     INTELLECTUAL PROPERTY SECURITY AGREEMENT (as amended, amended and restated, supplemented or
otherwise modified from time to time, the “IP Security Agreement”) dated June 24, 2009, is made by
the Persons listed on the signature pages hereof (collectively, the “Grantors”) in favor of U.S.
Bank National Association, (“US Bank”), as collateral trustee (the “Collateral Trustee”) for the
Secured Parties (as defined in the Indenture referred to below).

     WHEREAS, Terremark Worldwide, Inc., a Delaware corporation (the “Company”) and the Grantors
have entered into an Indenture dated as of June 24, 2009 (as amended, amended and restated,
supplemented or otherwise modified from time to time, the “Indenture”), with The Bank of New York
Mellon Trust Company, N.A., as trustee, (the “Trustee”) and the Guarantors party thereto.

     WHEREAS, the Company and the Grantors have entered into a Collateral Trust Agreement with the
Collateral Trustee, the Trustee and the other parties party thereto (the “Collateral Trust
Agreement”). Terms defined in the Indenture or the Collateral Trust Agreement and not otherwise
defined herein are used herein as defined in the Indenture or Collateral Trust Agreement.

     WHEREAS, as a condition precedent to the entry into the Parity Lien Documents by the Parity
Lien Representatives and the other holders of Parity Lien Obligations, each Grantor has executed
and delivered that certain Security Agreement dated June 24, 2009, made by the Grantors to the
Collateral Trustee (as amended, amended and restated, supplemented or otherwise modified from time
to time, the “Security Agreement”).

     WHEREAS, under the terms of the Security Agreement, the Grantors have granted to the
Collateral Trustee, for the ratable benefit of the Secured Parties, a security interest in, among
other property, certain intellectual property of the Grantors, and have agreed as a condition
thereof to execute this IP Security Agreement for recording with the U.S. Patent and Trademark
Office, the United States Copyright Office and other governmental authorities.

     NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, each Grantor agrees as follows:

     SECTION 1. Grant of Security. Each Grantor hereby grants to the Collateral Trustee
for the ratable benefit of the Secured Parties a security interest in all of such Grantor’s right,
title and interest in and to the following (the “Collateral”):

     (i) the patents and patent applications set forth in Schedule A hereto (the
“Patents”);

     (ii) the trademark and service mark registrations and applications set forth in
Schedule B hereto (provided that no security interest shall be granted in United
States intent-to-use trademark applications to the extent that, and solely during
the period in which, the grant of a security interest therein would impair the
validity or enforceability of such intent-to-use trademark applications under
applicable federal law), together with the goodwill symbolized thereby (the
“Trademarks”);

     (iii) all copyrights, whether registered or unregistered, now owned or
hereafter acquired by such Grantor, including, without limitation, the copyright
registrations and applications and exclusive copyright licenses set forth in
Schedule C hereto (the “Copyrights”);

 

 

     (iv) all reissues, divisions, continuations, continuations-in-part, extensions,
renewals and reexaminations of any of the foregoing, all rights in the foregoing
provided by international treaties or conventions, all rights corresponding thereto
throughout the world and all other rights of any kind whatsoever of such Grantor
accruing thereunder or pertaining thereto;

     (v) any and all claims for damages and injunctive relief for past, present and
future infringement, dilution, misappropriation, violation, misuse or breach with
respect to any of the foregoing, with the right, but not the obligation, to sue for
and collect, or otherwise recover, such damages; and

     (vi) any and all proceeds of, collateral for, income, royalties and other
payments now or hereafter due and payable with respect to, and supporting
obligations relating to, any and all of the Collateral of or arising from any of the
foregoing.

     SECTION 2. Security for Obligations. The grant of a security interest in the
Collateral by each Grantor under this IP Security Agreement secures the payment of all Secured
Obligations of such Grantor now or hereafter existing under or in respect of the Parity Lien
Documents, whether direct or indirect, absolute or contingent, and whether for principal,
reimbursement obligations, interest, premiums, penalties, fees, indemnifications, contract causes
of action, costs, expenses or otherwise. Without limiting the generality of the foregoing, this IP
Security Agreement secures, as to each Grantor, the payment of all amounts that constitute part of
the Secured Obligations and that would be owed by such Grantor to any Secured Party under the
Parity Lien Documents but for the fact that such Secured Obligations are unenforceable or not
allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving a
Grantor.

     SECTION 3. Recordation. Each Grantor authorizes and requests that the Register of
Copyrights, the Commissioner for Patents and the Commissioner for Trademarks and any other
applicable government officer record this IP Security Agreement.

     SECTION 4. Execution in Counterparts. This IP Security Agreement may be executed in
any number of counterparts, each of which when so executed shall be deemed to be an original and
all of which taken together shall constitute one and the same agreement.

     SECTION 5. Grants, Rights and Remedies. This IP Security Agreement has been entered
into in conjunction with the provisions of the Security Agreement. Each Grantor does hereby
acknowledge and confirm that the grant of the security interest hereunder to, and the rights and
remedies of, the Collateral Trustee with respect to the Collateral are more fully set forth in the
Security Agreement, the terms and provisions of which are incorporated herein by reference as if
fully set forth herein.

     SECTION 6. Governing Law. This IP Security Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York without regard to its conflict of
law principles that would cause the law of another jurisdiction to apply (other than Sections
5-1401 and 5-1402 of the New York General Obligations Law.

     This Collateral Trust Agreement (this “Agreement”) is dated as of June 24, 2009 and is by and
among Terremark Worldwide, Inc., a Delaware corporation (the “Company”), the Guarantors from time
to time party hereto, The Bank of New York Mellon Trust Company, N.A., as Trustee (as defined
below), the other Secured Debt Representatives from time to time party hereto, and U.S. Bank
National Association, as Collateral Trustee (in such capacity and together with its successors in
such capacity, the “Collateral Trustee”).

RECITALS

     The Company intends to issue 12% Senior Secured Notes due 2017 (together with any additional
notes issued under the Indenture (as defined below) and any exchange notes related to such notes
and additional notes, the “Notes”) in an aggregate principal amount of $420,000,000 pursuant to an
Indenture dated as of the date hereof (as amended, supplemented, amended and restated or otherwise
modified and in effect from time to time, the “Indenture”) among the Company, the Guarantors party
thereto from time to time and The Bank of New York Mellon Trust Company, N.A., as trustee (in such
capacity and together with its successors in such capacity, the “Trustee”).

     The Company and the Guarantors intend to secure the Obligations under the Notes, the
Guarantees of the Notes and the Indenture and any future Parity Lien Debt and any future Junior
Lien Debt, with Liens on all present and future Collateral to the extent that such Liens have been
provided for in the applicable Security Documents.

