     Item 5.  OTHER EVENTS

               On February 10, 1994, Advanced Technology
     Laboratories, Inc. (the "Company" or "ATL") announced that
     it had entered into a Merger Agreement with Interspec, Inc.
     whereby Interspec would become a wholly owned subsidiary of
     ATL through an exchange of 0.03835 shares of ATL stock for
     each share of Interspec stock.

               The merger is subject to customary conditions,
     including approval by the shareholders of ATL and Interspec. 
     The exchange ratio of 0.3835 is based on the purchase method
     of accounting used for this transaction.  However, if it is
     determined that the transaction qualifies for "pooling of
     interests" accounting treatment, the parties to the merger
     agreement have agreed that the exchange ratio will be
     adjusted to 0.4130 of a share of an ATL share for each share
     of Interspec stock.

               ATL and Interspec currently anticipate that the
     transaction will close in the latter part of the second
     quarter.

                  Delaware corporation ("Sub"), and a wholly
                  owned subsidiary of Parent, and INTERSPEC,
                  INC., a Pennsylvania corporation (the
                  "Company").


               WHEREAS the respective Boards of Directors of
     Parent, Sub and the Company have approved the merger of Sub
     into the Company (the "Merger"), upon the terms and subject
     to the conditions set forth in this Agreement, whereby each

               WHEREAS the Merger requires the approval of a
     majority of votes cast by the holders of shares of the
     Company Common Stock entitled to vote thereon at the meeting
     of holders of Company Common Stock to be called therefor
     (the "Company Stockholder Approval");

     certain representations, warranties, covenants and
     agreements in connection with the Merger and also to
     prescribe various conditions to the Merger; and

               WHEREAS, for Federal income tax purposes, it is
     intended that the Merger shall qualify as a reorganization
     under the provisions of Section 368(a) of the Internal
     Revenue Code of 1986, as amended (the "Code");

     PBCL and the DGCL.

               SECTION 1.02.  Closing.  The closing of the Merger

     reads in its entirety as follows:  "The total number of
     shares of all classes of stock which the corporation shall
     have authority to issue is 100 shares of Common Stock, par
     value $1.00 per share." and, as so amended, such articles of

     Effective Time of the Merger, by virtue of the Merger and

                                                                4

     without any action on the part of the holder of any shares
     of Company Common Stock or any shares of capital stock of
     Sub:

               (a)  Capital Stock of Sub.  Each issued and
          outstanding share of capital stock of Sub shall be
          converted into and become one fully paid and
          nonassessable share of Common Stock, par value $1.00
          per share, of the Surviving Corporation.

               (b)  Cancellation of Treasury Stock and Parent-
          Owned Stock.  Each share of Company Common Stock that
          is owned by the Company or by any subsidiary (as
          defined in Section 8.03) of the Company and each share
          of Company Common Stock that is owned by Parent, Sub or
          any other subsidiary of Parent shall automatically be
          cancelled and retired and shall cease to exist, and no
          Parent Common Stock or other consideration shall be
          delivered in exchange therefor.

               (c)  Conversion of Company Common Stock.  Subject
          to Section 2.02(e), each issued and outstanding share
          of Company Common Stock (other than shares to be
          cancelled in accordance with Section 2.01(b)) shall be
          converted into the right to receive 0.3835 of a fully
          paid and nonassessable share of Parent Common Stock
          (the "Exchange Ratio").  Pursuant to the Rights
          Agreement (as defined in Section 3.02(b)), one Right
          (as defined in the Rights Agreement) will be attached
          to each share of Parent Common Stock issued in
          connection with the Merger upon conversion of Company
          Common Stock.  As of the Effective Time of the Merger,
          all such shares of Company Common Stock shall no longer
          be outstanding and shall automatically be cancelled and
          retired and shall cease to exist, and each holder of a
          certificate representing any such shares of Company
          Common Stock shall cease to have any rights with
          respect thereto, except the right to receive the shares
          of Parent Common Stock and any cash in lieu of
          fractional shares of Parent Common Stock to be issued
          or paid in consideration therefor upon surrender of
          such certificate in accordance with Section 2.02,
          without interest. 

               (d)  Dissenting Shares.  Notwithstanding anything
          in this Agreement to the contrary, shares of Company
          Common Stock outstanding immediately prior to the
          Effective Time of the Merger held by a holder (if any)


                             Page 12 of 90

                                                                5

          who is entitled to demand, and who properly demands,
          appraisal for such shares in accordance with
          Section 1571 of the PBCL ("Dissenting Shares") shall
          not be converted into a right to receive Parent Common
          Stock and any cash in lieu of fractional shares of
          Parent Common Stock unless such holder fails to perfect
          or otherwise loses such holder's right to appraisal, if
          any.  If, after the Effective Time of the Merger, such
          holder fails to perfect or loses any such right to
          appraisal, such shares shall be treated as if they had
          been converted as of the Effective Time of the Merger
          into the right to receive Parent Common Stock pursuant
          to Section 2.01(c) and the cash in lieu of fractional
          shares of Parent Common Stock specified in
          Section 2.02(e).  The Company shall give prompt notice
          to Parent of any demands received by the Company for
          appraisal of shares of Company Common Stock, and Parent
          shall have the right to participate in and direct all
          negotiations and proceedings with respect to such
          demands.  The Company shall not, except with the prior
          written consent of Parent, make any payment with
          respect to, or settle or offer to settle, any such
          demands.

               SECTION 2.02.  Exchange of Certificates. 
     (a)  Exchange Agent.  As of the Effective Time of the
     Merger, Parent shall deposit with First Chicago Trust
     Company of New York or such other bank or trust company as
     may be designated by Parent (the "Exchange Agent"), for the
     benefit of the holders of shares of Company Common Stock,
     for exchange in accordance with this Article II, through the
     Exchange Agent, certificates representing the shares of
     Parent Common Stock (such shares of Parent Common Stock,
     together with any dividends or distributions with respect
     thereto, being hereinafter referred to as the "Exchange
     Fund") issuable pursuant to Section 2.01 in exchange for
     outstanding shares of Company Common Stock.

               (b)  Exchange Procedures.  As soon as reasonably
     practicable after the Effective Time of the Merger, the
     Exchange Agent shall mail to each holder of record of a
     certificate or certificates which immediately prior to the
     Effective Time of the Merger represented outstanding shares
     of Company Common Stock (the "Certificates") whose shares
     were converted into the right to receive shares of Parent
     Common Stock pursuant to Section 2.01, (i) a letter of
     transmittal (which shall specify that delivery shall be
     effected, and risk of loss and title to the Certificates


                             Page 13 of 90 

     <PAGE>14

                                                                6

     shall pass, only upon delivery of the Certificates to the
     Exchange Agent and shall be in such form and have such other
     provisions as Parent may reasonably specify) and
     (ii) instructions for use in effecting the surrender of the
     Certificates in exchange for certificates representing
     shares of Parent Common Stock.  Upon surrender of a
     Certificate for cancellation to the Exchange Agent or to
     such other agent or agents as may be appointed by Parent,
     together with such letter of transmittal, duly executed, and
     such other documents as may reasonably be required by the
     Exchange Agent, the holder of such Certificate shall be
     entitled to receive in exchange therefor a certificate
     representing that number of whole shares of Parent Common
     Stock which such holder has the right to receive pursuant to
     the provisions of this Article II and cash in lieu of
     fractional shares of Parent Common Stock as contemplated by
     this Section 2.02, and the Certificate so surrendered shall
     forthwith be cancelled.  In the event of a transfer of
     ownership of Company Common Stock which is not registered in
     the transfer records of the Company, a certificate
     representing the proper number of shares of Parent Common
     Stock may be issued to a person other than the person in
     whose name the Certificate so surrendered is registered, if
     such Certificate shall be properly endorsed or otherwise be
     in proper form for transfer and the person requesting such
     payment shall pay any transfer or other taxes required by
     reason of the issuance of shares of Parent Common Stock to a
     person other than the registered holder of such Certificate
     or establish to the satisfaction of Parent that such tax has
     been paid or is not applicable.  Until surrendered as
     contemplated by this Section 2.02, each Certificate shall be
     deemed at any time after the Effective Time of the Merger to
     represent only the right to receive upon such surrender the
     certificate representing shares of Parent Common Stock and
     cash in lieu of any fractional shares of Parent Common Stock
     as contemplated by this Section 2.02.  No interest will be
     paid or will accrue on any cash payable in lieu of any
     fractional shares of Parent Common Stock.

               (c)  Distributions with Respect to Unexchanged
     Shares.  No dividends or other distributions with respect to
     Parent Common Stock with a record date after the Effective
     Time of the Merger shall be paid to the holder of any
     unsurrendered Certificate with respect to the shares of
     Parent Common Stock represented thereby, and no cash payment
     in lieu of fractional shares shall be paid to any such
     holder pursuant to Section 2.02(e), in each case until the
     surrender of such Certificate in accordance with this


                             Page 14 of 90 

     <PAGE>15

                                                                7

     Article II.  Subject to the effect of applicable laws,
     following surrender of any such Certificate, there shall be
     paid to the holder of the certificate representing whole
     shares of Parent Common Stock issued in exchange therefor,
     without interest, (i) at the time of such surrender, the
     amount of any cash payable in lieu of a fractional share of
     Parent Common Stock to which such holder is entitled
     pursuant to Section 2.02(e) and the amount of dividends or
     other distributions with a record date after the Effective
     Time of the Merger theretofore paid with respect to such
     whole shares of Parent Common Stock, and (ii) at the
     appropriate payment date, the amount of dividends or other
     distributions with a record date after the Effective Time of
     the Merger but prior to such surrender and with a payment
     date subsequent to such surrender payable with respect to
     such whole shares of Parent Common Stock.

               (d)  No Further Ownership Rights in Company Common
     Stock.  All shares of Parent Common Stock issued upon the
     surrender for exchange of Certificates in accordance with
     the terms of this Article II (including any cash paid
     pursuant to Section 2.02(c) or 2.02(e)) shall be deemed to
     have been issued (and paid) in full satisfaction of all
     rights pertaining to the shares of Company Common Stock
     theretofore represented by such Certificates, subject,
     however, to the Surviving Corporation's obligation to pay
     any dividends or make any other distributions with a record
     date prior to the Effective Time of the Merger which may
     have been declared or made by the Company on such shares of
     Company Common Stock in accordance with the terms of this
     Agreement or prior to the date of this Agreement and which
     remain unpaid at the Effective Time of the Merger, and there
     shall be no further registration of transfers on the stock
     transfer books of the Surviving Corporation of the shares of
     Company Common Stock which were outstanding immediately
     prior to the Effective Time of the Merger.  If, after the
     Effective Time of the Merger, Certificates are presented to
     the Surviving Corporation or the Exchange Agent for any
     reason, they shall be cancelled and exchanged as provided in
     this Article II, except as otherwise provided by law.

               (e)  No Fractional Shares.  (i)  No certificates
     or scrip representing fractional shares of Parent Common
     Stock shall be issued upon the surrender for exchange of
     Certificates, and such fractional share interests will not
     entitle the owner thereof to vote or to any rights of a
     stockholder of Parent.

                                                                8

               (ii)  As promptly as practicable following the
     Effective Time of the Merger, the Exchange Agent shall
     determine the excess of (x) the number of shares of Parent
     Common Stock delivered to the Exchange Agent by Parent
     pursuant to Section 2.02(a) over (y) the aggregate number of
     whole shares of Parent Common Stock to be distributed to
     holders of the Certificates pursuant to Section 2.02(b)
     (such excess being hereinafter referred to as the "Excess
     Shares").  As soon after the Effective Time of the Merger as
     practicable, the Exchange Agent, as agent for the holders of
     the Certificates, shall sell the Excess Shares at then
     prevailing prices on the National Association of Securities
     Dealers, Inc. Automated Quotations National Market System
     ("NASDAQ/NMS"), all in the manner provided in
     paragraph (iii) of this Section 2.02(e).

               (iii)  The sale of the Excess Shares by the
     Exchange Agent shall be executed on the NASDAQ/NMS through
     one or more member firms of the National Association of
     Securities Dealers, Inc. and shall be executed in round lots
     to the extent practicable.  Until the net proceeds of such
     sale or sales have been distributed to the holders of the
     Certificates, the Exchange Agent will hold such proceeds in
     trust for the holders of the Certificates (the "Common
     Shares Trust").  Parent shall pay all commissions, transfer
     taxes and other out-of-pocket transaction costs, including
     the expenses and compensation of the Exchange Agent,
     incurred in connection with such sale of the Excess Shares. 
     The Exchange Agent shall determine the portion of the Common
     Shares Trust to which each holder of a Certificate shall be
     entitled, if any, by multiplying the amount of the aggregate
     net proceeds comprising the Common Shares Trust by a
     fraction, the numerator of which is the amount of the
     fractional share interest to which such holder of a
     Certificate is entitled and the denominator of which is the
     aggregate amount of fractional share interests to which all
     holders of the Certificates are entitled.

               (iv)  As soon as practicable after the
     determination of the amount of cash, if any, to be paid to
     holders of the Certificates in lieu of any fractional share
     interests, the Exchange Agent shall make available such
     amounts, without interest, to such holders of the
     Certificates.

               (f)  Termination of Exchange Fund and Common
     Shares Trust.  Any portion of the Exchange Fund and Common
     Shares Trust which remains undistributed to the holders of

                                                                9

     the Certificates for six months after the Effective Time of
     the Merger shall be delivered to Parent, upon demand, and
     any holders of the Certificates who have not theretofore
     complied with this Article II shall thereafter look only to
     Parent for payment of their claim for Parent Common Stock,
     any cash in lieu of fractional shares of Parent Common Stock
     and any dividends or distributions with respect to Parent
     Common Stock.

               (g)  No Liability.  None of Parent, Sub, the
     Company or the Exchange Agent shall be liable to any person
     in respect of any shares of Parent Common Stock (or
     dividends or distributions with respect thereto) or cash
     from the Exchange Fund or the Common Shares Trust delivered
     to a public official pursuant to any applicable abandoned
     property, escheat or similar law.  If any Certificates shall
     not have been surrendered prior to seven years after the
     Effective Time of the Merger (or immediately prior to such
     earlier date on which any shares of Parent Common Stock, any
     cash in lieu of fractional shares of Parent Common Stock or
     any dividends or distributions with respect to Parent Common
     Stock in respect of such Certificate would otherwise escheat
     to or become the property of any Governmental Entity (as
     defined in Section 3.01(d)), any such shares, cash,
     dividends or distributions in respect of such Certificate
     shall, to the extent permitted by applicable law, become the
     property of the Surviving Corporation, free and clear of all
     claims or interest of any person previously entitled
     thereto.

               (h)  Investment of Exchange Fund and Common Shares
     Trust.  The Exchange Agent shall invest any cash included in
     the Exchange Fund and the Common Shares Trust, as directed
     by Parent, on a daily basis.  Any interest and other income
     resulting from such investments shall be paid to Parent.

