 33

material respects and in material compliance with the requirements of the HSR Act or such other Competition Laws. Each of Buyer and Aon agrees to file any additional information requested by such Administrative Authorities agencies under the HSR Act
or such other Competition Laws, to make available to the other such information as each of them may reasonably request relative to its business, assets and properties as may be required of each of them to file such additional information and to take

(including via telephone or conference call) in respect of any filings, investigation or other inquiry unless it consults with the other in advance (to the extent it has reasonable notice thereof and the opportunity to so consult) and, to the extent
permitted by such Administrative Authority, gives the other the opportunity to attend and participate at such meeting. 
 (e) In furtherance
and not in limitation of the foregoing, Buyer shall use its reasonable best efforts to take any and all steps necessary to avoid or eliminate impediments or objections, if any, that may be asserted with respect to the transactions contemplated by
this Agreement under any antitrust, competition or trade regulatory Requirements of Law of any Administrative Authority so as to enable the parties hereto to close the transactions contemplated hereby as promptly as practicable, including using its
reasonable best efforts to defend through litigation on the merits any claim asserted in court by any party in order to avoid entry of, or to have vacated or terminated, any decree, order or judgment (whether temporary, preliminary or permanent)
that would prevent the consummation of the Closing. Notwithstanding the foregoing, in no event shall Buyer be obligated to (i) accept any condition or requirement imposed by an Administrative Authority relating to the acquisition, ownership or
operation of the Company and the Subsidiaries by Buyer which, either alone or together with all such other conditions or requirements, materially and adversely affects the benefits, taken as a whole, which Buyer would otherwise receive from the

 ADDITIONAL AGREEMENTS

 Section 8.1 Tax Matters. (a) Liability for Taxes. (i) Aon shall be liable for and pay, and
pursuant to Article XI (and subject to the provisions thereof but not subject to the limitations in Section 11.1(a)) agrees to indemnify and hold harmless each Buyer Group Member, the Company and the Subsidiaries against, any and
all Taxes (A) imposed on the Company or any Subsidiary pursuant to Treasury Regulation Section 1.1502-6 or similar provision of state or local law as a result of the Company or any Subsidiary having been a member of the Aon consolidated
group, (B) imposed on the Company, any Subsidiary, or any Buyer Group Member as a result of the restructuring described in Section 8.8 of this Agreement, (C) imposed on the Company or any Subsidiary, or for which the Company or
any Subsidiary may otherwise be liable, for any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date, including
Section 338 Taxes and any Taxes imposed on the transactions contemplated by the Sterling Agreement or (D) imposed on the Company or any 

  

 39 

 
Subsidiary as a result of any breach of warranty or misrepresentation under Section 5.7 but only for and to the extent attributable to any
taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date; provided, however, that Aon shall not be liable for
or pay, and shall not indemnify or hold harmless any Buyer Group Member from and against (I) any Taxes shown as a liability or reserve on the Net Worth Adjustment Report and taken into account in the calculation of the Closing Date Net Worth
(“Reserved Taxes”); (II) any Taxes (other than any Section 338 Taxes) that result from any actual or deemed election under Section 338 of the Code or any similar provisions of state, local or foreign law as a result of the
purchase of the Shares or the deemed purchase of shares of any of the Subsidiaries or that result from Buyer, any Affiliate of Buyer, the Company or any Subsidiary engaging in any activity or transaction that would cause the transactions
contemplated by this Agreement to be treated as a purchase or sale of assets of the Company or any Subsidiary for federal, state or local Tax purposes and (III) any Taxes imposed on the Company or any Subsidiary or for which the Company or any
Subsidiary may otherwise be liable as a result of transactions occurring on the Closing Date that are properly allocable (based on, among other relevant factors, factors set forth in Treasury Regulation § 1.1502-76(b)(1)(ii)(B)) to the portion
of the Closing Date after the Closing and would not have been otherwise included as part of the Section 338 Taxes (the Taxes described in this proviso being referred to as “Excluded Taxes”); provided, further,
that Aon’s liability for any withholding or employment Taxes relating to any taxable year or period ending on or before the Closing Date or the portion of any Straddle Period ending on and including the Closing Date shall be governed solely by
the provisions of Section 5.7 (determined without regard to the last sentence thereof), including the applicable limitations of Article XI, and shall not be governed by this Section 8.1. Except as otherwise provided in
this Section 8.1, Aon shall be entitled to any refund of (or credit for) Taxes allocable to any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period
ending on and including the Closing Date. For the avoidance of doubt, no provision in this Agreement shall be read to require Buyer to pay over any amount of Taxes to Aon that has been reflected as a receivable (or netted against a Tax liability) in
the Net Worth Adjustment Report or to require Buyer to indemnify Aon for any Taxes that would be treated as Section 338 Taxes as well as being treated under another provision of this Section 8.1. 
 (ii) Buyer shall be liable for and pay, and pursuant to Article XI (and subject to the provisions thereof but not subject to the limitations in
Section 11.2((a)) shall indemnify and hold harmless each Seller Group Member from and against, (A) any and all Taxes imposed on the Company or any Subsidiary or for which the Company or any Subsidiary may otherwise be liable for any
taxable year or period that begins after the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period beginning after the Closing Date and (B) Excluded Taxes. Except as otherwise provided herein, Buyer shall be
entitled to any refund of (or credit for) Taxes described in clauses (A) and (B). Buyer shall pay Aon (in the case of any Reserved Taxes that are required to be paid by Aon on behalf of the consolidated group of corporations, combined group of

authority (in the case of all other Reserved Taxes) all Reserved Taxes in accordance with past practice (but, in the case of Reserved Consolidated Taxes, in no event later than five (5) business days following the Net Worth Adjustment Report
Finalization Date). For the avoidance of doubt, Buyer shall pay Aon the full amount accrued for Reserved Consolidated Taxes (regardless of any actual Tax liability). 
  

 40 

 (iii) For purposes of Sections 8.1(a)(i) and 8.1(a)(ii), whenever it is necessary to
determine the liability for Taxes of the Company or a Subsidiary for a Straddle Period, the determination of such Taxes for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the
Closing Date shall be determined by assuming that the Straddle Period consisted of two taxable years or periods, one which ended at the close of the Closing Date and the other which began at the beginning of the day following the Closing Date, and
items of income, gain, deduction, loss or credit of the Company for the Straddle Period shall be allocated between such two taxable years or periods on a “closing of the books basis” by assuming that the books of the Company or such
Subsidiary were closed at the close of the Closing Date; provided, however, that (I) transactions occurring on the Closing Date that are properly allocable (based on, among other relevant factors, factors set forth in Treasury
Regulation Section 1.1502-76(b)(1)(ii)(B)) to the portion of the Closing Date after the Closing shall be allocated to the taxable year or period that is deemed to begin at the beginning of the day following the Closing Date and (II) exemptions,
allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation, shall be apportioned between such two taxable years or periods on a daily basis. 
 (iv) If, as a result of any action, suit, investigation, audit, claim, assessment or amended Tax Return, there is any change after the Closing Date in
an item of income, gain, loss, deduction, credit or amount of Tax that results in an increase in a Tax liability for which Aon would otherwise be liable pursuant to Section 8.1(a)(i), and such change is reasonably expected to result in a
decrease in the Tax liability of the Company, any Subsidiary, Buyer or any Affiliate or successor thereof for any taxable year or period beginning after the Closing Date or for the portion of any Straddle Period beginning after the Closing Date, Aon
shall not be liable under Section 8.1(a)(i) with respect to such increase to the extent of the present value (using a discount rate equal to the then “Federal Mid-Term Rate,” as that term is defined in Section 1274(d) of
the Code) of such decrease (and, to the extent such increase in Tax liability is paid to a taxing authority by Aon or any Affiliate thereof, Buyer shall pay Aon an amount equal to the present value of such decrease). 
 (v) Notwithstanding anything herein to the contrary, Aon and Buyer shall be equally responsible for and shall each pay 50% of all real property transfer
or gains Tax, sales Tax, use Tax, stamp Tax, stock transfer Tax, or other similar Tax imposed on the transactions contemplated by this Agreement (except the restructuring described in Section 8.8, which Taxes, if any, shall be the
responsibility of Aon). 
 (b) Tax Returns. (i) Aon shall timely file or cause to be timely filed when due (taking into account
all extensions properly obtained) all Tax Returns required to be filed with respect to the Company and the Subsidiaries for taxable years or periods ending on or prior to the Closing Date, and Aon shall remit, or cause to be remitted, any Taxes due
in respect of such Tax Returns, and Buyer shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) all other Tax Returns that are required to be filed by or with respect to the Company and the
Subsidiaries, and Buyer shall remit, or cause to be remitted, any Taxes due in respect of such Tax Returns. With respect to Tax Returns to be filed by Buyer 