     This Agreement sets forth the terms on which each Secured Party has appointed the Collateral
Trustee to act as the collateral trustee for the present and future holders of the Secured
Obligations to receive, hold, maintain, administer and distribute the Collateral at any time
delivered to the Collateral Trustee or the subject of the Security Documents, and to enforce the
Security Documents and all interests, rights, powers and remedies of the Collateral Trustee with
respect thereto or thereunder and the proceeds thereof.

     Capitalized terms used in this Agreement have the meanings assigned to them above or in
Article 1 below.

     In consideration of the premises and the mutual agreements herein set forth, the receipt and
sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as
follows:

ARTICLE 1.DEFINITIONS; PRINCIPLES OF CONSTRUCTION

     SECTION 1.1 Defined Terms. The following terms will have the following meanings:

     “Act of Required Debtholders” means, as to any matter at any time:

     (1) prior to the Discharge of Parity Lien Obligations, a direction in writing delivered
to the Trustee and the Collateral Trustee by or with the written consent of the holders of
Parity Lien Debt representing the Required Parity Lien Debtholders; and

Terremark — Collateral Trust Agreement

 

 

     (2) at any time after the Discharge of Parity Lien Obligations, a direction in writing
delivered to the Collateral Trustee by or with the written consent of the holders of Junior
Lien Debt representing the Required Junior Lien Debtholders.

For purposes of this definition, (a) Secured Debt registered in the name of, or beneficially owned
by, the Company or any Affiliate of the Company will be deemed not to be outstanding and (b) votes
will be determined in accordance with Section 7.2.

     “Additional Secured Debt” has the meaning set forth in Section 3.8.

     “Additional Secured Debt Designation” means a notice in substantially the form of Exhibit
A.

     “Affiliate” of any specified Person means any other Person directly or indirectly controlling
or controlled by or under direct or indirect common control with such specified Person. For
purposes of this definition, “control,” as used with respect to any Person, means the possession,
directly or indirectly, of the power to direct or cause the direction of the management or policies
of such Person, whether through the ownership of voting securities, by agreement or otherwise;
provided that beneficial ownership of 10% or more of the Voting Stock (as defined in the Indenture)

securing the payment and performance of the Junior Lien Obligations; and

     (b) the Liens securing the Junior Lien Obligations are subject and subordinate to the

     SECTION 2.4 Restrictions on Enforcement of Junior Liens.

          (a) Until the Discharge of Parity Lien Obligations, the holders of Parity Lien Obligations
will have, subject to the exceptions set forth below in clauses (1) through (4), the exclusive
right to authorize and direct the Collateral Trustee with respect to the Security Documents and the
Collateral (including, without limitation, the exclusive right to authorize or direct the
Collateral Trustee to enforce, collect or realize on any Collateral or exercise any other right or
remedy with respect to the Collateral) and neither the provisions of the Security Documents
relating thereto (other than in accordance with this Agreement) nor any Junior Lien Representative
or holder of Junior Lien Obligations, if any, may authorize or direct the Collateral Trustee with
respect to such matters. Notwithstanding the foregoing, the holders of Junior Lien Obligations may
direct the Collateral Trustee with respect to such matters:

     (1) without any condition or restriction whatsoever, at any time after the Discharge of
Parity Lien Obligations;

     (2) as necessary to redeem any Collateral in a creditor’s redemption permitted by law
or to deliver any notice or demand necessary to enforce (subject to the prior Discharge of
Parity Lien Obligations) any right to claim, take or receive proceeds of Collateral
remaining after the Discharge of Parity Lien Obligations;

     (3) as necessary to perfect or establish the priority (subject to Parity Liens) of the
Junior Liens upon any Collateral, provided that, unless otherwise agreed to by the
Collateral Trustee in the Security Documents, the holders of Junior Lien Obligations may not
require the Collateral Trustee to take any action to perfect any Collateral through
possession or control (other than the Collateral Trustee agreeing pursuant to Section 7.4
that the Collateral Trustee as agent for the benefit of the Parity Lien Representatives and
holders of the Parity Lien Obligations will act as bailee for the Collateral Trustee for the
benefit of the Junior Lien Representatives and holders of the Junior Lien Obligations); or

     (4) as necessary to create, prove, preserve or protect (but not enforce) the Junior
Liens upon any Collateral.

          (b) Both before and during an Insolvency or Liquidation Proceeding, until the Discharge of
Parity Lien Obligations, none of the holders of Junior Lien Obligations, the Collateral Trustee
(unless acting pursuant to an Act of Required Debtholders) or any Junior Lien Representative will:

     (1) request judicial relief, in an Insolvency or Liquidation Proceeding or in any other
court, that would hinder, delay, limit or prohibit the lawful exercise or enforcement of any
right or remedy otherwise available to the holders of Parity Lien Obligations in respect of
the Parity Liens or that would limit, invalidate, avoid or set aside any Parity Lien or
subordinate the Parity Liens to the Junior Liens or grant the Junior Liens equal ranking to
the Parity Liens;

     (2) oppose or otherwise contest any motion for (A) relief from the automatic stay or
(B) any injunction against foreclosure or (C) any enforcement of Parity
Liens, in each case, made by any holder of Parity Lien Obligations or any Parity Lien
Representative in any Insolvency or Liquidation Proceeding;

Terremark — Collateral Trust Agreement

     (3) oppose or otherwise contest any lawful exercise by any holder of Parity Lien
Obligations or any Parity Lien Representative of the right to credit bid Parity Lien
Obligations at any sale of Collateral in foreclosure of Parity Liens;

     (4) oppose or otherwise contest any other request for judicial relief made in any court
by any holder of Parity Lien Obligations or any Parity Lien Representative relating to the
lawful enforcement of any Parity Lien; or

     (5) challenge the validity, enforceability, perfection or priority of the Parity Liens
with respect to the Collateral.

Notwithstanding the foregoing, both before and during an Insolvency or Liquidation Proceeding, the
holders of Junior Lien Obligations or Junior Lien Representatives may take any actions and exercise
any and all rights that would be available to a holder of unsecured claims, including, without
limitation, the commencement of an Insolvency or Liquidation Proceeding against the Company or any
Guarantor in accordance with applicable law; provided, that no holder of Junior Lien Obligations or
Junior Lien Representatives will be permitted to take any of the actions prohibited by clauses (1)
through (5) of this Section 2.4(b) or oppose or contest any order that it has agreed not to oppose
or contest under Section 2.8.

