NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Basis Of Presentation

The consolidated financial statements include the financial statements of Hemispherx Biopharma, Inc. and its wholly-owned subsidiaries. The Company has three domestic subsidiaries BioPro Corp., BioAegean Corp. and Core Biotech Corp., all of which are incorporated in Delaware and are dormant. The Company’s foreign subsidiary, Hemispherx Biopharma Europe N.V./S.A., established in Belgium in 1998, has minimal activity. All significant intercompany balances and transactions have been eliminated in consolidation.

In the opinion of Management, all adjustments necessary for a fair presentation of such consolidated financial statements have been included. Such adjustments consist of normal recurring items. Interim results are not necessarily indicative of results for a full year.

The interim consolidated financial statements and notes thereto are presented as permitted by the Securities and Exchange Commission (“SEC”), and do not contain certain information which will be included in our annual consolidated financial statements and notes thereto.

These consolidated financial statements should be read in conjunction with our consolidated financial statements for the year ended December 31, 2010, contained in our Annual Report on Form 10-K for the year ended December 31, 2010.

Note 2: Net Loss Per Share

Basic and diluted net loss per share is computed using the weighted average number of shares of common stock outstanding during the period. Equivalent common shares, consisting of stock options and warrants including the Company’s convertible debentures, which amounted to 52,641,984 and 53,244,248 shares, are excluded from the calculation of diluted net loss per share for the six months ended June 30, 2010 and 2011, respectively, since their effect is antidilutive.

Note 3: Equity Based Compensation

The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton option valuation model. Expected volatility is based on the historical volatility of the price of the Company’s stock. The risk-free interest rate is based on U.S. Treasury issues with a term equal to the expected life of the option. The Company uses historical data to estimate expected dividend yield, expected life and forfeiture rates. The fair values of the options granted, were estimated based on the following weighted average assumptions:

	Six Months Ended June 30,
	2010	2011
Risk-free interest rate	1.02% - 2.03%	1.40% - 2.24%
Expected dividend yield	-	-
Expected lives	5.0 yrs.	5.0 years
Expected volatility	109.72% - 110.01%	104.29% - 104.47%
Weighted average grant date fair value per options and warrants issued	$0.47 per option for 860,000 options	$0.32 per option for 430,000 options

Note 4: Inventories

The Company uses the lower of first-in, first-out (“FIFO”) cost or market method of accounting for inventory.

Inventories consist of the following:	(in thousands)
	December 31,			June 30,
	2010			2011
Inventory work-in-process	$	864		$	787
Production		373			179

	$	787		$	966

The production of Alferon N Injection® from the Work-In-Progress Inventory continued through January 2011 with its conversion into Active Pharmaceutical Ingredient (“API”) and is near completion for the related Final Lot Release Test. To formulate, fill and finish Alferon N Injection® Drug Product, we require a U.S. Food and Drug Administration (“FDA”) approved third party Contract Manufacturing Organization (“CMO”). In June 2011, our designated CMO reported to us that they had received an FDA 483 form that identified production issues that needed to be addressed prior to resumption of production. As a result, we have deemed it necessary to seek an alternative CMO to undertake the Formulation Fill and Finish process. When a new CMO is selected, it will be necessary to conduct tests to qualify the new CMO. The supporting data must then be submitted to the FDA, and the CMO approved by FDA, prior to our being able to commercially sell Alferon N Injection®. We estimate that commercial sales of Alferon N Injection® will not resume until early 2012.

Note 5: Marketable Securities

Marketable securities consist of fixed income securities with remaining maturities of greater than three months at the date of purchase, debt securities and equity securities. As of June 30, 2011, it was determined that some of the Marketable Securities had other than temporary impairments for a total of approximately $179,000 in loss, which has been included with interest and other income for reporting purposes. At June 30, 2011, all securities were classified as available for sale investments and $21,991,000 were measured as Level 1 instruments and $15,683,000 were measured as level 2 instruments of the fair value measurements standard (see Note 10: Fair Value).

Unrealized losses from fixed-income securities are primarily attributable to changes in interest rates. Unrealized losses from domestic and international equities are due to market price movements. Management does not believe any remaining losses represent other than temporary impairment based on our evaluation of available evidence as of June 30, 2011.

Note 8: Construction in Progress

Utilizing our Board of Directors approval of up to $4.4 million for full engineering studies, capital improvements, system upgrades and introduction of building management systems to enhance production of Alferon®, the project has progressed to the construction phase. Construction in progress consists of accumulated costs for the construction and installation of capital improvements and process equipment within the Company’s New Brunswick, New Jersey facility until the assets are placed into service. As of December 31, 2010, construction in progress was $485,000 as compared to $802,000 as of June 30, 2011. The primary purpose of this upgrade is to significantly increase our production capacity for Alferon® API. As expected in any construction project, we are experiencing some delay due to permit issues, demolition concerns and design revisions. We have used this time to pursue cost savings where possible, including locating and acquiring equipment from major U.S. pharmaceutical manufacturers that have recently curtailed or eliminated certain manufacturing activities or plants. As a result, we have estimated a cost savings of approximately $800,000 to date for the project as compared to acquiring the equipment directly from the original manufacturer.

Note 9: Stockholders’ Equity

The Equity Compensation Plan effective May 1, 2004, authorized the grant of non-qualified and incentive stock options, stock appreciation rights, restricted stock and other stock awards. A maximum of 8,000,000 shares of common stock is reserved for potential issuance pursuant to awards under the Equity Plan of 2004. Unless sooner terminated, the Equity Compensation Plan of 2004 will continue in effect for a period of 10 years from its effective date. Prior to June 30, 2011, the Company effectively exhausted this plan by previously issuing an aggregate of 7,989,981 shares, stock options and warrants to vendors, Board Members, Directors and consultants under the 2004 Equity Compensation Plan. The shares had prices ranging from $0.35 to $0.89 based on the NYSE Amex closing price. The stock options had various exercise prices ranging from $1.30 to $6.00, had terms of five to ten years and vesting immediately to three years.

The Equity Incentive Plan of 2007, effective June 20, 2007, authorizes the grant of non-qualified and incentive stock options, stock appreciation rights, restricted stock and other stock awards. A maximum of 9,000,000 shares of common stock is reserved for potential issuance pursuant to awards under the Equity Incentive Plan of 2007. Unless sooner terminated, the Equity Incentive Plan of 2007 will continue in effect for a period of 10 years from its effective date. The Company issued to vendors, Board Members, Directors and consultants, shares, stock options, warrants and “Incentive Rights” under the Employee Wages or Hours Reduction Program. Prior to June 30, 2011, the Company effectively exhausted this plan by previously issuing an aggregate of 8,980,374 shares and shares issuable upon exercise/conversion of the foregoing securities. The aggregate shares to vendors, Board Members, Directors and consultants had prices ranging from $0.32 to $2.54 based on the NYSE Amex closing price. The stock options had various exercise prices ranging from $0.72 to $3.05, terms of ten years and vesting over varying periods.

The Company utilized the Black-Scholes-Merton Pricing Model to arrive at the fair value of the stock options which had been issued during the six months ended June 30, 2011 and accordingly recorded approximately $138,000 as equity based compensation for these issuances during this period. The stock options are generally priced at a premium of 110% of the stock’s NYSE Amex Closing Price on the effective date of issuance or contractual agreement with vesting immediate upon grant.

The Equity Incentive Plan of 2009, effective June 24, 2009, authorizes the grant of non-qualified and incentive stock options, stock appreciation rights, restricted stock and other stock awards. A maximum of 15,000,000 shares of common stock is reserved for potential issuance pursuant to awards under the Equity Incentive Plan of 2009. Unless sooner terminated, the Equity Incentive Plan of 2009 will continue in effect for a period of 10 years from its effective date. As of June 30, 2011, the Company issued 4,052,268 securities to Directors and consultants consisting of an aggregate 738,808 shares of common stock and options to purchase 3,313,460 shares. The shares issued to consultants had prices ranging from $0.40 to $0.68 based on the NYSE Amex closing price.

-14-

The aggregate stock options had various exercise prices ranging from $0.41 to $2.81, had terms of ten years and vested immediately upon grant.

Pursuant to a May 28, 2010 Equity Distribution Agreement (the “Agreement”) with Maxim Group LLC (“Maxim”), the Company established an At-The-Market (“ATM”) Equity Program pursuant to which the Company may sell up to 32,000,000 shares of its Common Stock from time to time through Maxim as its sales agent (the “Agent”). Under the Agreement, the Agent is entitled to a commission at a fixed commission rate of 4.0% of the gross sales price per Share sold, up to aggregate gross proceeds of $10,000,000, and, thereafter, at a fixed commission rate of 3.0% of the gross sales price per Share sold. The Company has no obligation to sell any shares under this program, and may at any time terminate the Agreement. During the six months ended June 30, 2011, the Company sold no shares through this program and received no net cash proceeds. As of June 30, 2011, the Company has sold an aggregate of 520,000 shares that resulted in net cash proceeds of approximately $293,000 and commissions paid to Maxim of approximately $12,000.

The proceeds from this financing have been used to fund infrastructure growth including manufacturing, regulatory compliance and market development.

Note 10: Fair Value

The Company is required under U.S. Generally Accepted Accounting Principles (“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.

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.

-15-

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 June 30, 2011, was estimated using the following assumptions:

Underlying price per share	$0.39
Exercise price per share	$1.31-$1.65
Risk-free interest rate	0.77%-1.00%
Expected holding period	2.88-3.38 yrs.
Expected volatility	115.71%-120.55%
Expected dividend yield	None

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:

-16-

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; 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 has consistently incorporated a 5.0% probability of a Fundamental Transaction from the initial valuation of May 2009 through June 30, 2011.

(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.

While the assumptions remain consistent from period to period (e.g., utilizing historical stock prices), the numbers input change from period to period (e.g., the actual historical prices input for the relevant period). The carrying amount and estimated fair value of the above warrants was approximately $1,860,000 at June 30, 2011. There were no other financial instruments at June 30, 2011.

-17-

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 for those warrants with a cash settlement feature at fair value. As of June 30, 2011, the Company had no derivative assets or liabilities.

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 quoted 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 June 30, 2011, the Company has classified the Warrants with cash settlement features as Level 3. Management evaluates a variety of inputs and then estimates fair value based on those inputs. As discussed above, the Company utilized the Monte Carlo Simulation Model in valuing these Warrants.