  

 41 

 
pursuant to the preceding sentence that relate to any Straddle Period (I) such Tax Returns shall be filed in a manner consistent with past practice and
no position shall be taken, election made or method adopted that is inconsistent with positions taken, elections made or methods used in prior periods in filing such Tax Returns (including any such position, election or method which would have the
effect of accelerating income to periods for which Aon is liable or deferring deductions to periods for which Buyer is liable) and (II) such Tax Returns shall be submitted to Aon not later than 30 days prior to the due date for filing such Tax
Returns (or, if such due date is within 45 days following the Closing Date, as promptly as practicable following the Closing Date) for review and approval by Aon, which approval may not be unreasonably withheld. Aon or Buyer shall pay the other
party for the Taxes for which Aon or Buyer, respectively, is liable pursuant to Section 8.1(a) but which are payable with any Tax Return to be filed by the other party pursuant to this Section 8.1(b) upon the written request
of the party entitled to payment, setting forth in detail the computation of the amount owed by Aon or Buyer, as the case may be, but in no event earlier than 10 business days prior to the due date for paying such Taxes, without regard to the
aggregate indemnification limitations set forth in Sections 11.1(a) and 11.2(a). 
 (ii) None of Buyer or any Affiliate of
Buyer shall (or shall cause or permit the Company or any Subsidiary to) amend, refile or otherwise modify (or grant an extension of any statute of limitation with respect to) any Tax Return relating in whole or in part to the Company or any
Subsidiary with respect to any taxable year or period ending on or before the Closing Date (or with respect to any Straddle Period) without the prior written consent of Aon, which consent may not be unreasonably withheld. 
 (iii) Buyer shall promptly cause the Company and each Subsidiary to prepare and provide to Aon a package of Tax information materials, including
schedules and work papers (the “Tax Package”), required by Aon to enable Aon to prepare and file all Tax Returns required to be prepared and filed by it pursuant to Section 8.1(b)(i). The Tax Package shall be completed
in accordance with past practice, including past practice as to providing such information and as to the method of computation of separate taxable income or other relevant measure of income of the Company and the Subsidiaries. Buyer shall cause the
Tax Package to be delivered to Aon within 75 days after the Closing Date. 
 (c) Contest Provisions. After the Closing Date, in the
case of any audit, examination, claim or other proceeding (“Proceeding”) with respect to Taxes for which Aon is or may be liable or entitled to a refund pursuant to this Agreement, Buyer shall promptly inform Aon of such Proceeding,
and shall afford Aon, at Aon’s expense, the opportunity to control the conduct of such Proceedings and initiate any claim for refund, file any amended return or take any other action which Aon deems appropriate with respect to such Taxes;
provided, however, that if Aon chooses to control such Proceeding and such Proceeding is reasonably expected to affect Taxes for which Buyer is liable, Buyer shall be entitled to participate at its expense. Buyer shall execute or cause
to be executed powers of attorney or other documents necessary to enable Aon to take all actions desired by Aon with respect to such Proceeding to the extent such Proceeding may affect the amount of taxes for which Aon is liable or entitled to a
refund pursuant to this Agreement. Any Proceeding with respect to Taxes for a period which includes but does not end on the Closing Date shall be controlled by Buyer, but Aon shall be entitled to participate at its expense. Notwithstanding any
provision of this Section 8.1 to the contrary, Aon shall not settle any Proceeding, initiate any claim for refund or file any amended Tax Return 

  

 42 

 
without the prior written consent of Buyer, which consent shall not be unreasonably withheld, if, as result of such Proceeding, claim for refund or amended
Tax Return, the Taxes payable by Buyer or the Company for a taxable period for which Aon is not obligated to indemnify Buyer or the company pursuant to this Section 8.1 would likely be increased. Notwithstanding any provision of this
Section 8.1 to the contrary, Buyer shall not settle any Proceeding, initiate any claim for refund or file any amended return without the prior written consent of Aon, which consent shall not be unreasonably withheld if, as a result of
such Proceeding, claim for refund or amended Tax Return, the Taxes for which Aon is obligated to indemnify Buyer or the company pursuant to this Section 8.1 would likely be increased. 
 (d) Assistance and Cooperation. After the Closing Date, Aon and Buyer shall (and shall cause their respective Affiliates to): 
 (i) assist the other parties in preparing any Tax Returns which such other party is responsible for preparing and filing in accordance with
Section 8.1(b); 
 (ii) cooperate fully in preparing for any audits of, or disputes with taxing authorities regarding, any Tax
Returns of the Company and the Subsidiaries; 
 (iii) make available to the others and to any taxing authority as reasonably requested all
information, records, and documents relating to Taxes of the Company and the Subsidiaries; 
 (iv) provide timely notice to the others in
writing of any pending or threatened Tax audits or assessments of the Company and the Subsidiaries for taxable periods for which the other may have a liability under this Section 8.1; 
 (v) furnish the others with copies of all correspondence received from any taxing authority in connection with any Tax audit or information request with
respect to any such taxable period; 
 (vi) timely sign and deliver such certificates or forms as may be necessary or appropriate to
establish an exemption from (or otherwise reduce), or file Tax Returns or other reports with respect to, Taxes described in Section 8.1(a)(v) (relating to sales, transfer and similar Taxes); and 
 (vii) timely provide to the others powers of attorney or similar authorizations necessary to carry out the purposes of this Section 8.1.

 (e) Election Under Section 338(h)(10). (i) Each of Aon and Buyer shall cause an authorized person to make a joint
election under Section 338(h)(10) of the Code and a similar election under any applicable state, local or foreign income tax law for each domestic Company and Subsidiary treated as a corporation for U.S. federal income tax purposes
(collectively, the “Section 338(h)(10) Elections”). To facilitate such election, Aon shall deliver to Buyer on the Closing Date an Internal Revenue Service Form 8023 and, within 60 days after the Closing Date (but in no event after
the date which is 60 days prior to the due date) Aon shall deliver any similar form under applicable state, local or foreign income tax law (collectively, the “Forms”) with respect to the Section 338(h)(10) Elections, which
Forms shall have been duly 

  

