(i) The Company is not, and after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Final Prospectus, will not be, an "investment company" required to be registered under the Investment Company Act of 1940, as amended, without taking account of any exemption arising out of the number of holders of the Company's securities. (j) No consent, approval, authorization, filing with or order of any court or governmental agency or body is required in connection with the transactions contemplated herein or in the Indenture, except such as will be obtained under the Act and the Trust Indenture Act in connection with the registration of the Securities, and such as may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Underwriters in the manner contemplated herein or in the Final Prospectus.

(n) The pro forma financial statements included in the Final Prospectus include assumptions that provide a reasonable basis for presenting the significant effects directly attributable to the transactions and events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma adjustments reflect the proper application of those adjustments to the historical financial statement amounts in the pro forma financial statements included in the Final Prospectus. The pro forma financial statements included in the Final Prospectus comply as to form in all material respects with the applicable accounting requirements of Regulation S-X under the Act and the pro forma adjustments have been properly applied to the historical amounts in the compilation of those statements.

Agreements. The Company agrees with the several Underwriters that: (a) The Company will use its best efforts to cause the Registration Statement, if not effective at the Execution Time, and any amendment thereof, to become effective. Prior to the termination of the offering of the Securities, the Company will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Final Prospectus) to the Basic Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement without the prior consent of the Representatives, which consent shall not be unreasonably withheld, conditioned or delayed. Subject to the foregoing sentence, if the Registration Statement has become or becomes effective pursuant to Rule 430A, or filing of the Final Prospectus is otherwise required under Rule 424(b), the Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. If necessary for the sale of the Securities, the Company will cause the Rule 462(b) Registration Statement, completed in compliance with the Act and the applicable rules and regulations thereunder, to be filed with the Commission pursuant to Rule 462(b) and will provide evidence satisfactory to the Representatives of such filing. The Company will 13 promptly advise the Representatives (1) when the Registration Statement, if not effective at the Execution Time, shall have become effective, (2) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (3) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (4) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (5) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (6) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof. Prior to the completion of the sale of the Securities by the Underwriters, the Company will not file any document under the Exchange Act that is incorporated by reference in the Registration Statement unless, prior to such proposed filing, the Company has furnished the Representatives with a copy of such document for their review and the Representatives have not reasonably objected to the filing of such document within a reasonable period of time. The Company will promptly advise the Representatives when any document filed under the Exchange Act that is incorporated by reference in the Registration Statement shall have been filed with the Commission. (b) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it should be necessary to amend the Registration Statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, the Company promptly will (1) notify the Representatives of such event, (2) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance and (3) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request. 14 (c) In accordance with the requirements of the Exchange Act and the Act applicable to the Company, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

The Company will pay the expenses of printing or other production of all documents relating to the offering. (e) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the National Association of Securities Dealers, Inc., in connection with its review of the offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company shall use its best efforts to prevent the issuance of any order suspending the qualification or exemption of the Securities under any state securities or Blue Sky laws, and, if at any time any state securities commission or any other regulatory authority shall issue an order suspending the qualification or exemption of the Securities under any state securities or Blue Sky laws, the Company shall use every reasonable effort to obtain the withdrawal or lifting of such order at the earliest possible time. (f) The Company will not for a period of 180 days following the Execution Time, without the prior written consent of Salomon Smith Barney Inc., offer, sell or contract to sell, grant any other option to purchase or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or 15 otherwise) by the Company or any Affiliate of the Company or any person in privity with the Company or any Affiliate of the Company), directly or indirectly, any debt securities issued or guaranteed by the Company (other than the Securities) except the Company may offer, sell, contract to sell, pledge, or otherwise dispose of convertible subordinated notes to Bell Atlantic Investments, Inc. ("Bell Atlantic") pursuant to a securities purchase agreement dated October 7, 1999 between the Company and Bell Atlantic. (g) The Company will cooperate with the Representatives and use its best efforts to permit the Securities to be eligible for clearance and settlement through The Depository Trust Company (in the case of the U.S. Securities) or Euroclear/Cedel (in the case of the International Securities), as the case may be. (h) The Company will not take, directly or indirectly, any action designed to or which has constituted or which might reasonably be expected to cause or result, under the Exchange Act or otherwise, in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities. (i) The Company will not, for so long as the Securities are outstanding, be or become, or be or become owned by, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act, and will not be or become, or be or become owned by, a closed-end investment company required to be registered, but not registered thereunder. (j) The Company will apply the net proceeds from the sale of the Securities as set forth in the Final Prospectus under the heading "Use of Proceeds."

