                               REGISTRATION RIGHTS

         1. DEFINITIONS. For purposes of this Exhibit H:

                  The term "ACT" means the Securities Act of 1933, as amended.

                  The term "HOLDER" means any person owning or having the right
         to acquire Registrable Securities or any assignee thereof in accordance
         with Section 6 hereof.

                  The term "1934 ACT" shall mean the Securities Exchange Act of
         1934, as amended.

                  The term "REGISTER," "REGISTERED," and "REGISTRATION" refer to
         a registration effected by preparing and filing a registration
         statement or similar document in compliance with the Act, and the
         declaration or ordering of effectiveness of such registration statement
         or document.

                  The term "REGISTRABLE SECURITIES" has the meaning set forth in
         the Agreement, as well as any Common Stock issued as a dividend or
         other distribution with respect to, or in exchange for or in
         replacement of, such Registrable Securities, excluding in all cases,
         however, any Registrable Securities (I) sold by a person in a
         transaction in which his rights pursuant to this Exhibit H are not
         assigned or (II) registered under the Act, the registration statement
         in connection therewith has been declared effective, and such shares
         have been disposed by such holder pursuant to such registration
         statement; provided, however, that any such securities shall cease to
         be Registrable Securities if the registration rights granted hereunder
         are not transferred in accordance with the provisions of Section 6
         below.

                  The term "SEC" shall mean the Securities and Exchange
         Commission.

                  All other capitalized terms used herein which are not defined
         herein shall have the meaning given elsewhere in this Exhibit or in the
         Agreement and Plan of Merger, as applicable.

         2. OBLIGATIONS OF PARENT. Whenever Parent effects the registration of
any Registrable Securities, Parent shall, as expeditiously as reasonably
possible:

            (a) Prepare and file with the SEC on any appropriate form a
registration statement with respect to the Registrable Securities proposed to be
registered and use all commercially reasonable efforts to cause such
registration statement to become effective as soon as practicable thereafter.

            (b) Unless such registration is a firm commitment underwriting,
prepare and file with the SEC such amendments (including post-effective
amendments) and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective and to comply with the provisions of the Act with respect to
the disposition of all Registrable Securities covered by such registration
statement,

                                       1

<PAGE>

until such time as Holder is able to sell all of the Registrable Securities held
by Holder in a single three-month period in compliance with Rule 144.

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

            (d) Use all commercially reasonable efforts to register or qualify
all Registrable Securities and other securities covered by such registration
statement under such other securities or "blue sky" laws of such jurisdictions
as the underwriter or such sellers (not to exceed ten jurisdictions) shall
reasonably request and do any and all other acts and things as may be reasonably
necessary to consummate the disposition in such jurisdictions of the Registrable
Securities covered by such registration statement, except that Parent shall not
for any such purpose be required to qualify generally to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified, or to
subject itself to taxation in respect of doing business in any such
jurisdiction, or to consent to general service of process in any such
jurisdiction.

            (e) Immediately notify each seller of Registrable Securities covered
by such registration statement, at any time when a prospectus relating thereto
is required to be delivered under the 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 any
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing or if it
is necessary, in the opinion of counsel to Parent, to amend or supplement such
prospectus to comply with law, and at the request of any such seller prepare and
deliver to such seller a reasonable number of copies of a supplement to or any
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not 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 not misleading in the light of the circumstances then existing and shall
otherwise comply in all material respects with law and so that such prospectus,
as amended or supplemented, will comply with law.

            (f) Otherwise use all commercially reasonable efforts to comply with
all applicable rules and regulations of the SEC.

            (g) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

            (h) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange or automated trading system
on which similar securities issued by Parent are then listed.

                                       2

<PAGE>

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

         3. FURNISH INFORMATION. Any selling Holder shall furnish to Parent such
information regarding itself, the Registrable Securities held by it, and the
intended method of disposition of such securities as shall be required to effect
the registration of such Holder's Registrable Securities.

         4. EXPENSES OF REGISTRATION. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Exhibit H, including,
without limitation, all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for Parent (but excluding
underwriter's commissions, fees and discounts and any fees or expenses of others
employed or retained by a selling Holder) shall be borne by Parent.

