There is no action, suit or proceeding, or governmental inquiry or investigation, pending, or, to the best of the Company's knowledge, any basis therefor or threat thereof, against the Company or any Subsidiary, which questions the validity or legality of this Agreement or the right of the Company to enter into any such agreement, or which might result, either individually or in the aggregate, in a Company Material Adverse Effect, nor is there any litigation pending, or, to the best of the Company's knowledge, any basis therefor or threat thereof, against the Company or any Subsidiary by reason of the past or present employment relationships of any of the Company's or any Subsidiary's employees, the past, current or proposed activities of the Company or any Subsidiary, or negotiations by the Company with possible investors in the Company. Neither the Company nor any Subsidiary is subject to any outstanding judgment, order or decree. 3.9 Financial Statements; Liquidity. (a) The Company has furnished to the Purchaser a complete and correct copy of the audited balance sheet of the Company at December 31, 2001 and December 31, 2002 and 5 the related audited statements of operations and cash flows for the respective fiscal years then ended (collectively, the "Financial Statements"). The Financial Statements are complete and correct, are in accordance with the books and records of the Company and present fairly the financial condition and results of operations of the Company at the dates and for the periods indicated, and have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") consistently applied. (b) The Company reasonably believes that it has the financial resources, without giving effect to the proceeds of the Celgene note and the Note hereunder, to conduct the business of the Company and its Subsidiaries, as presently conducted and as proposed to be conducted, during the twelve-month period ending March 31, 2004. 3.10 Absence of Undisclosed Liabilities. Neither the Company nor any Subsidiary has any liability (whether known or unknown and whether absolute or contingent), except for contractual liabilities incurred in the ordinary course of business which are not required by GAAP to be reflected on a balance sheet and which contractual liabilities would not, either individually or in the aggregate, result in a Company Material Adverse Effect. 3.11 Taxes. The amount shown on the Financial Statements as provision for taxes is sufficient in all material respects for payment of all accrued and unpaid federal, state, county, local and foreign taxes for the period then ended and all prior periods and any other taxes payable by the Company howsoever arising. The Company has filed or has obtained presently effective extensions with respect to all federal, state, county, local and foreign tax returns which are required to be filed by it, such returns are true and correct and all taxes shown thereon to be due have been timely paid with exceptions not material to the Company. Federal income tax returns of the Company have not been audited by the Internal Revenue Service, and no controversy with respect to taxes of any type is pending or, to the best of the Company's knowledge, threatened. The Company has withheld or collected from each payment made to its employees the amount of all taxes required to be withheld or collected therefrom and has paid all such amounts to the appropriate taxing authorities when due. Neither the Company nor any of its stockholders (with respect to the Company) has ever filed (a) an election pursuant to Section 1362 of the Internal Revenue Code of 1986, as amended (the "Code"), that the Company be taxed as an S Corporation or (b) a consent pursuant to Section 341(f) of the Code relating to collapsible corporations. To the best of the Company's knowledge, without inquiring as to any direct or indirect changes in the ownership structure of stockholders of the Company that are investment funds, the Company's net operating losses for federal income tax purposes, as set forth in the Financial Statements, are not subject to any limitations imposed by Section 382 of the Code, and consummation of the transactions contemplated by this Agreement or by any other agreement, understanding or commitment, contingent or otherwise, to which the Company is a party or by which it is otherwise bound will not have the effect of limiting the Company's ability to use such net operating losses in full to offset such taxable income. 3.12 Property and Assets. The Company and each Subsidiary has good title to, or a valid leasehold interest in, all of its material properties and assets, and none of such properties or assets is subject to any Security 6 Interest other than those the material terms of which are described in the Company Disclosure Schedule. 