Item 2. Acquisition or Disposition of Assets On February 14, 2002, and as amended effective February 26, 2002, Itron, Inc. ("Itron"), LS Combination, Inc. ("Merger Sub"), a Washington corporation and a wholly-owned subsidiary of Itron, and LineSoft Corporation, a Washington corporation ("LineSoft") entered into an Agreement and Plan of Reorganization (the "Merger Agreement") pursuant to which Merger Sub will be merged into LineSoft (the "Merger") with LineSoft surviving as a wholly-owned subsidiary of Itron. The Merger is expected to be completed on or about March 11, 2002. The Merger Agreement contemplates that LineSoft will be merged into Itron within three months of the effective time of the Merger (the "Step-Two Merger", and, together with the Merger, the "Mergers"). The completion of the Mergers is subject to customary conditions, including the approval of the holders of two-thirds of the LineSoft common stock outstanding as of February 14, 2002. At the effective time of the Merger, the capital stock of Merger Sub and LineSoft, other than dissenting shares, shall be converted as follows: (a) all issued and outstanding shares of capital stock of Merger Sub shall be converted into and become one fully paid and nonassessable share of common stock, par value $.001 per share, of LineSoft; and (b) each issued and outstanding share of capital stock of LineSoft shall be converted automatically into the right to receive: (i) for shareholders who are not "accredited investors" within the meaning of Rule 501 of Regulation D promulgated under the Securities Act of 1933, as amended (the "Securities Act"), an amount of cash equal to approximately $0.955; (ii) for shareholders who are "accredited investors" within the meaning of Rule 501 of Regulation D promulgated under the Securities Act (other than OCM/GFI Power Opportunities Fund, L.P. ("GFI")), an amount of cash and a fraction of one share of Itron common stock that, in the aggregate, have a value equal to approximately $0.955; and (iii) for GFI, an amount of cash, a fraction of one share of Itron common stock and certain earnout payments, if any, calculated and paid in accordance with the provisions of the Merger Agreement that, in the aggregate, have a value equal to approximately $0.955. Accredited investors (including GFI) will receive cash in lieu of fractional shares of Itron common stock that would otherwise be issued as part of the total consideration to be exchanged for such investors' shares of LineSoft stock. The Merger Agreement provides that the value of Itron common stock to be issued in connection with the Merger is subject to a minimum per share value of $22, and a maximum per share value of $32. The source of the cash portion to be used by Itron to accomplish the acquisition will be Itron's current assets, including Itron's cash and cash equivalents, and short-term investments. Also on February 14, 2002, both GFI, the largest LineSoft shareholder, and Fred A. Brown, the second-largest LineSoft shareholder, together representing 74.6% of the issued and 2

outstanding LineSoft capital stock, entered into support agreements ("Support Agreements") with Itron whereby each has granted an irrevocable proxy to a representative of Itron to vote his/its respective shares: (a) in favor of adoption and approval of the Merger Agreement and all transactions relating thereto or contemplated thereby, and (b) against any proposal by a party other than Itron or its affiliate to merge or consolidate with LineSoft or any subsidiary of LineSoft or to sell all or substantially all the assets of or any sales of equity interest in LineSoft or any subsidiary of LineSoft. The foregoing descriptions of the Mergers, the Merger Agreement, and the Support Agreements are qualified in their entirety by reference to the text of the Merger Agreement and the forms of the Support Agreements which are attached hereto as Exhibits 2.1, 4.1 and 4.2 respectively and are incorporated herein by reference. On February 15, 2002, Itron issued a press release announcing the Merger Agreement, the Support Agreements and the related transactions. The press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

To the extent that the Estimated Net Working Capital Adjustment is a decrease in excess of Three Million Dollars ($3,000,000) (such excess, an "Initial Excess Decrease"), Itron shall withhold from the Initial ----------------------- Merger Consideration an amount of cash equal to such Initial Excess Decrease, and Itron shall add such cash and Itron Common Shares to the Escrow provided for in Section 3.1(d) above.

The Final Closing Statements shall be prepared according to GAAP, consistent with the Company's past practices through the Effective Time of the Merger, except for the adjustments set forth on Schedule 3.1(e), -------------- which shall be applied to calculate the final Net Working Capital Adjustment and shall be reflected in one or more footnotes and supplemental schedules to such statements. A separate schedule attached to the Final Closing Statements shall contain the calculation of the final Net Working Capital Adjustment. The Itron Final Closing Statements shall be promptly delivered to each of the Shareholders' Representatives as soon as they are available for their review and comment, and Itron and the Shareholders' Representatives shall thereafter attempt to reach agreement on the Final Closing Statements. If the Shareholders' Representatives and Itron are unable to agree on the Final Closing Statements, then the Shareholders' Representatives shall present any objections or comments in writing to Itron no later than twenty (20) days after their receipt of the Final Closing Statements, specifying in reasonable detail any objections thereto. Itron and the Shareholders' Representative shall have access to the Company's and Itron's work papers used in the preparation of the Preliminary Closing Balance Sheet and Final Closing Statements. If Itron and the Shareholders' Representatives are unable to resolve informally matters raised by such comments or objections, the matter shall be resolved by the Accounting Arbitrator(s) in accordance with the process set forth in Section 3.2(b). -------------- (iii) To the extent that the Net Working Capital Adjustment (as finally determined in accordance with the provisions set forth above (a "Final NWCA Determination") is an increase of greater than ------------------------ Three Million Dollars ($3,000,000) (such excess over $3,000,000 being a "Final Excess Increase"), then, within five (5) Business Days after --------------------- such Final NWCA Determination, Itron shall deposit with the Escrow Agent -15-

an amount of cash equal to such Final Excess Increase, less any cash added to the Escrow as an Initial Excess Increase, if any, (a "Final ----- NWCA Payment"). Within two (2) days after a Final NWCA Payment is ------------ deposited in the Escrow pursuant to this Section 3.1(e)(iii), such ------------------ Final NWCA Payment, plus any Initial Excess Increase or any Initial Excess Decrease, as applicable, shall be released from the Escrow to the Shareholders' Representatives, whereupon it shall be and paid at and by the direction of the Shareholders' Representatives to the former Company Shareholders in proportion to their receipt of the Initial Merger Consideration in accordance with Exhibit D. --------- (iv) To the extent that a Final NWCA Determination results in a Net Working Capital Adjustment that is zero or a Final Excess Increase that is less than the amount of any Initial Excess Increase, if any (such difference, an "NWCA Overpayment"), then, within five (5) Business Days ---------------- following a Final NWCA Determination, (x) Itron may, pursuant to the Escrow Agreement, instruct the Escrow Agent to transfer an amount of cash equal to such NWCA Overpayment to Itron, and (y) the remainder of such Initial Excess Increase shall be released from the Escrow to the Shareholders' Representatives, whereupon it shall be paid at and by the direction of the Shareholders' Representatives to the former Company Shareholders in proportion to their receipt of the Initial Merger Consideration in accordance with Exhibit D. --------- (v) To the extent that a Final NWCA Determination results in aNet Working Capital Adjustment that is a decrease of more than Three Million Dollars ($3,000,000), (the amount of such decrease in excess of $3,000,000 being a "Final Excess Decrease"), then within five (5) --------------------- business days following such Final NWCA Determination, Itron may, pursuant to the Escrow Agreement, instruct the Escrow Agent to transfer an amount of cash equal to such Final Excess Decrease, plus the entire amount of any Initial Excess Increase previously deposited into the Escrow by Itron, to Itron. (vi) To the extent that a Final NWCA Determination results in a Net Working Capital Adjustment that is zero or a Final Excess Decrease that is less than the amount of an Initial Excess Decrease, if any (such difference, an "NWCA Underpayment"), then, within five (5) business ----------------- days following a Final NWCA Determination, such NWCA Underpayment shall be released from the Escrow to the Shareholders' Representatives, whereupon it shall be paid at and by the direction of the Shareholders' Representatives to the former Company Shareholders in proportion to their receipt of the Initial Merger Consideration in accordance with Exhibit D. --------- (vii) The adjustments pursuant to the Net Working Capital Adjustments in this Section 3.1(d) shall be treated as an increase or a ------------- decrease in the Initial Merger Consideration. (f) Dissenter's Rights. Any holder of any Company Common Shares that ------------------ are outstanding on the record date for the determination of the Company Shareholders entitled to vote for or against the Merger who did not vote such shares in favor of the Merger, or sign and deliver a written consent thereto with respect to such shares (the Company Common Shares then outstanding that are not thus voted or as to which such consents are not signed and delivered are -16-

