David L. Abrams.

Except as provided in the limited partnership agreement, Kandu Management has full and exclusive responsibility and discretion in the management, operation and control of Kandu Partners. These powers include the ability to cause Kandu Partners to dispose of and vote the shares of Common Stock owned by it. Kandu Partners was formed on May 10, 1999 and shall continue until the first to occur of (1) December 31, 2049, or (2) the dissolution of Kandu Partners pursuant to the express provisions of the limited partnership agreement.

During the past five years, none of the Reporting Persons has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to any civil proceedings of any judicial or administrative bodies of competent jurisdiction as a result of which he or it was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or State securities laws or finding any violation with respect to such laws.

Not applicable.

This Amendment is filed to reflect various changes in the facts set forth in previous filings by the Reporting Persons. The filing of this Amendment shall not be deemed an admission by the Reporting Persons that the changes reported herein are material within the meaning of Rule 13d-2(a) under the Securities Exchange Act of 1934, as amended.

Since prior filings, Mr. Abrams' beneficial ownership has changed because of (1) the vesting of options to purchase 10,000 shares of Common Stock and subsequent exercise of such options, (2) the receipt by Mr. Abrams of 2,682 shares of Common Stock as gifts from immediate family members who do not reside in Mr. Abrams' household and (3) the distribution to Mr. Abrams of 13,785 shares of Common Stock from Purple Heart Partners, LLLP, a Georgia limited liability limited partnership ("Purple Heart"), in connection with the liquidation of Purple Heart and the winding-up of its affairs. Mr. Abrams had previously reported that he could be deemed to share beneficial ownership of all 27,570 shares of Common Stock held by Purple Heart immediately prior to its liquidation. Also since prior filings, all of the Reporting Persons' holdings have been increased by stock dividends. Mr. Abrams was a director of the Issuer from 2000 to 2007.

Although no Reporting Person has any specific plan or proposal to acquire or dispose of the Common Stock, consistent with its investment purpose, each Reporting Person at any time and from time to time may acquire additional Common Stock or dispose of any or all of its Common Stock depending upon an ongoing evaluation of the investment in the Common Stock, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Persons and/or other investment considerations. Also, consistent with the investment purpose, the Reporting Persons may engage in communications with one or more shareholders of the Issuer, one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer and/or one or more representatives of the Issuer regarding the Issuer, including but not limited to its operations. The Reporting Persons may discuss ideas that, if effected, may result in any of the following: the acquisition by persons of additional Common Stock of the Issuer, an extraordinary corporate transaction involving the Issuer, and/or changes in the board of directors or management of the Issuer.

The Reporting Persons have publicly stated in a press release dated August 19, 2008 that they intend to vote against the proposed amendment to the Issuer's articles of incorporation at the Issuer's 2008 annual meeting of shareholders that would increase the number of authorized shares of its Common Stock from 5,000,000 shares to 10,000,000 shares. Although the Reporting Persons therefore could be deemed to hold shares for the purpose or effect of changing or influencing control of the Issuer, they do not concede that they hold shares for such purpose or effect.

Except to the extent the foregoing may be deemed a plan or proposal, none of the Reporting Persons has any plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. Each Reporting Person may, at any time and from time to time, review or reconsider its position and/or change its purpose and/or formulate plans or proposals with respect thereto.

* Based on the number of shares of Common Stock outstanding as of July 14, 2008 as reported in the Issuer's Preliminary Proxy Statement on Schedule 14A filed on July 21, 2008.

Kandu Management could be deemed to share with Kandu Partners and Mr. Abrams beneficial ownership of the 707,561 shares of Common Stock owned directly by Kandu Partners because of Kandu Management's management of Kandu Partners as described in Item 2. Mr. Abrams could be deemed to share beneficial ownership with Kandu Partners and Kandu Management of the 707,561 shares of Common Stock owned directly by Kandu Partners because of Mr. Abrams' offices as sole director and president of Kandu Management.

(c) None.

(d) None.

(e) Not applicable.

Except as described in this Amendment, the Reporting Persons are not a party to any contracts, arrangements, understandings or relationships (legal or otherwise) with any other person with respect to any securities of the Issuer, including finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this Amendment is true, complete and correct.
