Stockholders’ Equity

 
Preferred Stock

In 1996, our Board of Directors authorized the issuance of 1,000,000 shares of preferred stock with a par value of $0.01.  As of June 30, 2011, 20,000 shares of preferred stock have been designated as Series A Junior Participating Preferred Stock, none of which are issued and outstanding, 313,960 shares of preferred stock have been designated as Series A Convertible Preferred Stock, par value $0.01 per share (“Series A Convertible Preferred Stock”), of which 261,135 shares are issued and outstanding, 279,256 shares of preferred stock have been designated as Series B Convertible Preferred Stock, par value $0.01 per share (“Series B Convertible Preferred Stock”), of which 84,176 shares are issued and outstanding and 303,125 shares of preferred stock have been designated as Series C Convertible Preferred Stock, par value $0.01 per share (“Series C Convertible Preferred Stock”), of which 77,087 shares are issued and outstanding.

Series A Convertible Preferred Stock

On February 12, 2009, we completed a private placement, pursuant to which we sold an aggregate of 156,980 units (the “Series A Units”) for a purchase price of $11.50 per unit (the “Series A Purchase Price”), resulting in gross proceeds to us of $1,805,270 (the “Series A Private Placement”).  Each Series A Unit consisted of  (i) one share of Series A Convertible Preferred Stock convertible into 10 shares of our common stock, (ii) a warrant to purchase one share of Series A Convertible Preferred Stock at an exercise price equal to $12.50 per share, with a term expiring 15 months after the date of closing (“15-Month Series A Preferred Stock Warrant”); and (iii) a warrant to purchase 10 shares of common stock at an exercise price equal to $2.00 per share, with a term expiring 30 months after the date of closing (the “30-Month Common Stock Warrants”).  We did not pay any placement fees associated with this transaction but the expenses related to the offering totaled approximately $233,000.  We have offered each holder of the 30-Month Common Stock Warrants a one-year extension of the life of the warrant to August 11, 2012.  See Note 6.

The proceeds from the sale of each Series A Unit was allocated between the Series A Convertible Preferred Stock, the 15-Month Series A Preferred Stock Warrant and the 30-Month Common Stock Warrant based on the relative estimated fair value of each security.  The estimated fair value of the warrants was determined using the Black-Scholes formula, resulting in an allocation of the gross proceeds of $882,253 to the total warrants issued.  The allocation of the gross proceeds to the Series A Convertible Preferred Stock was $923,017.  In accordance with the provisions of FASB ASC 470-20, Debt with Conversion and Other Options , an additional adjustment between Additional Paid in Capital and Accumulated Deficit of $489,803 was recorded to reflect an implicit non-cash dividend related to the allocation of proceeds between the stock and warrants issued.  The $489,803 represents the value of the adjustment to additional paid in capital related to the beneficial conversion feature of the Series A Convertible Preferred Stock.  The value adjustment was calculated by subtracting the fair market value of the underlying common stock on February 12, 2009 issuable upon conversion of the Series A Convertible Preferred Stock from the fair market value of the Series A Convertible Preferred Stock as determined when the Company performed a fair market value allocation of the proceeds to the Series A Convertible Preferred Stock and warrants.

Each share of Series A Convertible Preferred Stock receives a cumulative dividend at the rate of 5% per annum of the Series A Purchase Price, payable semi-annually on June 30 and December 31, commencing on June 30, 2009 (with the first payment being pro-rated based on the number of days occurring between the date of issuance and June 30, 2009).  Dividends may be paid in cash or in shares of common stock at our option, subject to certain conditions.  The shares of Series A Convertible Preferred Stock also are entitled to a liquidation preference, such that in the event of any voluntary or involuntary liquidation, dissolution or winding up of our Company, the holders of Series A Convertible Preferred Stock will be paid out of the assets of the Company available for distribution to our stockholders before any payment shall be paid to the holders of common stock, an amount per share equal to the Series A Purchase Price, plus accrued and unpaid dividends.  The Series A Convertible Preferred Stock (as described below) will be treated on an equivalent basis with respect to payments made in connection with a liquidation.  The Board approved the method of payment in the form of common stock for each of the dividend payment dates through June 30, 2011.

