REVOLVING FACILITY AGREEMENT

This REVOLVING FACILITY AGREEMENT (this “Agreement”), dated as of November 14, 2005, is entered into by and among EVOLVING SYSTEMS LTD., a company incorporated under the laws of England & Wales with registration number 2325854 (“Borrower”); EVOLVING SYSTEMS HOLDINGS LTD., a company incorporated under the laws of England & Wales with registration number 5272751 (a “UK Guarantor”), EVOLVING SYSTEMS, INC., a Delaware Corporation, TELECOM SOFTWARE ENTERPRISES, LLC, a Colorado limited liability company and EVOLVING SYSTEMS HOLDINGS, Inc., a Delaware Corporation as Credit Parties; CAPITALSOURCE FINANCE LLC, a Delaware limited liability company (in its individual capacity, “CapitalSource”), as administrative, payment and collateral agent for the Lenders (CapitalSource, in such capacities, “Agent”); CSE FINANCE INC as a Lender, a Delaware corporation (“CSE Finance”); and the Lenders from time to time parties hereto.

WHEREAS, the Credit Parties have requested that Lenders make available to Borrower (i) a revolving credit facility (including a letter of credit sub-facility ) (the “Revolving Facility”) in a maximum aggregate amount not to exceed the Facility Cap in effect from time to time (the amount of which, initially, shall be $4,500,000), shall be used by Borrower for purposes permitted under, and otherwise in accordance with and subject to the terms of, this Agreement.

WHEREAS, Lenders are willing to make the Revolving Facility available to Borrower, upon the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt, sufficiency and adequacy of which hereby are acknowledged, the parties hereto hereby agree as follows:

I. DEFINITIONS

(a) For purposes of the Loan Documents and all schedules, exhibits, annexes and attachments thereto, in addition to the definitions elsewhere in this Agreement and the other Loan Documents, the terms listed in Appendix A hereto shall have the respective meanings assigned to such terms in Appendix A hereto, which is incorporated herein and made a part hereof. All capitalized terms used which are not specifically defined herein shall have the respective meanings assigned to them in Article 9 of the UCC to the extent the same are used or defined therein. Unless otherwise specified in any Loan Document, this Agreement, any other Loan Document and any agreement or contract referred to herein or in Appendix A hereto shall mean such agreement or contract, as modified, amended, supplemented or restated and in effect from time to time, subject to any applicable restrictions set forth in such Loan Document. Unless otherwise specified, as used in the Loan Documents or in any certificate, report, instrument or other document made or delivered pursuant to any of the Loan Documents, all accounting terms not defined in Appendix A hereto or elsewhere in this Agreement or any other Loan Document shall have the meanings assigned to such terms in and shall be interpreted in accordance with GAAP. If any change in GAAP results in a change in the calculation of the financial covenants or interpretation of related provisions of this Agreement or any other Loan Document, then

Borrower, Agent, Lenders and the other Credit Parties agree to amend such provisions of this Agreement so as to equitably reflect such changes in GAAP with the desired result that the criteria for evaluating the Credit Parties’ financial condition shall be the same after such change in GAAP as if such change had not been made, provided that, notwithstanding any other provision of this Agreement, the Requisite Lenders’ agreement to any amendment of such provisions shall be sufficient to bind all Lenders; and, provided further, until such time as the financial covenants and the related provisions of this Agreement have been amended in accordance with the terms of this paragraph, the calculations of financial covenants and the interpretation of any related provisions shall be calculated and interpreted in accordance with GAAP as in effect immediately prior to such change in GAAP.

II. CREDITS

2.1 Revolving Facility

(a) Subject to the terms and conditions set forth in this Agreement, each Lender agrees to make available to Borrower its Pro Rata Share of Advances under the Revolving Facility from time to time during the Term; provided, that (i) the Pro Rata Share of Advances of any Lender shall not at any time exceed such Lender’s Commitment under the Revolving Facility and (ii) the aggregate amount of all Advances at any time outstanding under the Revolving Facility shall not exceed the lesser of (x) the Facility Cap in effect at such time less the Letter of Credit Usage then in effect and (y) the Aggregate Borrowing Availability then in effect. The obligations of the Lenders under the Revolving Facility shall be several, and not joint or joint and several. The Revolving Facility is a revolving credit facility that may be drawn, repaid and redrawn from time to time as permitted under this Agreement. Borrower may not at any time increase, reduce or otherwise adjust the Facility Cap. Agent shall have the right to establish and readjust from time to time, in its Permitted Discretion, reserves under the Revolving Facility, which reserves shall have the effect of reducing the amounts otherwise available to be disbursed to Borrower under the Revolving Facility.

(b) Subject to Section 2.1(a) Borrower shall maintain a minimum outstanding balance at all times of Advances in the amount of at least $2,000,000 from the Closing Date until delivery of the Compliance Certificate for the quarter ending December 31, 2005 and at a variable amount, to be adjusted thereafter following delivery of the Compliance Certificate after the end of each fiscal quarter, as follows:

Leverage Ratio calculated pursuant to Exhibit B-1 as reported on the Compliance Certificate for the 12-month period ending at the end of any fiscal quarter	Minimum Balance of Advances Until the Next Reported Measurement of the Leverage Ratio

Equal to or greater than 1.00 to 1	$	2,000,000

Less than 1.00 to 1 and equal to or greater than .75 to 1	$	1,500,000

Less than .75 to 1 and equal to or greater than .50 to 1	$	1,100,000

Less than .50 to 1 and equal to or greater than .25 to 1	$	700,000

Less than .25 to 1	$	300,000

2.2 Evidence of Loans

(a) Each Lender shall maintain, in accordance with its usual practice, electronic or written records evidencing the indebtedness and obligations to such Lender resulting from each Loan made by such Lender from time to time, including, without limitation, the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(b) Agent shall maintain electronic or written records in which it will record (i) the amount of each Loan made hereunder, the class and type of each Loan made and any applicable interest rate periods, (ii) the amount of any principal and/or interest due and payable and/or to become due and payable from Borrower to each Lender hereunder and (iii) all amounts received by Agent hereunder from Borrower and each Lender’s share thereof.

(c) The entries in the electronic or written records maintained pursuant to Section 2.2(b) (the “Register”), which shall include the promissory notes, if any, issued pursuant to Section 2.2(e) hereof, shall in the absence of manifest error be prima facie evidence of the existence and amounts of the obligations and indebtedness therein recorded; provided, however, that the failure of Agent to maintain such records or any error therein shall not in any manner affect the obligations of Borrower to repay the Loans or Obligations in accordance with their terms. The Register shall be subject to the terms of Section 12.4(c).

(d) Agent will account to Borrower monthly with a statement of Advances under the Revolving Facility and any charges and payments made pursuant to this Agreement, and in the absence of demonstrable error, such accounting rendered by Agent shall be deemed final, binding and conclusive unless Agent is notified by Borrower in writing to the contrary within fifteen (15) calendar days of Receipt of such accounting, which notice shall be deemed an objection only to items specifically objected to therein.

(e) Borrower agrees that:

(i) upon written notice by Agent to Borrower that a promissory note or other evidence of indebtedness or replacement of a lost Note is requested by Agent (for itself or on behalf of any Lender) to evidence the Loans and other Obligations owing or payable to, or to be made by, such Lender, Borrower promptly shall (and in any event within five (5) Business Days of any such request and in the event of a lost Note upon receipt of customary affidavits and indemnities) execute and deliver to Agent an appropriate promissory note or notes in form and substance reasonably satisfactory to Agent and Borrower, payable to the order of such Lender in a principal amount equal to the amount of the Loans owing or payable to such Lender;

(ii) all references to “Notes” in the Loan Documents shall mean Notes, if any, to the extent issued (and not returned to Borrower for cancellation) hereunder, as the same may be amended, supplemented, modified, divided and/or restated and in effect from time to time which shall be included in the Register maintained by the Agent; and

(iii) upon Agent’s written request (for itself or on behalf of any Lender), and in any event within five (5) Business Days of any such request, Borrower shall execute and deliver to Agent new Notes and/or split or divide the Notes, or any of them, in exchange for the then existing subject Notes, in such smaller amounts or denominations as Agent or such Lender shall specify; provided, that the aggregate principal amount of such new, split or divided Notes shall not exceed the aggregate principal amount of the Notes outstanding at the time such request is made; and provided, further, that such Notes that are replaced shall then be deemed no longer outstanding hereunder and replaced by such new Notes, promptly cancelled and returned to Borrower within a reasonable period of time after Agent’s receipt of the replacement Notes.

2.3 Interest

(a) Subject to Section 2.3(c), each Loan shall bear interest on a daily basis on the outstanding principal amount thereof from the date made (each a “Borrowing Date”) at a rate per annum equal to (i) the greater of (A) the daily LIBOR Rate in effect from time to time or (B) 3.75%, plus (ii) the Applicable Margin in effect from time to time.

(b) Interest on each Loan shall be due and payable in cash in arrears on each Interest Payment Date and on the date of any prepayment (actual or due) of Loans pursuant to Sections 2.5 and 2.6.

(c) Upon the occurrence and during the continuance of any Event of Default, the Obligations shall bear interest at the Default Rate upon written notice of such increase given by the Agent to the Borrower; provided, that from and after the occurrence of any Event of Default under Sections VIII(a), (g) or (h), such increase shall be automatic and without notice from the Agent, Requisite Lenders or any other Person. In all such events, unless otherwise provided in the applicable notice by Agent to Borrower, and notwithstanding the date on which application of the Default Rate is communicated to Borrower, the Default Rate shall accrue from the initial date of such Event of Default until that Event of Default is waived in writing in accordance with the terms of this Agreement and shall be payable in cash upon demand. Neither Agent nor Lenders shall be required to (i) accelerate the maturity of the Loans, (ii) terminate any Commitment or (iii) exercise any other rights or remedies under the Loan Documents or applicable law in order to charge interest hereunder at the Default Rate.

2.4 Procedures for Advances under the Revolving Facility

Each Advance under the Revolving Facility shall be made upon Borrower’s irrevocable written notice to Agent requesting an Advance under the Revolving Facility in the form of a completed Borrowing Certificate, which Borrowing Certificate shall be delivered to Agent not later than 12:00p.m. (New York City time) at least one (1) but not more than four (4) Business

Days prior to the proposed Business Day on the Borrowing Date. Each such completed Borrowing Certificate requesting an Advance under the Revolving Facility shall:

(a) specify the proposed Borrowing Date of the requested Advance, which shall be a Business Day;

(b) specify the principal amount of the requested Advance (which shall be in an aggregate minimum principal amount of $50,000 and integral multiples of $25,000 in excess thereof); and

(c) certify the matters contained in Section 4.2.

On each Borrowing Date, Borrower irrevocably authorizes Agent and the Lenders to disburse the proceeds of the requested Advance to the Borrower’s account at:

Bank:	Royal Bank of Scotland

Account Name:	Evolving Systems Ltd

IBAN:	GB55 RBOS 1663 0000 3666 61

Swift:	RBOSGB2L

Branch:	151000

Account No:	00366661

or such other account to which Agent agrees (and which shall be subject to the Security Documents) (or to such other account, if approved by Agent, as to which Borrower shall instruct Agent in writing), for credit to Borrower via Federal funds wire transfer no later than 3:00p.m. (New York City time). Anything herein contained to the contrary notwithstanding, Agent and Lenders shall be entitled to rely upon the authority of any officer of Borrower for communications with and instructions from Borrower, including, without limitation, for purposes of this Section 2.4, until Agent has received written notice from Borrower that such officer no longer has such authority.

2.5 Mandatory Payments and Prepayments

(a) The principal amount of the Advances under the Revolving Facility, and all other Obligations under or in respect of the Revolving Facility shall be due and payable in full, if not earlier in accordance with this Agreement, on the Maturity Date.

(b) If it becomes unlawful in any applicable jurisdiction for a Lender to perform any of its obligations as contemplated by this Agreement or to fund, issue or maintain its participation in any Advance or other Obligation:

(i) that Lender shall promptly notify the Agent upon becoming aware of that event;

(ii) upon the Agent notifying the Borrower, the Commitment of that Lender will be cancelled on the earlier of immediately or on the date (if applicable) required by law; and

(iii) the Borrower shall repay that Lender’s participation in any Advances or Obligations to that Borrower promptly after the Agent has notified the Borrower or, if earlier, the date specified by the Lender in the notice delivered to the Agent (being no earlier than the last day of any applicable grace period permitted by law).

(c) If a Change of Control occurs that has not been consented to in writing by the Agent prior to consummation thereof, or any Credit Party or any Subsidiary of any Credit Party (other than to the extent any Credit Party is obliged to apply such proceeds in accordance with the terms of the Term Loan Agreement), whether in a single transaction or a series of transactions:

(i) sells or transfers any Property (other than any Qualified Asset Sale);

(ii) sells or issues any Capital Stock (excluding sales or issuances of Permitted Securities to the extent no Default or Event of Default has occurred and is continuing or would be caused thereby or result therefrom, but specifically including any sale or issuance of Capital Stock pursuant to a Public Offering);

(iii) receives any property damage insurance award or any other insurance proceeds of any kind, including, without limitation, proceeds from any life insurance (including the Life Insurance Policy) or business interruption insurance in excess of an amount equal to $100,000; or

(iv) incurs any Indebtedness other than Permitted Indebtedness,

then Borrower shall prepay the Loans and the other Obligations in an amount equal to one hundred percent (100%) of the Net Proceeds received by the Credit Parties and their Subsidiaries in connection therewith (or such lesser amount as is required to irrevocably pay in cash in full the Obligations), which prepayment shall be applied thereto in accordance with this Section 2.5(c); provided, that, the foregoing notwithstanding, if Borrower reasonably expects the Net Proceeds of any such sale or transfer in respect of the foregoing clause (i) or any such property damage insurance award under the foregoing clause (iii), or a portion thereof, to be reinvested in productive assets of a kind then used or usable in the Business, and, within one hundred eighty (180) days after such occurrence, enters into a binding commitment to make such reinvestment (which reinvestment shall be made within two hundred seventy (270) days after such occurrence), then Borrower shall deliver an amount equal to such Net Proceeds, or applicable portion thereof, to Agent to be, at Agent’s election, (x) applied to the Revolving Loans (without resulting in a permanent reduction in the Revolving Loan Commitment) or (y) held by Agent in a cash collateral account pending such reinvestment.

(d) All prepayments pursuant to this Section 2.5(b) and 2.5(c) shall be applied in the following order of priority: first, to all then unpaid fees and expenses of Agent under the Loan Documents, second, to all then unpaid fees and expenses of Lenders under the Loan Documents, third, to any and all Obligations that are due and owing pursuant to the terms of the Loan Documents, except the principal balance of the Loan and accrued and unpaid interest thereon; fourth, to all accrued and unpaid interest on the Revolving Loan; fifth, to the principal amount of Revolving Loans (with a corresponding permanent reduction in the Facility Cap).

