Exhibit 10.1

SECOND AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT

THIS SECOND AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (this “Agreement”) dated as of the Effective Date by and between SILICON VALLEY BANK, a California corporation with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at One Newton Executive Park, Suite 200, 2221 Washington Street, Newton, Massachusetts 02462 (“Bank”), and IBASIS, INC., a Delaware corporation with offices located at 20 Second Avenue, Burlington, Massachusetts 01803 (“Borrower”), provides the terms on which Bank shall lend to Borrower and Borrower shall repay Bank and amends and restates in its entirety a certain Amended and Restated Loan and Security Agreement dated as of December 29, 2003 entered into by and between Bank and Borrower, as amended. 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, Bank will make Advances to Borrower up to the Availability Amount. Amounts borrowed under the Revolving Line may be repaid, and prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein.

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

2.1.2 Letters of Credit Sublimit.

(a) As part of the Revolving Line, Bank shall issue or have issued Letters of Credit for Borrower’s account. The face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) may not exceed $10,000,000 inclusive of Credit Extensions relating to Sections 2.1.3 and 2.1.4. In accordance with the definition of Availability Amount, 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 good faith business judgment), to secure all of the Obligations relating to said Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank’s standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request. 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 good faith interpretations of any Letter of Credit issued by Bank for Borrower’s account (provided such interpretation is not manifestly erroneous), 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 proper 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 (the “FX Reserve”). The aggregate amount of the FX Reserve at any one time plus Credit Extensions relating to Sections 2.1.2 and 2.1.4 may not exceed Ten Million Dollars ($10,000,000.00). In accordance with the definition of Availability Amount, the amount otherwise available for Credit Extensions under the Revolving Line shall be reduced by the aggregate amount of all FX Reserves. Any amounts due and unpaid under an FX Forward Contract 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 Ten Million Dollars ($10,000,000.00) inclusive of Credit Extensions relating to Sections 2.1.2 and 2.1.3 (the “Cash Management Services Sublimit”) 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”). In accordance with the definition of Availability Amount, the dollar amount of any Cash Management Services provided under this sublimit will reduce the amount otherwise available under the Revolving Line. Any amounts owed to Bank which are due and unpaid from 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 or for any reason the total of all outstanding Advances and all other monetary Obligations exceeds the Availability Amount (an “Overadvance”), Borrower shall immediately pay the amount of the excess to Bank, without notice or demand. Without limiting Borrower’s obligation to repay to Bank the amount of any Overadvance, Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance, on demand, at the Default Rate.

2.3 General Provisions Relating to the Advances. Each Advance shall, at Borrower’s option in accordance with the terms of this Agreement, be either in the form of a Prime Rate Advance or a LIBOR Advance; provided that in no event shall Borrower maintain at any time LIBOR Advances having more than four (4) different Interest Periods. Borrower shall pay interest accrued on the Advances at the rates and in the manner set forth in Section 2.4(a).

2.4 Payment of Interest on the Credit Extensions.

(a) Advances. Each Advance shall bear interest on the outstanding principal amount thereof from the date when made, continued or converted until paid in full at a rate per annum equal to (i) the Prime Rate plus the applicable Prime Rate Margin or (ii) the LIBOR Rate plus the applicable LIBOR Rate Margin. Pursuant to the terms hereof, interest on each Advance shall be paid in arrears on each Interest Payment Date. Interest shall also be paid on the date of any prepayment of any Advance pursuant to this Agreement for the portion of any Advance so prepaid and upon payment (including prepayment) in full thereof. All accrued but unpaid interest on the Advances shall be due and payable on the Revolving Line Maturity Date.

(b) Performance Pricing. Each of the Prime Rate Margin and the LIBOR Rate Margin shall be adjusted quarterly and shall be applied on and after the first day of each such fiscal quarter as follows: for any fiscal quarter, as of the first day of each such fiscal quarter: (i) if the Total Funded Debt Ratio for the immediately preceding fiscal quarter is less than 1.50:1.00, then the Prime Rate Margin for such fiscal quarter shall be 0.00% and the LIBOR Rate Margin for such fiscal quarter shall be 2.25%, and (ii) if the Total Funded Debt Ratio for the immediately preceding fiscal quarter is equal to or greater than 1.50:1.00, then the Prime Rate Margin for such fiscal quarter shall be 0.50% and the LIBOR Rate Margin for such fiscal quarter shall be 2.75%.

