         (a) the value assigned to the RMUSA Assets is equal to the sum of

                  (ii) Upon receipt of the Cemex Working Capital Statement,
         RMUSA 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 Cemex Working

         period, of any good faith objections to the Cemex Working Capital
         Statement, setting forth a detailed explanation of the objections and
         the dollar amount of each such objection. If RMUSA does not deliver

         Statement shall be deemed to have been irrevocably accepted by RMUSA
         and the Company.

         Cemex and its independent certified public accountants shall have the

         papers and other supporting documents used to prepare such statement.
         RMUSA shall give Cemex full access at all reasonable times to the
         working papers relating to the RMUSA Working Capital Statement,
         including but not limited to any descriptions of the methodology,
         procedures, internal audits and analysis undertaken in connection with
         the preparation of the RMUSA Working Capital Statement. Cemex shall

         period, of any good faith objections to the RMUSA Working Capital
         Statement, setting forth a detailed explanation of the objections and
         the dollar amount of each such objection. If Cemex does not deliver
         such notice within such 30-day period, the RMUSA Working Capital
         Statement shall be deemed to have been irrevocably accepted by Cemex
         and the Company.

         forth on the Cemex Working Capital Statement, or the RMUSA Working
         Capital Statement, as the case may be, the parties shall attempt to
         resolve any such objections within 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 30 days of its appointment to settle the dispute.

                  (v) Adjustments to the values contemplated in paragraphs (a)
         and (b) of this Section 2.3 shall be made pursuant to the Cemex
         Working Capital Statement and the RMUSA Working Capital Statement,
         after their acceptance by the parties or the resolution of all
         disputes in connection therewith, pursuant to the provisions of this
         paragraph 2.3(c) Upon any adjustment to the RMUSA Value or the Cemex
         Value, as contemplated above, in the event that the sum of RMUSA Value
         under this Agreement and the RMUSA Value under the Ready Mix LLC
         Contribution Agreement, as finally determined (the "Aggregate RMUSA
         Contribution"), is less than the sum of the Cemex Value under this
         Agreement and the Cemex Value under the Ready Mix LLC Contribution
         Agreement, as finally determined (the "Aggregate Cemex Contribution"),
         then within ten (10) days following such final determination RMUSA
         shall make a cash contribution (as part of its Contribution) to Ready
         Mix LLC in an amount equal to such shortfall. In the event the
         Aggregate RMUSA Contribution is greater than the Aggregate Cemex
         Contribution, then within ten (10) days following such final
         determination Cemex shall make a cash contribution (as part of its
         Contribution) to Company in an amount equal to such shortfall.

         (d) In connection with the preparation of the Cemex Working Capital
Statement and the RMUSA Working Capital Statement, each of RMUSA and Cemex
shall be entitled, for a period of thirty (30) days following the Contribution
Date, to conduct a review of Company's physical inventory.

         4.4 Consents. Notwithstanding anything to the contrary contained in

Cemex Business or the RMUSA Business which would otherwise be a Transferred
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 Company at the Closing, and each of Cemex and RMUSA,
as the case may be, covenants and agrees to cooperate with Company in any
lawful and economically reasonable arrangement to provide Company with Cemex's
or RMUSA's, as the case may be, entire interest in the benefits under each of
the Unassigned Contracts. Cemex or RMUSA, as the case may be, shall exercise or
exploit its rights and options under all such Unassigned Contracts referred to

Company shall be responsible for any liability incurred by Cemex or RMUSA, as
the case may be, pursuant to such direction and, provided, further, that
Company shall not direct Cemex or RMUSA, as the case may be, not to attempt to
obtain a Required Contractual Consent for an Unassigned Contract. If Company
receives an economic benefit under an Unassigned Contract, Company shall accept
the burdens and perform the obligations under such Unassigned Contract as
subcontractor of Cemex or RMUSA, as the case may be, 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 Company at the Contribution. Furthermore, if the other
party(ies) to an Unassigned Contract subsequently Consent to the assignment of
such Contract to Company, Company shall thereupon agree to assume and perform
all liabilities and the obligations arising thereunder after the date of such
Consent, at which time such Unassigned Contract shall be deemed a Transferred
Asset, without the payment of further consideration, and the obligations so
assumed thereunder shall be deemed Assumed Liabilities.

or obligations of RMUSA or any of its Affiliates whether accrued, absolute,
contingent or otherwise, except for those liabilities of RMUSA and its

         5.2 Limitation on Liabilities of Cemex to be Assumed by Company.

is a limited liability company duly organized, validly existing and in good
standing under the laws of the State of Delaware, and has the requisite power
and authority to own, lease, and operate its properties and carry on and

validly existing and in good standing under the laws of the State of its
organization, and has the requisite power and authority to own, lease, and
operate the Cemex Assets and the Cemex Business that it is contributing to
Company. Each of the Affiliates of Cemex which are contributing Cemex Assets or
Cemex Business to Company has been duly authorized to do so, and has taken all
necessary actions to transfer such Cemex Assets or Cemex Business to Company.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated herein, have been duly authorized by the Board of
Directors of Cemex. Cemex has taken all actions necessary to authorize it to

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

         7.2 Title to and Sufficiency of Cemex Assets.

Cemex Assets shall, at the Contribution Date, be subject to any Lien.

         (b) The Cemex Assets, in conjunction with the rights, goods and
services granted, transferred or to be performed by Cemex and its Affiliates
and subsidiaries pursuant to this Agreement, constitute all the property, real
and personal, tangible and intangible, necessary for the conduct of the Cemex
Business as it is presently being conducted by Cemex or its Affiliates in all
material respects.

