ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS
         ------------------------------------

     On September 16, 1995, the Board of Directors (the "Board") of Data
Measurement Corporation (the "Corporation") unanimously approved an Agreement
and Plan of Reorganization (the "Merger Agreement") by and among Measurex
Corporation (the "Buyer"), MX Acquisition Corp. (the "Acquisition Subsidiary")
and the Corporation. The Merger Agreement would result in the merger of the
Corporation with the Acquisition Subsidiary (the "Merger"), a wholly owned
subsidiary of the Buyer.

     Upon the Closing of the Merger Agreement (the "Closing"), holders (the
"Stockholders") of issued and outstanding shares of the Corporation's common
stock (the "Stock") would receive $18.625 in cash for each share of the Stock
owned by each Stockholder and holders ("Rightsholders") of options, warrants or
Convertible Subordinated Debentures due 1997 (the "Rights") will receive cash
equal to the spread between the exercise or conversion price under the
applicable Rights and $18.625.  The Corporation's obligation to the Federal
Deposit Insurance Corporation ("FDIC") under the terms of the FDIC's Convertible
Subordinated Debenture will remain outstanding.

     As a result of the Merger, the Corporation and all of its assets, rights
and obligations will be owned by the combined entity, which will then be known
as Measurex Data Measurement Corporation ("MDMC").  MDMC will be a wholly owned
subsidiary of the Buyer.

     The Closing is contingent upon certain conditions set forth in the Merger
Agreement, the approval of the Merger Agreement by the Stockholders holding a
majority of the issued and outstanding shares of the Corporation's Stock, and
upon expiration or early termination of the waiting period under the Hart-Scott-
Rodino Anti-Trust Improvements Act of 1976.

     In connection with the Merger Agreement, the Buyer also negotiated and
entered into Voting and Stock Option Agreements with certain individual
Stockholders of the Corporation (the "Stockholder Agreements").  The
Stockholders entering into the Stockholder Agreements were Dominique Gignoux,
Frederick Rolandi, John Sanders, Jim Collins and Ira Hunt (the "Selling
Stockholders").  Mr. Gignoux is the President and CEO of the Corporation and a
member of the Board.  Mr. Rolandi is Vice President - Finance and CFO of the
Corporation and a member of the Board.  Messers. Sanders, Collins and Hunt are
also members of the Board.

     The Stockholder Agreements require each of the Selling Stockholders to vote
in favor of the Merger Agreement at any meeting of the Stockholders called for
the purpose of approving the Merger Agreement and provide to Buyer a proxy
covering all shares held by the Selling Stockholder.  The Stockholder Agreements
also give the Buyer an option to purchase the Selling Stockholders' shares at
$18.625 per share and the right to cause the Selling Stockholder to exercise any
Rights held by the Selling Stockholder and sell the shares of Stock obtained by
such exercise to Buyer at $18.625 per share.
<PAGE>
 
     As of September 16, 1995, the Selling Stockholders owned 272,550 shares of
the Stock, which represented 19.8% of the Corporation's issued and outstanding
shares.  The Selling Stockholders also owned Rights at varying exercise or
conversion prices, for the purchase of 84,750 additional shares of the
Corporation's Stock which, when combined with the currently issued and
outstanding shares, would represent 24.4% of the Corporation's Stock on a
partially diluted basis (assuming exercise only of the Selling Stockholders'
options) and 19.1% of the Corporation's Stock on a fully diluted basis (assuming
exercise or conversion of all exercisable Rights).

     The Merger Agreement will be presented to the Stockholders for their
approval as soon as reasonably possible, pursuant to the issuance of a Notice of
Special Meeting of the Stockholders and Proxy Statement (the "Proxy Statement").

                     AGREEMENT AND PLAN OF REORGANIZATION


          THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is
entered into as of September 16, 1995, by and among MEASUREX CORPORATION, a
Delaware corporation ("Measurex"), MX ACQUISITION CORP., a Delaware corporation
and a wholly owned subsidiary of Measurex ("Merger Sub"), and DATA MESUREMENT
CORPORATION, a Delaware corporation ("DMC").

                                 RECITALS

          The Boards of Directors of Measurex and DMC each believe it is in the
best interests of their respective corporations that Merger Sub merge with and
into DMC (the "Merger") upon the terms and subject to the conditions set forth
herein.

          DMC, Measurex and Merger Sub desire to make certain representations
and warranties and other agreements in connection with the Merger.

          Concurrent with the execution of this Agreement and as an inducement
to Measurex to enter into this Agreement, certain stockholders of DMC have
entered into a voting and stock option agreement dated as of the date hereof in
the form attached to this Agreement as Exhibit A (the "Voting and Option
Agreement") with respect to those shares of DMC Common Stock owned by such
stockholders.

          NOW, THEREFORE, in consideration of the covenants and representations
set forth herein, and for other good and valuable consideration, the parties
agree as follows:


                                   ARTICLE I
                                  THE MERGER
                                  ----------

          1.1  The Merger.  At the Effective Time (as defined in Section 1.2)
and subject to and upon the terms and conditions of this Agreement and the
applicable provisions of the Delaware General Corporation Law ("DGCL"), Merger
Sub shall be merged with and into DMC, the separate corporate existence of
Merger Sub shall cease and DMC shall continue as the surviving corporation.  DMC
as the surviving corporation in the Merger is hereinafter sometimes referred to
as the "Surviving Corporation."

          1.2  Closing; Effective Time.  The closing of the transactions
contemplated hereby (the "Closing") shall take place as soon as practicable
after the satisfaction or waiver of each of the conditions set forth in Article
VI hereof or at 

                                       1
<PAGE>
 
such other time as the parties hereto agree (the date on which the Closing shall
occur, the "Closing Date" or the "Effective Date"). The Closing shall take place
at the offices of Brobeck, Phleger & Harrison, Spear Street Tower, One Market,
San Francisco, CA, or at such other location as may be mutually agreed to by the
parties. In connection with the Closing, the parties hereto shall cause the
Merger to be consummated by filing a certificate of merger in form reasonably
satisfactory to the parties hereto (the "Certificate of Merger") with the
Secretary of State of the State of Delaware in accordance with the relevant
provisions of the DGCL (the time of such filing, the "Effective Time".)

          1.3  Effect of the Merger.  At the Effective Time, the effect of the
Merger shall be as provided in this Agreement and the applicable provisions of
the DGCL.  Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time, all the property, rights, privileges, powers and
franchises of DMC and Merger Sub shall vest in the Surviving Corporation, and
all debts, liabilities and duties of DMC and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.

          1.4  Certificate of Incorporation; Bylaws.

          (a) 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; provided, however, that Article I of the Certificate of Incorporation
of the Surviving Corporation shall be amended to read as follows:  "The name of
the corporation is Measurex Data Measurement Corporation."

          (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.

          1.5  Directors and Officers.  The directors and officers of Merger Sub
at the Effective Time shall, from and after the Effective Time, be the directors
and officers, respectively, of the Surviving Corporation until their successors
have been duly elected or appointed and qualified or until their earlier death,
resignation or removal in accordance with the Surviving Corporation's
Certificate of Incorporation and Bylaws.

          1.6  Conversion and Cancellation of Shares.  By virtue of the Merger
and without any action on the part of Measurex, Merger Sub or DMC or the holders
of any of the following securities, the manner of converting and cancelling
shares in connection with the Merger shall be as follows:

                                       2
<PAGE>
 
          (a) Conversion of Shares.  Each share of common stock, par value $.01
per share, of DMC ("DMC Common Stock") issued and outstanding immediately prior
to the Effective Time (other than shares of DMC Common Stock owned by Measurex,
Merger Sub or any other direct or indirect subsidiary of Measurex (collectively,
the "Measurex Companies") or shares of DMC Common Stock that are held by
stockholders duly exercising appraisal rights pursuant to Section 262 of the
DGCL ("Dissenting Shares")), shall be converted into, and become exchangeable
for $18.625 in cash (the "Cash Merger Consideration").  At the Effective Time,
all such shares of DMC Common Stock shall no longer be outstanding and shall be
canceled and retired and shall cease to exist, and each certificate (each a
"Certificate") representing any of such shares shall thereafter represent only
the right to receive the Cash Merger Consideration into which such shares have
been converted pursuant to this Article I, or the right, if any, to receive
payment from the Surviving Corporation of the "fair value" of such shares as
determined in accordance with Section 262 of the DGCL.

