Our Business

Discovery Laboratories, Inc. is a specialty biotechnology company focused on creating life-saving products for critical care patients with respiratory disease and improving the standard of care in pulmonary medicine.  Our proprietary drug technology produces a synthetic, peptide-containing surfactant (KL4 surfactant) that is structurally similar to pulmonary surfactant, a substance produced naturally in the lung and essential for normal respiratory function and survival.  We are developing our KL4 surfactant in liquid, lyophilized and aerosolized dosage forms.  We are also developing novel drug delivery technologies potentially to enable the efficient delivery of our aerosolized KL4 surfactant, and potentially other aerosolized drugs and inhaled therapies.  We believe that our proprietary technologies make it possible, for the first time, to develop a significant pipeline of products to address a variety of respiratory diseases for which there frequently are few or no approved therapies.

Our Initial Focus – Respiratory Distress Syndrome (RDS)

We are developing our KL4 surfactant and drug delivery technologies initially to improve the management of RDS in premature infants.  RDS is a serious respiratory condition caused by insufficient surfactant production in underdeveloped lungs of premature infants, and the most prevalent respiratory disease in the neonatal intensive care unit (NICU).  RDS can result in long-term respiratory problems, developmental delay and death.  Mortality and morbidity rates associated with RDS have not meaningfully improved over the last decade.  We believe that the RDS market is presently underserved, and that our RDS programs have the potential to greatly improve the management of RDS and, over time, to become a new standard of care for premature infants with RDS.

Premature infants with RDS currently are treated with surfactants that can only be administered by endotracheal intubation supported with mechanical ventilation, both invasive procedures that frequently result in serious respiratory conditions and complications.  To avoid such adverse results, neonatologists generally provide surfactants as initial therapy only to premature infants with severe RDS where the potential benefits of surfactant therapy outweigh the risks associated with endotracheal intubation and mechanical ventilation.  For infants with less severe RDS, neonatologists will first attempt to provide respiratory support using a less invasive means, such as nasal continuous positive airway pressure (nCPAP).  Unfortunately, a significant number of these infants do not respond adequately to nCPAP, an outcome referred to as nCPAP failure, and may require subsequent surfactant administration via intubation and mechanical ventilation.  As it is not possible to ascertain in advance which patients will experience nCPAP failure, neonatologists are faced with a dilemma, because the outcome for those infants who experience nCPAP failure and receive delayed surfactant therapy may not be as favorable as the outcome for those infants who receive surfactant therapy as initial therapy.

In the United States, approximately 360,000 premature births occur each year, of which we estimate that approximately 160,000 premature infants could potentially benefit from early surfactant therapy to address surfactant deficiency or insufficiency.  However, only approximately 45,000 will receive surfactants administered using intubation and mechanical ventilation as the first line of therapy, and more than 70% of surfactant deficient infants (approximately 115,000) will not receive first-line surfactant therapy and instead receive nCPAP alone.  Of those infants that are treated with nCPAP alone, approximately 45,000 will require subsequent endotracheal intubation and surfactant therapy.
- 4 -

We believe that the neonatal medical community increasingly recognizes the potential benefits of (i) a synthetic, peptide-containing surfactant such as SURFAXIN®, and more importantly, (ii) a less-invasive method of delivering surfactant, such as AEROSURF®, to treat premature infants at risk of suffering from respiratory disorders.

SURFAXIN®
Our first KL4 surfactant drug product, SURFAXIN (lucinactant) Intratracheal Suspension for the prevention of RDS in premature infants at high risk for RDS, was approved by the U.S. Food and Drug Administration (FDA) in 2012.  SURFAXIN is the first synthetic, peptide-containing surfactant approved by the FDA and the only alternative to animal-derived surfactants currently used in the U.S.  On October 4, 2013, we announced that the FDA has agreed to updated product specifications for SURFAXIN, and that we have initiated manufacturing of SURFAXIN drug product for commercial sale.  On November 8, 2013, we announced that SURFAXIN is commercially available in the U.S.

AEROSURF®
AEROSURF is an investigational combination drug-device product that combines our KL4 surfactant with our proprietary capillary aerosol generator (CAG).  We are developing AEROSURF to deliver our KL4 surfactant in aerosolized form to premature infants with RDS.  AEROSURF potentially will provide neonatologists with the ability to avoid invasive procedures and deliver our KL4 surfactant in aerosolized form to premature infants supported with nCPAP.  For this reason, we believe that AEROSURF, if approved, may enable the treatment of a significantly greater number of premature infants with RDS who could benefit from surfactant therapy but are currently not treated.

Based on the expected number of infants that do not receive first-line surfactant therapy and the perceived potential pharmacoeconomic benefits that might be derived from delivering surfactants without endotracheal intubation and mechanical ventilation, we anticipate that the market potential for AEROSURF in the U.S. is in the range of $600 million to over $1 billion.  We believe that the opportunity in markets outside the U.S. is potentially comparable to the U.S.  However, there can be no assurance that we will succeed in gaining approval to market AEROSURF in the U.S. market or in markets outside the U.S., nor can there be assurance that our revenues estimates will be achieved.

