Any certificate signed by any officer of the Company and delivered to the Representative or counsel for the Underwriter in connection with the offering of the Securities shall be deemed a representation and warranty by the Company, as to matters covered thereby, to the Underwriter. 2. Purchase and Sale. (a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to sell to the Underwriter, and the Underwriter agrees to purchase from the Company, at the purchase price set forth in Schedule I hereto the principal amount of the Securities set forth opposite the Underwriter's name in Schedule I hereto. (b) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company hereby grants an option to the Underwriter to purchase up to $28,500,000 aggregate principal amount of Option Notes at the same percentage of the principal amount thereof as the Underwriter shall pay for the Firm Notes, plus accrued interest, in any, from May 26, 2006 to the settlement date (the "settlement date") for the Option Notes.

Delivery and Payment. Delivery of and payment for the Firm Notes and the Option Notes (if the option provided for in Section 2(b) hereof shall have been exercised on or before the third Business Day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on the date set forth in Schedule I hereto, or at such time on such later date not more than three Business Days after the foregoing date as the Representative shall designate, which date and time may be postponed by agreement between the Representative and the Company (such date and time of delivery and payment for the Securities being herein called the "Closing Date"). Delivery of the Securities shall be made to the Representative for the account of the Underwriter against payment by the Underwriter of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company.

If settlement for the Option Notes occurs after the Closing Date, the Company will deliver to the Representative on the settlement date for the Option Notes, and the obligation of the Underwriter to purchase the Option Notes shall be conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6 hereof. 4. Offering by Underwriter. It is understood that the Underwriter proposes to offer the Securities for sale to the public as set forth in the Final Prospectus. 5. Agreements. The Company agrees with the Underwriter that: (a) Prior to the termination of the offering of the Securities, the Company will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form reasonably approved by the Representative with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representative of such timely filing. During the time when the Final Prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), the Company will promptly advise the Representative (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of 15 objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable best efforts if applicable to have such amendment or new registration statement declared effective as soon as practicable. (b) It will prepare a final term sheet, containing solely a description of the pricing terms applicable to the Securities and information derived therefrom, in a form approved by you and to file such term sheet pursuant to Rule 433(d) within the time required by such Rule. (c) If, at any time prior to the filing of a final prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, the Company will (i) notify promptly the Representative so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request. (d) If, at any time when the Final Prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company promptly will (i) notify the Representative of such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) if applicable, use its reasonable best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request. (e) As soon as practicable, the Company will make generally available to its security holders and to the Representative an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158. 16 (f) If requested by the Representative, the Company will furnish to the Representative and counsel for the Underwriter, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representative may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering. (g) The Company will arrange, if necessary, for the qualification of the Securities and Conversion Shares for sale under the laws of such jurisdictions as the Representative may reasonably designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the National Association of Securities Dealers, Inc. in connection with its review of the offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject. (h) The Company agrees that, unless it has obtained or will obtain the prior written consent of the Representative, and the Underwriter agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a "free writing prospectus" (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than the information contained in the final term sheet prepared and filed pursuant to Section 5(b) hereto; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II hereto. Any such free writing prospectus consented to by the Representative or the Company is hereinafter referred to as a "Permitted Free Writing Prospectus." The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. (i) During a period of 90 days from the date of the Final Prospectus, the Company will not, without the prior written consent of Citigroup Global Markets Inc., (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any 17 share of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file, or cause to be filed, any registration statement or prospectus under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; provided, however, that (i) the Company may issue and sell Common Stock pursuant to any employee stock option plan, stock ownership plan or dividend reinvestment plan of the Company in effect at the Execution Time and (ii) the Company may issue Common Stock issuable upon the conversion of the Securities or the exercise of warrants outstanding at the Execution Time. (j) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities. (k) Prior to the Closing Date, the Company will not issue any press release or other public communication directly or indirectly or hold any press conference with respect to the Company, its condition, financial or otherwise, or earnings, business affairs or business prospects (except for routine oral marketing communications in the ordinary course of business and consistent with the past practices of the Company and of which the Representative is notified), without consultation with the Representative, unless in the judgment of the Company and its counsel, and after notification to the Representative, such press release or public communication is required by law. (l) The Company will apply the net proceeds from the sale of the Securities as set forth in the Disclosure Package and the Prospectus under the heading "Use of Proceeds". (m) In connection with the offering of the Securities, until the earlier to occur of (i) the date the Representative shall have notified the Company of the completion of the resale of the Securities or (ii) 30 days following the Closing Date, the Company will make its officers, employees, independent accountants and legal counsel reasonably available upon request by the Representative. (n) The Company will not take any action prior to the execution and delivery of the Indenture which, if taken after such execution and delivery, would have violated any of the covenants contained in the Indenture. 18 (o) The Company will reserve and keep available at all times free of pre-emptive rights, the full number of Conversion Shares issuable upon conversion of the Securities. (p) Between the date hereof and the later of the Closing Date and any settlement date relating to Option Notes, the Company will not do or authorize anything that would result in an adjustment of the Conversion Price. (q) The Company will use all reasonable efforts to effect the designation or listing subject to notice of issuance, of the Conversion Shares issuable upon such conversion on the Nasdaq National Market or on such market or exchange on which the Common Stock is then quoted or listed. (r) The Company agrees with the Representative to pay (a) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities to the Underwriter or pursuant to the sale of the Securities to the public as set forth in the Disclosure Package and Final Prospectus, and for the issuance of the Conversion Shares, and any transfer or other taxes payable in that connection; (b) the costs incident to the preparation, printing and distribution of any Preliminary Prospectus and the Final Prospectus and any amendments and exhibits thereto, the costs of printing, reproducing and distributing the Transaction Documents and applicable related documents by mail, telex or other means of communications; (c) any applicable listing or other fees; (d) any fee of the National Association of Securities Dealers, Inc. in connection with its review of the offering; (e) all fees and expenses of the Trustees or any agent thereof; (f) any fees charged by securities rating services for rating the Securities; and (g) all other costs and expenses incident to the performance of the obligations of the Company under this Agreement (including, without limitation, the fees and expenses of the Company's counsel and the Company's independent accountants); provided that, except as otherwise provided in this paragraph and in Section 7, the Underwriter shall pay its own costs and expenses, including the fees and expenses of its counsel. 6. Conditions to the Obligations of the Underwriter. The obligation of the Underwriter to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Execution Time and the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions: (a) The Final Prospectus, and any supplement thereto, have been filed in the manner and within the time period required by Rule 424(b); the final term sheet contemplated by Section 5(b) hereto, and any other material required to be filed by the Company pursuant to Rule 433(d) under the Act, shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433; and no stop order suspending the effectiveness of the 19 Registration Statement or any notice objecting to its use shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

