                         AMCOL International Corporation

                                   ----------

         This SUBSIDIARY GUARANTY AGREEMENT dated as of April 2, 2007 (this
"Guaranty") is entered into on a joint and several basis by each of the
undersigned, together with any entity which may become a party hereto by
execution and delivery of a Guaranty Supplement in substantially the form set
forth as Exhibit A hereto (a "Guaranty Supplement") (which parties are
hereinafter referred to individually as a "Guarantor" and collectively as the
"Guarantors").

                                    RECITALS

         A.    Each Guarantor is a direct or indirect Subsidiary of AMCOL
International Corporation, a corporation organized under the laws of the State
of Delaware (the "Company").

         B.    The Company has entered into a Note Purchase Agreement dated as
of April 2, 2007 (as the same may be amended, supplemented, restated or
otherwise modified from time to time, the "Note Purchase Agreement") between the
Company and each of the institutional investors named on Schedule A attached
thereto (the "2007-A Note Purchasers"), providing for, among other things, the
issue and sale by the Company to the 2007-A Note Purchasers of $75,000,000
aggregate principal amount of its Series 2007-A Guaranteed Senior Notes
consisting of (a) $45,000,000 aggregate principal amount of its Series 2007-A
Adjustable Fixed Rate Guaranteed Senior Notes, Tranche 1, due April 2, 2017 (the
"Tranche 1 Notes") and (b) $30,000,000 aggregate principal amount of its Series
2007-A Adjustable Floating Rate Guaranteed Senior Notes, Tranche 2, due April 2,
2017 (the "Tranche 2 Notes"; the Tranche 2 Notes together with the Tranche 1
Notes are collectively referred to herein as the "Series 2007-A Notes").

         C.    Pursuant to the Note Purchase Agreement, the Company may, from
time to time, issue one or more additional Series (as hereinafter defined) of
its unsecured promissory notes ("Additional Notes," and collectively with the
Series 2007-A Notes, the "Notes") to purchasers ("Additional Purchasers")
pursuant to a supplement (a "Supplement"), provided that the aggregate principal
amount of Additional Notes issued pursuant to Supplements in accordance with the
terms of Section 2.2 of the Note Purchase Agreement shall not exceed
$225,000,000. In connection with the issuance of each Series of Additional
Notes, the Guarantors will execute and deliver a Guaranty Accession Agreement in
the form attached hereto as Exhibit B confirming that such Series of Additional
Notes constitutes Notes hereunder and are entitled to the benefits hereof. The
2007-A Note Purchasers and the Additional Purchasers together with their
respective successors and assigns are collectively referred to herein as the
"Holders."

<PAGE>

         D.    The 2007-A Note Purchasers have required as a condition of their
purchase of the Series 2007-A Notes and it is a condition of each Additional
Purchaser's purchase of Additional Notes that the Company cause each of the
undersigned to enter into this Guaranty and, as set forth in Section 9.9 of the
Note Purchase Agreement, to cause certain other Subsidiaries to enter into a
Guaranty Supplement, and the Company has agreed to cause each of the undersigned
to execute this Guaranty and to cause each such other Subsidiary to execute a
Guaranty Supplement, in each case in order to induce the 2007-A Note Purchasers
and Additional Purchasers to purchase the Notes and thereby benefit the Company
and its Subsidiaries by providing funds to the Company for the purposes
described in Section 5.14 of the Note Purchase Agreement or in the case of any
Additional Notes, for the purposes described in the related Supplement.

         NOW, THEREFORE, as required by Section 4.10 of the Note Purchase
Agreement and in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency whereof are hereby acknowledged, each
Guarantor does hereby covenant and agree, jointly and severally, as follows:

SECTION 1.       DEFINITIONS.

         Capitalized terms used herein shall have the meanings set forth in the
Note Purchase Agreement unless defined herein or the context shall otherwise
require.

SECTION 2.       GUARANTY OF NOTES AND NOTE PURCHASE AGREEMENT.

         (a)   Each Guarantor jointly and severally does hereby irrevocably,
absolutely and unconditionally guarantee unto the Holders: (1) the full and
prompt payment of the principal of, Make-Whole Amount, if any, Prepayment
Premium, if any, Breakage Amount, if any, and interest on the Notes from time to
time outstanding, as and when such payments shall become due and payable whether
by lapse of time, upon redemption or prepayment, by extension or by acceleration
or declaration or otherwise (including, to the extent permitted by applicable
law, interest due on overdue payments of principal, Make-Whole Amount, if any,
Prepayment Premium, if any, Breakage Amount, if any, or interest at the rate set
forth in the Notes) in federal or other immediately available funds of the
United States of America which at the time of payment or demand therefor shall
be legal tender for the payment of public and private debts, (2) the full and
prompt performance and observance by the Company of each and all of the
obligations, covenants and agreements required to be performed or owed by the
Company under the terms of the Notes and the Note Purchase Agreement (including
any Supplement) and (3) the full and prompt payment, upon demand by any Holder
of all reasonable costs and expenses, legal or otherwise (including reasonable
attorneys' fees), if any, as shall have been expended or incurred in the
protection or enforcement of any rights, privileges or liabilities in favor of
the Holders under or in respect of the Notes, the Note Purchase Agreement
(including any Supplement) or under this Guaranty or in any consultation or
action in connection therewith or herewith.

                                       -2-
<PAGE>

         (b)   To the extent that any Guarantor shall make a payment hereunder
(a "Payment") which, taking into account all other Payments previously or
concurrently made by any of the other Guarantors, exceeds the amount which such
Guarantor would otherwise have paid if each Guarantor had paid the aggregate
obligations satisfied by such Payment in the same proportion as such Guarantor's
Allocable Amount (as hereinafter defined) in effect immediately prior to such
Payment bore to the Aggregate Allocable Amount (as hereinafter defined) of all
of the Guarantors in effect immediately prior to the making of such Payment,
then such Guarantor shall be entitled to contribution and indemnification from,
and be reimbursed by, each of the other Guarantors for the amount of such
excess, pro rata based upon their respective Allocable Amounts in effect
immediately prior to such Payment; provided that each Guarantor covenants and
agrees that such right of contribution and indemnification and any and all
claims of such Guarantor against any other Guarantor, any endorser or against
any of their property shall be junior and subordinate in right of payment to the
prior indefeasible final payment in cash in full of all of the Notes and
satisfaction by the Company of its obligations under the Note Purchase Agreement
and under each Supplement and by the Guarantors of their obligations under this
Guaranty and the Guarantors shall not take any action to enforce such right of
contribution and indemnification, and the Guarantors shall not accept any
payment in respect of such right of contribution and indemnification, until all
of the Notes and all amounts payable by the Guarantors hereunder have
indefeasibly been finally paid in cash in full and all of the obligations of the
Company under the Note Purchase Agreement and under each Supplement and of the
Guarantors under this Guaranty have been satisfied

         As of any date of determination, (1) the "Allocable Amount" of any
Guarantor shall be equal to the maximum amount which could then be claimed by
the Holders under this Guaranty without rendering such claim voidable or
avoidable under Section 548 of Chapter 11 of the United States Bankruptcy Code
(11 U.S.C. Sec. 101 et. seq.) or under any applicable state Uniform Fraudulent
Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common
law; and (2) the "Aggregate Allocable Amount" shall be equal to the sum of each
Guarantor's Allocable Amount.

         This clause (b) is intended only to define the relative rights of the
Guarantors, and nothing set forth in this clause (b) is intended to or shall
impair the obligations of the Guarantors, jointly and severally, to pay any
amounts to the Holders as and when the same shall become due and payable in
accordance herewith.

         Each Guarantor acknowledges that the rights of contribution and
indemnification hereunder shall constitute an asset in favor of any Guarantor to
which such contribution and indemnification is owing.

SECTION 3.       GUARANTY OF PAYMENT AND PERFORMANCE.

         This is an irrevocable, absolute and unconditional guarantee of payment
and performance (and not merely of collection) and each Guarantor hereby waives,
to the fullest extent permitted by law, any right to require that any action on
or in respect of any Note or the Note Purchase Agreement (including any
Supplement) be brought against the Company or any other Person or that resort be
had to any direct or indirect security for the Notes or for this Guaranty or any
other remedy. Any Holder may, at its option, proceed hereunder against any
Guarantor in the first instance to collect monies when due, the payment of which
is guaranteed hereby, without first proceeding against the Company or any other
Person and without first resorting to any direct or indirect security for the
Notes or for this Guaranty or any other remedy. The liability of each Guarantor
hereunder shall in no way be affected or impaired by any acceptance by any
Holder of any direct or indirect security for, or other guaranties of, any Debt,
liability or obligation of the Company or any other Person to any Holder or by
any failure, delay, neglect or omission by any Holder to realize upon or protect
any such guarantees, Debt, liability or obligation or any notes or other
instruments evidencing the same or any direct or indirect security therefor or
by any approval, consent, waiver, or other action taken, or omitted to be taken
by any such Holder.

                                       -3-
<PAGE>

         The covenants and agreements on the part of the Guarantors herein
contained shall take effect as joint and several covenants and agreements, and
references to the Guarantors shall take effect as references to each of them and
none of them shall be released from liability hereunder by reason of the
guarantee ceasing to be binding as a continuing security on any other of them.

