Item 5. Other Events.

     On March 7, 2003,  we filed our  Annual  Report on Form 10-K for our fiscal
year ended January 3, 2003 (the "10-K"). Under Item 6, "Selected Financial Data,
we presented a table entitled "Other Operating Data". In this table, we included
a financial  measure,  "EBITDA,"  which we defined as earnings  from  continuing
operations before interest income, interest expense, income taxes,  depreciation
and amortization. "EBITDA" was stated as $46,025,000,  $41,038,000, $49,196,000,
$29,345,000  and  $(13,637,000)  for our  fiscal  years  ended  January 3, 2003,
December  28, 2001,  December  29, 2000,  December 31, 1999 and January 1, 1999,
respectively.  "EBITDA"  is a  financial  measure  that  is  not  calculated  or
presented in accordance with generally accepted accounting principles ("GAAP").

     Regulation G, promulgated  pursuant to Section 401(b) of the Sarbanes-Oxley
Act of 2002  ("Regulation  G"), is effective as of March 28, 2003.  Regulation G
requires a registrant  that  publicly  discloses any material  information  that
includes a "non-GAAP financial measure",  as defined in Regulation G, to provide
the following  information as part of the  disclosure of the non-GAAP  financial
measure:  (a) a presentation of the most directly  comparable  financial measure
calculated and presented in accordance with GAAP; and (b) a  reconciliation  (by
schedule or other clearly  understandable  method),  which shall be quantitative
for  historic  measures  and  quantitative,  to  the  extent  available  without
unreasonable  efforts, for prospective  measures, of the differences between the
non-GAAP financial measure presented and the most directly comparable  financial
measure or measures calculated and presented in accordance with GAAP.

     Accordingly,  pursuant to  Regulation  G, we hereby  provide the  following
presentation and  reconciliation  of the "EBITDA"  financial measure included in
the 10-K:
