                           MOBILITY ELECTRONICS, INC.

             SERIES E PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT


         This Series E Preferred Stock and Warrant Purchase Agreement (the
"Agreement") is made as of January 14, 2003, by and between Mobility
Electronics, Inc., a Delaware corporation (the "Company"), and Dolphin Offshore
Partners, L.P. (the "Investor").

         The parties hereby agree as follows:

         1. PURCHASE AND SALE OF PREFERRED STOCK AND WARRANT.

                  1.1 SALE AND ISSUANCE OF SERIES E PREFERRED STOCK AND WARRANT.

                           (a) The Company is undertaking a private placement
(the "Offering") to "accredited investors" (as such term is defined in Section
501(a) of Regulation D promulgated under the Securities Act of 1933, as amended
(the "Act")) ("Accredited Investor") of up to 865,051 shares of Series E
Preferred Stock, par value $0.01 per share (the "Series E Stock") at a purchase
price of $0.7225 per share (the "Issuance Price") and up to 729,407 shares of
Series F Preferred Stock, par value $0.01 per share (the "Series F Stock") at a
purchase price of $0.85 per share. For each share of Series E Stock purchased by
an Accredited Investor in the Offering, such Accredited Investor will be issued,
for no additional cost, a warrant to purchase twenty-five percent (25%) of a
share of common stock, par value $0.01 per share, of the Company ("Common
Stock"), at an exercise price of $0.867 per share (the "Warrant Exercise
Price"). For each share of Series F Stock purchased by an Accredited Investor in
the Offering, such Accredited Investor will be issued, for no additional cost, a
warrant to purchase forty-seven percent (47%) of a share of common stock, par
value $0.01 per share, of the Company ("Common Stock"), at an exercise price of
$1.02 per share. The Series F Stock portion of the Offering has been developed
in order to permit the Company's officers and directors, and their affiliates,
to participate in the Offering without obtaining stockholder approval pursuant
to NASD Rule 4350, and will be offered only to the Company's officers and
directors, and their affiliates. The Offering may be closed at one or more
closings.

                           (b) The Company has adopted and filed with the
Secretary of State of the State of Delaware a Certificate of the Designations,
Preferences, Rights and Limitations of Series E Preferred Stock of the Company,
a copy of which is attached hereto as Exhibit A (the "Certificate of
Designations").

                           (c) The Company has adopted and filed with the
Secretary of State of the State of Delaware a Certificate of the Designations,
Preferences, Rights and Limitations of Series F Preferred Stock of the Company,
a copy of which is attached hereto as Exhibit A-2 (the "Series F Designations").

                           (d) Subject to the terms and conditions of this
Agreement, Investor agrees to purchase at the Closing (as defined below) and the
Company agrees to sell and issue to Purchaser at the Closing 865,051 shares of
Series E Stock at the Issuance Price per share, for an



                                       1
<PAGE>



aggregate purchase price of $624,999.35. The shares of Series E Stock issued to
Purchaser pursuant to this Agreement shall be hereinafter referred to as the
"Stock".

                           (e) Subject to the terms and conditions of this
Agreement, at the Closing the Company agrees to issue to Purchaser, at no
additional cost, a warrant to purchase up to 216,263 shares of Common Stock, at
the Warrant Exercise Price per share, which warrant shall be in the form of
Exhibit B attached hereto (the "Warrant"). The Stock and Warrant are sometimes
collectively referred to herein as the "Securities".

                           (f) Notwithstanding any provision in this Agreement
or the Certificate of Designations to the contrary, Purchaser (i) expressly
acknowledges that the issuance consideration for the Series E Stock and Series F
Stock are different, (ii) expressly acknowledges that a purchaser of a share of
Series F Stock will receive warrants to purchase more shares of Common Stock
than a purchaser of a share of Series E Stock, and (iii) consents to the
authorization and issuance by the Company of the Series F Stock in the Offering
and any future issuance of Series F Stock as payment of any dividends required
to be paid to holders of Series F Stock under the Series F Designations.

