         2    LOAN AND TERMS OF PAYMENT

         2.1 Promise to Pay. Borrower hereby unconditionally promises to pay
Bank the outstanding principal amount of all Credit Extensions and accrued and
unpaid interest thereon as and when due in accordance with this Agreement.

         2.1.1    Revolving Advances.

                  (a) Availability. Subject to the terms and conditions of this
Agreement, Bank shall make Advances not exceeding the Availability Amount.
Amounts borrowed under the Revolving Line may be repaid and, prior to the
Revolving Line Maturity Date, reborrowed, subject to the applicable terms and
conditions precedent herein.

                  (b) Termination; Repayment. The Revolving Line terminates on
the Revolving Line Maturity Date, when the principal amount of all Advances,
the unpaid interest thereon, and all other Obligations relating to the Revolving
Line shall be immediately due and payable.

         2.1.2    Letters of Credit Sublimit.

                  (a) As part of the Revolving Line, Bank shall issue or have
issued Letters of Credit for Borrower's account. The face amount of outstanding
Letters of Credit (including drawn but unreimbursed Letters of Credit and any
Letter of Credit Reserve) may not exceed $10,000,000, subject to the Overall
Sublimit. Such aggregate amounts utilized hereunder shall at all times reduce
the amount otherwise available for Advances under the Revolving Line. If, on the
Revolving Maturity Date, there are any outstanding Letters of Credit, then on
such date Borrower shall provide to Bank cash collateral in an amount equal to
105% of the face amount of all such Letters of Credit plus all interest, fees,
and costs due or to become due in connection therewith (as estimated by Bank in
its good faith business judgment), to secure all of the Obligations relating to
said Letters of Credit. All Letters of Credit shall be in form and substance
acceptable to Bank in its sole discretion and shall be subject to the terms and
conditions of Bank's standard Application and Letter of Credit Agreement (the
"Letter of Credit Application"). Borrower agrees to execute any further
documentation in connection with the Letters of Credit as Bank may reasonably
request.


<page>


          (b) The obligation of Borrower to immediately reimburse Bank for
drawings made under Letters of Credit shall be absolute, unconditional, and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement, such Letters of Credit, and the Letter of Credit Application.

          (c) Borrower may request that Bank issue a Letter of Credit payable
in a Foreign Currency. If a demand for payment is made under any such Letter of
Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent
of the amount thereof (plus fees and charges in connection therewith such as
wire, cable, SWIFT or similar charges) in Dollars at the then-prevailing rate of
exchange in San Francisco, California, for sales of the Foreign Currency for
transfer to the country issuing such Foreign Currency.

          (d) To guard against fluctuations in currency exchange rates, upon the
issuance of any Letter of Credit payable in a Foreign Currency, Bank shall
create a reserve (the "Letter of Credit Reserve") under the Revolving Line in an
amount equal to ten percent (10%) of the face amount of such Letter of Credit.
The amount of the Letter of Credit Reserve may be adjusted by Bank from time to
time to account for fluctuations in the exchange rate. The availability of funds
under the Revolving Line shall be reduced by the amount of such Letter of Credit
Reserve for as long as such Letter of Credit remains outstanding.

     2.1.3 Foreign Exchange Sublimit. As part of the Revolving Line, Borrower
may enter into foreign exchange contracts with Bank under which Borrower commits
to purchase from or sell to Bank a specific amount of Foreign Currency (each, a
"FX Forward Contract") on a specified date (the "Settlement Date"). FX Forward
Contracts shall have a Settlement Date of at least one (1) FX Business Day after
the contract date and shall be subject to a reserve of ten percent (10%) of each
outstanding FX Forward Contract in a maximum aggregate amount equal to
$10,000,000 (the "FX Reserve"), subject to the Overall Sublimit. The aggregate
amount of FX Forward Contracts at any one time may not exceed ten (10) times the
amount of the FX Reserve.

     2.1.4 Cash Management Services Sublimit. Borrower may use up to $10,000,000
(the "Cash Management Services Sublimit") of the Revolving Line, subject to the
Overall Sublimit for Bank's cash management services which may include merchant
services, direct deposit of payroll, business credit card, and check cashing
services identified in Bank's various cash management services agreements
(collectively, the "Cash Management Services"). Any amounts Bank pays on behalf
of Borrower or any amounts that are not paid by Borrower for any Cash Management
Services will be treated as Advances under the Revolving Line and will accrue
interest at the interest rate applicable to Advances.

     2.2 Overadvances. If, at any time, the Credit Extensions under Sections
2.1.1, 2.1.2, 2.1.3 and 2.1.4 exceed the lesser of either (a) the Revolving
Line or (b) the Borrowing Base, Borrower shall immediately pay to Bank in cash
such excess

     2.3 General Provisions Relating to the Advances. Each Advance shall, at
Borrower's option in accordance with the terms of this Agreement, be either in
the form of a Prime Rate Advance or a LIBOR Advance; provided that in no event
shall Borrower maintain at any time LIBOR Advances having more than two (2)
different Interest Periods. Borrower shall pay interest accrued on the Advances
at the rates and in the manner set forth in Section 2.4.

