(b) Subject to Section 3.01(a) and Section 3.09(b), each outstanding share of Oracle Stock issued and outstanding immediately prior to the Initial Effective Time shall be converted into the right to receive from Parent one fully paid and nonassessable share of Parent Stock (the “Oracle Merger Consideration”). All shares of Parent Stock issued pursuant to this Section 3.01(b) shall be duly authorized and validly issued and free of preemptive rights, with no personal liability attaching to the ownership thereof.

(c) Each share of Ozark Merger Sub common stock issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Oracle Surviving Corporation.

Section 3.02. Siebel and Sierra Merger Sub. At the Effective Time, by virtue of the Siebel Merger and without any action on the part of Siebel, Parent, Sierra Merger Sub or any holder of any shares of Siebel Stock:

(a) All shares of Siebel Stock that are held by Siebel as treasury stock or that are owned by Siebel, Sierra Merger Sub or any Subsidiary of Siebel immediately prior to the Effective Time shall cease to be outstanding and shall be cancelled and retired and shall cease to exist and no consideration shall be delivered in exchange therefor.

(b) Subject to Sections 3.02(a), 3.04, 3.05, 3.06, Section 3.08(b) and 3.11, each share of Siebel Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive from Parent either the Stock Election Price or the Cash Election Price (the Stock Election Price or Cash Election Price, as applicable, the “Siebel Merger Consideration”) with the form of Siebel Merger Consideration determined as follows:

(i) each share of Siebel Stock with respect to which an election to receive stock has been made and not revoked or converted into the right to receive the Cash Election Price pursuant to Section 3.04(b) (each, a “Stock Electing Siebel Share”) shall be converted into the right to receive the number of shares of Parent Stock (the “Stock Election Price”) equal to $10.66 divided by the Average Oracle Stock Price (the “Exchange Ratio”); and

(ii) each other share of Siebel Stock shall be converted into the right to receive an amount equal to $10.66 in cash without interest (the “Cash Election Price”).

(c) Each share of Sierra Merger Sub common stock issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Siebel Surviving Corporation.

Section 3.03. Elections. (a) Each Person (other than Parent, Siebel, Sierra Merger Sub or any other Subsidiary of Siebel) who, as of a date to be mutually agreed by Oracle and Siebel and which shall be no fewer than 20 Business Days prior to the Election Deadline (the “Election Record Date”), is a record holder of Siebel Stock will be entitled, with respect to all (but not less than all) of such shares of Siebel Stock, to make an election (a “Stock Election”), on or prior to the Election Deadline, to receive the Stock Election Price on the basis hereinafter set forth.

(b) Prior to the Election Record Date, Parent shall prepare a form, in form and substance reasonably acceptable to Siebel (an “Election Form”), pursuant to which a holder of record of shares of Siebel Stock may make a Stock Election with respect to all (but not less than all) of the shares of Siebel Stock owned by such holder. Parent shall cause the Exchange Agent to mail an Election Form, as promptly as practicable following the Election Record Date, to each holder of record of shares of Siebel Stock as of the close of business on the Election Record Date.

(c) Subject to Section 2.06(b), a Stock Election shall be effective only if the Exchange Agent shall have received no later than 5:00 p.m., New York time, on a date selected by Oracle (which date shall be not earlier than 20 Business Days, and not later than two Business Days, prior to the Effective Time) (the “Election Deadline”) an Election Form covering the shares of Siebel Stock to which such Stock Election applies, executed and completed in accordance with the instructions set forth in such Election Form. Any share of Siebel Stock with respect to which the Exchange Agent has not received an effective Stock Election meeting the requirements of this Section 3.03(c) by the Election Deadline shall be deemed not to be a Stock Electing Siebel Share. A Stock Election may be revoked or changed only by delivering to the Exchange Agent, prior to the Election Deadline, a written notice of revocation or, in the case of a change, a properly completed revised Election Form that identifies the shares of Siebel Stock to which such revised Election Form applies. Delivery to the Exchange Agent prior to the Election Deadline of a revised Election Form with respect to any shares of Siebel Stock shall result in the revocation of all prior Election Forms with respect to all such shares of Siebel Stock. Any termination of this Agreement in accordance with Article 9 shall result in the revocation of all Election Forms delivered to the Exchange Agent on or prior to the date of such termination.

(d) Oracle shall have the right to make rules, not inconsistent with the terms of this Agreement, governing the validity and effectiveness of Election Form and the manner and extent to which Stock Elections are to be taken into account in making the determinations required by this Article.

Section 3.04. Proration of Election Price. (a) The number of shares of Siebel Stock eligible to be converted into the right to receive the Stock Election Price at the Effective Time shall not exceed the number of shares of Siebel Stock which is equal to 30% of the shares of Siebel Stock outstanding immediately prior to the Effective Time (excluding any shares of Siebel Stock to be canceled pursuant to Section 3.02(a)) (the “Stock Election Number”).

(b) If the number of Stock Electing Siebel Shares exceeds the Stock Election Number, then such Stock Electing Siebel Shares shall be treated in the following manner:

(i) A stock proration factor (the “Stock Proration Factor”) shall be determined by dividing the Stock Election Number by the total number of Stock Electing Siebel Shares.

(ii) A number of Stock Electing Siebel Shares covered by each stockholder’s Stock Election equal to the product of (x) the Stock Proration Factor and (y) the total number of Stock Electing Siebel Shares covered by such Stock Election shall be converted into the right to receive the Stock Election Price.

(iii) Each Stock Electing Siebel Share, other than those shares of Siebel Stock converted into the right to receive the Stock Election Price in accordance with Section 3.04(b)(ii), shall be converted into the right to receive the Cash Election Price as if such Shares of Siebel Stock were not Stock Electing Siebel Shares.

(c) If the number of Stock Electing Siebel Shares is less than or equal to the Stock Election Number, then each Stock Electing Siebel Share shall be converted into the right to receive the Stock Election Price and each other share of Siebel Stock (other than shares of Siebel Stock to be canceled pursuant to Section 3.02(a)) shall be converted into the right to receive the Cash Election Price.