(e) Any balance of Advances under the Revolving Facility outstanding at any time in excess of the lesser of (a) the Facility Cap in effect at such time less the Letter of Credit Usage then in effect and (b) the Aggregate Borrowing Availability in effect at such time (determined by reference to the Borrowing Base Certificate then most recently delivered to Agent in accordance with the terms hereof), shall be immediately due and payable by Borrower without the necessity of any notice or demand unless remedied within three (3) Business Days of the date of determination by the Borrower or notification by the Agent to the Borrower.

2.6 Promise to Pay; Manner of Payment

Borrower absolutely and unconditionally promises to pay, when due and payable pursuant hereto, principal, interest and all other amounts and Obligations payable hereunder and under any other Loan Document, without any right of rescission and without any deduction whatsoever, including any deduction for set-off, recoupment or counterclaim, notwithstanding any damage to, defects in or destruction of the Collateral or any other event, including obsolescence of any property or improvements. Any payments made by the Credit Parties (other than payments automatically paid through Advances under the Revolving Facility as provided herein) shall be made by wire transfer on the date when due, without offset, deduction or counterclaim in immediately available funds to such account as may be indicated in writing by Agent to Borrower from time to time. Any such payment received after 2:00p.m. (New York City time) on any date shall be deemed received on the next succeeding Business Day, and any applicable interest or fees shall continue to accrue in respect thereof. Whenever any payment under any Loan Document shall be stated to be due or shall become due and payable on a day other than a Business Day, the due date thereof shall be extended to, and such payment shall be made on, the next succeeding Business Day, and such extension of time in such case shall be included in the computation of payment of any interest (at the interest rate in effect during such extension) and/or fees, as the case may be. All payments of principal, interest, fees, expenses and all other amounts hereunder shall be payable in Dollars.

2.7 Payments by Agent

Should any Obligation required to be paid under any Loan Document remain unpaid beyond any applicable cure period, such Obligation may be paid by Agent, on behalf of Lenders, which non-payment shall be deemed an automatic request for an Advance under the Revolving Facility as of the date such payment is or was due, and Borrower hereby irrevocably authorizes disbursement of any such funds to Agent, for the benefit of Lenders, by way of direct payment of the relevant amount, interest or other Obligation without necessity of any demand. Any sums expended or amounts paid by Agent and/or Lenders as a result of any Credit Party’s failure to

pay, perform or comply with any Loan Document or any of the Obligations may be charged to Borrower’s account as an Advance under the Revolving Facility and added to the Obligations.

2.8 Computation of Interest and Fees; Lawful Limits

All interest and fees owing from time to time under the Loan Documents shall be computed on the basis of a year of 360 days and for the actual number of days elapsed in each calculation period, as applicable. In no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the interest and other charges paid or agreed to be paid to Agent, for the benefit of Lenders, or Lenders for the use, forbearance or detention of money hereunder exceed the maximum rate permissible under applicable law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. If, due to any circumstance whatsoever, fulfilment of any provision hereof, at the time performance of such provision shall be due, shall exceed any such limit, then, the obligation to be so fulfilled shall be reduced to such lawful limit, and, if Agent or Lenders shall have received interest or any other charges of any kind which might be deemed to be interest under applicable law in excess of the maximum lawful rate, then such excess shall be applied first to any unpaid fees and charges hereunder, then to the unpaid principal balance owed by Borrower hereunder, and if the then remaining excess interest is greater than the previously unpaid principal balance, Agent and Lenders shall promptly refund such excess amount to Borrower and the provisions hereof shall be deemed amended to provide for such permissible rate. The terms and provisions of this Section 2.8 shall control to the extent any other provision of any Loan Document is inconsistent herewith.

2.9 Collections

In accordance with the Debenture, the Borrower and the UK Guarantor shall cause all cash payments received by them for their benefit to be promptly deposited into a Security Account for which a first priority perfected Lien has been created thereon in favour of the Lender Parties.

2.10 Reallocation of Commitments

The Credit Parties, Agent and the Lenders agree and acknowledge that, on terms and conditions satisfactory to the Borrower, each Term Borrower, Agent, each of the Lenders, and the Term Lender, any Commitment of any Lender hereunder and the Term Lender under the Term Loan Agreement for the benefit of the Borrower or Term Borrower may be reallocated and adjusted from time to time with any other Commitment or Commitments of such Lender under this Agreement or Lender for the benefit of the other Borrower or Term Borrowers, and the outstanding Loans thereunder and hereunder reclassified or re-categorized in connection therewith and herewith to evidence or effectuate any such reallocation and adjustment, without constituting a novation, for any purpose, including, without limitation, for purposes of accurately reflecting each Borrower’s or Term Borrower’s relative contribution to, or allocable amount or share of, Evolving System’s Consolidated EBITDA, earnings, revenue, assets and/or liabilities. For clarification purposes, any such reallocation and adjustment shall require the written consent of the Borrower, each Term Borrower, Agent, each Lender and Term Lender and shall not, in any event, result in (a) a reduction of the aggregate Commitments contained herein and in the Term Loan Agreement or (b) any breach of Sections 151 to 158 of the Act.

2.11 Market disruption

(a) If a Market Disruption Event occurs in relation to a Loan, then the rate of interest on each Lender’s share of that Loan shall be the rate per annum which is the sum of:

(i) the Applicable Margin;

(ii) the greater of (A) rate notified to the Agent by that Lender as soon as practicable and in any event before interest is due to be paid in respect of that Loan, to be that which expresses as a percentage rate per annum the cost to that Lender of funding its participation in that Loan from whatever source it may reasonably select or (B) 3.75%; and

(iii) any Eurocurrency Reserve Requirement of the Lenders if applicable.

(b) In this Agreement “Market Disruption Event” means:

(i) at or about noon on the Borrowing Date the Screen Rate is not available to determine the LIBOR Rate; or

(ii) before close of business in London on the Borrowing Date, the Agent receives notifications from a Lender or Lenders (whose participations in a Loan exceed 25 per cent of that Loan) that the cost to it of obtaining matching deposits in the Relevant Interbank Market would be in excess of LIBOR.

(c) Alternative basis of interest or funding

(i) If a Market Disruption Event occurs and the Agent or the Borrower so requires, the Agent and the Borrower shall enter into negotiations (for a period of not more than 30 days) with a view to agreeing a substitute basis for determining the rate of interest.

(ii) Any alternative basis agreed pursuant to clause 2.11(c) shall, with the prior consent of all the Lenders and the Borrower, be binding on all Parties.

2.12 Increased Costs

(a)

(i) Subject to clause 2.11(c) and 2.12(d) the Borrower shall, within three Business Days of a demand by the Agent, pay for the account of a Lender the amount of any Increased Costs incurred by that Lender as a result of (i) the introduction of or any change in (or in the interpretation, administration or application of) any law or regulation or (ii) compliance with any law or regulation made after the date of this Agreement.

(ii) In this Agreement “Increased Costs” means:

(1) a reduction in the rate of return from the Revolving Facility or on a Lender Party’s (or its Affiliate’s) overall capital;

(2) an additional or increased cost; or

(3) a reduction of any amount due and payable under any Loan Document,

which is incurred or suffered by a Lender to the extent that it is attributable to that Lender having entered into its Commitment or funding or performing its obligations under the Loan Document or Letter of Credit provided, however that any amounts that such Lender is already receiving by adjusting the Eurocurrency Reserve Requirements pursuant to the definition of Libor Rate shall not be included in the Increased Costs.

(b)

(i) A Lender intending to make a claim pursuant to clause 2.12(a) shall notify the Agent of the event giving rise to the claim, following which the Agent shall promptly notify the Borrower.

(ii) Each Lender shall, as soon as practicable after a demand by the Agent, provide a certificate confirming the amount of its Increased Costs.

(c)

(i) Clause 2.12(a) does not apply to the extent any Increased Cost is:

(1) attributable to a Tax deduction required by law to be made by a Credit Party;

(2) compensated for by clause 13.1 but was not so compensated solely because any of the exclusions in clause 13.1 applied or is attributable to Taxes for which no compensation is required in clause 13.1; and

(3) attributable to the wilful breach by the relevant Lender Party or its Affiliates of any law or regulation.

(d) Each Lender agrees to designate a different lending office if such designation will avoid the need for, or reduce the amount of, any compensation pursuant to this Section and will not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

2.13 Letter of Credit.

Subject to the terms and conditions set forth in this Agreement and on Appendix B hereto, Borrower shall have the right to request, and the Lenders agree to incur, or purchase participations in, Letters of Credit in respect of Borrower and the other Credit Parties so long as

none of the Letters of Credit are used directly or indirectly to benefit the Subordinated Note Holders or otherwise violate Sections 151 to 158 of the Act.

III. FEES

3.1 Commitment Fee

On the Closing Date, Borrower shall pay to Agent, for the rateable benefit of Lenders, a nonrefundable commitment fee equal to Sixty Seven Thousand Five Hundred Dollars ($67,500.00), which commitment fee shall be deemed fully earned and due and payable on the Closing Date and in addition to any other fee from time to time payable under the Loan Documents.

3.2 Management Fee

Borrower shall pay to Agent a management fee (the “Management Fee”) in an amount equal to one-half of one percent (0.5%) per annum of the daily average of the aggregate of (i) the Facility Cap for each day of each month and (ii) any additional amounts advanced under the Revolving Facility in excess of the Facility Cap for each day outstanding. The Management Fee shall be payable monthly in arrears on the first day of each calendar month, commencing with the month immediately succeeding the month in which the Closing Date occurs, provided that the amount payable for the first and last month shall be proportional to the number of days in such month in which the Commitment is outstanding.

3.3 Letter of Credit Fees

Borrower shall pay to Agent, for the rateable benefit of Lenders, a Letter of Credit fee equal to (i) two or three quarters percent (2.75%) per annum of the aggregate undrawn face amount of all outstanding Standby Letters of Credit issued for the account of Borrower (the “Standby Letter of Credit Fee”), which fee shall be payable in arrears on each Interest Payment Date and (ii) one quarter of one percent (.25%) of the aggregate undrawn face amount of any such Documentary Letter of Credit issued for the account of Borrower and payable upon issuance (together with the Standby Letter of Credit Fees plus normal and customary issuance, presentation, amendment, processing and other administrative costs and expenses incurred by L/C Issuer, the “Letter of Credit Fees”). Upon the occurrence and during the continuance of any Event of Default, all Letter of Credit Fees shall be payable on demand at a rate equal to the Letter of Credit Fee, plus four percent (4.00%) per annum, in each case on the aggregate undrawn face amount of all outstanding Letters of Credit issued for the account of Borrower. Borrower shall also pay on demand the normal and customary administrative charges for issuance, amendment, negotiation, renewal or extension of any Standby Letter of Credit or Documentary Letter of Credit imposed by the L/C Issuer.

On demand by Agent at any time after the occurrence and during the continuance of any Event of Default, Borrower will cause cash to be deposited and maintained in an account with Agent, as cash collateral, in an amount equal to one hundred and five percent (105%) of the Letter of Credit Usage, and Borrower hereby irrevocably authorizes Agent, in its discretion, on Borrower’s behalf and in Borrower’s name, to open such an account and to make and maintain

deposits therein, or in an account opened by Borrower, in the amounts required to be made by Borrower, out of the proceeds of Accounts or other Collateral or out of any other funds of any Credit Party coming into any Lender’s possession at any time. Agent will invest such cash collateral (less applicable reserves) in such short-term money-market items as to which Agent in its Permitted Discretion may determine and the net return on such investments shall be credited to such account and constitute additional cash collateral. Borrower may not withdraw amounts credited to any such account except upon the earlier of (i) payment and performance in full of all Obligations (other than contingent indemnification obligations under the Loan Documents for which no claim giving rise thereto has been asserted) and termination of this Agreement and (ii) at such time as such Event of Default no longer exists unless Agent determines in its Permitted Discretion not to release such amounts but in any event, Agent shall apply any amounts in such account to the repayment of any Letter of Credit disbursements.

Upon request of Agent or any Lender, Evolving Systems shall furnish to Agent, with sufficient copies for each Lender, at reasonable intervals (but not more than once per calendar year) a certificate of a Responsible Officer on behalf of Evolving Systems (and, if requested by Agent, any insurance broker of Evolving Systems) setting forth the nature and extent of all insurance maintained by Evolving Systems and its Subsidiaries in accordance with this Section 6.4.

IX. RIGHTS AND REMEDIES AFTER DEFAULT

9.1 Rights and Remedies

(a) In addition to the acceleration and other provisions set forth in Article VIII, upon the occurrence and during the continuation of an Event of Default, Agent shall have the right to (and at the request of Requisite Lenders, shall) exercise any and all rights and remedies provided for in any Loan Document or any Term Loan Document, at law or in equity, including, without limitation, the right to the extent permitted by applicable law, to (i) apply any Property of any Credit Party held by Agent, for the benefit of the Lender Parties, or any Lender to reduce the Obligations, (ii) foreclose the Liens created under the Loan Documents or the Term Loan Documents, (iii) enforce, realize upon, take possession of and/or sell or otherwise transfer any Collateral or securities pledged, with or without judicial process, (iv) exercise all rights and powers with respect to the Collateral as any Credit Party might exercise, (v) collect and send notices regarding the Collateral, with or without judicial process, (vi) by its own means or with judicial assistance, enter any premises at which Collateral and/or pledged securities are located, or render any of the foregoing unusable or dispose of the Collateral and/or pledged securities on such premises without any liability for rent, storage, utilities, or other sums, and no Credit Party shall resist or interfere with such action, (vii) at Credit Parties’ expense, require that all or any part of the Collateral be assembled and made available to Agent at any place where the Credit Parties regularly maintain inventory or Property designated by Agent in its Permitted Discretion, (viii) reduce or otherwise change the Facility Cap, Availability, Aggregate Borrowing Availability and/or any component of the foregoing and/or (ix) relinquish or abandon any Collateral or securities pledged or any Lien thereon. Notwithstanding any provision of any Loan Document, Agent, in its Permitted Discretion, shall have the right, at any time that any Credit Party fails to do so, and from time to time, without prior notice, to: (i) obtain insurance covering any of the Collateral to the extent required hereunder; (ii) pay for the performance of any of the Obligations; (iii) discharge taxes, levies and/or Liens on any of the Collateral that are in violation of any Loan Document; and (iv) pay for the maintenance, repair and/or preservation of the Collateral. Such expenses and advances shall be added to the Obligations until reimbursed to Agent and shall be secured by the Collateral and payable on demand, and such payments by Agent shall not be construed as a waiver by Agent or Lenders of any Event of Default or any other rights or remedies of Agent and Lenders. Notwithstanding anything to the contrary in this Agreement, neither the Agent nor any Lender shall have any right or authority to take possession of and/or sell or otherwise transfer any Collateral pledged by the Borrower and UK Guarantor under the Revolving Loan Documents for the benefit of any Lender under the Term Loan Documents or the payment of any amounts under the Subordinated Notes, or in repayment or

satisfaction of any amount owing by any of the Credit Parties under and as defined in the Term Loan Documents.