     2.4  Payment of Interest on the Credit Extensions.

          (a) Computation of Interest. Interest on the Credit Extensions
and all fees payable hereunder shall be computed on the basis of a 360-day year
and the actual number of days elapsed in the period during which such interest
accrues. In computing interest on any Credit Extension, the date of the making
of such Credit Extension shall be included and the date of payment shall be
excluded; provided, however, that if any Credit Extension is repaid on the same
day on which it is made, such day shall be included in computing interest on
such Credit Extension.

           (b) Advances. Each Advance shall bear interest on the
outstanding principal amount thereof from the date when made, continued or
converted until paid in full at a rate per annum equal to the Prime Rate plus
the Prime Rate Margin or the LIBOR Rate plus the LIBOR Rate Margin, as the case
may be. On and after the expiration of any Interest Period applicable to any
LIBOR Advance outstanding on the date of occurrence of an Event of Default or
acceleration of the Obligations, the Effective Amount of such LIBOR Advance
shall, during the continuance of such Event of Default or after acceleration,
bear interest at a rate per annum equal to the Prime Rate plus six percentage
points (6.00%). Pursuant to the terms hereof, interest on each Advance shall be
paid in arrears on each Interest Payment Date. Interest shall also be paid on
the date of any prepayment of any Advance pursuant to this Agreement for the
portion of any Advance so prepaid and upon payment (including prepayment) in
full thereof. All accrued but unpaid interest on the Advances shall be due and
payable on the Revolving Line Maturity Date.


<page>


          (c) Default Interest. Except as otherwise provided in Section
2.4(b), after an Event of Default, Obligations shall bear interest five
percentage points (5.00%) above the rate effective immediately before the Event
of Default (the "Default Rate"). Payment or acceptance of the increased interest
provided in this Section 2.4(c) is not a permitted alternative to timely payment
and shall not constitute a waiver of any Event of Default or otherwise prejudice
or limit any rights or remedies of Bank.

          (d) Prime Rate Advances. Each change in the interest rate of
the Prime Rate Advances based on changes in the Prime Rate shall be effective on
the effective date of such change and to the extent of such change. Bank shall
use its best efforts to give Borrower prompt notice of any such change in the
Prime Rate; provided, however, that any failure by Bank to provide Borrower with
notice hereunder shall not affect Bank's right to make changes in the interest
rate of the Prime Rate Advances based on changes in the Prime Rate.

          (e) LIBOR Advances. The interest rate applicable to each LIBOR
Advance shall be determined in accordance with Section 3.6(a) hereunder. Subject
to Sections 3.6 and 3.7, such rate shall apply during the entire Interest Period
applicable to such LIBOR Advance, and interest calculated thereon shall be
payable on the Interest Payment Date applicable to such LIBOR Advance.

          (f) Debit of Accounts. Bank may debit any of Borrower's
deposit accounts, including the Designated Deposit Account, for principal and
interest payments when due, or any other amounts Borrower owes Bank, when due.
Bank shall promptly notify Borrower after it debits Borrower's accounts. These
debits shall not constitute a set-off.

     2.5  Fees.  Borrower shall pay to Bank:

          (a) Renewal and Amendment Fee. A fully earned, non-refundable
renewable and amendment fee of $70,000, on the Effective Date; and

          (b) Letter of Credit Fee. Bank's customary fees and expenses for the
issuance or renewal of Letters of Credit upon the issuance, each anniversary of
the issuance, and the renewal of such Letter of Credit; and

          (c) Bank Expenses. All Bank Expenses (including reasonable attorneys'
fees and expenses, plus expenses, for documentation and negotiation of this
Agreement) incurred through and after the Effective Date, 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

          (e) Borrower shall have delivered an update letter to the Perfection
Certificate(s) previously delivered to Bank;

     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 a Notice of Borrowing;

          (b) the representations and warranties in Section 5 shall be
true in all material respects on the date of the Notice of Borrowing and on the
effective date of each Credit Extension; provided, however, that such
materiality qualifier shall not be applicable to any representations and
warranties that already are qualified or modified by materiality in the text
thereof; and provided, further that those representations and warranties
expressly referring to a specific date shall be true, accurate and complete in
all material respects as of such date, and no Event of Default shall have

     3.3      Covenant to Deliver.

     Borrower agrees to deliver to Bank each item required to be delivered
to Bank under this Agreement as a condition to any Credit Extension. Borrower
expressly agrees that the extension of a Credit Extension prior to the receipt
by Bank of any such item shall not constitute a waiver by Bank of Borrower's
obligation to deliver such item, and any such extension in the absence of a
required item shall be in Bank's sole discretion.

     3.4      Procedure for the Borrowing of Advances.

          (a) Subject to the prior satisfaction of all other applicable
conditions to the making of an Advance set forth in this Agreement, each Advance
shall be made upon Borrower's irrevocable written notice delivered to Bank in
the form of a Notice of Borrowing, each executed by a Responsible Officer of
Borrower 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. Such Notice of Borrowing must be received by Bank prior to 11:00 a.m.
Pacific time, (i) at least three (3) Business Days prior to the requested
Funding Date, in the case of LIBOR Advances, and (ii) at least one (1) Business
Day prior to the requested Funding Date, in the case of Prime Rate Advances,
specifying:

               (1) the amount of the Advance, which, if a LIBOR Advance is
requested, shall be in an aggregate minimum principal amount of $1,000,000 or
in any integral multiple of $1,000,000 in excess thereof;

               (2) the requested Funding Date;

               (3) whether the Advance is to be comprised of LIBOR
Advances or Prime Rate Advances; and

               (4) the duration of the Interest Period applicable to any such
LIBOR Advances included in such notice; provided that if the Notice of Borrowing
shall fail to specify the duration of the Interest Period for any Advance
comprised of LIBOR Advances, such Interest Period shall be one (1) month.