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 June 30, 2011:

	Total		Level 1		Level 2		Level 3
Assets
Marketable Securities	$	37,674,000	$	21,991,000	$	15,683,000	$	0
Liabilities
Warrants		1,860,000		0		0		1,860,000
Total	$	39,534,000	$	21,991,000	$	15,683,000	$	1,860,000

The changes in Level 3 Liabilities measured at fair value on a recurring basis are summarized as follows:

	Fair Value of Redeemable
	Warrants
	(in thousands)
	2010			2011
Balance at January 1	$	3,684		$	2,805
Fair value adjustment at March 31		1,336			(302	)
Balance March 31	$	5,020		$	2,503
Fair value adjustment at June 30		(2,260	)		(643	)
Balance June 30	$	2,760		$	1,860

NOTE 11: Cash And Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

NOTE 12: Recent Accounting Pronouncements

In 2011, the Financial Accounting Standards Board (“FASB”) had published FASB Accounting Standards Updates 2011-01 & 02, related to the accounting treatment of Receivables that became effective on June 15, 2011, along with Updates 2011-03, 04 & 05, that are effective for fiscal years beginning after December 15, 2011. The adoption of these five published FASB Accounting Standards Updates by their respective effective dates have been deemed by Management to have no material effect on the Company’s financial statements for the six months ended June 30, 2011.

NOTE 13: Funds Received From Sale Of Income Tax Net Operating Losses

As of December 31, 2010, the Company had approximately $102,000,000 of federal net operating loss carryforwards (expiring in the years 2011 through 2030) available to offset future federal taxable income. The Company also had approximately $37,000,000 of Pennsylvania state net operating loss carryforwards (expiring in the years 2018 through 2030) and approximately $38,000,000 of New Jersey state net operating loss carry forwards (expiring in the years 2011 through 2017) available to offset future state taxable income. In February 2011, the Company effectively sold $28,000,000 of its New Jersey state net operating loss carry forwards (for the years 2003 through 2008) for $2,271,928. The utilization of certain state net operating loss carryforwards may be subject to annual limitations.

NOTE 14: Subsequent Events

The Company evaluated subsequent events through the date on which these financial statements were issued. A Board approved “Margin Account” was established with Wells Fargo Advisors for which the proceeds of the indebtedness are restricted to effectively serving the Company as a line of credit to finance the capital improvements underway at the New Brunswick, New Jersey Manufacturing facility (see Note 8: Construction in Progress). In order to establish this Margin Account on July 26, 2011, with a dollar value of $4 million, the Company has pledged, restricted from sale and segregated approximately $8 million of its Marketable Securities in order to maintain a two to one ratio of approved debt to collateral. With the exception of collateral requirements, the Company maintains all the rights and benefits of ownership including receipt of interest, dividends or proceeds from the securities. While this Margin Account has no material establishment or maintenance fees, it currently carries an effective interest rate of approximately 3% per annum, based on the prevailing “Wells Fargo Base Rate” less 2.75%, applied against the “Margin Debit Balance” (i.e., those funds withdrawn and outstanding). Otherwise, the Company has determined that no other subsequent event constituted a matter that required disclosure or adjustment to the financial statements for the six months ended June 30, 2011.

Overview

General

We are a specialty pharmaceutical company based in Philadelphia, Pennsylvania and engaged in the clinical development of new drug therapies based on natural immune system enhancing technologies for the treatment of viral and immune based chronic disorders. We were founded in the early 1970s doing contract research for the National Institutes of Health. Since that time, we have established a strong foundation of laboratory, pre-clinical and clinical data with respect to the development of natural interferon and nucleic acids to enhance the natural antiviral defense system of the human body and to aid the development of therapeutic products for the treatment of certain chronic diseases. We have three domestic subsidiaries BioPro Corp., BioAegean Corp., and Core BioTech Corp., all of which are incorporated in Delaware and are dormant. Our foreign subsidiary is Hemispherx Biopharma Europe N.V./S.A. established in Belgium in 1998, which has minimal activity. All significant intercompany balances and transactions have been eliminated in consolidation.

Our current strategic focus is derived from four applications of our two core pharmaceutical technology platforms Ampligen® and Alferon N Injection®. The commercial focus for Ampligen® includes application as a treatment for Chronic Fatigue Syndrome (“CFS”) and as a vaccine enhancer (adjuvant) for both therapeutic and preventative vaccine development. Alferon N Injection® is a Food and Drug Administration (“FDA”) approved product with an indication for refractory or recurring genital warts and currently under a clinic study targeting influenza. Alferon® LDO (Low Dose Oral) is a formulation currently under development targeting influenza.

-20-

We own and operate a 43,000 sq. ft. FDA licensed manufacturing facility in New Brunswick, New Jersey that was primarily designed to produce Alferon®. On September 16, 2009, our Board of Directors approved up to $4.4 million for full engineering studies, capital improvements, system upgrades and introduction of building management systems to enhance production of three products: Alferon N Injection®, Alferon® LDO and Ampligen®. We outsource certain components of our research and development, manufacturing, marketing and distribution while maintaining control over the entire process through our quality assurance group and our clinical monitoring group.

Ampligen®

Ampligen® is an experimental drug currently undergoing clinical development for the treatment of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (“ME/CFS”). Over its developmental history, Ampligen® has received various designations, including Orphan Drug Product Designation (FDA), Treatment Investigational New Drug (“IND”) (e.g., treatment investigational new drugs, or “Emergency” or “Compassionate” use authorization) with Cost Recovery Authorization (FDA) and “promising” clinical outcome recognition based on the evaluation of certain summary clinical reports (“AHRQ” or Agency for Healthcare Research and Quality). Ampligen® represents the first drug in the class of large (macromolecular) RNA (nucleic acid) molecules to apply for New Drug Application (“NDA”) review. Based on the results of published, peer reviewed pre-clinical studies and clinical trials, we believe that Ampligen® may have broad-spectrum anti-viral and anti-cancer properties. Over 1,000 patients have participated in the Ampligen® clinical trials representing the administration of more than 90,000 doses of this drug.

On November 25, 2009, we received a Complete Response Letter (“CRL”) from the FDA which described specific additional recommendations related to the Ampligen® NDA. In accordance with its 2008 Complete Response procedure, the FDA reviewers determined that they could not approve the application in its present form and provided specific recommendations to address the outstanding issues. Most notably, the FDA stated that the two primary clinical studies submitted with the NDA did not provide credible evidence of efficacy of Ampligen® and recommended at least one additional clinical study which shows convincing effect and confirms safety in the target population. The FDA indicated that the additional study should be of sufficient size and sufficient duration (six months) and include appropriate monitoring to rule out the generation of autoimmune disease. In addition, patients in the study should be on more than one dose regimen, including at least 300 patients on dose regimens intended for marketing. In designing and implementing these additional trials, we believe that it would be very valuable to first have the capability of utilizing a reliable diagnostic test to better identify potential participants. We are therefore pursuing efforts to identify and validate such a test (see “Progress In Search For CFS Test” below). In the Non-Clinical area, the FDA recommended among other things that we complete rodent carcinogenicity studies in two species.

We estimate that it could take approximately 18 months to three years to complete an Ampligen® clinical study from the date of our commencement of the study for resubmission to the FDA under the industry norm of three to six months to initiate the study, one to two years to accrue and test patients, three to six months to close-out the study and file the necessary documents with the FDA. The actual duration to complete the clinical study may be different based on the final design of an accepted FDA clinical Phase III study, availability of participants, clinical sites, when the study commences and any other factors that could impact the implementation of the study, analysis of results, or requirements of the FDA and other governmental organizations.

-21-

Additionally, we estimate that the approximate cost to undertake the Ampligen® Phase III clinical study could range from $12,000 to $18,500 per each of the 600 participating patients, for an estimated range of total incremental costs of $7,200,000 to $11,100,000. Our estimate is based on the belief that our experience from the prior Phase III study and established teams (e.g., Medical, Data Processing, Clinical Monitors, Statisticians, Medical Reporting) along with existing inventory and investigational protocol, could produce financial efficiencies. We believe that these efficiencies could permit our costs of undertaking a Phase III CFS study to be discounted as compared to a potential $28,500 per patient cost approximated as an industry average for running a Phase III study from scratch, as estimated and adjusted for inflation, utilizing data from the business intelligence firm Cutting Edge Information. The actual costs of a Phase III investigation study for CFS may differ based on final design of an accepted FDA Phase III clinical study, prevailing costs to undertake clinical studies, qualification and access to CFS patients, insurance and government requirements along with other potential costs or reimbursements unknown at this time.

Aside from the foregoing, we cannot determine or estimate what diagnostic test or tests may eventually be used to identify potential participants, additional studies and/or additional testing or information that the FDA may require. Accordingly, as of this time, we are unable to estimate the nature, timing, costs and necessary efforts to obtain FDA clearance, the anticipated completion dates or whether we will obtain FDA clearance.

In December 2010, the FDA granted us a one year extension to file a response to the CRL based on the submission of new data concerning the potential viral etiology of CFS. We are presently enlarging our open label CFS clinical trials in the USA in an attempt obtain more data on possible interrelationships between CFS and XMRV (see below) and the therapeutic response to Ampligen®. The Company is diligently working to address the diagnostic challenges related to CFS.

Progress In Search For CFS Test

As stated on the CDC website, diagnosing CFS can be complicated by a number of factors:

There is no diagnostic laboratory test or biomarker for CFS;

Fatigue and other symptoms of CFS are common to many illnesses;

CFS is an invisible illness and many patients don't look sick;

The illness has a pattern of remission and relapse;

Symptoms vary from person to person in type, number and severity.

These factors have contributed to a very low diagnosis rate in which of the up to four million Americans estimated to have CFS, less than 20 percent of those stricken are being properly diagnosed. Because currently there is no FDA approved blood test, brain scan or other lab test to diagnose CFS, it's a diagnosis of exclusion. If a patient has had six or more consecutive months of severe fatigue that is reported to be unrelieved by sufficient bed rest and that is accompanied by nonspecific symptoms, including flu-like symptoms, generalized pain and memory problems, the patient may have CFS.

In the October 8, 2009 issue of Science Express, a consortium of researchers from the Whittemore Peterson Institute for Neuro-Immune Disease, a Nevada non-profit corporation (“WPI”), the National Cancer Institute and the Cleveland Clinic reported their observation of a new retrovirus, xenotropic murine leukemia related virus (“XMRV”) in the blood cells of 67% of CFS patients and 3.7% in healthy control subjects. They also observed that the infectious virus was greater than 99% identical to that previously detected in prostate cancer. Retrospective analyses of patient samples from the completed Phase III trial of Ampligen® in potential treatment of CFS continues in collaboration with WPI. On July 20, 2011, we renewed our agreement with WPI, effective February 1, 2011, whereby they continue to evaluate Hemispherx’ patient samples for XMRV using WPI’s flow cytometry assay. This renewed agreement terminates when WPI concludes the assigned work, or at the end of a term of twelve months commencing on the effective date, whichever is first to occur.

-22-

In May 1997, the FDA approved an open-label treatment protocol, (“AMP 511”), allowing patient access to Ampligen® for treatment. The data collected from the AMP 511 protocol provides safety data on the use of Ampligen® in patients to identify adverse events that occur in a patient to determine if it is related to the drug being tested or other health problems identified in trial participants. We have recently amended this protocol to include testing patient samples for XMRV in order to observe a possible relationship between a patient’s response to Ampligen® and XMRV viral activity. The revised protocol was submitted to the FDA for review in May 2011, and no comments have been received, thereby allowing us to implement the revised protocol.

