referred to in the Concessions.

 

Such training shall be carried out in the
airport facilities where the above mentioned employees work or, as the case may be,
in the facilities of the Key Partners if it is so agreed upon by the Strategic
Partner.

 

(xii) Master Development Program:
Every 5 (five) years, the Airport Group must file with the SCT, for each
Assigned Airport, the reviews corresponding to its original Master Development
Program under article 38 of the Airports Law; therefore, the Strategic
Partner binds itself to provide such Technical Assistance as may be
necessary and to provide such training as may be required of 

 

11

 

the personnel of the Service Company for the preparation of such Master
Development Program. In order to prepare the above mentioned Master Program,
the Strategic Partner shall provide such Technical Information and financial,
feasibility and economic research as may be necessary.

 

(xiii) Public Offer: The Strategic

conclude such Public Offer as provided for in Section 2.3 of the
Participation Agreement.

 

(xiv) Assets and Insurance: The
Strategic Partner shall provide such Assistance and Technical Information as may be
required in connection with the administration of the properties, assets given
through the concession and expansion, improvement and remodelation projects of

contracting of insurance and the performance of audits and review of the
Administration of the Assigned Airports; and

 

(xv) Administrative Services Rendering
Agreement: The Strategic Partner states that it is aware of the terms of
the Administrative Services Rendering Agreement executed by the Service Company
with each of the Concession Companies for the administration thereof. The
Strategic Partner binds itself to render such Technical Advisory services as may be

such Administrative Services Rendering Agreement, upon request of the Airport
group through the Auditing Committee Delegate.

 

2.2.1.3 Excluded Services. The
Strategic Partner, the Partners of the Strategic Partner and the Related
Persons of both, agree to be subject to the following rules of
participation in the rendering of the following Services in the Assigned
Airports:

 

(i) Airport Services. They may not
participate in the rendering of Airport Services;

 

(ii) Complementary Services. They
may participate but they may not, in any case, compete with the
Holding Company or the Concession Companies in the rendering of such
Complementary Services;

 

(iii) Commercial Services. They may participate
through bidding, but they may in no event render Commercial Services in
the same line of business as the Holding Company or the Concession Companies in
a determined Assigned Airport; and

 

(iv) Construction and Supply. The
Strategic Partners or the Partners of the Strategic Partner may only
participate in activities of construction or supply in the Assigned Airports
whenever the respective agreements are awarded through a bidding process where
at least 3 (three) contractors participate (the “Third Parties”) in addition to
the Strategic Partner or any of the Partners of the Strategic Partner or
Related Persons thereto, as the case may be. In such case, the Auditing
Committee Delegate shall carry out the supervision and audit of the works
performed for that purpose through an independent work supervising company of
international recognition. In the event that in the bid by the Strategic
Partners or the Partners of the Strategic Partner, as the case may be, is
equal as to price, quality and opportunity, the agreement shall be awarded to a
Third 

 

12

 

Party. The Acquisitions and Agreements Committee shall set forth the
standards to which the bidding processes shall be subject.

 

2.3                                 Rendering of
Technical Assistance Services. The Strategic Partner and the Key Partners
shall carry out such acts that may be necessary in order for the
Administration of the Assigned Airports to comply, within a five-year period
commencing September 14, 2000, with the quality, safety, opportunity and
price standards set forth in each of the Concessions, consequently: 

 

2.3.1 Technical Assistance in the
Facilities of the Assigned Airports: The Strategic Partner and/or the Key
Partners shall assign qualified persons to render those services referred to in
Section 2.2.1.2 above, as requested by the Airport Group, through
the Auditing Committee Delegate, at the airport facilities of the Assigned
Airports as designated by the Service Company for the purpose of rendering any
Technical Assistance required under this Agreement. The number of the available
personnel and the characteristics and responsibilities thereof shall be
determined by mutual agreement in each case by the parties, and in failure to
reach such agreement, the Strategic Partner shall freely determine it and shall
be held responsible for any event or accident originating from the Administration
of the Assigned Airports, whenever such events or accidents arise from defaults
of the personnel engaged in the requested Technical Assistance.

