            (a) Mobility shall deliver to each Investor: (i) a copy of the
      irrevocable instruction letter to Mobility's transfer agent instructing
      such transfer agent to register the issuance and ownership of the Shares
      to each Investor in the stockholders' registry and records of Mobility,
      and issue to each Investor a certificate evidencing ownership of such

      of immediately available funds to an account designated by Mobility.

3.    OTHER COVENANTS AND AGREEMENTS

      3.1 Lock-Up Agreements. Each Investor hereby agrees that during the
Lock-Up Period, such Investor will not, and will not cause or permit an
Affiliate of such Investor to, without the prior written approval of Mobility
(which consent may be withheld or delayed in the sole discretion of Mobility),
directly or indirectly, sell, offer to sell, contract to sell (including without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose of any Shares (it being understood that the term "Shares"
specifically excludes the Underlying Shares).

      3.2 Restrictions on Certain Activities. As long as an Investor or its
Affiliates owns any Shares, Warrants or Underlying Shares, such Investor hereby
agrees that, without the prior written approval of Mobility, which approval may
be withheld or delayed in the sole discretion of Mobility, such Investor will
not, and will not cause or permit an Affiliate of such Investor to (i) acquire
any securities of Mobility (other than the acquisition of any Underlying Shares
upon exercise of the Warrants); and (ii) directly or indirectly lead or initiate
a Change of Control of Mobility.

      3.3 Registration Rights.

            (a) Shelf Registration.

                  (i) Prior to the expiration of the Lock-Up Period, Mobility
      will prepare and file or cause to be prepared and filed with the SEC a
      Registration Statement for an offering to be made on a delayed or
      continuous basis pursuant to Rule 415 of the Securities Act registering
      the resale from time to time by the Investors of the Registrable
      Securities. Mobility shall use its best efforts to cause the Registration
      Statement to be declared effective under the Securities Act as of the
      first anniversary of the Closing Date (the "Effectiveness Date"), and to
      keep such Registration Statement continuously effective under the
      Securities Act until the earlier of (A) the date that is the later of (I)
      the second anniversary of the Effectiveness Date and (II) with respect to
      a particular Investor, the date that neither such Investor nor any of its
      Affiliates is an Affiliate of Mobility, (B) such date as all unsold
      securities held by the Investors and registered on such Registration
      Statement may be sold in a single three-month period in accordance with
      Rule 144 under the Securities Act or (C) such date as all securities
      registered on such Registration Statement have been resold (the earlier to
      occur of (A), (B) and (C) is the "Effectiveness Termination Date"). At the
      time the Registration Statement is declared effective, each Investor shall
      be named as a selling securityholder in the Registration Statement and the
      related prospectus

                                       2
<PAGE>
      in such a manner as to permit such Investor to deliver such prospectus to
      purchasers of registered securities in accordance with applicable law.

                  (ii) In the event that the Registration Statement is not
      declared effective by the SEC under the Securities Act by the
      Effectiveness Date, Mobility shall pay to each Investor an amount in cash
      equal to one-half of a percent (0.5%) of the aggregate purchase price paid
      by such Investor for the Shares pursuant to Section 2.1(a) hereof for each
      30-day period thereafter until the Registration Statement is declared
      effective.

      (b) Selling Procedure.

                  (i) Following the date that the Registration Statement is
      declared effective by the SEC, each Investor shall be permitted, subject
      to the other provisions hereof, to offer and sell the Registrable
      Securities included thereon in the manner described in such Registration
      Statement during the period of its effectiveness; provided, however, that
      such Investor arranges for delivery of a current prospectus to the
      transferee of the Registrable Securities.

                  (ii) Notwithstanding the foregoing, or anything contained in
      this Agreement to the contrary, Mobility may suspend offers and sales of
      Registrable Securities pursuant to such Registration Statement if in the
      good faith judgment of the Board after consultation with counsel,
      (A)(I)(a) such registration would be substantially contrary to the best
      interests of Mobility because (1) it would materially interfere with a
      material financing plan or other material transaction or negotiations
      relating thereto then pending, or (2) it would require the disclosure of
      any material non-public information prior to the time that such
      information would otherwise be disclosed or be required to be disclosed,
      if such early disclosure would be substantially contrary to the best
      interests of Mobility, or (b) such Registration Statement contains or may
      contain an untrue statement of material fact or omits or may omit to state
      a material fact required to be stated therein or necessary to make the
      statements therein not misleading, and (II) the Board concludes, as a
      result, that it is necessary and appropriate to defer the filing of such
      Registration Statement at such time, and (B) Mobility shall furnish to the
      Investor a certificate signed by the President or Chief Executive Officer
      of Mobility stating the good faith judgment of the Board to such effect,
      then Mobility shall have the right to defer such filing only for the
      period during which such filing would be substantially contrary to the
      best interests of Mobility (a "Suspension"); provided, however, that the
      aggregate number of days included in such periods of Suspension shall not
      exceed ninety (90) days in any twelve (12) month period. In the event of
      any Suspension, each Investor shall discontinue disposition of Registrable
      Securities covered by the Registration Statement until copies of a
      supplemented or amended prospectus are distributed to such Investor or
      until such Investor is advised in writing by Mobility that the use of the
      applicable prospectus may be resumed.

            (c) Expenses of Registration. All Registration Expenses incurred in
connection with the registrations pursuant to this Section 3.3 shall be borne by
Mobility. All Selling Expenses incurred in connection with any registrations
hereunder shall be borne by the Investors.

            (d) Registration Procedures.

                  (i) In the case of a registration, and any qualification or
      compliance effected by Mobility pursuant to this Section 3.3, Mobility
      shall keep the Investors advised in writing as to the initiation of such
      registration, qualification and compliance and as to the completion
      thereof. Subject to the provisions hereof, and until the Effectiveness
      Termination Date, Mobility shall take the following actions:

                                       3
<PAGE>
                  (1) Prepare and file with the SEC the Registration Statement
            in accordance with Section 3.3(a)) above;

                  (2) Furnish to each Investor such reasonable numbers of copies
            of a prospectus, including a preliminary prospectus, in conformity
            with the requirements of the Securities Act, and such other
            documents as such Investor may reasonably request in order to
            facilitate the disposition of Registrable Securities owned by it;

                  (3) Use commercially reasonable efforts to register and
            qualify the securities covered by such registration statement under
            such other securities or Blue Sky laws of such jurisdictions as
            shall be reasonably requested by an Investor for the purpose of
            permitting the offers and sales of the securities in such
            jurisdictions, provided that Mobility shall not be required in
            connection therewith or as a condition thereto to qualify to do
            business or to file a general consent to service of process in any
            such states or jurisdictions;

