Exhibit 10.1

LOAN AND SECURITY AGREEMENT

     THIS LOAN AND SECURITY AGREEMENT (this “Agreement”) dated as of March 29, 2010 (the “Effective Date”) between SILICON VALLEY BANK, a California corporation (“Bank”), and CARDIOVASCULAR SYSTEMS, INC., a Delaware corporation (“Borrower”), provides the terms on which Bank shall lend to Borrower and Borrower shall repay Bank. This Agreement amends and restates in its entirety the Loan and Security Agreement, dated September 12, 2008, between Borrower and Bank, as the same has from time to time been previously amended (the “Prior LSA”). Except for the provisions of the Prior LSA being amended and restated in this Agreement, all other existing documents, instruments and agreements by Borrower with or in favor of Bank shall continue in full force and effect, including all UCC-1 financing statements and other documents filed with governmental offices which perfect liens or security interests in favor of Bank. The parties agree as follows:

     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 and to deduction of Reserves, Bank shall make Advances not exceeding the Availability Amount. Amounts borrowed hereunder may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. The outstanding “Advances” under the Revolving Line pursuant to the Prior LSA shall be the beginning balance of the Advances under this Agreement, which Borrower agrees are owed without any defense, offset or counter-claim of any kind.

          (b) Streamline Period. During certain periods of time (each, a “Streamline Period”), provided that the Streamline Requirements are all met, Borrower’s reporting requirements shall be reduced, and certain proceeds shall be deposited in Borrower’s operating accounts instead of being applied to the Advances, as set forth in other provisions of this Agreement. Such a Streamline Period shall be deemed to be in effect as of the Effective Date. If at any time during any Streamline Period the Streamline Requirements are not met, upon written notice from Bank to Borrower the Streamline Period shall immediately cease to be effective, and any terms or conditions of this Agreement that are dependent upon the existence of a Streamline Period will immediately revert to the respective terms and conditions that are to be in force when a Streamline Period is not in effect, without the need for any further action on the part of Bank or Borrower. Further, if following the cessation of a Streamline Period the Streamline Requirements are thereafter satisfied for a period of at least 60 days (for which period Borrower must have confirmed via its monthly Compliance Certificates that the Streamline Requirements were satisfied as of two consecutive month ends during such period), Borrower may elect to again put a Streamline Period into effect pursuant to the terms hereof by giving Bank at least 30 days prior written notice, specifying the date the Streamline Period is to begin. Thus, it is the intention of the parties that Borrower have the opportunity for successive Streamline Periods to apply when and to the extent the conditions thereto are satisfied.

          (c) 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. Borrower may terminate the Revolving Line

prior to the Revolving Line Maturity Date, effective five (5) Business Days after written notice of termination is given to Bank, on which date Borrower shall repay the principal amount of all Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line. If the Borrower terminates the Revolving Line prior to the Revolving Line Maturity Date, or if Bank terminates the Revolving Line prior to the Revolving Line Maturity Date due to the occurrence and continuance of an Event of Default, or if the Obligations under the Revolving Line otherwise become due and payable as the result of an Event of Default (including, without limitation, becoming due and payable as the result of an Insolvency Proceeding), Borrower shall immediately pay to Bank, in addition to the payment of any other expenses or fees then-owing, a termination fee in an amount equal to (i) 2% of the Maximum Dollar Amount if such termination or becoming due and payable occurs on or before the first year anniversary of the Effective Date or (ii) 1% of the Maximum Dollar Amount if such termination or becoming due and payable occurs after the first year anniversary of the Effective Date but before the second year anniversary of Effective Date. Without limitation on the fact that such fee shall be due as set forth in the preceding sentence, such fee shall bear interest until paid at a rate equal to the highest rate applicable to the Revolving Line. Notwithstanding any termination of the Revolving Line, Bank’s liens and security interests in the Collateral and all of Bank’s rights and remedies under this Agreement shall continue until Borrower fully satisfies all Obligations.

     2.1.2 Letters of Credit Sublimit.

          (a) Availability. As part of the Revolving Line, Bank shall issue or have issued Letters of Credit denominated in Dollars or a Foreign Currency for Borrower’s account. The aggregate Dollar Equivalent amount utilized for the issuance of Letters of Credit shall at all times reduce the amount otherwise available for Advances under the Revolving Line. The aggregate Dollar Equivalent of the face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) may not exceed the lesser of (A) One Million Dollars ($1,000,000), minus (i) the sum of all amounts used for Cash Management Services, and minus (ii) the FX Reduction Amount, or (B) the lesser of the Maximum Dollar Amount or the Borrowing Base, minus (i) the sum of all outstanding principal amounts of any Advances (including any amounts used for Cash Management Services), and minus (ii) the FX Reduction Amount.

          (b) Cash Collateral: Documentation; Liability. If, on the Revolving Line Maturity Date (or the effective date of any termination of this Agreement), 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 Dollar Equivalent 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 such 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.

          (c) Reimbursement for Draws. 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.

          (d) Foreign Currency Letters of Credit. 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 Dollar Equivalent of the amount thereof (plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges).

          (e) Letter of Credit Reserve. 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 (the “FX Reserve”). The aggregate amount of FX Forward Contracts at any one time may not exceed ten (10) times the lesser of (A) One Million Dollars ($1,000,000), minus (i) the sum of all amounts used for Cash Management Services, and minus (ii) the aggregate Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), or (B) the lesser of Maximum Dollar Amount or the Borrowing Base, minus (i) the sum of all outstanding principal amounts of any Advances (including any amounts used for Cash Management Services), and minus (ii) the Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit 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 (the “FX Reduction Amount”). Any amounts needed to fully reimburse Bank for any amounts not paid by Borrower in connection with FX Forward Contracts 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 the Revolving Line for Bank’s cash management services, which may include merchant services, direct deposit of payroll for which Bank has credit exposure, business credit card, and check cashing services identified in Bank’s various cash management services agreements (collectively, the “Cash Management Services”), in an aggregate amount not to exceed the lesser of (A) One Million Dollars ($1,000,000), minus (i) the aggregate Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), and minus (ii) the FX Reduction Amount, or (B) the lesser of Maximum Dollar Amount or the Borrowing Base, minus (i) the sum of all outstanding principal amounts of any Advances, minus the Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), and minus (ii) the FX Reduction Amount. 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.