          (b) Cancellation of Shares.  Each share of DMC Common Stock issued and
outstanding immediately prior to the Effective Time and owned by any of the
Measurex Companies, and each such share issued and held in DMC's treasury
immediately prior to Effective Time, shall, at the Effective Time and by virtue
of the Merger, and without any action on the part of the holder thereof, cease
to be outstanding, shall be cancelled and retired without payment of any
consideration therefor and shall cease to exist.

          (c) Merger Sub Capital Stock.  At the Effective Time, each share of
Common Stock, par value $.01 per share, of Merger Sub ("Merger Sub Common
Stock") issued and outstanding immediately prior to the Effective Time shall
continue to be issued and shall be converted into one validly issued, fully paid
and non-assessable share of common stock 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.

          (d) Adjustments.  If between the date of this Agreement and the
Effective Time the number of shares of DMC Common Stock shall have been changed
into a different number of shares or a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split-up,
combination, exchange of shares or the like, the amount of the Cash Merger
Consideration shall be correspondingly adjusted.

                                       3
<PAGE>
 
          1.7  Payment for DMC Stock, Stock Options and Debentures.

          (a) At the Effective Time, Measurex shall make available or cause to
be made available to the party specified by Measurex as the exchange agent (the
``Exchange Agent'') amounts sufficient in the aggregate to provide all funds
necessary for the Exchange Agent to make payments pursuant to Section 1.6(a)
hereof to holders of DMC Common Stock who are to receive the Cash Merger
Consideration and amounts as necessary to make the payments specified in Section
1.10 (all such amounts collectively referred to as the "Merger Consideration.")
Measurex, at its sole option, may act as Exchange Agent.  Promptly after the
Effective Time, the Surviving Corporation shall cause to be mailed to each
person who was, at the Effective Time, a holder of record (other than holders
holding Shares that were cancelled under the terms of Section 1.6(b)) of DMC
Common Stock, stock options or debentures, a form (mutually agreed to by
Measurex and DMC) of letter of transmittal and instructions for use in effecting
the surrender of the Certificates or documents which, immediately prior to the
Effective Time, represented any of such DMC Common Stock, stock options or
debentures in exchange for payment of the Cash Merger Consideration in the case
of holders of DMC Common Stock and the amounts provided for in Section 1.10 in
the case of holders of DMC stock options or debentures.  Upon surrender to the
Exchange Agent of such documents or Certificates, together with such letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, and only upon such surrender, Measurex shall promptly cause to be paid
to the persons entitled thereto a check in the amount to which such persons are
entitled, after giving effect to any required tax withholdings.

          (b) No interest will be paid or will accrue on the amount payable
hereunder.  If payment is to be made to a person other than the registered
holder of the Certificate or document surrendered, it shall be a condition of
such payment that the Certificate or document so surrendered shall be properly
endorsed and otherwise in proper form for transfer, as determined by the
Exchange Agent or Measurex, and that the person requesting such payment shall
pay any transfer or other taxes required by reason of the payment to a person
other than the registered holder of the Certificate or document surrendered or
establish to the satisfaction of Measurex or the Exchange Agent that such tax
has been paid or is not payable.  Three hundred and sixty days following the
Effective Time, Measurex shall be entitled to cause the Exchange Agent to
deliver to it any funds (including any interest received with respect thereto)
made available to the Exchange Agent which have not been disbursed to holders of
Certificates or documents formerly representing DMC Common Stock, stock options
or debentures outstanding on the Effective Time, and thereafter such holders
shall be entitled to look to Measurex only as general creditors thereof with
respect to the amounts payable upon due surrender of their Certificates or
documents.  Notwithstanding the foregoing, 

                                       4
<PAGE>
 
neither the Exchange Agent nor any party hereto shall be liable to any holder of
Certificates or documents formerly representing DMC Common Stock, stock options
or debentures for any amount paid to a public official as required by any
applicable abandoned property, escheat or similar law.

          (c) Except as otherwise provided in subsection (b) above, Measurex
shall pay all charges and expenses, including those of the Exchange Agent, in
connection with the foregoing.

          1.8  Transfers.  After the Effective Time, there shall be no transfers
on the stock transfer books of DMC of the shares of DMC Common Stock, stock
options or debentures that were outstanding immediately prior to the Effective
Time.  If, after the Effective Time, Certificates or documents are presented to
the Surviving Corporation, they shall be cancelled and exchanged for the
consideration to be paid upon the due surrender of and in respect of such
Certificates and documents pursuant to this Agreement in accordance with the

authority, and has all necessary licenses and permits, to own its properties and
to carry on its business as now being conducted and as proposed to be conducted
and is duly qualified to do business and is in good standing in each
jurisdiction in which the failure to be so qualified and in good standing would

correct copy of the Certificate of Incorporation and Bylaws or other charter
documents, as applicable, of DMC and each of the DMC Subsidiaries, each as

similar interest in, or any interest convertible or exchangeable or exercisable
for, any equity or similar interest in, any corporation, partnership, joint
venture or other business association or entity.  DMC is the owner of all
outstanding shares of capital stock of each of its subsidiaries (the "DMC
Subsidiaries" and each a "DMC Subsidiary") and all such shares are duly
authorized, validly issued, fully paid and nonassessable.  All of the

1995 of $240,000. All outstanding shares of DMC Common Stock are duly
authorized, validly issued, fully paid and non-assessable and are free of any
liens or encumbrances other than any liens or encumbrances created by or imposed
upon the holders thereof, and are not subject to preemptive rights or rights of

corporate action on the part of DMC, subject only to the approval of the Merger
by holders of a majority of the outstanding shares of DMC Common Stock.  This
Agreement has been duly executed and delivered by DMC and constitutes the valid
and binding obligation of DMC, enforceable against it in accordance with its
terms.  No consent, approval, order or authorization of, or registration,
declaration or filing with, any court, administrative agency or commission or
other governmental authority or instrumentality ("Governmental Entity") is
required by or with respect to DMC or any of the DMC Subsidiaries in connection
with the execution and delivery of this Agreement or the consummation of the
transactions contemplated hereby, except for (i) the filing of the Certificate
of Merger as provided in Section 1.2, (ii) the filing with the Securities and
Exchange Commission (the "SEC") and the National Association of Securities
Dealers, Inc. (the "NASD") of the Proxy Statement relating to the DMC

approvals, orders, authorizations, registrations, declarations and filings as
may be required under applicable state securities laws and the securities laws
of any foreign country; (iv) such filings as may be required under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended ("HSR"); and (v)
such other consents, authorizations, filings, approvals and registrations which,
if not obtained or made, would not have a Material Adverse Effect on DMC, and
would not prevent, alter or materially delay any of the transactions
contemplated by this Agreement.

          2.5  Noncontravention.  The execution and delivery of this Agreement
by DMC does not, and the consummation of the transactions contemplated hereby
will not, conflict with, or result in any violation of, or default under (with
or without notice or lapse of time, or both), or create in any party the right
to modification, termination, cancellation or acceleration of any obligation or
loss of any material benefit under (i) any provision of the Certificate of
Incorporation or Bylaws or other similar organizational document of DMC or any
of the DMC Subsidiaries or (ii) any Material Contract (as defined in Section
2.28) to which DMC and any of the DMC Subsidiaries is a party, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to DMC or any of the DMC Subsidiaries
or any of their properties or assets.