                              ARTICLE III

                    Representations and Warranties

               SECTION 3.01.  Representations and Warranties of
     the Company.  Except as set forth on the Disclosure Schedule
     delivered by the Company to Parent prior to the execution of
     this Agreement (the "Company Disclosure Schedule"), the
     Company represents and warrants to Parent and Sub as
     follows:

               (a)  Organization, Standing and Corporate Power. 
          Each of the Company and each of its subsidiaries is a
          corporation duly organized, validly existing and in
          good standing under the laws of the jurisdiction in
          which it is incorporated and has the requisite
          corporate power and authority to carry on its business
          as now being conducted.  Each of the Company and each
          of its subsidiaries is duly qualified or licensed to do
          business and is in good standing in each jurisdiction
          in which the nature of its business or the ownership or
          leasing of its properties makes such qualification or
          licensing necessary, other than in such jurisdictions
          where the failure to be so qualified or licensed
          individually or in the aggregate would not have a
          material adverse effect on the Company.  The Company
          has delivered to Parent complete and correct copies of
          its articles of incorporation and by-laws and the
          certificates of incorporation and by-laws of its
          subsidiaries, in each case as amended to the date
          hereof.

               (b)  Subsidiaries.  Exhibit 22 to the Company's
          Form 10-K for the fiscal year ended November 30, 1992,
          lists each subsidiary of the Company.  All the
          outstanding shares of capital stock of each such
          subsidiary have been validly issued and are fully paid
          and nonassessable and are owned by the Company, free
          and clear of all pledges, claims, liens, charges,
          encumbrances and security interests of any kind or
          nature whatsoever (collectively, "Liens").  Except for
          the capital stock of its subsidiaries, the Company does
          not own, directly or indirectly, any capital stock or
          other ownership interest in any corporation,
          partnership, joint venture or other entity.

               (c)  Capital Structure.  The authorized capital
          stock of the Company consists of 10,000,000 shares of


                             Page 18 of 90

                                                               11

          Company Common Stock and 400,000 shares of preferred
          stock, par value $.01 per share.  At the close of
          business on February 8, 1994, (i) 6,274,877 shares of
          Company Common Stock and no shares of preferred stock
          were issued and outstanding, (ii) 10,390 shares of
          Company Common Stock were held by the Company in its
          treasury, (iii) 580,168 shares of Company Common Stock
          were reserved for issuance pursuant to the Stock Plans
          (as defined in Section 5.06) and (iv) 928,571 shares of
          Company Common Stock were reserved for issuance upon
          conversion of the Company's 11% Convertible
          Subordinated Notes (the "Convertible Notes").  At the
          close of business on February 8, 1994, there was
          $6,500,000 aggregate principal amount outstanding of
          the Convertible Notes, which are convertible into
          shares of Company Common Stock at the option of the
          holder thereof at an exchange price of $7 per share of
          Company Common Stock.  Except as set forth above, at
          the close of business on February 8, 1994, no shares of
          capital stock or other voting securities of the Company
          were issued, reserved for issuance or outstanding.  All
          outstanding shares of capital stock of the Company are,
          and all shares which may be issued pursuant to the
          Stock Plans will be, when issued, duly authorized,
          validly issued, fully paid and nonassessable and not
          subject to preemptive rights.  There are no bonds,
          debentures, notes or other indebtedness of the Company
          having the right to vote (or, except for the
          Convertible Notes, convertible into, or exchangeable
          for, securities having the right to vote) on any
          matters on which stockholders of the Company may vote. 
          Except as set forth above, as of the date hereof, there
          are no outstanding securities, options, warrants,
          calls, rights, commitments, agreements, arrangements or
          undertakings of any kind to which the Company or any of
          its subsidiaries is a party or by which any of them is
          bound obligating the Company or any of its subsidiaries
          to issue, deliver or sell, or cause to be issued,
          delivered or sold, additional shares of capital stock
          or other voting securities of the Company or of any of
          its subsidiaries or obligating the Company or any of
          its subsidiaries to issue, grant, extend or enter into
          any such security, option, warrant, call, right,
          commitment, agreement, arrangement or undertaking.  As
          of the date of this Agreement, there are not any
          outstanding contractual obligations of the Company or
          any of its subsidiaries to repurchase, redeem or
          otherwise acquire any shares of capital stock of the

     <PAGE>20

                                                               12

          Company or any of its subsidiaries.  There are not any
          outstanding contractual obligations of the Company to
          vote or to dispose of any shares of the capital stock
          of any of its subsidiaries.

               (d)  Authority; Noncontravention.  The Company has
          the requisite corporate power and authority to enter
          into this Agreement and, subject to the Company
          Stockholder Approval with respect to the Merger, to
          consummate the transactions contemplated by this

                                                               14

          their respective dates, the SEC Documents complied in
          all material respects with the requirements of the
          Securities Act of 1933, as amended (the "Securities
          Act"), or the Exchange Act, as the case may be, and the
          rules and regulations of the SEC promulgated thereunder
          applicable to such SEC Documents, and none of the SEC
          Documents contained any untrue statement of a material
          fact or omitted to state a material fact required to be
          stated therein or necessary in order to make the
          statements therein, in light of the circumstances under
          which they were made, not misleading.  Except to the
          extent that information contained in any SEC Document
          has been revised or superseded by a later Filed SEC
          Document (as defined in Section 3.01(g)), none of the
          SEC Documents contains any untrue statement of a
          material fact or omits to state any material fact
          required to be stated therein or necessary in order to
          make the statements therein, in light of the
          circumstances under which they were made, not
          misleading.  The financial statements of the Company
          included in the SEC Documents comply as to form in all
          material respects with applicable accounting
          requirements and the published rules and regulations of
          the SEC with respect thereto, have been prepared in
          accordance with generally accepted accounting
          principles (except, in the case of unaudited
          statements, as permitted by Form 10-Q of the SEC)
          applied on a consistent basis during the periods
          involved (except as may be indicated in the notes
          thereto) and fairly present the consolidated financial
          position of the Company and its consolidated
          subsidiaries as of the dates thereof and the
          consolidated results of their operations and cash flows
          (or changes in financial position prior to the approval
          of Financial Accounting Standards Board Statement of
          Financial Accounting Standards No. 95) for the periods
          then ended (subject, in the case of unaudited
          statements, to normal year-end audit adjustments). 
          Other than with respect to ERISA (as defined in
          Section 3.01(j) below) and tax matters, which are
          addressed by Sections 3.01(j) and 3.01(k),
          respectively, except as set forth in the Filed SEC
          Documents, neither the Company nor any of its
          subsidiaries has any liabilities or obligations of any
          nature (whether accrued, absolute, contingent or
          otherwise and whether or not required by generally
          accepted accounting principles to be recognized or
          disclosed on a consolidated balance sheet of the

          Company and its consolidated subsidiaries or in the
          notes thereto) which individually or in the aggregate
          could reasonably be expected to have a material adverse
          effect on the Company.

               (f)  Information Supplied.  None of the
          information supplied or to be supplied by the Company
          specifically for inclusion or incorporation by
          reference in (i) the registration statement on Form S-4
          to be filed with the SEC by Parent in connection with
          the issuance of Parent Common Stock in the Merger (the
          "Form S-4") will, at the time the Form S-4 is filed
          with the SEC, at any time it is amended or supplemented
          or at the time it becomes effective under the
          Securities Act, contain any untrue statement of a
          material fact or omit to state any material fact
          required to be stated therein or necessary to make the
          statements therein not misleading or (ii) the Joint
          Proxy Statement will, at the date it is first mailed to
          the Company's stockholders or at the time of the
          Stockholders Meeting (as defined in Section 5.01(b)),
          contain any untrue statement of a material fact or omit
          to state any material fact required to be stated
          therein or necessary in order to make the statements
          therein, in light of the circumstances under which they
          are made, not misleading.  The Joint Proxy Statement
          will comply as to form in all material respects with
          the requirements of the Exchange Act and the rules and
          regulations thereunder, except that no representation
          or warranty is made by the Company with respect to
          statements made or incorporated by reference therein
          based on information supplied by Parent or Sub
          specifically for inclusion or incorporation by
          reference in the Joint Proxy Statement.

               (g)  Absence of Certain Changes or Events.  Except
          as disclosed on the Company Disclosure Schedule or in
          the SEC Documents filed and publicly available prior to
          the date of this Agreement (the "Filed SEC Documents"),
          since the date of the most recent audited financial
          statements included in the Filed SEC Documents, the
          Company has conducted its business only in the ordinary
          course, and there has not been (i) any material adverse
          change in the Company, (ii) any declaration, setting
          aside or payment of any dividend or other distribution
          (whether in cash, stock or property) with respect to
          any of the Company's capital stock, (iii) any split,
          combination or reclassification of any of its capital

          stock or any issuance or the authorization of any
          issuance of any other securities in respect of, in lieu
          of or in substitution for shares of its capital stock,
          (iv) (x) any granting by the Company or any of its
          subsidiaries to any executive officer or other employee
          of the Company or any of its subsidiaries of any
          increase in compensation, except in the ordinary course
          of business consistent with prior practice or as was
          required under employment agreements in effect as of
          the date of the most recent audited financial
          statements included in the Filed SEC Documents, (y) any
          granting by the Company or any of its subsidiaries to
          any such executive officer of any increase in severance
          or termination pay, except as was required under any
          employment, severance or termination agreements in
          effect as of the date of the most recent audited
          financial statements included in the Filed SEC
          Documents or (z) any entry by the Company or any of its
          subsidiaries into any employment, severance or
          termination agreement with any such executive officer,
          (v) any damage, destruction or loss, whether or not
          covered by insurance, that has or could reasonably be
          expected to have a material adverse effect on the
          Company or (vi) any change in accounting methods,
          principles or practices by the Company materially
          affecting its assets, liabilities or business, except
          insofar as may have been required by a change in
          generally accepted accounting principles.

               (h)  Litigation.  Except as disclosed in the Filed
          SEC Documents, there is no suit, action or proceeding
          pending or, to the knowledge of the Company, threatened
          against or affecting the Company or any of its
          subsidiaries (and the Company is not aware of any basis
          for any such suit, action or proceeding) that 
          individually or in the aggregate could reasonably be
          expected to (i) have a material adverse effect on the
          Company, (ii) impair the ability of the Company to
          perform its obligations under this Agreement or
          (iii) prevent the consummation of any of the
          transactions contemplated by this Agreement, nor is
          there any judgment, decree, injunction, rule or order
          of any Governmental Entity or arbitrator outstanding
          against the Company or any of its subsidiaries having,
          or which is reasonably likely to have, any effect
          referred to in clause (i), (ii) or (iii) above.

               (i)  Absence of Changes in Benefit Plans.  Except
          as disclosed in the Filed SEC Documents, since the date
          of the most recent audited financial statements
          included in the Filed SEC Documents, there has not been
          any adoption or amendment in any material respect by
          the Company or any of its subsidiaries of any
          collective bargaining agreement or any bonus, pension,
          profit sharing, deferred compensation, incentive
          compensation, stock ownership, stock purchase, stock
          option, phantom stock, retirement, vacation, severance,
          disability, death benefit, hospitalization, medical or
          other plan, arrangement or understanding (whether or
          not legally binding) providing benefits to any current
          or former employee, officer or director of the Company
          or any of its subsidiaries.  Except as disclosed in the
          Filed SEC Documents, there exist no employment,
          consulting, severance, termination or indemnification
          agreements, arrangements or understandings between the
          Company or any of its subsidiaries and any current or
          former employee, officer or director of the Company or
          any of its subsidiaries.

               (j)  ERISA Compliance.  (i)  The Company
          Disclosure Schedule contains a list and brief
          description of each "employee pension benefit plan" (as
          defined in Section 3(2) of the Employee Retirement
          Income Security Act of 1974, as amended ("ERISA")),
          each "employee welfare benefit plan" (as defined in
          Section 3(1) of ERISA) (sometimes referred to herein as
          a "Welfare Plan"), each stock option, stock purchase,
          deferred compensation plan or arrangement and each
          other employee fringe benefit plan or arrangement
          maintained, contributed to or required to be maintained
          or contributed to by the Company, any of its
          subsidiaries or any other person or entity that,
          together with the Company, is treated as a single
          employer under Section 414(b), (c), (m) or (o) of the
          Code (each, a "Commonly Controlled Entity") for the
          benefit of any current or former employees, officers,
          directors or independent contractors of the Company or
          any of its subsidiaries (collectively, "Benefit
          Plans").  The Company has delivered to Parent true,
          complete and correct copies of (w) each Benefit Plan
          (or, in the case of any unwritten Benefit Plans,
          descriptions thereof), (x) the most recent annual
          report on Form 5500 filed with the Internal Revenue
          Service with respect to each Benefit Plan (if any such
          report was required), (y) the most recent summary plan


                             Page 25 of 90 

     <PAGE>26

                                                               18

          description for each Benefit Plan for which such
          summary plan description is required and (z) each
          currently effective trust agreement and insurance or
          group annuity contract relating to any Benefit Plan.

              (ii)  Each Benefit Plan has been administered in
          all material respects in accordance with its terms. 
          The Company, its subsidiaries and all the Benefit Plans
          are in compliance in all material respects with the
          applicable provisions of ERISA and the Code.  All
          reports, returns and similar documents with respect to
          the Benefit Plans required to be filed with any
          governmental agency or distributed to any Benefit Plan
          participant have been duly and timely filed or
          distributed.  To the knowledge of the Company, there
          are no investigations by any governmental agency,
          termination proceedings or other claims (except claims
          for benefits payable in the normal operation of the
          Benefit Plans), suits or proceedings against or
          involving any Benefit Plan or asserting any rights or
          claims to benefits under any Benefit Plan that could
          give rise to any material liability, and, to the
          knowledge of the Company, there are not any facts that
          could give rise to any material liability in the event
          of any such investigation, claim, suit or proceeding.

             (iii)  (1) All contributions to, and payments from,
          the Benefit Plans that may have been required to be
          made in accordance with the terms of the Benefit Plans,
          any applicable collective bargaining agreement and,
          when applicable, Section 302 of ERISA or Section 412 of
          the Code, have been timely made, (2) there has been no
          application for or waiver of the minimum funding
          standards imposed by Section 412 of the Code with
          respect to any Benefit Plan that is an "employee
          pension benefit plan" (as defined in Section 3(2) of
          ERISA) (sometimes referred to herein as a "Pension
          Plan") and (3) no Pension Plan had an "accumulated
          funding deficiency" within the meaning of Section
          412(a) of the Code as of the end of the most recently
          completed plan year.  

              (iv)  Each Pension Plan has been the subject of a
          determination letter from the Internal Revenue Service
          to the effect that such Pension Plan is qualified and
          exempt from Federal income taxes under Sections 401(a)
          and 501(a), respectively, of the Code; no such
          determination letter has been revoked, and, to the


                             Page 26 of 90 

     <PAGE>27

                                                               19

          knowledge of the Company, revocation has not been
          threatened; and such Pension Plan has not been amended
          since the effective date of its most recent
          determination letter in any respect that would
          adversely affect its qualification, materially increase
          its costs or require security under Section 307 of
          ERISA.  The Company has delivered to Parent a copy of
          the most recent determination letter received with
          respect to each Pension Plan for which such a letter
          has been issued, as well as a copy of any pending
          application for a determination letter.  The Company
          has also provided to Parent a list of all Pension Plan
          amendments as to which a favorable determination letter
          has not yet been received.  To the knowledge of the
          Company, no event has occurred that could subject any
          Pension Plan to tax under Section 511 of the Code.