     2.1.5 Term Loan.

          (a) Availability Combination of Term Loans. Term Loan A and Term Loan C are outstanding pursuant to the Prior LSA in the outstanding principal balances of $1,795,670.12 and $3,792,949.96, respectively, as of March 29, 2010. Within five (5) days from the Effective Date, Bank shall make a term loan to Borrower in an amount (the “New Term Loan Advance”) equal to the Term Loan Commitment Amount minus the sum of the outstanding principal balances of Term Loan A and Term Loan C as of the date of the New Term Loan Advance, subject to the satisfaction of the terms and conditions of this Agreement. Effective upon Bank making the New Term Loan Advance, its balance shall be combined with the outstanding balances of Term Loan A and Term Loan C to constitute the “Term Loan” referred to in this Agreement and thereafter such combined loans shall be subject to the terms of this Agreement and not the terms of the Prior LSA. No portion of the Term Loan may be reborrowed after repayment.

          (b) Repayment. Borrower shall continue to pay interest on Term Loan A and Term Loan C in accordance with the Prior LSA until the New Term Loan Advance is made. The Borrower shall pay Bank accrued interest on the Term Loan beginning on the first day of the calendar month following the month during which the New Term Loan Advance is made and continuing on the same day of each succeeding month. Borrower shall repay the Term Loan in 30 equal monthly payments of principal and accrued interest, each in the amount necessary to fully amortize the Term Loan over such period (such amount to be calculated by Bank), commencing on November 1, 2010 and continuing on the first day of each calendar month thereafter until the Term Loan Maturity Date on which date the entire unpaid principal balance of the Term Loan, plus the Final Payment, plus any

and all accrued and unpaid interest, and plus all other sums, if any, that shall have become due and payable hereunder with respect to the Term Loan, shall be paid.

          (c) Mandatory Prepayment. Reference is made to the definition of “Borrowing Base” (contained in Section 13.1) which subtracts the amount of the Full Term Loan Reserve, to the extent it is in effect, in calculating the Borrowing Base. If at any time, and from time to time, such a subtraction of the amount of the Full Term Loan Reserve shall cause the Borrowing Base to be less than zero, then Borrower shall immediately make a prepayment of the principal of Term Loan in the amount by which zero exceeds the Borrowing Base.

          (d) Permitted Prepayment. At Borrower’s option, so long as an Event of Default has not occurred and is not continuing, Borrower shall have the option to prepay all, but not less than all, of the Term Loan, provided Borrower (i) provides written notice to Bank of its election to prepay the Term Loan at least thirty (30) days prior to such prepayment, and (ii) pays, on the date of the prepayment (A) all accrued and unpaid interest with respect to the Term Loan through the date the prepayment is made; (B) all unpaid principal with respect to the Term Loan; (C) a fee equal to the Make-Whole Premium; (D) the Final Payment; and (E) all other sums, if any, that shall have become due and payable hereunder with respect to the Term Loan. Without limitation on the fact that such amounts shall be due on the date of the prepayment, they shall bear interest from the date due until paid at a rate equal to the highest rate applicable to the Term Loan.

          (e) Fee and Final Payment Due Upon Acceleration. If all or any portion of the Term Loan has become due and payable according to the terms hereof because of the occurrence and continuance of an Event of Default, Borrower shall pay to Bank on the date that it has become due and payable according to the terms hereof, in addition to any other sums owing, a fee equal to the Make-Whole Premium, plus the Final Payment. Without limitation on the fact that such amounts shall be due as set forth in the preceding sentence, they shall bear interest from the date due until paid at a rate equal to the highest rate applicable to the Term Loan.

     2.2 Overadvances. If, at any time, the sum of (a) the outstanding principal amount of any Advances (including any amounts used for Cash Management Services), plus (b) the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), plus (c) the FX Reduction Amount, exceeds the lesser of either the Maximum Dollar Amount or the Borrowing Base (such excess being an “Overadvance”), Borrower shall immediately pay to Bank in cash such Overadvance. Without limiting Borrower’s obligation to repay Bank any amount of the Overadvance, Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance, on demand, at the Default Rate.

     2.3 Payment of Interest on the Credit Extensions.

          (a) Interest Rate.

               (i) Advances. 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 2.0 percentage points above the Prime Rate, provided that the interest rate in effect on any day shall not be less than 6.0% per annum, which interest shall be payable monthly.

               (ii) Term Loan. Subject to Section 2.3(b), the principal amount outstanding under the Term Loan shall accrue interest at a per annum rate equal to 9.0%, which interest shall be payable monthly.

          (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 five percentage points (5.00%) above the rate that is otherwise applicable thereto (the “Default Rate”) unless Bank otherwise elects from time to time in its sole discretion to impose a smaller increase. Fees and expenses which are required to be paid by Borrower pursuant to the Loan Documents (including, without limitation, Bank Expenses) but are not paid when due shall bear interest until paid at a rate equal to the highest rate applicable to the Obligations. 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.