 43 

 
executed by an authorized person. Aon and Buyer shall cooperate in the preparation of any information to be included in the Forms or attachments thereto.
Buyer shall (1) cause the Forms to be duly executed by an authorized person for Buyer, (2) subject to the following paragraph, prepare and attach any schedules required to be attached, and (3) provide a copy of the executed Forms and
schedules to Aon within 120 days after the Closing Date or such later date reasonably agreed by Aon and Buyer. Within 150 days after the Closing Date or such later date reasonably agreed to by Aon and Buyer in writing (but in no event after the date
that is 60 days prior to the due date), Aon shall review and provide any comments on the Forms to Buyer. Buyer shall consider any such comments received from Aon and shall make any agreed changes to the Forms prior to filing the Forms with the
relevant taxing authorities. Buyer shall duly and timely file the Forms as prescribed by Treasury Regulation §1.338(h)(10)-1 or the corresponding provisions of applicable state, local or foreign income tax Law, and deliver evidence of such
filings to Aon. If any changes are required in these forms as a result of information which is first available after these forms are prepared, the parties will promptly agree on such changes. 
 (ii) Within 60 days following the final determination of the Net Worth Adjustment Amount pursuant to Section 4.5, Buyer shall prepare and
deliver to Aon a schedule (the “Allocation Schedule”) allocating the Aggregate Deemed Sales Price, as defined in Treasury Regulation Section 1.338-4, for the assets of the Company and each Subsidiary for which a
Section 338(h)(10) Election will be made, among the assets of the Company and each such Subsidiary. The Allocation Schedule shall be reasonable and shall be prepared in accordance with Section 338(h)(10) of the Code and the Treasury
Regulations thereunder. Aon agrees to review such Allocation Schedule and provide written notice to Buyer of any disputes within 30 days after the date on which the Allocation Schedule is delivered to Aon. The Allocation Schedule shall be deemed to
be accepted by and shall be conclusive and binding on Aon and Buyer in the event Aon does not timely provide written notice to Buyer. If a change proposed by Aon is disputed by Buyer, then Aon and Buyer shall negotiate in good faith to resolve such
dispute. If, after a period of 20 days following the date on which Aon gives Buyer notice of any such proposed change, any such proposed change still remains disputed, then Buyer and Aon shall together choose an Accounting Firm to resolve any
remaining disputes. The Accounting Firm shall act as an arbitrator to determine, based solely on presentations by Buyer and Aon, and not by independent review, only those issues still in dispute with respect to the Allocation Schedule. The decision
of the Accounting Firm shall be final and binding. All of the fees and expenses of the Accounting Firm shall be equally paid by Buyer, on the one hand, and Aon, on the other hand. Buyer and Aon each agrees that promptly upon receiving the final and
binding Allocation Schedule it shall return an executed copy thereof to the other party. Each of Buyer and Aon agrees to file all federal, state, local and foreign Tax Returns in accordance with the Allocation Schedule. 
 (f) Elections under Section 338 for International Subsidiaries. Aon and Buyer agree to work together to determine whether Buyer shall be
entitled to make an election under Section 338 of the Code or under any applicable similar provision of state or foreign law with respect to any of the Subsidiaries that is not a domestic corporation for U.S. Federal income tax purposes and
that Buyer may choose to make the election without agreement of Aon if Buyer agrees to pay any incremental Taxes on Aon resulting from such election. 
  

 44 

 (g) Options; Restricted Stock. 
 (i) Options. In the event that subsequent to the Closing Date any current or former employee of the Company or a Subsidiary exercises options to
purchase stock of Aon which options were received by such employee in connection with the performance of services for the Company, such Subsidiary or an Affiliate of the Company or such Subsidiary, as the case may be, and are outstanding on the
Closing Date (the “Aon Options”), Aon and Buyer agree and acknowledge that they shall report the exercise of the Aon Options in accordance with clause (iii) below. Buyer shall (or shall cause its Affiliates to) immediately
inform Aon of any event that results in the forfeiture of any Aon Options by any person holding such options. 
 (ii) Stock-Based
Awards. In the event that subsequent to the Closing Date any current or former employee of the Company or a Subsidiary becomes vested (in whole or in part) in any restricted stock units or performance share units of Aon which (A) were
received by such employee in connection with the performance of services for the Company, such Subsidiary or an Affiliate of the Company or such Subsidiary, as the case may be, and (B) with respect to which an effective election under
Section 83(b) of the Code was not made (the “Aon Stock-Based Awards”), Aon and Buyer agree and acknowledge that they shall report the vesting of the Aon Stock-Based Awards in accordance with clause (iii) below. 

(iii) Compensation Expense; Employment Taxes; Reimbursement. Upon the exercise of the Aon Options or the vesting of the Aon Stock-Based
Awards, as applicable, the Company or a Subsidiary, as applicable, shall, if and only if Aon has determined that Aon cannot claim the deduction, (A) claim the compensation expense deduction associated with such exercise or vesting measured by
the fair market value of Aon stock at the time of such exercise (less the exercise price) or vesting (the “Compensation Deduction”), (B) pay all employment and withholding Taxes resulting from such exercise or vesting and
(C) file all Tax Returns related to the payment of such employment and withholding Taxes. The Company or such Subsidiary shall pay Aon an amount equal to the tax benefit realized by Buyer or any of its Affiliates (determined on an After-Tax
Basis) as a result of such Compensation Deduction less the after-tax cost to Buyer of any employment Taxes required to be paid on the exercise or vesting of the Aon Option or Aon Stock-Based Awards within 60 days of the date the Tax benefits are
realized by the Company or such Subsidiary from the Compensation Deduction. 
 (h) Buyer shall not cause or permit the Company or
Subsidiaries to carry back any loss, credit or other allowance to a Tax period (or any portion thereof) ending on or prior to the Closing Date without Aon’s prior written consent (which consent may not be unreasonably withheld). In the event
that Buyer, the Company or a Subsidiary is required to carry back any amount to a Tax period ending on or prior to the Closing Date, Aon will pay to Buyer the amount of any refund (or reduction in Taxes) obtained by Aon as a result of such carry
back. 
 (i) All amounts paid as an indemnity by one party to the other under this Agreement will be treated, to the extent permitted under
applicable law, as adjustments to the Purchase Price for all Tax purposes. 
 Section 8.2 Employee Matters.
(a) Continued Employment. As of the Closing Date, Buyer agrees to, or to cause an Affiliate of Buyer to, continue to employ as a successor employer all of the employees of the Company and the Subsidiaries (including all such employees
who have rights of employment in accordance with the established practices or 

  

 45 

 
policies of the Company and the Subsidiaries on return from any vacation, leave or other authorized absence) (collectively, the “Transferred
Employees”). For a period of at least one year following the Closing Date, each Transferred Employee shall be entitled to receive while in the employment of Buyer or its Affiliates at least the same salary or hourly wages as were provided
to such employee by the Company and the Subsidiaries, immediately prior to the Closing Date. For the period from the Closing Date through the last day of the calendar year in which the Closing Date occurs, the Buyer shall, or shall cause an
Affiliate of Buyer to, continue to maintain for the benefit of the Transferred Employees while in the employment of Buyer or its Affiliates the bonus program in which such Transferred Employees participated as employees of the Company or a
Subsidiary immediately prior to the Closing Date. Notwithstanding any provision herein to the contrary, neither Buyer nor any of its Affiliates (including the Company and the Subsidiaries) shall be obligated to continue to employ any Transferred
Employee for any specific period of time following the Closing Date, subject to applicable law. 
 (b) Buyer Benefit Plans. Through
the end of the calendar year during which the Closing Date occurs, Buyer shall provide, or shall cause the Company and the Subsidiaries to provide, employee benefits (including, for the avoidance of doubt, retirement, welfare and fringe benefits) to
Transferred Employees that provide at least substantially comparable aggregate value to those benefits provided under the Company Plans in effect immediately prior to the Closing Date. 
 (c) Company Plans and International Plans. (i) Except as set forth in Schedule 8.2(c), as provided for in the Closing Date Net Worth
or as otherwise specifically provided in this Section 8.2 (collectively, the “Assumed Plan Liabilities”), neither Buyer nor any of its Affiliates shall assume any obligations under or liabilities with respect to, and it
shall not receive any right or interest in the assets of, any Company Plans. Buyer shall assume (or cause the Company and the Subsidiaries to assume) the Assumed Plan Liabilities. Effective as of the Closing Date, except as otherwise specifically
provided in this Agreement, all Transferred Employees will cease any participation in, and any benefit accrual under, all Company Plans; provided, however, that if Buyer does not sponsor a retiree medical plan for pre-age 65 or
post-age 65 retirees, then otherwise eligible Transferred Employees may apply for coverage on or before December 31, 2008 under Aon’s U.S. retiree medical plan and will be granted age and service credit for their employment with the Buyer
or its Affiliates for eligibility purposes. Buyer will have no responsibility in connection with the administration or funding of any Aon-sponsored retiree medical plan. 
 (ii) As of the Closing Date, Buyer shall assume (or will cause the Company and the Subsidiaries to continue) the International Benefit Plans set forth in Schedule 8.2(c) (collectively, the “Assumed
International Plans”), including assuming or retaining, as applicable, all liabilities and obligations for benefits payable under the Assumed International Plans. Except for assets specifically relating to such Assumed International Plans,
no portion of the assets of any trust or other fund maintained by Aon for the purpose of paying benefits under the Assumed International Plans will be transferred to Buyer, the Company or the Subsidiaries. 
 (iii) Buyer currently maintains one or more qualified defined contribution plans (“Buyer’s DC Plans”) that contain or will contain
all provisions necessary for 

