                              EXPLANATORY NOTE

     This  Post-Effective  Amendment No. 1 by the Registrant relates to (a)
the registration  statement on Form S-3  (Registration  No.  333-105396) of
Ashland Inc., a Kentucky  corporation ("Old Ashland"),  relating to 296,385
shares of Old Ashland common stock,  par value $1.00 per share, and (b) the
following  registration  statements on Form S-3 of old Ashland  relating to
the  following  shares of Old  Ashland  common  stock,  par value $1.00 per
share:  Registration No. 333-78675 registering 68,925 shares;  Registration
No.  333-36842  registering  96,600  shares;   Registration  No.  333-54762
registering  149,300 shares;  and Registration  No.  333-82830  registering
265,100 shares.  The  above-mentioned shares were previously registered for
issuance  under the Ashland Inc.  Stock Option Plan for  Employees of Joint
Ventures,  which  has  been  assumed  by  the  Registrant  pursuant  to the
Transactions (defined below).

         Pursuant to Rule 414 promulgated under the Securities Act of 1933,
as amended (the  "Securities  Act"),  the Registrant  hereby adopts each of
Registration Statement Nos. 333-105396, 333-78675, 333-36842, 333-54762 and
333-82830 (the "Old Ashland  Registration  Statements")  as its own for all
purposes of the Securities Act and the Securities  Exchange Act of 1934, as
amended (the "Exchange  Act"),  and,  accordingly,  affirms that the common
shares  registered under the Old Ashland  Registration  Statements shall be
common shares of the Registrant.

         Pursuant  to Rule 429 under the  Securities  Act,  the  prospectus
included  in this  Registration  Statement  is a  combined  prospectus  and
relates to the  registered  but unsold  shares of common  stock  previously
registered under the Old Ashland Registration Statements as follows: 10,030
unsold shares registered under Registration Statement No. 333-78675; 13,164
unsold shares registered under Registration Statement No. 333-36842; 13,589
unsold shares registered under Registration Statement No. 333-54762; 24,332
unsold shares registered under  Registration  Statement No. 333-82830;  and
73,871  unsold  shares   registered   under   Registration   Statement  No.
333-105396.   Pursuant  to  Rule  429  under  the   Securities   Act,  this
post-effective amendment constitutes Post-Effective Amendment No. 1 to each
of these Registration Statements.

         After giving effect to the filing of this Post-Effective Amendment
No. 1, the plan to which the  Registration  Statement  relates  will be the
Ashland Inc. Stock Option Plan for Employees of Joint Ventures,  as assumed
by the Registrant upon the authority granted by resolutions of the board of
directors  of the  Registrant  at a special  meeting held on June 29, 2005.
After giving effect to the filing of this  Post-Effective  Amendment No. 1,
the  Registrant  will be the issuer of an  aggregate  of 876,310  shares of
common stock (the "Common Stock"), par value $0.01 per share, registered as
follows:  296,385 shares of Common Stock registered under this Registration
Statement No.  333-105396;  68,925 shares of Common Stock  registered under
Registration  Statement  No.  333-78675;  96,600  shares  of  Common  Stock
registered under  Registration  Statement No. 333-36842;  149,300 shares of
Common Stock registered under  Registration  Statement No.  333-54762;  and
265,100 shares of Common Stock registered under Registration  Statement No.
333-82830, and Old Ashland will not be a registrant under such registration
statements.

         Old Ashland and Marathon Oil Corporation,  a Delaware  corporation
("Marathon"),  entered  into an  agreement  under  which  Old  Ashland  has
transferred  its interest in Marathon  Ashland  Petroleum LLC ("MAP"),  its
maleic  anhydride  business and 60 Valvoline  Instant Oil Change Centers in
Michigan and northwest  Ohio to a wholly owned  subsidiary of Marathon (the
"Transactions").  The Transactions  were consummated on June 30, 2005. As a
result of the Transactions, among other things, shareholders of Ashland are
entitled to receive (1) shares of Marathon  common stock with a total value
of $915 million in exchange for the shares of Old Ashland common stock they
owned  as of June 30,  2005,  and (2) new  shares  of  common  stock of the
Registrant  as  successor  corporation  to  Old  Ashland.  As  part  of the
Transactions, Old Ashland has merged with and into one of its subsidiaries.
As a result of the  Transactions,  the existing  businesses  of Old Ashland
other than those  transferred  to  Marathon's  subsidiary  are owned by the
Registrant,  the successor to Old Ashland through a series of mergers,  and



the  Registrant  is a  publicly-traded  company  owned  by the Old  Ashland
shareholders.  The  management  and  board  of  directors  of  Old  Ashland
continued as the management and board of directors of the  Registrant.  Old
Ashland  common  stock was  traded on the New York Stock  Exchange  and the
Chicago  Stock  Exchange  under  the  symbol  "ASH";  and,   following  the
completion of the Transactions,  the Registrant's common stock is traded on
the New York Stock  Exchange and the Chicago Stock  Exchange under the same
symbol. As part of the Transactions, the name of the Registrant was changed
from "New EXM Inc." to "Ashland Inc."

         The  Transactions  and related matters are more fully described in
the proxy statement/prospectus of the Registrant,  constituting part of the
Registrant's  registration  statement on Form S-4, as amended (Registration
No. 333-119689-01).

                  Ashland Inc. ("Old Ashland") and Marathon Oil Corporation

and the  Chicago  Stock  Exchange  under  the same  symbol.  As part of the
transactions, the name of Ashland was changed to "Ashland Inc."

RISK FACTORS

THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS.

                  This  prospectus  contains  forward-looking   statements.
These statements relate to our future financial performance. In some cases,
you can identify  forward-looking  statements by terminology such as "may,"
"will,"   "should,"   "expects,"   "plans,"   "anticipates,"    "believes,"
"estimates,"  "predicts,"  "potential," "continue" or the negative of these
terms  or  other   comparable   terminology.   These  statements  are  only
predictions.  Actual events or results may differ materially. In evaluating
these  statements,   you  should  specifically  consider  various  factors,
including the risks outlined in these risk factors,  any of which may cause
our  actual  results  to  differ   materially   from  any   forward-looking
statements.