SECTION 4.       GENERAL PROVISIONS RELATING TO THE GUARANTY.

         (a)   Each Guarantor hereby consents and agrees that any Holder or
Holders from time to time, with or without any further notice to or assent from

         other Guarantor) secondarily or otherwise liable for any Debt,
         liability or obligation of the Company on the Notes, or waive any
         Default or Event of Default with respect thereto, or waive, modify,

         substitute any and all property, of any nature and from whomsoever

         indirect security for the payment or performance of any Debt, liability
         or obligation of the Company or of any other Person (including, without
         limitation, any other Guarantor) secondarily or otherwise liable for
         any Debt, liability or obligation of the Company on the Notes; or

               (3)    settle, adjust or compromise any claim of the Company
         against any other Person (including, without limitation, any other
         Guarantor) secondarily or otherwise liable for any Debt, liability or
         obligation of the Company on the Notes.

         Each Guarantor hereby ratifies and confirms any such extension,
renewal, change, sale, release, waiver, surrender, exchange, modification,
amendment, impairment, substitution, settlement, adjustment or compromise and
that the same shall be binding upon it, and hereby waives, to the fullest extent
permitted by law, any and all defenses, counterclaims or offsets which it might
or could have by reason thereof, it being understood that such Guarantor shall
at all times be bound by this Guaranty and remain liable hereunder.

         (b)   Each Guarantor hereby waives, to the fullest extent permitted by
law:

         the creation, renewal or accrual of any liability of the Company,
         present or future, or of the reliance of such Holders upon this
         Guaranty (it being understood that every Debt, liability and obligation
         described in Section 2 hereof shall conclusively be presumed to have
         been created, contracted or incurred in reliance upon the execution of
         this Guaranty);

         the Note Purchase Agreement or any Supplement thereto;

         Person of the Notes or any other instrument, protest thereof and notice
         of its dishonor to any party thereto and to such Guarantor.

         The obligations of each Guarantor under this Guaranty and the rights of
any Holder to enforce such obligations by any proceedings, whether by action at
law, suit in equity or otherwise, shall not be subject to any reduction,
limitation, impairment or termination, whether by reason of any claim of any
character whatsoever or otherwise and shall not be subject to any defense,
set-off, counterclaim (other than any compulsory counterclaim), recoupment or
termination whatsoever.

the Guarantors and their successors and assigns, and shall remain in full force
and effect irrespective of:

         (d)   All rights of any Holder under this Guaranty shall be considered
to be transferred or assigned at any time or from time to time upon the transfer
of any Note held by such Holder whether with or without the consent of or notice
to the Guarantors under this Guaranty or to the Company.

         (e)   To the extent of any payments made under this Guaranty, the
Guarantors shall be subrogated to the rights of the Holder or Holders upon whose
Notes such payment was made, but each Guarantor covenants and agrees that such
right of subrogation and any and all claims of such Guarantor against the
Company, any endorser or other Guarantor or against any of their respective
properties shall be junior and subordinate in right of payment to the prior
indefeasible final payment in cash in full of all of the Notes and satisfaction
by the Company of its obligations under the Note Purchase Agreement and each
Supplement and by the Guarantors of their obligations under this Guaranty, and
the Guarantors shall not take any action to enforce such right of subrogation,
and the Guarantors shall not accept any payment in respect of such right of
subrogation, until all of the Notes and all amounts payable by the Guarantors
hereunder have indefeasibly been finally paid in cash in full and all of the
obligations of the Company under the Note Purchase Agreement and each Supplement
and of the Guarantors under this Guaranty have been satisfied. Notwithstanding
any right of any Guarantor to ask, demand, sue for, take or receive any payment
from the Company, all rights, Liens and security interests of each Guarantor,
whether now or hereafter arising and howsoever existing, in any assets of the
Company shall be and hereby are subordinated to the rights, if any, of the
Holders in those assets. No Guarantor shall have any right to possession of any
such asset or to foreclose upon any such asset, whether by judicial action or
otherwise, unless and until all of the Notes and the obligations of the Company
under the Note Purchase Agreement shall have been paid in cash in full and
satisfied.

         (f)   Each Guarantor agrees that to the extent the Company or any other
Person makes any payment on any Note, which payment or any part thereof is
subsequently invalidated, voided, declared to be fraudulent or preferential, set
aside, recovered, rescinded or is required to be retained by or repaid to a
trustee, receiver, or any other Person under any bankruptcy code, common law, or
equitable cause, then and to the extent of such payment, the obligation or the
part thereof intended to be satisfied shall be revived and continued in full
force and effect with respect to the Guarantors' obligations hereunder, as if
said payment had not been made. The liability of the Guarantors hereunder shall
not be reduced or discharged, in whole or in part, by any payment to any Holder
from any source that is thereafter paid, returned or refunded in whole or in
part by reason of the assertion of a claim of any kind relating thereto,
including, but not limited to, any claim for breach of contract, breach of
warranty, preference, illegality, invalidity or fraud asserted by any account
debtor or by any other Person.

         (g)   No Holder shall be under any obligation: (1) to marshal any
assets in favor of the Guarantors or in payment of any or all of the liabilities
of the Company under or in respect of the Notes and the Note Purchase Agreement
and each Supplement or the obligations of the Guarantors hereunder or (2) to
pursue any other remedy that the Guarantors may or may not be able to pursue
themselves and that may lighten the Guarantors' burden, any right to which each
Guarantor hereby expressly waives.

         (h)   If an event permitting the acceleration of the maturity of the
principal amount of the Notes shall at any time have occurred and be continuing
and such acceleration shall at such time be prevented or the right of any Holder
to receive any payment under any Note shall at such time be delayed or otherwise
affected by reason of the pendency against the Company of a case or proceeding
under a bankruptcy or insolvency law, each Guarantor agrees that, for purposes
of this Guaranty and its obligations hereunder, the maturity of such principal
amount shall be deemed to have been accelerated with the same effect as if the
Holders had accelerated the same in accordance with the terms of the Note
Purchase Agreement (including any Supplement), and such Guarantor shall
forthwith pay such accelerated principal of, Make-Whole Amount, if any,
Prepayment Premium, if any, Breakage Amount, if any, and interest on the Notes
and any other amounts guaranteed hereunder.

SECTION 5.       REPRESENTATIONS AND WARRANTIES OF THE GUARANTORS.

         Each Guarantor represents and warrants to each Holder that:

         (a)   Such Guarantor is a corporation or other legal entity duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, and is duly qualified as a foreign corporation or
other legal entity and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing would not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on (1) the
business, operations, affairs, financial condition, assets or properties of the
Company and its Restricted Subsidiaries, taken as a whole, (2) the ability of
the Guarantors, taken as a whole, to perform their obligations under this
Guaranty or (3) the validity or enforceability of this Guaranty (herein in this
Section 5, a "Material Adverse Effect"). Such Guarantor has the corporate or
other power and authority to own or hold under lease the properties it purports
to own or hold under lease, to transact the business it transacts and proposes
to transact, to execute and deliver this Guaranty and to perform the provisions
hereof.

         (b)   Each Subsidiary of such Guarantor is a corporation or other legal
entity duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization, and is duly qualified as a foreign corporation
or other legal entity and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. Each
Subsidiary of such Guarantor has the corporate or other power and authority to
own or hold under lease the properties it purports to own or hold under lease
and to transact the business it transacts and proposes to transact.

         (c)   This Guaranty has been duly authorized by all necessary action on
the part of such Guarantor, and this Guaranty constitutes a legal, valid and
binding obligation of such Guarantor enforceable against such Guarantor in
accordance with its terms, except as such enforceability may be limited by (1)
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting the enforcement of creditors' rights generally and (2) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

         (d)   The execution, delivery and performance by such Guarantor of this
Guaranty will not (1) contravene, result in any breach of, or constitute a
default under, or result in the creation of any Lien in respect of any property
of such Guarantor or any of its Subsidiaries under any indenture, mortgage, deed
of trust, loan, purchase or credit agreement, lease, organizational document or
any other agreement or instrument to which such Guarantor or any of its
Subsidiaries is bound or by which such Guarantor or any of its Subsidiaries or
any of their respective properties may be bound or affected, (2) conflict with
or result in a breach of any of the terms, conditions or provisions of any
order, judgment, decree, or ruling of any court, arbitrator or Governmental
Authority applicable to such Guarantor or any of its Subsidiaries or (3) violate
any provision of any statute or other rule or regulation of any Governmental
Authority applicable to such Guarantor or any of its Subsidiaries.

                                       -9-
<PAGE>

         (e)   No consent, approval or authorization of, or registration, filing
or declaration with, any Governmental Authority is required to be made or
obtained by such Guarantor in connection with the execution, delivery or
performance by such Guarantor of this Guaranty.

         (f)   (1) There are no actions, suits or proceedings pending or, to the
knowledge of such Guarantor, threatened against or affecting such Guarantor or
any of its Subsidiaries (that are Restricted Subsidiaries) property of such
Guarantor or any of its Subsidiaries (that are Restricted Subsidiaries) court or
before any arbitrator of any kind or before or by any Governmental Authority
that, individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect.