referred to as "Eligible Dissenting Shares"), will be entitled to exercise -------------------------- dissenters' rights pursuant to Chapter 23B.13 et seq. of the WBCA ("Chapter ------- 23B.13") with respect to such Eligible Dissenting Shares; provided, that such - ------ -------- holder meets all the requirements of Chapter 23B.13 with respect to such shares. SECTION 3.2. Earnout Payments. ---------------- (a) Determination of LineSoft Revenue. For each of the fiscal years --------------------------------- ended December 31, 2002, 2003 and 2004 (each such fiscal year, an "Earnout ------- Period," except that the Earnout Period for 2002 shall commence on the Closing - ------ Date), Itron shall calculate the annual revenue of the LineSoft Product Line (the "LineSoft Revenue") for the Earnout Period then ended in the manner ---------------- specified in Schedule 3.2 attached hereto. The LineSoft Revenue shall be ------------ determined by Itron using the same information used in compiling the audited financial statements of Itron and related work papers and will be in accordance with GAAP consistently applied. During each Earnout Period, as soon as practicable after the end of fiscal quarter, but no later than forty-five (45) days thereafter, Itron shall provide GFI with a statement describing the LineSoft Revenue as of the end of such quarter and for such Earnout Period to date, prepared in accordance with this Section 3.2 and with GAAP consistently ----------- applied, setting forth in reasonable detail the calculations relating to such determination and signed by the principal financial officer of Itron. No later than the thirty-first (31st) day of March immediately following the end of each Earnout Period, Itron shall deliver to GFI (i) a written calculation of the annual LineSoft Revenue, which written calculation shall specify in reasonable detail the calculation of the annual LineSoft Revenue with respect to such Earnout Period, taking into consideration any change in circumstances as provided in subsection (e) hereof and the resulting Earnout Payment, if any, calculated in accordance with this Agreement and (ii) the Earnout Payment, if any, due to GFI pursuant to such written calculation. Itron shall also cause Deloitte & Touche, LLP or such other nationally recognized accounting firm designated at Itron's sole discretion (the "Itron Accountants") to confirm that ----------------- the calculations of the annual LineSoft Revenue are in accordance with the provisions of Schedule 3.2 and that the procedures performed for calculating the ------------ annual LineSoft Revenue are in accordance with GAAP consistently applied. (b) Notification of Annual LineSoft Revenue Dispute. Upon receipt of ----------------------------------------------- such written calculation of the annual LineSoft Revenue and Earnout Payment, if any, from Itron pursuant to Section 3.2(a), GFI shall have thirty (30) Business ------------- Days in which to object in writing to Itron with respect to Itron's written calculation of the annual LineSoft Revenue and the amount of the Earnout Payment paid to GFI, if any (the "LineSoft Revenue Dispute Notice"). During the ------------------------------- foregoing period, and at its sole discretion, GFI may cause a nationally recognized accounting firm designated at its sole discretion (the "GFI --- Accountants") to review the written calculation of the LineSoft Revenue as - ----------- provided by Itron. In the event that GFI fails to object to Itron's written calculation of the annual LineSoft Revenue and the amount of the Earnout Payment paid to GFI, if any, within the foregoing period, it shall be deemed conclusive and binding on all parties. In the event that GFI provides Itron with a timely LineSoft Revenue Dispute Notice, then GFI and Itron shall work together in good faith to reach an agreement on the appropriate Earnout Payment. If within twenty (20) Business Days after Itron's receipt of the LineSoft Revenue Dispute Notice, Itron and GFI have not reached an agreement, the parties shall engage the Accounting Arbitrator to calculate the amount of the Earnout Payment. If the parties are unable -17-

to agree upon one Accounting Arbitrator, each shall appoint an Accounting Arbitrator and these appointees shall appoint a third Accounting Arbitrator (collectively, the "Accounting Arbitrators"), in which case the determination of ---------------------- the amount of the Earnout Payment shall be made by a majority decision of the Accounting Arbitrators.

The Accounting Arbitrator(s) shall be directed to make a determination of the Earnout Payment within forty-five (45) days of engagement. Payment by Itron or GFI, as applicable, of the difference between the Earnout Payment, if any, paid by Itron pursuant to 3.2(a) and the amount of the Earnout Payment as determined by the Accounting Arbitrator(s) (the "Earnout Correction Amount") shall be due within ten (10) days after the ------------------------- resolution of any such dispute. In addition, the party paying the Earnout Correction Amount, if any, shall on such tenth (10/th/) day pay interest then accrued on the Earnout Correction Amount, from the thirty-first (31st) of March following the end of such Earnout Period until the date that such Earnout Correction Amount, as determined by the Accounting Arbitrator(s), is actually paid, calculated at ten (10%) per annum, simple interest. Itron and GFI shall pay the costs and expenses of their own accountants and attorneys and shall bear equally the expense of the Accounting Arbitrator; provided, however, that, (X) -------- ------- if the Accounting Arbitrator determines that the Earnout Payment is at least ten percent (10%) greater than the amount that was initially paid by Itron to GFI, then Itron shall pay all fees and expenses with respect to the Itron Accountants, the GFI Accountants and the Accounting Arbitrator(s) as well as all reasonable attorneys' fees of the parties, and (Y) if the Accounting Arbitrator determines that the Earnout Payment is at least ten percent (10%) less than the amount that was initially paid by Itron to GFI, then GFI shall pay all fees and expenses with respect to the Itron Accountants, the GFI Accountants and the Accounting Arbitrator(s) as well as all reasonable attorneys' fees of the parties. (c) Breach of Covenants regarding Operation of LineSoft Product Group. ----------------------------------------------------------------- In the event that GFI alleges in its LineSoft Revenue Dispute Notice an entitlement to a greater Earnout Payment because of a breach of Itron's covenants in Section 6.12 hereof, and the parties are unable to resolve the ------------ dispute within the twenty (20) Business Day resolution period referenced in Section 3.2(b), then the dispute shall be resolved in accordance with Section ------- 10.3(b) (including, but not limited to, the payment of interest). - ------ (d) Payment of Earnout Payment. Each Earnout Payment, if any, shall be -------------------------- paid by Itron to GFI, or to one or more permitted assignees of GFI as specified in writing by GFI to Itron. The portion of any Earnout Payment that is treated as interest for federal tax purposes shall be computed under Treasury Regulation Section 1.1275-4(c)(4) (the "Earnout Interest Portion"). With respect to each ------------------------ Earnout Payment, (i) the Earnout Interest Portion shall be payable in cash, (ii) fifty percent (50%) shall be payable in Itron Common Shares (the "Earnout Stock ------------- Portion") and (iii) the remainder shall be payable in cash (amounts payable - ------- pursuant to clauses (i) and (iii) above are hereinafter referred to in the aggregate as the "Earnout Cash Portion"). The amount of Itron Common Shares to -------------------- be paid to GFI as the Earnout Stock Portion on each occasion shall be that number determined by dividing (A) the Earnout Stock Portion, by (B) the average closing price of the Itron Common Shares as publicly reported by Nasdaq as of 4:00 p.m. Eastern Standard Time on the twenty (20) trading days prior to the fifth (5/th/) trading day following the day that Itron delivers to GFI the written calculation of the LineSoft Revenue and the Earnout Payment, if any, pursuant to Section 3.2(a). The Earnout Cash Portion shall be ------------- -18-