               (v)  To the knowledge of the Company, (1) no
          "prohibited transaction" (as defined in Section 4975 of
          the Code or Section 406 of ERISA) has occurred that
          involves the assets of any Benefit Plan; (2) no
          prohibited transaction has occurred that could subject
          the Company, any of its subsidiaries, any employee of
          the Company or its subsidiaries or, to the knowledge of
          the Company, a trustee, administrator or other
          fiduciary of any trust created under any Benefit Plan
          to the tax or penalty on prohibited transactions
          imposed by Section 4975 of the Code or the sanctions
          imposed under Title I of ERISA; (3) no Pension Plan has
          been terminated or has been the subject of a
          "reportable event" (as defined in Section 4043 of ERISA
          and the regulations thereunder); and (4) none of the
          Company or any trustee, administrator or other
          fiduciary of any Benefit Plan or any agent of any of
          the foregoing has engaged in any transaction or acted
          in a manner that could, or failed to act so as to,
          subject the Company or any trustee, administrator or
          other fiduciary to any liability for breach of
          fiduciary duty under ERISA or any other applicable law.

              (vi)  As of the most recent valuation date for each
          Pension Plan that is a "defined benefit pension plan"
          (as defined in Section 3(35) of ERISA) (a "Defined
          Benefit Plan"), there was not any amount of "unfunded
          benefit liabilities" (as defined in Section 4001(a)(18)
          of ERISA) under such Defined Benefit Plan, and the
          Company is not aware of any facts or circumstances that
          would materially change the funded status of any such


                             Page 27 of 90 

     <PAGE>28

                                                               20

          Defined Benefit Plan.  The Company has furnished to
          Parent the most recent actuarial report or valuation
          with respect to each Defined Benefit Plan.  The
          information supplied to the actuary by the Company and
          any of its subsidiaries for use in preparing those
          reports or valuations was complete and accurate in all
          material respects and the Company has no reason to
          believe that the conclusions expressed in those reports
          or valuations are incorrect.

             (vii)  No Commonly Controlled Entity has incurred
          any liability to an "employee pension benefit plan" (as
          defined in Section 3(2) of ERISA) (other than for
          contributions not yet due) or to the Pension Benefit
          Guaranty Corporation (other than for the payment of
          premiums not yet due), which liability has not been
          fully paid as of the date hereof.

            (viii)  No Commonly Controlled Entity has (a) engaged
          in a transaction described in Section 4069 of ERISA
          that could subject the Company to liability at any time
          after the date hereof or (b) acted in a manner that
          could, or failed to act so as to, result in fines,
          penalties, taxes or related charges under
          (x) Section 502(c)(i) or (l) of ERISA, (y) Section 4071
          of ERISA or (z) Chapter 43 of the Code.

              (ix)  No Commonly Controlled Entity is required to
          contribute to any "multiemployer plan" (as defined in
          Section 4001(a)(3) of ERISA) or has withdrawn from any
          multiemployer plan where such withdrawal has resulted
          or would result in any "withdrawal liability" (as
          defined in Section 4201 of ERISA) that has not been
          fully paid.

               (x)  The list of Welfare Plans on the Company
          Disclosure Schedule discloses whether each Welfare Plan
          is (i) unfunded, (ii) funded through a "welfare benefit
          fund", as such term is defined in Section 419(e) of the
          Code, or other funding mechanism or (iii) insured. 
          Each such Welfare Plan may be amended or terminated
          without material liability to the Company at any time
          after the Effective Time of the Merger.  The Company
          and its subsidiaries comply in all material respects
          with the applicable requirements of Section 4980B(f) of
          the Code with respect to each Benefit Plan that is a
          group health plan, as such term is defined in Section
          5000(b)(1) of the Code.

                                                               21

             (xi)  Except as disclosed on the Company Disclosure
          Schedule, no employee of the Company will be entitled
          to any additional benefits or any acceleration of the
          time of payment or vesting of any benefits under any
          Benefit Plan as a result of the transactions
          contemplated by this Agreement.

               (k)  Taxes.  (i)  Each of the Company and its
          subsidiaries has filed all tax returns and reports
          required to be filed by it or requests for extensions
          to file such returns or reports have been timely filed,
          granted and have not expired, except to the extent that 
          such failures to file or to have extensions granted
          that remain in effect individually and in the aggregate
          would not have a material adverse effect on the
          Company.  All returns filed by the Company and each of
          its subsidiaries are complete and accurate in all
          material respects to the knowledge of the Company.  The
          Company and each of its subsidiaries has paid (or the
          Company has paid on its behalf) all taxes shown as due
          on such returns, and the most recent financial
          statements contained in the Filed SEC Documents reflect
          an adequate reserve for all taxes payable by the
          Company and its subsidiaries for all taxable periods
          and portions thereof accrued through the date of such
          financial statements.

             (ii)  No deficiencies for any taxes have been
          proposed, asserted or assessed against the Company or
          any of its subsidiaries that are not adequately
          reserved for, except for deficiencies that individually
          or in the aggregate would not have a material adverse
          effect on the Company, and no requests for waivers of
          the time to assess any such taxes have been granted or
          are pending.  None of the Federal income tax returns of
          the Company and each of its subsidiaries consolidated
          in such returns have been examined by and settled with
          the United States Internal Revenue Service.  The
          statute of limitations on assessment or collection of
          any taxes due from the Company or any of its
          subsidiaries has expired for all taxable years of the
          Company or any of its subsidiaries through November 30,
          1989.

            (iii)  Neither the Company nor any of its
          subsidiaries has taken any action or has any knowledge
          of any fact or circumstance that is reasonably likely
          to prevent the transactions contemplated hereby,


                             Page 29 of 90 

     <PAGE>30

                                                               22

          including the Merger, from qualifying as a
          reorganization within the meaning of Section 368(a) of
          the Code.

              (iv)  No real estate transfer tax or real estate
          gains tax will be imposed by the Commonwealth of
          Pennsylvania or any political subdivision thereof as a
          consequence of the Merger or any other transaction
          contemplated by this Agreement.

               (v)  As used in this Agreement, "taxes" shall
          include all Federal, state, local and foreign income,
          property, sales, excise and other taxes, tariffs or
          governmental charges of any nature whatsoever.

               (l)  No Excess Parachute Payments; Section 162(m)
          of the Code.  (i)  Any amount that could be received
          (whether in cash or property or the vesting of
          property) as a result of any of the transactions
          contemplated by this Agreement by any employee, officer
          or director of the Company or any of its affiliates who
          is a "disqualified individual" (as such term is defined
          in proposed Treasury Regulation Section 1.280G-1) under
          any employment, severance or termination agreement,
          other compensation arrangement or Benefit Plan
          currently in effect would not be characterized as an
          "excess parachute payment" (as such term is defined in
          Section 280G(b)(1) of the Code).  

               (ii)  The disallowance of a deduction under
          Section 162(m) of the Code for employee renumeration
          will not apply to any amount paid or payable by the
          Company or any subsidiary of the Company under any
          contract, plan, program, arrangement or understanding.

               (m)  Voting Requirements.  The affirmative vote of
          a majority of the votes cast by the holders of the
          shares of Company Common Stock entitled to vote thereon
          at the Stockholders Meeting with respect to the
          approval of the Merger is the only vote of the holders
          of any class or series of the Company's capital stock
          necessary to approve this Agreement and the
          transactions contemplated by this Agreement.

               (n)  State Takeover Statutes.  The Board of
          Directors of the Company has approved the execution and
          delivery of this Agreement and the consummation of the
          Merger and the other transactions contemplated by this


                             Page 30 of 90 

     <PAGE>31

                                                               23

          Agreement, and such approval is sufficient to render
          inapplicable to this Agreement, the Merger and the
          other transactions contemplated by this Agreement the
          provisions of Subchapter F of the PBCL.  To the best of
          the Company's knowledge, no other state takeover
          statute or similar statute or regulation applies or
          purports to apply to the Merger, this Agreement or any
          of the transactions contemplated by this Agreement and
          no provision of the articles of incorporation, by-laws
          or other governing instruments of the Company or any of
          its subsidiaries would, directly or indirectly,
          restrict or impair the ability of Parent to vote, or
          otherwise to exercise the rights of a stockholder with
          respect to, shares of the Company and its subsidiaries
          that may be acquired or controlled by Parent.

               (o)  Labor Matters.  There are no collective
          bargaining or other labor union agreements to which the
          Company or any of its subsidiaries is a party or by
          which any of them is bound.  To the best knowledge of
          the Company, since December 1, 1992, neither the
          Company nor any of its subsidiaries has encountered any
          labor union organizing activity, or had any actual or
          threatened employee strikes, work stoppages, slowdowns
          or lockouts.

               (p)  Brokers; Schedule of Fees and Expenses.  No
          broker, investment banker, financial advisor or other
          person, other than Merrill Lynch & Co. ("Merrill
          Lynch"), the fees and expenses of which will be paid by
          the Company, is entitled to any broker's, finder's,
          financial advisor's or other similar fee or commission
          in connection with the transactions contemplated by
          this Agreement based upon arrangements made by or on
          behalf of the Company.  The estimated fees and expenses
          incurred and to be incurred by the Company in
          connection with this Agreement and the transactions
          contemplated by this Agreement (including the fees of
          the Company's legal counsel) are set forth on the
          Company Disclosure Schedule.

               (q)  Opinion of Financial Advisor.  The Company
          has received the oral opinion of Merrill Lynch to the
          effect that, based upon and subject to assumptions made
          by Merrill Lynch in rendering such opinion and based
          upon such other matters as they consider relevant, as
          of the date of this Agreement, the Exchange Ratio is

     <PAGE>32

                                                               24

          fair to the Company's stockholders from a financial
          point of view.

               (r)  [Intentionally omitted]

               (s)  Compliance with Applicable Laws.  (i)  Each
          of the Company and its subsidiaries has in effect all
          Federal, state, local and foreign governmental
          approvals, authorizations, certificates, filings,
          franchises, licenses, notices, permits and rights
          ("Permits") necessary for it to own, lease or operate
          its properties and assets and to carry on its business
          as now conducted, and there has occurred no default
          under any such Permit, except for the lack of Permits
          and for defaults under Permits which lack or default
          individually or in the aggregate would not have a
          material adverse effect on the Company.  Except as
          disclosed in the Filed SEC Documents, the Company and
          its subsidiaries are in compliance with all applicable
          statutes, laws, ordinances, rules, orders and
          regulations of any Governmental Entity, except for
          possible noncompliance which individually or in the
          aggregate would not have a material adverse effect on
          the Company.

               (ii)  To the best of the Company's knowledge, each
          of the Company and its subsidiaries is, and has been,
          and each of the Company's former subsidiaries, while
          subsidiaries of the Company, was in compliance with all
          applicable Environmental Laws, except for possible
          noncompliance which individually or in the aggregate
          would not have a material adverse effect on the
          Company.  The term "Environmental Laws" means any
          Federal, state, local or foreign statute, code,
          ordinance, rule, regulation, policy, guideline, permit,
          consent, approval, license, judgment, order, writ,
          decree, directive, injunction or other authorization,
          including the requirement to register underground
          storage tanks, relating to:  (A) emissions, discharges,
          Releases (as defined below) or threatened Releases of
          Hazardous Material (as defined below) into the
          environment, including into ambient air, soil,
          sediments, land surface or subsurface, buildings or
          facilities, surface water, groundwater, publicly-owned
          treatment works, septic systems or land; (B) the
          generation, treatment, storage, disposal, use,
          handling, manufacturing, transportation or shipment of



                             Page 32 of 90

                                                               25

          Hazardous Material; or (C) pollution of the environment
          or the protection of human health or safety.

              (iii)  During the period of ownership or operation
          by the Company and its subsidiaries of any of their
          respective current or previously-owned properties,
          there have been no Releases of Hazardous Material in,
          on, under or affecting such properties or, to the
          knowledge of the Company, any surrounding site, except
          in each case for those which individually or in the
          aggregate would not have a material adverse effect on
          the Company.  Prior to the period of ownership or
          operation by the Company and its subsidiaries of any of
          their respective current or previously-owned
          properties, to the knowledge of the Company, no
          Hazardous Material was generated, treated, stored,
          disposed of, used, handled or manufactured at, or
          transported, shipped or disposed of from, such current
          or previously-owned properties, and there were no
          Releases of Hazardous Material in, on, under or
          affecting any such property or any surrounding site,
          except in each case for those which individually or in
          the aggregate would not have a material adverse effect
          on the Company.  The term "Release" has the meaning set
          forth in 42 U.S.C. Section 9601(22).  The term
          "Hazardous Material" means (1) hazardous materials,
          pollutants, contaminants, constituents, medical wastes,
          hazardous or infectious wastes and hazardous substances
          as those terms are defined in the following statutes
          and their implementing regulations:  the Hazardous
          Materials Transportation Act, 49 U.S.C. Section 1801 et
          seq., the Resource Conservation and Recovery Act, 42
          U.S.C. Section 6901 et seq., the Comprehensive
          Environmental Response, Compensation and Liability Act,
          as amended by the Superfund Amendments and
          Reauthorization Act, 42 U.S.C. Section 9601 et seq.,
          the Occupational Safety and Health Act, 29 U.S.C.
          Section 651 et seq., the Clean Water Act, 33 U.S.C.
          Section 1251 et seq., the Toxic Substances Control Act,
          15 U.S.C. Section 2601 et seq. and the Clean Air Act,
          42 U.S.C. Section 7401 et seq., (2) petroleum,
          including crude oil and any fractions thereof,
          (3) natural gas, synthetic gas and any mixtures
          thereof, (4) asbestos and/or asbestos-containing
          material and (5) PCBs, or materials or fluids
          containing PCBs.

               (t)  Contracts; Debt Instruments.  (i)  Except as
          disclosed in the Filed SEC Documents or on the Company
          Disclosure Schedule, there are no contracts or

                             Page 33 of 90

                                                               26

          agreements that are material to the business,
          properties, assets, condition (financial or otherwise),
          results of operations or prospects of the Company and
          its subsidiaries taken as a whole.  Neither the Company
          nor any of its subsidiaries is in violation of or in
          default under (nor does there exist any condition which
          upon the passage of time or the giving of notice would
          cause such a violation of or default under) any loan or
          credit agreement, note, bond, mortgage, indenture,
          lease, permit, concession, franchise, license or any
          other contract, agreement, arrangement or understanding
          to which it is a party or by which it or any of its
          properties or assets is bound, except for violations or
          defaults that individually or in the aggregate would

          Company or any of its subsidiaries in an aggregate
          principal amount in excess of $25,000 is outstanding or
          may be incurred and (y) the respective principal
          amounts currently outstanding thereunder.  For purposes
          of this Agreement, "indebtedness" shall mean, with
          respect to any person, without duplication, (A) all
          obligations of such person for borrowed money, or with
          respect to deposits or advances of any kind to such
          person, (B) all obligations of such person evidenced by
          bonds, debentures, notes or similar instruments,
          (C) all obligations of such person upon which interest
          charges are customarily paid, (D) all obligations of
          such person under conditional sale or other title
          retention agreements relating to property purchased by

          or assumed as the deferred purchase price of property
          or services (excluding obligations of such person to
          creditors for raw materials, inventory, services and

          guarantees and arrangements having the economic effect
          of a guarantee of such person of any indebtedness of
          any other person.

