            (a)   At the Closing (as defined in Section 1.4): (i) UniMark shall
sell, assign, transfer, convey and deliver to Purchaser good and valid title to
the ICMOSA Shares owned by UniMark, free of any Encumbrances, and Purchaser
shall purchase such ICMOSA Shares from UniMark, on the terms and subject to the

the Closing Date (as defined in Section 1.4); and (ii) the aggregate purchase
price payable by the Designated Affiliate for the ICMOSA Shares owned by Rafael

credits, deductions and setoffs), and shall be paid by the Designated Affiliate
to Rafael Vaquero 65 days after the Closing Date.

            (c)   Each of UniMark and Rafael Vaquero waives any right of first
refusal or similar right it or he may have (under any applicable Legal

of the other Contemplated Transactions.

      1.2   SALE OF SPECIFIED ASSETS.

            (a)   At the Closing, UniMark and FoodsSub shall cause to be sold,

price in the Segregated Account.

      1.3   TRANSFER TAXES; NO ASSUMPTION OF LIABILITIES.

            (a)   UniMark and FoodsSub shall bear and pay, and shall reimburse
Purchaser and Purchaser's affiliates for, any sales taxes, use taxes, asset

any liability or obligation of UniMark or FoodsSub in connection with any of the
Contemplated Transactions.

      1.4   CLOSING.

be no later than 15 days after the satisfaction or waiver of the last to be
satisfied or waived of the conditions set forth in Section 5 (other than the
condition set forth in Section 5.2(a), which by its nature is not to be
satisfied until the Closing) and Sections 6.1 and 6.3 (it being understood,
however, that Purchaser shall not be required to proceed with the Closing unless
each condition set forth in Section 5 shall be satisfied or shall have been

balance sheet referred to in clause "(iii)" of the first sentence of Section
2.4(a) that have not yet been collected and those accounts receivable of ICMOSA
that have arisen since May 29, 2004 and have not yet been collected) (i)

usable and saleable by ICMOSA or FoodsSub in the Ordinary Course of Business;
(b) has been priced at the lower of cost or market value using the "first-in,

operations of ICMOSA in the Ordinary Course of Business and (iii) are sufficient
to meet all obligations of ICMOSA under the Supply Agreement.

      2.12  REAL PROPERTY; IHMSA FACILITY; EQUIPMENT.

            (a)   Part 2.12(a) of the Disclosure Schedule sets forth accurate
and complete legal descriptions of all real property owned or purported to be
owned by ICMOSA (the "OWNED REAL PROPERTY"), including all real property
reflected on the audited balance sheet referred to in clause "(iii)" of the

of any Liens, except for: (A) any lien for current taxes not yet due and
payable; and (B) the Liens identified in Part 2.12(a) of the Disclosure

Property, are being supplied to the Owned Real Property and are presently
installed and operating properly.

            (b)   Part 2.12(b) of the Disclosure Schedule sets forth an accurate
and complete description of each real property lease pursuant to which ICMOSA
leases real property from any other Person. (All real property leased to ICMOSA,
including all buildings, structures, fixtures and other improvements leased to
ICMOSA, is referred to as the "LEASED REAL PROPERTY," and, together with the
Owned Real Property, as the "ICMOSA REAL PROPERTY.") Except as set forth in Part
2.12(a) or 2.12(b) of the Disclosure Schedule, the present use and operation of
the ICMOSA Real Property are authorized by, and are in material compliance with,
all applicable zoning, land use, building, fire, health, labor, safety and
environmental laws and other material Legal Requirements. Except as set forth in
Part 2.12(a) or 2.12(b) of the Disclosure Schedule, there is no Legal Proceeding
pending or threatened that challenges or adversely affects, or would challenge
or adversely affect, the continuation of the present ownership, use or operation
of any ICMOSA Real Property. Except as set forth in Part 2.12(a) or 2.12(b) of
the Disclosure Schedule, there is no existing plan or study by any Governmental
Body or by any other Person that challenges or otherwise adversely affects the
continuation of the present ownership, use or operation of any ICMOSA Real
Property. There are no subleases, licenses, occupancy agreements or other
contractual obligations that grant the right of use or occupancy of any of the
ICMOSA Real Property to any Person other than ICMOSA, and no Person is in
possession of any of the ICMOSA Real Property other than ICMOSA.

            (c)   To the best of the knowledge of UniMark and ICMOSA, the IHMSA
Facility and related assets are suitable for the purposes for which they are
intended and are in material compliance with and have at all times since
December 31, 2000 been operated in material compliance with all applicable Legal
Requirements.

            (d)   Part 2.12(d) of the Disclosure Schedule accurately identifies
all material equipment, materials, prototypes, tools, supplies, vehicles,
furniture, fixtures, improvements and other tangible assets owned by ICMOSA, and
accurately sets forth the date of acquisition, original cost and book value of
each of said assets. Part 2.12(d) of the Disclosure Schedule also accurately
identifies each tangible asset leased to ICMOSA. Each asset identified or
required to be identified in Part 2.12(d) of the Disclosure Schedule: (i) is
structurally sound, free of material defects and deficiencies and in good
condition and repair (ordinary wear and tear excepted); (ii) complies in all
respects with, and is being operated and otherwise used in full compliance with,
all applicable Legal Requirements; and (iii) is adequate and appropriate for the
uses to which it is being put. The assets identified in Part 2.12(d) of the
Disclosure Schedule are adequate for the conduct of the business of ICMOSA in
the manner in which such business is currently being conducted. No Person other
than ICMOSA is in possession of any material asset of a type listed on Part
2.12(d) of the Disclosure Schedule that is necessary for or used in the business
of ICMOSA.

      2.13  INTELLECTUAL PROPERTY. Except as set forth in Part 2.13 of the
Disclosure Schedule, neither ICMOSA nor FoodsSub has any rights with respect to
any registered trademark or service mark, and neither ICMOSA nor FoodsSub has
caused to be prepared or submitted any application for the registration of any
trademark or service mark. Except as set forth in Part 2.13 of the Disclosure
Schedule, no registered trademark or service mark, whether or not owned by
ICMOSA or FoodsSub, is necessary for the operation of the business of ICMOSA or
FoodsSub, as such business is now conducted. To the best of the knowledge of
UniMark and ICMOSA, ICMOSA has never infringed (directly, contributorily, by
inducement or otherwise), misappropriated or otherwise violated any Intellectual
Property or any right with respect to any Intellectual Property of any other
Person. Except as set forth in Part 2.13 of the Disclosure Schedule, no
infringement, misappropriation or similar claim has ever been asserted,
threatened or commenced against (a) UniMark with respect to any actual or
alleged action, activity or practice of ICMOSA or FoodsSub or (b) ICMOSA or
FoodsSub.

            (a)   Part 2.14(a) of the Disclosure Schedule identifies and
provides an accurate and complete description of each ICMOSA Contract that

review accurate and complete copies of all Contracts identified in Part 2.14(a)
of the Disclosure Schedule, including all amendments thereto. All FoodsSub
Contracts are listed on Schedule 1.2A or Schedule 1.2B. UniMark and FoodsSub
have allowed Purchaser to review accurate and complete copies of all FoodsSub
Contracts. Except for any specific disclosure in the Disclosure Schedule that
identifies a particular ICMOSA Contract or FoodsSub Contract by name and date
and that calls into question, on the face of such disclosure, the validity,
enforceability or effectiveness of such particular ICMOSA Contract or FoodsSub
Contract, each ICMOSA Contract, and each FoodsSub Contract, is valid and in full

accurate and complete copies of all Tax Returns that have been filed on behalf
of or with respect to ICMOSA since December 31, 1998. The information contained

            (e)   The information set forth in Part 2.18(e) of the Disclosure

      2.19  EMPLOYEE AND LABOR MATTERS.

            (a)   Part 2.19(a)(1) of the Disclosure Schedule accurately sets

including any Key Employee who is on a leave of absence or on layoff status: (i)
the name of such Key Employee and the date as of which such Key Employee was
originally hired by ICMOSA; (ii) such Key Employee's title, and a description of
such Key Employee's duties and responsibilities; (iii) the aggregate dollar

compensation for 2004 exceeded MX$350,000 and (ii) whose employment or other

the best of the knowledge of UniMark and ICMOSA, ICMOSA has terminated the
employment of fewer than 50 of its employees since December 31, 2003.

            (c)   Each employee of ICMOSA is duly registered before the Mexican
Social Security Institute (IMSS) and the National Fund for Worker's Housing

and contributions required to be withheld (under applicable Legal Requirements
or otherwise), and has paid on behalf of each

ICMOSA Associate all Taxes and other contributions required to be paid (under
applicable Legal Requirements or otherwise) on behalf of such ICMOSA Associate.

