     2.  THE LOANS

          2.1  Term Loan.  The maximum principal amount of the Term Loan, as
continued, amended and restated hereby, shall be $15,000,000.  On the date of
Closing, Bank shall continue the principal balance of the Term Loan
outstanding on the date of Closing under the Prior Loan Agreement as a portion
of the Term Loan hereunder.  Subject to Borrower's satisfaction of the
conditions precedent set forth in Section 4.1 hereof prior to any additional
advance, Bank shall fund the portion of the Term Loan not outstanding under
the Prior Loan Agreement from time to time, but not more frequently then four
times in any calendar month, in amounts not less than $100,000 or integral
multiples of $50,000 in excess of such amount, upon Borrower's submission to
Bank of a summary of costs and expenses incurred to date in connection with
Borrower's plant modernization and expansion project in Cleburne, Texas and a
completed and executed Notice of Borrowing.

               2.1.1  Term Loan Interest Rate.  The Term Loan shall bear
interest at the Interest Rate Options selected by Borrowers pursuant to a
Notice of Borrowing delivered to Bank within the applicable time period(s) for
such desired Interest Rate Option (or at the Base Rate if notice is not given
within the applicable time period(s) for other Interest Rate Options). The
Term Loan shall bear interest on the unpaid principal balance thereof, (i)
with respect to Base Rate Loans, at the Base Rate, (ii) with respect to
Adjusted LIBOR Loans at the Adjusted LIBOR plus 1.65% per annum on the
relevant Interest Rate Determination Date, and (iii) with respect to Fixed
Rate Loans, at the Fixed Rate. During the term of the Term Loan, Borrowers may
request, by submitting to Bank a Notice of Rate Election, to change or
continue the Interest Rate Option on all or a portion of the Term Loan to a




                                     13
<PAGE>
rate based on the applicable Base Rate, Adjusted LIBOR, or the Fixed Rate.

               2.1.2  Payment of Principal and Interest.  Principal with
respect to the Term Loan shall be paid in 59 equal monthly installments of
$178,571 each, commencing on the first Business Day of the month next
following the Term Loan Amortization Date, with a final balloon payment of the
remaining outstanding principal balance of the Term Loan, together with all
accrued and unpaid interest and Bank's Costs pertaining thereto, due on the
Term Loan Termination Date.  Each installment of principal hereunder,
including the final balloon payment, shall be due on the first Business Day of
each month.  Interest on the Term Loan shall be payable as set forth in
Section 2.4.5 hereof, at the Interest Rate Option selected pursuant to Section
2.4.2 hereof.

               2.1.3  Term Note.  To evidence Borrowers' joint and several
obligations under the Term Loan, Borrowers shall execute and deliver to Bank
the Term Note.

               2.1.4  Quotations of Fixed Rate.  Upon the joint written
request of the Borrowers from time to time, the Bank agrees to quote to the
Borrowers a fixed rate per annum to which the Bank would be willing to
convert the interest rate under the Term Loan for the remaining term thereof,
or a portion of such remaining term, all as specified in the Borrowers'
written request for such quotation.  If the quoted rate is acceptable to the
Borrowers (it being understood that nothing contained in this Section shall
obligate the Borrowers to borrow from the Bank, or the Bank to lend to the
Borrowers, on any terms, other than those set forth in this Agreement, which
are not mutually agreeable to all parties at the time), the Borrowers shall
so notify the Bank by submitting to Bank a properly completed and executed
Notice of Rate Election.  At any time when the Term Loan bears interest at the
Fixed Rate, Borrowers may not convert the interest rate under the Term Loan
to the Base Rate or the Adjusted LIBOR, unless Borrowers shall have paid to
Bank the conversion premium set forth in Section 2.4.8.3 hereof.

          2.2  Revolving Credit.

               2.2.1  Revolving Credit.  Provided that no Event of Default or
Unmatured Event of Default has occurred and is continuing and subject to the
terms and conditions set forth herein, commencing on the Closing Date and
expiring on the Revolving Credit Termination Date, Bank shall extend to
Borrowers the Revolving Credit, pursuant to which Bank: (i) shall extend Cash
Advances to Borrowers, in amounts not to exceed $4,000,000, and which, if not
exhausting the unadvanced portion of the Revolving Credit, shall be at least
$50,000 or integral multiples thereof requested by the Borrowers (within the
limits of the Revolving Credit), which the Borrowers may, from time to time,
repay, and, subject to the terms hereof, reborrow; and (ii) shall, within the
limits of the Revolving Credit, issue Letters of Credit in the aggregate face
amount issued at any one time not to exceed the sum of $750,000.  Borrowers
may not reborrow under the Revolving Credit after the Revolving Credit
Termination Date.

               2.2.2  Revolving Credit Interest Rate.  Cash Advances under the




                                     14
<PAGE>
Revolving Credit shall bear interest on the unpaid principal balance thereof
from the Funding Date of each Cash Advance until paid in full (whether by
acceleration or otherwise), with respect to Base Rate Loans at the Base Rate,
and with respect to Adjusted LIBOR Loans at the Adjusted LIBOR plus 1.5% per
annum on the relevant Interest Rate Determination Date. The applicable basis
for determining the Interest Rate Option with respect to each Revolving Credit
Loan shall be selected by Borrowers at the time a Notice of Borrowing or
Notice of Rate Election is given pursuant to Sections 2.4.1 and 2.4.2 hereof.

               2.2.3  Payment of Principal and Interest.  The outstanding
principal balance of, and any accrued and unpaid interest on, all Cash
Advances under the Revolving Credit, and all Bank's Costs pertaining thereto,
shall be payable on the earlier to occur of (i) the Revolving Credit
Termination Date, or (ii) the date on which the same is payable as provided in
Section 8.2 hereof.  Interest on the Revolving Credit shall be payable as
provided in Section 2.4.5 hereof.

               2.2.4  Revolving Credit Note.  To evidence Borrowers' joint and
several obligations under the Revolving Credit, Borrowers shall execute and
deliver to Bank the Revolving Credit Note.

               2.2.5  Renewal.  Upon being so requested by Borrowers in
writing at least 90 days prior to the Revolving Credit Termination Date, Bank
may, but shall not be obligated to, renew the Revolving Credit for one year by
giving written notice to Borrowers in the manner set forth in Section 9.3
hereof on or before 60 days prior to the Revolving Credit Termination Date.
In the event Bank fails to provide any notice to Borrowers regarding renewal
of the Revolving Credit, the Revolving Credit Termination Date shall not be
extended and all outstanding Cash Advances under the Revolving Credit and all
interest and Bank's Costs pertaining thereto shall become due and payable as
provided in Section 2.2.3 hereof.

               2.2.6  Letters of Credit.  Upon Bank's receipt of any
Borrower's completed and executed Application and Agreement for Irrevocable
Standby Letter of Credit, specifying the face amount, the expiration date, and
the payment terms of the intended Letter of Credit at least two (2) Business
Days before the proposed date of issuance, Bank shall issue a Letter of Credit
to a beneficiary designated by such Borrower for the purpose of
collateralizing such of that Borrower's obligations arising in the ordinary
course of business as are required to be secured by a Letter of Credit.  The
maximum aggregate face amounts of issued Letters of Credit hereunder shall not
exceed $750,000 at any one time.  No Letter of Credit hereunder shall be
issued with an expiration date exceeding one year, and no Letter of Credit
shall be issued after the Revolving Credit Termination Date.  Each Letter of
Credit shall be renewable at the option of such Borrower, provided however
that no Letter of Credit may be renewed for a term exceeding the Revolving
Credit Termination Date.

                    2.2.6.1  Reduction of Revolving Credit.  Letters of Credit
issued by Bank shall be considered a use of the Revolving Credit and shall
reduce, dollar-for-dollar, the available borrowings thereunder, and, upon the




                                     15
<PAGE>
termination or reduction of a Letter of Credit, shall increase the available
borrowings dollar-for-dollar, subject to the provisions of Section 2.2.7
hereof, with respect to the maximum available credit under the Revolving
Credit.

                    2.2.6.2  Draws Under Letter of Credit.  All draws paid
under Letters of Credit shall be deemed to be Cash Advances under the
Revolving Credit to be repaid in accordance with the provisions of Section
2.2.3 hereof, and shall bear interest from the date of such draw at the Base
Rate unless and until Borrowers have provided Bank with a properly completed
and executed Notice of Rate Election selecting an alternate rate of interest
for all or a portion of such Letter of Credit.

                    2.2.6.3  Letter of Credit Fees.  Borrowers agree to pay to
Bank a fee at an annual rate of 1.5% of the face amount of each Letter of
Credit issued by Bank, payable quarterly in arrears by the Borrower which is
the account party thereof, commencing on the last day of the Calendar Quarter
containing the date of issuance and continuing quarterly thereafter.  If any
Letter of Credit shall be subject to a variable face amount schedule, the fee
for such Letter of Credit shall be determined on a daily average basis.

               2.2.7  Maximum Revolving Credit.  If the outstanding principal
balance of all Cash Advances under the Revolving Credit, plus the face amount
of all issued and outstanding Letters of Credit (as the same may have been
reduced), exceeds $4,000,000 at any time, Borrowers shall immediately repay
such excess to Bank without demand or notice.

               2.2.8  Unused Fee.  Borrowers agree to pay to Bank a fee at an
annual rate of 35/100 of one percent (.35%) per annum of the aggregate daily
average unused portion of the Revolving Credit from the Closing Date to the
Revolving Credit Termination Date, payable in arrears on the last day of each
Calendar Quarter and on the Revolving Credit Termination Date.

          2.3  Line of Credit.

               2.3.1  Line of Credit.  Subject to the terms and conditions set
forth herein, and provided that no Event of Default or Unmatured Event of
Default has occurred and is continuing, commencing on the Closing Date and
terminating on the Line of Credit Termination Date, Bank may in its sole
discretion, from time to time on Borrowers' written request, extend to
Borrowers the Line of Credit pursuant to which Bank may make Cash Advances to
Borrowers in an aggregate amount not to exceed $25,000,000, which amounts
shall be in the sole discretion of Bank and shall be at least $250,000 or
integral multiples thereof, and which Borrowers may, from time to time,
borrow, repay and reborrow.  Upon being so requested in writing by Borrowers,
Bank may, but shall not be obligated to, extend the Line of Credit Termination
Date for additional 3 month periods by giving notice to Borrowers on or before
the final day of the month next preceding the then existing Line of Credit
Termination Date.  If no request is made by Borrowers, or if request is made
but no notice of extension is given by Bank on or before the aforementioned
date, on the Line of Credit Termination Date all Cash Advances under the Line




                                     16

and the Line of Credit shall terminate.