(c) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, the Obligations shall bear interest at a rate per annum which is five 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 2.4(c) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Bank.

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

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

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

(g) Debit of Accounts. Bank may debit the Designated Deposit Account and account nos. 3300372126, 3300381409 and 3300498404 maintained at Bank, for principal and interest payments or, after notice to Borrower, any other amounts Borrower owes Bank when due. These debits shall not constitute a set-off.

(h) Payment; Interest Computation; Float Charge. In computing interest on the Credit Extensions, all Payments received after 12:00 p.m. Pacific time on any day shall be deemed received on the next Business Day. Bank may charge Borrower’s Designated Deposit Account for the amount of any item of payment which is returned to Bank unpaid.

2.5 Fees. Borrower shall pay to Bank:

(a) Facility Fee. A fully earned, non-refundable facility fee of $262,500, on or before 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 or renewal of such Letter of Credit by Bank, which fees and expenses shall not exceed 1.25% per annum of the face amount of such Letter of Credit plus expenses;

(c) Termination Fee. Subject to the terms of Section 4.1, a termination fee;

(d) Unused Revolving Line Facility Fee. A fee (the “Unused Revolving Line Facility Fee”), which fee shall be paid quarterly, in arrears, on the last day of each fiscal quarter, calculated as follows: (i) if the Total Funded Debt Ratio for the fiscal quarter for which the Unused Revolving Line Facility Fee is due is less than 1.50:1.00, the Unused Revolving Line Facility Fee for such fiscal quarter shall be 0.375% per annum of the average unused portion of the Revolving Line for such quarter, as determined by Bank; and (ii) if the Total Funded Debt Ratio for the fiscal quarter for which the Unused Revolving Line Facility Fee is due is greater than or equal to 1.50:1.00, the Unused Revolving Line Facility Fee for such fiscal quarter shall be 0.625% per annum of the average unused portion of the Revolving Line for such quarter, 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 2.5(d) notwithstanding any suspension or termination of Bank’s obligation to make Advances hereunder; and

(e) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses for documentation and negotiation of this Agreement) incurred through and after the Effective Date, when due.

3.1 Conditions Precedent to Initial Credit Extension. Bank’s obligation to make the initial Credit Extension is subject to the condition precedent that Bank shall have received, in form and substance satisfactory to Bank, such documents, and completion of such other matters, as Bank may reasonably deem necessary or appropriate, including, without limitation:

3.3 Covenant to Deliver.

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

3.4 Procedures for Borrowing.

(a) Subject to the prior satisfaction of all other applicable conditions to the making of an Advance set forth in this Agreement, each Advance shall be made upon Borrower’s irrevocable written notice delivered to Bank in the form of a Notice of Borrowing, each executed by a Responsible Officer of Borrower or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Bank shall credit Advances to the Designated Deposit Account. Bank may rely on any telephone notice given by a person whom Bank reasonably believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance. Such Notice of Borrowing must be received by Bank prior to 11:00 a.m. Pacific time (i) on the same day as the requested Funding Date, in the case of Prime Rate Advances, and (ii) at least two (2) Business Days prior to the requested Funding Date, in the case of LIBOR Advances, specifying:

(1) the amount of the Advance, which, if a LIBOR Advance is requested, shall be in an aggregate minimum principal amount of $500,000 or in any integral multiple of $500,000 in excess thereof;

(2) the requested Funding Date; and

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

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

3.5 Conversion and Continuation Elections.

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

(1) elect to convert on any Business Day, Prime Rate Advances in an amount equal to $500,000 or any integral multiple of $500,000 in excess thereof into LIBOR Advances;

(2) elect to continue on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date (or any part thereof in an amount equal to $500,000 or any integral multiple of $500,000 in excess thereof); provided, that if the aggregate amount of LIBOR Advances shall have been reduced, by payment, prepayment, or conversion of part thereof, to be less than $500,000, such LIBOR

Advances shall automatically convert into Prime Rate Advances, and on and after such date the right of Borrower to continue such Advances as, and convert such Advances into, LIBOR Advances shall terminate; or

(3) elect to convert on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date (or any part thereof in an amount equal to $500,000 or any integral multiple of $500,000 in excess thereof) into Prime Rate Advances.