(b) The Credit Parties jointly and severally agree that notice received by any of them at least ten (10) calendar days before the time of any intended public sale, or the time after which any private sale or other disposition of Collateral is to be made, shall be deemed to be reasonable notice of such sale or other disposition. If permitted by applicable law, any perishable Collateral which threatens to speedily decline in value or which is sold on a recognized market may be sold immediately by Agent without prior notice to any Credit Party. At any sale or disposition of Collateral or securities pledged, Agent may (to the extent permitted by applicable law) purchase all or any part thereof free from any right of redemption by the Credit Parties, which right hereby is waived and released. The Credit Parties jointly and severally covenant and agree not to, and not to permit or cause any of their Subsidiaries to, interfere with or impose any obstacle to Agent’s exercise of its rights and remedies with respect to the Collateral. In dealing with or disposing of the Collateral or any part thereof, Agent and Lenders shall not be required to give priority or preference to any item of Collateral or otherwise to marshal assets or to take possession or sell any Collateral with judicial process.

(c) Each Credit Party hereby grants to Agent, for the benefit of the Lender Parties, after the occurrence and during the continuance of an Event of Default, an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to such Credit Party) to use, assign, license or sublicense any Intellectual Property, (unless such use, assignment, license or sublicense is expressly prohibited under a license agreement and would result in a breach under such agreement for which such agreement would reasonably be expected to be terminated by such licensor) and now owned or hereafter acquired by such Credit Party, and wherever the same may be located, including in such license reasonable access as to all media in which any of the licensed items may be recorded or stored and to all computer programs and used for the compilation or printout thereof. All proceeds received by Agent or Lenders in connection with such license shall be used by Agent or Lenders to satisfy the Obligations.

(d) In addition to the acceleration and other provisions set forth in Article VIII, upon the occurrence and during the continuation of an Event of Default, each Credit Party shall take any action that Agent, for the benefit of itself and the Lenders, may request in order to enable Agent to obtain and enjoy the full rights and benefits granted to Agent hereunder.

9.2 Application of Proceeds

In addition to any other rights and remedies Agent and Lenders have under the Loan Documents or the Term Loan Documents, the UCC, at law or in equity, all payments received after the occurrence and during the continuation of any Event of Default, and all proceeds collected or received from collecting, holding, managing, renting, selling or otherwise disposing of all or any part of the Collateral or any proceeds thereof upon exercise of remedies hereunder upon the occurrence and during the continuation of an Event of Default, shall be applied in the following order of priority:

(i) first, to the payment of all costs and expenses of such collection, holding, managing, renting, selling or disposition, and of conducting the Credit Parties’ Businesses and of maintenance, repairs, replacements, alterations, additions and improvements of or to the Collateral, and to the payment of all sums which Agent or Lenders may be required or may elect to pay, if any, for taxes, assessments, insurance and other charges upon the Collateral or any part thereof, and all other payments that Agent or Lenders may be required or authorized to make under any provision of the Loan Documents (including, without limitation, in each such case, in-house documentation and diligence fees and legal expenses, search, audit, recording, professional and filing fees and expenses and reasonable attorneys’ fees and all expenses, liabilities and advances made or incurred in connection therewith);

(ii) second, to payment of all accrued unpaid interest on the Obligations and fees owed to the Agent and Lenders;

(iii) third, to payment of principal of the Obligations;

(iv) fourth, to payment of any other amounts owing constituting Obligations; and

(v) fifth, any surplus then remaining to the Credit Parties, unless otherwise provided by law or directed by a court of competent jurisdiction;

provided that the Credit Parties shall be liable for any deficiency if such proceeds are insufficient to satisfy all of the Obligations or any of the other items referred to in this Section. In carrying out the foregoing, (x) amounts received shall be applied in the numerical order provided until exhausted prior to the application to the next succeeding category; and (y) each of the Lenders shall receive an amount equal to its pro rata share of amounts available to be applied pursuant to clauses (i), (ii), (iii) and (iv) above.

9.3 Rights to Appoint Receiver

Without limiting any other rights, options and remedies Agent and Lenders have under the Loan Documents or the Term Loan Documents, the UCC, at law or in equity, upon the occurrence and during the continuation of an Event of Default, Agent shall have the right to apply for and have a receiver appointed by a court of competent jurisdiction in any action taken by Agent to enforce its and Lenders’ rights and remedies in order to manage, protect and preserve the Collateral, to sell or dispose of the Collateral and continue the operation of the Businesses of the Credit Parties and to collect all revenues and profits thereof and apply the same to the payment of all expenses and other charges of such receivership including the compensation of the receiver and to the payments as aforesaid until a sale or other disposition of such Collateral shall be finally made and consummated. To the extent not prohibited by applicable law, each Credit Party hereby irrevocably consents to, and waives any right to object to or otherwise contest, the appointment of, a receiver as provided above.

9.4 Rights and Remedies not Exclusive

As among the Lender Parties on one hand and the Credit Parties on the other hand, Agent and Lenders shall have the right in their sole discretion to determine which rights, Liens and/or remedies Agent and/or Lenders may at any time pursue, relinquish, subordinate or modify, and such determination shall not in any way modify or affect any of Agent’s or Lenders’ rights, Liens or remedies under any Loan Document, Term Loan Documents applicable law or equity. The enumeration of any rights and remedies in any Loan Document, or any Term Loan Document, is not intended to be exhaustive, and all rights and remedies of Agent and the Lenders described in any Loan Document and the Term Loan Documents are cumulative and are not alternative to or exclusive of any other rights or remedies which Agent and Lenders otherwise may have, subject to the limitation contained in the last sentence of Section 9.1(a). The partial or complete exercise of any right or remedy shall not preclude any other further exercise of such or any other right or remedy.

X. WAIVERS

10.1 Certain Waivers

Except as expressly provided for herein or in any other Loan Document, each Credit Party hereby waives set-off, counterclaim, demand, presentment, protest, all defenses with respect to any and all instruments and all notices and demands of any description, and the pleading of any statute of limitations as a defense to any demand under any Loan Document. Each Credit Party hereby waives any and all defenses and counterclaims it may have or could interpose in any action or procedure brought by Agent or any Lender to obtain an order of court recognizing the assignment of, or Lien of Agent, for the benefit the Lender Parties, in and to, any Collateral.

10.2 Delay; No Waiver of Defaults

No course of action or dealing, renewal, release or extension of any provision of any Loan Document, or single or partial exercise of any such provision, or delay, failure or omission on Agent’s or any Lender’s part in enforcing any such provision shall affect the liability of any Credit Party or operate as a waiver of such provision or affect the liability of any Credit Party or preclude any other or further exercise of such provision. No waiver by any party to any Loan Document of any one or more defaults by any other party in the performance of any of the provisions of any Loan Document shall operate or be construed as a waiver of any future default, whether of a like or different nature, and each such waiver shall be limited solely to the express terms and provisions of such waiver. Notwithstanding any other provision of any Loan Document or any Term Loan Document, by completing the Closing under this Agreement and/or by making Advances, neither Agent nor any Lender waives any breach of any representation or warranty of any Credit Party under any Loan Document or any Term Loan Documents, and all of Agent’s and Lenders’ claims and rights resulting from any such breach or misrepresentation hereby specifically are reserved.

10.3 Amendment and Waivers

Except as otherwise provided herein, no amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, or consent to any departure by the Credit Parties or any of them therefrom, shall be effective unless the same shall be in writing and signed by Requisite Lenders (or Agent at the direction of the Requisite Lenders) and each Credit Party; provided, that no amendment, modification, termination or waiver shall, unless in writing and signed by each Credit Party and each Lender directly affected thereby, do any of the following: (i) increase the Commitment of any individual Lender (which action shall be deemed to directly affect all Lenders); (ii) reduce the principal of, rate of interest on or fees payable with respect to any Loan or other Obligation; (iii) extend the scheduled due date, or reduce the amount due on any scheduled due date, of any installment of principal, interest or fees payable under any Loan Document, or waive, forgive, extend, defer or postpone the payment thereof; (iv) change the percentage of the Commitments, of the aggregate unpaid principal amount of the Loans, or of Lenders which shall be required for Lenders, Agent or any of them to take any action hereunder (which action shall be deemed to directly affect all Lenders) or alter, as between or among the Lenders, the amount payable to each hereunder; (v) except as otherwise permitted herein or in the other Loan Documents, release any Guaranty or release any material portion of the Collateral (which action shall be deemed to directly affect all Lenders) (provided, that consent to such release shall not be required if such release is made after the occurrence and during the continuation of an Event of Default in connection with the sale or disposition of the Collateral by Agent otherwise permitted hereunder); (vi) amend, modify or waive this Section 10.3 or the definitions of the terms used in this Section 10.3 insofar as the definitions affect the substance of this Section 10.3 (which action shall be deemed to directly affect all Lenders); and/or (vii) consent to the assignment or other transfer by any Credit Party or any other party to any Loan Documents (other than Agent or any Lender) of any of their rights and obligations under any Loan Document; and provided, further, that no amendment, modification, termination or waiver affecting the rights or duties of Agent under any Loan Document shall be effective unless in writing and signed by Agent, in addition to Lenders required hereinabove to take such action. Notwithstanding anything contained in this Agreement to the contrary, no waiver or consent with respect to any Default (if in connection therewith Lenders have exercised their right to suspend the making or incurrence of Advances) or any Event of Default shall be effective for purposes of the conditions precedent to the making of Advances unless the same shall be in writing and signed by Lenders holding at least a majority of the Commitments in respect of the Revolving Facility. Any amendment, modification, termination, waiver or consent effected in accordance with this Section 10.3 shall be binding upon Agent, each Lender and the Credit Parties.

(b) All Loans and other Obligations shall be due and payable in full in cash, if not earlier in accordance with this Agreement, on the Maturity Date. All of Agent’s and Lenders’ rights and remedies and the Liens in the Collateral shall continue in full force and effect until, and this Agreement shall terminate when all Obligations have been fully performed and indefeasibly paid in full in cash and Credit Parties shall have executed and delivered releases in favor of Agent and Lenders in form and substance satisfactory to Agent, in its Permitted Discretion (provided, however, that the release may exclude claims filed by a Credit Party against Agent or a Lender prior to the payoff contemplated in this Section 10.4(b), arising out of the gross negligence, wilful misconduct or fraud of Agent or such Lender). Accordingly, each Credit Party waives any right it may have under the UCC (to the extent the UCC applies) to demand the filing of termination statements with respect to the Collateral other than such right in connection with the release of Liens pursuant to sales or other dispositions of assets expressly permitted under the terms of this Agreement, and Agent shall not be required to provide such termination statements or to file them with any filing office unless and until all conditions to the termination of this Agreement and the payment and performance of the Obligations are satisfied in a manner acceptable to Agent, in its Permitted Discretion.

XI. AGENT PROVISIONS; SETTLEMENT

11.1 Agent

(a) Appointment. In addition to any appointments in the Term Loan Documents, each Lender hereby designates and appoints CapitalSource (i) as the administrative agent, payment agent and collateral agent under this Agreement and the other Loan Documents and (ii) to hold all of the rights and interests created by the Security Documents on trust and as agent for the Lenders in respect of the Obligations and each Lender hereby irrevocably authorizes CapitalSource, as Agent for such Lender, to take such action or to refrain from taking such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are delegated to Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Agent agrees to act as such on the conditions contained in this Article XI. The provisions of this Article XI are solely for the benefit of Agent and Lenders, and the Credit Parties shall have no rights as third-party beneficiaries of any of the provisions of this Article XI other than Section 11.1(h)(iii)Agent may perform any of its duties hereunder, or under the Loan Documents, by or through its agents, employees or sub-agents.

(b) Nature of Duties. In performing its functions and duties under this Agreement, Agent is acting solely on behalf of Lenders, and its duties are administrative in nature, and does not assume and shall not be deemed to have assumed, any obligation toward or relationship of agency or trust with or for Lenders, other than as expressly set forth herein and in the other Loan Documents, or the Credit Parties. Agent shall have no duties, obligations or responsibilities except those expressly set forth in this Agreement or in the other Loan Documents. Agent shall not have by reason of this Agreement or any other Loan Document a

fiduciary relationship in respect of any Lender. Each Lender shall make its own independent investigation of the financial condition and affairs of the Credit Parties in connection with the extension of credit hereunder and shall make its own appraisal of the creditworthiness of the Credit Parties. Except for information, notices, reports and other documents expressly required to be furnished to Lenders by Agent hereunder or given to Agent for the account of or with copies for Lenders, Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before the Closing Date or at any time or times thereafter. If Agent seeks the consent or approval of any Lenders to the taking or refraining from taking any action hereunder, then Agent shall send prior written notice thereof to each Lender. Agent shall promptly notify each Lender in writing any time that the applicable percentage of Lenders have instructed Agent to act or refrain from acting pursuant hereto.

(c) Rights, Exculpation, Etc. Neither Agent nor any of its officers, directors, managers, members, equity owners, employees, attorneys or agents shall be liable to any Lender for any action lawfully taken or omitted by them hereunder or under any of the other Loan Documents, or in connection herewith or therewith; provided that the foregoing shall not prevent Agent from being be liable to the extent of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction on a final and nonappealable basis. Notwithstanding the foregoing, Agent shall be obligated on the terms set forth herein for performance of its express duties and obligations hereunder. Agent shall not be liable for any apportionment or distribution of payments made by it in good faith, and if any such apportionment or distribution is subsequently determined to have been made in error, the sole recourse of any Lender to whom payment was due but not made shall be to recover from the other Lenders any payment in excess of the amount to which they are determined to be entitled (and such other Lenders hereby agree promptly to return to such Lender any such erroneous payments received by them). In performing its functions and duties hereunder, Agent shall exercise the same care which it would in dealing with loans for its own account. Agent shall not be responsible to any Lender for any recitals, statements, representations or warranties made by the Credit Parties herein or for the execution, effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Agreement or any of the other Loan Documents or the transactions contemplated thereby, or for the financial condition of the Credit Parties. Agent shall not be required to make any inquiry concerning either the performance or observance of any of the terms, provisions, or conditions of this Agreement or any of the Loan Documents or the financial condition of the Credit Parties, or the existence or possible existence of any Default or Event of Default. Agent may at any time request instructions from Lenders with respect to any actions or approvals which by the terms of this Agreement or of any of the other Loan Documents Agent is permitted or required to take or to grant, and Agent shall be absolutely entitled to refrain from taking any action or to withhold any approval and shall not be under any liability whatsoever to any Person for refraining from taking any action or withholding any approval under any of the Loan Documents until it shall have received such instructions from the applicable percentage of Lenders. Without limiting the foregoing, no Lender shall have any right of action whatsoever against Agent as a result of Agent acting or refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of the applicable percentage of Lenders and, notwithstanding the instructions of Lenders, Agent shall have no obligation to take any action if it, in good faith, believes that such action exposes Agent or any of its officers, directors, managers, members, equity owners, employees, attorneys or

agents to any personal liability unless Agent receives an indemnification satisfactory to it from Lenders with respect to such action.