  

 46 

 
the acceptance of direct rollovers (in the form of cash and notes relating to plan participant loans) of “eligible rollover distributions” as
defined in the Code and applicable Requirements of Law that Transferred Employees are eligible to receive from Aon’s defined contribution plans (“Aon’s DC Plans”) without adversely affecting the qualified status of
Aon’s DC Plans; provided, however, that Buyer’s DC Plan will not be required to accept the rollover of any amount attributable to a form of contribution that is not otherwise available under Buyer’s DC Plan. Buyer’s
DC Plans will contain provisions to permit any such direct rollover to include the promissory note or notes representing any plan loans outstanding to the Transferred Employee under Aon’s DC Plans on the date of the direct rollover, and Buyer,
the Company and Aon will cooperate with each other to enable such direct rollovers to occur before such loans become defaulted. Aon agrees not to place any such loans in default for at least 90 days following the Closing Date. 
 (d) Layoff Benefits. Notwithstanding any of the foregoing to the contrary, following the Closing Date, Buyer agrees to, or to cause its Affiliates
to, provide severance benefits to any Transferred Employee who is laid off during the one-year period beginning on the Closing Date in an amount that is at least equal to the layoff benefits that would have been paid to such employee pursuant to the
terms of the Company Plans as in effect immediately prior to the Closing Date, to be calculated, however, on the basis of the employee’s base salary and service at the time of the layoff; provided, however, that if an individual
is entitled to a severance or layoff benefit under a Company Employment Agreement, the individual will not be entitled to a layoff benefit under this paragraph (d). 
 (e) Individual Employment Contracts. Except as set forth on Schedule 8.2(e), effective as of the Closing Date, Buyer shall assume, or cause an Affiliate to continue to be obligated under or assume the
Company’s and the Subsidiaries’ obligations under all individual employment, termination, retention, severance or other similar contracts or agreements with any current or former employee of the Company and the Subsidiaries and all of the
obligations as the employer under such contracts and agreements, as set forth in Schedule 5.18. 
 (f) Welfare Benefits. Except
as otherwise expressly provided herein, Aon or one of its Affiliates shall retain responsibility under the Company Plans that are Welfare Plans in which the Transferred Employees participate with respect to all amounts that are payable by reason of,
or in connection with, any and all welfare benefit claims made by the Transferred Employees and their eligible dependents but only to the extent the claims were incurred prior to the Closing Date. However, Buyer shall reimburse Aon or one of its
Affiliates promptly for any payments of welfare benefits, properly made by Aon or one of its Affiliates in accordance with the terms of the applicable welfare plan maintained by Buyer or one of its Affiliates, to eligible Transferred Employees and
their eligible dependents on or after the Closing Date with respect to claims incurred after the Closing Date upon receipt of periodic billings for such amounts. Buyer and its Affiliates shall be responsible for all other welfare benefit claims made
by the Transferred Employees and their eligible dependents to the extent such claims were incurred on or after the Closing Date. 
 (g)
Credit for Service. To the extent that service is relevant for purposes of eligibility and vesting (but not for purposes of defined benefit pension benefit accruals) under any retirement plan, employee benefit plan, program or arrangement
established or maintained 

  

 47 

 
by Buyer or any of its Affiliates for the benefit of the Transferred Employees, following the Closing Date such plan, program or arrangement shall credit
such Transferred Employees for service earned on and prior to the Closing Date with the Company, the Subsidiaries, any of their respective Affiliates or any of their respective predecessors (but only to the extent Aon credited such service) in
addition to service earned with Buyer or any of Buyer’s Affiliates after the Closing Date. 
 (h) Preexisting Conditions;
Coordination. Following the Closing Date, Buyer shall, or shall cause its Affiliates to, waive limitations on eligibility, enrollment and benefits relating to any preexisting medical conditions of the Transferred Employees and their eligible
dependents to the same extent as any other new employee of Buyer. Following the Closing Date, Buyer shall recognize, or shall cause its Affiliates to also recognize, for purposes of annual deductible and out of pocket limits under its health and
dental plans (the “Buyer Plans”), deductible and out of pocket expenses paid by Transferred Employees and their respective dependents under health and dental Company Plans in the calendar year in which the Closing Date occurs to the
extent the Transferred Employees participate in any such Buyer Plans in such same calendar year. 
 (i) Vacations. Buyer shall, or
shall cause its Affiliates to, continue a vacation program for the benefit of the Transferred Employees through at least the end of the calendar year in which the Closing occurs that is at least as favorable as the vacation program of the Company
and the Subsidiaries in effect immediately prior to the Closing Date. Buyer shall, or shall cause its Affiliates to, recognize and provide all accrued but unused vacation of each Transferred Employee as of the Closing Date. Neither Aon nor its
Affiliates shall have any obligation or liability to pay or provide any vacation payments claimed on or after the Closing Date. 
 (j)
Bonuses. Buyer shall, or shall cause its Affiliates to, assume the bonus programs for Transferred Employees in existence as of the Closing Date and shall pay to the Transferred Employees the bonuses they earn under such programs with respect
to the bonus determination period that includes the Closing Date, it being understood that bonus amounts shall be fully accrued with respect to all periods through the Closing Date (and including the Closing) in the calculation of Closing Date Net
Worth. 
 (k) Healthcare Flexible Spending Account Program. Buyer shall, or shall cause its Affiliates to, establish or maintain a
Healthcare Flexible Spending Account program for each Transferred Employee who, in the portion of the calendar year on or prior to the Closing Date, contributed to the Healthcare Flexible Spending Account program of Aon. The beginning balance as of
the Closing Date in Buyer’s Healthcare Flexible Spending Account program shall be the unused portion of the balance in Aon’s Healthcare Flexible Spending Account program, and Aon shall transfer to Buyer an amount, in cash, equal to such
balance. 
 (l) COBRA. Following the Closing Date, Buyer shall, or shall cause an Affiliate to, provide continuation health care
coverage to all Transferred Employees and their qualified beneficiaries, regardless of when a “qualifying event” occurs, in accordance with the continuation health care coverage requirements of Section 4980B of the Code and Title I,
Subtitle B, Part 6 of ERISA (“COBRA”) with respect to claims incurred at any time on or after the Closing Date. Aon or one of its Affiliates shall provide COBRA coverage for former employees of the Company and the Subsidiaries who
do not become Transferred Employees. 
  

 48 

 (m) WARN. Buyer shall be responsible for all liabilities or obligations under the Worker
Adjustment and Retraining Notification Act and similar state and local rules, statutes and ordinances resulting from the Closing or from Buyer’s, the Company’s or a Subsidiary’s actions following the Closing. 
 (n) Workers’ Compensation Liabilities. As of the Closing Date, Buyer will cause the Company and the Subsidiaries to assume (or reimburse Aon
for) all liabilities and obligations relating to compensation and benefits under any state workers’ compensation or similar law payable following the Closing Date to or with respect to any employee or former employee of the Company or any of
the Subsidiaries who was employed by the Company or the Subsidiaries on the date the claim arose or the incident on which the claim is based occurred. 
 Section 8.3 Securities Law Legends. Buyer agrees and understands that the Shares have not been, and will not be, registered under the Securities Act or the securities laws of any state or other
Administrative Authority and that the Shares may be sold or disposed of only in one or more transactions (i) registered under the Securities Act, applicable state securities laws and/or the laws of any other applicable Administrative Authority
or (ii) as to which an exemption from the registration requirements of the Securities Act, applicable state securities laws and/or the laws of any other applicable Administrative Authority is available. Buyer acknowledges and agrees that no
person has any right to require Aon or the Company to cause the registration of any of the Shares. The certificates representing the Shares shall contain a legend similar to the following and other legends necessary or appropriate under applicable
state securities laws or the laws of any other Administrative Authority: 
 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS A REGISTRATION STATEMENT UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS WITH
RESPECT TO SUCH SHARES IS EFFECTIVE OR UNLESS THE COMPANY IS IN RECEIPT OF AN OPINION OF COUNSEL SATISFACTORY TO IT TO THE EFFECT THAT SUCH SHARES MAY BE SOLD WITHOUT REGISTRATION UNDER THE ACT AND SUCH LAWS. 
 Section 8.4 Insurance; Risk of Loss. Aon will cause the Company and the Subsidiaries to keep insurance policies currently maintained
by the Company or the Subsidiaries covering their business, assets and current or former employees, as the case may be, or suitable replacements therefor, in full force and effect through the close of business on the Closing Date. From and after the
Closing Date, Buyer shall be solely responsible for all insurance coverage and related risk of loss based on claims pending as of the Closing Date and claims made after the Closing Date, without regard to when the event giving rise to any such claim
occurred, with respect to the Company, the Subsidiaries and their business, assets and current or former employees. To the extent that after the Closing any party hereto requires any information 

