Item 1.01.              Entry Into a Material Definitive Agreement

Effective February 9, 2005, the Registrant sold $40,000,000 of 7% Convertible Senior Subordinated Notes due 2025 (the “Notes”) in a private placement. The securities were sold to accredited investors in reliance on Regulation D under the Securities Act of 1933, as amended (the “Securities Act”). Attached hereto as Exhibits are conformed copies of the related definitive agreements – the Securities Purchase Agreement, the Registration Rights Agreement, the Indenture, the Form of Note, the Fourth Amendment to our Credit Agreement and the press release announcing the private placement.

The Securities

The private placement consists of $40,000,000 of 7% Convertible Senior Subordinated Notes due 2025.

Maturity Date/Interest Payment Dates

The Notes have a final maturity date of February 15, 2025.  Interest is payable semi-annually on February 15 and August 15 of each year, beginning on August 15, 2005.

Conversion at Holder’s Option

The Notes are convertible at the option of the holder at any time prior to maturity into shares of our common stock, initially at a conversion price of $25.90 per share (which was 140% of the $18.50 closing price for our common stock on February 8, 2005 on The NASDAQ Stock Market).  If fully converted, the Notes would convert into 1,544,402 shares of the Company’s common stock.

As required by the Indenture under which we issued the Notes, we reserved 1,621,622 shares of our common stock for issuance on conversion of the Notes (representing 105% of the number of shares of our common stock into which the Notes currently are convertible).

If a Note holder elects to convert a note prior to February 15, 2008 in connection with certain corporate change of control transactions in which 10% or more of the consideration for our common stock consists of cash, securities or other property that is not traded or scheduled to be traded immediately following such transaction on a U.S. national securities exchange or the NASDAQ National Market, we will increase the conversion rate for the Notes surrendered for conversion by a number of additional shares as described in the Indenture.

The conversion price of the Notes also will be subject to adjustment as described in the Indenture under certain other circumstances, including subdivision of our common stock or distributions on our common stock in the form of our common stock, other rights or warrants to acquire our common stock, or other shares of our capital stock, or cash distributions on our common stock in excess of $0.36 per share in any year.

Automatic Conversion

At any time prior to maturity, subject to certain conditions in the Indenture, we may elect to automatically convert the Notes into shares of our common stock at the then effective conversion price if the closing price of our common stock exceeds 150% of the then effective conversion price for at least 20 consecutive trading days during any 30 day period ending within 30 days prior to our notice of automatic conversion. If we effect an automatic conversion of the Notes prior to February 15, 2008, we will make

2

an additional payment equal to three full years of interest, less any interest actually paid or provided for prior to the conversion date.  We may pay this additional payment in cash or, at our option, in shares of our common stock.  If we elect to pay the additional payment in our common stock, we will value our common stock at 95% of the closing price of our common stock for the five trading days ending on and including the second trading day immediately preceding the conversion date.

Optional Redemption

At any time on or after February 20, 2008, subject to certain conditions in the Indenture, we may redeem some or all of the Notes at 100% of the principal amount plus accrued and unpaid interest to, but excluding, the redemption date.

Repurchase at Holder’s Option upon Certain Dates and Events

A holder of Notes may require us to repurchase such holder’s Notes in cash at a price equal to 100% of the principal amount of those Notes plus accrued and unpaid interest, if any, to the applicable repurchase date:

•on February 15, 2010, February 15, 2015 or February 15, 2020; or

•upon a change in control event or if our common stock is no longer authorized for quotation or listing on any of The New York Stock Exchange, Inc., the American Stock Exchange, Inc. or The NASDAQ National Market.

Subordination

The Notes are unsecured senior subordinated obligations and are subordinated in right of payment to any existing and future senior indebtedness (including indebtedness under our Credit Agreement).  As of December 31, 2004, we had approximately $44.1 million in senior indebtedness outstanding. We and our subsidiaries are not prohibited from incurring senior indebtedness or other debt under the terms of the Notes and the Indenture.

Registration Rights

The Notes and our common stock issuable upon conversion of the Notes have not been registered under the Securities Act or the securities laws of any jurisdiction, and these securities may not be offered or sold in the United States or any other jurisdiction where such registration is required and has not been effected, except in a transaction not subject to, or exempt from the registration requirements of the Securities Act and any other applicable securities laws.

Pursuant to a Registration Rights Agreement we have agreed to file with the Securities and Exchange Commission a shelf registration statement covering the resale of the Notes and our common stock issuable upon conversion of the Notes on or prior to March 11, 2005 and to use best efforts to cause the shelf registration statement to become effective within 90 days of such date, or within 120 days of such date if the filing is reviewed by the Securities and Exchange Commission. We will be required to pay certain “registration delay payments” as described in the registration rights agreement if these deadlines are not met or the shelf registration statement is otherwise unavailable for the resale of the securities.

3

Use of Proceeds

We have used the proceeds to repay the term loan under our Credit Agreement in full and pay down the revolving loan under our Credit Agreement, which will create availability for working capital and capital expenditures.  Upon completion of this transaction, the outstanding amount against the revolving loan will be approximately $7 million.

Amendment of our Credit Agreement

In connection with the private placement, as described in this Form 8-K, we entered into a Fourth Amendment to our Credit Agreement effective February 9, 2005 to permit the sale of the Notes. We intend to renegotiate our bank credit arrangement on more favorable terms to provide additional financial flexibility.

The Notes shall be issuable in registered form without coupons in denominations of One Thousand United States Dollars ($1,000) principal amount and integral multiples thereof.  Every Note shall be dated the date of its authentication, and shall bear interest on the principal sum outstanding from time to time under the Note, at the rate per annum specified in the title of the form of Note attached as Exhibit A hereto, accrued from the date of issuance of the Note and payable semi-annually on February 15 and August 15 of each year (each, an “Interest Payment Date”), commencing August 15, 2005, as specified on the face of the form of Note attached as Exhibit A hereto.

Interest on the Notes shall be deemed to have commenced accruing on February 9, 2005.

The Person in whose name any Note, or portion thereof (or its Predecessor Note) is registered at the close of business on any record date with respect to any Interest Payment Date (including any Note that is converted after the record date and on or before the Interest Payment Date) shall be entitled to receive the interest payable on such Interest Payment Date notwithstanding the cancellation of such Note upon any transfer, exchange or conversion subsequent to the record date and on or prior to such Interest Payment Date; provided that, in the case of any Note, or portion thereof, called for redemption or converted pursuant to Article III or Article XV on a redemption date or conversion date, as applicable, or repurchased by the Company pursuant to Article XVI on a Repurchase Date, during the period from the close of business on the record date to the close of business on the Business Day next preceding the following Interest Payment Date, interest shall not be paid to the Person in whose name the Note, or portion thereof, is registered on the close of business on such record date, and the Company shall have no obligation to pay interest on such Note or portion thereof except to the extent required to be paid upon such redemption, conversion or repurchase in accordance with Article III, Article XV or Article XVI.  Interest may, at the option of the Company, be paid by check mailed to the address of such Person on the Note Register; provided that, with respect to any holder of Notes with an aggregate principal amount equal to or in excess of Five Hundred Thousand United States Dollars ($500,000), interest on such holder’s Notes shall be paid by wire transfer in immediately available funds to any bank located in the United States in accordance with the wire transfer instruction supplied by such holder from time to time to the Trustee and paying agent (if different from Trustee) at least five (5) Business Days prior to the applicable record date.  The term “record date” with respect to any Interest Payment Date shall mean the 4th day of the month in which the Interest Payment Date shall occur, whether or not such date is a Business Day.  Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.  Any accrued and unpaid interest which is not paid within five (5) Business Days of the Interest Payment Date on which such payment of interest was due shall bear interest at the rate of 12% per annum from such Interest Payment Date until the same is paid in full (or, if less, the maximum interest rate then permitted by applicable law) (the “Default Interest”).

11

in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment.  The Company shall fix or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than ten (10) days prior to the related payment date for such defaulted interest.  At least fifteen (15) days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall send or cause to be sent to holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.4Execution of Notes

The Notes shall be signed in the name and on behalf of the Company by the facsimile signature of its President, its Chief Executive Officer, or any of its Vice Presidents, and attested by the facsimile signature of its Chief Financial Officer, Treasurer or its Assistant Treasurer, or Secretary or any of its Assistant Secretaries (which may be printed, engraved or otherwise reproduced thereon, by facsimile or otherwise).  Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose.  Such certificate by the Trustee (or such authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder thereof is entitled to the benefits of this Indenture.

In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an officer.

23

The Company may, but is not obligated to, instruct the transfer agent for the Company’s Common Stock 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 SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY THE SECURITIES.

Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.5(h)(ii).

(iii)Global Note Legend.  Each Global Note shall bear a legend in substantially the following form:

THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.6 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.5(b) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.8 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

(i)Resale of Notes Purchased by the Company or an Affiliate.  Any Note or Common Stock issued upon the conversion or exchange of a Note that, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor rule), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered

24

under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144).

(j)Changes in Law.  Notwithstanding any provision of Section 2.5 to the contrary, in the event Rule 144(k) as promulgated under the Securities Act (or any successor rule) is amended to change the two-year period under Rule 144(k) (or the corresponding period under any successor rule), from and after receipt by the Trustee of the Officer’s Certificate and Opinion of Counsel provided for in this Section 2.5(j), (i) each reference in Section 2.5(h)(i) to “two (2) years” shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 2.5(h)(ii) to “two (2) years” shall be deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Notes shall be deemed for all purposes hereof to be references to such changed period, 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.  As soon as practicable after the Company has knowledge of the effectiveness of any such amendment to change the two-year period under Rule 144(k) (or the corresponding period under any successor rule), unless such changes would otherwise be prohibited by, or would otherwise cause a violation of, the then-applicable securities law, the Company shall provide to the Trustee an Officer’s Certificate and Opinion of Counsel informing the Trustee of the effectiveness of such amendment and the effectiveness of the foregoing changes to Sections 2.5(h)(i) and 2.5(h)(ii) and the Notes.  The provisions of this Section 2.5(j) will not be effective until such time as the Opinion of Counsel and Officer’s Certificate have been received by the Trustee hereunder.  This Section 2.5(j) shall apply to successive amendments to Rule 144(k) (or any successor rule) changing the holding period thereunder.

(k)Limitation on Trustee’s Duties.  The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(l)Cancellation and/or Adjustment of Global Notes.  At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.8.  At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the

25

Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

Section 2.6Mutilated, Destroyed, Lost or Stolen Notes

In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen.  In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their reasonable satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may reasonably require.  Upon the issuance of any substituted Note, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith.  Once any substitute Note has been issued pursuant to this Section 2.6, the original Note being replaced by such substitute Note shall automatically be deemed canceled.  In case any Note which has matured or is about to mature or has been called for redemption or is about to be converted into Common Stock shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as will be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in case of destruction, loss or theft, evidence reasonably satisfactory to the Company, the Trustee and, if applicable, any paying agent or conversion agent of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder.  To the extent permitted by law, all Notes shall be held and owned upon the express condition that

26

the foregoing provisions are exclusive with respect to the replacement or payment or conversion of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender.

Section 2.7Temporary Notes

Pending the preparation of definitive Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed).  Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Global Notes or the Definitive Notes, as the case may be, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company.  Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Definitive Notes or Global Notes.  Without unreasonable delay the Company will execute and deliver to the Trustee or such authenticating agent Definitive Notes and Global Notes and thereupon any or all temporary Notes may be surrendered in exchange for the applicable replacement Note, at each office or agency maintained by the Company pursuant to Section 5.2 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Definitive Notes or Global Notes, as the case may be.  Such exchange shall be made by the Company at its own expense and without any charge therefor.  Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Definitive Notes or Global Notes, as the case may be, authenticated and delivered hereunder.

Section 2.8Cancellation of Notes Paid, Etc.

All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any paying agent or any Note Registrar or any conversion agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture.  Upon written instructions of the Company, the Trustee shall dispose of canceled Notes in accordance with its customary procedures.  If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

Section 2.9CUSIP Numbers

The Company in issuing the Notes shall use “CUSIP” numbers  and the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption

27

shall not be affected by any defect in or omission of such numbers.  The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE III

OPTIONAL REDEMPTION OF NOTES

Section 3.1Redemption Price

At any time on or after February 20, 2008, the Company may, at its option, redeem all or any part of the Notes, upon notice as set forth in Section 3.2, and the Company shall pay each holder of Notes redeemed a redemption price equal to the principal amount of such Notes, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption; provided that, to the extent that the Shelf Registration Statement is required by the terms of the Registration Rights Agreement to remain effective as of the date that notice of redemption is provided in accordance with Section 3.2, the Shelf Registration Statement is effective and available during the 30 day period prior to the giving of such notice and at all times from the date of such notice until the redemption date; provided, further that prior to February 20, 2010, in the event that the Common Stock is not listed or approved for listing on the NYSE, AMEX or NASDAQ, the Company may only exercise its redemption right under this Section 3.1 if the Closing Price during the 30 day period prior to the giving of such notice and at all times from the date of such notice until the redemption date was less than 95% of the Conversion Price in effect on each such day.

The Company’s right to require a redemption pursuant to Section 3.1 shall not be exercised by the Company more than three times.

Section 3.2Notice of Redemption; Selection of Notes

In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.1, it shall fix a date for redemption, and it, or at its request (which must be received by the Trustee at least ten (10) Business Days prior to the date the Trustee is requested to give notice as described below unless a shorter period is agreed to by the Trustee), the Trustee in the name of and at the expense of the Company, shall send or cause to be sent a notice of such redemption at least twenty (20) and not more than ninety (90) days prior to the date fixed for redemption (such date, the “Redemption Date”) to the holders of Notes so to be redeemed as a whole or in part at their last addresses as the same appear on the Note Register (provided that if the Company shall give such notice, it shall also give such notice, and notice of the aggregate amount of Notes to be redeemed, to the Trustee).  Such notice shall be irrevocable.  The notice if sent in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the holder receives such notice.  In any case, failure to give such notice or any defect in the notice to the holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

28

Each such notice of redemption shall specify the aggregate principal amount of Notes to be redeemed, the “CUSIP” number or numbers of such Notes, the Redemption Date, the redemption price at which Notes are to be redeemed, the place or places of payment, that payment will be made upon presentation and surrender of such Notes, that interest accrued to, but excluding, the Redemption Date will be paid as specified in said notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue.  Such notice shall also state the current Conversion Price and the date on which the right to convert such Notes or portions thereof into Common Stock will expire, which shall be the close of business on the Redemption Date.  If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed.  In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued.

On or prior to the Redemption Date, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 5.4) an amount of money sufficient to redeem on the redemption date all the Notes (or portions thereof) so called for redemption (other than those theretofore surrendered for conversion into Common Stock) at the appropriate redemption price, together with accrued interest to, but excluding, the Redemption Date; provided that if such payment is made on the Redemption Date it must be received by the Trustee or paying agent, as the case may be, by 1:00 p.m. New York City time, on such date.  If any Note called for redemption is converted pursuant hereto, any money deposited with the Trustee or any paying agent or so segregated and held in trust for the redemption of such Note shall be paid to the Company upon its request, or, if then held by the Company shall be discharged from such trust.

If fewer than all the Notes are to be redeemed, the Company will give the Trustee written notice in the form of an Officer’s Certificate not fewer than forty-five (45) days (or such shorter period of time as may be acceptable to the Trustee) prior to the Redemption Date as to the aggregate principal amount of Notes to be redeemed, and the Company, or at its request, the Trustee in the name of and at the expense of the Company, shall give the holders at least twenty (20) days’ notice in advance of the Redemption Date as to the aggregate principal amount of Notes to be redeemed.  If fewer than all the Notes are to be redeemed, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of One Thousand United States Dollars ($1,000) or integral multiples thereof), on a pro rata basis or by lot.  If any Note selected for partial redemption is converted in part after such selection, the converted portion of such Note shall be deemed (so far as is possible) to be the portion to be selected for redemption.  The Notes (or portions thereof) so selected shall be deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is converted as a whole or in part before the sending of the notice of redemption.

