                            ASSET PURCHASE AGREEMENT

         THIS ASSET PURCHASE AGREEMENT (this "Agreement") is made and entered
into this 1st day of September, 2005, by and between READY MIX USA, LLC, a
Delaware limited liability company ("Buyer") and RMC MID-ATLANTIC, LLC, a South
Carolina limited liability company ("Seller").

                                R E C I T A L S:

         WHEREAS, Seller desires to sell, and Buyer desires to purchase,
certain of the assets of Seller, for the consideration and on the terms and
conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the foregoing premises and the
agreements and undertakings contained herein, and for other good and valuable
consideration the receipt and sufficiency of which are hereby acknowledged,
Buyer and Seller, intending to be legally bound, hereby agree as follows:

                                  ARTICLE 1.

                                  DEFINITIONS

         1.1 General Definitions. For purposes of this Agreement, the words and
phrases defined in Section 10.18 shall have the meanings specified therein.

                                  ARTICLE 2.

                               PURCHASE OF ASSETS

         2.1 Sale and Purchase of Assets. At the Closing, Seller shall sell,
transfer, convey, assign and deliver to Buyer, and Buyer shall purchase and
acquire from Seller, those assets described on Schedule 2.1(a) which are
currently owned by Seller and used or intended for use primarily in, or which
are being utilized or operated by Seller or any of its Affiliates primarily in
its ready mix concrete, concrete block, and building materials business
locations located in the State of Georgia (the "Seller Assets") and the
business associated with the Seller Assets (the "Seller Business"). The
locations listed on Schedule 2.1(a)-1 are referred to sometimes herein as the
"Seller Business Locations." Notwithstanding the foregoing, the assets,
properties and rights described on Schedule 2.1(b) shall not be transferred,
conveyed, assigned or delivered to Buyer under this Agreement (the "Retained
Seller Assets"). For the avoidance of doubt, Buyer hereby acknowledges that (a)
CEMEX, Inc., a Louisiana corporation and Affiliate of Seller, owns and operates
businesses in Brunswick, Georgia and (b) such businesses and the associated
assets are Retained Seller Assets.

         2.2 Prorations.

         Seller and Buyer each acknowledge and agree that Seller shall be
responsible for the expenses relating to the Seller Assets (except to the
extent such amount is reflected in the Seller Working Capital Statement) up to
and through the Closing Date, and Buyer shall be responsible for the expenses
relating to the Seller Assets after the Closing Date (for example, ad valorem
taxes and utilities) and that such expenses relating to the Seller Assets up to
and through the Closing Date shall be paid by Seller at or before the Closing
Date. To the extent that a period of time for the assessment of any of the
expenses (for example, property taxes) shall be due both before and after the
Closing Date, the same shall be prorated as of the Closing Date. Seller and
Buyer acknowledge and agree that one or more of such prorations may occur or be
reconciled subsequent to the Closing Date.

         2.3 Payment of Purchase Price; Allocation; Adjustments.

         (a) The purchase price for the Seller Assets to be paid by wire
transfer of immediately available funds at the Closing shall be One Hundred
Twenty-Four Million Five Hundred Sixty Thousand Dollars ($124,560,000) (the
"Closing Purchase Price"), plus the assumption of the Assumed Liabilities in
accordance with Section 2.4. The Closing Purchase Price includes an estimated
purchase price for the Closing Working Capital in the amount of Thirty-Three
Million Dollars ($33,000,000), which amount is subject to adjustment to be made
following the Closing Date pursuant to Section 2.3(b) and Section 2.3(c) below.

         (b) Following the Closing, in accordance with Section 2.3(c) below,
the Closing Purchase Price shall be (i) increased by the amount by which (A)
the value of the inventory of sand, gravel, cement, admixtures, fuel, other raw
material and finished goods on hand constituting Seller Inventory, which shall
all be valued at book value as of the Effective Time (the "Materials Inventory
Value"); plus (B) the value of the inventory of tools, parts and related items
constituting Seller Inventory, which shall all be valued at book value as of
the Effective Time (the "Parts Inventory Value"); plus (C) the aggregate amount
of the Seller Accounts Receivable, valued at face value as of the Effective
Time (the sum of Clauses (A), (B) and (C) is hereafter referred to as the
"Closing Working Capital"), exceeds Thirty-Three Million Dollars ($33,000,000)
or (ii) decreased by the amount by which the Closing Working Capital is less
than Thirty-Three Million Dollars ($33,000,000). For the purpose of calculating
the Seller Accounts Receivable: (i) accounts receivable that are less than
sixty (60) days past due will be valued at face value as of the Effective Time;
(ii) accounts receivable that are more than sixty (60) days and less than
ninety (90) days past due will be valued at ninety percent (90%) of face value
as of the Effective Time; and (iii) accounts receivable that are more than
ninety (90) days past due will be valued at seventy-five percent (75%) of face
value as of the Effective Time.

                  (c) (i) Within thirty (30) days after the Closing Date,
         Seller shall deliver to the Buyer a working capital statement
         reflecting the current assets assigned by Seller pursuant to this
         Agreement as of the Effective Time, with each item valued as
         contemplated in Section 2.2 and 2.3(b) as the case may be (the "Seller
         Working Capital Statement") along with a statement of the amount by
         which the Closing Working Capital exceeds or is less than Thirty-Three
         Million Dollars ($33,000,000) (the "Working Capital Adjustment
         Amount") and the amount of the final purchase price (the "Purchase
         Price").

