Ladies and Gentlemen:

Introductory. Broadwing Corporation, a Delaware corporation (the “Company”), proposes to issue and sell to Jefferies & Co., Inc. (“Jefferies”) and CIBC World Markets Corp. (“CIBC” and, together with Jefferies, the “Initial Purchasers”), severally and not jointly $150,000,000 aggregate principal amount of the Company’s 3.125% Convertible Senior Debentures due 2026 (the “Firm Debentures”). In addition, the Company has granted to the several Initial Purchasers an option to purchase up to $30,000,000 aggregate principal amount of the Company’s 3.125% Convertible Senior Debentures due 2026 (the “Option Debentures”), as provided in Section 2. The Firm Debentures and, if and to the extent such option is exercised, the Option Debentures are collectively called the “Debentures.” The Debentures will be unconditionally guaranteed as to the payment of principal, interest, liquidated damages, if any (the “Guarantees”) by each of the Company’s existing domestic subsidiaries listed on Schedule I hereto (the “Guarantors”) and certain subsequently acquired or organized domestic subsidiaries. The Debentures and the Guarantees are to be issued pursuant to an indenture (the “Indenture”), to be dated as of the Closing Date (as defined below), among the Company, the Guarantors party thereto and ▇.▇. ▇▇▇▇▇▇ Trust Company, National Association, as trustee (the “Trustee”).

The Debentures will be convertible into shares of the Company’s common stock, $0.01 par value per share (the “Common Stock”), in accordance with the terms of the Debentures and the Indenture, at an initial ratio of 60.241 shares per $1,000 principal amount of Debentures, representing an initial conversion price of approximately $16.60 per share.

The holders of Debentures will be entitled to the benefits of a Registration Rights Agreement (the “Registration Rights Agreement”), pursuant to which the Company and the Guarantors party thereto will file a shelf registration statement with the Securities and Exchange Commission (the “Commission”) registering resales of the Debentures and the shares of Common Stock issuable upon conversion thereof (the “Conversion Shares”) under the Securities Act of 1933, as amended (the “Securities Act”).

The Company understands that the Initial Purchasers propose to make an offering of the Debentures on the terms and in the manner set forth herein and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Debentures to purchasers (“Subsequent Purchasers”) at any time after the date of this Agreement. The Debentures are to be offered and sold through the Initial Purchasers without being registered under the Securities Act, in reliance upon exemptions therefrom. Pursuant to the terms of the Debentures and the Indenture, investors that acquire Debentures may only resell or otherwise transfer such Debentures if such Debentures are hereinafter registered under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A (“Rule 144A”) and Regulations S (“Reg S”) of the rules and regulations promulgated under the Securities Act by the Commission).

The Company and the Guarantors have prepared and will deliver to the Initial Purchasers (A) on the date hereof or the next succeeding business day, copies of a final offering memorandum (the “Offering Memorandum”) for use by the Initial Purchasers in connection with their offering of the Debentures. “Offering Memorandum” means, with respect to any date or time referred to in this Agreement, the most recent offering memorandum (whether the Offering Memorandum, or any amendment or supplement to such document), including the documents incorporated therein by reference, which has been prepared and delivered by the Company to the Initial Purchasers in connection with their offering of the Debentures, (B) on or prior to the date hereof the preliminary offering memorandum dated May 8, 2006 (the “Preliminary Offering Memorandum” and together with the pricing terms to Subsequent Purchasers set forth on the final terms sheet attached as Schedule II hereto, the “Disclosure Package”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described” or “stated” in the Disclosure Package and the Offering Memorandum (or other references of like import) shall be deemed to mean and include any document filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is incorporated by reference in the Disclosure Package and the Offering Memorandum.

The Company hereby confirms its agreements with the Initial Purchasers as follows:

Section 1. Representations and Warranties of the Company. The Company hereby represents, warrants and covenants to each of the several Initial Purchasers as of the date hereof and as of the Closing Date and as of the Option Closing Date (as defined below), if any, as follows:

(a) Subsidiaries. The Company has no direct or indirect Subsidiaries (the “Subsidiaries”) other than those listed in the Disclosure Package and the Offering Memorandum. Except as disclosed in the Form 10-K or in Schedule III, the Company owns, directly or indirectly, the capital stock or comparable equity interests of each Subsidiary free and clear of any lien, charge, claim, security interest, encumbrance, right of first refusal or other restriction (collectively, “Liens”) and all the issued and outstanding shares of capital stock or comparable equity interest of each Subsidiary are validly issued and are fully paid, non-assessable and free of preemptive and similar rights.