          2.6  SEC Documents; Financial Statements.  DMC has furnished to

by 

                                       9
<PAGE>
 
DMC since December 31, 1990, and, prior to the Effective Time, DMC will have
furnished Measurex with true and complete copies of any additional documents
filed with the SEC by DMC prior to the Effective Time (collectively, the "DMC
SEC Documents"). In addition, DMC has made available to Measurex all exhibits to
the DMC SEC Documents filed prior to the date hereof, and will promptly make
available to Measurex all exhibits to any additional DMC SEC Documents filed
prior to the Effective Time. All documents required to be filed as exhibits to
the DMC SEC Documents have been so filed, and all material contracts so filed as
exhibits are in full force and effect, except those which have expired or
terminated in accordance with their terms, and neither DMC nor any of the DMC
Subsidiaries is in default thereunder. As of their respective filing dates, the
DMC SEC Documents complied in all material respects with the requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Securities Act, and none of the DMC SEC Documents contained any untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements made therein, in light of the
circumstances in which they were made, not misleading, except to the extent
corrected by a subsequently filed DMC SEC Document. The financial statements of
DMC, including the notes thereto, included in the DMC SEC Documents (the "DMC
Financial Statements") were complete and correct in all material respects as of
their respective dates, complied as to form in all material respects with
applicable accounting requirements and with the published rules and regulations
of the SEC with respect thereto as of their respective dates, and have been
prepared in accordance with generally accepted accounting principles applied on
a basis consistent throughout the periods indicated (except as may be indicated
in the notes thereto or, in the case of unaudited statements included in
Quarterly Reports on Form 10-Q, as permitted by Form 10-Q of the SEC). The DMC
Financial Statements fairly present the consolidated financial condition and
operating results of DMC and the DMC Subsidiaries as of the dates and during the
periods indicated therein (subject, in the case of unaudited statements, to
normal, recurring year-end adjustments). There has been no change in DMC
accounting policies except as described in the notes to the DMC Financial
Statements.

          2.7  Absence of Certain Changes.  Since June 30, 1995, (the "DMC
Balance Sheet Date"), DMC has conducted its business in the ordinary course
consistent with past practice and there has not occurred:  (i) any change, event
or condition (whether or not covered by insurance) that has resulted in, or
might reasonably be expected to result in, a Material Adverse Effect on DMC;
(ii) any acquisition, sale or transfer of any material asset of DMC or any of
the DMC Subsidiaries other than in the ordinary course of business and
consistent with past practice; (iii) any change in accounting methods or
practices (including any change in depreciation or amortization policies or
rates) by DMC or any revaluation by DMC of any of its or any of the DMC
Subsidiaries' assets; (iv) any declaration, setting aside, or payment of a
dividend or other distribution with respect to the 

                                      10
<PAGE>
 
shares of DMC, or any direct or indirect redemption, purchase or other
acquisition by DMC of any of its shares of capital stock; (v) any Material
Contract entered into by DMC or any of the DMC Subsidiaries, other than in the
ordinary course of business and as provided to Measurex, or any material adverse
amendment or termination of, or default under, any Material Contract to which
DMC or any of the DMC Subsidiaries is a party or by which it is bound; (vi) any
increase in the compensation payable or to become payable by DMC to any of its
officers, directors, consultants or employees (except for salary or rate
increases granted to such persons in the ordinary course of business and
consistent with prior practice); (vii) any (A) grant of any severance or
termination pay to any director, officer or employee of DMC or any of the DMC
Subsidiaries, (B) entering into of any employment, deferred compensation or
other similar agreement (or any amendment to any such existing agreement) with
any director, officer or employee of DMC or any DMC Subsidiary, (C) any increase
in benefits payable under any existing severance or termination pay policies or
employment agreements, or (D) any increase in compensation, bonus or other
benefits payable to directors, officers or employees of DMC or any DMC
Subsidiary; or (viii) any negotiation or agreement by DMC or any of the DMC
Subsidiaries to do any of the things described in the preceding clauses (i)
through (vii) (other than negotiations with Measurex and its representatives
regarding the transactions contemplated by this Agreement).

          2.8  Absence of Undisclosed Liabilities.  DMC has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
Balance Sheet included in DMC's Quarterly Report on Form 10-Q for the quarter
ended June 30, 1995 (the "DMC Balance Sheet"), (ii) those incurred in the
ordinary course of business and not required to be set forth in the DMC Balance
Sheet under generally accepted accounting principles, (iii) those incurred in
the ordinary course of business since the DMC Balance Sheet Date and consistent
with past practice; (iv) those incurred in connection with the execution of this
Agreement and the transactions contemplated hereby; and (v) those that could not
reasonably be expected to have a Material Adverse Effect.

          2.9  Litigation.  There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of DMC, threatened
against DMC or any of the DMC Subsidiaries or any of their respective properties
or any of their respective officers or directors (in their capacities as such)
that, individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect on DMC.  There is no judgment, decree or order against
DMC or any of the DMC Subsidiaries, or, to the knowledge of DMC, any of their
respective directors or officers (in their capacities as such), that could
prevent, enjoin, alter or materially delay any of the transactions contemplated
by this Agreement, or that could reasonably be expected to have a Material
Adverse Effect.

<PAGE>
 
          2.10  Restrictions on Business Activities.  There is no agreement,
judgment, injunction, order or decree binding upon DMC or any of the DMC
Subsidiaries that could reasonably be expected to have a Material Adverse Effect
by prohibiting or impairing any current or future business practice of DMC or
any of the DMC Subsidiaries, any acquisition of property by DMC or any of the
DMC Subsidiaries or the conduct of business by DMC or any of the DMC
Subsidiaries as currently conducted or as proposed to be conducted by DMC or any
of the DMC Subsidiaries.

          2.11  Governmental Authorization.  DMC and each of the DMC
Subsidiaries have obtained each federal, state, county, local or foreign
governmental consent, license, permit, grant, or other authorization of a
Governmental Entity (i) pursuant to which DMC or any of the DMC Subsidiaries
currently operates or holds any interest in any of its properties or (ii) that
is required for the operation of DMC's or any of the DMC Subsidiaries' business
or the holding of any such interest (herein collectively referred to as "DMC
Authorizations"), and all of such DMC Authorizations are in full force and
effect, except where the failure to obtain or have any of such DMC
Authorizations could not reasonably be expected to have a Material Adverse
Effect.

          2.12  Title to Property.  DMC and the DMC Subsidiaries have good and
marketable title to all of their respective properties, interests in properties
and assets, real and personal, reflected in the DMC Balance Sheet or acquired
after the DMC Balance Sheet Date (except for intellectual property rights which
are governed by Section 2.13 below and except for properties, interests in
properties and assets sold or otherwise disposed of since the DMC Balance Sheet
Date in the ordinary course of business), free and clear of all mortgages,
liens, pledges, charges or encumbrances of any kind or character, except (i) the
lien of current taxes not yet due and payable and (ii) liens securing debt which
is reflected on the DMC Balance Sheet.  The plants, property and equipment of
DMC and the DMC Subsidiaries that are used in the operations of their businesses
are in good operating condition and repair, ordinary wear and tear excepted.
All properties used in the operations of DMC and the DMC Subsidiaries are
reflected in the DMC Balance Sheet to the extent generally accepted accounting
principles require the same to be reflected.  The DMC Disclosure Schedule
identifies each parcel of real property owned or leased by DMC or any of the DMC
Subsidiaries.

          2.13  Intellectual Property.

          (a) DMC and the DMC Subsidiaries own, or are licensed or otherwise
possess legally enforceable rights to use all patents, trademarks, trade names,
service marks, copyrights, and any applications therefor, maskworks, net lists,

                                      12
<PAGE>

object code form), and tangible or intangible proprietary information or
material ("Intellectual Property") that are used or proposed to be used in the
business of DMC and the DMC Subsidiaries as currently conducted or as proposed
to be conducted by DMC and the DMC Subsidiaries.

          (b) The DMC Disclosure Schedule lists (i) all patents and patent
applications and all registered and unregistered trademarks, trade names and
service marks, registered and unregistered copyrights, and maskworks, which DMC

Intellectual Property right has been issued or registered or in which any
application for such issuance and registration has been filed, (ii) all
licenses, sublicenses and other agreements as to which DMC is a party and

trademarks or copyrights, including software ("Third Party Intellectual Property
Rights") which are incorporated in, are, or form a part of any product produced
by DMC or any DMC Subsidiary, the absence of which could reasonably be expected
to have a Material Adverse Effect.

