1        ACCOUNTING AND OTHER TERMS

         Accounting terms not defined in this Agreement will be construed
following GAAP. Calculations and determinations must be made following GAAP. The
term "financial statements" includes the notes and schedules. The terms
"including" and "includes" always mean "including (or includes) without
limitation," in this or any Loan Document.

2        LOAN AND TERMS OF PAYMENT

2.1      PROMISE TO PAY.

         Borrower promises to pay Bank the unpaid principal amount of all Credit
Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1    REVOLVING ADVANCES.

(a) Bank will make Advances not exceeding the Credit Limit shown on Schedule 1
to the Agreement (the "Schedule"). Amounts borrowed under this Section may be
repaid and reborrowed during the term of this Agreement.

(b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by
12:00 p.m. Pacific time on the Business Day the Advance is to be made. Borrower
must promptly confirm the notification by delivering to Bank the Payment/Advance
Form attached as Exhibit B. Bank will credit Advances to Borrower's deposit
account. Bank may make Advances under this Agreement based on instructions from
a Responsible Officer or his or her designee or without instructions if the
Advances are necessary to meet Obligations which have become due. Bank may rely
on any telephone notice given by a person whom Bank believes is a Responsible
Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due
to such reliance.

(c) The Committed Revolving Line terminates on the Revolving Maturity Date, when
all Advances are immediately payable.

(d) Borrower shall have the right to terminate the Committed Revolving Line
prior to the Revolving Maturity Date, effective three Business Days after
written notice of termination is given to Bank, in which event Borrower shall
pay in full all Obligations on the effective date of termination. In the event
Borrower terminates the Committed Revolving Line prior to the Revolving Maturity
Date, or if the Committed Revolving Line is terminated by Bank prior to the
Revolving Maturity Date upon an Event of Default, Borrower shall pay Bank the
Termination Fee set forth in the Schedule.

2.1.2    LETTERS OF CREDIT SUBLIMIT.

         Bank will issue or have issued letters of credit (the "Letters of
Credit") for Borrower's account not exceeding the amount shown on the Schedule.
Each Letter of Credit will have an expiry date of no later than 180 days after
the Revolving Maturity Date, but Borrower's reimbursement obligation will 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 agrees to
execute any further documentation in connection with the Letters of Credit as
Bank may reasonably request.

2.1.3    [INTENTIONALLY OMITTED]

2.2      OVERADVANCES.

         If Borrower's Obligations under Section 2.1.1, 2.1.2 and 2.1.3 exceed
the lesser of either (i) the Committed Revolving Line or (ii) the Borrowing
Base, Borrower shall pay Bank the excess within three Business Days thereafter.

2.3      INTEREST RATE, PAYMENTS.

(a) Interest Rate. Advances accrue interest on the outstanding principal balance
at the interest rate set forth in the Schedule. After an Event of Default,
Obligations accrue interest at 5 percent above the rate effective immediately
before the Event of Default. The interest rate increases or decreases when the
Prime Rate changes. Interest is computed on a 360 day year for the actual number
of days elapsed.

(b) Payments. Interest due on the Committed Revolving Line is payable on the 6th
day of each month. Bank may debit any of Borrower's deposit accounts maintained
with Bank, including the Accounts shown on Schedule 2, for principal and
interest payments owing or any amounts Borrower owes Bank. Bank will promptly
notify Borrower when it debits Borrower's accounts. These debits are not a
set-off. Payments received after 12:00 noon Pacific time are considered received
at the opening of business on the next Business Day. When a payment is due on a
day that is not a Business Day, the payment is due the next Business Day and
additional fees or interest accrue.

2.4      FEES.

         Borrower will pay:

(a) Facility Fee. A fully earned, non-refundable Facility Fee in the amount
shown on the Schedule, which shall be due on the Closing Date; and

(b) Bank Expenses. All Bank Expenses (including reasonable attorneys' fees and
reasonable expenses) incurred through and after the date of this Agreement, are
payable when due.

