                               ARTICLE I

     in accordance with the DGCL, Sub shall be merged with and into the

Section 1.2.    Closing; Effective Time.  The closing of the Merger (the

     Delaware, in accordance with the relevant provisions of the DGCL
     (the time of such filing being the "Effective Time") and shall make
     all other filings or recordings required under the DGCL.

Section 1.3.   Effects of the Merger.
    (a) At the Effective Time, (i) the separate existence of Sub shall
        cease and Sub shall be merged with and into the Company (Sub and
        the Company are sometimes referred to herein as the "Constituent
        Corporations" and the Company after the Effective Time is
        sometimes referred to herein as the "Surviving Corporation"),
        (ii) the Certificate of Incorporation of the Company, as in
        effect immediately prior to the Effective Time, shall be amended
        as of the Effective Time so that Article Fourth of such
        Certificate of Incorporation 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 1,000 shares of
        Common Stock, $.01 par value per share" and, as so amended, such
        Certificate of Incorporation shall be the Certificate of






        Incorporation of the Surviving Corporation, and (iii) the Bylaws
        of Sub as in effect immediately prior to the Effective Time
        shall be the Bylaws of the Surviving Corporation.

     (b)  The Merger shall have the effects set forth in the DGCL.

Section 1.4.    Directors and Officers.  The directors of Sub
    immediately prior to the Effective Time and the directors of the
    Company listed in Item 1.4 of the Company Letter (as defined below)
    shall be the directors of the Surviving Corporation until their
    resignation or removal or until their respective successors have
    been elected and qualified.  The officers of the Company immediately
    prior to the Effective Time shall continue as officers of the
    Surviving Corporation until their resignation or removal or until
    their respective successors have been elected and qualified.


                               ARTICLE II

                        CONVERSION OF SECURITIES

Section 2.1.    Conversion of Capital Stock. As of the Effective Time,
    by virtue of the Merger and without any action on the part of the
    holder of any shares of Company Common Stock or capital stock of
    Sub:

    (a) Capital Stock of Sub.  Each issued and outstanding share of the
        capital stock of Sub shall be converted into and become one
        fully paid and nonassessable share of Common Stock, $.01 par
        value per share, of the Surviving Corporation.

    (b) Cancellation of Treasury Stock and Parent-Owned Stock.  Any
        shares of the Company Common Stock owned by the Company or by
        any Subsidiary (as defined in Section 3.2(b)) of the Company and
        each share of Company Common Stock owned by Parent, Sub or any
        other wholly owned Subsidiary of Parent shall be canceled and
        retired and shall cease to exist, and no stock of Parent or
        other consideration shall be delivered in exchange therefor.

    (c) Exchange Ratio for Company Common Stock.  Subject to Section
        2.2, each issued and outstanding share of Company Common Stock
        (other than shares to be canceled in accordance with Section
        2.1(b)) shall be converted into the right to receive seventy-two
        hundredths (.72) (the "Exchange Ratio") of a fully paid and
        nonassessable share of Parent Common Stock. All such shares of
        the Company Common Stock, when so converted, shall no longer be
        outstanding and shall automatically be canceled and retired and
        shall cease to exist, and each holder of a certificate
        representing any such shares 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 the surrender of such certificate in accordance
        with Section 2.2, without interest.







    (d) Company Stock Options.  At the Effective Time, all then
        outstanding options to purchase shares of Company Common Stock
        issued under the Company's 1982 Stock Option Plan and 1993
        Equity Compensation Plan, as amended and restated (collectively,
        the "Company Stock Plans"), not exercised as of the Effective
        Time will be assumed by Parent in accordance with Section 6.13.

Section 2.2.    Exchange of Certificates.  The procedures for exchanging
    outstanding shares of Company Common Stock for Parent Common Stock
    upon consummation of the Merger are as follows:

    (a) Exchange Agent.  As soon as practicable after the Effective
        Time, Parent shall deposit with a bank or trust company
        designated by Parent and reasonably acceptable to the Company
        (the "Exchange Agent"), for the benefit of the holders of shares
        of Company Common Stock, for exchange in accordance with this
        Section 2.2, 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 2.1 in
        exchange for outstanding shares of Company Common Stock, which
        shares of Parent Common Stock shall be deemed to be issued at
        the Effective Time subject to the other provisions of this
        Section 2.2.

    (b) Exchange Procedures.  As soon as reasonably practicable after
        the Effective Time, the Exchange Agent shall mail to each holder
        of record of a certificate or certificates which immediately
        prior to the Effective Time represented outstanding shares of
        Company Common Stock (each a "Company Certificate" and,
        collectively, the "Company Certificates") whose shares were
        converted pursuant to Section 2.1 into the right to receive
        shares of Parent Common Stock (i) a letter of transmittal (which
        shall specify that delivery shall be effected, and risk of loss
        and title to the Company Certificates shall pass, only upon
        delivery of the Company 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 Company Certificates in exchange
        for certificates representing shares of Parent Common Stock.
        Upon surrender of a Company 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 be reasonably
        required by the Exchange Agent or Parent, the holder of such
        Company 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 the
        Company Certificate so surrendered shall forthwith be canceled.
        In the event of a transfer of ownership of Company Common Stock
        that 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 transferee if the Company
        Certificate representing such Company Common Stock is presented
        to the Exchange Agent, accompanied by all documents required to
        evidence and effect such transfer and by evidence that any
        applicable stock transfer taxes have been paid. Until
        surrendered as contemplated by this Section 2.2, each Company
        Certificate shall be deemed at any time after the Effective Time
        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 2.2.  Parent or the Exchange Agent
        shall be entitled to deduct and withhold from the consideration
        otherwise payable pursuant to this Agreement such amounts as
        Parent or the Exchange Agent are required to deduct and withhold
        under the Code, or any provision of state, local or foreign tax
        law, with respect to the making of such payment. To the extent
        that amounts are so withheld by Parent or the Exchange Agent,
        such withheld amounts shall be treated for all purposes of this
        Agreement as having been paid to the person in respect of whom
        such deduction and withholding was made by Parent or the
        Exchange Agent.

    (c) Distributions with Respect to Unexchanged Shares.  No dividends
        or other distributions declared or made after the Effective Time
        with respect to Parent Common Stock with a record date after the
        Effective Time shall be paid to the holder of any unsurrendered
        Company 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 2.2(e), until the holder of record of such Company
        Certificate shall surrender such Company Certificate. Subject to
        the effect of applicable laws, following surrender of any such
        Company Certificate, there shall be paid to the record holder of
        the certificates 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 2.2(e) and the amount of
        dividends or other distributions with a record date after the
        Effective Time previously 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 but prior to surrender and
        a payment date subsequent to 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
        shares of Company Common Stock in accordance with the terms
        hereof, including any cash paid pursuant to Sections 2.2(c) and
        2.2(e), shall be deemed to have been issued in full satisfaction
        of all rights pertaining to such shares of Company Common Stock,
        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.  If, after the Effective Time, Company
        Certificates are presented to the Surviving Corporation for any
        reason, they shall be canceled and exchanged as provided in this
        Section 2.2.

    (e) No Fractional Shares.  No certificate or scrip representing
        fractional shares of Parent Common Stock shall be issued upon
        the surrender for exchange of the Company Certificates, and such
        fractional share interests will not entitle the owner thereof to
        vote or to any rights of a stockholder of Parent.
        Notwithstanding any other provision of this Agreement, each
        holder of shares of Company Common Stock exchanged in connection
        with the Merger who would otherwise have been entitled to
        receive a fraction of a share of Parent Common Stock (after
        taking into account all Company Certificates delivered by such
        holder) shall receive, in lieu thereof, cash (without interest)
        in an amount equal to such fractional part of a share of Parent
        Common Stock multiplied by the average of the last reported sale
        prices of Parent Common Stock on The Nasdaq National Market on
        the ten (10) trading days immediately preceding the Effective
        Time.  Parent shall make available to the Exchange Agent the
        cash necessary for this purpose.

    (f) Termination of Exchange Fund.  Any portion of the Exchange Fund
        which remains undistributed to the stockholders of the Company
        for one year after the Effective Time shall be delivered to
        Parent, upon demand, and any stockholders of the Company who
        have not previously complied with this Section 2.2 shall
        thereafter look only to Parent for payment of their claim for
        Parent Common Stock, cash in lieu of fractional shares of Parent
        Common Stock and dividends or distributions with respect to
        Parent Common Stock.

    (g) No Liability.  Neither Parent nor the Company, nor any of their
        respective directors, officers, employees or agents, shall be
        liable to any holder of shares of Company Common Stock or Parent
        Common Stock, as the case may be, for such shares (or dividends
        or distributions with respect thereto) delivered to a public
        official pursuant to any applicable abandoned property, escheat
        or similar law.

    (h) Adjustment of Exchange Ratio.  In the event of any
        reclassification, stock split or stock dividend with respect to
        Parent Common Stock between the date hereof and the Effective
        Time, appropriate adjustments, if any, shall be made by Parent
        to the Exchange Ratio, and all references to the Exchange Ratio
        in this Agreement shall be deemed to be to the Exchange Ratio as
        so adjusted.

    (i) Further Assurances.  If, at any time after the Effective Time,
        the Surviving Corporation shall consider or be advised that any







        deeds, bills of sale, assignments or assurances or any other
        acts or things are necessary, desirable or proper (i) to vest,
        perfect or confirm, of record or otherwise, in the Surviving
        Corporation its right, title and interest in, to or under any of
        the rights, privileges, powers, franchises, properties or assets
        of either of the Constituent Corporations or (ii) otherwise to
        carry out the purposes of this Agreement, the Surviving
        Corporation and its proper officers and directors or their
        designees shall be authorized to execute and deliver, in the
        name and on behalf of either Constituent Corporation, all such
        deeds, bills of sale, assignments and assurances and to do, in
        the name and on behalf of either Constituent Corporation, all
        such other acts and things as may be necessary, desirable or
        proper to vest, perfect or confirm the Surviving Corporation's
        right, title and interest in, to and under any of the rights,
        privileges, powers, franchises, properties or assets of such
        Constituent Corporation and otherwise to carry out the purposes
        of this Agreement.

Section 2.3.    No Dissenters Rights.  The holders of shares of Company
    Common Stock shall not be entitled to appraisal rights with respect
    to the Merger.

The Company represents and warrants to Parent and Sub as follows:

    with respect to Subsidiaries that in the aggregate do not constitute
    a "significant subsidiary" within the meaning of Regulation S-X,
    Rule 1-02 (w), such representations are being made to the best
    knowledge of the Company, and except, in the case of clause (iii),
    where the failure to have such power or the failure to be so

    Adverse Effect on the Company (as defined below).

    (a) Item 3.2 of the letter from the Company to Parent and Sub dated

        partnership, joint venture or other business association or
        entity.

        and other similar laws affecting creditors' rights generally and
        general principles of equity, regardless of whether asserted in
        a proceeding in equity or at law.

        loss of any material benefit) under, any of the terms,
        conditions or provisions of any loan, credit agreement, note,

        ability of the Company to perform its obligations under this
        Agreement or prevent the consummation of any of the transactions
        contemplated hereby.







    (c) No consent, approval, order or authorization of, or
        registration, declaration or filing with, any court,
        administrative agency, commission or other governmental

        orders, authorizations, filings, approvals, declarations and

        the time filed, complied in all material respects with the
        applicable requirements of the Securities Act and the Exchange
        Act, as the case may be, and (ii) did not at the time they were
        filed (or if amended or superseded by a subsequent filing, then
        on the date of such filing) contain any untrue statement of a
        material fact or omit to state a material fact required to be
        stated in such Company SEC Reports or necessary in order to make
        the statements in such the Company SEC Reports, in the light of
        the circumstances under which they were made, not misleading.

        forms, reports or other documents with the SEC.

