          1.3  Formula Price. The "Formula Price" means the product, rounded to
               -------------
the nearest whole cent, of 85% times the mean average of the 60 closing sale
prices of the Common Stock, as reported by the Nasdaq National Market, for the
60 consecutive trading days ending on and including January 5, 2000, i.e., the
Formula Price is $5.71.

          1.4  Restrictions on Future Sales. Until such time as the Shares are
               ----------------------------
registered for resale as required pursuant to Section 4 hereof or may otherwise
be sold in a single transaction pursuant to Rule 144, the Company shall not
issue, offer or sell any Common Stock (or any security convertible or
exchangeable into Common Stock) on terms more favorable than

                                       2
<PAGE>

the terms that the Shares and the Warrants (as defined below) are being sold to
the Investors pursuant to this Agreement. For this purpose, the price will not
be deemed "more favorable" if it is equal to or more than the product, rounded

Stock) at an absolute price lower than this Agreement's Formula Price (even if
such transaction is otherwise in compliance with this Section 1.4) unless the
Company has first given each Investor written notice of intent to offer an
amount specified in the notice of such securities at a price and on terms
specified in the notice; each Investor then shall have (pro rata) a right of
first offer to purchase some or all of the offered securities at the stated
price and terms. Each Investor shall have 20 days after receipt of the written
notice to accept such right of first offer in whole or in part, and at the end
of such 20 days the right shall expire with respect to such notice to the extent
it has not been exercised. The Company shall then have the right, without
passing again through the right of first offer process, to sell up to all of the
untaken securities at the notice price and terms (or other price and terms more
favorable to the Company) within 60 days after the expiration of the right with
respect to such notice.

debtors and rules of law governing specific performance, injunctive relief or

the Securities Act and applicable state securities Laws, and neither the Company
nor any authorized agent acting on its behalf has taken or will take any action
hereafter that would cause the loss of such exemption.

          2.14 Year 2000. To the Company's knowledge, except for matters which
               ---------
would not in the aggregate result in a material adverse effect on the Company,
each hardware and software product and other computer and information technology
used by the Company in its business (collectively, the "Software") will
accurately receive, provide and process date and time data (including, but not
limited to, calculating, comparing and sequencing) from, into and between the
twentieth and twenty-first centuries, including, without limitation, leap year
calculations, without a decrease in the functionality of the Software so that
the Software will not malfunction, cease to function or provide invalid or
incorrect results as a result of date or time data, to the extent that other
information technology, used in combination with the Software, properly
exchanges date and/or time data with it. To the Company's knowledge, except for
matters which would not in the aggregate result in a material adverse effect on
the Company, the Software is designed to be used prior to, during and after the

will not abnormally end or provide invalid or incorrect results as a result of
date or time data, specifically including date data that represents or
references different centuries or more than one century, (b) has been designed
to ensure year 2000 compatibility, including, but not limited to, date data
century recognition, calculations which accommodate same century and multi-
century formulas and date values, and

                                       10
<PAGE>

date data interface values that reflect the century, and (c) includes "Year 2000
Capabilities," meaning that the Software (i) will manage and manipulate data
involving dates or time, including single century formulas and multi-century
formulas, and will not cause an abnormally ending scenario within the
application or generate incorrect values or invalid results involving such
dates, (ii) provides that all date-related user interface functionalities and
data fields include the indication of century, and (iii) provides that all date-
related data interface functionalities include the indication of century.

          2.15 Investment Company. The Company represents and warrants that it
               ------------------
is not an "investment company" or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended
(the "1940 Act"). In addition, the Company agrees that it shall not become an
"investment company" or a company "controlled" by an "investment company",
within the meaning of the 1940 Act. In the event that the Company breaches the
foregoing, the Company shall forthwith notify the Investors and shall take
immediate corrective action to remedy such breach.

Investor. This Agreement has been duly executed and delivered by and constitutes
a legal, valid and binding obligation of the Investor, enforceable in accordance

     4.   Covenants.
          ---------

          4.1  Registration of Shares.
               ----------------------

               (a)  The Company shall, before the later of (i) 20 days after the
SEC declares effective the Company's Form S-3 registration statement for the
resale of the Common Stock issued by the Company in exchange for its Series B
Convertible Participating Preferred Stock, and (ii) 45 days following the
Closing, prepare and file with the SEC a registration statement on Form S-1
under the Securities Act covering the resale of the Shares by any Investor
(subject to Section 4.1(g), the "Registration Statement"), and corresponding
applications for registration under the blue sky laws of any states for which
any Investor reasonably requests in writing to the Company that the Company
obtain such blue-sky registration (it being understood that in the vast majority
of states no such registration is legally required, due to the Company's Nasdaq
National Market listing or other reasons). The Company shall use its best
efforts to obtain effectiveness of the Registration Statement and such blue sky
registrations as soon thereafter as practicable, and in any event within 90 days
after the Closing. If the Registration Statement has not been declared effective
within 90 days after the Closing or at any such time as a Warrant (as defined in
Section 4.1(h) below) is issued to an Investor, the Company shall also be
required to register for resale any and all Warrant Shares (as defined in
Section 4.1(h) below) to the same extent they were Shares. The Company shall use
its best efforts to keep the Registration Statement and such blue sky
registrations effective after that. Notwithstanding the foregoing, the Company
will only be required to maintain the effectiveness of the Registration
Statement and such blue sky registrations until the earlier of (i) such time as
all of the Shares have been disposed of by the Investors, or (ii) such date on
which the Investors may legally

                                       13
<PAGE>

dispose of all of the Shares in one transaction in the open market pursuant to
Rule 144(k) under the Securities Act. The Company shall also cause the Shares
and any Warrant Shares to be listed on the Nasdaq National Market and on any
stock exchange on which the Common Stock may from time to time be listed. The
Company shall pay all fees and expenses incurred by the Company in connection
with preparing, filing, prosecuting and updating the Registration Statement,
such blue sky applications and registrations, and such listing, including all
registration and filing fees, listing fees, printing expenses, and fees and
disbursements of the Company's counsel and accountants.

               (b)  Each Investor shall cooperate fully with the Company in the
preparation of such Registration Statement and blue sky applications and shall
provide to the Company all information and materials (including updated
information and materials) regarding itself and its proposed method of
disposition of the Shares and any Warrant Shares and take all actions reasonably
requested by the Company to permit the Company to comply with applicable
requirements of the SEC, to comply with applicable requirements of the relevant
blue sky laws, and to obtain the desired acceleration of the effective date of
such Registration Statement.

               (c)  Subject to Section 4.1(d) hereof, the Company shall promptly
prepare and file with the SEC and any relevant blue sky authorities such
amendments and supplements to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep such Registration Statement
effective and to comply with (and enable the Investors to comply with) the
provisions of the Securities Act and Rule 415 thereunder with respect to the
disposition of all the Shares and any Warrant Shares.

               (d)  During the effectiveness of the Registration Statement, the
Company shall promptly notify the Investors of the happening of any event or
other

                                       14
<PAGE>

circumstance as the result of which, in the Company's judgment, (i) the
prospectus included in the Registration Statement, as then in effect, would
include an untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, or (ii) the offer or
resale of the Shares and any Warrant Shares would otherwise have a material and
adverse effect on any proposed or pending acquisition, merger, business
combination or other material transaction involving the Company; and, upon
receipt of such notice and until the earlier of (i) the date the Company makes
available to the Investors a supplemented or amended prospectus meeting the
requirements of the Securities Act and relevant blue sky laws, or (ii) the date
the Company notifies the Investors that the Investors may resume offers and
sales using the prior prospectus, the Investors shall not offer or sell any
Shares and any Warrant Shares pursuant to the Registration Statement (and shall
return all copies of such prior prospectus to the Company if requested to do so
by it). Notwithstanding Section 4.1(c), the Company may continue such "blackout"
period or periods for such period of time as the Company considers reasonably
necessary and in its best interest due to circumstances then existing, or simply
due to the fact that amendments/supplements of a Registration Statement/
prospectus cannot be prepared instantly; but in no event may the Company impose
                                         ---
"blackouts" on the Investors for any period of ten or more consecutive business
days or totaling more than 20 days in any 12 month period (plus any "Permitted
Blackouts" as defined in the Registration Rights Agreement dated as of December
21, 1998 between the Company, Castle Creek Technology Partners LLC and others).

               (e)  The Company shall not be required to apply for or obtain
blue sky registration in any state if in connection therewith or as a condition
thereto it must (i) qualify to do business in such state where it would not
otherwise be required to qualify, (ii) subject itself to

                                       15
<PAGE>

general taxation in such state, (iii) file a general consent to service of
process in such state, or (iv) make any change in its Certificate of
Incorporation or Bylaws, which the Company's Board of Directors determines to be
contrary to the best interests of the Company and its stockholders.

               (f)  Indemnification.
                    ---------------

                    (i)    The Company will indemnify each Investor, and each of
the officers and directors of, and each person controlling, each Investor,
against all claims, losses, expenses, damages and liabilities (or actions in
respect thereto) arising out of or based on (A) any untrue statements (or
alleged untrue statement) of a material fact contained in any prospectus
contained in any registration statement covering the Shares for resale, or based
on any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or (B) any misrepresentation or breach of any representation or warranty given
or made by the Company in this Agreement, and will reimburse each Investor, each
of its officers and directors and each person controlling each Investor, for any
reasonable legal and any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action, provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage or liability is caused by any untrue
statement or omission based upon written information furnished to the Company by
such Investor specifically for use therein.

                    (ii)   Each Investor will indemnify the Company, each of its
directors and officers, and each person who controls the Company within the
meaning of the Securities Act, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on (A) any
untrue statement (or alleged untrue statement) of a material fact contained in
any such prospectus, or any omission (or alleged omission) to state

                                       16
<PAGE>

therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (B) any sale of Shares which violates (or
allegedly violates) the Securities Act because of violation of the prospectus
delivery requirement or because more or less than the information in such
prospectus is given (or alleged to be given) in connection with the sale, or (C)
any misrepresentation or breach of any representation or warranty given or made
by such Investor in this Agreement, and will reimburse the Company, and such
directors, officers, or controlling persons, for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, but in the case of subsection
(f)(ii)(A) to the extent, and only to the extent, that such untrue statement (or
alleged untrue statement) or omission (or alleged omission) is made in such
prospectus in reliance upon and in conformity with written information furnished
to the Company by such Investor specifically for use therein provided, however,
that the indemnity agreement contained in this section 4.1(f)(ii) shall not
apply to amounts paid in settlement of any such claims, losses, expenses,
damages and liabilities if such settlement is effected without the consent of
the Investor, which consent shall not be unreasonably withheld; provided,
further, that in no event shall any indemnity under this section 4.1(f)(ii)
exceed the net proceeds from the offering received by such Investor.

                    (iii)  Each party entitled to indemnification under this
Section 4.1(f) (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
indemnified party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,

                                       17
<PAGE>

shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at the Indemnified Party's expense, and provided further that the
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations hereunder, unless such failure
resulted in actual detriment to the Indemnifying Party. The Indemnified Party
shall provide all cooperation reasonably requested for the defense of the claim
or litigation. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. An Indemnified Party shall not decline any settlement complying with
the foregoing if it requires nothing of the Indemnified Party other than the
payment of money (which is in fact paid by the Indemnifying Party) and does not
include an admission of liability.