               2.3.2  Line of Credit Interest Rate.  The Line of Credit Loans

to Base Rate Loans at the Base Rate, and with respect to Adjusted LIBOR Loans

Determination Date. The applicable basis for determining the Interest Rate
Option with respect to each Line of Credit Loan shall be selected by Borrowers
at the time a Notice of Borrowing or Notice of Rate Election is given pursuant
to Sections 2.4.1 and 2.4.2 hereof.

               2.3.3  Payment of Principal and Interest.  The outstanding
principal balance of, and any accrued and unpaid interest on, each Cash
Advance under the Line of Credit, and all Bank's Costs pertaining thereto,
shall be payable at the date determined by Bank, after consulting with
Borrowers, in Bank's reasonable sole discretion exercised at the Funding Date

          2.4  General Provisions.

               2.4.1  Notice of Borrowing.  Subject to Sections 2.1, 2.2 and
2.3 hereof, whenever Borrowers desire to borrow under this Agreement,
including the unadvanced portion of the Term Loan to be funded at Closing,
Borrowers shall deliver by facsimile to Bank a properly completed and executed
Notice of Borrowing; with respect to Adjusted LIBOR Loans, such Notice of
Borrowing shall be delivered no later than 11:00 A.M. (Philadelphia time) at
least three London Business Days in advance of the proposed Funding Date, and
with respect to Base Rate Loans, such Notice of Borrowing shall be delivered
no later than 11:00 A.M. (Philadelphia time) at least one Business Day in
advance of the proposed Funding Date.

                      The Notice of Borrowing shall specify (i) the proposed
Funding Date (which shall be a Business Day), (ii) the amount of the proposed
Cash Advance (or loan under the Term Loan) , (iii) whether the amount to be
loaned is initially to consist of a Fixed Rate Loan (solely with respect to
the Term Loan), Base Rate Loan or Adjusted LIBOR Loan or a combination
thereof, and (iv) if such amount or any portion thereof is initially to be an
Adjusted LIBOR Loan, the initial Interest Period therefor. Cash Advances may
be continued as or converted into another Interest Rate Option in the manner
provided in Section 2.4.2 hereof upon the submission to Bank of a properly
completed and executed Notice of Rate Election.

                      A Notice of Borrowing or a Notice of Rate Election for
an Adjusted LIBOR Loan shall be irrevocable on and after the related Interest
Rate Determination Date, and Borrowers shall be bound to make, continue or
convert a Loan in accordance therewith.

               2.4.2  Notice of Rate Election; Failure to Give Notice.
Whenever Borrowers desire to change or continue the Interest Rate Option on
all or a portion of any Loan under this Agreement, Borrowers shall deliver to
Bank a Notice of Rate Election.  Borrowers shall deliver such Notice of Rate
Election: (i) with respect to Base Rate Loans and Fixed Rate Loans, at least
one Business Day in advance of the proposed change or continuation, and (ii)
with respect to Adjusted LIBOR Loans, no later than 11:00 A.M. (Philadelphia
time) at least three London Business Days in advance of the proposed change or
continuation. The Notice of Rate Election shall specify: (a) the proposed date
of change or continuation (which shall be a Business Day); (b) the type of
Loan and amount thereof affected; (c) the Interest Rate Option being selected;
and (d) with respect to Adjusted LIBOR Loans, the Interest Periods therefor;
provided that the minimum amount of any Adjusted LIBOR Loan shall be $100,000
and integral multiples of $50,000 in excess of that amount. If at the
termination of any Interest Period, Borrowers have failed to submit a Notice




                                     18
<PAGE>
of Rate Election, as aforesaid, to convert or to continue Adjusted LIBOR
Loans, then such Loans shall automatically be and become Base Rate Loans as of
the termination of the relevant Interest Period.

                      Upon the expiration of any Interest Period applicable to
Revolving Credit Loans or Line of Credit Loans bearing interest based on the
Adjusted LIBOR, such Loans shall be deemed repaid and reborrowed upon the
submission to Bank of a properly completed and executed Notice of Rate
Election pertaining thereto within the requisite time periods for a change or
continuation of an Interest Rate Option, and the succeeding Interest Period(s)
of such continued Loans shall commence on the first day of the Interest Period
of the Loans deemed to be reborrowed and continued.

                      Adjusted LIBOR Loans may only be converted into Base
Rate Loans or Fixed Rate Loans on the expiration date of an Interest Period
applicable thereto. In addition, no outstanding Loans may be continued after
the expiration of the Interest Period applicable thereto as, or be converted
into: (i) Fixed Rate Loans or Adjusted LIBOR Loans, when any Event of Default
or Unmatured Event of Default has occurred and is continuing; and (ii)
Adjusted LIBOR Loans, if the Interest Period relating to such conversion or
continuation would extend beyond the maturity date of such Loan.

                      If on any day a Loan is outstanding with respect to
which a Notice of Rate Election has not been delivered to Bank in accordance
with the terms of this Agreement specifying the basis for determining the
Interest Rate Option, then that Loan shall bear interest at the rate based on
the Base Rate for such type of Loan as determined pursuant to this Agreement.

               2.4.3  Funding.  Upon satisfaction of the conditions precedent
specified in Section 4.1 (in the case of the initial Cash Advances and the
unadvanced portion of the Term Loan) and Section 4.2 (in the case of all
subsequent Cash Advances under the Revolving Credit and the Line of Credit),
Bank shall cause such Cash Advances and loan under the Term Loan to be made
available to Borrowers on the Funding Date pertaining thereto by depositing
the amount thereof in the designated account of Borrowers with Bank.

               2.4.4  Interest Periods.  In connection with each Adjusted
LIBOR Loan, Borrowers shall elect an Interest Period to be applicable to such
Loan, which Interest Period shall be either a 30, 60, 90 or 180 day period;
provided that:

                    2.4.4.1  the first Interest Period for any Loan shall
commence on the Funding Date of such Loan;

                    2.4.4.2  if an Interest Period would otherwise expire on
a day which is not a Business Day, such Interest Period shall expire on the
next succeeding Business Day; provided however that for any Interest Period in
respect of an Adjusted LIBOR Loan which: (i) begins on the last Business Day
of a calendar month (or a day for which there is no numerically corresponding




                                     19
<PAGE>
day in the calendar month at the end of such Interest Period) shall end on the
last Business Day of the relevant calendar month, or (ii) would expire on a
day which is not a Business Day but is a day of the month after which no
further Business Day occurs in that month, such Interest Period shall expire
on the last Business Day of the month;

                    2.4.4.3  with respect to any Term Loan, Revolving Credit
Loan or Line of Credit Loan, no Interest Period shall extend beyond the Term
Loan Termination Date, Revolving Credit Termination Date or Line of Credit
Termination Date, respectively;

                    2.4.4.4  there shall be no more than nine total Interest
Periods outstanding at any time;

                    2.4.4.5  no Interest Period with respect to any Adjusted
LIBOR Loan may extend beyond a date on which Borrowers are required to make a
scheduled payment of principal which would require a payment to be made with
respect to such Adjusted LIBOR Loan.

               2.4.5  Interest Payments.  Subject to Section 2.4.8 hereof with
respect to prepayments, interest shall be payable on the Loans as follows:

                    2.4.5.1  interest on each Base Rate Loan and Fixed Rate
Loan shall be payable monthly in arrears on the first day of each month; the
first payment shall be made on the first day of the month next following the
Closing Date or the Funding Date, as the case may be, and the final payment
shall be made at maturity.

                    2.4.5.2  interest on each Adjusted LIBOR Loan shall be
payable in arrears on the last day of the Interest Period applicable to that
Loan; provided however that interest on Adjusted LIBOR Loans with Interest
Periods of 180 days shall be paid in arrears on the 90th day and on the last
day of the relevant Interest Period.

               2.4.6  Post-Maturity Interest.  Any principal payments on the
Loans not paid when due and, to the extent permitted by applicable law, any
interest payment on the Loans not paid when due, and any other amount due to
Bank under this Agreement or any other Loan Document not paid when due, in any
case whether at stated maturity, by notice of prepayment, by acceleration or
otherwise, shall thereafter bear interest payable upon demand at a rate which
is, with respect to Adjusted LIBOR Loans only, 5% per annum in excess of the
Adjusted LIBOR until the expiration of the then applicable Interest Period,
and after the expiration of the then applicable Interest Period, and in all
cases with respect to Base Rate Loans and Fixed Rate Loans, at a rate which is
2.75% per annum in excess of the Base Rate for Revolving Credit Loans and Line
of Credit Loans, and 3% per annum in excess of the Base Rate for the Term

<PAGE>
                    2.4.7.1  Bank shall give Borrowers prompt notice of the
Adjusted LIBOR determined for an Interest Period, and absent manifest error,
each determination of such rates by Bank shall be conclusive and binding for
all purposes hereof.

                    2.4.7.2  If Borrowers request that all or any portion of
the Loans bear interest at the Adjusted LIBOR, and Bank determines that, by
reason of circumstances affecting the interbank Eurodollar market generally,
deposits in U.S. Dollars (in the applicable amounts) are not being offered to
banks in the interbank Eurodollar market for the selected Interest Period,
then Bank shall forthwith give notice thereof to Borrowers, whereupon until
Bank notifies Borrowers that the circumstances giving rise to such suspension
no longer exist, (a) the obligation of Bank to permit the Loans to bear
interest at the Adjusted LIBOR shall be suspended so long as such
circumstances exist, and (b) Borrowers shall convert the interest rates on the
applicable portions of the outstanding Loans to the Base Rate on the last day
of the then current Interest Period.

                    2.4.7.3  If, after the date of this Agreement, the
adoption of or any change in Rules, or change in the interpretation or
administration thereof, by a governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof,
or compliance by Bank with any request or directive (whether or not having the
force of law) of any such authority, central bank or comparable agency shall
make it unlawful or impossible for Bank to make or maintain or fund loans at
the Adjusted LIBOR, the interest rates on the applicable portions of the
outstanding Loans shall be deemed to have been converted to the rate
determined for the type of Loan with reference to the Base Rate on either (i)
the last day of the then current Interest Period if Bank may lawfully continue
to maintain loans at the Adjusted LIBOR to such day, or (ii) immediately if
Bank may not lawfully continue to maintain loans at the Adjusted LIBOR to such
day.

                    2.4.7.4  If any governmental authority, central bank or
other comparable authority shall at any time impose, modify or deem applicable
any reserve (including, without limitation, any imposed by the Board of
Governors of the Federal Reserve System), any tax (including without
limitation, any United States interest equalization tax or similar tax however
named applicable to the acquisition or holding of debt obligations and any
interest or penalties with respect thereto), duty, charge, fee, deduction,
withholding special deposit or similar requirement against assets of, deposits
with or for the account of, or credit extended by, Bank, or shall impose on
Bank or the interbank Eurodollar market any other condition affecting loans at
the Adjusted LIBOR, and the result of any of the foregoing is to increase the
cost to Bank of making or maintaining the interest rate at the Adjusted LIBOR
or to reduce the amount of any sum received or receivable by Bank under this
Agreement, any of the Notes by an amount deemed by Bank to be material, then
within five days after demand by Bank, Borrowers shall pay to Bank such
additional amount or amounts as will compensate Bank for such increased cost
or reduction. Bank will promptly notify Borrowers of any event of which it has
knowledge occurring after the date hereof, which will entitle Bank to
compensation pursuant to this Section.  A certificate of Bank claiming




                                     21
<PAGE>
compensation under this Section and setting forth the additional amount or
amounts to be paid to Bank hereunder shall be conclusive in the absence of
manifest error.