 

2.3.2 Visits to the Facilities of the
Strategic Partner and of the Key Partners. In addition to the training
obligations set forth in Section 2.2.1.2 above, the Airport Group
shall be entitled to have, at its cost, any of its officers visit and review,
at least once a year, the airport facilities of the Key Partners where the
Airport Services are rendered by such Key Partners for the purpose of receiving
training. Such visits shall be for such period and at such time as agreed upon
in each case by the Airport Group and the Strategic Partner.

 

2.4                                 Technical
Information and Technical Knowledge. As soon as possible as from the date
on which the Strategic Partner receives from the Federal Government the second
Shares Package upon the terms of Section 2.5 of the Stock Purchase
Agreement, according to the working program that the Strategic Partner and the
Airport Group may agree upon for that purpose through the Auditing
Committee Delegate, the Strategic Partner, by itself or through the Key
Partners, shall provide to the Airport Group all the Technical Information and
any Technical Knowledge that may be necessary for the operation of the
Assigned Airports. For that purpose, the Strategic Partner shall deliver to the
Service Company, after the execution of a confidentiality agreement with the
Airport Group, copies of any drawings or industrial designs, descriptions,
operation manuals, quality control manuals and any other documents that
evidence Technical Information and Technical Knowledge. Likewise, the Strategic
Partner and/or the Partners of the Strategic Partner bind themselves to update
such information as soon as the same is amended or improved.

 

2.5                                 Request for the
Rendering of Included Consultancy Services. The Strategic Partner shall be
bound to render the Included Consultancy Services without the Airport Group
requiring the same. Notwithstanding the above, the Airport Group, through the
Auditing Committee Delegate, may request from the Strategic Partner the
rendering of any specific services contemplated in Section 2.2.1.2
by sending to the Strategic Partner a service request (the “Included Services
Request”), specifying in reasonable detail the nature and amount of the
required Included Consultancy Services (the “Required Included Services”) and
the time and place in which the corresponding Assigned Airport requires the
Included Consultancy Services. Additionally, in the event that the Strategic
Partner does not render any of the services referred to in Section 2.2.1.2
above, the Airport Group, through the Auditing Committee Delegate, may send
an Included 

 

13

 

Services Request, so that the Strategic Partner renders them as
indicated in such Included Services Request.

 

2.5.1 Rendering of the Included
Consultancy Services. The Strategic Partner must provide the Included
Consultancy Services upon such terms and conditions as specified in the
Included Services Request presented pursuant to this Agreement, therefore,
within 5 (five) business days following the date on which the Strategic Partner
receives an Included Services Request by the Airport Group through the Auditing
Committee Delegate, the Strategic Partner must send a notice to such Service
Company (the “Notice of Rendering of Included Services”) that specifies that
the Strategic Partner binds itself to render the Required Included Services
pursuant to the Included Services Request.

 

2.6 Additional Services. If any of the
Assigned Airports requires Consultancy Services which are not identical to or
substitutable with any of the Included Consultancy Services (the “Additional
Services”), the Acquisitions and Agreements Committee shall call both the
Strategic Partner and third parties to a bidding process for the rendering of
the Additional Services, for which purpose it must specify in reasonable
detail, the nature and amount of the required Additional Services, and the time
and place at which the corresponding Assigned Airport requires the Additional
Services.

 

The Acquisitions and Agreements Committee
shall award the rendering of the Additional Services to whomever offers the
best price, quality and timing conditions for the Airport Group.

 

The participation of the Strategic Partner,
the Key Partners and the Related Persons of both in the rendering of services
other than the Services in the Assigned Airports, and the contracting of works
and acquisitions in favor of the Concession Companies shall at all times be
subject to a bidding process for the respective contract, upon the terms set
forth by the Acquisitions and Agreements Committee. 