                    (iv)   In order to provide for just and equitable
contribution to joint liability under the Securities Act in any case in which
any person or entity entitled to indemnification under Section 4.1(f) makes a
claim for indemnification pursuant to this Section 4.1(f) but it is judicially
determined (by entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 4.1(f) provides for indemnification
in such case; then, and in such case, the party that would otherwise be required
to indemnify under Section 4.1(f) will contribute to the aggregate losses,
claims, damages or liabilities to which the other parties may be subject (after
contribution from others) in such proportion as is appropriate to reflect the
relative fault of the

                                       18
<PAGE>

parties in connection with the losses suffered, as well as any other relevant
equitable considerations.

               (g)    The parties agree that if the Company becomes eligible to
register securities for resale on Form S-3 it may choose to register the Shares
for resale on Form S-3 and, after the SEC declares such Form S-3 registration
statement effective, so notify the Investors, provide all relevant deliverables
(such as a supply of new prospectuses), and then (if the original Form S-1
Registration Statement had already been declared effective) deregister the
Shares from the original Form S-1 Registration Statement. Thereafter such Form
S-3 Registration Statement shall, for all purposes of this Agreement, be deemed
to be the "Registration Statement."

               (h)    If the Shares have not been registered for resale by
date that is three months following the Closing (the "Penalty Date"), the
Company shall be obligated to issue each Investor a warrant (each a "Warrant"
and collectively the "Warrants") on substantially the form attached hereto as
Exhibit C. The number of shares for which each Warrant is exercisable for is to
be determined as follows: for each month (pro rata for partial months) following
the Penalty Date that the Shares have not been registered for resale the Warrant
shall be issued for 3% of the number of Shares such Investor has purchased
pursuant to Section 1.1 hereof. No Warrants shall be issuable if the
Registration Statement is declared effective within the first three months after
the date of Closing. For the purposes of this subsection (h) a "month" shall be
deemed to begin on the same numbered day in each calendar month as the numbered
day of the month on which the Closing occurs. As the obligation to issue the
Warrants accrues, the Company shall reserve for issuance the corresponding
number of Warrant Shares. In no event shall Warrant Shares accrue to an Investor
to the extent that delay was caused by such Investor's violation of Section
4.1(b).

                                       19
<PAGE>

     Although the obligation to issue Warrants will begin 3 months after the
Penalty Date, the Company shall not actually issue such Warrants until the
earlier of (i) the day after the Company first registers the Shares for resale
or (ii) one year and one day after the Penalty Date (the "Warrant Issuance
Date"). In the event clause (ii) in the preceding sentence applies then
additional Warrants shall be issued, pursuant to this subsection, every three
months after the first Warrant Issuance Date, as appropriate (each a "Warrant
Issuance Date" and collectively the "Warrant Issuance Dates"). The maximum
duration of the period of exerciseability for the Warrant shall be until the
third anniversary of the respective Warrant Issuance Date. The initial Exercise
Price per share of the Warrant shall be 80% of the price which was the lowest
closing sale price of the Common Stock, as reported by the Nasdaq National
Market, during the period between the Closing and the respective Warrant
Issuance Date.

               (i)  From the date hereof through a period of 20 days following
the date that the Registration Statement is first declared effective, the
Company shall not register any securities other than securities issued in
connection with (1) any stock option plan, stock purchase plan, stock bonus plan
or other plan for the benefit of employees, officers or directors of the Company
or (2) the exercise of any rights, warrants or options heretofore granted or
issued by the Company for the acquisition of any securities, provided however
the Company may register securities (other than for resale) provided that the
Company includes in such registration statement the registration for resale of
the Shares and any Warrant Shares; provided further, that the registration
rights granted to Investors pursuant to this Agreement shall be enforceable
against the Company in connection with such registration statement as if it were
a registration

                                       20
<PAGE>

statement filed pursuant to this Agreement. Neither such prohibition nor such
piggyback provision shall apply to the Form S-3 registration statement described
in Section 4.1(a)(i).

               (j)  The Company shall cooperate with the Investors to facilitate
the timely preparation and delivery of certificates representing the Shares and
Warrant Shares to be offered for resale pursuant to the Registration Statement
and enable such certificates to be in such denomination or amounts, as the case
may be, as the Investors may reasonably request and registered in such names as
the Investors may request after a Registration Statement which includes the
Shares or Warrant Shares is ordered effective by the SEC, that the Company
deliver, and on such request, the Company shall cause its legal counsel to
deliver to the transfer agent for the Shares and Warrant Shares an opinion of
such counsel in appropriate form to ensure the transfer of such shares without
legend upon delivery by the Investors to the transfer agent of a certificate
that the resale was made via proper delivery of the Prospectus under the
Registration Statement.

          4.2    Deliverables Upon Effectiveness. When and if the SEC declares
                 -------------------------------
the Registration Statement effective, the Company shall promptly deliver to
each Investor:

                 (a)   A certificate signed by the Chief Executive Officer or
President of the Company that the Registration Statement is effective and, to
his knowledge, no stop order with respect to the Registration Statement has been
issued and no proceedings therefor have been instituted.

                 (b)   A legal opinion of Brobeck, Phleger & Harrison LLP,
counsel to the Company, in substantially the form of Exhibit B.

                 (c)   Such number of copies of the Registration Statement and
(from time to time) of each amendment and supplement thereto, such number of
copies of the

                                       21
<PAGE>

prospectus (including (from time to time) any supplemental or amended
prospectus) included in such Registration Statement, and such other related
documents as the Investors may reasonably request in writing in order to
facilitate the disposition of the Shares by the Investors.

          4.3  Current Public Information. With a view to making available to
               --------------------------
Investors the benefits of Rule 144 promulgated under the Securities Act and any
other rule or regulation of the SEC that may at any time permit Investors to
sell securities of the Company to the public without registration or pursuant to
a registration on Form S-3, the Company agrees to:

               (a) make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times from and after the date
of this Agreement so long as the Company remains subject to the periodic
reporting requirements under Sections 13 or 15(d) of the Exchange Act;

               (b)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

               (c)  furnish to each Investor, so long as such Investor owns any
Shares, Warrants or Warrant Shares, forthwith upon request (i) a written
statement by the Company that it has complied with the reporting requirements of
SEC Rule 144, the Securities Act and the Exchange Act, or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company and (iii) such other information as may be reasonably requested in
availing such Investor of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

          4.4  Obligations of the Company. In connection with the registration
               --------------------------
obligations of the Company pursuant to this Agreement, the Company shall, as
expeditiously as reasonably possible:

               (a)  Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Common Stock and
Warrant Shares owned by them.

               (b)  Provide a transfer agent and registrar for all Common Stock
and Warrant Shares registered pursuant hereunder and a CUSIP number for all such
Common Stock and Warrant Shares, in each case not later than the effective date
of such registration.

          4.5  Sales By Investors. Until the Shares are registered for resale
               ------------------
pursuant to Section 4 hereof or otherwise may be sold in a single transaction
pursuant to Rule 144, each Investor shall not, directly or indirectly, (i)
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant for
the sale of, or otherwise dispose of or transfer any shares of the Company's
Common Stock that such Investor owns immediately prior to the Closing or any
securities convertible into or exchangeable for Common Stock that such Investor
owns immediately prior to the Closing, or (ii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of such Common Stock, whether
any such swap or transaction is to be settled by delivery of Common Stock or
other securities, in cash or otherwise.

<PAGE>

          7.6  Survival of Warranties. The representations and warranties of the
               ----------------------
parties contained in or made pursuant to this Agreement shall survive the

To the Investors listed on
Schedule A to the Common
Stock PIPES Purchase Agreement dated January 6, 2000

Ladies and Gentlemen:

     We have acted as counsel for P-Com, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale to you of 7,530,642 shares
of its common stock, par value $.0001 per share, pursuant to the Common Stock
PIPES Purchase Agreement dated January 6, 2000 (the "Stock Purchase Agreement")
among the Company and you.  This opinion letter is being rendered to you
pursuant to Section 5.4 of the Stock Purchase Agreement in connection with the
Closing of the sale of the Shares.  Capitalized terms not otherwise defined in
this opinion letter have the meanings given them in the Stock Purchase
Agreement.

     In connection with the opinions expressed herein, we have made such
examination of matters of law and of fact as we considered appropriate or
advisable for purposes hereof.  As to matters of fact material to the opinions
expressed herein, we have relied upon the representations and warranties as to
factual matters contained in and made by the Company pursuant to the Stock
Purchase Agreement and upon certificates and statements of government officials
and of officers of the Company.  We have also examined originals or copies of
such corporate documents or records of the Company as we have considered
appropriate for the opinions expressed herein.  We have assumed for the purposes
of this opinion letter the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of the documents submitted to us as originals,
the conformity to the original documents of all documents submitted to us as
certified, facsimile or photostatic copies, and the authenticity of the
originals of such copies.

     In rendering this opinion letter we have also assumed: (A) that the Stock
Purchase Agreement has been duly and validly executed and delivered by you or on
your behalf, that you have the power to enter into and perform all your
obligations thereunder, and that the Stock Purchase Agreement constitutes a
valid, legal, binding and enforceable obligation upon you; (B) that the
representations and warranties made in the Stock Purchase Agreement by you are
true and correct; (C) that any wire transfers, drafts or checks tendered by you
will be honored; (D) that you have filed any required State Franchise income or
similar tax returns and have paid any required State Franchise, income or
similar taxes; and (E) that neither Whitman Partners, L.P. nor Seligman
Communications and Information Fund, Inc., nor any person who "controls" either
of them within the meaning of the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, holds any voting securities of the Company as of immediately before the
Closing.

     As used in this opinion letter, the expression "we are not aware" or the
phrase "to our knowledge", or any similar expression or phrase with respect to
our knowledge of matters of fact, means as to matters of fact that, based on the
actual knowledge of individual attorneys

                                  Exhibit A-1
<PAGE>

within the firm principally responsible for handling current matters for the
Company (and not including any constructive or imputed notice of any
information), and after an examination of documents referred to herein and after
inquiries of certain officers of the Company, no facts have been disclosed to us
that have caused us to conclude that the opinions expressed are factually
incorrect; but beyond that we have made no factual investigation for the
purposes of rendering this opinion letter. Specifically, but without limitation,
we have not searched the dockets of any courts and we have made no inquiries of
securities holders or employees of the Company, other than such officers.

     This opinion letter relates solely to the laws of the State of California,
the General Corporation Law of the State of Delaware and the federal law of the
United States and we express no opinion with respect to the effect or
application of any other laws.  Special rulings of authorities administering
such laws or opinions of other counsel have not been sought or obtained.

     Based upon our examination of and reliance upon the foregoing and subject
to the limitations, exceptions, qualifications and assumptions set forth below
and except as set forth in the Stock Purchase Agreement or the Disclosure
Schedule thereto, we are of the opinion that as of the date hereof:

     1.   The Company is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware, and the Company has
the requisite corporate power and authority to own its properties and to conduct
its business as, to our knowledge, it is presently conducted.  The Company is
qualified to do business as a foreign corporation in the state of California.

