shall have resolved to do any of
      the foregoing;  
  
      The right of any party hereto to terminate this Agreement pursuant to
 this Section 9.1 hereof will remain operative and in full force and effect
 regardless of any investigation made by or on behalf of any party hereto,
 any Person controlling any such party or any of their respective officers,
 directors, representatives or agents, whether prior to or after the
 execution of this Agreement. 
  






      Section 9.2    Effect of Termination.   
  
           (a)  In the event of the termination of this Agreement pursuant
      to Section 9.1, this Agreement will forthwith become void, and there
      will be no liability on the part of the Acquiror Companies or the
      Company or any of their respective officers or directors to the other
      and all rights and obligations of any party hereto will cease, except
      (i) as set forth in this Section 9.2 and in Section 10.1 hereof and
      (ii)  nothing herein will relieve any party from liability for any
      breach of this Agreement. 
  
           (b)  If this Agreement is terminated (i) by the Acquiror pursuant
      to clause (i) of Subsection 9.1(i) hereof (except under circumstances
      which would permit the Company to terminate this Agreement under
      Subsection 9.1(h)); (ii) by the Acquiror pursuant to Subsection 9.1(i)
      hereof under any circumstances other than those described in clause
      (i) of this Subsection 9.2(b); (iii) by Acquiror or Company pursuant
      to Subsection 9.1(f) hereof because of the failure to obtain the
      required approval from the Company stockholders and at the time of
      such termination or prior to the Company Stockholders' Meeting there
      shall have been an Acquisition Proposal (whether or not such offer,
      proposal, announcement or agreement shall have been rejected or shall
      have been withdrawn prior to the time of such termination or of the
      Company Stockholders' Meeting); or (iv) by Acquiror as a result of
      Company's material breach of Section 7.3 or Subsection 7.1(a) hereof,
      the Company shall promptly pay to Acquiror or the Company by wire
      transfer of same day funds not later than two Business Days after the
      date of such termination a termination fee of $4,528,000 (the
      "Termination Fee") provided, however, that if this Agreement is
      terminated by Acquiror or the Company pursuant to Subsection 9.1(f)
      hereof under the circumstances described in Subsection 9.2(b)(ii)
      hereof, and at the time of such termination the stockholders of the
      Acquiror shall have failed to approve the issuance of Acquiror Common
      Stock pursuant to this Agreement, the Acquiror shall not be entitled
      to the Termination Fee. 
  
           (c)  If  this Agreement is terminated by the Company pursuant to
      Subsection 9.1(i) hereof, and at the time of such termination there
      shall have been an Acquiror Acquisition Proposal (whether or not such
      offer, proposal, announcement or agreement shall have been rejected or
      shall have been withdrawn prior to the time of such termination), and
      the stockholders of Acquiror shall have failed to approve the issuance
      of Acquiror Common Stock pursuant this Agreement, the Acquiror shall
      promptly pay to the Company by wire transfer of same day funds not
      later than two Business Days after the date of such termination a
      termination fee of $2,000,000. 
  
      Section 9.3    Amendment.  Subject to the requirements of Law, this
 Agreement may be amended by the parties hereto by action taken by or on
 behalf of their respective Boards of Directors at any time prior to the
 Effective Time; provided, however, that, after approval of the Merger by
 the stockholders of the Company, no amendment may be made which would
 reduce the amount or change the type of consideration into which each share
 of Company Common Stock will be converted pursuant to this Agreement upon
 consummation of the Merger.  This Agreement may not be amended except by an
 instrument in writing signed by the parties hereto. 
  
      Section 9.4    Waiver.  At any time prior to the Effective Time, any
 party hereto may (a) extend the time for the performance of any of the
 obligations or other acts of the other party hereto, (b) waive any
 inaccuracies in the representations and warranties of the other party


 contained herein or in any document delivered pursuant hereto and (c) waive
 compliance by the other party with any of the agreements or conditions
 contained herein.  Any such extension or waiver will be valid only if set
 forth in an instrument in writing signed by the party or parties to be
 bound thereby.  For purposes of this Section 9.4, the Acquiror Companies
 will be deemed to be one party. 
  
      Section 9.5    Expenses.  All Expenses incurred by the parties hereto
 will be borne solely and entirely by the party which has incurred such
 Expenses; provided, however, that the allocable share of the Acquiror
 Companies as a group and the Company for all Expenses related to printing,
 filing and mailing the Registration Statement and the Proxy Statement and
 all Commission and other regulatory filing fees incurred in connection with
 the Registration Statement and  the Proxy Statement will be one-half each;
 and provided, further, that the Acquiror may, at its option, pay any
 Expenses of the Company that are solely and directly related to the Merger.

      Section 10.8   Failure or Indulgence Not Waiver;  Remedies Cumulative. 
 No failure or delay on the part of any party hereto in the exercise of any
 right hereunder will impair such right or be construed to be a waiver of,

Grantee's entering into the Merger Agreement and in consideration
therefor, the Company has agreed to grant Grantee the Option (as
hereinafter defined);

            NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements contained herein and in the Merger
Agreement, and intending to be legally bound hereby, the parties hereby
agree as follows:


            1. GRANT OF OPTION. The Company hereby grants to Grantee an
unconditional, irrevocable option (the "Option") to purchase, subject to
the terms hereof, 955,158 shares (such shares being referred to herein as
the "Option Shares") of fully paid and nonassessable common stock, par
value $.001 per share, of the Company ("Company Common Stock"), equal to
approximately ten percent (10%) of the number of shares of Company Common
Stock issued and outstanding (on a fully diluted basis after giving
effect to the exercise of the Option) as of the date hereof at a purchase
price of $17.53 per share of Company Common Stock, as adjusted in
accordance with the provisions of Section 8 (such price, as adjusted if
applicable, the "Option Price").

            2. (a) EXERCISE OF OPTION. Grantee may exercise the Option,
in whole or part, and from time to time, if, but only if, a Triggering
Event (as hereinafter defined) shall have occurred prior to the
occurrence of an Option Termination Event (as hereinafter defined),
provided that Grantee shall have sent the written notice of such exercise
(as provided in Subsection 2(e) on or prior to the last date of the one
(1) year period following such Triggering Event (the "Option Expiration
Date").