                    2.4.7.5  The Adjusted LIBOR shall be adjusted
automatically on and as of the effective day of any change in the relevant
Reserve Percentage.

                    2.4.7.6  Promptly upon notice from Bank to Borrowers,
Borrowers will pay, prior to the date on which penalties attach thereto, all
present and future stamp, documentary and other similar taxes, levies, or
costs and charges whatsoever imposed, assessed, levied or collected on or in
respect of the Loans solely as a result of the interest rate being determined
by reference to the Adjusted LIBOR and/or the provisions of this Agreement
relating to the Adjusted LIBOR and/or the recording, registration,
notarization or other formalization of any thereof and/or payments of
principal, interest or other amounts made on or in respect of a Loan or
portion of a Loan when the interest rate is determined by reference to the
Adjusted LIBOR (all such taxes, levies, costs and charges being herein
collectively called "Eurodollar Rate Tax"). Bank shall, upon request of
Borrowers, provide evidence to Borrowers of the imposition of any such
Eurodollar Rate Tax.  Promptly after the date on which payment of any such
Eurodollar Rate Tax is due pursuant to applicable law, Borrowers will, at the
request of Bank, furnish to Bank evidence, in form and substance satisfactory
to Bank, that Borrowers have met their obligations under this Section.
Borrowers will indemnify Bank against, and reimburse Bank on demand for, any
Eurodollar Rate Tax, as determined by Bank in its good faith discretion. Bank
shall provide Borrowers with appropriate receipts for any payments or
reimbursements made by Borrowers pursuant to this Section. A certificate of
Bank as to any amount payable pursuant to this Section shall, absent manifest
error, be final, conclusive and binding on all parties hereto.

                    2.4.7.7  If Bank shall determine that (i) any current
Rule, law, regulation, or guideline, the adoption or imposition of any Rules,
law, regulation, or guideline any change in any Rules, law, regulation or
guideline, or the adoption, imposition or change in the interpretation or
administration thereof by a governmental authority, central bank or comparable
agency charged with the interpretation and administration thereof, or (ii)
compliance by Bank (or any lending office or any holding company of Bank) with
any request, guideline or directive whether or not having the force of law
regarding special deposit, capital adequacy, risk based capital, capital or
reserve maintenance, capital ratio, or similar requirements against loans or
loan commitments or any commitments to extend credit or other assets of or any
deposits or other liabilities taken or entered into by Bank (including the
capital adequacy guidelines promulgated by the Board of Governors of the
Federal Reserve System) and the result of any event referred to in clauses
(i) or (ii) above (x) shall be to increase the cost to Bank of making or
maintaining, or to impose upon Bank or increase any capital requirement
applicable as a result of the making or maintenance of, the Loans or the
obligations of Borrowers hereunder or (y) has or would have the effect of
reducing the rate of return or amounts receivable hereunder on any Loan as a
consequence of its obligations pursuant to this Agreement or Loans made by
Bank pursuant hereto to a level below that which Bank (or Bank's holding




                                     22
<PAGE>
company) could have achieved but for such adoption, imposition, change or
compliance (taking into consideration such Bank's policies and the policies of
Bank's holding company with respect to capital adequacy) by an amount deemed
by such holder to be material (which adoption, imposition, change, or increase
in capital requirements or reduction in amounts receivable may be determined
by Bank's good faith allocation of the aggregate of such cost increase,
capital increase or imposition or reductions in amounts receivable resulting
from such events), then, from time to time, Borrowers shall pay to Bank, on
demand by Bank as set forth below, such additional amount or amounts as will
be necessary to restore the rate of return to Bank from the date of such
change, together with interest on such amount from the date demanded until
payment thereof in full at the rate provided in this Agreement. Bank (or
Bank's holding company) shall be entitled to compensation pursuant to this
Section. A certificate of Bank claiming compensation under this Section and
setting forth the increased cost, reduction in amounts receivable additional
amount or amounts necessary to compensate Bank (or Bank's holding company)
hereunder shall be delivered to Borrowers and shall be conclusive in the
absence of manifest error. Borrowers shall pay Bank the amount shown as due on
any such certificate delivered by Bank within 10 days after Borrowers' receipt
of same. If Bank demands compensation under this Section, Borrowers may, upon
30 Business Days' prior notice to Bank, prepay in full, in accordance with
Section 2.4.8 hereof, the then outstanding: (i) Base Rate Loans and/or the
Fixed Rate Loan, together with accrued interest thereon to the date of
prepayment, and with respect to Fixed Rate Loans, together with the respective
prepayment premium as provided in Section 2.4.8.3; and/or (ii) Adjusted LIBOR
Loans together with accrued interest thereon to the date of prepayment along
with the respective prepayment penalty as provided in Section 2.4.8.2 hereof.
Concurrently with prepaying such Base Rate Loans, Fixed Rate Loan and Adjusted
LIBOR Loans, Borrowers may borrow from Bank Cash Advances at an Interest Rate
Option not so affected.

                    2.4.7.8  Failure on the part of Bank to demand
compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital with respect to any period shall
not constitute a waiver of Bank's right to demand such compensation with
respect to such period or any other period; provided however that Bank shall
demand such compensation not later than six months after Bank has received
notice of such increased costs or reduction in amounts received or receivable
or reduction in return on capital. The protection of this Section shall be
available to Bank regardless of any possible contention of the invalidity or
inapplicability of the law, rule, regulation, guideline or other change or
condition which shall have occurred or been imposed.

                    2.4.7.9  The Base Rate shall be determined and adjusted
daily.

               2.4.8  Prepayment.

                    2.4.8.1  Voluntary Prepayments.  Any Base Rate Loan or
Fixed Rate Loan may be prepaid at any time upon one Business Day's written
notice to Bank, in whole or in integral multiples of $50,000.  Borrowers'




                                     23
<PAGE>
prepayment of a Base Rate Loan shall be without premium or penalty.
Borrowers' prepayment of a Fixed Rate Loan shall be subject to the prepayment
premium set forth in Section 2.4.8.3 hereof.  Any Adjusted LIBOR Loan may be
prepaid prior to the expiration date of the Interest Period applicable thereto
subject to the provisions of Section 2.4.8.2 hereof, in integral multiples of
$50,000, and then only upon 2 days prior notice to Bank.  In the event that
Borrowers do not specify the Loan to which a prepayment is to be applied, such
prepayment shall be applied (first to interest then to principal) first to the
Revolving Credit Loans, second to the Term Loan, and third to the Line of
Credit Loans.

                    2.4.8.2  Prepayment Premium For Adjusted LIBOR Loans.
Adjusted LIBOR Loans may be prepaid as set forth in Section 2.4.8.1 hereof
only upon payment to Bank of a prepayment premium determined as follows: (i)
on the prepayment date, the remaining payments of principal and interest that
would otherwise have become payable at the expiration of the Interest Period
pertaining to the principal being prepaid shall be discounted to a present
value at a rate per annum equal to the "Prepayment Yield to Maturity", as
hereinafter defined, plus any costs for reserves or assessments or for
reinvesting the amount being prepaid, and if such discounted value shall
exceed the unpaid principal amount being prepaid, then the prepayment premium
shall be an amount equal to such excess; otherwise no prepayment premium shall
be payable; and (ii) for purposes of this Section 2.4.8.2, the "Prepayment
Yield to Maturity" shall mean the yield to maturity of the debt obligation of
the United States Treasury (excluding those commonly known as "Flower Bonds")
maturing nearest in time to the expiration of the relevant Interest Period.
The maturity date and yield to maturity of such United States Treasury
obligation shall be determined on the basis of quotations published in the
Wall Street Journal on the prepayment date. If there shall be more than one
such debt obligation of the United States Treasury maturing nearest in time
to the expiration of the relevant Interest Period, the Prepayment Yield to
Maturity shall be the arithmetic average of the yields to maturity of all such
obligations. Notwithstanding the foregoing, no amount so prepaid may be
reborrowed prior to the last day of the Interest Period pertaining to the Loan
prepaid.

                    2.4.8.3  Prepayment and Conversion Premium for Fixed Rate
Loans.  Fixed Rate Loans may be prepaid as set forth in Section 2.4.8.1
hereof, and may be converted to a Base Rate Loan or an Adjusted LIBOR Loan as
set forth in Sections 2.1.4 and 2.4.2 hereof, only upon payment to Bank of a
prepayment or conversion premium, determined on the prepayment or conversion
date, as follows: (i) the remaining payments of principal and interest that
would otherwise have been payable over the remainder of the period for which
Borrowers have elected for the Term Loan to bear interest at the Fixed Rate,
pertaining to the principal being prepaid, shall be discounted to a present
value at a rate per annum equal to the "Prepayment Yield to Maturity," plus
any costs for reserves or assessments or for reinvesting the amount being
prepaid, and if such discounted value shall exceed the unpaid principal amount
being prepaid, then the prepayment or conversion premium shall be an amount
equal to such excess; otherwise no prepayment or conversion premium shall be
payable; and (ii) for purposes of this Section 2.4.8.3, the "Prepayment Yield




                                     24
<PAGE>
to Maturity" shall mean the yield to maturity of the debt obligation of the
United States Treasury (excluding those commonly known as "Flower Bonds")
maturing nearest in time to the expiration of the period for which Borrowers
have elected for the Term Loan to bear interest at the Fixed Rate.  The
maturity date and yield to maturity of such United States Treasury obligation
shall be determined on the basis of quotations published in the Wall Street
Journal on the conversion date. If there shall be more than one such debt
obligation of the United States Treasury maturing nearest in time to the
expiration of the period for which Borrowers have elected for the Term Loan to
bear interest at the Fixed Rate, the Prepayment Yield to Maturity shall be the
arithmetic average of the yields to maturity of all such obligations.

               2.4.9  Funding Losses.  If the Borrowers fail to borrow any
Adjusted LIBOR Loans after a Notice of Borrowing or Notice of Rate Election
has been given to Bank as provided in this Article 2, Borrowers shall
reimburse Bank on demand for any resulting loss or expense incurred by it (or
by any existing or prospective participant in the related Loan), including
(without limitation) any loss incurred in obtaining, liquidating or employing
deposits from third parties, provided that Bank shall use commercially
reasonable efforts to mitigate any such loss and Bank shall have delivered to
the Borrowers a certificate as to the amount of such loss or expense, which
certificate shall be conclusive in the absence of manifest error.