     (c) At any time prior to the Discharge of Parity Lien Obligations, and after (1) the
commencement of any Insolvency or Liquidation Proceeding in respect of the Company or any Guarantor
or (2) the Collateral Trustee and each Junior Lien Representative have received written notice from
any Parity Lien Representative at the direction of an Act of Required Debtholders stating that (A)
any Series of Parity Lien Debt has become due and payable in full (whether at maturity, upon
acceleration or otherwise) or (B) the holders of Parity Liens securing one or more Series of Parity
Lien Debt have become entitled under any Parity Lien Document to and desire to enforce any or all
of the Parity Liens by reason of a default under such Parity Lien Documents, no payment of money
(or the equivalent of money) shall be made from the proceeds of Collateral by the Company or any
Guarantor to the Collateral Trustee (other than distributions to the Collateral Trustee for the
benefit of the holders of Parity Lien Obligations), any Junior Lien Representative or any holder of
Junior Lien Obligations (including, without limitation, payments and prepayments made for
application to Junior Lien Obligations).

     (d) All proceeds of Collateral received by the Collateral Trustee, any Junior Lien
Representative or any holder of Junior Lien Obligations in violation of Section 2.4(c) will be held
by such Person in trust for the account of the holders of Parity Lien Obligations and remitted to
any Parity Lien Representative upon demand by such Parity Lien Representative. The Junior Liens
will remain attached to and, subject to Section 2.3, enforceable against all proceeds so held or
remitted. All proceeds of Collateral received by the Collateral Trustee, any Junior Lien
Representative or any holder of Junior Lien Obligations not in violation of Section 2.4(c) will be
received by such Person free from the Parity Liens.

     SECTION 2.5 Waiver of Right of Marshalling.

          (a) Prior to the Discharge of Parity Lien Obligations, holders of Junior Lien Obligations,
each Junior Lien Representative and the Collateral Trustee may not assert or enforce any right of
marshalling accorded to a junior lienholder, as against the holders of Parity Lien Obligations and
the Parity Lien Representatives (in their capacity as senior or priority lienholders) with respect
to the Collateral.

          (b) Following the Discharge of Parity Lien Obligations, the holders of Junior Lien Obligations
and any Junior Lien Representative may assert their right under the UCC or otherwise to any
proceeds remaining following a sale or other disposition of Collateral by, or on behalf of, the
holders of Parity Lien Obligations.

     SECTION 2.6 Discretion in Enforcement of Parity Liens. 

          (a) In exercising rights and remedies with respect to the Collateral, the Parity Lien
Representatives (acting pursuant to an Act of Required Debtholders) may enforce (or refrain from
enforcing) or instruct the Collateral Trustee to enforce (or refrain from enforcing) the provisions
of the Parity Lien Documents and exercise (or refrain from exercising) or instruct the Collateral
Trustee to exercise (or refrain from exercising) remedies thereunder or any such rights and
remedies, all in such order and in such manner as the Required Parity Lien Debtholders may
determine, including:

     (1) the exercise or forbearance from exercise of all rights and remedies in respect of
the Collateral and/or the Parity Lien Obligations;

     (2) the enforcement or forbearance from enforcement of any Parity Lien in respect of
the Collateral;

     (3) the exercise or forbearance from exercise of rights and powers of a holder of
shares of stock included in the Senior Trust Estate to the extent provided in the Security
Documents;

     (4) the acceptance of the Collateral in full or partial satisfaction of the Parity Lien
Obligations; and

     (5) the exercise or forbearance from exercise of all rights and remedies of a secured
lender under the UCC or any similar law of any applicable jurisdiction or in equity.

     SECTION 2.7 Discretion in Enforcement of Parity Lien Obligations. Without in any way limiting the generality of Section 2.6, the holders of Parity Lien
Obligations and the Parity Lien Representatives may, or may cause the Collateral Trustee to, at any
time and from time to time, without the consent of the Collateral Trustee, holders of Junior Lien
Obligations or the Junior Lien Representatives, without notice to holders of Junior Lien
Obligations or the Junior Lien Representatives, without incurring responsibility to the Collateral
Trustee, holders of Junior Lien Obligations or the Junior Lien Representatives and without
impairing or releasing the subordination provided in this Agreement or the obligations hereunder of
the Collateral Trustee,
holders of Junior Lien Obligations or the Junior Lien Representatives, do any one or more of
the following:

Terremark — Collateral Trust Agreement

19

 

     (1) change the manner, place or terms of payment or extend the time of payment of, or
renew or alter, the Parity Lien Obligations, or otherwise amend or supplement in any manner
the Parity Lien Obligations, or any instrument evidencing the Parity Lien Obligations or any
agreement under which the Parity Lien Obligations are outstanding;

     (2) release any Person or entity liable in any manner for the collection of the Parity
Lien Obligations;

     (3) release the Parity Lien on any Collateral; and

     (4) exercise or refrain from exercising any rights against any Guarantor.

     SECTION 2.8 Insolvency or Liquidation Proceedings.

          (a) If in any Insolvency or Liquidation Proceeding and prior to the Discharge of Parity Lien
Obligations, the holders of Parity Lien Obligations by an Act of Required Debtholders consent to
any order:

     (1) for use of cash collateral;

     (2) approving a debtor-in-possession financing secured by a Lien that is senior to or
on a parity with all Parity Liens upon any property of the estate in such Insolvency or
Liquidation Proceeding;

     (3) granting any relief on account of Parity Lien Obligations as adequate protection
(or its equivalent) for the benefit of the holders of Parity Lien Obligations in the
Collateral; or

     (4) relating to a sale of assets of the Company or any Guarantor that provides, to the
extent the Collateral sold is to be free and clear of Liens, that all Parity Liens and
Junior Liens will attach to the proceeds of the sale;

then, the holders of Junior Lien Obligations and the Junior Lien Representatives will not oppose or
otherwise contest the entry of such order, provided, that the holders of Junior Lien
Obligations or a Junior Lien Representative may request the grant to the Collateral Trustee, for
the benefit of the holders of Junior Lien Obligations and the Junior Lien Representatives, of a
junior Lien upon any property on which a Lien is (or is to be) granted under such order to secure
the Parity Lien Obligations, co-extensive in all respects with, but subordinated (as set forth in
Section 2.3) to, such Lien and all Parity Liens on such property. The holders of Parity Lien
Obligations and the Parity Lien Representatives agree not to oppose or otherwise contest in any
respect any request made by the Junior Lien Representatives for a junior lien pursuant to the
proviso to the preceding sentence.

Terremark — Collateral Trust Agreement

20

 

          Notwithstanding the foregoing, both before and during an Insolvency or Liquidation Proceeding,
the holders of Junior Lien Obligations and the Junior Lien Representatives may take any actions and
exercise any and all rights that would be available to a holder of unsecured claims, including,
without limitation, the commencement of Insolvency or Liquidation Proceedings against the Company
or any Guarantor in accordance with applicable law; provided, that, no holder of Junior Lien
Obligations or Junior Lien Representative will be permitted to take any of the actions prohibited
under Section 2.4(b) or oppose or contest any order that it has agreed not to oppose or contest
under clauses (1) through (4) of the preceding paragraph.