paid by Itron by certified check or wire transfer of immediately available funds to an account specified by GFI. The Earnout Stock Portion shall be delivered to GFI in Itron Common Shares, which are the subject of an effective registration statement filed with the SEC (together with any required actions under applicable state and federal securities laws) and listed on the Nasdaq. In the event that any Earnout Payment or any portion thereof is not paid to GFI on or before the date that such payment is required to be made hereunder, then Itron shall pay interest on the unpaid balance (including principal and any accrued interest) at the rate of ten percent (10%) per annum ("Penalty Interest") until ---------------- the entire Earnout Payment and all accrued interest thereon has been paid; provided, that payment of such Penalty Interest shall not relieve Itron's - -------- obligation pursuant to this Agreement to timely make such Earnout Payment to GFI when each such payment becomes due. (e) Payment in Lieu of Earnout Payment. ---------------------------------- (i) At its sole discretion, Itron may, in whole or in part, satisfy and discharge its obligations to GFI pursuant to this Section ------- 3.2 by paying and issuing to GFI cash and Itron Common Shares in equal --- amounts, up to the aggregate value of the Earnout, which payment shall be applied first against the next applicable Earnout Payment to become due to GFI hereunder. For purposes of this Section 3.2(e), the ------------- aggregate value of the Earnout shall be equal to (A) Thirteen Million Five Hundred Thousand Dollars ($13,500,000), less any amount already paid by Itron to GFI pursuant to this Section 3.2 (excluding any amount ----------- of interest paid in accordance with Sections 3.2(b) or 3.2(c)) (the -------------- ----- "Earnout Prepayment Amount"). The aggregate amount of Itron Common ------------------------- Shares to be paid to GFI pursuant to the foregoing on the occasion of such prepayment shall be that number determined by dividing (A) fifty percent (50%) of the Earnout Prepayment Amount, by (B) the average closing price of the Itron Common Shares as publicly reported by Nasdaq as of 4:00 p.m. Eastern Standard Time on the twenty (20) trading days prior to the fifth (5th) trading day following the day that Itron provides notice to GFI of its intention to make such prepayment hereunder. (ii) If, at any time following the Effective Time of the Merger and prior to the end of the third Earnout Period, either of the following events occurs: (i) as a result of any merger, investment, strategic or commercial alliance, or other event or series of events, Itron or one or more of its Affiliates holds or obtains a controlling ownership interest in an entity that continues to sell (after its acquisition by Itron) a product(s) or acquires assets that constitute a product(s) or enable Itron to market a product(s) that is(are) deployed in the T&D Power Line Design and Engineering Market that: (a) materially competes commercially with the LineSoft Product Line or (b) terminates or discontinues a material element of the LineSoft Product Line; or (ii) any re-assignment, sale, license, lease or other disposition by Itron of a material amount of the assets designated by Itron for the use of the LineSoft Product Line in a manner that is materially detrimental to the commercial sale of the LineSoft Product Line, then, each of the 2002 Threshold, 2003 Threshold and 2004 Threshold shall be reduced by an amount equal to the amount of projected revenue related to the applicable elements of the LineSoft Product Line so affected, including, but not limited to, licenses, software services, maintenance, engineering services and joint-revenue, each as listed on Exhibit E attached ---------- -19-

hereto; provided, that such termination, discontinuance or disposition -------- is not the direct result of a breach of a representation, warranty or covenant in this Agreement by the Company. Notwithstanding the foregoing, if Itron sells, licenses, leases or otherwise disposes of all or substantially all of the LineSoft Product Line (in one or a series of transactions), then Itron shall pay to GFI, in lieu of all other payments under Section 3.2 of this Agreement, the lesser of (i) ----------- the Earnout Prepayment Amount or (ii) (A) Five Million Dollars ($5,000,000) if such disposition occurs in calendar year 2002, (B) Three Million Dollars ($3,000,000) if such disposition occurs in calendar year 2003, and (C) Two Million Dollars ($2,000,000) if such disposition occurs in calendar year 2004. (f) Non-Transferability of Right to Receive Earnout Payments from ------------------------------------------------------------- Itron; No Ownership or Voting Rights. The right of GFI to receive the Earnout - ------------------------------------ Payments pursuant to this Agreement shall in no way, in and of itself, entitle GFI to any ownership interest or voting rights in the surviving corporation or Itron solely on the basis of such right, and in no event shall GFI have the right to transfer its right to receive the Earnout Payments directly from Itron. SECTION 3.3. Exchange of Certificates. ------------------------ (a) Exchange Agent. Prior to the Effective Time of the Merger, Itron -------------- shall engage Chase Mellon to act as exchange agent (the "Exchange Agent") for -------------- the issuance of the Merger Consideration upon surrender of the Certificates. (b) Payment of Merger Consideration. ------------------------------- (i) As of the Effective Time of the Merger, Itron shall have delivered to the Exchange Agent the Initial Merger Consideration consisting of the certificates for the Itron Common Shares comprising the Itron Stock Portion and the Cash Portion to be issued and paid upon the conversion of the Company Shares, as applicable, pursuant to Section 3.1(b) and Exhibit D, and any cash necessary to make payments ------------- --------- in lieu of fractional shares pursuant to Section 3.1(c). At the ------------- Effective Time of the Merger, Itron shall cause the Exchange Agent, pursuant to irrevocable instructions delivered to the Exchange Agent prior thereto, to deliver the Itron Stock Portion, as applicable, the Cash Portion and cash for fractional shares contemplated to be issued and paid pursuant to Section 3.1(c) out of the amounts earlier ------------- delivered by Itron to the Exchange Agent. The Exchange Agent shall not use such funds for any purpose other than as set forth in this Section ------- 3.3(b)(i). -------- (ii) On the date that any Earnout Payment becomes due, Itron shall issue and pay to GFI the applicable Earnout Payment consisting of the certificates for the Itron Common Shares comprising the Earnout Stock Portion, the Earnout Cash Portion and any cash necessary to make payments in lieu of fractional shares pursuant to Section 3.1(c).