    (b) Each of the consolidated financial statements (including, in
        each case, any related notes) contained in the Company SEC
        Reports, including any Company SEC Reports filed from the date
        of this Agreement until the Closing (collectively, the "Company






        Financial Statements"), complied or will comply in all material
        respects with the applicable published rules and regulations of
        the SEC with respect thereto, was or will be prepared in
        accordance with United States generally accepted accounting
        principles ("GAAP") applied on a consistent basis throughout the
        periods involved (except as may be indicated in the notes to
        such financial statements or, in the case of unaudited
        statements, as permitted by Form 10-Q or 8-K promulgated by the
        SEC), and fairly presented or will fairly present the
        consolidated financial position of the Company and its
        Subsidiaries as at the respective dates and the consolidated
        results of its operations and cash flows for the periods
        indicated, except that the unaudited interim financial
        statements were or are subject to normal and recurring year-end
        adjustments which were not or are not expected to be material in
        amount. The unaudited consolidated balance sheet of the Company

    in Item 3.6 of the Company Letter or as otherwise disclosed in the
    Company SEC Reports filed and publicly available prior to the date
    of this Agreement, the Company and its Subsidiaries do not have any
    liabilities, either accrued or contingent (whether or not required
    to be reflected in financial statements in accordance with United
    States generally accepted accounting principles), and whether due or
    to become due, which individually or in the aggregate could
    reasonably be expected to have a Material Adverse Effect on the
    Company, other than liabilities reflected in the Company Balance
    Sheet and normal or recurring liabilities incurred since September
    30, 1997 in the ordinary course of business consistent with past
    practices which would not individually or in the aggregate have a
    Material Adverse Effect on the Company.

Section 3.7.    Absence of Certain Changes or Events.  Since the date of
    the Company Balance Sheet, the Company and its Subsidiaries have
    conducted their businesses only in the ordinary course in a manner
    consistent with past practice (except as disclosed in the Company
    SEC Reports filed and publicly available prior to the date of this
    Agreement), and since such date there has not been: (a) any Material
    Adverse Effect on the Company or any facts or circumstances that
    could reasonably be expected to result in a Material Adverse Effect
    on the Company; (b) any damage, destruction or loss (whether or not
    covered by insurance) with respect to the Company or any of its
    Subsidiaries having a Material Adverse Effect on the Company; (c)
    any material change by the Company or any of its Subsidiaries in its
    accounting methods, principles or practices; (d) any revaluation by
    the Company or any of its Subsidiaries of any of its assets having a
    Material Adverse Effect on the Company, including writing down the
    value of capitalized software or inventory or writing off notes or
    accounts receivable other than in the ordinary course of business
    consistent with past practice; or (e) except as disclosed in Item
    3.7 of the Company Letter, any other action or event that would have







    required the consent of Parent pursuant to clauses (a), (c) or (g)
    of Section 5.1 of this Agreement had such action or event occurred
    after the date of this Agreement.

Section 3.8.    Taxes.
    (a) For purposes of this Agreement, a "Tax" or, collectively,
        "Taxes" means any and all federal, state, local and foreign
        taxes, assessments and other governmental charges, duties,
        impositions and liabilities of any kind whatsoever, including,

        by gross receipts, income, profits, sales, use and occupation,
        and value added, ad valorem, transfer, franchise, withholding,
        payroll, recapture, employment, excise and property taxes (in
        all cases, together with all interest, penalties and additions
        imposed with respect to such amounts) and including any
        liability for taxes of a predecessor entity.

    (b) Except as disclosed in Item 3.8 of the Company Letter, each of
        the Company and its Subsidiaries has prepared and timely filed
        (or will so file) all federal, state, local and foreign returns,

        examined by the appropriate taxing authority or the period for
        assessment of the Taxes in respect of which such Returns were
        required to be filed has expired.







    (g) Except as disclosed in Item 3.8 of the Company Letter, there is

        affiliate has actual knowledge could reasonably be expected to

    (a) Except as disclosed in Item 3.10(a) of the Company Letter, the
        Company and its Subsidiaries own, or are licensed or otherwise

        relating to the Company Intellectual Property Rights or any
        material license, sublicense or other agreement pursuant to

        right of any third party; and (iii) to the best knowledge of the
        Company the manufacturing, marketing, licensing or sale of the
        Company's products does not infringe any patent, trademark,
        service mark, copyright, trade secret or other proprietary right

Section 3.11.   Agreements, Contracts and Commitments.  Neither the
    Company nor any of its Subsidiaries has breached, or received in
    writing any claim or threat (for which there is a reasonable basis)
    that it has breached, any of the terms or conditions of any material
    agreement, contract or commitment to which it is a party or to which






    any of its assets and properties is subject ("Company Material
    Contracts") in such a manner as would permit any other party to
    cancel, modify the terms of or terminate the same or would permit
    any other party to collect material damages from the Company or any
    of its Subsidiaries under any Company Material Contract.  Each
    Company Material Contract that has not expired or been terminated is
    in full force and effect and is not subject to any material default
    thereunder of which the Company is aware by any party obligated to
    the Company or any of its Subsidiaries pursuant to such Company
    Material Contract. All Company Material Contracts are filed as
    exhibits to the Company SEC Reports or are listed in Item 3.11 of
    the Company Letter.  Except as set forth in Item 3.11 of the Company
    Letter, neither the Company nor any of its Subsidiaries is a party
    to or bound by any non-competition agreement or any other agreement
    or obligation which purports to limit in any material respect the

    Subsidiary is entitled to conduct all or any material portion of the
    business of the Company and its Subsidiaries taken as whole.

Section 3.12.   Litigation.  There is no action, suit or proceeding,
    claim, arbitration or, to the knowledge of the Company,
    investigation against the Company or any of its Subsidiaries pending
    or, to the knowledge of the Company, threatened, or as to which the
    Company or any of its Subsidiaries has received any written notice
    of assertion, which, if decided adversely to the Company or such
    Subsidiary, could reasonably be expected to have a Material Adverse
    Effect on the Company or impair the ability of the Company to
    consummate 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, insofar as reasonably can
    be foreseen, in the future would have any such effect.

Section 3.13.   Environmental Matters.
    (a) Except as set forth in Item 3.13 of the Company Letter, the
        Company has no reason to believe (i) that any underground
        storage tanks are present under any property that the Company or
        any of its Subsidiaries has at any time owned, operated,
        occupied or leased or (ii) that any amount of any substance that
        has been designated by any Governmental Entity or by applicable
        federal, state or local law to be radioactive, toxic, hazardous
        or otherwise a danger to health or the environment, including
        PCBs, asbestos, petroleum, urea-formaldehyde and all substances
        listed as hazardous substances pursuant to the Comprehensive
        Environmental Response, Compensation, and Liability Act of 1980,
        as amended, or defined as a hazardous waste pursuant to the
        United States Resource Conservation and Recovery Act of 1976, as
        amended, and the regulations promulgated pursuant to said laws
        (a "Hazardous Material"), is present, as a result of actions of
        the Company or any of its Subsidiaries or actions of any third
        party or otherwise, in, on or under any property, including the
        land and the improvements, ground water and surface water, that
        the Company or any of its Subsidiaries has at any time owned,
        operated, occupied or leased, where the presence of such






        underground storage tanks or Hazardous Material would be
        reasonably likely to have a Material Adverse Effect on the
        Company; provided that the handling or use of a Hazardous
        Material in compliance with applicable standards or permits
        shall not be included in this representation.

    (b) At no time has the Company or any of its Subsidiaries
        transported, stored, used, manufactured, disposed of, released
        or exposed its employees or others to Hazardous Materials in
        violation of any law in effect on or before the Closing Date,
        nor has the Company or any of its Subsidiaries disposed of,
        transported, sold, or manufactured any product containing a
        Hazardous Material (collectively, "Hazardous Materials
        Activities") in violation of any rule, regulation, treaty or
        statute promulgated by any Governmental Entity to prohibit,
        regulate or control Hazardous Materials or any Hazardous
        Material Activity, which violation has had or is reasonably
        likely to have a Material Adverse Effect on the Company.

    (c) The Company and its Subsidiaries currently hold all
        environmental approvals, permits, licenses, clearances and
        consents (the "Environmental Permits") necessary for the conduct
        of the Hazardous Material Activities and other businesses of the
        Company and its Subsidiaries as such activities and businesses
        are currently being conducted in all material respects.

    (d) No action, proceeding, revocation proceeding, amendment
        procedure, writ, injunction or claim is pending or, to the
        knowledge of the Company, threatened concerning any
        Environmental Permit or any Hazardous Materials Activity of the
        Company or any of its Subsidiaries and the Company is not aware
        of any fact or circumstance which could (i) involve the Company
        or any of its Subsidiaries in any environmental litigation
        which, if decided adversely to the Company and its Subsidiaries,
        could have a Material Adverse Effect on the Company, or (ii)
        impose upon the Company or any of its Subsidiaries any
        environmental liability which would have a Material Adverse
        Effect on the Company

Section 3.14.   Employee Benefit Plans.
    (a) The Company has made available to Parent all employee benefit
        plans (as defined in Section 3(3) of the Employee Retirement
        Income Security Act of 1974, as amended ("ERISA")), all
        employment, termination and consulting agreements, all bonus,
        stock option, stock appreciation right, restricted stock, stock
        purchase, incentive, deferred compensation, supplemental
        retirement, severance and other similar employee benefit plans
        and agreements, and all unexpired severance plans and
        agreements, written or otherwise, for the benefit of, or
        relating to, any current or former employee of the Company or
        any of its Subsidiaries or any trade or business (whether or not
        incorporated) or other organization that together with the
        Company is treated as a single employer under Section 414 of the
        Code (collectively, the "Company Employee Plans").  Neither the






        Company nor any of its Subsidiaries, nor any trade or business
        (whether or not incorporated) or other organization that
        together with the Company is treated as a single employer under
        Section 414 of the Code maintains or has ever in the past
        maintained or contributed to any employee benefit plan subject
        to Title IV of ERISA (including a multiemployer plan as defined
        in Section 3(37) of ERISA).  Item 3.14 of the Company Letter
        contains a list of all of the Company Employee Plans.

    (b) With respect to each Company Employee Plan, the Company has made
        available to Parent, a true and correct copy of (i) the most
        recent annual report (Form 5500) filed with the Internal Revenue
        Service if such Company Employee Plan is subject to such filing
        requirement, (ii) such Company Employee Plan, (iii) any trust
        agreement or group annuity contract relating to such Company
        Employee Plan and (iv) the most recent determination letter
        issued with respect to any Company Employee Plan which is
        intended to be qualified under Section 401(a) of the Code.

    (c) With respect to the Company Employee Plans, no event has
        occurred, and to the knowledge of the Company there exists no
        condition or set of circumstances, in connection with which,
        individually or in the aggregate, the Company or any of its
        Subsidiaries could be subject to any material liability,
        including the loss of income Tax deductions under ERISA, the
        Code or any other applicable law.

    (d) With respect to the Company Employee Plans, individually and in
        the aggregate, there are no material funded benefit obligations
        for which contributions have not been made or properly accrued
        and there are no material unfunded benefit obligations that have
        not been accounted for by reserves, or otherwise properly
        footnoted in accordance with United States generally accepted
        accounting principles, on the Company Financial Statements.