                  (4) Notify, as soon as reasonably practicable after Mobility
            becomes aware, each Investor at any time when a prospectus relating
            thereto is required to be delivered under the Securities Act of the
            happening of any event as a result of which the prospectus included
            in such 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;

                  (5) If for any reason it shall be necessary to amend or
            supplement the Registration Statement or the prospectus used in
            connection with such Registration Statement in order to correct any
            untrue statements, ensure that the Registration Statement is not
            misleading or otherwise to comply with the Securities Act, as
            promptly as reasonably practicable, prepare and file with the SEC
            such amendments and supplements to such Registration Statement and
            the prospectus as may be necessary to correct such untrue
            statements, ensure that such Registration Statement is not
            misleading or to comply with the provisions of the Securities Act,
            provided, that to the extent that any statements to be corrected
            relate to any information provided by an Investor, Mobility shall
            not be obligated to amend the Registration Statement until Mobility
            has received such corrected information from such Investor and has
            had a reasonable opportunity to amend or supplement such
            Registration Statement or prospectus;

                  (6) If the Registration Statement ceases to be effective for
            any reason at any time prior to the Effectiveness Termination Date
            (other than because all securities registered thereunder have been
            resold pursuant thereto), use its best efforts to obtain the prompt
            withdrawal of any order suspending the effectiveness thereof;

                  (7) Cause all such Registrable Securities registered hereunder
            to be listed or included on each securities exchange or automated
            quotation system on which similar securities issued by Mobility are
            then listed or included; and

                  (8) Provide a transfer agent and registrar for all Registrable
            Securities registered hereunder and a CUSIP number for all such
            Registrable Securities, in each case not later than the effective
            date of such registration.

                                       4
<PAGE>
In addition, in the event of any underwritten public offering, Mobility shall
(I) enter into and perform its obligations under an underwriting agreement, in
usual and customary form, with the managing underwriter of such offering,
provided that each Investor shall also enter into and perform its obligations
under such an agreement, and (II) use its best efforts to furnish, at the
request of an Investor, on the date that such Registrable Securities are
delivered to the underwriters for sale in connection with a registration
pursuant to this Section 3.3, (a) an opinion, dated as of the date of the
Registration Statement with respect to such securities becomes effective, of the
counsel representing Mobility for the purposes of such registration, in form and
substance as is customarily given in an underwritten public offering (and
reasonably acceptable to the counsel for the Investors), addressed to the
underwriters, if any, and to the Investors, and (b) a letter dated such date,
from the independent certified public accountants of Mobility, in form and
substance as is customarily given by independent certified public accountants in
an underwritten public offering (and reasonably acceptable to the counsel for
the Investor), addressed to the underwriters, to the extent such letter is
permitted under generally recognized accounting practice.

                  (ii) Mobility shall reasonably cooperate with the Investors in
      performing Mobility's obligations under this Section 3.3 and shall: (A)
      permit the Investors to review and comment upon any offering pursuant to
      this Section 3.3 and to review and comment upon (I) the Registration
      Statement prior to its filing with the SEC and (II) all amendments and
      supplements thereto (except for Annual Reports on Form 10-K, Quarterly
      Reports on Form 10-Q and Current Reports on Form 8-K and any similar or
      successor reports) prior to their filing with the SEC; and (B) furnish to
      each Investor, in accordance with Section 8.9 hereof and without charge,
      (1) any correspondence from the SEC or the staff of the SEC to Mobility or
      its representatives relating to any Registration Statement, (2) promptly
      after the same is prepared and filed with the SEC, one copy of any
      Registration Statement and any amendment(s) thereto, including financial
      statements and schedules, all documents incorporated therein by reference
      and all exhibits, and (3) upon the effectiveness of any Registration
      Statement, one copy of the prospectus included in such Registration
      Statement and all amendments and supplements thereto.

      (e)   Indemnification.

                  (i) Mobility shall indemnify each Investor, its respective
      officers, directors, employees, partners, affiliates, agents,
      representatives and legal counsel (including Investor Counsel), and each
      person controlling (or deemed controlling) such Investor within the
      meaning of the Securities Act, (collectively, the "Investor's Agents")
      with respect to which registration, qualification or compliance has been
      effected pursuant to this Section 3.3, against all claims, losses, damages
      and liabilities (or actions in respect thereof), joint or several, arising
      out of or based on (A) any untrue statement (or alleged untrue statement)
      of a material fact contained in any prospectus, offering circular or other
      similar document or any amendments or supplements thereto (including any
      related registration statement and amendments or supplements thereto,
      notification or the like) incident to any such registration, qualification
      or compliance, (B) 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 in the light of the circumstances under
      which they were made, or (C) any violation by Mobility of the Securities
      Act, the Exchange Act or any rule or regulation promulgated thereunder
      applicable to Mobility in connection with any such registration,
      qualification or compliance, and shall reimburse each Investor, and such
      Investor's Agents, for any legal and any other expenses reasonably
      incurred in connection with investigating or defending any such claim,
      loss, damage, liability or action, as incurred; provided, however, that
      Mobility shall not be liable in any such case to the extent that any such
      claim, loss, damage, liability or expense arises out of or is based on any
      untrue statement or omission based upon written information furnished to
      Mobility by an instrument duly executed by such Investor and stated to be
      specifically for use therein or furnished in writing by such Investor to
      Mobility in

                                       5
<PAGE>
      response to a request by Mobility stating specifically that such
      information shall be used by Mobility therein; provided further, however,
      that the indemnity agreement provided in this Section 3.3(e)(i) shall not
      apply to amounts paid in settlement of any such loss, claim, damage,
      liability or action if such settlement is effected without the prior
      written consent of Mobility, which consent shall not be unreasonably
      withheld, unless such consent is obtained in accordance with subsection
      (iii) hereof.

