(i) the representations and warranties of the Company in this Agreement that are qualified as to materiality are true and correct and all other representations and warranties of the Company in this Agreement are true and correct in all material respects on and as of the Closing Date with the same effect as if made on the Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date;

(h) At the time of execution of this Agreement and at the Closing Date, the Company shall have requested and caused KPMG LLP to furnish to the Representatives letters, dated respectively as of the time of execution of this Agreement and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent registered accountants within the meaning of the Securities Act and the Exchange Act and the respective applicable rules and regulations adopted by the Commission thereunder and that they have performed a review of the unaudited interim financial information of the Company for the three-month period ended March 31, 2006, and as at March 31, 2006, in accordance with Statement on Auditing Standards No. 100, and stating in effect that:

(i) in their opinion the audited financial statements and financial statement schedules and pro forma financial statements included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the

Final Prospectus and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Securities Act and the Exchange Act and the related rules and regulations adopted by the Commission;

(ii) on the basis of a reading of the latest unaudited financial statements made available by the Company and its subsidiaries; their limited review, in accordance with the standards established under Statement on Auditing Standards No. 100, of the unaudited interim financial information for the three-month period ended March 31, 2006, and as at March 31, 2006; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the stockholders, directors and audit and compensation committees of the Company and the Subsidiaries; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company and its subsidiaries as to transactions and events subsequent to December 31, 2005, nothing came to their attention which caused them to believe that:

(A)

any unaudited financial statements included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus do not comply as to form in all material respects with applicable accounting requirements of the Securities Act and with the related rules and regulations adopted by the Commission with respect to financial statements included or incorporated by reference in quarterly reports on Form 10-Q under the Exchange Act; and said unaudited financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus; or

(B)

with respect to the period subsequent to March 31, 2006, there were any changes, at a specified date not more than five days prior to the date of the letter, in the long-term debt of the Company and its subsidiaries or capital stock of the Company or decreases in the stockholders’ equity of the Company as compared with the amounts shown on the March 31, 2006 consolidated balance sheet included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus, or for the period from April 1, 2006 to such specified date there were any increases, as compared with the corresponding period in the preceding quarter, in net loss or loss from continuing operations before income taxes or in total or per share

amounts of net income/loss of the Company and its subsidiaries, except in all instances for changes or increases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representatives; or

(C)

the information included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus in response to Regulation S-K, Item 301 (Selected Financial Data), Item 302 (Supplementary Financial Information) and Item 402 (Executive Compensation) is not in conformity with the applicable disclosure requirements of Regulation S-K; and

(iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its subsidiaries) set forth in the Registration Statement, the Preliminary Prospectus and the Final Prospectus and in Exhibit 12 to the Registration Statement, including the information set forth under the captions “Summary” (other than with respect to financial information of TelCove, Inc. (“TelCove”)), “Risk Factors”, “Use of Proceeds”, “Capitalization”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (other than with respect to financial information of TelCove) and “Business” in the Final Prospectus, the information included or incorporated by reference in Items 1, 2, 6, 7, 11, 12 and 13 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus, and the information included in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included or incorporated by reference in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2006 incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation; and

(iv) they have read the unaudited pro forma financial statements included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Final Prospectus (the “pro forma financial statements”); carried out certain specified procedures; inquiries of certain officials of the Company who have responsibility for financial and accounting matters; and proved the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the pro forma financial statements, and the officials of the Company referred to above have stated, in response to such auditor’s inquiries, that all significant assumptions regarding the business combinations have been reflected in the pro forma adjustments and that the unaudited

condensed consolidated financial statements referred to herein comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X.

All references in this Section 6(h) to the Registration Statement, the Preliminary Prospectus and the Final Prospectus shall be deemed to include any amendment or supplement thereto at the date of the applicable letter.

