                                    RECITALS:

A. Lender and Technical Products, Marion, DeLand and Lincoln (collectively, the
"ORIGINAL BORROWERS") have entered into that certain Loan and Security Agreement
dated December 27, 1996, as amended by that certain First Amendment to Loan and
Security Agreement dated as of June 10, 1997, and as further amended by that
certain Second Amendment to Loan and Security Agreement dated as of October 31,
1997 (as amended, the "ORIGINAL LOAN AGREEMENT").

B. Lender and Borrower desire to amend, restate and modify (but not extinguish)
the Original Loan Agreement and the other Original Loan Documents as hereinafter
set forth to (i) add ATP and Alcore as borrowers hereunder and allow and provide
for the extension of loans and advances to ATP and Alcore hereunder, and (ii)
allow and provide for certain other matters as hereinafter set forth.

      NOW, THEREFORE, for and in consideration of the mutual covenants set forth
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, Lender and Borrower covenant and agree as follows:

SECTION 1.  CREDIT FACILITY

      Subject to the terms and conditions of, and in reliance upon the
representations and warranties made in, this Agreement and the other Loan
Documents, Lender agrees to make a total credit facility of up to $48,000,000
available upon Borrower's request therefor, as follows:

                                       1
<PAGE>
      1.1   REVOLVING CREDIT LOANS.

            1.1.1 LOANS AND RESERVES. Lender agrees, during the term of this
Agreement and for so long as no Default or Event of Default exists, to make
Revolving Credit Loans to Revolving Credit Borrowers from time to time, as
requested by Borrower in the manner set forth in SECTION 3.1.1 hereof, up to a
maximum principal amount at any time outstanding equal to the Borrowing Base at
such time MINUS the LC Amount and reserves, if any. Lender shall have the right
to establish reserves in such amounts, and with respect to such matters, as
Lender shall deem necessary or appropriate, against the amount of Revolving
Credit Loans which Revolving Credit Borrower may otherwise request under this
SECTION 1.1, including, without limitation, with respect to (i) price
adjustments, damages, unearned discounts, returned products or other matters for
which credit memoranda are issued in the ordinary course of Revolving Credit
Borrowers' business; (ii) obsolescence of Inventory; (iii) slow moving
Inventory; (iv) other sums chargeable against Borrower's Loan Account as
Revolving Credit Loans under any section of this Agreement; (v) amounts owing by
Borrower to any Person to the extent secured by a Lien on, or trust over, any
Property of Borrower; (vi) all amounts of past due rent or other charges owing
at such time by Borrower to any Landlord of any premises where any of the
Collateral is located; and (vii) such other matters, events, conditions or
contingencies as to which Lender, in its reasonable judgment, determines
reserves should be established from time to time hereunder.

            1.1.2 USE OF PROCEEDS. The Revolving Credit Loans shall be used
solely for the satisfaction of existing Indebtedness of Borrower to Brunswick
and First Union National Bank, for the repayment of the Obligations, and for
Borrower's general operating capital needs in a manner consistent with the
provisions of this Agreement and Applicable Law. In no event shall any proceeds
of any Revolving Credit Loans be used to purchase or to carry, reduce, retire or
refinance any Indebtedness incurred to purchase or carry any margin stock
(within the meaning of Regulations G or U of the Federal Reserve Board).

      1.2.  TERM AND EQUIPMENT LOANS.

            1.2.1 TERM LOAN. Borrower hereby represents and warrants that, on
December 27, 1996, Lender made a term loan to Original Borrowers in the
principal amount of $14,000,000 ("ORIGINAL TERM LOAN"), which Original Term Loan
is repayable in accordance with the terms of the Original Term Note and is
secured by all of the Collateral. Borrower further represents and warrants that,
as of the date of this Agreement, the unpaid principal balance of the Original
Term Loan is $12,000,000, and such amount is unconditionally owed by Original
Borrowers to Lender without offset, defense or counterclaim of any kind, nature
or description whatsoever. Subject to the terms of this Agreement, Lender agrees
to make an additional term loan to Borrower on the Closing Date in the principal
amount of $6,000,000, which additional term loan shall be combined with the
Original Term Loan into a single term loan of $18,000,000 ("TERM LOAN"). 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 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.

                                       2
<PAGE>
            1.2.2 EQUIPMENT LOANS. Lender agrees, during the term of this
Agreement, for so long as no Default or Event of Default exists, to make Loans
("EQUIPMENT LOANS") to Borrower from time to time, to finance Borrower's
purchases of Equipment for use in its business. Each Equipment Loan shall be in
the aggregate principal amount of not less than $250,000, and shall not exceed
80% of the invoiced purchase price (excluding taxes, title, freight, and
installation costs) of the Equipment being acquired with the proceeds of such
Equipment Loan. Each Equipment Loan shall be secured by all of the Collateral
and shall be evidenced by the Equipment Note, which Equipment Note shall specify
the rate of interest and the repayment terms applicable to such Equipment Loan.
The principal amount of Equipment Loans hereunder shall not exceed, in the
aggregate, $3,000,000. Borrower may not reborrow any amount repaid with respect
to any Equipment Loan.

      1.3 LETTERS OF CREDIT; LC GUARANTIES. Lender agrees, for so long as no
Default or Event of Default exists and if requested by Borrower, to (i) issue
its, or cause to be issued its Affiliate's, standby Letters of Credit for the
account of Revolving Credit Borrowers or (ii) execute LC Guaranties by which
Lender or its Affiliate shall guaranty the payment or performance by Revolving
Credit Borrowers of their reimbursement obligations with respect to standby
Letters of Credit, provided that the LC Amount at any time shall not exceed
$2,000,000. No Letter of Credit or LC Guarantee shall have an expiration date
that is after the last day of the Original Term or the then applicable Renewal
Term. Any amounts paid by Lender under any LC Guaranty or in connection with any
Letter of Credit shall be treated as Revolving Credit Loans, shall be secured by
all of the Collateral and shall bear interest and be payable at the same rate
and in the same manner as Revolving Credit Loans.

      1.4 ALL LOANS TO CONSTITUTE ONE OBLIGATION. All Loans shall constitute one
general joint and several obligation of Borrowers, 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.