          (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 any of Borrower’s deposit accounts, including 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) Payment; Interest Computation; Float Charge. Unless otherwise provided, interest is payable monthly on the last calendar day of each month (including with respect to interest on amount outstanding under the Revolving Line). In computing interest, (i) all Payments received after 12:00 p.m. Pacific time on any day shall be deemed received at the opening of business on the next Business Day, and (ii) the date of the making of any 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. In addition, Bank shall be entitled to charge Borrower a “float” charge in an amount equal to two (2) Business Days interest, at the interest rate applicable to the Advances whether or not any Advances are outstanding, on all Payments received by Bank, unless at the time of receipt a Streamline Period is in effect and no Event of Default has occurred and is continuing. The float charge for each month shall be payable on the last day of the month. Bank shall not, however, be required to credit Borrower’s account for the amount of any item of payment which is unsatisfactory to Bank in its good faith business judgment, and Bank may charge Borrower’s Designated Deposit Account for the amount of any item of payment which is returned to Bank unpaid.

     2.4 Fees. Borrower shall pay to Bank:

          (a) Commitment Fee. A fully earned, non-refundable commitment fee of (i) $125,000 on the Effective Date, and (ii) $110,000 on the first anniversary of the Effective Date; and

          (b) Letter of Credit Fees. Bank’s customary fees and expenses for the issuance or renewal of Letters of Credit, including, without limitation, a letter of credit fee of two percent (2.00%) per annum of the Dollar Equivalent of the face amount of each Letter of Credit issued, upon the issuance of such Letter of Credit, each anniversary of the issuance during the term of such Letter of Credit, and upon the renewal of such Letter of Credit by Bank; and

          (c) Collateral Monitoring Fee. A collateral monitoring fee of $1,000 for each month during which either (i) the Streamline Period is not in effect for the entire month or (ii) an Event of Default has occurred, payable in arrears on the last day of each month (prorated for any partial month at the beginning and upon termination of this Agreement); and

          (d) Unused Revolving Line Facility Fee. A fee (the “Unused Revolving Line Facility Fee”), payable monthly, in arrears, on a calendar year basis, in an amount equal to 0.375% per annum of the average unused portion of the Revolving Line, as determined by Bank. The unused portion of the Revolving Line, for the purposes of this calculation, shall not include amounts utilized or reserved with respect to products provided in connection with Cash Management Services, Letters of Credit or pursuant to the Partial Term Loan Reserve or Full Term Loan Reserve, or the FX Reduction Amounts. 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 this Agreement or the suspension or termination of Bank’s obligation to make loans and advances hereunder; and

          (e) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses, and expenses for documentation and negotiation of this Agreement) incurred through and after the Effective Date, when due (or, if there is no stated due date, upon demand by Bank).

     2.5 Payments; Application of Payments.

          (a) All payments (including prepayments) to be made by Borrower under any Loan Document shall be made in immediately available funds in U.S. Dollars, without setoff or counterclaim, before 12:00 p.m. Pacific time on the date when due. Payments of principal and/or interest received after 12:00 p.m. Pacific time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment shall be due the next Business Day, and additional fees or interest, as applicable, shall continue to accrue until paid.

          (b) All payments with respect to the Obligations may be applied in such order and manner as Bank shall determine in its sole discretion. Borrower shall have no right to specify the order or the accounts to which Bank shall allocate or apply any payments required to be made by Borrower to Bank or otherwise received by Bank under this Agreement when any such allocation or application is not specified elsewhere in this Agreement.

     3 CONDITIONS OF LOANS

     3.1 Conditions Precedent to New Term Loan Advance. Bank’s obligation to make the New Term Loan Advance is subject to the condition precedent that Borrower shall have delivered, in form and substance satisfactory to Bank, such documents, and completed such other matters, as Bank may reasonably deem necessary or appropriate, including, without limitation:

          (a) duly executed original signatures to the Loan Documents to which it is a party;

          (b) duly executed original signatures to the Warrant;

          (c) its Operating Documents and a good standing certificate of Borrower certified by the Secretary of State of the State of Delaware as of a date no earlier than thirty (30) days prior to the Effective Date;

          (d) duly executed original signatures to the completed Borrowing Resolutions for Borrower;

          (e) if any loan agreement has been entered into between Borrower and PFG, duly executed original signatures to a subordination agreement by PFG, in favor of Bank and acceptable to Bank in its sole discretion, and consented to by Borrower, whereby PFG subordinates the repayment of, and any liens securing, any indebtedness of Borrower to PFG, and agrees not to exercise any of its rights or remedies in connection therewith for a period of time acceptable to Bank;

          (f) certified copies, dated as of a recent date, of financing statement searches, as Bank shall request, accompanied by written evidence (including any UCC termination statements) that the Liens indicated in any such financing statements either constitute Permitted Liens or have been or, in connection with the initial Credit Extension, will be terminated or released;

          (g) a new, updated, Perfection Certificate executed by Borrower;

          (h) a copy of its Registration Rights Agreement and any amendments thereto;

          (i) a landlord’s consent in favor of Bank for each of Borrower’s locations by the respective landlords thereof, together with the duly executed original signatures thereto (provided that Borrower may have up to 30 days after the Effective Date to provide the same to Bank); and

          (j) payment of the fees and Bank Expenses then due as specified in Section 2.4 hereof.

     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 conditions precedent:

          (a) (i) to obtain an Advance, except as otherwise provided in Section 3.4, timely receipt of an executed Transaction Report, and (ii) to obtain the New Term Loan Advance, timely receipt of an executed Payment/Advance Form;

          (b) the representations and warranties in this Agreement shall be true in all material respects on the date of the Transaction Report or Payment/Advance Form (as applicable) and on the Funding 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 occurred and be continuing or result from the Credit Extension. Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties in this Agreement remain true in all material respects; 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

          (c) in Bank’s good faith business judgment, there has not been a Material Adverse Change.

     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 precedent to any Credit Extension. Borrower expressly agrees that a Credit Extension made 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 Credit Extension in the absence of a required item shall be made in Bank’s sole discretion.

