The Capital Expenditure Loans shall be evidenced by the (i) Five

($5,000,000.00) Note of Borrower to NationsBank of Tennessee,
N.A., and (ii) the Five Million
Dollars ($5,000,000.00) Note of Borrower to Chemical Bank, which
Notes are substantially in

been satisfied.  Furthermore, it shall be a condition precedent

                    (2)  Borrower shall have submitted evidence
satisfactory to the
Banks that The Feldspar Corporation has paid for the first Two
Million Five Hundred Thousand

initial draw request, as well as each subsequent draw request,
shall be submitted on the Capital
Expenditure Draw Request Form attached hereto as Exhibit B, which
form shall be completed
and signed by a Borrower.  Borrower shall not be entitled to draw
for or request reimbursement
for its Renovation Equity; provided, upon final completion of all
improvements contemplated
by the Renovation Costs budget, if savings are realized such that
the final Renovation Costs are
less than Twelve Million Five Hundred Thousand Dollars
($12,500,000.00), then the Borrower
may in its final draw request (which must be made prior to April
1, 1996) include a request for
reimbursement of a portion of its Renovation Equity equal to that
amount by which $12,500,000
exceeds the final expended Renovation Costs, but not to exceed in
any event a maximum of Two
Million Five Hundred Thousand Dollars ($2,500,000.00).

               (C)  The failure of any Bank to make any advances
hereunder pursuant
to its Capital Expenditure Loan Commitment shall not relieve any
other Bank of its obligation,
if any, hereunder to make its advances pursuant to its Capital
Expenditure Loan Commitment.
However, no Bank shall be responsible for any other Bank's
failure or refusal to make any
advances pursuant to such other Bank's Capital Expenditure Loan
Commitment.

               (D)  On the Capital Expenditure Loan Commitment
Termination Date,
the outstanding balance of the Capital Expenditure Loans shall be
permanently converted to non-
revolving Term Loans.  Commencing April 1, 1996, the outstanding
balance of such Term
Loans shall be payable in equal quarter-annual installments of
principal in the aggregate amount
of Two Hundred Seventy-Seven Thousand Seven Hundred Seventy-Seven
and 78/100 Dollars
($277,777.78) each, said installments to be applied pro rata to
the Notes of each Bank.  Interest
as hereinbelow set forth shall continue to be due and payable on
the principal balance from time

each such Term Loan shall be due
and payable in full in a balloon installment on the Loan
Termination Date.

the full amount of the Working Capital Loan Commitment or any
lesser sum which is in the

notice (a "Borrowing
Notice") not later than 10:00 a.m. Nashville time at least three
(3) Business Days prior to the
date of any requested disbursement of Eurodollar Loans and one
(1) Business Day prior to any
requested disbursement of Floating Rate Loans.  Each Borrowing
Notice shall be written and
may be made by telecopier, telex or cable in addition to the
means set forth for giving notice
in Paragraph 10.5.  Each Borrowing Notice shall specify the
funding source of the Loan, i.e.,
Revolving Loan, Capital Expenditure Loan, or Working Capital
Loan; the requested date of such
requested disbursement; the aggregate amount of such
disbursement; the type of Loan, i.e.,
Eurodollar or Floating Rate; and if a Eurodollar Loan, the
designated Interest Period.  The
Agent shall promptly advise the other Banks of any Borrowing
Notice given pursuant to this
Section and each Bank's portion of the requested Loan.  Not later
than noon (12:00 a.m.)
Nashville time on each disbursement date, and subject to the
terms and conditions hereof, Agent
will credit the proceeds of the Loans received by Agent from the
Banks to the Borrower's
deposit account with Agent.  Each such Borrowing Notice shall
obligate the Borrower to accept
the Loan disbursement requested thereby.

               (C)  The Borrower shall have the right at any
time, on prior irrevocable
written or telex notice to the Agent not later than 10:00 a.m.,
Nashville time, three (3) Business
Days prior to the date of any requested conversion, to convert
any Floating Rate or Eurodollar
Loan into a Loan of another type, or to continue any Eurodollar
Loan for another Interest Period
(specifying in each case the Interest Period to be applicable
thereto), subject in each case to the
following:

                    (1)  Each conversion or continuation shall be
made prorata
among the Banks in accordance with the respective principal
amounts of the Loan converted or
continued;

                    (2)  No Eurodollar Loan shall be converted at
any time other
than at the end of the Interest Period applicable thereto;

                    (3)  Each conversion shall be effected by
applying the proceeds
of the new Eurodollar and/or Floating Rate Loan, as the case may
be, to the Loan (or portion
thereof) being converted;

                    (4)  The number of Eurodollar Loans
outstanding at one time
may not exceed seven (7); and

                    (5)  No Interest Period may be selected for
any Eurodollar Loan
that would end later than a repayment date occurring on or after
the first day of such Interest
Period if the aggregate outstanding amount of Eurodollar Loans
with Interest Periods ending
prior to such repayment date plus the aggregate outstanding
amount of all Floating Rate Loans
is not equal to or greater than the principal amount(s) of the
Loan(s) to be paid on such
repayment date.

               (D)  Each notice pursuant to this Paragraph shall
be irrevocable and shall
refer to this Agreement and specify (1) the identity and
principal amount of the particular Loan
that the Borrower requests be converted or continued, (2) if such
notice requests conversion, the
date of such conversion (which shall be a Business Day), and (3)
if a Loan is to be converted
to a Eurodollar Loan or a Eurodollar Loan is to be continued, the
Interest Period with respect
thereto.  In the event that the Borrower shall not give notice to
continue any Eurodollar Loan
for a subsequent period, such Eurodollar Loan (unless repaid)
shall automatically be converted
into a Floating Rate Loan.  If the Borrower shall fail to specify
in any Borrowing Notice the
type of borrowing or, in the case of a Eurodollar Loan, the
applicable Interest Period, the
Borrower will be deemed to have requested a Floating Rate Loan.
If Agent reasonably believes
that any failure by Borrower to specify the type of borrowing or
the applicable Interest Period
shall have resulted from failure of communications equipment or
clerical error, then prior to
funding any such borrowing the Agent shall use reasonable efforts
to obtain confirmation from
Borrower of the contents of such Borrowing Notice; however, in
the absence of prompt
confirmation by Borrower which specifies the type of borrowing
and/or the applicable Interest
Period, the Borrower will be deemed to have requested a Floating
Rate Loan.  Notwithstanding
anything to the contrary contained above, if an Event of Default
shall have occurred and be
continuing, no Eurodollar Loan may be continued and no Floating
Rate Loan may be converted
into a Eurodollar Loan.

               (E)  Interest shall be charged and paid on each
Loan from the date of
the initial advance thereunder until such Loan is paid or
converted as follows:

                    (1)  For a Floating Rate Loan, at an annual
rate equal to the
Prime Rate plus the Applicable Prime Rate Margin, said rate to
change contemporaneously with
any change in the Prime Rate.

                    (2)  For a Eurodollar Loan, at a rate equal
to the LIBO Rate plus
the Applicable LIBO Rate Margin.

                    (3)  The Borrower shall pay to any Bank, if
and so long as such
Bank shall be required under regulations of the Board of
Governors of the Federal Reserve
System to maintain reserves with respect to liabilities or assets
consisting of or including
Eurodollar Liabilities, additional interest on the unpaid
principal amount of each Eurodollar
Loan, from the date of such advance until said principal amount
is paid in full, at an interest rate
per annum equal at all times to the remainder obtained by
subtracting (i) the LIBO Rate for the
Interest Period from (ii) the rate obtained by dividing the LIBO
Rate by a percentage equal to
100% minus the Eurodollar Rate Reserve Percentage for such
Interest Period, payable on each
date on which interest is payable.  Such additional interest
shall be determined by such Bank
who shall notify Borrower thereof; however, such additional
interest shall be payable only if the
condition of Paragraph 2.10(C)(2) is satisfied.

                    (4)  Interest for both Floating Rate Loans
and Eurodollar Loans
shall be computed on the basis of a 360-day year counting the
actual number of days elapsed,
and shall be due and payable without notice on each Interest
Payment Date.

               (F)  Notwithstanding the foregoing, upon the
occurrence of an Event
of Default interest shall be charged at the Default Rate as
defined and set forth in the Notes,
regardless of whether the Majority Banks have elected to exercise
any other remedies under
Section VIII hereof, including without limitation acceleration of
the maturity of the outstanding
principal of the Notes.  All such interest shall be paid at the
time of and as a condition precedent
to the curing of any such default to the extent any right to cure
is given.

               (G)  All agreements herein made are expressly
limited so that in no
event whatsoever shall the interest and loan charges agreed to be
paid to the Banks for the use
of the money advanced or to be advanced pursuant to this
Agreement exceed the maximum
amounts collectible under applicable laws in effect from time to
time.  If for any reason
whatsoever the interest or loan charges paid or contracted to be
paid in respect of the Loans
shall exceed the maximum amounts collectible under applicable
laws in effect from time to time,
then, ipso facto, the obligation to pay such interest and/or loan
charges shall be reduced to the
maximum amounts collectible under applicable laws in effect from
time to time, and any
amounts collected by the Banks that exceed such maximum amounts
shall be applied to the
reduction of the principal balance of the Loans and/or refunded
to Borrower so that at no time
shall the interest or loan charges paid or payable in respect of
the Loans exceed the maximum
amounts permitted from time to time by applicable law.  This
provision shall control every other
provision herein and in any and all other agreements and
instruments now existing or hereafter
arising between Borrower and the Banks with respect to the Loans.

          2.5  Facility Fee.  A facility fee of One Hundred Fifty-
One Thousand One
Hundred Twenty-Two and 50/100 Dollars ($151,122.50) shall be due
and payable in full at
Closing to the Banks in the following amounts:  NationsBank of
Tennessee, N.A., $88,061.25,
and Chemical Bank, $63,061.25.

          2.6  Nonusage Fee.  With respect to each of the
Revolving Loan Commitments,
the Capital Expenditure Loan Commitments, and the Working Capital
Commitment, from and
after the date hereof until the respective Commitment Termination
Date, the Borrower shall pay
to the Agent for the account of the Banks a nonusage fee of three-
eighths of one percent
(0.375%) per annum on the average daily undisbursed amount of
each of the Commitments
during each quarter-annual period or portion thereof.  This
nonusage fee shall be payable
quarter-annually in arrears, on the first day of each January 1,
April 1, July 1, and October 1,
commencing April 1, 1995.  Any accrued and unpaid nonusage fee on
any Commitment shall
be paid on its respective Commitment Termination Date.

          2.7  Agent's Fee.  An agent's fee of Twenty Thousand
Dollars ($20,000.00)
per annum shall be due and payable by Borrower to the Agent
annually commencing
December 31, 1995 and each December 31 thereafter.

          2.8  Reduction of Commitment.  The Borrower shall have
the right to reduce
the amount of the Total Commitments, at any time and from time to
time, in any integral
multiple of Two Hundred Fifty Thousand Dollars ($250,000.00),
which reduction shall, unless
otherwise agreed in writing, reduce each Bank's Commitment pro
rata in accordance with its
Commitment Percentage; provided, if the request for reduction is
made after the Capital
Expenditure Loan Commitment Termination Date and/or the Working
Capital Loan Termination
Date, then it shall reduce pro rata only those Commitments of
each Bank as are still outstanding.
Contemporaneously with each such reduction, the Borrower shall
repay to the Agent for the
account of each Bank in accordance with its respective Commitment
Percentage the amounts,
if any, by which the then outstanding principal balance of each
Note exceeds each Commitment
as so reduced.  After each such reduction:  (i) the Borrower
shall immediately pay the Agent
any nonusage fee provided for in Paragraph 2.6 with respect to
the amount by which the Total
Commitments are so reduced, but only with respect to the time any
such Commitment existed
and only to the extent not previously paid; (ii) the nonusage fee
provided for in Paragraph 2.6
shall be calculated with respect to the Total Commitments as so
reduced; and (iii) the Total
Commitments may not be increased without the written consent of
the Banks.