(l) The Company agrees to do and perform all things required to be done and performed by it under this Agreement that are within its control on or prior to or after the Closing Date, as applicable, and to use its best efforts to satisfy all conditions precedent on its part to the delivery of the Securities. (m) The Company confirms that it has caused to be made an application for the Securities to be listed on the Exchange. In connection with such application, the Company agrees to furnish from time to time any and all documents, instruments, information and undertakings and publish all advertisements or other material that may be necessary in order to effect and maintain such listing and to use its reasonable best efforts to maintain such listing so long as any of the Securities are outstanding (as defined in the Indenture); provided that if at any time the Company shall determine that it can no longer reasonably comply with the requirements for listing of the Securities on the Exchange and if maintenance of such listing becomes onerous, it will use its reasonable best efforts to obtain and thereafter to maintain a listing of Securities on such other stock exchange in a financial center as you may reasonably request and as the Trustee may approve. 6.

iii. this Agreement has been duly authorized, executed and delivered by the Company; iv. the Indenture has been duly qualified under the Trust Indenture Act and has been duly authorized, executed and delivered by the Company, and, assuming due authorization, execution and delivery thereof by the Trustee, constitutes a legal, valid and binding instrument enforceable against the Company in accordance with its terms (subject to applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and to general principles of equity, regardless of whether enforceability is considered in a proceeding in equity or at law); the Securities have been duly and validly authorized by the Company, and, when duly executed, issued and authenticated in accordance with the provisions of the Indenture and delivered to and paid for in full by the Underwriters under this Agreement, will constitute legal, valid and binding obligations of the Company entitled to the benefits of the Indenture (subject to applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance or other laws affecting creditors' rights generally from time to time in effect and to general principles of equity, regardless or whether enforceability is considered in a proceeding in equity or at law); and the statements set forth under the heading "Description of the Notes", insofar as such statements purport to summarize certain provisions of the Securities and the Indenture, provide a fair summary of such provisions; v. to the extent that they constitute a summary of U.S. federal law and regulations, the statements in the Final Prospectus under the heading "Certain United States Federal Income Tax Considerations" fairly summarize the matters therein described in all material respects;

In addition, such counsel shall state that it has participated in conferences with officers and other representatives of the Company, representatives of the independent accountants of the Company, the Underwriters and counsel for the Underwriters at which the contents of the Registration Statement and the Final Prospectus and related matters were discussed and, although such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Final Prospectus (or any amendments or supplements thereto) and has made no independent investigation or verification thereof, and such counsel has not participated in the preparation of the Incorporated Documents, on the basis of the foregoing, no facts have come to the attention of such counsel that have led such counsel to believe that the Registration Statement, at the Effective Time, and the Final Prospectus, at the Execution Time and on the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other than the financial statements, schedules and other financial and statistical information 22 which are contained or incorporated by reference therein or omitted therefrom and the Form T-1, as to which such counsel need express no opinion). In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of New York, the Federal laws of the United States or the General Corporation Law of the State of Delaware, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are reasonably satisfactory to counsel for the Underwriters; and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

In rendering such opinion, such counsel may state that they express no opinion as to the laws of any jurisdiction other than Germany or the United Kingdom or the regulations of the European Union. 23 (e) The Representatives shall have received from Skadden, Arps, Slate, Meagher & Flom LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Registration Statement, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(g) At the Execution Time and at the Closing Date, the Company shall have requested and caused Ernst & Young LLP to furnish to the Representatives letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Act and the Exchange Act and the applicable rules and regulations 24 thereunder, that they have performed a review of the unaudited interim financial information of the Company for the nine month period ended September 30, 1999 and as at September 30, 1999 and stating in effect that: i. in their opinion the audited financial statements and financial statement schedules included or incorporated in the Registration Statement and the Final Prospectus and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published rules and regulations thereunder; 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 standards established under Statement on Auditing Standards No. 71, of the unaudited interim financial information for the nine month period ended September 30, 1999, and as at September 30, 1999; 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 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, 1998, nothing came to their attention which caused them to believe that: (1) any unaudited financial statements included or incorporated in the Registration Statement and the Final Prospectus do not comply in form in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect to financial statements included or incorporated in quarterly reports on Form 10-Q under the Exchange Act; or that 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 in the Registration Statement and the Final Prospectus; (2) with respect to the period subsequent to September 30, 1999, there were any changes, at a specified date not more than three days prior to the date of the letter, in the capital stock, increase in long-term debt of the Company and its subsidiaries or stockholders' equity of the Company as compared with the amounts shown on the September 30, 1999 consolidated balance sheet included in the Final Prospectus, or for the period from October 1, 1999 to such specified date there were any decreases, as compared with the corresponding 25 period in the preceding year in revenues of the Company and its subsidiaries, except in all instances for changes or decreases 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 (3) the information included under the headings "Selected Consolidated Financial Data" and "Management-Executive Compensation" is not in conformity with the disclosure requirements of Regulation S-K;

