WHEREAS, all capitalized terms herein shall have the meanings ascribed thereto in Annex A hereto which is incorporated herein by reference.

NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, Borrower, Lender and Investment Manager agree as follows:

ARTICLE 1

AMOUNTS AND TERMS OF LOANS

1.1 Loans. Subject to the terms and conditions of this Agreement and in reliance upon the representations and warranties of Borrower contained herein:

(a) Initial Bridge Loan. Borrower shall issue and sell to Lender on the Initial Closing Date (as defined below), and Lender shall purchase for face value on the Initial Closing Date (the “Initial Closing”) a senior secured promissory note containing the terms and conditions set forth herein and in the form of note attached hereto as Exhibit 1.1(a), payable to the order of Lender in the principal amount of Ten Million Dollars

($10,000,000) (the “Initial Bridge Note”), subject to the satisfaction of the conditions to closing set forth in Section 2.1 of this Agreement. The date on which the Initial Closing shall take place is referred to herein as the “Initial Closing Date.”

(b) Subsequent Bridge Loan and Term Loan. Within 90 days (or such longer period as is agreed to between VCI and the Investment Manager) following the Initial Closing Date (the “Subsequent Closing”), so long as (i) the Initial Bridge Note is outstanding, (ii) no Default or Event of Default has occurred and is continuing or would result from the consummation of the Subsequent Closing and the use of proceeds therefrom, and (iii) all of the conditions set forth in Section 2.2 have been satisfied, if Borrower so elects, Borrower shall issue and sell to Lender, and Lender shall purchase for face value: (1) a senior secured promissory note containing the terms and conditions set forth herein and in the form of note attached hereto as Exhibit 1.1(a), payable to the order of Lender in the principal amount of Five Million Dollars ($5,000,000) (or such other amount, when combined with the principal amount of the Initial Bridge Note, equals $15,000,000) (the “Subsequent Bridge Note” and together with the Initial Bridge Note, the “Bridge Notes”)) and (2) a senior secured promissory note containing the terms and conditions set forth herein and in the form of note attached hereto as Exhibit 1.1(b), payable to the order of Lender in the principal amount of Fifteen Million Dollars ($15,000,000) (the “Term Note” and collectively with the Initial Bridge Note and the Subsequent Bridge Note, the “Notes” and each such Note, a “Note”). The date on which the Subsequent Closing takes place is hereinafter referred to as the “Subsequent Closing Date”.

1.2 Warrants. At the Initial Closing, VCI shall issue and sell to Lender, as part of its inducement to purchase the Notes, (i) a warrant (the “Initial Warrant”) entitling Lender to purchase 4,500,000 shares of VCI’s common stock, par value $0,01 per share (“Common Stock”) at an exercise price equal to $0.01 per share on the basis set forth therein, which Initial Warrant shall be in the form attached hereto as Exhibit 1.2(a), and (ii) a warrant (the “Additional Warrant, and together with the Initial Warrant, the “Warrants”), entitling Lender to purchase 500,000 shares of Common Stock at an exercise price equal to $0.01 per share on the basis set forth therein, which Additional Warrant shall be in the form attached hereto as Exhibit 1.2(b). Lender shall have registration rights with respect to the shares of Common Stock issuable upon exercise of the Warrants on substantial parity with those of the holders of warrants issued in connection with VCI’s Series E Convertible Preferred Stock offering on or around the date hereof, as further described in the Warrants. In addition, Borrower and Lender, as a result of arm’s length bargaining, agree that:

(a) Neither Lender, Investment Manager nor any affiliated company of Lender or Investment Manager has rendered any services to Borrower in connection with this Agreement;

(b) The Warrants are not being issued as compensation;

(c) The aggregate fair market value of the Initial Warrant, if issued apart from the Notes, is $1,845,000, and the aggregate fair market value of the Additional Warrant, if issued apart from the Notes is $205,000; and

(d) All tax returns and other information return of each party relative to this Agreement and the Notes and Warrants issued pursuant hereto shall consistently reflect the matters agreed to in (a) through (c) above.

1.3 Notes.

(a) Security. The Notes and the Obligations of Borrower shall be secured in accordance with the terms of the Collateral Documents.

(b) Maturity. The principal amount of the Term Note issued under this Agreement, any accrued and unpaid interest thereon, the applicable Payment Premium (as defined below) and all other amounts then owing by Borrower to Lender or Investment Manager hereunder in connection with the Term Note shall be due and payable on the date that is thirty six (36) months from the Subsequent Closing Date (the “Term Loan Maturity Date”), unless such amounts become due and payable earlier in accordance with the terms hereof or otherwise. The principal amount of the Bridge Notes issued under this Agreement, any accrued and unpaid interest thereon and all other amounts then owing by Borrower to Lender or Investment Manager hereunder in connection with the Bridge Notes shall be due and payable on July 1, 2007 (the “Bridge Loan Maturity Date” and together with the Term Loan Maturity Date, the “Maturity Dates”), unless such amounts become due and payable earlier in accordance with the terms hereof or otherwise.

(c) Interest. The outstanding principal amount of each Bridge Note shall bear interest at a rate per annum equal to fourteen percent (14%) (the “Bridge Rate”), which accrued interest shall be payable by Borrower to Investment Manager, for the benefit of Lender, in cash in arrears on each Quarterly Interest Payment Date, or upon a Liquidity Event or Partial Liquidity Event, on the date of any prepayment or at such time such amount becomes otherwise due and payable in accordance with the terms hereof. The outstanding principal amount of the Term Note shall bear interest at a rate per annum equal to the Applicable Federal Rate (the “Term Rate”). A portion of the interest accruing at the Term Rate equal to one-half of one percent (0.5%) of the outstanding principal amount of the Term Note shall be payable in cash in arrears on each Quarterly Interest Payment Date. The remaining accrued and unpaid interest on the Term Note shall be payable by Borrower to Investment Manager, for the benefit of Lender, on the Term Loan Maturity Date, upon a Liquidity Event or Partial Liquidity Event, on the date of any prepayment or at such time such amount becomes due and payable in accordance with the terms hereof. All computations of interest payable hereunder (i.e., on both Bridge Notes and the Term Note) shall be on the basis of a 360-day year consisting of twelve 30-day months and actual days elapsed in the period of which such interest is payable.

