Item 5.  Other Events and Regulation FD Disclosure.

On Monday,  June 28, 2004,  P-Com,  Inc. (the "Company")  issued a press release
announcing the consummation of a special offer to holders of its existing Series
A, B, C-1 and C-2 Warrants (the "Special Warrant Offer"),  resulting in proceeds
to the Company of approximately $2.3 million.

Under the terms of the  Special  Warrant  Offer,  for a period of 15 days ending
June 25, 2004, the Company  temporarily lowered the exercise price of its issued
and  outstanding  Series A, B, and C-2 Warrants to $.05 per share.  The exercise
prices of the Series A, B and C-2 Warrants  prior to the Special  Warrant Offer,
and following its conclusion,  are $0.12,  $0.20,  and $0.18,  respectively.  In
order to exercise the Series C-2 Warrants at the reduced exercise price of $0.05
per share,  the holders of these  warrants  were  required to exercise  the same
number of Series C-1  Warrants  via a cashless  exercise  provision  whereby the
holder received one share of the Company's common stock for every two Series C-1
Warrants  exercised.  The  participating  holders of the Series A and B warrants
were  allowed to  exercise  up to  one-half  of their  warrants  at the  reduced
exercise  price of $0.05 per share if they also  exercised the remaining half of
their warrants via a cashless exercise provision whereby the holder received one
share of the Company's common stock for every two warrants exercised.

At the conclusion of the Special  Warrant  Offer,  Series A Warrants to purchase
approximately  3.7 million shares,  Series B Warrants to purchase  approximately
5.1 million shares,  Series C-1 Warrants to purchase  approximately 42.0 million
shares and Series C-2  Warrants to  purchase  approximately 42.0 million  shares
remained  outstanding.  These  remaining  warrants are currently  exercisable in
accordance with their original terms and conditions.

Due to certain  exercise  limitations  contained in the Series A, B, C-1 and C-2
Warrants,  certain  warrant  holders were unable to  participate  in the Special
Warrant  Offer.  These  holders  have  accepted  promissory  notes issued by the
Company  that will be  cancelled  upon the  receipt of  stockholder  approval to
remove  the  warrant  exercise  limitations.  Upon the  receipt  of  stockholder
approval,  the  warrant  holders to whom the  promissory  notes were issued will
fully  exercise  their  warrants  and pay the  corresponding  exercise  price by
canceling P-Com's  obligations  under the promissory  notes. As a result,  there
will be no remaining Series A or Series B Warrants  outstanding,  and Series C-1
Warrants to purchase  approximately  22.0 million shares and Series C-2 Warrants
to purchase approximately 22.0 million shares will remain outstanding.

The press  release is attached  hereto as Exhibit  99.1 and is  incorporated  by
reference herein in its entirety.

                     P-COM RAISES ADDITIONAL WORKING CAPITAL
                        REAFFIRMS SECOND QUARTER GUIDANCE
     -----------------------------------------------------------------------
CAMPBELL, CA (June 28, 2004) - P-Com, Inc. (OTCBB:PCOM), a worldwide provider of
broadband wireless access products and services to carriers, commercial
enterprises and government agencies, today announced that it has raised
approximately $2.3 million in equity based financing through a special offer
made to existing holders of P-Com common stock purchase warrants. When combined
with cash proceeds received from the restructuring of its Italian operations
announced on June 15, 2004, P-Com has raised approximately $3.0 million in
additional working capital.

"The completion of the offer to holders of its outstanding warrants achieved
several important objectives - enabling P-Com to raise working capital while
decreasing the number of fully-diluted shares outstanding, reducing the number
of outstanding convertible securities, and further streamlining the company's
capital structure," said P-Com General Counsel and Acting CFO Dan Rumsey. "This
transaction also further strengthens our balance sheet and enables P-Com to
fully execute its 2004 operating plan."

Over the past two years, P-Com has executed a comprehensive financial
restructuring that eliminated a substantial portion of its debt, substantially
cut operating expenses and refocused its operations. In April, P-Com reported
its fourth consecutive quarter of increased revenue and anticipates that this
trend will continue for the second quarter ending June 30, 2004.

For specific details related to the special offer to holders of P-Com's
outstanding warrants, please refer to Form 8-K, which will be filed with the
Securities and Exchange Commission.

SAFE HARBOR STATEMENT

Statements in this release that are forward looking involve known and unknown
risks and uncertainties, which may cause P-Com's actual results in future
periods to be materially different from any future performance that may be
suggested in this news release. Such factors may include, but are not limited
to: the ability to achieve positive cash flow given the Company's existing and
anticipated operating and other costs, and current sales trends; the Company's
deteriorating cash position and its need to raise additional capital, and
whether that capital is available on acceptable terms, if at all; the Company's
ability to negotiate repayment terms with many of its creditors, and settle
outstanding litigation; a continued severe worldwide slowdown in the
telecommunications equipment and services sector; fluctuations in customer
demand, pricing and competition; reliance upon subcontractors; the ability of
P-Com's customers to finance their purchases; the timing of new technology and
product introductions; and the risk of early obsolescence. Many of these risks
and uncertainties are beyond P-Com's control. Reference is made to the
discussion of risk factors detailed in P-Com's filings with the Securities and
Exchange Commission, including its reports on Form 10-K and 10-Q.