                           (g) The Company hereby grants to Investor, with
respect to the shares of Common Stock underlying the Stock and the Warrants,
registration rights as set forth in Exhibit C; it being specifically agreed and
understood that the shares of Common Stock underlying the Stock and Warrant will
be included in any registration statement filed by the Company which includes
shares of Common Stock underlying other shares of Series E Stock, Series F Stock
and Common Stock Purchase Warrants sold to Accredited Investors in the Offering.

                  1.2 CLOSING; DELIVERY.

                           (a) The purchase and sale of the Stock shall take
place at the offices of the Company, 17800 N. Perimeter Drive, Suite 200,
Scottsdale, Arizona 85255, at 10:00 a.m. (Scottsdale time), on the date hereof,

or in writing (which time and place are designated as the "Closing").

                           (b) At the Closing, the Company shall deliver to
Investor: (i) a certificate representing the Stock being purchased hereby; and

performance of this Agreement or the Warrant nor the consummation of the
transactions contemplated hereby or thereby will (a) conflict with, or result in

enter into this Agreement. This Agreement constitutes the valid and legally
binding obligation of Investor, enforceable in accordance with its terms, except

Securities to be acquired by Investor will be acquired for investment for
Investor's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that Investor has no present
intention of selling, granting any participation in, or otherwise distributing
the same. By executing this Agreement, Investor further represents that Investor

                  3.4 RESTRICTED SECURITIES. Investor understands that the

requirements is available. Investor acknowledges that the Company has no
obligation to register or qualify the Securities for resale except as set forth
in Exhibit C. Investor further acknowledges that if an exemption from
registration or qualification is available, it may be conditioned on various
requirements including, but not limited to, the time and manner of sale, the
holding period for the Securities, and on requirements relating to the Company
which are outside of Investor's control, and which the Company is under no
obligation and may not be able to satisfy.

2. Registration.

         (a) Filing and Effectiveness of Registration Statement. The Company

the initial closing (the "Initial Closing") of sales of Offered Shares and
Warrants under the Offering (the "Filing Deadline") a Registration Statement
relating to the offer and sale of the Registrable Securities by the Investors



                                       2
<PAGE>



and shall use all commercially reasonable efforts to cause the Commission to
declare such Registration Statement effective under the Securities Act as
promptly as practicable, but not later than 120 days after the Initial Closing.
All of the shares of Common Stock sold in the Offering shall be included in such
Registration Statement; provided, however, that the Company shall not be
required to include in the Registration Statement Registrable Securities of any
Investor who has failed to provide the Company with the information pertaining
to such Investor that is required to be included in such Registration Statement
pursuant to Item 507 and/or Item 508 of Regulation S-K. The Company shall notify
the Investors in writing by telecopy or e-mail notice that such Registration
Statement has been declared effective by the Commission on the date of such
declaration by the Commission. The Company agrees to keep such Registration
Statement effective until the earlier of: (i) the passage of two years from the
effective date of such Registration Statement; or (ii) the date on which all
Registrable Securities may be resold by all Investors by reason of Rule 144(k)
under the Securities Act or any other rule of similar effect.

         (b) Piggyback Registration Rights. (i) Without limiting the obligations
of the Company pursuant to Section 2(a) above, until such date as the
Registration Statement to be filed in accordance with Section 2(a) is declared
effective by the Commission, if the Company proposes to register any of its
Common Stock or any other shares of common stock of the Company under the
Securities Act (other than a registration (A) on Form S-8 or S-4 or any
successor or similar forms, (B) relating to Common Stock or any other shares of
common stock of the Company issuable upon exercise of employee or consultant
share options or in connection with any employee benefit or similar plan of the
Company or (C) in connection with a direct or indirect acquisition by the
Company of another Person or any transaction with respect to which Rule 145 (or
any successor provision) under the Securities Act applies), whether or not for
sale for its own account, it will each such time, give prompt written notice at
least 20 days prior to the anticipated filing date of the registration statement
relating to such registration to the Investors, which notice shall set forth
such Investors' rights under this Section 2(c) and shall offer the Investors the
opportunity to include in such registration statement such number of Registrable
Securities as the Investors may request. Upon the written request of an Investor
made within 10 days after the receipt of notice from the Company (which request
shall specify the number of Registrable Securities intended to be disposed of by
such Investors), the Company will use all reasonable commercial efforts to
effect the registration under the Securities Act of all Registrable Securities
that the Company has been so requested to register by the Investors, to the
extent requisite to permit the disposition of the Registrable Securities to be
so registered; provided, however, that (A) if such registration involves a
Public Offering, the Investors must sell their Registrable Securities to the
underwriters on the same terms and conditions as apply to the Company and (B)
if, at any time after giving written notice of its intention to register any
Common Stock pursuant to this Section 2(b) and prior to the effective date of
the registration statement filed in connection with such registration, the
Company shall determine for any reason not to register such Common Stock, the
Company shall give written notice to the Investors and, thereupon, shall be
relieved of its obligation to register any Registrable Securities in connection
with such registration. The Company's obligations under this Section 2(b) shall
terminate on the date that the Registration Statement to be filed in accordance
with Section 2(a) is declared effective by the Commission. (ii) If a
registration pursuant to this Section 2(b) involves a Public Offering and the
managing underwriter thereof advises the Company that, in its view, the number
of shares of Common Stock, if any, or other shares of Common Stock that the
Company and the Investors intend to include in such registration exceeds the
largest number of shares of