            (b) OPTION TERMINATION EVENTS. The term "Option Termination
Event" shall mean any of the following events:

                  (i)  the Effective Time (as defined in the Merger
      Agreement); or

                  (ii) termination of the Merger Agreement (A) by either
      party pursuant to Subsection 9.1(d) of the Merger Agreement,
      provided that the matter giving rise to the Order (as defined in
      the Merger Agreement) providing the basis for termination under
      Subsection 9.1(d) of the Merger Agreement shall not have been
      initiated by the Company or any Person who initiates an Acquisition
      Proposal (as such item is defined in the Merger Agreement), (B) by
      the Company pursuant to Subsection 9.1(c), Subsection 9.1(h) or
      Subsection 9.1(j) of the Merger Agreement, (C) by either the
      Company or the Grantee pursuant to Subsection 9.1(g) of the Merger
      Agreement, (D) by both parties pursuant to Subsection 9.1(a) of the
      Merger Agreement, (E) by the Company or the Grantee pursuant to
      Subsection 9.1(e) of the Merger Agreement (if there then exists
      circumstances that would permit termination of the Merger Agreement
      by the Company pursuant to Subsection 9.1(e) of the Merger
      Agreement), (F) by the Acquiror pursuant to Subsection 9.1(i)(i)
      (if circumstances exist that would allow the Company to terminate
      the Merger Agreement pursuant to Subsection 9.1(h) of the Merger
      Agreement) or (G) by either party pursuant to any other provision
      of the Merger Agreement; provided (in the case of this Subsection
      2(b)(ii)(G)) such termination occurs prior to the occurrence of an
      Acquisition Proposal.

            (c) TRIGGERING EVENTS. The term "Triggering Event" shall mean
the occurrence (after the date hereof) of any of the following events:

                  (i) any Person (other than the Grantee or any
      Subsidiary of the Grantee) shall have commenced (as such term is
      defined in Rule 14d-2 under the Exchange Act) or shall have filed a
      registration statement under the Securities Act with respect to a
      tender offer or exchange offer to purchase any shares of Company
      Common Stock such that, upon consummation of such offer, such
      Person would own or control 10% or more of the then outstanding
      Company Common Stock;

                  (ii) the Company or any Subsidiary of the Company shall
      have authorized, recommended, proposed or publicly announced an
      intention to authorize, recommend or propose, or entered into, an
      agreement with any Person (other than the Grantee or any Subsidiary
      of the Grantee) to (A) effect a merger, reorganization,
      consolidation, share exchange or other business combination or
      similar transaction involving the Company or any of its Significant
      Subsidiaries, (B) sell, lease or otherwise dispose of assets of the
      Company or its Subsidiaries representing 10% or more of the
      consolidated assets of the Company other than in the ordinary
      course of business or (C) issue, sell or otherwise dispose of
      (including by way of merger, reorganization, consolidation, share
      exchange or other business combination or any similar transaction)
      securities (or options, rights or warrants to purchase, or
      securities convertible into or exchangeable for, such securities)
      representing 10% or more of the voting power of the Company or any
      of its Significant Subsidiaries; or

                  (iii) any Person (other than the Grantee or any
      Subsidiary of the Grantee or the Company or, in a fiduciary
      capacity, any Subsidiary of the Company) shall have,
      subsequent to the date of this Agreement, acquired beneficial
      ownership (as such term is defined in Rule 13d-3 under the Exchange
      Act) or the right to acquire beneficial ownership of, or any
      "Group" (as such term is defined under the Exchange Act) shall have
      been formed which beneficially owns or has the right to acquire
      beneficial ownership of, 10% or more of the then outstanding
      Company Common Stock.

            (d) NOTICE OF TRIGGERING EVENT. The Company shall notify
Grantee in writing as promptly as practicable, and in any event within 24
hours, of the occurrence of any Triggering Event, it being understood
that the giving of such notice by the Company shall not be a condition to
the right of Grantee to exercise the Option or for a Triggering Event to
have occurred.

            (e) NOTICE OF EXERCISE; CLOSING. In the event that Grantee is
entitled to and wishes to exercise the Option, it shall send to the
Company a written notice (such notice being herein referred to as an
"Exercise Notice" and the date of issuance of an Exercise Notice being
herein referred to as the "Notice Date") specifying (i) the total number
of shares (or other Option Securities (as hereinafter defined)) it will
purchase pursuant to such exercise and (ii) a place and date not earlier
than three (3) Business Days nor later than forty (40) Business Days from
the Notice Date for the closing of such purchase (the "Option Closing
Date"); provided, that if the closing of the purchase and sale pursuant
to the Option (the "Option Closing") cannot be consummated, by reason of
any applicable Order, the period of time that otherwise would run
pursuant to this sentence shall run instead from the date on which such
restriction on consummation has expired or been terminated; and provided
further, without limiting the foregoing, that if, in the reasonable
opinion of Grantee, prior notification to or approval of any regulatory
agency is required in connection with such purchase, the Company or
Grantee, as the case may be, shall promptly file the required notice or
application for approval and shall expeditiously process the same and the
period of time that otherwise would run pursuant to this sentence shall
run instead from the date on which any required notification periods have
expired or been terminated or such approvals have been obtained and any
requisite waiting period or periods shall have passed. In the event that
(x) Grantee receives official notice that an approval of any regulatory
authority required for the purchase of Option Shares (or other Option
Securities) would not be issued or granted or (y) an Option Closing Date
shall not have occurred within one (1) year after the related Notice Date
due to the failure to obtain any such required approval, Grantee shall,
to the extent permitted by applicable Law, nevertheless be entitled to
exercise its rights as set forth herein, including without limitation the
rights set forth in Subsection 8(a) and Grantee shall be entitled to
exercise the Option (or Substitute Option (as defined herein)) in
connection with the resale of the Company Common Stock or other Option
Securities pursuant to a registration statement as provided in Section 9.

