EXHIBIT 10.26

                  AMENDED AND RESTATED STOCK TRADING PLAN

     This Amended and Restated  Stock Trading Plan (the "Amended  Plan") is
being  adopted by Ashland  Inc.  (the  "Company")  to amend and restate the
Stock  Trading Plan (the "Plan") with Credit  Suisse  Securities  (USA) LLC
("Credit Suisse")  originally dated September 14, 2006. The Amended Plan is
intended to facilitate the  repurchase of its common stock (the  "Shares").
This Amended Plan is entered into on this 20th day of September,  2006, and
shall  terminate  on the  earlier of either the  purchase of a total of six
million  Shares under the Amended  Plan or March 31, 2007.  Notwithstanding
the  foregoing,  the Company may terminate this Amended Plan at any time by
providing written notice of termination prior to such termination date.

     To dispel an  inference  that the  Company is trading in the Shares on
the basis of, while using, when in possession of, or when aware of material
nonpublic information;  or that the trades in the Shares evidence Company's
knowledge of material  nonpublic  information,  or  information at variance
with Company  statements to investors;  Company has  determined to instruct
Credit Suisse to purchase a pre-determined amount of Shares pursuant to the
instructions set forth in Exhibit A.

     The Company hereby represents, warrants and acknowledges that:

     1. As of the date of this  Amended  Plan,  the Company is not aware of
any material nonpublic  information  regarding it and is not subject to any
legal,  regulatory or contractual  restriction  or  undertaking  that would
prevent  Credit  Suisse  from  acting  upon the  instructions  set forth in
Exhibit A;

     2. The Company is entering  into this  Amended  Plan in good faith and
not as part of any scheme to evade the  prohibitions of Rule 10b5-1 adopted
under the Securities Exchange Act of 1934, as amended (the "Exchange Act");

     3. The  Company  has not entered  into,  and will not enter into,  any
corresponding  or  hedging  transaction  or  position  with  respect to the
Shares;

     4. Credit  Suisse may make a market in the Shares and will continue to
engage in market-making  activities while executing  transactions on behalf
of the Company pursuant to the Amended Plan;

     5. The Company may not  discuss  with Credit  Suisse the timing of the
trading  in  the  Shares  (other  than  to  confirm  this  Amended   Plan's
instructions set forth in Exhibit A and describe them if necessary);

     6. The Company will execute all purchases pursuant to Rule 10b-18 from
or  through  only one broker or dealer on any  single  day,  subject to the
exemption set forth in Rule 10b-18(b)(1)(i);

     7. Payment for shares  purchased  pursuant to this letter will be made
in accordance with normal settlement procedures; and

     8. It is the intent of the Company  that this Amended Plan comply with
the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act and this
Amended Plan shall be interpreted to comply with Rule 10b5-1(c).

     Credit Suisse agrees that:

     1.  Shares will be  purchased  in  accordance  with Rule 10b-18 of the
Exchange Act;

     2. It shall make such  repurchases in accordance with the instructions
set forth on Exhibit A. However, the total number of Shares to be purchased
on any day shall not exceed the then applicable  volume  limitation of Rule
10b-18 under the Exchange Act.

                                     1


     3. Purchases made by Credit Suisse shall be made in the open market as
per instructions provided by the Company.

     4. Credit Suisse shall provide price and volume information daily with
respect to each purchase  executed on the Company's behalf as well as other
market data that the Company may reasonably request.

     Company  authorizes and directs Company's insider trading personnel to
take all  necessary  steps to effect  the  instructions  described  in this
Amended  Plan.  This  Amended  Plan shall be governed by and  construed  in
accordance  with the laws of the State of New York,  without regard to such
State's conflict of laws rules.

                                                                  EXHIBIT A

                         SHARE TRADING INSTRUCTIONS
          for Ashland Inc. Amended and Restated Stock Trading Plan
                          Dated September 20, 2006


     Repurchases  of  Ashland's  Shares  pursuant to the Amended Plan shall
commence  on  October  2, 2006 and  Credit  Suisse  shall  comply  with the
instructions set forth herein each day on which Ashland's Shares are traded
on the New York Stock Exchange until the Amended Plan is terminated.

     Ashland's  Board of Directors has declared that a special  dividend of
$10.20 per share be paid on October 25, 2006, to common stock  shareholders
of record on October 10, 2006 (the  "Special  Dividend").  Purchases  under
this Amended  Plan prior to the  "ex-dividend"  trading  date  (October 26,
2006) are to be made as follows:

     PRICE RANGE                     DAILY REPURCHASE AMOUNT (SHARES)*
     Above $72                                     50,000
     $70.01 - $72.00                               65,000
     $68.01 - $70.00                               90,000
     $66.01 - $68.00                              112,500
     $64.01 - $66.00                              125,000
     $62.01 - $64.00                              150,000
     $60.01 - $62.00                              185,000
     $60 and Below                                250,000

     For purchases under this Amended Plan made on an "ex-dividend"  basis,
the "Price Range" above shall be adjusted  downward to directly reflect the
per share amount of the Special Dividend as follows:

     PRICE RANGE                     DAILY REPURCHASE AMOUNT (SHARES)*
     Above $61.80                                  50,000
     $59.81 - $61.80                               65,000
     $57.81 - $59.80                               90,000
     $55.81 - $57.80                              112,500
     $53.81 - $55.80                              125,000
     $51.81 - $53.80                              150,000
     $49.81 - $51.80                              185,000
     $49.80 and Below                             250,000

*All  purchases  under this  Amended  Plan are intended to be executed in a
manner that permits the "safe harbor" from  liability for  manipulation  of
the price of a  security  under the  Securities  Exchange  Act of 1934 (the
"Exchange  Act") as  specifically  set forth in Exchange Act Rule 10b-18 to
apply.  As such,  "Daily  Repurchase  Amount"  shall mean the lesser of the
amount of Shares  referenced in this column or the maximum amount of Shares
which are permitted within the safe harbor provisions of Rule 10b-18.

                                     3


     If the price stays within a particular Price Range during a given day,
Credit Suisse shall purchase the Daily Repurchase  Amount in that range for
that day.

     If the price drops into a lower Price Range during a given day, Credit
Suisse shall increase  purchases to buy up to the Daily  Repurchase  Amount
for the lower  price band.  However,  if the price drops by more than $2.50
per share  during a given day,  Credit  Suisse  shall  purchase the maximum
number of shares which are permitted  within the safe harbor  provisions of
Rule 10b-18.

     If the price  increases to a higher Price Range during a given day and
Credit Suisse has already exceeded the Daily Repurchase Amount in the Price
Range for the higher  Price  Range,  then Credit  Suisse shall not make any
additional  purchases  within that Price  Range.  If Credit  Suisse has not
exceeded the Daily Repurchase Amount in the higher Price Range, then Credit
Suisse shall continue to buy shares in the range up to the Daily Repurchase
Amount in the higher Price Range.