               (2)    Neither such Guarantor nor any of its Subsidiaries (that
         are Restricted Subsidiaries) is in default under any term of any
         agreement or instrument to which it is a party or by which it is bound,
         or any order, judgment, decree or ruling of any court, arbitrator or
         Governmental Authority or is in violation of any applicable law,
         ordinance, rule or regulation (including, without limitation,
         Environmental Laws, ERISA or the USA Patriot Act) of any Governmental
         Authority, which default or violation, individually or in the
         aggregate, would reasonably be expected to have a Material Adverse
         Effect.

         (g)   Neither such Guarantor nor any of its Subsidiaries (that are
Restricted Subsidiaries) is subject to regulation under the Investment Company
Act of 1940, as amended, the Public Utility Holding Company Act of 2005, as
amended, the ICC Termination Act of 1995, as amended, or the Federal Power Act,
as amended.

         (h)   Such Guarantor is solvent, has capital not unreasonably small in
relation to its business or any contemplated or undertaken transaction and has
assets having a value both at fair valuation and at present fair salable value
greater than the amount required to pay its debts as they become due and greater
than the amount that will be required to pay its probable liability on its
existing debts as they become absolute and matured. Such Guarantor does not
intend to incur, or believe or should have believed that it will incur, debts
beyond its ability to pay such debts as they become due. Such Guarantor will not
be rendered insolvent by the execution and delivery of, and performance of its
obligations under, this Guaranty. Such Guarantor does not intend to hinder,
delay or defraud its creditors by or through the execution and delivery of, or
performance of its obligations under, this Guaranty.

         (i)   The obligations of such Guarantor under this Guaranty rank pari
passu in right of payment with all other unsecured Senior Debt (actual or
contingent) of such Guarantor including, without limitation, all obligations of
such Guarantor under any guaranty of Debt of any other Person.

SECTION 6.       AMENDMENTS, WAIVERS AND CONSENTS.

         (a)   This Guaranty may be amended, and the observance of any term
hereof may be waived (either retroactively or prospectively), with (and only
with) the written consent of each Guarantor and the Required Holders, except
that (1) no amendment or waiver of any of the provisions of Sections 3, 4 or 5,
or any defined term (as it is used therein), will be effective as to any Holder
unless consented to by such Holder in writing, and (2) no such amendment or
waiver may, without the written consent of each Holder, (i) change the
percentage of the principal amount of the Notes the Holders of which are
required to consent to any such amendment or waiver or (ii) amend Section 2 or
this Section 6. No consent of the Holders or the Guarantors shall be required in
connection with the execution and delivery of a Guaranty Supplement or other
addition of any additional Guarantor, and each Guarantor, by its execution and
delivery of this Guaranty (or Guaranty Supplement) consents to the addition of
each additional Guarantor. No consent of the Holders or the Guarantors shall be
required in connection with the issuance and sale of Additional Notes, and each
Guarantor, by its execution and delivery of this Guaranty (or Guaranty
Supplement) consents to the issuance of Additional Notes pursuant to the Note
Purchase Agreement.

         (b)   The Guarantors will provide each Holder (irrespective of the
amount of Notes then owned by it) with sufficient information, sufficiently far
in advance of the date a decision is required, to enable such Holder to make an
informed and considered decision with respect to any proposed amendment, waiver
or consent in respect of any of the provisions hereof. The Guarantors will
deliver executed or true and correct copies of each amendment, waiver or consent
effected pursuant to the provisions of this Section 6 to each Holder promptly
following the date on which it is executed and delivered by, or receives the
consent or approval of, the requisite Holders. The Guarantors will deliver
executed copies of each executed Guaranty Supplement to each Holder promptly
following the date on which it is executed.

         (c)   No Guarantor will directly or indirectly pay or cause to be paid
any remuneration, whether by way of fee or otherwise, or grant any security, to
any Holder as consideration for or as an inducement to the entering into by such
Holder of any waiver or amendment of any of the terms and provisions hereof
unless such remuneration is concurrently paid, or security is concurrently
granted, on the same terms, ratably to each Holder even if such Holder did not
consent to such waiver or amendment.

         (d)   Any amendment or waiver consented to as provided in this Section
6 applies equally to all Holders affected thereby and is binding upon them and
upon each future holder and upon the Guarantors. No such amendment or waiver
will extend to or affect any obligation, covenant or agreement not expressly
amended or waived or impair any right consequent thereon. No course of dealing
between the Guarantors and any Holder nor any delay in exercising any rights
hereunder shall operate as a waiver of any rights of any Holder. As used herein,
the term "this Guaranty" and references thereto shall mean this Guaranty as it
may from time to time be amended or supplemented.

         (e)   Solely for the purpose of determining whether the Holders of the
requisite percentage of the aggregate principal amount of Notes then outstanding
approved or consented to any amendment, waiver or consent to be given under this
Guaranty, Notes directly or indirectly owned by any Guarantor, the Company or
any of their Affiliates shall be deemed not to be outstanding.

SECTION 7.       NOTICES.

         All notices and communications provided for hereunder shall be in
writing and sent (a) by telecopy if the sender on the same day sends a
confirming copy of such notice by a recognized overnight delivery service
(charges prepaid) or (b) by a recognized overnight delivery service (charges
prepaid). Any such notice must be sent:

               (1)    if to a 2007-A Note Purchaser or Additional Purchaser or
         its nominee, to such 2007-A Note Purchaser or Additional Purchaser or
         its nominee at the address specified for such communications in
         Schedule A to the Note Purchase Agreement or Supplement, as
         appropriate, or at such other address as such 2007-A Note Purchaser or
         Additional Purchaser or its nominee shall have specified to any
         Guarantor or the Company in writing,

               (2)    if to any other Holder, to such Holder at such address as
         such Holder shall have specified to any Guarantor or the Company in
         writing, or

               (3)    if to any Guarantor, to such Guarantor c/o the Company at
         its address set forth at the beginning of the Note Purchase Agreement
         to the attention of the Chief Financial Officer or at such other
         address as such Guarantor shall have specified to the Holders in
         writing.

Notices under this Section 7 will be deemed given only when actually received.

SECTION 8.       MISCELLANEOUS.

         (a)   No remedy herein conferred upon or reserved to any Holder is
intended to be exclusive of any other available remedy or remedies, but each and
every such remedy shall be cumulative and shall be in addition to every other
remedy given under this Guaranty now or hereafter existing at law or in equity.
No delay or omission to exercise any right or power accruing upon any default,
omission or failure of performance hereunder shall impair any such right or
power or shall be construed to be a waiver thereof but any such right or power
may be exercised from time to time and as often as may be deemed expedient. In
order to entitle any Holder to exercise any remedy reserved to it under this
Guaranty, it shall not be necessary for such Holder to physically produce its
Note in any proceedings instituted by it or to give any notice, other than such
notice as may be herein expressly required.

         (b)   The Guarantors will pay all sums becoming due under this Guaranty
by the method and at the address specified for such purpose for such Holder, in
the case of a Holder that is a 2007-A Note Purchaser, on Schedule A to the Note
Purchase Agreement, and in the case of a Holder that is an Additional Purchaser,
on Schedule A to the corresponding Supplement or by such other method or at such
other address as any Holder shall have from time to time specified to the
Guarantors or the Company on behalf of the Guarantors in writing for such
purpose, without the presentation or surrender of this Guaranty or any Note.

                                      -12-
<PAGE>

         (c)   Any provision of this Guaranty that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

         (d)   If the whole or any part of this Guaranty shall be now or
hereafter become unenforceable against any one or more of the Guarantors for any
reason whatsoever or if it is not executed by any one or more of the Guarantors,
this Guaranty shall nevertheless be and remain fully binding upon and
enforceable against each other Guarantor as if it had been made and delivered
only by such other Guarantors.

         (e)   This Guaranty shall be binding upon each Guarantor and its
successors and assigns and shall inure to the benefit of each Holder and its
successors and assigns so long as its Notes remain outstanding and unpaid. If
any Guarantor enters into any consolidation or merger, pursuant to which such
Guarantor is not the surviving entity (the "Successor Corporation"), the
Successor Corporation shall execute and deliver to each Holder its assumption of
the due and punctual performance and observance of each covenant and condition
of this Guaranty (pursuant to such agreements and instruments as shall be
reasonably satisfactory to the Required Holders).

         (f)   This Guaranty may be executed in any number of counterparts, each
of which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

         (g)   This Guaranty shall be construed and enforced in accordance with,
and the rights of the parties shall be governed by, the law of the State of New
York excluding choice-of-law principles of the law of such State that would
require the application of the laws of a jurisdiction other than such State.

         (h)   Each Guarantor irrevocably submits to the non-exclusive
jurisdiction of any New York State or federal court sitting in the Borough of
Manhattan, The City of New York, over any suit, action or proceeding arising out
of or relating to this Guaranty. To the fullest extent permitted by applicable
law, each Guarantor irrevocably waives and agrees not to assert, by way of
motion, as a defense or otherwise, any claim that it is not subject to the
jurisdiction of any such court, any objection that it may now or hereafter have
to the laying of the venue of any such suit, action or proceeding brought in any
such court and any claim that any such suit, action or proceeding brought in any
such court has been brought in an inconvenient forum.