            (f) PURCHASE PRICE. At the Option Closing, Grantee shall pay
to the Company the aggregate Option Price in immediately available funds
by wire transfer to a bank account designated by the Company, provided
that failure or refusal of the Company to designate such a bank account
shall not preclude Grantee from exercising the Option.

            (g) ISSUANCE OF COMPANY COMMON STOCK. At the Option Closing,
simultaneously with the delivery of immediately available funds as
provided in Subsection 2(f), the Company shall deliver to Grantee a
certificate or certificates representing the number of shares of Company
Common Stock (or other Option Securities) purchased by Grantee and, if
the Option should be exercised in part only, a new Option evidencing the
rights of Grantee thereof to purchase the balance of the shares (or other
Option Securities) purchasable hereunder. If at the time of issuance of
any Option Shares pursuant to an exercise of all or part of the Option
hereunder, the Company shall have issued any rights or other securities
which are attached to or otherwise associated with the Company Common
Stock, then each Option Share issued pursuant to such exercise shall also
represent such rights or other securities with terms substantially the
same as and at least as favorable to Grantee as are provided under any
shareholder rights agreement or similar agreement of the Company then in
effect.

            (h) LEGEND. Certificates for Company Common Stock (or other
Option Securities) delivered at a closing hereunder may be endorsed with
a restrictive legend that shall read substantially as follows:

      "The transfer of the shares represented by this certificate is
subject to resale restrictions arising under the Securities Act of 1933,
as amended."

It is understood and agreed that the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "Securities Act"), in the
above legend shall be removed by delivery of substitute certificate(s)
without such reference if Grantee shall have delivered to the Company a
copy of a letter from the staff of the SEC, or an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such legend is
not required for purposes of the Securities Act. In addition, such
certificates shall bear any other legend as may be required by Law.

            (i) RECORD GRANTEE; EXPENSES. Upon the delivery by Grantee to
the Company of the Exercise Notice and the tender of the applicable
Option Price in immediately available funds, Grantee shall be deemed to
be the holder of record of the shares of Company Common Stock (or other
Option Securities) issuable upon such exercise, notwithstanding that the
stock transfer books of the Company shall then be closed or that
certificates representing such shares of Company Common Stock (or other
Option Securities) shall not then be actually delivered to Grantee or the
Company shall have failed or refused to designate the bank account
described in Subsection 2(f). The Company shall pay all expenses, and any
and all United States federal, state and local taxes and other charges
that may be payable in connection with the preparation, issuance and
delivery of stock certificates under this Section 2 in the name of
Grantee. The Grantee shall pay all expenses and any and all United States
federal, state, local or other taxes or charges that may be payable in
connection with the issuance and delivery of stock certificates or a
substitute option agreement in the name of any assignee, transferee or
designee of Grantee.

            3. EVALUATION OF INVESTMENTS. Grantee, by reason of its
knowledge and experience in financial and business matters, believes
itself capable of evaluating the merits and risks of an investment in the
Option and the securities to be purchased/sold pursuant to this Agreement
(collectively the "Option Securities.")

            4. DOCUMENTS DELIVERED. Grantee acknowledges receipt of
copies of the following documents:

            (a)   The Company's Annual Report on Form 10-K for the year ended
                  December 31, 1996;

            (b)   The Company's Proxy Statement for the meeting of the
                  Company's stockholder held April 16, 1997; and

            (c)   The Company's Quarterly Report on Form 10-Q for the quarter
                  ended September 30, 1997.

            5. INVESTMENT INTENT. Grantee represents and warrants that
it is entering into this Agreement and is acquiring and/or will acquire
the Option Securities for its own account and not with a view to resale
or distribution of all or any part of the Option Securities in violation
of applicable Law.

            6. RESERVATION OF SHARES. The Company agrees (i) that it
shall at all times maintain, free from preemptive rights, sufficient
authorized but unissued or treasury shares of Company Common Stock (and
other Option Securities) issuable pursuant to this Agreement so that the
Option may be exercised without additional authorization of Company
Common Stock (or such other Option Securities) after giving effect to all
other options, warrants, convertible securities and other rights to
purchase Company Common Stock (or such other Option Securities); (ii)
that it will not, by charter amendment or through reorganization,
consolidation, merger, dissolution or sale of assets, or by any other
voluntary act, avoid or seek to avoid the observance or performance of
any of the covenants, stipulations or conditions to be observed or
performed hereunder by the Company; (iii) promptly to take all action as
may from time to time be required in order to permit Grantee to exercise
the Option and the Company to duly and effectively issue shares of
Company Common Stock (or other Option Securities) pursuant hereto; and
(iv) (to the extent agreed to herein) promptly to take all action
provided herein to protect the rights of Grantee against dilution.

            7. DIVISION OF OPTION; LOST OPTIONS. This Agreement (and the
Option granted hereby) are exchangeable, without expense, at the option
of Grantee, upon presentation and surrender of this Agreement at the
principal office of the Company, for other Agreements providing for
Options of different denominations entitling the holder thereof to
purchase, on the same terms and subject to the same conditions as are set
forth herein, in the aggregate the same number of shares of Company
Common Stock purchasable hereunder. The terms "Agreement" and "Option" as
used herein include any Stock Option Agreements and related Options for
which this Agreement (and the Option granted hereby) may be exchanged.
Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Agreement, and (in the
case of loss, theft or destruction) of reasonably satisfactory
indemnification, and upon surrender and cancellation of this Agreement,
if mutilated, the Company will execute and deliver a new Agreement of
like tenor and date.

            8. ADJUSTMENT UPON CHANGES IN CAPITALIZATION. The number of
shares of Company Common Stock purchasable upon the exercise of the
Option shall be subject to adjustment from time to time as provided in
this Section 8.