(b) Organization and Good Standing of the Company and its Subsidiaries. Each of the Company and the Subsidiaries is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization (as applicable), with the requisite power and authority to own and use its properties and assets and to carry on its business as described in the Disclosure Package and the Offering Memorandum. Neither the Company nor any Subsidiary is in violation of any of the provisions of its respective certificate or articles of incorporation, bylaws or other organizational or charter documents. Each of the Company and the Subsidiaries is duly qualified to do business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate, (i) adversely affect the legality, validity or enforceability of this Agreement, the Indenture, the Registration Rights Agreement, the Debentures and the Guarantees, as applicable (collectively, the “Transaction Documents”), (ii) reasonably be expected to have or result in a material adverse effect on the results of operations, assets, business or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole on a consolidated basis, or (iii) adversely impair the Company’s ability to perform fully on a timely basis its obligations under any of the Transaction Documents (any of (i), (ii) or (iii), a “Material Adverse Effect”).

(c) Capitalization and Other Capital Stock Matters. Upon issuance and delivery of the Debentures and the Guarantees in accordance with this Agreement and the Indenture, the Debentures will be convertible at the option of the holder thereof into shares of Common Stock; the Conversion Shares have been duly authorized and reserved for issuance upon such conversion by all necessary corporate action and such Conversion Shares when issued upon such conversion will be validly issued, fully paid and non-assessable. Neither the offering nor sale of the Debentures and the Guarantees as contemplated by this Agreement gives rise to any rights, other than those which have been waived or satisfied, for or relating to the registration under the Securities Act of any shares of Common Stock except pursuant to the Registration Rights Agreement.

As of March 31, 2006, the outstanding capital stock of the Company consists of 87,155,664 shares, 87,155,664 shares of which are common stock, $0.01 par value per share, and zero shares of which are preferred stock, $0.01 par value per share. As of March 31, 2006, the authorized capital stock of the Company consists of 1,900,000,000 shares of common stock and 200,000,000 shares of preferred stock. As of December 31, 2005, there were 74,038,257 shares of common stock issued and outstanding. There were no shares of preferred stock outstanding on March 31, 2006. Except as disclosed in the SEC Reports (as defined below), there has been no material change in the Company’s capitalization since March 31, 2006. All outstanding shares of capital stock are duly authorized, validly issued, fully paid and nonassessable and have been issued in compliance with all applicable securities laws. Except as disclosed in the Disclosure Package there are no outstanding options, warrants, script rights to subscribe to, calls or commitments of any character whatsoever relating to, or securities, rights or obligations convertible into or exercisable or exchangeable for, or giving any Person any right to subscribe for or acquire, any shares of Common Stock, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock, or securities or rights convertible or exchangeable into shares of Common Stock. Except as disclosed in Schedule IV, the issue and sale of the Debentures will not obligate the Company to issue shares of Common Stock or other securities to any person (other than the Initial Purchasers upon conversion of the Debentures) and will not result in a

right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under such securities. To the knowledge of the Company, except as specifically disclosed in the proxy statement for the Company’s annual meeting of stockholders held on May 12, 2006, no person or group of related persons beneficially owns (as determined pursuant to Rule 13d-3 under the Exchange Act), or has the right to acquire, by agreement with or by obligation binding upon the Company, beneficial ownership of in excess of 5% of the outstanding Common Stock, ignoring for such purposes any limitation on the number of shares of Common Stock that may be owned at any single time.

The information set forth under the caption “Capitalization” in the Disclosure Package and the Offering Memorandum is true and correct in all material respects. The Debentures, the Guarantees, the Indenture, the Registration Rights Agreement and the Conversion Shares conform in all material respects to the descriptions thereof contained in the Disclosure Package and the Offering Memorandum.

(d) Distribution of Offering Material by the Company. The Disclosure Package, as of the Applicable Time (as defined below) did not contain any untrue statement of 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, not misleading; the Offering Memorandum, as of its date and as of the Closing Date did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the Disclosure Package or the Offering Memorandum or any such amendment or supplement, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Initial Purchasers, specifically for use in the preparation thereof. The documents incorporated or deemed to be incorporated by reference in the Disclosure Package and the Offering Memorandum at the time they were or hereafter are filed with the Commission complied and will comply in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder (the “Exchange Act Regulations”).