AEROSURF Development Plan Update
We are developing a lyophilized (freeze-dried) dosage form of our KL4 surfactant that can be stored as a powder and resuspended to liquid form prior to use, with the objective of improving ease of use for healthcare practitioners, as well as potentially prolonging shelf life and eliminating the need for cold-chain storage.  This lyophilized dosage form is intended initially to be used in our AEROSURF development program.  We completed a technology transfer of our lyophilized surfactant manufacturing process to DSM Pharmaceuticals, Inc. (DSM), our contract manufacturer with expertise in lyophilized products.  DSM has manufactured a supply of clinical drug product needed for the initial phase of our phase 2 program and will manufacture the clinical drug supply needed to complete our phase 2 clinical program.  We also have entered into a development agreement with DSM for the further development of this lyophilized KL4 surfactant, potentially for our AEROSURF phase 3 program and, if approved, commercial supply.

With the assistance of Battelle Memorial Institute (Battelle), we completed development of a clinic-ready CAG device and have manufactured a sufficient number of clinic-ready CAGs to support the initial phase of our AEROSURF phase 2 clinical program.  We plan to continue development of our CAG and expect to manufacture additional devices to support completion of our phase 2 and potentially our phase 3 clinical program.  The CAG has been designed to produce aerosolized KL4 surfactant in volumes up to ten times the output produced by currently available aerosol devices.

AEROSURF Proposed Phase 2 Clinical Program
In November 2013, the FDA cleared Investigational New Drug (IND) Application for our initial AEROSURF phase 2 clinical trial and we are proceeding with our phase 2 clinical program.  We anticipate results from the first phase of our AEROSURF phase 2 clinical program in the third quarter of 2014.

The primary goal of the initial phase of the proposed AEROSURF phase 2 program, phase 2a, is to evaluate the safety and tolerability of a single exposure of  aerosolized KL4 surfactant drug product.  This phase is planned as an escalating dose study evaluating three dose levels of aerosolized KL4 surfactant.  The comparator is nCPAP alone.  The study is being conducted in three centers in the U.S. and is expected to be completed by mid-2014.  The design of the second phase of the study, phase 2b, will be informed by the results of phase 2a.  The primary objective of phase 2b will be to determine the optimal dose and expected efficacy margin.  This phase is expected to be conducted in multiple centers and completed by mid-2015.

Beyond RDS

We expect that we will be able to leverage the information, data and know-how that we gain from our development efforts with AEROSURF for RDS to support development of a product pipeline potentially to address serious critical care respiratory conditions of larger children and adults in PICUs and intensive care units (ICUs).  However, we are currently focusing our resources on advancing the development of AEROSURF through phase 2 clinical trials and the commercial introduction of SURFAXIN.  If we are able to achieve these objectives, we believe we will be in a better position to assess the potential of developing products based on our CAG and other drug delivery technologies to address the critical care needs of patients in the PICU and ICU.

Commercial and Medical Affairs Organizations

In the U.S., we have established our own specialty respiratory critical care commercial and medical affairs organizations that include professionals with experience in neonatal/pediatric respiratory critical care, and are focused on neonatal indications, beginning with the commercial introduction of SURFAXIN and the AFECTAIR® device for infants.  With our established relationships and contacts in the neonatal community, we believe that we also will be able to use our commercial and medical affairs organizations in the future to efficiently support the introductions of AEROSURF and potentially a lyophilized dosage form of SURFAXIN, SURFAXIN LS™, if approved.  In addition, with their expertise in respiratory critical care and in launching new products that address neonatal/pediatric conditions, we expect that these teams may potentially support introductions of other synergistic products in the NICU/PICU.

Note: The RDS population estimates and estimates and data included in the discussion above have been derived from the following sources, among others: IMS MIDAS data (MAT Sept 2008); CDC National Vital Statistics, 2005, Births by birth weight (CDC Website); “Annual Summary of Vital Statistics: 2006”, Pediatrics, Martin et al.; Vermont Oxford Network (VON) data, 2006; UNICEF data, 2005 (website); our primary market research (2010).  Our estimate of the number of premature infants that could potentially benefit from early surfactant therapy is derived from data from the foregoing sources, taking into account several factors, including without limitation, gestational age of premature infants, treatment rates for nCPAP, rates of nCPAP failure, and incidence of RDS.

FINANCING WITH THE DEERFIELD ENTITIES

On February 13, 2013, we entered into a lending facility (the “Deerfield Facility”) with the Deerfield Entities by way of a Facility Agreement, dated February 13, 2013 (the “Facility Agreement”) pursuant to which the Deerfield Entities agreed to provide financing to the Company of up to $30 million on a secured basis, subject to the terms and conditions set forth in the Facility Agreement.

Under the terms of the Facility Agreement, the Deerfield Entities agreed to advance funds to the Company in two disbursements.  The first disbursement in the amount of $10 million occurred upon execution of the Facility Agreement (the “Agreement Date”).  The second disbursement, in the amount of $20 million occurred on December 3, 2013, which was on or about the date of the first commercial sale of SURFAXIN® (lucinactant) for the prevention of respiratory distress syndrome (RDS) in premature infants at high risk for RDS.  At the time of each disbursement, the Company paid to the Deerfield Entities a transaction fee equal to one and one-half percent (1.5%) of the amount disbursed under the Facility Agreement.

