EXHIBIT B

                          REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION RIGHTS AGREEMENT, dated as of March 29, 2001, between the
investor or investors signatory hereto (each an "Investor" and together the
"Investors"), and World Wide Wireless Communications, Inc., a Nevada corporation
(the "Company").

     WHEREAS, simultaneously with the execution and delivery of this Agreement,
the Investors are purchasing from the Company, pursuant to a Senior Secured
Convertible Debentures and Warrants Purchase Agreement dated the date hereof
(the "Purchase Agreement") (capitalized terms not defined herein shall have the
meanings ascribed to them in the Purchase Agreement), $750,000, in the
aggregate, principal amount of the Company's 8% Convertible Debentures; and

     WHEREAS, the Company desires to grant to the Investors the registration
rights set forth herein with respect to the Conversion Shares of Common Stock
issuable upon conversion of, or as interest upon, the Convertible Debentures,
shares of Common Stock issuable upon exercise of the Warrants purchased pursuant
to the Purchase Agreement and shares issuable in the event of a registration
default pursuant to Section 3(e) (the "Securities").

     NOW, THEREFORE, the parties hereto mutually agree as follows:

     Section 1. Registrable Securities. As used herein the term "Registrable
Security" means 200% of the Securities until (i) the Registration Statement has
been declared effective by the Commission, and all Securities have been disposed
of pursuant to the Registration Statement, (ii) all Securities have been sold
under circumstances under which all of the applicable conditions of Rule 144 (or
any similar provision then in force) under the Securities Act ("Rule 144") are
met, (iii) all Securities have been otherwise transferred to holders who may
trade such Securities without restriction under the Securities Act, and the
Company has delivered a new certificate or other evidence of ownership for such
Securities not bearing a restrictive legend or (iv) such time as, in the opinion
of counsel to the Company, all Securities may be sold without any time, volume
or manner limitations pursuant to Rule 144(k) (or any similar provision then in
effect) under the Securities Act. In the event of any merger, reorganization,
consolidation, recapitalization or other change in corporate structure affecting
the Common Stock, such adjustment shall be deemed to be made in the definition
of "Registrable Security" as is appropriate in order to prevent any dilution or
enlargement of the rights granted pursuant to this Agreement.

     Section 2. Restrictions on Transfer. Each Investor acknowledges and
understands that prior to the registration of the Securities as provided herein,
the Securities are "restricted securities" as defined in Rule 144 promulgated
under the Securities Act. Each Investor understands that no disposition or
transfer of the Securities may be made by Investor in the absence of (i) an
opinion of counsel to the Investor, in form and substance reasonably

<PAGE>

satisfactory to the Company, that such transfer may be made without registration
under the Securities Act or (ii) such registration.

     With a view to making available to the Investors the benefits of Rule 144
under the Securities Act or any other similar rule or regulation of the
Commission that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

          (a) comply with the provisions of paragraph (c)(1) of Rule 144;

          (b) file with the Commission in a timely manner all reports and other
     documents required to be filed with the Commission pursuant to Section 13
     or 15(d) under the Exchange Act by companies subject to either of such
     sections, irrespective of whether the Company is then subject to such
     reporting requirements; and

          (c) Upon request by the Transfer Agent, the Company shall provide the
     Transfer Agent an opinion of counsel, which opinion shall be reasonably
     acceptable to the Transfer Agent, that the Investor has complied with the
     applicable conditions of Rule 144 ( or any similar provision then in force)
     under the Securities Act.

     Section 3. Registration Rights With Respect to the Securities.

          (a) On the earlier to occur of (i) the registration statement filed
     pursuant to the Equity Line is not declared effective within 180 calendar
     days from the Closing Date, (ii) any date the effectiveness of the
     Registration Statement is not maintained during the term of the Equity Line
     Agreement after it is declared effective by the Commission, or (iii) the
     date the Company violates any material provision of the Purchase Agreement
     or any of the exhibits thereto (the "Registration Event"), the Company
     agrees that it will prepare and file with the Commission, within 45
     calendar days from the date of the Registration Event, a registration
     statement (on Form S-1, or other appropriate registration statement form)
     under the Securities Act (the "Registration Statement"), at the sole
     expense of the Company (except as provided in Section 3(c) hereof), in
     respect of the Investors, so as to permit a public offering and resale of
     the Securities under the Act by the Investors as selling stockholders and
     not as underwriters.

