In furtherance and not in limitation of the foregoing, each of Buyer and the Sellers agrees (i) as promptly as practicable after the date hereof, but in any event within fifteen (15) Business Days of the date hereof, to make an appropriate filing with each of CADE and ANATEL with respect to the transactions contemplated by this Agreement, (ii) as promptly as practicable after the date hereof, but in any event within thirty (30) days of the date hereof, to make an appropriate filing with CVM with respect to the transactions contemplated by this Agreement to obtain the approval of the public offer referred to in Section 5.09(a) hereof, (iii) to comply with all of the requirements of the applicable Boards of Trade including, without limitation, the filing of amendments to the respective articles of association of each of the Companies in order to assign and transfer the Shares, (iv) to make such other filings as are required under Laws, rules and regulations governing antitrust or merger control matters with respect to the transactions contemplated hereby as promptly as practicable after the date hereof, (v) to take any act, make any undertaking or receive any clearance or approval required by CADE, ANATEL, CVM, any other Governmental Entity or under applicable Law and (vi) not to take any action that would reasonably be expected to materially delay or prevent the consummation of the transactions contemplated hereby. 12 (b) Each of Buyer and the Sellers will, and will cause its respective Affiliates (provided that the Sellers will use their commercially reasonable efforts to cause Embratel and its Subsidiaries) to (i) respond as promptly as practicable to any inquiries or requests received from any Governmental Entity for additional information or documentation, and (ii) not enter into any agreement with any Governmental Entity not to consummate, or delay the consummation of the transactions contemplated by this Agreement, except with the prior consent of the other party (which consent shall not be unreasonably withheld or delayed). (c) [Intentionally Omitted]. (d) From the date hereof to Closing, subject to compliance with all applicable Laws, and to the extent permissible under Section 2.04 hereof, Parent and the Sellers shall use commercially reasonable efforts to cause Embratel and its Subsidiaries, officers, directors, employees, auditors and agents to afford the officers, employees and agents of Buyer reasonable access at reasonable times to its officers, employees, agents, properties, offices and other facilities and to all books and records; provided, however, that Buyer shall have a reasonable need for such access and shall not interfere with the operation of business of Embratel or its Subsidiaries. (e) Subject to Section 2.04 hereof and to compliance with all applicable Laws, each of Buyer and the Sellers shall (i) promptly notify the other party of any written communication to that party or its Affiliates (other than Embratel and its Subsidiaries) from any Governmental Entity and permit the other party to review in advance any proposed written communication to any of the foregoing; (ii) not agree to participate in any substantive meeting or discussion with any Governmental Entity in respect of any filings, investigation or inquiry concerning this Agreement or the transactions contemplated hereby unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate at any such meeting; and (iii) furnish the other party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between it and its representatives on the one hand, and any Governmental Entities or members of their respective staffs on the other hand, with respect to this Agreement and the transactions contemplated hereby (except that the Sellers shall be under no obligation of any kind to provide Buyer with any documents, material or other information relating to the valuation of Embratel or to alternatives to this Agreement and the transactions contemplated hereby). (f) As an added inducement to Parent and the Sellers to enter into this Agreement with Buyer, the parties hereto intend and have agreed that Buyer shall make certain payments to the Sellers in the event that the regulatory approvals required in order to consummate the transactions contemplated hereby are delayed or not obtained or injunctions in respect of the granting thereof are issued. Consistent therewith, (i) on the first Business Day following the date hereof, Buyer shall pay an amount in cash equal to U.S.$20,000,000 (TWENTY MILLION DOLLARS) to an account of Sellers designated by the Sellers, by wire transfer of immediately available funds, and (ii) if the Closing shall not already have occurred, on (A) the date that is ninety (90) days after the date of the entry of the Sale Order or (B) July 9, 2004 if the Effective Date shall 13 have occurred prior to the Bankruptcy Court having entered the Sale Order, Buyer shall pay an additional amount in cash equal to U.S.