Section 2.1                                      Conversion of Capital Stock.  At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holder of any shares of capital stock of the Company or of any membership interests of Merger Sub:

(a)                                  Conversion of Merger Sub Membership Interests.  Each membership interest of Merger Sub issued and outstanding immediately before the Effective Time shall be converted into and become one fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(c)                                  Conversion of Common Stock.

(i)                                     Each share of Common Stock issued and outstanding immediately before the Effective Time (other than Excluded Shares) shall be converted into the right to receive (A) from the Company, subject to the last sentence of Section 8.8, one (1) (the “Newco Exchange Ratio”) validly issued, fully paid and nonassessable share of Newco Common Stock (the “Split-Off Consideration”) and (B) from Parent, the Per Share Merger Consideration in cash, without interest (clauses (A) and (B), and any cash in lieu of fractional shares of Newco Common Stock to be issued or paid in accordance with Section 2.2(j), collectively, the “Closing Consideration”).

(d)                                 Conversion of Preferred Stock.

(i)                                     Each share of Series A Preferred Stock, par value $1.00 per share (the “Series A Preferred Stock”), issued and outstanding immediately before the Effective Time shall be converted into the right to receive an amount equal to the Closing Consideration for each share of Common Stock issuable upon conversion of such share of Series A Preferred Stock immediately before the Effective Time.

(ii)                                  All shares of Series A Preferred Stock that have been converted pursuant to Section 2.1(d)(i) shall be canceled automatically and shall cease to exist, and the holders of certificates which immediately before the Effective Time represented such shares (together with the certificates which represented shares of Common Stock, the “Certificates”) or shares represented by book-entry (together with the shares of Common Stock represented by book-entry, “Book-Entry Shares”) shall cease to have any rights with respect to those shares, other than the right to receive the Closing Consideration in accordance with Section 2.2, without interest.

4

split) or combination, exchange or readjustment of shares, or any stock dividend or stock distribution is declared with a record date during such period, the Closing Consideration shall be equitably adjusted to reflect such change.

Section 2.2                                      Surrender of Certificates and Book-Entry Shares.

(a)                                  Exchange Agent.  Not less than ten Business Days before the Effective Time, Parent shall (i) select a bank or trust company, satisfactory to the Company in its reasonable discretion, to act as the exchange agent in the Merger (the “Exchange Agent”) and (ii) enter into an exchange agent agreement with the Exchange Agent in form and substance reasonably satisfactory to the Company. Parent and Newco shall be responsible for all fees and expenses of the Exchange Agent as set forth in the Separation Agreement.

(b)                                 Exchange Fund.  At or before the Effective Time, for the benefit of the holders of Common Stock and Series A Preferred Stock (i) the Company shall provide to the Exchange Agent certificates representing the shares of Newco Common Stock issuable pursuant to Section 2.1(c) and Section 2.1(d) and (ii) Parent shall provide to the Exchange Agent cash in an amount sufficient for the payment of the aggregate Per Share Merger Consideration payable under Section 2.1(c) and Section 2.1(d).  Such shares of Newco Common Stock and funds provided to the Exchange Agent are collectively referred to as the “Exchange Fund.”

(c)                                  Exchange Procedures.

(i)                                     Letter of Transmittal.  As promptly as practicable but in no event later than two Business Days following the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a share of Common Stock or Series A Preferred Stock converted pursuant to Section 2.1(c)(i) or Section 2.1(d)(i), (A) a letter of transmittal in customary form, specifying that delivery shall be effected, and risk of loss and title to such holder’s shares shall pass, only upon proper delivery of Certificates to the Exchange Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the letter of transmittal and (B) instructions for surrendering such Certificates or Book-Entry Shares.

(ii)                                  Surrender of Shares.  Upon surrender of a Certificate or of a Book-Entry Share for cancellation to the Exchange Agent, together with a duly executed letter of transmittal and any other documents reasonably required by the Exchange Agent, the holder of that Certificate or Book-Entry Share shall be entitled to receive, and the Exchange Agent shall deliver in exchange therefor, the Closing Consideration deliverable in respect of the number of shares formerly evidenced by that Certificate or Book-Entry Share.  Any Certificates and Book-Entry Shares so surrendered shall be canceled immediately.  No interest shall accrue or be paid on the Closing Consideration deliverable upon surrender of Certificates or Book-Entry Shares.

