3.2 COMPANY STOCK; OPTIONS.

(a) CONVERSION OF STOCK. At the Effective Time, each share of Company Common Stock that is issued and outstanding immediately prior to the Effective Time, exclusive of shares held by Dissenting Shareholders, shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive in cash without interest an amount equal to (i) U.S. $30,000,000 plus Options Cash divided by (ii) Outstanding Shares (the "Cash Consideration").

(b) CANCELLATION OF COMPANY COMMON STOCK. At the Effective Time, as a result of the Merger and without any action on the part of the holders thereof, all shares of Company Common Stock outstanding at the Effective Time shall cease to be outstanding, shall be canceled and retired and shall cease to exist, and each holder of shares of Company Common Stock shall thereafter cease to have any rights with respect to such shares of Company Common Stock, except the right to receive upon the surrender of a certificate representing such shares of Company Common Stock (a "Certificate") an amount equal to (i) the number of shares of Company Common Stock set forth on the Certificate, multiplied by (ii) the Cash Consideration.

(c) TREASURY SHARES AND SHARES HELD BY SUBSIDIARIES. At the Effective Time, as a result of the Merger and without any action on the part of Parent, Merger Sub or the Company, any and all shares of Company Common Stock issued and held in the Company's treasury shall cease to be outstanding, shall be canceled and retired without payment of any consideration therefor and shall cease to exist.

(d) OPTIONS.

(i) At the Effective Time, as a result of the Merger and without any action on the part of holder thereof, each option to purchase Company Common Stock granted by the Company (collectively, "Company Options") under one of its stock option plans (collectively, "Company Option Plans") that remains outstanding and unexercised as of the Effective Time, whether or not vested or exercisable, shall be assumed by Parent and shall be converted into an option to purchase Parent Common Stock (collectively, "Substituted Options"); provided, however that, in the event the Option Exchange Ratio (as calculated in subparagraph (ii) below) is greater than 0.553, Parent shall have the right to require the Company

to cause the Company Options granted under the Engineering Measurements Company 1991 Incentive Plan and the Engineering Measurements Company 1997 Incentive Plan (the "Incentive Plans") that are outstanding immediately prior to the Closing to be cancelled pursuant to Section 14(e) of each Incentive Plan and to pay the consideration required by such Sections 14(e) based upon the Cash Consideration. If Parent requires the Company to cause the Company Options granted under the Incentive Plans to be cancelled, then (A) Parent shall not be required to assume the Company Options cancelled, and (B) if the Company does not have sufficient cash available to pay the consideration required by Section 14(e) of each of the Incentive Plans, Parent shall advance the necessary funds to the Company.

(ii) Subject to subsection 3.2(d)(iii) below, (A) each Substituted Option shall be exercisable for the number of shares of Parent Common Stock (rounded down to the nearest whole share) equal to the product obtained by multiplying the number of shares of Company Common Stock covered by the related Company Option immediately prior to the Effective Time by a fraction (the "Option Exchange Ratio"), the numerator of which is the Cash Consideration and the denominator of which is the closing price per share of Parent Common Stock reported on the Nasdaq National Market on the trading day preceding the Stockholders' Meeting; (B) the option price per share of Parent Common Stock thereafter shall be equal to the quotient (rounded up to the nearest whole cent) obtained by dividing the exercise price per share of Company Common Stock subject to the related Company Option in effect immediately prior to the Effective Time by the Option Exchange Ratio); and (C) each Substituted Option shall be exercisable on the same terms and subject to the same conditions as had been applicable to the related Company Option, except to the extent the number of shares and exercise price per share have been adjusted pursuant to (A) and (B), respectively, of this subsection 3.2(d)(ii).

(iii) It is the intention of the parties that Company Options that qualified as incentive stock options, within the meaning of Section 424 of the Code ("ISOs"), immediately prior to the Effective Time, be converted, when assumed by Parent, into Substituted Options that qualify as ISOs immediately following the Effective Time, to the extent permitted by Section 424 of the Code and applicable terms of the Company Option Plans. In furtherance of such intention, the formulae, terms and conditions set forth in subsection 3.2(d)(ii) above may be applied to, or modified for, such Substituted Options as deemed reasonably necessary by Parent, so long as any such application or modification does not materially reduce the benefit of the Substituted Option to the holder thereof.

(iv) The Company's Employee Stock Purchase Plan (the "Stock Purchase Plan") shall be terminated prior to the Closing. All funds invested in the Stock Purchase Plan but not used by employees to purchase stock thereunder prior to the Effective Time shall be transferred or otherwise credited to employees of the Company such that, following the Effective Time, each such employee shall have purchase rights under Parent's stock purchase plans substantially similar to those existing under the Stock Purchase Plan immediately prior to the Effective Time.

