The provisions of Section 5.1 of Annex A to the Contribution Agreement shall apply with respect to the compensation and benefit matters addressed in this Article VII. -13- 15 Section 7.2 Transfer of Employees. If a DEFS Employee or a PGC Employee is to be transferred to the Company pursuant to the terms of Annex A to the Contribution Agreement, then the Company may direct Duke and Phillips, respectively, to cause the transfer of such employee to be made to the Company or to a Subsidiary of the Company that is designated by the Company. Continued Employees may be employed by the Company or any Affiliate of the Company as determined by the Company from time to time in its sole discretion. Section 7.3 TEPPCO Employees. For all purposes of Annex A to the Contribution Agreement and this Article VII (except where specifically provided otherwise), each TEPPCO Employee shall be considered a Retained DEFS Employee. Duke shall have no obligation under Section 3.2 of Annex A to the Contribution Agreement to reimburse the Company for a pro-rata portion of the Bonuses for calendar year 2000 that are paid to Retained DEFS Employees who are TEPPCO Employees. Schedule 7.3 to this Agreement sets forth a list of agreements relating to TEPPCO Employees that shall be considered to be among the agreements listed in Schedule 2.5(a)(i) or Schedule 2.5(a)(ii) to Annex A to the Contribution Agreement (as indicated on Schedule 7.3 to this Agreement); provided, however, that the Company shall have no reimbursement obligation to Duke with respect to any such agreement that is considered to be among the agreements listed in Schedule 2.5(a)(i) to Annex A to the Contribution Agreement. Section 7.4 Welfare Benefits. (a) In order to permit benefits transition with respect to Retained DEFS Employees, for the period beginning on the date hereof and ending on the earliest of (i) December 31, 2000, (ii) such date as Duke shall cease to have a greater than 50%, direct or indirect, ownership interest in the Company, or (iii) such date as the Company or Duke shall designate with respect to any particular Old Welfare Plan (provided that Duke or the Company shall provide reasonable notice under the circumstances to the other party prior to any such date), the Company and/or its wholly-owned Subsidiaries shall be participating employers on behalf of their employees (including any Continued Employees) who meet the requirements for eligibility under the following Old Welfare Plans maintained by Duke: the Duke Energy Medical, Dental, Cafeteria (FSP), Basic Life Insurance, Supplemental and Dependent Life Insurance, Basic, Supplemental and Dependent Accidental Death and Dismemberment Insurance, Business Travel Accident Insurance and Long-Term Care Insurance Plans (each such Old Welfare Plan is herein referred to as a "Continued Duke Welfare Plan"); provided, however, that retiree medical, dental and life insurance coverages under the applicable Continued Duke Welfare Plans shall not become applicable to an individual who either is not a Retained DEFS Employee or fails to meet such requirements as Duke shall impose for such coverages. Duke may terminate the participation by the Company and its wholly-owned Subsidiaries in a particular Continued Duke Welfare Plan prior to December 31, 2000, pursuant to clause (iii) of the preceding sentence only if (1) Duke will be terminating such plan in its entirety as of the date designated by Duke pursuant to such clause or (2) Duke has determined that such continued participation by the Company and/or any of its wholly-owned Subsidiaries could subject Duke or such plan to fines, penalties, excise taxes, loss of tax deductions or other liabilities (other than liabilities for the benefits to be provided under such plan). Without limiting the generality of the preceding provisions of this Section 7.4(a), it is understood and agreed that such provisions shall not override the provisions of Section 4.2(b) of Annex A to the Contribution Agreement. For purposes of applying Section 4.5(c) of Annex A to the Contribution Agreement, the Continued Duke Welfare Plans shall be deemed to be New Welfare Plans; provided, however, that Eligible Expenses of a Retained DEFS Employee shall be determined without regard to when such expenses are recorded by the applicable plan administrator or reported to the Company. -14- 16 (b) Notwithstanding the provisions of Section 4.5(d) of Annex A to the Contribution Agreement, for the period specified in Section 7.4(a) as it applies to the Duke FSP, the Retained DEFS Employees shall continue to be eligible, and the Transferred PGC Employees shall be eligible, to participate in the Duke FSP. In the case of the Retained DEFS Employees, such continued participation shall be based on their elections under the Duke FSP that are in effect immediately prior to the date hereof (as such elections may be adjusted from time to time in accordance with the terms of the Duke FSP). In the case of the Transferred PGC Employees, the provisions of Section 4.5(d) of Annex A to the Contribution Agreement shall be applied as if the Duke FSP were the New FSP as defined therein, except that references therein to the Company shall be deemed to refer to Duke; provided, however, that if the aggregate amount of the transferred account balances of Transferred PGC Employees from the Phillips FSP to the Duke FSP is negative, then the Company shall pay Phillips the amount of such aggregate negative balance promptly following such account balance transfer. The parties hereto agree and acknowledge that it is their intention that the economic risks and benefits associated with calendar year 2000 (or any portion thereof) participation in the Duke FSP by Retained DEFS Employees (both before and after the date hereof), Transferred PGC Employees, and any other employees of the Company and its Subsidiaries be borne or enjoyed, as the case may be, by the Company. Accordingly, Duke and the Company agree that, as soon as administratively feasible after all claims under the Duke FSP have been processed for calendar year 2000 with respect to the employees of the Company and its Subsidiaries, one such party shall make a payment to the other (as appropriate) to ensure such result to the greatest extent possible. Section 7.5 Severance Benefits. (a) The Company or a Subsidiary of the Company shall reimburse Phillips for the cash severance benefit paid by Phillips or any Subsidiary of Phillips to certain of their employees in accordance with the terms of Article I of Exhibit A to that certain Transition Services Agreement between Phillips and the Company dated March 17, 2000. (b) Section 4.2(b) of Annex A to the Contribution Agreement shall apply to each Retained DEFS Employee who is a TEPPCO Employee and who was covered by the Change in Control Severance Plan immediately prior to the date hereof; provided, however, that (i) the Company shall not have any reimbursement obligation to Duke under such Section 4.2(b) with respect to the cash severance benefit paid to any such employee and (ii) Duke shall not have any reimbursement obligation to the Company under such Section 4.2(b) for any extended coverage under a welfare benefit plan. (c) The provisions of this Section 7.5(c) shall not apply with respect to any Retained DEFS Employee who is a TEPPCO Employee. Duke shall reimburse the Company or a Subsidiary of the Company for the severance benefit paid under the DEFS Severance Plan to any Retained DEFS Employee who receives notice from the Company or a Subsidiary of the Company on or about the date hereof that such individual's employment will be terminated in connection with (and in any event within 30 days after) the closing of the transactions contemplated under the Contribution Agreement. On or about the date hereof, the Company and its Subsidiaries shall also notify certain Retained DEFS Employees selected by the Company in its sole discretion that such individuals will be requested to perform services for the Company or a Subsidiary of the Company on only a transitional basis. Duke shall reimburse the Company or a Subsidiary of the Company for the severance benefit paid under the DEFS Severance Plan to any Retained DEFS Employee who receives the notice described in the preceding sentence provided that the termination of such individual's employment from the Company and its Affiliates occurs within six months of the date hereof (or within nine months of the date hereof in the case of such a Retained DEFS Employee who is an accountant). Section 7.6 Miscellaneous. The reference in Section 2.3 of Annex A to the Contribution Agreement to Section 6.1 of the Governance Agreement shall be deemed to refer to Section 6.1 of the Governance Agreement as in effect immediately before the termination of the Governance Agreement.
