(ii) If the Purchase Price as finally determined in accordance with Section 2.4 is greater than 110% of the sum of the high point of the ranges set forth in the D&T Valuation Report for CSL/US, JRH/Australia and JRH/UK, then the portion of the Purchase Price equal to the difference between the Purchase Price and 110% of such sum shall be allocated among the Purchased Securities in accordance with the methodology used by Deloitte & Touche in the preparation of the D&T Valuation Report. If the Purchase Price as finally determined in accordance with Section 2.4 is less than 90% of the sum of the low point of the ranges set forth in the D&T Valuation Report for CSL/US, JRH/Australia and JRH/UK, then the Purchase Price shall be allocated among the Purchased Securities in accordance with the methodology used by Deloitte & Touche in the preparation of the D&T Valuation Report.

(a) (i) CSL shall deliver to Buyer at least six Business Days prior to the Closing a closing statement (the “Estimated Closing Purchase Price Certificate”) setting forth the calculation of CSL’s good faith estimate of the Purchase Price (the “CSL Price Estimate”), including a detailed presentation of the calculations of the items comprising Closing Net Cash and Closing Net Working Capital, which calculations shall be prepared using accounting methods, policies, practices, procedures, classifications and estimation methodologies as set forth on Schedule 2.4(a) (“Accounting Procedures”). Buyer shall deliver to CSL in writing no later than three Business Days after its receipt of Estimated Closing Purchase Price Certificate a notice (an “Estimated Purchase Price Objection Notice”) reasonably describing (giving consideration to the time period and information

available to Buyer for such review) any good faith objections it may have to the CSL Price Estimate as set forth on the Estimated Closing Purchase Price Certificate and its reasons therefor together with the calculation of Buyer’s good faith estimate of the Purchase Price (the “Buyer Price Estimate”), including a detailed presentation of its calculations of the items comprising Closing Net Cash and Closing Net Working Capital, which calculations shall be prepared using the same Accounting Procedures as were used to determine the Reference Working Capital, as set forth on Schedule 2.4(a).

(ii) If Buyer fails to deliver to CSL an Estimated Purchase Price Objection Notice within three Business Days of its receipt of the Estimated Closing Purchase Price Certificate, then the CSL Price Estimate as set forth on the Estimated Closing Purchase Price Certificate shall be the “Closing Date Purchase Price Amount” for purposes of Section 2.3(b).

(iii) If Buyer delivers to CSL an Estimated Purchase Price Objection Notice within three Business Days of its receipt of the Estimate Closing Purchase Price Certificate, then CSL and Buyer shall work together in good faith to resolve any disagreements relating to the calculation of the Estimated Purchase Price set forth on the Estimated Closing Price Certificate. Each of CSL and Buyer shall also have the opportunity to revise their respective Price Estimates, including any revisions necessary to bring that difference to less than U.S. $10,000,000, and no such revisions shall in any event constitute an admission against interest, admission that the CSL Price Estimate or Buyer Price Estimate delivered in accordance with Section 2.4(a)(i) was not calculated in good faith, or estoppel or waiver of any rights, arguments, positions taken in such process, nor shall any such revision limit the positions that may be taken by the parties in the final determination of Purchase Price in accordance with Section 2.4(b). If CSL and Buyer are unable to resolve any disputes as to the calculations of the Purchase Price as set forth on the Estimated Closing Purchase Price Certificate and Estimated Purchase Price Objection Notice, then the “Closing Date Purchase Price Amount” for purposes of Section 2.3(b) shall be determined as follows:

(A) if the difference between the CSL Price Estimate and the Buyer Price Estimate is U.S. $10,000,000 or less, then the “Closing Date Purchase Price Amount” for purposes of Section 2.3(b) shall be the average of the CSL Price Estimate and Buyer Price Estimate; and

(B) if the difference between the CSL Price Estimate and the Buyer Price Estimate is greater than U.S. $10,000,000, then the “Closing Date Purchase Price Amount” for purposes of Section 2.3(b) shall be the lower of the CSL Price Estimate and the Buyer Price Estimate, and an amount equal to the difference between the CSL Price Estimate and the Buyer Price Estimate shall be deposited by Buyer into an escrow account in accordance with Section 2.5.

(b) As promptly as practicable, but in any event within 60 days following the Closing Date, CSL shall prepare (in consultation with ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, if he shall then be employed by the Operating Companies or another designee of Buyer if ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ is not then employed by the Operating Companies) and deliver to Buyer a Closing Date Balance Sheet and CSL’s certificate, derived from the Closing Date Balance Sheet, setting forth in reasonable detail the

calculation of the Closing Net Cash and the Closing Net Working Capital and the difference, if any, between the Purchase Price as determined in accordance with the Closing Date Balance Sheet and the Closing Date Purchase Price Amount delivered in accordance with Section 2.3(b) (the “Closing Purchase Price Adjustment Certificate”). The Closing Date Balance Sheet and the Closing Purchase Price Adjustment Certificate shall be prepared in accordance with the Accounting Procedures, and shall be delivered together with a report thereon of Ernst & Young (“CSL’s Accountants”) that such statement fairly presents in all material respects the Closing Net Cash and the Closing Net Working Capital of the Companies determined in conformity with such Accounting Procedures. Notwithstanding anything to the contrary set forth herein, in all events the same Accounting Procedures shall be used to calculate both the Reference Working Capital and the Closing Net Working Capital as finally determined in accordance with this Section 2.4, and if for any reason the Accounting Procedures used to calculate the Closing Net Working Capital as finally determined in accordance with this Section 2.4 are required by GAAP applied on a consistent basis to differ from the Accounting Procedures that were used to calculate the Reference Working Capital in accordance with the procedures set forth on Schedule 2.4(a), then the Reference Working Capital shall be re-calculated using the same Accounting Procedures as are used to determine the Closing Net Working Capital as finally determined in accordance with this Section 2.4, and the adjustment to the Purchase Price contemplated by Section 2.1(b)(ii) shall be calculated based on the Reference Working Capital as so recalculated; provided, however, that the Sellers shall not realize an increase in the Purchase Price as a result of any failure properly to apply the Accounting Procedures, including GAAP applied on a consistent basis, in originally calculating the Reference Working Capital. In connection with the preparation of the Closing Purchase Price Adjustment Certificate, Buyer shall and shall cause the Companies to provide the Sellers and the Sellers’ authorized representatives with full access to the books, records, facilities and employees of the Company and to cooperate fully with the Sellers and the Sellers’ authorized representatives, including providing on a timely basis all information necessary or useful in preparing the Closing Purchase Price Adjustment Certificate and require Company employees to assist the Sellers and the Sellers’ authorized representatives in the preparation of the Closing Purchase Price Adjustment Certificate.

(c) CSL shall afford Buyer timely access to all supporting documents and work papers used in the preparation of the Closing Date Balance Sheet and the Closing Purchase Price Adjustment Certificate and the calculation of the Closing Net Cash amounts and the Closing Net Working Capital.

(d) Buyer may dispute any amounts reflected on the Closing Purchase Price Adjustment Certificate or the calculation of Closing Net Cash or the Closing Net Working Capital, but only on the basis of its belief that the amounts reflected on the Closing Purchase Price Adjustment Certificate were not arrived at in accordance with this Agreement or resulted from a mistake of fact, failure to comply with the Accounting Procedures, including GAAP applied on a consistent basis, or other inaccuracy contained in the Closing Date Balance Sheet or elsewhere; provided, however, that Buyer shall have notified CSL in writing of each disputed item, specifying the amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute, within 60 days of CSL’s delivery to Buyer of the Closing Purchase Price Adjustment Certificate. In the event of such a dispute, CSL and Buyer shall work together in good faith to resolve any disagreements. If CSL and Buyer are unable to reach a resolution within 30 days after receipt by CSL of Buyer’s written notice of dispute, CSL and Buyer shall submit the items then remaining in dispute for resolution to an independent accounting firm of international reputation mutually acceptable to them) (the “Independent Accounting Firm”), which shall, within 30 days after such

submission, determine and report to the CSL and Buyer upon such remaining disputed items, and such report shall be final and binding on all of the parties. The fees and disbursements of the Independent Accounting Firm shall be allocated evenly between CSL and Buyer. In acting under this Agreement, the Independent Accounting Firm shall be entitled to the privileges and immunities of arbitrators.

(e) The Closing Purchase Price Adjustment Certificate and the calculation of the Purchase Price (including the adjustments contemplated by Section 2.1(b)(i) and (ii)) shall be deemed final for the purposes of this Section 2.4 upon the earliest of (i) the failure of Buyer to notify CSL of a dispute within 60 days of CSL’s delivery of the Closing Purchase Price Certificate to Buyer, (ii) the resolution of all disputes pursuant to Section 2.4(d) by Buyer and CSL, (iii) the resolution of all disputes, pursuant to Section 2.4(d) by the Buyer’s Accountants and CSL’s Accountants, and (iv) the resolution of all disputes pursuant to Section 2.4(d) by the Independent Accounting Firm. Buyer will inform Deloitte & Touche of the final Purchase Price promptly after its determination, and in no event later than five Business Days after it is deemed final pursuant to this Section 2.4(e).