          The Company shall cause such Registration Statement to become
     effective within 90 calendar days from the date of the Registration Event,
     or, if earlier, within five (5) days of SEC clearance to request
     acceleration of effectiveness. The number of shares designated in the
     Registration Statement to be registered shall include all the Warrant
     Shares, 100% of the already converted Conversion Shares held by any
     Investor on the filing date and at least 200% of the greater of the number
     of shares which would be issuable upon the conversion of the then
     outstanding principal amount of the Convertible Debentures at the
     Conversion Price in effect (i) on the Closing Date, or (ii) on the date of
     the filing of the Registration Statement, and such number of shares as the
     Company deems prudent for the purpose of issuing shares of Common Stock as
     interest on the

                                       2
<PAGE>

     Convertible Debentures, and shall include appropriate language regarding
     reliance upon Rule 416 to the extent permitted by the Commission. The
     Company will notify the Investors and its transfer agent of the
     effectiveness of the Registration Statement within one (1) Trading Day of
     such event. After the Effective Date, within fifteen (15) days after the
     day on which the number of Securities registered for public offering and
     resale by the Investors is less than 125% of the number of Securities
     (calculated at the Conversion Price on such date) held by the Investors on
     such date (the "Further Registration Date"), the Company shall file a
     further registration statement registering a number of shares of Common
     Stock to the extent that at least 200% of the shares which would be
     required to be issued upon the conversion of the remaining Convertible
     Debentures at the Conversion Price on the date of the filing of such
     further registration statement are registered and shall use diligent best
     efforts to prosecute such additional registration statement to
     effectiveness within sixty (60) calendar days of the date of the Further
     Registration Date. Each Investor shall have the right to convert all or any
     of its Convertible Debenture into up to a number of registered shares of
     Common Stock equal to such Investor's fraction of the aggregate Purchase
     Price multiplied by the initially registered and, if applicable,
     subsequently registered Securities; provided, however, in no event shall
     this provision limit each Investor's right to convert its Convertible
     Debenture into unregistered Common Stock.

          (b) The Company will maintain the Registration Statement or
     post-effective amendment filed under this Section 3 effective under the
     Securities Act until the earlier of (i) the date that none of the
     Securities covered by such Registration Statement are or may become issued
     and outstanding, (ii) the date that all of the Securities have been sold
     pursuant to such Registration Statement, (iii) the date the Investors
     receive an opinion of counsel to the Company, which counsel shall be
     reasonably acceptable to the Investors, that the Securities may be sold
     under the provisions of Rule 144 without limitation as to volume, (iv) all
     Securities have been otherwise transferred to persons who may trade such
     shares without restriction under the Securities Act, and the Company has
     delivered a new certificate or other evidence of ownership for such
     securities not bearing a restrictive legend, or (v) three (3) years from
     the Effective Date.

          (c) All fees, disbursements and out-of-pocket expenses and costs
     incurred by the Company in connection with the preparation and filing of
     the Registration Statement under subparagraph 3(a) and in complying with
     applicable securities and Blue Sky laws (including, without limitation, all
     attorneys' fees of the Company) shall be borne by the Company. The
     Investors shall bear the cost of underwriting and/or brokerage discounts,
     fees and commissions, if any, applicable to the Securities being registered
     and the fees and expenses of their counsel. The Investors and their counsel
     shall have a reasonable period, not to exceed five (5) Trading Days, to
     review the proposed Registration Statement or any amendment thereto, prior
     to filing with the Commission, and the Company shall provide each Investor
     with copies of any comment letters received from the Commission with
     respect thereto within two (2) Trading Days of receipt thereof. The Company
     shall use its best efforts to qualify any of the securities for sale in
     such states as any Investor reasonably designates and shall furnish
     indemnification in the manner provided in Section 6 hereof. However, the
     Company shall not be required to qualify in

                                       3
<PAGE>

     any state which will require an escrow or other restriction relating to the
     Company and/or the sellers, or which will require the Company to qualify to
     do business in such state or require the Company to file therein any
     general consent to service of process. The Company at its expense will
     supply the Investors with copies of the applicable Registration Statement
     and the prospectus included therein and other related documents in such
     quantities as may be reasonably requested by the Investors.

          (d) The Company shall not be required by this Section 3 to include an
     Investor's Registrable Securities in any Registration Statement which is to
     be filed if, in the opinion of counsel for both the Investor and the
     Company (or, should they not agree, in the opinion of another counsel
     experienced in securities law matters acceptable to counsel for the
     Investor and the Company) the proposed offering or other transfer as to
     which such registration is requested is exempt from applicable federal and
     state securities laws and would result in all purchasers or transferees
     obtaining securities which are not "restricted securities", as defined in
     Rule 144 under the Securities Act.

          (e) In the event that (i) the Registration Statement is not filed by
     the Company in a timely manner as set forth in Section 3(a), (ii) the
     Registration Statement is not declared effective by the Commission within
     the period of time set forth in Section 3(b) herein, or within five (5)
     days of clearance by the Commission to request effectiveness, (iii) such
     Registration Statement is not maintained as effective by the Company for
     the period set forth in Section 3(b) above, or (iv) the additional
     registration statement referred to in Section 3(a) is not filed within 15
     calendar days or declared effective within 60 calendar days as set forth
     therein (each a "Registration Default") then the Company will pay each
     Investor (pro-rata on a monthly basis), for each Registration Default then
     in effect, as liquidated damages and not as a penalty, during any period in
     which a Registration Default is occurring, two percent (2%) per month of
     (i) the then outstanding principal amount of the Convertible Debentures,
     and (ii) the value of any outstanding Warrants (valued at the difference
     between the average closing bid price during the applicable month and the
     Exercise Price multiplied by the number of Warrant Shares the Warrants are
     exercisable into), held by such Investor until such Registration Default no
     longer exists ("Liquidated Damages"). Such payment of the Liquidated
     Damages shall be made to the Investors in cash, or, at the option of the
     Company, in registered shares of Common Stock (based on the Conversion
     Price (as defined in the Convertible Debenture)) on the Trading Day prior
     to the date of payment) on the last day of each month during which a
     Registration Default occurred or was continuing, without demand therefor by
     the Investor; provided, however, that the payment of the Liquidated Damages
     shall not relieve the Company from its obligations to register the
     Securities pursuant to this Section.