(iii)                               Unregistered Transferees.  If any Closing Consideration is to be delivered to a Person other than the Person in whose name the

5

surrendered Certificate is registered, then the Closing Consideration may be delivered to such a transferee so long as (A) the surrendered Certificate is accompanied by all documents required by Parent to evidence and effect that transfer and (B) the Person requesting such delivery (1) pays any applicable transfer Taxes or (2) establishes to the reasonable satisfaction of Parent and the Exchange Agent that any such transfer Taxes have already been paid or are not applicable.

(iv)                              No Other Rights.  Until surrendered in accordance with this Section 2.2(c), each Certificate and each Book-Entry Share shall be deemed, from and after the Effective Time, to represent only the right to receive the Closing Consideration.  Any Closing Consideration delivered upon the surrender of any Certificate or Book-Entry Share shall be deemed to have been delivered in full satisfaction of all rights pertaining to such Certificate or Book-Entry Share and the shares of Common Stock or Series A Preferred Stock, as applicable, formerly represented by it.

(d)                                 Lost, Stolen or Destroyed Certificates.  If any Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by 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 Certificate, the Exchange Agent shall deliver, in exchange for such affidavit claiming such Certificate is lost, stolen or destroyed, the Closing Consideration to such Person in respect of the shares of Common Stock or Series A Preferred Stock, as applicable, represented by such Certificate.

(e)                                  No Further Transfers.  At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of the shares of Common Stock and Series A Preferred Stock that were outstanding immediately before the Effective Time.

(f)                                    Required Withholding.  Parent, Merger Sub, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from any consideration otherwise deliverable under this Agreement such amounts as may be required to be deducted or withheld therefrom under the Internal Revenue Code of 1986 (the “Code”), or any applicable state, local or foreign Tax Law. To the extent that any amounts are so deducted and withheld and paid to the appropriate Governmental Authorities, those amounts shall be treated as having been delivered to the Person in respect of whom such deduction or withholding was made for all purposes under this Agreement.

(g)                                 No Liability.  None of Parent, the Surviving Corporation, Newco or the Exchange Agent shall be liable to any holder of Certificates or Book-Entry Shares for any amount properly paid to a public official under any applicable abandoned property, escheat or similar Law.

(h)                                 Investment of Exchange Fund.  The Exchange Agent shall invest the cash portion of the Exchange Fund as directed by Parent; provided, that such

6

investment shall be in obligations of, or guaranteed by, the United States of America, in commercial paper obligations of issuers organized under the Law of a state of the United States of America, rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Ratings Service, respectively, or in certificates of deposit, bank repurchase agreements or bankers’ acceptances of commercial banks with capital exceeding $10 billion, or in mutual funds investing in such assets.  Any such investment shall be for the benefit, and at the risk, of Parent, and any interest or other income resulting from such investment shall be for the benefit of Parent; provided, that no such investment or losses thereon shall affect the Per Share Merger Consideration deliverable to former shareholders of the Company, and Parent shall promptly provide, or shall cause the Surviving Corporation to promptly provide, additional funds to the Exchange Agent for the benefit of the former shareholders of the Company in the amount of any such losses to the extent necessary to satisfy the obligations of Parent and the Surviving Corporation under this Article II.

(i)                                     Termination of Exchange Fund.

(i)                                     Any portion of the Exchange Fund that remains unclaimed by the holders of Certificates or Book-Entry Shares one year after the Effective Time shall be delivered by the Exchange Agent (A) in the case of the Fractional Shares Fund and shares of Newco Common Stock deposited in the Exchange Fund by the Company, to Newco and (B) in the case of the cash portion of the Exchange Fund (other than the Fractional Shares Fund), to Parent, in each case upon demand.

