          SECTION 2.01. Purchase and Sale of the Shares. Upon the terms and subject to the conditions of this Agreement, at the Closing, the Seller shall sell, assign, transfer, convey and deliver, or cause to be sold, assigned, transferred, conveyed and delivered, to the Purchaser, the Shares, and the Purchaser shall purchase the Shares.

          SECTION 2.02. Purchase Price. (a) Subject to the adjustments set forth in Sections 2.07, 2.08 and 2.09, the purchase price for the Shares shall be $280 million less (i) the amount of the Estimated Tax Liability (as provided in Section 2.02(b)), (ii) the Net Closing Date Indebtedness, (iii) the Total Option Consideration (as defined in Section 2.06(b)(iii)), and (iv) the Accrued Bonuses (as defined in Section 6.01) (the “Purchase Price”). The Purchaser shall deduct from the Purchase Price (including any amounts payable under Sections 2.08, 2.09 or 8.07), and the Seller shall cause Medifax to deduct from the Total Option Consideration, any amounts required to be withheld or deducted under the Code or other applicable Tax Law; provided, however, that the Purchaser shall give the Seller written notice of any such withholding with respect to the Purchase Price (including any amounts payable under Sections 2.08, 2.09 or Section 8.07), within five (5) Business Days of the Closing or other date of such payment, as applicable, so as to give the Seller time to obtain, file or provide any exemption certificate or other document to reduce or eliminate any such withholding; and provided further, however, that in the event that the Seller does not give the Purchaser written notice of its intention to so obtain, file or provide any such certificate or document within two (2) days of the Purchaser giving the Seller notice pursuant to this Section 2.02(a), the Purchaser shall be entitled to withhold such amounts and remit them to the appropriate taxing authority.

All material assets, properties and risks of the Company and each Acquired Subsidiary are covered by valid and currently effective insurance policies or binders of insurance (including general liability insurance, property insurance, workers’ compensation insurance, directors and officers insurance, errors and omissions insurance and business interruption insurance) issued in favor of the Company or an Acquired Subsidiary, as the case may be, in such types and amounts and covering such risks as are consistent with customary practices and standards of companies engaged in businesses and operations similar to those of the Company or such Acquired Subsidiary, as the case may be. Except as set forth in Section 3.23 of the Disclosure Schedule, with respect to each insurance policy and insurance binder of the Company and the Acquired Subsidiaries, all payment amounts due to the insurer by the Company or an Acquired Subsidiary on or prior to the date hereof have been timely paid, no amounts are past due thereunder and the premium and adjustments that will be due from the date hereof until the expiration date of such policies and binders will not exceed $200,000 in the aggregate.

56

operation are in the public domain.

57

approval or authorization as promptly thereafter as practicable.

Except as set forth in Section 5.05(c), such notification shall not affect or otherwise limit the Purchaser’s right to enforce the terms of this Agreement and all Schedules hereto as they existed on the date hereof, without taking into account such notification.

          (b) The Seller shall have the right from time to time prior to the Closing to supplement or amend the Disclosure Schedule; provided, however, that the Seller must provide the Purchaser with a written notice of any such supplement or amendment (the “Schedule Update Notice”) that describes, in reasonable detail, the matter giving rise to the supplement or amendment. Except as set forth in Section 5.05(c), such supplements and amendments shall not affect or otherwise limit the Purchaser’s right to enforce, whether prior to or after the consummation of the transactions contemplated by this Agreement and the Ancillary Agreements, the terms of this Agreement and all Schedules hereto as they existed on the date hereof, without taking into account such supplements or amendments.

In the event that such Schedule Update Notice states that the matter giving rise to the supplement or amendment of Section 3.27 or Section 3.16(a)(i) (to the extent such supplement or amendment relates to a customer Contract), 3.16(a)(xvi) (to the extent such supplement or amendment relates to a customer Contract), Section 3.16(a)(xx) or Section 3.16(a)(xxi) of the Disclosure Schedule would be reasonably likely to cause a Closing condition set forth in Section 7.02 to be unsatisfied, the Purchaser shall have the right, within ten (10) Business Days of receipt of such Schedule Update Notice to terminate this Agreement pursuant to Section 9.01(e) hereof. In the event (i) the Schedule Update Notice states that the matter giving rise to the supplement or amendment of Section 3.27 or Section 3.16(a)(i) (to the extent such supplement or amendment relates to a customer Contract), 3.16(a)(xvi) (to the extent such supplement or amendment relates to a customer Contract), Section 3.16(a)(xx) or Section 3.16(a)(xxi) of the Disclosure Schedule would be reasonably likely to cause a Closing condition set forth in Section 7.02 to be unsatisfied, and the Purchaser does not terminate this Agreement

pursuant to Section 9.01(e) within ten (10) Business Days of receipt of such Schedule Update Notice, then the information on such Schedule Update Notice shall update the Disclosure Schedule as if such information was included on the Disclosure Schedule as of the date hereof and the Purchaser shall have no further right to delay the Closing, terminate this Agreement or seek indemnification as a result of a representation or warranty of the Seller set forth in Section 3.16(a)(i) (to the extent such supplement or amendment relates to a customer Contract), 3.16(a)(xvi) (to the extent such supplement or amendment relates to a customer Contract), Section 3.16(a)(xx) or Section 3.16(a)(xxi) or 3.27 being untrue because of the facts set forth in such Schedule Update Notice. In the event (i) the Schedule Update Notice states that the matter giving rise to the supplement or amendment of Section 3.27 or Section 3.16(a)(i) (to the extent such supplement or amendment relates to a customer Contract), 3.16(a)(xvi) (to the extent such supplement or amendment relates to a customer Contract), Section 3.16(a)(xx) or Section 3.16(a)(xxi) of the Disclosure Schedule would not be reasonably likely to cause a Closing condition set forth in Section 7.02 to be unsatisfied and (ii) the parties subsequently consummate the transactions contemplated by this Agreement and the Ancillary Agreements, then such supplement or amendment shall not affect or otherwise limit any Purchaser Indemnified Parties’ (as defined in Section 8.02) right to enforce after the Closing the terms of this Agreement and all Schedules hereto as they existed on the date hereof, without taking into account such supplements or amendments.

