If Mr. Surgenor elects to receive a lump sum payment, such payment will be made on the first day of the month coinciding with or next following the date Mr. Surgenor s employment terminates. Actuarial equivalence will be based on the actuarial assumptions specified from time to time in the retirement plan for lump sum payments.

SURVIVING SPOUSE BENEFIT 4.1 Eligibility. Mr. Surgenor's surviving spouse will receive the surviving spouse benefit if Mr. Surgenor and his spouse were married to each other for at least the 12 months preceding Mr. Surgenor's death and, in the case of Mr. Surgenor's death after retirement, Mr. Surgenor and his spouse were married to each other on Mr. Surgenor's date of retirement. 4.2 Amount of surviving spouse benefit. Subject to the reductions described in Section 6.2 below, the benefit provided under the plan to Mr. Surgenor's surviving spouse will be determined as follows: (a) Pre-retirement before age 63. If Mr. Surgenor dies during employment with TECO Energy and before his 63rd birthday, his surviving spouse will receive a monthly survivor income payment equal to 50 percent of his monthly projected retirement benefit. Mr. Surgenor's monthly projected retirement benefit is the monthly benefit he would have received if he had retired at age 63 under Section 3.1 calculated using his average annual earnings determined as of his date of death. (b) Pre-retirement on or after age 63. If Mr. Surgenor dies during employment with TECO Energy on or after his 63rd birthday, his surviving spouse will receive a monthly survivor income payment equal to 50 percent of his monthly retirement benefit earned under Section 3.1 using his average annual earnings as of his date of death. (c) Post-retirement. If Mr. Surgenor dies on or after the date of his retirement, his surviving spouse will receive a monthly survivor income payment equal to 50 percent of the monthly benefit payment he was receiving at his death (or would have received if he had survived until the first payment date). 4.3 Form and time of surviving spouse benefit. Surviving spouse benefits under this Section 4 will be payable only in the form of a life annuity to the surviving spouse. Benefit payments will begin on the first day of the month coinciding with or next following the date of Mr. Surgenor's death. 4.4 Death benefit where lump sum paid. If Mr. Surgenor received a lump sum payment of his benefit under Section 3.4(b), no surviving spouse benefit or other death benefit will be payable under the plan to any person. SECTION 5. DISABILITY 5.1 If Mr. Surgenor suffers a total disability (as defined in the disability income plan) before age 63, he will continue to be credited with service as if he were actively employed by TECO Energy during his period of total disability. Mr. Surgenor may not receive benefits under this plan at any time when he is receiving disability income payments under the disability income plan. Benefits under this plan will begin when payments cease under the disability income plan. - 207 - Exhibit 10.13 5.2 Mr. Surgenor's disability date is his last day of work for TECO Energy before becoming unable to continue working because of his total disability. A period of total disability of Mr. Surgenor will begin on his disability date and will end on the earlier of the last day of the month in which his final disability income payment is due under the disability income plan or on the date he retires hereunder and starts receiving benefit payments. 5.3 If Mr. Surgenor does not return to active service with TECO Energy after suffering a total disability, his retirement benefits under Section 3 will be calculated using his average annual earnings as of his disability date, his total service including service credited under Section 5.1 above, and his primary social security benefit as of his date of disability. 5.4 If Mr. Surgenor dies while disabled, his surviving spouse will, if eligible, receive the pre-retirement surviving spouse benefit determined under Section 4.2(a) or (b). SECTION 6. OFFSET FOR OTHER PAYMENTS 6.1 Mr. Surgenor's retirement benefit will be reduced (but not below zero) by the following payments, with such reductions starting when such payments are assumed to begin: (a) 100 percent of the social security benefit of Mr. Surgenor assuming such benefit begins on the later of the date he reaches age 63 or his actual retirement, and (b) the amount of his benefit payments under the retirement plan (converted to a life annuity if such payments are in an optional form), assuming such payments begin on the later of the date he reaches age 56 or his actual retirement. 6.2 The benefit of Mr. Surgenor's surviving spouse will be reduced (but not below zero) by the following payments: (a) payments under the survivor income plan, and (b) payments under the retirement plan. SECTION 7. BENEFITS NOT CURRENTLY FUNDED 7.1 Nothing in this plan will be construed to create a trust or to obligate TECO Energy or any other employer to segregate a fund, purchase an insurance contract, or in any other way currently to fund the future payment of any benefits hereunder, nor will anything herein be construed to give Mr. Surgenor or any other person rights to any specific assets of TECO Energy or of any other employer or entity. 7.2 Notwithstanding Section 7.1, TECO Energy has established a grantor trust of which it is treated as the owner under Section 671 of the Internal Revenue Code to provide for the payment of benefits hereunder. - 208 - Exhibit 10.13 SECTION 8. ADMINISTRATION The plan will be administered by the committee, which will have full power and authority to construe, interpret and administer the plan. Decisions of the committee will be final and binding on all persons. The committee may, in its discretion, adopt, amend and rescind rules and regulations relating to the administration of the plan. SECTION 9. RIGHTS NON-ASSIGNABLE Neither Mr. Surgenor, his surviving spouse, nor any other person will have any right to assign or otherwise to alienate the right to receive payments under the plan, in whole or in part. SECTION 10. OTHER BENEFIT PLANS This plan will supersede any obligation to pay benefits to Mr. Surgenor under the excess benefit plan contained in the retirement plan or the TECO Energy Group Supplemental Executive Retirement Plan, as they may be amended from time to time. No benefits will be payable to Mr. Surgenor under such excess benefit plan or the TECO Energy Group Supplemental Executive Retirement Plan. SECTION 11. AMENDMENT TECO Energy reserves the right at any time by action of the board to amend the plan in any way. However, no amendment of the plan may reduce the benefits to be paid to Mr. Surgenor or his surviving spouse below those that would have been paid if the plan had continued without change to the date of Mr. Surgenor's retirement or termination of employment for any reason.