On June 2, 2011, the U.S. Department of Health and Human Services’ National Institutes of Health (“NIH”) released a report entitled “Origins of XMRV deciphered, undermining claims for a role in human disease” which stated the XMRV virus is unlikely to be responsible for either prostate cancer or Chronic Fatigue Syndrome, rather that the apparent association of XMRV with human disease was most likely due to the contamination of the blood samples.

However in June 2011, the NIH updated two pages on its website, affirming its plan to continue with two multicenter studies in which the Whittemore Peterson Institute and other laboratories are participating. As a result, the NIH appears prepared to continue to fund studies to determine whether results of recent studies can be replicated. We believe that these studies may provide further perspective on the design of an additional confirmatory Phase III study in this disorder.

On March 2, 2011, we jointly filed a provisional United States patent application on a blood test for CFS with Chronix Biomedical ("Chronix"). This experimental approach utilized in the Chronix test analyzes fragments of DNA often released into the bloodstream during the process of apoptosis or programmed cell death to measure alterations in specific regions of the chromosome, which can be detected as distinctive "signatures" in cell-free blood-borne DNA. The patient-unique signatures captured by Chronix’ technology may prove useful as a companion diagnostic and to provide information about the disease process to help pharmaceutical companies select the most efficacious drug candidates. Hemispherx and Chronix are currently collaborating in the utilization of this process towards the development of a diagnostic tool for CFS.

Alferon N Injection®

Alferon N Injection® is the registered trademark for our injectable formulation of natural alpha interferon, which is approved by the FDA in 1989 for the treatment of certain categories of genital warts. Alferon® is the only natural-source, multi-species alpha interferon currently approved for sale in the U.S. for the intralesional (within lesions) treatment of refractory (resistant to other treatment) or recurring external genital warts in patients 18 years of age or older.

Alferon N Injection® [Interferon alfa-n3 (human leukocyte derived)] is a highly purified, natural-source, glycosylated, multi-species alpha interferon product. There are essentially no antibodies observed against natural interferon to date and the product has a relatively low side-effect profile.

Commercial sales of Alferon N Injection® were halted in March 2008 when our finished goods inventory expired. The production of Alferon N Injection® from the Work-In-Progress Inventory continued into January 2011 with its conversion into Active Pharmaceutical Ingredient (“API”) and is near completion for the related Final Lot Release Test. To formulate, fill and finish Alferon N Injection® Drug Product, we require a U.S. Food and Drug Administration (“FDA”) approved third party Contract Manufacturing Organization (“CMO”). In June 2011, our designated CMO reported to us that they had received an FDA 483 form that identified production issues that needed to be addressed prior to resumption of production. As a result, we have deemed it necessary to seek an alternative CMO to undertake the Formulation Fill and Finish process. When a new CMO is selected, it will be necessary to conduct tests to qualify the new CMO. The supporting data must then be submitted to the FDA, and the CMO approved by FDA, prior to our being able to commercially sell Alferon N Injection®. We estimate that commercial sales of Alferon N Injection® will not resume until early 2012.

Alferon® Low Dose Oral (LDO)

Alferon® LDO [Low Dose Oral Interferon Alfa-n3 (Human Leukocyte Derived)] is an experimental low-dose, oral liquid formulation of Natural Alpha Interferon and like Alferon N Injection® should not cause antibody formation, which is a problem with recombinant interferon. It is an experimental immunotherapeutic believed to work by stimulating an immune cascade response in the cells of the mouth and throat, enabling it to bolster systemic immune response through the entire body by absorption through the oral mucosa. Oral interferon could be economically feasible for patients and logistically manageable in development programs in third-world countries primarily affected by influenza and other emerging viruses. Oral administration of Alferon® LDO, with its anticipated affordability, low toxicity, no production of antibodies, and broad range of potential bioactivity, could be a breakthrough treatment or prevention for viral diseases.

On December 22, 2010, the FDA approved a Phase II, double-blind, adaptive-design, randomized, placebo-controlled, dose-ranging study of Alferon® LDO for the prophylaxis and treatment of seasonal and pandemic influenza of more than 200 subjects. As an element of our early stage preparation for the Phase II Study, we are conducting a confirmatory study for systemic effects in peripheral blood leukocytes following treatment with Alferon® LDO. The outcome of this confirmatory study will allow us to better evaluate the potential effectiveness of this product and determine the cost/benefit of proceeding with this study of seasonal and pandemic influenza.

Other Viral Diseases

Ampligen® as a mucosal adjuvant with vaccine had been studied at Japan’s National Institute of Infectious Disease (“NIID”) and at Biken (the for profit operational arm of the Foundation for Microbial Diseases of Osaka University). Investigators from Japan’s NIID had conducted studies in animals that suggested that Ampligen® could stimulate a sufficiently broad immune response to provide cross-protection against a range of virus genetic types, including H5N1 and derivative clades. Japan’s Council for Science & Technology Policy (“CSTP”), a cabinet level position, awarded funds from Japan’s CSTP to advance research with influenza vaccines utilizing Ampligen®.

A Material Evaluation Agreement (“MEA”) regarding Ampligen® with Biken that was initiated on August 19, 2009, effectively expired on September 1, 2010. Pursuant to the MEA, we supplied Biken with proprietary information related to Ampligen® and Biken purchased Ampligen® from us for use solely in connection with evaluating Ampligen® as a candidate for adjuvant incorporated into potential influenza virus vaccines in the form of intranasal mucosal administration, including conducting further animal studies of intranasal prototype vaccines containing antigens from various influenza sub-types, including H5N1, H1N1, H3N2 and B (the “Evaluation Program”). As previously reported, Hemispherx and Biken had been in correspondence concerning both the possibility of extending or replacing the expired agreement and reconciling the interpretation of experimental results. However, until such time that a new agreement could be established, no collaboration would be undertaken between the respective companies.

-24-

In April 2011, we received correspondence from Biken confirming that the MEA had expired without completion of the Evaluation Program along with their intension not to extend or replace the expired MEA with another agreement. Biken noted in that correspondence that it previously had concluded that “it was possible that Ampligen® would not satisfy the requirements for safety as an adjuvant for influenza vaccines” in Japan and that, after rechecking Hemispherx’ basis for disagreement with that finding, it concluded that it could not reconcile the differences between Hemispherx’ and its interpretation of experimental results regarding the evaluation of Ampligen® as a candidate adjuvant in influenza vaccines. Biken’s primary concern was related to a single intravenous high dose study in rats that resulted in an apparent toxicity when doses of Ampligen® were combined with a whole viron influenza vaccine and Carboxyl Vinyl Polymer (“CVP”) or CVP alone. Additionally in both cases of Ampligen® being combined with other product(s), the dosage utilized was several hundred times higher than the intended dosage for humans by body weight and delivered intravenously, rather than the prescribed mucosal (nasal) method. More specifically, we communicated the following points to refute Biken’s interpretation of Ampligen® safety data:

The safety of Ampligen® has been demonstrated by the large body of safety data in humans and in relevant pre-clinical models that were generated to support Hemispherx’ NDA for CFS, which was filed with the FDA;

The single unfavorable rat toxicity study contained in the Biken report must be considered in the context of the rest of safety and efficacy data generated with Ampligen® and we believe that evidence indicates that the results were generated due to flaws in material handling and compounding;

Hemispherx demonstrated by photographs and other evidences that the toxicity observed at Biken was due to aggregation caused by the CVP additive deployed by Biken to increase attachment of the vaccine/Ampligen® mixture to the nasal mucosa. Numerous experiments performed by the NIID indicated that in both rodents and primates that the additive was unnecessary to achieve the desired antiviral/vaccine enhancement effects of Ampligen® and

There are large anomalies between the efficacy data presented in the internal Biken report as compared to the results obtained by Dr. Hasegawa, and thereafter published in peer reviewed articles.

As a result of Biken’s intension not to extend or replace the MEA or complete the related Evaluation Program, we have concluded that our association with Biken has come to a conclusion with no expected future association.

Dr. Hideki Hasegawa, M.D., Ph.D., Chief of Laboratory of Infectious Disease Pathology for the Department of Pathology for the NIID, undertook studies in 2009, continuing into 2010, that focused on mucosal immunity and the inherent advantages of a vigorous immune response to respiratory pathogens. Dr. Hasegawa has published data that the formulation of pandemic vaccine mixed with Ampligen® increases immuno-genicity and may demonstrate cross protection against mutated strains. Dr. Hasegawa has expressed a desire to continue the preclinical development, and as such, he continues to organize and participate in meetings with other qualified corporate vaccine partners in Japan who have intranasal vaccines under development along with necessary facilities to test, develop and commercialize the vaccine enhancement utilizing Ampligen® in an attempt to achieve cross-protection against pandemic strains in a commercial environment.

-25-

In July 2011, we received FDA authorization to proceed with the initiation of a new clinical trial of intranasal Ampligen® to be used in conjunction with commercially approved seasonal influenza vaccine. This study is similar to the initial studies of influenza application conducted at Japan’s NIID noted above. The primary objective of this study is to evaluate the safety of three cycles of intranasal Ampligen® administered three days following each intranasal dose of seasonal influenza vaccine. Secondary objectives of this study include evaluation of various immune responses to the trivalent seasonal influenza vaccine administered intranasally with and without Ampligen®.

In April 2010, we began the process to undertake a clinical study with Max Neeman International, a leading and large clinical research organization in India. This collaborative clinical research effort is intended to utilize Alferon N Injection® for treatment of seriously ill patients hospitalized with either seasonal influenza or pandemic influenza. The Indian site selection process was initiated and we obtained approval to begin the study from the Indian Drugs Controller General on July 13, 2010. We began enrolling subjects in September 2010 and continue to enroll subjects through the current monsoon season, which has a reduced frequency of influenza among the population. As of June 30, 2011, we have five operational Clinical Investigative Sites, with the potential to add additional sites, and sixteen patients have completed the study. Our Study has progressed at a rate slower than originally projected with difficulties encountered in the process of screening for subjects who were stricken only with influenza. In an attempt to expedite the process to qualify study subjects, we have added a second “point of care” screening test which continues to be implemented at the sites as we prepare for the upcoming flu season. It is our objective to qualify and enroll sixty patients for the study.

In June 2011, we entered into a Material Transfer and Research Agreement with the University of Pennsylvania’s School of Medicine to provide Ampligen® for testing as a vaccine adjuvant in a human clinical study in ovarian cancer. This study is a Phase I/II randomized clinical trial for subjects with recurring ovarian, fallopian tube or primary peritoneal cancer to determine the feasibility and safety as well as immunogenicity of a vaccine comprised of autologous oxidized tumor cell lysate (“OC-L”) administered by intradermal/subcutaneous injection in combination with intravenous Ampligen®. The OC-L vaccine is an experimental cancer immunotherapy under development by the University of Pennsylvania. This study represents the first use of Ampligen® as a cancer vaccine adjuvant in a randomized clinical study with and without Ampligen®.

In July 2011, a new United States Patent was granted for the use of Ampligen® as a vaccine adjuvant for use with seasonal influenza vaccine to induce an enhanced immune response against H5N1 avian influenza. The patent describes a method using intranasal administration of Ampligen® along with a seasonal influenza vaccine to enhance an immune response against a H5N1 avian influenza infection compared to the administration of seasonal influenza vaccine alone.

Critical Accounting Policies

There have been no material changes in our critical accounting policies and estimates from those disclosed in Part I; Item 2: “Management's Discussion and Analysis of Financial Condition and Results of Operations; Critical Accounting Policies” contained in our amended and restated Annual Report on Form 10-K for the year ended December 31, 2010.

RESULTS OF OPERATIONS

Three months ended June 30, 2011 versus three months ended June 30, 2010

Net Loss

Our net loss was approximately $2,294,000 for the three months ended June 30, 2011, an increase of $878,000 or 62% when compared to the same period in 2010. This increase in loss for these three months was primarily due to the following changes in expense elements:

the revaluation of the Liability related to the Redeemable Warrants resulting in a non-cash gain of $643,000 in 2011 as compared to non-cash net gain of $2,260,000 for the same period in 2010 (See Note 10); offset by:

a decrease in Research and Development costs of approximately $70,000 or 4%;

a decrease in General and Administrative expenses of approximately $332,000 or 19%;

an increase in interest income of $224,000 from funds invested in marketable securities; and

a decrease in Production/Cost of Goods Sold of approximately $124,000 or 38%.

Net loss per share was $(0.01) for the current three month period versus $(0.01) per share for the same period in 2010. The number of shares of our Common Stock outstanding as of June 30, 2011 was 135,458,872.

Revenues

Revenues from our Ampligen® Cost Recovery Program decreased $5,000 or 12% for the second quarter of 2011 as compared to the same time period of 2010. Although the number of patients increased 21% in the three months ended June 30, 2011 there were a number of shipments to patients on compassionate care which resulted in a lower revenue for the period. As previously stated, we have no Alferon N Injection® product to commercially sell at this time and all revenue was generated from the Ampligen® cost recovery clinical treatment programs.

-27-

Production/Cost of Goods Sold

Production/Cost of Goods Sold was approximately $204,000 and $328,000, respectively, for the three months ended June 30, 2011 and 2010. This decrease of $124,000 or 38% was primarily due to the lower cost to maintain existing Alferon N Injection® and Ampligen® inventory including storage, stability testing, transport and reporting costs.

Research and Development Costs

Overall Research and Development (“R&D”) costs for the three months ended June 30, 2011 were approximately $1,624,000 as compared to $1,694,000 for the same period a year ago reflecting a slight decrease of $70,000 or 4%. The R&D efforts during this three month period in 2011 included clinical costs along with research and development costs related to Alferon® LDO as we undertake a confirmatory study, which will help us to further evaluate the potential effectiveness of this product and determine the cost/benefit of proceeding with this study of seasonal and pandemic influenza.

General and Administrative Expenses

General and Administrative (“G&A”) expenses for the three months ended June 30, 2011 and 2010 were approximately $1,456,000 and $1,788,000, respectively, reflecting a decrease of $332,000 or 19%. The lower G&A expenses in 2011 consisted primarily of a decrease of $215,000 in legal fees due to settlement in 2010 of various legal proceedings and lower stock compensation expense of $249,000 for stock options issued due to the lower market value of the Company stock in 2011.

Interest and Other Income

Interest and other income for the three months ended June 30, 2011 and 2010 was approximately $317,000 and $93,000, respectively, representing an increase of $224,000 or 241%. The primary cause for the increase of interest income in 2011 was the investment into a diverse portfolio of short and long term investments during 2010. The interest income from these investments is recognized as the investments mature.

Redeemable Warrants

The quarterly fiscal revaluation resulted in non-cash adjustments to the Redeemable Warrants Liability on June 30, 2011 and 2010 of approximately $643,000 and $2,260,000, respectively, representing a decrease of $1,617,000. See “NOTE 10: Fair Value”.

Six months ended June 30, 2011 versus Six months ended June 30, 2010

Net Loss

Our net loss was approximately $3,160,000 for the six months ended June 30, 2011, a decrease of $3,636,000 or 54% when compared to the same period in 2010. This decrease in loss for these six months was primarily due to the following changes in expense elements:

a decrease in Research and Development costs of approximately $426,000 or 12%;

a decrease in General and Administrative expenses of approximately $502,000 or 13%;

-28-

an increase in interest income of $352,000 from funds invested in marketable securities;

the receipt of funds from the sale of State New Jersey tax net operating losses for years 2003 to 2008 for $2,272,000 (See ”NOTE 13: Funds Received From Sale Of Income Tax Net Operating Losses”);

the revaluation of the Liability related to the Redeemable Warrants resulting in a non-cash gain of $944,000 in 2011 as compared to non-cash net gain of $924,000 for the same period in 2010 (See “NOTE 10: Fair Value”); and

a decrease in Production/Cost of Goods Sold expenses of approximately $71,000 or 15%.

Net loss per share was $(0.02) for the current six month period versus $(0.05) per share for the same period in 2010. The number of shares of our Common Stock outstanding as of June 30, 2011 was 135,458,872.

Revenues

Revenues from our Ampligen® Cost Recovery Program increased $5,000 or 7% for the first six months of 2011 as compared to the same time period of 2010 due to a 32% increase in the number of patients participating in the program offset by a number of shipments being made to patients on compassionate care. As previously stated, we have no Alferon N Injection® product to commercially sell at this time and all revenue was generated from the Ampligen® cost recovery clinical treatment programs.

Production/Cost of Goods Sold

Production/Cost of Goods Sold was approximately $397,000 and $468,000, respectively, for the six months ended June 30, 2011 and 2010. This decrease of $71,000 or 15% was primarily due to the lower cost to maintain existing Alferon N Injection® and Ampligen® inventory including storage, stability testing, transport and reporting costs due to our efforts to reduce the production costs of Alferon N Injection® for potential future commercial sales.

Research and Development Costs

Overall Research and Development (“R&D”) costs for the six months ended June 30, 2011 were approximately $3,264,000 as compared to $3,690,000 for the same period a year ago reflecting a decrease of $426,000 or 12%. The primary factors for the decrease in expenses were decreased clinical costs and research and development costs related to Alferon® LDO as we undertake a confirmatory study, which will help us to further evaluate the potential effectiveness of this product and determine the cost/benefit of proceeding with this study of seasonal and pandemic influenza.

-29-

General and Administrative Expenses

General and Administrative (“G&A”) expenses for the six months ended June 30, 2011 and 2010 were approximately $3,255,000 and $3,757,000, respectively, reflecting a decrease of $502,000 or 13%. The lower G&A expenses in 2011 consisted primarily of a decrease in legal fees due to settlement in 2010 of various legal proceedings.

Interest and Other Income

Interest and other income for the six months ended June 30, 2011 and 2010 was approximately $474,000 and $122,000, respectively, representing an increase of $352,000 or 289%. The primary cause for the increase of interest income in 2011 was the investment into a diverse portfolio of short and long term investments during 2010. The interest income from these investments is recognized as the investments mature.

Sale of New Jersey Tax Net Operating Loss

In February 2011, the Company received $2,272,000 from the sale of the State New Jersey tax net operating losses for years 2003 to 2008. (See “NOTE 13: Funds Received From Sale of Income Tax Net Operating Losses”).

Redeemable Warrants

The fiscal revaluation for the six month period resulted in non-cash adjustments to the Redeemable Warrants Liability on June 30, 2011 and 2010 of approximately $944,000 and $924,000, respectively, representing an increase of $20,000. (See “NOTE 10: Fair Value”).

Liquidity and Capital Resources

Cash used in operating activities for the six months ended June 30, 2011 was $4,802,000 compared to $7,388,000 for the same period in 2010, a decrease of $2,586,000 or 35%. This reduction in Cash used was primarily due to lower operating costs and the sale of prior years’ New Jersey Net Operating Loss in 2011. As of December 31, 2010, the Company had approximately $38,000,000 of New Jersey state net operating loss carry forwards (expiring in the years 2011 through 2017) available to offset future state taxable income. In February 2011, the Company effectively sold $28,000,000 of its New Jersey state net operating loss carry forwards (for the years 2003 through 2008) for approximately $2,272,000. Excluding the proceeds from this sale of New Jersey net operating loss carry forwards, Cash used in operating activities for the six months ended June 30, 2011 decreased by approximately $314,000 over the comparable period in 2010. As of June 30, 2011, we had approximately $39,754,000 in Cash, Cash Equivalents and Marketable Securities, or a decrease of approximately $4,600,000 from December 31, 2010.

We have been using the proceeds from our financings with the assistance of Rodman & Renshaw, LLC (“Rodman”) as placement agent and from Fusion Capital Fund II, LLC (“Fusion Capital”) equity financing to fund operating expense and infrastructure growth including preparation for manufacturing, regulatory compliance and market development costs related to the FDA approval process for Ampligen®. During 2009, we raised in the aggregate approximately $33,712,000 in equity financing pursuant to the two Rodman financings in May 2009 along with an aggregate of approximately $28,112,000 in equity financing pursuant to the Fusion Capital Agreement during 2008 and 2009.

-30-

Pursuant to our May 28, 2010 Equity Distribution Agreement (the “Agreement”) with Maxim Group LLC (“Maxim”), we established an At-The-Market (“ATM”) Equity Program pursuant to which we may sell up to 32,000,000 shares of our Common Stock from time to time through Maxim as our sales agent (the “Agent”). Under the Agreement, the Agent is entitled to a commission at a fixed commission rate of 4.0% of the gross sales price per Share sold, up to aggregate gross proceeds of $10,000,000, and, thereafter, at a fixed commission rate of 3.0% of the gross sales price per Share sold. We have no obligation to sell any shares under this program, and may at any time terminate the Agreement. During the six months ended June 30, 2011, we sold no shares through this program and received no net cash proceeds. As of June 30, 2011, we sold an aggregate of 520,000 shares through the ATM that resulted in net cash proceeds of approximately $293,000 and commissions paid to Maxim of approximately $12,000.

There can be no assurances that, if needed, we will be able to raise adequate funds from these or other sources. Our inability to raise such funds, if needed, could have a material adverse effect on our ability to develop our products. Also, we have the ability to curtail discretionary spending, including some research and development activities, if required to conserve cash. Because of our long-term capital requirements, we may seek to access the public equity market whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. We are unable to estimate the amount, timing or nature of future sales of outstanding common stock or instruments convertible into or exercisable for our common stock. Any additional funding may result in significant dilution and could involve the issuance of securities with rights, which are senior to those of existing stockholders. We may also need additional funding earlier than anticipated, and our cash requirements, in general, may vary materially from those now planned, for reasons including, but not limited to, changes in our research and development programs, clinical trials, acquisitions of intellectual property or assets, enhancements to the manufacturing process, competitive and technological advances, the regulatory processes including the commercializing of Ampligen® products or new utilization of Alferon® products.

Our ability to raise additional funds from the sale of equity securities is limited because we only have approximately 31,800,000 shares authorized but unissued and unreserved. We were unable to gather the requisite votes at our annual stockholders’ meeting held in June 2009 to amend our Certificate of Incorporation to increase the number of authorized shares of Common Stock from 200,000,000 to 350,000,000. Since we have not been able to obtain approval to increase the number of authorized shares of Common Stock, the amount of proceeds we may receive from the sale of our remaining Common Stock is limited (See “Part II – OTHER INFORMATION, ITEM 1A. Risk Factors” We may require additional financing which may not be available; the limited number of shares of common stock available for financing or other purposes may hinder our ability to raise additional funding or utilize equity securities for other corporate purposes”).

ITEM 3: Quantitative and Qualitative Disclosures About Market Risk

We had approximately $39,754,000 in Cash, Cash Equivalents and Marketable Securities at June 30, 2011. In prior years, we had invested the excess cash in minimal risk exposure, three to twelve month interest bearing financial instruments. However with the current state of the market and our funds well in excess of our short-term operational needs, our Board has reassessed our cash investment strategy consistent with the following objectives to:

preserve, secure and control capital;

maintain liquidity to meet our operating cash flow requirements; and

maximize return subject to policies and procedures that manage risks with respect to a conservative to moderate investment exposure at high credit quality institutions.

-31-

To accomplish these goals, we entrusted our investible funds through an external investment manager at Wells Fargo Advisors with detailed investment and trading guidelines that are analyzed for compliance on an on-going basis. We have not entered into, and do not expect to enter into, financial instruments for trading or hedging purposes.

Our Cash, Cash Equivalents and Marketable Securities are invested in what Management believes to be high credit quality institutions that primarily consist of:

U.S. Treasury and Government Obligations;

Federal Agency securities sponsored by enterprises and instrumentalities;

Certificates of Deposit;

Money market funds with assets of greater than $1 Billion;

PIMCO Total Return Fund A;

Corporate debt obligations or commercial paper issued by corporations, commercial banks, investment banks and bank holding companies, rated A2/A or better by Moody’s or Standard & Poor’s or P-1 by Moody’s or A-1 or better by Standard & Poor’s; and

Asset-backed securities rated AAA/Aaa, P-1 or A-1+ by Moody’s or Standard & Poor’s.

While Management strives to invest our Cash and Cash Equivalents in high credit quality institutions and securities, our financial instruments are exposed to concentrations of credit risk and market change. Additionally, at times our investments may be in excess of the Federal Deposit Insurance Corporation insurance limit or not qualified for such coverage.

ITEM 4: Controls and Procedures

Our Chairman of the Board (serving as the principal executive officer) and the Chief Financial Officer performed an evaluation of the effectiveness of our disclosure controls and procedures, which have been designed to permit us to effectively identify and timely disclose important information. In designing and evaluating the disclosure controls and procedures, Management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and Management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the controls and procedures were effective as of June 30, 2011 to ensure that material information was accumulated and communicated to our Management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

During the quarter ended June 30, 2011, we have made no change in our internal controls over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Cato Capital, LLC v. Hemispherx Biopharma, Inc., U.S. District Court for the District of Delaware, Case No. 09-549-GMS.

On July 31, 2009, Cato Capital LLC (“Cato”) filed suit asserting that under a November 2008 agreement, the Company owes Cato a placement fee for certain investment transactions. The Complaint seeks damages in the amount of $5,000,000 plus attorneys’ fees. The Company filed an Answer on August 20, 2009. On October 13, 2009, Cato filed a Motion seeking leave to file an Amended Complaint which proposed that Cato be permitted to add The Sage Group as an additional defendant and to bring additional causes of action against the Company arising from the defenses contained in the Answer, and increase the total amount sought to $9,830,000, plus attorneys’ fees and punitive damages. The Company filed a response objecting to the Motion, and also filed a Motion to Disqualify Cato’s Delaware attorneys on basis of a conflict of interest. On September 14, 2010, the Court granted the Company’s Motion to Disqualify Cato’s Delaware attorneys. Also on September 14, 2010, the Court granted Cato’s Motion for Leave to file an Amended Complaint, but specifically indicated that the Company could file a Motion to Dismiss, raising the arguments that the Company had previously made in response to Cato’s Motion for Leave to file an Amended Complaint. On September 16, 2010, Cato filed its Amended Complaint, and on September 30, 2010, the Company filed a Motion to dismiss all the counts of the Amended Complaint against the Company other than the breach of contract count. The timeframe for the Court's disposition of the Motion to Dismiss cannot be ascertained. In addition pursuant to an indemnification responsibility, the Company has also retained counsel to undertake the defense of the Sage Group, and a motion to dismiss has been filed on behalf of the Sage Group seeking to dismiss all claims against the Sage Group. Both motions to dismiss have been fully briefed and are awaiting disposition by the Court. The Parties await a scheduling conference with the Court which will establish Discovery, Motion and other applicable dates.

The Company believes it has meritorious defenses and is vigorously defending against this claim. There is currently no projection as to the likely outcome of the case.

The parties conducted discovery and subsequently, all parties filed Motions for Summary Judgment. By Order dated March 9, 2011, the Court granted the Company's Motion on all the remaining counts of MidSouth's counterclaim, granted Sage's Motion with respect to MidSouth's claims against Sage, and granted MidSouth's Motion with respect to the Company's original Complaint against MidSouth. Costs have been taxed in the Trial Court in favor of the Company and against MidSouth in the amount of $8,631.82, and in favor of Midsouth and against the Company in the amount of $7,916.90.

In April 2011, MidSouth filed a Notice of Appeal from the Order disposing of its claims against the Company and Sage, and the Company filed a Notice of Cross Appeal from the Order granting the Defendants' Motion for Summary Judgment on the original Complaint. The parties' principal briefs have been filed in the Court of Appeals. The Court has not indicated if it will hear oral argument. There is no deadline for the Court to decide the appeals.

Summation.

We have not recorded any loss contingencies as a result of the above matters for the year ended December 31, 2010 or six months ended June 30, 2011. For greater detail as to legal proceedings, this section should be read in conjunction with NOTE 14 - Contingencies in our Annual Report on Form 10-K for the year ended December 31, 2010.

ITEM 1A. Risk Factors.

The following cautionary statements identify important factors that could cause our actual results to differ materially from those projected in the forward-looking statements made in this Form 10-Q. Among the key factors that have a direct bearing on our results of operations are:

Risks Associated With Our Business

No assurance of successful product development.

Ampligen® and related products. The development of Ampligen® and our other related products is subject to a number of significant risks. Ampligen® may be found to be ineffective or to have adverse side effects, fail to receive necessary regulatory clearances, be difficult to manufacture on a commercial scale, be uneconomical to market or be precluded from commercialization by proprietary right of third parties. Our investigational products are in various stages of clinical and pre-clinical development and require further clinical studies and appropriate regulatory approval processes before any such products can be marketed. We do not know when, if ever, Ampligen® or our other products will be generally available for commercial sale for any indication. Generally, only a small percentage of potential therapeutic products are eventually approved by the FDA for commercial sale. Please see the next risk factor.

Alferon N Injection®. Although Alferon N Injection® is approved for marketing in the United States for the intra-lesional treatment of refractory or recurring external genital warts in patients 18 years of age or older, to date it has not been approved for other indications. We face many of the risks discussed above, with regard to developing this product for use to treat other ailments.

Our drug and related technologies are investigational and subject to regulatory approval. If we are unable to obtain regulatory approval, our operations will be significantly adversely affected.

All of our drugs and associated technologies, other than Alferon N Injection®, are investigational and must receive prior regulatory approval by appropriate regulatory authorities for commercial distribution and sale and are currently legally available only through clinical trials with specified disorders. At present, Alferon N Injection® is only approved for the intra-lesional treatment of refractory or recurring external genital warts in patients 18 years of age or older. Use of Alferon N Injection® for other indications will require regulatory approval.

Our products, including Ampligen®, are subject to extensive regulation by numerous governmental authorities in the United States (“U.S.”) and other countries, including, but not limited to, the FDA in the U.S., the Health Protection Branch (“HPB”) of Canada, and the Agency for the Evaluation of Medicinal Products (“EMEA”) in Europe. Obtaining regulatory approvals is a rigorous and lengthy process and requires the expenditure of substantial resources. In order to obtain final regulatory approval of a new drug, we must demonstrate to the satisfaction of the regulatory agency that the product is safe and effective for its intended uses and that we are capable of manufacturing the product to the applicable regulatory standards. We require regulatory approval in order to market Ampligen® or any other proposed product and receive product revenues or royalties. We cannot assure you that Ampligen® will ultimately be demonstrated to be safe or efficacious. While Ampligen® is authorized for use in clinical trials in the U.S. and Europe, we cannot assure you that additional clinical trial approvals will be authorized in the United States or in other countries, in a timely fashion or at all, or that we will complete these clinical trials. In addition, although Ampligen® has been authorized by the FDA for treatment use under certain conditions, including provision for cost recovery, there can be no assurance that such authorization will continue in effect.

In July 2008, the FDA accepted for review our NDA for Ampligen® to treat CFS, originally submitted in October 2007. On November 25, 2009, we received a Complete Response Letter (“CRL”) from the FDA which described specific additional recommendations related to the Ampligen® NDA. In accordance with its 2008 Complete Response procedure, the FDA reviewers determined that they could not approve the application in its present form and provided specific recommendations to address the outstanding issues. In December 2010, the FDA granted us a one year extension to file a response to the CRL. The Company is diligently working to address the diagnostic challenges related to CFS. Please see “Overview; General; Ampligen®” and “Progress in Search of CFS Test” of Part 1, Item 2 above for more detailed information on the current status of the NDA and CRL.

The production of Alferon N Injection® from the Work-In-Progress Inventory continued into January 2011 with its conversion into Active Pharmaceutical Ingredient (“API”) and is near completion for the related Final Lot Release Test. To formulate, fill and finish Alferon N Injection® Drug Product, we require a FDA approved third party Contract Manufacturing Organization (“CMO”). In June 2011, our designated CMO reported to us that they had received an FDA 483 form that identified production issues that needed to be addressed prior to resumption of production. As a result, we have deemed it necessary to seek an alternative CMO to undertake the Formulation Fill and Finish process. When a new CMO is selected, it will be necessary to conduct tests to qualify the new CMO. The supporting data must then be submitted to the FDA, and the CMO approved by the FDA, prior to our being able to commercially sell Alferon N Injection®. Please see “Overview; General; Alferon N Injection®” of Part 1, Item 2 above for more detailed information.