3.13 Intellectual Property. (a) The Company and each Subsidiary owns, free and clear of all Security Interests, or has the valid right to use, all Intellectual Property (as defined below in this Section 3.13) used by it in its business as currently conducted or as currently proposed to be conducted. No other person or entity (other than licensors of software that is generally commercially available on reasonable terms, licensors of Intellectual Property under the agreements disclosed pursuant to paragraph (d) below and non-exclusive licensees of the Company's Intellectual Property in the ordinary course of the Company's business) has any rights to any of the Intellectual Property owned or used by the Company and, to the best of the Company's knowledge, no other person or entity is infringing, violating or misappropriating any of the Intellectual Property that the Company owns or to which it has obtained exclusive licenses. For purposes of this Agreement, "Intellectual Property" means all (i) United States and foreign patents and patent applications, and any divisional, continuation, continuation in part, reissue, renewal or re-examination patent issuing therefrom (including any foreign counterparts), (ii) copyrights and registrations thereof, (iii) mask works and registrations and applications for registration thereof, (iv) computer software, including any and all software implementations of algorithms, models and methodologies, whether in source code or object code, (v) databases and compilations, including any and all data and collections of data, whether machine readable or otherwise, (vi) technology supporting any Internet site(s) operated by or on behalf of the Company, (vii) trade secrets and other confidential business information, whether patentable or unpatentable and whether or not reduced to practice, know-how, technology, proprietary processes, techniques, methodologies, formulae, algorithms, models, user interfaces, research and development information, copyrightable works, financial, marketing and business data, pricing and cost information, business and marketing plans and customer and supplier lists and information, inventions, source code, object code, and, with respect to all of the foregoing, related confidential documentation, (viii) trademarks, service marks, trade names, domain names and applications and registrations therefor, (ix) all documentation, including user manuals and training materials relating to any of the foregoing and descriptions, flow-charts and other work product used to design, plan, organize and develop any of the foregoing, and (x) other proprietary rights relating to any of the foregoing. (b) To the best of the Company's knowledge, none of the activities or business conducted by the Company or any Subsidiary infringes, violates or constitutes a misappropriation of (or in the past infringed, violated or constituted a misappropriation of) any Intellectual Property of any other person or entity and none of the activities or business presently proposed to be conducted will infringe, violate or constitute a misappropriation of any Intellectual Property, in existence on the date of this Agreement, of any other person or entity. Neither the Company nor any Subsidiary has received any complaint, claim or notice alleging any such infringement, violation or misappropriation, and to the knowledge of the Company, there is no basis for any such complaint, claim or notice. (c) Section 3.13(c) of the Company Disclosure Schedule identifies with respect to the Company and each Subsidiary each (i) patent that has been issued or assigned to it 7 with respect to any of its Intellectual Property, (ii) pending patent application that it has made with respect to any of its Intellectual Property, (iii) copyright, trademark or service mark registration or application with respect to its Intellectual Property, (iv) domain name registration or application with respect to its Intellectual Property and (v) mask work registration or application with respect to its Intellectual Property. (d) Section 3.13(d) of the Company Disclosure Schedule hereto identifies each agreement (other than employee and consultant agreements concerning assignment of inventions) with a third party pursuant to which the Company or any Subsidiary obtains rights to Intellectual Property material to the business of the Company or any such Subsidiary as currently conducted or as currently proposed to be conducted (other than software that is generally commercially available on reasonable terms) that is owned by a party other than the Company or any Subsidiary. Except as set forth on Section 3.13(d) of the Company Disclosure Schedule, other than license fees for software that is generally commercially available on reasonable terms, neither the Company nor any Subsidiary is obligated to pay any royalties or other compensation to any third party in respect of its ownership, use or license of any of its Intellectual Property. (e) The Company and each Subsidiary has taken and shall take all reasonable precautions and actions (i) to protect its rights in its Intellectual Property and (ii) to maintain the confidentiality of its trade secrets, know-how and other confidential Intellectual Property. To the best of the Company's knowledge, there have been no acts or omissions by the officers, directors, shareholders, employees, independent contractors or other agents of the Company or any Subsidiary, which could materially compromise the rights of the Company or any Subsidiary in its Intellectual Property, including without limitation the Company's or any Subsidiary's