(xxiv) Rule 144A Eligibility. The Securities are eligible for resale pursuant to Rule 144A and will not be, at the Closing Time, of the same class as securities listed on a national securities exchange registered under Section 6 of the 1934 Act, or quoted in a U.S. automated interdealer quotation system. (xxv) No General Solicitation. None of the Company, its Affiliates or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company makes no representation) has engaged or will engage, in connection with the offering of the Securities, in any form of general solicitation or general advertising within the meaning of Rule 502(c) under the 1933 Act.

SECTION 2. Sale and Delivery to Initial Purchasers; Closing. (a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Initial Purchaser, severally and not jointly, and each Initial Purchaser, severally and not jointly, agrees to purchase from the Company, at the price set forth in Schedule B, the aggregate principal amount of Initial Securities set forth in Schedule A opposite the name of such Initial Purchaser, plus any additional principal amount of Initial Securities which such Initial Purchaser may become obligated to purchase pursuant to the provisions of Section 11 hereof. (b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Initial Purchasers, severally and not jointly, to purchase up to an additional $50,000,000 in aggregate principal amount of Option Securities at the price set forth in Schedule B. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representative to the Company setting forth the aggregate principal amount of Option Securities as to which the several Initial Purchasers are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a "Date of Delivery") shall be determined by the Representative, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Initial Purchasers, acting severally and not jointly, will purchase that proportion of the total aggregate principal amount of Option Securities then being purchased which the principal amount of Initial Securities set forth in Schedule A opposite the name of such Initial Purchaser bears to the aggregate principal amount of Initial Securities, plus any additional principal amount of Option Securities which such Initial Purchaser may become obligated to purchase pursuant to the provisions of Section 11 hereof, subject in each case to such adjustments as the Representative in its discretion shall make to eliminate any sales or purchases of fractional Securities. (c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Thelen Reid & Priest LLP, counsel for the Initial Purchasers, at 875 Third Avenue, New York, NY or at such other place as shall be agreed upon by the Representative and the Company, at 10:00 A.M. (Eastern time) on the third business day after the date hereof (unless postponed in accordance with the provisions of Section 11), or such other time not later than ten business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called "Closing Time"). In addition, in the event that any or all of the Option Securities are purchased by the Initial Purchasers, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed 10 upon by the Representative and the Company, on each Date of Delivery as specified in the notice from the Representative to the Company. Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Representative for the respective accounts of the Initial Purchasers of certificates for the Securities to be purchased by them. It is understood that each Initial Purchaser has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually and not as representative of the Initial Purchasers, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Initial Purchaser whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Initial Purchaser from its obligations hereunder. (d) Denominations; Registration. Certificates for the Initial Securities and the Option Securities, if any, shall be in such denominations ($1,000 or integral multiples thereof) and registered in such names as the Representative may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Initial Securities and the Option Securities, if any, will be made available for examination and packaging by the Representative in New York, NY not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. (e) Delivery of Global Securities. In lieu of the delivery to the Initial Purchasers of certificates representing the Securities at the Closing Time and on each Date of Delivery, as contemplated above, the Company, with the approval of the Representative, may deliver one or more global Securities to a custodian for The Depository Trust Company ("DTC"), to be held by DTC initially for the accounts of the several Initial Purchasers. SECTION 3. Covenants of the Company. (a) Offering Memorandum. The Company, as promptly as possible, will furnish to each Initial Purchaser, without charge, such number of copies of the Preliminary Offering Memorandum, the Final Offering Memorandum and any amendments and supplements thereto and documents incorporated by reference therein as such Initial Purchaser may reasonably request. (b) Notice and Effect of Material Events. The Company will immediately notify each Initial Purchaser, and confirm such notice in writing, of (x) any filing made by the Company of information relating to the offering of the Securities with any securities exchange or any other regulatory body in the United States or any other jurisdiction, and (y) prior to the completion of the placement of the Securities by the Initial Purchasers as evidenced by a notice in writing from the Initial Purchasers to the Company, any material change in or affecting, or any development which is reasonably likely to result in a material change in or affecting, the condition, financial or otherwise, or the results of operations or business affairs of the Company and its subsidiaries considered as one enterprise which (i) make any statement in the Offering Memorandum false or 11 misleading or (ii) are not disclosed in the Offering Memorandum. In such event or if during such time any event shall occur as a result of which it is necessary, in the reasonable opinion of any of the Company, its counsel, the Initial Purchasers or counsel for the Initial Purchasers, to amend or supplement the Final Offering Memorandum in order that the Final Offering Memorandum not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances then existing, the Company will forthwith amend or supplement the Final Offering Memorandum by preparing and furnishing to each Initial Purchaser an amendment or amendments of, or a supplement or supplements to, the Final Offering Memorandum (in form and substance satisfactory in the reasonable opinion of counsel for the Initial Purchasers) so that, as so amended or supplemented, the Final Offering Memorandum will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered to a Subsequent Purchaser, not misleading. (c) Amendment to Offering Memorandum and Supplements. The Company will advise each Initial Purchaser promptly of any proposal to amend or supplement the Offering Memorandum and will not effect such amendment or supplement without the consent of the Initial Purchasers. Neither the consent of the Initial Purchasers, nor the Initial Purchaser's delivery of any such amendment or supplement, shall constitute a waiver of any of the conditions set forth in Section 5 hereof. (d) Qualification of Securities for Offer and Sale. The Company will use its best efforts, in cooperation with the Initial Purchasers, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions as the Representative may designate and will maintain such qualifications in effect as long as required for the sale of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. (e) DTC. The Company will cooperate with the Representative and use its best efforts to permit the Securities to be eligible for clearance and settlement through the facilities of DTC.