Section 3.05. Dissenting Shares. Notwithstanding Section 3.02, shares of Siebel Stock outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Siebel Merger or consented thereto in writing and who has demanded appraisal for such shares in accordance with the DGCL shall

not be converted into a right to receive the Siebel Merger Consideration, unless such holder fails to perfect, withdraws or otherwise loses its right to appraisal. If, after the Effective Time, such holder fails to perfect, withdraws or loses its right to appraisal, such shares of Siebel Stock shall be treated as if they had been converted as of the Effective Time into a right to receive the Siebel Merger Consideration. Siebel shall give Oracle prompt notice of any demands received by Siebel for appraisal of shares of Siebel Stock, and Oracle shall have the right to participate in all negotiations and proceedings with respect to such demands. Except with the prior written consent of Oracle, or to the extent required by applicable law, Siebel shall not make any payment with respect to, or offer to settle or settle, any such demands.

Section 3.06. Certain Adjustments. If, between the date of this Agreement and the Effective Time, there is a reclassification, recapitalization, stock split, split-up, stock dividend, combination or exchange of shares with respect to, or rights issued in respect of, Oracle Stock or Siebel Stock, the Siebel Merger Consideration shall be adjusted accordingly to provide to the holders of Siebel Stock the same economic effect as contemplated by this Agreement prior to such event.

Section 3.07. Effect on Parent Stock. Immediately following the Effective Time, shares of the capital stock of Parent owned by the Oracle Surviving Corporation shall be cancelled by Parent without payment therefor.

Section 3.08. Siebel Stock Options and Restricted Stock Awards. (a) As of the Effective Time, each stock option outstanding under any stock option or compensation plan, agreement or arrangement of Siebel (each, a “Siebel Option”) that is outstanding immediately prior to the Effective Time, whether or not then vested or exercisable, shall cease to represent a right to acquire Siebel Stock and shall be converted automatically into an option to purchase shares of Parent Stock on substantially the same terms and conditions (including vesting schedule) as applied to such Siebel Option immediately prior to the Effective Time, except that (i) the number of shares of Parent Stock subject to each assumed Siebel Option shall be determined by multiplying the number of shares of Siebel Stock subject to such Siebel Option by a fraction (the “Option Exchange Ratio”), the numerator of which is the closing sale price of a share of Siebel Stock as reported on the Nasdaq, as of the close of business on the trading day immediately preceding the date on which the Effective Time occurs, and the denominator of which is the average closing price of Oracle Stock on the Nasdaq over the ten trading days immediately preceding (but not including) the date on which the Effective Time occurs (rounded down to the nearest whole share), at an exercise price per share of Parent Stock (rounded up to the nearest whole cent) equal to (x) the per share exercise price for the shares of Siebel Stock otherwise purchasable pursuant to such Siebel Option divided by (y) the Option Exchange Ratio.

(b) Effective as of the Effective Time, each Restricted Stock Award with respect to which shares of Siebel Stock remain unvested or unissued as of the Effective Time shall be converted automatically into a substantially similar award for Parent Stock and shall remain subject to the vesting conditions in effect on the date hereof, except that the number of shares of Parent Stock subject to each such assumed award shall be determined by multiplying the number of shares of Sierra Stock subject to such Restricted Stock Award by the Option Exchange Ratio.

(c) Prior to the Effective Time, Siebel shall provide to Oracle an updated schedule that identifies as of the Effective Time with respect to each Siebel Option and Siebel Restricted Stock Award, (i) the name of the holder, (ii) the number of shares subject to such award, (iii) the Employee Plan under which the award was issued, (iv) the exercise price of each Siebel Option, (v) the number of shares vested, (vi) the vesting schedule, (vii) the grant date, and (viii) the expiration date.

Section 3.09. Oracle Stock Options and Restricted Stock Awards. As of the Initial Effective Time, (a) each stock option outstanding under any stock option or compensation plan or arrangement of Oracle (each, an “Oracle Option”) that is outstanding immediately prior to the Initial Effective Time, whether or not then vested or exercisable, shall cease to represent a right to acquire Oracle Stock and shall be converted automatically into an option to purchase the same number of shares of Parent Stock, on substantially the same terms and conditions

(including vesting schedule and per share exercise price) as applied to such Oracle Option immediately prior to the Effective Time and (b) each share of Oracle restricted stock and each restricted stock unit of Oracle that is not vested on or prior to the Initial Effective Time that is outstanding under any stock option or compensation plan, agreement or arrangement of Oracle immediately prior to the Initial Effective Time, whether or not then vested or exercisable, shall cease to represent a share of Oracle restricted stock or an Oracle restricted stock unit and shall be converted automatically into a share of restricted stock or a restricted stock unit, as the case may be, of Parent, on substantially the same terms and conditions (including vesting schedule) as applied to such Oracle restricted stock or restricted stock unit immediately prior to the Initial Effective Time.

Section 3.10. Surrender and Payment. (a) Prior to the Election Record Date, Parent shall appoint an agent (the “Exchange Agent”) for the purpose of (i) mailing and receiving Election Forms and determining, in accordance with this Article 3, the form of Siebel Merger Consideration to be received by each holder of shares of Siebel Stock, and (ii) exchanging the applicable Siebel Merger Consideration (A) for certificates representing shares of Siebel Stock (the “Certificates”) or (B) for uncertificated shares of Siebel Stock (the “Uncertificated Shares”). Parent shall make available to the Exchange Agent, as needed, the applicable Siebel Merger Consideration to be issued or paid in respect of the Certificates and the Uncertificated Shares. Promptly after the Effective Time, Parent shall send, or shall cause the Exchange Agent to send, to each record holder of Siebel Stock at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Exchange Agent) for use in such exchange; provided, that any such letter of transmittal and instructions shall be sent to holders of Uncertificated Shares only to the extent determined necessary by Oracle and the Exchange Agent to effect the transactions contemplated hereby.