 

2.7                                 Determination of
the Services as Consultancy Services. In the event that there is
uncertainty in connection with the fact that any service is of identical or
substitutable nature with respect to any of the Consultancy Services, such
uncertainty shall be resolved by determination of an expert in the matter
appointed by the General Bureau of Civil Aeronautics of SCT.

 

2.8                                 Emergency Services.
In the event that any emergency arises in any of the Assigned Airports, the
Auditing Committee Delegate may request from the Strategic Partner the
rendering of any of the Consultancy Services or of Additional Services, in a
term of less than 15 (fifteen) calendar days (the “Emergency Services”), which
term may be extended in situations calling for the same. In all events,
the cost of such Emergency Services shall be set forth by mutual agreement
between the parties, and the previous bidding process referred to in Section 2.6
above shall not be required.

 

2.9                                 Reports. The
Strategic Partner agrees to provide to the Airport Group, through the Service
Company, a monthly report in connection with the rendering of the Consultancy
Services.

 

2.10                           In the rendering of the
services referred to in this Agreement each Airport shall seek to comply every
year with the operation parameters set forth in the Concessions as to the
number of performed operations, number of passengers and number of commercial
premises.

13.                               Resolution
of Controversies.

 

13.1                           Arbitration Rules.
For the interpretation of this Agreement and for the resolution of any
controversy hereunder, the Parties expressly and irrevocably submit themselves
to the 

 

23

 

arbitration proceeding governed by the arbitration rules (the “Arbitration
Rules”) of the International Chamber of Commerce, Mexican Chapter (“ICC”);
therefore, any controversy that may arise from, or in connection with,
this Agreement and any alleged default, termination or validity thereof (“Controversy”),
must, upon written request by one party, be delivered to the other parties (an “Arbitration
Request”), and be definitively resolved by arbitration conducted pursuant to
the Arbitration Rules of ICC except for the special rules set forth
in this Section 13. which, as the case may be, amend the
Arbitration Rules.

 

13.2 Arbitration Proceeding. The
arbitration proceeding shall be conducted, and the award shall be issued in
Mexico City, Federal District, United Mexican States, in the Spanish language.
The arbitration proceeding shall be conducted before three neutral arbitrators,
in accordance with the provisions hereinbelow contained. The Strategic Partner
and the Partners of the Strategic Partner shall appoint an arbitrator by mutual
agreement and the Airport Group shall appoint another one within 15 (fifteen)
days following the date on which an Arbitration Request is made, provided that
all the arbitrators shall be of a different nationality from that of the
Airport Group, the Strategic Partner and the Partners of the Strategic Partner.
The two appointed arbitrators shall jointly appoint by mutual agreement the
third arbitrator within a term not to exceed 15 (fifteen) days following the
appointment of the last of the first two arbitrators. The arbitrators shall
appoint, from among themselves, the arbitrator who shall act as chairman of the
arbitration court, within 5 (five) days following the date of the last of their
appointments. If any designation of the arbitrators is not made within the
terms herein set forth, ICC shall make such designation upon request by any
party. The arbitrators must be capable of reading, writing and fluently
speaking both English and Spanish, and must be experts in the matter in
question. Hearings shall be carried out no later than within 20 (twenty)
business days, and the award must be issued no later than within 60 (sixty)
business days, following the appointment of the third arbitrator.

 

13.3 Specific Compliance. In any
arbitration proceeding under this Agreement, the parties shall be authorized to
request a competent judge to order specific compliance with any obligation
under this Agreement, pursuant to article 1425 of the Code of Commerce,
any preventive measures.

