SECTION 2. Buyer’s Representations and Warranties. Each Buyer represents and warrants to the Company with respect to only itself that as of the date hereof:

(a) Investment Purpose. Such Buyer is acquiring the Notes for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted from registration under the Securities Act; provided, however, that by making the representations herein, such Buyer does not agree to hold any of the Notes or the shares of Common Stock issued upon conversion of the Notes, including any Additional Shares (as defined in the Indenture) and shares of Common Stock issued in payment of the Company Conversion Provisional Payment (as defined in the Indenture) (collectively, the “Conversion Shares” and, together with the Notes, the “Securities”) for any minimum or other specific term and reserves the right to dispose of the Securities at any time; provided, further, that such disposition shall be in accordance with or pursuant to a registration statement or an exemption under the Securities Act.

(b) Accredited Investor and Qualified Institutional Buyer Status. Such Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D under the Securities Act and a “qualified institutional buyer” as that term is defined in Rule 144A(a) under the Securities Act as of the date of this Agreement and was not organized for the specific purpose of acquiring the Securities.

(c) Reliance on Exemptions. Such Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Buyer set forth herein and in the applicable Note in order to determine the availability of such exemptions and the eligibility of such Buyer to acquire the Securities.

(d) Information. Such Buyer believes it (i) has been furnished with or believes it has had full access to all of the information that it considers necessary or appropriate for deciding

whether to purchase the Securities, including all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by such Buyer, including a copy of the Confidential Private Placement Memorandum, (ii) has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the Offering, (iii) can bear the economic risk of a total loss of its investment in the Securities and (iv) has such knowledge and experience in business and financial matters so as to enable it to understand the risks of and form an investment decision with respect to its investment in the Securities. Neither such inquiries nor any other due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall limit, modify, amend or affect the Company’s representations and warranties contained in this Agreement or any other Transaction Document and the Buyer’s right to rely thereon.

(e) No Governmental Review. Such Buyer understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(f) Transfer or Resale. Such Buyer understands that, except as provided in the Registration Rights Agreement, the Securities have not been registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred without registration under the Securities Act or an exemption therefrom and that, in the absence of an effective registration statement under the Securities Act, such Securities may only be sold under certain circumstances as set forth in the Securities Act. In that connection, such Buyer is aware of Rule 144 under the Securities Act and the restrictions imposed thereby.

(g) Legends.

(1) Such Buyer understands that, until the expiration of the holding period applicable to sales thereof under Rule 144(k) (or any successor provision), any certificate evidencing such Notes (and all securities issued in exchange therefor or in substitution thereof, other than Common Stock, if any, issued upon conversion thereof), which shall bear the legend set forth in Section 2(g)(2) of this Agreement, if applicable) shall bear a legend in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION THEREFROM. THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY THE SECURITIES.

The Company may place the following legend on any Note, as appropriate, held by or transferred to an “affiliate” (as defined in Rule 501(b) of Regulation D under the Securities Act) of the Company:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE HELD BY A PERSON WHO MAY BE DEEMED TO BE AN AFFILIATE OF THE ISSUER FOR PURPOSES OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY BE SOLD ONLY IN COMPLIANCE WITH RULE 144, PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

The legends set forth above shall be removed and the Company shall issue a new Note, as appropriate, of like tenor and aggregate principal amount or number of shares, as appropriate, and which shall not bear the restrictive legends required by this Section 2(g)(1), (i) if such Notes are registered for resale under the Securities Act and are transferred or sold pursuant to such registration, (ii) if, in connection with a sale transaction, such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that such sale, assignment or transfer of the Notes may be made without registration under the Securities Act, or (iii) upon expiration of the two-year period under Rule 144(k) of the Securities Act (or any successor rule) if the holder of the Securities has not been an “affiliate” (as defined in Rule 501(b) of Regulation D under the Securities Act) during the preceding three (3) months.

(2) Such Buyer understands that any stock certificate representing Conversion Shares shall bear a legend in substantially the following form (unless (i) such Conversion Shares have been transferred or sold pursuant to an effective registration statement, (ii) such Conversion Shares, as appropriate, have been transferred or sold pursuant to the exemption from registration provided by Rule 144 under the Securities Act, (iii) such Conversion Shares, as appropriate, may be transferred pursuant to Rule 144(k) under the Securities Act, or (iv) unless otherwise agreed by the Company in writing with written notice to the transfer agent):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION THEREFROM. THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY THE SECURITIES.