            (d)   Part 2.19(d) of the Disclosure Schedule accurately identifies
each former employee or director who is receiving or is scheduled to receive (or
whose spouse or other dependent is receiving or is scheduled to receive) any
benefits (whether from ICMOSA or otherwise) relating to such former employee's
or director's employment with or service to ICMOSA; and Part 2.19(d) of the
Disclosure Schedule accurately describes such benefits.

            (e)   The employment of each employee of ICMOSA is terminable by
ICMOSA at will, except as provided under Mexican law and under the terms of the
Collective Bargaining Agreements (as defined in Section 2.19(h)). UniMark and
ICMOSA have caused to be delivered to Purchaser accurate and complete copies of
all employee manuals and handbooks, disclosure materials, policy statements and
other materials relating to the employment of the current and former employees

            (f)   To the best of the knowledge of UniMark and ICMOSA: (i) no Key
Employee intends to terminate his employment with ICMOSA; (ii) no Key Employee
has received an offer to join a business that may be competitive with ICMOSA's

confidentiality agreement, noncompetition agreement or other Contract (with any

Employee of any of his or her duties or responsibilities as an employee of
ICMOSA or (B) ICMOSA's business or operations.

            (g)   Part 2.19(g) of the Disclosure Schedule accurately sets forth,
with respect to each Person that is, or has at any time since December 31, 2002
been, an independent contractor of ICMOSA and that has received or is entitled

hired by ICMOSA; (ii) a description of such Person's duties and
responsibilities; (iii) the aggregate dollar amount of the compensation

ICMOSA with respect to services performed in 2003; (iv) such Person's annualized
compensation for 2004 as of the date of this Agreement; (v) the terms of
compensation of such Person; and (vi) any Governmental Authorization that is
held by such Person and that relates to or is useful in connection with ICMOSA's
business. No Person that is, or has been, an independent contractor of ICMOSA
and that has received or is entitled to receive payments from ICMOSA totaling
more than MX$50,000 in the aggregate could be reclassified as an employee.
Except as set forth in Part 2.19(g) of the Disclosure Schedule, there is not,
and at no time has there been, any independent contractor of ICMOSA who has
provided services to ICMOSA for a period of six consecutive months or longer. No
Person identified in Part 2.19(g) of the Disclosure Schedule is eligible to
participate in any ICMOSA Employee Plan.

            (h)   ICMOSA has executed (i) a Collective Bargaining Agreement
dated January 2, 2003, with the "Industrial Labor Union of Employees in General
of the State of Nuevo Leon C.T.M." and (ii) a Collective Bargaining Agreement
dated October 29, 2003, with the "National Labor Union of Rural and Agricultural
Industry Employees and Agricultural Machinery Operators" (collectively, the

                                      21
<PAGE>

caused accurate and complete copies of the Collective Bargaining Agreements to
be provided to Purchaser. There have been no amendments to the Collective
Bargaining Agreements. ICMOSA has complied in all material respects with each of
the Collective Bargaining Agreements. Each of the Collective Bargaining
Agreements has been registered before the Local Labor Court of the State of
Nuevo Leon and the Federal Labor Court in Mexico City. ICMOSA has not entered
into any Contract with any labor union or similar organization, body or Entity,
other than the Collective Bargaining Agreements.

            (i)   ICMOSA is not engaged, and ICMOSA has never been engaged, in
any unfair labor practice of any nature, including any unfair wage or benefits
practice or practices in violation of any applicable Legal Requirements
involving unsanitary, unhealthy or unsafe labor conditions, the employment of
child, forced, indentured, involuntary, prison or uncompensated labor, the use
of corporal punishment, discrimination based on race, gender, national origin or
religious beliefs or similar employment activities and conditions. For purposes
of this Section 2.19(i), "CHILD" means any individual less than 15 years of age.

            (j)   Except as set forth in Part 2.19(j) of the Disclosure
Schedule: (i) there has never been any slowdown, work stoppage, labor dispute or
union organizing activity, or any similar activity or dispute, affecting ICMOSA;
(ii) there is not now pending, and no Person has threatened, any such slowdown,
work stoppage, labor dispute or union organizing activity or any similar
activity or dispute; (iii) no event has occurred, and no condition or

basis for the commencement of any such slowdown, work stoppage, labor dispute or
union organizing activity or any similar activity or dispute; and (iv) there are
no actions, suits, claims, labor disputes or grievances pending or threatened or
reasonably anticipated relating to any labor, safety or discrimination matters
involving any ICMOSA Associate, including charges of unfair labor practices or
discrimination complaints.

            (k)   Part 2.19(k) of the Disclosure Schedule contains an accurate
and complete list of each ICMOSA Employee Plan and each ICMOSA Employee
Agreement. ICMOSA does not intend and has not committed to establish or enter
into any new ICMOSA Employee Plan or ICMOSA Employee Agreement, or to modify any
ICMOSA Employee Plan or ICMOSA Employee Agreement (except to conform any such
ICMOSA Employee Plan or ICMOSA Employee Agreement to the requirements of any
applicable Legal Requirements, as previously disclosed to Purchaser in writing).

            (l)   UniMark and ICMOSA have caused to be delivered to Purchaser:
(i) accurate and complete copies of all documents setting forth the terms of
each ICMOSA Employee Plan and each ICMOSA Employee Agreement, including all
amendments thereto and all related trust documents; (ii) all reports filed with
or submitted to any Governmental Body in connection with each ICMOSA Employee
Plan; (iii) the most recent summary plan description together with the summaries
of material modifications thereto, if any, required under all applicable Legal
Requirements with respect to each ICMOSA Employee Plan; (iv) all material
written Contracts relating to each ICMOSA Employee Plan, including
administrative service agreements and group insurance contracts; (v) all written
materials provided to any ICMOSA Associate relating to any ICMOSA Employee Plan
and any proposed ICMOSA Employee Plans, including any such materials relating to
any amendments, terminations, establishments, increases

                                      22
<PAGE>

or decreases in benefits, acceleration of payments or vesting or other events
that could result in any Liability to ICMOSA; (vi) all correspondence to or from
any Governmental Body relating to any ICMOSA Employee Plan; and (vii) all
insurance policies in the possession of ICMOSA or UniMark pertaining to
fiduciary liability insurance covering the fiduciaries for each ICMOSA Employee
Plan.

            (m)   ICMOSA and UniMark have performed all obligations required to
be performed by them under each ICMOSA Employee Plan and are not in material
default of, or materially violating, the terms of any ICMOSA Employee Plan.
ICMOSA has no knowledge of any default or violation by any other party to the
terms of any ICMOSA Employee Plan, and each ICMOSA Employee Plan has been
established and maintained substantially in accordance with its terms and in
substantial compliance with all applicable Legal Requirements. There are no
claims or Legal Proceedings pending, threatened or reasonably anticipated (other
than routine claims for benefits) against or with respect to any ICMOSA Employee
Plan or the assets of any ICMOSA Employee Plan. Each ICMOSA Employee Plan can be
amended, terminated or otherwise discontinued after the Closing in accordance
with its terms, without Liability to Purchaser or ICMOSA. There are no audits,
inquiries or Legal Proceedings pending or threatened by any Governmental Body
with respect to any ICMOSA Employee Plan. ICMOSA and UniMark have made all
contributions and other payments required by and due under the terms of each
ICMOSA Employee Plan.

            (n)   Each ICMOSA employee has established a retirement fund account
with a duly authorized Mexican AFORE (Administradora de Fondos para el Retiro).
ICMOSA has no Liability with respect to the establishment or contribution of
retirement funds of employees.

            (o)   No ICMOSA Employee Plan requires ICMOSA to provide retiree
life insurance, retiree health benefits or other retiree employee welfare
benefits to any Person for any reason, except as may be required by applicable
Legal Requirements. Neither ICMOSA nor UniMark has ever represented, promised or
contracted (whether in oral or written form) to any ICMOSA Associate (or to any
group of ICMOSA Associates) that any ICMOSA Associate would be provided with
retiree life insurance, retiree health benefits or other retiree employee
welfare benefits, except to the extent required by applicable Legal
Requirements.

            (p)   Neither the execution and delivery of any of the Transactional
Agreements nor the consummation or performance of any of the Contemplated
Transactions will (either alone or upon the occurrence of any additional or
subsequent events) directly or indirectly result in, or constitute an event
under any ICMOSA Employee Plan, ICMOSA Employee Agreement, trust or loan that
will or may result (either alone or in connection with any other circumstance or
event) in any payment (whether of severance pay or otherwise), acceleration,
forgiveness of indebtedness, vesting, distribution, increase in benefits or
obligation to fund benefits with respect to any ICMOSA Associate.