(q) Internal Control Over Financial Reporting. The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that complies with the requirements of the Exchange Act. The Company’s internal control over financial reporting is effective and the Company is not aware of any material weaknesses in its internal control over financial reporting.

The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged. Neither the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business.

(u) ERISA Compliance. Except as otherwise disclosed in the Disclosure Package and the Offering Memorandum, the Company and its Subsidiaries and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its Subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or a Subsidiary, any member of any group of organizations described in Sections 414(b),(c),(m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such Subsidiary is a member.

Neither the Company, its Subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by the Company, its Subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

(v) No Labor Disturbance. No labor or employment dispute exists or, to the knowledge of the Company, is imminent or threatened, with respect to any of the employees or consultants of the Company that has, or could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(w) Compliance with Environmental Laws. Except as described in the Disclosure Package and the Offering Memorandum and except as would not, singly or in the aggregate, result in a Material Adverse Effect, (i) neither the Company nor any of its Subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation,

ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (ii) the Company and its Subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (iii) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its Subsidiaries and (iv) there are no events or circumstances that might reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or any of its Subsidiaries relating to Hazardous Materials or any Environmental Laws.

Neither the Company nor the Guarantors nor, to the knowledge of the Company and the Guarantors, any director, officer, agent, employee or other person associated with or acting on behalf of the Company or the Guarantors has (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; or (iii) made any bribe, rebate, payoff, influence, payment, kickback or other unlawful payment.

(y) Compliance with Federal Reserve Regulations. Neither the Company nor any of the Subsidiaries owns any “margin securities” as that term is defined in Regulations G and U of the Board of Governors of the Federal Reserve System ( the “Federal Reserve Board”), and none of the proceeds of the sale of the Debentures will be used, directly or indirectly, for the purpose of purchasing or carrying any margin security, for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry any margin security or for any other purpose which might cause any of the Debentures to be considered a “purpose credit” within the meanings of Regulation G, T, U or X of the Federal Reserve Board.

(z) Authority. The Company and the Guarantors have the requisite corporate or limited liability company power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents to which they are a party and otherwise to carry out their obligations hereunder and thereunder.

(bb) Indenture. The Indenture has been duly authorized by the Company and the Guarantors party thereto and, when executed and delivered by the Company, the Guarantors party thereto and the Trustee, will constitute a valid and binding agreement of the Company and the Guarantors party thereto, enforceable against the Company and the Guarantors party thereto in accordance with its terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting

The Debentures have been duly authorized and at the Closing Date, when executed by the Company, authenticated by the Trustee in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of this Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms except enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and equitable principles of general applicability (regardless of whether enforcement is considered in a proceeding in equity or at law) and will be entitled to the benefits of, the Indenture and the Registration Rights Agreement.

The Guarantees have been duly authorized and at the Closing Date, when executed by the Guarantors, authenticated by the Trustee in accordance with the terms of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of this Agreement, will constitute valid and binding obligations of the Guarantors, enforceable against the Guarantors in accordance with their terms except enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or similar laws affecting enforcement of creditors’ rights generally and equitable principles of general applicability (regardless of whether enforcement is considered in a proceeding in equity or at law) and will be entitled to the benefits of, the Indenture and the Registration Rights Agreement.

regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a Subsidiary is subject (including federal and state securities laws and regulations and the rules and regulations of any self-regulatory organization to which the Company or its securities are subject), or by which any property or asset of the Company or a Subsidiary is bound or affected.

(gg) No Solicitations; Private Placement. Neither the Company, the Guarantors nor any of their respective affiliates, as such term is defined in Rule 501(b) of Regulation D under the Securities Act (each an “Affiliate”), has directly or indirectly, solicited any offers to buy, sold or offered to sell any security under circumstances that would require the Debentures or the Conversion Shares to be registered under the Securities Act. None of the Company, the Guarantors, their Affiliates or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the Company and the Guarantors make no representation) has engaged or will engage in any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D under the Securities Act. Assuming the accuracy of the Initial Purchasers’ representations and warranties set forth in Section 2 and compliance with the procedures set forth in Section 7 hereof, it is not necessary in connection with the offer, sale issuance and delivery of the Debentures and the Guarantees to the Initial Purchasers and the offer, resale and delivery of the Debentures by the Initial Purchasers in the manner contemplated by this Agreement, the Disclosure Package and the Offering Memorandum to register the Debentures under the Securities Act or to qualify the Indenture under the Trust Indenture Act.