(f) If the final calculation of the Purchase Price pursuant to Section 2.4(b)-(e) is less than the Closing Date Purchase Price Amount paid to Sellers in accordance with Section 2.3(b), (i) Sellers shall pay to Buyer an amount equal to the absolute value of such difference and (ii) Buyer shall be entitled to receive all amounts held in the Escrow Account. In the event that the final calculation of the Purchase Price pursuant to Section 2.4(b)-(e) is more than the Closing Date Purchase Price Amount paid to Sellers in accordance with Section 2.3(b), then Buyer shall pay to CSL, on behalf of all of the Sellers, the absolute value of such difference (and Buyer may use amounts held in the Escrow Account, if any, for such purpose). Any payment made in accordance with this Section 2.4(f), and any payment made in accordance with Article VIII, Article IX or any other indemnification provision contained herein, shall, to the extent not prohibited by applicable Law, be deemed for all tax, accounting and other reporting purposes as an adjustment to the Purchase Price.

(g) Any payment made pursuant to Section 2.4(f) shall be made (i) within ten (10) Business Days after the Closing Purchase Price Certificate and the calculation of the Purchase Price (including the adjustments contemplated by Section 2.1(b)(i) and (ii)) are deemed final in accordance with Section 2.4(e), and (ii) by causing such payments to be credited in immediately available funds to such bank account or accounts as may be designated by the receiving party in accordance with wire transfer instructions delivered in writing not less than two Business Days prior to transfer (and in the case of payments to be made to CSL, in accordance with the instructions used to deliver the Closing Date Purchase Price Amount). Other than payments made from the Escrow Account (which shall bear interest as set forth in the Escrow Agreement), any payment to be made pursuant to Section 2.4(f) shall bear interest from and including the Closing Date but excluding the date of payment at a rate of 5¹/4%. Such interest shall be payable at the same time as the payment to which it relates and shall be calculated daily on the basis of a year of 365 days and the actual number of days for which interest is due.

2.5 Escrow. If in accordance with Section 2.4(a) Buyer is obligated to deposit an amount into an escrow account, then the parties shall enter into an Escrow Agreement in the form of Schedule 2.5 hereto (the “Escrow Agreement”) with Commerce Bank, N.A., a national banking association (the “Escrow Agent”) and Buyer shall deposit such amount with the Escrow Agent to be maintained in accordance with the Escrow Agreement (the sums so deposited with the Escrow Agent and all amounts earned thereon being referred to as the “Escrow Amount”)

(a) Buyer shall not, and shall cause any Company not to, at any time prior to the 61st day following the Closing Date, without fully complying with the notice and other requirements of the U.S. Worker Adjustment and Retraining Notification Act of 1988 (“WARN Act”) or without fully complying with the collective consultation requirements under the (UK) Trade Union and Labour Relations (Consolidation) ▇▇▇ ▇▇▇▇ (“TULCRA”), if applicable, effectuate (i) a “plant closing” (as defined in the WARN Act) affecting any site of employment or one or more facilities or operating units within any site of employment of any Company, or (ii) a “mass layoff” (as defined in the WARN Act) affecting any site of employment of any Company. Buyer also shall not, and shall cause any Company not to, without fully complying with the notice and other requirements of the applicable Law in Australia, the UK, and/or the European Union, effectuate modifications to the facilities or reduce or change the terms of employment of the Companies’ employees in Australia and the UK, as applicable.

(b) If Buyer takes any action within 180 days after the Closing Date which independently, or in connection with any reduction in the size of the Companies’ work force occurring within the ninety-day period prior to the Closing Date, could be construed as a “plant closing” or “mass layoff,” as those terms are defined in the WARN Act or any action covered in the United Kingdom by TULCRA, Buyer shall be solely responsible for providing any notice required by the WARN Act or under TULCRA and for making payments, if any, and paying all penalties and costs, if any, which may result from any failure to provide such notice.

5.10 Intentionally Omitted.

5.11 Employee Benefit Plans.

(a) As of the Closing Date, all employees of the Companies shall cease to participate in any Company Plan where employees other than the employees of the Companies also participate. Upon the Buyer’s request, the Companies and the Sellers shall terminate any Company Plans that cover only employees of the Companies prior to the Closing Date. All participants and former participants in any Company Plan that is an employee pension benefit plan as defined in Section 3(2) of ERISA shall become fully vested in their benefits under such employee pension benefit plan. As promptly as reasonably practicable after the Closing Date, the Buyer shall, or shall cause the Companies to, enroll such persons who were employees of the Companies immediately prior to the Closing Date and who continue to be employees of the Companies or the Buyer following the Closing Date, other than ▇▇▇▇▇▇ ▇▇▇▇▇▇ (“Continuing Employees”) and employees of Sellers set forth on Section 5.11(e) of the Seller Disclosure Schedule (“Transferred Employees”) in the Buyer’s employee benefit plans for which such employees are eligible (“Buyer Plans”) on the same terms as which the Buyer’s similarly situated employees participate. However, Buyer shall provide hourly Continuing Employees and Transferred Employees of the Companies with long term disability benefits through the close of the current fiscal year (June 30, 2005) under the existing Company welfare benefit plans providing such benefits. Subject to the requirements of applicable law, Buyer shall cause Continuing Employees and Transferred Employees to be given credit under each Buyer Plan in which such employees are eligible to participate, as determined above, for all service with the Sellers, the Companies, and their Affiliates for all purposes to the extent permitted under each Buyer Plan and except to the extent such service credit would result in the duplication of benefits. Notwithstanding anything herein to the contrary, this Section shall not operate to duplicate any benefit provided to any Continuing Employee or to fund any such benefit. Although Continuing Employees and Transferred Employees shall accrue vacation leave according to the vacation policy of the Buyer, each Continuing Employee and Transferred Employee shall be grandfathered with respect to their annual vacation leave earned as of the Closing Date. Notwithstanding the foregoing, with respect to Australian Employees (but not including non- employee directors or former employees) and CSL Secondees, Buyer shall comply with Schedule C (the “Australian Benefit/Employment Addendum”), and with respect to UK Employees (but not including non-employee directors or former employees) and employees currently employed by JRH/US, this Section 5.11(a) shall be subject to the additional provisions of Section 5.11(d). Except as otherwise provided in this Agreement, Buyer shall assume responsibility for continuation coverage compliance under COBRA for Continuing Employees and Transferred Employees.

(b) If the Continuing Employees or the Transferred Employees become eligible to participate in any medical, dental or other welfare plan of Buyer or the Companies, Buyer shall cause such plan to (i) waive any preexisting condition limitations for conditions covered under the applicable Company Plans or Seller employee benefit plans covering such employees at the Closing Date and (ii) honor any deductible and out-of-pocket expenses incurred by the employees and their beneficiaries under the applicable Company Plans or Seller employee benefit plans during the portion of the calendar year in which the Closing occurs that precedes the Closing Date. If the Continuing Employees or Transferred Employees become eligible to participate in a group term life insurance plan maintained by Buyer, or the Companies, to the extent permitted thereunder, Buyer shall cause such plan to waive any medical certification for such employees up to the amount of coverage the employees had under the life insurance plan covering such employees at the Closing

Date (but subject to any limits on the maximum amount of coverage under Buyer’s, Companies’ life insurance plan). In addition, prior to the Closing Date, Sellers shall cause the accounts of any employee of the Operating Companies participating in a flexible benefit plan to be transferred into a separate and comparable plan (which may be Buyer’s Plan if directed by Buyer) and Buyer shall assume the obligations under such plan on the Closing Date.

(c) The Buyer shall provide to any Continuing Employee and Transferred Employee whose employment is involuntarily terminated without cause or made redundant on or before the first anniversary of the Closing Date with severance benefits in accordance with the terms and conditions of the Companies’ severance policy as amended and restated December 2004, including, if applicable, the minimum severance benefit of twelve (12) weeks (“Normal Severance Benefit”) unless such employee is a party to a retention or employment agreement providing severance benefits. If a Continuing Employee and/or Transferred Employee is a party to a retention or employment agreement previously disclosed by Seller to Buyer, which provides for severance benefits, Buyer shall provide severance benefits in accordance with the terms of such agreement.

(d) With respect to the U.S. Company Plan that is a qualified retirement plan under Sections 401(a) and 401(k) of the Code, prior to the Closing Date (the “Company 401(k) Plan”) and if requested by Buyer, Sellers shall effect a termination or partial termination and cause the account balance of each Continuing Employee and Transferred Employee to be 100% vested. Buyer shall provide retirement benefits to Continuing Employees and Transferred Employees under Buyer’s Plans. Buyer shall also designate a tax-qualified defined contribution plan of the Buyer (“Buyer 401(k) Plan”) that either (i) currently provides for the receipt from Continuing Employees and Transferred Employees of “eligible rollover distributions” (as such term is defined under Section 402 of the Code) or (ii) shall be amended as soon as practicable following the Closing Date to provide for the receipt from such eligible rollover distributions. If Buyer requests a termination of the Company 401(k) Plan, each Continuing Employee and Transferred Employee who is a participant in the Company 401(k) Plan shall be given the opportunity to receive a distribution of his or her account balance and shall be given the opportunity to elect to “roll over” such account balance to the Buyer 401(k) Plan, subject to and in accordance with the provisions of such plan and applicable Law. Either of CSL/US or JRH/US, as applicable, shall provide Buyer with copies of any personnel and other records pertaining to the Transferred Employees and such records of any agent or representative of CSL/US or JRH/US, as applicable, pertaining to the Transferred Employees and the Company 401(k) Plan as Buyer may reasonably request in order to administer and manage the accounts and assets rolled over to the Buyer 401(k) Plan. With respect to UK Employees (but not including non-employee directors or former employees), Buyer shall participate, or provide participation, in the Scottish Widows Scheme or provide a private retirement benefit of comparative scope.