          (c) There is no unauthorized use, disclosure, infringement or
misappropriation of any Intellectual Property rights of DMC or any of the DMC
Subsidiaries, any trade secret, or any Intellectual Property right of any third
party to the extent licensed by or through DMC or any of the DMC Subsidiaries,
by any third party, including any employee or former employee of DMC or any of
the DMC Subsidiaries, which could reasonably be expected to have a Material
Adverse Effect.  Neither DMC nor any of the DMC Subsidiaries has entered into

of any Intellectual Property, other than indemnification provisions contained in
purchase orders arising in the ordinary course of business.

          (d) DMC is not, nor will it be as a result of the execution and
delivery of this Agreement or the performance of its obligations under this
Agreement, in breach of any license, sublicense or other agreement relating to
the Intellectual Property or Third Party Intellectual Property Rights, the
breach of which would have a Material Adverse Effect.

          (e) All patents, registered trademarks, service marks and copyrights
held by DMC and the DMC Subsidiaries are valid and subsisting.  DMC (i) has not
been sued in any suit, action or proceeding which involves a claim of

of any trade secret or other proprietary right of any third party; (ii) has no
knowledge that the manufacturing, marketing, licensing or sale of its products

<PAGE>
 
patent, trademark, service mark, copyright, trade secret or other proprietary
right of any third party, which such infringement would have a Material Adverse
Effect; and (iii) has not brought any action, suit or proceeding for
infringement of Intellectual Property or breach of any license or agreement
involving Intellectual Property against any third party.

          (f) DMC has secured valid written assignments from all consultants and

disclosure or appropriation of Confidential Information owned by DMC by or to a
third party has been pursuant to the terms of a written agreement between DMC
and such third party. All use, disclosure or appropriation of Confidential
Information not owned by DMC has been pursuant to the terms of a written

accordance therewith all necessary permits and licenses from all governments and

          (c) The DMC Disclosure Schedule lists the ANSI Classification and the
ANSI Standard for each DMC radioisotope source holder containing an ionizing
radiation source.  Each such product has been designed and manufactured to the
ANSI Classification and the ANSI Standard suitable according to industry
accepted practice for the required customer, environment and/or application.
Radioisotope source holder design drawings were prepared for each such product
and have been maintained by DMC and by the DMC Subsidiaries.

          2.16  Taxes.  DMC and each of the DMC Subsidiaries, and any
consolidated, combined, unitary or aggregate group for Tax purposes of which DMC
or any of the DMC Subsidiaries is or has been a member have timely filed all
material Tax Returns required to be filed by it, have paid all Taxes shown
thereon to be due and, to its knowledge, has provided adequate accruals in
accordance with generally accepted accounting principles in its financial
statements for any Taxes that have not been paid, whether or not shown as being
due on any Tax returns.  Except as disclosed in the SEC Documents, (i) no
material claim for Taxes has become a lien against the property of DMC or any of
the DMC Subsidiaries or is being asserted against DMC or any of the DMC
Subsidiaries other than liens for Taxes not yet due and payable, (ii) no audit
of any Tax Return of DMC or any of the DMC Subsidiaries is being conducted by a
Tax authority, (iii) no extension of the statute of limitations on the
assessment of any Taxes has been granted by DMC or any of the DMC Subsidiaries
and is currently in effect, and (iv) there is no agreement, contract or
arrangement to which DMC or any of the DMC Subsidiaries is a party that may
result in the payment of any amount that would not be deductible by reason of
Sections 280G, 162 or 404 of the Code.  DMC has not been and will not be
required to include any material adjustment in Taxable income for any Tax period
(or portion thereof) pursuant to Section 481 or 263A of the Code or any
comparable provision under state or foreign Tax laws as a result of
transactions, events or accounting methods employed prior to the Merger.
Neither DMC nor any of the DMC Subsidiaries is a party to any tax sharing or tax

under any such agreement.  For purposes of this Agreement, the following terms
have the following meanings: "Tax" (and, with correlative meaning, "Taxes" and
"Taxable") means (i) any net income, alternative or add-on minimum tax, gross
income, gross receipts, sales, use, ad valorem, transfer, franchise, profits,
license, withholding, payroll, employment, excise, severance, stamp, occupation,
premium, property, environmental or windfall profit tax, custom, duty or other

together with any interest or any penalty, addition to tax or additional amount
imposed by any Governmental Entity responsible for the imposition of any such
tax (domestic or foreign), (ii) any liability for the payment of any amounts of
the type described in (i) as a result of being a member of an affiliated,
consolidated, combined or unitary group for any Taxable period and (iii) any
liability for the payment of any amounts of the type described in (i) or (ii) as
a result of any express 

                                      16
<PAGE>
 
or implied obligation to indemnify any other person. As used herein, "Tax
Return" shall mean any return, statement, report or form (including, without
limitation,) estimated Tax returns and reports, withholding Tax returns and
reports and information reports and returns required to be filed with respect to
Taxes. DMC and each of the DMC Subsidiaries are in full compliance with all
terms and conditions of any Tax exemptions or other Tax-sparing agreement or
order of a foreign government and the consummation of the Merger shall not have
any adverse effect on the continued validity and effectiveness of any such Tax
exemptions or other Tax-sparing agreement or order.

          2.17  Employee Benefit Plans.

          (a) The DMC Disclosure Schedule lists, with respect to DMC, any DMC
Subsidiary and any trade or business (whether or not incorporated) which is
treated as a single employer with DMC (an "ERISA Affiliate") within the meaning
of Section 414(b), (c), (m) or (o) of the Code, (i) all material employee
benefit plans (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), (ii) each loan to a non-officer
employee in excess of $10,000, loans to officers and directors and any stock
option, stock purchase, phantom stock, stock appreciation right, supplemental
retirement, severance, sabbatical, medical, dental, vision care, disability,
employee relocation, cafeteria benefit (Code section 125) or dependent care
(Code Section 129), life insurance or accident insurance plans, programs or
arrangements, (iii) all bonus, pension, profit sharing, savings, deferred
compensation or incentive plans, programs or arrangements, (iv) other fringe or
employee benefit plans, programs or arrangements that apply to senior management
of DMC and that do not generally apply to all employees, and (v) any current or
former employment or executive compensation or severance agreements, written or
otherwise, as to which unsatisfied obligations of DMC of greater than $10,000
remain for the benefit of, or relating to, any present or former employee,
consultant or director of DMC (together, the "DMC Employee Plans").

          (b) DMC has furnished to Measurex a copy of each of the DMC Employee
Plans and related plan documents (including trust documents, insurance policies
or contracts, employee booklets, summary plan descriptions and other authorizing
documents, and, to the extent still in its possession, any material employee
communications relating thereto) and has, with respect to each DMC Employee Plan
which is subject to ERISA reporting requirements, provided copies of the Form
5500 reports filed for the last three plan years.  Any DMC Employee Plan
intended to be qualified under Section 401(a) of the Code has either obtained
from the Internal Revenue Service a favorable determination letter as to its
qualified status under the Code, including all amendments to the Code effected
by the Tax Reform Act of 1986 and subsequent legislation, or has applied to the
Internal Revenue Service for such a determination letter prior to the expiration
of 

                                      17
<PAGE>
 
the requisite period under applicable Treasury Regulations or Internal Revenue
Service pronouncements in which to apply for such determination letter and to
make any amendments necessary to obtain a favorable determination. DMC has also
furnished Measurex with the most recent Internal Revenue Service determination
letter issued with respect to each such DMC Employee Plan, and nothing has
occurred since the issuance of each such letter which could reasonably be
expected to cause the loss of the tax-qualified status of any DMC Employee Plan
subject to Code Section 401(a).

