ITEM 5.Interest In Securities Of The Issuer

(a)The Class B Stock of the Issuer is convertible into the Issuer’s Common Stock on a share for share basis. The aggregate number and percentage of securities to which this Schedule 13D relates is 4,776,074 shares of Common Stock and Class B Stock, representing 56.66% of 8,429,166 shares of Common Stock and Class B Stock of the Issuer. This number of shares outstanding is arrived at by taking the number of shares reported as being outstanding in the Issuer’s Form 10-QSB for the quarter ended June 30, 2007 disclosing 3,474,373 shares of the Issuer’s Common Stock outstanding, 647,715 shares of Class B outstanding or an aggregate of 4,122,088 shares of the Issuer’s Common Stock and Class B Stock outstanding and adding thereto 1,050 shares if the Reporting Person were to exercise two out-of-the-money director stock options held by him described below plus 909,090 shares issuable on exercise of the warrant issued April 20, 2006, 2,084,204 shares issuable on exercise of the warrant issued December 9, 2005, 761,614 shares acquirable on exercise of the five year warrant issued on September 30, 2004, 220,448 shares of the 551,121 shares acquirable in the next 60 days on exercise of a Stock Option issued January 26, 2005, 220,448 shares of the 551,121 shares acquirable in the next 60 days on exercise of a Stock Option granted November 22, 2005 and 110,224 shares of the 551,121 shares acquirable in the next 60 days on exercise of a Stock Option granted October 10, 2006; the balance of the shares acquirable under all such options and the Stock Option granted October 11, 2007 are not included in the calculation because they cannot be acquired in the next 60 days and only vest in 20% increments annually on the anniversary of grant. It should be noted except for the option granted October 10, 2006 at 20 cents a share, the exercise prices of all options and warrants are above the current market price of 25 cents a share.

* 9,053 of these shares are owned by the Reporting Person’s law firm. Pursuant to Rule 13d-3 an additional 909,090 shares are deemed owned on exercise of a warrant issued April 20, 2006, 2,084,204 shares are deemed owned on exercise of seven year warrant issued December 9, 2005, 761,614 shares are deemed owned on exercise of a five year warrant issued September 30, 2004, 1,050 shares are deemed owned based on options to purchase Common Stock which could be exercised by the Reporting Person as follows: 450 at $37.50 per share and 600 at $26.875 per share, respectively, expiring March 4, 2008 and October 20, 2009 respectively, 220,448 shares at 61 cents per share are deemed owned pursuant to an option for 551,121 shares expiring on January 25, 2015, 220,448 shares at 50 cents a share under an option granted November 22, 2005, and 110,224 shares at 20 cents a share under an option granted October 10, 2006. The total does not include an aggregate of 99,722 shares of Common Stock or 2.42% of the outstanding shares consisting of (i) 11,200 shares of Common Stock and 3,400 shares of Class B Stock owned by the Reporting Person’s wife, the beneficial ownership of which the Reporting Person disclaims, and (ii) an aggregate of 85,122 shares held as trustee for the benefit of two children of Charles P. Johnson, the Issuer’s former Chairman, of which the Reporting Person is the sole trustee, the beneficial ownership of which the Reporting Person disclaims. Such shares held as trustee consist of 78,683 shares of Class B Stock convertible into a like number of shares of Common Stock, 4,607 shares of Common Stock and an additional 1,832 shares of Common Stock if 20,000 shares of the Issuer’s 9% Cumulative Convertible Exchangeable Preferred Stock are converted into Common Stock at $136.50 per share. In calculating the aforesaid percentage of excluded shares, the amount of 1,832 shares acquirable on conversion is added to the shares of the Issuer outstanding at June 30, 2007. The 55.47% deemed owned is obtained by dividing the number of Common Stock shares deemed owned by the outstanding Common Stock increased by adding all shares acquirable on exercise or conversion in the next 60 days. The balance of the shares under the option expiring January 25, 2015, the stock option issued November 22, 2005, the option granted October 10, 2006 and all shares under the option granted on October 11, 2007 are not included because they may not be acquired in the next 60 days. It should be noted the exercise price of all options and warrants are above the current 25 cents per share market price of the Common Stock except the option granted October 10, 2006 at 20 cents per share.

(b)The Reporting Person has the sole power to vote or direct the vote, and sole power to dispose or to direct the disposition, of the shares of the Issuer reported for him for his own benefit, as well as to direct the vote and dispose of the shares held by him as trustee.

(c)Information with respect to all transactions in the shares of the Issuer which were effected during the past sixty days by the Reporting Person is set forth on Schedule I annexed hereto and incorporated herein by reference.

(d) Not applicable.

(e) Not applicable.

3. EXERCISE OF OPTION. The Optionee shall notify the Grantor by certified or registered mail addressed to its principal offices as to the number of shares which Optionee desires to purchase under the options herein granted, which notice shall be accompanied by payment by cash or check of the option price therefore as specified in paragraph 2 above. As soon as possible thereafter the Grantor shall, at its principal office, tender to Optionee certificates issued in the Optionee's name evidencing the shares purchased by the Optionee.

4. OPTION CONDITIONED ON CONTINUANCE AS A DIRECTOR.

(a)Each of the aforesaid options shall terminate and be void if the Optionee is not a director of the Grantor on the date in which such option is first exercisable.