Upon any redemption of less than all Notes, the Company and the Trustee may (but need not) treat as outstanding any Notes surrendered for conversion during the period of fifteen (15) days next preceding the sending of a notice of redemption and may (but need not) treat as not outstanding any Note authenticated and delivered during such period in exchange for the unconverted portion of any Note converted in part during such period.

29

Section 3.3Payment of Notes Called for Redemption

If notice of redemption has been given as above provided, the Notes or portion of Notes with respect to which such notice has been given shall, unless converted into Common Stock pursuant to the terms hereof, become due and payable on the date and at the place or places stated in such notice at the applicable redemption price, and interest accrued to, but excluding, the Redemption Date, and on and after said date (unless the Company shall default in the payment of such Notes at the redemption price and interest accrued to, but excluding, said date) interest on the Notes or portion of Notes so called for redemption shall cease to accrue and such Notes shall cease at the close of business on the Redemption Date to be convertible into Common Stock and, except as provided in Sections 8.5 and 13.4, to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Notes except the right to receive the redemption price thereof and unpaid interest to, but excluding, the Redemption Date.  On presentation and surrender of such Notes at a place of payment specified in said notice, the said Notes or the specified portions thereof to be redeemed shall be paid and redeemed by the Company at the applicable redemption price and interest accrued thereon to, but excluding, the Redemption Date; provided that, if the applicable Redemption Date is an Interest Payment Date, the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3.

Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and deliver to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

Notwithstanding the foregoing, the Trustee shall not redeem any Notes or send any notice of optional redemption during the continuance of a default in payment of interest or premium on the Notes or of any Event of Default of which, in the case of any Event of Default other than under Section 7.1(a), a Responsible Officer of the Trustee has actual knowledge.  If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate borne by the Note and such Note shall remain convertible into Common Stock until the principal and premium, if any, shall have been paid or duly provided for.

Section 3.4Conversion Arrangement on Call for Redemption

In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes not converted prior to the expiration of such conversion right by an agreement with one or more investment bankers or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable redemption price and interest accrued to the date fixed for redemption, of such Notes.  Notwithstanding anything to the contrary contained in this Article III, the obligation of the Company to pay the redemption price of such Notes and interest accrued to, but excluding, the date fixed for redemption, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers to such Noteholders.  If such

30

an agreement is entered into, a copy of which, certified as true and correct by the Secretary or Assistant Secretary of the Company will be filed with the Trustee prior to the date fixed for redemption, any Notes not duly surrendered for conversion by the holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such holders and (notwithstanding anything to the contrary contained in Article XV) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the date fixed for redemption (and the right to convert any such Notes shall be deemed to have been extended through such time), subject to payment of the above amount as aforesaid.  At the written direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes.  Without the Trustee’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Notes between the Company and such purchasers, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture.

Indebtedness to receive payments or distributions of the assets of the Company made on such Senior Indebtedness until all principal and interest on the Notes shall be paid in full; and for purposes of such subrogation, no payments or distributions to the holders of Senior Indebtedness of any cash, property or securities to which any holders of the Notes would be entitled except for the subordination provisions of this Article IV shall, as between the holders of the Notes and the Company and/or its creditors other than the holders of the Senior Indebtedness, be deemed to be a payment on account of the Senior Indebtedness.

Section 4.7Rights of Holders Unimpaired

The provisions of this Article IV are and are intended solely for the purposes of defining the relative rights of the holders of the Notes and the holders of Senior Indebtedness and nothing in this Article IV shall impair, as between the Company and any holders of the Notes, the obligation of the Company, which is unconditional and absolute, to pay to the holders of the Notes the principal thereof (and premium, if any) and interest thereon, in accordance with the terms of the Notes.

Section 4.8Holders of Senior Indebtedness

These provisions regarding subordination will constitute a continuing offer to all Persons who, in reliance upon such provisions, become holders of, or continue to hold, Senior Indebtedness; such provisions are made for the benefit of the holders of Senior Indebtedness, and such holders are hereby made obligees under such provisions to the same extent as if they were named therein, and they or any of them may proceed to enforce such subordination and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders have agreed in writing thereto.  The holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to any of the Noteholders, without incurring responsibility to the Noteholders and without impairing or releasing the subordination provisions of this Article IV, (i) increase the amount of, change the manner, terms or place of payment of, or renew or alter, any Senior Indebtedness, or otherwise amend, modify, restate or supplement the same, (ii) sell, exchange or release any collateral mortgaged, pledged or otherwise securing the Senior Indebtedness, (iii) release any Person liable in any manner for the Senior Indebtedness and (iv) exercise or refrain from exercising any rights against the Company or any other Person.

Section 4.10Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee’s Rights

The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article IV with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.6.

Section 4.13Prior Notice of Acceleration.

The holders of the Notes agree, solely for the benefit of the lenders under the Senior Facility, not to declare the unpaid principal amount of any Note to be due and payable pursuant to Section 7.1 unless the Representative of the Senior Facility shall have received not less than five (5) Business Days’ prior written notice from the Company, the Trustee or any holder of the Notes of such declaration of acceleration.  The Company, forthwith upon receipt of any such declaration of acceleration, shall send a copy thereof to the Representative of the Senior Facility.

44

Trustee by the holders of not less than 20% in aggregate principal amount of the Notes then outstanding, a written notice specifying such default and requiring the Company to cause such default to be cured or waived and stating that such notice is a “Notice of Default” hereunder;

then, and in each and every such case (other than an Event of Default specified in Section 7.1(e) or (f) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, and unless the Event of Default shall have been waived in writing in accordance with the provisions of Section 7.7, either the Trustee or the holders of not less than 20% in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with Section 9.4, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of and premium, if any, on all the Notes and the interest accrued thereon (including Liquidated Damages to the extent accrued and unpaid) to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding.  If an Event of Default specified in Section 7.1(e) or (f) occurs and is continuing with respect to the Company, the principal of all the Notes and the interest accrued thereon (including Liquidated Damages to the extent accrued and unpaid) shall be immediately due and payable.  In addition to the foregoing, upon an Event of Default, the rate of interest on the Notes shall, be increased by five percent (5%) per annum (i.e., from 7% to 12% per annum), or if less, increased to the maximum interest rate then permitted by applicable law.  Any such interest which is not paid when due shall, to the maximum extent permitted by law, accrue interest until paid at the rate from time to time applicable to the interest on the Notes.  Notwithstanding the foregoing if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all Notes and the principal of and premium, if any, on any and all Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest (to the extent that payment of such interest is enforceable under applicable law) and on such principal and premium, if any, at the rate borne by the Notes, to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 8.6, and if any and all defaults under this Indenture, other than the nonpayment of principal of and premium, if any, and accrued interest on Notes which shall have become due by acceleration, shall have been cured or waived pursuant to Section 7.7, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and annul such acceleration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon.  The Company shall notify the Responsible Officer of the Trustee, within three (3) Business Days of becoming aware thereof, of any default or Event of Default and shall deliver to the Trustee a statement specifying such default or Event of Default and the action the Company has taken, is taking or proposes to take with respect thereto.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or

45

rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding had been instituted.

Section 7.2Payments of Notes on Default; Suit Therefor

The Company covenants that (a) in case default shall be made in the payment by the Company of any installment of interest upon any of the Notes as and when the same shall become due and payable, and such default shall have continued for a period of thirty (30) days, or (b) in case default shall be made in the payment of the principal of or premium, if any, on any of the Notes as and when the same shall have become due and payable, whether at maturity of the Notes or in connection with any redemption or repurchase, by declaration under this Indenture or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then shall have become due and payable on all such Notes for principal and premium, if any, or interest, or both, as the case may be, with interest upon the overdue principal and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Notes; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and any expenses or liabilities incurred by the Trustee hereunder other than through its negligence or bad faith.  Until such demand by the Trustee, the Company may pay the principal of and premium, if any, and interest on the Notes to the registered holders, whether or not the Notes are overdue.

In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.2, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest (including Liquidated Damages, if any) owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may

46

deem necessary or advisable in order to have the claims of the Trustee and of the Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 8.6; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees incurred by it up to the date of such distribution.  To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof on any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings.

Section 7.3Application of Monies Collected by Trustee

Any monies collected by the Trustee pursuant to this Article VII shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First:To the payment of all amounts due the Trustee under Section 8.6;

Second:To the payment of all Senior Indebtedness to the extent required by Article IV;

Third:In case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest

Fifth:To the payment of the remainder, if any, to the Company.

Section 7.4Proceedings by Noteholder

Subject to the last two paragraphs of this Section 7.4, no holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than 20% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such indemnity as may be reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 7.7; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Notes (except as otherwise provided herein).  For the protection and enforcement of this Section 7.4, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any holder of any Note to receive payment of the principal of and premium, if any, and interest (including Liquidated Damages to the extent accrued but unpaid) on such Note, on or after the respective due dates expressed in such Note, or to institute suit for the enforcement of

48

any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such holder.

Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in his own behalf and for his own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, such holder’s rights of conversion as provided herein.

Section 7.5Proceedings by Trustee

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 7.6Remedies Cumulative and Continuing

Except as provided in the last paragraph of Section 2.6, all powers and remedies given by this Article VII to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein; and, subject to the provisions of Section 7.4, every power and remedy given by this Article VII or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

Section 7.7Direction of Proceedings and Waiver of Defaults by Majority of Noteholders

The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.4 shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.  The holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.4 may on behalf of the holders of all of the Notes waive any past default or Event of Default hereunder and its consequences except (i) a default in the payment of interest or premium, if any, on, or the principal of, the Notes when due,

49

(ii) a failure by the Company to convert any Notes into Common Stock or (iii) a default in respect of a covenant or provisions hereof which under Article XI cannot be modified or amended without the consent of all affected holders of Notes then outstanding.  Upon any such waiver the Company, the Trustee and the holders of the Notes shall be restored to their former positions and rights hereunder; said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

Section 7.8Notice of Defaults

The Trustee shall, within ninety (90) days after the Trustee obtains knowledge of the occurrence of a default, send to all Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of all defaults actually known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; and provided that, except in the case of default in the payment of the principal of, or premium, if any, or interest (including Liquidated Damages to the extent accrued but unpaid) on any of the Notes, including without limiting the generality of the foregoing any default in the payment of any Repurchase Price or in the payment of any amount due in connection with any redemption of Notes, then in any such event the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders.

Section 7.9Undertaking to Pay Costs

All parties to this Indenture agree, and each holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 7.9 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 20% in principal amount of the Notes at the time outstanding determined in accordance with Section 9.4, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or premium, if any, or interest (including Liquidated Damages to the extent accrued but unpaid) on any Note (including, but not limited to, the redemption price or Repurchase Price with respect to the Notes being redeemed or repurchased as provided in this Indenture) on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article XV.

Section 7.10Delay or Omission Not Waiver

No delay or omission of the Trustee or of any holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a

50

waiver of any such Event of Default or any acquiescence therein.  Every right and remedy given by this Article VII or by law to the Trustee or to the holders of Notes may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the holders of Notes, as the case may be.

ARTICLE VIII

CONCERNING THE TRUSTEE

Section 8.1Duties and Responsibilities of Trustee

The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and the Trust Indenture Act.  In case an Event of Default has occurred (which has not been cured or waived) the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that

(a)prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

(1)the duties and obligations of the Trustee shall be determined solely by the Trust Indenture Act and the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and

(2)in the absence of bad faith or willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

(b)the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

51

(c)the Trustee shall not be liable to any Noteholder with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of not less than a majority in principal amount of the Notes at the time outstanding determined as provided in Section 9.4 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

(d)whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Section 8.2Reliance on Documents, Opinions, Etc.

Except as otherwise provided in Section 8.1:

(a)the Trustee may conclusively rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, note, coupon or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

(b)any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be herein specifically prescribed) and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company;

(d)the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby;

(e)the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the

52

Trustee, in its reasonable discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require indemnity reasonably satisfactory to the Trustee from the Noteholders against such expenses or liability as a condition to so proceeding; the reasonable expenses of every such examination shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand;

(i)the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder;

In no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

Section 8.3No Responsibility for Recitals, Etc.

The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no

53

responsibility for the correctness of the same.  The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes.  The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture.

Section 8.5Monies to be Held in Trust

Subject to the provisions of Section 13.4, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received.  Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law.  The Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee.

Section 8.6Compensation and Expenses of Trustee

The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence, willful misconduct or bad faith.  The Company also covenants to indemnify the Trustee or any predecessor Trustee in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any and all loss, damages, claims, liability or expense, including taxes (other than those based upon, measured by or determined by the income of the Trustee), incurred without negligence, willful misconduct or bad faith on the part of the Trustee or such agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim (whether asserted by the Company, a holder or any other Person) of liability in the premises.  The obligations of the Company under this Section 8.6 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien upon all property and funds held or collected by the Trustee as such, except, subject to the effect of Sections 4.3 and 7.5, funds held in trust herewith for the benefit of the holders of particular Notes prior to the date of the accrual of such unpaid compensation or indemnifiable claim.  The obligation of the Company

54

under this Section 8.6 shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.  The indemnification provided in this Section 8.6 shall extend to the officers, directors, agents and employees of the Trustee.

When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 7.1(e) or (f) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

55

trustee.  If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the sending of such notice of resignation to the Noteholders, the resigning Trustee may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions of Section 7.9, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee.  Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b)In case at any time any of the following shall occur:

(1)the Trustee shall fail to comply with Section 8.8 within a reasonable time after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months, or

(2)the Trustee shall cease to be eligible in accordance with the provisions of Section 8.9 and shall fail to resign after written request therefor by the Company or by any such Noteholder, or

(3)the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.9, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.  Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c)The holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless within ten (10) days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Noteholder, upon the terms and conditions and otherwise as in Section 8.10(a) provided, may, at the expense of the Company, petition any court of competent jurisdiction for an appointment of a successor trustee.

(d)Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11.

56

(e)If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within thirty (30) days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

Section 8.11Acceptance by Successor Trustee

Any successor trustee appointed as provided in Section 8.10 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.6, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act.  Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers.  Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 8.6.

No successor trustee shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 8.8 and be eligible under the provisions of Section 8.9.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, the Company shall send or cause to be sent notice of the succession of such trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note Register.  If the Company fails to send such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be sent at the expense of the Company.

Section 8.12Succession by Merger, Etc.

Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee such corporation shall be qualified under the provisions of Section 8.8 and eligible under the provisions of Section 8.9.

57

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 8.13Limitation on Rights of Trustee as Creditor

If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor).

Section 12.2Successor Entity to be Substituted

In case of any such consolidation, merger, sale, conveyance or lease in accordance with Section 12.1, and, where required in accordance with Section 12.1(a) upon the assumption by the

CONVERSION OF NOTES

Section 15.1Right to Convert

Subject to and upon compliance with the provisions of this Indenture, the holder of any Note shall have the right, at the holder’s option, at any time following the date of original issuance of the Notes and prior to the close of business on February 15, 2025 (except that, with respect to any Note or portion of a Note that shall be called for redemption or automatic conversion, such right shall terminate, except as provided in the fifth paragraph of Section 15.2 and Section 3.4, at the close of business on the last Business Day prior to the date fixed for redemption or automatic conversion, as applicable, of such Note or portion of a Note unless the Company shall default in payment due upon redemption or automatic conversion thereof, as

69

applicable), to convert the principal amount of any such Note, or any portion of such principal amount which is One Thousand United States Dollars ($1,000) or an integral multiple thereof, into that number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing the principal amount of the Note or portion thereof surrendered for conversion by the Conversion Price in effect at such time in the manner provided in Section 15.2.  A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article XV.  A Note with respect to which a holder has delivered a notice in accordance with Section 16.2 regarding such holder’s election to require the Company to repurchase such holder’s Notes following the occurrence of a Repurchase Event may be converted in accordance with this Article XV only if such holder withdraws such repurchase notice by delivering a written notice of withdrawal to the Company prior to the close of business on the last Business Day prior to the day fixed for repurchase.