(d) Default Interest on Bridge Notes. Upon the occurrence and during the continuance of any Event of Default under any Bridge Note, the outstanding principal

amount on each such Bridge Note then due and payable and all other amounts otherwise due and payable hereunder (including accrued and unpaid interest at the Bridge Rate) shall bear additional interest on each day until paid at a rate per annum equal to two percent (2%).

1.4 Payment Premium on Term Note; Default Interest on Term Note. Upon any payment or prepayment of any principal amount of the Term Note by the Borrower, whether on the Maturity Date or upon the occurrence of a Liquidity Event, Partial Liquidity Event, voluntary prepayment or acceleration, Borrower shall pay to Investment Manager, for the benefit of Lender, a payment premium (the “Payment Premium”) equal to the amount required to provide the Lender with an IRR with respect to the principal amount of the Term Note being repaid of thirteen and one-half of one percent (13.5%); provided that during any period in which an Event of Default under the Term Note shall have occurred and be continuing, the IRR for such period shall be automatically adjusted to equal fifteen and one-half of one percent (15.5%), all in accordance with the calculation examples set forth on Exhibit 1.4. Notwithstanding anything to the contrary contained herein, in the event of a prepayment made pursuant to Section 1.8, the Payment Premium shall be calculated assuming the payment of all outstanding principal and accrued and unpaid interest, whether or not such amounts are actually paid in connection with the subject prepayment.

1.5 Facility Fees.

(a) The parties hereto acknowledge that Borrower has paid to Investment Manager, for the benefit of Lender, an amount equal to $150,000 (the “Bridge Fee”).

(b) At the Subsequent Closing, Borrower shall pay to Investment Manager, for the benefit of Lender, an amount equal to two percent (2%) of the principal amount of the Term Note issued at the Subsequent Closing (the “Term Fee,” and collectively with the Bridge Fee, the “Facility Fees”).

1.6 Expenses and Attorneys Fees. Borrower agrees to pay or reimburse Investment Manager and Lender for: (a) all costs, expenses and other charges in respect of any lien, tax and judgment searches performed by a service firm, to be chosen by Investment Manager in its sole discretion, in connection with the transactions contemplated by the Loan Documents and other collateral searches and filings; (b) all reasonable out-of-pocket costs and expenses of Investment Manager and Lender including the legal fees and disbursements of ▇▇▇▇▇▇ Godward Kronish LLP, incurred in connection with the negotiation, preparation, execution and delivery of this Agreement and the other Loan Documents and the other instruments and agreements entered into pursuant hereto and thereto; provided, that any legal fees of Investment Manager and Lender in excess of $70,000 and any out-of-pocket expenses of Investment Manager and Lender in excess of $10,000 shall be subject to approval by Borrower prior to reimbursement; (c) all reasonable out-of-pocket costs and expenses of Investment Manager and Lender including the fees and disbursements of counsel for Investment Manager and Lender, incurred in connection with the negotiation, preparation, execution and delivery of any modification, supplement or waiver of this Agreement and any

other Loan Documents (whether or not consummated); (d) all expenses of Investment Manager and Lender including the fees and disbursements of counsel for Investment Manager and Lender in connection with (1) any Default or Event of Default and any enforcement or collection proceedings resulting therefrom, including, without limitation, all manner of participation in or other involvement with (A) bankruptcy, insolvency, receivership, foreclosure, winding up or liquidation proceedings, (B) judicial or regulatory proceedings and (C) workout, restructuring or other negotiations or proceedings (whether or not the workout, restructuring or transaction contemplated thereby is consummated) and (2) the enforcement of this Section 1.6; and (e) all transfer, stamp, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document referred to herein or therein and all costs, expenses, taxes, assessments and other charges incurred in connection with any filing, registration, recording or perfection of any security interest contemplated by the Collateral Documents or any other document referred to therein. Payments under this Section shall be made promptly and in any case no later than ten (10) days after written demand therefor. Upon the Initial Closing, the non-refundable advance from Borrower to Investment Manager in the amount of $40,000 shall be credited to the reimbursement of any expenses of Investment Manager and Lender incurred as of the Initial Closing and entitled to reimbursement hereunder. The remaining amount, if any, of the non-refundable advance from Borrower shall be credited to the reimbursement of any expenses of Investment Manager and Lender incurred as of the Subsequent Closing and entitled to reimbursement hereunder and to the Term Fee payable under Section 1.5(b) above. Any payments under this Section 1.6 which remain outstanding more than sixty (60) days after written demand therefor shall accrue interest at a per annum rate equal to (x) the “prime rate” as set forth in the Wall Street Journal on the date of determination, plus (y) two percent (2.00%).

1.7 Payments. All payments by Borrower of the Obligations shall be without deduction, defense, setoff or counterclaim and shall be made in same day funds and delivered to Lender, for the benefit of Investment Manager and Lender, as applicable, by wire transfer to the account of Lender specified on the signature page hereof or such other place as Investment Manager may from time to time designate in writing. Borrower shall receive credit on the day of receipt for funds received by Investment Manager by 2:00 p.m. (Eastern Time). Funds received after 2:00 pm (Eastern Time) shall be deemed to have been paid on the next Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the payment may be made on the next succeeding Business Day and such extension of time shall be included in the computation of the amount of interest and Fees due hereunder.

1.8 Prepayments.

(a) Voluntary Prepayments. At any time and from time to time, Borrower may prepay the amounts due under the Notes, in whole or in part. Any prepayment shall include all costs and fees incurred as of the date of payment, all accrued and unpaid interest, the principal amount intended to be prepaid, and any applicable Payment Premium. Prepayments shall be applied in accordance with Section 1.9 or as otherwise may be agreed by Lender. If Borrower elects to prepay all or any part of the principal due under the Notes

pursuant to this Section 1.8(a), Borrower shall give notice of such prepayment to the Investment Manager to be prepaid not less than ten (10) days or more than sixty (60) days prior to the date fixed for prepayment, specifying the amounts to be repaid as required by this Section 1.8(a).

(b) Mandatory Prepayment.