The Company may instruct the transfer agent to place the following legend on any certificate evidencing shares of Common Stock held by or transferred to an “affiliate” (as defined in Rule 501(b) of Regulation D under the Securities Act) of the Company:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE HELD BY A PERSON WHO MAY BE DEEMED TO BE AN AFFILIATE OF THE ISSUER FOR

PURPOSES OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY BE SOLD ONLY IN COMPLIANCE WITH RULE 144, PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A VALID EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

The legends set forth above shall be removed and the Company shall issue the relevant Securities without such legends to the holder of the Securities upon which it is stamped, (i) if such Securities are registered for resale under the Securities Act and are transferred or sold pursuant to such registration, (ii) if, in connection with a sale transaction, such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that such sale, assignment or transfer of the Securities may be made without registration under the Securities Act, or (iii) upon expiration of the two-year period under Rule 144(k) of the Securities Act (or any successor rule) if the holder of the Securities has not been an “affiliate” (as defined in Rule 501(b) of Regulation D under the Securities Act) during the preceding three (3) months.

(3) Such Buyer understands that, in the event Rule 144(k) as promulgated under the Securities Act (or any successor rule) is amended to change the two-year or three-month periods under Rule 144(k) (or the corresponding periods under any successor rule), (i) each reference in Sections 2(g)(1) and 2(g)(2) of this Agreement to “two (2) years” or the “two-year period” and to “three (3) months” shall be deemed for all purposes of this Agreement to be references to such changed period or periods, and (ii) all corresponding references in the Notes shall be deemed for all purposes to be references to the changed period or periods, provided that such changes shall not become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws.

(h) Authorization; Enforcement; Validity. This Agreement and the Registration Rights Agreement have been duly and validly authorized, executed and delivered on behalf of such Buyer and are valid and binding agreements of such Buyer enforceable against such Buyer in accordance with their terms, subject as to enforceability to general principles of equity and to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(i) Residency. Such Buyer is a resident of that country or state specified in its address on the Schedule of Buyers attached hereto as Exhibit A.

(j) No Conflicts. The execution and performance of this Agreement and the Registration Rights Agreement do not conflict with any agreement to which such Buyer is a party or is bound thereby, any court order or judgment addressed to such Buyer, or the constituent documents of such Buyer, except for those conflicts that would not, individually or in the aggregate, have an adverse effect on the Buyer’s authority or ability to perform its obligations under this Agreement or the Registration Rights Agreement.

(k) Conversion Limitation. (A) Subject to Buyer’s election on the signature pages hereto to be governed by this Section 2(k)(A), each Buyer hereby agrees that in no event will it convert,

and the Company will not honor any conversion request presented to it that requests the conversion of, any of the Notes in excess of the number of such Notes, upon the conversion of which (x) the number of shares of Common Stock beneficially owned by such Buyer (other than the shares which would otherwise be deemed beneficially owned except for being subject to a limitation on conversion analogous to the limitation contained in this Section 2(k)(A)) plus (y) the number of shares of Common Stock issuable upon the conversion of such Notes, would be equal to or exceed 9.99% of the number of shares of Common Stock then issued and outstanding (after giving effect to such conversion), it being the intent of the Company and the Buyers that no Buyer electing to be governed by this Section 2(k)(A) be deemed at any time to have the power to vote or dispose of greater than 9.99% of the number of shares of Common Stock issued and outstanding. As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”). To the extent that the limitation contained in this Section 2(k)(A) applies (and without limiting any rights the Company may otherwise have), the Company may rely on the Buyer’s determination of whether the Notes are convertible pursuant to the terms hereof, the Company having no obligation whatsoever to verify or confirm the accuracy of such determination, and the submission of the Conversion Notice (as that term is defined in the Note) by the Buyer shall be deemed to be the Buyer’s representation that the Notes specified therein are convertible or exercisable pursuant to the terms hereof. Nothing contained herein shall be deemed to restrict the right of a Buyer to convert the Notes at such time as the conversion thereof will not violate the provisions of this Section 2(k)(A). By written notice to the Company, the Buyer may increase or decrease the maximum percentage stated in this paragraph to any other percentage not in excess of 19.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61^st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Buyer and not to any other holder of Notes. Notwithstanding anything to the contrary, this Section shall not apply to a Buyer unless the Buyer has elected to be governed by this Section by so indicating on the signature page.

(B) Subject to Buyer’s election on the signature pages hereto to be governed by this Section 2(k)(B), each Buyer hereby agrees that in no event will it convert, and the Company will not honor any conversion request presented to it that requests the conversion of, any of the Notes in excess of the number of such Notes, upon the conversion of which (x) the number of shares of Common Stock beneficially owned by such Buyer (other than the shares which would otherwise be deemed beneficially owned except for being subject to a limitation on conversion analogous to the limitation contained in this Section 2(k)(B)) plus (y) the number of shares of Common Stock issuable upon the conversion of such Notes, would be equal to or exceed 4.99% of the number of shares of Common Stock then issued and outstanding (after giving effect to such conversion), it being the intent of the Company and the Buyers that no Buyer electing to be governed by this Section 2(k)(B) be deemed at any time to have the power to vote or dispose of greater than 4.99% of the number of shares of Common Stock issued and outstanding. As used herein, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act. To the extent that the limitation contained in this Section 2(k)(B) applies (and without limiting any rights the Company may otherwise have), the Company may rely on the Buyer’s determination of whether the Notes are convertible pursuant to the terms hereof, the Company having no obligation whatsoever to verify or confirm the accuracy of such determination, and the submission of the Conversion Notice (as that term is defined in the Note)

by the Buyer shall be deemed to be the Buyer’s representation that the Notes specified therein are convertible or exercisable pursuant to the terms hereof. Nothing contained herein shall be deemed to restrict the right of a Buyer to convert the Notes at such time as the conversion thereof will not violate the provisions of this Section 2(k)(B). By written notice to the Company, the Buyer may increase or decrease the maximum percentage stated in this paragraph to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61^st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Buyer and not to any other holder of Notes. Notwithstanding anything to the contrary, this Section shall not apply to a Buyer unless the Buyer has elected to be governed by this Section by so indicating on the signature page.