               2.4.10  Manner and Time of Payment.  All payments of principal,
interest and fees hereunder and under the Notes shall be made by Borrowers
without notice, set off or counterclaim and in immediately available same day
funds and delivered to Bank not later than 12:00 noon (Philadelphia time) on
the date due at the address set forth in Section 9.3 hereof, for the account
of Bank; funds received by Bank after that time shall be deemed to have been
paid by Borrowers on the next succeeding Business Day.

               2.4.11  Use of Proceeds.  The proceeds of the Term Loan shall
be used by Borrowers for construction, equipping and operating of their
respective plants. The proceeds of the Revolving Credit Loan shall be used by
Borrowers for working capital and other corporate purposes.  The proceeds of
the Line of Credit Loan shall be used by Borrowers as temporary, initial
financing for acquisitions of entities and/or assets, and other Capital
Expenditures, in the construction materials, limestone products or related
industries.

               2.4.12  Conditional Payment.  Borrowers agree that checks and
other instruments received by Bank in payment or on account of the
Indebtedness constitute only conditional payment until such items are actually
paid to Bank.  Subject to Section 2.4.8.1 hereof, Borrowers waive any right
they may have to direct the application of any and all payments at any time or
times hereafter received by Bank on account of the Indebtedness. Borrowers
agree that Bank shall have the continuing exclusive right to apply and reapply
such payments in any manner as Bank may deem advisable, notwithstanding any
entry by Bank upon its books.

               2.4.13  Maximum Available Credit for All Loans.
Notwithstanding anything herein to the contrary, the sum of (i) the




                                     25
<PAGE>
outstanding principal balance of the Term Loan, and (ii) the outstanding
principal balance of all outstanding Cash Advances, including the aggregate
face amount of all issued Letters of Credit, shall not exceed $44,000,000.
The maximum available credit under this Agreement shall not exceed the sum of
(a) $44,000,000, plus (b) all interest, Bank's Costs and any other amount due
from Borrowers to Bank hereunder or pursuant to any other Loan Document.

               2.4.14  Mandatory Payments.  In the event that the principal
amount outstanding under (i) the Revolving Credit shall at any time exceed
$4,000,000, (ii) the Term Loan shall at any time exceed $15,000,000, or (iii)
the Line of Credit shall at any time exceed $25,000,000, then in any such
case, Borrowers shall immediately pay such excess to Bank.

               2.4.15  SWAP Agreements.  Borrowers and Bank may, but shall not
be obligated to, enter into one or more interest rate protection agreements on
terms mutually agreeable to all parties at the time, to permit  Borrowers to
hedge their interest rate liabilities hereunder.

in full.

               3.1.2  Financing Statements and Other Documents.  Each Borrower
agrees to execute and deliver to Bank any and all Financing Statements and

Permitted Liens), and may pay for the repair of any damage to the Collateral,
the maintenance and preservation thereof and for insurance thereon required by

Section 5.1.4 shall apply to the most recent Financial Statements delivered
pursuant to Section 6.1.1 hereof, and (b) any other representation and
warranty contained in Article 5 which relate to facts which have changed to an
extent permitted by this Agreement or to an extent consented to by the Bank

with all of the terms and conditions hereof, of the Notes, and of all other
Loan Documents, in each case on and as of the Funding Date; and (iii) Bank

     5.  REPRESENTATIONS AND WARRANTIES.

          5.1  Each Borrower, for itself and for all Borrowers where so
indicated, represents and warrants to Bank as follows:

               5.1.1  Good Standing; Ownership of Subsidiaries.  Each Borrower
is a corporation duly organized, validly existing and in good standing under
the laws of the state of its incorporation; has the corporate power and
authority to own and operate its respective assets and Real Estate and to
carry on such Borrower's business where and as contemplated; is duly qualified
as a foreign corporation to do business in, and is in good standing in, every
jurisdiction where the nature of such Borrower's business requires such
qualification. Each Borrower's chief executive office is located at 12221
Merit Drive, Suite 500, Dallas, Texas.  U.S. Lime owns all of the issued and
outstanding capital stock of the Subsidiaries, and except for the
Subsidiaries, U.S. Lime does not have any subsidiaries and does not conduct
business under any other trade name, or in joint venture or partnership with
any Person.  None of the Subsidiaries has any subsidiary.

               5.1.2  Power and Authority.  The making, execution, issuance
and performance by the Borrowers of this Agreement, the Notes, and the other
Loan Documents, have been duly authorized respectively by all necessary
corporate action of each Borrower and will not violate any provision of law or
regulation or of the respective charters or by-laws of the Borrowers; will not




                                     30
<PAGE>
violate any agreement, trust or other indenture or instrument to which
Borrowers or any of them is a party or by which Borrowers or any of them or
any of its or their property is bound, so that this Agreement, the Notes, and
all of the other Loan Documents when executed and delivered will be valid and
binding obligations of the Borrowers and each of them, enforceable in
accordance with their respective terms.

               5.1.3  Priority of Liens; Location and Condition of Collateral.
With the exception of Permitted Liens and except as provided in Schedule 5.1.3
hereto, (i) each Borrower owns its respective Collateral free and clear of all
liens, encumbrances, security interests or other rights of third parties,
excepting only the rights and interests granted Bank herein and in the Loan
Documents, and (ii) upon perfection of Bank's security interest in the
Collateral, Bank will have a first priority security interest in the
Collateral owned by Borrowers.  Except for moveable equipment such as
trailers, equipment in repair off-premises or otherwise in transit, warehoused
equipment, all in the ordinary course of business, all tangible assets of
Borrowers constituting Collateral will be located on each Borrower's
respective Real Estate.  None of the personal property or fixtures located on
any parcel of the Real Estate is owned by any Person other than the Borrower
which is the record titleholder to such parcel of Real Estate, except for
interests in such personal property and fixtures which constitute Permitted
Liens and except for matters disclosed in Schedule 5.1.3 hereto.

               5.1.4  Financial Condition.  The consolidated balance sheets of
U.S. Lime and its subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1996,
together with the notes thereto and the accompanying opinion of Ernst & Young,
LLP, independent certified public accountants, all heretofore furnished to the
Bank, present fairly, in all material respects, the consolidated financial
position of U.S. Lime and its subsidiaries at December 31, 1996 and 1995, and
the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1996, in conformity with GAAP.  The
condensed consolidated balance sheets of U.S. Lime and its subsidiaries as of
September 30, 1997 (unaudited) and December 31, 1996 and the related condensed
consolidated statements of operations and of cash flows of U.S. Lime and its
subsidiaries for the nine months ended September 30, 1997 and September 30,
1996 (unaudited), all heretofore furnished to the Bank, have been prepared in
all material respects in accordance with all applicable requirements of Form
10-Q of the Securities and Exchange Commission under the Securities Exchange
Act of 1934 and, in the opinion of the Borrowers' managements, reflect all
adjustments of a normal and recurring nature necessary to present fairly the
financial position, results of operations and cash flows of U.S. Lime and its
subsidiaries on a consolidated basis for the periods presented in accordance
with GAAP, except that certain information and footnote disclosures normally
included in financial statements prepared in accordance with GAAP have been
condensed or omitted.  Except as set forth on such Financial Statements and on
Schedule 5.1.4 hereto, the Borrowers do not have any material fixed, accrued
or contingent obligation or liability for taxes or otherwise that is not
disclosed or reserved against on its balance sheets.  The Borrowers have




                                     31
<PAGE>
filed all tax returns required to be filed by them with any taxing authority
and have paid all taxes with respect thereto.  Since December 31, 1996,
there have been no changes in the condition of the Borrowers' financial
position or otherwise, from that set forth in the Consolidated Balance Sheets
as of said date that would have a Materially Adverse Effect upon the
Borrowers, other than changes, if any, previously disclosed to Bank in
writing.  The Borrowers do not believe, and have no reason to believe, that
there has been or will be a change relating to the business of the Borrowers
that would cause a Materially Adverse Effect on the Borrowers or any of them.

               5.1.5  No Litigation.  Except (i) those matters referred to in
the notes to Borrowers' consolidated Financial Statements, (ii) those matters
on Schedule 5.1.5 hereto, and (iii) worker's compensation claims covered by
insurance, there are no suits or proceedings pending, or, to the knowledge of
Borrowers, or any of them, threatened against or affecting the Borrowers, or
any of them, and neither any Borrower nor the Borrowers are in default in the
performance of any agreement to which any Borrower or Borrowers may be a party
or by which any Borrower or Borrowers are bound, or with respect to any order,
writ, injunction, or any decree of any court, or any federal, state, municipal
or other government agency or instrumentality, domestic or foreign, which
suits, proceedings and defaults in the aggregate could have a Materially
Adverse Effect on any Borrower or Borrowers.

               5.1.6  Compliance.  To the best of its knowledge, each Borrower
has all Governmental Approvals necessary for the conduct of such Borrower's
business, except for Governmental Approvals the failure to obtain which could
not have a Materially Adverse Effect on such Borrower, and the conduct of each
Borrower's business is not and has not been in violation of any such
Governmental Approvals or any applicable federal or state law, rule or
regulation, which violation could have a Materially Adverse Effect on such
Borrower or Borrowers.  No Borrower requires any Governmental Approvals to
enter into, or perform under, this Agreement, the Notes, or any other Loan
Document.

               5.1.7  Compliance with Regulations U and X.  No Borrower is
engaged principally, or as one of such Borrower's important activities, in the
business of extending credit for the purpose of purchasing or carrying margin
stock (within the meanings of Regulations U and X of the Board of Governors of
the Federal Reserve System).

               5.1.8  ERISA.  With respect to each employee pension benefit
plan (within the meaning of Section 3(2) of ERISA other than any
"multiemployer plan" within the meaning of Section 3(37) of ERISA)
(hereinafter, a "Plan"), maintained for employees of any Borrower or of any
trade or business (whether or not incorporated) which is under common control
with such Borrower (within the meaning of Section 4001(b)(1) of ERISA), and
except as disclosed in Schedule 5.1.8 or as heretofore disclosed to the Bank
in writing (i) there is no accumulated funding deficiency (within the meaning
of Section 302 of ERISA or Section 412 of the Code), as of the last day of the




                                     32
<PAGE>
most recent plan year of such Plan heretofore ended, taking into account
contributions made or to be made within the time prescribed by Section 412(c)
(10) of the Code; (ii) to the best of the Borrower's knowledge, each such Plan
has been maintained in accordance with its terms and ERISA; and (iii) there
has been no "reportable event" within the meaning of Section 4043 of ERISA and
the regulations thereunder for which the 30-day notice requirement has not
been waived.  No Borrower has incurred any liability to the PBGC other than
required insurance premiums, all of which that have become due as of the date
hereof have been paid.  Schedule 5.1.8 hereto sets forth all multiemployer
plans to which Borrowers or any Borrower is a party and the most recent
information received by Borrowers or such Borrower from any multiemployer
plan (within the meaning of Section 3(37) of ERISA), regarding the estimated
amount of potential liability for a complete withdrawal from any such
multiemployer plan based on the assumptions used by any such multiemployer
plan for purposes of providing the estimate.