                  (ii) Each Investor shall, severally and not jointly, indemnify
      Mobility, its officers, directors, employees, affiliates, agents,
      representatives, and each person controlling Mobility within the meaning
      of the Securities Act (collectively, the "Mobility's Agents"), against all
      claims, losses, 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 prospectus, offering
      circular or other similar document or any amendments or supplements
      thereto (including any related registration statements and any amendments
      or supplements thereto, notification and the like) incident to any such
      registration, qualification or compliance, or (B) 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 in the light of
      the circumstances under which they were made, or (C) any violation by
      Investor of the Securities Act, the Exchange Act or any rule or regulation
      promulgated thereunder applicable to Investor in connection with any such
      registration, qualification or compliance, and shall reimburse Mobility
      and Mobility's Agents for any legal and any other expenses reasonably
      incurred in connection with investigating or defending any such claim,
      loss, damage, liability or action, as incurred, in each case to the
      extent, but only to the extent, that such untrue statement (or alleged
      untrue statement) or omission (or alleged omission) is made in such
      prospectus, offering circular or other similar document or any amendments
      or supplements thereto (including any related registration statements and
      any amendments or supplements thereto, notification and the like) in
      reliance upon and in conformity with written information furnished in
      writing to Mobility by an instrument duly executed by such Investor and
      stated to be specifically for use therein or furnished by such Investor to
      Mobility in response to a request by Mobility stating specifically that
      such information shall be used by Mobility therein; provided, however,
      that the indemnity agreement provided in this Section 3.3(e)(ii) shall not
      apply to amounts paid in settlement of any such loss, claim, damage,
      liability or action if such settlement is effected without the prior
      written consent of such Investor, which consent shall not be unreasonably
      withheld, unless such consent is obtained in accordance with subsection
      (iii) hereof. In no event shall an Investor's indemnification obligation
      exceed the net proceeds received from its sale of Registrable Securities
      in such offering.

                  (iii) Each party entitled to indemnification under this
      Section 3.3(e) (the "Indemnified Party") shall give written notice to the
      party required to provide indemnification (the "Indemnifying Party")
      promptly after such Indemnified Party has received written notice 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, however, that counsel for the
      Indemnifying Party, who shall conduct the defense of such claim or
      litigation, shall be approved by the Indemnified Party (whose approval
      shall not be unreasonably withheld). The Indemnified Party may participate
      in such defense at such party's expense; provided, however, that the
      Indemnifying Party shall bear the expense of such defense of the
      Indemnified Party if representation of both parties by the same counsel
      would be inappropriate due to actual or potential conflicts of interest.
      The failure of any Indemnified Party to give notice within a reasonable
      period of time as provided herein shall relieve the Indemnifying Party of
      its obligations under this Section 3.3(e), but only to the extent that
      such failure to give notice shall materially adversely prejudice the
      Indemnifying Party in the defense of any such claim or any such
      litigation. No Indemnifying Party, in the defense of any such claim or
      litigation, shall,

                                       6
<PAGE>
      except with the written consent of each Indemnified Party (which shall not
      be unreasonably withheld), 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.

                  (iv) If the indemnification provided for in this Section
      3.3(e) is held by a court of competent jurisdiction to be unavailable to
      an Indemnified Party with respect to any loss, liability, claim, damage or
      expense referred to therein, then the Indemnifying Party, in lieu of
      indemnifying such Indemnified Party hereunder, shall contribute to the
      amount paid or payable by such Indemnified Party as a result of such loss,
      liability, claim, damage, or expense in such proportion as is appropriate
      to reflect the relative fault of the Indemnifying Party on the one hand
      and of the Indemnified Party on the other in connection with the
      statements or omissions that resulted in such loss, liability, claim,
      damage or expense as well as any other relevant equitable considerations;
      provided, however, that in no event shall any contribution by an Investor
      under this Section 3.3(e) exceed the net proceeds from the offering
      received by such Investor. The relative fault of the Indemnifying Party
      and of the Indemnified Party shall be determined by reference to, among
      other things, whether the untrue or alleged untrue statement of a material
      fact or the omission to state a material fact relates to information
      supplied by the Indemnifying Party or by the Indemnified Party and the
      parties' relative intent, knowledge, access to information, and
      opportunity to correct or prevent such statement or omission.

                  (v) The obligations of Mobility and the Investors under this
      Section 3.3 shall survive the completion of any offering of the
      Registrable Securities in a Registration Statement under this Section 3.3,
      any investigation made by or on behalf of the Indemnified Party or any
      officer, director or controlling Person of such Indemnified Party and
      shall survive the transfer of securities.

            (f) Information by the Investor. As a condition precedent to the
      obligations of Mobility under this Section 3.3, each Investor shall
      furnish to Mobility all such information and materials regarding such
      Investor and the distribution proposed by such Investor as Mobility may
      reasonably request in writing in connection with any registration,
      qualification or compliance referred to in this Section 3.3. Each Investor
      will promptly notify Mobility in writing of any changes in the information
      set forth in the Registration Statement after it is prepared regarding the
      Investor or its plan of distribution to the extent required by applicable
      law.

            (g) Inclusion of Additional Securities. Mobility may include
      additional Mobility securities in any registration pursuant to this
      Section 3.3 for its own account and by other parties in amounts as
      determined by the Board, provided that any such inclusion does not (i)
      reduce the number of Registrable Securities (or other securities of the
      Investors) which are included in the registration statement filed pursuant
      to this Section 3.3 or otherwise materially and adversely affect the
      rights of the Investors hereunder, or (ii) cause Form S-3 to be
      unavailable under the Securities Act for such registration due to the
      nature of the additional securities to be so included.

            (h) Termination of Registration Rights. All rights and obligations
      provided for in this Section 3.3 (except for in Section 3.3(e), which
      rights and obligations shall survive) shall terminate on the date on which
      Mobility has no obligation to maintain the effectiveness of the
      Registration Statement.

      3.4 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Investors the benefits of Rule 144 promulgated under the
Securities Act ("SEC Rule 144") and any other

                                       7
<PAGE>
rule or regulation of the SEC that may at any time permit an Investor to sell
securities of Mobility to the public without registration or pursuant to a
registration on Form S-3, Mobility agrees to:

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

            (b) use its best efforts to take such action as is necessary to
      enable each Investor to utilize a Registration Statement for the sale of
      its Registrable Securities;

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

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

      3.5 Assignment of Rights. The rights to cause Mobility to register
Registrable Securities pursuant to Section 3.3 may be assigned by an Investor
only to its Affiliates. In the event of such assignment, the transferee shall
furnish to Mobility written notice of such assignment and agree in writing to be
bound by the obligations of such Investor hereunder.

      3.6 Nasdaq Listing. Mobility shall file a listing application with Nasdaq
for the Registrable Securities and use its best efforts to maintain the listing
of its Common Stock on Nasdaq (or a comparable system then in use) or the New
York Stock Exchange or other national exchange for a period of not less than
three years from the date of original issuance.

      3.7 Reasonable Efforts; Notification; Representations. Subject to the
other terms and conditions of this Agreement, each Party shall use reasonable
efforts to take promptly, or cause to be taken, all actions, and to do promptly,
or cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the Transactions. Each
Party shall give prompt notice to each other Party upon becoming aware that any
representation or warranty made by such party in this Agreement has become
untrue or inaccurate or that such party has failed to comply with or satisfy in
any material respect any covenant, condition or agreement to be complied with or
satisfied by such party under this Agreement.

