ITEM 4.02 NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED
          AUDIT REPORT OR COMPLETED INTERIM REVIEW.

On December 15, 2005, the Company determined that the Company's financial
statements for the years ended December 31, 2004, 2003 and 2002, and as of and
for the periods ended March 31, 2005 and 2004, June 30, 2005 and 2004 and
September 30, 2005 and 2004, will be restated and such financial statements
should no longer be relied upon. The Company reached this determination
following discussions with the U.S. Securities and Exchange Commission relating
to the Company's historical accounting policy regarding revenue recognition for
certain custom antibody arrangements.

The restatement will revise the Company's revenue recognition policy for custom
antibody projects to utilize a methodology based on when a project's
specifications have been met and the related antibodies have been shipped,
rather than the percentage-of-completion methodology the Company has used since
1996. The restatement will primarily result in changes to the revenues and
operating expenses line items as reported in the Consolidated Statement of
Operations.

The Audit Committee has discussed the matters noted above with the Company's
independent accountants, KPMG LLP.

A copy of the press release issued by the Company on December 21, 2005 regarding
these matters is attached to this Form 8-K as Exhibit 99.