         5. INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement pursuant to this Exhibit H:

            (a) To the extent permitted by law, Parent will indemnify and hold
harmless each Holder, any underwriter (as defined in the Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Act or the 1934 Act against any losses, claims, damages, or
liabilities, joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by Parent of the Act, the 1934 Act, any state securities law or any
rule or regulation promulgated under the 1934 Act or any state securities law;
and, subject to subsection 5(c) below, Parent will reimburse each such Holder,
underwriter or controlling person, as incurred, any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 5(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of Parent (which consent shall not be
reasonably withheld), nor shall Parent be liable in any such case for any such
loss, claim, damage, liability, or action to the extent that it arises out of or
is based upon a Violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

            (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless Parent, each of its directors, each of its officers
who has signed the registration statement, each person, if any, who controls
Parent within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, and any agent of Parent, against any losses,

                                       3

<PAGE>

claims, damages, or liabilities joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such Holder
expressly for use in connection with such registration; and each such Holder
will pay, as incurred, any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection 5(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 5(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be reasonably
withheld; provided, that, in no event shall any indemnity under this subsection
5(b) exceed the gross proceeds from the offering received by such Holder.

            (c) Promptly after receipt by an indemnified party under this
Section 5 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 5, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
receiving similar notice, to assume the defense thereof with counsel reasonably
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding; otherwise, the indemnified party shall be
responsible for the fees and expenses of its counsel. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 5.

            (d) Except as provided in the last sentence of subsection 5(c)
above, if the indemnification provided for in this Section 5 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. 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.

                                       4

<PAGE>

            (e) Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

            (f) The obligations of Parent and Holders under this Section 5 shall
survive the completion of any offering of Registrable Securities pursuant to a
registration statement pursuant to this Exhibit H.

         6. ASSIGNMENT OF REGISTRATION RIGHTS. The registration rights of the
Holders may be assigned (but only with all related obligations) by a Holder to a
transferee or assignee of such securities who purchases from such Holder at
least 100,000 shares of Registrable Securities (subject to appropriate
adjustment for stock splits, stock dividends, combinations and other
recapitalizations), provided: (a) Parent is promptly after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; (b) such transferee or assignee agrees in writing to be bound by
and subject to the terms and conditions of this document, including without
limitation the provisions of the Lock-Up Agreement; and (c) such assignment
shall be effective only if immediately following such transfer the further
disposition of such securities by the transferee or assignee is restricted under
the Act.

         7. TERMINATION OF REGISTRATION RIGHTS. Notwithstanding anything in this
Exhibit H to the contrary, no Holder shall be entitled to exercise any right
provided for in this Exhibit H at such time as such Holder is able to sell all
of such Holder's Registrable Securities in a single three-month period in
compliance with Rule 144.

                                       5<PAGE>
                                                                    EXHIBIT 4.34

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE. NO SALE OR DISPOSITION MAY BE
EFFECTED EXCEPT IN COMPLIANCE WITH RULE 144 UNDER SAID ACT OR AN EFFECTIVE
REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE HOLDER
SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE
ACT OR RECEIPT OF A NO-ACTION LETTER FROM THE SECURITIES AND EXCHANGE
COMMISSION.

                           MOBILITY ELECTRONICS, INC.

                    CONVERTIBLE SUBORDINATED PROMISSORY NOTE

certain subsidiaries of the Company and Silicon Valley Bank, as amended, and as
it may be further amended, supplemented or otherwise modified from time to time,

2005; provided, however, that if any portion of the principal amount of this
Note is converted into shares of Common Stock or is prepaid, as provided herein,
then the balance of the principal remaining at such time shall be reduced in the
amount of the conversion or prepayment amount, and shall be subtracted from the
above principal payments starting from the last payment date and working
forward.

         3. INTEREST PAYMENTS. Accrued but unpaid interest on the unpaid
principal balance of this Note shall be payable at such times as the principal
payments are due in Section 2 above, and shall continue until such principal has
been repaid.

         4. PREPAYMENT. Subject to the conversion rights set forth in Section 6
below, at the option of the Company, the unpaid principal balance of this Note
may be prepaid in whole or in part from time to time, at any time after December

Prepayment Date to the Holder of this Note at its address as provided in Section
18 below.

