Grande Property;

WITNESSETH, that the parties hereto, in consideration of the mutual promises and
undertakings herein contained, mutually agree as follows:

1.)  SCOPE OF SALE AND PURCHASE OF SILICA: VIM agrees to extract and purchase
     silica from sections of the *** Oro Grande Property identified on Exhibit
     "A" which is attached hereto and incorporated herein by reference (the
     "Silica Land"). The parties acknowledge that although the *** Oro Grande
     Property encompasses more real property than is designated on Exhibit "A"

     between *** and VIM dated October 1, 2001.

2.)  RECLAMATION PLAN AND PERMITTING CONSISTENCY

     The parties acknowledge that they will work cooperatively to bring
     consistency to the reclamation plans and permits, if applicable, for the
     work that VIM performs pursuant to this agreement and its agreement dated
     October 1, 2001. To further this commitment, VIM and TXI shall continue to
     meet with, and work with, the County of San Bernardino to realign the
     boundaries for the reclamation plans depicted on the Exhibit "A" map as
     follows:

     First, VIM shall have the boundaries for the VIM Reclamation Plan for the
     October 1, 2001 Agreement, hereinafter referred to as TXI-I, realigned to
     have the green (TXI#1-A) and yellow (TXT#1-B) shaded areas marked within
     TXI-I expanded to include the blue shaded area correspondently marked
     TXI#1-C. The yellow area marked TXI#1-B is currently in both the VIM and
     TXI Reclamation Plans and the blue TXI#1-C shaded area is not currently a
     part of any reclamation plan. VIM agrees to modify the TXI-I plan with the
     County of San Bernardino to include the blue shaded area TXI#1-C.

     Second, VIM shall have the boundaries for its newly anticipated reclamation
     plan for TXI-II conform to include the area shaded blue on the Exhibit "A"
     and shown as TXI#2-A. The green and yellow areas marked TXI#2-B and TM#2-C
     respectively shall remain within the purview of ***'s current reclamation
     plan (84M-009). VIM will initiate TMI#2 mining in the TXI#2 B and C areas
     and depending on the sequencing of VIM's Atlas Project, VIM may or may not
     pursue the permitting and mining of TXI#2-A.

     All haul roads, (and ingress and egress roads), of every type shall be
     preserved pursuant to the agreements the parties have reached in the past,
     and which are memorialized by their prior written agreements.

3.)  CONDUCT OF OPERATIONS ON *** ORO GRANDE PROPERTY. Notwithstanding anything
     herein to the contrary, VIM and *** each acknowledge that, at all times
     during which VIM is conducting its silica operations and/or associated
     reclamation on the Silica Land pursuant to this Agreement,

     (i)  *** shall be actively conducting its portland cement manufacturing
          operations and related activities on portions of the *** Oro Grande
          Property adjacent to and contiguous with the Silica Land; and

     (ii) The designated daily access to the Silica Land shall be through a
          portion of ***'s manufacturing operations and across roads heavily
          used by *** in its manufacturing operations on the *** Oro Grande
          Property; and

     shall be derived in the following manner: An outside neutral contractor to
     VIM and *** shall be hired to haul three loads; the loads to be loaded by
     VIM. These loads will then be driven across VIM's certified scale, as well
     as ***'s/TXI's certified scale. The net average of the three loads shall
     determine the billing rate. This procedure will be repeated every six
     months. The weight for each load

BLM's determination of the amount of materials that you have taken under the
contract is binding on you. You may appeal this determination as provided in
Section 19.

You are liable for the total purchase price, even if the quantity of materials
you ultimately extract is less than the amount shown above. You may not mine
more than the quantity of materials shown in the contract.

Sec. 3. Payments, title and reapprovals. You may not extract the materials until
you have paid in advance for them in full $_______, or paid the first
installment of $*** (1st and last).

[ ]  If you pay in full in advance, BLM will check this box, and Subsections
     Sec. 3(a) through 3(c) do not apply to your contract. You must pay in full
     for all sales of $2,000 or less.

     (a) If you pay in installments, you MUST pay the first installment before
BLM approves the contract.

     (b) Once you start removing material, you MUST pay each subsequent
installment payment monthly to an amount equal to the value of materials removed
in the previous month. Payment must be made by the 15th following the end of the
month for which you are reporting. You must pay the total purchase price not
later than 60 days before the contract expires.

     (c) The United States will retain the first installment as security for
your full and faithful performance and will apply it to the last installment
required to make the total payment equal to the total price given in Section 2.

     The total purchase price equals the sum of the total quantities removed,
multiplied by their respective unit prices.

     If you are late making an installment payment, you MUST not remove any more
material until you have paid. Removing material you have not paid for is
trespass, and for trespass you MUST pay at triple the appraised unit price, or
at triple the reappraised unit price if BLM has made a reappraisal. To resume
removal operations after you were late making payments, you MUST obtain BLM's
written approval.

your failure to use proper conservation practices. If the damage resulted from
willful or gross negligence, you are liable for triple the appraised value of

the United States within 30 days after receiving a written demand from BLM.

Sec. 15. Extensions of time. BLM may grant you an extension of time in which to
comply with contract provisions under the regulations at 43 CFR 3602.27. For

          The use of these exotic species is in accordance with Executive Order
          11987 -- Exotic organisms, dated May 24, 1977, Sec. 2(d); Where there
          has been a determination that there will be no effect on natural

     directly supervise the work on this project. Alternatively, the purchaser
     may assign and have on the job a competent superintendent who is
     satisfactory to the BLM Authorized Officer, and who has authority to act
     for the purchaser.

13.  Permittee shall notify BLM if a second party is removing material from the
     contract area under permittees contract.

14.  The permittee shall be responsible for controlling all noxious weeds and
     other undesirable invading plant species in the reclaimed area until the
     revegetation activities have been determined to be successful and signed
     off by the BLM authorized officer. The operator shall obtain approval from
     the BLM authorized officer for any and all applications of herbicide,
     including types and quantities. ALL SEED SHALL BE TESTED FOR PURITY,
