▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Dear Sir or Madam:

Neose Technologies, Inc., a Delaware corporation (the “Company”), proposes to sell to certain purchasers, pursuant to the terms of this Placement Agent Agreement (this “Agreement”) and Subscription Agreements substantially in the form of Exhibit A attached hereto (the “Subscription Agreements”) entered into with the purchasers identified therein (each a “Purchaser” and, collectively, the “Purchasers”), an aggregate of 2,888,889 shares of Common Stock, par value $.01 per share (the “Common Stock”), of the Company. The aggregate of 2,888,889 shares so proposed to be sold is hereinafter referred to as the “Stock.” The Company hereby confirms its agreement with ▇.▇. ▇▇▇▇▇▇ Securities Inc. (“JPMorgan”) as follows (certain terms used herein are defined in Section 13 hereof):

1. AGREEMENT TO ACT AS PLACEMENT AGENT; PLACEMENT OF SECURITIES. On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the terms and conditions of this Agreement:

(a) The Company hereby authorizes JPMorgan to act as its exclusive agent (in such capacity, the “Placement Agent”) to solicit offers for the purchase of all or part of the Stock from the Company in connection with the proposed offering of the Stock (the “Offering”). Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing Date, the Company shall not, without the prior consent of the Placement Agent, solicit or accept offers to purchase Stock (other than pursuant to the exercise of options or warrants to purchase shares of Common Stock that are outstanding at the date hereof) otherwise than through the Placement Agent.

(b) The Placement Agent agrees, as agent of the Company, to use its best commercially practicable efforts to solicit offers to purchase the Stock from the Company on the terms and subject to the conditions set forth in the Base Prospectus (as defined below) and the Prospectus Supplement (as defined below). The Placement Agent shall use its best commercially practicable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Stock has been solicited by the Placement Agent and accepted by the Company, but the Placement Agent shall not, except to facilitate such acceptance by the Company or as otherwise provided in this Agreement, be obligated to disclose the identity of any

potential purchaser or have any liability to the Company in the event any such purchase is not consummated for any reason. Under no circumstances will the Placement Agent be obligated to purchase any Stock for its own account and, in soliciting purchases of Stock, the Placement Agent shall act solely as the Company’s agent and not as principal.

(c) Subject to the provisions of this Section 1, offers for the purchase of Stock may be solicited by the Placement Agent as agent for the Company at such times and in such amounts as the Placement Agent deems advisable. The Placement Agent shall communicate to the Company, orally or in writing, each reasonable offer to purchase Stock received by it as agent of the Company. The Company shall have the sole right to accept offers to purchase the Stock and may reject any such offer, in whole or in part. The Placement Agent shall have the right, in its discretion reasonably exercised, without notice to the Company, to reject any offer to purchase Stock received by it, in whole or in part, and any such rejection shall not be deemed a breach of its agreement contained herein.

(d) The purchases of the Stock by the Purchasers may be evidenced by the execution of the Subscription Agreements.

(e) Concurrently with the execution and delivery of this Agreement, the Company, the Placement Agent, and JPMorgan Chase Bank, as escrow agent (the “Escrow Agent”), shall enter into an Escrow Agreement substantially in the form of Exhibit B attached hereto (the “Escrow Agreement”), pursuant to which an escrow account will be established, at the Company’s expense, for the benefit of the Company and the Purchasers (the “Escrow Account”). Prior to the Closing Date (as hereinafter defined), certain of the Purchasers will deposit in the Escrow Account an amount equal to the price per share for the Stock as determined by the Subscription Agreements multiplied by the number of shares of Stock to be purchased by such Purchaser (the “Escrow Funds”).

(f) As compensation for services rendered, on the Closing Date (as defined below) the Company shall pay to the Placement Agent by wire transfer of immediately available funds to an account or accounts designated by the Placement Agent, an amount equal to five and three quarters percent (5.75%) of the gross proceeds received by the Company from the sale of the Stock.

(g) No Stock which the Company has agreed to sell pursuant to this Agreement shall be deemed to have been purchased and paid for, or sold by the Company, until such Stock shall have been delivered to the Purchaser thereof against payment by such Purchaser. If the Company shall default in its obligations to deliver Stock to a Purchaser whose offer it has accepted, and from which it has received payment for such Stock, the Company shall indemnify and hold the Placement Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company.

2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to, and agrees with, the Placement Agent and the Purchasers that:

(a) The Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), and has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on such Form (Registration File No. 333-106327), which became effective as of June 26, 2003, for the registration under the Securities Act of the Stock for the transactions described therein, including the Offering. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies in all other material respects with said Rule. The Company will file with the Commission, pursuant to Rule 424(b) under the Securities Act, a supplement to the form of prospectus included in such registration statement relating to the Offering and has advised the Placement Agent of all further information (financial and other) with respect to the Company to be set forth in such supplement. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the “Registration Statement;” such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus;” and the supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) under the Securities Act and the rules and regulations of the Commission promulgated thereunder (the “Rules and Regulations”) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus Supplement.” Any reference herein to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”) pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing by the Company of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, on or before the Closing Date (as defined below), incorporated or deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement has been issued, and, to the Company’s knowledge, no proceeding for any such purpose is pending, has been initiated or is threatened by the Commission.

(b) The Registration Statement contains all exhibits and schedules required by the Securities Act. The Registration Statement, at the time it became effective, complied in all

material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Each of the Base Prospectus and the Prospectus Supplement, as of its respective date, complies or will comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations. The Base Prospectus and the Prospectus Supplement, taken as a whole, as amended or supplemented, will not contain as of the date of the Prospectus Supplement and the Closing Date, any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable rules and regulations promulgated thereunder, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and any further documents so filed and incorporated by reference in the Base Prospectus or Prospectus Supplement prior to the consummation of the Offering, when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the applicable rules and regulations promulgated thereunder, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the Company makes no representations or warranties in this Section 2(b) with respect to statements or omissions furnished in writing to the Company specifically for use in the Registration Statement or the Prospectus Supplement pursuant to Section 15 hereof. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date of this Agreement and prior to the Closing Date which represent, individually or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission.