ability to apply for or enforce appropriate legal protection of its Intellectual Property. (f) All of the Company's and each Subsidiary's Intellectual Property has been created by employees of the Company or such Subsidiary within the scope of their employment by the Company or such Subsidiary or by independent contractors of the Company or such Subsidiary, each of whom has executed agreements expressly assigning all right, title and interest in such Intellectual Property to the Company or such Subsidiary. No portion of the Company's or any Subsidiary's Intellectual Property was jointly developed with any third party. To the best of the Company's knowledge, no other person or entity (including without limitation any prior employer of any employee of the Company or any Subsidiary) has any right to, or interest in, any of the Intellectual Property that is material to the business of the Company or such Subsidiary as currently conducted or as currently proposed to be conducted (other than software that is generally commercially available on reasonable terms). 3.14 Insurance. Each of the Company and each Subsidiary maintains valid policies of workers' compensation insurance and of insurance with respect to its properties and business of the kinds and in the amounts not less than is customarily obtained by corporations of established reputation engaged in the same or similar business and similarly situated, including, without limitation, insurance against loss, damage, fire, theft, public liability and other risks, as well as directors and officers liability insurance. 3.15 Material Contracts and Obligations. Section 3.15 of the Company Disclosure Schedule sets forth a list of all material agreements or commitments of any nature 8 (whether written or oral) to which the Company and each Subsidiary is a party or by which it is bound, including without limitation (a) any agreement which requires future expenditures by the Company or any Subsidiary in excess of $50,000 or which might result in payments to the Company or any Subsidiary in excess of $50,000, (b) any employment or consulting agreement, employee benefit, bonus, pension, profit-sharing, stock option, stock purchase or similar plan or arrangement, (c) any distributor, sales representative or similar agreement, (d) any agreement with any current or former stockholder, officer or director of the Company or any Subsidiary, or any "affiliate" or "associate" of such persons (as such terms are defined in the rules and regulations promulgated under the Securities Act), including without limitation any agreement or other arrangement providing for the furnishing of services by, rental of real or personal property from, or otherwise requiring payments to, any such person or entity, (e) any agreement under which the Company or any Subsidiary is restricted from carrying on any business anywhere in the world, (f) any agreement relating to indebtedness for borrowed money or the extension of credit, whether or not currently funded, (g) any agreement for the disposition of a material portion of the Company's or any Subsidiary's assets (other than for the sale of inventory in the ordinary course of business) and (h) any agreement for the acquisition of the business or securities or other ownership interests of another party, whether such acquisition is completed or pending. Each such agreement or contract is valid, binding and in full force and effect. Neither the Company, nor, to the best of the Company's knowledge, any other party thereto, is in default of any of its obligations under any agreement or contract listed on the Company Disclosure Schedule, except for defaults that would not have a Company Material Adverse Effect. 3.16 Compliance. Each of the Company and each Subsidiary has, in all material respects, complied with all laws, regulations, orders and all industry accepted prescription safety standards applicable to its present and proposed business except where the failure to so comply would not have a Company Material Adverse Effect and has all approvals, permits and licenses required to operate its business in the manner presently operated, except for defaults that would not have a Company Material Adverse Effect. To the best of the Company's knowledge, no material expenditures will be required in order to comply with any existing statute, law or regulation. There is no term or provision of any mortgage, indenture, contract, agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound, or, to the best of the Company's knowledge, of any provision of any state or federal judgment, decree, order, statute, rule or regulation applicable to or binding upon the Company or any Subsidiary, which materially adversely affects or, so far as the Company may now foresee, in the future is reasonably likely to result in or have a Company Material Adverse Effect. To the best of the Company's knowledge, no employee of the Company is in violation of any material term of any contract or covenant (either with the Company, a Subsidiary or with another entity) relating to employment, patents, assignment of inventions, proprietary information disclosure, non-competition or non-solicitation. 3.17 Absence of Changes.