          If the Company does not remit the payment to the Investors as set
     forth above, the Company will pay the Investors reasonable costs of
     collection, including attorneys' fees, in addition to the Liquidated
     Damages. The registration of the Securities pursuant to this provision
     shall not affect or limit the Investors' other rights or remedies as set
     forth in this Agreement.

                                       4
<PAGE>

          (f) The Company shall be precluded from including in any registration
     statement which it is required to file pursuant to this Section 3 any other
     securities apart from the Registrable Securities, without the prior written
     consent of a majority in interest of the Investors.

          (g) If at any time or from time to time after the effective date of
     any Registration Statement, the Company notifies the Investors in writing
     of the existence of a Potential Material Event (as defined in Section 3(h)
     below), the Investors shall not offer or sell any Securities or engage in
     any other transaction involving or relating to Securities, from the time of
     the giving of notice with respect to a Potential Material Event until the
     Investors receive written notice from the Company that such Potential
     Material Event either has been disclosed to the public or no longer
     constitutes a Potential Material Event; provided, however, that the Company
     may not so suspend the right to such holders of Securities for more than
     twenty (20) calendar days in the aggregate during any twelve month period,
     during the period the Registration Statement is required to be in effect,
     and if such period is exceeded, such event shall be a Registration Default
     and subject to liquidated damages as set forth in Section 3(e) hereof. If a
     Potential Material Event shall occur prior to the date a Registration
     Statement is required to be filed, then the Company's obligation to file
     such Registration Statement shall be delayed without penalty for not more
     than twenty (20) days, and such delay or delays shall not constitute a
     Registration Default. Such twenty (20) day period shall not be in addition
     to the twenty (20) day period allowed during the period the Registration
     Statement is required to be in effect. The Company must give the Investors
     notice in writing prior to the first day of the blackout period immediately
     upon knowledge that such a blackout period will occur and such notice must
     be acknowledged in writing by the Investors. Failure to provide the
     Investors with such notice shall constitute a Registration Default during
     the entire applicable period that the Registration Statement is suspended.
     Compliance by the Company with this Section 3(g) will not result in or be
     deemed a breach of any of the Company's obligations set forth in the
     Purchase Agreement not to disclose non-public information to the Investors.

          (h) "Potential Material Event" means any of the following: (a) the
     possession by the Company of material information not ripe for disclosure
     in a registration statement, as determined in good faith by the Chief
     Executive Officer or the Board of Directors of the Company that disclosure
     of such information in a Registration Statement would be detrimental to the
     business and affairs of the Company; or (b) any material engagement or
     activity by the Company which would, in the good faith determination of the
     Chief Executive Officer or the Board of Directors of the Company, be
     adversely affected by disclosure in a registration statement at such time,
     which determination shall be accompanied by a good faith determination by
     the Chief Executive Officer or the Board of Directors of the Company that
     the applicable Registration Statement would be materially misleading absent
     the inclusion of such information.

     Section 4. Cooperation with Company. The Investors will cooperate with the
Company in all respects in connection with this Agreement, including timely
supplying all information reasonably requested by the Company (which shall
include all information regarding

                                       5
<PAGE>

the Investors and proposed manner of sale of the Registrable Securities required
to be disclosed in any Registration Statement) and executing and returning all
documents reasonably requested in connection with the registration and sale of
the Registrable Securities and entering into and performing their obligations
under any underwriting agreement, if the offering is an underwritten offering,
in usual and customary form, with the managing underwriter or underwriters of
such underwritten offering. Nothing in this Agreement shall obligate any
Investor to consent to be named as an underwriter in any Registration Statement.
The obligation of the Company to register the Registrable Securities shall be
absolute and unconditional as to those Securities which the Commission will
permit to be registered without naming the Investors as underwriters. Any delay
or delays caused by the Investors by failure to cooperate as required hereunder
shall not constitute a Registration Default.

