AGREEMENT AND PLAN OF MERGER, dated as of October 26, 2003 (this “Agreement”), among Anthem, Inc., an Indiana corporation (“Purchaser”), Anthem Holding Corp., an Indiana corporation and a direct wholly owned subsidiary of Purchaser (“Merger Sub”), and WellPoint Health Networks Inc., a Delaware corporation (“Company”).

WITNESSETH:

WHEREAS, the respective Boards of Directors (as defined in Section 8.13(d)) of Purchaser and Company deem it advisable and in the best interests of each corporation and its shareholders and stockholders, respectively, that Purchaser and Company engage in a business combination in order to advance the long-term strategic business interests of Purchaser and Company;

WHEREAS, the combination of Purchaser and Company shall be effected by the terms of this Agreement through a merger as outlined below;

WHEREAS, in furtherance thereof, the respective Boards of Directors of Purchaser, Merger Sub and Company have adopted or approved this Agreement, pursuant to which Company will be merged with and into Merger Sub on the terms and subject to the conditions set forth in this Agreement (the “Merger”), with each share of common stock, $0.01 par value, of Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (as defined in Section 1.3) (other than (i) Company Treasury Shares (as defined in Section 1.8(a)), (ii) shares of Company Common Stock owned by Purchaser or Merger Sub, (iii) shares of Company Common Stock that are owned by stockholders (“Dissenting Stockholders”) who shall not have voted in favor of the Merger and who shall have properly demanded in writing appraisal for such shares (“Dissenting Shares”) pursuant to Section 262 of the Delaware General Corporation Law (“DGCL”) and (iv) Subsidiary Held Stock (as defined in Section 1.8(d)) being converted into the right to receive (i) $23.80 cash, without interest, and (ii) one share of common stock, par value $0.01 per share, of Purchaser (“Purchaser Common Stock”);

WHEREAS, in furtherance thereof, the Board of Directors of Purchaser has adopted and approved resolutions to amend the (i) articles of incorporation of Purchaser and (ii) bylaws of Purchaser, in each case such amendments to be effective as of the Effective Time;

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Treasury regulations promulgated thereunder and that this Agreement shall constitute a plan of reorganization within the meaning of Sections 354 and 361 of the Code; and

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

THE MERGER

1.1. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL and the Indiana Business Corporation Law (“IBCL”), Company shall be merged with and into Merger Sub at the Effective Time (as defined in Section 1.3). Upon consummation of the Merger, the separate corporate existence of Company shall cease and Merger Sub shall continue as the surviving corporation (the “Surviving Corporation”).

1.2. Closing. Subject to the terms and conditions hereof, the closing of the Merger and the transactions contemplated by this Agreement (the “Closing”) will take place on the second Business Day (as defined in Section 8.13(e)) after the satisfaction or waiver (subject to applicable law) of the conditions set forth in Article VI (other than any such conditions which by their terms cannot be satisfied until the Closing Date, which shall be required to be so satisfied or waived (subject to applicable law) on the Closing Date), unless another time or date is agreed to in writing by the parties hereto (the actual time and date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of Baker & Daniels, 300 North Meridian Street, Suite 2700, Indianapolis, Indiana, unless another place is agreed to in writing by the parties hereto.

1.3. Effective Time. At the Closing, the parties shall file a certificate of merger and articles of merger (together, the “Articles of Merger”) in such form as is required by and executed in accordance with the respective relevant provisions of the DGCL and the IBCL. The Merger shall become effective at such time the Articles of Merger are duly filed with the Secretary of State of the State of Delaware and the Secretary of State of the State of Indiana, as applicable, or at such subsequent time as Purchaser and Company shall agree and as shall be specified in each of the Articles of Merger (the date and time the Merger becomes effective being the “Effective Time”).

1.4. Effects of the Merger. At and after the Effective Time, the Merger will have the effects set forth in the DGCL and the IBCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of Company and Merger Sub shall be vested in the Surviving Corporation, and all debts, liabilities and duties of Company and Merger Sub shall be the debts, liabilities and duties of the Surviving Corporation.

1.5. Articles of Incorporation. At the Effective Time and without any further action on the part of Company or Merger Sub, the articles of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the articles of incorporation of the Surviving Corporation, until thereafter changed or amended as provided therein or by applicable law.

1.6. Bylaws. At the Effective Time and without any further action on the part of Company and Merger Sub, the bylaws of Merger Sub shall be the bylaws of the Surviving Corporation, until thereafter changed or amended or repealed as provided therein, in the articles of incorporation of the Surviving Corporation or by applicable law.

1.7. Directors and Officers of Surviving Corporation. The directors of Merger Sub as of the Effective Time shall serve as directors of the Surviving Corporation until the earlier of their death, resignation or removal or otherwise ceasing to be a director or until their respective successors are duly elected or appointed and qualified. The persons designated by the Board of Directors of Merger Sub prior to the Effective Time shall serve as the officers of the Surviving Corporation, until the earlier of their death, resignation or removal or otherwise ceasing to be an officer or until their respective successors are duly elected or appointed and qualified.

1.8. Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock:

(a) All shares of Company Common Stock that are held by Company as treasury stock (the “Company Treasury Shares”) or by Purchaser or Merger Sub shall be canceled and shall cease to exist and no cash, Purchaser Common Stock or other consideration shall be delivered in exchange therefor.

(b) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) Company Treasury Shares, (ii) shares of Company Common Stock owned by Purchaser or Merger Sub, (iii) Dissenting Shares and (iv) Subsidiary Held Stock) shall be converted at the Effective Time into the right to receive (x) $23.80 in cash, without interest (the “Cash Consideration”), and (y) one share of Purchaser Common Stock (the “Stock Consideration” and, together with the Cash Consideration, the “Merger Consideration”). Upon such conversion, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each Company Certificate (as defined in Section 1.10) shall thereafter represent the right to receive the Merger Consideration, cash for fractional shares in accordance with Section 2.5 and any dividends or other distributions pursuant to Section 2.3 upon the surrender of the Company Certificate in accordance with the terms hereof. Any Dissenting Shares shall thereafter represent only the right to receive the payments set forth in Section 1.9.

(c) Each share of common stock, par value $0.01, of Merger Sub outstanding immediately prior to the Effective Time shall remain outstanding and unchanged following the Effective Time as shares of the Surviving Corporation.

(d) Each share of Company Common Stock held by a Subsidiary of Company or a Subsidiary (other than Merger Sub) of Purchaser (“Subsidiary Held Stock”) shall be converted into the right to receive a number of shares of Purchaser Common Stock equal to the product of one multiplied by the Option Exchange Ratio (as defined in Section 1.11) (“Subsidiary Stock Consideration”) and no Cash Consideration. Upon such conversion, all such shares of Subsidiary Held Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each certificate which immediately prior to the Effective Time represented any such shares of Subsidiary Held Stock (“Subsidiary Held Certificate”) shall thereafter represent the right to receive the Subsidiary Stock Consideration and cash for fractional shares in accordance with Section 2.5 upon the surrender of such certificate in accordance with the terms hereof.