               (u)  Title to Properties.  (i)  Each of the
          Company and each of its subsidiaries has good and
          marketable title to, or valid leasehold interests in,
          all its material properties and assets except for such
          as are no longer used or useful in the conduct of its
          businesses or as have been disposed of in the ordinary
          course of business and except for defects in title,
          easements, restrictive covenants and similar
          encumbrances or impediments that individually or in the
          aggregate would not materially interfere with its
          ability to conduct its business as currently conducted. 
          All such material assets and properties, other than
          assets and properties in which the Company or any of
          its subsidiaries has leasehold interests, are free and
          clear of all Liens, except for Liens that individually
          or in the aggregate would not materially interfere with
          the ability of the Company and its subsidiaries to
          conduct business as currently conducted.

               (ii)  Each of the Company and each of its
          subsidiaries has complied in all material respects with
          the terms of all material leases to which it is a party
          and under which it is in occupancy, and all such leases
          are in full force and effect.  Each of the Company and
          each of its subsidiaries enjoys peaceful and
          undisturbed possession under all such material leases.

               (v)  Intellectual Property.  To the best of the
          Company's knowledge, the Company and its subsidiaries
          own, or are validly licensed or otherwise have the
          right to use, all patents, patent rights, trademarks,
          trademark rights, trade names, trade name rights,
          service marks, service mark rights, copyrights and
          other proprietary intellectual property rights and
          computer programs (collectively, "Intellectual Property
          Rights") which are material to the conduct of the
          business of the Company and its subsidiaries taken as a
          whole.  The Company Disclosure Schedule sets forth a
          description of all Intellectual Property Rights which
          are material to the conduct of the business of the
          Company and its subsidiaries taken as a whole.  Except
          as set forth on the Company Disclosure Schedule, no
          claims are pending or, to the knowledge of the Company,
          threatened that the Company or any of its subsidiaries


                             Page 35 of 90 

     <PAGE>36

                                                               28

          is infringing or otherwise adversely affecting the
          rights of any person with regard to any Intellectual
          Property Right.  To the knowledge of the Company,
          except as set forth on the Company Disclosure Schedule,
          no person is infringing the rights of the Company or
          any of its subsidiaries with respect to any
          Intellectual Property Right.

               SECTION 3.02.  Representations and Warranties of
     Parent and Sub.  Except as set forth on the Disclosure
     Schedule delivered by Parent to the Company prior to the
     execution of this Agreement (the "Parent Disclosure
     Schedule"), Parent and Sub represent and warrant to the
     Company as follows:

               (a)  Organization, Standing and Corporate Power. 
          Each of Parent and Sub is a corporation duly organized,
          validly existing and in good standing under the laws of
          the jurisdiction in which it is incorporated and has
          the requisite corporate power and authority to carry on
          its business as now being conducted.  Each of Parent
          and Sub is duly qualified or licensed to do business
          and is in good standing in each jurisdiction in which
          the nature of its business or the ownership or leasing
          of its properties makes such qualification or licensing
          necessary, other than in such jurisdictions where the
          failure to be so qualified or licensed individually or
          in the aggregate would not have a material adverse
          effect on Parent.  Parent has delivered to the Company
          complete and correct copies of its certificate of
          incorporation and by-laws and the certificate of
          incorporation and by-laws of Sub, in each case as
          amended to the date hereof.

               (b)  Capital Structure.  The authorized capital
          stock of Parent consists of 50,000,000 shares of Parent
          Common Stock and 6,000,000 shares of preferred stock,
          par value $1 per share.  At the close of business on
          February 8, 1994, (i) 10,491,489 shares of Parent
          Common Stock and no shares of preferred stock, par
          value $1 per share, were issued and outstanding,
          (ii) 760,457 shares of Parent Common Stock were held by
          Parent in its treasury, (iii) 1,601,983 shares of
          Parent Common Stock were reserved for issuance pursuant
          to the Company's 1986 Amended and Restated Option,
          Restricted Stock, Stock Appreciation Right and
          Performance Unit Plan, the Amended Westmark
          International Incorporated Incentive Savings and Stock

          Ownership Plan and Trust, the Amended and Restated
          Retirement Plan, the Management Incentive Compensation
          Plan, the 1992 Option, Stock Appreciation Right,
          Restricted Stock, Stock Grant and Performance Unit Plan
          (the "1992 Option Plan"), the Amended and Restated
          Nonofficer Employee Option, Restricted Stock and Stock
          Grant Plan, the 1992 Nonofficer Employee Stock Option
          Plan and the Stock Option Plan for Nonemployee
          Directors (the "Parent Stock Plans") and
          (iv) 500,000 shares of Series A Participating
          Cumulative Preferred Stock ("Parent Preferred Stock")
          (subject to increase and adjustment as set forth in the
          Rights Agreement and the Certificate of Designations
          attached as an exhibit thereto) were reserved for
          issuance in connection with the rights (the "Rights")
          to purchase shares of Parent Preferred Stock pursuant
          to the Amended and Restated Rights Agreement dated as
          of June 26, 1992, between Parent and First Chicago
          Trust Company of New York, as Rights Agent (the "Rights
          Agreement").  Except as set forth above, at the close
          of business on February 8, 1994, no shares of capital
          stock or other voting securities of Parent were issued,
          reserved for issuance or outstanding.  All outstanding
          shares of capital stock of Parent are, and all shares
          which may be issued pursuant to this Agreement will be,
          when issued, duly authorized, validly issued, fully
          paid and nonassessable and not subject to preemptive
          rights.  There are no bonds, debentures, notes or other
          indebtedness of Parent having the right to vote (or
          convertible into, or exchangeable for, securities
          having the right to vote) on any matters on which
          stockholders of Parent may vote.  Except as set forth
          above or as otherwise contemplated by this Agreement,
          as of the date of this Agreement, there are no
          securities, options, warrants, calls, rights,
          commitments, agreements, arrangements or undertakings
          of any kind to which Parent or any of its subsidiaries
          is a party or by which any of them is bound obligating
          Parent or any of its subsidiaries to issue, deliver or
          sell, or cause to be issued, delivered or sold,
          additional shares of capital stock or other voting
          securities of Parent or obligating Parent or any of its
          subsidiaries to issue, grant, extend or enter into any
          such security, option, warrant, call, right,
          commitment, agreement, arrangement or undertaking.  As
          of the date of this Agreement, there are no outstanding
          contractual obligations of Parent or any of its
          subsidiaries to repurchase, redeem or otherwise acquire


                             Page 37 of 90

                                                               30

          any shares of capital stock of Parent or any of its
          subsidiaries.  As of the date of this Agreement, the
          authorized capital stock of Sub consists of 100 shares
          of common stock, par value $1.00 per share, all of
          which have been validly issued, are fully paid and
          nonassessable and are owned by Parent free and clear of
          any Lien.

               (c)  Authority; Noncontravention.  Parent and Sub
          have all requisite corporate power and authority to
          enter into this Agreement and, subject to the Parent
          Stockholder Approval with respect to the issuance of
          Parent Common Stock in the Merger and the Stock Plan
          Amendment, to consummate the transactions contemplated
          by this Agreement.  The execution and delivery of this
          Agreement by Parent and Sub and the consummation by
          Parent and Sub of the transactions contemplated by this
          Agreement have been duly authorized by all necessary
          corporate action on the part of Parent and Sub,
          subject, in the case of the issuance of Parent Common
          Stock in the Merger and the Stock Plan Amendment, to
          the Parent Stockholder Approval.  This Agreement has
          been duly executed and delivered by Parent and Sub and
          constitutes a valid and binding obligation of each such
          party, enforceable against such party in accordance
          with its terms.  The execution and delivery of this
          Agreement do not, and the consummation of the
          transactions contemplated by this Agreement and
          compliance with the provisions of this Agreement will
          not, conflict with, or result in any violation of, or
          default (with or without notice or lapse of time, or
          both) under, or give rise to a right of termination,
          cancellation or acceleration of any obligation or loss
          of a material benefit under, or result in the creation
          of any Lien upon any of the properties or assets of
          Parent or any of its subsidiaries under, (i) the
          certificate of incorporation or by-laws of Parent or
          Sub or the comparable charter or organizational
          documents of any other subsidiary of Parent, (ii) any
          loan or credit agreement, note, bond, mortgage,
          indenture, lease or other agreement, instrument,
          permit, concession, franchise or license applicable to
          Parent, Sub or any other subsidiary of Parent or their
          respective properties or assets or (iii) subject to the
          governmental filings and other matters referred to in
          the following sentence, any judgment, order, decree,
          statute, law, ordinance, rule or regulation applicable
          to Parent, Sub or any other subsidiary of Parent or


                             Page 38 of 90

                                                               31

          their respective properties or assets, other than, in
          the case of clause (ii), any such conflicts,
          violations, defaults, rights or Liens that individually
          or in the aggregate would not (x) have a material
          adverse effect on Parent, (y) impair the ability of
          Parent and Sub to perform their respective obligations
          under this Agreement or (z) prevent the consummation of
          any of the transactions contemplated by this Agreement. 
          No consent, approval, order or authorization of, or
          registration, declaration or filing with, any
          Governmental Entity is required by or with respect to
          Parent, Sub or any other subsidiary of Parent in
          connection with the execution and delivery of this
          Agreement or the consummation by Parent or Sub, as the
          case may be, of any of the transactions contemplated by
          this Agreement, except for (1) the filing of a
          premerger notification and report form under the HSR
          Act, (2) the filing with the SEC of the Form S-4, the
          Joint Proxy Statement relating to the Parent
          Stockholder Approval and such reports under
          Section 13(a) of the Exchange Act as may be required in
          connection with this Agreement and the transactions
          contemplated by this Agreement, (3) the filing of the
          Certificate of Merger with the Secretary of State of
          the Commonwealth of Pennsylvania and the State of
          Delaware and appropriate documents with the relevant
          authorities of other states in which Parent is
          qualified to do business, (4) such consents, approvals,
          orders, authorizations, registrations, declarations and
          filings as may be required under the "takeover" or
          "blue sky" laws of various states or the laws of any
          foreign country in which the Company, Parent or any of
          their respective subsidiaries conducts any business or
          owns any property or assets and (5) such other
          consents, approvals, orders, authorizations,
          registrations, declarations and filings as would not
          individually or in the aggregate (A) have a material
          adverse effect on Parent, (B) impair the ability of
          Parent and Sub to perform their respective obligations
          under this Agreement or (C) prevent the consummation of
          any of the transactions contemplated by this Agreement.

               (d)  SEC Documents; Undisclosed Liabilities. 
          Parent has filed all required reports, schedules,
          forms, statements and other documents with the SEC
          since January 1, 1993 (the "Parent SEC Documents").  As
          of their respective dates, the Parent SEC Documents
          complied in all material respects with the requirements


                             Page 39 of 90 

     <PAGE>40

                                                               32

          of the Securities Act or the Exchange Act, as the case
          may be, and the rules and regulations of the SEC
          promulgated thereunder applicable to such Parent SEC
          Documents, and none of the Parent SEC Documents
          contained any untrue statement of a material fact or
          omitted to state a material fact required to be stated
          therein or necessary in order to make the statements
          therein, in light of the circumstances under which they
          were made, not misleading.  Except to the extent that
          information contained in any Parent SEC Document has
          been revised or superseded by a later Filed Parent SEC
          Document (as defined in Section 3.02(f)), none of the
          Parent SEC Documents contains any untrue statement of a
          material fact or omits to state any material fact
          required to be stated therein or necessary in order to
          make the statements therein, in light of the
          circumstances under which they were made, not
          misleading.  The financial statements of Parent
          included in the Parent SEC Documents comply as to form
          in all material respects with applicable accounting
          requirements and the published rules and regulations of
          the SEC with respect thereto, have been prepared in
          accordance with generally accepted accounting
          principles (except, in the case of unaudited
          statements, as permitted by Form 10-Q of the SEC)
          applied on a consistent basis during the periods
          involved (except as may be indicated in the notes
          thereto) and fairly present the consolidated financial
          position of Parent and its consolidated subsidiaries as
          of the dates thereof and the consolidated results of
          their operations and cash flows (or changes in
          financial position prior to the approval of Financial
          Accounting Standards Board Statement of Financial
          Accounting Standards No. 95) for the periods then ended
          (subject, in the case of unaudited statements, to
          normal year-end audit adjustments).  Other than with
          respect to ERISA and tax matters, which are addressed
          by Sections 3.02(n) and 3.02(o), respectively, except
          as set forth in the Filed Parent SEC Documents, neither
          Parent nor any of its subsidiaries has any liabilities
          or obligations of any nature (whether accrued,
          absolute, contingent or otherwise and whether or not
          required by generally accepted accounting principles to
          be recognized or disclosed on a consolidated balance
          sheet of Parent and its consolidated subsidiaries or in
          the notes thereto) which individually or in the
          aggregate could reasonably be expected to have a
          material adverse effect on Parent.

               (e)  Information Supplied.  None of the
          information supplied or to be supplied by Parent or Sub
          specifically for inclusion or incorporation by
          reference in (i) the Form S-4 will, at the time the
          Form S-4 is filed with the SEC, at any time it is
          amended or supplemented or at the time it becomes
          effective under the Securities Act, contain any untrue
          statement of a material fact or omit to state any
          material fact required to be stated therein or
          necessary to make the statements therein not
          misleading, or (ii) the Joint Proxy Statement will, at
          the date the Joint Proxy Statement is first mailed to
          Parent's stockholders or at the time of the Parent
          Stockholders Meeting (as defined in Section 5.01(b)), 
          contain any untrue statement of a material fact or omit
          to state any material fact required to be stated
          therein or necessary in order to make the statements
          therein, in light of the circumstances under which they
          are made, not misleading.  The Form S-4 will comply as
          to form in all material respects with the requirements
          of the Securities Act and the rules and regulations
          promulgated thereunder and the Joint Proxy Statement
          will comply as to form in all material respects with
          the requirements of the Exchange Act and the rules and
          regulations promulgated thereunder, except that no
          representation or warranty is made by Parent or Sub
          with respect to statements made or incorporated by
          reference in either the Form S-4 or the Joint Proxy
          Statement based on information supplied by the Company
          specifically for inclusion or incorporation by
          reference therein.

               (f)  Absence of Certain Changes or Events.  Except
          as disclosed in the Parent SEC Documents filed and
          publicly available prior to the date of this Agreement
          (the "Filed Parent SEC Documents"), since the date of
          the most recent audited financial statements included
          in the Filed Parent SEC Documents, Parent has conducted
          its business only in the ordinary course, and there has
          not been (i) any material adverse change in Parent,
          (ii) any declaration, setting aside or payment of any
          dividend or distribution (whether in cash, stock or
          property) with respect to any of Parent's capital
          stock, (iii) any split, combination or reclassification
          of any of its capital stock or any issuance or the
          authorization of any issuance of any other securities
          in respect of, in lieu of or in substitution for shares
          of its capital stock, (iv) any damage, destruction or


                             Page 41 of 90 

     <PAGE>42

                                                               34

          loss, whether or not covered by insurance that has or
          could reasonably be expected to have a material adverse
          effect on Parent or (v) any change in accounting
          methods, principles or practices by Parent materially
          affecting its assets, liabilities or business, except
          insofar as may have been disclosed in the Filed Parent
          SEC Documents or required by a change in generally
          accepted accounting principles.

