                AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
 
     AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, as amended, dated as of
September 5, 1995 (this "Agreement"), among TERADYNE, INC., a Massachusetts
corporation ("Parent"), M MERGER CORP., a Delaware corporation and a wholly
owned subsidiary of Parent ("Merger Sub"), and MEGATEST CORPORATION, a Delaware
corporation (the "Company").
 
                             W I T N E S S E T H :
 
     WHEREAS, the Boards of Directors of Parent, Merger Sub and the Company have
each determined that it is advisable and in the best interests of their
respective stockholders for Parent to enter into a business combination with the
Company upon the terms and subject to the conditions set forth herein;
 
     WHEREAS, in furtherance of such combination, the Boards of Directors of
Parent, Merger Sub and the Company have each approved the merger (the "Merger")
of Merger Sub with and into the Company in accordance with the applicable
provisions of the Delaware General Corporation Law ("Delaware Law") upon the
terms and subject to the conditions set forth herein;
 
     WHEREAS, pursuant to the Merger, each outstanding share (a "Share") of the
Company's common stock, $0.001 par value per share (the "Company Common Stock"),
shall be converted into the right to receive the Merger Consideration (as
defined in Section 1.07(b)), upon the terms and subject to the conditions set
forth herein;
 
     WHEREAS, Parent, Merger Sub and the Company intend, by approving
resolutions authorizing this Agreement, to adopt this Agreement as a plan of
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), and the regulations thereunder, and to cause
the Merger to qualify as a reorganization under the provisions of Section 368(a)
of the Code;
 
     WHEREAS, for accounting purposes, it is intended that the transactions
contemplated hereby shall be accounted for as a pooling of interests under
United States generally accepted accounting principles ("GAAP");
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby,
Parent, Merger Sub and the Company hereby agree as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     SECTION 1.01. THE MERGER.
 
          (a) Effective Time.  At the Effective Time (as defined in Section
     1.02), and subject to and upon the terms and conditions of this Agreement
     and Delaware Law, Merger Sub shall be merged with and into the Company, the
     separate corporate existence of Merger Sub shall cease, and the Company
     shall continue as the surviving corporation. The Company as the surviving
     corporation after the Merger is hereinafter sometimes referred to as the
     "Surviving Corporation."
 
          (b) Closing.  Unless this Agreement shall have been terminated and the
     transactions herein contemplated shall have been abandoned pursuant to
     Section 7.01 and subject to the satisfaction or waiver of the conditions
     set forth in Article VI, the consummation of the Merger will take place as
     promptly as practicable (and in any event within two business days) after
     satisfaction or waiver of the conditions set forth in Article VI, at the
     offices of Testa, Hurwitz & Thibeault, 125 High Street, Boston,
     Massachusetts, unless another date, time or place is agreed to in writing
     by the parties hereto.
 
     SECTION 1.02. EFFECTIVE TIME.  As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, the parties
hereto shall cause the Merger to be consummated by filing a certificate of
merger as contemplated by Section 251 of Delaware Law (the "Certificate of
Merger"), together
 
                                        1
   6
 
with any required related certificates, with the Secretary of State of the State
of Delaware, in such form as required by, and executed in accordance with the
relevant provisions of, Delaware Law (the time of such filing being the
"Effective Time").
 
     SECTION 1.03. EFFECT OF THE MERGER.  At the Effective Time, the effect of
the Merger shall be as provided in this Agreement, the Certificate of Merger and
the applicable provisions of Delaware Law. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time all the property,
rights, privileges, powers and franchises of the Company and Merger Sub shall
vest in the Surviving Corporation, and all debts, liabilities and duties of the
Company and Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.
 
     SECTION 1.04. CERTIFICATE OF INCORPORATION; BY-LAWS.
 
          (a) Certificate of Incorporation.  Unless otherwise determined by
     Parent prior to the Effective Time, at the Effective Time the Certificate
     of Incorporation of Merger Sub, as in effect immediately prior to the
     Effective Time, shall be the Certificate of Incorporation of the Surviving
     Corporation until thereafter amended as provided by Delaware Law and such
     Certificate of Incorporation; provided, however, that Article I of the
     Certificate of Incorporation of the Surviving Corporation shall be amended
     to read as follows: "FIRST: The name of the corporation is MEGATEST
     Corporation."
 
          (b) By-Laws.  The By-Laws of Merger Sub, as in effect immediately
     prior to the Effective Time, shall be the By-Laws of the Surviving
     Corporation until thereafter amended as provided by Delaware Law, the
     Certificate of Incorporation of the Surviving Corporation and such By-Laws.
 
     SECTION 1.05. DIRECTORS AND OFFICERS.  The directors of Merger Sub
immediately prior to the Effective Time and the additional persons listed on
Schedule 1.05 of the Company Disclosure Schedule shall be the initial directors
of the Surviving Corporation, each to hold office in accordance with the
Certificate of Incorporation and By-Laws of the Surviving Corporation, and the
officers of the Company immediately prior to the Effective Time shall be the
initial officers of the Surviving Corporation, in each case until their
respective successors are duly elected or appointed and qualified.
 
     SECTION 1.06. EFFECT ON CAPITAL STOCK.  At the Effective Time, by virtue of
the Merger and without any action on the part of Parent, Merger Sub, the Company
or the holders of any of the following securities:
 
          (a) Conversion of Securities.  Each Share issued and outstanding
     immediately prior to the Effective Time (excluding any Shares to be
     canceled pursuant to Section 1.06(b) and any Dissenting Shares (as defined
     in Section 1.09)) shall be converted, subject to Section 1.06(f), into the
     right to receive .9091 shares (.9091, as adjusted pursuant to Section
     1.06(b), the "Exchange Ratio") of validly issued, fully paid and
     nonassessable shares of common stock of Parent, $.125 par value ("Parent
     Common Shares").
 
          (b) Adjustment of Conversion Ratio.  If the Final Parent Stock Price
     (as defined below) is equal to or less than $36.00 per share, no adjustment
     to the Exchange Ratio shall be made. If the Final Parent Stock Price is
     greater than $36.00 per share, then the Exchange Ratio shall be adjusted in
     accordance with the formula specified on Exhibit 1.06(b) hereto provided,
     however, that the Exchange Ratio as adjusted pursuant to this Section
     1.06(b) shall in no event be less than .8333. For purposes hereof, "Final
     Parent Stock Price" shall mean the average of the closing prices of the
     Parent Common Stock for the twenty consecutive days on which the Parent
     Common Shares are traded on The New York Stock Exchange (the "NYSE") ending
     on the fifth calendar day immediately preceding the Company Stockholders
     Meeting (as defined in Section 2.13).
 
          (c) Cancellation.  Each Share held in the treasury of the Company and
     each Share owned by Parent, Merger Sub or any direct or indirect wholly
     owned subsidiary of the Company or Parent immediately prior to the
     Effective Time shall, by virtue of the Merger and without any action on the
     part of the holder thereof, cease to be outstanding, be canceled and
     retired without payment of any consideration therefor and cease to exist.
 
                                        2
   7
 
          (d) Assumption of Stock Options; Stock Purchase Rights.  All options
     to purchase Company Common Stock then outstanding under the Company Stock
     Option Plans (as defined in Section 5.05) shall be assumed by Parent in
     accordance with Section 5.05. Immediately prior to the Effective Time, all
     rights to purchase Company Common Stock then outstanding under the Company
     Stock Purchase Plan (as defined in Section 5.06) shall be exercised in
     accordance with Section 5.06 and the shares so purchased shall be converted
     into Parent Common Shares at the Effective Time.
 
          (e) Capital Stock of Merger Sub.  Each share of common stock, $0.001
     par value per share, of Merger Sub issued and outstanding immediately prior
     to the Effective Time shall be converted into and exchanged for one validly
     issued, fully paid and nonassessable share of common stock, no par value,
     of the Surviving Corporation. Each stock certificate of Merger Sub
     evidencing ownership of any such shares shall continue to evidence
     ownership of such shares of capital stock of the Surviving Corporation.
 
          (f) Adjustments to Exchange Ratio.  The Exchange Ratio shall be
     adjusted to reflect fully the effect of any stock split, reverse split,
     stock dividend (including any dividend or distribution of securities
     convertible into Parent Common Shares or Company Common Stock),
     reorganization, recapitalization or other like change with respect to
     Parent Common Shares or Company Common Stock occurring after the date
     hereof and prior to the Effective Time.
 
          (g) Fractional Shares.  No fraction of a share of Parent Common Shares
     will be issued, but, except as provided in Section 5.05, in lieu thereof
     each holder of Company Common Stock who would otherwise be entitled to a
     fraction of a share of Parent Common Shares (after aggregating all
     fractional shares of Parent Common Shares to be received by such holder)
     shall receive from Parent an amount of cash (rounded to the nearest whole
     cent), without interest, equal to the product of (i) such fraction,
     multiplied by (ii) the average of the closing prices of Teradyne Common
     Stock for the twenty consecutive days on which Teradyne Common Stock is
     traded on the NYSE ending on the fifth calendar day immediately preceding
     the day on which the Special Meeting is held.
 
     SECTION 1.07. EXCHANGE OF CERTIFICATES.
 
          (a) Exchange Agent.  Immediately prior to the Effective Time, Parent
     shall supply, or shall cause to be supplied, to or for the account of a
     bank or trust company designated by Parent (the "Exchange Agent"), in trust
     for the benefit of the holders of Company Common Stock (other than
     Dissenting Shares), for exchange in accordance with this Section 1.07,
     through the Exchange Agent, certificates evidencing the Parent Common
     Shares issuable pursuant to Section 1.06 in exchange for outstanding Shares
     plus cash in an amount sufficient for payment in lieu of fractional shares
     as provided in Section 1.06(g).
 
          (b) Exchange Procedures.  Promptly after the Effective Time, Parent
     shall cause the Exchange Agent to mail to each holder of record of a
     certificate or certificates which immediately prior to the Effective Time
     evidenced outstanding Shares (other than Dissenting Shares) (the
     "Certificates") (i) a letter of transmittal (which shall specify that
     delivery shall be effected, and risk of loss and title to the Certificates
     shall pass, only upon proper delivery of the Certificates to the Exchange
     Agent and shall be in such form and have such other provisions as Parent
     may reasonably specify) and (ii) instructions to effect the surrender of
     the Certificates in exchange for the certificates evidencing shares of
     Parent Common Shares and, in lieu of any fractional shares thereof, cash.
     Upon surrender of a Certificate for cancellation to the Exchange Agent
     together with such letter of transmittal, duly executed, and such other
     customary documents as may be required pursuant to such instructions, the
     holder of such Certificate shall be entitled to receive in exchange
     therefor (A) certificates evidencing that number of whole Parent Common
     Shares which such holder has the right to receive in accordance with the
     Exchange Ratio in respect of the Shares formerly evidenced by such
     Certificate, (B) any dividends or other distributions to which such holder
     is entitled pursuant to Section 1.07(c), and (C) cash in lieu of fractional
     Parent Common Shares to which such holder is entitled pursuant to Section
     1.06(g) (the Parent Common Shares, dividends, distributions and cash
     described in this clause (C) being, collectively, 
     
 

                                        3
   8
     the "Merger Consideration"), and the Certificate so surrendered shall
     forthwith be canceled. In the event of a transfer of ownership of Shares
     which is not registered in the transfer records of the Company as of the
     Effective Time, Parent Common Shares and cash may be issued and paid in
     accordance with this Article I to a transferee if the Certificate
     evidencing such Shares is presented to the Exchange Agent, accompanied by
     all documents required to evidence and effect such transfer pursuant to
     this Section 1.07(b) and by evidence that any applicable stock transfer
     taxes have been paid. Until so surrendered, each outstanding Certificate
     that, prior to the Effective Time, represented shares of the Company Common
     Stock will be deemed from and after the Effective Time, for all corporate
     purposes, other than the payment of dividends, to evidence the ownership of
     the number of full shares of Parent Common Shares into which such shares of
     the Company Common Stock shall have been so converted and the right to
     receive an amount in cash in lieu of the issuance of any fractional shares
     in accordance with Section 1.06.
 