$10,000,000 (TEN MILLION DOLLARS) to an account of Sellers designated by the Sellers, by wire transfer of immediately available funds; provided that, if on the applicable date specified in clause (ii)(A) or (ii)(B) above the conditions to Closing set forth in Section 6.01(c) and Section 6.02 have not been satisfied or waived by the parties hereto, then such payment shall be delayed until the first Business Day thereafter on which such conditions set forth in Section 6.01(c) and Section 6.02 shall have been satisfied or waived. The payment referred to in clause (ii) above shall be made by Buyer regardless of whether the various other conditions precedent to the consummation of the Share Purchase have then been satisfied or waived (including, without limitation, the receipt of all requisite regulatory and other legal approvals). The date on which the payment referred to in clause (ii) above is due shall be referred to herein as the "Payment Due Date" and the date on which such payment is made shall be referred to herein as the "Payment Date." In the event that this Agreement is validly terminated by (x) Buyer pursuant to Section 7.01(b) (but only if the order, decree, ruling or other action issued or taken by such Governmental Entity is of a non-regulatory nature (which, for purposes hereof, shall mean that such order, decree, ruling or other action does not arise out of, relate to or concern antitrust, competitition or telecommunications matters)) or Sections 7.01(d), (i) or (j) hereof, or (y) Parent or the Sellers pursuant to Sections 7.01(b) (but only if the order, decree, ruling or other action issued or taken by such Governmental Entity is of a non-regulatory nature (which, for purposes hereof, shall mean that such order, decree, ruling or other action does not arise out of, relate to or concern antitrust, competitition or telecommunications matters)) or Sections 7.01(e), (f) or (g), then the Sellers shall pay to Buyer promptly (but in any event within ten (10) Business Days) following such termination all amounts previously paid by Buyer to the Sellers pursuant to this Section 5.01(f) as of the date of such termination. In addition, in the event that this Agreement is validly terminated by Buyer pursuant to Section 7.01(k) hereof on or before the Payment Due Date, then the Sellers shall pay to Buyer promptly (but in any event within ten (10) Business Days) following such termination all amounts previously paid by Buyer to the Sellers pursuant to this Section 5.01(f) as of the date of such termination. Notwithstanding anything contained herein to the contrary, until all requisite regulatory approvals are obtained and the Closing shall have occurred, the Sellers shall continue to exercise full and exclusive control of the Companies and New Startel. If the Closing shall not have occurred by July 8, 2005 (the "Outside Date") and the conditions to Closing set forth in Section 6.01(c) and Section 6.02 have been satisfied or waived by the parties hereto, Buyer shall unconditionally and irrevocably pay an additional amount in cash equal to U.S.$10,000,000 (TEN MILLION DOLLARS) as well as all amounts theretofore due and payable and not yet paid by Buyer under this Section 5.01(f) (such payment, the "Termination Amount") to an account of the Sellers designated by the Sellers, by wire transfer of immediately available funds; provided, however, that if at any time, there shall be a final and non-appealable order of or other final determination by ANATEL or CADE permanently restraining, denying, enjoining or otherwise prohibiting the transactions contemplated by this Agreement or other action is taken or not taken by ANATEL or CADE which has such effect or this Agreement is terminated pursuant to Section 7.01(b) hereof where 14 the relevant order, decree, ruling or other action is of a regulatory nature (as referred to above) (a "Termination Event"), then Buyer shall promptly thereafter unconditionally and irrevocably pay the Termination Amount to an account of the Sellers designated by the Sellers, by wire transfer of immediately available funds; provided further, however, that if a Termination Event occurs prior to the Payment Date, then the Termination Amount shall be an amount in cash equal to U.S.$20,000,000 (TWENTY MILLION DOLLARS). Section 5.02. Certain Filings. Buyer and the Sellers shall cooperate with one another and use their commercially reasonable efforts (i) in determining whether any action by or in respect of, or filing with, any Governmental Entity is required, or any actions, consents, approvals or waivers are required to be obtained from parties to any material contracts, in connection with the consummation of the transactions contemplated by this Agreement and (ii) in taking such actions or making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such actions, consents, approvals or waivers. Section 5.03. Conduct of the Sellers. (a) During the period from the date of this Agreement to the Closing Date, except as may be required by applicable Law, the Sellers shall not, and shall cause the Companies and New Startel not to, without the consent of Buyer, except for and as provided under the Usufruct with respect to the shares of Common Stock held by New Startel, (i) sell, transfer (including by operation of law), give, pledge, encumber, assign or otherwise dispose of, or enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, gift, pledge, encumbrance, assignment or other disposition of, the