(d) Reliance. Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any telephone message or other communication (including any writing, telex, telecopy or telegram) believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement, any of the other Loan Documents or the Term Loan Documents and its duties hereunder or thereunder, upon advice of legal counsel, independent accountants and other experts selected by Agent in its sole discretion.

(e) Indemnification. Each Lender, severally and not (i) jointly or (ii) jointly and severally, agrees to reimburse and indemnify and hold harmless Agent and its officers, directors, managers, members, equity owners, employees, attorneys and agents (to the extent not reimbursed by the Credit Parties), ratably according to their respective Pro Rata Share in effect on the date on which indemnification is sought under this subsection of the total outstanding Obligations (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with their Pro Rata Share immediately prior to such date of the total outstanding Obligations), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances, or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against Agent or any of its officers, directors, managers, members, equity owners, employees, attorneys or agents in any way relating to or arising out of this Agreement, any of the other Loan Documents or any of the Term Loan Documents or any action taken or omitted by Agent under this Agreement, any of the other Loan Documents or any of the Term Loan Documents; provided, however, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances or disbursements to the extent resulting from Agent’s gross negligence or wilful misconduct as determined by a court of competent jurisdiction on a final and nonappealable basis. The obligations of Lenders under this Article XI shall survive the payment in full of the Obligations and the termination of this Agreement.

(f) CapitalSource Individually. With respect to the Loans made by it or CSE Finance and the Notes, if any, issued to it or CSE Finance, CapitalSource and CSE Finance shall have, and may exercise, the same rights and powers hereunder and under the other Loan Documents, and is subject to the same obligations and liabilities, as and to the extent set forth herein and the other Loan Documents as any other Lender. The terms “Lenders” or “Requisite Lenders” or any similar terms shall, unless the context clearly otherwise indicates, include CSE Finance in its individual capacity as a Lender or one of the Requisite Lenders. CapitalSource (and its Affiliates) may lend money to, and generally engage in any kind of banking, trust or other business with, any Credit Party or any Subsidiary or Affiliate of any Credit Party as if it were not acting as Agent pursuant hereto.

(g) Successor Agent.

(i) Resignation. Agent may resign from the performance of all or part of its functions and duties hereunder at any time by giving at least thirty (30)

calendar days’ prior written notice to Borrower and Lenders. Such resignation shall take effect upon the acceptance by a successor Agent of appointment pursuant to clause (ii) below or as otherwise provided below.

(ii) Appointment of Successor. Upon any such notice of resignation pursuant to clause (g)(i) of this Section 11.1, Requisite Lenders shall appoint a successor Agent with the consent of Borrower, which consent shall not be unreasonably withheld, delayed or conditioned (or required if any Default or Event of Default exists). If a successor Agent shall not have been so appointed within said thirty (30) calendar day period referenced in clause (g)(i) above, the retiring Agent, upon notice to Borrower, may, on behalf of Lenders, appoint a successor Agent with the consent of Borrower, which consent shall not be unreasonably withheld, delayed or conditioned (or required if any Default or Event of Default exists), who shall serve as Agent until such time as Requisite Lenders appoint a successor Agent as provided above. If no successor Agent has been appointed pursuant to the foregoing within said thirty (30) calendar day period, the resignation shall become effective and Requisite Lenders thereafter shall perform all the duties of Agent hereunder, until such time, if any, as Requisite Lenders appoint a successor Agent as provided above.

(iii) Successor Agent. Upon the acceptance of any appointment as Agent under the Loan Documents by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent and, upon the earlier of such acceptance or the effective date of the retiring Agent’s resignation, the retiring Agent shall be discharged from its duties and obligations under the Loan Documents, provided that any indemnity rights or other rights in favor of such retiring Agent shall continue after and survive such resignation and succession. After any retiring Agent’s resignation as Agent under the Loan Documents, the provisions of this Article XI shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents.

(h) Collateral Matters.

(i) Collateral. Each Lender agrees that any action taken by Agent or the Requisite Lenders (or, where required by the express terms of this Agreement, a greater proportion of Lenders) in accordance with the provisions of this Agreement or of the other Loan Documents relating to the Collateral, and the exercise by Agent or the Requisite Lenders (or, where so required, such greater proportion of Lenders) of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders and Agent. Without limiting the generality of the foregoing, Agent shall have the sole and exclusive right and authority to (i) act as the disbursing and collecting agent for Lenders with respect to all payments and collections arising in connection herewith and with the Loan Documents in connection with the Collateral; (ii) execute and deliver each Loan Document relating to the Collateral and any Subordination Agreement and accept delivery of each such agreement delivered by the Credit Parties or any of their Subsidiaries; (iii) act as collateral agent for Lenders for purposes of the perfection of all security interests and Liens created by such agreements and all other purposes stated

therein; (iv) manage, supervise and otherwise deal with the Collateral; (v) take such action as is necessary or desirable to maintain the perfection and priority of the security interests and Liens created or purported to be created by the Loan Documents relating to the Collateral; and (vi) except as may be otherwise specifically restricted by the terms hereof or of any other Loan Document, exercise all remedies given to such Agent and Lenders with respect to the Collateral under the Loan Documents relating thereto, applicable law or otherwise.

(ii) Release of Collateral. Lenders hereby irrevocably authorize Agent, at its option and in its sole discretion, to release any Lien granted to or held by Agent for the benefit of Lender Parties upon any Property covered by the Loan Documents (A) upon termination of this Agreement and payment and satisfaction in full of all Obligations; (other than contingent indemnification Obligations to the extent no claim giving rise thereto has been asserted), (B) constituting Property being sold or disposed of if Borrower certifies to Agent that the sale or disposition is made in compliance with the provisions of the Loan Documents (and Agent may rely in good faith conclusively on any certificate of the Borrower to such effect, without further inquiry); or (C) constituting Property leased to any Credit Party under a lease which has expired or been terminated in a transaction permitted under this Agreement or is about to expire and which has not been, and is not intended by such Credit Party to be, renewed or extended.

(iii) Confirmation of Authority; Execution of Releases. Without in any manner limiting Agent’s authority to act without any specific or further authorization or consent by Lenders (as set forth in Section 11.1(h)(i) and (ii)), each Lender agrees to confirm in writing, upon request by Borrower, the authority to release any property covered by this Agreement or the Loan Documents conferred upon Agent under Section 11.1(h)(ii). So long as no Event of Default exists, upon receipt by Agent of confirmation from the requisite percentage of Lenders of its authority to release any particular item or types of Property covered, by this Agreement or the other Loan Documents, and upon at least five (5) Business Days’ prior written request by Borrower, Agent shall (and is hereby irrevocably authorized by Lenders to) execute such documents as may be necessary to evidence the release of the Liens granted to Agent for the benefit of the Lender Parties herein or pursuant hereto upon such Collateral; provided, however, that (A) Agent shall not be required to execute any such document on terms which, in Agent’s opinion, would expose Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty (other than that such Collateral is free and clear, on the date of such delivery, of any and all Liens arising under the Loan Documents or from such Person’s own acts), and (B) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or obligations of the Credit Parties or any Subsidiary of any Credit Party in respect of) all interests retained by the Credit Parties or any Subsidiary of a Credit Party including, without limitation, the proceeds of any sale, all of which shall continue to constitute part of the Property covered by this Agreement, the Loan Documents or subject to the last sentence of Section 9.1(a),the Term Loan Documents.

(iv) Absence of Duty. Agent shall have no obligation whatsoever to any Lender or any other Person to assure that the Property covered by this Agreement or the other Loan Documents exists or is owned by any Credit Party or is cared for, protected or insured or has been encumbered or that the Liens granted to Agent on behalf of the Lender Parties herein or pursuant hereto have been properly or sufficiently or lawfully created, perfected, protected, enforced or maintained or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to Agent in this Section 11.1(h) or in any of the other Loan Documents, it being understood and agreed that in respect of the Property covered by this Agreement or the other Loan Documents or any act, omission, or event related thereto, Agent may act in any manner it may deem appropriate, in its discretion, given Agent’s own interest in Property covered by this Agreement or the other Loan Documents as one of Lenders and Agent shall have no duty or liability whatsoever to any of the other Lenders; provided, that Agent shall exercise the same care which it would in dealing with loans for its own account. Notwithstanding the foregoing, Agent shall be liable with respect to its own gross negligence or wilful misconduct.

(i) Agency for Perfection. Each Lender hereby appoints Agent as agent for the purpose of perfecting Lenders’ security interest in Collateral which in any applicable jurisdiction, can be perfected only by possession or control. Should any Lender (other than Agent) obtain possession of any such Collateral, such Lender shall hold such Collateral for purposes of perfecting a security interest therein for the benefit of the Lender Parties, notify Agent thereof and, promptly upon Agent’s request therefor, deliver such Collateral to Agent or otherwise act in respect thereof in accordance with Agent’s instructions.

(j) Exercise of Remedies. Except as set forth in Section 11.2, each Lender agrees that it will not have any right individually to enforce or seek to enforce this Agreement or any other Loan Document or to realize upon any Collateral security for the Loans or other Obligations; it being understood and agreed that such rights and remedies may be exercised only by Agent in accordance with the terms of the Loan Documents.

(k) Consents.

(i) In the event Agent requests the waiver or consent of a Lender and does not receive a written denial thereof within five (5) Business Days after such Lender’s receipt of such request, then such Lender will be deemed to have given such waiver of consent so long as such request contained a notice stating that such failure to respond within five (5) Business Days would be deemed to be a waiver or consent by such Lender.

(ii) In the event Agent requests the waiver or consent of a Lender in a situation where such Lender’s waiver or consent would be required and such waiver or consent is denied, then Agent or any of its Eligible Assignees may, at its option, require such Lender to assign its interest in the Loans to Agent for a price equal to the then outstanding principal amount thereof due such Lender plus accrued and unpaid interest and fees due such Lender, which interest in the Loans will be assigned by such Lender when such principal, interest and fees are paid to such Lender. In the event that Agent or such Eligible Assignee elects to require

any Lender to assign its interest to Agent pursuant to this Section 11.1(k)(ii), Agent will so notify such Lender in writing within forty-five (45) days following such Lender’s denial, and such Lender will assign its interest to Agent or such Eligible Assignee no later than five (5) calendar days following receipt of such notice.

11.2 Set-off and Sharing of Payments

In addition to any rights and remedies now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence and during the continuation of any Event of Default, each Lender is hereby authorized by the Credit Parties at any time or from time to time, to the fullest extent permitted by law, with notice to Agent and without prior notice to Borrower or any other Person other than Agent (such notice being hereby expressly waived) to set off and to appropriate and to apply any and all (a) balances (general or special, time or demand, provisional or final) held by such Lender at any of its offices for the account of any Credit Party (regardless of whether such balances are then due to any Credit Party), and (b) other Property at any time held or owing by such Lender to or for the credit or for the account of any Credit Party, against and on account of any of the Obligations which are not paid when due; provided, that no Lender or any such holder shall exercise any such right without prior written notice to Agent. Any Lender that has exercised its right to set-off or otherwise has received any payment on account of the Obligations shall, to the extent the amount of any such set off or payment exceeds its Pro Rata Share of payments obtained by all of the Lenders on account of such Obligations, purchase for cash (and the other Lenders or holders of the Loans shall sell) participations in each such other Lender’s or holder’s Pro Rata Share of Obligations as would be necessary to cause such Lender to share such excess with each other Lenders or holders in accordance with their respective Pro Rata Shares; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such purchasing Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery. Each Credit Party agrees, to the fullest extent permitted by law, that (a) any Lender or holder may exercise its right to set-off with respect to amounts in excess of its Pro Rata Share of the Obligations and may sell participations in such excess to other Lenders and holders, and (b) any Lender so purchasing a participation in the Loans made or other Obligations held by other Lenders may exercise all rights of set-off, bankers’ lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans and other Obligations in the amount of such participation.

11.3 Disbursement of Funds under Revolving Facility

Agent may, on behalf of Lenders, disburse funds to Borrower for Advances requested. Each Lender shall reimburse Agent on demand for its Pro Rata Share of all funds disbursed on its behalf by Agent, or if Agent so requests, each Lender shall remit to Agent its Pro Rata Share of any Advance before Agent disburses such Advance to Borrower. If Agent so elects to require that funds be made available prior to disbursement to Borrower, Agent shall advise each Lender by telephone, telex or telecopy of the amount of such Lender’s Pro Rata Share of such requested Advance no later than one (1) Business Day prior to the funding date applicable thereto, and each such Lender shall pay Agent such Lender’s Pro Rata Share of such requested Loan, in same day funds, by wire transfer to Agent’s account not later than 2:00p.m. (New York City time). If Agent shall have disbursed funds to Borrower on behalf of any such Lender fails to pay the

amount of its Pro Rata Share forthwith upon Agent’s demand, Agent shall promptly notify Borrower, and Borrower shall immediately repay such amount to Agent. Any repayment by Borrower required pursuant to this Section 11.3 shall be without premium or penalty. Nothing in this Section 11.3 or elsewhere in this Agreement or the other Loan Documents, including, without limitation, the provisions of Section 11.4, shall be deemed to require Agent to advance funds on behalf of any Lender or to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that Agent or Borrower may have against any Lender as a result of any default by such Lender hereunder.

11.4 Settlements; Payments; and Information

(a) Advances; Payments; Interest and Fee Payments.

(i) The amount of outstanding Loans pursuant to Advances may fluctuate from day to day through Agent’s disbursement of funds to, and receipt of funds from, Borrower. In order to minimize the frequency of transfers of funds between Agent and each Lender, notwithstanding terms to the contrary set forth in Section 11.3, Advances and repayments thereof may be settled according to the procedures described in Sections 11.4(a)(ii) and 11.4(a)(iii). Notwithstanding these procedures, each Lender’s obligation to fund its Pro Rata Share of any Advances made by Agent to Borrower will commence on the date such Advances are made by Agent. Nothing contained in this Agreement shall obligate a Lender to make an Advance at any time any Default or Event of Default exists. All such payments will be made by such Lender without set-off, counterclaim or deduction of any kind.

(ii) Once each week, or more frequently (including daily), if Agent so elects (each such day being a “Settlement Date”), Agent will advise each Lender by 1:00p.m. (New York City time) on a Business Day by telephone, telex or telecopy of the amount of each such Lender’s Pro Rata Share of the outstanding Advances. In the event payments are necessary to adjust the amount of such Lender’s share of the Advances to such Lender’s Pro Rata Share of the Advances, the party from which such payment is due will pay the other party, in same day funds, by wire transfer to the other’s account not later than 2:00p.m. (New York City time) on the Business Day following the Settlement Date.