            (a) ADDITIONAL SHARES ADJUSTMENT. Excluding issuances
contemplated by Subsection 8(b), in the event that any additional shares
of Company Common Stock, or any rights, options, warrants, subscriptions,
calls, convertible securities or other agreements or commitments
obligating the Company to issue any shares of Company Common Stock, are
issued or otherwise become outstanding after the date hereof (an
"Increase"), the number of shares of Company Common Stock subject to the
Option shall be increased by a number of shares equal to the product of
(A) a fraction, the numerator of which is the number of shares of Company
Common Stock for which the Option was exercisable immediately prior to
the Increase and the denominator of which is the number of shares of
Company Common Stock specified in Section 1 and (B) the product of (i)
ten percent (10%) and (ii) the number of shares of Company Common Stock
issued and outstanding on a fully diluted basis immediately after the
Increase minus the number of shares of Company Common Stock issued and
outstanding on a fully diluted basis immediately prior to the Increase;
provided that the number of shares of Company Common Stock subject to the
Option shall in no event exceed ten percent (10%) of the issued and
outstanding shares of Company Common Stock on a fully diluted basis
immediately prior to exercise.

            (b) TRANSACTION ADJUSTMENT. In the event of any change in
Company Common Stock by reason of stock dividends, splits, mergers,
recapitalization, combinations, subdivisions, conversions, exchanges of
shares or other similar transactions then, the type and number of shares
of Company Common Stock purchasable upon exercise hereof shall be
appropriately adjusted so that Grantee shall receive upon exercise of the
Option and payment of the aggregate Option Price hereunder the number and
class of shares or other securities or property that Grantee would have
received in respect of Company Common Stock if the Option had been
exercised in full immediately prior to such event, or the record date
therefor, as applicable.

            (c) OPTION PRICE ADJUSTMENT. Whenever the number of shares of
Company Common Stock subject to this Option are adjusted pursuant to
Subsection 8(a) or 8(b) the Option Price shall be adjusted by multiplying
the Option Price by a fraction, the numerator of which shall be equal to
the aggregate number of shares of Company Common Stock purchasable under
the Option prior to the adjustment and the denominator of which shall be
equal to the aggregate number of shares of Company Common Stock
purchasable under the Option immediately after the adjustment.

            9. REGISTRATION RIGHTS. The Company will, if requested by the
Grantee at any time and from time to time within two (2) years of a
Triggering Event (the "Registration Period"), as expeditiously as
practicable prepare, file and cause to be made effective up to two
registration statements under the Securities Act if such registration is
necessary or desirable in order to permit the offering, sale and delivery
of any or all shares of Company Common Stock (or other Option Securities)
that have been acquired by or are issuable to the Grantee upon exercise
of the Option in accordance with the intended method of sale or other
disposition stated by the Grantee, including, at the sole discretion of
the Company, a "shelf" registration statement under Rule 415 under the
Securities Act or any successor provision, and the Company will use all
reasonable efforts to qualify such shares or other Option Securities
under any applicable state securities laws. Without the Grantee's prior
written consent, no other securities may be included in any such
registration. The Grantee agrees to use all reasonable efforts to cause,
and to cause any underwriters of any sale or other disposition to cause,
any sale or other disposition pursuant to such registration statement to
be effected on a widely distributed basis so that upon consummation
thereof no purchaser or transferee will own beneficially more than 5% of
the then outstanding voting power of the Company. The Company will use
all reasonable efforts to cause each such registration statement to
become effective, to obtain all consents or waivers of other parties
which are required therefor and to keep such registration statement
effective for such period not in excess of 180 days from the day such
registration statement first becomes effective as may be reasonably
necessary to effect such sale or other disposition. The obligations of
the Company hereunder to file a registration statement and to maintain
its effectiveness may be suspended for one or more periods of time not
exceeding ninety (90) days in the aggregate if the Board of Directors of
the Company shall have determined in good faith that the filing of such
registration or the maintenance of its effectiveness would require
disclosure of nonpublic information that would materially and adversely
affect the Company. The expenses associated with the preparation and
filing of any such registration statement pursuant to this Section 9 and
any sale covered thereby (including any fees related to blue sky
qualifications and filing fees in respect of the Securities and Exchange
Commission or the National Association of Securities Dealers, Inc.)
("Registration Expenses") will be for the account of the Company except
for underwriting discounts or commissions or brokers' fees in respect to
shares of Company Common Stock (or other Option Securities) to be sold by
the Grantee and the fees and disbursements of the Grantee's counsel;
provided, however, that the Company will not be required to pay for any
Registration Expenses with respect to such registration if the
registration request is subsequently withdrawn at the request of the
Grantee unless the Grantee agrees to forfeit its right to request one
registration; provided further, however, that, if at the time of such
withdrawal the Grantee has learned of a material adverse change in the
results of operations, condition, business or prospects of the Company
from that known to the Grantee at the time of its request and has
withdrawn the request with reasonable promptness following disclosure by
the Company of such material adverse change, then the Grantee will not be
required to pay any of such expenses and will retain all remaining rights
to request registration. The Grantee will provide all information
reasonably requested by the Company for inclusion in any registration
statement to be filed hereunder. If during the Registration Period the
Company shall propose to register under the Securities Act the offering,
sale and delivery of Company Common Stock for cash for its own account or
for any other stockholder of the Company pursuant to a firm underwriting,
it will, in addition to the Company's other obligations under this
Section 9, allow the Grantee the right to participate in such
registration provided that the Grantee participates in the underwriting;
provided, however, that, if the managing underwriter of such offering
advises the Company in writing that in its opinion the number of shares
of Company Common Stock (or other Option Securities) requested to be
included in such registration exceeds the number which can be sold in
such offering, the Company will, after fully including therein all
shares of Company Common Stock and/or Option Securities to be sold by the
Company, include the shares of Company Common Stock (or other Option
Securities) requested to be included therein by Grantee pro rata (based
on the number of shares of Company Common Stock or other Option
Securities intended to be included therein) with the shares of Company
Common Stock or other Option Securities intended to be included therein
by Persons other than the Company. In connection with any offering, sale
and delivery of Company Common Stock pursuant to a registration statement
effected pursuant to this Section 9, the Company and the Grantee will
provide each other and each underwriter of the offering with customary
representations, warranties and covenants, including covenants of
indemnification and contribution. For purposes of determining whether two
requests have been made under this Section 9, only requests relating to a
registration statement that has become effective under the Securities Act
and pursuant to which the Grantee has disposed of all shares of Company
Common Stock covered thereby in the manner contemplated therein will be
counted. The registration rights granted under this Section 9 are subject
to and are limited by any registration rights previously granted by the
Company and the Grantee acknowledges the registration rights granted
under this Section 9 shall be construed subject to any such limitations.