of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the certificates representing the Itron Stock Portion, if any, and cash in payment of the Initial Merger Consideration. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the applicable amount of the Initial Merger Consideration, pursuant to Exhibit D, --------- consisting of (i) (with respect to the Company Shareholders who are Accredited Investors) a certificate or certificates representing the number of whole shares of Itron Common Shares, pursuant to Exhibit D, and (with respect to all Company --------- Shareholders) cash into which the Company Shares theretofore represented by such Certificate shall have been converted pursuant to Section 3.1(b), and (ii) (with ------------- respect to the Company Shareholders who are Accredited Investors) any cash payable in lieu of a fractional share of Itron Common Shares, and the Certificate so surrendered shall forthwith be canceled. In addition, GFI shall be entitled to receive in exchange therefor the Earnout Payments, as such Earnout Payments become payable, if at all, under this Agreement. If the shares of Itron Common Shares are to be issued to a Person other than the Person in whose name the Certificate so surrendered is registered, it shall be a condition of exchange that such Certificate shall be properly endorsed or otherwise in proper form for transfer and that the Person requesting such exchange shall pay any transfer or other taxes required by reason of the exchange to a Person other than the registered holder of such Certificate or establish to the reasonable satisfaction of Itron that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 3.3(c), each Certificate shall be ------------- deemed at any time after the Effective Time of the Merger, other than Certificates representing Company Shares for which dissenters' rights are perfected, or that are cancelled as provided in Section 3.1(a), to represent ------------- only the right to receive, upon surrender of such Certificate in accordance with this Section 3.3(c), the applicable amount of the Initial Merger Consideration, ------------- pursuant to Exhibit D, consisting of, as applicable, the number of shares of --------- Itron Common Shares, if any, the Cash Portion, additional cash, if any, in lieu of a fractional share of the Itron Common Shares, and a right, as to Certificates held by GFI, to receive the Earnout Payments, if any, from time to time as provided hereunder, into which the Company Shares theretofore represented by such Certificate shall have been converted pursuant to Sections -------- 3.1 and 3.2. The Exchange Agent shall not be entitled to vote or exercise any - --- --- rights of ownership with respect to the Itron Common Shares held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect thereto for the account of Persons entitled thereto. (d) Distributions with Respect to Unexchanged Company Shares. No dividends -------------------------------------------------------- or other distributions declared or made after the Effective Time of the Merger with respect to the Itron Common Shares with a record date after the Effective Time of the Merger shall be paid to the holder of any unsurrendered Certificate with respect to the Itron Common Shares issuable upon exchange of such Certificates pursuant to this Agreement, and no cash payment (including any cash payment in lieu of fractional shares) shall be paid to any such holder pursuant to Section 3.1 until the holder of record of such Certificate shall surrender ----------- such Certificate in accordance with Section 3.3(c). Subject to the effect of -------------- applicable laws, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing the Itron Common Shares issued in exchange therefor, without interest, (i) at the time of such -21-

surrender, the amount of cash payable pursuant to Section 3.1(b) and any -------------- additional cash payable in lieu of a fractional share of Itron Common Shares to which such holder is entitled pursuant to Section 3.1(b) and the amount of -------------- dividends or other distributions with a record date after the Effective Time of the Merger theretofore paid with respect to such Itron Common Shares, as the case may be, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time of the Merger but prior to surrender and a payment date subsequent to surrender payable with respect to such Itron Common Shares. (e) No Further Ownership Rights in Company Shares. All shares of Itron --------------------------------------------- Common Shares issued and all cash paid as the Initial Merger Consideration upon the surrender of Certificates and all Earnout Payments, if any, issued and paid during or, on a timely basis, following the Earnout Period in accordance with the terms of this Article III, together with any dividends payable on any Itron ----------- Common Shares to the extent contemplated by this Section 3.3, shall be deemed to ----------- have been exchanged and paid in full satisfaction of all rights pertaining to the Company Shares theretofore represented by such Certificates and there shall be no further registration of transfers on the stock transfer books of the Interim Surviving Corporation of the Company Shares represented by such Certificates that were outstanding immediately prior to the Effective Time of the Merger. If, after the Effective Time of the Merger, Certificates are presented to the Interim Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article III, except as otherwise ----------- provided by applicable law. (f) Lost, Stolen or Destroyed Certificates. In the event any Certificate -------------------------------------- shall have been lost, stolen or destroyed, upon the making of an affidavit setting forth that fact by the Person claiming such loss, theft or destruction and, the granting of a reasonable indemnity against any claim that may be made against Itron or the Exchange Agent with respect to such Certificate, Itron shall cause the Exchange Agent to issue to such Person the applicable amount of the Merger Consideration with respect to such lost, stolen or destroyed Certificate to which the holder thereof may be entitled pursuant to this Article ------- III. - --- SECTION 3.4. Stock Transfer Books. At the Effective Time of the Merger, the -------------------- transfer books of the Company with respect to all shares of capital stock or other securities of the Company shall be closed and no further registration of transfers of such shares of capital stock or other securities shall thereafter be made on the records of the Company. SECTION 3.5. Certain Adjustments. If between the date hereof and the Effective ------------------- Time of the Merger or, in the case of the Earnout Payment, between the date that Itron delivers a written calculation of the LineSoft Revenue and the Earnout Payment and the date that the Earnout Stock Portion is actually paid to GFI, the outstanding shares of the Company Common Stock or Itron Common Shares shall be changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination or exchange of shares, or any dividend payable in stock or other securities shall be declared thereon with a record date within such period, the Conversion Number and the Merger Consideration shall be adjusted accordingly to provide the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, split-up, combination, exchange or dividend. -22-

SECTION 3.6. Reorganization. -------------- (a) Subject to the last proviso in Section 3.6(b) below, the Merger and -------------- the Step Two Merger, together, are intended to qualify as a "reorganization" as described in Section 368 of the Code, and this Agreement is intended to constitute a "plan of reorganization" within the meaning of the regulations promulgated under Section 368 of the Code. (b) Except as otherwise required by a Governmental Entity pursuant to a determination (as defined in Section 1313 of the Code) or otherwise, or by applicable law, neither party shall (i) take a position on any tax returns or take any other action inconsistent with the treatment of the Merger for tax purposes as a reorganization within the meaning of Section 368(a)(1)(A) of the Code, or (ii) take any action or fail to take any action, which action or failure is reasonably likely to cause any of the representations or agreements set forth in such party's certificate to be executed and substantially in the form of Exhibit 10.6 to be untrue,; provided, however, that if the closing price ------------ of a share of Itron Common Shares as reported by Nasdaq at 4:00 p.m. Eastern Standard Time on the Closing Date is less than $15.50, then this Section 3.6 ----------- shall be of no further force or effect.