          2.9  Alternate Rate of Interest.

               (A)  In the event, and on each occasion, that on
the date of
commencement of any Interest Period for a Eurodollar Loan, any
Bank shall have determined:

                    (1)  That dollar deposits in the amount of
the requested principal
amount of such Eurodollar Loan are not generally available in the
London Interbank Market;

                    (2)  That the rate at which such dollar
deposits are being offered
will not adequately and fairly reflect the cost to Bank of making
or maintaining such Eurodollar
Loan during such Interest Period; or

                    (3)  That reasonable means do not exist for
ascertaining the
LIBO Rate,

such Bank shall, as soon as practicable thereafter, give written
or telephonic notice of such
determination to the Borrower.  In the event of any such
determination, any request by the
Borrower for a Eurodollar Loan pursuant to Paragraph 2.4 shall,
until the circumstances giving
rise to such notice no longer exist, be deemed to be a request
for a Floating Rate Loan.  Each
determination by a Bank hereunder shall be conclusive absent
manifest error.

          2.10 Change in Circumstances.

               (A)  Notwithstanding any other provision herein,
if after the date of this
Agreement any change in applicable Laws or regulation or in the
interpretation or administration
thereof by any governmental authority charged with the
interpretation or administration thereof
(whether or not having the force of law) shall change the basis
of taxation of payments to a Bank
under any Eurodollar Loan made by a Bank or any other fees or
amounts payable hereunder
(other than taxes imposed on the overall net income of such Bank
by the country in which such
Bank is located, or by the jurisdiction in which such Bank has
its principal office, or by any
political subdivision or taxing authority therein), or shall
impose, modify or deem applicable any
reserve requirement, special deposit, insurance charge (including
FDIC insurance on Eurodollar
deposits) or similar requirement against assets of, deposits with
or for the account of, or credit
extended by, such Bank or shall impose on such Bank or the London
Interbank Market any other
condition affecting this Agreement or Eurodollar Loans made by
such Bank, and the result of
any of the foregoing shall be to increase the cost to such Bank
of making or maintaining any
Eurodollar Loan or to reduce the amount of any sum received or
receivable by such Bank here-
under (whether of principal, interest or otherwise) in respect
thereof by an amount deemed by
such Bank to be material, then the Borrower will pay to such Bank
such additional amount or
amounts as will compensate such Bank for such additional costs of
reduction.

               (B)  If either:

                    (1)  The introduction of, or any change in,
or in the
interpretation of, any United States or foreign law, rule or
regulation; or

                    (2)  Compliance with any directive,
guidelines or request from
any central bank or other United States or foreign governmental
authority (whether or not having
the force of law) promulgated or made after the date hereof (but
excluding, however, any law,
rule, regulation, interpretation, directive, guideline or request
contemplated by or resulting from
the report dated July, 1988, entitled "International Convergence
of Capital Measurement and
Capital Standards" issued by the Basle Committee on Banking
Regulations and Supervisory
Practices),

affects or would affect the amount of capital required or
expected to be maintained by a Bank
(or any lending office of such Bank) or any corporation directly
or indirectly owning or
controlling such Bank (or any lending office of such Bank) based
upon the existence of this
Agreement, and such Bank shall have determined that such
introduction, change or compliance
has or would have the effect of reducing the rate of return on
Bank's capital or on the capital
of such owning or controlling corporation as a consequence of its
obligations hereunder
(including its Commitment) to a level below that which such Bank
or such owning or controlling
corporation could have achieved but for such introduction, change
or compliance (after taking
into account that Bank's policies or the policies of such owning
or controlling corporation, as
the case may be, regarding capital adequacy) by an amount deemed
by such Bank (in its sole
discretion) to be material, then, from time to time, the Borrower
shall pay to such Bank such
additional amount or amounts as will compensate such Bank for
such reduction attributable to
making, funding and maintaining its Commitment and Loans
hereunder.

               (C)  A certificate of any Bank setting forth such
amount or amounts as
shall be necessary to compensate such Bank (or its participating
banks or other entities pursuant
to Paragraph 10.8) as specified in paragraph (A) or (B) above, as
the case may be, shall be
delivered to the Borrower and shall be conclusive absent manifest
error; provided however, that
the Borrower shall be responsible for compliance herewith and the
payment of increased costs
only to the extent:

                    (1)  Any change in Laws giving rise to
increased costs occurs
after the date of this Agreement;

                    (2)  Such change in Laws or the application
thereof applies
generally to the banking industry and is not the result of one or
more of the Banks in this
Agreement having inadequate or substandard capital as determined
by its regulators; and

                    (3)  The affected Bank gives notice of the
change giving rise to
increased costs within one hundred eighty (180) Business Days
after such Bank has, or with
reasonable diligence should have had, knowledge of the change, or
else such Bank can only
collect costs from and after the date of the notice.

Subject to the foregoing, the Borrower shall pay the affected
Bank the amount shown as due on
any such certificate within ten (10) days after its receipt of
such certificate.

               (D)  The protection of this Paragraph 2.10 shall
be available to each
Bank regardless of any possible contention of invalidity or
inapplicability of the law, regulation
or condition that shall have been imposed; provided, if a court
of competent jurisdiction (or a
final administrative proceeding which is not judicially
challenged) finally determines that such
law or regulation is invalid or unapplicable, then the protection
of this Paragraph shall not be
available.

          2.11 Change in Legality.

               (A)  Notwithstanding anything to the contrary
herein contained, if any
change in any law or regulation or in interpretation thereof by
any governmental authority
charged with the administration or interpretation thereof shall
make it unlawful for any Bank to
make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated
hereby, then, by written notice to the Borrower, such Bank may:

                    (1)  Declare that Eurodollar Loans will not
thereafter be made
by such Bank hereunder, whereupon the Borrower shall be
prohibited from requesting Eurodollar
Loans from such Bank hereunder unless such declaration is
subsequently withdrawn; and

                    (2)  Require that all outstanding Eurodollar
Loans made by it be
converted to Floating Rate Loans, in which event (a) all such
Eurodollar Loans shall be
automatically converted to Floating Rate Loans as of the
effective date of such notice as
provided in paragraph (B) below and (b) all payments and
prepayments of principal that would
otherwise have been applied to repay the converted Eurodollar
Loans shall instead be applied
to repay the Floating Rate Loans resulting from the conversion of
such Eurodollar Loans.

               (B)  For purposes of this Paragraph 2.11, a notice
to the Borrower by
any Bank pursuant to (A) above shall be effective, if lawful, on
the last day of the then current
Interest Period; in all other cases, such notice shall be
effective on the date of receipt by the
Borrower.

