1             ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement shall be construed following GAAP.  Calculations and determinations must be made following GAAP.  Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13.  All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent such terms are defined therein.

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 Six Million Dollars ($6,000,000.00), inclusive of Credit Extensions relating to Sections 2.1.1, 2.1.3 and 2.1.4.  Such aggregate amounts utilized hereunder shall at all times reduce the amount otherwise available for Advances under the Revolving Line.  If, on the Revolving Line 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 reasonable 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.  Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or by Bank’s interpretations of any Letter of Credit issued by Bank for Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments, or supplements thereto.

(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 Six Million Dollars ($6,000,000.00) (the “FX Reserve”), inclusive of Credit Extensions relating to Sections 2.1.1, 2.1.2 and 2.1.4.  The aggregate amount of FX Forward Contracts at any one time may not exceed ten (10) times the amount of the FX Reserve.  The amount otherwise available for Credit Extensions under the Revolving Line shall be reduced by an amount equal to ten percent (10%) of each outstanding FX Forward Contract.  Any amounts needed to fully reimburse Bank will be treated as Advances under the Revolving Line and will accrue interest at the interest rate applicable to Advances.

2.1.4                     Cash Management Services Sublimit.  Borrower may use up to Six Million Dollars ($6,000,000.00) (the “Cash Management Services Sublimit”), inclusive of Credit Extensions relating to Sections 2.1.1, 2.1.2 and 2.1.3 of the Revolving Line 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”).  The dollar amount of any Cash Management Services provided under this sublimit will reduce the amount otherwise available under the Revolving Line.  Any amounts used or reserved by Borrower for any Cash Management Services will reduce the amount otherwise available for Credit Extensions under the Revolving Line.  Any amounts Bank pays on behalf of 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 outstanding 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.  Notwithstanding the foregoing, if at any time during any Non-Formula Period, the Credit Extensions outstanding under Sections 2.1.1, 2.1.2, 2.1.3 and 2.1.4 exceed the Non-Formula Amount (an “Overadvance”), then, within fifteen (15) days of the date of any such Overadvance (the “Overadvance Cure Period”), Borrower shall (a) make payments to Bank and/or deposit unrestricted cash with Bank in an amount sufficient to cure the Overadvance, or (b) provide Bank with a Borrowing Base Certificate which evidences that Borrower has Eligible Accounts equal to at least one hundred twenty-five percent (125%) of the aggregate amount of the Credit Extensions (not merely the Overadvance) which are outstanding under Sections 2.1.1, 2.1.2, 2.1.3 and 2.1.4.  Borrower may not have more than one (1) Overadvance Cure Period during each rolling thirty (30) day period.  The failure of Borrower to comply with the provision in the immediately preceding sentence shall result in an immediate Event of Default for which there shall be no grace or cure period.

2.3                               Payment of Interest on the Credit Extensions.

(a)                                  Interest Rate.  Subject to Section 2.3(b), the principal amount outstanding under the Revolving Line shall accrue interest at a floating per annum rate equal to the Prime Rate, which interest shall be payable monthly in arrears in accordance with Section 2.3(f) below.

(b)                                 Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear interest at a rate per annum which is four percentage points above the rate effective immediately before the Event of Default (the “Default Rate”).  Payment or acceptance of the increased interest rate provided in this Section 2.3(b) 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.

2

(c)           Adjustment to Interest Rate.  Changes to the interest rate of any Credit Extension based on changes to the Prime Rate shall be effective on the effective date of any change to the Prime Rate and to the extent of any such change.

(d)           360-Day Year.  Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed.

(e)           Debit of Accounts.  Bank may debit the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes Bank when due.  These debits shall not constitute a set-off.

(f)            Payments.  Unless otherwise provided, interest is payable monthly on the first (1^st) calendar cay of each month.  Payments of principal and/or interest received after 12:00 noon Eastern time are considered received at the opening of business on the next Business Day.  When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue.

2.4          Early Termination.  This Agreement may be terminated prior to the Revolving Line Maturity Date as follows: (i) by Borrower, effective three Business Days after written notice of termination is given to Bank; or (ii) by Bank at any time after the occurrence of  an Event of Default, without notice, effective immediately.  If this Agreement is terminated (A) by Bank in accordance with clause (ii) in the foregoing sentence, or (B) by Borrower for any reason, Borrower shall pay to Bank a termination fee in an amount equal to one percent (1.0%) of the Revolving Line (the “Early Termination Fee”).  The Early Termination Fee shall be due and payable on the effective date of such termination and thereafter shall bear interest at a rate equal to the highest rate applicable to any of the Obligations.  Notwithstanding the foregoing, Bank agrees to waive the Early Termination Fee if Bank agrees to refinance and redocument this Agreement under another division of Bank (in its sole and exclusive discretion) prior to the Revolving Line Maturity Date.