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

(1) proposed Conversion Date or Continuation Date; and

(2) aggregate amount of the Advances to be converted or continued which, if any Advances are to be converted into or continued as LIBOR Advances, shall be in an aggregate minimum principal amount of $1,000,000 or in any integral multiple of $500,000 in excess thereof.

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

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

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

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

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

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

(c) Compensation for Breakage or Non-Commencement of Interest Periods. Borrower shall compensate Bank, upon written request by Bank (which request shall set forth the manner and method of computing such compensation), for all reasonable losses, expenses and liabilities, if any (including any interest paid by Bank to lenders of funds borrowed by it to make or carry its LIBOR Advances and any loss, expense or liability incurred by Bank in connection with the liquidation or re-employment of such funds) such that Bank may incur: (i) if for any reason (other than a default by Bank or due to any failure of Bank to fund LIBOR Advances due to impracticability or illegality under Sections 3.7(d) and 3.7(e)) a borrowing or a conversion to or continuation of any LIBOR Advance does not occur on a date specified in a Notice of Borrowing or a Notice of Conversion/Continuation, as the case may be, or (ii) if any principal payment or any conversion of any of its LIBOR Advances occurs on a date prior to the last day of an Interest Period applicable to that Advance.

(d) Assumptions Concerning Funding of LIBOR Advances. Calculation of all amounts payable to Bank under this Section 3.6 and under Section 3.4 shall be made as though Bank had actually funded each of its relevant LIBOR Advances through the purchase of a Eurodollar deposit bearing interest at the rate obtained pursuant to the definition of LIBOR Rate in an amount equal to the amount of such LIBOR Advance and having a maturity comparable to the relevant Interest Period; provided, however, that Bank may fund each of its LIBOR Advances in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 3.6 and under Section 3.4.

(e) LIBOR Advances After Default. After the occurrence and during the continuance of an Event of Default, (i) Borrower may not elect to have an Advance be made or continued as, or converted to, a LIBOR Advance after the expiration of any Interest Period then in effect for such Advance and (ii) subject to the provisions of Section 3.6(c), any Notice of Conversion/Continuation given by Borrower with respect to a requested conversion/continuation that has not yet occurred shall be deemed to be rescinded by Borrower and be deemed a request to convert or continue Advances referred to therein as Prime Rate Advances.

3.7 Additional Requirements/Provisions Regarding LIBOR Advances.

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

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

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

(2) imposes or modifies any reserve, special deposit or similar requirements relating to any Credit Extensions based upon a LIBOR Rate; or

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

Bank will notify Borrower of any event occurring after the Effective Date which will entitle Bank to compensation pursuant to this Section 3.7 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Bank will furnish Borrower with a statement setting forth the basis and amount of each request by Bank for compensation under this Section 3.7. Determinations and allocations by Bank for purposes of this Section 3.7 of the effect of any Regulatory Change on its costs of maintaining its obligations to

make Advances, of making or maintaining Advances, or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate Bank in respect of any Additional Costs, shall be conclusive absent manifest error.

(c) If Bank shall reasonably determine that the adoption or implementation of any applicable law, rule, regulation, or treaty regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by Bank (or its applicable lending office) with any respect or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on capital of Bank or any person or entity controlling Bank (a “Parent”) as a consequence of its obligations hereunder to a level below that which Bank (or its Parent) could have achieved but for such adoption, change, or compliance (taking into consideration policies with respect to capital adequacy) by an amount deemed by Bank to be material, then from time to time, within fifteen (15) days after demand by Bank, Borrower shall pay to Bank such additional amount or amounts as will compensate Bank for such reduction. A statement of Bank claiming compensation under this Section 3.7(c) and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error.