RISKS RELATED TO ASHLAND AND ITS BUSINESS

ASHLAND  WILL  NOT  HAVE  ACCESS  TO THE  CASH  FLOW  FROM  THE  BUSINESSES
TRANSFERRED TO MARATHON,  WHICH COULD ADVERSELY IMPACT  ASHLAND'S  REVENUES
AND OPERATING RESULTS.

                  The  interest in MAP, the maleic  anhydride  business and
the 60 VIOC centers have  generated  funds from  operations  that have been
used in the  businesses  that will be operated by Ashland and for Ashland's
general  corporate  purposes.  In each of the last three full fiscal years,
distributions  from  MAP  have  represented  a  majority  of Old  Ashland's
operating  cash flows.  Since the closing of the  transactions,  Ashland no
longer has  access to the cash flow from the  interest  in MAP,  the maleic
anhydride  business or the 60 VIOC centers,  which could  adversely  impact
Ashland's revenues and operating results.

ASHLAND IS  RESPONSIBLE  FOR, AND HAS FINANCIAL  EXPOSURE TO, OLD ASHLAND'S
LIABILITIES  FROM CLAIMS  ALLEGING  PERSONAL  INJURY  CAUSED BY EXPOSURE TO
ASBESTOS,  WHICH WOULD REDUCE  ASHLAND'S CASH FLOWS AND  PROFITABILITY  AND
COULD IMPAIR ITS FINANCIAL CONDITION.

                  Ashland is subject to  liabilities  from claims  alleging
personal  injury  caused  by  exposure  to  asbestos.  Such  claims  result
primarily from indemnification obligations undertaken in 1990 in connection
with the sale of Riley Stoker Corporation ("Riley"), a former subsidiary of
Old Ashland.  Although Riley was neither a producer nor a  manufacturer  of
asbestos,   its  industrial  boilers  contained  some   asbestos-containing
components  provided by other companies.  As a result of the  transactions,
Ashland  is  responsible   for,  and  has  financial   exposure  to,  these
liabilities,  which could reduce Ashland's cash flows and profitability and
impair its financial  condition.  For a description of the claims  alleging
personal injury caused by exposure to asbestos,  which number  approximates
185,000, and the associated reserves and available insurance,  see "Note G.
Litigation,  Claims and Contingencies" to Ashland's condensed  consolidated
financial statements contained in its quarterly report on Form 10-Q for the
fiscal quarter ended June 30, 2005,  which is  incorporated by reference in
this prospectus.

ASHLAND IS  RESPONSIBLE  FOR, AND HAS FINANCIAL  EXPOSURE TO, OLD ASHLAND'S
OTHER   LIABILITIES,   WHICH  WOULD   REDUCE   ASHLAND'S   CASH  FLOWS  AND
PROFITABILITY AND COULD IMPAIR ITS FINANCIAL CONDITION.

                  As a result of the  transactions,  Ashland is responsible
for,  and  has   financial   exposure  to,  all  of  the   asbestos-related
liabilities, substantially all of the environmental liabilities (other than
certain  liabilities  relating to MAP) and other liabilities of Old Ashland
and its  subsidiaries  other than  liabilities  incurred by ATB Holdings in
connection with the transactions.

                  Additionally,  claimants  might  seek  to  hold  Marathon
liable for obligations of Ashland. Ashland has agreed to indemnify Marathon
for  liabilities  and costs that  Marathon may incur  relating to Ashland's
liabilities  (other than  certain  liabilities  relating  to MAP).  See the
section  entitled  "The  Master  Agreement--Indemnification"  in our  proxy
statement/prospectus,  constituting  part of our registration  statement on
Form S-4,  as amended  (Registration  No.  333-119689-01),  relating to the
transactions, which is incorporated herein by reference.

ASHLAND HAS LIMITED USE OF THE PROCEEDS FROM THE PARTIAL REDEMPTION AND THE
CAPITAL CONTRIBUTION RECEIVED IN THE TRANSACTIONS TO PAY DIVIDENDS OR OTHER
DISTRIBUTIONS  OR COMPLETE  SHARE  REPURCHASES  WHICH COULD HAVE AN ADVERSE
IMPACT ON ASHLAND'S STOCK PRICE.

                                     1

                  From  June  30,  2005,  the  date of the  closing  of the
transactions,  through the sixth  anniversary  of the closing,  Ashland has
agreed not to pay any dividend or other  distribution or repurchase  shares
of its common stock using proceeds  received from the transactions  without
the  consent of  Marathon  if, at the time of the  declaration  or payment,
Ashland is or would be (after giving effect to the payment) insolvent under
any applicable  fraudulent transfer or conveyance law as determined in good
faith by  Ashland's  board of directors in  accordance  with its  fiduciary
duties under applicable law. In addition, any share repurchases must comply
with Internal  Revenue Service  Revenue  Procedure  96-30,  which generally
requires  that (i) the shares be  repurchased  in the open  market and (ii)
Ashland not intend to repurchase more than 20% of its  outstanding  shares.
Ashland's  limited use of the proceeds from the partial  redemption and the
capital  contribution to pay dividends or other  distributions  or complete
share repurchases could have an adverse impact on Ashland's stock price.

ASHLAND  MAY NOT BE ABLE TO  SUCCESSFULLY  USE THE  PROCEEDS OF THE PARTIAL
REDEMPTION RECEIVED IN THE TRANSACTIONS IN A VALUE-GENERATING  MANNER WHICH
COULD  REDUCE  ITS  FUTURE  RATE OF  GROWTH,  PROFITABILITY  AND  OPERATING
RESULTS.

                  Ashland  may use  the  cash  proceeds  from  the  partial
redemption for general corporate purposes, which may include the funding of
pension obligations and expanding its business through both internal growth
and future business  acquisitions.  Ashland may not be able to successfully
identify uses for those  proceeds that will generate  value for Ashland and
its shareholders  which could reduce  Ashland's  future rate of growth.  In
addition,  in connection with possible future  business  acquisitions,  the
process  of  integrating   acquired   operations  into  Ashland's  existing
operations may result in unforeseen operating  difficulties and may require
significant  financial  resources that would otherwise be available for the
ongoing  development  or  expansion  of its  business  which  could  reduce
Ashland's profitability and operating results.