          SECTION 5.06. No Solicitation or Negotiation. The Seller agrees that between the date of this Agreement and the earlier of (a) the Closing and (b) the termination of this Agreement, none of the Seller, the Company, the Subsidiaries or any of their respective Affiliates, officers, directors, representatives or agents will (i) solicit, initiate, consider, encourage or accept any other proposals or offers from any Person (A) relating to any acquisition or purchase of all or any portion of the capital stock of the Company or any Acquired Subsidiary or substantially all of the assets of the Company or any Acquired Subsidiary (other than the Distributed Subsidiaries), (B) to enter into any merger, consolidation or other business combination involving or otherwise relating to the Company, any Acquired Subsidiary or the business of the Company or the Acquired Subsidiaries or (C) to enter into a recapitalization, reorganization or any other extraordinary business transaction involving or otherwise relating to the Company or any Acquired Subsidiary or (ii) participate in any discussions, conversations, negotiations and other communications regarding, or furnish to any other Person any information with respect to, or otherwise cooperate in any way, assist or participate in, facilitate or encourage any effort or attempt by any other Person to seek to do any of the foregoing. The Seller immediately shall cease and cause to be terminated all existing discussions, conversations, negotiations and other communications with any Persons conducted heretofore with respect to any of the foregoing. The Seller shall notify the Purchaser promptly if any such proposal or offer, or any inquiry or other contact with any Person with respect thereto, is made and shall, in any such notice to the Purchaser, indicate in reasonable detail the identity of the Person making such proposal, offer, inquiry or contact and the terms and conditions of such proposal, offer, inquiry or other contact. The Seller agrees not to, and to cause the Company and each Acquired Subsidiary not to, without the prior written consent of the Purchaser, release any Person from, or waive any provision of, any confidentiality or standstill agreement to which the Seller or any Subsidiary is a party.

59

          SECTION 5.07. Use of Intellectual Property. (a) The Seller acknowledges that from and after the Closing, the name “medifax”, “MediFax-EDI”, “Medi”, “MedWare” and all similar or related names, marks and logos (all of such names, marks and logos being the “Company Marks”) shall be owned by the Company or an Acquired Subsidiary, that neither the Seller nor any of its Affiliates shall have any rights in the Company Marks and that neither the Seller nor any of its Affiliates will contest the ownership or validity of any rights of the Purchaser, the Company or any Acquired Subsidiary in or to the Company Marks.

          (b) From and after the Closing, neither the Seller nor any of its Affiliates shall use any of the Company Intellectual Property, or any of the Licensed Intellectual Property or any of the IT Systems.

          SECTION 5.08. Non-Competition. (a) For a period of two (2) years after the Closing (the “Non-Competition Restricted Period”), neither the Seller nor its Affiliates as of the date of this Agreement shall engage, directly or indirectly, in any business anywhere in the world that develops, implements or provides products or services of the kind developed, implemented or provided by the Company or any Acquired Subsidiary as of the Closing or, without the prior written consent of the Purchaser, directly or indirectly, own an interest in, manage, operate, join, control, lend money or render financial or other assistance to or participate in or be connected with, as an officer, employee, partner, stockholder, consultant or otherwise, any Person that is in the business of providing claims, eligibility, ERA, referral/authorization or other healthcare transaction services to healthcare providers or payors that are provided by the Company or any Acquired Subsidiary as of the Closing or practice management systems to physician practices; provided, however, that for the purposes of this Section 5.08, an ownership interest (other than a Controlling Interest (as defined below)) in any competitor shall not be deemed to be in violation of this Section 5.08; and provided further, however that, notwithstanding the foregoing, as this Section 5.08 applies to First Islamic Investment Bank, E.C. (“First Islamic”) or Crescent Capital Investments, Inc. (“Crescent”) pursuant to the Crescent/First Islamic Letter Agreement (as defined below), the ownership interest in Smart Document Solutions, Inc. held by Affiliates of First Islamic and Crescent shall not be deemed to be in violation of this Section 5.08. For purposes of this Section 5.08, “Controlling Interest” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of voting securities (or other ownership interest), by contract or otherwise.

          (b) As a separate and independent covenant, the Seller agrees with the Purchaser that, for a period of five (5) years following the Closing (the “Non-Solicitation/Non-Hire Restricted Period), neither Seller nor any of its Affiliates as of the date of this Agreement will in any way, directly or indirectly, for the purpose of conducting or engaging in any business that develops, implements or provides products or services of the kind developed, implemented or provided by the Company or any Acquired Subsidiary as of the Closing, call upon, solicit, advise or otherwise do, or attempt to do, business with any customers of the Company or any Acquired Subsidiary with whom the Company or any Acquired Subsidiary had any dealings during the period of time in which the Company was an Affiliate of the Seller or take away or interfere or attempt to interfere with any custom, trade, business or patronage of the Company or any Acquired Subsidiary, or interfere with or attempt to interfere with any officers, employees, representatives or agents of the Company or any Acquired Subsidiary, or hire, induce or attempt

60

to induce any of them to leave the employ of the Company or any Acquired Subsidiary or violate the terms of their contracts, or any employment arrangements, with the Company or any Acquired Subsidiary.

          (c) The Non-Competition Restricted Period and the Non-Solicitation/Non-Hire Restricted Period, as applicable, shall be extended by the length of any period during which the Seller or any of its Affiliates is in breach of the terms of this Section 5.08.

          (d) The Seller acknowledges that its covenants set forth in this Section 5.08 are an essential element of this Agreement and that, but for the agreement of the Seller on behalf of itself and its Affiliates to comply with these covenants, the Purchaser would not have entered into this Agreement. The Seller has independently consulted with its counsel and after such consultation agrees that the covenants set forth in this Section 5.08 are reasonable and proper.

