Item 5. Other Events On March 7, 2002, Discovery Laboratories, Inc., a Delaware corporation ("Discovery"), issued a press release to announce that it had entered into a collaboration arrangement (the "Collaboration") effective as of March 6, 2002, with Laboratorios Del Dr. Esteve, S.A. ("Esteve"). This collaboration arrangement supersedes the existing sublicense and supply agreements between Discovery and Esteve and expands the territory covered by those original agreements to all of Europe, including the Russian Federation, and Central America and South America. In connection with this transaction, Discovery raised $4.5 million in gross proceeds and issued 821,862 shares of its common stock, par value $.001 per share ("Common Stock"). After payment of fees and associated expenses, Discovery intends to use the net proceeds of approximately $4.455 million, for working capital and general corporate purposes, including further development of Discovery's platform technology, based on humanized lung surfactants, in an effort to develop potential novel respiratory therapies, such as an aerosol spray for the treatment of asthma, and pulmonary drug delivery products with the potential to deliver other pharmaceutical products to the lungs. Transaction Overview In connection with the Collaboration, Discovery entered into a series of agreements with Esteve, which include a sublicense and collaboration agreement (the "Collaboration Agreement"), a supply agreement (the "Supply Agreement") and a common stock purchase agreement (the "Purchase Agreement"). As further discussed below and subject to the terms and conditions set forth in these agreements, Esteve agreed to provide certain commercialization services throughout Europe, Central America and South America for Discovery's lead product candidate, Surfaxin(R), for the treatment of idiopathic respiratory distress syndrome in premature infants ("IRDS"), meconium aspiration syndrome in full-term infants ("MAS"), acute respiratory distress syndrome in adult patients ("ARDS") and acute lung injury in adult patients ("ALI", ARDS and ALI are sometimes referred to herein collectively as "ALI/ARDS"). Discovery and Esteve have agreed to an exclusive supply agreement which provides that Esteve will purchase all of its Surfaxin drug product requirements from Discovery at an established transfer price based on sales of Surfaxin by Esteve and/or its sublicensee(s). Esteve has also agreed to sponsor certain clinical trial costs related to obtaining European Agency for Medicinal Products (EMEA) approval for commercialization of Surfaxin in Europe for the ALI/ARDS indications. In addition to a $4.0 million equity investment in Discovery, Esteve also agreed to pay to Discovery an up-front license fee of $500,000 and to make certain milestone payments to Discovery upon the attainment of certain corporate milestones that are discussed in greater detail below. 2

Collaboration Arrangements Pursuant to the Collaboration Agreement, Esteve will provide commercialization services for the promotion of Surfaxin for IRDS, MAS and ALI/ARDS throughout Europe, including the Russian Federation, Central America and South America and will pay for certain clinical trial costs. The commercialization services to be provided by Esteve will include customary pre-launch, launch and post-launch marketing activities including retaining marketing and sales personnel for commercialization of Surfaxin in the aforementioned territory. Under the Supply Agreement, Discovery will manufacture Surfaxin for distribution and sale by Esteve in the territory covered by the Collaboration. Subject to the approval of Discovery and certain limitations and requirements set forth in the Collaboration Agreement, Esteve may sublicense its commercialization rights to third parties. Esteve has agreed to pay certain clinical trial costs related to obtaining EMEA approval for commercialization of Surfaxin for the ALI/ARDS indications. In general, Discovery will be responsible for regulatory activities relating to Surfaxin, including with respect to EMEA filings, however, Esteve will be responsible for regulatory activities relating to specific countries in the territory covered by the Collaboration. Moreover, subject to prior termination of this right as provided in the Collaboration Agreement, Esteve has been granted a right of first negotiation until March 6, 2009, regarding possible collaborative licenses or other suitable arrangements that would provide for the clinical development and marketing of other products that may be developed by Discovery, whether related to Surfaxin or otherwise, in the territory covered by the Collaboration. In addition, the Collaboration Agreement specifies that any such future collaborative agreements would provide for suitable up-front cash payments and cash milestones and shared responsibility for clinical development work and expenses related to the new technology. Further, Esteve would be responsible for customary commercialization activities and costs and Discovery would supply any such future products. In addition to the monies received by Discovery in connection with Esteve's equity investment in Discovery and payment of the up-front license fee discussed in greater detail below, upon receipt of EMEA marketing regulatory approval of Surfaxin for sale in Europe for each of the IRDS and MAS indications and the first to be approved of the ARDS or ALI indications, Esteve has agreed to make certain cash milestone payments to Discovery. The management of the overall strategic relationship between Esteve and Discovery and marketing and sales activities of Collaboration will be managed and governed by a joint steering committee (the "Joint Steering Committee") which will be comprised of representatives appointed by Esteve and Discovery. In addition, a separate joint development committee (the "Joint Development Committee") will be formed to oversee development of Surfaxin in the territory covered by the Collaboration. The Joint Development Committee will be comprised of four members consisting of two executives to be appointed by each of Discovery and Esteve. Each committee will be chaired alternately by a representative of Discovery and Esteve with each such chairperson serving for a one-year period. Equity Investment and Licensing Fee Pursuant to the Purchase Agreement, Esteve purchased 821,862 shares of Common Stock at a price of $4.867 per share, representing a total equity investment of $4 million. In 3

addition, Esteve paid to Discovery an up-front licensing fee of $500,000. Under the Purchase Agreement, Esteve has agreed to certain limitations on its trading of, and purchase of additional shares of, Common Stock, as well as certain prescriptions regarding the voting of its shares. The shares of Common Stock purchased by Esteve have not been registered under the Securities Act of 1933 (the "1933 Act") and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the 1933 Act. In addition, all such shares of Common Stock are subject to certain restrictions on transfer as set forth in the Purchase Agreement. Esteve will have up to two "demand" registration rights that require Discovery to register shares of Common Stock held by Esteve for resale under the 1933 Act. In addition, subject to certain limitations, Esteve has customary "piggyback" rights to include such shares of Common Stock in other registrations of securities filed by Discovery for resale under the 1933 Act.

At Licensee's request, Licensor shall provide Licensee with any additional information solely to the extent that such additional information is reasonably necessary for Licensee to evaluate its possible interest in the New Product. (b) Within sixty (60) days from the date of any such New Product Presentation, Licensee shall notify Licensor in writing of Licensee's intention to enter into negotiations to license the rights to any such product. Licensee and Licensor hereby expressly agree that such license or any other similar grant of rights in respect thereto shall contain, among other customary terms and conditions, the following: (i) up-front cash payment(s) to be paid by Licensee to Licensor in o amounts that are consistent with customary pharmaceutical industry practices and appropriate with reference to the technology value and potential product value of such New Product; 7

(ii) Licensor, Licensee and other sublicensees of the Licensor shall share all future clinical development work and or expenses with respect to any such New Product opportunity, in relation with Phase 3 clinical trials necessary to obtain and/or maintain the Marketing Regulatory Approvals in the Licensed Territory, on a proportional basis using the relevant IMS annual global pharmaceutical data relative to the aggregate pharmaceutical market size of the proposed licensed territory for all pharmaceutical products as the basis of determining the amount of such costs to be borne by each of the parties at the time. Licensee and its sublicensees shall be responsible for the work and costs associated with any and all clinical development activities that is conducted in the Licensed Territory for the New Product that are not necessary to obtain or maintain Marketing Regulatory Approval for any such New Product; (iii) payment to Licensor of cash milestones in amounts that are consistent with customary pharmaceutical industry practices and are reflective of the value of such New Product created during the development process and which amounts take into account Licensee's contribution to development of any such value; (iv) Licensee shall be responsible for customary commercialization costs associated with the New Product including, without limitation, sales, marketing, distribution, and safety and medical affairs expenses, in a manner similar to that set forth in this Agreement with respect to Licensed Products; and (v) Licensor shall be responsible for the manufacture of any such New Product. The supply price for the New Product, which shall duly take into account the development expenses and cash milestones paid by Licensee for any such New Product, shall ensure a reasonable profit for Licensee in the light of the prevailing and expected market conditions at that time. (c) Should Licensee fail to exercise its option to negotiate in accordance with this Section, or should the parties fail to enter into definitive agreements within hundred and twenty (120) days of the date of Licensee's notice, delivered to Licensor in accordance with Section 2.5(b), Licensor shall have the right to offer the New Product opportunity to any other third party offeree(s) at terms and conditions that are in substance no more favorable for such other third party offeree(s) than those last offered to Licensee in writing , provided, however, that Licensor shall not execute any agreement on the New Product with any such third party offeree(s) without previously offering Licensee the right to enter into an agreement on substantially similar terms than those contained in the final agreement with the relevant third party offeree. (d) Should senior executive officers of Licensor become aware of the possible interest of any third party to enter into an agreement in relation with any New Product prior to completion of all Phase 2 clinical trials, then Licensor shall promptly notify 8

