                                 PARENT GUARANTY


          PARENT GUARANTY dated as of September 30, 1999 made by BMAC Holdings,
Inc., a Delaware corporation (the "Guarantor"), in favor of the Secured Parties
                                   ---------
(as defined in the Credit Agreement referred to below).

          PRELIMINARY STATEMENT.  Better Minerals & Aggregates Company, a
Delaware corporation formerly known as "USS Intermediate Holdco, Inc." (the
"Borrower"), the Guarantor and George F. Pettinos (Canada) Limited, a
- ---------
corporation organized and existing under the laws of Ontario Canada (the
"Canadian Borrower"), have entered into a Credit Agreement dated as of September
- ------------------
30, 1999 (said agreement, as it may hereafter be amended or otherwise modified
from time to time, being the "Credit Agreement"; the terms defined therein and
                              ----------------
not otherwise defined herein being used herein as therein defined), with certain
Lender Parties party thereto and Banque Nationale de Paris, as Agent for such
Lender Parties and as Swing Line Bank and Initial Issuing Bank.  It is a
condition precedent to the making of Advances, the purchasing, accepting or
renewing of a Bankers' Acceptance and the issuance of Letters of Credit by the
Lender Parties under the Credit Agreement and the entry by the Hedge Banks into
Bank Hedge Agreements with the Loan Parties from time to time that the Guarantor
shall have executed and delivered this Guaranty.

          NOW, THEREFORE, in consideration of the premises and in order to
induce the Lender Parties to make Advances and Drawings and to issue Letters of
Credit under the Credit Agreement from time to time and the Hedge Banks to enter
into Bank Hedge Agreements with the Loan Parties from time to time, the
Guarantor hereby agrees as follows:

          Section 1.  Guaranty.  The Guarantor hereby unconditionally and
                      --------
irrevocably guarantees the punctual payment when due, whether at stated
maturity, by acceleration or otherwise, of all Obligations of the Loan Parties
now or hereafter existing under the Loan Documents, whether for principal,
interest, fees, expenses or otherwise (such Obligations being the "Guaranteed
                                                                   ----------
Obligations").  Without limiting the generality of the foregoing, the
- -----------
Guarantor's liability shall extend to all amounts that constitute part of the
Guaranteed Obligations and would be owed by the Borrower or the Canadian
Borrower to the Agent or any other Secured Party under the Loan Documents but
for the fact that they are unenforceable or not allowable due to the existence
of a bankruptcy, reorganization or similar proceeding involving such Borrower or
such Canadian Borrower.


          Section 2.  Guaranty Absolute.  The Guarantor guarantees that the
                      -----------------
Guaranteed Obligations will be paid strictly in accordance with the terms of the
Loan Documents, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Agent or any other Secured Party with respect thereto.  The Obligations of the
Guarantor under this Guaranty are independent of the Guaranteed Obligations or
any other Obligations of any other Loan Party under the Loan Documents, and a
separate action or actions may be brought and prosecuted against the Guarantor
to enforce this Guaranty, irrespective of whether any action is brought against
the Borrower, the Canadian Borrower or any other Loan Party or whether the
Borrower, the Canadian Borrower or any other Loan Party is joined in any such
action or actions.  The liability of the Guarantor under this Guaranty shall be
irrevocable, absolute and unconditional irrespective of, and the Guarantor
hereby irrevocably waives any defenses it may now or hereafter have in any way
relating to, any or all of the following:

          (a) any lack of validity or enforceability of any Loan Document or any
     agreement or instrument relating thereto;

          (b) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Guaranteed Obligations or any other
     Obligations of any other Loan Party under the Loan Documents, or any other
     amendment or waiver of or any consent to departure from any Loan Document,
     including, without limitation, any increase in the Guaranteed Obligations
     resulting from the extension of additional credit to the Borrower, the
     Canadian Borrower or any of their Subsidiaries or otherwise;

          (c) any taking, exchange, release or non-perfection of any Collateral,
     or any taking, release or amendment or waiver of or consent to departure
     from any other guaranty, for all or any of the Guaranteed Obligations;

