Preferred Stock

We are authorized to issue 1,000,000 shares of preferred stock with a par value of $0.01. Of the 1,000,000 shares of preferred stock:

As of December 31, 2012, there were no shares of Junior A, and Series A, B, C, E, and H 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”).

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 $1.72 in accordance with the terms of the 30-Month Common Stock Purchase Warrants.

On or about August 10, 2011, holders of 30-Month Common Stock Warrants to purchase 1,569,800 shares of Common Stock entered into an amendment to the 30-Month Common Stock Warrants which extended the expiration date of the warrants to August 11, 2012. On or about September 30, 2011, 30-Month Common Stock Warrants to purchase 1,556,750 shares of Common Stock were further amended to reduce the exercise price from $1.74 to $0.90 and to extend the term until August 12, 2016 and, with respect to affiliates, August 12, 2015. A 30-Month Common Stock Warrant to purchase 13,050 shares of Common Stock was not amended and was further adjusted by Common Stock dividends issued in October 2011 resulting in an effective exercise price of $1.72 per share, subject to future adjustment, with a term expiring on August 11, 2012.

Each share of Series A Convertible Preferred Stock received 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). The Company was permitted to pay dividends in cash or in shares of Common Stock at our option, subject to certain conditions.. The Board approved the final payment to Series A holders in the form of cCommon Stock  for accrued dividends through September 30, 2011.

On or about September 30, 2011, all 47 holders of both the outstanding Series A Convertible Preferred Stock and Series A 30-Month Common Stock Purchase Warrants, issued in the Series A Convertible Preferred Stock financing completed by the Company in February 2009, voluntarily converted an aggregate of 247,187 shares of Series A Preferred Stock into 2,471,870 shares of the Company’s Common Stock. The Company has no obligation or intention to issue any more shares of Series A Convertible Preferred Stock.

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 Placements”). Each Series B Unit consisted 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”).

On or about August 10, 2011, holders of the Series B Warrants to purchase 887,110 shares of Common Stock entered into an amendment to the Series B Warrants which extended the expiration date of the Series B Warrants to August 11, 2012 and provided that they would be issuable for the equivalent number of shares of Common Stock at a proportionate exercise price. On or about September 30, 2011, Series B Warrants to purchase 887,110 shares of Common Stock were further amended to reduce the exercise price from $2.38 to $1.43, for Series B Warrants issued in November 2009, and from $2.88 to $1.75, for Series B Warrants issued in March 2010. Series B Warrants also extended the term of the Series B Warrants until August 12, 2016 and until August 12, 2015 with respect to affiliates. All of the Series B Warrants are no longer exercisable for shares of Series B Convertible Preferred Stock.

On or about September 30, 2011, all of the outstanding shares of Series B Convertible Preferred Stock were voluntarily converted into shares of Common Stock.

Each share of Series B Convertible Preferred Stock received 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). The Company was permitted to pay dividends in cash or in shares of Common Stock at our option, subject to certain conditions. The shares of Series B Convertible Preferred Stock were also 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 would have been paid out of the assets of the Company available for distribution to our stockholders before any payment was 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 would have been treated on an equivalent basis with the holders of the Series A Convertible Preferred Stock and Series C Convertible Preferred Stock 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 dividends payable with respect to December 31, 2009 and the June 30, 2010 (to the holders of Series B Convertible Preferred Stock issued in November 2009). The Board approved the method of payment in the form of cash for the dividends payable with respect to June 30, 2010 (to the holders of Series B Convertible Preferred Stock issued in March 2010), December 31, 2010 and for all dividends accrued through December 31, 2012.

Each share of Series B Convertible Preferred Stock was 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 would have been automatically 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 traded on the OTC Market (or other primary trading market or exchange on which the Common Stock was 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 could not have been converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.