Each share of Series A Convertible Preferred Stock is convertible into 10 shares of common stock at any time at the option of the holder, subject to adjustment for stock splits, stock dividends, recapitalizations and similar transactions (the “Series A Conversion Ratio”). Unless waived under certain circumstances by the holder of Series A Convertible Preferred Stock, such holder’s shares of Series A Convertible Preferred Stock may not be converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.  Each share of Series A Convertible Preferred Stock will automatically be converted into shares of common stock at the Series A Conversion Ratio then in effect:  (i) if, after 12 months from the closing of the Series A Private Placement, the common stock trades on the Nasdaq Capital Market (or other primary trading market or exchange on which the common stock is then traded) at a price equal to $4.00 for 20 out of 30 consecutive trading days with average daily trading volume of at least 10,000 shares or (ii) upon a registered public offering by the Company at a per share price equal to $2.30 with aggregate gross proceeds to the Company of not less than $10 million.  

The holders of Series A Convertible Preferred Stock are not entitled to vote on any matters presented to the stockholders of the Company for their action or consideration at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of meeting), except that the holders of Series A Convertible Preferred Stock may vote separately as a class on any matters that would amend, alter or repeal any provision of our Restated Articles of Organization, as amended, in a manner that adversely affects the powers, preferences or rights of the Series A Convertible Preferred Stock and such holders may also vote on any matters required by law.

At any time after February 11, 2014, upon 30 days written notice, we have the right to redeem the outstanding shares of Series A Convertible Preferred Stock at a price equal to the Series A Purchase Price, plus all accrued and unpaid dividends thereon.  The redemption price may be paid in two annual installments.

15-Month Series A Preferred Stock Warrants and 30-Month Common Stock Warrants
Subject to the terms and conditions of the applicable warrants, the Company had the right to call for cancellation the 15-Month Series A Preferred Stock Warrants if the volume weighted average price of our common stock on the Nasdaq Capital Market (or other primary trading market or exchange on which our common stock is then traded) equaled or exceeded $1.75 for either (i) 10 consecutive trading days or (ii) 15 out of 25 consecutive trading days.  Pursuant to these provisions, on March 30, 2010, the Company called all of the 15-Month Series A Preferred Stock Warrants resulting in the issuance of 104,155 shares of Series A Convertible Preferred Stock.

The 15-Month Series A Preferred Stock Warrants had an exercise price equal to $12.50 per share, with a term expiring on May 12, 2010.  Each of the 15-Month Series A Preferred Stock Warrants were exercised in connection with the warrant call and, therefore, there are no longer any 15-Month Series A Preferred Stock Warrants outstanding.  The 30-Month Common Stock Warrants have an exercise price equal to $2.00 per share, with a term expiring on August 12, 2011.  Unless waived under certain circumstances by the holder of the 30-Month Common Stock Warrant, such holder’s 30-Month Common Stock Warrants may not be exercised if upon such exercise the holder’s beneficial ownership would exceed certain thresholds.  Each of the 15-Month Series A Preferred Stock Warrants permitted, and each of the 30-Month Common Stock Warrants permit the holder to conduct a “cashless exercise” at any time the holder of the warrant is an “affiliate” as defined in the applicable Securities Purchase Agreement of the Company.   

The warrant exercise price and/or number of shares issuable upon exercise of the applicable warrant are subject to adjustment for stock dividends, stock splits or similar capital reorganizations, as set forth in the warrants.  As a result of the issuance of Common Stock in connection with dividends paid on the Series A Preferred Stock and the Series B Preferred Stock, the exercise price of the 30-Month Common Stock Warrants has been adjusted from $2.00 to $1.74 (the “New Exercise Price”) to prevent dilution.  The number of shares for which the 30-Month Common Stock Warrants are exercisable is equal to the original per share exercise price of the Warrant, prior to any adjustment, divided by the New Exercise Price, multiplied by the original number of Warrant Shares.