                                       3
<PAGE>



Common Stock (including any other shares of Common Stock or warrants of the
Company) that can be sold without having a material adverse effect on such
Public Offering (the "Maximum Offering Size"), the Company will include in such
registration only that number of shares of Common Stock which does not exceed
the Maximum Offering Size, in the following order of priorities: (1) first, all
securities the Company proposes to sell for its own account, (2) second, up to
the full number of securities proposed to be registered for the account of the
holders of securities entitled to inclusion of their securities in the
Registration Statement by reason of demand registration rights, and (3) third,
the securities requested to be registered by other holders of securities
entitled to participate in the registration, drawn from them pro-rata based on
the number of shares each has requested to be included in such registration and
the Investors pursuant to this Exhibit C. If as a result of the proration
provisions of this Section 2(b), the Investors are not entitled to include all
such Registrable Securities in such registration, such Investors may elect to
withdraw their request to include any Registrable Securities in such
registration.

         Notwithstanding the foregoing, the Company shall have no obligations
under this Section 2(b) hereof at any time that such Registrable Securities are
the subject of an effective registration statement.

3. Obligations of the Company. In connection with the registration of the
Registrable Securities, the Company shall use all commercially reasonable
efforts to:

         (a) Subject to the provisions of Section 3(q) hereof, promptly (i)
prepare and file with the Commission such amendments (including post-effective
amendments) to the Registration Statement and supplements to the Prospectus as
may be necessary to keep the Registration Statement continuously effective and
in compliance with the provisions of the Securities Act applicable thereto so as
to permit the Prospectus forming part thereof to be current and useable by
Investors for resales of the Registrable Securities for a period of two years
from the date the Registration Statement is first declared effective by the
Commission (the "Effective Time") or such shorter period that will terminate
when all the Registrable Securities covered by the Registration Statement have
been sold pursuant thereto in accordance with the plan of distribution provided
in the Prospectus or otherwise cease to be Registrable Securities (the
"Registration Period") 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, 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. Notwithstanding the foregoing, the Company's obligations
hereunder shall terminate as to any investor at such time as that Investor's
Registrable Securities can be sold under Rule 144(k);

         (b) During the Registration Period, comply with the provisions of the
Securities Act with respect to the Registrable Securities of the Company covered
by the Registration Statement until such time as all of such Registrable
Securities have been disposed of in accordance with the



                                       4

intended methods of disposition by the Investors as set forth in the Prospectus

are included in the Registration Statement, (A) promptly after the same is
prepared and publicly distributed, filed with the Commission, or received by the
Company, one copy of the Registration Statement, each Prospectus, and each
amendment or supplement thereto, and (B) such number of copies of the Prospectus
and all amendments and supplements thereto and such other documents, as such
Investor may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such Investor;

