The Company shall not be required to effect any such transfer prior to the receipt of such favorable opinion; provided that if the proposed transfer is governed by Rule 144 promulgated by the SEC, or any successor rule, such opinion shall not be required, but the Company may prevent such transfer until it receives evidence satisfactory to it and its counsel that the transfer complies with Rule 144. Each transfer shall comply with all applicable SEC rules and applicable state securities laws. 6.3 PERMITTED TRANSFERS.

CERTAIN COVENANTS. 7.1 PREEMPTIVE RIGHTS. 7.1.1 Purchaser shall have the right to subscribe to any additional (i) issuances of shares of capital stock of the Company, (ii) issuances of securities convertible into shares of capital stock of the Company, or (iii) grants of options to purchase shares of capital stock of the Company, other than grants to employees, directors or consultants of the Company (and the issuance of shares upon exercise of such options), for cash, on the same terms of such offerings to the extent equal to the proportion which the number of shares of Stock then held by Purchaser bears to the Company's fully-diluted capitalization (on an as-converted and as-exercised basis). Such right is exercisable within ten (10) days after the receipt of written notice relating to such issuances by the Purchaser. Such right extends to the same proportion of the new issue of shares, convertible securities or options as the Purchaser's proportion of the outstanding shares. 7.1.2 Purchaser's right to purchase new issues of shares or convertible securities or options does not extend to (i) the issuance of shares upon the conversion or exercise of options or other convertible securities either (A) outstanding on the date hereof, or (B) with respect to which options or other convertible securities Purchaser had preemptive rights under this SECTION 7.1, or (ii) securities issued solely in exchange for shares, convertible securities or options issued in connection with any merger, reorganization or acquisition (including, without limitation, shares of Stock issued in connection with the pending merger of WorldxChange Limited (New Zealand)). 7.1.3 The preemptive rights held by the Purchaser pursuant to this SECTION 7.1 supersede and replace the preemptive rights held by the Purchaser pursuant to the 11 First Atocha Agreement such that the preemptive rights held by the Purchaser pursuant to the First Atocha Agreement shall terminate as of the Initial Closing. 7.1.4 The preemptive rights held by the Purchaser pursuant to this SECTION 7.1 shall terminate immediately prior to the closing of an initial public offering of the Company's securities and shall not apply to any issuance of securities in such offering. 7.2 REGISTRATION RIGHTS. The Company and Purchaser, concurrently with the Initial Closing, shall execute and deliver the New Registration Rights Agreement. 7.3 BOARD MATTERS. Beginning on and contingent upon the occurrence of the Initial Closing Date and until the earlier to occur of (i) such time as the Purchaser and Gold & Appel, collectively, do not own at least five percent of the issued and outstanding Stock, or (ii) such time as the Company becomes subject to the reporting requirements of Section 13 of the Exchange Act, the Purchaser shall have the right to designate one (1) nominee to the Company's Board of Directors. Notwithstanding the foregoing, (i) prior to such time as the Company becomes subject to Section 13 of the Exchange Act, such nominee shall be Thomas Ciritto, unless Thomas Ciritto is unable to serve due to a physical or mental incapacity, in which case the Purchaser has the right to designate another nominee, and (ii) the Purchaser shall have the right to designate one (1) nominee to the Company's initial Board of Directors after the Company becomes subject to Section 13 of the Exchange Act, provided that if such nominee is not Thomas Ciritto, the nominee shall be subject to the approval of the Company. 7.4 RULE 144 FILING. After the Company's Common Stock is registered under the Exchange Act, and until the Initial Shares and the Remaining Shares held by Purchaser have all been publicly sold or are eligible for sale under Rule 144(k) under the Securities Act, the Company shall use best efforts to file the reports required under Rule 144(c)(1) under the Securities Act in order to permit sales of the Initial Shares and Remaining Shares by Purchaser pursuant to Rule 144. 7.5 HSR FILINGS. The Company and the Purchaser each agree to use best efforts to cause the HSR Filings to be made promptly after the execution and delivery of this Agreement.

INDEMNIFICATION. 8.1 OBLIGATIONS OF THE COMPANY. The Company agrees to indemnify and hold harmless the Purchaser from and against any and all Losses of the Purchaser based upon or arising from any inaccuracy in or breach or nonperformance of any of the representations, warranties, or covenants made or obligations undertaken by the Company in this Agreement. 8.2 OBLIGATIONS OF THE PURCHASER. The Purchaser agrees to indemnify and hold harmless the Company from and against any and all Losses of the Company based upon or arising from, any inaccuracy in or breach or nonperformance of any of the representations, warranties or covenants made by the Purchaser in this Agreement. 12 8.3 PROCEDURE. 8.3.1 NOTICE. Any party seeking indemnification with respect to any Loss shall give notice to the party required to provide indemnity hereunder (the "INDEMNIFYING PARTY"). 8.3.2 DEFENSE. If any claim, demand or liability is asserted by any third party against any Indemnified Party, the Indemnifying Party shall upon the written request of the Indemnified Party, defend any actions or proceedings brought against the Indemnified Party in respect of matters embraced by the indemnity. If, after a request to defend any action or proceeding, the Indemnifying Party does not defend the Indemnified Party, a recovery against the latter suffered by it in good faith, is conclusive in its favor against the Indemnifying Party, provided however that, if the Indemnifying Party has not received reasonable notice of the action or proceeding against the Indemnified Party, or is not allowed to control its defense, judgment against the Indemnified Party is only presumptive evidence against the Indemnifying Party. The parties shall cooperate in the defense of all third party claims which may give rise to Indemnifiable Claims hereunder. In connection with the defense of any claim, each party shall make available to the party controlling such defense, any books, records or other documents within its control that are reasonably requested in the course of such defense. 8.4 EXCLUSIVE REMEDY. This SECTION 8 shall be the exclusive remedy of the parties for any Loss of such party based upon or arising from any inaccuracy in or breach or nonperformance of any of the representations, warranties, or covenants made by any other party to this Agreement.
