FOR IMMEDIATE RELEASE

WINMARK CORPORATION ANNOUNCES

CHANGE IN ACCOUNTING TREATMENT FOR INVESTMENT IN TOMSTEN, INC.

Minneapolis, MN (February 11, 2008)  —  Winmark Corporation (Nasdaq: WINA) announced today that during the fourth quarter, it changed the accounting treatment for its investment in Tomsten, Inc. (d/b/a Archiver’s).  The accounting change was made as a result of (i) the cancellation of a preexisting voting agreement between Tomsten, Inc. and Winmark that gave certain Tomsten officers the right to vote Winmark’s shares and (ii) the addition of John L. Morgan (Winmark’s Chairman and Chief Executive Officer) to the board of Tomsten, Inc.  Previously the company utilized the cost method of accounting.  The impact to Winmark’s financial statements include:

·A $2.0 million reduction to Winmark’s investment in Archiver’s.  As of December 29, 2007, the book value of Winmark’s investment was $5.5 million down from $7.5 million at the end of the third quarter.  This reduction reflects Winmark’s pro rata share of Archiver’s losses since August 2002 (the date of Winmark’s initial investment);

·A reduction of Winmark’s equity of $1.8 million;

·An increase to Winmark’s deferred tax assets of $0.2 million; and

·A reduction of pre-tax income of $0.36 million and $0.13 million for the years ended December 29, 2007 and December 30, 2006 respectively.  The charges, net of tax, approximate $0.04 per share in 2007 and $0.01 per share in 2006.

On an ongoing basis Winmark will continue to record its pro rata share of Archiver’s earnings and/or losses.

Winmark will announce its year-end results on February 22, 2008.