Series B Warrants

The Series B Warrants issued in November 2009 originally had an exercise price equal to $23.80 and the Series B Warrants issued in March 2010 originally had an exercise price equal to $28.80, in each case with a term expiring on August 11, 2011. The Series B Warrants currently have an exercise price of $1.43 for Series B Warrants issued in November 2009, and $1.75 for Series B Warrants issued in March 2010, in each case with a term expiring on August 12, 2016 and, with respect to affiliates, August 12, 2015. The Series B Warrants are currently exercisable for shares of Common Stock. 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.

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 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 (as defined below) for a purchase price of $12.50 per unit with gross proceeds of $275,485. Each unit (“Series C Unit”) consisted 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 are 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 the Investment Banker 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 61,638 shares of Common Stock exercisable at a purchase price of $1.50, and (iv) a warrant to purchase 61,638 shares of Common Stock exercisable at a purchase price of $2.38.

The proceeds from the sale of each Series C Unit were allocated between the Series C Convertible Preferred Stock and the Series C Warrants based on the residual method. The estimated fair value of the Series C Warrants was determined using a binomial formula, resulting in an allocation of the gross proceeds of $583,250 to the total warrants issued. The allocation of the gross proceeds to the Series C Convertible Preferred Stock was $517,958. In accordance with the provisions of ASC 470-20, an additional adjustment between Additional Paid in Capital and Accumulated Deficit of $476,434 was recorded to reflect an implicit non-cash dividend related to the allocation of proceeds between the stock and warrants issued. The $476,434 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. We used a binomial formula since the warrants have down-round protection and are recorded as a liability. See “Warrant Derivative Liability” section within this footnote.

Each share of Series C Convertible Preferred Stock will receive a cumulative dividend at the rate of 5% per annum of the 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. Prior to the conversion of all of the outstanding shares of Series A Convertible Preferred Stock and Series B Convertible Preferred Stock, the Series C Convertible Preferred Stock was treated on an equivalent basis with the Series A Convertible Preferred Stock and Series C Preferred Stock with respect to payments made in connection with a liquidation. The Company elected to pay the dividend payable on June 30, 2011 in cash.

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 C Private Placement, the Common Stock trades on the OTC 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 Private Placement or the exercise of any Series C 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 holder of Series C Units may exchange all, but not less than all, of his, her or its Series C 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 Series C 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. The requisite holders of the Series C Units waived such right with respect to the Company’s recently completed equity 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 Unit purchase price, plus all accrued and unpaid dividends thereon. The redemption price may be paid in two annual installments. All holders of Series 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 OTC 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.

On April 5, 2012, all 11 holders of outstanding Series C Convertible Preferred Stock and Series C Common Stock Purchase Warrants voluntarily converted an aggregate of 88,098 shares of Series C Preferred Stock into 1,372,247 shares of the Company’s Common Stock, and Series C Warrants to purchase an aggregate of 880,980 shares of the Company’sCommon Stock to warrants to purchase 686,125 shares of Common Stock in the Company.

Series D Convertible Preferred Stock

On November 11, 2011, we completed a registered direct offering, pursuant to which we sold an aggregate of 843 units for a purchase price of $1,000 per unit, resulting in gross proceeds to us of $843,000 (the “Series D Placement”). Each unit (“Series D Unit”) consisted of (i) one share of Series D Convertible Preferred Stock, $0.01 par value per share (the “Series D Convertible Preferred Stock”) convertible into 1,538.46 shares of our Common Stock, (subject to adjustment for stock splits, stock dividends, recapitalization, etc.) and (ii) one five-year warrant to purchase approximately 614 shares of our Common Stock at a per share exercise price of $0.81, subject to adjustment as provided in the Warrants (“Series D Warrant”). The Series D Warrants will be exercisable beginning on May 11, 2012 and until the close of business on the fifth anniversary of the initial exercise date.

We engaged an investment banker to assist with the Series D Placement. In connection with the Series D Placement, we paid the investment banker a fee of approximately $67,000 cash.