(hh) No Securities of the Same Class. The Debentures are eligible for resale pursuant to Rule 144A and Reg S and will not be, at the Closing Date, of the same class as securities listed on a national securities exchange registered under Section 6 of the Exchange Act, or quoted in a U.S. automated interdealer quotation system.

(ii) Related Party Transactions. Except as set forth in the SEC Reports, none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company, is presently a party to any transaction with the Company or any Subsidiary (other than for services as employees, officers and directors) exceeding $60,000, 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 officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner.

The Company and the Guarantors acknowledge that the Initial Purchasers and, for purposes of the opinions to be delivered pursuant to Section 5 hereof, counsel to the Company and the Guarantors and counsel to the Initial Purchasers, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

Section 2. Purchase, Sale and Delivery of the Debentures.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company and the Guarantors agree to sell to the Initial Purchasers, and the Initial Purchasers agree, severally and not jointly, to purchase from the Company the aggregate principal amount of Firm Debentures set forth opposite their names on Schedule V at the purchase price of 96.875% of the principal

amount of the Firm Debentures (and the Guarantees thereof) (the “Purchase Price”) plus accrued interest if any from the Closing Date.

(b) Payment of the Purchase Price for the Firm Debentures to be sold hereunder is to be made in immediately available funds via wire transfer to the order of the Company for the Debentures to be sold by it against delivery of certificates therefor to the Initial Purchasers. Such delivery is to be made at the offices of ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, New York, New York at 9:00 a.m., EST time, on May 16, 2006 or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” (As used herein, “business day” means a day on which each of the New York Stock Exchange and the Nasdaq National Market is open for trading and on which banks in New York are open for business and not permitted by law or executive order to be closed.) Upon delivery of the Purchase Price, one or more global securities representing the Debentures shall be registered by the Trustee in the name of the nominee of The Depositary Trust Company (“DTC”), Cede & Co., credited to the respective accounts of each of the Initial Purchasers and deposited with the Trustee as custodian for DTC on the Closing Date.

(c) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company and the Guarantors hereby grant to the Initial Purchasers an option to purchase, severally and not jointly, pro rata (in the same proportion as each Initial Purchaser is obligated to purchase the Firm Debentures), any or all of the Option Debentures (and the Guarantees thereof) at the Purchase Price. The option granted hereby may be exercised in whole or in part by Jefferies giving written notice to the Company setting forth the aggregate principal amount of Option Debentures as to which the Initial Purchasers are exercising the option and the time and date for delivery of and payment for such Option Debentures. The time and date at which certificates for Option Debentures are to be delivered shall be determined by Jefferies but shall not be later than 30 days from and including the Closing Date, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. Jefferies may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company. To the extent, if any, that the option is exercised, payment for the Option Debentures shall be made on the Option Closing Date in immediately available funds via wire transfer to the order of the Company for the Option Debentures against delivery of Debentures therefor.

(d) It is understood that each Initial Purchaser will offer and sell the Debentures in accordance with this Section 2 as soon as that Initial Purchaser deems it advisable to do so. The Debentures are to be initially offered at the offering price set forth in the Disclosure Package and Offering Memorandum. Each Initial Purchaser may from time to time thereafter change the price and other selling terms.

(e) Each Initial Purchaser severally and not jointly understands and acknowledges that the Debentures and the Conversion Shares have not been and will not be registered under the Securities Act (except as contemplated by the Registration Rights Agreement) and may not be offered or sold, except in compliance with the registration requirements of the Securities Act or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. Accordingly, each Initial Purchaser severally and not jointly agrees that it will offer and sell the Debentures only to

persons that it reasonably believes to be qualified institutional buyers as defined in Rule 144A under the Securities Act and outside the United States to “Non-U.S. Persons” as defined in Reg S under the Securities Act.

(f) Each Initial Purchaser severally and not jointly agrees that neither it nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (as those terms are used in Rule 502(c) of Regulation D under the Securities Act) in connection with any offer or sale of the Debentures in the United States.

(g) Each Initial Purchaser severally and not jointly represents and warrants to, and agrees with, the Company and the Guarantors that it is a “qualified institutional buyer” within the meaning of Rule 144A (a “QIB”) and an “accredited investor” within the meaning of Rule 501(a) under the Securities Act.

