This Amendment No. 2 (this "Amendment No. 2") amends the Amendment No. 1 to
Schedule 13D filed on August 24, 2006 (the "Amendment No. 1") by Mr. Larry N.
Feinberg ("Mr. Feinberg"). This Amendment No. 2 relates to the Common Stock, par
value $0.01 per share, of Merge Technologies Incorporated, a Wisconsin
corporation (the "Company"). Unless the context otherwise requires, references
herein to the "Common Stock" are to such Common Stock of the Company. This
Amendment No. 2 is being filed to report a change in beneficial ownership in
excess of 1% of the total amount of Common Stock outstanding and to report
beneficial ownership of less than 5% of the total outstanding Common Stock.
Capitalized terms used but not defined herein have the meaning ascribed thereto
in Amendment No. 1.

Item 3.   Source and Amount of Funds or Other Consideration.

     Item 3 of Amendment No. 1 is hereby amended by the deletion of the text
thereof in its entirety and its replacement with the following:

     As of the date hereof, Mr. Feinberg may be deemed to beneficially own
1,401,475 shares of the Company's Common Stock (the "Shares"), consisting of
1,401,475 shares of Common Stock. The Shares are held by the Funds. Mr. Feinberg
has investment discretion over the activities of the Funds through Oracle
Associates and the Investment Manager. The Shares were purchased for an
aggregate purchase price of $16,115,169.26. The funds for the purchase of the
Shares held by the Funds came from capital contributions to the Funds by the
investors in such Funds. The Shares were purchased through margin accounts
maintained with UBS which may extend margin credit to the Reporting Person and
other persons under his investment discretion as and when required to open or
carry positions in these margin accounts, subject to applicable Federal margin
regulations, stock exchange rules and the firm's credit policies. In such
instances, the positions held in the margin accounts are pledged as collateral
security for the repayment of debit balances in the accounts.




Item 5.   Interest in Securities of the Issuer.

     Item 5 of Amendment No. 1 is hereby amended by the deletion of the text
thereof in its entirety and its replacement with the following:

(a) & (b) Ownership and power over disposition:
          ------------------------------------

A. Mr. Feinberg
   ------------

     (a) Amount beneficially owned: 1,401,475

     (b) Percent of class: 4.7% The percentages used herein and in the rest of
this Amendment No. 2 are calculated based upon a total of 29,278,564 outstanding
shares of Common Stock issued and outstanding as of November 2, 2006 as reported
in the Company's Report on Form 10-Q for the quarterly period ended September
30, 2006. The warrants to purchase shares of Common Stock previously owned by
Mr. Feinberg, as reported in Amendment No. 1, have expired unexercised.

     Number of shares as to which such person has:

     (i)    Sole power to vote or direct the vote:  0
     (ii)   Shared power to vote or direct the vote: 1,401,475
     (iii)  Sole power to dispose or direct the disposition: 0
     (iv)   Shared power to dispose or direct the disposition:  1,401,475

     (c) The transactions in the shares of the Common Stock that may be deemed
to be beneficially owned by the Reporting Person during the past 60 days are set
forth on Exhibit 99.1 attached hereto. All such transactions were effected in
open market purchases.

     (d) The Reporting Person expressly disclaims beneficial ownership of such
shares of Common Stock except to the extent otherwise reported herein. Other
than as set forth herein, no other person is known to have the right to receive
or the power to direct the receipt of dividends from, and proceeds from the sale
of, securities reported in this Amendment No. 2 which constitute more than five
percent of the total outstanding Common Stock.

     (e) Not applicable.
