                          STOCK INCENTIVE PLAN OF 1990

     This Second  Amendment  to the Atlanta Gas Light  Company  Long-Term  Stock
Incentive  Plan (the "Plan") is made and entered into this 16th day of December,
1994, by the Atlanta Gas Light Company (the "Company").

                              W I T N E S S E T H:

     WHEREAS,  the  Company  sponsors  the  Plan  to  provide  incentive  and to
encourage proprietary interest in the Company by its key employees, officers and
inside directors; and

     WHEREAS,  the  Company  believes  that it is in the  best  interest  of the
Company and its  employees to amend the Plan to provide for limited  beneficiary
designations and the extension of certain exercise periods; and

     WHEREAS,  Section 10 of the Plan  provides  that the  Company may amend the
Plan at any time; and

     WHEREAS,  the Board of  Directors  of the Company has adopted a  resolution
authorizing the amendment of the Plan;

     NOW, THEREFORE BE IT RESOLVED, that the Plan hereby is amended as follows:

     1.  Section 3 of the Plan shall be amended by deleting  that section in its
entirety and substituting in lieu thereof the following section:

            3. Stock.

               The stock subject to the Stock Rights and other provisions of the
               Plan shall be authorized but unissued or reacquired shares of the
               $5.00 par value common stock of the Company (the "Common Stock").
               Subject to  readjustment  in  accordance  with the  provisions of
               Section  8, the total  number of shares of the  Common  Stock for
               which Stock Rights may be granted to persons participating in the
               Plan shall not exceed in the aggregate  800,000  shares of Common
               Stock,  less any shares  used as payment  for SAR's  pursuant  to
               Section 6(a).  Notwithstanding  the  foregoing,  shares of Common
               Stock  allocable  to the  unexercised  portion of any  expired or
               terminated  Option may become  subject to Stock  Rights under the
               Plan.  Stock not subject to Stock  Rights  includes (i) shares of
               Restricted  Stock  which are  forfeited  for any  reason and (ii)
               shares used in payment of the Option  price for any Option  under
               the Plan.

     2.  Section  5(j)(ii)  of the  Plan  shall  be  amended  by  deleting  that
subsection  in its  entirety  and  substituting  in lieu  thereof the  following
subsection:

          (ii) Upon an Optionee's  retirement with the Company's  consent or the
               termination of an Optionee's  employment  due to  disability,  as
               determined by the Committee in its sole discretion, any Option or
               unexercised  portion  thereof  granted to him which is  otherwise
               exercisable shall terminate on and shall not be exercisable after
               12 months  from the date of the  Optionee's  retirement  with the
               consent  of the  Company  or after 3 months  from the date of the
               Optionee's  termination due to disability;  provided,  any ISO or
               unexercised portion thereof which remains unexercised on the date
               three months after the date on which such  Optionee  ceases to be
               an employee of the Company and any Subsidiary  shall convert to a
               Non-ISO for the remainder of its exercise period. Notwithstanding
               the above, the Committee may provide in the Option Agreement that
               such Option or any  unexercised  portion  thereof shall terminate
               sooner.  An Option shall be  exercisable  in accordance  with its
               terms and only for the number of shares  exercisable  on the date
               such





                           Optionee's employment ceases.

     3.  Section  5(j)(iii)  of the  Plan  shall be  amended  by  deleting  that
subsection  in its  entirety  and  substituting  in lieu  thereof the  following
subsection:

          (iii)In the event of the death of the  Optionee  while he or she is an
               employee of the Company or a Subsidiary  or within 3 months after
               the date on which such  Optionee's  employment  terminated due to
               retirement  with the Company's  consent or due to disability,  as
               determined by the Committee in its sole discretion, any Option or
               unexercised  portion  thereof  granted  to  him  or  her  may  be
               exercised by his or her  beneficiary,  as designated  pursuant to
               the  provisions of Section 5(p) of the Plan, at any time prior to
               the expiration of 1 year from the date of death of such Optionee,
               but in no event later than the date of  expiration  of the option
               period;  provided,  the  Committee  may  provide  in  any  Option
               Agreement  that such Option or any  unexercised  portion  thereof
               shall terminate sooner. Any exercise by a designated  beneficiary
               of the Optionee  shall be effected  pursuant to the terms of this
               Section  5 as if  such  designated  beneficiary  were  the  named
               Optionee.

     4. A new Section 5(p) shall be added to the Plan as follows:

          (p)  Designation of  Beneficiary.  Each Optionee shall be permitted to
               name one  person as  --------------------------  beneficiary  for
               each Option he or she is granted under the Plan.  The  designated
               beneficiary  shall have the rights described in Section 5(j)(iii)
               of the  Plan.  Each  Optionee  shall be  provided  a  beneficiary
               designation   form  by  the   Committee  and  may  designate  one
               individual as beneficiary  for each Option,  and that form should
               be  completed  and  returned to the  Committee.  If no  completed
               beneficiary  designation  form has been received by the Committee
               for an Option  upon the death of the  Optionee,  the  executor or
               administrator  of the  Optionee's  estate shall be considered the
               Optionee's designated beneficiary for that Option.

     5. The amendments  contained in this Second  Amendment to the Plan shall be
considered effective for all Options granted after January 1, 1994. In addition,
the amendments made by Items 2, 3 and 4 above shall be considered  applicable to
all Options (and their  respective  option  agreements)  granted  under the Plan
prior to that  date,  retroactive  to the  initial  effective  date of the Plan,
November 3, 1989.

     6.  Except as  specifically  set for  herein,  the terms of the Plan  shall
remain in full force and effect.


     IN WITNESS  WHEREOF,  the Company has caused this Second  Amendment  to the
Plan to be  executed by its duly  authorized  officer as of the date first above
written.