(e) Except as otherwise contemplated by Section 5.11(e) of the Seller Disclosure Schedule, at or prior to the Closing, the Companies will continue the employment of all of the employees of Sellers employed in the JRH Business.

(f) As soon as practicable following the Closing Date, Sellers shall pay to each Transferred Employee who participates in the Companies’ GoalSharing Plan (the “GoalSharing Plan”), a cash amount equal to the pro rata bonus amount accrued under the GoalSharing Plan for the current bonus period through the Closing Date. Through the close of the current fiscal year

(June 30, 2005), Buyer shall maintain a bonus program that is economically comparable on an aggregate basis to the GoalSharing Plan, provided that Buyer shall have the sole discretion to determine performance goals, bonus targets and payout of any bonus amounts.

(g) Buyer shall assume on the Closing Date all liabilities associated with the provision of medical benefits after retirement to ▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇ pursuant to any existing or former policy, plan or contractual obligation of the Companies.

(h) With the exception of any applicable severance payments and outplacement services, CSL shall on the Closing Date assume all obligations of the Companies to all employees of the Companies with respect to the payment of retention, completion-of-project and any other incentive bonuses, the payment of which is contingent upon the occurrence of the Closing hereunder. CSL shall also pay all costs associated with the termination or any change in the employment terms of ▇▇▇▇▇▇ ▇▇▇▇▇▇ and, to the extent that such costs are borne by the Companies, CSL shall indemnify and hold harmless the Companies for all such costs, including, but not limited to, those costs related to any litigation or anticipated litigation and those costs related to the Contract of Service and Non-Competition and Confidentiality Agreement dated as of 1 June 1999 by and between JHR/US and ▇▇▇▇▇▇ ▇▇▇▇▇▇, as amended on 1 September 2004 and as further amended by a Second Amendment to Contract of Service and Non-Competition and Confidentiality Agreement dated as of 12 January 2005. CSL shall after the date hereof and prior to Closing make available to Buyer at reasonable times during regular business hours employees of the Companies with whom Buyer wishes to meet to enable Buyer to discuss such individuals’ continued employment with the Companies following the Closing.

(i) With respect to the JRH Biosciences Incentive Compensation Policy dated 15 August 2003, and any comparable sales commission arrangement applicable to Australian, European or U.K. employees, Buyer agrees to maintain a sales commission program that is economically comparable on an aggregate basis to the Companies current arrangements through the close of the current fiscal year (June 30, 2005) provided that Buyer shall have sole discretion to determine the applicable parameters under which sales commissions shall become payable and the terms of any payout.

(j) Sellers shall retain all obligations under the CSL Limited Performance Rights Plan and the CSL Senior Executive Share Ownership Plan and for handling outstanding shares purchased under the Global Employee Share Plan. To the extent permissible without an amendment to any plan, Sellers will agree to review the possibility of the termination of any disposal restrictions on shares purchased by employees of Sellers employed in the JRH business and so advise Buyer prior to Closing.

(k) Sellers hereby agree to indemnity Buyer and each of Buyer’s affiliates and to defend and hold Buyer and each of Buyer’s affiliates harmless from and against any and all losses (including but not limited to reasonable attorney’s fees and other costs of defense incurred in any action) arising out of or with respect to any Company employees with respect to events arising before the Closing and which relate to any promise, arrangement, program or employee benefit plan sponsored by Sellers or the Companies for the benefit of Company employees. Nothing in this paragraph (k) will oblige the Sellers to indemnify Buyer or any of Buyer’s affiliates in respect of any manner relating to Australian Employees or CSL Secondees, and the parties agree that all such indemnification obligations in respect of Australian Employees and CSL Secondees shall arise only under the Australian Benefit/Employment Addendum.

5.12 Contacts with Suppliers. Customers and Other Parties. Prior to the Closing Date, and subject to such reasonable limitations as the Sellers shall deem necessary and subject to applicable Law, the Sellers shall permit, and shall cause each Company to permit, and arrange for discussions and meetings between Buyer and suppliers and customers and employees of the Companies as requested by Buyer, and shall cooperate in such discussions and meetings.

(c) To the extent permitted by Law, no director, officer, employee, affiliate (including officers and employees of such affiliate), agent, adviser, representative or their successors and assigns of Buyer will be liable to any Seller in respect of any act, matter or thing that occurred before, at or after Closing and related to this Agreement or the transactions contemplated by this Agreement, other than an act of fraud by that person.

(d) This Section 5.13 is intended to be for the benefit of, and shall be enforceable by, the Seller Indemnified Parties and the Buyer Indemnified Parties referred to herein, their heirs and personal representatives and shall be binding on Buyer and the Sellers and their respective successors and assigns.

5.14 Further Assurances. At any time and from time to time on or after the Closing Date, at the other party’s request and without further consideration, each of the parties hereto shall promptly execute and deliver all such further agreements, certificates, instruments and documents and perform such further actions as such other party may reasonably request, in order to fully consummate the transactions contemplated by this Agreement and fully carry out the purposes and intent of this Agreement.

5.15 Change of Name.

(a) The Buyer shall as soon as practicable after Closing Date and in any event within 30 days after the Closing Date, change the name, logos and any other identifications used on printed or other materials owned or used by the Companies or otherwise so as to cease using the expression “CSL” or any substantially similar expression; provided, however, that all Products labeled with “CSL” may be kept and sold by Buyer for 180 days after the Closing Date without relabeling.

Notwithstanding anything to the contrary in this Agreement, this Agreement may be terminated and the transactions contemplated by this Agreement abandoned at any time prior to the Closing as follows (any exercise by CSL of its rights to terminate this Agreement in accordance with this Section 7.1 shall be binding upon and effective as to each of the Sellers):

(a) by the mutual written consent of Buyer and CSL;

(a) This Agreement (other than the agreements of the parties hereto contained in this Section 7.2 and Article X which shall survive the termination of this Agreement) shall become null and void and of no effect with no liability on the part of any party hereto (or of any of its Affiliates, directors, officers, employees, equity holders, agents, legal and financial advisors or other representatives); provided, however, that if this Agreement is terminated by a party because of a breach of the Agreement by the other party or because one or more of the conditions to the terminating party’s obligations under this Agreement is not satisfied as a result of the other party’s failure comply with its obligations under this Agreement, the terminating party’s right to pursue all legal remedies will survive such termination unimpaired.

(b) Buyer will promptly redeliver to Sellers or destroy, in accordance with the terms of the Confidentiality Agreement (which Confidentiality Agreement shall remain in full force and effect notwithstanding the termination of this Agreement), all Evaluation Material (as such term is defined in the Confidentiality Agreement) whether obtained before or after the execution of this Agreement. Also, for one year after such termination, Buyer shall not, and cause each of its Subsidiaries not to, directly or indirectly, solicit any individual who immediately prior to the Closing Date was an employee of any Company; provided, however, general advertisements and other forms of general solicitations for employment shall not be deemed a violation of this Section 7.2(b).

ARTICLE VIII

INDEMNIFICATION

8.1 Indemnification by CSL.

(a) From and after the Closing and subject to the provisions of this Article VIII (other than Section 8.2), CSL shall, or shall cause each of the other Sellers to, indemnify Buyer and and its directors, officers, employees, affiliates (including officers and employees of such affiliates), agents, representatives and their successors and assigns (collectively, the “Buyer Indemnified Parties”) and hold Buyer Indemnified Parties harmless from and against any loss, suit, liability, claim, actual, indirect or consequential damage, charge, cost or expense (including reasonable legal fees and expenses) (collectively, “Losses”), actually incurred by Buyer Indemnified Parties, to the extent relating to or arising out of any of the following:

(i) any breach of any representation or warranty of CSL set forth in this Agreement or certificates or other documents delivered in connection with the Closing;

(ii) any breach of any covenant of any of the Sellers set forth in this Agreement;

(iii) all obligations and liabilities of CSL/US arising on or before the Closing Date, or arising after the Closing Date on account of or relating to facts, circumstances and conditions existing on or before the Closing Date, (provided that the indemnity obligations under this Section 8.1(a)(iii) shall not apply to obligations or liabilities of JRH/US that arise against or are chargeable to CSL/US on the basis of any doctrine allowing the parent of a legal entity to be liable for its subsidiaries’ obligations (e.g., “piercing the corporate veil”) unless such obligations otherwise are indemnified by Sellers under this Article VIII);

(iv) all obligations and liabilities of the Companies arising on account of or relating to (A) the ZLB Divestiture and any obligation or liability of CSL/US arising by reason of CSL/US’ ownership of ZLB Bioplasma, Inc. or ZLB Holdings, Inc., whether before or after the completion of the ZLB Divestiture, (B) CSL/US’ obligations arising under the Umbrella Sale Deed dated December 16, 2003 among CSL, CSL/US, CSL (New Zealand) Limited, Pfizer Inc. and certain other Persons (pursuant to which CSL/US sold all of the issued and outstanding Capital Securities of Biocor Animal Health, Inc.) (the “Biocor Sale”), or (C) CSL/US’ ownership of Biocor Animal Health, Inc., whether before or after the completion of the Biocor Sale;

(v) payments to be made in connection with the By-Prod Agreement other than those included in Closing Indebtedness;

(vi) any obligation or liability of the Companies by reason of any Product Liability Claim arising as a result of acts of any Company that occurred prior to the Closing Date; and

(vii) any obligation or liability of the Companies by reason of the Debt Releases.

