RECITALS


          Borrower wishes to obtain credit from time to time from Bank, and Bank desires to extend credit to Borrower.  This Agreement sets forth the terms on which Bank will advance credit to Borrower, and Borrower will repay the amounts owing to Bank.


AGREEMENT


          The parties agree as follows:


          1.          DEFINITIONS AND CONSTRUCTION.


                       1.1          Definitions.  As used in this Agreement, unless otherwise defined, capitalized terms shall have the definitions set forth on Exhibit A.


                       1.2          Accounting Terms.  All accounting terms not specifically defined on Exhibit A shall be construed in accordance with GAAP and all calculations shall be made in accordance with GAAP.  The term “financial statements” shall include the accompanying notes and schedules.


          2.          LOANS AND TERMS OF PAYMENT.


                       2.1          Credit Extensions.  Borrower promises to pay to Bank, in lawful money of the United States of America, the aggregate unpaid principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit Extensions at rates in accordance with the terms hereof.


                                      (a)          Revolving Advances.


                                                     (i)          Subject to and upon the terms and conditions of this Agreement, Bank agrees to make advances (each a “Revolving Advance” and collectively, the “Revolving Advances”) to Borrower, subject to Section 2.1(a)(ii), in an aggregate outstanding amount not to exceed the Committed Revolving Line, minus the aggregate face amount of all Letters of Credit and minus the FX Amount and minus the outstanding Equipment Advances.  Amounts borrowed pursuant to this Section 2.1(a) may be repaid and reborrowed at any time
prior to the earlier to occur of (i) the Revolving Maturity Date, at which time all Revolving Advances under this Section 2.1(a) shall be immediately due and payable or (ii) the termination of Bank’s obligation to advance money pursuant to Section 9.1(b).  


1.











                                                     (ii)        Whenever Borrower desires a Revolving Advance, Borrower shall notify Bank (which notice shall be irrevocable) by facsimile transmission or telephone to be received no later than 12:00 noon Pacific Time, on the Business Day that the Revolving Advance is to be made.  Each such notification shall be promptly confirmed by a Payment/Advance Form in substantially the form of Exhibit C.  The notice shall be signed by a Responsible Officer or his or her designee.  Bank is authorized to make Revolving Advances under this Agreement, based upon instructions received from a
Responsible Officer or a designee of a Responsible Officer, or without instructions if in Bank’s discretion such Revolving Advances are necessary to meet Obligations which have become due and remain unpaid.  Bank shall be entitled to rely on any telephonic notice given by a person who Bank reasonably believes to be a Responsible Officer or a designee thereof, and Borrower shall indemnify and hold Bank harmless for any damages or loss suffered by Bank as a result of such reliance.  Bank will credit the amount of Revolving Advances made under this Section 2.1(a) to Borrower’s deposit account maintained with Bank.


                                                    (iii)       Borrower shall use Revolving Advances solely for working capital, the issuance of letters of credit, equipment purchases, permitted acquisitions described in this Agreement and other general corporate purposes.


                                      (b)          Letter of Credit Usage.  Subject to the availability under the Committed Revolving Line and in reliance on the representations and warranties of Borrower set forth herein, at any time and from time to time from the date hereof through the Business Day immediately prior to the Revolving Maturity Date, Bank shall issue for the account of Borrower such standby or commercial Letters of Credit in an aggregate face amount not to exceed the lesser of (i) the Committed Revolving Line minus the sum of (a) the aggregate principal amount of the outstanding Revolving Advances at the time of issuance of such Letter of Credit plus (b) the aggregate face amount of all
outstanding Letters of Credit at the time of issuance of such Letters of Credit plus (c) the FX Amount, and (ii) Five Million Dollars ($5,000,000).  The request for such Letters of Credit shall be made by delivering to Bank a duly executed letter of credit application on Bank’s standard form.  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 form application and letter of credit agreement (the “Application”).  Borrower will pay any standard issuance and other fees that Bank notifies Borrower will be charged for issuing and processing Letters of Credit for Borrower.  On any drawn but unreimbursed Letter of Credit, the unreimbursed amount shall be deemed a Revolving Advance under Section 2.1(a).  No Letter of Credit shall have an expiration date which is later than the Revolving Maturity Date unless Borrower shall deposit with Bank
cash collateral in an amount equal to or greater than one hundred five percent (105%) of the undrawn face amount of all such outstanding Letters of Credit. 