         (i)   Each Guarantor consents to process being served by or on behalf
of any Holder in any suit, action or proceeding of the nature referred to in
Section 8(h) by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid, return receipt requested,
to it at its address specified in Section 7 or at such other address of which
such Holder shall then have been notified pursuant to said Section. Each
Guarantor agrees that such service upon receipt (1) shall be deemed in every
respect effective service of process upon it in any such suit, action or
proceeding and (2) shall, to the fullest extent permitted by applicable law, be
taken and held to be valid personal service upon and personal delivery to it.
Notices hereunder shall be conclusively presumed received as evidenced by a
delivery receipt furnished by the United States Postal Service or any reputable
commercial delivery service.

                                      -13-
<PAGE>

         (j)   Nothing in Section 8(h) or 8(i) shall affect the right of any
Holder to serve process in any manner permitted by law, or limit any right that
the Holders may have to bring proceedings against any Guarantor in the courts of
any appropriate jurisdiction or to enforce in any lawful manner a judgment
obtained in one jurisdiction in any other jurisdiction.

         (k)   EACH GUARANTOR HEREBY WAIVES TRIAL BY JURY IN ANY ACTION BROUGHT
ON OR WITH RESPECT TO THIS GUARANTY OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION
HEREWITH.

ARTICLE 5
 OWNERSHIP

          Section
5.1          Ownership
Interests.

	
  
 
  	
  
          
(a)            There
shall be one class of ownership interest in the Company (referred to herein as
the “Shares”) and, except as specifically set forth herein,
each Member shall have the same relative rights, powers, and duties with respect
to its Shares.
 
	
  
 
  	
  
 
  
	
  
 
  	
  

          
(b)            The
Company is authorized to issue Two Thousand (2,000) Shares.
 

          Section
5.2          Transfer of
Shares.

	
   
  	
  

          
(a)            Except
as provided in Section 5.2(b) or 5.2(c), no Member may sell, transfer, assign or
pledge its Shares without the written consent of the other Members.  For
purposes of this Agreement, a transfer of Shares shall include any transfer of a
beneficial interest in the Shares or the granting of any lien or encumbrance on
such Shares.  Any sale, transfer, assignment or pledge of Shares not
permitted by this Article 5 will be void and of no effect.
 
	
  
 
  	
  
 
  
	
  
 
  	
  

          
(b)            A
Member may at any time transfer all, but not less than all, of its Shares to an
Affiliate.  No transfer of Shares in reliance on this Section 5.2(b) will
affect the Members’ rights or obligations under this Agreement, except as
may be approved by the Board of Directors pursuant to Section 6.8.

	
  
 
  	
  
 
  
	
  
 
  	
  

          (c)            At
any time after three (3) years after the date of this Agreement and during the
term of this Agreement, a Member Group may transfer all, but not less than all,
of its Shares to any Person without the prior written consent of the other
Member Group if the transferring Member Group complies with the provisions of
this Section 5.2(c):
 

	
  
 
  	
  
              (i)          The
transferring Member Group shall promptly give written notice (the
“Notice”) to the Member Group of which it is not a member (the
“Other Member Group”) at least sixty (60) days prior to the
closing of the proposed transfer.  The Notice shall describe in reasonable
detail the terms of the proposed transfer including, without limitation, (i) the
number of Shares to be transferred (the “Offer Shares”), (ii)
the date of the proposed transfer, (iii) the price and form of consideration to
be paid, and (iv) the name and address of the prospective transferee.

5

	
  
 
  	
  
              (ii)        Upon
receipt of the Notice, the Other Member Group may elect to purchase all (but not
less than all) of the Offer Shares, exercisable by the members of the Other
Member Group in proportion to their Share ownership or as they may otherwise
agree, at the price and on the terms specified in the Notice by delivering
written notice of such election to the transferring Member Group within thirty
(30) business days after the delivery of the Notice.  If the Other Member
Group elects to purchase the Offer Shares from the transferring Member Group,
the transfer of such Shares shall be consummated on or about the original
proposed closing date set forth in the Notice, which shall not be more than
sixty (60) business days following the receipt of the Notice.  To the
extent the Other Member Group does not elect to purchase the Offer Shares, the
transferring Member Group may consummate the proposed transfer on the terms set
forth in the Notice.  Any transfer not on such terms, or effected more than
one-hundred twenty (120) days following receipt of the Notice, shall not be
permitted by this Section 5.2(c) unless the transferring Member Group again
complies with all of the provisions hereof.
 
	
   
  	
  
 
  
	
  
 
  	
  
              (iii)       This
Section 5.2(c) shall not apply to any transfer effected pursuant to the
provisions of Section 5.2(b).  At any time prior to the closing of any
transfer pursuant to this Section 5.2(c), the Other Member Group may make the
demand under Section 5.3 and the process provided under Section 5.3 shall take
precedence over the process provided in this Section 5.2.
 

	
  
 
  	
  
          (d)        Upon
any transfer of Shares permitted by this Section 5.2, the transferee shall be
admitted as a Member of the Company (and as a Member of the transferring
Member’s Member Group) pursuant to Article 12 only upon executing a joinder
agreement in form and substance acceptable to the Board of Directors pursuant to
which the transferee agrees to become bound by the terms hereof and assume all
of the liabilities of the transferring Member under this Agreement.  Such
transfer or assignment shall not discharge the transferring or assigning Member
or Members from their obligations under this Agreement, unless the
non-transferring or non-assigning Member Group hereto consents to such
discharge.
 

          Section
5.3      Buy-Sell Provision.

	
  
 
  	
  
          (a)         At
any time after three (3) years after the date of this Agreement (or before such
time but only as provided in Section 6.3(f)) and during the term of this
Agreement, any Member Group (the “Terminating Group”) may
demand that the other Member Group (the “Remaining Group”)
either purchase all of the Terminating Group’s Shares, or sell all of its
Shares to the Terminating Group.  Such right shall be exercised by the
Terminating Group by providing written notice to the Remaining Group (the
“Notice”), which Notice shall set forth the cash price and
other terms upon which the Remaining Group shall either (i) sell its Shares to
the Terminating Group (pro rata to the Terminating Group’s Members in
proportion to their share ownership or as the Terminating Group may otherwise
agree) or (ii) purchase the Terminating Group’s Shares (pro rata by the
Remaining Group’s Members in proportion to their Share ownership or as the
Remaining Group may otherwise agree).  In no event shall the cash price
offered by the Terminating Group be less than the price calculated in accordance
with the formula provided on attached Exhibit 5.3.  The Remaining
Group shall elect either to sell its Shares to the Terminating Group or to
purchase the Terminating Group’s Shares within the “Period” (as
defined below); provided that if the Remaining Group shall make no
election within the Period, it shall be deemed to have elected to sell its
Shares to the Terminating Group.  For purposes of this Agreement, the
“Period” means 30 days after the date the Notice is given
pursuant to Section 14.1(c). The closing of any sale of Shares pursuant to this
Section 5.3 shall occur within 60 days after the end of the Period, on a date
specified by the purchasing Remaining Group; provided that if the
Remaining Group desires to finance the purchase of the Shares, it may extend the
closing for up to an additional 15 days (i.e., to 75 days after the end of the
Period) and may condition the closing on its ability to obtain financing. 
If the closing does not occur for failure of the Remaining Group to obtain
financing, such event will be treated as an election by the Remaining Group to
sell its Shares to the Terminating Group.  At the closing, (i) the purchase
price shall be paid in full by cash or by certified or bank check, and (ii) the
selling Member Group shall deliver the certificate(s) for its Shares duly
endorsed for transfer to the purchasing Member Group or accompanied by executed
stock powers endorsed to the applicable purchasing Members; such certificate(s)
shall also be accompanied by any other documents that are necessary to transfer
to the applicable purchasing Members good title to the Shares being
purchased.
 

6

	
  
 
  	
  
          (b)         If
the purchaser of Shares in a transaction under this Section 5.3 defaults in
payment of the purchase price set forth in the Buy-Sell Notice, the seller of
such Shares, by notice to such purchaser within 10 days after such default has
occurred, may terminate the agreement for the sale of the Shares to the
purchaser and the seller, by notice to the purchaser, may elect to purchase, or
designate some other person or entity to purchase, the Shares held by the
purchaser at a price which is 20% lower than the Buy-Sell Price and on the
payment terms set forth therein. If the seller makes such an election, the
transaction must be completed on or before the thirtieth (30th) day after the
seller transmits notice of such election to the purchaser (subject to extension
by mutual agreement of the Terminating Member and the Remaining Member). The
rights of the seller under this Section 5.3 (b) are in addition to any other
rights that it may have under this Agreement or other wise as a result of a
default of the purchaser.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (c)         If
a transaction under this Section 5.3 is to occur, the seller in such transaction
may, upon notice to the purchaser and the Company, require that all financial
obligations of the Company to such seller and its affiliates be satisfied in
connection with such acquisition, whether or not otherwise due and payable. For
this purpose, a financial obligation means any debt of the Company (other than
trade payables in the ordinary course of business and not yet due) and any
contingent obligation in respect of debt of the Company (such as would exist if
the seller guaranteed borrowings by the Company from a third party). Any
outstanding indebtedness for borrowed money shall be satisfied either by payment
from the Company or purchase by the purchaser or its designee of the obligation,
in either case at the outstanding principal amount thereof plus interest accrued
(but unpaid) through the date of payment. A contingent financial obligation
shall be satisfied by a release of the seller or an indemnity or other
arrangement reasonably satisfactory to the seller, including but not limited to
an indemnity any for secondary pension withdrawal liability that may exist on
the part of the seller.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (d)         As
of the closing date of a transaction referred to in this Section 5.3, the seller
in such transaction shall enter into a customary non-competition agreement with
the buyer in such transaction restricting the seller from competing with the
Business within the State of Michigan for a period of five (5) years after such
closing date.
 

