                         IMPROVED CORPORATE GOVERNANCE
                         FOR AT&T COMCAST SHAREHOLDERS
--------------------------------------------------------------------------------


Comcast
-------

o    Roberts family has 3% of stock but 87% of vote

o    Roberts family controls all matters requiring shareholder approval

o    Comcast shareholders have few corporate governance-based rights




AT&T Comcast
-----------

o    Roberts family voting rights limited to 33% of voting rights

o    For 10 years:

     *    Roberts family cannot receive a control premium not shared with public
          shareholders

     *    Roberts family cannot sell shares outside family without approval of
          public shareholders

o    Majority of Board to consist of independent directors

o    For 2005 election and beyond, independent directors are the majority of
     the nominating committee

o    Shareholders have right to elect all directors after first full year of
     new Company's operations

o    Annual election of all directors (67% of S&P 500 companies have
     staggered elections)

o    Shareholders have ability to nominate and replace directors

                        RISKS OF VOTING AGAINST THE AT&T
                           COMCAST CHARTER PROVISION
--------------------------------------------------------------------------------


o    Voting down the charter provision effectively terminates the merger

o    Failure to complete merger leaves AT&T with a large debt burden

o    Alternative debt-reduction strategies could result in lower value for
     AT&T shareholders, have onerous tax consequences, and have execution risk

o    Other strategic alternatives offered less attractive economics and
     corporate governance, and higher execution risks

o    No assurance that Comcast will renegotiate charter provisions




15                                                                   [AT&T LOGO]





                          AT&T CONSUMER TRACKING STOCK
                                    PROPOSAL
--------------------------------------------------------------------------------


o    Maximize value to shareholders by creation of separate securities for
     distinctly different businesses

     *    Consumer - income-oriented investors

     *    Business - value-oriented investors

o    Due to regulatory and financial limitations, tracking stock was best
     alternative

o    Anticipated to be a tax-free distribution to shareholders; not a
     targeted public offering

o    Issue when and if appropriate market receptivity exists

o    Expected to have a meaningful dividend

o    No negative corporate governance tie-ins bundled into creation of
     tracking stock

     *    Tracking stock incentive thresholds and employee stock purchase plans
          meet ISS guidelines
