follows:

              SECTION 3.1.     Closing Date Adjustments.  The Seller and the
Buyer have, in good faith using the Companies' and Southland's then available

sheet of the Companies and Southland as of the opening of business on the
Closing Date, assuming repayment of the notes referred to in Section 2.2 (the
"Estimated Closing Balance Sheet") setting forth an estimate of the Net
Assets in the amount of $19,801,000 dollars (the "Estimated Net Assets").
The Estimated Closing Balance Sheet was prepared in accordance with GAAP,
applied on a basis consistent with, and following the accounting principles,
procedures, policies and methods employed in preparing, the June 30, 2004
Balance Sheet.





                                      -11-


              SECTION 3.2.     Post-Closing Determination.  Not later than 60
calendar days after the Closing Date, the Buyer shall deliver to the Seller
the consolidated balance sheet of the Companies and Southland as of the
opening of business on the Closing Date, assuming repayment of the notes
referred to in Section 2.2 (the "Closing Balance Sheet"), prepared in
accordance with GAAP, applied on a basis consistent with, and following the
accounting principles, procedures, policies and methods employed in
preparing, the June 30, 2004 Balance Sheet (including without limitation with
respect to the computation of reserves) and reflecting the results of an
inventory count to be completed by the Seller as soon as practicable prior to
the Closing Date.  The Closing Balance Sheet shall set forth a calculation of
the Net Assets.  During the preparation of the Closing Balance Sheet by the
Buyer and the period of any dispute with respect to the application of this
Section 3.2, the Seller shall cooperate with the Buyer to the extent
reasonably requested by the Buyer to prepare the Closing Balance Sheet or to
investigate the basis for any dispute.  The Closing Balance Sheet shall be
examined by the Seller, and the Seller shall, not later than 30 calendar days
after receipt of the Closing Balance Sheet, render a report thereon (the
"Closing Balance Sheet Report").  The Closing Balance Sheet Report shall list
those items, if any, to which the Seller takes exception and the Seller's
proposed adjustment.  If the Seller fails to deliver to the Buyer the Closing
Balance Sheet Report within 30 calendar days following receipt of the Closing
Balance Sheet, the Seller shall be deemed to have accepted the Closing
Balance Sheet for the purposes of any adjustment to the Cash Purchase Price
under Section 3.3.  If the Buyer does not give the Seller notice within 20
calendar days following receipt of the Closing Balance Sheet Report, the
Buyer shall be deemed to have accepted the Closing Balance Sheet as adjusted
by the Seller for the purposes of any adjustment to the Cash Purchase Price
under Section 3.3.  If the Buyer gives the Seller notice of objections to the
Closing Balance Sheet Report, and if the Seller and the Buyer are unable,
within 15 calendar days after receipt by the Seller of the notice from the
Buyer of objections, to resolve the disputed exceptions, such disputed
exceptions will be referred to Grant Thornton or another firm of independent
certified public accountants ("Independent Accounting Firm") mutually
acceptable to the Seller and the Buyer.  The Independent Accounting Firm
shall, within 60 days following its selection, deliver to the Seller and the
Buyer a written report determining such disputed exceptions, and its
determinations with respect thereto shall be conclusive and binding upon the
parties hereto for the purposes of any adjustment to the Cash Purchase Price
under Section 3.3.  The fees and disbursements of the Independent Accounting
Firm shall be shared equally by the Buyer, on the one hand, and the Seller,
on the other hand.

              SECTION 3.3.     Post-Closing Adjustment.  The Cash Purchase
Price shall be increased or decreased, as the case may be, by an amount (the
"Adjustment") equal to the difference between the Estimated Net Assets and
the Net Assets as finally determined pursuant to Section 3.2.  If the Net
Assets set forth on the Closing Balance Sheet exceeds the Estimated Net
Assets, the Cash Purchase Price shall be increased by the amount of such
excess and the Buyer shall pay such excess to the Seller.  If the Net Assets
set forth on the Closing Balance Sheet is less than the Estimated Net Assets,
the Cash Purchase Price shall be reduced by the amount of such deficiency and
the Seller shall pay such deficiency to the Buyer.  Any payment under this
Section 3.3 shall be made within three calendar days following the



                                      -12-


preparation or computation and final determination, pursuant to Section 3.2,
of the Closing Balance Sheet by wire transfer of immediately available funds
to such account as the Buyer or the Seller, as the case may be, shall
designate in writing to the Seller or the Buyer, as the case may be.