            10. REPURCHASE OF OPTION AND OPTION SHARES. (a) Within ten
(10) Business Days following the occurrence of a Repurchase Event (as
defined herein), the Company shall (i) deliver an offer (an "Option
Repurchase Offer") to repurchase the Option from Grantee at a price (the
"Option Repurchase Price") equal to the amount by which (A) the Competing
Transaction Price (as defined below) exceeds (B) the Option Price,
multiplied by the maximum number of shares for which the Option may then
be exercised by the Grantee, and (ii) deliver an offer (an "Option Share
Repurchase Offer") to repurchase the Option Shares from each owner of
Option Shares from time to time (each, an "Owner") at a price (the
"Option Share Repurchase Price") equal to the amount by which (A) the
Competing Transaction Price exceeds (B) the Option Price, multiplied by
the number of Option Shares then held by such Owner. The term "Competing
Transaction Price" shall mean, as of any date for the determination
thereof, the price per share of Common Stock paid pursuant to the
consummation of any Acquisition Proposal (such consummated Acquisition
Proposal being referred to herein as a "Competing Transaction") or, in
the event of a sale of assets of the Company, the last per-share sale
price of Company Common Stock on the fourth trading day following the
announcement of such sale. If the consideration paid or received in the
Competing Transaction shall be other than in cash, the per share value of
such consideration (on a fully diluted basis) shall be determined by a
nationally recognized investment banking firm selected by Grantee and
reasonably acceptable to the Company, which determination shall be
conclusive for all purposes of this Agreement.

            (b) REPURCHASE REQUEST. Upon the occurrence of a Repurchase
Event and whether or not the Company shall have made an Option Repurchase
Offer or Option Share Repurchase Offer under Section 10(a), (i) at the
request (the date of such request being the "Option Repurchase Request
Date") of Grantee delivered prior to the Option Termination Date, the
Company shall repurchase the Option from Grantee at the Option Repurchase
Price and (ii) at the request (the date of such request being the "Option
Share Repurchase Request Date") of any Owner delivered prior to the
Option Termination Date, the Company shall repurchase such number of the
Option Shares (to the extent clearly identifiable as such) from the Owner
as the Owner shall designate at the Option Share Repurchase Price.

            (c) REPURCHASE PROCEDURES. Grantee or the Owner, as the case
may be, may (i) accept the Company's Option Repurchase Offer or Option
Share Repurchase Offer under Subsection 10(a) or (ii) exercise its right
to require the Company to repurchase the Option or any Option Shares, as
the case may be, pursuant to Subsection 10(b) by a written notice or
notices stating that Grantee or the Owner, as the case may be, elects to
accept such offer or to require the Company to repurchase the Option or
the Option Shares in accordance with the provisions of this Section 10.
As promptly as practicable, and in any event within five (5) Business
Days, after the surrender to the Company of this Agreement or
Certificates for Option Shares, as applicable, following receipt of a
notice under this Subsection 10(c), the Company shall deliver or cause to
be delivered to Grantee the Option Repurchase Price or to the Owner the
Option Share Repurchase Price, as the case may be.

            (d) REGULATORY APPROVALS. The Company hereby undertakes to
use its best efforts to obtain all required regulatory and legal
approvals and to file any required notices as promptly as practicable in
order to accomplish any repurchase contemplated by this Section 10.
Nonetheless, to the extent that the Company is prohibited under
applicable Law from repurchasing the Option or any Option Shares in full,
the Company shall immediately so notify Grantee or the Owner and
thereafter deliver or cause to be delivered, from time to time, to
Grantee or the Owner, as appropriate, the portion of the Option
Repurchase Price and the Option Share Repurchase Price, respectively,
that it is no longer prohibited from delivering, within five (5) Business
Days after the date on which the Company is no longer so prohibited;
provided, however, that if the Company at any time after delivery of a
notice of repurchase pursuant to Section 10(b) hereof is prohibited under
applicable Law, from delivering to Grantee or the Owner, as appropriate,
the Option Repurchase Price or the Option Share Repurchase Price,
respectively, in full, Grantee or the Owner, as appropriate, may revoke
its notice of repurchase of the Option or the Option Shares,
respectively, either in whole or in part whereupon, in the case of a
revocation in part, the Company shall promptly (i) deliver to Grantee or
the Owner, as appropriate, that portion of the Option Repurchase Price or
the Option Share Repurchase Price that the Company is not prohibited from
delivering after taking into account any such revocation and (ii)
deliver, as appropriate, either (A) to Grantee, a new Agreement
evidencing the right of Grantee to purchase that number of shares of
Company Common Stock equal to the number of shares of Company Common
Stock purchasable immediately prior to the delivery of the notice of
repurchase less the number of shares of Company Common Stock covered by
the portion of the Option repurchased or (B) to the Owner, a certificate
for the number of Option Shares covered by the revocation. If an Option
Termination Event shall have occurred prior to the date of the notice by
the Company described in the first sentence of this Subsection 10(d), or
shall be scheduled to occur at any time before the expiration of a period
ending on the thirtieth day after such date, Grantee shall nonetheless
have the right to exercise the Option until the expiration of such thirty
(30) day period.

            (e) DEFINITION. The term "Repurchase Event" shall mean a
Triggering Event followed by the consummation of any transaction included
in the definition of Competing
Transaction.