      1.5   JOINT AND SEVERAL LIABILITY; RIGHTS OF CONTRIBUTION.

            (A) Each Borrower states and acknowledges that: (i) pursuant to this
Agreement, Borrowers desire to utilize their borrowing potential on a
consolidated basis to the same extent possible if they were merged into a single
corporate entity and that this Agreement reflects the establishment of credit
facilities which would not otherwise be available to such Borrower if each
Borrower were not jointly and severally liable for payment of all of the
Obligations; (ii) it has determined that it will benefit specifically and
materially from the advances of credit contemplated by this Agreement; (iii) it
is both a condition precedent to the obligations of Lender hereunder and a
desire of the Borrowers that each Borrower execute and deliver to Lender this
Agreement; and (iv) Borrowers have requested and bargained for the structure and
terms of and security for the advances contemplated by this Agreement.

            (B) Each Borrower hereby irrevocably and unconditionally: (i) agrees
that it is jointly and severally liable to Lender for the full and prompt
payment of the Obligations and the performance by each Borrower of its
obligations hereunder in accordance with the terms hereof; 

                                       3
<PAGE>
(ii) agrees to fully and promptly perform all of its obligations hereunder with
respect to each advance of credit hereunder as if such advance had been made
directly to it; and (iii) agrees as a primary obligation to indemnify Lender on
demand for and against any loss incurred by Lender as a result of any of the
obligations of any one or more of the Borrowers being or becoming void,
voidable, unenforceable or ineffective for any reason whatsoever, whether or not
known to Lender or any Person, the amount of such loss being the amount which
Lender would otherwise have been entitled to recover from any one or more of the
Borrowers.

            (C) It is the intent of each Borrower that the indebtedness,
obligations and liability hereunder of no one of them be subject to challenge on
any basis, including, without limitation, pursuant to any applicable fraudulent
conveyance or fraudulent transfer laws. Accordingly, as of the date hereof, the
liability of each Borrower under this SECTION 1.5, together with all of its
other liabilities to all Persons as of the date hereof and as of any other date
on which a transfer or conveyance is deemed to occur by virtue of this
Agreement, calculated in amount sufficient to pay its probable net liabilities
on its existing Indebtedness as the same become absolute and matured ("DATED
LIABILITIES") is, and is to be, less than the amount of the aggregate of a fair
valuation of its property as of such corresponding date ("DATED ASSETS"). To
this end, each Borrower under this SECTION 1.5, (i) grants to and recognizes in
each other Borrower, ratably, rights of subrogation and contribution in the
amount, if any, by which the Dated Assets of such Borrower, but for the
aggregate of subrogation and contribution in its favor recognized herein, would
exceed the Dated Liabilities of such Borrower or, as the case may be, (ii)
acknowledges receipt of and recognizes its right to subrogation and contribution
ratably from each of the other Borrowers in the amount, if any, by which the
Dated Liabilities of such Borrower, but for the aggregate of subrogation and
contribution in its favor recognized herein, would exceed the Dated Assets of
such Borrower under this SECTION 1.5. In recognizing the value of the Dated
Assets and the Dated Liabilities, it is understood that Borrowers will
recognize, to at least the same extent of their aggregate recognition of
liabilities hereunder, their rights to subrogation and contribution hereunder.
It is a material objective of this SECTION 1.5 that each Borrower recognizes
rights to subrogation and contribution rather than be deemed to be insolvent (or
in contemplation thereof) by reason of an arbitrary interpretation of its joint
and several obligations hereunder. In addition to and not in limitation of the
foregoing provisions of this SECTION 1.5, the Borrowers and Lender hereby agree
and acknowledge that it is the intent of each Borrower and of Lender that the
obligations of each Borrower hereunder be in all respects in compliance with,
and not be voidable pursuant to, applicable fraudulent conveyance and fraudulent
transfer laws.

      1.6 STRUCTURE OF CREDIT FACILITY. Each Borrower agrees and acknowledges
that the present structure of the credit facilities detailed in this Agreement
is based in part upon the financial and other information presently known to
Lender regarding each Borrower, the corporate structure of Borrowers, and the
present financial condition of each Borrower. Each Borrower hereby agrees that
Lender shall have the right, in its sole credit judgment, to require that any or
all of the following changes be made to these credit facilities: (i) restrict
loans and advances between Borrowers, (ii) establish separate lockbox and
dominion accounts for Revolving Credit Borrowers and, upon and after the
occurrence of a Default or Event of Default, for each other Borrower, (iii)
separate the Term Loan into separate term loans to such of the 

                                       4
<PAGE>
Borrowers as shall be determined by Lender, and (iv) establish such other
procedures as shall be reasonably deemed by Lender to be useful in tracking
where Loans are made under this Agreement and the source of payments received by
Lender on such Loans.

      1.7 ORIGINAL BORROWERS. Notwithstanding any other provision of the Term
Note or this Agreement to the contrary, it is hereby agreed that New Borrowers
are not assuming payment of the unpaid principal balance of the Obligations
which was incurred by Original Borrowers prior to the Closing Date pursuant to
the Original Loan Documents (the "ORIGINAL BORROWER OBLIGATIONS"). However the
parties hereto agree and acknowledge that the preceding sentence shall not (A)
limit any contingent liability of New Borrowers for payment of any of the
Original Borrower Obligations which arises pursuant to the Guaranty Agreements
to be executed on the Closing Date by New Borrowers, or (B) limit the Liens in
favor of Lender granted by New Borrowers against the assets of New Borrowers as
a result of New Borrowers becoming an additional named "Borrower", which Liens
shall secure payment of all Obligations arising in connection with this
Agreement, whether currently existing or hereafter arising. For purposes of
determining on or after the date hereof which Obligations outstanding constitute
Original Borrower Obligations, all payments received by Lender from Original
Borrowers on account of the Obligations shall be deemed to be applied first in
payment of the Original Borrower Obligations until such time as the Original
Borrower Obligations shall have been reduced to zero, and thereafter to the
other Obligations as hereinafter set forth.

