      4.1 Election to Commence a Savings Unit. Any Eligible Employee may elect

      Agreement, the Eligible Employee shall elect the percentage of Base

      percentage shall remain in effect for the duration of the Unit Period even
      if Base Compensation should change. Such Agreement shall continue to be
      regarded as, and shall apply as, the Eligible Employee's election to
      commence each successive Savings Unit until the Company is advised in
      writing in accordance with the aforesaid time requirements by the Eligible
      Employee to the contrary. In the Agreement, the Participant shall also
      elect either the Retirement Alternative or the Specified Date Alternative
      and the timing of distribution of Stock.

      The Participant's percentage of Base Compensation applicable to a Savings
      Unit shall be a whole percentage and must be at least six percent (6%) and
      not more than thirty percent (30%).






      A Participant shall be permitted to contribute all or a portion of his
      Short Term Incentive Award as follows. A Participant's election to
      contribute all or a portion of his Short Term Incentive Award which may be
      paid to a Participant by an Employer, shall be filed with the Company (on
      a form to be provided by the Company for such purpose) prior to the
      beginning of the calendar year during which such Award is earned (for
      Savings Units with Unit Start Date of January 1, 1998, or later, and for
      PTGSTIP payments that constitute Short Term Incentive Awards, the election
      must be filed prior to the beginning of the calendar year during which
      such Award is paid), or such earlier time as may be established by the
      Chairman. The contribution shall be deemed to have taken place on the day
      the Award would otherwise have been paid. In the Agreement relating to the
      Award, the Participant shall also elect either the Retirement Alternative
      or the Specified Date Alternative and the timing of distribution of Stock.
      This election is independent of the election for distribution of
      contributions associated with deferrals of Base Compensation. Such
      contribution of all or a portion of Participant's Short Term Incentive
      Award shall comprise a separate Savings Unit. Notwithstanding the
      foregoing, Short Term Incentive Awards or any portion thereof contributed
      to the Plan prior to January 1, 1995, shall be credited into a 1994 or
      prior Savings Unit(s) as specified by the Participant.

      4.2 Termination of Election. A Participant's election to participate in
      the Plan for the duration of the Unit Period is irrevocable upon the
      filing of his Agreement with the Company; provided, however, such election
      may be terminated with respect to Base Compensation not yet paid by mutual
      agreement in writing between the Participant and the Company. Such
      termination if approved shall be effective beginning the first day of the
      month following the execution of such mutual agreement.


Section 5 - Pre-Tax Contributions/After-Tax Contributions/Company Match

      5.1 After-Tax and/or Pre-Tax Account(s). The Company shall establish and
      maintain a separate After-Tax Account (for contributions pursuant to
      Savings Units commenced prior to January 1, 1995 only) and/or Pre-Tax
      Account for each Participant for each Savings Unit. On the first business
      day of each month, the Company shall credit each Participant's Pre-Tax
      Account with the number of Shares found by dividing the Participant's
      Pre-Tax Amount for the previous month by the FMV on the last day of such
      previous month. Annual base salary shall be deemed contributed when
      earned; all other amounts shall be deemed contributed when paid.

      Shares credited to Participant's Pre-Tax Account and/or After-Tax Account
      are 100% vested at all times.

      Such Pre-Tax Account and/or After-Tax Account, as applicable, shall be
      reduced by the number of Shares corresponding to the number of shares of
      Stock distributed by the Company to the Participant or the Participant's
      Beneficiary with respect to such Savings Unit pursuant to this Plan.






      5.2 Company Matching Account. The Company shall also establish and
      maintain a separate Matching Account for each Participant. The Matching
      Account will hold the Company's matching contribution to the Plan.
      Immediately following the computation of the Shares to be added to each
      Participant's Pre-Tax Account each month, the Company shall credit each
      Participant's Matching Account with the number of Shares found by taking
      the Company Match Rate Expressed as a Percent times the Participant's
      Pre-Tax Amount for the previous month, and dividing the resulting figure
      by the FMV of the Stock on the last day of such previous month; provided,
      however, if the Participant is concurrently participating in this Plan and
      (a) the match eligible (basic) portion of the SBC Savings Plan or (b) the
      match eligible portion of any other qualified plan of Employer, the
      matching contribution shall be credited, pursuant to this Plan, with
      respect to no more than six percent (6%) of the Participant's monthly Base
      Compensation less the basic (match eligible) election percentage in such
      plan; and provided further, however, Company matching contributions shall
      be paid, pursuant to this Plan and all plans of Employer combined, with
      respect to no more than six percent (6%) of Participant's monthly Base
      Compensation. Company Match shall only be paid on Base Compensation.

      5.3 Dividends. Additional Shares shall be credited to each Participant's
      Pre-Tax Account, After-Tax Account, and Matching Account, respectively,
      for dividends on Stock, on the basis of the number of Shares credited to
      each such Account on the record date for such dividend.

      The number of additional Shares to be credited to each Account for any
      dividend payment date shall be determined by dividing the total dividends
      which would have otherwise been payable on the number of Shares recorded
      in each Account, by the FMV on the last day of the month containing the
      dividend record date. The additional Shares shall be credited to each
      Account, as appropriate, on the last day of the month containing the
      dividend record date.

      5.4 Vesting of Matching Account. A Participant's interest in his Matching
      Account shall vest at such time as Participant shall have five (5) years
      of service as reflected on the records of Employer; provided, however, the
      Matching Account of any Participant who was employed by Employer on
      December 31, 1988 shall be 100% vested at all times. Shares in the
      Matching Account relating to a Savings Unit shall not be available for
      distribution to the Participant until vested and: (i) for ten (10) years
      after the Unit Period for such Savings Unit has ended and until the
      Participant is at least fifty-five (55) years of age, or (ii) until
      Participant's Retirement or other termination of employment (including
      death). Upon termination of employment, all unvested Shares shall be
      forfeited.