(b) Each holder of shares of Siebel Stock that have been converted into the right to receive the Siebel Merger Consideration shall be entitled to receive, upon (i) surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Siebel Merger Consideration in respect of the Siebel Stock represented by a Certificate or Uncertificated Share. The shares of Parent Stock constituting part of such Siebel Merger Consideration (if any), at Parent’s option, shall be in uncertificated book-entry form, unless a physical certificate is requested by a holder of shares of Siebel Stock or is otherwise required under applicable law. Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Share shall represent after the Effective Time for all purposes only the right to receive such Siebel Merger Consideration.

(c) If any portion of the Siebel Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Exchange Agent that such taxes have been paid or are not payable.

(d) After the Effective Time, there shall be no further registration of transfers of shares of Siebel Stock. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Siebel Surviving Corporation, they shall be canceled and exchanged for the applicable Siebel Merger Consideration, in accordance with the procedures set forth in this Section 3.10.

(e) Any portion of the Siebel Merger Consideration made available by Parent to the Exchange Agent pursuant to Section 3.10(a) that remains unclaimed by the holders of shares of Siebel Stock six months after the Effective Time shall be returned to Parent upon demand, and any such holder who has not exchanged shares of Siebel Stock for the Siebel Merger Consideration in accordance with this Section 3.10 prior to that time shall thereafter look only to Parent for payment of the Siebel Merger Consideration, and any dividends and

distributions with respect thereto, in respect of such shares without any interest thereon. Notwithstanding the foregoing, Parent shall not be liable to any holder of shares of Siebel Stock for any amounts paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of shares of Siebel Stock two years after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Entity) shall become, to the extent permitted by applicable law, the property of Parent, free and clear of any claims or interest of any Person previously entitled thereto.

(f) No dividends or other distributions with respect to Parent Stock constituting part of the Siebel Merger Consideration, and no cash payment in lieu of fractional shares as provided in Section 3.11, shall be paid to the holder of any Certificates not surrendered or of any Uncertificated Shares not transferred until such Certificates or Uncertificated Shares are surrendered or transferred, as the case may be, as provided in this Section. Following such surrender or transfer, there shall be paid, without interest, to the Person in whose name the securities of Parent have been registered, (i) at the time of such surrender or transfer, the amount of any cash payable in lieu of fractional shares to which such Person is entitled pursuant to Section 3.11 and the amount of all dividends or other distributions with a record date after the Effective Time previously paid or payable on the date of such surrender with respect to such securities and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and prior to surrender or transfer and with a payment date subsequent to surrender or transfer payable with respect to such securities.

(g) Any portion of the Siebel Merger Consideration made available to the Exchange Agent pursuant to Section 3.10(a) or Section 3.11 to pay for shares of Siebel Stock for which appraisal rights have been perfected shall be returned to Parent, upon demand.

(h) Certificates representing shares of Oracle Stock immediately prior to the Initial Effective Time shall, from and after the Initial Effective Time, represent the shares of Parent Stock constituting the Oracle Merger Consideration. At the Effective Time, the Exchange Agent shall exchange by book entry transfer all uncertificated shares of Oracle Stock (excluding any shares of Oracle Stock to be canceled pursuant to Section 3.01(a)) for the shares of Parent Stock constituting the Oracle Merger Consideration. No separate certificates shall be issued in exchange for Oracle Stock in accordance with Section 251(g) of DGCL.

Section 3.11. No Fractional Shares of Parent Stock. No fractional shares of Parent Stock shall be issued in the Siebel Merger. All fractional shares of Parent Stock that a holder of shares of Siebel Stock would otherwise be entitled to receive as a result of the Siebel Merger shall be aggregated and if a fractional share results from such aggregation, such holder shall be entitled to receive, in lieu thereof, an amount in cash, without interest, determined by multiplying such fractional share by the closing price of Oracle Stock on the trading day immediately preceding the Closing Date. As soon as practicable after the determination of the amount of cash to be paid to such former holders of Siebel Stock in lieu of any fractional interests, the Exchange Agent shall notify Parent, and Parent shall ensure that there is deposited with the Exchange Agent and shall cause the Exchange Agent to make available in accordance with this Agreement such amounts to such former holders of Siebel Stock.

Section 3.12. Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the Siebel Merger Consideration with respect to the shares of Siebel Stock formerly represented thereby, and unpaid dividends and distributions on shares of Parent Stock deliverable in respect thereof pursuant to this Agreement.

Section 3.13. Withholding Rights. Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law. To the extent

that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity by or on behalf of Parent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by or on behalf of Parent.

Section 3.14. Further Assurances. At and after the Effective Time, the officers and directors of Parent, the Oracle Surviving Corporation or the Siebel Surviving Corporation, as applicable, shall be authorized to execute and deliver, in the name and on behalf of the Oracle Surviving Corporation, Ozark Merger Sub or Oracle, or the Siebel Surviving Corporation, Sierra Merger Sub or Siebel, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Oracle Surviving Corporation, Ozark Merger Sub or Oracle, or the Siebel Surviving Corporation, Sierra Merger Sub or Siebel, any other actions and things necessary to vest, perfect or confirm of record or otherwise in Parent, the Oracle Surviving Corporation or the Siebel 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 Parent, the Oracle Surviving Corporation or the Siebel Surviving Corporation, as applicable, as a result of, or in connection with, the Mergers.

Section 4.01. Corporate Existence and Power. Siebel is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has all corporate powers required to carry on its business as now conducted. Siebel is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where such qualification is necessary, except for those jurisdictions where failure to be so qualified would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siebel. True and complete copies of the certificate of incorporation and bylaws of Siebel as currently in effect have been filed with the SEC and referenced as exhibits in the Siebel 10-K.

