ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

. . .

Restatement

In connection with equity financings on May 11 and 19, 2009, we issued warrants (the “Warrants”) that are single compound derivatives containing both an embedded right to obtain stock upon exercise (a “Call”) and a series of embedded rights to settle the Warrants for cash upon the occurrence of certain events (each, a “Put”). Generally, the Put provisions allow the Warrant Holders liquidity protection; the right to receive cash in certain situations where the Holders would not have a means of readily selling the shares issuable upon exercise of the Warrants (e.g., where there would no longer be a significant public market for our common stock). However, because the contractual formula used to determine the cash settlement value of the embedded Put requires use of certain assumptions, the cash settlement value of the embedded Put can differ from the fair value of the unexercised embedded Call option at the time the embedded Put option is exercised. Specifically, the Put rights would be triggered upon the happening of a “Fundamental Transaction” (as defined below) that also is (1) an all cash transaction; (2) a “Rule 13e-3 transaction” under the Exchange Act (where the Company would be taken private); or (3) a transaction involving a person or entity not traded on a national securities exchange. “Fundamental Transactions” include (i) a merger or consolidation of the Company with or into another person or entity; (ii) a sale, lease, license, transfer or other disposition of all or substantially all of the Company’s assets; (iii) any purchase offer, tender offer or exchange offer in which holders of Company Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property, which offer has been accepted by the holders of 50% or more of the Company’s outstanding Common Stock; (iv) a reclassification, reorganization or recapitalization of the Common Stock pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property; or (v) a stock purchase or other business combination with another person or entity is effected pursuant to which such other person or entity acquires more than 50% of the outstanding shares of Common Stock. Pursuant to the Warrants, the Put rights enable the Warrant Holders to receive cash in the amount of the Black-Scholes value is obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Warrant expiration date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Warrant expiration date.

A-1

Initially, we determined that these Warrants created a related Liability in accordance with ASC 480-10-55-29 & 30 due to the fact that the Warrants could be settled for cash as discussed above. In our estimation of the value of this Liability, we interpreted and applied the concept of “Fair Value” from ASC 820 (formally SFAS 157). After reviewing current accounting literature and the findings and opinion of an independent appraiser in determining proper accounting treatment, we took into account the extreme unlikelihood of the occurrence of a Fundamental Transaction triggering a right to cash settlement as a probability factor in applying a Black-Scholes-Merton valuation of the Warrants. As a result, we deemed the fair value of the Warrants to be immaterial and, therefore, we stated the Warrants’ related Liability from May 31, 2009 through December 31, 2009 at zero.

On September 15, 2010, we received a comment letter from the Securities and Exchange Commission (“SEC”) concerning its review of our annual report on Form 10-K, as amended, for the year ended December 31, 2009. During the process of resolving the SEC’s comments, the SEC Staff alerted us that they did not agree with our method of computing the fair value of the Warrants as discussed above.

As a result, on December 22, 2010, after discussion with McGladrey & Pullen, LLP, our independent registered public accounting firm, our Audit Committee determined that the previously issued financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009 and in our Forms 10-Q for the periods ended March 31, 2010, June 30, 2010 and September 30, 2010 and in our Forms 10-Q for the periods ended June 30, 2009 and September 30, 2009, should not be relied upon. We have restated the financial statements for the year ended December 31, 2009 contained herein and will restate the financial statements contained in our Forms 10-Q for the periods ended March 31, 2010, June 30, 2010 and September 30, 2010 (including the comparable periods ended June 30, 2009 and September 30, 2009) to reflect the revised value of this Liability.

The restatements reflect the recalculation of the fair value of the Warrants using a Monte Carlo Simulation approach, applying critical assumptions provided by Management reflecting conditions at the valuation date. The Monte Carlo Simulation approach incorporates the incremental value of the Put rights available to the Warrant Holders. The fair value of Warrants ranged from $0.37 to $2.14 during 2009 and ranged from $0.37 to $0.38 at December 31, 2009.

The Company recomputes the fair value of the Warrants at the end of each quarterly reporting period. Such value computation includes subjective input assumptions that are consistently applied each period. If the Company were to alter its assumptions or the numbers input based on such assumptions, the resulting fair value could be materially different.