      5.5 Statement of Accounts. Each Participant will receive annual statements
      in such form as the Company deems desirable setting forth the balance of
      Shares standing to the credit of each of the Participant's Pre-Tax,
      After-Tax and Matching Accounts.



Section 6 - Retirement Alternative

      Section 6 shall apply to the portions of all Savings Units for which the
      Retirement Alternative is elected. (Section 7 shall have no application to
      such portions of such Savings Units.) The distributions specified in this
      Section 6 shall be provided under the Retirement Alternative.






      6.1 Retirement Distribution. Upon Retirement or, effective for Savings
      Units commenced on or after January 1, 1995, the calendar year following
      Retirement if so elected by the Participant, with respect to a Savings
      Unit, the Company shall distribute to the Participant each year for up to
      fifteen (15) years, the number of years to be selected by Participant in
      his Agreement, beginning on the first day of the month next following the
      date of Retirement or during February of the year following Retirement if
      the calendar year following Retirement is elected for commencing
      distribution of Savings Units commenced on or after January 1, 1995, and
      annually on such date thereafter, from Participant's Pre-Tax Account,
      After-Tax Account, and Matching Account, shares of Stock corresponding to
      the number of Shares in each such Account on such date divided by the
      number of distributions to be made immediately prior to each such
      distribution. During the payout period, each such Account shall be
      credited with dividends in accordance with Section 5.3.

      The Participant shall elect the number of years of distribution of a
      Retirement Distribution no later than the end of the calendar year
      immediately preceding the first distribution. If a Participant's Agreement
      fails to show an election as to the number of years of distribution of a
      Retirement Distribution, and an election is not made no later than the end
      of the calendar year immediately preceding the first distribution, such
      Participant will receive distribution in two annual installments beginning
      on the first of the month next following the date of Retirement or during
      February of the year following Retirement, whichever commencement date was
      previously elected by the Participant.

      In the event that a final determination shall be made by the Internal
      Revenue Service or any court of competent jurisdiction that, by reason of
      Retirement, a Participant has recognized gross income for Federal income
      tax purposes in excess of the Retirement Distribution installment actually
      distributed by the Company to which such gross income is attributable, the
      Company shall make a lump sum distribution to the Participant of shares of
      Stock corresponding to the remaining Shares of his Pre-Tax, After-Tax and
      Matching Accounts for any affected Savings Units. If a distribution is
      made to a Participant pursuant to this paragraph for any Savings Unit, no
      other distributions shall thereafter be made under this Plan with respect
      to such Savings Unit.

      Notwithstanding any election made by the Participant, the Company will
      distribute the Participant's Retirement Distribution in the form of a lump
      sum distribution if the FMV of his Pre-Tax plus After-Tax plus Matching
      Accounts for a Savings Unit is less than $10,000 when distribution of the
      Retirement Distribution for such Savings Unit would otherwise commence.

      6.2  Termination Distribution.

      6.2(a) Termination of Employment Before Retirement. Upon any termination
      of employment of the Participant for reasons other than death or
      Disability or Retirement, the Company shall distribute to the Participant,
      with respect to a Savings Unit, in a lump sum, shares of Stock
      corresponding to the vested portion of the Shares standing credited to his
      Pre-Tax, After-Tax and Matching Accounts for such Savings Unit determined
      as of the date of such termination of service ("Termination
      Distribution").






      6.2(b) Termination of a Savings Unit. A Participant shall terminate a
      Savings Unit if he terminates his election to participate in the Plan with
      respect to a Savings Unit pursuant to Section 4.2. Notwithstanding any
      other provision of the Plan, upon such discontinuance, the Participant
      shall immediately cease to be eligible for any distribution other than his
      Termination Distribution with respect to that Savings Unit (which shall be
      distributed upon his severance of employment) except as provided under
      Section 11.1. The Participant shall continue to be credited with dividends
      on the Shares standing credited to his Pre-Tax, After-Tax and Matching
      Accounts as provided under Section 5.3 and to vest in Shares as provided
      under Section 5.4 while he remains in employment with the Employer until
      payment of his Termination Distribution. However, no further Participant
      pre-tax or after-tax or Company contributions to this Plan shall be made
      pursuant to Sections 5.1 or 5.2 with respect to a Savings Unit after a
      Participant terminates such Savings Unit.

      6.2(c) Loss of Eligibility. In the event that the Participant ceases to be
      an Eligible Employee by reason of a change to an employment status which
      is not eligible to participate in this Plan, the Participant shall
      nevertheless continue participation in this Plan while he remains in
      employment with Employer; however, no further Participant pre-tax
      contributions or after-tax contributions, or Company matching
      contributions shall be made to this Plan pursuant to Sections 5.1 or 5.2
      subsequent to the date of such loss of eligibility.

      6.3 Disability. In the event that a Participant suffers a Disability,
      pre-tax contributions and/or after-tax contributions and Company matching
      contributions that otherwise would have been credited to Participant's
      Pre-Tax Account, After-Tax and Matching Accounts, as applicable, in
      accordance with Sections 5.1 and 5.2 will continue to be credited to such
      Accounts out of his disability payments (as used in this Plan, disability
      payments and disability benefits shall refer to only to Employer payments)
      at the same time and in the same amounts as they would have been credited
      if the Participant had not suffered a Disability for as long as he is
      eligible to receive monthly disability benefits equal to 100 percent of
      his monthly base salary at the time of his Disability. At such time as the
      Participant is not eligible to receive monthly disability benefits equal
      to 100 percent of his monthly Base Compensation at the time of his
      Disability, Participant pre-tax contributions and/or after-tax
      contributions and Company matching contributions that otherwise would have
      been credited to the Accounts of the Participant in accordance with
      Section 5.1 and 5.2 shall cease.