                  (b) The proceeds of all such Advances will then be made
available to Borrower on the Funding Date by Bank by transfer to the Designated
Deposit Account and, subsequently, by wire transfer to such other account as
Borrower may instruct in the Notice of Borrowing. No Advances shall be deemed
made to Borrower, and no interest shall accrue on any such Advance, until the
related funds have been deposited in the Designated Deposit Account.

     3.5  Conversion and Continuation Elections.

          (a) So long as (i) no Event of Default or Default exists; (ii)
Borrower shall not have sent any notice of termination of this Agreement; and
(iii) Borrower shall have complied with such customary procedures as Bank has
established from time to time for Borrower's requests for LIBOR Advances,
Borrower may, upon irrevocable written notice to Bank:

               (1) elect to convert on any Business Day, Prime Rate Advances in
an amount equal to $1,000,000 or any integral multiple of $1,000,000 in excess
thereof into LIBOR Advances;

               (2) elect to continue on any Interest Payment Date any LIBOR
Advances maturing on such Interest Payment Date (or any part thereof in an
amount equal to $1,000,000 or any integral multiple of $1,000,000 in excess
thereof); provided, that if the aggregate amount of LIBOR Advances shall have
been reduced, by payment, prepayment, or conversion of part thereof, to be less
than $1,000,000, such LIBOR Advances shall automatically convert into Prime Rate
Advances, and on and after such date the right of Borrower to continue such
Advances as, and convert such Advances into, LIBOR Advances shall terminate; or

               (3) elect to convert on any Interest Payment Date any LIBOR
Advances maturing on such Interest Payment Date (or any part thereof in an
amount equal to $1,000,000 or any integral multiple of $1,000,000 in excess
thereof) into Prime Rate Advances.

          (b) Borrower shall deliver a Notice of Conversion/Continuation
in accordance with Section 10 to be received by Bank prior to 11:00 a.m. Pacific
time at least (i) three (3) Business Days in advance of the Conversion Date or
Continuation Date, if any Advances are to be converted into or continued as
LIBOR Advances; and (ii) one (1) Business Day in advance of the Conversion Date,
if any Advances are to be converted into Prime Rate Advances, in each case
specifying the:

               (1) proposed Conversion Date or Continuation Date;

               (2) aggregate amount of the Advances to be converted or
continued which, if any Advances are to be converted into or continued as LIBOR
Advances, shall be in an aggregate minimum principal amount of $1,000,000 or in
any integral multiple of $1,000,000 in excess thereof;

               (3) nature of the proposed conversion or continuation; and

               (4) duration of the requested Interest Period.

          (c) If upon the expiration of any Interest Period applicable
to any LIBOR Advances, Borrower shall have timely failed to select a new
Interest Period to be applicable to such LIBOR Advances, Borrower shall be
deemed to have elected to convert such LIBOR Advances into Prime Rate Advances.

          (d) Any LIBOR Advances shall, at Bank's option, convert into
Prime Rate Advances in the event that (i) an Event of Default or Default shall
exist, or (ii) the aggregate principal amount of the Prime Rate Advances which
have been previously converted to LIBOR Advances, or the aggregate principal
amount of existing LIBOR Advances continued, as the case may be, at the
beginning of an Interest Period shall at any time during such Interest Period
exceed the Revolving Line. Borrower agrees to pay Bank, upon demand by Bank (or
Bank may, at its option, charge the Designated Deposit Account or any other
account Borrower maintains with Bank) any amounts required to compensate Bank
for any loss (including loss of anticipated profits), cost, or expense incurred
by Bank, as a result of the conversion of LIBOR Advances to Prime Rate Advances
pursuant to any of the foregoing.

          (e) Notwithstanding anything to the contrary contained herein,
Bank shall not be required to purchase United States Dollar deposits in the
London interbank market or other applicable LIBOR market to fund any LIBOR
Advances, but the provisions hereof shall be deemed to apply as if Bank had
purchased such deposits to fund the LIBOR Advances.

     3.6      Special Provisions Governing LIBOR Advances.


     Notwithstanding any other provision of this Agreement to the contrary,
the following provisions shall govern with respect to LIBOR Advances as to the
matters covered:

          (a) Determination of Applicable Interest Rate. As soon as practicable
on each Interest Rate Determination Date, Bank shall determine (which
determination shall, absent manifest error in calculation, be final, conclusive
and binding upon all parties) the interest rate that shall apply to the LIBOR
Advances for which an interest rate is then being determined for the applicable
Interest Period and shall promptly give notice thereof (in writing or by
telephone confirmed in writing) to Borrower.

          (b) Inability to Determine Applicable Interest Rate. In the event that
Bank shall have determined (which determination shall be final and conclusive
and binding upon all parties hereto), on any Interest Rate Determination Date
with respect to any LIBOR Advance, that by reason of circumstances affecting the
London interbank market adequate and fair means do not exist for ascertaining
the interest rate applicable to such Advance on the basis provided for in the
definition of LIBOR, Bank shall on such date give notice (by facsimile or by
telephone confirmed in writing) to Borrower of such determination, whereupon (i)
no Advances may be made as, or converted to, LIBOR Advances until such time as
Bank notifies Borrower that the circumstances giving rise to such notice no
longer exist, and (ii) any Notice of Borrowing or Notice of
Conversion/Continuation given by Borrower with respect to Advances in respect of
which such determination was made shall be deemed to be rescinded by Borrower.

