The information included in any such prospectus supplement that was omitted from such registration statements at the time they became effective but that is deemed to be part of such registration statements at the time they became effective (a) pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information" or (b) pursuant to paragraph (d) of Rule 434 is referred to as "Rule 434 Information." The Form of Prospectus Supplement used before such registration statements became effective, and any prospectus supplement that omitted, as applicable, the Rule 430A Information or the Rule 434 Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "Preliminary Prospectus." Such registration statements, including the exhibits thereto and schedules thereto, at the time they became effective and including the Rule 430A Information and the Rule 434 Information, as applicable, are herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The base prospectus included in the Registration Statement relating to all offerings of securities under the Registration Statement, as supplemented by the final Form of Prospectus Supplement is herein called the "Prospectus," except that, if such base prospectus is amended or supplemented on or prior to the date on which the Prospectus Supplement is first filed pursuant to Rule 424, the term "Prospectus" shall refer to the base prospectus as so amended or supplemented and as supplemented by the Prospectus Supplement, including the documents filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the "1934 Act"). For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, each Selling Shareholder, severally and not jointly, hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional 812,337 shares of Common Stock as set forth in Schedule B, at the price per share set forth in Schedule C, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised not more than two times in whole or in part only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by Merrill Lynch to the Company and the Selling Shareholders setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery for the Option Securities (a "Date of Delivery") shall be determined by the Merrill Lynch, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, on the basis of the representations and warranties of the Company and each Selling Shareholder contained herein and subject to the terms and conditions herein set forth, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as Merrill Lynch in its discretion shall make to eliminate any sales or purchases of fractional shares. (c) Payment. Payment of the purchase price for the Initial Securities shall be made at the offices of Cahill Gordon & Reindel, 80 Pine Street, New York, New York 10005 or at such other place as shall be agreed upon by Merrill Lynch and the Company, at 9:00 A.M.

(Eastern time) on the date hereof) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by Merrill Lynch and the Company (such time and date of payment and delivery being herein called "Closing Time"). 21 -17- In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by Merrill Lynch and the Company, on each Date of Delivery as specified in the notice from Merrill Lynch to the Company. Payment shall be made to the Selling Shareholders by wire transfer of immediately available funds to bank accounts designated by the Custodian pursuant to each Selling Shareholder's Custody Agreement. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase.

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or 32 -28- omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(c) below) any such settlement is effected with the written consent of the Company; and (iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment or supplement thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); provided, further that the Company shall not be liable for any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or made in reliance upon and in conformity with Selling Shareholder Information (as defined); provided, further that neither the Company nor any Selling Shareholder will be liable to an Underwriter with respect to any preliminary prospectus to the extent that any such loss, liability, claim, damage or expense resulted from the fact that such Underwriter, in contravention of a requirement of this Agreement or applicable law, sold Securities to a person to whom such Underwriter failed to send or give, at or prior to the Closing Date, a copy of the Prospectus, as then amended or supplemented if: (i) the Company has previously furnished copies thereof (sufficiently in advance of the Closing Date to allow for distribution by the Closing Date) to the Underwriters and the loss, liability, claim, damage or expense of such Underwriter resulted from an untrue statement or omission of a material fact contained in or omitted from the preliminary prospectus which was corrected in the Prospectus as, if applicable, amended or supplemented prior to the Closing Date and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person and (ii) such failure to give or send such Prospectus by the 33 -29- Closing Date to the party or parties asserting such loss, liability, claim, damage or expense would have constituted the sole defense to the claim asserted by such person; provided, further, that each Selling Shareholder shall be liable only with reference to information relating to such Selling Shareholder furnished to the Company in writing by or on behalf of such Selling Shareholder expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement thereto (it being understood that such information is limited to the extent and as described in Section 1(b)(i) hereof) (the "Selling Shareholder Information"); provided, further, that each Selling Shareholder's aggregate liability under this Section 6(a) shall be limited to an amount equal to the gross proceeds (after deducting the underwriting discount, but before deducting expenses) received by such Selling Shareholder from the sale of the Securities pursuant to the Purchase Agreement. (b) Indemnification of Company, Directors and Officers and Selling Shareholders. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, each Selling Shareholder and each person, if any, who controls any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment or supplement thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment or supplement thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto). (c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a 34 -30- result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. 35 -31- (e) Other Agreements with Respect to Indemnification. The provisions of this Section shall not affect any agreement among the Company and the Selling Shareholders with respect to indemnification. SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportions that (a) the Underwriters are responsible for that portion represented by the percentage that the underwriting discount appearing on the cover page of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bears to the offering price appearing thereon and (b) the Company and the Selling Shareholders are severally responsible for the balance on the same basis as each of them would have been obligated to provide indemnification pursuant to Section 6 or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Selling Shareholders on the second hand and of the Underwriters on the third hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling Shareholders and the Underwriters shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholders or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of 36 -32- losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7, (i) no Selling Shareholder shall be required to contribute any amount in excess of the amount of the total net proceeds received by such Selling Shareholder from the Securities purchased from such Selling Shareholder and (ii) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls a Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any the Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any Venture or the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made 37 -33- by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company or the Selling Shareholders, and shall survive delivery of the Securities to the Underwriters. SECTION 9. Termination of Agreement. (a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company and the Selling Shareholders, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission, EASDAQ or the Nasdaq National Market, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representatives shall have the 38 -34- 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 Defaulted Securities 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: (a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or (b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Selling Shareholders to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Selling Shareholders to sell the relevant Option Securities, as the case may be, either (i) the Representatives or (ii) the Company and any Selling Shareholder shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section 10. SECTION 11. Default by One or More of the Selling Shareholders. (a) If one or more of the Selling Shareholders selling an aggregate of at least $15,000,000 of Securities shall fail at Closing Time or at a Date of Delivery to sell and 39 -35- deliver the number of Securities which such Selling Shareholder or Selling Shareholders are obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Securities to be sold by them hereunder to the total number to be sold by all Selling Shareholders as set forth in Schedule B hereto, then the Underwriters may, at option of the Representatives, by notice from the Representatives to the Company and the non-defaulting Selling Shareholders, either (a) terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect or (b) elect to purchase the Securities which the non-defaulting Selling Shareholders have agreed to sell hereunder. No action taken pursuant to this Section 11 shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default. In the event of a default by any Selling Shareholder as referred to in this Section 11, each of the Representatives, the Company and the non-defaulting Selling Shareholders shall have the right to postpone Closing Time or the Date of Delivery for a period not exceeding seven days in order to effect any required change in the Registration Statement or Prospectus or in any other documents or arrangements. SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and the Selling Shareholders and their respective successors and the controlling persons and officers and directors referred to in 40 -36- Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and the Selling Shareholders and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.