(i) Liquidity Event. Upon the occurrence of a Liquidity Event, Borrower shall immediately pay to Investment Manager, for the benefit of Lender, all amounts due under the Loans as set forth in this Agreement, including, without limitation, all costs and fees incurred as of the date of payment, all accrued and unpaid interest, the principal outstanding as of the date of such payment, and the applicable Payment Premium. The payments made pursuant to this Section 1.8(b)(i) shall be applied in accordance with Section 1.9.

(ii) Partial Liquidity Event. Upon the occurrence of a Partial Liquidity Event, Borrower shall immediately pay to the Investment Manager, for the benefit of Lender, in respect of the Loans an amount equal to (A) the net cash proceeds received by Borrower in the Partial Liquidity Event minus (B) Thirty Million Dollars ($30,000,000), but not in excess of all amounts due under the Loans as set forth in this Agreement, including, without limitation, all costs and fees incurred as of the date of payment, all accrued and unpaid interest, the principal outstanding as of the date of such payment, and the applicable Payment Premium. The payments made pursuant to this Section 1.8(b)(ii) shall be applied in accordance with Section 1.9.

1.9 Application of Payments. With respect to any payment hereunder, including without limitation the prepayments described in Sections 1.8(a) and 1.8(b), such payments shall be applied first to reduce the Obligations under the Bridge Notes and then to reduce the Obligations under the Term Note, in each case in the following order: (a) with respect to the Bridge Notes: first, to the payment of all fees and expenses due and payable pursuant to this Agreement as apportioned to the principal amount of the Bridge Notes (compared to the principal amount of all Notes); second, to accrued and unpaid interest due on the Bridge Notes; third, to reduce the outstanding principal balance under the Bridge Notes; and fourth, to any other Obligations of Borrower owing to Investment Manager or Lender with respect to the Bridge Notes hereunder; and (b) with respect to the Term Note: first, to the applicable Payment Premium; second, to the payment of all fees and expenses due and payable pursuant to this Agreement as apportioned to the principal amount of the Term Note (compared to the principal amount of all Notes); third, to reduce the outstanding principal balance under the Term Note; and fourth, to any other Obligations of Borrower owing to Investment Manager or Lender with respect to the Term Note hereunder; provided that notwithstanding any prior allocation of payments to the Payment Premium, upon the final payment in full of all outstanding principal under the Term Note, the Payment Premium shall be recalculated and any additional Payment Premium shall be immediately due and payable.

1.10 Maximum Lawful Rate. Notwithstanding anything to the contrary contained herein, if a court of competent jurisdiction determines in a final order that the effective Bridge

Rate payable hereunder exceeds the highest rate of interest permissible under law (the “Maximum Lawful Rate”), then so long as the Maximum Lawful Rate would be so exceeded, the effective Bridge Rate payable hereunder shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the effective Bridge Rate payable hereunder is less than the Maximum Lawful Rate, Borrower shall continue to pay interest hereunder at the Maximum Lawful Rate until such time as the total interest received by Investment Manager, on behalf of Lender, is equal to the total interest that would have been received had the effective Bridge Rate payable hereunder been (but for the operation of this paragraph) the interest rate payable since the respective date of issuance of the subject Bridge Note as otherwise provided in this Agreement. Thereafter, the effective Bridge Rate payable hereunder shall be paid at the rate(s) of interest and in the manner provided hereunder, unless and until the rate of interest again exceeds the Maximum Lawful Rate, and at that time this paragraph shall again apply. In no event shall the total interest received by any Lender under the Bridge Notes pursuant to the terms hereof exceed the amount that such Lender could lawfully have received had the Bridge Rate of interest due hereunder been calculated for the full term of the Bridge Notes at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated pursuant to this paragraph, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. If, notwithstanding the provisions of this Section 1.10, a court of competent jurisdiction shall determine by a final, non-appealable order that Lender has received interest on the Bridge Notes in excess of the Maximum Lawful Rate, the Investment Manager shall, to the extent permitted by applicable law, promptly apply such excess to the outstanding principal amount of the outstanding Bridge Loan(s) and thereafter, Lender shall refund any excess to Borrower or as such court of competent jurisdiction may otherwise order.

ARTICLE 4

AFFIRMATIVE COVENANTS

Borrower covenants and agrees that from and after the date hereof until the Termination Date:

4.1 Maintenance of Financial Records; Inspections. Borrower agrees to maintain books and records pertaining to their financial matters in such detail, form and scope, for so long as the Investment Manager reasonably may require. Borrower agrees that Investment Manager, accompanied by any Lender (at such Lender’s expense), and/or any agent designated by Investment Manager, upon notice to Borrower (provided that such notice shall not be required after any Default or Event of Default shall have occurred), may enter upon the applicable Borrower’s premises at any time during normal business hours, and from time to time, in order to (i) examine and inspect the books and records of Borrower, and make copies thereof and take extracts therefrom, and (ii) verify, inspect and perform physical counts

and other valuations of the Collateral and any and all records pertaining thereto. Borrower irrevocably authorizes all accountants and third parties to disclose and deliver directly to Investment Manager and Lender, at Borrower’s expense, all financial statements and information, books, records, work papers and management reports generated by them or in their possession regarding Borrower or the Collateral. All costs, fees and expenses incurred by Investment Manager in connection with such examinations, inspections, physical counts and other valuations shall constitute fees reimbursable by Borrower pursuant to Section 1.6 for purposes of this Agreement.

4.2 Further Assurances. Borrower agrees to comply with the requirements of all state and federal laws in order to grant to Investment Manager, for the benefit of Lender, valid and perfected first priority security interests in the Collateral pursuant to the Collateral Documents, subject only to the Permitted Encumbrances. Investment Manager is hereby authorized by Borrower to file any financing statements, continuations and amendments covering the Collateral without Borrower’s signature in accordance with the provisions of the Code. Borrower hereby consents to and ratifies the filing of any financing statements covering the Collateral by Investment Manager on or prior to the Closing Date. Each Borrower agrees to do whatever Investment Manager reasonably may request from time to time, by way of (i) filing notices of liens, financing statements, amendments, renewals and continuations thereof, (ii) cooperating with agents and employees of Investment Manager, (iii) keeping Collateral records, (iv) transferring proceeds of Collateral to Investment Manager’s possession in accordance with the terms of this Agreement and the Collateral Documents and (v) performing such further acts as Investment Manager reasonably may require in order to effect the purposes of this Agreement and the Collateral Documents, including the execution of control agreements with respect to deposit accounts and investment property.

4.3 Insurance and Condemnation.

(a) Required Insurance. Borrower agrees to maintain insurance on the Real Estate, Equipment and Inventory under such policies of insurance, with such insurance companies, in such reasonable amounts and covering such insurable risks, as are at all times reasonably satisfactory to Investment Manager (the “Required Insurance”). All policies covering the Real Estate, Equipment and Inventory are, subject to the rights of any holder of a Permitted Encumbrance having priority over the security interests of Investment Manager, to be made payable solely to Investment Manager, for the benefit of Lender, in case of loss, under a standard non contributory “mortgagee”, “secured party” or “lender’s loss payable” clause or endorsement, and are to contain such other provisions as Investment Manager reasonably may require to fully protect Investment Manager’s interest in the Real Estate, Inventory and Equipment and to any payments to be made under such policies. Each loss payable endorsement in favor of Investment Manager shall provide (x) for not less than thirty (30) days prior written notice to Investment Manager of the exercise of any right of cancellation and (y) that Investment Manager’s right to payment under any property insurance policy will not be invalidated by any act or neglect of, or any breach of warranty or condition by, any Borrower or any other party. If an Event of Default shall have occurred and remain outstanding, Investment Manager, subject to the rights of any holder of a Permitted Encumbrance having priority over the security interests of Investment Manager, shall have the

sole right, in the name of Investment Manager or any Borrower, to file claims under any insurance policies, to receive, receipt and give acquittance for any payments that may be payable thereunder, and to execute any and all endorsements, receipts, releases, assignments, reassignments or other documents that may be necessary to effect the collection, compromise or settlement of any claims under any such insurance policies.

(b) Investment Manager’s Purchase of Insurance. Unless Borrower provides Investment Manager with evidence of the Required Insurance in the manner set forth in Section 4.3(a) above, Investment Manager may purchase insurance at Borrower’s expense to protect Investment Manager’s interests in the Collateral. The insurance purchased by the Investment Manager may, but need not, protect Borrower’s interests in the Collateral, and therefore such insurance may not pay any claim which Borrower makes or any claim which is made against Borrower in connection with the Collateral. Borrower may later request that Investment Manager cancel any insurance purchased by Investment Manager, but only after providing Investment Manager with satisfactory evidence that Borrower has the Required Insurance. If Investment Manager purchases insurance covering all or any portion of the Collateral, Borrower shall be responsible for the costs of such insurance, including interest (at the applicable rate set forth hereunder) and other charges accruing on the purchase price therefor, until the effective date of the cancellation or the expiration of the insurance. The costs of the premiums of any insurance purchased by Investment Manager may exceed the costs of insurance which Borrower may be able to purchase on its/their own. In the event that Investment Manager purchases insurance, Investment Manager will notify Borrower of such purchase within thirty (30) days after the date of such purchase. If, within thirty (30) days after the date of receipt of such notice, Borrower provides Investment Manager with proof that Borrower had the Required Insurance as of the date on which Investment Manager purchased insurance and Borrower has continued at all times thereafter to have the Required Insurance, then Investment Manager agrees to cancel the insurance purchased by Investment Manager.

(c) Application of Insurance and Condemnation Proceeds. So long as no Default or Event of Default shall have occurred and remain outstanding as of the date of Investment Manager’s receipt of any Casualty Proceeds:

(i) Except as may otherwise be provided in any intercreditor or subordination agreement between Investment Manager and another creditor of Borrower, in the event of any loss or damage to any item of Equipment by condemnation, fire or other casualty, if the Casualty Proceeds relating to such condemnation, fire or other casualty exceed $100,000, Borrower may elect (by delivering written notice to Investment Manager within ten (10) Business Days following Investment Manager’s receipt of such Casualty Proceeds) to replace or repair such item of Equipment.

(ii) In the event of any loss or damage to any Real Estate leased by Borrower by condemnation, fire or other casualty, Borrower may use the Casualty Proceeds in the manner required or permitted by the lease agreement relating thereto. In the event of any loss or damage to any Real Estate owned by Borrower by condemnation, fire or other casualty, if the Casualty Proceeds relating to such condemnation, fire or other casualty exceed $100,000, and

so long as Borrower has sufficient business interruption insurance to replace the lost profits of the facilities affected by the condemnation, fire or other casualty, Borrower may elect to repair or replace such Real Estate, subject to the following terms:

(1) If Borrower reasonably determines that the Real Estate may be repaired to substantially the same condition of the Real Estate prior to the condemnation, fire or other casualty, Borrower may elect to repair the Real Estate by delivering written notice to Investment Manager within thirty (30) days following Investment Manager’s receipt of such Casualty Proceeds.

(2) Borrower may elect to replace the Real Estate owned by Borrower only on terms and conditions satisfactory to Investment Manager in its sole discretion.

If a Default or an Event of Default shall have occurred and remain outstanding as of the date of Investment Manager’s receipt of any Casualty Proceeds, or if the Borrower does not or cannot elect to use the Casualty Proceeds in the manner set forth in paragraphs (i) or (ii) above, Investment Manager may, subject to the terms of any intercreditor or subordination agreement between Investment Manager and another creditor of Borrower, and subject to the rights of any holder of a Permitted Encumbrance having priority over the security interests of Investment Manager, apply the Casualty Proceeds to the payment of the Obligations in such manner and in such order as Investment Manager may elect in its sole discretion.

4.4 Payment of Taxes. Borrower agrees to pay when due all Taxes lawfully levied, assessed or imposed upon Borrower or the Collateral (including all sales taxes collected by Borrower on behalf of Borrower’s customers in connection with sales of Inventory and all payroll taxes collected by such Borrower on behalf of such Borrower’s employees), unless Borrower is contesting such Taxes in good faith, by appropriate proceedings, and is maintaining adequate reserves for such Taxes in accordance with GAAP. Notwithstanding the foregoing, if a lien securing any Taxes is filed in any public office and such lien is not a Permitted Tax Lien, then the applicable Borrower shall pay all taxes secured by such lien immediately and remove such lien of record promptly. Pending the payment of such taxes and removal of such lien, Investment Manager may, at its election and without curing or waiving any Event of Default which may have occurred as a result thereof, pay such taxes on behalf of such Borrower, and the amount paid by Investment Manager shall become an Obligation which is due and payable on demand by Investment Manager.

