NOW, THEREFORE, in consideration of the covenants, promises and representations set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

ARTICLE I
THE MERGER

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

1.2 Effective Time; Closing. Subject to the provisions of this Agreement, the parties hereto shall cause the Merger to be consummated by filing a Certificate of Merger with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL (the “Certificate of Merger“) (the time of such filing with the Secretary of State of the State of Delaware (or such later time as may be agreed in writing by Novadigm and Parent and specified in the Certificate of Merger) being the “Effective Time“) as soon as practicable on or after the Closing Date (as defined below). The closing of the Merger (the “Closing“) shall take place at the offices of Wilson Sonsini Goodrich & Rosati, Professional Corporation, located at 650 Page Mill Road, Palo Alto, California, at a time and date to be specified by the parties, which shall be no later than the second business day after the satisfaction or waiver of the conditions set forth in Article VI, or at such other time, date and location as the parties hereto agree in writing (the “Closing Date“).

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger and Section 259 of the DGCL. In accordance with the DGCL, all of the rights, privileges, property, powers and franchises of Novadigm and Merger Sub shall vest in the Surviving Corporation, and all of the debts, liabilities and duties of Novadigm and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Certificate of Incorporation and Bylaws. At the Effective Time, the Certificate of Incorporation of Novadigm shall be amended and restated in its entirety to be identical to the Certificate of Incorporation attached as Exhibit B

hereto, until thereafter amended in accordance with Delaware Law and as provided in such Certificate of Incorporation. At the Effective Time, the Bylaws of Novadigm shall be amended and restated in their entirety to be identical to the Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, until thereafter amended in accordance with Delaware Law and as provided in such Bylaws.

1.5 Directors and Officers. The initial directors of the Surviving Corporation shall be the directors of Merger Sub immediately prior to the Effective Time, until their respective successors are duly elected or appointed and qualified or their earlier death, resignation or removal. The initial officers of the Surviving Corporation shall be the officers of Merger Sub immediately prior to the Effective Time, until their respective successors are duly appointed or their earlier death, resignation or removal.

1.6 Effect on Capital Stock. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, Novadigm or the holders of any shares of capital stock of Novadigm, the following shall occur:

(a) Novadigm Common Stock. Each share of the Common Stock, par value $0.001 per share, of Novadigm (“Novadigm Common Stock“) issued and outstanding immediately prior to the Effective Time, other than any (i) shares of Novadigm Common Stock to be canceled pursuant to Section 1.6(b) and (ii) Appraisal Shares (as defined in Section 1.6(e)), will be canceled and extinguished and automatically converted into the right to receive $6.10 in cash, without interest (the “Merger Consideration“), upon surrender of the certificate representing such share of Novadigm Common Stock in the manner provided in Section 1.7 (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit and bond, if required, in the manner provided in Section 1.9). At the Effective Time, such shares of Novadigm Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such shares of Novadigm Common Stock (a “Certificate“) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration. The right of any holder of any share of Novadigm Common Stock to receive the Merger Consideration shall be subject to and reduced by the amount of any withholding that is required under applicable tax law.

(b) Cancellation of Treasury and Parent Owned Stock. Each share of Novadigm Common Stock held by Novadigm or Parent or any direct or indirect wholly-owned Subsidiary (as defined in Section 2.1(a)) of Novadigm or of Parent immediately prior to the Effective Time shall be canceled and

extinguished without any conversion thereof and no consideration shall be delivered therefor.

(c) Capital Stock of Merger Sub. Each share of common stock, par value $0.001 per share, of Merger Sub (the “Merger Sub Common Stock“) issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation.

(d) Stock Options; Employee Stock Purchase Plans. At the Effective Time, all Novadigm Options (as defined in Section 2.2(b)) outstanding under the Novadigm Stock Plans (as defined in Section 2.2(b)) shall be treated in accordance with Section 5.9. Rights outstanding under the Novadigm Purchase Plan (as defined in Section 2.2(b)) shall be treated as set forth in Section 5.9(c).

(e) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares of Novadigm Common Stock issued and outstanding immediately prior to the Effective Time that are held by any holder who is entitled to demand and properly demands appraisal of such shares (the “Appraisal Shares“) pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (“Section 262“) shall not be converted into the right to receive the Merger Consideration as provided in Section 1.6(a), but instead such holder shall be entitled to payment of the fair value of such shares in accordance with the provisions of Section 262. At the Effective Time, the Appraisal Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such shares in accordance with the provisions of Section 262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262 shall cease and such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 1.6(a). Novadigm shall serve prompt notice to Parent of any demands for appraisal of any shares of Novadigm Common Stock, withdrawals of such demands and any other instruments served pursuant to the DGCL received by Novadigm, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, Novadigm shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do or commit to do any of the foregoing.

1.7 Surrender of Certificates.

(a) Paying Agent. Parent shall select Computershare Trust Company of New York or another institution reasonably satisfactory to Novadigm to act as the Paying Agent (the “Paying Agent“) in the Merger.

(b) Parent to Provide Merger Consideration. Prior to the Effective Time, Parent shall enter into an agreement with the Paying Agent, reasonably satisfactory to Novadigm, which shall provide that Parent shall make available or cause the Merger Sub to make available to the Paying Agent for payment in accordance with this Article I, funds for the benefit of the holders of Novadigm Common Stock in amounts and at the times necessary for the payment of the Merger Consideration pursuant to Section 1.6(a) and in accordance with Section 1.7(c) upon surrender of Certificates, it being understood that any and all interest earned on funds made available to the Paying Agent pursuant to this Agreement shall be turned over to Parent. Any cash deposited with the Paying Agent shall hereinafter be referred to as the “Exchange Fund.”

(c) Exchange Procedures. As promptly as practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record (as of the Effective Time) of a Certificate or Certificates that immediately prior to the Effective Time represented outstanding shares of Novadigm Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.6(a): (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of Certificates for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificates shall be entitled to receive, as promptly as practicable, in exchange therefor the amount of cash (after taking into account all Certificates surrendered by such holder) to which such holder is entitled pursuant to Section 1.6(a) and the Certificates so surrendered shall forthwith be canceled.

(d) Transfers of Ownership. If payment of the Merger Consideration is to be made to a Person (as defined in Section 8.3(c)) other than a Person in whose name in which the Certificates surrendered in exchange therefor are registered, it will be a condition of the payment thereof that the Certificates so surrendered will be properly endorsed and otherwise in proper form for transfer

and that the Persons requesting such exchange will have paid to Parent or any agent designated by it any transfer or other Taxes (as defined in Section 2.6(a)) required by reason of the payment to a Person other than the registered holder of the Certificates surrendered, or established to the reasonable satisfaction of Parent or any agent designated by it that such Tax has been paid or is not payable.

(e) Withholding. Each of Parent, the Paying Agent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Novadigm Common Stock such amounts as may be required to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as amended (the “Code“), or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirement (as defined in Section 2.2(d)). To the extent such amounts are so deducted or withheld, (i) they shall be timely paid to the appropriate governmental authority, and (ii) the amount of such consideration shall be treated for all purposes under this Agreement as having been paid to the Person to whom such consideration would otherwise have been paid.

(f) No Liability. Notwithstanding anything to the contrary in this Section 1.7, neither Parent, Merger Sub, the Paying Agent, the Surviving Corporation nor any party hereto shall be liable to any Person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(g) Investment of Exchange Fund. The Paying Agent shall invest any cash included in the Exchange Fund as directed by Parent on a daily basis, provided that no such investment or loss thereon shall affect the amounts payable to Novadigm stockholders pursuant to this Article I. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable to Novadigm stockholders pursuant to this Article I shall promptly be paid to Parent.

(h) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates six (6) months after the Effective Time shall, at the request of Parent, be delivered to Parent or otherwise on the instruction of Parent, and any holders of the Certificates who have not surrendered such Certificates in compliance with this Section 1.7 shall after such delivery to Parent look only to Parent for the Merger Consideration pursuant to Section 1.6(a), with respect to the shares of Novadigm Common Stock formerly represented thereby.

1.8 No Further Ownership Rights in Novadigm Common Stock. All Merger Consideration paid upon the surrender for exchange of shares of

Novadigm Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Novadigm Common Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Novadigm Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I.

1.9 Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, Parent shall cause the Paying Agent to deliver in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such Merger Consideration as may be required pursuant to Section 1.6(a); provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to indemnify Parent, Novadigm, the Paying Agent or any of their respective representatives or agents with respect to the Certificates alleged to have been lost, stolen or destroyed, and require such owner to deliver a bond in such sum as Parent may reasonably request as indemnity against any such claim.

1.10 Further Action. At and after the Effective Time, the officers and directors of Parent and the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of Novadigm and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Novadigm and Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

ARTICLE II
REPRESENTATIONS AND WARRANTIES OF NOVADIGM

Novadigm represents and warrants to Parent and Merger Sub, subject to the exceptions specifically disclosed in writing in the disclosure letter (referencing the applicable paragraph and section of this Article II) supplied by Novadigm to Parent on or prior to, and dated as of, the date hereof and certified by a duly authorized officer of Novadigm (the “Novadigm Disclosure Letter“), which Novadigm Disclosure Letter shall provide an exception to or otherwise qualify only the representations and warranties of Novadigm (i) contained in the paragraph of this Article II corresponding to such disclosure, and (ii) contained in any other paragraph of this Article II where the relevance of such exception or qualification is readily apparent from the face of such disclosure, as follows:

2.1 Organization; Standing and Power; Charter Documents; Subsidiaries.

(a) Organization; Standing and Power. Novadigm and each of its Subsidiaries (as defined below) is a corporation or other organization duly organized, validly existing and in good standing (with respect to any Subsidiary organized under the laws of any foreign jurisdiction, to the extent applicable in such jurisdiction), under the laws of the jurisdiction of its incorporation or organization, has the requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted and is duly qualified or licensed and in good standing to do business in each jurisdiction in which the nature of its business or the ownership or leasing of its properties makes such qualification necessary other than in such jurisdictions where the failure to so qualify or to be in good standing, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect (as defined in Section 8.3(b)) on Novadigm. For purposes of this Agreement, “Subsidiary,” when used with respect to any party, shall mean any corporation or other organization, whether incorporated or unincorporated, at least a majority of the securities or other interests of which having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such party or by any one or more of its subsidiaries, or by such party and one or more of its subsidiaries.