          (b) Neither the holders of Junior Lien Obligations nor any Junior Lien Representative will
file or prosecute in any Insolvency or Liquidation Proceeding any motion for adequate protection
(or any comparable request for relief) based upon their interest in the Collateral under the Junior
Liens, except that:

     (1) they may freely seek and obtain relief granting a junior Lien co-extensive in all
respects with, but subordinated (as set forth in Section 2.3) to, all Liens granted in such
Insolvency or Liquidation Proceeding to, or for the benefit of, the holders of Parity Lien
Obligations; and

     (2) they may freely seek and obtain any relief upon a motion for adequate protection
(or any comparable relief), without any condition or restriction whatsoever, at any time
after the Discharge of Parity Lien Obligations.

     SECTION 2.9 Collateral Shared Equally and Ratably within Class. The parties to this Agreement agree that the payment and satisfaction of all of the Secured
Obligations within each Class will be secured Equally and Ratably by the Liens established in favor
of the Collateral Trustee for the benefit of the Secured Parties belonging to such Class. It is
understood and agreed that nothing in this Section 2.9 is intended to alter the priorities among
Secured Parties belonging to different Classes as provided in Section 2.3.

     SECTION 2.10 Separate Grants of Security and Separate Classification. Each Parity Lien Representative, for itself and on behalf of the holders of the applicable
Parity Lien Obligations, and each Junior Lien Representative, for itself and on behalf of the
holders of the applicable Junior Lien Obligations, acknowledges and agrees that:

     (a) the grants of Liens pursuant to the Parity Lien Documents and the Junior Lien Documents
constitute separate and distinct grants of Liens; and

     (b) because of, among other things, their differing rights in the Collateral, the Junior Lien
Obligations are fundamentally different from the Parity Lien Obligations and must be separately
classified in any plan of reorganization proposed or adopted in an Insolvency or Liquidation
Proceeding.

Terremark — Collateral Trust Agreement

21

 

     To further effectuate the intent of the parties as provided in the immediately preceding
sentence, if it is held that the claims of the holders of Parity Lien Obligations and the holders
of Junior Lien Obligations in respect of the Collateral constitute (in whole or in part) only one
secured claim (rather than separate classes of senior and junior secured claims), then each of the
parties hereto hereby acknowledges and agrees that, subject to Sections 2.3 and 3.4, all
distributions shall be made as if there were separate classes of senior and junior secured claims
against the Company and the Guarantors in respect of the Collateral (with the effect being that, to
the extent that the aggregate value of the Collateral is sufficient (for this purpose ignoring all
claims held by the holders of Junior Lien Obligations), the holders of Parity Lien Obligations
shall be entitled to receive, in addition to amounts distributed to them in respect of principal,
pre-petition interest and other claims, all amounts owing (or that would be owing if there were
such separate classes of senior and junior secured claims) in respect of post-petition interest,
including any additional interest payable pursuant to the Parity Lien Documents, arising from or
related to a default, which is disallowed as a claim in any Insolvency or Liquidation Proceeding)
before any distribution is made in respect of the claims held by the holders of Junior Lien
Obligations with respect to the Collateral, with the Collateral Trustee, for itself and on behalf
of each of the Junior Lien Representatives and each holder of Junior Lien Obligations, hereby
acknowledging and agreeing to turn over to the Parity Lien Representatives, for the Parity Lien
Representatives and on behalf of the holders of the applicable Parity Lien Obligations, Collateral
or proceeds of Collateral otherwise received or receivable by them to the extent necessary to
effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim
or recovery of the holders of Junior Lien Obligations.

  ARTICLE 3. OBLIGATIONS AND POWERS OF COLLATERAL TRUSTEE

     SECTION 3.1 Undertaking of the Collateral Trustee.

with the Security Documents;

its other interests, rights, powers and remedies;

     (5) following an Secured Debt Default remit as provided in Section 3.4 all cash

     (6) execute and deliver amendments to the Security Documents as from time to time
authorized pursuant to Section 7.1 accompanied by an Officers’ Certificate to the effect
that the amendment was permitted under Section 7.1;

     (7) release any Lien granted to it by any Security Document upon any Collateral if and
as required by Section 4.1; and

          (b) Each party to this Agreement acknowledges and consents to the undertaking of the
Collateral Trustee set forth in Section 3.1(a) and agrees to each of the other provisions of this
Agreement applicable to the Collateral Trustee.

          (c) Notwithstanding anything to the contrary contained in this Agreement, the Collateral
Trustee will not commence any exercise of remedies or any foreclosure actions or otherwise take any
action or proceeding against any of the Collateral (other than actions as necessary to prove,
protect or preserve the Liens securing the Secured Obligations) unless and until it shall have been
directed by written notice of an Act of Required Debtholders and then only in accordance with the
provisions of this Agreement.

     SECTION 3.2 Release or Subordination of Liens. The Collateral Trustee will not release or subordinate any Lien of the Collateral Trustee
or consent to the release or subordination of any Lien of the Collateral Trustee, except:

          (a) as directed by an Act of Required Debtholders accompanied by an Officers’ Certificate to
the effect that the release or subordination was permitted by each applicable Secured Debt
Document;

          (b) as required by Article 4;

          (c) as ordered pursuant to applicable law under a final and nonappealable order or judgment of
a court of competent jurisdiction; or

          (d) for the subordination of the Junior Trust Estate and the Junior Liens to the Senior Trust
Estate and the Parity Liens.

     SECTION 3.3 Enforcement of Liens . If the Collateral Trustee at any time receives written notice stating that any event has
occurred that constitutes a default under any Secured Debt Document entitling the Collateral
Trustee to foreclose upon, collect or otherwise enforce its Liens thereunder, the Collateral
Trustee will promptly deliver written notice thereof to each Secured Debt Representative.
Thereafter, the Collateral Trustee will await direction by an Act of Required Debtholders and will
act, or decline to act, as directed by an Act of Required Debtholders, in the exercise and
enforcement of the Collateral Trustee’s interests, rights, powers and remedies in respect of the
Collateral or under the Security Documents or applicable law and, following the initiation of such
exercise of remedies, the Collateral Trustee will act, or decline to act, with respect to the
manner of such exercise of remedies as directed by an Act of Required Debtholders. Unless it has
been directed to the contrary by an Act of Required Debtholders, the
Collateral Trustee in any event may (but will not be obligated to) take or refrain from taking
such action with respect to any default under any Secured Debt Document as it may deem advisable to
preserve and protect the value of the Collateral.

connection with any foreclosure, collection or other enforcement of Liens granted to the Collateral
Trustee in the Security Documents, the proceeds received by the Collateral Trustee from such
foreclosure, collection or other enforcement will be distributed by the Collateral Trustee in the
following order of application:

     FIRST, to the payment of all amounts payable under this Agreement on account of the

          (b) If any Junior Lien Representative or any holder of a Junior Lien Obligation collects or
receives any proceeds in respect of any foreclosure, collection or other enforcement to which it
was not entitled pursuant to the terms of Section 3.4(a), whether after the commencement of an
Insolvency or Liquidation Proceeding or otherwise, such Junior Lien Representative or such holder
of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to the Collateral
Trustee, to be applied in accordance with Section 3.4(a). Until so delivered, such proceeds will
be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case
may be, in trust for the benefit of the holders of the Parity Lien Obligations. This Section
3.4(b) will not apply to payments received by any holder of Junior Lien Obligations if such
payments are not proceeds of, or the result of a realization upon, Collateral.