The Company has delivered copies of any such agreements to the Purchasers. To the knowledge of the Company, no employee of the Company or any Subsidiary is obligated under any contract (including any license, covenant or commitment of any nature) or subject to any judgment, decrees or administrative agency of which the Company has knowledge, that would conflict or interfere with (i) the performance of the employee's duties as an employee, director or officer of the Company or each Subsidiary, or (ii) the Company's or any such Subsidiary's business as conducted or proposed to be conducted. 3.19 ERISA.

The Company has filed with the Internal Revenue Service all statements, if any, with its U.S. income tax returns, which are required under Treasury Regulation Section 1.897-2(h). 3.24 No Preemptive Rights or Rights of First Refusal. The sale of the Securities is not, and the subsequent conversion or exercise of the Securities into Common Stock will not be, subject to any preemptive rights or rights of first refusal that have not been properly waived or complied with. 3.25 Related-Party Transactions. (a) No employee, consultant, officer, shareholder, director or affiliate (as defined in the rules and regulations promulgated under the Securities Act) of the Company, or, in the case of any of the foregoing who are individuals, any member of his or her immediate family, or any affiliate of any of the foregoing, is indebted to, or owns an interest in the property, technology or licenses of, the Company.

Neither this Agreement nor any Exhibit or Schedule hereto, nor any report, certificate, document or instrument furnished to the Purchaser or its agents in connection with the transactions contemplated by this Agreement, when read together, contains or will contain any untrue statement of a material fact or omits or will omit to state a material fact necessary in order to make the statements contained herein or therein, in light of the circumstances under which they were made, not misleading. 12 3.27 Comparability to Celgene Agreement. The provisions of this Agreement and the transactions contemplated hereby, including without limitation its representations, warranties and covenants, are in all material respects identical to those contained in that certain securities purchase agreement, dated April 8, 2003 (the "Celgene Agreement"), by and among the Company and Celgene Corporation ("Celgene"), with the following exceptions: (a) Celgene is providing $12,000,000 of funding instead of $2,000,000, and the warrant to be issued to Celgene (the "Celgene Warrant") is proportionally larger than the Warrant; and (b) the note to be issued to Celgene (the "Celgene Note") is a Senior Convertible Note, while the Note issued under this Agreement is expressly subordinated to the Celgene Note. No changes to the Celgene Note or Celgene Warrant have been proposed or are currently contemplated by the Company. 4. Representations of the Purchaser. The Purchaser represents and warrants to the Company as follows: 4.1 Investment. The Purchaser is acquiring the Securities, and the shares of Common Stock into which the Securities may be converted or exchanged, for the Purchaser's own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and, except as contemplated by this Agreement and the Exhibits hereto, the Purchaser has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof. The Purchaser is an "accredited investor" as that term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act. 4.2 Authority. The Purchaser has full power and authority to enter into and to perform this Agreement in accordance with its terms.

The officers or representatives of the Company have made available to the Purchaser any and all written information which it has requested and have answered to the Purchaser's satisfaction all inquiries made by the Purchaser; and the Purchaser has sufficient knowledge and experience in finance and business that it is capable of evaluating the risks and merits of its investment in the Company and the Purchaser is able financially to bear the risks thereof (including a complete loss of its investment). 4.4 Limitations on Disposition. The Purchaser recognizes that no public market exists for the Securities, and none may exist in the future. The Purchaser understands that it must bear the economic risk of this investment indefinitely unless its Securities are registered pursuant to the Securities Act or an exemption from such registration is available, and unless the disposition of such Securities is qualified or registered under applicable state securities laws or an exemption from such qualification or registration is available, and that the Company has no obligation or present intention of so registering the Securities. The Purchaser further understands that there is no assurance that any exemption from the Securities Act will be 13 available, or, if available, that such exemption will allow it to transfer any or all the Securities, in the amounts, or at the times it might propose. The Purchaser understands that at the present time Rule 144 promulgated under the Securities Act by the Securities and Exchange Commission ("Rule 144") is not applicable to sales of the Securities because the Company is not subject to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and the information concerning the Company specified in Rule 144 is not publicly available. The Purchaser further acknowledges that the Company is not presently under any obligation to register under Section 12 of the Exchange Act or to make publicly available the information specified in Rule 144 and that it may never be required to do so. 4.5 Foreign Purchaser.