          (d) any manner of application of Collateral, or proceeds thereof, to
     all or any of the Guaranteed Obligations, or any manner of sale or other
     disposition of any Collateral for all or any of the Guaranteed Obligations
     or any other Obligations of any other Loan Party under the Loan Documents
     or any other assets of the Borrower, the Canadian Borrower or any of their
     Subsidiaries;

          (e) any change, restructuring or termination of the corporate
     structure or existence of the Borrower, the Canadian Borrower or any of
     their Subsidiaries;

          (f) any failure of any Secured Party to disclose to the Borrower, the
     Canadian Borrower, the Guarantor or any other Loan Party any information
     relating to the financial condition, operations, properties or prospects of
     any other Loan Party now or in the future known to any Secured Party (the
     Guarantor waiving any duty on the part of the Secured Parties to disclose
     such information); or

          (g) any other circumstance (including, without limitation, any statute
     of limitations) or any existence of or reliance on any representation by
     the Agent or any other Secured Party that might otherwise constitute a
     defense available to, or a discharge

                                       2


     of, the Borrower, the Canadian Borrower, the Guarantor, any other Loan
     Party or any other guarantor or surety.

          This Guaranty shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Guaranteed Obligations is
rescinded or must otherwise be returned by any Secured Party or any other Person
upon the insolvency, bankruptcy or reorganization of the Borrower, the Canadian
Borrower or any other Loan Party or otherwise, all as though such payment had
not been made.

          Section 3.  Waivers and Acknowledgments.  (a)  The Guarantor hereby
                      ---------------------------
waives promptness, diligence, notice of acceptance and any other notice with
respect to any of the Guaranteed Obligations and this Guaranty and any
requirement that the Agent or any other Secured Party protect, secure, perfect
or insure any Lien or any property subject thereto or exhaust any right or take
any action against the Borrower, the Canadian Borrower or any other Person or
any Collateral.

          (b) The Guarantor hereby waives any right to revoke this Guaranty, and
acknowledges that this Guaranty is continuing in nature and applies to all
Guaranteed Obligations, whether existing now or in the future.

          (c) The Guarantor acknowledges that it will receive substantial direct
and indirect benefits from the financing arrangements contemplated by the Loan
Documents and that the waivers set forth in this Section 3 are knowingly made in
contemplation of such benefits.

          Section 4.  Subrogation.  The Guarantor will not exercise any rights
                      -----------
that it may now or hereafter acquire against the Borrower, the Canadian Borrower
or any other insider guarantor that arise from the existence, payment,
performance or enforcement of the Guarantor's Obligations under this Guaranty or
any other Loan Document, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any
right to participate in any claim or remedy of the Agent or any other Secured
Party against any Loan Party or any other insider guarantor or any Collateral,
whether or not such claim, remedy or right arises in equity or under contract,
statute or common law, including, without limitation, the right to take or
receive from any Loan Party or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim, remedy or right, unless and until
all of the Obligations constituting an Advance or Drawing and all other
Guaranteed Obligations or amounts payable under this Guaranty shall have been
paid in full in cash, all Bank Hedge Agreements shall have expired or terminated
and the Commitments shall have expired or terminated.  If any amount shall be
paid to the Guarantor in violation of the preceding sentence at any time prior
to the later of the payment in full in cash of the Guaranteed Obligations and
all other amounts payable under this Guaranty and the later of (i) the
Termination Date and (ii) the expiration or termination of all Bank Hedge
Agreements, such amount shall be held in trust for the benefit of the Agent and
the other Secured Parties and shall forthwith be paid to the Agent to be
credited and applied to the Guaranteed Obligations and all other amounts payable
under this Guaranty, whether matured or unmatured, in accordance with the terms
of the Loan Documents.  If (i) the Guarantor shall make payment to the Agent or
any other Secured Party of all or any part of the Guaranteed Obligations, (ii)
all of the

                                       3


Guaranteed Obligations payable under this Guaranty shall be paid in full in cash
and (iii) the Termination Date shall have occurred and all Bank Hedge Agreements
shall have expired or terminated, the Agent and the other Secured Parties will,
at the Guarantor's request and expense, execute and deliver to the Guarantor
appropriate documents, without recourse and without representation or warranty,
necessary to evidence the transfer by subrogation to the Guarantor of an
interest in the Guaranteed Obligations resulting from such payment by the
Guarantor.