            (q)   ICMOSA and UniMark: (i) are, and at all times have been, in
substantial compliance with all material Legal Requirements respecting
employment, employment practices, terms and conditions of employment and wages
and hours with respect to ICMOSA Associates; (ii) have withheld and reported all
amounts required by all applicable Legal Requirements or by Contract to be
withheld and reported with respect to wages, salaries and other payments to

                                      23
<PAGE>

ICMOSA Associates; (iii) are not liable for any arrears of wages or any Tax or
penalty for failure to comply with the Legal Requirements applicable of the
foregoing; and (iv) are not liable for any payment to any trust or other fund
governed by or maintained by or on behalf of any Governmental Body with respect
to unemployment compensation benefits, social security or other benefits or
obligations for ICMOSA Associates. There is no pending or threatened or
reasonably anticipated claim or Legal Proceeding against ICMOSA or UniMark under
any worker's compensation policy or long-term disability policy with respect to
any ICMOSA Associate.

            (r)   No ICMOSA Associate has any obligation under any Contract, or
is or subject to any judgment, decree or order of any court or other
Governmental Body, that could interfere with such ICMOSA Associate's efforts to
promote the interests of ICMOSA or that could interfere with the business of
ICMOSA. Neither the execution, delivery or performance of any of the
Transactional Agreements or the conduct of the business of ICMOSA as presently
conducted, nor any activity of any ICMOSA Associate in connection with the
conduct of the business of ICMOSA as presently conducted, will, to the best of
the knowledge of UniMark and ICMOSA, conflict with, result in a breach of the
terms, conditions or provisions of or constitute a default under any Contract by
which any ICMOSA Associate is bound.

            (s)   Part 2.19(s) of the Disclosure Schedule accurately describes
all obligations, responsibilities and Liabilities of UniMark with respect to
ICMOSA Associates and ICMOSA Employee Plans.

            (b)   Except as set forth in Part 2.20(b) of the Disclosure

or other Legal Proceeding against ICMOSA or UniMark in connection with any such
actual, alleged, possible or potential Liability; and no event has occurred, and
no condition or circumstance exists, that may directly or indirectly give rise
to, or result in ICMOSA becoming subject to, any such Liability. Except as set
forth in Part 2.20(b) of the Disclosure Schedule, no Governmental Body has
initiated an inspection visit or an administrative procedure against ICMOSA that
may result in the assessment of administrative sanctions (such as the

has at any time been owned by, leased to, controlled by or used by ICMOSA.

            (d)   Except as specifically disclosed in the Disclosure Schedule,

surface of any real property owned by, leased to, controlled by or used by
ICMOSA, is in reasonably sound condition.

            (f)   UniMark and ICMOSA have caused to be delivered to Purchaser
accurate and complete copies of all material environmental reports and studies
(in the possession of ICMOSA or UniMark) relating to ICMOSA, any activity
conducted by ICMOSA or any property ever owned by, leased to, controlled by or
used by ICMOSA. Neither UniMark nor ICMOSA makes any representation or warranty
as to the accuracy or completeness of the Phase I Environmental Site Assessments
commissioned by Purchaser and dated as of June 28, 2004 (the "PHASE I STUDIES").
UniMark shall be deemed to have disclosed in Part 2.20 of the Disclosure
Schedule: (i) all information expressly disclosed in the Phase I Studies; and
(ii) any additional information that should have been disclosed in the Phase I

actionable professional negligence on behalf of the Person commissioned by
Purchaser to prepare the Phase I Studies.

      2.21  SALE OF PRODUCTS. Each product that has been produced by or on

claim. To the best of the knowledge of UniMark and ICMOSA, none of UniMark,

ICMOSA and FoodsSub in accordance with its terms. Upon the execution of each of
the other Transactional Agreements, each of such other Transactional Agreements
to which UniMark, ICMOSA or FoodsSub is a party will constitute the legal, valid
and binding obligation of each of the parties thereto and will be enforceable
against such parties in accordance with its terms.

constitutes a breach of any representation or warranty made by UniMark, ICMOSA
or FoodsSub in this Agreement; (ii) any event, condition, fact or circumstance
that occurs, arises or exists after the date of this Agreement and that would
cause or constitute a breach of any representation or warranty made by UniMark,
ICMOSA or FoodsSub in this Agreement if (A) such representation or warranty had

permitted to terminate this Agreement pursuant to this Section 7.1(c) if the
failure of the Closing to take place by September 13, 2004 is attributable to a
failure on the part of such party to perform any covenant or obligation in this
Agreement required to be performed by such party at or prior to the Closing and
(ii) UniMark shall not be permitted to terminate this Agreement pursuant to this
Section 7.1(c) unless UniMark shall have made all payments required to be made

            (d)   by either Purchaser or UniMark if a court of competent
jurisdiction or other Governmental Body shall have issued a final and

            (h)   by Purchaser if (i) any of the representations and warranties
set forth in Section 2 shall have been inaccurate as of the date of this
Agreement, or shall have become inaccurate as of a date subsequent to the date
of this Agreement (as if made on such subsequent date), such that the condition
set forth in Section 5.1 would not be satisfied (it being understood that, for
purposes of determining the accuracy of such representations and warranties as
of the date of this Agreement or as of any subsequent date, (A) all materiality
qualifications, and any similar qualifications, contained in such
representations and warranties shall be disregarded and (B) any update of or
modification to the Disclosure Schedule made or purported to have been made on

<PAGE>

obligation of UniMark, ICMOSA, FoodsSub, Rafael Vaquero, Eduardo Vaquero, Ruben
Conchas, David Ziegler or Jakes Jordaan contained in this Agreement shall have
been breached such that the condition set forth in Section 5.2(b) would not be
satisfied; provided, however, that if a breach of a covenant or obligation by
UniMark, ICMOSA, FoodsSub, Rafael Vaquero, Eduardo Vaquero, Ruben Conchas, David
Ziegler or Jakes Jordaan is curable by the breaching party and the breaching
party is continuing to exercise commercially reasonable efforts to cure such
breach, then Purchaser may not terminate this Agreement under this Section
7.1(h) on account of such breach unless such breach shall remain uncured for a
period of 10 days commencing on the date that Purchaser gives the breaching
party notice of such breach; or

                  (i)   by UniMark if (i) any of Purchaser's representations and
      warranties set forth in this Agreement shall be inaccurate as of the date
      of this Agreement, or shall have become inaccurate as of a date subsequent
      to the date of this Agreement (as if made on such subsequent date) such
      that the condition set forth in Section 6.1 would not be satisfied or (ii)
      any of Purchaser's covenants or obligations contained in this Agreement
      shall have been breached such that the condition set forth in Section 6.2
      would not be satisfied; provided, however, that if a breach of a covenant
      or obligation by Purchaser is curable by Purchaser and Purchaser is
      continuing to exercise commercially reasonable efforts to cure such
      breach, then UniMark may not terminate this Agreement under this Section
      7.1(i) on account of such breach unless such breach shall remain uncured
      for a period of 10 days commencing on the date that UniMark gives
      Purchaser notice of such breach.

      7.2   EFFECT OF TERMINATION. In the event of the termination of this
Agreement as provided in Section 7.1, this Agreement shall be of no further
force or effect; provided, however, that (a) this Section 7.2 and Sections 7.3
and 10 shall survive the termination of this Agreement and shall remain in full
force and effect and (b) the termination of this Agreement shall not relieve any
party from any liability for any inaccuracy in or breach of any representation,
warranty, covenant, obligation or other provision contained in this Agreement.

      7.3   PAYMENTS TO PURCHASER.

            (a)   Except as set forth in this Section 7.3 and in Sections
1.3(a), 4.3(b) and 10.6, all fees and expenses incurred in connection with the
Transactional Agreements and the Contemplated Transactions shall be paid by the
party incurring such fees and expenses, whether or not the Closing occurs;
provided, however, that:

                  (i)   if (A) this Agreement is terminated by Purchaser
      pursuant to Section 7.1(f), Section 7.1(g) or Section 7.1(h) or (B) this
      Agreement is terminated by UniMark, then (without limiting any obligation
      of UniMark to make any payment required to be made to Purchaser pursuant
      to clause "(ii)" below) UniMark shall make a nonrefundable cash payment to
      Purchaser, no later than two business days after the termination of this
      Agreement, in an amount equal to the aggregate amount of all
      reimbursements and other payments previously made by Purchaser pursuant to
      Section 4.3; and

                  (ii)  if this Agreement is terminated pursuant to Section
      7.1(f) or Section 7.1(h), then (without limiting any obligation of UniMark
      to make any payment

                                      43
<PAGE>

      required to be made to Purchaser pursuant to clause "(i)" above), UniMark
      shall make a nonrefundable cash payment to Purchaser, no later than two
      business days after the termination of this Agreement, in an amount equal
      to the aggregate amount of all fees and expenses (including all attorneys'
      fees, accountants' fees, financial advisory fees and filing fees) that
      have been paid or that may become payable by or on behalf of Purchaser and
      its affiliates in connection with the preparation and negotiation of the
      Transactional Agreements and otherwise in connection with any of the
      Contemplated Transactions.