(ii)                                  Thereafter, any holder of Certificates or Book-Entry Shares who has not theretofore complied with this Article II shall look only to (A) Newco for, and Newco shall remain liable for, delivery of the Split-Off Consideration and (B) Parent for, and Parent shall remain liable for, delivery of the Per Share Merger Consideration, in each case pursuant to the terms of this Article II.

(j)                                     No Fractional Shares.

(i)                                     No fractional shares of Newco Common Stock shall be delivered upon the surrender for exchange of Certificates or Book-Entry Shares.

(ii)                                  In the event that the Company amends the Newco Exchange Ratio in accordance with Section 8.8 such that fractional shares of Newco Common Stock would be delivered to holders of Common Stock, as promptly as practicable following the Effective Time, Newco and Parent shall cause the Exchange Agent to aggregate all fractional share interests of Newco Common Stock, rounded down to the nearest whole share, and deliver such fractional share interests to its designated broker for sale on the open market at the then prevailing market prices, which sale or sales shall be completed as promptly as practicable following the Effective Time.  Newco and Parent shall cause the Exchange Agent to, upon receipt of the proceeds of such sale or sales from such designated broker, distribute the proceeds of such sale or sales to the holders of surrendered Certificates or Book-Entry Shares in lieu of fractional shares of Newco Common Stock. Until the proceeds of such sale or sales have been distributed to

7

the former holders of Certificates or Book-Entry Shares, the Exchange Agent shall hold such proceeds in an account for the benefit of such former holders (the “Fractional Shares Fund”).  The portion of the Fractional Shares Fund (net of any brokerage commissions retained by the Exchange Agent’s designated broker) to which each former holder of Certificates or Book-Entry Shares shall be entitled, if any, shall be determined by multiplying the amount of the aggregate proceeds comprising the Fractional Shares Fund (net of any brokerage commissions retained by the Exchange Agent’s designated broker) by a fraction, the numerator of which is the amount of the fractional share interests in Newco Common Stock to which such holder is entitled (after taking into account all shares of Common Stock held at the Effective Time by such holder (including shares of Common Stock issuable upon conversion of the Series A Preferred Stock)) and the denominator of which is the aggregate amount of fractional share interest in Newco Common Stock (after taking into account all shares of Common Stock held at the Effective Time by all holders (including shares of Common Stock issuable upon conversion of the Series A Preferred Stock)) to which all former holders of shares of Common Stock and Series A Preferred Stock are entitled.  Cash payments are being made to holders of Common Stock and Series A Preferred Stock in lieu of fractional shares of Newco Common Stock for the purpose of saving Newco the expense and inconvenience of issuing and transferring fractional shares.  Such cash payments do not represent separately bargained-for consideration.

Section 2.3                                      Part D Options; Part D Employee Restricted Shares; and Part D Employee Performance Shares.

(a)                                  The Company shall use reasonable best efforts so that, at the Effective Time, each Company Option that is outstanding immediately before the Effective Time and held by a Part D Employee or Former Part D Employee (as such term is defined in the Separation Agreement) (each, a “Part D Option”), whether or not vested and exercisable, by virtue of the Merger and without any action by Parent, Merger Sub, the Company or the holder of that Part D Option, shall be cancelled and converted at the Effective Time into the right to receive an amount from Parent in cash, without interest, that is equal to the excess, if any, of (i) the sum of (x) the Per Share Merger Consideration and (y) the value of the Split-Off Consideration (which shall be deemed for such purpose to be equal to the product of (A) the closing price of one share of Newco Common Stock on NASDAQ or the national securities exchange on which the shares of Newco Common Stock are traded on the first full day of trading after the Closing Date and (B) the Newco Exchange Ratio (the product of (A) and (B), the “Split-Off Consideration Value” and the sum of (x) and (y), the “Pre-Split-Off Common Stock Value”) over (ii) the per share exercise or purchase price of the applicable Part D Option (the “Exercise Price”), multiplied by the aggregate number of shares of Common Stock in respect of such Part D Option immediately before the Effective Time.  For the avoidance of doubt, if the Exercise Price of a Part D Option is equal to or exceeds the Pre-Split-Off Common Stock Value, such Part D Option shall be cancelled and terminated at the Effective Time without payment or consideration therefor and the holder of such Part D Option shall have no rights whatsoever with respect thereto.