          (c) (i)  None of the DMC Employee Plans promises or provides retiree
medical or other retiree welfare benefits to any person; (ii) there has been no
"prohibited transaction," as such term is defined in Section 406 of ERISA and
Section 4975 of the Code, with respect to any DMC Employee Plan, which could
reasonably be expected to have a Material Adverse Effect; (iii) each DMC
Employee Plan has been administered in accordance with its terms and in
compliance with the requirements prescribed by any and all statutes, rules and
regulations (including ERISA and the Code), except as could not reasonably be
expected to have a Material Adverse Effect, and DMC and each DMC Subsidiary or
ERISA Affiliate have performed all obligations required to be performed by them
under, are not in default under or violation of, and have no knowledge of any
default or violation by any other party to, any of the DMC Employee Plans,
except as could not reasonably be expected to have a Material Adverse Effect;
(iv) neither DMC nor any DMC Subsidiary or ERISA Affiliate is subject to any
liability or penalty under Sections 4976 through 4980 of the Code or Title I of
ERISA with respect to any of the DMC Employee Plans; (v) all material
contributions required to be made by DMC or any DMC Subsidiary or ERISA
Affiliate to any DMC Employee Plan have been made on or before their due dates
and a reasonable amount has been accrued for contributions to each DMC Employee
Plan for the current plan years; (vi) with respect to each DMC Employee Plan, no
"reportable event" within the meaning of Section 4043 of ERISA (excluding any
such event for which the thirty (30) day notice requirement has been waived
under the regulations to Section 4043 of ERISA) nor any event described in
Section 4062, 4063 or 4041 or ERISA has occurred; and (vii) no DMC Employee Plan
is covered by, and neither DMC nor any DMC Subsidiary or ERISA Affiliate has
incurred or expects to incur any liability under Title IV of ERISA or Section
412 of the Code.  With respect to each DMC Employee Plan subject to ERISA as
either an employee pension plan within the meaning of Section 3(2) of ERISA or
an employee welfare benefit plan within the meaning of Section 3(1) of ERISA,
DMC has prepared in good faith and timely filed all requisite governmental
reports (which were true and correct as of the date filed) and has properly and
timely filed and distributed or posted all notices and reports to employees
required to be filed, distributed or posted with respect to each such DMC
Employee Plan.  No suit, administrative proceeding, action or other litigation
has been brought, or to the best knowledge of DMC is threatened, against or with
respect to any such DMC Employee Plan, including any 

                                      18
<PAGE>
 
audit or inquiry by the IRS or United States Department of Labor. Neither DMC
nor any DMC Subsidiary or other ERISA Affiliate is a party to, or has made any
contribution to or otherwise incurred any obligation under, any "multiemployer
plan" as defined in Section 3(37) of ERISA.

          (d) With respect to each DMC Employee Plan, DMC and each of its United
States DMC Subsidiaries have complied with (i) the applicable health care
continuation and notice provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and the proposed regulations thereunder and
(ii) the applicable requirements of the Family Leave Act of 1993 and the
regulations thereunder, except to the extent that any such failure to comply
could not reasonably be expected to have a Material Adverse Effect.

          (e) The consummation of the transactions contemplated by this
Agreement will not (i) entitle any current or former employee or other service
provider of DMC, any DMC Subsidiary or any other ERISA Affiliate to severance
benefits or any other payment, except as expressly provided in this Agreement,
or (ii) accelerate the time of any payments or the vesting of any options or
other benefits, or increase the amount of compensation due any such employee or
service provider.

          (f) There has been no amendment to, written interpretation or
announcement (whether or not written) by DMC, any DMC Subsidiary or other ERISA
Affiliate relating to, or change in participation or coverage under, any DMC
Employee Plan which would materially increase the expense of maintaining such
Plan above the level of expense incurred with respect to that Plan for the most
recent fiscal year included in DMC's financial statements.

          2.18  Certain Agreements Affected by the Merger.  Neither the
execution and delivery of this Agreement nor the consummation of the transaction
contemplated hereby will (i) result in any payment (including, without
limitation, severance, unemployment compensation, golden parachute, bonus or
otherwise) becoming due to any director or employee of DMC or any of its
subsidiaries, (ii) materially increase any benefits otherwise payable by DMC or
(iii) result in the acceleration of the time of payment or vesting of any such
benefits.

          2.19  Product Warranty.  Except for the amount identified as warranty
reserve on the DMC Balance Sheet, each product manufactured, sold, leased, or
delivered by DMC or the DMC Subsidiaries has been in conformity with all
applicable contractual commitments and all express and implied warranties, and
neither DMC nor any of the DMC Subsidiaries have liabilities (and there is no
basis for any present or future claim or demand against DMC or the DMC
Subsidiaries giving rise to any liability) for replacement or repair thereof
(including without limitations bringing the product into compliance with
performance 

                                      19
<PAGE>
 
guarantees), or other damages (including without limitation any refund to
customers and deduction of purchase price) and costs in connection therewith.

          2.20  Product Liability.  DMC and the DMC Subsidiaries have no
liability (and there is no basis for any present or future charge, complaint,
action, suit, proceeding, hearing, investigation, claim, or demand against any
of them giving rise to any liability) arising out of any injury to persons or
property as a result of the ownership, possession, or use of any product
manufactured, sold, leased, or delivered by DMC or the DMC Subsidiaries, except
for such liabilities that could not reasonably be expected to have a Material
Adverse Effect.  To the best knowledge of DMC, each of DMC's and the DMC
Subsidiaries' products meets all applicable product safety requirements.

          2.21  Employee Matters.  DMC and each of the DMC Subsidiaries are in
compliance in all material respects with all currently applicable laws and
regulations respecting employment, discrimination in employment, terms and
conditions of employment, wages, hours and occupational safety and health and
employment practices, and is not engaged in any unfair labor practice.  There
are no pending claims against DMC or any of the DMC Subsidiaries under any
workers compensation plan or policy or for long term disability.  Neither DMC
nor any of the DMC Subsidiaries has any material obligations under COBRA with
respect to any former employees or qualifying beneficiaries thereunder.  There
are no controversies pending or, to the knowledge of DMC, threatened, between
DMC or any of the DMC Subsidiaries and any of their respective employees, which
controversies have or could reasonably be expected to have a Material Adverse
Effect on DMC.  Neither DMC nor any of the DMC Subsidiaries is a party to any
collective bargaining agreement or other labor unions contract nor does DMC nor
any of the DMC Subsidiaries know of any activities or proceedings of any labor
union to organize any such employees.

          2.22  Interested Party Transactions.  Except as disclosed in the DMC
SEC Documents, neither DMC nor any of the DMC Subsidiaries is indebted to any
director, officer, employee or agent of DMC or any of the DMC Subsidiaries
(except for amounts due as normal salaries, bonuses or commissions and in
reimbursement of ordinary expenses), and no such person is indebted to DMC or
any of the DMC Subsidiaries (except for amounts due to normal advancements of
expenses), and there have been no other transactions of the type required to be
disclosed pursuant to Items 402 and 404 of Regulation S-K under the Securities
Act and the Exchange Act since December 31, 1994.

          2.23  Insurance.  DMC and each of the DMC Subsidiaries have policies
of insurance and bonds of the type and in amounts customarily carried by persons
conducting businesses or owning assets similar to those of DMC and the DMC
Subsidiaries.  There is no material claim pending under any of such policies 

                                      20
<PAGE>
 
or bonds as to which coverage has been questioned, denied or disputed by the
underwriters of such policies or bonds. All premiums due and payable under all
such policies and bonds have been paid and DMC and the DMC Subsidiaries are
otherwise in compliance with the terms of such policies and bonds. DMC has no
knowledge of any threatened termination of, or material premium increase with
respect to, any of such policies.

          2.24  Compliance with Laws.  Each of DMC and the DMC Subsidiaries has
complied with, are not in violation of, and have not received any notices of
violation with respect to, any federal, state, local or foreign statute, law or
regulation with respect to the conduct of its business, or the ownership or
operation of its business, except for such violations or failures to comply as
could not be reasonably expected to have a Material Adverse Effect on DMC.