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

(e) If it shall become unlawful for Bank to continue to fund or maintain any LIBOR Advances, or to perform its obligations hereunder, upon demand by Bank, Borrower shall prepay the Advances in full with accrued interest thereon and all other amounts payable by Borrower hereunder (including, without limitation, any amount payable in connection with such prepayment pursuant to Section 3.7(a)). Notwithstanding the foregoing, to the extent a determination by Bank as described above relates to a LIBOR Advance then being requested by Borrower pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, Borrower shall have the option, subject to the provisions of Section 3.6(c), to (i) rescind such Notice of Borrowing or Notice of Conversion/Continuation by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such rescission on the date on which Bank gives notice of its determination as described above, or (ii) modify such Notice of Borrowing or Notice of Conversion/Continuation to obtain a Prime Rate Advance or to have outstanding Advances converted into or continued as Prime Rate Advances by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such modification on the date on which Bank gives notice of its determination as described above.

4 CREATION OF SECURITY INTEREST

4.1 Grant of Security Interest.

(a) Borrower hereby grants Bank, to secure the payment and performance in full of all of the Obligations, a continuing security interest in, pledges and charges by way of security, 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 material 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.

(b) Borrower hereby ratifies that certain Intellectual Property Security Agreement, dated as of December 30, 2002 by and among by and Borrower and Lender, and such Intellectual Property Security Agreement remains in full force and effect.

(c) This Agreement may be terminated prior to the Revolving Line Maturity Date by Borrower, effective three (3) Business Days after written notice of termination is given to Bank. Notwithstanding any such termination, Bank’s lien and security interest in the Collateral shall continue until Borrower fully satisfies its Obligations arising out of the Loan Documents. If such termination is at Borrower’s election or at Bank’s

election due to the occurrence and continuance of an Event of Default, Borrower shall 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) for any termination within six (6) months of the Effective Date, one percent (1%) of $35,000,000, and (ii) for any termination during the period from six (6) months after the Effective Date up to but not including the first anniversary of the Effective Date, one-half of one percent (0.50%) of $35,000,000, provided that no termination fee shall be charged if (i) the credit facility hereunder is replaced with a new facility from Silicon Valley Bank, (ii) the credit facility hereunder is terminated for any reason after the first anniversary of the Effective Date, or (iii) the credit facility hereunder is terminated by Borrower solely as a result of Bank’s determination to no longer offer LIBOR Advances pursuant to the provisions of Sections 3.6(b) or 3.7(d). Upon payment in full of the Obligations and at such time as Bank’s obligation to make Credit Extensions has terminated, Bank shall release its liens and security interests in the Collateral and all rights therein shall revert to Borrower and each Guarantor, as applicable.

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 by Bank to violate the rights of Bank under the Code. Without limiting the foregoing, Borrower hereby authorizes Bank to file financing statements which describe the Collateral as “all assets” and/or “all personal property” of Borrower or words of similar import.

5 REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants as follows:

5.1 Due Organization and Authorization. Borrower and each of its Subsidiaries are duly existing and in good standing 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 and each Guarantor have delivered to Bank a completed certificate substantially in the form attached hereto as Exhibit C signed by Borrower and each Guarantor, as applicable, entitled “Perfection Certificate”. Borrower represents and warrants to Bank that (a) Borrower’s and each Guarantor’s exact legal name is that indicated on the applicable Perfection Certificate and, in the case of the Borrower, on the signature page hereof; (b) Borrower and each Guarantor is an organization of the type and is organized in the jurisdiction set forth in the applicable Perfection Certificate; (c) each applicable Perfection Certificate accurately sets forth Borrower’s and each Guarantor’s organizational identification number or accurately states that Borrower or such Guarantor has none; (d) each applicable Perfection Certificate accurately sets forth Borrower’s and each Guarantor’s place of business, or, if more than one, each chief executive office as well as Borrower’s and each Guarantor’s mailing address (if different than its chief executive office); (e) Borrower, each Guarantor (and each of their 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 each Perfection Certificate pertaining to Borrower and each Guarantor is accurate and complete. If Borrower or any Guarantor is not now a Registered Organization but later becomes one, Borrower or such Guarantor, as the case may be, shall promptly notify Bank of such occurrence and provide Bank with Borrower’s or such Guarantor’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.