               5.1.9  Solvency.

                    5.1.9.1  The aggregate present fair saleable value of the
assets of Borrowers (sold as a whole) after giving effect to the funding of
all Loans hereunder exceeds the amount that will be required to be paid on or
in respect of the Debts and other liabilities (including contingent
liabilities) of Borrowers as they mature.

                    5.1.9.2  The assets of Borrowers do not in the aggregate
constitute unreasonably small capital for Borrowers to conduct their business
as now conducted and as proposed to be conducted, including the capital needs
of Borrowers.

                    5.1.9.3  Borrowers do not intend to, nor do Borrowers
believe that they will, incur Debts beyond their ability to pay as such Debts
mature (taking into account the timing and amounts of cash to be received by
Borrowers and of amounts to be payable on or in respect of Debt of Borrowers).
The cash available to Borrowers, after taking into account all other
anticipated sources and uses of the cash of Borrowers, is anticipated to be
sufficient to pay all amounts on or in respect of the Indebtedness when the
Indebtedness or any part thereof is required to be paid.

                    5.1.9.4  The aggregate fair value of Borrowers' assets
exceeds the aggregate of all their liabilities.

               5.1.10  RICO.  Neither Borrowers nor any Borrower have engaged
in any conduct or taken or omitted any actions which will, or could, if the
facts and circumstances relative thereto were discovered, give rise to a
criminal indictment or civil action against Borrowers or any Borrower under
RICO.

               5.1.11  Labor Matters.  Except to the extent set forth on
Schedule 5.1.11 hereto, (i) no Borrower is a party to any collective
bargaining agreement; (ii) no Borrower has experienced any strike, labor




                                     33
<PAGE>
dispute, slowdown or work stoppage due to labor disagreements which could have
a Materially Adverse Effect on such Borrower or Borrowers or on the value of
the Collateral or on the enforceability of the Indebtedness (including
realizing on the Collateral); (iii) to the best knowledge of each Borrower,
after due inquiry, there is no such strike, dispute, slowdown or work stoppage
threatened against any Borrower which would have a Materially Adverse Effect
on such Borrower, and (iv) no labor petitions have been filed or union
organizing activity conducted during the past six months pertaining to any
Borrower.

               5.1.12  Business.  Borrowers enjoy peaceful and undisturbed
possession under all leases of real or personal property of which any Borrower
is lessee, to the extent material to the business of such Borrower.  Borrowers
or the applicable Borrower own or possess the right to use all the franchises,
rights, licenses, goodwill and trademarks necessary for the conduct of their
business as now conducted or as contemplated to be conducted.  Borrowers own,
lease or have the right to use, all assets, franchises, rights, licenses,
goodwill and trademarks, and employ all employees and/or engage such
independent contractors, as are necessary to operate the business conducted by
each Borrower; and all of such tangible assets are in good working order,
normal wear and tear excepted.

               5.1.13  Vehicle Title and Registration.  All of each Borrower's
motor vehicles which under applicable law are  required to be registered, are
properly registered (or such registration has been properly applied for) in
the name of such Borrower, and such motor vehicles and related equipment are
fit for use and available for use without repair (except for maintenance and
repair in the ordinary course of business and except for deterioration or
obsolescence of such motor vehicles and other equipment not, taken as a whole,
material to the conduct of Borrower's Business), and the ownership of such
motor vehicles which, under applicable law, is evidenced by a Certificate of
Title is properly titled in the name of the applicable Borrower.

               5.1.14  Environmental.  

                    5.1.14.1  Except as set forth in Schedule 5.1.14 or where
failure to comply would not have or result in a Materially Adverse Effect on
any Borrower or Borrowers, or the conduct of Borrowers' or any Borrower's
Business, each Borrower has, to such Borrower's knowledge, in the conduct of
its business, and the ownership and use of its properties, complied with all
federal, state and local laws, rules, regulations, judicial decisions and
decrees pertaining to the use, storage or disposal of hazardous waste or toxic
materials.

                    5.1.14.2  To each Borrower's knowledge, except as set
forth in Schedule 5.1.14 or where the presence of a hazardous substance,
pollutant, contaminant, waste or residue waste or solid waste would not have
or result in a Materially Adverse Effect on such Borrower or on the conduct of
such Borrower's business: (i) no hazardous substance, pollutant or contaminant




                                     34

     6.  AFFIRMATIVE COVENANTS

          6.1  Borrowers' Covenants.  As long as any portion of the
Indebtedness remains outstanding and unpaid or Bank has any credit facility
available to Borrowers or any Borrower, Borrowers covenant and agree that, in
the absence of prior written consent of Bank, Borrowers will:

               6.1.1  Financial Statements.  Furnish to Bank, not later than
one hundred twenty-five (125) days after the close of each Fiscal Year, U.S.
Lime's Annual Report containing a consolidated balance sheet, of U.S. Lime and
its subsidiaries as of the last day of such Fiscal Year and related
consolidated statements of operations, stockholders' equity and cash flow for
such Fiscal Year, audited by Ernst & Young, LLP or other independent certified
public accountants of recognized standing in the financial community.  In
addition, Borrowers will furnish to Bank, within fifty (50) days of the close
of each Calendar Quarter other than the last quarter of each Fiscal Year, a
condensed consolidated balance sheet of U.S. Lime and its subsidiaries as of
the last day of such Calendar Quarter and related condensed consolidated
statements of operations and of cash flow of U.S. Lime and its subsidiaries
for such Calendar Quarter.  Each set of Financial Statements delivered to Bank
pursuant to this Section 6.1.1 shall be certified by an Authorized Officer of
U.S. Lime as having been prepared in all material respects in accordance with
all applicable requirements of Form 10-Q of the Securities and Exchange
Commission under the Securities Exchange Act of 1934 and as reflecting, in the
opinion of the Borrowers' managements, all adjustments of a normal and
recurring nature necessary to present fairly the financial position, results
of operations and cash flows of U.S. Lime and its subsidiaries on a
consolidated basis for the periods presented in accordance with GAAP.  Each
Borrower shall furnish Bank together with all Financial Statements a
certificate, substantially in the form of Schedule 6.1.1 hereto, executed by
an Authorized Officer, which certificate shall state that the signer: (i) has
reviewed the terms of this Agreement and has made, or caused to be made under
his supervision, a review in reasonable detail of the transactions and
condition of Borrowers during the accounting period covered by such Financial
Statements and that such review has not disclosed the existence during or at
the end of such accounting period, and (ii) does not have knowledge of the




                                     37
<PAGE>
existence as at the date of the certificate, of any condition or event which
constitutes an Event of Default or Unmatured Event of Default, or if any such
condition or event existed or exists, specifying the nature and period of
existence thereof and what action such Borrower has taken, is taking and
proposes to take with respect thereto, it being agreed that so long as the
Borrowers have a common Authorized Officer the substance of such certificate
may be combined into a single certificate. Borrowers shall deliver to Bank,
within 30 days of Bank's request, copies of any internal supporting schedules
and other information regarding the consolidation of Borrower's Financial
Statements;

               6.1.2  Other Financial Information.  With reasonable promptness
furnish to Bank all financial and business information provided to
stockholders of U.S. Lime, the Securities and Exchange Commission, the NASDAQ,
and such additional information and data concerning the business and financial
condition of Borrowers as may be reasonably requested by Bank.  Each Borrower
shall afford Bank or its agents access to the financial books, records,
computer tapes and properties of such Borrower at all reasonable times and
permit Bank or its agents to make copies and abstracts of same and to remove
such copies and abstracts from such Borrower's premises.  Bank shall with
respect to any and all financial statements or other reports, documents, data
and materials delivered by a Borrower to Bank pursuant to this Agreement, to
the extent that the information contained therein has not otherwise been
disclosed in such a manner as to render the same no longer confidential,
maintain the confidential nature of the information contained therein;
provided, however, that Bank may disclose such information to: (a) its
employees, agents, attorneys and accountants who would ordinarily have access
to the same in the normal course of the performance of their duties; (b)
prospective participating lenders who shall maintain the confidential nature
of such information; and (c) such third parties as may be necessary in
connection with or in response to (i) compliance with any Rule, subpoena or
investigation or (ii) any order, decree, judgment, subpoena, notice of
discovery or similar ruling or pleading issued, filed or served (x) by or
under authority of any court, tribunal, arbitration panel or any governmental
agency, commission, authority, board or similar entity or (y) in connection
with any proceeding, case or other matter pending before any court, tribunal,
arbitration panel or any governmental agency, commission, authority, board or
similar entity; provided, however, that in connection with the submission of
any information to any commiss ion, authority, board or similar entity, the
Bank shall request that the information submitted be kept confidential;

               6.1.3  Deposits at Bank.  U.S. Lime shall maintain its
principal operating accounts (excepting locally maintained payroll, petty cash
and local collection accounts) with Bank;

               6.1.4  Taxes and Claims.  Promptly pay and discharge all taxes,
governmental charges and assessments levied and assessed or imposed upon any
Borrower's assets or any portion thereof, or upon the purchase, ownership,
delivery, leasing, possession, use, operation, return or other disposition
thereof, or upon the rentals, receipts or earnings therefrom, or upon or with
respect to this Agreement, the Notes, or any other Loan Document, and pay all




                                     38
<PAGE>
other claims which, if unpaid, might become liens or charges, other than
Permitted Liens, upon the assets of any Borrower, provided, however, that
nothing in this Section 6.1.4 shall require Borrowers or any Borrower to pay
any such taxes or assessments prior to the date on which they otherwise would
become delinquent or as long as Borrowers or such Borrower shall in good
faith contest the amount or validity thereof and shall establish reserves
against such taxes and assessments in kind and amount satisfactory to Bank
and, in the case of Federal tax liens, cause same to be extinguished or
bonded;

               6.1.5  Existence.  Except in each case to the extent that the
failure to do so would not have a Materially Adverse Effect on the Borrowers
as a whole, (i) maintain the corporate existence of each Borrower and all
necessary foreign qualifications in good standing, (ii) continue to comply
with all applicable statutes, Rules and regulations with respect to the
conduct of such Borrower's business and (iii) maintain all Permits, provided
that the foregoing shall not be deemed to prohibit the merger or consolidation
of any Borrower or subsidiary of a Borrower into or with a Borrower or another
subsidiary of a Borrower;