(vi) For purposes of this Section 10.3, a Company Shareholder who is ------------ an indemnifying party hereunder shall be deemed to have received notice for purposes of this Article X, once the Shareholders' Representatives have all --------- received a Claim Notice or Payment Certificate, as applicable. (b) Resolution of Claims. -------------------- (i) All claims for indemnification under this Agreement, other than Third Party Claims as described in Section 10.4, shall be submitted to ------------ final and binding arbitration in Spokane, Washington, which arbitration shall, except as specifically stated herein, be conducted in accordance with the CPR Non-Administered Arbitration Rules (the "CPR Rules") then in --------- effect; provided, however, that the parties agree first to try in good -------- ------- faith to resolve any claim for indemnification that does not exceed Five Hundred Thousand Dollars ($500,000) by mediation under the CPR Mediation Procedure for Business Disputes, before resorting to arbitration; provided, -------- further, that, in the event of an arbitration, the arbitration provisions ------- of this Agreement shall govern over any conflicting rules which may now or hereafter be contained in the CPR Rules. (ii) The final decision of the arbitrator(s) shall be a reasoned opinion based on applicable law and furnished in writing to the parties and will constitute a conclusive determination of the issue in question, binding upon the parties. The arbitrator(s) shall have the authority to grant any equitable and legal remedies that would be available in any judicial proceeding instituted to resolve a claim for indemnification. Any judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction over the subject matter thereof. (iii) Any such arbitration shall be conducted before a single arbitrator, who will be compensated for his or her services, as provided below in Section 10.3(b)(v), at a rate to be determined by the parties or ------------------ pursuant to the CPR Rules, but based upon -62-

reasonable hourly or daily consulting rates for the arbitrator in the event the parties are not able to agree upon his or her rate of compensation. (iv) The parties shall select the arbitrator by mutual agreement promptly following initiation of arbitration in accordance with the CPR Rules; provided, however, that in the event the parties are unable to reach -------- ------- such agreement within twenty (20) days of initiation, the CPR shall have the authority to select an arbitrator from a list of arbitrators who are partners in a nationally recognized firm of independent certified public accountants from the management advisory services department (or comparable department or group) of such firm or who are partners in a major law firm; provided, however, that such accounting firm or law firm cannot be a firm -------- ------- that has within the last three (3) years rendered, or is then rendering, services to any party hereto or, in the case of a law firm, appeared, or is then appearing, as counsel of record in opposition to any party hereto. Any arbitrator selected to serve shall be qualified by training and experience for the matters for which such arbitrator is designated to serve. If the parties are unable to agree upon one arbitrator, each shall appoint an arbitrator and these appointees shall appoint a third arbitrator, in which case the arbitration determination shall be made by a majority decision of the three selected arbitrators. (v) The prevailing party in any arbitration shall be entitled to an award of attorneys' fees and costs, and all costs of arbitration, including those provided for above, will be paid by the losing party, subject in each case to a determination by the arbitrator as to which party is the prevailing party and the amount of such fees and costs to be allocated to such party. Any amounts payable under this subsection will be reimbursed as if the amount of such awarded fees and costs were not contested, and the parties will have no further liability for any amounts payable under this Section 10.3(b) for such fees and costs. --------------- (vi) The arbitrator(s) chosen in accordance with these provisions shall not have the power to alter, amend or otherwise affect the terms of these arbitration provisions or the provisions of this Agreement or any other documents that are executed in connection therewith. SECTION 10.4. Third Party Claims. ------------------ (a) If an indemnified party receives notice of a demand for arbitration, summons or other notice of the commencement of a proceeding, audit, investigation, review, suit or other action by a third party (any such action a "Third Party Claim") for which it intends to seek indemnification hereunder, it ----------------- shall give the indemnifying party prompt written notice of such claim (together with all copies of the claim, any process served, and all filings with respect thereto), so that the indemnifying party's defense of such claim under this Section 10.4 may be timely instituted. The indemnifying party under this Article - ------------ ------- X shall have the right to conduct and control, through counsel (reasonably - - acceptable to the indemnified party) of its own choosing and at its own cost, any Third Party Claim, compromise, or settlement thereof. Assumption by an indemnifying party of control of any such defense, compromise, or settlement shall not be a waiver by it of its right to challenge its obligation to indemnify the indemnified -63-

party. The indemnified party may, at its election, participate in the defense of any such claim, action, or suit through counsel of its choosing, but the fees and expenses of such counsel shall be at the expense of the indemnified party, unless the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from or in addition to those available to the indemnifying party (in which case, if the indemnified party notifies the indemnifying party in writing that it elects separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party with respect to such defenses). (b) If the indemnifying party fails to defend diligently any Third Party Claim, then the indemnified party may defend, with counsel of its own choosing, and (i) settle such Third Party Claim and then recover from the indemnifying party the amount of such settlement or of any judgment and the reasonable costs and expenses of such defense, or (ii) litigate the Third Party Claim to the completion of trial or arbitration and then promptly recover from the indemnifying party the reasonable costs and expense of such defense and the amount of the judgment, verdict or award, if any, against the indemnified party. (c) Notwithstanding Section 10.4(b)(i), the indemnifying party shall not ------------------ be liable to pay or otherwise satisfy any settlement of a Third Party Claim unless the indemnified party shall have given the indemnifying party written notice of the terms of the proposed settlement at least twenty (20) days prior to entering into such settlement. (d) Without the consent of the indemnified party, the indemnifying party shall not compromise or settle any Third Party Claim if such settlement involves an admission of liability or wrongdoing on the party of the indemnified party, or a restriction on the operation of the indemnified party's business in the future or would adversely affect the business reputation or Tax liability of the indemnified party. No Third Party Claim may be settled by an indemnifying party without the written consent of the indemnified party, which consent shall not be unreasonably withheld or delayed. No settlement of a Third Party Claim that involves the payment of money only shall be made by any indemnifying party unless the indemnifying party has and reserves a sufficient amount of immediately available funds to provide for such settlement. (e) Itron, the Shareholders Representatives, and the Interim Surviving Corporation shall cooperate in all reasonable respects with each other in connection with the defense, negotiation, or settlement of any legal proceeding, claim, or demand referred to in this Section 10.4. ------------ SECTION 10.5. Time Limit. The provisions of this Article X (other than the last ---------- --------- sentence of Section 10.6(a)) shall apply only to Losses that are incurred or ---------------- relate to claims, demands, or liabilities that are asserted or threatened before the expiration of the earlier of: (x) the period thirty (30) days after completion in calendar year 2003 of the Itron 2002 calendar year audit and (y) April 30, 2003; provided, however, that: (i) the obligation of either party to -------- ------- indemnify the other and its directors and officers for such claims for which a Claim Notice is given within the time period set forth above shall continue until the final resolution of each such claim; (ii) the limitation set forth in this Section 10.5 shall not apply to any right to indemnification for a failure ------------ -64-

to perform any agreement or covenant set forth in this Agreement or for any of the representations set forth in Sections 4.1(a), 4.1(b) 4.1(c)(i), 4.2(a), --------------- ------ --------- ------ 4.2(b) and 4.2(c)(i), which shall survive the Effective Time of the Merger - ------ --------- indefinitely; and (iii) the representations set forth in Section 4.1(j) shall -------------- survive until the expiration of the applicable statute of limitations. Furthermore, the right to indemnification for Taxes under Section 10.1(c) hereof --------------- shall survive until the expiration of the applicable statute of limitation for such Taxes. SECTION 10.6. Limitations. ----------- (a) The aggregate amount for which the Company Shareholders shall be liable pursuant to this Article X shall not exceed Three Million Dollars --------- ($3,000,000); provided, however, that the limitation set forth in this Section -------- ------- ------- 10.6 shall not apply to any right to indemnification under Section 10.1(c) or - ---- any right to indemnification for any breach or claim of breach of the representations and warranties contained Sections 4.1(a), 4.1(b), or 4.1(c)(i). --------------- ------ --------- In addition, the liability of each Company Shareholder shall not exceed such Company Shareholder's proportionate share of the Three Million Dollars ($3,000,000) as set forth on Schedule 10.6. Except for Losses based upon fraud ------------- or knowing misrepresentation, the sole remedy of Itron for breaches of this Agreement shall be claims made in accordance with and subject to the limitations in this Article X. --------- (b) The indemnification obligations of the Company Shareholders under this Article X shall be satisfied: (i) by payment to Itron of a proportionate amount - --------- of the obligations by all Company Shareholders other than GFI from the Escrow and (ii) by payment of a proportionate amount of the obligations from GFI. Such proportionate amounts are as set forth on Schedule 10.6. The aggregate value of ------------- claims paid by means of the payments to Itron pursuant to this Article X shall --------- be deemed to reduce the total Merger Consideration otherwise payable to the Company Shareholders pursuant to Section 3.1. ----------- SECTION 10.7. Shareholders' Representatives. ----------------------------- (a) Johnny Humphreys, Fred A. Brown and GFI shall be constituted and appointed as agents (the "Shareholders' Representatives") for and on behalf of ----------------------------- the Company Shareholders, their respective Affiliates and their respective representatives to give and receive notices and communications, to organize or assume the defense of third-party claims, to agree to, negotiate or enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to third-party claims, and to take all actions necessary or appropriate in the judgment of the Shareholders' Representatives for the accomplishment of the foregoing. Unless and until GFI designates any other individual to serve as its designee, all communications with GFI in its Shareholders' Representative capacity shall be addressed to the attention of Andrew Osler. Such agency may be changed by the holders of at least seventy-five percent (75%) of the Company Common Stock at the Effective Time of the Merger upon not less than ten (10) days' prior written notice to Itron. No bond shall be required of the Shareholders' Representatives, and the Shareholders' Representatives shall receive no compensation for services rendered; provided, however, that they shall be entitled to reimbursement of their expenses in serving as Shareholders' Representatives. Notices or communications to or from the Shareholders' Representatives shall constitute notice to or from -65-