8

(b)                                 Each Restricted Share that is outstanding immediately prior to the Effective Time and held by a Part D Employee or Former Part D Employee (each, a “Part D Employee Restricted Share”) shall, at the Effective Time, be cancelled and converted into the right to receive an amount in cash equal to (i) the Per Share Merger Consideration plus (ii) the Split-Off Consideration Value, on the same dates and subject to the same conditions on vesting as applied to the Part D Employee Restricted Share immediately prior the Effective Time, without any crediting of interest for the period from the Effective Time until vesting; provided, that if the Part D Employee’s employment with Parent and its Affiliates is terminated other than for “Cause” or by the Part D Employee for “Good Reason,” as such terms are defined on Section 5.7(d) of the Company Disclosure Letter, then such vesting shall be accelerated to the date of such termination (the “Converted Restricted Share Award”).

(c)                                  Each Earned Performance Share that is outstanding immediately prior to the Effective Time and held by a Part D Employee or Former Part D Employee (each, a “Part D Employee Performance Share”) shall, at the Effective Time, be cancelled and converted into the right to receive  an amount in cash equal to (i) the Per Share Merger Consideration plus (ii) the Split-Off Consideration Value, in each case of clauses (i) and (ii) on the first to occur of (x) the first anniversary of the date on which the Effective Time occurs and (y) the date the Part D Employee’s employment with Parent and its Affiliates is terminated other than for “Cause” or by the Part D Employee for “Good Reason,” as such terms are defined on Section 5.7(d) of the Company Disclosure Letter, without any crediting of interest for the period from the Effective Time until vesting (the “Converted Performance Share Award”).  The Company shall use reasonable best efforts so that, at the Effective Time, each Performance Share held by a Part D Employee or a Former Part D Employee that is not an Earned Performance Share is cancelled without consideration being due therefor.

(d)                                 As of and following the Effective Time, the Company shall retain all Liabilities in respect of the Part D Employee Restricted Shares, the Part D Employee Performance Shares and the Part D Options.

(e)                                  Parent and the Company shall, or shall cause their respective Affiliates to, take such action (including adopting, if appropriate, equity award plans) as is necessary or appropriate to effect the foregoing.

(f)                                    Except as described in clauses (a) through (e) above, all terms of the Part D Employee Performance Shares and the Part D Employee Restricted Shares as in existence on the Effective Time, including, in the case of the Part D Employee Restricted Shares, the vesting schedule and restrictions on transfer, shall continue to apply to the Converted Performance Share Awards and the Converted Restricted Share Awards, as applicable.

(g)                                 In addition to the payments made pursuant to this Section 2.3, Parent shall pay all accrued dividends and other distributions (including dividend equivalents) in respect of each Part D Employee Restricted Share and Part D Employee Performance Share with a record date prior to the Effective Time which have

9

been authorized by the Company and which remain unpaid at the Effective Time as set forth on Section 2.3(g) of the Company Disclosure Letter.  Such payments shall be made to the holders thereof simultaneously with the payments made in respect of the Converted Restricted Share Awards and Converted Performance Share Awards pursuant to Section 2.3(b) and Section 2.3(c), respectively.

(h)                                 Any payments made to Part D Employees pursuant to this Section 2.3 shall be reduced by any income or employment tax withholding required under (A) the Code, (B) any applicable state, local or foreign tax Law, and (C) any other applicable Laws.  To the extent that any amounts are so withheld and paid to the appropriate Governmental Authorities, those amounts shall be treated as having been paid to the holder of the applicable award, as applicable, for all purposes under this Agreement.

(i)                                     For the avoidance of doubt, the treatment of each Company Option, Restricted Share and Performance Share not held by a Part D Employee or a Former Part D Employee is set forth in Article VII of the Separation Agreement.