3        CONDITIONS OF LOANS

3.1      CONDITIONS PRECEDENT TO INITIAL CREDIT EXTENSION.

         Bank's obligation to make the initial Credit Extension is subject to
the condition precedent that it receive the agreements, documents and fees it
requires.

3.2      CONDITIONS PRECEDENT TO ALL CREDIT EXTENSIONS.

         Bank's obligations to make each Credit Extension, including the initial
Credit Extension, is subject to the following:

(a) timely receipt of any Payment/Advance Form; and

(b) the representations and warranties in Section 5 must be true (subject to the
materiality provisions in Section 5) on the date of the Payment/Advance Form and
on the effective date of each Credit Extension and no Event of Default may have
occurred and be continuing, or result from the Credit

Extension. Each Credit Extension is Borrower's representation and warranty on
that date that the representations and warranties of Section 5 remain true.

4        CREATION OF SECURITY INTEREST

4.1      GRANT OF SECURITY INTEREST.

         Borrower grants Bank a continuing security interest in all presently
existing and later acquired Collateral to secure all Obligations and performance
of each of Borrower's duties under the Loan Documents. Except for Permitted
Liens, the Bank will, at all times, have a first-priority security interest in
all of the Collateral. Bank's lien and security interest in the Collateral will
continue until Borrower fully satisfies its Obligations, and all obligations of
the Bank to make Advances or otherwise extend credit accommodations have
terminated.

4.2      AUTHORIZATION TO FILE FINANCING STATEMENTS.

         Borrower authorizes Bank to file financing statements without notice to
Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in
order to perfect or protect Bank's interest in the Collateral.

5        REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants that the following statements are true
and correct on the date hereof and Borrower covenants that the following
statements will continue to be true and correct throughout the term of this
Agreement and so long as any Obligations are outstanding:

5.1      DUE ORGANIZATION AND AUTHORIZATION.

         Borrower and each of its Subsidiary is duly existing and in good
standing in its state of formation and qualified and licensed to do business in,
and in good standing in, any state in which the conduct of its business or its
ownership of property requires that it be qualified, except where the failure to
do so could not reasonably be expected to cause a Material Adverse Change.
Borrower has not changed its state of formation or its organizational structure
or type or any organizational number (if any) assigned by its jurisdiction of
formation.

         The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's formation documents, nor
constitute an event of default under any material agreement by which Borrower is
bound. Borrower is not in default under any agreement to which it is a party or
by which it is bound in which the default could reasonably be expected to cause
a Material Adverse Change.

5.2      COLLATERAL.

         Borrower has good title to the Collateral, free of Liens except
Permitted Liens. Borrower has no other deposit account, other than the deposit
accounts described in the Representations or Schedule 2. Each Account with
respect to which Advances are requested by Borrower shall, on the date each
Advance is requested and made, represent an undisputed bona fide existing
unconditional obligation of the account debtor created by the sale, delivery,
and acceptance of goods or the rendition of services in the ordinary course of
Borrower's business. The Collateral is not in the possession of any third party
bailee (such as at a warehouse), except for Collateral consisting of Inventory
located at the following warehouse in Memphis, Tennessee: 4638 E. Shelby Drive,
Memphis, Tennessee 38118 (the "Tennessee Warehouse"). Borrower shall cause the
Tennessee Warehouse to execute and deliver to Bank an agreement pursuant to
which the Tennessee Warehouse waives any liens on the Collateral stored with it
and acknowledges that it is holding such Collateral for the benefit of Bank in
form acceptable to the Bank. In the event that Borrower, after the date hereof,
intends to store or otherwise deliver the Collateral to such a bailee, then
Borrower will receive the prior written consent of Bank and such bailee must
acknowledge in writing that the bailee waives any liens on the Collateral and
acknowledges that the bailee is holding such Collateral for the benefit of Bank
in form acceptable to the Bank. Borrower has no notice of any actual or imminent
Insolvency Proceeding of any account debtor whose accounts are an