From and after the date of this Agreement, and thereafter so long as the Note remains outstanding, the Company will duly perform and observe, for the benefit of the Purchaser, each and all of the covenants and agreements hereinafter set forth. 7.1 Other Indebtedness; Restricted Payments. (a) From and after the Closing, (i) neither the Company nor any Subsidiary shall (A) create, incur, assume or directly or indirectly guarantee or in any other manner become directly or indirectly liable for any Indebtedness (as hereinafter defined) that is pari passu with, or senior in right of payment to, the Note or that is secured by any assets or properties of the Company or any Subsidiary; or (B) directly or indirectly, create, incur, assume or suffer to exist any Security Interest with respect to any of their respective properties or assets. Notwithstanding the foregoing, the Company shall have the right to incur and suffer to exist: (x) Indebtedness that is secured by any accounts receivable of the Company or any Subsidiary which Indebtedness shall not exceed 50% of the aggregate accounts receivable in existence from time to time, and (y) any Purchase Money Indebtedness (as hereinafter defined). For the purposes of this Section 7.1(a), "Indebtedness" shall mean indebtedness for borrowed money or for the deferred purchase price of property or services or which is evidenced by a note, bond, debenture or similar instrument, and "Purchase Money Indebtedness" shall mean any Indebtedness incurred for the acquisition of intellectual property rights, property, plant or equipment used or useful in the business of the Company or any of its Subsidiaries. (b) From and after the Closing, neither the Company nor any Subsidiary shall declare or pay any dividend or other distribution in respect of its capital stock (other than dividends or distributions payable solely in shares of capital stock of the Company), or purchase, redeem or otherwise acquire or retire for value any capital stock of the Company or any Subsidiary; provided, however, that this restriction shall not apply to the repurchase of shares of capital stock from employees, officers, directors, consultants or other persons performing services for the Company or any Subsidiary pursuant to agreements under which the Company has the option to repurchase such shares at cost upon the occurrence of certain events, such as the termination of employment, or through the exercise of any right of first refusal; provided, further, however, that such permitted repurchases shall not exceed the limits contained in Section 8(a)(v) and Section 8(b)(v) of Article IV of the Charter, as the same may be amended from time to time. (c) The provisions of this Section 7.1 shall terminate and be of no further force or effect upon the conversion or indefeasible repayment in full of the Note and all accrued interest thereon and any and all expenses or liabilities relating thereto. 7.2 Changes to Celgene Transaction. In the event that the Company agrees to any change in (a) the interest rate, payment terms, conversion provisions or maturity date of the Celgene Note, or (b) the exercise terms, adjustment provisions or expiration date of the Celgene Warrant (collectively (a) and (b) are referred to herein as a "Proposed Change"), the Company 16 shall promptly notify the Purchaser of such Proposed Change and certify to the Purchaser (i) whether such change has been agreed to by the Company solely in consideration of a waiver of a covenant relating to the Celgene Note or a waiver of a default under the Celgene Note, (ii) whether or not Celgene's consideration for the Proposed Change (the "Consideration") is in a form that is reasonably comparable in kind and value to that which the Purchaser could provide ("Comparable Consideration"), (iii) if Comparable Consideration exists, the identity and amount of such Comparable Consideration, an explanation of how such Comparable Consideration has been determined and that such Comparable Consideration is fair and proportionate to that being offered by Celgene ("Fair"), and (iv) if Comparable Consideration does not exist, that the Consideration was arrived at through arms length negotiations. If such changes shall have been agreed to by the Company solely in consideration of a waiver of a covenant relating to the Celgene Note or a waiver of an event of default under the Celgene Note, then the Company shall offer the Purchaser corresponding changes to the Note or Warrant substantially simultaneously with the changes to the Celgene instruments in exchange for a comparable waiver from the Purchaser. If Comparable Consideration exists, the Company shall offer the Purchaser corresponding changes to the Note and Warrant, as the case may be, substantially simultaneously with the changes to the Celgene instruments in exchange for the payment by the Purchaser of Comparable Consideration and the Purchaser shall notify the Company in writing within five (5) business days after