39

is provided to Parent substantially concurrently with the time it is provided to such Person except to the extent the provision of such information would constitute a violation of applicable Law) and (y) participate in discussions and negotiations regarding such Takeover Proposal.  The Company shall advise Parent orally and in writing of the receipt of any Takeover Proposal or any inquiry with respect to, or that could reasonably be expected to lead to, any Takeover Proposal (in each case within 24 hours of receipt thereof) and specify the terms and conditions thereof and the identity of the Person(s) making such Takeover Proposal.  The Company shall notify Parent (within 24 hours) orally and in writing of any material modifications to the financial or other material terms of such Takeover Proposal or inquiry.

(d)                                 Notwithstanding Section 5.4(c), the Company Board may, before obtaining the Requisite Company Vote, in response to a Superior Proposal received by the Company Board after the date of this Agreement, make a Company Adverse Recommendation Change, but only if:

(i)                                     the Company Board has concluded in good faith, following consultation with its outside legal counsel, that, in light of such Superior Proposal, its failure to make a Company Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable Law;

(ii)                                  such Superior Proposal did not result, directly or indirectly, from a breach by the Company of this Section 5.4;

(iii)                               the Company shall have first provided prior written notice to Parent of its intention to make a Company Adverse Recommendation Change, which notice shall include the most recent version of the proposed agreement under which the transaction contemplated by such Superior Proposal is proposed to be consummated and the identity of the Person(s) making such Superior Proposal; and

(iv)                              Parent does not make, within five Business Days after the receipt of such notice, a binding, written and complete (including any schedules or exhibits) proposal that the Company Board determines in good faith, after consultation with its financial advisor, causes the Takeover Proposal that constituted a Superior Proposal to no longer constitute a Superior Proposal (it being understood that any amendment to the financial terms or other material terms of such Superior Proposal shall require a new written notification pursuant to the foregoing clause (iii) and a new five-Business Day period under this clause (iv)).

40

(e)                                  Nothing contained in this Section 5.4 shall prohibit the Company from complying with Rules 14a-9, 14d-9, 14e-2 and Item 1012(a) of Regulation M-A promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its position thereunder, or making any required disclosure to the Company’s shareholders if, in the good faith judgment of the Company Board, after consultation with its outside legal counsel, the failure to do so would be inconsistent with its fiduciary duties under applicable Law or such disclosure is otherwise required under applicable Law; provided, in each case, that (x) any such action taken or disclosure made is consistent with this Section 5.4 and (y) unless the Company Board reaffirms the Company Board Recommendation in connection therewith within ten Business Days of the event that gave rise to such “stop, look and listen” statement, any such action or disclosure shall be deemed to constitute a breach of this Section 5.4(e); provided, further, that the foregoing proviso shall not apply following a Company Adverse Recommendation Change.

(f)                                    Notwithstanding Section 5.4(a), following the receipt by the Company of a bona fide, unsolicited written Takeover Proposal relating solely to the Non-Medicare Part D Business from any Person, which Takeover Proposal was made after the date of this Agreement and did not result from a breach of Section 5.4(a) or this Section 5.4(f), the Company may, in response to such Takeover Proposal, (x) furnish access and information with respect to the Non-Medicare Part D Business (but not any non-public information with respect to the Medicare Part D Business) to the Person who has made such Takeover Proposal pursuant to an Acceptable Confidentiality Agreement and (y) participate in discussions and negotiations regarding such Takeover Proposal; provided, that, prior to the Effective Time, the Company (i) shall not enter into any agreement, understanding or arrangement with respect to any such Takeover Proposal (other than an Acceptable Confidentiality Agreement) and (ii) shall not participate in discussions or negotiations regarding such Takeover Proposal if such participation would reasonably be expected to (A) adversely affect the Medicare Part D Business following the Effective Time or (B) materially delay or prevent the consummation of the transactions contemplated by this Agreement.  For purposes of this Section 5.4(f) only, the definition of the term “Takeover Proposal” shall be interpreted solely by reference to the Non-Medicare Part D Business.

(d)                                 Immediately prior to the Effective Time, the Company and Newco shall enter into a transition services agreement upon the terms set forth on Exhibit C (the “Transition Services Agreement”), which shall set forth the provision of transition support and other transition services after the Effective Time between the Newco Group and the Part D Group (as such terms are defined in the Separation Agreement).

