           1. I have reviewed this annual report on Form 10-K of P-Com, Inc.;

           2. Based on my knowledge, this 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 report;

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

           4. The registrant's other certifying officer 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 report is being prepared;

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

                     c) Disclosed in this report any change in the registrant's
           internal control over financial reporting that occurred during the
           registrant's most recent fiscal quarter (the registrant's fourth
           fiscal quarter in the case of an annual report) 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 officer 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 functions):

                     a) All significant deficiencies and material weaknesses in
           the design or operation of internal controls 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.