          Section 5.  Payments Free and Clear of Taxes, Etc.  (a)  Any and all
                      -------------------------------------
payments by the Guarantor hereunder shall be made, in accordance with Section
2.14 of the Credit Agreement, free and clear of and without deduction or
withholding for any and all Taxes.  If the Guarantor shall be required by law to
deduct any Taxes from or in respect of any sum payable hereunder to any Lender
Party or the Agent, (i) the sum payable shall be increased as may be necessary
so that after making all required deductions or withholdings (including
deductions applicable to additional sums payable under this Section 5) such
Lender Party or the Agent (as the case may be) receives an amount equal to the
sum it would have received had no such deductions or withholdings been made,
(ii) the Guarantor shall make such deductions or withholdings and (iii) the
Guarantor shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law.

          (b) In addition, the Guarantor shall pay any Other Taxes.

          (c) The Guarantor shall indemnify each Lender Party and the Agent for
the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 5 paid by such Lender Party or the Agent (as the case may be) and any
liability (including penalties, additions to tax, interest and expenses) arising
therefrom or with respect thereto.  This indemnification shall be made within 30
days from the date such Lender Party or the Agent (as the case may be) makes
written demand therefor and provides the Guarantor with evidence of such
liability reasonably satisfactory to the Guarantor.

          (d) Within 30 days after the date of any payment of Taxes, the
Guarantor shall furnish to the Agent, at its address referred to in Section 8.02
of the Credit Agreement, the original receipt of payment thereof, a certified
copy of such receipt or other evidence of payment reasonably acceptable to the
Agent.  In the case of any payment hereunder by or on behalf of the Guarantor
through an account or branch outside the United States or on behalf of the
Guarantor by a payor that is not a United States person, if the Guarantor
determines that no Taxes are payable in respect thereof, the Guarantor shall
furnish, or shall cause such payor to furnish, to the Agent, at such address, an
opinion of counsel acceptable to the Agent stating that such payment is exempt
from Taxes.  For purposes of this subsection (d) and subsection (e), the terms
"United States" and "United States person" shall have the meanings specified in
- --------------       --------------------
Section 7701 of the Internal Revenue Code.

          (e) Each Lender Party organized under the laws of a jurisdiction
outside the United States shall, on or prior to the date of its execution and
delivery of the Credit Agreement in the case of each Initial Lender or the
Initial Issuing Bank, as the case may be, and on the date

                                       4


of the Assignment and Acceptance pursuant to which it became a Lender Party in
the case of each other Lender Party, and from time to time thereafter if
requested in writing by the Guarantor or the Agent (but only so long thereafter
as such Lender Party remains lawfully able to do so and in any event prior to
the date of the first payment to such Lender Party hereunder), provide the Agent
and the Guarantor with two duly completed and executed copies of Internal
Revenue Service (the "IRS") Form 1001 or 4224, as appropriate, or any successor
                      ---
form prescribed by the IRS, certifying (if it is the case) that such Lender
Party is exempt from or is entitled to a reduced rate of United States
withholding tax on payments pursuant to this Guaranty or in respect of any
Bankers' Acceptances or to the extent permitted by law, as an alternative to
such Form 1001 or 4224, each such Lender Party may provide the Guarantor and the
Agent with two duly completed and executed copies of IRS Form W-8, or any
successor form prescribed by the IRS, certifying that such Lender Party is
exempt from United States federal withholding tax pursuant to Section 871(h) or
Section 881(c) of the Internal Revenue Code, together with an annual certificate
in form and substance satisfactory to the Guarantor or the Agent stating that
such Lender Party is not a "person" described in Section 871(h)(3) or 881(c)(3)
of the Internal Revenue Code. If the forms provided by a Lender Party at the
time such Lender Party first becomes a party to the Credit Agreement indicate a
tax rate with respect to Home Jurisdiction Withholding Tax in excess of zero,
withholding tax at such rate shall be considered excluded from Taxes unless and
until such Lender Party provides the appropriate form certifying that a lesser
rate applies, whereupon such withholding tax at such lesser rate only shall be
considered excluded from Taxes for periods governed by such form; provided,
                                                                  --------
however, that, if at the date of the Assignment and Acceptance pursuant to
- -------
which a Lender Party becomes a party to this Guaranty, the Lender Party assignor
was entitled to payments under subsection (a) in respect of Home Jurisdiction
Withholding Tax with respect to interest paid at such date, then, to such
extent, the term Taxes shall include (in addition to withholding taxes that may
be imposed in the future or other amounts otherwise includable in Taxes) Home
Jurisdiction Withholding Tax, if any, applicable with respect to the Lender
Party assignee on such date. If any form or document referred to in this
subsection (e) requires the disclosure of information not substantially similar
to the information necessary to compute the tax payable and information required
on the date hereof by IRS Form 1001 or 4224, and which a Lender Party reasonably
considers to be confidential, the Lender Party shall give notice thereof to the
Guarantor and shall not be obligated to include in such form or document such
confidential information.