Section 15.2Exercise of Conversion Privilege; Issuance of Common Stock on Conversion

In order to exercise the conversion privilege with respect to any Definitive Note, the holder of such Definitive Note then registered on the books of the Company shall (i) deliver a written notice, in the form of the conversion notice attached hereto as Exhibit B, or a facsimile thereof (the “Conversion Notice”), to the Trustee, the Company (with a copy to the Company’s legal counsel) and the transfer agent at Equiserve Trust Company, N.A., 1 North State Street, 11^th Floor, Chicago, Illinois 60602, telephone (312) 499-7032, facsimile (312) 499-7065, Attention: Tammie Marshall, of such holder’s election to convert, which notice shall specify that all of such Note shall be converted or the portion thereof to be converted (which shall be One Thousand United States Dollars ($1,000) or an integral multiple thereof) and the name or names (with address) in which the shares of Common Stock which shall be issuable on such conversion shall be issued, (ii) if such Note or portion thereof is surrendered for conversion during the period from the close of business on the Business Day preceding the record date for any Interest Payment Date through the close of business on the Business Day next preceding such Interest Payment Date, pay by wire transfer of immediately available funds or other method acceptable to the Company, an amount equal to the interest otherwise payable on such Interest Payment Date on the principal amount being converted (unless such Note or portion thereof being converted shall have been called for redemption pursuant to a redemption notice sent to the Noteholders in accordance with Section 3.2 or shall have become due prior to such Interest Payment Date as a result of exercise of the repurchase right set forth in Article XVI); provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Notes,  (iii) pay by wire transfer of immediately available funds or other method acceptable to the Company the transfer taxes, if any, required pursuant to Section 15.7, and (iv) surrender the Definitive Note to be converted in whole or in part to a common carrier for overnight delivery to the Company as soon as practicable following such date (or an indemnification undertaking or other form of security reasonably satisfactory to the Company with respect to the Definitive Note in the case of its loss, theft or destruction).  Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and a Participant’s interest in a Global Note may be surrendered for conversion in

70

accordance with the Applicable Procedures as in effect from time to time.  Each Note surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Note, be duly endorsed by, or be accompanied by instruments of transfer (including a broker’s letter regarding compliance with the prospectus delivery requirement, if applicable) in form satisfactory to the Company duly executed by, the holder or his duly authorized attorney.

The Company shall use its best efforts to, within three (3) Business Days after the Conversion Date (as defined below) with respect to any Note, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Noteholder (as if such transfer were a transfer of the Note or Notes (or portion thereof) so converted) (a)(i) in the case of a resale of the Common Stock issuable upon such conversion, at the holder’s request, credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder’s or its designee’s balance account with The Depository Trust Company through its Deposit Withdrawal Agent Commission system or (ii) issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the holder or its designee, for the number of full shares of Common Stock to which the holder shall be entitled upon such conversion, and (b) deliver to such holder a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, as provided in Section 15.4 (which payment, if any, shall be paid no later than five (5) Business Days after the Conversion Date).  In case any Note of a denomination greater than One Thousand United States Dollars ($1,000) shall be surrendered for partial conversion, and subject to Section 2.3, the Company shall execute and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to him, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

Subject to Article IV, if the Company shall not have delivered the number of shares of Common Stock issued upon conversion of Notes by any holder within five (5) Business Days after the Conversion Date with respect to such Notes, the Company shall pay Liquidated Damages to such holder at the rate of one-half percent (0.5%) per month of the outstanding principal amount of Notes so converted by such holder.

The conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in this Section 15.2 have been satisfied as to such Note (or portion thereof) (such date, the “Conversion Date”), and the Person in whose name any shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on the Conversion Date the holder of record of the shares represented thereby; provided, however, that any such surrender on any date when the stock transfer books of the Company shall be closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Note shall be surrendered.  For purposes of determining satisfaction of the requirement set forth above with respect to the Conversion Date for any Note, any facsimile required to be sent shall be deemed to have been sent on a given day if such facsimile was received before 1:00 p.m., New York City time, on such date, to the number listed above (unless

71

a different number is specified in a notice filed with the Trustee and sent by the Trustee, at the Company’s expense, to each holder of the Notes at such holder’s address appearing in the Note Register, as provided for in Section 2.5 of this Indenture) and a confirmation of transmission of such facsimile is obtained.

The Company shall pay in cash, on any Note or portion thereof surrendered for conversion during the period from the close of business on any Interest Payment Date to which interest has been fully paid through the close of business on the Business Day preceding the record date for the next such Interest Payment Date, accrued and unpaid interest, if any, on the Note or portion thereof surrendered for conversion to, but excluding, the date of conversion, and Liquidated Damages, if any.  Subject to Article IV, any such payment of interest shall be made with respect to such Note within ten (10) Business Days after the Conversion Date.  Notwithstanding the foregoing, any Note or portion thereof surrendered for conversion during the period from the close of business on the record date for any Interest Payment Date through the close of business on the Business Day next preceding such Interest Payment Date shall (unless such Note or portion thereof being converted shall have been called for redemption pursuant to a redemption notice sent to the Noteholders in accordance with Section 3.2 or shall have become due prior to such Interest Payment Date as a result of exercise of the repurchase right set forth in Article XVI) be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest otherwise payable on such Interest Payment Date on the principal amount being converted; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Notes.  Nothing in this Section 15.2 shall affect the right of a holder in whose name any Note is registered at the close of business on a record date to receive the interest payable on such Note on the related Interest Payment Date in accordance with the terms of this Indenture and the Note.  Except as provided in this Section 15.2, no adjustment shall be made for interest accrued on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article.

Section 15.3Company Right to Force Automatic Conversion

The Company may, at its option, automatically convert all or a portion of the Notes (an “Automatic Conversion”) at any time prior to February 15, 2025 if the following conditions have been satisfied:

(a)the Closing Price (as defined in Section 15.6(e)) per share of the Common Stock has exceeded one hundred and fifty percent (150%) of the Conversion Price then in effect for at least twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days ending within the thirty (30) Trading Days prior to the date the Automatic Conversion Notice (defined below) specifying the date (the “Automatic Conversion Date”) on which an Automatic Conversion will become effective is sent to all holders of Notes;

(b)(i) the shares of Common Stock to be issued do not require registration or approval under any federal securities law before such shares may be freely transferable without being subject to any transfer restrictions under the Securities Act or such registration is completed or becomes effective prior to the delivery of the Automatic Conversion Notice and

72

such completion and effectiveness is maintained from after delivery of such Automatic Conversion Notice to the Automatic Conversion Date, (ii) the shares of Common Stock to be issued do not require registration or qualification under any state securities law before such shares may be validly issued or delivered or such registration or qualification is completed or becomes effective prior to the delivery of the Automatic Conversion Notice and such completion and effectiveness is maintained from after delivery of such Automatic Conversion Notice to the Automatic Conversion Date, and (iii) the issuance of the shares of Common Stock to be issued does not violate any Federal or state securities laws;

(c)the shares of Common Stock to be issued shall have been listed or approved for listing on the NYSE, AMEX, or NASDAQ, prior to the delivery of the Automatic Conversion Notice;

(d)the Company shall have sufficient authorized but unissued (or issued but not outstanding) shares of Common Stock (or, in the event of a merger, consolidation or other similar transaction involving the Company that is otherwise permitted under the terms of this Indenture in which the Company is not the surviving entity, out of the authorized but unissued Common Stock of the surviving entity or its direct or indirect parent entity) to issue the shares of Common Stock to be issued upon such conversion;

(e)the issuance of the shares of Common Stock to be issued does not require approval of the Company’s stockholders;

(f)the shares of Common Stock to be issued, upon issue, will be duly and validly issued and fully paid and nonassessable and free of any preemptive rights; and

(g)the Company is not prevented from making the Company Conversion Provisional Payment (as defined below) on the Automatic Conversion Date as a result of the provisions of Section 4.2.

Subject to Article IV, if the Automatic Conversion Date is prior to February 15, 2008, the Company shall make an additional payment to each holder of Notes with respect to the Notes converted, in an amount equal to $210 per each One Thousand United States Dollars ($1,000) principal amount of the Note (the “Company Conversion Provisional Payment”), less the amount of any interest actually paid on the portion of the principal amount of the Note to be converted prior to the Automatic Conversion Date (and, if the Note is converted between a record date and the next Interest Payment Date, less interest payable on each One Thousand United States Dollars ($1,000) principal amount of the Note on such next Interest Payment Date).

Unless the Company shall have theretofore called for redemption all of the Notes then outstanding, if the Company elects to convert all or a portion of the Notes pursuant to this Section 15.3, the Company, or at its request (which must be received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below unless a shorter period is agreed to by the Trustee), the Trustee in the name of and at the expense of the Company, shall send or cause to be sent a notice (the “Automatic Conversion Notice”) of the Automatic Conversion not more than thirty (30) days but not less than five (5) days before

73

the Automatic Conversion Date to such holders at their last addresses as they shall appear upon the Notes Register.  Such notice shall be irrevocable.  Any notice that is sent in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder receives the notice.  In any case, failure to duly give such notice to the holder of any Notes designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the automatic conversion of any other Notes.

Each Automatic Conversion Notice shall state:

(a)The Automatic Conversion Date,

(b)the CUSIP number(s) of the Note(s) to be automatically converted,

(c)the place or places where such Notes are to be surrendered for conversion,

(d)the Conversion Price then in effect,

(e)the amount of the Company Conversion Provisional Payment and

(f)the Additional Shares, if any, to be issued pursuant to Section 15.13.

In case the Notes are to be converted in part only, the Automatic Conversion Notice shall state the portion of the principal amount thereof to be converted and shall state that on and after the Automatic Conversion Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unconverted portion thereof will be issued.

If any of the foregoing provisions or other provisions of this Section are inconsistent with applicable law, such law shall govern.

In the event of an Automatic Conversion, the Company shall issue and deliver a certificate or certificates for the number of full shares of Common Stock issuable upon conversion of the Notes or, at the holder’s request, credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder’s balance account with the Depositary through its Deposit Withdrawal Agent Commission system, along with (i) any cash in respect of any fractional shares of Common Stock otherwise issuable upon conversion (as provided in Section 15.4), and (ii) the Company Conversion Provisional Payment, if any, for payment to the holder as promptly after the Automatic Conversion Date as practicable in accordance with the provisions of this Section 15.3.

All Notes subject to the Automatic Conversion shall be delivered to the Company to be canceled.  Failure to deliver such Notes shall not affect their automatic cancellation.

Section 15.4Cash Payments in Lieu of Fractional Shares

No fractional shares of Common Stock or scrip representing fractional shares shall be issued upon conversion of Notes.  If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares which shall be issuable upon conversion

74

thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered for conversion.  If any fractional share of stock otherwise would be issuable upon the conversion of any Note or Notes, the Company shall calculate and pay a cash adjustment in lieu of such fractional share at the current market value thereof to the holder of Notes.  For purposes of this Section 15.4, the current market value of a share of Common Stock shall be the Closing Price (determined as provided in Section 15.6(e)) on the first Trading Day immediately preceding the day on which the Notes (or specified portions thereof) are deemed to have been converted.

Section 15.5Conversion Price

The conversion price shall be as specified in the form of Note (herein called the “Conversion Price”) attached as Exhibit A hereto, subject to adjustment as provided in this Article XV.

Section 15.6Adjustment of Conversion Price

The Conversion Price shall be adjusted from time to time by the Company as follows:

(a)In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Price in effect at the opening of business on the date following the date fixed for the determination of shareholders entitled to receive such dividend or other distribution shall be reduced by multiplying such Conversion Price by a fraction of which (i) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the Record Date (as defined in Section 15.6(e)) fixed for such determination and (ii) the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction in the Conversion Price to become effective immediately after the opening of business on the day following the Record Date.  If any dividend or distribution of the type described in this Section 15.6(a) is declared but not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared.

(b)In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

75

(c)In case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price (as defined in Section 15.6(e)) on the Record Date fixed for the determination of shareholders entitled to receive such rights or warrants, the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect at the opening of business on the date after such Record Date by a fraction of which (i) the numerator shall be the sum of the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares that the aggregate offering price of the total number of shares so offered for subscription or purchase would purchase at such Current Market Price, and of which (ii) the denominator shall be the sum of the number of shares of Common Stock outstanding at the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for subscription or purchase.  Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of shareholders entitled to receive such rights or warrants.  To the extent that shares of Common Stock are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Price shall be readjusted to the Conversion Price that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered.  In the event that such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such date fixed for the determination of shareholders entitled to receive such rights or warrants had not been fixed.  In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors.

(d)In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 15.6(a) applies) or evidences of its indebtedness or other assets (including securities, but excluding (1) any rights or warrants referred to in Section 15.6(c) and (2) dividends and distributions paid exclusively in cash (except as set forth in Section 15.6(e), (the foregoing hereinafter in this Section 15.6(d) called the “Additional Securities”)), unless the Company elects to reserve such Additional Securities for distribution to the Noteholders upon conversion of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such Additional Securities which such holder would have received if such holder had converted its Notes into Common Stock immediately prior to the Record Date (as defined in Section 15.6(e)) for such distribution of the Additional Securities then, in each such case, the Conversion Price shall be reduced so that the same shall be equal to the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction of which (i)

76

the numerator shall be the Current Market Price (determined as provided in Section 15.6(e)) on such date less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) on such date of the portion of the Additional Securities so distributed applicable to one share of Common Stock and (ii) the denominator shall be such Current Market Price, such reduction to become effective immediately prior to the opening of business on the day following the Record Date; provided, however, that in the event the then fair market value (as so determined) of the portion of the Additional Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of Common Stock such holder would have received had such holder converted such Note (or portion thereof) immediately prior to such Record Date.  In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared.  If the Board of Directors determines the fair market value of any distribution for purposes of this Section 15.6(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 15.6(e) to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Noteholder.

In the event that the Company implements a new shareholder rights plan, such rights plan shall provide that upon conversion of the Notes the holders will receive, in addition to the Common Stock issuable upon such conversion, the rights issued under such rights plan as if the holders had converted the Notes prior to implementing the rights plan and notwithstanding the occurrence of an event causing such rights to separate from the Common Stock at or prior to the time of conversion.  Any distribution of rights or warrants pursuant to a shareholder rights plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants for the purposes of this Section 15.6(d).

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.6(d) (and no adjustment to the Conversion Price under this Section 15.6(d) will be required) until the occurrence of the earliest Trigger Event.  If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitles the holder to purchase a

77

different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof).  In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Price under this Section 15.6(d), (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants all of which shall have expired or been terminated without exercise, the Conversion Price shall be readjusted as if such rights and warrants had never been issued.

For purposes of this Section 15.6(d) and Sections 15.6(a) and (c), any dividend or distribution to which this Section 15.6(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 15.6(a) or 15.6(c) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock or rights or warrants to which Section 15.6(c) applies (and any Conversion Price reduction required by this Section 15.6(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Price reduction required by Sections 15.6(a) and (c) with respect to such dividend or distribution shall then be made, except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of shareholders entitled to receive such dividend or other distribution”, “Record Date fixed for such determination” and “Record Date” within the meaning of Section 15.6(a) and as “the date fixed for the determination of shareholders entitled to receive such rights or warrants”, “the Record Date fixed for the determination of the shareholders entitled to receive such rights or warrants” and “such Record Date” within the meaning of Section 15.6(c) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 15.6(a).

In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed upon a merger or consolidation to which Section 15.7 applies or as part of a distribution referred to in Section 15.6), then immediately after the close of business on the Record Date for the distribution, the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on such Record Date by a fraction (i) the numerator of which shall be equal to

78

the Current Market Price on the Record Date less an amount equal to the quotient of (x) such combined amount and (y) the number of shares of Common Stock outstanding on the Record Date and (ii) the denominator of which shall be equal to the Current Market Price on such date; provided, however, that in the event the portion of the cash so distributed applicable to one (1) share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of cash such holder would have received had such holder converted such Note (or portion thereof) immediately prior to such Record Date.  In the event that such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared. Notwithstanding anything to the contrary herein, the adjustment required by this paragraph shall not be required as a result of cash dividends paid by the Company in an aggregate amount equal to or less than $0.36 per share (appropriately adjusted for any share dividends on or subdivisions or combinations of the Common Stock) in any fiscal year of the Company.

