WHEREAS, as of the date hereof, Terremark Holdings, Inc., a Florida corporation ("Terremark") and the Company have entered into that certain Agreement and Plan of Merger pursuant to which Terremark shall merge (the "Merger")with and into the Company with the Company being the surviving entity (the "Merger Agreement"); WHEREAS, as of the date hereof, Terremark and certain of its Affiliates (the "Terremark Group") and Purchaser and its Affiliates (the "Vistagreen Group") have entered into that certain Contract for Purchase and Sale, pursuant to which Terremark is purchasing, and the Vistagreen Group is selling, the general and limited partnership interests (the "Partnership Interests") of Terremark Center, Ltd., a Florida limited partnership (the "Purchase Contract"); WHEREAS, upon the closing of the Purchase Contract, the Vistagreen Group will receive certain promissory notes in the aggregate amount of $56,000,000 less the outstanding balance of the first mortgage loan on the property legally described in Exhibit A to the Purchase Contract (the "Property") in favor of Principal Mutual Insurance Company, in payment of the purchase price for the sale of the Partnership Interests to the Terremark Group (the "Note"); and WHEREAS, in connection with the sale of the Property, the Note shall be required to be satisfied in full and, subject to certain conditions, all such proceeds so paid to satisfy the Note in full ("Note Proceeds") shall be used to purchase certain shares of the Company as set forth herein. NOW, THEREFORE, in consideration of the premises and of the mutual covenants, representations, warranties, conditions and agreements herein contained, the parties hereto agree as follows (all capitalized terms not herein defined shall have the same meaning as set forth in the Merger Agreement): ARTICLE I PURCHASE AND SALE OF STOCK 1.1. Note Proceeds. The parties acknowledge that for the closing of the transactions contemplated by this Agreement (the "Closing") to occur, the Property must have been sold. Upon the sale of the Property, the Terremark Group shall be required to pay the Note Proceeds into an interest-bearing account in the name of ACGDI, Inc., Terremark at Bayshore, Inc. and Terremark Centre, Inc. or their permitted assignees, who at such time hold the note (the "Holders"), at Northern Trust Bank of Florida, N.A. (the "Escrow Account"). There shall be two authorized signatories (the "Representatives") with respect to such Escrow Account, one representing the Holders and the other representing Terremark. The initial Representative of the Holders shall be Joel J. Karp, Esq., and the initial Representative of Terremark shall be Brian K. Goodkind, Esq. Any withdrawals from the Escrow Account shall require the signature of both such Representatives. The Holders and Terremark, respectively, agree to cause their respective Representatives to disburse funds from the Escrow Account in accordance with the provisions of this Agreement. 1.2. Purchase and Sale of Post-Merger Common Stock. Upon the Merger Agreement Closing, the Surviving Corporation will sell to the Vistagreen Group and the Vistagreen Group will purchase from the Surviving Corporation such number of Registered shares of Post Merger Common Stock of the Surviving Corporation which represents 35% of the issued and outstanding Post-Merger Common Stock of the Surviving Corporation on a fully diluted basis ("Holders Stock"). As used herein, any calculation of shares on a "fully diluted basis" shall mean a calculation of share ownership that assumes that all options granted under any incentive or other plan of the Company have been exercised, that all warrants to purchase securities of the Company or the Surviving Corporation have been exercised and that all rights to convert any security or other instrument, including, without limitation, Series E and G Preferred Stock of the Company, into Common Stock or Post Merger Common Stock have been exercised, each such exercise to be deemed to have occurred immediately prior to the issuance of the Post-Merger Common Stock to the Holders. As used herein "Registered" shares shall mean shares which are registered for lawful public sale pursuant to a registration statement which has been declared effective by the SEC (and with respect to which no stop order suspending effectiveness of the same shall be in effect and no proceedings for such purpose shall be pending before or threatened by the SEC) under applicable federal and state securities laws and which have been approved for listing on the AMEX, subject to final notice of issuance. The purchase price to be paid by the Vistagreen Group for the Holders Stock