     3.4 Procedures for Borrowing Advances. Subject to the prior satisfaction of all other applicable conditions to the making of an Advance set forth in this Agreement, to obtain an Advance, Borrower shall notify Bank (which notice shall be irrevocable) by electronic mail, facsimile, or telephone by 12:00 p.m. Pacific time on the Funding Date of the Advance. Together with such notification, Borrower must promptly deliver to Bank by electronic mail or facsimile a completed Transaction Report executed by a Responsible Officer or his or her designee. Bank shall credit Advances to the Designated Deposit Account. Bank may make Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee.

     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. The grant of security interest and pledge by Borrower contained herein is without limitation on any security interest granted by Borrower under any other Loan Document and without limitation on the security interests granted by Borrower under the Prior LSA, which security interests granted under the Prior LSA shall continue, uninterrupted, as amended and restated by this Agreement.

     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 (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, warrants and agrees as follows:

     5.1 Due Organization and Authorization. Borrower is duly existing and in good standing in its jurisdiction of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the failure to do so could not reasonably be expected to cause a Material Adverse Change. In connection with this Agreement, Borrower has delivered to Bank a completed certificate signed by Borrower entitled “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 (except as previously consented to in writing by Bank); and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete (it being understood and agreed that Borrower may from time to time update certain information in the Perfection Certificate after the Effective Date to the extent permitted by one or more specific provisions in this Agreement). 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 by Borrower of the Loan Documents to which it is a party have been duly authorized, and do not (i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate any applicable order, writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any of its Subsidiaries or any of their property or assets may be bound or affected, (iv) require any action by, filing, registration, or qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and effect), or (v) constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could reasonably be expected to cause a Material Adverse Change.

     5.2 Collateral. Borrower has good title to the Collateral, free of Liens except Permitted Liens. Borrower has no Collateral Accounts other than (a) the Collateral Accounts with Bank and (b) the Collateral Accounts, if any, described in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice, for which Borrower has taken such actions as are necessary to give Bank a perfected security interest therein, pursuant to documentation reasonably acceptable to Bank. 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. None of the components of the Collateral shall be maintained at locations other than as provided in the Perfection Certificate or as permitted 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.

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

     Borrower is the sole owner of the Intellectual Property which it owns or purports to own except for (a) non-exclusive licenses granted to its customers in the ordinary course of business, (b) over-the-counter software that is commercially available to the public, and (c) material Intellectual Property licensed to Borrower and noted on the Perfection Certificate. Each Patent which it owns or purports to own and which is material to Borrower’s business is valid and enforceable, and no part of the Intellectual Property which Borrower owns or purports to own and which is material to Borrower’s business has been judged invalid or unenforceable, in whole or in part. 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 would not reasonably be expected to have a material adverse effect on Borrower’s business.

     Except as noted on the Perfection Certificate, Borrower is not a party to, nor is it bound by, any Restricted License.

     5.3 Accounts Receivable; Inventory.

          (a) For each Account with respect to which Advances are requested, on the date each Advance is requested and made, such Account shall be an Eligible Account.

          (b) All statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing the 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 and will have no knowledge of any actual or imminent Insolvency Proceeding of any Account Debtor whose accounts are shown as Eligible Accounts in any Transaction Report. To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Accounts are and will be genuine, and all such documents, instruments and agreements are and will be legally enforceable in accordance with their terms.

          (c) For any item of Inventory consisting of Eligible Inventory in any Transaction Report, such Inventory (i) consists of raw materials or finished goods, in good, new, and salable condition, which is not perishable, returned, consigned, obsolete, not sellable, slow moving, damaged, or defective, and is not comprised of demonstrative or custom inventory, works in progress, packaging or shipping materials, or supplies; (ii) meets all applicable governmental standards; (iii) has been manufactured in compliance with the Fair Labor Standards Act; (iv) is not subject to any Liens, except the first priority Liens granted or in favor of Bank under this Agreement or any of the other Loan Documents; and (v) is located at the locations identified by Borrower in the Perfection Certificate where it maintains Inventory (or at any location permitted under Section 7.2).

     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, except as disclosed in the Perfection Certificate.

     5.5 Financial Statements; Financial Condition. 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, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company” as each term is defined and used in the Public Utility Holding

Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to cause a Material Adverse Change. None of Borrower’s or any 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 their respective businesses as currently conducted.

     5.8 Subsidiaries; Investments. Other than as disclosed in the Perfection Certificate, Borrower does not have any Subsidiaries, other than Subsidiaries organized with the prior written consent of Bank, and does not own any stock, partnership interest or other equity securities in any other Person, except for Permitted Investments.

     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 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 representation, warranty, or other statement was 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).

     5.12 UBS Loan. On August 21, 2008, Borrower received net proceeds of $11,000,000 from a loan by UBS Bank USA to Borrower, and as of the Effective Date, including such loan Borrower has loans outstanding from UBS Bank USA in the aggregate of $19,168,793, including principal and accrued interest, and Borrower can borrow additional amounts from UBS Bank USA that would allow such aggregate amount of loans outstanding to increase to $19,325,000 of principal and accrued interest (collectively, the “UBS Loans”). Borrower has provided Bank copies of all of the agreements, instruments and documents relating to the UBS Loans, including Borrower’s acceptance on November 7, 2008 of an offer of Rights to sell the ARS to UBS during the period June 30, 2010 through July 2, 2012, at par value (the “UBS Loan Documents”). The UBS Loans are secured only by the Auction Rate Securities (UBS), and the UBS Loan Documents do not require Borrower to provide or contemplate Borrower providing any additional collateral or proceeds from any other Borrower assets, except that the UBS Loan Documents require Borrower to repay the UBS Loans in the event that Borrower receives net proceeds exceeding $50,000,000 from an initial public offering of Borrower’s stock.