Amounts drawn under the Facility Agreement accrue interest at a rate of 8.75% per annum, payable quarterly in cash.  The Company has the right to prepay any amounts owed without penalty.  In addition, at the election of the holders of the notes evidencing loans under the Facility Agreement (“Notes”), the principal amounts of the Notes may be reduced to the extent that the holders elect to apply a portion of the principal amount outstanding under the Notes to satisfy the exercise price of the related Warrants (see below) upon exercise of all or a portion of the Warrants.  The principal amounts outstanding under the Facility Agreement are payable in equal installments on the fourth, fifth and sixth anniversaries of the Facility Agreement; provided that the amount payable on the fourth anniversary shall be deferred for one year if either (i) the Company’s “Net Sales” (defined below) for the immediately preceding 12-month period are at least $20 million, or (ii) the Company’s “Equity Value” (defined below) is at least $200 million; and provided further, that the amount payable on the fifth anniversary (together with any amount deferred on the fourth anniversary) shall be deferred until the sixth anniversary if either (x) the Company’s “Net Sales” for the immediately preceding 12 month period are at least $30 million, or (ii) the Company’s “Equity Value” is at least $250 million.  For the purposes of the foregoing deferrals of principal, “Net Sales” means, without duplication, the gross amount invoiced by or on behalf of the Company, any of its Subsidiaries or any direct or indirect assignee or licensee for products, sold globally in bona fide, arm’s length transactions, less customary deductions determined without duplication in accordance with generally accepted accounting principles; and “Equity Value” means, with respect to each measurement date, the product of (x) the number of issued and outstanding shares of common stock of the Company (the “Common Stock”) on such measurement date multiplied by (y) the per share closing price of the Common Stock on such measurement date.

Additionally, any amounts drawn under the Facility Agreement may become immediately due and payable upon (i) an “Event of Default,” as defined in the Facility Agreement, in which case the Deerfield Entities would have the right to require the Company to repay the outstanding principal amount of the loan, plus any accrued and unpaid interest thereon, or (ii) the occurrence of certain events as defined in the Facility Agreement, including the consummation of a change of control transaction or the sale of more than 50% of the Company’s assets (collectively, a “Major Transaction”).

The Facility Agreement also contains various representations and warranties and affirmative and negative covenants customary for financings of this type, including restrictions on the ability of the Company to incur additional indebtedness and grant additional liens on its assets.

Warrants

In connection with the execution of the Facility Agreement, on February 13, 2013, the Company issued to the Deerfield Entities warrants to purchase an aggregate of 2,340,000 shares of the Common Stock at an exercise price of $2.81 per share of Common Stock, representing a 24% premium to the closing price of Common Stock on The NASDAQ Capital Market on the immediately preceding trading day.  On December 3, 2013, in connection with the second disbursement under the Facility Agreement, the Company issued to the Deerfield Entities warrants to purchase an additional 4,660,000 shares of Common Stock at an exercise price of $2.81 per share of Common Stock (together with the warrants in the preceding sentence, the “Warrants”), representing a 18% premium to the closing price of Common Stock on The NASDAQ Capital Market on the immediately preceding trading day. The number of shares of Common Stock into which a Warrant is exercisable and the exercise price of any Warrant will be adjusted to reflect any stock splits, recapitalizations or similar adjustments in the number of outstanding shares of Common Stock.

- 7 -

Each Warrant issued under the Facility Agreement expires on the sixth anniversary of the Facility Agreement and contains certain limitations that generally prevent the holder from acquiring shares upon exercise of a Warrant that would result in the number of shares beneficially owned by it to exceed 9.985% of the total number of shares of Common Stock then issued and outstanding.  In addition, in no event shall the aggregate number of shares issued by the Company pursuant to the Warrants or the Facility Agreement exceed 8,500,000 shares of Common Stock (which amount shall be adjusted from time to time in connection with a recapitalization or reclassification).

The holder of a Warrant may exercise the Warrants either for cash or on a cashless basis.  In connection with a Major Transaction, as defined in the Warrants, to the extent of consideration payable to stockholders in cash in connection with such Major Transaction, the holder may have the option to redeem the Warrant or that portion of the Warrant for cash in an amount equal to the Black-Scholes value (as defined in the Warrant) of the Warrant or that portion of the Warrant redeemed.  In addition, in connection with a Major Transaction, to the extent of any consideration payable to stockholders in securities, or in the event of an Event of Default, the holder may have the option to exercise the Warrant and receive therefor that number of shares of Common Stock that equals the Black Scholes value of the Warrant or that portion of the Warrant exercised.  Prior to the holder exercising the Warrant for shares in such transactions, the Company may elect to terminate the Warrant or that portion of the Warrant and pay the holder cash in an amount equal to the Black Scholes value of the Warrant.

Registration Rights Agreement

In connection with the Financing, the Company entered into a Registration Rights Agreement with the Deerfield Entities (the “Registration Rights Agreement”) obligating the Company to register for resale the shares of Common Stock issuable upon the exercise of the Warrants or shares issued in connection with an event of default or repayment of the facility pursuant to the terms of the Facility Agreement on a registration statement on Form S-3 to be filed with the Securities and Exchange Commission within 60 days after the applicable Warrants are issued.

Security Agreement

The Company has also entered into a Security Agreement with the Deerfield Entities (the “Security Agreement”), pursuant to which, as security for the Company’s repayment of its obligations under the Facility Agreement, the Company granted to the Deerfield Entities a security interest in substantially all of its assets.

The foregoing summary of the Deerfield Facility does not purport to be complete and is qualified by reference to the Facility Agreement, the Registration Rights Agreement, the Form of Warrant and the Security Agreement, copies of which have been filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part.

RISK FACTORS
 
An investment in our common stock involves significant risks.  You should carefully consider the risks described below or in any applicable prospectus supplement and other information, including our financial statements and related notes previously included in our periodic reports filed with the SEC, and in the documents incorporated therein by reference before deciding to invest in our securities, including without limitation, our Annual Report on Form 10-K for the year ended December 31, 2012 and our Quarterly and Current Reports filed thereafter, each of which is incorporated herein by reference.  The risks described below are not the only ones that we face.  Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations.  The following risks, among others, could cause our actual results, performance, achievements or industry results to differ materially from those expressed in our forward-looking statements contained herein and presented elsewhere by management from time to time. If any of the following risks actually occurs, our business prospects, financial condition or results of operations could be materially harmed.  In such case, the market price of our securities would likely and you could lose all or part of your investment.
 
Risks Related to this Offering and Our Common Stock

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

The market price of our common stock, like that of many other development stage pharmaceutical or biotechnology companies, has been and is likely to continue to be volatile.  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:

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

            patient adverse reactions to drug products;

            governmental approvals, delays in expected governmental approvals or withdrawals of any prior governmental approvals or public or regulatory agency concerns regarding the safety or effectiveness of our products;

            changes in the United States or foreign regulatory policy during the period of product development;

            changes in the United States or foreign political environment and the passage of laws, including tax, environmental or other laws, affecting the product development business;

            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;

            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; and

            the occurrence of any of the risks described in these “Risk Factors” or in our Annual Report on Form 10-K for the year ended December 31, 2012, our most recent Quarterly Reports on Form 10-Q for the quarter ended March 31, 2013, filed on May 7, 2013, for the quarter ended June 30, 2013, filed on August 8, 2013, for the quarter ended September 30, 2013, filed on November 12, 2013 and our other public filings.
- 9 -

In addition, the price of our common stock could also be affected by market factors, including rebalancing of portfolios by institutional investors and resetting of indexes.  Our common stock is listed for quotation on The NASDAQ Capital Market.  During the twelve month period ended December 31, 2013, the price of our common stock ranged from $1.50 to $3.05.  We expect the price of our common stock to remain volatile.  The average daily trading volume in our common stock varies significantly.  For the twelve month period ended December 31, 2013, the average daily trading volume in our common stock was approximately 549,650 shares and the average number of transactions per day was approximately 1,505.  The instability observed in our daily volume and number of transactions per day may affect the ability of our stockholders to sell their shares in the public market at prevailing prices.

In the past, following periods of volatility in the market price of the securities of companies in our industry, securities class action litigation has often been instituted against companies in our industry.  Even if securities class actions that we may face in the future are ultimately determined to be meritless or unsuccessful, they involve substantial costs and a diversion of management attention and resources, which could negatively impact our business.

If we raise additional capital in the future, your ownership in us could be diluted.

Any issuance of equity we may undertake in the future to raise additional capital could cause the price of our common stock to decline, or require us to issue shares at a price that is lower than that paid by holders of our common stock in the past, which would result in those newly issued shares being dilutive. If we obtain funds through a credit facility or through the issuance of debt or preferred securities, these securities would likely have rights senior to your rights as a common shareholder, which could impair the value of our common stock.

A sale of a substantial number of shares of our common stock may cause the price of our common stock to decline.

Sales of a substantial number of shares of our common stock in the public market following this offering could cause the market price of our common stock to decline.  A substantial majority of the outstanding shares of our common stock are, and all of the shares sold in this offering upon issuance will be, freely tradable without restriction or further registration under the Securities Act unless these shares are purchased by affiliates.  In addition, as of September 30, 2013, 15,666,164 shares of our common stock are issuable upon exercise of outstanding options and warrants and the vesting of restricted stock units granted by us, which also have been registered or registered for resale on registration statements filed with the Securities and Exchange Commission.  The outstanding options have a weighted average exercise price of $7.96 per share and expire through August 2023.  The outstanding warrants have a weighted average exercise price of $4.51 per share and expire between November 2013 and February 2019.    The restricted stock units vest in June 2014 and expire in June 2023.  If our stock price increases, the holders of such options, warrants and convertible securities may exercise such securities and could sell a large number of these shares into the market.  These additional issuances and sales could cause the market price of our common stock to decline.  We also have entered into an At-the-Market Equity Offering Sales Agreement (ATM Program) with Stifel, Nicolaus & Company, Incorporated (Stifel), under which Stifel, as our exclusive agent, at our discretion and at such times that we determine from time to time, may sell until February 11, 2016, up to a maximum of $25,000,000 of shares of our common stock.  Use of these equity programs would increase our outstanding, which could cause the market price of our common stock to decline.

We cannot predict whether future issuances of shares of our common stock or the availability of shares for resale in the open market will decrease the market price per share of our common stock.  Sales of substantial amounts of our shares of common stock in the public market, or even the perception that such sales might occur, could adversely affect the market price of the shares of our common stock.

FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein and therein, contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.  The forward-looking statements are only predictions and provide our current expectations or forecasts of future events and financial performance and may be identified by the use of forward-looking terminology, including the terms “believes,” “estimates,” “anticipates,” “expects,” “plans,” “intends,” “may,” “will” or “should” or, in each case, their negative, or other variations or comparable terminology, though the absence of these words does not necessarily mean that a statement is not forward-looking.  Forward-looking statements include all matters that are not historical facts and include, without limitation, statements concerning our business strategy, outlook, objectives, future milestones, plans, intentions, goals, and future financial condition, including the period of time for which our existing resources will enable us to fund our operations.  Forward-looking statements also include our financial, clinical, manufacturing and distribution plans and our expectations and timing related to commercialization of SURFAXIN® , the development and potential regulatory plan to secure marketing authorization for AEROSURF® and our other potential pipeline products, if approved; our research and development programs, including planning for development activities, anticipated timing of clinical trials and potential development milestones; plans for the manufacture of drug products, active pharmaceutical ingredients (APIs) and materials and medical devices; and plans regarding potential strategic alliances and other collaborative arrangements to develop, manufacture and market our products.

We intend that all forward-looking statements be subject to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.  Forward-looking statements are subject to many risks and uncertainties that could cause actual results to differ materially from any future results expressed or implied by the forward-looking statements.  We caution you therefore against relying on any of these forward-looking statements.  They are neither statements of historical fact nor guarantees or assurances of future performance.  Examples of the risks and uncertainties include, but are not limited to:

risks relating to the ability of our sales and marketing organization to effectively introduce SURFAXIN in the U.S. and, if approved, our other product candidates, in a timely manner, if at all; and that we may not succeed in developing a sufficient market awareness of our products or that our product candidates may not gain market acceptance by physicians, patients, healthcare payers and others in the medical community;

the risk that, if we fail to successfully commercialize SURFAXIN as planned, and if we do not achieve revenues consistent with our expectations, our revenues would be limited, and we may be unable to secure additional capital when needed, whether from strategic alliances or other sources, to continue our commercial and medical affairs activities, as well as our research and development programs and our operations would be impaired, which ultimately could have a material adverse effect on our business, financial condition and results of operations;

the risks that, although the U.S. Food and Drug Administration (FDA) has cleared our investigational new drug (IND) application for the initial phase of our AEROSURF® phase 2 clinical program and we are initiating activities, our clinical program nevertheless may be interrupted, delayed, or fail, which will harm our business;

the risk that we may be unable to enter into strategic alliances and/or collaboration agreements that would assist and support us in markets outside the U.S. with the development of our KL4 surfactant pipeline products, beginning with AEROSURF, and including the development of our lyophilized KL4 surfactant, and, if approved, commercialization of AEROSURF in markets outside the U.S.; and support the commercialization of SURFAXIN in countries where regulatory approval is facilitated by the information contained in the SURFAXIN new drug application (NDA) approved by the FDA; and potentially support the development and, if approved, commercialization, of our other pipeline products;

risks relating to our research and development activities, which among other things involve time-consuming and expensive preclinical studies and potentially multiple clinical trials that may be subject to potentially significant delays or regulatory holds or fail;

- 11 -

risks related to our efforts to gain regulatory approval, in the U.S. and elsewhere, for our drug product and medical device candidates, including AEROSURF, and our lyophilized KL4 surfactant that we expect will be the drug component of AEROSURF and potentially be developed as a life cycle extension of SURFAXIN under the name SURFAXIN LS™ ;

risks relating to the transfer of our manufacturing technology to contract manufacturing organizations (CMOs) and assemblers;

risks relating to our and our CMOs' ability to manufacture our KL4 surfactant, in liquid and lyophilized dosage forms, which must be processed in an aseptic environment and tested using sophisticated and extensive analytical methodologies and quality control release and stability tests, for both commercial and research and development activities;

risks relating to our ability to develop and manufacture combination drug/device products based on our CAG technology, for preclinical and clinical studies of our product candidates and, if approved, for commercialization;

the risk that we, our CMOs or any of our third-party suppliers, many of which are single-source providers, may encounter problems or delays in manufacturing our KL4 surfactant drug products and the APIs used in the manufacture of our drug product, CAG devices and other materials on a timely basis or in an amount sufficient to support the commercial introduction of SURFAXIN and the AFECTAIR device for infants, our aerosol-conducting airway connector, as well as our research and development activities for AEROSURF and our other product candidates;

the risks that, even if we succeed with the commercial introduction of SURFAXIN, we nevertheless in the future will require, but may be unable to secure, significant additional capital to continue our operations, fund our debt service and support our research and development activities, including expensive and time-consuming clinical trials, until such time, if ever, that our revenues from all sources are sufficient to offset our cash outflows. To the extent that we raise such capital through additional financings, such additional financings could result in equity dilution;

risks relating to our pledge of substantially all of our assets to secure our obligations under our loan facility (Deerfield Facility) with Deerfield Management Company, L.P., which could make it more difficult for us to secure additional capital to satisfy our obligations and require us to dedicate cash flow to payments for debt service, which would reduce the availability of our cash flow to fund working capital, capital expenditures and other investment;

risks relating to our ability to manage our growth effectively and timely modify our business strategy as needed to respond to developments in our commercial operations and research and development activities, as well as our business, our industry and other factors;

risks relating to our plans to secure marketing and distribution capabilities in certain markets through third-party strategic alliances and/or marketing alliances and/or distribution arrangements, that could require us to give up rights to our drug products, drug product candidates and drug delivery technologies;

- 12 -

risks relating to our research and development activities, which among other things involve time-consuming and expensive preclinical studies and potentially multiple clinical trials that may be subject to potentially significant delays or regulatory holds or fail;

risks relating to the rigorous regulatory approval processes, including pre-filing activities, required for approval of any drug, combination drug-device product or medical device that we may develop, whether independently, with strategic development partners or pursuant to collaboration arrangements;

the risk that we and the FDA or other regulatory authorities will not be able to agree on matters raised during the regulatory review process, or that we may be required to conduct significant additional activities to potentially gain approval of our product candidates, if ever;

the risk that the FDA or other regulatory authorities may not accept, or may withhold or delay consideration of, any applications that we may file, or may not approve our applications or may limit approval of our products to particular indications or impose unanticipated label limitations;

the risk that market conditions, the competitive landscape or other factors may make it difficult to launch and profitably sell our products;

risks that reimbursement and health care reform may adversely affect us or that our products will not be accepted by physicians and others in the medical community;

the risk that changes in the national or international political and regulatory environment may make it more difficult to gain FDA or other regulatory approval of our drug product and medical device candidates;

the risk that we may be unable to maintain compliance with continued listing requirements of The NASDAQ Capital Market, which could increase the probability that our stock will be delisted, which could cause our stock price to decline;

the risks that we may be unable to maintain and protect the patents and licenses related to our products and that other companies may develop competing therapies and/or technologies;

the risks that we may become involved in securities, product liability and other litigation and that our insurance may be insufficient to cover costs of damages and defense;

the risk that we our strategic partners or collaborators will be unable to attract and retain key employees, including qualified scientific, professional and other personnel, in a competitive market for skilled personnel, which could have a material adverse effect on our commercial, research and development activities and our operations; and

other risks and uncertainties detailed in “Risk Factors” and in the documents incorporated by reference in this report.

Pharmaceutical, biotechnology and medical technology companies have suffered significant setbacks conducting clinical trials, even after obtaining promising earlier trial results.  Data obtained from such clinical trials are susceptible to varying interpretations, which could delay, limit or prevent regulatory approval.  After gaining approval of a drug product, pharmaceutical and biotechnology companies face considerable challenges in marketing and distributing their products, and may never become profitable.
- 13 -

The forward-looking statements contained in this report or the documents incorporated by reference herein speak only as of their respective dates.  Factors or events that could cause our actual results to differ may emerge from time to time and it is not possible for us to predict them all.  Except to the extent required by applicable laws, rules or regulations, we do not undertake any obligation to publicly update any forward-looking statements or to publicly announce revisions to any of the forward-looking statements, whether as a result of new information, future events or otherwise.

SELLING STOCKHOLDERS

This prospectus relates to the resale by the selling stockholders of shares of common stock that we may issue upon exercise of the Warrants we issued to the Deerfield Entities on December 3, 2013.  We are filing the registration statement of which this prospectus is a part pursuant to the provisions of the Registration Rights Agreement we entered into with the Deerfield Entities on February 13, 2013.

The following table presents information regarding the Deerfield Entities and the shares that any of the Deerfield Entities may offer and sell from time to time under this prospectus.  This table is prepared based on information supplied to us by the selling stockholders, and reflects holdings as of January 15, 2014.  As used in this prospectus, the term “selling stockholder” includes the Deerfield Entities and any donees, pledges, transferees or other successors in interest of the Deerfield Entities.  The number of shares in the column “Number of Shares Being Offered” represents all of the shares that the selling stockholders may offer under this prospectus.  The selling stockholders may sell some, all or none of its shares.  We do not know how long the selling stockholders will hold the shares before selling them, and we currently have no agreements, arrangements or understandings with the selling stockholders regarding the sale of any of the shares.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, as amended, and includes shares of common stock with respect to which Deerfield Entities have voting and investment power.

The 9.985% limitation is disregarded for purposes of this table, and the number of shares of common stock listed as beneficially owned do not reflect this limitation.

PLAN OF DISTRIBUTION

We are registering 4,660,000 shares of common stock under this prospectus on behalf of the selling stockholders.  The selling stockholders will pay any brokerage commissions and similar selling expenses attributable to the sale of the shares. We will not receive any of the proceeds from the sale of the shares by the selling stockholders. However, upon a cash exercise of the Warrants by the selling stockholders, we will receive a per share exercise price of $2.81. If the Warrants are exercised in a cashless exercise, we will not receive any proceeds from the exercise of the Warrants.

These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. To the extent any of the selling stockholders gift, pledge or otherwise transfer the shares offered hereby, such transferees may offer and sell the shares from time to time under this prospectus, provided that this prospectus has been amended under Rule 424(b)(3) or other applicable provision of the Securities Act to include the name of such transferee in the list of selling stockholders under this prospectus.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein: ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction; purchases by a broker-dealer as principal and resale by the broker-dealer for its account; an exchange distribution in accordance with the rules of the applicable exchange; privately negotiated transactions; short sales; through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; a combination of any such methods of sale; and any other method permitted pursuant to applicable law.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the Warrants by payment of cash, however, we will receive the exercise price of the Warrants.

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.
- 16 -

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying any applicable prospectus delivery requirements of the Securities Act.

We have agreed to indemnify the selling stockholders against certain liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

The selling stockholders and any broker dealers that act in connection with the sale of the shares may be deemed to be “underwriters” as the term is defined in Section 2(11) of the Securities Act. Consequently, any commissions received by these broker dealers and any profit on the resale of the shares sold by them while acting as principals might be deemed to be underwriting discounts or commissions under the Securities Act.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that Rule.

We currently have authorized 150 million shares of common stock, par value $0.001 per share.  As of January 15, 2014, there were 84,638,219 shares of common stock outstanding, which does not include:

Subject to any preferential rights of any preferred stock created by our Board of Directors, as a holder of our common stock you are entitled to such dividends as our Board of Directors may declare from time to time out of funds that we can legally use to pay dividends.  The holders of common stock possess exclusive voting rights, except to the extent our Board of Directors specifies voting power for any preferred stock that, in the future, may be issued.

As a holder of our common stock, you are entitled to one vote for each share of common stock and do not have any right to cumulate votes in the election of directors.  Upon our liquidation, dissolution or winding-up, you will be entitled to receive on a proportionate basis any assets remaining after provision for payment of creditors and after payment of any liquidation preferences to holders of preferred stock.  Holders of our common stock have no preemptive rights and no conversion rights or other subscription rights.  There are no redemption or sinking fund provisions applicable to our common stock.  All the outstanding shares of common stock are, and the shares offered by this prospectus, when issued and paid for, will be, validly issued, fully paid and nonassessable.  Our common stock is quoted on The NASDAQ Capital Market under the symbol “DSCO”.

Stockholder Rights Plan

The summary description of the Rights set out herein does not purport to be complete, and is qualified in its entirety by reference to the terms and provisions of our Shareholder Rights Agreement, dated as of February 6, 2004 (Certain values in the following discussion gave been adjusted to give effect to a 1-for-15 reverse stock split that was effected in December 2010).

On February 6, 2004, our Board of Directors adopted a shareholder rights agreement (the Rights Agreement).  Pursuant to the Rights Agreement our Board of Directors (i) declared that each stockholder of record as of the close of business on February 6, 2004, would be issued a dividend of one preferred stock purchase right (a Right) for each share of our common stock held by such stockholder and (ii) determined that each share of common stock issued by us after such date through the Final Expiration Date (as defined below) shall be issued with a tandem Right.  Each Right represents the right to purchase fifteen ten-thousandths (0.0015) of a share of our Series A Junior Participating Cumulative Preferred Stock (Series A Preferred) at an exercise price equal to $50 per one ten-thousandths of a share (as the same may be adjusted, the Exercise Price).  The Rights shall be evidenced by certificates for our common stock until the earlier to occur of:
- 18 -

·            10 days following a public announcement that a person or group of affiliated or associated persons (with certain exceptions, an Acquiring Person) have acquired beneficial ownership of 15% or more of the outstanding shares of our common stock; and

·            10 business days (or such later date as may be determined by action of the Board of Directors before such time as any person or group of affiliated persons becomes an Acquiring Person) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of which would result in the beneficial ownership by a person or group of 15% or more of the outstanding shares of Common Stock (the earlier of such dates being called the Distribution Date).

The Rights are not exercisable until the Distribution Date.  Until a Right is exercised, the holder thereof, as such, will have no rights as a Discovery stockholder, including, without limitation, the right to vote or to receive dividends.

The Rights will expire upon the close of business on February 6, 2014 (the “Final Expiration Date”), unless the Rights are earlier redeemed or exchanged by us, in each case as described below.

The shares of Series A Preferred purchasable upon exercise of the Rights will be entitled, when, as and if declared, to a minimum preferential quarterly dividend payment of 10,000 times the per share amount of dividends declared on our common stock.  If no common stock dividend is declared in a quarter, a preferred stock quarterly dividend of $1.00 per share will be required.  Upon our liquidation, holders of Series A Preferred will be entitled to a preferential distribution payment of at least 10,000 times the payment made per share of common stock.  Each share of Series A Preferred will entitle the holder to 10,000 votes, voting together with our common stock.  Upon any merger, consolidation or other transaction in which shares of our common stock are converted or exchanged, the holders of Series A Preferred will be entitled to receive 10,000 times the amount of consideration received per share of our common stock in respect of such transaction.  The Rights are protected by customary anti-dilution provisions.

Because of the nature of the Series A Preferred dividend and liquidation rights, the fair market value of each one ten-thousandths of a share of Series A Preferred purchasable upon exercise of each Right should approximate the fair market value of one share of our common stock.  If any person or group of affiliated or associated persons becomes an Acquiring Person, each holder of a Right, (other than Rights beneficially owned by the Acquiring Person, which become void), will have the right to receive upon exercise and payment of the then current Exercise Price, that number of shares of our common stock having a market value of two times the Exercise Price.

If, after a person or group has become an Acquiring Person, we are acquired in a merger or other business combination transaction, or 50% or more of our consolidated assets or earning power are sold, proper provision will be made so that each holder of a Right (other than Rights beneficially owned by an Acquiring Person, which become void) will thereafter have the right to receive, upon exercise at the then current Exercise Price, that number of shares of common stock of the person with whom we engaged in the foregoing transaction (or its parent), which at the time of such transaction will have a market value of two times the Exercise Price.  In lieu of exercise, our Board of Directors may exchange the Rights (other than Rights owned by an Acquiring Person, which become void), in whole or in part, for such securities or other property or rights as the Board may determine, including any class or series of our common stock or preferred stock.

