                                                            Exhibit 10(iii)(A)3

                Summary of Actions Relating to Change in Control

On October 23, 2000, the Board of Directors of AT&T Corp. ("AT&T") approved
board resolutions (incorporated by reference of Exhibit (10)(iii)(A)(32) to
Form 10-K for 2000, File No. 1-1105) adopting change in control provisions to
various AT&T plans and programs (collectively, as further amended subsequent to
the date of such resolutions, the "Plans"). The Plans were amended to provide
enhanced benefits to participants whose employment is terminated under certain
circumstances within two years following a change in control. The definition of
"Change in Control" used in these amendments was the definition contained in
the AT&T 1997 Long Term Incentive Program (incorporated by reference to Exhibit
10(iii)(A)(12) to Form 10-K for 1999, File No. 1-1105).

On February 23, 2004, the Board of Directors of AT&T adopted, subject to
shareholder approval, the AT&T 2004 Long Term Incentive Program that, among
other things, includes a definition of "Change in Control" that differs from
the definition that appears in the AT&T 1997 Long Term Incentive Program. At
the AT&T annual meeting on May 19, 2004, the AT&T shareholders approved the
AT&T 2004 Long Term Incentive Program (incorporated by reference to Exhibit 4.1
to Form S-8 filed on May 26, 2004, File No. 1-1105).

Subsequent to the AT&T shareholders meeting, officers and internal benefits
committees of AT&T, with the concurrence of the Chairman of the Compensation
and Employee Benefits Committee of the Board of Directors, took various actions
the effect of which was to further amend the Plans to substitute the definition
of "Change in Control" contained in the AT&T 2004 Long Term Incentive Program
for the definition of "Change in Control" contained in the AT&T 1997 Long Term
Incentive Program.<PAGE>

                                                             EXHIBIT 10(iii)(A)4

                                   AT&T CORP.

              DEFERRED COMPENSATION PLAN FOR NON-EMPLOYEE DIRECTORS

                            (as amended May 18, 2004)

1.    Eligibility

            Each member of the Board of Directors ("Board") of AT&T Corp.
      ("Company") who is not an employee of the Company, or of any of its
      subsidiaries, is eligible to participate in a Deferred Compensation Plan
      for Non-Employee Directors ("Plan").

2.    Participation

            (a) Prior to the beginning of any calendar year, or, in the case of
      newly elected Directors, within 90 days of such election, each eligible
      Director may elect to participate in the Plan by directing that all or any
      part of the compensation which would otherwise have been payable currently
      for services as a Director (including fees payable for services as a
      member of a committee of the Board and any shares of AT&T common stock
      resulting from the vesting of a restricted stock unit award) during such
      calendar year, or, in the case of newly elected Directors, during the
      remainder of such calendar year, shall be credited to a deferred
      compensation account subject to the terms of the Plan.

            (b) Such an election to participate in the Plan shall be in the form
      of a document executed by the Director and filed with the Secretary of the
      Company. An election related to fees, or shares of AT&T common stock
      otherwise payable currently in any calendar year shall become irrevocable
      on the last day prior to the beginning of such calendar year, or, in the
      case of new Directors, on the 90th day after becoming a Director. An
      election shall continue until a Director ceases to be a Director or until
      he or she terminates or modifies such election by written notice. Any such
      termination or modification shall become effective as of the end of the
      calendar year in which such notice is given with respect to all fees or
      shares otherwise payable in subsequent calendar years. A Director who has
      filed a termination of election may thereafter again file an election to
      participate for any calendar year or years subsequent to the filing of
      such election

            (c) Also, a Director's deferred compensation account automatically
      shall be credited with that part of the Director's compensation for any
      calendar year (including fees for services as a member of the Board), if
      any, which the Board has directed to be credited under this Plan. Such
      compensation shall be credited at the time that the related compensation
      is or would otherwise have been paid currently.

3.    Deferred Compensation Accounts

            (a) At the time of election to participate in the Plan under Item 2
      (a) above, a Director shall also designate the percentage of such deferred
      amounts constituting fees to be credited to the AT&T Shares portion of the
      Director's deferred account and the percentage to be credited to the Cash
      portion of such account. All shares of AT&T stock resulting from the
      vesting of restricted stock unit awards and deferred amounts credited
      under Item 2 (c) above shall be credited to the AT&T Shares portion of the
      Director's deferred account.

            (b) Deferred AT&T Shares. Deferred amounts constituting fees
      credited to the AT&T Shares portion of a Director's account on the date
      the related compensation is or would be otherwise paid shall be converted
      to a number of deferred AT&T Shares, determined by dividing the amount of
      such compensation by the price of AT&T common shares, as determined in the
      last sentence of this paragraph. The Director's account shall also be
      credited on each dividend payment date for AT&T Shares with an amount
      equivalent to the dividend payment on the number of AT&T common shares
      equal to the number of deferred AT&T Shares in the Director's account on
      the record date of such dividend. Such amount shall then be converted to a
      number of additional deferred AT&T Shares determined by dividing such
      amount by the price of AT&T common shares, as determined in the last
      sentence of this paragraph. The price of AT&T common shares related to any
      compensation or dividend payment date shall be the average of the daily
      high and low sale prices of AT&T common shares on the New York Stock
      Exchange ("NYSE") for the period of five trading days immediately
      preceding such date, or the period of five trading days immediately
      preceding such date, if the NYSE is closed on such date.