          (c) This Section 3.4 is intended for the benefit of, and will be enforceable as a third party
beneficiary by, each present and future holder of Secured Obligations, each present and future
Secured Debt Representative and the Collateral Trustee as holder of Parity Liens and Junior Liens.

          (a) The Collateral Trustee is irrevocably authorized and empowered to enter into and perform
its obligations and protect, perfect, exercise and enforce its interest, rights, powers and
remedies under the Security Documents and applicable law and in equity and to act as set forth in
this Article 3 or as requested in any lawful directions given to it from time to time in respect of
any matter by an Act of Required Debtholders.

          (b) No Secured Debt Representative or holder of Secured Obligations will have any liability
whatsoever for any act or omission of the Collateral Trustee.

     SECTION 3.6 Documents and Communications. The Collateral Trustee will permit each Secured Debt Representative and each holder of
Secured Obligations upon reasonable written notice from time to time to inspect and copy, at the
cost and expense of the party requesting such copies, any and all Security Documents and other
documents, notices, certificates, instructions or communications received by the Collateral Trustee
in its capacity as such.

     SECTION 3.7 For Sole and Exclusive Benefit of Holders of Secured Obligations. The Collateral Trustee will accept, hold, administer and enforce all Liens on the

     SECTION 3.8 Additional Secured Debt.

          (a) The Collateral Trustee will, as trustee hereunder, perform its undertakings set forth in
Section 3.1(a) with respect to each holder of Secured Obligations of a Series of Secured Debt that
is issued or incurred after the date hereof that:

     (1) holds Secured Obligations that are identified as Parity Lien Debt or Junior Lien
Debt in accordance with the procedures set forth in Section 3.8(b);

     (2) signs, through its designated Secured Debt Representative identified pursuant to
Section 3.8(b), a Collateral Trust Joinder and delivers the same to the Collateral Trustee
and each other Secured Debt Representative at the time of incurrence of such Series of
Secured Debt; and

     (b) The Company will be permitted to designate as an additional holder of Secured Obligations
hereunder each Person who is, or who becomes, the registered holder of Junior Lien Debt or the
registered holder of Parity Lien Debt incurred by the Company or any Guarantor after the date of
this Agreement in accordance with the terms of all applicable Secured Debt Documents. The Company
may only effect such designation by delivering to the Collateral Trustee an Additional Secured Debt
Designation stating that:

     (1) the Company or such Guarantor intends to incur additional Secured Debt (“Additional
Secured Debt”) which will either be (i) Parity Lien Debt permitted by each applicable
Secured Debt Document to be secured by a Parity Lien Equally and Ratably with all previously
existing and future Parity Lien Debt or (ii) Junior Lien Debt permitted by each applicable
Secured Debt Document to be secured with a Junior Lien Equally and Ratably with all
previously existing and future Junior Lien Debt;

     (2) specifying the name and address of the Secured Debt Representative for such series
of Additional Secured Debt for purposes of Section 7.7.

     (3) the Company and each Guarantor has duly authorized, executed (if applicable) and
recorded (or caused to be recorded) in each appropriate governmental office all relevant
filings and recordations to ensure that the Additional Secured Debt is secured by the
Collateral in accordance with the Security Documents, including, without limitation, the
applicable Required Mortgage Amendment Deliverables (as defined in the Mortgage); and

     (4) the Company has caused a copy of the Additional Secured Debt Designation to be
delivered to each then existing Secured Debt Representative.

Although the Company shall be required to deliver a copy of each Additional Secured Debt
Designation and each Collateral Trust Joinder to each then existing Secured Debt Representative,
the failure to so deliver a copy of the Additional Secured Debt Designation and/or Collateral Trust
Joinder to any then existing Secured Debt Representative shall not affect the status of such

debt as Additional Secured Debt if the other requirements of this Section 3.8 are complied with.
Each of the Collateral Trustee and the other then existing Secured Debt Representative shall have
the right to request that the Company provide a copy of any legal opinion of counsel (which may be
provided by internal counsel to the Company) provided to the holders of Additional Secured Debt or
their Secured Debt Representatives as to the Additional Secured Debt being secured by a valid and
perfected security interest. Notwithstanding the foregoing, nothing in this Agreement will be
construed to allow the Company or any Guarantor to incur additional Indebtedness unless otherwise
permitted by the terms of all applicable Secured Debt Documents.

     The Security Documents creating or evidencing the Parity Liens and the Junior Liens and
Guarantees for the Parity Lien Obligations and the Junior Lien Obligations shall be in all material
respects the same forms of documents other than with respect to the first lien and the second lien
nature of the Obligations thereunder. So long as the Discharge of Parity Lien Obligations has not
occurred, whether or not any Insolvency or Liquidation Proceeding has been commenced by or against
the Company or any Guarantor, the parties hereto agree that the Company shall not, and shall not
permit any other Guarantor to grant or permit any additional Liens on any asset or property to
secure any Junior Lien Obligation unless it has granted or concurrently grants a Lien on such asset
or property to secure the Parity Lien Obligations.

definitions relating hereto, (B) such officer has made such examination or investigation as

Terremark — Collateral Trust Agreement

28

 

          (c) The Collateral Trustee hereby agrees that:

     (1) in the case of any release pursuant to clause (2) of Section 4.1(a), if the terms
of any such sale, transfer or other disposition require the payment of the purchase price to
be contemporaneous with the delivery of the applicable release, then, at the written request
of and at the expense of the Company or Guarantor, the Collateral Trustee will either (A) be
present at and deliver the release at the closing of such transaction or (B) deliver the
release under customary escrow arrangements that permit such contemporaneous payment and
delivery of the release; and

     (2) within one Business Day of the receipt by it of any Officer’s Certificate in

     (c) upon payment in full and discharge of all amounts of such Series of Secured Debt

     SECTION 5.4 Jurisdictional Limitations. The Collateral Trustee shall be under no
obligation or duty to take any action under this Agreement or any of the Parity Lien Documents or

Collateral Trustee as of the date of this Agreement
and, as directed by an Act of Required Debtholders (or as otherwise required under any
Security Document), the Collateral Trustee shall execute additional Security Documents delivered to
it after the date of this Agreement; provided, however, that such additional Security Documents do
not adversely affect the rights, privileges, benefits and immunities of the Collateral Trustee, as
determined by the Collateral Trustee in its sole discretion. The Collateral Trustee will not
otherwise be bound by, or be held obligated by, the provisions of any credit agreement, indenture
or other agreement governing Secured Debt (other than this Agreement and the other Security
Documents).

