provisions of Section 7 and Section 13.

                  Section 16.  This Amendment may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                  Section 17.  Any provision of this Amendment which is
prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof. Any
such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.
Each party acknowledges that money damages would be an inadequate remedy for
any breach of the provisions of this Amendment and agrees that the
obligations of the parties hereunder shall be specifically enforceable.

                  POWER OF ATTORNEY: DISTRIBUTION AGREEMENT



KNOW ALL MEN BY THESE PRESENTS:

                  1.       Subject to paragraph 7 below:

                  a.       That Pharmacia Corporation, a corporation
organized and existing under the laws of the State of Delaware
("Pharmacia"), has made, constituted and appointed and by these presents
  ---------
does make, constitute and appoint, Monsanto Company, a corporation organized
and existing under the laws of the State of Delaware ("New Monsanto"), its
                                                       ------------
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
fully to all intents and purposes as Pharmacia might or could do, hereby
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
premises, in order fully to carry out and effectuate the authority herein
granted, as fully to all intents and purposes as Pharmacia might or could do
if acting through its own officers or delegates, and Pharmacia hereby
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
irrevocable. In the event applicable law in effect at or any time after the
execution of this instrument does not authorize or permit the foregoing
direction to be effective, and if at






any later date, applicable law changes (whether by amendment, court
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
copy of this instrument and shall be protected in relying upon the written
certificate of New Monsanto as to the identity and authority of its officers
and their delegates, and/or as to whether any of the persons authorized to
act hereunder is unavailable so to act, so as to authorize some other person
to act hereunder, and Pharmacia hereby declares that as against it and all
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
claiming the benefit hereof who at the time of the doing thereof shall have
relied upon any such certification made by New Monsanto. If required by
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
attorney or attorneys any and all of the powers and authorities hereby
conferred; and to revoke such appointment or appointments from time to time,

                  d.       Pharmacia shall have the right, in its sole
discretion, to revoke this Power of Attorney, by delivering written notice
to New Monsanto upon any breach by New Monsanto of its commitments, duties
or obligations under any of (i) this Power of Attorney, (ii) the Distribution
Agreement, as amended by the Amendment to the Distribution Agreement, or