     5.13 Indebtedness. Borrower is not liable for any Indebtedness other than Permitted Indebtedness.

     5.14 Definition of “Knowledge.” For purposes of the Loan Documents, whenever a representation or warranty is made to Borrower’s knowledge or awareness, to the “best of” Borrower’s knowledge, or with a similar

qualification, knowledge or awareness means the actual knowledge, after reasonable investigation, of the Responsible Officers.

     6 AFFIRMATIVE COVENANTS

     Borrower shall do all of the following:

     6.1 Government Compliance.

          (a) 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 cause a Material Adverse Change. Borrower shall comply, and have each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which could reasonably be expected to cause a Material Adverse Change.

          (b) Obtain all of the Governmental Approvals necessary for the performance by Borrower of its obligations under the Loan Documents to which it is a party and the grant of a security interest to Bank in all of its property. At Bank’s request, Borrower shall promptly provide copies of any such obtained Governmental Approvals to Bank.

     6.2 Financial Statements, Reports, Certificates.

          (a) Borrower shall provide Bank with the following:

	(i)		a Transaction Report (and any schedules related thereto) (y) weekly and at the time of each request for an Advance if a Streamline Period is not in effect or an Event of Default has occurred and is continuing, and (z) within thirty (30) days after the end of each month if a Streamline Period is in effect and no Event of Default has occurred and is continuing;
	(ii)		within thirty (30) days after the end of each month,

	(v)		[Reserved];
	(vi)		within thirty (30) days after the beginning of each fiscal year of Borrower, (A) annual operating budgets (including income statements, balance sheets and cash

flow statements, by month) for such fiscal year of Borrower, and (B) annual financial projections for such fiscal year (on a quarterly basis), as approved by Borrower’s board of directors, together with any related business forecasts used in the preparation of such annual financial projections; and

(vii)

as soon as available, and in any event within 90 days following the end of Borrower’s fiscal year, annual financial statements certified by, and with an unqualified opinion of, independent certified public accountants acceptable to Bank, except that the opinion may be qualified for uncertainty of the Borrower’s ability to continue as a going concern.

          (b) At all times that Borrower is subject to the reporting requirements under the Securities Exchange Act of 1934, as amended, within five (5) days after filing, all reports on Form 10-K, l0-Q and 8-K filed with the Securities and Exchange Commission or a link thereto on Borrower’s or another website on the Internet.

          (c) Prompt written notice of (i) any material change in the composition of the Intellectual Property, (ii) the registration of any Copyright, including any subsequent ownership right of Borrower in or to any Copyright, Patent or Trademark not previously disclosed to Bank in writing, or (iii) Borrower’s knowledge of an event that materially adversely affects the value of the Intellectual Property.

          (d) Prompt written report of any legal action pending or threatened in writing against Borrower or any of its Subsidiaries that could result in damages or costs to Borrower or any of its Subsidiaries of more than Two Hundred Fifty Thousand Dollars ($250,000), individually or when aggregated with all other legal actions pending or threatened in writing against Borrower or any of its Subsidiaries that have not previously been disclosed to Bank pursuant to the Perfection Certificate or other written report.

          (e) Other financial information reasonably requested by Bank.

     6.3 Accounts Receivable.

          (a) Schedules and Documents Relating to Accounts. Borrower shall deliver to Bank Transaction Reports and schedules of collections, as provided in Section 6.2, on Bank’s standard forms; provided, however, that Borrower’s failure to execute and deliver the same shall not affect or limit Bank’s Lien and other rights in all of Borrower’s Accounts, nor shall Bank’s failure to advance or lend against a specific Account affect or limit Bank’s Lien and other rights therein. If requested by Bank, Borrower shall furnish Bank with copies (or, at Bank’s request, originals) of all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Accounts. In addition, Borrower shall deliver to Bank, on its request, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary endorsements, and copies of all credit memos.

          (b) Disputes. Borrower shall promptly notify Bank of all disputes or claims relating to Accounts. Borrower may forgive (completely or partially), compromise, or settle any Account for less than payment in full, or agree to do any of the foregoing so long as (i) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, in arm’s-length transactions, and reports the same to Bank in the regular reports provided to Bank; and (ii) no Default or Event of Default has occurred and is continuing; and (iii) after taking into account all such discounts, settlements and forgiveness, no Credit Extension(s) shall exceed any limit thereon contained herein.

          (c) Collection of Accounts. Until payment in full in cash of all Advances and all other Obligations relating to the Revolving Line (other than inchoate indemnity obligations) and Bank’s obligations to make Advances and any other Credit Extensions relating to the Revolving Line have terminated (provided that Borrower’s obligation under this sentence shall not end at a time when any Event of Default exists), Borrower shall be a party to a three party agreement (the “Lockbox Agreement”) with Bank and a lockbox provider (the “Lockbox Provider”). The Lockbox Agreement and Lockbox Provider shall be acceptable to Bank. Borrower shall use the lockbox address as the payment address on all invoices issued by Borrower and shall direct all its Account Debtors

to remit their payments to the lockbox address. The Lockbox Agreement shall provide that the Lockbox Provider shall remit all collections received in the lockbox to Bank. Upon Bank’s receipt of such collections, Bank shall apply the same as follows:

	(i)		If a Streamline Period is in effect, Bank shall deposit such proceeds into the operating account of Borrower at Bank that has been designated by Borrower; and
	(ii)		If a Streamline Period is not in effect, Bank shall apply such proceeds to the outstanding Advances, and if all outstanding Advances have been paid in full, Bank shall deposit the remainder into the operating account of Borrower at Bank that has been designated by Borrower; and
	(iii)		If a Default or Event of Default has occurred and is continuing, without limiting Bank’s other rights and remedies, Bank shall have the right to apply such proceeds to the outstanding Obligations in such order as it shall determine in its discretion.