 

13.4 Applicable Legislation and
Enforcement of Awards. The arbitrators shall decide the Controversy
pursuant to the substantive laws of the United Mexican States. In the event
that the mandatory enforcement of this award is required in a jurisdiction
other than the United Mexican States, the arbitration agreement and any award
hereunder, shall be ruled by the Convention of the United Nations of 1958
concerning the Procedure and Enforcement of Foreign Awards. The written
decision of the arbitrators, signed by a majority thereof, shall be final and
mandatory for the parties. Upon the receipt of such award, each party must
immediately (i) adopt such action, (ii) make such changes in the
conduct of its business or (iii) make such payments or repayments,
required by the arbitration decision, as the case may be. The award may be
reviewed and enforced in any court of competent jurisdiction. Such review shall
verify the compliance of the award with the formalities required by the
applicable legislation.

 

13.5 Allocation of Costs and Currency of
the Award. The party against which an award is issued pursuant to this Section 13.,
must pay all expenses and costs accrued by reason of the arbitration proceeding
in question, including the expenses and costs corresponding to the arbitrators
and ICC. Except for that set forth in the immediately preceding sentence, each
of the parties must pay all the expenses and costs incurred by such party in
connection with the arbitration proceeding other than those mentioned above.
Any monetary award must be made in dollars, lawful currency of the United 

 

24

 

States of America and may be paid in such currency or in lawful
currency of the United Mexican States at the exchange rate in effect on the
date of payment at the election of the debtor, free from any tax or other
deduction, and must include interest as from the date of any default or other
breach of this Agreement, as of the date on which the award is paid, with a
fair interest rate determined by the arbitrators.

 

13.6 Access to Documents. The non-confidential
books and documents of each party in an arbitration proceeding, as long as they
are related to matters submitted to arbitration, shall be available for
examination by the arbitrators and the other parties during such proceeding
prior to the applicable hearing.

 

13.7 Successors, Assignees, etc. The
arbitration agreement referred to in this Section 13. shall be
mandatory for the successors, assignees and any trustee, liquidator or receiver
of each party.

IN VIRTUE
OF THE FOREGOING, of the mutual agreements and conditions
contained in this Agreement, the Participation Agreement and the Transaction
Documents, and for the purpose of being legally bound in the terms thereof, the
Issuing Company and the Strategic Partner agree to the following

 

CLAUSES

 

1.             Purpose.

 

1.1           The
Issuing Company, with the approval of its shareholders granted in the
Extraordinary Shareholders’ Meeting, grants in favor of the Strategic Partner
the right (hereinafter the “Option”) to carry out the subscription and payment
of the Optional Shares which shall belong to Series “B” and shall represent at
all times 3% (three percent) of the capital stock of the Issuing Company (the
“Guaranteed Proportion”) (calculated on the number of outstanding shares plus
the issued shares, pending of subscription and payment and maintained in the
treasury of the Issuing Company), and which must be exercised upon the terms of
Section 2. below. Likewise, the Strategic Partner accepts the Option
granted in its favor by the Issuing Company.

 

1.2           The
exercise of the Option referred to in this Agreement is subject to the
Strategic Partner, the Partners of the Strategic Partner and their Related
Persons do not fail to comply with the provisions of Article 29 of the Airports
Law and its regulations.

 

2.             Exercise.

 

2.1           The
Strategic Partner or any other registered Holders may exercise the Option only
with respect to each Portion of Optional Shares, from each corresponding
Exercise Period, in order to acquire the corresponding Portion of Shares.

 

2.2           In
order to exercise the Option, the Strategic Partner or the registered Holders
thereof must notify to the Issuing Company their intention to exercise the
Option, and to subscribe and pay for the corresponding Portion of Optional
Shares within the corresponding Exercise Period, by submitting an Exercise
Notice in the form contained in Exhibit “1” of this Agreement.

 

2.3           Once
the Option has been exercised by the Strategic Partner or the registered
Holder, as the case may be, they shall assume an unconditional payment
obligation in favor of the Issuing Company with respect to the Subscription
Price of the Optional Shares, payable no later than at 12:00 o’clock, Mexico
City time, on the sixtieth business day following the Exercise Date.