Section 4.02. Corporate Authorization. (a) The execution, delivery and performance by Siebel of this Agreement and the consummation by Siebel of the transactions contemplated hereby are within Siebel’s corporate powers and, except for the required approval of Siebel’s stockholders in connection with the consummation of the Siebel Merger, have been duly authorized by all necessary corporate action on the part of Siebel. The affirmative vote of the holders of a majority of the outstanding shares of Siebel Stock voting to adopt this Agreement (the “Siebel Stockholder Approval”) is the only vote of the holders of any of Siebel’s capital stock necessary in connection with the consummation of the transactions contemplated by this Agreement. This Agreement constitutes a valid and binding agreement of Siebel enforceable against Siebel in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium and other similar Laws affecting creditors’ rights generally and by general principles of equity.

(b) At a meeting duly called and held, prior to the execution of this Agreement, Siebel’s Board of Directors has unanimously (i) determined that this Agreement and the transactions contemplated hereby are advisable and in the best interest of Siebel’s stockholders, (ii) approved and adopted this Agreement and the transactions contemplated hereby and (iii) resolved (subject to Section 6.03) to recommend that Siebel’s stockholders adopt this Agreement.

Section 4.03. Governmental Authorization.

business, (b) compliance with any applicable requirements of the HSR Act and of laws, rules and regulations analogous to the HSR Act existing in foreign jurisdictions, (c) compliance with any applicable requirements of the 1933 Act, the 1934 Act, and any other applicable securities laws, whether federal, state or foreign, (d) compliance with any applicable requirements of Nasdaq and (e) any actions or filings the absence of which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siebel.

Section 4.04. Non-contravention. The execution, delivery and performance by Siebel of this Agreement and the consummation by Siebel of the transactions contemplated hereby do not and will not (a) contravene, conflict with, or result in any violation or breach of any provision of the certificate of incorporation or bylaws of Siebel, (b) assuming compliance with the matters referred to in Section 4.03 and that the Siebel Stockholder Approval is obtained, contravene, conflict with or result in a violation or breach of any provision of any applicable Law, (c) require any consent under, constitute a default, or an event that, with or without notice or lapse of time or both, would constitute a default under, or cause or permit the termination, cancellation, acceleration or other change of any right or obligation or the loss of any benefit to which Siebel or any of its Subsidiaries is entitled under, any provision of any Siebel Significant Contract or any other Contract material to Siebel and its Subsidiaries, or any Permit affecting, or relating in any way to, the assets or business of Siebel and its Subsidiaries or (d) result in the creation or imposition of any Lien on any asset of Siebel or any of its Subsidiaries, in each case except for such contraventions, conflicts and violations referred to in clause (b) and such failures to obtain any such consent or other action, defaults, terminations, cancellations, accelerations, changes, losses or Liens referred to in clauses (c) and (d) that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siebel (provided that the matters described in clause (a) of the definition of Material Adverse Effect shall be taken into account and not excluded for the purposes of determining whether or not a Material Adverse Effect shall have occurred under this Section 4.04).

Section 4.05. Capitalization. (a) The authorized capital stock of Siebel consists of 2,000,000,000 shares of Siebel Stock and 2,000,000 shares of preferred stock, $0.001 par value per share, of Siebel.

All outstanding shares of capital stock of Siebel have been, and all shares that may be issued pursuant to any equity compensation plan of Siebel will be, when issued in accordance with the respective terms thereof, duly authorized and validly issued and are (or, in the case of shares that have not yet been issued, will be) fully paid, nonassessable and free of preemptive rights. No Subsidiary of Siebel owns any shares of capital stock of Siebel.

(b) Except (i) as set forth in this Section 4.05, (ii) for changes since September 9, 2005 resulting from the exercise of Siebel Options and settlement of Restricted Stock Units outstanding on such date, (iii) for 1,259,142 outstanding exchangeable shares of Siebel Janna Arrangement, Inc. (the “Exchangeable Shares”) (which are exchangeable into the same number of shares of Siebel Stock as of August 23, 2005), and (iv) for the shares and conversion rights designated in connection with the Rights Agreement dated as of January 29, 2003, between Siebel and Mellon Investors Services LLC, as Rights Agent (the “Siebel Rights Agreement”), as of the date of this Agreement, there are no outstanding (A) shares of capital stock or voting securities of Siebel, (B) securities of Siebel convertible into or exchangeable for shares of capital stock or voting securities of Siebel, (C) options, warrants or other rights or arrangements to acquire from Siebel, or other obligations or commitments of Siebel to issue, any capital stock, voting securities or securities convertible into or exchangeable for capital stock or voting securities of Siebel (the items in clauses (A), (B) and (C) being referred to collectively as the “Siebel Securities”), (D) voting trusts, proxies or other similar agreements or understandings to which Siebel or any of its Subsidiaries is a party or by which Siebel or any of its Subsidiaries is bound with respect to the voting of any shares of capital stock of Siebel or any of its Subsidiaries or (v) contractual obligations or commitments of any character to which Siebel or any of its Subsidiaries is a party or by which Siebel or any of its Subsidiaries is

Other than the obligations reflected in the terms of the Siebel Securities referred to in this Section 4.05, there are no outstanding obligations of Siebel or any of its Subsidiaries to repurchase, redeem or otherwise acquire any of the Siebel Securities.

(c) Siebel has provided to Oracle a schedule that identifies, with respect to each Siebel Option and Siebel Restricted Stock Award issued as of September 9, 2005, (i) the number of shares subject to such award, (ii) the exercise price or purchase price (if applicable) of each Siebel Option and Siebel Restricted Stock Award, (iii) the number of shares vested, (iv) the vesting schedule and (v) the grant date.

Section 4.06. Subsidiaries. (a) Each Significant Subsidiary (as defined in Regulation S-K under the 1934 Act; provided however that the 10% threshold referred to in such definition shall be deemed to be 5% for the purposes of this Agreement) of Siebel is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation and has all corporate powers required to carry on its business as now conducted. Each such Significant Subsidiary is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where such qualification is necessary, except for those jurisdictions where failure to be so qualified would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siebel. All Significant Subsidiaries of Siebel and their respective jurisdictions of incorporation are identified in the Siebel 10-K.