(v) On or prior to the Effective Time, Parent shall file with the Commission a Registration Statement on Form S-3 or Form S-8, as determined by Parent in its sole discretion, relating to the issuance of the Parent Common Stock underlying the Substituted Options (a "Registration Statement") or shall cause such Parent Common Stock to be included in

an effective Registration Statement on Form S-8 relating to one or more of Parent's stock option plans (collectively, "Parent Option Plans"). So long as any Substituted Options remain outstanding, Parent shall use its reasonable best efforts to maintain the effectiveness of any Registration Statement(s) related to the Substituted Options (and to maintain the current status of the prospectus or prospectuses related thereto). At or prior to the Effective Time, Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon exercise of the Substituted Options. To the extent required by the relevant market or exchange, Parent shall list or qualify all such shares for trading on the principal market or exchange on which Parent Common Stock is traded from time to time.

3.3 PAYING AGENT.

(a) At or prior to the Effective Time, Parent shall enter into an agreement with a bank or trust company selected by Parent to act as the paying agent for the Merger (the "Paying Agent").

(b) At or prior to the Effective Time, Parent shall supply or cause to be supplied to or for the account of the Paying Agent in trust for the benefit of the holders of Company Common Stock the funds necessary to make the payments contemplated in Section 3.2(a). Such funds shall be invested by the Paying Agent as directed by Parent in accordance with Parent's investment policy. No interest will be paid or accrued on the cash payable to holders of Company Common Stock.

(c) Promptly after the Effective Time, Parent shall mail or cause to be mailed to each holder of Company Common Stock a letter of transmittal, in a typical form (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 Paying Agent) and instructions for surrender of the Certificates. Upon surrender to the Paying Agent of a holder's Certificate, together with such letter of transmittal duly executed, such holder of Common Stock shall be entitled to receive in exchange therefor a cash payment equal to such holder's Merger Consideration, and such Certificate so surrendered shall forthwith be canceled.

(d) In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, the appropriate Merger Consideration may be issued to such transferee of such Company Common Stock, if the Certificate representing such Company Common Stock is presented to the Paying Agent, accompanied by all documents, in form and substance reasonably satisfactory to Parent and the Paying Agent, required to evidence and effect such transfer of Company Common Stock and to evidence that any applicable stock transfer taxes have been paid. There shall be no transfers on the transfer records of the Company, at or after the Effective Time, of shares of Company Common Stock which were outstanding immediately prior to the Effective Time. Until surrendered in accordance with the provisions of this Section 3.3, from and after the Effective Time each Certificate shall be deemed to represent the right to receive a cash payment equal to the holder's Merger Consideration.

(e) Any portion of the funds supplied to the Paying Agent which remains undistributed to the former stockholders of the Company for twelve months after the Effective

Time shall be delivered to Parent, upon demand of Parent, and any such former stockholders who have not theretofore complied with this Section 3.3 shall thereafter look only to Parent (subject to abandoned property, escheat and other similar laws) only as general creditors of Parent with respect to any consideration set forth in Section 3.2(a) that may be payable upon surrender of their Certificates.

(f) None of Parent, the Company, the Surviving Corporation, the Paying Agent or any other person shall be liable to any former stockholder of the Company for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

3.4 LOST CERTIFICATES. In the event any Certificate shall have been lost, stolen or destroyed, upon the making and delivery of an affidavit (in form and substance satisfactory to the Surviving Corporation) of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

3.5 DISSENTING SHARES.

(a) Dissenting Shares shall not be converted into or represent the right to receive the consideration set forth in Section 3.2(a), unless such Dissenting Shareholder's right to appraisal shall have ceased in accordance with Article 113 of the CBCA. If such Dissenting Shareholder has so forfeited or withdrawn his, her or its right to appraisal of Dissenting Shares, then (i) as of the occurrence of such event, such holder's Dissenting Shares shall cease to be Dissenting Shares and shall be converted into and represent the right to receive the Merger Consideration in respect of such shares of Company Common Stock pursuant to Section 3.2(a), and (ii) promptly following the occurrence of such event, and in any case within ten (10) days of such event, Parent shall deposit with the Paying Agent the amount of Merger Consideration to which such holder is entitled pursuant to Section 3.2(a).

(b) The Company shall give Parent (i) prompt notice of any written demands for appraisal of any shares of Company Common Stock, withdrawals of such demands, and any other instruments that relate to such demands received by the Company, and (ii) after due consultation with the Company, the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the CBCA.

(b) The Company acknowledges that the agreements contained in this

8.6 EXTENSION; WAIVER. At any time prior to the Effective Time, any party hereto, by action taken by its Board of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions for the benefit of such party contained herein.