               (g)  Litigation.  Except as disclosed in the Filed
          Parent SEC Documents, there is no suit, action or
          proceeding pending or, to the knowledge of Parent,
          threatened against or affecting Parent or any of its
          subsidiaries (and Parent is not aware of any basis for
          any such suit, action or proceeding) that individually
          or in the aggregate could reasonably be expected to
          (i) have a material adverse effect on Parent,
          (ii) impair the ability of Parent and Sub to perform
          their obligations under this Agreement or (iii) prevent
          the consummation of any of the transactions
          contemplated by this Agreement, nor is there any
          judgment, decree, injunction, rule or order of any
          Governmental Entity or arbitrator outstanding against
          Parent or any of its subsidiaries having, or which is
          reasonably likely to have, any effect referred to in
          clause (i), (ii) or (iii) above.

               (h)  Voting Requirements.  The affirmative vote of
          the holders of a majority of the shares of Parent
          Common Stock present, or represented, and entitled to
          vote thereon at the Parent Stockholders Meeting with
          respect to each of (i) the issuance of shares of Parent
          Common Stock in the Merger and (ii) the Stock Plan
          Amendment are the only votes of the holders of any
          class or series of Parent's capital stock necessary to
          approve this Agreement and the transactions
          contemplated by this Agreement.

               (i)  Labor Matters.  There are no collective
          bargaining or other labor union agreements to which
          Parent or any of its subsidiaries is a party or by
          which any of them is bound.  To the best knowledge of
          Parent, since January 1, 1993, neither Parent nor any
          of its subsidiaries has encountered any labor union
          organizing activity, or had any actual or threatened
          employee strikes, work stoppages, slowdowns or
          lockouts.

               (j)  Brokers.  No broker, investment banker,
          financial advisor or other person, other than Goldman,
          Sachs & Co., the fees and expenses of which will be
          paid by Parent, is entitled to any broker's, finder's,
          financial advisor's or other similar fee or commission
          in connection with the transactions contemplated by
          this Agreement based upon arrangements made by or on
          behalf of Parent or Sub.

               (k)  Opinion of Financial Advisor.  Parent has
          received the oral opinion of Goldman, Sachs & Co. to
          the effect that, based upon and subject to assumptions
          made by Goldman, Sachs & Co. in rendering such opinion
          and based upon such other matters as they consider
          relevant, as of the date of this Agreement, the
          Exchange Ratio is fair to Parent.

               (l)  [Intentionally omitted]

               (m)  Interim Operations of Sub.  Sub was formed
          solely for the purpose of engaging in the transactions
          contemplated hereby, has engaged in no other business
          activities and has conducted its operations only as
          contemplated hereby.

               (n)  Benefit Plans.  Parent and its subsidiaries
          are in compliance in all material respects with the
          applicable provisions of ERISA and the Code with
          respect to each material "employee benefit plan" (as
          defined in Section 3(3) of ERISA) maintained,
          contributed to or required to be maintained or
          contributed to by Parent or its subsidiaries for the
          benefit of any present officers, employees or directors
          of Parent or any of its subsidiaries in the United
          States.

               (o)  Taxes.  (i)  Each of Parent and its
          subsidiaries has filed all tax returns and reports
          required to be filed by it or requests for extensions
          to file such returns or reports have been timely filed,
          granted and have not expired, except to the extent that
          such failures to file or to have extensions granted
          that remain in effect individually or in the aggregate
          would not have a material adverse effect on Parent. 
          All returns filed by Parent and each of its
          subsidiaries are complete and accurate in all material
          respects to the knowledge of Parent.  Parent and each
          of its subsidiaries has paid (or Parent has paid on its


                             Page 43 of 90 

     <PAGE>44

                                                               36

          behalf) all taxes shown as due on such returns, and the
          most recent financial statements contained in the Filed
          Parent SEC Documents reflect an adequate reserve for
          all taxes payable by Parent and its subsidiaries for
          all taxable periods and portions thereof accrued
          through the date of such financial statements.

              (ii)  No deficiencies for any taxes have been
          proposed, asserted or assessed against Parent or any of
          its subsidiaries that are not adequately reserved for,
          except for deficiencies that individually or in the
          aggregate would not have a material adverse effect on
          Parent, and no requests for waivers of the time to
          assess any such taxes have been granted or are pending. 
          The Federal income tax returns of Parent and each of
          its subsidiaries consolidated in such returns have been
          examined by and settled with the United States Internal
          Revenue Service for all years through 1990.  The
          statute of limitations on assessment or collection of
          any taxes due from Parent or any of its subsidiaries
          has expired for all taxable years of Parent or such
          subsidiaries through 1990.

              (iii)  Neither Parent nor any of its subsidiaries
          has taken any action or has any knowledge of any fact
          or circumstance that is reasonably likely to prevent
          the transactions contemplated hereby, including the
          Merger, from qualifying as a reorganization within the
          meaning of Section 368(a) of the Code.

               (p)  Rights Agreement.  The execution and delivery
          of this Agreement by Parent and Sub and consummation of
          the Merger and other transactions contemplated hereby
          will not result in the grant or distribution of any
          Rights to any person under the Rights Agreement (except
          for the Rights attached to the Parent Common Stock
          issuable in the Merger or pursuant to this Agreement)
          or enable or require any Rights to be exercised or
          triggered.

               (q)  Compliance with Applicable Laws.  (i)  Each
          of Parent and its subsidiaries has in effect all
          Permits necessary for it to own, lease or operate its
          properties and assets and to carry on its business as
          now conducted, and there has occurred no default under
          any such Permit, except for the lack of Permits and for
          defaults under Permits which lack or default
          individually or in the aggregate would not have a


                             Page 44 of 90 

     <PAGE>45

                                                               37

          material adverse effect on Parent.  Except as disclosed
          in the Filed Parent SEC Documents, Parent and its
          subsidiaries are in compliance with all applicable
          statutes, laws, ordinances, rules, orders and
          regulations of any Governmental Entity, except for
          possible noncompliance which individually or in the
          aggregate would not have a material adverse effect on
          Parent.

               (ii)  Each of Parent and its subsidiaries is, and
          has been, in compliance with all applicable
          Environmental Laws, except for possible noncompliance
          which individually or in the aggregate would not have a
          material adverse effect on Parent.

               (r)  Contracts; Debt Instruments.  Except as
          disclosed in the Filed Parent SEC Documents or on the
          Parent Disclosure Schedule, there are no contracts or
          agreements that are material to the business,
          properties, assets, condition (financial or otherwise),
          results of operations or prospects of Parent and its
          subsidiaries taken as a whole.  Neither Parent nor any
          of its subsidiaries is in violation of or in default
          under (nor does there exist any condition which upon
          the passage of time or the giving of notice would cause
          such a violation of or default under) any loan or
          credit agreement, note, bond, mortgage, indenture,
          lease, permit, concession, franchise, license or any
          other contract, agreement, arrangement or understanding
          to which it is a party or by which it or any of its
          properties or assets is bound, except for violations or
          defaults that individually or in the aggregate would
          not have a material adverse effect on Parent.

               (s)  Title to Properties.  (i)  Each of Parent and
          each of its subsidiaries has good and marketable title
          to, or valid leasehold interests in, all its material
          properties and assets except for such as are no longer
          used or useful in the conduct of its businesses or as
          have been disposed of in the ordinary course of
          business and except for defects in title, easements,
          restrictive covenants and similar encumbrances or
          impediments that individually or in the aggregate would
          not materially interfere with its ability to conduct
          its business as currently conducted.  All such material
          properties and assets, other than properties and assets
          in which Parent or any of its subsidiaries has
          leasehold interests, are free and clear of all Liens,


                             Page 45 of 90 

     <PAGE>46

                                                               38

          except for Liens that individually or in the aggregate
          would not materially interfere with the ability of
          Parent and its subsidiaries to conduct business as
          current conducted.

              (ii)  Each of Parent and each of its subsidiaries
          has complied in all material respects with the terms of
          all material leases to which it is a party and under
          which it is in occupancy, and all such leases are in
          full force and effect.  Each of Parent and each of its
          subsidiaries enjoys peaceful and undisturbed possession
          under all such material leases.

               (t)  Intellectual Property.  Parent and its
          subsidiaries own, or are validly licensed or otherwise
          have the right to use, all Intellectual Property Rights
          which are material to the conduct of the business of
          Parent and its subsidiaries taken as a whole.  The
          Parent Disclosure Schedule sets forth a description of
          all Intellectual Property Rights which are material to
          the conduct of the business of Parent and its
          subsidiaries taken as a whole.  Except as set forth on
          the Parent Disclosure Schedule, no claims are pending
          or, to the knowledge of Parent, threatened that Parent
          or any of its subsidiaries is infringing or otherwise
          adversely affecting the rights of any person with
          regard to any Intellectual Property Right.  To the
          knowledge of Parent, except as set forth on the Parent
          Disclosure Schedule, no person is infringing the rights
          of Parent or any of its subsidiaries with respect to
          any Intellectual Property Right.


                              ARTICLE IV

               Covenants Relating to Conduct of Business

               SECTION 4.01.  Conduct of Business.  (a)  Conduct
     of Business by the Company.  During the period from the date
     of this Agreement to the Effective Time of the Merger, the
     Company shall, and shall cause its subsidiaries to, carry on
     their respective businesses in the usual, regular and
     ordinary course in substantially the same manner as
     heretofore conducted and, to the extent consistent
     therewith, use all reasonable efforts to preserve intact
     their current business organizations, keep available the
     services of their current officers and employees and
     preserve their relationships with customers, suppliers,

                                                               39

     licensors, licensees, distributors and others having
     business dealings with them to the end that their goodwill
     and ongoing businesses shall be unimpaired at the Effective
     Time of the Merger.  Without limiting the generality of the
     foregoing, during the period from the date of this Agreement
     to the Effective Time of the Merger, the Company shall not,
     and shall not permit any of its subsidiaries to:

               (i) (x) declare, set aside or pay any dividends
          on, or make any other distributions in respect of, any
          of its capital stock, other than dividends and
          distributions by a direct or indirect wholly owned
          subsidiary of the Company to its parent, (y) split,
          combine or reclassify any of its capital stock or issue
          or authorize the issuance of any other securities in
          respect of, in lieu of or in substitution for shares of
          its capital stock or (z) purchase, redeem or otherwise
          acquire any shares of capital stock of the Company or
          any of its subsidiaries or any other securities thereof
          or any rights, warrants or options to acquire any such
          shares or other securities;

               (ii) issue, deliver, sell, pledge or otherwise
          encumber any shares of its capital stock, any other
          voting securities or any securities convertible into,
          or any rights, warrants or options to acquire, any such
          shares, voting securities or convertible securities
          (other than (x) the issuance of Company Common Stock
          upon the exercise of Employee Stock Options (as defined
          in Section 5.06) outstanding on the date of this
          Agreement and in accordance with their present terms
          and (y) the issuance of Company Common Stock upon

          thereof in accordance with their present terms);

          or other comparable charter or organizational
          documents;

          consolidating with, or by purchasing a substantial
          portion of the assets of, or by any other manner, any
          business or any corporation, partnership, joint
          venture, association or other business organization or
          division thereof or (y) any assets that individually or
          in the aggregate are material to the Company and its
          subsidiaries taken as a whole, except purchases of

          inventory in the ordinary course of business consistent
          with past practice;

               (v) sell, lease, license, mortgage or otherwise
          encumber or subject to any Lien or otherwise dispose of
          any of its properties or assets, except sales in the
          ordinary course of business consistent with past
          practice of inventory or of furniture, fixtures and
          equipment that are no longer used by or useful to the
          Company or its subsidiaries;

              (vi) (x) incur any indebtedness, except for short-

          of its subsidiaries or between such subsidiaries, or
          (y) make any loans, advances or capital contributions
          to, or investments in, any other person, other than to
          the Company or any direct or indirect wholly owned
          subsidiary of the Company;

              (vii) make or agree to make any new capital
          expenditure or capital expenditures which individually

              (viii) make any tax election that could reasonably be
          expected to have a material adverse effect on the
          Company or settle or compromise any income tax
          liability;

              (ix) pay, discharge, settle or satisfy any claims,
          liabilities or obligations (absolute, accrued, asserted
          or unasserted, contingent or otherwise), other than the
          payment, discharge or satisfaction, in the ordinary
          course of business consistent with past practice or in
          accordance with their terms, of liabilities reflected
          or reserved against in, or contemplated by, the most
          recent consolidated financial statements (or the notes
          thereto) of the Company included in the Filed SEC
          Documents or incurred since the date of such financial
          statements in the ordinary course of business
          consistent with past practice;

               (x) except in the ordinary course of business,
          modify, amend or terminate any material contract or
          agreement to which the Company or any subsidiary is a

                                                               41

          party or waive, release or assign any material rights
          or claims thereunder;

               (xi) take any action that (without giving effect to
          any action taken or agreed to be taken by Parent or any
          of its affiliates) would prevent Parent from treating
          the Merger as a "reorganization" under Section 368(a)
          of the Code; or

               (xii) authorize any of, or commit or agree to take
          any of, the foregoing actions.

               (b)  Conduct of Business by Parent.  During the
     period from the date of this Agreement to the Effective Time
     of the Merger, Parent shall, and shall cause its
     subsidiaries to, carry on their respective businesses in the
     usual, regular and ordinary course in substantially the same
     manner as heretofore conducted and, to the extent consistent
     therewith, use all reasonable efforts to preserve intact
     their current business organizations, keep available the
     services of their current officers and employees and
     preserve their relationships with customers, suppliers,
     licensors, licensees, distributors and others having
     business dealings with them to the end that their goodwill
     and ongoing businesses shall be unimpaired at the Effective
     Time of the Merger; provided that the foregoing shall not
     prevent Parent or any of its subsidiaries from discontinuing
     or disposing of any part of its assets or business if such
     action is, in the judgment of Parent, desirable in the
     conduct of the business of Parent and its subsidiaries or if
     such action would not result in either of the effects
     referred to in clause (ii) below.  Without limiting the
     generality of the foregoing, during the period from the date
     of this Agreement to the Effective Time of the Merger,
     Parent shall not, and shall not permit any of its
     subsidiaries to:

               (i) (x) declare, set aside or pay any dividends
          on, or make any other distributions in respect of, any
          capital stock of Parent or (y) split, combine or
          reclassify any of its capital stock or issue or
          authorize the issuance of any other securities in
          respect of, in lieu of or in substitution for shares of
          Parent's capital stock (other than exchanges in the
          ordinary course under Parent's employee stock plans);

               (ii) take any action that (without giving effect to
          any action taken or agreed to be taken by the Company


                             Page 49 of 90 

     <PAGE>50

                                                               42

          or any of its affiliates) would prevent Parent from
          treating the Merger as a "reorganization" under
          Section 368(a) of the Code; 

                (iii) amend the Rights Agreement in any manner
          adverse to the holders of Company Common Stock;

                (iv) issue, deliver, sell, pledge or otherwise
          encumber any shares of its capital stock, any other
          voting securities or any securities convertible into,
          or any rights, warrants or options to acquire, any such
          shares, voting securities or convertible securities, in
          each case if any such action could reasonably be
          expected to (A) delay materially the date of mailing of
          the Joint Proxy Statement or, (B) if it were to occur
          after such date of mailing, require an amendment of the
          Joint Proxy Statement;

               (v) acquire or agree to acquire (x) by merging or
          consolidating with, or by purchasing a substantial
          portion of the assets of, or by any other manner, any
          business or any corporation, partnership, joint
          venture, association or other business organization or
          division thereof or (y) any assets that individually or
          in the aggregate are material to the Company and its
          subsidiaries taken as a whole, except purchases of
          inventory in the ordinary course of business consistent
          with past practice, in each case if any such action
          could reasonably be expected to (A) delay materially
          the date of mailing of the Joint Proxy Statement or,
          (B) if it were to occur after such date of mailing,
          require an amendment of the Joint Proxy Statement; or

               (vi) authorize any of, or commit or agree to take
          any of, the foregoing actions.