(l) Additional Acknowledgement. Each Buyer acknowledges that it has independently evaluated the merits of the transactions contemplated by this Agreement, the Indenture, the Notes and the Registration Rights Agreement, that it has independently determined to enter into the transactions contemplated hereby and thereby, that it is not relying on any advice from or evaluation by any other Buyer, and that it is not acting in concert with any other Buyer in purchasing the Securities offered hereunder. The Buyers have not taken any actions that would cause such Buyers to be deemed as members of a “group” for purposes of Section 13(d) of the Exchange Act, and the Company has no knowledge of any actions by the Buyers that would be inconsistent with this representation.

The Buyer’s representations and warranties made in this Section 2 are made solely for the purpose of permitting the Company to make a determination that the offer and sale of the Notes pursuant to this Agreement complies with applicable U.S. federal and state securities laws and not for any other purpose. Accordingly, the Company shall not rely on such representations and warranties for any other purpose.

SECTION 3. Representations and Warranties of the Company. The Company represents and warrants to each of the Placement Agents and each of the Buyers that as of the date hereof:

(a) Organization and Qualification. The Company and its Subsidiaries (as defined below) are corporations, partnerships or limited liability companies duly organized and validly existing in good standing under the laws of the jurisdiction in which they are incorporated or organized, and have the requisite corporate, limited liability company or partnership power and authorization to own their properties and to carry on their business as now being conducted. Copies of the Company’s Certificate of Incorporation and Bylaws, and all amendments thereto, have been filed as exhibits to the Company’s SEC Documents (as defined in Section 3(f) of this Agreement), are in full effect and have not been modified. Each of the Company and its Subsidiaries is duly qualified as a foreign corporation, partnership or limited liability company to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted and proposed to be conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect. As used in this Agreement, “Material Adverse Effect” means any material adverse effect on (i) the business, properties, assets, operations, results of operations or condition (financial or otherwise) or prospects of the Company and its Subsidiaries, taken as a whole, (ii) the transactions contemplated hereby or by the agreements and instruments to be

entered into in connection herewith, or (iii) the authority or ability of the Company to perform its obligations under the Transaction Documents (as defined below). “Subsidiary” means any entity in which the Company, directly or indirectly, owns or controls a majority of the ordinary voting power, capital stock or other equity or similar interests. The Company’s “Subsidiaries” are set forth on Schedule 3(a), and the Company’s “Significant Subsidiaries” are separately identified on that Schedule.

(b) Authorization; Enforcement; Validity. The Company has the requisite corporate power and authority to enter into and perform its obligations under this Agreement, the Indenture, the Notes, the Registration Rights Agreement, the Irrevocable Transfer Agent Instructions (as defined in Section 5 of this Agreement) and each of the other agreements entered into by the parties hereto in connection with the transactions contemplated by this Agreement (collectively, the “Transaction Documents”), and to issue and sell the Securities in accordance with the terms hereof and thereof. The execution and delivery of the Transaction Documents by the Company and the consummation by it of the transactions contemplated hereby and thereby, including, without limitation, the issuance and repayment of the Notes, the reservation for issuance and the issuance of the Conversion Shares issuable upon conversion thereof and the registration for resale of the Registrable Securities (as such term is defined in the Registration Rights Agreement), have been duly authorized by the Company’s Board of Directors and no further consent or authorization is required of the Company’s Board of Directors or shareholders. The Transaction Documents have been duly executed and delivered by the Company. The Transaction Documents constitute the valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except (i) as rights to indemnification and contribution may be limited by federal or state securities laws and policies underlying such laws and (ii) as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of creditors’ rights and remedies.