          (c) Compensation for Breakage or Non-Commencement of Interest Periods
Borrower shall compensate Bank, upon written request by Bank (which request
shall set forth the manner and method of computing such compensation), for all
reasonable losses, expenses and liabilities, if any (including any interest
paid by Bank to lenders of funds borrowed by it to make or carry its LIBOR
Advances and any loss, expense or liability incurred by Bank in connection with
the liquidation or re-employment of such funds) such that Bank may incur: (i) if
for any reason (other than a default by Bank or due to any failure of Bank to
fund LIBOR Advances due to impracticability or illegality hereunder) a borrowing
or a conversion to or continuation of any LIBOR Advance does not occur on a date
specified in a Notice of Borrowing or a Notice of Conversion/Continuation, as
the case may be, or (ii) if any principal payment or any conversion of any of
its LIBOR Advances occurs on a date prior to the last day of an Interest Period
applicable to that Advance.

          (d) Assumptions Concerning Funding of LIBOR Advances. Calculation of
all amounts payable to Bank hereunder shall be made as though Bank had actually
funded each of its relevant LIBOR Advances through the purchase of a Eurodollar
deposit bearing interest at the rate obtained pursuant to the definition of
LIBOR Rate in an amount equal to the amount of such LIBOR Advance and having a
maturity comparable to the relevant Interest Period; provided, however, that
Bank may fund each of its LIBOR Advances in any manner it sees fit and the
foregoing assumptions shall be utilized only for the purposes of calculating
amounts payable hereunder.

          (e) LIBOR Advances After Default. After the occurrence and during the
continuance of an Event of Default, (i) Borrower may not elect to have an
Advance be made or continued as, or converted to, a LIBOR Advance after the
expiration of any Interest Period then in effect for such Advance and (ii)
subject to the provisions hereof, any Notice of Conversion/Continuation given by
Borrower with respect to a requested conversion/continuation that has not yet
occurred shall be deemed to be rescinded by Borrower and be deemed a request to
convert or continue Advances referred to therein as Prime Rate Advances.

     3.7  Additional Requirements/Provisions Regarding LIBOR Advances.

          (a) If for any reason (including voluntary or mandatory
prepayment or acceleration), Bank receives all or part of the principal amount
of a LIBOR Advance prior to the last day of the Interest Period for such
Advance, Borrower shall immediately notify Borrower's account officer at Bank
and, on demand by Bank, pay Bank the amount (if any) by which (i) the additional
interest which would have been payable on the amount so received had it not been
received until the last day of such Interest Period exceeds (ii) the interest
which would have been recoverable by Bank by placing the amount so received on
deposit in the certificate of deposit markets, the offshore currency markets, or
United States Treasury investment products, as the case may be, for a period
starting on the date on which it was so received and ending on the last day of
such Interest Period at the interest rate determined by Bank in its reasonable
discretion. Bank's determination as to such amount shall be conclusive absent
manifest error.


<page>


          (b) Borrower shall pay Bank, upon demand by Bank, from time to
time such amounts as Bank may determine to be necessary to compensate it for any
costs incurred by Bank that Bank determines are attributable to its making or
maintaining of any amount receivable by Bank hereunder in respect of any
Advances relating thereto (such increases in costs and reductions in amounts
receivable being herein called "Additional Costs"), in each case resulting from
any Regulatory Change which:

               (i) changes the basis of taxation of any amounts payable to Bank
under this Agreement in respect of any Advances (other than changes which
affect taxes measured by or imposed on the overall net income of Bank by the
jurisdiction in which Bank has its principal office);

               (ii) imposes or modifies any reserve, special deposit
or similar requirements
relating to any extensions of credit or other assets of, or any deposits with,
or other liabilities of Bank (including any Advances or any deposits referred to
in the definition of LIBOR); or

               (iii) imposes any other condition affecting this Agreement (or
any of such extensions of credit or liabilities).

     Bank will notify Borrower of any event occurring after the Closing Date
which will entitle Bank to compensation pursuant to this Section as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation. Bank will furnish Borrower with a statement setting forth the
basis and amount of each request by Bank for compensation under this Section.
Determinations and allocations by Bank for purposes of this Section of the
effect of any Regulatory Change on its costs of maintaining its obligations to
make Advances, of making or maintaining Advances, or on amounts receivable by it
in respect of Advances, and of the additional amounts required to compensate
Bank in respect of any Additional Costs, shall be conclusive absent manifest
error.

          (c) If Bank shall determine that the adoption or implementation of any
applicable law, rule, regulation, or treaty regarding capital adequacy, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by Bank (or its
applicable lending office) with any respect or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank, or comparable agency, has or would have the effect of reducing the rate of
return on capital of Bank or any person or entity controlling Bank (a "Parent")
as a consequence of its obligations hereunder to a level below that which Bank
(or its Parent) could have achieved but for such adoption, change, or compliance
(taking into consideration policies with respect to capital adequacy) by an
amount deemed by Bank to be material, then from time to time, within fifteen
(15) days after demand by Bank, Borrower shall pay to Bank such additional
amount or amounts as will compensate Bank for such reduction. A statement of
Bank claiming compensation under this Section and setting forth the additional
amount or amounts to be paid to it hereunder shall be conclusive absent manifest
error.

