writ, injunction, decree, law, statute, rule or regulation applicable to Parent,
Merger Sub or any of their respective properties or assets, except in the case

Stock Purchase may be abandoned at any time prior to the Closing:

                     (a)   by mutual written consent of Parent and FPSH, duly
authorized by the boards of directors (or similar governing bodies) of Parent
and FPSH;

                     (b)   by Parent or FPSH, if (i) any Governmental Entity
shall have enacted, entered, promulgated, issued or enforced a final statute,
rule, regulation, executive order, decree, ruling or injunction (which statute,
rule, regulation, executive order, decree, ruling or injunction the parties
hereto shall use their reasonable best efforts to reverse, overturn or lift) or
taken any other final action restraining, enjoining or otherwise prohibiting the
Stock Purchase or the Related Transactions and such order, decree, ruling or
other action is or shall have become final and nonappealable, or (ii) the Merger
Agreement shall have been terminated in accordance with its terms;

                                      -23-



                     (c)   by FPSH, if (i) there shall have been a material
breach of any of the representations, warranties or covenants of Parent or
Merger Sub under this Agreement, which breach (A) would give rise to the failure
of a condition set forth in Section 7.2 and (B) is not capable of being cured
prior to the Outside Date (as defined in the Merger Agreement) or, if curable,
has not been cured within 20 business days following receipt by Parent of
written notice from FPSH of such breach, or (ii) there shall have been a breach
of any of the representations, warranties or covenants under the Contribution
Agreement, which breach, individually or in the aggregate would reasonably be
expected to have a Parent Material Adverse Effect, a Contributor Material
Adverse Effect (as defined in the Contribution Agreement), a Company Material
Adverse Effect or a Buyer Material Adverse Effect; provided that in the case of
clause (ii), such breach is not capable of being cured prior to the Outside Date
(as defined in the Merger Agreement) or, if curable, has not been cured within
20 business days following receipt by Parent of written notice from FPSH of such
breach; or

                     (d)   by Parent, if there shall have been a material breach
of any of the representations, warranties or covenants of FPSH which breach (A)
would give rise to the failure of a condition set forth in Section 7.1 and (B)
is not capable of being cured prior to the Outside Date (as defined in the
Merger Agreement) or, if curable, has not been cured within 20 business days
following receipt by FPSH of written notice from Parent of such breach.

         Section 8.2.      Effect of Termination. In the event of the
termination and abandonment of this Agreement pursuant to Section 8.1, written
notice thereof shall forthwith be given to the other party or parties specifying
the provision hereof pursuant to which such termination is made, and this
Agreement shall forthwith become void and have no effect, without any liability
on the part of any party hereto or its Affiliates, directors, officers or
stockholders, other than the provisions of this Section 8.2, Section 8.3(a) and
Article IX of this Agreement; provided, however, that nothing contained in this
Section 8.2 shall relieve any party from liability for any willful and material
breach of this Agreement.

         Section 8.3.      Fees and Expenses.

                     (a)   Except as otherwise provided in the Merger Agreement,
if the transactions contemplated by this Agreement are not consummated for any
reason, all costs and expenses incurred in connection with this Agreement shall
be paid by the party incurring such expenses.

                     (b)   If the transactions contemplated by this Agreement
are consummated, on the Closing Date, the parties hereto shall cause the Company
to pay to FPSH by wire transfer of immediately available funds (to the account
or accounts designated by FPSH in writing not less than one business day prior
to the Closing) (i) a transaction fee equal to the amount paid to Savia in cash
pursuant to Section 2.02 of the Exchange Agreement (as defined in the Merger
Agreement), and (ii) all FPSH Expenses; provided, however, that the FPSH
Expenses shall not exceed $7.5 million.

                     (c)   If the transactions contemplated by this Agreement

nacional, S.A. de C.V., Alfonso Romo Garza, Servasa, S.A. de C.V., the ARG
Trust, Fox Paine & Company, LLC and GFA, dated as of April 25, 2003.

         Section 8.4.      Amendment. This Agreement may be amended at any time
by an instrument in writing signed by FPSH and Parent; provided, however, that
any amendment that would prevent or delay the Closing shall also require the
written consent of the Special Committee (as defined in the Merger Agreement),
such consent not to be unreasonably withheld or delayed.

         Section 8.5.      Waiver. At any time prior to the Effective Time: (a)
Parent may (i) extend the time for the performance of any of the obligations or
other acts of FPSH, (ii) waive any inaccuracies in the representations and
warranties of FPSH contained herein or in any document, certificate or writing
delivered pursuant hereto, or (iii) waive compliance by FPSH with any of the
agreements or conditions contained herein, and (b) FPSH may (i) extend the time
for the performance of any of the obligations or other acts of Parent, Merger
Sub or the ARG Trust, (ii) waive any inaccuracies in the representations and
warranties of Parent, Merger Sub or the ARG Trust contained herein or in any
document, certificate or writing delivered pursuant hereto, or (iii) waive
compliance by Parent, Merger Sub or the ARG Trust with any of the agreements or
conditions contained herein; provided, however, that in the case of clauses (a)
and (b), any extension or waiver that would prevent or delay the Closing shall
also require the written consent of the Special Committee (as defined in the
Merger Agreement), such consent not to be unreasonably withheld or delayed. Any
agreement on the part of any party hereto to any such extension or waiver shall
be valid only if set forth in an instrument in writing signed on behalf of such
party. The failure of any party hereto to assert any of its rights hereunder
shall not constitute a waiver of such rights.