Licensee of such possible interest of a third party. In such event, and notwithstanding Section 2.5(a) hereinabove, Licensor and Licensee agree to initiate good faith negotiations with respect of such New Product with a view to enter into an agreement for the development and commercialization of such New Product prior to the completion of the Phase 2 development for that New Product; provided, however, that in any such event the parties agree that any negotiations hereunder shall be performed within timeframes similar to those as set forth in Section 2.5 and shall encompass terms and conditions similar to those set forth in Sections 2.5(b) and (c). Section 2.6. Product Failure. In the case of a Product Failure, the Steering Committee shall seek to identify a single Replacement Product for development by Licensee and Licensor for such Product Failure. In the event a Replacement Product has not been identified for development in writing by the Steering Committee within six (6) months of such Product Failure, or within such other time-limit that may be agreed by the Chief Executive Officers (or equivalent position) of Licensor and Licensee, either party shall have, within thirty (30) days following expiration of such period by written notice to the other party, the right to terminate this Agreement with respect to such Major Indication in those countries where the Product Failure has occurred. The Steering Committee shall prepare a written development plan with respect to each Replacement Product that has been identified for development by the Steering Committee as promptly as practicable following its identification, which shall include provisions for the funding of development with respect to such Replacement Product by Licensor, Licensee and other Licensor's licensees in countries outside the Licensed Territory where Licensor or its licensees intend to commercialize such Replacement Product. In the event the Steering Committee has not reached agreement upon such development plan, including the funding of development in connection with the Replacement Product, within ninety (90) days after identification of a Replacement Product for development hereunder, then either party shall have the right to terminate this Agreement with respect to such Major Indication in those countries where a Marketing Regulatory Approval for such Major Indication has not been obtained, by written notice to the other within the thirty (30) days following expiration of such ninety (90) day period; provided, however, that in such event, Licensor shall not enter into any agreement relating to the development, distribution, marketing and sale of the same product in the Licensed Territory with a third party on terms which, taken as a whole, are more favorable to such third party than those last offered to Licensee in writing by Licensor for such product. For the avoidance of doubt, this Section 2.6 shall not limit in any respect whatsoever Licensee's rights under Section 2.5 and under Section 7.3. 9

ARTICLE 3 GRANT BACK In consideration for Licensor (i) making the Licensed Know-how (including any improvements thereto and solely to the extent provided for in Section 2.1) available to Licensee on a continuing basis for the duration of this Agreement and (ii) procuring, and making available to Licensee the benefit of, equivalent grants from Licensor's other licensees for the Licensed Products outside the Licensed Territory, Licensee hereby grants to Licensor and such other licensees as Licensor may designate a royalty-free, nonexclusive license outside the Licensed Territory and limited to the Field, with the right to grant sublicenses, under any and all inventions and Licensee Proprietary Information (whether patentable or not) hereafter during the term of this Agreement, developed, possessed or acquired by Licensee related to the Licensed Products, Patent Rights, Licensed Know-how or Licensed Methods; provided that Licensee is not legally restricted or prevented from granting such rights in connection with the relevant invention. Licensee shall provide Licensor with a written enabling disclosure of each invention (such as a patent application or internal docket reference) unambiguously identifying it as an invention governed by this Article 3 prior to filing a patent application or taking any other action disclosing or potentially disclosing the same to third parties. Licensee shall promptly disclose all Licensee Proprietary Information to Licensor and, subject to the execution of confidentiality undertakings comparable to those set forth in Article 6, to Licensor's other licensees (and or Affiliates and permitted sublicensees) of Patent Rights outside the Licensed Territory on a continuing basis during the term of this Agreement. Licensee hereby grants to Licensor and such licensees a royalty-free nonexclusive license, with the right to grant sublicenses, to use the Licensee Proprietary Information outside the Licensed Territory and limited to the Field.

"First Commercial Sale" shall mean the first commercial sale by Buyer, its Affiliates or sublicensees of any Licensed Product following final EMEA or other regulatory approval required to market such Licensed Product commercially in the Licensed Territory for use in humans. "Specifications" shall mean the Licensed Product specifications contained in the registration dossier of the Licensed Product as approved by the EMEA and the other regulatory authorities having jurisdiction in the Licensed Territory, as the same may be amended from time to time in accordance with applicable regulatory procedures. "Transfer Price" shall mean the price for each Licensed Product established in accordance with the pricing system as set forth in Section 2.2. "Unrelated Third Parties" shall mean Persons other than Buyer and Seller and Affiliates and sublicensees of Buyer and Seller or any other related Persons and shall include hospital formularies and other similar critical and therapeutic care providers who typically purchase and administer products and therapies such as the Licensed Products. ARTICLE II PURCHASE AND SALE OF PRODUCTS Section 2.1. Purchase and Sale; Delivery; Acceptance or Rejection. (a) Seller agrees to sell to Buyer such quantities of Licensed Products, manufactured in conformity with cGMP and meeting the Specifications, as Buyer may order in accordance with the terms and conditions of this Agreement. Subject to the provisions of Section 7.2 hereof, so long as this Agreement shall remain in effect, Buyer agrees, for itself and its Affiliates and sublicensees, to satisfy solely through the purchase of Licensed Products from Seller under this Agreement one hundred percent (100%) of Buyer's and its Affiliates' and sublicensees' requirements for Licensed Products. (b) Purchase orders issued by Buyer to Seller with respect to purchases of Licensed Products shall be subject to, and governed exclusively by, the terms of this Agreement. Buyer agrees not to issue to Seller any purchase order containing terms different from those set forth herein and further agrees that no shipment of Licensed Product by Seller in accordance with a nonconforming purchase order shall be deemed to be acceptance of any terms of such purchase order conflicting with the terms of this Agreement except to the extent such conflicting terms are initialed by Seller with the words "change 2

accepted" written thereon by Seller. Except as aforesaid, this Agreement shall override all other conflicting terms of purchase and/or sale contained in any purchase and/or sale document generated by Seller or Buyer. (c) Subject to paragraph (d) below, all Licensed Product sold to Buyer hereunder shall be delivered FCA Seller's Facility or distribution warehouse (Incoterms 2000).

(e) Buyer may reject any portion of any shipment of Licensed Product which does not conform with the Specifications. In order to reject a shipment, Buyer must (i) give notice to Seller of Buyer's intent to reject the shipment within thirty (30) days of receipt together with a detailed written indication of the reasons for such possible rejection, and (ii) as promptly as reasonably possible thereafter, but in any event within an additional thirty (30) days, provide Seller with notice of final rejection and the full basis therefor. After notice of intent to reject is given, Buyer shall cooperate with Seller in determining whether rejection is necessary or justified. If such notices of intent to reject and final rejection are not timely received, Buyer shall be deemed to have accepted such delivery of Licensed Product and to have waived all claims for non-conformity with the Specifications, damage, defect or shortage, other than claims for latent defects not capable of discovery by Buyer upon physical examination. In the event of latent defects not capable of discovery by Buyer upon physical examination, Buyer shall inform Seller within fifteen (15) days of discovering any such defect. Buyer shall be entitled to a refund of the purchase price (together with insurance, freight charges and, where applicable, custom duties) of properly rejected Licensed Products at the time they are ultimately rejected, provided that if Seller disputes the rejection, refund shall be made, if at all, at the time the dispute is finally resolved. Seller shall notify Buyer as promptly as reasonably possible (but in any event no later than thirty (30) days after receipt of Buyer's 3

final rejection notice) whether it accepts Buyer's basis for any rejection. In the event Seller disputes Buyer's rejection, the parties will select a mutually agreeable independent third party laboratory which shall determine whether the rejected Licensed Products meet the applicable Specifications and shall confirm or dissent from Buyer's rejection of Licensed Products. If the parties are unable to agree on a laboratory firm within thirty (30) days after receipt of Buyer's final rejection notice, the laboratory shall be appointed by computer generation of a random number, with an even number signifying Seller's right to designate the laboratory and an odd number designating Buyer's right to designate the laboratory. If the independent tester confirms Buyer's rejection, Seller will pay the fees of the tester, and if the tester dissents from Buyer's rejection, Buyer will pay the fees. (f) Whether or not Seller accepts Buyer's basis for rejection, promptly on receipt of a notice of rejection, Seller shall use its commercially reasonable efforts, at Buyer's request, to provide replacement Licensed Product, which shall be purchased by Buyer as provided in this Agreement as soon as reasonably practicable. (g) Unless Seller requests the return to it of a rejected batch within sixty (60) days of receipt of Buyer's final notice of rejection, Buyer shall, at Seller's cost, destroy such batch promptly and provide Seller with certification of such destruction. Buyer shall, upon receipt of Seller's request for return, promptly dispatch said batch to Seller, at Seller's cost. (h) No change to the Specifications shall be effective unless the same shall be required or permitted by any regulatory agency having jurisdiction over (i) any country in the Licensed Territory, (ii) Buyer or (iii) the Licensed Products (and if not required, shall be agreed to in writing by Buyer and Seller). Seller shall give Buyer advance notice of any change to the Specifications required by a regulatory agency. 2.2 Transfer Price; Method of Payment. (a) Buyer shall purchase Licensed Products from Seller hereunder at the applicable Transfer Price. The Transfer Price for each unit of Licensed Product shall equal [***] of the Base Integrated Price (as such term is hereinafter defined) for any such Licensed Product in the Licensed Territory, subject to paragraph (d) below. The "Base Integrated Price" shall mean, with respect to each unit of Licensed Product purchased by Licensee, that price that is determined prior to the first commercial sale of any such Licensed Product in any country of the Licensed Territory by mutual agreement between Buyer and Seller in their best good faith efforts (and as such price may be amended from time to time by mutual agreement of the parties); provided, however, that should the parties fail to agree on any such price prior to the first commercial sale of any such Licensed Product in the Licensed Territory such price shall equal the gross amount invoiced to Unrelated Third Parties for such Licensed Product in the Licensed Territory, less: (i) trade and reasonable and customary cash - ---------- Information marked by [***] has been omitted pursuant to a request for confidential treatment. The omitted portion has been separately filed with the Securities and Exchange Commission. 4

discounts allowed; (ii) refunds, rebates, chargebacks, retroactive price adjustments and any other allowances which effectively reduce the net selling price; (iii) returns, credits and allowances and (iv) sales taxes paid or absorbed by Buyer in respect of such sales. Except as set forth in subsections (i)-(iv) in the immediately preceding sentence, no deductions or offsets shall be made against any such gross amount invoiced including, without limitation, on account of any commissions paid to employees of Buyer, its Affiliates or sublicensees, cost of collections, bad debts or sales, marketing and promotional expenses of any kind. Such amounts shall be determined from books and records maintained in accordance with generally accepted accounting principles applied in each country of the Licensed Territory, consistently applied. (b) Seller shall invoice Buyer for each shipment of Licensed Products delivered by Seller to Buyer, its Affiliates or sublicensees at the Transfer Price converted into U.S. Dollars at the exchange rate of the last Business Day of the calendar month immediately preceding the month when the Licensed Product is shipped to Buyer, as quoted by the Wall Street Journal. (c) Buyer shall pay Seller's invoices in U.S. Dollars not later than ninety (90) days following the date of the applicable invoice by wire transfer to the bank account designated by Seller. (d) For the avoidance of doubt, the parties hereby acknowledge and agree that the Base Integrated Transfer Price for Licensed Products shall be determined by the parties in good faith and shall be based upon a mutually agreeable pricing schedule for such Licensed Products that is intended to ensure that both Buyer and Seller achieve reasonable profits with respect to sales thereof. (e) All payments under this Section 2.2 shall be free of all withholdings of any nature whatsoever (including, without limitation, withholding taxes, monetary transfer fees, or similar taxes and charges), and in the event any withholding is required, Buyer shall pay the same together with such additional amount as is required so that each such payment shall be, under any circumstances and in any event, in the amount as set forth or referred to herein. ARTICLE III PRODUCTION OF PRODUCTS Section 3.1. Manufacturing of Licensed Products. (a) Until such time, if any, as a Seller-owned manufacturing facility (an "Owned Facility") is qualified for the manufacture of Licensed Products sold to Buyer hereunder, Seller shall manufacture or have manufactured the Licensed Products sold to Buyer hereunder at a contract manufacturing facility 5

(a "Contract Facility") selected by Seller and reasonably acceptable to Buyer. Commencing sixty (60) days prior to the First Commercial Sale of any Licensed Product in a country of the Licensed Territory (provided that such date of First Commercial Sale has been communicated to Seller at least one hundred and eighty (180) days in advance) Seller shall maintain at least one alternate production site for Licensed Products sold to Buyer hereunder, which alternate production site, if a Contract Facility, shall also be selected by Seller and reasonably acceptable to Buyer. Seller's obligation to maintain an alternate manufacturing facility may also be satisfied through a sublicensing arrangement complying with Section 3.2. (b) Seller shall be responsible for obtaining and maintaining all necessary licenses, registrations, authorizations and approvals (other than such licenses, registrations, authorizations and approvals that are required to be obtained or made by an owner or operator of a Contract Facility) which are necessary to manufacture, handle, store, label, package, transport and ship Licensed Products under cGMP conditions and in accordance with other regulatory requirements. (c) Seller shall provide Buyer with copies of any correspondence sent from Seller to governmental entities relating to the manufacturing, handling, storage, labeling, packaging, transportation or shipment of Licensed Products at the time such correspondence is sent by Seller, purged of Seller proprietary and/or confidential information and trade secrets. Seller shall provide Buyer with copies of any comments, responses, notices or other correspondence received by Seller from any governmental entity relating to the foregoing matters within five (5) Business Days of receipt of such correspondence by Seller, purged of any Seller proprietary information and/or trade secrets. (d) Seller shall furnish to Buyer (i) a summary of any report or correspondence issued by a governmental entity (or a third party authorized by a governmental entity) in connection with a visit or inquiry relating to any Owned Facility or, to the extent Seller is provided with such information, any Contract Facility, including but not limited to, any FDA Form 483 or warning letter and (ii) not later than ten (10) Business Days after the time Seller provides such to a governmental entity, summaries of any and all proposed responses or explanations relating thereto, in each case purged of trade secrets or other confidential or proprietary information of Seller. After the filing of a response with the appropriate governmental entity, Seller will notify Buyer of any further oral and/or written contacts with a governmental entity (or a third party authorized by a governmental entity) relating to the manufacturing, handling, storage, labeling, packaging, transportation or shipment of Licensed Products. (e) If requested in writing by Buyer, Seller shall permit Buyer to inspect, once per year, during normal business hours, Seller's Facilities and 6

manufacturing records to the extent Buyer deems it reasonably necessary to enable Buyer to verify compliance with any statutory or regulatory requirements to which Buyer is subject and which are applicable to the manufacture and/or packaging of Licensed Products. Notwithstanding the foregoing, Buyer shall have the right to inspect Seller's Facilities and manufacturing records at any time, in the event that there is a quality or regulatory problem with any Licensed Product. If, as a result of any such inspection, Buyer reasonably and in good faith concludes that Seller is not in compliance with any regulatory obligations or requirements applicable to Buyer, Buyer shall so notify Seller in writing, specifying such areas of noncompliance in reasonable detail and Seller shall remedy the problems identified. (f) Seller agrees to use all reasonable efforts to promptly rectify or resolve any deficiencies noted by a governmental entity (or third party authorized by a governmental entity) in a report or correspondence issued to Seller with respect to an Owned Facility or a Contract Facility. Section 3.2. Subcontracting. It is understood and agreed that Seller shall have the right in connection with its performance hereunder to contract with such third parties as Seller deems advisable to manufacture Licensed Products, provided that (i) manufacture and/or quality control by any such third party has been authorized by the competent regulatory authorities in the Licensed Territory, (ii) Seller shall provide Buyer with not less than fifteen (15) Business Days' advance notice of its intent to contract with any third party and shall identify such third party to Buyer, (iii) Buyer may audit Seller's contractor's qualifications and (iv) Seller shall remain fully liable for its performance hereunder to the same extent as if such contractor had not been engaged. Section 3.3. Exclusivity. On a country-by country basis, for so long as the Collaboration Agreement remains in effect with respect to any such country in the Licensed Territory, until such time as Buyer has a fully paid-up license in such country in accordance with the terms of the Collaboration Agreement, Seller shall supply Licensed Products only to Buyer for distribution within such country. Section 3.4. Allocation of Supplied Licensed Products In the event of shortage or inability to timely supply the required Licensed Product, Licensor undertakes and agrees that the amounts of Licensed Products available shall be allocated on an equitable basis according to forecasts received and that Licensee shall not be treated less favorably than Licensor, its Affiliates and other distributors and/or sublicensees. 7

ARTICLE IV QUANTITY FORECASTS; ORDERS Section 4.1. Forecasts. (a) In order to assist Seller in planning its production, commencing sixty (60) days prior to the calendar month in which the First Commercial Sale of Licensed Products takes place in any country in the Licensed Territory, Buyer shall provide Seller with a twelve (12) month rolling forecast of the quantities of such Licensed Product required by Buyer, by month, for the following twelve (12) months. The first three (3) months of such projections shall constitute a binding commitment to order the quantity of such Licensed Product forecast for such period, provided that with respect to the first twelve (12) months following such First Commercial Sale of Licensed Products in any country in the Licensed Territory, only the first month's forecast with respect to such country shall be binding provided that the portion of such forecast relating to such country is separately stated and is so indicated. Projections for months four (4) through twelve (12) (or, as provided above with respect to product launches in the Licensed Territory, months two (2) through twelve (12)) shall be made in good faith and shall constitute Buyer's best estimates of future orders, but shall not be binding on Buyer. Updated twelve (12) month forecasts will be provided at the beginning of each succeeding calendar month for the twelve (12) month period commencing sixty (60) days thereafter. Buyer's forecast shall also describe anticipated regulatory modifications to any English language version of Licensed Product labeling proposed by Seller. Seller shall, no later than fifteen (15) Business Days after receipt of each such forecast, notify Buyer in writing of any prospective problems of which Seller is aware of that might prevent Seller from meeting Buyer's forecast order quantities or estimated delivery dates. (b) Notwithstanding Buyer's obligation to provide forecasts as set forth in Section 4.1(a), Buyer hereby agrees that it shall provide Seller with its firm purchase orders for Licensed Product in accordance with the lead-times and batch size increments to be specified by Seller in writing as soon as reasonably practicable but in any event before Buyer places its first order for Licensed Products, such lead-times and batch sizes to be applicable during the term of this Agreement unless otherwise agreed in writing by the parties; provided, however, that Buyer shall have the right, up to the date of manufacture, to issue binding change orders to increase or decrease such purchase orders with the consent of Seller, which shall not be unreasonably withheld so long as Buyer agrees to compensate Seller for any damages suffered by Seller as a consequence of such change order (including damages attributable to loss of allocable overhead recoupment, but excluding loss of profit), provided that Seller shall advise Buyer before carrying out any change order of Seller's estimated increased cost of doing so. Buyer agrees to accept partial shipments of Licensed Products should, for any reason, it become necessary to ship in advance of order completion, provided that 8

Seller shall (i) give advance written notice to Buyer of such shipment and (ii) bear any additional cost to Buyer of receiving Licensed Products in partial shipments. Seller shall make all commercially reasonable efforts to comply with any revisions to purchase order requirements consistent with the provisions of Section 4.1(a) and this Section 4.1(b). Seller, within ten (10) Business Days after the date that a purchase order is issued to it, shall acknowledge receipt of Buyer's order and confirm in writing that the order can be supplied. For purposes hereof, a purchase order will be deemed issued on the earlier of (i) the date that Seller receives the purchase order via mail and (ii) the date of receipt of the telecopied purchase order. Section 4.2. Purchase Order Contents. (a) Each purchase order shall specify the quantity, concentration and container size of Licensed Product ordered within the Specifications, and the required delivery schedule. Seller shall use reasonable commercial efforts to deliver each shipment of Licensed Product within five (5) days of the delivery dates specified in the delivery schedule set forth in Buyer's purchase order relating thereto (provided that in no event shall any such delivery dates be less than the lead time established pursuant to Section 4.1(b), unless otherwise consented to by Seller) using carriers mutually agreeable to Buyer and Seller. Seller shall use commercially reasonable efforts to accommodate "Rush" orders from Buyer. (b) When all appropriate validation and quality control release criteria for a particular shipment of Licensed Product have been met (the "Release Date"), Seller shall notify Buyer in writing of the expected delivery dates (including details of destination, date and time) to enable delivery and receipt to be coordinated. Title and risk of loss to Licensed Products shall pass to Buyer upon delivery of Licensed Products by Seller to the carrier. Section 4.3. Packaging.

Section 6.3. Retention of Samples. Seller shall retain as samples such quantities of Licensed Products from each batch of Licensed Product as Buyer shall reasonably request. Retained samples shall be maintained in a suitable storage facility for one (1) year past the product's expiration date.

Section 6.4. Recalls. Buyer shall notify Seller promptly if any Licensed Product is the subject of a recall, market withdrawal or correction within the Licensed Territory (a "Recall"), and Buyer and/or its designee shall have sole responsibility for the handling and disposition of such Recall. Buyer and/or its designee shall bear the costs of all Recalls of Licensed Products except to the extent that such Recall shall have been the result of Seller's breach of any of the warranties set forth in this Agreement and/or the Collaboration Agreement, in which case Seller will promptly reimburse Buyer to such extent for actual, direct costs sustained as a result of the Recall. In the event that Seller disputes Buyer's determination that the fault is due to Seller and/or to its agent, the Parties will select a mutually agreeable outside consulting firm which will be instructed to review the applicable information and data and to confirm or dissent from Buyer's determination. If the consulting firm confirms Buyer's determination, Seller will pay the fees of such consulting firm. Buyer and/or its designee shall maintain records of all sales of Licensed Products and customers sufficient to adequately administer a Recall, market withdrawal or correction for a period of three (3) years after termination or expiration of this Agreement. Except as required by law, Buyer and/or its designee shall serve as the sole point of contact with the applicable governmental entity concerning any Recall within the Licensed Territory with respect to Licensed Products and Seller shall serve as the sole point of contact with the FDA with respect to any Recall.

Representations and Warranties by, and Covenants of, the Purchaser. The Purchaser represents and warrants to, and covenants and agrees with, the Company, as of the Closing Date, as follows: 5.1 Authorization. Purchaser is duly organized and in good standing in the jurisdiction of its organization and has all requisite legal and corporate or other power and capacity and has taken all requisite corporate or other action to execute and deliver the Agreement, to purchase the Shares to be purchased by it and to carry out and perform all of its obligations under the Agreement. This Agreement has been duly authorized, executed and delivered and constitutes the legal, valid and binding obligation of Purchaser, enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium, reorganization or other similar laws affecting the enforcement of creditors' rights generally and as to limitations on the enforcement of the remedy of specific performance and other equitable remedies. If Purchaser is an entity, the person(s) signing on behalf of such entity hereby warrant and represent that they have the authority to execute this Agreement on behalf of each party for whom they have signed. 5.2 Investor Status. Purchaser is an "Accredited Investor" as defined in Rule 501 of Regulation D promulgated under the Securities Act. Purchaser acknowledges receiving and reviewing the documents comprising the SEC Reports, including the documents filed with the SEC included as exhibits thereto. Purchaser is aware of the Company's business affairs and financial condition and has had access to and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser has such business and financial experience as is required to give it the capacity to utilize the 6

information received, to evaluate the risks involved in purchasing the Shares, to make an informed decision about purchasing the Shares and to protect its own interests in connection with the purchase of the Shares and is able to bear the risks of an investment in the Shares. Purchaser is not itself a "broker" or a "dealer" as defined in the Exchange Act and is not an "affiliate" of the Company as defined in Rule 405 promulgated under the Securities Act. 5.3 Investment Intent. Purchaser is purchasing the Shares for its own account as principal, for investment purposes only and not with a present view to or for resale, distribution or fractionalization thereof, in whole or in part, within the meaning of the Securities Act. Purchaser understands that its acquisition of the Shares has not been registered under the Securities Act or registered or qualified under any state securities or "blue sky" laws in reliance on specific exemptions therefrom, which exemptions may depend upon, among other things, the bona fide nature of Purchaser's investment intent as expressed herein. Purchaser has, in connection with its decision to purchase the number of Shares set forth in this Agreement, relied solely upon the SEC Reports and the representations and warranties of the Company contained herein. Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Shares, except in compliance with the Securities Act and the rules and regulations promulgated thereunder and under this Agreement. 5.4 Registration or Exemption Requirements. Purchaser further acknowledges and understands that the Shares may not be resold or otherwise transferred except in a transaction registered under the Securities Act or unless an exemption from such registration is available. Purchaser is able to bear the economic risk of holding the Shares for an indefinite period of time and can afford a complete lost of its investment. Purchaser understands that until the Shares have been registered for resale by the Purchasers in compliance with applicable securities laws, the certificates evidencing the Shares will be imprinted with the legend set forth in Section 5.5 that prohibits the transfer of the Shares unless (a) such transaction is registered or such registration is not required or (b) if the transfer is pursuant to an exemption from registration, an opinion of counsel reasonably satisfactory to the Company is obtained to the effect that the transaction is not required to be registered or is so exempt. 5.5 Legend. Until and unless the Registrable Securities (as such term is hereinafter defined) are registered under the Securities Act and any applicable state securities or "blue sky" laws and regulations, and as permitted by law, each certificate representing the Registrable Securities shall bear substantially the following legend (in addition to any legends required under applicable state securities or "blue sky" laws): "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, OR ANY APPLICABLE STATE SECURITIES OR "BLUE-SKY" LAWS AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER SUCH ACT OR UNDER SUCH LAWS, OR PURSUANT TO AN EXEMPTION FROM SUCH REGISTRATION, AND ARE SUBJECT TO THE TERMS AND CONDITIONS OF THE COMMON STOCK PURCHASE AGREEMENT DATED MARCH __, 2002, BETWEEN 7

DISCOVERY LABORATORIES, INC., AND LABORATORIOS DEL Dr. esteve S.A., A COPY OF WHICH IS AVAILABLE UPON WRITTEN REQUEST OF THE CORPORATE SECRETARY OF DISCOVERY LABORATORIES, INC." "Registrable Securities" shall mean (i) the Shares and (ii) any Common Stock issued as a dividend or other distribution with respect to, or in exchange for or in replacement of, the Shares; provided, however, that "Registrable Securities" shall not include any securities sold by a person either pursuant to a registration statement or Rule 144 as promulgated by the SEC under the Securities Act, as such Rule may be amended from time to time, or any similar successor rule that may be promulgated by the SEC. 5.6 No Legal, Tax Or Investment Advice. Purchaser understands that nothing in this Agreement or any other materials presented to Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. Purchaser has consulted, at its own risk and expense, such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares. 5.7 Closing Date. All the representations and warranties made by the Purchaser in this Section 5 shall be true and complete from the date of this Agreement through the Closing Date and the Purchaser shall provide the Company, before the Closing, with any documents or information necessary for such representations and warranties to remain true and complete as of the Closing Date. 5.8 Compliance with Other Instruments. The execution and delivery of this Agreement, the purchase of the Shares and the performance by the Purchaser of all other obligations of the Purchaser contemplated hereby will not (i) violate any law, rule, regulation, judgment, order or decree applicable to Purchaser or (ii) require any consent, approval, authorization or order of, or filing with, any court or governmental agency or body. Purchaser is not subject to any restriction which would prohibit it from entering into or performing its obligations under this Agreement, except for such restrictions which would not, individually or in the aggregate, have a material adverse effect on the ability of Purchaser to perform its obligations under this Agreement. 5.9 Compliance with Insider Trading Rules. Purchaser acknowledges and agrees that it is aware, and that it will advise each of its affiliates and representatives that is provided any confidential information of the Company that the United States securities laws provide that any person who has received directly or indirectly from an issuer such as the Company material, non-public information is prohibited from purchasing or selling securities of such issuer or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities, and that violation of such prohibition may involve severe civil and criminal penalties. Accordingly, Purchaser will not directly or indirectly, through related parties or otherwise, purchase, trade, offer, pledge, sell, contract to sell or to purchase or sell or "short" or "short against the box" (as those terms are generally understood in the securities markets), or otherwise dispose of or acquire, any securities of the Company or options in respect of such securities. Purchaser further agrees not to provide any person with material, nonpublic information, received from the Company or its representatives, including any relative, associate, or other 8

individual who intends to, or may, (a) trade securities with respect to the Company which is the subject of such information or (b) otherwise directly or indirectly benefit from such information. 5.10 No Brokers. Purchaser represents and warrants that it has not "engaged," "consented to" or "authorized" any broker, finder or intermediary to act on its behalf, directly or indirectly, as a broker, finder or intermediary in connection with the transactions contemplated by this Agreement. Purchaser agrees to indemnify and hold the Company harmless from and against all fees, commissions or other payments owing to any such person or firm acting on behalf of such Purchaser hereunder. 5.11 Reliance on Representations. Purchaser acknowledges that the Company and its counsel are entitled to rely on the representations and warranties made above. 5.12 Pre-existing Registration Rights. Purchaser acknowledges that 1,765,608 shares of Common Stock (subject to adjustment in the case of a stock split or recapitalization of the Company and, potentially additional shares that shall be issuable upon the exercise of certain warrants which are issuable upon the certain contractual obligations of the Company) that have been previously issued by the Company, or are issuable by the Company upon the exercise of certain warrants, are subject to "piggyback" registration rights and that the holder(s) thereof may elect to exercise such rights in connection with any registration statement to be filed by the Company pursuant to Section 6, and that the exercise of any such rights, and the performance by the Company of its obligations in connection therewith shall not be a violation of the terms of this Agreement. 6. Registration Rights, Indemnification. As used herein, "Holder" shall mean the Purchaser or any subsequent valid transferee of the Registrable Securities of the Purchaser in accordance with the terms of this Agreement. 6.1 Required Registration. (a) At any time following one hundred eighty (180) days after the date of this Agreement, the Holders of Registrable Securities who hold and propose to sell Registrable Securities with an aggregate value of at least $500,000 shall have the right to require the Company to register under the Securities Act on Form S-3, or other comparable or successor form, such shares by delivering written notice thereof to the Company. All such registrations shall be non-underwritten. For so long as the Company may be obligated to effect a registration statement pursuant to this Section 6.1, the Company shall use reasonable efforts to be and remain eligible to use Form S-3 or other appropriate comparable or successor form under the Securities Act. (b) The Company shall be obligated to register Registrable Securities pursuant to this Section 6.1 on not more than one occasion during any twelve-month rolling period, or on more than two occasions in the aggregate; provided, however, that such obligation shall be deemed satisfied only when a registration statement covering all shares of Registrable Securities requested to be included in such registration statement by the Holders thereof, for sale in accordance with the method of disposition specified by the requesting Holders, shall have become effective or if the Holders participating in the registration withdraw from the registration. 9

(c) The Company shall be entitled to include in any registration statement referred to in this Section 6.1, for sale in accordance with the method of disposition specified by requesting holders, shares of Common Stock to be sold by the Company for its own account or for the account of other security holders of the Company, but, with respect to shares to be sold by the Company, only to the extent that such inclusion will not adversely affect, in the Company's good faith determination, the offering for the account of the Holders of Registrable Securities. (d) If, in the event of an offering pursuant to this Section 6.1, the Company, in its good faith discretion, or, in the event the offering is underwritten, the managing underwriter, shall be of the opinion that the inclusion of the Registrable Securities would adversely affect the marketing of the securities to be sold pursuant to such registration statement or would otherwise have a material adverse effect on the Company, the number of shares of Registrable Securities to be included in such registration statement may be limited and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (I) first, pro rata among the holders of Registrable Securities demanded to be registered therein by the Holders in proportion, as nearly as practicable, to the respective amounts of shares of Common Stock requested to be registered therein by such holders at the time of filing the registration statement; and (II) second, other securities requested to be registered in such registration, including, without limitation, securities requested to be registered therein by the Company and by any holders of "piggyback" registrations rights. 6.2 Incidental Registration. If the Company at any time (other than pursuant to Section 6.1) proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to registration statements on Forms S-4, S-8 or another form not available for registering the Registrable Securities for sale to the public, or which relate to employee benefit plans or with respect to corporate reorganizations or other transactions subject to Rule 145 of the Securities Act), each such time it will give written notice to all Holders of outstanding Registrable Securities of its intention so to do. Upon the written request of any such Holder, received by the Company within thirty (30) days after the giving of any such notice by the Company, to register any of its Registrable Securities, the Company will use its reasonable efforts to cause such Registrable Securities to be included in the registration statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition of such Registrable Securities so registered. If, in the event of an offering pursuant to this Section 6.2, the Company, in its good faith discretion, or, in the event the offering is underwritten, the managing underwriter, shall be of the opinion that the inclusion of the Registrable Securities would adversely affect the marketing of the securities to be sold pursuant to such registration statement or would otherwise have a material adverse effect on the Company, the number of shares of Registrable Securities to be included in such registration statement may be limited and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (I) first, the securities requested to be registered therein by the Company shall be included; (II) second, the securities demanded to be registered therein by the holders of "demand" registration rights; (III) third, pro rata among the other holders of shares of Common Stock, including the Registrable Securities, in proportion, as nearly as practicable, to the respective amounts of shares of Common Stock requested to be registered by such holders at the time of filing the registration statement. 10

6.3 Registration Procedures. If and whenever the Company is required by the provisions of Section 6.1 or 6.2 to effect the registration of any Registrable Securities under the Securities Act, the Company will, as expeditiously as reasonably possible: (a) prepare and file with the SEC a registration statement with respect to such securities as soon as reasonably practicable after delivery of the applicable notice, and in any event within thirty (30) days thereof, and use reasonable efforts to cause such registration statement to become effective within ninety (90) days after delivery of such notice and remain effective for the period of the distribution contemplated thereby (determined as hereinafter provided); provided, however, that that Company's obligation to file a registration statement, or cause such registration statement to become and remain effective, shall be suspended for a period not to exceed ninety (90) days in any twelve-month period if in the reasonable judgment of the Company's Board of Directors it would be detrimental to the Company to effect a registration at such time; (b) prepare and file with the SEC such amendments and supplements to such registration statement and the related prospectus as may be necessary to keep such registration statement effective for the period specified in paragraph (a) above and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement in accordance with the sellers' intended method of disposition set forth in such registration statement for such period; provided, however, the Holders hereby acknowledge that the Company may notify the Holders of the suspension of the use of the prospectus forming a part of the registration statement until such time as an amendment to such registration statement has been filed by the Company and declared effective by the SEC or until the Company has otherwise amended or supplemented such prospectus, and upon receipt of such notice the Holders shall immediately suspend the use of the prospectus and shall not offer or sell any securities pursuant to said prospectus during the period commencing at the time at which the Company gives the Holders notice of the suspension of the use of said prospectus and ending at the time the Company gives the Holders notice that Holders may thereafter effect sales pursuant to said prospectus. Notwithstanding anything herein to the contrary, the Company (i) shall not suspend use of the registration statement by Holders unless such suspension is in the good faith opinion of the Company and its counsel advisable under the federal securities laws and the rules and regulations promulgated thereunder; and (ii) shall use its best efforts to amend to such registration statement or amend or supplement such prospectus as soon as practicable to again permit sales pursuant to said prospectus; (c) furnish to each seller of Registrable Securities and to each underwriter, if applicable, such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such registration statement; (d) use its best efforts to register or qualify the Registrable Securities covered by such registration statement under the securities or "blue sky" laws of such jurisdictions as the sellers of Registrable Securities or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any 11

jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction; (e) promptly notify each seller of Registrable Securities and each underwriter, if applicable, under such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; and (f) if the offering is underwritten and at the request of any seller of Registrable Securities, use its best efforts to furnish on the date that Registrable Securities are delivered to the underwriters for sale pursuant to such registration: (i) an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters and to such seller, in form and substance as is customarily given in an underwritten public offering; and (ii) a letter dated such date from the independent public accountants retained by the Company, addressed to the underwriters and to such seller, in form and substance as is customarily given in an underwritten public offering. For purposes of Section 6.3(a) and (b), the period of distribution of Registrable Securities in any registration shall be deemed to extend until the earlier of the sale of all Registrable Securities covered thereby and one hundred twenty (120) days after the effective date thereof (the "Registration Period"). 6.4 Expenses. All expenses incurred by the Company in complying with Sections 6.1 and 6.3 (to the extent applicable), including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including counsel fees) incurred in connection with complying with state securities or "blue sky" laws, fees of the NASD, transfer taxes, fees of transfer agents and registrars, but excluding Selling Expenses, are called "Registration Expenses". All underwriting discounts and selling commissions applicable to the sale of Registrable Securities are called "Selling Expenses". The Company will pay all Registration Expenses in connection with each registration statement under Section 6.1. All (i) Selling Expenses, (ii) fees and disbursements of counsel for the sellers of Registrable Securities and (iii) any expenses incurred in complying with Section 6.2, in connection with each such registration statement shall be borne by the participating sellers on a pro rata basis based on the number of Registrable Securities included in such registration statement. 6.5 Indemnification and Contribution. (a) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Section 6.1 or 6.2, to the extent permitted by applicable law, the Company will indemnify and hold harmless each seller of such Registrable Securities thereunder, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls such seller or underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages, actions or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act or other 12

applicable Federal or State securities or "blue sky" laws, to the extent that such losses, claims, damages, actions or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such seller, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable, to any such indemnitee if and to the extent that any such loss, claim, damage, action or liability arises out of or is based upon an (i) untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by or on behalf of such indemnitee in writing or (ii) such untrue statement or alleged untrue statement or omission or alleged omission was contained in a preliminary or earlier effective prospectus and corrected in a final or amended prospectus, and such indemnitee failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the buyer of such Registrable Securities; provided, further, that the indemnity agreement contained in this Section 6.5(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld. (b) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Section 6.1 or 6.2, to the extent permitted by applicable law, each seller of such Registrable Securities thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company, each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the Securities Act, against all losses, claims, damages, actions or liabilities, joint or several, to which the Company or such officer, director, underwriter or controlling person may become subject under the Securities Act or other applicable Federal or State securities or "blue sky" laws, to the extent that such losses, claims, damages, actions or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer, director, underwriter and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that such seller will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage, action or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to the Company by or on behalf of such seller specifically for use in such registration statement or prospectus; provided, further, that the indemnity agreement contained in this Section 6.5(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of such seller, which consent shall not be 13

unreasonably withheld; provided, that such consent shall not be required if the settlement shall include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 6.5 and shall only relieve it from any liability which it may have to such indemnified party under this Section 6.5 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 6.5 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have provided the Company with a legal opinion of counsel reasonably satisfactory to the Company and its counsel that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred; provided, further, that the Company shall not have any reimbursement obligation for the expenses and fees of more than one such separate counsel for all indemnitees. (d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any Holder of Registrable Securities exercising rights under this Agreement, or any controlling person of any such Holder, makes a claim for indemnification pursuant to this Section 6.5 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 6.5 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling Holder or any such controlling person in circumstances for which indemnification is provided under this Section 6.5; then, and in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other, as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to 14

information and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case, (A) no such Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered by it pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 6.6 Changes in Common Stock. If, and as often as, there is any change in the Common Stock by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue with respect to the Common Stock as so changed. 6.7 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC that may at any time permit the sale of the Registrable Securities to the public without registration, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act; (b) use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to each Holder of Registrable Securities forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as such Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing such Holder to sell any Registrable Securities without registration. 6.8 Certain Holder Obligations. (a) As a condition to the inclusion of its Registrable Securities in a registration effected pursuant to Section 6.1 or 6.2, the Holders will promptly provide the Company with such information as the Company shall reasonably request in order to prepare the applicable registration statement for such registration, including, but not limited to, information regarding the Holders, the securities of the Company owned beneficially or of record by the Holders, the distribution proposed by the Holders, a customary selling securityholders questionnaire and, upon the Company's request, the Holders shall provide such information in writing and signed by the Holders and stated to be specifically for inclusion in the applicable registrations. In the event that the distribution of the Common Stock covered by the applicable registration statement shall be effected pursuant to an underwritten offering as contemplated by Section 6.2, the inclusion of the Registrable Securities shall be conditioned on the Holders' execution and delivery of a customary underwriting agreement with terms and conditions reasonably satisfactory to the Company with respect thereto. (b) The Holders shall not take any action with respect to any distribution deemed to be made pursuant to any registration statement pursuant to Section 6.1 or 6.2, which would constitute a violation of Regulation M under the Exchange Act. 15

(c) If, at the end of the Registration Period, the Holders have Registrable Securities which were included in such registration statement, the Holders shall discontinue sales of such securities pursuant to the registration statement and prospectus upon receipt of notice from the Company of its intention to remove from registration the shares covered by registration statement which remain unsold (as permitted under the provisions of this Section 6), and the Holders shall notify the Company of the number of shares registered which remain unsold promptly upon receipt of such notice from the Company. (d) The Holders shall have no right to take any action to restrain, enjoin or otherwise delay any registration as a result of any controversy that may arise with respect to the interpretation or implementation of the terms of this Section 6. (e) The Registrable Securities shall not be transferable in the absence of registration under the Securities Act and any applicable state securities or "blue sky" laws and regulations or an exemption therefrom or in the absence of compliance with any term of the Agreement. (f) Purchaser hereby covenants with the Company not to make any sale of the Registrable Securities except either (i) a sale of Registrable Securities in accordance with the Registration Statement, in which case the Purchaser covenants to comply with the requirement of delivering a current prospectus, (ii) a sale of Registrable Securities in accordance with Rule 144, in which case the Purchaser covenants to comply with Rule 144 and to deliver such additional certificates and documents as the Company may reasonably request or (iii) in accordance with another exemption from the registration requirements of the Securities Act. The legend set forth in Section 5.5 will be removed from a certificate representing Registrable Securities following and in connection with any sale of Registrable Securities or pursuant to subsection (i) or (ii) hereof but not in connection with any sale of Registrable Securities pursuant to subsection (iii) hereof. 6.9 Termination of Registration Rights. Notwithstanding Section 6.3, the obligations of the Company to register shares of Registrable Securities under Section 6.1 or 6.2 for a Holder of Registrable Securities shall terminate on the date on which such Holder can, in the reasonable opinion of counsel to the Company, sell all shares of its Registrable Securities in a three-month period without registration under the Securities Act pursuant to Rule 144 under the Securities Act. 7. Additional Agreements. 7.1 Short Sales, etc. Purchaser represents and agrees that, during the period from February 1, 2002 through the date of this Agreement, Purchaser and its Affiliates (as hereinafter defined) did not and, from the date hereof until the second anniversary of the date of this Agreement, Purchaser will not, and shall cause its Affiliates not to, execute or effect or cause to be executed or effected any "short sale" (as defined in Rule 3b-3 of the Exchange Act) of Common Stock or any hedging transaction in which the other party to such transaction is reasonably likely to engage in such a short sale as a direct result of such transaction. For the purposes of this Agreement, "Affiliate" shall have the meaning given such term in Rule 12b of the Exchange Act. 16

7.2 Restriction on Purchase of Common Stock. Until the expiration or termination of the Collaboration Agreement, Purchaser will not, and shall cause its Affiliates not to, purchase or become the beneficial owner of any shares of Common Stock which results in Purchaser and its Affiliates beneficially owning more than nineteen percent (19%) of the issued and outstanding shares of Common Stock; provided, however, that (a) nothing in this Section shall prevent Purchaser and its Affiliates from acquiring Common Stock contemplated by the Transaction Agreements and (b) Purchaser shall not be deemed to violate this Section as a result of any reorganization, recapitalization, stock repurchase, stock combination or other similar transaction effected by the Company with respect to the Common Stock if Purchaser and its Affiliates beneficially owned less than 19% of the issued and outstanding shares of Common Stock before giving effect to such transaction. For the purposes of this Section 7.2, "beneficial ownership" shall be determined in accordance with Rule 13d-3 promulgated under the Exchange Act. 7.3 Restrictions on Sale of Shares.

(b) If, at any time prior to the third anniversary of the date of this Agreement, Purchaser proposes to sell Shares constituting one percent (1.0%) or more of the outstanding shares of Common Stock, then Purchaser shall first offer to sell such Shares of the Company, and the parties agree to negotiate in good faith to reach an agreement on the purchase price and other terms of the sale of such Shares to the Company. If the parties are not able to reach such an agreement within 30 business days (a business day shall be any day other than a Saturday, Sunday or legal holiday on which banks in New York and Spain are open for the conduct of their banking business), then Purchaser shall be free to proceed with such sale to a third party so long as it complies with any other applicable terms of this Agreement. (c) Until the expiration or termination of the Collaboration Agreement, Purchaser will not knowingly sell the Shares to a person or entity which actively sells, distributes, markets, develops, or produces a pharmaceutical product which directly competes with the Company. In any event, this subsection (c) shall not prevent Purchaser from selling the Shares in open-market transactions. (d) The restrictions under this Section shall not be applicable to any transfers of the Shares to any Affiliate of Purchaser, so long as such Affiliate agrees in advance of such transfer in an enforceable written instrument to be bound by all the terms and conditions of this Agreement as if it were Purchaser and a party hereto, which instrument shall be delivered a reasonably practicable time prior to such sale or transfer. 7.4 Voting Agreement. Until the earlier of (i) such time that Purchaser beneficially owns less than 1.5% of the issued and outstanding shares of Common Stock of the Company, and (ii) the completion of the Company's annual meeting of shareholders for the calendar year 2003, at each annual meeting of the shareholders of the Company or in connection with any other meeting or action by written consent in lieu of a meeting of the shareholders of the Company, Purchaser shall vote or act with respect to all shares of Common Stock beneficially owned by it (x) in favor of all persons nominated by the then current Board of 17

