                  POWER OF ATTORNEY: DISTRIBUTION AGREEMENT



KNOW ALL MEN BY THESE PRESENTS:

                  1.       Subject to paragraph 7 below:

                  a.       That Pharmacia Corporation, a corporation

("Pharmacia"), has made, constituted and appointed and by these presents
  ---------
does make, constitute and appoint, Monsanto Company, a corporation organized

                                                       ------------
true and lawful agent and attorney, for Pharmacia and in Pharmacia's name,
place and stead, for all purposes with respect to Pharmacia's rights, duties
and obligations under the Distribution Agreement, dated as of September 1,
1997, between Pharmacia and Solutia Inc., as amended by that Amendment to
Distribution Agreement of even date herewith among Pharmacia, Solutia and
New Monsanto (collectively, the "Distribution Agreement"); and its attorney
                                 ----------------------
shall have full power and authorization to take all action with respect to
the Distribution Agreement as Pharmacia can take and which said attorney,
acting through its officers or their delegates, who in each case, acting
alone, in his or her sole discretion, think best; hereby giving and granting
to Pharmacia's said attorney full power and authority to do and perform all
and every act and thing whatsoever necessary to be done in the premises as

ratifying and confirming all that its said attorney may do pursuant to this
power.

                  b.       Pharmacia hereby gives and grants to its said
attorney from and after the date hereof, full power and authority to do and
perform all and every act and thing whatsoever necessary to be done in the

ratifies and confirms all that its said attorney may do pursuant to this
power.

                  c.       Pharmacia hereby acknowledges that this power is
coupled with an interest and hereby directs that, to the extent authorized
or permitted by applicable law, this power of attorney shall not be affected
by any merger, reverse merger, consolidation or Possible Disposition or
other change in ownership of Pharmacia or New Monsanto. It is Pharmacia's
intent that the authority conferred hereby shall be exercisable
notwithstanding such corporate changes and that this power of attorney
shall, if permitted by applicable law or applicable contract, be

decision, or otherwise), then Pharmacia directs that the foregoing
provisions shall thereafter become applicable.

                  2.       Notwithstanding paragraph 6 below, all persons
dealing with Pharmacia's said attorney shall be protected in relying upon a

persons claiming under it everything which its attorney shall do or cause to
be done pursuant hereto shall be valid and effectual in favor of any person

applicable law or if New Monsanto desires for any reason to do so, an
executed copy of this Power of Attorney shall be filed for record with any
Governmental Authority or such other place as required by law or where New
Monsanto thinks best. Pharmacia authorizes New Monsanto to make all such
filings.

                  3.       Pharmacia hereby further authorizes and empowers
its said attorney to substitute and appoint in the place and stead of its
said attorney, or to employ agents or sub-agents as New Monsanto thinks
best, one or more attorney or attorneys to exercise for Pharmacia as its
