(a)    An amount equal to the Executive’s annual base salary (as in effect immediately prior to the Termination Date), payable in a cash lump sum on the fifty-third (53^rd) day following the Termination Date.

5.    Payments and Benefits Upon a CIC Qualifying Termination. In the event that an Executive experiences a CIC Qualifying Termination, the Company shall pay to the Executive (or Executive’s beneficiary or estate, as the case may be) the Accrued Benefits and the Severance Benefits described below:

(a)    An amount equal to the Executive’s average annual cash incentive bonus over the three fiscal years immediately preceding the fiscal year in which the Termination Date occurs (annualized for any fiscal year with respect to which the Executive was employed by the Company for fewer than twelve (12) months), multiplied by a fraction, the numerator of which is the number of days elapsed in the fiscal year in which the Termination Date occurs through the Termination Date, and the denominator of which is 365 or 366 (as applicable), payable in a cash lump sum on the fifty-third (53^rd) day following the Termination Date (provided however, that (i) if the Executive was not employed by the Company during each of the three fiscal years immediately preceding the fiscal year in which the Termination Date occurs, the amount shall be determined based on the average annual cash incentive bonus received by the Executive over the fiscal years in which the Executive was actually employed; and (ii) if the Executive has not received an annual cash incentive bonus at any time prior to the Termination Date due to having been a new hire, the amount shall be determined by reference to the Executive’s target annual cash incentive opportunity);

(b)    An amount equal to two (2) times the sum of (i) the Executive’s annual base salary (as in effect immediately prior to the Termination Date, or immediately prior to any reduction if such CIC Qualifying Termination is a result of a reduction in base salary) and (ii) the Executive’s average annual cash incentive bonus over the two fiscal years immediately preceding the fiscal year in which the Termination Date occurs, payable in a cash lump sum on the fifty-third (53^rd) following the Termination Date (provided however, that (x) if the Executive was not employed by the Company during each of the two fiscal years immediately preceding the fiscal year in which the Termination Date occurs, the amount shall be determined based on the average annual cash incentive bonus received by the Executive over the fiscal years in which the Executive was actually employed; and (y) if the Executive has not received an annual cash incentive bonus at any time prior to the Termination Date due to having been a new hire, the amount shall be determined by reference to the Executive’s target annual cash incentive opportunity);

(c)    For U.S. Executives only: immediate and full vesting in the Executive’s accrued benefits under the Aon Corporation Excess Benefit Plan, the Aon Corporation Supplemental Savings Plan (the “SSP), and the Aon Corporation Supplemental Employee Stock Ownership Plan, or successor plans in effect on the Termination Date; provided that (i) the accrued benefits under the Aon Corporation Excess Benefit Plan or the SSP (whichever plan applies to the Executive) shall be determined by crediting the Executive with two (2) additional years of age and service credits, and (ii) the accrued benefits under the SSP shall be determined by crediting the Executive’s SSP account with an amount equal to two (2) additional years of Supplemental Match Contributions (as defined under, and calculated based on the Executive’s Years of Participation under, the SSP as of the Termination Date); and

(d)    For the period commencing on the Termination Date and ending on the earlier of (i) two (2) years following the Termination Date and (ii) the date on which the Executive becomes eligible