Alferon® LDO is undergoing pre-clinical testing for possible use as prophylaxis against influenza. While the studies to date have been encouraging, preliminary testing in the laboratory and in animal models is not necessarily predictive of successful results in clinical testing or human treatment. No assurance can be given that similar results will be observed in clinical trials. Use of Alferon® as a possible treatment of any influenza requires prior regulatory approval. In October 2009, we submitted a protocol to the FDA proposing to conduct a Phase II study for the prophylaxis and treatment of seasonal and pandemic influenza of more than 200 subjects. As discussed above in “Overview; General; Alferon® Low Dose Oral (LDO)”, in November 2009, the FDA placed the proposed study on clinical hold. On December 22, 2010, the FDA informed us that it had completed its review of our complete response to the Clinical Hold and lifted the Clinical Hold, allowing our Phase II Study to proceed. As an element of our early stage preparation for the Phase II Study, we are conducting a confirmatory study for systemic effects in peripheral blood leukocytes following the treatment with Alferon® LDO. The outcome of this study will allow us to better evaluate the potential effectiveness of this product and determine the cost/benefit of proceeding with this study of seasonal and pandemic influenza. Please see “Overview; General; Alferon® LDO” of Part 1, Item 2 above for more detailed information. We are unable to provide any assurances that Phase II Alferon® LDO study for the prophylaxis and treatment of seasonal and pandemic influenza will be undertaken.

If we are unable to generate the additional data or successfully complete inspections required by the FDA, determine that a clinical study is not cost/justified to undertake or if, for that or any other reason, Ampligen®, Alferon® or one of our other products or production process does not receive necessary regulatory approval in the U.S. or elsewhere, our operations most likely will be materially adversely affected.

We may continue to incur substantial losses and our future profitability is uncertain.

We began operations in 1966 and last reported net profit from 1985 through 1987. Since 1987, we have incurred substantial operating losses, as we pursued our clinical trial effort to get our experimental drug, Ampligen®, approved. As of June 30, 2011, our accumulated deficit was approximately $(220,885,000). We have not yet generated significant revenues from our products and may incur substantial and increased losses in the future. We cannot assure that we will ever achieve significant revenues from product sales or become profitable. We require, and will continue to require, the commitment of substantial resources to develop our products. We cannot assure that our product development efforts will be successfully completed or that required regulatory approvals will be obtained or that any products will be manufactured and marketed successfully, or be profitable.

We may require additional financing which may not be available; the limited number of shares of common stock available for financing or other purposes may hinder our ability to raise additional funding or utilize equity securities for other corporate purposes.

The development of our products will require the commitment of substantial resources to conduct the time consuming research, preclinical development, and clinical trials that are necessary to bring pharmaceutical products to market. As of June 30, 2011, we had approximately $39,754,000 in Cash, Cash Equivalents and Marketable Securities. Given the harsh economic conditions, we continue to review every aspect of our operations for cost and spending reductions to assure our long-term financial stability while maintaining the resources necessary to achieve our primary objectives of obtaining NDA approval of Ampligen®, and securing a strategic partner.

-36-

If we are unable to commercialize and sell Ampligen® or Alferon® LDO and/or recommence and increase sales of Alferon N Injection® or our other products, we eventually may need to secure other sources of funding through additional equity or debt financing or other sources in order to satisfy our working capital needs and/or complete the necessary clinical trials and the regulatory approval processes on which the commercialization of our products depends.

Our ability to raise additional funds from the sale of equity securities may be limited. In this regard, we only have approximately 31,800,000 shares authorized but unissued and unreserved. We did not gather the requisite votes at our annual stockholders’ meeting held in June 2009 to amend our Certificate of Incorporation to increase the number of authorized shares of Common Stock from 200,000,000 to 350,000,000. Since we have not been able to obtain approval to increase the number of authorized shares of Common Stock, the amount of proceeds we may receive from the sale of our remaining Common Stock may be limited.

There can be no assurances that we will raise adequate funds which may have a material adverse effect on our ability to develop our products or continue our operations.

Our Alferon N Injection® Commercial Sales were halted due to lack of finished goods inventory.

Commercial sales of Alferon N Injection® were halted in March 2008 when our finished goods inventory expired. The production of Alferon N Injection® from the Work-In-Progress Inventory continued into January 2011 with its conversion into Active Pharmaceutical Ingredient (“API”) and is near completion of the Final Lot Release Test. To formulate, fill and finish Alferon N Injection® Drug Product, we require an FDA approved third party CMO. In June 2011, our designated CMO reported to us that they had received an FDA 483 form that identified production issues that needed to be addressed prior to resumption of production. As a result, we have deemed it necessary to seek an alternative CMO to undertake the Formulation Fill and Finish process. When a new CMO is selected, it will be necessary to conduct tests to qualify the new CMO. The supporting data must then be submitted to the FDA, and the CMO approved by the FDA, prior to our being able to commercially sell Alferon N Injection®. Due to this delay in the final external stage of the production process, we estimate that commercial sales of Alferon N Injection® will not resume until early 2012.

We have undertaken at our New Brunswick facility a major capital improvement program that continues in 2011 to enhance our manufacturing capability to produce bulk quantities of API, a purified drug concentrate used in the formulation of Alferon N Injection® at the CMO,. As with all major changes to a FDA approved pharmaceutical manufacturing process, certain of the plant and equipment improvements being implemented for production of Alferon N Injection® may require FDA review prior to commercial sale of the resulting new product, and each production lot of Alferon N Injection® using this new process is subject to FDA review and approval prior to releasing the lots to be sold.

In light of these contingencies, there can be no assurances that the approved Alferon N Injection® product will be returned to production on a timely basis, if at all, or that if and when it is again made commercially available, it will return to prior sales levels.

-37-

Although we believe that preliminary in vitro testing indicates that Ampligen® enhances the effectiveness of different drug combinations on avian influenza, preliminary testing in the laboratory is not necessarily predictive of successful results in clinical testing or human treatment and our former contract partner in Japan has raised questions about certain safety data relating to this use.

Ampligen® has been tested as a vaccine adjuvant for H5N1, a pathogenic avian influenza virus in the laboratories of Dr.Hasegawa at the National Institute of Infectious Diseases in Japan, where the preclinical data has shown activity in preventing lethal challenge with the original N5N1 viral strain used for vaccination as well as the other related, but not identical, isolates of H5N1 virus (i.e., cross-reactivity). We had an agreement regarding Ampligen® with Biken pursuant to which we supplied Biken with proprietary information related to Ampligen® and Biken purchased Ampligen® from us for use solely in connection with evaluating Ampligen® as a candidate for adjuvant incorporated into potential influenza virus vaccines in the form of intranasal mucosal administration. Biken concluded that it was possible that Ampligen® would not satisfy the requirements for safety as an adjuvant for influenza vaccines in Japan. Biken’s primary concern was related to a single intravenous high dose study in rats that resulted in an apparent toxicity when doses of Ampligen® were combined with a whole viron influenza vaccine and Carboxyl Vinyl Polymer (“CVP”) or CVP alone. Additionally in both cases of Ampligen® being combined with other product(s), the dosage utilized was several hundred times higher than the intended dosage for humans by body weight and delivered intravenously, rather than the prescribed mucosal (nasal) method. While we have disputed Biken’s findings, the relationship has effectively ended with no further resolution to the dispute expected. See “Overview; General; Other Viral Diseases” in Part I, Item 2 above.

No assurance can be given that positive results will be observed in clinical trials. Use of Ampligen® or Alferon® in the treatment of influenza requires prior regulatory approval. Only the FDA or other corresponding regulatory agencies world-wide can determine whether a drug is safe, effective and appropriate for treating a specific application. As discussed above, obtaining regulatory approvals is a rigorous and lengthy process (see “Our drugs and related technologies are investigational and subject to regulatory approval. If we are unable to obtain regulatory approval, our operations will be significantly adversely affected” above). If we are unable to obtain the necessary regulatory approval in the U.S. or elsewhere, unable to generate the data of successfully completion of clinical studies, determine that a clinical study is not cost/justified to undertake or if, for that or any other reason, our operations most likely will be materially adversely affected.

We may not be profitable unless we can protect our patents and/or receive approval for additional pending patents.

We need to preserve and acquire enforceable patents covering the use of Ampligen® for a particular disease in order to obtain exclusive rights for the commercial sale of Ampligen® for such disease. We obtained all rights to Alferon N Injection®, and we plan to preserve and acquire enforceable patents covering its use for existing and potentially new diseases. Our success depends, in large part, on our ability to preserve and obtain patent protection for our products and to obtain and preserve our trade secrets and expertise. Certain of our know-how and technology is not patentable, particularly the procedures for the manufacture of our experimental drug, Ampligen®. We also have been issued patents on the use of Ampligen® in combination with certain other drugs for the treatment of chronic Hepatitis B virus, chronic Hepatitis C virus, and a patent which affords protection on the use of Ampligen® in patients with Chronic Fatigue Syndrome. We have not yet been issued any patents in the United States for the use of AmpligenÒ as a sole treatment for any of the cancers which we have sought to target. With regard to Alferon N Injection®, we have acquired from ISI its patents for natural alpha interferon produced from human peripheral blood leukocytes and its production process and we have filed a patent application for the use of Alferon® LDO in treating viral diseases including avian influenza. We cannot assure that our competitors will not seek and obtain patents regarding the use of similar products in combination with various other agents, for a particular target indication prior to our doing so. If we cannot protect our patents covering the use of our products for a particular disease, or obtain additional patents, we may not be able to successfully market our products.

The patent position of biotechnology and pharmaceutical firms is highly uncertain and involves complex legal and factual questions.

To date, no consistent policy has emerged regarding the breadth of protection afforded by pharmaceutical and biotechnology patents. There can be no assurance that new patent applications relating to our products, process or technology will result in patents being issued or that, if issued, such patents will afford meaningful protection against competitors with similar technology. It is generally anticipated that there may be significant litigation in the industry regarding patent and intellectual property rights. Such litigation could require substantial resources from us and we may not have the financial resources necessary to enforce the patent rights that we hold. No assurance can be made that our patents will provide competitive advantages for our products, process and technology or will not be successfully challenged by competitors. No assurance can be given that patents do not exist or could not be filed which would have a materially adverse effect on our ability to develop or market our products or to obtain or maintain any competitive position that we may achieve with respect to our products. Our patents also may not prevent others from developing competitive products or process using related technology.