                                                     (i)          The obligation of Borrower to 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, the Application, and such Letters of Credit, under all circumstances whatsoever.  Borrower shall indemnify, defend, protect, and hold Bank harmless from any loss, cost, expense or liability, including, without limitation, reasonable attorneys’ fees, arising out of or in connection with any Letters of Credit, except for losses, costs, expenses or liabilities
caused by Bank’s gross negligence or willful misconduct.


2.











                                      (c)          Equipment Advances.


                                                     (i)          From the Closing Date through the first anniversary of the Closing Date, Bank agrees to make Equipment Advances to Borrower, in an aggregate outstanding amount not to exceed the Equipment Line.  The Equipment Advances shall not exceed one hundred percent (100%) of the invoice amount of the Equipment for which the Equipment Advance is requested, less taxes, freight, installation and other soft costs.  All such equipment invoices shall be approved by Bank.  


                                                     (ii)        Borrower shall provide notice to Bank of the requested Equipment Advance in substantially in the form of the Payment/Advance Form attached hereto as Exhibit C.  The notice shall be signed by a Responsible Officer or his or her designee and include a copy of the invoice for any Equipment to be financed, and shall include the serial numbers of such equipment.


                                      (d)          Foreign Exchange Sublimit.  Subject to and upon the terms and conditions of this Agreement and any other agreement that Borrower may enter into with the Bank in connection with foreign exchange transactions (“FX Contracts”), Borrower may request Bank to enter into FX Contracts with Borrower due not later than the Revolving Maturity Date.  Borrower shall pay any standard issuance and other fees that Bank notifies Borrower will be charged for issuing and processing FX Contracts for Borrower.  The FX Amount shall at all times be equal to or less than Five Million Dollars ($5,000,000).  The “FX Amount” shall equal the amount determined
by multiplying (i) the aggregate amount, in United States Dollars, of FX Contracts between Borrower and Bank remaining outstanding as of any date of determination by (ii) the applicable Foreign Exchange Reserve Percentage as of such date.  The “Foreign Exchange Reserve Percentage” shall be a percentage as determined by Bank, in its sole discretion from time to time.  The initial Foreign Exchange Reserve Percentage shall be ten percent (10%).


                       2.2          Overadvances.  If, at any time, (a) the aggregate amount of the outstanding Advances exceeds Twenty Million Dollars ($20,000,000); or (b) the aggregate amount of the outstanding Equipment Advances exceeds the Equipment Line, Borrower shall immediately pay to Bank, in cash, the amount of such excess.


                       2.3          Principal Repayments.


                                      (a)          Revolving Advances.  All Revolving Advances shall be due and payable on the Revolving Maturity Date.


                                      (b)          Equipment Advances.  The aggregate Equipment Advances outstanding on June 6, 2006 shall be due and payable in forty-two (42) equal monthly installments of principal, beginning on July 1, 2006 and continuing on the first day of each month thereafter through the Equipment Maturity Date.  The aggregate Equipment Advances outstanding on the first anniversary of the Closing Date and not already amortizing pursuant to the preceding sentence shall be due and payable in thirty six (36) equal monthly installments of principal, beginning December 16, 2006, and continuing on the first day of each month thereafter through the Equipment Maturity Date, at which time the
outstanding principal amount of all Equipment Advances, together with accrued but unpaid interest thereon, shall be immediately due and payable.


3.











                       2.4          Interest Rates, Payments, and Calculations.


                                      (a)          Interest Rates.  All Advances shall bear interest at the rates specified in the Libor Supplement.