(c) The Company has delivered, or will as promptly as practicable deliver, to the Placement Agent complete conformed copies of the Registration Statement and of each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement (without exhibits) and the Base Prospectus and the Prospectus Supplement, as amended or supplemented, in such quantities and at such places as the Placement Agent reasonably requests. The Company has not distributed and will not distribute, prior to the completion of the distribution of the Stock, any offering material in connection with the offering and sale of the Stock other than the Base Prospectus and the Prospectus Supplement or the Registration Statement and copies of the documents incorporated by reference therein.

(d) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, has full corporate power and corporate authority to own or lease its properties and conduct its business as described in the Registration Statement, the Base Prospectus or the Prospectus Supplement and as now being conducted, and is duly qualified as a foreign corporation and in good standing in all jurisdictions in which the

character of the property owned or leased or the nature of the business transacted by it makes qualification necessary, except where failure to be so qualified could not reasonably be expected to have a material adverse effect on the business, properties, financial condition or results of operations of the Company (a “Material Adverse Effect”). The Company has no subsidiaries and has never had any operating subsidiaries.

(e) The Stock being sold hereunder has been duly authorized and, when issued and paid for in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and nonassessable and free of any preemptive or similar rights (except those that have been waived by the holder thereof) and will conform to the description thereof contained in the Registration Statement, the Base Prospectus and the Prospectus Supplement.

(g) The Company has full corporate power and authority to execute and deliver the Transaction Documents and to consummate the transactions contemplated herein and therein. The Transaction Documents have been duly authorized and validly executed and delivered by the Company and constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except as the indemnification agreements of the Company herein may be legally unenforceable.

(h) None of the execution and delivery of the Transaction Documents, the issuance and sale of the Stock by the Company hereunder and thereunder, the fulfillment of the terms of the Transaction Documents or the consummation of the transactions contemplated by the Transaction Documents, will (i) violate any law, rule, regulation, judgment, injunction, decree, determination, award or order of any court or governmental agency or instrumentality, domestic or foreign, or (ii) conflict with or result in any breach of any of the terms of or constitute a default (with or without the giving of notice or the passage of time or otherwise) under, or result in the termination of or the creation or imposition of any mortgage, lien, security interest or other charge or encumbrance of any nature under the terms of: (A) any material contract or agreement to which the Company is a party or by which the Company or any of the assets and properties of

(i) There is no franchise, contract, lease, instrument or other document of a character required by the Securities Act or the Rules and Regulations to be described in the Registration Statement, the Base Prospectus and the Prospectus Supplement, or to be filed as an exhibit to the Registration Statement, which is not described or filed as required; and all statements summarizing any such franchises, contracts, leases, instruments or other documents or legal matters contained in the Registration Statement are accurate and complete in all material respects.

(l) As of their respective dates, the financial statements of the Company, together with related notes and schedules, included or incorporated by reference in the Registration

Statement, the Base Prospectus or the Prospectus Supplement complied and will comply in form in all material respects with applicable accounting requirements and the published rules and regulations of the Commission with respect thereto. Such financial statements and related notes and schedules have been prepared in accordance with United States generally accepted accounting principles, consistently applied, during the period involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and its results of operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments).

(m) Except as set forth in the Registration Statement, the Base Prospectus or the Prospectus Supplement, there is no material legal or governmental proceeding pending or, to the knowledge of the Company, threatened, to which the Company is a party or of which the business or property of the Company is subject that is not disclosed in the Registration Statement, the Base Prospectus or the Prospectus Supplement under the heading “Legal Proceedings.” There are no requests for confidential treatment of information currently pending before the Commission.

The properties of the Company are, in the aggregate, in good repair (reasonable wear and tear excepted), and suitable for their respective uses. To the Company’s knowledge, any real property held under lease by the Company is held under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the conduct of the business of the Company. The Company owns or leases all such properties as are necessary to its business or operations as now conducted.

Each “pension plan” (as defined in ERISA) for which the Company would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and nothing has occurred, whether by action or by failure to act, which could cause the loss of such qualification.

(s) The Company has made all filings, applications and submissions required by, and possesses all approvals, licenses, certificates, certifications, clearances, consents, exemptions, orders, permits and other authorizations required to be issued by, the appropriate federal, state or foreign regulatory authorities in order for the Company to conduct its business (collectively, “Permits”), except for such Permits which the failure to obtain could not reasonably be expected to have a Material Adverse Effect, and is in compliance in all material respects with the terms and conditions of all such Permits; all of such Permits held by the Company are valid and in full force and effect; there is no pending or, to the knowledge of the Company, threatened action, suit, claim or proceeding which may cause any such Permit to be limited, revoked, cancelled, suspended, modified or not renewed and the Company has not received any notice of proceedings relating to the limitation, revocation, cancellation, suspension, modification or non-renewal of any such Permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could reasonably be expected to have a Material Adverse Effect,

whether or not arising from transactions in the ordinary course of business, except as described in the Registration Statement, the Base Prospectus or the Prospectus Supplement.

(t) KPMG LLP, who have certified certain financial statements of the Company and delivered their report with respect to the audited consolidated financial statements and schedules included in the Base Prospectus, the Prospectus Supplement or the Registration Statement, or incorporated by reference therein, are independent public accountants with respect to the Company within the meaning of the Securities Act and the Rules and Regulations.

(v) The Company maintains a system of internal accounting controls that the Company reasonably believes are sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability of assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(w) Neither the Company nor any of its officers or directors, or to the Company’s knowledge, any of their affiliates (as such term is defined in Rule 405 under the Securities Act), has taken or will take, directly or indirectly, any action designed or intended to stabilize or manipulate the price of any security of the Company, or which caused or resulted in, or which might in the future reasonably be expected to cause or result in, stabilization or manipulation of the price of the Common Stock.

