ITEM 5. OTHER EVENTS On July 8, 2004, Discovery Laboratories, Inc. (the "Registrant"), issued a press release to announce the completion of a Committed Equity Financing Facility Arrangement ("CEFF") with Kingsbridge Capital Limited ("Kingsbridge") pursuant to which Kingsbridge has committed to finance up to $75 million of capital to support the Registrant's future growth. The CEFF is embodied in a Common Stock Purchase Agreement filed herewith as Exhibit 10.1 and a Registration Rights Agreement filed herewith as Exhibit 10.2. Subject to certain limitations, from time to time under the CEFF, the Registrant can require Kingsbridge to purchase newly-issued shares of the Registrant's common stock, par value $.001 per share (the "Common Stock"), over the course of a 15-trading day period. Subject to limited exceptions, on each trading day of each such financing period, Kingsbridge is required to purchase shares of Common Stock for an aggregate purchase price equal to 1/15 of the applicable financing amount. The Registrant has the right to determine the exact timing, amount and price of any and all financings under the CEFF, subject to certain conditions and limitations. The CEFF allows the Registrant to raise capital as required, at the time, price and in amounts deemed suitable to the Registrant, during the three-year period following the effectiveness of the registration statement to be filed by the Registrant with the Securities and Exchange Commission ("SEC"). In connection with the CEFF, the Registrant issued to Kingsbridge a warrant, a copy of which is filed herewith as Exhibit 4.1, to purchase up to 375,000 shares of Common Stock at an exercise price equal to $12.0744 per share (the "Warrant"). The Warrant may not be exercised if and to the extent that the shares to be issued to Kingsbridge upon such exercise, when aggregated with other shares of Common Stock beneficially owned, or deemed beneficially owned, by Kingsbridge, would cause Kingsbridge to own more than 9.9% of the outstanding shares of Common Stock on the date of such exercise. The Warrant is exercisable for five years commencing on January 7, 2005. The warrant must be exercised for cash, except in limited circumstances. Pursuant to the CEFF, the Registrant may access up to and including $18.75 million per 15-day financing period. The Registrant is not obligated to utilize any of the $75 million available under the CEFF and there are no minimum commitment or minimum use penalties. The Registrant may not access the CEFF unless and until the SEC declares effective the registration statement to be filed by the Registrant covering the resale of the shares of Common Stock issuable in connection with the CEFF and the shares of Common Stock underlying the Warrant. Each draw down will be priced over a 15-trading day financing period with the Registrant controlling the minimum acceptable purchase price for any shares to be issued to Kingsbridge during that time. The purchase price for the shares of Common Stock pursuant to the CEFF shall reflect discounts ranging from 6% to 10% of the average market price of the Common Stock during the applicable financing period, with the reduced discounts applying if the price of the Common Stock is equal to $9.01 or more. However, Kingsbridge shall not be required to purchase any shares of Common Stock on any day of a financing period if and to the extent that such purchase would cause Kingsbridge to purchase a number of shares of Common Stock which, when aggregated with other shares of Common Stock then beneficially owned, or deemed beneficially owned, by Kingsbridge, would result in Kingsbridge owning more than 9.9% of the outstanding shares of Common Stock on such day. There must be at least five trading days between individual financing periods, and individual financing are limited to certain maximum amounts depending on the then current market capitalization of the Registrant. 2

The CEFF does not contain any restrictions on the Registrant's operating activities, automatic pricing resets or minimum market volume restrictions nor prohibit the Registrant from conducting additional debt or equity financings, including PIPEs, shelf offerings, secondary offerings or any other fixed future-priced securities. Throughout the term of the CEFF, Kingsbridge is restricted from engaging in any transaction intended to reduce its economic risk of owning shares of the Registrant's common stock including, without limitation, the purchase of any option or contract to sell, selling "short" or "short against the box", or otherwise entering into any other security transaction the purpose of which is to hedge its risk of ownership of the Common Stock. The description of the terms and conditions of the CEFF and the Warrant and the rights and obligations of the Registrant and Kingsbridge in connection therewith are qualified by reference in their entirety to the definitive terms and conditions of the Common Stock Purchase Agreement, the Registration Rights Agreement and the Warrant, forms of which are filed as exhibits to this Report.

the Company for $12.0744 per share  (subject to adjustment  as provided  herein)
and an aggregate  purchase  price equal to  $4,527,900.  (Hereinafter,  (i) said
common stock,  $.001 par value per share, of the Company,  is referred to as the
"COMMON STOCK," (ii) the shares of Common Stock  purchasable  hereunder or under
any other  Warrant (as  hereinafter  defined)  are  referred to as the  "WARRANT

                                       5

1. EXERCISE OF WARRANT. (a) This Warrant may be exercised in whole at any time, or in part from time to time, commencing on January 7, 2005, and prior to 5:00 P.M., New York City time, on January 6, 2010, by the Holder by: (i) the surrender of this Warrant (with the subscription form at the end hereof duly executed) at the address set forth in Section 9(a) hereof, together with proper payment of the Aggregate Warrant Price, or the proportionate part thereof if this Warrant is exercised in part, with payment for the Warrant Shares made by certified or official bank check payable to the order of the Company; or (ii) the surrender of this Warrant (with the cashless exercise form at the end hereof duly executed) (a "CASHLESS EXERCISE") at the address set forth in Section 10(a) hereof; provided, that a Cashless Exercise may only be effected by the Holder and the Company during an Ineffective Period or a Blackout Period (as such terms are defined in the Registration Rights Agreement) and where the Holder may not sell all the Warrant Shares to be issued in connection with such Cashless Exercise in a single transaction pursuant to Rule 144 promulgated under the Securities Act of 1934 as of the date of such Cashless Exercise. In the event of a Cashless Exercise in accordance with this Section 1(a), Holder shall exchange this Warrant for that number of Warrant Shares subject to such Cashless Exercise multiplied by a fraction, the numerator of which shall be the difference between (A) the "Current Market Price," which is defined as the closing sale price of the Common Stock on the Trading Day (as defined in the Purchase Agreement) prior to the date of such surrender or, in case no such reported sales take place on such Trading Day, the average of the last reported bid and asked prices of the Common Stock on such Trading Day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing sale price of the Common Stock as reported by Nasdaq, or other similar organization if Nasdaq is no longer reporting such information, or, if the Common Stock is not reported on Nasdaq, the high per share sale price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined in good faith by the Board of Directors of the Company (the "BOARD") and (B) the Per Share Exercise Price, and the denominator of which shall be the Current Market Price. For purposes of any computation under this Section 1(a), the Current Market Price shall be based on the Trading Day immediately prior to the Cashless Exercise. The "Closing Sales Price" shall be the reported per share closing sales price, regular way, of the Common Stock on the Nasdaq SmallCap Market (or on the Nasdaq National Market or a national securities exchange, as the case may be) at 4:00 PM New York Time on the applicable Trading Day. If, at any time after July 7, 2006, a registration statement on Form S-1 under the Securities Act of 1933 (the "ACT") or such other form as deemed appropriate by counsel to the Company for the registration for the resale by the Holder of (x) the shares of Common Stock of the Company that may be purchased under the Purchase Agreement, (y) the Warrant Shares or (z) any securities issued or issuable with respect to any of the foregoing by way of exchange, stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization or otherwise, has been declared effective by the Commission and remains effective, the Company may permit or require the Holder to effect a Cashless Exercise in connection with the exercise of this Warrant. 6

(b) If this Warrant is exercised in part, this Warrant must be exercised for a number of whole shares of Common Stock and the Holder is entitled to receive a new Warrant covering the Warrant Shares that have not been exercised and setting forth the proportionate part of the Aggregate Warrant Price applicable to such Warrant Shares. (c) Upon surrender of this Warrant, the Company will (i) issue a certificate or certificates in the name of the Holder, or its nominee, for the largest number of whole shares of the Common Stock to which the Holder shall be entitled and, if this Warrant is exercised in whole, in lieu of any fractional share of Common Stock to which the Holder shall be entitled, pay to the Holder cash in an amount equal to the fair value of such fractional share (determined in such reasonable manner as the Board shall determine) and (ii) deliver the other securities and properties receivable upon the exercise of this Warrant, or the proportionate part thereof if this Warrant is exercised in part, pursuant to the provisions of this Warrant. (d) The Holder may not exercise this Warrant such that the number of Warrant Shares to be received pursuant to such exercise aggregated with all other shares of Common Stock then owned by the Holder beneficially or deemed beneficially owned by the Holder would result in the Holder owning more than 9.9% of all of such Common Stock as would be outstanding on such Exercise Date, as determined in accordance with Section 13(d) of the Exchange Act of 1934 and the rules and regulations promulgated thereunder. 2. RESERVATION OF WARRANT SHARES; LISTING. The Company agrees and covenants that, prior to the expiration of this Warrant, the Company shall at all times (i) have authorized and in reserve, and shall keep available, solely for issuance and delivery upon the exercise of this Warrant, the shares of Common Stock and other securities and properties receivable upon the exercise of this Warrant and shall be validly issued and non-assessable, free and clear of all restrictions on sale or transfer, other than under Federal or state securities or blue sky laws, and free and clear of all preemptive rights and rights of first refusal and (ii) use its best efforts to keep the Warrant Shares authorized for listing on the Nasdaq National Market, the SmallCap Market or any national securities exchange on which the Common Stock is traded. 3. PROTECTION AGAINST DILUTION. (a) If the Company, at any time while this Warrant is unexpired and not exercised in full, (i) reclassifies or changes its Common Stock (other than a change in par value or as a result of a subdivision or combination of Common Stock issuable upon exercise of the Warrant) or (ii) consolidates, merges or effects a mandatory share exchange with or into another corporation (other than a merger or mandatory share exchange with another corporation in which the Company is a continuing corporation and that does not result in any reclassification or change, other than a change in par value or as a result of a subdivision or combination of Common Stock issuable upon exercise of the Warrant) at any time while this Warrant is unexpired and not exercised in full, then in any such event the Company, or such successor or purchasing corporation, as the case may be, shall, without payment of any additional consideration therefore, amend this Warrant or issue a new Warrant providing that the Holder shall have rights not less favorable to the Holder than those then applicable to this Warrant and to receive upon exercise under such 7

amendment of this Warrant or new Warrant, in lieu of each share of Common Stock theretofore issuable upon exercise of the Warrant hereunder, the kind and amount of shares of stock, other securities, money or property receivable upon such reclassification, change, consolidation, merger or mandatory share exchange by the holder of one share of Common Stock issuable upon exercise of the Warrant had the Warrant been exercised immediately prior to such reclassification, change, consolidation, merger or mandatory share exchange. Such amended Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 3. The provisions of this Section 3(a) shall similarly apply to successive reclassifications, changes, consolidations, mergers, mandatory share exchanges and sales and transfers. (b) If the Company, at any time while this Warrant is unexpired and not exercised in full, shall subdivide its Common Stock, the Per Share Warrant Price shall be proportionately reduced as of the effective date of such subdivision, or, if the Company shall take a record of holders of its Common Stock for the purpose of so subdividing, as of such record date, whichever is earlier. If the Company, at any time while this Warrant is unexpired and not exercised in full, shall combine its Common Stock, the Per Share Warrant Price shall be proportionately increased as of the effective date of such combination, or, if the Company shall take a record of holders of its Common Stock for the purpose of so combining, as of such record date, whichever is earlier. (c) If the Company, at any time while this Warrant is unexpired and not exercised in full, shall pay a dividend or make a distribution on the outstanding shares of Common Stock in shares of its Common Stock, then, as of the effective date of payment of such dividend or distribution, the number and kind of shares of Common Stock receivable upon exercise of this Warrant shall be proportionately adjusted so that the Holder shall thereafter be entitled to receive the aggregate number of shares of Common Stock which, if such Warrant had been exercised immediately prior to such time, it would have owned upon such exercise and been entitled to receive by virtue of such dividend or distribution. The provisions of this Section 3(c) shall not apply under any of the circumstances for which an adjustment is provided in Sections 3(a) or 3(b). (d) No adjustment in the Per Share Warrant Price shall be required unless such adjustment would require an increase or decrease of at least $0.05 per share of Common Stock; provided, however, that any adjustments which by reason of this Section 3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further, however, the Company shall be entitled to make such reductions in the Per Share Warrant Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. All calculations under this Section 3 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. (e) Upon the expiration of any rights, options, warrants or conversion privileges with respect to the issuance of which an adjustment to the Per Share Warrant Price had been made, if such shall not have been exercised, the number of Warrant Shares purchasable upon exercise of this Warrant, to the extent this Warrant has not then been exercised, shall, upon such expiration, be readjusted and shall thereafter be such as they would have been had they been originally adjusted (or had the original adjustment not been required, as the case may be) 8

on the basis of (A) the fact that Common Stock, if any, actually issued or sold upon the exercise of such rights, options, warrants or conversion privileges and (B) the fact that such shares of Common Stock, if any, were issued or sold for the consideration actually received by the Company upon such exercise plus the consideration, if any, actually received by the Company for the issuance, sale or grant of all such rights, options, warrants or conversion privileges whether or not exercised; provided, however, that no such readjustment shall have the effect of decreasing the number of Warrant Shares purchasable upon exercise of this Warrant by an amount in excess of the amount of the adjustment initially made in respect of the issuance, sale or grant of such rights, options, warrants or conversion privileges. 4. FULLY PAID STOCK; TAXES. The Warrant Shares delivered upon the exercise of this Warrant shall at the time of such delivery, be duly authorized, validly issued and outstanding, fully paid and non-assessable, and not subject to preemptive rights or rights of first refusal, and the Company will take all such actions as may be necessary to assure that the par value, if any, per Warrant Share is at all times equal to or less than the then Per Share Warrant Price. The Company shall pay all documentary, stamp or similar taxes and other similar governmental charges that may be imposed with respect to the issuance or delivery of any Warrant Shares (other than income taxes); provided, however, that if the Warrant Shares are to be delivered in a name other than the name of the Holder, no such delivery shall be made unless the person requesting the same has paid to the Company the amount of transfer taxes or charges incident thereto, if any. 5. INVESTMENT INTENT; LIMITED TRANSFERABILITY. (a) The Holder represents, by accepting this Warrant, that it understands that this Warrant and any securities obtainable upon exercise of this Warrant have not been registered for sale under Federal or state securities or blue sky laws and are being offered and sold to the Holder pursuant to one or more exemptions from the registration requirements of such securities laws. In the absence of an effective registration of such securities or an exemption therefrom, any certificates for such securities shall bear a legend substantially similar to the legend set forth on the first page of this Warrant. The Holder understands that it must bear the economic risk of its investment in this Warrant and any securities obtainable upon exercise of this Warrant for an indefinite period of time, as this Warrant and such securities have not been registered under Federal or state securities or blue sky laws and therefore cannot be sold unless subsequently registered under such laws, unless an exemption from such registration is available. (b) The Holder agrees and acknowledges that this Warrant, or any portion thereof, and any such securities will not be sold or otherwise transferred unless (i) a registration statement with respect to such transfer is effective under the Act and any applicable state securities or blue sky laws or (ii) such sale or transfer is made pursuant to one or more exemptions from the Act. (c) The Holder agrees and acknowledges that in addition to the limitations set forth in the Registration Rights Agreement with respect to Registrable Securities, this Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Act and the applicable state securities or blue sky laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose. The Company may treat the registered Holder of this Warrant as it appears on the Company's books at any time as the Holder for all purposes. The Company shall 9

permit any Holder of a Warrant or its duly authorized attorney, upon written request during ordinary business hours, to inspect and copy or make extracts from its books showing the registered holders of Warrants. All Warrants issued upon the transfer or assignment of this Warrant will be dated the same date as this Warrant, and all rights of the holder thereof shall be identical to those of the Holder. (d) The Holder represents that it has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the Warrants or the exercise of the Warrants and the finance operations and business of the Company and (ii) the opportunity to request such additional information which the Company possesses or can acquire without unreasonable effort or expense. Nothing contained in this Section 5(d) shall alter, amend or change Holder's reliance on the representations, covenants or warranties contained herein. (e) The Holder represents that it did not (i) receive or review any advertisement, article, notice or other communication published in a newspaper or magazine or similar media or broadcast over television or radio, whether closed circuit, or generally available; or (ii) attend any seminar, meeting or investor or other conference whose attendees were, to such Holder's knowledge, invited by any general solicitation or general advertising. (f) The Holder represents that it is an "accredited investor" within the meaning of Regulation D promulgated under the Act. Such Holder is acquiring the Warrants for its own account and not with a present view to, or for sale in connection with, any distribution thereof in violation of the registration requirements of the Act, without prejudice, however, to such Holder's right, subject to the provisions of the Purchase Agreement, the Registration Rights Agreement and this Warrant, at all times to sell or otherwise dispose of all or any part of the Warrants and Warrant Shares. (g) The Holder represents that it, either by reason of the Holder's business or financial experience or the business or financial experience of its professional advisors (who are unaffiliated with and who are not compensated by the Company or any affiliate, finder or selling agent of the Company, directly or indirectly), has such sophistication, knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment in the Company and the capacity to protect the Holder's interests in connection with the transactions contemplated by this Warrant, the Purchase Agreement and the Registration Rights Agreement. (h) The Holder represents that it has the ability to bear the economic risks of its investment for an indefinite period of time and could afford a complete loss of its investment. (i) The Holder agrees and acknowledges that the representations made by the Holder in this Section 5 are conditions to the exercise of the Warrant. (j) Nothing in this Section 5 shall affect in any way the Holder's obligations under any agreement to comply with all applicable securities laws upon resale of the Warrant Shares. 10

6. LOSS, ETC., OF WARRANT. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver to the Holder a new Warrant of like date, tenor and denomination. 7. HOLDER NOT STOCKHOLDER. This Warrant does not confer upon the Holder any right to vote on or consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, nor any other rights or liabilities as a stockholder, prior to the exercise hereof; this Warrant does, however, require certain notices to Holders as set forth herein. 8. NOTICES OF RECORD DATE, ETC. If the Company shall propose at any time to effect or to establish (i) a record date for the holders of the Common Stock for the purpose of entitling them to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares or stock of any class or any other securities or to receive any other right or (ii) any voluntary or involuntary dissolution, liquidation or dissolution of the Company, then notice of any such proposed action shall be mailed to the Holders not less than 10 days prior to such event. 9.

All notices, demands, requests, consents, approvals, and other communications required or permitted hereunder shall be in writing and, unless otherwise specified herein, shall be (i) personally served, (ii) deposited in the mail, registered or certified, return receipt requested, postage prepaid, (iii) delivered by reputable air courier service with charges prepaid or (iv) transmitted by hand delivery, telegram or facsimile, addressed as set forth below or to such other address as such party shall have specified most recently by written notice given in accordance herewith.

This Warrant shall be governed by and construed in accordance with the laws of the State of New York without giving effect to the principles of conflicts of law thereof. 13. AMENDMENT, WAIVER, ETC. Except as expressly provided herein, neither this Warrant nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the party against whom enforcement of any such amendment, waiver, discharge or termination is sought. 12

The number of Shares purchased by the Investor with respect to each Draw Down shall be determined and settled on a periodic basis in respect of the applicable Draw Down Pricing Period.

Each date on which settlement of the purchase and sale of Shares occurs hereunder being referred to as a "Settlement Date." The Investor shall provide the Company with delivery instructions for the Shares to be issued at each Settlement Date at least two (2) Trading Days in advance of such Settlement Date (except to the extent previously provided).

Section 3.07. Delivery of Shares; Payment of Draw Down Amount. On each Settlement Date, the Company shall deliver the Shares purchased by the Investor to the Investor or its designees via book-entry through the Depositary Trust Company to an account designated by the Investor in accordance with Section 3.06 upon receipt of payment therefor from the Investor to the Company's designated account by wire transfer of immediately available funds. Section 3.08. Threshold Price. For each Trading Day during a Draw Down Pricing Period that the Draw Down Discount Price is less than the Threshold Price, no Shares shall be purchased or sold in respect of such Trading Day, the total amount of the Draw Down Amount in respect of such Draw Down Pricing Period shall be reduced by one fifteenth (1/15th) and the amount of the Draw Down Amount not so purchased or sold shall continue to be available in future Draw Downs and as part of the Maximum Commitment Amount. If trading in the Common Stock is suspended for any reason for more than three (3) consecutive or non-consecutive hours during any Trading Day during a Draw Down Pricing Period, the Draw Down Discount Price shall be deemed to be less than the Threshold Price for that Trading Day. Section 3.09. Other Issuances. If during any Draw Down Pricing Period, the Company shall issue any shares of Common Stock in connection with a Prohibited Transaction without the prior written consent of the Investor, then the applicable Draw Down Notice shall be deemed null and void and the Investor shall promptly return to the Company any and all Shares transferred to the Investor in respect of any Settlement Date(s) during such Draw Down Pricing Period and the Company shall promptly thereafter pay to the Investor by wire transfer of immediately available funds to an account designated by the Investor that portion of the applicable Draw Down Amount paid to the Company in respect of such Settlement Date(s). Section 3.10. Failure to Deliver Shares. If on any Settlement Date, the Company fails to deliver the Shares to be purchased by the Investor, and such failure is not cured within ten (10) Trading Days following the date on which the Investor delivered payment for such Shares, the Company shall pay to the Investor on demand in cash by wire transfer of immediately available funds to an account designated by the Investor the "Make Whole Amount;" provided, however, that in the event that the Company is prevented from delivering Shares in respect of any such Settlement Date in a timely manner by any fact or circumstance that is reasonably within the control of, or directly attributable to, the Investor, then such ten (10) Trading Day period shall be automatically extended until such time as such fact or circumstance is cured. As used herein, the Make Whole Amount shall be an amount equal to the sum of (i) the Draw Down Amount actually paid by the Investor in respect of such Shares plus (ii) an amount equal to the actual loss suffered by the Investor in respect of sales to subsequent purchasers, pursuant to transactions entered into before the Settlement Date, of the Shares that were required to be delivered by the Company, which shall be based upon documentation reasonably satisfactory to the Company demonstrating the difference (if greater than zero) between (A) the price per share paid by the Investor to purchase such number of shares of Common Stock necessary for the Investor to meet its share delivery obligations to such subsequent purchasers minus (B) the average Draw Down Discount Price during the 28

Upon the terms and subject to the conditions and limitations set forth in the Registration Rights Agreement, the Registration Statement shall have previously become effective and shall remain effective and (i) neither the Company nor the Investor shall have received notice that the Commission has issued or intends to issue a stop order with respect to the Registration Statement or that the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or intends or has threatened to do so (unless the Commission's concerns have been addressed and the Investor is reasonably satisfied that the Commission no longer is considering or intends to take such action), and (ii) no other suspension of the use or withdrawal of the effectiveness of the Registration Statement or the Prospectus shall exist. Section 7.05. No Knowledge. The Company shall have no Knowledge of any event more likely than not to have the effect of causing the Registration Statement with respect to the resale of the Registrable Securities by the Investor to be suspended or otherwise ineffective (which event is more likely than not to occur within fifteen (15) Trading Days following the Trading Day on which a Draw Down Notice is delivered). Section 7.06. No Suspension. Trading in the Common Stock shall not have been suspended by the Commission or the applicable Principal Market and trading in securities generally as reported on the applicable Principal Market shall not have been suspended or limited. Section 7.07. No Injunction.

Section 7.08. No Proceedings or Litigation. No action, suit or proceeding before any arbitrator or any governmental authority shall have been commenced, and no investigation by any governmental authority shall have been threatened, against the Company or any subsidiary, or any of the officers, directors or Affiliates of the Company or any subsidiary seeking to enjoin, prevent or change the transactions contemplated by this Agreement. Section 7.09. Section 16 Limitation. On each Settlement Date, the number of Shares then to be purchased by the Investor shall not exceed the number of such shares that, when aggregated with all other Registrable Securities then owned by the Investor beneficially or deemed beneficially owned by the Investor, would result in the Investor owning more than 9.9% of all of such Common Stock as would be outstanding on such Settlement Date, as determined in accordance with Section 16 of the Exchange Act. For purposes of this Section 7.09, in the event that the amount of Common Stock outstanding as determined in accordance 40

with Section 16 of the Exchange Act and the regulations promulgated thereunder is greater on a Settlement Date than on the date upon which the Draw Down Notice associated with such Settlement Date is given, the amount of Common Stock outstanding on such Settlement Date shall govern for purposes of determining whether the Investor, when aggregating all purchases of Common Stock made pursuant to this Agreement and, if any, Warrant Shares, would own more than 9.9% of the Common Stock following such Settlement Date. Section 7.10. Sufficient Shares Registered for Resale. The Company shall have sufficient Shares, calculated using the closing trade price of the Common Stock as of the Trading Day immediately preceding such Draw Down Notice, registered under the Registration Statement to issue and sell the Shares purchased in connection with each Draw Down Notice. Section 7.11. Warrant. The Warrant shall have been duly executed, delivered and issued to the Investor, and the Company shall not be in default in any material respect under any of the provisions thereof, provided that any refusal by or failure of the Company to issue and deliver Warrant Shares in respect of any exercise (in whole or in part) thereof shall be deemed to be material for the purposes of this Section 7.11. Section 7.12. Opinion of Counsel. The Investor shall have received an opinion of counsel to the Company, dated as of the Closing Date, in form and substance reasonably satisfactory to the Investor and its counsel substantially in the form attached hereto as Exhibit D. ARTICLE VIII LEGENDS Section 8.01. Legends. Unless otherwise provided below, each certificate representing Registrable Securities will bear the following legend (the "Legend"): THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION THAT IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS CERTIFICATE IS THE BENEFICIARY OF CERTAIN OBLIGATIONS OF THE COMPANY SET FORTH IN A COMMON STOCK PURCHASE AGREEMENT BETWEEN DISCOVERY LABORATORIES, INC., AND KINGSBRIDGE CAPITAL LIMITED DATED AS OF JULY 7, 2004. A COPY OF THE PORTION OF THE AFORESAID AGREEMENT EVIDENCING SUCH OBLIGATIONS MAY BE OBTAINED FROM THE COMPANY'S EXECUTIVE OFFICES. 41

As soon as practicable after the execution and delivery hereof, but in any event within five (5) Trading Days thereafter, the Company shall issue to the transfer agent for its Common Stock (and to any substitute or replacement transfer agent for its Common Stock upon the Company's appointment of any such substitute or replacement transfer agent) instructions, with a copy to the Investor. It is the intent and purpose of such instructions, as provided therein, to require the transfer agent for the Common Stock from time to time upon transfer of Registrable Securities by the Investor to issue certificates evidencing such Registrable Securities free of the Legend during the following periods and under the following circumstances and without consultation by the transfer agent with the Company or its counsel and without the need for any further advice or instruction or documentation to the transfer agent by or from the Company or its counsel or the Investor, unless an opinion of Investor's counsel is reasonably required by the transfer agent or the Company: (a) At any time after the Closing Date to the extent accompanied by a notice requesting the issuance of certificates free of the Legend; provided, that (i) the Company is reasonably able to confirm to the transfer agent that the Registration Statement shall then be effective and (ii) if reasonably requested by the transfer agent the Investor confirms to the transfer agent that the Investor has complied with the prospectus delivery requirement under the Securities Act. (b) At any time upon any surrender of one or more certificates evidencing Registrable Securities that bear the Legend, to the extent accompanied by a notice requesting the issuance of new certificates free of the Legend to replace those surrendered and containing representations that (i) the Investor is permitted to dispose of such Registrable Securities without limitation as to amount or manner of sale pursuant to Rule 144(k) under the Securities Act and there is no requirement for the Investor to deliver a prospectus or (ii) the Investor has sold, pledged or otherwise transferred or agreed to sell, pledge or otherwise transfer such Registrable Securities in a manner other than pursuant to an effective registration statement, to a transferee who shall upon such transfer be entitled to freely tradable securities. Section 8.02. No Other Legend or Stock Transfer Restrictions. No legend other than the one specified in Section 8.01 has been or shall be placed on the share certificates representing the Common Stock issued to the Investor and no instructions or "stop transfer orders," so called "stock transfer restrictions," or other restrictions have been or shall be given to the Company's transfer agent with respect thereto other than as expressly set forth in this Article VIII. ARTICLE IX TERMINATION Section 9.01. Term. Unless otherwise terminated in accordance with Section 9.02 below, this Agreement shall terminate upon the expiration of the Commitment Period. 42

Section 9.02. Other Termination. (a) The Investor may terminate this Agreement upon (x) one (1) day's notice if the Company enters into any Prohibited Transaction as set forth in Section 6.08 without the Investor's prior written consent, or (y) one (1) day's notice within ten (10) Trading Days after the Investor obtains actual knowledge that an event resulting in a Material Adverse Effect has occurred; provided, however, that the Investor shall be deemed to possess such actual knowledge within five (5) Trading Days after such event has been publicly disclosed by the Company in accordance with its periodic reporting requirements under the Exchange Act. (b) The Investor may terminate this Agreement upon one (1) day's notice to the Company at any time in the event that the Registration Statement is not declared effective in accordance with the Registration Rights Agreement. (c) The Company may terminate this Agreement upon one (1) day's notice; provided, however, that the Company shall not terminate this Agreement pursuant to this Section 9.02(c) during any Draw Down Pricing Period; provided, further, that in the event of any termination of this Agreement by the Company hereunder, so long as the Investor owns Shares purchased hereunder and/or Warrant Shares, unless all of such shares of Common Stock may be resold by the Investor without registration and without any time, volume or manner limitations pursuant to Rule 144(k) (or any similar provision then in effect) under the Securities Act, the Company shall not suspend or withdraw the Registration Statement or otherwise cause the Registration Statement to become ineffective, or voluntarily delist the Common Stock from the applicable Principal Market, without listing the Common Stock on another Principal Market. (d) Each of the parties hereto may terminate this Agreement upon one (1) day's notice if the other party has breached a material representation, warranty or covenant to this Agreement and such breach is not remedied within ten (10) Trading Days after notice of such breach is delivered to the breaching party. (e) The obligation of the Investor to purchase shares of Common Stock shall terminate permanently in the event that there shall occur any stop order or suspension of effectiveness of the Registration Statement for an aggregate of thirty (30) calendar days during the Commitment Period. (f) In the event of termination by the Company or the Investor, written notice thereof shall forthwith be given to the other party and the transactions contemplated by this Agreement shall be terminated without further action by either party. If this Agreement is terminated as provided in Section 9.01 or 9.02 herein, this Agreement shall become void and of no further force and effect, except as provided in Section 12.14. Nothing in this Section 9.03 shall be deemed to release the Company or the Investor from any liability for any breach under this Agreement or to impair the rights of the Company and the Investor to compel specific performance by the other party of its obligations under this Agreement. 43

ARTICLE X INDEMNIFICATION Section 10.01. Indemnification. (a) Except as otherwise provided in this Article X, unless disputed as set forth in Section 10.02, the Company agrees to indemnify, defend and hold harmless the Investor and its Affiliates and their respective officers, directors, agents, employees, subsidiaries, partners, members and Controlling persons (each, an "Investor Indemnified Party"), to the fullest extent permitted by law from and against any and all Damages directly resulting from or directly arising out of any breach of any representation or warranty, covenant or agreement by the Company in this Agreement, the Registration Rights Agreement or the Warrant; provided, however, that the Company shall not be liable under this Article X to an Investor Indemnified Party to the extent that such Damages resulted or arose from the breach by an Investor Indemnified Party of any representation, warranty, covenant or agreement of an Investor Indemnified Party contained in this Agreement, the Registration Rights Agreement or the Warrant or the gross negligence, recklessness, willful misconduct or bad faith of an Investor Indemnified Party. The parties intend that any Damages subject to indemnification pursuant to this Article X will be net of insurance proceeds (which the Investor Indemnified Party agrees to use commercially reasonable efforts to recover). Accordingly, the amount which the Company is required to pay to any Investor Indemnified Party hereunder (a "Company Indemnity Payment") will be reduced by any insurance proceeds actually recovered by or on behalf of any Investor Indemnified Party in reduction of the related Damages. In addition, if an Investor Indemnified Party receives a Company Indemnity Payment required by this Article X in respect of any Damages and subsequently receives any such insurance proceeds, then the Investor Indemnified Party will pay to the Company an amount equal to the Company Indemnity Payment received less the amount of the Company Indemnity Payment that would have been due if the insurance proceeds had been received, realized or recovered before the Company Indemnity Payment was made. (b) Except as otherwise provided in this Article X, unless disputed as set forth in Section 10.02, the Investor agrees to indemnify, defend and hold harmless the Company and its subsidiaries and Affiliates and their respective officers, directors, agents, employees, subsidiaries, partners, members and Controlling persons (each, a "Company Indemnified Party"), to the fullest extent permitted by law from and against any and all Damages directly resulting from or arising out of any breach of any representation or warranty, covenant or agreement by the Investor in this Agreement, the Registration Right Agreement or the Warrant; provided, however, that the Investor shall not be liable under this Article X to a Company Indemnified Party to the extent that such Damages resulted or arose from the breach by a Company Indemnified Party of any representation, warranty, covenant or agreement of a Company Indemnified Party contained in this Agreement, the Registration Right Agreement or the Warrant or gross negligence, recklessness, willful misconduct or bad faith of a Company Indemnified Party. The parties intend that any Damages subject to indemnification pursuant to this Article X will be net of insurance proceeds (which the Company agrees to use commercially reasonable efforts to recover). Accordingly, the amount which the Investor is required to pay to any Company Indemnified Party hereunder (an "Investor Indemnity Payment") will be reduced by any insurance proceeds theretofore actually recovered by or on behalf of any Company Indemnified Party in reduction of the related Damages. In addition, if a Company Indemnified Party receives a Investor Indemnity Payment required by this Article X in respect of any Damages and subsequently receives insurance such proceeds, then the Company Indemnified Party will pay to the Investor an amount equal to the Investor Indemnity Payment received less the amount of the Investor Indemnity Payment that would have been due if the insurance proceeds had been received, realized or recovered before the Investor Indemnity Payment was made. 44

Section 10.02. Notification of Claims for Indemnification. Each party entitled to indemnification under this Article X (an "Indemnified Party") shall, promptly after the receipt of notice of the commencement of any claim against such Indemnified Party in respect of which indemnity may be sought from the party obligated to indemnify such Indemnified Party under this Article X (the "Indemnifying Party"), notify the Indemnifying Party in writing of the commencement thereof. Any such notice shall describe the claim in reasonable detail. The failure of any Indemnified Party to so notify the Indemnifying Party of any such action shall not relieve the Indemnifying Party from any liability which it may have to such Indemnified Party (a) other than pursuant to this Article X or (b) under this Article X unless, and only to the extent that, such failure results in the Indemnifying Party's forfeiture of substantive rights or defenses or the Indemnifying Party is prejudiced by such delay. The procedures listed below shall govern the procedures for the handling of indemnification claims. (a) Any claim for indemnification for Damages that do not result from a Third Party Claim as defined in the following paragraph, shall be asserted by written notice given by the Indemnified Party to the Indemnifying Party. Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such thirty (30) day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to make payment as set forth in Section 10.01. If such Indemnifying Party does not respond within such thirty (30) day period or rejects such claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as specified in this Agreement, including the dispute resolution provisions set forth in Section 10.03 below. (b) If an Indemnified Party shall receive notice or otherwise learn of the assertion by a person or entity not a party to this Agreement of any threatened legal action or claim (collectively a "Third Party Claim"), with respect to which an Indemnifying Party may be obligated to provide indemnification, the Indemnified Party shall give such Indemnifying Party written notice thereof within twenty (20) days after becoming aware of such Third Party Claim. (c) An Indemnifying Party may elect to defend (and, unless the Indemnifying Party has specified any reservations or exceptions, to seek to settle or compromise) at such Indemnifying Party's own expense and by such Indemnifying Party's own counsel, any Third Party Claim. Within thirty (30) days after the receipt of notice from an Indemnified Party (or sooner if the nature of such Third Party Claim so requires), the Indemnifying Party shall notify the Indemnified Party whether the Indemnifying Party will assume responsibility for defending such Third Party Claim, which election shall specify any reservations or exceptions. If such Indemnifying Party does not respond within such thirty (30) day period or rejects such claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as specified in this Agreement, including the dispute resolution provisions set forth in Section 10.03 below. In case any such Third Party Claim shall be brought against any Indemnified Party, and it shall notify the Indemnifying Party of the commencement thereof, the 45

Indemnifying Party shall be entitled to assume the defense thereof at its own expense, with counsel satisfactory to such Indemnified Party in its reasonable judgment; provided, however, that any Indemnified Party may, at its own expense, retain separate counsel to participate in such defense at its own expense. Notwithstanding the foregoing, in any Third Party Claim in which both the Indemnifying Party, on the one hand, and an Indemnified Party, on the other hand, are, or are reasonably likely to become, a party, such Indemnified Party shall have the right to employ separate counsel and to control its own defense of such claim if, in the reasonable opinion of counsel to such Indemnified Party, either (x) one or more significant defenses are available to the Indemnified Party that are not available to the Indemnifying Party or (y) a conflict or potential conflict exists between the Indemnifying Party, on the one hand, and such Indemnified Party, on the other hand, that would make such separate representation advisable; provided, however, that in such circumstances the Indemnifying Party (i) shall not be liable for the fees and expenses of more than one counsel to all Indemnified Parties and (ii) shall reimburse the Indemnified Parties for such reasonable fees and expenses of such counsel incurred in any such Third Party Claim, as such expenses are incurred, provided that the Indemnified Parties agree to repay such amounts if it is ultimately determined that the Indemnifying Party was not obligated to provide indemnification under this Article X. The Indemnifying Party agrees that it will not, without the prior written consent of the Indemnified Party, settle, compromise or consent to the entry of any judgment in any pending or threatened claim relating to the matters contemplated hereby (if any Indemnified Party is a party thereto or has been actually threatened to be made a party thereto) unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising or that may arise out of such claim. The Indemnifying Party shall not be liable for any settlement of any claim effected against an Indemnified Party without the Indemnifying Party's written consent, which consent shall not be unreasonably withheld, conditioned or delayed. The rights accorded to an Indemnified Party hereunder shall be in addition to any rights that any Indemnified Party may have at common law, by separate agreement or otherwise (subject, however, to the provisions of Section 10.03 below); provided, however, that notwithstanding the foregoing or anything to the contrary contained in this Agreement, nothing in this Article X (other than Section 10.03) shall restrict or limit any rights that any Indemnified Party may have to seek equitable relief. ARTICLE XI ARBITRATION Section 11.01. Arbitration. Any dispute under this Agreement, the Registration Rights Agreement or the Warrant shall be submitted to arbitration (including, without limitation, pursuant to this Article X) by sending written notice of such election to the other party or parties clearly marked "Arbitration Demand". Thereupon such dispute shall be arbitrated in accordance with the terms and conditions of this Article XI. Notwithstanding the foregoing, either party, subject to the terms, conditions and provisions of Section 12.12, may apply to a court of competent jurisdiction for a temporary restraining order, a preliminary injunction or other equitable relief to preserve the status quo or prevent irreparable harm. Section 11.02. Board of Arbitration. Each of the Company and the Investor shall select one (1) member of the Board of Arbitration and the third member shall be selected by mutual agreement of the other members, or if the other members fail to reach agreement on a third member within twenty (20) days after their selection, such third member shall thereafter be selected by the American Arbitration Association upon application made to it for such purpose by either party to this Agreement. 46

Section 11.03. Counterclaims. Nothing contained herein shall operate to prevent either party from asserting counterclaim(s) in any arbitration commenced in accordance with this Agreement, and any such party need not comply with the procedural provisions of this Article XI in order to assert such counterclaim(s). Section 11.04. Procedures. The arbitration shall be filed with the office of the American Arbitration Association ("AAA") located in Wilmington, Delaware or such other AAA office as the parties may agree upon (without any obligation to so agree). The arbitration shall be conducted pursuant to the Commercial Arbitration Rules of AAA as in effect at the time of the arbitration hearing, such arbitration to be completed in a 60-day period. In addition, the following rules and procedures shall apply to the arbitration: (a) The Board of Arbitration shall meet on consecutive business days in the city in which the arbitration was filed, and shall reach and render a decision (concurred in by a majority of the members of the Board of Arbitration) which shall be in writing and state the findings the facts and conclusions of law upon which the decision is based, shall be final and binding upon the parties, who shall forthwith comply after receipt thereof. In connection with rendering its decisions, the Board of Arbitration shall adopt and follow such rules and procedures as a majority of the members of the Board of Arbitration deems necessary or appropriate. To the extent practical, decisions of the Board of Arbitration shall be rendered no more than thirty (30) calendar days following commencement of proceedings with respect thereto. The Board of Arbitration shall cause its written decision to be delivered to the parties hereto that are involved in such arbitration. Any decision made by the Board of Arbitration (either prior to or after the expiration of such thirty (30) calendar day period) shall be final, binding and conclusive on the Indemnified Party and the Indemnifying Party and entitled to be enforced to the fullest extent permitted by law and entered in any court of competent jurisdiction. Each party submits itself to the jurisdiction of any such court, but only for the entry and enforcement to judgment with respect to the decision of the arbitrator hereunder. (b) The Board of Arbitration shall have the sole authority to decide whether or not any dispute between the parties is arbitrable and whether the party presenting the issues to be arbitrated has satisfied the conditions precedent to such party's right to commence arbitration as required by this Article XI. (c) The Board of Arbitration shall have the power to grant all legal and equitable remedies (including, without limitation, specific performance) and award compensatory damages provided by applicable law, but shall not have the power or authority to award punitive damages. No party shall seek punitive damages in relation to any matter under, arising out of, or in connection with or relating to this Agreement in any other forum. (d) Each party to any arbitration shall bear its own expense in relation thereto, including but not limited to such party's attorneys' fees, if any, and the expenses and fees of the Board of Arbitration shall be paid initially one-half by each of the Company and the Investor, but then apportioned between the Company and the Investor in the same proportion as the portion of 47

the related claim determined by the Board of Arbitration to be payable to the injured party bears to the portion of such claim determined not to be so payable; provided, however, that each party shall bear the costs incurred in connection with any dispute brought by such party that the Board of Arbitration determines to have been brought in bad faith. (e) Except as provided in the last sentence of Section 11.01, the provisions of this Article XI shall be a complete defense to any suit, action or proceeding instituted in any federal, state or local court or before any administrative tribunal with respect to any dispute arising with regard to this Agreement. Any party commencing a lawsuit in violation of this Article XI shall pay the costs of the other party, including, without limitation, reasonable attorney's fees and defense costs. ARTICLE XII MISCELLANEOUS Section 12.01. Fees and Expenses. The Company shall be solely responsible for (i) all reasonable attorneys fees and expenses incurred by the Investor in connection with the preparation, negotiation, execution and delivery of this Agreement, the Registration Rights Agreement and the Warrant up to an aggregate maximum of $40,000, (ii) all reasonable fees and expenses incurred by the Investor in connection with any amendments, modifications or waivers of this Agreement or incurred in connection with the Investor's enforcement of this Agreement, including, without limitation, all reasonable attorneys fees and expenses, (iii) all reasonable due diligence expenses incurred by the Investor during the term of this Agreement up to aggregate maximum amount of $7,500 per calendar quarter; provided, however, that the payments set forth in this clause (iii) shall not apply if the Company sells shares of Common Stock to the Investor with an aggregate purchase price equal to at least $10,000,000; provided, further, that upon the Company selling shares of Common Stock to the Investor with an aggregate purchase price equal to at least $10,000,000, the Investor shall promptly refund to the Company any amounts that were actually paid to the Investor prior to such date, and (iv) all stamp or other similar taxes and duties, if any, levied in connection with issuance of the Shares pursuant hereto; provided, however, that in each of the above instances the Investor shall provide customary supporting invoices or similar documentation in reasonable detail describing such expenses. The Investor shall reimburse all reasonable due diligence expenses incurred by the Company in connection with this transaction prior to the date of this Agreement. Section 12.02. Reporting Entity for the Common Stock. The reporting entity relied upon for the determination of the trading price or trading volume of the Common Stock on any given Trading Day for the purposes of this Agreement shall be Bloomberg or any successor thereto.

Acknowledgement Regarding the Investor's Purchase of Shares The Investor is acting solely in the capacity of an arm's length investor with respect to this Agreement and the transactions contemplated hereby.

                         REGISTRATION RIGHTS AGREEMENT


      This REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of July 7,
2004 (the "Effective Date"), is by and between DISCOVERY LABORATORIES, INC. (the
"Company"), and KINGSBRIDGE CAPITAL LIMITED (the "Investor").

      WHEREAS,  the Company and the  Investor  have  entered  into that  certain
Common Stock  Purchase  Agreement,  dated as of the  Effective  Date hereof (the
"Purchase Agreement"),  pursuant to which the Company may issue to the Investor,
from time to time, up to $75 million worth of shares of Common Stock as provided
for therein;

      WHEREAS,  pursuant to the terms of, and in partial  consideration  for the
Investor  entering into, the Purchase  Agreement,  the Company has issued to the
Investor  a  warrant,  exercisable  from  time to time  within  five  (5)  years
following the six-month  anniversary of the date of issuance (the "Warrant") for
the purchase of an aggregate of up to 375,000  shares of Common Stock at a price
specified in such Warrant;

      WHEREAS,  pursuant to the terms of, and in partial  consideration for, the
Investor's  agreement  to enter into the  Purchase  Agreement,  the  Company has
agreed to provide the Investor with certain  registration rights with respect to
the Registrable  Securities (as defined in the Purchase  Agreement) as set forth
herein;

      NOW,  THEREFORE,  in consideration of the premises,  the  representations,
warranties, covenants and agreements contained herein, in the Warrant and in the
Purchase Agreement,  and for other good and valuable consideration,  the receipt
and sufficiency of which is hereby  acknowledged,  intending to be legally bound

not defined  herein shall have the respective  meanings  ascribed to them in the
Purchase Agreement):

                                   ARTICLE I

                              REGISTRATION RIGHTS

Section 1.1. REGISTRATION STATEMENT.

            (a) Filing of the Registration Statement. Upon the terms and subject
to the conditions set forth in this  Agreement,  the Company shall file with the
Commission,  within  forty-five  (45) calendar days after the Effective  Date, a
registration  statement on Form S-3 under the  Securities Act or such other form
as deemed  appropriate  by counsel to the Company for the  registration  for the
resale  by  the  Investor  of  the  Registrable  Securities  (the  "Registration
Statement").  For purposes of this  Agreement,  the "Filing Date" shall refer to
the date on which the Company files the Registration Statement.

                                       54

(b) Effectiveness of the Registration Statement. The Company shall use commercially reasonable efforts (i) to have the Registration Statement declared effective by the Commission as soon as reasonably practicable, but in any event no later than forty-five (45) calendar days after the Filing Date, or ninety (90) calendar days after the Filing Date in the event that the Commission reviews the Registration Statement, following the date that the Registration Statement is filed and (ii) to ensure that the Registration Statement remains in effect throughout the term of this Agreement as set forth in Section 4.2, subject to the terms and conditions of this Agreement. (c) Regulatory Disapproval. The contemplated effective date for the Registration Statement as described in Section 1.1(b) shall be extended without default or liquidated damages hereunder or under the Purchase Agreement in the event that the Company's failure to obtain the effectiveness of the Registration Statement on a timely basis results from (i) the failure of the Investor to provide the Company with information requested by the Company and necessary to complete the Registration Statement by the Filing Date, (ii) the Commission's disapproval of the structure of the transactions contemplated by the Purchase Agreement, (iii) the Commission failing to respond within a customary time period to the filing of the Registration Statement or any post filing communications from the Company, or (iv) events or circumstances that are not in any way attributable to the Company; provided, that the Company has complied and continues to comply with its obligation to use commercially reasonable efforts to cause the Registration Statement to become effective. In the event of clause (ii) above, the parties agree to cooperate with one another in good faith to arrive at a resolution acceptable to the Commission. (d) Failure to Maintain Effectiveness of Registration Statement. In the event the Company fails to maintain the effectiveness of the Registration Statement throughout the period set forth in Section 4.2, other than temporary suspensions as set forth in Section 1.1(e) or 2.1(n), and the Investor holds any Registrable Securities at any time during the period of such ineffectiveness (an "Ineffective Period"), the Company shall pay to the Investor in immediately available funds into an account designated by the Investor an amount (which shall in no event exceed $2.5 million) equal to the product of (x) the total number of Registrable Securities issued to the Investor under the Purchase Agreement and owned by the Investor at any time during such Ineffective Period and (y) the result, if greater than zero, obtained by subtracting the VWAP on the Trading Day immediately following the last day of such Ineffective Period from the VWAP on the Trading Day immediately preceding the day on which any such Ineffective Period began; provided, however, that the foregoing payments shall not apply in respect of Registrable Securities that (i) are otherwise freely tradable by the Investor, including, but not limited to, under Rule 144 promulgated under the Securities Act (as such rule may be amended from time to time, "Rule 144") or (ii) the Company offers to repurchase from the Investor for a per share purchase price equal to the VWAP on the Trading Day immediately preceding the day on which any such Ineffective Period began. (e) Deferral or Suspension During a Blackout Period. If in the good faith judgment of the Company, following consultation with legal counsel (which may be internal counsel), it would be detrimental to the Company or its stockholders for the Registration Statement to be filed or for resales of Registrable Securities to be made pursuant to the Registration Statement due to (i) the existence of a material development or potential material development involving the Company that the Company would be obligated to disclose in the Registration Statement, which disclosure would be premature or otherwise inadvisable at such time or would have a Material Adverse Effect on the Company 55

or its stockholders or (ii) a proposed filing of or use of an existing registration statement in connection with a Company-initiated registration of any class of its equity securities, which, in the good faith judgment of the Company, would adversely effect or require premature disclosure of the filing or use of such Company-initiated registration (notice thereof, a "Blackout Notice"), the Company shall have the right to (A) immediately defer such filing for a period of not more than sixty (60) days beyond the date on which the Registration Statement was otherwise required hereunder to be filed or (B) suspend use of the Registration Statement by the Investor for a period of not more than thirty (30) days (any such deferral or suspension period, a "Blackout Period"). The Investor acknowledges that it would be seriously detrimental to the Company and its stockholders for the Registration Statement to be filed or used, or remain in effect, during a Blackout Period and therefore essential to defer such filing, or suspend the use or the effectiveness thereof, during such Blackout Period and agrees to cease any disposition of the Registrable Securities during such Blackout Period. The Company may not utilize any of its rights under this Section 1.1(e) to defer the filing of a Registration Statement (or suspend its use or effectiveness) more than six (6) times in any twelve (12) month period. In the event that, within fifteen (15) Trading Days following any Settlement Date, the Company gives a Blackout Notice to the Investor and the VWAP on the Trading Day immediately preceding such Blackout Period ("Old VWAP") is greater than the VWAP on the first Trading Day following such Blackout Period on which the Investor may sell its Registrable Securities pursuant to an effective Registration Statement ("New VWAP"), then the Company shall pay to the Investor, by wire transfer of immediately available funds to an account designated by the Investor, the "Blackout Amount." For the purposes of this Agreement, Blackout Amount means a percentage equal to: (1) seventy-five percent (75%) if such Blackout Notice is delivered prior to the fifth (5th) Trading Day following such Settlement Date; (2) fifty percent (50%) if such Blackout Notice is delivered on or after the fifth (5th) Trading Day following such Settlement Date, but prior to the tenth (10th) Trading Day following such Settlement Date; (3) twenty-five percent (25%) if such Blackout Notice is delivered on or after the tenth (10th) Trading Day following such Settlement Date, but prior to the fifteenth (15th) Trading Day following such Settlement Date; and (4) zero percent (0%) thereafter of: the product of (i) the number of Registrable Securities purchased by the Investor pursuant to the most recent Draw Down and actually held by the Investor immediately prior to the Blackout Period and (ii) the result obtained by subtracting the New VWAP from the Old VWAP; provided, however, that (i) no Blackout Amount in respect of any Blackout Period shall exceed $2.5 million, (ii) no Blackout Amount shall be payable under this Section 1.1(e) in the event that the Registrable Securities are eligible for resale under Rule 144 during the Blackout Period and (iii) no Blackout Amount shall be payable under this Section 1.1(e) in the event that the Company offers to repurchase from the Investor for a per share purchase price equal to the VWAP on the Trading Day immediately preceding the day on which any such Ineffective Period began. (f) Liquidated Damages. (1) The Company and the Investor hereto acknowledge and agree that the amounts payable under Sections 1.1(d) and 1.1(e) and the Blackout Shares deliverable under Section 1.1(e) above shall constitute liquidated damages and not penalties. The parties further acknowledge that (i) the amount of loss or damages likely to be incurred by the Investor is incapable or is difficult to precisely estimate, (ii) the amounts specified in such subsections bear a reasonable proportion and are not plainly or grossly disproportionate to the probable loss likely to be incurred in connection with any failure by the Company to obtain or maintain the effectiveness of the 56

Registration Statement, (iii) one of the reasons for the Company and the Investor reaching an agreement as to such amounts was the uncertainty and cost of litigation regarding the question of actual damages and (iv) the Company and the Investor are sophisticated business parties and have been represented by sophisticated and able legal and financial counsel and negotiated this Agreement at arm's length. (g) The Company and the Investor agree and acknowledge that the amounts payable under Sections 1.1(d) and 1.1(e), as applicable, constitute the Investor's sole remedy with respect to the Company's failure to maintain the effectiveness for the Registration Statement or for any deferral or suspension of the Registration Statement during a Blackout Period as discussed in such Sections. The Investor further agrees and acknowledges that assuming the payment of any amount by the Company, as set forth in such Sections, the Company's failure to maintain the effectiveness of the Registration Statement or for any deferral or suspension of the Registration Statement during a Blackout Period, as applicable, shall not constitute a material breach or default of any obligation of the Company to the Investor. (h) Additional Registration Statements. In the event and to the extent that the Registration Statement fails to register a sufficient amount of Common Stock necessary for the Company to issue and sell to the Investor and the Investor to purchase from the Company all of the Registrable Securities to be issued, sold and purchased under the Purchase Agreement and the Warrant, the Company shall prepare and file with the Commission an additional registration statement or statements in order to effectuate the purpose of this Agreement, the Purchase Agreement and the Warrant. ARTICLE II REGISTRATION PROCEDURES Section 2.1. FILINGS; INFORMATION. The Company shall use commercially reasonable efforts to effect the registration with respect to the sale of the Registrable Securities by the Investor in accordance with the intended methods of disposition thereof. Without limiting the foregoing, the Company in each such case will use commercially reasonable efforts to perform the following acts as expeditiously as possible, but in no event later than the deadline, if any, prescribed therefor in this Agreement: (a) Subject to Section 1.1(e), the Company shall: (i) prepare and file with the Commission the Registration Statement; (ii) use commercially reasonable efforts to cause such filed Registration Statement to become and to remain effective (pursuant to Rule 415 under the Securities Act or otherwise); (iii) prepare and file with the Commission such amendments and supplements to the Registration Statement and the Prospectus used in connection therewith (the "Prospectus")as may be necessary to keep such Registration Statement effective for the time period prescribed by Section 4.2 and in order to effectuate the purpose of this Agreement, the Purchase Agreement and the Warrant; and (iv) comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the Investor set forth in such Registration Statement; provided, however, that the Investor shall be responsible for the delivery of the Prospectus to the Persons to whom the Investor sells the Registrable Securities, and the Investor agrees to dispose of Registrable Securities in compliance with the plan of distribution described in the Registration Statement and otherwise in compliance with applicable federal and state securities or blue sky laws and regulations. 57

(b) If so requested by the Investor, or if the Investor determines to engage an underwriter (other than the Investor) in connection with the offering of any Registrable Securities (an "Underwritten Offering"), a managing underwriter or underwriters, the Company shall (i) promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriters, if any, and the Investor agrees should be included therein and (ii) make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after the Company has received notification of the matters to be incorporated in such prospectus supplement or post-effective amendment; provided, however, that the Company shall not be required to take any action pursuant to this Section 2.1(b)(ii) that would, in the opinion of counsel for the Company, violate applicable law. (c) In the event of an Underwritten Offering: (A) the Company shall enter into such reasonable agreements and take all such other reasonable actions in connection therewith (including those reasonably requested by the managing underwriters, if any) in order to expedite or facilitate the disposition of such Registrable Securities, and in such connection, the Company shall: (i) make such representations and warranties to the Investor and the underwriters with respect to the business of the Company (including with respect to businesses or assets acquired or to be acquired by the Company), and the Registration Statement, Prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance (subject to such exceptions as the Company may disclose) and scope as are customarily made by issuers to underwriters in underwritten offerings, and confirm such representations and warranties if and when requested; (ii) consent to indemnification provisions and procedures in the underwriting agreement no less favorable to the Investor and the underwriters than those set forth herein (or such other provisions and procedures acceptable to the Company, the Investor and the managing underwriters); and (iii) deliver such documents and certificates as may be reasonably requested by the Investor, its counsel and the managing underwriters, if any, to evidence the continued validity of their representations and warranties made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in the applicable underwriting agreement, this Agreement, the Purchase Agreement or the Warrant. (B) The Investor will enter into and perform its obligations under an underwriting agreement, in usual and customary form, including, without limitation, customary indemnification and contribution obligations, with the managing underwriter of such offering, and will take such other actions as are reasonably required in order to expedite or facilitate the disposition of the Registrable Securities, unless the Investor has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement; provided, however, that the Investor shall consult with the Company prior to any such Underwritten Offering and defer such offering for a reasonable period upon the commercially reasonable request of the Company. 58

(C) The Investor may not participate in any underwriting distribution hereunder unless it (i) agrees to sell its Registrable Securities on the basis provided in any underwriting agreements, (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting agreements and (iii) agrees to pay all underwriting discounts and commissions and other fees and expenses of investment bankers and any manager or managers of such underwriting, and legal expenses of the underwriter, applicable with respect to its Registrable Securities. (d) As early as practical prior to filing the Registration Statement or Prospectus, or any amendment or supplement thereto (excluding amendments deemed to result from the filing of documents incorporated by reference therein), the Company shall deliver to the Investor and to counsel representing the Investor, in accordance with the notice provisions of Section 4.8, copies of the Registration Statement and the Prospectus, together with exhibits thereto, which documents will be subject to review by the Investor and such counsel, and thereafter deliver to the Investor and such counsel, in accordance with the notice provisions of Section 4.8, such number of copies of the Registration Statement, each amendment and supplement thereto (in each case including all exhibits thereto), the Prospectus (including each preliminary prospectus) and such other documents or information as the Investor or counsel may reasonably request in order to facilitate the disposition of the Registrable Securities. (e) The Company shall deliver, in accordance with the notice provisions of Section 4.8, to the Investor such number of conformed copies of the Registration Statement and of each amendment and supplement thereto (in each case including all exhibits and documents incorporated by reference), such number of copies of the Prospectus (including each preliminary prospectus and any summary prospectus) and any other prospectus filed under Rule 424 promulgated under the Securities Act relating to the Investor's Registrable Securities, and such other documents, as such seller may reasonably request to facilitate the disposition of its Registrable Securities. (f) After the filing of the Registration Statement, the Company shall promptly notify the Investor of any stop order issued or threatened by the Commission in connection therewith and take all commercially reasonable actions required to prevent the entry of such stop order or to remove it if entered. (g) The Company shall use commercially reasonable efforts to (i) register or qualify the Registrable Securities under such other securities or blue sky laws and regulations of each jurisdiction in the United States as the Investor may reasonably (in light of its intended plan of distribution) request and (ii) cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities in the United States as may be necessary by virtue of the business and operations of the Company and do any and all other customary acts and things that may be reasonably necessary or advisable to enable the Investor to consummate the disposition of the Registrable Securities; provided, however, that the Company will not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 2.1(g), subject itself to taxation in any such jurisdiction, consent or subject itself to general service of process in any such jurisdiction, change any existing business practices, benefit plans or outstanding securities or amend or otherwise modify the Charter or Bylaws. 59

(h) In the event of an Underwritten Offering, the Company shall enter into customary agreements and take such other actions as are reasonably required in order to expedite the disposition of such Registrable Securities. (i) The Company shall make available to the Investor (and will deliver to Investor's counsel), (A) subject to restrictions imposed by the United States federal government or any agency or instrumentality thereof, copies of all public correspondence between the Commission and the Company concerning the Registration Statement and will also make available for inspection by the Investor and any attorney, accountant or other professional retained by the Investor (collectively, the "Inspectors"), (B) upon reasonable advance notice during normal business hours all financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records") as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company's officers and employees to supply all information reasonably requested by any Inspectors in connection with the Registration Statement; provided, however, that any such Inspectors must agree in writing for the benefit of the Company not to use or disclose any such Records except as provided in this Section 2.1(i). Any and all Records that the Company determines, in good faith, to be confidential and that it notifies the Inspectors are confidential shall be treated as confidential and not be disclosed by the Inspectors unless the disclosure or release of such Records is requested or required pursuant to oral questions, interrogatories, requests for information or documents or a subpoena or other order from a court of competent jurisdiction or other judicial or governmental process; provided, however, that prior to any disclosure or release pursuant to the immediately preceding clause, the Inspectors shall provide the Company with prompt notice of any such request or requirement so that the Company may seek an appropriate protective order or waive such Inspectors' obligation not to disclose such Records; and, provided, further, that if failing the entry of a protective order or the waiver by the Company permitting the disclosure or release of such Records, the Inspectors, upon advice of counsel, are compelled to disclose such Records, the Inspectors may disclose that portion of the Records that counsel has advised the Inspectors that the Inspectors are compelled to disclose; provided, however, that upon any such required disclosure, such Inspector shall use his or her best efforts to obtain reasonable assurances that confidential treatment will be afforded such information. The Investor agrees that information obtained by it solely as a result of such inspections (not including any information obtained from a third party who, insofar as is known to the Investor after reasonable inquiry, is not prohibited from providing such information by a contractual, legal or fiduciary obligation to the Company) shall be deemed confidential and shall not be used for any purposes other than as indicated above or by it as the basis for any market transactions in the securities of the Company or its affiliates unless and until such information is made generally available to the public. The Investor further agrees that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at its expense but with the assistance of the relevant Inspectors, to undertake appropriate action to prevent disclosure of the Records deemed confidential. (j) In the event of an Underwritten Offering of the resale of Registrable Securities pursuant to the Registration Statement, then to the extent required by the managing underwriters and reasonably necessary to effect a sale of Registrable Securities in accordance with prevailing business practices at the time of any such underwritten sale of Registrable Securities pursuant to a Registration Statement, the Company shall deliver to the Investor a signed counterpart, addressed to the Investor, of (1) an opinion or opinions of counsel to the Company and (2) a comfort letter or comfort letters from the Company's independent public accountants, each in customary form and covering such matters of the type customarily covered by opinions or comfort letters, as the case may be, as the Investor therefor reasonably requests. 60