               (c)  Other Actions.  The Company and Parent shall
     not, and shall not permit any of their respective
     subsidiaries to, take any action that would, or that could
     reasonably be expected to, result in (i) any of the
     representations and warranties of such party set forth in
     this Agreement that are qualified as to materiality becoming
     untrue, (ii) any of such representations and warranties that
     are not so qualified becoming untrue in any material respect
     or (iii) except as otherwise permitted by Section 4.02, any
     of the conditions to the Merger set forth in Article VI not
     being satisfied.

               (d)  Advice of Changes.  The Company and Parent
     shall promptly advise the other party orally and in writing
     of any change or event having, or which, insofar as can
     reasonably be foreseen, would have, a material adverse
     effect on such party or on the truth of their respective
     representations and warranties.

               SECTION 4.02.  No Solicitation.  (a)  The Company
     shall not, nor shall it permit any of its subsidiaries to,
     nor shall it authorize or permit any officer, director or
     employee of or any investment banker, attorney or other
     advisor or representative of, the Company or any of its
     subsidiaries to, directly or indirectly, (i) solicit,
     initiate or encourage the submission of, any takeover
     proposal or (ii) participate in any discussions or
     negotiations regarding, or furnish to any person any
     information with respect to, or take any other action to
     facilitate any inquiries or the making of any proposal that
     constitutes, or may reasonably be expected to lead to, any
     takeover proposal; provided, however, that prior to the
     Stockholders Meeting, to the extent required by the
     fiduciary obligations of the Board of Directors of the
     Company, as determined in good faith by the Board of
     Directors based on the advice of outside counsel, the
     Company may, (A) in response to an unsolicited request
     therefor, furnish information with respect to the Company to
     any person pursuant to a customary confidentiality agreement
     (as determined by the Company's outside counsel) and discuss
     such information (but not the terms of any possible takeover
     proposal) with such person and (B) upon receipt by the
     Company of a takeover proposal, following delivery to Parent
     of the notice required pursuant to Section 4.02(c),
     participate in negotiations regarding such takeover
     proposal.  Without limiting the foregoing, it is understood
     that any violation of the restrictions set forth in the
     preceding sentence by any officer, director or employee of
     the Company or any of its subsidiaries or any investment
     banker, attorney or other advisor or representative of the
     Company or any of its subsidiaries, whether or not such
     person is purporting to act on behalf of the Company or any
     of its subsidiaries or otherwise, shall be deemed to be a
     breach of this Section 4.02(a) by the Company.  For purposes
     of this Agreement, "takeover proposal" means any proposal
     for a merger or other business combination involving the
     Company or any of its subsidiaries or any proposal or offer
     to acquire in any manner, directly or indirectly, an equity
     interest in, any voting securities of, or a substantial
     portion of the assets of the Company or any of its

                                                               44

     subsidiaries, other than the transactions contemplated by
     this Agreement.

               (b)  Neither the Board of Directors of the Company
     nor any committee thereof shall (i) withdraw or modify, or
     propose to withdraw or modify, in a manner adverse to Parent
     or Sub, the approval or recommendation by such Board of
     Directors or any such committee of this Agreement or the
     Merger, (ii) approve or recommend, or propose to approve or
     recommend, any takeover proposal or (iii) enter into any
     agreement with respect to any takeover proposal. 
     Notwithstanding the foregoing, in the event the Board of
     Directors of the Company receives a takeover proposal that,
     in the exercise of its fiduciary obligations (as determined
     in good faith by the Board of Directors based on the advice
     of outside counsel), it determines to be a superior
     proposal, the Board of Directors may (subject to the
     following sentences) withdraw or modify its approval or
     recommendation of this Agreement and the Merger, approve or
     recommend any such superior proposal, enter into an
     agreement with respect to such superior proposal or
     terminate this Agreement, in each case at any time after the
     second business day following Parent's receipt of written
     notice (a "Notice of Superior Proposal") advising Parent
     that the Board of Directors has received a superior
     proposal, specifying the material terms and conditions of
     such superior proposal and identifying the person making
     such superior proposal.  In the event the Board of Directors
     of the Company takes any of the foregoing actions with
     respect to such superior proposal, the Company shall,
     concurrently with the taking of any such action, pay to
     Parent the Termination Fee plus all Expenses pursuant to
     Section 5.09(b).  For purposes of this Agreement, "superior
     proposal" means a bona fide takeover proposal to acquire,
     directly or indirectly, for consideration consisting of cash
     and/or securities, more than 50% of the shares of Company
     Common Stock then outstanding or all or substantially all
     the assets of the Company, and otherwise on terms which the
     Board of Directors of the Company determines in its good
     faith reasonable judgment to be more favorable to the
     Company's stockholders than the Merger (based on the written
     opinion, with only customary qualifications, of the
     Company's independent financial advisor that the value of
     the consideration provided for in such proposal is superior
     to the value of the consideration provided for in the
     Merger) and for which financing, to the extent required, is
     then committed or which, in the good faith reasonable

     <PAGE>53

                                                               45

     judgment of the Board of Directors, is reasonably capable of
     being financed by such third party.

               (c)  In addition to the obligations of the Company
     set forth in paragraph (b) above, the Company promptly shall
     advise Parent orally and in writing of any request for
     information or of any takeover proposal or any inquiry with
     respect to or which could lead to any takeover proposal, the
     identity of the person making any such takeover proposal or
     inquiry and the material terms and conditions thereof.  The
     Company will keep Parent generally informed of the status
     and details of any such request, takeover proposal or
     inquiry.

                         Additional Agreements

               SECTION 5.01.  Preparation of Form S-4 and the
     Joint Proxy Statement; Stockholders Meetings.  (a)  As soon
     as practicable following the date of this Agreement, the
     Company and Parent shall prepare and file with the SEC the
     Joint Proxy Statement and Parent shall prepare and file with
     the SEC the Form S-4, in which the Joint Proxy Statement
     will be included as a prospectus.  Each of the Company and
     Parent shall use its best efforts to have the Form S-4
     declared effective under the Securities Act as promptly as
     practicable after such filing.  The Company will use its
     best efforts to cause the Joint Proxy Statement to be mailed
     to the Company's stockholders, and Parent will use its best
     efforts to cause the Joint Proxy Statement to be mailed to
     Parent's stockholders, in each case as promptly as
     practicable after the Form S-4 is declared effective under
     the Securities Act.  Parent shall also take any action
     (other than qualifying to do business in any jurisdiction in
     which it is not now so qualified) required to be taken under
     any applicable state securities laws in connection with the
     issuance of Parent Common Stock in the Merger and under the
     Stock Plans and the Company shall furnish all information
     concerning the Company and the holders of the Company Common
     Stock and rights to acquire Company Common Stock pursuant to
     the Stock Plans as may be reasonably requested in connection
     with any such action.

               (b)  The Company will, as soon as practicable
     following the date of this Agreement, duly call, give notice
     of, convene and hold a meeting of its stockholders (the


                             Page 53 of 90 

     <PAGE>54

                                                               46

     "Stockholders Meeting") for the purpose of approving the
     Merger.  Parent will, as promptly as practicable following
     the date of this Agreement, duly call, give notice of,
     convene and hold a meeting of its stockholders (the "Parent
     Stockholders Meeting") for the purpose of approving (i) the
     issuance of Parent Common Stock in the Merger and (ii) the
     amendment of the 1992 Option Plan to increase the number of
     shares of Parent Common Stock that are authorized for
     issuance thereunder by 450,000 shares (the "Stock Plan
     Amendment").  The Company and Parent will, through their
     respective Boards of Directors, recommend to their
     respective stockholders approval of the foregoing matters,
     except to the extent that the Board of Directors of the
     Company shall have withdrawn or modified its approval or
     recommendation of this Agreement or the Merger as permitted
     by Section 4.02(b).  Without limiting the generality of the
     foregoing, the Company agrees that its obligations pursuant
     to the first sentence of this Section 5.01(b) shall not be
     affected by (i) the commencement, public proposal, public
     disclosure or communication to the Company of any takeover
     proposal or (ii) the withdrawal or modification by the Board
     of Directors of the Company of its approval or
     recommendation of this Agreement or the Merger.  Parent and
     the Company will use reasonable efforts to hold the
     Stockholders Meeting and the Parent Stockholders Meeting on
     the same day and use their best efforts to hold such
     Meetings as soon as practicable after the date hereof. 

               (c)  The Company shall use its best efforts to
     obtain the opinion of Merrill Lynch, dated on or about the
     date that is two business days prior to the mailing of the
     Joint Proxy Statement, to the effect that, as of such date,
     the Exchange Ratio is fair to the Company's stockholders
     from a financial point of view, and shall cause a signed
     copy of such opinion to be delivered to Parent.

               (d)  Parent shall use its best efforts to obtain
     the opinion of Goldman, Sachs & Co., dated on or about the
     date that is two business days prior to the mailing of the
     Joint Proxy Statement, to the effect that, as of such date,
     the Exchange Ratio is fair to Parent, and shall cause a
     signed copy of such opinion to be delivered to the Company.

               SECTION 5.02.  Letter of the Company's
     Accountants.  The Company shall use its best efforts to
     cause to be delivered to Parent a letter of KPMG Peat
     Marwick, the Company's independent public accountants, dated
     a date within two business days before the date on which the


                             Page 54 of 90 

     <PAGE>55

                                                               47

     Form S-4 shall become effective and a letter of KPMG Peat
     Marwick, dated a date within two business days before the
     Closing Date, each addressed to Parent, in form and
     substance reasonably satisfactory to Parent and customary in
     scope and substance for letters delivered by independent
     public accountants in connection with registration
     statements similar to the Form S-4.

               SECTION 5.03.  Letter of Parent's Accountants. 
     Parent shall use its best efforts to cause to be delivered
     to the Company a letter of KPMG Peat Marwick, Parent's
     independent public accountants, dated a date within two
     business days before the date on which the Form S-4 shall
     become effective and a letter of KPMG Peat Marwick, dated a
     date within two business days before the Closing Date, each
     addressed to the Company, in form and substance reasonably
     satisfactory to the Company and customary in scope and
     substance for letters delivered by independent public
     accountants in connection with registration statements
     similar to the Form S-4.

               SECTION 5.04.  Access to Information;
     Confidentiality.  (a)  Each of the Company and Parent shall,
     and shall cause each of its respective subsidiaries to,
     afford to the other party and to the officers, employees,
     accountants, counsel, financial advisors and other
     representatives of such other party, reasonable access
     during normal business hours during the period prior to the
     Effective Time of the Merger to all their respective
     properties, books, contracts, commitments, personnel and
     records and, during such period, each of the Company and
     Parent shall, and shall cause each of its respective
     subsidiaries to, furnish promptly to the other party (a) a
     copy of each report, schedule, registration statement and
     other document filed by it during such period pursuant to
     the requirements of Federal or state securities laws and
     (b) all other information concerning its business,
     properties and personnel as such other party may reasonably
     request.  Except as required by law, each of the Company and
     Parent will hold, and will cause its respective officers,
     employees, accountants, counsel, financial advisors and
     other representatives and affiliates to hold, any nonpublic
     information in confidence until such time as such
     information becomes publicly available (otherwise than
     through the wrongful act of any such person) and shall use
     its best efforts to ensure that such persons do not disclose
     such information to others without the prior written consent
     of the Company or Parent, as the case may be.  In the event


                             Page 55 of 90 

     <PAGE>56

                                                               48

     of the termination of this Agreement for any reason, the
     Company and Parent shall promptly return or destroy all
     documents containing nonpublic information so obtained from
     the other party or any of its subsidiaries and any copies
     made of such documents.  In addition, Parent and the Company
     shall not, and shall cause their respective advisors and
     agents not to, use any such nonpublic information for any
     purpose except in furtherance of the transactions
     contemplated by this Agreement.

               (b)  Neither Parent nor any of its subsidiaries
     will solicit or employ any employees of the Company or any
     of its subsidiaries as long as they are employed by the
     Company or such subsidiary during the period prior to the
     Effective Time of the Merger (except as contemplated by this
     Agreement) and, in the event of termination of this
     Agreement for any reason, for a period of two years after
     the date of termination.

               SECTION 5.05.  Best Efforts; Notification. 
     (a)  Upon the terms and subject to the conditions set forth
     in this Agreement, unless, to the extent permitted by
     Section 4.02(b), the Board of Directors of the Company
     approves or recommends a superior proposal, each of the
     parties agrees to use its best efforts to take, or cause to
     be taken, all actions, and to do, or cause to be done, and
     to assist and cooperate with the other parties in doing, all
     things necessary, proper or advisable to consummate and make
     effective, in the most expeditious manner practicable, the
     Merger and the other transactions contemplated by this
     Agreement, including (i) the obtaining of all necessary
     actions or nonactions, waivers, consents and approvals from
     Governmental Entities and the making of all necessary
     registrations and filings (including filings with
     Governmental Entities, if any) and the taking of all
     reasonable steps as may be necessary to obtain an approval
     or waiver from, or to avoid an action or proceeding by, any
     Governmental Entity, (ii) the obtaining of all necessary
     consents, approvals or waivers from third parties and
     (iii) the execution and delivery of any additional
     instruments necessary to consummate the transactions
     contemplated by, and to fully carry out the purposes of,
     this Agreement.  In connection with and without limiting the
     foregoing, the Company and its Board of Directors shall
     (A) take all action necessary to ensure that no state
     takeover statute or similar statute or regulation is or
     becomes applicable to the Merger, this Agreement or any of
     the other transactions contemplated by this Agreement and


                             Page 56 of 90 

     <PAGE>57

                                                               49

     (B) if any state takeover statute or similar statute or
     regulation becomes applicable to the Merger, this Agreement
     or any other transaction contemplated by this Agreement,
     take all action necessary to ensure that the Merger and the
     other transactions contemplated by this Agreement may be
     consummated as promptly as practicable on the terms
     contemplated by this Agreement and otherwise to minimize the
     effect of such statute or regulation on the Merger and the
     other transactions contemplated by this Agreement. 
     Notwithstanding the foregoing, the Board of Directors of the
     Company shall not be prohibited from taking any action
     permitted by Section 4.02(b).

               (b)  The Company shall give prompt notice to
     Parent, and Parent or Sub shall give prompt notice to the
     Company, of (i) any representation or warranty made by it
     contained in this Agreement that is qualified as to
     materiality becoming untrue or inaccurate in any respect or
     any such representation or warranty that is not so qualified
     becoming untrue or inaccurate in any material respect or
     (ii) the failure by it to comply with or satisfy in any
     material respect any covenant, condition or agreement to be
     complied with or satisfied by it under this Agreement;
     provided, however, that no such notification shall affect
     the representations, warranties, covenants or agreements of
     the parties or the conditions to the obligations of the
     parties under this Agreement.