 

2.4           In
the event that during any Exercise Period the Strategic Partner or any Option
Holder partially exercises or fails to exercise its right to acquire the
Portion of Optional Shares corresponding to such Exercise Period, the Option
corresponding to the non-exercised Portion of Optional Shares, or the entire
Option, shall be forfeited, as the case may be, without any liability for the
Issuing Company.

 

2.5           Neither
the Strategic Partner nor any Option Holder may exercise the Option if on the
Exercise Date, the Strategic Partner or the Option Holder contravene the
provisions of article six of the By-laws of the Holding Company, or if an event
of default under the Technical Assistance Agreement has occurred and such
default has been declared as such by any of the parties thereto.

 

4

 

2.6           The
Strategic Partner or, as the case may be, the Option Holder may, in the event
that (i) any shareholder acquires an individual participation equivalent to or
in excess of 35% (thirty-five percent) of the capital stock of the Issuing
Company, prior amendment to the corporate by-laws thereof for such purpose; or
(ii) the shareholders’ meeting resolves to approve a merger involving a
dilution of its shareholders in a percentage exceeding 35% (thirty-five
percent) of its total participation prior to the merger, fully exercise the
Option in advance, provided that it notifies the same to the Issuing Company
within 30 (thirty) days following (1) the date of the general shareholders
meeting resolving such amendment to the by-laws; or (2) the date of the general
extraordinary shareholders’ meeting approving the merger, as the case may be.

 

2.7           In
the event that during a period of 30 (thirty) consecutive days the market price
per share representing the capital stock of the Issuing Company is equivalent
to or in excess of $0.1536 U.S. Dollars (0.1536 Dollars, lawful currency of the
United States of America), that is, twice the price mentioned in Section 3.1
below, the Strategic Partner or, as the case may be, the Option Holder, may
exercise in advance the Option provided for in this Agreement, within the 60
(sixty) business days following the notice sent by the Issuing Company for that
purpose and, therefore, subscribe for and pay all the Optional Shares then
pending subscription and payment, at the price set forth in Section 3.1
below, subsequently terminating this Agreement. In the event that the Strategic
Partner or the Option Holder fails to exercise the same under this Section,
this Agreement shall be terminated without liability for the Issuing Company,
and such Option shall be forfeited in the future.

 

2.8           Release
of Optional Shares. Once the Option has been exercised by the Strategic
Partner or any other Holder and the subscription Price of the Optional Shares
has been paid for under Section 3.4 below, the Issuing Company shall
release the Optional Shares kept in its treasury which may have been acquired
in the exercise of the Option and shall deliver the certificates representing
them to the Strategic Partner or to the corresponding Holder, as the case may
be.

 

Notwithstanding the
foregoing, the Strategic Partner hereby undertakes the obligation to
irrevocably contribute to the Trust any Optional Shares that it may acquire at
any time by reason of the exercise of the Option subject matter of this
Agreement, in order for the same to be part of the trust estate and be subject
to the terms and conditions of the Trust Agreement.

 

3.             Price.

 

3.1           The
subscription price of the Optional Shares upon each exercise of the Option
shall be equal to $0.0768 U.S. Dollars (0.0768 Dollars, lawful currency of the
United States of America) per share, plus annual interest equivalent to 5%
(five percent) as from the date of execution of this Agreement until the Option
Exercise Date, in the understanding that the Subscription Price of the Optional
Shares shall be paid in Mexican currency at the exchange rate in force
published by Banco de México in the Official Gazette of the Federation the day
prior to the payment date.

 

3.2           In
the event that during the term of the Option referred to in this Agreement, the
Issuing Company pays to its shareholders dividends in cash or in shares, the
resulting price per share shall be reduced by the proportion of such dividends
in cash or in shares that would have corresponded to each Optional Share and
the interest referred to in Section 3.1 above shall be calculated based
on this result.

