     This Series C Preferred Stock and Warrant Purchase Agreement (the
"Agreement") is made as of the 29th day of October, 1999, by and between
Mobility Electronics, Inc., a Delaware corporation (the "Company"), and Seligman
Communications and Information Fund, Inc. (the "Purchaser").

     The parties hereby agree as follows:

     1. PURCHASE AND SALE OF PREFERRED STOCK AND WARRANT.

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

agrees to purchase at the Closing (as defined below) and the Company agrees to
sell and issue to Purchaser at the Closing 333,333 shares of Series C Preferred
Stock at a purchase price of $6.00 per share; provided, however, that to the
extent any shares of Series C Preferred Stock are sold by the Company at a price
less than $6.00 per share, Purchaser will receive, and the Company agrees to

amount of Purchaser's original investment divided by such lower issuance price
minus (ii) the aggregate number of shares of Series C Preferred Stock then
issued to Purchaser (subject to adjustment for all stock splits, stock

Agreements or the right of the Company to enter into them, or to consummate the
transactions contemplated hereby or thereby, or that might result, either
individually or in the aggregate, in any material adverse changes in the assets,
condition or affairs of the Company, financially or otherwise, or any change in
the current equity ownership of the Company, nor is the Company aware that there
is any basis for the foregoing. The foregoing includes, without limitation,
actions pending or to the best knowledge of the Company threatened in writing
involving the prior employment of any of the Company's employees, their use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers. Neither the Company nor
any of its subsidiaries is a party or subject to the provisions of any order,

        2.8 INTELLECTUAL PROPERTY. The Company owns or possesses sufficient
title and ownership of or licenses to all patents, trademarks, service marks,

There are no outstanding options, licenses or agreements of any kind relating to
the foregoing, nor is the Company bound by or a party to any options, licenses
or agreements of any kind with respect to the patents, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, information and other
proprietary rights and processes of any other person or entity other



                                     Page 4
<PAGE>

than such licenses or agreements arising from the purchase of "off the shelf" or
standard commercial products. The Company has not received any communications
alleging that the Company has violated or, by conducting its business, would
violate any of the patents, trademarks, service marks, trade names, copyrights,
trade secrets or other proprietary rights or processes of any other person or
entity. The Company, to the best of its knowledge, is not aware that any of its
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of such employee's best efforts to promote the interest of the Company
or that would conflict with the Company's business. To the best knowledge of the
Company, neither the execution or delivery of this Agreement, nor the carrying
on of the Company's business by the employees of the Company, nor the conduct of
the Company's business as proposed, will conflict with or result in a breach of
the terms, conditions, or provisions of, or constitute a default under, any
contract, covenant or instrument under which any such employee is now obligated.
The Company does not believe it is or will be necessary to use any inventions of
any of its employees (or persons it currently intends to hire) made prior to
their employment by the Company.

        2.9 COMPLIANCE WITH OTHER INSTRUMENTS.

            (a) The Company is not in violation or default of any provisions of

and effect as of the Closing Date) or (ii) any instrument, judgment, order,
writ, decree or contract to which it is a party or by which it is bound, the
violation of, or default, which would have a material adverse effect on the
Company, or, to the best knowledge of the Company, of any provision of federal
or state statute, rule or regulation applicable to the Company. The execution,
delivery and performance of the Agreements and the consummation of the
transactions contemplated hereby or thereby will not result in any such
violation or be in conflict with or constitute, with or without the passage of
time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company.

            (b) The Company has avoided every condition, and has not performed
any act, the occurrence of which would result in the Company's loss of any right
granted under any license, distribution agreement or other agreement.

agreements explicitly contemplated by the Agreements, there are no agreements,
understandings, instruments, contracts or proposed

<PAGE>

which it is bound that involve (i) obligations (contingent or otherwise) of, or
payments to, the Company or any of its subsidiaries in excess of, $100,000, (ii)
the license of any patent, copyright, trade secret or other proprietary right to
or from the Company or any of its subsidiaries, (iii) the grant of rights

distribute, market or sell its products; or (iv) indemnification by the Company
with respect to infringement of proprietary rights (other than indemnification
obligations arising from purchase or sale agreements entered into in the
ordinary course of business).

            (c) Neither the Company nor any of its subsidiaries has (i) declared
or paid any dividends, or authorized or made any distribution upon or with
respect to any class or series of its capital stock, (ii) incurred any
indebtedness for money borrowed or incurred any other liabilities individually

information that Purchaser has requested for deciding whether to acquire the
Stock and the Warrant and all information that the Company believes is
reasonably necessary to enable the Purchaser to make such a decision, including
the Company's 1999 Company Overview, dated September 1999 (the "Company
Overview"). No representation or warranty of the Company contained in this
Agreement and the exhibits attached hereto, any certificate furnished or to be
furnished to Purchaser at the Closing, or the Company Overview (when read
together) contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained herein or
therein not misleading in light of the circumstances under which they were made.
To the extent the Company Overview was prepared by management of the Company,
the Company Overview and the financial and other projections contained in the
Company Overview and other written information provided to the Purchaser were
prepared in good faith (with the exception of information prepared by third
party sources and identified as such in the Company Overview or other written
information and to which the Company makes no representation except that it has
no basis to believe such sections are inaccurate); however, the Company does not
warrant that it will achieve such projections.