                  (ii) Upon receipt of the Seller Working Capital Statement,
         Buyer and its independent certified public accountants shall have the
         right during the succeeding 30-day period to review and audit the
         accounts represented by the line items set forth on the Seller Working
         Capital Statement and to examine and review all records and work
         papers and other supporting documents used to prepare such statement.
         Seller shall give Buyer full access at all reasonable times to the
         working papers relating to the Seller Working Capital Statement,
         including any descriptions of the methodology, procedures, internal
         audits and analysis undertaken in connection with the preparation of
         the Seller Working Capital Statement. Buyer shall notify Seller in
         writing, on or before the last day of the 30-day period, of any good
         faith objections to the Seller Working Capital Statement or the
         Working Capital Adjustment Amount, setting forth a detailed
         explanation of the objections and the dollar amount of each such
         objection. If Buyer does not deliver such notice within such 30-day
         period, the Seller Working Capital Statement, the Working Capital
         Adjustment Amount and the Purchase Price shall be deemed to have been
         irrevocably accepted by Buyer.

                  (iii) If Buyer in good faith objects to line items set forth
         on the Seller Working Capital Statement or the Working Capital
         Adjustment Amount, the parties shall attempt to resolve any such
         objections within thirty (30) days of receipt by the corresponding
         party of any such objections. If the parties are unable to resolve the
         matter within such 30-day period, they shall jointly appoint an
         impartial nationally recognized independent certified public
         accounting firm (the "Impartial Accounting Firm") mutually acceptable
         to the parties (or, if they cannot agree on a mutually acceptable
         firm, they shall cause their respective accounting firms to select
         such firm) within five (5) days after the end of such 30-day period to
         resolve any such remaining matters. Any such resolution shall be
         conclusive and binding on the parties and the fees of the Impartial
         Accounting Firm shall be borne as the Impartial Accounting Firm shall
         determine after considering the positions asserted by the parties in
         light of its final decision. The parties shall fully cooperate with
         the Impartial Accounting Firm. The Impartial Accounting Firm shall be
         instructed to reach its conclusion regarding the dispute within thirty
         (30) days of its appointment to settle the dispute.

                  (iv) Adjustments to the values contemplated in paragraph (b)
         of this Section 2.3 shall be made pursuant to the Seller Working
         Capital Statement, within thirty (30) days after their acceptance by
         the parties or the resolution of all disputes in connection therewith,
         pursuant to the provisions of this Section 2.3(c). In the event the
         Closing Working Capital exceeds Thirty-Three Million Dollars
         ($33,000,000), Buyer shall pay to Seller the amount of such excess by
         wire transfer of immediately available funds. In the event the Closing
         Working Capital is less than Thirty-Three Million Dollars
         ($33,000,000), Seller shall pay to Buyer the amount of such shortfall
         by wire transfer of immediately available funds.

         (d) Payments to Seller or Buyer pursuant to this Section 2.3 shall be
made to the respective accounts set forth on Schedule 2.3(d) not later than ten
(10) days following the date the Seller Working Capital Statement becomes
final.

                  (e)(i) Within sixty (60) days after the Closing Date, the
         Buyer shall deliver to the Seller a draft of schedule (the "Allocation
         Schedule") allocating the Purchase Price and the amount of Assumed
         Liabilities (including, for purposes of this section, any other
         consideration paid by Buyer), among the Seller Assets.

                  (ii) Upon receipt of the Allocation Schedule, Seller and its
         independent certified public accountants shall have the right during
         the succeeding thirty (30) day period to review the Allocation
         Schedule and to examine and review all records and work papers and
         other supporting documents used to prepare such schedule. Buyer shall
         give Seller full access at all reasonable times to the working papers
         relating to the Allocation Schedule, including any descriptions of the
         methodology, procedures, internal audits and analysis undertaken in
         connection with the preparation of the Allocation Schedule. Seller
         shall notify Buyer in writing, on or before the last day of the thirty
         (30) day period, of any good faith objections to the Allocation
         Schedule, setting forth a detailed explanation of the objections and
         the dollar amount of each such objection. If Seller does not deliver
         such notice within such thirty (30) day period, the Allocation
         Schedule shall be deemed to have been irrevocably accepted by Seller.

                  (iii) If Seller in good faith objects to line items set forth
         on the Allocation Schedule, the parties shall attempt to resolve any
         such objections within thirty (30) days of receipt by the
         corresponding party of any such objections. If the parties are unable
         to resolve the matter within such thirty (30) day period, they shall
         jointly appoint an Impartial Accounting Firm mutually acceptable to
         the parties (or, if they cannot agree on a mutually acceptable firm,
         they shall cause their respective accounting firms to select such
         firm) within five (5) days after the end of such thirty (30) day
         period to resolve any such remaining matters. Any such resolution
         shall be conclusive and binding on the parties and the fees of the
         Impartial Accounting Firm shall be borne as the Impartial Accounting
         Firm shall determine after considering the positions asserted by the
         parties in light of its final decision. The parties shall fully
         cooperate with the Impartial Accounting Firm. The Impartial Accounting
         Firm shall be instructed to reach its conclusion regarding the dispute
         within thirty (30) days of its appointment to settle the dispute.