receipt of the offer whether or not the Purchaser accepts such offer or, alternatively, whether it will accept such offer, subject to further negotiations regarding the Fairness of the Comparable Consideration. If the Purchaser's notice indicates its willingness to accept the offer subject to such further negotiations, the Company agrees to provide to Purchaser such evidence as Purchaser shall reasonably require in connection with the Purchaser's determination of the Purchaser's Proposal (as defined below) and, within ten (10) business days of receipt of such information, the Purchaser shall certify to the Company the nature and amount of consideration that Purchaser deems is Fair ("Purchaser's Proposal"). In the event that the Purchaser and the Company are unable to agree on which of the Comparable Consideration or the Purchaser's Proposal is Fair or to compromise their respective positions on such proposals within ten (10) business days after the Company's receipt of Purchaser's notice, such dispute shall be referred for resolution to a firm of independent certified public accountants mutually acceptable to the Purchaser and the Company. The accounting firm so selected by agreement shall be requested to deliver to the Purchaser and the Company, within twenty (20) business days after its selection, a written report regarding which of the proposals it deems to be the closest to Fair, it being expressly agreed by the Purchaser and the Company that the authority of such firm shall be limited solely to a choice between the Comparable Consideration or the Purchaser's Proposal. Upon the delivery of such report in final form, the determination of such accounting firm shall be conclusive and binding upon the parties hereto so that changes to the Note and Warrant corresponding to the Proposed Change shall be made by the Company in exchange for the delivery of the consideration selected in such final report, and Purchaser shall deliver such consideration in exchange for such corresponding changes to the Note and Warrant. The Purchaser and the Company shall cooperate fully and provide full access to such accounting firm in connection with its determination hereunder, provided always that the parties shall not, without the consent of the other party, provide any evidence or information to such accounting firm that has not been provided to such other party prior to the date of submission of the 17 Purchaser's Proposal. The costs and expenses of any such accounting firm selected by the parties shall be paid by the party whose proposal on consideration is not selected. If Comparable Consideration does not exist, then the Company shall offer the Purchaser the opportunity to negotiate in good faith changes to the Note or Warrant, as the case may be, comparable to the Proposed Change in exchange for such consideration as the Company and the Purchaser mutually believe is fair to both parties under the circumstances. 7.3 No Impairment. The Company will not take or permit any action, or cause or permit any Subsidiary to take or permit any action, that impairs or adversely affects the rights of the Purchaser under this Agreement, the Note or the Warrant. 7.4 Notification of Certain Matters. The Company shall deliver to the Purchaser the following notices, in each case under the circumstances and in accordance with the procedures as described herein: (a) Notice of Default or Event of Default. promptly, and in any event within five days after becoming aware of the existence of any default or Event of Default (as defined in Section 7 of the Note) or that any notice has been given or any action has been taken with respect to a claimed default or Event of Default under the Note or that any notice has been given or any action has been taken with respect to a claimed default or Event of Default of the type referred to in Section 7 of the Note, a written notice specifying the nature and period of existence thereof and what action the Company is taking or proposes to take with respect thereto; (b) Notices from Governmental Entity. promptly, and in any event within five days of receipt thereof, copies of any notice to the Company or any Subsidiary from any federal or state Governmental Entity relating to any order, ruling, statute or other law or regulation that could reasonably be expected to have a Company Material Adverse Effect; (c) Liquidity. promptly, and in any event within ten days, (i) after there is a reasonable likelihood that the Company's financial resources shall not be sufficient to conduct the business of the Company and its Subsidiaries, as then presently conducted and as then proposed to be conducted, for the ensuing twelve-month period, or (ii) after the Company becomes aware that its cash on hand, including readily marketable securities, is less than the then outstanding principal amount of the Note; and (d) Requested Information. with reasonable promptness, such other data and information relating to the