     2.   The Company has the requisite corporate power and authority to
execute, deliver and perform the Stock Purchase Agreement, and to issue the
Shares, the Warrant and the Warrant Shares.  The Stock Purchase Agreement has
been duly and validly authorized by the Company, duly executed and delivered by
an authorized officer of the Company and constitutes a legal, valid and binding
obligation of the Company, enforceable by you against the Company in accordance
with its terms.

     3.   The Shares have been duly authorized and, upon purchase at the Closing
pursuant to the terms of the Stock Purchase Agreement, will be validly issued,
nonassessable and fully paid, and free of any liens created by the Company.  If
and when issued in accordance with the terms of the Stock Purchase Agreement the
Warrants will be, and if and when issued upon exercise of the Warrants pursuant
to the terms of the Warrants the Warrant Shares will be, validly issued,
nonassessable and fully paid, and free of any liens created by the Company.

     4.   The Company's execution and delivery of, and its performance and
compliance as of the date hereof with the terms of, the Stock Purchase Agreement
do not violate any provision of any federal, Delaware corporate or California
law, rule or regulation applicable to the Company or any provision of the
Company's Restated Certificate of Incorporation or Bylaws and do not conflict
with or constitute a default under the provisions of any judgment, writ, decree
or order specifically identified in the SEC Reports or the material provisions
of any of the material agreements specifically identified in the SEC Reports.

                                  Exhibit A-2
<PAGE>

     5.   Other than in connection with any securities laws, all consents,
approvals, permits, orders or authorizations of, and all qualifications by and
registrations with, any federal or Delaware corporate or California state
governmental authority on the part of the Company required in connection with
the execution and delivery of the Stock Purchase Agreement and consummation at
the Closing of the transactions contemplated by the Stock Purchase Agreement
have been obtained, and are effective, and we are not aware of any proceedings,
or written threat of any proceedings, that question the validity thereof.

     6.   Based in part upon the representations of you in the Stock Purchase
Agreement, the offer and sale of the Shares to you pursuant to the terms of the
Stock Purchase Agreement are exempt from the registration requirements of
Section 5 of the Securities Act of 1933, as amended, and from the qualification
requirements of the California Corporate Securities Law of 1968, as amended.

     Our opinions expressed above are specifically subject to the following
limitations, exceptions, qualifications and assumptions:

     (A)  The legality, validity, binding nature and enforceability of the
Company's obligations under the Stock Purchase Agreement may be subject to or
limited by (1) bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent transfer and other similar laws affecting the rights of creditors
generally; (2) general principles of equity (whether relief is sought in a
proceeding at law or in equity), including, without limitation, concepts of
materiality, reasonableness, good faith and fair dealing, and the discretion of
any court of competent jurisdiction in awarding specific performance or
injunctive relief and other equitable remedies; and (3), without limiting the
generality of the foregoing, the effect of California court decisions and
statutes which indicate that provisions of the Stock Purchase Agreement which
permit you to take action or make determinations may be subject to a requirement
that such action be taken or such determinations be made on a reasonable basis
in good faith or that it be shown that such action is reasonably necessary for
your protection.

     (B)  We express no opinion as to the Company's compliance or noncompliance
with applicable federal or state antifraud or antitrust statutes, laws, rules
and regulations.

     (C)  We express no opinion concerning the past, present or future fair
market value of any securities.

     (D)  We express no opinion as to the enforceability under certain
circumstances of any provisions indemnifying a party against, or requiring
contributions toward, that party's liability for its own wrongful or negligent
acts, or where indemnification or contribution is contrary to public policy or
prohibited by law.  In this regard, we advise you that in the opinion of the
Securities and Exchange Commission, indemnification of directors, officers and
controlling persons of an issuer against liabilities arising under the
Securities Act of 1933, as amended, is against public policy and is therefore
unenforceable.

     (E)  We express no opinion as to the enforceability under certain
circumstances of any provisions prohibiting waivers of any terms of the Stock
Purchase Agreement other than in writing, or prohibiting oral modifications
thereof or modification by course of dealing.  In

                                  Exhibit A-3
<PAGE>

addition, our opinions are subject to the effect of judicial decisions which may
permit the introduction of extrinsic evidence to interpret the terms of written
contracts.

     (F)  We express no opinion as to the effect of Section 1670.5 of the
California Civil Code or any other California law, federal law or equitable
principle which provides that a court may refuse to enforce, or may limit the
application of, a contract or any clause thereof which the court finds to have
been unconscionable at the time it was made or contrary to public policy.

     (G)  We express no opinion as to your compliance with any Federal or state
law relating to your legal or regulatory status.

     (H)  We express no opinion as to the compliance of the Company, you or the
sale of the Common Stock to you with the provisions of the Small Business
Investment Act of 1958, as amended, or any of the regulations promulgated
thereunder.

     (I)  We express no opinion as to the effect of subsequent issuances of
securities of the Company, to the extent that further issuances which may be
integrated with the Closing may include purchasers that do not meet the
definition of "accredited investors" under Rule 501 of Regulation D and
equivalent definitions under state securities or "blue sky" laws.

     (J)  We express no opinion as to Section 7.2 of the Stock Purchase
Agreement to the extent that it purports to exclude conflict of law principles
under California law.

     This opinion letter is rendered as of the date first written above solely
for your benefit in connection with the Stock Purchase Agreement and may not be
delivered to, quoted or relied upon by any person other than you, or for any
other purpose, without our prior written consent.  Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company or the
Shares.  We assume no obligation to advise you of facts, circumstances, events
or developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinions expressed herein.

                                   Very truly yours,

                                   EXHIBIT B

                              _____________, 2000

To the Investors listed on
Schedule A to the Common
Stock PIPES Purchase Agreement dated January 6, 2000

Ladies and Gentlemen:

     We have acted as counsel for P-Com, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale to you of certain Shares of
its common stock, par value $.0001 per share,  pursuant to the Common Stock
PIPES Purchase Agreement dated January 6, 2000 (the "Stock Purchase Agreement")
among the Company and you and in connection with the Company's registration with
the SEC of such Shares for resale by you.  This opinion letter is being rendered
to you pursuant to Section 4.2(b) of the Stock Purchase Agreement in connection
with the SEC declaring effective the Registration Statement for your resale of
the Shares.  Capitalized terms not otherwise defined in this opinion letter have
the meanings given them in the Stock Purchase Agreement.

     In our capacity as counsel to the Company, we have examined, among other
things, originals, or copies identified to our satisfaction as being true
copies, of the Registration Statement on Form S-1 (File No. 333-____________)
initially filed by the Company with the SEC on ____________, 2000, for the
purpose of registering the resale of the Shares under the Securities Act;
Amendment No. 1 to such Registration Statement filed with the SEC on
_____________, 2000; Amendment No. 2 to such Registration Statement filed with
the SEC on _____________, 2000; and oral advice on ______________, 2000, from an
SEC staff examiner, that the SEC had declared such Registration Statement, as so
amended, effective as of ______ p.m., Washington, D.C. time, on _____________,
2000.

     As used in this opinion letter, the phrase "to our knowledge" means as to
matters of fact that, based on the actual knowledge of individual attorneys
within the firm principally responsible for handling current matters for the
Company (and not including any constructive or imputed notice of any
information), no facts have been disclosed to us that have caused us to conclude
that the opinions expressed are factually incorrect; but our affirmative factual
investigation for the purpose of rendering this opinion letter has been limited
to obtaining (a) oral advice received on ___________, from an SEC staff
examiner, that the SEC had declared such Registration Statement, as amended,
effective at _____ p.m. Washington, D.C. time, on _________, 2000 and (b) oral
advice received on ___________, 2000 from an SEC staff examiner that there is no
stop order suspending the effectiveness of the Registration Statement.

     Based upon our examination of and reliance upon the foregoing, we are of
the opinion that as of the date hereof:

                                  Exhibit B-1
<PAGE>

     1.   The Registration Statement has become effective under the Securities
Act and, to our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose are
pending before or contemplated by the SEC.

     This opinion letter is rendered as of the date first written above solely
for your benefit in connection with the Stock Purchase Agreement and the
Registration Statement and may not be delivered to, quoted or relied upon by any
person other than you, or for any other purpose, without our prior written
consent.  Our opinion is expressly limited to the matters set forth above and we
render no opinion, whether by implication or otherwise, as to any other matters
relating to the Company, the Stock Purchase Agreement, the Registration
Statement or the Shares.  We assume no obligation to advise you of facts,
circumstances, events or developments which hereafter may be brought to our
attention and which may alter, affect or modify the opinions expressed herein.

                                        Very truly yours,

                                        BROBECK, PHLEGER & HARRISON LLP

<PAGE>

                                   EXHIBIT C

     THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT
     BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY MAY NOT BE SOLD,
     OFFERED FOR SALE, PLEDGED, HYPOTHECATED, OR OTHERWISE TRANSFERRED EXCEPT
     PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF
     1933, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT
     REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR UNLESS SOLD PURSUANT TO RULE
     144 UNDER SUCH ACT.

                       WARRANT TO PURCHASE COMMON STOCK
                                      of
                                  P-COM, INC.

                        Void after ____________, 200__

     This Warrant is issued to __________________, or its registered assigns
("Holder"), by P-Com, Inc., a Delaware corporation (the "Company"), on
___________, 200__ (the "Warrant Issue Date").  This Warrant is issued in
connection with the Company's issuance to the Holder of Common Stock on January
__, 2000, and the Company's failure to timely register such Common Stock for
resale under the Securities Act of 1933.

     1.   Purchase Shares.  Subject to the terms and conditions hereinafter set
          ---------------
forth, the Holder is entitled, upon surrender of this Warrant at the principal
office of the Company (or at such other place as the Company shall notify the
holder hereof in writing), to purchase from the Company _____________ fully paid
and nonassessable shares of Common Stock of the Company, as constituted on the
Warrant Issue Date (the "Common Stock").  The number of shares of Common Stock
issuable pursuant to this Section 1 (the "Shares") shall be subject to
adjustment pursuant to Section 4 hereof.

     2.   Exercise Price.  The purchase price for the Shares shall be $______
          --------------
per share, as adjusted from time to time pursuant to Section 9 hereof (the
"Exercise Price").  It is acknowledged that the Exercise Price is based on
negotiated terms and is not intended to reflect the current fair market value of
the Common Stock.

     3.   Exercise Period.  Subject to Section 4 below, this Warrant shall be
          ---------------
exercisable, in whole or in part, during the term commencing on the Warrant
Issue Date and ending at 5:00 p.m. on the third anniversary of the Warrant
Issuance Date.