It is understood and agreed by Borrower that this Section does not impose any affirmative duty on Bank to do any act other than to turn over such amounts. Without limitation on the foregoing, whether or not an Event of Default has occurred and is continuing, Borrower shall immediately deliver all payments on and proceeds of Accounts to an account maintained with Bank to be applied (i) prior to an Event of Default, pursuant to the terms of Section 2.5(b) hereof, and (ii) after the occurrence and during the continuance of an Event of Default, pursuant to the terms of Section 9.4 hereof.

          (d) Returns. Provided no Event of Default has occurred and is continuing, if any Account Debtor returns any Inventory to Borrower, Borrower shall promptly (i) determine the reason for such return, (ii) issue a credit memorandum to the Account Debtor in the appropriate amount, and (iii) provide a copy of such credit memorandum to Bank, upon request from Bank. In the event any attempted return occurs after the occurrence and during the continuance of any Event of Default, Borrower shall immediately notify Bank of the return of the Inventory.

          (e) Verification. Bank may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts, either in the name of Borrower or Bank or such other name as Bank may choose.

          (f) No Liability. Bank shall not be responsible or liable for any shortage or discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any Account, or for settling any Account in good faith for less than the full amount thereof, nor shall Bank be deemed to be responsible for any of Borrower’s obligations under any contract or agreement giving rise to an Account. Nothing herein shall, however, relieve Bank from liability for its own gross negligence or willful misconduct.

     6.4 Remittance of Proceeds. Except as otherwise provided in Section 6.3(c), deliver, in kind, all proceeds arising from the disposition of any Collateral to Bank in the original form in which received by Borrower not later than the following Business Day after receipt by Borrower, to be applied to the Obligations pursuant to the terms of this Agreement; provided that, if no Default or Event of Default has occurred and is continuing, Borrower shall not be obligated to remit to Bank the proceeds of (a) the sale of surplus, worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $25,000 or less (for all such transactions in any fiscal year), or (b) the disposition of marketable securities that are held with or managed by Bank or Bank’s Affiliates, provided that if such proceeds are to be moved from the account in which the marketable securities were held immediately prior to such disposition, they are only moved to an operating account of Borrower with Bank for use thereafter in the ordinary course of Borrower’s business. Borrower agrees

that it will maintain all proceeds of Collateral in an account maintained with Bank. Nothing in this Section limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement.

     6.5 Taxes; Pensions. Timely file, and require each of its Subsidiaries to timely file, all required tax returns and reports, and timely pay, and require each of its Subsidiaries to timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower and each of its Subsidiaries, except for deferred payment of any taxes contested pursuant to the terms of Section 5.9 hereof, and shall deliver to Bank, on demand, appropriate certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms.

     6.6 Access to Collateral; Books and Records. At reasonable times, on five (5) Business Day’s notice (provided no notice is required if an Event of Default has occurred and is continuing), Bank, or its agents, shall have the right to inspect the Collateral and the right to audit and copy Borrower’s Books. The foregoing inspections and audits shall be at Borrower’s expense, and the charge therefor shall be $850 per person per day (or such higher amount as shall represent Bank’s then-current standard charge for the same), plus reasonable out-of- pocket expenses. In the event Borrower and Bank schedule an audit more than ten (10) days in advance, and Borrower cancels or seeks to reschedules the audit with less than ten (10) days written notice to Bank, then (without limiting any of Bank’s rights or remedies), Borrower shall pay Bank a fee of $1,000 plus any out-of-pocket expenses incurred by Bank to compensate Bank for the anticipated costs and expenses of the cancellation or rescheduling.

     6.7 Insurance. Keep its business and the Collateral insured for risks and in amounts standard for companies in Borrower’s industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement showing Bank as an additional lender loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or the loss payable and additional insured endorsements) shall provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any policy shall, at Bank’s option, be payable to Bank on account of the Obligations. Notwithstanding the foregoing, (a) so long as no Event of Default has occurred and is continuing, Borrower shall have the option of applying the proceeds of any casualty policy up to Fifty Thousand Dollars ($50,000) with respect to any loss, but not exceeding One Hundred Thousand Dollars ($100,000) in the aggregate for all losses under all casualty policies in any one year, toward the replacement or repair of destroyed or damaged property; provided that any such replaced or repaired property (i) shall be of equal or 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) 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 6.7 or to pay any amount or furnish any required proof of payment to third persons and Bank, Bank may make all or part of such payment or obtain such insurance policies required in this Section 6.7, and take any action under the policies Bank deems prudent.

     6.8 Operating Accounts.

          (a) Maintain all of its and all of its Subsidiaries’ operating and other deposit accounts, securities accounts, and any other accounts at which Borrower or its Subsidiaries maintain funds or investments (including without limitation any Collateral Accounts, but excluding the Auction Rate Securities (UBS)) with Bank and Bank’s Affiliates.

          (b) Without limitation on subsection “a” above, (i) provide Bank five (5) days prior written notice before establishing any Collateral Account at or with any bank or financial institution other than Bank or Bank’s Affiliates, and (ii) for each Collateral Account that Borrower at any time maintains, Borrower shall cause the applicable bank or financial institution (other than Bank) at or with which any Collateral Account is maintained to execute and deliver a Control Agreement or other appropriate instrument with respect to such Collateral Account to perfect Bank’s Lien in such Collateral Account in accordance with the terms hereunder. The provisions of “ii” of the previous sentence shall not apply to (y) deposit accounts exclusively used for payroll, payroll taxes and other

employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such, or (z) the Auction Rate Securities (UBS).