            (b)   If UniMark fails to pay when due any amount payable under this
Section 7.3, then (i) UniMark shall reimburse Purchaser for all costs and
expenses (including fees and disbursements of counsel) incurred in connection
with the collection of such overdue amount and the enforcement by Purchaser of
its rights under this Section 7.3 and (ii) UniMark shall pay to Purchaser
interest on such overdue amount (for the period commencing as of the date such
overdue amount was originally required to be paid and ending on the date such
overdue amount is actually paid to Purchaser in full) at a rate per annum 350
basis points over the "prime rate" (as announced by Bank of America or any
successor thereto) in effect on the date such overdue amount was originally
required to be paid.

      7.4   NONEXCLUSIVITY OF TERMINATION RIGHTS. The termination rights
provided in Section 7.1 shall not be deemed to be exclusive. Accordingly, the
exercise by any party of its right to terminate this Agreement pursuant to
Section 7.1 shall not be deemed to be an election of remedies and shall not be
deemed to prejudice, or to constitute or operate as a waiver of, any other right
or remedy that such party may be entitled to exercise (whether under this
Agreement, under any other Contract, under any statute, rule or other Legal
Requirement, at common law, in equity or otherwise).

8. INDEMNIFICATION, ETC.

      8.1   SURVIVAL OF REPRESENTATIONS AND COVENANTS.

            (a)   Except as set forth in Section 8.1(b), the representations,
warranties, covenants and obligations of each party to this Agreement shall
survive (without limitation): (i) the Closing and the sale of the Specified
Assets, and the ICMOSA Shares owned by UniMark, to Purchaser; (ii) any
subsequent sale or other disposition of any or all of the Specified Assets or
ICMOSA Shares by Purchaser; and (iii) the death, dissolution, winding-up or
liquidation of any party to this Agreement. The representations, warranties,
covenants and obligations of UniMark, ICMOSA and FoodsSub, and the rights and
remedies that may be exercised by the Indemnitees, shall not be limited or
otherwise affected by or as a result of any information furnished to, or any
investigation made by or any knowledge of, any of the Indemnitees or any of
their Representatives.

            (b)   The representations and warranties set forth in Sections 2 and
3 shall expire 65 days after the Closing Date; provided, however, that

                  (i)   if a Claim Notice (as defined below) relating to any
      representation or warranty set forth in Section 2 is given to UniMark on
      or prior to the date 65 days after the Closing Date, then, notwithstanding
      anything to the contrary contained in this Section

                                      44
<PAGE>

      8.1, such representation or warranty shall not expire, but rather shall
      remain in full force and effect until such time as each and every claim
      (including any indemnification claim asserted by any Indemnitee under
      Section 8.2) that is based directly or indirectly upon, or that relates
      directly or indirectly to, any inaccuracy or alleged inaccuracy in such
      representation or warranty has been fully and finally resolved, either by
      means of a written settlement agreement executed on behalf of UniMark and
      Purchaser or by means of a final, nonappealable judgment issued by a court
      of competent jurisdiction, and

                  (ii)  if, on or prior to the Closing Date, David Ziegler or
      Jakes Jordaan has actual knowledge of any circumstance that constitutes or
      that has given rise or could be expected to give rise, directly or
      indirectly, to any inaccuracy in any representation or warranty set forth
      in Section 2, then such representation or warranty shall not expire, but
      rather shall remain in full force and effect for an unlimited period of
      time (regardless of whether any Claim Notice relating to such
      representation or warranty is ever given).

For purposes of this Agreement, a "CLAIM NOTICE" relating to a particular
representation or warranty shall be deemed to have been given if any Indemnitee,
acting in good faith, delivers to UniMark a written notice stating that such
Indemnitee believes that there is or has been an inaccuracy in such
representation or warranty and containing (1) a brief description of the
specific facts supporting such Indemnitee's good faith belief that there is or
has been such an inaccuracy and (2) a non-binding, preliminary estimate of the
aggregate dollar amount of the Damages that have arisen and may arise as a
direct or indirect result of such inaccuracy.

      (c)   For purposes of this Agreement, each statement or other item of
information set forth in the Disclosure Schedule or in any update to the
Disclosure Schedule shall be deemed to be a representation and warranty made
jointly and severally by UniMark, ICMOSA and FoodsSub in this Agreement.

      8.2   INDEMNIFICATION BY UNIMARK AND FOODSSUB.

            (a)   UniMark and FoodsSub, jointly and severally, shall hold
harmless and indemnify each of the Indemnitees from and against, and shall
compensate and reimburse each of the Indemnitees for, any Damages that are
directly or indirectly suffered or incurred by any of the Indemnitees or to
which any of the Indemnitees may otherwise become subject at any time
(regardless of whether or not such Damages relate to any third-party claim) and
that arise directly or indirectly from or as a direct or indirect result of, or
are directly or indirectly connected with:

                  (i)   any inaccuracy in any representation or warranty made by
      UniMark, ICMOSA or FoodsSub in this Agreement as of the date of this
      Agreement (without giving effect to any qualification as to materiality or
      any similar qualification contained in such representation or warranty,
      and without giving effect to any update to the Disclosure Schedule);

                  (ii)  any inaccuracy in any representation or warranty made by
      UniMark, ICMOSA or FoodsSub in this Agreement as if such representation
      and warranty had been made on and as of the Closing Date (without giving
      effect to any

                                      45
<PAGE>

      qualification as to materiality or any similar qualification contained in
      such representation or warranty, and without giving effect to any update
      to the Disclosure Schedule);

                  (iii) any inaccuracy in any representation, warranty,
      statement, information or provision contained or incorporated in the
      Disclosure Schedule, in the Closing Certificate or in any other document
      delivered or otherwise made available to Purchaser or any of its
      Representatives by or on behalf of UniMark, ICMOSA or FoodsSub or any
      Representative of UniMark, ICMOSA or FoodsSub;

                  (iv)  any breach of any covenant or obligation of UniMark,
      ICMOSA or FoodsSub contained in any of the Transactional Agreements;

                  (v)   any Liability of UniMark or FoodsSub, or any failure on
      the part of UniMark or FoodsSub to perform or discharge any of its
      Liabilities;

                  (vi)  any Liability to which Purchaser or any of the other
      Indemnitees may become subject and that arises directly or indirectly from
      or relates directly or indirectly to (A) any Taxes payable in connection
      with any of the Contemplated Transactions or (B) any Contract that
      provides for indemnification of any ICMOSA Associate;

                  (vii) any Legal Proceeding relating directly or indirectly to
      any actual or alleged inaccuracy, breach, Liability or matter of the type
      referred to in clause "(i)," "(ii)," "(iii)," "(iv)," "(v)" or "(vi)"
      above (including any Legal Proceeding commenced by any Indemnitee for the
      purpose of enforcing any of its rights under this Section 8).

            (b)   Subject to Section 10.2, neither UniMark nor FoodsSub shall be
required to make any indemnification payment pursuant to Sections 8.2(a)(i),
8.2(a)(ii) and 8.2(a)(iii) until such time as the total amount of all Damages
(including the Damages arising from all inaccuracies in the representations and
warranties of UniMark, ICMOSA and FoodsSub) that have been directly or
indirectly suffered or incurred by any one or more of the Indemnitees, or to
which any one or more of the Indemnitees has or have otherwise become subject,
exceeds U.S.$150,000. (If the total amount of such Damages exceeds U.S.$150,000,
then the Indemnitees shall be entitled to be indemnified against and compensated
and reimbursed for the entire amount of such Damages, and not merely the portion
of such Damages exceeding U.S.$150,000.)

      8.3   SETOFF.

            (a)   Without limiting the generality of anything contained in
Section 10.4, and in addition to any rights of setoff or other rights that
Purchaser or any of the other Indemnitees may have at common law or otherwise,
Purchaser shall have the right to withhold and deduct any sum that may be owed
to any Indemnitee under this Section 8 from any amount otherwise payable (under
Section 1.1(b), under Section 1.2(b) or otherwise) by any Indemnitee to UniMark
or any affiliate of UniMark. The withholding and deduction of any such sum shall
operate for all purposes as a complete discharge (to the extent of such sum) of
the obligation to pay the amount from which such sum was withheld and deducted.

                                      46
<PAGE>

            (b)   If (i) Purchaser withholds and deducts any sum from the amount
payable to FoodsSub under Section 1.2(b) and (ii) within 15 days after the
withholding and deduction of such sum, UniMark disputes the withholding and
deduction of such sum by initiating a binding arbitration proceeding in
accordance with Section 10.12(b), then Purchaser shall cause such sum to remain
in the Segregated Account until such dispute is resolved in accordance with
Section 10.12(b).