(e)                                  As soon as practicable following the date of this Agreement, the Company and Parent shall work together in good faith to complete the Reinsurance Agreement, the PBM Agreement, the Novation Agreement and the Transition Services Agreement upon the terms contemplated by this Agreement.

healthcare insurance industry (the “Requisite Experience”) to assist in resolving any disputes between parties relating to the terms of such Split-Off Agreement (the “Split-Off Agreement Arbitrator”).  If the Company and Parent cannot agree upon a mutually acceptable arbitrator to be the Split-Off Agreement Arbitrator, then each of the Company and Parent shall select an arbitrator possessing the Requisite Experience, which two arbitrators shall mutually agree upon a third arbitrator possessing the Requisite Experience, who shall be appointed the Split-Off Agreement Arbitrator.  Within fifteen (15) days of such appointment, each of the Company and Parent shall submit to the Split-Off Arbitrator such Person’s proposed terms of such Split-Off Agreement, including such Person’s proposed final form of Split-Off Agreement. The Split-Off Agreement Arbitrator shall as promptly as practicable, and in no event more than forty-five (45) days follow its receipt of such submissions, review the terms of this Agreement and the terms of such Split-Off Agreement set forth in the applicable Exhibit and determine the final form of Split-Off Agreement in accordance with the terms thereof.  Such decision by the Split-Off Agreement Arbitrator shall be final and binding upon the Company and Parent.  The cost of such review and determination shall be borne equally by the Company and Parent.

(b)                                 Subject to applicable Law, the Company shall provide to Parent copies of (x) all material written notices received from any Governmental Authority by the Company or any of its Subsidiaries to the extent such notice is primarily related to the Medicare Part D Business and (y) all material written notices received from CMS by the Company or any of its Subsidiaries, in each case from and after the date of this Agreement until the Effective Time, provided that the foregoing shall not apply to the Company’s communications with CMS concerning the resolution of matters set forth in the November 2010 CMS Letter (as defined in Section 3.12 of the Company Disclosure Letter), except to the extent related, directly or indirectly, to the Medicare Part D Business.

Section 5.20                                Adjustment Certificates.

(a)                                  No later than March 14, 2011, the Company shall deliver to Parent a certificate executed by the Chief Financial Officer of the Company (the “Statutory Capital Adjustment Certificate”) setting forth the amount of each of (i) the Statutory Capital of Penn Life relating to the Medicare Part D Business as of December 31, 2010 (as adjusted, if at all, pursuant to Section 5.20(e), the “Statutory Capital 12/31 Amount”), (ii) the 2010 Annual Statement of Penn Life as filed with the Insurance Department of the State of Pennsylvania and (iii) the Authorized Control Level of Penn Life relating to the Medicare Part D Business as of December 31, 2010 (as adjusted, if at all, pursuant to Section 5.20(e), the “Authorized Control Level Amount”), in each case as calculated in accordance with the methodologies set forth in Section 5.20 of the Company Disclosure Letter.  No later than three Business Days prior to the Effective Time, the Company shall deliver to Parent a certificate executed by the Chief Financial Officer of the Company (the “Closing Date Indebtedness Certificate”) setting forth the amount of the Company Indebtedness (the “Closing Date Indebtedness Amount”).

(c)                                  Within fifteen (15) days after Parent’s receipt of the Statutory Capital Adjustment Certificate, Parent shall deliver to the Company a written statement either accepting the Statutory Capital Adjustment Certificate or specifying any objections thereto (including therein Parent’s calculations of such amounts and Parent’s grounds for such disagreement in reasonable detail) (a “Statutory Capital Objections Statement”).  The Statutory Capital Objections Statement shall specify those items or amounts as to which Parent disagrees, and Parent shall be deemed to have agreed with all other items and amounts contained in the calculations delivered by the Company pursuant to Section 5.20(a).