to participate in and receive medical, dental and life insurance benefits under a plan or arrangement sponsored by another employer having benefits substantially equivalent to the benefits provided pursuant to this subsection, the Company shall continue the Executive’s medical, dental and life insurance coverage, under the Company-sponsored plans or otherwise, upon the same terms and otherwise to the same extent as such coverage shall have been in effect immediately prior to the Executive’s Termination Date, and the Company and the Executive shall share the costs of the continuation of such medical, dental and life insurance coverage in the same proportion as such costs were shared immediately prior to the Termination Date; provided that the Company’s share of the cost of the continuation of coverage under any self-insured medical reimbursement plan that is subject to Section 105(h) of the Code shall be included in the Executive’s taxable income from the Company. Such continuation of coverage shall be in satisfaction of the Company’s obligations under the Consolidated Omnibus Budget Reconciliation Act of 1985, to the extent applicable. Notwithstanding the foregoing, if the Company determines in its sole discretion that it cannot provide the foregoing continuation of benefits without potentially violating applicable law (including, without limitation, Section 2716 of the U.S. Public Health Service Act), the Company shall, in lieu of such benefits, provide Executive with a taxable cash payment equal to one-hundred percent (100%) of the portion of the applicable monthly premium the Company would pay for such coverage as in effect at such time, for each calendar month (including partial months) remaining until the earlier of (i) second anniversary of the Termination Date and (ii) the date on which the Executive becomes eligible to participate in and receive such benefits under a plan or arrangement sponsored by another employer.

6.    Release of Claims. Any Severance Benefits payable to an Executive under the Plan shall only be paid contingent upon the Executive’s (or, in the event of the Executive’s death or incapacity, that of the Executive’s executor or other legal representative) execution and non-revocation of the Company’s standard non-competition, non-solicitation of clients and employees, and confidentiality agreement and release of claims, as modified in the Company’s sole discretion to preserve the enforceability of such agreement under applicable local law (the “Release”) within forty-five (45) days following the Termination Date. For the avoidance of doubt, the Severance Benefits shall be provided as compensation for services rendered to the Company and in consideration of the covenants set forth in the Release. The Executive shall forfeit the Severance Benefits in the event that the Executive fails to execute and deliver the Release to the Company in accordance with the timing and other provisions of this Section or revokes such Release prior to the date it becomes effective.

7.    Reduction of Payments. Anything in this Plan to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Company to or for the benefit of the Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Plan or otherwise, but determined without regard to any adjustment required under this Section) (in the aggregate, the “Total Payments”) would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter referred to as the “Excise Tax”), and if it is determined that (a) the amount remaining, after the Total Payments are reduced by an amount equal to all applicable federal and state taxes (computed at the highest applicable marginal rate), including the Excise Tax, is less than (b) the amount remaining, after taking into account all applicable federal and state taxes (computed at the highest applicable marginal rate), after payment or distribution to or for the benefit of the Executive of the maximum amount that may be paid or distributed to or for the benefit of the Executive without resulting in the imposition of the Excise Tax, then the payments due hereunder shall be reduced so that the Total Payments are One Dollar ($1) less than such maximum amount. All determinations to be made pursuant to this Section 7 shall be made by the public accounting firm that serves as the Company’s auditor.

8.    Section 409A.

(a)    A termination of employment shall not be deemed to have occurred for purposes of any provision of this Plan providing for the payment of any amounts or benefits that are subject to the requirements of Section 409A upon or following a termination of employment, unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment,” or like terms shall mean “separation from service” within the meaning of Section 409A.

(b)    Each payment to be made to an Executive under this Plan shall be treated as a “separate payment” for purposes of Section 409A.

(c)    In the event that any payment or distribution or portion of any payment or distribution to be made to the Executive hereunder cannot be characterized as a “short term deferral” for purposes of Section 409A or is not otherwise exempt from the provisions of Section 409A, and the Executive is determined to be a “specified employee” under Section 409A, such portion of the payment shall be delayed until the earlier to occur of the Executive's death or the date that is six (6) months and one day following the Executive's “separation from service” within the meaning of Section 409A (the “Delay Period”). Upon the expiration of the Delay Period, the payments delayed pursuant to this subsection shall be paid to the Executive or his or her beneficiary in a lump sum, and any remaining payments due under this Plan shall be payable in accordance with their original payment schedule.