               SECTION 5.06.  Stock Options.  (a)  As soon as
     practicable following the date of this Agreement, the Board
     of Directors of the Company (or, if appropriate, any
     committee administering the Stock Plans) shall adopt such
     resolutions or take such other actions as may be required to
     effect the following:

               (i) adjust the terms of all outstanding employee
          stock options to purchase shares of Company Common
          Stock ("Employee Stock Options") granted under the
          Company's 1982 Incentive Stock Option Plan, the 1985
          Incentive Stock Option Plan, the 1986 Non-Qualified
          Stock Option Plan, the 1988 Non-Qualified Stock Option
          Plan and the 1991 Non-Qualified Stock Option Plan and
          any other stock option plan, program or arrangement of
          the Company (collectively, the "Stock Plans"), whether
          vested or unvested, as necessary to provide that, at
          the Effective Time of the Merger, each Employee Stock
          Option outstanding immediately prior to the Effective
          Time of the Merger shall be deemed to constitute an


                             Page 57 of 90 

     <PAGE>58

                                                               50

          option to acquire, on the same terms and conditions as
          were applicable under such Employee Stock Option,
          including vesting, the same number of shares of Parent
          Common Stock as the holder of such Employee Stock
          Option would have been entitled to receive pursuant to
          the Merger had such holder exercised such Employee
          Stock Option in full immediately prior to the Effective
          Time of the Merger, at a price per share equal to
          (A) the aggregate exercise price for the shares of
          Company Common Stock otherwise purchasable pursuant to
          such Employee Stock option divided by (B) the aggregate
          number of shares of Parent Common Stock deemed
          purchasable pursuant to such Employee Stock Option
          (each, as so adjusted, an "Adjusted Option"); provided,
          however, that in the case of any option to which
          Section 421 of the Code applies by reason of its
          qualification under any of Sections 422 through 424 of
          the Code ("qualified stock options"), the option price,
          the number of shares purchasable pursuant to such
          option and the terms and conditions of exercise of such
          option shall be determined in order to comply with
          Section 424 of the Code; and

                (ii) make such other changes to the Stock Plans as
          it deems appropriate to give effect to the Merger
          (subject to the approval of Parent, which shall not be
          unreasonably withheld).

               (b)  As soon as practicable after the Effective
     Time of the Merger, Parent shall deliver to the holders of
     Employee Stock Options appropriate notices setting forth
     such holders' rights pursuant to the respective Stock Plans
     and the agreements evidencing the grants of such Employee
     Stock Options shall continue in effect on the same terms and
     conditions (subject to the adjustments required by this
     Section 5.06 after giving effect to the Merger).  Parent
     shall comply with the terms of the Stock Plans and ensure,
     to the extent required by, and subject to the provisions of,
     such Stock Plans, that the Employee Stock Options which
     qualified as qualified stock options prior to the Effective
     Time of the Merger continue to qualify as qualified stock
     options after the Effective Time of the Merger.

               (c)  Parent agrees to use reasonable efforts to
     take such actions as are necessary for the conversion of the
     Employee Stock Options of the Company pursuant to
     Section 5.06(a), including the reservation, issuance and



                             Page 58 of 90 

     <PAGE>59

                                                               51

     listing of Common Stock of Parent as is necessary to
     effectuate the transactions contemplated by Section 5.06(a).

               (d)  A holder of an Adjusted Option may exercise
     such Adjusted Option in whole or in part in accordance with
     its terms by delivering a properly executed notice of
     exercise to Parent, together with the consideration therefor
     and the Federal withholding tax information, if any,
     required in accordance with the related Stock Plan.

               SECTION 5.07.  Benefit Plans.  (a)  Except as
     provided in Section 5.06 and subject to the provisions of
     ERISA and the Code, Parent agrees to cause the Surviving
     Corporation to maintain for a period of at least two years
     after the Effective Time of the Merger the Benefit Plans of
     the Company and its subsidiaries in effect on the date of
     this Agreement or to provide benefits to employees of the
     Company and its subsidiaries that are comparable in the
     aggregate to those in effect on the date of this Agreement,
     and thereafter Parent will cause the employees of the
     Surviving Corporation to have benefit plans that are at
     least comparable to those provided to the employees of
     Parent.  Parent will cause each employee benefit plan of the
     Surviving Corporation or Parent covering such employees of
     the Company and its subsidiaries to recognize the service of
     such employees with the Company and its subsidiaries prior
     to the Closing Date, but only for purposes of eligibility to
     participate and vesting under any such plan.

               (b)  After the Effective Time of the Merger,
     Parent intends to grant to key employees of the Surviving
     Corporation options to purchase Parent Common Stock and
     restricted stock awards commensurate with those granted to
     key employees of Parent.

               SECTION 5.08.  Indemnification and Insurance. 
     (a)  Parent and Sub agree that all rights to indemnification
     for acts or omissions occurring at or prior to the Effective
     Time of the Merger now existing in favor of the current or
     former directors or officers of the Company and its
     subsidiaries as provided in their respective certificates of
     incorporation or by-laws shall survive the Merger and shall
     continue in full force and effect in accordance with their
     terms for a period of not less than six years from the
     Effective Time of the Merger.  Parent will cause to be
     maintained for a period of not less than five years from the
     Effective Time of the Merger the Company's current
     directors' and officers' insurance and indemnification

     policy to the extent that it provides coverage for events
     occurring prior to the Effective Time of the Merger (the
     "D&O Insurance") for all persons who are directors and
     officers of the Company on the date of this Agreement, so
     long as the annual premium therefor would not be in excess
     of 150% of the last annual premium paid prior to the date of
     this Agreement (the "Maximum Premium"); provided, however,
     that Parent may, in lieu of maintaining such existing D&O
     Insurance as provided above, cause comparable coverage to be
     provided under any policy maintained for the benefit of
     Parent or any of its subsidiaries, so long as the material
     terms thereof are no less advantageous that the existing D&O
     Insurance.  If the existing D&O Insurance expires, is
     terminated or cancelled during such five-year period, Parent
     will use all reasonable efforts to cause to be obtained as
     much D&O Insurance as can be obtained for the remainder of
     such period for an annualized premium not in excess of the
     Maximum Premium, on terms and conditions no less
     advantageous than the existing D&O Insurance.  The Company
     represents to Parent that the Maximum Premium is $72,500.

               (b)  In the event Parent, the Surviving
     Corporation or any of their successors or assigns
     (i) consolidates with or merges into any other person and
     shall not be the continuing or surviving corporation or
     entity of such consolidation or merger or (ii) transfers all
     or substantially all of its properties and assets to any
     person, then and in each such case, proper provisions shall
     be made so that the successors and assigns of Parent or the
     Surviving Corporation, as the case may be, shall assume the
     obligations set forth in this Section 5.08.

               (c)  This Section 5.08 shall survive the
     consummation of the Merger at the Effective Time of the
     Merger, is intended to benefit the Company, Parent, the
     Surviving Corporation and the persons indemnified pursuant
     to Section 5.08(a), and shall be binding on all successors
     and assigns of Parent and the Surviving Corporation.

               SECTION 5.09.  Fees and Expenses.  (a)  Except as
     provided below in this Section 5.09, all fees and expenses
     incurred in connection with the Merger, this Agreement and
     the transactions contemplated by this Agreement shall be
     paid by the party incurring such fees or expenses, whether
     or not the Merger is consummated, except that expenses
     incurred in connection with printing and mailing the Joint
     Proxy Statement and the Form S-4 shall be shared equally by
     Parent and the Company.

     fee of $1,000,000 (the "Termination Fee"), payable in same
     day funds, plus all Expenses not exceeding $500,000 (as
     defined below), if a takeover proposal is commenced,

     withdraws or modifies its approval or recommendation of this
     Agreement or the Merger, approves or recommends such other
     takeover proposal, enters into an agreement with respect to

     this Agreement by Parent or Sub (which breach shall not have
     been cured within five business days following Parent's
     receipt of written notice of such breach from the Company)),
     (ii) the requisite approval of the Company's stockholders
     for the Merger is not obtained at the Stockholders Meeting

     will consult with each other before issuing, and provide
     each other the opportunity to review, comment upon and
     concur with, any press release or other public statements
     with respect to the transactions contemplated by this
     Agreement, including the Merger, and shall not issue any
     such press release or make any such public statement prior
     to such consultation, except as may be required by
     applicable law, court process or by obligations pursuant to
     any listing agreement with any national market system.  The
     parties agree that the initial press release to be issued
     with respect to the transactions contemplated by this
     Agreement is set forth in Exhibit A to this Agreement.

     Stockholders.  (a)  Prior to the Closing Date, the Company
     shall deliver to Parent a letter identifying all persons who

     None of the Company, Parent and Sub may rely on the failure
     of any condition set forth in Section 6.01, 6.02 or 6.03, as

     by such party's failure to act in good faith or to use its
     best efforts to consummate the Merger and the other
     transactions contemplated by this Agreement, as required by
     Section 5.05.


                              ARTICLE VII

          the Company;

               (b) by either Parent or the Company:

                  (i) if, upon a vote at a duly held Stockholders
               Meeting or Parent Stockholders Meeting or any
               adjournment thereof, any required approval of the
               stockholders of the Company or Parent, as the case
               may be, shall not have been obtained;

                 (ii) if the Merger shall not have been
               consummated on or before the date 180 calendar
               days following the date of this Agreement, unless
               the failure to consummate the Merger is the result
               of a willful and material breach of this Agreement
               by the party seeking to terminate this Agreement;
               provided, however, that the passage of such period
               shall be tolled for any part thereof (but not
               exceeding 60 calendar days in the aggregate)
               during which any party shall be subject to a
               nonfinal order, decree, ruling or action
               restraining, enjoining or otherwise prohibiting
               the consummation of the Merger or the calling or

                  (iii) if any Governmental Entity shall have
               issued an order, decree or ruling or taken any
               other action permanently enjoining, restraining or
               otherwise prohibiting the Merger and such order,
               decree, ruling or other action shall have become
               final and nonappealable; or

                   (iv) in the event of a breach by the other party
               of any representation, warranty, covenant or other
               agreement contained in this Agreement which
               (A) would give rise to the failure of a condition
               set forth in Section 6.02(a) or (b) or
               Section 6.03(a) or (b), as applicable, and

               Breach") (provided that the terminating party is
               not then in Material Breach of any representation,
               warranty, covenant or other agreement contained in
               this Agreement);

               (c) by the Company in accordance with the
          provisions of Section 4.02(b); or

               (d) by Parent on February 28, 1994, if on or prior
          to such date (i) the Company shall not have caused a
          representation agreement in the form of Exhibit G
          hereto to be executed and delivered by the Company and
          each of the persons named in Schedule I thereto or
          (ii) the Company shall not have caused an amendment to
          the Convertible Notes and the Note Purchase Agreement
          dated as of May 31, 1989, among the Company and the
          holders of the Convertible Notes, in generally the form
          of Exhibit H hereto to be executed and delivered by the
          Company and those holders of the Convertible Notes
          necessary for such amendment to be effective against
          all holders (other than as a result of the failure by
          Parent to execute and deliver a guarantee in
          substantially the form of an exhibit to the form of
          amendment attached as Exhibit H hereto).

               SECTION 7.02.  Effect of Termination.  In the
     event of termination of this Agreement by either the Company
     or Parent as provided in Section 7.01, this Agreement shall

     Section 5.09, this Section 7.02 and Article VIII and except
     to the extent that such termination results from the willful
     and material breach by a party of any of its
     representations, warranties, covenants or agreements set
     forth in this Agreement.

               SECTION 7.03.  Amendment.  This Agreement may be
     amended by the parties at any time before or after any
     required approval of matters presented in connection with
     the Merger by the stockholders of the Company and at any
     time before or after any required approval of matters
     presented in connection with the issuance of shares of
     Parent Common Stock in the Merger and the Stock Plan
     Amendment by the stockholders of Parent; provided, however,
     that after any such approval, there shall be made no
     amendment that by law requires further approval by such
     stockholders without the further approval of such
     stockholders.  This Agreement may not be amended except by
     an instrument in writing signed on behalf of each of the
     parties.

               SECTION 7.04.  Extension; Waiver.  At any time
     prior to the Effective Time of the Merger, the parties may
     (a) extend the time for the performance of any of the
     obligations or other acts of the other parties, (b) waive
     any inaccuracies in the representations and warranties of
     the other parties contained in this Agreement or in any
     document delivered pursuant to this Agreement or (c) subject
     to the proviso of Section 7.03, waive compliance by the
     other parties with any of the agreements or conditions
     contained in this Agreement.  Any agreement on the part of a
     party to any such extension or waiver shall be valid only if
     set forth in an instrument in writing signed on behalf of
     such party.  The failure of any party to this Agreement to
     assert any of its rights under this Agreement or otherwise
     shall not constitute a waiver of such rights.

               SECTION 7.05.  Procedure for Termination,
     Amendment, Extension or Waiver.  A termination of this
     Agreement pursuant to Section 7.01, an amendment of this
     Agreement pursuant to Section 7.03 or an extension or waiver
     pursuant to Section 7.04 shall, in order to be effective,
     require in the case of Parent, Sub or the Company, action by
     its Board of Directors or the duly authorized designee of
     its Board of Directors.

                                                   CONFORMED COPY


                    AGREEMENT dated as of February 10, 1994,
                  among ADVANCED TECHNOLOGY LABORATORIES, INC., a
                  Delaware corporation ("Parent"), ATL SUB
                  ACQUISITION CORP., a Delaware corporation
                  ("Sub"), and INTERSPEC, INC., a Pennsylvania
                  corporation (the "Company").