     Section 5. Registration Procedures. If and whenever the Company is required
by any of the provisions of this Agreement to effect the registration of any of
the Registrable Securities under the Act, the Company shall (except as otherwise
provided in this Agreement), as expeditiously as possible, subject to the
Investors' assistance and cooperation as reasonably required with respect to
each Registration Statement:

          (a) (i) prepare and file with the Commission 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 the provisions of the Act with
     respect to the sale or other disposition of all Registrable Securities
     covered by such Registration Statement whenever the Investors shall desire
     to sell or otherwise dispose of the same (including prospectus supplements
     with respect to the sales of Registrable Securities from time to time in
     connection with a registration statement pursuant to Rule 415 promulgated
     under the Act) and (ii) take all lawful action such that each of (A) the
     Registration Statement and any amendment thereto does not, when it becomes
     effective, contain an untrue statement of a material fact or omit to state
     a material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading and (B) the prospectus forming part of the
     Registration Statement, and any amendment or supplement thereto, does not
     at any time during the Registration Period include an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading;

          (b) (i) prior to the filing with the Commission of any Registration
     Statement (including any amendments thereto) and the distribution or
     delivery of any prospectus (including any supplements thereto), provide
     draft copies thereof to the Investors as required by Section 3(c) and
     reflect in such documents all such comments as the Investors (and their
     counsel) reasonably may propose respecting the Selling Shareholders and
     Plan of Distribution sections (or equivalents); (ii) furnish to each
     Investor such numbers of copies of a prospectus including a preliminary
     prospectus or any amendment or supplement to any prospectus, as applicable,
     in conformity with the requirements of the Act, and such other documents,
     as such Investor may reasonably request in order to facilitate the public
     sale or other disposition of the Registrable Securities owned by such

                                       6
<PAGE>

     Investor; and (iii) provide to each Investor copies of any comments and
     communications from the Commission relating to the Registration Statement,
     if lawful to do so;

          (c) register and qualify the Registrable Securities covered by the
     Registration Statement under such other securities or blue sky laws of such
     jurisdictions as the Investors shall reasonably request (subject to the
     limitations set forth in Section 3(c) above), and do any and all other acts
     and things which may be necessary or advisable to enable each Investor to
     consummate the public sale or other disposition in such jurisdiction of the
     Registrable Securities owned by such Investor;

          (d) list such Registrable Securities on the Principal Market, if the
     listing of such Registrable Securities is then permitted under the rules of
     such Principal Market;

          (e) notify each Investor at any time when a prospectus relating
     thereto covered by the Registration Statement is required to be delivered
     under the Act, of the happening of any event of which it has knowledge as a
     result of which the prospectus included in the Registration Statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing, subject to Section 3(g), and the Company shall prepare and
     file a curative amendment under Section 5(a) as quickly as commercially
     possible and during such period, the Investors shall not make any sales of
     Registrable Securities pursuant to the Registration Statement and during
     such period; provided, however, any period during which the Investors are
     precluded from making sales of the Registrable Securities shall be included
     in the 20 calendar day period in Section 3(g) and any such days herein
     which exceed, or cause the Company to exceed, such 20 calendar day period
     shall be deemed a Registration Default and the Company shall be subject to
     Liquidated Damages as set forth in Section 3(e).

          (f) as promptly as practicable after becoming aware of such event,
     notify each Investor who holds Registrable Securities being sold (or, in
     the event of an underwritten offering, the managing underwriters) of the
     issuance by the Commission of any stop order or other suspension of the
     effectiveness of the Registration Statement at the earliest possible time
     and take all lawful action to effect the withdrawal, recession or removal
     of such stop order or other suspension;

          (g) cooperate with the Investors to facilitate the timely preparation
     and delivery of certificates for the Registrable Securities to be offered
     pursuant to the Registration Statement and enable such certificates for the
     Registrable Securities to be in such denominations or amounts, as the case
     may be, as the Investors reasonably may request and registered in such
     names as the Investors may request; and, within three (3) Trading Days
     after a Registration Statement which includes Registrable Securities is
     declared effective by the Commission, deliver and cause legal counsel
     selected by the Company to deliver to the transfer agent for the
     Registrable Securities (with copies to the Investors) an appropriate
     instruction and, to the extent necessary, an opinion of such counsel;

                                       7
<PAGE>

          (h) take all such other lawful actions reasonably necessary to
     expedite and facilitate the disposition by the Investors of their
     Registrable Securities in accordance with the intended methods therefor
     provided in the prospectus which are customary for issuers to perform under
     the circumstances;

          (i) in the event of an underwritten offering, promptly include or
     incorporate in a prospectus supplement or post-effective amendment to the
     Registration Statement such information as the managers reasonably agree
     should be included therein and to which the Company does not reasonably
     object and make all required filings of such prospectus supplement or
     post-effective amendment as soon as practicable after it is notified of the
     matters to be included or incorporated in such Prospectus supplement or
     post-effective amendment; and

          (j) maintain a transfer agent and registrar for its Common Stock.

     Section 6. Indemnification.