All of the Company’s outstanding shares have been, or upon issuance will be, validly issued and are fully paid and nonassessable and were issued in accordance with applicable federal and state securities laws. The Company’s Common Stock is registered pursuant to Section 12(g) of the Exchange Act and is listed for trading on The NASDAQ National Market (the “Principal Market”). No shares of the Company’s capital stock are subject to preemptive rights or any other similar rights and there are no securities or instruments to which the Company is a party containing anti-dilution or similar provisions that will be triggered by the issuance of the Securities as described in this Agreement. Except for rights created pursuant to the Transaction Documents and as set forth in the SEC Documents, (i) no shares of the Company’s capital stock are subject to any liens or encumbrances created by the Company; (ii) there are no outstanding options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, any shares of capital stock of the Company or any of its Subsidiaries, or contracts, commitments, understandings or arrangements by which the Company or any of its Subsidiaries is or may become bound to issue additional shares of capital stock of the Company or any of its Subsidiaries or options, warrants, scrip, rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities or rights convertible into, any shares of

capital stock of the Company or any of its Subsidiaries (other than any such options, warrants, scrip, rights, calls, commitments, securities, understandings and arrangement outstanding under plans disclosed in the SEC Documents); (iii) there are no outstanding debt securities, notes, credit agreements, credit facilities or other agreements, documents or instruments evidencing indebtedness of the Company or any of its Subsidiaries or by which the Company or any of its Subsidiaries is or may become bound other than the senior credit facility under that certain Credit Agreement dated as of May 16, 2003 among the Company, and the Northern Trust Company, LaSalle National Bank, Xxxxxx Trust and Savings Bank and National City Bank of Michigan/Illinois, as lenders (the “Senior Facility Lenders”), together with the documents now or hereafter related thereto (including without limitation, any guarantee agreements and any security documents), in each case as such agreements may be amended (including any amendment and restatement thereof), supplemented or otherwise modified from time to time, including any agreement extending the maturity of, refinancing, replacing, increasing the amount of, or otherwise restructuring all or any portion of the indebtedness under such agreement or any successor or replacement agreement and whether by the same or any other agent, lender or group of lenders (or other institutions)(the “Senior Facility”); (iv) there are no amounts outstanding under, and there will be no amounts due upon termination of, any credit agreement or credit facility other than the Senior Facility; (v) there are no financing statements securing obligations in any amounts greater than Fifty Thousand United States Dollars ($50,000), singly, or Two Hundred Fifty Thousand United States Dollars ($250,000) in the aggregate, filed in connection with the Company or any of its Subsidiaries other than in connection with the Senior Facility; (vi) there are no agreements or arrangements under which the Company or any of its Subsidiaries is obligated to register the sale of any of its securities under the Securities Act; (vii) there are no outstanding securities or instruments of the Company or any of its Subsidiaries which contain any redemption or similar provisions, and there are no contracts, commitments, understandings or arrangements by which the Company or any of its Subsidiaries is or may become bound to redeem a security of the Company or any of its Subsidiaries; (viii) the Company does not have any stock appreciation rights or “phantom” stock plans or agreements or any similar plan or agreement; (ix) the Company and its Subsidiaries have no liabilities or obligations required to be disclosed in the SEC Documents but not so disclosed in the SEC Documents, other than those incurred in the ordinary course of the Company’s or its Subsidiaries’ respective businesses and which, individually or in the aggregate, do not or would not have a Material Adverse Effect on the Company and its Subsidiaries taken as a whole; and (x) the Company does not have outstanding stockholder purchase rights or “poison pill” or any similar arrangement in effect giving any person or entity the right to purchase any equity interest in the Company upon the occurrence of certain events.

(d) Issuance of Securities. The Securities are duly authorized and, upon issuance in accordance with the terms of the applicable Transaction Documents, shall be (i) validly issued, fully paid and non-assessable and (ii) free from all taxes, liens and charges with respect to the issuance thereof, other than any liens or encumbrances created by or imposed by the Buyers, and shall not be subject to preemptive rights or other similar rights of shareholders of the Company. As of the Closing, at least 1,621,622 shares of Common Stock (subject to adjustment pursuant to the Company’s covenant set forth in Section 4(e) of this Agreement) will have been duly authorized and reserved for issuance upon conversion of the Notes. Upon conversion or issuance in accordance with the terms of the Notes, the Conversion Shares will be validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issue

thereof, other than any liens or encumbrances created by or imposed by the Buyers, with the holders being entitled to all rights accorded to a holder of Common Stock. Subject to the accuracy of the representations and warranties of each of the Buyers in this Agreement, the issuance by the Company of the Securities is exempt from registration under the Securities Act and applicable state securities laws.