The proceeds from the sale of each Series D Unit were allocated between the Series D Convertible Preferred Stock and the Series D Warrants based on the residual method. The estimated fair value of the Series D Warrants was determined using a binomial formula, resulting in an allocation of the gross proceeds of $283,725 to the total warrants issued. The allocation of the gross proceeds to the Series D Convertible Preferred Stock was $559,275. In accordance with the provisions of ASC 470-20, an additional adjustment between Additional Paid in Capital and Accumulated Deficit of $530,140 was recorded to reflect an implicit non-cash dividend related to the allocation of proceeds between the stock and warrants issued. The $530,140 represents the value of the adjustment to additional paid in capital related to the beneficial conversion feature of the Series D Convertible Preferred Stock. The value adjustment was calculated by subtracting the fair market value of the underlying Common Stock on November 10, 2011 issuable upon conversion of the Series D Convertible Preferred Stock from the fair market value of the Series D Convertible Preferred Stock as determined when the Company performed a fair market value allocation of the proceeds to the Series D Convertible Preferred Stock and warrants. The warrants are recorded as a liability. See “Warrant Derivative Liability” below.

The Series D Convertible Preferred Stock will rank senior to the Company’s Common Stock and Series C Convertible Preferred Stock with respect to payments made upon liquidation, winding up or dissolution. Upon any liquidation, dissolution or winding up of the Company, after payment of the Company’s debts and liabilities, and before any payment is made to the holders of any junior securities, the holders of Series D Convertible Preferred Stock will first be entitled to be paid $1,000 per share subject to adjustment for accrued but unpaid dividends.

We may not pay any dividends on shares of Common Stock unless we also pay dividends on the Series D Convertible Preferred Stock in the same form and amount, on an as-if-converted basis, as dividends actually paid on shares of our Common Stock. Except for such dividends, no other dividends may be paid on the Series D Convertible Preferred Stock.

Each share of Series D Convertible Preferred Stock is convertible into 1,538.46 shares of Common Stock (based upon an initial conversion price of $0.65 per share) at any time at the option of the holder, subject to adjustment for stock splits, stock dividends, combinations, and similar recapitalization transactions (the “Series D Conversion Ratio”). Subject to certain exceptions, if the Company issues any shares of Common Stock or Common Stock equivalents at a per share price that is lower than the conversion price of the Series D Convertible Preferred Stock, the conversion price will be reduced to the per share price at which such shares of Common Stock or Common Stock equivalents are issued. Each share of Series D Convertible Preferred Stock will automatically be converted into shares of Common Stock at the Series D Conversion Ratio then in effect if, after six months from the closing of the Series D Placement, the Common Stock trades on the OTC Market (or other primary trading market or exchange on which the Common Stock is then traded) at a price equal to at least 300% of the then effective Series D Convertible Preferred Stock conversion price for 20 out of 30 consecutive trading days with each trading day having a volume of at least $50,000. Unless waived under certain circumstances by the holder of the Series D Convertible Preferred Stock, such holder’s Series D Convertible Preferred Stock may not be converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.

In addition, in the event we consummate a merger or consolidation with or into another person or other reorganization event in which our shares of Common Stock are converted or exchanged for securities, cash or other property, or we sell, lease, license or otherwise dispose of all or substantially all of our assets or we or another person acquire 50% or more of our outstanding shares of Common Stock, then following such event, the holders of the Series D Convertible Preferred Stock will be entitled to receive upon conversion of the Series D Convertible Preferred Stock the same kind and amount of securities, cash or property which the holders of the Series D Convertible Preferred Stock would have received had they converted the Series D Convertible Preferred Stock immediately prior to such fundamental transaction.

The holders of Series D 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 D Convertible Preferred Stock may vote separately as a class on any matters that would (i) amend, our Restated Articles of Organization, as amended, in a manner that adversely affects the rights of the Series D Convertible Preferred Stock, (ii) alter or change adversely the powers, preferences or rights of the Series D Convertible Preferred Stock or alter or amend the certificate of designation, (iii) authorize or create any class of shares ranking as to dividends, redemption or distribution of assets upon liquidation senior to, or otherwise pari passu with, the Series D Convertible Preferred Stock, or (iv) increase the number of authorized shares of Series D Convertible Preferred Stock.