  

 49 

 
regarding claim data, payroll or other information in order to make filing with insurance carriers or self insurance regulators from another party hereto,
such other party will promptly supply such information. 
 Section 8.5 Release of Guaranties. Buyer shall use all
reasonable efforts to cause Aon and its Affiliates to be fully released, as of the Closing Date or as promptly as practicable after the Closing Date, in respect of all obligations under any guaranties, letters of credit, letters of comfort, bid
bonds or performance or surety bonds or cash or other collateral obtained or given by Aon or its Affiliates relating to any parcel of Leased Real Property or any other contractual commitment of the Company and the Subsidiaries (collectively, the
“Guaranties”). If Buyer is unable to effect such a substitution and release with respect to any Guaranty, Buyer shall indemnify each Seller Group Member against any and all Loss or Expense arising from such Guaranty. Without
limiting the foregoing, after the Closing Date, Buyer will not, and will not permit any of its Affiliates to, renew, extend, amend or supplement any contract, lease or other obligation that is covered by a Guaranty without providing Aon with
evidence reasonably satisfactory to them that the Guaranty has been released. Any cash or other collateral posted by Aon or its Affiliates in respect of any Guaranty shall be delivered to Aon. 
 Section 8.6 Noncompetition and Nonsolicitation. (a) For a period of two years following the Closing, Aon shall not, and shall
cause its Affiliates not to, solicit any employees of Buyer or any of its Affiliates identified to Aon as part of the transactions contemplated by this Agreement to leave the employ of Buyer or its Affiliates or violate the terms of their contracts,
or any employment arrangements, with the Company or any Subsidiary; provided, however, that Aon or any of its Affiliates may solicit any Transferred Employees who are discharged by the Company or a Subsidiary, and, provided,
further, that nothing in this Section 8.6(a) shall prohibit Aon or any of its Affiliates from employing any Transferred Employee who (i) initiates discussions regarding such employment without any direct or indirect
solicitation, (ii) seeks employment in response to any general advertisement or other similar method and not in response to any direct or indirect solicitation efforts or (iii) whose employment has been terminated prior to commencement of
employment discussions. 
 (b) For a period of two years following the Closing, Buyer shall not, and shall cause its Affiliates (including
the Company and the Subsidiaries) not to solicit any employees of Aon or its Affiliates identified to Buyer as part of the transactions contemplated by this Agreement to leave the employ of Aon or its Affiliates, as applicable, or violate the terms
of their contracts, or any employment arrangements, with Aon or its Affiliates, as applicable; provided, however, that Buyer or any of its Affiliates may solicit any such employees who are discharged by Aon or its Affiliates, as
applicable; provided, further, that nothing in this Section 8.6(b) shall prohibit Buyer or any of its Affiliates from employing any such employee who (i) initiates discussions regarding such employment without any
direct or indirect solicitation, (ii) seeks employment in response to any general advertisement or other similar method and not in response to any direct or indirect solicitation efforts or (iii) whose employment has been terminated prior
to commencement of employment discussions. 
 (c) As a separate and independent covenant, for a period of two (2) years following the
Closing, Aon shall not, and shall cause its Affiliates not to, engage in a Restricted Business anywhere in the world; provided, however, that, for the purposes of this Section 8.6, (x)

  

 50 

 
ownership of securities having no more than five percent of the outstanding voting power of any Person whose capital stock or equity is listed on any
national or international securities exchange or quotation system and (y) ownership of not more than 25% of any private equity fund or alternative investment vehicle in which Aon or its Affiliates is a passive investor shall not be deemed to be
a violation of this Section 8.6. 
 (d) Notwithstanding the provisions of this Section 8.6 and without implicitly
agreeing that the following activities would be subject to the provisions of Section 8.6(c), nothing in this Agreement or in the Seller Ancillary Agreements shall preclude, prohibit or restrict Aon or any of its Affiliates from:
(i) engaging in or owning an interest in any entity that engages in any Exempt Business Activities; (ii) acquiring, and following such acquisition, actively engaging in any business that has a subsidiary, division, group, franchise or
segment that is engaged in any Restricted Business (an “Acquired Business”), so long as for the most recent fiscal year ending prior to the date of such purchase, the gross written premiums or revenues of such business derived from
a Restricted Business were less than 33-1/3% of the total consolidated gross written premiums or revenues of such business; or (iii) engaging in a Change of Control or, if the acquiring Person has a subsidiary, division, group, franchise or
segment that is engaged in a Restricted Business at the time of the Change of Control, thereafter engaging in the Restricted Business. Nothing in this Section 8.6 shall require Aon or any of its Affiliates to divest or dispose of all or
any portion of an Acquired Business to the extent engaging in Exempt Business Activities. 
 Section 8.7 Use of Names.
(a) Aon is not conveying ownership rights or granting Buyer or its Affiliates (including the Company and the Subsidiaries after the Closing) a license to use any of the tradenames, service marks or trademarks of Aon or any Affiliate of Aon
(other than the trademarks and service marks included in the Intellectual Property identified in Schedule 5.11(a)) (collectively, the “Retained Names and Marks”) and, after the Closing, Buyer and its Affiliates (including the

Section 8.7.

in no event later than 120 days after the Closing Date, using (i) any advertising or promotional materials and (ii) any stationery, business cards, business forms and other similar items, in each case that contain anywhere thereon any of
the Retained Names and Marks; provided, however, that Buyer shall (and shall cause the Company and the Subsidiaries to), when using items referred to in clause (ii) in the context of entering into or conducting contractual
relationships, make reasonably clear to all other applicable parties that Buyer and the Company and the Subsidiaries, rather than Aon or any Affiliate of Aon is the party entering into or conducting the contractual relationship; provided,
further, that Buyer shall (and shall cause the Company to) ensure that personnel of the Company and the Subsidiaries using such items shall not, and shall have no authority to, hold themselves out as officers, employees or agents of Aon or
any Affiliate of Aon; provided, further, that Buyer shall not be obligated to pay Aon for the use of the Retained Names and Marks as contemplated by this Section 8.7. With respect to all materials used after the Closing

the calculation of the Closing Date Net Worth.