          (d) If, at any time, Bank, in its sole and absolute discretion,
determines that (i) the amount of LIBOR Advances for periods equal to the
corresponding Interest Periods are not available to Bank in the offshore
currency interbank markets, or (ii) LIBOR does not accurately reflect the cost
to Bank of lending the LIBOR Advances, then Bank shall promptly give notice
thereof to Borrower. Upon the giving of such notice, Bank's obligation to make
the LIBOR Advances shall terminate; provided, however, Advances shall not
terminate if Bank and Borrower agree in writing to a different interest rate
applicable to LIBOR Advances.

          (e) If it shall become unlawful for Bank to continue to fund or
maintain any LIBOR Advances, or to perform its obligations hereunder, upon
demand by Bank, Borrower shall prepay the Advances in full with accrued interest
thereon and all other amounts payable by Borrower hereunder (including, without
limitation, any amount payable in connection with such prepayment pursuant to
Section 3.7(a)). Notwithstanding the foregoing, to the extent a determination by
Bank as described above relates to a LIBOR Advance then being requested by
Borrower pursuant to a Notice of Borrowing or a Notice of Conversion/
Continuation, Borrower shall have the option, subject to the provisions of
Section 3.6(c), to (i) rescind such Notice of Borrowing or Notice of Conversion/

     4        CREATION OF SECURITY INTEREST

     4.1 Grant of Security Interest. Borrower hereby grants Bank, to secure the
payment and performance in full of all of the Obligations, a continuing security
interest in, and pledges to Bank, the Collateral, wherever located, whether now
owned or hereafter acquired or arising, and all proceeds and products thereof.
Borrower represents, warrants, and covenants that the security interest granted
herein is and shall at all times continue to be a first priority perfected
security interest in the Collateral (subject only to Permitted Liens that may
have superior priority to Bank's Lien under this Agreement). If Borrower shall
acquire a commercial tort claim, Borrower shall promptly notify Bank in a
writing signed by Borrower of the general details thereof and grant to Bank in
such writing a security interest therein and in the proceeds thereof, all upon
the terms of this Agreement, with such writing to be in form and substance
reasonably satisfactory to Bank.

         If this Agreement is terminated, Bank's Lien in the Collateral shall
continue until the Obligations (other than inchoate indemnity obligations) are
repaid in full in cash. Upon payment in full in cash of the Obligations and at
such time as Bank's obligation to make Credit Extensions has terminated, Bank
shall, at Borrower's sole cost and expense, release its Liens in the Collateral
and all rights therein shall revert to Borrower.

     4.2 Authorization to File Financing Statements. Borrower hereby authorizes
Bank to file financing statements, without notice to Borrower, with all
appropriate jurisdictions to perfect or protect Bank's interest or rights
hereunder, including a notice that any disposition of the Collateral, by either
Borrower or any other Person, shall be deemed to violate the rights of Bank
under the Code.

     5    REPRESENTATIONS AND WARRANTIES

          Borrower represents and warrants as follows:

     5.1 Due Organization and Authorization. Borrower and each of its
Subsidiaries are duly existing and in good standing in their respective
jurisdictions of formation and are qualified and licensed to do business and
are in good standing in any jurisdiction in which the conduct of their business
or their ownership of property requires that they be qualified except where the
failure to do so could not reasonably be expected to have a material adverse
effect on Borrower's business. In connection with this Agreement, Borrower has
delivered to Bank Representations and Warranties form dated July 23, 2004 that
has been updated by Borrower in accordance with a letter from Borrower to Bank
letter dated February 14, 2006 (collectively, the "Perfection Certificate").
Borrower represents and warrants to Bank that (a) Borrower's exact legal name is
that indicated on the Perfection Certificate and on the signature page hereof;
(b) Borrower is an organization of the type and is organized in the jurisdiction
set forth in the Perfection Certificate; (c) the Perfection Certificate
accurately sets forth Borrower's organizational identification number or
accurately states that Borrower has none; (d) the Perfection Certificate
accurately sets forth Borrower's place of business, or, if more than one, its
chief executive office as well as Borrower's mailing address (if different than
its chief executive office); (e) Borrower (and each of its predecessors) has
not, in the past five (5) years, changed its jurisdiction of formation,
organizational structure or type, or any organizational number assigned by its
jurisdiction; and (f) all other information set forth on the Perfection
Certificate pertaining to Borrower and each of its Subsidiaries is accurate and
complete. If Borrower is not now a Registered Organization but later becomes
one, Borrower shall promptly notify Bank of such occurrence and provide Bank
with Borrower's organizational identification number.

     The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's organizational 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 have a material adverse effect on Borrower's business.

     5.2 Collateral; Other Property. Borrower has good title to, has rights in,
and the power to transfer each item of the Collateral upon which it purports to
grant a Lien hereunder, free and clear of any and all Liens except Permitted
Liens. Borrower has no deposit accounts other than the deposit accounts with
Bank, the deposit accounts, if any, described in the Perfection Certificate
delivered to Bank in connection herewith, or of which Borrower has given Bank
notice and taken such actions as are necessary to give Bank a perfected security
interest therein. The Accounts are bona fide, existing obligations of the
Account Debtors.