(b) Charter Documents. Novadigm has delivered or made available to Parent: (i) a true and correct copy of the Certificate of Incorporation (including any Certificate of Designations) and Bylaws of Novadigm, each as amended to date (collectively, the “Novadigm Charter Documents“) and (ii) the certificate of incorporation and bylaws, or like organizational documents (collectively, the “Subsidiary Charter Documents“), of each of its Subsidiaries, and each such instrument is in full force and effect. Novadigm is not in violation of any of the provisions of the Novadigm Charter Documents and no Subsidiary is in violation of any of its applicable Subsidiary Charter Documents.

(c) Subsidiaries. Section 2.1(c) of the Novadigm Disclosure Letter lists all of the Subsidiaries of Novadigm. All of the outstanding shares of capital stock of, or other equity or voting interests in, each such Subsidiary have been validly issued and are fully paid and nonassessable and are owned directly or indirectly by Novadigm, free and clear of all pledges, claims, liens, mortgages, charges, encumbrances, options and security interests of any kind or nature whatsoever (collectively, “Liens“), including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other ownership interests, except for restrictions imposed by applicable securities laws. Except for the capital stock of, or other equity or voting interests in, its Subsidiaries, Novadigm does not own,

directly or indirectly, any capital stock of, or other equity or voting interests in, any corporation, partnership, joint venture, association, limited liability company or other entity.

(d) Solvency. No bankruptcy, insolvency, judicial composition, voluntary arrangements with creditors or comparable proceedings have been initiated or applied for under any applicable law against Novadigm or any of its Subsidiaries.

2.2 Capital Structure.

(a) Capital Stock. The authorized capital stock of Novadigm consists of: (i) 30,000,000 shares of Novadigm Common Stock, par value $0.001 per share and (ii) 5,000,000 shares of preferred stock, par value $0.001 per share (the “Novadigm Preferred Stock“). At the close of business on January 30, 2004: (i) 19,178,385 shares of Novadigm Common Stock were issued and outstanding, (ii) no shares of Novadigm Common Stock were issued and held by Novadigm in its treasury, and (iii) no shares of Novadigm Preferred Stock were issued and outstanding. Between January 30, 2004 and the date of this Agreement, the Company has not issued any securities (including derivative securities) except for shares of Novadigm Common Stock issued upon exercise of stock options outstanding as of January 30, 2004 or purchase rights under the Novadigm Purchase Plan outstanding as of January 30, 2004. All of the outstanding shares of capital stock of Novadigm are, and all shares of capital stock of Novadigm which may be issued as contemplated or permitted by this Agreement will be, when issued, duly authorized and validly issued, fully paid and nonassessable and not subject to any preemptive rights. No shares of Novadigm Common Stock are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or any other agreement to which Novadigm or any of its Subsidiaries is a party.

(b) Stock Options. As of January 30, 2004: (i) an aggregate of 3,188,233 shares of Novadigm Common Stock, having a weighted average exercise price of $4.90 per share, were subject to issuance pursuant to outstanding options to purchase Novadigm Common Stock (together with the Replacement Options (as defined below), the “Novadigm Options“) under Novadigm’s 1992 Stock Option Plan, 1999 Nonstatutory Stock Option Plan and 2000 Stock Option Plan (collectively and including any Subplans thereunder, the “Novadigm Stock Plans“), and (ii) 326,807 shares of Novadigm Common Stock were reserved for future issuance under the 1995 Employee Stock Purchase Plan (the “Novadigm Purchase Plan“). Section 2.2(b) of the Novadigm Disclosure Letter sets forth a list of each outstanding Novadigm Option issued, and (a) the particular Novadigm

Stock Plan (if any) pursuant to which such Novadigm Option was granted, (b) the number of shares of Novadigm Common Stock subject to such outstanding Novadigm Option, (c) the exercise price of such Novadigm Option, (d) the date on which such Novadigm Option was granted, and (e) the extent to which such Novadigm Option was vested and exercisable as of January 30, 2004. All shares of Novadigm Common Stock subject to issuance under the Novadigm Stock Plans and the Novadigm Purchase Plan, upon issuance in accordance with the terms and conditions specified in the instruments pursuant to which they are issuable, would be duly authorized, validly issued, fully paid and nonassessable. There are no commitments or agreements of any character to which Novadigm is bound obligating Novadigm to (i) accelerate the vesting of any Novadigm Option as a result of the Merger (whether alone or upon the occurrence of any additional or subsequent events) or (ii) issue any Novadigm Options other than pursuant to the Option Exchange Program. No options to purchase Novadigm Common Stock or Novadigm Preferred Stock have been issued except pursuant to the Novadigm Stock Plans and the Novadigm Purchase Plan. There are no outstanding or authorized stock appreciation rights, phantom stock or other similar rights with respect to Novadigm.

As of their respective dates, each of the Novadigm SEC Documents was prepared in accordance and complied in all material respects with the requirements of the Securities Act of 1933, as amended (the “Securities Act“), and the Exchange Act, as applicable, and the rules and regulations of the SEC thereunder applicable to such Novadigm SEC Documents. None of the Novadigm SEC Documents, including any financial statements, schedules or exhibits included or incorporated by reference therein at the time they were filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except to the extent corrected prior to the date hereof by a subsequently filed Novadigm SEC Document. None of Novadigm’s Subsidiaries is required to file any forms, reports or other documents with the SEC.

(c) Undisclosed Liabilities. The balance sheet of Novadigm contained in the Novadigm SEC Documents as of September 30, 2003 is hereinafter referred to as the “Novadigm Balance Sheet.” Since the date of the Novadigm Balance Sheet, neither Novadigm nor any of its Subsidiaries has any material liabilities (absolute, accrued, contingent or otherwise) other than (i) any liabilities and obligations accrued for and reflected on the Novadigm Balance Sheet, (ii) any liabilities and obligations incurred since September 30, 2003 in the ordinary course of business consistent with past practice, and (iii) any obligations directly incurred pursuant to this Agreement or the Voting Agreements.

any joint venture, partnership agreement or any similar contract (including any contract relating to any transaction, arrangement or relationship between or among Novadigm or any of its Subsidiaries, on the one hand, and any unconsolidated affiliate, including any structured finance, special purpose or limited purpose entity or person, on the other hand) where the purpose or effect of such arrangement is to avoid disclosure of any material transaction involving Novadigm or any of its Subsidiaries in Novadigm’s consolidated financial statements, or is otherwise a party to any arrangement described in Section 303(a)(4) of Regulation S-K promulgated by the SEC.

(e) Sarbanes-Oxley Compliance. The chief executive officer and chief financial officer of Novadigm have made all certifications required by, and would be able to make such certifications as of the date hereof and as of the Closing Date as if required to be made as of such dates pursuant to, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act“) and any related rules and regulations promulgated by the SEC; the statements contained in any such certifications are complete and correct and have not been modified or withdrawn; and Novadigm is otherwise in compliance with all applicable effective provisions of the Sarbanes-Oxley Act and the applicable effective listing and corporate governance rules of The Nasdaq National Market. Neither Novadigm nor any of its officers has received notice from any Governmental Entity challenging or questioning the accuracy, completeness, form or manner of filing of the certifications required by the Sarbanes-Oxley Act and made by its chief executive officer and chief financial officer.

(f) Certifications. In the course of preparing the certifications described in Section 2.4(e) above, neither Novadigm nor any of its Subsidiaries nor any of their respective officers nor, to the knowledge of Novadigm, any employees became aware of any complaint, allegation, assertion or claim, whether written or oral, that, if true, could have resulted in the certifying officers having been unable to truthfully make such required certifications.

2.7 Intellectual Property.

(a) Section 2.7(a) of the Novadigm Disclosure Letter contains a complete and accurate list (by name and version number) of all products distributed, marketed, or sold by Novadigm or its Subsidiaries in the five (5) year period preceding the date hereof, and all products that are in development as of the date hereof and that Novadigm expects or intends to make available commercially or for revenue prior to twelve (12) months after the date hereof (“Novadigm Products”). As used herein, “Novadigm Services” refers to maintenance and support services and warranty services provided by Novadigm or its Subsidiaries in connection with the Novadigm Products, and professional consulting services provided by Novadigm or its Subsidiaries.

(b) Section 2.7(b) of the Novadigm Disclosure Letter sets forth all Registered Intellectual Property (as defined in Section 2.7(y)(iii))) owned by, filed in the name of, or applied for, by Novadigm or any of its Subsidiaries (“Novadigm Registered IP”). For patents and patent applications included in the Novadigm Registered IP, Section 2.7(b) of the Novadigm Disclosure Letter identifies the application, filing and registration number, registration and filing dates and the jurisdiction in which such registration or application is filed. For domain names included in the Novadigm Registered IP, Section 2.7(b) of the Novadigm Disclosure Letter identifies the jurisdiction in or for which each domain name was obtained, the named owner, and the registrar or equivalent Person with whom that domain name is registered.

(c) The Novadigm Registered IP is validly registered or filed in the name of Novadigm or any of its Subsidiaries in those countries identified in Section 2.7(b) of the Novadigm Disclosure Letter. For each item of Novadigm Registered IP, all necessary application, filing, registration, maintenance, renewal and other fees that are or have become due in connection therewith have been paid. To the knowledge of Novadigm and its Subsidiaries, there is no information that would render invalid or unenforceable any Novadigm Registered IP, or would

materially and adversely affect applications within the Novadigm Registered IP. Without limiting the foregoing, in relation to patents and patent applications within the Novadigm Registered IP, to the knowledge of Novadigm and its Subsidiaries, there is no information or fact (i) that would constitute prior art that has not previously been disclosed to the U.S. PTO (or corresponding agency in a non-U.S. jurisdiction) in connection with the application and prosecution of the relevant patent application, (ii) that would suggest an improper or incorrect designation of the inventor of the technology underlying such patent or patent application. To the knowledge of Novadigm and its Subsidiaries, there has been no inequitable conduct, or facts that would be a basis for a claim of inequitable conduct, in prosecution of the patents and patent applications within the Novadigm Registered IP. Neither Novadigm nor any of its Subsidiaries has misrepresented, or failed to disclose, or has knowledge of any misrepresentation or failure to disclose, any facts or circumstances in any application for any patents or patent applications within the Novadigm Registered IP that would constitute fraud or a knowing misrepresentation with respect to such application.

(d) In each case in which Novadigm or any of its Subsidiaries has obtained or acquired ownership of Registered Intellectual Property from another Person (i) with respect to patents, patent applications, or registered copyrights, Novadigm or any of its Subsidiaries has, where necessary, recorded or had recorded each such acquisition (including any assignment) with the relevant body, including the PTO, the U.S. Copyright Office, or their respective equivalents in the applicable jurisdiction, in each case in accordance with applicable laws and regulations, and (ii) with respect to domain names, Novadigm or any of its Subsidiaries has made or procured a formal transfer of the domain name in accordance with the procedure of the registrar for that jurisdiction.