 56 

 Section 11.3 Notice of Claims. Any Buyer Group Member or Seller Group Member seeking
indemnification hereunder (the “Indemnified Party”) shall give promptly to the party obligated to provide indemnification to such Indemnified Party (the “Indemnitor”) a notice (a “Claim Notice”)
describing in reasonable detail the facts giving rise to the claim for indemnification hereunder and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim, and a reference to the
provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based; provided, however, that a Claim Notice in respect of any action at law or suit in
equity by or against a third Person as to which indemnification will be sought shall be given promptly after the action or suit is commenced. 
 Section 11.4 Determination of Amount. (a) In calculating any Loss or Expense, such amounts shall be calculated on an After-Tax Basis and shall be net of any third-party insurance, indemnification or other proceeds
which have been recovered by the Indemnified Party under any insurance policy or other contract, agreement or undertaking in connection with the facts giving rise to the right of indemnification. The Indemnified Party shall use commercially
reasonable efforts to recover third-party insurance, indemnification or other proceeds that may be recoverable. 
 (b) After the giving of
any Claim Notice pursuant to Section 11.3, the amount of indemnification to which an Indemnified Party shall be entitled under this Article XI shall be determined: (i) by the written agreement between the Indemnified Party
and the Indemnitor; (ii) by a final judgment or decree of any court of competent jurisdiction; or (iii) by any other means to which the Indemnified Party and the Indemnitor shall agree. The judgment or decree of a court shall be deemed
final when the time for appeal, if any, shall have expired and no appeal shall have been taken or when all appeals taken shall have been finally determined. The Indemnified Party shall have the burden of proof in establishing the amount of Losses
and Expenses suffered by it. 
 Section 11.5 Third Person Claims. (a) Any party seeking indemnification provided for
under this Agreement in respect of, arising out of or involving a claim or demand made by any third Person against the Indemnified Party shall notify the Indemnitor in writing, and in reasonable detail, of the third Person claim within 10 days after
receipt by such Indemnified Party of written notice of the third Person claim. Thereafter, the Indemnified Party shall deliver to the Indemnitor, within five (5) business days after the Indemnified Party’s receipt thereof, copies of all
notices and documents (including court papers) received by the Indemnitor relating to the third Person claim. Notwithstanding the foregoing, should a party be physically served with a complaint with regard to a third Person claim, the Indemnified
Party shall notify the Indemnitor with a copy of the complaint within five (5) business days after receipt thereof and shall deliver to the Indemnitor within seven (7) business days after the receipt of such complaint copies of notices and
documents (including court papers) received by the Indemnified Party relating to the third Person claim. The failure to give notice as provided in this Section 11.5 shall not relieve the Indemnitor of its obligations hereunder except to
the extent it shall have been prejudiced by such failure. 
 (b) If any legal proceeding shall be threatened or instituted or any claim or
demand shall be asserted by any Person in respect of which payment may be sought by one party 

  

 57 

 
hereto from the other party under the provisions of this Article XI, the Indemnified Party shall promptly cause written notice of the assertion of any
such claim of which it has knowledge which is covered by this indemnity to be forwarded to the Indemnitor. Any notice of a claim by reason of any of the representations, warranties or covenants contained in this Agreement shall refer to the
provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based and describe in reasonable detail, the facts giving rise to an alleged basis for the claim and the
amount of the liability asserted against the Indemnitor by reason of the claim. In the event of the initiation of any legal proceeding against the Indemnified Party by a third Person, the Indemnitor shall have the sole and absolute right after the
receipt of notice, at its option and at its own expense, to be represented by counsel of its choice and to control, defend against, negotiate, settle or otherwise deal with any proceeding, claim, or demand which relates to any loss, liability or
damage indemnified against hereunder; provided, however, that the Indemnified Party may participate in any such proceeding with counsel of its choice and at its expense. Each of the parties hereto agrees to cooperate fully with the
other party in connection with the defense, negotiation or settlement of any such legal proceeding, claim or demand and to make available to the other party all witnesses, pertinent records, materials and information in such party’s possession
or under such party’s control relating thereto as is reasonably required by the other party. To the extent the Indemnitor elects not to defend such proceeding, claim or demand, and the Indemnified Party defends against or otherwise deals with
any such proceeding, claim or demand, the Indemnified Party may retain counsel, at the expense of the Indemnitor, and control the defense of such proceeding; provided, however, that the Indemnitor shall be obligated pursuant to this
Section 11.5 to pay for only one firm of counsel for all Indemnified Parties. Neither the Indemnitor nor the Indemnified Party may settle any such proceeding which settlement obligates the other party to pay money, to perform obligations
or to admit liability without the consent of the other party, such consent not to be unreasonably withheld. Furthermore, the Indemnitor may not, without the prior written consent of the Indemnified Party (such consent not to be unreasonably
withheld), settle any such proceeding or compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any Indemnified Party is or would reasonably be expected to be a party and indemnity
was or would reasonably be expected to be sought hereunder by such Indemnified Party, unless such settlement, compromise or consent (i) includes an unconditional release of such Indemnified Party from all liability on claims that are the
subject matter of such action, suit or proceedings and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any Indemnified Party. If the Indemnified Party shall refuse to consent to
the settlement of any third Person claim, so long as only money damages are involved and there is no admission of liability or wrongdoing with respect to the Indemnified Party, the liability of the Indemnitor in respect of such third Person claim
shall not exceed the amount for which the third Person claim could have been settled plus the amount of expenses incurred by the Indemnified Party prior to the time of and in connection with the proposed settlement to which it is entitled to
indemnification. After any final judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction and the time in which to appeal therefrom has expired, or a settlement shall have been
consummated, or the Indemnified Party and the Indemnitor shall arrive at a mutually binding agreement with respect to each separate matter alleged to be indemnified by the Indemnitor hereunder, the Indemnified Party shall forward to the Indemnitor
notice of any sums due and owing by it with respect to such matter and the Indemnitor shall pay all of the sums so owing to the Indemnified Party by wire transfer, certified or bank cashier’s check within 30 days after the date of such notice.

  

 58 

 (c) To the extent of any inconsistency between this Section 11.5 and
Section 8.1(c) (relating to Tax contests), the provisions of Section 8.1(c) shall control with respect to Tax contests. 
 Section 11.6 Limitations. (a) In any case where an Indemnified Party recovers from third Persons any amount in respect of a matter with respect to which an Indemnitor has indemnified it pursuant to this Article
XI, such Indemnified Party shall promptly pay over to the Indemnitor the amount so recovered (after deducting therefrom the full amount of the expenses incurred by it in procuring such recovery), but not in excess of the sum of (i) any
amount previously so paid by the Indemnitor to or on behalf of the Indemnified Party in respect of such matter and (ii) any amount expended by the Indemnitor in pursuing or defending any claim arising out of such matter. 
 (b) In no event shall any party be liable for any special, incidental, consequential (including loss of revenues or profits), exemplary or punitive
damages or diminution of value or any damages based on any type of multiple, whether arising under any legal or equitable theory or arising under or in connection with this Agreement, all of which are hereby excluded by agreement of the parties
regardless of whether or not any party to this Agreement has been advised of the possibility of such damages. 
 (c) Aon shall not be
required to indemnify and hold harmless any Buyer Group Member pursuant to Section 11.1(a) to the extent the matter in question was included in the computation of the Net Worth Adjustment Amount pursuant to Section 4.5.

 (d) Except for remedies that cannot be waived as a matter of law and injunctive and provisional relief (including specific performance),
if the Closing occurs, this Article XI shall be the exclusive remedy for breaches of this Agreement (including any covenant, obligation, representation or warranty contained in this Agreement or in any certificate delivered pursuant to this
Agreement) or otherwise in respect of the sale of the Shares contemplated hereby. Anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the
part of Aon or Buyer, after the consummation of the purchase and sale of the Shares contemplated by this Agreement, to rescind this Agreement or any of the transactions contemplated hereby. 
 Section 11.7 Mitigation. Each of the parties agrees to take all reasonable steps to mitigate their respective Losses and Expenses upon
and after becoming aware of any event or condition which could reasonably be expected to give rise to any Losses and Expenses that are indemnifiable hereunder. 
 ARTICLE XII 
 TERMINATION 
 Section 12.1 Termination. Anything contained in this Agreement to the contrary notwithstanding, this Agreement may be terminated at
any time prior to the Closing Date: 
 (a) by the mutual consent of Buyer and Aon; 
  