(iii) On the first Business Day of each month (“Interest Settlement Date”), Agent will advise each Lender by telephone or facsimile of the amount of interest and fees charged to and collected from Borrower for the preceding month in respect of the applicable Loans. Provided that such Lender has made all payments required to be made by it under this Agreement, Agent will pay to such Lender, by wire transfer to such Lender’s account (as specified by such Lender on Schedule A of this Agreement as amended by such Lender from time to time after the date hereof pursuant to the notice provisions contained herein or in the applicable Lender Addition Agreement) not later than 2:00p.m. (New York City time) on the next Business Day following the Interest Settlement Date, such Lender’s share of such interest and fees.

(b) Availability of Lenders’ Pro Rata Share.

(i) Unless Agent has been notified by a Lender prior to any proposed funding date of such Lender’s intention not to fund its Pro Rata Share of an Advance requested by Borrower, Agent may assume that such Lender will make such amount available to Agent on the proposed funding date or the Business Day following the next Settlement Date, as applicable; provided, however, nothing contained in this Agreement shall obligate a Lender to make an Advance at any time any Default or Event of Default exists. If such amount is not, in fact, made available to Agent by such Lender when due, Agent will be entitled to recover such amount on demand from such Lender without set-off, counterclaim or deduction of any kind.

(ii) Nothing contained in this Section 11.4(b) will be deemed to relieve a Lender of its obligation to fulfil its commitments or to prejudice any rights Agent or Borrower may have against such Lender as a result of any default by such Lender under this Agreement.

(c) Return of Payments.

(i) If Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or will be received by Agent from any Credit Party and such related payment is not received by Agent, then Agent will be entitled to recover such amount from such Lender without set-off, counterclaim or deduction of any kind.

(ii) If Agent determines at any time that any amount received by Agent under this Agreement must be returned to any Credit Party or paid to any other Person pursuant to any Debtor Relief Law or otherwise, then, notwithstanding any other term or condition of this Agreement, Agent will not be required to distribute any portion thereof to any Lender. In addition, each Lender will repay to Agent on demand any portion of such amount that Agent has distributed to such Lender, together with interest at such rate, if any, as Agent is required to pay to Borrower or such other Person, without set-off, counterclaim or deduction of any kind.

11.5 Dissemination of Information

Upon request by a Lender, Agent will distribute promptly to such Lender, unless previously provided by any Credit Party to such Lender, copies of all notices, schedules, reports, projections, financial statements, agreements and other material and information, including, without limitation, financial and reporting information received from the Credit Parties or generated by a third party (and excluding only internal information generated by CapitalSource for its own use as a Lender or as Agent), as provided for in this Agreement and the other Loan Documents as received by Agent. Agent shall not be liable to any of the Lenders for any failure to comply with its obligations under this Section 11.5, except to the extent that such failure is attributed to Agent’s gross negligence or wilful misconduct and results in demonstrable damages to such Lender as determined, in each case, by a court of competent jurisdiction on a final and non-appealable basis.

XII. MISCELLANEOUS

12.1 Governing Law and Enforcement

This Agreement is governed by English law.

12.2 Jurisdiction of English courts

(a) The courts of England have exclusive jurisdiction to settle any dispute arising out of or in connection with this Agreement (including a dispute regarding the existence, validity or termination of this Agreement) (a “Dispute”).

(b) The Parties agree that the courts of England are the most appropriate and convenient courts to settle Disputes and accordingly no Party will argue to the contrary.

(c) This Section 12.2 is for the benefit of the Lender Parties only. As a result, no Lender Party shall be prevented from taking proceedings relating to a Dispute in any other courts with jurisdiction. To the extent allowed by law, the Lender Parties may take concurrent proceedings in any number of jurisdictions.

12.3 Service of process

Without prejudice to any other mode of service allowed under any relevant law, each Credit Party (other than a Credit Party incorporated in England and Wales):

(a) irrevocably appoints Borrower at its registered office, FAO Legal Department as its agent for service of process in relation to any proceedings before the English courts in connection with any Loan Document and the Borrower by its execution of this Agreement, accepts that appointment); and

(b) agrees that failure by a process agent to notify the relevant Credit Party of the process will not invalidate the proceedings concerned.

(c) If any person appointed as process agent is unable for any reason to act as agent for service of process, the Borrower (on behalf of all the Credit Parties) must immediately (and in any event within 5 days of such event taking place) appoint another agent on terms acceptable to the Agent. Failing this, the Agent may appoint another agent for this purpose.

Evolving Systems, Inc., Telecom Software Enterprises, LLC and Evolving Systems Holdings, Inc. each expressly agrees and consents to the provisions of Section 12.2 and 12.3.

12.4 Successors and Assigns; Assignments and Participations

(a) Subject to Section 12.4(h), each Lender may, at any time and from time to time, assign all or any portion of its rights and delegate all or a portion of its obligations under

this Agreement and the other Loan Documents in a minimum amount of $1,000,000 (or 100% of any remaining commitment less than $1,000,000) (including all of its rights and obligations with respect to the Loans) to one or more Eligible Assignees (each, a “Transferee”) with the prior written consent of Agent and, to the extent no Default or Event of Default shall have occurred and be continuing, with the prior written consent of Borrower (which consent of Borrower shall not be unreasonably withheld, delayed or conditions, or required if any Default or Event of Default exists); provided, that such Transferee and such assigning Lender shall execute and deliver to Agent for acceptance and recording in the Register, a Lender Addition Agreement, which shall be in form and substance acceptable to Agent in its Permitted Discretion. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Lender Addition Agreement, (i) the Transferee thereunder shall be a party hereto and, to the extent provided in such Lender Addition Agreement, have the same rights, benefits and obligations of a Lender hereunder, (ii) the assigning Lender shall be relieved of its obligations hereunder with respect to its Commitment or assigned portion thereof, as the case may be, to the extent that such obligations shall have been expressly assumed by the Transferee pursuant to such Lender Addition Agreement (and, in the case of a Lender Addition Agreement covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such assigning Lender shall cease to be a party hereto but shall nevertheless continue to be entitled to the benefits of Sections 12.6 and 12.9). Borrower hereby acknowledges and agrees that any assignment will give rise to a direct obligation of Borrower to the Transferee and that the Transferee shall be a “Lender” hereunder and under the other Loan Documents. Except as provided in Section 12.4(h), no Lender will assign all or any portion of its Loans and/or Commitments unless such Lender also assigns its proportionate share of its “Loans” and/or “Commitments” under (and as defined in) the Term Loan Agreement. Notwithstanding anything to the contrary contained in this Section 12.4, no Transferee shall be entitled to the benefits of Section 13.1 unless such Transferee is a “United States Person” (as defined in Section 13.1(f)) or is a resident of the United Kingdom for UK Tax purposes.

(b) Each Lender at any time may sell participations in all or any part of its rights and obligations under this Agreement and the other Loan Documents (including all of its rights and obligations with respect to the Loans) to one or more Persons (each, a “Participant”). In the event of any such sale by a Lender of a participation to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan (and any Note evidencing such Loan) for all purposes under this Agreement and the other Loan Documents and Borrower and Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. Any agreement pursuant to which any Lender shall sell any such participation shall provide that such Lender shall retain the sole right and responsibility to exercise such Lender’s rights and enforce each Credit Party’s obligations hereunder, including the right to consent to any amendment, supplement, modification or waiver of any provision of this Agreement or any of the other Loan Documents; provided, that such participation agreement may provide that such Lender will not agree, without the consent of the Participant, to any amendment, supplement, modification or waiver to the extent resulting in: (i) any reduction in the principal amount, interest rate or fees payable with respect to any Loan in which such Participant participates; (ii) any extension of the date fixed for any payment of principal, interest or fees payable with respect to any Loan in which such Participant participates;

and (iii) any release of all or substantially all of the Collateral (other than in accordance with the terms of this Agreement or the other Loan Documents). The Credit Parties hereby acknowledge and agree that the Participant under each participation shall, solely for the purposes of Sections 10.5, 12.6 and 12.9 of this Agreement, be considered to be a “Lender” hereunder. Notwithstanding anything to the contrary contained in this Section 12.4, no Participant shall be entitled to the benefits of Section 13.1 unless such Participant is a “United States Person” (as defined in Section 13.1(f)) or is a resident of the United Kingdom for UK Tax purposes.

(c) Agent, on behalf of Borrower, shall maintain at its address referred to in Section 12.7 a copy of each Lender Addition Agreement delivered to it and the Register for the recordation of the names and addresses of the Lenders and the Commitment of, and the principal amount of the Loans owing to, and the Notes, if any, evidencing such Loans owned by, each Lender from time to time. Anything contained in this Agreement to the contrary notwithstanding, each of the Credit Parties, Agent and the Lenders shall treat each Person whose name is recorded in such Register as the owner of the Loans, the Notes and the Commitments recorded therein for all purposes of this Agreement. The Register shall be available for inspection by Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Notwithstanding anything in this Agreement to the contrary, no assignment under Section 12.4(a) of any rights or obligations under or in respect of the Loans or the Notes evidencing such Loans shall be effective unless and until (i) Agent shall have recorded the assignment pursuant to Section 12.4(c) and (ii) the assignor Lender or the Transferee has paid to Agent a processing fee (not at the expense of any Credit Party) in the amount of $3,500 (provided no such processing fee shall be required to be paid in connection with an assignment by a Lender to another Lender, an Eligible Assignee that is an Affiliate of such Lender or a Related Fund of such Lender). Upon its receipt of a Lender Addition Agreement executed by an assigning Lender and an Transferee, Agent shall (i) promptly accept such Lender Addition Agreement and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give prompt notice of such acceptance and recordation to the Lenders and Borrower. On or prior to such effective date, the assigning Lender shall surrender any outstanding Notes held by it all or a portion of which are being assigned, and Borrower, at its own expense, shall, upon the request of Agent, the assigning Lender or the Transferee, as applicable, execute and deliver to Agent, within five (5) Business Days of any request, new Notes to reflect the interest held by the assigning Lender and its Transferee.

(e) Except as otherwise provided in this Section 12.4, no Lender shall, as between Borrower and that Lender, be relieved of any of its obligations hereunder as a result of any sale, assignment, transfer or negotiation of, or granting of participations in, all or any part of the Loans or other Obligations owed to such Lender. Each Lender may furnish any information concerning the Credit Parties in the possession of that Lender from time to time to assignees and participants (including prospective assignees and participants), subject to confidentiality requirements, if any, hereunder.

(f) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time create a security interest in all or any portion of its rights under this

Agreement, including, without limitation, the Loans owing to it and the Notes held by it and the other Loan Documents and its rights in the Collateral.

(g) Each Credit Party agrees to provide commercially reasonable efforts to assist any Lender in assigning or selling participations in all or any part of any Loans made by such Lender to a potential Transferee or Participant identified by such Lender.

(h) Notwithstanding anything in the Loan Documents to the contrary, (i) CapitalSource and its Affiliates shall not be required to execute or deliver a Lender Addition Agreement in connection with any transaction involving CapitalSource and any of its Affiliates, or the lenders or funding or financing sources of CapitalSource or any of its Affiliates, (ii) subject to the provisions at the end of this paragraph, no lender to or Affiliate, funding or financing source of CapitalSource or any of its Affiliates shall be considered a Transferee, and (iii) there shall be no limitation or restriction on (A) the ability of CapitalSource or any of its Affiliates to assign or otherwise transfer any Loan Document, Commitment or Obligation to any such Affiliate or lender or financing or funding source or (B) any such lender’s or funding or financing source’s ability to assign or otherwise transfer any Loan Document, Commitment or Obligation; provided, however, CapitalSource shall continue to be liable as a “Lender” under the Loan Documents unless such Affiliate, lender or funding or financing source executes and delivers a Lender Addition Agreement and thereby becomes a “Lender.”

(i) The Loan Documents shall be binding upon and inure to the benefit of each Lender, Agent, each Transferee, each Participant (to the extent expressly provided herein only) and all future holders of the Loans, the Notes, the Obligations and/or any of the Collateral, and each of their respective successors and assigns. Each Loan Document shall be binding upon the Persons other than Lenders and Agent that are parties thereto and their respective successors and assigns; provided that, no such Person shall assign, delegate or transfer any Loan Document or any of its rights or obligations thereunder without the prior written consent of Agent and each Lender. No rights are intended to be created under any Loan Document for the benefit of any third party donee, creditor or incidental beneficiary of any Credit Party. Nothing contained in any Loan Document shall be construed as a delegation to Agent or any Lender of any other Person’s duty of performance.

12.5 Reinstatement; Application of Payments

To the extent that any payment made or received with respect to the Obligations is subsequently invalidated, determined to be fraudulent or preferential, set aside, defeased or required to be repaid to a trustee, debtor in possession, receiver, administrator, custodian or any other similar Person under any Debtor Relief Law, common law or equitable cause or any other law, then the Obligations intended to be satisfied by such payment shall be revived and shall continue as if such payment had not been received by Agent or any Lender and the Liens created by the Security Documents shall be revived automatically without any action on the part of any party hereto and shall continue as if such payment had not been received by Agent or such Lender. Except as specifically provided in this Agreement, any payments with respect to the Obligations received shall be credited and applied in such manner and order as Agent shall decide in its sole discretion.

12.6 Indemnity

The Credit Parties, jointly and severally, hereby indemnify Agent and each Lender, and their respective Affiliates, managers, members, officers, employees, agents, representatives, successors, assigns, accountants and attorneys (collectively, the “Indemnified Persons”) from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including, without limitation, reasonable fees and disbursements of counsel and in-house documentation and diligence fees and legal expenses) which may be imposed on, incurred by or asserted against any Indemnified Person with respect to or arising out of, or in any litigation, proceeding or investigation instituted or conducted by any Person with respect to any aspect of, or any transaction contemplated by, or any matter related to, any Loan Document, any Term Loan Document, any Related Document or any agreement, document or transaction contemplated thereby, whether or not such Indemnified Person is a party thereto, except to the extent a final and nonappealable order of judgment binding on such Indemnified Person of a court of competent jurisdiction determines the same arose out of the gross negligence or wilful misconduct of such Indemnified Person. If any Indemnified Person uses in-house counsel for any purpose for which the Credit Parties are responsible to pay or indemnify, the Credit Parties expressly agree that their indemnification obligations include reasonable charges for such work commensurate with the reasonable fees that would otherwise be charged by outside legal counsel selected by such Indemnified Person in its sole discretion for the work performed. Agent agrees to give Borrower reasonable notice of any event of which Agent becomes aware for which indemnification may be required under this Section 12.6, and Agent may elect (but is not obligated) to direct the defense thereof. Any Indemnified Person may take such actions as it deems necessary and appropriate to investigate, defend or settle any event or take other remedial or corrective actions with respect thereto as may be necessary for the protection of such Indemnified Person or the Collateral; provided, however, that the Indemnified Person shall not settle, compromise or admit any liability or wrongdoing without the prior written consent of the Borrower (which consent shall not be unreasonably withheld or delayed). Notwithstanding the foregoing, if any insurer agrees to undertake the defense of an event (an “Insured Event”), Agent agrees not to exercise its right to select counsel to defend the event if that would cause Borrower’s insurer to deny coverage; provided, however, that each Indemnified Person reserves the right to retain counsel to represent such Indemnified Person with respect to an Insured Event at its sole cost and expense. To the extent that Agent or any Lender obtains recovery from a third party other than an Indemnified Person of any of the amounts that the Credit Parties have paid to Agent or any Lender pursuant to the indemnity set forth in this Section 12.4, then Agent and/or any such Lender shall promptly pay to Borrower the amount of such recovery. Without limiting any of the foregoing, the Credit Parties, jointly and severally, indemnify the Indemnified Parties for all claims for brokerage fees or commissions by any person claiming by, through or under any Credit Party or Affiliate thereof which may be made in connection with respect to any aspect of, or any transaction contemplated by or referred to in, or any matter related to, any Loan Document, any of the Term Loan Documents, any Related Document or any other agreement, document or transaction contemplated thereby.