 

3.3           In
the event that the number of shares representing the capital stock of the
Issuing Company is modified without there being an increase or reduction in the
capital stock thereof, as in the case of splits, the Subscription Price of the
Optional Shares shall be automatically modified, in order for the subscription
value set forth in Section 3.1 to be modified in proportion to the
modification in the number of Optional Shares.

 

5

 

3.4           The
payment of the Subscription Price of the Optional Shares for which the Option
has been exercised must be made by the Strategic Partner or, as the case may
be, by the registered Holder which may have exercised it, not later than 60
(sixty) business days following the Date of Exercise of the Option, in
immediately available funds in favor of the Issuing Company in the account that
it notifies in writing prior to the payment.

 

4.             Obligations
of the Issuing Company.

 

4.1           As
from the date of this Agreement and until the final exercise of the Option, the
Issuing Company shall keep in its treasury sufficient shares representing at
all times the Guaranteed Portion reduced by the percentage of the Option with
respect to which the Option has been exercised in each Exercise Period.
Therefore, in the event that the shareholders of the Issuing Company approve
any increase in the capital stock of the Issuing Company before the last
Exercise Period of the Option, the shares necessary to keep the corresponding
Guaranteed Proportion shall be issued, and shall be kept in the treasury of the
Issuing Company as treasury shares, until the Holder exercises the
corresponding part of the Option. Such new shares in treasury shall be
considered as Optional Shares.

 

4.2           In
the event of any reductions in the capital stock of the Issuing Company, the
same shall be reduced pursuant to the instructions of the shareholders’ meeting
resolving such reduction, but at all times, before any Exercise Period of the
Option, shares representing the corresponding Guaranteed Proportion shall be
kept in the treasury of the Issuing Company. Consequently, when such reduction
of the capital stock of the Issuing Company is resolved, shares sufficient to
reach the corresponding Guaranteed Proportion, considering the Optional Shares
acquired in previous exercises of the Option, shall be cancelled.

 

4.3           In
the event that as from the execution hereof and until the final exercise of the
Option, the Issuing Company pays a stock dividend to its shareholders, the
Issuing Company shall issue the number of shares in treasury needed to maintain
the Guaranteed Proportion.

 

4.4           In
the event of any reduction in the par value, if any, of the Shares of the
Issuing Company, the par value, if any, of the Optional shares pending
subscription and payment shall be automatically reduced, without adjustment to
the Subscription Price of the Optional Shares.

 

4.5           In
the event that the number of shares representing the capital stock of the
Issuing Company is modified without an increase or reduction in the capital
stock of the Issuing Company, as in the case of splits, the number of Shares of
the Portions of Shares with respect to which the exercise of the Option is
pending, shall be automatically modified, and the provisions of Section 3.3
shall be applied.

 

4.6           In
any event, as from the first exercise of the Option, the Issuing Company shall
keep in its treasury, with respect to the Optional Shares, shares representing
3% (three percent) of its capital stock, considering the issued shares, pending
of subscription and payment and maintained in the treasury of the Issuing
Company, reduced in the percentage with respect to which the Strategic Partner
or any Holder thereof may have exercised the Option in each Exercise Period.
The Issuing Company shall inform periodically the Strategic Partner or, as the
case may be, the registered Holders, of the number of Optional Shares kept in
its treasury, as well as the percentage that the same represent in the capital
stock of the Issuing Company.

 

4.7           In
the event that the shareholders of the Issuing Company agree to place the
shares representing its capital stock among the public, a notice in writing
shall be sent to the Strategic Partner or, as the case may be, to the
registered Holders, with respect to this intention to quote the shares of the
Issuing 

 

6

 

Company in the securities
market, at least 15 (fifteen) calendar days prior to the date on which it is
foreseen that the quotation in the respective stock will commence.

 

4.8           The
Issuing Company must deliver to the Strategic Partner or, as the case may be,
to the registered Holders pursuant to Section 6. below, during the first
four months of each year, one copy of its financial statements and annual
report which may have been submitted to the shareholders for the approval
thereof by the general annual ordinary shareholders’ meeting.