Fair value at measurement dates during the period from Warrants’ issuances at May 10, 2009, May 18, 2009 and May 21, 2009 to December 31, 2009, were estimated using the following assumptions:


Underlying price per share	$0.56 - $2.54
Exercise price per share	$1.10 – $1.65
Risk-free interest rate	0.19% - 2.67%
Expected holding period	0.122 - 5.50 years
Expected volatility	94.99% – 226.46%
Expected dividend yield	None

A-2

The significant assumptions using the Monte Carlo Simulation approach for valuation of the Warrants are:

(i) Risk-Free Interest Rate. The risk-free interest rates for the Warrants are based on U.S Treasury constant maturities for periods commensurate with the remaining expected holding periods of the warrants.

(ii) Expected Holding Period. The expected holding period represents the period of time that the Warrants are expected to be outstanding until they are exercised. The Company utilizes the remaining contractual term of the Warrants at each valuation date as the expected holding period.

(iii) Expected Volatility. Expected stock volatility is based on daily observations of the Company’s historical stock values for a period commensurate with the remaining expected holding period on the last day of the period for which the computation is made.

(iv) Expected Dividend Yield. Expected dividend yield is based on the Company’s anticipated dividend payments over the remaining expected holding period. As the Company has never issued dividends, the expected dividend yield is $-0- and this assumption will be continued in future calculations unless the Company changes its dividend policy.

(v) Expected Probability of a Fundamental Transaction. The possibility of the occurrence of a Fundamental Transaction triggering a Put right is extremely remote. As discussed above, a Put right would only arise if a Fundamental Transaction 1) is an all cash transaction; (2) results in the Company going private; or (3) is a transaction involving a person or entity not traded on a national securities exchange. The Company believes such an occurrence is highly unlikely because:

The Company only has one product that is FDA approved;

The Company will have to perform additional clinical trials for FDA approval of its flagship product;

Industry and market conditions continue to include a global market recession, adding risk to any transaction;

Available capital for a potential buyer in a cash transaction continues to be limited;

The nature of a life sciences company is heavily dependent on future funding and high fixed costs, including Research & Development;

According to Forbes.com, of approximately 17,000 public companies, fewer than 30 went private in 2008 and less than 100 were completed in 2007, representing 0.18% and 0.6%, respectively. This would be further reduced based on the nature of a life sciences company and the potential lack of revenues, cash flows and the Company’s funding needs; and

The Company's Rights Agreement makes it less attractive to a potential buyer.

With the above factors utilized in analysis of the likelihood of the Put's potential Liability, the Company estimated the range of probabilities related to a Put right being triggered as:

Range of Probability	Probability
Low	0.5%
Medium	1.0%
High	5.0%

The Monte Carlo Simulation incorporated a 5.0% probability of a Fundamental Transaction.

A-3

(vi) Expected Timing of Announcement of a Fundamental Transaction. As the Company has no specific expectation of a Fundamental Transaction, for reasons elucidated above, the Company utilized a discrete uniform probability distribution over the Expected Holding Period to model in the potential announcement of a Fundamental Transaction occurring during the Expected Holding Period.

(vii) Expected 100 Day Volatility at Announcement of a Fundamental Transaction. An estimate of future volatility is necessary as there is no mechanism for directly measuring future stock price movements. Daily observations of the Company’s historical stock values for the 100 days immediately prior to the Warrants’ grant dates, with a floor of 100%, were utilized as a proxy for the future volatility.

(viii) Expected Risk-Free Interest Rate at Announcement of a Fundamental Transaction. The Company utilized a risk-free interest rate corresponding to the forward U.S. Treasury rate for the period equal to the time between the date forecast for the public announcement of a Fundamental Transaction and the Warrant expiration date for each simulation.

(ix) Expected Time Between Announcement and Consummation of a Fundamental Transaction. The expected time between the announcement and the consummation of a Fundamental Transaction is based on the Company’s experience with the due diligence process performed by acquirers, and is estimated to be six months. The Monte Carlo Simulation approach incorporates this additional period to reflect the delay Warrant Holders would experience in receiving the proceeds of the Put.

As a result of the corrections in the valuation of the Liabilities as of December 31, 2009 described above, we have restated our consolidated financial statements in this amended report as follows:

NOTES:

(a)	The total initial estimated fair value of the Liability related to the Warrants was $17,359,000 at the date of their issuance in May 2009. In order to record this Liability, an adjustment will be made to decrease Additional Paid-In Capital and increase Liabilities by $17,359,000.