(e) To the knowledge of Novadigm and its Subsidiaries, the operation of the business of Novadigm and each of its Subsidiaries, including the Novadigm Products and Novadigm Services and the development, marketing, distribution, sales and other exploitation of either of the foregoing, does not infringe or misappropriate in any respect the Intellectual Property (as defined in Section 2.7(y)(ii)) of any third party or constitute unfair competition or unfair trade practices under the laws of any applicable jurisdiction. Novadigm and its Subsidiaries own or possess sufficient rights to all Intellectual Property and Technology used in, incorporated in, distributed with, subsisting in or necessary for the use, distribution and other exploitation of any Novadigm Products or the provision of Novadigm Services, and all other Technology or Intellectual Property necessary for the operation of the businesses of Novadigm or any of its Subsidiaries. Without limiting the foregoing, Novadigm and its Subsidiaries have the right to use all software development tools, library functions, compilers and all other Third Party Technology that is (i) used to create, modify, compile, or

support any Novadigm Product, (ii) used to provide the Novadigm Services, or (ii) otherwise material to the operation of the businesses of Novadigm and its Subsidiaries.

(f) Neither Novadigm nor any of its Subsidiaries has received any written notice from any third party, and, to the knowledge of Novadigm and its Subsidiaries, there is no other assertion or pending threat from any third party, that the operation of the business of Novadigm or any of its Subsidiaries, the exploitation of any of the Novadigm Products or provision of the Novadigm Services by Novadigm or its Subsidiaries, infringes or misappropriates the Intellectual Property of any third party or constitutes unfair competition or unfair trade practices under the laws of any applicable jurisdiction. Neither Novadigm nor any of its Subsidiaries has brought or have been a party to any suits, arbitrations or other adversarial proceedings with respect to a third party’s Intellectual Property that remain pending. No litigation is pending, or to the knowledge of Novadigm or its Subsidiaries is threatened, relating to the use, validity or ownership of the Intellectual Property owned or used by Novadigm or any of its Subsidiaries.

(g) To the knowledge of Novadigm or its Subsidiaries, no Person is infringing or misappropriating any Intellectual Property owned or exclusively licensed by Novadigm or any of its Subsidiaries. Neither Novadigm nor any of its Subsidiaries has brought or has been a party to any suits, arbitrations or other adversarial proceedings with respect to their Intellectual Property against any third party that remain pending.

(h) Novadigm and its Subsidiaries are not subject to any judgment, order, writ, injunction or decree of any court or any Federal, state, local, foreign or other governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, or any arbitrator, which restricts or impairs the use of any of their Intellectual Property. The Intellectual Property owned or exclusively licensed by Novadigm or its Subsidiaries is free and clear of any Liens other than licenses. No compulsory licenses or licenses of right have been, or to the knowledge of Novadigm or its Subsidiaries are reasonably likely to be, granted in respect of the Intellectual Property owned by Novadigm or any of its Subsidiaries.

(i) Neither Novadigm nor any of its Subsidiaries has granted any exclusive license of or exclusive right to, or authorized the retention of any exclusive rights to, any Intellectual Property or Technology that is owned by Novadigm or any of its Subsidiaries, except for such licenses or rights that are no longer in effect. During the twelve (12) months prior to the date hereof, neither Novadigm nor any of its Subsidiaries has transferred ownership of any

Intellectual Property or Technology of Novadigm or any of its Subsidiaries that is within the Novadigm Products or necessary for providing maintenance and support services with respect to the Novadigm Products. Without limiting the foregoing, no Person who has licensed Technology or Intellectual Property to Novadigm or any of its Subsidiaries has ownership or license rights to improvements made by Novadigm or any of its Subsidiaries to such Technology or Intellectual Property, other than with respect to use of such Technology or Intellectual Property in identified deliverables provided only to that Person. There is no Technology or Intellectual Property incorporated into, combined with, or distributed in conjunction with a Novadigm Product for which another Person is the sole or joint owner, or the owner of any portion thereof.

(j) Novadigm and each of its Subsidiaries are not in material breach of any material term of, and are otherwise in compliance with, any contracts, licenses or other agreements to which Novadigm or any of its Subsidiaries is bound in which Novadigm and its Subsidiaries have granted or received any Intellectual Property or Technology (“Novadigm IP Agreements”). To the knowledge of Novadigm, all third parties to such Novadigm IP Agreements are in compliance with, and have not materially breached, any of their terms. To Novadigm’s knowledge, there are no disputes regarding the scope of the Novadigm IP Agreements, performance under Novadigm IP Agreements, or with respect to payments made or received under the Novadigm IP Agreements.

(k) The Merger will not give rise to or cause a right of termination under, or a breach of, or any loss or change in the rights or obligations of Novadigm or its Subsidiaries under, any Novadigm IP Agreements pursuant to the terms of such Novadigm IP Agreements. The Merger will not give rise to Novadigm or its Subsidiaries being, or cause Novadigm or its Subsidiaries to be, legally obligated to pay any consideration, royalties or other amounts to any third party in excess of those amounts otherwise owed by Novadigm or its Subsidiaries immediately prior to the Merger.

(l) The Merger will not (a) give rise to Parent or its Subsidiaries being bound by, or cause Parent or its Subsidiaries to be bound by, any non-solicitation, non-compete, exclusivity obligation or other material restriction on the operation of any business of Novadigm or its Subsidiaries, including exploitation of the any of their products or services, or (b) give rise to a grant by, or cause Parent or its Subsidiaries (other than Surviving Corporation, but only to the extent existing prior to the Merger) to grant, to any third party any rights or licenses to any Intellectual Property or Technology of Parent or any affiliate of Parent (including without limitation a covenant not to sue) pursuant to any agreements or obligations of Novadigm or its Subsidiaries.

(m) All former and current employees, consultants and independent contractors of Novadigm or any of its Subsidiaries who were or are key personnel, who were or are members of Novadigm’s management or who have been involved with the conception and development of Intellectual Property or Technology owned by Novadigm or any of its Subsidiaries, have assigned or otherwise transferred to Novadigm all ownership and other rights of any nature whatsoever (to the extent permitted by law) of such person in any Intellectual Property or Technology developed for Novadigm or developed in the course and scope of such person’s relationship with Novadigm. To the knowledge of Novadigm and its Subsidiaries, none of the former and current employees, agents, consultants and independent contractors of Novadigm or any of its Subsidiaries who were or are key personnel, who were or are members of Novadigm’s management or who have been involved with the conception and development of Intellectual Property or Technology owned by Novadigm or any of its Subsidiaries, have a valid claim against Novadigm or any of its Subsidiaries in connection with any Intellectual Property or Technology owned by Novadigm or any of its Subsidiaries, and no such claim has been asserted or, to the knowledge of Novadigm, threatened.

(n) The execution and delivery of this Agreement, the consummation of the transactions contemplated by this Agreement, the compliance with the provisions of this Agreement and the Merger do not and will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time or both) relating to, or give rise to any right, license or encumbrance relating to, any Intellectual Property or Technology owned or licensed by Novadigm or any of its Subsidiaries or with respect to which Novadigm or any of its Subsidiaries now has any agreement with any third party, or any right of termination, cancellation or acceleration of any Intellectual Property right or right in relation to Technology or obligation set forth in any agreement to which Novadigm or any of its Subsidiaries is a party, or the loss or encumbrance of any Intellectual Property or benefit related thereto, or result in the creation of any Lien in or upon any Intellectual Property or Technology or right, except with respect to those Contracts which by their terms or nature are not transferable to Parent in connection with the transactions contemplated by this Agreement, which are set forth in Section 2.3(b) of the Novadigm Disclosure Letter.

(o) To the extent Third Party Technology (as defined below) is distributed to customers of Novadigm or any of its Subsidiaries together with the Technology of Novadigm or any of its Subsidiaries (including as part of the Novadigm Products), (x) the third party rights and the Novadigm IP Agreements under which those rights have been obtained have been identified in Section 2.7(o) of the Novadigm Disclosure Letter, (y) all necessary licenses have been

obtained by Novadigm and its Subsidiaries, and (z) no royalties or payments in excess of $50,000, either individually or in the aggregate, are due. For purposes of this Agreement, “Third Party Technology” shall mean Technology, including software (including object code, source code, and associated data and documentation), with respect to which a third party holds any copyright or other ownership right (and, therefore, such software is not owned exclusively by Novadigm or any of its Subsidiaries). To the extent Novadigm or its Subsidiaries are licensees of material Intellectual Property Rights, (i) the third party Intellectual Property Rights and the Novadigm IP Agreements under which those Intellectual Property Rights have been obtained are identified on Section 2.7(o) of the Novadigm Disclosure Letter, and (ii) no royalties or payments in excess of $50,000, either individually or in the aggregate, are due.

(p) None of the Technology of Novadigm or any of its Subsidiaries that is protected as a trade secret (including any software source code in the Novadigm Products) has been published or disclosed by Novadigm or any of its Subsidiaries, except pursuant to a non-disclosure agreement that is substantively similar to the standard form used by Novadigm that has been provided to Parent prior to the date of this Agreement, or, to the knowledge of Novadigm or any of its Subsidiaries, published or disclosed by any other Person to any Person, except pursuant to licenses or Contracts requiring such other Persons to keep such trade secrets confidential. To the extent that the foregoing disclosed trade secrets are source code of Novadigm or its Subsidiaries, it has been disclosed only under a binding agreement with an escrow agent. No event has occurred that is designated as a condition triggering release of source code to a third party under an escrow agreement under which Novadigm or a Subsidiary is obliged to escrow or has escrowed source code for Novadigm Products. The execution of this Agreement and the Merger will not trigger release of source code to a third party under an escrow agreement under which Novadigm or a Subsidiary is obliged to escrow or has escrowed source code for Novadigm Products.

(q) No licenses or rights have been granted by Novadigm or any of its Subsidiaries to a third party to distribute, sell or use (including use to create Derivative Works (as defined in Section 2.7(y)(i))) the source code of, any Novadigm Product currently marketed by, commercially available from or under development by Novadigm or any of its Subsidiaries for which Novadigm or any of its Subsidiaries possesses the source code, except with respect to source code escrow arrangements entered into by Novadigm or any of its Subsidiaries with its customers for which the source code in escrow has not been released or disclosed to the licensee thereof, and which arrangements are set forth in Section 2.7(q) of the Novadigm Disclosure Letter.