          2.25  Inventory.  The inventories of DMC disclosed in the DMC Balance
Sheet and in any subsequently filed DMC SEC Documents are stated consistently
with the audited financial statements of DMC, such presentation is in accordance
with GAAP, and due provision was made to provide for all slow-moving, obsolete,
or unusable inventories to their estimated useful or scrap values and such
inventory reserves are adequate to provide for such slow-moving, obsolete or
unusable inventory and inventory shrinkage.  Since June 30, 1995, due provision
was made on the books of DMC in the ordinary course of business consistent with
past practices to provide for all slow-moving, obsolete, or unusable inventories
to their estimated useful or scrap values and such inventory reserves are
adequate to provide for such slow-moving, obsolete or unusable inventory and
inventory shrinkage.

          2.26  Accounts Receivable.  The accounts receivable disclosed in the
DMC Balance Sheet and, with respect to accounts receivable created since the
date of the DMC Balance Sheet, disclosed in any subsequently filed DMC SEC
Documents, or as accrued on the books of DMC in the ordinary course of business
consistent with past practices in accordance with generally accepted accounting
principles since the last filed DMC SEC Documents, represent and will represent
bona fide claims against debtors for sales and other charges, are not subject to
discount except for normal cash and immaterial trade discounts, and the amount
carried for doubtful accounts and allowances disclosed in each of such DMC SEC
Documents or accrued on such books is sufficient to provide for any losses which
may be sustained on realization of the receivables.

          2.27  Customers and Suppliers.  As of the date hereof, no customer
which individually accounted for more than 5% of DMC's gross revenues during the
12-month period ending August 31, 1995, and no supplier of DMC material to its
business, has cancelled or otherwise terminated, or made any written threat to
DMC to cancel or otherwise terminate its relationship with DMC, or has at any

                                      21
<PAGE>
 
time on or after June 30, 1995 decreased materially its services or supplies to
DMC in the case of any such supplier, or its usage of the services or products
of DMC in the case of such customer, and to DMC's knowledge, no such supplier or
customer intends to cancel or otherwise terminate its relationship with DMC or
to decrease materially its services or supplies to DMC or its usage of the
services or products of DMC, as the case may be.  From and after the date
hereof, no customer which individually accounted for more than 5% of DMC's gross
revenues during the 12-month period ending August 31, 1995, has cancelled or
otherwise terminated, or made any written threat to DMC to cancel or otherwise
terminate, for any reason, including without limitation the consummation of the
transactions contemplated hereby, its relationship with DMC, and to DMC's
knowledge, no such customer intends to cancel or otherwise terminate its
relationship with DMC or to decrease materially its usage of the services or
products of DMC.  DMC has not knowingly breached, so as to provide a benefit to
DMC that was not intended by the parties, any agreement with, or engaged in any
fraudulent conduct with respect to, any customer or supplier of DMC.  No
supplier of materials to DMC is the sole source of supply of any material or
materials used in any DMC product.

          2.28  Material Contracts.  The DMC Disclosure Schedule lists each
contract or agreement to which DMC is a party (i) that is required to be filed
pursuant to Item 601(b)(10) of Regulation S-K under the Securities Act (each of
which has been so filed as an Exhibit to the DMC SEC Documents), (ii) that
grants to a third party any commercial rights to exploit any of the Intellectual
Property except for licenses contained in purchase orders arising in the
ordinary course of business or (iii) the absence of which would have a Material
Adverse Effect (each, a "Material Contract'').  Each Material Contract is in
full force and effect and is enforceable against the parties thereto (other than
DMC) in accordance with its terms, except as may be limited by bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors' rights
generally (including, without limitation, the effect of statutory and other law
regarding fraudulent conveyances, fraudulent transfers and preferential
transfers) and as may be limited by the exercise of judicial discretion and the
application of principles of equity, including, without limitation, requirements
of good faith, fair dealing, conscionability and materiality (regardless of
whether considered in a proceeding in equity or at law), and no condition or
state of facts exists that, with notice or the passage of time, or both, would
constitute a default by DMC or any third party under any Material Contract.  DMC
has duly complied in all respects with the provision of each Material Contract
to which it is a party.  Without limiting the foregoing, all technology and
know-how that were required to be transferred under the agreements with
Techmetal Promotion have been transferred to DMC.

          2.29  Minute Books.  The minute books of DMC and the DMC Subsidiaries
made available to Measurex contain a complete and accurate summary of all
meetings of directors and stockholders or actions by written consent since the

                                      22

time of incorporation of DMC and the respective DMC Subsidiaries through the
date of this Agreement, and reflect all transactions referred to in such minutes
accurately in all material respects.

          2.30  Proxy Statement.  The information supplied by DMC for inclusion

Meeting") shall not, on the date the Proxy Statement is first mailed to DMC's
stockholders, at the time of the DMC Stockholders Meeting and at the Effective
Time, contain any statement which, at such time, is false or misleading with
respect to any material fact, or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they are made, not false or misleading; or omit to state any material fact
necessary to correct any statement in any earlier communication with respect to
the solicitation of proxies for the DMC Stockholders Meeting which has become
false or misleading.  If at any time prior to the Effective Time any event or
information should be discovered by DMC which should be set forth in a
supplement to the Proxy Statement, DMC shall promptly inform Measurex and Merger
Sub and prepare and disseminate such supplement.  The Proxy Statement shall
comply as to form in all material respects with the requirements of the Exchange
Act and the rules and regulations thereunder.  Notwithstanding the foregoing,
DMC makes no representation, warranty or covenant with respect to any
information supplied by Measurex or Merger Sub which is contained in any of the
foregoing documents.

          2.31  Brokers' and Finders' Fees.  DMC has not incurred, nor will it
incur, directly or indirectly, any liability for brokerage or finders' fees or
agents' commissions or investment bankers' fees or any similar charges in
connection with this Agreement or any transaction contemplated hereby.

          2.32  Opinion of Financial Advisor.  DMC has been advised in writing
by Ferris, Baker Watts, Incorporated that in such financial advisor's opinion,
as of the date hereof, the consideration to be received by the stockholders of
DMC in the Merger is fair, from a financial point of view, to the stockholders
of DMC.

          2.33  Vote Required.  The affirmative vote of the holders of a
majority of the shares of DMC Common Stock outstanding on the record date set

contemplated hereby.

          2.34  Board Approval.  The Board of Directors of DMC has unanimously
(i) approved this Agreement and the Merger, (ii) determined that the Merger is

                                      23
<PAGE>
 
fair to such stockholders and (iii) recommended that the stockholders of DMC
approve this Agreement and the Merger.

          2.35  Section 203 Not Applicable.  The Board of Directors of DMC has
taken all actions (i) to ensure that the restrictions contained in Section 203
of DGCL applicable to a "business combination" (as defined in Section 203) will
not apply to the execution, delivery or performance of this Agreement or the
Voting and Option Agreements or the consummation of the Merger or the other
transactions contemplated by this Agreement and (ii) to recommend the
appointment of the directors of the Surviving Corporation as provided in this
Agreement.

          2.36  No Government Contracts.  None of DMC or the DMC Subsidiaries
have entered into any contracts to supply products, either as a prime contractor
or as a subcontractor, to the United States government or any agency or
instrumentality thereof.

          2.37  Backlog.  The value as determined by Measurex's Backlog 
Corporate Instruction No. 511 rev. 2 of orders for products and services
received by DMC and the DMC Subsidiaries from customers but not shipped or
performed as of August 31, 1995 ("the Backlog") is $18,691,672. From August 31,
1995 through the date of this Agreement, none of the orders in the Backlog have
been cancelled.

          2.38  Right to Practice Under Instantaneous Profile Measurement
Licenses.  Excluding provisions restricting transfer and assignment, nothing in
DMC's agreements with Techmetal Promotion or the patents referenced in such
agreements shall prevent Surviving Corporation from designing, manufacturing or
selling products similar to the products made under the licenses granted in such
agreements which measure the transverse profile of a sheet by using x-rays and
any detector other than a detector which utilizes a linear array of photodiodes
which are sensitive to x-rays.

which breach has not been cured within ten business days following receipt by
the breaching party of notice of such breach; or (ii) subject to Section 7.2
hereof, the Board of Directors of DMC shall have withdrawn or modified in a
manner adverse to Measurex its approval or recommendation of the transactions
contemplated by this Agreement in order to permit DMC to execute a definitive
agreement providing for the transaction or transactions contemplated by a
Superior Proposal; provided, however, that the right to terminate this Agreement
pursuant to this Section 7.1(e) shall not be available to DMC if DMC, at such
time, is in material breach of any representation, warranty, covenant or
agreement set forth in this Agreement.