5.2 Collateral. Borrower has good title to, has rights in, and the power to transfer each item of Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. Borrower and each Guarantor have no Deposit Accounts other than the Deposit Accounts with Bank and Deposit Accounts described in the applicable Perfection Certificate delivered to Bank in connection herewith.

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the applicable Perfection Certificate. None of the material components of the Collateral are maintained at locations other than as provided in the applicable Perfection Certificate unless Borrower has notified Bank of such other locations. In the event that Borrower or any Guarantor, after the date hereof, intends to store or otherwise deliver any material 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 and each Guarantor is a licensee or the sole owner of its respective intellectual property, except for non-exclusive licenses granted to Affiliates or its customers in the ordinary course of business. To Borrower’s knowledge, each patent is valid and enforceable and no part of the intellectual property has been judged invalid or unenforceable, in whole or in part, and to the best of Borrower’s knowledge, no claim has been made that any part of the intellectual property owned by Borrower violates the rights of any third party.

Except as disclosed to Bank in writing, neither Borrower nor any Guarantor is a party to, nor is bound by, any license or other agreement with respect to which Borrower or any Guarantor is the licensee that prohibits or otherwise restricts Borrower or such Guarantor from granting a security interest in Borrower’s or such Guarantor’s interest in such license or agreement or any other property.

5.3 Accounts Receivable.

(a) For each Account with respect to which Advances are requested, on the date each Advance is requested and made, such Account shall meet the minimum eligibility requirements set forth in the definition of “Eligible Accounts” in Section 13 below.

(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 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 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 in Borrower’s Perfection Certificate, 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 in which an adverse decision could reasonably be expected to cause a Material Adverse Change.

5.5 No Material Deviation in Financial Statements. All consolidated and consolidating 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” nor a company “controlled” by an “investment company” under the Investment Company Act. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations T and U of the Federal Reserve Board of Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to have a Material Adverse Change 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 provided that 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, and (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 material 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 (i) working capital, (ii) to fund its general business requirements and (iii) to fund dividends declared by the Borrower in connection with a transaction in which, among other things, KPN, B.V. will become the owner of 51% of the equity of the Borrower, 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 representations, warranties, or other statements were made, taken together with all such written certificates and written statements given to Bank, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results).

6.3 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; 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 commercially reasonable 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 commercially reasonable 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 material 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; (ii) no Default or Event of Default has occurred and is continuing; and (iii) after taking into account all such discounts, settlements and forgiveness, the total outstanding Advances will not exceed the Availability Amount.

(c) Collection of Accounts. Borrower shall have the right to collect all Accounts, unless and until a Default or an Event of Default has occurred and is continuing. Accounts shall be deposited by Borrower into a lockbox account, or such other “blocked account” as Bank may specify, pursuant to a blocked account agreement in such form as Bank may specify in its good faith business judgment. Whether or not an Event of Default has occurred and is continuing, Borrower shall hold all Payments on, and proceeds of, Accounts in trust for Bank, and Borrower shall immediately deliver all such payments and proceeds to Bank in their original form, duly endorsed, to be applied to the Obligations pursuant to the terms of Section 9.4 hereof, provided, however, in the event no Default or Event of Default has occurred and is continuing and Borrower maintains unrestricted cash and Cash Equivalents at Bank plus the Availability Amount under the Revolving Line of no less than $15,000,000, all Payments on, and proceeds of, Accounts shall be transferred by Bank to an operating account of Borrower maintained at Bank.

(d) 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. Such verification shall be accomplished in a commercially reasonable manner.

(e) 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 Section 9.4 hereof; 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 the sale of worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $500,000 or less (for all such transactions in any fiscal year). Borrower agrees that it will not commingle proceeds of Collateral with any of Borrower’s other funds or property, but will hold such proceeds separate and apart from such other funds and property and in an express trust for Bank. Nothing in this Section 6.4 limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement.