If, within 12 months of the initial issuance of the Series D Convertible Preferred Stock, we issue any Common Stock, Common Stock equivalents, indebtedness or any combination thereof (a “Subsequent Financing”), the holders of Series D Convertible Preferred Stock will have the right to participate on a pro-rata basis in up to 50% of such Subsequent Financing.

During the year ended December 31, 2012, 443 shares of Series D Convertible Preferred Stock were converted to 681,538 shares of common stock.

Series D Warrants

The Series D Warrants have an exercise price equal to $0.81 per share of common stock. The Series D Warrants will be exercisable beginning on the six month anniversary of the date of issuance and expire five years from the initial exercise date. The Series D Warrants permit the holder to conduct a “cashless exercise” at any time a registration statement registering, or the prospectus contained therein is not available for, the issuance of the shares of Common Stock issuable upon exercise of the Series D Warrant, and under certain circumstances at the expiration of the Series D Warrants. The exercise price and/or number of shares of Common Stock issuable upon exercise of the Series D Warrants will be subject to adjustment for certain stock dividends, stock splits or similar capital reorganizations, as set forth in the Warrants. The exercise price is also subject to adjustment in the event that we issue any shares of Common Stock or Common Stock equivalents at a per share price that is lower than the exercise price for the Series D Warrants then in effect. Upon any such issuance, subject to certain exceptions, the exercise price will be reduced to the per share price at which such shares of Common Stock or Common Stock equivalents are issued. Unless waived under certain circumstance by the holder of a Warrant, such holder may not exercise the Warrant if upon such exercise the holder’s beneficial ownership of the Company’s Common Stock would exceed certain thresholds.

In the event we consummate a merger or consolidation with or into another person or other reorganization event in which our shares of Common Stock are converted or exchanged for securities, cash or other property, or we sell, lease, license or otherwise dispose of all or substantially all of our assets or we or another person acquire 50% or more of our outstanding shares of Common Stock, then following such event, the holders of the Series D Warrants will be entitled to receive upon exercise of the Series D Warrants the same kind and amount of securities, cash or property which the holders would have received had they exercised the Series D Warrants immediately prior to such fundamental transaction.

Series E Convertible Preferred Stock

On April 9, 2012, we completed a registered direct offering with Ironridge Global IV Ltd. (“Ironridge”), pursuant to which we sold an aggregate of 500 shares of our Series E Convertible Preferred Stock to Ironridge for a purchase price of $1,000 per share or an aggregate purchase price of $500,000 (“Series E Preferred Stock”). Each share of Series E Preferred Stock was convertible into approximately 980 shares of our Common Stock. The Series E Preferred Stock was entitled to a yearly dividend at a rate of 10.5% per year, subject to a credit risk and make-whole adjustment, and was payable in cash or shares of Common Stock at our election. Under certain conditions and subject to certain limitations, we could have required Ironridge to convert their Series E Convertible Preferred Stock into Common Stock. In connection with this registered direct offering, our investment banker received a fee of $40,000. The make-whole dividends were payable any time after the closing on April 9, 2012 at the option of the holder; therefore, we recognized the full value of $262,500 as a current liability and charged this amount immediately to accumulated deficit. We adjusted the value as of September 30, 2012 based on the closing bid on September 28, 2012. We paid $128,402 of make-whole dividends in the Company’s Common Stock and $67,500 in cash. Ironridge converted all 500 shares of Series E Preferred Stock into 490,196 common shares in 2012.

The Series E Preferred Stock ranked senior to the Company’s Common Stock for so long as at least 250 shares of Series E Preferred Stock remained outstanding and pari passu thereafter and junior to the Series D Preferred Stock with respect to payments made upon liquidation, winding up or dissolution. Upon any liquidation, dissolution or winding up of the Company, after payment of the Company’s debts and liabilities, and before any payment was made to the holders of any junior securities, the holders of Series E Convertible Preferred Stock were first entitled to be paid $1,000 per share subject to adjustment for accrued but unpaid dividends.