               WHEREAS Parent, Sub and the Company have entered
     into an Agreement and Plan of Merger dated as of the date
     hereof (the "Merger Agreement"; capitalized terms used but
     not defined herein having the meanings assigned thereto in
     the Merger Agreement), providing for the merger of the
     Company and Sub (the "Merger"), whereby each issued and
     outstanding share of common stock, par value $.001 per
     share, of the Company ("Company Common Stock"), other than
     shares owned directly or indirectly by Parent or the Company
     and Dissenting Shares (as defined in the Merger Agreement),
     will be converted into the right to receive 0.3835 of a
     share of common stock, par value $.01 per share, of Parent
     ("Parent Common Stock"); and

               WHEREAS, the parties hereto wish to agree to
     execute an amended and restated Merger Agreement as
     described herein in the event that, for accounting purposes,
     the Merger may be accounted for as a "pooling of interests"
     and to make certain other representations and agreements as
     set forth herein;


               NOW, THEREFORE, the parties agree as follows:

               1.  Pooling Approval.  If, by no later than
     February 28, 1994, the Securities and Exchange Commission
     (the "SEC") shall have indicated that it will not object to
     the accounting treatment of the Merger by Parent as, and
     KPMG Peat Marwick, independent auditors of both Parent and
     the Company, shall have confirmed that the Merger may be
     accounted for by Parent as, a pooling of interests by Parent
     for purposes of its consolidated financial statements under
     generally accepted accounting principles and applicable SEC
     rules and regulations (collectively, the "Pooling
     Approval"), then the parties hereby agree immediately after
     receipt of the Pooling Approval to execute an amended and
     restated Merger Agreement (the "Amended and Restated Merger
     Agreement") (i) adjusting the fraction of a share of Parent
     Common Stock into which each share of Company Common Stock
     will be exchanged pursuant to Section 2.01(c) of the Merger

                             Page 78 of 90

                                                                2

     Agreement to be equal to 0.413 of a share of Parent Common
     Stock (the "Pooling Exchange Ratio") and (ii) adding the
     following representations, covenants and conditions thereto
     reflecting that the Merger shall be accounted for as a
     pooling of interests:

               (A)  replacing Section 3.01(r) with the
          following:  "(r)  Accounting Matters.  Neither the
          Company nor, to its best knowledge, any of its
          affiliates, has taken or agreed to take any action that
          (without giving effect to any action taken or agreed to
          be taken by Parent or any of its affiliates) would
          prevent Parent from accounting for the business
          combination to be effected by the Merger as a pooling
          of interests.";

               (B)  replacing Section 3.02(l) with the
          following:  "(l)  Accounting Matters.  Neither Parent
          nor, to its best knowledge, any of its affiliates has
          taken or agreed to take any action that (without giving
          effect to any action taken or agreed to be taken by the
          Company or any of its affiliates) would prevent Parent
          from accounting for the business combination to be
          effected by the Merger as a pooling of interests.";

               (C)  replacing Section 4.01(a)(xi) with the
          following:  "take any action that (without giving
          effect to any action taken or agreed to be taken by
          Parent or any of its affiliates) would prevent Parent
          from accounting for the business combination to be
          effected by the Merger as a pooling of interests or
          from treating the Merger as a "reorganization" under
          Section 368(a) of the Code;";

               (D)  replacing Section 4.01(b)(ii) with the
          following:  "take any action that (without giving
          effect to any action taken or agreed to be taken by the
          Company or any of its affiliates) would prevent Parent
          from accounting for the business combination to be
          effected by the Merger as a pooling of interests or
          from treating the Merger as a "reorganization" under
          Section 368(a) of the Code;";

               (E)  adding to the end of the first sentence of
          Section 5.11(a) the following:  "and for purposes of
          applicable interpretations regarding the pooling-of-
          interests method of accounting";

     <PAGE>80

                                                                3

               (F)  adding to the end of Section 5.11(a) the
          following:  "If the Merger would otherwise qualify for
          pooling-of-interests accounting treatment, shares of
          Parent Common Stock issued to such affiliates of the
          Company in exchange for shares of Company Common Stock
          shall not be transferable until such time as financial
          results covering at least 30 days of combined
          operations of Parent and the Company have been
          published within the meaning of Section 201.01 of the
          SEC's Codification of Financial Reporting Policies,
          regardless of whether each such affiliate has provided
          the written agreement referred to in this Section 5.11,
          except to the extent permitted by, and in accordance
          with, Accounting Series Release 135 and Staff
          Accounting Bulletins 65 and 76.  Any shares of Company
          Common Stock held by such affiliates shall not be
          transferable, regardless of whether each such affiliate
          has provided the written agreement referred to in this
          Section 5.11, if such transfer, either alone or in the
          aggregate with other transfers by affiliates, would
          preclude Parent's ability to account for the business
          combination to be effected by the Merger as a pooling
          of interests.  The Company shall not register the
          transfer of any certificate representing Company Common
          Stock, unless such transfer is made in compliance with
          the foregoing.  Parent shall not be required to
          maintain the effectiveness of the Form S-4 or any other
          registration statement under the Securities Act for the
          purposes of resale of Parent Common Stock by such
          affiliates and the certificates representing Parent
          Common Stock received by such affiliates in the Merger
          shall bear a customary legend regarding applicable
          Securities Act restrictions and the provisions of this
          Section 5.11."; and

               (G)  replacing Section 6.01(f) with the
          following:  "(f)  Pooling.  Parent and the Company
          shall have received from KPMG Peat Marwick, as
          independent auditors of both Parent and the Company, on
          the date of the Joint Proxy Statement and on the
          Closing Date letters, in each case dated as of such
          respective dates, addressed to Parent and the Company,
          in form and substance reasonably acceptable to Parent
          and the Company and stating that the business
          combination to be effected by the Merger may be
          accounted for as a pooling of interests by Parent for
          purposes of its consolidated financial statements under
          generally accepted accounting principles and applicable

                                                                4

          SEC rules and regulations.  No action shall have been
          taken by any Governmental Entity or any statute, rule,
          regulation or order enacted, promulgated or issued by
          any Governmental Entity, or any proposal made for any
          such action by any Governmental Entity which is
          reasonably likely to be put into effect, that would
          prevent Parent from accounting for the business
          combination to be effected by the Merger as a pooling
          of interests."

               2.  Loss of Pooling Approval.  In the event the
     parties execute and deliver the Amended and Restated Merger
     Agreement and that subsequently an event or action occurs
     that would prevent KPMG Peat Marwick from issuing either of
     its letters required pursuant to Section 6.01(f) of the
     Amended and Restated Merger Agreement to the effect that
     Parent may account for the Merger as a pooling of interests,
     the parties hereby agree promptly after the occurrence of
     such event or action to execute a further amendment to the
     Amended and Restated Merger Agreement that would restore the
     original text of the Merger Agreement prior to the
     effectiveness of the Amended and Restated Merger Agreement.

               3.  Representations and Warranties of the Parties. 
     (a) Each of Parent, Sub and the Company hereby represents
     and warrants as follows:

               (i)  Such person has all requisite power and
          authority to enter into this Agreement and to
          consummate the transactions contemplated hereby.  The
          execution and delivery of this Agreement by such person
          and the consummation by such person of the transactions
          contemplated hereby have been duly authorized by all
          necessary corporate action on the part of such person.

              (ii)  This Agreement has been duly executed and
          delivered by such person and constitutes a valid and
          binding obligation of such person enforceable in
          accordance with its terms.

             (iii)  The execution and delivery of this Agreement
          does not, and the consummation of the transactions
          contemplated hereby and compliance with the terms
          hereof will not, conflict with, or result in any
          violation of, or default (with or without notice or
          lapse of time or both) under any provision of the
          certificate of incorporation or by-laws of such person
          or any trust agreement, loan or credit agreement, note,

                                                                5

          bond, mortgage, indenture, lease or other agreement,
          instrument, permit, concession, franchise, license,
          judgment, order, decree, statute, law, ordinance, rule
          or regulation applicable to such person or to its
          property or assets.

              (iv)  No consent, approval, order or authorization
          of, or registration, declaration or filing with, any
          court, administrative agency or commission or other
          governmental authority or instrumentality, domestic or
          foreign, is required by or with respect to such person
          in connection with the execution and delivery of this
          Agreement or the consummation by such person of the
          transactions contemplated hereby.

               (b)  The Company hereby represents and warrants
          that it has received the oral opinion of Merrill Lynch
          to the effect that, based upon and subject to
          assumptions made by Merrill Lynch in rendering such
          opinion and based upon such other matters as they
          consider relevant, as of the date of this Agreement,
          the Pooling Exchange Ratio is fair to the Company's
          stockholders from a financial point of view.

               (c)  Parent hereby represents and warrants that it
          has received the oral opinion of Goldman, Sachs & Co.
          to the effect that, based upon and subject to
          assumptions made by Goldman, Sachs & Co. in rendering
          such opinion and based upon such other matters as they
          consider relevant, as of the date of this Agreement,
          the Pooling Exchange Ratio is fair to Parent.

               4.  Further Assurances.  Each party agrees to use
     its best efforts to obtain the Pooling Approval.  In
     addition, each party will execute and deliver, or cause to
     be executed and delivered, such additional instruments and
     documents as each other party may reasonably request for the
     purpose of effectively carrying out the transactions
     contemplated by this Agreement.

               5.  Assignment.  Neither this Agreement nor any of
     the rights, interests or obligations hereunder shall be
     assigned by any of the parties without the prior written
     consent of the other parties.  Subject to the preceding
     sentence, this Agreement will be binding upon, inure to the
     benefit of and be enforceable by the parties and their
     respective successors and assigns.

               6.  General Provisions.  (a)  The parties hereto
     acknowledge that damages would be an inadequate remedy for

     specifically enforceable.

               (b)  This Agreement may not be amended except by

     upon any person other than the parties hereto any rights or

     in the Merger Agreement.

               (d)  This Agreement may be executed in one or more
     counterparts, all of which shall be considered one and the
     same agreement, and shall become effective when one or more
     of the counterparts have been signed by each of the parties
     and delivered to the other parties, it being understood that
     all parties need not sign the same counterpart.

               (e)  The headings contained in this Agreement are
     for reference purposes only and shall not affect in any way
     the meaning or interpretation of this Agreement.

     construed in accordance with, the laws of the State of

                             PRESS RELEASE


     For Immediate Release             Contact:  Anne Marie Bugge
                                                 (206) 487-7081  


             ATL REPORTS 1993 RESULTS AND ANNOUNCES PLANS

                      TO ACQUIRE INTERSPEC, INC.

     BOTHELL, Washington, February 10, 1994--ATL (Advanced
     Technology Laboratories, Inc.) reported today financial
     results for the fourth quarter and the full year of 1993. 
     The company also announced that it has entered into a Merger
     Agreement with Interspec, Inc., whereby Interspec would
     become a wholly owned subsidiary of ATL through an exchange
     of 0.3835 shares of ATL stock for each share of Interspec
     stock.  If approved by both companies' shareholders in May,
     the merger would create the world's leading ultrasound
     company with combined revenues of approximately $365
     million, an installed base of over 20,000 systems and a
     product line spanning all major clinical applications.

     "Our strategic intent is to be a worldwide leader in all
     clinical segments of the ultrasound market.  We believe this
     merger will accelerate attainment of this objective," said
     Dennis Fill, ATL Chairman and CEO.  "There is a major
     synergistic value to be obtained by combining our mutual
     strengths.  This agreement will broaden and complement our
     strong, established position in the premium performance
     general imaging markets.  We will immediately expand our
     position in the U.S. cardiology market and obtain an
     excellent base from which to address the growing
     international demand for mid-priced cardiac and internal
     medicine systems."

     "Interspec has achieved a solid and growing position in the
     United States by providing systems of excellent performance
     and value to both the private office and hospital markets
     and is a major contributor in the development of three
     dimensional ultrasound imaging for cardiology applications,"
     Fill said.  "Interspec is also a major developer and
     manufacturer of medical transducers and is a leading
     supplier of transesophageal probes and other high technology
     scanheads through its division Echo Ultrasound."

                                                                2

     "Interspec is very pleased to be part of ATL, an ultrasound
     company already recognized as a worldwide technology and
     market leader," said Edward Ray, Chairman, President and CEO
     of Interspec.  "We pioneered the private office
     echocardiography market with high value products.  That
     demand for high value is a major driving factor in hospital
     markets today.  ATL's distribution strength and reputation
     will help us achieve more rapid market penetration,
     globally."

     The merger is subject to customary conditions, including
     approval by the shareholders of both companies.  The
     exchange ratio of 0.3835 is based on the purchase method of
     accounting used for this transaction.  However, if it is
     determined that the transaction qualifies for pooling of
     interests accounting treatment, the exchange ratio will be
     adjusted to 0.4130 of an ATL share for each share of
     Interspec stock.  Interspec has approximately 6.3 million
     shares outstanding.  The merger agreement provides that
     Edward Ray would continue as President of Interspec
     reporting to Dennis Fill and join the ATL Board of
     Directors.

     ATL and Interspec currently anticipate that the transaction
     will close immediately upon shareholder approval.

     ATL's Fourth Quarter and Full Year 1993 Results

     ATL reported fourth quarter revenues of $82.0 million
     compared with $92.6 million in the same quarter of 1992. 
     Net income was $3.5 million or $0.33 per share compared with
     $5.1 million or $0.45 per share in the fourth quarter of
     1992.  The quarter's results include a pre-tax gain of
     approximately $1.1 million resulting from the sale of a
     company in which ATL held a small, minority interest.

     For the year, ATL reported 1993 revenues of $304.5 million
     compared to revenues of $323.7 million in 1992, a decrease
     of 5.9 percent.  The company reported a net loss for the
     year of $5.1 million or $0.46 per share compared with net
     income of $7.4 million or $0.67 per share in 1992.  The 1993
     results include a $4.3 million pre-tax charge in the third
     quarter or approximately $0.39 per share for the
     restructuring of the company's operations.  This
     restructuring included the reduction of the company's
     worldwide work force by 11 percent.  Excluding the impact of
     this charge, ATL would have reported a net loss of $0.8
     million or $0.08 per share for 1993.  The 1992 results

     <PAGE>87

                                                                3

     included a $5.0 million pre-tax charge for the costs
     associated with the stock distribution of SpeceLabs Medical,
     Inc.

     "The year's financial results reflect primarily the
     difficult U.S. market conditions as customers deferred
     purchases in the face of both pending health care reform
     legislation and dramatic changes unfolding in the U.S.
     health care industry," said Fill.  "Our international
     operations, however, achieved a solid performance, despite
     the impact of a stronger dollar and weakness in some
     European economies.  We are pleased with the savings
     realized by our worldwide cost reduction measures as well as
     the progress of our research and development programs."

     Gross margin in the fourth quarter was 46.0 percent compared
     with 45.7 percent in the fourth quarter of 1992 and
     reflected the benefit of product and service cost reduction
     programs as well as product mix.  For the year, competitive
     pricing pressures in the U.S. market together with lower
     volumes negatively impacted 1993 product gross margins
     resulting in a decline of gross margin to 44.9 percent
     compared with 46.1 percent in 1992.

     Fourth quarter selling, general and administrative (SG&A)
     expenses declined 7.7 percent to $23.3 million compared with
     year ago levels due to the restructuring mentioned
     previously as well as tightened cost controls.  Research and
     development expenses rose 13.5 percent to $11.5 million
     compared with the fourth quarter of 1992.

     For the year, SG&A expenses declined by 3.6 percent to $92.0
     million compared with 1992.  Research and development
     expenses rose 14.4 percent to $43.8 million compared with
     the same period in 1992.

     The company held $59.6 million in cash, short-term
     investments and marketable securities and had no long-term
     debt as of December 1993.  During the year, the company used
     $13.4 million to repurchase 794,000 shares of stock reducing
     shares outstanding to 10.5 million.  The shares purchased
     are being used to service the company's employee benefit
     plans.

     Interspec has current revenues of approximately $60 million. 
     Founded in 1979, the company has over 400 employees and is
     headquartered in Ambler, Pennsylvania.  Echo Ultrasound is
     located in close proximity to State College and Penn State

     University.  Interspec stock is traded on the NASDAQ
     National Market System under the symbol ISPC.

     ATL, with headquarters in Bothell, Washington, is a
     worldwide leader in the development, manufacturer,
     distribution and service of diagnostic medical ultrasound
     systems.  Prior to the third quarter of 1992, ATL and
     SpaceLabs Medical, Inc. (SpaceLabs) were subsidiaries of
     Westmark International Inc.  On June 26, 1992, Westmark
     distributed the stock of SpaceLabs to Westmark's
     shareholders creating two independent public companies.  ATL
     stock is traded on the NASDAQ National Market System under
     the symbol ATLI.