6.5 Taxes; Pensions. Make, and cause each of its Subsidiaries, if any, to make, timely payment of all foreign, federal, state and local taxes or assessments (other than taxes and assessment which Borrower is contesting 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 provided that 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”.

6.6 Access to Collateral; Books and Records; Field Exam. At reasonable times, on three (3) 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 $750 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, but the total amount of any such audit shall not exceed $7,500 plus reasonable out-of-pocket expenses. Absent the occurrence of an Event of Default, no more than one such inspection or audit may occur in any fiscal quarter. In the event Borrower and Bank schedule an audit more than ten (10) days in advance, and Borrower cancels or seeks to reschedule 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. The first such inspection and audit shall be scheduled to occur with sixty (60) days of the Effective Date.

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 reasonably satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement showing Bank as the sole 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 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 $1,000,000, in the aggregate, 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, in its business judgment.

6.8 Operating Accounts.

(a) Maintain its and its Domestic Subsidiaries’ primary depository, operating accounts and securities accounts with Bank and Bank’s affiliates with all excess funds maintained at or invested through Bank or an affiliate of Bank. Any Guarantor shall maintain all depository, operating and securities accounts with Bank, or with an Affiliate of Bank, provided, however, KPN International Network Services, Inc. shall have three (3) months from the Effective Date to close, transfer or provide a Control Agreement satisfactory to Bank with respect to any of its accounts that are not maintained with Bank as of the Effective Date.

(b) 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 its Affiliates. In addition, 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 the previous sentence shall not apply to 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.

6.9 Financial Covenants.

Borrower shall maintain at all times, to be tested as of the last day of each quarter, unless otherwise noted:

(i) Adjusted Quick Ratio. On a consolidated basis, a ratio of Quick Assets to Current Liabilities minus Deferred Revenue of not less than the following amounts

Period		Minimum Adjusted Quick Ratio

Effective Date through March 31, 2008		0.75:1.00

April 1, 2008 through December 31, 2008		0.85:1.00

Thereafter		1.00:1.00

(ii) Consolidated EBITDA. Maintain, calculated on a consolidated basis with each of its Subsidiaries, measured as of the end of each fiscal quarter, EBITDA of at least $10,000,000.

(iii) Borrower EBITDA. For any fiscal quarter in which unrestricted cash and Cash Equivalents maintained at Bank plus the Availability Amount under the Revolving Line is less than $15,000,0000, Borrower shall maintain, calculated on a consolidated basis with its Existing Domestic Subsidiaries, EBITDA of at least (I) for the fiscal quarter ending December 31, 2007 $1.00 and (II) $2,000,000 for each such fiscal quarter thereafter.

Notwithstanding anything in this Section 6.9 to the contrary, and provided an Event of Default has not occurred and is not continuing, if at any time the Borrower is in violation of any one or more of the provisions of this Section 6.9, and prior to the applicable financial statement reporting deadline of Section 6.2 for which such violation occurs the Borrower receives unrestricted cash proceeds from the issuance of Capital Stock, then such proceeds shall be added to the numerator of the Adjusted Quick Ratio set forth in Section 6.9(i) and to EBITDA in Sections 6.9(ii) and (iii) in connection with the calculation of the applicable financial covenant described herein in such fiscal quarter.

6.10 Protection and Registration of Intellectual Property Rights. Borrower shall: (a) protect, defend and maintain the validity and enforceability of its material intellectual property; (b) promptly advise Bank in

writing of material infringements of its intellectual property; and (c) not allow any intellectual property material to Borrower’s business to be abandoned, forfeited or dedicated to the public without Bank’s written consent. If Borrower or any Guarantor decides to register any copyrights or mask works in the United States Copyright Office, Borrower shall, and shall cause such Guarantor to: (x) provide Bank with at least fifteen (15) days prior written notice of its 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 IP Security Agreement or such other documents as Bank may reasonably request to maintain the perfection and priority of Bank’s security interest in the copyrights or mask works intended to be registered with the United States Copyright Office; and (z) record such IP 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 a copy of the application(s) filed with the United States Copyright Office together with evidence of the recording of the IP Security Agreement necessary for Bank to maintain the perfection and priority of its security interest in such copyrights or mask works. Borrower shall provide written notice to Bank of any application filed by Borrower or any Guarantor in the United States Patent and Trademark Office for a patent or to register a trademark or service mark within 30 days after any such filing.