(b)

In May 2009 and June 2009, some of these Warrants were exercised resulting in total non-cash losses of $3,675,000. Prior to each exercise, the individual Warrant’s fair value was revalued. The revaluation adjustments were made to increase the above mentioned Warrants’ Liability of $17,359,000 by the related $3,675,000 loss and then, upon exercise, reduce the Warrants’ Liability value by $7,417,000 for the exercised Warrants.

(c)

The estimated fair value of the Liability related to the Warrants was revalued at the end of each fiscal quarter from June 2009 through December 31, 2009. Due to the decreasing trading value of our stock during this period, at December 31, 2009, the value of the Liability related to the remaining outstanding Warrants will be $3,684,000. The June to December 2009 year to date adjustments to record the change in fair value for the remaining Warrants’ Liability will be $9,933,000, resulting in a related non-cash gain of $9,933,000.

None of the above issues from this non-cash adjustment will actually affect our revenues, operating expenses, liquidity or cash flows from past or future operations, except in the highly unlikely event that a Put right is triggered under the Warrants.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

. . .

(17) Fair Value

The Company is required under GAAP to disclose information about the fair value of all the Company’s financial instruments, whether or not these instruments are measured at fair value on the Company’s consolidated balance sheet.

The Company estimates that the fair values of cash and cash equivalents, other assets, accounts payable and accrued expenses approximate their carrying values due to the short-term maturities of these items. The Company also has certain warrants with a cash settlement right in the unlikely occurrence of a Fundamental Transaction. For a discussion about how the Company values these Warrants, please see “Note 18 – Restatement” below).

On January 1, 2008, the Company adopted new accounting guidance (codified at FASB ASC 820 and formerly Statement No. 157 Fair Value Measurements) that defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The guidance does not impose any new requirements around which assets and liabilities are to be measured at fair value, and instead applies to asset and liability balances required or permitted to be measured at fair value under existing accounting pronouncements. The Company measures its warrant liability at fair value.

FASB ASC 820-10-35-37 (formerly SFAS No. 157) establishes a valuation hierarchy based on the transparency of inputs used in the valuation of an asset or liability. Classification is based on the lowest level of inputs that is significant to the fair value measurement. The valuation hierarchy contains three levels:

Level 1 – Quoted prices are available in active markets for identical assets or liabilities at the reporting date.

Level 2 – Observable inputs other than Level 1 prices such as quote prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or other valuation techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. As of December 31, 2009, the Company has classified the warrants with embedded call and put rights as Level 3. Management evaluates a variety of inputs and then estimates fair value based on those inputs. As discussed below in Note 18 - Restatement, the Company utilized the Monte Carlo Simulation approach in valuing these warrants.

A-12

The table below presents the balances of assets and liabilities measured at fair value on a recurring basis by level within the hierarchy as of December, 31, 2009:

	Total		Level 1		Level 2		Level 3

(18) Restatement

In connection with equity financings on May 11 and 19, 2009, the Company issued warrants (the “Warrants”) that are single compound derivatives containing both an embedded right to obtain stock upon exercise (a “Call”) and a series of embedded rights to settle the Warrants for cash upon the occurrence of certain events (each, a “Put”). Generally, the Put provisions allow the Warrant Holders liquidity protection; the right to receive cash in certain situations where the Holders would not have a means of readily selling the shares issuable upon exercise of the Warrants (e.g., where there would no longer be a significant public market for our common stock). However because the contractual formula used to determine the cash settlement value of the embedded Put requires use of certain assumptions, the cash settlement value of the embedded Put can differ from the fair value of the unexercised embedded Call option at the time the embedded Put option is exercised. Specifically, the Put rights would be triggered upon the happening of a “Fundamental Transaction” (as defined below) that also is (1) an all cash transaction; (2) a “Rule 13e-3 transaction” under the Exchange Act (where the Company would be taken private); or (3) a transaction involving a person or entity not traded on a national securities exchange. “Fundamental Transactions” include (i) a merger or consolidation of the Company with or into another person or entity; (ii) a sale, lease, license, transfer or other disposition of all or substantially all of the Company’s assets; (iii) any purchase offer, tender offer or exchange offer in which holders of Company Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property, which offer has been accepted by the holders of 50% or more of the Company’s outstanding Common Stock; (iv) a reclassification, reorganization or recapitalization of the Common Stock pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property; or (v) a stock purchase or other business combination with another person or entity is effected pursuant to which such other person or entity acquires more than 50% of the outstanding shares of Common Stock. Pursuant to the Warrants, the Put rights enable the Warrant Holders to receive cash in the amount of the Black-Scholes value is obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Warrant expiration date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Warrant expiration date.