     SECTION 5.7 Solicitation of Instructions.

          (a) The Collateral Trustee may at any time solicit written confirmatory instructions, in the

may propose to take, in the performance of any of its obligations under this Agreement or the other
Security Documents.

          (b) No written direction given to the Collateral Trustee by an Act of Required Debtholders
that in the reasonable judgment of the Collateral Trustee imposes, purports to impose or might

forth in or arising under this Agreement and the other Security Documents will be binding upon the
Collateral Trustee unless the Collateral Trustee elects, at its sole option, to accept such
direction.

     SECTION 5.8 Quality of Instructions. Notwithstanding anything herein to the contrary,
in no event shall the Collateral Trustee have any obligation to inquire or investigate as to the
correctness, veracity, or content of any instruction received from the Trustee or any debtholder.

the holders of Secured Obligations for whom it acts,

Terremark — Collateral Trust Agreement

without being required to determine the authenticity thereof or the correctness of any fact
stated therein or the propriety or validity of service thereof. The Collateral Trustee may act in
reliance upon any instrument comporting with the provisions of this Agreement or any signature
reasonably believed by it to be genuine and may assume that any Person purporting to give notice or
receipt or advice or make any statement or execute any document in connection with the provisions
hereof or the other Security Documents has been duly authorized to do so. To the extent an
Officers’ Certificate or opinion of counsel is required or permitted under this Agreement to be
delivered to the Collateral Trustee in respect of any matter, the Collateral Trustee may rely
conclusively on an Officers’ Certificate or opinion of counsel as to such matter and such Officers’
Certificate or opinion of counsel shall be full warranty and protection to the Collateral Trustee
for any action taken, suffered or omitted by it under the provisions of this Agreement and the
other Security Documents.

     SECTION 5.12 Secured Debt Default. Except for its obligations under Section 3.3, the Collateral Trustee will not be required
to inquire as to the occurrence or absence of any Secured Debt Default and will not be affected by
or required to act upon any notice or knowledge as to the occurrence of any Secured Debt Default
unless and until it is directed by an Act of Required Debtholders.

it against any and all liability or expense which may be incurred by it by reason of taking or
continuing to take such action.

     SECTION 5.15 Rights of the Collateral Trustee. In the event there is any bona fide, good faith disagreement between the other parties to
this Agreement or any of the other Security Documents resulting in adverse claims being made in
connection with Collateral held by the Collateral Trustee, and the terms of this Agreement or any
of the other Security Documents do not unambiguously mandate the action the Collateral Trustee is
to take or not to take in connection therewith under the circumstances then existing, or the
Collateral Trustee is in doubt as to what action it is required to take or not to take hereunder or
under the other Security Documents, it will be entitled to refrain from taking any action (and will
incur no liability for doing so) until directed otherwise in writing by a request signed jointly by
the parties hereto entitled to give such direction or by order of a court of competent
jurisdiction.

     SECTION 5.16 Limitations on Duty of Collateral Trustee in Respect of Collateral.

          (a) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the
Collateral Trustee will have no duty as to any Collateral in its possession or control or in the
possession or control of any agent or bailee or any income thereon or as to preservation of rights
against prior parties or any other rights pertaining thereto and the Collateral Trustee will not be
responsible for filing any financing or continuation statements or recording any documents or
instruments in any public office at any time or times or otherwise perfecting or maintaining the
perfection of any Liens on the Collateral. The Collateral Trustee will be deemed to have exercised
reasonable care in the custody of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which it accords its own property, and the Collateral Trustee
will not be liable or responsible for any loss or diminution in the value of any of the Collateral
by reason of the act or omission of any carrier, forwarding agency or other agent or bailee
selected by the Collateral Trustee in good faith, except to the extent of the Collateral Trustee’s
gross negligence, bad faith or willful misconduct.

          (b) The Collateral Trustee will not be responsible for the existence, genuineness or value of
any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in
any of the Collateral, whether impaired by operation of law or by reason of any action or omission
to act on its part hereunder, except to the extent such action or omission constitutes negligence
or willful misconduct on the part of the Collateral Trustee, for the validity or sufficiency of the
Collateral or any agreement or assignment contained therein, for the validity of the title of the
Company or any Guarantor to the Collateral, for insuring the Collateral or for the payment of
taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the
Collateral.

     SECTION 5.17 Assumption of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein:

     (1) each of the parties thereto will remain liable under each of the Security Documents
(other than this Agreement) to the extent set forth therein to perform all of their
respective duties and obligations thereunder to the same extent as if this Agreement had not
been executed;

     (2) the exercise by the Collateral Trustee of any of its rights, remedies or powers
hereunder will not release such parties from any of their respective duties or obligations
under the other Security Documents; and

     (3) the Collateral Trustee will not be obligated to perform any of the obligations or
duties of any of the parties thereunder other than the Collateral Trustee.

     SECTION 5.18 No Liability for Clean Up of Hazardous Materials. In the event that the Collateral Trustee is required to acquire title to an asset for any
reason, or take any managerial action of any kind in regard thereto, in order to carry out any
fiduciary or trust obligation for the benefit of another, which in the Collateral Trustee’s sole
discretion may cause the Collateral Trustee to be considered an “owner or operator” under any
environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any
environmental liability or

Terremark — Collateral Trust Agreement

33

 

any liability under any other federal, state or local law, the Collateral Trustee reserves the
right, instead of taking such action, either to resign as Collateral Trustee or to arrange for the
transfer of the title or control of the asset to a court appointed receiver. The Collateral
Trustee will not be liable to any Person for any environmental liability or any environmental
claims or contribution actions under any federal, state or local law, rule or regulation by reason
of the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or
relating to any kind of discharge or release or threatened discharge or release of any hazardous
materials into the environment.

			
	ARTICLE 6.	 	RESIGNATION AND REMOVAL OF THE COLLATERAL TRUSTEE

the acceptance of such appointment by the successor Collateral Trustee:

          (a) the Collateral Trustee may resign at any time by giving not less than 60 days’ notice of
resignation to each Secured Debt Representative and the Company, provided that such notice period
may be waived by each Secured Debt Representative (acting pursuant to an Act of Required
Debtholders) and the Company; and

          (b) the Collateral Trustee may be removed at any time, with or without cause, by an Act of
Required Debtholders.