(e) No Conflicts. 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 (including, without limitation, the issuance of the Notes and the reservation for issuance and issuance of the Conversion Shares) will not (i) result in a violation of the Company’s Certificate of Incorporation or Bylaws; (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its Subsidiaries is a party, except for such conflicts, defaults, terminations, amendments, accelerations, cancellations and violations as could not reasonably result, individually or in the aggregate, have a Material Adverse Effect; or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws and regulations and the rules and regulations of the Principal Market) applicable to the Company or any of its Subsidiaries or by which any property or asset of the Company or any of its Subsidiaries is bound or affected. Neither the Company nor any of its Subsidiaries is in violation of any material term of or in default under its Certificate of Incorporation, Bylaws or their organizational charter or bylaws, respectively. Neither the Company nor any of its Subsidiaries is in violation of any term of or in default under any contract, agreement, mortgage, indebtedness, indenture, instrument, judgment, decree or order or any statute, rule or regulation applicable to the Company or its Subsidiaries, except where such violations and defaults would not result, either individually or in the aggregate, in a Material Adverse Effect. The business of the Company and its Subsidiaries is not being conducted in violation of any law, ordinance or regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect. Except as specifically contemplated by this Agreement, as required under the Securities Act or as required by Blue Sky filings (but only to the extent that such filings may be made after the Closing), the Company is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency or any regulatory or self-regulatory agency or other person or entity in order for it to execute, deliver or perform any of its obligations under or contemplated by the Transaction Documents. All consents, authorizations, orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior to the date hereof and copies of such consents, authorizations, orders, filings and registrations have been delivered to the Buyers. The Company is not in violation of the listing requirements of the Principal Market, and has no actual knowledge of any facts which could reasonably lead to delisting or suspension of the Common Stock by the Principal Market in the foreseeable future. The Company and its Subsidiaries are not in violation of any covenants or other terms of its outstanding indebtedness for borrowed money, which could reasonably be expected to have a Material Adverse Effect. The Company and its Subsidiaries are currently unaware of any facts or circumstances which might give rise to any of the foregoing events set forth in this paragraph.

(f) SEC Documents; Financial Statements. Since July 1, 2001, the Company has filed all reports, schedules, forms, statements and other documents required to be filed by it with the Securities and Exchange Commission (the “Commission”) pursuant to the reporting requirements of the Exchange Act (all of the foregoing filed prior to or on the date hereof and all exhibits included therein and financial statements and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). As of the date of filing of such SEC Documents, each such SEC Document, as it may have been subsequently amended by filings made by the Company with the Commission prior to the date hereof, complied in all material respects with the requirements of the Exchange Act applicable to such SEC Document and did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they are or were made, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting requirements and published rules and regulations of the Commission with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles, consistently applied in the United States (“GAAP”), during the periods 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 exclude footnotes or may be condensed or summary statements), correspond to the books and records of the Company and fairly present in all material respects the financial position of the Company and its Subsidiaries as of the dates thereof and the results of operations and cash flows for the periods then ended.

The Company and its Subsidiaries do not have any knowledge of any infringement by the Company or its Subsidiaries of Intellectual Property rights of others, or of any development of similar or identical trade secrets or technical information by others that would have a material adverse effect.

Except for the issuance of the Securities and the transactions contemplated by this Agreement and the Company’s intended use of the net proceeds from the sale of the Notes (which such information shall be fully disclosed in the Current Report on Form 8-K filed pursuant to Section 4(g)(1) hereof), the Company has not provided the Buyers with, and the Confidential Private Placement Memorandum does not contain, material non-public information.

(t) Acknowledgment Regarding Buyer’s Purchase of Securities.

The Company further acknowledges that no Buyer is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such Buyer’s purchase

The Company further represents to each Buyer that the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives. The Company acknowledges and agrees that no Buyer makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 2.

The Company has not taken any steps to seek protection pursuant to any bankruptcy law nor does the Company have any knowledge or reason to believe that its creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. The Company is not as of the date hereof, and after giving effect to the transactions contemplated hereby to occur at each Closing, will not be Insolvent (as defined below).

No executive officer of the Company, to the knowledge of the Company, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters.

(2) The Company and its Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting employment and employment practices, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

The Company and its Subsidiaries have good and marketable title in fee simple to all real property and good and marketable title to all personal property owned by them which is material to the business of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects except as provided in the SEC Documents or the Senior Facility and except for such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company and any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and facilities by the Company and its Subsidiaries.

as of the date hereof, and any and all applicable rules and regulations promulgated by the SEC thereunder that are effective with respect to the Company as of the date hereof, except where such noncompliance would not have, individually or in the aggregate, a Material Adverse Effect.

(k) Tax Matters. If the Company shall be required to withhold or deduct any tax or other governmental charge from any payment made hereunder or under any Note to any Buyer, then, subject to the last sentence of this Section 4(k), the Company shall pay to such Buyer such additional amounts as are necessary such that such Buyer actually receives the amount such Buyer would have received if no such withholding or deduction had been required. If any Buyer is organized under the laws of a jurisdiction other than the United States, any State thereof or the District of Columbia (a “Non-United States Buyer”), such Buyer shall deliver to the Company either (a) two (2) copies of either United States Internal Revenue Service Form W-8BEN or Form W-8ECI, or (b) in the case of a Non-United States Buyer claiming exemption from United States Federal withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the “Code”) with respect to payments of “portfolio interest”, a certificate in form and substance reasonably acceptable to the Company representing that such Non-United States Buyer is not a bank for purposes of Section 881(c) of the Code, is not a ten percent (10%) shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Company and is not a controlled foreign corporation related to the Company (within the meaning of Section 864(d)(4) of the Code), together with Internal Revenue Service Form W-8 or W-9, as applicable, in all cases such forms and other documents being properly completed and duly executed by such Non-United States Buyer claiming complete exemption from United States Federal withholding tax on payments of interest by the Company (or accruals of original issue discount) under the Notes.