Section 3. Covenants of the Company and the Guarantors. The Company and the Guarantors further covenant and agree with the Initial Purchasers as follows:

(a) Blue Sky Compliance. The Company will cooperate with the Initial Purchasers in endeavoring to qualify the Debentures for sale under the securities laws of such jurisdictions as the Initial Purchasers may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose; provided that the Company and the Guarantors shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company and the Guarantors will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Initial Purchasers may reasonably request for distribution of the Debentures.

(b) Delivery of Offering Memoranda. The Company and the Guarantors will deliver to, or upon the order of, the Initial Purchasers, from time to time, as many copies of the Preliminary Offering Memorandum and the Offering Memorandum as the Initial Purchasers may reasonably request, including documents incorporated by reference therein, and of all amendments thereto, as the Initial Purchasers may reasonably request.

(c) Amendments and Supplements to the Offering Memoranda and Other Securities Act Matters. The Company will immediately notify the Initial Purchasers, and confirm such notice in writing, of (i) any filing made by the Company of information with any securities exchange or any other regulatory body in the United States or any other jurisdiction until such time as the placement of the Debentures by the Initial Purchasers is complete, as evidenced by a notice in writing from the Initial Purchasers that is promptly provided to the Company, and (ii) prior to the completion of the placement of the Debentures by the Initial Purchasers as evidenced by a notice in writing from the Initial Purchasers that is promptly provided to the Company, any material changes in or affecting the condition, financial or otherwise, or the earnings, business affairs or business prospects of the Company, the Guarantors and their respective subsidiaries, considered as one enterprise, which (x) make any statement in the Disclosure Package or the Offering Memorandum false or misleading or (y) are not disclosed in the Disclosure Package or 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 Disclosure Package or the Offering Memorandum in

order that the Disclosure Package or the 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 Disclosure Package or the Offering Memorandum by preparing and furnishing to the Initial Purchasers an amendment or amendments of, or a supplement or supplements to, the Disclosure Package or the Offering Memorandum (in form and substance reasonably satisfactory to Jefferies) so that, as so amended or supplemented, the Disclosure Package or the 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.

(d) Offers; Solicitations. The Company and the Guarantors represent and agree that, unless they obtain the prior consent of Jefferies, they have not made and will not make any offer relating to the Debentures by means of any “individual written communication” (within the meaning of the Securities Act) prepared by or on behalf of the Company or the Guarantors, or used or referred to by the Company, that constitutes an offer to sell or a solicitation of an offer to buy the Debentures other than the Disclosure Package and the Offering Memorandum or amendments or supplements thereto, including, without limitation, any road show relating to the Debentures that constitutes such a written communication.

(e) Amendments to Offering Memoranda. The Company and the Guarantors will advise the Initial Purchasers promptly of any proposal to amend or supplement the Disclosure Package and the Offering Memorandum and will not effect such amendment or supplement without the consent of Jefferies, which consent shall not be unreasonably withheld. Neither the consent of Jefferies nor the Initial Purchasers’ delivery of any such amendment or supplement, shall constitute a waiver of any of the conditions set forth in Section 5 hereof.

(f) Depositary Trust Company. The Company and the Guarantors will cooperate with the Initial Purchasers and use its reasonable best efforts to permit the Debentures to be eligible for clearance and settlement through the facilities of DTC.

(g) Use of Proceeds. The Company and the Guarantors will use the proceeds of the Debentures in compliance with the credit facility and in the manner specified in the Disclosure Package and Offering Memorandum under “Use of Proceeds.”

(h) Reports. For as long as the Debentures are outstanding or a period of four (4) years from the Closing Date, whichever is shorter, the Company will deliver to the Initial Purchasers copies of annual reports and copies of all other documents, reports and information furnished by the Company to its stockholders generally or filed with any securities exchange pursuant to the requirements of such exchange or with the Commission pursuant to the Securities Act or the Exchange Act. The Company will deliver to the Initial Purchasers similar reports with respect to significant subsidiaries, as that term is defined in the Securities Act, if any, which are not consolidated in the Company’s financial statements. The Company shall be deemed to be in compliance with the delivery obligations pursuant to this Section 3(h) by publicly filing such information via the Commission’s Electronic Data Gathering and Retrieval System.