(r) Novadigm and each of its Subsidiaries has taken all reasonable steps to protect Intellectual Property and Technology owned by Novadigm or its Subsidiaries and their rights thereunder, and to the knowledge of Novadigm no such rights to any such Intellectual Property or Technology have been lost or are currently at risk of being lost through prior or current failures to act by Novadigm or any of its Subsidiaries. Without limiting the foregoing, Novadigm and its Subsidiaries have, and enforce, a policy requiring each employee, consultant or contractor to execute a proprietary information, confidentiality and assignment agreement substantially in Novadigm’s standard form previously provided to Parent.

(s) Novadigm and its Subsidiaries do not have any commitment to license any Intellectual Property of Novadigm or its Subsidiaries to any standards body, to any Person by virtue of such Person being a member of a standards body, or to any Person by virtue of such Person having implemented a standard administered or promulgated by a standards body. The Novadigm Products are not required to be compliant with any standards promulgated or administered by a third party pursuant to a contractual commitment with such third party.

(t) Novadigm has not granted or agreed to grant any exclusive rights or licenses with respect to the Novadigm Products, or to distribution, marketing, selling, providing or otherwise exploiting the Novadigm Products, including exclusive distribution or reseller arrangements, nor has any Subsidiary of Novadigm granted or agreed to grant such rights, except in any case for any such rights or licenses that are no longer in effect.

(u) Novadigm (or any Subsidiary of Novadigm) does not have any warranty obligations with respect to the Novadigm Products that are in effect as of the date of this Agreement and that materially deviate from the standard warranties Novadigm provides with respect to such Novadigm Products, a copy of which warranties are included in Section 2.7(u) of the Novadigm Disclosure Letter (“Standard Product Warranties”). For purposes of this Section 2.7(u), warranties will be deemed to “materially deviate” from the Standard Product Warranties if (i) the terms of Novadigm or its Subsidiaries’ agreement with the third parties includes substantive warranties in addition to, or materially different than, the Standard Product Warranties; (ii) with respect to warranties regarding performance of a Novadigm Product, the warranty is for a period longer than twelve (12) months after termination of support and maintenance for that Novadigm Product pursuant to Novadigm’s standard terms and conditions for support and maintenance, (iii) with respect to warranties regarding performance of a Novadigm Product, the terms provide for a refund or otherwise provide for a remedy other than repair and replacement of the product, and (iv) with respect to

warranties regarding infringement by the Novadigm Product (including rights to grant the licenses granted), the terms provide for a remedy other than defense and settlement of third party claims and termination and refund if the infringement cannot be cured by obtaining a license or replacing or modifying the Novadigm Product. During the twelve (12) months prior to the date of this Agreement, neither Novadigm, its Subsidiaries, nor, to Novadigm’s knowledge its agents or distributors, have received any warranty claims related to the Novadigm Products. To the knowledge of Novadigm and its Subsidiaries, there exist no grounds for a credible warranty claim regarding the Novadigm Products, other than a warranty claim for which the sole remedy is provision of maintenance and support. To the knowledge of Novadigm and its Subsidiaries, there are no unresolved security holes or vulnerabilities in the Novadigm Products that would permit unauthorized or unknown access to computers or systems of users through those Novadigm Products, and Novadigm and its Subsidiaries have taken reasonable steps and implemented reasonable procedures (based on standard industry practices) to ensure that the Novadigm Products are free from viruses and other disabling codes. Novadigm has provided to Parent a list of all open trouble tickets reported by Novadigm’s customers to Novadigm’s support team, and a list of all open trouble tickets reported by Novadigm’s internal staff, which trouble tickets include reported issues such as usage issues, configuration or documentation-related questions and potential bugs or non-conformities. It is Novadigm’s practice to document reported problems or issues with respect to the Novadigm Products on a trouble ticket.

(v) Section 2.7(v) of the Novadigm Disclosure Letter lists all software or other material that is distributed as “free software,” “open source software” or under a similar licensing or distribution model (including but not limited to the GNU General Public License) that is incorporated into, combined with, or distributed in conjunction with a Novadigm Product (“Open Source Materials”). Section 2.7(v) of the Novadigm Disclosure Letter further identifies each of the Open Source Materials that are licensed under terms that in some circumstances grant, purport to grant to the licensor or any other Person any rights to the Technology or Intellectual Property of the licensee, or that require other Software incorporated into, derived from or distributed with such Open Source Materials (i) be disclosed or distributed in source code form, (ii) be licensed for the purpose of making derivative works, or (iii) be redistributable at no charge. The Open Source Materials are not utilized by Novadigm or its Subsidiaries in connection with a Novadigm Product in a manner that creates obligations for Novadigm or any of its Subsidiaries with respect to their own Intellectual Property or Technology under the license terms for the applicable Open Source Materials, including but not limited to any obligation that Technology or Intellectual Property owned by Novadigm or its Subsidiaries (i) be disclosed or

distributed in source code form, (ii) be licensed for the purpose of making derivative works, or (iii) be redistributable at no charge.

(w) No government funding, facilities of a university, college, other educational institution or research center was used in the development of any Intellectual Property or Technology owned by Novadigm or its Subsidiaries and incorporated in, distributed with, subsisting in or necessary for the use, distribution and other exploitation of any Novadigm Product.

(x) Other than a restriction requiring a notice period of six (6) months or less, there is no restriction on the right of Novadigm or any of its Subsidiaries to discontinue offering any Novadigm Product or to discontinue offering maintenance and support for any Novadigm Product, without regard for whether a new version of a Novadigm Product is available at the time of discontinuance.

(g) Effect of Transaction.

(i) The execution of this Agreement and the consummation of the transactions contemplated hereby will not (either alone or upon the occurrence of an individual’s termination of employment within one year prior to or three years following the transactions contemplated hereby), constitute an event under any Novadigm Employee Plan, Novadigm Employee Agreement, trust or loan that will, or would reasonably be expected to, result in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any Novadigm Employee.

(ii) There is no agreement, plan, arrangement or other contract covering any Novadigm Employee that, considered individually or considered collectively with any other such agreements, plans, arrangements or other contracts, will, or would reasonably be expected to, give rise directly or indirectly to the payment of any amount that would be characterized as a “parachute payment” within the meaning of Section 280G(b)(2) of the Code.

There are no claims or actions against Novadigm or any Novadigm ERISA Affiliate under any worker’s compensation policy or long-term disability policy. Neither Novadigm nor any Novadigm ERISA Affiliate has or reasonably anticipates any direct or indirect material liability with respect to any misclassification of any person as an independent contractor rather than as an employee, or with respect to any employee leased from another employer.

(i) Labor. No work stoppage or labor strike against Novadigm or any Novadigm ERISA Affiliate is pending or, to Novadigm’s knowledge, threatened or reasonably anticipated. None of the Novadigm Employees are represented by a labor union, works council or trade union and, to the knowledge

of Novadigm and its Subsidiaries, there are no activities or proceedings of any labor union, trade union or works council to organize any Novadigm Employees. There are no actions, suits, claims, labor disputes or grievances pending, or, to the knowledge of Novadigm or any Novadigm ERISA Affiliate, threatened relating to any labor, safety or discrimination matters involving any Novadigm Employee, including, without limitation, charges of unfair labor practices or discrimination complaints, which, if adversely determined, would, individually or in the aggregate, result in any material liability to Novadigm. Neither Novadigm nor any of its Subsidiaries has engaged in any unfair labor practices within the meaning of the National Labor Relations Act. Neither Novadigm nor any Novadigm ERISA Affiliate is presently, or has been in the past, a party to, or bound by, any collective bargaining agreement, union contract or similar agreement with respect to Novadigm Employees and no collective bargaining agreement is being negotiated with respect to Novadigm Employees. Neither Novadigm nor any of its Subsidiaries has incurred any material liability or material obligation under the Worker Adjustment and Retraining Notification Act or any similar state or local law which remains unsatisfied.

Each Novadigm Employee Plan that has been adopted or maintained by Novadigm or any Novadigm ERISA Affiliate, whether informally or formally, or with respect to which Novadigm or any Novadigm ERISA Affiliate will have any liability, for the benefit of Novadigm Employees who perform services outside the United States (each a “Novadigm International Employee Plan“) has been established, maintained and administered in material compliance with its terms and conditions and with the requirements prescribed by any and all statutory or regulatory laws that are applicable to such Novadigm International Employee Plan. No Novadigm International Employee Plan is a defined benefit pension plan. Furthermore, no Novadigm International Employee Plan has unfunded liabilities, that as of the Effective Time, will not be offset by insurance or fully accrued. Except as required by law, no condition exists that would prevent Novadigm or Parent from terminating or amending any Novadigm International Employee Plan at any time for any reason without liability to Novadigm or its Novadigm ERISA Affiliates (other than ordinary administration expenses or routine claims for benefits).

All such current leases are in full force and effect in accordance with their respective terms, and there is not, under any of such leases, any existing material default or material event of default (or event that with notice or lapse of time, or both, would constitute a material default) by Novadigm or one of its Subsidiaries or, to the knowledge of Novadigm, by any other party thereto.

(b) Board Recommendation. Except to the extent expressly permitted by Section 5.3(d): (i) the Board of Directors of Novadigm shall unanimously recommend that the stockholders of Novadigm vote in favor of

adoption and approval of this Agreement and approval of the Merger, at the Stockholders’ Meeting, (ii) the Proxy Statement shall include a statement to the effect that the Board of Directors of Novadigm has unanimously recommended that Novadigm’s stockholders vote in favor of adoption and approval of this Agreement and approval of the Merger at the Stockholders’ Meeting, and (iii) neither the Board of Directors of Novadigm nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to Parent, the Novadigm Board Recommendation.

5.3 Acquisition Proposals.

(a) No Solicitation. Novadigm agrees (a) that Novadigm and each of its Subsidiaries, and the officers and directors of Novadigm and each of its Subsidiaries and any investment banker, attorney or accountant retained by Novadigm or any of its Subsidiaries, shall not, directly or indirectly, and (b) that Novadigm shall not authorize or knowingly permit, and shall use its reasonable best efforts to cause, its employees and any other agents and representatives of Novadigm or its Subsidiaries not to, directly or indirectly: (i) solicit, initiate, encourage, or knowingly facilitate or induce any inquiry with respect to, or the making, submission or announcement of, any Acquisition Proposal (as defined in Section 5.3(g)), (ii) participate in any discussions (except to confirm the existence of the restrictions set forth in this Section 5.3) or negotiations regarding, or furnish to any Person any information with respect to, or take any other action intended to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any Acquisition Proposal, (iii) approve, endorse or recommend any Acquisition Proposal (except to the extent specifically permitted pursuant to Section 5.3(d)), or (iv) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any Acquisition Proposal or transaction contemplated thereby. Novadigm and each of its Subsidiaries and each of the officers, directors, employees, agents and representatives (including any investment banker, attorney or accountant retained by Novadigm or any of its Subsidiaries) of Novadigm or any of its Subsidiaries have complied with the terms of the letter agreement, dated December 16, 2003, by and between Parent and Novadigm (the “Letter Agreement”), and will each immediately cease any and all existing activities, discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal. Without limiting the generality of the foregoing, it is understood that any violation of the restrictions set forth in this Section 5.3(a) by any officer or director of Novadigm or its Subsidiaries or any investment banker, attorney or accountant retained by Novadigm or any of its Subsidiaries shall be deemed to be a breach of this Section 5.3(a) by Novadigm.