1.9. Dissenter’s Rights. No Dissenting Stockholder shall be entitled to the Merger Consideration or cash in lieu of fractional shares of Purchaser Common Stock or any dividends or other distributions pursuant to this Article I unless and until the holder thereof shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal of such shares of Company Common Stock held by such holder under Section 262 of the DGCL, and any Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL with respect to shares of Company Common Stock owned by such Dissenting Stockholder. If any Person (as defined in Section 8.13(l)) who otherwise would be deemed a Dissenting Stockholder shall have failed to properly perfect or shall have effectively withdrawn or lost the right to dissent with respect to any shares of Company Common Stock, such shares of Company Common Stock shall thereupon be treated as though such shares of Company Common Stock had been converted into the right to receive the Merger Consideration pursuant to Section 1.8 hereof. Company shall give Purchaser (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands and any other instruments served pursuant to applicable law received by Company relating to stockholders’ rights of appraisal and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands for appraisal under the DGCL. Company shall not, except with the prior written consent of Purchaser (which consent shall not be unreasonably withheld), voluntarily make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal of any such demands.

1.10. Exchange Agent. Prior to the Effective Time, Purchaser shall appoint EquiServe Trust Company, N.A., or another bank or trust company reasonably satisfactory to Company, as exchange agent (the “Exchange Agent”) for the purpose of exchanging certificates which immediately prior to the Effective Time evidenced shares of Company Common Stock (the “Company Certificates”) for the Merger Consideration.

1.11. Company Stock Options and Other Stock Awards.

(a) Purchaser and Company shall take all action reasonably necessary so that each employee or director stock option exercisable for shares of Company Common Stock (the “Company Stock Options”) outstanding immediately prior to the Effective Time shall be converted automatically at the Effective Time into an option to purchase a number of shares of Purchaser Common Stock (a “Converted Option”) equal to the product of the number of shares of Company Common Stock subject to such Company Stock Option multiplied by the Option Exchange Ratio; provided that any fractional share resulting from such multiplication shall be rounded to the nearest whole share. The “Option Exchange Ratio” shall mean the sum of (i) one plus (ii) a fraction the numerator of which is 23.80 and the denominator of which is the closing trading price of Purchaser Common Stock on the New York Stock Exchange Inc. (“NYSE”), as reported in the Wall Street Journal, Eastern Edition (or such other source as the parties shall agree in writing), on the Business Day prior to the Effective Time. The terms and conditions of the Converted Options shall otherwise remain the same as the terms and conditions of the Company Stock Options (including the existing “option reload” feature), except that the exercise price per share of each Converted Option shall equal the exercise price per share of such Company Stock Option divided by the Option Exchange Ratio; provided that such exercise price shall be rounded to the nearest whole cent. Notwithstanding the

foregoing, each Company Stock Option which is intended to be an “incentive stock option” (as defined under Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code.

(b) All shares of restricted Company Common Stock (the “Company Restricted Stock Awards”) held by employees or directors of the Company or its Subsidiaries and outstanding immediately prior to the Effective Time shall be treated in the same manner as all other shares of Company Common Stock outstanding immediately prior to the Effective Time pursuant to Section 1.8 of this Agreement (the “Converted Restricted Stock Awards”); provided, however, that the Merger Consideration received by each holder in exchange for the holder’s Company Restricted Stock Awards pursuant to Section 1.8 of this Agreement shall be subject to the terms and conditions (including vesting schedules) applicable to such Company Restricted Stock Awards under the plan and award agreements pursuant to which such Company Restricted Stock Awards were granted as in effect prior to the Effective Time; provided, further, however, that the per-share Cash Consideration portion of such Merger Consideration shall be held by the Surviving Corporation in accounts for such persons until vested, and invested as directed by the employee or director among the investment options available from time to time under the WellPoint Comprehensive Executive Non-Qualified Retirement Plan or WellPoint Board of Directors Deferred Compensation Plan, as applicable.

For purposes hereof, the Company Restricted Stock Awards, together with all other awards of shares of Company Common Stock subject to vesting or future issuance under any Company Stock Plan, including without limitation restricted stock units and deferred stock awards (but not including Company Stock Options or the Company ESPP), shall be referred to as the “Other Stock Awards.”

(c) Purchaser and Company shall take all action reasonably necessary so that all Other Stock Awards other than Company Restricted Stock Awards held by employees or directors of the Company or its Subsidiaries immediately prior to the Effective Time shall be converted automatically at the Effective Time into a right or award with respect to a number of shares of Purchaser Common Stock (a “Converted Other Stock Award”) equal to the product of the number of shares of Company Common Stock subject to such Other Stock Award multiplied by the Option Exchange Ratio; provided, that any fractional shares resulting from such multiplication shall be rounded to the nearest whole share. The terms and conditions of the Converted Other Stock Award shall otherwise remain the same as the terms and conditions (including vesting schedules) applicable to the Other Stock Awards under the plan and award agreements pursuant to which such Other Stock Awards were granted as in effect immediately prior to the Effective Time.

(d) Purchaser shall, as of the Effective Time, assume the obligations of Company under all plans and agreements pursuant to which a Company Stock Option or Other Stock Award has been issued (the “Company Stock Plans”) and shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Purchaser Common Stock for delivery upon exercise of the Converted Options or future issuance under the Converted Other Stock Awards. Purchaser shall use its reasonable

best efforts to cause the registration of the shares of Purchaser Common Stock subject to the Converted Options, Converted Other Stock Awards or Converted Restricted Stock Awards to become effective as part of a registration statement on Form S-8 or Form S-3 as the case may be, or any successor or other appropriate forms, with respect to the shares of Purchaser Common Stock subject to the Converted Options, Converted Other Stock Awards or Converted Restricted Stock Awards no later than the Effective Time; and, thereafter, Purchaser shall deliver to holders of Converted Options, Converted Other Stock Awards or Converted Restricted Stock Awards any applicable prospectus and shall maintain the effectiveness of such registration statement or registration statements, including the current status of any related prospectus, for so long as the Converted Options, Converted Other Stock Awards or Converted Restricted Stock Awards remain outstanding.

(e) Purchaser and Company shall take all such steps within their control as may be required to cause the transactions contemplated by this Section 1.11 and any other deemed dispositions of Company equity securities (including derivative securities) or deemed acquisitions of Purchaser equity securities (including derivative securities) in connection with this Agreement by each individual who (i) is a director or officer of Company or (ii) at the Effective Time will become a director or officer of Purchaser, to become exempt from liability under Section 16(b) of the Securities Exchange Act of 1934 (as amended and including all rules and regulations promulgated thereunder, the “Exchange Act”) pursuant to Rule 16b-3 thereunder.