          (c) Distributions with Respect to Unexchanged Shares.  No dividends or
     other distributions declared or made after the Effective Time, with respect
     to Parent Common Shares with a record date after the Effective Time, shall
     be paid to the holder of any unsurrendered Certificate until the holder of
     such Certificate shall surrender such Certificate. Subject to applicable
     law, following surrender of any such Certificate, there shall be paid to
     the record holder of the certificates representing whole shares of Parent
     Common Shares issued in exchange therefor, without interest, at the time of
     such surrender, the amount of dividends or other distributions with a
     record date after the Effective Time theretofore paid with respect to such
     whole shares of Parent Common Shares.
 
          (d) Transfers of Ownership.  If any certificate for shares of Parent
     Common Shares is to be issued in a name other than that in which the
     Certificate surrendered in exchange therefor is registered, it will be a
     condition of the issuance thereof that the Certificate so surrendered will
     be properly endorsed and otherwise in proper form for transfer and that the
     person requesting such exchange will have paid to Parent or any person
     designated by it any transfer or other taxes required by reason of the
     issuance of a certificate for shares of Parent Common Shares in any name
     other than that of the registered holder of the certificate surrendered, or
     established to the satisfaction of Parent or any agent designated by it
     that such tax has been paid or is not payable.
 
          (e) No Liability.  Neither Parent, Merger Sub nor the Company shall be
     liable to any holder of Company Common Stock for any Merger Consideration
     (or dividends or distributions with respect thereto) delivered to a public
     official pursuant to any applicable abandoned property, escheat or similar
     law.
 
          (f) Withholding Rights.  Parent, the Surviving Corporation and the
     Exchange Agent shall be entitled to deduct and withhold from the Merger
     Consideration otherwise payable pursuant to this Agreement to any holder of
     Company Common Stock such amounts as Parent, the Surviving Corporation or
     the Exchange Agent is required to deduct and withhold with respect to the
     making of such payment under the Code or any provision of state, local,
     provincial or foreign tax law. To the extent that amounts are so withheld,
     such withheld amounts shall be treated for all purposes of this Agreement
     as having been paid to the holder of the Shares in respect of which such
     deduction and withholding was made by Parent or the Exchange Agent.
 
     SECTION 1.08. STOCK TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of the Company Common Stock thereafter on the records
of the Company.
 
     SECTION 1.09. DISSENTING SHARES.
 
          (a) Notwithstanding any provision of this Agreement to the contrary,
     any shares of capital stock of the Company held by a holder who has
     exercised dissenters' rights for such shares in accordance with Delaware
     Law and who, as of the Effective Time, has not effectively withdrawn or
     lost such dissenters' rights ("Dissenting Shares"), shall not be converted
     into or represent a right to receive Merger 
 
                                        4
   9

     Consideration pursuant to Section 1.06, but the holder thereof shall
     only be entitled to such rights as are granted by Delaware Law.
      
          (b) Notwithstanding the provisions of subsection (a), if any holder of
     Dissenting Shares shall effectively withdraw or lose (through failure to
     perfect or otherwise) such holder's dissenters' rights, then, as of the
     later of the Effective Time or the occurrence of such event, such holder's
     shares shall automatically be converted into and represent only the right
     to receive the Merger Consideration, without interest thereon, upon
     surrender of the certificate or certificates representing such Dissenting
     Shares.
 
          (c) The Company shall give Parent (i) prompt notice of any written
     demands received by the Company for an appraisal of shares of capital stock
     of the Company pursuant to Section 262 of Delaware Law, withdrawals of such
     demands, and any other related instruments served pursuant to Delaware Law
     and received by the Company and (ii) the opportunity to participate in all
     negotiations and proceedings with respect to such demands. The Company
     shall not, except with the prior written consent of Parent, voluntarily
     make any payment with respect to any such demands or offer to settle or
     settle any such demands.
 
     SECTION 1.10. NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  The
Merger Consideration delivered upon the surrender for exchange of Shares in
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Shares, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
Shares which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article I.
 
     SECTION 1.11. LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such Parent Common
Shares as may be required pursuant to Section 1.06; provided, however, that
Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Parent or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.
 
     SECTION 1.12. TAX AND ACCOUNTING CONSEQUENCES.  It is intended by the
parties hereto that the Merger shall (i) constitute a reorganization within the
meaning of Section 368 of the Code and (ii) qualify for accounting treatment as
a pooling of interests under GAAP. The parties hereto hereby adopt this
Agreement as a "plan of reorganization" within the meaning of Sections
1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations promulgated
under the Code.
 
     SECTION 1.13. TAKING OF NECESSARY ACTION; FURTHER ACTION.  Subject to the
terms and conditions herein, each of Parent, Merger Sub and the Company in good
faith will take all such commercially reasonable and lawful action as may be
necessary or appropriate in order to effectuate the Merger in accordance with
this Agreement as promptly as possible. If, at any time after the Effective
Time, any such further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Merger Sub, the officers and directors of the
Company and Merger Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.
 
     SECTION 1.14. MATERIAL ADVERSE EFFECT.  When used in this Agreement with
respect to the Company or any of its subsidiaries, or Parent or any of its
subsidiaries, as the case may be, the term "Material Adverse Effect" means any
change or effect that, individually or when taken together with all other such
changes or effects that have occurred prior to the date of determination of the
occurrence of the Material Adverse Effect, is or is reasonably likely to be
materially adverse to the business, assets (including intangible assets),
financial condition or results of operations of the Company and its subsidiaries
or Parent and its subsidiaries, as the case may be, in each case taken as a
whole; provided, however, that a Material Adverse Effect shall not include any
change or effect in respect of the Company and its subsidiaries or in respect of
Parent and its subsidiaries, as the case may be, resulting from conditions
affecting the semiconductor automatic test equipment industry generally or
general economic conditions.

                                   ARTICLE II
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     The Company hereby represents and warrants to Parent and Merger Sub that,
except as set forth in the written disclosure schedule previously delivered by
Company to Parent (the "Company Disclosure Schedule"):
 
     SECTION 2.01. ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each of the
Company and its subsidiaries is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation and
has the requisite corporate power and authority necessary to own, lease and
operate the properties it purports to own, operate or lease and to carry on its
business as it is now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power and authority
would not have a Material Adverse Effect. Each of the Company and its
subsidiaries is duly qualified or licensed as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character of
its properties owned, leased or operated by it or the nature of its activities
makes such qualification or licensing necessary, except for such failures to be
so duly qualified or licensed and in good standing that would not have a
Material Adverse Effect. A true and complete list of all of the Company's
subsidiaries, together with the jurisdiction of incorporation of each subsidiary
and the percentage of each subsidiary's outstanding capital stock owned by the
Company or another subsidiary, is set forth in Section 2.01 of the Company
Disclosure Schedule, except as is noted therein. Except as set forth in Section
2.01 of the Company Disclosure Schedule, the Company does not directly or
indirectly own any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for, any equity or similar interest in, any
corporation, partnership, joint venture or other business association or entity.
 
     SECTION 2.02. CERTIFICATE OF INCORPORATION AND BY-LAWS.  The Company has
heretofore furnished to Parent a complete and correct copy of its Certificate of
Incorporation and By-Laws, as amended to date, and, except as is set forth in
Section 2.02 of the Company Disclosure Schedule, equivalent organizational
documents of each of its subsidiaries (the "Subsidiary Documents"). Such
Certificate of Incorporation, By-Laws and equivalent organizational documents of
each of its subsidiaries are in full force and effect. Neither the Company nor
any of its subsidiaries is in violation of any of the provisions of its
Certificate of Incorporation or By-Laws or Subsidiary Documents except, in the
case of any subsidiary of the Company, to the extent any such violation would
not have a Material Adverse Effect.
 
     SECTION 2.03. CAPITALIZATION.  The authorized capital stock of the Company
consists of 20,000,000 shares of Company Common Stock and 5,000,000 shares of
the Company's Preferred Stock $.001 par value per share (the "Company Preferred
Stock"). As of August 26, 1995, (i) 7,422,462 shares of Company Common Stock
were issued and outstanding, all of which are validly issued, fully paid and
nonassessable, (ii) no shares of Company Common Stock were held by subsidiaries
of the Company, (iii) 1,546,119 shares of Company Common Stock were reserved for
future issuance pursuant to option grants under the Company Stock Option Plans,
(iv) 406,834 shares of Company Common Stock were reserved for future issuance
under the Company Stock Purchase Plan and (v) no shares of Company Preferred
Stock were issued and outstanding. No material change in such capitalization has
occurred between August 26, 1995 and the date hereof. For purposes hereof,
option exercises by optionholders of Company Common Stock in the ordinary course
of business and issuances of Company Common Stock under the 1992 Employee Stock
Purchase Plan pursuant to the terms of such plan shall not be deemed a material
change in the Company's capitalization. Except as set forth in this Section 2.03
or Section 2.11 hereof or in Section 2.03 or Section 2.11 of the Company
Disclosure Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
capital stock of the Company or any of its subsidiaries or obligating the
Company or any of its subsidiaries to issue or sell any shares of capital stock
of, or other equity interests in, the Company or any of its subsidiaries. All
shares of Company Common Stock subject to issuance as aforesaid, upon issuance
on the terms and conditions specified in the instruments pursuant to which they
are issuable, shall be duly authorized, validly issued, fully paid and
nonassessable. There are no obligations, contingent or otherwise, of the Company
or any of its subsidiaries to repurchase, redeem or otherwise acquire any shares
of Company capital stock or the capital stock of any subsidiary or to
 
                                        6
   11
 
provide funds to or make any investment (in the form of a loan, capital
contribution or otherwise) in any such subsidiary or any other entity other than
guarantees of bank obligations of subsidiaries entered into in the ordinary
course of business. All of the outstanding shares of capital stock of each of
the Company's subsidiaries are duly authorized, validly issued, fully paid and
nonassessable, and, other than directors' qualifying shares, all such shares are
owned by the Company or another subsidiary free and clear of all security
interests, liens, claims, pledges, agreements, limitations in the Company's
voting rights, charges or other encumbrances of any nature whatsoever.
 