                                  Exhibit C-1
<PAGE>

     4.   Early Termination, Antidilution Adjustments and Registration Statement
          ----------------------------------------------------------------------
Adjustments.
-----------

     (a)  In case of any consolidation of the Company with, or merger of the
Company into, any other corporation (other than a consolidation or merger in
which the Company is the continuing corporation and in which no change occurs in
its outstanding Common Stock), or in case of any sale or transfer of all or
substantially all of the assets of the Company, or in the case of any statutory
exchange of securities with another corporation (including any exchange effected
in connection with a merger of a third corporation into the Company, except
where the Company is the surviving entity and no change occurs in its
outstanding Common Stock), the corporation formed by such consolidation or the
corporation resulting from or surviving such merger or the corporation which
shall have acquired such assets or securities of the Company, as the case may
be, shall execute and deliver to the Holder simultaneously therewith a new
Warrant, satisfactory in form and substance to the Holder, together with such
other documents as the Holder may reasonably request, entitling the Holder
thereof to receive upon exercise of such Warrant the kind and amount of shares
of stock and other securities and property receivable upon such consolidation,
merger, sale, transfer, or exchange of securities, or upon the dissolution
following such sale or other transfer, by a holder of the number of shares of
Common Stock purchasable upon exercise of this Warrant immediately prior to such
consolidation, merger, sale, transfer, or exchange. Such new Warrant shall
contain the same basic other terms and conditions as this Warrant and shall
provide for adjustments which, for events subsequent to the effective date of
such written instrument, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Section 4. The above provisions of this
Section 4(a) shall similarly apply to successive consolidations, mergers,
exchanges, sales or other transfers covered hereby. Notwithstanding the
foregoing, in the event the consideration to be paid to holders of Company
capital stock in any transaction of the nature referred to above in this Section
4(a) (a "Transaction") consists of cash or cash equivalents, then, provided that
the Company shall have given the holder hereof the notice required by Section 9,
this Warrant shall, to the extent it has not been exercised by the effective
date of such Transaction, terminate upon the completion of such Transaction.

     (b)  If the Company at any time shall, by subdivision, combination or
reclassification of securities or otherwise, change any of the securities to
which purchase rights under this Warrant exist into the same or a different
number of securities of any class or classes, this Warrant shall thereafter
represent the right to acquire such number and kind of securities as would have
been issuable as the result of such change with respect to the securities which
were subject to the purchase rights under this Warrant immediately prior to such
subdivision, combination, reclassification or other change. If shares of the
Company's Common Stock are subdivided or combined into a greater or smaller
number of shares of Common Stock, the purchase price under this Warrant shall be
proportionately reduced in the case of a subdivision of shares or
proportionately increased in the case of a combination of shares, in both cases
by the ratio which the total number of shares of Common Stock to be outstanding
immediately after such event bears to the total number of shares of Common Stock
outstanding immediately prior to such event.

                                  Exhibit C-2
<PAGE>

     (c)  Except as set forth herein, no adjustment on account of cash dividends
on the Company's Common Stock or other securities purchasable hereunder will be
made to the purchase price under this Warrant.

     (d)  The Company covenants that during the period the Warrant is
outstanding, it will reserve from its authorized and unissued Common Stock a
sufficient number of shares to provide for the issuance of Common Stock upon the
exercise of any purchase rights under this Warrant.  The Company further
covenants that its issuance of this Warrant shall constitute full authority to
its officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for shares of the Company's Common
Stock upon the exercise of the purchase rights under this Warrant.  The Company
further covenants and agrees (i) that it will not, by amendment of its
Certificate of Incorporation or through reorganization, consolidation, merger,
dissolution or sale of assets, or by any other voluntary act, avoid or seek to
avoid the observation or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by the Company, (ii) promptly
to take such action as may be required of the Company to permit the Holder to
exercise this Warrant and the Company duly and effectively to issue shares of
its Common Stock or other securities as provided herein upon the exercise hereof
and (iii) promptly to take all action required or provided herein to protect the
rights of the Holder granted hereunder against dilution.

     (e)  If the Company declares a dividend on Common Stock, or makes a
distribution to holders of Common Stock, and such dividend or distribution is
payable or made in Common Stock or securities convertible into or exchangeable
for Common Stock, or rights to purchase Common Stock or securities convertible
into or exchangeable for Common Stock, the number of shares of Common Stock for
which this Warrant may be exercised shall be increased, as of the record date
for determining which holders of Common Stock shall be entitled to receive such
dividend or distribution, in proportion to the increase in the number of
outstanding shares (and shares of Common Stock issuable upon conversion of all
such securities convertible into Common Stock) of Common Stock as a result of
such dividend or distribution, and the Exercise Price shall be adjusted so that
the aggregate amount payable for the purchase of all the Warrant Shares issuable
hereunder immediately after the record date for such dividend or distribution
shall equal the aggregate amount so payable immediately before such record date.

     (f)  If the Company declares a dividend on Common Stock (other than a
dividend covered by subsection (e) above) or distributes to holders of its
Common Stock, other than as part of its dissolution or liquidation or the
winding up of its affairs, any shares of its capital stock, any evidence of
indebtedness or any cash or other of its assets (other than Common Stock or
securities convertible into or exchangeable for Common Stock), the Holder shall
receive notice of such event as set forth in Section 9 below.

     (g)  If the Company shall, at any time before the expiration of this
Warrant, sell all or substantially all of its assets and distribute the proceeds
thereof to the Company's stockholders, the Holder shall, upon exercise of this
Warrant have the right to receive, in lieu of the shares of Common Stock of the
Company that the Holder otherwise would have been entitled to receive, the same
kind and amount of assets as would have been issued, distributed or paid to the
Holder upon any such distribution with respect to such shares of Common Stock of
the Company had

                                  Exhibit C-3
<PAGE>

the Holder been the holder of record of such shares of Common Stock receivable
upon exercise of this Warrant on the date for determining those entitled to
receive any such distribution. If any such distribution results in any cash
distribution in excess of the Exercise Price provided by this Warrant for the
shares of Common Stock receivable upon exercise of this Warrant, the Holder may,
at the Holder's option, exercise this Warrant without making payment of the
Exercise Price and, in such case, the Company shall, upon distribution to the
Holder, consider the Exercise Price to have been paid in full and, in making
settlement to the Holder, shall obtain receipt of the Exercise Price by
deducting an amount equal to the Exercise Price for the shares of Common Stock
receivable upon exercise of this Warrant from the amount payable to the Holder.
Notwithstanding the foregoing, in the event the consideration to be paid to
holders of Company capital stock in any transaction of the nature referred to
above in this Section 4(g) (an "Asset Sale Transaction") consists of cash or
cash equivalents and the consideration payable per share of Common Stock of the
Company is less than the Exercise Price hereunder, then, provided that the
Company shall have given the holder hereof the notice required by Section 9,
this Warrant shall, to the extent it has not been exercised by the effective
date of such Transaction, terminate upon the completion of such Transaction.

     (h)  The term "Common Stock" shall mean the Common Stock of the Company as
the same exists at January 6, 2000 or as such stock may be constituted from time
to time, except that for the purpose of this Section 4, the term "Common Stock"
shall include any stock of any class of the Company which has no preference in
respect of dividends or of amounts payable in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Company and which is
not subject to redemption by the Company.

     (i)  Whenever the number of Warrant Shares or the Exercise Price shall be
adjusted as required by the provisions of this Section 4, the Company forthwith
shall file in the custody of its secretary or an assistant secretary, at its
principal office, and furnish to each Holder hereof, a certificate prepared by
its Chief Financial Officer, showing the adjusted number of Warrant Shares and
the adjusted Exercise Price and setting forth in reasonable detail the
circumstances requiring the adjustments.

     (j)  No adjustment in the Exercise Price in accordance with the provisions
of this Section 4 need be made if such adjustment would amount to a change in
such Exercise Price of less than $.01; provided however, that the amount by
which any adjustment is not made by reason of the provisions of this Section
4(j) shall be carried forward and taken into account at the time of any
subsequent adjustment in the Exercise Price.

     (k)  If an adjustment is made under this Section 4 and the event to which
the adjustment relates does not occur, then any adjustments in accordance with
this Section 4 shall be readjusted to the Exercise Price and the number of
Warrant Shares which would be in effect had the earlier adjustment not been
made.

     5.   Method of Exercise.  While this Warrant remains outstanding and
          ------------------
exercisable in accordance with Section 3 above, the Holder may exercise, in
whole or in part, the purchase rights evidenced hereby.  Such exercise shall be
effected by:

                                  Exhibit C-4
<PAGE>

          (a)  the surrender of the Warrant, together with a duly executed copy
of the form of Notice of Exercise attached hereto, to the Secretary of the
Company at its principal offices; and

          (b)  the payment to the Company of cash equal to the aggregate
Exercise Price for the number of Shares being purchased.

     6.   Net Exercise.  In lieu of exercising this Warrant pursuant to Section
          ------------
5, the Holder may elect to receive, without the payment by the Holder of any
additional consideration, shares of Common Stock equal to the value of the
"spread" on the Shares (or the portion thereof being canceled) by surrender of
this Warrant at the principal office of the Company together with the Notice of
Exercise, in which event the Company shall issue to the holder hereof a number
of shares of Common Stock computed using the following formula:

                      Y (A - B)
                      ---------
               X    =     A

Where:    X =  The number of shares of Common Stock to be issued to the Holder
               pursuant to this net exercise;

          Y =  The number of Shares in respect of which the net issue election
               is made;

          A =  The fair market value of one share of the Common Stock at the
               time the net issue election is made;

          B =  The Exercise Price (as adjusted to the date of the net issuance).

For purposes of this Section 6, the fair market value of one share of Common
Stock as of a particular date shall be determined as follows:  (i) if traded on
a securities exchange or through the Nasdaq National Market, the value shall be
deemed to be the average of the closing prices of the securities on such
exchange over the sixty (60) day period ending three (3) days prior to the net
exercise election; and (ii) if traded over-the-counter but not on the Nasdaq
National Market, the value shall be deemed to be the average of the closing bid
or sale prices (whichever is applicable) over the sixty (60) day period ending
three (3) days prior to the net exercise.

     7.   Certificates for Shares.  Upon the exercise of the purchase rights
          -----------------------
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter (with appropriate
restrictive legends, if applicable).

     8.   Issuance of Shares.  The Company covenants that the Shares, when
          ------------------
issued pursuant to the exercise of this Warrant, will be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens, and charges
with respect to the issuance thereof.

     9.   Notice of Adjustment.    So long as this Warrant shall be outstanding,
          --------------------
(a) if the Company shall propose to pay any dividends or make any distribution
upon the Common Stock, or (b) if the Company shall offer generally to the
holders of Common Stock the right to subscribe to or purchase any shares of any
class of Common Stock or securities convertible into Common Stock or any other
similar rights, or (c) if there shall be any proposed capital reorganization of

                                  Exhibit C-5
<PAGE>

the Company in which the Company is not the surviving entity, recapitalization
of the capital stock of the Company, consolidation or merger of the Company with
or into another corporation, sale, lease or other transfer of all or
substantially all of the property and assets of the Company, or voluntary or
involuntary dissolution, liquidation or winding up of the Company, or (d) if the
Company shall give to its stockholders any notice, report or other communication
respecting any significant or special action or event, then in such event, the
Company shall give to the Holder, at least ten (10) days prior to the relevant
date described below, a notice containing a description of the proposed action
or event and stating the date or expected date on which a record of the
Company's stockholders is to be taken for any of the foregoing purposes, and the
date or expected date on which any such dividend, distribution, subscription,
reclassification, reorganization, consolidation, combination, merger,
conveyance, sale, lease or transfer, dissolution, liquidation or winding up is
to take place and the date or expected date, if any is to be fixed, as of which
the holders of Common Stock of record shall be entitled to exchange their shares
of Common Stock for securities or other property deliverable upon such event.