(b) Other than the Exchangeable Shares, all of the outstanding capital stock of, or other voting securities or ownership interests in, each Subsidiary of Siebel, is owned by Siebel, directly or indirectly, free and clear of any Lien and free of any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other voting securities or ownership interests). Other than the Exchangeable Shares, there are no outstanding (i) securities of Siebel or any of its Subsidiaries convertible into or exchangeable for shares of capital stock or other voting securities or ownership interests in any Subsidiary of Siebel or (ii) options, warrants or other rights or arrangements to acquire from Siebel or any of its Subsidiaries, or other obligations or commitments of Siebel or any of its Subsidiaries to issue, any capital stock or other voting securities or ownership interests in, or any securities convertible into or exchangeable for any capital stock or other voting securities or ownership interests in, any Subsidiary of Siebel (the items in clauses (i) and (ii) being referred to collectively as the “Siebel Subsidiary Securities”). Other than the obligations reflected in the terms of the Exchangeable Shares, there are no outstanding obligations of Siebel or any of its Subsidiaries to repurchase, redeem or otherwise acquire any of the Siebel Subsidiary Securities.

(b) As of its filing date, except as set forth in a subsequent Siebel SEC Document filed prior to the date of this Agreement, each Siebel SEC Document complied as to form in all material respects with the applicable requirements of the 1933 Act and the 1934 Act, as the case may be, each as in effect on its respective filing date.

(c) As of its filing date (or, if amended or superseded by a filing prior to the date hereof, on the date of such filing), each Siebel SEC Document filed pursuant to the 1934 Act did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

(d) Each Siebel SEC Document that is a registration statement, as amended or supplemented, if applicable, filed pursuant to the 1933 Act, as of the date such registration statement or amendment became effective, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading.

(e) Each required form, report and document containing financial statements that has been filed with or submitted to the SEC by Siebel since July 31, 2002, was accompanied by the certifications required to be filed or submitted by Siebel’s chief executive officer and/or chief financial officer, as required, pursuant to the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and, at the time of filing or submission of each such certification, such certification was true and accurate and complied with the Sarbanes-Oxley Act. As of the date of this Agreement, no Subsidiary of Siebel is subject to the periodic reporting requirements of the 1934 Act.

Section 4.08. Financial Statements: Internal Controls. (a) The audited consolidated financial statements and unaudited consolidated interim financial statements of Siebel included in the Siebel SEC Documents fairly present, in conformity with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis (except as may be indicated in the notes thereto), the consolidated financial position of Siebel and its consolidated Subsidiaries as of the dates thereof and their consolidated results of operations and cash flows for the periods then ended (subject to normal year-end adjustments in the case of any unaudited interim financial statements).

(b) Siebel’s system of internal controls over financial reporting are reasonably sufficient in all material respects to provide reasonable assurance (i) that transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP, (ii) that receipts and expenditures are executed in accordance with the authorization of management and (iii) regarding prevention or timely detection of the unauthorized acquisition, use or disposition of Siebel’s assets that would materially affect Siebel’s financial statements.

(c) Siebel’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the 1934 Act) are reasonably designed to ensure that (i) all material information (both financial and non-financial) required to be disclosed by Siebel in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported to the individuals responsible for preparing such reports within the time periods specified in the rules and forms of the SEC and (ii) all such information is accumulated and communicated to Siebel’s management or to other individuals responsible for preparing such reports as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the principal executive officer and principal financial officer of Siebel required under the 1934 Act with respect to such reports.

(d) Since the date of their last certification filed with the SEC, neither the chief executive officer nor the chief financial officer of Siebel has become aware of any fact, circumstance or change that is reasonably likely to result in a “significant deficiency” or a “material weakness” in Siebel’s internal controls over financial reporting.

Siebel has promptly disclosed any change in or waiver of Siebel’s code of ethics with respect to any such persons, as required by Section 406(b) of SOX. To the Knowledge of Siebel, there have been no violations of provisions of Siebel’s code of ethics by any such persons.

Section 4.09. Information Provided. The information supplied by Siebel for inclusion or incorporation in the registration statement on Form S-4 or any amendment or supplement thereto pursuant to which shares of Parent Stock issuable in the Mergers will be registered with the SEC (the “Registration Statement”) shall not at the

time the Registration Statement is declared effective by the SEC (or, with respect to any post-effective amendment or supplement, at the time such post-effective amendment or supplement becomes effective) contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The information supplied by Siebel for inclusion in the proxy statement/prospectus, or any amendment or supplement thereto, to be sent to Siebel stockholders in connection with the Siebel Merger and the other transactions contemplated by this Agreement (the “Proxy Statement”) shall not, on the date the Proxy Statement is first mailed to the Siebel stockholders or at the time of the Siebel Stockholder Approval, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

Section 4.11. No Undisclosed Material Liabilities. There are no liabilities or obligations of Siebel or any of its Subsidiaries of any kind whatsoever, whether accrued, contingent, absolute, determined, determinable or otherwise, and there is no existing condition, situation or set of circumstances that could reasonably be expected to result in such a liability or obligation, other than:

respective employees (insofar as any such investigation or review relates to their activities with Siebel or any of its Subsidiaries) actually pending or threatened, nor has any Governmental Entity or self-regulatory authority indicated to Siebel or any of its Subsidiaries in writing or, to the Knowledge of Siebel, verbally, an intention to conduct the same that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siebel.

Section 4.13. Compliance With Applicable Law.

(a) Siebel and its Subsidiaries and their businesses and operations are, and since January 1, 2003 have been, in compliance in all material respects with all material Laws applicable to Siebel or such Subsidiaries.