          7.2  Certain Actions Prior to Termination.  DMC shall provide to
Measurex the notice required by Section 4.2 prior to any termination of this
Agreement pursuant to Section 7.1(e)(ii) advising Measurex that the Board of
Directors of DMC has received a Superior Proposal.  At any time after the fourth
business day following such notice, DMC may terminate this Agreement as provided
in Section 7.1(e)(ii) only if the Board of Directors of DMC determines that such
Superior Proposal remains more favorable to its stockholders than the
transactions contemplated by this Agreement (which determination shall be made
in light of any revised proposal made by Measurex prior to the expiration of
such four-business day period).

          7.3  Effect of Termination.  In the event of termination of this
Agreement by Merger Sub, Measurex or DMC as provided in Section 7.1 hereof, and
except as set forth in Sections 5.4, 7.4 and this Section 7.3, this Agreement
shall forthwith become void and there shall be no liability on the part of
Merger Sub, Measurex or DMC or their respective officers or directors under this
Agreement, except to the extent that such termination results from the breach by
a party hereto of any of its representatives, warranties or covenants set forth
in this Agreement.

          (a) Whether or not the Merger is consummated, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby (including, without limitation, the fees and expenses of its advisers,
accountants and legal counsel) shall be paid by the party incurring such expense
except as set forth in Section 7.4(b).

          (b) If this Agreement is terminated pursuant to Sections 7.1(d) or

that may be available, DMC shall promptly (and in any event within two days of
receipt by DMC of written notice from Measurex) pay Measurex (by wire transfer
of immediately available funds to an account designated by Measurex) the  sum of
six hundred thousand dollars ($600,000).  The termination of this Agreement
shall not be effective until receipt by Measurex of said amount.

          (c) If this Agreement is terminated by DMC pursuant to Section
7.1(e)(i) and if Measurex is not entitled to terminate this Agreement pursuant
to Section 7.1(b) or 7.1(d)(i), then Measurex shall promptly reimburse DMC for
its out of pocket costs incurred by DMC in connection with this Agreement for
its financial advisors, legal counsel, accountants, printing costs and filing
fees.

          7.5  Amendment.  The boards of directors of the parties hereto may
cause this Agreement to be amended at any time by execution of an instrument in
writing signed on behalf of each of the parties hereto; provided that an
amendment made subsequent to adoption of the Agreement by the stockholders of
DMC shall not (i) alter or change the amount or kind of consideration to be
received on conversion of the DMC Common Stock, (ii) alter or change any term of
the Certificate of Incorporation of the Surviving Corporation to be effected by
the Merger, or (iii) alter or change any of the terms and conditions of the
Agreement if such alteration or change would adversely affect the holders of DMC
Common Stock.

          7.6  Extension; Waiver.  At any time prior to the Effective Time any
party hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto and (iii)
waive compliance with any of the agreements or conditions for the benefit of

                                   ---------


                       VOTING AND STOCK OPTION AGREEMENT


          THIS VOTING AND STOCK OPTION AGREEMENT (this "Agreement"), is made and
entered into as of September 16, 1995, by and between __________________
("Grantor"), and MEASUREX CORPORATION, a Delaware corporation ("Measurex").

          WHEREAS, Grantor is an officer, director or principal stockholder of
Data Measurement Corporation, a Delaware corporation ("DMC"); and

          WHEREAS, Measurex and DMC propose to enter into an Agreement and Plan
of Reorganization and related agreements dated as of the date hereof (the
"Merger Agreement"; capitalized terms not defined herein shall have the meanings
set forth in the Merger Agreement), providing for, among other things, the
merger of a wholly owned subsidiary of Measurex with and into DMC (the "Merger")
upon the terms described therein; and

          WHEREAS, as an inducement to Measurex's willingness to enter into the
Merger Agreement and as a condition to Measurex's obligation to effect the
Merger, Grantor has agreed to grant Measurex the Option described in this
Agreement.

          NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants, and agreements set forth herein and in
the Merger Agreement, Grantor and Measurex agree as follows:

          1.  Agreement to Retain Stock.

          (a) Transfer and Encumbrance.  Grantor agrees not to transfer, sell,
exchange, pledge or otherwise dispose of or encumber any shares of DMC Common
Stock owned by Grantor (the "Stock") or any New Stock (as defined in Section
1(b) below) or to make any offer or agreement relating thereto, at any time
prior to the Expiration Date (as defined in Section 1(c) below) except upon the
exercise of the Option (as defined below) by Measurex; provided, however, that
any pledge on or other encumbrance in respect of any of the Stock existing as of
the date hereof shall be permitted to remain in existence and shall not be
deemed a breach of this Section 1(a).

          (b) New Stock.  Grantor agrees that any shares of DMC Common Stock
that Grantor purchases or with respect to which Grantor otherwise acquires
record or beneficial ownership after the date of this Agreement and prior to the

                                      43
<PAGE>
 
Expiration Date ("New Stock") shall be subject to the terms and conditions of
this Agreement to the same extent as if they had originally constituted Stock.
Grantor is the holder of DMC stock options and/or convertible debentures, all of
which are fully exercisable or convertible into DMC Common Stock.  In the event
Measurex gives Grantor notice of the exercise of its option under this Agreement
and requests Grantor to do so, Grantor will exercise his DMC stock options
and/or convert his convertible debentures and the stock he acquires will be
included in New Stock.

          (c) Expiration Date.  For purposes of this Agreement, "Expiration
Date" shall mean the earliest of (i) such date and time as the Merger shall
become effective in accordance with the terms and provisions of the Merger
Agreement, (ii) the date on which the Merger Agreement is terminated pursuant to
Sections 7.1(a), (b) or (c) of the Merger Agreement or Measurex's failure to
transmit to the Exchange Agent the Merger Consideration in accordance with the
terms of the Merger Agreement or the failure of the Merger to be consummated for
reasons other than DMC's breach or default under the Merger Agreement on or
before January 31, 1996, (iii) sixty (60) days after termination of the Merger
Agreement for any other reason except for a termination following DMC's breach
or default under the Merger Agreement or (iv) six months after the date of this
Agreement.

          2.  Agreement to Vote Stock.  At every meeting of the stockholders of 
DMC called with respect to any of the following, and at every adjournment
thereof, and on every action or approval by written consent of the stockholders
of DMC with respect to any of the following, Grantor shall vote the Stock and
any New Stock: (i) in favor of approval of the Merger Agreement and the Merger
and any matter that could reasonably be expected to facilitate the Merger; and
(ii) against approval of any proposal made in opposition to or in competition
with the consummation of the Merger and the Merger Agreement, against any
merger, consolidation, sale of substantial assets, sale of shares of capital
stock, reorganization, recapitalization or similar transactions involving DMC or
its subsidiaries, with any party other than Measurex or one of its affiliates
and against any liquidation or winding up of DMC (each of the foregoing is
referred to as an "Opposing Proposal").

          3.  Irrevocable Proxy.  In order to effect the intent of paragraph 2, 
concurrently with the execution of this Agreement Grantor shall deliver to the
members of the Board of Directors of Measurex a proxy in the form attached
hereto as Annex A (the "Proxy"), which shall be irrevocable to the extent
provided by the General Corporation Law of the State of Delaware, covering the
Stock and New Stock.

          4.  No Proxy Solicitations.  Except for actions taken by Grantor 
solely in Grantor's capacity as a member of the Board of Directors of DMC, if
applicable, in order to comply with applicable law as advised in writing by
independent legal counsel, Grantor will not, and will not permit any entity
under Grantor's control, to: 

                                      44
<PAGE>
 
(i) solicit proxies or become a "participant" in a "solicitation" (as such terms
are defined in Regulation 14A under the Exchange Act) with respect to an
Opposing Proposal or otherwise encourage or assist any party in taking or
planning any action that would compete with, restrain or otherwise serve to
interfere with or inhibit the timely consummation of the Merger in accordance
with the terms of the Merger Agreement; (ii) initiate a stockholders' vote or
action by written consent of DMC stockholders with respect to an Opposing
Proposal; or (iii) become a member of a "group" (as such term is used in Section
13(d) of the Exchange Act) with respect to any voting securities of DMC with
respect to an Opposing Proposal.