Shares or any shares of Common Stock, other than for those Encumbrances which will be released prior to the Closing; provided, however, that the vesting of assets in the reorganized Sellers in accordance with the Chapter 11 Plan upon emergence from chapter 11 of the Bankruptcy Code shall not constitute a transfer or other disposition of the Shares in contravention of this subsection, (ii) deposit the Shares or any shares of Common Stock into a voting trust or grant any proxies or enter into a voting agreement, power of attorney or voting trust with respect to the Shares or any shares of Common Stock, other than any such actions in connection with the voting of the shares of Common Stock at any meeting of the shareholders of Embratel or by written consent of the shareholders, in each case, occurring prior to the Closing Date, (iii) adopt or propose any change in their respective organizational documents other than in connection with the Chapter 11 Plan, (iv) merge or consolidate with any other Person or acquire assets, equity or debt of any Person, or make loans or extensions of credit to any Person, (v) take any action that would have the effect of preventing or materially delaying the Sellers from performing any of their respective obligations under this Agreement, or (vi) make, declare or pay any dividend or distribution on, or directly or indirectly redeem, purchase or otherwise acquire, any Shares or any securities or obligations convertible into or exchangeable for any Shares, other than as permitted by Section 5.15. 15 (b) During the period from the date of this Agreement to the Closing Date, except as otherwise expressly provided for herein or required by applicable Law, the Sellers shall use their commercially reasonable efforts to cause each of Embratel and its Subsidiaries to conduct its business and operations in the ordinary course consistent with past practice, to maintain and preserve its business organization and its material rights and franchises, and to retain the services of its officers and key employees and maintain relationships with material customers, suppliers, lessees, licensees and other third parties to the end that its goodwill and ongoing business shall not be impaired in any material respect. Without limiting the generality of the foregoing, during the period from the date of this Agreement to the Closing Date, except as set forth in Section 5.03 of the Seller Disclosure Schedule and to the extent permissible under Section 2.04 hereof, the Sellers shall use their commercially reasonable efforts to cause Embratel and its Subsidiaries not to, without the prior written consent of Buyer: (i) do or effect any of the following actions with respect to any securities of Embratel: (A) adjust, split, combine, recapitalize or reclassify its capital stock, (B) make, declare or pay any dividend or distribution on, or directly or indirectly redeem, purchase or otherwise acquire, any shares of its capital stock or any securities or obligations convertible into or exchangeable for any shares of its capital stock other than for dividends paid by Embratel in the ordinary course of business on the shares of preferred stock, without par value, of Embratel, and other than pursuant to the terms of such capital stock as set forth in Embratel's By-Laws, (C) grant any Person any right or option to acquire any shares of its capital stock other than grants to directors, officers and employees pursuant to and in accordance with the terms of Embratel's existing stock option plan(s) as of the date hereof and in amounts consistent with past practice, (D) issue, deliver or sell or agree to issue, deliver or sell any additional shares of its capital stock or any securities, instruments or obligations convertible into or exchangeable or exercisable for any shares of its capital stock or such securities (except (i) pursuant to the exercise of outstanding options and options issued after the date hereof in accordance with clause (C) of this paragraph, (ii) for grants of stock to directors, officers and employees pursuant to and accordance with Embratel's existing stock grant plan(s) (if any) as of the date hereof and in amounts consistent with past practice and (iii) for issuances of shares of capital stock or securities, instruments or obligations convertible into or exchangeable or exercisable for shares of capital stock or securities, for cash at fair market value in an amount not to exceed $100,000,000 in the aggregate) or (E) enter into any agreement, understanding or arrangement with respect to the sale or voting of its capital stock; (ii) sell, transfer, lease, pledge, mortgage, encumber or otherwise dispose of any amount of its property or assets that is material to Embratel and its Subsidiaries, taken as a whole, other than in the ordinary course of business consistent with past practice; (iii) make or propose any changes in its By-Laws or similar organizational document; 16 (iv) merge or consolidate with any other Person or acquire assets or capital stock of any other Person which are material to Embratel and its Subsidiaries, taken as a whole; or (v) authorize any of, or commit, propose or agree to take any of, the foregoing actions.

