ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

              Pursuant to the terms of an Agreement and Plan of Merger dated
February 15, 2000, as amended (the "Merger Agreement"), among the Issuer, KTC
Acquisition Corp. ("Sub") and Advanced Machine Vision Corporation ("AMVC"), all
of the Series B Preferred Stock of AMVC held by FMC Corporation, a Delaware
corporation and owner of approximately 83% of the common stock of Technologies
("Parent"), converted into 119,106 shares of the Issuer's Series C Preferred
Stock, par value $20 per share (the "Series C Preferred Stock"), and warrants to
purchase 29,776 shares of Common Stock of the Issuer at an exercise price of $15
per share (the "Series C Warrants"). Each share of Series C Preferred Stock is
convertible at any time into 1 2/3 shares of Common Stock of the Issuer. In
addition, pursuant to an Agreement dated April 24, 2000 (the "Key Agreement")
among Parent, the Issuer, Sub and AMVC, concurrently with the consummation of
the transactions contemplated by the Merger Agreement, an option held by Parent
to purchase common stock of AMVC converted into an option (the "FMC Option"),
exercisable for $2,520,000, to purchase 210,000 shares of the Issuer's Series B
Preferred Stock, par value $10 per share (the "Series B Preferred Stock"), and
warrants to purchase 52,500 shares of Common Stock of the Issuer at $15 per
share (the "Series B Warrants" and, together with the Series C Warrants, the
"Warrants"). Each share of Series B Preferred Stock is convertible at any time
into 2/3 of a share of Common Stock of the Issuer. The FMC Option may be
exercised at any time (in all or in part) by Technologies until October 14,
2003, at which time the FMC Option terminates. The source of funds to be used in
connection with the exercise of the FMC Option and the Warrants will be
Technologies' working capital.

ITEM 4. PURPOSE OF TRANSACTION.

         Parent acquired the Series B Preferred Stock and the Series B Warrants
pursuant to the Merger Agreement. Parent acquired the FMC Option pursuant to the
Key Agreement. Parent subsequently transferred all of its right, title and
interest in and to the Series B Preferred Stock, the Series B Warrants and the
FMC Option to Technologies. On August 3, 2001, Technologies exercised its
redemption rights with respect to its 119,106 shares of Series C Preferred Stock
and warrants to purchase 29,776 shares of Common Stock, resulting in expected
proceeds of $2,679,880.

         Technologies currently intends to review its investment in the Issuer
periodically and, depending on such review and factors including market
conditions and share prices, the Issuer's business prospects and technology,
future developments, applicable legal requirements and other factors that the

                                       -8-



management of Technologies may deem material to its investment decision,
Technologies may seek to acquire additional securities of the Issuer or sell
securities of the Issuer from time to time in the open market, in negotiated
transactions, in transactions with the Issuer pursuant to the terms of the
securities or otherwise or by any other permissible means. Except as set forth
above, Technologies has no present plans or proposals which may be related to or
would result in:

         (a)  The acquisition by any person of additional securities of the
Issuer, or the disposition of securities of the Issuer;

         (b)  An extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Issuer or any of its subsidiaries;

         (c)  A sale or transfer of a material amount of assets of the Issuer or
any of its subsidiaries;

         (d)  Any change in the present board of directors or management of the
Issuer, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the issuer's board of directors;

         (e)  Any material change in the present capitalization or dividend
policy of the Issuer;

         (f)  Any other material change in the Issuer's business or corporate
structure;

         (g)  Changes in the Issuer's charter, bylaws or instruments
corresponding thereto or other actions which may impede the acquisition of
control of the Issuer by any person;

         (h)  Causing a class of securities of the issuer to be delisted from a
national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association;

         (i)  A class of equity securities of the Issuer becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Act; or

         (j)  Any action similar to any of those enumerated above.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

         Technologies beneficially owns 192,500 shares of Common Stock,
constituting 3.9% of the outstanding shares of the Issuer's Common Stock as of
July 31, 2001. Based upon filings by the Issuer with the Securities and Exchange
Commission and in accordance with Rule 13d-3 under the Securities Exchange Act
of 1934, as amended, Technologies beneficially owns (i) 210,000 shares of Series
B Preferred Stock, constituting 13.6% of the outstanding shares of the Series B
Preferred Stock and (ii) Warrants to purchase 52,500 shares of Common Stock,
constituting 31.6% of the outstanding Warrants. To the best knowledge of FMC,
none of the other persons listed in Item 2 hereof owns any securities of the
Issuer.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
          WITH RESPECT TO SECURITIES OF THE ISSUER.