(k) The Company shall otherwise comply with all applicable rules and regulations of the Commission, including, without limitation, compliance with applicable reporting requirements under the Exchange Act. (l) The Company shall appoint a transfer agent and registrar for all of the Registrable Securities covered by such Registration Statement not later than the effective date of such Registration Statement. (m) The Investor shall cooperate with the Company, as reasonably requested by the Company, in connection with the preparation and filing of any Registration Statement hereunder. The Company may require the Investor to promptly furnish in writing to the Company such information as may be required in connection with such registration including, without limitation, all such information as may be requested by the Commission or the NASD or any state securities commission and all such information regarding the Investor, the Registrable Securities held by the Investor and the intended method of disposition of the Registrable Securities. The Investor agrees to provide such information requested in connection with such registration within five (5) business days after receiving such written request and the Company shall not be responsible for any delays in obtaining or maintaining the effectiveness of the Registration Statement caused by the Investor's failure to timely provide such information. (n) Upon receipt of a Blackout Notice from the Company, the Investor shall immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until (i) the Company advises the Investor that the Blackout Period has terminated and (ii) the Investor receives copies of a supplemented or amended prospectus, if necessary. If so directed by the Company, the Investor will deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies in the Investor's possession (other than a limited number of file copies) of the prospectus covering such Registrable Securities that is current at the time of receipt of such notice. (o) If the Investor determines to engage in an Underwritten Offering, the Investor will enter into and perform its obligations under an underwriting agreement, in usual and customary form, including, without limitation, customary indemnification and contribution obligations, with the managing underwriter of such offering, and will take such other actions as are reasonably required in order to expedite or facilitate the disposition of the Registrable Securities. The Investor shall consult with the Company prior to any Underwritten Offering and shall defer such Underwritten Offering for a reasonable period upon the commercially reasonable request of the Company. (o) The Investor shall not take any action with respect to any distribution deemed to be made pursuant to the Registration Statement, which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law. 61

     DISCOVERY LABORATORIES SECURES $75 MILLION COMMITTED EQUITY FINANCING
                                    FACILITY

   Management will discuss additional details during conference call on July
                    9th at 10:30 AM EDT - see details below

DOYLESTOWN,  PA -- JULY 8, 2004 -- DISCOVERY LABORATORIES,  INC. (NASDAQ: DSCO),
has entered into a Committed  Equity  Financing  Facility  Agreement (CEFF) with
Kingsbridge  Capital Limited in which Kingsbridge has committed to finance up to
$75  million of capital to support  Discovery's  future  growth.  The  Agreement
requires Kingsbridge to purchase  newly-issued shares of Discovery common stock.
Discovery will  ultimately  determine the exact timing,  amount and price of any
CEFF  financings,  subject  to  certain  conditions.  Kingsbridge  is a  private
investment group, which operates as a closed fund,  managing  substantial assets
for its principal.  The CEFF allows  Discovery to raise capital as required,  at
the  time,  price  and in  amounts  deemed  suitable  to the  Company,  during a
three-year  period once the  registration  statement is filed by  Discovery  and
declared effective by the Securities and Exchange Commission.

John G.  Cooper,  Executive  Vice  President  and  Chief  Financial  Officer  of
Discovery  commented,  "The CEFF gives us enormous flexibility to raise adequate
amounts of capital when needed. Our financing strategy, particularly in light of
current  market  conditions,  does not  include  an  immediate  requirement  for
additional  equity  capital.  With this  innovative  financing  structure now in
place,  we have an ability to finance  the  Company at times when we believe the
appropriate value is reflected in our stock price. Normally,  such value accrues
after the achievement of key milestones.  In addition, I feel this CEFF offers a
favorable  cost of capital,  with  discounts and  associated  expenses less than
those  seen  generally  in PIPEs or  secondary  offerings.  Discovery  can still
participate in traditional  financing  structures if we feel it is beneficial to
do so.  This  CEFF,  together  with  our  ability  to avail  ourselves  of other
traditional financing structures,  allows us to make financing decisions that we
believe will be in the best interest of Discovery and its shareholders.  The $75
million  available  from the CEFF,  coupled with our existing  cash balances and
amounts  available under credit  facilities  provides the Company with over $120
million of potential financial resources."

Adam  Gurney,  Managing  Director  of  Kingsbridge,  stated,  "We are excited by
Discovery's  Surfactant  Replacement  Therapy  pipeline,  which we believe is of
great  medical  potential.  Discovery  has  several  milestones  expected  to be
announced  in 2004  and 2005 - each  potentially  a  significant  value-creating
opportunity  for  healthcare,  Discovery and its investors.  Kingsbridge is very
pleased to be working with Discovery as it builds the first potential surfactant
product  pipeline for  respiratory  medicine and  executes its  transition  to a
commercial company with the potential FDA approval of Surfaxin(R) for RDS."

Certain details of the Committed Equity Financing facility are as follows:

o     For a period  of three  years,  Discovery  can  access  up to $75  million
      dollars  from   Kingsbridge  in  exchange  for   newly-issued   shares  of
      Discovery's  common stock.  Discovery may access the capital after the SEC
      declares  effective  the  registration  statement to be filed by Discovery
      covering the resale of the shares of common stock  issuable in  connection
      with the CEFF and the  shares  of  common  stock  underlying  the  warrant
      discussed below.

                                       68

o Capital may be accessed under the CEFF in tranches of up to $18.75 million, subject to certain conditions. Each tranche will be priced during the 15-day financing period with Discovery controlling the minimum acceptable purchase price for any shares to be issued to Kingsbridge during that time. Kingsbridge shall purchase shares of common stock pursuant to the CEFF at discounts ranging from 6% to 10% of the average market price of the common stock during the financing period, with the reduced discounts applying if the price of the common stock is equal to $9.01 or more. o Discovery is not obligated to utilize any of the $75 million available under the CEFF and there are no minimum commitment or minimum use penalties. The CEFF agreement does not contain any restrictions on Discovery's operating activities, automatic pricing resets or minimum market volume restrictions. o The agreement does not prohibit Discovery from conducting additional debt or equity financings, including PIPEs, shelf offerings, secondary offerings or any other fixed future-priced securities. o Throughout the term of the CEFF, Kingsbridge is restricted from engaging in any transaction intended to reduce its economic risk of owning shares of Discovery common stock including, without limitation, the purchase of any option or contract to sell, selling "short" or "short against the box", or otherwise entering into any other security transaction the purpose of which is to hedge its risk of ownership of the common stock. o In connection with the CEFF, Discovery issued a warrant to Kingsbridge to purchase up to 375,000 shares of common stock at an exercise price of $12.0744 per share. The exercise term of the warrant is five years beginning with the 6-month anniversary of the closing date of the agreement. The warrant must be exercised for cash, except in limited circumstances. Mr. Cooper continued, "Kingsbridge is a highly-respected investment group with an extensive network of contacts within the financial community. They have been a shareholder of Discovery for the past two years. The financial and legal terms of this financing structure is the product of substantial deal and market analysis by Discovery and Kingsbridge. Both parties feel that this process has resulted in a well thought out and innovative financing vehicle." Discovery will be hosting a conference call on Friday, July 9th at 10:30 AM EDT. Management will provide more details on the Committed Equity Financing Facility. The call in number is 800-665-0669.

The securities issuable in connection with the CEFF and upon the exercise of the warrant issued to Kingsbridge have not been registered under the Securities Act of 1933 and may not be offered or sold in the United States absent registration. Discovery has agreed to file, no later than August 23, 2004, a registration statement for the resale of the shares of common stock issuable in connection with the CEFF and the shares of common stock underlying the warrant. ABOUT DISCOVERY LABORATORIES Discovery Laboratories, Inc. is a biopharmaceutical company developing its proprietary surfactant technology as Surfactant Replacement Therapies for respiratory diseases.

Discovery believes that through its technology, pulmonary surfactants have the potential, for the first time, to be developed into a series of respiratory therapies for critical care and other hospitalized patients where there are few or no approved therapies available. Discovery has filed a New Drug Application with the FDA for clearance to market Surfaxin, the Company's lead product, for the prevention of Respiratory Distress Syndrome in premature infants. Discovery is currently conducting a Phase 2 clinical trial for Acute Respiratory Distress Syndrome in adults, Phase 3 and Phase 2 clinical trials for Meconium Aspiration Syndrome in full-term infants.