            (f) COMPETING TRANSACTION. Notwithstanding anything to the
contrary in Subsections 2(a), the delivery of a notice by Grantee or an
Owner under Subsection 10(b) hereof specifying that such notice is based
on the Company's public announcement of the execution of an agreement
providing for a Competing Transaction shall be deemed to constitute an
election to exercise the Option, as to the number of Option Shares not
heretofore purchased pursuant to one or more prior exercises of the
Option, on the fifth Business Day following the public announcement of
the consummation of the transaction contemplated by such agreement, in
which event a closing shall occur with respect to such unpurchased Option
Shares in accordance with Subsection 2(e).

            (g) REPRESENTATIONS. In connection with any purchase/sale of
the Option or the Option Shares pursuant to this Section 10, the Grantee
and/or the Owner, as applicable, will be required to represent and
warrant to the Company that such Person is the owner of the Option/Option
Shares being purchased, free and clear of all adverse claims and that
such Person will deliver good title to such Option/Option Shares to the
Company, free and clear of all adverse claims, upon consummation of any
purchase/sale pursuant to this Section 10.

            11. SUBSTITUTE OPTION IN THE EVENT OF CORPORATE CHANGE. (a)
In the event that prior to an Option Termination Event, the Company shall
enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or one of its Subsidiaries, and shall not be the
continuing or surviving corporation of such consolidation or merger, (ii)
to permit any person, other than Grantee or one of its Subsidiaries, to
merge into the Company and the Company shall be the continuing or
surviving corporation, but, in connection with such merger, the then
outstanding shares of Company Common Stock shall be changed into or
exchanged for stock or other securities of any other person or cash or
any other property or the then outstanding shares of Company Common Stock
shall after such merger represent less than 50% of the outstanding shares
and share equivalents of the merged company, or (iii) to sell or
otherwise transfer all or substantially all of its assets to any person,
other than Grantee or one of its Subsidiaries, then, and in each such
case, the agreement governing such transaction shall make proper
provision so that the Option shall, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be
converted into, or exchanged for, an option (the "Substitute Option"), at
the election of Grantee, of either (x) the Acquiring Corporation (as
hereinafter defined) or (y) any person that controls the Acquiring
Corporation subsequent to the consolidation, merger or sale in question.

            (b) DEFINITIONS. The following terms have the meanings
indicated:

                  (1) "Acquiring Corporation" shall mean (i) the
            continuing or surviving corporation of a consolidation or
            merger with the Company (if other than the Company), (ii) the
            Company in a merger in which the Company is the continuing or
            surviving person, and (iii) the transferee of all or
            substantially all of the Company's assets.

                  (2) "Substitute Common Stock" shall mean the common
            stock issued by the Company upon exercise of the Substitute
            Option.

                  (3) "Assigned Value" shall mean the Competing Transaction
            Price, as defined in Section 10.

                  (4) "Average Price" shall mean the average closing
            price of a share of the Substitute Common Stock for the
            ninety (90) days immediately preceding the consolidation,
            merger or sale in question; provided that if the Company is
            the issuer of the Substitute Option, the Average Price shall
            be computed with respect to a share of common stock issued by
            the Company, the Person merging into the Company or by any
            company which controls or is controlled by such Person
            subsequent to the consideration merger or sale in question,
            as Grantee may elect.

            (c) TERMS OF THE SUBSTITUTE OPTION. The Substitute Option
shall have the same terms as the Option; provided that if the terms of
the Substitute Option cannot, for legal reasons, be the same as the
Option, such terms shall be as similar as possible and in no event less
advantageous to Grantee. The issuer of the Substitute Option shall also
enter into an agreement with Grantee in substantially the same form as
this Agreement, which agreement shall be applicable to the Substitute
Option.

            (d) SUBSTITUTE COMMON STOCK. The Substitute Option shall be
exercisable for such number of shares of Substitute Common Stock as is
equal to the Assigned Value multiplied by the number of shares of Company
Common Stock for which the Option is then exercisable, divided by the
Average Price. The exercise price of the Substitute Option per share of
Substitute Common Stock shall then be equal to the Option Price
multiplied by a fraction, the numerator of which shall be the number of
shares of Company Common Stock for which the Option is then exercisable
and the denominator of which shall be the number of shares of Substitute
Common Stock for which the Substitute Option is exercisable.

            (e) LIMITATION. In no event, pursuant to any of the foregoing
paragraphs, shall the Substitute Option be exercisable for more than ten
percent (10%) of the shares of Substitute Common Stock issued and
outstanding prior to exercise of the Substitute
Option.

            (f) ASSUMPTION OF OBLIGATION. The Company shall not enter
into any transaction described in Subsection 11(a) unless the Acquiring
Corporation and any person that controls the Acquiring Corporation assume
in writing all the obligations of the Company hereunder.

            12. EXTENSION OF TIME FOR REGULATORY APPROVALS. The periods
related to exercise of the Option and the other rights of Grantee
hereunder shall be extended (i) to the extent necessary to obtain all
regulatory approvals for the exercise of such rights, and for the
expiration of all statutory waiting periods and (ii) to the extent
necessary to avoid liability under Section 10(b) of the Exchange Act by
reason of such exercise.

            13. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The
Company hereby represents and warrants to Grantee as follows:

            (a) AUTHORITY. The Company has full corporate power and
authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby
have been duly and validly authorized by the Board of Directors of the
Company and no other corporate proceedings on the part of the Company are
necessary to authorize this Agreement or to consummate the transactions
so contemplated. This Agreement has been duly and validly executed and
delivered by the Company. This Agreement is the valid and legally binding
obligation of the Company, enforceable against the Company in accordance
with its terms subject to bankruptcy, insolvency, reorganization,
moratorium or similar laws now or hereafter in effect relating to
creditors' rights generally or to general principles of equity.

            (b) CORPORATE ACTION. The Company has taken all necessary
corporate action to authorize and reserve and to permit it to issue, and
at all times from the date hereof through the termination of this
Agreement in accordance with its terms will have reserved for issuance
upon the exercise of the Option, that number of shares of Company Common
Stock equal to the maximum number of shares of Company Common Stock at
any time and from time to time issuable hereunder, and all such shares of
Company Common Stock, upon issuance pursuant hereto, will be duly
authorized, validly issued, fully paid, nonassessable, and will be
delivered free and clear of all Liens and not subject to any preemptive
rights.