Section 5.04. Public Announcements. Buyer, Parent and the Sellers will consult with each other before issuing any press release or making any public statement with respect to this Agreement or the transactions contemplated hereby and, except as may be required by applicable Law or any listing agreement with any national securities exchange, will not issue any such press release or make any such public statement prior to such consultation.

Section 5.06. Refinancing of Certain Indebtedness.

(b) From and after the Closing Date, Buyer shall use its commercially reasonable efforts to cause Embratel to maintain in effect, for the six-year period commencing immediately after the Closing Date, Embratel's current directors' and officers' liability insurance covering acts or omissions occurring prior to the Closing Date with respect to those persons who are currently covered by Embratel's directors' and officers' liability insurance policy on terms with respect to such coverage and amount no less favorable to Embratel's directors and officers currently covered by such insurance than those of such policy in effect on the date hereof or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that Buyer shall not be required to use its commercially reasonable efforts to cause Embratel to pay an annual premium for such directors' and officers' liability insurance in excess of 200% of the annual premium currently paid by Embratel for such insurance, but in such case shall cause Embratel to purchase as much of such coverage as possible for that amount; provided, further, however, that, if Embratel's current directors' and officers' liability insurance expires, is terminated or is canceled, Buyer shall use its commercially reasonable efforts to cause Embratel to obtain directors' and officers' liability insurance covering such acts or omissions with respect to each such person on terms with respect to such coverage and amount no less favorable to Embratel's directors and officers currently covered by such insurance than those of such policy in effect immediately prior to the date of such expiration, termination or cancellation, subject to the immediately preceding proviso.

In the event that the Sale Order entered by the Bankruptcy Court does not provide such an exemption and Transfer Taxes are required to be paid, or in the event any such Transfer Taxes are assessed at any time thereafter, then all such Transfer Taxes associated with the Share Purchase shall be paid by Buyer at Closing or, if assessed at any time thereafter, shall be paid promptly by Buyer following such assessment. Buyer and the Sellers agree to provide each other reasonable assistance in the preparation and filing of any kind and all required Transfer Tax returns for or with respect to such Transfer Taxes with any and all appropriate taxing authorities.

ARTICLE 7 TERMINATION Section 7.01. Termination. This Agreement may be terminated and the Share Purchase abandoned at any time prior to the Closing: (a) by mutual written agreement of the Sellers and Buyer; (b) by either the Sellers or Buyer, if any Governmental Entity shall have issued an order, decree or ruling or taken any other action (which order, decree or ruling or other action each party hereto shall use its reasonable best efforts to have vacated or reversed), in each case permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and non-appealable; provided, however, that neither party hereto shall be permitted to terminate this Agreement pursuant to this Section 7.01(b) unless and until such party shall have complied with all of its obligations set forth in Section 5.01(f) hereof; 25 (c) by either the Sellers or Buyer on July 9, 2005, if the Closing has not occurred on or before the Outside Date; provided that the right to terminate this Agreement pursuant to this Section 7.01(c) shall not be available to any party whose breach of any provision of this Agreement results in the failure of the Closing to have occurred by such time; provided further that the right to terminate this Agreement pursuant to this Section 7.01(c) shall not be available to Buyer unless and until Buyer shall have complied with all of its obligations set forth in Section 5.01(f) hereof; (d) by Buyer, if Parent or the Sellers shall have breached or failed to perform any obligation, agreement, covenant, representation or warranty on the part of Parent or the Sellers set forth in this Agreement, which breach or failure to perform (i) prevents the conditions set forth in Sections 6.01 and 6.02 from being satisfied, and (ii) shall not have been cured within ten (10) Business Days of notice from Buyer (if such breach is reasonably capable of being cured in such 10-Business Day period); (e) by