    (e) Except as disclosed in Item 3.14 of the Company Letter, neither
        the Company nor any of its Subsidiaries is a party to any oral
        or written (i) union or collective bargaining agreement, (ii)
        agreement with any officer or other key employee of the Company
        or any of its Subsidiaries, the benefits of which are
        contingent, or the terms of which are materially altered, upon
        the occurrence of any of the transactions contemplated by this
        Agreement or upon such occurrence coupled with a subsequent
        event, (iii) agreement with any officer or key employee of the
        Company or any of its Subsidiaries providing any term of
        employment or compensation guarantee, or (iv) agreement or plan,
        including any Company Employee Plan, any of the benefits of
        which will be increased, or the vesting or exercisability of the
        benefits of which will be accelerated, by the occurrence of any
        of the transactions contemplated by this Agreement or the value
        of any of the benefits of which will be calculated on the basis
        of any of the transactions contemplated by this Agreement.
        Except as set forth in Item 3.14 of the Company Letter, Section
        162 (m) of the Code does not limit the deductibility of any






        compensation payable to any officer of the Company, including
        compensation or benefits under any plan or agreement disclosed
        pursuant to the preceding sentence.

Section 3.15.   Compliance with Laws.  The Company and its Subsidiaries
    have complied with, are not in violation of, and have not received
    any notices of violations with respect to, any federal, state, local
    or foreign statute, law or regulation with respect to the conduct of
    their business, or ownership or operation of their business, except
    for failures to comply or violations which could not reasonably be
    expected to have a Material Adverse Effect on the Company or impair
    the ability of the Company to consummate the transactions
    contemplated by this Agreement.  There are no situations with
    respect to the Company which involved or involve (i) the use of any
    corporate funds for unlawful contributions, gifts, entertainment or
    other unlawful expenses related to political activity, (ii) the
    making of any direct or indirect unlawful payments to government
    officials or others from corporate funds or the establishment or
    maintenance of any unlawful or unrecorded funds, (iii) the violation
    of any of the provisions of The Foreign Corrupt Practices Act of
    1977, or any rules or regulations promulgated thereunder, or (iv)
    the receipt of any illegal discounts or rebates or any other
    violation of the antitrust laws.

Section 3.16.   Pooling.  Neither the Company nor any of its
    Subsidiaries, nor, to the knowledge of the Company, any of its
    affiliates, has taken or agreed to take any action that would
    prevent the Merger from being treated as a "pooling of interests"
    for financial accounting purposes in accordance with GAAP and
    applicable SEC regulations. The factual information to be provided
    by the Company to KPMG Peat Marwick LLP (the "Company Auditors"), in
    connection with their written opinion to be delivered pursuant to
    Section 7.1(f) will be correct in all material respects and will be
    provided to Parent

    has occurred that would be required to be reported by the Company
    pursuant to paragraphs (a), (b) or (c) of Item 404 of Regulation S-K
    promulgated by the SEC.  Other than the Services Agreement (as
    defined below) there are no agreements between the Company and any
    of its affiliates which are not required to be listed in Item 3.14
    of the Company Letter.  The loan agreement between the Company and
    Safeguard referenced in the Company's Proxy Statement for its 1997
    Annual Meeting of Stockholders has terminated and is of no force or
    effect and there are no amounts outstanding thereunder.








Section 3.19.   Registration Statement; Proxy Statement/Prospectus.  The
    information supplied by the Company for inclusion in the
    registration statement of Parent on Form S-4 pursuant to which
    shares of Parent Common Stock issued in the Merger will be
    registered with the SEC (the "Registration Statement") shall not
    contain, at the time the Registration Statement is declared
    effective by the SEC, any untrue statement of a material fact or
    omit to state any material fact required to be stated in the
    Registration Statement or necessary in order to make the statements
    in the Registration Statement, in light of the circumstances under
    which they were made, not misleading. The information supplied by
    the Company for inclusion in the proxy statement/prospectus (the
    "Proxy Statement") to be sent to the stockholders of the Company in
    connection with the special meeting of the Company's stockholders to
    consider this Agreement and the Merger (the "Stockholders Meeting")
    shall not, on the date the Proxy Statement is first mailed to
    stockholders of the Company, at the time of the Stockholders Meeting
    or at the Effective Time, contain any statement which, at such time
    and in light of the circumstances under which it was made, is false
    or misleading with respect to any material fact, or omit to state
    any material fact necessary in order to make the statements made in
    the Proxy Statement not false or misleading or omit to state any
    material fact necessary to correct any statement in any earlier
    communication with respect to the solicitation of proxies for the
    Stockholders Meeting which has become false or misleading. If at any
    time prior to the Effective Time any event relating to the Company
    or any of its affiliates should be discovered by the Company which
    should be set forth in an amendment to the Registration Statement or
    a supplement to the Proxy Statement, the Company shall promptly
    inform Parent.

Section 3.20.   No Excess Parachute Payments.  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 Company Employee Plan currently in effect would not
    be characterized as an "excess parachute payment" (as such term is
    defined in Section 280G of the Code).

    the Company, Robert W. Baird & Co., Inc., has delivered to the
    Company an opinion dated as of the date of this Agreement to the
    effect that the Exchange Ratio is fair from a financial point of
    view to the holders of the Company Common Stock and a copy of such
    opinion has been made available to Parent.

Section 3.22.   Section 203 of the DGCL Not Applicable.  The
    restrictions contained in Section 203 of the DGCL applicable to a
    "business combination" (as defined in Section 203) will not apply to

    consummation of the Merger or the other transactions contemplated
    hereby.

    Stock approving this Agreement is the only vote of holders of any
    class or series of the Company's capital stock necessary to approve
    this Agreement and the transactions contemplated hereby.

    advisor or other person, other than Robert W. Baird & Co., Inc., 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.  A true and complete copy of the Company's engagement lette
    with Robert W. Baird & Co., Inc. has been made available to Parent.

        action on the part of Parent. This Agreement has been duly
        executed and delivered by Parent and constitutes the valid and
        binding obligations of Parent, enforceable in accordance with
        the terms hereof, except as such enforceability may be limited
        by bankruptcy, insolvency, reorganization, moratorium and other
        similar laws affecting creditors' rights generally and general
        principles of equity, regardless of whether asserted in a
        proceeding in equity or at law.







    (b) The execution and delivery of this Agreement by Parent and Sub
        do not, and the consummation of the transactions contemplated by
        this Agreement will not, (i) conflict with, or result in any
        violation or breach of, any provision of the Certificate of
        Incorporation or Bylaws of Parent or Sub (in each case as
        heretofore amended), (ii) result in any violation or breach of,
        or constitute (with or without notice or lapse of time, or both)

        benefit) under, any of the terms, conditions or provisions of
        any loan, credit agreement, note, bond, mortgage, indenture,
        lease, contract or other agreement, instrument or obligation to
        which Parent or any of its Subsidiaries is a party or by which
        any of them or any of their properties or assets may be bound,
        or (iii) subject to the consents, approvals, orders,
        authorizations, filings, declarations and registrations
        specified in Section 4.3(c), conflict with or violate any
        judgment, order, decree, statute, law, ordinance, rule or
        regulation or any permit, concession, franchise or license
        applicable to Parent or any of its Subsidiaries or any of their
        properties or assets, except in the case of clause (ii) and
        (iii) for any such violations, breaches, defaults, terminations,
        cancellations or accelerations which in the aggregate could not
        reasonably be expected to have a Material Adverse Effect on
        Parent and do not impair the ability of Parent to perform its
        obligations under this Agreement or prevent the consummation of
        any of the transactions contemplated hereby.

    (c) No consent, approval, order or authorization of, or
        registration, declaration or filing with, any Governmental
        Entity is required by or with respect to Parent or any of its

        with the Securities Act and the entry of an order by the SEC
        permitting the Registration Statement to become effective; (iii)
        the filing of the Certificate of Merger with the Secretary of

        approvals, orders, authorizations, filings, declarations and
        registrations which, in the aggregate, if not obtained or made,
        could not reasonably be expected to have a Material Adverse
        Effect on Parent or impair the ability of Parent to perform its
        obligations under this Agreement.

    (a) Parent has filed and made available to the Company or its legal
        counsel all forms, reports and documents required to be filed by
        Parent with the SEC (collectively, the "Parent SEC Reports")
        since January 1, 1995. The Parent SEC Reports (i) at the time
        filed, complied in all material respects with the applicable
        requirements of the Securities Act and the Exchange Act, as the
        case may be, and (ii) did not at the time they were filed (or if
        amended or superseded by a subsequent filing, then on the date
        of such filing) contain any untrue statement of a material fact
        or omit to state a material fact required to be stated in such
        Parent SEC Reports or necessary in order to make the statements
        in such Parent SEC Reports, in the light of the circumstances
        under which they were made, not misleading. None of Parent's
        Subsidiaries is required to file any forms, reports or other
        documents with the SEC.

        this Agreement until the Closing, complied or will comply in all
        material respects with the applicable published rules and
        regulations of the SEC with respect thereto, was or will be
        prepared in accordance with GAAP applied on a consistent basis
        throughout the periods involved (except as may be indicated in
        the notes to such financial statements or, in the case of
        unaudited statements, as permitted by Form 10-Q or 8-K
        promulgated by the SEC), and fairly presented or will fairly

        Subsidiaries as at the respective dates and the consolidated
        results of its operations and cash flows for the periods
        indicated, except that the unaudited interim financial
        statements were or are subject to normal and recurring year-end
        adjustments which were not or are not expected to be material in
        amount. The unaudited consolidated balance sheet of Parent as of

    to be reflected in financial statements in accordance with United
    States generally accepted accounting principles), and whether due or
    to become due, which individually or in the aggregate could
    reasonably be expected to have a Material Adverse Effect on Parent,
    other than (i) liabilities reflected in the Parent Balance Sheet,
    and (ii) normal or recurring liabilities incurred since September
    30, 1997 in the ordinary course of business consistent with past
    practices which would not individually or in the aggregate have a
    Material Adverse Effect on Parent.








Section 4.7.    Absence of Certain Changes or Events.  Between the date
    of the Parent Balance Sheet and the date hereof,  Parent and its
    Subsidiaries have conducted their businesses only in the ordinary

    prior to the date of this Agreement).  Except with respect to the
    matters set forth in Item 4.6 of the Parent Letter, since the Parent
    Balance Sheet Date there has not been: (a) any Material Adverse
    Effect on Parent or any facts or circumstances that could reasonably
    be expected to result in a Material Adverse Effect on Parent; (b)
    any damage, destruction or loss (whether or not covered by
    insurance) with respect to Parent or any of its Subsidiaries having
    a Material Adverse Effect on Parent; (c) any material change by
    Parent or any of its Subsidiaries in its accounting methods,
    principles or practices; or (d) any revaluation by Parent or any of
    its Subsidiaries of any of its assets having a Material Adverse
    Effect on Parent, including writing down the value of capitalized

        required to be filed at or before the Effective Time relating to
        any and all Taxes concerning or attributable to Parent or any of
        its Subsidiaries or to their operations, and such Returns are
        true and correct and have been completed in accordance with
        applicable law, except where any such failure to prepare or file
        timely or any such failure to be true and correct, or any such
        failure to be completed in accordance with applicable law would
        not individually, or in the aggregate, have a Material Adverse
        Effect on Parent.

    (b) Except as disclosed in Item 4.8 of the Parent Letter, each of
        Parent and its Subsidiaries as of the Effective Time will have
        paid all Taxes it is required to pay prior to the Effective

        Material Adverse Effect on Parent.