          2.12 Optional Prepayment - Premiums in Certain Events.

               (A)  The Borrower may, upon three (3) Business
Days' prior written
notice to the Agent, and upon payment of all premiums set forth
in subparagraph (D)
hereinbelow, prepay any outstanding Eurodollar Loans prior to any
Interest Payment Date for
such Eurodollar Loans, in whole or in part.

               (B)  The Borrower may at any time prepay any
outstanding Floating
Rate Loans in whole or in part without premium or penalty.

               (C)  Each notice of prepayment of any Eurodollar
Loan shall specify the
date and amount of such prepayment and the type of Loan (i.e.,
Revolving, Capital Expenditure,
Working Capital) to which it relates and shall be irrevocable.
The Agent shall promptly notify
the Banks of its receipt of a notice of prepayment.  Each partial
prepayment of any Eurodollar
Loans shall be in an aggregate principal amount which is the
lesser of (1) the then outstanding
principal balance of the one or more Eurodollar Loans to be
prepaid, or (2) One Hundred
Thousand Dollars ($100,000.00) or an integral multiple thereof.
Interest on the amount prepaid
accrued to the prepayment date shall be paid on such date.

               relevant Interest Payment Date for such borrowing,
Borrower shall pay to Agent for the account
of each Bank, in addition to all other payments then due and
owing the Banks, premiums which
shall be equal to an amount, if any, reasonably determined by
each Bank to be the difference
between the rate of interest then applicable to the relevant
Eurodollar Loan and the yield each
Bank receives upon reinvestment of so much of the relevant
Eurodollar Loans as is prepaid for
the remainder of the term of the relevant Eurodollar Loan or
Loans.  Anything in this section
2.12(D) to the contrary notwithstanding, the premiums payable
upon any such prepayment shall
not exceed the amount, if any, reasonably determined by each Bank
to be the difference between
the rate of interest then applicable to the relevant Eurodollar
Loan and the yield that each Bank
could receive upon reinvestment in the "Floor Reinvestment" of so
much of the relevant
Eurodollar Loan as is prepaid for the remainder of the term of
the relevant Eurodollar Loan.
For purposes hereof, "Floor Reinvestment" shall mean an
investment for the time period from
the date of such prepayment to the end of the relevant Interest
Period applicable to such
Eurodollar Loan at an interest rate per annum equal to the
federal funds "offered" rate as
published in the Wall Street Journal on the date of such
prepayment.  All determinations,
estimates, assumptions, allocations and the like required for the
determination of such premiums
shall be made by each Bank in good faith and shall be presumed
correct absent demonstrable
error.

          2.13 Payment to the Agent.

               (A)  The Agent shall send the Borrower statements
of all amounts due
hereunder (or the Banks may in the case of Section 2.10 above),
which statements shall be
considered correct and conclusively binding on the Borrower
unless the Borrower notifies the
Agent to the contrary within one hundred eighty (180) days of its
receipt of any statement to
which it objects.  All sums payable to the Banks hereunder shall
be paid directly to the Agent
for the account of each Bank in immediately available funds prior
to 12:00 noon, Nashville time,
on the date when such sums are due and payable.  Any amounts
received by the Agent after
12:00 noon Nashville time on any Business Day shall be deemed to
have been received on the
next Business Day.  Alternatively, at its sole discretion, the
Agent may charge against any
deposit account of the Borrower maintained with any of the Banks
all or any part of any amount
due pursuant to this Agreement.

               (B)  Each payment made to the Agent on the Notes
or for other sums
or fees due hereunder for the account of the Banks shall in like
funds be properly remitted by
the Agent to each Bank, no later than 2:00 p.m. Nashville time on
the date on which Agent
receives such payment; provided, payments made on the Working
Capital Note shall be remitted
solely to NationsBank of Tennessee, N.A.

                    (1)  Join with the Agent in executing such

                    (2)  Pay or reimburse the Banks for all costs

the Banks' security interest in the Collateral.

               (B)  A carbon, photographic, or other reproduction

thereof.

               (C)  To the extent lawful, the Borrower and each

appropriate to perfect and
continue the Banks' security interest in, and to protect and
preserve, the Collateral.

          4.8  Negotiation of Zemex Note.  Simultaneously with

qualification) and delivering the Zemex
Note together with all collateral documents securing the payment
of same to Agent on behalf of
the Banks.  Agent shall retain possession of the Zemex Note to
perfect the security interest of
the Banks therein.  Following the occurrence of any Event of
Default and for so long as such
Event of Default remains uncured, upon demand of the Majority
Banks the Agent may direct
the obligor of the Zemex Note to send all payments made under the
Zemex Note and to send
all notices pertaining to the Zemex Note or the collateral
securing payment of same directly and
exclusively to the Agent on behalf of the Banks as the Agent may
specify.

          4.9  Collection of Receivables.  Following the
occurrence of any Event of
Default and for so long as such Event of Default remains uncured,
upon demand of the Majority
Banks, Borrower and each Participating Subsidiary shall deposit
or cause to be deposited, all
checks, drafts, cash, and other remittances received in payment
of services rendered or inventory
sold or in payment or on account of its accounts, immediately
upon receipt thereof with Agent
in a special "lockboxed" bank account maintained with Agent, over
which the Majority Banks
alone have power of withdrawal.  The funds in said special bank
account shall be held by the
Banks as security for all loans made hereunder and all other
Obligations of Borrower to the
Banks secured hereby.  Said proceeds shall be deposited in
precisely the form received, except
for the endorsement of Borrower and each Participating Subsidiary
where necessary to permit
collection, which endorsement Borrower and each Participating
Subsidiary agree to make and
which Agent also hereby is irrevocably authorized to make on
their behalf.  Pending such
deposit, Borrower and each Participating Subsidiary agree that
they will not commingle any such
checks, drafts, cash, and other remittances with any of their
funds or property, but will hold
them separate and apart therefrom and upon an express trust for
the Banks until deposit thereof
is made in the said special bank account.  At least twice weekly,
Agent will apply the whole or
any part, as the Majority Banks deem appropriate, of the
collected funds on deposit in the said
special bank account against the principal and/or interest of any
loans made hereunder and/or
on Borrower's other Obligations secured hereby, the order and
method of such application to
be in the discretion of the Majority Banks.  Any portion of said

bank account that the Majority Banks elect not to apply will be
paid over by Agent to Borrower.

Borrower will cause each
mortgagee of all real estate owned by the Borrower or any
Participating Subsidiary, and each
landlord of all premises leased by the Borrower or any
Participating Subsidiary, to execute and
deliver to the Agent instruments, in form and substance
satisfactory to the Banks, by which such
mortgagee or landlord waives its rights, if any, to any portion
of the Collateral located on such
premises, and agrees to provide Agent notice of and an
opportunity to cure any default by
Borrower or such Participating Subsidiary under such mortgage or
lease.

               (B)  Upon Borrower's either acquiring the
Monticello, Georgia land on
which its operating plant is located or upon Borrower's
renegotiating a new lease term for said
site, Borrower shall immediately notify each Bank and provide to
each Bank a copy of the
applicable deed and/or lease.  Thereafter, Borrower agrees to
execute and deliver to the Agent
on behalf of the Banks a Georgia form of deed to secure debt in
the form previously delivered
to Bank on the other Monticello, Georgia property which deed to
secure debt will encumber
Borrower's fee simple and/or leasehold interest in the plant, as
applicable.  Borrower agrees that
such deed to secure debt shall be delivered as soon as
practicable after Borrower resolves its title
issues by either acquiring fee simple title or executing a new
lease, but in no event later than
sixty (60) days after Borrower's acquisition of the fee simple
title and/or execution of a written
lease.

Indebtedness for borrowed money
(whether direct or indirect, including Guarantee Obligations) due
any Person, except when the
amount thereof is being contested in good faith by appropriate
proceedings and with adequate
security therefor being set aside in a manner satisfactory to the
Banks.  If default is made by the
Borrower or any Participating Subsidiary in the payment of any
principal (or installment thereof)
of, or interest on, any such Indebtedness, the Banks shall have

pay such interest or principal for the account of the Borrower or
such Participating Subsidiary

such failure before the Majority Banks and/or Agent exercise the

               (M)  Pyron Corporation shall default under the
Letter of Credit Facility
or the Letter of Credit Reimbursement Agreement.

               (N)  Any Borrower or Participating Subsidiary
shall default in any other
Indebtedness (excluding the Obligations) owed to the Banks, or
any of them, or under any other
agreements for credit or borrowed money it may have with any
Bank, jointly or severally,
directly or indirectly, whether matured or unmatured.

               (O)  The occurrence of a Change of Control.

          8.2  Acceleration.  Upon the occurrence of any of such
Events of Default, the
Majority Banks may, at their option, immediately terminate the
obligation to make any further
advances under the respective Commitments and/or declare the
principal and interest accrued
on the Notes and all other Obligations to be immediately due and
payable, whereupon the same
shall become forthwith due and payable, without presentment,
demand, protest, or any notice
of any kind except as set forth above; provided, that in the case
of the Events of Default
specified in clause (G), (H) or (I) above with respect to
Borrower, without any notice to
Borrower or any act by Agent or the Banks, the Commitments shall
thereupon terminate and the
Notes and all other Obligations shall become immediately due and
payable without presentment,
demand, protest or other notice of any kind, all of which are
waived by the Borrower.  In
addition, and regardless of whether the Notes have been
accelerated, the Majority Banks may
upon the occurrence of any Event of Default elect to charge
interest at the Default Rate set forth
in the Notes.

          8.3  Remedies.  After any acceleration, as provided for
in Paragraph 8.2, the
Banks shall have, in addition to the rights and remedies given it
by the Loan Documents, all
those allowed by all applicable Laws, including, but without
limitation, the UCC as enacted in
any jurisdiction in which any Collateral may be located.  Without
limiting the generality of the
foregoing, the Banks may immediately, without demand of
performance and without other notice
(except as specifically required by the Loan Documents) or demand
whatsoever to the Borrower,
all of which are hereby expressly waived, and without
advertisement, sell at public or private
sale, in any manner and at any location authorized by Laws, or
otherwise realize upon, the
whole or, from time to time, any part of the Collateral, or any
interest which the Borrower may
have therein.  After deducting from the proceeds of  sale or
other disposition of the Collateral
all expenses (including all reasonable expenses for legal
services), the Banks shall apply such
proceeds toward the satisfaction of the Obligations.  Any
remainder of the proceeds after
satisfaction in full of the Obligations shall be distributed as
required by applicable Laws.  Notice
of any sale or other disposition shall be given to the Borrower
at least five (5) days before the
time of any intended public sale or of the time after which any
intended private sale or other
disposition of the Collateral is to be made, which the Borrower
hereby agrees shall be reasonable
notice of such sale or other disposition.  The Borrower agrees to
assemble, or to cause to be
assembled, at its own expense, the Collateral at such place or
places as the Banks shall
designate.  At any such sale or other disposition, the Banks may,
to the extent permissible under
applicable Laws, purchase the whole or any part of the
Collateral, free from any right of
redemption on the part of the Borrower, which right is hereby
expressly waived and released.

               Without limiting the generality of any of the
rights and remedies conferred
upon the Banks under this Paragraph 8.3, the Banks may, to the
full extent permitted by
applicable Laws:

               (A)  Engage independent appraisers and field
examiners, reasonably
acceptable to the Borrower, to conduct appraisals and field
examinations of the real properties,
leasehold interest, fixtures, machinery, equipment, inventory and
accounts receivable owned by
Borrower and/or any of its Participating Subsidiaries, with all
of the reasonable costs of such
appraisals and field examinations to be paid by Borrower or, if
paid by the Banks, reimbursed
to the Banks by Borrower upon demand of the Banks.  All such
field examinations and
appraisals shall be conducted in accordance with Agent's
guidelines for such appraisals and field
examinations at the time, and Borrower and each Participating
Subsidiary hereby agree that such
guidelines are reasonable;

               (B)  Enter upon the premises of the Borrower,
exclude therefrom the
Borrower, any Subsidiary or any Affiliate thereof, and take
immediate possession of the
Collateral, either personally or by means of a receiver appointed
by a court of competent
jurisdiction, using all necessary and lawful self-help to do so;

               (C)  At the Banks' option, use, operate, manage
and control the
Collateral in any lawful manner;

               (D)  Collect and receive all receivables, rents,
income, revenue,
earnings, issues and profits therefrom; and

               (E)  Maintain, repair, renovate, alter or remove
the Collateral as the
Banks may determine in their discretion.


                     SECTION IX.   THE AGENT

          This Section IX is between and among the Agent and the
Banks only.  Neither
the Borrower nor any other creditor of the Borrower shall have
any rights under this section,
whether as a third party beneficiary or otherwise, and this
section may be amended by the Agent
and the Banks acting alone.

          9.1  Authorization.  Each Bank authorizes the Agent to
act on behalf of such
Bank or holder to the extent provided herein or in any document
or instrument delivered
hereunder or in connection herewith and signed by such Bank, and
to take such other action as
may be reasonably incidental thereto.  The Agent shall be
considered as acting solely in an
administrative and ministerial capacity, not as trustee or other
fiduciary of the Banks.  The
Agent shall not be construed as having any agency or fiduciary
relationship with the Borrower.
The Agent shall not have any duties or obligations to the Banks
other than those expressly
provided for herein.  The Agent shall not be required to exercise
any discretion or take any
action, but shall be fully protected in so acting or in
refraining from acting, upon the instructions
of the Majority Banks (except as otherwise provided in Paragraph
10.3, for matters which
require the consent of all Banks), and such instructions shall be
binding upon all Banks and
holders of the Notes, and the Agent shall not be liable to any
party hereto for any consequence
of any such action or refraining from action.  Notwithstanding
any instructions of the Majority
Banks, the Agent shall not be required to take any action that
exposes the Agent to personal
liability or that is contrary to any loan document or applicable
law.

          9.2  Standard of Care.  Neither the Agent nor any of
its officers, directors,
agents, employees or representatives shall be liable for any
action taken or omitted to be taken
by it or any of them under or in connection with this Agreement,
except for its or their own
gross negligence or willful misconduct.  Without limitation of
the generality of the foregoing,
the Agent: (a) may treat the payee of any Notes as the holder
thereof and as a Bank hereunder
until the Agent receives written notice of the assignment or
transfer thereof signed by such payee
and in form satisfactory to the Agent (which notice shall be
binding on all parties hereto); (b)
may consult with legal counsel, independent public accountants
and other experts and advisors
selected by it and shall not be liable for any action taken or
omitted to be taken in good faith
by it in accordance with the advice of such counsel, accountants,
experts or other advisors; (c)
makes no warranty or representation to any Bank and shall not be
responsible to any Bank for
any statements, warranties or representations made in or in
connection with this Agreement or
for any failure or delay in performance by the Borrower or any
Bank under this Agreement;
(d) shall not have any duty to ascertain or to inquire as to the
performance or observance of any
of the terms, covenants or conditions of this Agreement; (e)
shall not be responsible to any Bank
for the due execution, legality, validity, enforceability,
perfection, collectability, genuineness,
sufficiency or value of this Agreement, the Notes, or any other
instrument or document
furnished pursuant thereto or for the accuracy or completeness of
any credit or other information
provided to the Banks; (f) shall incur no liability under or in
respect of this Agreement by acting
upon any notice, consent, certificate or other instrument or
writing (which may be by telecopier,
telegram, cable or telex) believed by it to be genuine and signed
or sent by the proper party or
parties; and (g) shall incur no liability for relying upon any
matters of fact that might reasonably
be expected to be within the knowledge of the Borrower, upon a
certificate or other writing
signed by Borrower, or upon telephone communications with
Borrower which are reasonably
believed to be true and valid.

          9.3  No Waiver of Rights.  With respect to the Notes,
the Agent shall have the
same rights and powers hereunder as any other Bank and may
exercise the same as though it
were not the Agent, and the Agent may accept deposits from, and
generally engage in any kind
of business with, the Borrower.

          9.4  Payments.  The Agent shall use its best efforts to
deliver to each Bank on
the same day as received by Agent in immediately available funds
such Bank's pro rata share
of all payments received by the Agent for the benefit of the
Banks, but in the event Agent is
unable to deliver such payments to any Bank on the same day of
receipt, Agent agrees to pay
such Bank interest on the payment for each day the Agent is
unable to deliver the payments after
the date of its receipt based on the overnight federal funds rate
of interest.  Any payment due
for any reason under this Agreement that is required to be made
on a date on which the Agent
is not open for business shall be extended until the next day on
which the Agent is open for the
transaction of business.

          9.5  Indemnification.  The Agent shall not be required
to do any act hereunder
or under any other document or instrument delivered hereunder or
in connection herewith or
take any action toward the execution or enforcement of the agency
hereby created, or to
prosecute or defend any suit in respect of this Agreement or the
Notes or to advance funds
hereunder upon the failure by any Bank to fund its pro rata share
of the Commitment hereunder,
unless ratably indemnified to its satisfaction (to the extent not
reimbursed by Borrower) by the
holders of the Notes against loss, cost, liability and expense
(including reasonable fees and
out-of-pocket expenses of counsel), claim, demand, action, loss
or liability (except such as result
from Agent's gross negligence or willful misconduct) that Agent
may suffer or incur in
connection with this Agreement or any action taken or omitted by
Agent hereunder.  If any
indemnity furnished to the Agent for or against any loss, cost,
liability, and expense or for any
purpose shall, in the opinion of the Agent, be insufficient or
become impaired, the Agent may
call for additional indemnity and not commence or cease to do the
acts indemnified against until
such additional indemnity is furnished.  Each Bank agrees to
reimburse the Agent promptly upon
demand for such Bank's pro rata share of any expenses referred to
in Paragraph 10.4 incurred
by the Agent to the extent that the Agent is not reimbursed for
such expenses by the Borrower.

          9.6  Exculpation.  Neither Agent nor any of its
directors, officers, employees
or agents shall be liable for any action taken or not taken by it
in connection herewith (a) with
the consent or at the request of the Banks or Majority Banks, as
appropriate, or (b) in the
absence of its own gross negligence or willful misconduct.
Neither Agent nor any of its
directors, officers, employees or agents shall (i) be responsible
for any recitals, representations
or warranties contained in, or for the execution, validity,
genuineness, effectiveness or
enforceability of this Agreement, any Note or any other
instrument or document delivered
hereunder or in connection herewith, or (ii) be under any duty to
inquire into or pass upon any
of the foregoing matters, or to make any inquiry concerning the
performance by Borrower or
any other obligor of its obligations.

          9.7  Credit Investigation.  Each Bank acknowledges that
it has made such
inquiries and taken such care on its own behalf as would have
been the case had the
Commitment been granted and the Loan made directly by such Bank
to the Borrower.  Each
Bank agrees and acknowledges that the Agent makes no
representations or warranties about the
creditworthiness of the Borrower or any other party to this
Agreement or with respect to the
legality, validity, sufficiency or enforceability of this
Agreement, the Notes or the value of any
security therefor and that each Bank has not entered into this
Agreement in reliance upon any
action, statement, representation, or warranty of any other Bank
or Agent.  Each Bank agrees
that it will, independently and without reliance upon the Agent
or any other Bank and based on
such documents and information as it shall deem appropriate at
the time, continue to make its
own credit decisions in taking or not taking action under this
Agreement.  Neither the Agent nor
any other Bank shall have any obligation whatsoever to make any
such credit analysis or
decisions for a Bank or to provide any credit or other
information with respect to the Borrower
now or in the future in the possession of the Agent or such other
Bank, except that the Agent
shall promptly forward to the Banks a copy of any notice received
by the Agent from the
Borrower of the occurrence of an Event of Default hereunder and
copies of all material
documents delivered to it by the Borrower pursuant to the terms
hereof.

          9.8  Resignation.  The Agent may resign at any time as
the Agent under this
Agreement by giving written notice thereof to the Banks and the
Borrower, which resignation
shall be effective upon a successor Agent's acceptance of its
appointment.  Upon any such
resignation, the Majority Banks shall have the right to appoint a
successor Agent hereunder.  If
no such successor Agent shall have been so appointed by the
Majority Banks, or Borrower shall
have reasonably rejected such appointment, within thirty (30)
days after the retiring Agent's
giving of notice of resignation, then the retiring Agent may, on
behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized under
the laws of the United
States of America or of any State thereof having assets of at
least One Billion and No/100
Dollars ($1,000,000,000.00) and which shall be reasonably
acceptable to the Borrower.  Upon
the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor
Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and
duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and
obligations hereunder.  After any retiring Agent's resignation as
an Agent hereunder, the
provisions of this Section IX shall inure to its benefit as to
any actions taken or omitted to be
taken by it while it was an Agent under the Loan Documents.

          9.9  Proration of Payments.  Except as may be provided
in other sections of
this Agreement, including Paragraphs 2.13(B) and 7.2, all other
funds received by Banks, or any
of them, with the exception of funds received by Chemical Bank
with respect to the Letter of
Credit Reimbursement Agreement; shall be allocated pro rata among
all Banks in proportion to
their respective outstanding Loan balances and unreimbursed
Letter of Credit drawings, if any;
provided, following the occurrence of an Event of Default
hereunder and the acceleration of the
Obligations, all funds received by the Banks thereafter shall,
unless the Banks otherwise agree,
be allocated in proportion to their respective outstanding Loan
balances and the Letter of Credit
Liabilities.  If any Bank or other holder of any Notes shall
obtain any payment or other recovery
(whether voluntary, involuntary, by application of offset or
otherwise) on account of principal
of or interest on the Note then held by it in excess of its pro
rata share of payments and other
recoveries obtained by all Banks or other holders on account of
principal of and interest on the
Notes then held by them, such Bank or other holder shall purchase
from the other Banks or
holders such participation in the Notes held by them as shall be
necessary to cause such
purchasing Bank or other holder to share the excess payment or
other recovery ratably with each
of them; provided, however, if all or any portion of the excess
payment or other recovery is
thereafter recovered from such purchasing holder, the purchase
shall be rescinded and the
purchase price restored to the extent of such recovery, but
without interest.  Notwithstanding
the foregoing, no Bank shall have any obligation to account for
or share any amount, property
or profit of any kind received by it for its own account arising
out of a banking or other
relationship with the Borrower apart from the obligations under
the Loan Documents.

          9.10 No Liability For Errors.  The Agent shall not be
liable for any error in
computing the amounts payable to any Bank in respect of any
amounts due to the Banks
hereunder or in making payment of such amounts.  In the event of
an error in computing any
amount payable to any Bank or in the making of a payment, the
Agent, the Borrower and such
Bank shall, forthwith upon discovery of such error, make such
adjustment as shall be required
to correct such error, including the payment of interest on any
amounts that were incorrectly
paid or not paid from the date paid or of the date due to the
date returned or paid, all as the case
may be, at the average daily rate for the overnight sale of
federal funds by the Agent in effect
for such period.

          9.11 Offset.  In addition to and not in limitation of
all rights of offset that any
Bank or other holder of any Note may have under applicable Laws,
each Bank or other holder
of a Note shall, upon the occurrence of any Event of Default
described in this Agreement or in
the Note in question, have the right to appropriate and apply to
the payment of such Notes any
and all balances, credits, deposits, accounts or moneys of the
Borrower then or thereafter with
such Bank or other holder; provided, however, all funds received
as a result of such offsets shall
be applied pro rata among the Banks in proportion to the Letter
of Credit Liabilities and the
respective outstanding Loan amounts.  Each Bank agrees to notify
the Borrower and other Banks
immediately after the exercise by it of this right of offset.


                    SECTION X.  MISCELLANEOUS

          10.1 Construction.  The provisions of this Agreement
shall be in addition to
those of any guaranty, pledge or security agreement, note or
other evidence of liability held by
the Banks, all of which shall be construed as complementary to
each other; provided, in the
event of any inconsistency, the provisions of this Agreement
shall control.  Nothing herein
contained shall prevent the Banks from enforcing any or all other
notes, guaranties, pledge or
security agreements in accordance with their respective terms.

          10.2 Further Assurance.  From time to time, the
Borrower will execute and
deliver to the Banks such additional documents and will provide
such additional information as
the Banks may reasonably require to carry out the terms of this
Agreement and be informed of
the Borrower's operations, business and condition.

          10.3 Enforcement and Waiver by the Banks.  The Majority
Banks shall have
the sole and exclusive right to administer, amend, or modify the
Loan Documents, and are
hereby empowered to act for the Banks with regard to the
aggregate Commitments and the
documentation thereof as if said Majority Banks were the sole
lenders or extenders of credit
under the Loan Documents; provided, however, that it shall take
an affirmative vote of all Banks
to:  (i) increase any of the several Commitments; (ii) decrease
any of the interest rates on the
Loans; (iii) extend any Commitment Termination Date or Loan
Termination Date on the
Revolving Loan or the Capital Expenditure Loan; (iv) reduce or
postpone the principal payments
due on any Term Loans; (v) postpone any payments of interest or
interest payment dates; (vi)
release any collateral; (vii) amend the definition of Majority
Banks; and (viii) amend this
Paragraph 10.3; and provided further, that with respect to the
Working Capital Loan,
NationsBank of Tennessee, N.A. shall have the sole right without
consulting any other Bank to
determine whether to extend from time to time the Working Capital
Loan Termination Date.
The Banks shall have the right at all times to enforce the
provisions of the Loan Documents in
strict accordance with the terms thereof, notwithstanding any
conduct or custom on the part of
the Banks and/or Agent in refraining from so doing at any time or
times.  The failure of the
Banks at any time or times to enforce their rights under such
provisions, strictly in accordance
with the same, shall not be construed as having created a custom
in any way or manner contrary
to specific provisions of the Loan Documents or as having in any
way or manner modified or
waived the same.  All rights and remedies of the Banks are
cumulative and concurrent and the
exercise of one right or remedy shall not be deemed a waiver or
release of any other right or
remedy.

          10.4 Expenses of the Banks.  The Borrower will, on
demand, reimburse the
Agent and the Banks for all out-of-pocket expenses, including the
reasonable fees and expenses
of legal counsel for the Agent and the Banks, incurred by the
Agent and the Banks in connection
with the preparation, administration, amendment, modification, or
enforcement of the Loan
Documents and the collection or attempted collection of the
Notes.

          10.5 Notices.  Any notices or consents required or
permitted by this Agreement
shall be in writing and shall be deemed delivered when delivered
in person, or when sent by
certified mail, postage prepaid, return receipt requested, by
overnight courier service, or by

any time held by the
Banks on which the Borrower or any Participating Subsidiary is in
any way liable; and (2) notice

provided in Paragraph 8.2, before

Borrower or any Participating
Subsidiary, and, except where required hereby or by any
applicable Laws, notice of any other
action taken by the Banks; and

               (B)  Release the Banks and their officers,
directors, attorneys,
employees, and agents from all claims for loss or damage caused
by any act or omission on the
part of any of them except for gross negligence, recklessness or
willful misconduct.

          10.7 Indemnification.  Borrower and each Participating
Subsidiary hereby
indemnify and hold the Banks and their officers, directors,
attorneys, employees and agents free
and harmless from and against any and all actions, causes of
action, suits, losses, liabilities and
damages, and expenses in connection therewith, including without
limitation counsel fees and
disbursements, incurred by the Banks or any of them as a result
of, or arising out of, or relating
to the execution, delivery, performance or enforcement of the
Loan Documents or any
instrument  contemplated therein, except for any Bank's gross
negligence or willful misconduct.
If and to the extent that the foregoing undertaking may be
unenforceable for any reason,
Borrower and each Participating Subsidiary hereby agree to make
the maximum contribution to
the payment and satisfaction of such liabilities and costs
permitted under applicable Laws.

          10.8 Participations and Assignments.  Notwithstanding
any other provision of
this Agreement, the Borrower understands that any Bank may at any
time enter into participation
agreements with one or more participating banks whereby such Bank
will allocate certain
percentages of its Commitment to such bank or banks.  The
Borrower acknowledges that, for
the convenience of all parties, this Agreement is being entered
into with the Banks only and that
Borrower's obligations hereunder are undertaken for the benefit
of, and as an inducement to, any
such participating bank as well as the Banks.  In addition, any
Bank may assign to one or more
lenders all or a portion of its rights and obligations as a Bank
under this Agreement and the
other Loan Documents; provided, however, that prior thereto any
assigning Bank must obtain
the written consent of the Agent and the Borrower to the
assignee, which consent shall not be
unreasonably withheld if being made to an Eligible Assignee.

          10.9 Applicable Laws.  The Laws of the State of
Tennessee shall govern the
construction of this Agreement and the rights and remedies of the
parties hereto.

          10.10Binding Effect, Assignment and Entire Agreement.
This Agreement shall
inure to the benefit of, and shall be binding upon, the
respective successors and permitted
assigns of the parties hereto.  The Borrower has no right to
assign any of its rights or obligations
hereunder without the prior written consent of the Banks.  This
Agreement and the documents
executed and delivered pursuant hereto constitute the entire
agreement between the parties, and
supersede all prior agreements and understandings among the
parties hereto.  This Agreement
may be amended only by a writing signed on behalf of each party.

          10.11Severability.  If any provision of this Agreement
shall be held invalid
under any applicable Laws, such invalidity shall  not affect any
other provision of this
Agreement that can be given effect without the invalid provision,
and, to this end, the provisions
hereof are severable.

          10.12Counterparts.  This Agreement may be executed by
the parties
independently in any number of counterparts, all of which
together shall constitute but one and
the same instrument which is valid and effective as if all
parties had executed the same
counterpart.

          10.13Venue.  It is agreed that venue for any action
arising in connection with
this Agreement or the Obligations secured hereby shall lie
exclusively with courts sitting in the
states of Tennessee and New York, unless the Banks and Agent
otherwise agree in writing.

          10.14Confidentiality.  Agent and the Banks, together
with their employees,
agents or representatives who have a reasonable need to know such
information, agree to treat
confidentially all information concerning Zemex Corporation and
its Subsidiaries or their assets
and operations obtained by Agent or the Banks or by any of
Agent's or the Banks' authorized
agents or representatives, which information is not (i) contained
in a report or other document
filed with a securities commission or regulatory authority, (ii)
distributed by Zemex Corporation
to its shareholders or (iii) otherwise available to the public
generally (other than by Agent's or
Banks' breach of these confidentiality obligations); provided,
however, that the foregoing
confidentiality restrictions shall not apply where Agent or the
Banks are required to disclose such
information due to a valid subpoena or court order or other
external bank regulatory reporting
requirements.  These confidentiality obligations shall survive
the term of this Agreement by two
years.

          10.15Waiver of Jury Trial.  EACH PARTY HERETO,
INCLUDING THE
BORROWER, EACH SUBSIDIARY, THE BANKS, AND THE AGENT, HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE (TO THE EXTENT
PERMITTED BY APPLICABLE LAWS) ANY RIGHTS THEY MAY HAVE TO A TRIAL
BY JURY OF ANY DISPUTE ARISING UNDER, RELATING TO, OR CONNECTED
WITH