        2.12 NO CONFLICT OF INTEREST. The Company is not indebted, directly or
indirectly, to any of its officers or directors or to their respective spouses
or children, in any amount whatsoever other than in connection with expenses or
advances of expenses incurred in the ordinary course of business or relocation
expenses of employees which amount does not in the aggregate exceed $50,000.
None of the Company's officers or directors, or any members of their immediate
families, are, directly or indirectly, indebted to the Company (other than in
connection with purchases of the



                                    Page 6
<PAGE>

Company's stock) or to the best knowledge of the Company have any direct or
indirect ownership interest in any firm or corporation with which the Company is
affiliated or with which the Company has a business relationship, or any firm or
corporation which competes with the Company except that officers, directors
and/or stockholders of the Company may own stock in (but not exceeding two
percent of the outstanding capital stock of) any publicly traded company that
may compete with the Company. None of the Company's officers or directors or any
members of their immediate families are, directly or indirectly, interested in
any material contract with the Company. The Company is not a guarantor or
indemnitor of any indebtedness of any other person, firm or corporation.

        2.13 RIGHTS OF REGISTRATION AND VOTING RIGHTS. Except as contemplated in
the Investors' Rights Agreement, the Company has not granted or agreed to grant
any registration rights, including piggyback rights, to any person or entity. To
the best knowledge of the Company, no stockholder of the Company has entered
into any agreements with respect to the voting of capital shares of the Company.

        2.14 TITLE TO PROPERTY AND ASSETS. The Company owns its property and
assets free and clear of all mortgages, liens, loans and encumbrances, except
such encumbrances and liens which arise in the ordinary course of business and
do not materially impair the Company's ownership or use of such property or
assets. With respect to the property and assets it leases, the Company is in
compliance with such leases and, to its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances. The Company is in compliance
with all material terms of each material lease to which it is a party or
otherwise bound.

        2.15 FINANCIAL STATEMENTS. The Company has made available to Purchaser
the financial statements set forth in the Company Overview (collectively, the
"Financial Statements"). The Financial Statements have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis throughout the periods indicated, except that the unaudited Financial
Statements may not contain all footnotes required by generally accepted
accounting principles. The Financial Statements fairly present the financial
condition and operating results of the Company as of the dates, and for the
periods, indicated therein, subject to normal year-end audit adjustments. Except
as set forth in the Financial Statements, the Company has no material
liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to June 30, 1999 and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and
not required under generally accepted accounting principles to be reflected in
the Financial Statements, which, in both cases, individually or in the aggregate
are not material to the financial condition or operating results of the Company.

Company pending, or to the best knowledge of the Company threatened, which could
have a material adverse effect on the assets, properties, financial condition,
operating results, or business of the Company, nor is the Company aware of any
labor organization activity involving its employees. The Company is not aware
that any officer or key employee, or that any group of key employees, intends to
terminate their employment with the Company, nor does the Company have a present
intention to terminate the employment of any of the foregoing. The employment of
each officer and employee of the Company is terminable at the will of the

     3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser hereby represents
and warrants to the Company that:

        3.1 AUTHORIZATION. Purchaser has full power and authority to enter into
this Agreement. The Agreements, when executed and delivered by Purchaser, will
constitute valid and legally binding obligations of Purchaser, enforceable in
accordance with their terms, except (a) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, and any other
laws of general application affecting enforcement of creditors' rights
generally, and as limited by laws relating to the availability of a specific
performance, injunctive relief, or other equitable remedies, or (b) to the
extent the indemnification provisions contained in the Investors' Rights
Agreement may be limited by applicable federal or state securities laws.

        3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with
Purchaser in reliance upon Purchaser's representation to the Company, which by
Purchaser's execution of this Agreement Purchaser hereby confirms, that the
Securities to be acquired by Purchaser will be acquired for investment for
Purchaser'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 Purchaser has no present


                                    Page 11
<PAGE>

intention of selling, granting any participation in, or otherwise distributing
the same. By executing this Agreement, Purchaser further represents that
Purchaser does not presently have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participation to such
person or to any third person, with respect to any of the Securities. Purchaser
has not been formed for the specific purpose of acquiring the Securities.

        3.3 DISCLOSURE OF INFORMATION. Purchaser has had an opportunity to
discuss the Company's business, management, financial affairs and the terms and
conditions of the offering of the Stock and Warrant with the Company's
management and has had an opportunity to review the Company's facilities.
Purchaser understands that such discussions, as well as the Company Overview and
any other written information delivered by the Company to Purchaser, were
intended to describe the aspects of the Company's business which it believes to
be material.

        3.4 RESTRICTED SECURITIES. Purchaser understands that the Securities
have not been, and will not be, registered under the Securities Act, by reason
of a specific exemption from the registration provisions of the Securities Act
which depends upon, among other things, the bona fide nature of the investment
intent and the accuracy of Purchaser's representations as expressed herein.
Purchaser understands that the Securities are "restricted securities" under
applicable U.S. federal and state securities laws and that, pursuant to these
laws, Purchaser must hold the Securities indefinitely unless they are registered
with the Securities and Exchange Commission and qualified by state authorities,
or an exemption from such registration and qualification requirements is
available. Purchaser acknowledges that the Company has no obligation to register
or qualify the Securities for resale except as set forth in the Investors'
Rights Agreement. Purchaser 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 Purchaser's control, and which the Company is under no
obligation and may not be able to satisfy.

        3.5 NO PUBLIC MARKET. Purchaser understands that no public market now
exists for any of the securities issued by the Company, and that the Company has
made no assurances that a public market will ever exist for the Securities.

        3.6 LEGENDS. Purchaser understands that the Securities, and any
securities issued in respect of or exchange for the Securities, may bear one or
all of the following legends (or substantially similar legends):