(d)                                 If Parent shall have delivered a Statutory Capital Objections Statement, the Company and Parent shall, during the fifteen (15) days following such delivery, negotiate in good faith to reach agreement on the disputed items

52

or amounts in order to determine, as may be required, the amounts set forth in the Statutory Capital Adjustment Certificate.  If the Company and Parent are unable to reach such agreement during such period, they shall promptly thereafter appoint an independent accountant of nationally recognized standing reasonably satisfactory to the Company and Parent (the “Statutory Capital Accounting Firm”) to promptly review this Agreement and the disputed items or amounts for the purpose of calculating the amounts set forth in the Statutory Capital Adjustment Certificate. In making such calculations, the Statutory Capital Accounting Firm shall consider only those items or amounts in the Statutory Capital Objections Statement.  The Statutory Capital Accounting Firm, acting as experts and not as arbitrators, shall determine in accordance with the methodologies set forth in Section 5.20 of the Company Disclosure Letter, the actual Statutory Capital 12/31 Amount and the Authorized Control Level Amount and shall deliver to the Company and Newco a written report setting forth such calculations. Such report shall be final and binding upon the Company and Parent.  The cost of such review and report shall be borne equally by the Company and Parent.

(e)           The parties agree that they will, and agree to cause their respective independent accountants and Subsidiaries to, cooperate and assist in the preparation of the calculations of the amounts set forth in the Statutory Capital Adjustment Certificate and in the conduct of the reviews referred to in this Section 5.20, including by making available to the extent necessary their respective books, records, work papers and personnel.

Section 5.22           2012 CMS Bid Process.

(a)           The Company shall, and shall cause the Part D Entities to, use commercially reasonable efforts consistent with past practice to participate in the Medicare Part D bid process for the 2012 plan year.  If the Closing has not occurred on or prior to May 1, 2011, the Company and Parent shall immediately thereafter jointly appoint an actuarial firm from among those firms set forth on Section 5.22 of the Company Disclosure Letter, which firm shall be reasonably acceptable to the Company and Parent (the “Actuarial Firm”), to review the bid submission(s) of the Company and/or the Part D Entities for the 2012 plan year (the “Bid Submission”) solely for the purpose of determining whether the Bid Submission constitutes a good faith bid consistent with the Company’s past practice in all material respects (a “Good Faith Bid”).  The Actuarial

53

Firm shall not be permitted to disclose to Parent or any of its Affiliates any information relating to the Bid Submission other than to state whether or not the Bid Submission constitutes a Good Faith Bid.

(b)           Within five Business Days from the date of appointment, the Company shall deliver the Bid Submission to the Actuarial Firm and the Actuarial Firm shall as soon as practicable, but in any event within seven days after receipt thereof, notify the Company of its determination as to whether the Bid Submission constitutes a Good Faith Bid. To the extent that the Actuarial Firm determines that the Bid Submission is not a Good Faith Bid, the Company shall work together with the Actuarial Firm in good faith to resolve any material issues identified by the Actuarial Firm in respect of the Bid Submission.

(c)           Nothing in this Section 5.22 shall be deemed to give Parent or any of its Affiliates any direct or indirect control of any bid submission of the Company or the Part D Entities prior to the Effective Time.

