                  (e) The portion of Section 5.7 of the Loan Agreement that
currently reads as follows:

                     "The information in the Representations previously
                     submitted to Bank continues to be true and correct as of
                     the date hereof."


, hereby is amended and restated in its entirety to read as follows:

                     submitted to Bank continues to be true and correct as of
                     the July 2004 Amendment Date."

                  (f) Section 6.2(a)(ii) of the Loan Agreement, which currently
reads as follows:

                     "(ii) Monthly perpetual inventory reports for the Inventory
                     valued on a first-in, first-out basis at the lower of cost
                     or market (in accordance with GAAP) and such other
                     inventory reports as are requested by Bank in its good
                     faith business judgment, all within 20 days after the end
                     of each month. Notwithstanding the foregoing, Bank
                     understands that Borrower presently reports its inventory
                     on a standard cost basis and Borrower may continue to do so
                     until it converts its accounting system to enable it to
                     report its inventory on a first-in, first-out basis at the
                     lower of cost or market (in accordance with GAAP), which
                     Borrower shall do beginning with reports for the month of
                     April, 2003. Borrower's reports on a standard cost basis
                     shall be accompanied by variance data in form acceptable to
                     Bank showing variance to actual costs and other data as
                     Bank shall specify. In the event the Asset Based Terms are
                     in effect before Borrower reports its Inventory on a
                     first-in, first-out basis, the variance between standard
                     cost and actual cost shall be subject to a reserve
                     established by the Bank in its good faith business
                     judgment."


, hereby is amended and restated in its entirety to read as follows:

                     "(ii) From and after Bank's receipt of the "Designated
                     Inventory Appraisal" (as such term is defined in Section
                     1.1 of the Schedule), monthly perpetual inventory reports
                     for the Inventory, including any adjustments or reserves
                     made by Borrower in order to value Inventory at a first-in,
                     first-out basis at the lower of cost or market (in
                     accordance with GAAP), and such other inventory reports as
                     are requested by Bank in its good faith business judgment,
                     all within 20 days after the end of each month."

                  (g) Section 6.2(a)(iii) of the Loan Agreement, which currently
reads as follows:

                     "(iii) Within 20 days after the last day of each month,
                     Borrower will deliver to Bank a Borrowing Base Certificate
                     signed by a Responsible Officer in the form of Exhibit C,
                     provided that if the Asset Based Terms are in effect such
                     Borrowing Base Certificate shall be delivered to Bank
                     weekly as specified by Bank."

                     Accounts, and schedules of collections, all on Bank's
                     standard forms; provided, however, that Borrower's failure
                     to execute and deliver the same shall not affect or limit
                     Bank's security interest and other rights in all of
                     Borrower's Accounts. If requested by Bank, Borrower shall

                     receipts, bills of lading, and other evidence of delivery,
                     for any goods the sale or disposition of which gave rise to
                     such Accounts, and Borrower warrants the genuineness of all
                     of the fore-going. Borrower shall also furnish to Bank an
                     aged accounts receivable trial balance in such form and at
                     such intervals as Bank shall request. In addition, Borrower

                     chattel paper, security agreements, guarantees and other
                     documents and property evidencing or securing any Accounts,
                     immediately upon receipt thereof and in the same form as
                     received, with all necessary endorsements, all of which
                     shall be with recourse. Borrower shall also provide Bank
                     with copies of all credit memos from time to time on
                     request by Bank."

                     (iii), (iv), and (v), provided that if, in a following
                     month, the Borrower requests an Advance, Borrower shall
                     provide said reports at the time the request for the
                     Advance is made."


, hereby is deleted in its entirety.

                  (i) The portion of Section 6.9 of the Loan Agreement that
currently reads as follows:

                     "The sums received in such lockbox account shall be applied
                     to the outstanding monetary Obligations in such order as
                     Bank shall determine, and any excess will be deposited by

                     be deposited by Bank in Borrower's operating account at

                     judgment, elect to apply any or all sums received in such
                     lockbox account to the outstanding monetary Obligations in
                     such order as Bank shall determine or hold such sums as

                     Shelby Drive, Memphis, Tennessee 38118 (the "Tennessee
                     Warehouse"). Borrower previously has caused the
                     warehouseman or bailee in respect of the Tennessee
                     Warehouse to execute and deliver to Bank a bailee agreement
                     (in form and substance satisfactory to the Bank). Borrower
                     hereby covenants that Borrower promptly shall deliver
                     written notice to the Bank of any goods or other Collateral
                     of Borrower being in the possession of any other
                     warehouseman or other bailee. With respect to any goods or

                     warehouseman or other bailee located within the United
                     States, Borrower shall, promptly upon the Bank's request
                     therefor, use commercially reasonable efforts to deliver to
                     the Bank a bailee agreement (in form and substance
                     satisfactory to the Bank) duly executed by such
                     warehouseman or other bailee. In the event that the Bank
                     requests such a bailee agreement and Borrower uses such
                     efforts but does not succeed in delivering such a bailee
                     agreement, the Bank may (in its good faith business
                     judgment) maintain a reserve with respect to such warehouse
                     or other bailee location."