All of such patents, registered trademarks and registered copyrights owned by the Company have been duly registered in, filed in or issued by the United States Patent and Trademark Office, the United States Register of Copyrights or the corresponding offices of other jurisdictions and have been maintained and renewed in accordance with all applicable provisions of law and administrative regulations in the United States and all such jurisdictions, except where the failure to do so could not reasonably be expected to have a Material Adverse Effect. All material licenses or other material agreements under which (i) the Company is granted rights in Intellectual Property, other than Intellectual Property generally available on commercial terms from other sources, and (ii) the Company has granted rights to others in Intellectual Property owned or licensed by the Company, are, to the knowledge of the Company, in full force and effect and, to the knowledge of the Company, there is no material default by the Company thereto.

(a) (i) To make no further amendment or supplement prior to the Closing Date to the Registration Statement or any amendment or supplement to the Prospectus Supplement, which shall be reasonably disapproved by the Placement Agent in good faith promptly after reasonable notice thereof; (ii) for so long as the delivery of a prospectus is required in connection with the offering or sale of the Stock, to advise the Placement Agent promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Prospectus Supplement or any amended Prospectus Supplement has been filed and to furnish the Placement Agent with copies thereof; (iii) to use its best commercially practicable efforts to file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 15 or 15(d) of the Exchange Act subsequent to the date of the Prospectus Supplement and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Stock; (iv) to advise the Placement Agent, promptly after it receives notices thereof, (x) of any request by the Commission to amend the Registration Statement or to amend or supplement the Prospectus Supplement or for additional information relating thereto and (y) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any order directed at any Incorporated Document or any amendment or supplement thereto or any order preventing or

suspending the use of the Base Prospectus or the Prospectus Supplement or any amendment or supplement thereto, of the suspension of the qualification of the Stock for offering or sale in any jurisdiction, of the institution or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or Prospectus Supplement or for additional information relating thereto; and, (v) in the event of the issuance of any stop order or of any order preventing or suspending the use of the Base Prospectus or Prospectus Supplement or suspending any such qualification, promptly to use its best commercially practicable efforts to obtain the withdrawal of such order.

(b) To comply with the Securities Act and the Exchange Act, and the rules and regulations thereunder, so as to permit the completion of the distribution of the Stock as contemplated in the Transaction Documents and the Prospectus Supplement. If during the period in which a prospectus is required by law to be delivered by a Placement Agent or a dealer in connection with the distribution of Stock contemplated by the Prospectus Supplement, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Placement Agent or counsel for the Placement Agent, it becomes necessary to amend or supplement the Prospectus Supplement in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus Supplement is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus Supplement to comply with any law, the Company promptly will prepare and file with the Commission, and furnish at its own expense to the Placement Agent and to such dealers, an appropriate amendment to the Registration Statement or supplement to the Prospectus Supplement so that the Prospectus Supplement as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus Supplement will comply with such law. Before amending the Registration Statement or supplementing the Base Prospectus in connection with the Offering, the Company will furnish the Placement Agent with a copy of such proposed amendment or supplement and will not file such amendment or supplement to which the Placement Agent reasonably objects.

(c) To furnish promptly to the Placement Agent and to counsel for the Placement Agent, upon request, a copy of the Registration Statement as originally filed with the Commission, and each amendment thereto filed with the Commission, including all consents and exhibits filed therewith.

(d) To deliver promptly to the Placement Agent such number of the following documents as the Placement Agent shall reasonably request: (i) conformed copies of the Registration Statement as originally filed with the Commission and each amendment thereto (in each case excluding exhibits), (ii) the Base Prospectus, (iii) the Prospectus Supplement (not later than 10:00 A.M., New York time, on the second Business Day following the execution and delivery of this Agreement) and any amendment or supplement thereto (not later than 10:00 A.M., New York City time, on the Business Day following the date of such amendment or supplement); and (iv) any document incorporated by reference in the Base Prospectus or Prospectus Supplement. The Company will pay the expenses of printing or other production of all documents relating to the Offering.

(e) To make generally available to its stockholders as soon as practicable, but in any event not later than eighteen months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), an earnings statement of the Company (which need not be audited) complying with Section 11(a) of the Securities Act and the Rules and Regulations (including, at the option of the Company, Rule 158).

(f) To pay the fee, if any, of the National Association of Securities Dealers, Inc. (“NASD”) in connection with its review of the Offering.

(g) Not to directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock for a period of 90 days from the date of the Prospectus Supplement without the prior written consent of JPMorgan, other than (i) the Company’s sale of the Stock hereunder, (ii) the issuance of shares or options to purchase shares pursuant to qualified stock option plans, currently outstanding options, warrants or rights, (iii) securities issued to a collaborative partner of the Company solely in connection with a corporate partnering transaction; provided, however, that before issuing any shares to a collaborative partner, the Company shall obtain from such collaborative partner an agreement to be bound by a letter substantially in the form of Exhibit D, pursuant to which such collaborative partner shall agree not to directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock for a period of 90 days from the date of the Prospectus Supplement, without the prior written consent of JPMorgan; or (iv) in connection with a Sale of the Company. The Company will cause each of its executive officers and directors listed on Exhibit C hereto to furnish to the Placement Agent, prior to the Closing Date, a letter, substantially in the form of Exhibit D hereto, pursuant to which each such person shall agree not to directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock for a period of 90 days from the date of the Prospectus Supplement, without the prior written consent of JPMorgan, other than the exercise of currently outstanding options or in connection with a Sale of the Company.