Section 5.23           Relationships with Certain Parties.  From the date hereof until the Effective Time, each of the Company and Parent shall, and shall cause their respective Subsidiaries to, consult and cooperate with each other concerning the communications of the Company and Parent with the Persons set forth on Section 5.23 of the Company Disclosure Letter (the “Section 5.23 Persons”) relating (a) to the Contracts between the Company and its Affiliates, on the one hand, and the Section 5.23 Persons, on the other hand, and (b) in any material respect to this Agreement, the Split-Off Agreements or the transactions contemplated hereby or thereby ((a) and (b) collectively, the “Section 5.23 Matters”).  In furtherance of the foregoing, neither the Company nor Parent shall participate in any meeting, or engage in any material substantive conversation, in each case relating to the Section 5.23 Matters, with any Section 5.23 Person without giving the other party prior notice of the meeting or conversation and the opportunity to attend or participate.  Each of Parent and the Company shall promptly inform the other party upon receipt of any communication from any Section 5.23 Person relating to the Section 5.23 Matters, and neither party shall enter into any understandings, undertakings or agreements (oral or written) with any Section 5.23 Person without the prior consent of the other party, in each case relating to the Section 5.23 Matters.  Prior to any written communication with a Section 5.23 Person relating to the Section 5.23 Matters, the Company or Parent, as the case may be, shall provide the other party with a reasonable opportunity to review and comment on such communication and shall include in such communication all comments reasonably proposed by such other party. Neither the Company nor Parent shall take any actions with respect to the Section 5.23 Matters that, to the Knowledge of the Company or Parent, as applicable, would reasonably be expected to prevent or to materially impede, delay or interfere with the Merger, the Split-Off or the other transactions contemplated by this Agreement or the Split-Off Agreements.  Promptly following the date of this Agreement, Parent and the Company shall meet jointly with the Section 5.23 Persons and Parent shall communicate the matters set forth on Section 5.23 of the Company Disclosure Letter to the Section 5.23 Persons.  For the avoidance of doubt, each of the Company and Parent acknowledges that the other

54

party maintains an ongoing business relationship with Section 5.23 Persons, and this Section 5.23 shall not prohibit the Company or Parent from engaging in communications or meetings with Section 5.23 Persons in the ordinary course of business consistent with past practice that are unrelated to the Section 5.23 Matters.  Neither Parent nor the Company shall be entitled to participate in, or receive notice of, any such excluded communications.

(a)           From time to time following the date of this Agreement (but no more than two (2) times prior to the Designation Date (as defined below)), the Company shall deliver to Parent at Parent’s request a schedule setting forth all bonds held by the Company and its Subsidiaries.  Such schedule shall set forth the material terms of each bond held by the Company and its Subsidiaries as of such date, including such bond’s outstanding principal amount, maturity date, original purchase price, investment credit rating and whether such bonds relate to the Medicare Part D Business or the Non-Medicare Part D Business.

55

(b)           Subject to the terms and conditions in this Section 5.25, Parent shall be entitled to designate one or more bonds held by the Company and its Subsidiaries (other than the Newco Bonds (as defined in the Separation Agreement)) with an investment credit rating of A2/A or lower to be sold by the Company prior to the Effective Time (such bond(s), the “Designated Part D Bonds”).  No less than 30 Business Days and no more than 60 Business Days prior to the Effective Time (the “Designation Date”), Parent shall identify by irrevocable written notice to the Company all Part D Designated Bonds.  Following receipt of such notice, the Company shall, prior the Effective Time, (i) sell (at the Company’s option) such Part D Designated Bonds to (A) a third party or (B) a member of the Newco Group (in the case of this clause (B) for a price equal to the fair market value of such Part D Designated Bond (valued as if such Part D Designated Bond were sold in an arm’s length transaction) and (ii) thereafter acquire, with the proceeds of such sale, bonds with an individual investment credit rating of A1/A+ or above (the “Designated Bond Exchange”).  Any gain or loss arising out of the Designated Bond Exchange (calculated by applying the value of the Part D Designated Bonds on a basis consistent with the Company’s historical valuation methods) shall be taken into account for purposes of determining Newco Cash in accordance with the terms of the Separation Agreement.

Section 5.26           Parent Standstill.  From the date of this Agreement until the Closing, Parent shall not, and shall not permit any person acting on behalf of Parent to, directly or indirectly, acquire (i) any Securities of the Company or (ii) any derivative contracts or derivative securities that give Parent or any Person acting on behalf of Parent the economic or voting equivalent of ownership of Securities of the Company.

(c)           If, at any time prior to the Effective Time, the Company shall determine that Merger Sub being a limited liability company instead of a corporation adversely affects in any material respect or materially delays the parties’ ability to effect the Merger then, at the Company’s request, upon no fewer than five (5) Business Days notice (which notice shall be given no later than five (5) Business Days before the Closing Date), Parent shall cause Merger Sub to convert to a corporation as promptly as practicable and the parties shall amend this Agreement to reflect such conversion.