         (d) (i) Register or qualify the Registrable Securities covered by the
Registration Statement under such securities or "blue sky" laws of all
jurisdictions requiring blue sky registration or qualification, (ii) prepare and

and supplements to such registrations and qualifications as may be reasonably
necessary to maintain the effectiveness thereof at all times during the
Registration Period, (iii) take all such other lawful actions as may be
reasonably necessary to maintain such registrations and qualifications in effect
at all times during the Registration Period, and (iv) take all such other lawful
actions reasonably necessary or advisable to qualify the Registrable Securities
for sale in such jurisdictions; provided, however, that the Company shall not be
required in connection with any of its obligations under this Section 3(d) to
(A) qualify to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d), (B) subject itself to general
taxation in any such jurisdiction or (C) file a general consent to service of
process in any such jurisdiction;

         (e) As promptly as practicable after becoming aware of such event,

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
promptly prepare an amendment to the Registration Statement and supplement to
the Prospectus to correct such untrue statement or omission, and deliver a
number of copies of such supplement and amendment to each Investor as such
Investor may reasonably request;

         (f) Notify each Investor who holds Registrable Securities being sold
(or, in the event of an underwritten offering, the managing underwriters) of the

effectiveness of the Registration Statement on the date of receipt of any such
stop order or other suspension, and take all lawful action to effect the
withdrawal, recession or removal of such stop order or other suspension;

Securities are included in such registration statement) an appropriate
instruction and, to the extent necessary, an opinion of such counsel;

         (j) Take all such other lawful actions reasonably necessary to expedite

         (l) In the event of an underwritten offering, promptly include or

under which they were made) not misleading, subject to customary limitations);

         (o) In connection with any underwritten offering, obtain "cold comfort"

<PAGE>



Registrable Securities and shall execute such documents in connection with such

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, in
light of the circumstances under which they were made, not misleading; and

         (d) Each Investor agrees that, upon receipt of any notice from the

         (a) The Company shall indemnify and hold harmless each Investor and
each underwriter, if any, which facilitates the disposition of Registrable
Securities, and each of their respective officers and directors, trustees,
employees, advisors, legal counsel and accountants and each person who controls
such Investor or underwriter within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act (each such person being sometimes
hereinafter referred to as an "Indemnified Person") from and against any losses,
claims, damages or liabilities, joint or several, to which such Indemnified
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 an untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement or an omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, not misleading, or arise out of or are
based upon an untrue statement or alleged untrue statement of a material fact
contained in any Prospectus or an omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were

<PAGE>



Company hereby agrees to reimburse such Indemnified Person for all reasonable
legal and other expenses incurred by them in connection with investigating or
defending any such action or claim as and when such expenses are incurred;
provided, however, that the Company shall not be liable to any such Indemnified
Person in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon (i) an untrue statement or alleged
untrue statement made in, or an omission or alleged omission from, such
Registration Statement or Prospectus in reliance upon and in conformity with
written information furnished to the Company by such Indemnified Person
expressly for use therein or (ii) in the case of the occurrence of an event of
the type specified in Section 3(e), the use by the Indemnified Person of an
outdated or defective Prospectus after the Company has provided to such
Indemnified Person written notice that such Prospectus is outdated or defective.

         (b) Indemnification by the Investors and Underwriters. Each Investor
agrees, as a consequence of the inclusion of any of its Registrable Securities
in a Registration Statement, and each underwriter, if any, which facilitates the
disposition of Registrable Securities shall agree, as a consequence of
facilitating such disposition of Registrable Securities, severally and not
jointly, to (i) indemnify and hold harmless the Company, its directors
(including any person who, with his or her consent, is named in the Registration
Statement as a director nominee of the Company), its officers, employees,
advisors, legal counsel and accountants and each person, if any, who controls
the Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any losses, claims, damages or
liabilities to which the Company or such other persons 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: (y)
an untrue statement or alleged untrue statement of a material fact contained in
such Registration Statement or Prospectus 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 (in light of the
circumstances under which they were made, in the case of the Prospectus), not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information furnished to the
Company by such Investor or underwriter expressly for use therein; or (z) in the
case of the occurrence of an event of the type specified in Section 3(e) above,
the use by the Indemnified Person of an outdated or defective Prospectus after
the Indemnified Person has received from the Company written notice that such
Prospectus is outdated or defective; provided, however, that no Investor or
underwriter shall be liable under this Section 6(b) for any amount in excess of
the net proceeds paid to such Investor or underwriter in respect of shares sold
by it; and (ii) reimburse the Company for any reasonable legal or other expenses
incurred by the Company in connection with investigating or defending any such
action or claim as such expenses are incurred.