     10.  No Fractional Shares or Scrip.  No fractional shares or scrip
          -----------------------------
representing fractional shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional shares the Company shall make a cash
payment therefor on the basis of the Exercise Price then in effect.

     11.  No Stockholder Rights.  Prior to exercise of this Warrant, the Holder
          ---------------------
shall not be entitled to any rights of a stockholder with respect to the Shares,
including (without limitation) the right to vote such Shares, receive dividends
or other distributions thereon, exercise preemptive rights or be notified of
stockholder meetings, and such holder shall not be entitled to any notice or
other communication concerning the business or affairs of the Company.  However,
nothing in this Section 11 shall limit the right of the Holder to be provided
the Notices required under this Warrant.

     12.  Transfers of Warrant.  Subject to compliance with applicable federal
          --------------------
and state securities laws, this Warrant and all rights hereunder are
transferable in whole or in part by the Holder to any person or entity upon
written notice to the Company in substantially the form as Exhibit A hereto.
The transfer shall be recorded on the books of the Company upon the surrender of
this Warrant, properly endorsed, to the Company at its principal offices.  In
the event of a partial transfer, the Company shall issue to the holders one or
more appropriate new warrants.

     13.  Successors and Assigns.  The terms and provisions of this Warrant
          ----------------------
shall inure to the benefit of, and be binding upon, the Company and the Holder
and their respective successors and assigns.

     14.  Amendments and Waivers.  Any term of this Warrant may be amended and
          ----------------------
the observance of any term of this Warrant may be waived (either generally or in
a particular instance and either retroactively or prospectively), with the
written consent of the Company and the Holder.

     15.  Notices.  All notices required under this Warrant and shall be deemed
          -------
to have been given or made for all purposes (i) upon personal delivery, (ii)
upon confirmation receipt

                                  Exhibit C-6
<PAGE>

that the communication was successfully sent to the applicable number if sent by
facsimile; (iii) one day after being sent, when sent by professional overnight
courier service, or (iv) five days after posting when sent by registered or
certified mail. Notices to the Company shall be sent to the principal office of
the Company (or at such other place as the Company shall notify the Holder
hereof in writing). Notices to the Holder shall be sent to the address of the
Holder on the books of the Company (or at such other place as the Holder shall
notify the Company hereof in writing).

Borrower: P-Com, Inc.
Address:      3175 S. Winchester Blvd.
              Campbell, California  95008

Date:     January 14, 2000

This Loan and Security Agreement is entered into on the above date between
GREYROCK CAPITAL, a Division of Banc of America Commercial Finance Corporation
(Greyrock), whose address is 10880 Wilshire Blvd.  Suite 1850, Los Angeles, CA
90024 and the borrower named above (Borrower), whose chief executive office is
located at the above address (Borrower's Address).  The Schedule to this
Agreement (the Schedule) being signed concurrently is an integral part of this
Agreement.  (Definitions of certain terms used in this Agreement are set forth
in Section 8 below.)

1.  LOANS.

    1.1  Loans.  Greyrock will make loans to Borrower (the Loans), in amounts
determined by Greyrock in its sole discretion, up to the amounts (the Credit
Limit) shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing.  If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit, Borrower
shall immediately pay the amount of the excess to Greyrock, without notice or
demand.

    1.2  Interest. All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement or in another written agreement signed by
Greyrock and Borrower. Interest shall be payable monthly, on the last day of the
month. Interest may, in Greyrock's discretion, be charged to Borrower's loan
account, and the same shall thereafter bear interest at the same rate as the
other Loans.

    1.3  Fees. Borrower shall pay Greyrock the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Greyrock and are
not refundable.

2.  SECURITY INTEREST.

    2.1  Security Interest.  To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to Greyrock a security interest in
all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located (collectively, the Collateral):  All Receivables,
Inventory, Equipment, Investment Property and General Intangibles, including,
without limitation, all of Borrower's Deposit Accounts, all money, all
collateral in which Greyrock is granted a security interest pursuant to any
other present or future agreement, all property now or at any time in the future
in Greyrock's possession, and all proceeds (including proceeds of any insurance
policies, proceeds of proceeds and claims against third parties), all products
of the foregoing, and all books and records related to any of the foregoing*.

    *provided that the Collateral shall not include any right, title or interest
of Borrower arising under any license or other agreement to the extent that the
grant of a security interest in the same is validly prohibited by such license
or other agreement

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

    In order to induce Greyrock to enter into this Agreement and to make Loans,
Borrower represents and warrants to Greyrock as follows, and Borrower covenants
that the following representations will continue to be true, and that Borrower
will at all times comply with all of the following covenants:

    3.1  Corporate Existence and Authority. Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), (iii) do not violate Borrower's articles or certificate of
incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property*, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

Greyrock Capital                                     Loan and Security Agreement
--------------------------------------------------------------------------------

  *if such violation would have a material adverse effect on Borrower

  3.2  Name; Trade Names and Styles.  The name of Borrower set forth in the
heading to this Agreement is its correct name.  Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Greyrock 30 days' prior written notice before changing its
name or doing business under any other name.  Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

  3.3  Place of Business; Location of Collateral.  The address set forth in the
heading to this Agreement is Borrower's chief executive office.  In addition,
Borrower has places of business and Collateral is located only at the locations
set forth on the Schedule.  Borrower will give Greyrock at least 30 days prior
written notice before opening any additional place of business, changing its
chief executive office, or moving any of the Collateral to a location other than
Borrower's Address or one of the locations set forth on the Schedule.

  3.4  Title to Collateral; Permitted Liens.  Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower*.  The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens.  Greyrock now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Greyrock and the Collateral against all claims
of others.  So long as any Loan is outstanding which is a term loan, none of the
Collateral now is or will be affixed to any real property in such a manner, or
with such intent, as to become a fixture.  Borrower is not and will not become a
lessee under any real property lease pursuant to which the lessor may obtain any
rights in any of the Collateral *** and no such lease now prohibits, restrains,
impairs or will prohibit, restrain or impair Borrower's right to remove any
Collateral from the leased premises.  Whenever any Collateral is located upon
premises in which any third party has an interest (whether as owner, mortgagee,
beneficiary under a deed of trust, lien or otherwise), Borrower shall, whenever
requested by Greyrock, use its best efforts to cause such third party to execute
and deliver to Greyrock, in form acceptable to Greyrock, such waivers and
subordinations as Greyrock shall specify, so as to ensure that Greyrock's rights
in the Collateral are, and will continue to be, superior to the rights of any
such third party.  Borrower will keep in full force and effect, and will comply
with all the terms of, any lease of real property where any of the Collateral
now or in the future may be located**.

  *and interests in Collateral licensed by Borrower in the ordinary course of
business

  **in each case in all material respects

  ***except for Permitted Liens

  3.5  Maintenance of Collateral. Borrower will maintain the * Collateral in
good working condition, ordinary wear and tear excepted, and Borrower will not
use the Collateral for any unlawful purpose. Borrower will immediately advise
Greyrock in writing of any material loss or damage to the Collateral.

  *all material tangible personal property

  3.6  Books and Records. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

  3.7  Financial Condition, Statements and Reports. All financial statements now
or in the future delivered to Greyrock have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and fairly reflect the financial condition of Borrower,
at the times and for the periods therein stated. Between the last date covered
by any such statement provided to Greyrock and the date hereof, there has been
no material adverse change in the financial condition or business of Borrower.
Borrower is now and will continue to be solvent.

  3.8  Tax Returns and Payments; Pension Contributions.  Borrower has timely
filed, and will timely file, all tax returns and reports required by applicable
law, and Borrower has timely paid, and will timely pay, all applicable taxes,
assessments, deposits and contributions now or in the future owed by Borrower.
Borrower may, however, defer payment of any contested taxes, provided that
Borrower (i) in good faith contests Borrower's obligation to pay the taxes by
appropriate proceedings promptly and diligently instituted and conducted, (ii)
notifies Greyrock in writing of the commencement of, and any material
development in, the proceedings, and (iii) posts bonds or takes any other steps
required to keep the contested taxes from becoming a lien upon any of the
Collateral.  Borrower is unaware of any claims or adjustments proposed for any
of Borrower's prior tax years which could result in additional taxes becoming
due and payable by Borrower.  Borrower has paid, and shall continue to pay all
amounts necessary to fund all present and future pension, profit sharing and
deferred compensation plans in accordance with their terms, and Borrower has not
and will not withdraw from participation in, permit partial or complete
termination of, or permit the occurrence of any other event with respect to, any
such plan which could result in any liability of Borrower, including any
liability to the Pension Benefit Guarantee Corporation or any other governmental
agency.  Borrower shall, at all times, maintain a separate payroll account which
shall be used exclusively for payment of payroll and payroll taxes and other
items related directly to payroll.

  3.9  Compliance with Law.  Borrower has complied, and will comply, in all
material respects, with all provisions of all applicable laws and regulations,
including, but not limited to, those relating to Borrower's ownership of real or
personal property, the conduct and licensing of Borrower's business, and all
environmental matters.

  3.10 Litigation. Except as disclosed in the Schedule, there is no claim, suit,
litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened * by or against or affecting Borrower in any court or
before any governmental agency (or any basis therefor known to Borrower) which
may result, either separately or in the aggregate, in any material adverse
change in the

--------------------------------------------------------------------------------

financial condition or business of Borrower, or in any material impairment in
the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Greyrock in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of **
or more, or involving *** or more in the aggregate.

  *in writing

  **$250,000    ***$500,000

  3.11  Use of Proceeds.  All proceeds of all Loans shall be used solely for
lawful business purposes.

  3.12  Year 2000 Compliance.  The Borrower has (i) initiated a review and
assessment of all areas within its and each of its subsidiaries' business and
operations (including those affected by suppliers and vendors) that could be
adversely affected by the "Year 2000 Problem" (that is, the risk that computer
applications used by the Borrower or any of its subsidiaries (or its suppliers
and vendors) may be unable to recognize and perform properly date-sensitive
functions involving certain dates prior to and any date after December 31,
1999), (ii) developed a plan and timeline for addressing the Year 2000 Problem
on a timely basis, and (iii) to date, implemented that plan in accordance with
that timetable.  The Borrower reasonably believes that all computer applications
(including those of its suppliers and vendors) that are material to its or any
of its subsidiaries' business and operations will on a timely basis be able to
perform properly date-sensitive functions for all dates before and after January
1, 2000 (that is, be "Year 2000 compliant"), except to the extent that a failure
to do so could not reasonably be expected to have material adverse effect. The
Borrower will promptly notify Greyrock in the event the Borrower discovers or
determines that any computer application (including those of its suppliers and
vendors) that is material to its or any of its subsidiaries' business and
operations will not be Year 2000 compliant on a timely basis, except to the
extent that such failure could not reasonably be expected to have a material
adverse effect.

