Exhibit 99.1


TO:		Mr. Sigman

FROM:		Cingular Wireless, LLC Board of Directors

DATE:		June 1, 2005

RE:		Employment at Cingular Wireless, LLC

The following outlines the terms of your continued employment at Cingular Wireless, LLC (“Cingular”), effective as of June 1, 2005.

1. Employment: You will remain employed by Cingular in Atlanta, Georgia as its President and Chief Executive Officer. Your employment will be employment at will, and either party may terminate your employment, with or without cause.

2. Retention Benefit: You shall be granted a retention benefit on June 1, 2005, in accordance with the terms set forth herein, which shall be valued at $5,000,000 as of the date of grant. Your right to receive the retention benefit shall vest and be payable on December 31, 2007; provided, if your employment is terminated by your death or permanent disability or by Cingular other than for cause, the retention benefit shall vest and be paid within thirty days of such termination of employment. If you otherwise quit or retire before the retention benefit vests, it shall be forfeited. The actual amount of the retention benefit shall be paid in cash and will be calculated by determining the number of shares of each of SBC and BellSouth stock that could be purchased at the closing prices of such stocks on the grant date (based on a ratio of 60% SBC stock and 40% BellSouth stock) (the equivalent number of shares of each of SBC and BellSouth stock, respectively, shall be referred to as “Share Equivalents”) and paying you the value of such Share Equivalents based on the closing prices of SBC and BellSouth stock on the vesting date. On each date dividends are paid on SBC or BellSouth stock you shall receive dividend equivalents on the retention benefit equal to the dividend on a share of the stock paying the dividend multiplied by number of Share Equivalents of the relevant company you hold on the record date for such dividend where such record date occurs prior to the vesting or forfeiture of the Share Equivalents. In the event of a stock dividend, stock split, merger or other change in the corporate structure, the number of the Share Equivalents shall be reasonably adjusted to prevent dilution or enlargement of rights.

3. Base Pay, Short-Term Pay and Long-Term Pay: Provided you continue to be employed by Cingular (or its successor), (i) your annual rate of base pay shall not be less than $1,105,000, subject to such increases, if any, as the Board of Directors of Cingular shall from time to time approve (“Base Pay”), (ii) your annual short-term target shall be 125% of your Base Pay, and (iii) your annual long-term target shall be valued at 475% of your Base Pay on the grant date. You shall receive a gross up for Georgia income tax on your Base Pay, the actual amount of your short-term award, and the actual amount of your long-term award paid under the Cingular long-term incentive plan, but only to the extent any of such payments are subject to Georgia income tax. Your long-term awards described in item (iii) above shall be granted under and governed by the terms of the

Cingular long-term incentive plan, however, for purposes of vesting, your service with SBC will be recognized. Your long-term awards under the Cingular long-term incentive plan may be subject to adjustment based on the accomplishment of Cingular performance objectives. They will be paid in cash, unless, on the payment date, Cingular (or its successor) is a publicly-traded entity, in which event your long-term award could be paid in cash or equity of Cingular (or its successor), at the option of Cingular (or its successor).

4. Incentive Payments: Cingular (or its successor) will pay you (i) $675,000 on or about June 1, 2005, and (ii) $160,000 on or about November 24, 2005, $160,000 on or about November 24, 2006 and $160,000 on or about November 24, 2007, provided you are employed by Cingular (or its successor) on each of the foregoing payment dates. Each of these payments will be grossed up for Georgia state income tax. $60,000 of each of the payments of $160,000 (described in clause (ii) above) will also be grossed up for federal income tax.

5. Supplemental Pension Benefit: You will be eligible to continue participation and accrue benefits in the 2005 SBC Supplemental Employee Retirement Plan (“SERP”) during your employment at Cingular. Your SERP benefit shall be paid by SBC in accordance with the terms of the SBC SERP. The non-grossed up amount of your Base Pay and $100,000 of each of your Incentive Payments of $160,000 (referred to in clause (ii) of paragraph 4, above), which is considered salary for the SBC SERP, and the non-grossed up amount of your actual short-term award plus the $675,000 payment described in clause (i) above (non-grossed up), will be eligible “earnings” for purposes of your SBC SERP calculation. Your SBC SERP benefit will be offset by the amount of any qualified and/or nonqualified pension benefits that you receive or received from plans sponsored by SBC or Cingular. Your will not be eligible to accrue benefits in the Cingular SRIP or SERP during any period of time that you are accruing benefits in the SBC SERP.

6. Income Tax Gross Up Calculation: The payments described in Paragraphs 3 and 4 that are subject to Georgia income tax and other compensation you receive from SBC and/or Cingular that is subject to Georgia income tax, except the Retention Benefit, will be grossed up for Georgia income tax. In addition, $60,000 of each of the payments of $160,000 described in clause (ii) of Paragraph 4 will be grossed up for federal income tax.