In rendering such opinion, such counsel may rely as to matters involving the application of laws of any jurisdiction other than the United States or the corporate laws of the State of Delaware, to the extent he deems proper and specifies in such opinion, upon the opinion of other counsel of good standing whom he believes to be reliable and who are satisfactory to counsel for the Underwriter. Such opinion may also contain customary qualifications and limitations.

Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. 7. Reimbursement of Underwriter's Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriter set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriter, the Company will reimburse the Underwriter on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been reasonably incurred by the Underwriter in connection with the proposed purchase and sale of the Securities. 8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless the Underwriter, the directors, officers, employees and agents of the Underwriter and each person who controls the Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged 24 untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriter through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. (b) The Underwriter agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriter, but only with reference to written information relating to the Underwriter furnished to the Company by or on behalf of the Underwriter through the Representative specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Underwriter may otherwise have. The Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and, under the heading "Underwriting" or "Plan of Distribution", (i) the sentences related to concessions and reallowances and (iii) the paragraph related to stabilization, syndicate covering transactions in any Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by the Underwriter for inclusion in any Preliminary Prospectus or the Final Prospectus. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any 25 event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel reasonably shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties, which firm shall be designated in writing by Citigroup Global Markets Inc., if the indemnified parties under this Section consist of the Underwriter indemnified party, or by the Company if the indemnified parties under this Section consist of any Company indemnified parties. Each indemnified party, as a condition of the indemnity agreements contained in paragraphs (a) and (b) of this Section, shall use all reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. No indemnifying party shall be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing, if an indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential 26 parties to such claim or action), such settlement, compromise or consent shall include an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriter severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and the Underwriter may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriter on the other from the offering of the Securities; provided, however, that in no case shall the Underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by the Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriter severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriter on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriter shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriter on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls the Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of the Underwriter shall have the same rights to contribution as the Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same 27 rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). 9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Company's Common Stock shall have been suspended by the Commission or the Nasdaq National Market or trading in securities generally on the New York Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on such Exchange or the Nasdaq National Market, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any supplement thereto). 10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 11. Notices.

No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm's-length commercial transaction between the Company, on the one hand, and the Underwriter and any affiliate through which it may be acting, on the other, (b) the Underwriter is acting as principal and not as an agent or fiduciary of the Company and (c) the Company's 28 engagement of the Underwriter in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Underwriter has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owes an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. 14. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriter, or any of them, with respect to the subject matter hereof. 15. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 16.

