     THIS AGREEMENT dated as of [            ] between AMERIGROUP CORPORATION, a Delaware corporation (the “Company”), and [            ], a [bank] [trust company] duly incorporated and existing under the laws of [            ], as Warrant Agent (the “Warrant Agent”),

     Bracketed language here and throughout this Agreement should be inserted as follows:

     1. If Warrants are immediately detachable from the Offered Securities; and

     2. If Warrants are detachable from the Offered Securities only after the Detachable Date.

W I T N E S S E T H :

     [WHEREAS, the Company has entered into an Indenture dated as of [Date] (the “Senior Indenture”) between the Company and [           ], as Trustee (the “Senior Indenture Trustee”), and an Indenture dated as of [Date] (the “Subordinated Indenture”) between the Company and [           ], as Trustee (the “Subordinated Indenture Trustee”) (together the “Trustees” or “Trustee” and “Indentures” or “Indenture”), providing for the issuance from time to time of its unsecured debt securities to be issued in one or more series as provided in the Indenture; and]

     WHEREAS, the Company proposes to sell [title of such securities being offered] (the “Offered Securities”) with one or more warrants (the “Warrants”) representing the right to purchase [title of such securities purchasable through exercise of Warrants] (the “Warrant Securities”), the Warrants to be evidenced by warrant certificates issued pursuant to this Agreement (the “Warrant Certificates”); and

     WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company in connection with the issuance, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the terms and conditions on which they may be issued, transferred, exchanged, exercised and replaced;

     NOW, THEREFORE, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree as follows:

1

ARTICLE 1
ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT
CERTIFICATES

     SECTION 1.01. Issuance of Warrants.

     The Warrants shall be evidenced by one or more Warrant Certificates. Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein, to purchase [___shares of the Warrant Securities] [___aggregate principal amount of Warrant Securities] and shall be initially issued in connection with the issuance of the Offered Securities [1: and shall be separately transferable immediately thereafter] [2: but shall not be separately transferable until on and after      , (the “Detachable Date”)]. The Warrants shall be initially issued [in units] with the Offered Securities, and each Warrant [included in such a unit] shall evidence the right, subject to the provisions contained herein and in the Warrant Certificates, to purchase [___shares of the Warrant Securities] [___aggregate principal amount of Warrant Securities] [included in such a unit].

     SECTION 1.02. Execution and Delivery of Warrant Certificates.

     Each Warrant, whenever issued, shall be evidenced by a Warrant Certificate in registered form substantially in the form set forth in Exhibit A hereto, shall be dated and may have such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by its chairman or vice chairman of the Board of Directors, the chief financial officer, the president, any vice president, any assistant vice president, the treasurer or any assistant treasurer of the Company, which may but need not be attested by its secretary or one of its assistant secretaries. Such signatures may be manual or facsimile signatures of such authorized officers and may be imprinted or otherwise reproduced on the Warrant Certificates.

     No Warrant Certificate shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been countersigned by the Warrant Agent by manual signature. Such signature by the Warrant Agent upon any Warrant Certificate executed by the Company shall be conclusive evidence, and the only evidence, that the Warrant Certificate so countersigned has been duly issued hereunder.

     In case any officer of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent as provided herein, such Warrant Certificates may be countersigned and

2

delivered notwithstanding that the person who signed such Warrant Certificates ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution of this Agreement any such person was not such officer.

     The term “Holder,” when used with respect to any Warrant Certificate shall mean any person in whose name at the time such Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose [2: or, prior to the Detachable Date, any person in whose name at the time the Offered Security to which such Warrant Certificate is attached is registered upon the register of the Offered Securities. Prior to the Detachable Date, the Company will, or will cause the registrar of the Offered Securities to, make available at all times to the Warrant Agent such information as to holders of the Offered Securities with Warrants as may be necessary to keep the Warrant Agent’s records up to date.]

     SECTION 1.03. Issuance of Warrant Certificates.