(b)The Optionee shall have the right to purchase the shares as to which the options shall become exercisable only while Optionee is a director of the Grantor, except the options may be exercised to the extent that they are exercisable upon the effective date the Optionee ceases to be a director, at any time within three (3) months after the date of termination but in no event after the expiration of the last option herein contained.

5.DIVISIBILITY AND NON-ASSIGNABILITY OF THE OPTIONS.

(a)The Optionee may exercise the options herein granted from time to time during the periods of their respective effectiveness with respect to any whole number of shares included therein.

(b)Except as provided in the Grantor’s 2005 Stock and Bonus Plan for options granted under such Plan as if this Option was granted thereunder, the Optionee may not give, grant, sell, exchange, transfer legal title, pledge, assign or otherwise encumber or dispose of the options herein granted or any interest therein, otherwise than by will or the laws of descent and distribution, and these options, or any of them, shall be exercisable during Optionee's lifetime only by the Optionee.

(c)In the event of the Optionee's death (i) while a director of the Grantor or (ii) within three (3) months after the effective date that the Optionee ceases to be a director, or (iii) after the effective date that the Optionee ceases to be a director by reason of permanent and total disability, then (x) under (i), (ii) and (iii) above, all of the unexercised outstanding options granted under this Agreement shall automatically be accelerated and become fully vested and exercisable and (y) Optionee's estate, or any person who acquired the right to exercise such option by bequest or inheritance or by reason of the death of the Optionee, shall have the right at any time, but not after October 10, 2017, to exercise this option in full notwithstanding the vesting schedule in paragraph 1.

The Optionee shall not be considered permanently and totally disabled unless Optionee furnishes proof of the existence thereof in such form and manner and at such times as the Stock Option Committee of the Board of Directors administering the Plan may require.

The Optionee agrees that said committee's determination as to whether the Optionee is permanently and totally disabled shall be final and absolute, and not subject to question by the Optionee, a representative of the Optionee, or the Grantor.

6. STOCK AS INVESTMENT. By accepting this option the Optionee agrees for the Optionee, Optionee's heirs and legatees that, unless the shares have been registered under the Securities Act of 1933, as amended, any and all shares purchased hereunder shall be acquired for investment and not for distribution, and upon the issuance of any or all of the shares subject to the option granted hereunder, the Optionee, or Optionee's heirs or legatees receiving such shares, shall deliver to the Grantor a representation in writing that such shares are being acquired in good faith for investment and not for distribution. Grantor may place a "stop transfer" order with respect to such shares with its transfer agent and place an appropriate restrictive legend on the stock certificate unless such shares are registered.

7. RESTRICTION ON ISSUANCE OF SHARES. The Grantor shall not be required to issue or deliver any certificate for shares of its capital stock purchased upon the exercise of this option:

(b) unless the prior approval of such sale or issuance has been obtained from any state regulatory body having jurisdiction; or

(c) unless the shares with respect to which the option is being exercised have been registered under the Securities Act of 1933, as amended, or are exempt from registration.

8. ADJUSTMENT OF SHARES.

(a) If additional shares of common stock are issued by the Grantor pursuant to a stock split or stock dividend or distribution in excess of 5% in the aggregate in any one fiscal year of the Grantor, the number of shares of common stock then covered by each option granted herein shall be increased proportionately with no increase in the total purchase price of the shares then so covered. In the event that the shares of common stock of the Grantor are reduced at any time by a combination of shares, the number of shares of common stock then covered by each option granted herein shall be reduced proportionately with no reduction in the total price of the shares then so covered. If the Grantor shall be reorganized, consolidated or merged with another corporation, or if all or substantially all of the assets of the Grantor shall be sold or exchanged, the Optionee shall, at the time of issuance of the stock under such a corporate event, be entitled to receive upon the exercise of his option, the same number and kind of shares of stock or the same amount of property, cash or securities as he would have been entitled to receive upon the happening of any such corporate event as if he had been, immediately prior to such event, the holder of the number of shares covered by this option. No option adjustment shall be made for stock dividends, stock distributions or stock splits which are not in excess of 5% in any one fiscal year in the aggregate (even though the cumulated total of such stock dividends, distributions or splits over the life of an option may be in excess of 5% in the aggregate), cash dividends or the issuance to stockholders of the Company of rights to subscribe for additional common stock or other securities.

3

(b)Any adjustment in the number of shares shall apply proportionately to only the unexercised portion of an option granted hereunder. If fractions of a share would result from any such adjustment, the adjustment shall be revised to the next higher whole number of shares.

9.NO RIGHTS IN OPTION STOCK. Optionee shall have no rights as a stockholder in respect of shares as to which the option shall not have been exercised and payment made as herein provided and shall have no rights with respect to such shares not herein provided.

10.NO CONTRACT TO BE A DIRECTOR. Optionee further represents, covenants and warrants this Agreement does not constitute a contract to be a director of the Grantor or any of its subsidiaries or affiliates, nor does it give the Optionee any right to be a director of the Grantor, and Optionee’s continuance as a director is terminable as provided in the Grantor’s Certificate of Incorporation and by-laws.

11. BINDING EFFECT. Except as herein otherwise expressly provided, this Agreement shall be binding upon and inure to the benefit of the parties hereto, their legal representatives and assigns.

12. JURISDICTION OF DISPUTES. The appropriate Federal or State Courts of or located in the State in which the Grantor has its principal executive offices shall have exclusive jurisdiction of all disputes arising under this Agreement.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first above written.
