ASHLAND INC.'S SECOND QUARTER
EARNINGS IMPROVE SIGNIFICANTLY

Covington, Ky. - The following was issued today by Ashland Inc. (NYSE:ASH):

                   FISCAL 2005: MARCH QUARTER HIGHLIGHTS

o    Net income of 44 cents a share compared to prior-year loss.
o    Chemical Sector operating income increased by 56 percent:
     -  Ashland  Distribution:  achieves second consecutive all-time record
        quarter;
     -  Ashland Specialty Chemical: profits more than double due in part to
        higher sales volumes;
     -  Valvoline:  price increases  offset volume  declines,  resulting in
        essentially even profits.
o    Transportation  Construction Sector experiences  operating loss due to
     lower production.
o    Refining and marketing experiences sharp increase in operating profits
     due to higher refinery output and margins.

     Ashland Inc. today  reported net income of $33 million,  or 44 cents a
share,  for the quarter ended March 31, the second quarter of the company's
2005 fiscal year. These results compare to a net loss of $16 million, or 23
cents a  share,  for the 2004  March  quarter.  The  prior-year  loss  from
continuing operations was $11 million, or 16 cents a share.

     For the six months ended March 31, 2005,  Ashland  reported net income
of $126 million,  or $1.72 a share,  compared to net income of $17 million,
or 25 cents a share for the same period last year.  Income from  continuing
operations  for the first six months of the prior year was $27 million,  or
39 cents a share.
     "Normal  seasonality  makes  the  March  quarter  our  most  difficult
earnings  period," said James J. O'Brien,  Ashland Inc.  chairman and chief
executive officer. "We improved operating income by $76 million compared to
last year's March  quarter,  despite  continued high raw material costs and
poor weather  conditions  in our paving and  construction  operating  area.
Improvements  from our other businesses - due in part to success in passing
on the high cost of materials influenced by hydrocarbon pricing - more than
offset disappointing results from our Transportation Construction Sector."
     Commenting  on  operations,  O'Brien  noted that the Chemical  Sector,
which includes the Ashland  Distribution,  Ashland  Specialty  Chemical and
Valvoline divisions, continues to make progress in its integration efforts.
Chemical  Sector  operating  income  grew  to  $97  million,  a  56-percent
improvement compared to the previous March quarter.
     Ashland  Distribution  achieved its second consecutive all-time record
quarter. Operating income for the March 2005 quarter was $34 million, up 79
percent over the previous year's quarter. Overall sales revenues were up 21
percent due to the division's ability to pass through price increases. This
division  is  building  solid  momentum  for  continued  growth by creating
consistent  processes,  sustaining a low-cost model and delivering value to
its customers.
     Ashland  Specialty  Chemical  reported record operating income for the
March 2005  quarter of $39  million,  up 105 percent over last year's March
quarter.  Sales  revenues  grew by 32 percent  due in part to an  8-percent
increase in thermoset resin volumes. Partial recovery of margins during the
quarter,  and the sale of an idle plant in Plaquemine,  La., which resulted
in a pre-tax gain of $7 million,  also contributed to the division's record
performance.
     Valvoline's  operating  income  for the  March  2005  quarter  was $24
million,  essentially  even with the  record  achieved  in the  March  2004
quarter.  Price  increases  enabled  Valvoline to maintain  profits despite
softer volumes and high raw material costs.  While  U.S.-branded  lubricant
sales volumes declined 7 percent, premium lubricant sales volumes increased
by 5 percent.
     The Transportation  Construction Sector, commercially known as Ashland
Paving And  Construction,  Inc.  (APAC),  reported an operating loss of $46
million for the March 2005  quarter,  compared to a $33 million loss in the
March 2004 quarter. The March quarter is typically APAC's slowest.  Hot-mix
asphalt  production  declined  16 percent  compared to the same period last
year, driven primarily by poor weather  conditions in APAC's operating area
and  higher  hydrocarbon  costs.  During  the  quarter,  APAC won two major
highway  construction  jobs in Tennessee and Florida totaling $135

                                  -more-

million. At March 31, APAC's construction  backlog,  which consists of work
awarded and funded but not yet performed, was a record $2.1 billion.
     Operating  income from  refining and marketing was $61 million for the
March 2005  quarter,  compared  to $2  million  in the March 2004  quarter.
Marathon  Ashland  Petroleum LLC (MAP) benefited from greater  discounts on
high-sulfur  crude oil and less planned  maintenance.  Crude oil throughput
was 17  percent  higher  than  during the March  2004  quarter.  During the
quarter,  38-percent  owned MAP  realized a $12 million loss and recorded a
$61 million  mark-to-market  charge for crack spread derivative  contracts.
MAP also  recorded a $73  million  in-transit  crude oil charge  during the
March 2005 quarter.
     "Our  performance  during the second  quarter  is  encouraging,"  said
O'Brien.  "Due to the hard work and dedication of our employees  worldwide,
we  continue to improve how we take our  products  and  services to market,
meet the needs of our customers and manage our supplier relationships."
     O'Brien added that Ashland continues to identify and implement process
improvements  that are enabling  more  effective  management  of rising raw
material costs and improving operational efficiency.

UPDATE ON THE PROPOSED TRANSFER OF INTEREST IN MAP
     On March 19, 2004, Ashland announced the signing of an agreement under
which it  would  transfer  its  38-percent  interest  in  Marathon  Ashland
Petroleum LLC and two  wholly-owned  businesses to Marathon Oil Corporation
in a  transaction  structured  to be  generally  tax  free  and  valued  at
approximately $3 billion. The two businesses are Ashland's maleic anhydride
business and 61 Valvoline  Instant Oil Change  centers.  The transaction is
subject to several previously disclosed conditions,  including receipt of a
private letter ruling from the IRS with respect to the tax treatment of the
transaction. The IRS has indicated that it will not provide all the rulings
requested by Ashland and Marathon,  and discussions are continuing with the
IRS on modifications to the proposed transaction. In addition, as disclosed
on  April  13,  2005,   Ashland  and  Marathon  are   discussing   possible
alternatives  with  respect to the  proposed  transaction.  There can be no
assurance that an agreement on an alternative transaction will be reached.
     Cash  distributions  from MAP have been suspended pending the transfer
of the company's interest in the joint venture to Marathon. If the proposed
transaction  closes,  Ashland would receive proceeds equal to 38 percent of
MAP's  distributable  cash at the time of closing.  If the transaction does
not close,  Ashland  would  receive its share of these funds as part of its
normal distributions. Ashland's share on March 31, 2005, was $560 million.
     Today at 10:00 a.m.  (EDT),  Ashland will provide a live audio webcast
of its quarterly conference call with securities analysts. The webcast will