(b) CSL shall not be required to indemnify Buyer Indemnified Parties, and shall not have any liability under Section 8.1(a)(i) or (ii), as follows; provided, however, the limits set forth in Section 8.1(b)(i), (ii) and (iii) shall not apply to CSL’s indemnification obligation with respect to the representations and warranties set forth in Sections 3.1, 3.2, 3.3, 3.4, 3.18, 3.19 and 3.35, the covenants set forth in Article II, any Sections of Article V other than Sections 5.5, 5.6 and 5.15, Article IX, or any other covenant on the part of Sellers to pay or reimburse money to Buyer Indemnified Parties, and provided further, the limits set forth in Section 8.1(b)(i), (ii) and (iii) shall not apply to CSL’s indemnification obligation with respect to the representations and warranties set forth in Section 3.20, which indemnification obligations are the subject of Section 8.1(c):

(i) unless the aggregate of all Losses exceeds on a cumulative basis an amount equal to U.S.$2,000,000 (or equivalent value), and then only to the extent of any such excess;

(ii) for any individual occurrences, events, circumstances, acts or omissions where the Loss relating thereto is less than U.S.$50,000 (or equivalent value) and any such occurrences, events, circumstances, acts or omissions shall not be taken into account for purposes of clauses (i) or (iii) of this Section 8.1(b); or provided, for the avoidance of doubt, that whenever multiple situations exist at the same Real Property that give rise to a Loss or Losses based on the same or similar set of related actions, inactions, facts or circumstances, such multiple situations shall be aggregated to constitute a single “individual item” for purposes of the preceding clause (for example, the failure to maintain proper records for all inventory lots would not constitute a separate item for each lot of inventory, but would be deemed a single individual item giving rise to a single Loss in the aggregate amount of all such failures);

(iii) for Losses in the aggregate in excess of U.S.$111,000,000 (or equivalent value).

(c) CSL shall not be required to indemnify Buyer Indemnified Parties, and shall not have any liability under clause (i) of Section 8.1(a), with respect to the representations and warranties set forth in Section 3.20 (and disclosure, if any, set forth in Section 3.20 of the Seller Disclosure Schedule shall not relieve CSL of its indemnification obligations with respect to Section 3.20 for those matters disclosed in Section 3.20 of the Seller Disclosure Schedule) as follows:

(i) for any individual occurrence, event, circumstance, act or omission where the Loss relating thereto is less than U.S.$50,000 (or equivalent value), and any such occurrence, event, circumstance, act or omission shall not be taken into account for purposes of clauses (ii) and (iii) of this Section 8.1(c); provided, for the avoidance of doubt, that whenever multiple situations exist at the same Real Property that give rise to a Loss or Losses based on the same or similar set of related actions, inactions, facts or circumstances, such multiple situations shall be aggregated to constitute a single “individual item” for purposes of the preceding clause (for example, the failure to obtain more than one sample as required by the same discharge permit at the same Real Property that leads to one notice of violation by a Governmental Authority would not constitute a separate item for each cited violation within the notice of violation but would be deemed a single individual item giving rise to a single Loss in the aggregate amount of all such failures);

(ii) for more than 90% of each Dollar of Loss incurred by Buyer Indemnified Parties with respect to the representations and warranties set forth in Section 3.20; or

(iii) for an amount in excess of $55,500,000 (or equivalent value) in the aggregate.

(d) Notwithstanding any provision of this Agreement to the contrary, with respect to any Losses arising by reason of any Releases of Hazardous Substances or violations of Environmental Laws at the Swampbridge Road Facility or the JRH Business operations thereat, including the presence or removal of underground storage tanks from such Real Property and any Releases from such underground storage tanks, Seller’s indemnity to Buyer Indemnified Parties under Section 8.1(c) shall not be limited in amount.

(e) CSL shall have no liability hereunder with respect to the representations and warranties set forth in Section 3.7 to the extent that the risk of any liability or obligation that is the subject of a claim for the breach of the representations and warranties made in Section 3.7 is otherwise allocated by this Agreement.

8.2 Indemnification by Buyer.

(a) From and after the closing and subject to the provisions of this Article VIII, Buyers shall indemnify Sellers and its directors, officers, employees, affiliates (including officers and employees of such affiliates), agents, representatives and their successors and assigns (collectively, the “Seller Indemnified Parties”) and hold Seller Indemnified Parties harmless from and against all Losses actually incurred by Seller Indemnified Party to the extent relating to or arising out of the following:

(i) any breach of any representation or warranty of Buyer set forth in this Agreement;

(ii) any breach of any covenant of Buyer set forth in this Agreement; and

(iii) all debts, liabilities and other obligations of the Companies other than in respect of those matters described in Section 8.1(a).

(b) Buyer shall not be required to indemnify any Seller Indemnified Party, and shall not have any liability under clause (ii) of Section 8.2(a), for any individual occurrences, events, circumstances, acts or omissions where the Loss relating thereto is less than U.S.$50,000 (or equivalent value); provided, however, that the limitation set forth in this Section 8.2(b) shall not apply with respect to the Losses arising in connection with Buyer’s breach of any of its covenants set forth in Article II, any Sections of Article V other than Sections 5.5, 5.6 and 5.15, Article IX, any other covenant on the part of Buyer to pay or reimburse money to Seller Indemnified Party, and any such occurrences, events, circumstances, acts or omissions shall not be taken into account for purposes of clauses (i) of this Section 8.2(b).

8.3 Calculation of Losses.

(a) The amount of any Loss for which indemnification is provided under this Article VIII or Article IX shall be net of any amounts recovered by the Indemnified Party or its Affiliates under insurance policies after adjustment for future increases in premiums on other amounts payable by the Indemnified Party or reimbursement provided by any Governmental Entity or other Person with respect to such Loss, and shall be adjusted to take account of the actual amount of any Tax benefit or Tax detriment realized by the Indemnified Party or any Affiliate or group of Affiliates of such Indemnified Party arising from the incurrence or payment of any such Loss. In computing the amount of any such Tax benefit or Tax detriment, the Indemnified Party shall be deemed to recognize and receive items of loss deduction or credit resulting from the Loss giving rise to indemnification upon actual recognition of such loss deduction or credit; further, to the extent that the Indemnified Party cannot utilize any Tax benefit with respect to a Loss in the Tax period of such Loss or in the Tax period any indemnification payment for such Loss is received, the Indemnified Party shall reimburse the Indemnifying Party for the amount of such Tax benefit upon actual utilization of such Tax benefit by the Indemnified Party. Such payment for reimbursement shall be made to the Indemnifying Party within ten Business Days of the utilization of such Tax benefit.

(b) Notwithstanding anything to the contrary contained herein, no indemnification shall be provided for under this Article VIII or Article IX in respect of any special or punitive damages (other than punitive damages sought, awarded or otherwise imposed in any Third-Party Claim).

(c) Notwithstanding anything to the contrary herein, the parties agree that indemnifiable Losses (a) may include indirect and consequential damages so long as such damages (i) were reasonably foreseeable and (ii) proximately resulted from the events and circumstances giving rise to the Losses, (b) exclude punitive damages (but include punitive damages sought, awarded or otherwise imposed in any Third-Party Claim) and (c) exclude Taxes payable by an Indemnified Party as a result of any indemnification payment under this Agreement being treated by

the relevant Taxing Authority as income; provided that in no event shall CSL be obligated to indemnify Buyer with respect to indirect or consequential damages in excess of U.S.$25,000,000 (other than in respect of indirect and consequential damage arising with respect to a breach of the representations and warranties set forth in Sections 3.1, 3.2, 3.3, 3.4, 3.18 and 3.35, as to which breaches there will be no limit on the amount of indirect or consequential damages that may be recovered by Buyer).

8.4 Termination of Indemnification. The Indemnifying Party’s obligations to indemnify and hold harmless the Indemnified Party shall terminate when the applicable representation, warranty or covenant under which such claim for indemnification arises terminates pursuant to Section 8.7; provided, however, that such obligation to indemnify and hold harmless shall not terminate with respect to any item as to which the Indemnified Party shall have in good faith before the expiration of the applicable period, previously made a claim by delivering a notice of such claim (in accordance with the terms of Section 8.5) to the Indemnifying Party.