     SECTION 2.04. AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by the Company
and the consummation by the Company of the transactions contemplated hereby have
been duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions so contemplated (other than the
approval and adoption of the Merger by the holders of at least a majority of the
outstanding shares of the Company Common Stock entitled to vote in accordance
with Delaware Law and the Company's Certificate of Incorporation and By-Laws).
The Board of Directors of the Company has determined that it is advisable and in
the best interest of the Company's stockholders for the Company to enter into a
business combination with Parent upon the terms and subject to the conditions of
this Agreement. This Agreement has been duly and validly executed and delivered
by the Company and, assuming the due authorization, execution and delivery by
Parent and Merger Sub, as applicable, constitutes the legal, valid and binding
obligation of the Company.

          (a) Section 2.05(a) of the Company Disclosure Schedule includes a list
     of (i) all material contracts of the Company and its subsidiaries and (ii)

     constitute a default (or an event that with notice or lapse of time or both
     would become a default), or impair the Company's or any of its
     subsidiaries' rights or alter the rights or obligations of any third party
     under, or give to others any rights of termination, amendment, acceleration
     or cancellation of, any Material Contract, or result in the creation of a
     lien or encumbrance on any of the properties or assets of the Company or
     any of its subsidiaries pursuant to, any note, bond, mortgage, indenture,
     contract, agreement, lease, license, permit, franchise or other instrument
     or obligation to which the Company or any of its subsidiaries is a party or
     by which the Company or any of its subsidiaries or its or any of their
     respective properties is bound or affected, except in any such case for any
     such breaches, defaults or other occurrences that would not individually or
     in the aggregate, have a Material Adverse Effect.
 
          (c) Except as set forth in Section 2.05(c) of the Company Disclosure
     Schedule, the execution and delivery of this Agreement by the Company does
     not, and the performance of this Agreement by the Company will not, require

     Act of 1933, as amended (the "Securities Act"), the Exchange Act, state
     securities laws ("Blue Sky Laws") and the pre-merger notification
     requirements of the Hart-Scott-

     Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and
     the filing and recordation of appropriate merger or other documents as
     required by Delaware Law and (ii) where the failure to obtain such
     consents, approvals, authorizations or permits, or to make such filings or
     notifications, would not prevent or delay consummation of the Merger, or
     otherwise prevent or delay the Company from performing its obligations
     under this Agreement, or would not otherwise have a Material Adverse
     Effect.
 
     SECTION 2.06. COMPLIANCE; PERMITS.
 
          (a) Neither the Company nor any of its subsidiaries is in conflict
     with, or in default or violation of, (i) to the Company's knowledge, any
     law, rule, regulation, order, judgment or decree applicable to the Company
     or any of its subsidiaries or by which its or any of their respective
     properties is bound or affected or (ii) any note, bond, mortgage,
     indenture, contract, agreement, lease, license, permit franchise or other
     instrument or obligation to which the Company or any of its subsidiaries is
     a party or by which the Company or any of its subsidiaries or its or any of
     their respective properties is bound or affected, except for any such
     conflicts, defaults or violations which, individually or in the aggregate,
     would in either such case not have a Material Adverse Effect.
 
          (b) To the Company's knowledge, the Company and its subsidiaries hold
     all permits, licenses, easements, variances, exemptions, consents,
     certificates, orders and approvals from governmental authorities which are
     material to the operation of the business of the Company and its
     subsidiaries taken as a whole (collectively, the "Company Permits"). The
     Company and its subsidiaries are in compliance with the terms of the
     Company Permits, except where the failure to so comply would not have a
     Material Adverse Effect.
 
     SECTION 2.07. SEC FILINGS; FINANCIAL STATEMENTS.
 
          (a) The Company has filed all forms, reports and documents required to
     be filed with the SEC since March 1, 1993 and has made available to Parent

     to all such reports and registration statements filed by the Company with
     the SEC (collectively, the "Company SEC Reports"). The Company SEC Reports
     (i) were prepared in accordance with the requirements of the Securities Act
     or 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 filing prior to the date of
     this Agreement, 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 therein or necessary in order to make the statements therein, in
     the light of the circumstances under which they were made, not misleading.
     None of the Company's subsidiaries is required to file any forms, reports
     or other documents with the SEC.
 
          (b) Each of the consolidated financial statements (including, in each

     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.
 
          (c) The Company has heretofore furnished to Parent a complete and
     correct copy of any amendments or modifications, which have not yet been

business, operations or financial condition of the Company and its subsidiaries
taken as a whole, except liabilities (a) adequately provided for in the
Company's audited balance sheet (including any related notes thereto) for the

     other party to, any of the Employee Plans; (iv) each Employee Plan intended
     to qualify under Section 401(a) of the Code is the subject of a favorable

     current plan years; (vi) with respect to each Employee Plan, no "reportable

     cause the appropriate governmental agency or authority to revoke, such

subsidiaries have good, marketable and defeasible title to all of their
properties and assets, free and clear of all liens, charges and encumbrances
except liens for taxes not yet due and payable and such liens or other
imperfections of title, if any, as do not materially detract from the value of
or interfere with the present use of the property affected thereby or which
would not, individually or in the aggregate, have a Material Adverse Effect; and
all leases pursuant to which the Company or any of its subsidiaries lease from
others material amounts of real or personal property are in good standing, valid
and effective in accordance with their respective terms, and there is not under
any of such leases, any existing material default or event of default on the
part of the Company (or event which with notice or lapse of time, or both, would
constitute a material default on the part of the Company and in respect of which
the Company or such subsidiary has not taken adequate steps to prevent such a
default from occurring) except where the lack of such good standing, validity
and effectiveness or the existence of such default or event of
 
                                       11
   16
 
default would not have a Material Adverse Effect. All the facilities of the
Company and its subsidiaries, except such as may be under construction, are in
good operating condition and repair, except where the failure of such plants,
structures and equipment to be in such good operating condition and repair would
not, individually or in the aggregate, have a Material Adverse Effect.
 
     SECTION 2.16. TAXES.
 
          (a) For purposes of this Agreement, "Tax" or "Taxes" shall mean taxes,
     fees, levies, duties, tariffs, imposts and governmental impositions or
     charges of any kind in the nature of (or similar to) taxes, payable to any
     federal, state, provincial, local or foreign taxing authority, including
     (without limitation) (i) income, franchise, profits, gross receipts, ad
     valorem, net worth, value added, sales, use, service, real or personal
     property, special assessments, capital stock, license, payroll,
     withholding, employment, social security, workers' compensation,
     unemployment compensation, utility, severance, production, excise, stamp,
     occupation, premiums, windfall profits, transfer and gains taxes and (ii)
     interest, penalties, additional taxes and additions to tax imposed with
     respect thereto; and "Tax Returns" shall mean returns, reports and
     information statements with respect to Taxes required to be filed with the
     United States Internal Revenue Service (the "IRS") or any other taxing
     authority, domestic or foreign, including, without limitation,

          (b) Other than as disclosed on Section 2.16(b) of the Company
     Disclosure Schedule, the Company and each of its subsidiaries, and any
     consolidated, combined, unitary or aggregate group for Tax purposes of
     which the Company or any of its subsidiaries is or has been a member, have
     filed all United States federal income Tax Returns and all other material
     Tax Returns required to be filed by them or any of them, and have paid and
     discharged all Taxes shown therein to be due and there are no other Taxes
     that would be due if asserted by a taxing authority, except such as are
     being contested in good faith by appropriate proceedings (to the extent
     that any such proceedings are required) or with respect to which the
     Company is maintaining reserves in accordance with GAAP in its financial
     statements to the extent currently required in all material respects
     adequate for their payment, except, in each instance, to the extent the
     failure to do so would not have a Material Adverse Effect. Neither the IRS
     nor any other taxing authority or agency is now asserting or, to the best
     of the Company's knowledge, threatening to assert against the Company or
     any of its subsidiaries any deficiency or claim for additional Taxes other
     than additional Taxes with respect to which the Company is maintaining
     reserves in accordance with GAAP in its financial statements which are in
     all material respects adequate for their payment, except, in each instance,
     to the extent the failure to do so would not have a Material Adverse
     Effect. No Tax Return of either the Company or any of its subsidiaries is
     currently being audited by any taxing authority. No material tax claim has
     become a lien on any assets of the Company or any subsidiary thereof and
     neither the Company nor any of its subsidiaries has granted any waiver of
     any statute of limitations with respect to, or any extension of a period
     for the assessment of, any Tax.
 
          (c) The Company on behalf of itself and all its subsidiaries hereby
     represents that, other than as disclosed on Section 2.16(c) of the Company
     Disclosure Schedule, and other than with respect to items the inaccuracy of
     which would not have a Material Adverse Effect: (i) neither the Company nor
     any of its subsidiaries is a party to any agreement, contract or
     arrangement that may result, separately or in the aggregate, in the payment
     of (a) any "excess parachute payment" within the meaning of Section 28OG of
     the Code, determined without regard to Section 28OG(b)(4) of the Code or
     (b) any amount that would not be deductible by the Parent or the Company

     subsidiaries has been subject to any accumulated earning tax or personal

     meaning of Section 1296 of the Code; (iv) neither the Company nor any of

     contemplated hereunder; (v) neither the Company nor any of its subsidiaries
     has entered into any deferred intercompany transaction within the meaning
     of Section 1.1502-13(a)(2) of the United States
 
                                       12
   17
 
     Treasury Regulations promulgated under the Code as to which material items
     of deferred gain or loss have not been restored; and (vi) no material
     excess loss account within the meaning of Section 1.1502-32 and -19 of the
     United States Treasury Regulations promulgated under the Code exists with
     respect to the stock of any of the Company's subsidiaries; (vi) neither the
     Company nor any of its Subsidiaries has filed a consent under Section
     341(f) concerning collapsible corporations; (vii) neither the Company nor
     any of its subsidiaries has been a United States real property holding
     corporation within the meaning of Section 897(c)(2) of the Code; (viii)
     neither the Company nor any of its subsidiaries has any liability for the
     Taxes of another person (other than any of the Company and its
     subsidiaries) under Section 1.1502-6 of the United States Treasury
     Regulations promulgated under the Code (or any similar provision of state,
     local or foreign law), as a transferee or successor, by contract, or
     otherwise.
 
          (d) No power of attorney has been granted by the Company or any of its
     subsidiaries with respect to any matter relating to Taxes which is
     currently in force.
 
          (e) Neither the Company nor any of its subsidiaries is a party to any
     agreement or arrangement (written or oral) providing for the allocation or
     sharing of Taxes.
 
          (f) The Company and each of its subsidiaries have withheld from each
     payment made to any of their respective past or present employees, officers
     or directors the amount of all Taxes and other deductions required to be
     withheld therefrom and paid the same to the proper tax or other receiving
     officers within the time required by law, except to the extent that any
     failure to do so would not have a Material Adverse Effect.
 
          (g) The Company has remitted to the appropriate Tax authority when
     required by law to do so all amounts collected by it on account of all
     retail sales Tax, except to the extent that any failure to do so would not
     have a Material Adverse Effect.
 