We were not allowed to pay any dividends on shares of Common Stock so long as any shares of Series E Preferred Stock were outstanding.

Each share of Series E Preferred Stock was convertible into 980.39 shares of Common Stock (based upon an initial conversion price of $1.02 per share) at any time at the option of the holder, subject to adjustment for stock splits, stock dividends, combinations, and similar recapitalization transactions (the “Series E Conversion Ratio”). At our option, each share of Series E Preferred Stock could have been converted into shares of Common Stock at the Series E Conversion Ratio then in effect if, theCommon Stock trades on the OTC Capital Market (or other primary trading market or exchange on which the Common Stock was then traded) at a price equal to at least $2.00 for 20 out of 25 consecutive trading days. Unless waived under certain circumstances by the holder of the Series E Preferred Stock, such holder’s Series E Preferred Stock may not have been converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.

Subject to the rights of the holders of Series D Preferred Stock, for so long as at least 250 shares of Series E Preferred Stock remained outstanding, upon any liquidation, dissolution or winding up of the Company, whether voluntary or involuntary (each a “Liquidation Event”), after payment or provision for payment of debts and other liabilities of the Company, the holders of Series E Preferred Stock would have been entitled to be paid out of the assets of the Company available for distribution to its stockholders an amount with respect to each share of Series E Preferred Stock equal to $1,000, plus any accrued but unpaid dividends thereon (the “Series E Liquidation Value”), before any distribution or payment would have been made to the holders of Common Stock. Subject to the rights of the holders of Series D Preferred Stock, at any time that fewer than 250 shares of Series E Preferred Stock remained outstanding, upon the occurrence of any Liquidation Event, after payment or provision for payment of debts and other liabilities of the Company, pari passu with any distribution or payment made to the holders of Common Stock by reason of their ownership thereof, the holders of Series E Preferred Stock would have been entitled to be paid out of the assets of the Company available for distribution to its stockholders the Series E Liquidation Value. For so long as at least 250 shares of Series E Preferred Stock remained outstanding, if, upon the occurrence of any Liquidation Event, the amounts payable with respect to the shares of Series E Preferred Stock are not paid in full, the holders of shares of Series E Preferred Stock would have shared equally and ratably with each other in any distribution of assets of the Company in proportion to the Series E Liquidation Value, if any, to which each such holder was entitled, before any distribution or payment shall have been made to holders of Common Stock. At any time that fewer than 250 shares of Series E Preferred Stock remained outstanding, if, upon the occurrence of any Liquidation Event, the amounts payable with respect to the shares of Series E Preferred Stock were not paid in full, the holders of shares of Series E Preferred Stock would have received the Series E Liquidation Value per share of Series E Preferred Stock on a proportionate and pari passu basis with the holders of Common Stock.

The holders of Series E Preferred Stock were 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 E Preferred Stock may have voted separately as a class on any matters that would (i) amend our Restated Articles of Organization, as amended, in a manner that adversely affects the rights of the Series E Preferred Stock, (ii) alter or change adversely the powers, preferences or rights of the Series E Preferred Stock or alter or amend the certificate of designation, (iii) authorize or create any class of shares ranking as to dividends, redemption or distribution of assets upon liquidation senior to, or otherwise pari passu with, the Series E Preferred Stock, or (iv) increase the number of authorized shares of Series E Preferred Stock.

No shares of Series E Convertible Preferred Stock remained outstanding as of December 31, 2012.

Series G Convertible Preferred Stock

On July 6 and November 15, 2012, we completed a private placement, pursuant to which we sold an aggregate of 145,320 units for a purchase price of $5.00 per unit (the “Series G Purchase Price”), resulting in gross proceeds to us of $726,600 (the “Series G Private Placement”). Each unit (“Series G Unit”) consists of (i) one share of Series G Convertible Preferred Stock, $0.01 par value per share (the “Series G 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 5 shares of our common stock at a per share exercise price of $0.50 (the “Series G Warrant”). The Series G Warrants will be exercisable until the close of business on the third anniversary of the applicable closing date of the Series G Private Placement. Of the $726,600 invested in the Series G Private Placement, $31,100 was received in cash and $695,500 was from the conversion of outstanding indebtedness and accrued board of directors’ fees.