12.7 Notice

Subject to Section 12.3, any notice or request under any Loan Document shall be given to any party to this Agreement at such party’s address set forth beneath its signature on the signature page to this Agreement, or at such other address as such party hereafter may specify in a notice given in the manner required under this Section 12.7. Any notice or request hereunder shall be given only by, and shall be deemed to have been received upon (each, a “Receipt”): (i) registered or certified mail, return receipt requested, on the date on which such notice or request is received as indicated in such return receipt, (ii) delivery by a nationally recognized overnight courier, one (1) Business Day after deposit with such courier, or (iii) facsimile or electronic transmission, in each case upon telephone or further electronic communication from the recipient acknowledging receipt (whether automatic or manual from recipient), as applicable.

12.8 Severability; Headings; Counterparts

If any provision of any Loan Document is adjudicated to be invalid under applicable laws or regulations, such provision shall be inapplicable to the extent of such invalidity without affecting the validity or enforceability of the remainder of the Loan Documents which shall be given effect so far as possible. The headings in the Loan Documents are intended for convenience and reference only and shall not affect the meaning or interpretation of the Loan Documents. The Loan Documents may be executed in one or more counterparts (which taken together, as applicable, shall constitute one and the same instrument) and by facsimile transmission, which facsimile signatures shall be considered original executed counterparts. Each party to this Agreement agrees that it will be bound by its own facsimile signature and that it accepts the facsimile signature of each other party.

12.9 Expenses

The Credit Parties hereby jointly and severally agree to pay on demand, whether or not the Closing occurs, all reasonable costs and expenses incurred by Agent, Lenders and/or their Affiliates, including, without limitation, documentation and diligence fees and expenses, all search, audit, appraisal, recording, professional and filing fees and expenses and all other out-of-pocket charges and expenses, and reasonable attorneys’ fees and expenses, (i) in any effort to enforce, protect or collect payment of any Obligation or to enforce any Loan Document, any Related Document or any related agreement, document or instrument, (ii) in connection with entering into, negotiating, preparing, reviewing and executing the Loan Documents, the Term Loan Documents, the Related Documents and/or any related agreements, documents or instruments, (iii) arising in any way out of the administration of the Obligations or the taking or refraining from taking by Agent or any Lender of any action requested by any Credit Party, (iv) in connection with instituting, maintaining, preserving, enforcing and/or foreclosing on the Liens in any of the Collateral or securities pledged under the Loan Documents, whether through judicial proceedings or otherwise, (v) in defending or prosecuting any actions, claims or proceedings arising out of or relating to Agent’s and/or Lenders’ transactions with the Credit Parties, (vi) in seeking, obtaining or receiving any advice with respect to its rights and obligations under any Loan Document, any Term Loan Document, any Related Document and any related agreement, document or instrument, (vii) arising out of or relating to any Default or Event of Default or as a result thereof, (viii) in connection with all actions, visits, audits and

inspections undertaken by Agent or Lenders or their Affiliates pursuant to the Loan Documents, the Term Loan Documents, any Related Document, and/or (ix) in connection with any modification, restatement, supplement, amendment, waiver or extension of any Loan Document, any Term Loan Document, any Related Document and/or any related agreement, document or instrument. All of the foregoing shall be charged to Borrower’s account and shall be part of the Obligations. If Agent, any Lender or any of their Affiliates uses in-house counsel for any purpose under any Loan Document for which the Credit Parties are responsible to pay or indemnify, the Credit Parties expressly agree that their Obligations include reasonable charges for such work commensurate with the reasonable fees that would otherwise be charged by outside legal counsel selected by Agent, such Lender or such Affiliate in its sole discretion for the work performed. Without limiting the foregoing, Borrower shall pay all taxes (other than taxes based upon or measured by a Lender’s income or revenues or any personal property tax), if any, in connection with the issuance of any Note and the filing and/or recording of any documents and/or financing statements. Notwithstanding anything to the contrary contained herein or in any other Loan Document, in no event shall the Credit Parties be liable for any costs or expenses relating to or arising out of the syndication or participation of the Loan, unless such syndication or participation is at the request of any Credit Party.

12.10 Entire Agreement

This Agreement and the other Loan Documents to which the Credit Parties are parties constitute the entire agreement between and among the Credit Parties, Agent and Lenders with respect to the subject matter hereof and thereof, and supersede all prior agreements and understandings (including, without limitation, the letter dated on or about September 8, 2005) relating to the subject matter hereof or thereof. Execution of this Agreement by the Credit Parties constitutes a full, complete and irrevocable release of any and all claims which any Credit Party may have at law or in equity in respect of all prior discussions and understandings, oral or written, relating to the subject matter of this Agreement and the other Loan Documents. Each party hereto acknowledges that it has been advised by counsel in connection with the negotiation and execution of this Agreement and is not relying upon oral representations or statements inconsistent with the terms and provisions hereof. The obligations of the Credit Parties and the rights of the Lenders and the Agent under this Agreement and the Loan Documents shall be in addition to any obligation and rights under the Term Loan Documents.

12.11 Approvals and Duties

Unless expressly provided herein to the contrary, any approval, consent, waiver or satisfaction of Agent or Lenders with respect to any matter that is the subject of any Loan Document may be granted or withheld by Agent or Lenders, as applicable, in their sole and absolute discretion. Other than Agent’s duty of reasonable care with respect to Collateral delivered pursuant to the Loan Documents in accordance with applicable law (to the extent not waivable), Agent and Lenders shall have no responsibility for or obligation or duty with respect to any of the Collateral or any matter or proceeding arising out of or relating thereto, including, without limitation, any obligation or duty to collect any sums due in respect thereof or to protect or preserve any rights pertaining thereto.

12.12 Confidentiality and Publicity

(a) Each Credit Parties agrees, and agrees to cause each of its Subsidiaries, (i) except to the extent required by applicable law or regulations (in which case, except in connection with the Securities Act and the Securities Exchange Act, as amended and the rules thereunder, each Credit Party shall, and shall cause its Subsidiaries to, use its best efforts to obtain confidential treatment of such information), not to transmit or disclose any provision of any Loan Document to any Person (other than to such Credit Party’s directors, advisors, counsel, accountants, officers and employees on a need-to-know basis), in any such case without Agent’s prior written consent, and (ii) to inform all Persons receiving information related to the Loan Documents, except through disclosure pursuant to the Securities Act and the Securities Exchange Act, as amended, and the rules thereunder, of the confidential nature of the Loan Documents and to direct them not to disclose the same to any other Person, and to require each of them to be bound by these provisions. Except for filings submitted pursuant to the Securities Act and the Securities Exchange Act, and the rules thereunder, the Credit Parties shall provide in writing any materials that the Credit Parties or any of their Subsidiaries prepare that contain Agent’s or any Lender’s name or describe or refer to any Loan Document, any of the terms thereof or any of the transactions contemplated thereby prior to its use, disclosure or distribution, and Agent and each Lender reserves the right to review and approve in advance (which approval shall not be unreasonably withheld or delayed) all such materials. The Credit Parties shall not, and shall not permit any of their Subsidiaries to, use either Agent’s or any Lender’s name (or the name of any of Agent’s or any Lender’s Affiliates) in connection with any of its Business; provided, that Borrower may disclose the Lenders’ names, the aggregate principal amount of the Loans outstanding and other principal terms of such Loans to (x) its shareholders and other equity owners and prospective purchasers of debt or equity securities of Borrower and (y) Governmental Authorities regulating the Business in accordance with applicable legal requirements. Nothing contained in any Loan Document is intended to permit or authorize any Credit Party or any of its Subsidiaries to contract on behalf of Agent or any Lender. Notwithstanding the foregoing, copies of the Loan Documents and information concerning the applicable provisions of such Loan Documents may be delivered to each holder of the Subordinated Notes in connection with matters relating to the Seller Subordination Agreement.

(b) Agent and each Lender agree to exercise their best efforts to maintain in confidence, in accordance with its customary procedures for handling confidential information, all non-public information that any Credit Party or Subsidiary thereof furnishes to Agent or such Lender on a confidential basis clearly identified as such (“Confidential Information”), other than any such Confidential Information that becomes generally available to the public other than as a result of a breach by Agent or any Lender of its obligations hereunder or that is or becomes available to Agent or any Lender from a source other than a Credit Party and that is not, to the actual knowledge of the recipient thereof, subject to obligations of confidentiality with respect thereto; provided, however, that Agent and each Lender shall, in any event, have the right to deliver copies of any such information, and to disclose any such information, to:

(i) its affiliates, lenders, funding or financing sources (or its affiliates’ or lenders’ funding or financing sources), portfolio management services and partners that are obligated to maintain the confidentiality of such Confidential Information;

(ii) directors, officers, trustees, employees, agents, attorneys, professional consultants and rating agencies;

(iii) any other Lender and any successor Agent;

(iv) (A) subject to provisions substantially similar to those contained in this Section 12.10 any potential Transferee or Participant or (B) any Person if the disclosure consists of general portfolio information and does not identify any Credit Party specifically by name;

(v) any regulatory authority or examiner, or any insurance industry association, regulating or having jurisdiction over Agent or any Lender and requiring or requesting such disclosure; and

(vi) any other Person to which such delivery or disclosure may be necessary (A) in compliance with any applicable law, rule, regulation or order, (B) in response to any subpoena or other legal process or informal investigative demand, (C) in connection with any litigation to which Agent or such Lender is a party, or (D) in connection with the exercise or enforcement, or potential exercise or enforcement, of any of the rights and/or remedies of Agent and/or the Lenders under this Agreement and the other Loan Documents at any time during the existence of an Event of Default.

Should Agent or any Lender be required to disclose any such information by virtue of a subpoena or similar process by any court or any tribunal, or agency pursuant to items (v) or (vi) above, then Agent or such Lender shall promptly notify the applicable Credit Party thereof so as to allow such Credit Party, at its sole cost and expense, to seek a protective order or to take any other appropriate action to protect its rights. Further, the foregoing notwithstanding, the Credit Parties agree that Agent, any Lender or any Affiliate of Agent or any Lender may (i) disclose a general description of transactions arising under the Loan Documents, the Term Loan Documents, and the Related Documents for advertising, marketing or other similar purposes, and (ii) use any Credit Party’s name, logo or other indicia germane to such party in connection with such advertising, marketing or other similar purposes.

(c) The obligations of Agent and Lenders under this Section 12.10 shall supersede and replace the obligations of Agent and Lenders under any confidentiality agreement in respect of the financing evidenced hereby executed and delivered by Agent or any Lender prior to the date hereof.

12.13 No Consequential Damages

No party to this Agreement or any other Loan Document, nor any agent or attorney of such party or any Lender, shall be liable to any other party to this Agreement or any other Person on any theory of liability for any special, indirect, consequential or punitive damages.

XIII. TAXES

13.1 Taxes

(a) Subject to this Section 13.1, any and all payments by Borrower or any other Credit Party to each Lender or Agent under this Agreement or any other Loan Document shall be made free and clear of, and without deduction or withholding for, any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender and Agent, such taxes (including income taxes or franchise taxes) as are imposed on or measured by the net income of such Lender or Agent, respectively, by the jurisdiction under the laws of which such Lender or Agent, as the case may be, is organized or maintains a Lending Office or other taxable presence or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”).

(b) In addition, Borrower and the other Credit Parties shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as “Other Taxes”).

(c) Subject to this Section 13.1, the Credit Parties shall indemnify and hold harmless each Lender and Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 13.1) paid by such Lender or Agent and any liability (including penalties, interest, additions to tax and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted except in the case of Taxes or Other Taxes incurred due to the gross negligence or wilful misconduct of such Lender or Agent. Payment under this indemnification shall be made within ten (10) days from the date any Lender or Agent makes written demand therefor.

(d) If any Credit Party shall be required by law to deduct or withhold any Taxes or Other Taxes from or in respect of any sum payable hereunder to any Lender or Agent, then, subject to this Section 13.1:

(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 13.1), such Lender or Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made;

(ii) such Credit Party shall make such deductions; and

(iii) such Credit Party shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(e) Within ten (10) days after the date of any payment by any Credit Party of Taxes or Other Taxes, Borrower shall furnish to Agent (and the applicable Lender) the original

or a certified copy of a receipt evidencing payment thereof, or other evidence of payment satisfactory to Agent (and the applicable Lender).

(f) No Lender shall be entitled to any additional amounts solely in respect of a deduction or withhold for or on account of United Kingdom Taxes (a “UK Withholding Tax Deduction”) in respect of interest payable by the Borrower hereunder, if on the date on which the payment falls due, the payment could have been made to such Lender without a UK Withholding Tax Deduction if such Lender was entitled under a Treaty to a full exemption from UK Withholding Tax Deductions in respect of interest payable hereunder, but on such date such Lender is not or has ceased to be entitled to a full exemption from UK Withholding Tax Deductions other than as a result of any change after the Closing Date (or, if later, the date it became a Lender hereunder) in any existing law, regulation, treaty or directive or in the interpretation or application thereof.