         5. OFFSET. The Holder hereby agrees that the principal amount due
hereunder shall be subject to offset for fifty percent (50%) of any taxes owed
by the Holder pursuant to Section 7 of the Compromise Settlement Agreement,
dated as of November 13, 2002, entered into among the Holder, the Company,
Portsmith, Inc., and certain other persons (the "Settlement Agreement"), and not
paid by the Holder within ten (10) days following written notice thereof by the
Company to the Holder. If any amount owed pursuant to the previous sentence is
not paid within such ten (10) day period, then the Company may give the Holder
written notice of such offset, which offset shall be deemed to be effective as
of the date of such written notice. Any amounts offset under this Section 5
shall be deemed to come from the principal amount due hereunder, coming first
from the last scheduled principal payment and moving forward as necessary.

         6. CONVERSION. The then outstanding principal of this Note is
convertible, in whole or in part from time to time (in denominations of $10,000
or integral multiples thereof), at the option of the holder, into shares of
Common Stock, initially at the conversion price of $3.00 (the "Conversion
Price"), at any time prior to payment, prepayment or maturity, except that the
right to convert the portion of the principal amount of this Note called for
prepayment will terminate at the close of business on the third day preceding
the Prepayment Date and will be lost if not exercised prior to that time, unless
the Company defaults in making such prepayment. The Conversion Price and the
number of shares of Common Stock subject to this Note shall be subject to
adjustment from time to time as provided in Section 13 below and as follows:

            (a) If at any time or from time to time the Company shall subdivide
its outstanding shares of Common Stock, the Conversion Price in effect
immediately prior to such issuance or subdivision shall be proportionately
reduced. If the outstanding shares of Common Stock shall be combined into a
smaller number of shares, the Conversion Price in effect immediately prior to
such combination shall be proportionately increased.

                                       2
<PAGE>

            (b) If at any time or from time to time the Company shall declare a
dividend or make any other distribution upon any class or series of stock of the
Company payable in shares of Common Stock or securities convertible into shares
of Common Stock the Conversion Price and the number of shares to be obtained
upon exercise of this Note shall be proportionately adjusted to reflect the
issuance of any shares of Common Stock or convertible securities, as the case
may be, issuable in payment of such dividend or distribution.

            (c) If at any time or from time to time the Company undertakes any
capital reorganization, reclassification of the Common Stock, the consolidation
or merger of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the surviving corporation), or
the sale or other disposition of all or substantially all the properties and
assets of the Company to any other person, this Note shall, after such
reorganization, reclassification, consolidation, merger, sale or other
disposition, be convertible so that upon conversion the Holder shall procure, in
lieu of each of Common Stock, the kind and amount of shares of stock, other
securities, money or property receivable upon such reorganization,
reclassification, consolidation, merger, sale or other disposition by the holder
of one share of Common Stock issuable upon conversion of this Note had this Note
been converted immediately prior to such reorganization, reclassification,
consolidation, merger, sale or other disposition. The provisions of this
subsection (c) shall similarly apply to successive reorganizations,
reclassification, consolidations, mergers, sales or other dispositions.

            (d) No adjustment in the Conversion Price and/or the number of
shares of Common Stock subject to this Note need be made if such adjustment
would result in a change in the Conversion Price of less than ten cents ($0.10)
or a change in the number of subject shares of less than one-tenth (1/10th) of a
share. Any adjustment less than these amounts which is not made shall be carried
forward and shall be made at the time of and together with any subsequent
adjustment which, on a cumulative basis, amounts to an adjustment of at least
these amounts.

            (e) Upon the occurrence of each adjustment or readjustment of the
Conversion Price pursuant to this Section 6, the Company at its expense shall,
upon demand, promptly compute such adjustment or readjustment in accordance with
the term hereof and prepare and finish to the Holder a certificate setting forth
such adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Company shall, upon written request at
any time of the Holder, furnish or cause to be furnished to the Holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the then
effective Conversion Price and number of shares of Common Stock subject to this
Note, and (iii) the then effective amount of securities (other than Common
Stock) and other property, if any, which would be received upon conversion of
this Note.

         7. CONVERSION PROCEDURE. To exercise conversion rights and to obtain a
stock certificate, the Holder shall present this Note at the principal office of
the Company with a Conversion Form, in the form attached hereto as Exhibit A,
duly executed by the Holder. As soon as practicable after the submission of this
Note and the duly executed Conversion Form, the Company will cause to be issued
in the name of and delivered to the Holder a certificate or certificates for the
number of full shares of Common Stock to which the Holder shall be entitled on
such conversion. In the case of a partial conversion, the Company shall deliver
to the Holder a Note in principal amount equal to the unconverted portion of the
principal amount hereof.