                                      (b)          Default Rate.  All Obligations shall bear interest, from and after the occurrence and during the continuance of an Event of Default, at a rate equal to three (3) percentage points above the interest rate applicable immediately prior to the occurrence of the Event of Default.


                                      (c)          Payments.  Interest on Revolving Advances and Equipment Advances hereunder shall be due and payable in arrears on the first day of each month during the term hereof.  Bank may, at its option, charge such interest, all Bank Expenses, and all Periodic Payments against any of Borrower’s deposit accounts or against the Committed Revolving Line, in which case those amounts shall thereafter accrue interest at the rate then applicable hereunder.  Any interest not paid when due shall be compounded by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder.


                                      (d)          Computation.  In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such change in the Prime Rate.  All interest chargeable under the Loan Documents shall be computed on the basis of a 360 day year for the actual number of days elapsed.


                       2.5          Crediting Payments.  Prior to the occurrence of an Event of Default, Bank shall credit a wire transfer of funds, check or other item of payment to such deposit account or Obligation as Borrower specifies.  After the occurrence and during the continuance of an Event of Default, the receipt by Bank of any wire transfer of funds, check, or other item of payment shall be immediately applied to conditionally reduce Obligations, but shall not be considered a payment on account unless such payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment.  Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank after 12:00 noon
Pacific Standard Time shall be deemed to have been received by Bank as of the opening of business on the immediately following Business Day.  Whenever any payment to Bank under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension.


                       2.6          Fees.  Borrower shall pay to Bank the following:


                                      (a)          Unused Facility Fee.  On the first day of each calendar quarter, a fee equal to 0.0125% of the difference between the Committed Revolving Line and the average daily balance of outstanding Advances during the immediately prior calendar quarter. 


4.











                                      (b)          Bank Expenses.  On the Closing Date, all Bank Expenses incurred through the Closing Date, including reasonable attorneys’ fees and expenses up to $5,000 and, after the Closing Date, all Bank Expenses, including reasonable attorneys’ fees and expenses, as and when they become due.


                       2.7          Term.  This Agreement shall become effective on the Closing Date and, subject to Section 13.7, shall continue in full force and effect for a term ending on the Equipment Maturity Date.  


                       2.8          Prepayment; Reduction of Committed Revolving Line.  Upon two (2) Business Days prior written notice to Bank, Borrower may prepay the Credit Extensions in whole or in part without premium or penalty.  Any partial prepayment must be in a principal amount of at least Fifty Thousand Dollars ($50,000) or an integral multiple of Ten Thousand Dollars ($10,000) in excess thereof.  Upon two (2) Business Days prior written notice to Bank, Borrower may reduce or terminate the Committed Revolving Line to an amount not less than the then outstanding principal amount of all Revolving Advances; provided, that any partial reduction shall be in amount not less than Fifty Thousand Dollars ($50,000) or an integral multiple of Ten Thousand Dollars ($10,000)
in excess thereof.  Once reduced in accordance with this section, the Committed Revolving Line may not be increased.


          3.         CONDITIONS OF LOANS.


                       3.1          Conditions Precedent to Initial Credit Extension.  The obligation of Bank to make the initial Credit Extension is subject to the condition precedent that Bank shall have received, in form and substance satisfactory to Bank, the following:


                                      (a)          this Agreement;


                                      (b)          an officer’s certificate of Borrower with respect to incumbency and resolutions authorizing the execution and delivery of this Agreement;


                                      (c)          a financing statement (Form UCC-1);


                                      (d)          payment of the fees and Bank Expenses then due specified in Section 2.6;


                                      (e)          current financial statements in accordance with Section 6.2; and


                                      (f)          such other documents, and completion of such other matters, as Bank may reasonably deem necessary or appropriate.