    (c) Except as disclosed in Item 4.8 of the Parent Letter, there is
        no material United States federal or state income Tax deficiency
        outstanding or assessed against Parent or any of its

        as a liability on the Parent Balance Sheet nor has Parent or any
        of its Subsidiaries executed any waiver of any statute of
        limitations on or extending the period for the assessment or
        collection of any material United States federal or state income
        Tax.

    (d) Except as disclosed in Item 4.8 of the Parent Letter, there is
        no action, suit, investigation, audit, claim or assessment
        pending or proposed or threatened in writing with respect to






        Taxes of Parent or any of its Subsidiaries that, if decided
        adversely to Parent, would have a Material Adverse Effect on
        Parent.

    (e) Except as disclosed in Item 4.8 of the Parent Letter, there are
        no liens for Taxes upon the assets of Parent or any of its
        Subsidiaries except liens relating to current Taxes not yet due
        and except where such liens would not have a Material Adverse
        Effect on Parent.

    (f) Except as disclosed in Item 4.8 of the Parent Letter, all Taxes
        which Parent or any of its Subsidiaries are required by law to
        withhold or to collect for payment have been duly withheld and
        collected, and have been paid or accrued, reserved against and
        entered on the books of Parent, except where any such failure to
        withhold or collect or such failure to pay or accrue, reserve
        against and enter would not individually, or in the aggregate,
        have a Material Adverse Effect on Parent.

    (g) Except as disclosed in Item 4.8 of the Parent Letter, neither
        Parent nor any of its Subsidiaries has any material liability
        for unpaid federal, state, local or foreign Taxes that has not
        been accrued for or reserved on the Parent Balance Sheet,
        whether asserted or unasserted, contingent or otherwise, except
        where such liability would not have a Material Adverse Affect on
        Parent.

    (h) Neither Parent nor any of its Subsidiaries, nor any of its other
        affiliates (i) has taken any action, agreed to take any action,
        or failed to take any action, or (ii) has knowledge of any fact
        or circumstance that (without regard to any action taken or
        agreed to be taken by the Company or any of its affiliates), in
        each case, Parent, such Subsidiary or such other affiliate has
        actual knowledge could reasonably be expected to cause the
        Merger to fail to qualify as a "reorganization" within the
        meaning of Section 368(a) of the Code.

Section 4.9.    Properties.  Parent and its Subsidiaries own or have
    valid leasehold interests in all real property necessary for the
    conduct of their businesses in all material respects as presently
    conducted. All material leases to which Parent or any of its
    Subsidiaries is a party are in good standing, valid and effective in
    accordance with their respective terms, and neither Parent nor its
    Subsidiaries is in default under any of such leases, except where
    the lack of such good standing, validity and effectiveness or the
    existence of such default could not reasonably be expected to have a
    Material Adverse Effect on Parent.

Section 4.10.   Intellectual Property.  Except with respect to the
    matters set forth in Item 4.6 of the Parent Letter, Parent and its
    Subsidiaries own, or are licensed or otherwise possess, legally
    enforceable rights to use, all patents, trademarks, trade names,
    service marks, copyrights and mask works, any applications for and
    registrations of such patents, trademarks, trade names, service






    marks, copyrights and mask works, and all processes, formulae,
    methods, schematics, technology, know how, computer software
    programs or applications and tangible or intangible proprietary
    information or material that are necessary to conduct the business
    of Parent and its Subsidiaries as currently conducted or planned to
    be conducted by Parent and its Subsidiaries except where the failure
    to have such ownership or possession could not reasonably be
    expected to have a Material Adverse Effect on Parent.

Section 4.11.   Agreements, Contracts and Commitments.  Neither Parent
    nor any of its Subsidiaries has breached, or received in writing any
    claim or threat (for which there is a reasonable basis) that it has
    breached, any of the terms or conditions of any material agreement,
    contract or commitment to which it is a party or to which any of its
    assets is subject ("Parent Material Contracts") in such a manner as
    would permit any other party to cancel, modify the terms of or
    terminate the same or would permit any other party to collect
    material damages from Parent or any of its Subsidiaries under any
    Parent Material Contract.  Each Parent Material Contract that has
    not expired or been terminated is in full force and effect and is
    not subject to any material default thereunder of which Parent is
    aware by any party obligated to Parent or any of its Subsidiaries
    pursuant to such Parent Material Contract.

    to the knowledge of Parent, threatened, or as to which Parent or any
    of its Subsidiaries has received any written notice of assertion,
    which, if decided adversely to Parent or such Subsidiary, could
    reasonably be expected to have a Material Adverse Effect on Parent
    or impair the ability of Parent to consummate 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, insofar as reasonably can be foreseen, in the future would
    have any such effect.

Section 4.13.   Environmental Matters.
    (a) Except as set forth in Item 4.13 of the Parent Letter, Parent
        has no reason to believe (i) that any underground storage tanks
        are present under any property that Parent or any of its
        Subsidiaries has at any time owned, operated, occupied or leased
        or (ii) that any Hazardous Material is present, as a result of
        actions of Parent or any of its Subsidiaries or actions of any
        third party or otherwise, in, on or under any property,
        including the land and the improvements, ground water and
        surface water, that Parent or any of its Subsidiaries has at any
        time owned, operated, occupied or leased, where the presence of
        such underground storage tanks or Hazardous Material would be
        reasonably likely to have a Material Adverse Effect on Parent;








        provided that the handling and use of a Hazardous Material in
        compliance with applicable standards or permits shall not be
        included in this representation.

    (b) At no time has Parent or any of its Subsidiaries transported,
        stored, used, manufactured, disposed of, released or exposed its
        employees or others to Hazardous Materials in violation of any
        law in effect on or before the Closing Date, nor has Parent or
        any of its Subsidiaries engaged in Hazardous Materials
        Activities in violation of any rule, regulation, treaty or
        statute promulgated by any Governmental Entity to prohibit,
        regulate or control Hazardous Materials or any Hazardous
        Materials Activity, which violation has had or is reasonably
        likely to have a Material Adverse Effect on Parent.

    (c) Parent and its Subsidiaries currently hold all Environmental
        Permits necessary for the conduct of the Hazardous Materials
        Activities and other businesses of Parent and its Subsidiaries
        as such activities and businesses are currently being conducted.

    (d) Parent is not aware of any fact or circumstance which could (i)
        involve Parent or any of its Subsidiaries in any environmental
        litigation which, if decided adversely to Parent and its
        Subsidiaries, could have a Material Adverse Effect on Parent, or
        (ii) impose upon Parent or any of its Subsidiaries any
        environmental liability which would have a Material Adverse
        Effect on Parent.

Section 4.14.   Pooling.  Neither Parent nor any of its Subsidiaries,
    nor, to the knowledge of Parent, any of its affiliates has taken or
    agreed to take any action that would prevent the Merger from being
    treated as a "pooling of interests" for financial accounting
    purposes in accordance with GAAP and applicable SEC regulations. The
    factual information to be provided by Parent to the Ernst & Young
    LLP, ("Parent Auditors")  in connection with their written opinion
    to be delivered pursuant to Section 7.1(f) will be correct in all
    material respects.

Section 4.15.   Affiliates.  Except for the persons listed on Item 4.15

    Parent, may be deemed to be affiliates of Parent under Rule 1-02 of
    Regulation S-X of the SEC.

Section 4.16.   Compliance with Laws.  Parent and its Subsidiaries have
    complied with, are not in violation of, and have not received any
    notices of violations with respect to, any federal, state, local or
    foreign statute, law or regulation with respect to the conduct of
    their business, or ownership or operation of their business, except
    for failures to comply or violations which could not reasonably be
    expected to have a Material Adverse Effect on Parent or impair the
    ability of Parent to consummate the transactions contemplated by
    this Agreement. There are no situations with respect to Parent which
    involved or involve (i) the use of any corporate funds for unlawful
    contributions, gifts, entertainment or other unlawful expenses






    related to political activity, (ii) the making of any direct or
    indirect unlawful payments to government officials or others from
    corporate funds or the establishment or maintenance of any unlawful
    or unrecorded funds, (iii) the violation of any of the provisions of
    The Foreign Corrupt Practices Act of 1977, or any rules or
    regulations promulgated thereunder, or (iv) the receipt of any
    illegal discounts or rebates or any other violation of the antitrust
    laws.

Section 4.17.   Registration Statement; Proxy Statement/Prospectus.  The
    information supplied by Parent for inclusion in the Registration
    Statement shall not contain, at the time the Registration Statement
    is declared effective by the SEC, any untrue statement of a material
    fact or omit to state any material fact required to be stated in the
    Registration Statement or necessary in order to make the statements
    in the Registration Statement, in light of the circumstances under
    which they were made, not misleading. The information supplied by
    Parent for inclusion in the Proxy Statement to be sent to the
    stockholders of the Company in connection with the Stockholders
    Meeting shall not, on the date the Proxy Statement is first mailed
    to stockholders of the Company, at the time of the Stockholders
    Meeting or at the Effective Time, contain any statement which, at
    such time and in light of the circumstances under which it was made,
    is false or misleading with respect to any material fact, or omit to
    state any material fact necessary in order to make the statements
    made in the Proxy Statement not false or misleading or omit to state
    any material fact necessary to correct any statement in any earlier
    communication with respect to the solicitation of proxies for the
    Stockholders Meeting which has become false or misleading. If at any
    time prior to the Effective Time any event relating to Parent or any
    of its affiliates should be discovered by Parent which should be set
    forth in an amendment to the Registration Statement or a supplement
    to the Proxy Statement, Parent shall promptly inform the Company.

Section 4.18.   Interim Operations of Sub.  Sub was formed solely for
    the purpose of engaging in the transactions contemplated by this
    Agreement, has engaged in no other business activities, and has
    conducted its operations only as contemplated by this Agreement.

    Parent is required to approve this Agreement and the transactions
    contemplated hereby.

Section 4.20.   Brokers.  No broker, investment banker, financial

    commission in connection with the transactions contemplated by this
    Agreement based upon arrangements made by or on behalf of Parent or
    Sub.

Section 5.1.    Covenants of the Company.  During the period from the
    date of this Agreement to the Effective Time, the Company agrees as
    to itself and its Subsidiaries (except to the extent that Parent

    usual, regular and ordinary course in substantially the same manner
    as previously conducted, to pay its debts and Taxes when due subject
    to good faith disputes over such debts or Taxes, to pay or perform

    business organization, (ii) keep available the services of its
    present officers and key employees, and (iii) preserve its
    relationships with customers, suppliers, distributors, licensors,
    licensees and others having business dealings with it.  The Company

    occurrence that would result in a material breach of any covenant or
    agreement of the Company set forth in this Agreement or cause any
    representation or warranty of the Company set forth in this
    Agreement to be untrue if made as of the date of, and giving effect
    to, such event or occurrence, which if uncured, could reasonably be
    expected to cause any condition set forth in Section 7.2(a) or
    7.2(b) not to be satisfied. Except as expressly contemplated by this
    Agreement, the Company shall not (and shall not permit any of its
    Subsidiaries to), without the prior written consent of Parent:

    (a) accelerate, amend or change the period of exercisability of
        options or restricted stock granted under any of the Company

    date of, and giving effect to, such event or occurrence, which if
    uncured, could reasonably be expected to cause any condition set
    forth in Section 7.2(a) or 7.2(b) not to be satisfied.  Between the
    date hereof and April 16, 1998, except as expressly contemplated by
    this Agreement, Parent shall not (and shall not permit any of its
    Subsidiaries to), without the prior written consent of the Company:

    (a) declare or pay any dividends on or make any other distributions

        distributions by a direct or indirect wholly owned subsidiary of
        Parent to its parent) in respect of any of its capital stock, or
        split, combine or reclassify any of its capital stock or issue

        division or any interest therein to the extent all such
        acquisitions together involve purchase prices in excess of five
        hundred million dollars ($500,000,000) in the aggregate, it
        being agreed that nothing in this Agreement shall prohibit
        Parent or any of its Subsidiaries from engaging in discussions
        or negotiations or from furnishing information in connection
        with any acquisitions or transactions;







    (d) sell, lease, license, mortgage, encumber or otherwise dispose of

        warrants or rights to acquire any debt securities or guarantee
        any debt securities of others, enter into any "keep well" or
        other agreement to maintain any financial statement condition of
        another person or enter into any arrangement having the economic
        effect of any of the foregoing, or (y) make any loans, advances
        or capital contributions to, or investments in, any other
        person, other than to the Parent or any of its wholly owned
        Subsidiaries, to the extent involving in the case of all of the
        matters described in clauses (x) and (y) more than two hundred
        fifty million dollars ($250,000,000) in the aggregate; or

    (g) take, or agree in writing or otherwise to take, any of the
        actions described in the foregoing clauses (a) through (f), or
        any action (other than actions of the type contemplated by
        clauses (a) through (f) above which are permitted thereby) which
        (i) would make any of Parent's representations or warranties in
        this Agreement, if made on and as of the date of such action or
        agreement, untrue or incorrect in any material respect, or (ii)
        could prevent it from performing, or cause it not to perform,
        its obligations under this Agreement.  Nothing contained in this
        Agreement shall prohibit Parent from adopting a stockholders
        rights plan or issuing securities pursuant thereto.

