EXHIBIT 10.1

                             STOCK TRADING PLAN

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

     5. The Company may not  discuss  with Credit  Suisse the timing of the
trading in the Shares (other than to confirm this 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 Plan  comply  with the
requirements  of Rule  10b5-1(c)(1)(i)(B)  under the  Exchange Act and this
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.

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

                                     1


     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 Plan.
This 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. Stock Trading Plan
                          Dated September 14, 2006


     Repurchases of Ashland's Shares pursuant to the Plan shall commence on
September 25, 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 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 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 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.  By way of example only, assuming the
Special  Dividend  is exactly  $10.00  per  share,  the above grid would be
adjusted "ex-dividend" to the following:

     PRICE RANGE                     DAILY REPURCHASE AMOUNT (SHARES)*
     Above $62                                     50,000
     $60.01 - $62.00                               65,000
     $58.01 - $60.00                               90,000
     $56.01 - $58.00                              112,500
     $54.01 - $56.00                              125,000
     $52.01 - $54.00                              150,000
     $50.01 - $52.00                              185,000
     $50 and Below                                250,000

*All purchases under this 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.