(f) As soon as practicable after the Effective Time, Purchaser shall deliver or cause to be delivered to each holder of Converted Options, Converted Other Stock Awards or Converted Restricted Stock Awards an appropriate notice setting forth such holder’s rights pursuant to any Company Stock Plans, after giving effect to the transactions hereunder.

1.12. Certain Adjustments. If, between the date of this Agreement and the Effective Time, the outstanding Purchaser Common Stock or Company Common Stock shall have been changed into a different number of shares or different class by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares or a stock dividend or dividend payable in any other securities shall be declared with a record date within such period, or any similar event shall have occurred, the Merger Consideration, Subsidiary Stock Consideration and the Option Exchange Ratio shall be appropriately adjusted to provide to the holders of Company Common Stock, Company Stock Options and Other Stock Awards the same economic effect as contemplated by this Agreement prior to such event.

1.13. Corporate Governance.

(a) Board of Directors.

(i) Composition. At the Effective Time, Purchaser’s Board of Directors will comprise 20 directors, to consist of 12 current members of Purchaser’s Board of Directors (including the current Chairman, President and Chief Executive Officer of Purchaser, Larry C. Glasscock) designated by

Purchaser before the mailing of the Joint Proxy Statement (as defined in Section 3.1(e)(i)), at least 7 of whom must be “independent” under the rules of the NYSE and the SEC with respect to Purchaser (the “Former Purchaser Directors”), and 8 current members of Company’s Board of Directors (including the current Chairman and Chief Executive Officer of Company, Leonard D. Schaeffer) designated by Company before the mailing of the Joint Proxy Statement, at least 5 of whom must be “independent” under the rules of the NYSE and the SEC with respect to Purchaser (the “Former Company Directors”). If any Former Purchaser Director or Former Company Director designated shall be unable or unwilling to serve as a director at the Effective Time, the party which designated such individual as indicated above shall designate another individual reasonably acceptable to the Governance Committee of Purchaser (the “Governance Committee”) to serve in such individual’s place. The Former Purchaser Directors and Former Company Directors who are designated will be split such that two of the three classes of Purchaser directors will be comprised of four Former Purchaser Directors and three Former Company Directors and one of the three classes of Purchaser Directors will be comprised of four Former Purchaser Directors and two Former Company Directors. Prior to the mailing of the Joint Proxy Statement, each of Purchaser and Company will designate in writing the class to which each Former Purchaser Director and each Former Company Director designated by Purchaser and Company, respectively, is to be assigned. The members of Purchaser’s Board of Directors as of the Effective Time will serve as directors until their respective successors are duly elected and qualified in accordance with Purchaser’s articles of incorporation, Purchaser’s bylaws and applicable law unless he or she earlier resigns, retires, is removed or is unable to serve.

2.1. Exchange Fund. At or prior to the Effective Time, Purchaser shall deposit with the Exchange Agent, in trust for the benefit of holders of shares of Company Common Stock, (i) certificates representing the Purchaser Common Stock issuable pursuant to Section 1.8 (or otherwise shall make shares of Purchaser Common Stock available for such issuance) and (ii) cash sufficient to pay the aggregate Cash Consideration to be paid in the Merger, cash for fractional shares in accordance with Section 2.5 and any dividends or other distributions pursuant to Section 2.3. Purchaser shall make available to the Exchange Agent, from time to time as needed, additional cash sufficient to pay cash in lieu of fractional shares pursuant to Section 2.5 and any dividends and other distributions pursuant to Section 2.3. Any cash and certificates of Purchaser Common Stock deposited with the Exchange Agent (or shares of Purchaser Common Stock otherwise made available to the Exchange Agent pursuant to this Section 2.1) shall hereinafter be referred to as the “Exchange Fund.”

2.2. Exchange Procedures. Promptly, but in any event within ten Business Days after the Effective Time, Purchaser shall cause the Exchange Agent to mail to each holder of record of a Company Certificate (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon delivery of the Company Certificates to the Exchange Agent, and which letter shall be in customary form and (ii) instructions for effecting the surrender of such Company Certificates in exchange for the Merger Consideration. Upon surrender of a Company Certificate to the Exchange Agent together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Company Certificate shall be entitled to receive in exchange therefor (A) the number of shares of Purchaser Common Stock that such holder has the right to receive pursuant to Section 1.8 (which shall be in uncertificated book-entry form unless a physical certificate is requested) and (B) a check in the amount of the aggregate Cash Consideration that such holder has the right to receive pursuant to Section 1.8 and for the cash that such holder has the right to receive pursuant to the provisions of this Article II, including cash in lieu of any fractional shares of Purchaser Common Stock pursuant to Section 2.5 and dividends and other distributions pursuant to Section 2.3.

2.3. Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made with respect to shares of Purchaser Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Certificate with respect to the shares of Purchaser Common Stock that such holder would be entitled to receive upon surrender of such Company Certificate until such holder shall surrender such Company Certificate in accordance with Section 2.2. Subject to the effect of applicable laws, following surrender of any such Company Certificate, there shall be paid to such holder of shares of Purchaser Common Stock issuable in exchange therefor, without interest, (a) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date prior to such surrender payable with respect to such shares of Purchaser Common Stock and (b) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such shares of Purchaser Common Stock.

All shares of Purchaser Common Stock issued and cash paid upon conversion of shares of Company Common Stock or Subsidiary Held Stock in accordance with the terms of Article I and this Article II (including any cash paid pursuant to Section 2.3 or 2.5) shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the shares of Company Common Stock or Subsidiary Held Stock. Until surrendered as contemplated by this Article II, each Company Certificate or Subsidiary Held Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration or the Subsidiary Stock Consideration (and any cash to be paid pursuant to Section 2.3 or 2.5), or the right to the payment provided by Section 262 of the DGCL pursuant to Section 1.9, as applicable.

2.5. No Fractional Shares of Purchaser Common Stock.

(a) No certificates or scrip representing fractional shares of Purchaser Common Stock or book-entry credit of the same shall be issued upon the surrender for exchange of Company Certificates and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a shareholder of Purchaser or a holder of shares of Purchaser Common Stock.

(b) Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock or Subsidiary Held Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Purchaser Common Stock (after taking into account all Company Certificates and Subsidiary Held Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to the product of (i) such fractional part of a share of Purchaser Common Stock multiplied by (ii) the closing price for a share of Purchaser Common Stock on the NYSE Composite Transactions Tape on the date of the Effective Time or, if such date is not a Business Day, the Business Day immediately before the date on which the Effective Time occurs. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent shall so notify Purchaser, and Purchaser shall cause the Surviving Corporation to deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms hereof.