          SECTION 5.09. Release of Obligations and Encumbrances. (a) The Seller covenants and agrees, on or prior to the Closing, to execute and deliver to the Company, for the benefit of the Company and each Acquired Subsidiary, a general release and discharge, in form and substance satisfactory to the Purchaser, releasing and discharging the Company and each Acquired Subsidiary from any and all obligations to indemnify the Seller or otherwise hold it harmless pursuant to any agreement or other arrangement entered into prior to the Closing.

          SECTION 5.10. Intercompany Arrangements. Prior to the Closing, the Seller shall cause any contract or arrangement that is disclosed (or should have been disclosed) in Section 3.11(b) or 3.11(c) of the Disclosure Schedule, other than those contracts or arrangements set forth in Section 5.10 of the Disclosure Schedule, to be terminated or otherwise amended to exclude the Company and any Acquired Subsidiary as a party thereto.

          SECTION 5.11. Distributions of Certain Subsidiaries of Medifax. (a) On the Closing Date but prior to the Closing, the Company shall cause Medifax to distribute its entire equity interest in each Distributed Subsidiary to the Company, and immediately thereafter and prior to the Closing, the Seller shall cause the Company to distribute its entire equity interest in each Distributed Subsidiary to the Seller (such distributions, collectively, the “Initial Distribution”). In consideration for the Initial Distribution, the Seller shall deliver to the Company stock certificates evidencing the Redeemed Shares, which shall be cancelled by the Company upon consummation of the Initial Distribution. The parties agree that the Initial Distribution shall be treated for federal income Tax purposes as consideration in exchange for the Redeemed Shares pursuant to Revenue Ruling 79-273, 1979-2 C.B. 125. Notwithstanding anything to the contrary contained in this Agreement, upon a sale or other disposition of Apollo, Working Rx, or ABOL, Inc. by the Seller (or its Affiliate) within two (2) years of the date of the Initial Distribution, the Seller shall provide written notice to the Purchaser within fifteen (15) days of the execution of an agreement to consummate a Distributed Subsidiary Sale but in no

61

event less than thirty (30) days prior to the closing of such Distributed Subsidiary Sale setting forth the material terms of such transaction, including, without limitation, the purchase price received by the Seller (or its Affiliate) in connection with such transaction.

          (b) In connection with the Initial Distribution, the Seller shall (i) terminate, or cause to be terminated, on terms reasonably satisfactory to the Purchaser, all Contracts to which the Seller or any of its Affiliates, on the one hand, and the Company, any Acquired Subsidiary or any of their respective Affiliates (other than the Distributed Subsidiaries), on the other hand are parties that relate to the Distributed Subsidiaries; (ii) release, or caused to be released, on terms reasonably satisfactory to the Purchaser, the Company, the Acquired Subsidiaries and their respective Affiliates from all obligations arising under such Contracts described in clause (i); and (iii) settle all intercompany arrangements between Seller or any of its Affiliates, on the one hand, and the Company, any Acquired Subsidiary or any of their respective Affiliates (other than the Distributed Subsidiaries), on the other hand.

The Seller shall cause the Company’s Accountants to prepare a true and complete audited consolidated balance sheet of the Company and the Acquired Subsidiaries for each of the two fiscal years ended as of December 31, 2001 and December 31, 2002, and the related audited consolidated statements of income, stockholders’ equity and cash flows of the Company and the Acquired Subsidiaries (together with all related notes and schedules thereto, and the reports thereon of the Company’s Accountants, referred to herein as the “Audited Medical Services Financial Statements”).

          SECTION 5.13. Separation Agreement. The Seller shall, for so long as the Seller or any of its Affiliates controls a Distributed Subsidiary, cause such Distributed Subsidiary to perform its obligations arising under the Separation Agreement and the Purchaser shall, for so long as the Purchaser or any of its Affiliates controls the Company or any Acquired Subsidiary, cause the Company and such Acquired Subsidiaries to perform their respective obligations arising under the Separation Agreement.

          SECTION 5.14. No Other Representations and Warranties. The Purchaser acknowledges that, except as set forth in Article III of this Agreement, none of the Seller, its Affiliates or any of their respective officers, directors, employees or representatives make or have made any other representation or warranty, express or implied, at law or in equity, in respect of the Company, the Subsidiaries, the Shares or any of the assets of the Company or the Subsidiaries.

          SECTION 5.15. Further Action. Each of the parties hereto shall use all reasonable best efforts to take, or cause to be taken, all appropriate action, do or cause to be done all things necessary, proper or advisable under applicable Law, and to execute and deliver such documents and other papers, as may be required to carry out the provisions of this Agreement and consummate and make effective the transactions contemplated by this Agreement.