                  (iv) Seller and Buyer each agrees to file IRS Form 8594, and
         all federal, state, local and foreign tax returns, in a manner
         consistent with the Allocation Schedule.

         2.4 Limitation on Liabilities of Seller to be Assumed by Buyer.

         Notwithstanding any provision of this Agreement to the contrary, Buyer
shall not assume or become liable to Seller, or any other Person, for any
liabilities or obligations of Seller or any of its Affiliates whether accrued,
absolute, contingent or otherwise, except for those liabilities of Seller and
its Affiliates described on Schedule 2.4 (the "Assumed Liabilities"), which
Buyer hereby assumes and agrees to perform, satisfy and discharge when due.

                                  ARTICLE 3.

                    REPRESENTATIONS AND WARRANTIES BY SELLER

respective terms, subject to applicable bankruptcy, insolvency and similar laws
affecting creditors' rights generally and to the general principles of equity.

         (a) Seller has good and marketable title to the Seller Assets. Except
for (i) the Assumed Liabilities and (ii) Permitted Encumbrances, none of the
Seller Assets shall, at the Closing Date, be subject to any Lien.

         (b) The Seller Assets, in conjunction with the rights, goods and

decree or judgment in progress, pending or in effect, or, to the Knowledge of
Seller, threatened, against or relating to Seller or any of its Affiliates, or
any of their respective members, managers, directors, officers, shareholders,
employees, or properties, in each case, with respect to the Seller Assets or
the Seller Business, which would reasonably be expected to have a material
adverse effect on (a) the Seller Assets or the business, financial condition or
results of operations of the Seller Business, taken as a whole, or (b) the
ability of Seller to consummate the transactions contemplated hereby or perform
any of its obligations hereunder (a "Seller Material Adverse Effect").

         3.6 Compliance with Laws.

         The Seller Business is presently complying in all material respects
with all applicable Laws and Judgments, except for such failures to comply
which, individually or in the aggregate, would not reasonably be expected to
result in a Seller Material Adverse Effect. Seller and its Affiliates have all
Permits necessary for the conduct of the Seller Business as currently
conducted, other than those the absence of which, individually or in the
aggregate, would not reasonably be expected to result in a Seller Material
Adverse Effect, and there are no Proceedings pending, or to the Knowledge of
Seller, threatened which may result in the revocation, termination,
cancellation or suspension of any such Permit except those that, individually
or in the aggregate, would not reasonably be expected to result in a Seller
Material Adverse Effect; it being understood that nothing in this Section 3.6
is intended to address any failure to comply with any Law, Judgment or Permit
(including Environmental Laws or environmentally-related Judgments or Permits)
that is the subject of any other representation or warranty set forth herein.
All of the Seller Permits are listed in Schedule 3.6 of the Seller Disclosure
Schedule, together with any information relative to any requirements applicable
to the assignability of the same.

         3.7 Environmental.

possession, use, occupation, construction and/or improvement to or operation of
the Seller Business on the Seller Real Property, that (i) exists as of the
Closing Date, and (ii) is in violation of applicable Environmental Law as of
the Closing Date or involves concentrations of Hazardous Materials in soils,
surface waters, groundwater, land, stream sediments, or surface or subsurface

2.1(a) and the leased real property upon which a Seller Business Location is
operated.

         (b) Environmental Representations, Warranties, and Obligations. With

applicable to the Seller Real Property and the Seller Business, and no Seller
Environmental Conditions exist that are material, whether individually or in
the aggregate.

under, result in the termination of or a right of termination or cancellation
under, accelerate the performance required by, or result in the creation of any
Lien upon any of the respective properties or assets of Seller or any of its

         6.2 [Omitted]

         6.3 Further Acts.

         (a) Seller shall assist Buyer in planning and accomplishing the
orderly transfer of the Seller Assets to Buyer as of the Closing Date and shall
take all steps reasonably requested by Buyer in furtherance thereof. From time
to time, at the request of Buyer, whether at or after the Closing Date and

execute, acknowledge and deliver to Buyer all further acts, instruments, and
assurances, in recordable form, that are reasonably required by Buyer to
effectuate the terms and conditions of this Agreement and the transactions
contemplated under this Agreement. In addition to the foregoing, on or before
the day which is sixty (60) days following the Closing, Seller shall cause (i)
all of the Seller Required Contractual Consents to be obtained, (ii) the Seller
Permits to be assigned to Buyer, (iii) all certificates of title for all
vehicles/rolling stock being transferred to Buyer as part of the Seller Assets
to be duly executed and assigned to Buyer, and (iv) an Assignment and

commercially reasonable actions necessary at its own cost to clarify, correct,

as to which Buyer may have an objection that affect any parcel of real property
that is conveyed by Seller to Buyer. From time to time, at the request of
Seller, whether at or after the Closing and without further consideration,
Buyer and its officers and employees will do, execute, acknowledge and deliver
to Seller all further acts, instruments, and assurances, in recordable form,
that are reasonably required by Seller to effectuate the terms and conditions
of this Agreement and the assumption of the Assumed Liabilities contemplated