          5.  Grant of Option.  Subject to the terms and conditions set forth 
herein, Grantor hereby grants to Measurex an irrevocable option (the "Option")
to purchase all of the Stock, constituting ______________ shares, owned by
Grantor as of the date hereof and any New Stock hereafter acquired by Grantor
(collectively, the "Option Stock"), at a purchase price of $18.625 per share of
Option Stock (the "Purchase Price").

          6.  Exercise of Option.

          (a) Measurex may exercise the Option for all Option Stock at any time 
prior to the Expiration Date.

          (b) In the event Measurex wishes to exercise the Option, it shall send
to Grantor a written notice (the date of which being herein referred to as the
"Notice Date") specifying a place and date not earlier than three business days
nor later than 15 business days after the Notice Date for the closing of such
purchase (the "Closing Date"); provided that if the closing of the purchase and
sale pursuant to the Option (the "Closing") cannot be consummated by reason of
any applicable judgment, decree, order, law or regulation, the period of time
that otherwise would run pursuant to this sentence shall run instead from the
date on which such restriction on consummation has expired or been terminated;
and, provided further that, without limiting the foregoing, if prior
notification to or approval of any regulatory authority is required in
connection with such purchase, Measurex and, if applicable, Grantor shall
promptly file the required notice or application for approval and shall
expeditiously process the same (and Grantor shall cooperate with Measurex in the
filing of any such notice or application and the obtaining of any such
approval), and the period of time that otherwise would run pursuant to this
sentence shall run instead from the date on which, as the case may be, (i) any
required notification period has expired or been terminated or (ii) such
approval has been obtained, and in either event, any requisite waiting period
has passed.

          (c) Notwithstanding Section 7(b), in no event shall the Closing Date
be more than 12 months after the related Notice Date, and if the Closing Date
shall not have occurred within 12 months after the related Notice Date due to
the failure 

                                      45
<PAGE>
 
to obtain any required approval, the Option and the exercise thereof effected on
the Notice Date shall be deemed to have expired.

          7.  Payment for and Delivery of Certificates.

          (a) On the Closing Date, Measurex shall pay to Grantor by wire
transfer to a bank account designated by Grantor an amount equal to the Purchase
Price multiplied by the number of shares of Option Stock to be purchased on such
Closing Date.

          (b) At the Closing, simultaneously with the delivery of funds as
provided in Section 7(a), Grantor shall deliver to Measurex a certificate or
certificates representing the Option Stock to be purchased at such Closing,
which Option Stock shall be fully paid and non-assessable and free and clear of
all liens, claims, charges, and encumbrances of any kind whatsoever, and
Measurex shall deliver to Grantor a certificate agreeing that Measurex shall not
offer to sell or otherwise dispose of such Option Stock in violation of
applicable law or this Agreement.

          8.  Adjustment upon Changes in Capitalization, Etc. In the event of 
any change in DMC Common Stock by reason of a stock dividend, stock split,
recapitalization, combination, exchange of shares, or similar transaction, the
type and number of shares or securities subject to the Option, and the Purchase
Price therefor, shall be adjusted appropriately, and proper provision shall be
made in the agreements governing such transaction, so that Measurex shall
receive upon exercise of the Option the same class and number of outstanding
shares or other securities or property that Measurex would have received in
respect of DMC Common Stock if the Option had been exercised immediately prior
to such event, or the record date therefor, as applicable.

          9.  Representations of Grantor.  Grantor represents and warrants to 
Measurex that:

          (a) Grantor has full legal capacity to execute this Agreement, and
this Agreement will be binding upon the heirs, personal representatives,
successors and assigns of Grantor.

          (b) Grantor is the lawful owner of the Option Stock, of record and
beneficially, free and clear of all liens, charges, pledges, security interests,
options, claims or other encumbrances, and has full right, power and authority
to sell, assign, transfer and deliver the Option Stock to be sold by Grantor to
Measurex upon exercise of the Option; and upon the delivery of such Option Stock
to Measurex hereunder, Measurex shall obtain good and valid title thereto free
and 

                                      46
<PAGE>
 
clear of all liens, charges, pledges, security interests, options, claims or
other encumbrances.

          (c) The execution, delivery and performance by Grantor of this
Agreement, and compliance by Grantor with the provisions hereof will not (i)
violate any provision of any current law, statute, rule or regulation applicable
to Grantor, or any ruling, writ, injunction, order or decree of any court,
administrative agency or other governmental body applicable to Grantor or (ii)
conflict with or result in a breach of any provisions or constitute (with due
notice or lapse of time or both) a default under any agreement, contract or
instrument to which Grantor is a party or by which Grantor or any of the Option
Stock is bound.

          10.  Miscellaneous.

          (a) Expenses.  Except as otherwise provided in the Merger Agreement,
each of the parties hereto shall bear and pay all costs and expenses incurred by
it or on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own counsel.

          (b) Waiver and Amendment.  Any provision of this Agreement may be
waived at any time by the party that is entitled to the benefits of such
provision.  This Agreement may not be modified, amended, altered or supplemented
except upon the execution and delivery of a written agreement executed by the
parties hereto.

          (c) Entire Agreement:  No Third-Party Beneficiary:  Severability.
Except as otherwise set forth in the Merger Agreement, this Agreement (a)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, between the parties with respect to the
subject matter hereof and (b) is not intended to confer upon any person other
than the parties hereto any rights or remedies hereunder.  If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated.

          (d) Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware without regard to any
applicable conflicts of law rules.

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

                                   ---------

                               PHYSICAL INVENTORY


     A physical count of DMC's and the DMC Subsidiaries' inventory, (the "DMC
Inventory") will be taken prior to the Closing Date in order to determine the
Additional Inventory Reserve as defined in this Exhibit.  At the time of such
count inventory reserves will be established in the following manner.  A reserve
will be established equal to the value of all items in the DMC Inventory (prior
to any reserves which may be reflected on the DMC Balance Sheet) which are
damaged to the point that they are not economically repairable or which are
obsolete (obsolete as it applies to an item in the DMC Inventory shall mean that
it could not reasonably be expected that such items could be used in a newly
manufactured product or as a part for service), (such items the "Damaged and
Obsolete Inventory," and  the value of such reserve, the "Damaged and Obsolete
Inventory Reserve").  After the Damaged and Obsolete Inventory has been removed
from the DMC Inventory a reserve will be established equal to 50% of the value
of all items in remaining DMC Inventory (prior to any reserves which may be
reflected on the DMC Balance Sheet) which have had no use for the last twelve
months prior to the date of this Agreement, (such items the "Inactive
Inventory," and the value of such reserve the "Inactive Inventory Reserve").
After removing the Damaged and Obsolete Inventory and the Inactive Inventory
from the DMC Inventory a reserve will be established on the remaining DMC
Inventory items (such items the "Current Inventory" and the value of such
reserve the "Current Inventory Reserve") based upon the last twelve month's
usage of each item prior to the date of this Agreement or, for items introduced
into inventory for the first time within the last twelve months, the twelve
month forecasted usage for such recently introduced items, (the "Annual Usage").
For all items in the Current Inventory with quantities in excess of the Annual
Usage a reserve will be established equal to the sum of:  1) 25% of value of
such items in excess of the Annual Usage but less than twice the Annual Usage;
2) 50% of the value of such items in excess of two times the Annual Usage but
less than three times the Annual Usage; 3) 100% of the value of such items in
excess of three times the Annual Usage (all the above values prior to any
reserves which may be reflected on the DMC Balance Sheet).  The sum of the
Damaged and Obsolete Inventory Reserve, the Inactive Inventory Reserve and the
Current Inventory Reserve less the inventory reserve as reported on the DMC
Balance Sheet shall equal to the Additional Inventory Reserve.