7

          Section
5.4          Insolvency

          Notwithstanding any
term or provision in this Article 5 to the contrary, if a Member or a
Member’s direct, indirect or ultimate parent (including, without
limitation, U.S. Concrete, Inc.) becomes unable to pay its debts as they become
due, becomes the subject of a bankruptcy or other insolvency proceeding, makes
an assignment for the benefit of creditors or otherwise seeks protection from
its creditors (the “Insolvent Member”), then (a) the provisions
of Sections 5.2(b) and (c) and Section 5.3 shall no longer apply, (b) the
non-Insolvent Members shall have the right to purchase all or any portion of the
Insolvent Member’s Shares in proportion to their Share ownership of the
non-Insolvent Members or as they may otherwise agree, and (c) the purchase price
of such Shares shall equal the price calculated in accordance with the formula
provided on attached Exhibit 5.3.  The non-Insolvent Member may
exercise its right to purchase by giving the Insolvent Members written notice
specifying the date upon which the such purchase will be consummated.

ARTICLE 6
 BOARD OF DIRECTORS

          Section
6.1           Board of
Directors. 

          All aspects of the
business and affairs of the Company shall be managed, and all decisions
affecting the business and affairs of the Company shall be made, by the Members
through a Board of Directors (the “Board of Directors”). 
The Members, acting through the Board of Directors shall have the right, power
and authority to take any and all actions consistent with the Purposes that are
permitted hereunder and under applicable law.  No Member shall have any
right, power or authority to act (as agent or otherwise) for, or to bind, the
Company in any manner except through the Board of Directors or as otherwise
provided in this Agreement.  

          Section
6.2          Number;
Chairman. 

          The Board of
Directors shall be composed of five (5) representatives (each a
“Representative” and collectively the
“Representatives”).  The USC Group shall have the right to
appoint three (3) representatives to the Board of Directors (the “USC
Representatives”) and the Levy Group shall have the right to appoint
two (2) Representatives to the Board of Directors (the “Levy
Representatives”).  The initial USC Representatives shall be
Michael W. Harlan, Robert D. Hardy and Michael Gentoso.  The initial Levy
Representatives shall be S. Evan Weiner and Dan Mergens.  One
Representative shall serve as Chairman of the Board, who shall be elected by the
Board of Directors.  The Chairman shall not have a separate casting vote
and his sole responsibility shall be to preside at Board Meetings, and to vote
in his capacity as Representative. 

8

          Section
6.3          Meetings.

	
  
 
  	
  
          (a)             Regular
quarterly meetings of the Board of Directors shall be held, without notice and
without the necessity of a written agenda, within 45 days after the beginning of
each fiscal quarter according to an annual schedule prepared and distributed by
the Chairman at least ten business days prior to the first quarterly meeting of
each fiscal year or as otherwise scheduled by the Board, for review of all
significant matters relating to the Company’s business.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)           All
meetings of the Board of Directors shall be held at the principal office of the
Company, or at such other place as shall be designated in a Meeting Notice (as
defined in Section 6.3(d)), at such times as shall be designated from time to
time in a Meeting Notice (as hereinafter defined).  Meetings of the Board
of Directors shall be presided over by a Chairman, to be appointed as set forth
in Section 6.2.  All significant planning and strategy matters relating to
the Company will be brought before the Board of Directors.  No action shall
be taken by the Board of Directors without the affirmative vote of at least a
majority of the Board of Directors present at a meeting duly called and held (in
person or by telephone) at which a quorum is present.  Notwithstanding the
foregoing, any decision of the Company (i) to pursue any USC Member’s
indemnification obligations to the Company or to enforce the Guaranty (as
defined below) or (ii) not to retain the real property (the “Sale
Property”) that is subject to the contractual rights and obligations
summarized in that certain memo from Steve Proto to Cesar Monroy dated June 15,
2003 with respect to the Grand Ledge and Lake Lansing properties upon a
third-party offer to purchase such property (so long as the purchase price of
such property is not above 3,750,000), will require the affirmative vote of the
two Levy Representatives and not a majority of the Board of Directors; provided
that upon a third-party purchase of the Sale Property, BWB, Inc. of Michigan (or
another Member designated by the USC Group) will be entitled to receive the
proceeds of the sale unless the Company has assumed the obligations summarized
in the memo to remit the net proceeds of the sale to the original owners of the
Sale Property.  The attendance (in person or by telephone) of a majority of
the Representatives of the Board of Directors that include at least one USC
Representative and one Levy Representative shall constitute a quorum; provided
that if a Representative does not appear at a meeting (and, if a special
meeting, has been given a Meeting Notice), and the proposed meeting is adjourned
for failure of a quorum, and the same Representative again does not appear (and,
if a special meeting, has been given a Meeting Notice for the rescheduled
meeting), then such Representative shall be deemed present at the rescheduled
meeting for purpose of determining whether a quorum is present. 
Significant Transactions (as defined is Section 6.8) will require the
affirmative vote of a four-fifths (4/5) majority of the Board of
Directors.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (c)           Representatives
on the Board of Directors may participate in any regular or special meeting of
the Board of Directors telephonically or through other similar communications
equipment, as long as all of the Representatives participating in the meeting
can hear one another.  Participation in a meeting pursuant to the preceding
sentence shall constitute presence in person at such meeting for all purposes of
this Agreement.
 

9

	
  
 
  	
  
          (d)           Any
Representative may call a special meeting of the Board of Directors upon at
least three (3) business days prior written notice (the ‘‘Meeting
Notice”), which Meeting Notice shall be given no more than thirty (30)
days before the proposed meeting date, and which shall include a proposed agenda
for the meeting.  The requirement of a Meeting Notice may be waived by a
Representative in writing or by attendance (unless such attendance is solely for
the purpose of objecting to the failure to provide a Meeting Notice). 
Additional matters may be added to the proposed agenda for any special meeting
by any Representative upon written notice to the other Representatives, provided
such notice is given at least three (3) business days before the proposed
special meeting, or such lesser period that is affirmatively agreed to by a
majority of the Representatives.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (e)           Any
action required or permitted to be taken at a regular or special meeting of the
Board of Directors may be taken without a meeting by unanimous written consent,
which consent shall set forth the actions to be so taken.  Any such writing
or writings shall be filed with the minutes of the proceedings of the Board of
Directors.  Any such unanimous written consent shall be the approval of the
Board of Directors as if such action was taken at a properly called and
constituted meeting of the Board of Directors at which all of the
Representatives were present and voting.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (f)            In
the event of a disagreement among the Board of Directors or the Members
regarding any dispute wherein (i) the solvency of the Company would be
reasonably expected to be threatened, or (ii) the ability of the Company to
operate as a going concern would reasonably be expected to be materially
adversely affected (any such disagreement being referred to herein as a
“Dispute”), the Members shall negotiate in good faith to

right of the Company) to which any such Person may be made a party by reason of
the fact that such person was a Representative, an officer, a Member or an
employee, representative, Affiliate, director, member, manager or officer of a
Member.  In any situation in which such indemnification or advancement of
expenses is authorized, permitted or required by or under the Act, the
obligations of the Company to indemnify and advance expenses shall be mandatory,
but such obligation shall only be enforceable against the assets of the

ARTICLE 7
 OFFICERS

          Section
7.1          Officers.

	
  
 
  	
  
          (a)             The
Board of Directors may appoint such officers at such time, for such term, with
such power and authority and for such compensation and other benefits (if any),
all as the Board of Directors shall determine in its discretion.  The
officers of the Company shall initially include a President, Secretary and a
Treasurer.  Each such officer shall hold office for the term for which such
officer is appointed.  Any individual may hold any number of
offices.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (b)             Subject
to applicable law and any applicable contractual relationships, officers may be
removed at any time with or without cause by the Board of Directors.

	
  
 
  	
  
 
  
	
  
 
  	
  
          (c)             Each

ARTICLE 8
 CAPITAL CONTRIBUTIONS, DISTRIBUTIONS, SPECIAL PAYMENT
OBLIGATION

          Section
8.1          Capital
Contributions. 

          Contemporaneously
with the execution of this Agreement and pursuant to the terms of the
Contribution Agreement, the parties hereto are making contributions to the
capital of the Company and being issued Shares as set forth on Exhibit A
attached hereto and are hereby admitted to the Company as Members.