         (b) The agreements of Seller in (a) above shall include, without

         (c) Immediately after the Closing, Seller shall take all actions

         6.4 Consents.

         Notwithstanding anything to the contrary contained in this Agreement,
this Agreement shall not constitute an agreement to transfer, sell or otherwise
assign any instrument, Contract, license or Permit of the Seller Business which
would otherwise be a Seller Asset but which is not permitted to be assigned in
connection with a transaction of the type contemplated by this Agreement
(collectively, the "Unassigned Contracts"). To the extent permitted under the
terms of each Unassigned Contract, the beneficial interest in and to each
Unassigned Contract shall in any event pass to Buyer at the Closing, and Seller
covenants and agrees to cooperate with Buyer in any lawful and economically
reasonable arrangement to provide Buyer with Seller's entire interest in the

shall be responsible for any liability incurred by Seller pursuant to such
direction and, provided, further, that Buyer shall not direct Seller not to
attempt to obtain a Seller Required Contractual Consent for an Unassigned
Contract. If Buyer receives an economic benefit under an Unassigned Contract,
Buyer shall accept the burdens and perform the obligations under such
Unassigned Contract as subcontractor of Seller to the extent of the benefit
received, and to the extent such burdens and obligations would have constituted
an Assumed Liability if such Unassigned Contract had been transferred to Buyer
at the Closing. Furthermore, if the other party(ies) to an Unassigned Contract
subsequently consent to the assignment of such Contract to Buyer, Buyer shall
thereupon agree to assume and perform all liabilities and obligations arising
thereunder after the date of such consent, at which time such Unassigned
Contract shall be deemed a Seller Asset, without the payment of further
consideration, and the obligations so assumed thereunder shall be deemed
Assumed Liabilities.

         6.5 Mail.

         From and after the Closing Date, (i) Buyer may open all mail and other
communications received by Buyer at the Seller Business Locations addressed to
Seller or any of its Affiliates, and may act with respect to such
communications in such manner as Buyer may elect if such communications relate
to the Seller Assets, the Assumed Liabilities or the Seller Business Locations
and the Seller Business (other than payments to which Seller is entitled) or if
such communications do not so relate, Buyer will forward the same promptly to
Seller, and (ii) Seller may open all mail and other communications received by
it with respect to the Seller Business Locations and the Seller Business, and
if such communications relate to the Seller Assets, the Assumed Liabilities or
the Seller Business Locations and the Seller Business (including payments to
which Buyer is entitled), Seller will promptly forward the same to Buyer. Buyer
shall hold, and shall cause its Affiliates, and its and their respective
agents, employees or representatives to hold in strict confidence all documents
and information that are not related to the Seller Assets or the Seller
Business.

         6.6 Post-Closing Assistance.

         From time to time after the Closing and until the fifth (5th)
anniversary of the Closing Date, to the extent permitted by Applicable Law,
Seller shall cause its appropriate employees and representatives (i) to provide
Buyer with information and data (including work papers) reasonably requested by
Buyer which is necessary or useful to Buyer in connection with its current or
former operation of the Seller Business, including personnel and employee
benefit records, or to prepare all accounting and related reports and all tax
returns with respect to the Seller Business, and (ii) to provide Buyer with
assistance as may be reasonably requested by Buyer in connection with its
current or former operation of the Seller Business or any third party claims or
litigation (including any audit or other examination by any taxing authority or
any judicial or administrative proceedings relating to any party's liability
for taxes) with respect to the Seller Business.

         6.7 Confidentiality; Public Announcements.

         Seller and Buyer agree that the terms and conditions of the
transactions contemplated in this Agreement are to remain confidential, except
that a party and its affiliates may disclose the terms and provisions of this
Agreement (i) to the extent that such party or any of its Affiliates is
required by Applicable Law or by the rules of any securities exchange or
trading market to make public disclosure or (ii) in any legal proceeding,
including any audit, to the extent necessary to enforce any rights under this
Agreement, in either case, the disclosing party shall provide the other parties
with prior notice of such disclosure and the content thereof. Any other public
announcement concerning the transactions contemplated by this Agreement,
excepting disclosure in accordance with the provisions of the preceding
sentence, shall be jointly planned and coordinated between Seller and Buyer.
Each party shall provide the other parties with the reasonable opportunity to
review any press release concerning the transactions contemplated by this
Agreement prior to dissemination of such press release.

         6.8 Certain Tax Matters.

         Seller shall prepare and file all returns and reports for its federal,
state and local taxes that are due on or after the Closing Date for the
Business through the Effective Time, including all final employment, security
and sales tax returns. Each of Seller and Buyer shall promptly forward to the
other parties all written notifications and other written communications from
any Governmental Authority received by Seller or Buyer, as the case may be,
relating to any liability for taxes for any taxable period for which the other
parties are obligated under this Agreement.

         6.9 Accounts Receivable.

         In the event that Seller receives any payments subsequent to the
Closing Date relating to any Seller Accounts Receivable outstanding on or after
such date, such payment shall be the property of, and shall be forwarded and
remitted to Buyer as hereinafter provided. After the Closing Date, Seller shall
and shall cause its Affiliates to pay to Buyer on a bi-monthly basis all
amounts received after the Closing Date by Seller with respect to Seller
Accounts Receivable.