         As described in Items 3 and 4, Parent acquired the Series C Preferred
Stock and the Series C Warrants pursuant to the Merger Agreement. Parent
acquired the FMC Option pursuant to the Key Agreement. Parent subsequently
transferred all of its right, title and interest in and to the Series B
Preferred Stock, the Series B Warrants and the FMC Option to Technologies.

                                       -9-



         Series C Preferred Stock. Pursuant to the Certificate of Designation
         ------------------------
for the Series C Preferred Stock, Technologies has a put right requiring the
Issuer to purchase at any time any or all of its Series C Preferred Stock at the
redemption price of $20.00. On August 3, 2001, Technologies exercised its
redemption rights with respect to its 119,106 shares of Series C Preferred
Stock, resulting in expected proceeds of $2,382,120.

         Series B Preferred Stock. Pursuant to the Certificate of Designation
         ------------------------
for the Series B Preferred Stock, each share of Series B Preferred Stock may be
converted into 2/3 of a share of Common Stock of the Issuer in two instances:

         -    by the holders of such shares at any time; or
         -    by the Issuer upon a merger, consolidation, share exchange or sale
              of substantially all of its assets.

         In the event of any liquidation, dissolution or winding up of the
Issuer, the holders of Series B Preferred Stock are entitled to a payment of
$10.00 per share, plus all accrued but unpaid dividends before any amount is
distributed to holders of Common Stock. If the assets are insufficient to permit
this payment to the holders of Series B Preferred Stock, then the entire assets
available for distribution to the holders of capital stock shall be distributed
ratably among the holders of Series B Preferred Stock and Series C Preferred
Stock.

         The holders of Series B Preferred Stock are entitled to vote on all
matters. Series B Preferred Stock holders vote the number of whole shares of
Common Stock into which the holder's Series B Preferred Stock could be
converted.

         The Issuer must redeem the Series C Preferred Stock for $10.00 per
share, plus accrued but unpaid dividends on the fifth anniversary of the first
day shares of Series B Preferred Stock were issued. The redemption date may be
accelerated if the average closing price of the Issuer's Common Stock, as listed
on the Nasdaq National Market, is $15.00 or more for thirty consecutive trading
days. In addition, holders of Series B Preferred Stock have a put right
requiring the Issuer to purchase at any time after the second anniversary of the
first date shares of Series B Preferred Stock were issued any or all of their
Series B Preferred Stock at the redemption price of $10.00.

         Warrants. The Series C Warrants entitle Technologies to purchase at any
         --------
time, for a period of five years, 29,776 shares of Common Stock at $15.00 per
share, subject to adjustment.

         Prior to the expiration date of the Series C Warrants, Technologies may
require the Issuer to redeem the Series C Warrants for cash at a price equal to
$10.00 for each whole share of Common Stock that may be purchased under the
Series C Warrants. Technologies does not have the right to vote or participate
in any other matters as a shareholder pursuant to the Warrants. On August 3,
2001, Technologies exercised its redemption rights with respect to its warrants
to purchase 29,776 shares of Common Stock, resulting in expected proceeds of
$297,760.

         The Series B Warrants have identical terms to the Series C Warrants,
but will not be issued until such time, if any, that Technologies exercises the
FMC Option.

         General. The Key Agreement, the Key Option, the forms of the
         -------
Certificate of Designation for the Series B Preferred Stock and the Series C
Preferred Stock and the form of the Warrants are attached as exhibits hereto and
the descriptions of the foregoing contained herein are qualified in their