business, operations, affairs, financial condition, assets or properties of the Company or any Subsidiary, including, without limitation, copies of all notices and other materials provided to members of the Board of Directors of the Company, or relating to the ability of the Company to perform its obligations hereunder and under the Note as from time to time may be reasonably requested by the Purchaser, provided, however, that the Company reserves the right to exclude any information that any executive officer of the Company or the Company's counsel, in their sole discretion, determines could adversely affect or jeopardize the attorney-client privilege between the Company and its counsel, or is necessary to protect highly confidential or competitively sensitive information (of the Company or of third parties). 18 7.5 Inspection Rights. The Company shall permit the representatives of the Purchaser: (a) Prior to Closing. Prior to the Closing, at the expense of the Purchaser, to visit and inspect any of the offices or properties of the Company or any Subsidiary, to examine all their respective books of account, records, reports and other papers not contractually required of the Company or such Subsidiary to be kept confidential or secret, to make copies and extracts therefrom, and to discuss their respective affairs, finances and accounts with their respective officers and independent public accountants, consultants and advisors, (and by this provision the Company authorizes said accountants, consultants and advisors, to discuss the affairs, finances and accounts of the Company and each Subsidiary), all at such times and as often as may be requested.

(d) Confidentiality. As to so much of the information and other material furnished under or in connection with this Agreement (whether furnished before, on or after the date hereof, including without limitation information furnished pursuant to Section 7.5 hereof) as constitutes or contains confidential business, financial or other information of the Company or any Subsidiary, the Purchaser covenants for itself and its directors, officers, employees, agents and advisors (collectively "Representatives") that it will maintain the confidentiality of such information and it will use due care to prevent its Representatives from disclosing such information to persons other than other Representatives to whom such information must necessarily be disclosed in connection with Purchaser's investment in the Note and Warrant and any other transactions or dealings between Purchaser and the Company; provided, however, that the Purchaser may disclose or deliver any information or other material disclosed to or received by it if such information or other material (i) is or becomes available to the public other than as a result of a breach of this Section 7.5(d), (ii) was or becomes available to the Purchaser on a non-confidential basis from a source other than the Company or any of its Subsidiaries (whether before or after disclosure by the company or any of its Subsidiaries), provided that to the 19 Purchaser's knowledge such source is not prohibited from disclosing such information to the Purchaser by contractual, legal or fiduciary obligation to the Company or any of its Subsidiaries or (iii) is independently developed by the Purchaser without violating its obligations hereunder or (iv) is required to be disclosed or delivered by law, regulation or judicial or administrative order. For purposes of this Section 7.5(d), "due care" means at least the same level of care that the Purchaser would use to protect the confidentiality of its own sensitive or proprietary information. This obligation shall survive any termination of this Agreement. 7.6 Compliance. The Company will and will cause each Subsidiary to comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, Environmental Laws, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. 7.7 Insurance. The Company will and will cause each Subsidiary to maintain, with financially sound and reputable insurers, insurance with respect to their respective properties, businesses and products against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated. 7.8 Maintenance. The Company will and will cause each Subsidiary to maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section 7.8 shall not prevent the Company or any Subsidiary from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect. 7.9 Taxes. The Company will and will cause each Subsidiary to file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a lien on properties or assets of the Company or any Subsidiary, provided that neither the Company nor any Subsidiary need pay any such tax or assessment or claims if (i) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or such Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment of all such taxes and assessments in the aggregate could not reasonably be expected to have a Company Material Adverse Effect. 20 7.10 Preservation of Corporate Existence.
