         action. This Agreement has been duly authorized, executed and delivered
         by it and constitutes its valid and binding obligation, enforceable
         against it in accordance with its terms, subject to bankruptcy,
         insolvency, fraudulent transfer, reorganization, moratorium and similar

         registration, consent or approval of any governmental authority or
         other individual, partnership, corporation, joint stock company,

         "Person") is necessary for the execution, delivery or performance of

         The Transferor has not entered into any agreement, arrangement or other
         understanding (i) granting any option, warrant or right of first
         refusal with respect to the Membership Interest to any Person, (ii)
         restricting its right to sell the Membership Interest to any Person, or

         Membership Interest. It has the absolute and unrestricted right, power
         and capacity to assign and transfer the Membership Interest to the
         Transferees free and clear of any Encumbrances (except for any
         encumbrances created on behalf of the Transferees hereunder). Upon

         5. Covenants of the Transferor and the Company.

                  (a) AMENDMENT TO ORGANIC DOCUMENTS. The Company shall not, and
         the Transferor shall not permit the Company to, directly or indirectly
         amend its articles of organization, operating agreement or other

                  (c) PARTICIPATION IN FUTURE FINANCINGS.

                           (i) From the date hereof until the date that a
                  Transferee no longer holds any Membership Interest in the
                  Company, upon any grant of any additional membership interests
                  in the Company (a "Subsequent Grant"), each Transferee (or its
                  designated assigns) shall have the right to participate in up
                  to an amount of the Subsequent Grant equal to a percentage of
                  the Subsequent Grant equal to the aggregate Membership
                  Interest then held by the Transferees (15% as of the date
                  hereof) on the same terms, conditions and price provided for
                  in the Subsequent Grant.

                           (ii) At least 10 Trading Days prior to the closing of
                  the Subsequent Grant, the Company shall deliver to each
                  Transferee a written notice of its intention to effect a
                  Subsequent Grant (a "Subsequent Grant Notice"). The Subsequent
                  Grant Notice shall describe in reasonable detail the proposed
                  terms of such Subsequent Grant, the amount of proceeds
                  intended to be raised thereunder and the Person or Persons
                  through or with whom such Subsequent Grant is proposed to be
                  effected and shall include a term sheet or similar document
                  relating thereto as an attachment.

                           (iii) Any Transferee desiring to participate in such
                  Subsequent Grant must provide written notice to the Company by
                  not later than 5:30 p.m. (New York City time) on the 10th
                  Trading Day after all of the Transferees have received the
                  Subsequent Grant Notice that the Transferee is willing to
                  participate in the Subsequent Grant, the amount of the
                  Transferee's participation, and that the Transferee has such
                  funds ready,

                                       3
<PAGE>

                  willing, and available for investment on the terms set forth
                  in the Subsequent Grant Notice. If the Company receives no
                  notice from a Transferee as of such 10th Trading Day, such
                  Transferee shall be deemed to have notified the Company that
                  it does not elect to participate.

                           (iv) If by 5:30 p.m. (New York City time) on the 10th
                  Trading Day after all of the Transferees have received the
                  Subsequent Grant Notice, notifications by the Transferees of
                  their willingness to participate in the Subsequent Grant (or
                  to cause their designees to participate) is, in the aggregate,
                  less than the total amount of the Subsequent Grant, then the
                  Company may effect the remaining portion of such Subsequent
                  Grant on the terms and with the Persons set forth in the
                  Subsequent Grant Notice.

                           (v) If by 5:30 p.m. (New York City time) on the 10th
                  Trading Day after all of the Transferees have received the
                  Subsequent Grant Notice, the Company receives responses to a
                  Subsequent Grant Notice from Transferees seeking to purchase
                  more than the aggregate amount of the Subsequent Grant, each
                  such Transferee shall have the right to purchase its Pro Rata
                  Portion (as defined below) of the Subsequent Grant. "Pro Rata
                  Portion" means the ratio of (x) the Membership Interest
                  percentage held by a Transferee participating under this
                  Section 5(b) and (y) the sum of the aggregate percentage
                  Membership Interests held by all Transferees participating
                  under this Section 5(b).

                           (vi) The Company must provide the Transferees with a
                  second Subsequent Grant Notice, and the Transferees will again
                  have the right of participation set forth above in this
                  Section 5(b), if the Subsequent Grant subject to the initial
                  Subsequent Grant Notice is not consummated for any reason on
                  the terms set forth in such Subsequent Grant Notice within 60
                  days after the date of the initial Subsequent Grant Notice.