      If the Participant recovers from his Disability and returns within sixty
      (60) days thereafter to employment with Employer in an employment status
      which would make him eligible to participate in this Plan and prior to the
      end of the original Unit Period, the Participant shall continue or resume
      making pre-tax contributions and/or after-tax contributions, as the case
      may be, in accordance with Section 5.1 and the Company shall continue or
      resume making matching contributions, as the case may be, in accordance
      with Section 5.2 until the end of the original Unit Period.






      If the Participant recovers from his Disability, the Participant shall be
      treated as terminating service with Employer on the date of his recovery,
      unless within sixty (60) days thereafter he returns to employment with
      Employer in an employment status which makes him eligible to participate
      in this Plan.

      If a Participant's Disability terminates by reason of his death, the
      rights of his Beneficiary shall be determined pursuant to Section 6.4 as
      if the Participant had not been disabled but rather had been in service on
      the date of his death and died on such date. If a Participant's Disability
      terminates by reason of attainment of age 65, the Participant shall upon
      the attainment of age 65 be entitled to a Retirement Distribution
      determined pursuant to Section 6.1. If a Participant's Disability
      terminates by reason of Retirement, the Participant shall be treated as
      having a Retirement on the date elected by the Participant and shall be
      entitled to a Retirement Distribution determined pursuant to Section 6.1.

      6.4  Survivor Distribution.

      6.4(a) If a Participant dies while in service with Employer (or while
      suffering from a Disability) prior to eligibility for Retirement with
      respect to a Savings Unit, upon the Participant's death the Company will
      distribute to the Participant's Beneficiary with respect to such Savings
      Unit, shares of Stock corresponding to all of the Shares in Participant's
      Pre-Tax, After-Tax and Matching Accounts. Distribution shall occur in the
      month following the date of death.

      6.4(b) If a Participant dies while in service after eligibility for
      Retirement with respect to a Savings Unit, but prior to commencement of
      distribution of a Retirement Distribution with respect to such Savings
      Unit, the Company will distribute to the Participant's Beneficiary the
      Stock that such Participant's Beneficiary would have received with respect
      to such Savings Unit had the Participant retired and commenced to receive
      a Retirement Distribution on the day prior to such Participant's death.
      Such distributions shall be made in accordance with the number of
      installments which the Participant had elected for distribution of his
      Retirement Distribution.

      6.4(c) If a Participant dies after Retirement but before commencement of
      distribution of a Retirement Distribution with respect to a Savings Unit,
      the Company will distribute to the Participant's Beneficiary the
      installments that Participant would have received with respect to such
      Savings Unit had the Participant survived. Payments will commence
      effective with the Participant's death. Such distributions shall be made
      in accordance with the method of distribution which the Participant had
      elected for distribution of his Retirement Distribution.

      6.4(d) If a Participant dies after the commencement of payment of a
      Retirement Distribution with respect to a Savings Unit, the Company will
      distribute to the Participant's Beneficiary the remaining installments
      that would have been distributed to the Participant had the Participant
      survived.







Section 7 - Specified Date Alternative

      Section 7 shall apply to the portions of all Savings Units for which the
      Specified Date Alternative is elected. (Section 6 shall have no
      application to such portions of such Savings Units.) The distributions
      specified in this Section 7 shall be provided under the Specified Date
      Alternative.

      7.1 Specified Date Distribution. If a Participant elects the Specified
      Date Alternative with respect to a Savings Unit, the Company shall
      distribute to the Participant each year for up to four (4) years, the
      number of years to be selected by Participant in his Agreement, beginning
      on the first day of the month selected in his Agreement for commencement
      of distributions, and annually on such date thereafter, from Participant's
      Pre-Tax Account, After-Tax Account, and Matching Account (to the extent
      available for distribution), shares of Stock corresponding to the number
      of Shares in each such Account on such date divided by the number of
      distributions to be made immediately prior to each such distribution.
      During the payout period, each such Account shall be credited with
      dividends in accordance with Section 5.3. Shares of Stock corresponding to
      Shares in the Matching Account which are not immediately available for
      distribution shall be distributed to the Participant in a lump sum
      distribution as soon as practicable after such Shares become available for
      distribution. While such Shares remain in the Matching Account, such
      Account shall be credited with dividends on such Shares in accordance with
      Section 5.3.

      A Participant may elect, as the Specified Date for a Savings Unit, the
      first day of any month after the January following the calendar year
      during which the Savings Unit commences. If the Participant elects an
      annual distribution, the Savings Unit shall be paid out in February
      following the end of the Unit Period or as soon thereafter as is
      practicable.

      Notwithstanding any election made by the Participant, the Company will
      distribute the Participant's Specified Date Distribution in the form of a
      lump sum distribution if the FMV of his Pre-Tax plus After-Tax plus
      Matching Accounts for a Savings Unit is less than $10,000 when
      distribution of a Specified Date Distribution for such Savings Unit would
      otherwise commence.


      7.2  Termination Distribution.

      7.2(a) Termination of Employment Prior to Specified Date. Upon any
      termination of employment of the Participant for reasons other than death
      or Disability or Retirement before the Specified Date selected for a
      Savings Unit, the Company shall distribute to the Participant, with
      respect to such Savings Unit, in a lump sum, shares of Stock corresponding
      to the vested portion of the Shares standing credited to his Pre-Tax,
      After-Tax and Matching Accounts for such Savings Unit determined as of the
      date of such termination of service ("Termination Distribution").