(b) Notification of Unsolicited Acquisition Proposals. As promptly as reasonably practicable (and, in any event, within 24 hours) after receipt of any Acquisition Proposal or any request for nonpublic information or inquiry which it reasonably believes could lead to an Acquisition Proposal, Novadigm shall provide Parent with oral and written notice of the material terms and conditions of such Acquisition Proposal, request or inquiry, and the identity of the Person or group making any such Acquisition Proposal, request or inquiry and a copy of all written materials provided in connection with such Acquisition Proposal, request or inquiry. Novadigm shall provide Parent as promptly as reasonably practicable (and, in any event within 24 hours) oral and written notice setting forth all such information as is reasonably necessary to keep Parent informed in all material respects of the status and details (including material amendments or proposed material amendments) of any such Acquisition Proposal, request or inquiry and a copy of all written materials subsequently provided to or by Novadigm in connection with such Acquisition Proposal, request or inquiry.

(c) Superior Offers. Notwithstanding anything to the contrary contained in Section 5.3(a), in the event that Novadigm receives an unsolicited, bona fide written Acquisition Proposal from a third party that did not otherwise result from a breach of this Section 5.3 or the Letter Agreement and its Board of Directors has in good faith concluded (following consultation with its financial advisor) that such Acquisition Proposal is, or could reasonably be expected to result in, a Superior Offer (as defined in Section 5.3(g)), it may then take the following actions (but only if and to the extent that its Board of Directors concludes in good faith, following consultation with its outside legal counsel, that the failure to do so would result in a breach of its fiduciary obligations under applicable law) for so long as none of the conclusions referenced above changes:

(i) Furnish information to the third party making such Acquisition Proposal, provided that (A) (1) one business day prior to furnishing any such nonpublic information to such party, Novadigm gives Parent written notice of its intention to furnish nonpublic information and (2) Novadigm receives from the third party an executed confidentiality agreement, the terms of which are no less favorable to Novadigm than the terms contained in the Confidentiality Agreement (as defined in Section 5.4(a)) and (B) contemporaneously with furnishing any such nonpublic information to such third party, Novadigm furnishes a list of such nonpublic information provided to such third party and, to the extent such nonpublic information has not been previously furnished to Parent, copies of such nonpublic information; and

(ii) Engage in discussions or negotiations with the third party with respect to the Acquisition Proposal, provided that one business day prior to entering into discussions or negotiations with such third party, Novadigm

gives Parent written notice of the intention to enter into discussions or negotiations with such third party.

(d) Changes of Recommendation. In response to the receipt of a Superior Offer, the Board of Directors of Novadigm may withhold, withdraw, amend or modify the Novadigm Board Recommendation, and, in the case of a Superior Offer that is a tender or exchange offer made directly to its stockholders, may recommend that its stockholders accept the tender or exchange offer (any of the foregoing actions, whether by the Board of Directors or a committee thereof, together with any other public statement that makes it reasonably apparent that the Board of Directors or a committee thereof desires to take any of the following actions, a “Change of Recommendation”), if all of the following conditions in clauses (i) through (v) are met:

(i) The Board of Directors determines, in good faith, that the Acquisition Proposal constitutes a Superior Offer and such Superior Offer has been made and has not been withdrawn;

(ii) Novadigm’s Stockholders’ Meeting has not occurred;

(iii) (A) Novadigm shall have delivered to Parent written notice (a “Change of Recommendation Notice”) at least four (4) business days prior to effecting such Change of Recommendation, which notice shall state expressly (1) that it has received an Acquisition Proposal which it has determined is a Superior Offer and (2) that it intends to effect a Change of Recommendation and the manner in which it intends or may intend to do so; and (B) Novadigm and its Board of Directors shall have complied with all obligations under Sections 5.3(a), (b), and (c) of this Agreement;

(iv) Novadigm’s Board of Directors has concluded in good faith, after consultation with its outside legal counsel, that, in light of such Superior Offer, the failure of the Board of Directors to effect a Change of Recommendation would result in a breach of its fiduciary obligations to its stockholders under applicable law; and

(v) Novadigm shall not have breached any of the provisions set forth in Section 5.2 or this Section 5.3 or the Letter Agreement.

In the event that Novadigm delivers to Parent a Change of Recommendation Notice, Novadigm and the Board of Directors of Novadigm shall provide Parent the opportunity to make a counter-proposal to such Superior Offer, and shall consider in good faith and cause its financial and legal advisors to

negotiate on its behalf in good faith with respect to the terms of such counter-proposal.

(e) Continuing Obligation to Call, Hold and Convene Stockholders’ Meeting; No Other Vote. Notwithstanding anything to the contrary contained in this Agreement, the obligation of Novadigm to call, give notice of, convene and hold its Stockholders’ Meeting shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission to it of any Acquisition Proposal with respect to it, or by any Change of Recommendation. Novadigm shall not submit to the vote of its respective stockholders any Acquisition Proposal, or propose to do so.

(f) Compliance with Tender Offer Rules. Nothing contained in this Agreement shall prohibit Novadigm or its Board of Directors from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided that the content of any such disclosure thereunder shall be governed by the terms of this Agreement. Without limiting the foregoing proviso, Novadigm shall not effect a Change of Recommendation unless specifically permitted pursuant to the terms of Section 5.3(d). Nothing contained in this Section 5.3(f) shall be interpreted to affect or otherwise qualify, limit or modify in any way the definition of “Triggering Event” set forth in Section 7.1(g) hereof.

(g) Certain Definitions. For purposes of this Agreement, the following terms shall have the following meanings:

(i) “Acquisition Proposal” shall mean any offer or proposal, relating to any transaction or series of related transactions involving: (A) any purchase from such party or acquisition by any Person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a fifteen percent (15%) interest in the total outstanding voting securities of Novadigm or any of its Subsidiaries or any tender offer or exchange offer that if consummated would result in any person or group beneficially owning fifteen percent (15%) or more of the total outstanding voting securities of Novadigm or any of its Subsidiaries or any merger, consolidation, business combination or similar transaction involving Novadigm or any of its Subsidiaries, (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition or disposition of assets of Novadigm (including its Subsidiaries taken as a whole) representing more than fifteen percent (15%) of the aggregate fair market value of Novadigm’s business immediately prior to such acquisition, or (C) any liquidation or dissolution (or the adoption of a plan pertaining thereto) of Novadigm or the declaration or payment of an extraordinary dividend (whether in

cash or other property); provided, however, that the Merger and the transactions contemplated hereby shall not be deemed an Acquisition Proposal in any case; and

(ii) “Superior Offer,” with respect to Novadigm, shall mean an unsolicited, bona fide written offer made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination, all or substantially all of the assets of Novadigm or a majority of the total outstanding voting securities of Novadigm, on terms that Novadigm’s Board of Directors has in good faith concluded (following consultation with its outside legal counsel and its financial adviser), taking into account, among other things, legal, financial, regulatory and other aspects of the offer and the Person making the offer and any changes to the terms of this Agreement proposed by Parent in response to such offer or otherwise, to (A) be more favorable from a financial point of view to Novadigm’s stockholders (in their capacities as stockholders) than the terms of the Merger, (B) be reasonably capable of being consummated and (C) not be subject to a due diligence or financing condition to closing.

5.4 Confidentiality; Access to Information; No Modification of Representations, Warranties or Covenants.

(a) Confidentiality. The parties acknowledge that Novadigm and Parent have previously executed a Mutual Nondisclosure Agreement dated December 16, 2003 (the “Confidentiality Agreement”), which Confidentiality Agreement will continue in full force and effect in accordance with its terms.

(b) Access to Information. Upon reasonable prior notice and subject to the Confidentiality Agreement, Novadigm will afford Parent and Parent’s accountants, counsel and other representatives reasonable access during normal business hours to its properties, books, records and personnel (including, without limitation, all persons involved in preparation of Novadigm’s financial statements, internal controls, disclosure controls and procedures and financial reporting processes) during the period prior to the Effective Time in a manner that does not unreasonably disrupt Novadigm’s business to obtain all information concerning its business, including the status of product development efforts, properties, results of operations and personnel, as such other party may reasonably request, and, during such period, upon request Novadigm shall, and shall cause each of its Subsidiaries to, furnish promptly to Parent a copy of any report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of federal or state securities laws; provided, however, that Novadigm may restrict the foregoing access to the extent that any law, treaty, rule or regulation of any Governmental Entity applicable to such party

requires Novadigm or its Subsidiaries to restrict or prohibit access to any such properties or information.

(c) No Modification of Representations and Warranties or Covenants. No information or knowledge obtained in any investigation or notification pursuant to this Section 5.4, Section 5.6 or Section 5.7 shall affect or be deemed to modify any representation or warranty contained herein, the covenants or agreements of the parties hereto or the conditions to the obligations of the parties hereto under this Agreement.

5.5 Public Disclosure. Parent and Novadigm shall consult with each other before issuing any press release or making any public statement with respect to the Merger or this Agreement and shall not issue any such press release or make any such public statement without the prior written consent of the other party, which shall not be unreasonably withheld or delayed; provided, however, that a party may, without the prior consent of the other party, issue such press release or make such public statement as such party determines in good faith, following consultation with legal counsel, may be required by law or the rules and regulations of the NYSE or The Nasdaq National Market if it has used all reasonable efforts to consult with the other party prior thereto and provided, further, that, following a Change of Recommendation, no such consent shall be required.