(d)    To the extent that the reimbursement of any expenses or the provision of any in-kind benefits under this Plan is subject to Section 409A, (i) the amount of such expenses eligible for reimbursement, or in-kind benefits to be provided, during any one calendar year shall not affect the amount of such expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year; (ii) reimbursement of any such expense shall be made by no later than December 31 of the year following the year in which such expense is incurred; and (iii) the Executive’s right to receive such reimbursements of in-kind benefits shall not be subject to liquidation or exchange for another benefit.

(e)    The time or schedule of any payment or amount scheduled to be paid pursuant to the terms of this Plan may not be accelerated except as otherwise permitted under Section 409A.

(f)    The parties intend that this Plan and the benefits provided hereunder be interpreted and construed to comply with Section 409A to the extent applicable thereto, including the exceptions for short-term deferrals, separation pay arrangements, reimbursements, and in-kind distributions. Notwithstanding any provision of the Plan to the contrary, the Plan shall be interpreted and construed consistent with this intent, provided that the Company shall not be required to assume any increased economic burden in connection therewith. To the extent that any provision of this Plan would fail to comply with the applicable requirements of Section 409A, the Company may, in its sole and absolute discretion, make such modifications to the Plan and/or payments to be made thereunder to the extent it determines necessary or advisable to comply with the requirements of Section 409A; provided, however, that the Company shall in no event be obligated to pay any interest, compensation, or penalties in respect of any such modifications. Although the Company intends to administer the Plan so that it will comply with the requirements of Section 409A, the Company does not represent or warrant that the Plan will comply with Section 409A or any other provision of federal, state, local, or non-United States law. Neither the Company, its Subsidiaries, nor their respective directors, officers, employees or advisers shall be liable to the Executive (or any other individual claiming a benefit through the Executive) for any tax, interest, or penalties the Executive may owe as a result of compensation paid under the Plan, and the Company and its Subsidiaries shall have no obligation to indemnify or otherwise protect the Executive from the obligation to pay any taxes pursuant to Section 409A.

9.    Plan Administration; Claims Procedure.

All questions arising in connection with the interpretation of this Plan or its administration shall be submitted to and determined by the Plan Administrator in a fair and equitable manner in accordance with the procedure for claims and appeals described below.

The Plan Administrator shall, within ninety (90) days after receipt of such written claim (unless special circumstances require an extension of time, but in no event more than one hundred and eighty (180) days after such receipt), send a written notification to the Executive as to the disposition of such claim. Such notification shall be written in a manner calculated to be understood by the claimant and in the event that such claim is denied in whole or in part, shall (i) state the specific reasons for the denial, (ii) make specific reference to the pertinent Plan provisions on which the denial is based, (iii) provide a description of any additional material or information necessary for the Executive to perfect the claim and an explanation of why such material or information is necessary, and (iv) set forth the procedure by which the Executive may appeal the denial of such claim.

Such Executive (or his or her duly authorized representative) may, upon written request to the Plan Administrator, review any documents pertinent to such claim, and submit in writing issues and comments in support of such claim. Within 60 days after receipt of a written appeal (unless special circumstances require an extension of time, but in no event more than one hundred and twenty (120) days after such receipt), the Plan Administrator shall notify the Executive of the final decision with respect to such claim. Such decision shall be written in a manner calculated to be understood by the claimant and shall state the specific reasons for such decision and make specific references to the pertinent Plan provision on which the decision is based.

(c)    The Plan Administrator may from time to time delegate any of his or her duties hereunder to such person or persons as the Plan Administrator may designate. The Plan Administrator is empowered, on behalf of this Plan, to engage accountants, legal counsel and such other persons as the Plan Administrator deems necessary or advisable for the performance of his or her duties under this Plan.