     Warrant Certificates evidencing the right to purchase [___shares of the Warrant Securities] [an aggregate principal amount not exceeding ___aggregate principal amount of Warrant Securities] (except as provided in Sections 2.03, 3.02 and 4.01) may be executed by the Company and delivered to the Warrant Agent upon the execution of this Warrant Agreement or from time to time thereafter. The Warrant Agent shall, upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign Warrant Certificates evidencing [ ] Warrants representing the right to purchase up to [___shares of the Warrant Securities] [___aggregate principal amount of Warrant Securities] and shall deliver such Warrant Certificates to or upon the order of the Company. Subsequent to such original issuance of the Warrant Certificates, the Warrant Agent shall countersign a Warrant Certificate only if the Warrant Certificate is issued in exchange or substitution for one or more previously countersigned Warrant Certificates or in connection with their transfer as hereinafter provided or as provided in the antepenultimate paragraph of Section 2.03.

     Pending the preparation of definitive Warrant Certificates evidencing Warrants, the Company may execute and the Warrant Agent shall countersign and deliver temporary Warrant Certificates evidencing such Warrants (printed, lithographed, typewritten or otherwise produced, in each case in form satisfactory to the Warrant Agent). Such temporary Warrant Certificates shall be issuable substantially in the form of the definitive Warrant Certificates but with such omissions, insertions and variations as may be appropriate for temporary Warrant Certificates, all as may be determined by the Company with the concurrence of the Warrant Agent. Such temporary Warrant Certificates may contain such reference to any provisions of this Warrant Agreement as may be appropriate. Every such temporary Warrant Certificate shall be executed by the Company and shall be countersigned by the Warrant Agent upon the same conditions and in substantially the same manner, and with like effect, as the definitive Warrant Certificates. Without unreasonable delay, the Company shall execute and shall furnish definitive Warrant Certificates and thereupon such temporary Warrant Certificates may

3

be surrendered in exchange therefor without charge pursuant to and subject to the provisions of Section 4.01, and the Warrant Agent shall countersign and deliver in exchange for such temporary Warrant Certificates definitive Warrant Certificates of authorized denominations evidencing a like aggregate number of Warrants evidenced by such temporary Warrant Certificates. Until so exchanged, such temporary Warrant Certificates shall be entitled to the same benefits under this Warrant Agreement as definitive Warrant Certificates.

ARTICLE 2

     SECTION 2.01. Warrant Price.

     On [            ], the exercise price of each Warrant will be [            ]. During the period from [            ], through and including [            ], the exercise price of each Warrant will be [           ] [plus [accrued amortization of the original issue discount] [accrued interest] from ___.] [In each case, the original issue discount will be amortized at a [ ]% annual rate, computed on an annual basis using the “interest” method and using a 360-day year consisting of twelve 30-day months]. Such exercise price of Warrant Securities is referred to in this Agreement as the “Warrant Price.” [The original issue discount for each principal amount of Warrant Securities is         ].

     SECTION 2.02. Duration of Warrants.

     Subject to Section 4.03(b), each Warrant may be exercised [in whole but not in part] [in whole or in part] [at any time, as specified herein, on or after [the date thereof] [___] and at or before [time, location] on [            ] (each day during such period may hereinafter be referred to as an “Exercise Date”)] [on [list of specific dates] (each, an “Exercise Date”)], or such later date as the Company may designate by notice to the Warrant Agent and the Holders of Warrant Certificates [in registered form and to the beneficial owners of the Global Warrant Certificate] (the “Expiration Date”). Each Warrant not exercised at or before [time, location] on the Expiration Date shall become void, and all rights of the Holder [and any beneficial owners] of the Warrant Certificate evidencing such Warrant under this Agreement shall cease.

     SECTION 2.03. Exercise of Warrants.

