LCM and Shapiro disclaim beneficial ownership of the Stock except to the extent of their respective pecuniary interests therein. DAP is filing jointly with the other filers, but not as a member of a group, and expressly disclaims membership in a group. In addition, the filing of this Schedule 13D on behalf of DAP should not be construed as an admission that it is, and it disclaims that it is, the beneficial owner of any of the Stock covered by this Statement.

(b)

The business address of the Filers is
591 Redwood Highway, Suite 2345, Mill Valley, CA 94941.

Item 3. Source and Amount of Funds or Other Consideration

The source and amount of funds used in purchasing the Stock were as follows:

Purchaser	Source of Funds	Amount
LCM⁽¹⁾	Funds under Management	$2,229,188.91
DAP	WC	$1,940,868.20

⁽¹⁾ Includes funds of DAP

Item 4. Purpose of Transaction

As previously disclosed, the Filers ("Lawndale") and Sparton Corporation ("Sparton" or the "Company") entered into an agreement on September 17, 2008 (the "Agreement"), that provided, among other items, the appointment of two independent and highly experienced individuals nominated by Lawndale to Sparton’s board. The foregoing description of the Agreement is qualified in its entirety by reference to the full text of the Agreement, (a copy of which was attached as Exhibit B of Lawndale’s Schedule 13D, Amendment No. 15, and incorporated by reference to this filing). In an August 3, 2009, letter to Sparton’s Board (a copy of which was attached as Exhibit B of its Schedule 13D, Amendment No. 16, and incorporated by reference to this filing), Lawndale terminated the Agreement.

Over the past several years, Lawndale believes Sparton’s Board successfully implemented substantial operating and managerial improvements requested by Lawndale. In addition, Lawndale believes Sparton’s board has materially enhanced and improved its corporate governance and board composition as generally requested by Lawndale. Specific improvements implemented by Sparton’s Board included de-staggering and shrinking its board, adopting a majority vote requirement, improving compensation plans’ alignment with shareholders, and implementing say-on-pay votes on these plans earlier than required.

Lawndale believes that Sparton’s operational performance and stock price have benefited from both these operational and governance improvements.

Lawndale may from time to time take such actions as it deems necessary or appropriate to maximize its investment in the Company's shares. Such action(s) may include, but is not limited to, buying or selling the Company's Stock at its discretion, communicating with the Company's shareholders and/or others about actions that may be taken to improve the Company's financial situation or governance policies or practices, as well as such other actions as Lawndale, in its sole discretion, may find appropriate.

Lawndale incorporates by reference its activities and discussions disclosed in its prior Schedules 13D to the extent not inconsistent with the discussion herein.