ARTICLE VI

EMPLOYEE MATTERS

          SECTION 6.01. Benefits. As soon as practicable after the Closing (but not earlier than January 1, 2004, in the case of any Purchaser welfare plan), employees of the Company or any Acquired Subsidiary as of the Closing shall be offered participation in employee benefit plans, programs, policies and arrangements of the Purchaser and its subsidiaries (the “Purchaser Companies”) that provide benefits that are substantially comparable in the aggregate to those provided under the applicable employee benefit plans (as defined in Section 3(3) of ERISA (excluding plans exempt under Section 201(2) of ERISA)) of the Purchaser Companies generally available to similarly situated employees of the Purchaser Companies; provided, however, that nothing contained in this Section 6.01 shall (a) obligate or commit the Purchaser Companies to continue any particular employee benefit plan, program or arrangement after the Closing or to maintain in effect any particular plan or any level or type of benefits or (b) prohibit the Purchaser Companies from making any changes to any of their employee benefit plans, programs or arrangements; provided further, however, that the Purchaser shall continue the welfare plans of the Company or any Acquired Subsidiary until the welfare plans of the Purchaser are extended to such employees. The Purchaser shall, or shall cause the Company to, honor all contractual employee benefit obligations to current and former employees of the Company or any Acquired Subsidiary under the Plans in accordance with their terms. The Purchaser shall cause the Company to pay at the Closing to the employees of the Company and the Acquired Subsidiaries set forth on Section 6.01(a) of the Disclosure Schedule (the “Designated Employees”), the bonuses set forth for such employees reflected on such Section 6.01(a) of the Disclosure Schedule, and the Purchaser shall cause the remaining amount of the accrued bonuses set forth in Section 6.01(b) of the Disclosure Schedule (the aggregate amounts set forth in Sections 6.01(a) and (b) of the Disclosure Schedule, collectively referred to herein as, the “Accrued Bonuses”), to be paid to the other employees of the Company and the Acquired Subsidiaries not later than January 31, 2004, with the identity of, and amount to be paid to, each other such employee to be in accordance with the recommendation of David F. Bacon, Jr. in reasonable consultation with the Purchaser; provided that such employee remains employed by the Company or an Acquired Subsidiary as of the payment date; and provided further that in no event shall the Purchaser be obligated to pay or to cause the Company to pay bonuses to employees of the Company and the Acquired Subsidiaries for the year ended December 31, 2003 in an amount greater than the amount set forth in Section 6.01 of the Disclosure Schedule. The Purchaser shall cause each employee benefit plan of the Purchaser Companies in which employees of the Company or any Acquired Subsidiary are eligible to participate to take into account only for purposes of eligibility and vesting thereunder (but not for purposes of benefit accrual, including, without limitation, any contributions under any performance incentive plans of the Purchaser Companies) the service of such employees with the Company or any Acquired Subsidiary as if such service were with a member of the Purchaser Companies, to the same extent that such service was credited under a comparable plan of the Company or any Acquired Subsidiary. The Purchaser will, or will cause the Company and the Acquired Subsidiaries to, credit each employee of the Company and the Acquired Subsidiaries as of the Closing with such number of unused vacation days and other paid time off accrued by each employee with the Company and the Acquired Subsidiaries prior to the Closing Date in accordance with the Company’s personnel policies applicable to such employees on the date hereof, copies of which

63

have been made available to the Purchaser; provided that the Purchaser may, in its sole discretion, require that such vacation and other paid time off be taken by the employee prior to December 31, 2005. The Purchaser shall be responsible, or shall cause Medifax or an Acquired Subsidiary to be responsible, for providing COBRA health care continuation coverage with respect to all employees or former employees (and their eligible dependents) of Medifax or an Acquired Subsidiary who are “M&A qualified beneficiaries” (as that term is defined in the regulations promulgated under COBRA) in connection with this Agreement who as of the Closing are currently receiving or are eligible to elect to receive COBRA continuation coverage through, or participate in, an employee health benefit plan subject to COBRA sponsored by Medifax or an Acquired Subsidiary.

          SECTION 6.02. Additional Employment Agreements. As promptly as practicable after the date hereof, the Seller and the Purchaser shall work together in good faith to cause each of the employees set forth in Section 6.02 of the Disclosure Schedule to enter into an employment agreement (collectively, the “Additional Employment Agreements”) reasonably satisfactory to the Purchaser.

          SECTION 6.03. 401(k) Plan. Prior to the Closing, the Seller shall, and shall cause each Distributed Subsidiary, on the one hand, and Medifax, on the other hand, to cooperate to take all actions necessary to (x) terminate the status of Medifax as the “sponsoring employer” under the Medifax 401(k) Savings/Retirement Plan (the “401(k) Plan”), (y) terminate the status of the Acquired Subsidiaries as “adopting employers” under the 401(k) Plan and (z) cause the 401(k) Plan and related trust to be transferred to, and assumed by (including all Liabilities relating thereto), a Distributed Subsidiary designated by the Seller, in accordance with the terms and conditions set forth in the 401(k) Plan and applicable Law. The Seller shall, and shall cause each Distributed Subsidiary, on the one hand, and Medifax, on the other hand, to, also cooperate to take all actions necessary, including, if applicable, amending the 401(k) Plan, to provide that all employees of Medifax or an Acquired Subsidiary who participate in the 401(k) Plan as of the Closing Date (i) receive a matching contribution at a rate of not less than fifty percent (50%) of the first six percent (6%) of pay contributed by each participant pursuant to the 401(k) Plan for the 2003 fiscal year, which matching contributions shall be made as of the Closing Date and (ii) are 100% vested in their account balances under the 401(k) Plan as the Closing Date. By no later than January 1, 2004, the Purchaser shall offer the employees of the Company and the Acquired Subsidiaries the opportunity to participate in the WebMD 401(k) Savings Plan or other plan qualified under Section 401(a) of the Code of the Purchaser Companies on a basis that is substantially comparable to that provided under the WebMD 401(k) Savings Plan to similarly situated employees of the Purchaser Companies.

          SECTION 6.04. Certain Medifax Employee Plans.

          Prior to the Closing the Seller shall, and shall cause each Distributed Subsidiary, on one hand, and Medifax, on the other hand, to cooperate to take all actions necessary to provide that all current or former employees or directors of the Distributed Subsidiaries who participate in any plan, program or arrangement maintained by Medifax or an Acquired Subsidiary, including, without limitation, the Medifax Flexible Benefit Plan (No. 507) and the Medifax Insurance Benefits Plan (No. 501) (collectively, the “Shared Medifax Employee Plans”) cease participation in such Shared Medifax Employee Plans as of the Closing Date and the Seller

64

shall cause a Distributed Subsidiary designated by the Seller to assume, and release Medifax and the Acquired Subsidiaries from, all Liabilities, relating to such current or former employees or directors of the Distributed Subsidiaries arising under or in connection with such Shared Medifax Employee Plans.