<page>


     The Collateral is not in the possession of any third party bailee (such
as a warehouse) except as otherwise provided in the Perfection Certificate. None
of the components of the Collateral shall be maintained at locations other than
as provided in the Perfection Certificate or as Borrower has given Bank notice
pursuant to Section 7.2. In the event that Borrower, after the date hereof,
intends to store or otherwise deliver any portion of the Collateral to a bailee,
then Borrower will first receive the written consent of Bank and such bailee
must execute and deliver a bailee agreement in form and substance satisfactory
to Bank in its sole discretion.

      Borrower is the sole owner of its intellectual property, except for
non-exclusive licenses granted to its customers in the ordinary course of
business. Each patent is valid and enforceable, and no part of the intellectual
property has been judged invalid or unenforceable, in whole or in part, and to
the best of Borrower's knowledge, 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 have a material adverse
effect on Borrower's business.


     5.3 Accounts Receivable. For any Eligible Account in any Borrowing Base
Certificate, all statements made and all unpaid balances appearing in all
invoices, instruments and other documents evidencing such Eligible Accounts are
and shall be true and correct and all such invoices, instruments and other
documents, and all of Borrower's Books are genuine and in all respects what they
purport to be. All sales and other transactions underlying or giving rise to
each Eligible Account shall comply in all material respects with all applicable
laws and governmental rules and regulations. Borrower has no knowledge of any
actual or imminent Insolvency Proceeding of any Account Debtor whose accounts
are an Eligible Account in any Borrowing Base Certificate. To the best of
Borrower's knowledge, all signatures and endorsements on all documents,
instruments, and agreements relating to all Eligible Accounts are genuine, and
all such documents, instruments and agreements are legally enforceable in
accordance with their terms.

     5.4 Litigation. There are no actions or proceedings pending or, to the
knowledge of the Responsible Officers, threatened in writing by or against
Borrower or any of its Subsidiaries involving more than $250,000.

     5.5 No Material Deviation in Financial Statements. All consolidated
financial statements for Borrower and any of its Subsidiaries 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.

     5.6 Solvency. The fair salable value of Borrower's assets (including
goodwill minus disposition costs) exceeds the fair value of its liabilities;
Borrower is not left with unreasonably small capital after the transactions in
this Agreement; and Borrower is able to pay its debts (including trade debts)
as they mature.

     5.7 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 have a material
adverse effect on its business. None of Borrower's or any of its Subsidiaries'
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 of its Subsidiaries have 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.

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


<page>


     5.9 Tax Returns and Payments; Pension Contributions. Borrower has timely
filed all required tax returns and reports, and Borrower has timely paid all
foreign, federal, state and local taxes, assessments, deposits and contributions
owed by Borrower. Borrower may defer payment of any contested taxes, provided
that Borrower (a) in good faith contests its obligation to pay the taxes by
appropriate proceedings promptly and diligently instituted and conducted, (b)
notifies Bank in writing of the commencement of, and any material development
in, the proceedings, (c) posts bonds or takes any other steps required to
prevent the governmental authority levying such contested taxes from obtaining a
Lien upon any of the Collateral that is other than a "Permitted Lien". Borrower
is unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid all amounts necessary to fund all present pension,
profit sharing and deferred compensation plans in accordance with their terms,
and Borrower has not withdrawn from participation in, and has not permitted
partial or complete termination of, or permitted the occurrence of any other
event with respect to, any such plan which could reasonably be expected to
result in any liability of Borrower, including any liability to the Pension
Benefit Guaranty Corporation or its successors or any other governmental agency.

     5.10 Use of Proceeds. Borrower shall use the proceeds of the Credit
Extensions solely as working capital and to fund its general business
requirements and not for personal, family, household or agricultural purposes.

     5.11     Bank Indebtedness as Senior Debt Per Indenture.

     All principal of, interest (including all interest accruing after the
commencement of any bankruptcy or similar proceeding, whether or not a claim for
post-petition interest is allowable as a claim in any such proceeding), and all
fees, costs, expenses and other amounts accrued or due under this Agreement
shall constitute "Senior Debt" under the terms of the Indenture.

     5.12 Full Disclosure. No written representation, warranty or other
statement of Borrower in any certificate or written statement given to Bank, as
of the date such representations, warranties, or other statements were made,
taken together with all such written certificates and written statements given
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 (it being recognized by Bank that the projections and
forecasts provided by Borrower in good faith and based upon reasonable
assumptions are not viewed as facts and that actual results during the period or
periods covered by such projections and forecasts may differ from the projected
or forecasted results).

     6    AFFIRMATIVE COVENANTS

     Borrower shall do all of the following:

     6.1 Government Compliance. Borrower shall, and shall cause each of its
Subsidiaries to, maintain its legal existence and good standing in its
jurisdiction of formation and each jurisdiction in which the nature of its
business requires them to be so qualified, except where the failure to take such
action would not reasonably be expected to have a material adverse effect on
Borrower's and its Subsidiaries' business or operations, taken as a whole;
provided, that (a) the legal existence of any Subsidiary that is not a Guarantor
may be terminated or permitted to lapse, and any qualification of such
Subsidiary to do business may be terminated or permitted to lapse, if, in the
good faith judgment of Borrower, such termination or lapse is in the best
interests of Borrower and its Subsidiaries, taken as a whole, and (b) Borrower
may not permit its qualification to do business in the jurisdiction of its chief
executive office to terminate or lapse; and provided, further, that this Section
6.2 shall not be construed to prohibit any other transaction that is otherwise

terms.