4.    REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF MOBILITY

      As an inducement to the Investors to enter into this Agreement and to
consummate the Transactions, Mobility represents, warrants and agrees that:

      4.1 Organization and Authority. Mobility has all required corporate power
and authority to own its own properties and to carry on its business as
presently conducted. Mobility has all required power and authority to execute
and deliver this Agreement, to issue and sell the Securities (and the Underlying
Shares), and to carry out the Transactions. Mobility is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware, and is duly licensed or qualified and in good

                                       8
<PAGE>
standing as a foreign corporation in each jurisdiction where the properties
owned, leased, used or operated by it or the nature of the business conducted by
it require it to be so qualified.

      4.2 Authority. Mobility has all requisite corporate power and authority to
execute and deliver this Agreement and the Warrants, to perform its obligations
under this Agreement, and to consummate the Transactions. The execution and
delivery of this Agreement and the Warrants by Mobility and the performance by
Mobility of its obligations hereunder and thereunder and the consummation by
Mobility of the Transactions, have been duly authorized by Mobility's board of
directors and no other corporate action on the part of Mobility or its
stockholders is necessary to authorize the execution and delivery by Mobility of
this Agreement or the consummation by it of the Transactions (including, for
such purpose, the issuance of the Underlying Shares). This Agreement and the
Warrants have been duly executed and delivered by Mobility and constitute the
legal, valid and binding obligations of Mobility, enforceable in accordance with
their terms, except to the extent that the enforceability hereof and thereof may
be limited by bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally or by general principles of equity. None
of the execution or delivery of this Agreement or the Warrants, the performance
by Mobility of the terms hereof or thereof, or the consummation of the
Transactions (including, for such purpose, the issuance of the Underlying
Shares) (a) will result (upon notice, with lapse of time or otherwise) in a
breach of the terms or conditions of, a default under, a conflict with, or the
acceleration of (or the creation in any Person of any right to cause the
acceleration of) any performance or any increase in any payment required by, or
the termination, suspension, modification, impairment or forfeiture (or the
creation in any Person of any right to cause the termination, suspension,
modification, impairment or forfeiture) of any rights or privileges of Mobility
under its Certificate of Incorporation or Bylaws (each as amended to date), any
material agreement, instrument or undertaking (collectively, the "Material
Agreements") or any award, order, writ, decree, injunction or judgment of, or
any stipulation entered into in connection with any action or proceeding before,
any Governmental Authority (collectively, "Judgments") or regulatory or other
restriction or obligation to which Mobility or any of its Subsidiaries is a
party or by which Mobility, its Subsidiaries or their respective properties,
assets or business may be bound or affected, (b) will result (upon notice, with
the lapse of time or otherwise) in the creation, imposition or right to exercise
or foreclosure of a lien, charge, security interest, option, equity, claim or
other encumbrance of any nature whatsoever (collectively, "Liens") upon or in
any of the Securities or the Underlying Shares, or Lien upon any of the assets
or properties of Mobility or its Subsidiaries, (c) does or will conflict in any
respect with, or result in any violation of, any material ordinance, statute,
law, rule or regulation including, without limitation, the NASD Rules
(collectively "Laws") applicable to Mobility or its Subsidiaries or by which
Mobility, its Subsidiaries or their respective properties, assets or business
may be bound or affected, or (d) give rise to any rights of any holder of
Mobility capital stock or any other Person under that certain Rights Agreement
dated as of June 11, 2003, by and between Mobility and Computershare Trust

      4.5 Offering. Subject in part to the truth and accuracy of each Investor's
representations set forth in Section 4 hereof, the offer, sale and issuance of
the Securities as contemplated hereby are exempt from the registration
requirements of the Securities Act, and the qualification or registration
requirements of the applicable blue sky laws. Neither Mobility nor any
authorized agent acting on its behalf shall take any action hereafter that would
cause the loss of such exemptions.

      4.6 No Conflicting Rights. The holders of the outstanding capital stock of
Mobility are not entitled to pre-emptive or other rights to subscribe for the
Securities or the Underlying Shares.

      4.7 Legal Proceedings. Except as disclosed in SEC Reports, there is no
Legal Proceeding by or before any Governmental Authority or, to the knowledge of
Mobility, threatened in writing against or involving Mobility or its
Subsidiaries which either (a) is reasonably likely to result in material damages
to or any material injunctive relief against Mobility or its Subsidiaries or (b)
questions or challenges the validity of this Agreement, the Transactions or any
action taken or to be taken by Mobility or any of its Subsidiaries pursuant
hereto or in connection with the Transactions. Neither Mobility nor any of its
Subsidiaries is in, or has received written notice of, default under or in
violation of any Material Agreement, except as would not otherwise have a
Material Adverse Effect. Neither Mobility nor any of its Subsidiaries is subject
to any Judgment that materially restricts its business practices or its ability
to acquire any property or conduct its business as currently conducted.

      4.8 Government Authorizations and Filings. Except for filings, permits,
authorizations, consents, notices and approvals as may be required under, and
other applicable requirements of, the Exchange Act, state securities laws or
blue sky laws, none of the execution or delivery of this Agreement or the
Warrants, the performance by Mobility of the terms hereof or thereof, or the
consummation of the Transactions requires (a) any material filing with, or
material permit, authorization, consent or approval of, any Governmental
Authority, or (b) any consent or approval of Mobility's stockholders including,
without limitation, under the NASD Rules.

      4.9 Compliance with Laws. Mobility and each of its Subsidiaries are in
compliance in all material respects with, and have not violated in any material
respect any applicable law, rule or regulation of any United States federal,
state, local, or foreign Governmental Authority applicable to Mobility or any of
its Subsidiaries, except as would not otherwise have a Material Adverse Effect.
No written notice has been received by Mobility or any of its Subsidiaries or
has been filed, commenced or, to the knowledge of Mobility, threatened against
Mobility or any of its Subsidiaries alleging any such violation. All licenses,
permits and approvals required under such laws, rules and regulations are in
full force and effect except where the failure to be in full force and effect
would not reasonably be expected to result in a Material Adverse Effect.

                                       10
<PAGE>
      4.10 SEC Reports. Mobility has timely filed with the SEC the SEC Reports.
As of their respective dates (or, if amended or superseded, as of the date of
the last such amendment or superseding report filed prior to the date hereof),
the SEC Reports, including any financial statements or schedules included
therein (a) did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements made therein, in the light of the circumstances under which
they were made, not misleading and (b) complied in all material respects with
the applicable requirements of the Exchange Act and the Securities Act, as the
case may be, and the applicable rules and regulations of the SEC thereunder. The
Chief Executive Officer and the Chief Financial Officer of Mobility have signed,
and Mobility has furnished to the SEC, all certifications required by Section
906 of the Sarbanes-Oxley Act of 2002; such certifications contain no
qualifications or exceptions to the matters certified therein and have not been
modified or withdrawn; and neither Mobility nor any of it officers has received
notice from any Governmental Authority questioning or challenging the accuracy,
completeness, form or manner of filing or submission of such certifications.
None of Mobility's Subsidiaries is required to file any forms, reports or other
documents with the SEC.