            (c) NO CONFLICT. The execution and delivery of this Agreement
does not, and the consummation of the transactions contemplated hereby
will not, conflict with, or result in any violation pursuant to any
provisions of the Certificate of Incorporation or by-laws of the Company
or any Subsidiary of the Company, subject to obtaining any approvals or
consents contemplated hereby, result in any violation of any loan or
credit agreement, note, mortgage, indenture, lease, plan or other
agreement, obligation, instrument, permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to the Company or any Subsidiary of the Company or
their respective properties or assets.

            (d) ANTI-TAKEOVER STATUTES. The provisions of Section 203 of
the General Corporation Law of the State of Delaware will not, prior to
the termination of this Agreement, apply to this Agreement or the
transactions contemplated hereby and thereby. The Company has taken, and
will in the future take, all steps necessary to irrevocably exempt the
transactions contemplated by this Agreement from any other applicable
state takeover law and from any applicable charter or contractual
provision containing change of control or anti-takeover provisions.

            14. ASSIGNMENT. The Company may not assign any of its rights
or obligations under this Agreement or the Option created hereunder to
any other Person, without the express written consent of Grantee. Grantee
may not assign any of its rights or obligations under this Agreement or
the Option created hereunder to any other Person without the consent of
the Company (which consent will not be unreasonably withheld).

            15. APPLICATION FOR REGULATORY APPROVAL. Each of Grantee and
the Company will use its best efforts to make all filings with, and to
obtain consents of, all third parties and governmental authorities
necessary to the consummation of the transactions contemplated by this
Agreement, including without limitation making application to list the
shares of Company Common Stock issuable hereunder on the Nasdaq National
Market of The Nasdaq Stock Market, Inc. upon official notice of issuance.

            16. SPECIFIC PERFORMANCE. The parties hereto acknowledge that
damages would be an inadequate remedy for a breach of this Agreement by
either party hereto and that the obligations of the parties hereto shall
be enforceable by either party hereto through injunctive or other
equitable relief.

            17. SEPARABILITY OF PROVISIONS. If any term, provision,
covenant or restriction contained in this Agreement is held by a court or
a federal or state regulatory agency of competent jurisdiction to be
invalid, void or unenforceable, the remainder of the terms, provisions
and covenants and restrictions contained in this Agreement shall remain
in full force and effect, and shall in no way be affected, impaired or
invalidated.

            18. NOTICES. All notices, claims, demands and other
communications hereunder shall be deemed to have been duly given or made
when delivered in person, by registered or certified mail (postage

Agreement.

            19. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware,
regardless of the laws that might otherwise govern under applicable
principles of conflicts of laws thereof.

            20. COUNTERPARTS. This Agreement may be executed in two or
more counterparts, each of which will be deemed to be an original, but
all of which shall constitute one and the same agreement.

            21. DEFINITIONS. Capitalized terms used and not defined
herein shall have the meanings set forth in the Merger Agreement.

            22. EXPENSES. Except as otherwise expressly provided herein
or in the Merger Agreement, each of the parties hereto shall bear and pay
all costs and expenses incurred by it or on its behalf in connection with
the transactions contemplated hereunder, including fees and expenses of
its own financial consultants, investment bankers, accountants and
counsel.

            23. ENTIRE AGREEMENT. Except as otherwise expressly provided
herein or in the Merger Agreement, this Agreement contains the entire
agreement between the parties with respect to the transactions
contemplated hereunder and supersedes all prior arrangements or
understandings with respect thereof, written or oral. The terms and
conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted
assigns. Nothing in this Agreement, expressed or implied, is intended to
confer upon any party, other than the parties hereto, and their
respective successors and permitted assigns, any rights, remedies,
obligations or liabilities under or by reason of this Agreement, except
as expressly provided herein. Any provision of this Agreement may be
waived only in writing at any time by the party that is entitled to the
benefits of such provision. This Agreement may not be modified, amended,
altered or supplemented except upon the execution and delivery of a
written agreement executed by the parties hereto.

            24. FIRST REFUSAL. If the Grantee shall desire to sell,
assign, transfer or otherwise dispose of all or any of the shares of
Company Common Stock or other Option Securities acquired by it pursuant
to the Option, it will give the Company written notice of the proposed
transaction (an "Offeror's Notice"), identifying the proposed transferee,
accompanied by a copy of a binding to purchase such shares of Company
Common Stock, Options or other Option Securities signed by such
transferee and setting forth the terms of the proposed transaction. An
Offeror's Notice will be deemed an offer by the Grantee to the Company,
which may be accepted, in whole but not in part, within ten (10) Business
Days of the receipt of such Offeror's Notice, on the same terms and
conditions and at the same price at which the Grantee is proposing to
transfer such shares of Company Common Stock, Options or other Option
Securities to such transferee. The purchase of any such shares of Company
Common Stock, Options or other Option Securities by the Company will be
settled within ten (10) Business Days of the date of the acceptance of
the offer and the purchase price will be paid to the Grantee in
immediately available funds. In the event of the failure or refusal of
the Company to purchase all the shares of Company Common Stock, Options
or other Option Securities covered by an Offeror's Notice, the Grantee
may, within sixty (60) days from the date of the Offeror's Notice, sell
all, but not less than all, of such shares of Company Common Stock,
Options or other Option Securities to the proposed transferee at no less
than the price specified and on terms no more favorable than those set
forth in the Offeror's Notice; provided, however, that the provisions of
this sentence will not limit the rights the Grantee may otherwise have if
the Company has accepted the offer contained in the Offeror's Notice and
wrongfully refuses to purchase the shares of Company Common Stock,
Options or other Option Securities subject thereto. The requirements of
this Section 24 will not apply to (a) any disposition as a result of
which the proposed transferee would own beneficially not more than 2% of
the outstanding voting power of the Company, (b) any disposition of
Company Common Stock or other Option Securities by a Person to whom the
Grantee has assigned its rights under the Option with the consent of the
Company, (c) any sale by means of a public offering registered under the
Securities Act or (d) any transfer to a wholly-owned Subsidiary of the
Grantee which agrees in writing to be bound by the terms hereof.