There can be no assurance that we will be able to obtain necessary licenses if we cannot enforce patent rights we may hold. In addition, the failure of third parties from whom we currently license certain proprietary information or from whom we may be required to obtain such licenses in the future, to adequately enforce their rights to such proprietary information, could adversely affect the value of such licenses to us.

If we cannot enforce the patent rights we currently hold we may be required to obtain licenses from others to develop, manufacture or market our products. There can be no assurance that we would be able to obtain any such licenses on commercially reasonable terms, if at all. We currently license certain proprietary information from third parties, some of which may have been developed with government grants under circumstances where the government maintained certain rights with respect to the proprietary information developed. No assurances can be given that such third parties will adequately enforce any rights they may have or that the rights, if any, retained by the government will not adversely affect the value of our license.

There is no guarantee that our trade secrets will not be disclosed or known by our competitors.

To protect our rights, we require all employees and certain consultants to enter into confidentiality agreements with us. There can be no assurance that these agreements will not be breached, that we would have adequate and enforceable remedies for any breach, or that any trade secrets of ours will not otherwise become known or be independently developed by competitors.

We have limited marketing and sales capability. If we are unable to obtain additional distributors and our current and future distributors do not market our products successfully, we may not generate significant revenues or become profitable.

We have limited marketing and sales capability. We are dependent upon existing and, possibly future, marketing agreements and third party distribution agreements for our products in order to generate significant revenues and become profitable. As a result, any revenues received by us will be dependent in large part on the efforts of third parties, and there is no assurance that these efforts will be successful.

Our commercialization strategy for Ampligen® may include licensing/co-marketing agreements utilizing the resources and capacities of one or more strategic partners. We continue to seek world-wide marketing partner(s), with the goal of having a relationship in place before approval is obtained. In parallel to partnering discussions, appropriate premarketing activities will be undertaken. We intend to control manufacturing of Ampligen® on a world-wide basis.

-39-

Our commercialization strategy for Alferon N Injection® may include the utilization of newly employed internal functions and/or licensing/co-marketing agreements that would utilize the resources and capacities of one or more strategic partners. Our agreement with a third party to market and sell Alferon N Injection® is outdated and we are seeking to either promptly renew our prior agreement with the same third-party vendor or find another vendor that can provide the services desired.

We cannot assure that our U.S. or foreign marketing strategy will be successful or that we will be able to establish future marketing or third party distribution agreements on terms acceptable to us, or that the cost of establishing these arrangements will not exceed any product revenues. Our inability to establish viable marketing and sales capabilities would most likely have a materially adverse effect on us. There can be no assurances that the approved Alferon N Injection® product will be returned to prior sales levels.

There are no long-term agreements with suppliers of required materials and services. If we are unable to obtain the required raw materials and/or services, we may not be able to manufacture Alferon N Injection® and/or Ampligen®.

A number of essential materials are used in the production of Alferon N Injection®. We do not have, but continue to work towards having long-term agreements for the supply of such materials. There can be no assurance we can enter into long-term supply agreements covering essential materials on commercially reasonable terms, if at all.

There are a limited number of organizations in the United States available to provide the final steps in the manufacturing Alferon N Injection®. At present, we do not have and are seeking an agreement with a third party Contract Manufacturing Organization to complete the Formulation Fill and Finish process related to the final steps in the manufacturing of Alferon N Injection® as to allow us to qualify and obtain FDA approval for the CMO and to potentially resume commercial sales by early 2012. If we were unable to obtain this necessary service, it could adversely impact our ability to timely relaunch Alferon N Injection® for commercial sales. In light of this contingency, there can be no assurances that the approved Alferon N Injection® product will be returned to commercial sales on a timely basis, if at all, or that if and when it is again made commercially available, it will return to prior sales levels.

We outsource certain components of our research and development, manufacturing, marketing and distribution while maintaining control over the entire process through our Quality Assurance Group and our Clinical Monitoring Group. We had a Supply Agreement through March 1, 2011 with Hollister-Stier Laboratories LLC of Spokane, Washington (“Hollister-Stier”), pursuant to which Hollister-Stier would formulate and package Ampligen® from the key raw materials that we would supply to Hollister-Stier. We are actively negotiating with Hollister-Stier to renew the supply agreement. If we are unable to renew or extend the Hollister-Stier agreement, we will need to seek out an alternative vendor to formulate and package Ampligen® so that final manufacturing steps can be undertaken.

There are a limited number of manufacturers in the United States available to provide the polymers for use in manufacturing Ampligen®. At present, we do not have any agreements with third parties for the supply of any of these polymers. We have established relevant manufacturing operations within our New Brunswick, New Jersey facility for the production of Ampligen® polymers from raw materials in order to obtain polymers on a more consistent manufacturing basis in the quantities necessary for clinical testing.

-40-

If we are unable to obtain or manufacture the required raw materials, as well as procure services needed in the final steps in the manufacturing process, we may be unable to manufacture Alferon N Injection® and/or Ampligen®. The costs and availability of products and materials we need for the production of Ampligen® and the commercial production of Alferon N Injection® and other products which we may commercially produce are subject to fluctuation depending on a variety of factors beyond our control, including competitive factors, changes in technology, and FDA and other governmental regulations and there can be no assurance that we will be able to obtain such products and materials on terms acceptable to us or at all.

There is no assurance that successful manufacture of a drug on a limited scale basis for investigational use will lead to a successful transition to commercial, large-scale production.

Changes in methods of manufacturing, including commercial scale-up, may affect the chemical structure of Ampligen® and other RNA drugs, as well as their safety and efficacy. The transition from limited production of pre-clinical and clinical research quantities to production of commercial quantities of our products will involve distinct management and technical challenges and will require additional management and technical personnel and capital to the extent such manufacturing is not handled by third parties. There can be no assurance that our manufacturing will be successful or that any given product will be determined to be safe and effective, or capable of being manufactured under applicable quality standards, economically, and in commercial quantities, or successfully marketed.

We have limited manufacturing experience.

Ampligen® has been produced to date in limited quantities for use in our clinical trials, and we are dependent upon a qualified third party supplier for the manufacturing and packaging process. The failure to continue these arrangements or to achieve other such arrangements on satisfactory terms could have a material adverse effect on us. Also, to be successful, our products must be manufactured in commercial quantities in compliance with regulatory requirements and at acceptable costs. To the extent we are involved in the production process, our current facilities may not be adequate for the production of our proposed products for large-scale commercialization. We intend to utilize third party facilities if and when the need arises or, if we are unable to do so, to build or acquire commercial-scale manufacturing facilities. We will need to comply with regulatory requirements for such facilities, including those of the FDA pertaining to cGMP requirements. There can be no assurance that such facilities can be used, built, or acquired on commercially acceptable terms, or that such facilities, if used, built, or acquired, will be adequate for our long-term needs.

We may not be profitable unless we can produce Ampligen®, Alferon N Injection® or other products in commercial quantities at costs acceptable to us.

We have never produced Ampligen® or any other products in large commercial quantities. We must manufacture our products in compliance with regulatory requirements in large commercial quantities and at acceptable costs in order for us to be profitable. We intend to utilize third party manufacturers and/or facilities if and when the need arises or, if we are unable to do so, to build or acquire commercial-scale manufacturing facilities. If we cannot manufacture commercial quantities of Ampligen® or enter into third party agreements for its manufacture at costs acceptable to us, our operations will be significantly affected. Also, each production lot of Alferon N Injection® is subject to FDA review and approval prior to releasing the lots to be sold. This review and approval process could take considerable time, which would delay our having product in inventory to sell. There can be no assurances that the approved Alferon N Injection® product will be returned to commercial sales on a timely basis, if at all, or that if and when it is again made commercially available, it will return to prior sales levels.

-41-

Rapid technological change may render our products obsolete or non-competitive.

The pharmaceutical and biotechnology industries are subject to rapid and substantial technological change. Technological competition from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase. Most of these entities have significantly greater research and development capabilities than us, as well as substantial marketing, financial and managerial resources, and represent significant competition for us. There can be no assurance that developments by others will not render our products or technologies obsolete or noncompetitive or that we will be able to keep pace with technological developments.

Our products may be subject to substantial competition.

Ampligen®. Competitors may be developing technologies that are, or in the future may be, the basis for competitive products. Some of these potential products may have an entirely different approach or means of accomplishing similar therapeutic effects to products being developed by us. These competing products may be more effective and less costly than our products. In addition, conventional drug therapy, surgery and other more familiar treatments may offer competition to our products. Furthermore, many of our competitors have significantly greater experience than us in preclinical testing and human clinical trials of pharmaceutical products and in obtaining FDA, HPB and other regulatory approvals of products. Accordingly, our competitors may succeed in obtaining FDA, HPB or other regulatory product approvals more rapidly than us. There are no drugs approved for commercial sale with respect to treating ME/CFS in the United States. The dominant competitors with drugs to treat disease indications in which we plan to address include Gilead Sciences, Pfizer, Bristol-Myers Squibb, Abbott Laboratories, GlaxoSmithKline and Merck. These potential competitors are among the largest pharmaceutical companies in the world, are well known to the public and the medical community, and have substantially greater financial resources, product development, and manufacturing and marketing capabilities than we have. Although we believe our principal advantage is the unique mechanism of action of Ampligen® on the immune system, we cannot assure that we will be able to compete.

Alferon N Injection®. Our competitors are among the largest pharmaceutical companies in the world, are well known to the public and the medical community, and have substantially greater financial resources, product development, and manufacturing and marketing capabilities than we have. Alferon N Injection® currently competes with Schering’s injectable recombinant alpha interferon product (INTRON® A) for the treatment of genital warts. 3M Pharmaceuticals also offer competition from its immune-response modifier, Aldara®, a self-administered topical cream, for the treatment of external genital and perianal warts. In addition, Medigene AG has FDA approval for a self-administered ointment, Veregen®, which is indicated for the topical treatment of external genital and perianal warts. Alferon N Injection® also competes with surgical, chemical, and other methods of treating genital warts. We cannot assess the impact products developed by our competitors, or advances in other methods of the treatment of genital warts, will have on the commercial viability of Alferon N Injection®. If and when we obtain additional approvals of uses of this product, we expect to compete primarily on the basis of product performance. Our competitors have developed or may develop products (containing either alpha or beta interferon or other therapeutic compounds) or other treatment modalities for those uses. There can be no assurance that, if we are able to obtain regulatory approval of Alferon N Injection® for the treatment of new indications, we will be able to achieve any significant penetration into those markets. In addition, because certain competitive products are not dependent on a source of human blood cells, such products may be able to be produced in greater volume and at a lower cost than Alferon N Injection®. Currently, our wholesale price on a per unit basis of Alferon N Injection® is higher than that of the competitive recombinant alpha and beta interferon products.

General. Other companies may succeed in developing products earlier than we do, obtaining approvals for such products from the FDA more rapidly than we do, or developing products that are more effective than those we may develop. While we will attempt to expand our technological capabilities in order to remain competitive, there can be no assurance that research and development by others or other medical advances will not render our technology or products obsolete or non-competitive or result in treatments or cures superior to any therapy we develop.