Subject to the terms and conditions of the 30-Month Common Stock Warrant, the Company has the right to call for cancellation the 30-Month Common Stock Warrant if the volume weighted average price for our common stock on the Nasdaq Capital Market (or other primary trading market or exchange on which our common stock is then traded) equals or exceeds $2.80 for either (i) 10 consecutive trading days or (ii) 15 out of 25 consecutive trading days.

The warrants granted in connection with the Series A Units were valued based on a Black-Scholes pricing model at the date of the grant.  The 15-Month Series A Preferred Stock Warrants and 30-Month Common Stock Warrants were granted with an exercise price of $1.25 per share of Series A Convertible Preferred Stock and $2.00 per share of common stock, respectively.  The 15-Month Series A Preferred Stock Warrants and 30-Month Common Stock Warrants vested immediately.  The relative fair value of the warrants was calculated to be $882,253 and was recorded to stockholders’ equity in the first quarter of 2009.  The assumptions for the Black-Scholes pricing model are represented in the table below with the 15-month Series A Preferred Stock Warrants being reflected on a per share common stock equivalent basis.

Series B Convertible Preferred Stock

On November 18, 2009, we sold an aggregate of 62,039 units (the “Series B Units”) for a purchase price of $18.80 per unit (the “Series B Purchase Price”), resulting in gross proceeds to us of $1,166,333.  This was the first tranche of a $2.5 million private placement.  The second tranche closed on March 18, 2010 for the sale of 26,672 Series B Units with gross proceeds of $501,434 (collectively the two tranches are referred to as the “Series B Private Placement”).  Each Series B Unit consists of (i) one share of Series B Convertible Preferred Stock convertible into 10 shares of our common stock and (ii) a warrant to purchase one share of Series B Convertible Preferred Stock at an exercise price equal to $23.80 per share for warrants issued in November 2009 and at an exercise price of $28.80 for warrants issued in March 2010, in each case with a term expiring on August 11, 2011 (the “Series B Warrant”).  We have offered each holder of the Series B Warrant a one-year extension of the life of the warrant to August 11, 2012, but the warrant would be exercisable for Common Stock.  See Note 6.

In connection with the Series B Private Placements, we paid a finder’s fee of $100,478, plus warrants to purchase 5,344 shares of Series B Convertible Preferred Stock at $28.80 per share, expiring August 11, 2012.

The proceeds from the sale of each Series B Unit were allocated between the Series B Convertible Preferred Stock and the Series B Warrant based on the relative estimated fair value of each security.  The estimated fair value of the Series B Warrants was determined using the Black-Scholes formula, resulting in an allocation of the gross proceeds of $592,685 to the total warrants issued for both tranches.  The allocation of the gross proceeds to the Series B Convertible Preferred Stock was $1,075,083 for both tranches.  In accordance with the provisions of FASB ASC 470-20, Debt with Conversion and Other Options , an additional adjustment between Additional Paid in Capital and Accumulated Deficit of $294,838 was recorded to reflect an implicit non-cash dividend related to the allocation of proceeds between the Series B Convertible Preferred Stock and Series B Warrants issued in both tranches.   The $294,838 represents the value of the adjustment to additional paid in capital related to the beneficial conversion feature of the Series B Convertible Preferred Stock.  The value adjustment was calculated by subtracting the fair market value of the underlying common stock issuable upon conversion of the Series B Convertible Preferred Stock on the date of the respective closing from the fair market value of the Series B Convertible Preferred Stock as determined when the Company performed a fair market value allocation of the proceeds to the Series B Convertible Preferred Stock and Series B Warrants.

