stockholders of its approximately 65% equity ownership interest in CXP; and

         WHEREAS, CXP and Centex also entered into a Distribution Agreement
dated as of July 21, 2003 (the "Distribution Agreement") pursuant to which (i)
CXP will pay a cash dividend to all of the holders of CXP's common stock
immediately prior to the reclassification and distribution; (ii) Centex will
distribute all of its holdings of CXP Class B Common Stock and all of its
holdings of CXP's common stock to Centex's stockholders on a pro rata basis; and
(iii) CXP changed its corporate name to Eagle Materials, Inc.; and

         WHEREAS, Eagle and Centex mutually desire to terminate the Predecessor
Agreement; and

         WHEREAS, as a related company of Centex, CXP used certain trademarks in
connection with its business, and the Parties desire to enter into this
Agreement to govern the continued use of those trademarks after the termination
of the Predecessor Agreement and the transactions described above.

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein, and for other good and valuable consideration, receipt of which is
hereby acknowledged, the Parties hereby agree as follows:

non-sublicensable, exclusive, perpetual, and royalty-free license to use the
Centex Materials Marks in connection with its ready-mix concrete and aggregates
operations within the State of Texas, subject to the limitations set forth in
this Agreement. The grant of the license hereunder to the Centex Materials Marks
is non-transferable and non-assignable, except that CM may transfer and/or
assign the license to a Subsidiary that is the surviving company of a merger,
reorganization or consolidation with CM or another Subsidiary of the Eagle
Group. Except as expressly set forth herein, no rights or licenses are granted
to CM by Centex with respect to any other trademark, service mark, and/or trade
name other than the Centex Materials Marks.

         3.2 Ownership. CM acknowledges that Centex owns the Centex Materials
Marks and all rights therein and that nothing in this Agreement shall give CM
any right, title or interest in or to the Centex Materials Marks other than
pursuant to the license granted hereby.

         3.3 No Challenge. CM agrees that it will do nothing inconsistent with
Centex's ownership of the Centex Materials Marks and shall not claim adversely
to Centex, or assist any third party in attempting to claim adversely to Centex,
with regards to such ownership. CM agrees that it will not challenge the title
of Centex to the Centex Materials Marks, oppose any registration thereof, or
challenge the validity of this Agreement or the licenses granted herein.

         3.4 Maintenance. All costs associated with maintaining or renewing the
Centex Materials Marks shall be borne by CM. CM, in its discretion, shall have
the sole authority to decide whether to maintain and renew registrations for the
Centex Materials Marks. At CM's request and cost, Centex shall cooperate with CM
and shall in general take such actions as are necessary to facilitate the
maintenance and renewal of the Centex Materials Marks, including timely
executing all documents necessary to do so, including without limitation powers
of attorney, declarations, and affidavits. CM shall provide Centex any

         (a) CM and Centex acknowledge and agree that Centex is intimately
familiar with CM's abilities and expertise in the manufacture of readymix
concrete and aggregates (including without limitation sand, gravel and other
like material).

         (b) CM agrees that all goods sold under the Centex Materials Marks will
be of high quality, standard and skill. CM and Centex acknowledge and agree that
due to the longstanding close working relationship between them, the fact that
officer(s) of Centex are on Eagle's Board of Directors, and given the high
degree of Centex's familiarity with CM's abilities and expertise in the conduct
of its business, Centex is entitled to rely upon CM's own efforts to control the
quality of the goods and services offered under the Centex Materials Marks.

         (c) Notwithstanding the foregoing, Centex shall have the right to
impose on CM, as necessary, other specifications or requirements not provided
for in this Agreement to ensure the requisite quality standards with respect to
products manufactured or sold by CM that display the Centex Materials Marks.
Further, CM shall, on reasonable request and notice from Centex, make available
to CM samples of goods or materials displaying the Centex Materials Marks.

         3.6 Protection; enforcement.

         (a) CM shall promptly notify Centex of any and all infringements,
imitations, simulations or other illegal use or misuse of the Centex Materials
Marks that come to CM's attention. As the sole owner of the Centex Materials
Marks, Centex shall determine whether to take any action to prevent the
infringement, imitation, simulation or other illegal use or misuse of the Centex
Materials Marks.

         (b) CM shall render Centex all reasonable assistance in connection with
any matter pertaining to the protection, enforcement or infringement of the
Centex Materials Marks, whether in the courts, administrative or quasi-judicial
agencies, or otherwise.

         3.7 Termination. Centex shall have the right to terminate this license

CM of its obligations under this Agreement which remains uncured for thirty (30)
days or more following written notice of such breach from Centex, or (b) CM
abandons the use of the Centex Materials Marks, or provides notice to Centex of
its desire to terminate the license. Upon termination of the license, CM agrees
it shall immediately cease any and all use of the Centex Materials Marks.

Marks in connection with the Eagle Business, and (ii) is transferable and
assignable except to the extent that any such transfer or assignment is
prohibited by the provisions of Section 4.5(b) of that certain Distribution
Agreement between Centex and Eagle dated November 4, 2003. Notwithstanding the
licenses granted herein and any of the provisions hereof, no rights or licenses
are granted to Eagle by Centex with respect to any other trademark, service
mark, and/or trade name other than the Licensed Marks.

         4.2 Ownership. Eagle acknowledges that Centex owns the Licensed Marks
and all rights therein and that nothing in this Agreement shall give Eagle or
the Eagle Group any right, title or interest in or to the Licensed Marks other
than pursuant to the license granted hereby.

         4.3 No Challenge. Eagle agrees that it will do nothing inconsistent
with Centex's ownership of the Licensed Marks and shall not claim adversely to
Centex, or assist any third party in attempting to claim adversely to Centex,
with regards to such ownership. Eagle agrees that it will not challenge the
title of Centex to the Licensed Marks, oppose any registration thereof, or
challenge the validity of this Agreement or the licenses granted herein.

         4.4 Maintenance. All costs associated with maintaining or renewing the
Licensed Marks shall be borne by Eagle. Eagle, in its discretion, shall have the
sole authority to decide whether to maintain and renew registrations for the
Licensed Marks. At Eagle's request and cost, Centex shall cooperate with Eagle
and shall in general take such actions as are necessary to facilitate the
maintenance and renewal of the Licensed Marks, including timely executing all
documents necessary to do so, including without limitation all powers of
attorney, declarations and affidavits. Eagle shall provide Centex any reasonably
required information requested by Centex to facilitate its timely execution of
such documents.

         4.5 No Liens. Centex represents and warrants that the Licensed Marks

Eagle shall have the right to purchase any or all of the right, title and
interest in and to the Licensed Marks for a price to be mutually agreed to
between Eagle and Centex, such price to take into account the fact that Eagle
will already have the perpetual and exclusive right to use, maintain and enforce
the Licensed Marks pursuant to this Agreement.

         4.7 Quality Control.

         (a) Centex and Eagle acknowledge and agree that Centex is intimately

without obtaining the consent or approval of Centex, request that any third
party cease and desist from any unauthorized use or infringement of any of the
Licensed Marks.

         (b) Centex shall render all reasonable assistance to Eagle in
connection with any matter pertaining to the protection, enforcement or
infringement of the Licensed Marks, whether in the courts, administrative or
quasi-judicial agencies, or otherwise.

5. THE EAGLE MARKS