                       3.2          Conditions Precedent to All Credit Extensions.  The obligation of Bank to make each Credit Extension, including the initial Credit Extension, is further subject to the following conditions:


                                      (a)          timely receipt by Bank of the Payment/Advance Form as provided in Section 2.1(a)(iii) and Section 2.1(b)(ii); and


5.











                                      (b)          the representations and warranties contained in Section 5 shall be true and correct in all material respects on and as of the date of such Payment/Advance Form and on the effective date of each Credit Extension as though made at and as of each such date, and no Event of Default shall have occurred and be continuing, or would exist after giving effect to such Credit Extension (provided, however, that those representations and warranties expressly referring to another date shall be true and correct in all material respects as of such date).  The making of each Credit Extension shall be deemed to be a representation and warranty by Borrower on the date of such
Credit Extension as to the accuracy of the facts referred to in this Section 3.2.


          4.          CREATION OF SECURITY INTEREST.


                       4.1          Grant of Security Interest.  Borrower grants and pledges to Bank a continuing security interest in all presently existing and hereafter acquired or arising Collateral to secure prompt repayment of any and all Obligations and to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents.  Except as set forth in the Disclosure Letter, and subject to Permitted Liens, such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and will constitute a valid, first priority security interest in later-acquired Collateral.  Notwithstanding any termination, Bank’s Lien on the Collateral shall remain in effect for so long as any Obligations are
outstanding.


                       4.2          Delivery of Additional Documentation Required.  Borrower shall from time to time execute and deliver to Bank, at the request of Bank, all Negotiable Collateral, all financing statements and other documents that Bank may reasonably request, in form satisfactory to Bank, to perfect and continue perfected Bank’s security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents.


          5.          REPRESENTATIONS AND WARRANTIES.


                       Borrower represents and warrants as follows:


                       5.1          Due Organization and Qualification.  Borrower is a corporation duly existing under the laws of its jurisdiction of incorporation and qualified and licensed to do business in any state in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to do so could not reasonably be expected to cause a Material Adverse Effect.


                       5.2          Due Authorization; No Conflict.  The execution, delivery, and performance of the Loan Documents are within Borrower’s corporate powers, have been duly authorized by all necessary corporate actions on the part of Borrower, and are not in conflict with nor constitute a breach of any provision contained in Borrower’s Certificate of Incorporation or Bylaws, nor will they constitute an event of default under any material agreement by which Borrower is bound.  Borrower is not in default under any agreement by which it is bound, which default could reasonably be expected to have a Material Adverse Effect.


                       5.3          Collateral.  Borrower has good title to the Collateral, free and clear of Liens, except for Permitted Liens. All Inventory is in all material respects of good and marketable quality, free from all material defects, except for Inventory for which adequate reserves have been made in accordance with GAAP. 


6.











                       5.4          Intellectual Property.  Borrower is the sole owner of its Intellectual Property, except for Licenses granted by Borrower to others in the ordinary course of business and Permitted Liens.  Each of Borrower’s Copyrights, Trademarks and Patents is valid and enforceable, and no part of the Borrower’s Intellectual Property has been judged invalid or unenforceable, in whole or in part, and no claim has been made that any part of its 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 Effect.  


                       5.5          Name; Location of Chief Executive Office.  Except as disclosed in the Disclosure Letter, Borrower has not done business under any name other than that specified on the signature page hereof.  The chief executive office of Borrower is located at the address indicated in Section 10 hereof.


                       5.6          Litigation.  Except as set forth in the Disclosure Letter, there are no actions or proceedings pending by or against Borrower or any Subsidiary before any court or administrative agency in which a likely adverse decision could reasonably be expected to have a Material Adverse Effect, or a material adverse effect on Borrower’s interest in or Bank’s security interest in the Collateral.


                       5.7          No Material Adverse Change in Financial Statements.  All consolidated financial statements of the Borrower and its Subsidiaries that are delivered by Borrower to Bank fairly present in all material respects Borrower’s consolidated financial condition as of the date thereof and Borrower’s consolidated results of operations for the period then ended.  There has not been a material adverse change in the consolidated financial condition of Borrower since the date of the most recent of such financial statements submitted to Bank.