          (a) To the maximum extent permitted by law, the Company agrees to
     indemnify and hold harmless the Investors and each person, if any, who
     controls an Investor within the meaning of the Securities Act (each a
     "Distributing Investor") against any losses, claims, damages or
     liabilities, joint or several (which shall, for all purposes of this
     Agreement, include, but not be limited to, all reasonable costs of defense
     and investigation and all reasonable attorneys' fees and expenses), to
     which the Distributing Investor may become subject, under the Securities
     Act or otherwise, insofar as such losses, claims, damages or liabilities
     (or actions in respect thereof) arise out of or are based upon any untrue
     statement or alleged untrue statement of any material fact contained in any
     Registration Statement, or any related final prospectus or amendment or
     supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading;
     provided, however, that the Company will not be liable in any such case to
     the extent, and only to the extent, that any such loss, claim, damage or
     liability arises out of or is based upon an untrue statement or alleged
     untrue statement or omission or alleged omission made in such Registration
     Statement, preliminary prospectus, final prospectus or amendment or
     supplement thereto in reliance upon, and in conformity with, written
     information furnished to the Company by the Distributing Investor, its
     counsel, affiliates or any underwriter, specifically for use in the
     preparation thereof or (ii) by such Investor's failure to deliver to the
     purchaser a copy of the most recent prospectus (including any amendments or
     supplements thereto. This indemnity agreement will be in addition to any
     liability, which the Company may otherwise have.

          (b) To the maximum extent permitted by law, each Distributing Investor
     agrees that it will indemnify and hold harmless the Company, and each
     officer and director of the Company or person, if any, who controls the
     Company within the meaning of the Securities Act, against any losses,
     claims, damages or liabilities (which shall, for

                                       8
<PAGE>

     all purposes of this Agreement, include, but not be limited to, all
     reasonable costs of defense and investigation and all reasonable attorneys'
     fees and expenses) to which the Company or any such officer, director or
     controlling person may become subject under the Securities Act or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions in respect thereof) arise out of or are based upon any untrue
     statement or alleged untrue statement of any material fact contained in any
     Registration Statement, or any related final prospectus or amendment or
     supplement thereto, or arise out of or are based upon the omission or the
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, but in
     each case only to the extent that such untrue statement or alleged untrue
     statement or omission or alleged omission was made in such Registration
     Statement, final prospectus or amendment or supplement thereto in reliance
     upon, and in conformity with, written information furnished to the Company
     by such Distributing Investor, its counsel, affiliates or any underwriter,
     specifically for use in the preparation thereof. This indemnity agreement
     will be in addition to any liability, which the Distributing Investor may
     otherwise have. Notwithstanding anything to the contrary herein, the
     Distributing Investor shall be liable under this Section 6(b) for only that
     amount as does not exceed the net proceeds to such Distributing Investor as
     a result of the sale of Registrable Securities pursuant to the Registration
     Statement.

          (c) Promptly after receipt by an indemnified party under this Section
     6 of notice of the commencement of any action against such indemnified
     party, such indemnified party will, if a claim in respect thereof is to be
     made against the indemnifying party under this Section 6, notify the
     indemnifying party in writing of the commencement thereof; but the omission
     so to notify the indemnifying party will not relieve the indemnifying party
     from any liability which it may have to any indemnified party except to the
     extent the failure of the indemnified party to provide such written
     notification actually prejudices the ability of the indemnifying party to
     defend such action. In case any such action is brought against any
     indemnified party, and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party will be entitled to
     participate in, and, to the extent that it may wish, jointly with any other
     indemnifying party similarly notified, assume the defense thereof, subject
     to the provisions herein stated and after notice from the indemnifying
     party to such indemnified party of its election so to assume the defense
     thereof, the indemnifying party will not be liable to such indemnified
     party under this Section 6 for any legal or other expenses subsequently
     incurred by such indemnified party in connection with the defense thereof
     other than reasonable costs of investigation, unless the indemnifying party
     shall not pursue the action to its final conclusion. The indemnified
     parties as a group shall have the right to employ one separate counsel in
     any such action and to participate in the defense thereof, but the fees and
     expenses of such counsel shall not be at the expense of the indemnifying
     party if the indemnifying party has assumed the defense of the action with
     counsel reasonably satisfactory to the indemnified party unless (i) the
     employment of such counsel has been specifically authorized in writing by
     the indemnifying party, or (ii) the named parties to any such action
     (including any impleaded parties) include both the indemnified party and
     the indemnifying party and the indemnified party shall have been advised by
     its counsel that there may be one or more legal defenses available to the

                                       9
<PAGE>

     indemnifying party different from or in conflict with any legal defenses
     which may be available to the indemnified party or any other indemnified
     party (in which case the indemnifying party shall not have the right to
     assume the defense of such action on behalf of such indemnified party, it
     being understood, however, that the indemnifying party shall, in connection
     with any one such action or separate but substantially similar or related
     actions in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable only for the reasonable fees and
     expenses of one separate firm of attorneys for the indemnified party, which
     firm shall be designated in writing by the indemnified party). No
     settlement of any action against an indemnified party shall be made without
     the prior written consent of the indemnified party, which consent shall not
     be unreasonably withheld so long as such settlement includes a full release
     of claims against the indemnified party.