8.5 Procedures Relating to Indemnification.

(a) In order for any Indemnified Party to be entitled to any indemnification provided for under this Agreement arising out of a claim made by any Person against the Indemnified Party (a “Third-Party Claim”), such Indemnified Party must notify the Indemnifying Party in writing (and in reasonable detail) of the Third-Party Claim promptly (but in no event more than 10 days) following receipt by such Indemnified Party of notice of the Third-Party Claim. The failure to so notify shall not relieve the Indemnifying Party of any liability it (or they) may have to such Indemnified Party if such failure does not prejudice the Indemnifying Party. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, promptly following the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third-Party Claim.

(b) If a Third-Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if the Indemnifying Party acknowledges its responsibility to indemnify the Indemnified Party as provided in this Agreement with respect to Losses incurred by the Indemnified Party with respect to such Third-Party Claim, the Indemnifying Party may elect to assume control of the defense of such Third-Party Claim, at the Indemnifying Party’s expense with counsel selected by the Indemnifying Party; provided, however, that such counsel is not reasonably objected to by the Indemnified Party. Should the Indemnifying Party so elect to assume control of the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel (not reasonably objected to by the Indemnifying Party), at its own expense, separate from the counsel employed by the Indemnifying Party (it being understood that the Indemnifying Party shall control such defense). The Indemnified Party shall be entitled to reimbursement for all costs, fees and expenses (including the fees and expenses of counsel employed by the Indemnified Party) for any period during which the Indemnifying Party has not assumed the defense thereof (other than during any period in which the Indemnified Party shall have failed to give notice of the Third-Party Claim as provided above). If the Indemnifying Party chooses to defend or prosecute a Third-Party Claim, all the Indemnified Parties shall, at the Indemnifying Party’s cost, cooperate in all material respects in the defense or prosecution thereof. Such

cooperation at the Indemnifying Party’s cost shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably requested by the Indemnifying Party or that are reasonably relevant to such Third-Party Claim, and making employees available on a mutually convenient basis during normal business hours to provide additional information and explanation of any material provided hereunder. Whether or not the Indemnifying Party assumes the defense of a Third-Party Claim, (x) the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge such Third-Party Claim without the Indemnifying Party’s prior written consent, not to be unreasonably withheld, and (y) the Indemnifying Party shall not, without the Indemnified Party’s prior written consent, admit any liability with respect to, or settle, compromise or discharge, such Third-Party Claim on a basis that would result in the imposition of a judgment that would restrict the future activity or conduct of the Indemnified Party or any subsidiary or affiliate thereof.

(c) In the event any Indemnified Party should have a claim against the Indemnifying Party under Section 8.1 that does not involve a Third-Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim promptly (but in no event more than 30 days) following discovery by the Indemnified Party of such claim to the Indemnifying Party. The failure to so notify shall not relieve the Indemnifying Party of any liability it may have to such Indemnified Party if such failure does not prejudice the Indemnifying Party. If the Indemnifying Party disputes its liability with respect to such claim, prior to any party’s seeking any relief at law, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute for a period of at least 60 days after the Indemnifying Party’s receipt of the Indemnified Party’s notice.

(d) Any valid claim for indemnification under this Agreement shall describe the claim in reasonable detail, include copies of any material written evidence thereof and indicate the estimated amount of such claim.

(e) Each Indemnified Party shall make commercially reasonable efforts to mitigate any claim of liability that an Indemnified Party asserts under this Article VIII. In the event that an Indemnified Party shall fail to make such commercially reasonable efforts to mitigate any claim or liability, then notwithstanding anything else to the contrary contained herein, CSL shall not be required to indemnify any Indemnified Party for any Loss that could reasonably be expected to have been avoided if the Indemnified Party had made such efforts. All costs of mitigation and all damages to an Indemnified Party related thereto shall be the liability of the Indemnifying Party.

8.6 Additional Procedures Relating to Environmental Matters.

(a) Each party agrees that it shall not and shall use its commercially reasonable efforts to ensure that each of its Affiliates shall not, directly or indirectly, communicate orally or in writing with any Governmental Entity relating to any actual or potential liability under Environmental Law for which the other party may be responsible under this Agreement; except for any Legitimate Business Purpose or to the extent that Buyer or any Seller believes in good faith that such communication is required by any Environmental Law and except in response to an inquiry or other request for information from any Governmental Entity. For the purposes hereof, “Legitimate Business Purpose” shall mean work (i) to maintain or achieve compliance with an Environmental Law, (ii) to respond to a Release that violates or would violate applicable Environmental Law, (iii) to minimize offsite exposure from a Release, (iv) in response to threatened or actual enforcement

action, investigation, proceeding or claim by a Governmental Entity or third person, or (v) to reasonably maintain, improve, expand, remove or replace equipment, utilities, buildings or other improvements.

(b) To the extent Buyer seeks indemnification for any Loss arising out of or associated with an Environmental matter, Buyer will provide CSL with written notice of each such Loss and the opportunity to assume the lead in conducting negotiations with any third party and to investigate or remedy any such matter if Sellers acknowledge responsibility to indemnify Buyer with respect to Losses connected with such matter as provided in this Agreement.

(c) Regardless of which of Buyer or CSL assumes the lead role (the “Lead Party”; and the other of Buyer or CSL that does not assume the lead role being referred to as the “Non-Lead Party”) in addressing or defending against any environmental matter regarding which CSL has an indemnification obligation arising under this Agreement, Buyer and CSL shall follow the following procedural requirements:

(i) In undertaking Remedial Action with respect to Releases of Hazardous Substances on, under or arising from the Real Property or at properties currently owned by third parties, and except as otherwise provided in Section 8.6(c)(iii) and (iv);

(A) To the extent reasonably necessary to pursue Remedial Actions, the Lead Party shall retain qualified, independent environmental consultant(s), which consultant(s) shall be subject to the Non-Lead Party’s approval (such approval not be unreasonably withheld, conditioned or delayed);

(B) The Lead Party shall provide to the Non-Lead Party, for the Non-Lead Party’s review and comment, drafts of any proposed work plans, reports or other submissions for any Remedial Action that the Lead Party intends to deliver or submit to the appropriate Governmental Entity prior to said submission (in the event a Governmental Entity is not involved in the Remedial Action, this requirement shall apply to any work plans the Lead Party desires to implement). The Non-Lead Party shall have 14 days to provide comments to the Lead Party regarding any such draft submissions, unless such review period is not reasonably possible within the schedule or due date established by the Governmental Entity, in which case the Lead Party shall endeavor to provide the Non-Lead Party as much time as reasonably possible under the schedule (up to the 14 days) for its review. Such review and comments shall be at the Non-Lead Party’s own expense. The Lead Party shall give good faith consideration to the Non-Lead Party’s comments regarding such draft submissions;

(C) The Lead Party shall promptly provide copies to the Non-Lead Party of all written notices, final submissions, final work plans and final reports;

(D) The Lead Party shall provide the Non-Lead Party with reasonable advance notice of all planned meetings and telephone conferences with applicable Governmental Entity(ies) and the Non-Lead Party, at its own expense, shall have the right to send representatives to attend and participate in such meetings;

(E) The Non-Lead Party may, at its own expense, hire its own consultants, attorneys or other professionals to monitor the Remedial Action, including any field work undertaken by the Lead Party, and the Lead Party and Non-Lead Party shall share with each other the results of all such field work; and

(F) Notwithstanding the above, the Non-Lead Party shall not take any actions that shall unreasonably interfere with the Lead Party’s Performance of the Remedial Action.

(ii) With respect to any claims for indemnification related violations of applicable Environmental Law, other than matters that involve a Remedial Action with respect to the Release of Hazardous Substances on the Real Property:

(A) Buyer shall be the Lead Party for all Remedial Actions under this Section 8.6(c)(ii); provided, that Buyer will provide CSL with the opportunity to be the Lead Party for all Remedial Actions under this Section 8.6(c)(ii) in connection with violations of applicable Environmental Law at the Swampbridge Road Facility if Sellers acknowledge responsibility to indemnify Buyer with respect to Losses connected with such matters as provided in this Agreement.

(B) To the extent reasonably necessary to pursue Remedial Actions, the Lead Party shall retain qualified, independent environmental consultant(s), which consultant(s) shall be subject to the Non-Lead Party’s approval (such approval not to be unreasonably withheld, conditioned or delayed);

(C) The Lead Party shall have the right, consistent with applicable Environmental Law, to determine and implement the appropriate Remedial Actions to correct any failures to comply with applicable Environmental Law in effect as of the Closing Date. The Lead Party shall consult with the Non-Lead Party in all material respects in connection with undertaking such Remedial Actions, shall provide the Non-Lead Party with copies of all correspondence submitted to and received by any Governmental Authorities with respect to such matters and shall provide the Non-Lead Party with a reasonable opportunity to comment on any material submissions to Governmental Entities with respect to such matter, including Remedial Action proposals;

(D) Without limiting the foregoing, CSL shall not be obligated to indemnify Buyer for costs incurred in connection with implementation of Remedial Actions that are in excess of the costs that would be incurred to achieve compliance with applicable Environmental Law in effect as of the Closing Date in the most reasonably cost effective manner; provided that the selected Remedial Action for purposes of this section shall be sufficient to allow the Companies to operate the JRH Business at the effected Real Property in a manner and at a level of production that is consistent with the operation of such Real Property at the time of Closing. To the extent that the Buyer chooses to implement a Remedial Action that goes beyond the standard set forth above, including, without limitation, one that allows for an expansion in operations at a property or that is required to achieve compliance with Environmental Law that does not become applicable to a property until after the Closing Date, the CSL shall not be responsible for the additional or excess costs associated with such corrective action.

