                                                                   June 13, 1995
 
To Our Stockholders:
 
     Moorco International Inc. has entered into a merger agreement with FMC
Corporation which provides for a wholly owned subsidiary of FMC to amend its
existing cash tender offer to increase the price offered for all outstanding
common shares of Moorco from $20.00 per share to $28.00 per share. The FMC
tender offer will be followed by a merger of the FMC subsidiary with Moorco. In
the merger, each Moorco share which is not purchased in the tender offer will be
converted into $28.00 in cash.
 
     THE BOARD OF DIRECTORS OF MOORCO HAS UNANIMOUSLY APPROVED THE TRANSACTION
WITH FMC, HAS DETERMINED THAT THE AMENDED OFFER AND THE MERGER ARE FAIR TO AND
IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND RECOMMENDS THAT
STOCKHOLDERS ACCEPT THE $28.00 AMENDED OFFER AND TENDER THEIR SHARES. The
amended offer is scheduled to expire at midnight on Monday, June 26, 1995.
 
     Enclosed is FMC's Supplement dated June 13, 1995 to its Offer to Purchase
dated May 5, 1995, and a revised Letter of Transmittal. These documents set
forth the amended terms and conditions of the FMC tender offer and contain other
important information relating to the tender offer and the merger. These
documents also provide instructions as to how to tender your Moorco shares. Also
attached is a copy of an amendment to Moorco's Schedule 14D-9, as filed with the
Securities and Exchange Commission. The attached Schedule 14D-9 describes in
more detail the reasons for your Board's decision. Among other things, the Board
considered the opinion of Salomon Brothers Inc, its financial advisor, that the
consideration to be received by Moorco stockholders (other than FMC) pursuant to
the tender offer and the merger is fair to such stockholders from a financial
point of view. We urge you to read all of these materials carefully.
 
     Your Board of Directors, the management and employees of Moorco thank you
sincerely for your loyal support.
 
                      On behalf of the Board of Directors,