              SECTION 3.4.     2005 EBIT Target Amount.  The Buyer shall
deliver to the Seller, within ten (10) days following the Buyer's receipt
thereof but in no event later than April 30, 2006 (unless delay in completion
of the 2005 Financial Statements is caused by Leon Dachner Cirano), the
audited consolidated financial statements of the Buyer, its Subsidiaries and
Southland at and for the calendar year ending December 31, 2005 (the "2005
Financial Statements") and the computation of the 2005 EBIT; provided that if
at any time prior to December 31, 2005 an event or change to the operation of
the business which affects the 2005 EBIT calculation is expected to occur and
in the reasonable judgment of Leon Dachner Cirano (or such representative of
the Seller as shall be reasonably acceptable to the Buyer) and Michael Fifer
(or such representative of the Buyer as shall be reasonably acceptable to the
Seller), the computation of the 2005 EBIT should be adjusted in light of such
event or change to the business, Leon Dachner Cirano and Michael Fifer (or
the substitute representatives referred to above) may agree to such
adjustment in writing prior to the occurrence of such event or implementation
of the business change, and the computation of the 2005 EBIT pursuant to this
Section 3.4 shall be adjusted accordingly; provided, however, that to the
extent such event or business change is within the control of the Buyer, such
agreement shall be a condition to the occurrence of such event or
implementation of such business change.  The 2005 Financial Statements shall
be prepared in accordance with GAAP, applied on a basis consistent with, and
following the accounting principles, procedures, policies and methods
employed in preparing, the Financial Statements. The 2005 Financial
Statements shall be examined by the Seller, and the Seller shall, not later
than 30 calendar days after receipt of the 2005 Financial Statements, render
a report thereon (the "2005 Financial Statements Report").  The 2005
Financial Statements Report shall list those items, if any, to which the
Seller takes exception and the Seller's proposed adjustment.  If the Seller
fails to deliver to the Buyer the 2005 Financial Statements Report within 30
calendar days following receipt of the 2005 Financial Statements, the Seller
shall be deemed to have accepted the 2005 Financial Statements for the
purposes of any adjustment to the Cash Purchase Price based on the 2005 EBIT
under Section 3.4.  If the Buyer does not give the Seller notice within 20
calendar days following receipt of the 2005 Financial Statements Report, the
Buyer shall be deemed to have accepted the 2005 Financial Statements as
adjusted by the Seller for the purposes of any adjustment to the Cash
Purchase Price based on the 2005 EBIT under Section 3.4.  If the Buyer gives
the Seller notice of objections to the 2005 Financial Statements Report, and
if the Seller and the Buyer are unable, within 15 calendar days after receipt
by the Seller of the notice from the Buyer of objections, to resolve the
disputed exceptions, such disputed exceptions will be referred to the
Independent Accounting Firm.  The Independent Accounting Firm shall, within
60 days following its selection, deliver to the Seller and the Buyer a
written report determining such disputed exceptions, and its determinations
will be conclusive and binding upon the parties hereto for the purposes of
any adjustment to the Cash Purchase Price based on the 2005 EBIT under
Section 3.4.  The fees and disbursements of the Independent Accounting Firm
shall be shared equally by the Buyer, on the one hand, and the Seller, on the



                                      -13-


other hand. If the 2005 EBIT is less than $6,445,000, the full amount then in
the Escrow Account (as defined in the Escrow Agreement) shall be paid to the
Buyer in accordance with the terms of the Escrow Agreement. If the 2005
Financial Statements are not delivered to the Seller by April 30, 2006
(unless delay in completion of the 2005 Financial Statements is caused by
Leon Dachner Cirano), or if the 2005 EBIT is at least $6,445,000, the full
amount then in the Escrow Account shall be released in accordance with the
terms of the Escrow Agreement.