4. [OMITTED]

5.  ADDITIONAL DUTIES OF THE BORROWER.

   5.1  Insurance.  Borrower shall, at all times, insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Greyrock, in such form and amounts as Greyrock
may reasonably require, and Borrower shall provide evidence of such insurance to
Greyrock, so that Greyrock is * satisfied that such insurance is, at all times,
in full force and effect.  All such insurance policies shall name Greyrock as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Greyrock. Upon receipt of the proceeds of any such
insurance, Greyrock shall ** Greyrock may require reasonable assurance that the
insurance proceeds so released will be so used. If Borrower fails to provide or
pay for any insurance, Greyrock may, but is not obligated to, obtain the same at
Borrower's expense. Borrower shall promptly deliver to Greyrock copies of all
reports made to insurance companies.

  *reasonably

  **release such proceeds to Borrower which shall be utilized by Borrower for
the replacement of the Collateral with respect to which the insurance proceeds
were paid

  5.2  Reports. Borrower, at its expense, shall provide Greyrock with the
written reports set forth in the Schedule, and such other written reports with
respect to Borrower (including budgets, sales projections, operating plans and
other financial documentation), as Greyrock shall from time to time reasonably
specify .

  5.3  Access to Collateral, Books and Records.  At reasonable times, and on one
business day's notice, Greyrock, or its agents, shall have the right to inspect
the Collateral, and the right to audit and copy Borrower's books and records.
Greyrock shall take reasonable steps to keep confidential all * information
obtained in any such inspection or audit, but Greyrock shall have the right to
disclose any such information to its auditors**, regulatory agencies***, and
attorneys, and pursuant to any subpoena or other legal process.  The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $600 per person per day (or such higher amount as shall represent
Greyrock's then current standard charge for the same), plus reasonable out-of-
pockets expenses.  Borrower shall not be charged more than $3,000 per audit
(plus reasonable out-of-pockets expenses), nor shall audits be done more
frequently than four times per calendar year, provided that the foregoing limits
shall not apply after the occurrence of a Default or Event of Default, nor shall
they restrict Greyrock's right to conduct audits at its own expense (whether or
not a Default or Event of Default has occurred).  Borrower will not enter into
any agreement with any accounting firm, service bureau or third party to store
Borrower's books or records at any location other than Borrower's Address,
without first obtaining Greyrock's written consent, which may be conditioned
upon such accounting firm, service bureau or other third party agreeing to give
Greyrock the same rights with respect to access to books and records and related
rights as Greyrock has under this Agreement.

  *confidential

  **(who have agreed to keep such information confidential)

  ***which require disclosure of such information

Obligations in such order as Greyrock shall determine, except for the proceeds
of the sale of obsolete or unneeded Equipment which is sold by Borrower in the
ordinary course of business and the proceeds of which are utilized to acquire
replacements for

such Equipment*. Except as permitted by the immediately preceding sentence,
Borrower shall not commingle proceeds of Collateral with any of Borrower's other
funds or property, and shall hold such proceeds separate and apart from such
other funds and property and in an express trust for Greyrock. Nothing in this
Section limits the restrictions on disposition of Collateral set forth elsewhere
in this Agreement.

  *; provided that, prior to the effective date of the conversion of the Loans

of the foregoing.

  *, except in the case of (a) loans to employees or consultants of the
Borrower, in an amount in the aggregate not to exceed $250,000 at any time
outstanding, and (b) loans by the Borrower to any of its Subsidiaries; provided
that such loans are in the ordinary course of business

  **other than a subsidiary of Borrower

transactions (provided no Event of Default or event which with notice or lapse
of time would constitute an Event of Default has occurred and is continuing)

  5.6  Litigation Cooperation.  Should any third-party suit or proceeding be
instituted by or against Greyrock with respect to any Collateral or in any
manner relating to Borrower, Borrower shall, without expense to Greyrock, make

to Greyrock all certificated securities included in Investment Property, with
all necessary endorsements, and obtain such account control agreements with

Investment Property, as Greyrock shall * request, in form and substance *
satisfactory to Greyrock. Borrower shall have the right to retain all Investment
Property payments and distributions, unless and until a Default or an Event of
Default has occurred.  If a Default or an Event of Default exists, Borrower
shall hold all payments on, and proceeds of, and distributions with respect to,
Investment Property in trust for Greyrock, and Borrower shall deliver all such
payments, proceeds and distributions to Greyrock, immediately upon receipt, in
their original form, duly endorsed, to be applied to the Obligations in such
order as Greyrock shall determine.  Upon the request of Greyrock, any such
distributions and payments with respect to any Investment Property held in any

of the Collateral.

  *reasonably

  6.3  Payment of Obligations.  On the Maturity Date or on any earlier effective
date of termination, Borrower shall pay and perform in full all Obligations,
whether evidenced by installment notes or otherwise, and whether or not all or
any part of such Obligations are otherwise then due and payable.  Without
limiting the generality of the foregoing, if on the Maturity Date, or on any
earlier effective date of termination, there are any outstanding letters of
credit issued based upon an application, guarantee, indemnity or similar
agreement on the part of Greyrock, then on such date Borrower shall provide to
Greyrock cash collateral in an amount equal to 110% of the face amount of all
such letters of credit plus all interest, fees and costs due or (in Greyrock's
estimation) likely to become due in connection therewith, to secure all of the
Obligations relating to said letters of credit, pursuant to Greyrock's then
standard form cash pledge agreement.  Notwithstanding any termination of this
Agreement, all of Greyrock's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Greyrock, Greyrock may, in its sole discretion, refuse to make any further Loans
after termination.  No termination shall in any way affect or impair any right
or remedy of Greyrock, nor shall any such termination relieve Borrower of any
Obligation to Greyrock, until all of the Obligations have been paid and
performed in full*.  Upon payment and performance in full of all the Obligations
** and termination of this Agreement, Greyrock shall promptly deliver to
Borrower termination statements, requests for reconveyances and such other
documents as may be reasonably required to terminate Greyrock's security
interests.

  *or cash collateral, in the case of letter of credit obligations, is provided
pursuant to the preceding sentence

  **(except for contingent obligations to indemnify Greyrock or pay other
unknown amounts in the future)

  7.2  Remedies.  Upon the occurrence and during the continuance of any Event of
Default, and at any time thereafter, Greyrock, at its option, and without notice
or demand of any kind (all of which are hereby expressly waived by Borrower),
may do any one or more of the following: (a) Cease making Loans or otherwise
extending credit to Borrower under this Agreement or any other document or
agreement; (b) Accelerate and declare all or any part of the Obligations to be
immediately due, payable, and performable, notwithstanding any deferred or
installment payments allowed by any instrument evidencing or relating to any
Obligation; (c) Take possession of any or all of the Collateral wherever it may
be found, and for that purpose Borrower hereby authorizes Greyrock without
judicial process to enter onto any of Borrower's premises without interference
to search for, take possession of, keep, store, or remove any of the Collateral,
and remain on the premises or cause a custodian to remain on the premises in
exclusive control thereof, without charge for so long as Greyrock deems it
reasonably necessary in order to complete the enforcement of its rights under
this Agreement or any other agreement; provided, however, that should Greyrock
seek to take possession of any of the Collateral by Court process, Borrower
hereby irrevocably waives: (i) any bond and any surety or security relating
thereto required by any statute, court rule or otherwise as an incident to such
possession; (ii) any demand for possession prior to the commencement of any suit
or action to recover possession thereof; and (iii) any requirement that Greyrock
retain possession of, and not dispose of, any such Collateral until after trial
or final judgment; (d) Require Borrower to assemble any or all of the Collateral
and make it available to Greyrock at places designated by Greyrock which are
reasonably convenient to Greyrock and Borrower, and to remove the Collateral to
such locations as Greyrock may deem advisable; (e) Complete the processing,
manufacturing or repair of any Collateral prior to a disposition thereof and,
for such purpose and for the purpose of removal, Greyrock shall have the right
to use Borrower's premises, vehicles, hoists, lifts, cranes, equipment and all
other property without charge; (f) Collect, receive, dispose of and realize upon
any Investment Property, including withdrawal of any and all funds from any
securities accounts; (g) Sell, lease or otherwise dispose of any of the
Collateral, in its condition at the time Greyrock obtains possession of it or
after further manufacturing, processing or repair, at one or more public and/or
private sales, in lots or in bulk, for cash, exchange or other property, or on
credit, and to adjourn any such sale from time to time without notice other than
oral announcement at the time scheduled for sale.  Greyrock shall have the right
to conduct such disposition on Borrower's premises without charge, for such time
or times as Greyrock deems reasonable, or on Greyrock's premises, or elsewhere
and the Collateral need not be located at the place of disposition.  Greyrock
may directly or through any affiliated company purchase or lease any Collateral
at any such public disposition, and if permissible under applicable law, at any
private disposition.  Any sale or other disposition of Collateral shall not
relieve Borrower of any liability Borrower may have if any Collateral is
defective as to title or physical condition or otherwise at the time of sale;
(h) Demand payment of, and collect any Receivables and General Intangibles
comprising Collateral and, in connection therewith, Borrower irrevocably
authorizes Greyrock to endorse or sign Borrower's name on all collections,
receipts, instruments and other documents, to take possession of and open mail
addressed to Borrower and remove therefrom payments made with respect to any
item of the Collateral or proceeds thereof, and, in Greyrock's sole discretion,
to grant extensions of time to pay, compromise claims and settle Receivables,
General Intangibles and the like for less than face value; and (i) Demand and
receive possession of any of Borrower's federal and state income tax returns and
the books and records utilized in the preparation thereof or referring thereto.
Borrower recognizes that Greyrock may be unable to make a public sale of any or
all of the Investment Property, by reasons of prohibitions contained in
applicable securities laws or otherwise, and expressly agrees that a private
sale to a restricted group of purchasers for investment and not with a view to
any distribution thereof shall be considered a commercially reasonable sale.
All reasonable attorneys' fees, expenses, costs, liabilities and obligations
incurred by Greyrock with respect to the foregoing shall be added to and become
part of the Obligations, shall be due on demand, and shall bear interest at a
rate equal to the highest interest rate applicable to any of the Obligations.

  7.3  Standards for Determining Commercial Reasonableness. Borrower and
Greyrock agree that a sale or other disposition (collectively, sale) of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general, non-
specific terms; (iii) The sale is conducted at a place designated by Greyrock*,
with or without the Collateral being present; (iv) The sale commences at any
time between 8:00 a.m. and 6:00 p.m; (v) Payment of the purchase price in cash
or by cashier's check or wire transfer is required; (vi) With respect to any
sale of any of the Collateral, Greyrock may (but is not obligated to) direct any
prospective purchaser to ascertain directly from Borrower any and all
information concerning the same. Greyrock shall be free to employ other methods
of noticing and selling the Collateral, in its discretion, if they are
commercially reasonable.