A-1-1 48 of the agreements set forth in Annex A attached hereto, (B) any existing applicable law, rule or regulation which, in each instance in our experience, are normally applicable to corporations such as the Company or transactions of this type, other than the securities or blue sky laws of the various states, as to which, in each case, we express no opinion or (C) any judgment, order or decree of any Federal or New York court, governmental agency or body or arbitrator known by us to be applicable to the Company (except for such conflicts, defaults or liens, charges or encumbrances, with respect to clause (2) above, that would not reasonably be expected to result in a Material Adverse Effect); 7.

The authorized and issued and outstanding capital stock of the Company was, at December 31, 1998, as set forth in the Prospectus in the column entitled "Actual" under the caption "Capitalization"; all of the issued and outstanding shares of capital stock of the Company have been duly authorized and validly issued and are fully paid and nonassessable; and none of the outstanding shares of capital stock of the Company was issued in violation of the preemptive rights of any securityholder of the Company; 3.

To the best of such counsel's knowledge, the execution and delivery by the Company of the Purchase Agreements and the consummation of the transactions contemplated in the Purchase Agreements and in the Registration Statement, and compliance by the Company with the terms thereof will not result in any (1) violation of the Certificate of Incorporation or By-Laws of the Company, and (2) will not conflict with, or constitute default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to (A) any of the agreements set forth in Annex A attached hereto, (B) any existing applicable law, rule or regulation which, in each instance in such counsel's experience, are normally applicable to corporations such as the Company or transactions of this type, other than the securities or blue sky laws of the various states, as to which, in each case, need not express any opinion or (C) any judgment, order or decree of any Federal or New York court, governmental agency or body or arbitrator known by me to be applicable to the Company (except for such conflicts, defaults or liens, charges or encumbrances, with respect to clause (2) above, that would not reasonably be expected to result in a Material Adverse Effect); 5. To the best of such counsel's knowledge, (a) there is no pending action, suit, proceeding, inquiry or investigation before or brought by any U.S. court or governmental agency or body, with which the Company or any of its subsidiaries has been served, (I) to which the Company or any of its subsidiaries is a party or (II) to which the property of the Company or any of its subsidiaries is subject, or (b) any such action, suit, proceeding, inquiry or investigation threatened, in each case which might reasonably be expected to result in a Material Adverse Effect; and 6.