2.5          Fees.  Borrower shall pay to Bank:

(a)           Commitment Fee.  A non-refundable commitment fee of Twenty-Two Thousand Five Hundred Dollars ($22,500.00) was previously fully earned upon Borrower’s execution of the term sheet and shall be due and payable on the Effective Date;

(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;

(c)           Unused Revolving Line Facility Fee.  A fee (the “Unused Revolving Line Facility Fee”), payable quarterly, in arrears, on a calendar year basis, in an amount equal to one-half of one percent (0.50%) per annum of the average unused portion of the Revolving Line, as determined by Bank.  Borrower shall not be entitled to any credit, rebate or repayment of any Unused Revolving Line Facility Fee previously earned by Bank pursuant to this Section notwithstanding any termination of the Agreement or the suspension or termination of Bank’s obligation to make loans and advances hereunder;

(d)           Early Termination Fee.  The Early Termination Fee, when due and payable hereunder;

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.

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 terminate when the Obligations (other than inchoate indemnity obligations) are repaid in full in cash.  Upon payment in full in cash of the Obligations (other than inchoate indemnity 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, if any, are duly existing and in good standing, as Registered Organizations 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 a completed perfection certificate signed by Borrower (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 have a material adverse effect on Borrower’s business.

5

5.2                               Collateral.  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.

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection Certificate and except with respect to mobile equipment in possession of employees with an aggregate value not exceeding Fifty Thousand Dollars ($50,000.00).  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, except for mobile equipment in possession of employees with an aggregate value not exceeding Fifty Thousand Dollars ($50,000.00).  In the event that Borrower, after the date hereof, intends to store or otherwise deliver any portion of the Collateral to a bailee (except with respect to mobile equipment in possession of employees with an aggregate value not exceeding Fifty Thousand Dollars ($50,000.00)), 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 reasonable discretion.

All Inventory is in all material respects of good and marketable quality, free from material defects.

Except as noted on the Perfection Certificate, Borrower is not a party to, nor is bound by, any material license or other agreement with respect to which Borrower is the licensee that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property.  Borrower shall provide written notice to Bank within ten (10) days of entering or becoming bound by any such license or agreement which is reasonably likely to have a material impact on Borrower’s business or financial condition (other than over-the-counter software that is commercially available to the public).  Borrower shall take such steps as Bank requests to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for all such licenses or contract rights to be deemed “Collateral” and for Bank to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement (such consent or authorization may include a licensor’s agreement to a contingent assignment of the license to Bank if Bank determines that is necessary in its reasonable business judgment), whether now existing or entered into in the future.

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.  Except as set forth on the Perfection Certificate for Groove Mobile, Inc., 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 Two Hundred Fifty Thousand Dollars ($250,000.00).

5.5                               No Material Deterioration 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 of 1940.  Borrower is not engaged as one of its

6

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.

5.9          Tax Returns and Payments; Pension Contributions.  Borrower has timely filed all required tax returns and reports, and Borrower and its Subsidiaries have 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 not for personal, family, household or agricultural purposes.

5.11        Excluded Entities.  (a) The aggregate value of cash and Cash Equivalents held by the Excluded Entities does not and will not exceed, in the aggregate, Fifty Thousand Dollars ($50,000.00); and (b) the aggregate value of the tangible property held by each individual Excluded Entity does not exceed, in the aggregate, Two Hundred Thousand Dollars ($200,000.00) per Excluded Entity.

5.12        Full Disclosure.  No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank in connection with this Agreement, 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 in connection with this Agreement, 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, in light of the circumstances in which they were made, 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.  Except as permitted under Section 7.3, maintain its and all its Subsidiaries’ legal existence and good standing in their respective jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on Borrower’s business or operations.  Borrower shall comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, the noncompliance with which could have a material adverse effect on Borrower’s business.

11

8.6          Other Agreements.  If Borrower fails to (a) make any payment that is due and payable with respect to any Material Indebtedness and such failure continues after the applicable grace or notice period, if any, specified in the agreement or instrument relating thereto, or (b) perform or observe any other condition or covenant, or any other event shall occur or condition exist under any agreement or instrument relating to any Material Indebtedness, and such failure continues after the applicable grace or notice period, if any, specified in the agreement or instrument relating thereto and the effect of such failure, event or condition is to cause the holder or holders of such Material Indebtedness to accelerate the maturity of such Material Indebtedness or cause the mandatory repurchase of any Material Indebtedness;

8.7          Judgments.  A judgment or judgments for the payment of money in an amount, individually or in the aggregate, of at least One Hundred Thousand Dollars ($100,000) (not covered by independent third-party insurance) shall be rendered against Borrower and shall remain unsatisfied and unstayed for a period of ten (10) days after the entry thereof (provided that no Credit Extensions will be made prior to the satisfaction or stay of such judgment);

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, to the extent not prohibited by applicable law:

(a)           declare all Obligations immediately due and payable (but if an 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 Forward 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 at a location that is reasonably convenient to Bank and Borrower.  Bank may peaceably 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 by Borrower, to exercise any of Bank’s rights or remedies;

(g)           apply to the Obligations then due 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).

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

13

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 Bank’s security interest in the Collateral 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 charged by Bank, 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.  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 reasonable 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 applicable law and 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.

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.

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

Massachusetts 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 Massachusetts; provided, however, that if for any reason Bank cannot avail itself of such courts in the Commonwealth of Massachusetts, Borrower accepts jurisdiction of the courts and venue in Santa Clara County, California.  NOTWITHSTANDING THE FOREGOING, BANK SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANK’S RIGHTS AGAINST BORROWER OR ITS PROPERTY.
