Section 2. Credit Extensions.

          2.1. Credit Extensions – Revolving Facility. Subject to and upon the terms and conditions of this Agreement and provided that no Event of Default has occurred and is continuing, at any time and from time to time from the Effective Date through the Revolving Maturity Date, Bank will make available to Borrower a Revolving Facility under which Borrower may request and Bank agrees to make advances (“Advance” or “Advances”) to Borrower to finance its and its Subsidiaries’ Accounts and to be used as working capital, to finance the acquisition of the outstanding capital stock of ORC, to satisfy the remaining indebtedness of ORC under ORC’s existing line of credit with Wachovia Bank, N.A., and to finance the acquisition of the outstanding capital stock of Zegato – and not for any other purpose. The aggregate amount of outstanding Advances shall not exceed at any time the lesser of (A) the Committed Revolving Line or (B) the Borrowing Base. If no Event of Default has occurred and is continuing, amounts borrowed under the Revolving Facility may be repaid and reborrowed at any time prior to the Revolving Maturity Date.

          2.2. Credit Extensions – Disbursements. Unless Bank consents to a different procedure or process, or makes available to Borrower a different procedure or process, whenever Borrower desires an Advance, Borrower shall notify Bank (which notice shall be irrevocable) by facsimile transmission or telephone no later than 10:00 a.m. eastern time, on the Business Day on which Borrower desires the Advance to be made. Each notification by facsimile transmission shall include the information requested on Bank’s Loan Payment/Advance Request Form and shall be signed by a Responsible Officer or a designee thereof. Each notification by telephone shall include the information requested on Bank’s Loan Payment/Advance Request Form and each notification by telephone shall be followed within one Business Day by a facsimile transmission which meets the criteria regarding a facsimile transmission. Bank shall be entitled to rely on any telephonic notice given by a person who Bank reasonably believes to be a Responsible Officer or a designee thereof. Bank shall not have any liability to Borrower or any other Person for its failure to make an Advance on the date requested by Borrower, unless such failure is the result of willful misconduct or gross negligence of Bank; and if Bank’s failure is a result of willful misconduct or gross negligence, its liability shall be limited to actual damages only – Bank shall not be liable for any indirect, speculative, consequential or punitive damages or losses. If Borrower maintains its operating deposit account with Bank, Bank will credit the amount of the Advance to such account, and the Borrower agrees that the Bank may debit any account maintained by the Borrower with the Bank for payments (including, but not limited to amounts in excess of the Borrowing Base, principal payments, interest and administrative fees) due to the Bank under the Loan Documents. If Borrower does not maintain its operating deposit account with Bank, Bank will issue to Borrower for deposit in its operating deposit account a bank check or other negotiable instrument drawn on Bank in the amount of the Advance.

          2.3. Overadvances. If, at any time, the aggregate amount of the outstanding principal under any Credit Extension exceeds the maximum amount that is permitted to be outstanding at any one time, as provided in this Section 2., the Borrower shall immediately pay to Bank, in cash, the amount of such excess. The Borrower agrees that if the outstanding Advances exceed the Borrowing Base at any time the Borrower shall prepay the Advances immediately in an amount equal to the excess. Further, if the Borrower fails to provide the Bank with a Borrowing Base Certificate when required by this Agreement, the Borrower agrees that the Bank may deem the Borrowing Base to be zero for the purposes hereof.

          2.4. Charging of Payments. Bank may, at its option, set-off and apply to the Obligations which are then due and payable and otherwise exercise its rights of recoupment as to any and all (i) balances and deposits of Borrower held by Bank, (ii) indebtedness and other obligations at any time owing to or for the credit or the account of Borrower by Bank and by any of Bank’s Affiliates.

          2.5. Fees. In addition to the other fees, charges, costs and expenses required to be paid by Borrower under this Agreement and the other Loan Documents, Borrower shall pay to Bank the fees, charges, costs and expenses set forth in this Section 2.5.

               2.5.1. Facility Fee. Borrower shall pay to Bank a nonrefundable facility fee of $25,000 for the commitment made in Section 2.1, (a) $12,500 of which shall be due and payable on or before the Effective Date, and (b) $12,500 of which shall become due and payable at such time as the Committed Revolving Line shall become $5,000,000. Bank may, at its option, set-off the amount due from the Borrower under the foregoing clause (b) against the balances and deposits of Borrower held by Bank.

               2.5.2. Bank Expenses. On the Closing Date, Borrower shall pay to Bank all Bank Expenses incurred through the Closing Date up to a maximum amount of $40,000, and shall pay, as and when demand is so made by Bank to Borrower, all Bank Expenses incurred relating to completion, after the Closing Date, of matters related to closing of this Agreement. Borrower shall be responsible for its own fees and expenses, including its legal fees.

          2.6. Documentary and Intangible Taxes; Additional Costs. To the extent not prohibited by law and notwithstanding who is liable for payment of the taxes and fees, Borrower shall pay, on Bank’s demand, all intangible personal property taxes, documentary stamp taxes, excise taxes and other similar taxes assessed, charged and required to be paid in connection with the Credit Extensions and any extension, renewal and modification thereof, or assessed, charged and required to be paid in connection with this Agreement, any of the other Loan Documents and any extension, renewal and modification of any of the foregoing.

2

obligation to make Credit Extensions under this Agreement. Notwithstanding the foregoing, Bank shall have the right to limit, declare a moratorium on or terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance of an Event of Default; and such action by Bank shall not constitute a termination of this Agreement, shall not constitute a termination of Borrower’s obligations under this Agreement and the other Loan Documents and shall not adversely affect or impair Bank’s security interests in the Collateral.

               8.2.1. Acceleration of Obligations. Bank may, at its option, accelerate and declare immediately due and payable the Obligations, as well as any of and all of the other indebtedness and obligations owing under this Agreement and the other Loan Documents that are not already due hereunder and that are not already due thereunder. If there is more than one Obligation, Bank may accelerate and declare immediately due and payable all of the Obligations, or Bank may from time to time and at any number of times after the occurrence of an Event of Default, accelerate and declare immediately due and payable any one or more of the Obligations as Bank in its discretion elects to accelerate.

               8.2.2. Protection of Collateral. Bank may make such payments and do or cause to be done such acts as Bank considers necessary or advisable to protect the Collateral and to preserve, protect, prefect or continue the perfection of its security interest in the Collateral, including managing all or any part or parts of the Collateral.

Borrower authorizes Bank and its representatives to enter the premises where the Collateral is

12

located, to do, among other things Bank deems necessary or advisable, the following: (i) take and maintain possession of the Collateral, or any part or parts of it, (ii) pay, purchase, contest or compromise any encumbrance, charge or lien which in Bank’s determination appears to be prior or superior to its security interest, and (iii) pay all costs and expenses incurred in connection with any of the foregoing.

Bank is hereby irrevocably granted a license or other right, pursuant to the provisions of this Section 8.2, to use, without charge, Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, advertising matter and any property of a similar nature, together with the right of access to all tangible or electronic media in which any of the foregoing may be recorded or stored, in completing production of, management of, advertising for sale and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section 8.2, Borrower’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit. Borrower hereby agrees: (i) that ten (10) days notice of any intended sale or disposition of any Collateral is commercially reasonable; (ii) that a shorter period of notice will be commercially reasonable if Bank, in its opinion, deems it necessary to move more expeditiously with disposition of the Collateral or any part thereof; and (iii) that the foregoing shall not require a notice if no notice is required under the Code.

               8.2.4. Discontinuance of Proceedings; Position of Parties Restored. If Bank shall have proceeded to enforce any right or remedy under the Loan Documents by foreclosure, entry, or otherwise and such proceedings shall have been discontinued or abandoned for any reason, or such proceedings shall have resulted in a final determination adverse to Bank, then and in every such case Borrower and Bank shall be restored to their former positions and rights hereunder, and all rights, powers and remedies of Bank shall continue as if no such proceedings had occurred or had been taken.

          8.3. Demand Obligations. Notwithstanding anything else in this Agreement to the contrary, if any of the Obligations are payable on demand by Bank, then, in such event, there are no conditions precedent to Bank’s right to demand payment of such Obligations, in whole or in part, at any time and from time to time, without prior notice, until the entire unpaid balance outstanding under such Obligations, including principal, interest, fees, premiums, charges and costs and expenses are paid in full. And, there are no conditions precedent to Bank exercising any of and all of its other rights and remedies at such time or times as it deems necessary or appropriate to recover full payment of the Obligations, including the exercise of any of and all of its rights and remedies set forth in Section 8.2 above, the exercise of any of and all of its other rights and remedies granted to it under the Loan Documents and the exercise of any of and all of its rights and remedies at law and in equity

a perceivable form; that a record of any of the Loan Documents in a non-tangible medium which is retrievable in a perceivable form shall be the agreement of Borrower to the same extent as if such Loan Document was in its original, inscribed tangible medium and such a record shall be binding on and enforceable against Borrower.

          9.3. Credit Investigations; Sharing of Information. Bank is irrevocably authorized by Borrower to make or have made such credit investigations as it deems appropriate to evaluate Borrower’s credit or financial standing, and Borrower authorizes Bank to share with consumer reporting agencies and creditors its experiences with Borrower.

          9.4. Bank Expenses. Notwithstanding anything in this Agreement or any of the other Loan Documents to the contrary, Bank may at any time or times during the term of this Agreement make such payments and do or cause to be done such acts as Bank considers necessary or advisable to protect the Collateral and to preserve, protect, perfect or continue the perfection of its security interest in the Collateral or any part or parts thereof.

Bank’s rights and remedies under this Agreement, the Other Loan Documents and all other agreements shall be cumulative and may be exercised successively, concurrently, alternatively and in any other order and at such time or times as Bank elects in its discretion. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law and in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given.

          9.7. Jurisdiction; Waiver of Jury Trial. This Agreement and the other Loan Documents shall be governed by and construed in accordance with the substantive laws of the Commonwealth of Virginia, excluding, however, the conflict of law and choice of law provisions thereof.

Borrower waives and will not assert against any transferee or assignee of Bank any claims, defenses, set-offs or rights of recoupment which Borrower could assert against Bank, except defenses which Borrower cannot waive.

Unless otherwise provided in this Agreement, all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in writing and (except for financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by a recognized overnight delivery service, or by certified mail, postage prepaid, return receipt requested, or by facsimile to Borrower or to Bank, as the case may be, at their respective addresses as set forth on the signature page of this Agreement. The parties may change the address at which they are to receive notices hereunder by notice in writing in the foregoing manner given to the other.

          9.10. Amendments in Writing; Integration. Subject to the exercise by Bank of its rights and remedies as set forth in this Agreement and without limiting any of such rights and remedies, this Agreement may not be modified, amended, waived, extended, changed, discharged and terminated orally or by any act or failure to act on

14

the part of Borrower or Bank, but only by an agreement in writing signed by the party against whom enforcement of any modification, amendment, waiver, extension, change, discharge and termination is sought.