         6.10 Discontinuance of Use of Seller Retained Names.

         To the extent any of the Seller Retained Names appear on any plants,
buildings, signs, equipment or other structures that constitute Seller Assets,
Buyer shall, by January 1, 2006, remove or obliterate, or cause to be removed
or obliterated, the Seller Retained Names from such plants, buildings, signs,
equipment or other structures. Seller shall use its commercially reasonable
efforts to remove, or cause to be removed, from the Seller Real Property on or
prior to Closing all stationery, business forms, packaging, containers and
other similar personal property on which any of the Seller Retained Names
appear; provided, however, to the extent any such items are inadvertently left
on the Seller Real Property, Buyer shall not use any such items without first
removing or obliterating, or causing to be removed or obliterated, the Seller
Retained Names from such items. For the avoidance of doubt, except as set forth
in the first sentence of this Section 6.10, Buyer shall have no rights to, and
shall not use in any manner, the Seller Retained Names on or after the Closing.

         6.11 Transition Services.

         Seller shall provide to Buyer the transition services set forth on
Schedule 6.11, pursuant to the terms and subject to the limitations set forth
therein.

         6.12 Like-Kind Exchange.

         (a) Seller may, with respect to some or all of the Seller Assets,
elect to effect a simultaneous or non-simultaneous tax-deferred exchange
pursuant to Section 1031 of the Code and the regulations thereunder. Buyer
expressly agrees to use reasonable efforts to cooperate with Seller, upon
Seller's reasonable request and at Seller's expense, in connection with any
such exchange, including by executing any and all documents, including escrow
instructions or agreements and consenting to Seller's assignment of its rights
hereunder to an exchange entity, which are reasonably necessary to carry out
such an exchange. Any and all representations, obligations, agreements,
warranties and covenants made by Seller to Buyer in connection with this
Agreement shall remain in full force and effect and continue to inure to the
benefit of Buyer, notwithstanding any assignment of this Agreement to a third
party in connection with such Section 1031 exchange. Nothing in this Section
6.12 shall in any manner relieve Seller from any of its obligations under this
Agreement, and Seller shall remain primarily liable to Buyer pursuant to the
terms of this Agreement.

         (b) Buyer's obligation to cooperate in a Section 1031 exchange is
conditioned upon each of the following: (i) Buyer shall not be required to
incur any additional costs, expenses or liabilities (including professional
fees and transfer taxes) as a result of, or in connection with, any action
taken by Buyer under Section 6.12(a) or such Section 1031 exchange, and Seller
shall indemnify and hold Buyer harmless from any cost, expense or liability
incurred by Buyer in connection with any action taken by Buyer under Section
6.12(a) or such Section 1031 exchange, (ii) the Closing shall not be delayed as
a result of such Section 1031 exchange and (iii) all acknowledgments, releases,
representations, warranties, covenants and agreements made by Seller (as set
forth in this Agreement) shall remain in full force and effect in favor of
Buyer as if such Section 1031 exchange had not been made.

         (c) Buyer shall not be in default under this Agreement and shall not
be liable for any damages, losses, costs or expenses incurred by Seller if (i)
any intermediary or exchange entity fails to take any steps to (A) locate,
identify, or negotiate for the acquisition of property, (B) prepare and execute
documents, or (C) arrange for financing necessary to effect the transactions
contemplated by this Section 6.12, (ii) any property designated as such by
Seller fails to qualify as "like-kind" property for purposes of Code Section
1031, or (iii) the transactions described herein otherwise fail, for any
reason, to afford Seller the benefits of Section 1031 of the Code.

         (d) Seller shall be solely responsible for all of the tax incidences
of the transactions contemplated by this Section 6.12, including compliance
with any temporal requirements hereunder or under Code Section 1031 or the
Regulations thereunder.

         6.13 Insurance

         Buyer acknowledges that the Seller Retained Policies will not continue
to insure the Seller Assets or the Seller Business after the Closing Date and
that it is incumbent upon Buyer to obtain substitute policies of insurance that
provide insurance coverage for the Seller Assets and the Seller Business. Buyer
hereby further acknowledges that in the event any casualty or loss, including a
product liability or workers' compensation claim, relating to the Seller Assets
or Seller Business occurs prior to or on the Closing Date, such loss shall be
payable solely from the Seller Retained Policies. Buyer hereby further
acknowledges that in the event any casualty or loss, including a product
liability or workers' compensation claim, relating to the Seller Assets or
Seller Business occurs after the Closing Date, such loss shall be payable
solely from such substitute policies. Any such substitute policies shall
include a waiver of any rights of subrogation that the insurance carriers
underwriting such policies may have against Seller or Seller's Affiliates, or
under the Seller Retained Policies.

         6.14 Office Space

         The parties hereby agree and acknowledge that certain employees of
Seller will remain in the premises located at 1979 Lakeside Parkway Suite 800,
Tucker, Georgia for a period not to exceed 60 days following the Closing Date
and that Seller shall have no obligation to make any payment to Buyer in
respect of rent, utilities, office services or otherwise related to the office
space used by such employees during such 60-day period.

