Section 1. Registrant's Business and Operations

Item 1.01. Entry into a Material Definitive Agreement

     On January 18, 2005, our Compensation and Employee Benefits  Committee (the
Committee)  exercised its discretion to approve  adjustments to the  performance
metrics for the Company's  2004 Bonus Plan to exclude the net income  impacts of
the Company's asset impairment charge,  business  restructuring charge and three
other  non-operating  events.  The Committee also  established  the  performance
metrics for the Company's  2005 Bonus Plan which will be based on 50% net income
and 50% revenue, and a discretionary modifier (plus or minus up to 25%) based on
competitive  performance.  The Company's  senior  executives  participate in the
Company's  Bonus  Plans  subject to the terms of the AT&T  Short Term  Incentive
Program,  as  amended,  filed by the Company as Exhibit  (10)(iii)(A)(1)  to its
Quarterly  Report on Form 10-Q for the  quarterly  period  ended  March 31, 2004
(Commission file number 1-1105).

     The Committee approved effective January 20, 2005 a payout level of 100% of
target for performance share awards for senior  executives  outstanding from the
2002-2004  performance cycle. These performance share awards were made under the
Company's 1997 Long Term Incentive Program, as amended,  filed by the Company as
Exhibit  (10)(iii)(A)(2)  to its Annual Report on Form 10-K for 1997 (Commission
file number 1-1105).  In addition,  the Committee approved the 2005 compensation
structure for equity awards, which in the case of senior executives will consist
of 70% performance  shares for a 2005-2007  performance cycle and 30% restricted
stock units.  The performance  criteria for outstanding  performance  shares for
2005  will be the same as those  established  under  the 2005  Bonus  Plan.  The
restricted  stock  units  will vest 50%  after two years and 25% each  after the
third and fourth year.  The Company's  equity awards for 2005 will be made under
the Company's 2004 Long Term Incentive  Plan,  which was filed by the Company as
Exhibit 4.1 to Form S-8 filed May 26, 2004 (Commission file number 333-115909).

     The  2004  Bonus  Plan  payments,  and 2005  restricted  stock  awards  and
performance  share awards,  approved by the Committee for AT&T's named executive
officers based upon 2004 compensation are set forth in the table below:
