The parties agree as follows:

1.	ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement will be construed following GAAP. Calculations and determinations must be made following GAAP. The term “financial statements” includes the notes and schedules. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document.

2.	LOAN AND TERMS OF PAYMENT

2.1	Promise to Pay.

Borrowers jointly and severally promise to pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1

Revolving Advances.

(a) Bank will make Advances not exceeding (i) the lesser of (A) the Committed Revolving Line or (B) the Borrowing Base. Amounts borrowed under this Section may be repaid and reborrowed during the term of this Agreement. All advances shall be evidenced by the Revolving Promissory Note to be executed and delivered by Borrowers to Bank on the Closing Date and shall be repaid in accordance with the terms of the Revolving Promissory Note.

(b) To obtain an Advance, Company must notify Bank by facsimile or telephone by 3:00 p.m. Eastern time on the Business Day the Advance is to be made. Company must promptly confirm the notification by delivering to Bank the Loan Payment/Advance Request Form attached as Exhibit B (the “Payment/Advance Form”). Bank will credit Advances to Company’s deposit account. Bank may make Advances under this Agreement based on instructions from a Responsible Officer of Company or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank reasonably believes is a Responsible Officer of Company or designee. Borrowers will indemnify Bank for any loss Bank suffers due to such reliance.

(d) Bank’s obligation to lend the undisbursed portion of the Committed Revolving Line will terminate if, in Bank’s sole, but reasonable, discretion, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospect of repayment of the Obligations, or there has been any material

adverse deviation by Borrowers from the most recent business plan of Borrowers presented to and accepted by Bank prior to the execution of this Agreement.

2.2

Overadvances.

If Borrowers’ Obligations under Section 2.1.1 exceed the lesser of either (i) the Committed Revolving Line or (ii) the Borrowing Base, Borrowers shall immediately pay Bank the excess.

2.3

Interest Rate, Payments.

(a) Interest Rate. Advances accrue interest on the outstanding principal balance in accordance with the Revolving Promissory Note. After an Event of Default, Obligations accrue interest at five percent (5%) above the rate effective immediately before the Event of Default. The interest rate on the Obligations increases or decreases when the Prime Rate changes. Interest is computed on a 360 day year for the actual number of days elapsed.

(b) Payments. Interest due on the Committed Revolving Line is payable on the fifth (5^th) day of each month. Bank may debit any of any Borrower’s deposit accounts including Account Number 3300020208 for principal and interest payments owing or any amounts any Borrower owes Bank under any of the Loan Documents. Bank will promptly notify Company when it debits any such accounts. These debits are not a set-off. Payments received after 12:00 noon Eastern time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest corresponding to the intervening days accrue.

(c) Lockbox. All proceeds of Collateral shall be deposited by each Borrower into a lockbox account, or such other “blocked account” as Bank may specify, pursuant to a blocked account agreement in the form attached hereto as Exhibit E.

2.4

Joint Liability.

Each Person included in the term “Borrower” hereby covenants and agrees with Bank as follows:

(a) The Obligations include all present and future indebtedness, duties, obligations, and liabilities under the Loan Documents, whether now existing or contemplated or hereafter arising, of any one or more of the Borrowers.

(b) Reference in this Agreement and the other Loan Documents to the “Borrower” or otherwise with respect to any one or more of the Persons now or hereafter included in the definition of “Borrower” shall mean each and every such Person and any one or more of such Persons, jointly and severally, unless the context requires otherwise.

(c) Each Person included in the term “Borrower” in the discretion of its respective management is to agree among themselves as to the allocation of the benefits of the proceeds of the Committed Revolving Line, provided, however, that each such Person shall be deemed to have represented and warranted to Bank at the time of allocation that each benefit and use of proceeds is permitted under this Agreement.

(d) For administrative convenience, each Person included in the term “Borrower” hereby irrevocably appoints the Company as each Borrower’s attorney-in-fact, with power of

substitution (with the prior written consent of Bank in the exercise of its sole and absolute discretion), in the name of the Company or in the name of any Borrower or otherwise to take any and all actions with respect to this Agreement, the other Loan Documents, the Obligations and/or the Collateral (including, without limitation, the proceeds thereof) as the Company may so elect from time to time, including, without limitation, actions to (i) request advances under the Committed Revolving Line, and direct Bank to disburse or credit the proceeds of any Advance directly to an account of the Company, any one or more of such Persons or otherwise, which direction shall evidence the making of such Advance and shall constitute the acknowledgment by each such Person of the receipt of the proceeds of such Advance, (ii) enter into, execute, deliver, amend, modify, restate, substitute, extend and/or renew this Agreement, any other Loan Documents, security agreements, mortgages, deposit account agreements, instruments, certificates, waivers, letter of credit applications, releases, documents and agreements from time to time, and (iii) endorse any check or other item of payment in the name of such Person or in the name of the Company. The foregoing appointment is coupled with an interest, cannot be revoked without the prior written consent of Bank, and may be exercised from time to time through the Company’s Responsible Officer, or other Person or Persons designated by the Company to act from time to time on behalf of the Company.

(e) Each Person included in the term “Borrower” hereby irrevocably authorizes Bank to make Advances to any one or more of such Persons, pursuant to the provisions of this Agreement upon the written, oral or telephone request of any one or more of the Persons who is from time to time a Responsible Officer of the Company under the provisions of the most recent certificate of corporate resolutions and/or incumbency of the Person included in the term “Borrower” on file with Bank and also upon the written, oral or telephone request of any one of the Persons who is from time to time a Responsible Officer of the Company under the provisions of the most recent certificate of corporate resolutions and/or incumbency for the Company on file with Bank.

(f) Bank assumes no responsibility or liability for any errors, mistakes, and/or discrepancies in the oral, telephonic, written or other transmissions of any instructions, orders, requests and confirmations by any one or more of the Persons included in the term “Borrower” in connection with any Credit Extension or any other transaction in connection with the provisions of this Agreement.

2.5

Inter-Company Debt, Contribution.

Without implying any limitation on the joint and several nature of the Obligations, Bank agrees that, notwithstanding any other provision of this Agreement, the Persons included in the term “Borrower” may create reasonable inter-company indebtedness between or among the Persons included in the term “Borrower” with respect to the allocation of the benefits and proceeds of the Credit Extensions under this Agreement. The Persons included in the term “Borrower” agree among themselves, and Bank consents to that agreement, that each such Person shall have rights of contribution from all of the such Persons to the extent such Person incurs Obligations in excess of the proceeds of the Advances received by, or allocated to such Person. All such indebtedness and rights shall be, and are hereby agreed by the Persons included in the term “Borrower” to be, subordinate in priority and payment to the indefeasible repayment in full in cash of the Obligations, and, unless Bank agrees in writing otherwise, shall not be exercised or repaid in whole or in part until all of the Obligations have been indefeasibly paid in full in cash. Each Person included in the term “Borrower” agrees that all of such inter-company

indebtedness and rights of contribution are part of the Collateral and secure the Obligations. Each Person included in the term “Borrower” hereby waives all rights of counter claim, recoupment and offset between or among themselves arising on account of that indebtedness and otherwise. No Person included in the term “Borrower” shall evidence the inter-company indebtedness or rights of contribution by note or other instrument, and shall not secure such indebtedness or rights of contribution with any Lien or security.

2.6

Borrowers are Integrated Group.

Each Person included in the term “Borrower” hereby represents and warrants to Bank that each of them will derive benefits, directly and indirectly, from each Credit Extension, both in their separate capacity and as a member of the integrated group to which each such Person belongs and because the successful operation of the integrated group is dependent upon the continued successful performance of the functions of the integrated group as a whole, because (i) the terms of the Credit Extension provided under this Agreement are more favorable than would otherwise would be obtainable by such Persons individually, and (ii) the additional administrative and other costs and reduced flexibility associated with individual loan arrangements which would otherwise be required if obtainable would substantially reduce the value to such Persons of the Credit Extension.

2.7

Primary Obligations.

The obligations and liabilities of each Person included in the term “Borrower” shall be primary, direct and immediate, shall not be subject to any counterclaim, recoupment, set off, reduction or defense based upon any claim that such Person may have against any one or more of the other Persons included in the term “Borrower”, Bank and/or any other guarantor and shall not be conditional or contingent upon pursuit or enforcement by Bank of any remedies it may have against Persons included in the term “Borrower” with respect to this Agreement, or any of the other Loan Documents, whether pursuant to the terms thereof or by operation of law. Without limiting the generality of the foregoing, Bank shall not be required to make any demand upon any of the Persons included in the term “Borrower”, or to sell the Collateral or otherwise pursue, enforce or exhaust its or their remedies against the Persons included in the term “Borrower” or the Collateral either before, concurrently with or after pursuing or enforcing its rights and remedies hereunder. Any one or more successive or concurrent actions or proceedings may be brought against each Person included in the term “Borrower”, either in the same action, if any, brought against any one or more of the Persons included in the term “Borrower” or in separate actions or proceedings, as often as Bank may deem expedient or advisable. Without limiting the foregoing, it is specifically understood that any modification, limitation or discharge of any of the liabilities or obligations of any one or more of the Persons included in the term “Borrower”, any other guarantor or any obligor under any of the Loan Documents, arising out of, or by virtue of, any bankruptcy, arrangement, reorganization or similar proceeding for relief of debtors under federal or state law initiated by or against any one or more of the Persons included in the term “Borrower”, in their respective capacities as borrowers and guarantors under this Agreement, or under any of the Loan Documents shall not modify, limit, lessen, reduce, impair, discharge, or otherwise affect the liability of any other Borrower under this Agreement in any manner whatsoever, and this Agreement shall remain and continue in full force and effect. It is the intent and purpose of this Agreement that each Person included in the term “Borrower” shall and does hereby waive all rights and benefits which might accrue to any other guarantor by reason of any such proceeding, and the Persons included in the term “Borrower” agree that they shall be liable for the full amount of the obligations and liabilities under this Agreement regardless of, and

irrespective to, any modification, limitation or discharge of the liability of any one or more of the Persons included in the term “Borrower”, any other guarantor or any other obligor under any of the Loan Documents, that may result from any such proceedings.

2.8

Fees.

Borrowers will pay:

(a) Facility Fee. A fully earned, nonrefundable fee in the amount of Thirty Thousand Dollars ($30,000).

Borrowers shall pay to Bank a fee (collectively, the “Unused Line Fees” and individually, a “Unused Line Fee”) in an amount equal to fifteen hundredths of one percent (0.15%) per annum of the average daily unused and undisbursed portion of the Committed Revolving Line accruing during each month.

9.	BANK’S RIGHTS AND REMEDIES

9.1

Rights and Remedies.

When an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following:

(a) Declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank);

(b) Stop advancing money or extending credit for any Borrower’s benefit under this Agreement or under any other agreement between any Borrower and Bank;

(c) Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Bank in good faith considers advisable;

(d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrowers will assemble the Collateral if Bank requires and make it available as Bank designates. Bank may lawfully enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Each Borrower grants Bank a license to lawfully enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies;

(e) Apply to the Obligations any (i) balances and deposits of any Borrower with Bank or its Affiliate it holds, or (ii) amount held by Bank owing to or for the credit or the account of any Borrower;

(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is granted a non-exclusive, royalty-free license or other right to use, without charge, each Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, each Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; and

(g) Dispose of the Collateral according to the Code.

9.2

Power of Attorney.

Effective only when an Event of Default occurs and during its continuance, each Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse any Borrower’s name on any checks or other forms of payment or security; (ii) sign each Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under any Borrower’s insurance policies; (iv) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the power of attorney to sign each Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Bank’s appointment as each Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

9.3

Accounts Collection.

When an Event of Default occurs and during its continuance, Bank may notify any Person owing any Borrower money of Bank’s security interest in the funds and verify the amount of the Account. Each Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit.

9.4

Bank Expenses.

If any Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain insurance policies required in Section 6.5 and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then applicable rate and secured by the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

9.5

Bank’s Liability for Collateral.

If Bank complies with reasonable banking practices and the Code, it is not liable for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Each Borrower bears all risk of loss, damage or destruction of the Collateral.

9.6

Remedies Cumulative.

Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay is not a waiver, election, or acquiescence. No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.

9.7

Demand Waiver.

Following an Event of Default and during the continuance thereof, with respect to the Obligations under the Loan Documents, each Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which any Borrower is liable.

10.

A party may change its notice address by giving the other party written notice.