Since January 1, 2003, there have occurred no defaults (with or without notice or lapse of time or both) under, violations of, or events giving to others any right of termination, amendment or cancellation, with or without notice or lapse of time or both, of, any such Permit, except for such defaults, violations and events that, individually and in the aggregate, have not had and would not reasonably be expected to have a Material Adverse Effect on Siebel. The transactions contemplated hereby would not reasonably be expected to cause the revocation or cancellation (with or without notice or lapse of time or both) of any such Permit that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on Siebel.

As of its filing date (or, if amended or superseded by a filing prior to the date hereof, on the date of such filing), each Oracle SEC Document filed pursuant to the 1934 Act did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

Section 5.13. Financial Statements. The audited consolidated financial statements of Oracle included in the Oracle SEC Documents fairly present, in conformity with GAAP applied on a consistent basis (except as may be indicated in the notes thereto), the consolidated financial position of Oracle and its consolidated Subsidiaries as of the dates thereof and their consolidated results of operations and cash flows for the periods then ended.

(d) Notwithstanding anything to the contrary herein, nothing in this Agreement shall require Oracle, Parent or any of their Subsidiaries to (i) agree to or to effect any divesture, hold separate, or enter into any license or similar agreement with respect to, or agree to restrict its ownership or operation of, any business or assets of Siebel or its Subsidiaries or of Oracle, Parent and their Subsidiaries, (ii) enter into, amend, or agree to enter into or amend, any Contracts of Siebel or its Subsidiaries or of Oracle, Parent and their Subsidiaries, (iii) otherwise waive, abandon or alter any material rights or obligations of Siebel or its Subsidiaries or of Oracle, Parent and their Subsidiaries or (iv) file or defend any lawsuit, appeal any Judgment or contest any injunction issued in a proceeding initiated by a Governmental Entity.

deliver to Davis Polk & Wardwell and to Cooley Godward LLP a tax representation letter in the form of Exhibit B hereto; and (c) Parent shall execute and deliver to Davis Polk & Wardwell and to Cooley Godward LLP a tax representation letter in the form of Exhibit C hereto.

Each of Parent, Oracle and Siebel shall use its reasonable best efforts to have the Proxy Statement cleared by the SEC and the Registration Statement declared effective under the 1933 Act by the SEC as promptly as practicable after such filing and Parent and Oracle shall use their reasonable best efforts to keep the Registration Statement effective as long as is necessary to consummate the Mergers and the transactions contemplated hereby. As promptly as practicable following the date hereof, each of Parent, Oracle and Siebel shall make all other filings required to be made by it with respect to the Mergers and the transactions contemplated hereby under the 1933 Act and the 1934 Act and applicable state “blue sky” Laws and the rules and regulations thereunder. Each of Parent, Oracle and Siebel shall, as promptly as practicable after receipt thereof, provide the other parties with copies of any written comments, and advise each other of any oral comments, with respect to the Proxy Statement or Registration Statement received from the SEC. Siebel shall use reasonable best efforts to cause the Proxy Statement to be mailed to Siebel’s stockholders as promptly as practicable after the Registration Statement is declared effective under the 1933 Act. Each of Parent, Oracle and Siebel will advise the other party, promptly after it receives notice thereof, of the time when the Registration Statement has become effective, the issuance of any stop order, the suspension of the qualification of the Parent Stock issuable in connection with the Mergers for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Proxy Statement or the Registration Statement. If, at any time prior to the Effective Time, any information relating to Oracle or Siebel, or any of their respective Affiliates, officers or directors, is discovered by Oracle or Siebel that should be set forth in an amendment or supplement to any of the Registration Statement or the Proxy Statement so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party hereto discovering such information shall promptly notify the other parties and, to the extent required by Law, the parties shall cause an appropriate amendment or supplement describing such information to be promptly filed with the SEC and, to the extent required by Law, disseminated to the stockholders of Siebel.

Section 7.03. Certain Filings. Siebel and Oracle shall cooperate with one another (i) in determining whether any action by or in respect of, or filing with, any Governmental Entity is required, or any actions, consents, approvals or waivers are required to be obtained from parties to any material contracts, in connection with the consummation of the transactions contemplated by this Agreement and (ii) in taking such reasonable actions or making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such actions, consents, approvals or waivers.

Section 7.04. Public Announcements. Oracle and Siebel shall consult with each other before issuing any press release, making any other public statement or scheduling any press conference or conference call with investors or analysts with respect to this Agreement or the transactions contemplated hereby (provided that Siebel need not consult with Oracle in connection with any press release, public statement, press conference or conference call with respect to any Acquisition Proposal or any Change in Recommendation not in violation of this Agreement) and, except as may be required by applicable Law, order of a court of competent jurisdiction or any listing agreement with or rule of any national securities exchange or association, shall not issue any such press release, make any such other public statement or schedule any such press conference or conference call before any required consultation as contemplated by this Section 7.04.

Section 7.05. Access to Information. From the date hereof until the Effective Time and subject to applicable Law and the NDA, Siebel and Oracle shall (a) give to the other party, its counsel, financial advisors, auditors and

other authorized representatives reasonable access during normal business hours to the offices, properties, books and records of such party, (b) furnish to the other party, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (c) instruct its employees, counsel, financial advisors, auditors and other authorized representatives to cooperate with the other party in its investigation; provided, however, that any party hereto may restrict the foregoing access to the extent that (i) any Law applicable to such party requires such party or its subsidiaries to restrict or prohibit access to any such properties or information, (ii) such disclosure would, based on the advise of such party’s counsel, result in a waiver of attorney-client privilege, work product doctrine or any other applicable privilege applicable to such information or (iii) the disclosure of such information to the other party would violate confidentiality obligations owed to a third party and such confidentiality obligations were in effect prior to the execution and delivery of this Agreement. The parties hereto shall hold any information obtained pursuant to this Section 7.05 in confidence to the extent set forth in accordance, and such information shall otherwise be subject to, the provisions of the NDA, which shall continue in full force and effect. Any investigation pursuant to this Section 7.05 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the other party.

