above and to receive the cash dividends it is entitled to receive pursuant to subparagraph
(d) below.

shall hold the received Distributions as depositary of Pledgees and, upon Pledgees’ written
request, Pledgors shall deliver those Distributions to Pledgees.

Fifth. Covenants of Pledgors. So long as this Agreement is in effect, the Pledgors covenant
and agree that they (a) shall defend the right, title and interest of Pledgees in and to the
Pledged Equity Interests against the claims and demands of any Person other than Pledgees; (b)
shall not create, incur, assume, or permit to exist any Lien or security interest or option in
favor of, or any claim of any Person with respect to, any of the Pledged Equity Interests, whether
now held or hereafter subscribed, except for the first priority security interest created herein;
(c) shall not sell, transfer, assign, pledge, deliver, transfer in trust, grant, usufruct or
otherwise dispose of, or grant any option with respect to, any such Pledged Equity Interests or any
interest therein without the prior written consent of Pledgees; (d) shall execute and deliver to
Pledgees such documents in favor of Pledgees and do such things relating to the first priority
security interest created herein as Pledgees may reasonably request in order to protect and
maintain the first priority security interest and to protect and preserve the Pledged Equity
Interests, and pay all reasonable costs arising from or in connection therewith; (e) shall pay any
and all taxes,
assessments, and other charges of any nature which may be imposed, levied, or assessed against or
with respect to the Pledged Equity Interests or in connection with any Distributions (other than
taxes payable by Issuer in connection with such Distributions); and (f) shall cause Issuer to pay
taxes payable by Issuer in connection with such Distributions.

 

8

 

Sixth. Safekeeping of the Pledged Equity Interests. The obligations of Pledgees with
respect to the safekeeping and preservation of the Pledged Equity Interests shall be limited to the
obligations imposed by law. Any actions carried out by Pledgees for the safekeeping and
preservation of the Pledged Equity Interests shall be at the sole expense and risk of the Pledgors,
except for actions or omissions caused by the gross negligence, bad faith or willful misconduct of
Pledgees.

Seventh. Events of Default. If an Event of Default shall occur and be continuing (a) all
rights of the Pledgors to exercise or refrain from exercising any voting and other rights which
they would otherwise be entitled to exercise pursuant to Clause Fourth hereof shall cease and be
exercised thereafter by Pledgees; (b) Pledgees shall have the right to keep any and all
Distributions thereafter paid in respect of the Pledged Equity Interests and apply them to the
payment of the Secured Obligations; and (c) Pledgees are hereby expressly and irrevocably
authorized by the Pledgors to foreclose upon the first priority security interest created herein
pursuant to the provisions of Clause Eighth of this Agreement, and to exercise its rights in any
other manner as set forth in the Law.

Eighth. Foreclosure.

	(a)	 	The Pledgors hereby expressly and irrevocably agree that upon the occurrence of an Event of
Default, Pledgees may foreclose upon the first priority security interest created herein and
request the sale of the Pledged Equity Interests, if any, pursuant to Article 341 of the Law,
or exercise its rights in any other manner as set forth in the Law or this Agreement, in order
to seek payment of the Secured Obligations.

	(b)	 	The Pledgors shall take or shall cause Issuer to take any and all reasonable actions and/or
initiate any and all reasonable proceedings that may be necessary or convenient, in the
Pledgees’ sole discretion, to facilitate the execution and transfer of the Pledged Equity
Interests. The Pledgors further agree to do or cause to be done all such other reasonable acts
as may be necessary or convenient to expedite such sale or sales of all or any portion of the
Pledged Equity Interests, and to execute and deliver such documents and take such other action
as Pledgees deems necessary or advisable in order that any such sale may be in compliance with
applicable law.

 

9

 

	(c)	 	Due to the fact that the some Secured Obligations are monetary obligations denominated in
Dollars and payable outside of Mexico, in order to satisfy such Secured Obligations, any and
all amounts in Pesos that are received by Pledgees will be (i) exchanged by Pledgees in a
foreign exchange transaction into Dollars with a financial institution appointed by Pledgees,
and the currency so exchanged shall be distributed by Pledgees pursuant to the RVOP
Agreements; or (ii) in case such Pesos cannot be exchanged into Dollars as a result of
exchange rate controls or other governmental action, law or regulation, Pledgees will deliver
such Pesos to the Lender pursuant to the provisions of the RVOP Agreements.

Ninth.- Assignments. Unless the RVOP Agreements provides otherwise, the rights and
obligations arising from this Agreement may not be assigned or transferred by the Pledgors to any
third party without the prior written consent of Pledgees. Pledgees may assign, in whole or in
part, their rights hereunder, without requiring the consent of the Pledgors to perform such
assignment or transfer.

Tenth.- Amendments. Unless the RVOP Agreements provide otherwise, this Agreement may only
be amended or modified with the prior written consent of the Pledgors and Pledgees, subject to any
consent required in accordance with the RVOP Agreements.

Eleventh.- Notices. All notices to be delivered by the parties hereto shall be made in

C L A U S E S

FIRST. Assignment. Assignor, upon the occurrence of a default under any of the RVOP
Agreements (an “Event of Default”), by means of this Agreement irrevocably assigns and
transfers to the Assignees the Tergas Rights until the Secured Obligations under the RVOP
Agreements have been paid in satisfaction of the Assignees. The Assignor and the Assignees agree
(i) that the Tergas Rights shall not be modified without the prior written consent of Assignees;
and (ii) upon Assignees’ request and during the term of this Agreement, the Assignor shall carry
out any necessary act to guarantee that the Tergas Rights would not be modified or affected.

Assignor hereby agrees to grant an irrevocable power of attorney in favor of Assignees as the
exclusive authorized party to exercise the Stock Powers upon an Event of Default. In addition,
Assignor agrees that, upon an Event of the Default, all of its rights under such Stock Powers shall
be waived in favor of Assignees.

The assignment of the Tergas Rights shall not constitute payment, release or novation of the
obligations of RVOP under RVOP Agreements, unless such obligations are effectively being paid with
the proceeds of the sale of the Tergas Rights to a third party. The Assignees shall not assume any
obligations of the Assignor related to the Tergas Rights. Such obligations shall remain with the
Assignor, who shall comply with such in its totality. The Assignor does not have or retain any
rights to challenge the assignment of the Tergas Rights.

SECOND. Obligations. The Assignor, in addition to comply with any other obligations under
this Agreement or applicable law, shall:

(a) Give notices to the applicable parties and comply with the applicable requirements and
formalities in order to make effective such assignment of Tergas Rights, including notification
through Notary Public to Messrs. José Vicente Soriano García and Dennis Michael Sánchez, partners
of Tergas, of the assignment referred to herein.

(b) Carry out all the necessary or convenient acts to maintain the Tergas Rights and the rights of
the Assignees under this Agreement.

(c) Unless otherwise provided in this Agreement, not sell, pledge, assign, transfer, sell, lien or
in any other way convey the Tergas Rights, or accept a lien on the Tergas Rights by any person
other than the Assignees.