4.5 Compliance With Laws.

(a) Borrower agrees to comply with all federal, state and local acts, rules and regulations, and all orders of any federal, state or local legislative, administrative or judicial body or official, if the failure to so comply would be reasonably likely to have a Material Adverse Effect, provided that Borrower may contest any acts, rules, regulations, orders and directions of such bodies or officials in any reasonable manner which Investment Manager determines, in the exercise of its reasonable business judgment, will not materially and adversely effect Investment Manager’s or Lender’s rights or priorities in the Collateral.

(b) Without limiting the generality of the foregoing, Borrower agrees to comply with all environmental statutes, acts, rules, regulations or orders, as presently existing or as adopted or amended in the future, applicable to the ownership and/or use of its/their real property and operation of its business, if the failure to so comply would be reasonably likely to have a Material Adverse Effect. Borrower shall not be deemed to have breached any provision of this Section 4.5(b) if (x) the failure to comply with the requirements of this Section 4.5 resulted from good faith error or innocent omission, (y) Borrower promptly commences and diligently pursues a cure of such breach and (z) such failure is cured within thirty (30) days following Borrower’s receipt of notice from Investment Manager of such failure, or if such breach cannot in good faith be cured within thirty (30) days following Borrower’s receipt of such notice, then such breach is cured within a reasonable time frame based on the extent and nature of the breach and the necessary remediation, and in conformity with any applicable consent order, consensual agreement and applicable law.

4.6 Notices Concerning Environmental, Employee Benefit and Pension Matters. Borrower agrees to notify Investment Manager in writing of:

(a) any expenditure (actual or anticipated) by any Borrower in excess of $100,000 for environmental clean up, environmental compliance or environmental testing and the impact of said expenses on Borrower’s working capital;

(b) Borrower’s receipt of notice from any local, state or federal authority advising such Borrower of any environmental liability (real or potential) arising from Borrower’s operations, its premises, its waste disposal practices, or waste disposal sites used by Borrower; and

(c) Borrower’s receipt of notice from any governmental agency or any sponsor of any “multiemployer plan” (as that term is defined in ERISA) to which Borrower has contributed, relating to any ERISA Event.

Borrower agrees to provide Investment Manager promptly with copies of all such notices and other information pertaining to any matter set forth above if Investment Manager so requests.

4.7 Business Qualification. Borrower agrees to qualify to do business, and to remain qualified to do business and in good standing, in each jurisdiction where the failure to so qualify, or to remain qualified or in good standing, would have, or would be reasonably likely to have, a Material Adverse Effect.

4.8 Anti-Money Laundering and Terrorism Regulations. Borrower agrees to comply with all applicable anti-money laundering and terrorism laws, regulations and executive orders in effect from time to time (including, without limitation, the USA Patriot Act (Pub. L. No. 107-56)). Borrower also agrees to ensure that no Person who owns a controlling interest in or otherwise controls either VCI or VCAC, as the case may be, is a Person designated under Section 1(b), (c) or (d) of Executive Order No. 13224 (issued September 23, 2001) or any other similar Executive Order. Borrower acknowledges that

Investment Manager’s and Lender’s performance hereunder is subject to compliance with all such laws, regulations and executive orders, and in furtherance of the foregoing, Borrower agrees to provide to Investment Manager and Lender all information about Borrower’s ownership, officers, directors, customers and business structure as Investment Manager and Lender reasonably may require to comply with, such laws, regulations and executive orders.

4.9 Maintenance of Properties. Borrower will maintain or cause to be maintained in good repair, working order and condition all material properties used in the business of Borrower and its Subsidiaries (as the case may be) and will make or cause to be made all appropriate repairs, renewals and replacements thereof, ordinary wear and tear excepted.

4.10 Lender Meeting. Borrower will participate and will cause its key management personnel (and those of its Subsidiaries as the case may be) to participate in a meeting with Investment Manager and Lender at least once during each year, which meeting shall be held at such time and such place as may be reasonably requested by Investment Manager.

4.11 Organizational Existence. Except as permitted by Section 5.4, Borrower will and will cause its Subsidiaries to at all times preserve and keep in full force and effect its organizational existence and all rights and franchises the absence of which could reasonably be expected to have a Material Adverse Effect.

4.12 Landlords’ Agreements, Mortgagee Agreements, Bailee Letters and Real Estate Purchases. Borrower shall use its best efforts to obtain a landlord’s agreement, mortgagee agreement or bailee letter, as applicable, from each lessor of leased property, mortgagee of owned property or bailee with respect to any warehouse, processor or converter facility or other location where Collateral is stored or located, which agreement or letter shall contain a waiver or subordination of all Liens or claims that the landlord, mortgagee or bailee may assert against the Collateral at that location, and shall otherwise be reasonably satisfactory in form and substance to Investment Manager. After the Closing Date, no real property or warehouse space shall be leased by Borrower or any Subsidiary of Borrower and no Inventory shall be shipped to a processor or converter under arrangements established after the Closing Date without the prior written consent of Investment Manager or, unless and until a satisfactory landlord agreement or bailee letter, as appropriate, shall first have been obtained with respect to such location. Borrower shall and shall cause each of its Subsidiaries (as the case may be) to timely and fully pay and perform their obligations under all leases and other agreements with respect to each leased location or public warehouse where any Collateral is or may be located. In the event Borrower acquires a fee interest in real property after the Closing Date, Borrower shall deliver to Investment Manager a fully executed mortgage or deed of trust over such real property in form and substance satisfactory to Investment Manager, together with such title insurance policies, surveys, appraisals, evidence of insurance, legal opinions, environmental assessments and other documents and certificates as shall be reasonably requested by Investment Manager.