 59 

 (b) by Buyer if Aon shall have breached any of its representations, warranties, covenants or agreements
contained in this Agreement, which would give rise to the failure of a condition set forth in Article IX, which breach cannot be cured by the Termination Date as the same may be extended pursuant to Section 12.1(e) or which has
not been cured within 60 days of notice thereof by Buyer; 
 (c) by Aon if Buyer shall have breached any of its representations, warranties,
covenants or agreements contained in this Agreement which would give rise to the failure of a condition set forth in Article X which breach cannot be cured by the Termination Date as the same may be extended pursuant to
Section 12.1(e) or which has not been cured within 60 days of notice thereof by Aon; 
 (d) by Buyer or Aon if any court of
competent jurisdiction in the United States or other United States Administrative Authority shall have issued a final and non-appealable order, decree or ruling permanently restraining, enjoining or otherwise prohibiting the consummation of any
material transaction contemplated hereby; or 
 (e) by Buyer or Aon if the Closing shall not have occurred on or before July 31, 2008
(the “Termination Date”) (or such later date as may be agreed in writing to by Buyer and Aon); provided, however, that either Buyer or Aon may by written notice to the other delivered on or before July 31, 2008
extend the Termination Date until any date prior to September 30, 2008 if the failure of the Closing to have occurred on or before July 31, 2008 shall have resulted from the failure of the condition set forth in Sections 9.2 or
9.3 or Sections 10.2 or 10.3; provided, further, that the right to terminate this Agreement pursuant to this Section 12.1(e) shall not be available to any party whose failure to fulfill any of its
obligations contained in this Agreement has been the cause of, or resulted in, the failure of the Closing to have occurred on or prior to the aforesaid date. 
 Section 12.2 Notice of Termination. Any party desiring to terminate this Agreement pursuant to Section 12.1 shall give written notice of such termination to the other party to this
Agreement and shall include in reasonable detail the grounds for such termination. 
 Section 12.3 Effect of Termination.
If this Agreement shall be terminated pursuant to this Article XII, all further obligations of the parties under this Agreement (other than Sections 13.2 and 13.10) shall be terminated without further liability of any party to
the other; provided, however, that nothing herein shall relieve any party from liability for its willful breach of this Agreement. 
 Section 12.4 Specific Performance. The parties agree that irreparable damage would occur in the event that any of the terms or provisions of this Agreement related to the closing of the transactions contemplated hereby
were not performed in accordance with their specific wording or were otherwise breached. It is accordingly agreed that, notwithstanding anything to the contrary contained in this Agreement, each of the parties hereto shall be entitled to an
injunction or injunctions to prevent such breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States of America or any state having jurisdiction, such remedy being in addition to any
other remedy to which any party may be entitled at law or in equity.

respective successors and permitted assigns; provided, however, that neither party to this Agreement may assign its rights or delegate its obligations under this Agreement without the express prior written consent of the other party to
this Agreement; provided, further, that, notwithstanding the foregoing, subject to applicable regulatory approvals, Buyer may, without the prior written consent of Aon, assign to one or more of its wholly owned subsidiaries all or a
portion of its rights under this Agreement, provided that (1) no such assignment shall relieve Buyer of its obligations under this Agreement, (2) each wholly owned subsidiary of Buyer to which such rights have been assigned shall not
further assign, sublicense or transfer (directly or indirectly, by operation of law or otherwise) such rights to any Person other than another wholly owned subsidiary of Buyer and (3) any such assignment(s) shall not delay the Closing.

 Section 13.6 Access to Records after Closing. (a) For a period of six (6) years after the Closing Date, Aon
and its representatives shall have reasonable access to all of the books and records of the Company and the Subsidiaries to the extent that such access may reasonably be required by Aon in connection with matters relating to or affected by the
operations of the Company and the Subsidiaries prior to the Closing Date. Such access shall be afforded by Buyer upon receipt of reasonable advance notice and during normal business hours. Aon shall be solely responsible for any costs or expenses
incurred by it pursuant to this Section 13.6(a). If Buyer, the Company or the Subsidiaries shall desire to dispose of any of such books and records prior to the expiration of such six-year period, Buyer shall, prior to such disposition,
give Aon a reasonable opportunity, at Aon’s expense, to segregate and remove such books and records as Aon may select. 
  

 62 

 (b) For a period of six (6) years after the Closing Date, Buyer and its representatives shall have
reasonable access to all of the books and records relating to the Company and the Subsidiaries which Aon may retain after the Closing Date. Such access shall be afforded by Aon upon receipt of reasonable advance notice and during normal business
hours. Buyer shall be solely responsible for any costs and expenses incurred by it pursuant to this Section 13.6(b). If Aon shall desire to dispose of any of such books and records prior to the expiration of such six-year period, Aon
shall, prior to such disposition, give Buyer a reasonable opportunity, at Buyer’s expense, to segregate and remove such books and records as Buyer may select. 
 Section 13.7 Entire Agreement; Amendments. This Agreement, the Exhibits and Schedules referred to herein, the documents delivered pursuant hereto and the Confidentiality Agreement contain the entire
understanding of the parties hereto with regard to the subject matter contained herein or therein, and supersede all other prior representations, warranties, agreements, understandings or letters of intent between or among any of the parties hereto.
This Agreement shall not be amended, modified or supplemented except by a written instrument signed by an authorized representative of each of the parties hereto. 
 Section 13.8 Interpretation. Disclosure of any fact or item in any Schedule hereto referenced by a particular section in this Agreement shall be deemed to have been disclosed with respect to every
other section in this Agreement only to the extent such disclosure is reasonably clear on its face that it would apply to such other section. Neither the specification of any dollar amount in any representation or warranty contained in this
Agreement nor the inclusion of any specific item in any Schedule hereto is intended to imply that such amount, or higher or lower amounts, or the item so included or other items, are or are not material, and no party shall use the fact of the
setting forth of any such amount or the inclusion of any such item in any dispute or controversy between the parties as to whether any obligation, item or matter not described herein or included in any Schedule is or is not material for purposes of
this Agreement. Unless this Agreement specifically provides otherwise, neither the specification of any item or matter in any representation or warranty contained in this Agreement nor the inclusion of any specific item in any Schedule hereto is
intended to imply that such item or matter, or other items or matters, are or are not in the ordinary course of business, and no party shall use the fact of the setting forth or the inclusion of any such item or matter in any dispute or controversy
between the parties as to whether any obligation, item or matter not described herein or included in any Schedule is or is not in the ordinary course of business for purposes of this Agreement. To the extent that Aon becomes aware of any material
error in any Schedule prior to the Closing, Aon shall promptly notify the Buyer of the error. 
 Section 13.9 Waivers. Any
term or provision of this Agreement may be waived, or the time for its performance may be extended, by the party or parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this
Agreement if, as to any party, it is authorized in writing by an authorized representative of such party. The failure of any party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision,
nor in any way to affect the validity of this 

  

 63 

 
Agreement or any part hereof or the right of any party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall
be held to constitute a waiver of any other or subsequent breach. 
 Section 13.10 Expenses. Except as expressly set forth
herein, each party hereto will pay all costs and expenses incident to its negotiation and preparation of this Agreement and to its performance and compliance with all agreements and conditions contained herein on its part to be performed or complied
with, including the fees, expenses and disbursements of its counsel, independent public accountants and other advisors. 
 Section 13.11 Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such manner as to be effective and valid under applicable law, but in case any one or more of the provisions contained
herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the
remainder of such invalid, illegal or unenforceable provision or provisions or any other provisions hereof, unless such a construction would be unreasonable. 
 Section 13.12 Execution in Counterparts. This Agreement may be executed in counterparts, each of which shall be considered an original instrument, but all of which shall be considered one and the
same agreement, and shall become binding when one or more counterparts have been signed by each of the parties hereto and delivered to the other party. 
 Section 13.13 Further Assurances. Upon the terms and subject to the conditions herein, each of the parties hereto agrees to use its reasonable best efforts to take or cause to be taken all action,
to do or cause to be done, and to assist and cooperate with the other party in doing, all things necessary, proper or advisable under applicable Requirements of Law to consummate and make effective, in the most expeditious manner practicable, the
transactions contemplated by this Agreement, including: (i) the satisfaction of the conditions precedent to the obligations of any of the parties hereto; (ii) the defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the performance of the obligations hereunder; and (iii) the execution and delivery of such instruments, and the taking of such other actions, as the other party hereto may reasonably require in
order to carry out the intent of this Agreement. 
 Section 13.14 Disclaimer of Warranties. Aon makes no representations
or warranties with respect to any projections, forecasts or forward-looking information provided to Buyer. There is no assurance that any projected or forecasted results will be achieved. EXCEPT AS TO THOSE MATTERS EXPRESSLY COVERED BY THE
REPRESENTATIONS AND WARRANTIES IN THIS AGREEMENT, AON IS SELLING THE SHARES (AND THE BUSINESS AND ASSETS OF THE COMPANY AND THE SUBSIDIARIES REPRESENTED THEREBY) ON AN “AS IS, WHERE IS” BASIS AND AON DISCLAIMS ALL OTHER WARRANTIES,
REPRESENTATIONS AND GUARANTEES WHETHER EXPRESS OR IMPLIED. AON MAKES NO REPRESENTATION OR WARRANTY AS TO MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE AND NO IMPLIED WARRANTIES WHATSOEVER. Buyer acknowledges that neither Aon nor any of its
representatives or Affiliates or any other Person has made any representation or warranty, 