ASHLAND HAS INCURRED AND WILL INCUR SUBSTANTIAL OPERATING COSTS AND CAPITAL
EXPENDITURES AS A RESULT OF ENVIRONMENTAL AND HEALTH AND SAFETY LIABILITIES
AND REQUIREMENTS,  PARTICULARLY RELATING TO ITS CHEMICAL BUSINESSES,  WHICH
COULD REDUCE ASHLAND'S RESULTS OF OPERATIONS AND PROFITABILITY.

                  Ashland is subject to various  U.S.  and foreign laws and
regulations  relating to  environmental  protection  and worker  health and
safety.  These laws and regulations  regulate discharges of pollutants into
the air and water, the management and disposal of hazardous  substances and
the cleanup of contaminated  properties.  The costs of complying with these
laws and  regulations  can be  substantial  and may increase as  applicable
requirements  become  more  stringent  and new  rules are  implemented.  If
Ashland violates the requirements of these laws and regulations,  it may be
forced to pay substantial fines, to complete additional costly projects, or
to modify or curtail its operations to limit contaminant emissions.

                  Ashland is  responsible  for, and has financial  exposure
to, substantially all of the environmental  liabilities (other than certain
liabilities  relating  to MAP) and other  liabilities  of  Ashland  and its
subsidiaries.  Ashland  investigated and remediated a number of its current
and former properties.  At June 30, 2005, such locations included 102 waste
treatment or disposal  sites where Ashland was  identified as a potentially
responsible party under Superfund or similar state laws,  approximately 130
current  and former  operating  facilities  (including  certain  facilities
conveyed  to MAP) and about 1,220  service  station  properties.  Ashland's
environmental remediation costs were approximately $39 million for the nine
months  ended  June  30,  2005.   Ashland's   reserves  for   environmental
remediation  amounted to $177  million at June 30, 2005 and  reflected  its
estimates of the most likely  costs that will be incurred  over an extended
period  to  remediate  identified   conditions  for  which  the  costs  are
reasonably  estimable,   without  regard  to  any  third-party  recoveries.
Engineering  studies,  probability  techniques,  historical  experience and
other  factors are used to identify and evaluate  remediation  alternatives
and  their  related  costs  in  determining  the  estimated   reserves  for
environmental  remediation.  Environmental remediation reserves are subject
to  numerous  inherent  uncertainties  that  affect  Ashland's  ability  to
estimate its share of the costs. Such uncertainties  involve the nature and
extent of  contamination  at each  site,  the  extent of  required  cleanup
efforts under existing environmental  regulations,  widely varying costs of
alternate  cleanup  methods,  changes  in  environmental  regulations,  the
potential effect of continuing improvements in remediation technology,  and
the number and financial strength of other potentially  responsible parties
at multiparty sites.  Ashland regularly adjusts its reserves as remediation
continues.

SEVERAL OF  ASHLAND'S  BUSINESSES  ARE  CYCLICAL  IN NATURE,  AND  ECONOMIC
DOWNTURNS OR DECLINES IN DEMANDS FOR CERTAIN  DURABLE  GOODS MAY REDUCE ITS
PROFITABILITY AND LIMIT ITS ABILITY TO GENERATE REVENUES.

                  The profitability of Ashland's  businesses is susceptible
to downturns in the economy,  particularly downturns in the segments of the
U.S.  economy related to the purchase and sale of durable goods,  including
the housing, construction, automotive, marine and semiconductor industries.
Both  overall   demand  for   Ashland's   products  and  services  and  its
profitability  may  decline as a direct  result of an  economic  recession,
inflation,  changes in the prices of hydrocarbons  and other raw materials,
consumer  confidence,  interest rates or governmental  fiscal policies.  In
addition,  Ashland may experience  significant changes in its profitability
as a result of  variations  in sales,  changes  in  product  mix or pricing
competition.

ADVERSE CHANGES IN PREVAILING  CLIMATE OR WEATHER MAY NEGATIVELY AFFECT THE
PERFORMANCE OF SOME OF ASHLAND'S  OPERATIONS,  WHICH COULD REDUCE ASHLAND'S
RESULTS OF OPERATIONS AND PROFITABILITY.

                  Extreme variations from normal climatic  conditions could
have a significant  effect on the operating results of APAC's  construction
operations.  In particular,  unfavorable weather conditions could delay the
completion of construction  projects, and may require the use of additional
resources.  In  addition,  certain of the products  sold by  Valvoline  are
seasonal in nature,  and thus demand for those  products may decline due to
significant  changes in prevailing  climate and weather  conditions such as
floods, frozen rivers and hurricanes.

ASHLAND'S  FINANCING COSTS MAY BE HIGHER THAN OLD ASHLAND'S FINANCING COSTS
WHICH COULD ADVERSELY IMPACT  ASHLAND'S  ABILITY TO OBTAIN FUTURE FINANCING
ON ACCEPTABLE TERMS AND ASHLAND'S RESULTS OF OPERATIONS AND CASH FLOWS.

                  Ashland will have to raise  financing with the support of
a reduced pool of less diversified  assets,  and Ashland may not be able to
secure  adequate  debt or equity  financing  on terms  that would have been
available  to Old  Ashland.  Therefore,  the cost to Ashland  of  financing
without the 38% interest in MAP, the maleic  anhydride  business and the 60
VIOC  centers,  could  be  higher  than the cost of  financing  with  these
businesses as part of the company which could  adversely  impact  Ashland's
ability  to obtain  future  financing  on  acceptable  terms and  Ashland's
results of operations and cash flows.