      7.2(b) Termination of a Savings Unit. The provisions of Section 6.2(b)
      shall apply with respect to the termination of any Savings Unit for which
      the Specified Date Alternative is selected.

      7.2(c) Loss of Eligibility. The provisions of Section 6.2(c) shall apply
      with respect to the loss of eligibility under any Savings Unit for which
      the Specified Date Alternative is selected.

      7.3 Disability. In the event that a Participant suffers a Disability, the
      provisions of Section 6.3 shall apply except that the provisions of the
      following paragraphs shall govern.

      If a Participant's Disability terminates by reason of his death prior to
      the Specified Date, the rights of his Beneficiary shall be determined
      pursuant to Section 7.4 as if the Participant had not been disabled but
      rather had been in service on the date of his death and died on such date.

      If a Participant suffering from a Disability attains the Specified Date
      for a Savings Unit, the Participant shall be entitled to the Specified
      Date Distribution determined pursuant to Section 7.1.

      7.4  Survivor Distribution.

      7.4(a) If a Participant dies prior to the commencement of distribution of
      the Specified Date Distribution with respect to a Savings Unit, upon the
      Participant's death the Company will distribute to the Participant's
      Beneficiary with respect to such Savings Unit, shares of Stock
      corresponding to all of the Shares in Participant's Pre-Tax, After-Tax and
      Matching Accounts. Distribution shall occur in the month following the
      date of death.

      7.4(b) If a Participant dies after the commencement of payment of an
      Specified Date Distribution with respect to a Savings Unit, the Company
      will distribute to the Participant's Beneficiary the remaining
      installments of any such distribution that would have been distributed to
      the Participant had the Participant survived.


Section 8 - Beneficiary Designation






      Each Participant shall have the right, at any time, to designate pursuant
      to the SBC Rules for Employee Beneficiary Designations as may hereafter be
      amended from time to time ("Rules"), which Rules shall apply hereunder and
      are incorporated herein by this Reference, any person or persons as his
      Beneficiary or Beneficiaries (both primary as well as contingent) to whom
      distributions of Stock under this Plan shall be made in the event of his
      death prior to complete distribution to Participant of the distributions
      due him under the Plan. Each Beneficiary designation shall become
      effective only when filed in writing with the Company during the
      Participant's lifetime on a form prescribed by the Company with written
      acknowledgment of receipt.

      The filing of a new Beneficiary designation form will cancel all
      Beneficiary designations previously filed. The spouse of a married
      Participant domiciled in a community property jurisdiction shall join in
      any designation of Beneficiary or Beneficiaries other than the spouse.

      If a Participant fails to designate a Beneficiary as provided above, or if
      all designated Beneficiaries predecease the Participant or die prior to
      complete distribution of the Participant's distributions, then the Company
      shall direct the distribution of such distributions according to the
      Rules.


Section 9 - Options

      9.1 Grants. The HRC shall determine at its discretion whether the Options
      issued pursuant to this Plan shall be non-qualified stock Options or
      incentive stock Options within the meaning of Section 422 of the Code. Any
      Options issued hereunder shall be non-qualified Options unless the HRC
      specifies prior to the Unit Start Date that they shall be incentive stock
      Options. Notwithstanding any other provision of the Plan, any incentive
      stock Options issued under this Plan shall be issued and exercised in
      accordance with Section 422 of the Code. The Options may be issued in
      definitive form or recorded on the books and records of the Company for
      the account of the Participant, at the discretion of the Company. If the
      Company elects not to issue the Options in definitive form, they shall be
      deemed issued, and the Participants shall have all rights incident thereto
      as if they were issued on the dates provided herein, without further
      action on the part of the Company or the Participant. In addition to the
      terms herein, all Options shall be subject to such additional provisions
      and limitations as provided in any Administrative Procedures adopted by
      the HRC prior to the issuance of such Options. The number of Options
      issued to a Participant shall be reflected on the Participant's annual
      statement of account.

      9.2 Term of Options. The Options may only be exercised: (a) after the
      earlier of (i) the expiration of one year from date of issue or (ii) the
      Participant's termination of employment (only for Options issued on or
      after August 1, 1998), and (b) no later than the tenth anniversary of
      their issue, and shall be subject to earlier termination as provided
      herein.

      9.3  Exercise Price.  The price per share of Stock  purchasable  under an
      Option  shall  be the  Fair  Market  Value  of the  Stock  on the date of
      issuance of the Options.






      9.4 Issuance of Options. February 1 and August 1 of each year shall each
      be an Option issuance date, unless Stock is not traded on the NYSE on such
      day in which event the immediate following day in which Stock is so traded
      shall be the Option issuance date. On each Option issuance date, each
      Participant shall receive two Options, or such higher number as may be
      determined by the HRC, in its sole discretion, at any time, or such lower
      number as may be determined by the HRC, in its sole discretion, and
      announced to Participants prior to the Unit Start Date with respect to a
      Savings Unit, for each Share credited to the Participant's Pre-Tax Account
      during the preceding six month periods. The number of Options to be
      received shall be determined by multiplying the number of Shares by the
      number of Options to be received for each Share and rounding up to the
      next whole number; provided, however, that no more than 200,000 Options
      shall be issued to any individual during the calendar year. No Share may
      be counted more than once for the issuance of Options and Options shall
      only be issued for Shares credited to a Savings Unit with respect to its
      Unit Period.

      In addition to the foregoing, the HRC may, at any time and in any manner,
      limit the number of Options which may be acquired as a result of the Short
      Term Incentive Award being contributed to the Plan. Further, except as
      otherwise provided by the HRC, in determining the number of Options to be
      issued to a Participant with respect to a Participant's contribution of a
      Short Term Incentive Award to the Plan and subsequent crediting of Shares,
      Options may be issued only with respect to an amount which does not exceed
      the target amount of such award (or such other portion of the award as may
      be determined by the HRC).