          (h) There has been no material debt to a third party of the Company or
     any of its subsidiaries which has been forgiven and which has given rise to
     (or is expected to give rise to) "cancellation of indebtedness income"
     under the provisions of the Code.
 
     SECTION 2.17. ENVIRONMENTAL MATTERS.  Except in all cases, in the
aggregate, as have not had and could not reasonably be expected to have a
Material Adverse Effect, to the Company's knowledge, the Company and each of its
subsidiaries (i) have obtained all applicable permits, licenses and other
authorizations which are required under federal, state, provincial or local laws

or proceeding, based on or resulting from the Company's or any of its
subsidiary's (or any of their respective agent's) manufacture, processing,
distribution, use, treatment, storage, disposal, transport or handling, or the

     code form) and tangible or intangible proprietary information or material
     that are used or proposed to be used in the business of the Company as

     2.20(a) of the Company Disclosure Schedule lists all current patents,

     registered and material unregistered copyrights, trade names and any
     applications therefor owned by the Company (the "Company Intellectual

     in Section 2.20(a) of the Company Disclosure Schedule, which violation
     would have a Material Adverse Effect. No claims with respect to the Company
     Intellectual Property Rights, any trade secret material to the Company, or
     Third Party Intellectual Property Rights to the extent arising out of any
     use, reproduction or distribution of such Third Party Intellectual Property
     Rights by or through the Company, are currently pending or, to the
     knowledge of the Company, are threatened by any person; nor does the
     Company know of any valid grounds for any bona fide claims (i) to the
     effect that the manufacture, sale, licensing or use of any product as so
     used, sold or licensed or proposed for use, sale or license by the Company
     infringes on any copyright, patent, trademark, service mark or trade secret
     of any other person; (ii) against the use by the Company of any trademarks,
     trade names, trade secrets, copyrights, patents, technology, know-how or
 
                                       14

     by the Company are valid and subsisting. Except as set forth in Section
     2.20(b) of the Company Disclosure Schedule, to the Company's knowledge,
     there is no unauthorized use, infringement or misappropriation of any of
     the Company Intellectual Property Rights by any third party, including any
     employee or former employee of the Company or any of its subsidiaries,
     which use, infringement or misappropriation would have a Material Adverse
     Effect. Neither the Company nor any of its subsidiaries (i) has been sued
     or charged in writing as a defendant in any claim, suit, action or

     informed or notified by any third party in writing that the Company may be
     engaged in such infringement or (iii) has knowledge of any infringement
     liability with respect to, or infringement by, the Company or any of its
     subsidiaries of any trade secret, patent, trademark, service mark, maskwork
     or copyright of another, which infringement would have a Material Adverse
     Effect.

     information concerning the Company has executed a confidentiality and
     invention agreement in the forms previously delivered to Parent.

or any of its subsidiaries pending under any of such policies or bonds as to
which coverage has been questioned, denied or disputed by the underwriters of
such policies or bonds. All premiums payable under all such policies and bonds
have been paid and the Company and its subsidiaries are otherwise in full
compliance with the terms of such policies and bonds (or other policies and
bonds providing substantially similar insurance coverage in all material
respects). The Company does not know of any threatened termination of, or
material premium increase with respect to, any of such policies.

     SECTION 2.25. POOLING MATTERS.  To the Company's knowledge and based upon
consultation with its independent accountants, neither the Company nor any of
its affiliates has taken or agreed to take any action that would affect the
ability of Parent to account for the business combination to be effected by the
Merger as a pooling of interests. The Company has received from Price Waterhouse
LLP a written opinion addressed to it and Parent to the effect that the Merger
qualifies for a pooling of interests accounting treatment if consummated in
accordance with this Agreement.
 
     SECTION 2.26. OPINION OF FINANCIAL ADVISOR.  The Company has been advised
by its financial advisor, Montgomery Securities, that in its opinion, as of the

the failure to be so organized, existing and in good standing or to have such
power, authority and Approvals would not have a Material Adverse Effect. Parent
and each of its subsidiaries is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would not
have a Material Adverse Effect.
 
     SECTION 3.02. AUTHORITY RELATIVE TO THIS AGREEMENT.  Each of Parent and
Merger Sub has all necessary corporate power and authority to execute and
deliver this Agreement and to perform its obligations hereunder and to
consummate the transactions contemplated hereby. The execution and delivery of
this Agreement by Parent and Merger Sub and the consummation by Parent and
Merger Sub of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action on the part of Parent and Merger
Sub, and no other corporate proceedings on the part of Parent or Merger Sub are
necessary to authorize this Agreement or to consummate the transactions so
contemplated. The Board of Directors of Parent has determined that it is
advisable and in the best interest of Parent's stockholders for Parent to enter
into a business combination with the Company upon the terms and subject to the
conditions of this Agreement. This Agreement has been duly and validly executed
and delivered by Parent and Merger Sub and, assuming the due authorization,
execution and delivery by the Company, constitutes a legal, valid and binding
obligation of Parent and Merger Sub.
 
     SECTION 3.03. NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a) The
execution and delivery of this Agreement by Parent and Merger Sub do not, and
the performance of this Agreement by Parent and Merger Sub shall not, (i)
conflict with or violate the Articles of Organization or By-Laws of Parent or
the Certificate of Incorporation or By-Laws of Merger Sub, (ii) conflict with or
violate any law, rule, regulation, order, judgment or decree applicable to
Parent or any of it subsidiaries or by which its or their respective properties
are bound or affected, or (iii) result in any breach of or constitute a default
(or an event which with notice or lapse of time or both would become a default)
under, or impair Parent's rights or alter the rights or obligations of any third
party under, or give to others any rights of termination, amendment,
acceleration or cancellation of, any Material Contract or result in the creation
of a lien or encumbrance on any of the properties or assets of Parent or any of
its subsidiaries pursuant to, any material note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Parent or any of its subsidiaries is a party or by which
Parent or any of its subsidiaries or its or any of their respective properties
are bound or affected, except in any such case for any such breaches, defaults
or other occurrences that would not have a Material Adverse Effect.
 
          (b) The execution and delivery of this Agreement by Parent and Merger
     Sub will not require any consent, approval, authorization or permit of, or
     filing with or notification to, any governmental or regulatory authority,
     domestic or foreign, except (i) for applicable requirements, if any, of the
     Securities Act, the Exchange Act, the NYSE, the Blue Sky Laws and the
     pre-merger notification requirements of the HSR Act and (ii) where the
     failure to obtain such consents, approvals, authorizations or permits, or
 
                                       16
   21
 
     to make such filings or notifications, would not prevent or delay
     consummation of the Merger, or otherwise prevent Parent or Merger Sub from
     performing their respective obligations under this Agreement, and would not
     have a Material Adverse Effect.
 
     SECTION 3.04. ARTICLES OF ORGANIZATION AND BY-LAWS.  Parent has heretofore
furnished to the Company a complete and correct copy of its Articles of
Organization and the By-Laws, as amended to date. Such Articles of Organization
and By-Laws are in full force and effect. Neither Parent nor Merger Sub is in
violation of any of the provisions of its Certificate of Incorporation or
By-Laws.
 
     SECTION 3.05. CAPITALIZATION.  As of June 30, 1995, the authorized capital
stock of Parent consisted of 75,000,000 Parent Common Shares of which:
37,610,648 shares were issued and outstanding, 1,575,008 shares were held in
treasury, 5,677,973 shares were reserved for issuance pursuant to outstanding
options under Parent's stock option plans, and 560,640 shares were reserved for
future issuance under Parent's employee purchase plan. No material change in
such capitalization has occurred between June 30, 1995 and the date hereof
except that (A) on July 24, 1995, Parent declared a two-for-one stock split in
the form of a stock dividend on its issued and outstanding Parent Common Shares
payable to holders of record on August 8, 1995 and (B) on July 17, 1995, Parent
amended its Articles of Organization to increase its authorized capital stock
from 75,000,000 Parent Common Shares to 125,000,000 Parent Common Shares. Except
as set forth in this Section 3.05, there are no options, warrants or other
rights, agreements, arrangements or commitments of any character relating to the
issued or unissued capital stock of Parent or any of its subsidiaries or
obligating Parent or any of its subsidiaries to issue or sell any shares of
capital stock of, or other equity interests in, Parent or any of its
subsidiaries. The authorized capital stock of Merger Sub consists of 1,000
shares of common stock, par value $0.001 per share, 100 shares of which, as of
the date hereof, are issued and outstanding. All of the outstanding shares of
Parent's and Merger Sub's respective capital stock have been duly authorized and
validly existing and are fully paid and nonassessable. Parent owns all of the
capital stock of Merger Sub. The Parent is party to a Rights Agreement (the
"Rights Agreement") dated as of March 14, 1990, a copy of which has been
provided to the Company. Parent represents and warrants that since March 14,
1990 there has not occurred an event which has caused the rights issuable under
the Rights Agreement to separate from the Parent Common Shares.

bound or affected or (ii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which Parent or any of its subsidiaries is a party or by which Parent or any

affected, except for any such conflicts, defaults or violations which would not
have a Material Adverse Effect.
 
          (b) Parent and its subsidiaries hold all permits, licenses, easements,
     variances, exemptions, consents, certificates, orders and approvals from
     governmental authorities which are material to the operation of the
     business of the Company and its subsidiaries taken as a whole as it is now
     being conducted (collectively, the "Parent Permits"). Parent and its
     subsidiaries are in compliance with the terms of the Parent Permits, except
     where the failure to so comply would not have a Material Adverse Effect.
 
     SECTION 3.07. SEC FILINGS, FINANCIAL STATEMENTS.  (a) Parent has filed all
forms, reports and documents required to be filed with the SEC since December
31, 1992, and has heretofore delivered to the Company, in the form filed with
the SEC, (i) its Annual Reports on Form 10-K for the fiscal years ended December
31, 1993 and 1994 and its quarterly report on Form 10-Q for the fiscal quarters

Parent's meetings of stockholders (whether annual or special) held since
December 31, 1994, (iii) all other reports or registration statements (other

                                       17
   22
 
and (ii) did not at the time they were filed (or if amended or superseded by a
filing prior to the date of this Agreement, 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 therein or necessary in order to make the statements
therein, 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.
 
          (b) Each of the consolidated financial statements (including, in each
     case, any related notes thereto) contained in the Parent SEC Reports has
     been prepared in accordance with GAAP applied on a consistent basis
     throughout the periods involved (except as may be indicated in the notes
     thereto) and each fairly presents the consolidated financial position of
     Parent and its subsidiaries as at the respective dates thereof 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.
 
          (c) Parent has heretofore furnished to the Company a complete and
     correct copy of any amendments or modifications, which have not yet been
     filed with the SEC but which are required to be filed, to agreements,

     Exchange Act and the SEC's rules thereunder as "material contracts" of the
     Parent and its subsidiaries.
 