          Section
8.2          Additional
Contributions. 

	
  
 
  	
  
          (a)            The
Members may, but shall not be required to, make additional capital contributions
to the Company.  If the Board of Directors determines that the Company
requires additional capital, the Members will be requested to make additional
capital contributions in proportion to their Share ownership.  If either
Member Group does not provide such funding, the other Member Group may, but is
not required to, contribute the shortfall, exercised by the Members of such
Member Group in proportion to their Share ownership or as they may otherwise
agree.  After all additional capital is contributed, additional Shares
shall be authorized and issued to the Members as necessary so that the Shares
held by each Member shall be proportional to each Members aggregate capital
contributions as a fraction of the total aggregate capital contributions of all
Members; provided, however, the Member Group contributing such funding may,
instead of providing such funding in exchange for additional Shares, elect to
provide such funding to the Company in the form of a convertible loan facility
on terms and conditions satisfactory to such Member Group and the Board of
Directors.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)            Notwithstanding
any term or provision in this Agreement to the contrary, each Member shall have
the right to contribute additional assets located in Michigan relating to the
Business in exchange for additional Shares.  In no event, however, shall
such contributing Member’s ownership interest in the Company exceed
60%.
 

13

          Section
8.3          Status of
Capital Contributions.

	
  
 
  	
  
          (a)             No
Member shall be entitled to demand the return of its capital contributions prior
to the dissolution and winding-up of the Company.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)             The
Members shall not receive any interest, salary or draw with respect to their
capital contributions or for services rendered to or on behalf of the Company or
otherwise in their capacity as Members, except as otherwise specifically agreed
in a writing executed by all Members.
 

          Section
8.4          Distributions.

	
   
  	
  
          (a)             Distributions
shall be made to the Members at the times and in the aggregate amounts
determined by the Board of Directors.  Any distributions shall be made in
the following manner and order of priority:
 

	
  
 
  	
  
                 (i)          First,
to the Members to the extent of any Undistributed Profits allocated to them, in
the order of priority allocated to them (i.e., distribution of Undistributed
Profits on a “first in, first out” basis); and
 
	
  
 
  	
  
 
  
	
  
 
  	
  
                 (ii)        Then,
to the Members pro rata, in accordance with their Shares.
 

	
  
 
  	
  
          (b)             Notwithstanding
the foregoing, the Company shall make minimum distributions to each Member
during or as soon as practicable following the end of each fiscal year in an
amount equal to the taxable income allocated to such Member under Section 9.3
for such fiscal year multiplied by the highest marginal tax rates applicable to
individuals residing in the State of Michigan, provided such minimum
distributions shall be treated as advances of future distributions otherwise
required by this Section 8.4(a).
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (c)             Notwithstanding
any provision to the contrary contained in this Agreement, the Company shall not
make a distribution to a Member if (i) such distribution would cause the Company
to be in default under or in violation of any agreement, (ii) after such
distribution the Company would not have sufficient cash to operate its business
or (iii) such distribution would violate Section 307 of the Act or other
applicable law.

ARTICLE 9
 ALLOCATIONS; CAPITAL ACCOUNTS

          Section
9.1          Allocation of
Profits and Losses.   

	
  
 
  	
  
          (a)             The
Company’s profit or loss for each fiscal year shall be determined in
accordance with generally accepted accounting principles as applied in the
United States, provided, however, that in no event shall any expense or loss
which is reimbursed or reimbursable to the Company, or against which the Company
is indemnified, by any Member or Affiliate of a Member pursuant to this
Agreement or any other agreement to which such Member or Affiliate is a party be
taken into account (but, rather, any such loss or expense shall be disregarded)
in determining such profit or loss.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)             Subject
to Sections 9.1(e) and 9.1(f) below, profit for each fiscal year, determined in
accordance with Section 9.1(a), shall be allocated between the Members as
follows:
 

	
  
 
  	
  
                 (i)          the
first $2,100,000 of profit for the fiscal year ending December 31, 2007, shall
be allocated to the members of the USC Group pro rata based upon their Shares,
and the balance of the profit for such fiscal year shall be allocated among the
Members pro rata based upon their Shares;
 
	
   
  	
  
 
  
	
  
 
  	
  
                 (ii)         profit
for any subsequent fiscal year shall be allocated first, pro rata, in proportion
to and to the extent of (so as to offset) any losses allocated pursuant to
Section 9.1(c) below in any prior fiscal year, in reverse of the order that such
losses were allocated, and the balance of any such profits shall be allocated as
follows:
 

	
  
 
  	
  
 
  	
  
               (A)          the
balance of any such profit for the first year ending December 31, 2008, shall be
allocated first to the members of the USC Group (pro rata based upon their
Shares) to the extent, and up to the amount, of $750,000, and any remaining
profit for such fiscal year shall be allocated among the Members pro rata based
on their Shares;
 
	
  
 
  	
  
 
  	
  
 
  
	
   
  	
  
 
  	
  
               (B)          the
balance of any such profit for the fiscal year ending December 31, 2009, shall
be allocated first to the members of the USC Group (pro rata based upon their
Shares) to the extent, and up to the amount, of $750,000, and any remaining
profit for such fiscal year shall be allocated among the Members pro rata based
on their Shares; and
 
	
  
 
  	
  
 
  	
  
 
  
	
  
 
  	
  
 
  	
  
               (C)          the
balance of any such profit for any subsequent fiscal year shall be allocated
among the Members pro rata based on their Shares.
 

	
  
 
  	
  
          (c)             Subject
to Sections 9.1(e) and 9.1(f) below, loss for each fiscal year, determined in
accordance with Section 9.1(a), shall be allocated among the Members as
follows:
 

	
  
 
  	
  
                (i)          First,
pro rata, in proportion to and to the extent of (so as to offset) any
Undistributed Profits from any prior fiscal year(s), in reverse of the order
that such Undistributed Profits were allocated, and
 
	
  
 
  	
  
 
  
	
  
 
  	
  
                (ii)         the
balance of any losses shall be allocated between the Members pro rata, based on
their Shares.
 

15

	
  
 
  	
  
          (d)          To
the extent that any profit is allocated so as to offset any loss (or vice
versa), such profit and loss shall be disregarded for purposes of thereafter
applying the provisions of this Section 9.1 and those of Section 8.4 and in the
definition of Undistributed Profits.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (e)             The
parties anticipate that the Company will (directly or through one or more of the
Superior Subsidiaries) earn rebates pursuant that certain Cement Rebate
Agreement of even date, and that such rebates will generally be taken into
account in determining the Company’s annual profit or loss.  In
applying the provisions of Sections 9.1(b)(i) and 9.1(b)(ii)(A) and (B),
however, the parties intend that such rebates be allocated among the Members
based on their Shares before the balance of any profit is allocated.  For
example,
 

	
  
 
  	
  
 
  	
  
(i)          if for the fiscal
year ending December 31, 2007, such rebates amount to $400,000, and total profit
(determined before taking such rebates into account) is $1,700,000, then (A)
$1,700,000 (rather than $2,100,00) of profit would be allocated to the members
of the USC Group (pro rata based upon their Shares), (B) the balance of the
profit (i.e., the $400,000 of rebates) would be allocated among all of the
Members based on their Shares, and (C) Levy would be required to make a payment
to the USC Group of $160,000 pursuant to Section 9.1(g) below, but would be
entitled to a distribution of $160,000 at such time as the Undistributed Profits
for such fiscal year were distributed, and
 
	
   
  	
  
 
  	
  
 
  
	
  
 
  	
  
 
  	
  
(ii)          if for the
fiscal year ending December 31, 2008, such rebates amount to $400,000, and total
profit (determined before taking such rebates into account) is $350,000, then
$350,000 (rather than $750,00) of profit would be allocated to the members of
the USC Group (pro rata based upon their Shares), and the balance of the profit
(i.e., the $400,000 of rebates) would be allocated among all of the Members
based on their Shares.
 

	
  
 
  	
  
          (f)          In
the event that any goodwill contributed by a Member is impaired, any deduction
from or charge against profit or loss for such impairment shall be specially
allocated to such Member, and such allocation shall (on a dollar for dollar
basis) decrease the profit, or increase the loss, which would otherwise be
allocated to such Member.  For example, if a USC Member were to contribute
$3 million of goodwill, and such goodwill were to become completely impaired in
a subsequent year for which the profit allocable to such USC Member (determined
before the application of this paragraph) were $3 million, then such USC Member
would be allocated no profit (or loss) for such fiscal year.  No deduction
for impairment allocated to any USC Member shall be taken into account, however,
for purposes of applying the provisions of Section (g) below and; accordingly,
no such deduction shall give rise to (or increase) any obligation of Levy to
make a payment to such USC Member pursuant to Section 9.1(g) below.  In
addition, the parties acknowledge that the USC Group is contributing, among
other assets, prepaid licenses for certain vehicles which may, in the hands of
the Company or a Superior Subsidiary, have to be re-licensed.  If, by
reason of the re-licensing of any such vehicles or for any other reason, the
prepaid licenses contributed by the USC Group become impaired, worthless or the
like, then any resulting deduction from or charge against profit or loss shall
be specially allocated to the USC Group, and such allocation shall (on a dollar
for dollar basis) decrease the profit, or increase the loss, which would
otherwise be allocated to the USC Group (but, as with any deduction for
impairment of goodwill specially allocated to the USC Group, any deduction or
charge for impairment, worthlessness or the like of any such prepaid license
shall not be taken into account for purposes of applying the provisions of
Section (g) below and; accordingly, shall not give rise to (or increase) any
obligation of Levy to make a payment to the USC Group (or any USC Member)
pursuant to Section 9.1(g) below).
 