                  The credit  ratings of Ashland may be different  from the
ratings of Old Ashland.  Differences  in credit ratings affect the interest
rate charged on financings,  as well as the amounts of indebtedness,  types
of financing  structures  and debt markets that may be available to Ashland
following the transactions. Ashland may not be able to raise the capital it
requires on  favorable  terms  following  the closing of the  transactions.
Therefore,  the cost to Ashland of  financing  without the 38%  interest in
MAP, the maleic anhydride business and the 60 VIOC centers, could be higher
than the cost of financing  with these  businesses  as part of the company,
which could adversely impact  Ashland's  ability to obtain future financing
on acceptable terms and Ashland's results of operations and cash flows.

ASHLAND MAY ISSUE PREFERRED  STOCK WHOSE TERMS COULD  ADVERSELY  AFFECT THE
VOTING POWER OR VALUE OF ITS COMMON STOCK.

Ashland's  articles of  incorporation  authorizes it to issue,  without the
approval of its  shareholders,  one or more  classes or series of preferred
stock having such preferences, powers and relative, participating, optional
and other rights,  including  preferences  over its common stock respecting
dividends  and  distributions,  as its  board of  directors  generally  may
determine.  The terms of one or more classes or series of  preferred  stock
could adversely impact the voting power or value of Ashland's common stock.
For example,  Ashland could grant  holders of preferred  stock the right to
elect some number of its  directors  in all events or on the  happening  of
specified  events or the right to veto specified  transactions.  Similarly,
the  repurchase or redemption  rights or  liquidation  preferences  Ashland
could assign to holders of preferred  stock could affect the residual value
of its common stock. See the sections entitled  "Description of New Ashland
Capital Stock--Preferred Stock" and "Comparison of the Rights of Holders of
Common Stock" in our proxy  statement/prospectus,  constituting part of our
registration   statement  on  Form  S-4,  as  amended   (Registration   No.
333-119689-01),  relating to the transactions, which is incorporated herein
by reference.

PROVISIONS OF ASHLAND'S  ARTICLES OF INCORPORATION AND BY-LAWS,  ITS RIGHTS
AGREEMENT  AND  KENTUCKY  LAW  COULD  DETER  TAKEOVER  ATTEMPTS  THAT  SOME
SHAREHOLDERS MAY CONSIDER DESIRABLE, WHICH COULD ADVERSELY AFFECT ASHLAND'S
STOCK PRICE.

                  Provisions  of Ashland's  articles of  incorporation  and
by-laws make acquiring  control of Ashland without the support of its board
of directors  difficult  for a third  party,  even if the change of control
would  be  beneficial  to  Ashland  shareholders.   Ashland's  articles  of
incorporation and by-laws contain:

     o    provisions relating to the classification, nomination and removal
          of its directors;

     o    provisions  limiting  the right of  shareholders  to call special
          meetings of its board of directors and shareholders;

     o    provisions  regulating the ability of its  shareholders  to bring
          matters for action at annual meetings of its shareholders; and

     o    the  authorization  given to its board of  directors to issue and
          set the terms of preferred stock.

In addition,  Ashland has  succeeded to Old  Ashland's  shareholder  rights
agreement,  which would cause  extreme  dilution to any person or group who
attempts  to acquire a  significant  interest  in Ashland  without  advance
approval of its board of directors. Ashland's articles of incorporation and
the laws of Kentucky impose some restrictions on mergers and other business
combinations between Old Ashland and any beneficial owner of 10% or more of
the voting power of its  outstanding  common stock.  The existence of these
provisions  may  deprive  you of any  opportunity  to sell your shares at a
premium over the  prevailing  market price for Ashland  common  stock.  The
potential  inability of Ashland  shareholders  to obtain a control  premium
could  adversely  affect the market  price for its  common  stock.  See the
sections entitled  "Description of Common Stock of Ashland" and "Comparison
of   the   Rights   of   Holders   of   Common    Stock"   in   our   proxy
statement/prospectus,  constituting  part of our registration  statement on
Form S-4,  as amended  (Registration  No.  333-119689-01),  relating to the
transactions,  which is incorporated herein by reference, for a description
of these and other provisions.

                                ASHLAND INC.

                  Ashland's  businesses  are  grouped  into  five  industry
segments: APAC (as defined below); Ashland Distribution;  Ashland Specialty
Chemical;  Valvoline;  and Refining and  Marketing.  Financial  information
about each of these segments for the three fiscal years ended September 30,
2004 is set forth on pages F-26 and F-27 of Ashland's annual report on Form
10-K, as amended,  for the fiscal year ended September 30, 2004,  which has
been incorporated by reference in this proxy statement/prospectus.

                  Ashland   Paving   And   Construction,   Inc.   and   its
subsidiaries  ("APAC") perform asphalt and concrete  contract  construction
work,  including  highway  paving and  repair,  excavation  and grading and
bridge  construction,  and produce  asphaltic mix and  ready-mix  concrete,
crushed stone and other aggregate in the southern and mid-continent regions
of the United States.

                  Ashland Distribution distributes chemicals,  plastics and
resins in North America and plastics in Europe.  Ashland  Distribution also
provides environmental services.

                  Ashland  Specialty  Chemical  is focused  on two  primary
businesses:  thermoset  resins and water  technologies.  It is a  worldwide
supplier of specialty chemicals serving industries including:  building and
construction;  commercial and institutional  water treatment;  graphic arts
and printing;  industrial water treatment; marine; metal casting; packaging
and converting; pulp and paper; recreational marine; and transportation.

                  Ashland's  maleic anhydride  business  contributed to ATB
Holdings  (and  ultimately to Marathon) in the  transactions  was a part of
Ashland's  Specialty  Chemicals  segment.  The  maleic  anhydride  business
produced  maleic  anhydride  at its plant in Neal,  West  Virginia.  Maleic
anhydride is used in the production of unsaturated  polyester resins,  lube
oil  additives,  co-polymers,  alkyd  resins,  fumaric  and malic acids and
agricultural  chemicals.  The production  capacity of the maleic  anhydride
business was 104 million pounds per year prior to the transactions.

                  Valvoline is a producer and marketer of premium  packaged
motor  oil  and  automotive   chemicals,   including  appearance  products,
antifreeze,  filters and automotive fragrances.  In addition,  Valvoline is
engaged in the "fast oil change" business  through outlets  operating under
the Valvoline  Instant Oil Change(R) name. As of June 30, 2005, there were
360 company-owned and 400 franchised VIOC centers operating in 40 states.