         7.3 Taxes. Cemex will pay and satisfy, or cause to be paid and
satisfied, all property and excise and other tax obligations, penalties and
interest, imposed by any governmental entity either (i) in connection with the

Knowledge of Cemex, threatened, against or relating to Cemex or any of its
Affiliates, or any of their respective directors, officers, shareholders,
employees, or properties, in each case, with respect to the Cemex Assets or the
Cemex Business, which would reasonably be expected to have a material adverse
effect on, the Cemex Assets, the Cemex Business or the transactions

         due, or the acceleration or vesting of any rights to any payment or
         benefits, from Company, Cemex or any of their respective Affiliates to

                  (xvii) Contracts entered into outside of the ordinary course
         of business or which are material to the Cemex Business.

full force and effect in all material respects, (ii) Cemex has no Knowledge of
any material default by any third party under any such Contract which default
has not been cured or waived and which default by any third party would
reasonably be expected to result in a material adverse effect on (i) the Cemex
Assets or the business, financial condition or results of operations of the

Business and Cemex and its Affiliates have all Permits necessary for the
conduct of the Cemex 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 Cemex Material Adverse Effect, and there are no
Proceedings pending, or to the Knowledge of Cemex, 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 Cemex Material Adverse Effect; it being understood that
nothing in this Section 7.6 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 Cemex Permits are
listed in Section 7.6 of the Cemex Disclosure Schedule, together with any

by which they or any of their respective properties or assets may be bound or
affected, except (in the case of clause (y) above) for such violations,

Indemnified Party against any third party in respect of the losses to which

request all instruments reasonably necessary to evidence and perfect such
subrogation rights. Nothing in this Section 9.3 shall require a Contributor
Indemnified Party to seek to recover Damages from any third party before making

         9.4 Exclusive Remedy. Except as provided in Section 10.12, the right
to indemnification provided for in this Article 9 shall be the exclusive remedy
of all Company Indemnified Parties with respect to the transactions
contemplated under this Agreement.

         9.5 Indemnification Procedures. The party or parties making a claim
for indemnification under Section 9.1, 9.2 or 9.3 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 9 shall be, for the
purposes of this Agreement, referred to as the "Indemnifying Party." All claims
by any Indemnified Party under this Article 9 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 9 with respect to such Third Party Claim.

         (c) In the event of a Direct Claim the Indemnifying Party shall notify
the Indemnified Party within 30 days Business 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 9.5(d).

         9.6 Monetary and Payment Limitations.

         (a) Neither Cemex nor RMUSA shall have any obligation to indemnify a
Company Indemnified Party pursuant to Sections 9.1(a) or 9.2(a), respectively,
unless the aggregate amount of Damages suffered by all Company Indemnified
Parties in respect of such claims exceeds $1,000,000, in which case the Company
Indemnified Parties shall be entitled to recover all Damages including the
$1,000,000.

         (b) Notwithstanding any provision of this Agreement to the contrary,
the aggregate liability of Cemex or RMUSA for Damages in respect of all claims
for indemnification pursuant to Sections 9.1(a) or 9.2(a), respectively, shall
in no event exceed the Cemex Value or the RMUSA Value, respectively. 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 an Indemnified Party by
an Indemnifying Party for Damages shall be paid solely from the required EBITDA
distributions to be paid to the Indemnifying Party pursuant to Section 6.1 of
the Cemex LLC Agreement and Section 6.1 of the Ready Mix LLC Agreement. In the
event of Damages, compensation for which is owed to the Indemnified Party by
the Indemnifying Party, the parties mutually agree that the Indemnifying Party
shall waive all rights and title it has to, and shall instruct the Manager of
the Company and the Manager of Ready Mix LLC to make to the Indemnified Party,
distributions due the Indemnifying Party from the Company under Section 6.1 of
the Cemex LLC Agreement or Ready Mix LLC under Section 6.1 of the Ready Mix LLC
Agreement until such time as the Indemnified Party has recouped the amount of
Damages incurred by the Indemnified Party. The provisions and limitations set
forth in this Section 9.6(c) will not apply to any indemnification liability of
the Company pursuant to Section 9.3.

         (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 RMUSA or Cemex in connection
with this Agreement, the discussions and negotiations leading up to this
Agreement or the transaction contemplated herein, and each of RMUSA and Cemex
shall be and remain liable to the other for any Damages arising out of any such
claim or fraud.

         9.7 Survival. Except for the representations and warranties in
Sections 7.2(a) and 8.2(a), which shall survive without limit, the
representations and warranties of Cemex and RMUSA contained in this Agreement
shall survive the Contribution for the applicable period set forth in this
Section 9.7, and any and all claims and causes of action for indemnification
under this Article 9 arising out of the inaccuracy or breach of any
representation or warranty of Cemex or RMUSA must be made prior to the
termination of the applicable survival period set forth in this Section 9.7.
All of the representations and warranties of Cemex and RMUSA contained in this
Agreement and any and all claims and causes of action for indemnification under
this Article 9 with respect thereto shall terminate on the second anniversary
of the date of this Agreement; provided that the representations and warranties
in Sections 7.3, 7.6, 7.19, 8.3, 8.6 and 8.19 shall survive until the
expiration of the applicable statute of limitations; provided further that the
representations and warranties in Sections 7.7 and 8.7 shall survive until the
fifth anniversary of the date of this Agreement and the representations and
warranties in Section 7.20 shall survive until the twentieth anniversary of the
date of this Agreement; it being understood that in the event notice of any
claim for indemnification under Section 9.1(a) or Section 9.2(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.

         9.8 Binding Nature. The indemnity obligations imposed under this
Article 9 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 10

                                 MISCELLANEOUS

         10.1 Reliance Upon Representations and Warranties. The parties

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