               SJI Posts Strong Third Quarter Performance Improvement
                        Delivers Nine Month Record Earnings

Folsom, NJ-South Jersey Industries (NYSE:SJI) delivered a $0.14 per share
improvement in earnings from continuing operations for the third quarter.
Commenting on SJI's third quarter results, Charles Biscieglia, Chairman and CEO
of SJI, said, "Consistent execution of our strategy has enabled SJI to deliver
strong earnings performance for not only the third quarter and first nine months
of 2003, but the last five years as well.
         The results of the first nine months of 2003 keep SJI on track to
deliver the earnings per share growth for the year of at least the 7% to 10 %
that we outlined previously," continued Biscieglia. SJI's earnings from
continuing operations for the first nine months of 2003 were a record $23.2
million or $1.87 per share compared with $17.2 million, or $1.44 per share for
2002.
         Although SJI typically produces a loss in the third quarter when
natural gas usage is minimal, the company was able to minimize its third quarter
loss from continuing operations to $1.6 million, or $0.13 per share. This
compares favorably with a loss of $3.2 million, or $0.27 per share, for the same
period in 2002.

Third Quarter 2003 Highlights:

         Non-Utility Operations Net Income Increases

o        Net income contribution for the quarter from our non-utility business
                  increased to $2.2 million due to strong performance in our
                  wholesale energy marketing and on-site energy production
                  businesses. These results were partially offset by lower than
                  targeted comparative net income posted by our retail gas
                  marketing business.

o        South Jersey Resources Group, SJI's wholesale energy marketing
                  business, increased its contribution to SJI's net income to
                  $1.2 million for the third quarter of 2003, a $1 million
                  increase over the prior year period. The profit increase
                  resulted from effectively managing storage and pipeline
                  capacity rights while serving the growing needs of our
                  wholesale customer base.

o                 Marina Energy, SJI's on-site energy production business,
                  contributed almost $700,000 to earnings for the quarter, due
                  in large part to the July commencement of full operations at
                  our thermal energy plant serving the Borgata Hotel Casino &
                  Spa in Atlantic City, N.J. Since start-up, operation of the
                  plant has exceeded our expectations for the facility.

   SJI Third Quarter 2003 Earnings Report-ADD 1

o                 South Jersey Energy, SJI's non-regulated energy supplier, had
                  90,300 residential, commercial and industrial customers at the
                  end of the third quarter of 2003 compared with 66,400 at the
                  end of the same period in 2002, a 36% increase. SJE added
                  almost 1,900 customers during the third quarter of 2003. Net
                  income performance for the quarter at our retail gas marketing
                  business was approximately $190,000 lower than the same period
                  last year. However, the large customer increase experienced
                  over the last year should significantly benefit fourth quarter
                  2003 results.

              Utility Operations
              Continued Strong Customer Growth Fuels Utility

o                 At South Jersey Gas Company, our regulated utility, a larger
                  customer base, lower interest expenses and a 10% performance
                  improvement from our appliance service business offset the
                  effects of increased administrative expenses that include
                  health and pension costs. Because natural gas usage for
                  heating is typically minimal in the third quarter, expenses
                  associated with serving customers exceed revenues earned from
                  those customers. The utility net loss for the quarter of $3.8
                  million mirrored third quarter 2002 results.

o                 Fueled by new construction and conversions from other energy
                  sources, SJG's customer total climbed to 299,600 at September
                  30, 2003, an increase of 7,900 over the same period last year.
                  The 2.7% customer growth is well above the industry average of
                  1.5%. We continue to project that customer growth will be
                  close to 3% for the full year based upon the strength of
                  development in our service territory. Customer growth
                  contributes significantly to annual profitability.

o                 SJG took advantage of historically low interest rates by
                  issuing $110 million of long-term debt during the quarter at
                  an average weighted interest rate of 4.97% and with an average
                  life of 17 years. Proceeds of the debt were used to repay
                  short-term borrowings outstanding under existing lines of
                  credit. Those short-term line borrowings were incurred to
                  temporarily finance the expansion of SJG's gas distribution
                  system and to redeem high rate debt. During the quarter we
                  called $32 million of 6.95% First Mortgage Bonds, the
                  refinancing of which will provide an earnings benefit for the
                  remainder of 2003, 2004 and beyond.