(E) For the avoidance of doubt, Remedial Actions contemplated by this Section 8.6(b)(ii) shall not include any Remedial Action related to Releases of Hazardous Substances on, under or arising from the Real Property.

(iii) Where CSL assumes the role of Lead Party, CSL shall, and shall ensure that its representatives will, conduct all Remedial Action in a manner that (a) is in accordance with the professional standards practiced by reputable professions in environmental consulting or other applicable professions; (b) takes all reasonable steps to protect from damage all existing improvements on the Real Property; and (c) takes all reasonable steps to prevent interference with the use of the Real Property, the operation of the JRH Business on the Real Property, and the regulatory compliance of the JRH Business. If CSL requires access to any Real Property to conduct a Remedial Action, CSL and Buyer will renegotiate and enter into a mutually agreeable access agreement to provide CSL such access to the Real Property. CSL shall, and shall ensure that its representatives will, use reasonable efforts to preserve the Real Property in the condition in which it existed prior to commencement of the work. Further where CSL assumes the role of Lead Party, Buyer shall cause the Companies to assign to CSL and enable CSL to assert and prosecute in the name and on behalf of the Companies any claims, cross claims or other rights any of the Companies may have against third parties who have or may have any liability for the violation of Environmental Laws or Releases of Hazardous Substances regarding which CSL is indemnifying Buyer hereunder. If CSL is the Lead Party or if Buyer is the Lead Party but Sellers indemnify Buyer with respect to Losses connected with such matter, then 90% of any recovery obtained from any third party with respect to such matter, whether pursuant to any claim, cross claim or other right, shall redound to the benefit of CSL, and 10% of such recovery shall redound to the benefit of Buyer.

(iv) If, after the Closing Date, Buyer or any Company is required to sign and/or certify any document required by an Environmental Law or a Governmental Entity to achieve compliance with any Environmental Law or to effect a Remedial Action, Buyer shall, and shall cause the Companies, to consult with CSL with respect to the form and content of such document; provided, that Buyer shall have sole discretion as to the final form and content of such document. In no event shall Buyer’s or any Company’s signing and/or certifying, or failure to or delay in signing and/or certifying, to any such document extend the duration of CSL’s indemnification obligations hereunder. Buyer shall provide a final copy of all such documents to CSL.

(d) Each Seller’s obligations to indemnify the Buyer Indemnified Parties for any Environmental Loss shall be deemed satisfied (i) so long as the remedy complies with applicable Environmental Laws as applied to the real property in question based upon its use at the time of the Closing Date and (ii) upon receipt of a no further action letter or its equivalent from the appropriate Governmental Entity or written acknowledgment from the Governmental Entity that the work is complete, if such Governmental Entity has taken jurisdiction over the matter.

8.7 Survival. All representations and warranties contained in this Agreement shall survive until the second anniversary of the Closing Date; provided, however, that (i) the representations and warranties set forth in Sections 3.1, 3.2, 3.3 and 3.4 shall survive until the tenth anniversary of the Closing Date, (ii) the representations and warranties set forth in Section 3.19 shall survive 90 days after the expiration of the statute of limitations period applicable thereto (including

any extension and tolling), and (iii) representations and warranties set forth in Sections 3.20 and 3.35 shall survive until the fifth anniversary of the Closing Date, except that the representations and warranties set forth in Section 3.20 with respect to the Real Property and JRH Business operations at the Swampbridge Road Facility shall survive until the sixth anniversary of the Closing Date. CSL shall have no obligation to indemnify Buyer with respect to the matters disclosed in Section 3.20 of the Seller Disclosure Schedule (other than the matters at the Swampbridge Road Facility) with respect to claims made therefor after the fifth anniversary of the Closing Date; and CSL shall have no obligation to indemnify Buyer with respect to the matters at the Swampbridge Road Facility disclosed in Section 3.20 of the Seller Disclosure Schedule with respect to claims made therefor after the sixth anniversary of the Closing Date. All of the covenants, agreements and obligations of the parties contained in this Agreement to be performed after the Closing Date shall, unless a different period is expressly provided for herein, survive until fully performed or fulfilled, unless non-compliance with such covenants, agreements or obligations is waived in writing by the party or parties entitled to such performance.

8.8 Right to Indemnification Not Affected by Knowledge. The right to indemnification, payment of damages or any other remedy based on representations, warranties, covenants or any other obligations under this Agreement will not be affected by any investigation conducted with respect to such matters by Buyer nor any knowledge acquired by it (or capable of being acquired by it) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date.

8.9 Coordination With Tax Covenant. In the event any provision of this Article VIII with respect to Tax matters is inconsistent with any provision of Article IX, the provisions of Article IX shall control.

ARTICLE IX

TAX INDEMNIFICATION

9.1 CSL Tax Indemnity. From and after the Closing Date and subject to the provisions of this Article IX, CSL agrees to indemnify Buyer against the following:

(a) all Taxes or liabilities for Taxes imposed on or with respect to the Companies for any taxable period or portion thereof that ends on or before the Closing Date;

(b) all Taxes or liabilities for Taxes of any Person (other than the Companies) imposed on any of the Companies as a transferee or successor, by contract or pursuant to Law, which Taxes relate to an event or transaction occurring before the Closing;

(c) all Taxes or liabilities for Taxes arising by reason of any of the Restructuring Transactions, the Debt Releases, the Retained Earnings Dividend and transactions contemplated by Section 5.7 of this Agreement;

(d) all Taxes or liabilities for Taxes arising pursuant to the provisions of s179 Taxation of Chargeable Gains ▇▇▇ ▇▇▇▇ as a result of the transfer of the shares in JRH/UK; and

(e) all Losses relating to any Taxes or liabilities for Taxes in Sections 9.1(a) through 9.1(d).

Except for the representations set forth in Section 3.19 and the indemnification therefore provided in Article VIII, this Article IX is the sole provision governing Tax matters and indemnities therefor under this Agreement. The provisions of Section 9.6(e) shall apply to any indemnification for breach of a representation set forth in Section 3.19 in lieu of the provisions of Section 8.5.

9.2 Excluded Tax Liabilities. CSL shall not be liable to indemnify Buyer for Taxes or any liabilities for Taxes under this Article IX, or under Article VIII pursuant to a breach of a representation or warranty set forth in Section 3.19, if and to the extent:

(a) such Taxes or liabilities for Taxes are attributable to any business operations or transactions of Buyer or its Affiliates, including the Companies, after the Closing, except to the extent governed by Section 9.5;

(b) such Taxes or liabilities for Taxes are reflected on the Closing Date Balance Sheet (excluding any deferred Tax items) and included in the calculation of the Closing Net Cash;

(c) such Taxes or liabilities for Taxes arise in a taxable period (or portion thereof) beginning after the Closing Date as a result of a reduction in or elimination of a Tax loss carryforward of the Companies from a period (or portion thereof) ending on or before the Closing Date to a period (or portion thereof) beginning after the Closing Date;

(d) Buyer or any of its Affiliates (including the Companies), receive payment for such Taxes or liabilities for Taxes as a result of any indemnity, contribution or other similar payment from any third party with respect thereto; it being understood that Buyer, its Affiliates or the Companies shall be obligated to assert a right of indemnification or contribution from a third party only to the extent of their actual knowledge of such right without independent investigation thereof and such assertion would not be unduly burdensome;

(e) such Taxes or liabilities for Taxes arise as a direct result of a change in legislation that is announced and enacted after the Closing Date but has an effective date on or prior to the Closing Date (for purposes of this Section 9.2(e), the item disclosed on Section 3.7(1) of the Seller Disclosure Schedule shall be deemed announced);

(f) solely with respect to JRH/UK, any relief arising in respect of any event occurring or any income, profits or gains earned, accrued or received on or before the Closing Date (other than a relief which has previously been utilized and other than a relief which was taken into account in the calculation of Closing Net Cash) is available or is for no consideration and at no cost (including any Tax cost) to the Buyer or any of its Affiliates, including the Companies, made available to relieve or mitigate the Taxes or liability for Taxes in respect of which CSL or any of the Sellers is liable under this Agreement and so that, for this purpose any relief arising in respect of a taxable period that begins on or before the Closing Date and ends after the Closing Date shall be apportioned on a time basis, unless some other basis is more reasonable having regard, inter alia, to the principles set out in Section 9.5;

(g) solely with respect to JRH/UK, such Taxes or liabilities for Taxes arise or are increased wholly or mainly in consequence of any failure by Buyer or its Affiliates to comply with this Agreement;

(h) solely with respect to JRH/UK, such Taxes or liabilities for Taxes would not have arisen but for any claim, election, surrender or disclaimer made, or notice or consent given, or any other thing done, after the Closing Date (other than one the making, giving or doing of which was specifically taken into account in the calculation of Closing Net Cash) under, or in connection with, the provisions of any enactment or regulation relating to Tax by the Buyer or any of its Affiliates and otherwise than at the direction of CSL;