(g) Notwithstanding any other provision of any Loan Document but subject to the next following sentence, if at any time after the Closing or the making of any Advance or funding of the Term Loan (x) any change in any existing law, regulation, treaty or directive or in the interpretation or application thereof, (y) any new law, regulation, treaty or directive enacted or any interpretation or application thereof, or (z) compliance by Agent or any Lender with new request or directive (whether or not having the force of law) from any Governmental Authority: (i) subjects Agent or such Lender to any tax, levy, impost, deduction, assessment, charge or withholding imposed by any taxing authority with respect to any Loan Document, or changes the basis of taxation of payments to Agent, for its own account and/or for the benefit of Lenders, of any amount payable thereunder (except in each case, for net income taxes imposed generally by any taxing authority under the law of the jurisdiction where a Lender or the Agent is organized or where it has a Lending Office or its principal place of business (or, if different, in which, other than by reason of its execution and performance of the Loan Documents, it is treated as resident for tax purposes) or, in the case of any Lender, in which its applicable lending office is located, with respect to interest or commitment fees or other fees payable hereunder or changes in the rate of tax on the overall net income of Agent and/or such Lender), or (ii) imposes on Agent or Lenders any other condition or increased cost (not related to taxation) in connection with the transactions contemplated thereby or participations therein; and the result of any of the foregoing is to increase the cost to Agent or Lenders of making or continuing or maintaining any Loan hereunder or to reduce any amount receivable hereunder, then, in any such case, the Credit Parties shall promptly pay to the Agent, for its own account and/or for the benefit of Lenders, any additional amounts necessary to compensate Agent and each Lender, on an after-tax basis, for such additional cost or reduced amount as determined by Agent and/or such Lender (acting reasonably and in good faith). The Credit Parties shall not be required to pay any amounts as provided in the preceding sentence, (i) to the extent Agent or such Lender shall have already been compensated for such increased cost or reduced amount under Section 2.11 or 2.12 of this Agreement, (ii) to the extent such increased cost or reduced amount is attributable to the wilful breach by Agent or such Lender (or an Affiliate of Agent or such Lender), as applicable, of any law or regulation, (iii) to the extent such increased cost or reduced amount is attributable to a withholding for or on account of Tax or (iv) to the extent Agent or such Lender shall have already been compensated, or is not entitled to compensation, for such increased cost or reduced amount under Section 13.1(c). If Agent or any Lender becomes entitled to claim any additional amounts pursuant to this Section 13.1 it shall reasonably promptly after obtaining knowledge

thereof notify Borrower of the event by reason of which Agent or such Lender has become so entitled, and each such notice of additional amounts payable pursuant to this Section 13.1 submitted by Agent or such Lender to the Credit Parties shall, absent manifest error, be final, conclusive and binding for all purposes.

(h) If at any time the Borrower or any other Credit Party is required by law to make any deduction or withholding from any sum payable by it under this Agreement or any other Loan Document (or if subsequently there is any change in the rates at which or the manner in which such deductions or withholdings are calculated), it shall promptly notify Agent upon becoming aware of the same. In addition, each Lender shall promptly notify Agent upon becoming aware of any circumstances as a result of which Borrower or any other Credit Party is or would be required to make any deduction or withholding from any sum payable by it under this Agreement or under any other Loan Document (or if subsequently there is or would be any change in the rates at which or the manner in which such deductions or withholdings are calculated), whether as a result of such Lender ceasing to beneficially own interest payable hereunder or otherwise. If Agent receives such a notification from a Lender it shall promptly notify the Borrower. Any Lender which ceases to be a Treaty Lender by reason of an action taken by such Lender or by reason of a failure by such Lender to take any action as required by this Agreement shall, upon becoming aware of such action or failure, also promptly notify Agent and the Borrower of its change in status, the date of such change and the reason for its change in status. The Borrower or any Credit Party, as appropriate, shall pay the full amount deducted to the relevant taxing or other authority in accordance with the applicable law and promptly provide an original tax certificate of withholding to the Agent or relevant Lender (which, in the case of a withholding under United Kingdom tax legislation, is in the form of a duly completed Form R185), as appropriate (or other evidence reasonably satisfactory to such Person).

(i) Upon written request by Borrower, each Lender that is not a “United States Person” within the meaning of Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to Borrower and Agent two (2) copies of each U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or any subsequent versions thereof or successors thereto, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a Form W-8BEN, or any subsequent versions thereof or successors thereto (and a certificate representing that such Non-U.S. Lender is not a “bank” for purposes of Section 881(c) of the Code, is not a ten (10%) percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of Borrower and is not a controlled foreign corporation related to Borrower (within the meaning of Section 864(d)(4) of the Code)), properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement. In addition, each Non-U.S. Lender shall deliver such forms (or other forms or documents to the extent required) promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender or upon any changes in the forms or documents required hereunder for establishing that payments to the Non-US Lender are exempt from withholding. Each Non-U.S. Lender shall promptly notify Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose).

Notwithstanding any other provision of this section, a Non-U.S. Lender shall not be required to deliver any form pursuant to this subsection that such Non-U.S. Lender is not legally able to deliver.

(j) No Credit Party shall be required to pay any additional amounts in respect of United States Federal income tax pursuant to this Section 13.1 to Agent or to any Lender for the account of any Lending Office of such Lender if the obligation to pay such additional amounts would not have arisen but for a failure by such Lender to deliver the forms or other documents under Section 13.1(i) in respect of such Lending Office.

(k) To the extent that the Borrower or another Credit Party reasonably determines that (i) Agent and/or any Lender may recover Taxes deduction from payments made by Borrower or such Credit Party under any Loan Document to the extent Borrower or such Credit Party shall have paid additional amounts in respect of such Taxes under Section 13.1(d) or (ii) a withholding or deduction for or on account of taxes may be avoided or reduced if, in either case, Agent or a Lender completes certain procedural formalities and/or provides properly completed and executed documentation prescribed by applicable law, Agent or such Lender shall within a reasonable timeframe cooperate with Borrower to complete such procedural formalities and/or provide such documentation to the Borrower (in each case, upon the Borrower’s reasonable request and at the Borrower’s sole cost and expense); provided that Agent or such Lender, as the case may be, determines in its sole, good faith reasonable judgment that completing such procedural formalities and/or providing such documentation will not disadvantage or prejudice such Agent or Lender in any manner.

(l) If the United Stated Internal Revenue Service or any other Governmental Authority of the United States or any other country or any political subdivision thereof asserts a claim that Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed or for any other reason other than the gross negligence or wilful misconduct of Agent), such Lender shall indemnify Agent fully for all amounts paid, directly or indirectly, by Agent as tax, withholding therefore, or otherwise, including penalties, interest and additions to tax, and including taxes imposed by any jurisdiction on amounts payable to Agent under this paragraph, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for Agent, which attorneys may be employees of Agent). The obligations of the Lenders under this paragraph shall survive the payment of the Obligations and termination of this Agreement.

(m) If Agent or any Lender determines in its sole, good faith reasonable judgment that it has received a remission for, or a refund or direct credit in respect of and specifically associated with any Taxes or Other Taxes as to which it has been indemnified by any Credit Party, or with respect to which such Credit Party has paid additional amounts, it shall promptly notify the Credit Party of such remission, refund or direct credit and shall within 30 days from the date of receipt of such refund or benefit of such remission or direct credit pay over the amount of such refund or benefit of such remission or direct credit (including any interest paid or credited by the relevant Governmental Authority attributable to such remission, refund or direct credit) to the Credit Party but only to the extent of indemnity payments made, or additional amounts paid, by such Credit Party with respect to the Taxes or Other Taxes giving rise to such remission, refund or direct credit, net of all out-of-pocket expenses of such Person.

Notwithstanding any other provision of this Agreement, if Agent or any Lender has made a payment to any Credit Party in respect of a remission, refund or direct credit of Taxes or Other Taxes pursuant to the preceding sentence, to the extent any remission is withdrawn or any refund or direct credit is required to be repaid to the relevant taxing authority, such amount shall be treated as a Tax subject to indemnification under this Section 13.1.

(n) If, at any time, Borrower requests any Lender to deliver any forms or other documentation in addition to those forms required to be delivered by such Lender pursuant to Section 13.1, then Borrower shall, on demand of such Lender through Agent, reimburse such Lender for any costs and expenses (including attorneys’ fees and expenses) reasonably incurred by such Lender in the preparation or delivery of such forms or other documentation.

(o) If Borrower is required to pay additional amounts to any Lender or Agent pursuant to Section 13.1, then such Lender shall use its reasonable efforts (consistent with legal and regulatory restrictions) to change the jurisdiction of its Lending Office so as to eliminate any such additional payment by Borrower which may thereafter accrue if such change in the judgment of such Lender is not otherwise disadvantageous to such Lender. In addition to the foregoing and if such Lender deems it commercially reasonable in its sole discretion, such Lender agrees to obtain a refund or credit for any additional amounts paid by Borrower to such Lender or Agent pursuant to Sections 13.1, and, to the extent any such refund or credit is obtained, apply such amounts to the outstanding Obligations owing by such Credit Party under this Agreement.

The agreements and obligations of the Credit Parties in this Article XIII shall survive the payment of all other Obligations.

XIV. GUARANTEE AND INDEMNITY

14.1 Guarantee and indemnity

Each UK Guarantor irrevocably and unconditionally jointly and severally:

(a) guarantees to each Lender Party punctual performance by each Borrower of all that Borrower’s obligations under the Loan Documents;

(b) undertakes with each Lender Party that whenever a Borrower does not pay any amount when due under or in connection with any Loan Document, that UK Guarantor shall immediately on demand pay that amount as if it was the principal obligor; and

(c) indemnifies each Lender Party immediately on demand against any cost, loss or liability suffered by that Lender Party if any obligation guaranteed by it is or becomes unenforceable, invalid or illegal. The amount of the cost, loss or liability shall be equal to the amount which that Lender Party would otherwise have been entitled to recover.

14.2 Continuing guarantee

This guarantee is a continuing guarantee and will extend to the ultimate balance of sums payable by any Credit Party under the Loan Documents, regardless of any intermediate payment or discharge in whole or in part.

14.3 Reinstatement

If any payment by a Credit Party or any discharge given by a Lender Party (whether in respect of the obligations of any Credit Party or any security for those obligations or otherwise) is avoided or reduced as a result of insolvency or any similar event:

(a) the liability of each Credit Party shall continue as if the payment, discharge, avoidance or reduction had not occurred; and

(b) each Lender Party shall be entitled to recover the value or amount of that security or payment from each Credit Party, as if the payment, discharge, avoidance or reduction had not occurred.

14.4 Waiver of defenses

The obligations of each UK Guarantor under this clause 14 will not be affected by an act, omission, matter or thing which, but for this clause 14, would reduce, release or prejudice any of its obligations under this clause 14 (without limitation and whether or not known to it or any Lender Party) including:

(a) any time, waiver or consent granted to, or composition with, any Credit Party or other person;

(b) the release of any other Credit Party or any other person under the terms of any composition or arrangement with any creditor of any Credit Party;

(c) the taking, variation, compromise, exchange, renewal or release of, or refusal or neglect to perfect, take up or enforce, any rights against, or security over assets of, any Credit Party or other person or any non-presentation or non-observance of any formality or other requirement in respect of any instrument or any failure to realize the full value of any security;

(d) any incapacity or lack of power, authority or legal personality of or dissolution or change in the members or status of an Credit Party or any other person;

(e) any amendment (however fundamental) or replacement of a Loan Document or any other document or security;

(f) any unenforceability, illegality or invalidity of any obligation of any person under any Loan Document or any other document or security; or

(g) any insolvency or similar proceedings.

14.5 Immediate recourse

Each UK Guarantor waives any right it may have of first requiring any Lender Party (or any trustee or agent on its behalf) to proceed against or enforce any other rights or security or claim payment from any person before claiming from that UK Guarantor under this Article 14. This waiver applies irrespective of any law or any provision of a Loan Document to the contrary.

14.6 Appropriations

Until all amounts which may be or become payable by the Credit Parties under or in connection with the Loan Documents have been irrevocably paid in full, each Lender Party (or any trustee or agent on its behalf) may:

(a) refrain from applying or enforcing any other monies, security or rights held or received by that Lender Party (or any trustee or agent on its behalf) in respect of those amounts, or apply and enforce the same in such manner and order as it sees fit (whether against those amounts or otherwise) and no Guarantor shall be entitled to the benefit of the same; and

(b) hold in an interest-bearing suspense account any monies received from any Guarantor or on account of any Guarantor’s liability under this clause 14.

14.7 Deferral of Guarantors’ rights

Until all amounts which may be or become payable by the Obligors under or in connection with the Loan Documents have been irrevocably paid in full and unless the Agent otherwise directs, no UK Guarantor will exercise any rights which it may have by reason of performance by it of its obligations under the Loan Documents:

(a) to be indemnified by an Credit Party;

(b) to claim any contribution from any other guarantor of any Credit Party’s obligations under the Loan Documents; and/or

(c) to take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights of the Lender Parties under the Loan Documents or of any other guarantee or security taken pursuant to, or in connection with, the Loan Documents by any Lender Party.

14.8 Release of UK Guarantors’ right of contribution

If any UK Guarantor (a “Retiring Guarantor”) ceases to be a UK Guarantor in accordance with the terms of the Loan Documents for the purpose of any sale or other disposal

of that Retiring UK Guarantor then on the date such Retiring UK Guarantor ceases to be a UK Guarantor:

(a) that Retiring UK Guarantor is released by each other UK Guarantor from any liability (whether past, present or future and whether actual or contingent) to make a contribution to any other UK Guarantor arising by reason of the performance by any other UK Guarantor of its obligations under the Loan Documents; and

(b) each other UK Guarantor waives any rights it may have by reason of the performance of its obligations under the Loan Documents to take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights of the Lender Parties under any Loan Document or of any other security taken pursuant to, or in connection with, any Loan Document where such rights or security are granted by or in relation to the assets of the Retiring UK Guarantor.

14.9 Additional security

This guarantee is in addition to and is not in any way prejudiced by any other guarantee or security now or subsequently held by any Lender Party.

14.10 Guarantee limitations

This guarantee does not apply to any liability to the extent that it would result in this guarantee constituting unlawful financial assistance within the meaning of sections 151 and 152 of the Act or any equivalent and applicable provisions under the laws of the jurisdiction of incorporation of the relevant Guarantor.

IN WITNESS WHEREOF, each of the parties has duly executed this Revolving Facility Agreement as of the date first written above.

Appendix B

Letters of Credit

(a) Subject to the terms and conditions of this Agreement, Agent agrees to cause the L/C Issuer from time to time during the Term to issue standby letters of credit or documentary letters of credit for the account of Borrower (each standby letter of credit or documentary letter of credit, as applicable, a “Letter of Credit”) or to purchase participations or execute indemnities or reimbursement obligations (each such undertaking, an “L/C Undertaking”) with respect to documentary letters of credit which comply with the provisions of this Appendix B issued by an Underlying Issuer for the account of Borrower (each Letter of Credit or L/C Undertaking, as the context requires, constituting or relating to a documentary letter of credit is referred to in this Agreement as a “Documentary Letter of Credit” and each Letter of Credit or L/C Undertaking, as the context requires, constituting or relating to a standby letter of credit is referred to in this Agreement as a “Standby Letter of Credit”); provided, however, that the L/C Issuer will not be required to issue, purchase or execute a requested Documentary Letter of Credit or a requested Standby Letter of Credit if any of the following would result after giving effect thereto: (i) the Letter of Credit Usage would exceed the Facility Cap minus the amount of Advances then outstanding or (ii) the aggregate face amount of all Standby Letters of Credit and Documentary Letters of Credit then outstanding would exceed $500,000. If L/C Issuer is obligated to advance funds under a Documentary Letter of Credit or Standby Letter of Credit, Borrower immediately shall reimburse such L/C Disbursement to L/C Issuer by paying to Agent an amount equal to such L/C Disbursement not later than 1:00 p.m. (New York City time) on the date that such L/C Disbursement is made, if Borrower shall have received written or telephonic notice of such L/C Disbursement prior to 12:00 p.m. (New York City time) on such date, or, if such notice has not been received by Borrower prior to such time on such date, then not later than 1:00 p.m. (New York City time), on the first Business Day that Borrower has such notice prior to 12:00 p.m. (New York City time), and, in the absence of such reimbursement, the L/C Disbursement immediately and automatically shall be deemed to be an Advance hereunder and, thereafter, shall bear interest at the Applicable Rate for Advances. To the extent an L/C Disbursement is deemed to be an Advance hereunder, Borrower’s obligation to reimburse such L/C Disbursement shall be discharged and replaced by the resulting Advance. The portion of the face amount of the Documentary Letters of Credit and Standby Letters of Credit that has not been drawn upon shall not bear interest.