            25. LIMITATION OF GRANTEE PROFIT. (a) Notwithstanding any
other provision of this Agreement, in no event shall Grantee's Total
Profit (as hereinafter defined) exceed in the aggregate $7,278,000 and,
if it otherwise would exceed such amount, Grantee, at its sole election,
shall either (i) reduce the number of shares of Company Common Stock
subject to this Option, (ii) deliver to the Company for cancellation
Option Shares previously purchased by Grantee, (iii) pay cash to the
Company, or (iv) any combination thereof, so that Grantee's actually
realized Total Profit shall not exceed in the aggregate $7,278,000 after
taking into account the foregoing actions.

            (b) As used herein, the term "Total Profit" shall mean the
sum of (i) (x) the amount (before taxes but net of reasonable and
customary commissions paid or payable in connection with such
transaction) received or receivable by the Grantee pursuant to the sale
of Option Shares (or any other securities or property into which such
Option Shares are converted or exchanged) to any unaffiliated Person(s)
or to the Company with respect to such Option Shares (or any other
securities or property into which such Option Shares are converted or
exchanged), less (y) Grantee's purchase price for such Option Shares (or
any other securities or property into which such Option Shares are
converted or exchanged), (ii) any amounts (before taxes but net of
reasonable and customary commissions paid or payable in connection with
such transaction) received or receivable by the Grantee on the transfer
of the Option (or any portion thereof) to any unaffiliated Person(s) (if
permitted hereunder) or to the Company, (iii) any equivalent amount(s)
with respect to the Substitute Option, and (iv) the amount received by
the Grantee pursuant to Subsection 9.2(b) of the Merger Agreement.

            26. FURTHER ASSURANCES. In the event of any exercise of the
Option by Grantee, the Company and Grantee shall execute and deliver all
other documents and instruments and take all other action that may be
reasonably necessary in order to consummate the transactions provided for
by such exercise. Nothing contained in this Agreement shall be deemed to
authorize the Company or Grantee to breach any provision of the Merger
Agreement.


            IN WITNESS WHEREOF, each of the parties hereto has caused
this Agreement to be executed as of the date first written above by their
respective officers thereunto duly authorized.

is competent to execute and deliver this Voting Agreement, to perform it
obligations hereunder and to consummate the transactions contemplated
hereby. This Voting Agreement has been duly and validly executed and
delivered by such Stockholder and, assuming the due authorization,
execution and delivery by Acquiror, constitutes a legal, valid and
binding obligation of such Stockholder, enforceable against such
Stockholder in accordance with its terms except that (i) the

Agreement by such Stockholder does not, and the performance of this
Voting Agreement by such Stockholder shall not result in any breach of or
constitute a default (or an event that with notice or lapse of time or

termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or encumbrance, on any of the Shares or Options
pursuant to, any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise or other instrument or obligation to
which such Stockholder is a party or by which such Stockholder or the
Shares or Options are bound or affected.

      Section 3.3  Title to the Shares. The Shares and Options held by
such Stockholder are owned free and clear of all security interests,
liens, claims, pledges, options, rights of first refusal, agreements,
limitations on such Stockholder's voting rights, charges and other

effective, with respect to the Shares.


                               ARTICLE IV

                              Miscellaneous

      Section 4.1  Termination. This Agreement shall terminate upon the
earliest to occur of (a) the termination of the Merger Agreement in
accordance with its terms or (b) the Effective Time (as defined in the
Merger Agreement). Upon such termination, no party shall have any further
obligations or liabilities hereunder, provided that no such termination
shall relieve any party from liability for any breach of this Agreement
prior to such termination.

      Section 4.2  Enforcement of Agreement. The parties hereto agree that
irreparable damage would occur in the event that any of the provisions of
this Voting Agreement were not performance in accordance with its
specified terms or were otherwise breached. It is accordingly agreed that
the parties shall be entitled to an injunction or injunctions to prevent
breaches of this Voting Agreement and to specific performance of the
terms and provisions hereof in addition to any other remedy to which they
are entitled at law or in equity.

      Section 4.3  Successors and Affiliates. This Voting Agreement shall
inure to the benefit of and shall be binding upon the parties hereto and
their respective heirs, legal representatives and assigns. If any
Stockholder shall at any time hereafter acquire ownership of, or voting
power with respect to, any additional Shares in any manner, whether by
the exercise of any Options or any securities or rights convertible into
or exchangeable for shares of Company Common Stock, operation of law or
otherwise, such Shares shall be held subject to all of the terms and
provisions of this Voting Agreement. Without limiting the foregoing, each
Stockholder specifically agrees that the obligations of such Stockholder
hereunder shall not be terminated by operation of law, whether by death
or incapacity of the Stockholder or otherwise.

      Section 4.4  Entire Agreement. This Voting Agreement constitutes the
entire agreement among Acquiror and the Stockholders with respect to the
subject matter hereof and supersedes all prior agreements and
understandings, both written and oral, among Acquiror and the
Stockholders with respect to the subject matter hereof.

except by an instrument in writing signed by the parties hereto.

      Section 4.7  Waivers. Except as provided in this Voting Agreement,
no action taken pursuant to this Voting Agreement, including without
limitation any investigation by or on behalf of any party, shall be
deemed to constitute a waiver by the party taking such action of
compliance with any representations, warranties, covenants or agreements
contained in this Voting Agreement. The wavier by any party hereto of a
breach of any provision hereunder shall not operate or be construed as a
wavier of any prior or subsequent breach of the same or any other
provision hereunder.

      Section 4.8  Severability. If any term of other provision of this
Voting Agreement is invalid, illegal or incapable of being enforced by
any rule of law, or public policy, all other conditions and provisions of
this Voting Agreement shall nevertheless remain in full force and effect.
Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall
