         or decreased, as the case may be, by an amount equal to any increase
         or decrease in the Base Rate, with such adjustments to be effective as

therein.

SECTION 2.    CREDIT FACILITY

       2.1.   Revolving Credit Loans.  Subject to the terms and conditions of
this Agreement, Lender agrees to make Revolving Credit Loans to Borrower from
time to time, in amounts determined by Lender in its sole discretion, up to a
maximum principal amount at any time outstanding equal to the Borrowing Base at
such time.  If the unpaid balance of the Revolving Credit Loans should exceed
the Borrowing Base or any other limitation set forth in this Agreement, such
Revolving Credit Loans shall nevertheless constitute Obligations that are
secured by the Collateral and entitled to all benefits thereof.  Insofar as
Borrower may request and Lender may be willing in its sole and absolute
discretion to make Revolving Credit Loans to Borrower at a time when the unpaid
balance of Revolving Credit Loans exceeds, or would exceed with the making of
any such Revolving Credit Loan, the Borrowing Base (any such Loan or Loans
being herein referred to individually as an "Overadvance" and collectively as





LOAN AND SECURITY AGREEMENT - Page 15
<PAGE>   16
"Overadvances"), Lender shall enter such Overadvances as debits in the Loan
Account.  All Overadvances shall be payable ON DEMAND, shall be secured by the
Collateral and shall bear interest as provided herein for Revolving Credit
Loans generally.  The Revolving Credit Loans shall be used solely for the
satisfaction of existing Indebtedness of Borrower to and for Borrower's general
operating capital needs to the extent not inconsistent with the provisions of
this Agreement.

       A request for a Revolving Credit Loan shall be made or shall be deemed
to be made, in the following manner:  (i) Borrower may give Lender notice of
its intention to borrow, in which notice Borrower shall specify the amount of
the proposed borrowing and the proposed borrowing date (which notice shall be
in the form of a Eurodollar Borrowing Notice pursuant to Section 3.7(A) hereof
if Borrower intends to borrow a Eurodollar Loan); (ii) the becoming due of any
amount required to be paid under this Agreement, under the Term Note or under
any of the other Loan Documents as interest shall be deemed irrevocably to be a
request for a Revolving Credit Loan on the due date in the amount required to
pay such interest; (iii) the becoming due of any amount required to be paid
under this Agreement, under the term Note or under any of the other Loan
Documents as principal shall be deemed irrevocably to be a request for a
Revolving Credit Loan on the due date for the amount required to pay such
principal; (iv) any payment made by Lender pursuant to a Letter of Credit or LC
Guaranty which is not immediately reimbursed by Borrower shall be deemed
irrevocably to be a request for a Revolving Credit Loan on the date of such
payment by Lender; and (v) the becoming due of any other Obligations shall be
deemed irrevocably to be a request for a Revolving Credit Loan on the due date
in the amount then so due.

       2.2.   Term Loan.  Subject to the terms and conditions of this
Agreement, Lender agrees to make a term loan (the "Term Loan") to Borrower on
the Closing Date in the principal amount of $500,000.  The Term Loan shall be
repayable in accordance with the terms of the Term Note and shall be secured by
all of the Collateral.  The proceeds of the Term Loan shall be used solely to
pay off in full all existing Indebtedness which is presently secured by a Lien
against the Lufkin Real Property, with any proceeds remaining after paying in
full such Indebtedness to be used for purposes for which the proceeds of the
Revolving Credit Loans are authorized to be used.  Borrower may not reborrow
any amount repaid with respect to the Term Loan.  If Borrower sells any of the
Equipment or real Property, or if any of the Collateral is lost or destroyed or
is taken by condemnation, Borrower shall pay to Lender, unless otherwise agreed
to by Lender, as and when received by Borrower and as a mandatory prepayment of
the Term Loan (or, at Lender's option, such of the other Obligations as Lender
shall elect), a sum equal to the net proceeds (including insurance payments)
received by Borrower from such sale, loss, destruction or condemnation.
Notwithstanding any other provision of this Agreement or any of the other Loan
Documents, and without affecting in any manner the rights of Lender under the
other Sections of this Agreement (including, without limitation, Sections 10.1
and 10.2), it is understood and agreed that Lender will not make the Term Loan
unless and until each of the following additional conditions has been and
continues to be satisfied, all in form and substance satisfactory to Lender and
its counsel:

              (A)    Borrower shall have executed and delivered to Lender the
Term Note;





LOAN AND SECURITY AGREEMENT - Page 16
<PAGE>   17
              (B)    Borrower shall have executed and delivered to Lender the
Lufkin Mortgage, which Lufkin Mortgage shall have been recorded with the
appropriate filing officers;

              (C)    Borrower shall have delivered to Lender, at Borrower's
expense, a mortgagee title insurance policy (or commitment to issue a mortgagee
title insurance policy, provided Borrower simultaneously pays all premiums and
satisfies all conditions necessary for issuance of such policy) covering the
Lufkin Real Property issued by a title insurance company satisfactory to Lender
insuring Lender as mortgagee; such policy shall be in form and substance
satisfactory to Lender and shall insure a valid first Lien in favor of Lender
on the Lufkin Real Property, subject only to those exceptions acceptable to
Lender and its counsel;

              (D)    Borrower shall have delivered to Lender such other
documents, including, without limitation, surveys of the Lufkin  Real Property,
certificates of corporate resolutions and incumbency of officers, opinions of
counsel, and other documents and instruments as Lender and its counsel may
reasonably request relating to the Lufkin Real Property, the Term Note and the
Lufkin Mortgage;

              (E)    If requested by Lender, Lender shall have received a
current, fair market appraisal of the Lufkin Real Property, prepared by an
appraiser satisfactory to Lender, in its sole discretion, in an amount and in
form and substance satisfactory to Lender, in its sole discretion;

              (F)    Lender shall have received a current, complete Phase I
environmental site assessment regarding the Lufkin Real Property, performed by
a qualified environmental engineer or specialist acceptable to Lender, in its
sole discretion, such environmental site assessment to be in form and substance
satisfactory to Lender, in its sole discretion, together with such other
satisfactory environmental studies, reports, and reviews as shall be required
by Lender, in its sole discretion; and

              (G)    The Term Loan Closing Date must occur August 31, 1997.

       2.3.   All Loans to Constitute One Obligation.  All Loans shall
constitute one general obligation of Borrower, and shall be secured by Lender's
security interest in and Lien upon all of the Collateral, and by all other
security interests and Liens heretofore, now or at any time or times hereafter
granted by Borrower to Lender.

       2.4.   Loan Account.  Lender shall enter all Loans as debits to the Loan
Account and shall also record in the Loan Account all payments made by Borrower
on any Obligations and all proceeds of Collateral which are finally paid to
Lender, and may record therein, in accordance with customary accounting
practice, all charges and expenses properly chargeable to Borrower and any
other Obligation.

       2.5    Reimbursement Obligations.  If Lender shall pay any amount under
a Letter of Credit or LC Guaranty, then Borrower shall automatically become
obligated to immediately reimburse such amount to Lender, together with
interest from and after the date Lender makes





LOAN AND SECURITY AGREEMENT - Page 17
<PAGE>   18
such payment under such Letter of Credit or LC Guaranty until payment in full
to Lender by Borrower of Borrower's reimbursement obligation which shall accrue
at the applicable per annum rate of interest then applicable for Revolving
Credit Loans.

SECTION 3.    INTEREST, FEES, TERM AND REPAYMENT

       3.1.   Interest and Charges.

              (A)    Interest shall accrue on the principal amount of the Term
Loan in accordance with the terms of the Term Note, and the principal amount of
the Revolving Credit Loans outstanding at the end of each day shall bear
interest at the following rates per annum (individually called, as applicable,
an "Applicable Annual Rate"):  (i) Eurodollar Loans shall bear interest at a
rate per annum equal to 2.00% above the Eurodollar Base Rate for the Eurodollar
Interest Period applicable thereto and (ii) all other Revolving Credit Loans
shall bear interest at a rate per annum equal to .50% above the Base Rate.
Revolving Credit Loans shall bear interest at a rate per annum equal to .50%
above the Base Rate unless the Borrower provides a Eurodollar Borrowing Notice
to the Lender in accordance with Section 3.7(A) irrevocably electing that all
or a portion of the Revolving Credit Loans are to bear interest at a Eurodollar
Base Rate.  Each Revolving Credit Loan that is not a Eurodollar Loan shall be
increased or decreased, as the case may be, by an amount equal to any increase
or decrease in the Base Rate, with such adjustments to be effective as of the
opening of business on the day that any such change in the Base Rate becomes
effective.  The Base Rate in effect on the date hereof shall be the Base Rate
effective as of the opening of business on the date hereof, but if this
Agreement is executed on a day that is not a Business Day, the Base Rate in
effect on the date hereof shall be the Base Rate effective as of the opening of
business on the last Business Day immediately preceding the date hereof.
Interest shall be calculated on a daily basis (computed on the actual number of
days elapsed over a year of 360 days), commencing on the date hereof, and shall
be payable monthly, in arrears, on the first day of each month; provided,
however, that interest at the Maximum Legal Rate shall be computed on the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be.  Upon and after the occurrence of an Event of Default, and during the
continuation thereof, the principal amount of the Obligations shall bear
interest at the lesser of (i) the Maximum Legal Rate or (ii) a fluctuating rate
per annum, calculated daily (computed on the actual days elapsed over a year of
360 days), equal to 4.0% above the Applicable Annual Rate or other applicable
rate of interest (the "Default Rate").

              (B)    Notwithstanding the foregoing or any other provision in
this Agreement, (i) if at any time the amount of interest computed on the basis
of the Applicable Annual Rate or the Default Rate would exceed the amount of
such interest computed upon the basis of the maximum rate of interest permitted
by applicable state or federal law in effect from time to time hereafter (the
"Maximum Legal Rate"), the interest payable under this Agreement shall be
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Applicable Annual Rate or Default Rate, as applicable, shall not reduce
such interest thereafter payable hereunder below the amount computed on the
basis of the Maximum Legal Rate until the aggregate amount of such interest
accrued and payable under this Agreement equals the total amount of interest
which would have accrued if such interest had been at all times computed





LOAN AND SECURITY AGREEMENT - Page 18
<PAGE>   19
solely on the basis of the Applicable Annual Rate or Default Rate, as
applicable; and (ii) unless preempted by federal law, the Applicable Annual
Rate or Default Rate, as applicable, from time to time in effect hereunder may
not exceed the "indicated ceiling rate" from time to time in effect under Tex.
Rev. Civ. Stat. Ann. art 5069-1.04(c) (Vernon 1987).

              (C)    No agreements, conditions, provisions or stipulations
contained in this Agreement or any other instrument, document or agreement
between Borrower and Lender or default of Borrower, or the exercise by Lender
of the right to accelerate the payment of the maturity of principal and
interest, or to exercise any option whatsoever contained in this Agreement or
any other agreement between Borrower and Lender, or the arising of any
contingency whatsoever, shall entitle Lender to contract for, charge, or
receive, in any event, interest exceeding the Maximum Legal Rate.  In no event
shall Borrower be obligated to pay interest exceeding such Maximum Legal Rate
and all agreements, conditions or stipulations, if any, which may in any event
or contingency whatsoever operate to bind, obligate or compel Borrower to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is contracted
for, charged or received in excess of the Maximum Legal Rate ("Excess"),
Borrower acknowledges and stipulates that any such contract, charge, or receipt
shall be the result of an accident and bona fide error, and that any Excess
received by Lender shall be applied, first, to reduce the principal then unpaid
hereunder; second, to reduce the other Obligations; and third, returned to
Borrower, it being the intention of the parties hereto not to enter at any time
into a usurious or otherwise illegal relationship.  Borrower recognizes that,
with fluctuations in the Base Rate, the Eurodollar Base Rate and the Maximum
Legal Rate, such a result could inadvertently occur.  By the execution of this
Agreement, Borrower covenants that (i) the credit or return of any Excess shall
constitute the acceptance by Borrower of such Excess, and (ii) Borrower shall
not seek or pursue any other remedy, legal or equitable, against Lender, based
in whole or in part upon contracting for, charging or receiving of any interest
in excess of the maximum authorized by applicable law.  For the purpose of
determining whether or not any Excess has been contracted for, charged or
received by Lender, all interest at any time contracted for, charged or
received by Lender in connection with this Agreement shall be amortized,
prorated, allocated and spread in equal parts during the entire term of this
Agreement.

              (D)    The provisions of Section 3.1(C) shall be deemed to be
incorporated into every document or communication relating to the Obligations
which sets forth or prescribes any account, right or claim or alleged account,
right or claim of Lender with respect to Borrower (or any other obligor in
respect of Obligations), whether or not any provision of Section 3.1 is
referred to therein.  All such documents and communications and all figures set
forth therein shall, for the sole purpose of computing the extent of the
Obligations and obligations of the Borrower (or other obligor) asserted by
Lender thereunder, be automatically recomputed by Borrower or obligor, and by
any court considering the same, to give effect to the adjustments or credits
required by Section 3.1(C).

              (E)    If the applicable state or federal law is amended in the
future to allow a greater rate of interest to be charged under this Agreement
or the Other Agreements than is





LOAN AND SECURITY AGREEMENT - Page 19
<PAGE>   20
presently allowed by applicable state or federal law, then the limitation of
interest hereunder shall be increased to the maximum rate of interest allowed
by applicable state or federal law as amended, which increase shall be
effective hereunder on the effective date of such amendment, and all interest
charges owing to Lender by reason thereof shall be payable upon demand.

              (F)    For the purpose of computing interest hereunder, all items
of payment received by Lender shall be deemed applied by Lender on account of
the Obligations (subject to final payment of such items) one (1) Business Day
after receipt by Lender of such items in Lender's account located in Chicago,
Illinois, and Lender shall be deemed to have received such items of payment on
the date specified in Section 3.5 hereof.

       3.2.   Unused Facility Fee.  From the date hereof, Borrower agrees to
pay to Lender a quarterly unused facility fee, equal to one-quarter percent
(0.25%) per annum of the average daily unused portion of the Commitment,
payable quarterly in arrears, the first payment being due on July l, 1997 and
continuing on the first day of each July, October, January and April thereafter
during the term of this Agreement and upon the termination hereof.

       3.3.   Term of Agreement; Termination.

              (A)    Subject to Lender's right to cease making Loans to
Borrower at any time upon or after the occurrence of a Default or an Event of
Default, the provisions of this Agreement shall be in effect for a period from
the date hereof, through and including January 2, 1999 (the "Original Term").
Upon written request by Borrower, Lender may, in its sole and absolute
discretion, renew this Agreement for any number of successive one year periods
thereafter (a "Renewal Term"), but Lender shall have no obligation to do so.

              (B)    Upon at least 90 days prior written notice to Lender,
Borrower may, at its option, terminate this Agreement; provided, however, no
such termination shall be effective until Borrower has paid all of the
Obligations in immediately available funds.  It is understood that Borrower may
elect to terminate this Agreement in its entirety only; no section or lending
facility may be terminated singly.

              (C)    In addition to and not in limitation of any other
provision of this Agreement, the parties hereto agree that this Agreement shall
also be deemed terminated upon the effective date of the termination of the
Sepco Loan Agreement.

              (D)    At the effective date of any termination of this
Agreement, Borrower shall pay to Lender (in addition to the then outstanding
principal, accrued interest and other charges owing under this Agreement and
any of the Other Agreements), as liquidated damages for the loss of the bargain
and not as a penalty, an amount equal to 0.5% of the highest of the Average
Monthly Loan Balances outstanding pursuant to Section 2.1 during the twelve
month period ending on the date of termination if termination occurs at any
time prior to January 2, 1999 or during any Renewal Term thereafter.  If
termination occurs on the last day of the Original Term or the last day of any
Renewal Term, no termination charge shall be payable.





LOAN AND SECURITY AGREEMENT - Page 20
<PAGE>   21
              (E)    All of the Obligations shall be forthwith due and payable
upon any termination of this Agreement.  Except as otherwise expressly provided
in this Agreement or any of the Other Agreements, no termination or
cancellation (regardless of cause or procedure) of this Agreement or any of the
Other Agreements shall in any way affect or impair the rights, powers or
privileges of Lender or the obligations or liabilities of Borrower in any way
relating to (i) any transaction or event occurring prior to such termination or
cancellation or (ii) any of the undertakings, agreements, covenants, warranties
or representations of Borrower contained in this Agreement or any of the Other
Agreements.  All such undertakings, agreements, covenants, warranties and
representations of Borrower shall survive such termination or cancellation,
and, notwithstanding such termination or cancellation, Lender shall retain its
Liens in the Collateral and all of its rights and remedies under this Agreement
and the Other Agreements until Borrower has paid the Obligations to Lender, in
full, in immediately available funds.

       3.4.   Payments.  Principal and interest on the Term Loan shall be
payable as provided in the Term Note.  Except where evidenced by notes or other
instruments issued or made by Borrower to Lender specifically containing
payment provisions which are in conflict with this Section 3.4 (in which event
the conflicting provisions of said notes or other instruments shall govern and
control), the Obligations shall be payable as follows:

              (A)    Principal payable on account of Revolving Credit Loans
made by Lender to Borrower, shall be payable by Borrower to Lender immediately
upon the earliest of (i) the receipt by Lender or Borrower of any proceeds of
any of the Collateral, to the extent of said proceeds, (ii) the occurrence of
an Event of Default in consequence of which Lender elects to accelerate the
maturity and payment of the Obligations, or (iii) termination of this
Agreement; provided, however, that if the principal balance of Revolving Credit
Loans outstanding at any time shall exceed the Borrowing Base at such time,
Borrower shall, on demand, repay the Revolving Credit Loans in an amount
sufficient to reduce the aggregate unpaid principal amount of such Revolving
Credit Loans by an amount equal to such excess.

              (B)    Interest accrued on the Obligations shall be due on the
earliest of (i) the first day of each month (for the immediately preceding
month), computed through the last calendar day of the preceding month, (ii) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the Obligations, or (iii) termination of
this Agreement; provided, however, that Borrower hereby irrevocably authorizes
Lender, in Lender's sole discretion, to advance to Borrower, and to charge to
the Loan Account hereunder as a Revolving Credit Loan, a sum sufficient each
month to pay all interest accrued on the Obligations during the immediately
preceding month, and to pay all costs, fees and expenses at any time owed by
Borrower to Lender hereunder.

              (C)    The balance of the Obligations requiring the payment of
money, if any, shall be payable by Borrower to Lender as and when provided in
this Agreement or the Other Agreements, or on demand, whichever is earlier.

       3.5.   Application of Payments and Collections.  All items of payment
received by Lender by 12:00 noon, Dallas, Texas time, on any Business Day,
shall be deemed received on





LOAN AND SECURITY AGREEMENT - Page 21
<PAGE>   22
that Business Day.  All items of payment received after 12:00 noon, Dallas,
Texas time, on any Business Day, shall be deemed received on the following
Business Day.  Borrower irrevocably waives the right to direct the application
of any and all payments and collections at any time or times hereafter received
by Lender from or on behalf of Borrower, and Borrower does hereby irrevocably
agree that Lender shall have the continuing exclusive right to apply and
reapply any and all such payments and collections received at any time or times
hereafter by Lender or its agent against the Obligations, in such manner as
Lender may deem advisable, notwithstanding any entry by Lender upon any of its
books and records.  If as the result of collections of Accounts as authorized
by Section 5.4 hereof a credit balance exists in the Loan Account, such credit
balance shall not accrue interest in favor of Borrower, but shall be available
to Borrower at any time or times for so long as no Default or Event of Default
exists.  Such credit balance shall not be applied or be deemed to have been
applied as a prepayment of the Term Loan; provided, however, Lender may offset
such credit balance against the Obligations upon or after the occurrence of any
Event of Default.

       3.6.   Statements of Account.  Lender will account to Borrower monthly
with a statement of Loans, charges and payments made pursuant to this
Agreement, and such account rendered by Lender shall be deemed final, binding
and conclusive upon Borrower unless Lender is notified by Borrower in writing
to the contrary within 30 days of the date each account is mailed to Borrower.
Such notice shall only be deemed an objection to those items specifically
objected to therein.

       3.7.   Additional Provisions Regarding Eurodollar Loans.

              (A)    Manner of Borrowing a Eurodollar Loan.  Borrower shall
give Lender notice of its intention to borrow a Eurodollar Loan in the form of
Exhibit A attached hereto (a "Eurodollar Borrowing Notice"), in which notice
Borrower shall specify (x) the aggregate amount of such Eurodollar Loan, (y)
the requested date of such Eurodollar Loan, and (z) the Eurodollar Interest
Period applicable thereto.  Borrower shall give Lender the Eurodollar Borrowing
Notice at least two (2) Business Days prior to the requested date of the
Eurodollar Loan.  With respect to such Eurodollar Loans, (i) each Eurodollar
Loan shall be in an integral multiple of $1,000,000, (ii) no more than four (4)
Eurodollar Interest Periods may be in existence at any one time, and (iii)
Borrower may not request a Eurodollar Loan if there exists a Default or Event
of Default.  The Borrower shall select Eurodollar Interest Periods with respect
to Eurodollar Loans so that no Eurodollar Interest Period expires after the end
of the Original Term, or if extended pursuant to Section 3.3(A), any Renewal
Term.  An outstanding Revolving Credit Loan may be converted to a Eurodollar
Loan at any time subject to the provisions of this Section 3.7.

              (B)    Interest on Eurodollar Loans.  Each Eurodollar Loan shall
bear interest from and including the first day of the Eurodollar Interest
Period applicable thereto (but not including the last day of such Eurodollar
Interest Period) at the interest rate determined as applicable to such
Eurodollar Loan, but interest on such Eurodollar Loan shall be payable as
provided in Section 3.4.  If at the end of a Eurodollar Interest Period for an
outstanding Eurodollar Loan, Borrower has failed to deliver to Lender a new
Eurodollar Borrowing Notice





LOAN AND SECURITY AGREEMENT - Page 22
<PAGE>   23
with respect to such Eurodollar Loan or to pay such Eurodollar Loan, then such
Eurodollar Loan shall be converted to a Revolving Credit Loan bearing interest
at a rate, and subject to all other terms and conditions of this Agreement,
applicable to Revolving Credit Loans not constituting Eurodollar Loans on and
after the last day of such Eurodollar Interest Period until paid or until the
effective date of a new Eurodollar Borrowing Notice with respect thereto.

              (C)    Availability of Eurodollar Loans.  If Lender determines
that maintenance of any of its Eurodollar Loans would violate any applicable
law, rule, regulation or directive, whether or not having the force of law,
Lender shall suspend the availability of Eurodollar Loans and require any
Eurodollar Loans outstanding to be repaid (provided, that, without in any way
impairing Borrower's obligations under Section 3.7(D) and Section 3.7(E), to
the extent that Borrower is entitled to request a Revolving Credit Loan bearing
interest at the Base Rate, Borrower may request such a Revolving Credit Loan in
order to repay the Eurodollar Loans); or if Lender determines that (x) deposits
of a type or maturity appropriate to match fund Eurodollar Loans are not
available or (y) the Eurodollar Base Rate does not accurately reflect the cost
of making a Eurodollar Loan, then Lender shall suspend the availability of
Eurodollar Loans after the date of any such determination.

              (D)    Funding Indemnification. If any payment of a Eurodollar
Loan occurs on a date which is not the last day of the applicable Eurodollar
Interest Period, whether because of acceleration, prepayment or otherwise, or a
Eurodollar Loan is not made on the date specified by Borrower because Borrower
has not satisfied the conditions precedent to such Eurodollar Loan contained in
this Agreement or has otherwise breached the terms of this Agreement, Borrower
will indemnify Lender for any loss or cost incurred by it resulting therefrom,
including without limitation any loss or cost in liquidating or employing
deposits acquired to fund or maintain the Eurodollar Loan.

              (E)    Lender Statements: Survival of Indemnity.  Within sixty
(60) days of the date upon which Lender suspends the availability of Eurodollar
Loans under Section 3.7(C) hereof or learns of any loss or cost for which
Borrower has indemnified Lender under Section 3.7(D) hereof, Lender shall
deliver a written statement as to the amount due under Section 3.7(C) or (D).
Such written statement shall set forth in reasonable detail the calculations
and basis therefor upon which Lender determined such amount and shall be final,
conclusive and binding on Borrower in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though the Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding
to the deposit used as a reference in determining the Eurodollar Base Rate
applicable to such Eurodollar Loan whether in fact that is the case or not.
Unless otherwise provided herein, the amount specified in the written statement
shall be payable on demand after receipt by Borrower of the written statement.

       3.8.   Yield Protection. If either (i) the adoption of any applicable
law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by Lender with any request or directive (whether or not





LOAN AND SECURITY AGREEMENT - Page 23
<PAGE>   24
having the force of law) of any such authority, central bank or comparable
agency shall subject Lender to any tax (including without limitation any United
States interest equalization or similar tax, however named), duty or other
charge with respect to any Eurodollar Loan or Lender's obligation to compute
interest on the principal balance of any Eurodollar Loan at a rate based upon
the Eurodollar Base Rate, or shall change the basis of taxation of payments to
Lender of the principal of or interest on any Eurodollar Loan or any other
amounts due under this Agreement in respect of any Eurodollar Loan or Lender's
obligation to compute the interest on the principal balance of any Eurodollar
Loan at a rate based upon the Eurodollar Base Rate, or (ii) 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), special
deposit or similar requirement against assets of, deposits with or for the
account of, or credit extended by, Lender, or shall impose on Lender (or its
eurodollar lending office) or any relevant interbank eurodollar market any
other condition affecting any Eurodollar Loan or Lender's obligation to compute
the interest on the principal balance of any Eurodollar Loan at a rate based
upon the Eurodollar Base Rate; and the result of any of the foregoing is to
increase the cost to Lender of maintaining any Eurodollar Loans, or to reduce
the amount of any sum received or receivable by Lender under this Agreement by
an amount deemed by Lender to be material, then upon demand by Lender, Borrower
shall pay to Lender such additional amount or amounts as will compensate Lender
for such increased cost or reduction.  Lender will promptly notify Borrower of
any event of which it has knowledge, occurring after the date hereof, which
will entitle Lender to compensation pursuant to this Section 3.8.  A
certificate of Lender claiming compensation under this Section 3.8 and setting
forth the additional amount or amounts to be paid to Lender hereunder shall be
conclusive in the absence of manifest error.

       3.9    Closing Fee.  Borrower agrees to pay to Lender on the date of
execution of this Agreement, a closing fee equal to $50,000, which fee shall be
deemed fully earned and non-refundable as of the date of execution of this
Agreement.

SECTION 4.    COLLATERAL:  GENERAL TERMS

       4.1.   Security Interest in Collateral.  To secure the prompt payment
and performance to Lender of the Obligations, Borrower hereby grants to Lender
a continuing security interest in and Lien upon all of the Property and
interests in Property of Borrower, whether now owned or existing or hereafter
created, acquired or arising and wheresoever located including, without
limitation, the following:

              (A)    Accounts;

              (B)    Inventory;

              (C)    Equipment;

              (D)    General Intangibles;





LOAN AND SECURITY AGREEMENT - Page 24
<PAGE>   25
              (E)    All investment property (as defined in Section 9.115 of
the Code);

              (F)    All real Property;

              (G)    all monies and other Property of any kind, now or at any
time or times hereafter, in the possession or under the control of Lender or a
bailee of Lender;

              (H)    all accessions to, substitutions for and all replacements,
products and cash and non-cash proceeds of (A), (B), (C), (D), (E), (F) and (G)
above, including, without limitation, Proceeds of and unearned premiums with
respect to insurance Policies insuring any of the Collateral; and

              (I)    all books and records (including, without limitation,
customer lists, credit files, computer programs, print-outs, and other computer
materials and records) of Borrower pertaining to any of (A), (B), (C), (D),
(E), (F), (G) or (H) above.

       4.2.   Lien on Realty.  The due and punctual payment and performance of
the Obligations shall also be secured by the Lien created by the Mortgages upon
all real Property of Borrower described therein.  Borrower shall deliver to
Lender, at Borrower's expense, mortgagee title insurance policies issued by a
title insurance company satisfactory to Lender insuring Lender as mortgagee;
such policies shall be in form and substance satisfactory to Lender and shall
insure a valid first Lien in favor of Lender on the Property covered thereby,
subject only to those exceptions acceptable to Lender and its counsel.
Borrower shall deliver to Lender such other documents, including, without
limitation, as-built survey prints of the real Property, as Lender and its
counsel may reasonably request relating to the real Property subject to the
Mortgage.

       4.3.   Lien Perfection.  Borrower agrees to execute the UCC-l financing
statements provided for by the Code or otherwise together with any and all
other instruments, assignments or documents and shall take such other action as
may be reasonably required to perfect or to continue the perfection of Lender's
security interest in the Collateral as a first priority Lien subject to
Permitted Liens only.  Unless prohibited by applicable law, Borrower hereby
authorizes Lender to execute and file any such financing statement on
Borrower's behalf.  The parties agree that a carbon, Photographic or other
reproduction of this Agreement shall be sufficient as a financing statement and
may be filed in any appropriate office in lieu thereof.

       4.4.   Location of Collateral.  All tangible items of Collateral, other
than Inventory in transit, motor vehicles and investment property held in an
account with a securities intermediary, will at all times be kept by Borrower
at one or more of the business locations set forth in Exhibit B and shall not,
without the prior written approval of Lender, be moved therefrom except, prior
to an Event of Default, for sales of Inventory in the ordinary course of
business and dispositions of Equipment that are authorized by Section 7.2
hereof.

       4.5.   Insurance of Collateral.  Borrower agrees to maintain and pay for
insurance upon all Collateral wherever located, in storage or in transit in
vehicles, including goods evidenced by





LOAN AND SECURITY AGREEMENT - Page 25
<PAGE>   26
documents, covering casualty, hazard, public liability and such other risks and
in such amounts and with such insurance companies as shall be reasonably
satisfactory to Lender to insure Lender's interest in the Collateral.  Borrower
shall deliver the originals of such policies to Lender with satisfactory
endorsements naming Lender as loss payee and as mortgagee pursuant to a
standard mortgagee clause.  Each policy of insurance or endorsement shall
contain a clause requiring the insurer to give not less than 30 days prior
written notice to Lender in the event of cancellation of the policy for any
reason whatsoever and a clause that the interest of Lender shall not be
impaired or invalidated by any act or neglect of Borrower or owner of the
Property nor by the occupation of the premises for purposes more hazardous than
are permitted by said policy.  If Borrower fails to provide and pay for such
insurance, Lender may, at Borrower's expense, procure the same, but shall not
be required to do so.  Borrower agrees to deliver to Lender, promptly as
rendered, true copies of all reports made in any reporting forms to insurance
companies.

       4.6.   Protection of Collateral.  All insurance expenses and all
expenses of protecting, storing, warehousing, insuring, handling, maintaining
and shipping the Collateral, any and all taxes imposed by any governmental
authority on any Collateral or in respect of the sale thereof shall be borne
and paid by Borrower.  If Borrower fails to promptly pay any portion thereof
when due, Lender may, at its option, but shall not be required to, pay the same
and charge the Loan Account therefor.  Borrower agrees to reimburse Lender
promptly therefor with interest accruing thereon daily at the Default Rate.
All sums so paid or incurred by Lender for any of the foregoing and all
reasonable costs and expenses (including reasonable attorneys' fees, legal
expenses, and court costs) which Lender may incur in enforcing or protecting
its Lien on or rights and interest in the Collateral or any of its rights or
remedies, together with interest at the Default Rate, shall be considered
Obligations hereunder secured by all Collateral.  Lender shall not be liable or
responsible in any way for the safekeeping of any Collateral or for any loss or
damage thereto (except for reasonable care in the custody thereof while any
Collateral is in Lender's actual possession) or for any diminution in the value
thereof, or for any act or default of any warehouseman, carrier, forwarding
agency, or other person whomsoever, but the same shall be at Borrower's sole
risk.

SECTION 5.    PROVISIONS RELATING TO ACCOUNTS

       5.1.   Representations, Warranties and Covenants.  With respect to all
Accounts, Borrower represents and warrants to Lender that Lender may rely, in
determining which Accounts are Eligible Accounts, on all statements and
representations made by Borrower with respect to any Account or Accounts, and,
unless otherwise indicated in writing to Lender, that with respect to each
Account:  it is genuine and in all respects what it purports to be, and it is
not evidenced by a judgment; it arises out of a completed, bona fide sale and
delivery of goods or rendition of services by Borrower in the ordinary course
of its business and in accordance with the terms and conditions of all purchase
orders, contracts or other documents relating thereto and forming a part of the
contract between Borrower and the Account Debtor; it is for a liquidated amount
maturing as stated in the duplicate invoice covering such sale or rendition of
services; such Account, and Lender's security interest therein, is not, and
will not be in the future, subject to any offset, Lien, deduction, defense,
dispute, counterclaim or any other adverse condition





LOAN AND SECURITY AGREEMENT - Page 26
<PAGE>   27
except for disputes resulting in returned goods where the amount in controversy
is deemed by Lender to be immaterial, and each such Account is absolutely owing
to Borrower and is not contingent in any respect or for any reason; Borrower
has made no agreement with any Account Debtor thereunder for any deduction
therefrom, except discounts or allowances which are granted by Borrower in the
ordinary course of its business for prompt payment and which are reflected in
the calculation of the net amount of each respective invoice related thereto;
there are no facts, events or occurrences which in any way impair the validity
or enforceability thereof or tend to reduce the amount payable thereunder from
the face amount of the invoice and statements delivered to Lender with respect
thereto; to the best of Borrower's knowledge, the Account Debtor thereunder is
Solvent and, at the time any contract or other document giving rise to the
Account was executed, such Account Debtor had the capacity to contract; and
Borrower has no knowledge of any fact or circumstance which would impair the
validity or collectibility of such Account.

       5.2.   Assignments, Records and Schedules of Accounts.  If requested to
do so by Lender, Borrower shall execute and deliver to Lender formal written
assignments of all of its Accounts weekly (or, if requested by Lender, daily),
together with copies of invoices or invoice registers related thereto.
Borrower shall keep accurate and complete records of its Accounts and all
payments and collections thereon and shall submit to Lender on a daily basis a
sales and collections report for the preceding day, in form satisfactory to
Lender.  On or before the fifteenth day of each month from and after the date
hereof, Borrower shall deliver to Lender, in form satisfactory to Lender, a
detailed aged trial balance of all Accounts existing as of the last day of the
preceding month, specifying the names, addresses, face value, dates of invoices
and due dates for each Account Debtor obligated on an Account so listed
("Schedule of Accounts"), and, upon Lender's request therefor, copies of proof
of delivery and the original copy of all documents, including, without
limitation, repayment histories and present status reports relating to the
Accounts so scheduled and such other matters and information relating to the
status of then existing Accounts as Lender shall reasonably request.  If any
amounts due and owing in excess of $50,000 are in dispute between Borrower and
any Account Debtor, Borrower shall provide Lender with written notice thereof
at the time of submission of the next Schedule of Accounts, explaining in
detail the reason for the dispute, all claims related thereto and the amount in
controversy.

       5.3.   Administration of Accounts.  Upon the granting of any discounts,
allowances or credits by Borrower that are not shown on the face of the invoice
for the Account involved, Borrower shall promptly report such discounts,
allowances or credits, as the case may be, to Lender and in no event later than
the time of its submission to Lender of the next Schedule of Accounts as
provided in Section 5.2.  If an Account includes a charge for any tax payable
to any governmental taxing authority, Lender is authorized, in its sole
discretion, to pay the amount thereof to the proper taxing authority for the
account of Borrower and to charge the Loan Account therefor.  Whether or not a
Default or an Event of Default has occurred, Lender shall have the right, at
any time or times hereafter, in the name of Lender, any designee of Lender or
Borrower, to verify the validity, amount or any other matter relating to any
Accounts by mail, telephone, telegraph or otherwise.  Borrower shall cooperate
fully with Lender in an effort to facilitate and promptly conclude any such
verification process.





LOAN AND SECURITY AGREEMENT - Page 27
<PAGE>   28
       5.4.   Collection of Accounts.  To expedite collection, Borrower shall
endeavor in the first instance to make collection of its Accounts for Lender.
All remittances received by Borrower on account of Accounts shall be held as
Lender's property by Borrower as trustee of an express trust for Lender's
benefit and Borrower shall immediately deposit same in the Dominion Account.
After the occurrence of an Event of Default, Lender shall have the right to
notify Account Debtors that Accounts have been assigned to Lender and to
collect Accounts directly in its own name and to charge the collection costs
and expenses, including reasonable attorneys' fees, to Borrower.  Lender has no
duty to protect, insure, collect or realize upon the Accounts or preserve
rights in them.

SECTION 6.    PROVISIONS RELATING TO INVENTORY

       6.1.   Representations, Warranties and Covenants.  With respect to
Inventory, Borrower represents and warrants to Lender that Lender may rely, in
determining which items of Inventory constitute Eligible Inventory, on all
statements and representations made by Borrower with respect to any Inventory
and that:  All Inventory is presently and will continue to be located at
Borrower's places of business listed on Exhibit B and will not be removed
therefrom except as authorized by Section 4.4 of this Agreement; no Inventory
is now, nor shall any Inventory at any time or times hereafter be, stored with
a bailee, warehouseman or similar party without Lender's prior written consent;
no Inventory is or will be consigned to any Person without Lender's prior
written consent; and no Inventory is or will be produced in violation of the
Fair Labor Standards Act.

       6.2.   Inventory Reports.  Borrower agrees to furnish Lender with
Inventory reports at such times as Lender may request, but at least once each
month.  Such reports shall be in form and detail satisfactory to Lender.
Borrower shall conduct a physical inventory no less frequently than annually
and shall provide to Lender a report based on each such physical inventory
promptly thereafter, together with such supporting information as Lender shall
in its discretion request.

       6.3.   Returns of Inventory.  If at any time or times hereafter any
Account Debtor returns any Inventory to Borrower the shipment of which
generated an Account on which such Account Debtor is obligated in excess of
$50,000, Borrower shall notify Lender of the same immediately, specifying the
reason for such return and the location and condition of the returned
Inventory.

SECTION 7.    PROVISIONS RELATING TO EQUIPMENT

       7.1.   Representations, Warranties and Covenants.  With respect to the
Equipment, Borrower represents, warrants and covenants to and with Lender that
the Equipment is in good operating condition and repair, and all necessary
replacements of and repairs thereto shall be made so that the value and
operating efficiency of the Equipment shall be maintained and preserved,
reasonable wear and tear excepted.  Borrower will not permit any of the
Equipment to become affixed to any real Property leased to Borrower so that an
interest arises therein under the





LOAN AND SECURITY AGREEMENT - Page 28
<PAGE>   29
real estate laws of the applicable jurisdiction unless the landlord of such
real Property has executed a landlord waiver or leasehold mortgage in favor of
Lender, and Borrower will not permit any of the Equipment to become an
accession to any personal Property other than Equipment subject to first
priority Liens in favor of Lender or subject to Permitted Liens.  Immediately
on request therefor by Lender, Borrower shall deliver to Lender any and all
evidence of ownership, if any, of any of the Equipment (including, without
limitation, certificates of title and applications for title).  Borrower shall
maintain accurate records itemizing and describing the kind, type, quality,
quantity and value of its Equipment and all dispositions made in accordance
with Section 7.2 hereof, and shall furnish Lender with a current schedule
containing the foregoing information on at least an annual basis and more often
if requested by Lender.

       7.2.   Dispositions of Equipment.  Borrower will not sell, lease or
otherwise dispose of or transfer any of the Equipment or any part thereof
without the prior written consent of Lender; provided, however, that the
foregoing restriction shall not apply, for so long as no Default or Event of
Default exists, to (A) dispositions of Equipment which, in the aggregate during
any consecutive twelve-month period, has a fair market value or book value,
whichever is less, of $100,000 or less, provided that all proceeds thereof are
turned over to Lender, or (B) replacements of Equipment that is substantially
worn, damaged or obsolete with Equipment of like kind, function and value,
provided that the replacement Equipment shall be acquired prior to or
concurrently with any disposition of the Equipment that is to be replaced, the
replacement Equipment shall be free and clear of Liens other than Permitted
Liens, Borrower shall give Lender at least five days prior written notice of
such disposition and Borrower shall turn over to Lender all proceeds realized
from any such disposition.

SECTION 8.    REPRESENTATIONS AND WARRANTIES

       8.1.   General Representations and Warranties.  To induce Lender to
enter into this Agreement and to make advances hereunder, Borrower warrants,
represents and covenants to Lender as follows:

              (A)    Borrower is a corporation duly organized, validly existing
and in good standing under the laws of the State of Nevada; has duly qualified
and is authorized to do business and is in good standing as a foreign
corporation in all states and jurisdictions where the character of its
Properties or the nature of its activities make such qualification necessary;
and has not been known as or used any corporate, fictitious or trade names in
the past seven years except as disclosed on Exhibit C attached hereto and made
a part hereof.

              (B)    Borrower has the right and power and is duly authorized to
enter into, deliver and perform this Agreement and each of the Other Agreements
to which it is a party, and this Agreement is, and each of the Other Agreements
when delivered under this Agreement will be, a legal, valid and binding
obligation of Borrower enforceable against it in accordance with their
respective terms.





LOAN AND SECURITY AGREEMENT - Page 29
<PAGE>   30
              (C)    Borrower is not engaged principally, or as one of its
important activities, in the business of purchasing or carrying "margin stock"
(within the meaning of Regulation G or U of the Board of Governors of the
Federal Reserve System), and no part of the proceeds of any Loans to Borrower
will be used to purchase or carry any margin stock or to extend credit to
others for the purpose of purchasing or carrying any margin stock, or be used
for any purpose which violates or is inconsistent with the provisions of
Regulations G, T, U or X of said Board of Governors.

              (D)    Borrower has, and is in good standing with respect to, all
governmental consents, approvals, authorizations, permits, certificates,
inspections, and franchises which materially affect its ability to conduct its
business as heretofore or proposed to be conducted by it and to own or lease
and operate its Properties as now owned or leased by it.

              (E)    Borrower owns or possesses all the patents, trademarks,
service marks, trade names, copyrights and licenses necessary for the present
and planned future conduct of its business without any known conflict with the
rights of others.

              (F)    Except as set forth on Exhibit D attached hereto and made
a part hereof, there are no actions, suits, proceedings or investigations
pending, or to the knowledge of Borrower, threatened, against or affecting
Borrower or any of its Properties in any court or before any governmental
authority or arbitration board or tribunal, and no action, suit, proceeding or
investigation shown on Exhibit D involves the possibility of materially and
adversely affecting the Properties or condition (financial or otherwise) of
Borrower or the ability of Borrower to perform this Agreement.

              (G)    Borrower has good, indefeasible and marketable title to
and fee simple ownership of, or valid and subsisting leasehold interests in,
all of its real Property, and good title to all of its other Property, in each
case, free and clear of all Liens except Permitted Liens.

              (H)    The balance sheet of Borrower and such other Persons
described therein as of March 31, 1997, and the related statements of income,
for the periods ended on such dates, have been prepared, to the best of
Borrower's knowledge, in accordance with GAAP (except for changes in
application in which Borrower's independent certified public accountants
concur), and present fairly the financial positions of Borrower at such dates
and the results of Borrower's operations for such periods.  Since March 31,
1997, there has been no material change in the condition, financial or
otherwise, of Borrower and such other Persons as shown on the balance sheet as
of such date and no change in the aggregate value of Equipment and real
Property owned by Borrower or such other Persons, except changes in the
ordinary course of business, none of which individually or in the aggregate has
been materially adverse.  The fiscal year of Borrower for accounting purposes
ends on December 31 of each year.

              (I)    There is no fact which Borrower has failed to disclose to
Lender in writing which materially affects adversely or, so far as Borrower can
now foresee, will materially affect adversely the Properties, business,
prospects, profits, or condition (financial or otherwise) of Borrower or the
ability of Borrower to perform this Agreement.





LOAN AND SECURITY AGREEMENT - Page 30
<PAGE>   31
              (J)    Borrower has not received any notice to the effect that it
is not in full compliance with any of the requirements of ERISA and the
regulations promulgated thereunder.  No fact or situation that could result in
a material adverse change in the financial condition of Borrower (including,
but not limited to, any Reportable Event or Prohibited Transaction) exists in
connection with any Plan.  Borrower has no withdrawal liability in connection
with a Multi-Employer Plan.

              (K)    Borrower has filed all federal, state and local tax
returns and other reports it is required by law to file and has paid, or made

business operations and leaseholds are in compliance in all material respects
with, the provisions of all federal, state and local laws, rules and
regulations applicable to Borrower, its Properties or the conduct of its
business.

              (M)    No Default or Event of Default will exist or result from
the execution and delivery of this Agreement or Borrower's performance
hereunder.

              (N)    There are no claims for brokerage commissions, finder's
fees or investment banking fees in connection with the transactions
contemplated by this Agreement.

       8.2.   Reaffirmation and Survival of Representations.  Each request for
a Loan made by Borrower pursuant to this Agreement or any of the Other
Agreements shall constitute (A) an automatic representation and warranty by
Borrower to Lender that there does not then exist any Default or Event of
Default, and (B) a reaffirmation as of the date of said request of all of the
representations and warranties of Borrower contained in this Agreement and the
Other Agreements are true in all material respects, except for any changes in
the nature of Borrower's business or operations that would render the
information contained in any exhibit hereto either materially inaccurate or
materially incomplete, so long as Lender has consented to such changes or such
changes are expressly permitted by this Agreement.  Borrower covenants,
warrants and represents to Lender that all representations and warranties of
Borrower contained in this Agreement or any of the Other Agreements shall be
true at the time of Borrower's execution of this Agreement and the Other
Agreements, and shall survive the execution, delivery and acceptance thereof by
Lender and the parties thereto and the closing of the transactions described
therein or related thereto.

SECTION 9.    COVENANTS AND CONTINUING AGREEMENTS

       9.1.   Affirmative Covenants.  During the term of this Agreement, and
thereafter for so long as there are any Obligations to Lender, Borrower
covenants that, unless otherwise consented to by Lender in writing, it shall:





LOAN AND SECURITY AGREEMENT - Page 31

              (A)    Pay and discharge all taxes, assessments and governmental
charges upon it, its income and Properties as and when such taxes, assessments
and charges are due and payable, except and to the extent only that such taxes,
assessments and charges are being actively contested in good faith and by
appropriate proceedings, Borrower maintains adequate reserves on its books
there for and the nonpayment of such taxes does not result in a Lien upon any
Properties or Borrower other than a Permitted Lien.  Borrower shall also pay
and discharge any lawful claims which, if unpaid, might become a Lien against
any of Borrower's Properties except for Permitted Liens.

              (B)    File all federal, state and local tax returns and other
reports Borrower is required by law to file and maintain adequate reserves for
the payment of all taxes, assessments, governmental charges, and levies imposed
upon it, its income, or its profits, or upon any Property belonging to it.

              (C)    Pay to Lender, on demand, any and all fees, costs or
expenses which Lender pays to a bank or other similar institution (including,
without limitation, any reasonable fees paid by Lender to any Participating
Lender) arising out of or in connection with (i) the forwarding to Borrower or
any other Person on behalf of Borrower, by Lender of proceeds of loans made by
Lender to Borrower pursuant to this Agreement and (ii) the depositing for
collection, by Lender, of any check or item of payment received or delivered to
Lender on account of the Obligations.

              (D)    Preserve and maintain its separate corporate existence and
all rights, privileges, and franchises in connection therewith, and maintain
its qualification and good standing in all states in which such qualification
is necessary.

              (E)    Maintain its Properties in good condition and make all
necessary renewals, repairs, replacements, additions and improvements thereto.

              (F)    Comply with all laws, ordinances, governmental rules and
regulations to which it is subject, and obtain and keep in force any and all
licenses, permits, franchises, or other governmental authorizations necessary
to the ownership of its Properties or to the conduct of its business, which
violation or failure to obtain might materially and adversely affect the
Properties or condition (financial or otherwise) of Borrower.

              (G)    (i) At all times make prompt payment of contributions
required to meet the minimum funding standards set forth in ERISA with respect
to each Plan; (ii) promptly after the filing thereof, furnish to Lender copies
of any annual report required to be filed pursuant to ERISA in connection with
each Plan and any other employee benefit plan of it and its Affiliates subject
to said Section; (iii) notify Lender as soon as practicable of any Reportable
Event and of any additional act or condition arising in connection with any
Plan which Borrower believes might constitute grounds for the termination
thereof by the Pension Benefit Guaranty Corporation or for the appointment by
the appropriate United States district court of a trustee to administer the
Plan; and (iv) furnish to Lender, promptly upon Lender's request therefor, such





LOAN AND SECURITY AGREEMENT - Page 32

additional information concerning any Plan or any other such employee benefit
plan as may be reasonably requested.

              (H)    Keep adequate records and books of account with respect to
its business activities in which proper entries are made in accordance with
GAAP (to the best of Borrower's knowledge) reflecting all its financial
transactions.

              (I)    Permit representatives of Lender, from time to time, as
often as may be reasonably requested, but only during normal business hours, to
visit and inspect the Properties of Borrower, inspect and make extracts from
its books and records, and discuss with its officers, its employees and its
independent accountants, Borrower's business, assets, liabilities, financial
condition, business prospects and results of operations.

              (J)    Cause to be prepared and furnished to Lender the following

basis, unless Parent's certified public accountants concur in any change
therein and such change is disclosed to Lender and are consistent with GAAP):

fiscal year of Parent, unqualified audited consolidated financial statements of
Parent and its Subsidiaries (including Borrower) as of the end of such year,

such accounting firm concurs) and unaudited consolidated and consolidating
financial statements of Parent and its Subsidiaries (including Borrower),
certified by the principal financial officer of Parent as prepared in
accordance with GAAP to the best of his knowledge and fairly presenting the

              (R)    There shall occur any default or event of default under
any agreement, document or instrument evidencing or executed in connection with
any Subordinated Debt.

       11.2.  Acceleration of the Obligations.  Without in any way limiting the
right of Lender to demand payment of any portion of the Obligations payable on
demand in accordance with Section 3.4 hereof, upon and at any time after the
occurrence of an Event of Default, all or any portion of the Obligations due or
to become due from Borrower to Lender (whether under this Agreement, any Other
Agreement or otherwise) shall, at Lender's option, become at once due and
payable without presentment, demand, protest, notice of dishonor, notice of
default, notice of intent to accelerate, notice of acceleration, or any other
notice whatsoever, and Borrower shall forthwith pay to Lender, in addition to
any and all sums and charges due, the entire principal of and interest accrued
on the Obligations; provided, however, that upon the occurrence of an Event of
Default specified in Section 11.1(D) hereof, all of the Obligations shall
become due and payable without declaration, notice or demand by Lender.

       11.3.  Remedies.  Upon and after the occurrence of an Event of Default,
Lender shall have and may exercise from time to time the following rights and
remedies:

              (A)    All of the rights and remedies of a secured party under
the Code or under other applicable law, and all other legal and equitable
rights to which Lender may be entitled, all of which rights and remedies shall
be cumulative, and none of which shall be exclusive, and shall be in addition
to any other rights or remedies contained in this Agreement or any of the Other
Agreements.

              (B)    The right to take immediate possession of the Collateral,
and (i) to require Borrower to assemble the Collateral, at Borrower's expense,
and make it available to Lender at a place designated by Lender which is
reasonably convenient to both parties, and (ii) to enter any of the premises of
Borrower or wherever any of the Collateral shall be located, and to keep and
store the same on said premises until sold (and if said premises be the
Property of Borrower, Borrower agrees not to charge Lender for storage
thereof).

              (C)    The right to sell or otherwise dispose of all or any
Inventory or Equipment in its then condition, or after any further
manufacturing or processing thereof, at public or private sale or sales, with
such notice as may be required by law, in lots or in bulk, for cash or on
credit, all as Lender, in its discretion, may deem advisable.  Borrower agrees
that fifteen days written notice to Borrower of any public or private sale or
other disposition of such Collateral shall be reasonable notice thereof, and
such sale shall be at such locations as Lender may designate in said notice.
Lender shall have the right to conduct such sales on Borrower's premises,
without charge therefor, and such sales may be adjourned from time to time in
accordance with applicable law.  Lender shall have the right to sell, lease or
otherwise dispose of such Collateral, or any part thereof, for cash, credit or
any combination thereof, and Lender may purchase all or any part of such
Collateral at public or, if permitted by law, private sale and, in lieu of
actual payment of such purchase price, may set-off the amount of such price
against the Obligations.

              (D)    Lender is hereby granted a license or other right to use,
without charge, Borrower's labels, patents, copyrights, rights of use of any
name, trade secrets, tradenames, trademarks and advertising matter, or any
Property of a similar nature, as it pertains to the





LOAN AND SECURITY AGREEMENT - Page 43
<PAGE>   44
Collateral, in advertising for sale and selling any Collateral and Borrower's
rights under all licenses and all franchise agreements shall inure to Lender's
benefit.

              (E)    The proceeds realized from the sale of any Collateral may
be applied, after allowing two Business Days for collection, first to the
costs, expenses and reasonable attorneys' fees incurred by Lender in collecting
the Obligations, in enforcing Lender's rights under the Loan Documents and in
collecting, retaking, completing, protecting, removing, storing, advertising
for sale, selling and delivering any of the Collateral; secondly, to interest
due upon any of the Obligations; and thirdly, to the principal of the
Obligations.  If any deficiency shall arise, Borrower shall remain liable to
Lender therefor.

       11.4.  Remedies Cumulative; No Waiver.  All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the Other Agreements, or in any
document referred to herein or contained in any agreement supplementary hereto
or in any schedule given to Lender or contained in any other agreement between
Lender and Borrower, heretofore, concurrently, or hereafter entered into, shall
be deemed cumulative to and not in derogation or substitution of any of the
terms, covenants, conditions, or agreements of Borrower herein contained.  The
failure or delay of Lender to exercise or enforce any rights, Liens, powers or
remedies hereunder or under any of the aforesaid agreements or other documents
or security or Collateral shall not operate as a waiver of such Liens, rights,
powers and remedies, but all such Liens, rights, powers, and remedies shall
continue in full force and effect until all Loans and all other Obligations
owing or to become owing from Borrower to Lender shall have been fully
satisfied, and all Liens, rights, powers, and remedies herein provided for are
cumulative and none are exclusive.

SECTION 12.   MISCELLANEOUS

       12.1.  Power of Attorney. Borrower hereby irrevocably designates, makes,
constitutes and appoints Lender (and all Persons designated by Lender) as
Borrower's true and lawful attorney (and agent-in-fact) and Lender, or Lender's
agent, may, without notice to Borrower and in either Borrower's or Lender's
name, but at the reasonable cost and expense of Borrower:

              (A)    At such time or times hereafter as Lender or said agent
may determine, endorse Borrower's name on any checks, notes, acceptances,
drafts, money orders or any other evidence of payment or proceeds of the
Collateral which come into the possession of Lender or under Lender's control;
and

              (B)    At such time or times upon or after the occurrence of an
Event of Default as Lender or its agent may determine:  (i) demand and enforce
payment of the Accounts by legal proceedings or otherwise and exercise
generally all of Borrower's rights and remedies with respect to the collection
of the Accounts; (ii) settle, adjust, compromise, discharge or release any of
the Accounts or other Collateral or any legal proceedings brought to collect
any of the Accounts or other Collateral; (iii) prepare, file and sign
Borrower's name to a proof of claim in bankruptcy or similar document against
any Account Debtor or to any notice of lien, assignment or satisfaction of lien
or similar document in connection with any of the Collateral; (iv) receive





LOAN AND SECURITY AGREEMENT - Page 44
<PAGE>   45
and open all mail addressed to Borrower and to notify postal authorities to
change the address for delivery thereof to such address as Lender may
designate; (v) endorse the name of Borrower upon any of the items of payment or
proceeds relating to any Collateral and deposit the same to the account of
Lender on account of the Obligations; (vi) endorse the name of Borrower upon
any chattel paper, document, instrument, invoice, freight bill, bill of lading
or similar document or agreement relating to the Accounts, Inventory and any
other Collateral; (vii) use Borrower's stationery and sign the name of Borrower
to verifications of the Accounts and notices thereof to Account Debtors; (viii)
make and adjust claims under policies of insurance; and (ix) do all other acts
and things necessary, in Lender's reasonable determination, to fulfill
Borrower's obligations under this Agreement.

       12.2.  Indemnity.  Borrower hereby agrees to indemnify Lender and hold
Lender harmless from and against any liability, loss, damage, suit, action or
proceeding ever suffered or incurred by Lender as the result of Borrower's
failure to observe, perform or discharge Borrower's duties hereunder.  Without
limiting the generality of the foregoing, this indemnity shall extend to any
claims asserted against Lender by any Person under any Environmental Laws or
similar laws by reason of Borrower's or any other Person's failure to comply
with laws applicable to solid or hazardous waste materials or other toxic
substances, but this indemnity shall specifically exclude liability for breach
of any Environmental Laws caused solely and directly by Lender.
Notwithstanding any contrary provision in this Agreement, the obligation of
Borrower under this Section 12.2 shall survive the payment in full of the
Obligations and the termination of Lender's obligation to make Revolving Credit
Loans.

       12.3.  Modification of Agreement.  This Agreement and the Other
Agreements may not be modified, altered or amended, except by an agreement in
writing signed by Borrower and Lender.

       12.4   Reimbursement of Expenses.  If, at any time or times prior or
subsequent to the date hereof, regardless of whether or not an Event of Default
then exists or any of the transactions contemplated hereunder are concluded,
Lender employs counsel for advice or other representation, or incurs legal
expenses or other costs or out-of-pocket expenses in connection with:  (A) the
negotiation and preparation of this Agreement or any of the Other Agreements,
any amendment of or modification of this Agreement or any of the Other
Agreements; (B) the reasonable administration of this Agreement or any of the
Other Agreements and the transactions contemplated hereby and thereby; (C) any
litigation, contest, dispute, suit, proceeding or action (whether instituted by
Lender, Borrower or any other Person) in any way relating to the Collateral,
this Agreement or any of the Other Agreements or Borrower's affairs (other than
litigation in which Borrower is the prevailing party and in which Lender is
adverse to Borrower); (D) any attempt to enforce any rights of Lender against
Borrower or any other Person which may be obligated to Lender by virtue of this
Agreement or any of the Other Agreements, including, without limitation, the
Account Debtors (other than litigation in which Borrower is the prevailing
party and in which Lender is adverse to Borrower); or (E) any attempt to
inspect, verify, protect, preserve, restore, collect, sell, liquidate or
otherwise dispose of or realize upon the Collateral; then, in any such event,
the reasonable attorneys' fees arising from such services and all expenses,
costs, charges and other fees of such counsel or of Lender or relating to any
of the





LOAN AND SECURITY AGREEMENT - Page 45
<PAGE>   46
events or actions described in this Section shall be payable, on demand, by
Borrower to Lender and shall be additional Obligations hereunder secured by the
Collateral.  Additionally, if any taxes (excluding taxes imposed upon or
measured by the net income of Lender) shall be payable on account of the
execution or delivery of this Agreement, or the execution, delivery, issuance
or recording of any of the Other Agreements, or the creation of any of the
Obligations hereunder, by reason of any existing or hereafter enacted federal
or state statute, Borrower will pay all such taxes, including, but not limited
to, any interest and penalties thereon, and will indemnify and hold Lender
harmless from and against liability in connection therewith.  Borrower shall
have no obligation to pay the legal expenses or other costs incurred by a
Participating Lender or by Lender in connection with any sale or attempted sale
of any interest herein to a Participating Lender.

       12.5.  Indulgences Not Waivers.  Lender's failure, at any time or times
hereafter, to require strict performance by Borrower of any provision of this
Agreement shall not waive, affect or diminish any right of Lender thereafter to
demand strict compliance and performance therewith.  Any suspension or waiver
by Lender of an Event of Default by Borrower under this Agreement or any of the
Other Agreements shall not suspend, waive or affect any other Event of Default
by Borrower under this Agreement or any of the Other Agreements, whether the
same is prior or subsequent thereto and whether of the same or of a different
type.  None of the undertakings, agreements, warranties, covenants and
representations of Borrower contained in this Agreement or any of the Other
Agreements and no Event of Default by Borrower under this Agreement or any of
the Other Agreements shall be deemed to have been suspended or waived by
Lender, unless such suspension or waiver is by an instrument in writing
specifying such suspension or waiver and is signed by a duly authorized
representative of Lender and directed to Borrower.

       12.6.  Severability.  Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Agreement.

       12.7.  Successors and Assigns; Participations by Lender.  This Agreement
and the Other Agreements shall be binding upon and inure to the benefit of the
successors and assigns of Borrower and Lender; provided, however, that Borrower
may not sell, assign or transfer any interest in this Agreement or any of the
Other Agreements, or any portion thereof, including, without limitation,
Borrower's rights, title, interests, remedies, powers and duties hereunder or
thereunder.  Any purported assignment by Borrower in violation of this Section
12.7 shall be void, without Lender's prior written consent.  Borrower hereby
consents to Lender's participation, sale, assignment, transfer or of the
disposition, at any time or times hereafter, of this Agreement, any of the
Other Agreements, or any other Obligations, or of any portion hereof or
thereof, including, without limitation, Lender's rights, title, interests,
remedies, powers, and duties hereunder or thereunder.  In the case of an
assignment, the assignee shall have, to the extent of such assignment, the same
rights, benefits and obligations as it would have if it were the original
"Lender" hereunder and Lender shall be relieved of all obligations hereunder
upon any such





LOAN AND SECURITY AGREEMENT - Page 46
<PAGE>   47
assignment.  In the case of a participation, each Participating Lender shall be
entitled to receive all information received by Lender regarding the credit-
worthiness of Borrower, including, without limitation, information required to
be disclosed to a participant pursuant to Banking Circular 181 (Rev., August 2,
1984), issued by the Comptroller of the Currency (whether such Participating
Lender is subject to the circular or not).

       12.8.  Cumulative Effect; Conflict of Terms.  The provisions of the
Other Agreements are hereby made cumulative with the provisions of this
Agreement.  Except as otherwise provided in Section 3.4 of this Agreement and
except as otherwise provided in any of the Other Agreements by specific
reference to the applicable provision of this Agreement, if any provision
contained in this Agreement is in direct conflict with, or inconsistent with,
any provision in any of the Other Agreements, the provision contained in this
Agreement shall govern and control.

       12.9.  Execution in Counterparts.  This Agreement may be executed in any
number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to
be an original and all of which counterparts taken together shall constitute
but one and the same instrument.

       12.10. Notice.  Except as otherwise provided herein, all notices,
requests and demands to or upon a party hereto shall be in writing and shall be
sent by certified or registered mail, return receipt requested, personal
delivery against receipt, or by telegraph or telex and, unless otherwise
expressly provided herein, shall be deemed to have been validly served, given

obtained under this Agreement or any of the Other Agreements as a condition to

withhold such consent in its sole and absolute discretion (unless otherwise
expressly provided herein) and to condition its consent upon the giving of
additional collateral security for the Obligations, the payment of money or any
other matter.

       12.12. Demand Obligations.  Nothing in this Agreement shall affect or
abrogate the demand nature of any portion of the Obligations expressly made

same, and the occurrence of an Event of Default shall not be a prerequisite for
Lender's requiring payment of such Obligations.

       12.13. Time of Essence.  Time is of the essence of this Agreement and
the Other Agreements.

       12.14. Entire Agreement.  This Agreement and the Other Agreements,

       12.15. Interpretation.  No provision of this Agreement or any of the

disadvantage of any party hereto by any court or other governmental or judicial
authority by reason of such party having or being deemed to have structured,

TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SAME IN ANY OTHER
APPROPRIATE FORUM OR JURISDICTION.

         FOR VALUE RECEIVED, the undersigned (hereinafter "Borrower"), hereby
promises to pay to the order of FLEET CAPITAL CORPORATION, a Rhode Island
corporation (hereinafter "Lender") at its office located at 2711 North Haskell,
Suite 2100, LB 21, Dallas, Texas 75204, or at such other location as Lender may
request, in such coin or currency of the United States which shall be legal
tender in payment of all debts and dues, public and private, at the time of
payment, the principal sum of FIVE HUNDRED THOUSAND AND NO/100 DOLLARS
($500,000.00), together with interest on the unpaid principal balance from
day-to-day remaining computed from the date of advance until maturity at a
variable rate per annum equal to the lesser of (i) 0.50% above the Base Rate
(as hereinafter defined) (the "Annual Term Rate"), or (ii) the Maximum Legal
Rate (as hereinafter defined).

         This Secured Promissory Note (this "Note") is the Term Note referred
to in, and is issued pursuant to, that certain Loan and Security Agreement,
dated on or about June __, 1997 (as amended, restated or renewed from time to
time, the "Loan Agreement") and is entitled to all of the benefits and security
of the Loan Agreement. All of the terms, covenants and conditions of the Loan
Agreement and all other instruments evidencing or securing the indebtedness
hereunder (including, without limitation, the "Security Documents" as defined
in the Loan Agreement) (hereinafter collectively referred to as the "Loan
Documents") are hereby made a part of this Note and are deemed incorporated
herein in full.  All capitalized terms used herein, unless otherwise
specifically defined in this Note, shall have the meanings ascribed to them in
the Loan Agreement.

         For the purposes of this Note, the term "Base Rate" shall mean the
rate of interest established by Fleet National Bank from time to time as its
"base rate" for commercial loans, whether or not such rate is the lowest rate
charged by said bank to its most preferred borrowers; and, if the base rate for
commercial loans is discontinued by said bank as a standard, a comparable
reference rate designated by said bank as a substitute therefor shall be the
"Base Rate".  After the date hereof, the rate of interest in effect hereunder
shall be increased or decreased, as the case may be, by an amount equal to any
increase or decrease in the Base Rate, with such adjustments to be effective as
of the opening of business on the date that any such change in the Base Rate
becomes effective. The Base Rate in effect on the date hereof shall be the Base
Rate effective as of the opening of business on the date hereof, but if this
Note is executed on a day that is not a Business Day, the Base Rate in effect
on the date hereof shall be the Base Rate effective as of the opening of
business on the last business day immediately preceding the date hereof.
Interest due at the Maximum Legal Rate shall be calculated on the basis of
actual days elapsed over a year of 365 or 366 days, as the case may be.

         Upon and after the occurrence of an Event of Default, and during the
continuation thereof, the principal amount of this Note shall bear interest at
a fluctuating rate per annum equal to the lesser of (i) 3.0% above the Base
Rate (the "Default Rate"), calculated daily (computed on the actual days
elapsed over a year of 360 days), or (ii) the Maximum Legal Rate.

         If at any time the amount of such interest computed on the basis of
the Annual Term Rate or the Default Rate, whichever is applicable (the
"Applicable Rate"), would exceed the amount of such interest computed upon the
basis of the maximum rate of interest permitted by applicable state or federal
law in effect from time to time hereafter (the "Maximum Legal Rate"), the
interest payable under this Note shall be computed upon the basis of the
Maximum Legal Rate, but any subsequent reduction in the Applicable Rate shall
not reduce such interest thereafter payable hereunder below the amount computed
on the basis of the Maximum Legal Rate until the aggregate amount of such
interest accrued and payable under this Note equals the total amount of
interest which would have accrued if such interest had been at all times
computed solely on the basis of the Applicable Rate. Unless preempted by
federal law, the Applicable Rate from time to time in effect hereunder may not
exceed the "indicated ceiling rate" from time to time in effect under Tex. Rev.
Civ. Stat. Ann. art. 5069-1.04(c) (Vernon 1987). If the applicable state or
federal law is amended in the future to allow a greater rate of interest to be
charged under this Note than is presently allowed by applicable state or
federal law, then the limitation of interest hereunder shall be increased to
the maximum rate of interest allowed by applicable state or federal law as
amended, which increase shall be effective hereunder on the effective date of
such amendment, and all interest charges owing to Lender by reason thereof
shall be payable at the same date and in the same manner as accrued interest on
this Note is generally payable pursuant to the provisions of this Note.

         The principal amount of and all accrued interest on this Note shall be
due and payable on the dates and in the manner hereinafter set forth:

                 (a)      Interest shall be due and payable monthly, in
         arrears, on the first day of each month, commencing on the first day
         of the month immediately succeeding the date of this Note, and
         continuing on the first day of each month thereafter until such time
         as the full principal balance, together with all other amounts owing
         hereunder, shall have been paid in full;

                 (b)      Principal shall be due and payable in equal monthly
         installments of $8,300.00 each, commencing on August l, 1998, and
         continuing on the first day of each month thereafter; and

                 (c)      The entire remaining principal amount then
         outstanding, together with any unpaid interest and any and all other
         amounts due hereunder, shall be due and payable on the last day of the
         Original Term or on any earlier termination of the Loan Agreement
         pursuant to Section 3.3 thereof.





                                      2

         This Note shall be subject to mandatory prepayment in accordance with
the provisions of Section 2.2 of the Loan Agreement.

         Borrower (i) shall also prepay this Note in full in connection with
any termination of the Loan Agreement pursuant to Section 3.3 of the Loan
Agreement, and (ii) may prepay this Note in part or in full upon ten (10) days'
prior written notice to Lender, provided that such partial prepayment is made
solely from the internal cash flow from Borrower's ordinary business
operations; provided, however, that each such prepayment described above in
this paragraph shall be made together with accrued interest on the principal
amount so prepaid at the payment date, plus a premium equal to 0.5% of the
principal amount prepaid.

         All partial prepayments, whether mandatory or voluntary, shall be
applied to installments of principal in the inverse order of their maturities.

         Upon or after the occurrence of an Event of Default, Lender shall have
all of the rights and remedies set forth in Section 11 of the Loan Agreement,
including the right to declare the then outstanding principal balance and
accrued interest hereof to be and the same shall thereupon become, immediately
due and payable without notice to or demand upon Borrower, all of which
Borrower hereby expressly waives.

         No agreements, conditions, provisions or stipulation contained in this
Note, the Loan Agreement or any other instrument, document or agreement between
Borrower and Lender or default of Borrower, or the exercise by Lender of the
right to accelerate the payment of the maturity of principal and interest, or
to exercise any option whatsoever contained in this Note or any other Loan
Document, or the arising of any contingency whatsoever, shall entitle Lender to
contract for, charge, or receive, in any event, interest exceeding the Maximum
Legal Rate. In no event shall Borrower be obligated to pay interest exceeding
such Maximum Legal Rate and all agreements, conditions or stipulations, if any,
which may in any event or contingency whatsoever operate to bind, obligate or
compel Borrower to pay a rate of interest exceeding the Maximum Legal Rate,
shall be without binding force or effect, at law or in equity, to the extent
only of the excess of interest over such Maximum Legal Rate. In the event any
interest is contracted for, charged or received in excess of the Maximum Legal
Rate ("Excess Interest"), Borrower acknowledges and stipulate that any such
contract, charge, or receipt shall be the result of an accident and bona fide
error, and that any Excess Interest received by Lender shall be applied, first,
to reduce the principal then unpaid hereunder; second, to reduce the other
Obligations; and third, returned to Borrower, it being the intention of the
parties hereto not to enter at any time into a usurious or otherwise illegal
relationship. Borrower recognizes that, with fluctuations in the Applicable
Annual Rate and the Maximum Legal Rate, such a result could inadvertently
occur. By the execution of this Note, Borrower covenants that (i) the credit or
return of any Excess Interest shall constitute the acceptance by Borrower of
such Excess Interest, and (ii) Borrower shall not seek or pursue any other
remedy, legal or equitable, against Lender, based in whole or in part upon
contracting for, charging or receiving of any interest in excess of the maximum
rate authorized by applicable law.  For the purpose of determining whether or
not any Excess Interest has been contracted for, charged or received by Lender,
all interest at any time contracted for, charged or received by Lender in
connection with this Note shall be amortized, prorated, allocated and spread in





                                      3

equal parts during the entire term of this Note.

         Time is of the essence of this Note. Unless otherwise provided in the
Loan Agreement, Borrower, for itself and its legal representatives, successors
and assigns, expressly waives, to the fullest extent permitted by Applicable
Law, presentment, demand, protest, notice of dishonor, notice of non-payment,
notice of intent to accelerate, notice of acceleration, notice of maturity,
notice of protest, presentment for the purpose of accelerating maturity,
diligence in collection, and the benefit of any exemption or insolvency laws.

         If this Note is collected by or through an attorney at law, Borrower
shall be obligated to pay, in addition to the principal balance and accrued
interest hereof, reasonable attorney's fees and court costs, and any other
charges for which Borrower is responsible under the Loan Agreement and other
Loan Documents.

         Wherever possible, each provision of this Note shall be interpreted in
such manner as to be effective and valid under Applicable Law, but if any
provision of this Note shall be prohibited or invalid under Applicable Law,
such provision shall be ineffective to the extent of such prohibition or
invalidity without invalidating the remainder of such provision or remaining
provisions of this Note. No delay or failure on the part of Lender in the
exercise of any right or remedy hereunder shall operate as a waiver thereof,
nor as an acquiescence in any default, nor shall any single or partial exercise
by Lender of any right or remedy preclude any other right or remedy. Lender, at
its option, may enforce its rights against any collateral securing this Note
without enforcing its rights against Borrower, any guarantor of the
indebtedness evidenced hereby or any other property or indebtedness due or to
become due to Borrower.  Borrower agrees that, without releasing or impairing
Borrower's liability hereunder, Lender may at any time release, surrender,
substitute or exchange any collateral securing this Note and may at any time
release any party primarily or secondarily liable for the indebtedness
evidenced by this Note.

         This Note shall be governed by, and construed and enforced in
accordance with, the laws of the State of Texas.

         IN WITNESS WHEREOF, Borrower has caused this Note to be duly executed
and delivered in Dallas, Texas, on the date first above written.

          the Mortgaged Property under any applicable Environmental Law, or to

          Grantor provides to a governmental authority relating to instances of
          non-compliance with an applicable Environmental Law; and

                                (vi)       any written application Grantor
          provides to a governmental authority to obtain or amend a permit or

investigation, site monitoring, containment, cleanup, removal, restoration or
other remedial work of any kind or nature (the "Remedial Work") is required to

Hazardous Substance in violation of applicable Environmental Laws or in
connection with remediation liability arising under applicable Environmental

 Section 5.2.          Representations and Warranties Relating to Environmental
                                   Matters.

Grantor represents and warrants to Beneficiary that, except as previously
disclosed to Beneficiary in writing:

                      (A)       No Existing Violation. Neither the Mortgaged
Property nor the Grantor is in violation of or subject to any existing, pending
or, to the knowledge of Grantor, overtly threatened investigation by any
governmental authority under any Environmental Law.

                      (B)       No Permits Required. Grantor has not acquired
and is not required by any applicable Environmental Law to obtain any permits
or license to construct or use any improvements, fixtures or equipment forming
a part of the Mortgaged Property except such permits or licenses as have been
obtained.

                      (C)       Previous Uses. Grantor or its environmental
advisors has made diligent inquiry into previous uses and ownership of the
Mortgaged Property, and based upon such inquiry has no knowledge of any
Hazardous Substance disposed of or released on or to the Mortgaged Property.

                      (D)       Use by Grantor. Grantor's or any Lessee's
prior, present and intended use of the Mortgaged Property will not result in
the disposal or release of any Hazardous Substance on or to the Mortgaged
Property except in compliance with applicable law.

                      (E)       Underground Storage.  No underground storage
tanks, whether or not containing any Hazardous Substances, are located on or
under the Mortgaged Property.

          Section 5.3.          Environmental Risk Assessment.  At any time (A)
that Beneficiary reasonably believes that Hazardous Substances have been
disposed of on, or have been released to or from any of the Mortgaged Property
and such release or disposal





                                     12
<PAGE>   80
may reasonably be expected to result in liability to Grantor under applicable
Environmental Laws (a "Triggering Event"), or (B) after an Event of Default
arising under Article V, within 30 days after a written request therefor by
Beneficiary, Grantor shall deliver to Beneficiary a report prepared at
Grantor's cost and expense by an environmental consultant acceptable to
Beneficiary, detailing the results of an environmental investigation with
respect to the Triggering Event or the matter resulting in the Event of
Default, including results of any soil and ground water samples that may have
been taken in connection with such investigation.


                                   ARTICLE VI

                       RESPECTING REMEDIES OF BENEFICIARY

          Section 6.1.  Remedies. Upon the occurrence of an Event of Default,
Beneficiary may, at Beneficiary's option, do any one or more of the following
(upon such notice, if any, as may be expressly provided for in the Loan
Documents):

                      (A)       Acceleration.  Beneficiary may, without notice,
demand, presentment, notice of intention to accelerate or acceleration, protest
or notice of protest, all of which are hereby waived by Grantor, declare the
entire unpaid balance of the Secured Indebtedness immediately due and payable,
and upon such declaration the entire unpaid balance of the Secured Indebtedness
shall be immediately due and payable.

                      (B)       Foreclosure. Beneficiary may request Trustee to
foreclose the Lien of this Deed of Trust and to sell the Mortgaged Property, or
any part thereof, at the location, at such time or from time to time, and in
such manner as may be permitted by applicable law, including, without
limitation, Chapter 51 of the Texas Property Code, as amended from time to
time.

                      After such sale, Trustee shall make to the purchaser or
purchasers thereunder good and sufficient assignments, deeds, bills of sale,
and other instruments, in the name of Grantor, conveying the Mortgaged
Property, or part thereof, so sold to the purchaser or purchasers with general
warranty of title by Grantor. The sale of a part of the Mortgaged Property
shall not exhaust the power of sale, but sales may be made from time to time
until the Secured Indebtedness is paid and performed in full.

                      (C)       Foreclosure Without Acceleration. If default is
made in the payment of any installment of the Secured Indebtedness, Beneficiary
may, at its option, at once or at any time thereafter while any matured
installment remains unpaid, without declaring the entire Secured Indebtedness
to be due and payable, orally or in writing direct the Trustee to enforce this
trust and to sell the Mortgaged Property subject to such unmatured indebtedness
and the assignments, liens, and security interests securing its payment, in the
same manner, on the same terms, at the same place and time and after having
given notice in the same manner, all as provided in the preceding provisions of
Subsection 6.1(B). After such sale, the Trustee shall make due





                                     13
<PAGE>   81
conveyance to the purchaser or purchasers. Sales made without maturing the
Secured Indebtedness may be made hereunder whenever there is a default in the
payment of any installment of the Secured Indebtedness without affecting in any
way the power of sale granted under this Subsection 6.1(C), the unmatured
balance of the Secured Indebtedness (except as to any proceeds of any sale
which Beneficiary may apply as a prepayment of the Secured Indebtedness) or the
assignments, liens and security interests securing payment of the Secured
Indebtedness.

                      (D)       Legal Proceedings. Beneficiary may or Trustee
may upon written request of Beneficiary, proceed by suit or suits, at law or in
equity, to enforce the payment and performance of the Secured Indebtedness in
accordance with the terms hereof or of the other Loan Documents, to foreclose
or otherwise enforce the assignments, liens, and security interests created or
evidenced by the other Loan Documents, or this Deed of Trust as against all, or
any part of, the Mortgaged Property, and to have all or any part of the
Mortgaged Property sold under the judgment or decree of a court of competent
jurisdiction.

                      (E)       Appointment of Receiver. To the extent
permitted by law, Beneficiary shall be entitled to the appointment of a
receiver or receivers of the Mortgaged Property, or any part thereof, and of
the Rents and Grantor hereby expressly consents to any such appointment.

                      (F)       Possession. To the extent permitted by law,
Beneficiary may enter upon the Land, take possession of the Mortgaged Property
and remove the Personal Property or any part thereof, with or without judicial
process, and, in connection therewith, without any responsibility or liability,
including, without limitation, liability for consequential damages of any kind
on the part of Beneficiary, and Beneficiary may take possession of any property
located on or in the Real Estate which is not a part of the Mortgaged Property
and hold or store such property at Grantor's expense.

                      (G)       Performance of Covenants. If Grantor or the
Obligated Parties have failed to keep or perform any covenant whatsoever
contained in the Loan Documents or in the Leases, Beneficiary may, but shall
not be obligated to, perform or attempt to perform said covenant, and any
payment made or expense incurred in the performance or attempted performance of
any such covenant shall be a part of the Secured Indebtedness, and Grantor
promises, upon demand, to pay to Beneficiary all sums so advanced by
Beneficiary, with interest at the highest default rate specified in the Term
Note from the date when paid by Beneficiary. No such payment by Beneficiary
shall constitute a waiver of any Event of Default.  In addition to the liens
and security interests hereof, Beneficiary shall be subrogated to all Liens
securing the payment of any debt, claim, tax, or assessment which Beneficiary
may pay.

                      (H)       Right to Make Repairs, Improvements. Should any
part of the Mortgaged Property come into the possession of Beneficiary after
the occurrence of an Event of Default, Beneficiary may use, operate, and/or
make repairs, alterations,





                                     14
<PAGE>   82
additions and improvements to the Mortgaged Property for the purpose of
preserving it or its value.  Grantor covenants to promptly reimburse and pay to
Beneficiary, at the address set forth at the beginning of this Deed of Trust or
at such other place as may be designated by Beneficiary in writing, the amount
of all reasonable expenses (including the cost of any insurance, taxes, or
other charges) incurred by Beneficiary in connection with its custody,
preservation, use or operation of the Mortgaged Property, together with
interest thereon from the date incurred by Beneficiary at the highest default
rate specified in the Term Note, and all such expenses, cost, taxes, interest,
and other charges shall be a part of the Secured Indebtedness. It is agreed,
however, that the risk of accidental loss or damage to the Mortgaged Property
is undertaken by Grantor, and, except for Beneficiary's willful misconduct or
gross negligence, Beneficiary shall have no liability whatsoever for decline in
value of the Mortgaged Property, or for failure to determine whether any
insurance ever in force is adequate as to amount or as to the risks insured.

                      (I)       Surrender of Insurance. Beneficiary may
surrender the insurance policies maintained pursuant to the terms hereof, or
any part thereof, and receive and apply the unearned premiums as a credit on
the Secured Indebtedness, and, in connection therewith, Grantor hereby appoints
Beneficiary (or any officer of Beneficiary), as the true and lawful agent and
attorney-in-fact for Grantor (with full powers of substitution), which power of
attorney shall be deemed to be a power coupled with an interest and therefore
irrevocable, to collect such premiums.

                      (J)       Collection of Personal Property. Beneficiary
may, in its own name or the name of Grantor, notify any or all parties
obligated on any of the Personal Property to make all payments due or to become
due thereon directly to Beneficiary, whereupon the power and authority of
Grantor to collect the same in the ordinary course of its business shall be
deemed to be immediately revoked and terminated. With or without such general
notification, Beneficiary may take or bring in Grantor's name or that of
Beneficiary all steps, actions, suits or proceedings deemed by Beneficiary
necessary or desirable to effect possession or collection of the Personal
Property, including sums due or paid thereon, may complete any contract or
agreement of Grantor in any way related to any of the Personal Property, may
make allowances or adjustments related to the Personal Property, may compromise
any claims related to the Personal Property, may issue credit in its own name
or the name of Grantor, may remove from Grantor's premises all documents,
instruments, records, files or other items relating to the Personal Property,
and Beneficiary may, without cost or expense to Beneficiary, use Grantor's
personnel, supplies and space to take possession of, administer, collect and
disclose of the Personal Property. Regardless of any provision hereof, however,
Beneficiary shall never be liable for its failure to collect or for its failure
to exercise diligence in the collection, possession, or any transaction
concerning, all or part of the Personal Property or sums due or paid thereon,
nor shall it be under any obligation whatsoever to anyone by virtue of this
Deed of Trust, except to account for the funds that it shall actually receive
hereunder.

<PAGE>   83
                      (K)       Issuance of Receipts; Endorsements; Power of
Attorney.  Issuance by Beneficiary of a receipt to any person, firm,
corporation or other entity obligated to pay any amounts to Grantor shall be a
full and complete release, discharge and acquittance to such person, firm,
corporation or other entity to the extent of any amount so paid to Beneficiary.
Beneficiary is hereby authorized and empowered on behalf of Grantor to endorse
the name of Grantor upon any check, draft, instrument, receipt, instruction or
other document or items, including, but not limited to, all items evidencing
payment upon any indebtedness of any person, firm, corporation or other entity
to Grantor coming into Beneficiary's possession, and to receive and apply the
proceeds therefrom in accordance with the terms hereof. Beneficiary is hereby
granted an irrevocable power of attorney, which is coupled with an interest, to
execute all checks, drafts, receipts, instruments, instructions or other
documents, agreements or items on behalf of Grantor, either before or after an
Event of Default as shall be deemed by Beneficiary to be necessary or
advisable, in the sole discretion of Beneficiary, to protect its security
interest in the Personal Property or the repayment of the Secured Indebtedness,
and Beneficiary shall not incur any liability in connection with or arising
from its exercise of such power of attorney.

                      (L)       Foreclosure of Personal Property with Real
Property.  Beneficiary may proceed under the Code as to all personal property
covered hereby, or, at Beneficiary's election, Beneficiary may proceed as to
both the real and personal property covered hereby in accordance with
Beneficiary's Rights in respect of real property, in which case the provisions
of the Code shall not apply.

                      (M)       Other Rights. Beneficiary shall have and may
exercise (i) the Rights of a secured party under the Code, (ii) any and all
other Rights which Beneficiary may have at law or in equity and (iii) all
Rights with respect to the Personal Property as provided in the Loan Documents.

                      (N)       Collect Rents. Beneficiary may terminate the
license granted to Grantor in Section 7.l hereof to collect the Rents, and,
without taking possession, in Beneficiary's own name, Beneficiary may demand,
collect, receive, sue for, attach and levy the Rents, and give proper receipts,
releases and acquittances therefor.

                      (O)       Manage Leases. Beneficiary may make, modify,
enforce, cancel or accept the surrender of any Lease, remove or evict any
Lessee, increase or reduce rents, decorate, clean and make repairs, and
otherwise do any act or incur any costs or expenses that Beneficiary shall deem
proper to protect the security hereof, as fully and to the same extent as
Grantor could do if in possession of the Mortgaged Property.

          Section 6.2.  Acts of Trustee; Prima Facie Evidence.  Grantor and
Beneficiary agree that, in any assignments, deeds, bills of sale, notices of
sale, or postings, given by Trustee or Beneficiary, any and all statements of
fact or other recitals therein made as to the identity of Beneficiary, or as to
the occurrence or existence of any Event of Default, or as to the acceleration
of the maturity of the Secured Indebtedness, or as to the request to sell,
posting of notice of sale, notice of sale, time, place, terms and





                                     16
<PAGE>   84
manner of sale and receipt, distribution and application of the money realized
therefrom, or as to the due and proper appointment of a substitute trustee and
without being limited by the foregoing, as to any other act or thing having
been duly done by Beneficiary or by Trustee, shall be taken by all courts of
law and equity as prima facie evidence that the said statements or recitals
state facts and are without further questions to be so accepted, and Grantor
does hereby ratify and confirm any and all acts that Trustee may lawfully do in
the premises by virtue hereof.

          Section 6.3.  Possession: Tenant at Sufferance. If the assignments,
liens, or security interests hereof shall be foreclosed or otherwise enforced
by a Trustee's sale, or by any other judicial or non-judicial action, then the
purchaser at any such sale shall receive, as an incident to his ownership,
immediate possession of that portion of the Mortgaged Property purchased, and
if Grantor or Grantor's Successors or Lessees shall hold possession of any of
said portion of the Mortgaged Property subsequent to such foreclosure, Grantor
and Grantor's Successors or Lessees in possession shall be considered as
tenants at sufferance of the purchaser at such foreclosure sale, and anyone
occupying the Mortgaged Property (or any part thereof) after demand made for
possession thereof shall be guilty of forcible detainer and shall be subject to
eviction and removal, forcible or otherwise, with or without process of law,
and all damages by reason thereof are hereby expressly waived.

          Section 6.4.  Application of Proceeds. All amounts received by
Beneficiary hereunder shall be applied as follows: FIRST, to the payment of all
reasonable expenses arising out of or in connection with the Mortgaged
Property, the foreclosure thereof, and the collection of the Secured
Indebtedness including, without limitation, the commissions, reasonable fees
and expenses of Beneficiary's attorneys, accountants, real estate brokers,
property managers, receivers, and of the Trustees; SECOND, to the Secured
Indebtedness; and THIRD, the balance, if any, remaining after the full and
final payment and performance of the Secured Indebtedness, to Grantor.

          Section 6.5.  Mortgage. This instrument shall be effective as a
mortgage as well as a deed of trust, and upon the occurrence of an Event of
Default may be foreclosed as to the Mortgaged Property in any manner permitted
by the laws of Texas. Any foreclosure suit may be brought by Trustee or
Beneficiary.  If a foreclosure hereunder is commenced by Trustee, Beneficiary
may, at any time before the sale, direct the Trustee to abandon the sale, and
may then institute suit for the collection of the Secured Indebtedness, and for
the foreclosure of enforcement of the assignments, liens, and security
interests hereof.  If Beneficiary should institute a suit for the collection of
the Secured Indebtedness, and for a foreclosure or enforcement of the
assignments, liens, and security interests hereof, it may, at any time before
the entry of a final judgment in said suit, dismiss the same, and require
Trustee to sell the Mortgaged Property, or any part thereof, in accordance with
the provisions of this Deed of Trust.

                         ASSIGNMENT OF LEASES AND RENTS

          Section 7.1. Grantor does hereby grant, transfer and assign unto
Beneficiary (A) the Leases, (B) any and all guaranties of payment or
performance of the obligations of any Lessee, and (C) the Rents; provided,
however, that Beneficiary hereby grants to Grantor a license to collect and
receive all Rents. Such license shall be revocable by notice from Beneficiary
to Grantor at any time after the occurrence and during the continuation of an
Event of Default.

          Section 7.2. No Liability on Beneficiary. Beneficiary shall not be
liable for any loss sustained by Grantor resulting from Beneficiary's failure
to let the Mortgaged Property, or any part thereof, after an Event of Default
or from any other act or omission of Beneficiary in managing the Mortgaged
Property, or any part thereof. Beneficiary shall not be obligated to perform or
discharge, any obligation, duty or liability under the Leases or under or by
reason of this Deed of Trust, and Grantor shall indemnify Beneficiary for, and
hold Beneficiary harmless from, any and all liability, loss or damage which may
or might be incurred under the Leases or under or by reason of this Deed of
Trust, and from any and all claims and demands whatsoever which may be asserted
against Beneficiary by reason of any alleged obligations or undertakings on its
part to perform or discharge any of the terms, covenants or agreements
contained in the Leases. Should Beneficiary incur any such liability under the
Leases or under or by reason of this Deed of Trust or in defense of any such
claims or demands, the amount thereof, including costs, expenses and reasonable
attorneys' fees shall be secured hereby and Grantor shall reimburse Beneficiary
therefor immediately upon demand, and upon the failure of Grantor to do so
Beneficiary may, at its option, declare the Secured Indebtedness immediately
due and payable. It is further understood that this Deed of Trust shall not
operate to place responsibility for the control, care, management or repair of
the Mortgaged Property upon Beneficiary, or for the carrying out of any of the
terms and conditions of the Leases; nor shall it operate to make Beneficiary
responsible or liable for any waste committed on the Mortgaged Property by the
Lessees or any other parties, or for any dangerous or defective condition of
the Mortgaged Property, or for any negligence in the management, upkeep, repair
or control of the Mortgaged Property, resulting in loss, injury or death to any
Lessee, licensee, employee or stranger.


                                  ARTICLE VIII

                               SECURITY AGREEMENT

          Section 8.1. Grant of Security Interest. Grantor hereby transfers,
assigns, delivers and grants a security interest in and right of set-off
against the Personal Property to Beneficiary as security for payment of the
Secured Indebtedness.

Section 8.2. Assignment of Non-Code Personal Property. To the extent that any





                                     18
<PAGE>   86
of the Personal Property is not subject to the Code, Grantor hereby assigns to
Beneficiary all of Grantor's right, title, and interest in and to the Personal
Property to secure the Secured Indebtedness, together with the right of set-
off with regard to such Personal Property (or any part hereof). Release of the
lien of this Deed of Trust shall automatically terminate this assignment.


                                   ARTICLE IX

                                 MISCELLANEOUS

          Section 9. l. Release of this Deed of Trust.  If the Secured
Indebtedness is paid and performed in full in accordance with the terms of the
instruments evidencing the Secured Indebtedness, and if Grantor shall well and
truly perform all of Grantor's covenants contained herein, then this conveyance
shall become null and void and be released at Grantor's request and expense;
otherwise, it shall remain in full force and effect, provided that no release
hereof shall impair Grantor's warranties and indemnities contained herein.

          Section 9.2. Successors. If Grantor, or any of Grantor's Successors,
conveys its interest in any of the Mortgaged Property to any other party, then
Beneficiary may, without notice to Grantor, or its successors and assigns, deal
with any owner of any part of the Mortgaged Property with reference to this
Deed of Trust and the Secured Indebtedness, either by way of forbearance on the
part of Beneficiary, or extension of time of payment of the Secured
Indebtedness, or release of all or any part of the Mortgaged Property, or any
other property securing payment of the Secured Indebtedness, without in any way
modifying or affecting Beneficiary's Rights and Liens hereunder or the
liability of Grantor, or any other party liable for payment of the Secured
Indebtedness, in whole or in part.

          Section 9.3. Marshaling. Grantor hereby waives all Rights of
marshaling in the event of any foreclosure of the Liens hereby created.

          Section 9.4. Reserve for Taxes and Insurance. At the request of
Beneficiary after the occurrence and during the continuance of a default or an
Event of Default, Grantor shall create a fund or reserve for the payment of all
ground rentals, insurance premiums, taxes, and assessments against the
Mortgaged Property by paying to Beneficiary a sum equal to the rentals payable
by Grantor to any lessor of the Mortgaged Property, or any part thereof, plus
the premiums that will next become due and payable on the hazard insurance
policies covering the Mortgaged Property, or any part thereof, plus taxes and
assessments next due on the Mortgaged Property, or any part thereof, as
estimated by Beneficiary, less all sums paid previously to Beneficiary
therefor, divided by the number of installments of principal and/or interest to
elapse before one month prior to the date when such ground rentals, premiums,
taxes, and assessments will become delinquent, such sums to be held by
Beneficiary, without interest, for the purposes of paying such ground rentals,
premiums, taxes, and





                                     19
<PAGE>   87
assessments. Beneficiary shall have the right (but not the obligation) to apply
such sums to the payment of such ground rentals, premiums, taxes and
assessments. Any excess reserve shall, at the discretion of Beneficiary, be
credited by Beneficiary on subsequent payments to be made on the Secured
Indebtedness by Grantor, and any deficiency shall be paid by Grantor to
Beneficiary on or before the date when such ground rentals, premiums, taxes,
and assessment;, shall have become delinquent.

          Section 9.5. Condemnation. Beneficiary shall be entitled to receive
any and all sums which may be awarded or become payable to Grantor for the
condemnation of any of the Mortgaged Property for public or quasi-public use,
or by virtue of private sale in lieu thereof, and any sums which may be awarded
or become payable to Grantor for damages caused by public works or construction
on or near the Mortgaged Property. Grantor shall give immediate written notice
to Beneficiary of any such condemnation proceeding affecting the Mortgaged
Property, and shall afford Beneficiary an opportunity to participate in any
proceeding or settlement of awards with respect thereto. All such sums are
hereby assigned to Beneficiary, and Grantor shall, upon request of Beneficiary,
make, execute, acknowledge, and deliver any and all additional assignments and
documents as may be necessary from time to time to enable Beneficiary to
collect and receipt for any such sums.  Beneficiary shall not be, under any
circumstances, liable or responsible for failure to collect, or exercise
diligence in the collection of, any of such sums.  Any sums so collected shall
be applied by Beneficiary, first, to the expenses, if any, of collection, and
then in accordance with Section 6.4 hereof.  Notwithstanding the foregoing, if,
after such condemnation or private sale in lieu thereof, Beneficiary determines
in its reasonable judgment that the remainder of the Mortgaged Property can be
restored in such a manner as to preserve substantially the economic value
thereof and no Event of Default has occurred and is continuing, upon request of
Grantor such sums so held by Beneficiary shall be made available for such
restoration and disbursed by Beneficiary during the course of such restoration
under safeguards reasonably satisfactory to Beneficiary. Any sums remaining
after completion of restoration shall be applied in accordance with Section
6.4.

          Section 9.6. Insurance Proceeds. Beneficiary shall receive the
proceeds of any and all insurance that may become payable with respect to any
of the Mortgaged Property, and so long as no Event of Default has occurred and
is continuing and such proceeds (together with any other amounts deposited by
Grantor with Beneficiary) are sufficient to rebuild and restore the
Improvements, shall make such proceeds available to rebuild or restore the
Improvements or, if an Event of Default has occurred and is continuing or if
such proceeds (together with any other amounts deposited by Grantor with
Beneficiary) are not sufficient to rebuild and restore the Improvements,
Beneficiary may apply the same to the Secured Indebtedness in the order and
manner set forth in Section 6.4 hereof, whether then matured or to mature in
the future, and prior to such application, may deduct therefrom any expenses
incurred in connection with the collection or handling of such proceeds, it
being understood that Beneficiary shall not be, under any circumstances,
liable, or responsible for failure to collect, or exercise diligence in the
collection of, any of such proceeds.

          Section 9.7. Subrogation. It is understood and agreed that the funds
loaned to any of the Obligated Parties pursuant to the Loan Agreement, to the
extent that the same are utilized to pay or renew or extend any indebtedness of
the Obligated Parties, or any other indebtedness, or take up or release any
outstanding Liens against the Mortgaged Property, or any portion thereof, have
been advanced by Beneficiary at Grantor's request and at the request of the
Obligated Parties and upon their representation that such amounts are due and
payable. Beneficiary shall be subrogated to any and all Rights and Liens owned
or claimed by any owner or beneficiary of said outstanding Rights and Liens,
however remote, regardless of whether said Rights and Liens are acquired by
assignment or are released by the beneficiary thereof upon payment.

          Section 9.8. Illegality. If any provision of this Deed of Trust is
held to be illegal, invalid, or unenforceable under present or future laws
effective during the term of this Deed of Trust, the legality, validity, and
enforceability of the remaining provisions of this Deed of Trust shall not be
affected thereby, and in lieu of each such illegal, invalid or unenforceable
provision there shall be added automatically as a part of this Deed of Trust a
provision as similar in terms to such illegal, invalid, or unenforceable
provision as may be possible and be legal, valid, and enforceable. If the
Rights and Liens created by this Deed of Trust shall be invalid or
unenforceable as to any part of the Secured Indebtedness, then the unsecured
portion of the Secured Indebtedness shall be completely paid prior to the
payment of the remaining and secured portion of the Secured Indebtedness, and
all payments made on the Secured Indebtedness shall be considered to have been
paid on and applied first to the complete payment of the unsecured portion of
the Secured Indebtedness.

          Section 9.9. Maximum Interest Rate. Notwithstanding anything
contained in this Deed of Trust or in any of the Loan Documents to the
contrary, Beneficiary shall never be deemed to have contracted for or be
entitled to receive, collect or apply as interest on the Secured Indebtedness,
any amount in excess of the amount permitted and calculated at the highest
lawful rate, and, in the event Beneficiary ever receives, collects or applies
as interest any amount in excess of the amount permitted and calculated at the
highest lawful rate, such amount which would be excessive interest shall be
applied to the reduction of the unpaid principal balance of the Secured
Indebtedness, and, if the principal balance of the Secured Indebtedness is paid
in full, any remaining excess shall forthwith be paid to Grantor. In
determining whether or not the interest paid or payable under any specific
contingency exceeds the amount of interest permitted and calculated at the
highest lawful rate, Grantor and Beneficiary shall, to the maximum extent
permitted under applicable law, (A) characterize any non-principal payment
(other than payments which are expressly designated as interest payments
hereunder) as an expense, fee, or premium, rather than as interest, (B) exclude
voluntary prepayments and the effect thereof, and (C) spread the total amount
of interest throughout the entire contemplated term of the Secured
Indebtedness.

          Section 9.10. Obligations Binding Upon Grantor's Successors. This
Deed of Trust is binding upon Grantor and Grantor's Successors, and shall inure
to the benefit





                                     21

of Beneficiary, and its successors and assigns, and the provisions hereof shall
likewise be covenants running with the land. The duties, covenants, conditions,
obligations and warranties of Grantor in this Deed of Trust shall be joint and
several obligations of Grantor and Grantor's Successors.

construction upon, the Mortgaged Property, or any part thereof, and agrees to
assume liability for, and to indemnify and hold Beneficiary harmless from and
against, any and all losses, damages, claims, costs, penalties, causes of
action, liabilities and expenses, including court costs and attorneys' fees,
howsoever arising (including, without limitation, for injuries to or deaths of
persons and damage to property), from or incident to such ownership of the
Mortgaged Property and development, use, possession, maintenance, management,
and construction.

          Section 9.14. Vendor's Lien. If all or any portion of the Secured
Indebtedness has been advanced for the purpose of paying the purchase price for
all or a part of the Mortgaged Property, then: (A) Beneficiary shall have, and
is hereby granted, a vendor's lien on the Mortgaged Property to further secure
the Secured Indebtedness; and (B) Beneficiary shall be subrogated to all
rights, titles, interests, liens, and security interests owned or claimed by
the holder of any indebtedness which has been directly or indirectly discharged
or paid from the proceeds of the Secured Indebtedness.

                         CONTINUING GUARANTY AGREEMENT
   [Indebtedness of DXP Acquisition, Inc. d/b/a Strategic Acquisition, Inc. -
                      Pelican State Supply Company, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of DXP ACQUISITION,
INC. D/B/A STRATEGIC ACQUISITION, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time (the "Borrower Loan Agreement"); (ii) any document executed
in connection with or as security for payment of the Obligations or any
renewal, extension, or modification thereof; and (iii) all costs, attorneys'
fees, and other expenses incurred by Lender by reason of any default by
Borrower under any of the foregoing (all of the foregoing are hereinafter
referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal




                                      1
<PAGE>   2
disability; acknowledges that its liability hereunder shall be cumulative and
in addition to any other liability or obligation to Lender, whether the same is
incurred through the execution of a note, a similar guaranty, through
endorsement, or otherwise; and acknowledges that neither Lender nor any
officer, employee, agent, attorney or other representative of Lender has made
any representation, warranty or statement to Guarantor to induce it to execute
this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or





                                       2
<PAGE>   3
any part thereof that diligent inquiry would reveal.  Guarantor hereby agrees
that Lender shall have no duty to advise Guarantor of information known to
Lender regarding such condition or any such circumstances.  Guarantor is not
relying on the financial condition of Borrower or the value of any collateral
for the Obligations as an inducement to enter into this Guaranty.  If Lender,
in its sole discretion, undertakes at any time or from time to time to provide
any such information to Guarantor, Lender shall be under no obligation (i) to
undertake any investigation not a part of its regular business routine, (ii) to
disclose any information which, pursuant to accepted or reasonable commercial
finance practices, Lender wishes to maintain confidential, or (iii) to make any
other or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal





                                       3
<PAGE>   4
Rate, shall be without binding force or effect, at law or in equity, to the
extent only of the excess of interest over such Maximum Legal Rate.  In the
event any interest is charged or collected in excess of the Maximum Legal Rate
("Excess"), Guarantor acknowledges and stipulates that any such charge or
collection shall be the result of an accident and bona fide error, and such
Excess shall be, first, applied to reduce the Obligations; and second, returned
to Guarantor, it being the intention of the parties hereto not to enter at any
time into a usurious or otherwise illegal relationship.  Guarantor recognizes
that, with fluctuations in the applicable rate on the Obligations and the
Maximum Legal Rate, such an unintentional result could inadvertently occur.  By
the execution of this Guaranty, Guarantor covenants that Guarantor shall not
seek or pursue any other remedy, legal or equitable, against Lender, based in
whole or in part upon the contracting, charging or receiving of any interest in
excess of the maximum authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees (i) that Guarantor's contingent
obligations under this Guaranty constitute "Obligations", as such term is
defined in that certain Loan and Security Agreement, dated as of May 29, 1997,
executed by Lender and Guarantor, as renewed, extended, modified, and restated
from time to time (the "Guarantor Loan Agreement"), and (ii) that the
occurrence of a "Default" or "Event of Default" pursuant to the provisions of
the Borrower Loan Agreement shall also constitute a "Default" or an "Event of
Default", as the case may be, pursuant to the provisions of the Guarantor Loan
Agreement.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR

AGREEMENTS BETWEEN THE PARTIES.

                         CONTINUING GUARANTY AGREEMENT
   [Indebtedness of DXP Acquisition, Inc. d/b/a Strategic Acquisition, Inc. -
                             DXP Enterprises, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of DXP ACQUISITION,
INC. D/B/A STRATEGIC ACQUISITION, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time; (ii) any document executed in connection with or as security
for payment of the Obligations or any renewal, extension, or modification
thereof; and (iii) all costs, attorneys' fees, and other expenses incurred by
Lender by reason of any default by Borrower under any of the foregoing (all of
the foregoing are hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal



                                      1

disability; acknowledges that its liability hereunder shall be cumulative and
in addition to any other liability or obligation to Lender, whether the same is
incurred through the execution of a note, a similar guaranty, through
endorsement, or otherwise; and acknowledges that neither Lender nor any
officer, employee, agent, attorney or other representative of Lender has made
any representation, warranty or statement to Guarantor to induce it to execute
this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or





                                       2
<PAGE>   3
any part thereof that diligent inquiry would reveal.  Guarantor hereby agrees
that Lender shall have no duty to advise Guarantor of information known to
Lender regarding such condition or any such circumstances.  Guarantor is not
relying on the financial condition of Borrower or the value of any collateral
for the Obligations as an inducement to enter into this Guaranty.  If Lender,
in its sole discretion, undertakes at any time or from time to time to provide
any such information to Guarantor, Lender shall be under no obligation (i) to
undertake any investigation not a part of its regular business routine, (ii) to
disclose any information which, pursuant to accepted or reasonable commercial
finance practices, Lender wishes to maintain confidential, or (iii) to make any
other or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal





                                       3
<PAGE>   4
Rate, shall be without binding force or effect, at law or in equity, to the
extent only of the excess of interest over such Maximum Legal Rate.  In the
event any interest is charged or collected in excess of the Maximum Legal Rate
("Excess"), Guarantor acknowledges and stipulates that any such charge or
collection shall be the result of an accident and bona fide error, and such
Excess shall be, first, applied to reduce the Obligations; and second, returned
to Guarantor, it being the intention of the parties hereto not to enter at any
time into a usurious or otherwise illegal relationship.  Guarantor recognizes
that, with fluctuations in the applicable rate on the Obligations and the
Maximum Legal Rate, such an unintentional result could inadvertently occur.  By
the execution of this Guaranty, Guarantor covenants that Guarantor shall not
seek or pursue any other remedy, legal or equitable, against Lender, based in
whole or in part upon the contracting, charging or receiving of any interest in
excess of the maximum authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

                         CONTINUING GUARANTY AGREEMENT
             [Indebtedness of DXP Acquisition, Inc. d/b/a Strategic
                  Acquisition, Inc. - Sepco Industries, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of DXP ACQUISITION,
INC. D/B/A STRATEGIC ACQUISITION, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time (the "Borrower Loan Agreement"); (ii) any document executed
in connection with or as security for payment of the Obligations or any
renewal, extension, or modification thereof; and (iii) all costs, attorneys'
fees, and other expenses incurred by Lender by reason of any default by
Borrower under any of the foregoing (all of the foregoing are hereinafter
referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other




                                      1
<PAGE>   2
liability or obligation to Lender, whether the same is incurred through the
execution of a note, a similar guaranty, through endorsement, or otherwise; and
acknowledges that neither Lender nor any officer, employee, agent, attorney or
other representative of Lender has made any representation, warranty or
statement to Guarantor to induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no





                                       2
<PAGE>   3
duty to advise Guarantor of information known to Lender regarding such
condition or any such circumstances.  Guarantor is not relying on the financial
condition of Borrower or the value of any collateral for the Obligations as an
inducement to enter into this Guaranty.  If Lender, in its sole discretion,
undertakes at any time or from time to time to provide any such information to
Guarantor, Lender shall be under no obligation (i) to undertake any
investigation not a part of its regular business routine, (ii) to disclose any
information which, pursuant to accepted or reasonable commercial finance
practices, Lender wishes to maintain confidential, or (iii) to make any other
or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of





                                       3
<PAGE>   4
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the Maximum Legal Rate ("Excess"), Guarantor
acknowledges and stipulates that any such charge or collection shall be the
result of an accident and bona fide error, and such Excess shall be, first,
applied to reduce the Obligations; and second, returned to Guarantor, it being
the intention of the parties hereto not to enter at any time into a usurious or
otherwise illegal relationship.  Guarantor recognizes that, with fluctuations
in the applicable rate on the Obligations and the Maximum Legal Rate, such an
unintentional result could inadvertently occur.  By the execution of this
Guaranty, Guarantor covenants that Guarantor shall not seek or pursue any other
remedy, legal or equitable, against Lender, based in whole or in part upon the
contracting, charging or receiving of any interest in excess of the maximum
authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees (i) that Guarantor's contingent
obligations under this Guaranty constitute "Obligations", as such term is
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, executed by Lender and Guarantor, as
renewed, extended, modified, and restated from time to time (the "Guarantor
Loan Agreement"), and (ii) that the occurrence of a "Default" or an "Event of
Default" pursuant to the provisions of the Borrower Loan Agreement shall also
constitute a "Default" or an "Event of Default", as the case may be, pursuant
to the provisions of the Guarantor Loan Agreement.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

                         CONTINUING GUARANTY AGREEMENT
             [Indebtedness of DXP Acquisition, Inc. d/b/a Strategic
                    Acquisition, Inc. - American MRO, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of DXP ACQUISITION,
INC. D/B/A STRATEGIC ACQUISITION, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time (the "Borrower Loan Agreement"); (ii) any document executed
in connection with or as security for payment of the Obligations or any
renewal, extension, or modification thereof; and (iii) all costs, attorneys'
fees, and other expenses incurred by Lender by reason of any default by
Borrower under any of the foregoing (all of the foregoing are hereinafter
referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other




                                      1
<PAGE>   2
liability or obligation to Lender, whether the same is incurred through the
execution of a note, a similar guaranty, through endorsement, or otherwise; and
acknowledges that neither Lender nor any officer, employee, agent, attorney or
other representative of Lender has made any representation, warranty or
statement to Guarantor to induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no





                                       2
<PAGE>   3
duty to advise Guarantor of information known to Lender regarding such
condition or any such circumstances.  Guarantor is not relying on the financial
condition of Borrower or the value of any collateral for the Obligations as an
inducement to enter into this Guaranty.  If Lender, in its sole discretion,
undertakes at any time or from time to time to provide any such information to
Guarantor, Lender shall be under no obligation (i) to undertake any
investigation not a part of its regular business routine, (ii) to disclose any
information which, pursuant to accepted or reasonable commercial finance
practices, Lender wishes to maintain confidential, or (iii) to make any other
or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of





                                       3
<PAGE>   4
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the Maximum Legal Rate ("Excess"), Guarantor
acknowledges and stipulates that any such charge or collection shall be the
result of an accident and bona fide error, and such Excess shall be, first,
applied to reduce the Obligations; and second, returned to Guarantor, it being
the intention of the parties hereto not to enter at any time into a usurious or
otherwise illegal relationship.  Guarantor recognizes that, with fluctuations
in the applicable rate on the Obligations and the Maximum Legal Rate, such an
unintentional result could inadvertently occur.  By the execution of this
Guaranty, Guarantor covenants that Guarantor shall not seek or pursue any other
remedy, legal or equitable, against Lender, based in whole or in part upon the
contracting, charging or receiving of any interest in excess of the maximum
authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees (i) that Guarantor's contingent
obligations under this Guaranty constitute "Obligations", as such term is
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, executed by Lender and Sepco Industries,
Inc., as renewed, extended, modified, and restated from time to time (the
"Guarantor Loan Agreement"), and (ii) that the occurrence of a "Default" or
"Event of Default" pursuant to the provisions of the Borrower Loan Agreement
shall also constitute a "Default" or an "Event of Default", as the case may be,
pursuant to the provisions of the Guarantor Loan Agreement.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF

AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS

JURISDICTION OR VENUE.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other



                                      1
<PAGE>   2
liability or obligation to Lender, whether the same is incurred through the
execution of a note, a similar guaranty, through endorsement, or otherwise; and
acknowledges that neither Lender nor any officer, employee, agent, attorney or
other representative of Lender has made any representation, warranty or
statement to Guarantor to induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no





                                       2
<PAGE>   3
duty to advise Guarantor of information known to Lender regarding such
condition or any such circumstances.  Guarantor is not relying on the financial
condition of Borrower or the value of any collateral for the Obligations as an
inducement to enter into this Guaranty.  If Lender, in its sole discretion,
undertakes at any time or from time to time to provide any such information to
Guarantor, Lender shall be under no obligation (i) to undertake any
investigation not a part of its regular business routine, (ii) to disclose any
information which, pursuant to accepted or reasonable commercial finance
practices, Lender wishes to maintain confidential, or (iii) to make any other
or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of





                                       3
<PAGE>   4
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the Maximum Legal Rate ("Excess"), Guarantor
acknowledges and stipulates that any such charge or collection shall be the
result of an accident and bona fide error, and such Excess shall be, first,
applied to reduce the Obligations; and second, returned to Guarantor, it being
the intention of the parties hereto not to enter at any time into a usurious or
otherwise illegal relationship.  Guarantor recognizes that, with fluctuations
in the applicable rate on the Obligations and the Maximum Legal Rate, such an
unintentional result could inadvertently occur.  By the execution of this
Guaranty, Guarantor covenants that Guarantor shall not seek or pursue any other
remedy, legal or equitable, against Lender, based in whole or in part upon the
contracting, charging or receiving of any interest in excess of the maximum
authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees (i) that Guarantor's contingent
obligations under this Guaranty constitute "Obligations", as such term is
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, executed by Lender and Sepco Industries,
Inc., as renewed, extended, modified, and restated from time to time (the
"Guarantor Loan Agreement"), and (ii) that the occurrence of a "Default" or
"Event of Default" pursuant to the provisions of the Borrower Loan Agreement
shall also constitute a "Default" or "Event of Default", as the case may be,
pursuant to the provisions of the Guarantor Loan Agreement.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.





                                       4

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.
   

       Executed on June 16, 1997, but effective for all purposes as of

                         CONTINUING GUARANTY AGREEMENT
                 [Indebtedness of Sepco Industries, Inc. - DXP
              Acquisition, Inc. d/b/a Strategic Acquisition, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of SEPCO INDUSTRIES,
INC., a Texas corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, between Lender and Borrower, as renewed,
extended, modified or restated from time to time; (ii) any document executed in
connection with or as security for payment of the Obligations or any renewal,
extension, or modification thereof; and (iii) all costs, attorneys' fees, and
other expenses incurred by Lender by reason of any default by Borrower under
any of the foregoing (all of the foregoing are hereinafter referred to as the
"Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in

                        CONTINUING GUARANTY AGREEMENT
                   [Indebtedness of American MRO, Inc. - DXP
              Acquisition, Inc. d/b/a Strategic Acquisition, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of AMERICAN MRO,
INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, between Lender and Sepco Industries,
Inc., as renewed, extended, modified or restated from time to time; (ii) any
document executed in connection with or as security for payment of the
Obligations or any renewal, extension, or modification thereof; and (iii) all
costs, attorneys' fees, and other expenses incurred by Lender by reason of any
default by Borrower under any of the foregoing (all of the foregoing are
hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED

United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT THE FINAL AGREEMENT BETWEEN THE

                         CONTINUING GUARANTY AGREEMENT
             [Indebtedness of Pelican State Supply Company, Inc. -
            DXP Acquisition, Inc. d/b/a Strategic Acquisition, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of PELICAN STATE
SUPPLY COMPANY, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated as of May 29, 1997,
between Lender and Borrower, as renewed, extended, modified or restated from
time to time; (ii) any document executed in connection with or as security for
payment of the Obligations or any renewal, extension, or modification thereof;
and (iii) all costs, attorneys' fees, and other expenses incurred by Lender by
reason of any default by Borrower under any of the foregoing (all of the
foregoing are hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other




                                      1
<PAGE>   2
liability or obligation to Lender, whether the same is incurred through the
execution of a note, a similar guaranty, through endorsement, or otherwise; and
acknowledges that neither Lender nor any officer, employee, agent, attorney or
other representative of Lender has made any representation, warranty or
statement to Guarantor to induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no





                                       2
<PAGE>   3
duty to advise Guarantor of information known to Lender regarding such
condition or any such circumstances.  Guarantor is not relying on the financial
condition of Borrower or the value of any collateral for the Obligations as an
inducement to enter into this Guaranty.  If Lender, in its sole discretion,
undertakes at any time or from time to time to provide any such information to
Guarantor, Lender shall be under no obligation (i) to undertake any
investigation not a part of its regular business routine, (ii) to disclose any
information which, pursuant to accepted or reasonable commercial finance
practices, Lender wishes to maintain confidential, or (iii) to make any other
or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of





                                       3
<PAGE>   4
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the Maximum Legal Rate ("Excess"), Guarantor
acknowledges and stipulates that any such charge or collection shall be the
result of an accident and bona fide error, and such Excess shall be, first,
applied to reduce the Obligations; and second, returned to Guarantor, it being
the intention of the parties hereto not to enter at any time into a usurious or
otherwise illegal relationship.  Guarantor recognizes that, with fluctuations
in the applicable rate on the Obligations and the Maximum Legal Rate, such an
unintentional result could inadvertently occur.  By the execution of this
Guaranty, Guarantor covenants that Guarantor shall not seek or pursue any other
remedy, legal or equitable, against Lender, based in whole or in part upon the
contracting, charging or receiving of any interest in excess of the maximum
authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT

this Agreement, Lender agrees to make Revolving Credit Loans to Borrower from
time to time, in amounts determined by Lender in its sole discretion, up to a
maximum principal amount at any time outstanding equal to the Borrowing Base at
such time.  If the unpaid balance of the Revolving Credit Loans should exceed
the Borrowing Base or any other limitation set forth in this Agreement, such
Revolving Credit Loans shall nevertheless constitute Obligations that are





LOAN AND SECURITY AGREEMENT - Page 13
<PAGE>   14
secured by the Collateral and entitled to all benefits thereof.  Insofar as
Borrower may request and Lender may be willing in its sole and absolute
discretion to make Revolving Credit Loans to Borrower at a time when the unpaid
balance of Revolving Credit Loans exceeds, or would exceed with the making of
any such Revolving Credit Loan, the Borrowing Base (any such Loan or Loans
being herein referred to individually as an "Overadvance" and collectively as
"Overadvances"), Lender shall enter such Overadvances as debits in the Loan
Account.  All Overadvances shall be payable ON DEMAND, shall be secured by the
Collateral and shall bear interest as provided herein for Revolving Credit
Loans generally.  The Revolving Credit Loans shall be used solely for the
satisfaction of existing Indebtedness of Borrower to and for Borrower's general
operating capital needs to the extent not inconsistent with the provisions of
this Agreement.

       A request for a Revolving Credit Loan shall be made or shall be deemed
to be made, in the following manner:  (i) Borrower may give Lender notice of
its intention to borrow, in which notice Borrower shall specify the amount of
the proposed borrowing and the proposed borrowing date (which notice shall be
in the form of a Eurodollar Borrowing Notice pursuant to Section 3.7(A) hereof
if Borrower intends to borrow a Eurodollar Loan); (ii) the becoming due of any
amount required to be paid under this Agreement as interest shall be deemed
irrevocably to be a request for a Revolving Credit Loan on the due date in the
amount required to pay such interest; (iii) the becoming due of any amount
required to be paid under this Agreement as principal shall be deemed
irrevocably to be a request for a Revolving Credit Loan on the due date for the
amount required to pay such principal; (iv) any payment made by Lender pursuant
to a Letter of Credit or LC Guaranty which is not immediately reimbursed by
Borrower shall be deemed irrevocably to be a request for a Revolving Credit
Loan on the date of such payment by Lender; and (v) the becoming due of any
other Obligations shall be deemed irrevocably to be a request for a Revolving
Credit Loan on the due date in the amount then so due.

       2.2.   All Loans to Constitute One Obligation.  All Loans shall
constitute one general obligation of Borrower, and shall be secured by Lender's
security interest in and Lien upon all of the Collateral, and by all other
security interests and Liens heretofore, now or at any time or times hereafter
granted by Borrower to Lender.

       2.3.   Loan Account.  Lender shall enter all Loans as debits to the Loan
Account and shall also record in the Loan Account all payments made by Borrower
on any Obligations and all proceeds of Collateral which are finally paid to
Lender, and may record therein, in accordance with customary accounting
practice, all charges and expenses properly chargeable to Borrower and any
other Obligation.

       2.4    Reimbursement Obligations.  If Lender shall pay any amount under
a Letter of Credit or LC Guaranty, then Borrower shall automatically become
obligated to immediately reimburse such amount to Lender, together with
interest from and after the date Lender makes such payment under such Letter of
Credit or LC Guaranty until payment in full to Lender by Borrower of Borrower's
reimbursement obligation which shall accrue at the applicable per annum rate of
interest then applicable for Revolving Credit Loans.





LOAN AND SECURITY AGREEMENT - Page 14

SECTION 3.    INTEREST, FEES, TERM AND REPAYMENT

       3.1.   Interest and Charges.

              (A)    Interest shall accrue on the principal amount of the
Revolving Credit Loans outstanding at the end of each day at the following
rates per annum (individually called, as applicable, an "Applicable Annual
Rate"):  (i) Eurodollar Loans shall bear interest at a rate per annum equal to
2.00% above the Eurodollar Base Rate for the Eurodollar Interest Period
applicable thereto and (ii) all other Revolving Credit Loans shall bear
interest at a rate per annum equal to .50% above the Base Rate.  Revolving
Credit Loans shall bear interest at a rate per annum equal to .50% above the
Base Rate unless the Borrower provides a Eurodollar Borrowing Notice to the
Lender in accordance with Section 3.7(A) irrevocably electing that all or a
portion of the Revolving Credit Loans are to bear interest at a Eurodollar Base
Rate.  Each Revolving Credit Loan that is not a Eurodollar Loan shall be
increased or decreased, as the case may be, by an amount equal to any increase
or decrease in the Base Rate, with such adjustments to be effective as of the
opening of business on the day that any such change in the Base Rate becomes
effective.  The Base Rate in effect on the date hereof shall be the Base Rate
effective as of the opening of business on the date hereof, but if this
Agreement is executed on a day that is not a Business Day, the Base Rate in
effect on the date hereof shall be the Base Rate effective as of the opening of
business on the last Business Day immediately preceding the date hereof.
Interest shall be calculated on a daily basis (computed on the actual number of
days elapsed over a year of 360 days), commencing on the date hereof, and shall
be payable monthly, in arrears, on the first day of each month; provided,
however, that interest at the Maximum Legal Rate shall be computed on the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be.  Upon and after the occurrence of an Event of Default, and during the
continuation thereof, the principal amount of the Obligations shall bear
interest at the lesser of (i) the Maximum Legal Rate or (ii) a fluctuating rate
per annum, calculated daily (computed on the actual days elapsed over a year of
360 days), equal to 4.0% above the Applicable Annual Rate or other applicable
rate of interest (the "Default Rate").

              (B)    Notwithstanding the foregoing or any other provision in
this Agreement, (i) if at any time the amount of interest computed on the basis
of the Applicable Annual Rate or the Default Rate would exceed the amount of
such interest computed upon the basis of the maximum rate of interest permitted
by applicable state or federal law in effect from time to time hereafter (the
"Maximum Legal Rate"), the interest payable under this Agreement shall be
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Applicable Annual Rate or Default Rate, as applicable, shall not reduce
such interest thereafter payable hereunder below the amount computed on the
basis of the Maximum Legal Rate until the aggregate amount of such interest
accrued and payable under this Agreement equals the total amount of interest
which would have accrued if such interest had been at all times computed solely
on the basis of the Applicable Annual Rate or Default Rate, as applicable; and
(ii) unless preempted by federal law, the Applicable Annual Rate or Default
Rate, as applicable, from time to time in effect hereunder may not exceed the
"indicated ceiling rate" from time to time in effect under Tex. Rev. Civ. Stat.
Ann. art 5069-1.04(c) (Vernon 1987).





LOAN AND SECURITY AGREEMENT - Page 15
<PAGE>   16
              (C)    No agreements, conditions, provisions or stipulations
contained in this Agreement or any other instrument, document or agreement
between Borrower and Lender or default of Borrower, or the exercise by Lender
of the right to accelerate the payment of the maturity of principal and
interest, or to exercise any option whatsoever contained in this Agreement or
any other agreement between Borrower and Lender, or the arising of any
contingency whatsoever, shall entitle Lender to contract for, charge, or
receive, in any event, interest exceeding the Maximum Legal Rate.  In no event
shall Borrower be obligated to pay interest exceeding such Maximum Legal Rate
and all agreements, conditions or stipulations, if any, which may in any event
or contingency whatsoever operate to bind, obligate or compel Borrower to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is contracted
for, charged or received in excess of the Maximum Legal Rate ("Excess"),
Borrower acknowledges and stipulates that any such contract, charge, or receipt
shall be the result of an accident and bona fide error, and that any Excess
received by Lender shall be applied, first, to reduce the principal then unpaid
hereunder; second, to reduce the other Obligations; and third, returned to
Borrower, it being the intention of the parties hereto not to enter at any time
into a usurious or otherwise illegal relationship.  Borrower recognizes that,
with fluctuations in the Base Rate, the Eurodollar Base Rate and the Maximum
Legal Rate, such a result could inadvertently occur.  By the execution of this
Agreement, Borrower covenants that (i) the credit or return of any Excess shall
constitute the acceptance by Borrower of such Excess, and (ii) Borrower shall
not seek or pursue any other remedy, legal or equitable, against Lender, based
in whole or in part upon contracting for, charging or receiving of any interest
in excess of the maximum authorized by applicable law.  For the purpose of
determining whether or not any Excess has been contracted for, charged or
received by Lender, all interest at any time contracted for, charged or
received by Lender in connection with this Agreement shall be amortized,
prorated, allocated and spread in equal parts during the entire term of this
Agreement.

              (D)    The provisions of Section 3.1(C) shall be deemed to be
incorporated into every document or communication relating to the Obligations
which sets forth or prescribes any account, right or claim or alleged account,
right or claim of Lender with respect to Borrower (or any other obligor in
respect of Obligations), whether or not any provision of Section 3.1 is
referred to therein.  All such documents and communications and all figures set
forth therein shall, for the sole purpose of computing the extent of the
Obligations and obligations of the Borrower (or other obligor) asserted by
Lender thereunder, be automatically recomputed by Borrower or obligor, and by
any court considering the same, to give effect to the adjustments or credits
required by Section 3.1(C).

              (E)    If the applicable state or federal law is amended in the
future to allow a greater rate of interest to be charged under this Agreement
or the Other Agreements than is presently allowed by applicable state or
federal law, then the limitation of interest hereunder shall be increased to
the maximum rate of interest allowed by applicable state or federal law as
amended, which increase shall be effective hereunder on the effective date of
such amendment, and all interest charges owing to Lender by reason thereof
shall be payable upon demand.





LOAN AND SECURITY AGREEMENT - Page 16
<PAGE>   17
              (F)    For the purpose of computing interest hereunder, all items
of payment received by Lender shall be deemed applied by Lender on account of
the Obligations (subject to final payment of such items) one (1) Business Day
after receipt by Lender of such items in Lender's account located in Chicago,
Illinois, and Lender shall be deemed to have received such items of payment on
the date specified in Section 3.5 hereof.

       3.2.   Unused Facility Fee.  From the date hereof, Borrower agrees to
pay to Lender a quarterly unused facility fee, equal to one-quarter percent
(0.25%) per annum of the average daily unused portion of the Commitment,
payable quarterly in arrears, the first payment being due on July l, 1997 and
continuing on the first day of each July, October, January and April thereafter
during the term of this Agreement and upon the termination hereof.

       3.3.   Term of Agreement; Termination.

              (A)    Subject to Lender's right to cease making Loans to
Borrower at any time upon or after the occurrence of a default or an Event of
Default, the provisions of this Agreement shall be in effect for a period from
the date hereof, through and including January 2, 1999 (the "Original Term").
Upon written request by Borrower, Lender may, in its sole and absolute
discretion, renew this Agreement for any number of successive one year periods
thereafter (a "Renewal Term"), but Lender shall have no obligation to do so.

              (B)    Upon at least 90 days prior written notice to Lender,
Borrower may, at its option, terminate this Agreement; provided, however, no
such termination shall be effective until Borrower has paid all of the
Obligations in immediately available funds.  It is understood that Borrower may
elect to terminate this Agreement in its entirety only; no section or lending
facility may be terminated singly.

              (C)    In addition to and not in limitation of any other
provision of this Agreement, the parties hereto agree that this Agreement shall
also be deemed terminated upon the effective date of the termination of the
Sepco Loan Agreement.

              (D)    At the effective date of any termination of this
Agreement, Borrower shall pay to Lender (in addition to the then outstanding
principal, accrued interest and other charges owing under this Agreement and
any of the Other Agreements), as liquidated damages for the loss of the bargain
and not as a penalty, an amount equal to 0.5% of the highest of the Average
Monthly Loan Balances outstanding pursuant to Section 2.1 during the twelve
month period ending on the date of termination if termination occurs at any
time prior to January 2, 1999 or during any Renewal Term thereafter.  If
termination occurs on the last day of the Original Term or the last day of any
Renewal Term, no termination charge shall be payable.

              (E)    All of the Obligations shall be forthwith due and payable
upon any termination of this Agreement.  Except as otherwise expressly provided
in this Agreement or any of the Other Agreements, no termination or
cancellation (regardless of cause or procedure) of this Agreement or any of the
Other Agreements shall in any way affect or impair the rights, powers or
privileges of Lender or the obligations or liabilities of Borrower in any way
relating to (i) any





LOAN AND SECURITY AGREEMENT - Page 17
<PAGE>   18
transaction or event occurring prior to such termination or cancellation or
(ii) any of the undertakings, agreements, covenants, warranties or
representations of Borrower contained in this Agreement or any of the Other
Agreements.  All such undertakings, agreements, covenants, warranties and
representations of Borrower shall survive such termination or cancellation,
and, notwithstanding such termination or cancellation, Lender shall retain its
Liens in the Collateral and all of its rights and remedies under this Agreement
and the Other Agreements until Borrower has paid the Obligations to Lender, in
full, in immediately available funds.

       3.4.   Payments. Except where evidenced by notes or other instruments
issued or made by Borrower to Lender specifically containing payment provisions
which are in conflict with this Section 3.4 (in which event the conflicting
provisions of said notes or other instruments shall govern and control), the
Obligations shall be payable as follows:

              (A)    Principal payable on account of Revolving Credit Loans
made by Lender to Borrower, shall be payable by Borrower to Lender immediately
upon the earliest of (i) the receipt by Lender or Borrower of any proceeds of
any of the Collateral, to the extent of said proceeds, (ii) the occurrence of
an Event of Default in consequence of which Lender elects to accelerate the
maturity and payment of the Obligations, or (iii) termination of this
Agreement; provided, however, that if the principal balance of Revolving Credit
Loans outstanding at any time shall exceed the Borrowing Base at such time,
Borrower shall, on demand, repay the Revolving Credit Loans in an amount
sufficient to reduce the aggregate unpaid principal amount of such Revolving
Credit Loans by an amount equal to such excess.

              (B)    Interest accrued on the Obligations shall be due on the
earliest of (i) the first day of each month (for the immediately preceding
month), computed through the last calendar day of the preceding month, (ii) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the Obligations, or (iii) termination of
this Agreement; provided, however, that Borrower hereby irrevocably authorizes
Lender, in Lender's sole discretion, to advance to Borrower, and to charge to
the Loan Account hereunder as a Revolving Credit Loan, a sum sufficient each
month to pay all interest accrued on the Obligations during the immediately
preceding month, and to pay all costs, fees and expenses at any time owed by
Borrower to Lender hereunder.

              (C)    The balance of the Obligations requiring the payment of
money, if any, shall be payable by Borrower to Lender as and when provided in
this Agreement or the Other Agreements, or on demand, whichever is earlier.

       3.5.   Application of Payments and Collections.  All items of payment
received by Lender by 12:00 noon, Dallas, Texas time, on any Business Day,
shall be deemed received on that Business Day.  All items of payment received
after 12:00 noon, Dallas, Texas time, on any Business Day, shall be deemed
received on the following Business Day.  Borrower irrevocably waives the right
to direct the application of any and all payments and collections at any time
or times hereafter received by Lender from or on behalf of Borrower, and
Borrower does hereby irrevocably agree that Lender shall have the continuing
exclusive right to apply and reapply any and all such payments and collections
received at any time or times hereafter by Lender or its





LOAN AND SECURITY AGREEMENT - Page 18
<PAGE>   19
agent against the Obligations, in such manner as Lender may deem advisable,
notwithstanding any entry by Lender upon any of its books and records.  If as
the result of collections of Accounts as authorized by Section 5.4 hereof a
credit balance exists in the Loan Account, such credit balance shall not accrue
interest in favor of Borrower, but shall be available to Borrower at any time
or times for so long as no Default or Event of Default exists; provided,
however, Lender may offset such credit against the Obligations upon or after
the occurrence of any Event of Default.

       3.6.   Statements of Account.  Lender will account to Borrower monthly
with a statement of Loans, charges and payments made pursuant to this
Agreement, and such account rendered by Lender shall be deemed final, binding
and conclusive upon Borrower unless Lender is notified by Borrower in writing
to the contrary within 30 days of the date each account is mailed to Borrower.
Such notice shall only be deemed an objection to those items specifically
objected to therein.

       3.7.   Additional Provisions Regarding Eurodollar Loans.

              (A)    Manner of Borrowing a Eurodollar Loan.  Borrower shall
give Lender notice of its intention to borrow a Eurodollar Loan in the form of
Exhibit A attached hereto (a "Eurodollar Borrowing Notice"), in which notice
Borrower shall specify (x) the aggregate amount of such Eurodollar Loan, (y)
the requested date of such Eurodollar Loan, and (z) the Eurodollar Interest
Period applicable thereto.  Borrower shall give Lender the Eurodollar Borrowing
Notice at least two (2) Business Days prior to the requested date of the
Eurodollar Loan.  With respect to such Eurodollar Loans, (i) each Eurodollar
Loan shall be in an integral multiple of $1,000,000, (ii) no more than four (4)
Eurodollar Interest Periods may be in existence at any one time, and (iii)
Borrower may not request a Eurodollar Loan if there exists a Default or Event
of Default.  The Borrower shall select Eurodollar Interest Periods with respect
to Eurodollar Loans so that no Eurodollar Interest Period expires after the end
of the Original Term, or if extended pursuant to Section 3.3(A), any Renewal
Term.  An outstanding Revolving Credit Loan may be converted to a Eurodollar
Loan at any time subject to the provisions of this Section 3.7.

              (B)    Interest on Eurodollar Loans.  Each Eurodollar Loan shall
bear interest from and including the first day of the Eurodollar Interest
Period applicable thereto (but not including the last day of such Eurodollar
Interest Period) at the interest rate determined as applicable to such
Eurodollar Loan, but interest on such Eurodollar Loan shall be payable as
provided in Section 3.4.  If at the end of a Eurodollar Interest Period for an
outstanding Eurodollar Loan, Borrower has failed to deliver to Lender a new
Eurodollar Borrowing Notice with respect to such Eurodollar Loan or to pay such
Eurodollar Loan, then such Eurodollar Loan shall be converted to a Revolving
Credit Loan bearing interest at a rate, and subject to all other terms and
conditions of this Agreement, applicable to Revolving Credit Loans not
constituting Eurodollar Loans on and after the last day of such Eurodollar
Interest Period until paid or until the effective date of a new Eurodollar
Borrowing Notice with respect thereto.





LOAN AND SECURITY AGREEMENT - Page 19
<PAGE>   20
              (C)    Availability of Eurodollar Loans.  If Lender determines
that maintenance of any of its Eurodollar Loans would violate any applicable
law, rule, regulation or directive, whether or not having the force of law,
Lender shall suspend the availability of Eurodollar Loans and require any
Eurodollar Loans outstanding to be repaid (provided, that, without in any way
impairing Borrower's obligations under Section 3.7(D) and Section 3.7(E), to
the extent that Borrower is entitled to request a Revolving Credit Loan bearing
interest at the Base Rate, Borrower may request such a Revolving Credit Loan in
order to repay the Eurodollar Loans); or if Lender determines that (x) deposits
of a type or maturity appropriate to match fund Eurodollar Loans are not
available or (y) the Eurodollar Base Rate does not accurately reflect the cost
of making a Eurodollar Loan, then Lender shall suspend the availability of
Eurodollar Loans after the date of any such determination.

              (D)    Funding Indemnification. If any payment of a Eurodollar
Loan occurs on a date which is not the last day of the applicable Eurodollar
Interest Period, whether because of acceleration, prepayment or otherwise, or a
Eurodollar Loan is not made on the date specified by Borrower because Borrower
has not satisfied the conditions precedent to such Eurodollar Loan contained in
this Agreement or has otherwise breached the terms of this Agreement, Borrower
will indemnify Lender for any loss or cost incurred by it resulting therefrom,
including without limitation any loss or cost in liquidating or employing
deposits acquired to fund or maintain the Eurodollar Loan.

              (E)    Lender Statements: Survival of Indemnity.  Within sixty
(60) days of the date upon which Lender suspends the availability of Eurodollar
Loans under Section 3.7(C) hereof or learns of any loss or cost for which
Borrower has indemnified Lender under Section 3.7(D) hereof, Lender shall
deliver a written statement as to the amount due under Section 3.7(C) or (D).
Such written statement shall set forth in reasonable detail the calculations
and basis therefor upon which Lender determined such amount and shall be final,
conclusive and binding on Borrower in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though the Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding
to the deposit used as a reference in determining the Eurodollar Base Rate
applicable to such Eurodollar Loan whether in fact that is the case or not.
Unless otherwise provided herein, the amount specified in the written statement
shall be payable on demand after receipt by Borrower of the written statement.

       3.8.   Yield Protection. If either (i) the adoption of any applicable
law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by Lender with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall subject Lender to any tax (including without limitation any United
States interest equalization or similar tax, however named), duty or other
charge with respect to any Eurodollar Loan or Lender's obligation to compute
interest on the principal balance of any Eurodollar Loan at a rate based upon
the Eurodollar Base Rate, or shall change the basis of taxation of payments to
Lender of the principal of or interest on any Eurodollar Loan or any other
amounts due under this Agreement in





LOAN AND SECURITY AGREEMENT - Page 20
<PAGE>   21
respect of any Eurodollar Loan or Lender's obligation to compute the interest
on the principal balance of any Eurodollar Loan at a rate based upon the
Eurodollar Base Rate, or (ii) 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), special deposit or similar requirement against
assets of, deposits with or for the account of, or credit extended by, Lender,
or shall impose on Lender (or its eurodollar lending office) or any relevant
interbank eurodollar market any other condition affecting any Eurodollar Loan
or Lender's obligation to compute the interest on the principal balance of any
Eurodollar Loan at a rate based upon the Eurodollar Base Rate; and the result
of any of the foregoing is to increase the cost to Lender of maintaining any
Eurodollar Loans, or to reduce the amount of any sum received or receivable by
Lender under this Agreement by an amount deemed by Lender to be material, then
upon demand by Lender, Borrower shall pay to Lender such additional amount or
amounts as will compensate Lender for such increased cost or reduction.  Lender
will promptly notify Borrower of any event of which it has knowledge, occurring
after the date hereof, which will entitle Lender to compensation pursuant to
this Section 3.8.  A certificate of Lender claiming compensation under this
Section 3.8 and setting forth the additional amount or amounts to be paid to
Lender hereunder shall be conclusive in the absence of manifest error.

       3.9    Closing Fee.  Borrower agrees to pay to Lender on the date of
execution of this Agreement, a closing fee equal to $10,000, which fee shall be
deemed fully earned and non-refundable as of the date of execution of this
Agreement.

SECTION 4.    COLLATERAL:  GENERAL TERMS

       4.1.   Security Interest in Collateral.  To secure the prompt payment
and performance to Lender of the Obligations, Borrower hereby grants to Lender
a continuing security interest in and Lien upon all of the Property and
interests in Property of Borrower, whether now owned or existing or hereafter
created, acquired or arising and wheresoever located including, without
limitation, the following:

              (A)    Accounts;

              (B)    Inventory;

              (C)    Equipment;

              (D)    General Intangibles;

              (E)    All investment property (as defined in Section 9.115 of
the Code);

              (F)    All real Property;

              (G)    all monies and other Property of any kind, now or at any
time or times hereafter, in the possession or under the control of Lender or a
bailee of Lender;





LOAN AND SECURITY AGREEMENT - Page 21
<PAGE>   22
              (H)    all accessions to, substitutions for and all replacements,
products and cash and non-cash proceeds of (A), (B), (C), (D), (E), (F) and (G)
above, including, without limitation, Proceeds of and unearned premiums with
respect to insurance Policies insuring any of the Collateral; and

              (I)    all books and records (including, without limitation,
customer lists, credit files, computer programs, print-outs, and other computer
materials and records) of Borrower pertaining to any of (A), (B), (C), (D),
(E), (F), (G) or (H) above.

       4.2.   Lien Perfection.  Borrower agrees to execute the UCC-l financing
statements provided for by the Code or otherwise together with any and all
other instruments, assignments or documents and shall take such other action as
may be reasonably required to perfect or to continue the perfection of Lender's
security interest in the Collateral as a first priority Lien subject to
Permitted Liens only.  Unless prohibited by applicable law, Borrower hereby
authorizes Lender to execute and file any such financing statement on
Borrower's behalf.  The parties agree that a carbon, Photographic or other
reproduction of this Agreement shall be sufficient as a financing statement and
may be filed in any appropriate office in lieu thereof.

       4.3.   Location of Collateral.  All Collateral, other than Inventory in
transit, will at all times be kept by Borrower at one or more of the business
locations set forth in Exhibit B and shall not, without the prior written
approval of Lender, be moved therefrom except, prior to an Event of Default,
for sales of Inventory in the ordinary course of business and dispositions of
Equipment that are authorized by Section 7.2 hereof.

       4.4.   Insurance of Collateral.  Borrower agrees to maintain and pay for
insurance upon all Collateral wherever located, in storage or in transit in
vehicles, including goods evidenced by documents, covering casualty, hazard,
public liability and such other risks and in such amounts and with such
insurance companies as shall be reasonably satisfactory to Lender to insure
Lender's interest in the Collateral.  Borrower shall deliver the originals of
such policies to Lender with satisfactory endorsements naming Lender as loss
payee and as mortgagee pursuant to a standard mortgagee clause.  Each policy of
insurance or endorsement shall contain a clause requiring the insurer to give
not less than 30 days prior written notice to Lender in the event of
cancellation of the policy for any reason whatsoever and a clause that the
interest of Lender shall not be impaired or invalidated by any act or neglect
of Borrower or owner of the Property nor by the occupation of the premises for
purposes more hazardous than are permitted by said policy.  If Borrower fails
to provide and pay for such insurance, Lender may, at Borrower's expense,
procure the same, but shall not be required to do so.  Borrower agrees to
deliver to Lender, promptly as rendered, true copies of all reports made in any
reporting forms to insurance companies.

       4.5.   Protection of Collateral.  All insurance expenses and all
expenses of protecting, storing, warehousing, insuring, handling, maintaining
and shipping the Collateral, any and all taxes imposed by any governmental
authority on any Collateral or in respect of the sale thereof shall be borne
and paid by Borrower.  If Borrower fails to promptly pay any portion thereof
when





LOAN AND SECURITY AGREEMENT - Page 22
<PAGE>   23
due, Lender may, at its option, but shall not be required to, pay the same and
charge the Loan Account therefor.  Borrower agrees to reimburse Lender promptly
therefor with interest accruing thereon daily at the Default Rate.  All sums so
paid or incurred by Lender for any of the foregoing and all reasonable costs
and expenses (including reasonable attorneys' fees, legal expenses, and court
costs) which Lender may incur in enforcing or protecting its Lien on or rights
and interest in the Collateral or any of its rights or remedies, together with
interest at the Default Rate, shall be considered Obligations hereunder secured
by all Collateral.  Lender shall not be liable or responsible in any way for
the safekeeping of any Collateral or for any loss or damage thereto (except for
reasonable care in the custody thereof while any Collateral is in Lender's
actual possession) or for any diminution in the value thereof, or for any act
or default of any warehouseman, carrier, forwarding agency, or other person
whomsoever, but the same shall be at Borrower's sole risk.

SECTION 5.    PROVISIONS RELATING TO ACCOUNTS

       5.1.   Representations, Warranties and Covenants.  With respect to all
Accounts, Borrower represents and warrants to Lender that Lender may rely, in
determining which Accounts are Eligible Accounts, on all statements and
representations made by Borrower with respect to any Account or Accounts, and,
unless otherwise indicated in writing to Lender, that with respect to each
Account:  it is genuine and in all respects what it purports to be, and it is
not evidenced by a judgment; it arises out of a completed, bona fide sale and
delivery of goods or rendition of services by Borrower in the ordinary course
of its business and in accordance with the terms and conditions of all purchase
orders, contracts or other documents relating thereto and forming a part of the
contract between Borrower and the Account Debtor; it is for a liquidated amount
maturing as stated in the duplicate invoice covering such sale or rendition of
services; such Account, and Lender's security interest therein, is not, and
will not be in the future, subject to any offset, Lien, deduction, defense,
dispute, counterclaim or any other adverse condition except for disputes
resulting in returned goods where the amount in controversy is deemed by Lender
to be immaterial, and each such Account is absolutely owing to Borrower and is
not contingent in any respect or for any reason; Borrower has made no agreement
with any Account Debtor thereunder for any deduction therefrom, except
discounts or allowances which are granted by Borrower in the ordinary course of
its business for prompt payment and which are reflected in the calculation of
the net amount of each respective invoice related thereto; there are no facts,
events or occurrences which in any way impair the validity or enforceability
thereof or tend to reduce the amount payable thereunder from the face amount of
the invoice and statements delivered to Lender with respect thereto; to the
best of Borrower's knowledge, the Account Debtor thereunder is Solvent and, at
the time any contract or other document giving rise to the Account was
executed, such Account Debtor had the capacity to contract; and Borrower has no
knowledge of any fact or circumstance which would impair the validity or
collectibility of such Account.

       5.2.   Assignments, Records and Schedules of Accounts.  If requested to
do so by Lender, Borrower shall execute and deliver to Lender formal written
assignments of all of its Accounts weekly (or, if requested by Lender, daily),
together with copies of invoices or invoice registers related thereto.
Borrower shall keep accurate and complete records of its Accounts and





LOAN AND SECURITY AGREEMENT - Page 23
<PAGE>   24
all payments and collections thereon and shall submit to Lender on a daily
basis a sales and collections report for the preceding day, in form
satisfactory to Lender.  On or before the fifteenth day of each month from and
after the date hereof, Borrower shall deliver to Lender, in form satisfactory
to Lender, a detailed aged trial balance of all Accounts existing as of the
last day of the preceding month, specifying the names, addresses, face value,
dates of invoices and due dates for each Account Debtor obligated on an Account
so listed ("Schedule of Accounts"), and, upon Lender's request therefor, copies
of proof of delivery and the original copy of all documents, including, without
limitation, repayment histories and present status reports relating to the
Accounts so scheduled and such other matters and information relating to the
status of then existing Accounts as Lender shall reasonably request.  If any
amounts due and owing in excess of $25,000 are in dispute between Borrower and
any Account Debtor, Borrower shall provide Lender with written notice thereof
at the time of submission of the next Schedule of Accounts, explaining in
detail the reason for the dispute, all claims related thereto and the amount in
controversy.

       5.3.   Administration of Accounts.  Upon the granting of any discounts,
allowances or credits by Borrower that are not shown on the face of the invoice
for the Account involved, Borrower shall promptly report such discounts,
allowances or credits, as the case may be, to Lender and in no event later than
the time of its submission to Lender of the next Schedule of Accounts as
provided in Section 5.2.  If an Account includes a charge for any tax payable
to any governmental taxing authority, Lender is authorized, in its sole
discretion, to pay the amount thereof to the proper taxing authority for the
account of Borrower and to charge the Loan Account therefor.  Whether or not a
Default or an Event of Default has occurred, Lender shall have the right, at
any time or times hereafter, in the name of Lender, any designee of Lender or
Borrower, to verify the validity, amount or any other matter relating to any
Accounts by mail, telephone, telegraph or otherwise.  Borrower shall cooperate
fully with Lender in an effort to facilitate and promptly conclude any such
verification process.

       5.4.   Collection of Accounts.  To expedite collection, Borrower shall
endeavor in the first instance to make collection of its Accounts for Lender.
All remittances received by Borrower on account of Accounts shall be held as
Lender's property by Borrower as trustee of an express trust for Lender's
benefit and Borrower shall immediately deposit same in the Dominion Account.
After the occurrence of an Event of Default, Lender shall have the right to
notify Account Debtors that Accounts have been assigned to Lender and to
collect Accounts directly in its own name and to charge the collection costs
and expenses, including reasonable attorneys' fees, to Borrower.  Lender has no
duty to protect, insure, collect or realize upon the Accounts or preserve
rights in them.

SECTION 6.    PROVISIONS RELATING TO INVENTORY

       6.1.   Representations, Warranties and Covenants.  With respect to
Inventory, Borrower represents and warrants to Lender that Lender may rely, in
determining which items of Inventory constitute Eligible Inventory, on all
statements and representations made by Borrower with respect to any Inventory
and that:  All Inventory is presently and will continue to be located at
Borrower's places of business listed on Exhibit B and will not be removed
therefrom except as





LOAN AND SECURITY AGREEMENT - Page 24
<PAGE>   25
authorized by Section 4.3 of this Agreement; no Inventory is now, nor shall any
Inventory at any time or times hereafter be, stored with a bailee, warehouseman
or similar party without Lender's prior written consent; no Inventory is or
will be consigned to any Person without Lender's prior written consent; and no
Inventory is or will be produced in violation of the Fair Labor Standards Act.

       6.2.   Inventory Reports.  Borrower agrees to furnish Lender with
Inventory reports at such times as Lender may request, but at least once each
month.  Such reports shall be in form and detail satisfactory to Lender.
Borrower shall conduct a physical inventory no less frequently than annually
and shall provide to Lender a report based on each such physical inventory
promptly thereafter, together with such supporting information as Lender shall
in its discretion request.

       6.3.   Returns of Inventory.  If at any time or times hereafter any
Account Debtor returns any Inventory to Borrower the shipment of which
generated an Account on which such Account Debtor is obligated in excess of
$20,000, Borrower shall notify Lender of the same immediately, specifying the
reason for such return and the location and condition of the returned
Inventory.

SECTION 7.    PROVISIONS RELATING TO EQUIPMENT

       7.1.   Representations, Warranties and Covenants.  With respect to the
Equipment, Borrower represents, warrants and covenants to and with Lender that
the Equipment is in good operating condition and repair, and all necessary
replacements of and repairs thereto shall be made so that the value and
operating efficiency of the Equipment shall be maintained and preserved,
reasonable wear and tear excepted.  Borrower will not permit any of the
Equipment to become affixed to any real Property leased to Borrower so that an
interest arises therein under the real estate laws of the applicable
jurisdiction unless the landlord of such real Property has executed a landlord
waiver or leasehold mortgage in favor of Lender, and Borrower will not permit
any of the Equipment to become an accession to any personal Property other than
Equipment subject to first priority Liens in favor of Lender or subject to
Permitted Liens.  Immediately on request therefor by Lender, Borrower shall
deliver to Lender any and all evidence of ownership, if any, of any of the
Equipment (including, without limitation, certificates of title and
applications for title).  Borrower shall maintain accurate records itemizing
and describing the kind, type, quality, quantity and value of its Equipment and
all dispositions made in accordance with Section 7.2 hereof, and shall furnish
Lender with a current schedule containing the foregoing information on at least
an annual basis and more often if requested by Lender.

       7.2.   Dispositions of Equipment.  Borrower will not sell, lease or
otherwise dispose of or transfer any of the Equipment or any part thereof
without the prior written consent of Lender; provided, however, that the
foregoing restriction shall not apply, for so long as no Default or Event of
Default exists, to (A) dispositions of Equipment which, in the aggregate during
any consecutive twelve-month period, has a fair market value or book value,
whichever is less, of $50,000 or less, provided that all proceeds thereof are
turned over to Lender, or (B) replacements





LOAN AND SECURITY AGREEMENT - Page 25
<PAGE>   26
of Equipment that is substantially worn, damaged or obsolete with Equipment of
like kind, function and value, provided that the replacement Equipment shall be
acquired prior to or concurrently with any disposition of the Equipment that is
to be replaced, the replacement Equipment shall be free and clear of Liens
other than Permitted Liens, Borrower shall give Lender at least five days prior
written notice of such disposition and Borrower shall turn over to Lender all
proceeds realized from any such disposition.

SECTION 8.    REPRESENTATIONS AND WARRANTIES

       8.1.   General Representations and Warranties.  To induce Lender to
enter into this Agreement and to make advances hereunder, Borrower warrants,
represents and covenants to Lender as follows:

              (A)    Borrower is a corporation duly organized, validly existing
and in good standing under the laws of the State of Nevada; has duly qualified
and is authorized to do business and is in good standing as a foreign
corporation in all states and jurisdictions where the character of its
Properties or the nature of its activities make such qualification necessary,
including, without limitation, the State of Louisiana and the State of Texas;
and has not been known as or used any corporate, fictitious or trade names in
the past seven years except as disclosed on Exhibit C attached hereto and made
a part hereof.

              (B)    Borrower has the right and power and is duly authorized to
enter into, deliver and perform this Agreement and each of the Other Agreements
to which it is a party, and this Agreement is, and each of the Other Agreements
when delivered under this Agreement will be, a legal, valid and binding
obligation of Borrower enforceable against it in accordance with their
respective terms.

              (C)    Borrower is not engaged principally, or as one of its
important activities, in the business of purchasing or carrying "margin stock"
(within the meaning of Regulation G or U of the Board of Governors of the
Federal Reserve System), and no part of the proceeds of any Loans to Borrower
will be used to purchase or carry any margin stock or to extend credit to
others for the purpose of purchasing or carrying any margin stock, or be used
for any purpose which violates or is inconsistent with the provisions of
Regulations G, T, U or X of said Board of Governors.

              (D)    Borrower has, and is in good standing with respect to, all
governmental consents, approvals, authorizations, permits, certificates,
inspections, and franchises which materially affect its ability to conduct its
business as heretofore or proposed to be conducted by it and to own or lease
and operate its Properties as now owned or leased by it.

              (E)    Borrower owns or possesses all the patents, trademarks,
service marks, trade names, copyrights and licenses necessary for the present
and planned future conduct of its business without any known conflict with the
rights of others.





LOAN AND SECURITY AGREEMENT - Page 26
<PAGE>   27
              (F)    Except as set forth on Exhibit D attached hereto and made
a part hereof, there are no actions, suits, proceedings or investigations
pending, or to the knowledge of Borrower, threatened, against or affecting
Borrower or any of its Properties in any court or before any governmental
authority or arbitration board or tribunal, and no action, suit, proceeding or
investigation shown on Exhibit D involves the possibility of materially and
adversely affecting the Properties or condition (financial or otherwise) of
Borrower or the ability of Borrower to perform this Agreement.

              (G)    Borrower has good, indefeasible and marketable title to
and fee simple ownership of, or valid and subsisting leasehold interests in,
all of its real Property, and good title to all of its other Property, in each
case, free and clear of all Liens except Permitted Liens.

              (H)    The balance sheet of Borrower and such other Persons
described therein as of March 31, 1997, and the related statements of income,
for the periods ended on such dates, have been prepared, to the best of
Borrower's knowledge, in accordance with GAAP (except for changes in
application in which Borrower's independent certified public accountants
concur), and present fairly the financial positions of Borrower at such dates
and the results of Borrower's operations for such periods.  Since March 31,
1997, there has been no material change in the condition, financial or
otherwise, of Borrower and such other Persons as shown on the balance sheet as
of such date and no change in the aggregate value of Equipment and real
Property owned by Borrower or such other Persons, except changes in the
ordinary course of business, none of which individually or in the aggregate has
been materially adverse.  The fiscal year of Borrower for accounting purposes
ends on [September 30] of each year.

              (I)    There is no fact which Borrower has failed to disclose to
Lender in writing which materially affects adversely or, so far as Borrower can
now foresee, will materially affect adversely the Properties, business,
prospects, profits, or condition (financial or otherwise) of Borrower or the
ability of Borrower to perform this Agreement.

              (J)    Borrower has not received any notice to the effect that it
is not in full compliance with any of the requirements of ERISA and the
regulations promulgated thereunder.  No fact or situation that could result in
a material adverse change in the financial condition of Borrower (including,
but not limited to, any Reportable Event or Prohibited Transaction) exists in
connection with any Plan.  Borrower has no withdrawal liability in connection
with a Multi-Employer Plan.

              (K)    Borrower has filed all federal, state and local tax
returns and other reports it is required by law to file and has paid, or made
provision for the payment of, all taxes, assessments, fees and other
governmental charges that are due and payable.

              (L)    Borrower has duly complied with, and its Properties,
business operations and leaseholds are in compliance in all material respects
with, the provisions of all federal, state and local laws, rules and
regulations applicable to Borrower, its Properties or the conduct of its
business.





LOAN AND SECURITY AGREEMENT - Page 27
<PAGE>   28
              (M)    No Default or Event of Default will exist or result from
the execution and delivery of this Agreement or Borrower's performance
hereunder.

              (N)    There are no claims for brokerage commissions, finder's
fees or investment banking fees in connection with the transactions
contemplated by this Agreement.

       8.2.   Reaffirmation and Survival of Representations.  Each request for
a Loan made by Borrower pursuant to this Agreement or any of the Other
Agreements shall constitute (A) an automatic representation and warranty by
Borrower to Lender that there does not then exist any Default or Event of
Default, and (B) a reaffirmation as of the date of said request of all of the
representations and warranties of Borrower contained in this Agreement and the
Other Agreements are true in all material respects, except for any changes in
the nature of Borrower's business or operations that would render the
information contained in any exhibit hereto either materially inaccurate or
materially incomplete, so long as Lender has consented to such changes or such
changes are expressly permitted by this Agreement.  Borrower covenants,
warrants and represents to Lender that all representations and warranties of
Borrower contained in this Agreement or any of the Other Agreements shall be
true at the time of Borrower's execution of this Agreement and the Other
Agreements, and shall survive the execution, delivery and acceptance thereof by
Lender and the parties thereto and the closing of the transactions described
therein or related thereto.

SECTION 9.    COVENANTS AND CONTINUING AGREEMENTS

       9.1.   Affirmative Covenants.  During the term of this Agreement, and
thereafter for so long as there are any Obligations to Lender, Borrower
covenants that, unless otherwise consented to by Lender in writing, it shall:

              (A)    Pay and discharge all taxes, assessments and governmental
charges upon it, its income and Properties as and when such taxes, assessments
and charges are due and payable, except and to the extent only that such taxes,
assessments and charges are being actively contested in good faith and by
appropriate proceedings, Borrower maintains adequate reserves on its books
there for and the nonpayment of such taxes does not result in a Lien upon any
Properties or Borrower other than a Permitted Lien.  Borrower shall also pay
and discharge any lawful claims which, if unpaid, might become a Lien against
any of Borrower's Properties except for Permitted Liens.

              (B)    File all federal, state and local tax returns and other
reports Borrower is required by law to file and maintain adequate reserves for
the payment of all taxes, assessments, governmental charges, and levies imposed
upon it, its income, or its profits, or upon any Property belonging to it.

              (C)    Pay to Lender, on demand, any and all fees, costs or
expenses which Lender pays to a bank or other similar institution (including,
without limitation, any reasonable fees paid by Lender to any Participating
Lender) arising out of or in connection with (i) the forwarding to Borrower or
any other Person on behalf of Borrower, by Lender of proceeds of





LOAN AND SECURITY AGREEMENT - Page 28
<PAGE>   29
loans made by Lender to Borrower pursuant to this Agreement and (ii) the
depositing for collection, by Lender, of any check or item of payment received

become directly or contingently liable with respect to the Indebtedness of any

be effectively stayed and bonded on appeal in a manner satisfactory to Lender
for the full amount thereof, the validity and amount of the claims secured
thereby are being actively contested in good faith and by appropriate lawful
proceedings and such Liens do not, in the aggregate, materially detract from
the value of the Property of Borrower or materially impair the use thereof in
the operation of Borrower's business; (vi) reservations, exceptions, easements,
rights of way, and other similar encumbrances affecting real Property, provided
that, in Lender's judgment, they do not in the aggregate materially detract
from the value of said Properties or materially interfere

Property constitutes Collateral, Lender has consented thereto; and (vii) such

Lender to perfect or continue the perfection of Lender's Lien and security
interest hereunder.

Inventory or Equipment in its then condition, or after any further
manufacturing or processing thereof, at public or private sale or sales, with
such notice as may be required by law, in lots or in bulk, for cash or on
credit, all as Lender, in its discretion, may deem advisable.  Borrower agrees
that fifteen days written notice to Borrower of any public or private sale or
other disposition of such Collateral shall be reasonable notice thereof, and
such sale shall be at such locations as Lender may designate in said notice.
Lender shall have the right to conduct such sales on Borrower's premises,
without charge therefor, and such sales may be adjourned from time to time in
accordance with applicable law.  Lender shall have the right to sell, lease or
otherwise dispose of such Collateral, or any part thereof, for cash, credit or
any combination thereof, and Lender may purchase all or any part of such
Collateral at public or, if permitted by law, private sale and, in lieu of
actual payment of such purchase price, may set-off the amount of such price
against the Obligations.

              (D)    Lender is hereby granted a license or other right to use,
without charge, Borrower's labels, patents, copyrights, rights of use of any
name, trade secrets, tradenames, trademarks and advertising matter, or any
Property of a similar nature, as it pertains to the Collateral, in advertising
for sale and selling any Collateral and Borrower's rights under all licenses
and all franchise agreements shall inure to Lender's benefit.

              (E)    The proceeds realized from the sale of any Collateral may
be applied, after allowing two Business Days for collection, first to the
costs, expenses and reasonable attorneys' fees incurred by Lender in collecting
the Obligations, in enforcing Lender's rights under the Loan Documents and in
collecting, retaking, completing, protecting, removing, storing, advertising
for sale, selling and delivering any of the Collateral; secondly, to interest
due upon any of the Obligations; and thirdly, to the principal of the
Obligations.  If any deficiency shall arise, Borrower shall remain liable to
Lender therefor.

       11.4.  Remedies Cumulative; No Waiver.  All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the Other Agreements, or in any
document referred to herein or contained in any agreement supplementary hereto
or in any schedule given to Lender or contained in any other agreement between
Lender and Borrower, heretofore, concurrently, or hereafter entered into, shall
be deemed cumulative to and not in derogation or substitution of any of the
terms, covenants, conditions, or agreements of Borrower herein contained.  The
failure or delay of Lender to exercise or enforce any rights, Liens, powers or
remedies hereunder or under any of the aforesaid agreements or other documents
or security or Collateral shall not operate as a waiver of such Liens, rights,
powers and remedies, but all such Liens, rights, powers, and remedies shall
continue in full force and effect until all Loans and all other Obligations
owing or to become owing from Borrower to Lender shall have been fully
satisfied, and all Liens, rights, powers, and remedies herein provided for are
cumulative and none are exclusive.

SECTION 12.   MISCELLANEOUS

       12.1.  Power of Attorney. Borrower hereby irrevocably designates, makes,
constitutes and appoints Lender (and all Persons designated by Lender) as
Borrower's true and lawful





LOAN AND SECURITY AGREEMENT - Page 39
<PAGE>   40
attorney (and agent-in-fact) and Lender, or Lender's agent, may, without notice
to Borrower and in either Borrower's or Lender's name, but at the reasonable
cost and expense of Borrower:

              (A)    At such time or times hereafter as Lender or said agent
may determine, endorse Borrower's name on any checks, notes, acceptances,
drafts, money orders or any other evidence of payment or proceeds of the
Collateral which come into the possession of Lender or under Lender's control;
and

              (B)    At such time or times upon or after the occurrence of an
Event of Default as Lender or its agent may determine:  (i) demand and enforce
payment of the Accounts by legal proceedings or otherwise and exercise
generally all of Borrower's rights and remedies with respect to the collection
of the Accounts; (ii) settle, adjust, compromise, discharge or release any of
the Accounts or other Collateral or any legal proceedings brought to collect
any of the Accounts or other Collateral; (iii) prepare, file and sign
Borrower's name to a proof of claim in bankruptcy or similar document against
any Account Debtor or to any notice of lien, assignment or satisfaction of lien
or similar document in connection with any of the Collateral; (iv) receive and
open all mail addressed to Borrower and to notify postal authorities to change
the address for delivery thereof to such address as Lender may designate; (v)
endorse the name of Borrower upon any of the items of payment or proceeds
relating to any Collateral and deposit the same to the account of Lender on
account of the Obligations; (vi) endorse the name of Borrower upon any chattel
paper, document, instrument, invoice, freight bill, bill of lading or similar
document or agreement relating to the Accounts, Inventory and any other
Collateral; (vii) use Borrower's stationery and sign the name of Borrower to
verifications of the Accounts and notices thereof to Account Debtors; (viii)
make and adjust claims under policies of insurance; and (ix) do all other acts
and things necessary, in Lender's reasonable determination, to fulfill
Borrower's obligations under this Agreement.

       12.2.  Indemnity.  Borrower hereby agrees to indemnify Lender and hold
Lender harmless from and against any liability, loss, damage, suit, action or
proceeding ever suffered or incurred by Lender as the result of Borrower's
failure to observe, perform or discharge Borrower's duties hereunder.  Without
limiting the generality of the foregoing, this indemnity shall extend to any
claims asserted against Lender by any Person under any Environmental Laws or
similar laws by reason of Borrower's or any other Person's failure to comply
with laws applicable to solid or hazardous waste materials or other toxic
substances, but this indemnity shall specifically exclude liability for breach
of any Environmental Laws caused solely and directly by Lender.
Notwithstanding any contrary provision in this Agreement, the obligation of
Borrower under this Section 12.2 shall survive the payment in full of the
Obligations and the termination of Lender's obligation to make Revolving Credit
Loans.

       12.3.  Modification of Agreement.  This Agreement and the Other
Agreements may not be modified, altered or amended, except by an agreement in
writing signed by Borrower and Lender.

       12.4   Reimbursement of Expenses.  If, at any time or times prior or
subsequent to the date hereof, regardless of whether or not an Event of Default
then exists or any of the





LOAN AND SECURITY AGREEMENT - Page 40
<PAGE>   41
transactions contemplated hereunder are concluded, Lender employs counsel for
advice or other representation, or incurs legal expenses or other costs or out-
of-pocket expenses in connection with:  (A) the negotiation and preparation of
this Agreement or any of the Other Agreements, any amendment of or modification
of this Agreement or any of the Other Agreements; (B) the reasonable
administration of this Agreement or any of the Other Agreements and the
transactions contemplated hereby and thereby; (C) any litigation, contest,
dispute, suit, proceeding or action (whether instituted by Lender, Borrower or
any other Person) in any way relating to the Collateral, this Agreement or any
of the Other Agreements or Borrower's affairs (other than litigation in which
Borrower is the prevailing party and in which Lender is adverse to Borrower);
(D) any attempt to enforce any rights of Lender against Borrower or any other
Person which may be obligated to Lender by virtue of this Agreement or any of
the Other Agreements, including, without limitation, the Account Debtors (other
than litigation in which Borrower is the prevailing party and in which Lender
is adverse to Borrower); or (E) any attempt to inspect, verify, protect,
preserve, restore, collect, sell, liquidate or otherwise dispose of or realize
upon the Collateral; then, in any such event, the reasonable attorneys' fees
arising from such services and all expenses, costs, charges and other fees of
such counsel or of Lender or relating to any of the events or actions described
in this Section shall be payable, on demand, by Borrower to Lender and shall be
additional Obligations hereunder secured by the Collateral.  Additionally, if
any taxes (excluding taxes imposed upon or measured by the net income of
Lender) shall be payable on account of the execution or delivery of this
Agreement, or the execution, delivery, issuance or recording of any of the
Other Agreements, or the creation of any of the Obligations hereunder, by
reason of any existing or hereafter enacted federal or state statute, Borrower
will pay all such taxes, including, but not limited to, any interest and
penalties thereon, and will indemnify and hold Lender harmless from and against
liability in connection therewith.  Borrower shall have no obligation to pay
the legal expenses or other costs incurred by a Participating Lender or by
Lender in connection with any sale or attempted sale of any interest herein to
a Participating Lender.

       12.5.  Indulgences Not Waivers.  Lender's failure, at any time or times
hereafter, to require strict performance by Borrower of any provision of this
Agreement shall not waive, affect or diminish any right of Lender thereafter to
demand strict compliance and performance therewith.  Any suspension or waiver
by Lender of an Event of Default by Borrower under this Agreement or any of the
Other Agreements shall not suspend, waive or affect any other Event of Default
by Borrower under this Agreement or any of the Other Agreements, whether the
same is prior or subsequent thereto and whether of the same or of a different
type.  None of the undertakings, agreements, warranties, covenants and
representations of Borrower contained in this Agreement or any of the Other
Agreements and no Event of Default by Borrower under this Agreement or any of
the Other Agreements shall be deemed to have been suspended or waived by
Lender, unless such suspension or waiver is by an instrument in writing
specifying such suspension or waiver and is signed by a duly authorized
representative of Lender and directed to Borrower.

       12.6.  Severability.  Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be
prohibited by or invalid under applicable law, such provision shall be





LOAN AND SECURITY AGREEMENT - Page 41
<PAGE>   42
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Agreement.

       12.7.  Successors and Assigns; Participations by Lender.  This Agreement
and the Other Agreements shall be binding upon and inure to the benefit of the
successors and assigns of Borrower and Lender; provided, however, that Borrower
may not sell, assign or transfer any interest in this Agreement or any of the
Other Agreements, or any portion thereof, including, without limitation,
Borrower's rights, title, interests, remedies, powers and duties hereunder or
thereunder.  Any purported assignment by Borrower in violation of this Section
12.7 shall be void, without Lender's prior written consent.  Borrower hereby
consents to Lender's participation, sale, assignment, transfer or of the
disposition, at any time or times hereafter, of this Agreement, any of the
Other Agreements, or any other Obligations, or of any portion hereof or
thereof, including, without limitation, Lender's rights, title, interests,
remedies, powers, and duties hereunder or thereunder.  In the case of an
assignment, the assignee shall have, to the extent of such assignment, the same
rights, benefits and obligations as it would have if it were the original
"Lender" hereunder and Lender shall be relieved of all obligations hereunder
upon any such assignment.  In the case of a participation, each Participating
Lender shall be entitled to receive all information received by Lender
regarding the credit-worthiness of Borrower, including, without limitation,
information required to be disclosed to a participant pursuant to Banking
Circular 181 (Rev., August 2, 1984), issued by the Comptroller of the Currency
(whether such Participating Lender is subject to the circular or not).

       12.8.  Cumulative Effect; Conflict of Terms.  The provisions of the
Other Agreements are hereby made cumulative with the provisions of this
Agreement.  Except as otherwise provided in Section 3.4 of this Agreement and
except as otherwise provided in any of the Other Agreements by specific
reference to the applicable provision of this Agreement, if any provision
contained in this Agreement is in direct conflict with, or inconsistent with,
any provision in any of the Other Agreements, the provision contained in this
Agreement shall govern and control.

       12.9.  Execution in Counterparts.  This Agreement may be executed in any
number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to
be an original and all of which counterparts taken together shall constitute
but one and the same instrument.

       12.10. Notice.  Except as otherwise provided herein, all notices,
requests and demands to or upon a party hereto shall be in writing and shall be
sent by certified or registered mail, return receipt requested, personal
delivery against receipt, or by telegraph or telex and, unless otherwise
expressly provided herein, shall be deemed to have been validly served, given
or delivered when delivered against receipt or three Business Days after
deposit in the mail, postage prepaid, or, in the case of telegraphic notice,
when delivered to the telegraph company, or, in the case of telex notice, when
sent, answer-back received, addressed as follows:

or to such other address as each party may designate for itself by like notice
given in accordance with this Section 12.10; provided, however, that any
notice, request or demand to or upon Lender pursuant to Section 3.3 shall not
be effective until received by Lender.  Any written notice that is not sent in
conformity with the provisions hereof shall nevertheless be effective on the
date such notice is actually received by the noticed party.

       12.11. Lender's Consent.  Whenever Lender's consent is required to be
obtained under this Agreement or any of the Other Agreements as a condition to
any action, inaction, condition or event, Lender shall be authorized to give or
withhold such consent in its sole and absolute discretion (unless otherwise
expressly provided herein) and to condition its consent upon the giving of
additional collateral security for the Obligations, the payment of money or any
other matter.

       12.12. Demand Obligations.  Nothing in this Agreement shall affect or
abrogate the demand nature of any portion of the Obligations expressly made
payable on demand by this Agreement or by any instrument evidencing or securing
same, and the occurrence of an Event of Default shall not be a prerequisite for
Lender's requiring payment of such Obligations.

       12.13. Time of Essence.  Time is of the essence of this Agreement and
the Other Agreements.

       12.14. Entire Agreement.  This Agreement and the Other Agreements,

the parties in connection therewith or





LOAN AND SECURITY AGREEMENT - Page 43
<PAGE>   44
with reference thereto, embody the entire understanding and agreement between
the parties hereto and thereto with respect to the subject matter hereof and
thereof and supersede all prior agreements, understandings and inducements,
whether express or implied, oral or written.

       12.15. Interpretation.  No provision of this Agreement or any of the
other Loan Documents shall be construed against or interpreted to the
disadvantage of any party hereto by any court or other governmental or judicial
authority by reason of such party having or being deemed to have structured,
drafted or dictated such provision.

       12.16. Nonapplicability of Article 5069-15.01 et seq.  Borrower and
Lender hereby agree that, except for Section 15.10(b) thereof, the provisions
of Tex. Rev. Civ. Stat. Ann. art. 5069-15.01 et seq. (Vernon 1987) (regulating
certain revolving credit loans and revolving tri-party accounts) shall not
apply to this Agreement or any of the Other Agreements.

       12.17. No Preservation or Marshaling.  Borrower agrees that Lender has
no obligation to preserve rights to the Collateral against prior parties or to

NEGOTIATED, EXECUTED AND DELIVERED AT AND SHALL BE DEEMED TO HAVE BEEN MADE IN
DALLAS, TEXAS.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS; PROVIDED, HOWEVER, THAT IF ANY OF THE
COLLATERAL SHALL BE LOCATED IN ANY JURISDICTION OTHER THAN TEXAS, THE LAWS OF
SUCH JURISDICTION SHALL GOVERN THE METHOD, MANNER AND PROCEDURE FOR FORECLOSURE
OF LENDER'S LIEN UPON SUCH COLLATERAL AND THE ENFORCEMENT OF LENDER'S OTHER
REMEDIES IN RESPECT OF SUCH COLLATERAL TO THE EXTENT THAT THE LAWS OF SUCH
JURISDICTION ARE DIFFERENT FROM OR INCONSISTENT WITH THE LAWS OF TEXAS.  AS
PART OF THE CONSIDERATION FOR NEW VALUE RECEIVED, AND REGARDLESS OF ANY PRESENT
OR FUTURE DOMICILE OR PRINCIPAL PLACE OF BUSINESS OF BORROWER OR LENDER,
BORROWER HEREBY CONSENTS AND AGREES THAT THE DISTRICT COURT OF DALLAS COUNTY,
TEXAS, OR, AT LENDER'S OPTION, THE UNITED STATES DISTRICT COURT FOR THE
NORTHERN DISTRICT OF TEXAS, DALLAS DIVISION, SHALL HAVE EXCLUSIVE JURISDICTION
TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN BORROWER AND LENDER
PERTAINING TO THIS AGREEMENT OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS
AGREEMENT.  BORROWER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BORROWER
HEREBY WAIVES ANY OBJECTION WHICH BORROWER MAY HAVE BASED UPON LACK OF PERSONAL
JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE
GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH
COURT.  BORROWER HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND
OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH

<PAGE>   45
SUMMONS, COMPLAINT AND OTHER PROCESS MAY BE MADE, AT THE ELECTION OF LENDER, BY

EARLIER OF BORROWER'S ACTUAL RECEIPT THEREOF OR FIVE DAYS AFTER DEPOSIT IN THE
U.S. MAILS, PROPER POSTAGE PREPAID; PROVIDED THAT LENDER SHALL ALSO SEND, BY
TELECOPY, TO BORROWER A COPY OF SUCH SUMMONS, COMPLAINT AND OTHER PROCESS (AN
AFFIDAVIT OF AN OFFICER, EMPLOYEE OR AGENT OF LENDER STATING THAT SUCH TELECOPY
WAS SENT TO BORROWER SHALL BE PRESUMPTIVELY CORRECT IN ALL RESPECTS).  NOTHING
IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO AFFECT THE RIGHT OF LENDER TO
SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW, OR TO PRECLUDE THE
ENFORCEMENT BY LENDER OF ANY JUDGMENT OR ORDER OBTAINED IN SUCH FORUM OR THE
TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SAME IN ANY OTHER
APPROPRIATE FORUM OR JURISDICTION.

       12.19. WAIVERS BY BORROWER.  BORROWER WAIVES (A) THE RIGHT TO TRIAL BY
JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT, PROCEEDING OR
COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO ANY OF THE LOAN
DOCUMENTS, THE OBLIGATIONS OR THE COLLATERAL; (B) PRESENTMENT, DEMAND AND
PROTEST AND NOTICE OF PRESENTMENT, PROTEST, DEFAULT, NON-PAYMENT, INTENT TO

WHATEVER LENDER MAY DO IN THIS REGARD; (C) NOTICE PRIOR TO TAKING POSSESSION OR
CONTROL OF THE COLLATERAL OR ANY BOND OR SECURITY WHICH MIGHT BE REQUIRED BY
ANY COURT PRIOR TO ALLOWING LENDER TO EXERCISE ANY OF LENDER'S REMEDIES; (D)
THE BENEFIT OF ALL VALUATION, APPRAISEMENT AND EXEMPTION LAWS; (E) ANY RIGHT
BORROWER MAY HAVE UPON PAYMENT IN FULL OF THE OBLIGATIONS TO REQUIRE LENDER TO
TERMINATE ITS SECURITY INTEREST IN THE COLLATERAL OR IN ANY OTHER PROPERTY OF
BORROWER UNTIL TERMINATION OF THIS AGREEMENT IN ACCORDANCE WITH ITS TERMS AND
THE EXECUTION BY BORROWER, AND BY ANY PERSON WHOSE LOANS TO BORROWER IS USED IN
WHOLE OR IN PART TO SATISFY THE OBLIGATIONS, OF AN AGREEMENT INDEMNIFYING
LENDER FROM ANY LOSS OR DAMAGE LENDER MAY INCUR AS THE RESULT OF DISHONORED
CHECKS OR OTHER ITEMS OF PAYMENT RECEIVED BY LENDER FROM BORROWER OR ANY
ACCOUNT DEBTOR AND APPLIED TO THE OBLIGATIONS; AND (F) NOTICE OF ACCEPTANCE
HEREOF.  BORROWER ACKNOWLEDGES THAT THE FOREGOING WAIVERS ARE A MATERIAL
INDUCEMENT TO LENDER'S ENTERING INTO THIS AGREEMENT AND THAT LENDER IS RELYING
UPON THE FOREGOING WAIVERS IN ITS FUTURE DEALINGS WITH BORROWER.  BORROWER
WARRANTS AND REPRESENTS THAT IT HAS





LOAN AND SECURITY AGREEMENT - Page 45
<PAGE>   46
REVIEWED THE FOREGOING WAIVERS WITH ITS LEGAL COUNSEL AND HAS KNOWINGLY AND
VOLUNTARILY WAIVED ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL
COUNSEL.  IN THE EVENT OF LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN
CONSENT TO A TRIAL BY THE COURT.

       12.20. SPECIAL LOUISIANA PROVISIONS.  Insofar as the validity or
perfection of the security interest hereunder or the remedies hereunder are
governed by the laws of the State of Louisiana, Borrower agrees as follows:

              (i)    For purposes of Louisiana executory process, Borrower
       acknowledges the Obligations secured hereby, whether now existing or to
       arise hereafter, and confesses judgment thereon if not paid when due.
       Upon the occurrence of an Event of Default and at any time thereafter so
       long as the same shall be continuing, and in addition to all of the
       rights and remedies granted the Lender hereunder, it shall be lawful for
       and Borrower hereby authorizes Lender without making a demand or putting
       Borrower in default, a putting in default being expressly waived, to
       cause all and singular the Collateral to be seized and sold after due
       process of law, Borrower waiving the benefit of any and all laws or
       parts of laws relative to appraisement of property seized and sold under
       executory process or other legal process, and consenting that the
       Collateral be sold without appraisement, either in its entirety or in
       lots or parcels, as Lender may determine, to the highest bidder for cash
       or on such other terms as the plaintiff in such proceedings may direct.
       In addition, Lender shall have all of the-rights and remedies available
       to it under this Agreement or under the Louisiana Commercial Laws
       (Louisiana Revised Statutes, Title 10), then in effect (La. R.S. 10:9-
       101 et seq.).

              (ii)   Borrower hereby waives:

              (a)    the benefit of appraisement provided       for in Articles
                     2332, 2336, 2723 and 2724 of the Louisiana Code of Civil
                     Procedure and all other laws conferring the same;

              (b)    the demand and three (3) days notice of demand as provided
                     in Articles 2639 and 2721 of the Louisiana Code of Civil
                     Procedure;

              (c)    the notice of seizure provided by Articles 2293 and 2721
                     of the Louisiana Code of Civil Procedure; and

              (d)    the three (3) day delay provided for in Articles 2331 and
                     2722 of the Louisiana Code of Civil Procedure.

              (iii)  Borrower expressly authorizes and agrees that Lender shall
       have the right to appoint a keeper of the Collateral pursuant to the
       terms and provision of La. R.S. 9:5136.

       12.22  WAIVER OF CONSUMER RIGHTS.  BORROWER HEREBY WAIVES ITS RIGHTS
UNDER THE TEXAS DECEPTIVE TRADE PRACTICES--CONSUMER PROTECTION ACT SECTION

SPECIAL RIGHTS AND PROTECTIONS.  AFTER CONSULTATION WITH AN ATTORNEY OF
BORROWER'S OWN SELECTION, BORROWER VOLUNTARILY CONSENTS TO THIS WAIVER.
BORROWER EXPRESSLY WARRANTS AND REPRESENTS THAT BORROWER (i) IS NOT IN A
SIGNIFICANTLY DISPARATE BARGAINING POSITION RELATIVE TO LENDER, AND (ii) HAS
BEEN REPRESENTED BY LEGAL COUNSEL IN CONNECTION WITH THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT.

                        CONTINUING GUARANTY AGREEMENT
             [Indebtedness of Pelican State Supply Company, Inc. -
                             DXP Enterprises, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of PELICAN STATE
SUPPLY COMPANY, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or replaced
from time to time; (ii) any document executed in connection with or as security
for payment of the Obligations or any renewal, extension, or modification
thereof; and (iii) all costs, attorneys' fees, and other expenses incurred by
Lender by reason of any default by Borrower under any of the foregoing (all of
the foregoing are hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other




                                      1
<PAGE>   2
liability or obligation to Lender, whether the same is incurred through the
execution of a note, a similar guaranty, through endorsement, or otherwise; and
acknowledges that neither Lender nor any officer, employee, agent, attorney or
other representative of Lender has made any representation, warranty or
statement to Guarantor to induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no





                                       2

duty to advise Guarantor of information known to Lender regarding such
condition or any such circumstances.  Guarantor is not relying on the financial
condition of Borrower or the value of any collateral for the Obligations as an
inducement to enter into this Guaranty.  If Lender, in its sole discretion,
undertakes at any time or from time to time to provide any such information to
Guarantor, Lender shall be under no obligation (i) to undertake any
investigation not a part of its regular business routine, (ii) to disclose any
information which, pursuant to accepted or reasonable commercial finance
practices, Lender wishes to maintain confidential, or (iii) to make any other
or future disclosures of such information or any other information to
Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of





                                       3
<PAGE>   4
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the Maximum Legal Rate ("Excess"), Guarantor
acknowledges and stipulates that any such charge or collection shall be the
result of an accident and bona fide error, and such Excess shall be, first,
applied to reduce the Obligations; and second, returned to Guarantor, it being
the intention of the parties hereto not to enter at any time into a usurious or
otherwise illegal relationship.  Guarantor recognizes that, with fluctuations
in the applicable rate on the Obligations and the Maximum Legal Rate, such an
unintentional result could inadvertently occur.  By the execution of this
Guaranty, Guarantor covenants that Guarantor shall not seek or pursue any other
remedy, legal or equitable, against Lender, based in whole or in part upon the
contracting, charging or receiving of any interest in excess of the maximum
authorized by applicable law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

       THIS WRITTEN GUARANTY, TOGETHER WITH ALL OTHER INSTRUMENTS, AGREEMENTS
AND CERTIFICATES EXECUTED BY THE PARTIES IN CONNECTION WITH THE OBLIGATIONS OR
WITH REFERENCE HERETO OR THERETO, REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR

AGREEMENTS BETWEEN THE PARTIES.

                         CONTINUING GUARANTY AGREEMENT
 [Indebtedness of Pelican State Supply Company, Inc. - Sepco Industries, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of PELICAN STATE
SUPPLY COMPANY, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time; (ii) any document executed in connection with or as security
for payment of the Obligations or any renewal, extension, or modification
thereof; and (iii) all costs, attorneys' fees, and other expenses incurred by
Lender by reason of any default by Borrower under any of the foregoing (all of
the foregoing are hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees that Guarantor's contingent
obligations under this Guaranty constitute "Obligations" as such term is
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, executed by Lender and Guarantor, as
renewed, extended, modified and restated from time to time.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

                         CONTINUING GUARANTY AGREEMENT
   [Indebtedness of Pelican State Supply Company, Inc. - American MRO, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of PELICAN STATE
SUPPLY COMPANY, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time; (ii) any document executed in connection with or as security
for payment of the Obligations or any renewal, extension, or modification
thereof; and (iii) all costs, attorneys' fees, and other expenses incurred by
Lender by reason of any default by Borrower under any of the foregoing (all of
the foregoing are hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees that Guarantor's contingent
obligations under this Guaranty constitute "Obligations" as such term is
defined in that certain Loan and Security Agreement, dated as of the date
hereof, executed by Lender and Sepco Industries, Inc., as renewed, extended,
modified and restated from time to time.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

                        CONTINUING GUARANTY AGREEMENT
    [Indebtedness of Pelican State Supply Company, Inc. - Bayou Pumps, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of PELICAN STATE
SUPPLY COMPANY, INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Loan and Security Agreement, dated on or about the date
hereof, between Lender and Borrower, as renewed, extended, modified or restated
from time to time; (ii) any document executed in connection with or as security
for payment of the Obligations or any renewal, extension, or modification
thereof; and (iii) all costs, attorneys' fees, and other expenses incurred by
Lender by reason of any default by Borrower under any of the foregoing (all of
the foregoing are hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees that Guarantor's contingent
obligations under this Guaranty constitute "Obligations" as such term is
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, executed by Lender and Sepco Industries,
Inc., as renewed, extended, modified and restated from time to time.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

                         CONTINUING GUARANTY AGREEMENT
 [Indebtedness of Sepco Industries, Inc. - Pelican State Supply Company, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of SEPCO INDUSTRIES,
INC., a Texas corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, between Lender and Borrower, as renewed,
extended, modified or restated from time to time; (ii) any document executed in
connection with or as security for payment of the Obligations or any renewal,
extension, or modification thereof; and (iii) all costs, attorneys' fees, and
other expenses incurred by Lender by reason of any default by Borrower under
any of the foregoing (all of the foregoing are hereinafter referred to as the
"Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees that Guarantor's contingent
obligations under this Guaranty constitute "Obligations" as such term is
defined in that certain Loan and Security Agreement, dated as of the date
hereof, executed by Lender and Guarantor, as renewed, extended, modified and
restated from time to time.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

                         CONTINUING GUARANTY AGREEMENT
   [Indebtedness of American MRO, Inc. - Pelican State Supply Company, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of AMERICAN MRO,
INC., a Nevada corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, between Lender and Sepco Industries,
Inc., as renewed, extended, modified or restated from time to time; (ii) any
document executed in connection with or as security for payment of the

hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent
conveyance laws.  Accordingly, the term "Maximum Guaranteed Amount" shall mean
ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees that Guarantor's contingent
obligations under this Guaranty constitute "Obligations" as such term is
defined in that certain Loan and Security Agreement, dated as of the date
hereof, executed by Lender and Guarantor, as renewed, extended, modified and
restated from time to time.

       THIS GUARANTY HAS BEEN NEGOTIATED AND SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF TEXAS.  THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF
CONFLICTS OF THE STATE OF TEXAS.  AS PART OF THE CONSIDERATION FOR NEW VALUE
AND BENEFIT THIS DAY RECEIVED BY GUARANTOR, GUARANTOR HEREBY CONSENTS TO THE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED
MAIL DIRECTED TO GUARANTOR AT THE ADDRESS STATED HEREIN AND SERVICE SO MADE
SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF.  GUARANTOR WAIVES
ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
GUARANTY OR THE OBLIGATIONS.

                         CONTINUING GUARANTY AGREEMENT
    [Indebtedness of Bayou Pumps, Inc. - Pelican State Supply Company, Inc.]

       FOR VALUE RECEIVED the undersigned (hereinafter referred to as
"Guarantor") guarantees unconditionally the full and prompt payment to FLEET
CAPITAL CORPORATION ("Lender"), at Lender's office in Dallas County, Texas,
upon demand, of the following obligations and indebtedness of BAYOU PUMPS,
INC., a Texas corporation ("Borrower"):

Any and all indebtedness and obligations, whether direct or indirect, absolute
or contingent, primary or secondary, joint or several, and all renewals,
modifications and extensions thereof for which Borrower, is now, or hereafter
may become liable or indebted to Lender, whether arising by loan agreements,
notes, drafts, acceptances, letters of credit, overdrafts, assignments,
participations, discounts or otherwise, and all interest accruing thereon
(including, without limitation, interest which would accrue but for the
commencement of a bankruptcy proceeding), fees charged in connection therewith
and reimbursable expenses incurred in connection therewith, whether by lapse of
time, acceleration of maturity, or otherwise, including such indebtedness and
obligations now or hereafter arising on account of (i) the Obligations, as
defined in that certain Second Amended and Restated Loan and Security
Agreement, dated as of April 1, 1994, between Lender and Sepco Industries,
Inc., as renewed, extended, modified or restated from time to time; (ii) any
document executed in connection with or as security for payment of the
Obligations or any renewal, extension, or modification thereof; and (iii) all
costs, attorneys' fees, and other expenses incurred by Lender by reason of any
default by Borrower under any of the foregoing (all of the foregoing are
hereinafter referred to as the "Obligations").

       At the time Guarantor pays any sum which may become due Lender under the
terms of this Guaranty, written notice of such payment shall be delivered to
Lender by Guarantor, and in the absence of such notice, any sum received by
Lender on account of any of the Obligations shall be conclusively deemed paid
by Borrower.  All sums paid Lender by Guarantor may be applied by Lender at its
discretion upon any of the Obligations.  To further secure payment of the
Obligations, Guarantor grants to Lender, in addition to all other contractual,
legal, and equitable rights of Lender, the right to offset against any account,
certificate of deposit, or other funds of Guarantor in the possession of or
under the control of Lender.

       Guarantor hereby waives notice of acceptance of this Guaranty and all
other notices in connection herewith or in connection with the Obligations,
including without limitation, notice of intent to accelerate and notice of
acceleration, and waives diligence, presentment, demand, protest, and suit on
the part of Lender in the collection of any of the Obligations, and agrees that
Lender shall not be required to first endeavor to collect any of the
Obligations from Borrower, or any other party liable for payment of the
Obligations (hereinafter referred to as an "Obligated Party"), before requiring
Guarantor to pay the full amount of the Obligations.  Without impairing the
rights of Lender against Guarantor, any Obligated Party or Borrower, suit may
be brought and maintained against Guarantor at the election of Lender with or
without joinder of Borrower or any Obligated Party, any right to any such
joinder being hereby waived by Guarantor.

       Guarantor represents to Lender it is receiving a direct and/or indirect
benefit as a result of this Guaranty and the Obligations; represents to Lender
that after giving effect to this Guaranty and the contingent obligations
evidenced hereby it is, and will be, solvent; acknowledges that this Guaranty
is operative and binding as to it without reference to whether it is signed by
a person under any legal disability; acknowledges that its liability hereunder
shall be cumulative and in addition to any other liability or obligation to
Lender, whether the same is incurred through the execution of a note, a similar




                                      1
<PAGE>   2
guaranty, through endorsement, or otherwise; and acknowledges that neither
Lender nor any officer, employee, agent, attorney or other representative of
Lender has made any representation, warranty or statement to Guarantor to
induce it to execute this Guaranty.

       Guarantor hereby agrees that, except as hereinafter provided, its
obligations under this Guaranty shall be continuing, absolute and
unconditional, irrespective of (i) the validity or enforceability of the
Obligations or of any promissory note or other document evidencing all or any
part of the Obligations, (ii) the absence of any attempt to collect the
Obligations from Borrower or any other Obligated Party or other action to
enforce the same, (iii) the waiver or amendment by Lender with respect to any
provision of any instrument evidencing the Obligations, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to
Lender, (iv) failure by Lender to take any steps to perfect and maintain its
security interest in, or to preserve its rights to, any security or collateral
for the Obligations, (v) the surrender, release, exchange, or alteration by
Lender of any security or collateral for the Obligations, (vi) Lender's
election, in any proceeding instituted under Chapter 11 of Title 11 of the
United States Code (11 U.S.C Section 101 et seq.) (the "Bankruptcy Code"), of
the application of Section 1111(b)(2) of the Bankruptcy Code,  (vii) any
borrowing or grant of a security interest by Borrower, as debtor-in-possession,
under Section 364 of the Bankruptcy Code, (viii) the disallowance of all or any
portion of Lender's claim(s) for repayment of the Obligations under Section 502
of the Bankruptcy Code, or (ix) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

       No release, waiver, or discharge of Borrower or any Obligated Party from
liability for payment of any of the Obligations nor any renewal,
supplementation, modification, rearrangement or acceleration of any of the
Obligations, nor any amendment of any document evidencing any of the
Obligations, either express or implied, shall relieve Guarantor from liability
for payment of the full amount of the Obligations then or thereafter
outstanding; and Guarantor will immediately pay all Obligations to Lender or
other person entitled thereto, regardless of any defense (other than payment),
right of set-off, or counterclaim which Borrower or any Obligated Party may
have or assert, and regardless of whether Lender or any other party shall have
taken any steps to enforce any rights against Borrower, any Obligated Party, or
any other party to collect such sum, and regardless of any other condition or
contingency, including, without limitation, any neglect, delay, or omission of
Lender.  Lender is hereby authorized, without notice or demand and without
affecting the liability of Guarantor, to, from time to time: (i) accept partial
payments on the Obligations; (ii) take and hold security or collateral for the
payment of this Guaranty or any other guarantees of the Obligations, and
exchange, enforce, waive and release any such security or collateral; and (iii)
apply such security or collateral therefor in any manner, without affecting or
impairing the obligations of Guarantor hereunder.

       Notwithstanding anything to the contrary contained herein, Guarantor
shall not have any right, claim or action, now or hereafter, against Borrower
or any other Obligated Party arising out of or in connection with this Guaranty
or any other document evidencing or securing the Obligations, including,
without limitation, any right or claim of subrogation, contribution,
reimbursement, exoneration, or indemnity, all such rights and claims being
hereby expressly and absolutely waived.

       Guarantor is familiar with, and has independently reviewed the financial
condition of, Borrower and hereby assumes responsibility for keeping itself
informed of the financial condition of Borrower, and any and all endorsers
and/or other guarantors of any instrument or document evidencing all or any
part of the Obligations and of all other circumstances bearing upon the risk of
nonpayment of the  Obligations or any part thereof that diligent inquiry would
reveal.  Guarantor hereby agrees that Lender shall have no duty to advise
Guarantor of information known to Lender regarding such condition or any such





                                       2
<PAGE>   3
circumstances.  Guarantor is not relying on the financial condition of Borrower
or the value of any collateral for the Obligations as an inducement to enter
into this Guaranty.  If Lender, in its sole discretion, undertakes at any time
or from time to time to provide any such information to Guarantor, Lender shall
be under no obligation (i) to undertake any investigation not a part of its
regular business routine, (ii) to disclose any information which, pursuant to
accepted or reasonable commercial finance practices, Lender wishes to maintain
confidential, or (iii) to make any other or future disclosures of such
information or any other information to Guarantor.

       Guarantor consents and agrees that Lender shall be under no obligation
to marshal any assets in favor of Guarantor or against or in payment of any or
all of the Obligations.  Guarantor further agrees that, to the extent that
Borrower makes a payment or payments to Lender, or Lender receives any proceeds
of collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to Borrower, any of their respective estates, trustees,
receivers or any other party, including, without limitation, Guarantor, under
any bankruptcy law, state or federal law, common law or equitable cause, then
to the extent of such payment or repayment, the Obligations or part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated
and continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred, and this Guaranty, if previously
terminated, shall be reinstated for the benefit of Lender.

       Lender may assign its rights hereunder to any holder of the Obligations,
in whole or in part, and upon any such assignment all the terms and provisions
of this Guaranty shall inure to the benefit of such assignee, to the extent so
assigned.

       Lender is relying and is entitled to rely upon each and all of the
provisions of this Guaranty; and, accordingly, if any provision of this
Guaranty should be held to be invalid or ineffective, then all other provisions
shall continue in full force and effect notwithstanding.

       Any and all notices, requests and demands to or upon Guarantor to be
effective shall be in writing, and shall be sent by certified or registered
mail, return receipt requested, personal receipt against delivery, or by
telegraph or telex and, unless otherwise expressly provided herein,  shall be
deemed to have been validly served, given or delivered when delivered against
receipt or three business days after deposit in the mail, postage prepaid, or,
in the case of telegraphic notice, when delivered to the telegraph company, or,
in the case of telex notice, when sent, answerback received, addressed to the
address set forth opposite Guarantor's signature below.

       It is the intention of Borrower, Guarantor and Lender to conform
strictly to applicable usury laws.  Accordingly, no agreements, conditions,
provisions or stipulations contained in this Guaranty or any other instrument,
document or agreement between Guarantor or Borrower and Lender or default of
Guarantor or Borrower, or the exercise by Lender of the right to accelerate the
payment of the maturity of principal and interest, or to exercise any option
whatsoever contained in this Guaranty or any other agreement between Guarantor
or Borrower and Lender, or the arising of any contingency whatsoever, shall
entitle Lender to charge or collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and
all agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is charged or
collected in excess of the





                                       3
<PAGE>   4
Maximum Legal Rate ("Excess"), Guarantor acknowledges and stipulates that any
such charge or collection shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the Obligations; and
second, returned to Guarantor, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Guarantor recognizes that, with fluctuations in the applicable rate on the
Obligations and the Maximum Legal Rate, such an unintentional result could
inadvertently occur.  By the execution of this Guaranty, Guarantor covenants
that Guarantor shall not seek or pursue any other remedy, legal or equitable,
against Lender, based in whole or in part upon the contracting, charging or
receiving of any interest in excess of the maximum authorized by applicable
law.

       If any sum due Lender by Guarantor hereunder is placed in the hands of
an attorney for collection, or is collected through probate, bankruptcy, or
other court proceeding, then Guarantor promises to pay Lender all reasonable
costs, attorneys' fees, and other expenses incurred by Lender pursuant to such
collection efforts.

       It is understood that while the amount of credit which may be extended
to Borrower and the amount of Obligations which may be incurred by Borrower are
not limited, Guarantor's liability hereunder shall be limited to the "Maximum
Guaranteed Amount" (as hereinafter defined).  It is the intention of Lender and
Guarantor that Guarantor's obligations hereunder be in all respects in
compliance with, and not be voidable pursuant to, applicable fraudulent

ninety-five percent (95%) of the maximum obligation, if any, which could have
been incurred by Guarantor without being voidable as a fraudulent transfer or
conveyance, and shall be determined as of the date any "transfer" or
"conveyance" is made by Guarantor hereunder pursuant to applicable law.

       Guarantor acknowledges and agrees that Guarantor's contingent
obligations under this Guaranty constitute "Obligations" as such term is
defined in that certain Loan and Security Agreement, dated as of the date
hereof, executed by Lender and Guarantor, as renewed, extended, modified and
restated from time to time.

ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS AND NOT THE LAWS OF

JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN DALLAS COUNTY OF THE
STATE OF TEXAS AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND
CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED

ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE.

       EXCEPT AS OTHERWISE PROVIDED FOR IN THIS GUARANTY, GUARANTOR WAIVES THE
RIGHT TO TRIAL BY JURY (WHICH LENDER HEREBY ALSO WAIVES) IN ANY ACTION, SUIT,
PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS
