C.             In order to induce the Lenders to make the above-referenced loans and extensions of credit to the Borrower, and because of the direct benefit to the Existing Creditor of such New Indebtedness to the Borrower, the Existing Creditor has agreed to enter into this Agreement.

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

ARTICLE I

Priority of Liens

1.1 The Existing Creditor consents and agrees that it is hereby subordinating its security interest in and to the collateral described on Schedule A (the “Collateral”) to the security interest of the Lenders in and to the Collateral granted to the Lenders pursuant to the Security Agreement. All security interests now or hereafter acquired by the Lenders in the Collateral to secure the New Indebtedness shall at all times be prior and superior to any security interest or

other interest or claim now held or hereafter acquired by the Existing Creditor in the Collateral. The Agent, on behalf of the Lenders, consents and agrees that it is hereby subordinating the security interest of the Lenders in and to any property and assets of the Borrower other than the Collateral to the security interest of the Existing Creditor in and to such property and assets. All security interests now or hereafter acquired by the Existing Creditor in any property and assets of the Borrower other than the Collateral shall at all times be prior and superior to any security interest or other interest or claim now held or hereafter acquired by the Lenders therein. The Agent, on behalf of the Lenders, and the Existing Creditor acknowledge that the subordination evidenced hereby is a subordination of lien priority and not a subordination of the Existing Indebtedness and the New Indebtedness. The foregoing lien priorities shall be applicable irrespective of the time or order of attachment or perfection of any security interest or the time or order of filing of any financing statements or other documents, or any statutes, rules or law, or court decisions to the contrary.

1.2 This Agreement shall constitute a continuing agreement of lien subordination, during which time the Agent, on behalf of the Lenders, and the Existing Creditor each agree that the other may at any time, and from time to time, without the consent of the other party and without notice to the other party, renew or extend any of the indebtedness, liabilities or obligations owing to it from the Borrower (the “Secured Obligations”) or that of any other person or entity at any time directly or indirectly liable for the payment of any Secured Obligations, accept partial payments of the Secured Obligations, settle, release (by operation of law or otherwise), compound, compromise, collect or liquidate any of the Secured Obligations, refrain from making any loans or advances to the Borrower, or change, alter or vary the interest charge on the Secured Obligations.

1.3 The Existing Creditor shall not collect, take possession of, foreclose upon, or exercise any other rights or remedies with respect to the Collateral, judicially or non judicially, or attempt to do any of the foregoing, without the prior written consent of the Agent, on behalf of the Lenders, which shall be a matter of the Agent’s sole discretion; provided that, notwithstanding the foregoing, the Existing Creditor, without the consent of or notice to the Lenders, may (a) in any insolvency or liquidation proceeding, assert its claims with respect to the Secured Obligations owing to it (including, without limitation, filing any proof of claim) and vote such claims, (b) take any action to preserve or protect the validity and enforceability of its security interests in the Collateral so long as such action is not inconsistent with this Agreement, (c) file any necessary responsive or defensive pleadings in opposition to any pleading objecting to or seeking disallowance of the Existing Creditor’s claims or otherwise make any agreements or file any motions pertaining to the Secured Obligations owing to it, in each case to the extent not inconsistent with the terms of this Agreement, (d) exercise rights and remedies available to an unsecured creditor with respect to the Collateral, and (e) exercise any rights or remedies with respect to the property and assets of the Borrower other than the Collateral. The Lenders shall not collect, take possession of, foreclose upon, or exercise any other rights or remedies with respect to the property and assets of the Borrower other than the Collateral, judicially or non-judicially, or attempt to do any of the foregoing, without the prior written consent of the Existing Creditor, which shall be a matter of the Existing Creditor’s sole discretion; provided that, notwithstanding the foregoing, the Lenders, without the consent of or notice to the Existing Creditor, may (a) in any insolvency or liquidation proceeding, assert their claims with respect to

the Secured Obligations owing to them (including, without limitation, filing any proof of claim) and vote such claims, (b) take any action to preserve or protect the validity and enforceability of their security interests in the Collateral so long as such action is not inconsistent with this Agreement, (c) file any necessary responsive or defensive pleadings in opposition to any pleading objecting to or seeking disallowance of the Lenders’ claims or otherwise make any agreements or file any motions pertaining to the Secured Obligations owing to them, in each case to the extent not inconsistent with the terms of this Agreement, (d) exercise rights and remedies available to an unsecured creditor with respect to the property and assets of the Borrower other than the Collateral, and (e) exercise any rights or remedies with respect to the Collateral.

1.4 The Agent, on behalf of the Lenders, and the Existing Creditor each agree, upon the request of the other party, to execute all such documents and instruments and take all such actions as the other party shall reasonably request in order to carry out the purposes of this Agreement; provided, however, that this Agreement shall remain fully effective notwithstanding any failure to execute any additional documents or instruments. The Existing Creditor represents and warrants that it has not heretofore transferred or assigned any Financing Statement naming the Borrower as debtor and it as secured party and that it will not transfer or assign any such Financing Statement in the future without first delivering a copy of this Agreement to the proposed transferee or assignee, which shall agree to be bound by the terms of this Agreement. The Agent, on behalf of the Lenders, represents and warrants that the Lenders will not transfer or assign any Financing Statement naming the Borrower as debtor and any Lender as secured party, or its rights under this Agreement, in the future without first delivering a copy of this Agreement to the proposed transferee or assignee, which shall agree to be bound by the terms of this Agreement.

1.5 The Agent, on behalf of the Lenders, agrees that if the Agent, any Lender or any affiliate or related party of the Agent or any Lender exercises remedies against the Collateral and takes possession of, operates, or obtains title to the Collateral, then the network and the network equipment included in the Collateral shall continue during such possession, operation and title to be configured to direct any person or entity accessing the network to http://www.myconvoy.com or any similar successor uniform resource locator (url) or domain name. Notwithstanding the foregoing, if the Collateral is transferred to a person or entity other than (i) the Agent, (ii) any Lender, (iii) any affiliate or related party of the Agent or (iv) any affiliate or related party of any Lender, then the provisions of this Lien Subordination Agreement shall not apply to such purchaser. The Agent, on behalf of the Lenders, acknowledges and agrees that the Existing Creditor has relied upon the provisions of this section in entering into this Agreement.

ARTICLE II

Events of Default; Borrower’s Consent

2.1 Any default or event of default by the Borrower under any present or future instrument or agreement between the Borrower and the Lenders shall constitute an immediate default and event of default under all present and future instruments and agreements between the Borrower and the Existing Creditor.

constitute an immediate default and event of default under all present and future instruments and agreements between the Borrower and the Lenders. In addition, an event of default shall be deemed to have occurred under all present and future instruments and agreements between the Borrower and the Existing Creditor and between the Borrower and the Lenders if (a) any person or group of persons shall acquire beneficial ownership of 40% or more of the issued and outstanding shares of capital stock of the Company having the right to vote for the election of directors of the Company; (b) individuals who constitute the board of directors of the Company (together with any new directors whose election by the board of directors of the Company or whose nomination for election by the stockholders of the Company was approved by a vote of at least two-thirds of the directors then still in office who either were directors on the date hereof or whose election or nomination for election was previously so approved) cease for any reason other than death or disability to constitute a majority of the directors then in office; or (c) Mark L. Grannell shall cease to be the acting chief executive officer of the Company.