                  (m) Section 5.3 of the Loan Agreement, which currently reads
as follows:

                     "Except as shown in the Schedule, there are no actions or

                     Responsible Officers and legal counsel, threatened by or
                     against Borrower or any Subsidiary, which could reasonably
                     be expected to result in damages or costs to Borrower or
                     any Subsidiary of $100,000 or more, or in which an adverse
                     decision could reasonably be expected to cause a Material
                     Adverse Change."

                     could reasonably be expected to result in damages or costs
                     to Borrower or any Subsidiary of $100,000 or more, or in
                     which an adverse decision could reasonably be expected to
                     cause a Material Adverse Change."

                  (n) The portion of Section 6.2(b) of the Loan Agreement that
currently reads as follows:

                     "Such audits will be conducted no more often than every 6
                     months, provided that if the Asset Based Terms are in
                     effect, such audits may be conducted by Bank quarterly, and
                     if an Event of Default or an event which, with notice or
                     passage of time or both would constitute an Event of
                     Default, has occurred and is continuing, there shall not be
                     a limit on the number of such audits."


, hereby is amended and restated in its entirety to read as follows:

                     "Such audits will be conducted no more often than (a)
                     subject to the following proviso and clause (b) below, once
                     in any consecutive-6-month-period (which period commences
                     on or after the July 2004 Amendment Date), so long as no
                     Event of Default and no event which, with notice or passage
                     of time or both would constitute an Event of Default
                     ("Default") has occurred and is continuing, or (b) subject
                     to the following proviso, once in any

                     were outstanding at any time during such 12-month period
                     and no Default or Event of Default has occurred and is
                     continuing; provided, however, that any such audits
                     conducted upon the occurrence and during the continuation
                     of any Default or Event of Default shall not count toward

                     audits."


         3. LIMITED AND CONDITIONAL CONSENT TO SALE OF MOBILITY TEXAS, INC. Bank
hereby agrees to not unreasonably withhold its consent to the sale of all or
substantially all of the assets or capital stock of Mobility Texas, Inc.
(formerly known as Cutting Edge Software, Inc.); provided, however, that, as
conditions to the effectiveness of any such consent:

         (a) no Event of Default shall have occurred and be continuing, both
immediately before and immediately after the consummation of such sale;

         (b) such sale shall be in accordance (in all material respects) with
the terms and conditions of a commercially-reasonable, definitive purchase/sale
agreement relative thereto;

         (c) all consideration received by Borrower (in the case of a stock
sale) or Mobility Texas, Inc. (in the case of an asset sale) for such sale shall
be promptly delivered to Bank in the same form as received (with any and all
necessary endorsements): (i) in the case of monetary payments, to be applied to
(or held by Bank as cash security for) the outstanding monetary Obligations in
such order as Bank shall determine, and any excess will be deposited by Bank in
Borrower's operating account at Bank; and (ii) in all other cases, as additional
Collateral.

It is understood and agreed that such consent to such sale (the "Permitted
Mobility Texas Sale") does not constitute a waiver of any provision or term of
the Loan Documents restricting the sale or other disposition of assets of any
Borrower or any Guarantor in respect of any matter other than the Permitted
Mobility Texas Sale, nor a waiver of any other provision or term of the Loan
Agreement or any other Loan Document, nor an agreement to waive, in the future,
any provision or term of the Loan Documents restricting the sale or other
disposition of assets of any Borrower or any Guarantor in respect of any matter
other than the Permitted Mobility Texas Sale, nor a waiver of any other
provision or term of the Loan Agreement or any other Loan Document.