                                  ARTICLE 7.
                                EMPLOYEE MATTERS

         Seller shall transfer, or cause the transfer, to Buyer of the
employees of Seller associated with the Seller Assets and the Seller Business
("Seller Transferred Employees"). Buyer shall maintain, or cause to be
maintained, employee benefit and compensation plans, programs and arrangements
(the "Plans") for the benefit of the Seller Transferred Employees. With respect
to each Plan in which a Seller Transferred Employee participates, for purposes
of determining eligibility, vesting and amount of benefits, including severance
benefits and paid time off entitlement (but not for pension benefit accrual
purposes), Buyer shall cause service with Seller (or predecessor employers to
the extent Seller provided past service credit) to be treated as service with
Buyer and its Affiliates; provided, that such service shall not be recognized
to the extent that such recognition would result in a duplication of benefits
or to the extent that such service was not recognized under an analogous plan
of Seller. With respect to any Plan maintained in which Seller Transferred
Employees are eligible to participate, Buyer shall, and shall cause its
Affiliates to, (i) waive all limitations as to preexisting conditions and
exclusions with respect to participation and coverage requirements applicable
to such employees to the extent such conditions and exclusions were satisfied
or did not apply to such employees under the analogous plan of Seller and (ii)
provide each Seller Transferred Employee with credit for any co-payments and
deductibles paid prior to the Closing Date in satisfying any analogous
deductible or out-of-pocket requirements to the extent applicable under any
such plan. Effective as of the Closing Date, the Seller Transferred Employees
shall cease to participate (and thus shall no longer be eligible for vesting or
benefit accrual under) any employee benefit or compensation plans, programs or
arrangements maintained by Seller.

                                   ARTICLE 8.
                                INDEMNIFICATION

         8.1 Environmental Indemnity.

         Seller, in addition to its other indemnity obligations otherwise
provided in this Article 8, agrees to indemnify and hold harmless Buyer and its
officers, shareholders, members, managers, directors, employees, agents,
successors, and assigns (the "Seller Environmental Indemnitees"), against and
in respect of, any and all Damages and/or claims that may be incurred by any of
the Seller Environmental Indemnitees, or assessed against any of the Seller
Environmental Indemnitees by any other party or parties (including a
governmental entity) arising out of, in connection with, or relating to the
subject matter of: (a) the breach or inaccuracy of any of the representations
and warranties set forth in Section 3.7; (b) any Seller Environmental Condition
which exists as of the Closing Date, even if not discovered until after the
Closing Date, including remediation of such condition and loss of life, injury
to Persons or property, or Damage to natural resources arising from such
condition; (c) any violation of an Environmental Law prior to the Closing Date
that relates to the Seller Real Property or the Seller Business; or (d) the
off-site transportation, storage, disposal, treatment or recycling of Hazardous
Materials generated by or on behalf of the Seller Business on or prior to the
Closing Date, including any claims related to remediation of such Hazardous
Materials and loss of life, injury to Persons or property, or Damage to natural
resources arising from such Hazardous Materials. Such Damages or claims may
sometimes be referred to herein as "Seller Environmental Liabilities." This
indemnity shall survive the Closing Date only for a period of five (5) years
after the Closing Date. Any testing or investigation that Buyer deems
reasonably necessary in order to determine whether any environmental indemnity
obligations of Seller exist hereunder may be conducted at any time prior to the
termination of this indemnity obligation at the expense of Buyer.

         8.2 Indemnity By Seller.

         Subject to the provisions of this Article 8, Seller agrees to pay and
to indemnify fully, hold harmless and defend each Buyer Indemnified Party from
and against any and all claims or Damages arising out of or relating to:

         (a) any inaccuracy or breach of any representation or warranty of
Seller contained in this Agreement;

         (b) any breach of any covenant or agreement of Seller contained in
this Agreement;

         (c) the liabilities and obligations of Seller or any of its Affiliates
arising out of the operation or ownership of the Seller Assets or the Seller
Business on or prior to the Closing Date, except Assumed Liabilities; and

         (d) all obligations or liabilities that arise, whether before, on or
after, the Closing Date, out of, or in connection with, the Retained Seller
Assets;

provided that Seller shall have an obligation to indemnify any Buyer
Indemnified Party for Damages pursuant to this Section 8.2 only to the extent
that such Damages are in excess of (i) any amounts recovered by any Buyer
Indemnified Party pursuant to any contract to which any Buyer Indemnified Party
is a party and (ii) any insurance proceeds received with respect thereto
(exclusive of amounts recovered which are subject to retrospective payments or
premiums); provided, further, that upon making any payment to any Buyer
Indemnified Party, Seller shall be subrogated to all rights of the Buyer
Indemnified Party against any third party in respect of the losses to which
such payment relates, and such Buyer Indemnified Party will execute upon
request all instruments reasonably necessary to evidence and perfect such
subrogation rights. Nothing in this Section 8.2 shall require a Buyer
Indemnified Party to seek to recover Damages from any third party before making
a claim for indemnification pursuant to Article 8.