         (c) Notice of Claims, Etc. Promptly after receipt by a party seeking
indemnification pursuant to this Section 6 (an "Indemnified Party") of written
notice of any investigation, claim, proceeding or other action in respect of
which indemnification is being sought (each, a "Claim"), the Indemnified Party
shall notify the party against whom indemnification pursuant to this Section 6
is being sought (the "Indemnifying Party") of the commencement thereof; but the
omission to so notify the Indemnifying Party shall not relieve it from any
liability that it otherwise may have to the Indemnified Party, except to the
extent that the Indemnifying Party is materially prejudiced and forfeits
substantive rights and defenses by reason of such failure. In



                                       9
<PAGE>



connection with any Claim as to which both the Indemnifying Party and the
Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to
employ one separate legal counsel and to participate in the defense of such
Claim, and the Indemnifying Party shall bear the reasonable fees, out-of-pocket
costs and expenses of such separate legal counsel to the Indemnified Party if
(and only if): (i) the Indemnifying Party shall have agreed to pay such fees,
costs and expenses, (ii) counsel to the Indemnified Party shall reasonably have
concluded that representation of the Indemnified Party and the Indemnifying
Party by the same legal counsel would not be appropriate due to actual or, as
reasonably determined by legal counsel to the Indemnified Party, potentially
differing interests between such parties in the conduct of the defense of such
Claim, or if there may be legal defenses available to the Indemnified Party that
are in addition to or disparate from those available to the Indemnifying Party,
or (iii) the Indemnifying Party shall have failed to employ legal counsel
reasonably satisfactory to the Indemnified Party within a reasonable period of
time after notice of the commencement of such Claim. If the Indemnified Party
employs separate legal counsel in circumstances other than as described in
clauses (i), (ii) or (iii) above, the fees, costs and expenses of such legal
counsel shall be borne exclusively by the Indemnified Party. Except as provided
above, the Indemnifying Party shall not, in connection with any Claim in the
same jurisdiction, be liable for the fees and expenses of more than one firm of
counsel for the Indemnified Party (together with appropriate local counsel). The
Indemnified Party shall not, without the prior written consent of the
Indemnifying Party (which consent shall not unreasonably be withheld), settle or
compromise any Claim or consent to the entry of any judgment that does not
include an unconditional release of the Indemnifying Party from all liabilities
with respect to such Claim or judgment.

         (d) Contribution. If the indemnification provided for in this Section 6
is unavailable to or insufficient to hold harmless an Indemnified Person under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
Indemnifying Party shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party and the Indemnified Party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such Indemnifying Party and
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such Indemnifying Party or by such Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 6(d) were determined by
pro rata allocation (even if the Investors or any underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 6(d).
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
shall be deemed to include any legal or other fees or 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 Securities Act) shall be



                                       10
<PAGE>



entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The obligations of the Investors and any underwriters in this
Section 6(d) to contribute shall be several in proportion to the percentage of
Registrable Securities registered or underwritten, as the case may be, by them
and not joint.

         (e) Notwithstanding any other provision of this Section 6, in no event
shall any (i) Investor be required to undertake liability to any person under
this Section 6 for any amounts in excess of the dollar amount of the net
proceeds to be received by such Investor from the sale of such Investor's
Registrable Securities pursuant to any Registration Statement under which such
Registrable Securities are to be registered under the Securities Act.

         (f) The obligations of the Company under this Section 6 shall be in
addition to any liability that the Company may otherwise have to any Indemnified
Person and the obligations of any Indemnified Person under this Section 6 shall
be in addition to any liability that such Indemnified Person may otherwise have
to the Company. The remedies provided in this Section 6 are not exclusive and
shall not limit any rights or remedies that may otherwise be available to an
indemnified party at law or in equity.

7. Rule 144. 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; and

         (b) use all commercially reasonable efforts to file with the Commission
in a timely manner all reports and other documents required to be filed by the
Company pursuant to Section 13 or 15(d) under the Exchange Act; and, if at any
time it is not required to file such reports but in the past had been required
to or did file such reports, it will, upon the request of any Investor, make
available other information as required by, and so long as necessary to permit
sales of, its Registrable Securities pursuant to Rule 144.