          SECTION 6.05. Assumption of Employment Agreements. Effective as of the Closing Date, the Seller shall cause a Distributed Subsidiary designated by the Seller, on terms reasonably satisfactory to the Purchaser, to assume, and release Medifax and the Acquired Subsidiaries from, all Liabilities arising under, or relating to, the employment agreements set forth in Section 6.05 of the Disclosure Schedule.

          SECTION 6.06. Liabilities and Obligations. Effective as of the Closing Date, the Seller shall cause a Distributed Subsidiary designated by the Seller, on terms reasonably satisfactory to the Purchaser, to assume, and release Medifax and the Acquired Subsidiaries from, all Liabilities relating to the employment or engagement (or termination thereof) and compensation and employee or other benefits of any current or former employees or directors of any Distributed Subsidiary, including, without limitation, any Liabilities arising under, or relating to, the Medifax Shared Benefits Plans, the Medifax Change of Control Severance Policy – Senior Management Level and the Medifax Change of Control Severance Policy – Manager Level.

          SECTION 6.07. 280G Letter Agreements. At least five (5) Business Days prior to the Closing Date, the Seller shall cause each of the employees set forth in Section 6.08 of the Disclosure Schedule to enter into a letter agreement (collectively, the “280G Letter Agreements”), substantially in the form attached hereto as Exhibit 6.07.

For purposes of this Agreement, the “Claims Period” shall be the period after the Closing Date during which a claim for indemnification may be asserted under this Agreement by any Indemnified Party (as defined below). The Claims Period under this Agreement with respect to all Losses (as defined below) of an Indemnified Party (excluding claims for Taxes, claims related to Sections 3.20(a), (b), (c), (d), (f) or (h) and

69

claims related to clause (iii) of the second sentence of Section 3.04(b), for which the Claims Period shall commence on the Closing and shall terminate on the second (2^nd) anniversary of the Closing) shall commence on the Closing and shall terminate on the first (1^st) anniversary of the Closing. The representations and warranties of the Seller and the Purchaser contained in this Agreement and the Ancillary Agreements shall survive the Closing until the first (1^st) anniversary of the Closing (excluding the representations and warranties of the Seller contained in Sections 3.20(a), (b), (c), (d), (f) or (h), Section 3.22 or set forth in clause (iii) of the second sentence of Section 3.04(b) and any covenants of the Seller relating to Taxes, which shall survive the Closing until the second (2^nd) anniversary of the Closing). Notwithstanding the foregoing, if prior to the close of business on the last day of the Claims Period, an Indemnifying Party (as defined below) shall have been properly notified of a claim for indemnity hereunder and such claim shall not have been finally resolved or disposed of at such date, such claim shall continue to survive, and shall remain a basis for indemnity hereunder until such claim is finally resolved or disposed of in accordance with the terms herein. Neither the period of survival nor the liability of the Seller with respect to the Seller’s representations and warranties shall be reduced by any investigation made at any time by or on behalf of the Purchaser.

          SECTION 8.02. Indemnification by the Seller. The Purchaser, the Company and the Acquired Subsidiaries (each a “Purchaser Indemnified Party”) shall be indemnified and held harmless by the Seller for and against any and all Liabilities, losses, Taxes, diminution in value, damages, claims, costs and expenses, interest, awards, judgments and penalties (including attorneys’ and consultants’ fees and expenses) actually suffered or incurred by them (including any Action brought or otherwise initiated by any of them) (hereinafter a “Loss”), arising out of or resulting from:

70

To the extent that the Seller’s undertakings set forth in this Section 8.02 may be unenforceable, the Seller shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Purchaser Indemnified Parties.

          SECTION 8.03. Indemnification by the Purchaser. The Seller and its Affiliates, officers, directors, employees, agents, successors and assigns (each a “Seller Indemnified Party”) shall be indemnified and held harmless by the Purchaser for and against any and all Losses, arising out of or resulting from:

To the extent that the Purchaser’s undertakings set forth in this Section 8.03 may be unenforceable, the Purchaser shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Seller Indemnified Parties.

          SECTION 8.04. Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement, (a) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 8.02(a) or 8.03(a), unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds $1.75 million (the “Basket Amount”) in which case each Indemnified Party shall be entitled to indemnification for the entire amount of such Loss and (b) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 8.02 or 8.03, as the case may be, shall be an amount equal to the Escrow Amount. Notwithstanding anything herein to the contrary, the provisions of Section 8.04(a) shall not apply (i) with respect to indemnification of the Purchaser Indemnified Parties for any Excluded Taxes pursuant to 8.02 hereof or for any breach by the Seller of the representations and warranties set forth in Sections 3.22 or 3.25 or clause (iii) of the second sentence of Section 3.04(b) or (ii) with respect to indemnification of the Seller Indemnified Parties for any breach by the Purchaser of the representations and warranties set forth in Section 4.07. Subject to Section 8.10, any obligation of the Seller to indemnify and hold harmless any Purchaser Indemnified Party for and against any Losses hereunder shall be payable solely out of distributions of the Escrow Amount in accordance with the terms of the Escrow Agreement.

71

          SECTION 8.05. Notice of Loss; Third Party Claims. (a) If an Indemnified Party shall determine that there is any matter that has given or could give rise to a right of indemnification under this Agreement, that does not involve a Third Party Claim (as defined below), such an Indemnified Party shall give the Indemnifying Party written notice of such matter within sixty (60) days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. As promptly as possible after the Indemnified Party has given such notice, such Indemnified Party and the appropriate Indemnifying Party shall establish the merits and amount of such claim (by mutual agreement, litigation or otherwise) and, within five (5) Business Days of the final determination of the merits and amount of such claim, the Indemnifying Party shall pay, or cause to be paid, immediately available funds to the Indemnified Party in an amount equal to such claim as determined hereunder, if any.