(i) Other Securities. No offering, sale, short sale, issuance or other disposition of any shares of Common Stock of the Company or other securities convertible into or exchangeable or exercisable for shares of Common Stock or derivative of Common Stock (or agreement for such) will be made for a period of 30 days after the date of this Agreement, directly or indirectly, by the Company otherwise than hereunder or with the prior written consent of Jefferies except for (i) options granted in the ordinary course of business under the Company’s employee or director stock option plans, (ii) shares of Common Stock issued or options to purchase shares of Common Stock granted pursuant to the Company’s stock option, stock bonus or other stock plan or employee benefit plan or dividend or investment plan existing as of the date hereof, (iii) the sale of Debentures (and the Guarantees thereof) under this Agreement, (iv) issuance of the Conversion Shares or (v) the filing of the shelf registration statement in respect of the Debentures and the Conversion Shares or any registration statement in respect of any employee, officer or director stock option or other benefit plan existing as of the date hereof.

(j) PORTAL^SM. The Company and the Guarantors will use their reasonable best efforts to permit the Debentures to be designated PORTAL^SM-eligible securities in accordance with the rules and regulations adopted by the NASD relating to the PORTAL^SM Market.

(k) Shares of Common Stock. The Company will reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to satisfy any obligations to issue Common Stock upon conversion of the Debentures.

(l) Nasdaq National Market. The Company will use its reasonable best efforts to cause all shares of Common Stock issuable upon conversion of the Debentures to be listed on the Nasdaq National Market.

(m) Exchange Act. The Company and the Guarantors will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the Exchange Act Regulations.

(n) Investment Company Act. The Company and the Guarantors shall not invest, or otherwise use the proceeds received by the Company and the Guarantors from the sale of the Debentures in such a manner as would require the Company or any of the Guarantors to register as an investment company under the 1940 Act.

(o) Transfer Agent. For so long as any Debenture is outstanding, the Company will continue to maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

(p) No Stabilization; Manipulation. The Company and the Guarantors will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

Section 4. Payment of Expenses. The Company and the Guarantors will pay all costs, expenses and fees incident to the performance of the obligations of the Company and the Guarantors under this Agreement, including, without limiting the generality of the foregoing, the following: (a) accounting fees of the Company and the Guarantors; (b) the fees and

disbursements of counsel for the Company and the Guarantors; (c) the cost of preparing, printing and delivering to, or as requested by, the Initial Purchasers copies of the Disclosure Package, Offering Memorandum, this Agreement, the Indenture, the Registration Rights Agreement and any other documents that may be required in connection with the offering, purchase, sale, issuance or delivery of the Debentures (and the Guarantees thereof); (d) the qualification of the Debentures under securities laws in accordance with the provisions of Section 3(a) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Initial Purchasers in connection therewith and in connection with the preparation of the Blue Sky Survey, any supplement thereto and any Legal Investment Survey (subject to the limitations set forth in the Engagement Letter between the Initial Purchasers and the Company, dated April 9, 2006); (e) the fees and expenses of the Trustee, including the reasonable fees and disbursements of counsel for the Trustee in connection with the Indenture and the Debentures (and the Guarantees thereof); (f) any fees payable in connection with the initial and continued designation of the Debentures as PORTAL^SM securities under the PORTAL^SM Market pursuant to NASD Rule 5322; and (g) the listing fee of the Nasdaq National Market relating to the Conversion Shares. Any transfer taxes imposed on the sale of the Debentures to the Initial Purchasers will be paid by the Company and the Guarantors. The Company and the Guarantors, however, shall not be required to pay for any of the Initial Purchasers’ expenses (other than those related to clause (d) above) except that, if this Agreement shall not be consummated because this Agreement is terminated by the Initial Purchasers pursuant to Section 10 hereof, or by reason of any failure, refusal or inability on the part of the Company or the Guarantors to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof, unless such failure to satisfy said condition or to comply with said terms be due to the default or omission of the Initial Purchasers, then the Company and the Guarantors shall reimburse the Initial Purchasers for reasonable out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Debentures or in contemplation of performing their obligations hereunder; but the Company and the Guarantors shall not in any event be liable to the Initial Purchasers for damages on account of loss of anticipated profits from the sale by the Initial Purchasers of the Debentures.

(ii) The Company and the Guarantors agree that for so long as any of the Debentures are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, it will make available, upon request, to any holder of Debentures or prospective purchasers of

Section 8. Indemnification.