4.13 New Subsidiaries. Borrower shall (a) cause each Person, upon its becoming a Subsidiary of any Borrower after the date of this Agreement (provided that this shall not be construed to constitute consent by Lender to any transaction not expressly permitted by the terms of this Agreement), promptly to guaranty the Obligations and to grant to Investment Manager, for the benefit of Investment Manager and Lender, a security interest in the real, personal and mixed property of such Person to secure the Obligations and (b) pledge, or cause to be pledged, to Investment Manager, for the benefit of Investment Manager and Lender, all of the Stock of such Subsidiary owned by any Borrower to secure the Obligations. The documentation for such guaranty, security and pledge shall be substantially similar to the Loan Documents executed concurrently herewith, including pursuant to the form of Joinder Agreement attached as Exhibit 4.13 hereto, with such modifications as are reasonably requested by Investment Manager.

4.14 Board Observer Rights. Borrower shall permit Lender to have one representative present (whether in person or by telephone) in an observer capacity at all meetings (whether in person or via teleconference) of the respective Board of Directors of each of VCI, VCAC and all Subsidiaries of Borrower, if any (collectively, the “Respective Boards”). Borrower shall send to such representative all of the notices, information and other materials that are distributed to the directors on the Respective Boards and shall provide the Lender representative with a notice and agenda of each meeting of the Respective Boards, all at the same time and in the same manner as such notices, agenda, information and other materials are provided to the directors on the Respective Boards.

In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, during the continuance of any Event of Default, Lender is hereby authorized by Borrower at any time or from time to time, with reasonably prompt subsequent notice to Borrower (any prior or contemporaneous notice being hereby expressly waived) to set off and to appropriate and to apply any and all (A) balances held by Lender at any of its offices for the account of Borrower or any of its Subsidiaries (regardless of whether such balances are then due to such Borrower or Subsidiary), and (B) other property at any time held or owing by Lender to or for the credit or for the account of Borrower or any of its Subsidiaries, against and on account of any of the Obligations; except that Lender shall not exercise any such right without the prior written consent of Investment Manager. Lender, in exercising a right to set off or otherwise receiving any payment on account of the Obligations, shall deliver such amounts to Investment Manager and Investment Manager shall apply such funds to the payment of the Obligations in accordance with Section 7.5.

7.5 Application of Proceeds after Default. Notwithstanding anything to the contrary contained in this Agreement, upon the occurrence and during the continuance of an Event of Default, (a) Borrower irrevocably waives the right to direct the application of any and all payments at any time or times thereafter received by Lender or Investment Manager from or on behalf of Borrower, and Investment Manager shall have the continuing and exclusive right to apply and to reapply any and all payments received at any time or times after the occurrence and during the continuance of an Default or Event of Default against the Obligations in such manner as Investment Manager may deem advisable notwithstanding any previous application by Investment Manager and (b) in the absence of a specific determination by Investment Manager with respect thereto, the proceeds of any sale of, or

other realization upon, all or any part of the Collateral shall be applied in accordance with Section 1.9 hereof. Any balance remaining shall be delivered to Borrower or to whomever may be lawfully entitled to receive such balance or as a court of competent jurisdiction may direct.

ARTICLE 8

ASSIGNMENT

8.1 Assignment.

(a) Subject to the terms of this Section 8.1, Lender may make an assignment, at any time or times, of the Loan Documents, the Loans or any portion thereof or interest therein, including Lender’s rights, title, interests, remedies, powers or duties thereunder. Any assignment by Lender shall: (i) require the consent of Investment Manager and the execution of an assignment agreement in form and substance reasonably satisfactory to, and acknowledged by, Investment Manager); and (iii) be conditioned on such assignee Lender representing to the assigning Lender and Investment Manager that it is purchasing the Loans or portion of the Loans to be assigned to it for its own account, for investment purposes and not with a view to the distribution thereof. In the case of an assignment by Lender under this Section 8.1, the assignee shall have, to the extent of such assignment, the same rights, benefits and obligations as Lender hereunder. The assigning Lender shall be relieved of its obligations hereunder with respect to the assigned portion of the Loans from and after the date of such assignment. Borrower hereby acknowledges and agrees that any assignment shall give rise to a direct obligation of Borrower to the assignee and that the assignee shall be considered to be a “Lender.” In the event Investment Manager or Lender assigns or otherwise transfers all or any part of the Obligations, Investment Manager or Lender shall so notify Borrower and Borrower shall, upon the request of Investment Manager or Lender, execute new notes in exchange for the Note(s) being assigned. Notwithstanding the foregoing provisions of this Section 8.1(a), Lender may at any time pledge the Obligations held by it and Lender’s rights under this Agreement and the other Loan Documents to a Federal Reserve Bank.

(b) Borrower shall assist Lender as required to enable the assigning Lender to effect any such assignment, including the execution and delivery of any and all agreements, notes and other documents and instruments as shall be requested and the prompt preparation of informational materials for, and the participation of management in meetings with potential assignees, all on a reasonable timetable established by Investment Manager in its sole discretion. Borrower shall certify the correctness, completeness and accuracy in all material respects of all written descriptions of Borrower and its affairs contained in any selling materials provided by Borrower or any of its Subsidiaries.

(c) Lender may furnish any information concerning Borrower in the possession of Lender from time to time to assignees and participants (including prospective assignees and participants); provided that Lender shall obtain from assignees or participants confidentiality covenants substantially equivalent to those contained in Section 10.12.

ARTICLE 9

PROVISIONS RELATED TO INVESTMENT MANAGER

9.1 Appointment. Lender hereby designates and appoints Investment Manager as its agent under this Agreement and the other Loan Documents, and Lender hereby irrevocably authorizes Investment Manager to execute and deliver the Collateral Documents and 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 as are set forth herein or therein, together with such other powers as are reasonably incidental thereto. Investment Manager is authorized and empowered to amend, modify, or waive any provisions of this Agreement or the other Loan Documents on behalf of Lender subject to the requirement that Lender’s consent be obtained in certain instances as provided in this Article 9 and Section 10.2. The provisions of this Article 9 are solely for the benefit of Investment Manager and Lender and neither Borrower nor any other Person shall have any rights as a third party beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement, Investment Manager shall act solely as agent of Lender and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for Borrower. Investment Manager may perform any of its duties hereunder, or under the Loan Documents, by or through its agents or employees.