--------------------------------------------------------------------------------

  7.4  Power of Attorney.  Upon the occurrence and during the continuance of any
Event of Default, without limiting Greyrock's other rights and remedies,
Borrower grants to Greyrock an irrevocable power of attorney coupled with an
interest, authorizing and permitting Greyrock (acting through any of its
employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Greyrock
agrees to exercise the following powers in a commercially reasonable manner:
(a) Execute on behalf of Borrower any documents that Greyrock may, in its sole
discretion, deem advisable in order to perfect and maintain Greyrock's security
interest in the Collateral, or in order to exercise a right of Borrower or
Greyrock, or in order to fully consummate all the transactions contemplated
under this Agreement, and all other present and future agreements; (b) Execute
on behalf of Borrower any document exercising, transferring or assigning any
option to purchase, sell or otherwise dispose of or to lease (as lessor or
lessee) any real or personal property which is part of Greyrock's Collateral or
in which Greyrock has an interest; (c) Execute on behalf of Borrower, any
invoices relating to any Receivable, any draft against any Account Debtor and
any notice to any Account Debtor, any proof of claim in bankruptcy, any Notice
of Lien, claim of mechanic's, materialman's or other lien, or assignment or
satisfaction of mechanic's, materialman's or other lien; (d) Take control in any
manner of any cash or non-cash items of payment or proceeds of Collateral;
endorse the name of Borrower upon any instruments, or documents, evidence of
payment or Collateral that may come into Greyrock's possession; (e) Endorse all
checks and other forms of remittances received by Greyrock; (f) Pay, contest or
settle any lien, charge, encumbrance, security interest and adverse claim in or
to any of the Collateral, or any judgment based thereon, or otherwise take any
action to terminate or discharge the same; (g) Grant extensions of time to pay,
compromise claims and settle Receivables and General Intangibles for less than
face value and execute all releases and other documents in connection therewith;
(h) Pay any sums required on account of Borrower's taxes or to secure the
release of any liens therefor, or both; (i) Settle and adjust, and give releases
of, any insurance claim that relates to any of the Collateral and obtain payment
therefor; (j) Instruct any third party having custody or control of any books or
records belonging to, or relating to, Borrower to give Greyrock the same rights
of access and other rights with respect thereto as Greyrock has under this
Agreement; (k) Execute and deliver to any securities intermediary or other
Person any entitlement order, account control agreement or other notice,
document or instrument with respect to any Investment Property, and (l) Take any
action or pay any sum required of Borrower pursuant to this Agreement and any
other present or future agreements.  Any and all reasonable sums paid and any
and all reasonable costs, expenses, liabilities, obligations and reasonable
attorneys' fees incurred by Greyrock with respect to the foregoing shall be
added to and become part of the Obligations, shall be payable on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.  In no event shall Greyrock's rights under the foregoing
power of attorney or any of Greyrock's other rights under this Agreement be
deemed to indicate that Greyrock is in control of the business, management or
properties of Borrower.

  7.5  Application of Proceeds.  All proceeds realized as the result of any sale
or other disposition of the Collateral shall be applied by Greyrock first to the
reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Greyrock in the exercise of its rights under this Agreement, second
to the interest due upon any of the Obligations, and third to the principal of
the Obligations, in such order as Greyrock shall determine in its sole
discretion.  Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Greyrock for any deficiency.
If Greyrock, in its sole discretion, directly or indirectly enters into a
deferred payment or other credit transaction with any purchaser at any sale of
Collateral, Greyrock shall have the option, exercisable at any time, in its sole
discretion, of either reducing the Obligations by the principal amount of
purchase price or deferring the reduction of the Obligations until the actual
receipt by Greyrock of the cash therefor.

  7.6  Remedies Cumulative.  In addition to the rights and remedies set forth in
this Agreement, Greyrock shall have all the other rights and remedies accorded a
secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Greyrock and Borrower, and all of such rights and
remedies are cumulative and none is exclusive.  Exercise or partial exercise by
Greyrock of one or more of its rights or remedies shall not be deemed an
election, nor bar Greyrock from subsequent exercise or partial exercise of any
other rights or remedies.  The failure or delay of Greyrock to exercise any
rights or remedies shall not operate as a waiver thereof, but all rights and
remedies shall continue in full force and effect until all of the Obligations
have been fully paid and performed.

   9.1   Interest Computation.  In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Greyrock
(including proceeds of Receivables and payment of the Obligations in full) shall
be deemed applied by Greyrock on account of the Obligations three Business Days
after receipt by Greyrock of immediately available funds*.  Greyrock shall not,
however, be required to credit Borrower's account for the amount of any item of
payment which is unsatisfactory to Greyrock in its discretion, and Greyrock may
charge Borrower's Loan account for the amount of any item of payment which is
returned to Greyrock unpaid.

   *provided that principal payments on the Term Loan shall be applied thereto
on the date of receipt by Greyrock of immediately available funds, if such funds
are received before 10:00 AM Pacific time, or on the next Business Day, if such
funds are received after 10:00 AM Pacific time

   9.2   Application of Payments. All payments with respect to the Obligations
may be applied, and in Greyrock's sole discretion reversed and re-applied, to
the Obligations, in such order and manner as Greyrock shall determine in its
sole discretion.

   9.3   Charges to Account. Greyrock may, in its discretion, require that
Borrower pay monetary Obligations in cash to Greyrock, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans.

   9.4   Monthly Accountings.  Greyrock shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement.  Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Greyrock), unless Borrower
notifies Greyrock in writing to the contrary within sixty days after each
account is rendered, describing the nature of any alleged errors or admissions.

    9.5  Notices. All notices to be given under this Agreement shall be in
writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, or by fax, addressed to Greyrock or Borrower at the addresses shown
in the heading to this Agreement, or at any other address designated in writing
by one party to the other party. All notices shall be deemed to have been given
upon delivery in the case of notices personally delivered, or at the expiration
of one Business Day following delivery to the private delivery service, or two
business days following the deposit thereof in the United States mail, with
postage prepaid, or on transmission and receipt thereof in the case of notices
given by fax.

   9.6   Severability. Should any provision of this Agreement be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Agreement, which shall continue in full force
and effect.

   9.7   Integration. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and compl ete agreement between Borrower and Greyrock and
supersede all prior and contemporaneous negotiations and oral representations
and agreements, all of which are merged and integrated in this Agreement. There
                                                                          -----
are no oral understandings, representations or agreements between the parties
-----------------------------------------------------------------------------
which are not set forth in this Agreement or in other written agreements signed
-------------------------------------------------------------------------------
by the parties in connection herewith.
-------------------------------------

   9.8   Waivers. The failure of Greyrock at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Greyrock shall not waive
or diminish any right of Greyrock later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Greyrock shall be deemed to have been
waived by any act or knowledge of Greyrock or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Greyrock and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Greyrock on which Borrower is or may in any way be liable, and notice of any
action taken by Greyrock, unless expressly required by this Agreement.

   9.9   Amendment. The terms and provisions of this Agreement may not be waived
or amended, except in a writing executed by Borrower and a duly authorized
officer of Greyrock.

   9.10  Time of Essence. Time is of the essence in the performance by Borrower
of each and every obligation under this Agreement.

   9.11  Attorneys Fees and Costs.  Borrower shall reimburse Greyrock for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Greyrock, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Greyrock incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or

Greyrock or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)
reasonable attorneys' fees and costs incurred in the enforcement of, execution
upon or defense of any order, decree, award or judgment. All attorneys' fees and
costs to which Greyrock may be entitled pursuant to this Paragraph shall
immediately become part of Borrower's Obligations, shall be due on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.

   9.12  Benefit of Agreement. The provisions of this Agreement shall be binding
upon and inure to the benefit of the respective successors, assigns, heirs,
beneficiaries and representatives of Borrower and Greyrock; provided, however,
that Borrower may not assign or transfer any of its rights under this Agreement
without the prior written consent of Greyrock, and any prohibited assignment
shall be void. No consent by Greyrock to any assignment shall release Borrower
from its liability for the Obligations.

   9.13  Joint and Several Liability.  If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

   9.14  Limitation of Actions. Any claim or cause of action by Borrower against
Greyrock, its directors, officers, employees, agents, accountants or attorneys,
based upon, arising from, or relating to this Loan Agreement, or any other
present or future document or agreement, or any other transaction contemplated
hereby or thereby or relating hereto or thereto, or any other matter, cause or
thing whatsoever, occurred, done, omitted or suffered to be done by Greyrock,
its directors, officers, employees, agents, accountants or attorneys*, shall be
barred unless asserted by Borrower by the commencement of an action or
proceeding in a court of competent jurisdiction by the filing of a complaint
within one year after the first act, occurrence or omission upon which such
claim or cause of action, or any part thereof, is based, and the service of a
summons and complaint on an officer of Greyrock, or on any other person
authorized to accept service on behalf of Greyrock, within thirty (30) days
thereafter. Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Greyrock in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

define or interpret any term or provision of this Agreement.  The term

limited to)".  This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Greyrock or Borrower under any
rule of construction or otherwise.

OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE

Date:     January 14, 2000

This Schedule is an integral part of the Loan and Security Agreement between
Greyrock Capital, a Division of Banc of America Commercial Finance Corporation
(Greyrock) and the above-borrower (Borrower) of even date.

================================================================================

1.  CREDIT LIMIT
    (Section 1.1):       An amount not to exceed $12,000,000 at any one time
                         outstanding.

                         The Loans will initially be made as a term loan (the
                         "Term Loan"), in one disbursement. The principal amount
                         of the Term Loan will be payable on termination of this
                         Agreement, except as otherwise provided herein. The
                         Term Loan may be pre-paid, in whole or in part, without
                         premium or penalty; provided that if the Term Loan is
                         pre-paid in whole or in part prior to the exercise of
                         the Greyrock Option provided for in Section 7(c) below,
                         then Greyrock may retain the Warrants, regardless of
                         which Greyrock Option is selected.

                         Amounts of the Term Loan that are prepaid may not be
                         reborrowed.

                         The Term Loan may be converted to a revolving
                         Receivable Facility as provided in Section 7(c) below.

================================================================================
2.  INTEREST.

       Interest Rate (Section 1.2):

                         A rate equal to the "Prime Rate" plus 2% per annum,
                         calculated on the basis of a 360-day year for the
                         actual number of days elapsed, provided that the
                         interest rate in effect in each month shall not be less
                         than 8% per annum, regardless of the amount of the
                         Obligations outstanding. The interest rate applicable
                         to all Loans shall be adjusted monthly as of the first
                         day of each month, and the interest to be charged for
                         each month shall be based on the highest "Prime Rate"
                         in effect during said month. "Prime Rate" means the
                         announced "Prime

                         N.A. (or its successor) whether or not that rate is the
                         lowest interest rate charged by said bank. If the Prime
                         Rate, as defined, is unavailable, "Prime Rate" shall
                         mean the highest of the prime rates published in the
                         Wall Street Journal on the first business day of the
                         month, as the base rate on corporate loans at large

7.  ADDITIONAL PROVISIONS:

     (a)  Conditions. The making of the initial Loan and subsequent Loans
          hereunder is subject to the following additional conditions precedent:

          (1)  Additional Equity Investment Borrower shall have received
               $43,000,000 in cash proceeds from the issuance by Borrower of its
               equity securities, within two Business Days after the date hereof
               and concurrently with or prior to the initial Loan hereunder, and
               Borrower shall provide evidence of the same to Greyrock,
               reasonably satisfactory to Greyrock.