          All fees and expenses of the indemnified party (including reasonable
     costs of defense and investigation in a manner not inconsistent with this
     Section and all reasonable attorneys' fees and expenses) shall be paid to
     the indemnified party, as incurred, within ten (10) Trading Days of written
     notice thereof to the indemnifying party; provided, that the indemnifying
     party may require such indemnified party to undertake to reimburse all such
     fees and expenses to the extent it is finally judicially determined that
     such indemnified party is not entitled to indemnification hereunder.

     Section 7. Contribution. In order to provide for just and equitable
contribution under the Securities Act in any case in which (i) the indemnified
party makes a claim for indemnification pursuant to Section 6 hereof but is
judicially determined (by the 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 the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified party, then the Company and the
applicable Distributing Investor shall contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (which shall, for
all purposes of this Agreement, include, but not be limited to, all reasonable
costs of defense and investigation and all reasonable attorneys' fees and
expenses), in either such case (after contribution from others) on the basis of
relative fault as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the applicable Distributing Investor on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Distributing Investor agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to in this Section 7. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section 7
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the

                                       10
<PAGE>

Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

     Notwithstanding any other provision of this Section 7, in no event shall
any (i) Investor be required to undertake liability to any person under this
Section 7 for any amounts in excess of the dollar amount of the proceeds
received by such Investor from the sale of such Investor's Registrable
Securities (after deducting any fees, discounts and commissions applicable
thereto) pursuant to any Registration Statement under which such Registrable
Securities are registered under the Securities Act and (ii) underwriter be
required to undertake liability to any person hereunder for any amounts in
excess of the aggregate discount, commission or other compensation payable to
such underwriter with respect to the Registrable Securities underwritten by it
and distributed pursuant to such Registration Statement.

     Section 8. Notices. All notices, demands, requests, consents, approvals,
and other communications required or permitted hereunder shall be in writing
and, unless otherwise specified herein, shall be (i) hand delivered, (ii)
deposited in the mail, registered or certified, return receipt requested,
postage prepaid, (iii) delivered by reputable air courier service with charges
prepaid, or (iv) transmitted by facsimile, addressed as set forth in the
Purchase Agreement or to such other address as such party shall have specified
most recently by written notice. Any notice or other communication required or
permitted to be given hereunder shall be deemed effective (a) upon hand delivery
or delivery by facsimile, with accurate confirmation generated by the
transmitting facsimile machine, at the address or number designated below (if
delivered on a business day during normal business hours where such notice is to
be received), or the first business day following such delivery (if delivered
other than on a business day during normal business hours where such notice is
to be received) or (b) on the first business day following the date of sending
by reputable courier service, fully prepaid, addressed to such address, or (c)
upon actual receipt of such mailing, if mailed. Either party hereto may from
time to time change its address or facsimile number for notices under this
Section 8 by giving at least ten (10) days' prior written notice of such changed
address or facsimile number to the other party hereto.

     Section 9. Assignment. This Agreement is binding upon and inures to the
benefit of the parties hereto and their respective heirs, successors and
permitted assigns. The rights granted the Investors under this Agreement may be
assigned to any purchaser of substantially all of the Registrable Securities (or
the rights thereto) from an Investor, as otherwise permitted by the Purchase
Agreement.

     Section 10. Additional Covenants of the Company. The Company agrees that at
any time that the Registration Statement is on Form S-3, for so long as it shall
be required to maintain the effectiveness of such registration statement, it
shall file all reports and information required to be filed by it with the
Commission in a timely manner and take all such other action so as to maintain
such eligibility for the use of such form.

     Section 11. Counterparts/Facsimile. This Agreement may be executed in two
or more counterparts, each of which shall constitute an original, but all of
which, when together shall constitute but one and the same instrument, and shall
become effective when one or more

                                       11
<PAGE>

counterparts have been signed by each party hereto and delivered to the other
parties. In lieu of the original, a facsimile transmission or copy of the
original shall be as effective and enforceable as the original.

     Section 12. Remedies. The remedies provided in this Agreement are
cumulative and not exclusive of any remedies provided by law. If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and the parties hereto shall use their best efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term, provision, covenant or restriction.

     Section 13. Conflicting Agreements. The Company shall not enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the holders of Registrable Securities in this Agreement or otherwise
prevents the Company from complying with all of its obligations hereunder.

     Section 14. Headings. The headings in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

     Section 15. Governing Law, Arbitration. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. The Company and each of the
Investors agree to submit themselves to the in personam jurisdiction of the
state and federal courts situated within the Southern District of the State of
New York with regard to any controversy arising out of or relating to this
Agreement. The non-prevailing party to any dispute hereunder shall pay the
expenses of the prevailing party, including reasonable attorneys' fees, in
connection with any such dispute.