11.    Amendment and Termination. The Company shall have the right, in its sole discretion, pursuant to action by the Board, to approve the amendment or termination of this Plan, which

amendment or termination shall not become effective until the date fixed by the Board for such amendment or termination, which date, in the case of an amendment which would be materially adverse to the interests of any Executive or in the case of termination, shall be at least one hundred and twenty (120) days after notice thereof is given by the Company to the Executives; provided, however, that no such action shall be taken by the Board during any period when the Board has actual knowledge that any person has taken steps reasonably calculated to effect a Change in Control until, in the opinion of the Board, such person has abandoned or terminated its efforts to effect a Change in Control; and provided further, that during the CIC Period or any period thereafter during which payments or benefits payable under the terms of this Plan as a result of a CIC Qualifying Termination, in no event shall this Plan be amended in a manner materially adverse to the interests of any Executive or terminated.

12.    Offset; Mitigation.

(a)    For non-U.S. Executives who are not subject to U.S. federal income tax: If the Company is obligated by law to pay severance pay, notice pay or other similar benefits, or if the Company is obligated by law to provide advance notice of separation (“Notice Period”), then any payments hereunder shall be reduced by the amount of any such severance pay, notice pay or other similar benefits, as applicable, and by the amount of any severance pay, notice pay or other similar benefits received during any Notice Period.

(b)    In no event shall an Executive be obligated to seek other employment or to take other action by way of mitigation of the amounts payable and the benefits provided to such Executive under any of the provisions of this Plan, and such amounts and benefits shall not be reduced whether or not such Executive obtains other employment, except as otherwise provided in Section 5(d) hereof.

13.    Unfunded Plan. This Plan shall not be funded. No Executive entitled to benefits hereunder shall have any right to, or interest in, any specific assets of the Company or any of its Subsidiaries, but an Executive shall have only the rights of a general creditor of the Company to receive benefits on the terms and subject to the conditions provided in this Plan.

14.    Payments to Minors, Incompetents and Beneficiaries. Any benefit payable to or for the benefit of a minor, an incompetent person or other person incapable of giving a receipt therefor shall be deemed paid when paid to such person’s guardian or to the party providing or reasonably appearing to provide for the care of such person, and such payment shall fully discharge the Company, its Subsidiaries, the Plan Administrator and all other parties with respect thereto. If an Executive shall die while any amounts would be payable to the Executive under this Plan had the Executive continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Plan to such person or persons appointed in writing by the Executive to receive such amounts or, if no person is so appointed, to the estate of the Executive.

15.    Non-Assignability. None of the payments, benefits or rights of any Executive shall be subject to any claim of any creditor, and, in particular, to the fullest extent permitted by law, all such payments, benefits and rights shall be free from attachment, garnishment, trustee’s process or any other legal or equitable process available to any creditor of such Executive. Except as otherwise provided herein or by law, no right or interest of any Executive under this Plan shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation by execution, levy, garnishment, attachment or pledge; no attempted assignment or transfer thereof shall be effective; and no right or interest of any Executive under this Plan shall be subject to any obligation or liability of such Executive.

16.    No Rights to Continued Employment. Neither the adoption of this Plan, nor any amendment hereof, nor the creation of any fund, trust or account, nor the payment of any benefits, shall be construed as giving any Executive the right to be retained in the service of the Company or any of its Subsidiaries, and all Executives shall remain subject to discharge to the same extent as if this Plan had not been adopted.

17.    Successors; Binding Agreement. This Plan shall inure to the benefit of and be binding upon the beneficiaries, heirs, executors, administrators, successors and assigns of the parties, including each Executive, present and future, and any successor to the Company or one of its Subsidiaries. This Plan shall not be terminated by any merger or consolidation of the Company whereby the Company is or is not the surviving or resulting corporation or as a result of any transfer of all or substantially all of the assets of the Company. In the event of any such merger, consolidation or transfer of assets, the provisions of this Plan shall be binding upon the surviving or resulting corporation or the person or entity to which such assets are transferred. The Company agrees that concurrently with any merger, consolidation or transfer of assets referred to in this Section, it will cause any surviving or resulting corporation or transferee unconditionally to assume all of the obligations of the Company hereunder.