                  The 60 Valvoline  Instant Oil Change  centers in Michigan
and northwest Ohio contributed to ATB Holdings (and ultimately to Marathon)
in the transactions  provided services to the passenger car and light truck
motor oil market.

                  Ashland's   Refining  and  Marketing   segment  consisted
primarily of its 38% interest in MAP, which was transferred pursuant to the
transactions.

                  Ashland is a  Kentucky  corporation,  organized  in March
2004, with its principal  executive  offices  located at 50 E.  RiverCenter
Boulevard,  Covington,  Kentucky 41011 (Mailing Address:  50 E. RiverCenter
Boulevard, P.O. Box 391, Covington,  Kentucky 41012-0391) (Telephone: (859)
815-3333).  Ashland is the successor corporation to Old Ashland,  which was
organized on October 22, 1936.



                              USE OF PROCEEDS

                  Ashland  will use the net  proceeds it receives  from the
sale,  in  connection  with the  exercise of the options  described in this

                                  THE PLAN

General Plan Information

                  Marathon  Ashland  Petroleum  LLC,  or  MAP,  was a joint
venture  between  Marathon  Oil  Company,  a  subsidiary  of  Marathon  Oil
Corporation,  and Old Ashland our  predecessor  corporation.  Old Ashland's
management  determined that it would be in Old Ashland's best interest that
certain  MAP  officers  and  employees  have an  ownership  interest in Old
Ashland. On each of September 17, 1998,  September 16, 1999,  September 21,
2000,  September 20, 2001 and September  19, 2002,  Old Ashland's  board of
directors approved the grant of a number of options to purchase Old Ashland
common stock to certain  officers and  employees of MAP. As a result of the
transactions,  and as further  described below under  "Adjustments",  these
options are now options to purchase  Ashland common stock.  Throughout this
prospectus,  we will refer to the stock options as the "MAP stock options,"
the MAP employees  that were granted MAP stock options as the  "recipients"
and the company's Personnel and Compensation  Committee as the "Committee."
Old Ashland granted the MAP stock options under the terms and conditions of
the notices of grant and the Ashland Inc.  Stock Option Plan for  Employees
of Joint Ventures,  a plan, approved by Old Ashland's board of directors on
September 17, 1998,  specifically  designated to grant options to employees
of joint  ventures in which Ashland has an interest.  The MAP stock options
supplemented   stock  options  and/or   restricted  stock  granted  to  the
recipients  by  Marathon  Oil  Company  in amounts  recommended  by the MAP
Executive  Committee.  In connection  with the  transactions,  the plan was
assumed by Ashland upon the authority  granted by  resolutions of Ashland's
board of directors at a special meeting held on June 29, 2005.

                  This section contains a summary of the material terms and
provisions  of the Ashland Inc.  Stock  Option Plan for  Employees of Joint
Ventures,  including  terms  relating  to  the  transactions,  and  is  not
complete.  You should refer to the documents relating to the plan which are
incorporated  by  reference  as exhibits to the  registration  statement of
which  this  prospectus  is a part.  If  necessary,  we will in the  future
provide  supplemental  material to update the  available  information  with
respect to the plan, the MAP stock options and the underlying shares of our
common stock to holders of MAP stock options.  You should also refer to the
master  agreement  attached  as Annex A to our proxy  statement/prospectus,
constituting  part of our  registration  statement  on Form S-4, as amended
(Registration No. 333-119689-01) which is incorporated herein by reference.

                  The plan is not a qualified  deferred  compensation  plan
under Section 401(a) of the Internal Revenue Code of 1986, as amended,  and
is exempt from the provisions of the Employee  Retirement  Income  Security
Act of 1974, as amended.

                  Participants   under  the  plan  may  obtain   additional
information  regarding the plan and its  administration  from the Office of
the Secretary,  Ashland Inc., 50 E.  RiverCenter  Boulevard,  P.O. Box 391,
Covington,  KY 41012-0391.  The  Secretary's  Office may also be reached by
phone at 859-815-3333.

Purpose of the Plan

                  The  principal  purpose  of the  plan is to  promote  our
interests and those of Ashland's  shareholders  by attracting and retaining
management personnel whose training, experience and abilities contribute to
the success of joint  ventures  in which we have an interest  and which our
board of directors  designates  as being  governed by the plan.  To achieve
this  purpose,  Ashland  granted MAP stock options to selected MAP officers
and  employees.  A  recipient  of the MAP  stock  options  has the right to
purchase  Ashland  common  stock at a price and on terms to be specified by
the Committee or determined in some other manner under the plan.

Administration

                  The Committee  administers  the plan.  Mannie L. Jackson,
Patrick  F.  Noonan,  Kathleen Ligocki, T.M.  Solso and  Michael  J. Ward
presently serve on the Committee.


                                      -8-



Eligibility and Grant of MAP Stock Options

                  The MAP Executive Committee  recommended to the Committee
certain regular,  full-time or part-time employees of MAP to participate in
the plan.  The Committee  selected the MAP employees to receive an award of
MAP stock  options  under the plan.  The MAP stock  options  to which  this
prospectus  relates were granted to the recipients on each of September 17,
1998,  September  16,  1999,  September  21, 2000,  September  20, 2001 and
September 19, 2002. Under the notices of each grant, none of the rights and
obligations of the recipients,  including  under the vesting  provisions or
other  terms of the  notices of grant or the plan,  will be affected by the
transfer  of any of the  recipients  from  MAP to  Ashland  or from  MAP to
another unit of Marathon Oil  Corporation.  Under the notices of grant,  by
accepting the award of MAP stock options,  the recipients  agreed to remain
at MAP for a period  of at  least  one  year  from  the date of the  award,
although  this did not in any way confer from Old Ashland to any  recipient
any right to continue  employment  with MAP or affect any existing right of
MAP to terminate any recipient.  Ashland  similarly did not confer any such
right upon assuming the plan.