shall be an amount equal to the Note Proceeds, together with all interest earned thereon. At the Closing, the Surviving Corporation shall deliver to the Vistagreen Group certificates in the aggregate representing the Holders Stock, which certificates shall be in such denominations as the Vistagreen Group reasonably request, such request to be delivered to the Surviving Corporation in writing at least three (3) business days prior to the Closing. Notwithstanding anything herein to the contrary, if the Merger Agreement Closing has not occurred on or before December 31, 2000, then the obligation of the Vistagreen Group to purchase the Holders Stock shall immediately terminate and be of no further force and effect. In such event, on the first business day in January 2001, Terremark and the Holders shall each cause their respective Representatives to disburse all funds which then remain in the Escrow Account to the Vistagreen Group in accordance with the Purchase Contract and such instructions as the Vistagreen Group shall deliver to such Representatives. 1.3. Closing. The Closing shall take place at the same place as and immediately following the Merger Agreement Closing. Notwithstanding anything herein to the contrary, in the event that any condition precedent to the obligation of the Vistagreen Group to purchase the Holders Stock hereunder is not satisfied as of the Merger Agreement Closing, the Vistagreen Group shall not be required to so purchase the Holders Stock regardless of whether Terremark and the Company elect to effect the Merger. Without limiting the foregoing, no waiver by Terremark of any condition precedent to Terremark's obligation to effect the Merger shall constitute or be deemed a waiver of the same condition by the Vistagreen Group. ARTICLE II REPRESENTATIONS AND WARRANTIES 2.1. Representations and Warranties of the Company. The Company hereby represents and warrants to the Vistagreen Group as follows: (a) Due Organization, Good Standing and Corporate Power. Each of the Company and its Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and each such corporation has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as now being conducted. Each of the Company and its Subsidiaries is duly qualified or licensed to do business and is in good standing in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification necessary, except in such jurisdictions where the failure to be so qualified or licensed and in good standing would not have a Material Adverse Effect on the Company. For the purposes of this Agreement, "Material Adverse Effect" on any Person means a material adverse effect on the business, properties, assets, liabilities, operations, results of operations, condition (financial or otherwise) or prospects of the Person and its Subsidiaries taken as a whole (i) except to the extent resulting from (A) any change in general United States or global economic conditions or general economic conditions in industries in which the Person competes, or (B) the announcement of the transaction contemplated herein or any action required to be taken pursuant to the terms hereof, and (ii) except that the term Material Adverse Effect shall not include, with respect to the Company (A) any decreases in the Company's stock price in and of itself or (B) any deterioration in the Company's financial condition which is a direct and proximate result of its agreements with Hebei United Telecommunication Equipment Co. The term "Subsidiary," as used in this Agreement, refers to any Person in which the Company owns any equity interest and shall include all joint ventures. (b) Authorization and Validity of Agreement. The Company has full corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby. The execution, delivery and performance of this Agreement by the Company, and the consummation by it of the transactions contemplated hereby, have been duly authorized and approved by its Board of Directors and no other corporate action on the part of the Company is necessary to authorize the execution, delivery and performance of this Agreement by the Company and the consummation of the transactions contemplated hereby. This Agreement has been duly executed and delivered by the Company and is a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except to the extent that such enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting the enforcement of creditors' rights generally and by general equitable principles. (c) Capitalization. (i) The authorized capital stock of the Company consists of 100,000,000 shares of Common Stock and 10,000,000 shares of preferred stock, $0.001 par value (the "Preferred Stock").