SECTION 2.  INTEREST,  FEES  AND  CHARGES

      2.1.  INTEREST.

            2.1.1. RATES OF INTEREST. The outstanding principal amount of the
Loans shall bear interest at the following rates per annum (individually called,
as applicable, an "APPLICABLE ANNUAL RATE"): (i) FOR REVOLVING CREDIT LOANS, (a)
each Eurodollar Loan shall bear interest at a rate per annum equal to LIBOR PLUS
the Applicable Margin then in effect for the LIBOR Interest Period applicable
thereto, and (b) each Base Rate Loan shall bear interest at a rate per annum
equal to the Base Rate PLUS one-quarter of one percent (0.25%), and (ii) FOR THE
TERM LOAN AND EACH EQUIPMENT LOAN, (a) each Eurodollar Loan shall bear interest
at a rate per annum equal to LIBOR PLUS the Applicable Margin then in effect for
the LIBOR Interest Period applicable thereto, and (b) each Base Rate Loan shall
bear interest at a rate per annum equal to the Base Rate PLUS one-half of one
percent (0.50%). Unless Borrower delivers a Borrowing Notice to Lender in
accordance with SECTION 3.1.1(A) hereof irrevocably electing that all or any
portion of the Loans are to bear interest at a rate based upon LIBOR, all of the
Loans shall bear interest at a rate based upon the Base Rate as provided in
CLAUSES (I)(B) and (II)(B) of this SECTION 2.1.1. The rate of interest
applicable to Base Rate Loans shall increase or decrease by an amount equal to
any increase or decrease in the Base Rate, effective as of the opening of
business on the day that any such change in the Base Rate occurs.

            2.1.2. DEFAULT RATE OF INTEREST. Upon and after the occurrence of an
Event of Default, and during the continuation thereof, the principal amount of
all Loans shall, in Lender's 

                                       5
<PAGE>
sole discretion, bear interest at a rate per annum equal to 2.00% above the
Applicable Annual Rate or other interest rate otherwise applicable thereto (the
"DEFAULT RATE").

            2.1.3 MAXIMUM INTEREST. (A) Notwithstanding anything to the contrary
in this Agreement or otherwise, (i) if at any time the amount of interest
computed on the basis of an Applicable Annual Rate or a 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 such 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 an Applicable Annual Rate or Default
Rate, as applicable; and (ii) unless preempted by federal law, an Applicable
Annual Rate or Default Rate, as applicable, from time to time in effect
hereunder may not exceed the "weekly ceiling" from time to time in effect under
Chapter 303 of the Texas Finance Code. 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 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 in
accordance with SECTION 3.2.2 hereof.

                  (B) EXCESS INTEREST. 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 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
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 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 Interest shall constitute the acceptance by Borrower of such Excess
Interest, and (ii) Borrower shall not seek or pursue any 

                                       6
<PAGE>
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.

                  (C) INCORPORATION BY THIS REFERENCE. The provisions of SECTION
2.1.3(B) 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 2.1.3(B) 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 Borrowers (or other obligor)
asserted by Lender thereunder, be automatically re-computed by any Borrower or
obligor, and by any court considering the same, to give effect to the
adjustments or credits required by SECTION 2.1.3(B).

      2.2. COMPUTATION OF INTEREST AND FEES. Interest, Letter of Credit and LC
Guaranty Fees and unused line fees hereunder shall be calculated daily and shall
be computed on the actual number of days elapsed over a year of 360 days. 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 item of payment on the date specified in SECTION
3.4 hereof.

      2.3. CLOSING FEE. Borrower shall pay to Lender a closing fee of $80,000,
which shall be fully earned and (except to the extent otherwise required by
Applicable Law) nonrefundable on the Closing Date, and shall be paid
concurrently with the initial Loan hereunder.

      2.4 LETTER OF CREDIT AND LC GUARANTY FEES. Borrower shall pay to Lender
for standby Letters of Credit and LC Guaranties of standby Letters of Credit,
one and one-half percent (1.50%) per annum of the aggregate face amount of such
Letters of Credit and LC Guaranties outstanding from time to time during the
term of this Agreement, plus all normal and customary charges associated with
issuance thereof, which fees and charges shall be deemed fully earned upon
issuance of each such Letter of Credit or LC Guaranty, shall be due and payable
on the first Business Day of each month and shall not be subject to rebate or
proration upon the termination of this Agreement for any reason.

      2.5. UNUSED LINE FEE. Borrower shall pay to Lender a fee equal to one-half
of one percent (0.50%) per annum of the amount by which the Average Monthly
Revolving Credit Loan Balance is less than the Total Revolving Credit Facility.
The unused line fee shall be payable monthly, in arrears, on the first day of
each calendar month hereafter.

                                       7
<PAGE>
      2.6. AUDIT AND APPRAISAL FEES. Borrower shall reimburse Lender for all
reasonable out-of-pocket costs and expenses incurred by Lender in connection
with audits and appraisals of Borrower's books and records and such other
matters as Lender shall deem appropriate. All such out-of-pocket expenses shall
be payable on demand.

      2.7. REIMBURSEMENT OF EXPENSES. If, at any time or times regardless of
whether or not an Event of Default then exists, Lender incurs legal or
accounting expenses or any other costs or out-of-pocket expenses in connection
with (i) the negotiation and preparation of this Agreement or any of the other
Loan Documents, any amendment of or modification of this Agreement or any of the
other Loan Documents, or any sale or attempted sale of any interest herein to
any other Person; (ii) the administration of this Agreement or any of the other
Loan Documents and the transactions contemplated hereby and thereby (other than
Lender's overhead costs and expenses associated with the day to day
administration of the Loans); (iii) 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 Loan Documents or Borrower's affairs; (iv) 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 Loan Documents, including
the Account Debtors; or (v) any attempt to inspect, verify, protect, preserve,
restore, collect, sell, liquidate or otherwise dispose of or realize upon the
Collateral; then all such legal and accounting expenses, other costs and out of
pocket expenses of Lender shall be charged to Borrower. All amounts chargeable
to Borrower under this SECTION 2.7 shall be Obligations secured by all of the
Collateral, shall be payable on demand to Lender, and shall bear interest from
the date such demand is made until paid in full at the rate applicable to
Revolving Credit Loans from time to time. Borrower shall also reimburse Lender
for expenses incurred by Lender in its administration of the Collateral to the
extent and in the manner provided in SECTION 6 hereof.

      2.8. BANK CHARGES. Borrower shall pay to Lender, on demand, any and all
normal and customary fees, costs or expenses which Lender pays to a bank or
other similar institution arising out of or in connection with (i) the
forwarding to Borrower or any other Person on behalf of Borrower, or 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.

SECTION 3.  LOAN  ADMINISTRATION

      3.1. MANNER OF BORROWING REVOLVING CREDIT LOANS. Borrowings under the
credit facility established pursuant to SECTION 1 hereof shall be as follows:

            3.1.1.      LOAN REQUESTS.

                  (A) A request for a Eurodollar Loan shall be made, or shall be
deemed to be made, if Borrower gives Lender notice of its intention to borrow in
the form of EXHIBIT P hereto (a "BORROWING NOTICE"), in which notice Borrower
shall specify (i) the aggregate amount of such Eurodollar Loan, (ii) the
requested date of such Eurodollar Loan, (iii) the Applicable 

                                       8
<PAGE>
Annual Rate selected in accordance with SECTION 2.1.1, and (iv) the LIBOR
Interest Period applicable thereto. If Borrower selects a Eurodollar Loan,
Borrower shall give Lender the Borrowing Notice no later than 11:00 a.m. Dallas,
Texas time at least two (2) Business Days prior to the requested date of the
Eurodollar Loan. Notwithstanding anything herein to the contrary, Lender shall
have the right to refuse to accept a request for a Eurodollar Loan and to refuse
to make a Eurodollar Loan if at the date such request is made or such Eurodollar
Loan is to be made there exists a Default or an Event of Default.

                  (B) A request for a Base Rate Loan shall be made, or shall be
deemed to be made, in the following manner: (i) Borrower shall 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, no later than
11:00 a.m. Dallas, Texas time on the proposed borrowing date; PROVIDED, HOWEVER,
Lender shall have the right to refuse to accept such a request or make such a
Loan if at such time there exists a Default or an Event of Default; and (ii) the
becoming due of any amount required to be paid under this Agreement, under the
Term Note, the Equipment Note or any of the other Loan Documents, as principal,
accrued interest, fees or other charges, shall be deemed irrevocably to be a
request by Borrower from Lender for a Revolving Credit Loan on the due date of,
and in an aggregate amount required to pay, such principal, accrued interest,
fees or other charges and the proceeds of each such Revolving Credit Loan may be
disbursed by Lender by way of direct payment of the relevant Obligation and
shall bear interest at the rate of interest applicable to Revolving Credit Loans
(whether or not any Default, Event of Default or Out-of-Formula Condition exists
at the time of or would result from such Revolving Credit Loan). As an
accommodation to Borrower, Lender may permit telephonic requests for loans and
electronic transmittal of instructions, authorizations, agreements or reports to
Lender by Borrower. Unless Borrower specifically directs Lender in writing not
to accept or act upon telephonic or electronic communications from Borrower,
Lender shall have no liability to Borrower for any loss or damage suffered by
Borrower as a result of Lender's honoring of any requests, execution of any
instructions, authorizations or agreements or reliance on any reports
communicated to Lender telephonically or electronically and purporting to have
been sent to Lender by any individual from time to time designated by Borrower
as an authorized officer and Lender shall have no duty to verify the origin or
authenticity of any such communication.

to disburse the proceeds of each Loan requested, or deemed to be requested,
pursuant to this SECTION 3.1.2 as follows: (i) the proceeds of each Loan
requested under SECTION 3.1.1(A) or SECTION 3.1.1(B)(I) shall be disbursed by
Lender in lawful money of the United States of America in immediately available
funds, in the case of the initial borrowing, in accordance with the terms of the
written disbursement letter from Borrower, and in the case of each subsequent
borrowing, by wire transfer to such bank account as may be agreed upon by
Borrower and Lender from time to time or elsewhere if pursuant to a written
direction from Borrower; and (ii) the proceeds of each Revolving Credit Loan
requested under SECTION 3.1.1(B)(II) shall be disbursed by Lender by way of
direct payment of the relevant interest or other Obligation.

            3.1.3. AUTHORIZATION. Borrower hereby irrevocably authorizes Lender,
in Lender's sole discretion, to advance to Borrower, and to charge Borrower's
Loan Account 

                                       9
<PAGE>
hereunder as a Revolving Credit Loan, a sum sufficient to pay all interest
accrued on the Obligation during the immediately preceding month and to pay all
costs, fees and expenses at any time owed by Borrower to Lender hereunder.

      3.2. PAYMENTS. All payments with respect to any of the Obligations shall
be made to Lender on the date when due, in Dollars and in immediately available
funds, without any offset or counterclaim. 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 3.2 (in which event
the conflicting provisions of said notes or other instruments shall govern and
control), the Obligations shall be payable as follows:

            3.2.1. PRINCIPAL. Principal payable on account of Revolving Credit
Loans 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,
other than Equipment or real Property, 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 pursuant to SECTION 4 hereof; PROVIDED, HOWEVER, that if an
Out-of-Formula Condition shall exist at any time, Borrower shall, on demand,
repay the Obligations to the extent necessary to eliminate the Out-of-Formula
Condition.

            3.2.2. INTEREST. Interest accrued on the Revolving Credit Loans
shall be due on the earliest of (i) the first calendar 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,
(iii) with respect to any Eurodollar Loan, the last day of the applicable LIBOR
Interest Period, or (iv) termination of this Agreement pursuant to SECTION 4
hereof.

            3.2.3. COSTS, FEES AND CHARGES. Costs, fees and charges payable
pursuant to this Agreement shall be payable by Borrower as and when provided in
SECTION 2 hereof, to Lender or to any other Person designated by Lender in
writing.

            3.2.4. OTHER OBLIGATIONS. 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, the Other Agreements or the Security Documents, or,
if no date of payment is otherwise specified in the Loan Documents, on demand.

      3.3.  MANDATORY PREPAYMENTS.

            3.3.1. PROCEEDS OF SALE, LOSS, DESTRUCTION OR CONDEMNATION OF
COLLATERAL. If Borrower sells any of the Equipment or real Property, or if any
of the Collateral is lost or destroyed or taken by condemnation, Borrower shall
pay to Lender, unless otherwise agreed by Lender, as and when received by
Borrower and as a mandatory prepayment of either or both the Term Loan or the
Equipment Loans, as determined by Lender (or, at Lender's option, such of the
other Obligations as Lender may elect), a sum equal to the net proceeds
(including insurance payments) in excess of $500,000 received by Borrower from
such sale, loss, destruction or 

                                       10
<PAGE>
condemnation. Nothing in this SECTION 3.3.1 shall authorize Borrower to sell any
of the Collateral without Lender's prior written consent except as otherwise
expressly provided elsewhere in this Agreement.

      3.4. 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 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 6.2.6 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 or any Equipment Loan, except that
Lender may, at its option, offset such credit balance against any of the
Obligations upon and after the occurrence of an Event of Default.

      3.5. LOAN ACCOUNT. Lender shall establish an account on its books (the
"LOAN ACCOUNT") and 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, other
debits and credits, including interest and all charges and expenses properly
chargeable to Borrower.

      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 after the date each accounting is deemed to have been sent
pursuant to SECTION 11.9. Such notice shall only be deemed an objection to those
items specifically objected to therein.

      3.7.  ADDITIONAL PROVISIONS REGARDING EURODOLLAR LOANS.

            (A) Borrower may select LIBOR with respect to all or any portion of
the Loans in accordance with the provisions of SECTION 3.1.1(A) hereof and of
this SECTION 3.7; PROVIDED, HOWEVER, that (i) each Eurodollar Loan shall be in a
principal amount of not less than Two Million Dollars ($2,000,000) and, if
greater than Two Million Dollars ($2,000,000), in integral multiples of One
Million Dollars ($1,000,000), and (ii) no more than three (3) LIBOR Interest
Periods in the aggregate may be in existence at any one time. Borrower shall
select LIBOR Interest Periods with respect to Eurodollar Loans so that no LIBOR
Interest Period 

                                       11
<PAGE>
expires after the end of the Original Term. An outstanding Base Rate Loan may be
converted to a Eurodollar Loan at any time subject to the provisions of this
SECTION 3.7.

            (B) Each Eurodollar Loan shall bear interest from and including the
first day of the LIBOR Interest Period applicable thereto (but not including the
last day of such LIBOR 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 the Term Note, the Equipment Note and in SECTION 3.2.2
hereof. If at the end of a LIBOR Interest Period for an outstanding Eurodollar
Loan, Borrower has failed to deliver to Lender a new Borrowing Notice with
respect to such Eurodollar Loan or to pay such Eurodollar Loan, then such
Eurodollar Loan shall be converted to a Base Rate Loan on and after the last day
of such LIBOR Interest Period and shall remain a Base Rate Loan until paid or
until the effective date of a new Borrowing Notice with respect thereto.

            (C) 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; or
if Lender determines that (i) deposits of a type or maturity appropriate to
match fund Eurodollar Loans are not available, or (ii) LIBOR does not accurately
reflect the cost of making a Eurodollar Loan, then Lender shall promptly provide
notice to Borrower of its decision to suspend Borrower's ability to make
Eurodollar Loans and/or require Borrower to repay all Eurodollar Loans and shall
suspend the availability of Eurodollar Loans after the date of any such
determination.

            (D) If any payment of a Eurodollar Loan occurs on a date which is
not the last day of the applicable LIBOR 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 a Default or
Event of Default has occurred and is continuing, Borrower will indemnify Lender
for any loss or cost incurred by Lender resulting therefrom, including, without
limitation, any loss or cost in liquidating or employing deposits required to
fund or maintain the Eurodollar Loan.

            (E) Lender shall deliver a written statement as to the amount due,
if any, under SECTIONS 3.7(C) or (D) hereof. Such written statement shall set
forth in reasonable detail the calculations 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 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 LIBOR applicable
to such 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.

                                       12
<PAGE>
SECTION 4.  TERM  AND  TERMINATION

      4.1. TERM OF AGREEMENT. Subject to Lender's right to cease making Loans to
Borrower upon or after the occurrence of any Default or Event of Default, this
Agreement shall be in effect through December 31, 2000 (the "ORIGINAL TERM").

      4.2.  TERMINATION.

            4.2.1. TERMINATION BY LENDER. Upon at least sixty (60) days prior
written notice to Borrower, Lender may terminate this Agreement as of the last
day of the Original Term and Lender may terminate this Agreement without notice
upon or after the occurrence of an Event of Default.

            4.2.2. TERMINATION BY BORROWER. Upon at least sixty (60) 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 and all Letters of
Credit and LC Guaranties have expired or have been cash collateralized to
Lender's satisfaction. Any notice of termination given by Borrower shall be
irrevocable unless Lender otherwise agrees in writing, and Lender shall have no
obligation to make any Loans or issue or procure any Letters of Credit or LC
Guaranties on or after the termination date stated in such notice. Except as
specifically provided in SECTION 4.2.3 below (with respect to prepayment of the
Term Loan), Borrower may elect to terminate this Agreement in its entirety only.
Except as specifically provided in SECTION 4.2.3 below (with respect to
prepayment of the Term Loan), no section of this Agreement or type of Loan
available hereunder may be terminated singly.

            4.2.3. TERMINATION CHARGES. On the effective date of termination of
this Agreement for any reason, Borrower shall pay to Lender (in addition to the
then outstanding principal, accrued interest and other charges owing under the
terms of this Agreement and any of the other Loan Documents), as liquidated
damages for the loss of the bargain and not as a penalty, an amount equal to
2.0% of the Total Credit Facility if termination occurs at any time on or prior
to March 31, 1999; and 1.0% of the Total Credit Facility if termination occurs
at any time on or prior to March 31, 2000. If termination occurs on or at any
time after March 31, 2000, no termination charge shall be payable. In addition,
if the Term Loan and/or the Equipment Loans are prepaid in full or in part
solely from the proceeds of a public offering of capital stock of ATP, no
termination charge shall be payable in respect of the principal amount so
prepaid.

            4.2.4. EFFECT OF TERMINATION. All of the Obligations shall be
immediately due and payable upon the termination date stated in any notice of
termination of this Agreement. All undertakings, agreements, covenants,
warranties and representations of Borrower contained in the Loan Documents shall
survive any such termination and Lender shall retain its Liens in the Collateral
and all of its rights and remedies under the Loan Documents notwithstanding such
termination until Borrower has paid the Obligations to Lender, in full, in
immediately available funds, together with the applicable termination charge, if
any. Notwithstanding the payment in full of the Obligations, Lender shall not be
required to terminate its security interests in the 

                                       13
<PAGE>
Collateral unless, with respect to any loss or damage Lender may incur as a
result of dishonored checks or other items of payment received by Lender from
Borrower or any Account Debtor and applied to the Obligations, Lender shall, at
its option, (i) have received a written agreement, executed by Borrower and by
any Person whose loans or other advances to Borrower are used in whole or in
part to satisfy the Obligations, indemnifying Lender from any such loss or
damage; or (ii) have retained such monetary reserves and Liens on the Collateral
for such period of time as Lender, in its reasonable discretion, may deem
necessary to protect Lender from any such loss or damage.