  

 64 

 
express or implied, as to the accuracy or completeness of any memoranda, charts or summaries heretofore made available by Aon or its representatives or
Affiliates to Buyer or any other information which is not included in this Agreement or the Schedules hereto, and none of Aon, nor any of its representatives or its Affiliates or any other Person will have or be subject to any liability to Buyer,
any Affiliate of Buyer or any other Person resulting from the distribution of any such information to, or use of any such information by, Buyer, any Affiliate of Buyer or any of their agents, consultants, accountants, counsel or other
representatives. Notwithstanding anything to the contrary in this Agreement, Buyer acknowledges and agrees that Aon makes no representation or warranty with respect to, and nothing contained in this Agreement, or in any other agreement, document or
instrument to be delivered in connection with the transactions contemplated hereby, is intended or shall be construed to be a representation or warranty (express or implied) of Aon, for any purpose under this Agreement or any other agreement,
document or instrument to be delivered in connection with the transactions contemplated hereby, with respect to (a) the adequacy or sufficiency of any of the reserves of the Underwriting Companies or (b) the effect of the adequacy or
sufficiency of reserves of the Underwriting Companies on any “line item” or asset, liability or equity amount. Buyer acknowledges and agrees that it is not entitled to rely upon any representations or warranties or other statements of fact
or opinion, other than the representations and warranties expressly set forth in this Agreement. 
 Section 13.15 Governing Law;
Submission to Jurisdiction. This Agreement shall be governed by and construed in accordance with the internal laws (as opposed to the conflicts of law provisions) of the State of New York. By the execution and delivery of this Agreement,
Buyer and Aon submit to the personal jurisdiction of any state or federal court in the State of New York in any suit or proceeding arising out of or relating to this Agreement. 
 Section 13.16 Waiver of Jury Trial. Each of Buyer and Aon hereby expressly waives any right to trial by jury in any dispute, whether
sounding in contract, tort or otherwise, between Buyer and Aon arising out of or related to the transactions contemplated by this Agreement or any of the Seller Ancillary Agreements or Buyer Ancillary Agreements, or any other instrument or document
executed or delivered in connection herewith or therewith. Either Buyer or Aon may file an original counterpart or a copy of this Agreement with any court as written evidence of the consent of the parties to the waiver of their right to trial by
jury.

	2.	CONDITIONS PRECEDENT 

 The provisions of

the Agent has received each of the documents listed in Schedule 1 (Conditions Precedent) in a form and substance satisfactory to it. The Agent shall notify the Obligors, the Banks and the New Bank promptly upon being so satisfied.

  

	3.	TRANSFER OF COMMITMENT 

  

	3.1	Transfer by novation 

  

	 	(a)	On the Effective Date (whether or not a Default is continuing), the Exiting Bank shall transfer by novation all of its Commitment, rights and obligations under the Finance Documents
to the New Bank, so that: 

  

	 	(i)	the Exiting Bank shall cease to be a Bank under the Restated Agreement and its Commitment shall be reduced to zero;

	 	(iii)	Schedule 1 (The Banks) of the Restated Agreement shall be amended by the deletion of “National Australia Bank Limited” and its replacement by “Citibank, N.A.,
Sydney Branch”. 

  

	 	(b)	The transfer by novation set out in Clause 3.1 (Transfer by novation) shall take effect on the Effective Date so that: 

  

	 	(i)	to the extent that in Clause 3.1 (Transfer by novation) the Exiting Bank seeks to transfer by novation its rights, benefits and obligations under the Finance Documents,
each of the Obligors and the Exiting Bank shall be released from further obligations towards one another under the Finance Documents and their respective rights against one another under the Finance Documents shall be cancelled (being the
“Discharged Rights and Obligations”); 

  

 - 2 - 

	 	(ii)	each of the Obligors and the New Bank shall assume obligations towards one another and/or acquire rights against one another which differ from the Discharged Rights and Obligations
only insofar as that Obligor and the New Bank have assumed and/or acquired the same in place of that Obligor and the Exiting Bank; 

  

	 	(iii)	the Agent, the Lead Arrangers, the New Bank and the Banks (other than the Exiting Bank) shall acquire the same rights and assume the same obligations between themselves as they
would have acquired and assumed had the New Bank been a Bank with the rights and/or obligations acquired or assumed by it as a result of the transfer and to that extent the Agent, the Lead Arrangers and the Banks (including the Exiting Bank) shall
each be released from further obligations to each other under the Finance Documents; and 

  

	 	(iv)	the New Bank shall become a party to the Restated Agreement as a “Bank”. 

  

	 	(c)	Any amounts payable to the Banks by the Obligors pursuant to any Finance Document on or before the Effective Date (including, without limitation, all interest, fees and commission
payable on the Effective Date) in respect of any period ending on or prior to the Effective Date shall be for the account of the Banks (including, for the avoidance of doubt, the Exiting Bank), and the New Bank shall not have any interest in, or any
rights in respect of, any such amount. 

  

	3.2	Limitation of responsibility of Existing Banks 

  

	 	(a)	The New Bank confirms to each Bank (including, for the purposes of paragraph (i) and (ii) only, the Exiting Bank) and the other Finance Parties that it:

  

	 	(i)	has received a copy of the Original Credit Agreement together with such other information as it has required in connection with this transaction; 

  

	 	(ii)	has made (and shall continue to make) its own independent investigation and assessment of the financial condition and affairs of each Obligor and its related entities in connection
with its participation in this Agreement and the Restated Agreement and has not relied exclusively on any information provided to it by any Bank in connection with any Finance Document; and 

  

	 	(iii)	will continue to make its own independent appraisal of the creditworthiness of each Obligor and its related entities whilst any amount is or may be outstanding under the Finance
Documents or any Commitment is in force. 

  

 - 3 - 

	 	(b)	Unless expressly agreed to the contrary, the Banks (including, for the avoidance of doubt, the Exiting Bank) make no representation or warranty and assume no responsibility to the
New Bank for: 

  

	 	(i)	the legality, validity, effectiveness, adequacy or enforceability of the Finance Documents or any other documents; 

  

	 	(ii)	the financial condition of any Obligor; 

  

	 	(iii)	the performance and observance by any Obligor of its obligations under the Finance Documents or any other documents; or 

  

	 	(iv)	the accuracy of any statements (whether written or oral) made in or in connection with the Finance Documents or any other document, 

 and any representations or warranties implied by law are excluded. 
  

	 	(c)	Nothing in any Finance Document obliges any Bank to: 

  

	 	(i)	accept a re-transfer from the New Bank of any of the rights and obligations transferred by novation under this Agreement; or 

  

	 	(ii)	support any losses directly or indirectly incurred by the New Bank by reason of the non-performance by any Obligor of its obligations under the Finance Documents or otherwise.

  

	3.3	Administrative Details 

 The New Bank confirms that
it has delivered to the Agent its Facility Office details and address, fax number and attention details for the purposes of Clause 33 (Notices) of the Restated Agreement. 
  

	4.	AMENDMENT AND RESTATEMENT 

 With effect from the
Effective Date, the Original Credit Agreement shall be amended and restated so that it shall be read and construed for all purposes as set out in Schedule 2 (Restated Agreement).