5.6 Regulatory Filings; Reasonable Efforts.

(a) Regulatory Filings. Subject to the requirements set forth in Section 5.1 applicable to the Proxy Statement, each of Parent, Merger Sub and Novadigm shall coordinate and cooperate with one another and shall each use commercially reasonable efforts to comply with, and shall each refrain from taking any action that would impede compliance with, all Legal Requirements, and as promptly as practicable after the date hereof, each of Parent, Merger Sub and Novadigm shall make all filings, notices, petitions, statements, registrations, submissions of information, application or submission of other documents required by any Governmental Entity in connection with the Merger and the transactions contemplated hereby, including, without limitation: (i) Notification and Report Forms with the United States Federal Trade Commission (the “FTC”) and the Antitrust Division of the United States Department of Justice (“DOJ”) as required by the HSR Act, (ii) any other filing necessary to obtain any Necessary Consent, (iii) filings under any other comparable pre-merger notification forms required by the merger notification or control laws of any applicable jurisdiction, as agreed by the parties hereto, and (iv) any filings required under the Securities Act, the Exchange Act, any applicable state or securities or “blue sky” laws and the securities laws of any foreign country, or any other Legal Requirement

relating to the Merger. Each of Parent and Novadigm will cause all documents that it is responsible for filing with any Governmental Entity under this Section 5.6(a) to comply in all material respects with all applicable Legal Requirements.

(b) Exchange of Information. Parent, Merger Sub and Novadigm each shall promptly supply the other, or their counsel, with such appropriate information that is necessary in order to effectuate any filings or application pursuant to Section 5.6(a). Except where prohibited by applicable Legal Requirements, and subject to the Confidentiality Agreement, each of Novadigm and

Parent shall consult with the other prior to taking a position with respect to any such filing, shall permit the other to review and discuss in advance, and consider in good faith the views of the other in connection with any analyses, appearances, presentations, memoranda, briefs, white papers, arguments, opinions and proposals before making or submitting any of the foregoing to any Governmental Entity by or on behalf of any party hereto in connection with any investigations or proceedings in connection with this Agreement or the transactions contemplated hereby (including under any antitrust or fair trade Legal Requirement), coordinate with the other in preparing and exchanging such information and promptly provide the other (and its counsel) with copies of all filings, presentations or submissions (and a summary of any oral presentations) made by such party with any Governmental Entity in connection with this Agreement or the transactions contemplated hereby, provided that with respect to any such filing, presentation or submission, each of Parent and Novadigm need not supply the other (or its counsel) with copies (or in case of oral presentations, a summary) to the extent that any law, treaty, rule or regulation of any Governmental Entity applicable to such party requires such party or its Subsidiaries to restrict or prohibit access to any such properties or information. It is acknowledged and agreed by the parties hereto that, except where prohibited by applicable Legal Requirements, Parent and Novadigm shall mutually consult with each other on the strategy for dealing with the FTC, DOJ, the European Commission or any other Governmental Entity with responsibility for reviewing the Merger with respect to antitrust or competition issues; provided, however, in the event Parent and Novadigm differ upon such strategy following such consultation, Parent’s strategy shall prevail and be cooperated with by Novadigm.

(c) Notification. Each of Parent, Merger Sub and Novadigm will notify the other promptly upon the receipt of: (i) any comments from any officials of any Governmental Entity in connection with any filings made pursuant hereto and (ii) any request by any officials of any Governmental Entity for amendments or supplements to any filings made pursuant to, or information provided to comply in all material respects with, any Legal Requirements. Whenever any event occurs that is required to be set forth in an amendment or

supplement to any filing made pursuant to Section 5.6(a), Parent, Merger Sub or Novadigm, as the case may be, will promptly inform the other of such occurrence and cooperate in filing with the applicable Governmental Entity such amendment or supplement.

(d) Reasonable Efforts. Subject to the express provisions of Section 5.2 and Section 5.3 hereof and upon the terms and subject to the conditions set forth herein, each of the parties agrees to use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including using commercially reasonable efforts to accomplish the following: (i) causing the conditions precedent set forth in Article VI to be satisfied, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from Governmental Entities and the making of all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any) and the taking of all commercially reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity, (iii) the obtaining of all necessary consents, approvals or waivers from third parties, including all Necessary Consents, and the removal of all Legal Restraints, (iv) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, (v) the execution or delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement, and (vi) in the case of Parent, voting the shares of Novadigm Common Stock held by Parent in favor of approval and adoption of this Agreement and approval of the Merger. In connection with and without limiting the foregoing, Novadigm, its Board of Directors and Subsidiaries shall, if any takeover statute or similar Legal Requirement is or becomes applicable to the Merger, this Agreement or any of the transactions contemplated by this Agreement, use all commercially reasonable efforts to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such Legal Requirement on the Merger, this Agreement and the transactions contemplated hereby.

(e) Limitation on Divestiture. Notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall be

deemed to require Parent or any Subsidiary or affiliate thereof to take or agree to take any Action of Divestiture (as defined below). For purposes of this Agreement, an “Action of Divestiture” shall mean making proposals, executing or carrying out agreements or submitting to Legal Requirements providing for the license, sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets that are material to Parent, Novadigm or any of their respective Subsidiaries or the holding separate of Novadigm capital stock or imposing or seeking to impose any limitation on the ability of Parent, Novadigm or any of their respective Subsidiaries, to conduct their respective businesses or own such assets or to acquire, hold or exercise full rights of ownership of Novadigm’s business.

5.7 Notification of Certain Matters.

(a) By Novadigm. Novadigm shall give prompt notice to Parent and Merger Sub of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate in any material respect, or any failure of Novadigm to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement.

(b) By Parent. Parent and Merger Sub shall give prompt notice to Novadigm of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate in any material respect, or any failure of Parent to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement.

5.8 Third-Party Consents. As soon as practicable following the date hereof, Novadigm and Parent will use all reasonable efforts to obtain any consents, waivers and approvals under any of its or its Subsidiaries’ respective Contracts required to be obtained in connection with the consummation of the transactions contemplated hereby.

5.9 Equity Awards and Employee Benefits.

(a) Assumption of Novadigm Options Held by Current Novadigm Employees. At the Effective Time, each then outstanding Novadigm Option held by a Novadigm Employee who is employed by Novadigm or one of its Subsidiaries immediately prior to the Effective Time and becomes employed by Parent or one of its Subsidiaries immediately after the Effective Time, whether or not exercisable at the Effective Time and regardless of the respective exercise prices thereof, will be assumed by Parent. Each Novadigm Option so assumed by Parent under this Agreement will continue to have, and be subject to, the same

terms and conditions set forth in the applicable Novadigm Option (including any applicable stock option agreement, Novadigm Stock Plan or other document evidencing such Novadigm Option) immediately prior to the Effective Time (including any repurchase rights or vesting provisions), except that (i) each Novadigm Option will be exercisable (or will become exercisable in accordance with its terms) for (x) that number of shares of Parent common stock, par value $0.01 per share (“Parent Common Stock”) (rounded down to the nearest whole share) determined by multiplying the number of shares of Novadigm Common Stock subject to such Novadigm Option by a fraction (the “Option Exchange Ratio”), the numerator of which is the Merger Consideration and the denominator of which is the average closing price of Parent Common Stock on the New York Stock Exchange Composite Transactions Tape on the ten trading days immediately preceding the date on which the Effective Time occurs at (y) an exercise price per share of Parent Common Stock equal to (1) the per share exercise price for the shares of Novadigm Common Stock otherwise purchasable pursuant to such Novadigm Option divided by (2) the Option Exchange Ratio, provided that such exercise price shall be rounded up to the nearest whole cent. Each assumed Novadigm Option shall be vested immediately following the Effective Time as to the same percentage of the total number of shares subject thereto as it was vested as to immediately prior to the Effective Time, except to the extent such Novadigm Option by its terms in effect prior to the date hereof provides for acceleration of vesting or the vesting of such Norton Option accelerates as described in Section 2.2(b) of the Norton Disclosure Letter. Prior to the Effective Time, the Company shall take all action necessary to effect the assumptions anticipated by this Section 5.9(a) under any outstanding Novadigm Options, including, but not limited to, any actions required by the applicable Novadigm Stock Plan.

(b) Termination of Novadigm Options Held by Former Novadigm Employees. At the Effective Time each then outstanding Novadigm Option held by a Novadigm Employee who is not employed by Novadigm or one of its Subsidiaries immediately prior to the Effective Time or does not become an employee of Parent or one of its Subsidiaries immediately after the Effective Time, shall by virtue of the Merger and without any action on the part of the Parent, Merger Sub, the Company or the holder thereof, whether or not exercisable at the Effective Time, be converted into and shall become a right to receive an amount in cash, without interest, with respect to each share subject thereto, equal to the excess, if any, of the Merger Consideration over the per share exercise price of such Novadigm Option (such amount being hereinafter referred to as the “Option Merger Consideration”) and each such Novadigm Option shall terminate at the Effective Time. The payment of the Option Merger Consideration shall be made as promptly as practicable to the holder of a Novadigm Option and shall be reduced by any income or employment tax

withholding required under the Code or any provision of state, local or foreign tax law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of such Novadigm Option. Prior to the Effective Time, the Company shall take all action necessary to effect the terminations anticipated by this Section 5.9(b) under any outstanding Novadigm Options, including, but not limited to, any actions required by the applicable Novadigm Stock Plan.

(c) Termination of Novadigm Purchase Plan. Prior to the Effective Time, the Novadigm Purchase Plan shall be terminated. The rights of participants in the Novadigm Purchase Plan with respect to any offering period then underway under such Novadigm Purchase Plan shall be determined by treating the last business day prior to the Effective Time, or an earlier date determined by Norton in accordance with the Norton Purchase Plan, as the last day of such offering period and by making such other pro-rata adjustments as may be necessary to reflect the shortened offering period but otherwise treating such shortened offering period as a fully effective and completed offering period for all purposes under such Novadigm Purchase Plan. Prior to the Effective Time, Novadigm shall take all actions (including, if appropriate, amending the terms of such Novadigm Purchase Plan) that are necessary to give effect to the transactions contemplated by this Section 5.9(c).

(d) Employment Offers; Service Credit; Vacation. At the sole discretion of Parent, certain employees of Novadigm or its Subsidiaries shall be offered employment by Parent and/or one of its Subsidiaries prior to the Closing Date (the “Offered Employees”), to be effective as of 12:01 a.m. (California time) on the first business day following the Effective Time (the “Offer”). Such Offers will (i) have terms and conditions, including the position and salary of such employee, which will be determined by Parent, and (ii) supersede any prior employment agreements and other arrangements with such employee in effect prior to the Closing Date (other than any proprietary rights and/or confidentiality agreements and except as provided in Section 5.9(d) of the Novadigm Disclosure Schedule). Each Offered Employee who delivers an executed Offer to Parent no later than the date specified by Parent in the Offer, shall be referred to herein as a “Continuing Employee.” Continuing Employees shall be eligible to receive benefits consistent with Parent’s applicable human resources policies and in accordance with the terms of Parent’s employee benefit plans. Each Continuing Employee shall receive credit for prior service with the Novadigm only for the purposes of determining the vacation accrual rate pursuant to Parent’s standard procedures and as set forth on Section 5.9(d) of the Novadigm Disclosure Schedule. Each Continuing Employee’s service for all other purposes shall be calculated based upon the date of hire by Parent. In addition, Parent or one of its Subsidiaries shall either carry over or pay to each Continuing Employee the cash

equivalent of his or her accrued but unused days of vacation or other paid time off, in each case as accrued immediately prior to the Closing Date, in a manner determined by Parent and consistent with state laws.