(a) Indemnification of the Initial Purchasers. The Company and the Guarantors agree to indemnify and hold harmless each Initial Purchaser, its directors, officers, employees and agents, and each person, if any, who controls that Initial Purchaser within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which any Initial Purchaser or such director, officer, employee, agent or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package or the Offering Memorandum, or any amendment 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; provided that the Company and the Guarantors shall not be liable under this Section 8(a) to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by any Initial Purchaser through its bad faith or willful misconduct; and to reimburse the Initial Purchasers and each such director, officer, employee, agent or controlling person for any and all expenses (including the fees and disbursements of counsel chosen by Jefferies) as such expenses are reasonably incurred by the Initial Purchasers or such director, officer, employee, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Initial Purchasers expressly for use in the Disclosure Package or the Offering Memorandum, any Preliminary Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by the Initial Purchasers to the Company consists of the information described in subsection (b) below. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company and the Guarantors may otherwise have.

(b) Indemnification of the Company and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and the Guarantors, each of their respective directors, officers, employees and agents and each person, if any, who controls the Company and the Guarantors within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company and the Guarantors, or any such director, officer, employee,

agent or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Disclosure Package or the Offering Memorandum (or any amendment or supplement thereto), or arises out of or is 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, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Disclosure Package or the Offering Memorandum (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Initial Purchasers expressly for use therein; and to reimburse the Company and the Guarantors, or any such director, officer, employee, agent or controlling person for any legal and other expense reasonably incurred by the Company and the Guarantors, or any such director, officer, employee, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company and the Guarantors hereby acknowledge that the only information that the Initial Purchasers have furnished to the Company and the Guarantors expressly for use in the Disclosure Package or the Offering Memorandum (or any amendment or supplement thereto) are (A) the names of the Initial Purchasers and (B) the statements set forth in the third and thirteenth paragraphs under the caption “Plan of Distribution” in the Offering Memorandum. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that the Initial Purchasers may otherwise have.

(c) Notifications and Other Indemnification Procedures. 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 an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 8 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or 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, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred

by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party, representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding.

Section 9. Contribution. If the indemnification provided for in Section 8 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Debentures (and the Guarantees thereof) pursuant to this Agreement or (ii) if the allocation provided by clause (i) above 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 and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Debentures (and the Guarantees thereof) pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Debentures (and the Guarantees thereof) pursuant to this Agreement (before deducting expenses) received by the Company and the Guarantors, and the total discounts and commissions received by the Initial Purchasers, in each case as set forth on the front cover page of the Offering Memorandum bear to the aggregate initial public offering price of the Debentures as set forth on such cover. The relative fault of the Company

and the Guarantors, 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 and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8(c) for purposes of indemnification.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding the provisions of this Section 10, the Initial Purchasers shall not be required to contribute any amount in excess of the discounts and commissions received by the Initial Purchasers in connection with the Debentures purchased by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 10, each officer and employee and each person, if any, who controls any Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as that Initial Purchaser, and each director, employee and person, if any, who controls the Company or any Guarantor or an with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and such Guarantor.

Section 10. Termination of this Agreement. Prior to the Closing Date this Agreement may be terminated by any Initial Purchaser by notice given to the Company if at any time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the Nasdaq National Market, New York Stock Exchange, or trading in securities generally on the New York Stock Exchange or the American Stock Exchange or the Nasdaq National Market shall have been suspended or limited (other than limitations on hours or numbers of days trading), or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the National Association of Securities Dealers, Inc.; (ii) a general banking moratorium shall have been declared by federal or New York authorities; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in your judgment is material and adverse and makes it impracticable or inadvisable to market the Shares in the manner and on the terms described in the Disclosure Package and the Offering Memorandum or to enforce contracts for the sale of securities. Any termination pursuant to this Section 10 shall be without liability on the part of the Company to the Initial Purchasers.

Termination of this Agreement pursuant to this Section 10 shall be without liability of any party to the other party except as provided in Section 6 hereof.

Section 11. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Guarantors, of their officers and of the Initial Purchasers 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 Initial Purchasers, the Company or the Guarantors or any of its or their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Debentures (and the Guarantees thereof) sold hereunder and any termination of this Agreement.

Section 13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the controlling persons referred to in Section 8 and Section 9, and in each case their respective successors, and no other person will have any

right or obligation hereunder. The term “successors” shall not include any purchaser of the Debentures as such from the Initial Purchasers merely by reason of such purchase.

Section 14. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

Section 15. Defaulting Initial Purchaser. If any Initial Purchaser shall fail or refuse to purchase Debentures that it has agreed to purchase hereunder on the Closing Date or any Option Closing Date, and the aggregate number of Debentures which such defaulting Initial Purchaser agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Debentures to be purchased on such date, the other Initial Purchaser shall be obligated to purchase the Debentures which such defaulting Initial Purchaser agreed but failed or refused to purchase on such date. If any Initial Purchaser shall fail or refuse to purchase Debentures and the aggregate number of Debentures with respect to which such default occurs exceeds 10% of the aggregate number of Debentures to be purchased on such date, and arrangements satisfactory to the non-defaulting Initial Purchaser and the Company for the purchase of such Debentures are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the non-defaulting Initial Purchaser or the Company shall have the right to postpone the Closing Date or Option Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Offering Memorandum or any other documents or arrangements may be effected.