(b) Borrower may from time to time upon notice not later than (i) 12:00 noon (New York City time), at least one (1) Business Day in advance, request Agent and L/C Issuer to assist Borrower in establishing or opening a Standby Letter of Credit by delivering to L/C Issuer with a copy to Agent, at the Payment Office, the L/C Issuer’s standard form of standby letter of credit application (with such changes thereto as Borrower, Agent and L/C Issuer may agree) (the “Standby Letter of Credit Application”) completed to the satisfaction of Agent and the L/C Issuer (each in the exercise of its Permitted Discretion), and such other certificates, documents and other papers and information as Agent or L/C Issuer may reasonably request, and (ii) 12:00 noon (New York City time) at least one (1) Business Day in advance, request Agent and L/C Issuer to assist Borrower in establishing a Documentary Letter of Credit by delivering to L/C Issuer, with a copy to Agent, at the Payment Office, the L/C Issuer’s standard form of documentary letter of credit application (each “Documentary Letter of Credit Application”)

completed to the satisfaction of the Agent and L/C Issuer (in the exercise of its Permitted Discretion), and such other certificates, documents and other papers and information as Agent or L/C Issuer may reasonably request. If requested by Agent or L/C Issuer, Borrower also shall be an applicant under the application with respect to any Underlying Letter of Credit that is to be the subject of an L/C Undertaking. Borrower acknowledges that, unless L/C Issuer otherwise agree, the issuance of any Letter of Credit shall occur no sooner than three (3) Business Days following the submission of a Standby Letter of Credit Application or Documentary Letter of Credit Application, as the case may be, to, and to the satisfaction of Agent and the L/C Issuer (each in the exercise of its Permitted Discretion).

(c) Each Documentary Letter of Credit and each Standby Letter of Credit (and, in each case, each corresponding Underlying Letter of Credit) shall, among other things, (i) be in form and substance acceptable to the L/C Issuer (in the exercise of its Permitted Discretion), including the requirement that the amounts payable thereunder must be payable in Dollars, (ii) provide for the payment of sight or time drafts when presented for honour thereunder in accordance with the terms thereof and when accompanied by the documents described therein, (iii) in the case of a Documentary Letter of Credit, have an expiry date not later than one hundred and eighty (180) days after such Documentary Letter of Credit’s date of issuance and in no event later than 30 days prior to the last day of the Term, and (iv) in the case of a Standby Letter of Credit, have an expiry date not later than twelve (12) months after such Standby Letter of Credit’s date of issuance and in no event later than 30 days prior to the last day of the Term. Each Standby Letter of Credit Application and each Standby Letter of Credit shall be subject to the International Standby Practices (ISP98) issued by the Institute for International Banking Law and Practice, Inc., and any amendments or revision thereof.

(d) In connection with the issuance of any Letter of Credit, Borrower shall indemnify, save and hold Agent, each Lender and each L/C Issuer harmless from any loss, cost, expense or liability, including, without limitation, payments made by Agent, any Lender or any L/C Issuer, and reasonable out-of-pocket expenses and reasonable attorneys’ fees incurred by Agent, any Lender or any L/C Issuer arising out of, or in connection with, any Letter of Credit to be issued for the account of Borrower, except for any such losses, costs, expenses or liabilities arising out of Agent’s, such Lender’s or such L/C Issuer’s gross negligence or willful misconduct. Borrower shall be bound by the L/C Issuer’s regulations and reasonable good faith interpretations of any Letter of Credit issued or created for Borrower’s account, although this interpretation may be different from Borrower’s own. Neither Agent nor any Lender, any L/C Issuer, nor any of its correspondents shall be liable for any error, negligence, or mistakes, whether of omission or commission, in following Borrower’s instructions or those contained in any Letter of Credit or of any modifications, amendments or supplements thereto or in issuing or paying any Letter of Credit, except for, and solely to the extent of, Agent’s, any Lender’s, such L/C Issuer’s or such correspondents’ gross negligence or wilful misconduct.

(e) Borrower shall authorize and direct each Underlying Issuer to name Borrower as the “Account Party” therein and to accept and rely upon the L/C Issuer’s instructions and agreements with respect to all matters arising in connection with the documentary letters of credit issued by it and the applications therefor.

(f) In connection with all Documentary Letters of Credit issued or caused to be issued by the L/C Issuer under this Agreement, Borrower hereby appoints Agent, L/C Issuer and each Underlying Issuer, or the respective designee(s) of any of them, as its attorney, with full power and authority, after the occurrence and during the continuance of an Event of Default, and in each case with respect to the Property shipped under such Documentary Letter of Credit, and any documents, instruments or agreements under or in connection with such Documentary Letter of Credit for such Property (i) to sign and/or endorse Borrower’s name upon any warehouse or other receipts or any letter of credit applications; (ii) to sign Borrower’s name on bills of lading; (iii) to clear Inventory through the United States of America Customs Department (“Customs”) in the name of Borrower, L/C Issuer, Underlying Issuer, Agent or Agent’s, L/C Issuer’s or Underlying Issuer’s designee, and to sign and deliver to Customs officials powers of attorney in the name of Borrower for such purpose; (iv) to complete in the name of Agent, L/C Issuer, Underlying Issuer or Agent’s, L/C Issuer’s or Underlying Issuer’s designee, any order, sale or transaction, obtain the necessary documents in connection therewith, and collect the proceeds thereof; (v) to clear and resolve any questions of non-compliance of documents; (vi) to give any instructions as to acceptance or rejection of any documents or goods; (vii) to execute any and all applications for steamship or airways guarantees, indemnities or delivery orders; (viii) to grant any extensions of the maturity of, time of payment for, or time of presentation of, any drafts, acceptances, or documents; and (ix) to agree to any amendments, renewals, extensions, modifications, changes or cancellation of any of the terms or conditions of any of the applications, Documentary Letters of Credit, drafts or acceptances; all in Agent’s, L/C Issuer’s or Underlying Issuer’s sole name, and the L/C Issuer shall be entitled to comply with and honour any and all such documents or instruments executed by or received solely from Agent, all without notice to or consent from Borrower. Agent, L/C Issuer, Underlying Issuer and their agents or attorneys will not be liable for any acts or omissions or for any error of judgment or mistakes of fact or law, except gross negligence or wilful misconduct. This power, being coupled with an interest, may only be exercised by Agent or L/C Issuer if an Event of Default has occurred and is continuing and is irrevocable as long as any Documentary Letters of Credit remain outstanding. Borrower hereby authorizes and directs any Underlying Issuer to deliver to the L/C Issuer all instruments, documents, and such other writings and property received by such Underlying Issuer pursuant to such Underlying Letters of Credit and to accept and rely upon the L/C Issuer’s instructions with respect to all matters arising in connection with such Underlying Letter of Credit and the related application.

(g) Except as expressly provided for herein, neither Agent, L/C Issuer, any Lender nor any Underlying Issuer shall be responsible for: the existence, character, quality, quantity, condition, packing, value or delivery of the goods purporting to be represented by any documents; any differences or variation in the character, quality, quantity, condition, packing, value or delivery of the goods from that expressed in the documents; the validity, sufficiency or genuineness of any documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent, or forged; the time, place, manner or order in which shipment is made; partial or incomplete shipment, or failure or omission to ship any or all of the goods referred to in the Documentary Letters of Credit or documents; any deviation from instructions, delay, default, or fraud by the shipper and/or any one else in connection with the Collateral or the shipping thereof; or any breach of contract between the shipper or vendors and Borrower.

(h) Borrower must ensure that any necessary import, export or other licenses or certificates for the import or handling of the Collateral shipped under a Documentary Letter of Credit will have been promptly procured; all foreign and domestic governmental laws and regulations in regard to the shipment and importation of such Collateral or the financing thereof will have been promptly and fully complied with in all material respects; and any certificates in that regard that Agent and/or L/C Issuer may at any time request will be promptly furnished. Borrower warrants and represents that all shipments made under any such Documentary Letters of Credit are in accordance in all material respects with the governmental laws and regulations of the countries in which the shipments originate and terminate, and are not prohibited by any such law and regulations. Borrower assumes all risk, liability and responsibility for, and agrees to pay and discharge all present and future local, state, federal or foreign taxes, duties, or levies in respect of such Collateral and/or the applicable Documentary Letter of Credit. Any embargo, restriction, laws, customs or regulations of any country, state, city or other political subdivision where such Collateral is or may be located or wherein payments are to be made or wherein drafts may be drawn, negotiated, accepted, or paid shall be solely at Borrower’s risk, liability and responsibility.

(i) Each Lender shall, to the extent of its Pro Rata Share of the aggregate amount of all disbursements made with respect to the Letters of Credit, be deemed to have irrevocably purchased an undivided participation in each L/C Disbursement and each Advance made as a consequence of such disbursement. If at the time a L/C Disbursement is made the unpaid balance of Advances exceeds or would exceed, with the making of such L/C Disbursement, the Facility Cap and if such L/C Disbursement is not reimbursed by Borrower within one (1) Business Day, then Agent shall promptly notify each Lender, and upon Agent’s demand each Lender shall pay to Agent such Lender’s Pro Rata Share of such unreimbursed disbursement together with such Lender’s Pro Rata Share of Agent’s unreimbursed costs and expenses relating to such unreimbursed disbursement. Upon receipt by Agent of a repayment from Borrower of any amount disbursed by Agent for which Agent had already been reimbursed by the Lenders, Agent shall deliver to each of the Lenders that Lender’s Pro Rata Share of such repayment. Each Lender’s participation commitment shall continue until the last to occur of any of the following events: (i) L/C Issuer ceases to be obligated to issue or to cause the issuance of Letters of Credit hereunder; (ii) no Letter of Credit remains outstanding and uncancelled; or (iii) all Persons (other than Borrower) have been fully reimbursed for all payments made under or relating to all Letters of Credit.

(j) The obligations of a Lender to make payments to Agent for the account of Agent or the L/C Issuer with respect to a Letter of Credit shall be irrevocable, without any qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including, without limitation, any of the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any of the Loan Documents;

(ii) the existence of any claim, setoff, defense or other right that Borrower may have at any time against a beneficiary named in such Letter of Credit or any transferee of such Letter of Credit (or any Person for which any such transferee may

be acting), Agent, L/C Issuer, any Lender, or any other person, whether in connection with this Agreement, such Letter of Credit, the transactions contemplated herein or any related transactions (including any underlying transactions between Borrower or any other party and the beneficiary named in such Letter of Credit);

(iii) any draft, certificate or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(iv) the surrender or impairment of any security for the performance or observance of any of the terms of this Agreement or any of the Loan Documents;

(v) any failure by Agent or the L/C Issuer to provide any notices required pursuant to this Agreement relating to such Letter of Credit;

(vi) any payment by the L/C Issuer under any of the Letters of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit (if, in the good faith opinion of the L/C Issuer, such prepayment is deemed to be appropriate); or

(vii) the occurrence and continuation of any Default or Event of Default;

provided, however, that after paying in full its reimbursement obligation hereunder, nothing herein shall adversely affect the right of Borrower or any Lender, as the case may be, to commence any proceeding against such L/C Issuer for any wrongful disbursement made by such L/C Issuer under a Letter of Credit as a result or solely to the extent of acts or omissions constituting gross negligence or wilful misconduct on the part of such L/C Issuer;

(k) If by reason of (i) any change in any applicable law, treaty, rule, or regulation or any change in the interpretation or application thereof by any Governmental Authority, or (ii) compliance by any Underlying Issuer or Lender with any direction, request, or requirement (irrespective of whether having the force of law) of any Governmental Authority or monetary authority including, Regulation D of the Federal Reserve Board as from time to time in effect (and any successor thereto):

(1) any reserve, deposit, or similar requirement is or shall be imposed or modified in respect of any Letter of Credit issued hereunder, or

(2) there shall be imposed on any Underlying Issuer, Lender or Agent any other condition regarding any Letter of Credit issued pursuant hereto;

and the result of the foregoing is to increase, directly or indirectly, the cost to any Underlying Issuer, Lender or Agent of issuing, making, guaranteeing, or maintaining any Letter of Credit or to reduce the amount receivable in respect thereof by any Underlying Issuer, Lender or Agent, then, and in any such case, Agent may, at any time within a reasonable period after the additional cost is incurred or the amount received is reduced, notify Borrower, and Borrower shall pay on demand such amounts as necessary to compensate Agent and Lenders for such additional cost or

reduced receipt, together with interest on such amount from the date of such demand until payment in full thereof at the Applicable Rate for Advances. The determination by Agent of any amount due pursuant to this Section (k), as set forth in a certificate setting forth the calculation thereof in reasonable detail, shall, in the absence of manifest or demonstrable error, be final and conclusive and binding on all of the parties hereto.

(l) Borrower acknowledges and agrees that certain of the Documentary Letters of Credit may provide for the presentation of time drafts to the Underlying Issuer. If an Underlying Issuer accepts such a time draft that is presented under and in accordance with an Underlying Letter of Credit, it is acknowledged and agreed that (i) the Documentary Letter of Credit will require the L/C Issuer to reimburse the Underlying Issuer for amounts paid on account of such time draft on or after the maturity date thereof, (ii) the pricing provisions hereof (including Section 3.3) shall continue to apply, until payment of such time draft on or after the maturity date thereof, as if the Underlying Letter of Credit were still outstanding, and (iii) on the date on which L/C Issuer makes payment to the Underlying Issuer of the amounts paid on account of such time draft, Borrower promptly shall reimburse such amount to L/C Issuer as provided in Section (a) above and such amount shall constitute an L/C Disbursement hereunder.

If any portion of the Letter of Credit Usage, whether or not then due and payable, remains unpaid or outstanding on the Revolving Loan Maturity Date or such earlier date as this Agreement may be terminated, Borrower shall: (A) provide cash collateral therefor in the manner described in Section 3.3; or (B) cause all such Letters of Credit and guaranties thereof, if any, to be cancelled and returned; or (C) deliver a stand-by letter (or letters) of credit in guarantee of such portion of the Letter of Credit Usage, which stand-by letter (or letters) of credit shall be of like tenor and duration (plus thirty (30) additional days) as, and in an amount equal to at least 105% of the aggregate maximum amount then available to be drawn under, such Letters of Credit to which such outstanding Letter of Credit Usage relate and shall be issued by a Person, and shall be subject to such terms and conditions, as are satisfactory to Agent in its Permitted Discretion.