licenses, permits, subleases and occupancy agreements, together with all
amendments and supplements thereto, with respect to all properties in which
any Company has a leasehold interest, whether as lessor or lessee (each, a

which a Company is a lessee is referred to herein as the "Leased Real
Property").  The Seller has furnished true, complete and accurate copies of
all Leases to the Buyer or its representatives.  No option has been exercised

Company has received any notice from any utility company or municipality of
any fact or condition which could result in the discontinuation of presently
available or otherwise necessary sewer, water, electric, gas, telephone or
other utilities or services for any of the Leased Real Property. The Leased
Real Property, all improvements thereon and thereto, and the operations
therein conducted conform to all applicable health, fire, insurance,
environmental, safety, zoning and building laws, ordinances and
administrative regulations, Licenses and Permits and other regulations,

deferred maintenance items at any Leased Real Property that interfere with or
impede the Companies' use of such properties in the ordinary course of its
business or that any Company is obligated under any of the Leases to repair
or otherwise correct.

              (e)     Except as set forth on Schedule 5.12(e), there are no
guaranties (from the Seller or from other Persons) in favor of the lessors of
any of the Leased Real Property.

              (f)     No Company has sold, assigned, transferred, pledged or

Property.

legal requirements and is adequate for the conduct of the business of the
Companies in the normal course.

or any Company, none of the Leased Real Property is subject to a fee mortgage,

Company or any lessor for breach of any restrictive covenant affecting any
part of the Leased Real Property.

              SECTION 5.13.     Assets of the Companies.

              (a)     The assets, properties and rights of each Company
constitute all of the assets and rights which are used in the operation of
the businesses of such Company immediately prior to the Closing and which are
necessary or required for the conduct of such businesses as currently

owned by the Companies as of the date hereof, except for assets transferred
in the ordinary course of business of (i) the Niples Companies prior to the
Grupo Nicna Reorganization or (ii) the Companies thereafter.  Other than the
assets listed on Schedule 5.13(a), which assets are not used in the
Transferred Business, there are no assets, properties, rights or interests of
any kind or nature that any Company has been using, holding or operating in
its businesses prior to the Closing that will not be used, held or owned by
such Company immediately following the Closing.

              (b)     Each Company has good and marketable title, free and
clear of any Liens, to, or a valid leasehold interest under enforceable leases
in, all of the assets, properties and rights of such Company except, in the
case of Leased Real Property, Liens arising as a result of actions or inactions
of the lessor or owner of such properties unrelated to any default by any of
the Companies or any of the Niples Companies.

to any Company the threat of any claim that the holder of such Intellectual
Property is in violation or infringement of any service mark, patent,
trademark, trade name, trademark or trade name registration, copyright or
copyright registration of any other Person.  The consummation of the
transactions contemplated by this Agreement will not prohibit any Company

involved in any pending or to the best knowledge of the Companies, the Seller
or the Seller Parties, threatened administrative or judicial proceeding, and
to the best knowledge of the Companies, the Seller and the Seller Parties,

Company threatened administrative or judicial proceeding to revoke, cancel,
suspend or declare such License and Permit invalid in any respect.  The
Licenses and Permits are sufficient and adequate in all respects to permit
the continued lawful conduct of the business of each Company in the manner
now conducted and none of the operations of any Company are being conducted
in a manner that violates any of the terms or conditions under which any of
the Licenses and Permits was granted.  The consummation of the transactions
contemplated by this Agreement and the other Transaction Documents will not
result in the termination or suspension of any of the Licenses and Permits.

would constitute such a default.  Other than employment agreements, the

Documents will not result in the acceleration of any obligation of any of the

              SECTION 10.4.     Procedures for Indemnification.