(e)For purposes of this Section 15.6, the following terms shall have the meaning indicated:

(1) “Closing Price” with respect to any securities on any day shall mean the closing sale price regular way on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case on the Nasdaq National Market or New York Stock Exchange, as applicable, or, if such security is not listed or admitted to trading on such National Market or Exchange, on the principal national security exchange or quotation system on which such security is quoted or listed or admitted to trading, or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the National Quotation Bureau Incorporated, or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution.

(2) “Current Market Price” shall mean the average of the daily Closing Prices per share of Common Stock for the ten (10) consecutive Trading Days immediately prior to the date in question; provided, however, that (1) if the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.6(a), (b), (c) or (d) occurs during such ten (10) consecutive Trading Days, the Closing Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by multiplying such Closing Price by the same

79

fraction by which the Conversion Price is so required to be adjusted as a result of such other event, (2) if the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Price pursuant to Section 15.6(a), (b), (c) or (d) occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Price is so required to be adjusted as a result of such other event, and (3) if the “ex” date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined in good faith by the Company’s Board of Directors in a manner consistent with any determination of such value for purposes of Section 15.6(d), whose determination shall be conclusive and described in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date.  For purposes of this paragraph, the term “ex” date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution and (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective.  Notwithstanding the foregoing, whenever successive adjustments to the Conversion Price are called for pursuant to this Section 15.6, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 15.6 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

(3)“fair market value” shall mean the amount which a willing buyer would pay a willing seller in an arm’s length transaction.

(4)“Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(5)“Trading Day” shall mean (x) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national security exchange, a day on which the New York Stock Exchange or such other

80

national security exchange, as applicable, is open for business or (y) if the applicable security is quoted on the Nasdaq National Market, a day on which trades may be made thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, a Business Day.

(f)The Company may make such reductions in the Conversion Price, in addition to those required by Sections 15.6(a), (b), (c) or (d), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

(g)To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least twenty (20) days, the reduction is irrevocable during the period and the Board of Directors shall have made a determination that such reduction would be in the best interests of the Company, which determination shall be conclusive and described in a Board Resolution.  Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall send to the holder of each Note at his last address appearing on the Note Register provided for in Section 2.5 a notice of the reduction at least five (5) days prior to the date the reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect.

(h)No adjustment in the Conversion Price shall be required under this Section 15.6 unless such adjustment would require an increase or decrease of at least one percent (1%) in such price; provided, however, that any adjustments which by reason of this Section 15.6 (h) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.  All calculations under this Article XV shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be.  No adjustment need be made for a change in the par value or no par value of the Common Stock.

(i)Subject to Section 15.6(f), whenever the Conversion Price is adjusted as provided in this Section 15.6, the Company shall promptly file with the Trustee and any conversion agent other than the Trustee an Officer’s Certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.  Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the date on which each adjustment becomes effective and shall send such notice of such adjustment of the Conversion Price to the holder of each Note at his last address appearing on the Note Register provided for in Section 2.5, within twenty (20) days of the effective date of such adjustment.  Failure to deliver such notice shall not effect the legality or validity of any such adjustment.

(j)In any case in which this Section 15.6 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the holder of any Note converted after

81

such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.4.

(k)For purposes of this Section 15.6, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.  The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

Section 15.7Effect of Reclassification, Consolidation, Merger or Sale

Subject to the provisions of Article XVI, if any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation, merger or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock (other than as a result of a change in name, a change in par value or a change in the jurisdiction of incorporation), (iii) any statutory exchange as a result of which holders of Common Stock generally shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock (such transaction, a “Statutory Exchange”), or (iv) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such Note shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, Statutory Exchange, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available to convert all such Notes) immediately prior to such reclassification, change, consolidation, merger, combination, Statutory Exchange, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, that holders of Common Stock who were entitled to vote or consent to such transaction had as to the kind or amount of securities, cash or other property receivable upon such consolidation, merger, combination, Statutory Exchange, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such consolidation, merger, combination, Statutory Exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“non-electing share”), then for the purposes of this Section 15.7 the kind and amount of securities, cash or other property receivable upon such

82

consolidation, merger, combination, Statutory Exchange, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares).  Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XV.  If, in the case of any such reclassification, change, consolidation, merger, combination, Statutory Exchange, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock include shares of stock or other securities and assets of a Person other than the successor or purchasing Person, as the case may be, in such reclassification, change, consolidation, merger, combination, Statutory Exchange, sale or conveyance, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the holders of the Notes as the Company’s Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article XVI herein.

The Company shall cause notice of the execution of such supplemental indenture to be sent to each holder of Notes, at his address appearing on the Note Register provided for in Section 2.5 of this Indenture, within twenty (20) days after execution thereof.  Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions of this Section 15.7 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances.

If this Section 15.7 applies to any event or occurrence, Section 15.6 shall not apply.

Section 15.8Taxes on Shares Issued

The issue of stock certificates on conversions of Notes shall be made without charge to the converting Noteholder for any tax in respect of the issue thereof.  The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 15.9Reservation of Shares; Shares to be Fully Paid; Listing of Common Stock

The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, reserved for the purpose of issuance, no less than one hundred five percent (105%) of the number of shares of Common Stock needed to provide for the issuance of Common Stock upon conversion of all of the Notes without regard to any limitations on conversions or exercise.

The Company will not, by amendment of its articles of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the

83

terms to be observed or performed by it hereunder.  Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any shares of Common Stock issuable upon conversion of the Notes above the Conversion Price then in effect, (ii) will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon conversion of the Notes and (iii) will not take any action which results in any adjustment of the Conversion Price if the total number of shares of Common Stock issuable after the conversion of all of the Notes would exceed the total number of shares of Common Stock then authorized by the Company’s articles of incorporation and available for the purpose of issue upon such exercise.

The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

The Company is obligated to register the Notes and the shares of Common Stock issuable upon conversion of the Notes for resale under the Securities Act pursuant to the Registration Rights Agreement.  The Notes and the shares of Common Stock issuable upon conversion of the Notes shall constitute Registrable Securities (as such term is defined in the Registration Rights Agreement).  Each holder of Notes shall be entitled to all of the benefits afforded to a holder of Registrable Securities under the Registration Rights Agreement and such holder, by its acceptance of a Note, agrees and shall agree to be bound by and to comply with the terms and conditions of the Registration Rights Agreement applicable to such holder as a holder of such Registrable Securities.

The Company shall use commercially reasonable efforts to promptly secure the listing of the shares of Common Stock issuable upon conversion of a Note upon each national securities exchange and automated quotation system, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance upon conversion of such Note) and shall use commercially reasonable efforts to maintain, so long as any other shares of Common Stock shall be so listed, such listing of all shares of Common Stock from time to time issuable upon the conversion of all then outstanding Notes; and the Company shall use commercially reasonable efforts to list on each national securities exchange or automated quotation system, as the case may be, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon conversion of the Notes if and so long as any shares of the same class shall be listed on such national securities exchange or automated quotation system.  The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 15.9.

Section 15.10Responsibility of Trustee

The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any holder of Notes to determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same.  The Trustee and any other conversion agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any

84

time be issued or delivered upon the conversion of any Note; and the Trustee and any other conversion agent make no representations with respect thereto.  Subject to the provisions of Section 8.1, neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article.  Without limiting the generality of the foregoing, neither the Trustee nor any conversion agent shall be under any responsibility to determine whether a supplemental indenture need be entered into under Section 15.7 or the correctness of any provisions contained in any supplemental indenture entered into pursuant to such section relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.7 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.1, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 15.11Notice to Holders Prior to Certain Actions

In case:

(a)the Company shall declare a dividend (or any other distribution) on its Common Stock; or

(b)the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or

(c)of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any shareholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or

(d)of the voluntary or involuntary dissolution, liquidation or winding-up of the Company;

the Company shall cause to be filed with the Trustee and to be sent to each holder of Notes at his address appearing on the Note Register, provided for in Section 2.5 of this Indenture, as promptly as possible but in any event at least fifteen (15) days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur,

85

and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.  Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.

Section 15.12Holder Not Deemed a Shareholder

Except as otherwise specifically provided herein, prior to a Noteholder’s receipt of Common Stock upon conversion of a Note, the Noteholder shall not be entitled, as such, to any rights of a shareholder of the Company, including, without limitation, the right to vote or to consent to any action of the shareholders of the Company, to receive dividends or other distributions, to exercise any preemptive right or to receive dividends or other distributions, or to receive any notice of meetings of shareholders of the Company, and shall not be entitled to receive any notice of any proceedings of the Company.  In addition, nothing contained in this Indenture shall be construed as imposing any liabilities on such holder to purchase any securities (upon conversion of a Note or otherwise) or as a shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

Section 15.13Adjustment to Conversion Price Following Certain Changes of Control

In case (a) a Change of Control occurs as defined in clause (iii) of the definition thereof (disregarding, for purposes of this Section 15.13, the proviso at the end of such definition), (b) 10% or more of the consideration received by holders of the Common Stock in connection with such Change of Control consists of cash or securities or other property that is not traded or scheduled to be traded immediately following such transaction on a U.S. national securities exchange or the Nasdaq National Market and (c) a holder elects to convert its Notes, pursuant to this Article XV, on or prior to February 15, 2008, the Conversion Price for any such Notes surrendered for conversion shall be increased by a number of additional shares of Common Stock (the “Additional Shares”) as described below.

The number of Additional Shares will be determined by reference to the table attached as Schedule A hereto, based on the effective date of such Change in Control (the “Effective Date”) and the price (the “Stock Price”) paid per share of the Common Stock in such corporate transaction. If holders of Common Stock receive only cash in such corporate transaction, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Closing Prices of Common Stock on the five Trading Days up to but not including the Effective Date of the Change in Control.

The Stock Prices set forth in the first row of the table in Schedule A hereto will be adjusted as of any date on which the Conversion Price of the Securities is adjusted pursuant to Section 15.6. The adjusted Stock Price will equal the Stock Price applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Price as so adjusted and the denominator of which is the Conversion Price immediately prior to such adjustment giving rise to the Stock Price adjustment. If an adjustment is made to the Conversion

86

Price pursuant to Section 15.6, the number of Additional Shares will be adjusted by multiplying such amount by a fraction, the numerator of which is the Conversion Price immediately prior to such adjustment and the denominator of which is the Conversion Price as so adjusted.

The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A, in which case:

(i)if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year,

(ii)if the Stock Price is equal to or in excess of $100.00 per share, subject to adjustments set forth in Section 15.6, no Additional Shares will be issued upon conversion, and

(iii)if the Stock Price is less than $18.50 per share, subject to adjustments set forth in Section 15.6, no Additional Shares will be issued upon conversion.

Section 15.14Payment of Additional Conversion Payment and Company Conversion Provisional Payment.

The Company may pay any Company Conversion Provisional Payment required to be paid pursuant to this Indenture in whole or in part in cash and/or through the issuance of Common Stock; provided (i) that Common Stock used to pay any such payment shall be valued at ninety-five percent (95%) of the average Closing Price of the Common Stock for each of the five Trading Days immediately preceding the second Trading Day prior to the Conversion Date, (ii) that a registration statement covering the resale of such Common Stock is effective and available for resale of such Common Stock from the twenty-fifth (25th) Trading Date prior to the Conversion Date to and including the Conversion Date to the extent required under the Registration Rights Agreement and (iii) such Common Stock is listed for trading on the Principal Market (as defined in the Securities Purchase Agreement).

ARTICLE XVI

REPURCHASE RIGHT

Section 16.1Repurchase Right

If, at any time prior to February 15, 2025 there shall occur a Repurchase Event (as defined in Section 16.3), then each holder shall have the right, at such holder’s option, to require the Company to repurchase all of such holder’s Notes, or any portion thereof (in principal amounts of One Thousand United States Dollars ($1,000) or integral multiples thereof), on the date (a “Repurchase Date”) that is forty (40) calendar days after the date of the Company Notice (as defined in Section 16.2(a) below) of such Repurchase Event (or, if such 40th day is not a Business Day, the next succeeding Business Day).  Such repurchase shall be made in cash at a

87

price equal to 100% of the principal amount of Notes such holder elects to require the Company to repurchase together, in each case, with accrued interest, if any, to the applicable Repurchase Date (the “Repurchase Price”).

In addition, Notes shall be purchased by the Company at the option of the holder on February 15, 2010, February 15, 2015 and February 15, 2020 (each, also a “Repurchase Date”), at the Repurchase Price.

Notwithstanding anything in this Article XVI to the contrary, if a redemption date pursuant to Article III shall occur prior to any Repurchase Date established pursuant to a Company Notice under Section 16.2, provided that the Company shall have deposited or set aside an amount of money sufficient to redeem such Notes as set forth in Section 3.2 on or before such Repurchase Date, all such Notes shall be redeemed pursuant to Article III and the repurchase rights hereunder shall have no effect.

Section 16.2Notices; Method of Exercising Repurchase Right, Etc.

(a)Unless the Company shall have theretofore called for redemption all of the outstanding Notes and deposited or set aside an amount of money sufficient to redeem such Notes on the redemption date as set forth in Section 3.2, on or before (x) the tenth (10th) calendar day following the occurrence of a Repurchase Event and (y) January 1, 2010, January 1, 2015 and January 1, 2020, the Company or, at the written request of the Company, the Trustee, shall send to all holders of record of the Notes a notice (the “Company Notice”) in the form as prepared by the Company of the repurchase right set forth herein arising as of the result of the occurrence of a Repurchase Event or on February 15, 2010, February 15, 2015 or February 15, 2020, as applicable.  The Company shall also deliver a copy of such notice to the Trustee.  The Company Notice shall contain the following information:

(1)a brief description of the Repurchase Event, if applicable;

(2)the Repurchase Date;

(3)the CUSIP number(s) of the Note(s) subject to the repurchase right;

(4)the date by which the repurchase right must be exercised;

(5)the last date by which the election to require repurchase, if submitted, must be revoked;

(6)the Repurchase Price;

(7)a description of the procedure which a holder must follow to exercise a repurchase right

(8)the Additional Shares, if any, to be issued pursuant to Section 15.13; and

88

(9)the Conversion Price then in effect, the date on which the right to convert the principal amount of the Notes to be repurchased will terminate and the place or places where Notes may be surrendered for conversion.

No failure of the Company to give the foregoing notices or defect therein shall limit any holder’s right to exercise a repurchase right or affect the validity of the proceedings for the repurchase of Notes.

If any of the foregoing provisions are inconsistent with applicable law, such law shall govern.

(b)To exercise a repurchase right, a holder shall deliver to the Trustee on or before the close of business on the thirty-fifth (35th) day after the Company Notice was sent (i) written notice to the Company (or agent designated by the Company for such purpose) of the holder’s exercise of such right in substantially the form attached hereto as Exhibit C (the “Repurchase Notice”), which Repurchase Notice shall set forth the name of the holder, the principal amount of the Notes to be repurchased, a statement that an election to exercise the repurchase right is being made thereby, and (ii) the Notes with respect to which the repurchase right is being exercised, duly endorsed for transfer to the Company.  Election of repurchase by a holder shall be revocable at any time prior to, but excluding, the Repurchase Date, by delivering written notice to that effect to the Trustee prior to the close of business on the Business Day prior to the Repurchase Date.

(c)If the Company fails to repurchase on the Repurchase Date any Notes (or portions thereof) as to which the repurchase right has been properly exercised, then the principal of such Notes shall, until paid, bear interest to the extent permitted by applicable law from the Repurchase Date at the rate borne by the Note and each such Note shall be convertible into Common Stock in accordance with this Indenture (without giving effect to Section 16.2(b)) until the principal of such Note shall have been paid or duly provided for.

(d)Any Note that is to be repurchased only in part shall be surrendered to the Trustee duly endorsed for transfer to the Company and accompanied by appropriate evidence of genuineness and authority satisfactory to the Company and the Trustee duly executed by, the holder thereof (or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the holder of such Note without service charge, a new Note or Notes, containing identical terms and conditions, of any authorized denomination as requested by such holder in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered.