2.6. Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Certificates twelve months after the Effective Time shall be delivered to Purchaser or otherwise on the instruction of Purchaser and any holders of the Company Certificates who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation and Purchaser for the Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby to which such holders are entitled pursuant to Section 1.8 and Section 2.2, any cash in lieu of fractional shares of Purchaser Common Stock to which such holders are entitled pursuant to Section 2.5 and any dividends or distributions with respect to shares of Purchaser Common Stock to which such holders are entitled pursuant to Section 2.3.

2.7. No Liability. None of Purchaser, Merger Sub, Company, the Surviving Corporation or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

2.8. Investment of the Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Purchaser on a daily basis, or as otherwise agreed to by Purchaser and the Exchange Agent. Any interest and other income resulting from such investments shall promptly be paid to Purchaser, or as otherwise agreed to by Purchaser and the Exchange Agent.

2.9. Lost Certificates. If any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Company Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Company Certificate the applicable Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby, any cash in lieu of fractional shares of Purchaser

Common Stock, and unpaid dividends and distributions on shares of Purchaser Common Stock deliverable in respect thereof, in each case, pursuant to this Agreement.

2.10. Withholding Rights. Each of the Surviving Corporation and Purchaser shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and Treasury regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or Purchaser, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or Purchaser, as the case may be, and such amounts shall be delivered by the Surviving Corporation or Purchaser, as the case may be, to the applicable taxing authority.

2.11. Further Assurances. At and after the Effective Time, the officers and managers of the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of Company or Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Company or 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.

2.12. Stock Transfer Books. The stock transfer books of Company shall be closed immediately upon the Effective Time and there shall be no further registration of transfers of shares of Company Common Stock thereafter on the records of Company. On or after the Effective Time, any Company Certificate presented to the Exchange Agent or Purchaser for any reason shall be converted into the Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby, any cash in lieu of fractional shares of Purchaser Common Stock to which the holders thereof are entitled pursuant to Section 2.5 and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.3.

ARTICLE V

ADDITIONAL AGREEMENTS

5.1. Preparation of Form S-4 and the Joint Proxy Statement; Stockholders/ Shareholders Meetings.

(a) Promptly following the date of this Agreement, Purchaser and Company shall prepare and file with the SEC the Joint Proxy Statement, and Purchaser shall prepare and file with the SEC the Form S-4, in which the Joint Proxy Statement will be included as a prospectus. Each of Purchaser and Company shall use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing. Each of Purchaser and Company will use its reasonable best efforts to cause the Joint Proxy Statement to be mailed to its shareholders and stockholders, respectively, as promptly as practicable after the Form S-4 is declared effective under the Securities Act. Purchaser shall also take any action (other than qualifying to do business in any jurisdiction in which it is not now so qualified) required to be taken under any applicable state securities law in connection with the Share Issuance, and Company shall furnish all information concerning Company and the holders of Company Common Stock and rights to acquire Company Common Stock pursuant to the Company Stock Plans as may be reasonably required in connection with any such action. Each of Purchaser and Company shall furnish all information concerning itself and its Subsidiaries to the other as may be reasonably requested in connection with any such action and the preparation, filing and distribution of the Form S-4 and the preparation, filing and distribution of the Joint Proxy Statement. Purchaser and Company each agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it or its Subsidiaries for inclusion or incorporation by reference in (i) the Form S-4 will, at the time the Form S-4 becomes effective under the Securities Act, 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, in light of the circumstances under which they were made, not misleading, and (ii) the Joint Proxy Statement and any amendment or supplement thereto will, at the date of mailing to shareholders or stockholders, as applicable, and at the times of the meetings of shareholders or stockholders of Purchaser and Company, as applicable, to be held in connection with the Share Issuance and Articles Amendment or the Merger, as applicable, 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. Each of Purchaser, Merger Sub and Company agrees to promptly correct any information provided by it for use in the Form S-4 or the Joint Proxy Statement that shall have become false or misleading. Purchaser and Company will cause the Form S-4 and the Joint Proxy Statement to comply as to form in all material respects with the applicable provisions of the Securities Act and the rules and regulations thereunder.

(b) Company, acting through its Board of Directors, shall, subject to and in accordance with its certificate of incorporation and bylaws, promptly and duly call, give notice of, convene and hold as soon as practicable following the date upon which the Form S-4 becomes effective a meeting of the holders of Company Common Stock (the “Company Stockholders Meeting”) for the purpose of voting to adopt this Agreement, and except as otherwise provided in the following sentence, (i) shall recommend adoption of this Agreement by the stockholders of Company (the “Company Recommendation”) and include in the Joint Proxy Statement such Company Recommendation, (ii) shall use its reasonable best efforts to solicit and obtain such adoption and (iii) shall not withdraw, amend or modify (or publicly propose to or publicly state that it intends to withdraw, amend or modify) in any manner adverse to Purchaser such recommendation (collectively, a “Change in Company Recommendation”). In the event that prior to the adoption of this Agreement by the Company stockholders, the Board of Directors of Company determines in good faith by resolution duly adopted after consultation with its outside counsel that such action is reasonably likely to be required in order for the directors to comply with their respective fiduciary duties under Delaware law, the Board of Directors of Company may effect a Change in Company Recommendation; provided, however, that if the Change in Company Recommendation is in respect of an Alternative Transaction, the Board of Directors of Company may effect a Change in Company Recommendation only if Company shall have complied in all material respects with the applicable provisions of Section 5.5 with respect thereto and if the Board of Directors of Company has determined in good faith that such Alternative Transaction is a Superior Proposal; provided, further, however, that before effecting a Change in Company Recommendation, it gives Purchaser five business days’ prior written notice of its intention to do so (unless at the time such notice is otherwise required to be given there are less than five business days prior to the Company Stockholders Meeting, in which case Company shall provide as much notice as is reasonably practicable) and during such time, Company, if requested by Purchaser, shall have engaged in good faith negotiations to amend this Agreement (including by making its officers and its financial and legal advisors reasonably available to negotiate) such that the Board of Directors of Company may continue to recommend the adoption of this Agreement. The parties agree that nothing in this Section 5.1(b) shall in any way limit or otherwise affect Purchaser’s right to terminate this Agreement pursuant to Section 7.1(c) at such time as the requirements of such subsection have been met. Any such Change in Company Recommendation shall not (x) change the approval of this Agreement or any other approval of the Board of Directors of Company in any respect that would have the effect of causing any state (including Delaware) corporate takeover statute or other similar statute to be applicable to the transactions contemplated hereby, including the Merger, or (y) change the obligation of Company to present this Agreement for adoption at the Company Stockholders Meeting on the earliest practicable date after the Form S-4 becomes effective. Notwithstanding any Change in Company Recommendation, if this Agreement is not otherwise terminated by either Company or Purchaser in accordance with the terms hereof, this Agreement shall be submitted to the stockholders of Company at the Company Stockholders Meeting for the purpose of voting on adopting this Agreement, and nothing contained herein, including any rights of Company to take certain actions pursuant to Section 5.5, shall be deemed to relieve Company of such obligation. Nothing

contained in this Agreement shall prohibit Company from taking and disclosing to its stockholders a position contemplated by complying with Rule 14a-9, Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act or from making disclosure of the fact that a proposal for an Alternative Transaction (as defined in Section 8.13(a)) has been made, the identity of the party making the proposal or the material terms of such proposal in the Form S-4 or the Joint Proxy Statement, to the extent disclosure of such facts, identity or terms is advisable under applicable law (and the disclosure of such facts, by itself, shall not be deemed a Change in Company Recommendation or a withdrawal or adverse modification or amendment of its approval of this Agreement).