Each share of Series B Convertible Preferred Stock will receive a cumulative dividend at the rate of 5% per annum of the Series B Purchase Price, payable semi-annually on June 30 and December 31, commencing on December 31, 2009 (with the first payment being pro-rated based on the number of days occurring between the date of issuance and December 31, 2009).  Dividends may be paid in cash or in shares of common stock at our option, subject to certain conditions.  The shares of Series B Convertible Preferred Stock also are entitled to a liquidation preference, such that in the event of any voluntary or involuntary liquidation, dissolution or winding up of our Company, the holders of Series B Convertible Preferred Stock will be paid out of the assets of the Company available for distribution to our stockholders before any payment shall be paid to the holders of common stock, an amount per share equal to the Series B Purchase Price, plus accrued and unpaid dividends.  The Series B Convertible Preferred Stock will be treated on an equivalent basis with respect to payments made in connection with a liquidation.  The Board approved the method of payment in the form of common stock for the December 31, 2009 dividend.  The Board approved the method of payment in the form of common stock for the June 30, 2010 dividend to the holders of Series B Convertible Preferred Stock issued in November 2009 and cash to the holders of Series B Convertible Preferred Stock issued in March 2010.  The Board approved the method of payment in the form of cash for the December 31, 2010 dividend to all holders of Series B Convertible Preferred Stock.

Each share of Series B Convertible Preferred Stock is convertible into 10 shares of common stock at any time at the option of the holder, subject to adjustment for stock splits, stock dividends, recapitalizations and similar transactions (the “Series B Conversion Ratio”).  Each share of Series B Convertible Preferred Stock will automatically be converted into shares of common stock at the Series B Conversion Ratio then in effect:  (i) if, after 12 months from the closing of the applicable tranche of the Series B Private Placement, the common stock trades on the Nasdaq Capital Market (or other primary trading market or exchange on which the common stock is then traded) at a price equal $5.64 for 20 out of 30 consecutive trading days with average daily trading volume of at least 10,000 shares or (ii) upon a registered public offering by the Company at a per share price equal to $5.64, with aggregate gross proceeds to the Company of not less than $10 million.  Unless waived under certain circumstances by the holder of the Series B Convertible Preferred Stock, such holder’s Series B Convertible Preferred Stock may not be converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.

The holders of Series B Convertible Preferred Stock are not entitled to vote on any matters presented to the stockholders of the Company for their action or consideration at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of meeting), except that the holders of Series B Convertible Preferred Stock may vote separately as a class on any matters that would amend, alter or repeal any provision of our Restated Articles of Organization, as amended, in a manner that adversely affects the powers, preferences or rights of the Series B Convertible Preferred Stock and such holders may also vote on any matters required by law.

At any time after February 12, 2014, upon 30 days written notice, we have the right to redeem the outstanding shares of Series B Convertible Preferred Stock at a price equal to the Series B Purchase Price, plus all accrued and unpaid dividends thereon.  The redemption price may be paid in two annual installments.  The Series B Convertible Preferred Stock and the Series A Convertible Preferred Stock will be treated on an equivalent basis with respect to payments made in connection with redemption.

Series B Warrants
The Series B Warrants issued in November 2009 have an exercise price equal to $23.80 and the Series B Warrants issued in March 2010 have an exercise price equal to $28.80, in each case with a term expiring on August 11, 2011.  The Series B Warrants permit the holder to conduct a “cashless exercise” at any time the holder of the Series B Warrant is an “affiliate” (as defined in the Securities Purchase Agreement) of the Company.   

The Series B Warrant exercise price and/or number of shares issuable upon exercise of the Series B Warrant will be subject to adjustment for stock dividends, stock splits or similar capital reorganizations, as set forth in the Series B Warrants.

Subject to the terms and conditions of the Series B Warrants, the Company has the right to call for cancellation the Series B Warrants if the volume weighted average price of our common stock on the Nasdaq Capital Market (or other primary trading market or exchange on which our common stock is then traded) equals or exceeds $4.70 for either (i) 10 consecutive trading days or (ii) 15 out of 25 consecutive trading days.

