For the "Severance Period," as hereinafter defined, Executive shall receive biweekly payments equal to the greater of (a)(i) the quotient of $1,000,000 and 36 if the Severance Event occurs within 24 months of the Effective Date or (ii) the quotient of $700,000 and 24 if the Severance Event occurs more than 24 months after the Effective Date but within 36 months of the Effective Date and (b) and amount equal to 1/26 of (i) Executive's annualized base salary at the effective date of termination, plus (ii) one-half of the total of any bonus or incentive compensation (but not including any special or one-time bonus or incentive compensation payments) paid or payable to Executive for the two most recent calendar years or other periods generally used by UHS to determine such bonus or incentive compensation, or if Executive has been eligible for such bonus or incentive compensation payments for less than two such periods, the last such payment paid or payable to Executive (the amounts paid pursuant to (a) or (b) are referred to as the "Severance Compensation"). The Severance Compensation shall be reduced by any compensation which Executive receives or reasonably could have received in each biweekly period as a result of employment or work as an independent contractor elsewhere. Executive shall promptly disclose to UHS any such compensation. For purposes of this Agreement, the "Severance Period" shall equal: 13 months if a Severance Event occurs within 24 months of the Effective Date; 12 months if a Severance Event occurs more than 24 but within 36 months of the Effective Date; and such period of time as is consistent with UHS' then prevailing severance policies for executive officers comparable to the Executive if a Severance Event occurs more than 36 months after the Effective Date. Any payments hereunder will be reduced by all applicable withholdings or deductions required by law or Executive's elections under any employee benefit plans which Executive continues to participate in under Section 3C2. If a Severance Event occurs more than 36 months after the Effective Date in connection with a change of control of UHC Executive shall receive Severance Compensation equal to the greater of $700,000 or such amount as is payable in accordance with UHC's prevailing policies. 2. As of the effective date of termination of employment, Executive shall cease to be eligible for all benefit plans maintained by UHS, except as required by federal or state continuation of coverage laws. If Executive elects continuation of coverage under one or more benefit plans subject to such continuation requirements, UHS shall, for the Severance Period, pay on behalf of Executive an amount equal to UHS's employer contribution for similarly situated active employees' coverages under such benefit plans. During the Severance Period Executive's share of coverage costs for such benefit plans shall be deducted automatically through after-tax payroll deduction from the Severance Compensation. 3. During the Severance Period UHS shall pay to an outplacement firm selected by UHS an amount deemed reasonable by UHS for outplacement and job search services for Executive. 4. Executive shall be paid a portion of the Management Incentive Program payments for the year in which termination of this Agreement occurs and shall also be entitled to a position of the payments under the Long-Term Incentive Plan. Payments shall be prorated based on the time at which this Agreement terminates and shall be paid promptly following their determination in accordance with the plan. 3 The payments and benefits to Executive under this Section 3C shall be the sole liability of UHS to Executive in the event of a Severance Event and shall replace and be in lieu of any payments or benefits which otherwise might be owned by UHS under any other severance plan or program and such payments and benefits may be conditioned by UHS upon receipt of a release of claims from Executive. D. DEFINITION AND PROCEDURE. 1. For purposes of this Agreement, "Cause" shall mean (a) the refusal of Executive to follow the reasonable directions of UHS's Board of Directors or Executive's supervisor or to perform any duties reasonably required on material matters by UHS, (b) material violations of UHS's Code of Conduct or (c) the commission of any criminal act or act of fraud or dishonesty by Executive in connection with Executive's employment by UHS. Prior to the termination of Executive's employment under subsection (a) of this Cause definition. UHS shall provide Executive with a 30 day notice specifying the basis for Cause. If the Cause described in the notice is cured to UHS's reasonable satisfaction prior to the end of the 30 day notice period, Executive's employment shall not be terminated on that basis. 2. For purposes of this Agreement a "Change in Employment" shall be deemed to have occurred (a) if (i) Executive's duties are materially adversely changed without Executive's prior consent or (ii) Executive's salary or benefits are reduced other than as a general reduction of salaries and benefits by UHS or (iii) without terminating Executive's employment this Agreement is terminated by UHS pursuant to Section 3B2, and (b) if in each case under subsections (a) (i), (ii), and (iii), in the period beginning 60 days before the time the Change in Employment occurs, Cause does not exist or if Cause does exist UHS has not given Executive written notice that Cause exists. Executive may elect to treat a Change in Employment as a termination of employment by UHS. To do so Executive shall send written notice of such election to UHS within 60 days after the date Executive receives notice from UHS or otherwise is definitely informed of the events constituting the Change in Employment. No change in Employment shall be deemed to have occurred if Executive fails to send the notice of election within the 60 day period. Executive's failure to treat a particular Change in Employment as a termination of employment shall not preclude Executive from treating a subsequent Change in Employment as a termination of employment. The effective date of a Change in Employment termination shall be the date 30 days after UHS receives the written notice of election. 4.