      4.11 Financial Statements. Each of the Financial Statements has been
prepared from, and are in accordance with, the books and records of Mobility and
its Subsidiaries. The Financial Statements complied, as of their respective
dates, in all material respects with applicable accounting requirements and
published rules and regulations of the SEC. The Financial Statements have been
prepared in accordance with generally accepted accounting principles ("GAAP"),
applied on a consistent basis (except as may be indicated in the notes thereto
and subject, in the case of interim condensed consolidated financial statements,
to normal, recurring and year-end adjustments which were not and are not
expected to be material in amount and the absence of certain notes) and fairly
present in all material respects as of their respective dates (i) the
consolidated financial position of Mobility and its Subsidiaries as of the dates
thereof and (ii) the consolidated results of operations, changes in
stockholders' equity and cash flows of Mobility and its Subsidiaries for the
periods presented therein (except as may be indicated in the notes thereto and
subject, in the case of interim condensed consolidated financial statements, to
normal, recurring and year-end adjustments which were not and are not expected
to be material in amount and the absence of certain notes).

      4.12 No Undisclosed Liabilities. Except (a) as disclosed in the Financial
Statements, (b) for liabilities disclosed in SEC Reports, and (c) for
liabilities and obligations incurred in the ordinary course of business and
consistent with past practice since the Balance Sheet Date, neither Mobility nor
any of its Subsidiaries has any liability or obligation of any nature, whether
or not accrued, contingent or otherwise that would be required by GAAP to be
disclosed on a consolidated balance sheet of Mobility or in the notes thereto
and which, individually or in the aggregate, has had or is reasonably likely to
have a Material Adverse Effect. Mobility has not created any entities or entered
into any transactions or created any liabilities or obligations of any nature,
whether or not accrued, contingent or otherwise, for the purpose of avoiding
disclosure required by GAAP.

      4.13 Absence of Changes. Except as set forth on Schedule 4.13, since the
Balance Sheet Date, (a) no event or development has occurred which has had, or
could reasonably be expected to have, a Material Adverse Effect, and (b) the
business and operations of Mobility and each of its Subsidiaries have been
conducted in the ordinary course consistent with past practice.

      4.14 Finder's Fees. Except for the reasonable fees and expenses payable by
Mobility to Needham & Company, no agent, broker, investment banker, financial
advisor or other firm or Person is or shall be entitled to any brokers' or
finder's fee or any other commission or similar fee in connection with any of
the Transactions.

                                       11
<PAGE>
      4.15 Employee Benefit Plans. No Legal Proceeding is currently pending or,
to Mobility's knowledge, threatened in writing against or with respect to any
Mobility Benefit Plan (other than routine benefits claims) and there is no
pending audit or inquiry by the Internal Revenue Service or United States
Department of Labor with respect to any Mobility Benefit Plan. To the knowledge
of Mobility or any of its Subsidiaries, there exists no violations of any
Mobility Benefit Plan, nor has Mobility or any of its Subsidiaries received
written notice of any such violation, that could subject Mobility or any of its
Subsidiaries to any liability relating in any way to any Mobility Benefit Plan,
except as would not otherwise have a Material Adverse Effect.

      4.16 Tax Matters. Mobility and each of its Subsidiaries have duly filed
all Tax Returns that are required to be filed and for which taxes are due and
owing, and have duly paid, caused to be duly paid in full, or accrued for all
Taxes reflected on such Tax Returns. All such Tax Returns are correct and
complete in all material respects and accurately reflect all liability for Taxes
for the periods covered thereby. All material unpaid Taxes owed by Mobility and
all of its Subsidiaries relating to periods or portions of periods through the
Balance Sheet Date (whether or not shown on any Tax Return) are reflected on the
Financial Statements. Since the Balance Sheet Date, Mobility and its
Subsidiaries have not incurred any liability for any Taxes other than in the
ordinary course of business. Neither Mobility nor any of its Subsidiaries has
received written notice of any claim made by an authority in a jurisdiction
where Mobility or such Subsidiary, as the case may be, does not file Tax
Returns, that Mobility or such Subsidiary is or may be subject to taxation by
that jurisdiction.

      4.17 Title to Properties; Encumbrances. Except as set forth in Schedule
4.13, each of Mobility and each of its Subsidiaries has good, valid and
marketable title to all the material properties and assets which it purports to
own (real, personal and mixed, tangible and intangible) and which are reflected
in the Balance Sheet, and all the material properties and assets purchased by
Mobility and its Subsidiaries since the Balance Sheet Date, in each case free
and clear of all mortgages, title defects or objections, liens, claims, charges,
security interests or other encumbrances of any nature whatsoever including,
leases, chattel mortgages, conditional sales contracts, collateral security
arrangements and other title or interest retention arrangements, except, with
respect to all such properties and assets: (a) liens shown on the Balance Sheet
as securing specified liabilities or obligations, with respect to which no
default exists; (b) minor imperfections of title, if any, none of which are
substantial in amount, materially detract from the value or impair the use of
the property subject thereto, or impair the operations of Mobility or any of its
Subsidiaries and which have arisen only in the ordinary course of business and
consistent with past practice since the date of the Balance Sheet; and (c) liens
for current Taxes not yet due (collectively, "Permitted Liens"). Except as set
forth in Schedule 4.13, the rights, properties and other assets presently owned,
leased or licensed by Mobility and its Subsidiaries include all rights,
properties and other assets necessary to permit Mobility and its Subsidiaries to
conduct their businesses in all material respects in the same manner as their
businesses have been conducted prior to the date hereof.

      4.18 Intellectual Property.

            (a) Ownership; Sufficiency of IP Assets. Except as set forth in
      Schedule 4.18, Mobility or one of its Subsidiaries owns or possesses
      adequate licenses or other rights to use, free and clear of liens (other
      than Permitted Liens), all of the Intellectual Property used in, and
      material to, its respective businesses. The Mobility Intellectual
      Property, together with rights under the licenses granted to Mobility
      and/or its Subsidiaries with respect to any Intellectual Property of any
      Person (other than Mobility or its Subsidiaries), constitutes all the
      Intellectual Property rights used in the operation of Mobility's and its
      Subsidiaries' businesses as they are currently conducted and are all the
      Intellectual Property rights necessary to operate such businesses after
      the Closing in substantially the same manner as such businesses have been
      operated by Mobility and its Subsidiaries prior thereto; provided,
      however, that the foregoing representation, as it relates

                                       12
<PAGE>
      solely to Intellectual Property rights with respect to patents owned by
      any Person (other than Mobility and its Subsidiaries), is made only to the
      knowledge of Mobility.