 

4.9           The
Issuing Company agrees that during the entire term of this Agreement, not more
than 49% (forty-nine percent) of the capital stock of any of the Concession
Companies shall be transferred, nor shall it allow them to assign the
Concessions they have to operate the Assigned Airports. In all events, the
Issuing Company must comply with the applicable provisions included in the
By-laws of the Holding Company.

 

4.10         The
obligations of the shareholders of the Issuing Company provided for in this
Agreement must be assumed by any companies that succeed it by reason of
transfer of shares, mergers, consolidations, reorganizations or by any other
cause.

 

5.             Transfer
of the Option.

 

5.1           As
from the date of execution of this Agreement and until the First Exercise
Period, the Strategic Partner may dispose of, assign or otherwise transfer, the
Option to acquire the corresponding Portion of Optional Shares, hereby granted
by the Issuing Company, in favor of any of the Partners of the Strategic
Partner or Related Persons thereof.

 

5.2           As
from the First Exercise Period, the Strategic Partner or any Holder may dispose
of, assign or otherwise transfer the Option hereby granted by the Issuing
Company, in favor of an individual or legal entity satisfying the requirements
set forth in the Airport Law to be a shareholder of the Issuing Company (each
of them, a “Holder”) and who is able to acquire the Optional Shares under the
By-laws of the Holding Company. Any transfer of the Option against the
provisions of the Airport Law or this Agreement shall be null and shall have no
legal effect whatsoever.

 

5.3           The
part of the Option to be exercised during a specific Exercise Period may only
be transferred in favor of a single person and therefore, such part of the
Option may not be divided.

 

6.             Registry
of Holders.

 

6.1           The
Issuing Company must keep a registry of the Option Holders, which shall
indicate the name and domicile of each Holder, as well as the percentage of
shares of the Issuing Company representing the Option held by each of them and
the Exercise Period during which these options may be exercised.

 

6.2           For
purposes of the foregoing, the Strategic Partner or any Holder, as the case may
be, must provide the Issuing Company, no later than 10 (ten) days following the
date on which the Option held is transferred, the information referred to in Section
6.1 above.

 

6.3           The
Issuing Company shall not recognize as Holder any person in favor of which the
Option is transferred in violation of the provisions of Sections 5.1 and 5.2
and, therefore, shall not register such person as a Holder in terms of this
Section.

 

7

 

7.             Termination
of the Option.

 

7.1           The
Option held at any time by the Strategic Partner or any Holders who are Related
Persons of the Strategic Partner shall be immediately terminated without prior
notice being required, in the event that the Strategic Partner fails to comply
with any of its obligations under this Agreement or any of the Transaction
Documents, and such default is declared an Event of Default under the
Participation Agreement. The foregoing shall not be applicable in the event
that the Holders are not Related Persons of the Strategic Partner.

 

7.2           Notwithstanding
the foregoing, the Option shall be partially terminated in each exercise
thereof and totally terminated whenever all the Optional Shares have been
acquired.

 

7.3           This
Agreement shall be effective until the Option is terminated under this
Agreement.

 

8.             Amendments
and Waivers.

of Controversies.

 

10.1         Arbitration
Rules. For the construction of this Agreement and for the resolution of any
controversy that may arise therefrom, the Parties expressly and irrevocably
submit themselves to the arbitration proceeding regulated by the arbitration
rules (the “Arbitration Rules”) of the International Chamber of Commerce,
Mexican chapter (“ICC”); therefore, any controversy that may arise from, or in
connection with this Agreement and the alleged default, termination or validity
thereof (“Controversy”), must, upon written request of one party delivered to
the other parties (an “Arbitration Request”), be definitively resolved by
arbitration, substantiated under the Arbitration Rules of the ICC, except for
any special rules established in this Section 10., which may modify the
Arbitration Rules.