8. Assignment. The rights to have the Company register Registrable Securities
pursuant to this Exhibit C may be assigned or transferred only with the prior
written consent of the Company (which consent shall not be unreasonably withheld
or delayed), and any such assignment or transfer without such consent shall be
void and of no effect. Notwithstanding the foregoing, such consent of the
Company shall not be required with respect to: (i) any assignment or transfer of
Registrable Securities to an Affiliate of Investor, including for this purpose
if Investor is an investment company, any fund or account advised by Investor's
investment adviser or any Affiliate thereof; or (ii) any assignment or transfer
of all of the Registrable Securities owned by an Investor. In the event of any
such permitted assignment or transfer by the Investors to any permitted
transferee of all or any portion of such Registrable Securities such transfer
will be allowed only if: (a) the Investor agrees in writing with the transferee
or assignee to assign such rights, and a copy of such agreement is furnished to
the Company within a reasonable time after such assignment, (b) the Company is,
within a reasonable time after such transfer or assignment, furnished with
written notice of (i) the name and address of such transferee or assignee and
(ii) the securities with respect to which such registration rights are being
transferred or assigned, (c)



                                       11
<PAGE>



immediately following such transfer or assignment, the securities so transferred
or assigned to the transferee or assignee constitute Restricted Securities, (d)
at or before the time the Company received the written notice contemplated by
clause (b) of this sentence the transferee or assignee agrees in writing with
the Company to be bound by all of the provisions contained herein, and (e) the
Company is furnished with an opinion of counsel, which counsel and opinion shall
be reasonably satisfactory to the Company, to the effect that the permitted
assignment would be in compliance with the Securities Act and State Acts.

9. Amendment and Waiver. Any provision of this Exhibit C may be amended and the
observance thereof may be waived (either generally or in a particular instance
and either retroactively or prospectively), only with the written consent of the
Company and Investors who hold a majority interest of the Registrable
Securities. Any amendment or waiver effected in accordance with this Section 9
shall be binding upon each Investor and the Company.

10. Miscellaneous.

         (a) A person or entity shall be deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

         (b) Except as may be otherwise provided herein, any notice or other
communication or delivery required or permitted hereunder shall be in writing
and shall be delivered personally or sent by certified mail, postage prepaid, or
by a nationally recognized overnight courier service as follows, and shall be
deemed given three days following the date of mailing, in the case of a notice
sent by certified mail, or, in all other cases, when actually received.

          If to the Company, to:    Mobility Electronics, Inc.
                                    17800 N. Perimeter Drive, Suite 200

                                    Attention: Chief Financial Officer


          If to the Investors, to:  Each Investor at the address provided in its
                                    executed Stock Purchase Agreement

         The Company or any Investor may change the foregoing address by notice
given pursuant to this Section 10(b).

         (c) Failure of any party to exercise any right or remedy under this
Exhibit C or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

         (d) This Exhibit C shall be governed by and interpreted in accordance
with the laws of the State of Delaware, without regard to the conflict of laws
provisions thereof.

         (e) If any term, provision, covenant or restriction of this Exhibit C
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. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

         (f) 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 Exhibit C or otherwise conflicts with the
provisions hereof. The restrictions on the Company's rights to grant
registration rights under this paragraph shall terminate on the date all
Registrable Securities have been registered pursuant to a Registration Statement
that has been declared effective by the Commission.

         (g) This Exhibit C and the various Stock Purchase Agreements constitute
the entire agreement among the parties hereto with respect to the subject matter
hereof. There are no restrictions, promises, warranties or undertakings, other
than those set forth or referred to herein. This Exhibit C and such Stock
Purchase Agreements supersede all prior agreements and undertakings among the
parties hereto with respect to the subject matter hereof.

         (h) Subject to the requirements of Section 8 hereof, this Exhibit C
shall inure to the benefit of and be binding upon the successors and assigns of
each of the parties hereto.

         (i) All pronouns and any variations thereof refer to the masculine,
feminine or neuter, singular or plural, as the context may require.

         (j) The headings in this Exhibit C are for convenience of reference
only and shall not limit or otherwise affect the meaning thereof.
