PART I - REGISTRANT INFORMATION
--------------------------------

Full Name of Registrant:  MERGE TECHNOLOGIES INCORPORATED

Former Name, if Applicable:  NA

Address of Principal Executive Office (Street and Number):  6737 West Washington
Street, Suite 2250

City, State and Zip Code:  Milwaukee, Wisconsin  53214


PART II - RULES 12b-25(b) AND (c)
----------------------------------

If the subject report could not be filed without unreasonable effort or expense
and the Registrant seeks relief pursuant to Rule 12b-25(b), the following
should be completed. (Check box if appropriate) [   ]

	(a)	The reasons described in reasonable detail in Part III of this
                form could not be eliminated without unreasonable effort or
                expense;

	(b)	The subject annual report, semi-annual report, transition report
                on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or
                portion thereof, will be filed on or before the fifteenth
                calendar day following the prescribed due date; or the subject
                quarterly report or transition report on Form 10-Q or subject
                distribution report on Form D, or portion thereof, will be
		filed on or before the fifth calendar day following the

PART III - NARRATIVE
---------------------

State below in reasonable detail the reasons why the Form 10-K, 20-F, 11-K,
10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not
be filed within the prescribed time period.

We have not completed our financial statements for the year ended December 31,
2005.  Accordingly, we did not file our Form 10-K on March 16, 2006 and do not
expect to file our Form 10-K by March 31, 2006, so we did not request a 15-day
extension permitted by Rule 12b-25 under the Securities Act of 1934, as
amended.  The reason for the delay relates to revenue recognition and tax
accounting matters relating to the merger of the Company and Cedara Software
Corp. in June 2005.  An additional reason for the delay has been the
investigation of anonymous complaints received by us.  In accordance with
our policies, the Audit Committee of the Board of Directors is conducting
a review of each of the communications.  The Audit Committee has retained
independent advisors to assist in those reviews.

In addition:

	- We have not completed our assessment of internal control over
	  financial reporting.  Based upon our work to date, we anticipate
	  that we will report material weaknesses in our internal control over
	  financial reporting.

	- Our registration statement on Form S-3 relating to issuance of our
	  common stock upon exchange of exchangeable shares of Merge/Cedara
	  ExchangeCo Ltd is hereby suspended, and no shares of Merge's Common
	  Stock may be issued for exchangeable shares until further notice.


PART IV - OTHER INFORMATION
----------------------------

(1)	Name and telephone number of person to contact in regard to this
	notification:

                   Scott T. Veech     (414)            977-4264
		 -----------------  -----------  ---------------------
                      (Name)        (Area Code)   (Telephone Number)

(2)	Have all other periodic reports required under Section 13 or 15(d) of
	the Securities and Exchange Act of 1934 or Section 30 of the Investment
        Company Act of 1940 during the preceding twelve (12) months (or for such
        shorter period that the Registrant was required to file such reports)
        been filed?  If answer is no, identify report(s).  [ X ] Yes [   ] No

(3)	Is it anticipated that any significant change in results of operations
        from the corresponding period for the last fiscal year will be
	reflected by the earnings statements to be included in the subject
	report or portion thereof?  [ X ] Yes [   ] No

If so, attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

On March 16, 2006, our management and the Audit Committee of our Board of
Directors concluded that its previously issued financial statements for the
quarters ended June 30, 2005, and September 30, 2005, as contained in Merge's
Quarterly Reports on Form 10-Q for the quarters ended June 30, 2005, and
September 30, 2005, should no longer be relied upon.

We have determined that approximately $3.8 million of additional tax
liability needs to be recorded as of June 30, 2005, relating to the merger
with Cedara Software Corp., with an approximate $2.5 million increase to
goodwill and an approximate $1.3 million increase to income tax expense for
the quarter ended June 30, 2005.  We have determined that we will need to
make an adjustment to reduce revenue by approximately $800,000 because we
were unable to establish Vendor Specific Objective Evidence ("VSOE") of fair
value primarily for maintenance on certain contracts related to the direct
business associated with our merger.  Such amount will be recorded as a
reduction in net sales and an increase in deferred revenue.  In addition, we
determined that we need to make an adjustment of approximately $200,000
relating to the accounting for a single customer credit.

Accordingly, we will need to make a downward adjustment of net sales of
approximately $500,000 in the second quarter and an additional $500,000 in
the third quarter.  We have not yet completed our review, and there may be
additional adjustments.





The Audit Committee has discussed these matters with our independent
accountants, KPMG LLP.  KPMG has not yet completed its audit for the year
ended December 31, 2005.

Further, information relating to non-reliance on the previously issued
financial statements may be found in our Current Report on Form 8-K being
filed today with the Securities and Exchange Commission.
