ESCROW AGREEMENT This Escrow Agreement (the "Agreement") is made and entered into this 14th day of September, 2004, by and among Capital Growth Systems, Inc. a Florida corporation ("CGSI"), Frontrunner Representative, Inc., as the escrow agent (the "Representative") and each party named on the signature line below under "Creditor" (each a "Creditor" and collectively, the "Creditors"). RECITALS A. Pursuant to each of those certain Creditor Waiver and Consent Agreements, each dated August 6, 2004 (each, a "Creditor Agreement" and collectively the "Creditor Agreements"), by and among CGSI, Frontrunner Network Systems Corp., a Delaware corporation (the "Company") and each of the Creditors, an aggregate of 133,368 shares of common stock of CGSI (the "Escrowed Shares") are being delivered to the Representative for the benefit of the Creditors to secure the indemnification obligations of the Creditors under the Creditor Agreements. B. The parties hereto desire to have the Representative hold and release the Escrowed Shares and any proceeds thereof pursuant to the terms hereof. NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants and agreements hereinafter set forth, the parties hereto agree as follows: 1. Representative. The Representative hereby agrees to hold and release the Escrowed Shares and any proceeds thereof (collectively, the "Collateral") in accordance with the terms hereof. 2. Escrow Account. (a) Pursuant to and in accordance with Section 3 of the Creditor Agreements, and out of the shares of common stock of CGSI ("CGSI Common Stock") to be issued to the Creditors in connection with the Creditor Agreements, CGSI is delivering, for and on behalf of the Creditors, the following into escrow with the Representative: (i) the Escrowed Shares; and (ii) stock powers (duly executed in blank) covering the Escrowed Shares. The Representative hereby acknowledges receipt of the Escrowed Shares and stock powers. The Creditors hereby (i) authorize CGSI to deliver directly to the Representative all non-cash dividends and distributions made in respect of any Escrowed Shares (whether paid in shares of CGSI Common Stock, other securities or other property, in each case other than cash), all of which dividends and distributions shall be added to and become part of the Collateral, and (ii) agree to deliver to the Representative such additional stock powers and other instruments of transfer (duly executed in blank) as CGSI shall reasonably request from time to time in respect of all securities and other property (other than cash) deposited with the Representative from time to time pursuant to clause (i) of this sentence. (b) The Representative shall maintain a separate account for each of the Creditors (each such account, the "Creditor's Escrow Account"), including the number of Escrowed Shares held on such Creditor's behalf and any subsequent non-cash dividends or distributions deposited with the Representative with respect to such Creditor's Escrowed Shares. The initial number of Escrowed Shares held on behalf of each Creditor is set forth on Schedule A attached to this Agreement. The Collateral shall not be subject to any lien or attachment by any creditor of CGSI, the Representative or any of the Creditors. 3. Rights in Escrowed Shares. Except as provided herein, all legal and beneficial ownership rights to the Collateral shall remain with the Creditors during such time as the Collateral is held by the Representative, including, but not limited to, any right to vote or to receive distributions thereon. All communications, cash distributions and cash dividends paid or sent by CGSI with respect to the Collateral shall be paid or sent directly to the Creditors. 4. Procedures for Claims. Upon delivery by CGSI to the Representative of a Claim Notice (as defined in the Creditor Agreement) pursuant to Section 3(d) of the Creditor Agreements prior to the Termination Date (as defined herein), the Representative and CGSI shall promptly meet to resolve the Claim Notice. Pursuant to the Creditor Agreement, Representative shall have full legal right and authority to settle any claims on behalf of the Creditors and to release the Escrowed Shares in settlement of such claims. If Representative and CGSI do not reach a settlement within thirty-days of the date of the Claim Notice, CGSI shall have the right to bring suit against the Creditors to resolve such claim and pursue any other legal remedies it may have with respect to such claim. Upon delivery to Representative of (i) a written agreement signed by the Representative and CGSI, or (ii) a certified copy of a final judgment or decree binding on the Creditors, each of which fixes the amount of the Merger Agreement Losses (as defined in the Creditor Agreement) to which CGSI is entitled to be indemnified (the "Indemnifiable Damages"), the Representative shall deliver to CGSI that portion of the Collateral equal in value to the Indemnifiable Damages. For purposes of this Agreement, a share of CGSI Common Stock shall have a value of $1.35. In accordance with Section 3 of the Creditor Agreement, the Creditors shall share any Indemnifiable Damages in accordance with their Pro Rata Share (as defined in the Creditor Agreement), and the Representative shall make corresponding deductions of Collateral from each Creditor's Escrow Account. 5. Termination of Escrow. Upon the first anniversary of the date of this Agreement (the "Termination Date") the Representative shall release to each Creditor the Collateral in its Creditor Escrow Account, less each Creditor's Pro Rata Share of the amount of any unresolved claims as set forth in a Claim Notice that has been delivered prior to the Termination Date ("Pending Claims"). The Representative shall continue to hold the Collateral after the Termination Date until the Pending Claims are settled in accordance with Section 4 of this Agreement, and upon resolution of such Pending Claims, disburse the Collateral to the CGSI in the amount of the Indemnifiable Damages, if any, and any balance to the Creditors. 6. Representative Provisions. (a) The Creditors agree to indemnify and hold Representative harmless from all losses, costs, damages, expenses and reasonable attorneys' fees incurred by Representative arising from acts or omissions of Representative in the performance of or pursuant to this Agreement, except such acts or omissions as may be the result of 2 Representative's gross negligence or misconduct. Representative shall have no liability to the Creditors arising from acts or omissions of Representative pursuant to this Agreement except such acts or omissions as may be the result of the Representative's gross negligence or misconduct. (b) The Representative may rely upon any instrument in writing believed by it to be genuine, sufficient and properly presented. (c) The Representative may execute any of its duties under this Agreement by or through agents or employees. 7. Amendments.