     [With respect to Warrants evidenced by Warrant Certificates in registered form, during] [During] the period specified in Section 2.02, any whole number of Warrants may be exercised by providing certain information as set forth on the reverse side of the Warrant Certificates evidencing such Warrants and by paying in full [in lawful money of the United States of America] [in applicable currency] [in cash] [by certified check or official bank check or by bank wire transfer, in each case,] [by bank wire transfer] [in immediately available funds,] the Warrant Price for each Warrant exercised [(plus accrued interest, if any, on the Warrant Securities to be issued upon exercise of such Warrant from and including the Interest Payment Date (as defined in the Indenture), if any, in respect of such Warrant Securities immediately preceding the Exercise Date to

and including the Exercise Date (unless the Exercise Date is after the Regular Record Date (as defined in the Indenture), if any, for such Interest Payment Date, but on or before the immediately succeeding Interest Payment Date for such Warrant Securities, in which event no such accrued interest shall be payable))] to the Warrant Agent at its corporate trust office at [address] [or at      ], provided that such exercise is subject to receipt within five business days of such [payment] [wire transfer] by the Warrant Agent of the Warrant Certificate evidencing each Warrant exercised with the form of election to purchase Warrant Securities set forth on the reverse side of the Warrant Certificate properly completed and duly executed. [Cashless Exercise Option].

     The date on which payment in full of the Warrant Price (plus any such accrued interest) is received by the Warrant Agent shall, subject to receipt of the Warrant Certificate as aforesaid, be deemed to be the date on which the Warrant is exercised. The Warrant Agent shall deposit all funds received by it in payment for the exercise of Warrants in an account of the Company maintained with it (or in such other account as may be designated by the Company) and shall advise the Company, by telephone or by facsimile transmission or other form of electronic communication available to both parties, at the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited to its account. The Warrant Agent shall promptly confirm such advice to the Company in writing.

     If a day on which Warrants may be exercised in the city in which such Warrants are to be exercised shall be a Saturday or Sunday or a day on which banking institutions in such city are authorized or required to be closed, then, notwithstanding any other provision of this Agreement or the Warrant Certificate evidencing such Warrants, but subject to the limitation that no Warrant may be exercised after the Expiration Date, the Warrants shall be exercisable on the next succeeding day which in such city is not a Saturday or Sunday or a day on which banking institutions in such city are authorized or required to be closed.

     The Warrant Agent shall, from time to time, as promptly as practicable, advise the Company [and the Trustee] in writing of (i) the number of Warrants exercised, (ii) the instructions of each Holder of the Warrant Certificates evidencing such Warrants with respect to delivery of the Warrant Securities to be issued upon such exercise, (iii) delivery of any Warrant Certificates evidencing the balance, if any, of the Warrants remaining after such exercise, and (iv) such other information as the Company or the Trustee shall reasonably require.

     As soon as practicable after the exercise of any Warrant, but subject to receipt by the Warrant Agent of the Warrant Certificate evidencing such Warrant as provided in this Section, the Company shall issue[, pursuant to the Indenture, in authorized denominations to or upon the order of the Holder of the Warrant Certificate evidencing each Warrant,] the Warrant Securities to which such Holder is entitled, in fully registered form, registered in such name or names as may be directed by such Holder. If fewer than all of the Warrants evidenced by such Warrant Certificate are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign and

5

deliver, a new Warrant Certificate evidencing the number of such Warrants remaining unexercised.

     The Company shall not be required to pay any stamp or other tax or other governmental charge required to be paid in connection with any transfer involved in the issuance of the Warrant Securities, and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Security until such tax or other charge shall have been paid or it has been established to the Company’s satisfaction that no such tax or other charge is due.

ARTICLE 3
OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT

     SECTION 3.01. No Rights as Warrant Securityholder Conferred by Warrants or Warrant Certificates.

     No Warrant Certificate or Warrant evidenced thereby shall entitle the Holder or any beneficial owner thereof to any of the rights of a holder or beneficial owner of Warrant Securities, including, without limitation, [the right to receive the payment of principal of (premium, if any) or interest, if any, on Warrant Securities or to enforce any of the covenants in the Indenture] [the right to receive dividend payments on the Warrant Securities or any voting rights].

     SECTION 3.02. Lost, Mutilated, Stolen or Destroyed Warrant Certificates.

