                           RECAPITALIZATION AGREEMENT

December 31, 2003

VIA FACSIMILE AND FIRST CLASS MAIL
----------------------------------

To the  holders of Series B  Convertible  Preferred  Stock  listed on Schedule A
attached hereto

         RE:      RECAPITALIZATION AGREEMENT

Ladies and Gentlemen:

Pursuant to our communication dated November 28, 2003 and subsequent discussions
with SPEEDCOM  Wireless  Corporation's  (the "COMPANY" or  "SPEEDCOM")  majority
holders of the Company's  outstanding  demand notes and the  Company's  Series B
Convertible  Preferred  Stock  (the  "SERIES  B  PREFERRED"),   we  propose  the
recapitalization  transaction described herein pursuant to which all outstanding
shares of Series B  Preferred  shall be  exchanged  for shares of the  Company's
common stock.

As you are aware,  the Company does not have the financial  resources  needed to
pay its outstanding  liabilities.  Now that the sale of substantially all of the
operating  assets of the  Company  to P-Com,  Inc.  ("P-COM")  has  closed,  the
Company's assets consist of approximately  $75,000 in cash and 63,500,000 shares
of P-Com common stock (having a value of approximately $9,525,000 as of December
15,  2003)  and,  in  addition  to  liabilities  associated  with  the  Series B
Preferred, the Company has liabilities of approximately $2,100,000. Inclusive in
the Company's  liabilities are accrued financial  advisory and financing fees in
the amount of $300,000,  which is reduced by $35,600 from the total amount owed.
These fees were calculated using the following remuneration guideline formula:

(($12,260,000  (reported gain on sale) X 2%) + ($4,523,000  (financings) X 2%) =
$335,660

SPEEDCOM  plans  to  contact  all of its  creditors  and  offer  to  settle  its
outstanding liabilities by issuing shares of common stock at a value of $.12 per
share in exchange for and in full satisfaction of such liabilities.

The Series B Preferred is senior to the Company's common stock and restricts the
ability  of the  Company  to engage in  certain  transactions  that the  Company
believes to be in its best  interests.  Thus,  in addition  to  eliminating  all
outstanding  debt and trade  liabilities  of the Company,  the Company wishes to
eliminate all  liabilities  and obligations in respect of the Series B Preferred
by exchanging all of the outstanding Series B Preferred for 76,868,961 shares of
the Company's common stock in the aggregate as described below.

Schedule B attached hereto shows the capitalization of the Company assuming that
all of the  foregoing  liabilities  are so exchanged  for the  Company's  common
stock.




Based on the following assumptions we propose to you as follows:

After  conversion of all  outstanding  obligations  into SPEEDCOM  common stock,
SPEEDCOM will have  approximately  116,500,000  common shares  outstanding.  The
Company  plans to  distribute  approximately  62,500,000  common shares of P-Com
(OTCBB:  PCOM),  which equals  approximately  .552 P-Com, Inc. common shares for
each common share of SPEEDCOM (see Schedule C attached).

Management  anticipates that at some point during the First Quarter of 2004, the
Company may enter into an agreement to merge a private company into SPEEDCOM. It
is believed that post closing,  SPEEDCOM shareholders would have an equity stake
in the new company  ranging from 6%-9%.  Thus,  you would  retain your  SPEEDCOM
shares  and  remain a  shareholder  in the new  company  after the  P-Com  share
distribution.

By executing a counterpart of this letter  agreement in the space provided below
you and the Company agree as follows:

1. Each outstanding  share of Series B Preferred held by you is hereby exchanged
for  20.0411625  shares of the Company's  common stock,  and effective as of the
date of your  execution  of this  letter  agreement,  you shall  have no further
rights with respect to the Series B Preferred  other than the right to be issued
such shares of the Company's common stock in accordance  herewith.  You agree to
deliver to the Company each stock certificate representing your shares of Series
B Preferred (or an appropriate  certificate of loss and indemnity, if requested)
promptly for  cancellation.  The Company shall issue to you the shares of common
stock  for  which  your  Series B  Preferred  is  exchanged  hereunder  promptly
following  the  Effective  Date  (defined  below) upon receipt of your  executed
counterpart  of this letter  agreement  and the related stock  certificates  (or
certificate of loss) representing the Series B Preferred you hold.

2. You hereby  represent to the Company that (i) you are an accredited  investor
as defined in Rule 501(a) of  Regulation D  promulgated  by the  Securities  and
Exchange   Commission  under  the  Securities  Act  of  1933,  as  amended  (the
"SECURITIES ACT"), and (ii) by reason of your business and financial experience,
you have such knowledge, sophistication and experience in business and financial
matters as to be capable of  evaluating  the merits and risk of an investment in
the  Company's  common  stock,  and  that  you are  effecting  the  transactions
contemplated  by this letter  agreement for your own account and not with a view
to the  distribution of any common stock received  hereunder or with any present
intention of  distributing or selling any such common stock except in compliance
with the  Securities  Act. You  understand  and agree that the Company's  common
stock issuable to you hereunder has not been registered under the Securities Act
and that  such  common  stock  may be  resold  only if such  sale is  registered
thereunder  or if an exemption  from the  registration  requirements  thereof is
available.








3. The Company hereby  represents to you that the shares of the Company's common
stock  issuable to you  hereunder,  when and as issued  pursuant to the terms of
this letter agreement, shall be duly authorized,  validly issued, fully paid and
non-assessable,  and free and clear of any liens. Except for the representations
made  in  this  Section  3  and  in  Section  4  below,  the  Company  makes  no
representations  or  warranties  to you  with  respect  to  any  of the  matters
described in this letter agreement.

4. The individuals who have executed this letter  agreement on behalf of you and
the  Company,  respectively,  are  fully  authorized  to sign on  behalf  of the
applicable  party for the purpose of duly and legally  binding such party to the
agreements contained herein.

5. You hereby consent to the exchange and issuance of the Company's common stock
for  all of the  outstanding  Series  B  Preferred  and the  other  transactions
described  in this  letter  agreement  for all  purposes  and  waive any and all
covenants  restricting  such  transactions,  including  without  limitation  the
restrictions  contained  in Section  3.1(c) and 3.9 of the Series B  Convertible
Stock Purchase  Agreement  dated as of August 23, 2001 among the Company and the
other signatories thereto.

6. This letter agreement  constitutes the entire agreement and  understanding of
the parties  hereto with respect to the  exchange of the Series B Preferred  and
supersedes all prior agreements and  understandings,  written or oral, among the
parties with respect thereto.

NOTWITHSTANDING  ANYTHING TO CONTRARY  CONTAINED  HEREIN,  THIS LETTER AGREEMENT
SHALL BE NULL AND VOID AND OF NO FORCE OR EFFECT IF ANY  HOLDER OF THE  SERIES B
PREFERRED FAILS TO ENTER INTO A  RECAPITALIZATION  AGREEMENT WITH THE COMPANY ON

HOLDERS OF SERIES B PREFERRED  HAVE ENTERED INTO SUCH  AGREEMENTS IS REFERRED TO
HEREIN AS THE  "EFFECTIVE  DATE").  THE COMPANY SHALL NOTIFY YOU PROMPTLY OF THE
OCCURRENCE OF THE EFFECTIVE DATE.