            (b) Infringement.

                  (i) By Mobility. None of Mobility's products or Intellectual
      Property used, sold or manufactured by Mobility or its Subsidiaries in the
      conduct of Mobility's or its Subsidiaries' businesses as currently
      conducted, infringes upon, violates or constitutes the unauthorized use of
      any trade secret, copyright or mask work owned or controlled by any Person
      (other than Mobility or its Subsidiaries), and to the knowledge of
      Mobility, none of Mobility's products or Intellectual Property used, sold,
      or manufactured by Mobility or its Subsidiaries in the conduct of
      Mobility's or its Subsidiaries' businesses as currently conducted,
      infringes upon any patent rights or other intellectual property rights
      owned or controlled by any Person (other than Mobility or its
      Subsidiaries). Except as disclosed in the SEC Reports and as set forth on
      Schedule 4.18(b)(i) hereto, no Legal Proceeding to which Mobility is a
      party is now pending and, to the knowledge of Mobility, no notice or claim
      in writing has been received by Mobility or any of its Subsidiaries within
      the six (6) years prior to the date hereof (A) alleging that Mobility or
      any of its Subsidiaries has engaged in any activity or conduct that
      infringes upon, violates or constitutes the unauthorized use of the
      Intellectual Property rights of any Person (other than Mobility or its
      subsidiaries) or (B) challenging the ownership, use, validity or
      enforceability of any Intellectual Property owned by or exclusively
      licensed to or by Mobility.

                  (ii) By Third Parties. Except as set forth on Schedule
      4.18(b)(ii) hereto, no Person is misappropriating, infringing or violating
      any Mobility Intellectual Property (other than Mobility patents) other
      than instances that, either individually or in the aggregate, would not
      result in a Material Adverse Effect, and, to the knowledge of Mobility, no
      Person is infringing or violating any Mobility patents. Except as set
      forth on Schedule 4.18(ii) hereto, no claims have been asserted against
      any Person by Mobility or any of its Subsidiaries based upon any Mobility
      Intellectual Property.

      4.19 Employment Matters. Mobility and each of its Subsidiaries are in
compliance in all material respects with all currently applicable laws and
regulations respecting employment, discrimination in employment, terms and
conditions of employment, wages, hours and occupational safety and health and
employment practices, and is not engaged in any unfair labor practice except as
would not otherwise have a Material Adverse Effect. There is no controversy
pending or, to the knowledge of Mobility, threatened, between Mobility or any of
its Subsidiaries, on the one hand, and any of their respective employees, on the
other hand, which controversies have resulted, or could reasonably be expected
to result, in a Legal Proceeding before any Governmental Authority in which an
adverse decision would result in a Material Adverse Effect except as disclosed
in the SEC Reports. To the knowledge of Mobility, no officer or key employee of
Mobility is in violation of any material term of any employment contract, patent
disclosure agreement, noncompetition agreement, or any restrictive covenant to a
former employer relating to the right of any such employee to be employed by
Mobility or a Subsidiary of Mobility because of the nature of the business
conducted by Mobility or any of its Subsidiaries or to the use of trade secrets
or proprietary information of others.

      4.20 Certain Corporate Matters.

            (a) No state takeover, antitakeover, moratorium, fair price,
      interested stockholder, business combination or similar statute or rule is
      applicable to the Transactions. If any state takeover statute becomes or
      is deemed to become applicable to this Agreement or the

                                       13
<PAGE>
      Transactions, Mobility shall (and shall cause each of its applicable
      Subsidiaries to) take all reasonable action necessary to render such
      statute inapplicable to all of the foregoing.

            (b) None of Mobility, its Subsidiaries or, to Mobility's knowledge,
      any director, officer, agent, employee or other Person acting on behalf of
      Mobility or any of its Subsidiaries, has used any corporate or other funds
      for any unlawful contribution, payment, gift, or entertainment, or made
      any unlawful expenditure relating to political activity to government
      officials or others or established or maintained any unlawful or
      unrecorded funds in violation of Section 30A of the Exchange Act. None of
      Mobility, its Subsidiaries or, to Mobility's knowledge, any current
      director, officer, agent, employee or other Person acting on behalf of
      Mobility or any of its Subsidiaries, has accepted or received any unlawful
      contribution, payment, gift or expenditure. Mobility and each of its
      Subsidiaries which is required to file reports pursuant to Section 12 or
      15(d) of the Exchange Act is in compliance in all material respects with
      the provisions of Section 13(b) of the Exchange Act.

            (c) Except as disclosed in SEC Reports, to Mobility's knowledge, no
      executive officer or director of Mobility or any of its Subsidiaries has
      any material interest in any material property, real or personal, tangible
      or intangible, including any Intellectual Property used in or pertaining
      to the business of Mobility or any of its Subsidiaries.

      4.21 Disclosure. To the knowledge of Mobility, neither the Agreement nor
the Warrants (including all exhibits and schedules hereto or thereto) nor any
other statements or certificates made or delivered in writing in connection
herewith contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements herein or therein not misleading
in light of the circumstances under which they were made.

Expenses shall be determined in accordance with generally accepted accounting
principles, consistently applied ("GAAP"); (ii) 50% of the IP Expenses shall be
allocated to the Division, and (iii) a reasonable portion of the quarterly
Indirect Expenses shall be allocated to the Division; provided, however, that

and general and administrative expenses, Indirect Expenses and IP Expenses of
the Division (excluding the iTip Products Commission (and any similar commission

shall not exceed (1) if the Permitted Sales Revenues of the Division for any

Revenue of the Division for any calendar year is at least $50 million but less

Sales Revenue of the Division for such calendar year, or (B) the percentage
equal to Mobility's overall sales, marketing, research and development, and
general and administrative expenses as compared to its overall revenues (net of
returns and allowances) for such calendar year (for each calendar year, the
"Maximum Overall Operating Expense Percentage"); (3) if the Permitted Sales
Revenue of the Division for any calendar year is $100 million or more, the
lesser of (A) twenty percent (20%) of the Permitted Sales Revenue of the
Division for such calendar year, or (B) the Maximum Overall Operating Expense
Percentage for such calendar year. The limitations set forth in (1), (2) and (3)
of the previous sentence being collectively referred to as the "Maximum

            voltage, current and/or power requirements for the purpose of
            operating or charging the battery for an electronic device (e.g.,
            cell phones, PDA's, digital cameras, MP3 players, CD players, and