                                       3
<PAGE>

From and after the date on which this Note and a duly executed Conversion Form
are surrendered to the Company (the "Conversion Date"), the Holder shall be
deemed to be the record Holder of all shares of Common Stock to which the Holder
shall be entitled on such conversion for all purposes, and all rights,
preferences and privileges of such shares of Common Stock shall be attributable
to the Holder.

         8. FRACTIONAL SHARES. Fractional shares of Common Stock will not be
issued upon conversion, but, in lieu thereof the Company will pay a cash
adjustment based upon the fair market value of a share of Common Stock. The fair
market value shall be the closing price of the Common Stock on the applicable
exchange or market on which the Common Stock is primarily trading at the time of
such determination, and if the Common Stock is not then trading, the fair market
value shall be such price as the Board of Directors of the Company determines in
its sole and absolute discretion.

         9. METHOD OF PAYMENT. Any payment made under this Note, whether of
principal or interest, shall be made by the Company to the Holder on the date
specified or provided herein and shall be delivered by means of check or wire
transfer of immediately available funds to an account specified by the Holder.

         10. SUBORDINATION. The indebtedness evidenced by the Note shall be
subordinate to the prior payment of the Designated Senior Debt. Upon any payment
or distribution of assets of the Company to creditors upon any dissolution,
winding up, liquidation, reorganization, recapitalization or readjustment of the
Company or its property or securities, payment of the principal of and interest
on this Note shall be subordinated to the extent and manner set forth herein, to
the prior payment in full of the Designated Senior Debt. No payments of
principal or interest on this Note may be made by or on behalf of the Company
(i) at any time when there exists (or after giving effect to the payment thereof
there would exist) an event of default, or a condition or event which with
notice or lapse of time or both would constitute an event of default, under the
Designated Senior Debt or pursuant to any agreement under which the Designated
Senior Debt has been issued, (ii) if full payment of amounts then due for
principal and interest on the Designated Senior Debt has not been made or duly
provided for; or (iii) if such payment would result in a default under the
Designated Senior Debt. The subordination rights of holders of Designated Senior
Debt will not be prejudiced or impaired by acts or failures to act by the
Company or by the Holder. The subordination of this Note as set forth above
shall not, however, prevent the occurrence of any Event of Default (as defined
below) or impair, as between the Company, the Holder and creditors of the
Company other than holders of Designated Senior Debt, the obligations of the
Company to make payments on this Note in accordance with its terms. The payment
of cash, property or securities (other than Common Stock and other securities
that are junior to the Designated Senior Debt) upon conversion of this Note
shall constitute payment on this Note and therefore shall be subject to the
subordination provisions hereof.

         11. RESERVATION OF SECURITIES. So long as this Note is outstanding, the
Company covenants that it will reserve from its authorized and unissued shares
of Common Stock a sufficient number of shares to provide for the delivery of
Common Stock pursuant to the conversion provisions of this Note.

                                       4
<PAGE>

         12. EVENTS OF DEFAULT. The following will be Events of Default
hereunder (each, an "Event of Default"): (i) failure by the Company to pay any
principal or interest payment when due, whether or not such payment is
prohibited by Section 10 hereof, and such failure continues for a period of five
(5) consecutive days after delivery of written notice from the Holder to the
Company of such failure; (ii) failure by the Company to perform any other
covenant contained herein, if the same has continued for a period of thirty (30)
consecutive days after delivery of written notice from the Holder to the Company
of such failure; or (iii) the dissolution, winding up or liquidation of the
Company or the insolvency of or the appointment of an assignee for the benefit
of creditors of, or of a receiver for, the Company, or a petition in bankruptcy
shall be filed either by or against the Company, and the same shall not be
dismissed within sixty (60) days.