(i) solely with respect to JRH/UK, such Taxes or liabilities for Taxes would not have arisen but for the failure or omission by Buyer or any of its Affiliates, otherwise than at the direction of CSL, to make any claim, election, surrender or disclaimer, or give any notice, or consent or do any other thing, under, or in connection with, the provisions of any enactment or regulation relating to Tax after the Closing Date (collectively, the “Tax Claims”), the anticipated making, giving or doing of which was specifically taken into account in the calculation of Closing Net Cash; provided, however, the details of all Tax Claims, the anticipated making, giving or doing of which have been or are to be taken into account in the calculation of Closing Net Cash have been either set forth on Section 3.19 of the Seller Disclosure Schedule or provided to Buyer by written notice no later than 60 days following the Closing Date; provided, further, CSL shall notify Buyer in writing of the details of all Tax Claims, the anticipated making, giving or doing of which have been or are to be taken into account in the calculation of Closing Net Cash, within a reasonable time before any such Tax Claims are to be made, gave or done in order for Buyer to properly evaluate such Tax Claims and make, give or do such Tax Claims; or

(j) such Taxes or liabilities for Taxes arise in connection with any entity classification election made for JRH/UK or JRH/Australia pursuant to Section 5.8.

9.3 Buyer Tax Indemnity. Buyer and its Affiliates, including the Companies following the Closing Date, shall indemnify and hold harmless CSL and its Affiliates for and against all Taxes attributable to any business operations or transaction of Buyer or its Affiliates, including the Companies after Closing, imposed on any of CSL and its Affiliates for a taxable period (or portion thereof) beginning after the Closing Date (calculated in accordance with Section 9.5).

9.4 Due Dates. Indemnification payments by any Indemnifying Party for any Taxes under this Article IX shall be made within ten Business Days following written notice by the Indemnified Party; provided that no Indemnifying Party shall be required to make any payment earlier than two Business Days before such Taxes are due and payable to a Taxing Authority. In case of any Contest under Section 9.6(e) of this Agreement, payment of such Tax to the Taxing Authority shall be considered due no earlier than five Business Days following the date a final determination is made by the Tax Authority or a court of competent jurisdiction that such Tax is due and payable. Notwithstanding the foregoing, in the event that any immediate payment of any asserted Taxes or liabilities for Taxes is required by Law to be paid prior to the right to contest such Taxes or liabilities for Taxes, the Indemnifying Party shall pay such disputed Taxes or liabilities for Taxes within the requisite period of time required by Law and the Indemnifying Party shall retain the right to contest such Taxes or liabilities for Taxes notwithstanding that such Taxes or liabilities for Taxes have been paid. In such case, the Indemnified Party shall cooperate with the Indemnifying Party in the manner set forth in Section 9.6.

9.5 Proration of Certain Taxes. For purposes of this Agreement, in case of any Taxes that are payable with respect to a taxable period that begins before the Closing Date and ends

after the Closing Date, the portion of any such Taxes that are allocable to the portion of the period ending on the Closing Date shall be: (i) deemed equal to the amount that would be payable if the taxable year ended on the Closing Date in the case of Taxes that are either (x) Taxes on income or (y) imposed in connection with any sale or other transfer of property (real or personal, tangible or intangible) (other than conveyances pursuant to this Agreement) and (ii) in the case of any other Tax, deemed to equal the amount of such Taxes for the entire period multiplied by a fraction in which the numerator is the number of days in the portion of the period ending on the Closing Date and the denominator is the number of days in the entire period.

9.6 Tax Cooperation. Each of CSL, Buyer and their respective Affiliates shall cooperate as set forth below with respect to Tax matters for time periods ending on or before the Closing Date.

(a) Tax Cooperation in General. Each of Buyer and its Affiliates and CSL shall cooperate fully, as and to the extent reasonably requested by the other, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes.

(b) Information. In addition to such other information as may be required to be provided by Buyer under this Agreement, Buyer shall provide to CSL such information (including copies of relevant documents and work papers) as CSL may reasonably request in order for CSL to comply with its Tax obligations, including reporting requirements, filing any Tax Return, amended Tax Return or claim for refund, or participating in or conducting any audit or other proceeding in respect of Taxes.

(c) Preparation of Tax Returns. CSL shall have the exclusive right to prepare and file (or cause to be prepared and filed) or control the preparation and filing of all Tax Returns relating to the Companies that are due on or before the Closing Date or that relate to any taxable period ending on or before the Closing Date. With respect to any Tax Return so prepared by CSL after the Closing Date, CSL shall provide Buyer with a copy of such completed return, and a statement at least 30 calendar days prior to the due date (including any extension thereof) for the filing of such return, and Buyer shall have the right to review such return and statement prior to the filing of such return. Buyer and CSL agree to consult and to attempt in good faith to resolve any issues arising as a result of the review of such return and statement; provided that any objection that is not resolved by Buyer and CSL shall be submitted to an independent accounting firm of international reputation acceptable to CSL and Buyer for resolution, whose determination shall be binding on Buyer and CSL (and any expenses shall be borne as provided in Section 9.6(f)). Buyer and CSL shall have joint control over the preparation and filing of any Tax Returns relating to a taxable period for which Taxes are prorated under Section 9.5. Buyer and CSL agree to consult and to attempt in good faith to resolve any issues arising as a result of the preparation and filing of such returns and statements; provided that any objection that is not resolved by Buyer and CSL shall be submitted to an independent accounting firm of international reputation acceptable to CSL and Buyer for resolution, whose determination shall be binding on Buyer and CSL (and any expenses shall be borne as provided in Section 9.6(f)). All such Tax Returns shall be prepared in a manner consistent with practices followed in prior years with respect to similar Tax Returns except for changes required by applicable Law.

(d) Retention of Books and Records. Each of Buyer and CSL shall retain all returns, schedules, and work-papers and all material records or other documents relating to Tax

matters of the Companies for the taxable periods referenced in this Article IX until four years following the expiration of the applicable statute of limitations (and, to the extent notified by such other party, any extensions thereof), shall give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, at such time, if such other party so requests, shall allow the other party to take possession of such books and records.

(e) Contest. CSL may elect to direct, through counsel of its own choice and at its own expense, any audit, claim for refund and administrative or judicial proceeding involving any asserted Tax liability with respect to which indemnity may be sought against CSL under this Article IX (any such audit, claim for refund or proceeding relating to an asserted Tax Liability is referred to herein as a “Contest”); provided that CSL informs Buyer of the progress and substantive aspects of any such Contest, including providing Buyer with all written materials relating to the Contest received from the relevant Taxing Authorities. If CSL elects to direct a Contest, then CSL shall, within forty-five calendar days of receipt of Buyer’s notice of asserted Tax liability, notify Buyer of its intent to do so, and Buyer shall cooperate and shall cause each of the Companies to cooperate, in each phase of such Contest. If CSL does not elect to direct the Contest or fails to notify Buyer of its election to direct the Contest as herein provided, Buyer may pay, compromise or contest such asserted Tax liability in accordance with prudent business standards, as if no indemnification were granted hereunder; provided that Buyer may not settle or compromise such asserted Tax liability without the prior written consent of CSL (which consent to settlement or compromise shall not be unreasonably withheld, delayed or conditioned). Buyer shall inform CSL of the progress and the substantive aspects of any Contest Buyer directs, including providing CSL with all written materials relating to the Contest received from relevant Taxing Authorities. In any event, CSL may participate, at its own expense, in any Contest controlled by Buyer. If CSL chooses to direct the Contest as provided above, Buyer shall promptly empower and shall cause its Affiliates promptly to empower (by power of attorney and such other documentation as may be necessary and appropriate) the designated representatives of CSL to represent Buyer in the Contest insofar as the Contest involves an asserted Tax liability with respect to which indemnity may be sought against CSL under this Article IX; provided, however, Buyer shall be entitled to participate in any such Contest and CSL shall not agree to any settlement or compromise without Buyer’s consent if in the Buyer’s discretion such settlement or compromise reasonably may have an adverse impact on the Tax liability of any of the Companies, Buyer or its Affiliates in a period beginning after the Closing Date; provided further Buyer and CSL shall jointly control Contests with respect to any taxable period for which Taxes would be prorated under Section 9.5 and neither CSL nor Buyer shall agree to any settlement of any Contest without the other Party’s consent (which shall not be unreasonably withheld, conditioned or delayed).

(f) Cooperation Costs. Each of Buyer and CSL agree that any expenses incurred by a party or its Affiliates in connection with the cooperation described in this Section 9.6 shall be the responsibility of such party and its Affiliates incurring the cost and no reimbursement shall be sought from the party requesting such cooperation.

(g) Transfer Taxes. (i) All sales, use, transfer, documentary, stamp, registration and other similar Taxes that are payable in connection with the transactions contemplated by this Agreement shall be borne by the party responsible therefor under applicable Law. The party required by applicable Law to file any Tax Returns and other documentation with respect to any such Taxes shall prepare and file such Tax Returns and the Buyer and Sellers shall each, and shall each cause its Affiliates to, cooperate in the timely preparation and filing of, and join in the execution of, any such Tax Returns and other documentation.