(i) At the time of execution of this Agreement, the Company shall have requested and caused PricewaterhouseCoopers LLP to furnish to the Representatives a letter, dated as of the time of execution of this Agreement, in form and substance reasonably satisfactory to the Representatives, confirming that they are independent certified accountants with respect to WilTel under Rule 101 of the Code of Professional Conduct of the American Institute of Certified Public Accountants and its rulings and interpretations, that they have performed a review of the unaudited interim financial information of WilTel for the nine-month period ended September 30, 2005, and as at September 30, 2005, in accordance with SAS No. 100, Interim Financial Information, and stating in effect that on the basis of a reading of the latest unaudited financial statements made available by WilTel and its subsidiaries; their limited review, in accordance with the standards established under SAS No. 100, Interim Financial Information, of the unaudited interim financial information for the nine-month period ended September 30, 2004, and as at September 30, 2005; and carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter, except as noted therein, nothing came to their attention which caused them to believe that any unaudited financial statements included or incorporated by reference in the Preliminary Prospectus and the Final Prospectus are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included or incorporated by reference in the Preliminary Prospectus and the Final Prospectus. All references in this Section 6(i) to the Preliminary Prospectus and the Final Prospectus shall be deemed to include any amendment or supplement thereto at the date of the letter.

(j) Subsequent to the time of execution of this Agreement or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto), there shall not have been (i) any increase, change or decrease specified in the letter or letters referred to in paragraph (h) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the properties, business, results of operations, financial condition, affairs or business prospects of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof), the

Disclosure Package and the Final Prospectus (in each case exclusive of any supplement thereto).

(k) Subsequent to the time of execution of this Agreement, there shall not have been (i) any decrease in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Securities Act) or (ii) any notice given of any intended or potential decrease in any such rating or that such organization has under surveillance or review (other than any such notice with positive implications of a possible upgrading) its rating of the Company’s or any Subsidiary’s debt securities.

(l) The Securities shall have been listed and admitted and authorized for trading, subject to official notice of issuance, on the Nasdaq National Market, and reasonably satisfactory evidence of such actions shall have been provided to the Representatives.

(m) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancelation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Cravath, Swaine & Xxxxx LLP, counsel for the Underwriters, at 000 Xxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, in each case, other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through Xxxxxxx Xxxxx on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. Except as provided in the preceding sentence or elsewhere in this Agreement, the Underwriters shall be responsible for all costs and expenses incurred by them in connection with their purchase of the Securities hereunder and the resale of any of the Securities, including, without limitation, their own out-of-pocket lodging, meal and other “roadshow” expenses and fees and disbursements of counsel for the Underwriters and such other “roadshow” expenses as shall be agreed upon by the Company and the Representatives.

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Basic Prospectus, any preliminary prospectus (including the Preliminary Prospectus), the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet prepared and filed pursuant to Section 5(b) hereof, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that (i) the list of Underwriters and their respective participation in the sale of the Securities, (ii) the sentences related to concessions, discounts and reallowances, (iii) the paragraphs related to stabilization, syndicate covering transactions and penalty bids, (iv) the representations relating to offerings in the European Union, including the United Kingdom, and (v) the paragraph related to electronic distributions of the prospectus supplement under the heading “Underwriting” in the Preliminary Prospectus and the Final Prospectus, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus or the Final Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party

of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. It is understood, however, that the Company shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Underwriters and controlling persons, which firm shall be designated in writing by Xxxxxxx Xxxxx. An indemnifying party shall not be liable under this Section 8 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by such indemnifying party, which consent shall not be unreasonably withheld.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as

may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering of the Securities (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase, in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24 hour period, then the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such

nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company, except as provided in Section 11 hereof. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding seven Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in any of the Company’s securities shall have been suspended by the Commission or the Nasdaq National Market or trading in securities generally on the New York Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on such Exchange or the Nasdaq National Market, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters 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 any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7, 8 and 14 hereof shall survive the termination or cancelation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriters, will be mailed, delivered or sent by fax and confirmed to them, care of Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, at Xxxxxxx Xxxxx World Headquarters, North Tower, World Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000-0000; or, if sent to the Company, will be mailed, delivered or sent by fax and confirmed to it at 0000 Xxxxxxxx Xxxxxxxxx, Xxxxxxxxxx, Xxxxxxxx 00000, attention: General Counsel.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand,

and the several Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York (without regard to the conflict of law provisions thereof).