(c) Purchaser, acting through its Board of Directors, shall, subject to and in accordance with its articles of incorporation and bylaws, promptly and duly call, give notice of, convene and hold as soon as practicable following the date on which the Form S-4 becomes effective, a meeting of the holders of Purchaser Common Stock (the “Purchaser Shareholders Meeting”) for the purpose of voting to approve the Share Issuance and the Articles Amendment. Purchaser shall recommend such approval to its shareholders (the “Purchaser Recommendation”) and use its reasonable best efforts to solicit and obtain such approval. The Board of Directors of Purchaser shall not withhold, withdraw, amend or modify in any manner adverse to Company its recommendation referred to in the preceding sentence (or announce publicly its intention to do so). Nothing contained in this Agreement shall prohibit Purchaser from making any factual disclosure regarding this Agreement, the parties hereto, or any of the transactions contemplated hereby, if such disclosure is advisable under applicable law (and the disclosure of such information, by itself, shall not be deemed a withholding, withdrawal or adverse modification or amendment of its approval or recommendation to its shareholders of the Share Issuance and the Articles Amendment).

(d) During the term of this Agreement, Company shall not take any actions to exempt any Person other than Purchaser and Merger Sub from the threshold restrictions on Company Common Stock ownership or any other antitakeover provision in Company’s certificate of incorporation, or make any state takeover statute (including any Delaware state takeover statute) or similar statute inapplicable to any Alternative Transaction.

(e) During the term of this Agreement, Purchaser shall not take any actions to exempt any Person from the threshold restrictions on Purchaser Common Stock ownership or any other antitakeover provision in Purchaser’s articles of incorporation, or make any state takeover statute (including any Indiana state takeover statute) or similar statute inapplicable to any Alternative Transaction.

(f) Purchaser and Company shall endeavor to hold the Purchaser Shareholders Meeting and the Company Stockholders Meeting as closely together in time as practicable and, to the extent possible, on the same date.

5.3. Access to Information. Upon reasonable notice, each party shall (and shall cause its Subsidiaries to) afford to the officers, employees, accountants, counsel, financial advisors and other representatives of the other party reasonable access during normal business hours, during the period prior to the Effective Time, to such of its properties, books, contracts, commitments, records, officers and employees as the other party may reasonably request and, during such period, such party shall (and shall cause its Subsidiaries to) furnish promptly to the other party (a) a copy of each report, schedule, registration statement and other document filed, published, announced or received by it during such period pursuant to the requirements of Federal or state securities laws, as applicable (other than documents which such party is not permitted to disclose under applicable law), and (b) consistent with its legal obligations, all other information concerning it and its business, properties and personnel as such other party may reasonably request; provided, however, that either party may restrict the foregoing access 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 access to any properties or information. The parties will hold any such information that is non-public in confidence to the extent required by, and in accordance with, the provisions of the Confidentiality Agreement, dated October 8, 2003, between Purchaser and Company (the “Confidentiality Agreement”). Notwithstanding anything in this Agreement or in the Confidentiality Agreement to the contrary, any party to this Agreement (and any employee, representative, or other agent of any party to this Agreement) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure; provided, however, that the preceding sentence shall not permit any party (or any employee, representative or other agent thereof) to disclose any information (i) that is not relevant to an understanding of the U.S. federal income tax treatment of any transaction contemplated by this Agreement, including the identity of Purchaser or Company (or their employees, representatives or agents) or other information that could lead any person to determine such identity or (ii) to the extent required to be kept confidential to comply with any applicable federal or state securities laws. Any investigation by Purchaser or Company shall not affect the representations and warranties of Company or Purchaser, respectively.

5.4. Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each party will use its reasonable best efforts to prepare and file as promptly as practicable all documentation to effect all necessary applications, notices, petitions, filings, tax ruling requests and other documents and to obtain as promptly as practicable all consents, waivers, licenses, orders, registrations, approvals, permits, tax rulings and authorizations necessary or advisable to be obtained from any third party and/or any Governmental Entity in order to consummate the Merger and the other transactions contemplated by this Agreement. Upon the terms and subject to the conditions hereof, each party will use its reasonable best efforts to take, or cause to be taken, all actions, to do, or cause to be done, all things reasonably necessary to satisfy the conditions to Closing set forth herein and to consummate the Merger and the other transactions contemplated by this Agreement. Company and Purchaser shall provide the other party with the opportunity to participate in any meeting or substantive telephone call with any Governmental Entity in respect of any filings, investigations or other inquiry in connection with the transactions contemplated hereby.

(b) In furtherance and not in limitation of the foregoing, each party hereto agrees to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable after the date hereof and to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act. Each of Purchaser and Company shall cooperate in all respects with each other in connection with any filing or submission and in connection with any investigation or other inquiry under the HSR Act.

(c) In furtherance and not in limitation of the foregoing, the parties agree that Purchaser and Company shall each make as promptly as practicable such filings as are required in connection with this Agreement and the transactions contemplated hereby. Purchaser and Company agree that Purchaser shall make the “Form A” and other regulatory filings to be made with the domiciliary insurance regulator of each Subsidiary of Company that is an insurance company or health maintenance organization, the substance of which shall be reasonably agreed between Purchaser and Company and shall, in consultation with Company, coordinate the conduct of any hearing or hearings required in connection with such filings. Purchaser and Company shall, as promptly as practicable after receipt thereof, provide each other with copies of any written comments and advise the other party of any oral comments with respect to the Form A or other regulatory filing from each applicable Governmental Entity. Purchaser and Company shall have the right to participate in any meetings or telephone conferences in which the substance of the Form A and other regulatory filings is discussed. Purchaser and Company will reasonably cooperate with regard to all other regulatory notice filings or approval requests necessary or desirable in connection with the transactions contemplated by this Agreement. Subject to applicable law relating to the sharing of information, Purchaser and Company, as the case may be, shall submit all such filings, requests and hearing testimony, witness lists and other similar materials relating to any hearing to the other for its review prior to filing the substance of each of the foregoing shall be reasonably agreed between Purchaser and Company.