Annual Report to Optionees

                  Recipients  received,  on an annual basis,  a report from
Old Ashland as to the amount and status of their MAP stock options.

Exercise Price

                  Under the plan,  the  exercise  price for the  underlying
Ashland  common  stock  that will be issued  for each MAP stock  option was
fixed by the  Committee at the time the option was granted.  The  Committee
determined  that exercise price for the options to be the fair market value
per share of  Ashland's  common stock on the date of grant.  The  Committee
further  determined  fair market value to be the closing price per share of
Old  Ashland's  common  stock  on the  New  York  Stock  Exchange  ("NYSE")
composite  tape on the date of grant.  The price per share of Old Ashland's
common stock on the NYSE  composite tape on each of the dates of grant were
as  indicated  in  the  chart  below.  As a  result  of  the  transactions,
adjustments will be made to the exercise price pursuant to the terms of the
plan as discussed below under "Adjustments", so that the new exercise price
shall be as indicated in the chart below.

Acceptance of Awards

                  By  accepting  any award of MAP stock  options  under the
plan, each recipient was  conclusively  deemed to have indicated his or her
acceptance  and  ratification  of and consent to any action  that  Ashland,
Ashland's  board of directors or the  Committee may have taken with respect
to the plan,  including any amendment of the plan by the board of directors
or the  Committee.  The terms of this provision are also deemed to apply to
each personal  representative or beneficiary  claiming under or through the
recipient, as those individuals are defined under the plan.

Notice of Grant

                  Each MAP stock  option is  evidenced by a notice of grant
between the recipient and Old Ashland.  The notice of grant  contains those
terms and conditions that the Committee  determines and that are consistent
with the plan.

                                     9


Vesting

                  Unless the Committee determines otherwise, each MAP stock
option will provide that its recipient may not wholly or partially exercise
the option for a period of one year after the date of the  option's  grant.
In connection with the  transactions,  any outstanding  stock options which
were granted in 2001 or 2002 but were not vested  immediately prior to June
30, 2005 were subject to accelerated  vesting on June 30, 2005. The options
granted on September  17, 1998,  September 16, 1999 and September 21, 2000,
unless  otherwise  canceled or  terminated,  vested based on the  following
schedule:  50% of  the  MAP  stock  options  granted  vested  on the  first
anniversary  of the grant  date,  an  additional  25%  vested on the second
anniversary  of the grant  date and the  remaining  25% vested on the third
anniversary of the grant date.

Exercise of MAP Stock Options and Payment

                  A stock option may be exercised by written  notice to us.
The written notice must be consistent with the terms of the notice of grant
relating to the MAP stock option and must be  accompanied by payment of the
full exercise price for the underlying shares of our common stock which the
holder of the MAP stock option chooses to exercise.  The exercise price for
any shares  purchased  may be paid in cash,  in shares of our common  stock
previously  owned by the  holder,  partly in cash and  partly in our common
stock  or  in  such  other   consideration  as  shall   constitute   lawful
consideration for the issuance of common stock (including,  but not limited
to, a "cashless exercise"),  as the Committee, in its sole discretion,  may
determine.  There are no  restrictions  on the resale of the Ashland common
stock acquired as a result of the exercise of a MAP stock option.

                  In order to assure  compliance with the securities  laws,
during any time that the registration statement of which this prospectus is
a part is not effective,  the Committee may require  evidence of a type and
degree it considers  necessary to establish that the  underlying  shares of
common stock are being  purchased for  investment  only and not with a view
to,  or for  sale  in  connection  with,  a  distribution.  As used in this
context,  "distribution"  is  defined  under the  Securities  Act.  If this
prospectus  is not then part of an effective  registration  statement,  the
Committee may further require legends on the certificates  representing the
underlying shares.

                  As  a  condition  to  the   transfer  of  a   certificate
representing  those shares,  the  Committee may obtain those  agreements or
undertakings that it considers  necessary or advisable to assure compliance
with any provision of the plan or any law or regulation.

                  Each  stock  option   granted  on  September   17,  1998,
September 16, 1999 or September 21, 2000 which were  exercisable as of June
30, 2005,  and each stock option granted on September 20, 2001 or September
19, 2002,  including  the ones  subject to  accelerated  vesting  described
above,  which were not exercised  prior to June 30, 2005,  may be exercised
for  a  period  of  90  days  after  the  date  of   effectiveness  of  the
post-effective  amendments  to the  registration  statements  to which this
prospectus relates.

Cancellation of MAP Stock Option

                  The  Committee has the right in its sole  discretion  and
without the option  holder's  consent to cancel a MAP stock option  granted
under the plan,  whether  vested or not, at any time. If the Committee does
so, it will cause Ashland to pay the recipient  holding the canceled option
an amount  determined by using the  Black-Scholes  or some other  valuation
method  generally  accepted  and used by  nationally  recognized  executive
compensation consulting firms. The Committee will determine whether we make
the buyout  payments  under this provision in cash, in shares of our common
stock or partly in cash and partly in common stock. Buyout payments will be
made net of any applicable  foreign,  federal  (including  FICA),  state or
local withholding taxes.

Transferability

                  Unless our board of  directors or the  Committee  directs
otherwise,  the  rights  and  interest  of a  recipient  may not  wholly or
partially be assigned or  transferred  directly,  by operation of law or in
some other manner,  including but not limited to the following:  execution,
levy, garnishment,  attachment, pledge or bankruptcy. No recipient's rights
or interest under the plan will be assigned or  transferred  because of 
                                    10


any obligation or liability of that  recipient.  The sole exception to this
provision is that the  recipient's  rights and interest  under the plan may
pass by will or the laws of descent  and  distribution  in the event of the
recipient's death.

Reserve of Common Stock

                  Shares of our common stock to be issued upon the exercise
of MAP stock options will be from  authorized but unissued  shares.  If any
MAP stock option or a part of a MAP stock option expires,  terminates or is
canceled or surrendered for any reason without having been fully exercised,
the shares relating to the unexercised  portion of the MAP stock option may
again be subject to the grant of MAP stock options under the plan.