A-13

Initially, the Company determined that these Warrants created a related Liability in accordance with ASC 480-10-55-29 & 30 due to the fact that the Warrants could be settled for cash as discussed above. In their estimation of the value of this Liability, the Company interpreted and applied the concept of “Fair Value” from ASC 820 (formally SFAS 157). After reviewing current accounting literature and the findings and opinion of an independent appraiser in determining proper accounting treatment, the Company took into account the extreme unlikelihood of the occurrence of a Fundamental Transaction triggering a right to cash settlement as a probability factor in applying a Black-Scholes-Merton valuation of the Warrants. As a result, Management deemed the fair value of the Warrants to be immaterial and, therefore, we stated the Warrants’ related Liability from May 31, 2009 through December 31, 2009 at zero.

On September 15, 2010, the Company received a comment letter from the Securities and Exchange Commission (“SEC”) concerning its review of our annual report on Form 10-K, as amended, for the year ended December 31, 2009. During the process of resolving the SEC’s comments, the SEC Staff alerted Management that they did not agree with their method of computing the fair value of the Warrants as discussed above.

As a result, on December 22, 2010, after discussion with McGladrey & Pullen, LLP, the Company’s independent registered public accounting firm, the Company’s Audit Committee determined that the previously issued financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009 and in our Forms 10-Q for the periods ended March 31, 2010, June 30, 2010 and September 30, 2010 and in our Forms 10-Q for the periods ended June 30, 2009 and September 30, 2009, should not be relied upon. Management has restated the financial statements for the year ended December 31, 2009 contained herein and will restate the financial statements contained in our Forms 10-Q for the periods ended March 31, 2010, June 30, 2010 and September 30, 2010 (including the comparable periods ended June 30, 2009 and September 30, 2009) to reflect the revised value of this Liability.

A-14

Fair value at measurement dates during the period from Warrants’ issuances at May 10, 2009, May 18, 2009 and May 21, 2009 to December 31, 2009, were estimated using the following assumptions:


Underlying price per share	$0.56 - $2.54
Exercise price per share	$1.10 – $1.65
Risk-free interest rate	0.19% - 2.67%
Expected holding period	0.122 - 5.50 years
Expected volatility	94.99% – 226.46%
Expected dividend yield	None

The significant assumptions using the Monte Carlo Simulation approach for valuation of the Warrants are:

A-15

The Company only has one product that is FDA approved;

The Company will have to perform additional clinical trials for FDA approval of its flagship product;

Industry and market conditions continue to include a global market recession, adding risk to any transaction;

Available capital for a potential buyer in a cash transaction continues to be limited;

The nature of a life sciences company is heavily dependent on future funding and high fixed costs, including Research & Development;

The Company's Rights Agreement makes it less attractive to a potential buyer.

With the above factors utilized in analysis of the likelihood of the Put's potential Liability, the Company estimated the range of probabilities related to a Put right being triggered as:

Range of Probability	Probability
Low	0.5%
Medium	1.0%
High	5.0%

The Monte Carlo Simulation incorporated a 5.0% probability of a Fundamental Transaction.

As a result of the corrections in the valuation of the Liabilities as of December 31, 2009 described above, the Company has restated its consolidated financial statements in this amended report as follows:

NOTES:

(a)	The total initial estimated fair value of the Liability related to the Warrants was $17,359,000 at the date of their issuance in May 2009. In order to record this Liability, an adjustment will be made to decrease Additional Paid-In Capital and increase Liabilities by $17,359,000.

(b)

In May 2009 and June 2009, some of these Warrants were exercised resulting in total non-cash losses of $3,675,000. Prior to each exercise, the individual Warrant’s fair value was revalued. The revaluation adjustments was made to increase the above mentioned Warrants’ Liability of $17,359,000 by the related $3,675,000 loss and then, upon exercise, reduce the Warrants’ Liability value by $7,417,000 for the exercised Warrants.

(c)

None of the above issues from this non-cash adjustment affected the Company’s revenues, operating expenses, liquidity or cash flows from past, nor should they affect future operations, except in the highly unlikely event that a Put right is triggered under the Warrants.