(d) Nothing contained in this Section 5.4 shall be construed as requiring Purchaser or Company to agree to any terms or conditions that would impose (i) any limitations on Purchaser’s or Company’s ownership or operation of all or any portion of their respective, or any of their respective Subsidiaries’, businesses or assets, or to compel Purchaser or Company to dispose of or hold separate all or any portion of their respective, or any of their respective Subsidiaries’, businesses or assets, (ii) any limitations on the ability of Purchaser to acquire or hold or to exercise full rights of ownership of the Company Common Stock, (iii) any obligations on Purchaser or any of its Subsidiaries or Company or any of its Subsidiaries to maintain facilities, operations, places of business, employment levels, products or businesses or (iv) any other obligation, restriction, limitation, qualification or other conditions, which, in the case of any such term or condition described in clauses (i) through (iv) above, would be, individually or in the aggregate with all other such terms and conditions, (A) reasonably likely to have a material and adverse effect on Purchaser and its Subsidiaries, taken as a whole, (B) reasonably likely to have a material and adverse effect on Company and its Subsidiaries, taken as a whole, or (C) reasonably likely to (1) have a material and adverse effect on the expected pro forma financial statements of Purchaser following consummation of the Merger as agreed by Purchaser and Company prior to the date hereof and (2) be materially different in character, degree or scope from terms or conditions generally imposed in connection with such consents, waivers, licenses, orders, registrations, approvals, permits, tax rulings or authorizations (a “Burdensome Term or Condition”). Neither Purchaser nor Company shall agree to any terms or conditions described in clauses (i) through (iv) above without the prior written consent of the other party.

5.5. No Solicitation of Transactions. Each of Purchaser and Company agrees that, during the term of this Agreement, it shall not, and shall cause its respective Subsidiaries and its and its respective Subsidiaries’ directors, officers, employees, agents and representatives (including any investment banker, attorney or accountant retained by it or any of its respective Subsidiaries) not to, directly or indirectly, solicit, initiate, encourage or facilitate, or furnish or disclose non-public information in furtherance of, any inquiries or the making of any proposal with respect to any Alternative Transaction, or negotiate, explore or otherwise engage in discussions with any Person (other than Purchaser, Merger Sub, Company or their respective directors, officers, employees, agents and representatives) with respect to any Alternative Transaction, or approve, endorse, recommend or authorize any Alternative Transaction, or enter into any agreement, arrangement or understanding with respect to any Alternative Transaction or requiring it to abandon, terminate or fail to consummate the Merger or any other transactions contemplated by this Agreement; provided that, at any time prior to the adoption of this Agreement by Company’s stockholders, Company may furnish information to, and negotiate or otherwise engage in discussions with, any party who delivers a bona fide written proposal for an Alternative Transaction which was not solicited or encouraged after the date of this Agreement, if and so long as the Board of Directors of Company determines in good faith by resolution duly adopted after consultation with its outside legal counsel that providing such information or engaging in such negotiations or discussions is reasonably likely to be required in order for the directors to comply with their respective fiduciary duties under Delaware law and determines in good faith that such a proposal is, or is reasonably likely to lead to, a Superior Proposal. Company shall notify Purchaser promptly (but in any event within 24 hours) of such inquiries,

proposals or offers received by, or any such discussions or negotiations sought to be initiated or continued with, any of its representatives, indicating the name of such Person and providing to Purchaser a summary of the material terms of such proposal or offer for an Alternative Transaction. Prior to providing any information or data to, or entering into any negotiations or discussions with, any Person, or making any such recommendation, in connection with a proposal or offer for an Alternative Transaction, Company shall receive from such Person an executed confidentiality agreement containing terms and provisions at least as restrictive as those contained in the Confidentiality Agreement (which shall not preclude discussions or negotiations relating to the proposal or offer from such Person and which shall not contain any exclusivity provision or other term that would restrict, in any manner, Company’s ability to consummate the transactions contemplated by this Agreement). Company agrees that it will keep Purchaser informed, on a prompt basis, of the status and material terms of any such proposals or offers and the status of any material developments in respect of any such discussions or negotiations and that it will deliver to Purchaser a summary of any material changes to any such proposals or offers and all nonpublic information being furnished to such Person. Purchaser agrees that it will keep Company informed, on a prompt basis, of the status and material terms of any proposals or offers for an Alternative Transaction in respect of Purchaser and that it will deliver to Company a summary of any material changes to any such proposals or offers. Company and Purchaser each agree that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Third Parties conducted prior to the date of this Agreement with respect to any Alternative Transaction and will not terminate, amend, modify or waive any provision of any confidentiality or standstill agreement to which it is a party and shall enforce, to the fullest extent permitted under applicable law, the provisions of any such agreement, including, but not limited to, by obtaining injunctions to prevent any breaches of such agreements and to enforce specifically the terms and provisions thereof in any court having jurisdiction. It is understood that participation by Company or its directors, officers, employees, advisors or other representatives in discussions or negotiations in compliance with the provisions of this Section 5.5 shall not be deemed “solicitations” for purposes of this Section and an Alternative Transaction proposal if initially unsolicited in compliance with this Section 5.5 shall continue to be deemed an unsolicited Alternative Transaction proposal notwithstanding changes in such Alternative Transaction proposal as a result of such discussions or negotiations.

5.6. Employee Benefits Matters.

(a) Continuation of Benefits. From the Effective Time until December 31, 2005, the Surviving Corporation shall provide compensation and benefits to the current and former employees of Company and its Subsidiaries (other than those current and former employees whose terms and conditions of employment are subject to a collective bargaining agreement) that are in the aggregate no less favorable than those provided to the current and former employees of Company and its Subsidiaries as of the Effective Time, subject to any changes made following the Effective Time in order to integrate Cobalt employees into the Company Plans.

(b) Pre-Existing Limitations; Service Credit. With respect to any Benefit Plans in which any employees of the Company or its Subsidiaries first become eligible to participate, on or after the Effective Time (the “New Company Plans”), Purchaser shall: (A) waive all pre-existing conditions, exclusions and waiting periods with respect to

participation and coverage requirements applicable to employees of the Company or its Subsidiaries under any health and welfare New Company Plans in which such employees may be eligible to participate after the Effective Time, and deductibles, coinsurance or maximum out-of-pocket payments made by such employees during the applicable plan year in which such employee first participates in the applicable New Company Plan occurs shall reduce the amount of deductibles, coinsurance and maximum out-of-pocket payments under the New Company Plans; provided that, for purposes of deductibles, coinsurance and out-of-pocket payments, such employee was enrolled under the Benefit Plans of Company immediately prior to the effective time of coverage in the New Company Plans, and (B) recognize service of present or former employees of Company or its Subsidiaries (or otherwise credited by Company or its Subsidiaries) accrued prior to the Effective Time for purposes of eligibility to participate and vesting credit (and levels of benefits) in any New Company Plan in which such employees may be eligible to participate after the Effective Time, to the extent such service would have been taken into account under the applicable Company Benefit Plans; provided, however, that in no event shall any credit be given to the extent it would result in the duplication of benefits for the same period of service.