10.2         Arbitration
Proceeding. The arbitration proceeding shall be carried out, and the award
shall be issued in Mexico City, Federal District, United Mexican States, in the
Spanish language. The arbitration proceeding shall be conducted before three
neutral arbitrators, pursuant to that which is set forth below. The Holder
shall appoint one arbitrator and the Issuing Company shall appoint another
arbitrator within 15 (fifteen) days following the date of an Arbitration
Request, in the understanding that all arbitrators shall be of a different
nationality to the Holder and the Issuing Company. The two appointed arbitrators
shall appoint the third arbitrator by common agreement in a term not to exceed
15 (fifteen) days following the designation of the last of the first two
arbitrators. The arbitrators shall appoint from among them the arbitrator who
shall act as chairman of the arbitration court, within 5 (five) days following
the date of the last of such appointments. If any appointment of the
arbitrators is not made within the terms herein set forth, the ICC shall make
such appointment upon request of any of the parties. The arbitrators must be
able to read, write and fluently speak both the English and Spanish languages,
and must be experts in the matter in question. The hearings shall be carried
out no later than 20 (twenty) business days and the award must be issued no
later than 60 (sixty) business days, after the date of appointment of the third
arbitrator.

 

10.3         Specific
Performance. In any arbitration procedure under this Agreement, the parties
shall be authorized to request a competent judge to order the specific
performance of any obligation under this Agreement and, in the terms of Article
1425 of the Code of Commerce, any precautionary measures.

 

10.4         Applicable
Legislation and Enforcement of Awards. The arbitrators shall decide the
Controversy pursuant to the substantive laws of the United Mexican States. In
case of requiring the forced enforcement of such award in a jurisdiction other
than the United Mexican States, the arbitration agreement and any award
hereunder shall be governed by the United Nations Convention of 1958 on the
Recognition and Enforcement of Foreign Arbitral Awards. The written decision of
the arbitrators, signed by a majority thereof, shall be definitive and
mandatory for the parties. Upon receipt of such award, each party must
immediately (i) adopt the action, (ii) make the changes in the conduction of
its business, or (iii) make the payments or repayments that the arbitration
decision requires, as the case may be. The award may be reviewed and enforced
in any court with competent jurisdiction. Such review will verify the
compliance of the award with the formalities required by the applicable
legislation.

 

10.5         Allocation
of Costs and Currency of the Award. The party against which an award is
entered pursuant to this Section 10., must pay all expenses and costs
that may be accrued by reason of the arbitration proceeding in question,
including any expenses and costs corresponding to the arbitrators and the ICC.
Except for that set forth in immediately preceding sentence, each of the
parties must pay all expenses and costs incurred by such party in connection
with the arbitration proceeding different than those mentioned above. Any
monetary award must be made in Dollars of the United States of America and may
be paid in such currency or in lawful currency of the United Mexican States at
the exchange rate in effect on the date of payment, at the election of the
debtor, free from any tax or other deduction, and must include interest as from
the date of any default or other breach of this Agreement, until the date on
which the award is paid, with a fair interest rate determined by the
arbitrators.

 

10.6         Access
to Documents. The non-confidential books and documents of each party to an
arbitration procedure, as long as they are related to the issues submitted to
arbitration, shall be available for examination of the arbitrators and other
parties during such procedure prior to the applicable hearing.

 

10.7         Successors,
Assignees, etc. The arbitration agreement referred to in this Section
10. shall be mandatory for the successors, assignees and any trustee,
liquidator or receiver of each party.

14.1         In
the event that one or more of the provisions contained in this Agreement, or
the application thereof in any circumstance is declared invalid, illegal or
unenforceable by any competent authority in any respect or by any reason, the

shall seek to fulfill, to the greatest extent possible, the economic, business
and other purposes of the invalid or unenforceable provision.

15.1         This
Agreement is executed in 8 (eight) counterparts, each of which shall be