(e)On or prior to 1:00 p.m., New York City time on the Repurchase Date, the Company shall deposit with the Trustee or with a paying agent (or, if the Company is acting as its own paying agent, segregate and hold in trust as provided in Section 5.4) the Repurchase Price in cash for payment to the holder on the Repurchase Date.

89

(f)If the Company is unable to repurchase on the Repurchase Date all of the Notes (or portions thereof) as to which the repurchase right has been properly exercised, the aggregate amount of Notes the Company may repurchase shall be allocated pro rata among each Note (or portion thereof) surrendered for repurchase, based on the principal amount of such Note, in proportion to the aggregate amount of Notes surrendered for repurchase.

(g)All Notes delivered for repurchase shall be delivered to the Trustee to be canceled in accordance with the provisions of Section 2.8.

QUIXOTE CORPORATION

7% Convertible Senior Subordinated Note due 2025

This Note is one of a duly authorized issue of Notes of the Company, designated as its 7% Convertible Senior Subordinated Notes due 2025 (herein called the “Notes”), initially limited to the aggregate principal amount of Forty Million United States Dollars ($40,000,000), all issued or to be issued under and pursuant to an Indenture dated as of February 9, 2005 (herein called the “Indenture”), between the Company and LaSalle Bank National Association (herein called the “Trustee”), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes.  Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. All capitalized terms used herein without definition shall have the meaning set forth in the Indenture.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, premium, if any, and accrued interest on all Notes may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.  Liquidated damages paid pursuant to Section 15.2 of the Indenture, if any, shall be paid within ten (10) Business Days of the date from which such liquidated damages accrued pursuant to Section 15.2.  Liquidated Damages on the Notes paid pursuant to Section 2(f) of the Registration Rights Agreement, if any, shall be paid at the times and in the manner provided therein.

The Indenture contains provisions permitting the Company and the Trustee in certain limited circumstances, without the consent of the holders of the Notes, and in other circumstances, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute amendments to the Indenture or supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided, however, that no such amendment or supplemental indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof or premium, if any, thereon, or reduce any amount payable on redemption or repurchase thereof, impair, or change in any respect adverse to the holder of Notes, the obligation of the Company to repurchase any Note at the option of the holder in accordance with Article XVI of the Indenture, or impair or adversely affect the right of any Noteholder to institute suit for the payment thereof, or change the currency in which the Notes are payable, or impair or change in any respect adverse to the Noteholders the right to convert the Notes into Common Stock subject to the terms set forth herein, including Section 15.7, without the consent of the holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes,

A-6

the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of all Notes then outstanding.

It is also provided in the Indenture that the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past default or Event of Default under the Indenture and its consequences except (i) a default in the payment of interest or premium, if any, on, or the principal of, the Notes when due, (ii) a failure by the Company to convert any Notes into Common Stock or (iii) a default in respect of a covenant or provisions of the Indenture which under Article XI thereof cannot be modified or amended without the consent of the holders of all Notes then outstanding.  Any such consent or waiver by a holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether any notation thereof is made upon this Note or such other Notes.

The payment of principal of, premium, if any, and interest on the Notes will be subordinated in right of payment to the prior payment in full of Senior Indebtedness as set forth in Article IV of the Indenture.

Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Notes are issuable in registered form without coupons in denominations of One Thousand United States Dollars ($1,000) principal amount and integral multiples thereof.  At the office of Trustee or the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations.

From and after February 20, 2008, except as provided in Section 3.1 of the Indenture, the Company may, at its option, redeem all or any part of the Notes, upon notice as set forth in the Indenture, and the Company shall pay each holder of Notes redeemed a redemption price equal to the principal amount of such Notes, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.

If such notice of redemption has been given as provided in the Indenture, the Notes or portion of Notes called for redemption shall, unless converted into Common Stock pursuant to the terms of the Indenture, become due and payable on the date and at the place or places stated in such notice at the applicable redemption price and interest accrued to, but excluding, the date fixed for redemption, and on and after such date (unless the Company shall default in the payment of such Notes at the redemption price and interest accrued to, but excluding, said date) interest on the Notes or portion of Notes so called for redemption shall cease to accrue and such Notes shall cease after the close of business on the Business Day next preceding the date fixed for redemption to be convertible into Common Stock and, except as provided in Sections 8.5 and 13.4 of the Indenture, to be entitled to any benefit or security under the Indenture, and the holders of such Notes shall have no

right in respect of such Notes except the right to receive the redemption price and unpaid interest to, but excluding, the date fixed for redemption.  On presentation and surrender of such Notes at a place of payment specified in such notice, such Notes or the specified portions thereof to be redeemed shall be paid and redeemed by the Company at the applicable redemption price and interest accrued thereon to, but excluding, the date fixed for redemption; provided that, if the applicable redemption date is an Interest Payment Date, then the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3 of the Indenture.

The Notes are not subject to redemption through the operation of any sinking fund.

Upon the occurrence of a “Repurchase Event,” the Noteholder has the right, at such holder’s option, to require the Company to repurchase all or any portion of such holder’s Notes or any portion thereof (in the principal amounts of One Thousand United States Dollars ($1,000) or integral multiples thereof) on the 40th calendar day (or, if such 40th day is not a Business Day, the next succeeding Business Day) after notice of such Repurchase Event at a price equal to 100% of the principal amount of the Notes such holder elects to require the Company plus accrued interest to the date fixed for repurchase (the ‘Repurchase Price”); provided that if such Repurchase Date is an Interest Payment Date, then the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3 of the Indenture.  Notes shall be purchased by the Company at the option of the holder on February 15, 2010, February 15, 2015 and February 15, 2020 (each, also a “Repurchase Date”), at the Repurchase Price. If a redemption date pursuant to Article III of the Indenture shall occur prior to any Repurchase Date established pursuant to a Company Notice under Section 16.2 of the Indenture, provided that the Company shall have deposited or set aside an amount of money sufficient to redeem such Notes as set forth in Section 3.2 of the Indenture on or before such Repurchase Date, all such Notes shall be redeemed pursuant to Article III of the Indenture and the repurchase rights under Article XVI of the Indenture shall have no effect.

Subject to the provisions of the Indenture, the holder hereof has the right, at its option, at any time following the date of original issuance of the Notes and prior to the close of business on February 15, 2025 (except that, with respect to any Note or portion of a Note that shall be called for redemption, such right shall terminate, except as otherwise provided in the Indenture, at the close of business on the Business Day next preceding the date fixed for redemption unless the Company shall default in payment due upon redemption), to convert the principal hereof or any portion of such principal which is One Thousand United States Dollars ($1,000) or an integral multiple thereof, into that number of fully paid and non-assessable shares of the Company’s Common Stock, as said shares shall be constituted at the date of conversion, obtained by dividing the principal amount of this Note or portion thereof to be converted by the conversion price of $25.90 or such conversion price as adjusted from time to time as provided in the Indenture, upon surrender of this Note, together with a conversion notice as provided in the Indenture and this Note, to the Company at the office or agency of the Company maintained for that purpose, which shall be the Corporate Trust Office of the Trustee, or at any other office or agency permitted by the Indenture, and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney.  The Company shall pay in cash, on this Note or portion thereof

A-8

surrendered for conversion during the period from the close of business on any Interest Payment Date to which interest has been fully paid through the close of business on the Business Day preceding the record date for the next such Interest Payment Date, accrued and unpaid interest, if any, to, but excluding, the date of conversion.  Any such payment of interest shall be made with ten (10) Business Days after the Conversion Date.  Notwithstanding the foregoing, if this Note shall be surrendered for conversion during the period from the close of business on any record date for any Interest Payment Date through the close of business on the Business Day next preceding such Interest Payment Date, the holder (unless the Note or the portion thereof being converted shall have been called for redemption pursuant to a redemption notice sent to the Noteholders in accordance with Section 3.2 of the Indenture or shall have become due prior to such Interest Payment Date as a result of exercise of the repurchase right set forth in Article XVI of the Indenture) must, at the time of conversion of the Note, pay by wire transfer of immediately available funds or other funds acceptable to the Company, an amount equal to the interest otherwise payable on such Interest Payment Date on the principal amount being converted; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Notes.  No fractional shares of Common Stock will be issued upon any conversion, but an adjustment in cash will be paid to the holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion.

The Company may, at its option, subject to stisfaction of certain conditions set forth in Section 15.3 of the Indenture, automatically convert all or a portion of the Notes (an “Automatic Conversion”) at any time prior to February 15, 2025 if the Closing Price (as defined in the Indenture) per share of the Common Stock has exceeded one hundred and fifty percent (150%) of the Conversion Price then in effect for at least twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days ending within the thirty (30) Trading Days  prior to the date the Company gives to all holders of Notes a notice specifying the date on which an Automatic Conversion will become effective.  If the effective date of an Automatic Conversion is prior to February 15, 2008, the Company shall make an additional payment in cash or, under certain circumstances, in shares of Common Stock, to each holder of Notes with respect to the Notes converted, in an amount equal to $210 per each One Thousand United States Dollars ($1,000) principal amount of the Note (the “Company Conversion Provisional Payment”), less the amount of any interest actually paid on the portion of the principal amount of the Note to be converted prior to the effective date of the Automatic Conversion (and, if the Note is converted between a record date and the next Interest Payment Date, less interest payable on each One Thousand United States Dollars ($1,000) principal amount of the Note on such next Interest Payment Date). Common Stock used to pay any Company Conversion Provisional Payment shall be valued at ninety-five percent (95%) of the average Closing Price of the Common Stock for each of the five Trading Days immediately preceding the second Trading Day prior to the Conversion Date.

Unless the Company shall have theretofore called for redemption all of the Notes then outstanding, if the Company elects to convert all or a portion of the Notes pursuant to its Automatic Conversion right, the Company, or at its request (which must be received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below unless a shorter period is agreed to by the Trustee), the Trustee in the name of and at the expense of the Company, shall send or cause to be sent a notice of the Automatic Conversion not more than thirty

A-9

(30) days but not less than five (5) days before the date of effectiveness of the Automatic Conversion as set forth in the Indenture.  In case the Notes are to be converted in part only, the notice shall state the portion of the principal amount thereof to be converted and shall state that on and after the effective date of the Automatic Conversion, upon surrender of such Note, a new Note or Notes in principal amount equal to the unconverted portion thereof will be issued.

In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes not converted prior to the expiration of such conversion right by an agreement with one or more investment bankers or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable redemption price and interest accrued to the date fixed for redemption, of such Notes.

QUIXOTE CORPORATION

7% Convertible Senior Subordinated Note due 2025

This Note is one of a duly authorized issue of Notes of the Company, designated as its 7% Convertible Senior Subordinated Notes due 2025 (herein called the “Notes”), initially limited to the aggregate principal amount of Forty Million United States Dollars ($40,000,000), all issued or to be issued under and pursuant to an Indenture dated as of February 9, 2005 (herein called the “Indenture”), between the Company and LaSalle Bank National Association (herein called the “Trustee”), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes.  Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. All capitalized terms used herein without definition shall have the meaning set forth in the Indenture.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of, premium, if any, and accrued interest on all Notes may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.  Liquidated damages paid pursuant to Section 15.2 of the Indenture, if any, shall be paid within ten (10) Business Days of the date from which such liquidated damages accrued pursuant to Section 15.2.  Liquidated Damages on the Notes paid pursuant to Section 2(f) of the Registration Rights Agreement, if any, shall be paid at the times and in the manner provided therein.

The Indenture contains provisions permitting the Company and the Trustee in certain limited circumstances, without the consent of the holders of the Notes, and in other circumstances, with the consent of the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute amendments to the Indenture or supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided, however, that no such amendment or supplemental indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or extend the time of payment of interest thereon, or reduce the principal amount thereof or premium, if any, thereon, or reduce any amount payable on redemption or repurchase thereof, impair, or change in any respect adverse to the holder of Notes, the obligation of the Company to repurchase any Note at the option of the holder in accordance with Article XVI of the Indenture, or impair or adversely affect the right of any Noteholder to institute suit for the payment thereof, or change the currency in which the Notes are payable, or impair or change in any respect adverse to the Noteholders the right to convert the Notes into Common Stock subject to the terms set forth herein, including Section 15.7, without the consent of the holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the holders of

which are required to consent to any such supplemental indenture, without the consent of the holders of all Notes then outstanding.

It is also provided in the Indenture that the holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past default or Event of Default under the Indenture and its consequences except (i) a default in the payment of interest or premium, if any, on, or the principal of, the Notes when due, (ii) a failure by the Company to convert any Notes into Common Stock or (iii) a default in respect of a covenant or provisions of the Indenture which under Article XI thereof cannot be modified or amended without the consent of the holders of all Notes then outstanding.  Any such consent or waiver by a holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether any notation thereof is made upon this Note or such other Notes.

The payment of principal of, premium, if any, and interest on the Notes will be subordinated in right of payment to the prior payment in full of Senior Indebtedness as set forth in Article IV of the Indenture.

Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Notes are issuable in registered form without coupons in denominations of One Thousand United States Dollars ($1,000) principal amount and integral multiples thereof.  At the office of Trustee or the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations.

From and after February 20, 2008, except as provided in Section 3.1 of the Indenture, the Company may, at its option, redeem all or any part of the Notes, upon notice as set forth in the Indenture, and the Company shall pay each holder of Notes redeemed a redemption price equal to the principal amount of such Notes, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption.

If such notice of redemption has been given as provided in the Indenture, the Notes or portion of Notes called for redemption shall, unless converted into Common Stock pursuant to the terms of the Indenture, become due and payable on the date and at the place or places stated in such notice at the applicable redemption price and interest accrued to, but excluding, the date fixed for redemption, and on and after such date (unless the Company shall default in the payment of such Notes at the redemption price and interest accrued to, but excluding, said date) interest on the Notes or portion of Notes so called for redemption shall cease to accrue and such Notes shall cease after the close of business on the Business Day next preceding the date fixed for redemption to be convertible into Common Stock and, except as provided in Sections 8.5 and 13.4 of the Indenture, to be entitled to any benefit or security under the Indenture, and the holders of such Notes shall have no right in respect of such Notes except the right to receive the

redemption price and unpaid interest to, but excluding, the date fixed for redemption.  On presentation and surrender of such Notes at a place of payment specified in such notice, such Notes or the specified portions thereof to be redeemed shall be paid and redeemed by the Company at the applicable redemption price and interest accrued thereon to, but excluding, the date fixed for redemption; provided that, if the applicable redemption date is an Interest Payment Date, then the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3 of the Indenture.

The Notes are not subject to redemption through the operation of any sinking fund.

Upon the occurrence of a “Repurchase Event,” the Noteholder has the right, at such holder’s option, to require the Company to repurchase all or any portion of such holder’s Notes or any portion thereof (in the principal amounts of One Thousand United States Dollars ($1,000) or integral multiples thereof) on the 40th calendar day (or, if such 40th day is not a Business Day, the next succeeding Business Day) after notice of such Repurchase Event at a price equal to 100% of the principal amount of the Notes such holder elects to require the Company plus accrued interest to the date fixed for repurchase (the ‘Repurchase Price”); provided that if such Repurchase Date is an Interest Payment Date, then the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the relevant record date subject to the terms and provisions of Section 2.3 of the Indenture.  Notes shall be purchased by the Company at the option of the holder on February 15, 2010, February 15, 2015 and February 15, 2020 (each, also a “Repurchase Date”), at the Repurchase Price. If a redemption date pursuant to Article III of the Indenture shall occur prior to any Repurchase Date established pursuant to a Company Notice under Section 16.2 of the Indenture, provided that the Company shall have deposited or set aside an amount of money sufficient to redeem such Notes as set forth in Section 3.2 of the Indenture on or before such Repurchase Date, all such Notes shall be redeemed pursuant to Article III of the Indenture and the repurchase rights under Article XVI of the Indenture shall have no effect.