                       5.8          Solvency, Payment of Debts.  Borrower is able to pay its debts (including trade debts) as they mature; the fair saleable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; and Borrower is not left with unreasonably small capital after the transactions contemplated by this Agreement.


                       5.9          Compliance with Laws and Regulations.  Borrower has met the minimum funding requirements of ERISA with respect to any employee benefit plans maintained by Borrower that are subject to ERISA.  No event has occurred resulting from Borrower’s failure to comply with ERISA that is reasonably likely to result in Borrower’s incurring any liability that could have a Material Adverse Effect.  Borrower is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.  Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for
the purpose of purchasing or carrying margin stock (within the meaning of Regulations T and U of the Board of Governors of the Federal Reserve System).  Borrower has complied in all material respects with all the provisions of the Federal Fair Labor Standards Act.  Borrower is in compliance with all environmental laws, regulations and ordinances except where the failure to comply could not reasonably be expected to have a Material Adverse Effect.  Borrower has not violated any statutes, laws, ordinances or rules applicable to it, the violation of which could have a Material Adverse Effect.  Borrower and each Subsidiary have filed or caused to be filed all tax returns required to be filed, and have paid, or have made adequate provision for the payment of, all taxes reflected therein except those being contested in good faith and for which adequate reserves are maintained in accordance with GAAP.


7.











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


                       5.11        Government Consents.  Borrower has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s business as currently conducted, except where the failure to do so could not reasonably be expected to cause a Material Adverse Effect.


                       5.12        Inbound Licenses.  Except as disclosed on the Disclosure Letter, Borrower is not a party to, nor is bound by, any license or other agreement that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property.


                       5.13        Deposit Accounts and Securities Accounts.  The name and address of each depository institution at which Borrower maintains any deposit account and the account number and account name of each such deposit account is listed in the Disclosure Letter.  The name and address of each securities intermediary or commodity intermediary at which Borrower maintains any securities account or commodity account and the account number and account name is listed in the Disclosure Letter.  


                       5.14        Full Disclosure.  No representation, warranty or other statement made by Borrower in any certificate or written statement furnished to Bank, taken together with all such certificates and written statements furnished to Bank and Borrower’s filings with the U.S. Securities and Exchange Commission, contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained in such 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 to be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may differ from the
projected or forecasted results.


          6.          AFFIRMATIVE COVENANTS.


                      Borrower covenants and agrees that, until payment in full of all outstanding Obligations, and for so long as Bank may have any commitment to make a Credit Extension hereunder, Borrower shall do all of the following:


                       6.1          Good
Standing and Government Compliance.  Except as otherwise provided in
Section 7.2, Borrower shall maintain its corporate existence in its
jurisdiction of incorporation and maintain qualification in each jurisdiction in
which the failure to so qualify could have a Material Adverse Effect. 
Borrower shall meet the minimum funding requirements of ERISA with respect to
any employee benefit plans maintained by Borrower and subject to ERISA. 
Borrower shall comply in all material respects, with all statutes, laws,
ordinances and government rules and regulations to which it is subject, and
shall maintain in force all licenses, approvals and agreements, the loss of
which or failure to comply with which could have a Material Adverse Effect, or a
material adverse effect on the Collateral or the priority of Bank’s Lien on
the Collateral.


8.

                       9.1          Rights and Remedies.  Upon the occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower:


                                      (a)          Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that upon the occurrence of an Event of Default described in Section 8.5, all Obligations shall become immediately due and payable without any action by Bank);


                                      (b)          Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement between Borrower and Bank;


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


                                      (d)          Make such payments and do such acts as Bank considers necessary or reasonable to protect its security interest in the Collateral.  Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate.  Borrower authorizes Bank to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s determination appears to be prior or superior to its security interest and to pay all expenses incurred in connection therewith.  With respect to any
of Borrower’s owned premises, Borrower hereby grants Bank a license to enter into possession of such premises and to occupy the same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise;


                                      (e)          Set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by Bank, or (ii) indebtedness at any time owing to or for the credit or the account of Borrower held by Bank;


15.