     SECTION 3.08. ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth in
Section 3.08 of the Parent Disclosure Schedule, since December 31, 1994, Parent
has conducted its business in the ordinary course and there has not occurred:
(i) any Material Adverse Effect; (ii) any amendments or changes in the Articles
of Organization or By-Laws of Parent; (iii) any damage to, destruction or loss
of any assets of the Parent (whether or not covered by insurance) that could
have a Material Adverse Effect; (iv) any revaluation by Parent of any of its
assets, including, without limitation, writing down the value of capitalized
software or inventory or writing off notes or accounts receivable other than in
the ordinary course of business; or (v) except as disclosed in Section 3.08 of
the Parent Disclosure Schedule, any other action or event that would have
required the consent of the Company pursuant to Section 4.03 had such action or
event occurred after the date of this Agreement.
 
     SECTION 3.09. RESTRICTIONS ON BUSINESS ACTIVITIES.  Except for this
Agreement, there is no material agreement, judgment, injunction, order or decree
binding upon Parent or any of its subsidiaries which has or could reasonably be
expected to have the effect of prohibiting or materially impairing any business
practice of Parent or any of its subsidiaries, any acquisition of property by
Parent or any of its subsidiaries or the conduct of business by Parent or any of
its subsidiaries as currently conducted or as proposed to be conducted by
Parent.
 
     SECTION 3.10. TITLE TO PROPERTY.  Parent and each of its subsidiaries have
good, marketable and defensible title to all of their properties and assets,
free and clear of all liens, charges and encumbrances except liens for taxes not
yet due and payable and such liens or other imperfections of title, if any, as
do not materially detract from the value of or interfere with the present use of
the property affected thereby or which would not have a Material Adverse Effect;
and, to Parent's knowledge, all leases pursuant to which Parent or any of its
subsidiaries lease from others material amounts of real or personal property are
in good standing, valid and effective in accordance with their respective terms,
and there is not, to the knowledge of Parent, under any of such leases, any
existing material default or event of default (or event which, with notice or
lapse of time, or both, would constitute a material default and in respect of
which Parent or such subsidiary has not taken adequate steps to prevent such a
default from occurring) except where the lack of such good standing, validity
and effectiveness, or the existence of such default or event of default would
not have a Material Adverse Effect.
 
                                       18
   23
 
     SECTION 3.11. FULL DISCLOSURE.  No statement contained in any certificate
or schedule furnished or to be furnished by Parent or Merger Sub to the Company
in, or pursuant to the provisions of, this Agreement contains or will contain
any untrue statement of a material fact or omits or shall omit to state any
material fact necessary, in the light of the circumstances under which it was
made and based upon the facts and circumstances existing at the time it was
made, to make the statements herein or therein not misleading.
 
     SECTION 3.12. NO UNDISCLOSED LIABILITIES.
 
          (a) Except as is disclosed in the Parent SEC Reports, neither Parent
     nor any of its subsidiaries has any liabilities (absolute, accrued,
     contingent or otherwise) which are, in the aggregate, material to the
     business, operations or financial condition of Parent and its subsidiaries
     taken as a whole, except liabilities (i) adequately provided for in
     Parent's balance sheet (including any related notes thereto) as of December
     31, 1994 included in the Parent SEC Reports (the "December 31 Balance
     Sheet"), (ii) incurred in the ordinary course of business and not required
     under GAAP to be reflected on the December 31 Balance Sheet, or (iii)
     incurred since December 31, 1994 in the ordinary course of business and
     consistent with past practice, and liabilities incurred in connection with
     this Agreement.
 
          (b) As of the date hereof and the Effective Time, except for
     obligations or liabilities incurred in connection with its incorporation or
     organization and the transactions contemplated by this Agreement and except
     for this Agreement and any other agreements or arrangements contemplated by
     this Agreement, Merger Sub has not and will not have incurred, directly or
     indirectly, through any subsidiary or affiliate, any obligations or
     liabilities or engaged in any business activities of any type or kind
     whatsoever or entered into any agreements or arrangements with any person.
 
     SECTION 3.13. ABSENCE OF LITIGATION.  Except as set forth in Section 3.13
of the Parent Disclosure Schedule or as reflected in the Parent SEC Reports,
there are no claims, actions, suits, proceedings or investigations pending or,
to the knowledge of Parent, threatened against Parent or any of its
subsidiaries, or any properties or rights of Parent or any of its subsidiaries,
before any court, arbitrator or administrative, governmental or regulatory
authority or body, domestic or foreign, that could have a Material Adverse
Effect.
 
     SECTION 3.14. INSURANCE.  Parent and its subsidiaries maintain fire and
casualty, general liability, business interruption, product liability and
sprinkler and water damage insurance that Parent believes to be reasonably
prudent for its business.
 
     SECTION 3.15. REGISTRATION STATEMENT; PROXY STATEMENT; PROSPECTUS.  Subject
to the accuracy of the representations of the Company in Section 2.13, the
Registration Statement pursuant to which the Parent Common Shares to be issued
in the Merger will be registered with the SEC shall not, at the time the
Registration Statement (including any amendments or supplements thereto) is
declared effective by the SEC, contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
included therein, in light of the circumstances under which they were made, not
misleading. Subject to the accuracy of the representations of the Company in
Section 2.13, the information supplied by Parent for inclusion in the Proxy
Statement/Prospectus will not, on the date the Proxy Statement/Prospectus is
first mailed to stockholders, at the time of the Company Stockholders Meeting
and at the Effective Time, contain any statement which, at such time and in
light of the circumstances under which it shall be made, is false or misleading
with respect to any material fact, or will omit to state any material fact
necessary in order to make the statements therein not false or misleading. The
Registration Statement will comply as to form in all material respects with the
applicable provisions of the Securities Act and the rules and regulations
promulgated thereunder. If at any time prior to the Effective Time any event
relating to Parent, Merger Sub or any of their respective affiliates, officers
or directors should be discovered by Parent or Merger Sub which should be set
forth in an amendment to the Registration Statement or a supplement to the Proxy
Statement/ Prospectus, Parent or Merger Sub will promptly inform the Company.
Notwithstanding the foregoing, Parent makes no representation or warranty with
respect to any information supplied, by the Company which is contained in, or
furnished in connection with the preparation of, any of the foregoing.
 
     SECTION 3.16. TAXES.  Parent and each of its subsidiaries, and any
consolidated, combined, unitary or aggregate group for Tax purposes of which
Parent or any of its subsidiaries is or has been a member, have filed
 
                                       19
   24
 
all United States federal income Tax Returns and all other material Tax Returns
required to be filed by them or any of them, and have paid and discharged all
Taxes shown therein to be due and there are no other Taxes that would be due if
asserted by a taxing authority, except such as are being contested in good faith
by appropriate proceedings (to the extent that any such proceedings are
required) or with respect to which Parent is maintaining reserves in accordance
with GAAP in its financial statements to the extent currently required in all
material respects adequate for their payment, except, in each instance, to the
extent the failure to do so would not have a Material Adverse Effect. Neither
the IRS nor any other taxing authority or agency is now asserting or, to the
best of Parent's knowledge, threatening to assert against Parent or any of its
subsidiaries any deficiency or claim for additional Taxes other than additional
Taxes with respect to which Parent is maintaining reserves in accordance with
GAAP in its financial statements which are in all material respects adequate for
their payment, except, in each instance, to the extent that the failure to do so
would not have a Material Adverse Effect. No Tax Return of either Parent or any
of its subsidiaries is currently being audited by any taxing authority except as
would not have a Material Adverse Effect. No material tax claim has become a
lien on any assets of Parent or any subsidiary thereof and neither Parent nor
any of its subsidiaries has, except as would not have a Material Adverse Effect,
granted any waiver of any statute of limitations with respect to, or any
extension of a period for the assessment of, any Tax.

commission in connection with the transactions contemplated by this Agreement
based upon arrangements made by or on behalf of Parent or Merger Sub.
 
     SECTION 3.18. OPINION OF FINANCIAL ADVISOR.  Parent has been advised by its
financial advisor, S.G. Warburg & Co. Inc., that in its opinion, as of the date
hereof, the Exchange Ratio is fair from a financial point of view to Parent, and
Parent has delivered a copy of such opinion to the Company.
 
     SECTION 3.19. POOLING MATTERS.  Neither Parent nor any of its affiliates,
to its knowledge and based upon consultation with its independent accountants,
is aware of any fact or has taken or agreed to take any action that (without
giving effect to any action taken or agreed to be taken by the Company or any of
its affiliates) would affect the ability of Parent to account for the business
combination to be effected by the Mergers as a pooling of interests. Parent has
received from Coopers & Lybrand LLP an opinion addressed to it and the Company
to the effect that the Merger qualifies for a pooling of interests accounting
treatment consummated in accordance with this agreement.
 
     SECTION 3.20. NO STOCKHOLDER VOTE.  No vote of the stockholders of Parent
is necessary to approve the Merger or the issuance of Parent Common Shares
therein.

     controlled group including the Parent or which is under common control with
     the Parent (a "Parent ERISA Affiliate") within the meaning of Section 414
     of the Code, or any subsidiary of the Parent, to which the Parent, a Parent
     ERISA Affiliate, or any subsidiary is a party, with respect to which the
     Parent, a Parent ERISA Affiliate, or any subsidiary has or could have any
     obligation, as well as each plan with respect to which the Parent or a
     Parent ERISA Affiliate could incur liability if such plan has been or were
     terminated (together, the "Parent Employee Plans") that is required or
     intended to be qualified under applicable law or registered or approved by
     a governmental agency or authority, has been so qualified, registered or
     approved by the appropriate governmental agency or authority, and nothing
     has occurred since the date of the last qualification, registration or
     approval to adversely affect, or cause the appropriate governmental agency
     or authority to revoke, such qualification, registration or approval.

     Parent (or their beneficiaries) with respect to the Parent Employee Plans
     or the assets or fiduciaries thereof (other than routine claims for
     benefits).
 
          (e) To the Parent's knowledge, no condition or event has occurred with
     respect to the Parent Employee Plans which has or could reasonably be
     expected to result in a Material Adverse Effect to the Parent.
 
     SECTION 3.22. LABOR MATTERS.  There are no controversies pending or, to the
knowledge of the Parent or any of its subsidiaries, threatened, between the
Parent or any of its subsidiaries and any of their respective employees, which
controversies have or could reasonably be expected to have a Material Adverse
Effect; neither the Parent nor any of its subsidiaries is a party to any

or statutory liability, or otherwise form the basis of any claim, action, suit
or proceeding, based on or resulting from the Parent's or any of its

     SECTION 3.24. INTELLECTUAL PROPERTY.
 