     6.9 Financial Covenants. Borrower shall maintain at all times, to be tested as of the last day of each month, unless otherwise noted, on a consolidated basis:

          (a) Liquidity Ratio. A Liquidity Ratio of greater than 1.50 to 1.00, to be tested as of the last day of each month during which any Advances were outstanding. In addition, if, at the time an Advance is requested by the Borrower, the Liquidity Ratio has not been tested with respect to the monthly financial statements of Borrower most recently received by Bank, then the Liquidity Ratio shall be tested with respect to such financial statements prior to the Advance being made.

          (b) EBITDA. Maintain EBITDA as of the last day of each month, for the three month period ending as of last day of such month, of at least the following for each such period ending during the following intervals:

		Minimum EBITDA
Interval		(Amounts are Negative)
Effective Date through March 31, 2010			[$7,800,000]
April 1,2010 through June 30, 2010			[$6,500,000]
July 1, 2010 through September 30, 2010			[$5,700,000]
October 1,2010 through December 31, 2010			[$4,300,000]
January 1,2011 through March 31, 2011			[$3,400,000]
April 1,2011 and thereafter			[$2,000,000]

          (c) Fixed Charge Coverage Ratio. A Fixed Charge Coverage Ratio of greater than 1.25 to 1.00, to be tested as of the last day of each month, provided that Borrower shall not be required to maintain the foregoing Fixed Charge Coverage Ratio until on and after the date that the Partial Term Loan Reserve becomes zero.

          (d) Waiver Regarding Performance to Plan Covenant. Reference is made to the fact that the Section 6.9(b) of the Prior LSA contained a requirement that Borrower’s monthly net revenue equal or exceed certain projections and that Borrower failed to satisfy’ such requirements with respect to December 2009, January 2010, February, 2010 and March, 2010 (if the Effective Date is after March 31, 2010). Bank hereby waives any Default or Event of Default that may have occurred as a result of such failure.

     6.10 Intellectual Property Rights.

          (a) (i) Protect, defend and maintain the validity and enforceability of its Intellectual Property; (ii) promptly advise Bank in writing of material infringements of its Intellectual Property; and (iii) not allow any Intellectual Property material to Borrower’s business to be abandoned, forfeited or dedicated to the public without Bank’s written consent.

          (b) Provide written notice to Bank within ten (10) days of entering or becoming bound by any Restricted License (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 (i) any Restricted License 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 Restricted License, whether now existing or entered into in the future, and (ii) Bank to have the ability in the event of a liquidation of any Collateral to dispose of such Collateral in accordance with Bank’s rights and remedies under this Agreement and the other Loan Documents.

          (c) If Borrower (i) obtains any Patent, registered Trademark, registered Copyright, registered mask work, or any pending application for any of the foregoing, whether as owner, licensee or otherwise, or (ii) applies for any Patent or the registration of any Trademark, then Borrower shall immediately provide written notice thereof to Bank and shall execute such intellectual property security agreements and other documents and take such other actions as Bank shall request in its good faith business judgment to perfect and maintain a perfected security interest in favor of Bank in such property subject to senior Permitted Liens. If Borrower decides to register any Copyrights or mask works in the United States Copyright Office, Borrower shall: (x) provide Bank with at least fifteen (15) days prior written notice of Borrower’s intent to register such Copyrights or mask works together with a copy of the application it intends to file with the United States Copyright Office (excluding exhibits thereto); (y) execute an intellectual property security agreement and such other documents and take such other actions as Bank may request in its good faith business judgment to perfect and maintain a perfected security interest in favor of Bank in the Copyrights or mask works intended to be registered with the United States Copyright Office subject only to senior Permitted Liens; and (z) record such intellectual property security agreement with the United States Copyright Office contemporaneously with filing the Copyright or mask work application(s) with the United States Copyright Office. Borrower shall promptly provide to Bank copies of all applications that it files for Patents or for the registration of Trademarks, Copyrights or mask works, together with evidence of the recording of the intellectual property security agreement necessary for Bank to perfect and maintain a perfected security interest in such property subject only to senior Permitted Liens.

     6.11 Litigation Cooperation. From the date hereof and continuing through the termination of this Agreement, make available to Bank, without expense to Bank, Borrower and its officers, employees and agents and Borrower’s books and records, to the extent that Bank may deem them reasonably necessary to prosecute or defend any third-party suit or proceeding instituted by or against Bank with respect to any Collateral or relating to Borrower.

     6.12 Further Assurances. Borrower shall execute any further instruments and take further action as Bank reasonably requests to perfect or continue Bank’s Lien in the Collateral or to effect the purposes of this Agreement.

     7 NEGATIVE COVENANTS

     Borrower shall not do any of the following without Bank’s prior written consent:

     7.1 Dispositions. Convey, sell, lease, transfer, or otherwise dispose of (collectively, “Transfer”), or permit any of its Subsidiaries to Transfer, all or any part of its business or property, except for (a) Transfers of Inventory in the ordinary course of business; (b) Transfers of worn-out or obsolete Equipment; and (c) Transfers consisting of Permitted Liens and Permitted Investments; and (d) Transfers of non-exclusive licenses for the use of the property of Borrower or its Subsidiaries in the ordinary course of business.