Section 5.3.    Employment Agreements.  The Company may enter into
    employment agreements, effective as of the Effective Time, with the
    officers of the Company listed in Item 5.3(a) of the Parent Letter
    (the "Senior Officers"), which employment agreements shall be in the
    form attached as Item 5.3(b) of the Parent Letter and shall be
    subject to the terms specified in Item 5.3(c) of the Parent Letter.

Section 5.4.    Cooperation.  Subject to compliance with applicable law,

    representatives of Parent to report operational matters of
    materiality and the general status of ongoing operations and (ii)
    each of Parent and the Company shall promptly provide the other

    with any Governmental Entity in connection with this Agreement, the
    Merger and the other transactions contemplated hereby.








Section 5.5.    Material Adverse Effect   For purposes of this
    Agreement, "Material Adverse Effect" means, when used in connection
    with the Company or Parent, any change or effect that is materially
    adverse to the business, properties, assets, condition (financial or
    otherwise), or results of operations of such party and its
    Subsidiaries taken as a whole but excluding (i) any change resulting
    from general economic conditions or general industry conditions or
    (ii) any change caused by the transactions contemplated by this
    Agreement and the public announcement thereof.



                               ARTICLE VI

                         ADDITIONAL AGREEMENTS

Section 6.1.   No Solicitation.
    (a) The Company agrees that, from the date of this Agreement until
        the earlier of the Effective Time or the termination of this
        Agreement in accordance with Section 8.1, it shall not, directly
        or indirectly, and shall cause its officers, directors,
        employees, representatives, agents, and affiliates, to not (i)
        solicit, initiate, or encourage any inquiries or proposals that
        constitute, or could reasonably be expected to lead to, a
        proposal or offer for a merger, consolidation, sale or purchase
        of substantial assets or stock, tender or exchange offer, or
        other business combination or change in control or similar
        transaction involving the Company or any of its Subsidiaries,
        other than the transactions contemplated or permitted by this
        Agreement (any of the foregoing inquiries or proposals being
        referred to in this Agreement as a "Takeover Proposal"), (ii)
        engage in negotiations or discussions concerning, or provide any
        non-public information to any person or entity relating to, any
        Takeover Proposal, or (iii) enter into any agreement with
        respect to, agree to, approve or recommend any Takeover
        Proposal; provided, however, that nothing contained in this
        Agreement shall prevent the Company or its Board of Directors,
        directly or through representatives or agents on behalf of the
        Board of Directors, from (A) furnishing non-public information
        to, or entering into discussions or negotiations with, any
        person or entity in connection with an unsolicited bona fide
        written Takeover Proposal by such person or entity, if and only
        to the extent that (1) such Takeover Proposal would, if
        consummated, result in a transaction that would, in the
        reasonable good faith judgment of the Board of Directors of the
        Company, after consultation with its financial advisors, result
        in a transaction more favorable to the Company's stockholders
        from a financial point of view than the Merger (any such more
        favorable Takeover Proposal being referred to in this Agreement
        as a "Superior Proposal") and, in the reasonable good faith
        judgment of the Board of Directors of the Company, after
        consultation with its financial advisors, the person or entity
        making such Superior Proposal has the financial means to
        conclude such transaction, (2) the failure to take such action






        would in the reasonable good faith judgment of the Board of
        Directors of the Company, on the basis of the advice of the
        outside corporate counsel of the Company, be contrary to the
        fiduciary duties of the Board of Directors of the Company to the
        Company's stockholders under applicable law; (3) prior to
        furnishing such non-public information to, or entering into
        discussions or negotiations with, such person or entity, such
        Board of Directors receives from such person or entity an
        executed confidentiality agreement with provisions not less
        favorable to the Company than those contained in the
        Confidentiality and Non Disclosure Agreement dated December 29,
        1997 between Parent and the Company, except for the provision of
        Section 7 thereof (the "Confidentiality Agreement") and (4) the
        Company shall have fully complied with this Section 6.1; or (B)
        complying with Rule 14d-9 and Rule 14e-2 promulgated under the
        Exchange Act with regard to a Takeover Proposal.

    (b) The Company shall notify Parent no later than twenty-four (24)
        hours after receipt by the Company (or its advisors) of any
        Takeover Proposal or any request for nonpublic information in
        connection with a Takeover Proposal or for access to the
        properties, books or records of the Company by any person or
        entity that informs the Company that it is considering making,
        or has made, a Takeover Proposal.  Such notice to Parent shall
        be made orally and in writing and shall indicate in reasonable
        detail the identity of the person or entity making the Takeover
        Proposal and the terms and conditions of such proposal, inquiry
        or contact. If the financial terms of such Takeover Proposal are
        modified, then the Company shall notify Parent of the terms and
        conditions of such modification within twenty-four (24) hours of
        the receipt of such modification.  The Company shall also notify
        Parent simultaneously with the delivery of notice to the
        directors of the Company of, and in any event at least
        twenty-four (24) hours prior to (unless a longer period is
        required by Section 6.1(c)), each meeting of the Board of
        Directors at which the Company will consider taking definitive
        action with respect to withdrawing or modifying, in a manner
        adverse to Parent, its recommendation to the Company's
        stockholders in favor of approval of the Merger.

    (c) Notwithstanding the foregoing, in the event that there exists a
        Superior Proposal before the Board of Directors of the Company
        and in the reasonable good faith judgment of the Company, on the
        basis of the advice of the outside corporate counsel of the
        Company, the failure to accept such Superior Proposal would be
        contrary to the fiduciary duties of the Board of Directors of
        the Company to the Company's stockholders under applicable law,
        the Board of Directors of the Company may pursuant to Section
        8.1(h) (subject to this and the following sentences) terminate
        this Agreement prior to the Stockholders Meeting (and
        concurrently with such termination, cause the Company to enter
        into an acquisition agreement with respect to such Superior
        Proposal), but only at a time that is (i) after the third day
        following Parent's receipt of written notice advising Parent






        that the Board of Directors of the Company is prepared to accept
        a Superior Proposal, specifying the material terms and
        conditions of such Superior Proposal and identifying the person
        making such Superior Proposal;  (ii) after the payment by the
        Company to Parent of the Termination Fee in full and in
        immediately available funds; and (iii) after the Company shall
        have, and shall have caused its financial and legal advisors to,
        negotiate in good faith with Parent to make such changes to the
        terms and conditions of this Agreement as would enable the
        Company to proceed with the transactions contemplated hereby.

    (d) During the period from the date of this Agreement through the
        Effective Time, the Company shall not terminate, amend, modify
        or waive any provision of any confidentiality or standstill
        agreement (other than any entered into in the ordinary course of
        business not in connection with any possible Takeover Proposal)
        to which it or any of its Subsidiaries is a party (other than
        any between the Company and its Subsidiaries).  During such
        period, the Company shall enforce, to the fullest extent
        permitted under applicable law, the provisions of any such
        agreement, including, but not limited to, by obtaining
        injunctions to prevent any breaches of such agreements and to
        enforce specifically the terms and provisions thereof in any
        court of the United States of America or of any state having
        jurisdiction.

Section 6.2.   Proxy Statement/Prospectus; Registration.
    (a) As promptly as practicable after the execution of this
        Agreement, Parent and the Company shall prepare and file with
        the SEC the Proxy Statement, and Parent shall prepare and file
        with the SEC the Registration Statement, in which the Proxy
        Statement will be included. Parent and the Company shall use all
        reasonable best efforts to cause the Registration Statement to
        become effective as soon after such filing as reasonably
        practicable. The Proxy Statement shall include the
        recommendation of the Board of Directors of the Company to the
        stockholders of the Company in favor of approval and adoption of
        this Agreement and the Merger; provided, however, that such
        Board of Directors shall not be required to make, and shall be
        entitled to withdraw or modify, such recommendation if (i) the
        Company has complied with Section 6.1 and (ii) in the reasonable
        good faith judgment of such Board of Directors, on the basis of
        the advice of outside corporate counsel of the Company, the
        making of, or the failure to withdraw or modify, such
        recommendation would be contrary to the fiduciary duties of such
        Board of Directors to the Company's stockholders under
        applicable law.  The Board of Directors of the Company shall not
        rescind its declaration that this Agreement and the Merger are
        advisable unless, in any such case, each of the conditions set
        forth in clauses (i) and (ii) immediately above is satisfied.

    (b) Each of Parent and the Company shall make all necessary filings
        with respect to the Merger under the Securities Act and the
        Exchange Act and applicable state securities laws and the rules






        and regulations thereunder, and shall use its reasonable best
        efforts to obtain all permits and other authorizations required
        under applicable state securities laws for the issuance of the
        shares of Parent Common Stock pursuant to the Merger.

Section 6.3.    Consents.  Each of Parent and the Company shall use
    reasonable best efforts to obtain all necessary consents, waivers
    and approvals under its respective material agreements, contracts,
    licenses or leases required for the consummation of the Merger and
    the other transactions contemplated by this Agreement.

Section 6.4.    Current Nasdaq Quotation.  Parent shall continue the
    quotation of Parent Common Stock, and the Company shall continue the
    quotation of the Company Common Stock, on The Nasdaq National Market
    during the term of this Agreement to the extent necessary so that
    appraisal rights will not be available to stockholders of the
    Company under Section 262 of the DGCL.