Each share of Series G Preferred Stock will receive a cumulative dividend at the annual rate of (i) four percent (4%) on those shares of Series G Preferred Stock purchased from the Company by an individual purchaser with an aggregate investment of less than $100,000, (ii) six percent (6%) on those shares of Series G Preferred Stock purchased from the Company by an individual purchaser with an aggregate investment of at least $100,000 but less than $250,000, and (iii) twelve percent (12%) on those shares of Series G Preferred Stock purchased from the Company by an individual purchaser with an aggregate investment of at least $250,000. Dividends accruing on the Series G Preferred Stock shall accrue from day to day until, and shall be paid within fifteen (15) days of, the first anniversary of, the original issue date of the Series G Preferred Stock; provided, however, if any shares of the Company’s Series E Preferred Stock are outstanding at such time, payment of the accrued dividends on the Series G Preferred Stock shall be deferred until no such shares of Series E Convertible Preferred Stock remain outstanding. The Company may pay accrued dividends on the Series G Preferred Stock in cash or in shares of its Common Stock equal to the volume weighted average price of the Common Stock as reported by the OTC QB Market for the ten (10) trading days immediately preceding the Series G’s first anniversary.

At the election of the Company and upon required advanced notice, each share of Series G Preferred Stock will automatically be converted into shares of Common Stock at the Conversion Ratio then in effect: (i) if, after 6 months from the original issuance date of the Series G Preferred Stock , the Common Stock trades on the OTC QB Market (or other primary trading market or exchange on which the Common Stock is then traded) at a price equal to at least $0.75, for 7 out of 10 consecutive trading days with average daily trading volume of at least 10,000 shares, (ii) on or after the first anniversary of the original issuance date of the Series G Preferred Stock or (iii) upon completion of a firm-commitment underwritten registered public offering by the Company at a per share price equal to at least $0.75, with aggregate gross proceeds to the Company of not less than $2.5 million. Unless waived under certain circumstances by the holder of the Series G Preferred Stock, such holder’s Series G Preferred Stock may not be converted if upon such conversion the holder’s beneficial ownership would exceed certain thresholds.

The holders of Series G 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 as required by law.

Series G Warrants

The Series G Warrants issued in the Series G Private Placement have an exercise price equal to $0.50 per share, with a term expiring on July 6, 2015. The Series G Warrants also permit the holder to conduct a “cashless exercise” at any time the holder of the Series G Warrant is an affiliate of the Company. The exercise price and/or number of shares issuable upon exercise of the Series G Warrants will be subject to adjustment for stock dividends, stock splits or similar capital reorganizations, as set forth in the Series G Warrants.

Subject to the terms and conditions of the Series G Warrants, at any time commencing six months from the closing date the Company has the right to call for cancellation of the Series G Warrants if the volume weighted average price of its Common Stock on the OTC QB Market (or other primary trading market or exchange on which our Common Stock is then traded) equals or exceeds three times the per share exercise price of the Warrants for either (i) 10 consecutive trading days or (ii) 15 out of 25 consecutive trading days.

In connection with our sale of Series G Units, we agreed that for each share of Series G Preferred Stock purchased by an investor, the exercise price of one warrant to purchase one share of Common Stock, previously issued to the investor in prior offerings by the Company to purchase Common Stock of the Company held of record by such investor, shall be reduced to $0.60 per share and will remain at such reduced exercise price until the expiration date of the warrants.

In connection with the sale of Series G Units, we treated the reduction in exercise price as a warrant amendment and calculated the fair value of 1,495,022 warrants with the reduced exercise price of $0.60, as described above, using the Black-Scholes model with the below assumptions. The Company has determined that the fair value of the amended warrants increased as compared with the fair value of the original warrants immediately prior to amendment.

In connection with the warrant amendments, we calculated the fair value of the warrants, as described above, using a Black-Scholes model with the below assumptions.