         13. ACCELERATION UPON DEFAULT. If an Event of Default shall occur and
be continuing: (i) which is an event of bankruptcy, insolvency or reorganization
of the Company, the maturity of this Note shall immediately accelerate without
any act on the part of the Holder, including demand for payment thereof and
notice to the Company, which demand and notice are hereby expressly waived; or
(ii) which is not an event of bankruptcy, insolvency or reorganization of the
Company, the Holder may accelerate the maturity of this Note five business days
after written notice of such Event of Default is received by the Company. In
addition, if an Event of Default has occurred and has continued for at least
thirty (30) days after written notice of such occurrence from the Holder to the
Company (the "Notice Effective Date"), then thereafter during the continuance of
such Event of Default: (i) the interest rate on this Note shall be fifteen
percent (15%) per annum; and (ii) the Conversion Price shall be sixty percent
(60%) of the Current Market Price of the Common Stock as of the Notice Effective
Date. The term "Current Market Price" shall mean the per share price of the
Common Stock on the trading day immediately prior to the Notice Effective Date
and shall be: (i) if the principal trading market for such securities is a
national or regional securities exchange, the closing price on such exchange on
such day; or (ii) if sales prices for shares of Common Stock are reported by the
Nasdaq National Market System or Small Cap Market System (or a similar system
then in use), the last reported sales price so reported on such day; or (iii) if
neither (i) nor (ii) above are applicable, and if bid and ask prices for shares
of Common Stock are reported in the over-the-counter market by Nasdaq (or, if
not so reported, by the National Quotation Bureau), the average of the high bid
and low ask prices so reported on such day. Notwithstanding the foregoing, if
there is no reported closing price, last reported sales price, or bid and ask
prices, as the case may be, then the "Current Market Price" shall be determined
as of the latest date prior to the Notice Effective Date day for which such
closing price, last reported sales price, or bid and ask prices, as the case may
be, are available, unless such securities have not been traded on an exchange or
in the over-the-counter market for 30 or more days immediately prior to the
Notice Effective Date, in which case the Current Market Price shall be
determined in good faith by, and reflected in a formal resolution of, the Board
of Directors of the Company.

         14. RIGHTS AND REMEDIES. If the Company fails to comply with the terms
of this Note, unless such failure shall have been waived in writing, and subject
to Section 13 hereof, the Holder may proceed to protect and enforce its rights
by suit in equity or action at law, whether for the specific performance of any
term contained in this Note or for an injunction against any breach of any such
term or in aid of the exercise of any power granted in this Note or may proceed

more of such actions. In the event that the Holder seeks to enforce its rights
under this Note, the prevailing party shall be entitled to recover reasonable

limitation, the fees, costs and expenses of attorneys, accountants and experts,
whether or not litigation is instituted, and including such fees, costs and
expenses.

of assignment (as applicable), and such surrendered Note shall promptly be
canceled. Upon any partial transfer, the Company shall deliver to the Holder a
Note in principal amount equal to portion of the principal amount which has not
been so transferred.

            (b) Upon receipt of evidence satisfactory to the Company of the
loss, theft, destruction or mutilation of this Note and (in the case of loss,
theft or destruction) of indemnification satisfactory to the Company, and upon
surrender and cancellation of this Note, if mutilated, the Company shall execute

         19. MAXIMUM LAWFUL RATE. It is the intent of the Company and the Holder
to conform to and contract in strict compliance with applicable usury law from
time to time in effect. In no way, nor in any event or contingency (including
but not limited to prepayment, default, demand for payment, or acceleration of
the maturity of any obligation), shall the rate of interest taken, reserved,
contacted for, charged or received under this Note exceed the highest lawful
interest rate permitted under applicable law. If the Holder shall ever receive
anything of value which is characterized as interest under applicable law and
which would apart from this provision be in excess of the highest lawful
interest rate permitted under applicable law, an amount equal to the amount
which would have been excessive interest shall, without penalty, be applied to
the reduction of the principal amount owing on this Note in the inverse order of
its maturity and not to the payment of interest, or refunded to the Company or
the other payor thereof if and to the extent such amount which would have been
excessive exceeds such unpaid principal. All interest paid or agreed to be paid
to the Holder shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full stated term

                                       7
<PAGE>

(including any renewal or extension) of this Note so that the amount of interest
on account of such obligation does not exceed the maximum permitted by
applicable law. As used in this Section, the term "applicable law" shall mean
the laws of the State of Delaware or the federal laws of the United States,
whichever laws allow the greater interest, as such laws now exist or may be
changed or amended or come into effect in the future.

         20. AMENDMENT; WAIVER. This Note may be modified, amended, waived or
terminated only by an instrument in writing signed by both the Company and the
Holder

LAWS PROVISIONS THEREOF. Any action or dispute from this Note shall be subject
to the exclusive jurisdiction of the Superior Court of the State of California,

any action or the expiration of any right required or granted herein shall be a
Saturday or a Sunday or shall be a legal holiday, then such action may be taken
or such right may be exercised on the next succeeding day not a Saturday, Sunday