Section 6.5.    Access to Information.  Upon reasonable notice, the
    Company shall  (and shall cause each of its Subsidiaries to) afford
    to the officers, employees, accountants, financial advisors, counsel
    and other representatives of Parent, access, during normal business
    hours during the period prior to the Effective Time, to all its
    properties, books, contracts, commitments, Returns, and records and,
    during such period, the Company shall (and shall cause each of its
    Subsidiaries to) furnish promptly to Parent (i) a copy of each
    report, schedule, registration statement and other document filed or
    received by it during such period pursuant to the requirements of
    federal securities laws and (ii) all other information concerning
    its business, properties and personnel as Parent may reasonably
    request; provided, however, that the Company's obligation to provide
    information pursuant to this Section 6.5 shall be subject to Item
    6.5 of the Company Letter.  During the period prior to the Effective
    Time, Parent shall provide the financial advisor of the Company
    identified in Section 3.24 and the Chief Executive Officer of the
    Company reasonable access to senior executive officers of Parent, as
    appropriate, in connection with the transactions contemplated by
    this Agreement.  No information or knowledge obtained in any
    investigation pursuant to this Section 6.5 shall affect or be deemed
    to modify any representation or warranty contained in this Agreement
    or the conditions to the obligations of the parties to consummate
    the Merger. Unless otherwise required by law, Parent and the Company
    will hold, and will use its reasonable best efforts to cause their
    respective officers, employees, affiliates and representatives to
    hold, any nonpublic information received from the other party to
    this Agreement, any of their respective Subsidiaries or any of their
    respective representatives (other than information already in the
    possession of such party at the time of receipt of such information
    from the other party) 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 reasonable best
    efforts to ensure that such officers, employees, affiliates and
    representatives 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 of termination of this Agreement for any reason,
    Parent and the Company shall promptly return or destroy all

    documents.

    hold the Stockholders Meeting as promptly as practicable after the
    date hereof for the purpose of voting upon the adoption of this
    Agreement and the approval of the Merger. Subject to Section 6.1,
    the Company, through its Board of Directors, shall recommend that
    the Company's stockholders vote in favor of the adoption of this
    Agreement and the approval of the Merger (and shall not withdraw or
    modify such recommendation) and shall otherwise use its best efforts
    to solicit from its stockholders proxies in favor of such matters
    and to obtain the requisite approval of the Company's stockholders;
    provided, however, that such Board of Directors shall not be
    required to make, and shall be entitled to withdraw or modify, such
    recommendation if (i) the Company has complied with Section 6.1 and
    (ii) in the reasonable good faith judgment of such Board of
    Directors, on the basis of advice of outside corporate counsel of
    the Company, the making of, or the failure to withdraw or modify,
    such recommendation would be contrary to the fiduciary duties of
    such Board of Directors to the Company's stockholders under
    applicable law.

Section 6.7.   Legal Conditions to Merger.
    (a) Each of Parent and the Company shall take reasonable actions
        necessary to comply promptly with all legal requirements which
        may be imposed on such party with respect to the Merger (which
        actions shall include, without limitation, furnishing all
        information required under the HSR Act and in connection with
        approvals of or filings with any other Governmental Entity) and
        shall promptly cooperate with and, subject to applicable law,
        furnish information to each other in connection with any such
        requirements imposed upon either of them or any of their
        Subsidiaries in connection with the Merger.  Each of Parent and
        the Company shall, and shall cause its Subsidiaries to take
        reasonable actions necessary to obtain (and shall cooperate with
        each other in obtaining) any consent, authorization, order or
        approval of, or any exemption by, any Governmental Entity or
        other third party, required to be obtained or made by the
        Company, Parent or any of their Subsidiaries for any of the
        conditions set forth in Article VII to be satisfied (any of the
        foregoing, an "Approval") or the taking of any action required
        in furtherance thereof or otherwise contemplated thereby or by
        this Agreement.

    (b) Notwithstanding anything to the contrary contained in this
        Agreement, neither Parent nor the Company shall have any
        obligation to oppose, challenge or appeal any suit, action or
        proceeding by any Governmental Entity before any court or
        governmental authority, agency or tribunal, domestic or foreign
        or any order or ruling by any such body, (i) seeking to restrain






        or prohibit or restraining or prohibiting the consummation of
        the Merger or any of the other transactions contemplated by this
        Agreement, (ii) seeking to prohibit or limit or prohibiting or
        limiting the ownership, operation or control by the Company,
        Parent or any of their respective Subsidiaries of any portion of
        the business or assets of the Company, Parent or any of their
        respective Subsidiaries, or (iii) seeking to compel or
        compelling the Company, Parent or any of their respective
        Subsidiaries to dispose of, grant rights in respect of, or hold
        separate any portion of the business or assets of the Company,
        Parent or any of their respective Subsidiaries.  Further,
        notwithstanding anything to the contrary contained in this
        Agreement, Parent shall have no obligation to dispose of, grant
        rights in respect of, or hold separate any portion of the
        business or assets of the Company, Parent or any of their
        respective Subsidiaries or to agree to any of the foregoing.
        Neither the Company nor any of its Subsidiaries shall take any
        of the actions described in preceding sentences of this Section
        6.7(b) without the prior written consent of Parent.

Section 6.8.    Public Disclosure.  Except as otherwise required by

    the publication of any press release or other public announcement or
    disclosure with respect to the transactions contemplated by this

    opportunity to review and comment upon any such release or
    announcement prior to publication of the same.

    each use its reasonable best efforts to cause the Merger to be
    treated as a "reorganization" within the meaning of Section 368(a)
    of the Code, and to enable its respective counsel to render the
    opinions contemplated by Sections 7.2(e) and 7.3(d).  Each party
    shall make (to the extent it can truthfully do so), and shall use
    all reasonable best efforts to cause those of its respective
    stockholders that counsel to the parties shall reasonably request to
    make, such representations and certifications as counsel to the
    parties shall reasonably request to enable them to render such
    opinions including, without limitation, the representations of
    Parent contained in a certificate of Parent (the "Parent Tax
    Certificate") substantially in the form of the Parent Tax
    Certificate attached as Item 6.9 of the Parent Letter and
    representations of the Company contained in a certificate of the
    Company (the "Company Tax Certificate") substantially in the form of
    the Company Tax Certificate attached as Item 6.9 of the Company
    Letter.

Section 6.10.   Pooling Accounting.  Parent and the Company shall each
    use its reasonable best efforts to cause the business combination to
    be effected by the Merger to be accounted for as a pooling of
    interests. The Company shall use its reasonable best efforts  to






    cause its affiliates not to take any action that would adversely
    affect the ability of Parent to account for the business combination
    to be effected by the Merger as a pooling of interests.

Section 6.11.   Affiliate Letters.  Between the date of this Agreement
    and the Effective Time, the Company will use its reasonable best
    efforts to cause each of the persons listed on Item 3.17 of the
    Company Letter to execute and deliver to Parent an executed letter
    agreement, substantially in the form of Exhibit A hereto (the
    "Company Affiliate Letter"), and Parent will use its reasonable best
    efforts to cause each of the persons listed on Item 4.15 of the
    Parent Letter to execute and deliver to Parent an executed letter
    agreement, substantially in the form of Exhibit B hereto (the
    "Parent Affiliate Letter").  Between the date of this Agreement and
    the Effective Time, the Company shall, if requested, promptly
    provide Parent such information and documents as Parent shall
    reasonably request for purposes of determining the affiliates of the
    Company and upon the request of Parent use its reasonable best
    efforts to cause any person who may in the reasonable judgment of
    Parent be deemed an affiliate of the Company to execute and deliver
    to Parent the Company Affiliate Letter.  Parent shall be entitled to
    place appropriate legends on the certificates evidencing any Parent
    Common Stock to be received by affiliates of the Company pursuant to
    this Agreement and to issue appropriate stop transfer instructions
    to the transfer agent for the Parent Common Stock, consistent with
    the terms of the Company Affiliate Letter.

Section 6.12.   Nasdaq Quotation.  Parent shall use its reasonable best
    efforts to cause the shares of Parent Common Stock to be issued in

        Company Stock Option to purchase the Company Common Stock under
        the Company Stock Plans the notice (if any) required pursuant to
        such plans in connection with the Merger.

    (b) From and after the Effective Time, each outstanding Company
        Stock Option (including both vested and unvested Company Stock
        Options) shall be assumed by Parent and shall pursuant to the
        terms of such options, be deemed to constitute an option to
        acquire, on the same terms and conditions as were applicable
        under such Company Stock Option, the same number of shares of
        Parent Common Stock as the holder of such Company Stock Option
        would have been entitled to receive in the Merger pursuant to
        this Agreement had such holder exercised such option in full
        immediately prior to the Effective Time (rounded down to the
        nearest whole number), at a price per share (rounded up to the
        nearest whole cent) equal to the quotient of (i) the exercise
        price per share of Company Common Stock pursuant to such Company
        Stock Option divided by (ii) the Exchange Ratio.  All other
        terms of such Company Stock Options shall remain in effect.







    (c) The Company shall take all actions necessary so that following
        the Effective Time no holder of a Company Stock Option or any
        participant in any Company Benefit Plan shall have any right
        thereunder to acquire capital stock of the Company, Sub, or the
        Surviving Corporation.  The Company shall take all actions
        necessary so that, as of the Effective Time, none of Sub, the
        Company, the Surviving Corporation or any of their respective
        Subsidiaries is or will be bound by any Company Stock Options,
        other options, warrants, rights or agreements which would
        entitle any person, other than Parent, Sub or its affiliates, to
        own any capital stock of the Company, Sub, the Surviving
        Corporation or any of their respective subsidiaries or to
        receive any payment in respect thereof, except as otherwise
        provided in Article I and Section 6.13(b).

Section 6.14.   Indemnification.  All rights to indemnification for acts
    or omissions occurring prior to the Effective Time now existing in
    favor of the current or former directors or officers of the Company
    provided in the Company's Certificate of Incorporation and Bylaws
    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 (6)
    years from the Effective Time and to the extent the Surviving
    Corporation fails to perform its obligations with respect thereto,
    Parent shall perform such obligations. Parent and the Surviving
    Corporation will cause to be maintained for a period of not less
    than six (6) years from the Effective Time the Company's current
    directors and officers insurance and indemnification policy (a copy
    of which has been provided to Parent) to the extent that it provides
    coverage for events occurring prior to the Effective Time for all
    persons who are directors and officers of the Company on the date of
    this Agreement; provided, however, that in no event shall the
    Surviving Corporation be required to pay a premium in any one year
    in excess of one hundred fifty thousand dollars ($150,000), and
    provided, further, that if the annual premiums of such insurance
    coverage exceed such amount or if such existing directors' and
    officers' insurance and indemnification policy expires, is
    terminated or canceled during such six-year period, the Surviving
    Corporation shall be obligated to obtain a policy with the greatest
    coverage available for a cost not exceeding one hundred fifty
    thousand dollars ($150,000).

Section 6.15.   Additional Agreements; Reasonable Efforts.  Subject to
    the terms and conditions of this Agreement, each of the parties
    agrees to use all reasonable best efforts to take, or cause to be
    taken, all action and to do, or cause to be done, all things
    necessary, proper or advisable under applicable laws and regulations
    to consummate and make effective the transactions contemplated by
    this Agreement, subject to the appropriate vote of the stockholders
    of the Company described in Section 6.6, including cooperating fully
    with the other party, providing information and making all necessary
    filings under the HSR Act.








Section 6.16.   Termination of Certain Agreements.  The Company shall
    cause the Administrative Services Agreement (the "Services
    Agreement"), dated as of May 7, 1997 between the Company and
    Safeguard Scientifics, Inc. ("Safeguard"), to be terminated
    effective as of the Effective Time (or such later time thereafter as
    may be requested by Parent, not to exceed one hundred eighty (180)
    days following the Effective Time) on terms that are reasonably
    satisfactory to Parent, which terms shall include that the Company
    shall have no continuing obligations under such agreement following
    such termination and that Safeguard shall not be entitled to receive
    any consideration in connection with such termination other than a
    termination fee equal to the Services Fee (as defined in Section 3
    of the Services Agreement) payable with respect to the period
    commencing on the date of such termination and ending on December
    31, 1998.