      Accordingly, the following rules shall apply:

           Options To Be Issued With Respect To A Short Term  Incentive  Award
           Contributed To The Plan.

           A Participant shall be permitted to contribute his Short Term
           Incentive Award, although paid after Retirement, into the Stock
           Savings Plan; and, subject to application of the rule in the
           following sub paragraph, Options may be issued thereon and on the
           dividends that would accumulate thereon applicable to the calendar
           year when the Short Term Award was placed into the Plan.

           Participants  Who  Retire,  Terminate  Employment  Or  Terminate  A
           Savings Unit.






           Options are calculated on August 1 and February 1, in each case for
           the preceding six month periods based on the Shares posted to the
           Participant's accounts. The August 1 options are for January through
           June contributions plus 1st quarter and 2nd quarter dividend
           equivalents. The February 1 options are for July through December
           contributions plus the 3rd quarter and 4th quarter dividend
           equivalents. If a Participant retires, terminates employment or
           terminates a Savings Unit during an ongoing savings period, since the
           Unit Period ends upon Retirement, termination, etc., a dividend
           equivalent shall be treated as being paid with respect to a Unit
           Period (i.e., for purposes of receiving Options on such dividend
           equivalent) only if the Participant is employed on any day of the
           last month of the quarter preceding payment of the dividend, e.g.,
           one must be employed at least one day in December in order to receive
           Options on the fourth quarter dividend equivalent paid the following
           February 1. A retiree shall thus receive Options on dividends issued
           with respect to his/her last quarter if he or she worked at any time
           during the last month of such quarter. The same shall apply if a
           Savings Unit is terminated. However, if a Participant terminates
           employment other than as a result of Retirement or for any reason
           other than death or Disability, no further options shall be issued to
           the Participant on or after the last day of employment.

      9.5 Exercise and Payment of Options. Options shall be exercised by
      providing notice to the designated agent selected by the Company (if no
      such agent has been designated, then to the Company), in the manner and
      form determined by the Company, which notice shall be irrevocable, setting
      forth the exact number of shares of Stock with respect to which the Option
      is being exercised and including with such notice payment of the Exercise
      Price. When Options have been transferred, the Company or its designated
      agent may require appropriate documentation that the person or persons
      exercising the Option, if other than the Participant, has the right to
      exercise the Option. No Option may be exercised with respect to a fraction
      of a share of Stock.

      The Exercise Price shall be paid in full at the time of exercise. No Stock
      shall be issued or transferred until full payment has been received
      therefor.

      Payment may be made:

      (a) in cash, or

      (b) unless otherwise provided by the Committee at any time, and subject to
      such additional terms and conditions and/or modifications as the Committee
      or the Company may impose from time to time, and further subject to
      suspension or termination of this provision by the Committee or the
      Company at any time, by:

           (i) delivery of Stock owned by the Participant in partial (if in
           partial payment, then together with cash) or full payment; provided,
           however, as a condition to paying any part of the Exercise Price in
           Stock, at the time of exercise of the Option, the Participant must
           establish to the satisfaction of the Company that the Stock tendered
           to the Company must have been held by the Participant for a minimum
           of six (6) months preceding the tender; or






           (ii) if the Company has designated a stockbroker to act as the
           Company's agent to process Option exercises, issuance of an exercise
           notice to such stockbroker together with instructions irrevocably
           instructing the stockbroker: (A) to immediately sell (which shall
           include an exercise notice that becomes effective upon execution of a
           limit order) a sufficient portion of the Stock to pay the Exercise
           Price of the Options being exercised and the required tax
           withholding, and (B) to deliver on the settlement date the portion of
           the proceeds of the sale equal to the Exercise Price and tax
           withholding to the Company. In the event the stockbroker sells any
           Stock on behalf of a Participant, the stockbroker shall be acting
           solely as the agent of the Participant, and the Company disclaims any
           responsibility for the actions of the stockbroker in making any such
           sales. No Stock shall be issued until the settlement date and until
           the proceeds (equal to the Exercise Price and tax withholding) are
           paid to the Company.

      If payment is made by the delivery of Stock, the value of the Stock
      delivered shall be equal to the Fair Market Value of the Stock on the day
      preceding the date of exercise of the Option.

      Restricted Stock may not be used to pay the Option exercise price.

      9.6 Restrictions on Exercise and Transfer. During the optionee's lifetime
      (for purposes of Paragraphs 9.6 through 9.9, "optionee" shall only refer
      to the original recipient of an Option), the optionee's Options shall be
      exercisable only by the optionee or by the optionee's guardian or legal
      representative. After the death of the optionee, except as otherwise
      provided by the Company's Rules for Employee Beneficiary Designations, an
      Option shall only be exercised by the holder thereof (including, but not
      limited to, an executor or administrator of a decedent's estate) or his or
      her guardian or legal representative.

      No Option shall be transferable except: (a) upon the death of the optionee
      in accordance with the Company's Rules for Employee Beneficiary
      Designations; and (b) in the case of any holder after the optionee's
      death, only by will or by the laws of descent and distribution.

      9.7 Termination by Death. If an optionee's employment with Employer
      terminates by reason of death, the Option may thereafter be exercised, to
      the extent then exercisable, for a period of three (3) years from the date
      of such death or until the expiration of the stated term of such Option,
      whichever period is shorter.

      9.8 Termination by Disability. If an optionee's employment with Employer
      terminates by reason of Disability, any Option held by such optionee may
      thereafter be exercised, to the extent it was exercisable at the time of
      such termination (or on such accelerated basis as the HRC shall determine
      at the time of grant), for a period of three (3) years from the date of
      such termination of employment or the expiration of the stated term of
      such Option, whichever period is shorter.






