ASHLAND INC. REPORTS
MARCH QUARTER EARNINGS

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

                     FISCAL 2004: SECOND QUARTER HIGHLIGHTS

o        A 10-percent  increase in sales  revenues and a lower overall cost
         structure   contributed   to   improved   operating   income  from
         wholly-owned businesses compared to the previous winter quarter:

        -    Each of the Chemicals sector  divisions  achieved record March
             quarters - results from Ashland  Distribution  nearly tripled,
             Ashland Specialty Chemical nearly quadrupled and Valvoline was
             up 33 percent;

        -    In the Transportation  Construction sector, Ashland Paving And
             Construction reduced its  quarter-over-quarter  operating loss
             by 42 percent.

o        Higher manufacturing and crude oil costs resulted in lower profits
         from refining and marketing.

o        On March 19, 2004,  Ashland announced an agreement to transfer its
         38-percent  interest in Marathon  Ashland  Petroleum  LLC (MAP) to
         Marathon  Oil   Corporation,   subject  to  previously   disclosed
         conditions.

     Ashland Inc. today  reported a net loss of $16 million,  or 23 cents a
share,  for the quarter  ended March 31,  2004,  the second  quarter of the
company's  2004 fiscal year.  These  results  compared to a net loss of $39
million,  or 57 cents a share,  for the second  quarter of 2003.  Ashland's
loss from


                                  -more-





continuing  operations  for the  second  quarter  of 2004  amounted  to $11
million,  or 16 cents a share,  compared  to a loss of $37  million,  or 54
cents a share,  for the quarter a year ago. As  previously  disclosed,  the
difference between net income and income from continuing operations relates
principally to ongoing  quarterly charges of nearly $5 million for asbestos
liabilities.  The winter quarter is typically  Ashland's weakest due to the
seasonality of our businesses.

     For the six months ended March 31, 2004,  Ashland  reported net income
of $17  million,  or 25  cents  a  share,  compared  to a net  loss of $131
million, or $1.91 a share for the same period last year. Ashland had income
from  continuing  operations of $27 million,  or 39 cents a share,  for the
2004 period,  compared to a loss of $38 million,  or 56 cents a share,  for
the 2003 period.

     Performance from the Chemicals  sector,  which consists of the Ashland
Distribution, Ashland Specialty Chemical and Valvoline divisions, continued
to  improve.  March  quarter  operating  income for the sector  totaled $62
million, compared to $30 million for the 2003 quarter.

     Ashland  Distribution  achieved a record March quarter with  operating
income of $19  million  compared to $7 million in 2003.  Improved  customer
service  capabilities,  increased  operating  efficiency and effective cost
management have enabled Ashland Distribution to improve daily sales volumes
by 3 percent  compared  to the 2003  quarter.  For the first six  months of
fiscal 2004,  operating income more than doubled to $32 million compared to
$15 million last year.

     Ashland  Specialty  Chemical  reached record  operating  income of $19
million for the March quarter compared to $5 million in 2003. Slight margin
pressure  was more than offset by higher sales and the  division's  reduced
cost  structure.  Sales per  shipping day  increased by 7 percent.  For the
first six  months of fiscal  2004,  operating  income  was $42  million,  a
133-percent improvement over last year.

     Valvoline  reported  record  March  quarter  operating  income  of $24
million,  a 33-percent  increase  from the 2003 quarter.  Valvoline's  core
lubricant business improved with premium product sales volumes increasing 5
percent.  Valvoline  Instant Oil Change  (VIOC)  increased  non-oil  change
revenues  by 6 percent  and  premium  lubricant  oil  changes by 3 percent.
Valvoline's  international  operations  improved  due in  large  part  to a
4-percent  increase in lubricant  sales volumes and  strengthening  foreign
currencies. Additionally, Valvoline achieved record operating income of $45
million  for the first six months of fiscal  2004,  compared to $32 million
last year.

     The Transportation  Construction sector,  consisting of Ashland Paving
And  Construction,  Inc.  (APAC),  experienced an anticipated  loss for the
quarter of $33  million.  In  addition  to its lower cost  structure,  APAC
instituted a program to mitigate winter losses, contributing to its ability
to lower by 42 percent the  operating  loss  reported  in the prior  year's
quarter.  Looking  ahead to the summer  construction  season - during which
APAC has historically reported the majority of its earnings - the

                                  -more-




division  has  continued  to increase  its  construction  backlog,  or jobs
awarded but not yet completed. APAC increased the backlog by 5 percent to a
record $1.9 billion as of March 31, 2004.

     Operating  income from refining and marketing was $2 million  compared
to $21  million for the March 2003  quarter.  MAP  completed a  substantial
amount of planned  refinery  maintenance  during the quarter and expects to
run at full capacity  moving into the spring driving  season.  In addition,
MAP completed a number of other  projects such as a multi-year  improvement
project at its  Catlettsburg,  Ky.,  refinery and a 13,000  barrels per day
(bpd)  expansion of the crude oil processing  unit at its  Garyville,  La.,
refinery.  The latter  project  increased  MAP's overall crude oil capacity
from 935,000 bpd to 948,000 bpd.  Ashland's costs for this line of business
were unusually high due to  mark-to-market  charges on margin hedges and to
transaction  costs associated with the proposed transfer of MAP to Marathon
Oil Corporation.

     On March  19,  2004,  Ashland  announced  that the  company  signed an
agreement under which it would transfer its 38 percent  interest in MAP and
two other businesses to Marathon in a transaction structured to be tax free
and valued at  approximately  $3.0 billion.  The two other  businesses  are
Ashland's  maleic  anhydride  business and 61 Valvoline  Instant Oil Change
centers.  The  transaction  is  subject  to  several  previously  disclosed
conditions,   including  approval  by  Ashland's  shareholders,   customary
antitrust  review,  consent  from  public  debt  holders  and  receipt of a
favorable  private  letter  ruling from the Internal  Revenue  Service with
respect  to the tax  treatment.  While  there is  meaningful  risk that the
transaction  will not receive the  favorable  ruling from the IRS, in which
case the transaction  would not close,  Ashland  believes it is more likely
than not that this  transaction  will  receive a favorable  ruling.  If the
conditions are met, the  transaction is expected to close by the end of the
2004 calendar year.

     "I am pleased by our performance during the first six months of fiscal
2004,"  said James J.  O'Brien,  chairman  and CEO.  "We are  demonstrating
Ashland's  ability  to build and  maintain  strong  relationships  with our
customers and suppliers and to seize opportunities in an improving economy.
With a lower cost structure, we are able to focus on organic growth. Record
March quarter results from Ashland Distribution, Ashland Specialty Chemical
and Valvoline  indicate that our plan to drive  efficiency,  manage capital
and grow  value-creating  businesses is working. We look forward to further
executing our plans during the second half of this year."

     Today at 11:00 a.m.  (EDT),  Ashland will provide a live audio webcast
of its quarterly conference call with securities analysts. The webcast will
be accessible  through Ashland's  website,  www.ashland.com.  Following the