          (b) If an Indemnified Party shall receive notice of any Action, audit, demand or assessment (each, a “Third Party Claim”) against it or which may give rise to a claim for Loss under this Article VIII, within thirty (30) days of the receipt of such notice, the Indemnified Party shall give the Indemnifying Party written notice of such Third Party Claim; provided, however, that the failure to provide such notice shall relieve the Indemnifying Party from its obligations under this Article VIII only if and to the extent that the Indemnifying Party is actually prejudiced as a result of such failure and shall not relieve the Indemnifying Party from any other obligation or Liability that it may have to any Indemnified Party otherwise than under this Article VIII.

72

73

          (d) The following procedures apply to the Third Party Claims for which a Seller Indemnified Party is entitled to indemnification pursuant to Section 8.01:

          SECTION 8.06. Tax Matters. (a) From and after the Closing, the Purchaser shall prepare and file or otherwise furnish to the appropriate taxing authority (or cause to be

74

prepared and filed or so furnished) in a timely manner all estimated and final Tax Returns relating to the Company and the Subsidiaries for any Pre-Closing Tax Period (other than any separate Tax Returns relating to the Distributed Subsidiaries that do not include the operations of the Company or any Acquired Subsidiary). Such Tax Returns shall be prepared in a manner consistent with (i) past practices employed with respect to the Company and the Subsidiaries (except to the extent that counsel for the Purchaser reasonably determines in writing that a Tax Return cannot be so prepared and filed without being subject to penalties) and (ii) except as otherwise provided by Section 8.07, the determination of the Final 2003 Tax Liability pursuant to Section 2.09 of this Agreement, unless a Distributed Subsidiary Sale occurs and the applicable Distributed Subsidiary Purchase Price is believed to be better evidence of the fair market value of the applicable Distributed Subsidiary on the date of the Initial Distribution than the applicable Distributed Subsidiary Valuation set forth on the Statement of Final Tax Liability, in which case the Distributed Subsidiary Purchase Price shall be used in calculating such gain. Notwithstanding anything to the contrary in this Section 8.06(a), in connection with its preparation and filing of Tax Returns for the Company and its Subsidiaries for a taxable period that includes the Initial Distribution, the Purchaser shall be permitted to use a value for the Initial Distribution in excess of the Distributed Subsidiary Valuation or, if applicable, the Distributed Subsidiary Purchase Price under Sections 2.09, 8.07 or 8.08 hereof if, in the reasonable judgment of the Purchaser, the use of such other value would be advisable; provided, however, that any Tax owing on such excess shall not constitute an Excluded Tax. The Purchaser shall provide the Seller and its authorized representatives with a draft of each such Tax Return at least thirty (30) days prior to the due date (including any applicable extensions) for filing thereof (unless the Seller has delivered a Subsequent Statement of Tax Liability pursuant to Section 8.07(a), in which case the Purchaser shall provide a draft of any applicable Tax Return ten (10) days prior to the due date (including any applicable extensions) for filing thereof), and the Seller shall have the right to review and approve (which approval shall not be unreasonably withheld) each such Tax Return within ten (10) days following its receipt thereof (unless the Seller has delivered a Subsequent Statement of Tax Liability pursuant to Section 8.07(a), in which case the Seller shall have the right to review and approve (which approval shall not be unreasonably withheld) any applicable Tax Return within five (5) days following its receipt . The failure of the Seller to propose any changes to any such Tax Return within such ten-day period or such five-day period, as applicable, shall be deemed to constitute the Seller’s approval thereof. The Purchaser and the Seller shall attempt in good faith mutually to resolve any disagreements regarding such Tax Returns prior to the due date (including any applicable extensions) for filing thereof; provided, however, that the failure to resolve all disagreements prior to such date shall not relieve the Purchaser of its obligation to file (or cause to be filed) any such Tax Return in accordance with this Section 8.06(a) and to pay any Taxes due in connection with such Tax Returns. In connection with the filing of Tax Returns pursuant to this Section 8.06(a), the Seller and the Purchaser shall jointly instruct the Escrow Agent to disburse, at least three (3) Business Days before the due date (including any applicable extensions) of the applicable Tax Return, an amount equal to the portion of such Taxes that are Excluded Taxes and that are not in dispute. To the extent that the Purchaser and the Seller do not resolve any disagreements regarding amounts shown as due and payable on such Tax Returns that constitute Excluded Taxes, such dispute shall be resolved in accordance with the provisions of the Escrow Agreement governing claims by a Purchaser Indemnified Party for indemnification for Losses under Section 8.02 of this Agreement (except for any disputes resolved pursuant to Section 8.07), and in the event such

75

dispute is resolved in favor of the Purchaser, a disbursement shall be made from the Escrow Account to the Purchaser equal to such resolved amount.

          (b) Any Conveyance Taxes payable solely in connection with the sale of the Shares shall be borne equally by the Seller and the Purchaser. The Seller, after review and consent by the Purchaser, shall file any applications and documents as shall permit any such Conveyance Taxes to be assessed and paid on or prior to the Closing Date in accordance with any available pre-sale filing procedure; provided that the Purchaser shall execute and deliver all instruments and certificates necessary to enable the Seller to comply with the foregoing. To the extent any such Conveyance Taxes are not paid prior to the Closing Date, the Purchaser and the Seller shall jointly instruct the Escrow Agent to disburse to the Purchaser from the Escrow Amount, within thirty (30) days after the Closing Date, an amount equal to the amount of any Conveyance Taxes payable by the Seller pursuant to this Section 8.06(b) which were not paid by the Company prior to the Effective Time. Notwithstanding anything to the contrary contained in this Agreement, the Seller shall be responsible for all Conveyance Taxes arising in connection with the Initial Distribution.

          (c) All payments payable under any Tax sharing agreement (or other similar arrangement) between the Seller (or any Affiliate thereof) and the Company (or any Subsidiary) shall be calculated on a basis consistent with past practice and shall be payable in full prior to the Closing Date. Any such agreement or arrangement between the Seller (or any Affiliate thereof) and the Company (or any Subsidiary) shall be terminated prior to the Closing Date.