SECTION 5.  SECURITY INTERESTS

      5.1 SECURITY INTEREST IN COLLATERAL. To secure the prompt payment and
performance to Lender of all of the Obligations, each Borrower hereby grants to
Lender a continuing security interest in and Lien upon all of each Borrower's
assets, including all of the following Property and interests in Property of
Borrower, whether now owned or existing or hereafter created, acquired or
arising and wheresoever located:

            (i)    All Accounts;

            (ii)   All Inventory;

            (iii)  All Equipment;

            (iv)   All General Intangibles;

            (v)    All investment property (as defined in SECTION 9.115 of the
      Code);

            (vi)   All real Property;

            (vii)  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 or Affiliate of Lender;

            (viii) All accessions to, substitutions for and all replacements,
      products and cash and non-cash proceeds of (i) through (vii) above,
      including proceeds of and unearned premiums with respect to insurance
      policies insuring any of the Collateral; and

            (ix)  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 (i) through (viii)
      above.

      5.2 CROSS-COLLATERALIZATION. Each Borrower agrees that the Collateral
pledged by such Borrower hereunder shall secure all of the Obligations of the
Borrower. Upon and after a Default or an Event of Default by any Borrower,
Lender may pursue all rights and remedies that Lender may have against all or
any part of the Collateral regardless of which Borrower has legal 

                                       14
<PAGE>
title to such Collateral. Each Borrower hereby acknowledges that this
cross-collateralization of the Collateral owned by such Borrower is in
consideration of Lender extending the credit hereunder and is mutually
beneficial to each Borrower.

      5.3. LIEN PERFECTION; FURTHER ASSURANCES. Borrower shall execute such
UCC-1 financing statements as are required by the Code and such other
instruments, assignments or documents as are necessary to perfect Lender's Lien
upon any of the Collateral and shall take such other action as may be required
to perfect or to continue the perfection of Lender's Lien upon the Collateral.
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. At Lender's request, Borrower shall also promptly
execute or cause to be executed and shall deliver to Lender any and all
documents, instruments and agreements deemed necessary by Lender to give effect
to or carry out the terms or intent of the Loan Documents.

      5.4. LIEN ON REALTY; COLLATERAL ASSIGNMENTS OF LEASES. The due and
punctual payment and performance of the Obligations shall also be secured by the
Lien created by each Mortgage upon all real Property of Borrower described
therein. The Mortgage shall be executed by Borrower in favor of Lender and shall
be duly recorded, at Borrower's expense, in each office where such recording is
required to constitute a fully perfected Lien on the real Property covered
thereby. Borrower shall deliver to Lender, at Borrower's expense, mortgagee
title insurance policies issued by a title insurance company satisfactory to
Lender, which 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 all currently
existing as-built survey prints of the real Property, as Lender and its counsel
may request relating to the real Property subject to each Mortgage. The due and
punctual payment and performance of the Obligations shall also be secured by
each Collateral Assignment of Lease of the leasehold interest of Technical
Products in all real Property described therein. Each Collateral Assignment of
Lease shall be executed by Technical Products in favor of Lender and shall be
duly recorded, at Borrower's expense, in each office where such recording is
required to constitute a fully perfected Lien on the leasehold interest of
Technical Products in the real Property covered thereby.

SECTION 6.  COLLATERAL ADMINISTRATION

      6.1.  General

            6.1.1. 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 shall at all times be kept by Borrower
and its Subsidiaries at one or more of the business locations set forth in
EXHIBIT B hereto and shall not, without the prior written approval of Lender, be
moved therefrom, except prior to an Event of Default and Lender's acceleration
of the maturity of the Obligations in consequence thereof, for (i) sales of
Inventory in the ordinary 

                                       15
<PAGE>
course of business and (ii) removals in connection with dispositions of
Equipment that are authorized by SECTION 6.4.2 hereof.

            6.1.2. INSURANCE OF COLLATERAL. Borrower shall maintain and pay for
insurance upon all Collateral wherever located and with respect to Borrower's
business, covering casualty, hazard, public liability and such other risks in
such amounts and with such insurance companies as are reasonably satisfactory to
Lender. Borrower shall deliver the originals or certified copies of such
policies to Lender with satisfactory lender's loss payable endorsements, which
policies shall name Lender as sole loss payee, assignee or additional insured,
as appropriate. 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 specifying that the interest of Lender shall not be impaired or
invalidated by any act or neglect of Borrower or the owner of the Property or 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 its option, but shall not be required to, procure the same and charge
Borrower therefor. Borrower agrees to deliver to Lender, promptly as rendered,
true copies of all reports made in any reporting forms to insurance companies.

            6.1.3. PROTECTION OF COLLATERAL. All expenses of protecting,
storing, warehousing, insuring, handling, maintaining and shipping the
Collateral, any and all excise, property, sales and use taxes imposed by any
Applicable Law on any of the Collateral or in respect of the sale thereof, and
all other payments required to be made by Lender to any Person to realize upon
any Collateral 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 Borrower therefor. Lender shall not
be liable or responsible in any way for the safekeeping of any of the 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.

      6.2.  ADMINISTRATION OF ACCOUNTS.

            6.2.1. RECORDS, SCHEDULES AND ASSIGNMENTS OF ACCOUNTS. Borrower
shall keep accurate and complete records of its Accounts and all payments and
collections thereon and shall submit to Lender on such periodic basis as Lender
shall request a sales and collections report for the preceding period, in form
satisfactory to Lender. On or before the twentieth day of each month from and
after the date hereof, Borrower shall deliver to Lender, in form acceptable 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. In
addition, if Accounts in an aggregate face amount in excess of $100,000 become
ineligible because they fall within one of the specified categories of

                                       16
<PAGE>
ineligibility set forth in the definition of Eligible Accounts or otherwise
established by Lender, Borrower shall notify Lender of such occurrence on the
first Business Day following the day such occurrence becomes known to Borrower
and the Borrowing Base shall thereupon be adjusted to reflect such occurrence.
If requested by Lender, Borrower shall execute and deliver to Lender agings and
formal written assignments of all of its Accounts weekly or daily, which shall
include all Accounts that have been created since the date of the last
assignment, together with copies of invoices or invoice registers related
thereto.

            6.2.2. DISCOUNTS, ALLOWANCES, DISPUTES. If Borrower grants any
discounts, allowances or credits that are not shown on the face of the invoice
for the Account involved, Borrower shall report such discounts, allowances or
credits, as the case may be, to Lender as part of the next required Schedule of
Accounts. If any amounts due and owing in excess of $100,000 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. Upon and after the occurrence of an Event
of Default, Lender shall have the right to settle or adjust all disputes and
claims directly with the Account Debtor and to compromise the amount or extend
the time for payment of the Accounts upon such terms and conditions as Lender
may deem advisable, and to charge the deficiencies, costs and expenses thereof,
including attorney's fees, to Borrower.