Term of the Plan

                  The plan became effective on September 17, 1998, the date
of the plan's  approval by Old Ashland's board of directors and was assumed
by Ashland on June 30, 2005, the closing date of the transactions, pursuant
to the  authority  granted  by  resolutions  of the board of  directors  of
Ashland  at a  special  meeting  held  on  June  29,  2005.  Following  the
transactions,  all of the MAP stock  options  will expire 90 days after the
effective  date of the  registration  statement  to which  this  prospectus
relates.

Termination of Employment

                  The plan provides that the Committee decides when and the
terms under  which a  recipient  (or his  beneficiaries  or legal  personal
representative, as the case may be, as those terms are defined in the plan)
who dies, becomes disabled or retires or leaves MAP employment may continue
to exercise vested MAP stock options. The Committee also decides the extent
to which unvested MAP stock options will vest for those  recipients.  Under
the notices of grant, in the event of a recipient's  retirement from MAP or
death or  disability  while  employed  by MAP,  Ashland or another  unit of
Marathon Oil  Corporation,  the MAP stock  option may be exercised  for the
number of shares which its recipient  could have acquired  under the option
immediately prior to the retirement, death or disability.

                  The plan provides  that if the  employment of a recipient
terminates before the end of the one year vesting period for the options or
any other  period  determined  by the  Committee,  then those  options will
immediately  terminate.  Under the  notices of grant,  a  recipient,  after
terminating  employment  from MAP,  Ashland or another unit of Marathon Oil
Corporation for a reason other than  retirement,  death or disability,  may
exercise  any  MAP  stock  option  until  the  earlier  of  30  days  after
termination  or the  expiration  date of the  option.  That  option  may be
exercised for the number of shares which the recipient  could have acquired
under the option immediately prior to termination.

                  Following the transactions, each of the MAP stock options
must be exercised prior to the expiration of the 90-day period beginning on
the effective date of the  registration  statement to which this prospectus
relates.

Adjustments

                  The kind of shares  that we may issue  under the plan and
the kind of shares  underlying the exercise price for any  outstanding  MAP
stock  options  is and  will be  automatically  adjusted  to  maintain  the
proportionate  interest of any  recipient  who received  MAP stock  options
before any of the following types of events: a stock split, stock dividend,
recapitalization,  merger,  consolidation,   reorganization,   combination,
exchange  of shares,  split-up,  split-off,  spin-off,  liquidation  or any
distribution to holders of our common stock other than cash dividends.  Any
adjustment  under this provision is conclusive and binding for all purposes
of the plan. As a result of the  transactions,  the  following  adjustments
shall be made:  (a) the number of shares  issuable  upon  exercise of a MAP
stock option  shall be  multiplied  by a  conversion  factor of 1.2129 (and
rounded down to the nearest  whole  share) and (b) the exercise  price of a
MAP stock  option  shall be divided by a  conversion  factor of 1.2129 (and
rounded up to the nearest whole cent).

                                    11


Amendment

                  Our board of directors or the  Committee  may at any time
terminate,  modify or amend the plan in those  respects it deems  advisable
and as permitted by law.

Type of Stock Option

                  The MAP stock options will be nonqualified  stock options
and will not be entitled to tax  treatment  as incentive  stock  options as
defined in Section 422 of the Internal Revenue Code of 1986, as amended.

Listing

                  The shares of our common stock  underlying  the MAP stock
options  have been  listed on the New York Stock  Exchange  and the Chicago
Stock Exchange.

FEDERAL INCOME TAX CONSEQUENCES

                  The following brief  description of the tax  consequences
of awards  under the plan is based on Federal tax laws  currently in effect
and does not  purport  to be a complete  description  of such  Federal  tax
consequences.

                  If  shares  are  issued  to  the  original  holder  of  a
nonqualified  option that is granted and exercised in  accordance  with the
plan, then:

     o    no income will be  recognized  by the holder at the time of grant
          of the option;

     o    upon  exercise  of the option the holder will  recognize  taxable
          ordinary  income  in an  amount  equal to the  excess of the fair
          market  value,  at the time of exercise,  of the shares  acquired
          over the option price;

     o    subject to the limitation described below, we will be entitled to
          a deduction at the same time and in the same amount as the holder
          has income under the preceding item; and

     o    upon  a  sale  of the  shares  acquired,  the  holder  will  have
          short-term or long-term capital gain or loss, as the case may be,
          in an amount equal to the difference  between the amount realized
          on the sale and the tax basis of the shares sold.

                  Assuming  that the  payment of the  option  price is made
entirely  in cash,  the tax basis of the shares will be equal to their fair
market value on the date of exercise,  but not less than the option  price,
and their  holding  period will begin on the day after the tax basis of the
shares is determined in this manner.

                  If the optionee uses previously  owned shares to exercise
an option in whole or in part, the transaction will not be considered to be
a taxable  disposition  of the  previously  owned shares.  The holder's tax
basis and holding  period of the  previously  owned  shares will be carried
over to the equivalent number of shares received on exercise. The tax basis
of the  additional  shares  received  upon exercise will be the fair market
value of the shares on the date of exercise but not less than the amount of
cash used in payment, and the holding period for the additional shares will
begin on the day after the tax basis of the  shares is  determined  in this
manner. In order to facilitate  recordkeeping by optionees,  when an option
is exercised with previously  owned shares,  we will deliver separate stock
certificates to the optionee  representing  the shares  surrendered and the
additional  shares to which the  optionee  is  entitled  as a result of the
exercise.

                  In  addition  to  the  Federal  income  tax  consequences
described above,  the acquisition,  ownership or disposition of a MAP stock
option or shares  acquired upon the exercise of a MAP stock option may have
tax consequences under various state or foreign laws that may be applicable
to certain option  holders.  Since these tax  consequences,  as well as the
Federal income tax  consequences  described  above, may vary from holder to
holder depending upon the particular facts and circumstances involved, each
holder  should  consult  his or her own tax  advisor  with  respect  to the
Federal  income tax  consequences  of the grant or  exercise of a MAP stock
option,  and also with  respect to any tax  consequences  under  

                                    12



applicable  state or foreign law.  Ashland will not withhold  more than the
statutorily required amounts for federal, state and local taxes.