No shares of Common Stock are held in the Company's treasury. The Series G Preferred Stock converts at the option of the holder into 1,688,022 shares of Common Stock, which number of shares of Common Stock have been authorized and reserved for issuance by the Company. All issued and outstanding shares of capital stock of the Company have been validly issued and are fully paid and nonassessable, and are not subject to, nor were they issued in violation of, any preemptive rights.

The Company will authorize and reserve and hereby covenants that it will continue to reserve, free of any preemptive rights or encumbrances, a sufficient number of its authorized but previously unissued shares of Common Stock to satisfy the purchase rights of the Vistagreen Group hereunder. The Holders Stock which is being purchased by the Vistagreen Group hereunder, when issued, sold and delivered in accordance with the terms hereof, will be duly and validly issued, fully paid and non-assessable and will be issued in compliance with all applicable federal and state securities laws.

ARTICLE III REGISTRATION RIGHTS 3.1. Shelf Registration. If the Company shall receive from the holders in the aggregate of not less than twenty-five percent (25%) of the Registrable Securities (collectively, an "Initiating Holder"), at any time later than nine months after the Effective Date, a written request that the Company effect a registration of the Registrable Securities (a "Registration Requirement"), the Company will: (a) Within thirty (30) days of receipt of a Registration Request, the Company shall file a "shelf" registration statement on Form S-3, or other applicable form that is mutually satisfactory, pursuant to Rule 415 under the Securities Act (the "Shelf Registration") with respect to that portion of the Registrable Securities (which may be all but shall not be less than 25% of the Registrable Securities) included in the Registration Request. The Company agrees that the provisions of this Section 3.1(a) create a "demand" registration right for the Holders with respect to the Registrable Securities. The Company shall, subject to Section 3.1(e) hereof, use its reasonable best efforts to cause the Shelf Registration to become effective as soon as practicable after the filing thereof and shall use its reasonable best efforts to keep the Shelf Registration continuously effective from the date such Shelf Registration is effective until the date on which all Registrable Securities may be sold pursuant to Rule 144(k). (b) Subject to Section 3.2(f) hereof, the Company shall supplement or amend the Shelf Registration, (A) as required by the registration form utilized by the Company or by the instructions applicable to such registration form or by the Securities Act or the rules and regulations promulgated thereunder, and (B) to include in such Shelf Registration any additional unregistered securities that become Registrable Securities by operation of the definition thereof, unless such securities are otherwise registered under the Securities Act or may be sold pursuant to an exemption therefrom or (C) if and to the extent reasonably requested by the Holders of the Registrable Securities, provided however, that such request and any required supplement or amendment shall relate only to material information about such Holder and included in or omitted from such Shelf Registration. The Company shall furnish to the Holders of the Registrable Securities to which the Shelf Registration relates copies of any such supplement or amendment no less than five business days in advance of its use and/or filing with the Commission to allow the Holders to comment thereon. The failure of the Holders to provide written comments under such period shall be deemed agreement with such supplement or amendment. (c) The Shelf Registration may include other Securities of the Company which are held by Persons who, by virtue of agreements with the Company, are entitled to include their Securities in any such registration ("Other Stockholders"). 3.2. Expenses of Registration. All Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to this Article III (including all Registration Expenses incurred in connection with the Shelf Registration and any supplements or amendments thereto, whether or not it becomes effective, and whether all, none or some of the Registrable Securities are sold pursuant to the Shelf Registration) shall be borne by the Company (provided, however, that the Holders shall bear the expenses of advisors, including investment bankers, retained by them, except that the Company shall pay the expenses of one counsel for the Holders in an amount not to exceed $10,000), and all Selling Expenses shall be borne by the Holders of the securities so registered pro rata on the basis of the number of their shares so registered. 3.3. Registration Procedures. In the case of the registration effected by the Company pursuant to this Article III, the Company will advise the Holders in writing as to the filing of the Shelf Registration and the effectiveness thereof. The Company will: (a) furnish to each Holder, and to any underwriter designated by the Holder a reasonable number of copies of any registration statement (including all exhibits) and any prospectus forming a part thereof and any amendments and supplements thereto (including all documents incorporated or deemed incorporated by reference therein) prior to the effectiveness of such registration statement and any prospectus filed under Rule 424 under the Securities Act, which documents, other than documents incorporated or deemed incorporated by reference, will be subject to the review of the Holders and any such underwriter for a period of at least five business days, and the Company shall not file any such registration statement or such prospectus or any amendment or supplement to such registration statement or prospectus to which any Holder or any such underwriter shall reasonably object in writing, specifying in detail the nature of such objection, within five business days after the receipt thereof; a Holder shall be deemed to have reasonably objected to such filing only if the registration statement, amendment, prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission; (b) furnish to each Holder and to any underwriter designated by the Holder a reasonable number of conformed copies of the applicable registration statement and of each amendment and supplement thereto (in each case including all exhibits) and such number of copies of the prospectus forming a part of such registration statement and prospectus filed under Rule 424 under the Securities Act, and such other documents, including without limitation documents incorporated or deemed to be incorporated by reference prior to the effectiveness of such registration, as each of the Holders or any such underwriter from time to time may reasonably request; (c) to the extent practicable, promptly prior to the filing of any document that is to be incorporated by reference into any registration statement or prospectus forming a part thereof subsequent to the effectiveness thereof, and in any event no later than the date such document is filed with the Commission, provide copies of such document to the Holders and to any underwriter, if requested, and make representatives of the Company available for discussion of such document and other customary due diligence matters; (d) make available at reasonable times for inspection by the Holders, any underwriter and any attorney or accountant retained by the Holders or any such underwriter all financial and other records, pertinent corporate documents and properties of the Company and cause the officers, directors and employees of the Company to supply all information reasonably requested by the Holders and any such underwriters, attorneys or accountants in connection with such registration subsequent to the filing of the applicable registration statement and prior to the effectiveness of the applicable registration statement; (e) use its reasonable best efforts (x) to register or qualify all Registrable Securities and other securities covered by such registration under such other securities or blue sky laws of such States of the United States of America where an exemption is not available and as the sellers of Registrable Securities covered by such registration shall reasonably request, (y) to keep such registration or qualification in effect for so long as the applicable registration statement remains in effect, and (z) to take any other action which may be reasonably necessary or advisable to enable such sellers to consummate the disposition in the United States of the securities to be sold by such sellers, except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction where it is not so qualified, or to subject itself to taxation in any such jurisdiction, or to execute a general consent to service of process in effecting such registration, qualification or compliance, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act or applicable rules or regulations thereunder; (f) promptly notify each Holder of Registrable Securities covered by a registration statement (A) upon discovery that, or upon the happening of any event as a result of which, the prospectus forming a part of such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state any 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, (B) of the issuance by the Commission of any stop order suspending the effectiveness of such registration statement or the initiation of proceedings for that purpose, (C) of any request by the Commission for (1) amendments to such registration statement or any document incorporated or deemed to be incorporated by reference in any such registration statement, (2) supplements to the prospectus forming a part of such registration statement or (3) additional information, or (D) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction in which the Company has agreed hereunder to qualify such securities for sale or the initiation of any proceeding for such purpose, and at the request of any such Holder promptly prepare and furnish to it a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include an untrue statement of a material fact or omit to state 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; (g) use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of any such registration, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in which the Company has agreed hereunder to qualify such securities for sale; (h) if requested by any Initiating Holder, or any underwriter, promptly incorporate in such registration statement or prospectus, pursuant to a supplement or post effective amendment if necessary, such information as the Initiating Holder and any underwriter may reasonably request to have included therein relating to the "plan of distribution" of the Registrable Securities, the principal amount or number of shares of Registrable Securities being sold to such underwriter, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and make all required filings of any such prospectus supplement or post-effective amendment as soon as practicable after the Company is notified of the matters to be incorporated in such prospectus supplement or post effective amendment; (i) provide promptly to the Holders upon request any document filed by the Company with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act; and (j) use its reasonable best efforts to cause all Registrable Securities included in any registration pursuant hereto to be listed on each securities exchange on which securities of the same class are then listed, or, if not then listed on any securities exchange, to be eligible for trading in any over-the-counter market or trading system in which securities of the same class are then traded. 3.4. Indemnification. (a) The Company will indemnify each of the Holders, as applicable, each of its officers, directors, members and partners, and each person controlling each of the Holders, with respect to each registration which has been effected pursuant to this Article III, and each underwriter, if any, and each person who controls any underwriter, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document (including any related registration statement, notification or the like) incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or the Exchange Act or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each of the Holders, each such underwriter and each person who controls any such underwriter, each of its officers, directors, members and partners, and each person controlling each of the Holders for any legal and any other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by the Holders and stated to be specifically for use therein. It is agreed that the indemnity agreement contained in this Section 3.4(a) shall not apply to any amounts paid in settlement of any such claims, loss, damage, liability or expense if such settlement is effected without the consent of the Company (which consent has not been unreasonably withheld). (b) Each of the Holders will, if Registrable Securities held by it are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers and each underwriter, if any, of the Company's securities covered by such a registration statement, each person who controls the Company or such underwriter, each Other Stockholder and each of their officers, directors, members and partners, and each person controlling such Other Stockholder against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document made by such Holder, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements by such Holder therein not misleading, and will reimburse the Company and such Other Stockholders, directors, officers, partners, members, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by such Holder and stated to be specifically for use therein; provided, however, that the obligations of each of the Holders hereunder and under clause (f) below shall be limited to an amount equal to the net proceeds to such Holder of securities sold as contemplated herein. It is agreed that the indemnity agreement contained in this Section 3.4(b) shall not apply to any amount paid in settlement of any such claim, loss, damage, liability or expense if such settlement is effected without the consent of the majority of the Holders (which consent will not be unreasonably withheld). (c) Each party entitled to indemnification under this Section (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such defense at such party's expense (unless the Indemnified Party shall have reasonably concluded, based upon an opinion of counsel, that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in such action, in which case the fees and expenses of one such counsel for all Indemnified Parties shall be at the expense of the Indemnifying Party), and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 3 unless the Indemnifying Party is materially prejudiced thereby. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party (which consent shall not be unreasonably withheld or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom. (d) If the indemnification provided for in this Section 3.4 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue (or alleged untrue) statement of a material fact or the omission (or alleged omission) to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with any underwritten public offering contemplated by this Agreement are in conflict with the foregoing provisions, the provisions in such underwriting agreement shall be controlling. (f) The foregoing indemnity agreement of the Company and Holders is subject to the condition that, insofar as they relate to any loss, claim, liability or damage made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time the registration statement in question becomes effective or the amended prospectus filed with the Commission pursuant to Commission Rule 424 (the "Final Prospectus"), such indemnity or contribution agreement shall not inure to the benefit of any underwriter or Holder (but only if such Holder was required to deliver such Final Prospectus) if a copy of the Final Prospectus was furnished to the underwriter and was not furnished to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act. 3.5. Information by the Holders. Each of the Holders holding securities included in any registration shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Article III. 3.6. Holdback Agreement; Postponement. Notwithstanding the provisions of this Article III, if the Board of Directors of the Company determines in good faith that it is in the best interests of the Company (A) not to disclose the existence of facts surrounding any proposed or pending acquisition, disposition, strategic alliance or financing transaction involving the Company or (B) for any purpose relating to: (aa) a registration of equity securities of the Company, (bb) a registration of convertible securities of the Company (including any underlying equity securities), (cc) a registration of any securities sold pursuant to a Rule 144A transaction, or (dd) a registration of any securities relating to a transaction described in Rule 145(a), to suspend the registration rights set forth herein, the Company may, by notice to the Holders in accordance with the notice provisions hereof, suspend the rights of the Holders to make sales pursuant to the Shelf Registration for such a period of time as the Board of Directors may reasonably determine, provided however, that such suspension shall be terminated by the Company as soon as is reasonably practicable. 3.7. Assignment. The registration rights set forth in Article III hereof may be assigned, in whole or in part, to any transferee of Registrable Securities (who shall be considered thereafter to be a Holder (provided that any transferee who is not an affiliate of Holder shall be a Holder only with respect to such Registrable Securities so acquired and any stock of the Company issued as a dividend or other distribution with respect to, or in exchange for or in replacement of, such Registrable Securities) and shall be bound by all obligations and limitations of this Agreement). 3.8. Remedies. Each Holder of Registrable Securities, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. 3.9. Lockup. Notwithstanding the date of effectiveness of the Registration Statement filed pursuant to Section 3.1 hereof, the Holders agree that, except as provided below, no sale, offer to sell, pledge or other disposition of any interest in the Holders Stock shall be made by any Holder prior to the expiration of one (1) year after the Effective Time; provided, however, that nothing herein contained shall preclude (i) open market sales pursuant to Rule 144, or (ii) sales by any member of the Vistagreen Group to another member of such Group or any family member or Affiliate of any member of such Group or to Terremark or any Affiliate of Terremark.

NOW THEREFORE, for good and valuable consideration, the parties hereto agree as follows (all capitalized terms not herein defined shall have the meaning set forth in the Stock Purchase Agreement): 1.

Upon and subject to the Merger Agreement Closing, the Surviving Corporation will sell to the Vistagreen Group and the Vistagreen Group will purchase from the Surviving Corporation such number of shares of duly authorized, validly issued, fully paid and non-assessable Post Merger Common Stock of the Surviving Corporation which represents 35% of the issued and outstanding Post-Merger Common Stock of the Surviving Corporation on a fully diluted basis after giving effect to such issuance ("Holders Stock").

At the Closing,. the Surviving Corporation shall deliver to the Vistagreen Group original certificates in the aggregate representing the Holders Stock (with stamps or other evidence of payment of all taxes payable in respect of such issuance affixed thereto or accompanying the same), which certificates shall be in such denominations as the Vistagreen Group reasonably request, such request to be delivered to the Company (which shall be deemed notice to the Surviving Corporation) in writing at least three (3) business days prior to the Closing. Notwithstanding anything herein to the contrary, if the Merger Agreement Closing has not occurred on or before December 31, 2000 (time being of the essence of this provision), then the obligation of the Vistagreen Group to purchase the Holders Stock and the Surviving Corporation's right to sell the Holders Stock to the Vistagreen Group shall immediately terminate (without liability to any party) and be of no further force and effect. In such event, on the first business day in January 2001, Terremark and the Holders shall each cause their respective Representatives to disburse the Note Proceeds which then remain in the Escrow Account to the Vistagreen Group in accordance with the Purchase Contract and such instructions as the Vistagreen Group shall deliver to such Representatives.

The following section is added as a new Section 2.2(c): Investment Intent. The Vistagreen Group represents and warrants that it is purchasing the Post Merger Common Stock issued to it for investment purposes and not with a view to distribution thereof and agrees that it shall not make any sale, transfer or other disposition of its Post Merger Common Stock in violation of any applicable securities law. 5.

Section 3.9 is hereby revised and restated in its entirety to read as follows: 3.9 Lockup. Notwithstanding the date of effectiveness of the Registration Statement filed pursuant to Section 1.2 hereof, the Holders agree that, except as provided below, no sale, offer to sell or other disposition of any interest in the Holders Stock shall be made by any Holder (without the consent of the Surviving Corporation, to be given or withheld in the Surviving Corporation's sole and absolute discretion) prior to the expiration of one (1) year after the Merger Agreement Closing; provided, however, that nothing herein contained shall impair or affect the Holder's rights to sell Holders Stock pursuant to I) open market sales in such amounts and at such times as would be permitted under the volume limitation of Rule 145, as if such rule were applicable, or (ii) sales by any member of the Vistagreen Group to another member of such Group or any family member or Affiliate of any member of such Group or to Terremark or any affiliate of Terremark (a "Permitted Transferee").

Section 4.1 is hereby revised and restated in its entirety to read as follows: United States Real Property Interests. The Company covenants and agrees that for so long as the Vistagreen Group holds, in the aggregate, Holders Stock acquired pursuant to this Agreement representing at least 1% of the outstanding shares of Common Stock of the Company, the Company shall not be or become a United States Real Property Holding Corporation as defined in Section 897(c)(2) of the Code nor shall the Holders Stock acquired pursuant to this Agreement be or become a United States Real Property Interest as defined in Section 897(c)(1)(A)(ii) of the Code.

Any notice conforming with or under Treasury Regulation Section 1.897-2(h) need to address the status of the Company as a United States Real Property Holding Corporation and the status of the Company Shares as a United States real property Interest only from a date that is no earlier than the date of the Effective Time. These covenants shall in all respects survive the Closing of this Agreement. 8. The introductory paragraph of Section 5.1(d) is hereby revised and restated in its entirety to read as follows (with subsections (i), (ii) and (iii) remaining unchanged: United Stated Real Property Holding Corporation. Neither the Surviving Corporation nor the Company is, as of the Effective Time, a United States real property holding corporation (as defined in Section 897(c)(2) of the Code), and the Holders Stock to be acquired by the Holders, at the Effective Time, does not constitute a United States real property interest (as defined in Section 897(c)(1)(A)(ii) of the Code) ("USRPHC Condition Precedent"). To assure that the USRPHC Condition Precedent has been met the following shall be delivered to the Holders at Closing: 9. Section 6.1(b) is hereby deleted in its entirety and the remaining subsections of Section 6.1 are renumbered accordingly. 10. Each of the parties hereto agrees that it will use its commercially reasonable best efforts to do all things reasonably necessary to consummate the transactions contemplated hereby. 11.

Except as specifically amended by this Amendment, all terms and conditions of the Stock Purchase Agreement shall remain unchanged and in full force and effect. 14.