16

	
  
 
  	
  
          (g)             In
the event that the aggregate allocation of profit of the Company to the USC
Group for the Company’s fiscal year ending December 31, 2007, is less than
$2,100,000, Levy agrees to pay the USC Group (pro rata to the USC Members in
proportion to their respective Share ownership) an amount equal to the lesser of
(i) forty (40%) percent of the difference between $2,100,000 and the amount of
profit allocated to the USC Group for such fiscal year and (ii) $840,000. 
Any such payment shall be treated, for federal income tax purposes, as a
contribution by Levy to the Company’s capital and a guaranteed payment by
the Company to the USC Group for the use of capital within the meaning of
Section 707(c) of the Code, the deduction for which shall be allocated to Levy
for such tax purposes.  There shall be no net credit or debit to
Levy’s capital account on account of such payment (and/or on account of any
deemed contribution and deduction resulting therefrom), which shall be
disregarded in determining profit or loss under this Section 9.1.  Such
payment will be made within 60 days after the end of the fiscal year.

          Section
9.2          Capital
Accounts.

	
   
  	
  
          (a)             The
Company shall maintain for each Member a capital account to which such
Member’s capital contributions, and any profits allocated to such Member,
shall be credited, and against which distributions to such Member, and any
losses allocated to such Member, shall be charged.  The profits and losses
to be taken into account in maintaining the Members’ respective capital
accounts shall be determined in accordance with Section 9.1 above.

	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)             No
Member shall have any obligation to restore any negative balance in such
Member’s capital account.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
Section   9.3          Allocations   Solely for Tax Purposes.
  
	
  
 
  	
  
 
  
	
  
 
  	
  
          (a)             Each
item of income, gain, loss or deduction entering into the computation of the
Company’s profit and loss as determined for federal income tax purposes
shall be allocated among the Members in the same proportions as the
corresponding items are allocated for capital accounting (“book”)
purposes, except as provided below in this Section 9.3.
 
	
   
  	
  
 
  
	
  
 
  	
  

          (b)             Income,
gain, loss and deduction with respect to any property (other than cash)
contributed to the capital of the Company shall, solely for tax purposes, be
allocated among the Members so as to take account of any variation between the
adjusted basis to the Company of the property for federal income tax purposes
and such property’s fair market value at the time of such contribution in
the following manner, or in such other manner as the Board may choose.  Any
depreciation or amortization for income tax purposes of any asset contributed by
a Member shall be allocated to such Member and, on sale or other taxable
disposition of any such asset, (i) gain shall be allocated to such Member except
to the extent that the “amount realized” (within the meaning of
Section 1.1001-1(a) of the Treasury Regulations) on such sale or other
disposition exceeds the fair market value of such asset at the time of
contribution to the Company and (ii) loss shall be allocated to such Member
except to the extent that the fair market value of such asset at the time of

Service of Process.  Legal proceedings commenced by any party hereto
arising out of any of the transactions or obligations contemplated by this
Agreement shall be brought exclusively in the federal court in Detroit,
Michigan, or in the absence of federal jurisdiction in Oakland County Circuit
Court in Michigan.  The parties hereto irrevocably and unconditionally
submit to the jurisdiction of such courts and agree to take any and all future
action necessary to submit to the jurisdiction of such courts.  The parties
hereto irrevocably waive any objection that they now have or hereafter may have
to the venue of any suit, action or proceeding brought in any such court and
further irrevocably waive any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.  Final
non-appealable judgment against any party hereto in any such suit, action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment, a certified or true copy of which shall be conclusive
evidence of the fact and the amount of any indebtedness or liability of the
party therein described, or by appropriate proceedings under any applicable
treaty or otherwise.
 
	
  
 
  	
  
 
  
	
   
  	
  
          (b)              Governing
Law.  This Agreement shall be governed by and construed and enforced in
accordance with the internal laws of the State of Michigan, without giving
effect to conflicts of law principals.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (c)              Notices.

interest, or their permitted assignees at the addresses set forth on the

          (d) 
              Assignment. 
Except as otherwise provided in Section 5.2 and this Section 14.1(d), neither
party hereto will transfer or assign any right, obligation or remedy under this

obligation or remedy under this Agreement to an Affiliate under common control
with such party hereto provided that, at the time of such transfer, the
transferee shall agree in writing to be bound by all applicable terms of this
Agreement; provided, however, that such transfer or assignment shall not
discharge the transferring or assigning party from its obligations under this
Agreement unless the non-transferring or non-assigning party hereto consents to
such transfer or assignment. No transfer or assignment in reliance on this
Section 14.1(d) will affect the parties’ rights or obligations under this
Agreement, except as may be otherwise agreed by the parties in
writing.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (e)
               Complete
Agreement, Amendments and Waiver.  This Agreement constitutes the
entire agreement of the parties hereto with respect to the transactions
contemplated herein and shall supersede all previous oral and written and all
contemporaneous oral negotiations, commitments, and understandings.  This
Agreement may be modified only by a written instrument duly executed by each
party hereto.  Except as herein expressly provided to the contrary, no
breach of any covenant or agreement contained herein shall be deemed waived
unless expressly waived in writing by the party that might assert such
breach.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (f) 
              Counterparts. 
This Agreement may be executed in one or more counterparts, each of which shall
be deemed an original, and all of which together shall constitute one and the
same instrument.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (g) 
              Headings. 
Headings in this Agreement are for reference purposes only and shall not be
deemed to have any substantive effect.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (h) 
              Attorneys’
Fees.  In the event that any action or proceeding, including
arbitration, is commenced by any party hereto for the purpose of enforcing any
provision of this Agreement, the parties to such action, proceeding or
arbitration may receive as part of any award, judgment, decision or other
resolution of such action, proceeding or arbitration their costs and reasonable
attorneys’ fees as determined by the person or body making such award,
judgment, decision or resolution.  Should any claim hereunder be settled
short of the commencement of any such action or proceeding, including
arbitration, the parties in such settlement shall be entitled to include as part
of the damages alleged to have been incurred reasonable costs of attorneys or
other professionals in investigating or counseling on such claim.

	
  
 
  	
  
 
  
	
  
 
  	
  
          (i) 
              Severability. 
Any provision of this Agreement which is invalid, illegal or unenforceable in
any jurisdiction will, as to that jurisdiction, be ineffective to the extent of
such invalidity, illegality or unenforceability, without affecting in any way
the remaining provisions hereof in such jurisdiction or rendering that or any
other provision of this Agreement invalid, illegal or unenforceable in any other
jurisdiction.

          (j) 
              Third
Parties.  Nothing in this Agreement, express or implied, is intended to
confer upon any party, other than the parties hereto and their respective
successors and permitted assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (k) 
             Drafting
Presumption. The parties hereto agree that they participated in the drafting
of this Agreement and, in the event that any dispute arises in the
interpretation or construction of this Agreement, no presumption shall arise

          Section
14.2          Necessary
Actions. 

          Subject to
applicable law, the Members will act in such a manner as may be necessary to
give effect to the provisions of this Agreement.

          Section
14.3        Access to
Information.

	
  
 
  	
  
          (a)            Except
as necessary to comply with applicable law or contract, and subject to any
applicable privileges (including the attorney-client privilege), each Member
shall, upon reasonable prior notice, be given reasonable access to the
Company’s employees, agents, properties, books and records during normal
business hours.  The Company will prepare and deliver such financial or
other information concerning its business as either Member may reasonably
request.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)            The
Company will furnish to each Member, upon request, as promptly as practicable,
such information and assistance as is reasonably necessary for the filing of
each Member’s tax returns, the making of any election related to taxes, the
preparation for any audit by any tax authority, and the prosecution or defense
of any claim, suit or proceeding relating to any tax return.
 

          Section
14.4          Freedom of
Action. 

          Except as set forth
in Sections 14.5 and 14.6, each Member and its Affiliates (for the purposes of
this Section 14.4, each a “Permitted Person”) may have other
business interests and may engage in any other business or trade, profession or
employment whatsoever, on its own account, or in partnership with, or as an
employee, officer, director or stockholder of, any other person or entity. 
Except as set forth in Sections 14.5 and 14.6, neither the Company nor any
Member or Affiliate thereof shall have any rights by virtue of this Agreement in
and to any such venture or the income or profits derived therefrom, regardless
of whether or not such venture was presented to a Permitted Person as a direct
or indirect result of such Permitted Person’s connection with the
Company.  Except as set forth in Sections 14.5 and 14.6, no Permitted
Person shall have any obligation to present any business opportunity to the
Company and no Permitted Person shall be liable to the Company, any Member or
any Affiliate thereof for breach of any fiduciary or other duty, as a Member or
otherwise, by reason of the fact that such Permitted Person pursues or acquires
any such business opportunity, directs such business opportunity to another
person or entity or fails to present such business opportunity, or information
regarding such business opportunity, to the Company.