Concurrently with the effectiveness of such consent and the consummation of such
sale, Bank will (at Borrower's expense): (y) (1) release its security interests
(without recourse, representation, or warranty) in such assets or capital stock
that are sold pursuant to such sale, (2) authorize and authenticate in writing
the filing of UCC-2/3 Partial Releases relative to the applicable financing
statements of record in favor of the Bank, in form and substance reasonably
satisfactory to Bank and otherwise in suitable form for filing in the
appropriate governmental

offices, in order to reflect such release of security interests, and (3) execute
and deliver any other documents (in form and substance reasonably satisfactory
to Bank) reasonably requested by Borrower to effect or reflect such release of
security interests; and (z) if and to the extent that Borrower no longer owns
any capital stock of Mobility Texas, Inc. (formerly known as Cutting Edge
Software, Inc.), release Mobility Texas, Inc. (formerly known as Cutting Edge
Software, Inc.) from its guaranty of the Obligations in favor of Bank (except
that Borrower shall assume any and all obligations of Mobility Texas, Inc.
(formerly known as Cutting Edge Software, Inc.) under the Loan Documents to
reimburse Bank for costs and expenses and to indemnify Bank).

         4. FEES. In consideration for Bank entering into this Amendment and the
Amended and Restated Schedule, Borrower shall pay Bank the $50,000 facility fee
described in Section 3 of the Amended and Restated Schedule, concurrently with
the execution and delivery of this Amendment and the Amended and Restated
Schedule, which fee shall be non-refundable and in addition to all interest and
other fees payable to Bank under the Loan Documents. Bank is authorized to
charge said fees to Borrower's loan account.

         5. REPRESENTATIONS TRUE. Borrower represents and warrants to Bank that
all representations and warranties set forth in the Loan Agreement, as amended
hereby, are true and correct.

         6. GENERAL PROVISIONS. This Amendment, the Loan Agreement, any prior
written amendments to the Loan Agreement signed by Bank and Borrower, and the
other Loan Documents set forth in full all of the representations and agreements
of the parties with respect to the subject matter hereof and supersede all prior
discussions, representations, agreements and understandings between the parties
with respect to the subject hereof. Except as expressly amended herein (or as
amended and restated in the Loan Documents as expressly contemplated herein),
all of the terms and provisions of the Loan Agreement and all other Loan
Documents shall continue in full force and effect and the same are hereby
ratified and confirmed.

                       AMENDED AND RESTATED SCHEDULE 1 TO

                          LOAN AND SECURITY AGREEMENT

BORROWER(S):      MOBILITY ELECTRONICS, INC.
                  MOBILITY IDAHO, INC. (FORMERLY PORTSMITH, INC.)
                  MAGMA, INC.

DATED AS OF JULY 31, 2004 (THE "JULY 2004 AMENDMENT DATE")

This Amended and Restated Schedule 1 (this "Schedule") forms an integral part of
the Loan and Security Agreement, dated September 27, 2002 (as amended, restated,
supplemented, or otherwise modified from time to time (including without
limitation pursuant to the July 2004 Amendment referred to below), the "Loan
Agreement" or "this Agreement"), between Silicon Valley Bank ("Bank" or
"Silicon") and the borrower(s) named above (individually and collectively, and
jointly and severally, "Borrower"), and, effective as of the date hereof, this
Schedule amends and restates in its entirety the prior Schedule 1 to Loan and
Security Agreement, dated September 27, 2002 (as amended, restated,
supplemented, or otherwise modified from time to time prior to the date hereof),
between Bank and Borrower. This Schedule is the "Amended and Restated Schedule"
referred to in Section 1 of the Amendment to Loan Documents, dated as of even
date herewith, between Borrower and Bank (the "July 2004 Amendment") relative to
the Loan Agreement. (Capitalized terms used herein, which are not defined, shall
have the meanings set forth in the Loan Agreement.) The term "July 2004
Amendment Date" as defined above hereby is incorporated into the Loan Agreement.

1.    CREDIT LIMIT

      (Section 2.1.1):

      1.1   Subject to Sections 1.2 and 1.3 below, the Credit Limit shall be an
            amount not to exceed the lesser of (i) $10,000,000 at any one time
            outstanding (the "Committed Revolving Line") or (ii) the Borrowing
            Base (as defined below). As used herein, the term "Borrowing Base"
            means, as of any date of determination, the result of (a), (b), and
            (c) below:

            (a)   80% (the "Accounts Advance Rate" and also an "Advance Rate")
                  of the amount of Borrower's Eligible Accounts,

            plus

            (b)   the lesser of (1) or (2) below (the "Inventory Component"):

                  (1)   25% (the "Inventory Advance Rate" and also an "Advance
                        Rate") of the value of Borrower's Eligible Inventory (as
                        defined in Section 13.1 of the Loan Agreement),
                        calculated at the lower of cost or

SILICON VALLEY BANK                A&R SCHEDULE 1 TO LOAN AND SECURITY AGREEMENT


                        market value and determined on a first-in, first-out
                        basis, or

                  (2)   $2,000,000 (the "Inventory Sublimit"),

            minus

            (c)   Reserves for accrued interest and such other reserves as Bank
                  deems proper from time to time in its good faith business
                  judgment.