            (b) Sales Channels and Territory. Sales Rep shall have the worldwide
right to act as Mobility's sales representative for the sale of Mobility
Products; provided, however, that in the event of any channel conflict issues
affecting Sales Rep, Mobility shall consult with Sales Rep regarding such issues

Parties

                                       2
<PAGE>

and third parties involved in the channel conflict issue (including, without
limitation, consideration of Sales Rep's pre-existing relationships with carrier
customers). In the event that Sales Rep does not accept Mobility's resolution of
the channel conflict issue, Sales Rep can appeal such decision to the Chief

make the final determination of such channel conflict issue. If following such
final determination Sales Rep still does not accept such resolution, Sales Rep

            (c) Sales Policies. All sales activities conducted by Sales Rep
pertaining to the Mobility Products will be in accordance with the sales

Chief Operating Officer of Mobility, who shall make the final determination of
such sales policy change. If following such final determination Sales Rep still
does not accept such sales policy change, Sales Rep may terminate this Agreement
without liability upon written notice to Mobility, in which event, this
Agreement shall be null and void and of no further force or effect. All orders
for the Mobility Products shall be solicited at prices specified by Mobility.
Sales Rep acknowledges specifically that all sales solicitations are to be made
on the basis of Mobility's sales policy as provided in Exhibit D, as may be
changed as provided above.

            (d) Sales Orders. All sales orders and agreements relating to the
purchase of Mobility Products shall be subject to approval by Mobility, and all
contracts and purchase orders shall be executed and placed with Mobility.
Mobility's approval of a sales order or agreement relating to the purchase of
Mobility Products shall be based primarily on Sales Rep's compliance with
Mobility's sales policies. Sales Rep shall promptly notify Mobility with respect
to any and all customers who are interested in purchasing Mobility Products, and
any and all potential customer issues. If Sales Rep desires pre-approval by
Mobility of a sales order for a particular potential customer, Mobility shall,
upon the request of Sales Rep, provide Sales Rep certain terms and conditions
for such pre-approval (e.g., quantity, price, payment terms and delivery
schedule). Notwithstanding anything to the contrary contained in this Agreement,
no order for Mobility Products shall be binding unless accepted in writing by an
authorized representative of Mobility (except that any pre-approved conditions
quoted by Mobility to Sales Rep for a particular potential customer for a
specified order shall be binding upon Mobility for that particular customer
pertaining to such specified order).

            (e) Collection Activities. Mobility shall be responsible for the
collection of all accounts receivable relating to the sale of Mobility Products,
but Sales Rep agrees to provide reasonable assistance to Mobility in this area
for customers of Mobility managed by Sales Rep

<PAGE>

(e.g., making phone calls, requesting payment and/or other communications with
the customer) as reasonably requested by Mobility from time to time.

            (f) Rolling Forecast. Mobility and Sales Rep will work together to
formulate, on a monthly basis, a detailed, non-binding, rolling 12-month
forecast for: (i) Sales Rep's sales of Mobility Products (broken-down by
product, customer and geography) on behalf of Mobility; and (ii) Mobility's
manufacturing and delivery schedule and backlog, with the first forecast being
completed on or prior to April 30, 2005.

            (g) Customer Support and Other Product Issues. Except as otherwise
specified herein, Mobility shall be responsible for all Mobility Product related
issues (and expenses), including, without limitation, technical support and
warranty issues. Furthermore, Sales Rep will not hold any inventory under this
Agreement nor will Sales Rep be responsible for any costs of distribution
programs established by Mobility. Notwithstanding the above, all of the costs
and expenses described above in this subsection (g) shall be considered costs
and expenses of the Division and shall be paid for by the Division.

            (h) Representations and Warranties. Mobility represents and warrants
that it is under no obligation or restriction, and it will not assume or incur
any such obligation or restriction, that does or would in any material way
interfere or conflict with the performance of this Agreement by Mobility.
Mobility represents and warrants that (i) it has and will have full and
sufficient title and/or right and interest to the Mobility Products and
underlying technology to grant the rights to Sales Rep that are granted pursuant
to this Agreement; and (ii) neither the execution or performance by Mobility of
this Agreement, nor the consummation of any transactions contemplated herein
does or will (a) violate any law, order, regulation or ruling applicable to
Mobility, or (b) infringe any intellectual or other property, personal or
contract rights of any third party. To the extent permitted under Regulation FD,
Mobility agrees to promptly inform Sales Rep upon the occurrence of: (i)
Mobility's receipt of any third party intellectual property infringement claims
and any third party material lawsuits, in either case, which affects the
Division or the iTip Technology; (ii) any change to the composition of
Mobility's senior management team; and (iii) any decision by Mobility to undergo
a Change in Control (as defined in Section 8(b)) or to enter into a joint
venture, partnership or acquire all or substantially all of the assets of a
third party, in any case. which affects the Division or the iTip Technology.

            (i) Most Favored Sales Representative. Mobility represents and
warrants that it will not enter into any sales representative agreement related
to iTip Products which provides for a "profits participation" type of sharing
arrangement similar to that of Section 3(a) below on terms and conditions more
favorable than those set forth in this Agreement.

      3. COMMISSIONS.

            (a) Commissions for iTip Products. Mobility will pay Sales Rep a
commission, payable on a calendar quarterly basis, equal to twenty-four and one
half percent (24.5%) of the "Pre-Commission EBIT" earned by the Division during
each calendar quarter (collectively, the "iTip Products Commission"); provided,
however, if Pre-Commission EBIT for any period is a negative number (i.e., a
loss for such period) (an "EBIT Loss"), then the EBIT

                                       4
<PAGE>

Loss shall be allocated entirely to Mobility, and for any subsequent period(s)
in which there is a positive pre-Commission EBIT, Mobility shall be allocated
all of such Pre-Commission EBIT until Mobility recovers all EBIT Loss previously
allocated to Mobility. For purposes of calculating the Commission, the following
terms shall have the following meanings:

                  (i) "Pre-Commission EBIT" means Permitted Sales Revenues of
            the Division for iTip Products less: (1) returns and allowances for
            iTip Products; (2) cost of goods sold of the Division for iTip
            Products (excluding cost of goods sold for products where the
            revenue is excluded from the definition of Permitted Sales Revenue
            (as provided in such definition)); (3) the Direct Expenses of the
            Division; (4) the IP Expenses; and (5) the Indirect Expenses of the
            Division.