-42-

Possible side effects from the use of Ampligen® or Alferon N Injection® could adversely affect potential revenues and physician/patient acceptability of our product.

Ampligen®. We believe that Ampligen® has been generally well tolerated with a low incidence of clinical toxicity, particularly given the severely debilitating or life threatening diseases that have been treated. A mild flushing reaction has been observed in approximately 15-20% of patients treated in our various studies. This reaction is occasionally accompanied by a rapid heart beat, a tightness of the chest, urticaria (swelling of the skin), anxiety, shortness of breath, subjective reports of “feeling hot”, sweating and nausea. The reaction is usually infusion-rate related and can generally be controlled by reducing the rate of infusion. Other adverse side effects include liver enzyme level elevations, diarrhea, itching, asthma, low blood pressure, photophobia, rash, transient visual disturbances, slow or irregular heart rate, decreases in platelets and white blood cell counts, anemia, dizziness, confusion, elevation of kidney function tests, occasional temporary hair loss and various flu-like symptoms, including fever, chills, fatigue, muscular aches, joint pains, headaches, nausea and vomiting. These flu-like side effects typically subside within several months. One or more of the potential side effects might deter usage of Ampligen® in certain clinical situations and therefore, could adversely affect potential revenues and physician/patient acceptability of our product. Biken concluded that it was possible that Ampligen® would not satisfy the requirements for safety as an adjuvant for influenza vaccines in Japan. Biken’s primary concern was related to a single intravenous high dose study in rats that resulted in an apparent toxicity when doses of Ampligen® were combined with a whole viron influenza vaccine and Carboxyl Vinyl Polymer (“CVP”) or CVP alone. Additionally in both cases of Ampligen® being combined with other product(s), the dosage utilized was several hundred times higher than the intended dosage for humans by body weight and delivered intravenously, rather than the prescribed mucosal (nasal) method. We dispute Biken’s findings. See “Overview; General; Other Viral Diseases” in Part I above.

Alferon N Injection®. At present, Alferon N Injection® is only approved for the intra-lesional (within the lesion) treatment of refractory or recurring external genital warts in adults. In clinical trials conducted for the treatment of genital warts with Alferon N Injection®, patients did not experience serious side effects; however, there can be no assurance that unexpected or unacceptable side effects will not be found in the future for this use or other potential uses of Alferon N Injection® which could threaten or limit such product’s usefulness.

We may be subject to product liability claims from the use of Ampligen®, Alferon N Injection®, or other of our products which could negatively affect our future operations. We have limited product liability insurance.

We face an inherent business risk of exposure to product liability claims in the event that the use of Ampligen®, Alferon N Injection® or other of our products results in adverse effects. This liability might result from claims made directly by patients, hospitals, clinics or other consumers, or by pharmaceutical companies or others manufacturing these products on our behalf. Our future operations may be negatively affected from the litigation costs, settlement expenses and lost product sales inherent to these claims. While we will continue to attempt to take appropriate precautions, we cannot assure that we will avoid significant product liability exposure.

We maintain Products Liability and Clinical Trial insurance world-wide coverage for Ampligen® and Alferon®. However even with retaining Products Liability and Clinical Trial insurance coverage for Ampligen®, Alferon N Injection® and Alferon® LDO, a claim against the products could have a materially adverse effect on our business and financial condition.

-43-

We face an inherent business risk of exposure to product liability claims in the event that the use of Ampligen®, Alferon N Injection® or other of our products results in adverse effects. This liability might result from domestic or international claims made directly by patients, hospitals, clinics or other consumers, or by pharmaceutical companies, insurance companies or others manufacturing these products on our behalf. Our future operations may be negatively affected from the litigation costs, settlement expenses and lost product sales inherent to these claims. While we will continue to attempt to take appropriate precautions, we cannot assure that we will avoid significant product liability exposure.

The loss of services of key personnel including Dr. William A. Carter could hurt our chances for success.

Our success is dependent on the continued efforts of our staff, especially certain doctors and researchers along with the continued efforts of Dr. William A. Carter because of his position as a pioneer in the field of nucleic acid drugs, his being the co-inventor of Ampligen®, and his knowledge of our overall activities, including patents and clinical trials. The loss of the services of Dr. Carter or other personnel key to our operations, could have a material adverse effect on our operations and chances for success. As a cash conservation measure, we have elected to discontinue the Key Man life insurance on the life of Dr. Carter. An employment agreement continues to exist with Dr. Carter that, as amended, runs until December 31, 2015. However, Dr. Carter has the right to terminate his employment upon not less than 30 days prior written notice. The loss of Dr. Carter or other key personnel or the failure to recruit additional personnel as needed could have a materially adverse effect on our ability to achieve our objectives.

Uncertainty of health care reimbursement for our products.

Our ability to successfully commercialize our products will depend, in part, on the extent to which reimbursement for the cost of such products and related treatment will be available from government health administration authorities, private health coverage insurers and other organizations. Significant uncertainty exists as to the reimbursement status of newly approved health care products, and from time to time legislation is proposed, which, if adopted, could further restrict the prices charged by and/or amounts reimbursable to manufacturers of pharmaceutical products. We cannot predict what, if any, legislation will ultimately be adopted or the impact of such legislation on us. There can be no assurance that third party insurance companies will allow us to charge and receive payments for products sufficient to realize an appropriate return on our investment in product development.

There are risks of liabilities associated with handling and disposing of hazardous materials.

Our business involves the controlled use of hazardous materials, carcinogenic chemicals, flammable solvents and various radioactive compounds. Although we believe that our safety procedures for handling and disposing of such materials comply in all material respects with the standards prescribed by applicable regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident or the failure to comply with applicable regulations, we could be held liable for any damages that result, and any such liability could be significant. We do not maintain insurance coverage against such liabilities.

Risks Associated With an Investment in Our Common Stock

The market price of our stock may be adversely affected by market volatility.

The market price of our common stock has been and is likely to be volatile. This is especially true given the current significant instability in the financial markets. In addition to general economic, political and market conditions, the price and trading volume of our stock could fluctuate widely in response to many factors, including:

-44-

announcements of the results of clinical trials by us or our competitors;

announcement of legal actions against us and/or settlements or verdicts adverse to us;

adverse reactions to products;

governmental approvals, delays in expected governmental approvals or withdrawals of any prior governmental approvals or public or regulatory agency comments regarding the safety or effectiveness of our products, or the adequacy of the procedures, facilities or controls employed in the manufacture of our products;

changes in U.S. or foreign regulatory policy during the period of product development;

developments in patent or other proprietary rights, including any third party challenges of our intellectual property rights;

announcements of technological innovations by us or our competitors;

announcements of new products or new contracts by us or our competitors;

actual or anticipated variations in our operating results due to the level of development expenses and other factors;

changes in financial estimates by securities analysts and whether our earnings meet or exceed the estimates;

conditions and trends in the pharmaceutical and other industries;

new accounting standards;

overall investment market fluctuation;

restatement of prior financial results;

notice of NYSE Amex non-compliance with requirements; and

occurrence of any of the risks described in these "Risk Factors".

Our common stock is listed for quotation on the NYSE Amex. For the six months ended June 30, 2011, the closing price of our common stock has ranged from $0.37 to $0.55 per share. We expect the price of our common stock to remain volatile. The average daily trading volume of our common stock varies significantly.

Our stock price may be adversely affected if a significant amount of shares are sold in the public market.

In May 2009 we issued an aggregate of 25,543,339 shares and warrants to purchase an additional 14,708,687 shares under a universal shelf registration statement. 4,895,000 of these warrants have been exercised as of June 30, 2011. Depending upon market conditions, we anticipate selling 9,813,687 shares pursuant to the conversion of remaining warrants.

Additionally, we registered with the SEC on September 29, 2009, 1,038,527 shares issuable upon exercise of certain other warrants. To the extent the exercise price of our outstanding warrants is less than the market price of the common stock, the holders of the warrants are likely to exercise them and sell the underlying shares of common stock and to the extent that the exercise price of certain of these warrants are adjusted pursuant to anti-dilution protection, the warrants could be exercisable or convertible for even more shares of common stock. We also may issue shares to be used to meet our capital requirements or use shares to compensate employees, consultants and/or directors. In this regard we have registered $150,000,000 of securities for public sale pursuant to a universal shelf registration. We have allocated 32,000,000 shares under this registration statement to an At-The-Market equity offering and, as of June 30, 2011, we have sold a total of 520,000 shares pursuant to this offering.

-45-

We are unable to estimate the amount, timing or nature of future sales of outstanding common stock or instruments convertible into or exercisable for our common stock. Sales of substantial amounts of our common stock in the public market, including additional sale of securities pursuant to the universal shelf registration statement or upon exercise of outstanding options, could cause the market price for our common stock to decrease. Furthermore, a decline in the price of our common stock would likely impede our ability to raise capital through the issuance of additional shares of common stock or other equity securities.

Provisions of our Certificate of Incorporation and Delaware law could defer a change of our management which could discourage or delay offers to acquire us.

Provisions of our Certificate of Incorporation and Delaware law may make it more difficult for someone to acquire control of us or for our stockholders to remove existing management, and might discourage a third party from offering to acquire us, even if a change in control or in Management would be beneficial to our stockholders. For example, our Certificate of Incorporation allows us to issue shares of preferred stock without any vote or further action by our stockholders. Our Board of Directors has the authority to fix and determine the relative rights and preferences of preferred stock. Our Board of Directors also has the authority to issue preferred stock without further stockholder approval. As a result, our Board of Directors could authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, prior to the redemption of our common stock. In this regard, in November 2002, we adopted a Stockholder Rights Plan (“Rights Plan”) and, under the Rights Plan, our Board of Directors declared a dividend distribution of one Right for each outstanding share of Common Stock to stockholders of record at the close of business on November 29, 2002. Each Right initially entitles holders to buy one-hundredth unit of preferred stock for $30.00. The Rights generally are not transferable apart from the common stock and will not be exercisable unless and until a person or group acquires or commences a tender or exchange offer to acquire, beneficial ownership of 15% or more of our common stock. However, for Dr. Carter, our Chief Executive Officer, who already beneficially owns 5.65% of our common stock, the Rights Plan’s threshold will be 20%, instead of 15%. The Rights Plan will expire on November 19, 2012, and may be redeemed prior thereto at $.01 per Right under certain circumstances.

Special Note Regarding Forward Looking Statements

Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us, you should not place undue reliance on any such forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Our research in clinical efforts may continue for the next several years and we may continue to incur losses due to clinical costs incurred in the development of Ampligen® for commercial application. Possible losses may fluctuate from quarter to quarter as a result of differences in the timing of significant expenses incurred and receipt of licensing fees and/or cost recovery treatment revenue.