                  To ensure  compliance  with  requirements  imposed by the
Internal  Revenue  Service,  we inform you that any tax advice contained in
the prospectus relating to the plan was not intended or written to be used,
and cannot be used, for the purpose of avoiding tax-related penalties under
the Internal Revenue Code.

PLAN OF DISTRIBUTION

                  Ashland  will offer the  underlying  shares of its common

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Sections   271B.8-500   through  580  of  the  Kentucky   Business
Corporation  Act  contain  detailed   provisions  for   indemnification  of
directors  and  officers  of  Kentucky   corporations   against  judgments,
penalties,  fines,  settlements and reasonable  expenses in connection with
litigation.  Under Kentucky law, the provisions of a company's articles and
by-laws may govern the indemnification of officers and directors in lieu of
the  indemnification  provided for by statute. We have elected to indemnify
our officers and directors pursuant to our Restated  Articles,  our By-laws
and by contract  rather than to have such  indemnification  governed by the
statutory provisions.

         Article X of the Restated Articles permits,  but does not require,
us to indemnify our directors, officers and employees to the fullest extent
permitted by law. Our By-laws require  indemnification  of our officers and
employees under certain circumstances. We have entered into indemnification
contracts  with 

                                    13


each of our directors  that require  indemnification  to the fullest extent
permitted by law, subject to certain exceptions and limitations.

         We have  purchased  insurance  which  insures  (subject to certain
terms and conditions,  exclusions and deductibles) us against certain costs
which  we  might  be  required  to pay by  way  of  indemnification  to our
directors   or   officers   under  our   Restated   Articles   or  By-laws,
indemnification  agreements or otherwise and protects individual  directors
and officers from certain losses for which they might not be indemnified by
us. In addition,  we have  purchased  insurance  which  provides  liability
coverage   (subject  to  certain  terms  and  conditions,   exclusions  and
deductibles)  for amounts which we, or the  fiduciaries  under our employee
benefit  plans,  which may include our  directors,  officers and employees,
might be required to pay as a result of a breach of fiduciary duty.

ITEM 17.  UNDERTAKINGS.

(A) The Registrant hereby undertakes:

                  (1) To file,  during any period in which  offers or sales
         are being made, a  post-effective  amendment to this  Registration
         Statement:

                           (i)  To  include  any  prospectus   required  by
                  Section 10(a)(3) of the Securities Act;

                           (ii) To reflect in the  prospectus  any facts or
                  events   arising   after  the   effective   date  of  the
                  Registration Statement (or the most recent post-effective
                  amendment   thereof)   which,   individually  or  in  the
                  aggregate,   represent  a   fundamental   change  in  the
                  information  set  forth  in the  Registration  Statement.
                  Notwithstanding  the foregoing,  any increase or decrease
                  in  volume of  securities  offered  (if the total  dollar
                  value of  securities  offered would not exceed that which
                  was  registered)  and any deviation  from the low or high
                  end  of  the  estimated  maximum  offering  range  may be
                  reflected  in the  form  of  prospectus  filed  with  the
                  Commission  pursuant to Rule 424(b) if, in the aggregate,
                  the changes in volume and price  represent no more than a
                  20% change in the maximum  aggregate  offering  price set
                  forth in the  "Calculation of Registration  Fee" table in
                  the effective registration statement; and

                           (iii) To include any material  information  with
                  respect  to  the  plan  of  distribution  not  previously
                  disclosed in the  registration  statement or any material
                  change to such information in the Registration Statement.

         Provided, however, that paragraphs (A)(l)(i) and (A)(1)(ii) do not
apply  if the  information  required  to be  included  in a  post-effective
amendment by those  paragraphs is contained in periodic  reports filed with
or furnished to the Commission by the Registrant  pursuant to section 13 or
section 15(d) of the Exchange Act that are incorporated by reference in the
Registration Statement.

                  (2) That,  for the purpose of  determining  any liability
         under  the  Securities  Act  of  1933,  each  such  post-effective
         amendment  shall  be  deemed  to be a new  registration  statement
         relating to the securities  offered  therein,  and the offering of
         such  securities  at that time  shall be deemed to be the  initial
         bona fide offering thereof.

                  (3)  To   remove   from   registration   by  means  of  a
         post-effective  amendment any of the securities  being  registered
         that remain unsold at the termination of the offering.

(B) The Registrant  hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's  annual
report  pursuant to section 13(a) or section 15(d) of the Exchange Act (and
each filing of an employee benefit plan's annual report pursuant to section
15(d)  of the  Exchange  Act)  that is  incorporated  by  reference  in the
Registration  Statement shall be deemed to be a new registration  statement
relating  to the  securities  offered  herein,  and  the  offering  of such
securities  at that  time  shall be  deemed  to be the  initial  bona  fide
offering thereof.

(C) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors,  officers and controlling persons of the
Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
Registrant  has been  advised  that in the opinion of the  Commission  such
indemnification is against public policy as expressed in the Securities Act
and  is,  therefore,   unenforceable.   In  the  event  that  a  claim  for
indemnification  against  such  liabilities  (other than the payment by the
Registrant  of  expenses  incurred  or  paid  by  a  director,  officer  or
controlling  person of the  Registrant  in the  successful  defense  of any
action,  suit or  proceeding)  is  asserted  by such  director,  officer or
controlling person in connection with the securities being registered,  the
Registrant  will,  unless in the opinion of its counsel the matter has been
settled  by  controlling  precedent,  submit  to  a  court  of  appropriate
jurisdiction  the question  whether such  indemnification  by it is against
public  policy,  as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

                                    15


                                 SIGNATURES

         Pursuant to the  requirements  of the  Securities Act of 1933, the
Registrant  certifies  that it has  reasonable  grounds to believe  that it
meets all of the  requirements  for filing on Form S-3 and has duly  caused
this  Post-Effective  Amendment  No. 1 to be  signed  on its  behalf by the
undersigned,  thereunto  duly  authorized,  in the  City of  Covington  and
Commonwealth of Kentucky on the 9th day of August, 2005.