In connection with the Series B Private Placement on March 18, 2010, we issued warrants to our placement agent to purchase 1,679 shares of Series B Convertible Preferred Stock at $28.80 per share, expiring August 11, 2012.  The Series B Warrants and placement agent warrants were valued based on a Black-Scholes pricing model at the date of the grants.  The Series B Warrants and placement agent warrants vested immediately.  The relative fair value of the Series B Warrants was calculated to be $173,060 and was recorded to stockholders’ equity.  The assumptions for the Black-Scholes pricing model are represented in the table below for the warrants issued in both tranches reflected on a per share common stock equivalent basis.  The assumptions for the placement agent show the range of values for both tranches.

15-Month Series A Preferred Stock Warrant Call

On March 30, 2010, the Company called for cancellation any 15-Month Series A Preferred Stock Warrants that remained unexercised as of April 28, 2010.  In connection with this warrant call, 15-Month Series A Preferred Stock Warrants to purchase 98,372 shares of Series A Convertible Preferred Stock were exercised at $12.50 per share, for gross proceeds to the Company of $1,229,650, before deducting expenses associated with the warrant call notice.  15-Month Series A Preferred Stock Warrants to purchase an additional 10,150 shares of Preferred Stock were exercised on a cashless basis, resulting in the net issuance of 2,883 shares of Series A Convertible Preferred Stock.  Pursuant to the terms of the 15-Month Series A Preferred Stock Warrants, upon exercise of such warrants, the holders became entitled to receive an aggregate of 57,390 shares of common stock in payment of dividends on the Series A Convertible Preferred Stock paid on June 30, 2009 and December 31, 2009.

Series C Convertible Preferred Stock

On April 8, 2011 and April 12, 2011, we completed the first tranche of a private placement, pursuant to which we sold an aggregate of 55,048 units for a purchase price of $15.00 per unit, resulting in gross proceeds to us of $825,720 (the “Series C Private Placement”).  This was the first tranche of the $6 million Series C Private Placement.  .  In connection with the second tranche, the purchase price was reduced to $12.50 per unit and we issued an additional 11,011 units to the purchasers who participated in the first tranche, without any additional gross proceeds to us.  The second tranche closed on June 20, 2011 for the sale of 22,039 Series C Units for a purchase price of $12.50 per unit with gross proceeds of $275,485.  Each unit (“Series C Unit”) consists of (i) one share of Series C Convertible Preferred Stock, $0.01 par value per share (the “Series C Convertible Preferred Stock”) convertible into 10 shares of our Common Stock, (subject to adjustment for stock splits, stock dividends, recapitalization, etc.) and (ii) a three-year warrant to purchase 10 shares of our Common Stock at a per share exercise price equal to the sum of (i) the Common Stock equivalent of the Series C Purchase Price (ii) plus $0.88 (the “ Series C Warrant”).  The Series C Warrants will be exercisable until the close of business on the third anniversary of the applicable closing date.

We engaged an investment banker (the “Investment Banker”) to assist with the Series C Private Placement.  The Company paid the Investment Banker a cash retainer fee of $50,000 and issued a warrant to purchase 100,000 shares of Common Stock at an exercise price of $3.00 per share.  In connection with the Series C Private Placement, we paid the Investment Banker a fee of (i) approximately $66,000 cash, (ii) an expense allowance of approximately $16,500, (iii) a warrant to purchase 61,670 shares of Common Stock exercisable at a purchase price of $1.50, and (iv) a warrant to purchase 61,670 shares of Common Stock exercisable at a purchase price of $2.38.