(g) Restriction on Sale of Securities. During a period of 90 days from the date of the Offering Memorandum, the Company will not, without the prior written consent of Merrill Lynch, directly or indirectly, issue, sell, offer or agree to sell, grant any option for the sale of, or otherwise dispose of, any other debt securities of the Company or securities of the Company that are convertible into, or exchangeable for, the Securities or such other debt securities. (h) Restriction on Sale of Common Stock. During a period of 90 days from the date of the Offering Memorandum, the Company will not, without the prior written consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to 12 purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any share of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement 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. The foregoing sentence shall not apply to (A) the Securities to be sold hereunder, (B) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Offering Memorandum, (C) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to any existing employee benefit plan or non-employee director stock plan of the Company referred to or contemplated by the Offering Memorandum or any renewal or extension of such plan as may be approved by the requisite holders of shares of the Company's Common Stock, or (D) any shares of Common Stock issued pursuant to the common stock investment plan. (i) PORTAL Designation. The Company will use its best efforts to permit the Securities to be designated PORTAL securities in accordance with the rules and regulations adopted by the National Association of Securities Dealers, Inc.

SECTION 6. Subsequent Offers and Resales of the Securities. (a) Offer and Sale Procedures. Each of the Initial Purchasers and the Company hereby establish and agree to observe the following procedures in connection with the offer and sale of the Securities: (i) Offers and Sales only to Qualified Institutional Buyers. Offers and sales of the Securities shall only be made to persons whom the offeror or seller reasonably believes to be qualified institutional buyers, as defined in Rule 144A under the 1933 Act ("Qualified Institutional Buyers"). (ii) No General Solicitation. No general solicitation or general advertising (within the meaning of Rule 502(c) under the 1933 Act) will be used in the United States in connection with the offering or sale of the Securities. (iii) Purchases by Non-Bank Fiduciaries. In the case of a non-bank Subsequent Purchaser of a Security acting as a fiduciary for one or more third parties, each third party shall, in the judgment of the applicable Initial Purchaser, be a Qualified Institutional Buyer. (iv) Subsequent Purchaser Notification. Each Initial Purchaser will take reasonable steps to inform, and cause each of its U.S. Affiliates to take reasonable steps to inform, persons acquiring Securities from such Initial Purchaser or affiliate, as the case may be, in the United States that the Securities (A) have not been and will not be registered under the 1933 Act, (B) are being sold to them without registration under the 1933 Act in reliance on Rule 144A or in accordance with another exemption from registration under the 1933 Act, as the case may be, and (C) may not be offered, sold or otherwise transferred except (1) to the Company or its subsidiaries, (2) outside the United States in accordance with Regulation S under the 1933 Act ("Regulation S"), or (3) inside the United States in accordance with (x) Rule 144A to a person whom the seller reasonably believes is a Qualified Institutional Buyer that is purchasing such Securities for its own account or for the account of a Qualified Institutional Buyer to whom notice is given that the offer, sale or transfer is being made in reliance on Rule 144A or (y) pursuant to another available exemption from registration under the 1933 Act. (v) Minimum Principal Amount. No sale of the Securities to any one Subsequent Purchaser will be for less than U.S. $100,000 principal amount and no Security will be issued in a smaller principal amount. If the Subsequent Purchaser is a non-bank fiduciary acting on behalf of others, each person for whom it is acting must purchase at least U.S. $100,000 principal amount of the Securities. (vi) Restrictions on Transfer. The transfer restrictions and the other provisions set forth in the Offering Memorandum under the heading "Notice to Investors", including the legend required thereby, shall apply to the Securities except as otherwise agreed by the Company and the Initial Purchasers. 17 (vii) Delivery of Offering Memorandum. Each Initial Purchaser will deliver to each purchaser of the Securities from such Initial Purchaser, in connection with its original distribution of the Securities, a copy of the Offering Memorandum, as amended and supplemented at the date of such delivery. (b) Covenants of the Company. The Company covenants with each Initial Purchaser as follows: (i) Integration. The Company agrees that it will not and will cause its Affiliates not to, directly or indirectly, solicit any offer to buy, sell or make any offer or sale of, or otherwise negotiate in respect of, securities of the Company of any class if, as a result of the doctrine of "integration" referred to in Rule 502 under the 1933 Act, such offer or sale would render invalid (for the purpose of (i) the sale of the Securities by the Company to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the 1933 Act provided by Section 4(2) thereof or by Rule 144A or Regulation S thereunder or otherwise. (ii) Rule 144A Information. The Company agrees that, in order to render the Securities eligible for resale pursuant to Rule 144A under the 1933 Act, while any of the Securities remain outstanding, it will make available, upon request, to any holder of Securities or prospective purchasers of Securities the