          (d) The parties agree to treat all payments made by either of them to or for the benefit of the other (including any payments to the Company or any Subsidiary) under any indemnity provision of this Agreement and for any misrepresentations or breaches of warranties or covenants as adjustments to the Purchase Price for Tax purposes and that such treatment shall govern for purposes hereof except to the extent that the Laws of a particular jurisdiction provide otherwise, in which case such payments shall be made in an amount sufficient to indemnify the relevant party on an after-Tax basis.

          (e) The Seller and its Affiliates shall provide (and shall cause any parties currently assisting the Company and the Subsidiaries in connection with the preparation of any Tax Returns to provide) the Purchaser with such cooperation and information as the Purchaser reasonably may request in filing any Tax Return, amended Tax Return or claim for refund, determining a liability for Taxes or a right to a refund of Taxes or participating in or conducting any audit or other proceeding in respect of Taxes or making representations to or furnishing information to parties subsequently desiring to purchase the Company or any Acquired Subsidiary (or any assets of the Company or any Acquired Subsidiary) from the Purchaser. Such cooperation and information shall include providing copies of relevant Tax Returns or portions thereof, together with related work papers and documents relating to rulings or other determinations by taxing authorities.

          (f) In the case of any Tax refund or equivalent benefit actually realized through a reduction in any Tax Liability (including any interest with respect thereto) relating to the Company or any Subsidiary for any Pre-Closing Tax Period, or to the extent any claim for refund or other proceeding results in a refund or credit against Tax by a taxing authority to the

76

Purchaser, the Company or any Acquired Subsidiary of an amount taken into account in the calculation, if any, of the liability for Excluded Taxes on the Closing Statement of Adjusted Net Assets, the Purchaser shall deposit such refund or an amount equal to such credit into the Escrow Account within ten (10) Business Days of the Purchaser’s receipt of such refund or credit and such deposited amount shall thereafter be subject to the terms of the Escrow Agreement. After the second (2nd) anniversary of the Closing, any such Tax refund or credit received by the Purchaser, the Company or any Acquired Subsidiary shall be paid to the Seller within fifteen (15) Business Days after receipt or entitlement thereto. Notwithstanding the foregoing, any Tax refund or equivalent benefit through a reduction in Tax Liability (including any interest with respect thereto) for a Pre-Closing Tax Period (i) arising out of the carryback of a loss or credit incurred by the Company or any Acquired Subsidiary in a taxable period ending after the Closing Date or (ii) relating to a payment previously made to the Seller pursuant to Section 2.09 or Section 8.07 shall be the property of the Purchaser.

          SECTION 8.07. Seller Subsequent Statement of Tax Liability. (a) In the event of a Distributed Subsidiary Sale that was not taken into account in connection with the resolution of the Final Statement of Tax Liability, the Seller may, at least fifty-five (55) days prior to the extended due date for the filing of the Final Consolidated Tax Return (and, in any event, prior to the second (2^nd) anniversary of the Closing), prepare and deliver to the Purchaser a written statement (the “Subsequent Statement of Tax Liability”) asserting that the applicable Distributed Subsidiary Purchase Price is believed to be better evidence of the fair market value of the applicable Distributed Subsidiary on the date of the Initial Distribution than the applicable Distributed Subsidiary Valuation set forth on the Statement of Final Tax Liability and setting forth, in reasonable detail, the Seller’s determination of the aggregate Tax Liability of the Company and the Subsidiaries attributable to (i) the U.S. federal, state and local Income Tax Liability of the Company and the Subsidiaries for the taxable period (or the portion thereof) ending on the Closing Date (the “Subsequent 2003 Tax Liability”) and (ii) the amount of any Conveyance Taxes payable in connection with the Initial Distribution (such aggregate amount, the “Subsequent Tax Liability”).

          (b) Dispute Resolution. With respect to any Subsequent Statement of Tax Liability pursuant to Section 8.07, the parties shall have negotiation, dispute and access to information rights substantially similar to those contained in Section 2.09.

          (c) Adjustment of Purchase Price. Within three (3) Business Days of the completion of the finally determined Subsequent Statement of Tax Liability pursuant to this Section 8.07, if the Subsequent Tax Liability reflected on the Subsequent Statement of Tax Liability differs from the Final Tax Liability (as adjusted to reflect any previous adjustment pursuant to Section 8.07 or Section 8.08), then the Purchase Price shall be adjusted as follows:

77

          SECTION 8.08. Purchaser Subsequent Statement of Tax Liability. (a) In the event of a Distributed Subsidiary Sale that was not taken into account in connection with the resolution of the Final Statement of Tax Liability, the Purchaser may, at any time prior to the second (2nd) anniversary of the Closing, the Purchaser may prepare and deliver to the Seller a Subsequent Statement of Tax Liability setting forth, in reasonable detail, the Purchaser’s determination of the Subsequent Tax Liability.

          (b) Dispute Resolution. With respect to any Subsequent Statement of Tax Liability pursuant to Section 8.08, the parties will have negotiation, dispute and access to information rights substantially similar to those contained in Section 2.09.

          (c) Adjustment of Purchase Price. Within three (3) Business Days of the completion of the finally determined Subsequent Statement of Tax Liability pursuant to this Section 8.08, if the Subsequent Tax Liability reflected on the Subsequent Statement of Tax Liability exceeds the Final Tax Liability (as adjusted to reflect any previous adjustment pursuant to Section 8.07 or Section 8.08), then the Purchase Price shall be adjusted downward, and the Purchaser shall be entitled to a distribution equal to such amount from the Escrow Amount in accordance with the terms of the Escrow Agreement.