The Equity Limitation shall not apply (i) to the issuance of Conversion Shares

pursuant to the Notes, (ii) to the issuance of securities pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options, in each case outstanding on the date hereof, provided such securities, warrants and options are not amended after the date hereof, (iii) if holders representing a majority of the outstanding principal amount of the Notes give their prior written consent to such issuance or sale, (iv) if the issuance is pursuant to employee benefits plans approved by the Company’s Board of Directors, (v) to the filing of a Registration Statement on Form S-8, (vi) if the securities are issued for consideration other than cash in connection with a bona fide business acquisition by the Company whether by merger, consolidation, purchase of assets, sale or exchange of stock or otherwise, or (vii) if the issuance is in connection with a (A) commercial banking arrangement, (B) equipment financing, (C) sponsored research, (D) collaboration, (E) technology licensing, (F) development agreement or (G) other strategic partnership; provided, however, that with respect to (C) through (G) hereof, the primary purpose of such transaction is not to raise equity capital.

(n) CUSIP Numbers. The Company in issuing the Securities shall use “CUSIP” numbers (if then generally in use), and shall use such “CUSIP” numbers in notices to holders as a convenience to holders thereof; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice to such holders and that reliance may be placed only on other identification numbers printed on such Securities, and any such Company action referenced in such notice (including, without limitation, redemption or automatic conversion of Notes) shall not be affected by any defect in or omission of such numbers.

(o) Accounting Matters. The Company shall use its reasonable best efforts to cause to be delivered to the Buyers a letter in form and substance reasonably acceptable to the Buyers and reasonably customary in scope and substance for comfort letters delivered by independent public accountants in connection with offerings similar to the Offering.

(p) Nonpublic Information. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide those Buyers listed on Schedule 4(p) with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the 8-Ks with the SEC pursuant to Section 4(g) hereof without the express written consent of such Buyers; provided, however that the foregoing shall not restrict in any way the distribution of any information to any such Buyers by the Company or its Subsidiaries and its and each of their respective officers, directors, employees and agents (i) as reasonably required by the terms of the Transaction Documents or (ii) in connection with any request by or on behalf of the Company to waive, amend or modify any provision of the Transaction Documents.

(r) Independent Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under any Transaction Document are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations

of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents and the Company has no knowledge of any facts that would establish that the Buyers are acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Buyer confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.

SECTION 5. Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates or credit shares to the applicable balance accounts at DTC, registered in the name of each Buyer or their respective nominee(s), for the Conversion Shares in such amounts as specified from time to time by a Buyer to the Company upon conversion of the Notes and in accordance with their respective terms (the “Irrevocable Transfer Agent Instructions”), substantially in the form attached hereto as Exhibit E. Prior to transfer or sale pursuant to a registration statement or Rule 144 under the Securities Act of the Conversion Shares, all such certificates shall bear the restrictive legend specified in Section 2(g) of this Agreement. The Company represents and warrants that no instruction inconsistent with the Irrevocable Transfer Agent Instructions referred to in this Section 5 will be given by the Company to its transfer agent and that the Securities shall be freely transferable on the books and records of the Company as and to the extent provided in this Agreement, the Notes, the Indenture and the Registration Rights Agreement. Subject to the Indenture, if a Buyer provides the Company with an opinion of counsel, in form reasonably acceptable to the Company, to the effect that a sale, assignment or transfer of the Securities has been made without registration under the Securities Act or that the Securities can be sold pursuant to Rule 144(k) without any restriction as to the number of securities acquired as of a particular date that can then be immediately sold, and provides such representations that the Company shall reasonably request confirming compliance with the requirements of Rule 144, the Company shall permit the transfer, and, in the case of the Conversion Shares, promptly instruct its transfer agent to issue one or more certificates, or credit shares to one or more balance accounts at DTC, in such name and in such denominations as specified by such Buyer and without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Buyers by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5, that the Buyers shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

SECTION 6. Conditions to the Company’s Obligation to Close. The obligation of the Company to issue and sell the Notes to each respective Buyer at the Closing is subject to the

satisfaction, at or before the Closing Date, of each of the following conditions, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion by providing such Buyer with prior written notice thereof:

(a) Transaction Documents. Such Buyer shall have executed each of the Transaction Documents to which it is a party and delivered the same to the Company.

In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and the Placement Agents’ agreement to act as exclusive placement agents and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Placement Agent and each Buyer and each other holder of the Securities and all of their shareholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (collectively, “Claims”), incurred by any Indemnitee as a result of, or arising out of, or relating to (i) an untrue statement or alleged untrue statement of a material fact contained in the Confidential Private Placement Memorandum, or in any amendment or supplement thereto, or in any Blue Sky filings executed by the Company or based on any information furnished in writing by the Company and filed in any jurisdiction in order to qualify any or all of the Securities under (or obtain exemption from) the securities laws thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (ii) any breach of any representation, warranty,

covenant or agreement made by the Company in the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Claims which is permissible under applicable law. Subject to Section 8(b) of this Agreement, the Company shall reimburse the Indemnitees, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with the investigating or defending any such Claim.