At any time before the time an Acquiring Person becomes such, our Board of Directors may redeem the Rights in whole, but not in part, at a price of $.015 per Right, subject to adjustment.

We may amend the Rights to the extent and on the conditions set out in the Rights Agreement.

Anti-Takeover Provisions

As a corporation organized under the laws of the State of Delaware, we are subject to Section 203 of the General Corporation Law of the State of Delaware, which restricts our ability to enter into business combinations with an interested stockholder or a stockholder owning 15% or more of our outstanding voting stock, or that stockholder’s affiliates or associates, for a period of three years.  These restrictions do not apply if:
- 19 -

·            before becoming an interested stockholder, our Board of Directors approves either the business combination or the transaction in which the stockholder becomes an interested stockholder;

·            upon consummation of the transaction in which the stockholder becomes an interested stockholder, the interested stockholder owns at least 85% of our voting stock outstanding at the time the transaction commenced, subject to exceptions; or

·            on or after the date a stockholder becomes an interested stockholder, the business combination is both approved by our Board of Directors and authorized at an annual or special meeting of our stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Number of Directors; Removal

Our By-Laws provide that our Board of Directors shall consist of at least three directors and may consist of such larger number as may be determined, from time-to-time, by the Board of Directors.  Our By-laws provide that directors may be removed with or without cause by the affirmative vote of holders of a majority of the total voting power of all outstanding securities.

This provision and the Board of Directors’ right to issue shares of our preferred stock from time to time, in one or more classes or series without stockholder approval are intended to enhance the likelihood of continuity and stability in the composition of the policies formulated by our Board of Directors.  These provisions are also intended to discourage some tactics that may be used in proxy fights.

The Transfer Agent and Registrar for our common stock is Continental Stock Transfer & Trust Company.

Item 15.
Indemnification of Directors and Officers

Article Eighth of our Restated Certificate of Incorporation limits the liability of directors to the maximum extent permitted by Delaware law.  Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for (i) any breach of their duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the General Corporation Law of the State of Delaware or (iv) any transaction from which the director derives an improper personal benefit.

Our By-Laws provide that we shall indemnify our directors and officers, the directors and officers of any of our subsidiaries and any other individuals acting as directors or officers of any other corporation at our request, to the fullest extent permitted by law.

We have entered into indemnification agreements with certain of our executive officers and directors containing provisions that may require us, among other things, to indemnify them against liabilities that may arise by reason of their status or service as officers or directors, as applicable, other than liabilities arising from willful misconduct of a culpable nature and to advance certain expenses incurred as a result of any proceeding against them as to which they could be indemnified.  We have obtained limited directors’ and officers’ liability insurance.

These provisions in our Restated Certificate of Incorporation and our By-Laws do not eliminate the officers’ and directors’ fiduciary duty, and in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law.  In addition, each officer and director will continue to be subject to liability for breach of their duty of loyalty to us for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to the officer or director and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law.  The provisions also do not affect an officer’s or director’s responsibilities under any other law, such as the federal securities laws or state or federal environmental laws.

Item 17.
Undertakings

(a)           The undersigned registrant hereby undertakes:

(1)           To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)           To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii)           To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.  Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii)           To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the registration statement is on Form S-3, Form S-8, or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)           That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)           To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)           The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)           Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.


(d)           The undersigned registrant hereby undertakes that:

(1)           For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)           For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.


SIGNATURES

Pursuant to the requirement of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the Township of Warrington, Commonwealth of Pennsylvania, on the 22nd of January, 2014.

Re:
Sale of Warrant Shares
Registration Statement on Form S-3

Ladies and Gentlemen:

In our capacity as counsel to Discovery Laboratories, Inc., a Delaware corporation (the “Company”), the Company has asked us to render this opinion in connection with a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”) (as so filed and amended, the “Registration Statement”), initially filed with the Securities and Exchange Commission (the “Commission”) on January 22, 2014, including a related prospectus the (“Prospectus”) covering the registration for resale of up to 4,660,000 shares (the “Warrant Shares”) of common stock, par value $0.001 per share, of the Company (the “Common Stock”) issuable upon exercise of certain warrants held by certain stockholders (the “Warrants”).

We are delivering this opinion to you at your request in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

In connection with rendering this opinion, we have examined and are familiar with (i) the Company’s Amended and Restated Certificate of Incorporation, (ii) the Company’s By-Laws, (iii) the Registration Statement, including the prospectus contained therein, (iv) corporate proceedings of the Company relating to the Warrants and the Warrant Shares and (v) such other instruments and documents as we have deemed relevant under the circumstances.

In making the aforesaid examinations, we have assumed the genuineness of all signatures and the conformity to original documents of all copies furnished to us as original or photostatic copies. We have also assumed that the corporate records furnished to us by the Company include all corporate proceedings taken by the Company to date.

Based upon the foregoing, and in reliance thereon, and subject to the qualifications, limitations and exceptions stated herein, we are of the opinion, having due regard for such legal considerations as we deem relevant, that the Warrant Shares have been duly authorized by the Company and, when issued in accordance with the terms set forth in the Registration Statement and the Prospectus, and, when issued and paid for in accordance with the terms of the Warrants, will be validly issued, fully paid and nonassessable.


 
Discovery Laboratories, Inc.