      8.4   NONEXCLUSIVITY OF INDEMNIFICATION REMEDIES. The indemnification
remedies and other remedies provided in this Section 8 shall not be deemed to be
exclusive. Accordingly, the exercise by any Person of any of its rights under
this Section 8 shall not be deemed to be an election of remedies and shall not
be deemed to prejudice, or to constitute or operate as a waiver of, any other
right or remedy that such Person may be entitled to exercise (whether under this
Agreement, under any other Contract, under any statute, rule or other Legal
Requirement, at common law, in equity or otherwise).

      8.5   DEFENSE OF THIRD PARTY CLAIMS. In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against
Purchaser, against any other Indemnitee or against any other Person) with
respect to which UniMark or FoodsSub may become obligated to indemnify, hold
harmless, compensate or reimburse any Indemnitee pursuant to this Section 8: (a)
Purchaser shall have the right to control the defense of such claim or Legal
Proceeding; (b) all expenses relating to the defense of such claim or Legal
Proceeding (whether or not incurred by Purchaser) shall be borne and paid
exclusively by UniMark and FoodsSub; (c) UniMark and FoodsSub shall make
available to Purchaser any documents and materials in the possession or control
of either of UniMark or FoodsSub that may be necessary to the defense of such
claim or Legal Proceeding; and (d) Purchaser shall have the right to settle,
adjust or compromise such claim or Legal Proceeding with the consent of UniMark,
which shall not be unreasonably withheld or delayed.

      8.6   EXERCISE OF REMEDIES BY INDEMNITEES OTHER THAN PURCHASER. No
Indemnitee (other than Purchaser or any successor thereto or assign thereof)
shall be permitted to assert any indemnification claim or exercise any other
remedy under this Agreement unless Purchaser (or any successor thereto or assign
thereof) shall have consented to the assertion of such indemnification claim or
the exercise of such other remedy.

9. CERTAIN POST-CLOSING COVENANTS.

      9.1   NO DISSOLUTION BY UNIMARK. UniMark shall not be entitled to commence
or effect any dissolution, winding-up or liquidation of any nature, and shall
not be entitled to authorize or make any liquidating or other distribution to
any of its shareholders, until the later of (a) 65 days after the Closing Date
or (b) the date as of which all obligations of UniMark under the Transactional
Agreements have been fully performed and discharged and any disputes relating
thereto have been settled or otherwise fully resolved.

      9.2   TRANSITION SERVICES. During the 30-day period commencing on the
Closing Date, FoodsSub and UniMark shall provide to Purchaser, without charge,
the services described on Schedule 9.2.

                                      47
<PAGE>

      9.3   PREPARATION OF CLOSING BALANCE SHEET; PAYMENTS BY UNIMARK.

            (a)   Following the Closing, Purchaser shall cause to be prepared a
U.S. dollar-denominated balance sheet of ICMOSA as of the time immediately
following the Closing, but before giving effect to (i) the extinguishment of
ICMOSA's indebtedness to the Mexican Banks, (ii) the purchase by ICMOSA of the
IHMSA Facility, (iii) the cancellation of the accounts receivable of ICMOSA
described in Section 1.4(b)(xvi) and (iv) the cancellation of the accounts
receivable of FoodsSub and UniMark described in Section 1.4(b)(xvii) (the
"CLOSING BALANCE SHEET"). Subject to Section 10.2(d), if UniMark so requests in
writing within ten days after the Closing, Purchaser shall arrange to have the
Closing Balance Sheet audited by an independent accounting firm selected by
Purchaser. On or before the date 65 days after the Closing Date, Purchaser shall
cause to be delivered to UniMark a copy of the Closing Balance Sheet.

            (b)   If the Adjusted Liability Amount (as defined below) exceeds
U.S.$3,600,000, then, within one business day following the delivery of a copy
of the Closing Balance Sheet to UniMark, UniMark shall pay to Purchaser, in
immediately available funds (and in addition to any amount payable by UniMark to
Purchaser pursuant to Section 9.3(c)), the amount by which the Adjusted
Liability Amount exceeds U.S.$3,600,000. For purposes of this Section 9.3,
"ADJUSTED LIABILITY AMOUNT" shall mean the aggregate dollar amount of ICMOSA's
liabilities as reflected on the Closing Balance Sheet, minus the sum of the
dollar amounts of the following liabilities of ICMOSA as determined by Purchaser
based on the information used to prepare the Closing Balance Sheet: (i) ICMOSA's
liability to the Mexican Banks; (ii) ICMOSA's accounts payable to UniMark and
FoodsSub; (iii) ICMOSA's liability to IHMSA for any unpaid rent due with respect
to the IHMSA Facility; and (iv) ICMOSA's liability for deferred taxes.

            (c)   If the Intercompany Receivable Amount (as defined below)
exceeds the Intercompany Payable Amount (as defined below) by more than
U.S.$200,000, then, within one business day following the delivery of a copy of
the Closing Balance Sheet to UniMark, UniMark shall pay to Purchaser, in
immediately available funds (and in addition to any amount payable by UniMark to
Purchaser pursuant to Section 9.3(b)), the amount by which the Intercompany
Receivable Amount exceeds the sum of the Intercompany Payable Amount plus
U.S.$200,000. For purposes of this Section 9.3, (i) "INTERCOMPANY RECEIVABLE
AMOUNT" shall mean the sum of all amounts owed by UniMark to ICMOSA and all
amounts owed by FoodsSub to ICMOSA, in each case immediately prior to the
Closing and before giving effect to the cancellation of the accounts receivable
of ICMOSA described in Section 1.4(b)(xvi), as determined by Purchaser based on
the information used to prepare the Closing Balance Sheet and (ii) "INTERCOMPANY
PAYABLE AMOUNT" shall mean the aggregate dollar amount of all accounts payable
of ICMOSA to UniMark and FoodsSub immediately prior to the Closing, as
determined by Purchaser based on the information used to prepare the Closing
Balance Sheet.

            (d)   Notwithstanding anything to the contrary contained in this
Section 9.3, if the Adjusted Liability Amount is less than U.S.$3,600,000, or if
Purchaser elects to waive its right to require payment from UniMark under this
Section 9.3, then Purchaser shall not be required to deliver a copy of the
Closing Balance Sheet to UniMark and shall not be required to arrange to have
the Closing Balance Sheet audited. Without limiting the generality of anything
contained in Section 10.4, in addition to any rights of setoff or other rights
that Purchaser may

                                      48
<PAGE>

have at common law or otherwise, Purchaser shall have the right to withhold and
deduct any sum that may be owed to Purchaser under this Section 9.3 from any
amount otherwise payable (under Section 1.1(b), under Section 1.2(b) or
otherwise) by Purchaser to UniMark or any affiliate of UniMark. The withholding
and deduction of any such sum shall operate for all purposes as a complete
discharge (to the extent of such sum) of the obligation to pay the amount from
which such sum was withheld and deducted.

      9.4   CONFIDENTIALITY. UniMark and FoodsSub shall ensure that, prior to,
on and at all times after the Closing Date: (a) no press release or other
publicity concerning any of the Contemplated Transactions is issued or otherwise
disseminated by or on behalf of UniMark or FoodsSub without Purchaser's prior
review and written consent; and (b) UniMark, FoodsSub and their Representatives
keep strictly confidential, and neither UniMark nor FoodsSub, nor any
Representative of UniMark or FoodsSub, uses or discloses to any other Person,
any non-public document or other information (including any information obtained
by UniMark pursuant to Section 9.6) that relates directly or indirectly to any
of the Specified Assets or to the business of ICMOSA, Purchaser or any affiliate
of Purchaser.

      9.5   FURTHER ACTIONS. From and after the Closing Date, UniMark, ICMOSA,
FoodsSub, Rafael Vaquero, Eduardo Vaquero, Ruben Conchas, David Ziegler and
Jakes Jordaan shall cooperate with Purchaser and Purchaser's affiliates and
Representatives, and shall execute and deliver such documents and take such
other actions as Purchaser may reasonably request, for the purpose of evidencing
the Contemplated Transactions, putting Purchaser and the Designated Affiliate in
possession and control of the ICMOSA Shares and putting Purchaser in control of
the Specified Assets. Without limiting the generality of the foregoing, from and
after the Closing Date, UniMark and FoodsSub shall promptly remit to Purchaser
any funds that are received by UniMark or FoodsSub and that are included in, or
that represent payment of receivables included in, the Specified Assets or any
of the assets of ICMOSA. UniMark, FoodsSub, Rafael Vaquero, Eduardo Vaquero,
Ruben Conchas, David Ziegler and Jakes Jordaan: (a) hereby irrevocably authorize
Purchaser, at all times on and after the Closing Date, to endorse in the name of
UniMark or FoodsSub any check or other instrument that is made payable to
UniMark or FoodsSub and that represents funds included in, or that represents
the payment of any receivable included in, the Specified Assets or any of the
assets of ICMOSA; and (b) hereby irrevocably nominate, constitute and appoint
Purchaser as the true and lawful attorney-in-fact of UniMark and FoodsSub (with
full power of substitution) effective as of the Closing Date, and hereby
authorizes Purchaser, in the name of and on behalf of UniMark and FoodsSub, to
execute, deliver, acknowledge, certify, file and record any document, to
institute and prosecute any Legal Proceeding and to take any other action (on or
at any time after the Closing Date) that Purchaser may deem appropriate for the
purpose of (i) collecting, asserting, enforcing or perfecting any claim, right
or interest of any kind that is included in or relates to any of the Specified
Assets or the ICMOSA Shares or any of the assets of ICMOSA, (ii) defending or
compromising any claim or Legal Proceeding relating to any of the Specified
Assets or the ICMOSA Shares or any of the assets of ICMOSA or (iii) otherwise
carrying out or facilitating any of the Contemplated Transactions. The power of
attorney referred to in the preceding sentence is and shall be coupled with an
interest and shall be irrevocable, and shall survive the dissolution,
winding-up, liquidation or insolvency of UniMark or FoodsSub and the death or
insolvency of any of Rafael Vaquero, Eduardo Vaquero, Ruben Conchas, David
Ziegler and Jakes Jordaan.