                                ESCROW AGREEMENT

     THIS ESCROW AGREEMENT (this "Agreement") is made as of March 29, 2001, by
and among World Wide Wireless Communications, Inc., a corporation incorporated
under the laws of the State of Nevada (the "Company"), the investors signatory
hereto (each an "Investor" and together the "Investors"), and Epstein Becker &
Green, P.C., (the "Escrow Agent"). Capitalized terms used but not defined herein
shall have the meanings set forth in the Purchase Agreement referred to in the
first recital.

                              W I T N E S S E T H:

     WHEREAS, the Investors will be purchasing from the Company convertible
debentures with an aggregate principal amount of $750,000 (the "Convertible
Debentures") and Warrants at the Purchase Price set forth in the Senior Secured
Convertible Debenture and Warrants Purchase Agreement (the "Purchase Agreement")
dated the date hereof between the Investors and the Company, which will be
issued as per the terms contained herein and in the Purchase Agreement; and

     WHEREAS, it is intended that the purchase of the securities be consummated
in accordance with the requirements set forth by Sections 4(2) and/or 4(6)
and/or Regulation D promulgated under the Securities Act of 1933, as amended;
and

     WHEREAS, the Company and the Investors have requested that the Escrow Agent
hold the Purchase Price with respect to the Closing in escrow until the Escrow
Agent has received the certificates representing the Convertible Debentures, the
Warrants and certain other closing documents specified herein;

     NOW, THEREFORE, in consideration of the covenants and mutual promises
contained herein and other good and valuable consideration, the receipt and
legal sufficiency of which are hereby acknowledged and intending to be legally
bound hereby, the parties agree as follows:

                                   ARTICLE 1
                               TERMS OF THE ESCROW

     1.1.   The parties hereby agree to establish an escrow account with the

the $750,000 principal amount of Convertible Debentures and the Warrants at the
Closing as contemplated by the Purchase Agreement.

     1.2.   Delivery of Purchase Price.

            (a)   At the Closing, upon the Escrow Agent's receipt of the
                  Purchase Price for the Closing into its master escrow account,
                  together with executed counterparts of this Agreement, the
                  Purchase Agreement

<PAGE>

                  and the Registration Rights Agreement, it shall telephonically
                  advise the Company, or the Company's designated attorney or
                  agent, of the amount of funds it has received into its master
                  escrow account.

            (b)   Wire transfers to the Escrow Agent shall be made as follows:

                  Epstein Becker & Green, P.C.
                  Master Escrow Account
                  Chase Manhattan Bank
                  1411 Broadway - Fifth Floor
                  New York, New York  10018
                  ABA No. 021000021
                  Account No. 035-1-346036
                  Attention:  L. Borneo

     1.3.   Obligations of the Company. The Company, upon receipt of said
notice, shall deliver to the Escrow Agent the certificates representing the
Convertible Debentures evidencing in the aggregate the $750,000 principal amount
of Convertible Debentures and the Warrants to be issued to each Investor at the
Closing together with:

            (a)   the original executed Registration Rights Agreement
                  substantially in the form of Exhibit B to the Purchase
                  Agreement;

            (b)   the original executed Instructions to Transfer Agent
                  substantially in the form of Exhibit F to the Purchase
                  Agreement;

            (c)   the original executed opinion of Foley & Lardner in the form
                  of Exhibit D to the Purchase Agreement;

            (d)   the original executed Security Documents and, if required to

                  of all filed UCC-1;

            (e)   an original counterpart of this Escrow Agreement; and

            (f)   original counterparts to the Side Letters for each Investor.

     In the event that the foregoing items are not in the Escrow Agent's
possession within three (3) Trading Days of the Escrow Agent notifying the
Company that the Escrow Agent has custody of the Purchase Price applicable to
such Convertible Debentures, then each Investor shall have the right to demand
the return of said Purchase Price.

     1.4.   At the Closing, once Escrow Agent confirms the validity of the
issuance of the applicable Convertible Debentures and the Warrants by means of
its receipt of a Release Notice in the form attached hereto as Exhibit X
executed by the Company and each Investor, it shall calculate and enter the
number, exercise price, issuance date and termination date on the face of the
Warrants and insert the set price and

                                       2
<PAGE>

issuance date on each Convertible Debenture and then wire that amount of funds
necessary to purchase the applicable Convertible Debentures and the Warrants per
the written instructions of the Company, net of $25,000 to Epstein Becker &
Green for Investor's legal, administrative and escrow costs and net of 8% of the
Purchase Price as directed by Union Atlantic, L.C.

      Once the funds (as set forth above) have been sent per the Company's
instructions, the Escrow Agent shall then arrange to have the Convertible
Debentures, the Warrants, the Registration Rights Agreement, the Escrow
Agreement, the Security Documents and the opinion of counsel delivered as per
instructions from the Investor, deliver the Instructions to Transfer Agent to
the Transfer Agent.

                                   ARTICLE 2
                                  MISCELLANEOUS

     2.1.  No waiver or any breach of any covenant or provision herein contained
shall be deemed a waiver of any preceding or succeeding breach thereof, or of
any other covenant or provision herein contained. No extension of time for
performance of any obligation or act shall be deemed any extension of the time
for performance of any other obligation or act.