Section 7.06. Notices of Certain Events. Each of Siebel and Oracle shall promptly after it obtains Knowledge of any of the matters referred to in clauses (a) through (d) of this sentence notify the other of:

(a) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement;

(b) any notice or other communication from any Governmental Entity in connection with the review, clearance or approval of the transactions contemplated by this Agreement;

(c) any Proceeding commenced or threatened against, relating to or involving or otherwise affecting Siebel or any of its Subsidiaries or Oracle and any of its Subsidiaries, as the case may be, that, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to Sections 4.12, 4.13, 4.15(e), 4.16(f), 4.17(a), 4.19(a)(i), 4.20(b) and 5.07, as the case may be, or that relate to the consummation of the transactions contemplated by this Agreement; and

(b) Each of Parent, Oracle and Siebel shall use its reasonable best efforts to obtain the opinions referred to in 8.02(d) and 8.03(b), respectively, including by executing letters of representation substantially in the form of Exhibits A, B and C hereto.

Siebel shall use its reasonable best efforts to obtain a written agreement from each Person who is an affiliate of Siebel as soon as practicable and, in any event, at least 10 days prior to the Effective Time, substantially in the form of Exhibit D hereto.

Section 7.09. Section 16 Matters. Prior to the Effective Time, Oracle and Siebel shall take all such steps as may be required to cause any dispositions of Siebel Stock or Oracle Stock (including derivative securities with

respect to Siebel Stock or Oracle Stock) or acquisitions of Parent Stock (including derivative securities with respect to Parent Stock) resulting from the transactions contemplated by Article 3 hereof by each individual who is subject to the reporting requirements of Section 16(a) of the 1934 Act with respect to Oracle and Siebel or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the 1934 Act.

Section 7.10. Siebel Director and Officer Liability.

(a) (i) All rights, including rights to indemnification, advancement of expenses and exculpation, existing in favor of those Persons who are present or former directors and officers of Siebel as of the date of this Agreement and any other Person who becomes an officer or director of Siebel prior to the Closing (such Persons collectively, the “Siebel Indemnified Persons”) for their acts and omissions as directors and officers of Siebel occurring prior to the Effective Time, as provided in Siebel’s certificate of incorporation and bylaws (each as in effect as of the date of this Agreement) and as provided in any existing indemnification agreements between Siebel and said Siebel Indemnified Persons (as in effect as of the date of this Agreement and identified in Schedule 7.10(a) of Siebel Disclosure Schedule) or any new indemnification agreements that are substantially similar to such existing indemnification agreements shall survive the Mergers and Parent shall cause all such indemnification obligations to be observed by the Siebel Surviving Corporation to the fullest extent permitted by DGCL.

(ii) Without limiting the generality or the effect of the prior sentence, from and after the Effective Time, Parent shall cause the Siebel Surviving Corporation and its Subsidiaries to, and the Siebel Surviving Corporation and its Subsidiaries shall, (a) indemnify and hold harmless the Siebel Indemnified Persons to the fullest extent permitted (whether by the DGCL, by any other applicable Laws, under Siebel’s certificate of incorporation or bylaws in effect on the date hereof, in any indemnification agreement as in effect on the date hereof (or entered into after the date hereof and prior to the Closing as long as the form of such indemnification agreement is substantially the same as the form previously disclosed to Parent) or otherwise) and (b) fulfill and honor in all respects the obligations of Siebel and its Subsidiaries to the Siebel Indemnified Persons pursuant to (i) any indemnification agreement as in effect on the date hereof (or entered into after the date hereof and prior to the Closing as long as the form of such indemnification agreement is substantially the same as the form previously disclosed to Parent), and (ii) any indemnification, expense advancement and exculpation provisions set forth in the certificate of incorporation, bylaws or other charter or organizational documents of Siebel or any of its Subsidiaries as in effect on the date of this Agreement.

(b) From the Effective Time until the sixth anniversary of the Effective Time, Parent shall cause the Siebel Surviving Corporation to maintain in effect, for the benefit of the Siebel Indemnified Persons with respect to their acts and omissions as directors and officers of the Company occurring prior to the Effective Time, the existing policy of directors’ and officers’ liability insurance maintained by Siebel as of the date of this Agreement in the form delivered by Siebel to Parent prior to the date of this Agreement (the “Existing D&O Policy”), if directors’ and officers’ liability insurance coverage is available for Parent’s directors and officers; provided, however, that: (i) the Siebel Surviving Corporation may substitute for the Existing D&O Policy a policy or policies of comparable coverage; and (ii) the Siebel Surviving Corporation shall not be required to pay annual premiums for the Existing D&O Policy (or for any substitute policies) in excess of 200% of the annual premium paid by Siebel with respect to the Existing D&O Policy (the “Maximum Premium”), which amount Siebel has disclosed to Oracle prior to the date hereof. In the event any future annual premiums for the Existing D&O Policy (or any substitute policies) exceed the Maximum Premium, the Siebel Surviving Corporation shall be entitled to reduce the amount of coverage of the Existing D&O Policy (or any substitute policies) to the greatest amount of coverage reasonably procurable for a premium equal to the Maximum Premium.

(c) If Parent, the Siebel 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 or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and

assigns of Parent or the Siebel Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 7.10.

(d) The rights of each Siebel Indemnified Person under this Section 7.10 shall be in addition to any rights such Person may have under the certificate of incorporation or bylaws of Siebel or any of its Subsidiaries, or under the DGCL or any other applicable Laws or under any agreement of any Siebel Indemnified Person with Siebel or any of its Subsidiaries. These rights shall survive consummation of the Mergers and are intended to benefit, and shall be enforceable by, each Siebel Indemnified Person.

Section 7.11. Employee Benefits.