                                      -3-

<PAGE>

Eligible Account in any Borrowing Base Certificate. All Inventory is in all
material respects of good and marketable quality, free from material defects.
Borrower is the sole owner of the Intellectual Property, except for licenses
granted to its customers in the ordinary course of business and permitted under
this Agreement. Each Patent is, to the best of Borrower's knowledge, valid and
enforceable and no part of the Intellectual Property has been judged invalid or
unenforceable, in whole or in part, and no claim has been made that any part of
the Intellectual Property violates the rights of any third party, except to the
extent such claim could not reasonably be expected to cause a Material Adverse
Change.

5.3      LITIGATION.

         Except as shown in the Schedule, there are no actions or proceedings
pending or, to the knowledge of Borrower's 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.

5.4      NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS.

         All consolidated financial statements for Borrower, and any Subsidiary,
delivered to Bank fairly present in all material respects Borrower's
consolidated financial condition and Borrower's consolidated results of
operations. There has not been any material deterioration in Borrower's
consolidated financial condition since the date of the most recent financial
statements submitted to Bank.

5.5      REGULATORY COMPLIANCE.

         Borrower is not an "investment company" or a company "controlled" by an
"investment company" under the Investment Company Act. Borrower is not engaged
as one of its important activities in extending credit for margin stock (under
Regulations T and U of the Federal Reserve Board of Governors). Borrower has
complied in all material respects with the Federal Fair Labor Standards Act.
Borrower has not violated any laws, ordinances or rules, the violation of which
could reasonably be expected to cause a Material Adverse Change. None of
Borrower's or any Subsidiary's properties or assets has been used by Borrower or
any Subsidiary or, to the best of Borrower's knowledge, by previous Persons, in
disposing, producing, storing, treating, or transporting any hazardous substance
other than legally. Borrower and each Subsidiary has timely filed all required
tax returns and paid, or made adequate provision to pay, all material taxes,
except those being contested in good faith with adequate reserves under GAAP and
which do not result in any tax lien on any of the Collateral. Borrower and each
Subsidiary has obtained all consents, approvals and authorizations of, made all
declarations or filings with, and given all notices to, all government
authorities that are necessary to continue its business as currently conducted,
except where the failure to do so could not reasonably be expected to cause a
Material Adverse Change.

5.6      SUBSIDIARIES.

         Borrower does not own any stock, partnership interest or other equity
securities except for Permitted Investments.

5.7      REPRESENTATIONS; FULL DISCLOSURE.

         The information in the Representations previously submitted to Bank
continues to be true and correct as of the date hereof. No written
representation, warranty or other statement of Borrower in any certificate or
written statement given to Bank (taken together with all such written
certificates and written statements to Bank) contains any untrue statement of a
material fact or omits to state a material fact necessary to make the statements
contained in the certificates or statements not misleading.

6        AFFIRMATIVE COVENANTS

obligation to lend, or there are outstanding Obligations (unless otherwise
specified below):

6.1      GOVERNMENT COMPLIANCE.

         Borrower will maintain its and all Subsidiaries' legal existence and
good standing in its jurisdiction of formation and maintain qualification in
each jurisdiction in which the failure to so qualify would reasonably be
expected to cause a material adverse effect on Borrower's business or
operations. Borrower will comply, and have each Subsidiary comply, with all
laws, ordinances and regulations to which it is subject, noncompliance with
which could have a material adverse effect on Borrower's business or operations
or would reasonably be expected to cause a Material Adverse Change.

6.2      FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.

(a) Borrower will deliver to Bank:

                  (i)      as soon as available, but no later than 30 days after
                           the last day of each month, a company prepared
                           consolidated balance sheet and income statement
                           covering Borrower's consolidated operations during
                           the period certified by a Responsible Officer and in
                           a form acceptable to Bank;

                  (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.

                           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.

                  (iv)     Within 20 days after the last day of each month,
                           Borrower will deliver to Bank an aged listings of
                           Borrower's Accounts and accounts payable, aged by

                           check register (if any).