     SECTION 6.2 Appointment of Successor Collateral Trustee. Upon any such resignation or removal, a successor Collateral Trustee may be appointed by an
Act of Required Debtholders subject to the consent of the Company. If no successor Collateral
Trustee has been so appointed and accepted such appointment within 60 days after the predecessor
Collateral Trustee gave notice of resignation or was removed, the retiring Collateral Trustee may
(at the expense of the Company), at its option, appoint a successor Collateral Trustee, or petition
a court of competent jurisdiction for appointment of a successor Collateral Trustee, which must be
a bank or trust company:

     (1) authorized to exercise corporate trust powers;

     (2) having a combined capital and surplus of at least $150,000,000;

     (3) maintaining an office in New York, New York; and

the successor Collateral Trustee to transfer to the successor Collateral Trustee all Liens,
interests, rights, powers and remedies of the predecessor Collateral Trustee in respect of
the Security Documents or the Trust Estates.

Thereafter the predecessor Collateral Trustee will remain entitled to enforce the immunities
granted to it in Article 5 and the provisions of Sections 7.10 and 7.11.

     SECTION 6.4 Merger, Conversion or Consolidation of Collateral Trustee. Any Person into which the Collateral Trustee may be merged or converted or with which it
may be consolidated, or any Person resulting from any merger, conversion or consolidation to which
the Collateral Trustee shall be a party, or any Person succeeding to the business of the Collateral
Trustee shall be the successor of the Collateral Trustee pursuant to Section 6.3, provided that (i)
without the execution or filing of any paper with any party hereto or any further act on the part
of any of the parties hereto, except where an instrument of transfer or assignment is required by
law to effect such succession, anything herein to the contrary notwithstanding, such Person
satisfies the eligibility requirements specified in clauses (1) through (4) of Section 6.2 and (ii)
prior to any such merger, conversion or consolidation, the Collateral Trustee shall have notified
the Company, each Parity Lien Representative and each Junior Lien Representative thereof in
writing.

Document will be effective without the approval of the Collateral Trustee acting as directed by an

     (1) any amendment or supplement that has the effect solely of (i) adding or maintaining
Collateral, securing additional Secured Debt that was otherwise permitted by the terms of
the Secured Debt Documents to be secured by the Collateral or preserving, perfecting or
establishing the priority of the Liens thereon or the rights of the Collateral Trustee
therein; (ii) curing any ambiguity, defect or inconsistency; (iii) providing for the
assumption of the Company’s or any Guarantor’s obligations under any Security Document in
the case of a merger or consolidation or sale of all or substantially all of the Company’s
or such Guarantor’s assets, as applicable; or (iv) making any change that would provide any
additional rights or benefits to the Secured Parties or the
Collateral Trustee or that does not adversely affect the legal rights under any Secured

thereto and the Collateral Trustee;

35

 

     (2) no amendment or supplement that reduces, impairs or adversely affects the right of
any holder of Secured Obligations:

     (A) to vote its outstanding Secured Debt as to any matter described as subject
to an Act of Required Debtholders or direction by the Required Parity Lien
Debtholders or Required Junior Lien Debtholders (or amends the provisions of this
clause (2) or the definitions of “Act of Required Debtholders”, “Required Parity
Lien Debtholders” or “Required Junior Lien Debtholders”),

     (B) to share in the order of application described in Section 3.4 in the

or any Secured Debt Representative or adversely affects the rights of the Collateral Trustee
or any Secured Debt Representative, respectively, in its individual capacity as such will
become effective without the consent of the Collateral Trustee or such Secured Debt
Representative, respectively.

     (b) Notwithstanding Section 7.1(a) but subject to Sections 7.1(a)(2) and 7.1(a)(3):

     (1) any Security Document that secures Junior Lien Obligations (but not Parity Lien

acting as directed in writing by the Required Junior Lien Debtholders, unless such amendment
or supplement would not be permitted under the terms of this Agreement or the other Parity
Lien Documents; and

     (2) any amendment or waiver of, or any consent under, any provision of this Agreement
or any other Security Document that secures Parity Lien Obligations (except any such
amendment, waiver or consent that releases Collateral with respect to which any consent of
holders of Junior Lien Debt is required pursuant to this Agreement, which will be governed
by the provisions set forth above) will apply automatically to any comparable provision of
any comparable Junior Lien Document without the consent of or notice to any holder of Junior
Lien Obligations and without any action by the Company or any Guarantor or any holder of
notes or other Junior Lien Obligations.

Terremark — Collateral Trust Agreement

36

 

          (c) The Collateral Trustee will not enter into any amendment or supplement unless it has
received an Officers’ Certificate to the effect that such amendment or supplement will not result
in a breach of any provision or covenant contained in any of the Secured Debt Documents. Prior to
executing any amendment or supplement pursuant to this Section 7.1, the Collateral Trustee will be
entitled to receive an opinion of counsel of the Company (which may be provided by internal counsel
to the Company) to the effect that the execution of such document is authorized or permitted
hereunder, and with respect to amendments adding Collateral, an opinion of counsel of the Company
addressing customary perfection, and if such additional Collateral consists of equity interests of
any Person, priority matters with respect to such additional Collateral (subject to customary
qualifications and assumptions).

          (d) The holders of Junior Lien Obligations and the Junior Lien Representatives agree that each
Security Document that secures Junior Lien Obligations (but not also securing Parity Lien
Obligations) will include language substantially to the effect of the following:

     “Notwithstanding anything herein to the contrary, the lien and security interest granted to
the Collateral Trustee pursuant to this Agreement and the exercise of any right or remedy by such
Collateral Trustee hereunder are subject to the provisions of the Collateral Trust Agreement, dated
as of June 24, 2009, among the Company, the Guarantors from time to time party thereto, The Bank of
New York Mellon Trust Company, N.A., as Trustee under the Indenture (as defined therein) and U.S.
Bank National Association, as Collateral Trustee (as amended, supplemented, amended and restated or
otherwise modified and in effect from time to time, the “Collateral Trust Agreement”). In the
event of any conflict between the terms of the Collateral Trust Agreement and this Agreement, the
terms of the Collateral Trust Agreement will govern.”

; provided, however, that if the jurisdiction in which any such Junior Lien Document will be filed
prohibits the inclusion of the language above or would prevent a document containing such language
from being recorded, the Junior Lien Representatives and the Parity Lien Representatives agree,
prior to such Junior Lien Document being entered into, to negotiate in good faith replacement
language stating that the lien and security interest granted under such Junior Lien Document is
subject to the provisions of this Agreement.

     SECTION 7.2 Voting. In connection with any matter under this Agreement requiring a vote of holders of Secured
Debt, each Series of Secured Debt will cast its votes in accordance with the Secured Debt Documents
governing such Series of Secured Debt. The amount of Secured Debt to be voted by a Series of
Secured Debt will equal (1) the aggregate outstanding principal amount of Secured Debt held by such
Series of Secured Debt (including outstanding letters of credit whether or not then available or
drawn), plus (2) the aggregate unfunded commitments to extend credit which, when funded, would
constitute Indebtedness of such Series of Secured Debt. Following and in accordance with the
outcome of the applicable vote under its Secured Debt Documents, the Secured Debt Representative of
each Series of Secured Debt will vote the total amount of Secured Debt under that Series of Secured
Debt as a block in respect of any vote under this Agreement.

negotiable documents, tangible chattel paper, electronic chattel paper, certificated securities,

rights hereunder, and any attempted delegation or assignment of any such duties or rights will be
null and void. All obligations of the Company and the Guarantors hereunder will inure to the sole

          (a) The Company and the Guarantors jointly and severally agree to defend, indemnify, pay and
hold harmless the Collateral Trustee and its Affiliates and each and all of the directors,
officers, partners, trustees, employees, attorneys and agents, and (in each case) their respective
heirs, representatives, successors and assigns (each of the foregoing, an “Indemnitee”) from and
against any and all Indemnified Liabilities; provided, no Indemnitee will be entitled to
indemnification hereunder with respect to any Indemnified Liability to the extent such Indemnified

have resulted from the gross negligence or willful misconduct of such Indemnitee.

          (b) All amounts due under this Section 7.11 will be payable upon demand.

          (c) To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth

Indemnified Liabilities incurred by Indemnitees or any of them.

          (d) Neither the Company nor any Guarantor will ever assert any claim against any Indemnitee,

Document or any agreement or instrument or transaction contemplated hereby or relating in any
respect to any Indemnified Liability, and the Company and each of the Guarantors hereby forever
waives, releases and agrees not to sue upon any claim for any such lost profits or special,
indirect, consequential or (to the fullest extent lawful) punitive damages, whether or not accrued
and whether or not known or suspected to exist in its favor.

     SECTION 7.15 Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS

LAW).

     SECTION 7.16 Consent to Jurisdiction. All judicial proceedings brought against any party hereto arising out of or relating to
this Agreement or any of the other Security Documents may be brought in any state or federal court

irrevocably:

     (1) accepts generally and unconditionally the nonexclusive jurisdiction and venue of
such courts;

     (2) waives any defense of forum non conveniens;

     (3) agrees that service of all process in any such proceeding in any such court may be

manner permitted by law or to bring proceedings against any party in the courts of any other
jurisdiction.

     SECTION 7.17 Waiver of Jury Trial. Each party to this Agreement waives its rights to a jury trial of any claim or cause of
action based upon or arising under this Agreement or any of the other Security Documents or any
dealings between them relating to the subject matter of this Agreement or the intents and purposes
of the other Security Documents. The scope of this waiver is intended to be all-encompassing of
any and all disputes that may be filed in any court and that relate to the subject matter of this
Agreement and the other Security Documents, including contract claims, tort claims, breach of duty
claims and all other common law and statutory claims. Each party to this Agreement acknowledges
that this waiver is a material inducement to enter into a business relationship, that each party

Terremark — Collateral Trust Agreement

43

 

reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its
jury trial rights following consultation with legal counsel. This waiver is irrevocable, meaning
that it may not be modified either orally or in writing (other than by a mutual written waiver
specifically referring to this Section 7.17 and executed by each of the parties hereto), and this
waiver will apply to any subsequent amendments, renewals, supplements or modifications of or to
this Agreement or any of the other Security Documents or to any other documents or agreements
relating thereto. In the event of litigation, this Agreement may be filed as a written consent to
a trial by the court.

     SECTION 7.18 Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile or
electronic transmission), each of which when so executed and delivered will be deemed an original,
but all such counterparts together will constitute but one and the same instrument.

the parties hereto on the date hereof and receipt by each party of written notification of such
execution and written or telephonic authorization of delivery thereof

     SECTION 7.20 Additional Guarantors. The Company will cause each Subsidiary that becomes a Guarantor or is required by any
Secured Debt Document to become a party to this Agreement to become a party to this Agreement, for
all purposes of this Agreement, by causing such Subsidiary to execute and deliver to the Collateral
Trustee a Collateral Trust Joinder within 30 days of the event causing such Subsidiary to become a
Guarantor or to be required by a Secured Debt Document to become a party to this Agreement (as
applicable), whereupon such Subsidiary will be bound by the terms hereof to the same extent as if
it had executed and delivered this Agreement as of the date hereof. The Company shall promptly
provide each Secured Debt Representative with a copy of each Collateral Trust Joinder executed and
delivered pursuant to this Section 7.20; provided, however, that the failure to so deliver a copy
of the Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect
the inclusion of such Person as a Guarantor if the other requirements of this Section 7.20 are
complied with.

     SECTION 7.21 Continuing Nature of this Agreement. This Agreement, including the subordination provisions hereof, will be reinstated if at any
time any payment or distribution in respect of any of the Parity Lien Obligations is rescinded or
must otherwise be returned in an Insolvency or Liquidation Proceeding or otherwise by any holder of
Parity Lien Obligations or Parity Lien Representative or any representative of any such party
(whether by demand, settlement, litigation or otherwise). In the event that all or any part of a
payment or distribution made with respect to the Parity Lien Obligations is recovered from any
holder of Parity Lien Obligations or any Parity Lien Representative in an Insolvency or Liquidation
Proceeding or otherwise, such payment or distribution received by any holder of Junior Lien
Obligations or Junior Lien Representative with respect to the Junior Lien Obligations from the
proceeds of any Collateral at any time after the date of the payment or distribution that is so
recovered, whether pursuant to a right of subrogation or otherwise, that Junior Lien Representative
or that holder of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to
the Collateral Trustee, for the account of the holders of the Parity Lien Obligations, to be
applied in accordance
with Section 3.4. Until so delivered, such proceeds will be held by that Junior Lien
Representative or that holder of a Junior Lien Obligation, as the case may be, for the benefit of
the holders of the Parity Lien Obligations.

Liquidation Proceeding on the same basis as prior to the date of the commencement of any such case,
as provided in this Agreement.

     SECTION 7.23 Rights and Immunities of Secured Debt Representatives. The Trustee will be entitled to all of the rights, protections, immunities and indemnities
set forth in the Indenture and any future Secured Debt Representative will be entitled to all of

other agreement governing the applicable Secured Debt with respect to which such Person is acting