            6.2.3. TAXES. 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 Borrower therefor; PROVIDED, HOWEVER, that Lender shall
not be liable for any such taxes to any governmental taxing authority that may
be due by Borrower.

            6.2.4. ACCOUNT VERIFICATION. Whether or not a Default or an Event of
Default has occurred, any of Lender's officers, employees or agents 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.

            6.2.5. MAINTENANCE OF DOMINION ACCOUNT. Borrower shall maintain a
Dominion Account pursuant to a lockbox arrangement acceptable to Lender with
such banks as may be selected by Borrower and be acceptable to Lender; provided,
however, Borrower may at its option elect to terminate the Dominion Account upon
providing Lender five (5) days prior written notice of its election to terminate
the Dominion Account. Borrower shall issue to any such banks an irrevocable
letter of instruction directing such banks to deposit all payments or other
remittances received in the lockbox to the Dominion Account for application on
account of the Obligations. All funds deposited in the Dominion Account shall
immediately become the property of Lender and Borrower shall obtain the
agreement by such banks in favor of Lender to waive any offset rights against
the funds so deposited.

                                       17
<PAGE>
            6.2.6. COLLECTION OF ACCOUNTS; PROCEEDS OF COLLATERAL. To expedite
collection, Borrower shall endeavor in the first instance to make collection of
its Accounts for Lender. All remittances received by Borrower in respect of
Accounts, together with the proceeds of any other Collateral, 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 kind in the Dominion
Account. Lender retains the right at all times after the occurrence of a Default
or an Event of Default 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.

      6.3.  ADMINISTRATION OF INVENTORY.

            6.3.1. RECORDS AND REPORTS OF INVENTORY. Borrower shall keep
accurate and complete records of its Inventory. Borrower shall furnish Lender
Inventory reports in form and detail satisfactory to Lender at such times as
Lender may request, but at least once each month, not later than the twentieth
day of such month. In the event Borrower conducts a physical inventory of its
Inventory, Borrower shall provide to Lender a report based on each such physical
inventory promptly thereafter, together with such supporting information as
Lender shall request.

            6.3.2. RETURNS OF INVENTORY. Borrower shall not return any of its
Inventory to a supplier or vendor thereof, or any other Person, whether for
cash, credit against future purchases or then existing payables, or otherwise,
unless (i) such return is in the ordinary course of business of Borrower and
such Person, (ii) no Default or Event of Default exists or would result
therefrom, (iii) the return of such Inventory will not result in an
Out-of-Formula Condition, (iv) if the value of all Inventory returned in any
month exceeds $250,000, Borrower promptly notifies Lender thereof, and (v) any
payments received by Borrower in connection with any such return is promptly
turned over to Lender for application to the Obligations.

      6.4.  ADMINISTRATION OF EQUIPMENT.

            6.4.1. RECORDS AND SCHEDULES OF EQUIPMENT. Borrower shall keep
accurate records itemizing and describing the kind, type, quality, quantity and
value of its Equipment and all dispositions made in accordance with SECTION
6.4.2 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. Immediately on request therefor by Lender, Borrower shall deliver to
Lender any and all evidence of ownership, if any, of any of the Equipment.

            6.4.2. 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 (i) 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 $500,000 or less, provided that all proceeds thereof are
remitted to Lender for application to the Loans, or (ii) replacements of
Equipment that is substantially worn, damaged or obsolete with Equipment of like
kind, function and value, provided that the replacement Equipment shall

                                       18
<PAGE>
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 that are not Purchase Money Liens, and Borrower shall
have given Lender at least five (5) days' prior written notice of such
disposition.

            6.4.3. CONDITION OF EQUIPMENT. 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 and in form acceptable to

            10.1.18. DOMINION ACCOUNT. Borrower shall fail to maintain a
Dominion Account or shall notify Lender that it intends to terminate its
existing Dominion Account.

      10.2. 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 3.2 hereof, upon or at any time after the
occurrence of an Event of Default, all or any portion of the Obligations shall,
at the option of Lender and without presentment, demand protest or further
notice by Lender, become at once due and payable and Borrower shall forthwith
pay to Lender, the full amount of such Obligations; PROVIDED, HOWEVER, that upon
the occurrence of an Event of Default specified in SECTION 10.1.10 hereof, all
of the Obligations shall become automatically due and payable without
declaration, notice or demand by Lender.

      10.3. OTHER 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:

            10.3.1. 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 shall be in addition to any other rights or remedies contained in
this Agreement or any of the other Loan Documents, and none of which shall be
exclusive.

            10.3.2. The right to take immediate possession of the Collateral,
and to (i) 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) enter any premises where any of
the Collateral shall be located and to keep and store the Collateral on said
premises until sold (and if said premises be the Property of Borrower, then
Borrower agrees not to charge Lender for storage thereof).

                                       37
<PAGE>
            10.3.3. The right to sell or otherwise dispose of all or any
Collateral 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 sole discretion, may deem advisable. Borrower agrees that any requirement of
notice to Borrower of any proposed public or private sale or other disposition
of Collateral by Lender shall be deemed reasonable notice thereof if given at
least 10 days prior thereto, and such sale may 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 the Collateral, or any part thereof, for
cash, credit or any combination thereof, and Lender may purchase all or any part
of the 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. The proceeds realized from the sale of any Collateral
may be applied, after allowing 2 Business Days for collection, first to the
costs, expenses and attorneys' fees incurred by Lender in collecting the
Obligations, in enforcing the rights of Lender under the Loan Documents and in
collecting, retaking, completing, protecting, removing, storing, advertising for
sale, selling and delivering any Collateral, second to the interest due upon any
of the Obligations; and third, to the principal of the Obligations. If any
deficiency shall arise, each Borrower shall remain jointly and severally liable
to Lender therefor.

            10.3.4. The right to exercise all of Lender's rights and remedies
under the Mortgage with respect to any real Property forming a part of the
Collateral.

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, trade names, 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.

            10.3.5. Lender may, at its option, require Borrower to deposit with
Lender funds equal to the LC Amount and, if Borrower fails to promptly make such
deposit, Lender may advance such amount as a Revolving Credit Loan (whether or
not an Out-of-Formula Condition is created thereby). Any such deposit or advance
shall be held by Lender as a reserve to fund future payments on such LC
Guaranties and future drawings against such Letters of Credit. At such time as
all LC Guaranties have been paid or terminated and all Letters of Credit have
been drawn upon or expired, any amounts remaining in such reserve shall be
applied against any outstanding Obligations, or, if all Obligations have been
indefeasibly paid in full, returned to Borrower.

