The Bank has made or may make one or more loans ( each, a “Loan” and collectively, the “Loans”) to the Borrower subject to the terms and conditions and in reliance upon the representations and warranties of the Borrower set forth in this Agreement. Each Loan shall be used for business purposes (and not for personal, family or household use) and is or will be evidenced by a promissory note or notes of the Borrower and all renewals, extensions, amendments and restatements thereof (collectively, the “Notes”) acceptable to the Bank, which shall set forth the interest rate, repayment and other provisions of the respective Loan, the terms of which are incorporated into this Agreement by reference.

The Loans governed by this Agreement shall include the Loans specifically described below, if any, and any additional lines of credit or term loans that the Bank has made or may, in its sole discretion, make to the Borrower in the future.

1.1. Line of Credit. One of the Loans governed by this Agreement is a committed senior secured revolving line of credit facility under which the Borrower may request and the Bank will make advances to the Borrower from time to time, and the Borrower may borrow, repay, and reborrow, subject to the terms and conditions of this Agreement and the Revolving Line of Credit Note dated of even date herewith (the “Line of Credit Note”), until the Expiration Date, in an aggregate amount outstanding at any time not to exceed $20,000,000.00, with an option to increase the facility upon request by the Borrower and approval by the Bank, in its discretion, by an additional $10,000,000 (the “Line of Credit”). The “Expiration Date” shall have the meaning set forth in the Line of Credit Note. The Borrower acknowledges and agrees that in no event will the Bank be under any obligation to extend or renew the Line of Credit beyond the Expiration Date.

All advances and other credit extensions under the Line of Credit will be used by the Borrower for (i) a portion of the consideration for the Closing Date Acquisition on the Effective Date, (ii) prepayments of principal and interest under the Subordinated Seller Notes after the Effective Date, provided that the conditions for such prepayment set forth in Section 5.10(a) shall have been met, and (iii) working capital or other general business purposes of the Borrower.

The Line of Credit will include an investment and borrowing sweep feature on the terms and conditions of a Line of Credit and Investment Sweep Rider (the “Sweep Rider”) to be executed and delivered by the Borrower to the Bank, in form and substance satisfactory to the Bank, the terms of which are hereby incorporated herein by reference. The Sweep Rider will remain in effect until such time (if any) as it is terminated in accordance with its terms.

1.2. Term Loan. One of the Loans governed by this Agreement is a term loan in the principal amount of $15,000,000.00 (the “Term Loan”). The proceeds of the Term Loan will be used to finance a portion of the consideration for the Closing Date Acquisition on the Effective Date.

1.4. Unused Fee. The Borrower will pay to the Bank an Unused Fee (as defined in the Line of Credit Note) in such amounts and at such times described in the Line of Credit Note.

2. Security. The security for repayment of the Obligations (as defined herein) shall include but not be limited to the collateral, guaranties and other documents heretofore, contemporaneously or hereafter executed and delivered to the Bank (the “Security Documents”), which shall secure repayment of the Loans and all other loans, advances, debts, liabilities, obligations, covenants and duties owing by the Borrower or the Guarantors to the Bank or to any other direct or indirect subsidiary of The PNC Financial Services Group, Inc. of any kind or nature, present or future (including any interest accruing thereon after maturity or after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding relating to Borrower or any Guarantor under the Loan Documents, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding), whether direct or indirect (including those acquired by assignment or participation), absolute or contingent, joint or several, due or to become due, now existing or hereafter arising, whether or not (i) evidenced by any note, guaranty or other instrument, (ii) arising under any agreement, instrument or document executed in connection with the Loan Documents, (iii) for the payment of money under the Loan Documents, (iv) arising by reason of an extension of credit, opening of a letter of credit, loan, equipment lease or guarantee under the Loan Documents, (v) under any interest or currency swap, future, option or other interest rate protection or similar agreement (but shall not include any Excluded Hedge Liabilities), (vi) under or by reason of any foreign currency transaction, forward, option or other similar transaction providing for the purchase of one currency in exchange for the sale of another currency, or in any other manner, (vii) liabilities to the Bank under any PNC-Provided Interest Rate Hedge, but shall not include the liabilities to other Persons under any other Interest Rate Hedge, or (viii) arising out of overdrafts on deposit or other accounts or out of electronic funds transfers (whether by wire transfer or through automated clearing houses or otherwise) or out of the return unpaid of, or other failure of the Bank to receive final payment for, any check, item, instrument, payment order or other deposit or credit to a deposit or other account, or out of the Bank’s non-receipt of or inability to collect funds or otherwise not being made whole in connection with depository or other similar arrangements; and any amendments, extensions, renewals and increases of or to any of the foregoing, and all reasonable costs and expenses of the Bank incurred in the documentation, negotiation, modification, enforcement, collection and otherwise in connection with any of the foregoing, including reasonable and documented out-of-pocket attorneys’ fees and expenses (hereinafter referred to collectively as the “Obligations”). Unless expressly provided to the contrary in documentation for any other loan or loans, it is the express intent of the Bank and the Borrower that all Obligations including those included in the Loans be cross-collateralized and cross-defaulted, such that collateral securing any of the Obligations shall secure repayment of all Obligations and a default under any Obligation shall be a default under all Obligations.

If the class action waiver is voided, found unenforceable, or limited with respect to any claim for which the Borrower seeks class-wide relief, then this Dispute Resolution section (except for this sentence) shall be null and void with respect to such claim, subject to the right to appeal the limitation or invalidation of the class action waiver. However, this Dispute Resolution section shall remain valid with respect to all other claims and Disputes. The parties acknowledge and agree that under no circumstances will a class action be arbitrated.

- 19 -