      9.9 Retirement or Other Termination of Employment. Except as otherwise
      provided in this paragraph, if an optionee's employment with Employer
      terminates as a result of Retirement or for any reason other than death or
      Disability, the Option may be exercised until the earlier of three months
      (one year for options granted on or after August 1, 1998) from the date of
      termination or three years (five years for options granted on or after
      August 1, 1998) from the date of Retirement, as applicable, or the
      expiration of the term of such Option; provided, however, that a transfer
      to a RWAC shall not be considered a termination of employment to the
      extent the term of employment at a RWAC is equal to or less than five
      years.


Section 10 - Discontinuation, Termination, Amendment

      10.1 Company's Right to Discontinue Offering Savings Units. The HRC or the
      Chairman may at any time discontinue offerings of additional Savings Units
      with respect to any or all future Plan Years. Any such discontinuance
      shall have no effect upon the pre-tax contributions or after-tax
      contributions or the terms or provisions of this Plan as applicable to any
      then previously existing Savings Units.

      10.2 Company's Right to Terminate Plan. No Savings Unit may be commenced
      after December 31, 2004. The HRC may terminate the Plan at any earlier
      time. Termination of the Plan shall mean that (1) there shall be no
      further offerings of additional Savings Units with respect to any future
      Plan Year; (2) pre-tax contributions and after-tax contributions shall
      prospectively cease with respect to all Savings Units for the then Plan
      Year and thereafter; and (3) all then currently existing Savings Units
      shall be treated as follows:

           The Participant's Matching Accounts shall be 100% vested. The
           Participant shall receive or continue to receive all distributions
           under this Plan at such time as provided in and pursuant to the terms
           and conditions of his Agreement(s) and as described in this Plan;
           provided, however, any distributions under a Savings Unit that is not
           completed due to a termination of the Plan under this Section 10.2
           shall be based upon only the actual pre-tax contributions plus
           after-tax contributions plus Company contributions made with respect
           to such Savings Unit prior to such termination, and dividends on same
           thereafter.






      10.3 Amendment. The HRC may at any time amend the Plan in whole or in part
      including, but not limited to, changing the formulas for determining the
      amount of Company contributions under Section 5 or the number of Options
      to be issued under Section 9; provided, however, that no amendment,
      including an amendment to this Section 10, shall be effective, without the
      written consent of a Participant, to alter, to the detriment of such
      Participant, the distributions described in this Plan as applicable to a
      Savings Unit of the Participant or to decrease the number of Shares
      standing credited to such Participant's Pre-Tax, After-Tax and Matching
      Accounts under the Plan. For purposes of this Section 10.3, an alteration
      to the detriment of a Participant shall mean a reduction in the period of
      time over which stock is distributable under a Participant's Agreement, or
      any reduction in the number of Options, increase in Exercise Price or
      decrease in the term of an Option. Written notice of any amendment shall
      be given to each Participant.

      Notwithstanding anything to the contrary contained in this section of the
      Plan, the HRC may modify this Plan with respect to any person subject to
      the provisions of Section 16 of the Securities Exchange Act of 1934 as
      amended ("Exchange Act") to place additional restrictions on the exercise
      of any Option or the transfer of any Stock not yet issued under the Plan.

Section 11 - Miscellaneous.

      11.1 Additional Benefit. The reduction of any benefit payable under the
      SBC Pension Benefit Plan (or comparable plan identified by the Company as
      a replacement therefore), which results from participation in this Plan,
      will be restored as an additional benefit ("make-up piece") under this
      Plan. The Participant shall elect prior to commencement of payment of the
      make-up piece whether to receive such benefit in cash in a lump sum
      (consisting of the present value equivalent of the pension retirement
      benefit (life annuity) make-up piece) or such benefit in an annuity form
      of payment. Notwithstanding the proceeding provisions of this Section
      11.1, if all or a portion of the make-up piece is paid pursuant to SRIP or
      another non-qualified plan, then such amount shall not be payable pursuant
      to this Plan.

      11.2 Small Distribution. Notwithstanding any election made by the
      Participant, the Company will distribute any shares of Stock corresponding
      to Shares in the form of a lump sum distribution if the Shares in
      Participant's Pre-Tax Account plus After-Tax Account plus Matching Account
      have a FMV of less than $10,000 when such distribution would otherwise
      commence.

      11.3 Emergency Distribution. In the event that the HRC, upon written
      petition of the Participant, determines in its sole discretion, that the
      Participant has suffered an unforeseeable financial emergency, the Company
      shall distribute to the Participant, as soon as practicable following such
      determination, Stock corresponding to the number of Shares ordered by the
      HRC from his Pre-Tax, After-Tax and Matching Accounts for one or more
      Savings Units as necessary to meet the emergency (the "Emergency
      Distribution"). For purposes of this Plan, an unforeseeable financial
      emergency is an unexpected need for cash arising from an illness, casualty
      loss, sudden financial reversal, or other such unforeseeable occurrence.
      Cash needs arising from foreseeable events such as the purchase of a house
      or education expenses for children shall not be considered to be the
      result of an unforeseeable financial emergency. Upon receipt of an
      Emergency Benefit, a Participant shall not be permitted to commence a new
      Savings Unit until the next enrollment after one whole year has elapsed.






      11.4 Commencement of Payments. Except as otherwise provided in this Plan,
      commencement of a distribution under this Plan shall begin sixty (60) days
      following the event which entitles a Participant (or a Beneficiary) to
      such distribution, or at such earlier date as may be determined by the
      HRC.