     2.2.   All notices or other communications required or permitted hereunder
shall be in writing, and shall be sent as set forth in the Purchase Agreement.

     2.3.   This Escrow Agreement shall be binding upon and shall inure to the
benefit of the permitted successors and permitted assigns of the parties hereto.

     2.4.   This Escrow Agreement is the final expression of, and contains the
entire agreement between, the parties with respect to the subject matter hereof
and supersedes all prior understandings with respect thereto. This Escrow
Agreement may not be modified, changed, supplemented or terminated, nor may any
obligations hereunder be waived, except by written instrument signed by the
parties to be charged or by its agent duly authorized in writing or as otherwise
expressly permitted herein.

     2.5.   Whenever required by the context of this Escrow Agreement, the
singular shall include the plural and masculine shall include the feminine. This
Escrow Agreement shall not be construed as if it had been prepared by one of the
parties, but rather as if both parties had prepared the same. Unless otherwise
indicated, all references to Articles are to this Escrow Agreement.

     2.6.   The parties hereto expressly agree that this Escrow Agreement shall
be governed by, interpreted under and construed and enforced in accordance with
the laws of the State of New York. Any action to enforce, arising out of, or
relating in any way to, any provisions of this Escrow Agreement shall only be
brought in a state or Federal court sitting in New York City.

                                       3
<PAGE>

     2.7.   The Escrow Agent's duties hereunder may be altered, amended,
modified or revoked only by a writing signed by the Company, each Investor and
the Escrow Agent.

     2.8.   The Escrow Agent shall be obligated only for the performance of such
duties as are specifically set forth herein and may rely and shall be protected
in relying or refraining from acting on any instrument reasonably believed by
the Escrow Agent to be genuine and to have been signed or presented by the
proper party or parties. The Escrow Agent shall not be personally liable for any
act the Escrow Agent may do or omit to do hereunder as the Escrow Agent while
acting in good faith, and any act done or omitted by the Escrow Agent pursuant
to the advice of the Escrow Agent's attorneys-at-law shall be conclusive
evidence of such good faith.

     2.9.   The Escrow Agent is hereby expressly authorized to disregard any and
all warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree, the Escrow Agent shall not be liable to any of the parties hereto or
to any other person, firm or corporation by reason of such decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have
been entered without jurisdiction.

     2.10.  The Escrow Agent shall not be liable in any respect on account of
the identity, authorization or rights of the parties executing or delivering or
purporting to execute or deliver the Purchase Agreement or any documents or
papers deposited or called for thereunder.

     2.11.  The Escrow Agent shall be entitled to employ such legal counsel and
other experts as the Escrow Agent may deem necessary properly to advise the
Escrow Agent in connection with the Escrow Agent's duties hereunder, may rely
upon the advice of such counsel, and may pay such counsel reasonable
compensation therefor. The Escrow Agent has acted as legal counsel for the
Investors, and may continue to act as legal counsel for the Investors, from time
to time, notwithstanding its duties as the Escrow Agent hereunder. The Company
consents to the Escrow Agent in such capacity as legal counsel for the Investors
and waives any claim that such representation represents a conflict of interest
on the part of the Escrow Agent. The Company understands that the Investors and
the Escrow Agent are relying explicitly on the foregoing provision in entering
into this Escrow Agreement.

     2.12.  The Escrow Agent's responsibilities as escrow agent hereunder shall
terminate if the Escrow Agent shall resign by written notice to the Company and
the Investors. In the event of any such resignation, the Investors and the
Company shall appoint a successor Escrow Agent.

     2.13.  If the Escrow Agent reasonably requires other or further instruments
in connection with this Escrow Agreement or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

                                       4
<PAGE>

     2.14.  It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the documents
or the escrow funds held by the Escrow Agent hereunder, the Escrow Agent is
authorized and directed in the Escrow Agent's sole discretion (1) to retain in
the Escrow Agent's possession without liability to anyone all or any part of
said documents or the escrow funds until such disputes shall have been settled
either by mutual written agreement of the parties concerned by a final order,
decree or judgment or a court of competent jurisdiction after the time for
appeal has expired and no appeal has been perfected, but the Escrow Agent shall
be under no duty whatsoever to institute or defend any such proceedings or (2)
to deliver the escrow funds and any other property and documents held by the
Escrow Agent hereunder to a state or Federal court having competent subject
matter jurisdiction and located in the City of New York in accordance with the
applicable procedure therefor.

     2.15.  The Company and each Investor agree jointly and severally to
indemnify and hold harmless the Escrow Agent and its partners, employees, agents
and representatives from any and all claims, liabilities, costs or expenses in
any way arising from or relating to the duties or performance of the Escrow
Agent hereunder or the transactions contemplated hereby or by the Purchase
Agreement other than any such claim, liability, cost or expense to the extent
the same shall have been determined by final, unappealable judgment of a court
of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Escrow Agent.