            In the event of any change in outstanding AT&T common shares by
      reason of any stock dividend, split, reverse split, recapitalization,
      merger, consolidation, combination or exchange of shares or other similar
      corporate change, the AT&T Board of Directors shall make such adjustments,
      if any, that it deems appropriate in the number of deferred AT&T Shares
      then credited to Director's accounts. Any and all such adjustments shall
      be conclusive and binding upon all parties concerned.

            The maximum number of deferred AT&T Shares that may be maintained in
      the AT&T Shares portion of all Directors' deferred compensation account
      may not exceed one million (1,000,000). This number is subject to
      adjustment to take into consideration adjustment in the number of
      outstanding AT&T common shares as described in the preceding paragraph.

            (c) Deferred Cash. Deferred amounts credited to the Cash portion of
      a Director's account shall bear interest from the date the related
      compensation is or

                                        3

      would otherwise be paid. The interest credited to the cash portion of the
      account will be compounded quarterly at the end of each calendar quarter.
      For all amounts credited on or after January 1, 2001, the rate of interest
      credited thereon, as of the end of each calendar quarter, shall be equal
      to the average ten-year U. S. Treasury note rate for the previous calendar
      quarter plus 2% or such other rate as shall be determined from time to
      time by the Board of Directors. For all amounts credited prior to January
      1, 2001, the rate of interest credited thereon, as of the end of each
      calendar quarter, shall be equal to the average ten-year U. S. Treasury
      note rate for the previous calendar quarter plus 5%.

4.    Distribution

            (a) At the time of election to participate in the Plan, a Director
      shall also make elections with respect to the distribution (during the
      Director's lifetime or in the event of the Director's death) of amounts
      and shares deferred under the Plan plus accumulated earnings. Such
      elections shall be contained in the document referred to in Item 2 (b),
      executed by the Director and filed with the Secretary of the Company. The
      election with respect to the distribution during the Director's lifetime,
      of fees and shares for any calendar year, shall become irrevocable on the
      last day prior to the beginning of such calendar year. The election
      related to the distribution in the event of the Director's death,
      including the designation of a beneficiary or beneficiaries, may be
      changed by the Director at any time, by filing the appropriate document
      with the Secretary of the Company.

            (b) A Director may elect to receive amounts and shares credited to
      his or her account in one payment or in some other number of approximately
      equal annual installments (not exceeding 20), provided, however, that the
      number of annual installments may not extend beyond the life expectancy of
      the Director, determined as of the date the first installment is paid. The
      election shall direct that the first installment (or the single payment if
      the Director has so elected) be paid on the first day of the calendar year
      immediately following either (1) the year in which the Director ceases to
      be a Director of the Company, or (2) the later of the year in which the
      Director ceases to be a Director of the Company or the year in which the
      Director attains the age specified in such election, which age shall not
      be later than age 70-1/2. Each distribution of shares of AT&T common stock
      resulting from the vesting of restricted stock unit awards shall be made
      from the AT&T Shares portion of the Director's account. Each other
      distribution shall be made pro-rata from amounts credited to the cash
      portion and to the AT&T Shares portion of the Director's account on the
      applicable payment date.

            (c) Each distribution of shares of AT&T common stock resulting from
      the vesting of restricted stock unit awards shall be made in shares of
      AT&T common stock authorized for issuance under AT&T's long term incentive
      plans. All other distributions, including all dividend equivalents, shall
      be in cash. For this purpose, the value of deferred AT&T Shares
      distributed on any payment date

<PAGE>

                                        4

      shall be determined by multiplying the number of such deferred AT&T Shares
      by the price of AT&T common stock, as determined in the following
      sentence. The price of AT&T common shares related to any payment date
      shall be the average of the daily high and low sales prices of AT&T common
      shares on the New York Stock Exchange ("NYSE") for the period of five
      trading days ending on such date, or the period of five trading days
      immediately preceding such date, if the NYSE is closed on such date.

            (d) Notwithstanding an election pursuant to Item 4(b), in the event
      a Director engages in any competitive activity, as determined in
      accordance with and pursuant to the terms and conditions of the AT&T
      Non-Competition Guideline, or becomes employed by any governmental agency
      having jurisdiction over the activities of the Company or any of it
      subsidiaries, the entire balance in the Director's deferred account,
      including earnings, shall be paid immediately in a single payment and
      distribution of shares.

            (e) A Director may elect that, in the event the Director should die
      before full payment of all amounts credited to the Director's deferred
      account, the balance of the deferred amounts shall be distributed in one
      payment or in some other number of approximately equal annual installments
      (not exceeding 10) to the beneficiary or beneficiaries designated in
      writing by the Director, or if no designation has been made, to the estate
      of the Director. The first installment (or the single payment if the
      Director has so elected) shall be paid on the first day of the calendar
      year following the year of death.

            (f) Installments subsequent to the first installment to the
      Director, or to a beneficiary or to the Director's estate, shall be paid
      on the first day of each succeeding calendar year until the entire amount
      credited to the Director's deferred account shall have been paid. Deferred
      amounts held pending distribution shall continue to be credited with
      earnings, determined in accordance with Item 3.

5.    Miscellaneous

            (a) The right of a Director to any deferred fees, shares and/or
      earnings thereon shall not be subject to assignment by the Director.

            (b) All deferred amounts shall be held in the general funds of the
      Company. The Company shall not be required to reserve, or otherwise set
      aside, funds for the payment of its obligation hereunder.

            (c) Copies of the Plan and any and all amendments thereto shall be
      made available at all reasonable times at the office of the Secretary of
      the Company to all Directors.