We recorded an increased incremental value of $5,347 for the warrant amendment and treated the excess of fair value of the warrants as a deemed dividend.

Series H Convertible Preferred Stock

On December 28, 2012 the Company amended the Articles of Incorporation to authorize 10,000 shares of Series H Convertible Preferred Stock. On January 4, 2013, the Company reported that it had entered into a securities purchase and exchange agreement with an investor, pursuant to which the Company agreed to exchange an aggregate of 10,000 shares of a newly created series of preferred stock, designated Series H Convertible Preferred Stock, par value $0.01 per share (the “Series H Preferred Stock”) for 1,000,000 shares of the Company’s Common Stock, par value $0.01 per share of Common Stock held by the investor in a non-cash transaction. The investor originally purchased the Common Stock from the Company for $0.8025 per share. The exchange ratio was 100 shares of Common Stock per share of Series H Preferred Stock at a stated conversion price of $0.8025 per share.

 Common Stock

Shareholders Purchase Rights Plan

On March 3, 2003, our Board of Directors adopted a shareholder purchase 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 Plan was not adopted in response to any effort to acquire the Company and the Board is not aware of any such effort. 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 its 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

Our stockholders approved our amended 2005 Equity Incentive Plan (the “Plan”) pursuant to which an aggregate of 1,800,000 shares of our Common Stock were reserved for issuance upon exercise of stock options or other equity awards made under the Plan. Under the Plan, we may award stock options, shares of Common Stock, and other equity interests in the Company to employees, officers, directors, consultants, and advisors, and to any other persons the Board of Directors deems appropriate. As of December 31, 2012, options to acquire 1,572,750 shares were outstanding under the Plan with 227,250 shares available for future grant under the Plan.

As of December 31, 2012, options to acquire 33,000 shares are outstanding under the 1999 Non-qualified Stock Option Plan. No additional options may be granted under the 1999 Non-qualified Stock Option Plan.

All of the outstanding options had an exercise price that was above the Company’s Common Stock share price on December 31, 2012.

The following tables summarize information concerning options and warrants outstanding and exercisable:

There was $101,939 of total unrecognized compensation cost, net of estimated forfeitures, related to non-vested stock options granted as of December 31, 2012. This cost is expected to be recognized over a period of 3.1 years, and will be adjusted for any future changes in estimated forfeitures.

Sale of Common Stock

On February 7, 2012, we completed a private placement with 7 accredited investors, pursuant to which we sold an aggregate of 971,867 shares of Common Stock, $0.01 par value (“Shares”), resulting in gross proceeds to us of $800,000 (the “Private Placement”). The price per unit was $0.8025 for units consisting of 789,350 shares of Common Stock and warrants to purchase 394,677 shares of Common Stock, and was $0.9125 for units consisting of the remaining 182,517 shares of Common Stock and warrants to purchase 91,260 shares of Common Stock. Of the $800,000 invested in the private placement, $412,453 was received in cash and $387,547 was from the conversion of outstanding principal and interest on convertible promissory notes issued by us in 2011.

Each unit consists of one share of Common Stock and a warrant to purchase one-half share of Common Stock. The warrants are exercisable for a period of five years, commencing on August 7, 2012, at an exercise price of $0.74 per share for the purchasers of the 789,350 shares, and $0.85 per share for the purchasers of the 182,517 shares. The warrants permit the holder to conduct a “cashless exercise” at any time the holder is an affiliate. The exercise price and/or number of shares of Common Stock issuable upon exercise of the warrants will be subject to adjustment for certain stock dividends, stock splits or similar capital reorganizations.

In connection with the Private Placement, we paid our investment banker a fee of $35,000 for providing advisory services. We accounted for this fee as a reduction in the gross proceeds received from the Private Placement.