Parent or the Sellers, if Buyer shall have breached or failed to perform any obligation, agreement, covenant, representation or warranty on the part of Buyer set forth in this Agreement, which breach or failure to perform (i) would prevent the conditions set forth in Sections 6.01 and 6.03 of this Agreement from being satisfied, and (ii) shall not have been cured within ten (10) Business Days of notice from the Sellers (if such breach is reasonably capable of being cured in such 10-Business Day period), or if Buyer fails to make any of the payments required under Section 5.01(f) hereof as and when due; (f) by Parent or the Sellers, if, in the Sellers' exercise of their fiduciary duties, the Sellers determine, prior to the entry of the Sale Order, that consummation of the transactions contemplated hereunder is not in the best interests of their chapter 11 estates and creditors, in which event Buyer shall be deemed to have waived all claims, damages, actions and causes of action of whatever kind and nature (including any claims for attorney's fees), whether known or unknown, fixed or contingent, matured or unmatured, liquidated or unliquidated or otherwise, arising from, related to, or concerning this Agreement (other than with respect to the Sellers' payment obligation to Buyer pursuant to Section 5.01(f) hereof); (g) by Parent or the Sellers, if Parent and the Sellers have complied with the covenant contained in Section 5.08(e) and the Bankruptcy Court (i) does not enter the Sale Order by the date that is forty five (45) days after the date of the Sale Motion or (ii) denies issuance of the Sale Order within such forty five (45) day period; 26 (h) by Buyer, if Parent and the Sellers have not executed and delivered this Agreement by 6:00 p.m. New York City time on March 12, 2004; (i) by Buyer, if (i) the Sale Motion has not been filed with the Bankruptcy Court on or before March 19, 2004 or (ii) the Bankruptcy Court does not enter the Sale Order by the date that is thirty (30) days after the date of the Sale Motion; (j) by Buyer, if Parent or the Sellers (i) breach the covenant contained in Section 5.08(e) or (ii) either directly or through their representatives, solicit or initiate any discussions or negotiations, or engage in active negotiations, or enter into any agreement, with any third party with respect to a purchase and sale, directly or indirectly, of the Shares, the Common Stock or the business of Embratel. For the avoidance of doubt, engaging in discussions with a third party which are solely intended to clarify the terms or conditions of any unsolicited proposal received from a third party or to reject such proposal shall not constitute engaging in active negotiations; and (k) by Buyer, if any of the matters set forth in Schedule 6.02(e) shall not be true and correct such that the condition set forth in Section 6.02(e) hereof would not be satisfied and such failure to be true and correct is not reasonably capable of being cured by the Closing Date. In the event of termination and abandonment by Buyer or the Sellers, or both, pursuant to Section 7.01 hereof, written notice thereof shall forthwith be given to the other party or parties, and this Agreement shall terminate, and the Share Purchase shall be abandoned, without further action by Buyer, Parent or the Sellers. Section 7.02. Effect of Termination. If this Agreement is terminated pursuant to Section 7.01, this Agreement shall become void and of no effect with no liability on the part of any party (or any shareholder, director, officer, employee, agent, consultant, representative or Affiliate of such party) to the other party hereto; provided that nothing in this Section 7.02 shall (i) relieve Buyer or the Sellers of any liability for a breach of this Agreement prior to the date of termination or relieve either party from its obligation to make any payments to the extent provided in Section 5.01(f) or (ii) require the Sellers to return any payments theretofore made by Buyer other than in accordance with Section 5.01(f) hereof; provided further that in the event that this Agreement is validly terminated pursuant to Section 7.01 hereof under circumstances where the Sellers are not required to return to Buyer any of the amounts specified in Section 5.01(f), then none of the parties hereto shall have any further liability hereunder. The damages recoverable by the non-breaching party shall include all attorneys' fees reasonably incurred by such party in connection with the transactions contemplated hereby. The provisions of Section 7.01 and this Section 7.02, and of Article 8 and the Confidentiality Agreement shall survive any termination hereof pursuant to Section 7.01. 27 ARTICLE 8 MISCELLANEOUS Section 8.01.