     Upon receipt by the Warrant Agent of evidence reasonably satisfactory to it and the Company of the ownership of and the loss, mutilation, theft or destruction of any Warrant Certificate and of such security or indemnity as may be required by the Company and the Warrant Agent to hold each of them and any agent of them harmless and, in the case of mutilation of a Warrant Certificate, upon surrender thereof to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute, and an authorized officer of the Warrant Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, mutilated, stolen or destroyed Warrant Certificate, a new Warrant Certificate of the same tenor and evidencing a like number of Warrants. Upon the issuance of any new Warrant Certificate under this Section, the Company may require the payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant to this Section in lieu of any lost, mutilated, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. The provisions of this Section are exclusive and shall preclude (to the extent

6

lawful) all other rights and remedies with respect to the replacement of lost, mutilated, stolen or destroyed Warrant Certificates.

     SECTION 3.03. Enforcement of Rights.

     Notwithstanding any of the provisions of this Agreement, any Holder of a Warrant Certificate, without the consent of the Warrant Agent, the Trustee, the holder of any Offered Securities or the Holder of any other Warrant Certificate, may, in its own behalf and for its own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, its right to exercise its Warrants in the manner provided in its Warrant Certificate and in this Agreement.

     SECTION 3.04. Merger, Consolidation, Conveyance or Transfer.

     (a) If at any time there shall be a merger or consolidation of the Company or a conveyance or transfer of its property and assets substantially as an entirety [as permitted under the Indenture], then in any such event the successor or assuming corporation referred to therein shall succeed to and be substituted for the Company, with the same effect[, subject to the Indenture,] as if it had been named herein and in the Warrant Certificates as the Company; the Company shall thereupon, except in the case of a transfer by way of lease, be relieved of any further obligation hereunder and under the Warrants and the Warrant Certificates, and the Company as the predecessor corporation, except in the case of a transfer by way of lease, may thereupon or at any time thereafter be dissolved, wound up or liquidated. Such successor or assuming corporation may thereupon cause to be signed, and may issue either in its own name or in the name of the Company, Warrant Certificates evidencing any or all of the Warrants issuable hereunder which theretofore shall not have been signed by the Company, and may execute and deliver Warrant Securities in its own name [, pursuant to the Indenture], in fulfillment of its obligations to deliver Warrant Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same legal rank and benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Warrants had been issued at the date of the execution hereof. In any case of any such merger, consolidation, conveyance or transfer, such changes in phraseology and form (but not in substance) may be made in the Warrant Certificates representing the Warrants thereafter to be issued as may be appropriate.

     (b) The Warrant Agent may receive a written opinion of legal counsel (who shall be acceptable to the Warrant Agent) as conclusive evidence that any such merger, consolidation, conveyance or transfer complies with the provisions of this Section and the Indentures.

     SECTION 4.03. Cancellation of Warrant Certificates.

     [(a)] Any Warrant Certificate surrendered for exchange or registration of transfer or exercise of the Warrants evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent, and all Warrant Certificates surrendered or so delivered to the Warrant Agent shall be promptly cancelled by the Warrant Agent and shall not be reissued and, except as expressly permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor or in lieu thereof. The Warrant Agent shall cause all cancelled Warrant Certificates to be destroyed and shall deliver a certificate of such destruction to the Company.

     [(b) If the Company notifies the Trustee of its election to redeem [2: prior to the Detachable Date] [, as a whole but not in part,] [2: the Offered Securities [or] [and]] the Warrant Securities pursuant to the Indenture or the terms thereof, the Company may elect, and shall give notice to the Warrant Agent of its election, to cancel the unexercised Warrants, the Warrant Certificates and the rights evidenced thereby. Promptly after receipt of such notice by the Warrant Agent, the Company shall, or, at the Company’s request, the Warrant Agent shall in the name of and at the expense of the Company, give notice of such cancellation to the Holders of the Warrant Certificates, such notice to be so given not less than 30 nor more than 60 days prior to the date fixed for the redemption of [2: the Offered Securities [or] [and]] the Warrant Securities pursuant to the Indenture or the terms thereof. The unexercised Warrants, the Warrant Certificates and the rights evidenced thereby shall be cancelled and become void on the 15th day prior to such date fixed for redemption.]