The proceeds from the sale of each Series C Unit was allocated between the Series C Convertible Preferred Stock and the Common Stock Warrant based on the relative estimated fair value of each security.  The estimated fair value of the warrants was determined using the Black-Scholes formula, resulting in an allocation of the gross proceeds of $511,468 to the total warrants issued.  The allocation of the gross proceeds to the Series C Convertible Preferred Stock was $589,740.  In accordance with the provisions of FASB ASC 470-20, Debt with Conversion and Other Options , an additional adjustment between Additional Paid in Capital and Accumulated Deficit of $181,907 was recorded to reflect an implicit non-cash dividend related to the allocation of proceeds between the stock and warrants issued.  The $181,907 represents the value of the adjustment to additional paid in capital related to the beneficial conversion feature of the Series C Convertible Preferred Stock.  The value adjustment was calculated by subtracting the fair market value of the underlying common stock on April 7 and June 20 issuable upon conversion of the Series C Convertible Preferred Stock from the fair market value of the Series C Convertible Preferred Stock as determined when the Company performed a fair market value allocation of the proceeds to the Series C Convertible Preferred Stock and warrants.  The warrants are recorded as a liability.  See Note 3 “Warrant Liability” under Summary of Accounting Policies.

Each share of Series C Convertible Preferred Stock will receive a cumulative dividend at the rate of 5% per annum of the Series C’s respective tranche purchase price, payable semi-annually on June 30 and December 31, commencing on June 30, 2011 (with the first payment being pro-rated based on the number of days occurring between the date of issuance and June 30, 2011).  Dividends may be paid in cash or in shares of common stock at our option, subject to certain conditions.  The shares of Series C Convertible Preferred Stock also are entitled to a liquidation preference, such that in the event of any voluntary or involuntary liquidation, dissolution or winding up of our Company, the holders of Series C Convertible Preferred Stock will be paid out of the assets of the Company available for distribution to our stockholders before any payment shall be paid to the holders of common stock, an amount per share equal to the Series C Purchase Price, plus accrued and unpaid dividends.  The Series C Convertible Preferred Stock will be treated on an equivalent basis with respect to payments made in connection with a liquidation.

Each share of Series C Convertible Preferred Stock is convertible into 10 shares of common stock at any time at the option of the holder, subject to adjustment for stock splits, stock dividends, recapitalizations and similar transactions (the “Series C Conversion Ratio”).  Each share of Series C Convertible Preferred Stock will automatically be converted into shares of common stock at the Series C Conversion Ratio then in effect:  (i) if, after 12 months from the closing of the applicable tranche of the Series B Private Placement, the common stock trades on the Nasdaq Capital Market (or other primary trading market or exchange on which the common stock is then traded) at a price equal to three-tenths of the Series C Unit purchase price for 20 out of 30 consecutive trading days with average daily trading volume of at least 10,000 shares or (ii) upon a registered public offering by the Company at a per share price equal to at least three-tenths of the Series C Unit purchase price, with aggregate gross proceeds to the Company of not less than $10 million.  Unless waived under certain circumstances by the holder of the Series C Convertible Preferred Stock, such holder’s Series C Convertible Preferred Stock may not be converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.

The holders of Series C Convertible Preferred Stock are not entitled to vote on any matters presented to the stockholders of the Company for their action or consideration at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of meeting), except that the holders of Series C Convertible Preferred Stock may vote separately as a class on any matters that would amend, alter or repeal any provision of our Restated Articles of Organization, as amended, in a manner that adversely affects the powers, preferences or rights of the Series C Convertible Preferred Stock and such holders may also vote on any matters required by law.

If we consummate an equity financing (other than the exercise of employee stock options under the Company’s stock option plans, the Series C purchase agreement or the exercise of any Warrants, or the exercise or conversion of any currently outstanding Common Stock Equivalents) within twelve months after the initial Closing and the gross proceeds to the Company from the sale of the Units are less than $4 million, then each Series C holder may exchange all, but not less than all, of his, her or its Units for the equity securities issued in such next financing and shall become subject to the terms and conditions of such next financing; provided that the exchange of the purchaser’s units for next financing securities is permitted under the rules and regulations of the NASDAQ Trading Market then in effect.  The number of next financing securities into which a purchaser’s Series C Units may be exchanged shall be determined by dividing (a) the aggregate per unit purchase price at which the Series C units being exchanged were issued, by (b) the price per next financing security at which such securities were issued in the next financing.