Directors of the Company for election to the Board of Directors of the Company and (y) in accordance with the recommendations of the Board of Directors with respect to any other issue; provided, that this clause (y) shall not apply to any issue that is directly related to the matters which are subject to the Transaction Agreements. The voting agreement contained in this Section 7.4 is irrevocable to the extent permitted by applicable law and is coupled with an interest. Until the earlier of (i) such time that Purchaser beneficially owns less than 2.5% of the issued and outstanding shares of Common Stock of the Company, and (ii) three years after the date of this Agreement, at and in relation to each annual meeting of the shareholders of the Company or in connection with any other meeting or action by written consent in lieu of a meeting of shareholders of the Company, Purchaser will not actively oppose any items referred to in clauses (x) and (y) above. 7.5 Continuation of Certain Restrictions. If at any time prior to the third anniversary of the date of this Agreement, Purchaser transfers Shares in accordance with the provisions of this Agreement, Purchaser shall not effect such transfer unless the transferee agrees in an enforceable written instrument to be bound by the terms and conditions of Sections 7.1, 7.3(c), and 7.4; provided, however, that (i) such transferee shall not be bound to any greater extent as to duration of time or otherwise than Purchaser is bound under such Sections on the date of this Agreement and (ii) this Section 7.5 shall not apply to any transfer by Purchaser to a transferee that will own one-half of one percent (.5%) or less of the Company's outstanding shares of Common Stock after giving effect to such transfer. 8. Miscellaneous. 8.1 Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and do not constitute a part of this Agreement. 8.2 Choice of Law; Venue.

In the event that a judicial proceeding is necessary, the sole forum for resolving disputes arising out of or relating to this Agreement is the Supreme Court of the State of New York in and for the County of New York or the Federal Courts for such state and county, and all related appellate courts (collectively, the "New York Courts"). The parties hereby irrevocably and unconditionally consent to the jurisdiction of such courts. (b) Each of the parties hereby irrevocably and unconditionally consents to venue in the New York Courts, and hereby irrevocably and unconditionally waives any objection to the laying of venue of any judicial proceeding in the New York Courts, and agrees not to plead or claim in any such New York Court that any such judicial proceeding brought in any such court has been brought in an inconvenient forum. (c) Each of the parties waives the right to a trial by jury in any action under this Agreement or any judicial proceeding arising out of the transactions contemplated hereby, regardless of which party initiates such judicial proceeding. 18

No amendment, modification, waiver, discharge or termination of any provision of this Agreement nor consent to any departure by the Purchasers or the Company therefrom shall in any event be effective unless the same shall be in writing and signed by the party to be charged with enforcement, and then shall be effective only in the specific instance and for the purpose for which given. No course of dealing between the parties hereto shall operate as an amendment of, or a waiver of any right under, this Agreement. 8.6 Severability.

         Discovery Laboratories & Esteve Expand Relationship to Develop
                    and Commercialize Surfaxin(R) in Europe

Doylestown, PA -- March 7, 2002 -- Discovery Laboratories, Inc. (Nasdaq: DSCO),
a late-stage specialty pharmaceutical company leveraging its platform technology
in humanized lung surfactants to develop potential novel respiratory therapies
and pulmonary drug delivery products, today announced a significantly expanded
alliance with Laboratorios Del Dr. Esteve S.A ("Esteve") for the development,
marketing and sales of Surfaxin throughout Europe, Central America and South
America. This expanded collaboration supersedes existing sublicense and supply
agreements between Discovery and Esteve in October 1999, which limited the
European territory to Southern Europe.

Through the alliance, Esteve will market Surfaxin for respiratory distress
syndrome (RDS) in premature infants, meconium aspiration syndrome (MAS) in full
term babies, and acute lung injury/acute respiratory distress syndrome
(ALI/ARDS) in adults. Currently, Discovery is conducting two phase 3 clinical
trials for RDS, a phase 3 trial for MAS and a Phase 2 trial for ARDS. In
addition, the new arrangement anticipates an opportunity for Esteve to negotiate
licenses for the development and marketing of future Discovery products in the
above territories.

The agreement provides for an up-front licensing fee to Discovery of $500,000, a
purchase by Esteve of $4 million of Discovery's common stock at $4.867 per share
(a 50% premium to the trailing 30 day average determined as of March 4, 2002),
and milestone payments to be made to Discovery tied to attaining specific
regulatory approvals for Surfaxin. Additionally, Esteve will sponsor clinical
trial costs for ALI/ARDS to obtain European Agency for the Evaluation of
Medicinal Products (EMEA) approval for marketing in Europe. Under the prior
arrangement, Esteve had provided support for Discovery's multinational clinical
trials for RDS and MAS in Europe. Discovery retains manufacturing rights and, as
part of the collaboration, Esteve has agreed to an exclusive supply agreement,
whereby, they will purchase Surfaxin drug product from Discovery. Discovery will
receive, as a potential ongoing revenue stream, a transfer price based on sales
of Surfaxin by Esteve and/or its sublicensee(s).

                                    - more-

Antoni Esteve, Ph.D., Esteve's Director of Scientific and Commercial Operations, commented, "Esteve is very proud to expand our collaboration with Discovery. Over the last several years, we have increased our confidence in the significant potential of humanized surfactants to improve therapies for the treatment of babies suffering from respiratory disorders, adults suffering from acute respiratory distress syndrome, and the downstream possibility of aerosolized surfactants treating a broader range of respiratory diseases and as a drug delivery platform. Our additional investment in Discovery supports this confidence and gives Esteve the opportunity to broaden our product portfolio for the medical communities we serve." "We have worked closely with Esteve since 1999 and they have been an excellent partner," said Robert J. Capetola, Ph.D., President and Chief Executive Officer of Discovery. "Expanding our relationship to now include all of Europe was a natural progression for us. Esteve has a superb reputation of marketing innovative pharmaceuticals, and we are pleased to be represented by their professional team to effectively market and distribute Surfaxin to the critical care hospital community. In combination with our recent Quintiles Transnational collaboration, Discovery now has in place the sales and marketing infrastructure to bring Surfaxin to the critical care markets in Europe, the United States and Latin America. Discovery will establish and maintain the global brand strategy for Surfaxin, while our collaborators will be responsible for regional implementation. Our objective is to have a uniform, recognizable Discovery/Surfaxin image visible to the critical care markets throughout the world. Meanwhile, Discovery will record a significant share of the revenues, and in the case of the United States, Discovery should generate margins typical of a fully-integrated specialty pharmaceutical company." Human lung surfactants are substances naturally present in the lung tissue and are essential to the lungs' ability to absorb oxygen. Discovery's Surfaxin is the first humanized peptide-based surfactant that mimics the human surfactant protein B, considered physiologically the most important of the four major proteins found in human lung surfactants. RDS in premature infants is a breathing disorder in which the lungs of infants do not stay open due to an insufficient amount of surfactant, which is produced naturally in normally developing infants as their lungs mature. Approximately 270,000 cases of RDS in premature infants occur in the developed world annually. MAS results when a full-term baby inhales meconium, a material produced in the intestine of a full-term baby before birth. Severe respiratory distress is a result and there are currently no approved therapies anywhere in the world. Approximately 60,000 cases of MAS occur in the developed world annually. ALI/ARDS is a life-threatening disorder for which there are currently no approved therapies anywhere in the world. ALI/ARDS is characterized by an excess of fluid in the lungs and decreased oxygen levels in the patient. One prominent characteristic is the destruction of surfactants. These conditions are caused by events such as smoke inhalation, near drowning, industrial accidents and other traumas and illnesses including pneumonia and septic shock. Because there are no approved treatments, the mortality rate can range from 35% to 50%. There are estimated to be between 150,000 and 250,000 ALI/ARDS patients per year in each of the U.S. and Europe.