                  (v)      Within 30 days after the last day of each month,
                           Borrower will deliver to Bank with the monthly

                           GAAP, consistently applied, together with an
                           unqualified opinion on the financial

                           any copyright, patent or trademark not shown in any
                           intellectual property security agreement between
                           Borrower and Bank or knowledge of an event that
                           materially adversely affects the value of the
                           Intellectual Property.

                  (x)      a prompt report of any legal actions pending or
                           threatened against Borrower or any Subsidiary that
                           could 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;

                  under the following clauses above need not be provided with
                  respect to such month: 6.2(a)(i), (ii), (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.

(b) Allow Bank to audit Borrower's Collateral at Borrower's expense, provided
that such expenses shall not exceed $600 per person per day, plus reasonable out

         Borrower will keep all Inventory in good and marketable condition, free

         Borrower will make, and cause each Subsidiary to make, timely payment

and which do not result in any tax lien on any of the Collateral) and will
deliver to Bank, on demand, appropriate certificates attesting to the payment.

6.5      INSURANCE.

         Borrower will keep its business and the Collateral insured for risks
and in amounts, as Bank may reasonably request. Insurance policies will be in a
form, with companies, and in amounts that are satisfactory to Bank in Bank's
reasonable discretion. All property policies will have a lender's loss payable
endorsement showing Bank as an additional loss payee and all liability policies
will show the Bank as an additional insured and provide that the insurer must
give Bank at least 20 days notice before canceling its policy. At Bank's
request, Borrower will deliver certified copies of policies and evidence of all
premium payments. Proceeds payable under any policy will, at Bank's option, be
payable to Bank on account of the Obligations.

account. 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 Bank in Borrower's operating account at Bank.
Borrower agrees that it will not commingle payments and proceeds of Accounts and
other Collateral with any of Borrower's other funds or property, but will hold
such payments and proceeds separate and apart from such other funds and property
and in an express trust for Bank. Nothing in this Section limits the
restrictions on Transfers of Collateral set forth elsewhere in this Agreement.

6.10     FURTHER ASSURANCES.

as Bank reasonably requests to perfect or continue Bank's security interest in
the Collateral or to effect the purposes of this Agreement.

7        NEGATIVE COVENANTS

         Borrower will not do any of the following without Bank's prior written

obligation to lend and there are any outstanding Obligations:

7.1      DISPOSITIONS.

         Convey, sell, lease, transfer or otherwise dispose of (collectively

Intellectual Property and similar arrangements for the use of the property of
Borrower or its Subsidiaries in the ordinary course of business; (iii) of

         Engage in or permit any of its Subsidiaries to engage in any business

thereto, or enter into any transaction outside the ordinary course of business,
or any person or group of related persons shall acquire more than 50% of the
outstanding shares of stock of Borrower, in one or more transactions. Borrower

convey any right to receive income, including the sale of any Accounts, or

transaction with a nonaffiliated Person.

7.8      SUBORDINATED DEBT.

         Make or permit any payment on any Subordinated Debt, except under the

9        BANK'S RIGHTS AND REMEDIES

9.1      RIGHTS AND REMEDIES.

         When an Event of Default occurs and continues Bank may, without notice
or demand, do any or all of the following:

(a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.6 occurs all Obligations are immediately due and
payable without any action by Bank);

(b) Stop advancing money or extending credit for Borrower's benefit under this
Agreement or under any other agreement between Borrower and Bank and terminate
the Committed Revolving Line;

(c) Settle or adjust disputes and claims directly with account debtors for
amounts, on terms and in any order that Bank considers advisable;

(d) Make any payments and do any acts it considers necessary or reasonable to
protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates. Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred. Borrower grants Bank a license to enter and occupy any of its
premises, without charge, to exercise any of Bank's rights or remedies;

(e) Apply to the Obligations any (i) balances and deposits of Borrower it holds,
or (ii) any amount held by Bank owing to or for the credit or the account of
Borrower;

(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale,
advertise for sale, and sell the Collateral. Bank is granted a non-exclusive,
royalty-free license or other right to use, without charge, Borrower's labels,
Intellectual Property, and advertising matter, and any similar property as it
pertains to the Collateral, in completing production of, advertising for sale,
and selling any Collateral and, in connection with Bank's exercise of its rights
under this Section, Borrower's rights under all licenses and all franchise
agreements inure to Bank's benefit; and

(g) Dispose of the Collateral according to the Code.

