ITEM 4.  DESCRIPTION OF SECURITIES.

     Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The validity of the common stock  offered  hereby has been passed upon
by David L. Hausrath,  Esq.,  Senior Vice  President,  General  Counsel and
Secretary of Ashland.  Mr. Hausrath owns beneficially  94,805 shares of our
common   stock   (including   common  stock  units  held  in  our  deferred
compensation plan).

     The  consolidated   financial   statements  and  schedule  of  Ashland
appearing  in  Ashland's  Annual  Report  (Form  10-K)  for the year  ended
September   30,  2005,   and  Ashland   management's   assessment   of  the
effectiveness of internal control over financial  reporting as of September
30, 2005 included therein, have been audited by Ernst & Young LLP ("Ernst &
Young"),  Independent  Registered  Public  Accounting Firm, as set forth in
their  reports  thereon  included   therein  and  incorporated   herein  by
reference.   Such  consolidated   financial  statements  and  schedule  and
management's  assessment are, and audited consolidated financial statements
and schedule and  management's  assessment  to be included in  subsequently
filed documents will be,  incorporated  herein in reliance upon the reports
of Ernst & Young  pertaining to such financial  statements and management's
assessment (to the extent  covered by consents  filed with the  Commission)
given  upon  the  authority  of such  firm as  experts  in  accounting  and
auditing.

ITEM 6.  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 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 7.  EXEMPTION FROM REGISTRATION CLAIMED.

     Not applicable.

ITEM 9.  UNDERTAKINGS.

     (A)  Ashland 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 Ashland 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 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.

                                     4

     (B) Ashland hereby  undertakes  that, for purposes of determining  any
liability under the Securities Act, each filing of Ashland'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  therein,  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 Ashland  pursuant to the  foregoing  provisions,  or  otherwise,
Ashland  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 Ashland
of expenses incurred or paid by a director,  officer or controlling  person
of Ashland 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, Ashland 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.


                                     5