(e) Terminating Employees. Unless requested otherwise in writing by Parent within five (5) business days prior to the Closing Date, Novadigm shall terminate, effective no later than immediately prior to the Closing Date, (i) all employees of Novadigm and its Subsidiaries who are not Offered Employees, and (ii) all Offered Employees who do not deliver an executed Offer to Parent on the date specified by Parent in the Offer (the “Terminated Employees”). Novadigm shall provide the Terminated Employees the severance amounts provided on Section 5.9(d) of the Novadigm Disclosure Schedule in exchange for a release dated the date of such employee’s termination of employment with Novadigm or one of its Subsidiaries in a form reasonably satisfactory to Parent.

(f) Termination of Novadigm Plans. Effective as of no later than the day immediately preceding the Closing Date, each of Novadigm and any Novadigm ERISA Affiliate shall terminate any and all group severance plans or policies and any Novadigm Employee Plans intended to include a Code Section 401(k) arrangement (each, a “Novadigm Plan”) (unless Parent provides written notice to Novadigm that such Novadigm Plans shall not be terminated). Unless Parent provides such written notice to Novadigm, no later than three business days prior to the Closing Date, Novadigm shall provide Parent with evidence that such Novadigm Plan(s) have been terminated (effective no later than the day immediately preceding the Closing Date) pursuant to resolutions of the Board of Directors of Novadigm or such Novadigm ERISA Affiliate, as the case may be. The form and substance of such resolutions shall be subject to the prior review and approval of Parent. Novadigm also shall take such other actions in furtherance of terminating such Novadigm Plan(s) as Parent may reasonably require.

(g) Employee Communications. With respect to matters described in Section 5.9, Novadigm will use all reasonable efforts to consult with Parent (and consider in good faith the advice of Parent) prior to sending any notices or other communication materials to Novadigm Employees and Novadigm will not send any written notices or other written communication materials to Novadigm Employees without the prior written consent of Parent, which shall not be unreasonably withheld, conditioned or delayed.

(h) Form S-8. Parent agrees to file a registration statement on Form S-8 for the shares of Parent Common Stock issuable with respect to

assumed Novadigm Options, to the extent Form S-8 is available, as soon as is reasonably practicable after the Effective Time.

5.10 Indemnification.

(a) Indemnity. From and after the Effective Time, Parent will cause the Surviving Corporation to fulfill and honor in all respects the obligations of Novadigm pursuant to the Certificate of Incorporation and Bylaws of Novadigm as in effect on the date hereof, with respect to Novadigm’s directors and officers (the “Indemnified Parties”), subject to applicable law. The Certificate of Incorporation and Bylaws of the Surviving Corporation will contain provisions with respect to exculpation, indemnification and advancement of expenses that are at least as favorable to the Indemnified Parties as those contained in the Certificate of Incorporation and Bylaws of Novadigm as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect the rights thereunder of individuals who, immediately prior to the Effective Time, were directors or officers of Novadigm, unless such modification is required by law. From and after the Effective Time, Parent shall, to the fullest extent permitted under applicable law, cause the Surviving Corporation to fulfill and honor in all respects the obligations of Novadigm pursuant to any indemnification agreements between Novadigm and its officers and directors in effect prior to the date of this Agreement and listed on the Novadigm Disclosure Letter.

(b) Insurance. For a period of six years after the Effective Time, Parent will cause the Surviving Corporation to use all reasonable efforts to cause to be maintained the directors’ and officers’ liability insurance maintained by Novadigm covering those persons who are covered by Novadigm’s directors’ and officers’ liability insurance policy as of the date hereof on terms with respect to coverage and amount comparable to those applicable to the current directors and officers of Novadigm; provided, however, that in no event will the Surviving Corporation be required to expend in excess of one hundred seventy-five percent (175%) of the annual premium currently paid by Novadigm for such six years of coverage (and to the extent such aggregate premium would exceed one hundred seventy-five percent (175%) of the annual premium currently paid by Novadigm for such coverage, the Surviving Corporation shall use all reasonable efforts to cause to be maintained the maximum amount of coverage as is available for such one hundred seventy-five percent (175%) of such annual premium).

(c) Change of Control. In the event that Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the

continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any Person in a single transaction or a series of transactions, then, and in each such case, Parent or the Surviving Corporation, as applicable, shall make or cause to be made proper provision so that the successors and assigns of Parent or the Surviving Corporation, as applicable, assume by operation of law the obligations of Parent or the Surviving Corporation, as applicable, under this Section 5.10 for the benefit of the Indemnified Parties.

(d) Third–Party Beneficiaries. This Section 5.10 is intended to be for the benefit of, and shall be enforceable by the Indemnified Parties and their heirs and personal representatives and shall be binding on Parent and the Surviving Corporation and its successors and assigns.

5.11 Section 16 Matters. Prior to the Effective Time, Parent and Novadigm shall take all such steps as may be required (to the extent permitted under applicable law) to cause any dispositions of Novadigm Common Stock (including derivative securities with respect to Novadigm Common Stock) or acquisitions of derivative securities with respect to Parent Common Stock resulting from the transactions contemplated by Article I and Section 5.9 of this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Novadigm to be exempt under Rule 16b-3 promulgated under the Exchange Act.

7.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, by action taken or authorized by the Board of Directors of the terminating party or parties, and except as provided below, whether before or after the requisite approval of the stockholders of Novadigm:

(a) by mutual written consent duly authorized by Parent and the Board of Directors of Novadigm;

(b) by either Novadigm or Parent if the Merger shall not have been consummated by the date that is six (6) months from the date hereof; provided, however, that the right to terminate this Agreement under this Section 7.1(b) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Merger to occur on or before such date and such action or failure to act constitutes a material breach of this Agreement;

(c) by either Novadigm or Parent if a Governmental Entity shall have issued an order, decree or ruling or taken any other action (including the failure to have taken an action), in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger, which order, decree, ruling or other action is final and nonappealable;

(d) by either Novadigm or Parent if the required approval of the stockholders of Novadigm contemplated by this Agreement shall not have been obtained by reason of the failure to obtain the required vote at a meeting of the Novadigm stockholders duly convened therefor or at any adjournment thereof; provided, however, that the right to terminate this Agreement under this Section 7.1(d) shall not be available to Novadigm where the failure to obtain Novadigm stockholder approval shall have been caused by the action or failure to act of Novadigm and such action or failure to act constitutes a breach by Novadigm of this Agreement;

(e) by Parent (at any time prior to the adoption and approval of this Agreement and the Merger by the required vote of the stockholders of Novadigm) if a Triggering Event (as defined in Section 7.1(h)) with respect to Novadigm shall have occurred;

(f) by Novadigm, upon a breach of any representation, warranty, covenant or agreement on the part of Parent set forth in this Agreement, or if any representation or warranty of Parent shall have become untrue, in either case such that the conditions set forth in Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that if such inaccuracy in Parent’s representations and warranties or breach by Parent is curable by Parent in thirty (30) days through the exercise of reasonable efforts, then Novadigm may not terminate this Agreement under this Section 7.1(f) prior to thirty (30) days following the receipt of written notice from Novadigm to Parent of such breach, provided that Parent continues to exercise all reasonable efforts to cure such breach through such thirty (30) day period;

(g) by Parent, upon a breach of any representation, warranty, covenant or agreement on the part of Novadigm set forth in this Agreement, or if any representation or warranty of Novadigm shall have become untrue, in either case such that the conditions set forth in Section 6.3(a) or Section 6.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided, that if such inaccuracy in Novadigm’s representations and warranties or breach by Novadigm is curable by Novadigm in thirty (30) days through the exercise of reasonable efforts, then Parent may not terminate this Agreement under this Section 7.1(g) prior to thirty (30) days following the receipt of written notice from Parent to Novadigm of such breach, provided that Novadigm continues to exercise all reasonable efforts to cure such breach through such thirty (30) day period;

(h) by Parent, if a Material Adverse Effect on Novadigm shall have occurred since the date hereof; or

(i) by Novadigm, in order to enter a definitive acquisition agreement providing for a Superior Offer immediately after the termination of this Agreement, if the Novadigm Board of Directors (or any special committee thereof) in response to such Superior Offer that did not follow a breach of Section 5.2 or Section 5.3 determines in good faith, after consultation with its outside counsel, that the failure of the Board of Directors to terminate this Agreement would result in a breach of its fiduciary obligations to its stockholders under applicable law, provided that (i) Novadigm has, at least four business days prior to such termination, notified Parent in writing that it has received a Superior Offer and intends to enter into a definitive acquisition agreement providing for the consummation of such Superior Offer (such notice to include a copy of such definitive acquisition agreement) and (ii) Parent shall not have made, within four business days of receipt of such notice, a binding written offer that causes the Novadigm Board of Directors (or any special committee thereof) to no longer be able to determine in good faith, after consultation with its financial advisor and its legal counsel, that such Superior Offer remains a Superior Offer.

For the purposes of this Agreement, a “Triggering Event” shall be deemed to have occurred if: (i) Novadigm’s Board of Directors or any committee thereof shall for any reason have effected a Change of Recommendation, (ii) Novadigm shall have failed to include in the Proxy Statement the recommendation of its Board of Directors in favor of the adoption and approval of this Agreement and the approval of the Merger, (iii) Novadigm’s Board of Directors fails to reaffirm (publicly, if so requested) its recommendation in favor of the adoption and approval of the Agreement and the approval of the Merger within ten (10) business days after Parent requests in writing that such recommendation be reaffirmed after the public disclosure of an Acquisition Proposal, (iv) Novadigm’s Board of Directors or any committee thereof shall have approved or recommended, or (v) a tender or exchange offer relating to Novadigm securities shall have been commenced by a Person unaffiliated with the other party hereto and Novadigm shall not have sent to its securityholders pursuant to Rule 14e-2 promulgated under the Securities Act, within ten (10) business days after such tender or exchange offer is first published, sent or given, a statement disclosing that the Board of Directors of such party recommends rejection of such tender or exchange offer, or (vi) Novadigm shall have breached in any material respect its obligations under Sections 5.2 or 5.3 of this Agreement.

