I, Philippe Lemaitre,
certify that:

|1. |  | I
have reviewed this quarterly report on Form 10-Q for the period ending July 2,
          2005;
|-- |  | ------------------------------------------------------------------------------------------------

|2. |  | Based
on my knowledge, this quarterly report does not contain any untrue           statement of
a material fact or omit to state a material fact necessary to make           the
statements made, in light of the circumstances under which such statements           were
made, not misleading with respect to the period covered by this quarterly
          report;
|-- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|3. |  | Based
on my knowledge, the financial statements, and other financial information
          included in this quarterly report, fairly present in all material respects the
          financial condition, results of operations and cash flows of the registrant as
          of, and for, the periods presented in this quarterly report;
|-- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. |  | The
registrants other certifying officers and I are responsible for
          establishing and maintaining disclosure controls and procedures (as defined in
          Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:
|-- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) |  | Designed
such disclosure controls and procedures, or caused such disclosure           controls and
procedures to be designed under our supervision, to ensure that           material
information relating to the registrant, including its consolidated
          subsidiaries, is made known to us by others within those entities, particularly
          during the period in which this quarterly report is being prepared;
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) |  | Designed
such internal control over financial reporting,  or caused such internal control
over  financial  reporting  to be  designed  under our  supervision,  to provide
reasonable  assurance  regarding the reliability of financial  reporting and the
preparation  of financial  statements for external  purposes in accordance  with
generally accepted accounting principles;
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | c) |  | Evaluated
the effectiveness of the registrants disclosure controls and           procedures
and presented in this quarterly report our conclusions about the           effectiveness
of the disclosure controls and procedures, as of the end of the           period covered
by this quarterly report based on such evaluation; and
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | d) |  | Disclosed
in this quarterly report any change in the registrants internal           control
over financial reporting that occurred during the registrants           third
fiscal quarter that has materially affected, or is reasonably likely to
          materially affect, the registrants internal control over financial
          reporting; and
| | -- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|5. |  | The
registrants other certifying officers and I have disclosed, based on           our
most recent evaluation of internal control over financial reporting, to the
          registrants auditors and the audit committee of the registrants
          board of directors (or persons performing the equivalent function):
|-- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | a) |  | All
significant deficiencies and material weaknesses in the design or operation           of
internal control over financial reporting which are reasonably likely to
          adversely affect the registrants ability to record, process, summarize
and           report financial information; and
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) |  | Any
fraud, whether or not material, that involves management or other employees           who
have a significant role in the registrants internal control over
          financial reporting.