(b) Procedures for Indemnification. Promptly after an Indemnitee has knowledge of any Claim as to which such Indemnitee reasonably believes indemnity may be sought or promptly after such Indemnitee receives notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnitee shall, if a Claim in respect thereof is to be made against the Company under this Section 8, deliver to the Company a written notice of such Claim, and the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Company and the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel if, in the reasonable opinion of counsel retained by the Company, the representation by such counsel of the Indemnitee and the Company would be inappropriate due to actual or potential differing interests between such Indemnitee and the Company; provided, further, that the Company shall not be responsible for the reasonable fees and expense of more than one (1) separate legal counsel for such Indemnitee. In the case of an Indemnitee, the legal counsel referred to in the immediately preceding sentence shall be selected by the Buyers holding at least a majority in interest of the Securities to which the Claim relates. The Indemnitee shall cooperate fully with the Company in connection with any negotiation or defense of any such action or Claim by the Company and shall furnish to the Company all information reasonably available to the Indemnitee which relates to such action or Claim. The Company shall keep the Indemnitee fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company shall not be liable for any settlement of any Claim effected without its prior written consent; provided, however, that the Company shall not unreasonably withhold, delay or condition its consent. The Company shall not, without the prior written consent of the Indemnitee, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a full release from all liability in respect to such Claim, action and proceeding. The failure to deliver written notice to the Company as provided in this Agreement shall not relieve the Company of any liability to the Indemnitee under this Section 8, except to the extent that the Company is materially prejudiced in its ability to defend such action.

(c) Survival of Representations and Warranties; Indemnification Obligations. The representations and warranties of the Buyers and the Company set forth herein and the obligations of the Company under this Section 8 shall survive the transfer of the Securities by the Indemnitees.

SECTION 9. Miscellaneous.

(a) Governing Law; Jurisdiction; Waiver of Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the

internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

Re: Reservation of Shares of Common Stock Pursuant to Sale by Quixote Corporation of up to $40,000,000 in Aggregate Principal Amount of 7% Convertible Senior Subordinated Notes due 2025

Ladies and Gentlemen:

Quixote Corporation, a Delaware corporation (the “Company”), has agreed to sell to the buyers listed on Schedule A hereto (the “Buyers”), on the date hereof, Forty Million Dollars ($40,000,000) in aggregate principal amount of 7% Convertible Senior Subordinated Notes due 2025 (the “Notes”), convertible into shares of the common stock, $0.01²/₃ par value per share (the “Common Stock”) of the Company pursuant to that certain Securities Purchase Agreement dated as of February 9, 2005, by and among the Company and each Buyer (the “Securities Purchase Agreement”). Capitalized terms used herein without definition have the meanings assigned to them in the Securities Purchase Agreement.

Pursuant to the terms of that certain Agreement for Stock Transfer Service dated December 1, 1995 between the undersigned and the First National Bank of Boston (as predecessor to Equiserve Trust Company, N.A.), and in particular but not by way of limitation, Section 6.02 thereof, you are hereby instructed to:

Establish as of the date of this letter a reserve of 1,621,622 shares of Common Stock for issuance to holders of Notes upon conversion of their Notes (the “Conversion Share Reserve”). The Conversion Share Reserve shall be adjusted to appropriately reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Common Stock), reorganization, recapitalization, reclassification, exchange or other like change with respect to Common Stock occurring on or after the date hereof.

A registration statement on Form S-3 to register the Common Stock issuable out of the Conversion Share Reserve (the “Registration Statement”) will be filed with the Securities and Exchange Commission (the “Commission”) on or before March 11, 2005. We will forward to you copies of the filing promptly after it is declared or deemed effective by the Commission.

Until the Registration Statement is declared effective by the Commission, the certificates evidencing the shares of Common Stock issued out of the Conversion Share Reserve will bear the restrictive legend set forth below:

Until the Registration Statement is declared effective by the Commission, certificates evidencing shares of Common Stock held by or transferred to an “affiliate” (as defined in Rule 501(b) of Regulation D under the Securities Act) of the Company also will bear the restrictive legend set forth below:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE HELD BY A PERSON WHO MAY BE DEEMED TO BE AN AFFILIATE OF THE ISSUER FOR PURPOSES OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY BE SOLD ONLY IN COMPLIANCE WITH RULE 144, PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A VALID EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

Upon the conversion of any Notes, the Company will deliver to you instructions to issue a certificate or certificates evidencing the shares of Common Stock to be issued out of the Conversion Share Reserve, and such instructions will indicate whether such certificate or certificates shall bear any of the legends set forth above. In the event of any transfer of shares of Common Stock issued out of the Conversion Share Reserve, so long as you have previously received (i) an opinion of the Company’s outside counsel (which the Company shall direct be delivered to you by such outside counsel upon the effectiveness of the Registration Statement covering the resales of the Common Stock) stating that a Registration Statement covering the resales of the Common Stock has been declared effective by the Commission under the Securities Act (the “Opinion”), (ii) a certification from the clearing broker for the Buyers as to the fact that the sale of the Common Stock was made in compliance with the Plan of Distribution set forth in the Registration Statement (the “Broker Certification”), (iii) a copy of the Registration Statement and (iv) confirmation from the Company that sales are permitted under the Registration Statement, the certificates representing the Common Stock sold pursuant to the Registration Statement shall not bear any legend restricting transfer of the Common Stock thereby and should not be subject to any stop-transfer restriction.

EXHIBIT F

FORM OF COMPANY COUNSEL OPINION

The Company is a corporation validly existing in good standing under the laws of the State of Delaware, with all requisite corporate power and authority to own, lease and operate its properties and assets, to conduct its business as described in the Confidential Private Placement Memorandum, and to enter into and perform its obligations under the Transaction Documents.

The Subsidiaries are corporations validly existing in good standing under the laws of their respective jurisdictions of incorporation, with all requisite corporate power and authority to own, lease and operate its properties and assets, to conduct their businesses as described in the Confidential Private Placement Memorandum.

The execution, delivery and performance of the Transaction Documents have been duly authorized by all necessary corporate action on the part of the Company and the Transaction Documents have been duly executed and delivered by the Company.

The Transaction Documents constitute the legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except (i) as rights to indemnification and contribution may be limited by federal or state securities laws and policies underlying such laws and (ii) as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of creditors’ rights and remedies.

The execution and delivery by the Company of the Transaction Documents do not, and the Company performance of its obligations under the Transaction Documents will not, (i) violate the Company’s Certificate of Incorporation or By-Laws, (ii) violate, breach or result in a default under, any existing obligation of or restrictions on the Company under any other agreement listed in an exhibit to the Company’s most recent annual report on Form 10-K, any quarterly report on Form 10-Q filed since such annual report or any current report on Form 8-K filed since such annual report, (iii) breach or otherwise violate any existing obligation of or restriction on the Company under any order, judgment or decree of any state or federal court or governmental authority binding on the Company, and known to us, or (iv) to our knowledge, violate any current Delaware or New York federal statute, rule or regulation that we have recognized as applicable to the Company or to transactions of the type contemplated by the Transaction Documents.

The Notes have been duly authorized by all necessary corporate action on the part of the Company and, upon payment for and delivery of the Notes in accordance with the Securities Purchase Agreement, to our knowledge will be made and issued free of preemptive or similar rights.

The Conversion Shares have been duly authorized and reserved for issuance upon conversion of the Notes by all necessary corporate action on the part of the Company and, upon

conversion of the Notes and delivery of the Conversion Shares in accordance with the Notes, the Conversion Shares will be validly issued, fully paid and nonassessable and to our knowledge, free of preemptive or similar rights.

No order, consent, permit or approval of any Delaware, New York or federal governmental authority that we have recognized as applicable and material to the Company or to the transactions of the type contemplated by the Transaction Documents is required on the part of the Company for the execution and delivery of, and performance of its obligations under, the Transaction Documents except as may be required under applicable state and federal securities laws and regulations applicable to the offer and sale of the Securities and by federal and state securities laws with respect to the Company’s obligations under the Registration Rights Agreement.

Assuming the accuracy of your representations in Section 2 of the Securities Purchase Agreement, no registration under the Securities Act, and no qualification of the Indenture under the Trust Indenture Act, is required for the purchase and sale of the Notes in the manner contemplated by the Securities Purchase Agreement and the Confidential Private Placement Memorandum. Assuming that the exemption provided by Section 3(a)(9) of the Securities Act of 1933 would be available, no registration under the Securities Act will be required for the issuance of the Conversion Shares in the manner contemplated by the Notes, respectively.

We do not know of any contract or other document of a character required to be filed as an SEC Document which is not filed as required.

The SEC Documents incorporated by reference in the Confidential Private Placement Memorandum, on the respective dates they were filed, appeared on their face to comply in all material respects with the requirements as to form for reports on Form 10-K, Form 10-Q, Form 8-K and Schedule 14-A, except that we express no opinion concerning the financial statements and other financial or statistical information contained or incorporated by reference therein or the exhibits thereto.

In the course of acting as counsel for the Company in connection with the preparation by the Company of the Confidential Private Placement Memorandum, we have participated in conferences with officers and representatives of the Company, the independent accountants of the Company, and representatives of the Placement Agents and their counsel, at which time the contents of the Confidential Private Placement Memorandum and related matters were discussed. Although we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Confidential Private Placement Memorandum, based on such participation, no facts have come to our attention that would lead us to believe that the Confidential Private Placement Memorandum (except that we express no view with respect to the financial statements, including the notes thereto, and schedules or other financial data included therein or the exhibits contained in the SEC Documents) as of the date thereof contained any 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.