22

          Section
14.5          Company
Opportunities. 

	
  
 
  	
  
          (a)
               The
Company and each Member shall have the rights set forth in this Section 14.5
with respect to Company Opportunities.  Neither the Company nor any Member
or Affiliate thereof shall take any actions with respect to a Company
Opportunity except in compliance with this Section 14.5.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)
               In
the event that any Member or its Affiliates become aware of a Company
Opportunity (other than an Ancillary Transaction, as defined in Section 14.5(c))
that such Member or such Member’s Affiliate desires to pursue, such Member
(the “Proposing Member”) shall notify the Member Group of which
it is not a member (the “Deciding Member Group”) in writing (an
“Opportunity Notice”) thereof. Upon delivery of the Opportunity
Notice, the Deciding Member Group shall have the sole right to elect whether the
Company shall pursue the Company Opportunity.  The Deciding Member Group
shall have thirty (30) days after receipt of an Opportunity Notice to notify the
Proposing Member of the Company’s desire to pursue the Company Opportunity
(the “Response”).
 

	
  
 
  	
  
                
(i)          If
the Deciding Member Group delivers a Response that the Company elects to pursue
the Company Opportunity, then the Company shall use its best efforts to (A)
enter into good faith negotiations regarding the Company Opportunity within
fifteen (15) days after the Deciding Member Group’s receipt of the
Opportunity Notice, and (B) negotiate the terms of and consummate the
transaction contemplated by the Company Opportunity within one-hundred fifty
(150) days after the Deciding Member Group’s receipt of the Opportunity
Notice, or such longer period as is practical under the circumstances.  In
such event, neither any Member nor any Affiliate thereof shall pursue the
Company Opportunity individually.
 
	
  
 
  	
  
 
  
	
  
 
  	
  
                
(ii)          If
the Deciding Member Group delivers a Response that the Company elects to forego
the Company Opportunity, the Company shall not pursue the Company Opportunity.
In such event, the Proposing Member or any Affiliate thereof shall be free to
pursue the Company Opportunity.
 

	
  
 
  	
  
          (c)
               In
the event that a Member or its Affiliates become aware of a Company Opportunity
that is part of an Ancillary Transaction, the Member or Affiliate shall follow
the procedures set forth in this Section 14.5(c) in lieu of those set forth in
Section 14.5(b). An “Ancillary Transaction” is a transaction in which
a Member or its Affiliate proposes, in the same or in a series of related
transactions, to purchase or engage in both (a) a Company Opportunity that would
be subject to Section 14.5(b), and (b) businesses or operations that, by
themselves, would not constitute a Company Opportunity subject to Section
14.5(b) (“Other Business”); provided, however, that a
transaction is not an Ancillary Transaction if the revenues for the Company
Opportunity for the preceding calendar year are more than 25% of the combined
revenues of the Company Opportunity and Other Business for such period. 
With respect to any Company Opportunity that is included in an Ancillary
Transaction, the Member or its affiliate pursuing such Company Opportunity may
consummate the Ancillary Transaction without violating this Section 14.5
provided that the acquiring Member or Affiliate within six months after the
Ancillary Transaction consummates a sale of the Company Opportunity to the
Company with the express written consent of the Member Group of which it is not
a member, which may be withheld in such other Member Group’s sole
discretion, for a purchase price equal to (A) the percentage of the EBITDA of
the Company Opportunity for the preceding calendar year compared to the combined
EBITDA of the Company Opportunity and Other Business for such period, multiplied
by (B) the total purchase price for the Ancillary Transaction; provided that, if
the other Member Group elects not to consummate the sale of the Company
Opportunity to the Company, the acquiring Member shall be free to keep and
pursue the Company Opportunity.
 

23

          Section
14.6          Confidentiality;
Non-Competition; Non-Solicitation.

	
  
 
  	
  
            
(a)              Each
Member recognizes and acknowledges that it may receive certain confidential and
proprietary information and trade secrets of the Company and its Affiliates,
including but not limited to confidential information of regarding identifiable,
specific and discrete business opportunities being pursued by the Company or its
Affiliates (the “Confidential Information”).  Each Member
(on behalf of itself and, to the extent that such Member would be responsible
for the acts of the following persons under principles of agency law, its
directors, officers, shareholders, managers, partners, employees, agents and
members) agrees that it will not, during or after the term of this Agreement,
whether through an Affiliate or otherwise, take commercial or proprietary
advantage of or profit from any Confidential Information or disclose
Confidential Information to any third party for any reason or purpose
whatsoever, except (i) to authorized representatives and employees of the
Company or its Affiliates and as otherwise may be proper in the course of
performing such Member’s obligations, or enforcing such Member’s
rights, under this Agreement; (ii) as part of such Member’s normal
reporting or review procedure, or in connection with such Member’s or its
Affiliates’ normal marketing, informational or reporting activities, or to
such Member’s (or any of its Affiliates’) auditors, attorneys or other
agents; (iii) to any bona fide prospective purchaser of the equity or
assets of such Member or its Affiliates or the Shares held by such Member, or
prospective merger partner of such Member or its affiliates, provided
that such purchaser or merger partner agrees to be bound by the
provisions of this Section 14.6; or (iv) as is required to be disclosed
by order of a court of competent jurisdiction, administrative body or
governmental body, or by subpoena, summons or legal process, or by law, rule or
regulation, provided that the Member required to make such
disclosure shall provide to the Board prompt notice of any such
disclosure.  For purposes of this Section 14.6,
“Confidential Information” shall not include any information of
which such Member (or its affiliates) learns from sources other than the
Company, whether prior to or after such information is actually disclosed by the
Company.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (b)             During
the term of and for a period of 24 months after the termination of this
Agreement, neither Levy nor USC nor any of their respective affiliates will,
engage, directly or indirectly, in the Business in the State of Michigan except
through its ownership of the Company or after compliance with Section
14.5 above.
 

24

	
  
 
  	
  
          (c)             During
the term of and for a period of 24 months after the termination of this
Agreement, (i) neither Member nor any of its Affiliates shall directly solicit
or induce any officer, director or other employee (each a “Restricted
Person”) of the Company, the other Member or any of their Affiliates to
leave the employ of the Company, the other Member or such Affiliate; and (ii)
the Company shall not directly solicit or induce any Restricted Person of either
Member or their Affiliates to leave the employ of such Member or affiliate
without the prior written consent of such Member or Affiliate.  The
foregoing covenants against solicitation of employees shall not apply to any of
a party’s employees who, without any solicitation or recruitment by the
other party, contacts the other party regarding possible employment, including
without limitation, in response to any general advertisement.
 
	
   
  	
  
 
  
	
  
 
  	
  
          (d)             Each
party acknowledges that its obligations under this Section 14.6 are of a
special, unique and extraordinary character, that they are reasonably related to
the legitimate business interests of the Members, Company and/or their
respective Affiliates, and that a failure to perform any such obligation or a
violation of such obligations under this Section 14.6 would cause
irreparable harm to the Members, Company and/or their respective Affiliates and
the Business, the amount of which may not be readily ascertainable and for which
adequate compensation could not be fashioned.  Accordingly, each party
agree that each other party will have the right, without the need to prove
irreparable injury or to post bond, to obtain an immediate injunction against
any breach or threatened breach of this Section 14.6, as well as the
right to pursue any and all other rights and remedies available at law or in
equity.
 

          Section
14.7          Member Group
Representative.

          Each Member Group
shall appoint one Member as its representative (a “Member Group
Representative”), and all actions to be taken, and notices received or
given, under this Agreement by a Member Group Representative will be binding
upon its Member Group and each Member thereof. The initial USC Member Group
Representative is Kurtz Gravel Company, and the initial Levy Member Group
Representative is Levy.

Exhibit 5.3

          The Buy-Sell Price
per share shall be a price per Share determined by the Terminating Group, but
shall in no event be less than (i) the Stipulated Price (determined below)
divided by (ii) the total number of Shares outstanding. For purposes hereof, the
“Stipulated Price” shall mean the average annual reported EBITDA
(earnings before interest, tax, depreciation and amortization, the components of
which are determined in accordance with GAAP) excluding any extraordinary gain
or loss and excluding any rebates described in Section 9.1(e), of the Company,
averaged over the three most recently completed fiscal years, multiplied by a
factor of five (5); provided, however, that 

          (i)          all
references to “Stipulated Price” assume that the Company has no
indebtedness for borrowed money (“Debt”), and has no cash; the
“Stipulated Price” shall in all cases be decreased by the principal
amount and any accrued interest relating to any Debt outstanding as of the
closing of the purchase, and shall be increased by the amount of cash and cash
equivalents of the Company as of the closing of the purchase;

          (ii)         during
2007, 2008 and 2009, the Stipulated Price (before giving effect to clause (a)(i)
above) shall equal $119,000,000.