information specified in Rule 144A(d)(4), unless the Company furnishes information to the Commission pursuant to Section 13 or 15(d) of the 1934 Act. (iii) Restriction on Repurchases. Until the expiration of two years after the original issuance of the Securities, the Company will not, and will cause its Affiliates not to, resell any Securities which are "restricted securities" (as such term is defined under Rule 144(a)(3) under the 1933 Act), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the ordinary course of business in unsolicited broker's transactions). (c) Qualified Institutional Buyer. Each Initial Purchaser severally and not jointly represents and warrants to, and agrees with, the Company that it is a Qualified Institutional Buyer. (d) Resale Pursuant to Rule 144A. Each Initial Purchaser understands that the Securities have not been and will not be registered under the 1933 Act and may not be offered or sold except pursuant to an exemption from the registration requirements of the 1933 Act. Each Initial Purchaser severally represents and agrees, that, except as permitted by Section 6(a) above, it has offered and sold Securities and will offer and sell Securities only in accordance with Rule 144A under the 1933 Act or another applicable exemption from the registration requirements of the 1933 Act. (e) Additional Representations and Warranties of Initial Purchasers. Each Initial Purchaser severally represents and agrees that it has not entered and will not enter into any 18 contractual arrangements with respect to the distribution of the Securities, except with its affiliates or with the prior written consent of the Company. SECTION 7. Indemnification. (a) Indemnification of Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows: (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company; and (iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser through Merrill Lynch expressly for use in the Offering Memorandum (or any amendment thereto) and provided, further, that this indemnity agreement shall not inure to the benefit of any Initial Purchaser or any person who controls such Initial Purchaser on account of any such loss, liability, claim, damage or expense arising out of any such defect or alleged defect in any Preliminary Offering Memorandum if a copy of the Final Offering Memorandum (exclusive of the documents incorporated by reference therein) shall not have been given or sent by such Initial Purchaser with or prior to the written confirmation of the sale involved to the extent that (i) the Final Offering Memorandum would have cured such defect or alleged defect and (ii) sufficient quantities of the Final Offering Memorandum were timely made available to such Initial Purchaser. 19 (b) Indemnification of Company. Each Initial Purchaser severally agrees to indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Offering Memorandum in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through Merrill Lynch expressly for use in the Offering Memorandum. (c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No 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 litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. SECTION 8. Contribution. If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any 20 losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Initial Purchasers on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Initial Purchasers, bear to the aggregate initial offering price of the Securities. The relative fault of the Company on the one hand and the Initial Purchasers on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Initial Purchasers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased and sold by it hereunder exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 21 For purposes of this Section, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Initial Purchaser, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Initial Purchasers' respective obligations to contribute pursuant to this Section are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint. SECTION 9. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the Initial Purchasers. SECTION 10. Termination of Agreement. (a) Termination; General. The Representative may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Offering Memorandum (exclusive of any supplement thereto), any material adverse change, or any development which is reasonably likely to result in a material adverse change, in the condition, financial or otherwise, or in the results of operations or business affairs of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the NASDAQ National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (iv) if a banking moratorium has been declared by either Federal or New York authorities. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 7, 8 and 9 shall survive such termination and remain in full force and effect. 22 SECTION 11. Default by One or More of the Initial Purchasers. If one or more of the Initial Purchasers shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other initial purchasers, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then: (a) if the principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased hereunder, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Initial Purchasers, or (b) if the principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased hereunder, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser. No action taken pursuant to this Section shall relieve any defaulting Initial Purchaser from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, either the Representative or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Offering Memorandum or in any other documents or arrangements. As used herein, the term "Initial Purchaser" includes any person substituted for an Initial Purchaser under this Section. SECTION 12. Notices.