Section 6.17.   Real Estate Transfer Taxes.  Either the Company or the
    Surviving Corporation shall pay all state or local real property
    transfer, gains or similar Taxes, if any (collectively, the
    "Transfer Taxes"), attributable to the transfer of the beneficial
    ownership of the Company's and its Subsidiaries' real properties,
    and any penalties or interest with respect thereto, payable in
    connection with the consummation of the Merger.  The Company shall
    cooperate with Parent in the filing of any returns with respect to
    the Transfer Taxes, including supplying in a timely manner a
    complete list of all real property interests held by the Company and
    its Subsidiaries and any information with respect to such properties
    that is reasonably necessary to complete such returns.  The portion
    of the consideration allocable to the real properties of the Company
    and its Subsidiaries shall be determined by Parent and the Company
    in their reasonable discretion.  The shareholders of the Company
    (who are intended third-party beneficiaries of this Section 6.17)
    shall be deemed to have agreed to be bound by the allocation
    established pursuant to this Section 6.17 in the preparation of any
    Return with respect to the Transfer Taxes.

        for purposes of this Section 7.2(d) unless Parent pays the
        Company two million dollars ($2,000,000) in immediately
        available funds.

    (e) Tax Opinion.  Parent shall have received an opinion of Sidley &
        Austin, in form and substance reasonably satisfactory to Parent,
        dated the Effective Time, substantially to the effect that, on
        the basis of facts, representations and assumptions set forth in
        such opinion that are consistent with the state of facts
        existing as of the Effective Time, for federal income tax
        purposes:

        (i)     the Merger will constitute a "reorganization" within the
                meaning of Section 368(a) of the Code, and the Company,
                Sub and Parent will each be a party to such
                reorganization within the meaning of Section 368(b) of
                the Code;

                received in lieu of fractional shares of Parent Common
                Stock;

        (iv)    the aggregate tax basis of the shares of Parent Common
                Stock received solely in exchange for Company Common
                Stock pursuant to the Merger (including fractional
                shares of Parent Common Stock for which cash is
                received) will be the same as the aggregate tax basis of
                the Company Common Stock exchanged therefor;

        (v)     the holding period for shares of Parent Common Stock
                received solely in exchange for Company Common Stock
                pursuant to the Merger will include the holding period
                of the Company Common Stock exchanged therefor, provided
                such Company Common Stock was held as a capital asset by
                the stockholder at the Effective Time; and

        (vi)    a stockholder of the Company who receives cash in lieu
                of a fractional share of Parent Common Stock will
                recognize gain or loss equal to the difference, if any,
                between such stockholder's tax basis in such fractional
                share (as described in clause (iv) above) and the amount
                of cash received.

        In rendering such opinion, counsel may rely upon representations
        of Parent (including, without limitation, representations
        contained in the Parent Tax Certificate), representations of the

        suit, action or proceeding by any Governmental Entity before any
        court or governmental authority, agency or tribunal, domestic or
        foreign, (i) seeking to restrain or prohibit the consummation of
        the Merger or any of the other transactions contemplated by this
        Agreement or seeking to obtain from the Company, Parent or Sub
        any damages in connection therewith, (ii) seeking to prohibit or

        respective Subsidiaries, or to compel the Company, Parent or any
        of their respective Subsidiaries to dispose of, grant rights in
        respect of, or hold separate any portion of the business or
        assets of the Company, Parent or any of their respective
        Subsidiaries, or (iii) which otherwise is reasonably likely to
        have a Material Adverse Effect on the Company.

    (d) Tax Opinion.  The Company shall have received an opinion of
        Morgan, Lewis & Bockius LLP, in form and substance reasonably
        satisfactory to the Company, dated the Effective Time,
        substantially to the effect that, on the basis of facts,
        representations and assumptions set forth in such opinion that
        are consistent with the state of facts existing as of the
        Effective Time, for federal income tax purposes:

        (i)     the Merger will constitute a "reorganization" within the
                meaning of Section 368(a) of the Code, and the Company,
                Sub and Parent will each be a party to such
                reorganization within the meaning of Section 368(b) of
                the Code.

        (ii)    no gain or loss will be recognized by Parent, Sub or the
                Company as a result of the Merger;

        (iii)   no gain or loss will be recognized by the stockholders
                of the Company upon the exchange of their Company Common
                Stock solely for shares of Parent Common Stock pursuant






                to the Merger, except with respect to cash, if any,
                received in lieu of fractional shares of Parent Common
                Stock;

        (iv)    the aggregate tax basis of the shares of Parent Common
                Stock received solely in exchange for Company Common
                Stock pursuant to the Merger (including fractional
                shares of Parent Common Stock for which cash is
                received) will be the same as the aggregate tax basis of
                the Company Common Stock exchanged therefor;

        (v)     the holding period for shares of Parent Common Stock
                received solely in exchange for Company Common Stock
                pursuant to the Merger will include the holding period
                of the Company Common Stock exchanged therefor, provided
                such Company Common Stock was held as a capital asset by
                the stockholder at the Effective Time; and

        (vi)    a stockholder of the Company who receives cash in lieu
                of a fractional share of Parent Common Stock will
                recognize gain or loss equal to the difference, if any,
                between such stockholder's tax basis in such fractional
                share (as described in clause (iv) above) and the amount
                of cash received.

        In rendering such opinion, counsel may rely upon representations
        of Parent (including, without limitation, representations
        contained in the Parent Tax Certificate), representations of the
        Company (including, without limitation, representations
        contained in the Company Tax Certificate) and representations by
        others.

                       TERMINATION AND AMENDMENT

Section 8.1.    Termination.  This Agreement may be terminated at any
    time prior to the Effective Time (with respect to Sections 8.1(b)
    through 8.1(g), by written notice by the terminating party to the
    other party), whether before or after approval of the matters
    presented in connection with the Merger by the stockholders of the

    (b) by either Parent or the Company if the Merger shall not have
        been consummated by August 15, 1998 (provided, however, that the
        right to terminate this Agreement under this Section 8.1(b)
        shall not be available to any party whose failure to fulfill any
        obligation under this Agreement has been the cause of or
        resulted in the failure of the Merger to occur on or before such
        date); or







    (c) by either Parent or the Company if a court of competent
        jurisdiction or other Governmental Entity shall have issued a
        final order, decree or ruling, or taken any other action, having
        the effect of permanently restraining, enjoining or otherwise
        prohibiting the Merger, and all appeals with respect to such
        order, decree, ruling or action have been exhausted or the time
        for appeal of such order, decree, ruling or action shall have
        expired (provided, however, that the right to terminate this

        any party which has not complied with its obligations under
        Section 6.7); or

    (d) by either Parent or the Company if, at the Stockholders Meeting
        (including any adjournment or postponement thereof), the
        requisite vote of the Company stockholders in favor of this
        Agreement and approval of the Merger shall not have been
        obtained (provided, however, that the right to terminate this
        Agreement under this Section 8.1(d) shall not be available to
        the Company if it has not complied with its obligations under
        Sections 6.1, 6.2 and 6.6, and no termination shall be effective
        by the Company if it has not complied with its obligations under
        Section 8.3, if applicable, of this Agreement); or

        committee thereof shall have withdrawn or modified its
        recommendation of this Agreement or the Merger to the Company's
        stockholders in a manner adverse to Parent; (ii) an Alternative
        Transaction (as defined in Section 8.3(f)) involving the Company
        shall have taken place or the Board of Directors of the Company
        or any committee thereof shall have recommended such an
        Alternative Transaction (or a proposal or offer therefor) to the
        stockholders of the Company or shall have publicly announced its
        intention to recommend such an Alternative Transaction (or a
        proposal or offer therefor) to the stockholders of the Company
        or to engage in an Alternative Transaction or shall have failed
        to recommend against such Takeover Proposal; or (iii) a tender
        offer or exchange offer for any of the outstanding shares of the
        Company Common Stock shall have been commenced or a registration
        statement with respect thereto shall have been filed (other than
        by Parent or an affiliate thereof) and the Board of Directors of
        the Company or any committee thereof shall have (A) recommended
        that the stockholders of the Company tender their shares in such
        tender or exchange offer or (B) publicly announced its intention
        to take no position with respect to such tender or exchange
        offer; or

    (f) by Parent if a breach of any representation, warranty, covenant
        or agreement on the part of the Company set forth in this
        Agreement shall have occurred which if uncured would cause any
        condition set forth in Sections 7.2(a) or 7.2(b) not to be
        satisfied, and such breach is incapable of being cured or, if








        capable of being cured, shall not have been cured within twenty
        (20) business days following receipt by the Company of written
        notice of such breach from Parent; or

    (g) by the Company if a breach of any representation, warranty,
        covenant or agreement on the part of Parent set forth in this
        Agreement shall have occurred which if uncured would cause any
        conditions set forth in Section 7.3(a) or 7.3(b) not to be
        satisfied, and such breach is incapable of being cured or, if
        capable of being cured, shall not have been cured within twenty
        (20) business days following receipt by Parent of written notice
        of such breach from the Company; or

    (h) by the Company in accordance with Section 6.1(c); provided that
        in order for the termination of this Agreement pursuant to this
        paragraph (h) to be deemed effective, and as a condition
        thereto, the Company shall have complied with all provisions
        contained in Section 6.1, including the notice provisions
        therein, and with all the applicable requirements of Section
        8.3, including the payment of the Termination Fee.

Section 8.2.    Effect of Termination.  In the event of any termination
    of this Agreement pursuant to Section 8.1, there shall be no
    liability or obligation on the part of Parent, the Company, Sub, or
    any of their respective officers, directors, stockholders or
    affiliates, except as set forth in Section 8.3.  The foregoing
    limitations shall not apply, and the remedies provided by Section
    8.3 shall not be exclusive, to the extent that such termination
    results from the willful breach by a party of any of its material
    representations, warranties, covenants or agreements in this
    Agreement. The provisions of Section 8.3 of this Agreement shall
    remain in full force and effect and survive any termination of this
    Agreement.

Section 8.3.   Fees and Expenses.

    (a) Except as set forth in this Section 8.3, all fees and expenses
        incurred in connection with this Agreement and the transactions
        contemplated hereby shall be paid by the party incurring such
        expenses, whether or not the Merger is consummated; provided,
        however, that Parent and the Company shall share equally all
        fees and expenses, other than attorneys' and accounting fees and
        expenses, incurred in relation to the printing and filing of the
        Proxy Statement (including any related preliminary materials)
        and the Registration Statement (including financial statements
        and exhibits) and any amendments or supplements thereto and the
        fee(s) required to be paid by Parent in connection with the
        filing(s) required under the HSR Act and applicable foreign laws
        (if any) in connection with the transactions contemplated by
        this Agreement; provided, further, that the amount of fees and
        expenses to be paid by the Company pursuant to the immediately
        preceding proviso shall not exceed two hundred thousand dollars
        ($200,000).







    (b) If any Takeover Proposal is made between the date hereof and the
        termination of this Agreement, and  this Agreement is terminated
        (i) by Parent pursuant to Section 8.1(f), or (ii) by Parent or
        the Company pursuant to Section 8.1(d) as a result of the
        failure to receive the requisite vote for adoption of this
        Agreement and approval of the Merger by the stockholders of the
        Company at the Stockholders Meeting, then if an Alternative
        Transaction involving the Company shall take place or the
        Company shall enter into any letter of intent, agreement in
        principle, acquisition agreement or other similar agreement with
        respect to an Alternative Transaction (each, an "Acquisition
        Agreement") within twelve (12) months of such termination, then
        the Company shall pay to Parent a termination fee in the amount
        of twelve million dollars ($12,000,000) (the "Termination Fee")
        simultaneously with the earlier to occur of such Alternative
        Transaction or execution of such Acquisition Agreement.