At any time after February 12, 2014, upon 30 days written notice, we have the right to redeem the outstanding shares of Series C Convertible Preferred Stock at a price equal to the Series C purchase price, plus all accrued and unpaid dividends thereon.  The redemption price may be paid in two annual installments.  All holders of Series A, B, and C Convertible Preferred Stock will be treated on an equivalent basis with respect to payments made in connection with redemption.

Series C Warrants
The Series C Warrants have an exercise price equal to $2.13 with a term expiring on the third anniversary of the deal closing.  The Series C Warrants permit the holder to conduct a “cashless exercise” at any time the holder of the Series C Warrant is an “affiliate” (as defined in the Securities Purchase Agreement) of the Company.   

The Series C Warrant exercise price and/or number of shares issuable upon exercise of the Series C Warrant will be subject to adjustment for stock dividends, stock splits or similar capital reorganizations, as set forth in the Series C Warrants.

Subject to the terms and conditions of the Series C Warrants, the Company has the right to call for cancellation the Series C Warrants if the volume weighted average price of our common stock on the Nasdaq Capital Market (or other primary trading market or exchange on which our common stock is then traded) equals or exceeds two times the per common share exercise price for either (i) 10 consecutive trading days or (ii) 15 out of 25 consecutive trading days.


Common Stock

Shareholders Rights Plan

On March 3, 2003, our Board of Directors adopted a shareholder rights plan (the “Rights Plan”) and declared a distribution of one Right for each outstanding share of our common stock to shareholders of record at the close of business on March 21, 2003 (the “Rights”).  Initially, the Rights will trade automatically with the common stock and separate Right Certificates will not be issued.  The Rights Plan is designed to deter coercive or unfair takeover tactics and to ensure that all of our shareholders receive fair and equal treatment in the event of an unsolicited attempt to acquire the Company.  The Rights will expire on February 27, 2013 unless earlier redeemed or exchanged.  Each Right entitles the registered holder, subject to the terms of a Rights Agreement, to purchase from the Company one one-thousandth of a share of the Company’s Series A Junior Participating Preferred Stock at a purchase price of $45.00 per one one-thousandth of a share, subject to adjustment. In general, the Rights will not be exercisable until a subsequent distribution date which will only occur if a person or group acquires beneficial ownership of 15% or more of our common stock or announces a tender or exchange offer that would result in such person or group owning 15% or more of the common stock. With respect to any person or group who currently beneficially owns 15% or more of our common stock, the Rights will not become exercisable unless and until such person or group acquires beneficial ownership of additional shares of common stock.

Subject to certain limited exceptions, if a person or group acquires beneficial ownership of 15% or more of our outstanding common stock or if a current 15% beneficial owner acquires additional shares of common stock, each holder of a Right (other than the 15% holder whose Rights become void once such holder reaches the 15% threshold) will thereafter have a right to purchase, upon payment of the purchase price of the Right, that number of shares of our common stock which at the time of such transaction will have a market value equal to two times the purchase price of the Right.  In the event that, at any time after a person or group acquires 15% or more of our common stock, we are acquired in a merger or other business combination transaction or 50% or more of our consolidated assets or earning power are sold, each holder of a Right will thereafter have the right to purchase, upon payment of the purchase price of the Right, that number of shares of common stock of the acquiring company which at the time of such transaction will have a market value of two times the purchase price of the Right.

Our Board of Directors may exchange the Rights (other than Rights owned by such person or group which have become void), in whole or in part, at an exchange ratio of one share of common stock per Right (subject to adjustment).  At any time prior to the time any person or group acquires 15% or more of our common stock, the Board of Directors may redeem the Rights in whole, but not in part, at a price of $0.001 per Right.

Stock Options and Warrants

We did not grant employee stock options during the six months ended June 30, 2011 and 2010.

As of June 30, 2011, the total estimated fair value of unvested stock options to be amortized over their remaining vesting period was $13,872.  The non-cash, stock-based compensation expense associated with the vesting of these options is expected to be immaterial for the next two years.  The aggregate intrinsic value of stock options exercised during the six months ended June 30, 2011 is approximately $20,000.