              (a)  If a party entitled to indemnification under this
Section 10 (an "Indemnitee") asserts that a party obligated to indemnify it
under this Section 10 (an "Indemnitor") has become obligated to such
Indemnitee pursuant to Section 10.2 or 10.3, or if any suit, action,
investigation, claim or proceeding is begun, made or instituted as a result
of which the Indemnitor may become obligated to an Indemnitee hereunder, such
Indemnitee shall give written notice to the Indemnitor.  The Indemnitor agrees
to defend, contest or otherwise protect the Indemnitee against any such suit,
action, investigation, claim or proceeding at its sole cost and expense.  The
Indemnitor shall not consent to a settlement of, or the entry of any judgment
arising from, any such suit, action investigation, claim or proceeding unless
it has given 15 days' prior written notice of the same to the Indemnitee and
has obtained the written consent  of the Indemnitee to such settlement or
judgment, which consent will not be withheld if the sole relief is monetary
damages that will be paid in full by the Indemnitor and otherwise will not be
unreasonably withheld.  The Indemnitee shall have the right, but not the
obligation, to participate at its own expense in the defense thereof by
counsel of the Indemnitee's choice and shall in any event cooperate with and
assist the Indemnitor to the extent reasonably possible.  If the Indemnitor
fails timely to defend, contest or otherwise protect against such suit,
action, investigation, claim or proceeding, the Indemnitee shall have the
right to do so, including, without limitation, the right to make any
compromise or settlement thereof, and the Indemnitee shall be entitled to
recover the entire cost thereof from the Indemnitor, including, without
limitation, reasonable attorneys' fees, disbursements and amounts paid as the
result of such suit, action, investigation, claim or proceeding.

              (b)     Neither the Seller nor the Seller Parties will have
liability (for indemnification or otherwise) with respect to the matters
described in Section 10.2(i) (other than for a breach of Sections 5.5, 5.9
5.13(a) or 5.20) until the total of all Losses with respect to such matters
exceeds three hundred seventy five thousand dollars ($375,000), it being
understood that once such amount is exceeded, the Seller and the Seller
Parties shall be jointly and severally liable for the aggregate of all such
Losses (from the first dollar of Loss).  In no event shall any liability of
Seller or the Seller Parties with respect to the matters described in Section
10.2(i) (other than for a breach of Sections 5.5, 5.9, 5.13(a) or 5.20)

a judgment obtained in another jurisdiction) brought in respect to this

Agreement shall be deemed to be an instrument made under the laws of Mexico and
for such purposes shall be governed by, and construed in accordance with, the
laws of the Federal District of Mexico.

              (b)     Each party hereto hereby irrevocably and unconditionally

objection which it may now or hereafter have to the laying of venue of any
suit, action or proceeding arising out of or relating to this Agreement in
any court referred to in paragraph (b) or (c) of this Section 13.2.  Each

each of the Seller Parties hereby confirms and agrees that the Process Agent
has been duly and irrevocably appointed as its agent and true and lawful
attorney-in-fact in its name, place and stead to accept such service of any
and all such writs, process and summonses, and agrees that the failure of the
Process Agent to give any notice of any such service of process to the Seller
Parties shall not impair or affect the validity of such service or of any
judgment based thereon. Each party to this Agreement further irrevocably
consents to service of process in the manner provided for written notices in

this Agreement to serve process in any other manner permitted by law.

transactions contemplated hereby and thereby shall be paid by the party
hereto incurring such fees, expenses and costs.

extent it is not so declared, and all of the other provisions of this
Agreement shall remain in full force and effect.

judgment obtained in another jurisdiction) brought by any party hereto with
respect to this Agreement in the courts of Mexico City, Federal District,
Mexico, in which instance the Spanish version shall be controlling.

              (ii)     No later than 21 Business Days after the Initial

notify Mexican counsel to the Buyer that they wish to submit the Spanish
Translation to Thomas Heather Rodriguez or another lawyer mutually acceptable
to the Buyer and the Seller (the "Mediator") for final resolution of the
Disputed Provisions, and for such purposes (ii) send a copy of this Agreement
and the Spanish Translation to the Mediator, by e-mail, indicating the
Disputed Provisions, a copy of which shall be sent to Mexican counsel to the
Buyer.

              (v)     No later than 30 Business Days after delivery of the