9.2      POWER OF ATTORNEY.

         Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits. Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred. Bank's
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
are coupled with an interest, are irrevocable until all Obligations have been
fully repaid and performed and Bank's obligation to provide Credit Extensions
terminates.

                                      -10-

<PAGE>

9.3      ACCOUNTS COLLECTION.

         When an Event of Default occurs and continues, Bank may notify any
Person owing Borrower money of Bank's security interest in the funds and demand
payment of, and collect any Accounts, general intangibles and other Collateral,
and, in connection therewith, Borrower irrevocably authorizes Bank to endorse or
sign Borrower's name on all collections, receipts, instruments and other
documents, and, in Bank's good faith business judgment, to grant extensions of
time to pay, compromise claims and settle Accounts and general intangibles for
less than face value. When an Event of Default occurs and continues, Borrower
shall collect all payments in trust for Bank and, if requested by Bank,
immediately deliver the payments to Bank in the form received from the account
debtor, with proper endorsements for deposit.

9.4      BANK EXPENSES.

If Borrower fails to obtain the insurance called for by Section 6.5 or fails to
pay any premium thereon or fails to pay any other amount, which Borrower is
obligated to pay under this Agreement or any other Loan Document, Bank may
obtain such insurance or make such payment, and all amounts so paid by Bank are
Bank Expenses and immediately due and payable, bearing interest at the then
applicable rate and secured by the Collateral. No payments by Bank shall be
deemed an agreement to make similar payments in the future or Bank's waiver of
any Event of Default.

9.5      BANK'S LIABILITY FOR COLLATERAL.

         If Bank complies with reasonable banking practices and Section 9207 of
the Code, it is not liable for: (a) the safekeeping of the Collateral; (b) any
loss or damage to the Collateral; (c) any diminution in the value of the
Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or
other person. Borrower bears all risk of loss, damage or destruction of the
Collateral.

9.6      REMEDIES CUMULATIVE.

         Bank's rights and remedies under this Agreement, the Loan Documents,
and all other agreements are cumulative. Bank has all rights and remedies
provided under the Code, by law, or in equity. Bank's exercise of one right or
remedy is not an election, and Bank's waiver of any Event of Default is not a
continuing waiver. Bank's delay is not a waiver, election, or acquiescence. No
waiver is effective unless signed by Bank and then is only effective for the
specific instance and purpose for which it was given.

9.7      DEMAND WAIVER.

         Borrower waives demand, notice of default or dishonor, notice of
payment and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

9.8      ASSET BASED TERMS.

         Without limiting Bank's other rights and remedies, if an Event of
Default occurs and is continuing, the provisions of Exhibit E hereto (the "Asset
Based Terms") shall be effective, upon written notice by Bank to the Borrower.

10       NOTICES

         All notices or demands by any party about this Agreement or any other
related agreement must be in writing and be personally delivered or sent by an
overnight delivery service, by certified mail, postage prepaid, return receipt
requested, or by fax to the addresses set forth at the beginning of this
Agreement and, in the case of notices by fax, to the latest fax number a party

limitations for actions that may be brought against Bank have run.