      10.4. REMEDIES CUMULATIVE; NO WAIVER. All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the other Loan Documents, or in any
document referred to herein or contained in any agreement supplementary hereto
or in any schedule or in any Guaranty Agreement 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 

                                       38
<PAGE>
of any of the terms, covenants, conditions, or agreements of Borrower herein
contained. The failure or delay of Lender to require strict performance by
Borrower of any provision of this Agreement or 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 performance, Liens, rights, powers and remedies, but all such
requirements, 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. None of the
undertakings, agreements, warranties, covenants and representations of Borrower
contained in this Agreement or any of the other Loan Documents and no Event of
Default by Borrower under this Agreement or any other Loan Documents 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.

      11.3. INDEMNITY. BORROWER HEREBY INDEMNIFIES, HOLDS HARMLESS, AND SHALL
DEFEND LENDER AND ITS DIRECTORS, OFFICERS, AGENTS, COUNSEL AND EMPLOYEES
("INDEMNIFIED PERSONS") FROM AND AGAINST ANY AND ALL LOSSES, LIABILITIES,
DAMAGES, COSTS, EXPENSES, SUITS, ACTIONS AND PROCEEDINGS ("LOSSES") EVER
SUFFERED OR INCURRED BY ANY INDEMNIFIED PERSON ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR ANY OTHER TRANSACTION CONTEMPLATED HEREBY, INCLUDING, WITHOUT
LIMITATION, ANY LOSSES CAUSED BY THE NEGLIGENCE OF SUCH INDEMNIFIED PERSON, BUT
NOT INCLUDING ANY (I) LOSSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH INDEMNIFIED PERSON OR (II) LOSSES SUFFERED BY ANY INDEMNIFIED
PERSON AS THE RESULT OF ANY ACTION, SUIT OR PROCEEDING INSTITUTED AGAINST SUCH
INDEMNIFIED PERSON BY ANOTHER INDEMNIFIED PERSON, AND BORROWER SHALL REIMBURSE
LENDER AND EACH OTHER INDEMNIFIED PERSON FOR ANY EXPENSES (INCLUDING IN
CONNECTION WITH THE INVESTIGATION OF, PREPARATION FOR OR DEFENSE OF ANY ACTUAL
OR THREATENED CLAIM, ACTION OR PROCEEDING ARISING THEREFROM, INCLUDING ANY SUCH
COSTS OF RESPONDING TO DISCOVERY REQUESTS OR SUBPOENAS, REGARDLESS OF WHETHER
LENDER OR SUCH OTHER INDEMNIFIED PERSON IS A PARTY THERETO). WITHOUT LIMITING
THE GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY CLAIMS
ASSERTED AGAINST LENDER OR ANY OTHER INDEMNIFIED PERSON BY ANY PERSON UNDER

<PAGE>
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. BORROWER MAY SELECT COUNSEL WITH RESPECT TO
ANY LOSSES; PROVIDED, HOWEVER, EACH INDEMNIFIED PERSON SHALL HAVE THE RIGHT TO
MONITOR THE PROGRESS OF ANY CLAIMS, SUITS AND ADMINISTRATIVE PROCEEDINGS
DEFENDED BY BORROWER HEREUNDER WITH COUNSEL OF SUCH INDEMNIFIED PERSON'S CHOICE,
OR CONDUCT ITS DEFENSE THROUGH COUNSEL OF SUCH INDEMNIFIED PERSON'S CHOICE, IN
THE EVENT THAT (I) SUCH INDEMNIFIED PERSON DETERMINES IN GOOD FAITH THAT THE
CONDUCT OF ITS DEFENSE BY BORROWER COULD BE MATERIALLY PREJUDICIAL TO SUCH
INDEMNIFIED PERSON'S INTERESTS OR THAT OTHER REASONABLE GROUNDS EXIST WHICH
DEMONSTRATE A LACK OF EFFECTIVENESS OR HIGH LEVEL OF QUALITY IN THE CONDUCT OF
SUCH DEFENSE BY BORROWER, AND (II) PRIOR TO RETAINING SUCH COUNSEL FOR SUCH
PURPOSE, SUCH INDEMNIFIED PERSON SHALL CONSULT WITH BORROWER AND SHALL ATTEMPT
IN GOOD FAITH TO AGREE UPON COUNSEL TO CONDUCT THE DEFENSE ON BEHALF OF BORROWER
AND SUCH INDEMNIFIED PERSON, AND IN EACH CASE THE FEES AND DISBURSEMENTS OF SUCH
COUNSEL SHALL BE PAID BY BORROWER; PROVIDED, HOWEVER, THAT IF SUCH MUTUAL
AGREEMENT IS NOT REACHED WITHIN A REASONABLE TIME ON SELECTING COUNSEL, THEN
SUCH INDEMNIFIED PERSON MAY RETAIN ITS OWN COUNSEL AT BORROWER'S EXPENSE.
NOTWITHSTANDING ANY CONTRARY PROVISION OF THIS AGREEMENT, THE OBLIGATION OF
BORROWER UNDER THIS SECTION 11.3 SHALL SURVIVE THE PAYMENT IN FULL OF THE
OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

      11.4. MODIFICATION OF AGREEMENT; SALE OF INTEREST. This Agreement may not
be modified, altered or amended, except by an agreement in writing signed by
Borrower and Lender. Borrower may not sell, assign or transfer any interest in

any portion thereof, including Borrower's rights, title, interests, remedies,
powers, and duties hereunder or thereunder. Borrower hereby consents to Lender's
participation, sale, assignment, transfer or other disposition, at any time or
times hereafter, of this Agreement and any of the other Loan Documents, or of
any portion hereof or thereof, including 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 if it were "Lender" hereunder and
Lender shall be relieved of all obligations hereunder upon any such assignment.
Borrower agrees that it will use its best efforts to assist and cooperate with
Lender in any manner reasonably requested by Lender to effect the sale of
participations in or assignments of any of the Loan Documents or any portion
thereof or interest therein, including assisting in the preparation of
appropriate disclosure documents. Borrower further agrees that Lender may
disclose credit information regarding Borrower and its Subsidiaries to any
potential participant or assignee.

      11.5. SEVERABILITY. Wherever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under

provision of this Agreement shall be prohibited by or invalid under Applicable