Subject to the provisions of the Indenture, the holder hereof has the right, at its option, at any time following the date of original issuance of the Notes and prior to the close of business on February 15, 2025 (except that, with respect to any Note or portion of a Note that shall be called for redemption, such right shall terminate, except as otherwise provided in the Indenture, at the close of business on the Business Day next preceding the date fixed for redemption unless the Company shall default in payment due upon redemption), to convert the principal hereof or any portion of such principal which is One Thousand United States Dollars ($1,000) or an integral multiple thereof, into that number of fully paid and non-assessable shares of the Company’s Common Stock, as said shares shall be constituted at the date of conversion, obtained by dividing the principal amount of this Note or portion thereof to be converted by the conversion price of $25.90 or such conversion price as adjusted from time to time as provided in the Indenture, upon surrender of this Note, together with a conversion notice as provided in the Indenture and this Note, to the Company at the office or agency of the Company maintained for that purpose, which shall be the Corporate Trust Office of the Trustee, or at any other office or agency permitted by the Indenture, and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized

attorney.  The Company shall pay in cash, on this Note or portion thereof surrendered for conversion during the period from the close of business on any Interest Payment Date to which interest has been fully paid through the close of business on the Business Day preceding the record date for the next such Interest Payment Date, accrued and unpaid interest, if any, to, but excluding, the date of conversion.  Any such payment of interest shall be made with ten (10) Business Days after the Conversion Date.  Notwithstanding the foregoing, if this Note shall be surrendered for conversion during the period from the close of business on any record date for any Interest Payment Date through the close of business on the Business Day next preceding such Interest Payment Date, the holder (unless the Note or the portion thereof being converted shall have been called for redemption pursuant to a redemption notice sent to the Noteholders in accordance with Section 3.2 of the Indenture or shall have become due prior to such Interest Payment Date as a result of exercise of the repurchase right set forth in Article XVI of the Indenture) must, at the time of conversion of the Note, pay by wire transfer of immediately available funds or other funds acceptable to the Company, an amount equal to the interest otherwise payable on such Interest Payment Date on the principal amount being converted; provided, however, that no such payment need be made if there shall exist at the time of conversion a default in the payment of interest on the Notes.  No fractional shares of Common Stock will be issued upon any conversion, but an adjustment in cash will be paid to the holder, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion.

The Company may, at its option, subject to satisfaction of certain conditions set forth in Section 15.3 of the Indenture, automatically convert all or a portion of the Notes (an “Automatic Conversion”) at any time prior to February 15, 2025 if the Closing Price (as defined in the Indenture) per share of the Common Stock has exceeded one hundred and fifty percent (150%) of the Conversion Price then in effect for at least twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days ending within the thirty (30) Trading Days prior to the date the Company gives to all holders of Notes a notice specifying the date on which an Automatic Conversion will become effective.  If the effective date of an Automatic Conversion is prior to February 15, 2008, the Company shall make an additional payment in cash or, under certain circumstances, in shares of Common Stock, to each holder of Notes with respect to the Notes converted, in an amount equal to $210 per each One Thousand United States Dollars ($1,000) principal amount of the Note (the “Company Conversion Provisional Payment”), less the amount of any interest actually paid on the portion of the principal amount of the Note to be converted prior to the effective date of the Automatic Conversion (and, if the Note is converted between a record date and the next Interest Payment Date, less interest payable on each One Thousand United States Dollars ($1,000) principal amount of the Note on such next Interest Payment Date). Common Stock used to pay any Company Conversion Provisional Payment shall be valued at ninety-five percent (95%) of the average Closing Price of the Common Stock for each of the five Trading Days immediately preceding the second Trading Day prior to the Conversion Date.

Unless the Company shall have theretofore called for redemption all of the Notes then outstanding, if the Company elects to convert all or a portion of the Notes pursuant to its Automatic Conversion right, the Company, or at its request (which must be received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below unless a shorter period is agreed to by the Trustee), the Trustee in the name of

and at the expense of the Company, shall send or cause to be sent a notice of the Automatic Conversion not more than thirty (30) days but not less than five (5) days before the date of effectiveness of the Automatic Conversion as set forth in the Indenture.  In case the Notes are to be converted in part only, the notice shall state the portion of the principal amount thereof to be converted and shall state that on and after the effective date of the Automatic Conversion, upon surrender of such Note, a new Note or Notes in principal amount equal to the unconverted portion thereof will be issued.

In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes not converted prior to the expiration of such conversion right by an agreement with one or more investment bankers or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable redemption price and interest accrued to the date fixed for redemption, of such Notes.

(a)Mandatory Registration.  The Company shall use its best efforts to prepare and, as soon as practicable but in no event later than 30 calendar days after the Closing Date (as that term is defined in the Securities Purchase Agreement) (the “Filing Deadline”), file with the Commission a Registration Statement on Form S-3 covering the resale of all of the Registrable Securities.  In the event that Form S-3 is unavailable for such a registration, the Company shall use such other form as is available for such a registration, subject to the provisions of Section 2(d) of this Agreement.  The Registration Statement prepared pursuant hereto shall register the Registrable Securities for resale, including at least 105%of the number of shares of Common Stock issuable upon conversion of the Notes by the Investors from time to time in accordance with the methods of distribution elected by such Investors or such other amount as required by Section 4(e) of the Securities Purchase Agreement.  The Company shall use its reasonable best efforts to have the Registration Statement declared effective by the Commission as soon as practicable, but not later than 90 calendar days after the Closing Date (the “Effectiveness Deadline”); provided, however, that if the Commission reviews the Registration Statement and requires the Company to make modifications thereto, then the Effectiveness Deadline shall be extended to 120 calendar days after the Closing Date.  In the event that, after the Closing Date and before the Registration Statement is declared effective, the offices of the Commission are

2

closed due to acts of God, war or terror, the Effectiveness Deadline will be extended by a number of days equal to the days of any such closure.

(b)Allocation of Registrable Securities. The initial number of Conversion Shares included in any Registration Statement and each increase in the number of Conversion Shares included therein shall be allocated pro rata among the Investors based on the number of Conversion Shares (determined as if all of the Notes held by Investors then outstanding have been converted into Conversion Shares without regard to any limitations on conversion of the Notes) held by each Investor at the time the Registration Statement covering such initial number of Conversion Shares or increase thereof is declared effective by the Commission.  In the event that an Investor sells or otherwise transfers any of such Investor’s Registrable Securities, each transferee shall be allocated the portion of the then remaining number of Registrable Securities included in such Registration Statement allocable to the transferor.  In no event shall the Company include any securities other than Registrable Securities on any Registration Statement without the prior written consent of the Investors holding at least a majority of the Conversion Shares, determined as if all of the Notes held by Investors then outstanding have been converted into Conversion Shares without regard to any limitations on conversion of the Notes.

(c)Legal Counsel.  Subject to Section 5 of this Agreement, the Investors holding at least a majority of the Conversion Shares, determined as if all of the Notes held by Investors then outstanding have been converted into Conversion Shares without regard to any limitations on conversion of the Notes, shall have the right to select one legal counsel to review and comment upon any registration pursuant to this Agreement (the “Legal Counsel”), which the Investors agree shall be Schulte Roth & Zabel LLP or such other counsel as is thereafter designated in writing by the holders of at least a majority of the Conversion Shares, determined as set forth above.  Schulte Roth & Zabel LLP, or any other counsel designated in writing by the holders of at least a majority of the Conversion Shares, shall not represent any Investor that sends such counsel written notice that such Investor does not wish such counsel to represent it in connection with the matters discussed in this Section 2(c).  The Investors, other than any Investor that delivers the notice discussed in the preceding sentence, hereby waive any conflict of interest or potential conflict of interest that may arise as a result of the representation of such Investors by Schulte Roth & Zabel LLP in connection with the subject matter of this Agreement.  The provision will not prohibit any other counsel to an Investor from reviewing and commenting on any registration filed pursuant to this Agreement at no cost to the Company.

(d)Ineligibility for Form S-3.  If Form S-3 is not available for the registration of the resale of the Registrable Securities hereunder or the Company is not permitted by the Securities Act or the Commission to use Form S-3, then the Company shall (i) register the resale of the Registrable Securities on another appropriate form reasonably acceptable to the holders of at least a majority of the Conversion Shares, determined as if all of the Notes held by Investors then outstanding have been converted into Conversion Shares without regard to any limitations on conversion of the Notes and (ii) undertake to register the Registrable Securities on Form S-3 as soon as such form is available; provided, however, that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering all of the Registrable Securities has been declared effective by the Commission or, if earlier, until the end of the Registration Period (as defined in Section 3(a)).

3

(e)Sufficient Number of Shares Registered.  In the event the number of Conversion Shares registered under a Registration Statement filed pursuant to Section 2(a) of this Agreement is insufficient to cover all of the Conversion Shares or all of an Investor’s allocated portion of the Conversion Shares pursuant to Section 2(b) of this Agreement, the Company shall amend the Registration Statement, or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover at least one hundred five percent(105%) of the number of such Conversion Shares as of the trading day immediately preceding the date of the filing of such amendment and/or new Registration Statement, in each case, as soon as practicable, but in no event later than fifteen (15) days after the necessity therefor arises.  The Company shall use its reasonable best efforts to cause such amendment and/or new Registration Statement to become effective as soon as practicable following the filing thereof.  The calculation of the number of shares sufficient to cover all of the Conversion Shares shall be made without regard to any limitations on the conversion of the Notes, and such calculation shall assume that all of the Notes are then convertible into shares of Common Stock at the then prevailing Conversion Price (as defined in the Notes).  Notwithstanding anything herein to the contrary, if the amendment to the Registration Statement or new Registration Statement required by this Section 2(e) relates to a number of Conversion Shares equal to or greater than ten percent (10%) of the number of Conversion Shares as of the trading day immediately preceding the date of the filing of such amendment and/or new Registration Statement, such amendment or new Registration Statement shall be declared effective by the Commission not later than 90 calendar days after the filing date thereof; provided, however, that if the Commission reviews such amendment or new Registration Statement and requires the Company to make modifications thereto, then this deadline shall be extended to 120 calendar days after the filing date.  In the event that, after the Closing Date and before the Registration Statement is declared effective, the offices of the Commission are closed due to acts of God, war or terror, this deadline will be extended by a number of days equal to the days of any such closure.

(f)Effect of Failure to File and Obtain and Maintain Effectiveness of Registration Statement.  Subject to any elections made pursuant to Section 4(b), if (i) a Registration Statement covering all the Registrable Securities is not filed with the Commission on or before the Filing Deadline or is not declared effective by the Commission on or before the Effectiveness Deadline, (ii) a Registration Statement covering all of the Registrable Securities required to be covered thereby, as described in Section 2(e) of this Agreement, is not filed with the Commission on or before the deadline described in Section 2(e) of this Agreement or is not declared effective by the Commission on or before the deadline described in Section 2(e) of this Agreement, (iii) on any day after such Registration Statement has been declared effective by the Commission, sales of all of the Registrable Securities required to be included on such Registration Statement cannot be made as a matter of law (other than during an Allowable Grace Period (as defined in Section 3(o) of this Agreement)) pursuant to such Registration Statement (including, without limitation, because of a failure to keep such Registration Statement effective, to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or to register a sufficient number of shares of Common Stock), or (iv) a Grace Period (as defined in Section 3(o) of this Agreement) exceeds the length of an Allowable Grace Period (each of the items described in clauses (i), (ii), (iii) and (iv) above shall be referred to as a “Registration Delay”), then the Company shall pay to each holder of the Notes or Conversion Shares an amount in cash equal to the product of (i) the initial principal amount paid for the Note

4

held by such holder or the related Conversion Shares multiplied by (ii) the product of (I) the percentage determined by dividing (A) the Applicable Percentage by (B) 360, multiplied by (II) the sum of (x) the number of days (including any partial days) after the Filing Deadline or the deadline described in Section 2(e) of this Agreement, as applicable, that the Registration Statement is not filed with the Commission, plus (y) the number of days (including any partial days) after the Effectiveness Deadline or the deadline described in Section 2(e) of this Agreement that the Registration Statement is not declared effective by the Commission, plus (z) after the Registration Statement has been declared effective by the Commission, the number of days (including any partial days) that such Registration Statement is not available (other than during an Allowable Grace Period) for the sale of all the Registrable Securities.  The “Applicable Percentage” shall mean (A) for periods that only include days on or before the day that is 60 days after the commencement of a Registration Delay, eight-tenths percent (0.8%), (B) for periods that only include days after the date that is 60 days after the commencement of a Registration Delay, one and two-tenths percent (1.2%) and (C) for periods that include days both before and after the date that is 60 days after the commencement of a Registration Delay, a percentage equal to a fraction, the numerator of which shall be the sum of (i) the number of days in such period that are on or before the date that is 60 days after the commencement of such Registration Delay multiplied by eight-tenths percent (0.8%) and (ii) the number of days in such period that are after the date that is 60 days after the commencement of such Registration Delay multiplied by one and two-tenths percent (1.2%) and the denominator of which shall be the total number of days comprising such period.  The payments to which a holder shall be entitled pursuant to this Section 2(f) are referred to herein as “Registration Delay Payments.”  The Registration Delay Payments shall be paid in cash on the earlier of (A) the last day of the calendar month during which such Registration Delay Payments are incurred and (B) the third Business Day after the event or failure giving rise to the Registration Delay Payments is cured.  In the event the Company fails to make Registration Delay Payments in a timely manner, such Registration Delay Payments shall bear interest at the rate of one and six-tenths percent (1.6%) per month (prorated for partial months) until paid in full.

SECTION 3.Related Obligations.  At such time as the Company is obligated to file a Registration Statement with the Commission pursuant to Section 2(a), 2(d) or 2(e) of this Agreement, the Company will use reasonable best efforts to effect the registration of all of the Registrable Securities in accordance with the intended method of disposition thereof and, in connection with its obligations with respect to the Registration Statement, the Company shall have the following obligations:

(a)The Company shall promptly prepare and file with the Commission a Registration Statement with respect to all of the Registrable Securities (but in no event later than the applicable Filing Deadline) and use reasonable best efforts to cause such Registration Statement relating to all of the Registrable Securities required to be covered thereby to become effective as soon as practicable after such filing (but in no event later than the applicable Effectiveness Deadline).  The Company shall, subject to the terms of this Agreement, keep each Registration Statement effective pursuant to Rule 415 at all times during the period from the date it is initially declared effective until the earliest of (i) the second anniversary of the date such Registration Statement is filed, (ii) the date as of which all of the Investors (other than any Investors who are “affiliates” of the Company as such term is used in Rule 144(k) promulgated under the Securities Act) may sell all of the Registrable Securities without restriction pursuant to

5

Rule 144(k) (or the successor rule thereto) promulgated under the Securities Act, (iii) the date on which all Registrable Securities have been transferred under Rule 144 under circumstances in which any legend borne by such Registrable Securities  relating to restrictions on transferability thereof, under the Securities Act or otherwise, is removed or (iv) the date on which all of the Investors shall have sold all of the Registrable Securities (the “Registration Period”) pursuant to a Registration Statement, which Registration Statement, as of its filing and effective dates and each day thereafter (including all amendments or supplements thereto, as of their respective filing and effective dates and each day thereafter), shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, not misleading, and the prospectus contained in such Registration Statement, as of its filing date and each day thereafter (including all amendments and supplements thereto, as of their respective filing dates and each day thereafter), shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading.

(b)Subject to Section 3(o) of this Agreement, the Company shall prepare and file with the Commission such amendments (including post-effective amendments) and supplements to the Registration Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424 (or any successor rule thereto) promulgated under the Securities Act, as may be necessary to keep such Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act.  In the case of amendments and supplements to a Registration Statement and the prospectus used in connection with such Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b)) by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous report under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, or any similar successor statute (the “Exchange Act”), the Company shall have incorporated such report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the Commission on the same day on which the Exchange Act report is filed which created the requirement for the Company to amend or supplement such Registration Statement and prospectus.