12.8     CONFIDENTIALITY.

         In handling any confidential information, Bank will exercise the same
degree of care that it exercises for its own proprietary information, but
disclosure of information may be made (i) to Bank's subsidiaries or affiliates
in connection with their business with Borrower, (ii) to prospective transferees
or purchasers of any interest in the loans (provided, however, Bank shall use

The following are the "Asset Based Terms":

         (1) SCHEDULES AND DOCUMENTS RELATING TO ACCOUNTS. Borrower shall
deliver to Bank transaction reports, Advance requests, schedules of 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 furnish Bank with copies (or, at Bank's
request, originals) of all contracts, orders, invoices, and other similar
documents, and all shipping instructions, delivery 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
foregoing. 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 shall deliver to Bank the originals of all instruments, 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.

         (2) NOTIFICATION. Bank or its designee may, at any time, notify Account
Debtors that it has a security interest in the Accounts and that payment on the
Accounts is to be made directly to the Bank.

         (3) LOAN REQUESTS. Without limiting the right of Bank to cease making
Advances on an Event of Default, requests for Advances shall be in writing and
shall be accompanied by a current Transaction Report on Bank's standard form.

         (4) RESERVES. Without limiting the right of Bank to cease making
Advances on an Event of Default, Bank shall have the right, from time to time,
to establish and deduct the following reserves from the amount of Advances,
Letters of Credit and other financial accommodations under the lending
formula(s) provided in the Schedule: (a) reserves to reflect events, conditions,
contingencies or risks which, as determined by Bank in good faith, do or may
affect adversely (i) the Collateral or any other property which is security for
the Obligations or its value (including without limitation any increase in
delinquencies of Accounts), (ii) the assets, business or prospects of Borrower,
or (iii) the security interests and other rights of Bank in the Collateral
(including the enforceability, perfection and priority thereof); and (b)
reserves to reflect Bank's good faith belief that any collateral report or
financial information furnished by or on behalf of Borrower to Bank is or may
have been incomplete, inaccurate or misleading in any material respect.

shall be modified as follows: the cure period in Section 8.3 of the Loan

                             limited to a total of $5,000,000 unless Borrower
                             converts to the Asset Based Terms, in accordance

<PAGE>

                             (b) while the Asset Based Terms are in effect:

                                    (1)      the Inventory Sublimit shall be
                                             $2,000,000,

                                    (2)      the Inventory Percentage Limit
                                             shall be 20%, and

                                    (3)      the Inventory Advance Rate may be
                                             reduced to such amount as Bank
                                             shall determine in its good faith
                                             business judgment, until Bank
                                             receives an appraisal of the forced
                                             liquidation value of the Inventory
                                             acceptable to Bank. Based on said
                                             appraisal, Bank may adjust the
                                             Inventory Advance Rate to such
                                             amount as it shall determine in its
                                             good faith business judgment.

                                    In the event the Asset Based Terms go into
                                    effect because of a breach of one of the
                                    financial covenants set forth in Section
                                    5.1(a) or (b) below, and as a result of the
                                    reduction in the Inventory Sublimit or the
                                    Inventory Percentage Limit under Section 1.2
                                    (b) (1) or (2) above the outstanding
                                    Advances with respect to Inventory exceed
                                    the limit set forth in Section 1.1(b) above,
                                    then Borrower shall have 15 days from the
                                    date the Asset Based Terms go into effect to
                                    repay such excess to Bank.

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

LETTER OF CREDIT SUBLIMIT
(SECTION 2.1.2):           $1,000,000

                           Bank will issue or have issued Letters of Credit for
                           Borrower's account not exceeding (i) the lesser of
                           the Committed Revolving Line or the Borrowing Base,
                           minus (ii) the outstanding principal balance of the
                           Advances; however, the face amount of outstanding
                           Letters of Credit (including drawn but unreimbursed
                           Letters of Credit) may not exceed the Letter of
                           Credit Sublimit set forth above.