     6.5 Insurance. Keep its business and the Collateral insured for risks and

like value as the replaced or repaired Collateral and (ii) shall be deemed
Collateral in which Bank has been granted a first priority security interest,
and (b)(y) after the occurrence and during the continuance of an Event of
Default, all proceeds payable under such casualty policy shall, at the option
of Bank, be payable to Bank on account of the Obligations. If Borrower fails to
obtain insurance as required under this Section 6.5 or to pay any amount or
furnish any required proof of payment to third persons and Bank, Bank may make

     9     BANK'S RIGHTS AND REMEDIES

     9.1   Rights and Remedies.  While 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 a
Event of Default described in Section 8.5 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;

          (c) demand that Borrower (i) deposits cash with Bank in an amount
equal to the aggregate amount of any Letters of Credit remaining undrawn, as
collateral security for the repayment of any future drawings under such Letters
of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii)
pay in advance all Letter of Credit fees scheduled to be paid or payable over
the remaining term of any Letters of Credit;

          (d) terminate any FX Contracts;

          (e) settle or adjust disputes and claims directly with Account Debtors
for amounts on terms and in any order that Bank considers advisable, notify any
Person owing Borrower money of Bank's security interest in such funds, and
verify the amount of such account;

          (f) make any payments and do any acts it considers necessary or
reasonable to protect the Collateral and/or its security interest in the
Collateral. Borrower shall assemble the Collateral if Bank requests 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;

          (g) 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;

          (h) ship, reclaim, recover, store, finish, maintain, repair, prepare
for sale, advertise for sale, and sell the Collateral. Bank is hereby granted a
non-exclusive, royalty-free license or other right to use, without charge,
Borrower's labels, patents, copyrights, mask works, rights of use of any name,
trade secrets, trade names, trademarks, service marks, and advertising matter,
or 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;

          (i) place a "hold" on any account maintained with Bank and/or deliver
a notice of exclusive control, any entitlement order, or other directions or
instructions pursuant to any Control Agreement or similar agreements providing
control of any Collateral;

          (j) demand and receive possession of Borrower's Books; and

          (k) exercise all rights and remedies available to Bank under the Loan
Documents or at law or equity, including all remedies provided under the Code
(including disposal of the Collateral pursuant to the terms thereof).


<page>


     9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its
lawful attorney-in-fact, exercisable upon the occurrence and during the
continuance of an Event of Default, to: (a) endorse Borrower's name on any
checks or other forms of payment or security; (b) sign Borrower's name on any
invoice or bill of lading for any Account or drafts against Account Debtors; (c)
settle and adjust disputes and claims about the Accounts directly with Account
Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle,
and adjust all claims under Borrower's insurance policies; (e) pay, contest or
settle any Lien, charge, encumbrance, security interest, and adverse claim in or
to the Collateral, or any judgment based thereon, or otherwise take any action
to terminate or discharge the same; and (f) transfer the Collateral into the
name of Bank or a third party as the Code permits. Borrower hereby appoints Bank
as its lawful attorney-in-fact 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 until all Obligations
have been satisfied in full and Bank is under no further obligation to make
Credit Extensions hereunder. Bank's foregoing appointment as Borrower's
attorney in fact, and all of Bank's rights and powers, coupled with an interest,
are irrevocable until all Obligations have been fully repaid and performed and
Bank's obligation to provide Credit Extensions terminates.

     9.3 Accounts Verification; Collection. Whether or not an Event of Default
has occurred and is continuing, Bank may notify any Person owing Borrower money
of Bank's security interest in such funds and verify the amount of such account.
After the occurrence of an Event of Default, any amounts received by Borrower
shall be held in trust by Borrower for Bank, and, if requested by Bank, Borrower
shall immediately deliver such receipts to Bank in the form received from the
Account Debtor, with proper endorsements for deposit.

     9.4 Protective Payments. 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 highest applicable rate, and secured by the Collateral.
Bank will make reasonable efforts to provide Borrower with notice of Bank
obtaining such insurance at the time it is obtained or within a reasonable time
thereafter. No payments by Bank are deemed an agreement to make similar payments
in the future or Bank's waiver of any Event of Default.

     9.5 Application of Payments and Proceeds. Unless an Event of Default has
occurred and is continuing, Bank shall apply any funds in its possession,
whether from Borrower account balances, payments, or proceeds realized as the
result of any collection of Accounts or other disposition of the Collateral,
first, to Bank Expenses, including without limitation, the reasonable costs,
expenses, liabilities, obligations and attorneys' fees incurred by Bank in the
exercise of its rights under this Agreement; second, to the interest due upon
any of the Obligations; and third, to the principal of the Obligations and any
applicable fees and other charges, in such order as Bank shall determine in its
sole discretion. Any surplus shall be paid to Borrower or other Persons legally
entitled thereto; Borrower shall remain liable to Bank for any deficiency. If an
Event of Default has occurred and is continuing, Bank may apply any funds in its
possession, whether from Borrower account balances, payments, proceeds realized
as the result of any collection of Accounts or other disposition of the
Collateral, or otherwise, to the Obligations in such order as Bank shall
determine in its sole discretion. Any surplus shall be paid to Borrower or other
Persons legally entitled thereto; Borrower shall remain liable to Bank for any
deficiency. If Bank, in its good faith business judgment, directly or indirectly
enters into a deferred payment or other credit transaction with any purchaser at
any sale of Collateral, Bank shall have the option, exercisable at any time, of
either reducing the Obligations by the principal amount of the purchase price or
deferring the reduction of the Obligations until the actual receipt by Bank of
cash therefor.