          (f) For any period with respect to which a Lender Party has failed to
provide the Guarantor with the appropriate form described in subsection (e) duly
completed and executed (other than if such failure is due to a change in law
occurring after the date on which a form originally was required to be provided
or if such form otherwise is not required under subsection (e) above), such
Lender Party shall not be entitled to indemnification under subsection (a) or
(c) of this Section 5 with respect to Taxes imposed by the United States by
reason of such failure; provided, however, that should a Lender Party become
                        --------  -------
subject to Taxes because of its failure to deliver a form required hereunder,
the Guarantor shall take such steps as such Lender Party shall reasonably
request at such Lender Party's sole expense to assist such Lender Party to
recover such Taxes.

                                       5


          (g) Any Lender Party claiming additional amounts payable pursuant to
this Section 5 shall use reasonable efforts (consistent with its internal policy
and legal and regulatory restrictions) to file any certificate or document
requested by the Guarantor or to change the jurisdiction of its Applicable
Lending Office if the making of such filing or change would avoid the need for
or reduce the amount of any such additional amounts which may thereafter accrue
and would not, in the sole judgment of such Lender Party, be disadvantageous to
such Lender Party.

          (h) If any Lender Party receives a refund of any Taxes or Other Taxes
paid by the Guarantor pursuant to Section 5(a), Section 5(b), or Section 5(c),
such Lender Party shall, within 30 days of such receipt, pay to the Guarantor
the amount so received, net of all out-of-pocket expenses of such Lender Party
with respect thereto, provided, however, that such Lender Party shall (i) be
                      --------  -------
required to pay to the Guarantor only such amounts as such Lender Party, in its
sole discretion, determines is attributable to Taxes or Other Taxes paid by the
Guarantor pursuant to Section 5(a), Section 5(b) or Section 5(c), and (ii) have
the sole discretion to determine whether to contest the imposition of any Taxes
or Other Taxes, regardless of whether such Taxes or Other Taxes were correctly
or legally asserted.

          Section 6.  Representations and Warranties.  The Guarantor hereby
                      -------------------------------

     reasonably expected to have a Material Adverse Effect and (iii) has all
     requisite corporate power and authority to own or lease and operate its
     properties and to carry on its business as now conducted and as proposed to
     be conducted, except to the extent that the failure to do so is not

          (b) The execution, delivery and performance by the Guarantor of this
     Guaranty are within the Guarantor's corporate powers, have been duly
     authorized by all necessary corporate action, and do not (i) contravene the

     Governors of the Federal Reserve System), order, writ, judgment,

     contract, indenture, mortgage, deed of trust, lease or other instrument
     binding on or affecting the Guarantor, any of its Subsidiaries or any of
     its or their properties, the effect of which conflict, breach or default is
     reasonably likely to have a Material Adverse Effect or (iv) except for the
     Liens created under the Loan Documents, result in or require the creation
     or imposition of any Lien upon or with respect to any of the properties of
     the Guarantor or any of its Subsidiaries.  The Guarantor is not in
     violation of any such law, rule, regulation, order, writ, judgment,
     injunction, decree,

                                       6


     determination or award, or in breach of any such contract, loan agreement,
     indenture, mortgage, deed of trust, lease or other instrument, the
     violation or breach of which is reasonably expected to have a Material
     Adverse Effect.