            Anything in the Loan Agreement to the contrary notwithstanding, in
            no event shall the aggregate outstanding amount of Advances and
            other Credit Extensions based on the Inventory Component exceed 20%
            (the "Inventory Percentage Limit" and also an "Advance Rate") of the
            aggregate amount of all Advances and other Credit Extensions
            outstanding hereunder.

            Anything in the Loan Agreement to the contrary notwithstanding, the
            Inventory Sublimit shall equal Zero Dollars ($-0-), unless and until
            Bank has received, on or after the July 2004 Amendment Date, the
            results of an appraisal of the Inventory completed by or on behalf
            of Bank, which results shall be satisfactory to Bank in its good
            faith business judgment (the "Designated Inventory Appraisal").

            Silicon may, from time to time, modify the Advance Rates, in its
            good faith business judgment, upon notice to the Borrower, based on
            changes in collection experience with respect to Accounts, its
            evaluation of the Inventory or other issues or factors relating to
            the Accounts, Inventory or other Collateral.

      1.2   Advances will be made separately to each Borrower, based on the
            Eligible Accounts and Eligible Inventory of each Borrower. Accounts
            and Inventory of Mobility Idaho, Inc. (formerly Portsmith, Inc.) and
            Magma, Inc. will not be "Eligible" unless and until they are
            approved by Bank in writing in its sole discretion.

      1.3   Credit Extensions Sublines under the Committed Revolving Line:

            (a) Letter of Credit Sublimit (Section 2.1.2): $2,500,000; provided,
            however, that the sum of the aggregate face amount of outstanding
            Letters of Credit, plus the FX Reserve, plus the aggregate amount of
            Obligations in respect of Cash Management Services, shall not at any
            time exceed $2,500,000.

            At the request of Borrower, Bank may, in its good faith business
            judgment, issue or arrange for the issuance of letters of credit for
            the account of Borrower, in each case in form and substance
            satisfactory

<PAGE>
SILICON VALLEY BANK                A&R SCHEDULE 1 TO LOAN AND SECURITY AGREEMENT

            to Bank in its sole discretion (collectively, "Letters of Credit").
            The Borrower agrees that the aggregate face amount of all
            outstanding Letters of Credit shall never exceed the lesser of the
            Letter of Credit Sublimit set forth above or the amount of Advances
            and other Credit Extensions which are from time to time available
            hereunder, and that the amount of outstanding Letters of Credit
            shall be reserved against Advances and other Credit Extensions which
            would otherwise be available hereunder. If at any time or for any
            reason the aggregate face amount of all outstanding Letters of
            Credit shall exceed the foregoing limit, Borrower shall immediately
            pay an amount equal to said excess to Bank, without notice or
            demand. Borrower shall pay all bank charges (including charges of
            Bank) for the issuance of Letters of Credit, together with such
            additional fees as Bank's letter of credit department shall charge
            in connection with the issuance of the Letters of Credit. Any
            payment by Bank under or in connection with a Letter of Credit shall
            constitute an Advance hereunder on the date such payment is made.
            Each Letter of Credit will have an expiry date of no later than 180
            days after the Revolving Maturity Date (except that a Letter of
            Credit issued to HIPRO Electronics may have an expiry date beyond
            said 180-day period). Regardless of the expiry date of any Letter of
            Credit, Borrower's reimbursement obligations with respect to all
            Letters of Credit (including without limitation those with expiry
            dates after the Revolving Maturity Date and the Letter of Credit
            issued to HIPRO Electronics) shall be secured by cash on terms
            acceptable to Bank on or before the Revolving Maturity Date if the
            term of this Agreement is not extended by Bank. Borrower hereby
            agrees to indemnify, save, and hold Bank harmless from any loss,
            cost, expense, or liability, including payments made by Bank,
            expenses, and reasonable attorneys' fees incurred by Bank arising
            out of or in connection with any Letters of Credit. Borrower agrees
            to be bound by the regulations and interpretations of the issuer of
            any Letters of Credit guarantied by Bank and opened for Borrower's
            account or by Bank's interpretations of any Letter of C redit issued
            by Bank for Borrower's account, and Borrower understands and agrees
            that Bank shall not be liable for any error, negligence, or mistake,
            whether of omission or commission, in following Borrower's
            instructions or those contained in the Letters of Credit or any
            modifications, amendments, or supplements thereto. Borrower
            understands that Letters of Credit may require Bank to indemnify the
            issuing bank for certain costs or liabilities arising out of claims
            by Borrower against such issuing bank. Borrower hereby agrees to
            indemnify and hold Bank harmless with respect to any loss, cost,
            expense, or liability incurred by Bank under any Letter of Credit as
            a result of Bank's indemnification of any such issuing bank. The
            provisions of this Agreement, as it pertains to Letters of Credit,
            and any other Loan Documents relating to Letters of Credit are
            cumulative.