Section 16. Governing Law Provisions. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed in such state. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the Borough of Manhattan in the City of New York or the courts of the State of New York in each case located in the Borough of Manhattan in the City of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified

Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

Section 17. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Table of Contents and the Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 8 and the contribution provisions of Section 9, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Sections 8 and 9 hereto fairly allocate the risks in light of the ability of the parties to investigate the Company and the Guarantors, their affairs and their business in order to assure that adequate disclosure has been made in the Disclosure Package or the Offering Memorandum (and any amendments and supplements thereto), as required by the Securities Act and the Exchange Act.

RE:	Broadwing Corporation (the “Company”)

Ladies and Gentlemen:

The undersigned is an owner of record or beneficially of certain shares (the “Shares”) of the Company’s common stock, $.01 par value per share (the “Common Stock”) or securities convertible into or exchangeable or exercisable for Common Stock. The Company proposes to carry out an offering (the “Offering”) of approximately $150,000,000 aggregate principal amount of its Convertible Senior Debentures due 2026, which will be convertible into shares of Common Stock, for which you will act as the initial purchasers. The undersigned recognizes that the Offering will be of benefit to the undersigned and will benefit the Company. The undersigned acknowledges that you are relying on the representations and agreements of the undersigned contained in this letter in carrying out the Offering and in entering into the purchase agreement with the Company and certain of its subsidiaries with respect to the Offering.

In consideration of the foregoing, the undersigned hereby agrees that the undersigned will not (and will cause any spouse or immediate family member of the spouse or the undersigned living in the undersigned’s household not to), without the prior written consent of Jefferies & Company, Inc. (which consent may be withheld in its sole discretion), directly or indirectly, sell, offer, contract or grant any option to sell (including without limitation any short sale), pledge, transfer, establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, or otherwise dispose of any Shares, options or warrants to acquire Shares, or securities exchangeable or exercisable for or convertible into Shares currently or hereafter owned either of record or beneficially (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) by the undersigned (or such spouse or family member), or publicly announce an intention to do any of the foregoing, for a period commencing on the date hereof and continuing through the close of trading on the date 30 days after the date on which the shelf registration statement filed by the Company pursuant to Rule 415 under the Securities Act of 1933, as amended, becomes effective covering the registration and resale of the debentures, shares issuable upon conversion of the debentures and the guarantees, effective. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of Shares or securities convertible into or exchangeable or exercisable for Shares held by the undersigned except in compliance with the foregoing restrictions.

Notwithstanding the foregoing, the undersigned may transfer any Shares or securities convertible into or exchangeable or exercisable for the Shares (i) for the purpose of satisfying any tax liabilities that accrue upon the vesting of restricted stock issued by the Company (ii) related to the sale or other disposition of Common Stock or other securities pursuant to the terms of a pre-existing trading plan, as in effect on the date hereof, established under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, and (iii) either (y) during the undersigned’s lifetime to his or her immediate family or to a trust if the beneficiaries of such trust are exclusively the undersigned and/or a member or members of his or

B-1

her immediate family or (z) upon death by will or intestacy; provided, however, that prior to any such transfer pursuant to this clause (iii) each transferee shall execute an agreement substantially identical to this agreement and which shall be satisfactory to ▇▇▇▇▇▇▇▇▇ & Company, Inc., pursuant to which each transferee shall agree to receive and hold such Shares, or securities convertible into or exchangeable or exercisable for the Shares, subject to the provisions hereof, and there shall be no further transfer by any such transferee except in accordance with the provisions hereof. For purposes of clause (iii) above, “immediate family” shall mean spouse, lineal descendant, father, mother, brother, sister or domestic partner of the transferor, whether by law or otherwise, or any grandparent, mother-in-law, father-in-law, daughter-in-law, brother-in-law, stepchild, grandchild or step-grandchild, uncle, aunt, niece or nephew of the transferor, and which shall include adoptive relationships.

Notwithstanding anything to the contrary contained herein, if the Offering is not completed by May 26, 2006, this agreement shall automatically terminate.