                                      49
<PAGE>

      9.6   ACCESS. Subject to Section 9.4(b), during the 180-day period
commencing on the Closing Date, ICMOSA shall provide an accounting
representative of UniMark satisfactory to Purchaser with reasonable access, upon
reasonable advance notice and during normal business hours, to the accounting
records of ICMOSA for the purpose of enabling UniMark to prepare its
consolidated financial statements as of and for the quarter ended September 30,
2004. In exercising the access rights provided to UniMark, UniMark shall not
interfere in any material respect with the conduct by ICMOSA of its business,
and all expenses incurred in connection with the exercise of the access rights
provided to UniMark shall be borne and paid exclusively by UniMark.

10. MISCELLANEOUS PROVISIONS.

      10.1  LIMITATION ON LIABILITY. Notwithstanding anything to the contrary
contained in this Agreement, except as provided in Section 10.2, the liability
of UniMark, ICMOSA and FoodsSub to Purchaser under this Agreement (whether under
the terms of this Agreement, at common law, in equity or otherwise) shall be
limited to the actual amount of the aggregate purchase price received by UniMark
and FoodsSub from Purchaser pursuant to Sections 1.1(b) and 1.2(b) (plus all
interest payable to FoodsSub pursuant to the final sentence of Section 1.2(c)).
For purposes of the preceding sentence, any amount withheld or deducted (by way
of setoff) by Purchaser under this Agreement shall be deemed received (and, for
purposes of clarification, any such amount so withheld or deducted (by way of
setoff) by Purchaser under this Agreement shall be counted in determining
whether the liability cap referred to in the preceding sentence has been
reached).

      10.2  INAPPLICABILITY OF SECTIONS 8.2(b) AND 10.1. Notwithstanding
anything to the contrary contained in this Agreement, the limitations set forth
in Sections 8.2(b) and 10.1 shall not apply to indemnification obligations,
liabilities or claims arising out of or relating to: (a) any inaccuracy in any
representation or warranty made by UniMark, ICMOSA or FoodsSub of which David
Ziegler or Jakes Jordaan had actual knowledge on or prior to the Closing Date;
(b) any breach of any covenant or obligation by UniMark, ICMOSA or FoodsSub of
which David Ziegler or Jakes Jordaan had actual knowledge on or prior to the
Closing Date; (c) any breach of any covenant or obligation of UniMark or
FoodsSub set forth in Section 9; or (d) any Liability of UniMark or FoodsSub or
any failure on the part of UniMark or FoodsSub to perform or discharge any of
its Liabilities (other than any Liabilities to Purchaser under this Agreement
arising from any inaccuracy in any representation or warranty made by UniMark,
ICMOSA or FoodsSub or any breach of any covenant by UniMark, ICMOSA or FoodsSub,
which are addressed above).

                                       50
<PAGE>

      10.3  JOINT AND SEVERAL LIABILITY OF UNIMARK, ICMOSA AND FOODSSUB:

            (a) Subject to Section 10.3(b), UniMark, ICMOSA and FoodsSub jointly
and severally agree that they shall be jointly and severally liable for the due
and timely compliance with and performance of each of their covenants and
obligations set forth in this Agreement; provided, however, that from and after
the Closing Date, ICMOSA shall cease to be jointly and severally or otherwise
liable for the compliance with or performance of any covenant or obligation of
UniMark or FoodsSub.

            (b) Each of UniMark and FoodsSub waives, and acknowledges and agrees
that it shall not have and shall not exercise or assert or attempt to exercise
or assert, any right of contribution or right of indemnity or any other right or
remedy against ICMOSA in connection with any indemnification obligation or any
other Liability to which UniMark or FoodsSub may become subject under any of the
Transactional Agreements or otherwise in connection with any of the Contemplated
Transactions.

      10.4  SETOFF.

            (a) In addition to any rights of setoff or other rights that
Purchaser may have at common law or otherwise, and subject to Section 8.3(b),
Purchaser shall have the right to withhold and deduct any sum that may be owed
to Purchaser (under Section 8.2(a), under Section 9.3 or otherwise) from any
amount otherwise payable (under Section 1.1(b), under Section 1.2(b) or
otherwise) by Purchaser or any affiliate of Purchaser to UniMark or any
affiliate of UniMark. The withholding and deduction of any such sum shall
operate for all purposes as a complete discharge (to the extent of such sum) of
the obligation to pay the amount from which such sum was withheld and deducted.

            (b) Purchaser shall be entitled to deduct and withhold from any
amount payable by Purchaser pursuant to any of the Transactional Agreements such
amounts as may be required to be deducted or withheld therefrom under any
provision of any state, local or foreign Tax law or under any other applicable
Legal Requirement. To the extent such amounts are so deducted or withheld, such
amounts shall be treated for all purposes under this Agreement as having been
paid to the Person to whom such amounts would otherwise have been paid.

      10.5 FURTHER ASSURANCES. Each of UniMark, ICMOSA and FoodsSub shall
execute and cause to be delivered to Purchaser such instruments and other
documents, and shall take such other actions, as Purchaser may reasonably
request (prior to, at or after the Closing) for the purpose of carrying out or
evidencing any of the Contemplated Transactions.

      10.6 FEES AND EXPENSES. Except as set forth in Section 7.3, UniMark and
FoodsSub shall bear and pay all fees, costs and expenses (including all legal
fees and expenses payable to counsel for ICMOSA and all audit and accounting
fees payable to ICMOSA's outside accountants) that have been incurred or that
are in the future incurred by, on behalf of or for the benefit of UniMark,
ICMOSA or FoodsSub in connection with: (i) the negotiation, preparation and
review of any term sheet or similar document relating to any of the Contemplated
Transactions; (ii) the investigation and review conducted by Purchaser and its

                                       51
<PAGE>

Representatives with respect to ICMOSA's business (and the furnishing of
information to Purchaser and its Representatives in connection with such
investigation and review); (iii) the negotiation, preparation and review of this
Agreement (including the Disclosure Schedule), the other Transactional
Agreements and all certificates, opinions and other instruments and documents
delivered or to be delivered in connection with any of the Contemplated
Transactions; (iv) the preparation and submission of any filing or notice
required to be made or given in connection with any of the Contemplated
Transactions, and the obtaining of any Consent required to be obtained in
connection with any of the Contemplated Transactions; and (v) the consummation
and performance of the Contemplated Transactions;. Under no circumstances shall
ICMOSA be permitted to bear or pay any such fees, costs and expenses.
Notwithstanding anything to the contrary contained in this Section 10.6, UniMark
shall not be required to bear and pay any fees for accounting services that are
rendered after the Closing by Mancera Ernst & Young at the request of Purchaser.

      10.7 ATTORNEYS' FEES. If any legal action relating to any of the
Transactional Agreements or the enforcement of any provision of any of the
Transactional Agreements is brought against any party hereto, the prevailing
party shall be entitled to recover reasonable attorneys' fees, costs and
disbursements (in addition to any other relief to which the prevailing party may
be entitled).

      10.8 NOTICES. Any notice or other communication required or permitted to
be delivered to any party under this Agreement shall be in writing and shall be
deemed properly delivered, given and received when delivered (by hand, by
registered mail, by courier or express delivery service or by facsimile) to the

for convenience of reference only, shall not be deemed to be a part of this
Agreement and shall not be referred to in connection with the construction or
interpretation of this Agreement.

      10.11 COUNTERPARTS; EXCHANGES BY FACSIMILE. This Agreement may be executed
in several counterparts, each of which shall constitute an original and all of
which, when taken together, shall constitute one agreement. The exchange of a
fully executed Agreement (in counterparts or otherwise) by facsimile shall be
sufficient to bind the parties to the terms and conditions of this Agreement.