      11.5 Tax Withholding. Upon distribution of Stock, including but not
      limited to, shares of Stock issued upon the exercise of an Option, the
      Company shall withhold sufficient shares of Stock having a Fair Market
      Value on the date the taxes are determined necessary to satisfy the
      minimum amount of Federal, state, and local taxes required by law to be
      withheld as a result of such distribution.

      Any fractional share of Stock payable to a Participant shall be withheld
      as additional Federal withholding, or, at the option of the Company, paid
      in cash to the Participant.

      Unless otherwise determined by the Committee, when the method of payment
      for the Exercise Price is from the sale by a stockbroker pursuant to
      Section 9.5(b)(ii), hereof, of the Stock acquired through the Option
      exercise, then the tax withholding shall be satisfied out of the proceeds.
      For administrative purposes in determining the amount of taxes due, the
      sale price of such Stock shall be deemed to be the Fair Market Value of
      the Stock.

      11.6 Reserved

      11.7 Transfer to a RWAC. If a Participant transfers to a RWAC, all of the
      Participant's Savings Units shall be frozen upon transfer, unless
      otherwise determined by the Company. No further Participant pre-tax
      contributions, after-tax contributions or Company contributions shall be
      made subsequent to the transfer. During the period of employment at a RWAC
      (for a period not to exceed five (5) years), the Participant shall
      continue to be credited with dividends on his Pre-Tax, After-Tax and
      Matching Accounts, as applicable, as provided under Section 5.3 and to
      vest in such amounts as provided under Section 5.4, and all distributions
      shall continue to be payable to the Participant and his Beneficiaries in
      accordance with Section 6 and/or Section 7 hereof, as applicable. If the
      Participant has not resumed employment with Employer in an employment
      status which makes him eligible to participate in this Plan within five
      (5) years from the date of transfer, a Termination Distribution based on
      the amounts credited to the Participant's Pre-Tax, After-Tax and Matching
      Accounts, as applicable, shall be paid upon termination of employment with
      a RWAC or the expiration of such five (5) year period, whichever is
      earlier.






      11.8 Leave of Absence. If a Participant absents himself from employment on
      a formally granted leave of absence (i.e., the absence is with formal
      permission in order to prevent a break in the continuity of the Employee's
      term of employment, which permission is granted in conformity with the
      rules of the Employer which employs the individual, as adopted from time
      to time), all of the Participant's Savings Units shall automatically be
      frozen upon such leave of absence, unless otherwise determined by the HRC.
      No Participant pre-tax contributions or after-tax contributions or Company
      contributions shall be made during the leave of absence. However, during
      the leave of absence, the Participant shall continue to be credited with
      dividends on his Pre-Tax, After-Tax and Matching Accounts, as applicable,
      as provided under Section 5.3 and to vest in such amounts as provided
      under Section 5.4, and all distributions shall continue to be payable to
      the Participant and his Beneficiaries in accordance with Section 6 and/or
      Section 7 hereof, as applicable. If the Participant returns to employment
      with Employer in an employment status which makes him eligible to
      participate in this Plan before completion of or immediately upon the
      expiration of the leave of absence, Participant pre-tax contributions and
      Company matching contributions will resume until the end of the original
      Unit Period. If the Participant has not resumed employment with Employer
      in an employment status which makes him eligible to participate in this
      Plan before completion of or immediately upon the expiration of the leave
      of absence, a Termination Distribution based on the amounts credited to
      the Participant's Pre-Tax, After-Tax and Matching Accounts shall be paid
      to the Participant.

      This Section 11.8 shall not apply with respect to any period during which
      a Participant is suffering from a Disability, and such period of
      Disability shall not be included under this Section 11.8 as a portion of a
      period of leave of absence.

      11.9 Ineligible Participant. Notwithstanding any other provisions of this
      Plan to the contrary, if any Participant is determined not to be a
      "management or highly compensated employee" within the meaning of ERISA,
      such Participant will not be eligible to participate in this Plan and
      shall receive an immediate lump sum distribution of shares of Stock
      corresponding to the vested portion of the Shares standing credited to his
      Pre-Tax plus After-Tax plus Matching Accounts. Upon such payment no other
      distribution shall thereafter be payable under this Plan either to the
      Participant or any Beneficiary of the Participant, except as provided
      under Section 11.1.

      11.10 Unsecured General Creditor. Participants and their Beneficiaries,
      heirs, successors, and assigns shall have no legal or equitable rights,
      interest, or claims in any property or assets of Employer. No assets of
      Employer shall be held under any trust for the benefit of Participants,
      their Beneficiaries, heirs, successors, or assigns, or held in any way as
      collateral security for the fulfilling of the obligations of Employer
      under this Plan. Any and all of the Employer's assets shall be, and
      remain, the general, unpledged, unrestricted assets of Employer. The only
      obligation of Employer under the Plan shall be merely that of an unfunded
      and unsecured promise of the Company to distribute shares of Stock
      corresponding to Shares, and Options, under the Plan in the future.

      11.11 Offset. If a Participant becomes entitled to a distribution of Stock
      under the Plan, the Company may offset against the amount of Stock
      otherwise distributable, any claims to reimbursement for intentional
      wrongdoing by the Participant against the Employer or an affiliate as well
      as any overpayment made under this Plan. Such determination shall be made
      by the Company.






      11.12 Non-Assignability. Neither a Participant nor any other person shall
      have any right to commute, sell, assign, transfer, pledge, anticipate,
      mortgage, or otherwise encumber, transfer, hypothecate or convey in
      advance of actual receipt, shares of Stock corresponding to Shares under
      the Plan, if any, or any part thereof, which are, and all rights to which
      are, expressly declared to be unassignable and non-transferable. No part
      of the Stock distributable shall, prior to actual distribution, be subject
      to seizure or sequestration for the payment of any debts, judgments,
      alimony or separate maintenance owed by a Participant or any other person,
      nor be transferable by operation of law in the event of a Participant's or
      any other person's bankruptcy or insolvency.