(c) Company Plans. From and after the Effective Time, Purchaser shall and shall cause its affiliates (including its Subsidiaries and the Surviving Corporation) to honor all Company Plans in accordance with their terms as in effect immediately before the Effective Time, subject to any amendment or termination thereof that may be permitted by such terms.

(a) For six years after the Effective Time Purchaser shall, and shall cause the Surviving Corporation to, (i) indemnify and hold harmless the present and former directors, officers and employees of Company and its Subsidiaries (the “Indemnified Persons”) for any costs and expenses, judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such Indemnified

Person was an officer, director or employee of Company or its Subsidiaries in respect of acts or omissions occurring at or prior to the Effective Time (including those related to this Agreement and the transactions contemplated hereby), and shall advance expenses in respect thereof, in each case to the fullest extent permitted by applicable law and (ii) purchase as of the Effective Time a tail policy to the current policy of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by Company which tail policy shall be effective for a period from the Effective Time through and including the date six years after the Closing Date with respect to claims arising from facts or events that occurred on or before the Effective Time, and which tail policy shall contain substantially the same coverage and amounts as, and contain terms and conditions no less advantageous than, in the aggregate, the coverage currently provided by such current policy; provided, however, that in no event shall Purchaser be required to expend, for the entire tail policy, in excess of 900% of the annual premium currently paid by Company for its current policy of directors’ and officers’ liability insurance and fiduciary liability insurance as set forth on Section 5.7(a) of the Company Disclosure Schedule; and, provided, further that, if the premium of such insurance coverage exceeds such amount, Purchaser after consultation with Company shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(b) Any Indemnified Person wishing to claim indemnification under paragraph (a) of this Section 5.7, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Purchaser and the Surviving Corporation thereof, but the failure to so notify shall not relieve the Surviving Corporation of any liability it may have to such Indemnified Person if such failure does not materially prejudice the indemnifying party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Purchaser or the Surviving Corporation shall have the right to assume the defense thereof and neither Purchaser nor the Surviving Corporation shall be liable to such Indemnified Persons for any legal expenses of other counsel or any other expense subsequently incurred by such Indemnified Persons in connection with the defense thereof, except that if Purchaser or the Surviving Corporation elects not to assume such defense or counsel or the Indemnified Persons advise that there are issues which raise conflicts of interest between Purchaser or the Surviving Corporation and the Indemnified Persons, the Indemnified Persons may retain counsel satisfactory to them, and Purchaser shall and shall cause the Surviving Corporation to pay all reasonable fees and expenses of such counsel for the Indemnified Persons promptly as statements therefor are received; provided, however, the Surviving Corporation shall be obligated pursuant to this paragraph (c) to pay for only one firm of counsel for all Indemnified Persons in any jurisdiction, (ii) the Indemnified Persons will cooperate in the defense of any such matter and (iii) neither Purchaser nor the Surviving Corporation shall be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld); and provided, further, that neither Purchaser nor the Surviving Corporation shall have any obligation hereunder to any Indemnified Person if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Indemnified Person in the manner contemplated hereby is prohibited by applicable law.

(c) Notwithstanding anything herein to the contrary, if any claim, action, suit, proceeding or investigation (whether arising before, at or after the Effective Time) is made against any Indemnified Persons on or prior to the sixth anniversary of the Effective Time, the provisions of this Section 5.7 shall continue in effect until the final disposition of such claim, action, suit, proceeding or investigation.

(d) The covenants contained in this Section 5.7 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Persons and their respective heirs and legal representatives and shall not be deemed exclusive of any other rights to which an Indemnified Person is entitled, whether pursuant to law, contract or otherwise.

(e) In the event that Purchaser, 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 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 or assigns of Purchaser or the Surviving Corporation, as the case may be, shall succeed to the obligations set forth in this Section 5.7.

5.8. Notification of Certain Matters. Company shall use reasonable commercial efforts to give prompt notice to Purchaser, and Purchaser shall use reasonable commercial efforts to give prompt notice to Company, to the extent that either acquires actual knowledge of (i) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would be reasonably likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate and (ii) any failure of Purchaser, Merger Sub or Company, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 5.8 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

5.9. Public Announcements. Purchaser and Company shall develop a joint communications plan and each party shall (i) ensure that all press releases and other public statements and communications (including any communications that would require a filing under Rule 425, Rule 165 and Rule 166 of the Securities Act or Rule 14a-12 of the Exchange Act) with respect to this Agreement and the transactions contemplated hereby shall be consistent with such joint communications plan and (ii) unless otherwise required by applicable law or by obligations pursuant to any listing agreement with or rules of any securities exchange, consult with each other for a reasonable time before issuing any press release or otherwise making any public statement or communication (including any communication that would require a filing under Rule 425, Rule 165 and Rule 166 of the Securities Act or Rule 14a-12 of the Exchange Act), and mutually agree upon any such press release or any such public statement or communication, with respect to this Agreement or the transactions contemplated hereby. In addition to the foregoing, except to the extent disclosed in the Joint Proxy Statement in accordance with the provisions of Section 5.1, neither Purchaser nor Company shall issue any press release or otherwise make any public statement or disclosure concerning the other party or the other party’s business, financial condition or results of operations without the consent of the other party.

Promptly after execution and delivery of this Agreement, Company shall deliver to Purchaser a letter identifying all persons who, to the best of Company’s Knowledge, may be deemed as of the date hereof “affiliates” of Company for purposes of Rule 145 under the Securities Act, and such list shall be updated as necessary to reflect changes from the date thereof until the Effective Time. Company shall use its reasonable best efforts to cause each person identified on such list to deliver to Purchaser, on or before the date of mailing of the Joint Proxy Statement, a written agreement substantially in the form attached as Exhibit C hereto (an “Affiliate Agreement”).

Subject to applicable law, the Transition Team shall be responsible for developing, and monitoring the development of, and deliverables due under, an action plan for the combination of the businesses.

5.13. Tax-Free Reorganization Treatment. The parties hereto shall use their commercially reasonable efforts to cause the Merger to be treated as a reorganization within the meaning of Section 368(a) of the Code and shall not knowingly take or fail to take any action which action or failure to act would prevent (a) the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code or (b) the receipt of the opinions of tax counsel in such form and upon such matters as described in Section 6.2(c) and Section 6.3(c). Unless required by law, each of Purchaser, Merger Sub and Company shall not file any Tax Return or take any position inconsistent with the treatment of the Merger as a reorganization described in Section 368(a) of the Code. Prior to the Effective Time, the parties shall use their commercially reasonable efforts to obtain the opinions of tax counsel in such form and upon such matters as described in Section 6.2(c) and Section 6.3(c).

5.14. Takeover Statutes. Each of Company and Purchaser and their respective Boards of Directors shall, if any takeover statute or similar statute or regulation of any state becomes or may become applicable to this Agreement, the Merger, or any other transactions contemplated by this Agreement, grant such approvals and take such actions as are necessary to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such statute or regulation on this Agreement, the Merger and the other transactions contemplated by this Agreement.

5.15. Other Obligations. (i) Prior to the Closing, Company shall repurchase, by the Closing Date, for cash all commercial paper issued by Company or any of its Subsidiaries (whether outstanding as of the date hereof or issued hereafter with the consent of Purchaser in accordance with the terms of this Agreement) and shall repay all amounts outstanding under its credit facilities and (ii) from and after the date of this Agreement until the Closing, except with

Purchaser’s prior written consent, Company shall cause each of its Subsidiaries that is an insurance company or health maintenance organization to pay Ordinary Dividends on its outstanding capital stock at the earliest practicable time, subject to any restrictions imposed by or agreed to with governmental authorities, unless already paid. For purposes of this Agreement, “Ordinary Dividends” with respect to a Subsidiary means the payment of ordinary dividends by such Subsidiary in the ordinary course of business consistent with the past practice of such Subsidiary plus additional amounts reasonably necessary to allow Company to satisfy its obligations in Section 5.15(i) above; provided that such amounts are permitted to be distributed without the approval or consent of any applicable regulatory authorities.

5.16. Stockholder Litigation. Company shall consult with Purchaser and keep Purchaser informed about the defense of any stockholder litigation against Company and/or its officers or directors relating to the transactions contemplated by this Agreement.

Schaeffer) to resign from the Board of Directors of the Foundation, and any other charitable foundations established, controlled by or related to Company, in each case effective as of the Effective Time and will appoint the persons designated by Purchaser to fill the vacancies created by all such resignations effective as of the Effective Time.

Exhibit C

Form of WellPoint Health Networks Inc. Affiliate Letter

October 26, 2003

Anthem, Inc.

120 Monument Circle

Indianapolis, IN 46204

Ladies and Gentlemen:

I have been advised that, as of the date hereof, I may be deemed to be an “affiliate” of WellPoint Health Networks Inc., a Delaware corporation (the “Company”), as that term is defined for purposes of paragraphs (c) and (d) of Rule 145 of the Rules and Regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”).

Pursuant to the terms of the Agreement and Plan of Merger, dated as of October 26, 2003 (as it may be amended, supplemented or modified from time to time, the “Merger Agreement”), among Anthem, Inc., an Indiana corporation (“Purchaser”), Anthem Holding Corp., an Indiana corporation (“Merger Sub”), and the Company, the Company will be merged with and into Merger Sub (the “Merger”). Capitalized terms used herein but not defined shall have the respective meanings ascribed to such terms in the Merger Agreement.

In consideration of the agreements contained herein, Purchaser’s reliance on this letter in connection with the consummation of the Merger and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, I hereby represent, warrant and agree that I will not make any sale, transfer or other disposition of any shares of Purchaser Common Stock received by me pursuant to the Merger in violation of the Securities Act or the Rules and Regulations.

I have been advised that the issuance of the shares of Purchaser Common Stock pursuant to the Merger will have been registered with the Commission under the Securities Act on a Registration Statement on Form S-4. I have also been advised, however, that since I may be deemed to be an affiliate of the Company at the time the Merger is submitted for a vote of the stockholders of the Company, the Purchaser

Common Stock received by me in connection with the Merger may be disposed of by me only (i) pursuant to an effective registration under the Securities Act, (ii) in conformity with the provisions of Rule 145 promulgated by the Commission under the Securities Act (as such rule may hereafter be amended from time to time), (iii) in reliance upon an exemption from registration that is available under the Securities Act or (iv) after receipt of an opinion of counsel reasonably acceptable to Purchaser, or under a no-action or interpretative letter obtained from the Commission, stating that such sale, transfer or other disposition will not violate or is otherwise exempt from registration under the Securities Act.

I also understand that instructions will be given to Purchaser’s transfer agent with respect to the Purchaser Common Stock to be received by me pursuant to the Merger and that there will be placed on the certificates representing such shares of Purchaser Common Stock, or any substitutes therefor, a legend stating in substance as follows:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, APPLIES AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IN COMPLIANCE WITH THE REQUIREMENTS OF RULE 145 OR PURSUANT TO A REGISTRATION STATEMENT UNDER THAT ACT OR AN EXEMPTION FROM SUCH REGISTRATION.”

It is understood and agreed that the legend set forth above shall be removed at no cost to me upon surrender of certificates bearing such legend by delivery of substitute certificates without such legend if (i) one year shall have elapsed from the date that I received Purchaser Common Stock in the Merger and the provisions of Rule 145(d)(2) are then applicable to me, (ii) two years shall have elapsed from the date that I received Purchaser Common Stock in the Merger and the provisions of Rule 145(d)(3) are then applicable to me or (iii) I have delivered to Purchaser an opinion of counsel, in form and substance reasonably satisfactory to Purchaser, or a no-action or interpretative letter obtained from the Commission, to the effect that such legend is not required for purposes of the Securities Act.

I further understand and agree that Purchaser is under no obligation to register the sale, transfer or other disposition of Purchaser Common Stock by me or on my behalf under the Securities Act.

Neither execution of this letter nor any provisions set forth herein should be construed as an admission on my part that I am an “affiliate” of the Company as described in the first paragraph of this letter, or a waiver of any right I may have to object to any claim that I am such an affiliate on or after the date of this letter.

By Purchaser’s acceptance of this letter, Purchaser hereby agrees with me that, for a period of two years after the Effective Time, it shall use its reasonable efforts to (i) file, on a timely basis, all reports and data required to be filed with the Commission by it pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, and (ii) furnish to me upon request a written statement as to whether Purchaser has complied with such reporting requirements during the 12 months preceding any proposed sale of Purchaser Common Stock by me under Rule 145.

This letter agreement constitutes the complete understanding between Purchaser and me concerning the subject matter hereof. Any notice required to be sent to either party hereunder shall be sent by registered or certified mail, return receipt requested, using the addresses set forth herein or such other address as shall be furnished in writing by the parties. This letter agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of Indiana.

If you are in agreement with the foregoing, please so indicate by signing below and returning a copy of this letter to me, at which time this letter shall become a binding agreement between us.

		Very truly yours,