EXHIBIT B

Opinion of

Xxxxxxx XxXxxxxxx LLP

Regulatory Counsel for the Company

1. The licenses, permits and authorizations set forth in Attachment A of the Officer’s Certificate delivered in connection with such opinion constitute all of the material licenses, permits and authorizations required by the Federal Communications Commission (“FCC”) and the State Regulatory Agencies (as defined below) for the provision of telecommunications services by the Company and the Subsidiaries as such counsel understands those services currently to be provided based solely on the Officer’s Certificate, where the failure to obtain or hold such license, permit or authorization would materially adversely affect the ability of the Company or the Subsidiaries to provide such services, and, to the knowledge of counsel, none of the Company or any Subsidiary has received any notice of proceedings relating to the revocation or modification of any such license, permit or authorization which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a material adverse affect on the Company or such Subsidiary, in connection with the provision of such services as counsel understands those services to be provided based solely on the Officer’s Certificate.

2. To the knowledge of such counsel, after reasonable inquiry with the FCC and relevant State Regulatory Agencies, neither the Company nor any of the Subsidiaries is subject to any pending or threatened proceeding, complaint or investigation before the FCC or any State Regulatory Agency based on any alleged violation by the Company or its Subsidiaries in connection with the provision of or failure to provide telecommunications services, of a character that would be required to be disclosed or incorporated by reference in the Registration Statement, the Preliminary Prospectus Supplement and the Final Prospectus Supplement, which is not adequately disclosed in the Registration Statement, the Preliminary Prospectus Supplement and the Final Prospectus Supplement.

3. The statements included in the Preliminary Prospectus Supplement and the Final Prospectus Supplement under the headings “Risk Factors—We are subject to significant regulation that could change in an adverse manner” and “—Potential regulation of Internet service providers in the United States could adversely affect our operations”, “Business—Regulation—Federal Regulation”, “—State Regulation”, “—Local Regulation” and “—Regulation of Voice over Internet Protocol (VoIP) —Federal and State” (collectively, the “Applicable Sections”), fairly summarize in all material respects the matters of law therein described.

4. No consent, approval, authorization, license, certificate, permit or order of the FCC or any State Regulatory Agency is required for the consummation of the transactions contemplated by the Purchase Agreement.

5. Neither the execution and delivery of the Purchase Agreement, nor the issue and sale of the Securities contemplated thereby will conflict with or result in a violation by the Company or the Subsidiaries of the Communications Act or, to such counsel’s knowledge, a

material violation of any order, license, certificate, permit, authorization, regulation, rule, or published decision of the FCC or any State Regulatory Agency applicable to the Company or any of the Subsidiaries, the conflict with or the violation of which would have a material adverse effect on the business of the Company or its Subsidiaries, taken as a whole, or result in the suspension, revocation, impairment, forfeiture, nonrenewal or termination of any FCC license or other authorization of the FCC.

Such counsel has not itself determined the accuracy or completeness of, or otherwise verified, the factual information furnished with respect to the Applicable Sections in the Registration Statement, the Disclosure Package and the Final Prospectus Supplement, including any amendments or supplements thereto as of the date hereof. Such counsel has generally reviewed and discussed with representatives of and counsel for the Underwriters and with certain officers and employees of, and counsel for, the Company the information furnished in the Applicable Sections. Although such counsel has not independently checked or verified and is neither passing upon nor assuming any responsibility for the factual accuracy, completeness or fairness of the statements contained in the Applicable Sections, nothing has become known to the attorneys who have been engaged in the review and discussion of the information furnished in the Preliminary Prospectus Supplement and the Final Prospectus Supplement in the course of such review and discussion which would cause counsel to believe that the statements contained in or incorporated by reference in the Registration Statement, the Preliminary Prospectus Supplement and the Final Prospectus Supplement, including any amendments or supplements thereto as of the date hereof, in the Applicable Sections, at the Effective Date, the Applicable Time, on the date of the Final Prospectus Supplement or on the Closing Date contained or contain an untrue statement of material fact or omitted or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Such counsel expresses no opinion as to the statements contained under any other heading of the Registration Statement, the Preliminary Prospectus Supplement or the Final Prospectus Supplement, including any amendments or supplements thereto as of the date hereof. Counsel expresses no belief with respect to the financial statements (and notes and schedules thereto) and other statistical, financial or accounting data therein included.

EXHIBIT C

Opinion of

Internal Counsel for the Company Covering Canadian Regulatory Issues

The statements in the Preliminary Prospectus and the Final Prospectus under the captions “Risk Factors—Canadian law currently does not permit us to offer services in Canada” and “Canadian Regulation” insofar as such statements describe or summarize matters of law or constitute legal conclusions, fairly describe or summarize all matters referred to therein.

EXHIBIT D

Opinion of