A-2-2 52 In addition, such counsel shall state that (i) in such counsel's opinion, the Registration Statement and the Prospectus (other than the financial statements and other financial data contained therein or omitted therefrom, as to which such counsel need not comment) appear on their face to be appropriate responsively in all material respects to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder; (ii) no facts came to such counsel's attention which gave such counsel reason to believe that (a) the Registration Statement (other than the financial statements and other financial data contained therein or omitted therefrom, as to which such counsel need not comment), at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (b) the Prospectus (other than the financial statements and other financial data contained therein or omitted therefrom, as to which we have not been requested to comment), as of their date or the Closing Date, contained or contain an untrue statement of a 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; and (iii) such counsel does not know of any contract or other document of a character required to be filed as an exhibit to the Registration Statement that is not so filed. A-2-3 53 Exhibit A-3 FORM OF OPINION OF COUDERT BROTHERS TO BE DELIVERED PURSUANT TO SECTION 5(b) 1. The statements in the Prospectus relating to the Offering under the captions "RISK FACTORS Delays in regulatory liberalization in EU member states could adversity affect our service offerings in these countries" and "BUSINESS - Licenses and Regulatory Issues," insofar as they purport to constitute a summary of the matters expressly referred to therein, fairly describe such matters in all material respects. 2. Hermes Europe Railtel B.V. ("Hermes") and Esprit Telecom Group plc ("Esprit"), or their respective subsidiaries, have obtained all necessary licences, authorizations, consents and approvals (collectively the "Authorizations") of and from, and has made all necessary filings with and notices to all Danish, Swedish, Spanish, Luxembourgian, United Kingdom, Belgian, French, German, Italian, Dutch, Swiss, and United States governmental authorities, regulatory agencies, courts and tribunals necessary to render lawful the conduct of its business as an operator of telecommunication facilities and provider of telecommunication services within the said countries, as such is described in the Registration Statement dated April 19, 1999 relating to the Offering (with respect to each of Hermes and Esprit, the "Business"). 3. So far as such counsel is aware, having made due inquiry of the Company (a) Neither Hermes nor Esprit has received any notice of proceedings relating to the revocation or modification of any such Authorizations, and (b) Each of Hermes and Esprit is conducting its business in accordance with the Authorizations and is not in violation of, or in default under, any condition or other provision of the Authorizations or any national or regional laws, regulation, rule, order or judgment with respect to the Authorizations or the conduct of the Business. 4. Each of the Russian companies listed on Schedule 1 (the "Russian Companies") has been duly organized A-3-1 54 and is validly existing as a legal entity registered under the laws of the Russian Federation and has the corporate power and authority to carry on its business and to own, lease and operate its properties as disclosed in the Prospectus. 5. All of the outstanding shares of capital stock or ownership interests, as applicable, of each of the Russian Companies have been duly authorized and validly issued and the issuance of such shares was properly registered with the appropriate authorities competent therefor, and, to the best of such counsel's knowledge, to the extent owned, directly or indirectly, by GTS, are owned free and clear of any security interest, claim, lien, encumbrance or adverse interest of any nature. GTS owns, directly or indirectly, that percentage of the issued and outstanding shares of capital stock or ownership interests of the Russian Companies set forth on Schedule 1 hereto as being owned by GTS. 6. Except as disclosed in the Prospectus, under current legislation of the Russian Federation, as applicable, (i) subject to the qualifications set forth in paragraph (e) hereof, dividends and other distributions declared and payable on the issued and outstanding shares of the Russian Companies may be paid to the foreign shareholders in U.S. Dollars and may be transferred by such foreign shareholders out of the Russian Federation, as the case may be; (ii) all such dividends are, and other distributions may be, subject to withholding taxes unless an international treaty provides otherwise and the procedures set forth in applicable Russian legislation enabling the foreign shareholders to avail themselves of such treaty benefits are followed; and (iii) such dividends and distributions are otherwise free and clear of any other tax or deduction in the Russian Federation, provided that all profits and other taxes have been paid by the relevant Russian Company prior to the payment of such dividends and distributions. 7. Except as disclosed in the Prospectus, each Russian Company has such telecommunications permits, licenses and authorizations of governmental or regulatory authorities, including, without limitation, licenses issued by the State Committee of the Russian Federation on Communications and Information (formerly the Ministry of Communications) (the "Telecommunications Licenses"), permissions issued by the State Service for Communications Oversight (also referred to as Gossviaznadzor), and/or radio-frequency allocations issued by the State Commission for Radio Frequencies (all of the foregoing, without A-3-2 55 limitation, being the "Telecommunications Permits"), which are necessary to own, lease, and operate its respective properties and to conduct its business as disclosed in the Prospectus. Such Telecommunications Permits contain no restriction that is likely to have a material adverse effect on the business, condition (financial or other), properties, net worth, results of operations or prospects (a "Material Adverse Effect") of such Russian Company. Except as disclosed in the Prospectus, to the best of such counsel's knowledge, each of the Russian Companies has fulfilled and performed all of its material obligations with respect to such Telecommunications Permits and no event has occurred which creates, or after notice or lapse of time or both would create, a material likelihood that such Telecommunications Permits would be revoked or terminated. 8.