(c)The Company shall permit Legal Counsel, or if no Legal Counsel shall have been chosen by the Investors, the Investors and their respective legal counsel, to review and provide written comment upon each Registration Statement, prospectus and all amendments and supplements thereto at least five (5) Business Days prior to their filing with the Commission.  The Company shall furnish to the Investors and Legal Counsel, without charge, (i) promptly after receipt of such correspondence, copies of all correspondence from the Commission or the staff of the Commission to the Company or its representatives relating to each Registration Statement, prospectus and all amendments and supplements thereto, (ii) promptly after the same is prepared and filed with the Commission, one (1) copy of each Registration Statement, prospectus and all amendments and supplements thereto, including all exhibits and financial statements related thereto, and (iii) promptly upon the effectiveness of each Registration Statement and each amendment and supplement thereto, one (1) copy of the prospectus included in each such Registration Statement and all amendments and supplements thereto.  The Company agrees that it will, and it will cause its counsel to, consider in good faith any comments or objections from

6

Legal Counsel, or if no Legal Counsel shall have been selected, the Investors and their respective legal counsel, as to the form or content of each Registration Statement, prospectus and all amendments or supplements thereto or any written communications with the Commission or the staff of the Commission concerning a Registration Statement, prospectus or any amendment or supplement thereto including, without limitation, a request for acceleration of the effectiveness of each Registration Statement, prospectus and all amendments or supplements thereto. The Company shall submit to the Commission, within two (2) Business Days after the Company learns that no review of a particular Registration Statement will be made by the staff of the SEC or that the staff has no further comments on a particular Registration Statement, as the case may be, a request for acceleration of effectiveness of such Registration Statement to a time and date not later than 48 hours after the submission of such request; provided however, the Company may delay the submission of the request for acceleration (or delay the effectiveness of such Registration Statement) for up to thirty (30) days if the Company has material non-public information concerning the Company if the disclosure of such information at the time is not, in the good faith judgment of the Board of Directors of the Company relying upon the opinion of counsel, in the best interests of the Company; provided, further however, that the Company shall promptly notify the Investors in writing of the existence of material non-public information giving rise to a delay in effectiveness (provided that the Company shall not disclose the content of such material non-public information to the Investors); and provided further that any delay by the Company in accordance with this sentence shall not affect the entitlement of a holder to any  Registration Delay Payment determined in accordance with Section 2(f).

(d)The Company shall furnish to each Investor whose Registrable Securities are included in any Registration Statement, without charge to such Investor, (i) promptly after the same is prepared and filed with the Commission, at least one copy of such Registration Statement and all amendments and supplements thereto, including all exhibits and financial statements and each preliminary prospectus, (ii) upon the effectiveness of each Registration Statement, such number of copies of the prospectus included in such Registration Statement and all amendments and supplements thereto as such Investor may reasonably request, and (iii) such other documents, including copies of any preliminary or final prospectus, as such Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities.

(e)Subject to Section 3(o) of this Agreement, and excluding any Registrable Securities held by Investors electing to exclude their Registrable Securities from the Registration Statement under Section 4(b), the Company shall use reasonable best efforts to (i) promptly register and qualify, unless an exemption from registration and qualification applies, the resale of the Registrable Securities under such other securities or “blue sky” laws of all applicable jurisdictions in the United States as any holder of Registrable Securities reasonably requests in writing, (ii) promptly prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) promptly take such other actions as may be reasonably necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, (iv) promptly cause the Registrable Securities covered by the applicable Registration Statement to be registered with or approved by such other federal, state and local governmental agencies or authorities, and self-regulatory organizations in the United States as may be necessary to enable the Investors to

7

consummate the disposition of such Registrable Securities as contemplated by the Registration Statement; without limitation to the foregoing, the Company shall, if applicable, provide all such information as may be required by the NASD in connection with the offering under the Registration Statement of the Registrable Securities (including, without limitation, such as may be required by NASD Rule 2710 or 2720), and shall cooperate with each Investor in connection with any filings required to be made with the NASD by such Investor in that regard and (v) promptly take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to file a general consent to service of process in any such jurisdiction, except in such jurisdictions where the Company is subject to service of process.  The Company shall promptly notify each Investor who holds Registrable Securities and Legal Counsel of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of notice of the initiation or threatening of any proceeding for such purpose.

(f)Notwithstanding anything to the contrary set forth herein, as promptly as practicable after becoming aware of such event, the Company shall notify each Investor and Legal Counsel in writing of the happening of any event as a result of which (i) the Registration Statement or any amendment or supplement thereto, as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) the prospectus related to such Registration Statement or any amendment or supplement thereto includes an untrue statement of a material fact or omission to state 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, and, subject to Section 3(o) of this Agreement, promptly prepare a supplement or amendment to such Registration Statement and prospectus to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to each Investor and Legal Counsel as such Investor or Legal Counsel may reasonably request.  The Company shall also promptly notify each Investor and Legal Counsel in writing (i) when a prospectus and each prospectus supplement or amendment thereto has been filed, and when a Registration Statement and each amendment (including post-effective amendments) and supplement thereto has been declared effective by the Commission (notification of such effectiveness shall be delivered to each Investor and Legal Counsel by facsimile on the same day of such effectiveness and by overnight mail), (ii) of any request by the Commission for amendments or supplements to a Registration Statement or related prospectus or related information, and (iii) of the Company’s reasonable determination that an amendment (including any post-effective amendment) or supplement to a Registration Statement or prospectus would be appropriate (subject to Section 3(o) hereof).

(g)Subject to Section 3(o) of this Agreement, the Company shall use reasonable best efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction, and (ii) if such an order or suspension is issued, obtain the withdrawal of such order or suspension at the earliest practicable moment and notify each holder of Registrable Securities and Legal Counsel of the issuance of such order and the resolution thereof or its receipt of notice of the initiation or threat of any proceeding for such purpose.

8

(h)The Company shall hold in confidence and not make any disclosure of information concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with United States federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, prospectus or any amendment or supplement thereto, (iii) the release of such information is ordered pursuant to a subpoena or other final, non-appealable order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the public other than by disclosure in violation of this Agreement or any other agreement.  The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, unless ordered or requested by the Commission or other governmental authority not to do so, give prompt written notice to such Investor and allow such Investor, at the Investor’s expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

(i)The Company shall use reasonable best efforts to cause all the Conversion Shares to be listed on each securities exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Conversion Shares is then permitted under the rules of such exchange.  The Company shall pay all fees and expenses in connection with satisfying its obligation under this Section 3(i).

(j)The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended (the “TIA”), in connection with the registration of the Registrable Securities, cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the TIA and execute, and use their best efforts to cause the Trustee to execute, all documents as may be required to effect such changes and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner;

(k)In connection with any sale or transfer of Registrable Securities pursuant to a Registration Statement, the Company shall cooperate with the Investors who hold Registrable Securities being offered and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Registration Statement and enable such certificates to be in such denominations or amounts, as the case may be, as the Investors may reasonably request and, registered in such names as the Investors may request.

(l)If requested by an Investor, the Company shall (i) as soon as practicable, incorporate in each prospectus supplement or post-effective amendment to the Registration Statement such information as an Investor provides in writing and reasonably requests to be included therein relating to the sale and distribution of the Registrable Securities, and (ii) as soon as practicable, make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment.

(m)The Company shall comply with all applicable rules and regulations of the Commission in connection with any registration hereunder.

9

(n)Within two (2) Business Days after a Registration Statement is ordered effective by the Commission, the Company will so notify the transfer agent for the Registrable Securities and the Investors whose Registrable Securities are included in the Registration Statement.

(o)Notwithstanding anything to the contrary herein, at any time after a Registration Statement has been declared effective by the Commission, the Company may delay the disclosure of material non-public information concerning the Company if the disclosure of such information at the time is not, in the good faith judgment of the Board of Directors of the Company relying upon the opinion of counsel, in the best interests of the Company (a “Grace Period”); provided, however, that the Company shall promptly (i) notify the Investors in writing of the existence of material non-public information giving rise to a Grace Period (provided that the Company shall not disclose the content of such material non-public information to the Investors) and the date on which the Grace Period will begin, and (ii) notify the Investors in writing of the date on which the Grace Period ends; provided further, that no single Grace Period shall exceed thirty (30) consecutive days, and during any three hundred sixty-five (365) day period, the aggregate of all of the Grace Periods shall not exceed an aggregate of sixty (60) days and the first day of any Grace Period must be at least ten (10) trading days after the last day of any prior Grace Period (each Grace Period complying with this provision being an “Allowable Grace Period”).  For purposes of determining the length of a Grace Period, the Grace Period shall be deemed to begin on and include the date the Investors receive the notice referred to in clause (i) above and shall end on and include the later of the date the Investors receive the notice referred to in clause (ii) above and the date referred to in such notice; provided, however, that no Grace Period shall be longer than an Allowable Grace Period.  The provisions of Section 3(g) of this Agreement shall not be applicable during the period of any Allowable Grace Period.  Upon expiration of the Grace Period, the Company shall again be bound by the first sentence of Section 3(f) of this Agreement.

(p)The Company shall provide, prior to the effective date of any Registration Statement hereunder, a CUSIP number for the Registrable Securities registered under such Registration Statement.

SECTION 4.Obligations Of The Investors.

(a)At least five (5) Business Days prior to the first anticipated filing date of a Registration Statement, the Company shall notify each Investor in writing of the information the Company requires from each such Investor if such Investor elects to have any of such Investor’s Registrable Securities included in such Registration Statement.  It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a particular Investor that such Investor shall furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the effectiveness of the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request.  Each Investor shall promptly notify the Company of any material change with respect to such information previously provided to the Company by such Investor.

10

(b)Each Investor agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor’s election to exclude all of such Investor’s Registrable Securities from such Registration Statement, in which case, such Investor does not need to so cooperate with the Company until it notifies the Company of its desire to include one or more shares of the Registrable Securities in such Registration Statement.

(c)Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(g) or 3(o) of this Agreement or the first sentence of Section 3(f) of this Agreement, such Investor will immediately discontinue disposition of Registrable Securities pursuant to any Registration Statements covering such Registrable Securities until such Investor’s receipt of the copies of the amended or supplemented prospectus contemplated by Section 3(g) of this Agreement or the first sentence of Section 3(f) of this Agreement or receipt of notice that no amendment or supplement is required and, if so directed by the Company, such Investor shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies of the prospectus covering such Registrable Securities current at the time of receipt of such notice (other than a single file copy, which such Investor may keep) in such Investor’s possession.

SECTION 5.Expenses Of Registration.  All expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3 of this Agreement, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, transfer agent fees and fees and disbursements of counsel for the Company, shall be paid by the Company.  The Company shall pay all fees and disbursements relating to the qualification of the Indenture under the TIA.  The Company shall also reimburse the Investors for the fees and disbursements of Legal Counsel in connection with registration, filing or qualification pursuant to Sections 2 and 3 of this Agreement which amount shall be limited to Ten Thousand United States Dollars ($10,000) for each Registration Statement.  The Company shall pay all of the Investors’ reasonable costs (including fees and disbursements of Legal Counsel) incurred in connection with the successful enforcement of the Investors’ rights under this Agreement.

SECTION 6.Indemnification.  In the event any Registrable Securities are included in a Registration Statement under this Agreement:

(a)To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Investor, the directors, officers, members, partners, employees, agents, representatives thereof, and each Person, if any, who controls any Investor within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or several, (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the Commission, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or

11

actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or any amendment (including post-effective amendments) or supplement thereto or in any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which the Registrable Securities are offered (“Blue Sky Filing”), or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if authorized for use by the Company prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if any) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to a Registration Statement, or (iv) any material violation of this Agreement by the Company (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”).  Subject to Section 6(c) of this Agreement, the Company shall reimburse the Indemnified Persons, 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 investigating or defending any such Claim.  Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a) and the agreement with respect to contribution contained in Section 7 of this Agreement:  (i) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person or its legal counsel expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto; (ii) shall not be available to the extent such Claim is based on a failure of the Investor to deliver or to cause to be delivered the prospectus made available by the Company, including a corrected prospectus, if such prospectus or corrected prospectus was timely made available by the Company pursuant to Section 3(d) of this Agreement; and (iii) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.  Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9 of this Agreement.

(b)In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to severally and not jointly indemnify, hold harmless and defend, to the same extent and in the same manner as is set forth in Section 6(a) of this Agreement, the Company, each of its directors, each of its officers who signs the Registration Statement, its agents and each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Party”), against any Claims or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claims or Indemnified Damages arise out of or are based upon any Violation (including for purposes of this paragraph, a material violation of this Agreement by the Investor), in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by

12

such Investor or its legal counsel expressly for use in connection with such Registration Statement and, subject to Section 6(c) of this Agreement, such Investor will reimburse any legal or other expenses reasonably incurred by an Indemnified Party in connection with investigating or defending any such Claim; provided, however, that the indemnification agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 of this Agreement shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld or delayed; provided, further, that the Investor shall be liable under this Section 6(b) for only that amount of the Claims and Indemnified Damages as does not exceed the net proceeds to such Investors as a result of the sale of Registrable Securities giving rise to such liability.  Such indemnification agreement shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9 of this Agreement.  Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented.

(c)Promptly after an Indemnified Person or Indemnified Party under this Section 6 has knowledge of any Claim as to which such Indemnified Person or Indemnified Party reasonably believes indemnity may be sought or promptly after such Indemnified Person or Indemnified Party receives notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of such Claim, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding; provided, further, that the indemnifying party shall not be responsible for the reasonable fees and expense of more than one (1) separate legal counsel for such Indemnified Person or Indemnified Party.  In the case of an Indemnified Person, the legal counsel referred to in the immediately preceding sentence shall be selected by the Investors holding at least a majority in interest of the Registrable Securities included in the Registration Statement to which the Claim relates.  The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or Claim.  The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto.  No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent; provided, however, that the indemnifying party shall not

13

unreasonably withhold, delay or condition its consent.  No indemnifying party shall, without the prior written consent of the Indemnified Party or Indemnified Person, 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 Indemnified Party or Indemnified Person of a full release from all liability in respect to such Claim and action and proceeding.  After indemnification as provided for under this Agreement, the rights of the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made.  The failure to deliver written notice to the indemnifying party as provided in this Agreement shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

(d)No Person involved in the sale of Registrable Securities who is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such sale shall be entitled to indemnification from any Person involved in such sale of Registrable Securities who is not guilty of fraudulent misrepresentation.

(e)The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred.

(f)The indemnification agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

SECTION 7.Contribution.  To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 of this Agreement to the fullest extent permitted by law; provided, however, that:  (i) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 6 of this Agreement, (ii) no Person involved in the sale of Registrable Securities who is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such sale shall be entitled to contribution from any Person involved in such sale of Registrable Securities who is not guilty of fraudulent misrepresentation, and (iii) contribution by any seller of Registrable Securities shall be limited in amount to the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to Section 6 or this Section 7 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.  The provisions of this Section 7 shall remain in full force and effect, regardless of the investigation made by or on behalf of the beneficiaries of this Section 7 and shall survive the transfer of Registrable Securities by the Investors pursuant to Section 9 of this Agreement.

14

SECTION 8.Reporting.

(a)Reports Under The Exchange Act.  With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the Commission that may at any time permit the Investors to sell securities of the Company to the public without registration (“Rule 144”), for so long as Registrable Securities remain outstanding, the Company shall use reasonable best efforts to:

(1)make and keep public information available, as those terms are understood and defined in Rule 144;

(2)file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(3)furnish to each Investor, so long as such Investor owns Registrable Securities, promptly upon request, (A) a written statement by the Company, if true, that it has complied with the applicable reporting requirements of Rule 144, the Securities Act and the Exchange Act, (B) a copy of the most recent annual or quarterly report of the Company and copies of such other reports and documents so filed by the Company, and (C) such other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration.

(b)Rule 144A Information. The Company shall, for so long as Registrable Securities remain outstanding, upon request of any Investor, for so long as such Investor owns Registrable Securities, make available to such Investor the information required by Rule 144A(d)(4) (or any successor rule) under the Securities Act.