         8.3 Indemnity by Buyer.

         Subject to the provisions of this Article 8, Buyer agrees to pay and
to indemnify fully, hold harmless and defend each Seller Indemnified Party from
and against any and all claims or Damages arising out of or relating to:

         (a) any inaccuracy or breach of any representation or warranty of
Buyer contained in this Agreement;

         (b) any breach of any covenant or agreement of Buyer contained in this
Agreement; and

         (c) any and all Assumed Liability;

provided that Buyer shall have an obligation to indemnify any Seller
Indemnified Party for Damages pursuant to this Section 8.3 only to the extent
that such Damages are in excess of (i) any amounts recovered by any Seller
Indemnified Party pursuant to any contract to which any Seller Indemnified
Party is a party and (ii) any insurance proceeds received with respect thereto
(exclusive of amounts recovered which are subject to retrospective payments or
premiums); provided, further, that upon making any payment to any Seller
Indemnified Party, Buyer shall be subrogated to all rights of the Seller
Indemnified Party against any third party in respect of the losses to which
such payment relates, and such Seller Indemnified Party will execute upon
request all instruments reasonably necessary to evidence and perfect such
subrogation rights. Nothing in this Section 8.3 shall require a Seller
Indemnified Party to seek to recover Damages from any third party before making
a claim for indemnification pursuant to Article 8.

         8.4 Exclusive Remedy.

         Except as provided in Section 10.12, the right to indemnification
provided for in Sections 8.2 and 8.3 shall be the exclusive remedy of all
Indemnified Parties with respect to the transactions contemplated under this
Agreement.

         8.5 Indemnification Procedures.

         The party or parties making a claim for indemnification under Section
8.1, 8.2 or 8.3 shall be, for the purposes of this Agreement, referred to as
the "Indemnified Party" and the party or parties against whom such claims are
asserted under this Article 8 shall be, for the purposes of this Agreement,
referred to as the "Indemnifying Party." All claims by any Indemnified Party
under this Article 8 shall be asserted and resolved as follows:

         (a) In the event that (i) any claim, demand or Proceeding is asserted
or instituted by any Person other than the parties to this Agreement or their
Affiliates which could give rise to Damages for which an Indemnifying Party
could be liable to an Indemnified Party under this Agreement (such claim,
demand or Proceeding, a "Third Party Claim") or (ii) any Indemnified Party
under this Agreement shall have a claim to be indemnified by any Indemnifying
Party under this Agreement which does not involve a Third Party Claim (such
claim, a "Direct Claim"), the Indemnified Party shall with reasonable
promptness send to the Indemnifying Party a written notice specifying the
nature of such claim, demand or Proceeding and the amount or estimated amount
thereof if known (which amount or estimated amount shall not be conclusive of
the final amount, if any, of such claim, demand or Proceeding) (a "Claim
Notice").

         (b) In the event of a Third Party Claim, the Indemnifying Party shall
be entitled to appoint counsel of the Indemnifying Party's choice at the
expense of the Indemnifying Party to represent the Indemnified Party and any
others the Indemnifying Party may reasonably designate in connection with such
claim, demand or Proceeding (in which case the Indemnifying Party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by any Indemnified Party except as set forth below); provided that
such counsel is reasonably acceptable to the Indemnified Party. Notwithstanding
an Indemnifying Party's election to appoint counsel to represent an Indemnified
Party in connection with a Third Party Claim, an Indemnified Party shall have
the right to employ separate counsel, and the Indemnifying Party shall bear the
reasonable fees, costs and expenses of such separate counsel if (i) the use of
counsel chosen by the Indemnifying Party to represent the Indemnified Party
would present such counsel with a conflict of interest or (ii) the Indemnifying
Party shall not have employed counsel to represent the Indemnified Party within
a reasonable time after notice of the institution of such Third Party Claim. If
requested by the Indemnifying Party, the Indemnified Party agrees to cooperate
with the Indemnifying Party and its counsel in contesting any claim, demand or
Proceeding which the Indemnifying Party defends, or, if appropriate and related
to the claim, demand or Proceeding in question, in making any counterclaim
against the Person asserting the Third Party Claim, or any cross-complaint
against any Person. No Third Party Claim may be settled or compromised (i) by
the Indemnified Party without the prior written consent of the Indemnifying
Party, which consent shall not be unreasonably withheld or delayed or (ii) by
the Indemnifying Party without the prior written consent of the Indemnified
Party, which consent shall not be unreasonably withheld or delayed. In the
event any Indemnified Party settles or compromises or consents to the entry of
any Judgment with respect to any Third Party Claim without the prior written
consent of the Indemnifying Party, each Indemnified Party shall be deemed to
have waived all rights against the Indemnifying Party for indemnification under
this Article 8 with respect to such Third Party Claim.

         (c) In the event of a Direct Claim the Indemnifying Party shall notify
the Indemnified Party within thirty (30) days of receipt of a Claim Notice
whether or not the Indemnifying Party disputes such claim.

         (d) From and after the delivery of a Claim Notice under this
Agreement, at the reasonable request of the Indemnifying Party, each
Indemnified Party shall grant the Indemnifying Party and its representatives
all reasonable access to the books, records and properties of such Indemnified
Party to the extent reasonably related to the matters to which the Claim Notice
relates. All such access shall be granted during normal business hours and
shall be granted under conditions, which will not unreasonably interfere with
the business and operations of such Indemnified Party. The Indemnifying Party
will not, and shall require that its representatives do not, use (except in
connection with such Claim Notice) or disclose to any third person other than
the Indemnifying Party's representatives (except as may be required by
applicable Law) any information obtained pursuant to this Section 8.5(d).