                                      (f)          Convert the Committed Revolving Line and the Equipment Line to a full remittance basis or a dominion of funds basis;


                                      (g)          Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral.  Bank is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s labels, Patents, Copyrights, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any property of a similar nature, 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
9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit;


                                      (h)          Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Bank determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate;


                                      (i)          Bank may credit bid and purchase at any public sale; and


                                      (j)          Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower.


                       9.2          Power of Attorney.  Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby irrevocably appoints Bank (and any of Bank’s designated officers, or employees) as Borrower’s true and lawful attorney to:  (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign Borrower’s name on any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral;
(e) make, settle, and adjust all claims under and decisions with respect to Borrower’s policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; and (g) to file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral; provided Bank may exercise such power of attorney to sign the name of Borrower on any of the documents described in Section 4.2 regardless of whether an Event of Default has occurred.  The appointment of Bank as Borrower’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and performed and Bank’s obligation to provide advances hereunder is terminated.


                       9.3          Accounts Collection.  Upon the occurrence and continuance of an Event of Default, Borrower shall collect all amounts owing to Borrower for Bank, receive in trust all payments as Bank’s trustee, and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper endorsements for deposit.


16.











                       9.4          Bank Expenses.  If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to Borrower:  (a) make payment of the same or any part thereof; (b) set up such reserves under the Revolving Facility as Bank deems necessary to protect Bank from the exposure created by such failure; or (c) obtain and maintain insurance policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank deems prudent.  Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, and shall bear
interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral.  Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default under this Agreement.


                       9.5          Bank’s Liability for Collateral.  So long as Bank complies with reasonable banking practices and Section 9207 of the UCC, Bank shall not in any way or manner be liable or responsible for:  (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other person whomsoever.  All risk of loss, damage or destruction of the Collateral shall be borne by Borrower.


                       9.6          Remedies Cumulative.  Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative.  Bank shall have all other rights and remedies not inconsistent herewith as provided under the UCC, by law, or in equity.  No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver.  No delay by Bank shall constitute a waiver, election, or acquiescence by it.  No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given.


                       9.7          Demand; Protest.

                       This Agreement shall be governed by,
and construed in accordance with, the internal laws of the State of California,
without regard to principles of conflicts of law.  Each of Borrower and
Bank hereby submits to the exclusive jurisdiction of the state and Federal
courts located in the County of Santa Clara, State of California.  BORROWER
AND BANK EACH HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM
OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY
OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT
CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY
CLAIMS.  EACH PARTY RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER
CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. 
EACH PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS
LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS
FOLLOWING CONSULTATION WITH LEGAL COUNSEL.


          12.        REFERENCE PROVISION.


                       12.1         In the event the Jury Trial Waiver set forth above is not enforceable, the parties elect to proceed under this Judicial Reference Provision.


                       12.2         With the exception of the items specified in Section 12.3 below, any controversy, dispute or claim (each, a “Claim”) between the parties arising out of or relating to this Agreement or any other Loan Document (collectively in this Section, the “Comerica Documents”), will be resolved by a reference proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Comerica Documents, venue for the reference proceeding will be in the state or federal court in the
county or district where the real property involved in the action, if any, is located or in the state or federal court in the county or district where venue is otherwise appropriate under applicable law (the “Court”).


18.











                       12.3         The matters that shall not be subject to a reference are the following: (i) nonjudicial foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This reference provision does not limit the right of any party to exercise or oppose any of the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does
not waive the right of any party to a reference pursuant to this reference provision as provided herein.


                       12.4         The referee shall be a retired judge or justice selected by mutual written agreement of the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted.  Pursuant to CCP § 170.6, each party shall have one peremptory challenge to the referee selected by the Presiding Judge of the Court (or his or her representative).