      10.12 GOVERNING LAW; VENUE.

            (a) This Agreement shall be construed in accordance with, and
governed in all respects by, the internal laws of the State of Delaware (without
giving effect to principles of conflicts of laws).

            (b) Any controversy, dispute or claim arising out of, or relating
to, this Agreement or the breach or alleged breach hereof, or affecting this
Agreement in any way, shall be adjudicated by binding arbitration administered
by the American Arbitration Association ("AAA") in accordance with its
International Arbitration Rules then in effect (the "IAR"). Any such arbitration
shall be conducted in Delaware by one arbitrator to be mutually selected by
Purchaser and UniMark in accordance with the IAR, and the language of the
arbitration shall be English. If Purchaser and UniMark fail to mutually select
an arbitrator within 15 business days after any such controversy, dispute or
claim is submitted to arbitration, then the arbitrator shall be selected by AAA
in accordance with the IAR. The parties will participate in the arbitration in
good faith and will share equally in its costs. Each party will bear its own
attorneys' fees relating to the arbitration unless the arbitrator decides
otherwise. By further agreement of the parties or direction of the arbitrator,
proceedings that, in the judgment of the arbitrator, are not dependent on the
credibility of a testifying witness may be held other than in person, such as
via telephone conference. The parties agree to use commercially reasonable
efforts to cause the arbitration hearing to be conducted within 120 days after
the appointment of the arbitrator, and to use commercially reasonable efforts to
cause the decision of the arbitrator to be furnished within 15 days after the
conclusion of the arbitration hearing. The final decision of the arbitrator
shall be furnished to the parties to this Agreement in writing and shall
constitute a conclusive

                                       54
<PAGE>

determination of the issues in question, binding upon the parties. If judicial
enforcement or review of such arbitrator's award is sought by any party,
judgment may be entered upon such award in any court of competent jurisdiction.
The provisions of this section may be enforced by any court of competent
jurisdiction, and the party seeking enforcement shall be entitled to an award of
all costs, fees and expenses, including attorneys' fees, relating to the
enforcement proceedings to be paid by the party against whom enforcement is
ordered.

            (c) Each party to this Agreement agrees that the provisions of this
Section 10.12 shall not apply to resolution of any controversy, dispute or claim
arising out of, or relating to, any Transactional Agreement other than this
Agreement.

      10.13 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon:

prior to the Closing), UniMark or FoodsSub may assign or delegate any of its
rights or obligations under this Agreement, in whole or in part, to any other
Person, and any attempted assignment or delegation of any of such rights or
obligations shall be void and of no force or effect. Purchaser may freely assign
any or all of its rights under this Agreement (including its indemnification
rights under Section 8), in whole or in part, to any other Person without
obtaining the consent or approval of any other party hereto or of any other
Person.

      10.14 REMEDIES CUMULATIVE; SPECIFIC PERFORMANCE. The rights and remedies

UniMark, ICMOSA and FoodsSub agrees that: (a) in the event of any breach or
threatened breach by UniMark, ICMOSA or FoodsSub of any covenant, obligation or
other provision set forth in this Agreement, Purchaser shall be entitled (in
addition to any other remedy that may be available to it) to (i) a decree or
order of specific performance or mandamus to enforce the observance and
performance of such covenant, obligation or other provision and (ii) an
injunction restraining such breach or threatened breach; and (b) neither
Purchaser nor any other Indemnitee shall be required to provide any bond or
other security in connection with any such decree, order or injunction or in
connection with any related action or Legal Proceeding.

      10.15 WAIVER.

            (a) No failure on the part of any Person to exercise any power,
right, privilege or remedy under this Agreement, and no delay on the part of any
Person in exercising any power, right, privilege or remedy under this Agreement,
shall operate as a waiver of such power, right, privilege or remedy; and no
single or partial exercise of any such power, right, privilege or remedy shall
preclude any other or further exercise thereof or of any other power, right,
privilege or remedy.

            (b) No Person shall be deemed to have waived any claim arising out
of this Agreement, or any power, right, privilege or remedy under this
Agreement, unless the waiver of

                                       55
<PAGE>

such claim, power, right, privilege or remedy is expressly set forth in a
written instrument duly executed and delivered on behalf of such Person; and any
such waiver shall not be applicable or have any effect except in the specific
instance in which it is given.

      10.16 AMENDMENTS. This Agreement may not be amended, modified, altered or
supplemented other than by means of a written instrument duly executed and
delivered on behalf of Purchaser and UniMark.

      10.17 SEVERABILITY. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions of this
Agreement or the validity or enforceability of the offending term or provision
in any other situation or in any other jurisdiction. If a final judgment of a
court of competent jurisdiction declares that any term or provision of this
Agreement is invalid or unenforceable, the parties hereto agree (a) that the
court making such determination shall have the power to limit such term or
provision, to delete specific words or phrases from such term or provision or to
replace such term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision and (b) that this Agreement shall be enforceable
as so modified. In the event such court does not exercise the power granted to
it in the prior sentence, the parties hereto agree to replace such invalid or
unenforceable term or provision with a valid and enforceable term or provision
that will achieve, to the extent possible, the economic, business and other
purposes of such invalid or unenforceable term.

      10.18 PARTIES IN INTEREST. Except for the provisions of Section 8, none of
the provisions of this Agreement is intended to provide any rights or remedies
to any Person other than the parties hereto and their respective successors and
assigns (if any).

understanding of the parties relating to the subject matter thereof and

be applied in the construction or interpretation of this Agreement.

            (c) As used in this Agreement, the words "include" and "including,"
and variations thereof, shall not be deemed to be terms of limitation, but
rather shall be deemed to be followed by the words "without limitation."

EXHIBIT 10.1

AMENDED AND RESTATED

EMPLOYMENT AGREEMENT

     This Employment Agreement (the “Agreement”) is made as of July 7, 2004 by
and between Michaels Stores, Inc., a Delaware corporation (the “Company”), and
R. Michael Rouleau (“Executive”). This Agreement amends and completely
restates the Employment Agreement dated March 20, 2001, as amended on July 16,
2002, between Executive and the Company.

     The parties hereto agree as follows:

	1.	 	Employment. The Company agrees to employ Executive and Executive accepts
such employment for the period beginning as of the date hereof and ending
on January 31, 2008, subject to earlier termination pursuant to Paragraph
1(d). After January 31, 2008, this Agreement will continue for successive
one-year terms unless the Company gives written notice to Executive
pursuant to Paragraph 4 of this Agreement at least 120 days prior to the
expiration of any term of this Agreement that the Agreement will not be
renewed. If a Change in Control of the Company (as hereinafter defined)
shall have occurred during any term of this Agreement, this Agreement
shall continue in effect until the term of the Agreement expires.

	 	(a)	 	Salary, Bonus and Benefits. During the term of this
Agreement, the Company will pay Executive a base salary (“Base
Salary”) of $675,000 per annum, or such higher amount as the
Company’s Board of Directors or an appropriate committee thereof
shall determine in its sole discretion. Base Salary will be paid in
equal bi-weekly installments. On or about April 1 of each year
during the term of this Agreement, Executive shall be eligible to
receive a bonus based on the Company’s applicable bonus plan. If a
Change in Control of the Company shall have occurred during any term
of this Agreement, Executive shall be entitled, to the extent
permitted by applicable law, to receive employee benefits under, and
participate in for the remaining term of the Agreement, all employee
benefit plans to which Executive was entitled immediately prior to
the date of the Change in Control, including but not limited to any
applicable pension plan, retirement plan, stock option plan,
employee stock ownership, 401(k) savings plan, disability insurance
plan, life insurance plan, medical and dental insurance plans.
	 
	 	(b)	 	Additional Benefits. In addition to the salary and any bonus
payable to Executive pursuant to Paragraph 1(a), Executive will be
entitled during the term of this Agreement to health insurance, life
insurance, disability insurance, five weeks of vacation annually, a
Company-paid automobile, and such other employment-related benefits
that the Company provides to its executive employees, as well as any
perquisites the Board of Directors or an appropriate committee
thereof may establish. The Company shall reimburse Executive, in
accordance with its standard expense reporting and reimbursement
policies in effect from time to time, for all out-of-pocket expenses
which Executive shall incur in connection with his services for the
Company.

 

 

	 	(c)	 	Services. During the term of this Agreement, Executive will
serve as Chief Executive Officer of the Company and will perform
such services of an executive and administrative nature for the
Company and its subsidiaries as the Company’s Board of Directors
and/or the Company’s Chairman of the Board of Directors may from
time to time direct. It is the intention of the parties that,
subject to the directives of the Company’s Board of Directors and
its Chairman, Executive’s principal responsibilities shall be to
direct the day to day management of the Company. Executive will
devote all of his business time and attention (except for vacation
periods and reasonable periods of illness or other incapacity) to
the business of the Company and its subsidiaries.
	 