(ii) Notwithstanding anything to the contrary in this Agreement, Buyer shall be responsible for and shall pay any stamp duty or similar tax payable in respect of the transfer of the Capital Securities of JRH/UK and JRH/Australia pursuant to this Agreement.

9.7 Survival. The right to indemnification under this Article IX shall expire 90 days after the expiration of the applicable statute of limitations (including any extensions or tolling thereof).

9.8 Refunds. Except to the extent taken into account in determining the Purchase Price or subject to Section 9.2(d) of this Agreement, CSL shall be entitled to all refunds of Taxes, plus any interest thereon received from a Taxing Authority, with respect to the Companies relating to taxable periods or portions thereof ending on or before the Closing Date, and Buyer shall, upon receipt of any refund by Buyer or the Companies, pay over to CSL any such refund or the amount of any such benefit within five Business Days of the receipt thereof. Buyer shall, if CSL so requests, cause the Companies to file for and obtain any refunds or equivalent amounts to which CSL is entitled to under this Section 9.8 except to the extent that in the Buyer’s discretion such claim for refund reasonably may have an adverse impact on the Tax liability of any of the Companies, Buyer or its Affiliates in a period beginning after the Closing Date. Buyer shall permit CSL to control (at CSL’s expense) the prosecution of any such refund claimed, and shall cause the relevant Company to authorize by appropriate power of attorney such persons as CSL shall designate to represent such entity with respect to such refund claimed.

9.9 Tax Covenants.

(a) Except as required by Law, neither Buyer nor any Affiliate of Buyer shall amend, refile or otherwise modify, or cause or permit the Companies to amend, refile or otherwise modify, any accounting method, election or Tax Return relating in whole or in part to the Companies with respect to any taxable year or period, or portion thereof, ending on or before the Closing Date without the prior written consent of CSL (which consent shall not be unreasonably withheld, delayed or conditioned) if such amendment, refilling or modification would reasonably be expected to have an adverse impact on the Tax liability of any of the Companies in a period ending on or before the Closing Date.

(b) To the extent permitted by Law, neither Buyer nor any Affiliate of Buyer shall carry back, or cause or permit the Companies to carry back, for federal, state, local or non-U.S. Tax purposes to any taxable year or period, or portion thereof, ending on or before the Closing Date any operating losses, net operating losses, capital losses, Tax credits or similar items arising in a taxable period beginning after the Closing Date without a prior written consent of CSL (which consent shall not be unreasonably withheld, delayed or conditioned) if carrying back such item would reasonably be expected to have an adverse impact on the Tax liability of any of the Companies in a period ending on or before the Closing Date.

(c) As of the Closing Date, the Companies shall be released from all tax-sharing agreements or similar arrangements with respect to or involving the Companies, and Buyer and its Affiliates (including the Companies) shall have no further liability with respect thereunder.

(d) Buyer will procure that JRH/UK continues to qualify as a trading company within the meaning of Schedule 7AC to the Taxation and Chargeable Gains ▇▇▇ ▇▇▇▇ for a period of 30 days following the Closing Date.

(e) Buyer shall, at the direction in writing of CSL/UK, procure that JRH/UK accepts and takes all action necessary for any surrender of group relief pursuant to section 402 of the Income and Corporation Taxes Act 1988 from CSL/UK (of any of its Affiliates) to JRH/UK where such surrender would operate to reduce or eliminate a liability for Taxes of JRH/UK for which any Seller is liable under this Agreement (and where such surrender is permitted by law).

ARTICLE X

OTHER PROVISIONS

10.1 Amendment and Waiver. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by Sellers and Buyer, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

10.2 Fees and Expenses. Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated by this Agreement are consummated, the parties hereto shall bear their own respective expenses (including, but not limited to, all compensation and expenses of counsel, financial advisors, consultants, actuaries and independent accountants) incurred in connection with this Agreement and the transactions contemplated hereby.

10.3 Binding Agreement: Assignment. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Neither party to this Agreement may assign this Agreement or any of its rights or obligations under this Agreement without the express prior written consent of the other party hereto; provided, however, that the Buyer shall have the right to transfer and assign the rights hereunder to one or more of its Affiliates so long as Buyer remains obligated with respect hereto and such assignment in no way delays the consummation of the transaction contemplated hereby; and provided, further, that Buyer in any event shall have the right to transfer and assign the right to acquire the shares of JRH/Australia to an Affiliate formed under the laws of Australia so long as the additional filings as identified in Section 6.1(a)(ii) of the Seller Disclosure Schedule are made in accordance with, and within the time periods specified in, the procedures set forth in Section 5.3. Any purported assignment in violation of this Agreement is void.

10.4 Entire Agreement. This Agreement (including all Exhibits and Schedules hereto) and any agreement between Buyer and Sellers making specific reference to this Section 10.4 contain the entire agreement between the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, except for the Confidentiality Agreement which will remain in full force and effect for the term provided for therein.

10.5 Remedies. Except in the case of fraud (as to which there shall be no limit on the remedies available to or recoverable by Buyer or Sellers on account thereof) and with respect to covenants contained in Article II and Article V (which, if breached, the parties agree would result in irreparable injury for which the non-breaching party would not have an adequate remedy at law and would therefore be entitled to injunctive relief), the sole and exclusive remedy of Buyer and Sellers after the Closing with respect to any Losses relating to this Agreement or any of the transactions contemplated hereby shall be pursuant to the indemnification provisions set forth in Article VIII, Article IX and Schedule C. In furtherance of the foregoing, Buyer and Sellers hereby waive, from and after the Closing, any and all rights, claims and causes of action (other than claims or causes of action based on fraud or with respect to covenants contained in Article II and Section 5.2) any of them may have against any other party hereto, or any of the parties’ respective Affiliates, directors, officers, employees or equity owners, arising under or based upon any Law or arising under or based upon common law or otherwise (except pursuant to the indemnification provisions set forth in Article VIII, Article IX and Schedule C).

10.6 No Third-Party Beneficiaries. Except as set forth in Section 5.13, nothing in this Agreement, express or implied, is intended to confer upon any Person other than Buyer, Sellers, or their respective successors or permitted assigns, any rights or remedies under or by reason of this Agreement.

10.7 Schedules. The inclusion of any matter in any specific Section or Subsection of the Seller Disclosure Schedule or Buyer Disclosure Schedule (including all schedules and exhibits thereto) shall not be deemed to be disclosed for any other Section or Subsection of such Seller Disclosure Schedule or Buyer Disclosure Schedule unless included or referenced in such other Section or Subsection. Inclusion in the Seller Disclosure Schedule or Buyer Disclosure Schedule shall expressly not be deemed to constitute an admission by Buyer, Sellers, or the Companies, or otherwise imply, that any such matter is material or creates a measure for materiality for the purposes of this Agreement.

10.8 Conversion of Amounts into U.S. Dollars. Whenever used in this Agreement, “$” or “Dollars” refers to U.S. Dollars unless the text expressly indicates otherwise. To the extent that any amount payable in U.S. Dollars under this Agreement is based on an amount denominated in a currency other than U.S. Dollars, that amount shall be converted into U.S. Dollars using the U.S. Dollar exchange rate for such currency as published in the United States edition of The Wall Street Journal on the Business Day immediately preceding the date on which such amount is payable. Any amount referenced herein in a currency other than U.S. Dollars shall be deemed a reference to the amounts of U.S. Dollars into which such amount of currency is convertible using the U.S. Dollar exchange rate for such currency as published in the U.S. edition of the United States edition of The Wall Street Journal on the Business Day immediately preceding the date as of which such amount is to be measured in accordance with this Agreement.

10.9 GST Issues.

(a) Unless otherwise expressly stated, all amounts payable under this Agreement are expressed to be exclusive of GST. If GST is payable on a Taxable Supply, the amount payable for that Taxable Supply will be the amount expressed in this Agreement plus GST.

(b) Without limiting paragraph (a) above, if an amount payable under this Agreement is calculated by reference to a Loss incurred by a party, then the Loss must be reduced by the amount of any Input Tax Credit to which that party is entitled in respect of that Loss. A party will be assumed to be entitled to a full Input Credit unless it demonstrates that its entitlement is otherwise prior to the date on which payment must be made.

(c) A party receiving a Taxable Supply (the “Recipient”) is not required to pay an amount on account of GST under paragraph (a) above to the party making the Taxable Supply (the “Supplier”) until the Supplier has provided the Recipient with a Tax Invoice in respect of that Taxable Supply.

(d) In this Section 10.9, the terms “GST”, “Input Tax Credit”, “Loss”, “Tax Invoice” and “Taxable Supply” have the meaning given in section 195-1 of the (Australia) A New Tax System (Goods and Services Tax) ▇▇▇ ▇▇▇▇ (Cth).

10.10 Interpretation; Headings; Etc. The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and do not limit or otherwise affect any of the provisions hereof. Where a reference in this Agreement is made to an Article, Section, Schedule or Exhibit, such reference is to an Article, Section, Schedule or Exhibit to this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” All words used in this Agreement shall be construed to be of such number and gender as the context requires or permits.