9.2 Reliance. Investment Manager shall be entitled to rely, and shall be fully protected in relying, upon any written or oral notices, statements, certificates, orders or other documents or any telephone message or other communication (including any writing, telex, fax 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 or any of the Loan Documents and its duties hereunder or thereunder. Investment Manager shall be entitled to rely upon the advice of legal counsel, independent accountants, and other experts selected by Investment Manager in its sole discretion.

9.3 Successor Investment Manager.

(a) Resignation. Investment Manager may resign from the performance of all its agency functions and duties hereunder at any time by giving at least thirty (30) Business Days’ prior written notice to Borrower and Lender. Such resignation shall take effect upon the acceptance by a successor Investment Manager of appointment pursuant to clause (b) below or as otherwise provided in clause (b) below.

(b) Appointment of Successor. Upon any such notice of resignation pursuant to clause (a) above, Lender shall appoint a successor Investment Manager which, unless an Event of Default has occurred and is continuing, shall be acceptable to Borrower (Borrower’s approval not to be unreasonably conditioned, delayed or withheld). If a successor Investment Manager shall not have been so appointed within the thirty (30) Business Day period referred to in clause (a) above, the retiring Investment Manager, upon notice to Borrower, shall then appoint a successor Investment Manager who shall serve as Investment Manager until such time, if any, as Lender appoints a successor Investment Manager as provided above.

(c) Successor Investment Manager. Upon the acceptance of any appointment as Investment Manager under the Loan Documents by a successor Investment Manager, such successor Investment Manager shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Investment Manager, and the retiring Investment Manager shall be discharged from its duties and obligations under the Loan Documents. After any retiring Investment Manager’s resignation as Investment Manager, the provisions of this Article 9 shall continue to inure to its benefit as to any actions taken or omitted to be taken by it in its capacity as Investment Manager.

9.4 Collateral Matters.

(a) Release of Collateral. Lender hereby irrevocably authorizes Investment Manager, at its option and in its sole discretion, to release any Lien granted to or held by Investment Manager upon any Collateral (x) upon payment and satisfaction of all Obligations (other than contingent indemnification obligations to the extent no claims giving rise thereto have been asserted) or (y) constituting property being sold or disposed of if Borrower certifies to Investment Manager that the sale or disposition is made in compliance with the provisions of this Agreement (and Investment Manager may rely in good faith conclusively on any such certificate, without further inquiry).

(b) Confirmation of Authority; Execution of Releases. Without in any manner limiting Investment Manager’s authority to act without any specific or further authorization or consent by Lender (as set forth in Section 9.4(a)), Lender agrees to confirm in writing, upon request by Investment Manager or Borrower, the authority to release any Collateral conferred upon Investment Manager under clauses (x) and (y) of Section 9.4(a). Upon receipt by Investment Manager of any required confirmation from Lender of its authority to release any particular item or types of Collateral, and upon at least ten (10) Business Days’ prior written request by Borrower, Investment Manager shall (and is hereby irrevocably authorized by Lender to) execute such documents as may be necessary to evidence the release of the Liens granted to Investment Manager upon such Collateral; provided, however, that (x) Investment Manager shall not be required to execute any such document on terms which, in Investment Manager’s opinion, would expose Investment Manager to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (y) such release shall not in any manner discharge, affect or impair the Obligations or any Liens upon, all interests retained by Borrower, including the proceeds of any sale, all of which shall continue to constitute part of the Collateral.

(c) Absence of Duty. Investment Manager shall have no obligation whatsoever to Lender or any other Person to assure that the property covered by the Collateral Documents exists or is owned by Borrower or is cared for, protected or insured or has been encumbered or that the Liens granted to Investment Manager have been properly or sufficiently or lawfully created, perfected, protected or enforced 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 Investment Manager in this Section 9.4 or in any of the Loan

Documents, it being understood and agreed that in respect of the property covered by the Collateral Documents or any act, omission or event related thereto, Investment Manager may act in any manner it may deem appropriate, in its sole discretion, given Investment Manager’s own interest in property covered by the Collateral Documents and that Investment Manager shall have no duty or liability whatsoever to Lender, provided that Investment Manager shall exercise the same care which it would in dealing with loans for its own account.

9.5 Agency for Perfection. Investment Manager and Lender hereby appoint each other Lender as agent for the purpose of perfecting Investment Manager’s security interest in assets which, in accordance with the Code in any applicable jurisdiction, can be perfected by possession or control. Should Lender obtain possession or control of any such assets, Lender shall notify Investment Manager thereof, and, promptly upon Investment Manager’s request therefor, shall deliver such assets to Investment Manager or in accordance with Investment Manager’s instructions or transfer control to Investment Manager in accordance with Investment Manager’s instructions. Lender agrees that it will not have any right individually to enforce or seek to enforce any Collateral Document or to realize upon any collateral security for the Loans unless instructed to do so by Investment Manager in writing, it being understood and agreed that such rights and remedies may be exercised only by Investment Manager.

9.6 Notice of Default. Investment Manager shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless Investment Manager shall have received written notice from Lender or Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. Investment Manager will use reasonable efforts to notify Lender of its receipt of any such notice, unless such notice is with respect to defaults in the payment of principal, interest and Fees, in which case Investment Manager will notify Lender of its receipt of such notice. Investment Manager shall take such action with respect to such Default or Event of Default as may be requested by Lender in accordance with Article 7. Unless and until Investment Manager has received any such request, Investment Manager may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interests of Lender.

9.7 Lender Actions Against Collateral. With respect to any action by Investment Manager to enforce the rights and remedies of Investment Manager and Lender under this Agreement and the other Loan Documents, Lender hereby consents to the jurisdiction of the court in which such action is maintained, and agrees to deliver its Notes to Investment Manager to the extent necessary to enforce the rights and remedies of Investment Manager for the benefit of Lender under the mortgages or similar Liens or encumbrances in accordance with the provisions hereof.

9.8 Payment; Information; Actions in Concert.

(a) Return of Payments.