	 	(d)	 	Termination; Severance Pay. The term of this Agreement will
terminate upon the first to occur of (i) January 31, 2008, (ii)
Executive’s death or permanent disability (as determined by the
Board of Directors in its good faith judgment) or (iii) the date on
which the Company’s Board of Directors terminates Executive’s
employment for Cause (as defined below). In the event that the
Company shall terminate Executive’s employment prior to January 31,
2008, otherwise than pursuant to clause (ii) or (iii) above, the
Company shall pay severance pay to Executive by continuing the Base
Salary, as well as all additional benefits described in Paragraph
1(b) and in effect at the time of such termination (other than
medical, dental and vision benefits, which will be provided only on
the terms set forth in Paragraph 1(e)), until January 31, 2008, and
by paying Executive a prorated bonus for the fiscal year of the
Company in which such termination occurs, if Executive would have
earned any bonus under the Company’s bonus plan for such fiscal
year. Such payments of Base Salary shall be made in bi-weekly
installments, and such prorated bonus, if any, shall be paid when
bonuses for such fiscal year are paid to Company employees in the
ordinary course of business. For purposes of this Agreement,
“Cause” shall mean by determination of the Company’s Board of
Directors in its good faith judgment that Executive has: (1)
knowingly committed gross misconduct in the performance of his
duties, (2) knowingly committed gross negligence or gross
nonfeasance in the performance of his duties, (3) committed an act
of financial dishonesty against the Company or any of its
subsidiaries, parents or affiliates, or (4) committed any felony
involving moral turpitude.
	 
	 	 	 	In the event this Agreement is terminated at any time and for
any reason, (i) Executive will have the option to purchase the
Company-paid automobile in his possession at the depreciated book
value of said automobile; and (ii) Executive will automatically
become the owner of his Company-paid whole life insurance policies.
	 
	 	(e)	 	Medical Benefits after Termination of Employment. If, at or
before the termination of this Agreement (including any extensions
of the term of this Agreement), Executive retires from the Company
or his employment is terminated by the Company without Cause or his
employment terminates by reason of permanent disability (within the
meaning of that term under Paragraph 1(d)), Executive and his
current spouse will continue to participate in

2

 

	 	 	 	the Michaels Stores, Inc. Medical, Dental and Vision Care Plan (the
“Plan”) on the same basis as that available from time to time to
senior executive officers of the Company and their eligible
dependents, except as otherwise provided in this Paragraph 1(e).
Post-termination benefits provided to Executive under the Plan will
be coordinated with Medicare coverage as if Executive had applied
for and were receiving benefits under both Medicare Part A and
Medicare Part B, with Medicare providing primary coverage and the
Plan providing secondary or supplemental coverage. When
Executive’s spouse becomes eligible for Medicare, benefits provided
to her under the Plan after Executive’s retirement or other
termination of employment will also be coordinated with Medicare
coverage as if she had applied for and were receiving benefits
under both Medicare Part A and Medicare Part B, with Medicare
providing primary coverage and the Plan providing secondary or
supplemental coverage. The Company will assist Executive and his
spouse in filing claims and coordinating Plan benefits with
Medicare. Post-termination benefits will be provided under the
Plan to Executive until the earlier of his death or the date he
becomes entitled to medical benefits from another employer and will
be provided to Executive’s spouse until the earliest of her death,
Executive’s death, the date she becomes entitled to medical
benefits from another employer or the date she no longer qualifies
as an eligible dependent under the Plan; provided, however, that if
Executive’s spouse is receiving post-termination benefits under the
Plan at the time of Executive’s death but has not attained age 65,
such post-termination benefits will continue to be provided to
Executive’s spouse until her 65th birthday. The Company will bear
the full cost of post-termination benefits provided to Executive
and his spouse under the Plan (other than the cost of Medicare
premiums). If the Plan is unable to provide Executive and his
spouse with the post-termination coverage provided in this
Paragraph 1(e), the Company will purchase health insurance for
Executive and his spouse that provides, to the extent practicable,
reasonably comparable benefits. Notwithstanding the foregoing
provisions, neither Executive nor his spouse will be entitled to
the benefits provided by this Paragraph 1(e) in the event the
Company terminates Executive’s employment for Cause.
	 
	 	 	 	If, at or before the termination of this Agreement (including
any extensions of the term of this Agreement), Executive’s
employment terminates by reason of his death, Executive’s current
spouse will continue to participate in the Plan on the same basis
described in the preceding paragraph of this Paragraph 1(e) as if
Executive’s death had occurred after his retirement from the
Company.
	 
	 	(f)	 	Stock Options. In the event this Agreement is terminated at
any time and for any reason, each outstanding option to purchase
common stock of the Company held by Executive at such termination
will become 100% vested and exercisable and (provided that
Executive’s employment has not been terminated for Cause) will
expire, notwithstanding the stated expiration date of such option,
one day prior to the fifth anniversary of such termination. In the
event of any conflict between the terms of this Paragraph 1(f) and
the terms contained in any

3

 

	 	 	 	document evidencing any such option, the terms of this Paragraph
1(f) will control.

	2.	 	Confidential Information. Executive acknowledges that the trade secrets
and similar proprietary information obtained by him during the course of
his employment with the Company (including his employment prior to the
date of this Agreement), concerning the business or affairs of the Company
and its subsidiaries are the property of the Company. Therefore,
Executive agrees that, at no time during or after the term of this
Agreement, will he disclose to any unauthorized person or use for his own
account any of such information or data without the written consent of the
Chairman of the Board of Directors, unless and to the extent that the
aforementioned matters become generally known to and available for use by
the public other than as a result of Executive’s acts or omissions to act.
Executive agrees to deliver to the Company at the termination of his
employment, or at any other time the Company may request, all memoranda,
notes, plans, records, reports and other documents (and copies thereof)
relating to the business of the Company and its subsidiaries which he may
then possess or have under his control.
	 
	3.	 	Change in Control. For purposes of this Agreement, the term “Change in
Control” means the occurrence of any of the following events:

	 	(a)	 	the Company is merged, consolidated or reorganized into or
with another corporation or other legal person, and as a result of
such merger, consolidation or reorganization less than two-thirds of
the combined voting power of the then-outstanding securities
entitled to vote generally in the election of directors (“Voting
Stock”) of such corporation or person immediately after such
transaction are held in the aggregate by the holders of Voting Stock
of the Company immediately prior to such transaction;
	 
	 	(b)	 	the Company sells or otherwise transfers all or substantially
all of its assets to another corporation or other legal person, and
as a result of such sale or transfer less than two-thirds of the
combined voting power of the then-outstanding Voting Stock of such
corporation or person immediately after such sale or transfer is
held in the aggregate by the holders of Voting Stock of the Company
immediately prior to such sale or transfer;
	 
	 	(c)	 	there is a report filed on Schedule 13D or Schedule 14D-1 (or
any successor schedule, form or report), each as promulgated
pursuant to the Securities Exchange Act of 1934, as amended (the
“Act”), disclosing that any person (as the term “person” is used in
Section 13(d)(3) or Section 14(d)(2) of the Act) has become the
beneficial owner (as the term “beneficial owner” is defined under
Rule 13d-3 or any successor rule or regulation promulgated under the
Act) of securities representing 20% or more of the combined voting
power of the then-outstanding Voting Stock of the Company;
	 
	 	(d)	 	the Company files a report or proxy statement with the
Securities and Exchange Commission pursuant to the Act disclosing in
response to Form 8-K or Schedule 14A (or any successor schedule,
form or report or item therein) that a

4

 

	 	 	 	change in control of the Company has occurred or will occur in the
future pursuant to any then-existing contract or transaction; or
	 
	 	(e)	 	if, during any period of two consecutive years, individuals
who at the beginning of any such period constitute the directors of
the Company cease for any reason to constitute at least a majority
thereof; provided, however, that for purposes of this Paragraph 3(e)
each director who is first elected, or first nominated for election
by the Company’s stockholders, by a vote of at least two-thirds of
the directors of the Company (or a committee thereof) then still in
office who were directors of the Company at the beginning of any
such period will be deemed to have been a director of the Company at
the beginning of such period.

	 	 	Notwithstanding the foregoing provisions of Paragraph 3(c) or (d) above,
unless otherwise determined in a specific case by majority vote of the
Board, a “Change in Control” will not be deemed to have occurred for
purposes of Paragraph 3(c) or (d) above solely because (A) the Company,
(B) a Subsidiary or (C) any Company-sponsored employee benefit plan of
the Company or any Subsidiary either files or becomes obligated to file a
report or a proxy statement under or in response to Schedule 13D,
Schedule 14D-1, Form 8-K or Schedule 14A (or any successor schedule, form
or report or item therein) under the Act disclosing beneficial ownership
by it of shares of Voting Stock of the Company, whether in excess of 20%
or otherwise, or because the Company reports that a change in control of
the Company has occurred or will occur in the future by reason of such
beneficial ownership or any decrease thereof.