                       12.5         The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of decision within twenty (20) days after the matter has been submitted for decision.  


                       12.6         The referee will have power to expand or limit the amount and duration of discovery.  The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered based upon good cause shown, no party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding.


                       12.7         Except as expressly set forth herein, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding.  All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the
prevailing party, the parties will equally share the cost of the referee and the court reporter at trial.


19.











                       12.8         The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference.  Pursuant to CCP § 644, such decision shall
be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive.  The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the referee.  The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision.  


                       12.9         If the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration.   The arbitration will be conducted by a retired judge or justice, in accordance with the California Arbitration Act §1280 through §1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding.


                       12.10         THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER COMERICA DOCUMENTS.


          13.       GENERAL PROVISIONS.


                       13.1         Successors and Assigns.  This Agreement shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties; provided, however, that neither this Agreement nor any rights hereunder may be assigned by Borrower without Bank’s prior written consent, which consent may be granted or withheld in Bank’s sole discretion.  Bank shall have the right without the consent of or notice to Borrower to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights and benefits hereunder.


                       13.2         Indemnification.  Borrower shall defend, indemnify and hold harmless Bank and its officers, employees, and agents against:  (a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with the transactions contemplated by this Agreement; and (b) all losses or Bank Expenses in any way suffered, incurred, or paid by Bank as a result of or in any way arising out of, following, or consequential to transactions between Bank and Borrower whether under this Agreement, or otherwise (including without limitation reasonable attorneys fees and expenses), except for obligations, demands, claims, liabilities and losses caused by Bank’s gross negligence or willful misconduct.


20.











                       13.3         Time of Essence.  Time is of the essence for the performance of all obligations set forth in this Agreement.


                       13.4         Severability of Provisions.  Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision.


                       13.5         Amendments in Writing, Integration.  This Agreement amends and restates the terms of the Loan and Security Agreement dated as of December 20, 2002, as amended through the date hereof.  All amendments to or terminations of this Agreement must be in writing.  All prior agreements, understandings, representations, warranties, and negotiations between the parties hereto with respect to the subject matter of this Agreement, if any, are merged into this Agreement and the Loan Documents, provided that any financing statements filed before the Closing Date shall continue to perfect Bank’s Lien to secure the Obligations.


                       13.6         Counterparts.  This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement.


                       13.7         Survival.  All covenants, representations and warranties made in this Agreement shall continue in full force and effect so long as any Obligations remain outstanding.  The obligations of Borrower to indemnify Bank with respect to the expenses, damages, losses, costs and liabilities described in Section 13.2 shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Bank have run.


                       13.8         Confidentiality.  In handling any confidential information of Borrower, Bank and all employees and agents of Bank shall exercise the same degree of care that Bank exercises with respect to its own proprietary information of the same types to maintain the confidentiality of any non-public information thereby received or received pursuant to this Agreement except that disclosure of such information may be made (i) to the subsidiaries or affiliates of Bank in connection with their present or prospective business relations with Borrower provided that they have entered into a comparable confidentiality agreement in favor of Borrower and have delivered a copy to Borrower, (ii) to prospective transferees or purchasers of any interest in the Credit
Extensions, provided that they have entered into a comparable confidentiality agreement in favor of Borrower and have delivered a copy to Borrower, (iii) as required by law, regulations, rule or order, subpoena, judicial order or similar order, (iv) as may be required in connection with the examination, audit or similar investigation of Bank and (v) as Bank may determine in connection with the enforcement of any remedies hereunder.  Confidential information hereunder shall not include information that either:  (a) is in the public domain or in the knowledge or possession of Bank when disclosed to Bank, or becomes part of the public domain after disclosure to Bank through no fault of Bank; or (b) is disclosed to Bank by a third party, provided Bank does not have actual knowledge that such third party is prohibited from disclosing such information.