          (2)  Cash Collateral. Borrower shall provide to Greyrock cash
               collateral in the amount of $6,000,000 (the "Cash Collateral")
               which shall constitute "Collateral" for all purposes of this
               Agreement. The Cash Collateral may, in the discretion of
               Greyrock, be provided by Greyrock withholding said sum from the
               proceeds of the Loans made pursuant hereto. The Cash Collateral
               need not be maintained in a separate account. The Cash Collateral
               shall bear interest at a rate equal to the Prime Rate minus 3%
               per annum, computed on the basis of a 360-day year. Provided no
               Event of Default or event which with notice or lapse of time
               would constitute an Event of Default has occurred and is
               continuing, accrued interest on the Cash Collateral shall be paid
               to Borrower monthly, or, in the discretion of Greyrock, applied
               to the outstanding Loans and other Obligations.

     (b)  Warrants. The Borrower shall provide Greyrock with three-year warrants
          to purchase 200,000 shares of common stock of the Borrower, on the
          terms set forth in the Warrant to Purchase Stock and related documents
          being executed concurrently with this Agreement, at $5.71 per share
          (the "Warrants"). The Warrants shall contain such terms and provisions
          as Borrower and Greyrock shall agree, and the Warrant shall be issued
          in the form of two separate Warrants, one issued to Greyrock with
          respect to 120,000 shares, and one issued to Greyrock's participant,
          Silicon Valley Bank ("Silicon"), with respect to the remaining 80,000
          shares.. In addition, concurrently, Borrower and Greyrock and Silicon
          Valley Bank shall enter into an Anti-Dilution Agreement and
          Registration Rights Agreement in such form as Borrower and Greyrock
          shall agree. The Warrants shall be deemed fully earned on the date
          hereof, shall be in addition to all interest and other fees, and shall
          be non-refundable, except as provided in Section 7(c) below, provided
          that, in the event this Agreement is terminated for any reason prior
          to the exercise of the Greyrock Option, Greyrock and Silicon shall
          have the right to retain the Warrants. Greyrock represents that it is
          acquiring the Warrant for its own account and not with a view to the
          distribution thereof. Greyrock further represents that it is an
          accredited investor within the meaning of Rule 501(a) promulgated
          under the Securities Act of 1933 (the "Securities Act"). Greyrock
          understands that the Warrant has not been registered under the
          Securities Act or any state securities laws. Greyrock understands
          further that the Warrant will be acquired for investment and may not
          be sold, pledged or otherwise transferred without an effective
          registration statement thereof under the Securities Act and any
          applicable state securities laws or pursuant to Rule 144 or an opinion
          of counsel reasonably satisfactory to the Company and its counsel that
          such registration is not required.

--------------------------------------------------------------------------------

     (c)  Option to Convert to Receivable Facility.

               (1)  Initial Review. During the 60-day period commencing on the
                    date hereof, Greyrock shall have the right to complete its
                    audits and investigations with respect to the Borrower and
                    its business, in order to enable Greyrock to decide whether
                    to convert the Loan facility to a Receivable Facility as
                    provided below. The Borrower shall cooperate in said audits
                    and investigations and shall provide such information and
                    documentation in connection therewith as Greyrock shall
                    reasonably request.

               (2)  Option to Convert to Receivable Facility. Within 60 days
                    after the date hereof, Greyrock shall have the option (the
                    "Greyrock Option") of doing either of the following: (i)
                    releasing the Cash Collateral to Borrower and converting the
                    Loans to an account receivable loan facility (the
                    "Receivable Facility") as provided below (the "Receivable
                    Facility Option"); or (ii) retaining the Cash Collateral as
                    Collateral and releasing its and Silicon's interest in the
                    Warrants (the "Warrant Release Option"). Greyrock shall
                    exercise said option by giving written notice to the
                    Borrower within said 60-day period as to whether Greyrock
                    elects the Receivable Facility Option or the Warrant Release
                    Option. If Greyrock fails to give such written notice,
                    Greyrock shall be deemed to have exercised the Warrant
                    Release Option. The date on which Greyrock gives written
                    notice to Borrower as to which option it selects is referred
                    to herein as the Option Effective Date.

               (3)  Warrant Release Option. If Greyrock elects the Warrant
                    Release Option, Greyrock shall, upon written request of
                    Borrower, execute and deliver, and cause Silicon to execute
                    and deliver, such documents as Borrower shall reasonably
                    specify in order to release their interest in the Warrants.

               (4)  Receivable Facility Option. If Greyrock elects the
                    Receivable Facility Option, then the following shall occur:

                    (A)  Release of Cash Collateral. Greyrock shall, within said
                         60-day period, release the Cash Collateral by wiring
                         the same to such account as the Borrower shall specify
                         in written instructions to Greyrock.

                    (B)  Credit Limit. Effective on the Option Effective Date,
                         the Credit Limit shall be modified to be the following:
                         The lesser of (i) $12,000,000 or (ii) 85% of the amount
                         of Borrower's Eligible Receivables (as defined in
                         Exhibit A hereto). In the event, on the Option
                         Effective Date, the total Obligations exceed the Credit
                         Limit, Borrower shall pay the excess to Greyrock
                         immediately, without notice or demand, and without
                         limiting the foregoing, Greyrock may, in its discretion
                         apply the Cash Collateral to any such excess and
                         release the remaining Cash Collateral to Borrower as
                         provided in Section 7(c)(4)(A) above.

                    (C)  Receivable Provisions. Effective on the Option
                         Effective Date and thereafter, the provisions of
                         Exhibit A hereto shall be effective.

               (5)  Legal Opinion Post-Closing. Within 20 days after the date
                    hereof, Borrower shall provide to Greyrock an opinion of
                    Borrower's counsel with respect to the due execution and
                    delivery of this Agreement and the

                    reasonably request.

               (6)  Subsidiary Guarantees Post-Closing. Within 60 days after the
                    date hereof (and in any event if Greyrock exercises the
                    Receivable Facility Option, within 10 days after the Option
                    Effective Date), Borrower shall cause each of its U.S.

                    Greyrock a first-priority security interest in all of their
                    assets (subject to "Permitted Liens" defined in the same
                    manner as under this Agreement), on substantially the same
                    terms as the provisions of this Agreement, (iii) all such

                   Exhibit A to Loan and Security Agreement

                        Receivable Facility Provisions

1.  RECEIVABLES.

    1.1  Representations Relating to Receivables. Borrower represents and
warrants to Greyrock as follows: Each Eligible Receivable shall, on the date
each Loan is requested and made, represent an undisputed, bona fide, existing,
unconditional obligation of the Account Debtor on such Receivable created by the
sale, delivery, and acceptance of goods or the rendition of services, in the
ordinary course of Borrower's business.

    1.2  Representations Relating to Documents and Legal Compliance. Borrower
represents and warrants to Greyrock as follows: All statements made and all
unpaid balances appearing in all invoices, instruments and other documents
evidencing the Eligible Receivables are and shall be true and correct and all
such invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract. All sales and
other transactions underlying or giving rise to each Eligible Receivable shall
comply with all applicable laws and governmental rules and regulations in all
material respects. All signatures and indorsements on all documents,
instruments, and agreements relating to all Eligible Receivables are and shall
be genuine, and all such documents, instruments and agreements are and shall be
legally enforceable in accordance with their terms.

    1.3  Schedules and Documents relating to Receivables. Borrower shall deliver
to Greyrock transaction reports and loan requests, schedules and assignments of
all Receivables, and schedules of collections, all on Greyrock's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Greyrock's security interest and other rights in all of
Borrower's Receivables, nor shall Greyrock's failure to advance or lend against
a specific Receivable affect or limit Greyrock's security interest and other
rights therein. Together with each such schedule and assignment, or later if
requested by Greyrock, Borrower shall furnish Greyrock with copies (or, at
Greyrock's request, originals) of all contracts, orders, invoices, and other
similar documents, and all original shipping instructions, delivery receipts,
bills of lading, and other evidence of delivery, for any goods the sale or
disposition of which gave rise to such Receivables, and Borrower warrants the
genuineness of all of the foregoing. Borrower shall also furnish to Greyrock an
aged accounts receivable trial balance in such form and at such intervals as
Greyrock shall reasonably request. In addition, Borrower shall deliver to
Greyrock the originals of all instruments, chattel paper, security agreements,
guarantees and other documents and property evidencing or securing any
Receivables, immediately upon receipt thereof and in the same form as received,
with all necessary indorsements.

    1.4  Collection of Receivables. Borrower shall have the right to collect all
Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Greyrock, and Borrower shall deliver all such payments and proceeds to Greyrock,
within one Business Day after receipt of the same, in their original form, duly
endorsed, to be applied to the Obligations in such order as Greyrock shall
determine.

    1.5  Disputes. Borrower shall notify Greyrock promptly of all disputes or
claims relating to Eligible Receivables on the regular reports to Greyrock.
Borrower shall not forgive, or settle any Receivable for less than payment in
full, or agree to do any of the foregoing, except that Borrower may do so,
provided that: (i) Borrower does so in good faith, in a commercially reasonable
manner, in the ordinary course of business, and in arm's length transactions,
which are reported to Greyrock on the regular reports provided to Greyrock; (ii)
no Default or Event of Default has occurred and is continuing; and (iii) taking
into account all such settlements and forgiveness, the total outstanding Loans
and other Obligations will not exceed the Credit Limit.

    1.6  Verification. Greyrock may, from time to time, at reasonable times and
in a reasonable manner, verify directly with the respective Account Debtors the
validity, amount and other matters relating to the Receivables, by means of
mail, telephone or otherwise, either in the name of Borrower or Greyrock or such
other name as Greyrock may choose, and Greyrock or its designee may, at any
time, notify Account Debtors that it has a security interest in the Receivables.

                               Exhibit A- Page 1

    1.7  No Liability. Greyrock shall not under any circumstances be responsible
or liable for any shortage or discrepancy in, damage to, or loss or destruction
of, any goods, the sale or other disposition of which gives rise to a
Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Greyrock be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable. Nothing herein shall, however, relieve Greyrock from liability for
its own gross negligence or willful misconduct.

    1.8  Definition. As used in this Agreement, "Eligible Receivables" means
unconditional Receivables arising in the ordinary course of Borrower's business
from the completed sale of goods or rendition of services, which Greyrock, in
its good-faith business judgment, shall deem eligible for borrowing, based on
such considerations as Greyrock may from time to time deem appropriate, notice
of which Greyrock shall give to Borrower.

    1.9  Reporting. In addition to the reports provided elsewhere in this
Agreement, Borrower shall provide to Greyrock the following: (i) Monthly
Receivable agings, aged by invoice date, within 10 Business Days after the end
of each month, and (ii) Monthly accounts payable agings, aged by invoice date,
and outstanding or held check registers within 10 Business Days after the end of
each month.