and iv. on the basis of a reading of the unaudited pro forma financial statements included or incorporated by reference in the Registration Statement and the Final Prospectus (the "pro forma financial statements"); carrying out certain specified procedures; inquiries of certain officials of the Company and AboveNet Communications, Inc. who have responsibility for financial and accounting matters; and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the pro forma financial statements, nothing came to their attention which caused them to believe that the pro forma financial statements do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such statements. (h) [Intentionally Omitted] 26 (i) At the Execution Time and at the Closing Date, Deloitte & Touche LLP shall have furnished to the Representatives letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Act and the applicable rules and regulations thereunder, and stating in effect that: i. in their opinion the audited financial statements and financial statement schedules included in the Registration Statement and the Final Prospectus and reported on by them comply in form in all material respects with the applicable accounting requirements of the Act and the related published rules and regulations; and ii. 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 and the Final Prospectus agrees with the accounting records of the Company and its subsidiaries, excluding any questions of legal interpretation.

Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. (q) The documents required to be delivered by this Section 6 will be delivered at the office of Paul, Weiss, Rifkind, Wharton & Garrison, counsel for the Company, at 1285 Avenue of the Americas, New York, New York 10019, on the Closing Date. (r) Prior to the Closing Date the Company shall have applied to list the Securities on the Luxembourg Stock Exchange. 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 other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through 29 Salomon Smith Barney Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of one counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 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 Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged 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 Final Prospectus or the Final Prospectus, 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, in the light of the circumstances under which they were made, 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 (i) 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 and (ii) with respect to any untrue statement or alleged untrue statement of, or omission or alleged omission to state, a material fact made in any Preliminary Final Prospectus, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of any Underwriter (or any of the directors, officers, employees and agents of such Underwriter or any controlling person of such Underwriter) from whom the person asserting any such loss, claim, damage or liability purchased the Securities concerned, to the extent that any such loss, claim, damage or liability of such Underwriter occurs under the circumstances where it shall have been determined by a court of competent jurisdiction (or appropriate arbitral proceeding) by final and nonappealable judgment that (w) the Company had previously furnished copies of the Final Prospectus to the Underwriters, (x) delivery of the Final Prospectus was required by the Act or under this Agreement to be made to such person, (y) the untrue statement or omission of a material fact contained in the Preliminary Final Prospectus was corrected in the Final Prospectus and (z) there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the Final Prospectus. This indemnity agreement will be in addition to any liability which the Company may otherwise have. 30 (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 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 the statements set forth in the last paragraph of the cover page regarding delivery of the Securities, the first paragraph on page S-3 related to stabilization, syndicate covering transactions and penalty bids and, under the heading "Underwriting" or "Plan of Distribution", (i) the list of Underwriters and their respective participation in the sale of the Securities, (ii) the sentences related to concessions and reallowances and (iii) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Final 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 Final 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 as determined by a court of competent jurisdiction; 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 assume the defense of such action and 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 assume the defense of such action or 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 31 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, which has not been waived; (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 been reasonably advised by such counsel that there are 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 assumed the defense of the action or 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. In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties. 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. (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 32 the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions or alleged statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the 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 or alleged 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 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 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 Act or the Exchange Act and 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 remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal 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 principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to (i) make arrangements for the purchase of the Securities which such defaulting Underwriter or 33 Underwriters agreed but failed to purchase by other persons satisfactory to the Company and the non-defaulting Underwriters, and/or (ii) purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not make such arrangements and/or purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. 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 five 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 or 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 the Company's Common Stock shall have been suspended by the Commission or the NASDAQ National Market or trading in securities generally on the New York Stock Exchange or the NASDAQ National Market shall have been suspended or limited or minimum prices shall have been established on such exchange or the NASDAQ National Market; (ii) a banking moratorium shall have been declared either by Federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Prospectus (exclusive of any amendment or 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 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. Notices.