     (a) Compensation and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation to be agreed upon with the Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket expenses (including reasonable attorneys’ fees) incurred by the Warrant Agent without negligence, bad faith or willful misconduct or breach of this Agreement on its part in connection with the services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct on the part of the Warrant Agent, arising out of or in connection with its acting as Warrant Agent hereunder, as well as the reasonable costs and expenses of defending against any claim of such liability.

     (b) Agent for the Company. In acting under this Agreement and in connection with the Warrants and the Warrant Certificates, the Warrant Agent is acting solely as agent of the Company and does not assume any obligation or relationship of agency or trust for or with any of the Holders of Warrant Certificates or beneficial owners of Warrants.

     (e) Certain Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner of, or acquire any interest in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted by applicable law, it or they may engage or be interested in any financial or other transaction with the Company and may act on, or as depositary, trustee or agent for, any committee or body of holders of Warrant Securities or other obligations of the

10

Company as freely as if it were not the Warrant Agent hereunder. [Nothing in this Warrant Agreement shall be deemed to prevent the Warrant Agent from acting as Trustee under the Indenture.]

     (f) No Liability for Interest. The Warrant Agent shall have no liability for interest on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates.

     (g) No Liability for Invalidity.

     (b) The Warrant Agent may at any time resign as such by giving written notice of its resignation to the Company, specifying the desired date on which its resignation shall become effective; provided, however, that such date shall be not less than 90 days after the date on which such notice is given unless the Company agrees to accept shorter notice. Upon receiving such notice of resignation, the Company shall promptly appoint a

11

successor Warrant Agent (which shall be a bank or trust company in good standing, authorized under the laws of the jurisdiction of its organization to exercise corporate trust powers) by written instrument in duplicate signed on behalf of the Company, one copy of which shall be delivered to the resigning Warrant Agent and one copy to the successor Warrant Agent. The Company may, at any time and for any reason, remove the Warrant Agent and appoint a successor Warrant Agent (qualified as aforesaid) by written instrument in duplicate signed on behalf of the Company and specifying such removal and the date when it is intended to become effective, one copy of which shall be delivered to the Warrant Agent being removed and one copy to the successor Warrant Agent. Any resignation or removal of the Warrant Agent and any appointment of a successor Warrant Agent shall become effective upon acceptance of appointment by the successor Warrant Agent as provided in this subsection (b). In the event a successor Warrant Agent has not been appointed and accepted its duties within 90 days of the Warrant Agent’s notice of resignation, the Warrant Agent may apply to any court of competent jurisdiction for the designation of a successor Warrant Agent. Upon its resignation or removal, the Warrant Agent shall be entitled to the payment by the Company of the compensation and to the reimbursement of all reasonable out-of-pocket expenses (including reasonable attorneys’ fees) incurred by it hereunder as agreed to in Section 5.02(a).

     (c) The Company shall remove the Warrant Agent and appoint a successor Warrant Agent if the Warrant Agent (i) shall become incapable of acting, (ii) shall be adjudged bankrupt or insolvent, (iii) shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, (iv) shall consent to, or shall have had entered against it a court order for, any such relief or to the appointment of or taking possession by any such official in any involuntary case or other proceedings commenced against it, (v) shall make a general assignment for the benefit of creditors or (vi) shall fail generally to pay its debts as they become due. Upon the appointment as aforesaid of a successor Warrant Agent and acceptance by it of such appointment, the predecessor Warrant Agent shall, if not previously disqualified by operation of law, cease to be Warrant Agent hereunder.

     (d) Any successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor and the Company an instrument accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance, shall become vested with all the authority, rights, powers, immunities, duties and obligations of such predecessor with like effect as if originally named as Warrant Agent hereunder, and such predecessor shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be entitled to receive, all monies, securities and other property on deposit with or held by such predecessor as Warrant Agent hereunder.

     (e) Any corporation into which the Warrant Agent hereunder may be merged or

12

converted or any corporation with which the Warrant Agent may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or substantially all the assets and business of the Warrant Agent, provided that it shall be qualified as aforesaid, shall be the successor Warrant Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto.