          (a) The Parent owns, or is licensed or otherwise possesses legally
     sufficient rights to use, all patents, trademarks, trade names, service
     marks, copyrights and any applications therefor, technology, know-how,
     computer software programs or applications (in both source code and object
     code form) and tangible or intangible proprietary information or material
     that are used or proposed to be used in the business of the Parent as
     currently conducted (the "Parent Intellectual Property Rights"), except
     where the failure to own or to license or posses such rights would not have
     a Material Adverse Affect. No claims with respect to the Parent
     Intellectual Property Rights, any trade secret material to the Parent, or
     third party patents,
 
                                       21
   26
 
     trademarks, or copyrights (including software) (the "Parent Third Party
     Intellectual Property Rights") to the extent arising out of any use,
     reproduction or distribution of such Parent Third Party Intellectual
     Property Rights by or through the Parent, are currently pending or, to the
     knowledge of the Parent, are threatened by any person which claims would,
     if resolved adversely to Parent, have a Material Adverse Affect, nor does
     the Parent know of any valid grounds for any bona fide claims (i) to the
     effect that the manufacture, sale, licensing or use of any product as so
     used, sold or licensed or proposed for use, sale or license by the Parent
     infringes on any copyright, patent, trademark, service mark or trade secret
     of any other person; (ii) against the use by the Parent of any trademarks,

     or other trade secret material to the Parent; or (iv) challenging the

     subsidiaries (i) has been sued or charged in writing as a defendant in any

     service mark, maskwork or copyright of another, which infringement would
     have a Material Adverse Effect.
 
          (b) Each employee of the Parent with access to confidential
     information concerning the Parent has executed a confidentiality and

          (n) take, or agree in writing or otherwise to take, any of the actions

     this Agreement untrue or in any material respect incorrect or prevent the
     Company from performing in any material respect or cause the Company not to
     perform in any material respect its covenants hereunder or result in any of
     the conditions to the Merger set forth herein not being satisfied.
 
     SECTION 4.02. NO SOLICITATION.  (a) The Company shall not, directly or
indirectly, through any officer, director, employee, representative or agent of
the Company or any of its subsidiaries, solicit or encourage (including by way
of furnishing information) the initiation or submission of any inquiries,
proposals or offers regarding any acquisition, merger, take-over bid, sale of
all or substantially all of its assets, sale of shares of capital stock
(including without limitation by way of a tender offer) representing more than
15% of the voting securities of the Company or similar transactions involving
the Company or any subsidiaries of the Company (any of the foregoing inquiries
or proposals being referred to herein as an "Acquisition Proposal"); provided,
however, that nothing contained in this Agreement shall prevent the Board of
Directors of the Company from referring any third party to this Section 4.02(a)
or providing a copy of this Agreement to any third party. Nothing contained in
this Section 4.02(a) or any other provision of this Agreement shall prevent the
Board of Directors of the Company from considering, negotiating, approving and
recommending to the stockholders of the Company an unsolicited bona fide written
Acquisition Proposal which the Board of Directors of the Company determines in
good faith (after consultation with its financial advisors and after
consultation with outside counsel as to whether the Board of Directors is
required to do so in order to discharge properly its fiduciary duties to
stockholders under applicable law) would result in a transaction more favorable
to the Company's stockholders from a financial point of view than the
transaction contemplated by this Agreement (any such Acquisition Proposal being
referred to herein as a "Superior Proposal").
 
          (b) The Company shall immediately notify Parent after receipt of any
     Acquisition Proposal or any request for nonpublic information relating to
     the Company or any of its subsidiaries in connection with an Acquisition
     Proposal or for access to the properties, books or records of the Company
     or any subsidiary by any person or entity that informs the Board of
     Directors of the Company or such subsidiary that it is considering making,
     or has made, an Acquisition Proposal. Such notice to Parent shall be made
     orally and in writing and shall indicate in reasonable detail the identity
     of the offeror and the terms and conditions of such proposal, inquiry or
     contact.
 
          (c) If the Board of Directors of the Company receives a request for
     material nonpublic information by a party who makes, or who states in
     writing that it intends, subject to satisfactory review of such nonpublic
     information, to make, a bona fide Acquisition Proposal and the Board of
     Directors of the Company determines that such proposal, if consummated
     pursuant to its terms, would be a Superior Proposal, then, and only in such
     case, the Company may, subject to the execution of a confidentiality and
 
                                       24
   29
 
     standstill agreement substantially similar to that then in effect between
     the Company and Parent, provide such party with access to information
     regarding the Company.
 
          (d) Subject to the second sentence of Section 4.02(a), the Company
     shall immediately cease and cause to be terminated any existing discussions
     or negotiations with any parties (other than Parent and Merger Sub)
     conducted heretofore with respect to any of the foregoing. The Company
     agrees not to release any third party from any confidentiality or
     standstill agreement to which the Company is a party.
 
          (e) The Company shall ensure that the officers, directors and
     employees of the Company and its subsidiaries and any investment banker or
     other advisor or representative retained by the Company are aware of the
     restrictions described in this Section, and shall be responsible for any
     breach of this Section 4.02 by such bankers, advisors and representatives.
 
          (f) Nothing contained in this Section 4.02 shall prevent the Company
     from complying with Rule 14e-2(a) or Rule 14d-9 promulgated under the
     Exchange Act with regard to an Acquisition Proposal.
 
     SECTION 4.03. CONDUCT OF BUSINESS BY PARENT PENDING THE MERGER.  During the
period from the date of this Agreement and continuing until the earlier of the
termination of this Agreement or the Effective Time, Parent covenants and agrees
that, unless the Company shall otherwise agree in writing, Parent shall conduct
its business, and cause the businesses of its subsidiaries to be conducted, in
the ordinary course of business and consistent with past practice, other than
actions taken by Parent or its subsidiaries in contemplation of the Merger, and
shall not directly or indirectly do, or propose to do, any of the following
without the prior written consent of the Company:
 
          (a) amend or otherwise change Parent's Articles of Organization, or
     amend the terms of the Parent Common Shares;
 
          (b) acquire or agree to acquire, by merging or consolidating with, by
     purchasing an equity interest in or a portion of the assets of, or by any
     other manner, any business or any corporation, partnership, association or
     other business organization or division thereof, or otherwise acquire or
     agree to acquire any assets of any other person, which, in each case, would
     materially delay or prevent the consummation of the transactions
     contemplated by this Agreement;
 
          (c) declare, set aside, make or pay any dividend or other distribution
     (whether in cash, stock or property or any combination thereof) in respect
     of any of its capital stock, except that a wholly owned subsidiary of
     Parent may declare and pay a dividend to its parent;
 
          (d) sell, transfer, license, sublicense or otherwise dispose of any
     material assets;
 
          (e) take or allow to be taken or fail to take any act or omission
     within the control of Parent or Merger Sub which would reasonably be
     expected to jeopardize the treatment of the Merger as a pooling of
     interests for accounting purposes under GAAP; or
 
          (f) take, or agree in writing or otherwise to take, any of the actions
     described in Sections 4.03(a) through (e) above, or any action which would
     make any of the representations or warranties of Parent contained in this
     Agreement untrue or incorrect in any material respect or prevent Parent
     from performing in any material respect or cause Parent not to perform in
     any material respect its covenants hereunder or result in any of the
     conditions of the Merger not being satisfied.

     SECTION 5.01. PROXY STATEMENT/PROSPECTUS; REGISTRATION STATEMENT.  As
promptly as practicable after the execution of this Agreement, the Company and
Parent shall prepare and file with the SEC preliminary proxy materials which
shall constitute the Proxy Statement of the Company and the Registration
Statement of Parent with respect to the Parent Common Shares to be issued in
connection with the Merger. As promptly as practicable after comments are
received from the SEC thereon and after the furnishing by the Company and Parent
of all information required to be contained therein, the Company and Parent
shall file with the SEC a combined proxy and registration statement on Form S-4
(or on such other form as shall be appropriate) relating to the approval of the
Merger and the transactions contemplated hereby by the stockholders of the
Company and shall use all reasonable efforts to cause the Registration Statement
to become effective as soon thereafter as practicable. The Proxy Statement shall
include the recommendation of the Board of Directors of the Company in favor of
the Merger, subject to the second sentence of Section 4.02.
 
     SECTION 5.02. STOCKHOLDERS MEETING.  The Company shall in accordance with
Delaware Law and the Company's Certificate of Incorporation and Bylaws call and
hold the Company Stockholders Meeting as promptly as practicable for the purpose
of voting upon the approval of the Merger. Subject to the second sentence of
Section 4.02, the Company shall use its reasonable best efforts to hold the
Company Stockholders Meeting as soon as practicable after the date on which the
Registration Statement becomes effective. Subject to the second sentence of
Section 4.02, the Company shall use its reasonable best efforts to solicit from
its respective stockholders proxies in favor of the approval of the Merger, and
shall take all other action necessary or advisable to secure the vote or consent
of stockholders required by Delaware Law to obtain such approvals.
 
     SECTION 5.03. ACCESS TO INFORMATION; CONFIDENTIALITY.  Upon reasonable
notice and subject to restrictions contained in confidentiality agreements to
which such party is subject, the Company and Parent shall each (and shall cause
each of their subsidiaries to) afford to the officers, employees, accountants,
counsel and other representatives of the other, reasonable access, during the
period prior to the Effective Time, to all its properties, books, contracts,
commitments and records and, during such period, the Company and Parent each
shall (and shall cause each of their subsidiaries to) furnish promptly to the
other all information concerning its business, properties and personnel as such
other party may reasonably request, and each shall make available to the other
the appropriate individuals (including attorneys, accountants and other
professionals) for discussion of the other's business, properties and personnel
as either party may reasonably request. Each party shall keep such information
confidential in accordance with the terms of the currently effective
confidentiality agreement dated August 16, 1995 (the "Confidentiality
Agreement") between Parent and the Company.
 
     SECTION 5.04. CONSENTS; APPROVALS.  The Company and Parent shall each use
their best efforts to obtain all consents, waivers, approvals, authorizations or
orders (including, without limitation, all United States and foreign
governmental and regulatory rulings and approvals), and the Company and Parent
shall make all filings (including, without limitation, all filings with United
States and foreign governmental or regulatory agencies) required in connection
with the authorization, execution and delivery of this Agreement by the Company
and Parent and the consummation by them of the transactions contemplated hereby.
The Company and Parent shall furnish all information required to be included in
the Proxy Statement and the Registration Statement, or for any application or
other filing to be made pursuant to the rules and regulations of any United
States, or foreign governmental body in connection with the transactions
contemplated by this Agreement. If either party receives a request for
additional information or documentary material from any governmental authority
with respect to the transactions contemplated hereby, then such party shall take
all reasonable efforts to make, or cause to be made, as soon as reasonably
practicable and after consultation with the other party, an appropriate response
in compliance with such request. The parties will cooperate in connection with
reaching any understandings, undertakings or agreements (oral or written)
involving the  
                                       26
   31
Federal Trade Commission, the Department of Justice or any other governmental
authority in connection with the transactions contemplated hereby.
 
     SECTION 5.05. STOCK OPTIONS.
 