(i) If Investment Manager pays an amount to Lender under this Agreement in the belief or expectation that a related payment has been or will be received by Investment Manager from Borrower and such related payment is not received by Investment Manager, then Investment Manager will be entitled to recover such amount from Lender on demand without setoff, counterclaim or deduction of any kind.

(ii) If Investment Manager determines at any time that any amount received by Investment Manager under this Agreement must be returned to Borrower or paid to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement or any other Loan Document, Investment Manager will not be required to distribute any portion thereof to Lender. In addition, Lender will repay to Investment Manager on demand any portion of such amount that Investment Manager has distributed to Lender, together with interest at such rate, if any, as Investment Manager is required to pay to Borrower or such other Person, without setoff, counterclaim or deduction of any kind.

(b) Dissemination of Information. Investment Manager shall use reasonable efforts to provide Lender with any notice of Default or Event of Default received by Investment Manager from, or delivered by Investment Manager to, Borrower, with notice of any Event of Default of which Investment Manager has actually become aware and with notice of any action taken by Investment Manager following any Event of Default; provided, that Investment Manager shall not be liable to Lender for any failure to do so.

ARTICLE 10

MISCELLANEOUS

10.1 Indemnities. Borrower agrees (together with its Subsidiaries, on a joint and several basis) to indemnify, pay, and hold Investment Manager, Lender and their respective officers, directors, employees, agents, and attorneys (the “Indemnitees”) harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs and expenses (including all reasonable fees and expenses of counsel to such Indemnitees) of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Indemnitee as a result of such Indemnitees being a party to this Agreement or the transactions consummated pursuant to this Agreement; provided, that Borrower shall have no obligation to an Indemnitee hereunder with respect to liabilities to the extent resulting from the gross negligence or willful misconduct of that Indemnitee as determined by a court of competent jurisdiction. If and to the extent that the foregoing undertaking may be unenforceable for any reason, Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

10.2 Amendments and Waivers. Except for actions expressly permitted to be taken by Investment Manager, no amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, or any consent to any departure by Borrower therefrom, shall in any event be effective unless the same shall be in writing and

signed by Borrower, Investment Manager and Lenders owning a majority of the then outstanding principal amounts of the Notes.

Any notice or other communication required shall be in writing addressed to the respective party as set forth below and may be personally served, telecopied, sent by overnight courier service or U.S. mail and shall be deemed to have been given: (a) if delivered in person, when delivered; (b) if delivered by fax, on the date of transmission if transmitted on a Business Day before 4:00 p.m. Eastern Time; (c) if delivered by overnight courier, one (1) Business Day after delivery to the courier properly addressed; or (d) if delivered by U.S. mail, four (4) Business Days after deposit with postage prepaid and properly addressed.

10.4 Obligations Absolute; Failure or Indulgence Not Waiver; Remedies Cumulative. The payment and performance by Borrower of all of the Obligations shall be absolute and unconditional, irrespective of any defense or rights of set-off, recoupment or

counterclaim Borrower might otherwise have against Investment Manager or Lender, and Borrower shall pay and perform all of the Obligations, free of any deductions and without abatement, diminution, recoupment, counterclaim or set-off. Until payment in full of all of the Obligations, Borrower shall (a) not suspend or discontinue any payments required pursuant to the Notes, this Agreement or any other Loan Document; and (b) perform and observe all of the other terms and provisions of this Agreement or any other Loan Documents. No failure or delay on the part of Investment Manager or Lender to exercise, nor any partial exercise of, any power, right or privilege hereunder or under any other Loan Documents shall impair such power, right, or privilege or be construed to be a waiver of any Default or Event of Default. All rights and remedies existing hereunder or under any other Loan Document are cumulative to and not exclusive of any rights or remedies otherwise available.

10.5 Marshaling; Payments Set Aside. Neither Investment Manager nor Lender shall be under any obligation to marshal any assets in payment of any or all of the Obligations. To the extent that Borrower makes payment(s) or Investment Manager enforces its Liens or Investment Manager or Lender exercises its right of set-off, and such payment(s) or the proceeds of such enforcement or set-off is subsequently invalidated, declared to be fraudulent or preferential, set aside, or required to be repaid by anyone, then to the extent of such recovery, the Obligations or part thereof originally intended to be satisfied, and all Liens, rights and remedies therefor, shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or set off had not occurred.

10.6 Severability. The invalidity, illegality, or unenforceability in any jurisdiction of any provision under the Loan Documents shall not affect or impair the remaining provisions in the Loan Documents. Furthermore, in lieu of any such provision, there shall be added automatically as part of the applicable agreement a legal and enforceable provision as similar in terms to such provision as may be possible.

10.7 Headings. Section and subsection headings are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purposes or be given substantive effect.

This Agreement and the other Loan Documents shall be binding on and shall inure to the benefit of Borrower, Investment Manager, Lender and their respective successors and assigns (including, in the case of Borrower, a debtor-in-possession on behalf of such Borrower), except as otherwise provided herein or therein. Borrower may not assign, transfer, hypothecate or otherwise convey its rights, benefits, obligations or duties hereunder or under any of the other Loan Documents without the prior express written consent of Investment Manager and Lender owning a majority in then outstanding principal amount of the Note(s).

Borrower agrees that neither Investment Manager nor Lender shall have liability to Borrower (whether sounding in tort, contract or otherwise) for losses suffered by Borrower in connection with, arising out of, or in any way related to the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless and to the extent that it is determined that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought as determined by a final non-appealable order by a court of competent jurisdiction. Neither Investment Manager nor Lender shall have any liability with respect to, and Borrower hereby waives, releases and agrees not to ▇▇▇ for, any special, indirect or consequential damages suffered by Borrower in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

(ii) Any and all rights that would result in such Person being deemed a “creditor” under the United States Code of any other Borrower or any other Person, on account of payments made or obligations performed by such Person; and

Until such time as the Obligations have been satisfied in full, any claim, right or remedy which it may now have or hereafter acquire against any other Borrower that arises hereunder and/or from the performance by it hereunder including any claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification, or participation in any claim, right or remedy of Lender against any Borrower or any collateral security which Lender now has or may hereafter acquire, whether or not such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise.

IN WITNESS WHEREOF, the undersigned parties to this Credit Agreement have hereunto set their hands as of the day and year first above written.