     9.6 Bank's Liability for Collateral. So long as Bank complies with
reasonable banking practices regarding the safekeeping of the Collateral in the
possession or under the control of Bank, Bank shall not be liable or responsible
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.

     9.7 No Waiver; Remedies Cumulative. Bank's failure, at any time or times,
to require strict performance by Borrower of any provision of this Agreement or
any other Loan Document shall not waive, affect, or diminish any right of Bank
thereafter to demand strict performance and compliance herewith or therewith. No
waiver hereunder shall be effective unless signed by Bank and then is only
effective for the specific instance and purpose for which it is given. Bank's
rights and remedies under this Agreement and the other Loan Documents 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 in
exercising any remedy is not a waiver, election, or acquiescence.


<page>


     9.8 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.


     10  NOTICES

     11  CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE

     California law governs the Loan Documents without regard to principles
of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in Los Angeles County, California; provided,
however, that nothing in this Agreement shall be deemed to operate to preclude
Bank from bringing suit or taking other legal action in any other jurisdiction
to realize on the Collateral or any other security for the Obligations, or to
enforce a judgment or other court order in favor of Bank. Borrower expressly
submits and consents in advance to such jurisdiction in any action or suit
commenced in any such court, and Borrower hereby waives any objection that it
may have based upon lack of personal jurisdiction, improper venue, or forum non
conveniens and hereby consents to the granting of such legal or equitable relief
as is deemed appropriate by such court. Borrower hereby waives personal service
of the summons, complaints, and other process issued in such action or suit and
agrees that service of such summons, complaints, and other process may be made
by registered or certified mail addressed to Borrower at the address set forth
in Section 10 of this Agreement and that service so made shall be deemed
completed upon the earlier to occur of Borrower's actual receipt thereof or
three (3) days after deposit in the U.S. mails, proper postage prepaid.

     TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK
EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING
OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED
TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS
WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT.
EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.


<page>


     WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES' AGREEMENT TO WAIVE
THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a
trial by jury is not enforceable, the parties hereto agree that any and all
disputes or controversies of any nature between them arising at any time shall
be decided by a reference to a private judge, mutually selected by the parties
(or, if they cannot agree, by the Presiding Judge of the Santa Clara County,
California Superior Court) appointed in accordance with California Code of Civil
Procedure Section 638 (or pursuant to comparable provisions of federal law if
the dispute falls within the exclusive jurisdiction of the federal courts),
sitting without a jury, in Santa Clara County, California; and the parties
hereby submit to the jurisdiction of such court. The reference proceedings shall
be conducted pursuant to and in accordance with the provisions of California
Code of Civil Procedure ss.ss. 638 through 645.1, inclusive. The private judge
shall have the power, among others, to grant provisional relief, including
without limitation, entering temporary restraining orders, issuing preliminary
and permanent injunctions and appointing receivers. All such proceedings shall
be closed to the public and confidential and all records relating thereto shall
be permanently sealed. If during the course of any dispute, a party desires to
seek provisional relief, but a judge has not been appointed at that point
pursuant to the judicial reference procedures, then such party may apply to the
Santa Clara County, California Superior Court for such relief. The proceeding
before the private judge shall be conducted in the same manner as it would be
before a court under the rules of evidence applicable to judicial proceedings.
The parties shall be entitled to discovery which shall be conducted in the same
manner as it would be before a court under the rules of discovery applicable to
judicial proceedings. The private judge shall oversee discovery and may enforce
all discovery rules and order applicable to judicial proceedings in the same
manner as a trial court judge. The parties agree that the selected or appointed
private judge shall have the power to decide all issues in the action or
proceeding, whether of fact or of law, and shall report a statement of decision
thereon pursuant to the California Code of Civil Procedure ss. 644(a). Nothing
in this paragraph shall limit the right of any party at any time to exercise
self-help remedies, foreclose against collateral, or obtain provisional
remedies. The private judge shall also determine all issues relating to the
applicability, interpretation, and enforceability of this paragraph

     12   GENERAL PROVISIONS

service of a summons and complaint on an officer of Bank, or on any other person

sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Bank in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other

Agreement and the Loan Documents.

indemnify Bank shall survive until the statute of limitations with respect to
such claim or cause of action shall have run.

     12.9 Confidentiality. In handling any confidential information, Bank shall
exercise the same degree of care that it exercises for its own proprietary
information, but disclosure of information may be made: (a) to Bank's

interest in the Credit Extensions (provided, however, Bank shall use
commercially reasonable efforts to obtain such prospective transferee's or
purchaser's agreement to the terms of this provision); (c) as required by law,
regulation, subpoena, or other order; (d) to Bank's regulators or as otherwise
required in connection with Bank's examination or audit; and (e) as Bank

public domain after disclosure to Bank; or (ii) is disclosed to Bank by a third
party, if Bank does not know that the third party is prohibited from disclosing
the information.