SECTION 9.Assignment of Registration Rights.  The rights under this Agreement shall be automatically assignable by the Investors to any transferee of all or any portion of such Investor’s Registrable Securities if:  (i) the Investor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment; (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (a) the name and address of such transferee or assignee, and (b) the securities with respect to which such rights are being transferred or assigned; (iii) immediately following such transfer or assignment, the further disposition of such securities by the transferee or assignee is restricted under the Securities Act and applicable state securities laws; (iv) at or before the time the Company receives the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the obligations of an Investor under this Agreement; (v) such transfer shall have been made in accordance with the applicable requirements of the Securities Purchase Agreement, the Indenture and the Notes; and (vi) such transfer shall have been conducted in accordance with all applicable federal and state securities laws.

15

SECTION 10.Amendment of Registration Rights.  Any provision of this Agreement may be amended and the observance of any provision of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Investors who then hold at least a majority of the Conversion Shares, determined as if all of the Notes held by Investors then outstanding have been converted into Conversion Shares without regard to any limitations on conversion of the Notes; provided that for theses purposes any Securities owned directly or indirectly by the Company or any of its affiliates shall be deemed not to be outstanding.  Notwithstanding the preceding sentence to the contrary no amendment or waiver of the provisions of Section 9 or this Section 10 shall be effective without the approval of all Investors holding Conversion Shares.  Any amendment or waiver effected in accordance with this Section 10 shall be binding upon each Investor and the Company.  No such amendment shall be effective to the extent that it applies to less than all of the holders of the Registrable Securities.  No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration also is offered to all of the parties to this Agreement.

SECTION 11.Miscellaneous.

(a)A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable Securities.  If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from such record owner of such Registrable Securities.

(b)Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered:  (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (evidenced by mechanically or electronically generated receipt by the sender’s facsimile machine); or (iii) one (1) Business Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same.  The addresses and facsimile numbers for such communications shall be:

SECURITIES PURCHASE AGREEMENT

THIS SECURITIES PURCHASE AGREEMENT (the “Agreement”), dated as of February 9, 2005, by and among Quixote Corporation, a Delaware corporation (the “Company”), and the Buyers listed on the Schedule of Buyers attached hereto as Exhibit A (individually, a “Buyer” and, collectively, the “Buyers”).

THE PARTIES TO THIS AGREEMENT enter into this Agreement on the basis of the following facts, intentions and understandings:

A.In accordance with the terms and conditions of this Agreement, the Company has agreed to issue and sell, and the Buyers have severally agreed to purchase in the aggregate, Forty Million United States Dollars ($40,000,000) principal amount of the Company’s 7% Convertible Senior Subordinated Notes due 2025 (such Convertible Senior Notes, substantially in the form attached as Exhibit A to the Indenture (as defined below), as such form of Note may be amended, modified or supplemented from time to time in accordance with the terms thereof, the “Notes”), which shall be convertible into shares of the common stock, $0.01²/₃ par value per share (the “Common Stock”), of the Company (as converted, the “Conversion Shares”). The Notes will be issued pursuant to an Indenture, dated as of February 9, 2005 (the “Indenture”) by and between the Company and LaSalle Bank National Association, as trustee (the “Trustee”), substantially in the form attached hereto as Exhibit B.

B.Contemporaneously with the execution and delivery of this Agreement, the parties hereto are executing and delivering a Registration Rights Agreement substantially in the form attached hereto as Exhibit D (as the same may be amended, modified or supplemented from time to time in accordance with the terms thereof, the “Registration Rights Agreement”) pursuant to which the Company has agreed to provide the Buyers with the benefit of certain registration rights under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”) and applicable state securities laws, on the terms and subject to the conditions set forth therein.

NOW THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and each of the Buyers hereby agree as follows:

SECTION 1.Purchase and Sale of Notes.

(a)Purchase of Notes.  Subject to the satisfaction (or waiver, to the extent permitted by applicable law) of the conditions set forth in Sections 6 and 7 of this Agreement, the Company shall issue and sell to each Buyer, and each Buyer severally and not jointly agrees to purchase from the Company, the respective principal amount of Notes set forth opposite such Buyer’s name on the Schedule of Buyers attached hereto as Exhibit A (the “Closing”).  The Company shall issue to each Buyer One Thousand United States Dollars ($1,000) principal amount of the Notes for each One Thousand United States Dollars ($1,000) tendered by each such Buyer.

(b)The Closing.  The date and time of the Closing (the “Closing Date”) shall be 10:00 a.m., Chicago, Illinois local time, on February 9, 2005, subject to the satisfaction (or waiver, to the extent permitted by applicable law) of the conditions set forth in Sections 6 and 7 of this

Agreement.  The Closing shall occur on the Closing Date at the offices of Holland & Knight LLP, 131 South Dearborn Street, 30^th Floor, Chicago, Illinois  60603.

(c)Form of Payment.  On the Closing Date, (i) each Buyer shall pay the Company for the Notes to be issued and sold to such Buyer on the Closing Date, by wire transfer of immediately available funds in accordance with the Company’s written wire instructions attached hereto on Schedule A, or through book-entry settlement procedures, as applicable, (ii) the Company shall reimburse each Buyer for its reasonable expenses to the extent required by Section 4(i) of this Agreement, and (iii) the Company shall issue to each Buyer properly authenticated Notes (in the denominations of not less than One Thousand United States Dollars ($1,000) as such Buyer shall reasonably request) representing the principal amount of Notes which such Buyer is then purchasing hereunder, duly executed on behalf of the Company and registered in the name of such Buyer, provided, that Notes eligible for services through The Depository Trust Company (“DTC”) shall be issued, countersigned, registered and delivered in global certificate form through the facilities at DTC in such names and denominations as each Buyer shall specify.

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

2

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.

3

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

4

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,

5

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)

6

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

7

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.

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

8

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, Harris 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

9

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.

10

(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.  Grant Thornton LLP are independent public accountants as required by the Exchange Act.  The Company is not aware of any issues raised by the Commission with respect to any of the SEC Documents that have not been resolved in the ordinary course of review.  No other written information provided by or on behalf of the Company to the Buyers which is not included in the SEC Documents, including, without limitation, information referred to in Section 2(d) of this Agreement, contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are or were made, not misleading.  The Company satisfies the requirements for use of Form S-3 for registration of the resale of the Registrable Securities and does not have any knowledge or reason to believe that it does not satisfy such requirements or have any knowledge of any fact which would reasonably result in its not satisfying such requirements.  The Company is not required to file and will not be required to file, any agreement, note, lease, mortgage, deed or other instrument entered into prior to the date hereof and to which the Company is a party or by which the Company is bound which has not been previously filed as an exhibit to its reports filed with the Commission under the Exchange Act, except for those Transaction Documents required to be filed upon execution and delivery, and the Fourth Amendment to the Senior Facility.  Except for the issuance of the Notes contemplated by this Agreement, no event, liability, development or circumstance has occurred or exists, or is currently contemplated to occur, with respect to the Company or its Subsidiaries or their respective business, properties, prospects, operations or financial condition, that would be required to be disclosed by the Company under applicable securities laws and which has not been publicly disclosed.  The Company has no reason to believe that its independent auditors will withhold their consent to the inclusion of their audit opinion concerning the Company’s financial statements which shall be included in the Registration Statement (as such term is defined in the Registration Rights Agreement).

11

(g)Absence of Litigation.  Except as disclosed in the section titled “Legal Proceedings” in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2004, there is no action, suit, proceeding, inquiry or investigation (“Material Litigation”) before or by any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the Company or any of its Subsidiaries, threatened in writing against the Company or any of its Subsidiaries or any of the Company’s or the Subsidiaries’ officers or directors in their capacities as such that would have a Material Adverse Effect.  The Company believes it has set aside on its books provisions reasonably adequate for the payment of all judgments, damages, costs, and expenses arising out of its pending Material Litigation and has appropriately accounted for such reserves under GAAP.

(h)No Integrated Offering.  Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the Securities Act or any applicable shareholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated, nor will the Company or any of its Subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings.

(i)Intellectual Property Rights.  The Company and its Subsidiaries own, possess, license or can acquire or make use of on reasonable terms, adequate rights or licenses to use all trademarks, trade names, trade dress, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, technology licenses, approvals, governmental authorizations, trade secrets, and other intellectual property rights (collectively, “Intellectual Property”) necessary to conduct their respective businesses as now conducted and as currently contemplated to be conducted by them as described in the SEC Documents, except where the failure to currently own or possess Intellectual Property would not have a Material Adverse Effect.  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.  There is no claim, action or proceeding being made by the Company or its Subsidiaries regarding the Intellectual Property rights of the Company or its Subsidiaries or to the Company’s knowledge, brought or currently threatened against the Company or its Subsidiaries regarding the Intellectual Property rights of or the use of any Intellectual Property by the Company or its Subsidiaries of any third party that, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect.

(j)Insurance.  The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are commensurate with similarly situated companies engaged in similar businesses as the Company and its Subsidiaries.

(k)Regulatory Permits.  The Company and its Subsidiaries possess all material certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as currently conducted

12

(the “Permits”), except where the failure to possess such Permits would not have a Material Adverse Effect, and neither the Company nor any of its Subsidiaries has received any written notice of proceedings relating to the revocation or material modification of any such Permit.

(l)Tax Status.  The Company and each of its Subsidiaries (i) has made or filed all federal and state income and all other tax returns, reports and declarations required by any jurisdiction to which it is subject and all such tax returns are accurate and complete in all material respects, (ii) has paid all taxes and other governmental assessments and charges due with respect to the periods covered by such returns, reports and declarations, except those being contested in good faith and for which the Company has made appropriate reserves on its books in accordance with GAAP, and (iii) has paid or set aside on its books provisions reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or declarations (referred to in clause (i) above) apply.  Except as disclosed in the SEC Documents, there are no unpaid taxes or assessments for tax deficiencies that are individually or in the aggregate material in amount claimed to be due by the taxing authority of any jurisdiction, and the Company knows of no basis for any such claim, and there are no audits in progress with respect to any tax returns, no extension of time is in force with respect to any date on which any tax return was or is to be filed (except for extensions of federal and state tax returns due June 30, 2004 made in the ordinary course of business), and no waiver or agreement is in force for the extension of time for the assessment or payment of any tax.  Except as disclosed in the SEC Documents, all provisions for tax liabilities of the Company and each of its Subsidiaries have been disclosed in the Company’s financial statements and made in accordance with GAAP consistently applied, and all liabilities for taxes of the Company and each of its Subsidiaries attributable to periods prior to or ending on the Closing Date have been adequately disclosed in the Company’s financial statements.

(n)Foreign Corrupt Practices.  Neither the Company nor any of its Subsidiaries, nor, to the Company’s knowledge, any director, officer, agent, employee or other person acting on behalf of the Company or any Subsidiary has, in the course of his actions for, or on behalf of, the Company or any Subsidiary used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; violated or is in violation of any provision of the United States Foreign Corrupt Practices Act of 1977, as amended, or made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic government official or employee.

(o)Confidential Private Placement Memorandum. The information supplied by the Company for inclusion or incorporation by reference in the Confidential Private Placement Memorandum dated as of February 9, 2005 (the “Confidential Private Placement

13

Memorandum”) in connection with the Offering does not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.  If, at any time prior to the Closing Date, any event with respect to the Company shall occur which is required to be described in the Confidential Private Placement Memorandum, such event shall be so described, and an appropriate amendment or supplement shall be prepared by the Company.

(p)Transactions With Affiliates.  Other than the grant of stock options granted pursuant to the Company’s employee benefit plans, none of the officers, directors or employees of the Company is presently a party to any transaction with the Company or any of its Subsidiaries (other than in connection with the provision of services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any such officer, director or employee or, to the knowledge of the Company, any corporation, partnership, trust or other entity in which any such officer, director, or employee has a substantial interest or is an officer, director, trustee or partner, such that the transaction would be required to be disclosed pursuant to Item 404 of Regulation S-K promulgated under the Securities Act.

(q)Brokers and Finders.  Except for fees payable to the Placement Agents as placement agents, no brokers, finders or financial advisory fees or commissions will be payable by the Company with respect to the transactions contemplated by this Agreement.

(r)Absence of Certain Changes.  Except as disclosed in the SEC Documents available on the EDGAR system, since June 30, 2004, there has been no change or development that has had or could reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect.

(s)No Material Non-Public Information.  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 acknowledges and agrees that each Buyer is acting solely in the capacity of arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that no Buyer is (i) an officer or director of the Company, (ii) an “affiliate” of the Company (as defined in Rule 144) or (iii) to the knowledge of the Company, a “beneficial owner” of more than 10% of the Common Stock (as defined for purposes of Rule 13d-3 of the Exchange Act).  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

14

of the Securities.  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.

(u)Dilutive Effect.  The Company understands and acknowledges that the number of Conversion Shares issuable upon conversion of the Notes will increase in certain circumstances.  The Company further acknowledges that its obligation to issue Conversion Shares upon conversion of the Notes in accordance with this Agreement, the Indenture and the Notesis, in each case, absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interests of other shareholders of the Company.

(v)Insolvency.  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).  For purposes of this Section 3(v), “Insolvent” means (i) the present fair saleable value of the Company’s assets is less than the amount required to pay the Company’s total debt, (ii) the Company is unable to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured, (iii) the Company intends to incur or believes that it will incur debts that would be beyond its ability to pay as such debts mature or (iv) the Company has unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted.

(w)Employee Relations.

(1)Except as disclosed in the SEC Documents, neither the Company nor any of its Subsidiaries is a party to any collective bargaining agreement or employs any member of a union.  The Company and its Subsidiaries believe that their relations with their employees are good.  No executive officer of the Company (as defined in Rule 501(f) of the Securities Act) has notified the Company that such officer intends to leave the Company or otherwise terminate such officer’s employment with the Company.  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.

(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.

(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

20

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.

24

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

25

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.  EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

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:

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.

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.

We enclose the following additional documents:

1.A copy of the Securities Purchase Agreement; and

2.A capitalization table listing the Buyers and their respective beneficial ownership interests in the shares of Common Stock.

Please be advised that the Buyers have relied upon this instruction letter as an inducement to enter into the Securities Purchase Agreement and, accordingly, each of the Buyers is a third party beneficiary to these instructions.

Please sign in the space provided below to evidence your acceptance and acknowledgment of your responsibilities under this letter.  Please call me at (312) 705-8410 if you require any further information.  Thank you for your assistance.

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.

QUIXOTE CORPORATION ANNOUNCES COMPLETION OF $40 MILLION
PRIVATE PLACEMENT OF CONVERTIBLE SUBORDINATED NOTES

CHICAGO, IL, February 10, 2005—Quixote Corporation (Nasdaq: QUIX) today announced that effective February 9, 2005 it sold $40 million of 7% Convertible Senior Subordinated Notes due February 15, 2025 in a private placement.

Under the terms of the private placement, the investors may convert the Notes into the Company’s common stock at any time prior to the final maturity date of February 15, 2025.  The conversion price is $25.90 per share, which represents a 40% premium over the closing price of the Company’s stock on February 8, 2005.  If fully converted, the Notes would convert into approximately 1,544,000 shares of the Company’s common stock.  The Notes are fully redeemable by the Company at any time after February 20, 2008 at 100% of the principal amount plus accrued and unpaid interest.   The investors may require the Company to repurchase the Notes in cash at a price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest, if any, on February 15, 2010, 2015 or 2020.  Interest is payable semi-annually on February 15 and August 15 of each year, beginning August 15, 2005.  The Company also agreed to register the Notes and common stock issuable upon conversion of the Notes with the Securities and Exchange Commission within thirty days.  The Company will use the net proceeds from the sale of the Notes to reduce its existing bank debt.

Leslie J. Jezuit, Chairman and Chief Executive Officer of Quixote Corporation, commented, “By strengthening our capital structure, this transaction fits in well with our near and long-term strategic initiatives and operational goals.  The proceeds of this financing will be immediately used to pay down our term and revolving credit facilities with our banks and we expect to renegotiate our bank credit arrangement on more favorable terms to provide us additional financial flexibility.  We believe this will position us well as our market and industry conditions improve.”

The securities are being sold to accredited investors in reliance on Regulation D under the Securities Act of 1933, as amended.  Piper Jaffray & Co. and Harris Nesbitt Corp. served as the exclusive placement agents.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of these securities.  The securities have not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