                  (c) OPERATING AGREEMENT. The Amended and Restated Operating
         Agreement of the Company, dated June 1, 2000, attached hereto as
         Exhibit B, is the operating agreement of the Company in effect as of
         the date hereof ("Operating Agreement"). Except as expressly provided
         for under this Agreement, the terms and conditions of which shall
         supersede, modify and amend the terms of that Operating Agreement, the
         terms and conditions of Operating Agreement shall remain in effect.

                  (d) TRANSFERABILITY OF MEMBERSHIP INTEREST. Subject to
         compliance with any applicable securities laws the Membership Interest
         and all rights thereunder and hereunder are transferable in whole or in
         part. Upon a surrender of any certificate(s) (if any) representing the
         transferred Membership Interest the Company shall execute and deliver a
         new certificate in the name of the assignee or assignees and in the
         denomination or denominations as requested by the transferor, and shall
         issue to transferor a new certificate evidencing the portion of

                                       4
<PAGE>

         the Membership Interest not so assigned and the surrendered certificate
         shall be cancelled. Notwithstanding anything in the Operating Agreement
         to the contrary, the Transferor shall have no option to purchase the
         Membership Interest upon a transfer of all or part of such interest
         hereunder under Section VIII of the Operating Agreement.

                  (e) CONSENT AS MEMBER. The Transferor hereby consents to the
         transfer of the Membership Interest contemplated hereunder and approves
         the admittance of the Transferees as full members of the Company.

                  (f) ADDITIONAL CAPITAL CONTRIBUTIONS. The Transferees shall
         not be subject to any demand for additional capital contributions to
         the Company pursuant to Section 3.2.2 of the Operating Agreement or any
         other provision thereof; provided, however, if a Transferee does not
         participate in any such capital call (or participates for less than its
         share), such Transferee's Membership Interest shall be diluted in
         proportion to the size of the capital call and the fair market value of
         the Company at the time of such capital call; provided, further, in the
         event the Transferee disputes the fair market value of the Company such
         Transferee shall have the right to retain the services of an
         independent third party appraiser at its expense and reasonably
         acceptable to the Company to provide a fair market valuation of the
         Company which shall binding on the parties.

                  (g) TAX LIABILITY DISTRIBUTIONS. Notwithstanding anything in
         the Operating Agreement to the contrary, in the event that a Transferee
         shall incur any tax liability on account of any allocations or
         distributions by the Company, the Company, subject to having the
         available cash, shall promptly (and in any event prior to the date such
         Transferee is required to pay such tax liability) make a cash
         distribution to the Transferees in an amount equal to such tax
         liability based on an assumed combined federal and state tax rate of
         forty percent (40%).

                  (h) MANAGEMENT, FIDUCIARY DUTY AND DUTY OF LOYALTY.

                           (i) NO MANAGEMENT RIGHTS. Notwithstanding anything to
                  the contrary in the Operating Agreement, management of the
                  Company shall not be vested in all of the Class A Members of
                  the Company but shall be vested the holders of a majority of
                  the Class A Members or in a manager appointed by a majority of
                  the Class A Members of the Company.

                           (ii) NO FIDUCIARY DUTY. Notwithstanding anything in
                  the Operating Agreement to the contrary, the Transferees shall
                  have the same status and duty as a limited partner in a
                  partnership and therefore shall not be accountable to the
                  Company or the other members of the Company as a fiduciary.

                  owe no duty of loyalty to the Company or the other members of

                               Pending Litigation

In April, 2006, Arizona Pacific Materials, L.L.C. ("APM") commenced an action
against Copper Basin Railway, Inc. and others in the Superior Court, Pinal
County, State of Arizona. The First Amended Complaint seeks a declaratory
judgment and injunctive relief. The litigation concerns a dispute over
maintaining access to APM's property via a particular road.

There is a railroad line that runs down the border of APM's property. One of the
roads used to access APM's property runs along the side of the railroad line.
The defendant railroad claims that the road infringes upon its railroad
easement. APM has commenced this action for a declaration that it has an
easement relative to this roadway and to prevent the railroad from taking any
action to disrupt access to APM's property. The railroad has counterclaimed for
a declaration of the railroad's rights, ejectment of APM from use of this road,
and rent for alleged wrongful use of this road by APM.

The case is pending without a trial date. Cross motions for summary judgment
have both been denied. The railroad has filed a motion for reconsideration of
the denial of its motion for summary judgment. A finding for the railroad would
make accessing APM's property more difficult but probably not overly
problematic.
