               ADAC LABORATORIES TO RESTATE FISCAL YEARS 1996-1998


Milpitas, California, December 29, 1998 - ADAC Laboratories (Nasdaq: ADAC)
announced today that its financial results for fiscal years 1996, 1997 and 1998
will be restated. This restatement is a result of an extensive ongoing review by
the Company with the assistance of Pricewaterhouse Coopers (PwC) of its
accounting principles and their historic application. The Company did not file
its Annual Report on Form 10-K yesterday and has applied for an extension.

As part of this restatement, the Company will adjust the timing of certain
revenues over the 1996-1998 period. The primary impact of these adjustments will
be to move revenues forward into adjacent future periods. Substantially all of
the transactions relating to these revenues have been completed and the
associated revenues have been or will shortly be recognized. In addition,
certain expenses will be adjusted and re-allocated throughout the period.

Based on the review to date, the Company believes that the net effect of these
adjustments will have a material adverse impact on the Company's fiscal 1996 and
1997 financial results but are not expected to have a material impact on its
previously released fiscal 1998 revenue, although the effect on revenue in
individual quarters may be material. In addition, management believes that net
income for 1998 may be somewhat lower or somewhat higher than previously
reported, depending on the outcome of the ongoing review. Additionally, the
Company believes these accounting changes will not have a material impact on the
Company's future business prospects.

After the issuance of the Company's earnings release in early November, several
issues concerning accounting policies and practices were raised. Thereafter, the
Company, working with PwC, undertook an extensive review of these issues,
particularly with respect to the accounting treatment of various one-time
charges taken by the Company as well as the appropriateness of certain expense
and revenue recognition practices that the Company had followed in recent years.
Following the review, the Company will apply different revenue recognition
guidelines than it has followed, change the accounting for certain transactions
and adjust certain expense items.

The Company's competitive position continues to be very strong, with leading
product portfolios in each of its three major businesses. In addition, ADAC has
had record customer order volumes over the course of the last two years. With
the release of several new product lines in the current quarter, it has
significantly further improved its competitive position entering fiscal 1999.
The Company remains confident in its long-term growth prospects.