SILICON VALLEY BANK           A&R SCHEDULE 1 TO LOAN AND SECURITY AGREEMENT

            (b) FX Sublimit: $2,500,000; provided, however, that the sum of the
            aggregate face amount of outstanding Letters of Credit, plus the FX
            Reserve, plus the aggregate amount of Obligations in respect of Cash
            Management Services, shall not at any time exceed $2,500,000.

            Borrower may enter into foreign exchange forward contracts with
            Bank, on its standard forms, under which Borrower commits to
            purchase from or sell to Bank a set amount of foreign currency more
            than one Business Day after the contract date (the "FX Forward
            Contracts"); provided that (1) at the time the FX Forward Contract
            is entered into, Borrower has Unfunded Availability (as defined
            below) under this Agreement in an amount at least equal to 10% of
            the amount of the FX Forward Contract; (2) the total FX Forward
            Contracts at any one time outstanding may not exceed 10 times the
            amount of the FX Sublimit set forth above. Bank shall have the right
            to withhold, from the Advances and other Credit Extensions otherwise
            available to Borrower under this Agreement, a reserve (which shall
            be in addition to all other reserves) in an amount equal to 10% of
            the total FX Forward Contracts from time to time outstanding (the
            "FX Reserve"), and in the event at any time there are insufficient
            Advances and other Credit Extensions available to Borrower for such
            reserve, Borrower shall deposit and maintain with Bank cash
            collateral in an amount at all times equal to such deficiency, which
            shall be held as Collateral for all purposes of this Agreement. Bank
            may, in its discretion, terminate the FX Forward Contracts at any
            time that an Event of Default occurs and is continuing. The FX
            Forward Contracts shall terminate upon the earlier of (a) the
            Revolving Maturity Date, or (b) any earlier effective date of
            termination of this Agreement (or such later date requested by
            Borrower as Bank may agree in writing in its sole discretion if and
            to the extent Borrower's Obligations in respect of the FX Forward
            Contracts are secured by cash in amounts and on terms and conditions
            acceptable to Bank in its good faith business judgment). Borrower
            shall execute all standard form applications and agreements of Bank
            in connection with the FX Forward Contracts, and without limiting
            any of the terms of such applications and agreements, Borrower shall
            pay all standard fees and charges of Bank in connection with the FX
            Forward Contracts. All amounts that Bank pays or expends in respect
            of any FX Forward Contracts shall constitute Obligations hereunder.

            As used herein, the term "Unfunded Availability" means, as of any
            date of determination, the amount, as determined by Bank in its good
            faith business judgment, equal to the aggregate Advances and other
            Credit Extensions available to the Borrower under the Loan Agreement
            (after deduction of all outstanding Advances and other Credit
            Extensions and all applicable reserves).

            determine in its good faith business judgment in connection with the
            Cash Management Services, and Bank may charge to Borrower's Loan
            account any amounts that may become due or owing to Bank in
            connection with the Cash Management Services. Borrower agrees to
            execute and deliver to Bank all standard form applications and
            agreements of Bank in connection with the Cash Management Services,
            and, without limiting any of the terms of such applications and

            in connection with the Cash Management Services. The Cash Management
            Services shall terminate upon the earlier of (a) the Revolving
            Maturity Date, or (b) any earlier effective date of termination of
            this Agreement (or such later date requested by Borrower as Bank may

            Borrower's Obligations in respect of the Cash Management Services
            are secured by cash in amounts and on terms and conditions
            acceptable to Bank in its sole discretion). Upon the occurrence and
            during the continuation of an Event of Default, Bank shall have the
            right to require the Obligations in respect of the Cash Management
            Services to be secured by cash in amounts and on terms and
            conditions acceptable to Bank in its good faith business judgment.

            Schedule, including the following: (a) reserves to reflect events,
            conditions, contingencies or risks which, as determined by Bank in