      11.13 Employment Not Guaranteed. Nothing contained in this Plan nor any
      action taken hereunder shall be construed as a contract of employment or
      as giving any Employee any right to be retained in the employ of Employer
      or to serve as a director.

      11.14 Gender, Singular and Plural. All pronouns and any variations there
      of shall be deemed to refer to the masculine or feminine, as the identity
      of the person or persons may require. As the context may require, the
      singular may be read as the plural and the plural as the singular.

      11.15 Captions. The captions of the articles, sections, and paragraphs of
      this Plan are for convenience only and shall not control nor affect the
      meaning or construction of any of its provisions.

      11.16 Applicable Law. This Plan shall be governed and construed in
      accordance with the laws of the State of Texas, to the extent not
      preempted by ERISA. Any action seeking to enforce an Employee's or
      Beneficiary's rights under this Plan, including but not limited to the
      terms of any Agreement or Option issued hereunder, may only be brought in
      Bexar County, Texas.

      11.17 Validity. In the event any provision of this Plan is held invalid,
      void, or unenforceable, the same shall not affect, in any respect
      whatsoever, the validity of any other provision of this Plan.

      11.18 Notice. Any notice or filing required or permitted to be given to
      the Company under the Plan shall be sufficient if in writing and hand
      delivered, or sent by registered or certified mail, to the principal
      office of the Company, directed to the attention of the Vice
      President-Human Resources of the Company. Such notice shall be deemed
      given on the date of delivery or, if delivery is made by mail, on the date
      shown on the postmark on the receipt for registration or certification.

      11.19 Successors and Assigns. This Plan shall be binding upon the Company
      and its successors and assigns.






      11.20 Limitations and Adjustments. The number of shares of Stock which may
      be distributed pursuant to the Plan, exclusive of Section 9, is 6,500,000.
      The number of stock Options and shares of Stock which may be issued
      pursuant to Section 9 of the Plan is 10,500,000 each. Of the foregoing
      stock options, the number of incentive stock Options which may be issued
      pursuant to the Plan is 10,500,000.

      In the event of a merger, reorganization, consolidation, recapitalization,
      separation, liquidation, stock dividend, stock split, share combination,
      or other change in the corporate structure of the Company affecting the
      shares of Stock, such adjustment shall be made in the number and class of
      shares of Stock which may be delivered under the Plan, and in the number
      and class of and/or price of shares of Stock subject to outstanding
      Options granted under the Plan, as may be determined to be appropriate and
      equitable by the Committee, in its sole discretion, to prevent dilution or
      enlargement of rights.

      11.21 Distribution Alternative. Effective November 17, 1995,
      notwithstanding the provisions of Section 6 and of Section 7, at any time
      during the calendar year prior to the calendar year during which a
      distribution(s) pursuant to a Savings Unit is scheduled to commence, a
      Participant may change his or her previous election(s) applicable to such
      Savings Unit to further defer the commencement of the distribution(s)
      pursuant to such Savings Unit to a subsequent calendar year, and in such
      case to also change the number of installments applicable to the
      distribution of the Savings Unit as follows: (a) the new election(s)
      applicable to such Savings Unit must conform with either Section 6, if the
      Retirement Alternative is the new selection for such Savings Unit, or
      Section 7, if the Specified Date Alternative is the new selection for such
      Savings Unit; (b) either the Retirement Alternative or the Specified Date
      Alternative may be selected for the new election(s) for a Savings Unit
      irrespective of the Alternative originally selected for such Savings Unit;
      (c) the commencement date for payments pursuant to such Savings Unit may
      be delayed to any point in time in a subsequent calendar year - the
      commencement date for payments may not be advanced to an earlier point in
      time; and (d) any number of installments may be selected pursuant to the
      new election(s) for a Savings Unit irrespective of the number of
      installments originally selected for such Savings Unit. Provided, however,
      in the event a Participant is involuntarily terminated from employment
      (which shall be deemed to include termination by reason of death), and
      such termination is for a reason other than for cause (i.e., willful and
      gross misconduct on the part of the Participant that is materially and
      demonstrably detrimental to the Company or any subsidiary thereof), and
      such termination is a Retirement (or in the case of Participant's death,
      Participant was Retirement eligible), then Participant (or Participant's
      Beneficiary(ies)) may make the change(s) to Participant's previous
      election(s) pursuant to this Section 11.21 at the time of Participant's
      termination of employment. Amounts with respect to which the Participant's
      election(s) are modified in accordance with the provisions of this Section
      11.21 shall continue to be subject to all provisions of this Plan
      including further distribution modifications in accordance with the
      provisions of the Section 11.21.






Section 12 - Participation in Other Plan(s)

      12.1 Participation in Predecessor Plans. Effective November 21, 1997, the
      plans of the Stock Savings Program shall be merged into the Stock Savings
      Plan. All Savings Units under the Stock Based Savings Plan or the
      Management Stock Savings Plan shall be transferred to this Plan as of that
      date and shall be governed by the terms of this Plan.

      12.2 Pacific Telesis Group 1996 Executive Deferred Compensation Plan or
      the Pacific Telesis Group Non-Qualified Savings Plan. If an Eligible
      Employee elects to participate in this Plan with respect to contributions
      during 1998, the Employee may not defer, under the Pacific Telesis Group
      1996 Executive Deferred Compensation Plan or the Pacific Telesis Group
      Non-Qualified Savings Plan, any compensation otherwise payable in 1998,
      and such election under this Plan shall operate as a termination of
      participation in such Pacific Telesis Group plans to the extent it relates
      to any deferrals of compensation otherwise payable in 1998.