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

(15) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign is necessary or required in connection with the due authorization, execution and delivery by the Company of the Purchase Agreement, the performance by the Company of its obligations thereunder or the consummation by the Company of the transactions contemplated thereby including, without limitation, the execution and delivery by the Company of the Indenture, the Pledge Agreement, the Control Agreement and the Registration Rights Agreement and the performance by the Company of its obligations thereunder, the offering, sale, issuance or delivery by the Company of the Securities and the issuance and delivery by the Company of Common Stock upon conversion of Securities, or for the consummation by the Company of all other transactions contemplated by the Offering Memorandum, except such as (A) have been obtained, (B) are contemplated in the Registration Rights Agreement and (C) may be required under state securities laws. (16) It is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers and to each Subsequent Purchaser in the manner contemplated by the Purchase Agreement and the Offering Memorandum to register the Securities under the 1933 Act or to qualify the Indenture under the Trust Indenture Act. (17) The execution, delivery and performance of the Purchase Agreement, the Indenture, the Pledge Agreement, the Control Agreement and the Registration Rights Agreement, the consummation of the transactions contemplated in the Purchase Agreement and in the Offering Memorandum (including the offering, sale, issuance and delivery of the Securities and the use of the proceeds from the sale of the Securities as described in the Offering Memorandum under the caption "Use Of Proceeds" and the issuance and delivery of shares of Common Stock upon conversion of Securities) and the performance by the Company of its obligations under the Purchase Agreement, the Indenture, the Pledge Agreement, the Control Agreement or the Registration Rights Agreement or on the Securities do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined in Section 1(a)(xiv) of the Purchase Agreement) under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Significant Subsidiary thereof pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument, known to us, to which the Company or any of its Significant Subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any Significant Subsidiary thereof is subject (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not have a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any of its Significant Subsidiaries, or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us of any government, A-3 government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its Significant Subsidiaries or any of their respective properties, assets or operations. (18) The Company is not an "investment company" or an entity "controlled" by an "investment company," as such terms are defined in the 1940 Act. (19) The Company is a "holding company" under the 1935 Act, but, pursuant to Section 3(a)(1) of the 1935 Act, is exempt from all provisions of the 1935 Act except Section 9(a)(2) thereof. (20) To the best of our knowledge, there are no pending or threatened actions, suits, proceedings, inquiries or investigations, to which the Company or any subsidiary is a party, or to which the property of the Company or any subsidiary thereof is subject, before or brought by any court or governmental agency or body, which, singly or in the aggregate, might reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to materially and adversely affect the consummation of the transactions contemplated in the Purchase Agreement or the performance by the Company of its obligations thereunder or the transactions contemplated by the Offering Memorandum. (21) Nothing has come to our attention that would lead us to believe that the Offering Memorandum or any amendment or supplement thereto (except for financial statements and schedules and other financial data included or incorporated by reference therein or omitted therefrom as to which we need make no statement), at the time the Offering Memorandum was issued, at the time any such amended or supplemented Offering Memorandum was issued or at the Closing Time, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. ALLOCATION OF OPINIONS OF COUNSEL FOR THE COMPANY A. Choate, Hall & Stewart will make all the statements set forth above relying on Woodburn and Wedge as to the matters governed by or relating to the law of the State of Nevada. B. Woodburn & Wedge will make the statements set forth in paragraphs 1, 2, 4, 5, 6, 7, 10, 15 and 17 to the extent the matters set forth therein are governed by or relate to the law of the State of Nevada or instruments governed thereby, or relate to the State of Nevada or agencies thereof. In addition, Woodburn and Wedge will state, in customary fashion, their belief that a Nevada court, or a federal court applying Nevada choice of law principles, would give effect to the choice of law provisions of the Indenture and the Securities.