     7.2 Changes in Business, Management, Ownership, or Business Locations.

          (a) Engage in or permit any of its Subsidiaries to engage in any business other than the businesses currently engaged in by Borrower and such Subsidiary, as applicable, or reasonably related thereto;

          (b) liquidate or dissolve; or

          (c) permit or suffer any Change in Control; or

          (d) without at least thirty (30) days prior written notice to Bank: (1) add any new offices or business locations, including warehouses (unless such new offices or business locations contain assets and property of Borrower with an aggregate value of less than $10,000) or deliver any portion of the Collateral valued, individually or in the aggregate, in excess of Fifty Thousand Dollars ($50,000) to a bailee at a location other than to a bailee and at a location already disclosed in the Perfection Certificate, (2) change its jurisdiction of organization, (3) change its organizational structure or type, (4) change its legal name, or (5) change its organizational number (if any) assigned by its jurisdiction of organization. If Borrower intends to deliver any portion of the Collateral valued,

individually or in the aggregate, in excess of Fifty Thousand Dollars ($50,000) to a bailee, and Bank and such bailee are not already parties to a bailee agreement governing both the Collateral and the location to which Borrower intends to deliver the Collateral, then Borrower will first receive the written consent of Bank, and such bailee shall execute and deliver a bailee agreement in form and substance satisfactory to Bank in its sole discretion.

     7.3 Mergers or Acquisitions. Merge or consolidate, or permit any of its Subsidiaries to merge or consolidate, with any other Person, or acquire, or permit any of its Subsidiaries to acquire, all or substantially all of the capital stock or property of another Person, except that a Subsidiary of Borrower may merge or consolidate into another Subsidiary of Borrower.

     9 BANK’S RIGHTS AND REMEDIES

     9.1 Rights and Remedies. If an Event of Default has occurred and is continuing, Bank may, without notice or demand, do any or all of the following:

          (a) declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 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) deposit cash with Bank in an amount equal to 105% of the Dollar Equivalent of the aggregate face amount of all Letters of Credit remaining undrawn (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 such Letters of Credit, 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) verify the amount of, demand payment of and performance under, and collect any Accounts and General Intangibles, 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;

          (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, 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 directly with Account Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle, and adjust all claims under any of Borrower’s insurance policies that relate to any of the Collateral; (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 (other than inchoate indemnity 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 (other than inchoate indemnity obligations) have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

     9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.7 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 rate applicable to the Obligations, 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.

     9.4 Application of Payments and Proceeds. Borrower shall have no right to specify the order or the accounts to which Bank shall allocate or apply any payments required to be made by Borrower to Bank or otherwise received by Bank under this Agreement when any such allocation or application is not specified elsewhere in this Agreement. 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. If with respect to any payment or other credit Bank has the right under this Agreement or the other Loan Documents to determine the application of such payment or credit, then Bank may apply and reverse and reapply such payment or credit to the Obligations in such manner as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower by credit to the Designated Deposit Account or to 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.

     9.5 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.

     9.6 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 the party granting the waiver 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 shall not preclude Bank from exercising any other remedy under this Agreement or other remedy available at law or in equity, 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.

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

     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 Santa Clara 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.

TO THE 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.

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 §§ 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 orders 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 § 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.

     12.1 [Reserved].

     12.2 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party.

Bank has the right, without the consent of or notice to Borrower, to sell, transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights, and benefits under this Agreement and the other Loan Documents (other than the Warrant, as to which assignment, transfer and other such actions are governed by the terms of the Warrant).

     12.3 Indemnification. Borrower agrees to indemnify, defend and hold Bank and its directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Bank (each, an “Indemnified Person”) harmless against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) claimed or asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or expenses (including Bank Expenses) in any way suffered, incurred, or paid by such Indemnified Person as a result of, following from, consequential to, or arising from transactions between Bank and Borrower contemplated by the Loan Documents (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct.

     12.4 Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement.

Without limiting the generality of the foregoing, no oral promise or statement, nor any action, inaction, delay, failure to require performance or course of conduct shall operate as, or evidence, an amendment, supplement or waiver or have any other effect on any Loan Document. Any waiver granted shall be limited to the specific circumstance expressly described in it, and shall not apply to any subsequent or other circumstance, whether similar or dissimilar, or give rise to, or evidence, any obligation or commitment to grant any further waiver.

All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied. The obligation of Borrower in Section 12.3 to indemnify the Indemnified Persons shall survive until all statutes of limitation with respect to the Claims, losses and expenses for which indemnity is given shall have run. The provisions of Section 12.10 shall survive termination of this Agreement.

     12.10 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 Subsidiaries or Affiliates (such Subsidiaries and Affiliates, together with Bank, collectively, “Bank Entities”); (b) to prospective transferees or purchasers of any 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; (e) as Bank considers appropriate in exercising remedies under the Loan Documents; and (f) to third-party service providers of Bank so long as such service providers have executed a confidentiality agreement with Bank with terms no less restrictive than those contained herein. Confidential information does not include information that either: (i) is in the public domain or in Bank’s possession when disclosed to Bank, or becomes part of the 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.

     Bank Entities may use the confidential information for reporting purposes and the development and distribution of databases and market analyses so long as such confidential information is aggregated and anonymized prior to distribution unless otherwise expressly prohibited by Borrower. The provisions of the immediately preceding sentence shall survive the termination of this Agreement.

     12.11 Attorneys’ Fees, Costs and Expenses. In any action or proceeding between Borrower and Bank arising out of or relating to the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled.

     12.12 Electronic Execution of Documents. The words “execution,”“signed,”“signature” and words of like import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity and enforceability as a manually executed signature or the use of a paper-based recordkeeping systems, as the case may be, to the extent and as provided for in any applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act.

     12.13 Captions. The headings used in this Agreement are for convenience only and shall not affect the interpretation of this Agreement.

     12.14 Construction of Agreement. The parties mutually acknowledge that they and their attorneys have participated in the preparation and negotiation of this Agreement. In cases of uncertainty this Agreement shall be construed without regard to which of the parties caused the uncertainty to exist.

     12.15 Relationship. The relationship of the parties to this Agreement is determined solely by the provisions of this Agreement. The parties do not intend to create any agency, partnership, joint venture, trust, fiduciary or other relationship with duties or incidents different from those of parties to an arm’s-length contract.