(h) Prior to the Closing Date, to furnish to the Placement Agent, as soon as they have been prepared, copies of any unaudited interim consolidated financial statements of the Company for any periods subsequent to the periods covered by the financial statements appearing or incorporated by reference in the Base Prospectus, the Prospectus Supplement or the Registration Statement.

(i) Prior to the Closing Date, not to issue any press release or other communication directly or indirectly or hold any press conference with respect to the Company, its condition, financial or otherwise, or earnings, business affairs or business prospects (except for routine oral marketing communications in the ordinary course of business and consistent with the past practices of the Company and of which the Placement Agent is notified), without the prior written consent of the Placement Agent, unless in the judgment of the Company and its counsel,

and after notification to the Placement Agent, such press release or communication is required by law.

(k) To engage and maintain, at its expense, a registrar and transfer agent for the Stock.

5. PAYMENT OF EXPENSES. The Company agrees with the Placement Agent to pay (a) the costs incident to the authorization, issuance, sale, preparation and delivery of the Stock to the Purchasers and any taxes payable in that connection; (b) the costs incident to the Registration of the Stock under the Securities Act; (c) the costs incident to the preparation, printing and distribution of the Registration Statement, Base Prospectus and Prospectus Supplement and any amendments and exhibits thereto or any document incorporated by reference therein, and the costs of printing, reproducing and distributing, the Transaction Documents by mail, telex or other means of communication; (d) the fees and expenses incurred in connection with filings, if any, made with the NASD; (e) any applicable listing or other fees; (f) all fees and expenses of the registrar and transfer agent of the Stock; (g) the fees and expenses of the Escrow Agent incurred pursuant to the Escrow Agreement; (h) all other costs and expenses incident to the performance of the obligations of the Company under the Transaction Documents (including, without limitation, the fees and expenses of the Company’s counsel and the Company’s independent accountants); and (i) the reasonable fees and actual out-of-pocket expenses of counsel for the Placement Agent; provided that, except as otherwise provided in this Section 5 and in Section 9, the Placement Agent shall pay its own costs and expenses.

6. CONDITIONS TO THE OBLIGATIONS OF THE PLACEMENT AGENT AND THE SALE OF THE STOCK. The obligations of the Placement Agent and the closing of the sale of the Stock hereunder are subject to the accuracy, when made and on the Closing Date, of the representations and warranties on the part of the Company contained herein, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company in all material respects to the extent not otherwise qualified by materiality, and in all respects to the extent qualified by materiality, of their obligations hereunder, and to each of the following additional terms and conditions:

(a) No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been initiated or threatened by the Commission, and any request for additional information on the part of the Commission (to be

included in the Registration Statement, the Base Prospectus or the Prospectus Supplement or otherwise) shall have been complied with to the reasonable satisfaction of the Placement Agent. Any filings required to be made by the Company in accordance with Section 4(a) shall have been timely filed with the Commission.

(b) The Placement Agent shall not have discovered and disclosed to the Company on or prior to the Closing Date that the Registration Statement, the Base Prospectus or the Prospectus Supplement or any amendment or supplement thereto contains an untrue statement of a fact which, in the opinion of counsel for the Placement Agent, is material or omits to state any fact which, in the opinion of such counsel, is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(c) All corporate proceedings and other legal matters incident to the authorization, form and validity of each of the Transaction Documents, the Stock, the Registration Statement, the Base Prospectus and the Prospectus Supplement and all other legal matters relating to the Transaction Documents and the transactions contemplated hereby shall be reasonably satisfactory in all material respects to counsel for the Placement Agent, and the Company shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

(d) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP shall have furnished to the Placement Agent, such counsel’s written opinion, as counsel for the Company, addressed to the Placement Agent and the Purchasers and dated the Closing Date in form and substance reasonably satisfactory to the Placement Agent, to the effect that, subject to customary qualifications and assumptions:

(i) the Company is validly existing as a corporation in good standing under the laws of the state of Delaware, is duly qualified to do business and is in good standing as a foreign corporation in all jurisdictions in which the character of the property owned or leased or the nature of the business transacted by it makes qualification necessary, and has all corporate authority necessary to own or hold its properties and to conduct the business in which it is engaged as described in the Base Prospectus and the Prospectus Supplement, except where the failure to so qualify or have such authority, singularly or in the aggregate, could not reasonably be expected to have a Material Adverse Effect;

(ii) the Company has the authorized capitalization as set forth in the Base Prospectus as supplemented by the Prospectus Supplement, and the Stock when issued and delivered to and paid for by the purchasers thereof as contemplated by this Agreement, will be duly and validly authorized and issued, fully paid and non-assessable and will conform to the description thereof contained in the Base Prospectus as supplemented by the Prospectus Supplement;

(iii) other than such rights as have been waived by the holders thereof, there are no preemptive or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any shares of the Stock pursuant to the Company’s Certificate of

Incorporation, Certificate of Designations or bylaws or any agreement or other instrument known to such counsel;

(iv) the Transaction Documents have been duly authorized, executed and delivered by the Company;

(v) the execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby will not result in any violation of the provisions of the Certificate of Incorporation, Certificate of Designations or bylaws of the Company or, to the knowledge of such counsel, any judgment, order or decree of any court or governmental agency or body having jurisdiction over the Company or any of its properties or assets;

(vi) the Registration Statement was declared effective under the Securities Act as of the date and time specified in such opinion, the Prospectus Supplement was filed with the Commission pursuant to the subparagraph of Rule 424(b) of the Rules and Regulations specified in such opinion on the date specified therein and no stop order suspending the effectiveness of the Registration Statement has been issued and, to the knowledge of such counsel, no proceeding for that purpose is pending or threatened by the Commission;

(vii) except for the registration of the Stock under the Securities Act and such consents, approvals, authorizations, registrations or qualifications as may be required under the Exchange Act and applicable state securities laws in connection with the purchase and distribution of the Stock, no consent, approval, authorization or order of, or filing or registration with, any court, governmental agency or governmental body is required for the execution, delivery and performance of this Agreement by the Company and the consummation by the Company of the transactions contemplated hereby;

(viii) to such counsel’s knowledge, no person or entity has the right to require registration of shares of Common Stock or other securities of the Company because of the filing or effectiveness of the Registration Statement, the completion of the Offering or otherwise, except for persons and entities who have expressly waived such right or who have been given proper notice and have failed to exercise such right within the time or times required under the terms and conditions of such right;

(ix) the statements in the Base Prospectus and the Prospectus Supplement (other than the financial statements and related schedules and other financial and statistical data contained therein, as to which such counsel need express no opinion) under the headings “Who We Are,” “Risk Factors,” “Description of Capital Stock” and “Plan of Distribution,” Item 15 of Part II of the Registration Statement, and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2002 under Item 1, “Business,” to the extent that they constitute summaries of matters of law or regulation or legal conclusions, have been reviewed by such counsel and fairly summarize the matters described therein in all material respects; and

(x) to such counsel’s knowledge and other than as set forth in the Base Prospectus and the Prospectus Supplement, there are no legal or governmental proceedings pending to which the Company is a party or of which any property or asset of the Company is the subject which, singularly or in the aggregate, if determined adversely to the Company, would prevent or adversely affect the ability of the Company to perform its obligations under this Agreement; and, to such counsel’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

In addition, such counsel shall state that it has participated in conferences with officers and other representatives of the Company, at which conferences such counsel made inquiries of such persons and others and discussed the contents of the Registration Statement and the Prospectus Supplement. Such counsel shall also state that while the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such that such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus Supplement, subject to the foregoing and on the basis of such participation, inquiries and discussions, no facts have come to the attention of such counsel which have caused it to believe that either the Registration Statement or any amendments thereto, at the time the Registration Statement or any such amendments became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus Supplement, as of the Closing, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (it being understood that such counsel need express no belief as to the financial statements, including the notes and schedules thereto, or any other financial information, or the information regarding the Placement Agent or the method of distribution of the Stock included in the Registration Statement or the Prospectus Supplement).

(e) The Company shall have furnished to the Placement Agent and the Purchasers a certificate, dated the Closing Date, executed by its Chairman and Chief Executive Officer and its Chief Financial Officer stating that (i) such officers have examined the Registration Statement, the Base Prospectus and the Prospectus Supplement and, in their opinion, the Registration Statement as of its effective date and the Prospectus Supplement (taken together with the Base Prospectus), as of the date of the Prospectus Supplement and the date of such certificate, did not include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of the Prospectus Supplement, taken together with the Base Prospectus, in light of the circumstances in which such statements were made), (ii) since the effective date of the Registration Statement no event has occurred which should have been set forth in a supplement or amendment to the Registration Statement, the Base Prospectus or the Prospectus Supplement and which has not been so set forth, (iii) to their knowledge after reasonable investigation, as of the Closing Date, the representations and warranties of the Company in this Agreement are true and correct and the

Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date, and (iv) subsequent to the date of the most recent financial statements included or incorporated by reference in the Base Prospectus and the Prospectus Supplement, there has been no material adverse change in the financial position or results of operation of the Company, or any change, or any development including a prospective change, in or affecting the condition (financial or otherwise), results of operations, business or prospects of the Company, except as set forth in the Base Prospectus and the Prospectus Supplement.

(f) At the time of the execution of this Agreement, the Placement Agent shall have received from KPMG LLP a draft of a letter, addressed to the Placement Agent and the Purchasers and dated such date, in form and substance reasonably satisfactory to the Placement Agent (i) confirming that they are independent certified public accountants with respect to the Company within the meaning of the Securities Act and the Rules and Regulations and (ii) stating the conclusions and findings of such firm with respect to the financial statements and certain financial information contained or incorporated by reference in the Base Prospectus and the Prospectus Supplement (the “Comfort Letter”).

(g) On the Closing Date, the Placement Agent shall have received the Comfort Letter duly executed by KPMG LLP addressed to the Placement Agent and dated the Closing Date.

(h) (i) The Company shall not have sustained since the date of the latest audited financial statements included or incorporated by reference in the Base Prospectus and the Prospectus Supplement any loss or interference with its business from fire, explosion, flood, terrorist act or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth in or contemplated by the Base Prospectus and the Prospectus Supplement, and (ii) since such date there shall not have been any change in the capital stock or long-term debt of the Company or any change, or any development involving a prospective change, in or affecting the business, general affairs, management, financial position, stockholders’ equity, results of operations or prospects of the Company, otherwise than as set forth in or contemplated by the Base Prospectus and the Prospectus Supplement, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Placement Agent, so material and adverse as to make it impracticable or inadvisable to proceed with the sale or delivery of the Stock on the terms and in the manner contemplated by the Base Prospectus and the Prospectus Supplement.

(i) No issues shall have been raised by the Nasdaq Stock Market with respect to the Notification Form for Listing of Additional Shares filed pursuant to 2(z) which remain unresolved.

(j) At the time of execution of this Agreement, the Company shall have furnished to the Placement Agent a letter substantially in the form of Exhibit D hereto from each executive officer and director of the Company listed on Exhibit C hereto.

(l) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental agency or body which would, as of the Closing Date, prevent the issuance or sale of the Stock; and no injunction, restraining order or order of any other nature by any federal or state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Stock.

(m) The Company shall have prepared and filed with the Commission a Current Report on Form 8-K with respect to the Offering, including as an exhibit thereto this Agreement and any other documents relating thereto.

7. Indemnification and Contribution.

(a) The Company shall indemnify and hold harmless the Placement Agent, its officers, employees, representatives and agents and each person, if any, who controls the Placement Agent within the meaning of the Securities Act (collectively the “Placement Agent Indemnified Parties” and each a “Placement Agent Indemnified Party”) against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which that Placement Agent Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Registration Statement or the Prospectus Supplement or in any amendment or supplement thereto, (ii) the omission or alleged omission to state in the Base Prospectus, the Registration Statement or the Prospectus Supplement or in any amendment or supplement thereto a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any act or failure to act, or any alleged act or failure to act, by the Placement Agent in connection with, or relating in any manner to, the Stock or the Offering contemplated hereby; (provided that the Company shall not be liable in the case of any matter covered by this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such act or failure to act undertaken or omitted to be taken by such Placement Agent through its gross negligence or willful misconduct) and shall reimburse each Placement Agent Indemnified Party promptly upon demand for any legal or other expenses reasonably incurred by that Placement Agent Indemnified Party in connection with investigating or preparing to defend or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from the Base Prospectus, the Registration Statement or the Prospectus Supplement or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company through the Placement Agent specifically for use therein, which information the parties hereto agree is limited to the Placement Agent’s Information (as defined in Section 15). This indemnity agreement is not exclusive and will be in addition to any liability, which the Company might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to each Placement Agent Indemnified Party.

(b) The Placement Agent shall indemnify and hold harmless the Company, its officers, employees, representatives and agents, each of its directors and each person, if any, who controls the Company within the meaning of the Securities Act (collectively the “Company Indemnified Parties” and each a “Company Indemnified Party”) against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company Indemnified Parties may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Base Prospectus, the Registration Statement or the Prospectus Supplement or in any amendment or supplement thereto, or (ii) 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, but with respect to each of clause (i) and this clause (ii) only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company through the Placement Agent specifically for use therein, and shall reimburse the Company Indemnified Parties promptly upon demand for any legal or other expenses reasonably incurred by such parties in connection with investigating or preparing to defend or defending against or appearing as third party witness in connection with any such loss, claim, damage, liability or action as such expenses are incurred; provided that the parties hereto hereby agree that such written information provided by the Placement Agent consists solely of the Placement Agent’s Information. This indemnity agreement is not exclusive and will be in addition to any liability, which the Placement Agent and the Purchasers might otherwise have and shall not limit any rights or remedies which may otherwise be available at law or in equity to the Company Indemnified Parties. Notwithstanding the provisions of this Section 7(b), in no event shall any indemnity under this Section 7(b) exceed the total compensation received by the Placement Agent in accordance with Section 1(f).

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure; and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized by the indemnifying party in writing, (ii) such indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ separate counsel or (iii) the indemnifying party has failed to assume the defense of such action in a reasonably prompt manner and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the

indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties, which firm shall be designated in writing by the Placement Agent, if the indemnified parties under this Section 7 consist of any Placement Agent Indemnified Party, or by the Company if the indemnified parties under this Section 7 consist of any Company Indemnified Parties. Each indemnified party, as a condition of the indemnity agreements contained in Sections 7(a) and 7(b) shall use all reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. Subject to the provisions of Section 7(d) below, no indemnifying party shall be liable for any settlement, compromise or the consent to the entry of judgment in connection with any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action other than a judgment entered with the consent of such indemnified party, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for reasonable fees and actual out-of-pocket expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by this Section 7 effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other from the offering of the Stock or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Placement Agent on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agent on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company bears to the total compensation received by the Placement

Agent with respect to the Stock purchased under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Placement Agent on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission; provided that the parties hereto agree that the written information furnished to the Company by the Placement Agent for use in the Prospectus Supplement consists solely of the Placement Agent’s Information. The Company and the Placement Agent agree that it would not be just and equitable if contributions pursuant to this Section 7(e) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7(e) shall be deemed to include, for purposes of this Section 7(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(e), the Placement Agent shall not be required to contribute any amount in excess of the amount by which the total price at which the Stock was offered and sold to the public less the amount of any damages which such Placement Agent has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission.

Schedule 2(n)

▇▇▇▇▇▇▇▇▇▇ County (Pennsylvania) Industrial Development Authority Bonds

In 1997, we issued, through the ▇▇▇▇▇▇▇▇▇▇ County (Pennsylvania) Industrial Development Authority, $9.4 million of taxable and tax-exempt bonds. The bonds are supported by an AA-rated letter of credit, and a reimbursement agreement between our bank and the letter of credit issuer. The interest rate on the bonds will vary weekly, depending on market rates for AA-rated taxable and tax-exempt obligations, respectively.

The terms of the bond issuance provide for monthly, interest-only payments and a single repayment of principal at the end of the twenty-year life of the bonds. However, under our agreement with our bank, we are making monthly payments to an escrow account to provide for an annual prepayment of principal.

To provide credit support for this arrangement, we have given a first mortgage on land, building, improvements, and certain machinery and equipment to our bank. We have also agreed to maintain a minimum required cash and short-term investments balance of at least two times the current loan balance. If we fail to comply with this covenant, we are required to deposit with the lender cash collateral up to, but not more than, the unpaid balance of the loan, which was $3.9 million as of June 30, 2003.

Equipment Loans

In September 2003, we borrowed $831,000 to finance the purchase of equipment and facility improvements. The equipment and facility improvements are collateralizing the amount borrowed. The terms of the financing require us to pay monthly principal and interest payments for the equipment financing over 48 months at an interest rate of 8.35%.

In March 2003, we borrowed $2,954,000 to finance the purchase of equipment, which is collateralizing the amount borrowed. The terms of the financing require us to pay monthly principal and interest payments over 42 months at an interest rate of 8.35%. During 2004, we will be required to make payments totaling $976,000 under this agreement.

In December 2002, we borrowed approximately $2,261,000 to finance the purchase of equipment, which is collateralizing the amount borrowed. The terms of the financing require us to pay monthly principal and interest payments over 36 months at an interest rate of 8.0%. During 2004, we will be required to make payments totaling $850,000 under this agreement.

Capital Lease Obligations

In June 2003, we entered into a capital lease to lease $119,000 of equipment. The terms of the lease required us to make an initial payment of $31,000 followed by monthly payments through June 2006. During 2004, we will be required to make payments totaling $37,000 under this agreement.

In April and May 2003, we entered into capital leases to lease $254,000 of equipment. The terms of the leases require us to make monthly payments through April 2006. During 2004, we will be required to make payments totaling $96,000 under these agreements.

In November 2002, we entered into a capital lease to lease $50,000 of equipment. The terms of the lease require us to make monthly payments of $1,561 over 36 months. During 2004, we will be required to make payments totaling $19,000 under this agreement.

(b) In the event that (i) the Shares have been subscribed for and funds in respect thereof shall have been deposited with the Escrow Agent on or before the Termination Date and (ii) no Offering Termination Notice shall have been delivered to the Escrow Agent, the Company and the Placement Agent shall deliver to the Escrow Agent a joint notice, not less than one (1) nor more than three (3) business days prior to the Closing Date, substantially in the form

The Escrow Agent, after receipt of such Closing Notice, on such Closing Date, shall pay to the Company and the Placement Agent, in federal or other immediately available funds and otherwise in the manner specified by the Company in such Closing Notice, an amount equal to the aggregate of the subscription amounts paid by the subscribers identified in such Closing Notice for the Shares to be sold on such Closing Date as set forth on the list held by the Escrow Agent pursuant to Section 3.

(c) If at any time and from time to time prior to the release of any subscriber’s total subscription amount pursuant to paragraph (a) or (b) of this Section 4 from escrow, the Company shall deliver to the Escrow Agent a notice, substantially in the form of Exhibit D hereto (a “Subscription Termination Notice”), to the effect that any or all of the subscriptions of such subscriber have been rejected by the Company (a “Rejected Subscription”), the Escrow Agent, promptly after receipt of such Subscription Termination Notice and, if such subscriber delivered a check in payment of its Rejected Subscription, after the clearance of such check, to the extent of the sum of such subscriber’s Rejected Subscription amount as set forth in the Subscription Termination Notice, send to such subscriber, in the manner set forth in paragraph (d) of this Section 4, a check to the order of such subscriber in the amount of such Rejected Subscription amount.

(d) For the purposes of this Section 4, any check that the Escrow Agent shall be required to send to any subscriber shall be sent to such subscriber by first class mail, postage prepaid, at such subscriber’s address furnished to the Escrow Agent pursuant to Section 3.

5. Escrow Agent; Duties and Liabilities.

(a) It is expressly understood and agreed by the parties that (i) the duties of the Escrow Agent, as herein specifically provided, are purely ministerial in nature; (ii) the Escrow Agent shall not have any duty to deposit the Escrowed Funds except as provided herein, (iii) the Escrow Agent shall not be responsible or liable in any manner whatsoever for, or have any duty to inquire into, the sufficiency, correctness, genuineness or validity of the notices it receives hereunder, or the identity, authority or rights of any of the parties; (iv) the Escrow Agent shall have no duties or responsibilities in connection with the Escrowed Funds, other than those specifically set forth in this Agreement; (v) the Escrow Agent shall not incur any liability in acting upon any signature, written notice, request, waiver, consent, receipt, or any other paper or document believed by the Escrow Agent to be genuine; (vi) the Escrow Agent may assume that any person purporting to have authority to give notices on behalf of any of the parties in accordance with the provisions hereof has been duly authorized to do so; (vii) the Escrow Agent shall incur no liability whatsoever except for such resulting from its willful misconduct or gross negligence, as long as the Escrow Agent has acted in good faith in the performance of its duties hereunder; and (viii) upon the Escrow Agent’s performance of its obligations under Section 4 hereof, the Escrow Agent shall be relieved of all liability, responsibility and obligation with respect to the Escrowed Funds or arising out of or under this Agreement.

(b) The Escrow Agent shall not be under any obligation to take any legal action in connection with this Agreement or towards its enforcement or performance, or to appear in, prosecute or defend any action or legal proceeding, or to file any return, or pay or withhold any income or other tax payable with respect to any Escrowed Funds or the disbursement thereof, any payment of or in respect of which shall constitute a Loss under Section 6 below, and Placement Agent and the Company agree to provide to the Escrow Agent such information and documentation as the Escrow Agent may reasonably request in connection therewith.

(c) In the event of any disagreement relating to the Escrowed Funds or the disbursement thereof resulting in adverse claims or demands being made in connection with the Escrowed Funds or in the event that the Escrow Agent is in doubt as to what action it should take hereunder, the Escrow Agent shall be entitled to retain the Escrowed Funds, but only to the extent of the Escrowed Funds in controversy, until the Escrow Agent shall have received a final non-appealable order of a court of competent jurisdiction directing delivery of the Escrowed Funds, in which event the Escrow Agent shall disburse the Escrowed Funds in accordance with such order. Any court order shall be accompanied by a legal opinion by counsel for the presenting party satisfactory to the Escrow Agent to the effect that the order is final and non-appealable. The Escrow Agent shall act on such court order and legal opinion without further question. If a proceeding for such determination is not begun and diligently continued, the Escrow Agent may make an ex parte application, or bring any appropriate action, for leave to deposit the Escrowed Funds in the Supreme Court of the State of New York, County of New York seeking such determination or such declaratory relief as the Escrow Agent shall deem reasonably necessary under the circumstances, and the parties each hereby irrevocably consent to the entering of an ex parte order pursuant to all applicable laws, rules and procedures of the State of New York and such court. The Escrow Agent shall be reimbursed by the Company, for all of the Escrow Agent’s reasonable costs and expenses of such action or proceeding, including, without limitation, attorneys’ fees and disbursements.