                  (ii) "Permitted Sales Revenues" means all revenues (including
            without limitation, licensing revenues and sales revenues) of the
            Division for iTip Products and/or iTip Technology, excluding: (1)
            the Computer Portion of the sales revenues attributable to any
            product that is an iTip Product, but is bundled with any one or more
            Computer Products; and (2) revenues generated from the sale of the
            products through the RadioShack Channel during the transition period
            as provided for in Exhibit E attached hereto. As used above, (i)
            "Computer Portion" shall mean that portion of sales revenue for the
            bundled product multiplied by a fraction, the numerator of which
            shall be the manufactured suggested retail price of the Computer
            Product contained in such bundled product, and the denominator of
            which shall be the manufactured suggested retail price of the iTip
            Product portion of the bundled product plus the manufactured
            suggested retail price of the Computer Product contained in such
            bundled product (provided, however, that the portion remaining after
            excluding the Computer Portion must be greater than the
            manufacturing cost of the iTip Product portion of the bundled
            product); and (ii) "RadioShack Channels" shall mean RadioShack
            Corporation's retail stores (including its dealer/franchise stores,
            but excluding its Sam's Club program, and its Sprint kiosk program)
            in the United States and its territories and Mexico, and
            RadioShack.com.

            (b) Commissions for Computer Products. Mobility will pay Sales Rep a
commission, payable on a calendar quarterly basis, equal to three percent (3.0%)
of the sales price (net of returns and allowances) for any Computer Product sold
by Sales Rep under this Agreement during each calendar quarter; provided,
however, for any Computer Product bundled with any iTip Product, such commission
shall be reduced by the three percent (3.0%) of the iTip Portion (the "Computer
Products Commission", and collectively with the iTip Products Commission, the
"Commissions"). As used above, "iTip Portion" shall mean that portion of sales
revenue for the bundled product multiplied by a fraction, the numerator of which
shall be the manufactured suggested retail price of the iTip Product contained
in such bundled product, and the denominator of which shall be the manufactured
suggested retail price of the iTip Product portion of the bundled product plus
the manufactured suggested retail price of the Computer Product contained in
such bundled product.

            (c) Payments. Within twenty (20) days after the end of each calendar
quarter, Mobility shall provide a report to Sales Rep setting forth the
Commission due to Sales Rep for

                                       5
<PAGE>

such calendar quarter (the "Commission Report"), and shall pay such Commissions
concurrent with the delivery of the Commission Report.

            (d) Audit Rights. Mobility agrees to make and maintain such books,
records and accounts as are reasonably necessary to verify the accuracy of the
Commissions payments made to Sales Rep. Mobility agrees that it will, at the
sole expense of Sales Rep, permit Sales Rep's auditors to have reasonable access
to Mobility's business records and books of account, upon at least five (5)
business days' prior notice and no more than once during each fiscal year,
during Mobility's normal business hours for the purpose of determining whether
the appropriate Commissions have been made to Sales Rep for the prior 12-month
period. If any such audit discloses that Mobility has underpaid Sales Rep,
Mobility agrees to pay any shortfall within thirty (30) days; provided, however,
if Mobility disagrees with any underpayment, Mobility will direct its auditors
to engage in discussions with Sales Rep's auditors in order to reach a mutually
agreeable resolution of the issue. If any such audit discloses an underpayment
of over five percent (5%) of amounts otherwise owed to Sales Rep, Mobility shall
reimburse Sales Rep for the reasonable costs of the audit. If any audit
discloses any overpayment to Sales Rep by Mobility, Sales Rep shall refund the
amount of such overpayment within thirty (30) days. Notwithstanding anything to
the contrary contained in this subsection (d), if during a calendar year the
Total Operating Expenses (expressed as a percentage of the Permitted Sales
Revenue of the Division) do not exceed the Maximum Overall Operating Expense
Percentage for such calendar year, then in no event may Sales Rep audit or
question any determination by Mobility to incur a particular cost or expense or
take a particular action (e.g., hire personnel, purchase equipment, develop a
product, sue for intellectual property infringement, etc); although Sales Rep
may audit whether the allocation was proper.

            (e) Commissions Adjustments. Returns, allowances, other deductions
from the sale price, or any other adjustments to the Commissions calculations
shall be debited or credited, as appropriate, during the calendar quarter in
which they arise.

      4. EXPENSES. Mobility shall have no liability for any expenses that may be
incurred by Sales Rep to carry out its obligations under this Agreement. Sales
Rep agrees that it shall incur no expense chargeable to Mobility except as may
be specifically authorized in advance and in writing by an authorized officer of
Mobility.

      5. MARKETING MATERIALS. Mobility will provide, without cost to Sales Rep,
reasonable supplies of standard advertising literature and samples which
Mobility deems to be required to encourage and facilitate the sale of the
Mobility Products. In the event that a customer or potential customer desires or
requires specialized marketing materials and/or advertising allowances in order
to undertake a marketing or advertising program involving Mobility Products,
Mobility and Sales Rep shall work together to determine the extent of Mobility's
financial commitment thereto, if any; it being the intent of the Parties that
Mobility will incur such types of expenses in situations where it is
economically justified or "standard practice" (e.g., carrier co-op programs).
Such commitments by Mobility will be deemed Direct Expenses of the Division.

      6. NON-COMPETITION AND RESTRICTED ACTIVITIES.

                                       6

Mobility shall be that of special representative for purposes of sales
solicitation. Sales Rep shall not be considered the agent or legal
representative of Mobility for any purpose, except as provided herein, and no
officer, agent or employee of Sales Rep shall be considered as having employee
status with Mobility. Sales Rep shall remain, for all purposes, an independent
contractor and nothing in this Agreement shall constitute Sales Rep as an agent,
representative, subsidiary, joint venture, partner, employee, or servant of
Mobility for any purpose whatsoever. Sales Rep is not granted the right of
authority to assume, or to create any obligation or responsibility, express or
implied, on behalf of, or in the name of, Mobility, except as may be provided
herein, or as may specifically be authorized in writing by an authorized
official of Mobility.

      8. TERM AND TERMINATION.

            (a) Initial Term. This Agreement shall be effective as of the
Effective Date and shall remain in effect for fifteen (15) years following the
Effective Date (the "Initial Term"). Thereafter, this Agreement shall

Party at least one hundred and twenty (120) days prior to the end of the Initial
Term or any Renewal Term. The Initial Term and any Renewal Term(s) are

survive such expiration or termination, unless Sales Rep provides a written
notice to Mobility at the time of such expiration or termination that Sales Rep
elects to terminate the provisions of Sections 3(a), (c), (d) and (e) above, in
which event all terms and provisions of this Agreement shall terminate and be of
no further force or effect.

            (b) Termination. In addition to the other termination rights set
forth in this Agreement, a Party will only have the right to terminate this

willful behavior of the Indemnifying Party), together with lawful interest
thereon. The term "Damages" shall not include any amounts for which any
Indemnified Party actually receives payment under an insurance policy, excluding