          SECTION 8.09. Adjustment of Escrow Amount. (a) In the event that any Distributed Subsidiary and the Company dispute the Statement of Tax Position (as defined in Section 7.03 of the Separation Agreement) delivered pursuant to Section 7.03(a) of the Separation Agreement and such dispute remains unresolved at the time the applicable Distributed Subsidiary Sale is consummated, the Seller agrees to deposit (or cause to be deposited) into the Escrow Account an amount equal to the Unresolved Tax Position Amount (as defined in Section 7.03 of the Separation Agreement). Within three (3) Business Days of the resolution of all such disputes regarding amounts reflected on the Statement of Tax Position (i) the Purchaser shall be entitled to a distribution from the Escrow Amount equal to the finally determined Adjusted Tax Position Amount (as defined in Section 7.03 of the Separation Agreement), if such amount is a positive number, and (ii) the Seller shall be entitled to a distribution equal to the Unresolved Tax Position Amount less the portion of the finally determined Adjusted Tax Position Amount paid to the Purchaser from the Escrow Account, if such difference is a positive number; provided, that with respect to such distribution to the Seller, the Seller shall have previously deposited an additional sum into the Escrow Account pursuant to this Section 8.09.

          (b) The Purchaser and the Seller acknowledge and agree that notwithstanding anything to the contrary contained in this Agreement or any Ancillary Agreement, if the Unresolved Tax Position Amount (as defined in Section 7.03 of the Separation Agreement) is deposited into the Escrow Account pursuant to Section 8.09(a) of this Agreement, the Purchaser shall not seek, and shall cause the Company not to seek, payment of the Adjusted Tax Position

78

Amount from any Distributed Subsidiary unless and until it has sought a distribution of the Unresolved Tax Position Amount pursuant to Section 8.09(a).

          SECTION 8.10. Exclusive Remedies. (a) Except with respect to the matters set forth in Section 5.03 (Confidentiality) and Section 5.08 (Non-Competition) or breaches of the representations and warranties set forth in Section 3.25 or 4.07, the provisions of this Article VIII, Section 10.01 and Section 10.14 hereof set forth the exclusive rights and remedies of the parties hereto to seek or obtain damages or any other remedy or relief whatsoever from any party with respect to matters arising under or in connection with this Agreement and the transactions contemplated hereby.

          (b) For the avoidance of doubt, nothing in this Agreement or any Ancillary Agreement shall require the Seller and the Distributed Subsidiaries, on the one hand, and the Purchaser, the Company and the Acquired Subsidiaries, on the other hand, to indemnify another party or parties more than once for the same Tax Liability.

ARTICLE IX

81

          SECTION 10.03. Public Announcements. Upon execution of this Agreement, the parties shall jointly issue a press release, as mutually agreed upon by them. The Seller shall not make, or cause to be made, any press release or public announcement in respect of this Agreement or the transactions contemplated hereby or otherwise communicate with any news media without the prior written consent of the Purchaser, which shall not be unreasonably withheld, unless otherwise required by Law. The Seller hereby consents to the Purchaser’s filing of this Agreement and the Ancillary Agreements with the Securities and Exchange Commission.

          SECTION 10.04. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

          SECTION 10.05. Entire Agreement. This Agreement and the Ancillary Agreements constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between the Seller and the Purchaser with respect to the subject matter hereof and thereof.

          SECTION 10.06. Assignment. This Agreement may not be assigned by operation of law or otherwise without the express written consent of the Seller and the Purchaser (which consent may be granted or withheld in the sole discretion of the Seller or the Purchaser); provided, however, that the Purchaser may assign this Agreement or any of its rights hereunder to one or more Affiliates of the Purchaser without the consent of the Seller and provided further, however, that such an assignment by the Purchaser shall not release the Purchaser from any of its obligations hereunder.

          SECTION 10.07. Amendment. This Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, the Seller and the Purchaser or (b) by a waiver in accordance with Section 10.08.

          SECTION 10.08. Waiver. Any party to this Agreement may (a) extend the time for the performance of any of the obligations or other acts of the other party, (b) waive any

82

inaccuracies in the representations and warranties of the other party contained herein or in any document delivered by the other party pursuant hereto or (c) waive compliance with any of the agreements of the other party or conditions to such party’s obligations contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of either party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

          SECTION 10.09. No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person, including any union or any employee or former employee of the Seller, any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement.

          SECTION 10.10. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York applicable to contracts executed in and to be performed in that State. All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in any New York federal court sitting in the Borough of Manhattan of The City of New York, provided, however, that if such federal court does not have jurisdiction over such Action, such Action shall be heard and determined exclusively in any New York state court sitting in the Borough of Manhattan of The City of New York. Consistent with the preceding sentence, the parties hereto hereby (a) submit to the exclusive jurisdiction of any federal or state court sitting in the Borough of Manhattan of The City of New York for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto and (b) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement or the transactions contemplated by this Agreement may not be enforced in or by any of the above-named courts.

          SECTION 10.11. Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated by this Agreement. Each of the parties hereto hereby (a) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it has been induced to enter into this Agreement and the transactions contemplated by this Agreement, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.11.

This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

          SECTION 10.14. Specific Performance. The parties hereto acknowledge and agree that any breach of the terms of this Agreement would give rise to irreparable harm for which money damages would not be an adequate remedy and accordingly the parties hereto agree that, in addition to any other remedies, each party hereto shall be entitled to enforce the terms of this Agreement by a decree of specific performance without the necessity of proving the inadequacy of money damages as a remedy.

          SECTION 10.15. Tax Disclosure Authorization. Notwithstanding anything herein to the contrary, the parties (and each Affiliate and person acting on behalf of any party) agree that each party (and each employee, representative, and other agent of such party) may consult any tax advisor regarding the transactions’ tax treatment and tax structure (as such terms are used in Sections 6011 and 6112 of the Code and the Regulations thereunder) contemplated by this Agreement and, from and after the date of execution of this Agreement (or if earlier, the date of public announcement of this Agreement, or public announcement of discussions between the parties relating to the transactions contemplated by this Agreement), may disclose to any and all persons, without limitation of any kind, the transactions’ tax treatment and tax structure contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) relating to such tax treatment and tax structure, except to the extent necessary to comply with any applicable federal or state securities laws.
