WHEREAS, the Smith Trust is a shareholder of Arthur H. Ltd. d/b/a International Software Products, a Virginia corporation (“ISP”);

WHEREAS, the Company, Hopley, the Smith Trust, Christopher M. Brittin, F. Gilmer Siler and ISP propose to enter into a Contribution Agreement, of even date herewith (the “Contribution Agreement”), pursuant to which the Company would acquire all of the issued and outstanding shares of capital stock of ISP in exchange for, among other things, shares of common stock, par value $.01 per share, of the Company (such common stock to be received by the Smith Trust as well as other securities issued with respect to the Company’s capital stock by means of share splits, combinations, dividends or other similar recapitalization events being referred to as the “Subject Shares”);

WHEREAS, as a condition to its willingness to enter in the Contribution Agreement, the Company has requested that the Smith Trust enter into this Agreement; and

WHEREAS, capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Shareholders Agreement;

NOW, THEREFORE, to induce the Company to enter into, and in consideration of entering into, the Contribution Agreement, and in consideration of the premises and the representations, warranties and agreements contained herein, the parties agree as follows:

1. Representations and Warranties of the Smith Trust. The Smith Trust hereby represents and warrants to the Company that (a) the Smith Trust has all requisite power and authority to enter into this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby and (b) this Agreement has been duly authorized, executed and delivered by the Smith Trust and constitutes a valid and binding obligation of the Smith Trust enforceable in accordance with its terms.

2. Covenants of the Smith Trust. Until the termination of this Agreement in accordance with Section 4 hereof, the Smith Trust agrees as follows:

(a) Voting of Subject Shares. At any meeting of shareholders of the Company or at any adjournment thereof or in any other circumstances upon which any Company shareholder’s vote, consent or other approval (including by written consent) is sought, the Smith Trust shall vote all of the Subject Shares then beneficially owned by it as directed by

Hopley. The Smith Trust shall not hereafter, unless and until this Agreement terminates pursuant to Section 4 hereof, purport to grant (other than through the irrevocable proxy granted in Section 2(b)) any proxy or power of attorney with respect to any of the Subject Shares, deposit any of the Subject Shares into a voting trust or enter into any agreement (other than this Agreement), arrangement or understanding with any person, directly or indirectly, to vote, grant any proxy or give instructions with respect to the voting of any of the Subject Shares. The Smith Trust further agrees not to commit or agree to take any action inconsistent with the foregoing.

(b) Proxy. The Smith Trust hereby grants to Hopley, as the Smith Trust’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of the Smith Trust, a proxy to vote, or to grant a consent or approval in respect of, all of the Subject Shares then beneficially owned by the Smith Trust as indicated in Section 2(a) above, and Hopley hereby accepts such proxy. The Smith Trust agrees that this proxy shall be irrevocable and coupled with an interest and may under no circumstances be revoked, agrees to take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy and hereby revokes any proxy previously granted by the Smith Trust with respect to any of the Subject Shares. Such irrevocable proxy is executed and intended to be irrevocable in accordance with the provisions of Section 14-2-722 of the Georgia Business Corporation Code.

(c) Transfer Restrictions. The Smith Trust agrees not to sell, transfer, pledge, encumber, assign or otherwise dispose of (including by gift) (collectively, “Transfer”), or enter into any contract, option or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of, any of the Subject Shares to any person unless (i) permitted by the Shareholders Agreement and (ii) the transferee agrees in writing (to the reasonable satisfaction of the Company) to be bound by all of the terms and conditions of this Agreement.

(d) Mandatory Sale of Subject Shares. In the event that Hopley sells or transfers her Transferee Shares for any reason including, without limitation, pursuant to the Shareholders Agreement or the Put Agreement, then the Smith Trust shall sell or transfer its pro rata portion of the Subject Shares on the same terms and conditions; provided, however, that the provisions of this Section 3(d) shall not apply to permitted transfers by Hopley pursuant to Section 2(e) of the Shareholders Agreement; and provided further, that the Smith Trust shall be entitled to exercise or decline the Buyback Right (as defined in the Shareholders Agreement) regardless of Hopley’s election with respect thereto.