          (c) No authorization or approval or other action by, and no notice to

     exercise by the Agent, any Lender Party or any Hedge Bank or any Lender
     Party of its rights under this Guaranty.

          (d) This Guaranty has been duly executed and delivered by the
     Guarantor. This Guaranty is the legal, valid and binding obligation of the
     Guarantor, enforceable against the Guarantor in accordance with its terms

     Guaranty that have not been satisfied or waived.

          (f) The Guarantor has, independently and without reliance upon the

          (g) The Guarantor owns no material assets other than the Pledged

notices and other communications shall, when mailed, telegraphed, telecopied or
delivered, be effective when received by the addressee.

          Section 11.  No Waiver; Remedies.  No failure on the part of the
                       --------------------
Agent or any other Secured Party to exercise, and no delay in exercising, any
right hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right hereunder preclude any other or further exercise
thereof or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

          Section 12.  Right of Set-off.  Upon (a) the occurrence and during
                       ----------------
the continuance of any Event of Default and (b) either the making of the request
or the granting of the consent specified by Section 6.01 of the Credit Agreement
to authorize the Agent to declare the Advances and all other amounts payable
under the Credit Agreement and the other Loan Documents to be due and payable
pursuant to the provisions of said Section 6.01 or making of the demand
specified by Section 6.02 of the Credit Agreement requiring the Borrower to pay
amounts in respect of Letters of Credit or the Canadian Borrower to pay amounts
in respect of Bankers' Acceptances, each Lender Party and each of its respective
affiliates is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender Party or such Affiliate to
or for the credit or the account of the Guarantor against any and all of the
Obligations of the Guarantor now or hereafter existing under this Guaranty,
whether or not such Lender Party shall have made any demand under this Guaranty
and although such Obligations may be unmatured.  Each Lender Party agrees
promptly to notify the Guarantor after any such set-off and application;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of each Lender Party and
its respective Affiliates under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) that such
Lender Party and its respective Affiliates may have.

Commitment, the Advances owing to it and the Note or Notes held by it) to any
other Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Secured Party herein or otherwise,
in each case as and to the extent provided in Section 8.07 of the Credit

                       -------------------------
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.  Delivery of an executed counterpart of a signature page to this

(a)  This Guaranty shall be governed by, and construed in accordance with, the
laws of the State of New York.

          (b) The Guarantor hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any New York State
court or federal court of the United States of America sitting in New York City,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Guaranty or any of the other Loan Documents to which
it is or is to be a party, or for recognition or enforcement of any judgment,
and the Guarantor hereby irrevocably and unconditionally agrees that all claims
in respect of any such action or proceeding may be heard and determined in any
such New York State court or, to the extent permitted by law, in such federal
court.  The Guarantor agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.  Nothing in this
Guaranty shall affect any right that any party may otherwise have to bring any
action or proceeding relating to this Guaranty or any of the other Loan
Documents to which it is or is to be a party in the courts of any jurisdiction.

          (c) The Guarantor irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Guaranty or any of the other Loan Documents
to which it is or is to be a party in any New York State or federal court.  The
Guarantor hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

                                       9


          (d) The Guarantor hereby irrevocably waives all right to trial by jury
in any action, proceeding or counterclaim (whether based on contract, tort or
otherwise) arising out of or relating to any of the Loan Documents, the
transactions contemplated thereby or the actions of the Agent or any other
Secured Party in the negotiation, administration, performance or enforcement
thereof.

          IN WITNESS WHEREOF, the Guarantor has caused this Guaranty to be duly
executed and delivered by its officer thereunto duly authorized as of the date
first above written.