               6.1.6  Insurance.  Maintain personal liability, casualty,
workers' compensation, property damage, flood and business interruption
insurance with respect to each Borrower's business and assets, in such
amounts, against such hazards and liabilities, and with such companies as may
be reasonably satisfactory to Bank, all such policies covering the Collateral
to insure Bank as its interests may appear.  Each Borrower shall, unless Bank
shall otherwise agree in writing to the contrary, maintain insurance as
follows:
                    (i)  Insurance against loss or damage to the Real Estate
and to all of each Borrower's inventory, equipment, furniture, fixtures and
machinery wherever located, by fire and any of the risks covered by insurance
of the type now known as "all risk" coverage in an amount not less than that
percentage of the full replacement cost of all buildings and improvements now
or hereafter erected thereon (exclusive of the cost of excavations,
foundations, and footings below the lowest basement floor), required to
satisfy any applicable coinsurance requirement in such policy and with not
more than $100,000 deductible from the loss payable for any casualty.  The
policies of insurance carried in accordance with this subparagraph (i) shall
contain the "Replacement Cost Endorsement";

                   (ii)  Business interruption insurance for the period of
time needed for restoration with 90 days coverage for ordinary payroll in such
amounts as are satisfactory to Bank;

                  (iii)  Comprehensive public liability insurance (including
coverage for elevators and escalators, if any, on any Real Estate and, if any
construction of new improvements  thereon occurs after execution of this
Agreement, completed operations coverage for one year after construction of
the improvements has been completed) on an "occurrence basis" against claims
for "personal injury", including without limitation bodily injury, death or
property damage occurring on, in or about such Real Estate and the adjoining
streets, sidewalks and passageways, such insurance to afford immediate minimum




                                     39
<PAGE>
protection to a limit of not less than that required by Bank with respect to
personal injury or death to any one or more persons or damage to property;

                   (iv)  Worker's compensation insurance (including employer's
liability insurance) for all employees of each Borrower in such amount as is
reasonably satisfactory to Bank, or, if minimum amounts are established by
law, in such amounts;

                    (v)  During the course of any construction or repair of
improvements on any Real Estate, builder's completed value risk insurance
against "all risks of physical loss", including collapse and transit coverage,
during such construction or repair, with deductibles not to exceed $100,000,
in non-reporting form, covering the total value of work performed and
equipment, supplies and materials furnished.  If requested by Bank, such
policy of insurance shall contain the "permission to occupy upon completion of
work or occupancy" endorsement;

                   (vi)  Boiler and machinery insurance covering pressure
vessels, air tanks, boilers, machinery, pressure piping, heating, air
conditioning and elevator equipment and escalator equipment, with respect to
such portions of the Real Estate as contain equipment of such nature, and
insurance against loss of occupancy or use arising from any breakdown of such
equipment, in such amounts as are reasonably satisfactory to Bank.

                    6.1.6.1  Each policy of insurance required by the terms of
this Section shall contain an endorsement or agreement by the insurer that any
loss shall be payable in accordance with the terms of such policy
notwithstanding any act or negligence of such Borrower which might otherwise
result in forfeiture of such insurance, and also an agreement by the insurer
waiving all rights of setoff, counterclaims or deductions against such
Borrower.

                    6.1.6.2  Each policy of insurance required by the terms of
this Section shall be issued by a company reasonably satisfactory to Bank,
shall be in an amount reasonably satisfactory to Bank, and if insuring against
damage to any of the Real Estate, shall have attached to it, in forms
satisfactory to Bank, both a mortgagee clause in favor of Bank, not subject to
contribution, and a lender's loss payable endorsement for the benefit of Bank.
Each Borrower shall furnish Bank, with a copy of the original with respect to
all required insurance coverage.  Bank consents to each Borrower providing any
of the required insurance through blanket policies carried by Borrowers and
covering more than one location, provided that Borrowers furnish Bank with a
signed certificate of insurance for each such policy setting forth the
coverage, the limits of liability, the name of the carrier, the policy number,
and the expiration date.  Borrowers shall make appropriate provisions whereby
the applicable insurance carriers will furnish to Bank at least thirty (30)
days prior to the expiration of each such policy, written notice in the event
that any of the coverages required to be maintained under this Section 6.1.6
will not be renewed upon expiration and ten (10) days prior written notice of
the cancellation of all or any portion of such coverages.  All such policies,
including policies for any amounts carried in excess of the required minimum




                                     40
<PAGE>
and policies not specifically required by Bank, shall be in form reasonably
satisfactory to Bank, shall be maintained in full force and effect, shall be
delivered (or a certificate with respect thereto shall be delivered) to Bank,
shall contain a provision that such policies will not be cancelled or
materially amended, which term shall include any reduction in the scope or
limits of coverage, without at least thirty (30) days prior written notice to
Bank.  If the insurance, or any part thereof, shall expire, or be withdrawn,
or become void or unsafe by reason of any Borrower's breach of any condition
thereof, or become void or unsafe by reason of the value or impairment of the
capital of any company in which the insurance may then be carried, or if for
any reason whatever the insurance shall be unsatisfactory to Bank in its
reasonable judgment, such Borrower or Borrowers shall place new insurance
reasonably satisfactory to Bank.  Borrowers shall make appropriate provisions
with the applicable insurance carriers to name Bank as additional loss payee
for the coverages required by this Section 6.1.6.

                    6.1.6.3  In the event any Borrower fails to provide,
maintain, keep in force or deliver and furnish to Bank the policies of
insurance required by this Agreement, Bank may upon notice to the Borrower
procure such insurance or single-interest insurance for such risks covering
Bank's interest, and such Borrower will pay all premiums thereon promptly upon
demand by Bank.

                    6.1.6.4  In the event of loss in excess of $350,000 in the
case of any single incident, each affected Borrower will give immediate notice
thereof to Bank, and Bank may make proof of loss if not made promptly by such
Borrower.  Each insurance company concerned is hereby authorized and directed
to make payment under its respective policy or policies in respect of any such
loss, including return of unearned premiums, directly to Bank instead of to
such Borrower and Bank jointly, and such Borrower appoints Bank, irrevocably,
as such Borrower's attorney-in-fact to endorse any draft therefor.  Subject to
the provisions of Section 6.1.6.5 of this Agreement, Bank shall have the right
to retain and apply the proceeds of any such insurance on account of any such
loss, at its election, to reduction of the indebtedness secured hereby, or to
restoration or repair of the property damaged.  If Bank becomes the owner of
the Real Estate, or any part thereof by foreclosure or otherwise, such
policies, including all right, title and interest of the Borrowers thereunder,
shall become the absolute property of Bank.

                    6.1.6.5  Notwithstanding the provisions of Section 6.1.6.4
hereof, in the event of any damage by fire or other casualty covered by
insurance wherein the insurance proceeds are not in excess of $1,000,000, the
Bank will immediately release the insurance proceeds to the affected Borrower
for either repair or reconstruction, or both.  If the amount of the insurance
proceeds exceeds $1,000,000, such proceeds shall be made available to the
affected Borrower for such purposes upon the following terms and conditions:

                         (i)  The work will be performed by a reputable
general contractor satisfactory to Bank in the exercise of reasonable business




                                     41
<PAGE>
judgment, pursuant to plans and specifications satisfactory to Bank, in the
exercise of reasonable business judgment.

                        (ii)  The insurance proceeds will be held by Bank (or
at the request of either the Bank or the affected Borrower by an escrowee
satisfactory to Bank and such Borrower) in trust, to be disbursed periodically
as the work progresses in amounts not exceeding 90% of the value of labor and
materials incorporated into the work.  The remaining 10% will be released to
such Borrower upon final completion of the work in accordance with the
aforesaid plans and specifications, and upon a receipt of a release of liens
from all contractors and subcontractors engaged in the work.

                       (iii)  If the entire insurance proceeds are not used
for restoration, the excess proceeds shall be disbursed to such Borrower.  If
the cost of the work will exceed the available insurance proceeds, the
affected Borrower will pay for restoration work in an amount equal to such
excess prior to the disbursement of the insurance proceeds.

                        (iv)  Notwithstanding the foregoing, if at the time of
occurrence there exists an Event of Default, this subsection shall not apply
and the provisions of Section 6.1.6.4 above, shall apply instead and if at the
time of the occurrence an Unmatured Event of Default exists the proceeds shall
be held by the Bank until the same either is cured or becomes an Event of
Default.

               6.1.7  Defense of Actions.  Promptly defend all actions,
proceedings or claims affecting the Borrowers or any Borrower or its or their
business property which, if adversely determined, could cause a Materially
Adverse Effect on Borrowers or such Borrower and promptly notify Bank of the
institution of, or any change in, any such action, proceeding or claim
(except in the case of a workers compensation or general liability claim) if
the same is in excess of $75,000 for any single action, proceeding or claim
and $350,000 in the aggregate, or would have a Materially Adverse Effect on
the financial condition of Borrowers or such Borrower or its or their
property, if adversely determined;

               6.1.8  Maintenance of Assets.  Maintain, preserve, protect and
keep in good order and condition all of the Collateral and all other property
used or useful in the conduct of each Borrower's business and, from time to
time, make all necessary or appropriate repairs, replacements and improvements
thereto;

               6.1.9  Further Assurances.  Provide Bank at any time or from
time to time on request with such mortgages, assignments, certificates of
title or Financing Statements and such additional instruments or documents as
Bank may, in Bank's sole discretion, deem necessary in order to perfect,
protect and maintain the security interest in and lien on the Collateral
granted to Bank pursuant to the terms hereof and the other Loan Documents;

               6.1.10  Notice of Events.  Promptly give written notice to Bank




                                     42
<PAGE>
of the occurrence of any Event of Default and any event which causes any
representation or warranty made in Article 5 hereof to be untrue at any time
or which would cause Borrowers or any Borrower to be in default hereunder,
under the Notes or any other Loan Document for any other reason, or of any
material casualty to any of Borrowers' or such Borrower's assets;

               6.1.11  Compliance with Agreements.  Comply in all material
respects with all material agreements (including, but not limited to,
collective bargaining agreements with all labor unions) to which any Borrower
is a party the failure to do so could result in a Materially Adverse Effect.