The following information updates and supersedes the information in our Prospectus Supplement (the "Prospectus Supplement"), Subject to Completion dated May 10, 2006, To Prospectus Dated May 10, 2006. In addition, the information set forth below under "Capitalization" supersedes and replaces in its entirety the information set forth in the Prospectus Supplement under the caption "Capitalization." UPDATE ON OFFERING SIZE We are offering $190.0 million aggregate principal amount (with an additional $28.5 million should the underwriter's option to purchase additional notes be fully exercised) of 2.50% Convertible Senior Subordinated Notes due 2011. USE OF PROCEEDS We expect to receive net proceeds from this offering of $183.9 million (excluding the underwriter's option to purchase additional notes), after deducting the underwriting discounts and commissions and our estimated offering expenses. We intend to use the net proceeds from the offering to redeem, repurchase or otherwise retire $176.5 million of our $200.0 million aggregate principal amount outstanding of our 10.5% senior subordinated notes due 2009 (together with the payment of the related premium, accrued and unpaid interest to and including the redemption date and related fees and expenses). In the event the underwriter exercises its option to purchase additional notes in full, we intend to use the proceeds to redeem, repurchase or otherwise retire the remaining amount of notes outstanding of our 10.5% senior subordinated notes due 2009, with any remainder (an estimated $3.2 million), to retire other debt or for general corporate or working capital purposes. UPDATE ON CONCURRENT OFFERING SIZE AND USE OF PROCEEDS We are offering $400.0 million aggregate principal amount of our 9.25% senior notes due 2016 in the concurrent offering. We intend to use the net proceeds from the concurrent offering to purchase the $349.4 million of 9.25% senior notes in the tender offer (including the payment of the tender premium, accrued and unpaid interest, the early tender payment and related fees and expenses), with the remainder (an estimated $13.1 million) to repurchase remaining 9.25% senior notes that may be tendered, subject to the cap, to retire other debt or for general corporate or working capital purposes. As of May 9, 2006, holders of $349.4 million in aggregate principal amount of 9.25% notes have tendered in the tender offer. We have increased the size of the tender offer to $360 million. OUTSTANDING DEBT AND RANKING As of March 31, 2006, assuming completion of the concurrent transactions, we would have had approximately $1,464.8 million of senior debt (approximately $300 million of which would have been secured), $213.5 million of senior subordinated debt and approximately $378.4 million of subordinated debt. 2 SETTLEMENT CYCLE We expect that delivery of the notes will be made against payment therefor on or about May 26, 2006, which will be the 11th business day following the date of pricing of the notes (such settlement cycle being herein referred to as "T + 11)"). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, or Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or the next seven succeeding business days will be required, by virtue of the fact that the notes initially will settle T + 11, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of pricing or the next three succeeding business days should consult their own advisor. 3 CAPITALIZATION The following table sets forth our cash and cash equivalents and total capitalization as of March 31, 2006 (1) on a historical basis, and (2) as adjusted to give effect to the concurrent transactions, as follows: - the issuance in this offering of $190.0 million of convertible subordinated notes for net proceeds of $183.9 million and the application thereof to redeem $176.5 million aggregate principal amount outstanding of our 10.5% senior subordinated notes, and - the issuance of $400.0 million of senior notes in the concurrent offering for net proceeds of $391.8 million and the application thereof to repurchase $349.4 million aggregate principal amount of our 9.25% notes in the tender offer. You should read the as adjusted capitalization data set forth in the table below in conjunction with "Selected Consolidated Financial Data," "Description of Certain Indebtedness," and "Management's Discussion and Analysis of Financial Condition and Results of Operations," set forth in our Annual Report on Form 10-K for the year ended December 31, 2005 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2006, and our consolidated financial statements and the notes thereto, incorporated by reference into the Prospectus Supplement.

- --------------- (1) As of March 31, 2006, we had utilized $2.5 million of the available letter of credit sub-limit, and had $97.5 million available under this facility. (2) Pursuant to the terms of the indenture governing these notes, we have the right to redeem the notes at a price of 101.75% plus accrued and unpaid interest to and including the redemption date. For purposes of this table, we have assumed that such notes are redeemed on the 60th day following this offering at that price. The actual amount of 10.5% senior subordinated notes repurchased will depend on market conditions and the actual price at which we may redeem, repurchase or otherwise retire these notes. 4 (3) Total stockholders' equity as of March 31, 2006, as adjusted, reflects an approximate $27.7 million early debt extinguishment charge consisting of $23.2 million of prepayment premiums and $4.5 million for the write-off of unamortized debt issue costs. The issuer has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov.