the Company Shareholders. Notwithstanding the foregoing, nothing in this Section ------- 10.7 shall be construed to alter the authority of GFI with respect to its rights - ---- under Section 3.2. ----------- (b) The Shareholders' Representatives shall not be liable to any of the Company Shareholders for any act done or omitted hereunder as Shareholders' Representatives except to the extent they individually or collectively acted with gross negligence or willful misconduct, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence that the Shareholders' Representatives did not act with gross negligence or willful misconduct. The Company Shareholders shall severally and proportionately indemnify the Shareholders' Representatives and hold them harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Shareholders' Representatives and arising out of or in connection with the acceptance or administration of the duties hereunder. (c) The Shareholders' Representatives shall have reasonable access to information about the former Company business and operations and the reasonable assistance of Itron's officers and employees for purposes of performing their duties and exercising their rights hereunder; provided, that the Shareholders' -------- Representatives shall treat confidentially and not disclose any nonpublic information from or about Itron to anyone (except on a need to know basis to individuals who agree to treat such information confidentially). The Shareholders' Representatives shall be third party beneficiaries of the terms of this Section 10.7(c). --------------- SECTION 10.8. Actions of the Shareholders' Representatives. A unanimous -------------------------------------------- decision, act, consent or instruction of the Shareholders' Representatives shall constitute a decision of all Company Shareholders and shall be final, binding and conclusive upon each such Company Shareholders and Itron may rely upon any written decision, act, consent or instruction of the Shareholders' Representatives as being the decision, act, consent or instruction of the Company Shareholders. Itron is hereby relieved from any liability to any Person for any acts done by them in accordance with such written decision, act, consent or instruction of the Shareholders' Representatives. ARTICLE XI GENERAL PROVISIONS SECTION 11.1. Survival of Representations and Warranties. The representations ------------------------------------------ and warranties made by the parties to this Agreement and contained herein or in any instrument delivered by the Company or Itron pursuant to this Agreement shall survive until the expiration of the earlier of: (x) the period thirty (30) days after completion in calendar year 2003 of the Itron 2002 calendar year audit and (y) April 30, 2003; provided, that, the representations and warranties -------- contained in Section 4.1(j) shall survive until the relevant expiration of the -------------- statute of limitations period and Sections 4.1(a), 4.1(b), 4.1(c)(i), 4.2(a), --------------- ------ --------- ------ 4.2(b) and 4.2(c)(i) shall survive indefinitely. - ------ --------- SECTION 11.2.

Exhibit 4.1 SUPPORT AGREEMENT - FRED A. BROWN SUPPORT AGREEMENT, dated as of February 14, 2002 (the "Support Agreement"), by and between Itron, Inc. ("Itron") and Fred A. Brown (the "Shareholder"). RECITALS A. Itron, LS Combination, Inc. ("Merger Sub") and LineSoft Corporation (the "Company") are entering into an Agreement and Plan of Reorganization of even date herewith in the form attached hereto as Exhibit A (the "Merger Agreement") which provides (subject to the conditions set forth therein) for the merger of the Merger Sub with and into the Company (the "Merger"). B. The Shareholder has received and reviewed a copy of the Merger Agreement. C. The Shareholder owns the shares of Company Common Stock (the "Common Stock") as identified on Annex I hereto (such shares, together with all shares of Common Stock of the Company, if any, subsequently acquired by the Shareholder during the term of this Support Agreement, being referred to as the "Shares"). D. Itron would not enter into the Merger Agreement without the Shareholder's execution and delivery of this Support Agreement. E. In order to induce Itron to enter into the Merger Agreement, the Shareholder has agreed to enter into and perform the Shareholder's obligations under this Support Agreement. NOW, THEREFORE, in consideration of the agreements and covenants contained herein, the Shareholder and Itron agree as follows: AGREEMENT Capitalized terms not otherwise defined herein shall have the meanings assigned to them in the Merger Agreement. 1. Irrevocable Proxy; Agreement to Vote Shares The Shareholder shall execute an irrevocable written proxy in substantially the form of ExhibitB with respect to the Shares, and shall, if requested by Itron, vote or cause such Shares to be voted (a) in favor of adoption and approval of the Merger Agreement (as in effect on the date hereof) and all transactions relating thereto or contemplated thereby at every meeting of the shareholders of the Company at which such matters are considered and at every adjournment thereof and in connection with every proposal to take action by written consent with respect thereto, and (b) against any proposal by a party other than Itron to merge or consolidate with the Company or any subsidiary of the Company or to sell all or substantially all the assets of or any sales of equity interest in the Company or any subsidiary of the Company at every meeting of the shareholders of the Company at which such matters are considered and at every adjournment

thereof and in connection with every proposal to take action by written consent with respect thereto. The Shareholder also agrees, if requested by Itron, to vote or cause such Shares to be voted in favor of any payment to be made by the Company or Itron to a "disqualified person" (as defined in Section 280G of the Internal Revenue Code) with respect to the Company in accordance with the shareholder approval requirements of Section 280G of the Internal Revenue Code. 2. No Voting Trusts The Shareholder agrees that the Shareholder will not, nor will the Shareholder permit any entity under the Shareholder's control to, deposit any Shares in a voting trust or subject the Shares to any agreement, arrangement or understanding with respect to the voting of the Shares inconsistent with this Support Agreement. 3. Limitation on Sales During the term of this Support Agreement, the Shareholder agrees not to sell, assign, transfer, pledge, encumber or otherwise dispose of any of the Shares except to Itron. 4. Waiver of Dissenters' Rights The Shareholder hereby irrevocably and unconditionally waives, and agrees to cause to be waived and to prevent the exercise of, any rights of appraisal, any dissenters' rights and any similar rights relating to the Merger that the Shareholder may have by virtue of the ownership of any outstanding Shares. 5. Letter of Transmittal As soon as practicable following the Effective Time of the Merger, the Shareholder shall execute and deliver a letter of transmittal as contemplated under Section 3.3(c) of the Merger Agreement. 6. Restrictions on Sale of Itron Common Stock The Shareholder, by signing in the space provided below, agrees that for a period of [one year] following the Effective Time of the Merger, the Shareholder will not in any 30-day period sell, contract to sell, transfer or otherwise dispose of more than fifty percent (50%) of the Itron Common Stock received by the Shareholder in connection with the consummation of the Merger. 7. Indemnification of Itron The Shareholder, by signing in the space provided below, agrees to be bound (subject to the consummation of the Merger) to pay, on a several (and not joint) basis, the Shareholder's pro rata portion (as specified in Section 10.6(a) of the Merger Agreement) of the Company Shareholders' indemnification obligations in accordance with Article [X] of the Merger Agreement, as if the Shareholder were a party thereto, and acknowledges that such provisions -2-

call for the Shareholder as well as other Company Shareholders to indemnify Itron in accordance with the Merger Agreement, subject to the limitations thereof. 8. Tax Matters 8.1 The Shareholder shall timely pay, and shall indemnify and hold each of Itron and Merger Sub harmless from and against, all transfer, documentary, sales, use, stamp, registration and similar taxes, and the Shareholder's own income taxes, on the transfer of Shares contemplated by the Merger Agreement, to the extent they relate specifically to the issuance of shares of Itron Common Stock to Shareholder, and Shareholder shall, at Shareholder's own expense, file all necessary tax returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, income registration, and similar taxes. 8.2 Except as otherwise required by a Governmental Entity pursuant to a determination (as defined in Section 1313 of the Code) or otherwise, or by applicable law, the Shareholder shall not take a position on any tax returns or take any other action inconsistent with the treatment of the Merger for tax purposes as a reorganization within the meaning of Section 368(a)(1)(A) of the Code; provided, however, that if the closing price of a share of Itron Common Stock as reported by Nasdaq at 4:00 p.m. Eastern Standard Time on the Closing Date is less than $15.50, then this Section 9.2 shall be of no further force or effect. Notwithstanding anything to the contrary herein, neither Itron nor Merger Sub makes any representation or warranty with respect to any tax consequences to the Company or the Shareholder under this Agreement, the Merger Agreement or as a result of the Merger, except as otherwise set forth in the Merger Agreement. 9. Representations and Warranties of Shareholder The Shareholder represents and warrants to Itron as follows: 9.1 Authority; No Approvals; No Conflicts; No Liens The Shareholder has the necessary power or capacity (as the case may be) and authority to execute this Support Agreement, to make the representations, warranties and covenants herein and to perform the obligations hereunder. This Support Agreement is duly executed and is a legal, valid and binding obligation of the Shareholder, enforceable in accordance with its terms. The execution, delivery and performance of this Support Agreement by the Shareholder will not (a) constitute a violation (with or without the giving of notice or lapse of time or both) of any provision of any law applicable to the Shareholder, (b) require any consent, approval or authorization of, or notice to, any person, corporation, partnership, domestic or foreign governmental authority or other organization or entity, (c) result in a default under, an acceleration or termination of, or the creation in any party of the right to accelerate, terminate, modify or cancel, any material agreement, lease, note or other restriction, encumbrance, obligation or liability to which the Shareholder is a party or by which the Shareholder is bound or (d) result in the creation or imposition of any lien on any of the Shares of Company Common Stock held by the Shareholder. -3-

9.2 Ownership of Shares Annex I hereto correctly sets forth, as of the date of this Support Agreement, the number of shares of Common Stock owned beneficially and of record by the Shareholder. The Shareholder owns beneficially and of record the Shares set forth on Annex I free and clear of any lien, encumbrance, preemptive right, right of first offer or refusal, or other prior claim, and delivery of the certificates representing the Shares by the Shareholder to the Exchange Agent at the Effective Time of the Merger, pursuant to the terms of the Merger Agreement will be sufficient to allow the Shares to be cancelled, free and clear of any lien, encumbrance, preemptive right, right of first offer or refusal, or other prior claim. 9.3 Sophistication; Accreditation The Shareholder, either alone or with the assistance of Shareholder's professional advisor, is a sophisticated investor, able to fend for Shareholder's interests in the transactions contemplated by the Operative Documents, and has such knowledge and experience in financial and business matters that Shareholder is capable of evaluating the merits and risks of the prospective investment in Itron Common Stock. The Itron Common Stock being acquired by the Shareholder in the Merger is for investment for Shareholder's respective account, not as a nominee or agent; the undersigned has no present intention of selling, granting any participation in or otherwise distributing any of the Itron Common Stock in a manner contrary to the Securities Act or to any applicable state securities or Blue Sky law, nor does the undersigned have any contract, undertaking, agreement or arrangement with any person or entity to sell, transfer or grant a participation to such person or entity with respect to any of the Itron Common Stock to be received in the Merger. 9.4 Claims Against the Company The Shareholder does not have any past, present or contemplated claims against the Company or any of its officers and directors. Shareholder and the Company shall continue to be parties to the agreements and instruments identified in Section 19.1 of this Agreement until terminated as provided in Section 19.1. 9.5 Residency The Shareholder is a resident of the state as set forth on Annex I. 9.6 Accuracy of Representations The representations and warranties contained in this Support Agreement are accurate in all respects as of the date of this Support Agreement and will be accurate in all respects at all times through the Effective Time of the Merger. -4-

10. Specific Performance The Shareholder acknowledges that in the event of any breach of this Support Agreement by the Shareholder, Itron would be irreparably harmed, no adequate remedy at law or in damages would exist and damages would be difficult to determine. Accordingly, the Shareholder agrees that injunctive relief or other equitable remedy, in addition to all remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that Itron has an adequate remedy at law. The Shareholder agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with the seeking or obtaining of such equitable relief by Itron. 11. Attorneys' Fees If any action at law or in equity is necessary to enforce or interpret the terms of this Support Agreement, the prevailing party will be entitled to reasonable attorneys' fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled. 12. Non-Exclusivity The rights and remedies of Itron under this Support Agreement are not exclusive of or limited by any other rights or remedies which it may have, whether at law, in equity, by contract or otherwise, all of which shall be cumulative (and not alternative). 13. Term of Support Agreement; Termination The term of this Support Agreement shall commence on the date hereof and terminate upon (a) the date on which the Merger Agreement is terminated in accordance with its terms, or (b) the latest to occur of (i) the date on which the determination of the final Earnout Payment, if any, becomes conclusive and binding, (ii) the date on which the final Earnout Payment, if any, has been paid, (iii) the date on which each required payment related to, or in lieu of, each Earnout Payment, if any, has been paid, (iv) the date on which Itron has fully satisfied its registration obligations specified in Section 6.1(c) of the Merger Agreement in connection with Itron Common Shares issued as part of an Earnout Payment and/or Earnout Payment Amount, and (v) the expiration of the survival and indemnification periods applicable to the Shareholder and Itron as specified in the Merger Agreement. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, such termination shall not relieve any party from liability for any breach of this Support Agreement prior to such termination. 14. Entire Support Agreement This Support Agreement and the Merger Agreement constitute the entire agreement between the parties with respect to the subject matter hereof and thereof and supersedes all prior agreements and understandings between the parties with respect thereto. -5-

Tax Matters 9.1 The Shareholder shall timely pay, and shall indemnify and hold each of Itron and Merger Sub harmless from and against, all transfer, documentary, sales, use, stamp, registration and similar taxes, and the Shareholder's own income taxes, on the transfer of Shares contemplated by the Merger Agreement, to the extent they relate specifically to the issuance of shares of Itron Common Stock to Shareholder, and Shareholder shall, at Shareholder's own expense, file all necessary tax returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, income, registration, and similar taxes. 9.2 Except as otherwise required by a Governmental Entity pursuant to a determination (as defined in Section 1313 of the Code) or otherwise, or by applicable law, the Shareholder shall not take a position on any tax returns or take any other action inconsistent with the treatment of the Merger for tax purposes as a reorganization within the meaning of Section 368(a)(1)(A) of the Code; provided, however, that if the closing price of a share of Itron Common Stock as reported by Nasdaq at 4:00 p.m. Eastern Standard Time on the Closing Date is less than $15.50, then this Section 9.2 shall be of no further force or effect. Notwithstanding anything to the contrary herein, neither Itron nor Merger Sub makes any representation or warranty with respect to any tax consequences to the Company or the Shareholder under this Agreement, the Merger Agreement or as a result of the Merger, except as otherwise set forth in the Merger Agreement. 10.

This Support Agreement is duly executed and is a legal, valid and binding obligation of the Shareholder, enforceable in accordance with its terms. The execution, delivery and performance of this Support Agreement by the Shareholder will not (a) constitute a violation (with or without the giving of notice or lapse of time or both) of any provision of any law applicable to the Shareholder, (b) require any consent, approval or authorization of, or notice to, any person, corporation, partnership, domestic or foreign governmental authority or other organization or entity, (c) result in a default under, an acceleration or termination of, or the creation in any party of the right to accelerate, terminate, modify or cancel, any material agreement, lease, note or other restriction, encumbrance, obligation or liability to which the Shareholder is a party or by which the Shareholder is bound or (d) result in the creation or imposition of any lien on any of the Shares of Company Common Stock held by the Shareholder. -3-

10.2 Ownership of Shares Annex I hereto correctly sets forth, as of the date of this Support Agreement, the number of shares of Common Stock owned beneficially and of record by the Shareholder. The Shareholder owns beneficially and of record the Shares set forth on Annex I free and clear of any lien, encumbrance, preemptive right, right of first offer or refusal, or other prior claim, and delivery of the certificates representing the Shares by the Shareholder to the Exchange Agent at the Effective Time of the Merger, pursuant to the terms of the Merger Agreement will be sufficient to allow the Shares to be cancelled, free and clear of any lien, encumbrance, preemptive right, right of first offer or refusal, or other prior claim. 10.3 Sophistication; Accreditation The Shareholder, either alone or with the assistance of Shareholder's professional advisor, is a sophisticated investor, able to fend for Shareholder's interests in the transactions contemplated by the Operative Documents, and has such knowledge and experience in financial and business matters that Shareholder is capable of evaluating the merits and risks of the prospective investment in Itron Common Stock. The Itron Common Stock being acquired by the Shareholder in the Merger is for investment for Shareholder's respective account, not as a nominee or agent; the undersigned has no present intention of selling, granting any participation in or otherwise distributing any of the Itron Common Stock in a manner contrary to the Securities Act or to any applicable state securities or Blue Sky law, nor does the undersigned have any contract, undertaking, agreement or arrangement with any person or entity to sell, transfer or grant a participation to such person or entity with respect to any of the Itron Common Stock to be received in the Merger. 10.4 Claims Against the Company The Shareholder does not have any past, present or contemplated claims against the Company or any of its officers and directors.

Specific Performance The Shareholder acknowledges that in the event of any breach of this Support Agreement by the Shareholder, Itron would be irreparably harmed, no adequate remedy at law or in damages would exist and damages would be difficult to determine. Accordingly, the Shareholder agrees that injunctive -4-

relief or other equitable remedy, in addition to all remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that Itron has an adequate remedy at law. The Shareholder agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with the seeking or obtaining of such equitable relief by Itron. 12. Attorneys' Fees If any action at law or in equity is necessary to enforce or interpret the terms of this Support Agreement, the prevailing party will be entitled to reasonable attorneys' fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled. 13.

Subject to the preceding sentence, this Support Agreement shall be binding upon the Shareholder and Shareholder's heirs, estate, executors, personal representatives, successors and assigns, and shall inure to the benefit of Itron and its successors and assigns.

Exhibit 99.1 [LETTERHEAD OF ITRON, INC.] FOR IMMEDIATE RELEASE ITRON TO ACQUIRE LINESOFT CORPORATION Itron Expands Presence In The Utility Market With The Acquisition Of Software And Engineering Services SPOKANE, WA. -- February 15, 2002 -- Itron, Inc., (NASDAQ:ITRI), a leading technology provider and source of knowledge to the energy and water industries for collecting, analyzing, and applying critical data about electric, gas, and water usage, today announced an agreement to acquire LineSoft Corporation for $42 million in cash and stock. LineSoft is a leading provider of software solutions and engineering consulting services for optimizing utility transmission and distribution systems. "The acquisition of LineSoft is a major step to broaden Itron's mission of helping utilities optimize the delivery and use of energy and water," said LeRoy Nosbaum, Itron CEO. "For some time Itron has talked about moving beyond data collection and information creation for meter reading. LineSoft will give Itron a suite of new products, principally design tools, that can help utilities design new transmission and distribution lines as well as upgrade existing facilities." LineSoft is a privately held company, based in Spokane, Washington, that licenses and sells, primarily to electric utilities, the following: . Software seat licenses and software services for the efficient design, construction and maintenance of transmission and distribution lines and distribution substations, including new construction, upgrades and maintenance, . Engineering design services for transmission and distribution lines, and . Utility pole joint use services, which help utilities keep track of what is attached to existing distribution poles, what can be added to them and whether or not the poles are in compliance with existing codes and safety regulations. "LineSoft is at the right time and the right place with software and services that are critical for helping utilities deal with rapidly increasing economic pressures to optimize assets, people and budgets. Itron's sales channels, marketing and brand position in the utility market will considerably increase the industry's awareness of LineSoft's product and service offering. The combination of Itron's data gathering and communication expertise with LineSoft's transmission and distribution system expertise will result in powerful solutions that give utilities the knowledge they need to more closely match distribution resources with distribution needs." LineSoft President, CEO, and Founder Fred A. Brown agrees that Itron is ideally positioned to broadly serve the utility industry. "Over the years LineSoft customers have embraced our T&D

design solutions and engineering know-how, and I'm proud to say we've consistently exceeded their solution expectations. Bringing these two companies together is a great move for LineSoft and Itron customers and employees." About the Transaction: . The total purchase price is $42 million, subject to additional earnout payments to LineSoft shareholders in the event that revenue hurdles in 2002 to 2004 are significantly exceeded. . Half of the purchase price will be paid in cash and half in Itron common stock at closing. Any earnout payments will also be paid half in cash and half in Itron common stock. . The number of Itron shares to be issued at closing will be based on the average price of Itron stock prior to closing, subject to a minimum and maximum per share price of $22 to $32. . The transaction has been approved by both Itron's and LineSoft's Board of Directors, and is subject to customary closing conditions. . The transaction is expected to close in March 2002. Impact of the Transaction on Itron's Previously Issued Guidance: . Prior to this transaction, Itron projected a revenue range for 2002 of $248 to $260 million, which represents 10-15% growth over 2001, and an EPS range of $.88 to $.95 per diluted share, which represents 20-30% growth over 2001. .