               6.1.12  ERISA.  Comply in all material respects with the
requirements of ERISA applicable to any employee pension benefit plan (within
the meaning of Section 3(2) of ERISA), sponsored by Borrowers or any Borrower.
With respect to any such plan, other than any "multiemployer plan" (within the
meaning of Section 3(37) of ERISA), in the case of a "reportable event" within
the meaning of Section 4043 of ERISA and the regulations thereunder for which
the 30-day notice requirement has not been waived, or in the case of any other
event or condition which presents a material risk of the termination of any
such plan by action of the PBGC, Borrowers, or any Borrower, Borrowers shall
furnish to Bank a certificate of the chief financial officer of U.S. Lime
identifying such reportable event or such other event or condition and setting
forth the action, if any, that Borrowers or such Borrower intends to take or
has taken with respect thereto, together with a copy of any notice of such
reportable event or such other event or condition filed with the PBGC or any
notice received by Borrowers or such Borrower from the PBGC evidencing the
intent of the PBGC to institute proceedings to terminate any such plan.  Such
certificate of the chief financial officer or such other notice to be
furnished to Bank in accordance with the preceding sentence shall be given in
the manner provided for in Section 9.3 hereof:  (i) within 30 days after any
Borrower knows of such reportable event or such other event or condition; (ii)
as soon as possible upon receipt of any such notice from the PBGC; or (iii)
concurrently with the filing of any such notice with the PBGC, as the case may
be.  For purposes of this Section, Borrowers shall be deemed to have all
knowledge attributable to the administrator of any such plan.

               6.1.13  Financial Covenants.  Comply with the following
financial covenants:

                    6.1.13.1  Minimum Net Worth.  Maintain at all times a

under this Section 6.1.13.1 during the immediately preceding Calendar Quarter

of title with respect thereto.

               6.1.15  Mortgages.  Perform, as and when due, all of such
Borrower's obligations (both monetary and non-monetary) under all mortgages
and deeds of trust that encumber any part of the Real Estate but are not one
of the Loan Documents, within such applicable notice or cure period as may be
allowed such Borrower pursuant to the relevant mortgage or deed of trust, and
pay and discharge, at or before maturity, all of such Borrower's material
obligations and liabilities under such mortgages and deeds of trust, except

of any of the same.

               6.1.16  Notice of Changes.  Immediately upon learning of the
same notify Bank of: (i) the occurrence or imminent occurrence of any event

books and records from time to time, including without limitation, audits of
the Permits, and reimburse Bank's expenses and fees therefor for one such

department personnel to perform such audits, but in the event Bank desires, or




                                     44
<PAGE>
is required, to employ independent auditors, the reimbursable costs for such

suits, claims, or demands, including all reasonable counsel fees incurred in
investigating, evaluating or defending such claim, suffered by any of them and
caused by, relating to, arising out of, resulting from, or in any way
connected with the gross negligence or willful misconduct of such Borrower
under this Agreement, the Notes, or any other Loan Documents and any
transaction contemplated herein or therein (other than actions also arising
out of or connected with the willful misconduct or gross negligence of Bank or
actions brought in good faith by Borrowers against Bank), including, but not
limited to, claims based upon any act or failure to act by Bank in connection
with any Loan Document and any transaction contemplated therein.  If any
Borrower shall have knowledge of any claim or liability hereby indemnified
against, it shall give prompt written notice thereof to Bank.  THIS COVENANT
SHALL SURVIVE PAYMENT OF THE INDEBTEDNESS.

               6.2.1  Bank shall give Borrowers prompt notice of all suits or
actions instituted against Bank with respect to which Borrowers have
indemnified Bank, and Borrowers shall timely proceed to defend any such suit
or action.  Bank shall also have the right, at Bank's expense to participate
in or, at Bank's election, if Borrowers have not timely defended such suit or
action to assume the defense or prosecution of such suit, action, or
proceeding, and in the latter event Borrowers may employ counsel and
participate therein.  If Bank assumes the defense of any suit or action under
the terms hereof, Bank shall have the right to adjust, settle, or compromise
any claim, suit, or judgment after notice to Borrowers, and the right of Bank
to indemnification under this Agreement shall extend to any money paid by the
Bank in settlement or compromise of any such claims, suits, and judgments in
good faith, after notice to Borrowers.  The Bank will not adjust, settle or
compromise any claim or suit involving an allegation of fraud, breach of
fiduciary duty, criminal activity or other misconduct on the part of a
Borrower or any of its directors or officers without the written consent of
the Borrower which consent shall not be unreasonably withheld.

               6.2.2  If any suit, action, or other proceeding is brought by
Bank against any Borrower or Borrowers for breach of its or their covenant of
indemnity herein contained, separate suits may be brought as causes of action
accrue, without prejudice or bar to the bringing of subsequent suits on any
other cause or causes of  action, whether theretofore or thereafter accruing.

prosecute the same to completion with diligence and continuity; or a failure
by a Borrower to observe or perform any material agreement, condition,
undertaking or covenant in any other instrument evidencing or securing payment

capital stock, which consent the Bank will not unreasonably withhold;

          8.2  Remedies on Default.  Upon the occurrence and during the
continuation of any Event of Default, Bank may forthwith declare all
Indebtedness to be immediately due and payable, without protest, demand or
other notice (which are hereby expressly waived by Borrowers) and, in addition
to the rights specifically granted hereunder or now or hereafter existing in
equity, at law, by virtue of statute or otherwise (each of which rights may be
exercised at any time and from time to time), may exercise the rights and
remedies available to Bank at law or in equity or under this Agreement, the
Notes and any of the other Loan Documents or any other agreement between
Borrowers and Bank in accordance with the respective provisions thereof.

          8.3  Assembly of Collateral.  Upon the occurrence and during the

Estate, to vacate each premises upon thirty day's written notice.  Each
Borrower will pay, as part of the Indebtedness and obligations hereby secured,
all amounts (including but not limited to Bank's reasonable attorneys' fees,
where permitted by applicable law) reasonably incurred by the Bank: (i) for
taxes, levies, and insurance on, or maintenance of, such Collateral; and (ii)
in taking possession of, disposing of, or preserving such Collateral, with
interest on all of same at the Base Rate plus 3.5% following demand for the
payment thereof until paid.  The requirement of reasonable notice of the time
and place of disposition of such Collateral by Bank shall be conclusively met
if such notice is personally delivered, delivered by overnight courier,
facsimile telecopied or mailed, postage prepaid, to such Borrower's address as
specified in this Agreement at least ten days before the time of the sale or
disposition.  Bank may bid upon and purchase any or all of such Collateral at
any public sale thereof.  Bank may dispose of all or any part of such
Collateral in one or more lots or parcels and at one or more times and from
time to time, and upon such terms and conditions, including a credit sale, as
it determines in its sole discretion.  Bank shall apply the net proceeds of
any such disposition of such Collateral or any part thereof, after deducting
all costs of Bank incurred in connection therewith, or incidental to the
holding, preparing for sale, in whole or part, of the Collateral, including
attorneys' fees, and with interest thereon at the Base Rate plus 3% in such
order as Bank may elect, to the Indebtedness and obligations secured
hereunder, subject to the provisions of this Agreement, whereupon the




                                     50
<PAGE>
remaining proceeds shall be paid to such Borrower or any other party
entitled thereto.

          8.4  Set-Off Rights Upon Default.  Upon the occurrence and during
the continuance of any Event of Default, in addition to any remedies set forth
above, Bank shall have the right at any time and from time to time without
notice to Borrowers (any such notice being expressly waived by Borrowers), and
to the fullest extent permitted by applicable Rules, to set off, to exercise
any banker's lien or any right of attachment or garnishment and apply any and
all balances, credits, deposits (time or demand, provisional or final),
accounts or monies at any time held by Bank and other indebtedness at any time
owing by Bank to or for the account of Borrowers, against any and all
Indebtedness or other obligations of Borrowers now or hereafter existing under
this Agreement or any other Loan Document, whether or not Bank shall have made
any demand hereunder or thereunder.

          8.5  Singular or Multiple Exercise; Non-Waiver.  The remedies
provided herein, and in each of the other Loan Documents, or otherwise
available to Bank at law or in equity and any warrants of attorney therein
contained, shall be cumulative and concurrent, and may be pursued singly,
successively or together at the sole discretion of Bank, and may be exercised
as often as occasion therefor shall occur; and the failure to exercise any
such right or remedy shall in no event be construed as a waiver or release of
the same.

     9.  MISCELLANEOUS

          9.1  Integration.  This Agreement and the other Loan Documents shall

                                 TERM NOTE


$15,000,000                                                 December 30, 1997

     FOR VALUE RECEIVED, UNITED STATES LIME & MINERALS, INC., a Texas 
corporation (formerly known as Scottish Heritable, Inc.), TEXAS LIME COMPANY, 
a Texas corporation, and ARKANSAS LIME COMPANY, an Arkansas corporation 
(collectively referred to herein as "Borrowers"), jointly and severally 
promise to pay to the order of CORESTATES BANK, N.A., a national banking 
association, its successors and assigns ("Bank"), the principal sum of Fifteen
Million Dollars ($15,000,000) together with interest thereon at (i) with
respect to Base Rate Loans, the Base Rate per annum, (ii) with respect to 
Adjusted LIBOR Loans, the Adjusted LIBOR per annum on the relevant Interest 
Rate Determination Date plus one and sixty-five one-hundredths of a percent 
(1.65%), and (iii) with respect to Fixed Rate Loans, the Fixed Rate per annum,
payable in accordance with Section 2.1 of the Amended and Restated Loan and 
Security Agreement dated of even date herewith (the "Loan Agreement") by and 
among Bank and Borrowers. 

     This Amended and Restated Term Note (this "Term Note") replaces 
Borrowers' Term Note dated October 20, 1993 in the original principal amount 
of $8,000,000, but does not evidence repayment thereof.  This Term Note is 
issued pursuant to and entitled to the benefits of the Loan Agreement to which
reference is hereby made for a more complete statement of the terms and
conditions with respect hereto.  All initially capitalized terms not otherwise
defined herein shall have the same meanings as ascribed to them in the Loan
Agreement unless the context clearly requires to the contrary.

     Principal shall be paid in 59 equal monthly installments of $178,571 
each, commencing on the date  (the "Term Loan Amortization Date") that is the 
earlier of: (i) the date that construction is completed and Borrowers commence
pyro-processing of limestone for commercial sale from the modified number 6
kiln located at Cleburne, Johnson County, Texas, or (ii) July 1, 1998, with a 
final balloon payment of the remaining outstanding principal balance of the 
Term Loan, together with all accrued and unpaid interest and Bank's Costs 
pertaining thereto, due on the date that is 60 months after the Term Loan 
Amortization Date.  Each installment of principal hereunder, including the 
final balloon payment, shall be due on the first Business Day of each month.  

     Interest shall be payable on the outstanding principal balance hereof as 
set forth in Section 2.4.5 of the Loan Agreement, at the Interest Rate Option 
selected pursuant to Section 2.4.2 of the Loan Agreement.  Interest shall be 
calculated on the basis of a 360 day year, and charged for the number of days 
actually elapsed during any year or part thereof.

     This Term Note may be prepaid at the times, in the amounts and with the 
prepayment premiums set forth in Section 2.4.8 of the Loan Agreement.   

                                         


<PAGE>
     All payments of principal, interest, and fees hereunder shall be made by
Borrowers jointly and severally without defense, set off, or counterclaim and 
in same day funds and delivered to Bank not later than 12:00 noon 
(Philadelphia time) on the date due at Bank's office located at 1339 Chestnut 
Street, Transportation, Leasing and Construction Industry Services, 11th 
Floor, Widener Building, FC #1-8-11-24, Philadelphia, PA 19101, or such other 
place as shall be designated in writing for such purpose in accordance with 
the terms of the Loan Agreement.  

     Each Borrower authorizes Bank to charge such Borrower's demand deposit 
account with Bank in order to cause timely payment to be made to Bank of all 
principal, interest and fees hereunder as provided in Section 1.5 of the Loan 
Agreement.

     Whenever any payment on this Term Note shall be stated to be due on a 
day which is not a Business Day, such payment shall be made on the next 
succeeding Business Day and such extension of time shall be included in the 
computation of interest on this Term Note.  

     Any principal payment hereon not paid when due, and to the extent 
permitted by applicable law, any interest payment hereon not paid when due, 
and any other amount due to Bank hereunder, under the Loan Agreement or under 
any other Loan Document not paid when due, in any case whether at stated 
maturity, by notice of prepayment, by acceleration or otherwise, shall 
thereafter bear interest payable upon demand at a rate which is, with respect 
to Adjusted LIBOR Loans only, 5% per annum in excess of the Adjusted LIBOR 
until the expiration of the then applicable Interest Period, and after the 
expiration of the then applicable Interest Period, and in all cases with 
respect to Base Rate Loans and Fixed Rate Loans, at a rate which is 3% per 
annum in excess of the Base Rate.

     It shall be an event of default hereunder if an Event of Default shall 
have occurred under the Loan Agreement (a "Default").  In addition to other 
remedies of Bank as set forth in this Term Note, the Loan Agreement, or any 
other Loan Document, upon the occurrence of a Default which shall be 
continuing, Bank may, without demand, by written notice to Borrowers, cause 
this Term Note to become immediately due and payable in the manner, upon the 
conditions and with the effect provided in the Loan Agreement.

     THE FOLLOWING SETS FORTH A WARRANT OF ATTORNEY TO CONFESS JUDGMENT 
AGAINST BORROWERS OR ANY BORROWER. IN GRANTING THIS WARRANT OF ATTORNEY TO 
CONFESS JUDGMENT AGAINST BORROWERS OR ANY BORROWER, EACH BORROWER, FOLLOWING 
CONSULTATION WITH (OR DECISION NOT TO CONSULT WITH) SEPARATE COUNSEL FOR SUCH

BORROWER WAIVES ALL RELIEF FROM ANY AND ALL APPRAISEMENT OR EXEMPTION LAWS NOW
IN FORCE OR HEREAFTER ENACTED.  IF A COPY OF THIS NOTE, VERIFIED BY AFFIDAVIT 
OF AN OFFICER OF BANK OR ANY OTHER HOLDER HEREOF, SHALL BE FILED IN ANY 
PROCEEDING OR ACTION WHEREIN JUDGMENT IS TO BE CONFESSED, IT SHALL NOT BE 
NECESSARY TO FILE THE ORIGINAL HEREOF AND SUCH VERIFIED COPY SHALL BE 
SUFFICIENT WARRANT FOR ANY ATTORNEY OF ANY COURT OF RECORD TO APPEAR FOR AND 
CONFESS JUDGMENT AGAINST EACH BORROWER AS PROVIDED HEREIN.  JUDGMENT MAY BE 
CONFESSED FROM TIME TO TIME UNDER THE AFORESAID POWERS WHICH SHALL NOT BE 
EXHAUSTED BY ONE EXERCISE THEREOF.

     Borrowers hereby individually and collectively waive presentment, demand 
for payment, notice of dishonor, protest or notice of protest and any and all
notices or demands and, to the full extent permitted by law, the right to
plead any statute of limitations as a defense to any demand hereunder in 
connection with the delivery, acceptance or performance of this Term Note.

     The joint and several liabilities and obligations of Borrowers hereunder 
shall be unconditional without regard to the liability or obligations of any 
other party and shall not be in any manner affected by any indulgence 
whatsoever granted or consented to by Bank, including, but not limited to, any
extension of time, renewal, waiver or other modification.  Any failure of Bank
to exercise any right hereunder shall not be construed as a waiver of the 
right to exercise the same or any other right at any time and from time to 
time thereafter.

     This Term Note shall be governed as to its validity, interpretation and 
effect by the internal laws of the Commonwealth of Pennsylvania.  Any and all 
actions at law or in equity relating to this Term Note and the Indebtedness 
shall be brought, and jurisdiction may be had, in the courts of Philadelphia 
County, Pennsylvania, or at the election of the holder hereof, the United 
States District Court for the Eastern District of Pennsylvania.  Borrowers 

                                    (3)

requested, to the address set forth in Section 9.3 of the Loan Agreement.     
 

     EACH BORROWER AND BANK EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY 
ACTION BROUGHT BY ANY PARTY WITH RESPECT TO THE INDEBTEDNESS OR ANY LOAN 
DOCUMENT.\

     This Term Note may not be changed or amended orally but only by an 
agreement in writing and signed by the party against whom enforcement of any 
waiver, change, modification or discharge is sought.

    This Term Note is secured by and entitled to the benefits of certain 
other Loan Documents.  If any provision of this Term Note shall for any reason
be held to be invalid or unenforceable, such invalidity or unenforceability

                                    NOTE

$4,000,000                                                  December 30, 1997
 
     FOR VALUE RECEIVED, UNITED STATES LIME & MINERALS, INC., a Texas 
corporation (formerly known as Scottish Heritable, Inc.), TEXAS LIME COMPANY, 
a Texas corporation, and ARKANSAS LIME COMPANY, an Arkansas corporation 
(collectively referred to herein as "Borrowers"), jointly and severally 
promise to pay to the order of CORESTATES BANK, N.A., a national banking 
association, its successors and assigns ("Bank"), the lesser of (x) Four 
Million Dollars ($4,000,000) or (y) the aggregate unpaid principal amount of 
all Cash Advances made by Bank to Borrowers or any Borrower under the Amended 
and Restated Loan and Security Agreement of even date herewith, by and among 
Borrowers and Bank ("Loan Agreement"), which principal amount and all accrued 
and unpaid interest thereon and Bank's Costs pertaining thereto shall be 
payable on the date that is 24 months after the date hereof, or such later 
date as may be agreed to in writing by Bank.  

     This Amended and Restated Note (this "Note") replaces Borrowers' Note 
dated October 20, 1993 in the original principal amount of $6,000,000, but 
does not evidence repayment thereof.  This Note is issued pursuant to and 
entitled to the benefits of the Loan Agreement to which reference is hereby 
made for a more complete statement of the terms and conditions with respect 
hereto.  All initially capitalized terms used herein shall have the same 
meanings as ascribed to them in the Loan Agreement unless the context clearly 
requires to the contrary.

     Borrowers promise to pay interest on the unpaid principal amount of all 
Cash Advances from the date made to maturity (whether by acceleration or 
otherwise) or earlier repayment, with respect to Base Rate Loans at the Base 
Rate per annum, and with respect to Adjusted LIBOR Loans at the Adjusted LIBOR
on the relevant Interest Rate Determination Date plus 1.5% per annum, payable 
in accordance with Section 2.2 of the Loan Agreement. 

     Interest shall be payable on the outstanding principal balance hereof as 
set forth in Section 2.4.5 of the Loan Agreement, at the Interest Rate Option 
selected pursuant to Section 2.4.2 of the Loan Agreement.  Interest shall be 
calculated on the basis of a 360 day year, and charged for the number of days 
actually elapsed during any year or part thereof.

     This Note may be prepaid at the times, in the amounts and with the 
prepayment premiums set forth in Section 2.4.8 of the Loan Agreement.   

     All payments hereunder shall be made by Borrowers jointly and severally 
without defense, set off, or counterclaim and in same day funds and delivered 
to Bank not later than 12:00 noon (Philadelphia time) on the date due at 
Bank's office located at 1339 Chestnut Street, Transportation, Leasing and 

                                      1
<PAGE>
Construction Industry Services, 11th Floor, Widener Building, FC #1-8-11-24,
Philadelphia, PA 19101, or such other place as shall be designated in writing 
for such purpose in accordance with the terms of the Loan Agreement.  

     Each Borrower authorizes Bank to charge such Borrower's demand deposit 
account with Bank in order to cause timely payment to be made to Bank of all 
principal, interest and fees hereunder as provided in Section 1.5 of the Loan 
Agreement.

     Whenever any payment on this Note shall be stated to be due on a day 
which is not a Business Day, such payment shall be made on the next succeeding
Business Day and such extension of time shall be included in the computation 
of interest on this Note.

     Any principal payment hereon not paid when due, and to the extent 
permitted by applicable law, any interest payment hereon not paid when due, 
and any other amount due to Bank hereunder, under the Loan Agreement or under 
any other Loan Document not paid when due, in any case whether at stated 
maturity, by notice of prepayment, by acceleration or otherwise, shall 
thereafter bear interest payable upon demand at a rate which is, with respect 
to Adjusted LIBOR Loans only, 5% per annum in excess of the Adjusted LIBOR 
until the expiration of the then applicable Interest Period, and after the 
expiration of the then applicable Interest Period, and in all cases with 
respect to Base Rate Loans, at a rate which is 2.75% per annum in excess of 
the Base Rate.

     It shall be an event of default hereunder if an Event of Default shall 
have occurred under the Loan Agreement (a "Default").  In addition to other 
remedies of Bank as set forth in this Note, the Loan Agreement, or any other 
Loan Document, upon the occurrence of a Default which shall be continuing, 
Bank may, without demand, by written notice to Borrowers, cause this Note to 
become immediately due and payable in the manner, upon the conditions and with 
the effect provided in the Loan Agreement.

     THE FOLLOWING SETS FORTH A WARRANT OF ATTORNEY TO CONFESS JUDGMENT 
AGAINST BORROWERS OR ANY BORROWER. IN GRANTING THIS WARRANT OF ATTORNEY TO 
CONFESS JUDGMENT AGAINST BORROWERS OR ANY BORROWER, EACH BORROWER, FOLLOWING 
CONSULTATION WITH (OR DECISION NOT TO CONSULT WITH) SEPARATE COUNSEL FOR SUCH

PROCEEDING OR ACTION WHEREIN JUDGMENT IS TO BE CONFESSED, IT SHALL NOT BE 
NECESSARY TO FILE THE ORIGINAL HEREOF AND SUCH VERIFIED COPY SHALL BE

The joint and several liabilities and obligations of Borrowers hereunder shall
be unconditional without regard to the liability or obligations of any other
party and shall not be in any manner affected by any indulgence whatsoever 
granted or consented to by Bank, including, but not limited to, any extension 
of time, renewal, waiver or other modification.  Any failure of Bank to
