RECITALS A. The Boards of Directors of each of Parent, Sub, the Company, and Siemens have determined that it is in the best interests of their respective stockholders, and the Board of Directors of Sub and the Company have determined that it is advisable, to effect a statutory merger of Sub and the Company pursuant to this Agreement (the "Merger") and, in furtherance thereof, have approved the Merger upon the terms and subject to the conditions set forth herein. B. Concurrently with the execution and delivery of this Agreement, as a material inducement to Parent and Sub to enter into this Agreement: (i) Siemens and certain stockholders of the Company are entering into Voting Agreements, in substantially the form attached hereto as Exhibit A (the "Voting Agreements"), with Parent; (ii) Siemens is entering into the Stockholder Agreement, in substantially the form attached hereto as Exhibit B (the "Stockholder Agreement"), with Parent; and (iii) each of the Key Employees (as defined herein) is entering into a Non-Competition Agreement, in substantially the form attached hereto as Exhibit C (the "Non-Competition Agreement"), with Parent. C. The Company has entered into an Asset Purchase Agreement with Castle Networks, Inc., dated as of April 29, 2002 (the "Asset Purchase Agreement") and a Stock Purchase Agreement with Siemens Information and Communication Networks, Inc. ("Siemens ICN"), dated as of April 30, 2002 (the "Stock Purchase Agreement" and, together with the Asset Purchase Agreement, the "Voice Transfer Agreements"), pursuant to which on the date hereof the Company transferred its business of designing, manufacturing, marketing, and selling packet voice network equipment for the telecommunications industry (the "Voice Business") to an affiliate of Siemens (such transfer and the transactions contemplated by the Voice Transfer Agreements, as such agreements exist on the date hereof (or as such agreements may be amended with the consent of Parent), being hereinafter referred to as the "Voice Transaction"). NOW, THEREFORE, in consideration of the foregoing and the mutual representations and warranties, covenants and agreements herein contained, the Company, Siemens, Parent and Sub hereby agree as follows: ARTICLE I THE MERGER 1.1 The Merger. At the Effective Time (as defined in Section 1.2 hereof) and subject to and upon the terms and conditions of this Agreement and the applicable provisions of the General Corporation Law of the State of Delaware ("Delaware Law"), Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation of the Merger (the "Surviving Corporation") and as a wholly-owned subsidiary of Parent. 1.2 Effective Time. Unless this Agreement is earlier terminated pursuant to Section 10.1 hereof, the closing of the Merger (the "Closing") will take place as promptly as practicable after satisfaction or waiver of the conditions set forth in Article VII hereof (other than those conditions which, by their terms, are to be satisfied or waived at Closing), at the offices of Shearman & Sterling, 599 Lexington Avenue, New York, New York, unless another time and/or place is mutually agreed upon in writing by the parties hereto. The date upon which the Closing actually occurs shall be referred to herein as the "Closing Date." On the Closing Date, the parties hereto shall cause the Merger to be consummated by filing a Certificate of Merger in substantially the form attached hereto as Exhibit D (the "Certificate of Merger"), with the Secretary of State of the State of Delaware, in accordance with the applicable provisions of Delaware Law (the date and time of such filing, or such other mutually agreed time as may be specified in the Certificate of Merger, shall be referred to herein as the "Effective Time"). 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, except as otherwise agreed to pursuant to the terms of this Agreement, all the property, rights, privileges, powers and franchises of the Company and Sub shall vest in the Surviving Corporation, and all debts, liabilities, obligations, restrictions, disabilities and duties of the Company and Sub shall become the debts, liabilities, obligations, restrictions, disabilities and duties of the Surviving Corporation. 1.4 Certificate of Incorporation and Bylaws. (a) Subject to Section 6.28, unless otherwise determined by Parent prior to the Effective Time, at the Effective Time the certificate of incorporation of Sub, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with Delaware Law and as provided in such certificate of incorporation; provided, however, that at the Effective Time, Article I of the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to read as follows: "The name of the corporation is Unisphere Networks, Inc." (b) Unless otherwise determined by Parent prior to the Effective Time, at the Effective Time, the bylaws of Sub, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with Delaware Law and as provided in the certificate of incorporation of the Surviving Corporation and such bylaws. 1.5 Directors and Officers. (a) Directors. Unless otherwise determined by Parent prior to the Effective Time, the directors of Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold the office of a director of the Surviving Corporation in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective -2- successors are duly elected or appointed and qualified or until their earlier death, resignation or removal. (b) Officers. Unless otherwise determined by Parent prior to the Effective Time, the officers of Sub immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, each to hold office in accordance with the provisions of the bylaws of the Surviving Corporation. 1.6 Effect of Merger on the Capital Stock of the Constituent Corporations. (a) Effect on Company Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Sub, the Company or holders of any of the capital stock of the Company, each outstanding share of Company Common Stock, shall, upon the terms and subject to the conditions set forth in this Agreement, be canceled and extinguished and be converted automatically into the right to receive (x) such number of shares of Parent Common Stock equal to the Stock Exchange Ratio and (y) an amount of cash equal to the Cash Exchange Ratio. The aggregate number of shares of Parent Common Stock to be issued to each Stockholder and the aggregate amount of cash to be paid to each Stockholder under this Section 1.6(a) shall be calculated by aggregating all shares of Company Common Stock held by such Stockholder, so that (i) the aggregate number of shares of Parent Common Stock to be issued to such Stockholder shall be equal to the number of shares of Company Common Stock held by such Stockholder multiplied by the Stock Exchange Ratio (the "Stock Consideration"), with fractional shares treated in the manner set forth in Section 1.8(f) hereof; and (ii) the aggregate amount of cash to be paid to such Stockholder shall be equal to the aggregate number of shares of Company Common Stock held by such Stockholder, multiplied by the Cash Exchange Ratio (the "Cash Consideration," and together with the Stock Consideration, the "Merger Consideration"), rounded to the nearest whole cent, with $0.005 rounded up. (b) Payment of Cash Consideration. At the Closing, Parent shall deliver to Siemens, the aggregate amount of Cash Consideration payable to Siemens under Section 1.6(a) hereto, by wire transfer in immediately available funds to the bank account designated by Siemens at least two (2) business days prior to the Closing Date. (c) Assumption of Company Options; Treatment of Company Warrants. (i) As soon as practicable following the Closing but effective as of the Effective Time, each Company Option (as defined herein) shall be assumed by Parent as a Parent Option (as defined herein). Each Company Option so assumed by Parent pursuant to this Section 1.6(c) shall continue to have, and be subject to, the same terms and conditions (including vesting terms) set forth in the Company's Second Amended and Restated 1999 Stock Incentive Plan (the "Plan"), and the option agreements relating thereto, as in effect immediately prior to the Effective Time, except that (i) such assumed Company Option will be exercisable for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock that were issuable upon exercise of such Company Option (whether or not then exercisable or vested) immediately prior to the Effective Time multiplied by the Option Exchange Ratio, rounded -3- down to the nearest whole number of shares of Parent Common Stock, and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Option shall be equal to the quotient obtained by dividing the option exercise price of the Company Option immediately prior to the Closing Date by the Option Exchange Ratio, rounded up to the nearest whole cent; provided, however, that in the case of any Company Option to which Section 421 of the Code applies by reason of its qualification under Section 422 of the Code, the option exercise price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in order to comply with Section 424 of the Code; provided, further, that in the case of any Company Option held by an Employee who is not employed by the Company or a Company Subsidiary immediately prior to the Effective Time, only vested Company Options (as determined at the Effective Time after giving effect to any acceleration resulting from the transaction) shall be assumed by Parent pursuant to this Section 1.6(c). (ii) At the Effective Time, each outstanding Company Warrant, if any, shall not be assumed by Parent and shall either be exercised or terminated. (iii) Prior to the Effective Time, the Company shall take all action necessary to effect the transactions anticipated by this Section 1.6(c) under all Company Option agreements and Company Warrant agreements, if any, and any other plan or arrangement of the Company. (d) Withholding Taxes. The requisite number of shares of Parent Common Stock issuable pursuant to Section 1.6(a) hereof shall be subject to, and reduced by, the amount of any state, federal and foreign withholding taxes incurred (and not previously paid by or on behalf of such Stockholder or the Company) in connection with the acquisition of Company Capital Stock upon the exercise of Company Options, upon the lapsing of repurchase rights in respect of shares of Company Common Stock, or upon payment of a bonus in the form of Company Common Stock, if any, to such Stockholder. (e) Capital Stock of Sub. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Sub, the Company or holders of any of the capital stock of Sub, each share of Common Stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of Common Stock of the Surviving Corporation. Each stock certificate of Sub evidencing ownership of any such shares shall continue to evidence ownership of such shares of capital stock of the Surviving Corporation. (f) Shares Subject to Vesting. If any shares of Company Common Stock issued and outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable stock restriction agreement or other agreement with the Company, then the Stock Consideration and Cash Consideration issued in exchange for such shares of Company Restricted Stock (as defined herein) shall also be unvested and subject to the same repurchase option, risk of forfeiture or other condition (including any requirement that any unvested shares be held in escrow). The certificate representing such shares of Parent Common Stock may accordingly be marked with appropriate legends in the discretion of -4- Parent. Such repurchase option, risk of forfeiture or other condition shall be applied pro rata to both the Stock Consideration (with the shares of Parent Common Stock valued at the Trading Price) and the Cash Consideration, and the Cash Consideration payable upon conversion of each share of Company Restricted Stock shall be subject to the same vesting schedule as the related Parent Common Stock issued upon conversion of the corresponding share of Company Restricted Stock and shall be paid at the same time as such Parent Common Stock vests. The Company shall take all actions that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any repurchase option or other right set forth in any applicable stock restriction agreement or other agreement and retain any Cash Consideration payable with respect to shares of Company Restricted Stock. 1.7 Dissenting Shares. (a) Notwithstanding any other provisions of this Agreement to the contrary, any shares of Company Common Stock outstanding immediately prior to the Effective Time held by a holder who has demanded and perfected the right for appraisal of those shares in accordance with the provisions of Section 262 of the Delaware Law and as of the Effective Time has not withdrawn or lost such right to such appraisal ("Dissenting Shares") shall not be converted into or represent a right to receive the Merger Consideration set forth in Section 1.6 hereof, but the holder shall only be entitled to such rights as are provided by Delaware Law. (b) Notwithstanding the provisions of Section 1.7(a) hereof, if any holder of Dissenting Shares shall effectively withdraw or lose (through failure to perfect or otherwise) such holder's appraisal rights under Delaware Law, then, as of the later of the Effective Time and the occurrence of such event, such holder's shares shall automatically be converted into and represent only the right to receive the Merger Consideration set forth in Section 1.6 hereof, without interest thereon, upon surrender of the certificate or certificates representing such shares. (c) The Company shall give Parent (i) prompt notice of any written demand for appraisal received by the Company pursuant to the applicable provisions of Delaware Law, and (ii) the opportunity to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any such demands or offer to settle or settle any such demands. 1.8 Surrender of Certificates. (a) Exchange Agent. Wells Fargo Bank N.A. or such other bank or trust company designated by Parent and reasonably satisfactory to the Company and Siemens shall serve as the exchange agent (the "Exchange Agent") for the Merger. As of the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent for exchange in accordance with this Article I the Total Cash Consideration (less the aggregate amount of Cash Consideration paid by Parent directly to Siemens at Closing under Section 1.6(b) hereto) and the Total Stock Consideration issuable pursuant to Section 1.6 hereof in exchange for outstanding shares of Company Common Stock (the "Exchange Fund"). Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any cash in lieu of fractional shares pursuant to Section 1.8(f) -5- hereof and any dividends and other distributions pursuant to Section 1.8(c) hereof. The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for shares of Company Common Stock pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 1.8(c) and 1.8(f) hereof, the Exchange Fund shall not be used for any other purpose. (b) Exchange Procedures. Promptly after the Effective Time, Parent shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the "Company Stock Certificates") (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Company Stock Certificates shall pass, only upon proper delivery of the Company Stock Certificates to the Exchange Agent and shall be in customary form) and (ii) instructions for use in effecting the surrender of the Company Stock Certificates in exchange for the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Company Stock Certificates. Upon surrender of a Company Stock Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor, the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Company Stock Certificate and any cash in lieu of fractional shares pursuant to Section 1.8(f) hereof and any dividends or other distributions to which such holder is entitled pursuant to Section 1.8(c) hereof, and the Company Stock Certificate so surrendered shall be canceled. Until so surrendered, each Company Stock Certificate outstanding after the Effective Time shall be deemed from and for all corporate purposes, to evidence the right to receive upon such surrender the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Company Stock Certificate and any cash in lieu of fractional shares pursuant to Section 1.8(f) hereof and any dividends on other distributions to which such holder is entitled pursuant to Section 1.8(c) hereof. (c) Distributions With Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Parent Common Stock, with a record date after the Effective Time, shall be paid to the holder of any unsurrendered Company Stock Certificate until the holder of such Company Stock Certificate shall surrender such Company Stock Certificate. Subject to the effect of escheat, tax or other applicable law, following surrender of any such Company Stock Certificate, there shall be paid to such holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) promptly, the amount of any cash due pursuant to Section 1.6 hereof and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date at or after the Effective Time but prior to such surrender and a payment date subsequent to such surrender, payable with respect to such whole shares of Parent Common Stock at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock. -6- (d) Transfers of Ownership. If any certificate for shares of Parent Common Stock is to be issued in a name other than that in which the certificate surrendered in exchange therefor is registered, it will be a condition of the issuance and/or delivery thereof that the certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange will have paid to Parent or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for shares of Parent Common Stock in any name other than that of the registered holder of the certificate surrendered, or established to the satisfaction of Parent or any agent designated by it that such tax has been paid or is not payable. (e) No Liability. Notwithstanding anything to the contrary in this Section 1.8, neither the Exchange Agent, the Surviving Corporation, nor any party hereto shall be liable to any holder of shares of Company Common Stock for any such shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (f) No Fractional Shares. No certificates representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Company Stock Certificates. Each holder of shares of Company Common Stock who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Parent Common Stock multiplied by the Trading Price. 1.9 No Further Ownership Rights in Company Common Stock. The Merger Consideration paid in respect of the surrender for exchange of Company Stock Certificates in accordance with the terms hereof (including any cash in lieu of fractional shares pursuant to Section 1.8(f) hereof and any dividends or distributions paid pursuant to Section 1.8(c) hereof) shall be deemed to be full satisfaction of all rights pertaining to such shares of Company Common Stock. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter, there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Common Stock which were outstanding immediately prior to the Effective Time. On or after the Effective Time, any Company Stock Certificates presented to the Exchange Agent, Parent or the Surviving Corporation shall be converted into the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Company Stock Certificates and any cash in lieu of fractional shares pursuant to Section 1.8(f) hereof and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 1.8(c). 1.10 Lost, Stolen or Destroyed Certificates. If any Company Stock Certificate shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed certificates, upon the making of an affidavit of that fact by the holder thereof the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Company Stock Certificates and any cash in lieu of fractional shares pursuant to Section 1.8(f) hereof and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 1.8(c), provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the Stockholder who is the owner of such lost, stolen or destroyed certificates to either (i) deliver a bond in such amount as it may reasonably direct or (ii) provide an -7- indemnification agreement in a form and substance acceptable to Parent, against any claim that may be made against Parent or the Exchange Agent with respect to the Company Stock Certificates alleged to have been lost, stolen or destroyed. 1.11 Antidilution Provision. In the event Parent changes (or establishes a record date that occurs prior to the Effective Time for changing) the number of shares of Parent Common Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction with respect to the outstanding shares of Parent Common Stock, the Stock Exchange Ratio and the Option Exchange Ratio shall be proportionately adjusted, as applicable, to reflect such stock split, stock dividend, recapitalization, subdivision, reclassification, combination, exchange of shares or similar transaction. In addition, in the event Parent pays (or establishes a record date that occurs prior to the Effective Time for payment of) an extraordinary dividend on, or makes any other extraordinary distribution in respect of, Parent Common Stock, the Stock Exchange Ratio and the Option Exchange Ratio shall be appropriately adjusted to reflect such dividend or distribution. 1.12 Taking of Necessary Action; Further Action. If at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, Parent, Sub, and the officers and directors of the Company, Parent and Sub are fully authorized in the name of their respective corporations or otherwise to take, and will take, all such lawful and necessary action. ARTICLE II CERTAIN REPRESENTATIONS AND WARRANTIES OF SIEMENS Siemens hereby represents and warrants to each of Parent and Sub as follows: 2.1 Organization of Siemens. Siemens is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware.

Subject to the approval of the Supervisory Board of Siemens AG (the "Siemens AG Approval"), the execution and delivery of this Agreement and any Related Agreements to which Siemens is a party and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate action on the part of Siemens, and no further action is required on the part of Siemens to authorize the Agreement and any Related Agreements to which it is a party and the transactions contemplated hereby and thereby. This Agreement and each of the Related Agreements to which Siemens is a party has been duly executed and delivered by Siemens and assuming the due authorization, execution and delivery by the other parties hereto and thereto, constitute the valid and binding obligations of Siemens, -8- enforceable (in the case of this Agreement, the Stockholder Agreement and the Distribution Agreement (as defined herein) only) against Siemens in accordance with their respective terms, except as such enforceability may be subject to the laws of general application relating to bankruptcy, insolvency, and the relief of debtors and rules of law governing specific performance, injunctive relief, or other equitable remedies. 2.3 No Conflict.

Notwithstanding anything in this section, nothing herein shall permit an Indemnifying Party to delay or refrain from making any payment to any Indemnified Party because of the availability or alleged availability of any insurance policy or Insurance Proceeds or Tax savings.

(a) Any Indemnified Party seeking indemnification pursuant to Article VIII shall give prompt notice in writing to the Indemnifying Party of any matter which any such Indemnified Party has determined has given rise to a right of indemnification under this Agreement, stating the amount of the Loss, if known, and method of computation thereof (the "Claim Notice"); provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations hereunder, except to the extent such Indemnifying Party is materially prejudiced by such failure. Except as set forth below, upon notice duly given by a Parent Indemnified Party to an Indemnifying Party of a Claim Notice, such Indemnifying Party shall pay the Parent Indemnified Party as promptly as practicable: (i) an amount in cash equal to the Cash Portion (as defined herein) of such Losses and (ii) a number of shares of Parent Common Stock equal to the Stock Portion (as defined herein) of such Losses (with such shares valued at the Indemnification Price (as defined herein)). Except as set forth below, upon notice duly given by a Siemens Indemnified Party to an Indemnifying Party of a Claim Notice, such Indemnifying Party shall pay the Siemens Indemnified Party as promptly as practicable an amount in cash equal to such Losses. If the Indemnifying Party does not dispute its obligation to indemnify the Indemnified Party against any Losses set forth in the Claim Notice, within 30 days after receipt of such notice, such Indemnifying Party shall be deemed -53- to have irrevocably acknowledged that the Indemnified Party is entitled to the full amount of the Losses set forth in such notice. For purposes of this Agreement, "Cash Portion" shall mean the percentage (rounded up to the nearest whole number) that the Cash Consideration represents of the Total Consideration (with the Stock Consideration valued at the Trading Price) as of the Closing Date, and "Stock Portion" shall mean the percentage (rounded down to the nearest whole number) that the Stock Consideration (as valued at the Trading Price) represents of the Total Consideration as of the Closing Date. For purposes of this Agreement, "Indemnification Price" shall mean the average closing sale price of one share of Parent Common Stock as reported on Nasdaq for the ten (10) consecutive trading days ending three (3) trading days immediately preceding the date it is determined that such claim for indemnification is owed by the Indemnifying Party. (b) Resolution of Conflicts; Arbitration. (i) If, within 30 days after notice duly given to the Indemnifying Party of such a Claim Notice, such Indemnifying Party disputes its obligations to indemnify the Indemnified Party against any Losses set forth in such notice and such Indemnifying Party notifies the Indemnified Party in writing of such dispute, the Indemnified Party and the Indemnifying Party hereby agree to negotiate in good faith in an attempt to resolve such dispute. (ii) If such dispute is not resolved within 30 days after notice duly given to the Indemnified Party of such dispute, the Indemnified Party may demand arbitration of such dispute unless the amount of the Loss relates to a Third Party Claim, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration, and in either such event the matter shall be settled by arbitration conducted by one arbitrator mutually agreeable to Indemnified Party and the Indemnifying Party. In the event that, within 30 days after submission of any dispute to arbitration, Indemnified Party and the Indemnifying Party cannot mutually agree on one arbitrator, then, within 15 days after the end of such 30 day period, the Indemnified Party and the Indemnifying Party shall each select one arbitrator. The two arbitrators so selected shall select a third arbitrator. If the Indemnifying Party fails to select an arbitrator during this 15 day period, then the parties hereto agree that the arbitration will be conducted by one arbitrator selected by the Indemnified Party. (iii) Any such arbitration shall be held in New York, New York, under the rules then in effect of the American Arbitration Association. The arbitrator(s) shall determine how all expenses relating to the arbitration shall be paid, including without limitation, the respective expenses of each party, the fees of each arbitrator and the administrative fee of the American Arbitration Association. The arbitrator or arbitrators, as the case may be, shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrator or majority of the three arbitrators, as the case may be, to discover relevant information from the opposing parties about the subject matter of the dispute. The arbitrator, or a majority of the three arbitrators, as the case may be, shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys' fees and costs, to the same extent as a competent court of law or equity, should the arbitrators or a majority of the three arbitrators, as the case may be, determine that discovery was sought without substantial justification or that discovery was refused or objected to -54- without substantial justification. The decision of the arbitrator or a majority of the three arbitrators, as the case may be, as to the validity and amount of any claim in such dispute shall be final, binding, and conclusive upon the parties hereto. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s). Within thirty (30) days of a decision of the arbitrator(s) requiring payment by one party to another, such party shall make the payment to such other party. (iv) Judgment upon any award rendered by the arbitrator(s) may be entered in any court having jurisdiction. (c) Notices and Defense of Actions. (i) The obligations and Liabilities of the Indemnifying Party under this Article VIII with respect to Losses arising from claims of any third party which are subject to the indemnification provided for in this Article VIII ("Third Party Claims") shall be governed by and contingent upon the additional terms and conditions set forth in this Article VIII. If an Indemnified Party shall receive notice of any Third Party Claim in writing, the Indemnified Party shall give the Indemnifying Party prompt notice of such Third Party Claim in writing; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations hereunder, except to the extent such Indemnifying Party is materially prejudiced by such failure. (ii) The Indemnifying Party shall have the right to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if (i) it gives notice of its intention to do so to the Indemnified Party within 30 days of the duly given notice from the Indemnified Party and (ii) it acknowledges in writing that such Third Party Claim is a claim subject to indemnification hereunder. In the event the Indemnifying Party exercises the right to undertake any such defense against any such Third Party Claim as provided above, the Indemnified Party may participate in such defense, but the expenses of the Indemnified Party shall be paid by the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party all witnesses, pertinent records, materials and information in the Indemnified Party's possession or under the Indemnified Party's control relating thereto as is reasonably required by the Indemnifying Party, and the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith. Notwithstanding anything to the contrary contained in the foregoing, if the Indemnifying Party exercises the right to undertake such defense against any such Third Party Claim and the Indemnifying Party and the Indemnified Party have adverse or potentially adverse interests in the Third Party Claim, the Indemnified Party may participate in such defense and employ separate counsel, at the Indemnifying Party's expense, but the Indemnifying Party shall control such defense. No such Third Party Claim may be settled by the Indemnifying Party without the written consent of the Indemnified Party, which consent shall not be unreasonably withheld, unless such settlement involves only the payment of money (which payment obligation is borne exclusively by the Indemnifying Party), involves a full and unconditional release of the Indemnified Party and does not contain any prohibitions, limitations or restrictions on the conduct of the Indemnified Party's business. -55- (iii) If the Indemnifying Party shall fail to undertake any such defense, the Indemnified Party shall have the right to assume and control the defense thereof, at the Indemnifying Party's expense, and through counsel of the Indemnified Party's choice. In the event the Indemnified Party is conducting the defense against any such Third Party Claim, the Indemnifying Party (i) may participate in such defense, but the expenses of the Indemnifying Party shall be paid by the Indemnifying Party and (ii) shall cooperate with the Indemnified Party in such defense and make available to the Indemnified Party at the Indemnifying Party's expense, all such witnesses, records, materials and information in the Indemnifying Party's possession or under the Indemnifying Party's control relating thereto as is reasonably required by the Indemnified Party. If the Indemnified Party assumes the defense against any such Third Party Claim, such Indemnified Party agrees to keep the Indemnifying Party informed as to the status of such Third Party Claim. If the Indemnified Party assumes the defense against any such Third Party Claim and proposes to settle such claim or proceeding prior to a final judgment thereon or to forego any appeal with respect thereto, then the Indemnified Party shall give the Indemnifying Party prompt written notice thereof and shall not settle any such Third Party claim without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld). 8.4 Maximum Payments. (a) The maximum amount a Parent Indemnified Party may recover from Siemens for Losses pursuant to Section 8.2(a) hereof shall be limited to an amount equal to twenty-five percent (25%) of the Total Consideration (with the Stock Consideration valued at the Trading Price). (b) The maximum amount a Siemens Indemnified Party may recover from Parent for Losses pursuant to Section 8.2(c) hereof shall be limited to an amount equal to twenty-five percent (25%) of the Total Consideration (with the Stock Consideration valued at the Trading Price). ARTICLE IX TAX MATTERS 9.1 Indemnity. (a) Siemens Corporation agrees to indemnify and hold harmless Parent and its officers, directors, and affiliates, including the Surviving Corporation (the "Parent Indemnified Parties") against the following Income Taxes and, except as otherwise provided in Section 9.4, against any loss, damage, liability or expense, including reasonable fees for attorneys and other outside consultants, incurred in contesting or otherwise in connection with any such Income Taxes: (i) Taxes imposed on the Company or any Company Subsidiary with respect to taxable periods ending on or before the Closing Date (including but not limited to the Taxes attributable to the Voice Transaction); (ii) with respect to taxable periods beginning on or before the Closing Date and ending after the Closing Date, Taxes imposed on the Company or any Company Subsidiary which are allocable, pursuant to Section 9.1(b), to the portion of such period ending on the Closing Date; and (iii) Taxes imposed on any member of any affiliated group with which any of the Company and the Company Subsidiaries file or have filed a Return on a consolidated or combined basis for a taxable -56- period ending on or before the Closing Date. Parent shall be responsible for Taxes and associated expenses not allocated to Siemens pursuant to the first sentence hereof. (b) In the case of Taxes that are payable with respect to a taxable period that begins before the Closing Date and ends after the Closing Date, the portion of any such Tax that is allocable to the portion of the period ending on the Closing Date shall be: (i) in the case of Taxes that are either (x) based upon or related to income or receipts, or (y) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible) deemed equal to the amount which would be payable if the taxable year ended with the Closing Date; and (ii) in the case of Taxes imposed on a periodic basis with respect to the assets of the Company or any Company Subsidiary, or otherwise measured by the level of any item, deemed to be the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction the numerator of which is the number of calendar days in the period ending on the Closing Date and the denominator of which is the number of calendar days in the entire period. 9.2 Returns and Payments. (a) From the date of this Agreement through and after the Closing Date, Siemens shall prepare and file or otherwise furnish in proper form to the appropriate Governmental Entity (or cause to be prepared and filed or so furnished) in a timely manner all Tax returns, reports and forms ("Returns") relating to the Company and its Company Subsidiaries that are due on or before or relate to any taxable period ending on or before the Closing Date (and Parent shall do the same with respect to any taxable period ending after the Closing Date). Returns of the Company and its Company Subsidiaries not yet filed for any taxable period that begins before the Closing Date shall be prepared in a manner consistent with past practices employed with respect to the Company and its Company Subsidiaries. With respect to any Return required to be filed by Parent or Siemens with respect to the Company and its Company Subsidiaries and as to which an amount of Tax is allocable to the other party under Section 9.1(b), the filing party shall provide the other party and its authorized representatives with a copy of such completed Return and a statement certifying the amount of Tax shown on such Return that is allocable to such other party pursuant to Section 9.1(b), together with appropriate supporting information and schedules at least 10 business days prior to the due date (including any extension thereof) for the filing of such Return, and such other party and its authorized representatives shall have the right to review and comment on such Return and statement prior to the filing of such Return. (b) Siemens shall pay or cause to be paid when due and payable all Taxes with respect to the Company and each Company Subsidiary which are the responsibility of Siemens under this Article IX and Parent shall so pay or cause to be paid Taxes for any taxable period after the Closing Date which are the responsibility of Parent under this Agreement (subject to its right of -57- indemnification from Siemens for Taxes attributable to the portion of any Tax period that includes the Closing Date pursuant to Section 9.1(a) and Section 9.1(b). 9.3 Refunds. Any Tax refund (including any interest with respect thereto) relating to the Company or any Company Subsidiary for any taxable period ending on or before the Closing Date shall be the property of Siemens, and if received by Parent, the Company or any Company Subsidiary, shall be paid over promptly to Siemens. Parent shall not, and shall not cause or permit any of the Company or its Company Subsidiaries to, carryback any net operating loss, capital loss, Tax credit or other similar Tax attribute attributable to Parent or any of the Company or its Company Subsidiaries from a taxable period ending after the Closing Date into a taxable period ending on or prior to the Closing Date of Siemens or the Company and its Company Subsidiaries, without Siemens' prior written consent, which consent may be withheld in Siemens' sole and absolute discretion. In the absence of Siemens' prior written consent, Siemens shall not be required to pay to Parent or any Company or its Company Subsidiary any refund or credit of Taxes that results from the carryback to any taxable period ending on or prior to the Closing Date of any net operating loss, capital loss, Tax credit or other similar Tax attribute attributable to Parent or any of the Company or its Company Subsidiaries from a taxable period ending after the Closing Date. 9.4 Contests. (a) After the Closing, Parent will promptly notify within 10 days Siemens in writing of any written notice of a proposed assessment or claim in an audit or administrative or judicial proceeding of Parent or of the Company or any Company Subsidiary which, if determined adversely to the taxpayer, would be grounds for indemnification under this Article IX; provided, however, that a failure to give such notice will not affect Parent's right to indemnification under this Article IX except to the extent that such that failure effectively precluded Siemens from avoiding all or a portion of the Tax liability in question. (b) In the case of an audit or administrative or judicial proceeding that relates to periods ending on or before the Closing Date, provided that Siemens acknowledges in writing its liability under this Agreement to hold Parent, the Company and its Company Subsidiaries harmless against the full amount of any adjustment which may be made as a result of such audit or proceeding that relates to periods ending on or before the Closing Date (or, in the case of any taxable year that includes the Closing Date, against an adjustment allocable under Section 9.1(b) to the portion of such year ending on or before the Closing Date), Siemens shall have the right at its expense to participate in and control the conduct of such audit or proceeding but only to the extent that such audit or proceeding relates solely to a potential adjustment for which Siemens could be held liable hereunder; Parent also may participate in any such audit or proceeding and, if Siemens does not assume the defense of any such audit or proceeding, Parent may defend the same in such manner as it may deem appropriate, including, but not limited to, settling such audit or proceeding after giving ten business days' prior written notice to Siemens setting forth the terms and conditions of settlement. -58- (c) With respect to issues relating to a potential adjustment for which both Siemens and Parent or the Company or any Company Subsidiary could be liable, each party may participate in the audit or proceeding. (d) Neither Parent nor Siemens shall enter into any compromise or agree to settle any claim pursuant to any Tax audit or proceeding which would adversely affect the other party for such year or a subsequent year without the written consent of the other party, which consent may not be unreasonably withheld. Parent and Siemens agree to cooperate, and Parent agrees to cause the Company and its Company Subsidiaries to cooperate, in the defense against or compromise of any claim in any audit or proceeding. 9.5 Cooperation and Exchange of Information. Siemens and Parent will provide each other with such cooperation and information as either of them reasonably may request of the other (and Parent shall cause the Company and its Company Subsidiaries to provide such cooperation and information) in filing any Tax return, report or form, amended Tax return or claim for refund, determining any liability for Taxes or a right to a refund of Taxes or participating in or conducting any audit or other proceeding in respect of Taxes relating to the Company and its Company Subsidiaries. Such cooperation and information shall include providing copies of relevant Tax returns or portions thereof, together with accompanying schedules and related work papers and documents relating to rulings or other determinations by taxing authorities. Siemens shall make its employees available, and Parent shall make its employees available (and shall cause the employees of the Company and its Company Subsidiaries to be available) on a mutually convenient basis to provide explanations of any documents or information provided hereunder. Parent will retain and will cause the Company and its Company Subsidiaries to retain all Tax returns, schedules and work papers and all material records or other documents in its possession relating to Tax matters of the Company and its Company Subsidiaries for the taxable period first ending after the Closing Date and for all prior taxable periods until the later of (i) the expiration of the statute of limitations of the taxable periods to which such Tax returns and other documents relate, without regard to extensions, or (ii) seven years following the due date (without extension) for such Tax returns. After such time, before Parent shall dispose of any such documents, Parent shall, by 90 days' prior written notice to Siemens, give Siemens the opportunity (at Siemens' expense) to remove and retain all or any part of such documents as Siemens may select. Any information obtained under this Section 9.5 shall be kept confidential, except as may be otherwise necessary in connection with the filing of returns or claims for refund or in conducting an audit or other proceeding. 9.6 Conveyance Taxes. Siemens and Parent shall each pay one half of any real property transfer or gains, sales, use, transfer, value added, stock transfer, and stamp taxes, any transfer, recording, registration, and other fees, and any similar Taxes which become payable in connection with the transactions contemplated by this Agreement, and shall file such applications and documents as shall permit any such Tax to be assessed and paid on or prior to the Closing Date in accordance with any available per sale filing procedure. Parent shall execute and deliver all instruments and certificates necessary to enable Siemens to comply with the foregoing. -59- 9.7 Miscellaneous. (a) Siemens and Parent agree to treat all payments made by either of them to or for the benefit of the other (including any payments to the Company or any Company Subsidiary) under this Article IX, under other indemnity provisions of this Agreement (including, without limitation, Article VIII) and for any misrepresentations or breaches of warranties or covenants as adjustments to the purchase price or as capital contributions for Tax purposes and that such treatment shall govern for purposes hereof except to the extent that the Laws of a particular jurisdiction provide otherwise, in which case such payments shall be made in an amount sufficient to indemnify the relevant party on an after-Tax basis. (b) Any indemnifiable amount otherwise payable by Siemens shall be reduced by any Tax benefit actually realized by Parent, the Company or any of its Company Subsidiaries in a taxable period or portion thereof ending after the Closing Date (a "Post-Closing Date Tax Benefit") as a result of either an adjustment to Taxes for which Siemens is responsible under Article IX (such as a timing adjustment resulting in a Tax deduction for the Company or any Company Subsidiary for a period after the Closing Date) or a Tax deduction resulting from an indemnifiable payment. If a payment is made by Siemens in accordance with its indemnification obligation, and if in a subsequent taxable year a Post-Closing Date Tax Benefit that was not previously taken into account pursuant to the preceding sentence to reduce an amount otherwise payable by Siemens is actually realized by Parent, the Company or any Company Subsidiary, Parent shall pay to Siemens at the time of such realization the amount of such Post-Closing Date Tax Benefit to the extent that the Post-Closing Date Tax Benefit would have resulted in a reduction in the amount paid by Siemens if the Post-Closing Date Tax Benefit had been obtained in the year of such payment. A Post-Closing Date Tax Benefit will be considered to be realized for purposes of this Section 9.7(b) at the time that it is reflected on a Tax return of Parent, the Company or any Company Subsidiary. (c) Any tax sharing agreement or arrangement between Siemens and any of the Company or Company Subsidiaries shall be terminated in its entirety immediately prior to the Closing and neither Company nor any Company Subsidiary will have any liability or obligation under such agreement or arrangement after the Closing. (d) Notwithstanding any provision in this Agreement to the contrary, the obligations of Siemens to indemnify and hold harmless Parent, the Company and its Company Subsidiaries pursuant to this Article IX shall terminate at the close of business on the day following the expiration of the applicable statute of limitations with respect to the Tax liabilities in question (giving effect to any waiver, mitigation or extension thereof). (e) From and after the Closing Date, Siemens shall not without the prior written consent of Parent (which may, in its sole and absolute discretion, withhold such consent) make, or cause or permit to be made, any material Tax election that would affect any of the Company or any Company Subsidiaries. (f) To the extent any provision of Article VIII is inconsistent with the provisions of this Article IX, the provisions of this Article IX shall govern. -60- For purposes of this Article IX, "Parent" and "Siemens," respectively, shall include each member of the affiliated group of corporations of which it is or becomes a member (other than the Company and its Company Subsidiaries, except to the extent expressly referenced).

In the event of termination of this Agreement as provided in Section 10.1 hereof, this Agreement shall forthwith become void and there shall be no liability or obligation on the part of Parent, the Company or Siemens, or their respective officers, directors or stockholders, if applicable; provided, however, that each party hereto shall remain liable for any willful breaches of this Agreement prior to its termination; and provided further, however, that, the provisions of Sections 6.5, 6.6 and 6.7 hereof, Article XI hereof and this Section 10.2 shall remain in full force and effect and survive any termination of this Agreement pursuant to the terms of this Article X. 10.3 Amendment. This Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed by or on behalf of the parties hereto. 10.4 Extension; Waiver. At any time prior to the Closing, Parent, on the one hand, and the Company and Siemens, on the other hand, may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations of the other party 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 such party contained herein.