          (a) At the Effective Time, the Company's obligations with respect to
     each outstanding option to purchase shares of Company Common Stock (each, a
     "Company Option") under the Company's 1990 Stock Option Plan and Director
     Stock Option Plan (the "Company Stock Option Plans"), whether vested or
     unvested, will be assumed by Parent. Each Company Option so assumed by
     Parent under this Agreement shall continue to have, and be subject to, the
     same terms and conditions set forth in the Company Stock Option Plans and
     agreement pursuant to which such Company Option was issued as in effect
     immediately prior to the Effective Time, except that (i) such Company
     Option will be exercisable for that number of Parent Common Shares equal to
     the product of the number of shares of Company Common Stock that were
     purchasable under such Company Option immediately prior to the Effective
     Time multiplied by the Exchange Ratio, rounded down to the nearest whole
     number of shares of Parent Common Shares (with any resulting fractional
     share paid in cash), and (ii) the per share exercise price for the shares
     of Parent Common Shares issuable upon exercise of such assumed Company
     Option will be equal to the quotient determined by dividing the exercise
     price per share of Company Common Stock at which such Company Option was
     exercisable immediately prior to the Effective Time by the Exchange Ratio,
     and rounding the resulting exercise price up to the nearest whole cent.
 
          (b) It is the intention of the parties that the Company Options
     assumed by Parent qualify following the Effective Time as incentive stock
     options as defined in the Code ("ISO's") to the extent the Company Options
     qualified as ISO's prior to the Effective Time.
 
          (c) After the Effective Time, Parent will issue to each holder of an
     outstanding Company Option a document evidencing the foregoing assumption
     by Parent.
 
          (d) Parent will file a registration statement on Form S-8 with the SEC
     covering the Company Options assumed by Parent under this Section 5.05 not
     later than the Effective Time.
 
     SECTION 5.06. COMPANY EMPLOYEE STOCK PURCHASE PLAN.
 
          (a) The Company shall take such actions as are necessary to establish
     a "new exercise date" (as such term is used in the Company's 1992 Employee
     Stock Purchase Plan (the "Company Stock Purchase Plan")) in accordance with
     the terms of the Company Stock Purchase Plan (the "New Exercise Date") for
     the then current offering period (as such term is used in the Company Stock
     Purchase Plan). The New Exercise Date shall be the last trading day on
     which the Parent Common Shares are traded on the Nasdaq National Market
     immediately prior to the Effective Time provided, that the New Exercise
     Date shall be conditioned upon the consummation of the Merger. On the New
     Exercise Date , the Company shall apply the funds credited as of such date
     under the Company Stock Purchase Plan within each participant's payroll
     withholdings account to the purchase of whole shares of Company Common
     Stock in accordance with the terms of the Company Stock Purchase Plan.
 
          (b) Employees of the Company as of the Effective Time shall be
     permitted to participate in Parent's Employee Stock Purchase Plan
     commencing on the first enrollment date following the Effective Time,
     subject to compliance with the eligibility provisions of such plan (with
     employees receiving credit, for purposes of such eligibility provisions,
     for service with the Company).
 
     SECTION 5.07. AGREEMENTS OF AFFILIATES.  The Company shall deliver to
Parent, prior to the date the Registration Statement becomes effective under the
Securities Act, a letter (the "Affiliate Letter") identifying all persons who
are, or may deemed to be, at the time of the Company Stockholders' Meetings,
"affiliates" of the Company for purposes of Rule 145 under the Securities Act.
The Company shall use its best efforts to cause each person who is identified as
an "affiliate" in the Affiliate Letter to deliver to Parent, prior to the
Effective Time, a written agreement (an "Affiliate Agreement") in substantially
the form of Exhibit A hereto. Parent shall use its best efforts to cause each
person who is an affiliate of Parent for purposes of Rule 145 under the
Securities Act to deliver to Parent, prior to the Effective Time, an Affiliate
Agreement.
 
                                       27
   32
 
     SECTION 5.08. INDEMNIFICATION AND INSURANCE.
 
          (a) The Certificate of Incorporation of the Surviving Corporation
     shall contain the provisions with respect to indemnification set forth in
     the By-Laws of the Company, which provisions shall not be amended, repealed
     or otherwise modified after the Effective Time in any manner that would
     adversely affect the rights thereunder existing at the Effective Time of
     individuals who at the Effective Time were directors, officers, employees
     or agents of the Company, unless such modification is required by law.
 
          (b) After the Effective Time, the Surviving Corporation and Parent
     shall, to the fullest extent permitted under applicable law or under the
     Surviving Corporation's and Parent's, as the case may be, Certificate of
     Incorporation or By-Laws, indemnify and hold harmless, each present and
     former director, officer, employee, fiduciary and agent of the Company or
     any of its subsidiaries (collectively, the "Indemnified Parties") against
     any costs or expenses (including attorneys' fees), judgments, fines,
     losses, claims, damages, liabilities and amounts paid in settlement in
     connection with any claim, action, suit, proceeding or investigation,
     whether civil, criminal, administrative or investigative, arising out of or
     pertaining to any action or omission occurring at or prior to the Effective
     Time (including, without limitation, the transactions contemplated by this
     Agreement). In the event of any such claim, action, suit, proceeding or
     investigation (whether arising before or after the Effective Time), (i) any
     counsel retained by the Indemnified Parties for any period after the
     Effective Time shall be reasonably satisfactory to the Surviving
     Corporation and Parent, (ii) after the Effective Time, the Surviving
     Corporation and Parent shall pay the reasonable fees and expenses of such
     counsel in a timely manner after statements therefor are received, and
     (iii) the Surviving Corporation and Parent will cooperate in the defense of
     any such matter; provided, however, that neither the Surviving Corporation
     nor Parent shall be liable for any settlement effected without its written
     consent (which consent shall not be unreasonably withheld). The Indemnified
     Parties as a group may retain only one law firm to represent them with
     respect to any single action unless there is, under applicable standards of
     professional conduct, a conflict on any significant issue between the
     positions of any two or more Indemnified Parties.
 
          (c) From and after the Effective Time, Parent and the Surviving
     Corporation shall honor all of the indemnity agreements entered into prior
     to the date hereof by Company with its respective officers and directors,
     whether or not such persons continue in their positions with Parent or the
     Surviving Corporation following the Effective Time.
 
          (d) From and after the Effective Time until at least six years after
     the Effective Time, Parent shall, or shall cause the Surviving Corporation
     to use its best efforts to maintain in effect directors' and officers'
     liability insurance covering those persons who are currently covered by the
     Company's directors' and officers' liability insurance policy (a copy of
     which has been heretofore delivered to Parent) of at least the same
     coverage and amounts, containing terms that are no less advantageous with
     respect to claims arising at or before the Effective Time than the
     Company's policies in effect immediately prior to the Effective Time
     provided, however, that in no event shall Parent or the Surviving
     Corporation, be required to expend in excess of 150% of the annual premium
     currently paid by Company for such coverage in which event the Parent shall
     purchase such coverage as is available for such 150% of such annual
     premium.
 
     SECTION 5.09. EMPLOYEE BENEFIT PLANS.  (a) Parent intends to include
Company employees in Parent's welfare plans (within the meaning of Section 3(1)
of ERISA) and fringe benefit plans on the same basis and terms as Parent
employees not later than two years following the Effective Time and, in any
event, with respect to particular welfare plans of Parent, upon the termination
of the equivalent Company welfare plans; and until such time of inclusion,
Parent intends to cause the Surviving Corporation to maintain in effect, on
terms not materially less favorable to employees of the Company as were in
effect at the Effective Time, all Employee Plans of the Company. In addition,
Parent intends that Company employees be eligible to participate in Parent's
stock option and stock purchase plans on the same basis and terms as Parent
employees from and after the Effective Time. Notwithstanding the foregoing,
Parent may at any time terminate or modify the terms of any such Employee Plans
if the cost of maintaining any such Employee Plan has increased by a material
amount or if, in the good faith judgment of Parent, continuing to maintain any
such Employee Plan conflicts in any material respect with Parent's overall
compensation policies then in effect.

          (b) Parent shall cause each of the persons listed on Section 1.05 of
     the Company Disclosure Schedule to be elected and remain in office as
     directors of the Surviving Corporation until such time as all of such
     person's Company Options outstanding at the Effective Time have vested in
     full in accordance with their respective terms.
 
     SECTION 5.10.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall give
prompt notice to Parent, and Parent shall give prompt notice to the Company, of
(i) any event known to the Company the occurrence, or non-occurrence, of which
would be likely to cause any representation or warranty contained in this
Agreement to be untrue or inaccurate in any material respect, and (ii) any
failure of the Company, Parent or Merger Sub, as the case may be, materially to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder provided, however, that the delivery of any notice
pursuant to this Section shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice; and provided, further,
that failure to give such notice shall not be treated as a breach of covenant
for the purposes of Sections 6.02(a) and 6.03(a) unless the failure to give such
notice is willful by the party required to give notice and results in material
prejudice to the other party.
 
     SECTION 5.11. FURTHER ACTION/TAX TREATMENT.  Upon the terms and subject to
the conditions hereof, each of the parties hereto in good faith shall use all
commercially reasonable efforts to take, or cause to be taken, all actions and
to do, or cause to be done, all other things necessary, proper or advisable to
consummate and make effective as promptly as practicable the transactions
contemplated by this Agreement, to obtain in a timely manner all necessary
waivers, consents and approvals and to effect all necessary registrations and
filings, and to otherwise satisfy or cause to be satisfied all conditions
precedent to its obligations under this Agreement. Each of Parent, Merger Sub
and the Company shall use its best efforts to cause the Merger to qualify, and

which could prevent the Merger from qualifying, as a reorganization under the
provisions of Section 368 of the Code.

with each other before issuing any press release or otherwise making any public
statements with respect to the Merger or this Agreement and shall not issue any
such press release or make any such public statement without the prior consent
of the other party, which shall not be unreasonably withheld; provided, however,
that a party may, without the prior consent of the other party, issue such press
release or make such public statement as may upon the advice of counsel be
required by law, the National Association of Securities Dealers or the NYSE if
it has used all reasonable efforts to consult with the other party.
 
     SECTION 5.13. LISTING OF PARENT COMMON SHARES.  Parent shall cause the
shares of Parent Common Shares to be issued in the Merger to be approved for
listing on the NYSE (or the principal exchange on which Parent's Common Shares
are then trading) on or before the Effective Time.
 
     SECTION 5.14. CONVEYANCE TAXES.  Parent and the Company shall cooperate in
the preparation, execution and filing of all returns, questionnaires,
applications or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees, and any similar taxes which become
payable in connection with the transactions contemplated hereby that are
required or permitted to be filed on or before the Effective Time.
 
     SECTION 5.15. ACCOUNTANTS' LETTERS.  Each party, upon reasonable notice
from the other party, shall use its best efforts to cause its independent public
accountants (Price Waterhouse LLP in the case of the Company, and Coopers &
Lybrand LLP in the case of Parent) to deliver to the other party a letter
covering such matters as are customarily addressed in accountant's "comfort"
letters in transactions similar to those contemplated by this Agreement.
 