         8.6 Monetary and Payment Limitations.

         (a) Neither Seller nor Buyer shall have any obligation to indemnify a
Buyer Indemnified Party or Seller Indemnified Party pursuant to Sections 8.2(a)
or 8.3(a), respectively, unless the aggregate amount of Damages suffered by all
Buyer Indemnified Parties or Seller Indemnified Parties, as the case may be, in
respect of such claims exceeds $1,000,000, in which case the Buyer Indemnified
Parties or Seller Indemnified Parties, as the case may be, shall be entitled to
recover all Damages including the $1,000,000. For purposes of determining when
and whether the $1,000,000 threshold for indemnification set forth in this
paragraph (a) has been met, the calculation of Damages suffered by an
Indemnified Party in respect of claims pursuant to Sections 8.2(a) or 8.3(a),
as the case may be, shall be deemed to include the aggregate amount of Damages
suffered by all Buyer Indemnified Parties or Seller Indemnified Parties, as the
case may be, and for which claims for indemnification have been made by such
Indemnified Parties pursuant to Section 9.1(a) or Section 9.2(a), as the case
may be, of the Asset and Capital Contribution Agreement dated July 1, 2005, by
and among Ready Mix USA, Inc., CEMEX Holdings LLC and Ready Mix USA, LLC (the
"Ready Mix LLC Contribution Agreement"). For the avoidance of doubt, and by way
of example, in the event that an Indemnified Party suffers Damages (i) in the
amount of $500,000 for which such Indemnified Party would be indemnified under
Section 9.1(a) or Section 9.2(a) of the Ready Mix LLC Contribution Agreement,
as the case may be, but for the limitation provided in Section 9.6(a) of the
Ready Mix LLC Contribution Agreement, and (ii) in the amount of $500,000 for
which such Indemnified Party would be indemnified under Section 8.2(a) or
Section 8.3(a) of this Agreement, as the case may be, but for the limitation
provided in this paragraph (a), then the Indemnified Party shall be entitled to
recover the full $1,000,000 in Damages from the Indemnifying Party.

         (b) Notwithstanding any provision of this Agreement to the contrary,
the aggregate liability of Seller or Buyer for Damages in respect of all claims
for indemnification pursuant to Section 8.2(a) or 8.3(a), respectively, shall
in no event exceed the Purchase Price. NO PARTY SHALL BE LIABLE FOR
CONSEQUENTIAL, INCIDENTAL, SPECIAL, PUNITIVE, OR SIMILAR DAMAGES, EXCEPT TO THE
EXTENT ASSERTED BY, AWARDED, PAID OR PAYABLE TO ANY THIRD PARTY.

         (c) The parties mutually agree that payment to a Buyer Indemnified
Party by Seller for Damages shall be paid solely from the required EBITDA
distributions to be paid to Cemex Holdings LLC or any of its Affiliates
pursuant to Section 6.1 of the Ready Mix LLC Agreement and Section 6.1 of the
Cemex LLC Agreement, as the case may be, and subject to the terms of Section 21
of the Ready Mix LLC Agreement, as amended by the Ready Mix Amendment, and
Section 21 of the Cemex LLC Agreement, as amended by the Cemex LLC Amendment.

         (d) Notwithstanding the foregoing, the Indemnified Party shall not be
limited to recovery of Damages pursuant to clause (c) above with respect to
Damages arising out of or relating to any fraud by Seller or Buyer in
connection with this Agreement, the discussions and negotiations leading up to
this Agreement or the transaction contemplated herein, and each of Seller and
Buyer shall be and remain liable to the other for any Damages arising out of
any such claim or fraud.

         8.7 Survival.

         Except for the representations and warranties in Section 3.2(a), which
shall survive without limit, the representations and warranties of Seller
contained in this Agreement shall survive the Closing Date for the applicable
period set forth in this Section 8.7, and any and all claims and causes of
action for indemnification under this Article 8 arising out of the inaccuracy
or breach of any representation or warranty of Seller must be made prior to the
termination of the applicable survival period set forth in this Section 8.7.
All of the representations and warranties of Seller contained in this Agreement
and any and all claims and causes of action for indemnification under this
Article 8 with respect thereto shall terminate on the second anniversary of the
date of this Agreement; provided that the representations and warranties in
Sections 3.3, 3.6, and 3.19 shall survive until the expiration of the
applicable statute of limitations; provided further that the representations
and warranties in Sections 3.7 shall survive until the fifth anniversary of the
date of this Agreement; it being understood that in the event notice of any
claim for indemnification under Section 8.2(a) shall have been given within the
applicable survival period, the representations and warranties that are the
subject of such indemnification claim shall survive until such time as such
claim is finally resolved.

         8.8 Binding Nature.

         The indemnity obligations imposed under this Article 8 shall be
binding upon the parties hereto and their respective successors and assigns.
Wherever possible, such indemnity obligations shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of these indemnity obligations shall be prohibited by or invalid under such
law, such provision shall be ineffective to the extent of such prohibition or
invalidity without invalidating the remainder of the said indemnity
obligations.

                                  ARTICLE 9.
                                  [Omitted]

investigation or right of investigation, each party has the right to fully rely
upon the respective representations and warranties of each other party
contained in this Agreement.

          systems, provided that in the event Buyer is not allowed access to
          these systems, and to the extent permissible under such preexisting

          systems during the Time Period.