    INTEREST RATE
    (Section 2.3(a)):      A rate equal to the "Prime Rate" in effect from time
                           to time, plus 0.50% per annum, provided that:

                           (i)      in the event the Borrower has a fiscal
                                    quarter ending after the date hereof in
                                    which its EBITDA is equal to or greater than
                                    zero, then the interest rate shall be
                                    reduced to the Prime Rate, provided that if,
                                    in a subsequent fiscal quarter EBITDA is
                                    less than zero, then the interest rate shall
                                    return to the Prime Rate plus 0.50% per
                                    annum; and

                           (ii)     while the Asset Based Terms are in effect,
                                    the interest rate shall be a rate equal to
                                    the Prime Rate plus 1.25% per annum, except
                                    that (A) in the event the Borrower has a
                                    fiscal quarter ending after the date hereof
                                    in which its EBITDA is equal to or greater
                                    than zero, then the interest rate while the
                                    Asset Based Terms are in effect shall be
                                    equal to the Prime Rate plus 0.75% per
                                    annum, and (B) if, in a subsequent fiscal
                                    quarter EBITDA is less than zero, then the
                                    interest rate shall return to the Prime Rate
                                    plus 1.25% per annum

                           EBITDA is defined in Section 5.3 below. Changes in
                           the interest rate based on EBITDA as provided above
                           shall go into effect following Bank's review and
                           approval of Borrower's financial statements showing
                           Borrower's EBITDA will result in the interest rate
                           change.

    Fee:                   During each month or portion thereof that the Asset

                    INTELLECTUAL PROPERTY SECURITY AGREEMENT

         This Intellectual Property Security Agreement is entered into as of
September 27, 2002 by and between SILICON VALLEY BANK ("Bank") and MOBILITY
ELECTRONICS, INC. ("Grantor").

                                    RECITALS

         A. Bank has agreed to make certain advances of money and to extend
certain financial accommodation to Grantor (the "Loans") in the amounts and
manner set forth in that certain Loan and Security Agreement by and between Bank
and Grantor dated of even date herewith (as the same may be amended, modified or
supplemented from time to time, the "Loan Agreement"; capitalized terms used
herein are used as defined in the Loan Agreement). Bank is willing to make the
Loans to Grantor, but only upon the condition, among others, that Grantor shall
grant to Bank a security interest in certain Copyrights, Trademarks, Patents,
and Mask Works to secure the obligations of Grantor under the Loan Agreement.

         B. Pursuant to the terms of the Loan Agreement, Grantor has granted to
Bank a security interest in all of Grantor's right, title and interest, whether
presently existing or hereafter acquired, in, to and under all of the
Collateral.

         NOW, THEREFORE, for good and valuable consideration, receipt of which
is hereby acknowledged, and intending to be legally bound, as collateral
security for the prompt and complete payment when due of its obligations under
the Loan Agreement, Grantor hereby represents, warrants, covenants and agrees as
follows:

                                    AGREEMENT

         To secure its obligations under the Loan Agreement, Grantor grants and
pledges to Bank a security interest in all of Grantor's right, title and
interest in, to and under its Intellectual Property Collateral (including
without limitation those Copyrights, Patents, Trademarks and Mask Works listed
on Exhibits A, B, C, and D hereto), and including without limitation all
proceeds thereof (such as, by way of example but not by way of limitation,
license royalties and proceeds of infringement suits), the right to sue for
past, present and future infringements, all rights corresponding thereto
throughout the world and all re-issues, divisions continuations, renewals,
extensions and continuations-in-part thereof.

         This security interest is granted in conjunction with the security
interest granted to Bank under the Loan Agreement. The rights and remedies of
Bank with respect to the security interest granted hereby are in addition to
those set forth in the Loan Agreement and the other Loan Documents, and those
which are now or hereafter available to Bank as a matter of law or equity. Each
right, power and remedy of Bank provided for herein or in the Loan Agreement or
any of the Loan Documents, or now or hereafter existing at law or in equity
shall be cumulative and concurrent and shall be in addition to every right,
power or remedy provided for herein and the exercise by Bank of any one or more
of the rights, powers or remedies provided for in this Intellectual Property
Security Agreement, the Loan Agreement or any of the other Loan Documents, or
now or hereafter existing at law or in equity, shall not preclude the
simultaneous or later exercise by any person, including Bank, of any or all
other rights, powers or remedies.