    (c) If this Agreement is terminated by Parent pursuant to Section
        8.1(e), then the Company shall pay to Parent the Termination Fee
        no later than one business day following such termination.

    (d) If this Agreement is terminated by the Company pursuant to
        Section 8.1(h), then the Company shall pay to Parent the
        Termination Fee prior to, and as a condition to, effectiveness
        of such termination.

    (e) Any Termination Fee payable under this Section 8.3 shall be paid
        in immediately available funds.

    (f) As used in this Agreement, an "Alternative Transaction"
        involving the Company means (i) a transaction or series of
        transactions pursuant to which any person or group (as such term
        is defined under the Exchange Act), other than Parent or Sub, or
        any affiliate thereof (a "Third Party"), acquires (or would
        acquire upon completion of such transaction or series of
        transactions) more than thirty-five percent (35%) of the equity
        securities or voting power of the Company or any of its
        Subsidiaries, pursuant to a tender offer or exchange offer or
        otherwise, (ii) a merger, consolidation, share exchange or other
        business combination involving the Company or any of its
        Subsidiaries pursuant to which any Third Party acquires
        ownership (or would acquire ownership upon consummation of such
        merger, consolidation, share exchange or other business
        combination) of more than thirty-five percent (35%) of the
        outstanding equity securities or voting power of the Company or
        any of its Subsidiaries or of the entity surviving such merger
        or business combination or resulting from such consolidation,
        (iii) any other transaction or series of transactions pursuant
        to which any Third Party acquires (or would acquire upon
        completion of such transaction or series of transactions)
        control of assets of the Company or any of its Subsidiaries
        (including, for this purpose, outstanding equity securities of
        Subsidiaries of such party) having a fair market value equal to
        more than thirty-five percent (35%) of the fair market value of






        all the consolidated assets of the Company immediately prior to
        such transaction or series of transactions, or (iv) any
        transaction or series of transactions pursuant to which any
        Third Party acquires (or would acquire upon completion of such
        transaction or series of transactions) control of the Board of
        Directors of the Company or by which nominees of any Third Party
        are (or would be) elected or appointed to a majority of the
        seats on the Board of Directors of the Company.

    hereto, by action taken or authorized by their respective Boards of
    Directors, at any time before or after approval of the matters

              FORM OF AFFILIATE LETTER FOR AFFILIATES OF
              COHERENT COMMUNICATIONS SYSTEMS CORPORATION
              -------------------------------------------


February __, 1998




Tellabs, Inc.
4951 Indiana Avenue
Lisle, Illinois  60532

Ladies and Gentlemen:

I have been advised that as of the date of this letter I may be deemed
to be an "affiliate" of Coherent Communications Systems Corporation, a
Delaware corporation (the "Company"), as the term "affiliate" is (i)
defined for purposes of paragraphs (c) and (d) of Rule 145 of the rules
and regulations (the "Rules and Regulations") of the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933,
as amended (the "Act"), and/or (ii) used in and for purposes of
Accounting Series Releases 130 and 135, as amended, of the Commission.
Pursuant to the terms of the Agreement and Plan of Merger dated as of
February 16, 1998 (the "Merger Agreement") among Tellabs, Inc., a
Delaware corporation ("Parent"), Cardinal Merger Co., a Delaware
corporation and a wholly owned subsidiary of Parent ("Sub"), and the
Company, Sub will be merged with and into the Company (the "Merger"),
with the Company surviving as a wholly-owned subsidiary of Parent.
Capitalized terms used in this letter without definition shall have the
meanings assigned to them in the Merger Agreement.

As a result of the Merger, I may receive shares of common stock, par
value $.01 per share, of Parent (the "Parent Shares") in exchange for
shares of the Company's Common Stock, par value $.01 per share (the
"Company Shares") owned by me or purchasable upon exercise of stock
options.

1.   I represent and warrant to, and covenant with, Parent as follows:
    A.  I shall not make any sale, transfer or other disposition of any
        Parent Shares in violation of the Act or the Rules and
        Regulations.

    B.  I have carefully read this letter and the Merger Agreement and
        have discussed the requirements of such documents and other
        applicable limitations upon my ability to sell, transfer or
        otherwise dispose of the Parent Shares, to the extent I felt
        necessary, with my counsel.








    C.  I have been advised that the issuance of the Parent Shares to me
        pursuant to the Merger has been or will be registered with the
        Commission under the Act on a Registration Statement on Form
        S-4. However, I have also been advised that, because at the time
        the Merger is submitted for a vote of the stockholders of the
        Company, (a) I may be deemed to be an "affiliate" of the Company
        and (b) the sale, transfer or other distribution by me of the
        Parent Shares has not been registered under the Act, I may not
        sell, transfer or otherwise dispose of the Parent Shares issued
        to me in the Merger unless (i) such sale, transfer or other
        disposition is made in conformity with the volume limitations
        and other conditions of Rule 145 promulgated by the Commission
        under the Act, (ii) such sale, transfer or other disposition has
        been registered under the Act or (iii) in the opinion of counsel
        reasonably acceptable to Parent, such sale, transfer or other
        disposition is otherwise exempt from registration under the Act.

    D.  I understand that Parent is under no obligation to register the
        sale, transfer or other disposition of any Parent Shares by me
        or on my behalf under the Act or to take any other action
        necessary in order to make compliance with an exemption from
        such registration available.

    E.  I will not, during the 30 days prior to the Effective Time,
        sell, transfer or otherwise dispose of or reduce my risk (as
        contemplated by SEC Accounting Series Release No. 135) with
        respect to the Company Shares or shares of the capital stock of
        Parent that I may hold and, furthermore, that I will not sell,
        transfer or otherwise dispose of or reduce my risk (as
        contemplated by SEC Accounting Series Release No. 135) with
        respect to the Parent Shares received by me in the Merger or any
        other shares of the capital stock of Parent until after such
        time as results covering at least 30 days of combined operations
        of the Company and Parent have been published by Parent, in the
        form of a quarterly earnings report, an effective registration
        statement filed with the Commission, a report to the Commission
        on Form 10-K, 10-Q, or 8-K, or any other public filing or
        announcement which includes the combined results of operations.
        Notwithstanding the foregoing, I understand that during the
        aforementioned period, subject to providing written notice to
        and obtaining the consent of Parent, which such consent shall
        not be unreasonably withheld, I will not be prohibited from de
        minimis dispositions and charitable contributions or bona fide
        gifts of the Parent Shares which, in each case, will not
        disqualify the accounting for the Merger as a pooling of
        interests.

2.  Execution of this letter should not be considered an admission on my
    part that I am an "affiliate" of the Company as described in the
    first paragraph of this letter, nor as a waiver of any rights I may
    have to object to any claim that I am such an affiliate on or after
    the date of this letter.








3.  I understand that the Parent may cause to be placed on the
    certificates of the Parent Shares issued to me, or any substitutions
    therefor, a legend stating in substance:

    "The shares represented by this certificate were issued pursuant to
    a business combination which is being accounted for as a pooling of
    interests in a transaction to which Rule 145, promulgated under the
    Securities Act of 1933, as amended, applies.  The shares have been
    acquired by the holder not with a view to, or for resale in
    connection with, any distribution thereof within the meaning of the
    Securities Act of 1933, as amended.  The shares may not be sold,
    pledged or otherwise transferred nor may any owner reduce the
    owner's risk relative thereto in any other way (i) until such time
    as Tellabs, Inc. shall have published financial results covering at
    least 30 days of combined operations after [Closing Date] and (ii)
    except in accordance with an exemption from the registration
    requirement of the Securities Act of 1933, as amended."

Very truly yours,

COHERENT COMMUNICATIONS TO BECOME SUBSIDIARY OF TELLABS

Lisle, Ill., -- Tellabs and Coherent Communications today
announced a merger agreement under which Coherent Communications
Systems Corporation of Ashburn, Va., USA, will become a
subsidiary of Tellabs.

Under the terms of the agreement, all outstanding shares of
Coherent stock will be exchanged at the ratio of 0.72 shares of
Tellabs common stock for each share of Coherent common stock.
Based on the closing price of Tellabs common stock on February,
13, 1998, the transaction is valued at approximately $670
million. Excluding one-time transaction costs of two
cents-to-three cents per share, modest earnings-per-share
accretion is expected in 1998 and 1999.

"In this era of convergence in the telecommunications industry,
the ability to bring the latest technology to global customers
in the shortest possible time is the key to growth," said
Tellabs President and CEO Michael J. Birck. "This transaction is
a strategic plus for Tellabs. The combination of Tellabs and
Coherent Communications allows us to bring sophisticated echo
canceller and speech processing technology to customers around
the world and provides us the resources to quickly explore new
uses for this technology. Coherent's focus on international
markets will nicely augment Tellabs' North American echo
canceller activity, and the combination should result in
innovative new speech enhancement products for both markets."

"I am very positive about merging our company with Tellabs. Our
core expertise in developing and selling equipment that enhances
voice quality will be strengthened by Tellabs' greater size and
resources," said Coherent's Chief Executive Officer Daniel L.
McGinnis. "By combining technologies and resources we will be
able to offer customers the greatest number of options that
enhance the network, improve customer satisfaction and
retention, and provide a competitive edge. We see this merger as
a real win for our customers, employees and stockholders."









For the immediate future, both the Tellabs and Coherent product
lines will be maintained to ensure that the needs of existing
customers are met. Following the merger, the combined company
will explore new product development activities as it seeks to
address the need for next-generation call-quality solutions.

The transaction is expected to be accounted for as a
pooling-of-interests and to qualify as a tax-free
reorganization. This transaction is subject to various
conditions and approval by appropriate government agencies and
Coherent stockholders. Coherent's Board of Directors has
unanimously approved the transaction and recommended its
approval by Coherent stockholders. Safeguard Scientifics,
Coherent's largest stockholder, has agreed to vote in favor of
the transaction.

Coherent (NASDAQ: CCSC) designs, manufactures and markets echo
cancellation and conferencing products for major international
telecommunications companies, cellular and PCS providers,
network operators, and Fortune 500 companies. Approximately 75
percent of Coherent's sales come from customers outside the
United States. Coupled with Tellabs' strong presence in the U.S.
echo canceller market, the combined company will be able to
effectively address the increasing demands for call quality in
wireline and wireless applications worldwide.

For its most current fiscal year, reported on January 20, 1998,
Coherent sales of $73,695,000 were 35 percent higher than 1996,
yielding net earnings of $13,979,000 or 90 cents per share as
compared to 63 cents per share for 1996. For the fourth quarter
of 1997, Coherent  sales of $20,809,000 yielded net earnings of
$4,366,000 or 28 cents per share.

Tellabs designs, manufactures, markets and services voice and
data transport and access systems. The company's products are
used worldwide by the providers of communications services.
Tellabs, Inc., stock is listed on the Nasdaq Stock Market
(TLAB).

This news release contains forward-looking statements that
involve risks and uncertainties. Actual results, including the
level of earnings of both Tellabs and Coherent Communications,
and the success of the proposed merger may differ from the
results discussed in the forward-looking statements. Factors
that might cause such a difference include, but are not limited
to, risks associated with acquisitions, such as difficulties in
the assimilation of operations, technologies and products of the
acquired companies, diversion of management's attention from
other business concerns, risks of entering new markets,
competitive response, and a downturn in the telecommunications
industry. For a more detailed description of the risk factors
associated with Tellabs and Coherent Communications, please
refer to the companies' respective SEC filings.