     SECTION 5.16. EMPLOYMENT AGREEMENTS.  Prior to the Effective Time, Parent
shall offer to each of the persons listed on Exhibit B hereto a form of

subject to the satisfaction at or prior to the Effective Time of the following
conditions:

     Statement shall have been declared effective by the SEC under the
     Securities Act. No stop order suspending the effectiveness of the
     Registration Statement shall have been issued by the SEC and no proceedings
     for that purpose and no similar proceeding in respect of the Proxy
     Statement shall have been initiated or, to the knowledge of Parent or the
     Company, threatened by the SEC;
 
          (b) Stockholder Approval.  This Agreement and the Merger shall have

     shall be in effect, nor shall any proceeding brought by any administrative
     agency or commission or other governmental authority or instrumentality,
     domestic or foreign, seeking any of the foregoing be pending; and there
     shall not be any action taken, or any statute, rule, regulation or order
     enacted, entered, enforced or deemed applicable to the Merger, which makes
     the consummation of the Merger illegal;
 
          (e) Tax Opinions.  Parent and the Company shall have received
     substantially identical written opinions of Testa, Hurwitz & Thibeault and
     Wilson, Sonsini, Goodrich & Rosati respectively, in form and substance
     reasonably satisfactory to them to the effect that the Mergers will
     constitute a reorganization within the meaning of Section 368 of the Code;
     and
 
          (f) Accountants' Pooling Letters.  The Company and Parent shall have
     received a letter from each of Price Waterhouse LLP and Coopers & Lybrand
     LLP confirming their respective opinions dated at the Effective Time, to
     the effect that the Merger qualifies for a pooling of interests accounting
     treatment if consummated in accordance with this Agreement.

SUB.  The obligations of Parent and Merger Sub to effect the Merger are also

     correct would not have a Material Adverse Effect on the Company; and Parent
     and Merger Sub shall have received a certificate to such effect signed by
     the President and Chief Financial Officer of the Company;
 
          (b) Agreements and Covenants.  The Company shall have performed or

     threatened any action or proceeding (or any investigation or other inquiry
     that could reasonably be expected to result in such an action or
     proceeding) by any governmental authority or administrative agency before
     any governmental authority, administrative agency or court of competent
     jurisdiction, nor shall there be in effect any judgment, decree or order of
     any governmental authority, administrative agency or court of competent
     jurisdiction, in either case, seeking to prohibit or limit Parent from
     exercising all rights and privileges pertaining to its ownership of the
     Surviving Corporation or the ownership or operation by Parent or any of its
     subsidiaries of all or a portion of the business or assets of Parent or any
     of its subsidiaries, or seeking to compel Parent or any of its subsidiaries
     to dispose of or hold separate all or any material portion of the business
     or assets of Parent or any of its subsidiaries, as a result of the Merger
     or the transactions contemplated by this Agreement if any of the foregoing
     shall have a Material Adverse Effect on Parent;
 
          (e) Affiliate Agreements.  Parent shall have received from each person
     who is identified in the Affiliate Letter as an "affiliate" of the Company
     an Affiliate Agreement, and each such Affiliate Agreement shall be in full

     with the Parent Disclosure Schedule) shall be true and correct in all
     material respects on and as of the Effective Time, with the same force and
     effect as if made on and as of the Effective Time, except for (i) changes
     contemplated by this Agreement, (ii) those representations and warranties
     which address matters only as of a particular date (which shall remain true
     and correct as of such date) and (iii) failures to be true and correct that
     would not have a Material Adverse Effect on Parent and Merger Sub, and the
     Company shall have received a certificate to such effect signed by the
     President and Chief Financial Officer of Parent;
 
          (b) Agreements and Covenants.  Parent and Merger Sub shall have

          (a) by mutual written consent duly authorized by the Boards of
     Directors of Parent and the Company; or

     Merger to occur on or before such date); or
 
          (c) by either Parent or the Company if a court of competent
     jurisdiction or governmental, regulatory or administrative agency or

          (f) by Parent or the Company, upon a breach of any representation,
     warranty, covenant or agreement on the part of the Company or Parent and
     Merger Sub, respectively, set forth in this Agreement or if any
     representation or warranty of the Company or Parent and Merger Sub,

     whole, immediately prior to such transaction (or proposal).
 
          (d) The fee payable pursuant to Section 7.03(b) shall be paid within

     expenses of the Company's counsel, accountants and financial advisors) in
     connection with matters relating to the Company's filings under the HSR Act

TERADYNE, INC.
321 Harrison Avenue
Boston, MA 02118
 
Ladies and Gentlemen:
 
     Pursuant to the terms of the Agreement and Plan of Merger dated as of
September 5, 1995 (the "Agreement"), among TERADYNE, INC., a Massachusetts
corporation ("Parent"), M Acquisition Corporation, a Delaware corporation and
wholly-owned subsidiary of Parent ("Merger Sub"), and MEGATEST CORPORATION, a
Delaware corporation (the "Company"), Parent will acquire the Company through
the merger of Merger Sub with and into the Company (the "Merger"). Subject to
the terms and conditions of the Agreement, at the Effective Time (as defined in
the Agreement), outstanding shares of the common stock, $.001 value per share,
of the Company (the "Company Common Stock") will be converted into the right to
receive shares of the common stock, $.125 par value per share, of Parent (the
"Parent Common Stock"), on the basis described in the Agreement.
 
     The undersigned has been advised that as of the date hereof it may be
deemed to be an "affiliate" of 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, and Staff Accounting Bulletins 65 and 76 of the Commission.
 
     The undersigned understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, stockholders of
Parent, the Company, other shareholders of the Company and their respective
counsel and accountants.
 
     The undersigned represents and warrants to and agrees with Parent that:
 
      1. The undersigned has full power to execute and deliver this Affiliate
Agreement and to make the representations and warranties herein and to perform
its obligations hereunder;
 
      2. The undersigned has carefully read this letter and the Agreement and
discussed its requirements and other applicable limitations upon its ability to
sell, transfer or otherwise dispose of Parent Common Stock to the extent the
undersigned felt necessary, with its counsel or counsel for the Company.
 
      3. The undersigned shall not make any sale, transfer or other disposition
of Parent Common Stock in violation of the Act or the Rules and Regulations.
 
      4. The undersigned has been advised that the issuance of shares of Parent
Common Stock to the undersigned in connection with the Merger has been or will
be registered with the Commission under the Act on a Registration Statement on
Form S-4. However, the undersigned has also been advised that, since at the time
the Merger was submitted for a vote of the shareholders of the Company the
undersigned may be deemed to have been an affiliate of the Company and the
distribution by the undersigned of any Parent Common Stock has not been
registered, and is not exempt, under the Act, the undersigned may not sell,
transfer or otherwise dispose of Parent Common Stock issued to the undersigned
in the Merger unless (i) such sale, transfer or other disposition has been
registered under the Act, (ii) such sale, transfer or other disposition is made
in conformity with the requirements of Rule 145 promulgated by the Commission
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.
 
      5. Parent is under no obligation to register the sale, transfer or other
disposition of Parent Common Stock by the undersigned or on its behalf under the
Act or to take any other action necessary in order to make
   42
\ 
compliance with an exemption from such registration available, provided,
however, that Parent shall use best efforts to file on a timely basis with the
SEC all reports required to be filed by it pursuant to Section 13 or 15(d) of
the Exchange Act.
 
      6. Stop transfer instructions will be given to Parent's transfer agent
with respect to the Parent Common Stock and Parent may cause there to be placed
on the certificates for the Parent Common Stock issued to the undersigned, or
any substitutions therefor, a legend stating in substance:
 
              "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED
         IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE
         SECURITIES ACT OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS
         CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE
         TERMS OF AN AGREEMENT DATED [                 ] 1995 BETWEEN
         THE REGISTERED HOLDER HEREOF AND [PARENT], A COPY OF WHICH
         AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF PARENT".
 
      7. Unless the transfer by the undersigned of its Parent Common Stock has
been registered under the Act or is a sale made in conformity with the
provisions of Rule 145, Parent reserves the right to put the following legend on
the certificates issued any transferee of the undersigned:
 
          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A
     PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145
     PROMULGATED UNDER THE SECURITIES ACT OF 1933 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 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE
     TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE
     REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933."
 
      8. The legends set forth in paragraphs 6 and 7 above shall be removed by
delivery of substitute certificates without such legend if the undersigned shall
have delivered to Parent a copy of a letter from the staff of the Commission, or
an opinion of counsel in form and substance reasonably satisfactory to Parent,
to the effect that such legend is not required for purposes of the Act.
 
      9. The undersigned is the beneficial owner of (i.e. has sole or shared
voting or investment power with respect to) all the shares of Company Common
Stock and options to purchase Company Common Stock indicated on the last page
hereof (the "Company Securities"). Except for the Company Securities, the
undersigned does not beneficially own any shares of Company Common Stock or any
other equity securities of the Company or any options, warrants or other rights
to acquire any equity securities of the Company.
 
     10. Notwithstanding any other provision hereof to the contrary, the
undersigned has not at any time since August 21, 1995 or in contemplation of the
Merger engaged, and will not, after the Effective Time (as defined in the
Agreement) and until 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 or annual 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, engage, in any sale, exchange, transfer, pledge, disposition of
or grant of any option, the establishment of any "short" or put-equivalent
position with respect to or the entry into any similar transaction intended to
reduce the risk of the undersigned's risk of ownership of or investment in, any
of the following:
 
          (a) any shares of Parent Common Stock which the undersigned may
     acquire in connection with the Merger, or any securities which may be paid
     as a dividend or otherwise distributed thereon or with respect thereto or
     issued or delivered in exchange or substitution therefor (all such shares
     and other securities
   43
 
     being referred to herein, collectively, as "Restricted Securities"), or any
     option, right or other interest with respect to any Restricted Securities;
 
          (b) any Company Securities; or
 
          (c) any shares of Company Common Stock or other Company equity
     securities which the undersigned purchases or otherwise acquires after the
     execution of this Affiliate Agreement.
 
     11. As promptly as practicable following the Merger, Parent shall publish
results covering at least 30 days of combined operations of the Company and
Parent in the form of a quarterly or annual 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; provided, however, that Parent
shall be under no obligation to publish any such financial information other
than with respect to a fiscal quarter of Parent.
 
     12. The undersigned has no present plan or intention to engage in a sale,
exchange, transfer, distribution, (including a distribution by a partnership to
its partners or by a corporation to its stockholders), redemption or reduction
in any way of the undersigned's risk of ownership by short sale or otherwise, or
other disposition, directly or indirectly (such actions being collectively
referred to herein as a "Sale") of any of the shares of Parent Common Stock to
be received by the undersigned in the Merger. The undersigned is not aware of,
or participating in, any plan on the part of the stockholders of the Company to
engage in a Sale or Sales of the Parent Common Stock to be received in the
Merger such that the aggregate fair market value, as of the Effective Date of
the Merger, of the shares subject to such Sales would exceed 50% of the
aggregate fair market value of all shares of outstanding Company Common Stock
immediately prior to the Merger. Except to the extent written notification to
the contrary is received by Parent from the undersigned prior to the Merger, the
representations and warranties contained herein shall be true and correct at all
times from the date hereof through the date on which the Merger occurs.
 
     13. The undersigned intends to vote all Company Common Stock held by him in
favor of the Merger.
 
                 [REMAINDER OF PAGE LEFT INTENTIONALLY BLANK.]
   44
 
     14. The undersigned will not exercise dissenters' rights in connection with
the Merger.