 Common Stock Issuances

On January 31, 2012, we issued 100,000 shares of restricted Common Stock to an investor relations firm in payment of services to be rendered over one year. We recorded $72,000 for this issuance of which will be amortized over the year. On March 2, 2012, we issued 22,500 shares of restricted Common Stock to an investor relations firm for payment of services already rendered over the prior three months. We recorded $13,950 for this issuance as expense. On April 26, 2012, we issued 17,500 shares of restricted Common Stock to two investor relations firms for payment of services to be rendered over one month. We recorded $9,625 for this issuance as expense. On April 27, 2012, we issued 100,000 shares of restricted Common Stock to an investor relations firm for payment of services to be rendered over six months. We recorded $60,000 for this issuance as expense. On August 13, 2012, we issued 350,000 shares of restricted Common Stock to an investor relations firm for payment of services to be rendered over one year. We recorded $140,000 for this issuance of which $59,947was recorded as expense and $85,053 that will be amortized over the remaining months of service. On October 17, 2012 we issued 60,000 shares of restricted Common Stock to three investor relations firms for services rendered and recognized $24,000 as expense. On October 18, 2012 we issued 50,000 shares of restricted Common Stock to an investor relations firm for services rendered and recognized $20,000 as expense. On October 19, 2012 we issued 100,000 shares of restricted Common Stock to an investor relations firm for services rendered and recognized $20,000 as expense and $20,000 that will be amortized over the remaining months of service. On October 19, we issued 100,000 shares of stock to the Company’s CEO to compensate him for unused personal time off and recognized expense of $40,000. On October 29, 2012 we issued 50,000 shares of restricted Common Stock to an investor relations firm and recognized $10,000 in expense and $10,000 that will be amortized over the remaining months of service. On November 1, 2012 we issued 175,000 shares of restricted Common Stock to two investor relations firms for services rendered and recognized expense of $40,000 and $30,000 that will be amortized over the remaining months of service. We valued the above stock issuances using the greater of the estimated fair value of the services received or the Company’s stock price on date of issuance.

Warrant Derivative Liability

The Series C Warrants issued in connection with the Series C Convertible Preferred Stock private placement and the Series D Warrants issued in connection with the registered direct offering of Series D Convertible Preferred are measured at fair value and liability-classified because the Series C Warrants are entitled to certain rights in subsequent financings and the Series D Warrants contain “down-round protection” and therefore, do not meet the scope exception for treatment as a derivative under ASC 815, Derivatives and Hedging, (“ASC 815”). Since “down-round protection” is not an input into the calculation of the fair value of the warrants, the warrants cannot be considered indexed to the Company’s own stock which is a requirement for the scope exception as outlined under ASC 815. The estimated fair value of the warrants was determined using the binomial model, resulting in an allocation of the gross proceeds of $583,250 to the total warrants issued in the Series C private placement and $283,725 to the warrants issued in the Series D registered direct offering. The fair value will be affected by changes in inputs to that model including our stock price, expected stock price volatility, the contractual term, and the risk-free interest rate. We will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire or are amended in a way that would no longer require these warrants to be classified as a liability, whichever comes first. The down-round protection for the Series C Warrants expired 12 months subsequent to the issuance of the Series C Units, and the down-round protection for the Series D Warrants survives for the life of the Series D Warrants which ends in May 2017.

On April 5, 2012, all 11 holders of outstanding Series C Convertible Preferred Stock and Series C Common Stock Purchase Warrants voluntarily converted an aggregate of 88,098 shares of Series C Preferred Stock into 1,372,247 shares of the Company’s Common Stock, and Series C Warrants to purchase an aggregate of 880,980 shares of the Company’s Common Stock to warrants to purchase 686,125 shares of Common Stock in the Company.

The assumptions for the binomial pricing model are represented in the table below for the warrants issued in both tranches of the Series C private placement reflected on a per share Common Stock equivalent basis.

The assumptions for the warrants issued to the investment banker show the range of values for both tranches. The investment banker received two sets of warrants in each tranche with half of the warrants assigned a different exercise price.

The assumptions for the binomial pricing model are represented in the table below for the warrants issued in the Series D private placement reflected on a per share Common Stock equivalent basis.

As of December 31, 2012, the value of the Series C and D Warrants has decreased to $160,812.