Borrower shall provide written notice to Bank within ten (10) days of Borrower or any Guarantor entering into or becoming bound by any material license or agreement that prohibits or otherwise restricts Borrower or any Guarantor from granting a security interest in Borrower’s or Guarantor’s interest in such license or agreement (other than over-the-counter software that is commercially available to the public). Borrower shall take such steps as Bank reasonably 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 good faith judgment), whether now existing or entered into in the future; provided, however, that the failure of Borrower to obtain such consent or waiver after taking commercially reasonable steps to do so shall not constitute an Event of Default hereunder.

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.

8.3 Material Adverse Change. A Material Adverse Change occurs;

8.6 Other Agreements. There is an uncured default beyond any grace period in any agreement to which Borrower or any Guarantor is a party with a third party or parties resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of $350,000 or that could have a material adverse effect on Borrower’s or any Guarantor’s business;

8.7 Judgments.

8.8 Misrepresentations. Borrower or any Person acting for Borrower makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Bank or to induce Bank to enter this Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect in any material respect when made;

9 BANK’S RIGHTS AND REMEDIES

9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following:

(a) declare all Obligations immediately due and payable (but if 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 the aggregate amount of any Letters of Credit remaining undrawn, as collateral security for the repayment of any future drawings under such Letters of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of any Letters of Credit;

(d) terminate any FX Contracts;

(e) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that is commercially reasonable and which 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 in its commercially reasonable judgment 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, except to the extent that funds have been set aside by Borrower to pay wages, payroll taxes, or employment benefits earned by employees of the 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) subject to Section 9.1(e), settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Bank determines reasonable; (d) subject to Section 6.7, 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 reasonably necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred until all Obligations have been satisfied in full and Bank is under no further obligation to make Credit Extensions hereunder. Bank’s foregoing appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

9.3 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 applicable rate, and secured by the Collateral. Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such insurance at the time it is obtained or within a reasonable time thereafter; provided that, if an Event of Default is not in existence, Bank shall provide ten (10) days prior written notice to Borrower, during which time Borrower shall be entitled to cure any breach of Section 6.7. 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.

Unless an Event of Default has occurred and is continuing or subject to the terms of Section 6.3(c), Bank shall apply any funds in the Designated Deposit Account and account nos. 3300372126, 3300381409 and 3300498404 maintained at Bank, whether from Borrower account balances, payments, or proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, first, to Bank Expenses, including without limitation, the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Bank in the exercise of its rights under this Agreement; second, to the interest due upon any of the Obligations; and third, to the principal of the Obligations and any applicable fees and other charges, in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If an Event of Default has occurred and is continuing, Bank may apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower or 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. Except as described above, 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 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.

9.7 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.

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 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 the jurisdiction of the State and Federal Courts in Massachusetts 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. NOTWITHSTANDING ANYTHING TO THE CONTRARY SET FORTH HEREINABOVE, BANK SHALL SPECIFICALLY 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.

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

12 GENERAL PROVISIONS

12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations under it without Bank’s prior written consent (which may be granted or withheld in Bank’s discretion).

12.2 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 harmless against (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by Bank to a party other than Borrower or Guarantor from, following, or arising from transactions between Bank and Borrower (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by Bank’s gross negligence or willful misconduct.

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

12.4 Severability of Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision.

12.5 Amendments in Writing; Integration. All amendments to this Agreement must be in writing signed by both Bank and Borrower. This Agreement and the Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement and the Loan Documents merge into this Agreement and the Loan Documents.

12.6 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, are an original, and all taken together, constitute one Agreement.

12.7 Survival. 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 12.2 to indemnify Bank shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

12.8 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; (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; and (e) as Bank considers appropriate in exercising remedies under this Agreement. 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.

12.9 Attorneys’ Fees, Costs and Expenses. In any action or proceeding between Borrower and Bank arising out of or relating to the Loan Documents, Bank 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.

collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank (including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.