(d) The Escrow Agent does not have any interest in the Escrowed Funds deposited hereunder and is serving as escrow agent only and having only possession thereof. Any payments of income from the Escrowed Funds shall be subject to withholding regulations then in force with respect to United States federal or state income taxes. The parties hereto shall provide the Escrow Agent with appropriate Internal Revenue Service Forms W-9 for tax identification number certification, or non-resident alien certifications. Section 5(c) and this Section 5(d) shall survive any termination of this Agreement or the resignation of the Escrow Agent in accordance with Section 5(h) below.

(e) None of the provisions of this Agreement shall require the Escrow Agent to expend or risk its own funds or otherwise to incur any liability, financial or otherwise, in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it.

(f) The Escrow Agent may consult with independent counsel and the advice or any opinion of counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or opinion of counsel.

(g) The Escrow Agent may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or through agents, attorneys, custodians or nominees appointed with due care, and shall not be responsible for any willful misconduct or gross negligence on the part of any agent, attorney, custodian or nominee so appointed.

(h) The Escrow Agent may at any time resign by giving ten (10) days written notice of resignation to the Company and the Placement Agent. Upon receiving such notice of resignation, the Company and the Placement Agent shall promptly appoint a successor and, upon the acceptance by the successor of such appointment, release the resigning Escrow Agent from its obligations hereunder by written instrument, a copy of which instrument shall be delivered to the resigning Escrow Agent and the successor. If no successor shall have been so appointed and have accepted appointment within forty-five (45) days after the giving of such notice of resignation, the resigning Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor.

(i) Any partnership or other similar entity into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any partnership, corporation or other similar entity resulting from any merger, conversion or consolidation to which the Escrow Agent shall be a party, or any partnership, corporation or other similar entity succeeding to the business of the Escrow Agent shall be the successor of the Escrow Agent hereunder without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto except where an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding.

(j) No printed or other matter in any language (including, without limitation, the Registration Statement, the prospectus and prospectus supplement relating to the Registration Statement, notices, reports and promotional material) which mentions the Escrow Agent’s name or the rights, powers, or duties of the Escrow Agent shall be issued by the other parties hereto or on such parties’ behalf unless the Escrow Agent shall first have given its specific written consent thereto. The Escrow Agent hereby consents to the use of its name and the reference to the escrow arrangement in the Registration Statement and in the prospectus.

6. Indemnification of Escrow Agent. The Company and the Placement Agent hereby agree to indemnify and hold the Escrow Agent harmless from any and all liabilities, obligations, damages, losses, claims, encumbrances, costs or expenses (including reasonable attorneys’ fees and expenses) (any or all of the foregoing herein referred to as a “Loss”) arising hereunder or under or with respect to the Escrowed Funds, except for Losses resulting from the willful misconduct or gross negligence of the Escrow Agent. Anything in this agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits),

even if the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

7. Fees. The Company agrees to (a) pay the Escrow Agent upon execution of this Agreement and from time to time thereafter reasonable compensation for the services to be rendered hereunder, which unless otherwise agreed in writing shall be as described in Schedule 1 attached hereto, and (b) pay or reimburse the Escrow Agent upon request for all expenses, disbursements and advances, including reasonable attorney’s fees and expenses, incurred or made by it in connection with the preparation, execution, performance, delivery, modification and termination of this Agreement.

8. Security Procedures. In the event funds transfer instructions are given (other than in writing at the time of execution of this Agreement, as indicated in Schedule 2 attached hereto), whether in writing, by telecopier or otherwise, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call-back to the person or persons designated on Schedule 3 hereto, and the Escrow Agent may rely upon the confirmation of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed only in a writing actually received and acknowledged by the Escrow Agent. If the Escrow Agent is unable to contact any of the authorized representatives identified in Schedule 3, the Escrow Agent is hereby authorized to seek confirmation of such instructions by telephone call-back to any one or more of your executive officers (“Executive Officers”), as the Escrow Agent may select. Such Executive Officer shall deliver to the Escrow Agent a fully executed Incumbency Certificate, and the Escrow Agent may rely upon the confirmation of anyone purporting to be any such officer. The Escrow Agent and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar identifying numbers provided by the Company or the Placement Agent to identify (a) the beneficiary, (b) the beneficiary’s bank, or (c) an intermediary bank. The Escrow Agent may apply any of the escrowed funds for any payment order it executes using any such identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated. The parties to this Agreement acknowledge that these security procedures are commercially reasonable.

Dear Sir or Madam:

The undersigned understands that you, as Placement Agent, propose to enter into a Placement Agent Agreement (the “Placement Agent Agreement”) with Neose Technologies, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) of shares of Common Stock of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Placement Agent Agreement.

In consideration of the foregoing, and in order to induce you to act as Placement Agent in the offering, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of ▇.▇. ▇▇▇▇▇▇ Securities Inc., the undersigned will not, during the period beginning on the date hereof and ending on the date 90 days after the date of the final prospectus supplement relating to the Offering of the Securities, (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. In addition, the undersigned agrees that, without the prior written consent of ▇.▇. ▇▇▇▇▇▇ Securities Inc., it will not, during the period beginning on the date hereof and ending on the date 90 days after the date of the final prospectus supplement relating to the Offering of the Securities, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.

Notwithstanding the foregoing, the restrictions set forth in clause (1) and (2) above shall not apply to (a) transfers (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) with the prior written consent of ▇.▇. ▇▇▇▇▇▇ Securities Inc., (iv) effected pursuant to any exchange of “underwater”

options with the Company, or (v) in connection with a Sale of the Company, or (b) the acquisition or exercise of any stock option issued pursuant to the Company’s existing stock option plan, including any exercise effected by the delivery of Securities of the Company held by the undersigned. For purposes of this Letter Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if the Placement Agent Agreement does not become effective, or if the Placement Agent Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, the undersigned shall be released form all obligations under this Letter Agreement.

This Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Very truly yours,