7.2 Notice of Termination; Effect of Termination. Except to the extent provided in Section 7.1(g), any termination of this Agreement under Section 7.1 above will be effective immediately upon the delivery of a valid written notice of

the terminating party to the other parties hereto. In the event of the termination of this Agreement as provided in Section 7.1, this Agreement shall be of no further force or effect, except (i) as set forth in Section 5.4(a), this Section 7.2, Section 7.3 and Article VIII, each of which shall survive the termination of this Agreement and (ii) nothing herein shall relieve any party from liability for any willful breach of this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement in accordance with their terms.

7.3 Fees and Expenses.

(a) General. Except as set forth in this Section 7.3, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the Merger is consummated; provided, however, that Parent and Novadigm shall share equally any necessary filing fee and expense (other than legal and accounting expenses) for the Notification and Report Forms filed with the FTC and DOJ under the HSR Act and premerger or merger notification and reports forms to be submitted to any other Governmental Entity under any local merger control laws or regulations of other jurisdictions, in each case pursuant to Section 5.6(a).

Such payment shall be made (A) promptly, but in no event later than three (3) business days after termination of this Agreement in the case of termination pursuant to Section 7.1(e), (B) prior to, or contemporaneously with, and as a condition to, Novadigm consummating an Acquisition or entering into an agreement providing for an Acquisition, as the case may be, in the case of termination pursuant to

Section 7.1(b), 7.1(d), or 7.1(g) and (C) prior to, or contemporaneously and as a condition to, Norton terminating this Agreement pursuant to Section 7.1(i).

(ii) Interest and Costs; Other Remedies. Novadigm acknowledges that the agreements contained in this Section 7.3(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not enter into this Agreement; accordingly, if Novadigm fails to pay in a timely manner the amounts due pursuant to this Section 7.3(b), and, in order to obtain such payment, Parent makes a claim that results in a judgment against Novadigm for the amounts set forth in this Section 7.3(b), Novadigm shall pay to Parent its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 7.3(b) at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made. Payment of the fees described in this Section 7.3(b) shall not be in lieu of damages incurred in the event of breach of this Agreement.

(iii) Definition of Acquisition. For the purposes of this Section 7.3(b) only, “Acquisition” shall mean any of the following transactions or series of transactions (other than the transactions contemplated by this Agreement): (i) a merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving Novadigm pursuant to which the stockholders of Novadigm immediately preceding such transaction hold less than 66²/₃% of the aggregate equity interests in the surviving or resulting entity of such transaction or any direct or indirect parent thereof, (ii) a sale or other disposition by Novadigm of assets representing in excess of 33¹/₃% of the aggregate fair market value of Novadigm’s business immediately prior to such sale, or (iii) the acquisition by any Person or group (including by way of a tender offer or an exchange offer or issuance by Novadigm or such Person or group), directly or indirectly, of beneficial ownership or a right to acquire beneficial ownership of shares representing in excess of 33¹/₃% of the voting power of the then outstanding shares of capital stock of Novadigm.

of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto, and (iii) waive compliance with any of the agreements or conditions for the benefit of such party contained herein.

For purposes of this Agreement, the words “include,” “includes” and “including,” when used herein, shall be deemed in each case to be followed by the words “without limitation.” The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. When reference is made herein to “the business of” an entity, such reference shall be deemed to include the business of all such entity and its Subsidiaries, taken as a whole.

(b) For purposes of this Agreement, the term “Material Adverse Effect,” when used in connection with Novadigm or any of its Subsidiaries, means any change, event, violation, inaccuracy, circumstance or effect (any such item, an “Effect”), individually or when taken together with all other Effects that have occurred prior to the date of determination of the occurrence of the Material Adverse Effect, that is or is reasonably likely to (i) be materially adverse to the business, assets (including intangible assets), capitalization, financial condition or results of operations of Novadigm taken as a whole with its Subsidiaries or (ii) materially adversely affect the ability of

For purposes of this Agreement, the term “Material Adverse Effect” when used in connection with Parent means any Effect, individually or when taken together with all other Effects that have occurred prior to the date of determination of the occurrence of the Material Adverse Effect, that is or is reasonably likely to materially adversely affect the ability of Parent or Merger Sub to consummate the transactions contemplated by this Agreement.

8.4 Counterparts. This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart.

8.5 Entire Agreement; Third-Party Beneficiaries. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Novadigm Disclosure Letter, (i) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements, understandings, representations and covenants both written and oral, among the parties with respect to the subject matter hereof, including the Letter Agreement, it being understood that the Confidentiality Agreement shall continue in full force and effect until the Closing and shall survive any termination of this Agreement and the parties hereto shall

continue to be entitled to exercise all rights and remedies with respect to any breaches of the Letter Agreement prior to date hereof, and (ii) are not intended to confer upon any other Person any rights or remedies hereunder, except as specifically provided, following the Effective Time, in Section 5.10.

8.6 Severability. In the event that any provision of this Agreement or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the greatest extent possible, the economic, business and other purposes of such void or unenforceable provision.

8.7 Other Remedies; Specific Performance.

(a) Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

(b) Specific Performance. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state or foreign country having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity, without the necessity of posting a bond or other security and without the necessity of showing actual damages.

8.8 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.

8.9 Consent to Jurisdiction. Each of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of any Delaware State court, for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby (and each agrees that no such action, suit or proceeding relating to this Agreement shall be brought by it or any

of its affiliates except in such courts). Each of the parties hereto further agrees that, to the fullest extent permitted by applicable law, service of any process, summons, notice or document by U.S. registered mail to such party’s respective address set forth above shall be effective service of process for any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of the parties hereto irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in any Delaware State court, or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

8.10 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

8.11 Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties. Any purported assignment in violation of this Section 8.11 shall be void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

8.12 Waiver of Jury Trial. EACH OF PARENT, MERGER SUB AND NOVADIGM HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF PARENT, MERGER SUB OR NOVADIGM IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

Item 3.	Source and Amount of Funds or Other Consideration
Item 3 of the Schedule 13D is hereby amended and supplemented as follows:
	On February 4, 2004, Hewlett-Packard, Norton Acquisition Corporation, a Delaware corporation and direct wholly-owned subsidiary of Hewlett-Packard (“Merger Sub”), and the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) (attached hereto as Exhibit 3), pursuant to which, among other things, Merger Sub would merge with and into the Issuer (the “Merger”) on the terms and subject to the conditions set forth therein. Pursuant to the terms of the Merger Agreement, each share of the Issuer’s common stock other than dissenting shares would be canceled and extinguished and automatically converted into the right to receive $6.10 in cash. Based on the 19,178,385 shares of common stock represented by the Issuer in the Merger Agreement to be outstanding as of January 30, 2004, the total consideration payable to the holders of common stock in the Merger will be $116,988,148.50, paid from the working capital of Hewlett-Packard or one of its affiliates.

Item 4.	Purpose of Transaction
Item 4 of the Schedule 13D is hereby amended and supplemented as follows:
	On February 4, 2004, Hewlett-Packard, Merger Sub and the Issuer entered into the Merger Agreement, pursuant to which the Merger would occur on the terms and subject to the conditions set forth therein. As described in Item 3 above, the Merger Agreement provides that holders of the Issuer’s common stock other than dissenting shares would receive upon consummation of the Merger an amount per share in cash equal to $6.10.
	The information set forth in response to this Item 4 is qualified in its entirety by reference to the Merger Agreement (attached hereto as Exhibit 3), which is expressly incorporated herein by reference.

Item 5.	Interest in Securities of the Issuer
Item 5 of the Schedule 13D is hereby amended and restated as follows:
	Hewlett-Packard is the beneficial owner of 1,190,000 shares of common stock of the Issuer, which represents 6.1% of the Issuer’s outstanding shares, after giving effect to the Warrant and based on the Issuer’s representation in the Merger Agreement that it had 19,178,385 shares outstanding as of January 30, 2004. Hewlett-Packard also has the right to vote an additional 6,688,181 shares of common stock (including shares of common stock that may be acquired upon exercise of options that are presently exercisable or will become exercisable within 60 days of January 30, 2004) pursuant to Voting Agreements with the Issuer’s directors and executive officers (as listed on Schedule A), although Hewlett-Packard disclaims beneficial ownership of these shares. Accordingly, Hewlett-Packard may be deemed to be the beneficial owner of 7,878,181 shares, or 38.9% of the Issuer’s outstanding shares of common stock. There have been no transactions by Hewlett-Packard in the Issuer’s common stock since the Amendment No. 1 to Schedule 13D filed by Hewlett-Packard with the Securities and Exchange Commission on December 11, 2003.

Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
Item 6 of the Schedule 13D is hereby amended and supplemented as follows:
	(d) The Merger Agreement is described and/or referred to in Item 4 and is attached hereto as Exhibit 3.
	(e) As an inducement for Hewlett-Packard to enter into the Merger Agreement, each of the Issuer’s directors and executive officers as listed on Schedule A, in his or her capacity as a stockholder, has entered into a Voting Agreement with Hewlett-Packard (collectively, the “Voting Agreements”), as described below and a copy of the form of which is attached hereto as Exhibit 4.
	Pursuant to the Voting Agreements, each of the stockholders who is a party thereto agreed, among other things, to vote his or her shares of common stock: (i) in favor of approval of the Merger, the adoption and execution and delivery by the Issuer of the Merger Agreement and in favor of each of the other actions contemplated by the Merger Agreement and any action required in furtherance thereof; (ii) against approval of any proposal made in opposition to, or in competition with, the Merger Agreement or the consummation of the Merger; and (iii) against any of the following actions (other than those actions that relate to the Merger and the transactions contemplated by the Merger Agreement): (A) any merger, consolidation, business combination, sale of assets, reorganization or recapitalization of the Issuer with any party, (B) any sale, lease or transfer of any significant part of the assets or capital stock of the Issuer, (C) any reorganization, recapitalization, dissolution, liquidation or winding up of the Issuer, (D) any material change in the capitalization of the Issuer or the Issuer’s corporate structure, or (E) any other action that is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or adversely affect the Merger or any of the other transactions contemplated by the Merger Agreement. In furtherance of the foregoing, each of the Issuer’s stockholders who is a party to a Voting Agreement granted Hewlett-Packard an Irrevocable Proxy to vote such stockholder’s shares of common stock as described above. The Voting Agreements and the Irrevocable Proxies will terminate on the earlier of (i) the date that the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement and (ii) the date that the Merger Agreement shall have been validly terminated pursuant to Article VII thereof.
	References to, and descriptions of, the Merger, the Merger Agreement, the Voting Agreements and the Irrevocable Proxies as set forth in this Schedule 13D are qualified in their entirety by the terms of the Merger Agreement, the Voting Agreements and the Irrevocable Proxies, which are incorporated herein by reference.