(a) Siebel ESPP. Siebel shall take all action that is necessary to (i) cause the exercise of each outstanding purchase right under Siebel Employee Stock Purchase Plan (the “Siebel ESPP”) no less than five Business Days prior to the Effective Time; (ii) provide that no further purchase period or offering period shall commence under the Siebel ESPP following the date outstanding purchase rights under the Siebel ESPP are exercised in accordance with clause (i) on this sentence; and (iii) terminate the Siebel ESPP immediately prior to and effective as of the Effective Time.

(b) 401(k) Plans. Effective as of the day immediately preceding the Effective Time, if requested in writing by Parent at least 10 business days prior to the Effective Time, Siebel shall terminate any and all 401(k) plans sponsored or maintained by Siebel and shall provide Parent evidence that each of Siebel’s 401(k) plans has been terminated pursuant to resolutions of the Board of Directors of Siebel.

(c) Form S-8. As promptly as practicable but no later than 15 Business Days after the Effective Time, Parent shall file with the SEC a registration statement on Form S-8 covering the sale of Parent Stock issuable pursuant to outstanding Siebel Options and Restricted Stock Awards assumed by Parent pursuant to the terms hereof, and Parent shall use reasonable efforts to maintain the effectiveness of such registration statement so long as any assumed Siebel Options remain outstanding. Siebel will cooperate and reasonably assist Parent in the preparation of such registration statement.

(d) Employee Information. Prior to the Effective Time, Siebel shall provide to Oracle a current schedule in the form maintained by Siebel’s human resources or stock administration department for internal record keeping purposes that identifies as of the Effective Time with respect to each holder of Siebel Options and Siebel Restricted Stock Awards with reasonable accuracy and detail, (i) the name of the holder, (ii) the total number of shares subject to such award, (iii) the Employee Plan under which such award was issued, (iv) the exercise (or purchase price of such award, if applicable), (v) the extent to which such award is vested as the Effective Time, (vi) the vesting schedule of such award, (vii) the grant date of such award, and (viii) the expiration date of such award.

Section 7.12. Nasdaq Listing. Parent and Oracle shall use their respective reasonable best efforts to cause the shares of Parent Stock to be issued in connection with the Mergers and the shares of Parent Stock to be reserved for issuance upon exercise of options to purchase Parent Stock (“Parent Options”) to be approved for listing on the Nasdaq, subject to official notice of issuance, prior to the Effective Time.

Section 7.13. Dividends. (a) After the date of this Agreement, Oracle and Siebel shall use their reasonable best efforts to develop and agree on a plan for cash payments, prior to the earlier of (a) the Closing Date and (b) December 31, 2005, by the foreign Subsidiaries of Siebel to Siebel or its U.S. Subsidiaries that (x) constitute dividends for U.S. federal income tax purposes and (y) are intended to qualify for the temporary dividends received deduction under Section 965(a)(1) of the Code (each such dividend, a “Section 965 Dividend”). The parties agree that such plan shall maximize, to the extent commercially practicable, the amount of Section 965 Dividends. In the event that Siebel and Oracle reach agreement on all or any aspects of such a plan (an “Agreed Plan”), Siebel shall timely take all actions reasonably necessary to implement such Agreed Plan, including but not limited to the payment of all Section 965 Dividends contemplated by the Agreed Plan, making any necessary

election on any Tax Return and obtaining approval of a plan providing for the reinvestment of each Section 965 Dividend in the United States for a permitted purpose. For the avoidance of doubt, Oracle acknowledges that nothing in this Section 7.13(a) shall obligate Siebel to agree on a plan that would be reasonably likely to have an adverse consequence to Siebel and its Subsidiaries in any material respect in the event the Mergers do not occur.

(b) In the event that Siebel and Oracle are unable to reach agreement on all or any aspects of such a plan, Oracle shall provide to Siebel in writing a proposed plan for the payment of Section 965 Dividends that are not part of an Agreed Plan (the “Oracle Proposed Plan”). Upon the written request of Oracle, Siebel shall (i) prior to the satisfaction of the conditions set forth in Sections 8.01 and 8.03 (the “Specified Conditions”), use its reasonable best efforts to take all preparatory actions or steps contemplated by the Oracle Proposed Plan other than such actions or steps that Siebel reasonably believes would impose material costs on or other material detriment to Siebel or any of its Subsidiaries that Siebel and its Subsidiaries would not otherwise incur in connection with the payment of Section 965 Dividends, and (b) if the Specified Conditions are satisfied on or before December 15, 2005, use its reasonable best efforts to take the remaining actions or steps contemplated by the Oracle Proposed Plan, including the payment of all Section 965 Dividends contemplated by the Oracle Proposed Plan, as promptly as possible after the satisfaction of such Specified Conditions, and timely take all actions reasonably necessary to qualify such Section 965 Dividends for the temporary dividends received deduction under Section 965(a)(1) of the Code, including but not limited to making any necessary election on any Tax Return and obtaining approval of a plan providing for the reinvestment of each Section 965 Dividend in the United States for a permitted purpose.

(c) Siebel shall not cause or permit any of its foreign Subsidiaries to pay any Section 965 Dividend that is not part of an Agreed Plan or an Oracle Proposed Plan, provided that, if the Specified Condition have not been satisfied on or before December 15, 2005, with the written consent of Oracle (not to be unreasonably withheld or delayed), Siebel shall be permitted to cause or permit one or more of its foreign Subsidiaries to pay a Section 965 Dividend that is not part of an Agreed Plan or an Oracle Proposed Plan, and shall timely take all actions reasonably necessary to qualify such Section 965 Dividends for the temporary dividends received deduction under Section 965(a)(1) of the Code, including but not limited to making any necessary election on any Tax Return and obtaining approval of a plan providing for the reinvestment of each Section 965 Dividend in the United States for a permitted purpose.

(g) by Siebel if at any time after the date of this Agreement, any Governmental Entity initiates any suit, litigation, arbitration or court or administrative proceeding, obtains any Judgment or obtains any injunction with respect to either of the Mergers, and Oracle fails to use reasonable best efforts to defend against such suit, litigation, arbitration or court or administrative proceeding, appeal such Judgment or contest any such injunction.