         Section 8.6.      Survival. The parties hereto hereby acknowledge that
indemnification with respect to breaches of representations, warranties and
covenants contained in this Agreement shall be made pursuant to the
Indemnification Agreement and that the representations and warranties in this
Agreement shall survive as provided in this Section 8.6 for such purpose. The
representations and warranties in this Agreement shall survive until the
two-year anniversary of the Closing, provided, however, that the representations
and warranties contained in Section 3.6 of this Agreement shall survive
indefinitely. Any covenants or agreements contained herein or made pursuant
hereto that by their terms are to be performed prior to the Closing Date, shall
not survive beyond the Closing Date. Any covenants or agreements contained
herein or made pursuant hereto that by their terms are to be performed in whole
or in part after the Closing Date, shall survive until fully discharged.

         Section 8.7.      Sole Remedy. After the Closing, and conditioned
thereupon, to the extent permitted by law, the indemnities set forth in the
Indemnification Agreement shall be the exclusive remedies of the parties hereto
and their respective officers, directors, employees, agents and Affiliates for
any misrepresentation, breach of warranty or nonfulfillment or failure to be
performed of any covenant or agreement contained in this Agreement, and the
parties shall not be entitled to rescission of this Agreement or to any further
indemnification rights or claims of any nature whatsoever in respect thereof,
all of which the parties hereto hereby waive.

                                   ARTICLE IX

                                  MISCELLANEOUS

         Section 9.1.      Entire Agreement; Assignment. This Agreement and the
Related Agreements (including the schedules and Exhibits hereto and thereto)
constitute the entire agreement among the parties hereto with respect to the
subject matter hereof and supersede all other prior agreements and
understandings, both written and oral, between the parties hereto with respect
to the subject matter hereof. This Agreement shall not be assigned by operation
of law or otherwise. Notwithstanding the foregoing, at Closing, FPSH may assign
its rights and obligations under this Agreement to one or more of its Affiliates
who would qualify as an "FPSH Affiliate Transferee" as defined in the
Stockholders' Agreement, and with respect to Section 2.2 of this Agreement, to
any entity co-investing with FPSH who would qualify as a "Co-Investor
Transferee" under the Stockholders' Agreement; provided, however, that FPSH
remains liable for its obligations hereunder until the Closing occurs at which
time such assignees shall be liable.

         Section 9.2.      Severability. If any provision of this Agreement, or
the application thereof to any Person or circumstance, is held invalid or
unenforceable, the remainder of this Agreement, and the application of such
provision to other Persons or circumstances shall not be affected thereby, and
to such end, the provisions of this Agreement are agreed to be severable. Upon
such determination that any provision is invalid or unenforceable, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties hereto as closely as possible in a mutually
acceptable manner.

         Section 9.3.      Notices. All notices, requests, claims, demands and
other communications hereunder shall be in writing (including by facsimile with
written confirmation thereof) and unless otherwise expressly provided herein,
shall be delivered during normal business hours by hand, by Federal Express or
other nationally recognized overnight commercial delivery service, or by
facsimile notice, confirmation of receipt received, addressed as follows, or to
such other address as may be hereafter notified by the respective parties

         Section 9.4.      Governing Law; Consent to Jurisdiction; Waiver of

accordance with the laws of the State of Delaware, without regard to the

                  (b)      The parties hereto hereby agree and consent to be
subject to the exclusive jurisdiction of the courts of the State of Delaware
sitting in the County of New Castle and the United States District Court for the
State of Delaware in any suit, action or proceeding seeking to enforce any
provision of, or based on any matter arising out of or in connection with, this

the fullest extent permitted by law, (i) any objection that it may now or
hereafter have to laying venue of any suit, action or proceeding brought in such
courts, and (ii) any claim that any suit, action or proceeding brought in such

                  (c)      The ARG Trust irrevocably appoints CT Corporation

appointed agent in the State of Delaware for the service of such process or
summons, and if it fails to maintain such an agent, any such process or summons
may be served by mailing a copy thereof by registered mail, or a form of mail
substantially equivalent thereto, addressed to it at its address as provided for
notices hereunder.

                  (d)      EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT

CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
ACTIONS OF ANY PARTY HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND
ENFORCEMENT THEREOF.

         Section 9.5.     Specific Performance. The parties hereto agree
that irreparable damage would occur if any provision of this Agreement were not
performed in accordance with the terms

                                      -28-



hereof and that the parties shall be entitled, without posting a bond or similar
indemnity, to an injunction or injunctions to prevent breaches of this Agreement
or to enforce specifically the performance of the terms and provisions hereof in
any federal court located in the State of Delaware or any Delaware state court,
in addition to any other remedy to which they are entitled at law or in equity.

         Section 9.6.      Interpretation. When a reference is made in this
Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be
to an Article or Section of or Exhibit or Schedule to this Agreement unless
otherwise indicated. The table of contents and headings contained in this
Agreement are for reference purposes only and shall not affect in any way the

binding upon and inure solely to the benefit of each party hereto and its
successors and permitted assigns, and nothing in this Agreement, express or
implied, is intended to or shall confer upon any other Person any rights,
benefits or remedies of any nature whatsoever under or by reason of this
Agreement.

                  (b)      Notwithstanding anything to the contrary contained
herein, (i) Savia shall be a third party beneficiary of this Agreement and shall
have the right to enforce any right under this Agreement exercisable by Parent
to the extent such right is not enforced by Parent, and (ii) any
representations, warranties or covenants made by FPSH shall be deemed made to
Savia.

                  (c)      The parties hereto acknowledge that the Company would
not have entered into the Merger Agreement had the parties hereto not entered
into this Agreement.

         Section 9.8.      Counterparts. This Agreement may be executed in two
or more counterparts, each of which shall be deemed to be an original, but all
of which shall constitute one and the same agreement.

                                      -29-



         IN WITNESS WHEREOF, each of the parties hereto has caused this
