CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Dated:

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of January 10, 2006 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $800,000,000.

The Company will have the right to redeem the Securities at any time, at its option, on at least 30 days’ but no more than 60 days’ prior written notice mailed to the registered holders of the Securities to be redeemed. Upon redemption of the Securities, the Company will pay a redemption price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments (as defined below) of the notes to be redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, plus accrued and unpaid interest thereon to the Redemption Date.

“Treasury Rate” means, for any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity, computed as the second Business Day immediately preceding that redemption date, of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes to be redeemed.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, on the third Business Day preceding such redemption date, as contained in the daily statistical release, or any successor release, published by the Federal Reserve Bank of New York and designated “Composite 3:30 p.m. Quotations for U.S. Government Securities” or (2) if the release, or any successor release, is not published or does not contain these prices on that business day, (a) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations, or (b) if the trustee obtains fewer than four Reference Treasury Dealer Quotations, the average of all of these quotations.

“Independent Investment Banker” means the Reference Treasury Dealer appointed by the Company.

“Reference Treasury Dealer” means each of Banc of America Securities LLC, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Goldman, Sachs & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. Incorporated and their respective successors, or if at any time any of the above is not a primary U.S. Government securities dealer, one other nationally recognized investment banking firm that is a primary U.S. Government securities dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Remaining Scheduled Payments” means, with respect to each note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such note, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

If less than all the Securities are to be redeemed, the Securities to be redeemed shall be selected by the trustee by such method as the trustee deems fair and appropriate. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for redemption.

If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities in full, the Company will make an offer to each holder (the “Change of Control Offer”) to repurchase any and all (equal to $2,000 or an integral multiple of $1,000) of such holder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities repurchased plus accrued and unpaid interest, if any, thereon, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Company will be required to mail a notice to holders of Securities describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Securities on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the Securities and described in such notice. The Company must comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the Securities, the Company will be required to comply with the applicable securities laws and regulations and will not be deemed to

have breached its obligations under the Change of Control repurchase provisions of the Securities by virtue of such conflicts.

On the Change of Control Payment Date, the Company will be required, to the extent lawful, to accept for payment all Securities or portions of Securities properly tendered pursuant to the Change of Control Offer; deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly tendered; and deliver or cause to be delivered to the Trustee the Securities properly accepted, together with an officer’s certificate stating the principal amount of Securities or portions of Securities being purchased.

For purposes of the foregoing discussion of the applicable Change of Control provisions, the following definitions are applicable:

“Below Investment Grade Rating Event” means the Securities are rated below an Investment Grade Rating by each of the Rating Agencies (as defined below) on any date from the date of the public notice of an arrangement that could reasonably be expected to result in a Change of Control until the end of the 60-day period following public notice of the occurrence of the Change of Control (which 60-day period shall be extended so long as the rating of the Securities is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided, however, that a rating event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular change of control (and thus will not be deemed a rating event for purposes of the definition of change of control triggering event) if the rating agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the trustee in writing at its request or the request of the Company that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable change of control (whether or not the applicable change of control has occurred at the time of the rating event).

“Change of Control” means the occurrence of any of the following: (1) direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of WellPoint and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to WellPoint or one of its subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of WellPoint’s voting stock; or (3) the first day on which a majority of the members of WellPoint’s Board of Directors are not Continuing Directors; provided, however, that a transaction will not be deemed to involve a Change of Control if the Company becomes a wholly owned subsidiary of a holding company and the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of the voting stock of the Company immediately prior to that transaction. For purposes of this definition, “voting stock” means capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election

of directors (or persons performing similar functions) of WellPoint, even if the right to vote has been suspended by the happening of such a contingency.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Continuing Directors” means, as of any date of determination, any member of the Board of Directors of WellPoint who (1) was a member of the Board of Directors of WellPoint on the date of the issuance of the notes; or (2) was nominated for election or elected to the Board of Directors of WellPoint with the approval of a majority of the Continuing Directors who were members of such Board of Directors of WellPoint at the time of such nomination or election (either by specific vote or by approval of WellPoint’s proxy statement in which such member was named as a nominee for election as a director, without objection to such nomination).

“Fitch” means Fitch Ratings, Inc.

“Investment Grade Rating” means a rating by Moody’s equal to or higher than Baa3 (or the equivalent under a successor rating category of Moody’s), a rating by S&P equal to or higher than BBB- (or the equivalent under any successor rating category of S&P) or a rating by Fitch equal to or higher than BBB- (or the equivalent under any successor rating category of Fitch).

“Moody’s” means Moody’s Investors Service, Inc.

“Rating Agencies” means (1) Moody’s, S&P and Fitch; and (2) if any or all of Moody’s, S&P or Fitch ceases to rate the notes or fails to make the notes publicly available for reasons outside the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Company (as certified by a resolution of the Company’s Board of Directors) as a replacement agency for any of Moody’s S&P or Fitch, or all of them, as the case may be.

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also

contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity or security reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
