Item 2.

Identity and Background

Item 2 of the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 and Amendment No. 5 are hereby amended and restated as follows:

This statement is being jointly filed by each of the following persons pursuant to Rule 13d-1(k) promulgated by the Securities and Exchange Commission pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”):

(1)

Koski Family Limited Partnership (“KFLP”), a Texas partnership.

(2)

Christine L. Koski, the managing general partner of KFLP and a Director of the Issuer.

(3)

Robert C. Koski, a general partner of KFLP and a Director of the Issuer.

(4)

Beverly L. Koski, as sole shareholder of Koski Management Inc., a general partner of KFLP.

(5)

Thomas L. Koski, a general partner of KFLP.

KFLP is a Texas -based private family partnership principally engaged in the business of investing and managing its own private equity investments.

The business address for KFLP is 3525 Turtle Creek Boulevard, Unit 19-B, Dallas, Texas 75219.

Each of the individuals set forth in clauses (2) through (5) are United States citizens. The business address for each is c/o Koski Family Limited Partnership, 3525 Turtle Creek Boulevard, Unit 19-B, Dallas, Texas 75219.

KFLP and the individuals listed in clauses (2) through (5) above (collectively, the “Reporting Persons”) may constitute a “group” for purposes of Rule 13d-5 under the Exchange Act with respect to their beneficial ownership of the Common Stock and are collectively referred to as the “Reporting Group.” The Reporting Group expressly disclaims that they have agreed to act as a group other than as described in this statement. The Reporting Persons have entered into a Joint Filing Agreement, a copy of which was filed with the Original Schedule 13D and incorporated herein by reference. Information with respect to each Reporting Person is given solely by such Reporting Person, and no Reporting Person assumes responsibility for the accuracy or completeness of the information furnished by another Reporting Person. This report on Schedule 13D constitutes an amendment to the original report of the Reporting Group.

During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person 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.

Item 3.

Source and Amount of Funds or Other Consideration

The Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 and Amendment No, 5 are supplemented and amended by the information below.

Based upon the Company’s Form 8-K filed on August 2, 2012, on July 31, 2012, the Company closed on a private placement wherein the Company entered into a Stock Purchase Agreement with certain accredited investors pursuant to which the Company: (i) sold to the Purchasers an aggregate of 8,666,665 shares of the Company’s Common Stock at a price per share of $1.50 for aggregate gross proceeds of approximately $13,000,000 (the “Offering”).

The terms of that certain Loan Agreement (“Loan Agreement”) between the Company and the KFLP which was entered into on March 23, 2012, provided for the automatic conversion of the secured debt represented by the Loan Agreement at the time of a “qualified financing” defined as financing by the Company raising an amount of no less than $5.0 million on the same terms as such financing. Because the Offering constituted a “qualified financing” under the terms of the Company’s Loan Agreement with the KFLP, the Company’s secured debt in the principal amount of $2.5 million, together, with accrued but unpaid interest thereon, due to the KFLP was automatically converted contemporaneously with the closing of the Offering into 1,692,123 shares of common stock issued to the KFLP at the same price of $1.50 per share paid by the Purchasers in the Offering.

This Amendment is also being filed to report the additional changes in beneficial ownership resulting from the issuance by the Company of common stock under the Company’s 2002 Amended and Restated Stock Incentive Plan, to officers and non-employee directors for previously disclosed performance-based objectives under long term incentive programs (“LTIPs”) that were triggered by the Offering. On August 6, 2012, the Company issued an aggregate of 278,713 shares under the LTIPs for executive officers participants and the non-employee directors of which non-employee directors Christine Koski and Robert Koski each were issued 30,000 shares.

This amendment is being filed to reflect the impact on the Reporting Persons beneficial ownership of the Company’s share issuances to (i) the Purchasers under the Offering, (ii) the KFLP for the conversion of its outstanding secured indebtedness, and (iii) resulting from the performance based stock awards described above.

Item 4.

Purpose of Transaction

Item 4 of the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 and Amendment No. 5 are supplemented and amended by the information below.

The information in Item 3 of this Amendment No. 5 is incorporated herein by reference.

Except as otherwise described in this Schedule 13D, none of the Reporting Persons currently has any plans or proposals that relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the Board except as may be required for the Company to comply with exchange listing requirements with respect to the number of independent directors; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer’s business or corporate structure; (g) any changes in the Issuer’s charter or by-laws or other actions which may impede the acquisition or control of the Issuer by any person; (h) causing a class of securities of the Issuer to be delisted from a national securities exchange or cease to be authorized to be quoted in an interdealer quotation system of a registered national securities association; (i) causing a class of equity securities of the Issuer to become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934; or (j) any action similar to those enumerated above.
